USA, Az: Exotic New Mars Images From Orbiting Telephoto Studio

from: pwbmspac @ . . .

Here is a link to some recently released Mars images. Several look like the kind of imagery we come to expect to find in National Geographic Magazine.

The situation needs to be improved. In the event of success, an indicator at such a future date, you may expect to see research teams exploring such far away locations supported in large part by institutions such as the National Geographic organization.

Notice that the comparable USA national effort is in declining health. A decision after presidential review has canceled — for at least the next year – – the government funding of launch systems development, such as would be needed for human missions beyond earth orbit, (An editorial in Popular Science Magazine, earlier in 2010, suggested to readers this decision might, on the other hand, be good news for a private market in development / operation of space launch services.)

Exotic New Mars Images From Orbiting Telephoto Studio

A new batch of sharp Martian close-ups from NASA’s HiRISE camera were released on Sept. 1. HiRISE (High Resolution Imaging Science Experiment) has been circling Mars on the Mars Reconnaissance Orbiter for four years now, taking dramatic photos of the red planet with a telephoto lens to make any paparazzi jealous. The camera can focus on objects the size of a beach ball from more than 180 miles away.

The 236 new images, taken between July 8 and July 31, cover the planet practically from pole to pole. They zoom in on terrain ranging from volcanic cones to cratered planes, from wind-swept dunes to crusts of ice. The images even capture evidence of ongoing geological processes on Mars today, like fresh craters that may have formed between January and June of this year.

Above: These volcanic cones were formed by hot lava running over water or ice. The heat from the lava boiled the water underneath, and the water burst upwards in an exploding bubble of lava. The explosion threw chunks of molten and solid lava into the air to gather into the cones. These cones are similar in size and shape to cones found in Iceland.

India: Indian researcher shows faults in EVMs, gets arrested

fromYona F Maro

Bangalore: Hari Prasad, the Managing Director of Netindia an Indian
research and development firm, on his refusal to disclose an anonymous
source who provided an electronic voting machine to a team of security
researchers was arrested. He and other researchers have long
questioned the security of India’s paperless electronic voting
machines. Despite repeated reports of election irregularities and
concerns about fraud, the Election Commission of India insists that
the machines are tamper-proof.

As per the reports Prasad was questioned Saturday morning at his home
in Hyderabad by authorities who wanted to know the identity of the
source who gave the voting machine to the research team. Prasad was
ultimately arrested and taken to Mumbai, though reportedly hadn’t been
charged with a crime.

In 2009, the commission publicly challenged Prasad to show that
India’s voting machines could be compromised, but refused to give him
access to the machines to perform a review. Earlier this year, an
anonymous source provided an Indian voting machine to a research team
led by Prasad, The team exposed security flaws that could allow an
attacker to change election results and compromise ballot secrecy.
They published a paper detailing their findings.

The Election Commission of India should have given researchers access
to the voting machines in the first place. Prasad is a respected
researcher who helped to discover a critical flaw in India’s voting
system. He and his fellow researchers would never have been able to
document the weaknesses in India’s voting machines without the help of
their anonymous source. This is precisely why anonymity is important:
it allows people to make important contributions to the public
dialogue without fear of retribution.

Kenya: How to save Africans from unnecessary deaths.

Good people,

Africa, Kenya included is lagging behind in scientific industrial development. Africa or Kenya is known to copy the rest of the developed world now for a long time. Africa has not been on the frontline on any new scientific adventure. I will stick only to a small field and try to convince you that we are not yet smart enough despite the education knowledge we have harboured since independence or before that independence time. Kenya for example have a lot of highly educated lots, but the country have failed completely up to today to exploit most of the best brains in the country. Most of the best brains in the country are busy trying to make the ends meet by constant routine manual work to get food for their family and pay school fees for their off springs. The ones who have left the country are working for foreign countries and therefore contributes to the development of those host nations, not Kenya.

Take for example the medical field: with the present knowledge we do know that even identical twins are not truly identical. Although to strangers they look much a like,relatives and friends usually have no problem telling them a part, even from a distance, but these twins have their own personalities and completely their own genomes. Malaria disease have been a pain in the ass for an African man or woman now for a long time; devices have been suggested, business men have made billions of dollars out of just mosquito nets alone, but an African man or child is still being buried everyday because of this malarian problem. Drugs have been given to an African man by whites, now even Chinese but does the African get help from these drugs?. Some get some do not get and end up dying.

Africans still lack the study on their genetic structure, we need to do a complete genome sequences of our population. Through this we will understand our people`s diversity. We should study mitochondrial and sets of nuclear in our cells. Just being a bantu, let say a kikuyu does not necessarily mean that you have the same genome sequences with a bantu who is a kisii, or a kamba when it comes to diseases or treating some particular diseases. Or being a nilotic luo and the other a nilotic kalenjin, or masai or acholi does not mean you have the same genomes.

Why is genome knowledge important?. Well today we do know that there is lack of malaria-resistance alleles in the Bushmen population and also some other Africans which might have significant consequences on treating this malarian disease and also in the development of a drug for malaria. We know today that the Bushmen seem to be, on average, more different from each other than, for example, a European and an Asian. So folks drugs we sometimes get blindly from foreign farms for any disease to be used in Africa might not be well for our African genome or drug metabolism and disease resistance. But how do we go about this if we use almost all our tax-payers money to pay Mps, ministers, presidents salary or buy them the best motorcars in the planet etc and some of our resources are also being stolen and banked a broad?.

This is not all we know now from medical point of view this is just a tip of the iceberg in other diseases and environmental changes or mutation. I do look to the day we Africans will come up with a non copy laboratories and good scientific facilities to do good research to enrich our population and academic egos.

Is Hell exothermic or endothermic

From: Paul Nyandoto

Guys,

Hell is just intermediary place where discipline takes place before you are taken to heaven. Which God would like his creation to burn forever?. Christianity and Islam says Hell is a fiery and painful, inflicting guilt and suffering. I say Hell is a cold gloomy and just a stage to paradise you have to pass if you were a little crazy on earth before you go to heaven . The only permanent inhabitants of Hell are Demons not human beings, do you get it?. The old description of Hell is not worthy nowadays since on earth here some people do go almost the same suffering. Have you forgotten the petrol Tank which burnt people, the sufferings in slums, the poverty in Africa. HELL= INTERMEDIARY STAGE. In Hell you are also given chances to finish the unfinished business you had on earth here before your death; let say you were hit by a bus before you finished smoking your marijuana, you get there another chance to realise whether smoking was bad or good.

Paul Nyandoto.

THE STUDENT WHO RECEIVED THE ONLY “A+”
Did The Professor Have A Choice…?
The following is an actual question given on a University of Nairobi
chemistry mid-term.

The answer by one student was so “profound” that the professor shared it
with colleagues, via the Internet, which is, of course, why we now have
the pleasure of enjoying it as well:

Bonus Question: Is Hell exothermic (gives off heat) or endothermic
(absorbs heat)?

Most of the students wrote proofs of their beliefs using Boyle’s Law
(gas cools when it expands and heats when it is compressed) or some
variant.

P1V1 = P2V2

One student, however, wrote the following:

First, we need to know how the mass of Hell is changing in time. So we
need to know the rate at which souls are moving into Hell and the rate
at which they are leaving. I think that we can safely assume that once a
soul gets to Hell, it will not leave. Therefore, no souls are leaving.
As for how many souls are entering Hell, let’s look at the different
religions that exist in the world today. Most of these religions state
that if you are not a member of their religion, you will go to Hell.
Since there is more than one of these religions and since people do not
belong to more than one religion, we can project that all souls go to
Hell.

With birth and death rates as they are, we can expect the number of
souls in Hell to increase exponentially. Now, we look at the rate of
change of the volume in Hell because Boyle’s Law states that in order
for the temperature and pressure in Hell to stay the same, the volume of
Hell has to expand proportionately as souls are added.

This gives two possibilities:
1. If Hell is expanding at a slower rate than the rate at which souls
enter Hell, then the temperature and pressure in Hell will increase
until all Hell breaks loose.

2. If Hell is expanding at a rate faster than the increase of souls in
Hell, then the temperature and pressure will drop until Hell freezes
over. So which is it?

If we accept the postulate given to me by Julie during my Freshman year
that, “It will be a cold day in Hell before I sleep with you,” and take
into account the fact that I slept with her last night, then number two
must be true, and thus I am sure that Hell is exothermic and has already
frozen over.

The corollary of this theory is that since Hell has frozen over, it
follows that it is not accepting any more souls and is therefore,
extinct……leaving only Heaven, thereby proving the existence of a
divine being which explains why, last night, Julie kept shouting Oh my
God.”

Nigeria: Nation Aims To Put Africans In Space

from pwbmspac

The cited publication points to yet another nation becoming interested in the valuable frontier of outer space.

– – – – – – – – – – –

Nigeria really does have a space agency. The west African nation’s National Space Research and Development Agency is already celebrating its 10th anniversary. And as America and Europe’s space agencies set their sights on joint exploration of Mars, Nigeria has big plans of its own: It wants to send a Nigerian up into space in 2015, making Nigeria home to the first black African astronaut.

perpetual free energy

From: maina ndiritu

Guys , any thoughts on the prospects of discovering perpetual free energy ? the idea has been there for decades and research on the matter has been an on-going vision, it is believed that Tesla [ the scientist] had discovered a way to split electricity in two Ethers thereby creating the first limitless free energy.

However the American government on the death of Tesla confiscated all his discoveries , it was in the war time years and they thought his brilliant technology was a threat to the state .

After the war they did not release the materials so as to enable study and research, supposedly It went down bad with the major power producers .

With his discoveries , it would have been possible to power the entire world from a single source , he had proposed Niagara falls.

Imagine a world where there would be free energy, that would surely upset a lot of conglomerates and change the geopolitical landscape

Uganda: The country has doubled its power output and almost hitting the national target

Business and Economic News By Leo Odera Omolo

UGANDA’S power output has almost doubled in the past five years as the country tries to satisfy increasing demand that is driven by robust economic growth.

The third largest economy in the region produces 591MW, up from the 265MW previously. This has boosted power supply, making the economy more competitive.

“Investments in the sector have increased, attracting local and international players because there is transparency,” Frank Sebbowa, the Electricity Regulatory Authority, said.

The development comes on the back of a deliberate strategy in tackling electricity demand head-on. The old approach involved ‘chasing’ demand forecasts from behind through attracting local, foreign, public and private investors into the sector.

New power plants have been installed in Tororo, Namanve and Mutundwe in Kampala. This is on top of hydro-power complex with installed capacity to generate 480MW at Jinja. Power generation from small hydro-power plants is in the pipeline.

While some of the projects are near completion, others are awaiting commissioning. Uganda relies on hydro-energy to meet 90% of its electricity needs, but drought has cut capacity at the main power dams in Jinja.

However, due to the change in strategy, the country hopes to increase power generation from other renewable sources. Sugar companies, Kakira and Kinyara, are producing electricity from cane wastes.

This is not only aimed at catering for the desired pace of economic development, but also to ensure that electricity reaches every part of the country.

“There has been increased search for alternative sources of energy, including utilising the mini-hydro stations, generation from bagasse, garbage and solar-thermal projects,” Sebbowa said.

“The reforms have yielded positive results like increased access to electricity. This transforms into better standards of living.” However, there is still a need to migrate from diesel power generation to heavy fuel oil in the short-to-medium-term to reduce power prices.

“There is need to quickly harness our local oil resources to get cheaper heavy fuel oil,” the regulator observed. “We must also address system losses and reduce tariffs through re-negotiating of the allowed losses.”

Sorting out the country’s power problems is vital as the economy struggles to compete with Kenya and Tanzania for a sizable share in the coming East African Community common market.

The biggest indirect cost to firms operating in Kenya is disruptions in power supply. Attracting foreign investors will be hard since electricity prices are still high compared to the neighbouring economies.

Tanzania: The nation plans to build its nuclear power plant in the near future

Economic and Business News By Odera Omolo In Kisumu City.

REPORTS emerging from Dar Es Salaam, says Tanzania is planning to build a nuclear power plant in the near future with the technical backing of a South African and French multinational companies.

It would be the first nuclear plant of its kind in the Eastern African region. This is following a move by South Areva, a South African multinational firm, which is a member of the French multinational Areva Groups to bid to its construction.

Currently, the country, which depends on hydro-electric power to produce electricity, suffers from frequent acute power shortage.

The chairman of Areva South Africa Mohamed Madhi was recently in Dar-Es –Salaam from where he disclosed the plans to newsmen. He said his firm was seeking opportunities in East Africa to invest in nuclear power production.

He explained that Areva will produce clean energy in Tanzania though the construction of nuclear power plant pending the conclusion of negotiations with the government of that country.

“Areva is one of the leading companies that will be bidding for contracts to build energy capability in Tanzania,’ said Madhi. The firm is also a leading global nuclear energy with integrated capability across the full nuclear energy cycle from mining of uranium, to building of power stations, transmission and distribution of electricity and recycling and disposal of nuclear waste.

According to Madhu, South Africa, is currently working on a capital expansion program that will treble its power generation capacity from the current 38,000MW to about 80,00MW.

“Nuclear is expected to to form a significant portion of the energy mix in three projected capital expansion plan” Madhu said, adding that in the last capital expansion program the government anticipated that nuclear would form over 30 per cent of the new-built program.

According to Areva, nuclear is currently seen as a cost-effective environmentally friendly and relevant development energy option. Globally, it says, there is resurgence of interest in nuclear energy ,referred to in the industry as the “Nuclear Renaissance driven by the growing demand for energy among the fast growing emerging economic powers India and China.

It is also driven b the climate change issue, as other ‘base-load “option, coal fired power stations- is increasingly seen as a carbon intensive.

Madhu said the African continent ha energy resources-uranium solar, hydro, geothermal coal and gas which and underdeveloped.

However, experts at the Arusha-based Tanzania Atomic Energy Commission say extensive preparation are needed before the country can and process uranium.

The Commission’s director Prof. Idi Mkilaha in a recent interview with the EASTRAFRICAN that according to the International Atomic Energy Agency, baseline studies to assess the current level of contamination need to be made besides the mining regulations, there are regulations on safety and safeguard matters to consider.

Asked about the generation of electricity from nuclear, Prof Mkilaha said mining uranium and electricity generation are two different things.

“Major steps towards nuclear power plant development involve energy planning and analysis to establish and predict the optimum energy mix for the country in the short and long term,” he added.

Further steps include developing safeguards and nuclear regulatory framework and infrastructure, carrying out self-assessment in terms of the basic infrastructure for nuclear development and implementation, and human resources capacity development in nuclear technology.

The country also needs to carry out stakeholder and community education on nuclear power plant and its implications, identifying suitable and appropriate technology, site and nuclear power plant vendors, construction of nuclear power plant, and finally commissioning, monitoring and reviews of future development.

Prof. Mkilaha said uranium investment can take between 10 and 20 years to start paying back and as such economic benefits must be planned carefully before any commitment is made.

Blogosphere: Sony PS3 stops supporting Linux

from: PowerBeamSpacer

Mid May 2010 I came across a notable info-tech news item. Recall that Play Station 3, by Sony, has in recent times supported a feature whereby another operating system could be run on that hardware / software environment. Linux versions are notable examples.

Current news is that the vendor has now moved to stop supporting the ability for system owners to employ Linux operating system and associated open source applications. It is the most recent downloadable firmware update which implements this action. Unless data accessed via Linux, residing in that respective hard drive partition, such data would be lost upon update.

See link, (http://www.linuxinsider.com/story/Hacks-Counter-Hacks-and-the-Linux-Free-PS3-69687.html?wlc=1274034674), and further links contained therein, for further info.

I agree with that article’s writer that Sony’s action in this matter is a bad move. It is one which would likely discourage me from considering an option to purchase that system. In general, I stand In Favor of open source software apps.

Tanzania Should have a Robust patent Protection System

Are Tanzanian lawyers paying any attention to patent practice? Why are they not collaborating with Tanzanian scientists and engineers to develop a robust patent protection system? While our lawyers are enmeshed in land cases, election/chieftaincy petitions and petty politics, the legal minds of other nations are moving forward, in tandem with their inventors, leaving us behind like paralytic consumers of technology.

If I wasn’t a Tanzanian, maybe I wouldn’t have any interest in the affairs of that country. For example, I don’t know what Liberian leaders tell their citizens. As far as I am concerned, whatever Ugandan engineers tell their political leaders does not interest me so much. But I care for Tanzania and read about my beloved country everyday, thanks to the power of technology.

Speaking of technology, I’ve read so much about the “achievements” of Tanzanian engineers, scientists and technologists that my head spins. We have been hearing such claims or variations thereof since 1961! Who is fooling who?

For those who care to know, the technological development of any nation is directly proportional to her patent practice. Patent law is designed to protect innovative scientific inventions. When you pick up your cell phone, which happens to be the most prolific invention in the hands of Tanzanians today, the parts used to make them are protected by patents from one or more countries. The maker of the cell phone, for example, Nokia, may not own even one part of the units that make up the device but licensed them from the owners of the patents. The owner of the patent, called a patentee, need not be a cell phone maker or in any manufacturing business at all. The patentee to the intermittent windshield wiper was not a car manufacturer. Instead, car manufacturers took non-exclusive licenses from him and paid him loyalties for using his invention. An exclusive license may have antitrust implications; I leave that for another day.

Patent licensing and patent litigation are the most flourishing areas of legal practice today due to the proliferation and advances in science and technology. Companies go into cross-licensing to checkmate unnecessary conflicts and compete only in those areas where they really need to. In 2004, Sony and Samsung entered into an agreement to share patents on basic technology, to speed up product development, and avoid adding to a growing number of cross-border patent disputes. The implication is that your Sony Plasma TV shares same technology as your neighbor’s Samsung!

I have been reading the World Intellectual Property Organization, (WIPO) report since 2003. I usually subject it to a search for “Tanzania”, a ritual all electronic documents that come to my desk pass through. It would have been like searching for the face of your lover in Kariakoo market, but again, thanks to technology, it took less than 3 seconds. My search for Tanzania saves me unnecessary embarrassment. I need to know where my beloved country stands before discussing such document. To appreciate what the WIPO report said about Tanzania, we need to know what it said about other countries.
The 2009 report shows that worldwide patent application filings have increased an average of 4.7 percent a year since 1995, with the highest growth experienced in North East Asian countries, notably South Korea and China. Of the 5.6 million patents in force in 2005, 90 percent were granted by 10 patent offices: the United States, Japan, Germany, South Korea, United Kingdom, France, Spain, China, Canada and the Russian Federation. Additional details include the following:

1. The largest recipients of patent filings are the patent offices of Japan, the United States, China, South Korea, and the European Patent Office. These five offices account for 77 percent of all patents filed in 2005, and account for 74 percent of all patents granted.

2. That China experienced the highest growth rate in both residential and nonresidential filings, boasting a 42.1 and 27.9 percent increase, respectively, over earlier filing rates.

3. Residents of Japan were the most frequent patent grantees worldwide, followed by residents of the United States, South Korea, Germany and France. Applicants from Japan and the United States owned 28 percent and 21 percent, respectively, of patents in force worldwide in 2005.

4. U.S. applicants continue to lead in overall PCT applications, followed by applicants from Japan and Germany.
Tanzania did not show up in Table 1: Patent Filings and Grants by Office, meaning that we have a dead patent office. However, in Table 2: Patent Filings, Grants and Patents in Force by Country and Territory of Origin, Tanzania is credited with Non-resident direct filings, one National Phase Entry, one PCT International Application, and only 2 Patents in force since 2000 !

In contrast, South Africa has 5,554 National Phase Entries, 248 non-resident filings and 2,486 patents in force. China, our satellite development partner, has 2,561 non-resident direct filings, 156 Resident Direct filings, and 59,087 patents in force. Brazil has 3,821 Resident direct filings, 2,560 non-resident direct filings, and 5,500 patents in force. United States garnered 202,776 direct resident filings, 51,921 non-resident direct filings and 1,214,556 patents in force.

If we really have scientists and engineers in Tanzania, how come they’ve not done anything to change the world like their foreign counterparts? What have all the research institutes done to positively impact the lives of Tanzanians? People all over the world are coming up with innovative ways of performing old tasks and improved seeds for bountiful harvests. The report shows that the United States and the Japanese Patent Offices respectively had more than 900,000 and 800,000 patents pending in 2005. How many Tanzanians have been issued with any utility patent from any country whatsoever since 2000?

Professor Boroffice of Nigeria was once quoted as saying, “We must contribute to the development of technology because he, who has technology, has power.” I agree with him. But nobody ever transfers power willingly. The Chinese did not send their scientist to the UK or the US to build satellites. They stole the technology by the process of reverse engineering. The professor should know what I am talking about, but I doubt whether our lawyers do. Reverse engineering is the general process of analyzing a technology specifically to ascertain how it was designed or how it operates in order to duplicate or enhance the object. Reverse engineering is illegal in some countries. Our lawyers should study our domestic laws and international treaties on the subject. We can start with products whose patents have expired and move from there.

If I may I humbly ask, are Tanzanian lawyers paying any attention to patent practice? Why are they not collaborating with Tanzanian scientists and engineers to develop a robust patent protection system? While our lawyers are enmeshed in land cases, election/chieftaincy petitions and petty politics, the legal minds of other nations are moving forward, in tandem with their inventors, leaving us behind like paralytic consumers of technology.

Finally, one conclusion to be drawn from the above facts is that Tanzanian leaders and scientists know nothing with respect to patent law in the development of science and technology. When President Jakaya Kikwete bemoaned the various problems confronting the country, attributing them to disrespect for the rule of law, he, a scientist, I believe, knows the importance of obeying natural laws. Inventions are based on strict adherence to natural laws. Obedience to law is the key to technological development. Our total disregard for laws is our bane. You cannot practice science with a crooked mind. Science abhors dishonesty!

Renewable energy: How to make an efficient sawdust stove

One of the simplest fuels for cooking and for heating the house in cold times is sawdust . . . a waste product which is usually thrown away and which, therefore, is obtainable free or at nominal cost. (True, not everybody lives conveniently near a sawmill or lumberyard, but the same objection applies to many other alternative sources of power. Not everyone has a stream running through his property to generate electricity, or keeps cattle to supply manure for methane. We must make use of whatever resources are available to us.)

Sawdust will burn properly only in a specially constructed stove, which is very simple to make and costs practically nothing. The fuel always lights with only one match in such a unit, and can be kept ablaze for long periods—six, eight or even twelve hours if desired—with absolutely no smoke, no blowing or fanning and no refueling.

Once lighted, such a stove burns until all the fuel it contains is consumed. It can then be recharged and lighted again. Such a device is ideal where steady heat is required for hours on end with no attention (to provide day-long hot water, for instance, or to keep a sickroom cosy and warm through a chill winter’s night).

To make a sawdust stove, take a large paint can, remove the top and cut a two-inch hole in the middle of the bottom. Set the container up on three legs, and the stove is ready. The only “tool” you’ll need to make your burner work is a smooth round stick or length of water pipe which will fit through the hole in the bottom of the can. It should be long enough to protrude four inches above the can’s top edge when the shaft is passed vertically through the stove and its lower end rests on the ground.

It is absolutely essential that the fuel for this stove be bone dry. If it’s slightly damp, it will smoke. . . and if it’s very damp it won’t light at all. Dry sawdust burns wonderfully well—sometimes even with a blue flame—and is entirely smokeless. It does give off some fumes, however, and the room where the stove is in use must be well ventilated.

To load the burner, insert the stick or pipe through the hole in the bottom of the can and hold the shaft straight up while you pour sawdust around it. Every now and then, as you fill the container, press the fuel down—the harder the better—to make it tight and compact. When the can is full, completely cover the top of the sawdust with a thin, even layer of sand or ashes. Then twist the pipe back and forth and carefully pull it out of the packed fuel. You’ll have a neat hole—which will act as a chimney—right through the mass.

The sawdust stove is easy to light. Just crumple a sheet of newspaper accordion-fashion and push it gently down the chimney until it protrudes at the bottom. Put a match to the lower end, and the homemade heating unit will require no further attention whatever until the fuel is completely consumed.

The powdered wood burns from the center outward, the hole gradually increasing in diameter until there is no sawdust left and the flame dies out. The rate of consumption is about an inch and a half to two inches per hour (the figure varies slightly with the quality of the fuel and how tightly it’s packed). A stove one foot in diameter will burn about six hours, and one eight inches across will operate long enough to cook a meal and produce some hot water to wash the pots and
pans.

The amount of heat produced is regulated by the depth of the container: the longer the chimney, the hotter the flame. A tall, narrow stove will become very hot for a relatively short time, a broad, squat model will give a gentler heat for a longer period and a tall, wide drum will burn both long and hot. Calculate the dimensions to suit your requirements.

The basic design can be adapted to special purposes. For example, a good sawdust-fired kitchen range can constructed in either of two ways: [1] Two or more legless drum stoves can be bricked in, with a small opening b low each to admit air and remove ashes. [2] The stove can be built brickwork alone, without drums, and two-inch round hole made through the wall into the bottom of the firebox. This second model is filled with the help of two sticks or pipes. One is first is pushed through the front opening least as far as the center of the stove and the other is held upright so that rests on the horizontal rod. Then the unit is packed with fuel and both sticks are drawn out.

The basic sawdust burner may be modified into a space heater to do laundry on a rainy day or warm a living room on a cold night. To adapt a can stove for this purpose, a second container (with its top removed) turned upside down and fitted snug onto the upper rim of the heater. This radiates warmth into the room. An opening is made in the upper chamber near the top, to receive a stovepipe which carries any fumes out through a wall or window. If desired, a hole with a removable cover could be cut in the top to make an open burner for heating a kettle.

Whether you decide to modify the basic sawdust burner I’ve described or not, I think you’ll find the device presents a most efficient means of using a common waste. I know you’ll also finds that it produces steady, reliable heat for cooking and/or warmth.

Tanzania: Ten Year BAE Systems Aviation Radar Purchase scandal that just won’t go away

THE MULTIMILLION DOLLAR SCANDAL, INVOLVING THE BRITISH FIRM AND THE SUPPLY OF AVIATION RADAR TO TANZANIA COMES BACK TO HAUNT

Investigative News Writes Leo Odera Omolo

Information emerging out of the Tanzanian capital, Dar Es Salaam says that the country is at crossroads, wondering whether to investigate afresh an international corruption case involving British arms manufacturers BAE system.

This came about after the company had allegedly admitted it was guilty of dubious financial dealings in its sale of a USD 46million Watch Air Traffic Control System to Tanzania.

BAE Systems, it was reported, admitted there were malpractices received as payment in the deal.

In its latest edition, the EASAFRICAN weekly quoted the company chairman, Mr.Dick Oliver as saying in an exclusive interview that “Under the agreement with the Serious Fraud Office {SFO}, the company will plead guilty to one charge of breach of duty to keep accounting records, in relation to payments made to a former marketing adviser in Tanzania.

“The company will pay an agreed penalty of 30 million sterling pounds {USD 46 million}, comprising of a fine to be determined by the court, and the balance as a charitable payment for the benefit of Tanzania”.

But back in Tanzania, senior officials of the Prevention and Combating of Corruption Bureau {PCCB} and the Ministry of Justice, were reported to be tight-lipped on whether to continue with fresh investigations or not.

Last week, UK’s Serious Fraud Office {SFO} allowed BAE to plead guilty in a London court to the offence of selling to Tanzania a 28 million pounds air traffic control system, and yet requesting for USD 46 million in payment.

The SFO then dropped its charges against those involved in scandal, who included Tanzanian officials Anbdrew Chenge {then the Attorney General} business tycoon Tanil K.C Somaiya of Shivacom and one Shailesh P.Vithilan.

In court, they were accused number six, eight and nine respectively. Accused number seven is not mentioned on the charge sheet.

Mr Chenge was later appointed a minister for Infrastructure Development in the President Jakaya Kikwete administration. But he resigned after SFO implicated him in the scandal, with claims alleging that he had received 1.5 million sterling pounds from BAE as “Kick Backs”.

The World Bank and the International Civil Aviation Organization –before and after the purchase of the system –said it was unnecessarily overpriced.

The PCCB investigation was however largely dependent on SFO findings, meaning the country will have to conduct its own probe.

This viewpoint is supported by the Deputy Leader of the official opposition in the National Assembly, Dr Wilbrod Slaa. And the SFO has been actively investigating the USD 39.5 million {Tshs 53.billion} contract signed in 1999 to supply a radar system to Tanzania.

The probe also relates to payments of USD 12 million to Shailesh Vithilan, BAE’s former marketing adviser based in Dar Es Salaam.

A six year investigation by SFO identified key roles played in the radar deal by Mr.Chenge, the former AG, and Dr. Idris Rashid, the then Bank of Tanzania governor.

PCCB public Relations Officer, Doreen Kapwani, was quoted last week as saying that they were yet to issue a comprehensive statement on the matter.

Tanzania Minister for Justice, Mathias Chikawe, also declined to offer any comment. But by pleading guilty under section 221 of the companies Act,1985,BAE will not face an embarrassing court case.

Last month, Uganda civil aviation authorities demanded payment back for a dummy radar, which was purchase before the summit of the Commonwealth Head of States and Government {CHOGM] in November 2007, which has since then ceased to operate.

Young Tanzanians: Our Role in Tanzania transformation

Tanzanian youth in Society transformation

There is no doubt that almost all Tanzanians want change, and the mood for change is evident from small villages to big cities where poverty, disease, lack of social infrastructure and most significantly lack of hope is everyday reality for millions of Tanzanians. 21st century Tanzania seems to be a shadow of its glorious past where recruiters from governmental establishments transverse university campuses in search of prospective employees, even before they graduated. Today, the story is different as our youth, even those who have reached the highest academic echelon, are hopeless, helpless, jobless and at times homeless.

The incandescence and pride of being a Tanzanian youth many years ago is somehow obliterated by the perpetuation of evils by our very own elders, some of whom have extolled themselves as elder statesmen. Young men and women across Tanzania have been bequeathed with a sense of social, political and economic insecurity by these same people, and many of us have been indoctrinated into a mirage of hope in an attempt to fight, sometimes violently, the selfish cause of the political elites at the polling booths and beyond. Our unquestionable allegiance to these same elders that have destroyed our land in itself raises concern that change in the political landscape of Tanzania is far from remote. There is no doubt that there are many Tanzanians at home and in the diaspora who desperately yearn for change.

Even in the face of enormous difficulties that confront the youth, we can collectively mobilise ourselves as agents of change and help build institutions of democracy devoid of generational corruption that Transparency International and the entire international community have come to associate with the mention of our country. We need to mobilise ourselves beyond the virtual platform of Wanabidii.net . We need to transform our virtual ideas into sustainable reality. Our problems in Tanzania will not be solved by secession; our problems in Tanzania will not be solved by waving spears and arrows; our problem in Tanzania can only be solved when Tanzanians at all social strata embrace the humanity of one another; when Tanzanians embrace the spirit of “Live and let live”; the true spirit of egalitarianism. Our problems could be solved through non-violent but persuasive discussions, objective engagement and sustainable diplomacy.

The youth have enormous responsibility in chatting a new cause for Tanzania. In my contacts within and outside Tanzania, there seem to be a growing and continual push for a national youth-initiated agenda and a youth-led coalition that would push for the renaissance that we all aspire to see in our country. There is by all account hundreds of youth-led non-governmental organisations (NGO’s) dotted across the country with fragmented and sometimes easily diluted ambition to single-handedly bring social and economic change. There is no doubt that one cannot readily discount the contributions of many of these NGO’s, but the reality is that meaningful progress would not be made in transforming the socio-economic and political landscape of Tanzania except these youth organisations come together and develop a strategic national agenda and priority areas that focus on improving the lot of ordinary Tanzanians, while building institutions that have democratic legitimacy; institutions that are sustainable for the sake of posterity. There is a growing need for a database of functional youth-led NGO’s, student organisations and other youth organisations to be developed. The aim is to get these NGO’s and organisations actively engaged in the development of a non-partisan national youth conference with the ultimate hope of developing goals, initiatives and strategies aimed at improving the image of our country and securing a future for Tanzanians of today and those unborn.

The current situation in Tanzania also challenges the media both print and electronic. The current situation in Tanzania where the media is biased and unwilling to cross muddy waters pinpoint the failures of the media, and highlights the lack of journalistic integrity in contemporary Tanzania. Our media houses and journalists have failed us as gatekeepers and agents of social justice. There is no doubt that the Tanzanian media is recovering from the fear of many years of oppression by previous Leaders in which legitimate media houses were closed, journalists perceived as traitors to national security arrested and imprisoned and freedom of the press stifled. Our current political dispensation promises that the media will not be harassed or subdued, so the onus is on our youthful journalists to engross themselves in a more investigative journalism poised at exposing government officials whose nefarious acts of corruption and other social and economic injustices today present a bleak future for Tanzanians, born and unborn.

The call for an alliance of all well-meaning youth-led organisations in Tanzania is growing. Together we can achieve more than we can individually. Our goals and aspirations for Tanzania share a common background and rooted in the ideals of peace, progress and prosperity, but our ideas are challenged by the fragmentation of our agenda, coupled with limited human and material resources.

We need to help build a Tanzania where poverty and despair for the majority of our population are challenged with the resources we have; we need to help build a society where our youth are not constantly harassed on arrival at foreign countries because they are by default deemed criminals or flight risks; we need to help build the generation that will build our nation. Our youth could help build sustainable democracy and democratic institutions. The Tanzanian youth could foster the election of individuals with democratic legitimacy and shy away from short-term gains and long-term losses involved in supporting individuals with questionable character.

For most of us, our role models are our parents and elders, but unfortunately this generation has for the most part failed us, meaning we have to develop our own model of problem-solving and critical analysis of the contemporary reality facing the youth. We cannot remain complacent of the reality of a typical Tanzanian youth who is faced with the quagmire of whether to eat, cloth or find adequate housing. In the land of plenty, in the land blessed with enormous human and material resources, the youth should not be faced with the challenge of sourcing clean water, health care, education and non-existent employment opportunity. The challenges facing the Tanzanian youth and indeed Tanzania is growing, we need to begin to mobilise ourselves and develop a unified voice that could question the idea of business as usual among our elitist politicians. We need to fight for a safer society that will discourage brain drain and help build sustainable economy and democracy. It is by challenging the status quo that women today are able to vote across many countries; it is by challenging the status quo that racial segregation was ended in America, and it is only by challenging the status quo that change can come to Tanzania. By the youth coming together across Tanzania with a unified but non-violent voice, change could be brought to our beloved country Tanzania, and posterity could be assured of a better future

Rwanda launches first Wireless Broadband “hot spot” capital city in Africa

Subject: Kigali to become a wireless City

Kigali will soon go wireless after the government launched a $7.66 million wireless broadband (WiBro) facility that is set to make it the first “hot spot” capital city in Africa.

The service will go commercial in three months.

The wireless Internet facility was built by Korea Telecom, South Korea’s
largest fixed-line telephone operator and second-largest mobile carrier.

Korea Telecom clinched the $7.66 million deal in 2007 from the Rwandan
government to build an infrastructure for the WiBro technology-based
network.

“The launch marks the first entry of WiBro technology into Africa.

Along with a number of similar projects in Africa, the South Korean company is also undertaking a $40 million project that commenced in 2008 to provide a network for Internet access in Rwanda called the Kigali Metropolitan Network.

The Kigali Metropolitan Network (KMN), which is laid on a fibre optic loop, is a large computer network that spans a metropolitan area.

It also provides Internet connectivity for local area networks in a
metropolitan region, and connects them to wider area networks like the
Internet.

MAMBO YA IT SUPPORT TUMETOKA MBALI

Kuna wakati tuliwahi kutembelea na rundo la CDs bila kusahau Floppy Discs ambazo ndani yake kuna programu mbalimbali za kutumia Kwenye komputa au ni programu zinazotumika kusaidia katika kuifanya HDD ionekane wakati unapotaka kuinstall Windows wakati huo ni windows 9x .

Ukitaka kuinstall windows kwa mfano ulihitaji programu ya kuboot ambayo ilipatikana Kwenye floppydisc hivi bootable floopydisk ziliweza kutengenezwa kutumia Komputa yenyewe ukishamaliza kuinstall au kutumia nyingine ambayo imewahi kuwa installed na wale wenye kuweza kutumia mtandao waliweza kuzishusha kutumia mtandao .

Hapo bila kusahau cd iliyokuwa na operating system kama ni windows 9x au chini yake au aina nyingine ya operating system lakini nitaongelea zaidi windows ndio maana natumia 9x wakati mimi naanza masuala haya nilikuta windows 9x , kwahiyo bila bootable floppy disk huwezi kutumia cd ya windows 9x kwa ajili ya kuinstall hata windows NT na Windows Me na 2000

Baada ya kuinstall windows ulihitaji drivers za vitu mbalimbali Kwenye komputa hiyo kama modem wakati huo mtandao haukupanuka sana ulihitaji modem kwa lazima kwahiyo driver zake lazima uwe nazo nakumbuka tulitakiwa kuwa na cd mbalimbali zenye driver za modem ili ikitokea tu uweze kutumia cd hizo .

Muda ulibadilika sasa ikaja windows 98 sp2 ambayo ilikuwa inauwezo wa kuboot yenyewe bila kutumia msaada wa floopydisk na hapa ndio mabadiliko makubwa yalipoanzia , kuanzia hapo vitu na mambo hayajawahi kuwa sawa tena kama ilivyo mwanzo .

Sasa tuna mpaka dvd unazoweza kuhifadhi operating systems kuanzia windows vista mpaka windows 7 na programu nyingine nyingi nyingi sana tatizo na drivers hakuna sana kwa sababu kampuni zote zinazotengeneza bidhaa hizi zinaweka driver za bidhaa zao bure Kwenye tovuti zao kwa ajili ya kuchukuwa na kwenda kutumia

Kuna hata baadhi ya programu kama driver magician ambayo inauwezo wa kutafuta driver stahili za komputa yako na kukupa linki ya moja kwa moja kwenda katika wavuti unaoweza kupata driver hiyo ukiwa na mtandao unaweza kuzishusha na kuzitumia hapo hapo bila shida yoyote .

Hata mtandao umesambaa sana na kutokana na kuunganishwa na mkonga wa mawasiliano uliopita baharini hakuna tena hadithi za drivers na hata programu zingine ndogo ndogo ukiongelea drivers wengi wanaweza kukushangaa kwa sababu zinapatikana kwa urahisi zaidi kuliko wakati wowote ule .

Enzi hizo kulikuwa na watu wachache sana wanaofanya shuguli za ICT haswa masuala ya ufundi pamoja na vifaa vya kufanyia kazi kuanzia programu mpaka aina nyingine ya vifaa vidogo vidogo na hata wakati mwingine vifaa hivyo vilikuwa ni bei kubwa kuweza kuvipata na kutumia na zaidi ni kwa wataalamu hawa kulipwa hela kidogo kuliko ilivyosasa hivi fani hii ilivyopanuka na kuwa na vitengo mbalimbali pamoja na kampuni nyingi kuanzishwa haswa za kimataifa .

Hii ni pamoja na kuwa na kampuni nyingi zaidi zinazotoa kwa mfano huduma ya mtandao kwa wateja , makampuni ya simu ambayo yanahuduma mbalimbali na nyingi zinazohitaji watu wa ICT Kwenye kushugulika nazo pamoja na kuwa na chombo cha kusimamia masuala mengi ya mawasiliano nchini hii imesaidia sana katika kuweka mambo mengi sawa Kwenye suala zima la mawasiliano .

Ukija Kwenye masuala ya programu na kadhalika enzi hizo kulikuwa na programu chache sana na ambazo hazikuhitaji mfano memory kubwa Kwenye komputa katika utendaji hata nafasi kubwa ya kuhifadhi Kwenye komputa kwahiyo mambo mengi yaliweza kufanyika .

Tukija Kwenye masuala ya programu za ulinzi kama antivirus na firewalls pamoja na spyware enzi hizo ni antivirus zilizokuwa na soko kubwa sana , firewalls hazikuhitajika sana haswa kwa watu ambao walikuwa hawajaunganishwa Kwenye mtandao

Hizi antivirus zilikuwa nyingi na uwezo wa kufanya kazi 3 tu nayo ni kuscan virus , kuondoa na kulinda tu , enzi hizo hakukuwa na matishio kama spyware na aina nyingine ya matishio kwa njia ya mtandao nakumbuka nilitumia sana Norton antivirus na updates zake niliweza kuhifadhi Kwenye floppydisk au zippdrive wakati huo ilikuwa ni mb chache tu .

Wale waliokuwa wanatumia bidhaa za mcafee wanakumbuka jinsi ilivyokuwa rahisi kuweka updates Kwenye floppydisk lakini ilivyokuwa kazi kuhifadhi stinger Kwenye floppy hizo hizo kwa ajili ya kuscan virus na kuondoa Kwenye kompyuta wakati huo jina lake lilikuwa ni hilohilo stinger na ilikuwa maarufu sana kwa sasa stinger imebadilishwa jina kutokana na kutengenezwa virus zilizokuwa na uwezo wa kuharibu programu hiyo kwa sasa sijui nani anatumia stinger toka mwezi wa 10 mwaka jana sijaona updates zake .

Hivi ninavyoandika sasa hivi update ya mcafee virus scan 8.7 imekuwa na ukubwa wa zaidi ya mb 110 na kila siku ukubwa wake unazidi kuongezeka kwahiyo kuna vifaa zaidi ya kuweza kuhifadhi update hii unaweza kuamua kuichoma Kwenye cd au kuhifadhi Kwenye flashdisk na aina nyingine ya vichomeka ambavyo ni vikubwa zaidi vya kuhifadhi vitu hivyo .

Unapohifadhi Kwenye flashdisk napo kunaweza kuwa na madhara yake kama unaenda kuitumia Kwenye komputa yenye virus , virus hao wanaweza kuathiri update hiyo kwahiyo ni bora kuhifadhi Kwenye cd ambayo virus haina uwezo wa kujiandika Kwenye cd hiyo .

Wakati huo pia hakukuwa na shida kubwa kwenye masuala ya leseni za baadhi ya programu pamoja na operating system kwa sasa unahitaji sana leseni ambayo ni yako kwa ajili ya kila programu iliyoko Kwenye komputa yako unayotumia hili ni lazima hata zile programu za bure zote zina leseni yake utaona wakati unaingiza imendikwa leseni yake na ni lazima kukubaliana na maazimio yaliyoandikwa kwenye leseni hiyo .
