 The sun has been a wonder from the time of the earliest civilisations.
From religion to art, dance, science and astronomy, the sun has played a prominent role in human history. Africa is uniquely placed to harness sun energy, Melford Ita, urges. Solar (or photovoltaic (PV)) effect converts sunlight into electric energy. The conversion can be aided by batteries, which collect current from solar modules and store the incoming electric energy as chemical energy – the Charge. When needed, the chemical energy can be given off as electric energy – the Discharge. Energy is never lost but stored in the battery for use at night or as the case on cloudy days. Depending on battery type deployed, during the charging process a small amount of water is released as hydrogen and oxygen. Maintenance involves no more than monitoring the electrolyte level. However, maintenance-free batteries are also available. Batteries serve two functions; firstly, to provide short-term high power output, which can be a factor greater than module output – for example when starting a refrigerator. Secondly, to disengage module circuit from the consumer circuit, i.e. when more current is produced in the solar module(s) than actually needed, this potential energy is not lost but stored for later use. From 12-14 June 2008, Bayern’s state capital – Munich – Germany hosted the world’s largest solar technology trade fair; an annual meeting place for everyone in the international solar Industry. Featuring photovoltaic, solar thermal technology and solar architecture, the fair presented a unique insight into what manufacturers, suppliers, wholesalers and service providers within the industry in Germany and the global solar markets have to offer. Over 40,000 (31,000 last year) visitors attended the three-day event. More than 1,000 (638 last year) exhibitors presented their products and services across 76,000 square metres of exhibitor floor space. Around 40% of the exhibitors were foreign companies from China, Italy, South Korea, Taiwan and the United States.

Do you rely on tea, coffee, cola drink or kola nut to kick or jump-start your day? Are you drinking more than four cups a day? Yes? Then, you may be addicted. Caffeine is a drug (it is classified as a restricted substance by the international Olympic Committee). Regular consumption brings about tolerance to its effects, and over time you need to consume more and more to get the same buzz. Overdose is possible but rare. It is, however, safe up to approximately 250mg a day (about 160 cups of coffee).

It is not just people with diabetes who need to think about blood sugar. Somewhere between normal glucose levels and the high levels of full-blown diabetes is a potentially dangerous middle ground where glucose levels are abnormally high, and can set you up for many diseases including heart disease, diabetes itself, and possibly cancer. The discovery of white sugar has led to the invention of juices, drinks, and foods that flood our bodies with abnormally high levels of sugar every day, and compromise the natural processes of maintenance, growth, and development in ways that our bodies were never designed to handle. Diabetes is a syndrome of disordered metabolism, usually due to a combination of hereditary and environmental causes, resulting in abnormally high blood sugar levels (hyperglycemia). Blood glucose levels are controlled by a complex interaction of multiple chemicals and hormones in the body, including the hormone insulin. Diabetes mellitus efers to the group of diseases that lead to high blood glucose levels due to defects in either insulin secretion or insulin action.

How far can an entrepreneur go without being skilled? You will always negotiate with associates, workers, to win contracts, for peace at home and the workplace. Negotiating a win-win solution for conflicting parties is inevitable. Most meetings and conversations end up with negotiation, without planning for a meeting of such. It is a part of our daily lives. To negotiate means to bargain, confer and discuss with the aim of reaching an agreement and achieving a fair, mutually beneficial conclusion. Negotiation is successful when both parties win; a win-win consensus.

“Toyin, watch the way you spend in the next few months, save more, spend less except on necessities”. This was the beginning of a long conversation between my sister and I ” There is no doubt that there are financial constraints from the length to the breath of Nigeria. It is a wave from the recession in the west, or did ours begin long before that? This is a question to ponder. Spending less surely means more savings and a more secure financial future. Extravagance is almost a thing of the past for most households. Avoid credit purchases, you are only spending from your future, cut capital expenditure for a while except you are a ‘guru’ at making predictions, cut some habits: Eating out, expensive apparel, carry less cash, travel in the class of service your afford, consider the necessity or importance of your trips before you embark on your journey.
