Water is the most widely occurring substance in the world. Over 72% of the earth’s surface is covered by water. This means that the bodies if water were evenly distributed, it would have covered the globe. Even the soil and rocks of the earth’s crust hold water in chemical combination with different mineral substances, so much that most of the land areas of the earth would be submerged if water were suddenly returned to the ocean. Yet so far as human beings are concerned, water is unfortunately unevenly distributed. In some regions, it is in abundant and properly utilized, while in some others, it is wasted and polluted, and in the remaining regions, it is scarce or completely lacking. This paper examines water scarcity in Nigeria, water needs and demands, water resources planning, water supply and human health, factors associated with scarcity of water in Nigeria and the way forward.

The new challenge posed by the computer age is that of organisations and individuals having cloud presence. The major form of cloud presence that is vital to success of organisations and individuals is having hosted site that can be accessed from anywhere through internet connection. Resulting from this trend, organisations and individuals give a rush to own website! Hundreds of websites are hosted on the cloud on weekly basis. However, just like having a new estate is having its challenges; same applies to hosted sites on the cloud. Online threats of different forms are found on the internet and these threats can cause serious harm to newly hosted sites or even sites that are old. Many sites do not give their owners the needed satisfaction required, resulting from online threats the sites are facing. While some sites are even hijacked from its rightful owners and taken by hackers. This research intends to study common online threats sites may face and the negative consequences that may result from effects of these threats on hosted sites. The research will make an attempt to suggest measures on how these threats can be remedied or prevented. In the course of conducting this research two web servers of Gwani Software Limited are studied through WHM panel the two web servers addresses are www.gwaniwebhost.com and www.gwaniwebhost.com.ng

The heat stress and time consuming experience in the frying of groundnut in North-East Nigeria gives a great discomfort to the processors. The effects of this risk, among other inherent risks, on the workers are very hazardous and posed a serious health challenge to their lives. When excessive, this can cause heat stroke, a condition that can either threaten their lives or cause dire consequences. In order to alleviate this problem, an induction heater suitable for the frying of groundnut with almost zero heat stress and less time consuming is proposed. This study used the principle of soft switching in design and construction of the induction heater. It is achieved by addition of resonant elements to a pulse width modulated inverter to provide soft switching. The resonant circuit brings the current to zero in order to provide zero switching for the inverter switch. This inverter provides soft commutation and higher efficiency as compared to the hard switching PWM inverter and it therefore alleviates the problems associated with it. The proposed resonant inverter system configuration has the significant advantage of being capable of suppressing the irritating acoustic noise, lowered switching losses, reduction in electrical dynamic stresses, considerable reduction of EMI and increase the efficiency. Various samples of groundnuts were collected and dried using the induction heater and other types of heaters available in the market from different parts of the North Eastern State of Nigeria. It was found that the proposed inverter performed better in terms of the efficiency, safety and output power.

Weaning food was formulated from malted pearlmillet (pennisetum glaucum) and bambara groundnut (Vandozea L. Theuares). The malted millet flour was obtained by steeping the grain followed by germinating, drying, toasting, grinding and sieving. The bambara groundnut flour was obtained by cleaning whole sound seeds, soaking, dehulling drying, milling and sieving. Products were obtained by mixing the flours in the ratio of (A) 90:10, B (80:20); (70:30); D (60:40); E(50:50). A control sample (Cerelac) F was used as reference sample. Proximate composition of the various products showed that moisture ranged from 6.01 to 7.08(%); Protein ranged from 11.58 to 25.40. Viscosities of the products decrease with increased amount of bambara groundnut from 4.6 x10-2NSM-2 to 3.8×10-2NSM-2. Sensory evaluation of the products showed that there was no signification difference (P£0.05) among the products in terms of Colour, taste and texture. However samples B and C compared favourably well with the control sample in terms of general acceptability.

The response of Moringa oleifera (lam) to four different levels of cow dung manure was assessed. The cow dung manure constituted 25%, 50%, 75% and 0% of the total potted mixture in the four replications. Randomised complete block design was used for the experiment. Three parameters (height, girth and number of leaves) were measured and recorded in each of the four replications after every seven days for a period of 56 days. Under the height parameter 50% level of cow dung has the highest mean of 26.8cm, then 25.6cm at 25% , 24.7cm at 75% and 13.8 cm at 0% level. For girth the thickest mean of 1.4cm was observed at 50% level, followed by 25% and 75% each with 1.3cm. The thinnest mean girth was recorded at 0%. The trend was however the same for number of leaves. The results indicated that optimum initial yield in the nursery is obtained when cow dung constitute 50% of the potted mixture. These findings have indicated the great potentials in producing vigorous and viable moringa seedling using cow dung manure.
