Phytochemicals are naturally occurring organic compounds present in all parts of plants, which together with nutrients and fibres provide protection to human being against diseases. In this research work, extracts of VernoniaAmygdalina leaves were prepared in n-hexane, petroleum ether, diethyl ether, acetone, chloroform, ethanol, and water using cold maceration technique and the extracts obtained were screened qualitatively for some secondary metabolites. Some macro elements (Na, K, Ca, Mg, P), which are essential for maintaining human health, were also determined quantitatively in the leaves. Findings revealed that alkaloids, flavonoids, steroids, terpenoids, phenols, saponins tannins and cardiac glycosides were present in the leaf extracts, depending on the solvent used for the extraction. Findings also showed that 0.616% Na, 0.274% K, 0.004 % Ca, 0.059% Mg and 0.800% P were present in the leaves of VernoniaAmygdalina. This research concludes that VernoniaAmygdalina leaves possess some vital phytochemicals that can be used medicinally and essential macro elements that are needed for good healthy living. The study thus provides further evidence on the traditional usage of this plant extract in treating diseases.

Beacons are small devices that broadcast a Bluetooth smart radio signal to trigger alerts or messages on consumer phones. The next version of GPS. Instead of using satellites to triangulate your position as GPS does, beacons transmit a low energy signal to provide location. Beacons are compatible with smart phones globally and nearly all i-phones and android v4.3. It makes sense for retailers to open up their beacons so that outside apps can use them to send alerts and notifications to their users. Beacons can help retailers attract users to their apps. The transmitters use Bluetooth wireless technology to sense your exact location. That’s not possible with GPS, which don’t well indoors and aren’t good at distinguishing between locations that are just a few feet apart.

Objectives: To develop the technology of objective diagnosis, treatment and prevention of PTSD in hybrid war syndrome. Conduct a pilot study of searching potential biological markers for PTSD. Methods: We systematized data on different syndromes based on the methods of induction and deduction, comparative system analysis and analogies: Vietnam War Syndrome, Afghan War Syndrome, Chechen Syndrome, Persian Gulf Syndrome. The authors also investigated the conditions of occurrence and described the mechanisms of formation the hybrid war syndrome. As an important part of developing and realisation the technology of objective diagnosis, treatment and prevention of PTSD we conducted ophthalmological study, aimed to find objective biological markers of PTSD. Results. We have developed a version of the technology of objective diagnosis, treatment and prevention of PTSD in hybrid war syndrome. The pilot study of ophthalmological PTSD markers have shown specific peculiarities in ocular physiology (eye movements, accommodation, convergence and pupil size) in persons with PTSD distinguished from the ones in healthy persons. A kind of correlation of the eye tracker data with the polygraph data has been established. Detailed data of biological ophthalmological markers we plan to present in our subsequent articles. Conclusions: The technology of objective diagnosis, treatment and prevention of PTSD in hybrid war syndrome is proposed. The technology is based on a comprehensive psychological and physical examination. It includes: 1. Establishment of possible etiological factors affecting the PTSD formation in hybrid war syndrome. 2. Detection. Comprehensive assessment and diagnostic algorithms (objective medical diagnostic procedures, objective latent control system for psychological assessment). The pilot study of ophthalmological objective PTSD markers have shown specific peculiarities in ocular physiology in persons with PTSD distinguished from the ones in healthy persons. 3. Differential treatment approach, which is based on various therapy strategies depending on the established etiological factors. 4. Prevention. "Supportive" techniques, based on “Individual chart” creation in order to identify possible risks, to track the dynamics in physiological and mental sphere before, during and after being in hybrid war.

Water hyacinth (Eichhornia crassipes) in Lake Victoria has caused water loss through evapotranspiration, provided a breeding ground for mosquitoes and interfered with fishing and navigation. The weed contains macronutrients such as nitrogen (2.5%), phosphorus (1.0%) and potassium(5.3%) which can be made available to plants by using earthworms to convert the plants into compost. The worm cast and vermicompost obtained is a better source of organic manure than other aerobically or anaerobically degraded compost and has a lower environmental impact than chemical fertilizers. This study investigated the vermicomposting of water hyacinth by the fast-growing composting worm Perionyx excavatus and determined the concentrations of macronutrients. It was found that the vermicompost contained 47% more nitrogen, 60% more phosphorus and 40% more potassium than compost produced without worms. This suggests that vermiculture could be a means of reducing water hyacinth in Lake Victoria or other water bodies while producing a valuable agricultural product.

This paper explains the modeling, designing and implementation of control logic using PID controller over step-up DC-DC converter. Mainly this paper proposed for buck converter should be operated at a particular switching frequency. It can be done by considering on time and off time of the switching period separately. This modeling of converter is useful while designing the digital feedback controller system. This design gives the reliable converter dynamic operation. In this paper a PID controller architecture is designed and this design is based on the loop shaping of the proposed frequency domain transfer function. By using this variable frequency method smooth output voltage regulation and dynamic performance is achieved.

Prices of agricultural commodities have been increasing considerably year after year. This upward trend in agricultural prices captured the world’s attention as a new food crisis was emerging. The aim of this paper is to use time series equations to forecast the prices of agricultural commodities, since price is one of the factors that can determine food security in any country. Data were collected on monthly basis for the prices of five agricultural commodities for the period of nine years (2008-2016). The commodities include local rice, cassava flour, Red maize, White beans and Red guinea corn (measured in a bowl used for measuring things in the northern part of Nigeria called mudu). The models formulated for the selected commodities were used to forecast the prices for these commodities in the future from 2017 to 2030. The results showed that the prices of the commodities will keep increasing if proper agricultural policies are not put in place which will help to increase the yield of these commodities which will in turn reduce its prices. It is only when such is achieved that Nigeria as a nation can boast of food security.

In the present paper, a new method is proposed for the spectrophotometric determination of chromium (III). The ligand; 6-[(E)-(1, 5-dimethyl-3-oxo-2-penyl-2, 3-dihydro-1H-pyrazol-4-yl)diazenyl]-1H-indole-2,3-dione was synthesized by coupling diazotized 1-phenyl-2,3-dimethyl-4-aminopyrazole-5-one and 1H-indole-2,3-dione. It formed coloured complex with Cr (III). The ligand and complex were characterized via UV, IR and NMR spectroscopy. The analytical data show that Cr(III) formed complex, with 2:1 metal-ligand stoichiometry when reacted with the ligand respectively. Cr(III) was determined spectrophotometrically by measuring the absorbance at 446.4 nm. Beer’s law was valid between 0.15-1.18 ppm, with calibration and analytical sensitivities of 0.059 and 59.00 ppm respectively. Very few elements were found to interfere in the method. The method is quite simple and useful; its applicability has been tested by the analysis of solder, steel and brass.
