Scirj-Pectographic Study of Carbonate Sediments around Yewa River, Eastern Dahomey Basin, South West

Limestone is the major component of carbonate sediments, and is usually deposited with the remains of skeletal fragments or marine organisms such as plants and microscopic animals as a result of both organic and inorganic processes. The associated minerals are:calcite, aragonite and dolomite minerals. The major ways of classification of limestone are based on its mineralogies, (allochems, cements, matrix) and texture (grain stone, packstone, mudstone, wackestone and boundstone). The topographic maps of Idogo NE, sheet 273NW of the study area includes adjoining communities around the North East and North West of River Igbin and south east of River Ogun, south of River yewa which drains in a sub dendiritic and dendiritic pattern and flows into the Yewa lagoon were studied and divided into grids of 500m intervals.

Scirj-Enhancement of Photorefractive Two-Beam Coupling in KNbO3

A theoretical study has been done to investigate the significant enhancement of the photorefractive and photovoltaic effects of a new co-doped potassium niobate crystal (KNbO3: Fe: Ag) as compared to the result obtained for singly doped potassium niobate crystals. The co-doped Ag impurity enters the K site, rather than the typical Nb site, thus changing the local field in the lattice. It is believed that Fe perturbed by the Ag in the K site is responsible for an enhancement of the linear absorption and photocurrent, as well as for the probable increase in the effective trap density. An enhanced trap density is likely the cause of the increased photorefractive counter-propagating two-beam coupling efficiency.

Scirj-Anti-mycobacterium activity and Bioassay guided fractionation of the leave extract of Ximenia

This work was aimed at providing preliminary findings that unraveled the promising potential of X. americana for the management of Mycobacterium bovis. The study tried to assess the anti-mycobacterial activity of Ximenia americana using the leave extract after extracting with methanol for 48 hours and the extract subjected to serial solvent partitioning with hexane, chloroform and n-butanol. The various solvent fractions obtained from the partitioning were screened against Mycobacterium bovis and the result showed hexane, chloroform and n-butanol extracts to inhibit the growth of the bacteria with a minimum concentration (MIC) of 3200 µg/ml, 1800 µg/ml and 3500 µg/ml respectively. The activity of the chloroform extract was found to be higher than the hexane and n-butanol as such Bio-assay guided fractionation of the chloroform extract was further carried out using column chromatography and nine fractions were obtained.

Mckenzie Corp Addressing Alkalinity & Feedwater Pretreatment

All boilers, regardless of their design, require some degree of feedwater pretreatment. This pretreatment process addresses the three specific areas: water hardness, Total dissolved solids and alkalinity levels. Since we discussed water hardness and TDS in previous boiler tips we felt is was time to address alkalinity. Acceptable Levels of Alkalinity Alkalinity, like hardness and TDS, is expressed as parts per million (ppm). The acceptable level of alkalinity in a boiler depends largely upon the pressure that the boiler will be operating at. In a low pressure boiler, this level should not exceed 700 ppm. If the alkalinity level exceeds 700 ppm it may result in a breakdown of the bicarbonate producing carbonate and liberate free carbon dioxide with the steam. This presence of carbon dioxide will corrode steam and return lines. THE MAXIMUM ALLOWABLE CONCENTRATION OF ALKALINITY WITHIN A LOW PRESSURE BOILER IS 700 PPM.

Scavengers working on dumpsite are often engagedin various health risk behaviour as a result of working conditions with solid waste. The study examines personality traits, self-efficacy and health anxiety as predictors ofhealth risk behaviouramong scavengers. For personality traits, widely accepted Big Five was utilized as indicators; the Big Five dimensions were openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. Personal safety, violence related behaviour, suicide and sexual behaviour were utilized for health risk behaviour.

scirj-E-Payment System Adoption in Nigerian Ministries, Departments and Agencies (MDAs) Gains and Ch

ICT is a fast developing technology; its application typically involves the introduction or enhancement of systems or technology to meet a particular business need. An example of such application is the e-Payment system, a subset of e-Government that enables us to perform financial transactions electronically. A survey was conducted in the federal government of Nigeria’s Ministries, Departments and Agencies (MDAs) to examine the gains and challenges of the e-Payment system commenced on January 1st, 2009. Non-parametric tests were used to establish the rank orders of gains from e-Payment and the challenges, based on median values for each variable, as well as the number of valid answers. The result revealed the most appreciated gains and most encountered challenges of the new system. The t-Test result for the gains of e-Payment shows that the mean number of positive response was significantly different (P < 0.01) from that of the negative response for each of the gains. Also, the t-Test

scirj-Proximate and Phytochemical Composition of Leaves of Ceiba pentandra, Manihot esculentus and A

The leaves of Ceiba pentandra (Java), Manihot esculentus (Cassava) and Abelmoschus esculentus (Okra) are consumed as vegetables in Southwestern Nigeria. The proximate and phytochemical composition of these leaves were investigated using standard procedures. Powdered dried leaves of Java, Cassava and Okra were analysed for ash, moisture, fat, fibre, protein, carbohydrate, tannins, flavonoids, phenols and ascorbic acid composition. The percentage composition result values for ash, moisture, fat, fibre, protein and carbohydrate in the leaves ranged from 15.00% - 6.30%, 0.15% - 4.85%, 9.60% - 8.40%, 25.44% - 17.55%, 21.16% - 8.65% and 41.25% - 32.65% respectively. Tannins, flavonoids and phenols composition values ranges were 8.98% - 0.81%, 4.71% - 0.12% and 0.07% - 0.03% respectively while ascorbic acid content ranged from 3.16mg/100g to 2.84mg/100g.
