CONSTRUCTION AND CALIBRATION OF A LINEAR VARIABLE DIFFERENTIAL TRANSFORMER (LVDT)
200%;font-family:" times="" new="" roman","serif""="">ABSTRACTA Linear Variable Differential Transformer (LVDT) was constructed having a primary mso-bidi-font-size:14.0pt;font-family:" times="" new="" roman","serif""="">winding of 245 turns and two secondary windings of 100 turns each. The devicewas calibrated with a graduated cylindrical rod. The graduated rod wheninserted between the hollow tube which has the windings gave output voltages of±0.046V, ±0.51V, ±0.088V, ±0.155V, ±0.2...
Comparative Studies on The Bacteria Associated With Hands of School Pupils’ in Kaduna South Local Government
ABSTRACTThis study reviewed the importance of hand washing and health benefits derived from the practice and also highlighted the consequences of not observing strict hand washing practice. Swabs from primary school pupils showed cfu mean total viable count of 1.60 x 104, 1.50 x 104, 1.60 x 104 and 1.7 x 104 across the four schools. Salmonella spp., Staphylococcus spp. and E. coli were the most sensitive microbes to the antibiotics used while Ciprofloxacin and Gentamicin were active across th...
Cultivation of Plasmodium Falciparum And Antiplasmodia Screening of Methanol Extract of Ocimum Basilicum (Scent Leaf)
ABSTRACTThe methanol extract of Ocimum basilicum (Scent leaf) was greenish in colour and increases in concentration through evaporation process which turns the extract to thick and dark green colouration. The percentage parasitaemia growth increases consecutively for seven (7) days with 7th day result having the highest parasite growth of 18.73%. The antimalarial activity of methanol extract of Ocimum basilicum conducted at six (6) different concentration (µg/ml) value shows that the highest...
Determination Of Heavy Metals In Some Cosmetic Products Commonly Used Among Students Of Kaduna Polytechnic
ABSTRACTThe toxicity of heavy metals to humans as a result of long term exposure to pollutants consumer products such as cosmetics and other pollutants has been established. In this study, the levels of heavy metals in different cosmetic products commonly used among Kaduna Polytechnic students were assessed. The cosmetics were analyzed for heavy metals (chromium, copper, nickel and lead) using Atomic Absorption Spectrophotometer (AAS) after digestion with concentrated HNO3 and HCl acid...
Synthesis, Characterization And Antibacterial Properties Of Nickel (Ii) Amine Malonate And Nickel (Ii) Amine Tartarate
ABSTRACTNickel amine carboxylate complexes were synthesized by reacting Ni(ii)chloride with ammonia, malonic and tartaric acid, which formed Nickel amine malonate and Nickel amine tartarate of blue and green crystal and the percentage yield are of both complexes are 62.65% and 62.83% respectively. The decomposition temperatures were 218o C and 203oC with percentage moisture content of 8.0% and 21.50%. The carboxylic acids and the synthesized complexes were tested for antibac...
DISTRIBUTION OF ABO, Rh (RHESUS) BLOOD GROUPING AND HEPATITIS B AMONG BLOOD DONORS WITH NATIONAL BLOOD TRANSFUSION SERVICE KADUNA
ABSTRACTABO and Rh blood group systems are of major clinical significance amongst the thirty (30) human blood group system. The Distribution of ABO, Rh blood grouping and hepatitis B virus among blood donors with National Blood Transfusion Service, Kaduna was carried out. Two hundred voluntary blood donors (200) were used. Questionnaire was used to obtain the respondents’ bio-demographic data. Microplate technique was used for ABO and Rh blood grouping tests and ELISA kit (Monolisa HBsAg UL...
Bacteriological Quality Of Some Selected Bagged Milk Sold In Markets Within Kano Metropololis
ABSTRACTMilk has been known to be highly nutritive ad thus a good medium for bacteria growth and vehicles for transmission of food borne infection. A total of 16 samples of different brands of bagged milk obtained from some selected markets within Kaduna metropolis were analyzed for the occurrence of bacteria using pour plate method on selective media. The total aerobic count ranged from 4.0 x 103 to 2.8 x 106. The result obtained showed that bacteria (Staphylococcus aureus) in bagged milk ar...
Phytochemical Screening And Invivo Antiplasmodial Activity Of Methanol Extract Of Baobab Leaves (Adansonia Digitata)
ABSTRACTTwenty-two healthy albino mice were grouped into A, B, C, D, and E. Group A had six mice while groups B – E had four mice each. The mice were infected with Plasmodium berghei and the methanol extract of the leaves of Adansonia digitata was obtained by maceration extraction method. Phytochemical screening of the plant extract revealed the presence of alkaloids, flavonoids, saponins, carbohydrates and cardiac glycosides. The infected mice Group C, D and E were orally treated with the ...
Bioefficacy Study Of Mosquito Repellent Produced From Ocimum Basilicum Using Aerosol Propellant As Carrier
ABSTRACTMosquito borne disease is a major public health problem globally, particularly the tropics being the major spot in the spread of malaria. The development of resistance to chemical insecticides has necessitated the research and development of natural mosquito repellent. The aim of this study is to extract, characterize and test the larvicidal activity of essential oil, produce mosquito repellent using the essential oil as its active ingredient and study the bioefficacy of the produced ...
Synthesis And Characterization Of Nanocalcium Titanate (Perovskite)
ABSTRACTAccording to a few recent studies, calcium titanate is a material that is similar to hydroxyapatite in biological properties. However, calcium titanate is not currently being used in the biomedical application as to hydroxyapatite. The objective is to prepare nano calcium titanate powder from the solution of calcium oxide, ethanol, and titanium (IV) isopropoxide via sol-gel synthesis. The fiber size, pore size and morphology were studied by phenom scanning electron microscope (SEM). T...
Studies On The Blastofiltration Potentials Of Selected Plant Seeds For The Treatment Of Lead And Cadmium Contaminated Water Samples
ABSTRACTPhytoremediation, based on the theory of botanic tolerance and accumulation of certain pollutant, is a new developing ecological technique primarily used to clean polluted environment. Blastofiltration is applied to phytoremediation of heavy metal polluted water at present. The study used castor, okra, melon and moringa seeds as experimental materials to investigate their potentials as possible blastofiltration materials. The results showed that with the trial time lasting up to 72 ho...
