MECHANOCHEMICAL SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL ACTIVITIES OF BENZYL-N,N-DIMETHYL DITHIOCARBAMATE AND ITS FE3+ COMPLEX

ABSTRACT The strategy of utilizing mechanochemical synthesis to obtain metal-organic frameworks with high surface area and nanodisperse particles has been espoused. Transition metal ions have been shown to form complexes with organic moieties such as benzyl-N,N-dimethyldithiocarbamate. It has been established that iron in its oxidised state (Fe3+) is cidal to microorganisms and dialkyldithiocarbamates have an established antifungal activity, the complex of Fe3+ and benzyl-N,N-dimethyldithioc...

CONSTRUCTION AND CALIBRATION OF A LINEAR VARIABLE DIFFERENTIAL TRANSFORMER (LVDT)

ABSTRACT A Linear Variable Differential Transformer (LVDT) was constructed having a primary 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, ±0.271V and ±0.395V for displacements of±0.00cm, ±2.00cm, ±4.00cm, ±6.00cm, ±8.00cm and 10.00cm respectively. Thedevice when used ...

Comparative Studies on The Bacteria Associated With Hands of School Pupils’ in Kaduna South Local Government

ABSTRACT This 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 t...

Determination Of Heavy Metals In Some Cosmetic Products Commonly Used Among Students Of Kaduna Polytechnic

ABSTRACT The 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 acids. ...

Synthesis, Characterization And Antibacterial Properties Of Nickel (Ii) Amine Malonate And Nickel (Ii) Amine Tartarate

ABSTRACT Nickel 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 antibacterial acti...

Bacteriological Quality Of Some Selected Bagged Milk Sold In Markets Within Kano Metropololis

ABSTRACT Milk 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 a...

Phytochemical Screening And Invivo Antiplasmodial Activity Of Methanol Extract Of Baobab Leaves (Adansonia Digitata)

ABSTRACT Twenty-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...

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

ABSTRACT Phytoremediation, 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 ...

ENHANCING COMPUTER EDUCATION THROUGH THE APPLICATION OF MASS-MEDIA

ABSTRACT The on-going fusion between Computer education and mass media has transformed the world in which we live into a “global village” where students can easily get in touch, see or speak to one another and exchange information is multimedia, electronically, from any point on the globe to another. This important development of computer education has been acknowledged as the practical tool for national development. This paper examines ways to enhance computer education through the a...

The Role of Chemistry Teacher in the Development of Science Education in Nigeria

AbstractThis work titled The Role of Chemistry Teacher in the Development of Science Education in Nigeria is specifically designed to find out and discuss the various ways science education has been lagging in Nigeria and how chemistry education can help to remedy the situation. In the course of this, some issues were discussed  such as the concept of chemistry, chemistry education, science education, objectives of chemistry education, problems facing science education in Nigeria and ways to...

Effect of spent Engine oil on the growth of Spinach

ABSTRACT The effect of spent engine oil on soil properties and growth of Spinach (Spinacia olereacea) was investigated. Five treatments (0, 20, 40, 60, 80)ml of the spent oil were applied to soil in perforated poly bags with Spinach strands at four weeks after stabilization. Soil analysis showed that spent engine oil had no effect on both the pH and texture of the soil. Organic C, Na and Mg in the contaminated soil increased compared to control. There was decreased in concentration of P due t...
