Abstract

This study was carried out to compare to the Nutritional and the Anti-nutritional composition of Laurus nobilis (Linn) to the standard of World Health Organization (WHO) Nutritional and anti-nutritional composition of vegetable spices. The bay leaves samples were analyzed for percentage (%) moisture content, ash content, Lipid, crude fibre, crude protein, carbohydrate contents and the energy value in Kcal/100g. of the samples were determined in triplicates to ascertain the nutritional quality of the leaves. The proximate analysis revealed that Bay leafs contain moisture (11.80 ± 0.54%), Ash (5.50 ± 0.10%), Crude fibre (26.12 ± 0.11%), Crude Protein (4.10 ± 0.10%), Lipid (8.14 ± 0.06%), Carbohydrate (70.46 ± 0.22%) and the energy value (371.5Kcal/100g). The Mineral composition (mg/100g) of Bay leafs showed Magnesium with (528 ± 0.02) to be the highest followed by Iron (457 ± 0.10), Sodium (378.5 ± 1.16), Phosphorous (327.318 ± 0.47), Calcium (307 ± 1.51), and lastly Potassium with (187.5 ± 2.65). The minerals analyzed were found to be below the permissible limit set by the standard organizations such as World Health Organization (WHO) and Food and Agriculture Organization (FAO). The Anti-nutrients compositions are Alkaloids (3.4 ± 0.02%), Flavonoids (0.177 ± 0.001%), Phytic Acid (0.836 ± 0.02%), Oxalate (7.13 ± 0.02%), Cyanide Glycoside (474.281 ± 10.002mg/kg). The results showed that Laurus nobilis contained essential and valuable nutrients which are beneficial to human health and that boiling of the leafs for about 5 minutes will effectively reduce the Anti-nutritional content which inhibits the absorption of the nutritional composition

Abstract

The experiment was carried out in other to evaluate the effect of dietary cholesterol on growth and survival of Clarias gariepinus at different inclusion levels of 0%, 0.25%, 0.50%, 0.75%, 1.00% for the period of 8 weeks. 150 fingerlings of Clarias gariepinus were randomly selected into five treatments: three replicates each per treatments with ten fish per tank. Five experimental diets were prepared, a control diet without cholesterol inclusion (T1), 0.25% cholesterol inclusion (T2), 0.50% Cholesterol inclusion (T3), 0.75% cholesterol inclusion (T4), and 1.00% cholesterol inclusion (T5). The treatments with 0.75% cholesterol inclusion have the highest weight gain (86 ± 0.11g) compared to other treatments, while treatment with 100% cholesterol inclusion have the second highest weight gain (82.5 ± 0.10g). The fish in Treatment two (T2) have the lowest specific growth rate (2.02 ± 0.03g) followed by treatment with 0.50% cholesterol inclusion which have the second lowest specific growth rate (2.06 ± 0.04g), while the treatment with 0.75% have the highest specific growth rate (2.19 ± 0.07g). The fish in T4 have the highest final weight (226.3 ± 0.16g) compared to other treatments. The fish with 0.75% and 1.00% inclusion of cholesterol performs better than others in the experimental diets. Treatment four (T4) have the lowest feed conversion ratio (0.58 ± 0.05g) which implies that it has the highest specific growth rate because the lower the feed conversion ratio the higher the specific growth rate. It could be concluded that the cholesterol inclusion up to 0.75% have no negative effect on the growth performance of Africa catfish (Clarias gariepinus).

Abstract

An effort to partially replace carbon black as a filler in natural rubber polymers was attempted due to global concern on carbon black becoming a potential health risk to humans. More so incorporating natural starch as a biofiller in natural rubber through a new latex compounding procedure has introduced a new dimension in reducing the particle size of starch granule from few micrometer to nanoscale allowing it to mix and blend thoroughly with the natural rubber molecules supposedly at molecular level in the liquid medium during the co-coagulation process and at compounding. Enhancement in macro properties was observed when Polynesian arrow root (PAR) starch filler was introduced into natural rubber biopolymer in gelatinized form at 30 parts per hundred rubber (phr) in a latex compounding procedure. The PAR starch/natural rubber blend was compounded in a two-roll mill and cured by Sulphur vulcanization and accelerators system according to ASTM standard method, D3184-80. There was improvement in tensile strength, resilience and hardness in the newly formulated biopolymer-for tensile strength, PAR starch/natural rubber is 57.43Nm-2, unfilled rubber (NR) is 21.90Nm-2 and the Control (Carbon black filled Natural rubber) is 87.63Nm-2. X-ray diffraction analysis showed that the formulated biopolymer is semi crystalline. Fourier Transform Infra-red (FTIR) revealed the presence of the carbon-carbon double bond of cis-1, 4-polyisoprene molecule at stretching band of 1644.5cm-1 while O-H stretch for free hydroxyl and OH bonded gave 3865cm-1 and 3476cm-1 indicating the presence of starch molecule in the PAR starch/NR biopolymer. More so higher values of crosslink density from swelling tests, 33.5, 33.1 and 44.0molcm-3 at 10, 20 and 30phr filler loading is an evidence of strong filler-rubber interaction and adhesion at the interfaces produced by the hydrodynamic effect. Second evidence of strong filler-rubber interaction is the absence of phase separation during and after the compounding and curing processes hence PAR starch filler can partially replace carbon black as filler in natural rubber biopolymers with application in automobile tire manufacture with cost, weight and energy saving advantages.

Department of Science Laboratory Technology, Federal Polytechnic Bali, PMB 05, Bali, Taraba State, Nigeria.

 

Abstract

Eczema, an atopic dermatitis is one of the most economically important skin disorder, therefore remedial attention needs to be given to it. Unlike the orthodox belief, eczema is a genetic disorder of the epidermis (filaggrin, CARD 11 or KIF3A gene mutation) not an infection, therefore, treatment must be targeted towards correcting this rather than targeting Candida albicans, the yeast that infects the eczematous skin as a result of environmental exposure. Currently, all types of chemically synthesized products used either topically or as tablet prove to be either expensive or have one or more side effects. This research paper recommends a natural topical treatment with the fresh leaf extract used traditionally in decades past, Mitracapus scaber, after careful comparative analysis with three other ointments sold (sulphur ointment, skineal and hydraulic fluid). Thirty two consenting individuals with eczema were sampled using accidental and purposive sampling methods, eight from four areas selected randomly in Bali metropolis (Friday Market, Daniya Village, Sabo Layi and Angua Tiv). Each treatment for two individuals was repeated for four times at four days intervals. Re-observation one month after showed complete normal skin for all M. scaber treatments while partial and complete relapses were observed in other three treatment ointments.  Similarly, M. scaber demonstrated antimicrobial activities on Candida albicans. Therefore, M. scaber can both correct filaggrin, CARD 11 and KIF3A gene mutations of the skin and eliminate the secondary yeast infection. Also, it is easily accessible and it has no side effect.

School of Remedial and Continue Education (SORCE), A.D. Rufai College of Education, Legal and General Studies Misau

 

Abstract

Heavy metals are those metals that have a density greater than 5.og. They are found as trace elements in the natural environment, however, presence of heavy metals in water and edible vegetables in excess of the recommended amount set by the WHO (world health organization and FAO (Food Aid Organization) is very dangerous and harmful to the life and health of the people. This paper reports some studies conducted that shown the presence of these heavy metals notably Pb, Cd and Mn in excess of the recommended level set by WHO and FAO in the ground water samples collected. Similarly, the presence of Ni, Pb and Cd in excess amount was found in the vegetables specifically tomatoes and Onions used in Misau Town. Hence, this paper suggests an urgent need for remediation and regular monitoring of the ground water and vegetables use in Misau Town, Bauchi State.

Abstract

The importance of Mathematics cannot be underestimated because it has its limb in virtually all fields of study either not to discuss its influence in the Mathematical related fields. In fact, Mathematics is the pivot on which all sciences; engineering, business and even social sciences revolve. Because of its importance many institutions of higher learning require a credit pass from senior secondary school students who seek admission to study various courses in their institutions. The study aimed to determine the extent of associations or relevance of physics and mathematics. Based on our findings, we suggest that an upper secondary physics education preparing pupils for tomorrow’s society should be characterized by variety, both within and among courses, integration of mathematics in the physics courses. Physics is best understood by the student with good mathematical background. We recommend that only student with sound mathematical background will be engage in physics classes and should be introduce from junior classes with proper sequential arrangement of topics base on degree of complexity and relevant projection.

Abstract

The researchers in this paper use mechanochemical synthesis as a panacea for the excess use of solution based syntheses that cause environmental contamination. The main aimed of the paper is the usage of mechanochemicaly synthesized complex of ciprofloxacin which was characterized by physical methods, spectral and biological studies. Spectral studies show that; in the complexe, the ciprofloxacin acted as bidentate ligand which coordinated to the metal ion through the ring carbonyl oxygen and one of the oxygen atoms of the carboxylate group. Results from microanalysis data shows 1:2 metal to ligand ratio. All the complexes show strong antibacterial activity at all concentrations compared with the free ligand (ciprofloxacin). Due to environmentally friendly, shortest reactions time, inexpensive, production of higher yields. Therefore, the authors recommend the use of mechanochemical methods over solution-based.

Abstract

The production of pap is still largely a traditional formula and done in homes in crude manner which might be contaminated by bacteria due to poor hygienic and sanitary condition in the preparation, handling, and preservation. The aim of this work is to isolate and identify pathogenic microorganisms associated with different methods of storing pap. Fresh prepared sample of pap was divided into four parts. One part was kept in the refrigerator the second was dried and the third was kept in a plastic container in which water was added to it. The fresh part was analyzed immediately while the 1,2,and3 parts was kept for 5days before analysis. 1ml aliquot of serial dilution of each sample was plated on an appropriate media. Identification was based on cultural, microscopy and biochemical characteristics. The result reveal the presence of the following organisms; staphylococcus aureus, Escherichia coli, Klebsilla species and Bacillus species. The sample stored with water shows the microbial count of 3.5×103, freshly prepared sample 1.3×103, dry sample 2.9×103 and refrigerated sample 1.8×103. The sample stored with water show the highest microbial count while the freshly prepared sample shows the least microbial count. From the research the best method for storing pap is to refrigerate. Also hygienic condition should be observe during preparation and handling.

Abstract

Silica of high purity and good surface area was beneficiated from rice husk by the application of heat in a standard solution of hydrochloric acid to produce rice husk ash after calcination at a temperature of 750 oC for 2 hours. Silica gel was then synthesized using sodium hydroxide (NaOH) to solubilize the silica present in the ash with the application of heat on the rice husk ash. Therefore, Rice Husk Ash (RHA), Cleaned Rice Husk Ash (CRHA), and Silica Gel (SG) tagged Samples A, B, and C respectively were summarily developed from the synthesis processes. The samples were tested for moisture adsorptivity using laboratory desiccator. Sample C had the highest moisture adsorptivity of 24.34%, followed by Sample B with 15.29% adsorptivity, while the percentage adsorptivity for Sample A was 3.52. In addition to moisture Adsorptivity test, the various characterizations carried out on the samples proved their potential of applicability as desiccants; such as the presence of Silanol functional group, and good surface area especially for the SG sample. Also from the BET analysis of the SG Sample it was found to be a mesoporous material having a pore width value of 2.92 nm, pore volume of 0.1886 cm3/g, and the surface area of 407.6 m2/g. X-ray fluorescence (XRF) Spectrometer was used to determine the elements and the oxides present in the Rice husk ash (RHA), Cleaned rice husk ash (CRHA), as well as in the Silica gel samples.

Abstract

There have been factors mitigating the success of sustainable solid waste management in Nigeria, these includes poverty, population density, industrial growth etc. Governments at Federal, States and Local level enact environmental laws for environmental protection, but enforcement of such laws is a challenge especially in Nigeria. Performance at State level is not commendable as a result of political, social and economic factors. This research aimed at evaluating the problems of Solid Waste Management in Jimeta-Yola Nigeria and way forward. The research findings has recommend, the statutory responsibility of the organization has clearly spelled their duty of collection, transportation and disposal of solid waste in an environmental friendly manner. Among the main challenges discovered, lack of regular release of funds for the purchase and maintenance of waste collection facilities, population outburst in 2014 increased the generation of approximately 2,041 daily tons of municipal solid waste in the city. This problem was caused by insurgency in the north-eastern Nigeria. Hence the aforementioned upsurge has seriously led to break down of waste evacuation and transportation vehicles by overstretching their activity. The organisation has 9 vehicles, presently only two are functional. It is therefore recommended to have a sustainable solid waste management in Adamawa state it requires public-private partnership in providing health, safety, and environmental training on how to turn solid waste into resource, as a panacea toward boosting the local economy while keeping the streets clean.
