Semiconductors are substances with electrical conductivity characteristics halfway between insulators and conductors. They are the basis for devices like transistors, diodes, and integrated circuits, crucial parts of contemporary electronics. The capacity to conduct electricity under certain circumstances, such as an applied voltage or exposure to light, defines semiconductors. Semiconductors can have their conductivity altered and regulated, unlike conductors, which have high conductivity, a...

SUMMARY Determination of melting point of vegetable oils and fats by differential scanning calorimetry (DSC) technique. Melting point of fats is used to characterize oils and fats and is related to their physical properties, such as hardness and thermal behaviour. The present work shows the utilization of DSC technique on the determination of melting point of fats. In a comparison with softening point (AOCS method Cc 3-25), DSC values were higher than those obtained by AOCS method. It has occ...
Considering a cluster of different hierarchical order with various barrier/cadre levels and steps within levels, there is non availability of structural framework to help to exclusively analysis, formulate, identify, differentiate and design standardized provisional values to cluster members at various barriers levels and steps with levels. This study invents stepwise analysis and generation of Kifilideen matrix structural framework for infinite terms of increasing elements of successive co...
ABSTRACT A total number of ten (10) locally fermented milk (nono) samples were collected from five (5) different retail outlet namely: Gombe main market, Jekadafari,Pantami, TashanDukku, and Tumfure. Bacteriological analysis was carried out on the samples for isolation and identification of bacteria associated with such products as well as total aerobic plate count. Seven (7) specie of bacteria which are of public health importance were isolated and identified. The percentage of occurrences o...
ABSTRACT Guava (Psidium guajava L) is native to South America and exists as both wild and cultivated. Guava has been used as a source of food and raw materials for pharmaceuticals. The aim of this study was to determine bioactivity of methanol and water extracts from apple guava against selected pathogenic bacteria. Study samples were collected from Tal, Gombe State, Nigeria and taken to the departmental herbarium for identification to obtain voucher number. Fifty grams of f...
ABSTRACT A study was carried out to investigate the effects of sulphuric acid, hot water and soaking of seed in water treatments on the germination of Bambara nut (V. subterranea) seeds were planted in poly pots for germination. 40 seeds of Vigna subterranea (one per poly pot) with ten replicates each were used. The highest germination was recorded in seeds soaked in water for 24 hours. Germination was observed to be low or slow in untreated (control) seeds. While there was poor or no resp...
ABSTRACT Comparative analysis of Tap, Borehole, Well and Package water in Gombe metropolis of Gombe State, Nigeria was conducted in order to examine their qualities with a view to determine their portability. A total of 8 water samples collected from four different functional water supply sources in the study area were subjected to physicochemical and bacteriological test and analyzed using standard analytical techniques and instruments. Most of the physicochemical parameters of the sample...
ABSTRACT A comparative study on the bacterial flora on the palms of students in Gombe State University was conducted in August 2014.120 male and female undergraduates students from the Faculties of Science, Education and Faculty of Arts and Social Sciences were sampled. Culture and biochemical tests were conducted. 66% of students were found to have high bacterial load, with male students having 60% and female students 40% on their palms. Overall, the results of this study reveals that male s...
ABSTRACT This study was carried out to determine the antimicrobial activity of seed oil of Moringa oleifera and garlic against some selected food-borne microorganisms (Staphylococcus aureus, Escherichia coli, Salmonella spp and Pseudomonas aeruginosa) using disc diffusion method. The antibacterial assay results shows that the seed oil of Moringa oleifera was inactive against all the tested organisms, even at 100 % concentration. In contrast, garlic oil was found to be active against all the t...
ABSTRACT Titrimetric method was used to analyze ten different brands of each vitamin C syrups that are sold in Gombe metropolis. The percentage of ascorbic acid content in vitamin C syrups containing 100mg/5ml showed that samples (1,2,3 and 7) having (68.37%,54.10%, 52.10%, and 74.00%) were below 95-105 recommended by British pharmacopeia limit. While for A samples (4, 5 and 6)have percentage ascorbic acid content of (95.00%, 95.10% and 96.00% )respectively and were within the normal ran...
ABSTRACT Studies of weed species found in found in federal college education (technical) were carried out using quadrant method, plant press was used for identification outside the field. The dominant among the weed families were Amarantaceae, Fabaceae, Lamiaceae, Sterculaceae, Papilionoideae, and Malvaceae. The prominent among weed species were the Unknown species, Leucas mutinicensis, Amaranthus spinosus, Sennaoccidentalis, and Sidacordifolia among others. This study clearly rev...
ABSTRACT The effect of aqueous leaves extract of Carica papaya (Linn) on some liver enzymesi.e; alanine aminotransferase ALT, aspartate aminotransferase AST, and alkaline phosphatase ALP, wasinvestigated.The phytochemical screening of the leaves extract of C.papaya was carried out at the beginning of the study. Albino rats weighing between 73-93g, of both sexes were used for the study.Caricapapaya2 ml of 0.11 g/ml aqueous leaves extract was orally administered daily to each of the experimen...
ABSTRACT This study was conducted to determine the effect of deforestation on soil productivity in Filiya Shongom L. G.A, Gombe State. Two plots were sampled using wandering quarter method of vegetation sampling, each measuring l00m x l00m. One site was assigned undisturbed area and the other one disturbed area. At each site Relative abundance, Basal Area, were calculate. T-test as used to determine the significance difference between the soil organic matter content, plant abundance, and basa...
ABSTRACT In an effort to ensure stable availability of good and safe water supply in all state of the federation (Nigeria), the production of packaged water (sachet and bottled water) was born; this has become the most available and affordable alternative to the general population. Hence compliment the inadequate supply of pipe borne water in most urban cities. Unfortunately, the quality of most sachet water sold to the public is uncertain and highly questionable. This study is aimed at ass...
