Descriptive statistics and gross margin analysis were used for data analyses. Findings of thestudy revealed that Majority (63.53% and 76.40%) of project beneficiaries and non-project beneficiariesrespectively did not attain any form of formal education. Cost of fertilizer dominated the production cost for boththe project beneficiaries (46.61%) and non-project beneficiaries (55.99%) of total cost. Result of the gross marginanalysis shows that the project participants made more profit in dry season onion production (₦241, 854.89)compared to the non-project participants (₦63,328.59). It was recommended that Fadama III project should as muchas possible expand their area of operation so that more farmers can benefit from their services.","PeriodicalId":158544,"journal":{"name":"Equity Journal of Science and Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126638497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The leaves ofAlchornea cordifolia were extracted with ethanol which was partitioned with ethyl acetate to obtain the ethanolextract and ethyl acetate fraction respectively. The extracts were screened for basic phytocompounds and subjectedto antibacterial assay against bacterial isolates from infected wounds which include Pseudomonas aeruginosa,Staphylococcus aureus, Klebsiella spp, Enterobacter spp, Citrobacter spp, Escherichia coli, Proteus mirabilis andProteus vulgaris. Agar well diffusion method was used to determine the antibacterial activity of the extract andfraction. Phytochemical investigation revealed the presence of carbohydrates, cardiac glycosides, saponins,flavonoids, tannins and alkaloids. The zone of inhibition ranged between 1.0 - 32.2mm for the entiremicroorganisms. This variation in level of the activity among the extracts could be due to the difference in solubilityof the active ingredient in each solvent on one hand and to the constitutional or structural variability of the testedorganisms on the other hand. The results of the study showed that the ethyl acetate fraction of Alchornea cordifolialeaves possess high level of antibacterial activity against bacteria associated with wound infection.

Semiconductor diodes are themost common types of photodetectors that are widely considered. Indium Arsenide (InAs), being an AvalanchePhotodiode (APD), has become a solid-state photodetector of choice owing to its ability to detect infrared light ofup to about 3.5 μm. In this work, the depletion width and electric field profile of p-i-n InAs were simulated andused to obtain the multiplication gain. The effect of combining a series of p-i-n InAs in order to obtain longerdepletion width for the purpose of achieving high multiplication gain was investigated. To achieve this main target,the work was designed in two stages. The first stage involved designing a simple p-n junction of InAs to test themodel. Further improvement of the design to increase the depletion region was carried out by sand-witching anintrinsic piece of semiconductor material between the p and n-regions to form p-i-n InAs. The results obtainedshowed that the modification led to an interesting increase in the depletion width, electric field and themultiplication gain. In the second stage, the series of p-i-n InAs were combined to form an “Advanced solid-statephotomultiplier”. For the first time, a larger depletion width was achieved and thus increased multiplication gain.The results presented deduced that this novel design is promising since an appreciable gain much greater than 1000was achieved at about 6 V. Therefore, this could be used as an alternative to photomultiplier tube as well as otherexpensive photodetectors available.","PeriodicalId":158544,"journal":{"name":"Equity Journal of Science and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129305028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is toinvestigate the viability of DNA obtained from burnt teeth for forensic sex-determination. Two DNA extractionmethods consisting of silica based commercial kit and phenol-chloroform organic method, followed by polymerasechain amplification of amelogenin gene for sex determination were employed. Based on the DNA yield and opticaldensity values, the kit extraction method performed better than the phenol-chloroform method with 100% and85.71% success respectively. A Mann-Whitney U test of 260/280 absorbance showed no statistically significantdifference in the median absorbance for aviation fuel (median = 1.34) and gasoline (median =1.32) burnt samples.Amplification of AMEL genes using the commercial kit and phenol-chloroform method were 52.38% and 22.22%positive respectively compared to pre-extraction sex determination.
