Si-NPs were synthesized using sorghum straw, characterized using Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy, SEM/Energy Dispersive Spectroscopy, X-ray Spectroscopy (EDS). Assessment of the results carried out on the synthesized Si-NPs revealed the following: FTIR showed absorption bands at 790.20, 1051.10, 1636.30, and 3403.10 cm-1 indicating the presence of Si-H, Si-O-Si, Si-O and Si-OH respectively. XRD analysis showed that the Si-NPs had an average size of 30.46 nm. SEM analysis showed that the Si-NPs were made up of amorphous mesoporous structures. The elemental composition of the sample was found to be 65.33 % Si, 12.77 % O, 11.05 % Al, 5.23 % Fe, 3.42 % C and 2.20 % Na. The result from the germination study demonstrated that as the concentration of Si-NPs increased from (0-8 g/L), the germination rate and vigour index of seeds also increased, with 8 g/L having the highest germinated seedlings. The control which has no Si-NPs recorded the least seedling growth. The study of the germination time also showed that seeds with the highest Si-NPs concentration of 8 g/L, germinated within the least germination period (2 days) when compared with the germination period of the control. This research has shown that increase in concentration of Si-NPs have a positive effect on the germination of Beta vulgaris (Beetroot).","PeriodicalId":213779,"journal":{"name":"Dutse Journal of Pure and Applied Sciences","volume":" 88","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141826892","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}

In this study, Moringa oleifera leaf extract (MLE) was used as a plant growth stimulator for Amaranthus hybridus, using two different application techniques (priming and foliar spraying). The treatments used for the experiment were 10%, 20%, and 30% MLE solutions, and 10%, 20%, and 30% mg/L gibberellic acid (GA3) solutions, and distilled water. Viable seeds of A. hybridus were primed with MLE treatments and sown in 21 different polythene bags filled with top soils. Similarly, seeds of A. hybridus were sown in another 21 polythene bags and sprayed foliarly every two days for four weeks. All the 42 bags were arranged in a Completely Randomized Design at the screened house of the Botanical Garden, Lagos State University. The results from the growth analysis showed that although 20% GA3 had the highest value of 14.37 cm for shoot height (p<0.05), 30% MLE was the closest among the MLE treatments with 9.12 cm. While there was no significant difference across the samples for stem girth and number of leaves (p>0.05), there was a standout performer for chlorophylls. 30% MLE recorded the highest values of 9.33 mg/100g, 4.67 mg/100g, 14.00 mg/100g for Chlorophyll a, b, and total chlorophyll, and all with significant differences. Interestingly, all the best performing treatments were from A. hybridus plants cultivated using the foliar spraying techniques, thereby making it a better application technique than the phytopriming. Generally, the 30% MLE displayed the best potential in the stimulation of growth and enhancement of chlorophyll contents of A. hybridus which could be of great value to those in the agriculture, food and pharmaceutical industries.","PeriodicalId":213779,"journal":{"name":"Dutse Journal of Pure and Applied Sciences","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141827296","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}

Swab samples were inoculated using streak plate and incubated at 24 hours at 37oC. The samples were sub-cultured after 24 hours and identified based on cultural characteristics, morphology and biochemical tests. The bacteria isolated include Staphylococcus epidermidis, Staphylococcus aureus, and Bacillus cereus from nasal swab samples while Staphylococcus epidermidis and Staphylococcus aureus were isolated from hand swab samples. The frequency of occurrence of the bacteria recovered from hand was Staphylococcus epidermidis 7(70%), Staphylococcus aureus 3(30%) while Staphylococcus aureus 5(50%), Staphylococcus epidermidis 2(20%) and Bacillus cereus 3(30%) were recovered from nasal swab respectively. The antibiotic susceptibility and resistance pattern exhibited by the recovered isolates from the nasal swab showed that 10(100%) of all the isolates were susceptible to Pefloxacin, Ciprofloxacin, Streptomycin and Co-trimoxazole(septrin) respectively while 0(0%) of the recovered isolates were resistant to Cefuroxime respectively whereas the recovered Staphylococcus epidermidis from the hand swab had 5 (71.4%) which were susceptible to Gentamycin, 3(42.9%) which were susceptible to Ampiclox, 2(28.6%) which were susceptible to Rocephin, and 5(57.1%) were susceptible to Erythromycin.

This research paper explores the economic contributions of primary waste scavengers (i.e waste pickers) in Urban Yola North, highlighting their significant contribution in turning waste into money. The paper focuses on how scavenging helps to build a more sustainable urban environment by producing cash, employment, and raw materials for the recycling sector. Drawing on a sample of 205 waste scavengers through surveys and interview, the findings reveal that majority (88.73%) derive economic benefits from their work; in addition to 1.95% presented environmental motivations. More than half of the respondents (54.15%) report a monthly income between N11,000 and N20,000, with smaller proportions earning higher incomes. These findings offer valuable insights into the economic contributions of waste scavengers in Urban Yola North. This research expands our understanding of waste-to-wealth initiatives in similar urban settings, laying the groundwork for broader discussions and strategies to enhance the well-being and livelihoods of waste scavengers, ultimately contributing to sustainable livelihoods in urban centres. The study recommends provision of social security such as social assistance programs and other interventions to reduce their social exclusion, and employer and employee rights should be maintained by law, between the waste pickers and their masters (middlemen) in order to reduce extortion in the industry. Formalization of the occupation will also be considered to improve the nature of their operation and ensure their safety.","PeriodicalId":213779,"journal":{"name":"Dutse Journal of Pure and Applied Sciences","volume":" 65","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141825448","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 variations in the optical absorption coefficient, refractive index, extinction coefficient, reflectivity, and optical conductivity was examined over a range of temperatures and crystallographic orientations ([100], [010], [001]). The findings indicate that as temperature rises, there is a general decrease observed in the absorption coefficient, refractive index, extinction coefficient, and optical conductivity. Similarly, reflectivity also tends to decrease with increasing temperature. These findings suggest that Cubic CH3NH3SnI3 exhibits consistent transparency, a stable refractive index, and relatively high reflectivity across different temperature conditions. Its low optical conductivity, typical of semiconductor materials, indicates its suitability for facilitating efficient charge separation and transport within solar cells.
