Study of Soil Management for Cassava Production in Isoko, Delta State Nigeria
Get PDFThis research work examined soil management for cassava production in Isoko, Delta State, Nigeria. The study adopted an exclusive field survey method. This involved the collection of soil samples in-situ for laboratory analysis. The study area was grouped into four zones based on close boundary villages. Major soil physicochemical parameters needed for cassava production were the main crust of the scientific investigation. They include NPK and soil pH. Results obtained from laboratory analysis, data were compared with minimum benchmark standards and threshold using FAO standards of land evaluation for cassava production. Results obtained from the soil analysis showed that Nitrogen is deficient in the soil with the value of (0.0325%) against the backdrop of FAO threshold standard of (1.5231%). Potassium was also found to be deficient in the soil with a mean value of 0.2895 cmol/kg which is below the FAO required threshold standard of 1.6350 cmo/kg needed for effective production of the yield of tubers. Phosphorous though present in fairly adequate quantity, with a mean value of 2.4250 cmol/kg compared with FAO threshold of 3.1252 cmol/kg, its effective utilization may be highly impaired as a result of Nitrogen deficiency. Soil pH of 5.90 falls within the range of slightly acidic soil against the required standard of 7.0 which is considered natural. To test the hypotheses, postulated for the study, the ANOVA statistical tool was used to ascertain if a significant difference exists in the soil nutrient across the various zones. Based on the decision rule for f-ratio, the (F-cal) is 0.079 while the table value is 4.07 at 0.05sig. The implication is that there is a significant difference between the required standard and the observed. The study thus confirmed that the soils of the study area are deficient in vital soil nutrients required for cassava production. Nutrient deficiency is, therefore, a major constraint to cassava production in the area. Strategies to ameliorate the soil constraints were also advanced

Secure Door Control System using RFID Card
Get PDFThe proposed system is an automatic identification and authentication system which can be deployed at the doors of the building to authenticate authorized people. The keypad requires that a person desiring to gain access enter a correct code number. Where access control keypads are used in place of card readers, only a correct code is required to allow entry. This system is also known as the barcode system. So Door Security System is necessary for every home, office, campus and buildings. In this system, a door lock can be controlled by an RFID card. Radiofrequency identification (RFID) is a wireless technology that can be used to develop the access control system. It will be the intent to expand and implement an electronic system that will allow campus police/ administration to automatically secure access to building rooms in buildings across all campus locations in case of emergency and to have views into areas when emergencies may occur while helping to alleviate placing anyone in harm’s way. This approach not only reduces the cost but also enhances the reliability and ease of maintenance of the authentication system
The Association of Physical Activity and Diet with Metabolic Syndrome among University Students in Kenya
Get PDFThe occurrence of these lifestyle related practices and dietary habits at early age has been shown to increase the predisposition towards metabolic syndrome. Metabolic syndrome refers to disorders occurring together resulting in an increase in the risk of diabetes and cardiovascular diseases. Prevalence rate was established at 1.9% indicative of occurrence of predisposing risks of metabolic syndrome in university students. A cross-sectional, quantitative research design was used. 323 participants were sampled from a population of 40,000 students with stratification according to the various school sizes. A self-administered questionnaire was used to collect data. 61.3% of the respondents did not exercise regularly, 72.3% snacked frequently, 60.6% of the subjects that were not diagnosed with metabolic syndrome were fit, 37.2% needed to work on their fitness while only 2.2% were out of shape. The relationship between sedentary lifestyle as a risk factor and metabolic syndrome was statistically significant, as was the relationship between dietary habits and metabolic syndrome. The study established that 85.4% of the subjects were not sure of the amount of calories they consumed in a day and 13.9% of the subjects reported they had weight issues that affected their academics. Modifications in lifestyle habits, physical activity and dietary composition can result in a positive impact on metabolic syndrome and its progression. A mandatory extra co-curricular program requiring students to participate in exercise and sports activities should be enforced to positively engage university students. Vulnerable groups such as the pre-hypertensive and obese should also be closely monitored

Investigating the Performance of Ghana’s Locally Produced Alcohol (Akpeteshie) in Stripping Gold-Loaded Carbon
Get PDFGold adsorbed unto activated carbon is recovered downstream via various stripping techniques paramount among which are the Zadra elution method and the Anglo American Research Laboratory (AARL) method before final gold recovery by electrowinning. These conventional stripping systems require a relatively higher temperature and longer elution hours. These are effective but the relatively longer extraction times that accompany them have been a major concern over the years. This has encouraged diverse research operations to ascertain an alternative method of elution that would render the process more economical. One research finding that has been very successful in reducing the extraction time significantly is alcohol stripping. Laboratory produced ethanol, methanol, isopropanol, and ethylene glycol have all proven to be effective in stripping gold from loaded carbon at elevated temperatures. One main hindrance to the usage of this method at the commercial scale is the relatively higher cost of ethanol among other operational and environmental challenges. This work investigates the performance of Ghana’s locally produced alcohol (akpeteshie) in stripping of gold from gold-loaded carbon at lower temperatures with the aim of finding an alternative method for gold stripping which might be cheaper than conventional systems. Cost analysis conducted revealed that akpeteshie is relatively cheaper than laboratory-produced ethanol. This was one of the key motivations of the research work. A range of different strip solutions were used (hydro-ethanol, caustic solution and lastly caustic and ethanol mixture). The experimental work was carried out at the laboratory scale, using gold-loaded carbon at room temperature and at 60 and 70 °C temperatures respectively and up to 8 h extraction time. Hydro-ethanol was the most rapid eluant with 66% Au eluted after 8 h at 70 °C, followed by the ethanol and caustic mixture which yielded 42% extraction after 8 h. Caustic was the least effective with 8 h required for a 20% extraction yield. Interestingly, 92% Au extraction was obtained at 70 °C when hydro-ethanol was used as an eluant to strip fine carbon
