Abstract: Alkaline proteases are one of the classes of protease enzymes which are extensively used in detergent and tanning industries. Currently, there is an increasing demand for biocatalysts from extreme environments that are important sources of microorganisms routinely used in novel industrial enzyme production. In this research attempts were made to isolate and screen for an alternative alkaline protease producing fungal species from abattoir and food wastes. Hence, fungal species were...
Abstract: Lignocellulosic biomass is one of the most suitable alternative energy sources, whichcan be harnessed to meet the challenges of energy security. Energy resources such as petroleum and coal are being utilized at a rapid rate and eventually run out. Therefore, this research was initiated to find an alternative substrate for the production of ethanol from a cost-effective substrate. Parthenium leaf and stem were collected from Haramaya University. The collected Parthenium leaf and ste...
Abstract: Watermelon is one of the major utilized fruits grown in the warmer part of the world. The juice or pulp from watermelon is used for human utilization, while rind and seeds are major solid wastes. Endophytic microbes have been an important and potential resource of bioactive compounds. The present study was undertaken to assess phytochemical analysis, antioxidant and antimicrobial activities of endophytic fungal isolates from water melon seeds and fruit rind. The watermelon seed and...
Abstract: Laccase (EC 1.10.3.2, benzenediol oxygen, oxidoreductases) is typically extracellular monomeric glycoproteins that belong to the multicopper oxidase family. Laccase is widely distributed in higher plants, bacteria, fungi, and insects. Laccase play an important role in different industrial sectors, soil bioremediation and biodegradation of environmental phenolic pollutant and removal of endocrine disruptors. Laccase has been efficiently applied to nanobiotechnology due to their abil...
Abstract: Bioactive natural compounds isolated from fungal endophytes have been playing a promising role in the search for novel drugs and becoming an inspiring source for researchers due to their enormous structure diversity and complexity. Therefore, the present study was undertaken to assess antioxidant and antimicrobial activities of endophytic fungi from garlic bulbs and leek leaves. The study involved garlic (Allium sativum) bulb and leek (Alllium Ampeloprasum var. porrum) leaf samples...
Abstract: Production of biogas through anaerobic digestion of organic waste materials provides an alternative eco-friendly renewable energy source. Anaerobic digestion is a technology widely used for the treatment of organic waste for biogas production. Therefore, the study was conducted to investigate the production of biogas from Wild oats co-digested with goat manure through anaerobic digestion with five treatments. The treatments were made into five treatments by mixing substrates in dif...
Abstract: This research was conducted with the objective of developing yogurt from camel milk using exopolysaccharides producing lactic acid bacteria, starch and camel milk powder to improve the texture and other quality characteristics of the product and to evaluate the sensory values of consumer’s acceptability. The experiment was conducted as Completely Randomized Design with one way Analysis of Variance. Physicochemical properties of raw camel milk and yogurt, viscosity, syneresis, tex...
Abstract: Artificial insemination technology of dairy cattle is a popular technology to improve the performance of new breeds. But, the adoption and utilization of the technology by dairy cattle owners in Ethiopia in general and study area in particular is very low. This study was conducted in Bedele Woreda of Buno Bedele zone of Oromia National Regional State with the aim of assessing determinants of adoption decision and intensity use of artificial insemination technology of dairy cattle. ...
Abstract: A study on characterization of milk cattle production potential, milk processing, marketing and chemical composition analysis were conducted in Agarfa District of Bale Zone. For this study two rural and two peri-urban milk production potential kebeles and total of 150 respondents from study were purposively selected. Data were collected through interviewing selected farmers, from field visit, focal group discussions, monitoring and laboratory analysis supported with secondary infor...
Abstract: Tasmanian devils are the largest living carnivorous marsupial found in the wild of Tasmania. These species are being threatened by a cancerous tumour disease, the Devil Facial Tumour Disease (DFTD). The disease affects the facial areas and has led to a considerable popula tion decline. In this thesis, mathematical models for transmission of DFTD are developed and analysed to investigate the significance of feeding and mating related contact, optimal control and fractional-order cha...
Abstract: We have recently argued that, because microbes have pervasive – often vital – influences on our lives, and that therefore their roles must be taken into account in many of the decisions we face, soci ety must become microbiology-literate, through the introduction of relevant microbiology topics in school curricula (Timmis et al. 2019. Environ Micro biol 21: 1513-1528). The current coronavirus pan demic is a stark example of why microbiology literacy is such a crucial enabler of...
Abstract: Engine efficiency could be increased if valve timing could change with engine revolutions per minute. Poppet valves are fitted with strong springs which return them to their rest positions after being pushed down by cam lobes. Overcoming the spring loaded camshaft drive train requires a lot of engine power. Valve lift, lift duration and phase cannot be adapted with cam lobes on the camshaft but electromagnetic actuators or hydraulic/pneumatic phasing mechanisms could achieve change...
Abstract: In attempting to answer the question of whether the Office of the Auditor General is doing enough to protect the sensitive data in its possession, I start off by stating the current information security trends. The trends highlight an upward rise in data breaches despite the numerous traditional approaches to secure data and network resources like firewalls, antiviruses, anti-malware gateways etc. In validation a study is performed at the Office of the Auditor General. Analysis of ...
Abstract: The objective of this study is to engage in a practical analysis that will investigate the effects of using Blackboard Learn as a learning platform for higher education students in Lesotho using Botho University as a case study. A mixed method approach was adopted for the study. Data was collected using in-depth interviews and a questionnaire from 132 participants randomly selected for the quantitative aspect and 30 participants purposively selected for the qualitative aspect, from...
Abstract: Enterprise Resource Planning (ERP) systems are one of the technologies that many organisations, including Small and Medium Enterprises (SMEs), have adopted. However, most of commercial ERP packages are designed for large-scaled companies. More complex nature of business processes in large companies makes it difficult for SMEs to adopt commercial ERP packages. The high costs of ERP system implementation mean that SMEs need to seek for alternative solutions which are less expensive....
