Abstract This study was designed to investigate the microorganisms associated with palm oil mill effluent (POME) in Johor Bahru state, Malaysia. Biodegradation of palm oil mill effluents (POME) was conducted to measure the discarded POME based on physicochemical quality. The bacteria that were isolated are Micrococcus species, Bacillus species, Pseudomonas species, and Staphylococcus aureus, while the fungi that were isolated are Aspergillus niger, Aspergillus fumigatus, Candida species, Fusa...
ABSTRACT Limited use of cereal straws in livestock feeding is due to their low voluntary intake, low protein contents and low digestibility. Nutritional value of these roughages can be improved through chemical, physical or biological methods. Efficacy of treating straw with urea for improving its nutritive value is considered equivalent to anhydrous or aqueous ammonia. However, the adoption rate of urea treatment by farmers is low, maybe due to relatively tedious technology and higher requ...
The electrophoretic resolution of DNA is carried out on a gel matrix of agarose or polyacrylamide. Agarose is used for horizontal electrophoretic procedure while polyacrylamide gel is used in vertical procedures. Agarose gels are used and cast by boiling agarose in a suitable dilute buffer, pouring into a mould and then allow it to solidify to form a matrix. The porosity of the formed matrix decreases with an increase in agarose concentration. When the DNA samples are loaded in an applied ele...
ABSTRACT The ineffectiveness of the strategies traditionally employed by science teachers has been attested to by several researchers. Thus research in science education has continued to seek for more effective ways of teaching science in general and biology in particular in order to ensure meaningful learning. Therefore, this study examined Senior secondary school students cognitive achievement in selected biology concepts using Mercedes model with embedded assessment strategies. The study a...
Abstract The thrust of this study was to determine the effects of explanations and integration of ideas on secondary school chemistry students' acquisition of observing and inferring skills in Lagos State of Nigeria. The extent to which gender could influence observing and inferring skills acquisition in chemistry was also ascertained. A null hypothesis was tested. The study adopted a quasi- experimental research design where intact classes were subjected to two treatment groups (explanation...
Abstract The study investigated the effect of the knowledge of Mathematics on Achievement of Physics students in secondary School in Lagos State. The study employed a pre-test, post-test control group quasi experimental research design, using school types and gender as moderator variables. A sample size of one hundred and ninety-four (J 94) Physics students were purposively selected from jive (5) senior secondary school (two Private, one Federal and two Public Senior Secondary School in Lago...
Abstract The new pathway for the synthesis of 2, 3-dichlorophenylpiperazine from cheap raw material, 2, 3-dichloroaniline is presented.
ABSTRACT This study evaluated the Integrated Science and Introductory Technology curricula contents as well as their implementation in secondary schools in Benue State. Twelve research questions were answered and six hypotheses tested in this study. The study employed a survey design and six instruments were used to collect data from 50 secondary schools selected from 246 schools in the State using the Probability Proportionate to Size (PPS) sampling technique, 10 experts each in the fields ...
ABSTRACT Small-scale mining has become an activity that provides livelihoods to growing numbers of rural people in Ghana. This has attracted most of the youth and other groups of people into the business. This study sought to explore the management of operations of small-scale mining industries in the Obuasi Municipality. The study sought the views of small-scale miners from the communities under study (Ahansoyewodea, Pomposo, Akrokerri, Kwabrafoso, Asonkori and Akaporiso) at Obuasi...
Abstract Learners play very significant roles in the teaching–learning process. Irrespective of how teachers teach, learners often have their own ways of learning. Three hundred senior secondary school II students selected from 10 senior secondary schools in Ilorin, Nigeria participated in the study. Simple random sampling technique was used to select 30 students from each of the 10 purposively sampled senior secondary schools. Data were collected using three instruments, namely, Chem...
ABSTRACT This study investigated the relationship between science process skills and student attitude toward physics in senior secondary school in Aliero metropolis. The study adopted a descriptive survey design and data were largely descriptive by nature. Two set of questionnaires namely; Science Process Skills Test (SPST) and Attitudes toward Physics Questionnaire (ATPQ) was used for Data collection constructed by the researcher. These were administered to a sample of 203 students selected ...
STEM is an acronym for science, technology, engineering and mathematics fields of study meant to improve U.S. competitiveness by guiding curriculum and influencing education policy. STEM education begins with K-12 educators, who are struggling with how to implement the Next Generation Science Standards (NGSS) that now place explicit emphasis on the relationship of engineering to science. The NGSS guidelines suggest that science curriculum should have activities with an iterative process invol...
Objective 3-D printing technologies have the potential to improve both Science, Technology, Engineering, and Mathematics (STEM) education and Career and Technical Education (CTE), as well as integrating these two educational emphases and providing opportunities for cross-curriculum engagement. The objective of this study is to investigate the potential of open-source (OS) technologies in an educational setting, given the combination of economic constraints affecting all educational environme...
