Vast financial investments have been made in the upstream crude-oil and natural-gas (CONG) sector in Nigeria, but have not resulted in significant benefits for most Nigerians. The associated major activities e.g. exploration, drilling, production, well intervention and service provision remain primarily controlled and managed by foreign multinational companies. Only minor contracts have been awarded to local contractors. Several factors, ranging from locally inadequate finance being available, corrupt local operators, lack of technical expertise and the conflicting attitudes of multinational operators and local contractors have contributed to this. Yet, numerous opportunities are increasingly available for indigenous entrepreneurs and local contractors. To achieve good public relations, sustainability and better economic performances, a wiser balance between globalisation and localisation is needed! This study considers the impedances to achieving greater indigenous inputs to the CONG sector, with recommendations proffered with respect to what could be done to alleviate them.
The whole set of genetic material of a species of plants is known as germplasm of the organisms. Through various breeding techniques the germplasm of various plant species can be stored or preserved for future plant development. The techniques of gerplasm preservation vary from cryopreservation, slow growth cultures, DNA clones, in-vitro storage, cold storage, super cold storage, field preservation to the use of artificial seeds. The major purpose of germplasm preservation is to preserve rare and endangered species of plants around the globe for future propagation and development; hence germplasm is the foundations of agricultural productions. Today's preservation techniques have been developed on the base of natural occurring phenomena like sporulation, germination, hibernation and adaptation which are found in different animals and in micro organisms. All the simple and sophisticated preservation techniques are today being used in giant projects that are on going.
The bacteriological assessment of indoor air of the male hostel at Rhema University Nigeria was undertaken in this study. Bacteriological analyses of Air samples from male hostels was carried out weekly for 4 weeks using standard microbiological methods in June, 2021 to determine their bacteriological content. Data obtained was analyzed using descriptive statistics and presented in tables. The result showed that the concentration of bacteria isolates increased as the duration of exposure of the media increased. The highest bacteria concentration was seen at room 205 at 40 minutes (29.8 x 102CFU/M3) and the least at room 204 at 20 minutes (0.9 x 101 CFU/M3). The concentration of bacteria at other rooms were room 305 at 40 minutes (17.7 x 102 CFU/M3), room 304 at 20 minutes had 1.3 x 101 CFU/M3, room 405 at 40 minutes had 17.8 x 102 CFU/M3, room 404 at 20 minutes had 3.6 x 101 CFU/M3, room 504 at 40 minutes had 17.6 x 102 CFU/M3 and room 503 at 20 minutes had 11.9 x 102 CFU/M3. A total of eleven (11) different bacteria species were isolated and identified as Staphylococcus aureus (100%), Escherichia coli (75%), Staphylococcus epidermidis (75%), Klebsiella spp (75%), Bacillus subtilis (75%), Streptococcus pyogenes (50%), Bacillus megaterium (50%), Bacillus cereus (50%) and Serratia marcescens (25%). Staphylococcus aureus is the most occurring bacteria specie (100%) while Serratia marcescens is the least occurring bacteria specie (25%). Potential pathogenicity testing of isolates revealed Staphylococcus aureus, Bacillus cereus and Streptococcus pyogenes as potential pathogenic species found in the hostel rooms. Bearing in mind that some of the bacteria species isolated showed potential pathogenic abilities, it means that the air quality of the male hostel rooms may have health implications. There is therefore need for periodic air quality evaluation in the male hostel to discover and manage those environmental variables which favours the multiplication of bacteria. Students are advised to implement good sanitation and hygiene practices to improve indoor air quality in the hostels and prevent possible infection or disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
