Information sources of knowledge based economic development for fisheries in Turkey

African Journal of Agricultural Research

Afr. J. Agric. Res.

Fishery is a very important sector in Turkey due to economic, geographic, traditional, and cultural conditions. The sector has being one of the four sub-sectors of the agriculture till recent year when the Ministry of Food, Agriculture, and Livestock separate Fishery as an independent sector. The coastal areas, the amounts of lakes and rivers have been very important for fishery supplies in Turkey. Although Turkey has big potential fishery sector,... Read more

Demographic and microbiological profile of cystic fibrosis in Durban, South Africa

African Journal of Microbiology Research

Afr. J. Microbiol. Res.

Cystic fibrosis (CF) necessitates long-term treatment with multiple antibiotics creating selection pres-sure for the development of antibiotic resistance in infecting and/or colonizing organisms, impacting on disease management, morbidity and mortality. Sputum samples were obtained from patients attending the only two CF clinics in Durban over a year. The patient demographics and clinical data were recorded. Bacterial isolates were subjected to...

Analysis and evaluation of differential inductive transducers for transforming physical parameters into usable output frequency signal

International Journal of Physical Sciences

Int. J. Phys. Sci.

This paper presents a novel hybrid oscillating inductive sensor circuit converting deflection oscillations into useful signal and thus being used to support an oscillatory circuit mechanism and management of their resulting oscillation in a real-time implementation. This circuit does not only detects and optimizes the deflections produced in an oscillation in instrumentation electronics, but also provide an improved sensory with high accuracy,... Read more
