Optimization of hydraulic retention time (HRT) employing statistical tools of a lab-scale sequencing batch rector (SBR) treating real wastewater of a University campus – JBES

treating real wastewaterBy: Ghalib Hasnain

Abstract

Two lab-scale sequencing batch reactors (SBR) with combined capacity of 45 L/day, each having holding volume of 6 L were installed and operated at Institute of Environmental Sciences and Engineering (IESE) lab. The SBR systems were automated for variable hydraulic retention time (HRT) to treat real university wastewater (average COD = 220 mg/L). Continue reading

Pollination and yield components of Physalis minima (Solanaceae) as affected by the foraging activity of Apis mellifera (Hymenoptera: Apidae) and compost at Dang (Ngaoundéré, Cameroon) – IJAAR

Physalis minimaBy: Jackson Dapsia Djakbé

Abstract

This research was conducted to assess the interactions between compost and honeybee on P. minima yields in the field from April to August 2015 and 2016 at Dang. A total of 600 and 540 flowers were labeled in 2015 and 2016 respectively, then divided into twelve treatments each year, differentiated according to whether subplots were applied with compost, chemical fertilizer or not, flowers were protected from insect activities or not, flowers were protected then opened only to A. mellifera or closed without insect visits.

Evaluation of selected tomato cultivars reaction to infestation with Meloidogyne javanica in greenhouse conditions – IJAAR

Meloidogyne javanicaBy: M.W. Mwangi

Abstract

Root-knot nematodes are the most important phytoparasites that decrease tomato production in Kenya. It is important to test susceptibilities of tomato cultivars to root-knot nematodes (RKN) in order to mitigate against losses, by putting in place appropriate control measures. Continue reading

Investigations on the antimicrobial potential of Abutilon fruiticosum Gill & Perr. – JBES

Abutilon fruiticosumBy: Suraya Mushtaq

Abstract

The present study is an investigation on the antibacterial and antifungal activity of the extracts of ethno botanically important plant Abutilon fruiticosum Gill & Perr. in different polar and non-polar solvents. The zone of inhibition and minimum inhibitory concentration (MIC) were recorded against four different bacterial (Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa) and two fungal strains (Aspergillus niger, Aspergillus oryzae).
