The physicochemical parameters of groundwater at Auchi and South-Ibie were investigated to determine underground water quality in this environment. Water sampled locations categorized as Iyekhei (Iyekhei), Poly (Auchi PW), Hostel PH), Double Delight (DDH); are Levis Gas Plant (LGP), Pastoral Centre (PC), Global Castle Sawmill Road (GCHS), Arsenal and, Lagos Street (AHLS). A total number 80 samp...

background: natural organic matter is the cause of many problems associated with water treatment such as the presence of disinfection by-products (dbps) and membrane fouling during water filtration. in this study, the performance of the peroxi-electrocoagulation process (pep) was investigated for the removal of humic acids (has) from aqueous solutions. methods: pep was carried out for the remov...

laboratory and greenhouse experiments were conducted to determine the effects of drought and salinity stress, temperature, ph and soil depth on rye germination and emergence in gorgan university of agricultural science and natural resources. optimum temperature for germination between 25 to 34.51   oc and base and ceiling temperatures were estimated as 3.3 and 40   oc, respectively. this volunt...

This study evaluated the use of an anaerobic packed-bed reactor for hydrogen production at different hydraulic retention times (HRT) (1-8 h). Two reactors filled with expanded clay and fed with glucose (3136-3875 mg L(-1)) were operated at different total upflow velocities: 0.30 cm s(-1) (R030) and 0.60 cm s(-1) (R060). The effluent pH of the reactors was maintained between 4 and 5 by adding Na...

The Physical and chemical quality of natural water is essential for the life aquatic organisms. This study was aimed at investigating physical parameters eight (8) local swamp ponds in freshwater Engenni. were monitored over a period three months (February-April 2019), During this period, Temperature (℃), Dissolved Oxygen (DO, mg/l), pH, Electrical Conductivity (EC:µs/cm), Total dissolved solid...

BACKGROUND The diagnosis and monitoring of severe combined immunodeficiency disease (SCID) attributable to adenosine deaminase (ADA) deficiency requires measurements of ADA, purine nucleoside phosphorylase (PNP), and S-adenosyl-L-homocysteine-hydrolase (SAHH) activity and of deoxyadenosine metabolites. We developed capillary electrophoresis (CE) methods for the detection of key diagnostic metab...

When unilamellar vesicles are prepared in the presence of 3-Palmitoyl-7-ocy-coumarin abbreviation 3P-UBF) this lipoid pH-Indicator is anchored by its fatty acid chain to the membrane and can be used to measure pH-changes at the outer and inner membrane surface (ranging from pH to pH 9.5). By rapidly changing the pH of the outer aqueous phase a pH-gradient is set up across the vesicle membrane. ...
