The objective of this paper is to evaluate the physicochemical characteristics a tropical seasonal water body- Ikoro stream, Edo State, Nigeria using standard methods. results obtained from physical and chemical analyses showed that range values were: 23oC - 30oC for air temperature, 22oC 29oC 1.28NTU 14.48NTU turbidity, 1mg/l 10mg/l total dissolved solid, 4.01 6.43 pH, 2.3µScm-1 21.7µScm-1 con...

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...

We describe the environment effects on the amount and quality of resources collected by Melipona rufi ventris Lepeletier in the Atlantic Forest at Ubatuba city, São Paulo state, Brazil (44o 48’W, 23o 22’S). Bees carrying pollen and/or nectar were captured at nest entrances during 5 min every hour, from sunrise to sunset, once a month. Pollen loads were counted and saved for acetolysis. Nectar w...

low- temperature (lt) tolerance is an economic trait in winter wheat that determines the plants’ ability to successfully cope with below freezing temperatures. to identify the genomic regions associated with lt tolerance in hexaploid wheat, an f2:3 population was produced from crossing between winter type and tolerant parent, mirnovoskaja 808 (lt50 = -20oc), and spring type and susceptible pare...

The roots of 7-d seedlings of two winter wheat cultivars differing in frost resistance were used to study changes in lectin activity using the inhibitor of microtubule polymerization oryzalin (15 μM) in unhardened (23oC) and hardened (2–3oC, 3–7 d) plants. Plants were grown with the antagonist of calmodulin, chlorpromazine (250 μM) or without chlorpromazine in medium. It was shown that the dyna...

background: in the recent years, there has been an increasing interest in secretory production of recombinant proteins, due to its various advantages compared with intracellular expression. signal peptides play a critical role in prosperous secretion of recombinant proteins. accordingly, different signal peptides have been assessed for their ability to produce secretory proteins by trial-and-er...

Empty Fruit Bunches (EFB) are oil palm waste that has the potential as a source of bioenergy because it contains lignocellulose (cellulose, hemicellulose, and lignin) so can be converted into biofuel through thermal cracking, adsorption, distillation processes. Thermal cracking is decomposition chemical content biomass by utilizing heat without mixture oxygen at temperature 200oC–600oC. This st...
