Penelitian yang dilakukan adalah injeksi surfaktan, dimana surfaktan di pilih AOS menggunakan konsentrasi rendah untuk menaikan produksi minyak. Penggunaan tersebut bertujuan menurunkan interfacial tension atau tegangan antarmuka pada dua fluida, yaitu minyak serta air, sehingga dapan keluar dari pori-pori batuan reservoir. Pada penelitian ini digunakan salinitas sebesar 5000 ppm, dan 20000 ppm...

Seed priming has proved to be an effective pre-germination seed invigoration technique for different crops improve and seedling performance under abiotic stresses. In Bangladesh, winter rice is very often exposed cold waves just after sowing in the nursery bed resulting poor germination emergence, yellowish thin seedlings production, a low survival rate. may mitigate stress during emergence hel...

Sequential quadratic programming (SQP) methods have proved highly effective for solving constrained optimization problems with smooth nonlinear functions in the objective and constraints. Here we consider problems with general inequality constraints (linear and nonlinear). We assume that first derivatives are available and that the constraint gradients are sparse. Second derivatives are assumed...

The cupin family comprises a family of proteins possessing a common beta-barrel structure that is thought to have originated in a prokaryotic ancestor. This structural motif is found as a single domain in fungal spherulins, fern sporulins and the germins/oxalate oxidase proteins of plants, while the globular storage proteins of plants, called legumins (11 S) and euvicilins (7 S), are two-domain...

The interference of some specific aqueous two-phase system (ATPS) phase-forming components in bovine serum albumin (BSA) determination by the Bradford method was investigated. For this purpose, calibration curves were obtained for BSA in the presence of different concentrations of salts and polymers. A total of 19 salts [Na₂SO₄, (NH₄)₂SO₄, MgSO₄, LiSO₄, Na₂HPO₄, sodium phosphate buffer (pH 7.0)...

Cotton is one of the most important fibre plants with much more products being manufactured from it than most other fibre . Apart from fibre, it is used for explosives, cottonwool, etc, and the seed is used principally for the manufacture of oil, soap, animal feed and fertilizers, producing practically no waste. To determine the effective sawdust concentration to inhibit the growth of Rhizocton...

The present study was aimed at evaluating effects of malathion on the various reproductive parameters, namely, egg mass weight (EMW), reproductive index (RI), percentage inhibition of oviposition (%IO), and hatchability percentage of eggs of Rhipicephalus (Boophilus) microplus (Canestrini 1887) females from 19 districts of Punjab, India. The effect on various parameters was found to be dose dep...
