Production logging

Bài thuyết trình Production logging & IPM Mbal được thực hiện với mục tiêu nhằm xác định tính chất tự nhiên và các ứng xử của chất lưu trong và xung quanh giếng trong quá trình khai thác hay bơm ép để kiểm soát các thông số ở mức ổn định (cho dòng ra ổn định, chống các vấn đề trong lúc khai thác như rò rỉ, mất áp,...); chẩn đoán các vấn đề xảy ra trong lúc khai thác như rò rỉ, mòn ống, hoặc crossflow (tình trạng xi măng ống chống);...

This history of antimicrobials is marked with impressive discoveries, the majority of which have their origin in natural products. However in this work, the antimicrobial activity of β- nitrostyrenes and related compounds of synthetic origin is reviewed and investigated with a particular focus on the influence of fluorine functionality. Various fluorinated β-methyl-β-nitrostyrene compounds were prepared, their minimum inhibition concentration in cultures of Gram positive, Gram negative and a fungus and their lipophilicity was determined.

Deproteinated cheese whey was used for biomass production of probiotic strain Lactobacillus helveticus MTCC 5463 in a biofermenter. Optimization of growth parameters such as temperature, pH and time of incubation as well as nutrient supplementation of cheese whey was carried out using response surface methodology (RSM). Cheese whey supplemented with 0.95% yeast extract and 0.95% proteose peptone, inoculated with 6% (v/v) active culture of L. helveticus MTCC 5463 and fermented for 24 h at optimized temperature of 40ºC and pH 6.25 yielded 3.25 g/L dry cell biomass and 14.

We show that every subset of SL2 (Z/pZ) grows rapidly when it acts on itself by the group operation. It follows readily that, for every set of generators A of SL2 (Z/pZ), every element of SL2 (Z/pZ) can be expressed as a product of at most O((log p)c ) elements of A ∪ A−1 , where c and the implied constant are absolute. 1. Introduction 1.1. Background. Let G be a finite group. Let A ⊂ G be a set of generators of G. By definition, every g ∈ G can be expressed as a product of elements of...
