The main objective of this research is to study the effects of JP-4-biodiesel-diesel fuel blends and operating parameters on the emission characteristics of a CI engine. The experimental tests were performed on a four-cylinder DI diesel engine. The Mixture-RSM method was used to develop mathematical models based on experimental data. The results showed that with the increase of the biodiesel pr...

The main aim of this research is to assess the performance risk-appetite discriminated investors in PSX listed fertilizers industry, using RSM and non-RSM, maximize their portfolios' wealth. period (18 November 2015-June 30, 2021) well characterized by presence two distinct volatility-related bull-regime bear-regime, it divided into groups: in-sample out-sample. Throughout out-sample time, diff...

Traditionally, optimization in biological analyses has been carried out by monitoring the influence of one factor at a time; this technique is called one-variable-at-a-time. The disadvantage of this technique is that it does not include any interactive effects among the variables studied and requires a large number of experiments. Therefore, in recent years, the Response Surface Methodology (RS...

Kitchen wastes containing high amounts of carbohydrates have potential as low-cost substrates for fermentable sugar production. In this study, enzymatic saccharification of kitchen waste was carried out. Response surface methodology (RSM) was applied to optimize the enzymatic saccharification conditions of kitchen waste. This paper presents analysis of RSM in a predictive model of the combined ...

The threshing of frozen corn is accompanied by breakage and adherence, which influence the cleaning performance when corn-cleaning mixture separated cleaned. In order to reduce impurity ratio loss during provide theoretical support for combine harvesting, this study employed a self-made air-screen system with adjustable parameters. optimal process parameters were determined using response surfa...

Statistical analysis techniques Experiment Design (ED) and Response-Surface-Method (RSM) have traditionally been employed to conduct and analyse real-world experiments. ' ED and RSM provide a systematic and efficient framework for conducting a minimum number of experiments while gaining a maximum amount of information from the experimental results. Recently, ED and RSM have been applied to comp...

In schistosomiasis mansoni, hepatic granulomatous inflammation surrounding parasite eggs is mediated by CD4(+) T helper (Th) cells sensitized to schistosomal egg antigens (SEA). We previously showed that a prominent lymphoproliferative response of CD4(+) Th cells from schistosome-infected C57BL/6 (BL/6) mice was directed against a 62-kDa component of SEA. A partial amino acid sequence of the 62...

48 The mucosal gene expression in rectosigmoid mucosa (RSM) in irritable bowel syndrome 49 with diarrhea (IBS-D) is unknown. Our objectives were: first, to study mRNA expression (by 50 RT PCR of 19 genes pertaining to tight junctions, immune activation, intestinal ion transport 51 and bile acid homeostasis) in RSM in IBS-D patients (n=47) and healthy controls (n=17) and 52 study expression of a...
