/in /by

In this paper, the origin of the Hui people in China is researched, the formation history of the Hui people is stated in detail, the development and evolution of the Hui people are described in detail, and the origin, formation, development and evolution history of the Hui people are divided into six stages, and the characteristics of each stage are analyzed in detail. It is pointed out that the origin of Hui nationality originates from the opening of China’s Silk Road, the needs of Sino-foreign economic and trade development, and China’s political integrity, economic prosperity, cultural prosperity, national prosperity and people’s security are closely related. The formation of Hui in China has the great attraction of Sui, Tang and Song dynasties, and is closely related to the expansion, wars and killings of Islam in the Arab Empire and the plunder, capture and recruitment of soldiers in the Mongolian and Yuan Dynasties. The formation of the Hui people and the essence of its development and growth are the fundamental way for the eastern Muslims to settle and grow in China and absorb the blood of Han Chinese, Mongolians, Uyghurs, Jews and other ethnic groups.

Laboratory Investigation on Enhanced Oil Recovery Using Local Alkaline –Polymer for Niger – Delta Region

/in /by

Approximately sixty percent of crude oil still lay trapped in the reservoir even after primary and secondary recovery processes have been completed, hence the need for a method that further improves recovery. To increase oil recovery and encourage utilization of local content, locally source alkaline and polymer materials were used to improve oil recovery in this study. The local alkaline and polymer used are plantain peel ash and corn starch respectively. The efficiency of the plantain peel ash and corn starch solution were tested using different seven core samples. The core samples were individually flooded with brine (salt and water) for secondary recovery process and different concentrations of plantain peel ash and corn starch both in stand-alone and in combined form were used for tertiary recovery. The results obtained from the experimental work showed that sample-B5 with 0.2g of plantain peel ash and 0.2g of corn starch in 100ml of brine gave the highest cumulative recovery of 86% as to compare to samples B1 and B2 which has the cumulative recovery of 70% and 78% respectively. Sample-B7 which has the highest concentration of corn starch (0.4g/100ml) gave the lowest recovery of 65% due to polymer adsorption on the rock surfaces which alters the rock wettability. The assessment of formation damage was done by evaluating and determining the permeability change after tertiary flooding. The concentrations with plantain peel ash have reduced permeability change. These locally sourced materials can replace synthetic enhanced oil recovery (EOR) chemical when properly modified and refined, and they are also cheap and environmentally friendly.

 

A Review of Analytical Methods on Carbamazepine an Antiepileptic Drug

/in /by

Carbamazepine is used to control and treat bipolar 1 disorder’s acute manic and mixed episodes, trigeminal neuralgia, and epilepsy. Generalized tonic seizures (grand mal), mixed seizure patterns, and partial seizures with complicated sympatomatology (psychomotor, temporal lobe) are the only indications for epilepsy. Trigeminal neuralgia or tic douloureux are first-line conditions for which carbamazepine is FDA-recommended. In individuals with acute manic or mixed episodes of bipolar 1 mania, a comprehensive evaluation demonstrates the effectiveness of carbamazepine extended release. Carbamazepine is contraindicated in patients with bone marrow depression and hypersensitivity to this drug or tricyclic compounds such as amitriptyline. Dizziness, sleepiness, ataxia, nausea, and vomiting are some of the most typical adverse effects of carbamazepine. With the ability to penetrate the placenta and pass through breast milk in nursing infants, carbamazepine necessitates a choice between stopping the medication in the mother or stopping nursing. Different analytical techniques developed and validated as per ICH guidelines for the determination of carbamazepine, including High performance liquid chromatography (HPLC), Ultra performance liquid chromatography (UPLC), mass spectrometric, Liquid chromatography-Mass spectroscopy (LC-MS), and UV-Spectrophotometry has been explained in this article as it is important to analyze the drug content and % purity  in bulk and Pharmaceutical formulations for quality control purpose.

The Interrelationship between Economic Growth and Tax Revenues in Cambodia

/in /by

The relationship between economic growth and the growth rate of tax revenues on goods and services, tax revenue on income, profit, and capital gain, and tax revenue on international trade and transaction was analyzed using a VAR model. All variables in this study were found to be integrated of order one, therefore the model was run using first differences. The lag length of the model was determined to be optimal at lag-two based on the information criterion. The estimated results of the model successfully passed all diagnostic tests, including tests for residual normality, serial correlation, and heteroscedasticity. Since all the inverse roots of the AR characteristic polynomial were within the unit circle, the model was deemed stable. The empirical findings from the VAR model indicated that the growth rate of tax revenue on income, profit, and capital had the most significant impact on economic growth, ranging from 2.3505% to 2.7155%. This was followed by tax revenue on goods and services, ranging from 0.5776% to 0.5954%, and tax revenue on international trade and transaction, ranging from 0.2747% to 0.5930%. Furthermore, the response of the growth rate of all tax revenues to changes in the economic growth rate exhibited a cyclical pattern around its mean.

The Effects of Case Study Teaching on Learners’ Critical Thinking Skills in Physical Sciences Classrooms

/in /by

The aim of the study was to investigate the effects of case study teaching on learners’ critical thinking skills in Grade 10 Physical Sciences classrooms. A non-equivalent (pre-test and post-test) control-group quasi-experimental design was adopted for the purposes of this study. The sample consisted of 122 learners from four schools (70 learners from two rural – 29 for experimental group and 41 for control group) and 52 from two urban schools (30 experimental group and 22 control group). A multistep sampling process was implemented in selecting the participating schools. Two schools were treated as the experimental groups and the other two as control groups. The intervention in the experimental group was case study teaching, while in the control group the traditional lecture method was implemented. The results of this study indicated that case study teaching improved learners’ critical thinking skills and that the urban learners’ critical thinking skills improved three times more than that of their rural counterparts. The results also indicate that there is no significant difference in the way case study teaching improved the critical thinking of the female participants compared to how it improved that of their male counterparts.

Comparing Solar Heater Designs: Evacuated Tube Vs. Flat-Plate Collectors

/in /by

In terms of solar heater designs, this study compares the characteristics of collectors made from evacuated tubes (ETCs) as well as collectors with flat plates (FPCs). Due to their reduced heat loss, ETCs—which have individual tubes made of glass with a sealed under-vacuum double-wall design—perform exceptionally well in colder climates. FPCs, in comparison, are more affordable but less effective since they include a simpler absorbent plate that fits inside of a flat panel. These designs can be implemented using the SolidWorks software, which permits precise 3D modeling as well as simulations. According to research, ETCs are appropriate for colder locations since their vacuum insulation reduces heat loss along maintains greater temperatures. Even while radiation losses make FPCs less efficient, they are still excellent at collecting daylight energy, specifically in warmer climates. Decision-makers looking for sustainable cooling solutions might benefit from analysis that takes into account technical characteristics, financial viability, and geographical compatibility.

Social Support to Increase Adherence of People Living with HIV in Antiretroviral Treatment (Literature Review)

/in /by

Antiretroviral medication (ART) therapy is the primary method of managing HIV-positive patients. The primary factor leading to therapeutic failure is nonadherence to ART therapy. Personal traits (predisposition), availability to health information, and social support, can be linked to adherence throughout ART therapy. Through a review of the literature, we hope to learn more about how social support can improve People Living With HIV (PLHIV) patients’ compliance with ART treatment. The literature review method is employed in this research strategy. The search for articles turned up 14 articles from 2019 to 2023 that were relevant to the issue. Various sources can be used to provide social assistance. Social support from friends, family, and medical professionals has a significant impact on PLHIV compliance with taking ART. Peer Support Groups (KDS) play a function in preserving adherence to ART treatment in PLHIV in addition to family support. Peer support groups offer assistance in the form of knowledge about sickness and treatment as well as inspiration to continue taking antiretrovirals religiously in order to survive. Numerous journals demonstrate a link between different types of social support and medication adherence. There is something, nevertheless, that is inversely related to the study. Social support will, nevertheless, have a favorable effect on treatment adherence. It is impossible to increase social support from a single source. However, if it can work in concert with social support, it will be ideal. To get the best outcomes, namely treatment adherence to antiretroviral therapy, it is vital to develop positive relationships amongst sources of support. Medication adherence is also influenced by internal variables, such as knowledge and the desire to preserve health, in addition to external support factors.
