本文探讨了营运资金管理对企业绩效的影响。营运资金通常是指完成常规紧急任务所需的资金。本文的目的是衡量组织的营运资金水平和组织盈利能力,并检验营运资金管理与组织盈利能力之间的关系。在营运资金管理方面,按资产和负债划分的营运资产多于流动负债。营运资金管理（WCM）是一个在短期财务管理中争论不休的问题,是一个复杂的公司财务决策问题,对公司收益和流动性有重要影响。本文采用了回归分析和相关分析的方法,检验企业绩效对营运资金的影响。其中,二级数据来自于在巴基斯坦和中国注册的公司的年报。本文分析表明,信贷周转率对资产收益率的影响成反比,但影响并不显著。存货周转率对资产报酬率有显著的正向影响,另一方面,当这项研究的结果涉及从巴基斯坦抽取的样本时,信贷比率与资产收益率呈正相关。中国信贷周转率与资产收益率呈显着正相关,库存周转率与资产收益率也呈正相关。在巴基斯坦水泥行业,CR对ROA有显著的积极影响。DTO对ROA也有显著的积极影响。本文提出的建议:对于正常的业务规划,管理者必须确定什么是最适合公司需要的最有效的资本结构。管理人员往往低估周转金管理,而且,作为一项规则,着眼于长期投资。多年来,营运资金管理一直被忽视,因为与利润增长相比,要改变短期政策需要付出相当大的努力。

Implication of neurohormonal-coupled mechanisms of gastric emptying and pancreatic secretory function in diabetic gastroparesis

World Journal of Gastroenterology 2018年第34期24卷 3821-3833页

Recently, diabetic gastroparesis(DGP) has received much attention as its prevalence is increasing in a dramatic fashion and management of patients with DGP represents a challenge in the clinical practice due to the limited therapeutic options. DGP highlights an interrelationship between the gastric emptying and pancreatic secretory function that regulate a wide range of digestive and metabolic functions, respectively. It well documented that both gastric emptying and pancreatic secretion are under delicate control by multiple neurohormonal mechanisms including extrinsic parasympathetic pathways and gastrointestinal(GI) hormones. Interestingly, the latter released in response to various determinants that related to the rate and quality of gastric emptying. Others and we have provided strong evidence that the central autonomic nuclei send a dual output(excitatory and inhibitory) to the stomach and the pancreas in response to a variety of hormonal signals from the abdominal viscera. Most of these hormones released upon gastric emptying to provide feedback, and control this process and simultaneously regulate pancreatic secretion and postprandial glycemia. These findings emphasize an important link between gastric emptying and pancreatic secretion and its role in maintaining homeostatic processes within the GI tract. The present review deals with the neurohormonal-coupled mechanisms of gastric emptying and pancreatic secretory function that implicated in DGP and this provides new insights in our understanding of the pathophysiology of DGP. This also enhances the process of identifying potential therapeutic targets to treat DGP and limit the complications of current management practices.

Downhill Zagreb Topological Indices and <i>M<SUB>dn</SUB></i>-Polynomial of Some Chemical Structures Applied for the Treatment of COVID-19 Patients

Open Journal of Applied Sciences 2021年第4期10卷 395-413页

A graphical index is a numeric value corresponding to a graph which is structurally invariant and in molecular graph theory these invariants are known as topological indices. In the field of Chemical and Medical Sciences, the topological indices are used to study the chemical, biological, medical and pharmaceutical features of drugs. With reference to the previous deadly diseases, the COVID-19 pandemic has considered to be the biggest life threatening issue that modern medicines have ever tackled. COVID-19 is immedicable and even the existing treatments are only helping the certain group of sufferers. Scientists have tested available antiviral agents and got a favorable impact on recovering from pandemic. Some of these antiviral agents are remdesivir, chloroquine, hydroxychloroquine, theaflavin and dexamethasone. Keeping in view of the importance of topological indices in the study of pharmaceutical and chemical drugs, in this paper, we calculate the Mdn-Polynomial, some downhill Zagreb topological indices and some downhill Zagreb polynomials of some of the anti viral agents remdesivir, chloroquine, hydroxychloroquine, theaflavin and dexamethasone. The results thus obtained may be useful for the finding new medicine and vaccine for the treatment of COVID-19.
