Although tools exist to aid practitioners in the construction of directed graphs typified by Conceptual Graphs (CGs), it is still quite possible for them to draw the wrong model, mistakenly or otherwise. In larger or more complex CGs it is furthermore often difficult–without close inspection–to see clearly the key features of the model. This paper thereby presents a formal method, based on the ...

Ports are important hubs that have positive impacts on the regions they serve, but also pose some challenges need to be addressed. Many ports around world aligned their development strategies with concept of green growth; however, and efficient performance does not only depend port management itself; elements negotiated approved by local national governments. One such is road access. We investi...

Although there are conflicting results on whether adenosine infusion during reperfusion alters infarct size, there are several reports that indicate adenosine A(2a) agonists reduce infarct size. There are also reports that the A(2a) agonist CGS-21680 increases cAMP and contractility in ventricular myocytes. The purpose of this study was to determine whether low-dose intracoronary infusions of C...

The purpose of this study was to investigate changes in the periodontal masseteric reflex (PMR) after experimentally induced occlusal hypofunction. Wistar rats were divided into control groups (CGs) and hypofunction groups (HGs). Rats in the HGs had their lower incisors cut down every other day for 6 weeks. Electrical stimulation was given to the periodontal ligaments of an upper incisor or the...

Background: The pathophysiology of the varicocele has received considerable study, both in humans and in animal models. The sperm DNA damage and related oxidative stress have been identified as significant cause of male infertility. Present study was designed to evaluate the testicular nitric oxide (NO) generation, lipid and carbonyl groups (CGs) peroxidation and to analyze related sperm DNA da...

Many nations are adopting smart city applications, which boost residents’ satisfaction with their living conditions and reduce pollution by better-using people’s time resources. Multi-Location parking garages standard in cities because they allow for better access control space allocation to avoid traffic delay complex business areas. The Internet of Things (IoT) has the potential link billions...

The conjugate gradient squared CGS algorithm is a Krylov subspace algorithm that can be used to obtain fast solutions for linear systems Ax b with complex nonsymmetric very large and very sparse coe cient matrices A By considering electromagnetic scattering problems as examples a study of the performance and scalability of this algorithm on two MIMD machines is presented A modi ed CGS MCGS algo...

In this paper, a simple index for evaluating the economics of cogeneration systems (CGS) is first derived. Second, various strategies to improve the economics of a CGS is generally discussed. Finally, the impacts of the change in various factors determining the economics of a CGS are investigated, by taking a CGS composed of gas turbines and a waste heat boiler for district heating and cooling ...

Problem: Planners, politicians, organizations, and citizens in many cities recognize community gardens as a vital part of urban food production. To fulfill community or organizational goals, it is helpful to systematically identify and assess urban vacant land that could be used as potential garden sites. Purpose: The technical purpose of this project was to demonstrate how stakeholder input co...

background :adenosine is an endogenous purine nucleoside that has a neuromodulatory role in the central nervous system. the amphetamine derivative (±)-3,4-methylenedioxymethamphetamine (mdma or ecstasy) is a synthetic amphetamine analogue used recreationally to obtain an enhanced affiliated emotional response. mdma is a potent monoaminergic neurotoxin with the potential of damage to brain neuro...
