Arboricity And Span In Fuzzy Chromatic Index

A fuzzy matching is a set of edges in which an edge does not incident on a vertex with same membership value. If every vertex of fuzzy graph is M-Plunged then the fuzzy matching is called as fair fuzzy matching. In this chapter, fuzzy coloring and fuzzy chromatic index are defined. The concept of Arboricity and span in fuzzy chromatic index are discussed in detail. Some theorems based on these concepts are proved

ANALYSIS OF BULK ARRIVALS IN QUEUEING MODELS

       Present paper surveys the literature on bulk queueing models. The concept of bulk arrivals and bulk services has gained a tremendous significance in present situations. Due to congestion problem everywhere (banks, metro stations, bus stops, railway reservation, traffic … etc.) researchers have to focus their attention to develop models and mechanism to deal with the same. A number of models have been developed in the area of queueing theory incorporating bulk queueing models. These bulk queueing models can be applied to resolve the congestion problems. Through this survey, an attempt has been made to review the work done on bulk queues, modeling various phenomenons. The goal is to provide sufficient information to analysts, managers and industry people who are interested in using queueing theory to model congestion problems and want to locate the details of relevant models

Effects of concurrent TeO2 reduction and ZnO addition on elastic and structural properties of (90 − x)TeO2–10Nb2O5–(x)ZnO glass

Niobium-containing tellurite glass with starting composition of (90 − x)TeO2–10Nb2O5–(x)ZnO (x = 0–15 mol%) have been prepared by melt-quenching method and the effect of reduction of TeO2 with simultaneous increase in ZnO on elastic properties was studied. Ultrasonic longitudinal and shear velocity showed initial decrease of 3.52% and 2.37%, respectively, at x = 5 mol%. For x > 5 mol%, longitudinal velocity showed weak recovery but shear velocity showed steady recovery with ZnO and recorded 0.95% increase in value at x = 15 mol% compared to x = 0 sample. Shear and Young's moduli recorded similar drop at x = 5 mol% followed by strong recovery at x > 5 mol%, while longitudinal and Bulk modulus showed weak and no recovery, respectively, with x. Infrared (IR) absorption spectra showed increase in intensity of NbO6-assigned peak accompanied by increase in intensity of ZnO4 tetrahedra and TeO4 trigonal bipyramid (tbp) assigned peaks indicating formation of both non-bridging oxygen, NBO and bridging oxygen, BO, respectively, with addition of ZnO. The initial drop in ultrasonic velocity and related elastic moduli observed at x = 5 mol% indicates weakening of network rigidity of the glass system due to structural modification as a direct effect of TeO2 reduction and existence of NBO. However, further replacement of TeO2 by ZnO at x > 5 mol% contributed to increase in BO causing rigidity of the glass network to improve. In addition, hardness, H, was observed to increase with ZnO indicating increase in connectivity of the glass network while Poisson's ratio, σ, decreased indicating increase in cross-link density of the glass system. The combined results of ultrasonic velocity and IR absorption spectra suggest that the role of TeO2 is very critical in the ternary glass system as, although ZnO addition showed improved rigidity due to recovery of shear modulus, the weakening of longitudinal and Bulk moduli indicates ZnO is not fully effective as glass former in place of TeO2

Neutrosophic bipolar vague binary topological space

In this paper, we make an interesting connection between the mathematical approaches to vagueness and the bipolar binary set. The concept of bipolar binary sets over two universal sets. To eliminate ambiguity in a data set, bipolarity is primarily introduced in imprecise binary sets. This article's main objective is to familiarize the reader with the novel concept of a neutrosophic bipolar vague binary set. We also discuss operations like ‘union’, ‘intersection’ and ‘complement’. The concepts of neutrosophic bipolar vague binary topology, zero, unit, open and closed set, neutrosophic bipolar vague binary ‘????-open’ and ‘????-closed’ sets are introduced and their properties are also discussed. Furthermore, the neutrosophic bipolar vague binary ‘b-interior’ and ‘b-closure’ set are defined. Theorems related to these concepts are stated and proved

Automatic materials tracking practices through RFID implementation in construction projects

Materials tracking for materials management play a vital role and contributed a major portion of the total cost in a construction project. In addition, the improper handling and storage of materials at the construction site has made it difficult to track and locate at the time are needed to carry out construction works. These problems subsequently contribute to the project delays and increase in the total project costs. Thus, this paper seeks to identify problems regarding current material tracking practices in materials management processes. In this paper, ICT and potential implementation of Radio Frequency Identification (RFID) for automatic materials tracking is also scrutinised. Data for this paper was obtained from the literature review and the case studies conducted in several construction projects. Semi-structured interviews with construction practitioners were carried out in order to gain insights into current problems, information and communication technologies (ICT) implementation, and RFID capability in assisting materials tracking practices. This paper reveals that construction projects in Malaysia are still using manual materials tracking practices, basic ICT implementation, and totally none RFID existence. Thus, there is a need for the application of RFID in order to facilitate materials tracking automatically for enhancing construction industry processes through IR 4.0

Spice Foods effects on Body Weight Reductions between Obese Animal Models

The aim of this study was determination and identification of phenolic and flavonoids fraction in addition to the antioxidant activities of used herbals (curcumin, black pepper and cumin) by HPLC in addition to evaluating the effects of such different spicy food consumptions on body weight reduction between obese animal models. Rats were randomly divided to ten groups fed; Black Papers, Cumin and Curcumin either alone or in different mixtures additionally to groups fed Orlistat (control body weight loss), Non-obese negative control group (C-ve) and Obese control positive group (C+ve). Blood glucose and body weight levels were measured at the beginning and end of the experimental in addition to rats’ lipid profiles (total cholesterol; triglycerides;, high dense lipoprotein cholesterol; low dense lipoprotein cholesterol; and very low dense lipoprotein cholesterol). Results presented that obese models received (Cumin)  Cu/( Curcumin ) Cur mixture have the biggest effective significant treatment (about -80% body weight reduction  ) followed by both groups fed mixtures of (Curcumin ) Cur/( Black Papers ) Bp  and (Curcumin) Cur/( Black Papers ) Bp/( Cumin ) Cu; decreased by -68.0 and -65.6g respectively. The study could be more valuable causing significant body weight reduction between obese models, however human studies are needed

Thymoquinone attenuates diethylnitrosamine induction of hepatic carcinogenesis through antioxidant signaling

Hepatocellular carcinoma accounts for about 80–90% of all liver cancer and is the fourth most common cause of cancer mortality. Although there are many strategies for the treatment of liver cancer, chemoprevention seems to be the best strategy for lowering the incidence of this disease. Therefore, this study has been initiated to investigate whether thymoquinone (TQ), Nigella sativa derived-compound with strong antioxidant properties, supplementation could prevent initiation of hepatocarcinogenesis-induced by diethylnitrosamine (DENA), a potent initiator and hepatocarcinogen, in rats. Male Wistar albino rats were divided into four groups. Rats of Group 1 received a single intraperitoneal (I.P.) injection of normal saline. Animals in Group 2 were given TQ (4 mg/kg/day) in drinking water for 7 consecutive days. Rats of Group 3 were injected with a single dose of DENA (200 mg/kg, I.P.). Animals in Group 4 were received TQ and DENA. DENA significantly increased alanine transaminase (ALT), alkaline phosphatase (ALP), total bilirubin, thiobarbituric acid reactive substances (TBARS) and total nitrate/nitrite (NOx) and decreased reduced glutathione (GSH), glutathione peroxidase (GSHPx), glutathione-s-transferase (GST) and catalase (CAT) activity in liver tissues. Moreover, DENA decreased gene expression of GSHPx, GST and CAT and caused severe histopathological lesions in liver tissue. Interestingly, TQ supplementation completely reversed the biochemical and histopathological changes induced by DENA to the control values. In conclusion, data from this study suggest that: (1) decreased mRNA expression of GSHPx, CAT and GST during DENA-induced initiation of hepatic carcinogenesis, (2) TQ supplementation prevents the development of DENA-induced initiation of liver cancer by decreasing oxidative stress and preserving both the activity and mRNA expression of antioxidant enzymes
