Some observations and results concerning submeasures on Boolean algebras

We investigate submeasures on Boolean algebras in the context of Maharam's problem and its solution. We generalise results that were originally proved for measures, to cases where additivity is not present. We investigate Talagrand's construction of a pathological exhaustive submeasure, attempting to give a more explicit description of this submeasure and we also consider some of its forcing properties. We consider the forcing consisting of submeasures that have as their domain a �nite subalgebra of the countable atomless Boolean algebra. We �nd and investigate a linear association between the real vector space of all real-valued functionals on the countable atomless Boolean algebra, which includes the collection of all submeasures, and the space of all signed �nitely additive measures on this Boolean algebra

Sequential closure in the space of measures

We show that there is a compact topological space carrying a measure which is not a weak* limit of finitely supported measures but is in the sequential closure of the set of such measures. We construct compact spaces with measures of arbitrarily high levels of complexity in this sequential hierarchy. It follows that there is a compact space in which the sequential closure cannot be obtained in countably many steps. However, we show that this is not the case for our spaces where the sequential closure is always obtained in countably many steps.Comment: (18 pages, a gap in an argument from the previous version fixed

An example of abet accreditation practice of mechanical engineering program at UAE university

This paper focuses on the Mechanical Engineering Program (MEP) at United Arab Emirates University (UAEU) as a case study in terms of consistent accreditation by the internationally recognized Accreditation Board for Engineering and Technology, Inc. (ABET), where significant proportions of the study give attention towards the recent records of accreditation; granted in 2016. The paper describes the program educational objectives (PEOs), the student learning outcomes (SOs), and the curriculum, direct and indirect assessment tools of the SOs and it’s mapping to the PEO, and the level of attainment achieved is addressed through a case study example

Laboratory Evaluation of Malaysian Cellulose Oil Palm Fiber for Use in Stone Mastic Asphalt Mixes

The primary agricultural product of Malaysia is palm oil. As a result, some two million tons of empty fruit bunch wastes are being dumped behind palm oil mills every year. This is causing serious environmental problems. This paper discusses a study undertaken in 1996 to look into the suitability of the Malaysian oil palm fiber in Stone Mastic Asphalt (SMA) mixes. The oil palm fiber was analyzed and compared with other traditional European fiber that is commonly used in gap-graded mixes. Several experiments were carried out on the fiber including the Fiber Drain Down Test (FDDT) and Morphological analysis using Scanning Electron Microscope (SEM). Besides this, chemical analysis was also carried out with a variation of cellulose content and particle size. The results of the laboratory analysis showed that the Malaysian Cellulose Oil Palm Fiber (COPF) has great potential to be used in SMA mixes

Effects of Poly-MVA on the rheological properties of blood after in-vivo exposure to gamma radiation

AbstractThis study aims to examine the radio-prophylactic effects of poly-MVA against exposure to acute dose of gamma radiation. Adult male rats, weighing 200 gm, were exposed to 6 Gy gamma radiation from Cs-137 source. The animals received daily oral administration of 2 ml/kg body weight of poly-MVA for different time intervals. The prophylactic effect was examined by two modes of administration: two weeks before irradiation and another group which received continuous administration for two weeks before and two other weeks after irradiation (total time of administration 28 days). Different parameters were performed, which include determination of cellular antioxidant enzymes (Glutathione (GSH), catalase and superoxide dismutase) in hepatic cells, the rheological properties of blood, osmotic fragility and scanning electron microscope photography of red blood cells. Exposure to radiation resulted in a significant decrease in cellular antioxidant enzymes (GSH, Catalase and SOD) and decrease in Bingham viscosity, yield stress and aggregation index of blood. Furthermore it induced slightly increase in average osmotic fragility of red blood cells accompanied by decrease in osmotic dispersion and remarkable modification of red blood cell morphology. Administration of Poly-MVA showed markedly elevation in GSH, Catalase and SOD content in liver cells in all treated groups. It also showed improvement in all observed parameters. The obtained results showed that oral uptake of poly MVA posses a radio-prophylactic effect that might be used in planned radiation exposure in diagnosis and radiotherapy

Radio-mitigation effect of poly-MVA after exposure to an acute dose of gamma radiation

AbstractAdult male rats were exposed to a 6Gy single dose from a Cs-137 source. The radio-mitigation effect of poly-MVA was evaluated by daily administration of 2ml/kg of body weight immediately after irradiation for two weeks. The morphological changes in the red blood cells were studied. The osmotic fragility and rheological properties of blood, the alteration in the contents of antioxidant enzymes (glutathione, catalase and superoxide dismutase) and lipid peroxidation in hepatic cells were determined. The results showed that exposure to radiation resulted in significant changes in cellular antioxidant enzymes (GSH, catalase and SOD) and a decrease in the blood Bingham viscosity, yield stress and aggregation index. Furthermore, it induced a slight increase in the average osmotic fragility of red blood cells accompanied by a decrease in osmotic dispersion, as well as a modification of red blood cell morphology. It also caused a significant increase (75%) in the lipid peroxidation 1 day after exposure to radiation, which persisted until the 14th day recorded after irradiation. Oral administration of poly-MVA after irradiation reduced the radiation-induced damage, as seen in the non-significant change in lipid peroxidation compared to the control. It also resulted in improvement in the observed parameters

Drug Abuse-Induced Cardiac Arrhythmias: Mechanisms and Management

Toxicomania is a worldwide emerging problem threatening young population. Several reports highlighted its hazardous cardiovascular effects. Sudden cardiac death secondary to cardiac arrhythmias is the most occupying issue. Different forms of cardiac rhythm disorders may be induced by illicit drug abuse according to the type of drug and the mechanism involved. In this review, we exposed the main ventricular and supraventricular arrhythmia complicating the common recreational drugs, and we explained their different mechanisms as well as the particularities of management

BIM Role within the Conceptual Design Phase: A Case Study of a UK Construction Project

The application of building information modelling (BIM) during the construction cycle of any development varies. Systematically, the way BIM’s applied during the initial phase will have a direct influence on phases that follow afterwards. Previous research focused on the application of BIM and concentrated on various aspects, which included sustainability or how to overcome the loss of data/information. However, it limited its focus on the application during a specific phase of the project. Analysis outlined both the benefits and barriers of applying BIM during the conceptual design phase. The study suggests that an informed evaluation of the application of BIM during any particular phase should take in consideration different stakeholders’ roles and responsibilities
