It is first argued that the prohibition of Termination of life on request confers an inalienable right to life. A fight is inalienable if it cannot legitimately be waived or transferred. Since voluntary euthanasia entails waiver of the right to life, the inalienability yields that it cannot be justified. Therefore, any ethical position that is in favor of voluntary euthanasia has to argue that the right to life is an inalienable right and accept the conclusion that killing on request is justified.展开更多

Methods:The single aerobic strains were isolated from these products respectively and disc agar diffusion assay was proceeded to determine the susceptibility. Results: Probiotics tested in the study mostly showed multiresistant to the agents. Lactobacillus acidophilus LAP, LAB, Lactobacillus bulgaricus LBJ and Streptococcus therrnophilus STJ were resistant to vancomycin. Conclusion: Drug resistance exists in most of commercial probiotics. The evaluation and monitoring of safety of probiotic products for medical purpose should be paid great attention.展开更多

Therefore, an innovative technique for early detection of potential failure and condition monitoring is urgently required by many engineers. This document describes a novel approach to improve industrial equipment safety, reliability and life cycle management. A new field portable instrument called the "IMS (indicator of mechanical stresses)" utilizes magneto-anisotropic ("cross") transducers to measure anisotropy of magnetic properties in ferromagnetic material. Mechanical stresses including residual stresses in Ferro-magnetic parts, are "not visible" to most traditional NDT (non-destructive testing) methods; for example, radiography and ultrasonic inspection. Stress build-up can be the first indicator that something is faulty with a structure. This can be the result of a manufacturing defect; or as assets age and fatigue, stress loads can become unevenly distributed throughout the metal. We outline the evaluation of IMS as a fast screening tool to provide structural condition or deterioration feedback in novel applications for pipelines, petrochemical refinery, cranes, and municipal infrastructure.展开更多

Knowledge and assessment of impacts of aging on structures are essential to plant life extension analysis,especially performance to severe loadings such as loss-of-coolant-accidents or major seismic events. Plant life extension issues are of keen interest in countries (like the United States) which have a large,aging fleet of NPPs. This paper addresses the overlap and relationship of structure aging to severe loading performance,with particular emphasis on containment structures.展开更多

This project was more prefered compared to building another power plant in Bali which could raise social and cultural resistance. Life cycle cost method was used to complete the financial feasibility study to ensure if the project has economic benefit, and the asset would be used effectively and efficiently along its benefit period. In this paper, a life cycle cost will be simulated to analyze which alternative is the most profitable: installation circuit III and IV in 2012 or installation circuit III in 2012 and circuit IV in 2017 in accordance with load forecasting demand. This study is used to help the management to make a decision about the project.展开更多

In special cases, structures are designed in view of longer life cycle, such as bridges, important infrastructure facilities, important religious structures or in case of extended returning period of seismic event or floods. Beside issues of durability and maintenance aspects, this involves also the need to cover the probability of exceeding characteristic design live loads during the extended period, while keeping the same levels of the accepted risk that were assumed by the various codes, as good enough for the standard 50 year life cycle. Bearing in mind that design procedures, formulations, materials characteristic strengths and partial safety factors are used for these structures as per the existing codes, scaling of partial safety factors, or alternatively an additional "compensating" factor is required. A simplified approach and procedure to arrive at a reasonable calibration of the code safety factors based on 50 years to compensate for an extended life cycle, based upon structural reliability considerations, is proposed.展开更多

Based on the characteristic of limited energy for WSNs in confined underground area such as coal face and laneway, we presents an energy- efficient clustering routing protocol based on weight (ECRPW) to prolong the lifetime of networks. ECRPW takes into consideration the nodes' residual energy during the election process of cluster heads. The constraint of distance threshold is used to optimize cluster scheme. Furthermore, the protocol also sets up a routing tree based on cluster heads' weight. The results show that ECRPW had better perfor- mance in energy consumption, death ratio of node and network lifetime.展开更多

The primary target is to meet the requirements provided by the local regulations from the regulatory offices. The controlling, monitoring and power supply of safety functions have to comply with these regulations. Any deviations from the existing safety analysis report (SAR) have to be corrected. On top of the safety measures the general technical status should be raised to extend the lifetime to 60 years. A high availability during the modernization has to be assured.展开更多

Using recorded figures for the installation costs and performance, a financial life cycle analysis has been undertaken to determine the cost effectiveness of the system. The time value of money is considered and an LCC (life cycle cost) analysis undertaken to identify the cost-effectiveness of the solution. It shows that while a direct heating and hot water system incorporating STES can be economically viable in a Swedish maritime climate in the long term, assistance such as that provided by government incentives is required to assist with the high capital cost of the initial investment.展开更多

A relatively large sin θ13= 0.13 is naturally obtained. The model further predicts vanishingly small CP violation in neutrino oscillations. While the high scale supersymmetry generically results in a Higgs mass of about 141 GeV, our model reduces this mass to 126 CeV via introducing SU(2)L triplet fields which make the electroweak vacuum metastable (with a safe lifetime) and also contribute to neutrino masses.展开更多
