The present paper deals with developing of a crimping machine that can crimp hydraulic hoses with its fitting without the use of electricity. Detailed literature review indicates the fabrication of crimping machine that operates with electricity that inspired the authors to develop a hydraulic crimping machine that works without electrical power. Such a crimping machine is very useful when the rig is in movement and suitable for emergency crimping work in order to avoid shutdown time.The author has used Autodesk inventor software for designing critical components of the machine and obtained safety factor more than one for all the critical components. Safety factor less than one leads to the unsafe working condition of the critical parts. Fabrication of the whole assembly has been completed successfully for the required crimping for a hose size of 19.05 mm. The crimping machine has been tested successfully for crimping the required hose size. The design of the machine can be altered so that it can accommodate different die sizes in order to crimp hoses of different sizes.

BACKGROUND Evaluating Health Information System (HIS) quality is strategically advantageous for improving patient care quality. Nevertheless, there is little research evidence identifying and describing what standards, processes, and tools are used to evaluate HIS quality. OBJECTIVE This study aims to illustrate, detail, and discuss the current scenario regarding the standards, norms, processes, and tools used to evaluate HIS quality. METHODS We conduct a systematic literature review (SLR) using review guidelines focused on software and systems. We examined seven electronic databases (Scopus, ACM, ScienceDirect, Google Scholar, IEEE Xplorer, the Web of Science and PubMed) to search and select primary studies. Three researchers and three collaborators participated in the review and quality assessment process of the studies. RESULTS We identified 17 primary studies that have been published in journals and conferences. We found that most of the primary studies address quality evaluation from a management perspective. Second, there is little explicit and pragmatic evidence on the processes and tools that allow evaluation of HIS quality. CONCLUSIONS To promote quality evaluation of HISs, it is necessary to define mechanisms and methods that operationalize the standards and norms of HISs. Additionally, it is necessary to create metrics that measure the quality of the most critical components and processes of HISs. CLINICALTRIAL Does not apply to our study

Purpose of this study was to analyze the effect of the number of electronic furniture, the number of lamps, the number of family dependents, income and electrical power on the electricity demand by households in Amban Village, Manokwari Regency. The data obtained comes from the results of interviews and literature review that supports this research. The analytical tool used in this research is multiple linear regression. The results showed that the number of electrical furniture, the number of lamps and the number of dependents did not affect household electricity consumption, while income and electrical power did not affect household electricity consumption demand.

AbstractObjective: to analyze and summarize knowledge concerning critical components of interventions that have been proposed and implemented by nurses with the aim of optimizing self-care by heart failure patients.Methods: PubMed and CINAHL were the electronic databases used to search full peer-reviewed papers, presenting descriptions of nursing interventions directed to patients or to patients and their families and designed to optimize self-care. Forty-two studies were included in the final sample (n=4,799 patients).Results: this review pointed to a variety and complexity of nursing interventions. As self-care encompasses several behaviors, interventions targeted an average of 3.6 behaviors. Educational/counselling activities were combined or not with cognitive behavioral strategies, but only about half of the studies used a theoretical background to guide interventions. Clinical assessment and management were frequently associated with self-care interventions, which varied in number of sessions (1 to 30); length of follow-up (2 weeks to 12 months) and endpoints.Conclusions: these findings may be useful to inform nurses about further research in self-care interventions in order to propose the comparison of different modalities of intervention, the use of theoretical background and the establishment of endpoints to evaluate their effectiveness.

Purpose The purpose of this paper is to explore the popularity of Japanese lesson study (JLS) beyond Japan and the challenges this translation might pose. It notes that there is not a universally accepted definition of lesson study (LS) and seeks to identify the “critical components” of JLS through a review of the literature. It then uses a systematic literature review of recent studies of the implementation of LS with in-service teachers beyond Japan to analyse the models of LS used against these seven critical components in order to explore the degree of fidelity to the Japanese model. Design/methodology/approach A broad review of the literature on JLS available in the English language identifies seven “critical components”. A systematic literature review of 200 recent English language studies of the implementation of LS with in-service teachers beyond Japan is then carried out. Articles published between 2005 and 2015 are explored, including peer reviewed articles, scientific journals, book chapters and PhD dissertations. This systematic review enables an analysis of the models of LS used in studies from beyond Japan against the “seven critical components” of JLS. Findings The analysis shows that there is not an internationally shared understanding of Japanese lesson study (JLS) and that many of the missing components are those which distinguish LS as a research process, not simply a collaborative professional development approach. It also reveals that UK LS models seem particularly far from the Japanese model in those critical components which connect teachers’ knowledge and understanding within groups, to knowledge and understanding that exists beyond it. The study discusses whether these differences could be attributed to structural or cultural differences between Japan and other nations. Research limitations/implications The search for descriptions of the JLS is limited to articles available in the English language, which, therefore, represent a quite limited body of authority on the “critical components” of LS. The systematic review is similarly limited to English language articles, and there is a clear bias towards the USA, with the Far East and the UK making up the majority of the remaining studies. The study suggests that future research on LS beyond Japan should consider teachers’ attitudes towards the research elements of the process as well as their skills and confidence in carrying out research into practice. Practical implications The study strikes a note of caution for schools wishing to implement JLS as an approach to teacher professional development in the UK and beyond. Japan’s systemic approach has embedded LS experience and expertise into the education system, meaning a uniform approach to LS is much more likely. In addition, other systemic challenges may arise, for example, UK professional development time and resources is not designed with JLS in mind and may therefore require a significant reworking. Originality/value Whilst several systematic reviews of LS have explored its growth, geographical spread, impact and key features, this study provides a different perspective. It analyses whether and to what degree the “lesson study” models these studies describe align with the literature on JLS, and the implications of this for researchers and practitioners.

Vehicle Purchase has been rapidly increasing and since last decade the automobile sector has been growing in double digits in India. There are several factors considered by an individual during the purchase of automobile. With the changing trend and with the pandemic situation safety has also been a key factor that adds into it. This paper tries to examine the factors impacting the purchase behaviour. Initially the literature review aims at finding out the significant variables that act as components in purchase of a vehicle. Subsequently, the paper uses statistical technique of Exploratory factor analysis ( EFA ) to club the different variables into single factor. It was found that 21 variables fall into 6 factors namely Brand trust, Socio-demographic factor, Economic factor, Product and tech factor, Psychographic & safety factor and Govt infra & policies factor

Digital Speckle Photogrammetry (DSP) is proving to be a very useful technique for studying, in the laboratory, the distribution of strain about cracks and other defects in stressed specimens. This non-contact technique is able to resolve strain gradients over a small physical area, for example across a weld heat affected zone. The technique has good potential for use as a condition monitoring tool for a variety of components in electrical power stations. In addition this measurement technique could also be applied to monitor the integrity of critical components of newer generation plant, such as wind turbine generator blades. There are, however, many installation problems to be overcome. For example, there is the need to have regard for the hostile environment in steam generating plant and the demanding conditions to which wind turbine blades are subjected. Ideally the outputs from individual DSP sensors would be used for continuous remote monitoring. However, DSP measurements can also be useful each time the plant is shut down during a plant outage; which would be used to complement data from existing proven rugged monitoring methods. This paper describes ongoing work to develop a ruggedised digital speckle ‘sensor’ and associated image capture system.

Recent attacks against critical infrastructures have shown that it is possible to take down an entire infrastructure by targeting only a few of its components. To prevent or minimize the effects of this kind of attacks, it is necessary to identify these critical components whose disruption, damage or destruction can lead to the paralysis of an infrastructure. This paper shows that the identification of critical components can be made thanks to a particular pattern of the graph theory: the vertex cover. To illustrate how the vertex cover can be useful for the identification of critical components, the electrical power transmission and distribution system of the United States is used as an example. It is shown how it is possible to build an attack scenario against an infrastructure with the results of a vertex cover algorithm.
