Background: Maintenance is the core function of biomedical engineering and is essential for the optimum functioning of equipment. This study was undertaken to understand the current maintenance practices of ventilator and its cost implications from administrative point of view. Methodology: 179 Ventilators supplied and installed by one vendor in different wards of the hospital were studied. It was a retrospective, descriptive study. Equipment related data was taken from various service reports. This data was used to calculate spares failure and their costs implication. Results: A total of 692 maintenance visits were undertaken for 179 ventilators of 5 different modals over 27 months by 6 Bio- Medical Engineers (BME). The mean number of spare changed throughout the study was 2.73. The uptime was within satisfactory limits. The yearly repair to cost ratio was 3.50 %. The cost of spare changed was a factor of modal under consideration and the status of equipment concerning its coverage under maintenance contact. Conclusion: The findings of the study should enable researchers in the future to formulate an effective equipment maintenance policy for the hospital.

This study aimed to investigate the cost-benefit of sesame production per hectare under (farmers practice, partial package and full package) practice were farmers performed side by side in their plot. Benefit cost ratio analyses of sesame was conducted in western low lands of Tigray. It includes the production year of 2016/17 E.C and bounded of two woredas with six production sites. In the present study 40 respondents of sesame producers were incorporated. Producers were categorized in to full package (row planting, fertilizer and improved seed users), partial package (broadcast, fertilizer and improved seed users) and non package (broad cast and improved seed). Data was analyzed using SPSS version 16 in terms of percentage, mean, model and others. On the other hand, per hectare yield, return, production cost, and benefit cost ratio of each package were statistically different. The mean productivity per hectare for full package, partial package and non package was 6.55, 5.26 and 3.85 quintal sequentially. The mean return per hectare of full package, partial package, and non package was 26243.75, 21746.25 and 13178.91 birr sequentially. The production cost per hectare of full package, partial package, and non package was 13826.74, 12561.35 and 8681.46 birr respectively. The mean benefit cost ratio was 1.90, 1.74 and 1.50 birr respectively for full package, partial package and non package.

A captive Indo-Pacific bottlenose dolphin named “Jedol” was released from a zoo into the wild, in Jeju Island Sea off South Korea, in July 2013 to improve his welfare. Since he was illegally captured off the coast of Juju Island in May 2009, he had been performing in dolphin shows at Seoul Zoo, which is owned and operated by the Seoul Metropolitan Government. The release demanded considerable public expenditure, of which the source was local taxes gathered from the residents of Seoul. This paper seeks to conduct an ex-post evaluation of the release, employing the contingent valuation (CV) technique. A total of 500 households living in Seoul in 2013 participated in the CV survey to report their willingness to pay (WTP) for the release. Fifty-two percent were willing to accept an increase in local taxes over the next five years to carry out the release. The mean household WTP estimate was obtained as KRW 4880 (USD 4.56) per annum. The present values of the total WTP and the cost of the release are KRW 79.82 billion (USD 74.53 million) and KRW 751 million (USD 701,000), respectively, in 2013. Interestingly, the former is much more than the latter. We can conclude that the release was desirable from the point of view of Seoul residents.

AbstractThe fiddler crabs Uca mordax and U. burgersi, living sympatrically from Guatemala to southern Brazil, were until recently discussed as belonging to only one species, because their similarities refer not only to morphology but also to their waving displays, which were called "indistinguishable". A frame-by-frame analysis of motion pictures taken in Trinidad (W.I.) confirmed the presence of many similarities in respect to the special "jerking" type of waving display, the mean duration of routine waves, the effect of increasing excitation, the pattern of leg-waving and the presence of a "precursory" downstroke" of the major cheliped. However, a closer analysis of certain components or elements of the display yielded various interspecific differences. In burgersi there is the tendency to omit the precursory downstroke and to extend all motion components at the cost of all kinds of pauses, while in mordax the contrary is true. Furthermore, the movements of the minor cheliped show a different pattern in the two species. The differences found are discussed in respect to differences in the allometry of the major cheliped and from an evolutionary point of view. It is concluded that the waving display of mordax represents the more ancestral type. The role of the waving display as a possible means of reproductive isolation will be discussed in part II of this study dealing with the acoustic display.

AbstractThe main objective of the paper is to evaluate the potential of reducing the environmental impact of civil subsonic aviation by using hydrogen fuel. The paper is divided into three parts of which this is Part III. In Part I the background, prospects and challenges of introducing an alternative fuel in aviation were outlined. The aero engine design when using hydrogen was covered in Part II. In this paper, Part III, the subjects of optimum cruising altitude and airport implications of introducing liquid hydrogen-fuelled aircraft are raised.For minimum global warming, the results of a preliminary analysis associated with large uncertainties suggest that cryoplanes should cruise at an altitude of about 2-3km below where conventional aircraft cruise today. Ignoring the cost implications, from an airport infrastructure point of view, it seems feasible to change to hydrogen use. With respect to the availability of energy, it would be reasonable to change from kerosene to liquid hydrogen as fuel for all civil aviation refuelling in Sweden.

Natural Science Collections (NSCs) contain specimen-related data from which we extract valuable information for science and policy. Openness of those collections facilitates development of science. Moreover, virtual accessibility to physical containers by means of their digitization will allow an exponential increase in the level of available information. Digitization of collections will allow us to set a comprehensive registry of reliable, accurate, updated, comparable and interconnected information. Equally, the scope of interested potential users will largely expand and so will the different levels of granularity required by researchers, institutions and governmental bodies. Meeting diverse needs entails a special effort in data management and data analysis to extract, digest and present information on a compressed but still precise and objective-oriented format. The Collections Digitisation Dashboard (CDD) underpins such an attempt. The CDD stands as a practical tool that specifically aims to support high-level decisions with a wide coverage of data, by providing a visual, simplified and structured arrangement that will allow discovery of key indicators concerning digitization of bio- and geodiversity collections. The realm of possible approaches to the CDD covers levels of digitization, collection exceptionality, resourceavailability and many others. Still all those different angles need to be aligned and processed at once to provide an overall overview of the status of NSCs in the digitization process and analyse its further development. The CDD is a powerful mechanism to identify priorities, specialisation lines together with regional development, gaps and niches and future capabilities as well, and strengths and weaknesses across collections, institutions, countries and regions. It can perfectly underpin measurable and comparable assessments, with evolution indexes and progress indicators, all under an overarching homogenous approach. The Distributed System of Scientific Collections (DiSSCo) Research Infrastructure, currently in its preparatory phase, is built on top of the largest ever community of collections-related institutions across Europe and anchored on the Consortium of European Taxonomic Facilities (CETAF). It aims to provide a unique virtual access point to NSCs by facilitating a large and massive digitisation effort throughout Europe. Setting up priorities and specialization areas is pivotal to its success. To that end, the DiSSCo CDD will provide a valuation tool to summarize and showcase NSC's digitization status on a first-hand visualization. Different projects and initiatives will contribute, jointly and on a synergetic basis, to the production of the DiSSCo CDD. The ICEDIG project will address its basics features, terms of classification and tiers of information, and will produce a prototype and a set of recommendations on how to better attempt a massive dashboard by collating specific collections-based information and defining global strategic representations. CETAF working groups on collections and digitization will provide the desired homogeneity in describing and capturing the different implementation requirements from the users’ perspectives, which will be complemented by the contributions made under the umbrella of the COST Action MOBILISE. The Action will use networking activities to identify the right standards and policies to enable enlarging the scope of the DiSSCo CDD and its broader implementation by linking to the TDWG criteria and adopted standards. Complementarily, the ELViS platform to be developed under the SYNTHESYS+ project will provide the right virtual environment. Furthermore, SYNTHESYS+ will address the assessment capabilities of the CDD to enable the visual representation becoming a practical assessment mechanism and endow it with a dynamic feature for analysis over the time. The DiSSCo CDD will thus become an instrumental mechanism for decision-taking that will be embedded into the clustering initiative of products and services provided to the EOSCby the ENVRI-FAIR project in the environmental domain.

A research was conducted at Pyuthan district in order to access the profitability of rice production in Pyuthan during the summer season of 2018-2019. Altogether of 70 respondents were selected randomly and surveyed with semi-structured interview schedule. The results revealed that the average land holding was 0.45 hectare, and the average rice cultivation area was 0.34 hectare. On the basis of average rice cultivation area, farmers were categorized as small (39) and large (31). The cost and return was calculated among both the category. t- test was used to compare the mean costs of inputs between small and large farmers. Cost for agronomic operations was found far higher (more than 70%) in both the category in compared to the cost of inputs. Contribution of rice grains and straw to overall return was 72.65% and 27.35% respectively. Benefit Cost ratio was found greater among large farmers. The average B:C ratio was 1.51, which was fairly higher than 1.14 in Dang district indicating the investment of rice production is expected to deliver a positive net return to the farmers of the study area. In a nutshell, rice cultivation is an important enterprise that should be encouraged, considering the fact that it is a major staple crop.


The article focuses on the problem of the lack of objective evaluation of space-planning arrangement of buildings as a creative approach of the architect to the performing of functional tasks by the object. It is proposed to create a methodology for assessing the functional of space-planning solutions of buildings on the basis of numerical simulation of functional processes using the theory of human flows. There is a description of the prospects of using this method, which makes it possible to increase the coefficient of compactness, materials and works saving, more efficient use of space, reduce the cost of the life cycle of the building, save human forces and time to implement the functional of the building. The necessary initial data for modeling on the example of shopping and shopping-entertainment centers are considered. There are three main tasks for algorithmization of the functional of shopping centers. The conclusion is made about necessity of development of a method for objective assessment of buildings from the point of view of ergonomics of space-planning decisions based on the study of human behavior in buildings of different purposes.

The article deals with modern mechanisms for managing social protection of the population by the state and the private sector. From the point of view of forms of state regulation of the sphere of social protection, system indicators usually include the state and dynamics of growth in the standard of living of the population, material goods, services and social guarantees for the poorly provided segments of the population. The main indicator among the above is the state of the consumer market, as one of the main factors in the development of the state. Priority areas of public administration with the use of various forms of social security have been identified. It should be emphasized that, despite the legislative conflicts that exist today in Ukraine, mandatory indexation of the cost of living is established, which is associated with inflation. Various scientists note that although the definition of the cost of living index has a well-established methodology, there are quite a lot of regional features in the structure of consumption. All this is due to restrictions that are included in the consumer basket of goods and different levels of socio-economic development of regions. The analysis of the establishment and periodic review of the minimum consumer budgets of the subsistence minimum and wages of the working population and the need to form state insurance funds for unforeseen circumstances is carried out. Considering in this context the levers of state management of social guarantees of the population, we drew attention to the crisis periods that are associated with the market transformation of the regional economy. In these conditions, there is a need to develop and implement new mechanisms and clusters in the system of socio-economic relations. The components of the mechanisms ofstate regulation ofsocial guarantees of the population are proposed. The deepening of market relations in the process of reforming the system of social protection of the population should be aimed at social well-being.
