Development of the automotive industry, including so-called dowsizing and rightsizing, entails the need to ensure, and hence to verify, the stringent cleanliness levels of an increasing number of car components. The assurance of proper cleanliness level requires knowledge of the entire production process and precise information on the contaminants that will allow to identify their sources. Obtaining reliable cleanliness information requires establishing of many different factors, i. a. selection of proper contamination extraction and collection technique, proper parameters of extraction, validation of extraction procedure, methods of particles analysis. Analytical techniques which are implemented include gravimetric, optical microscopy and advanced techniques like scanning electron microscopy. This work present’s actual state of knowledge regarding technical cleanliness analysis of components. Important aspects of QA&QC in technical cleanliness assessment are also discussed.

During production of mechanical components, residual dirt collects on the surfaces, thus creating a contamination that affects the durability of the assembled products. Residual particles are currently analyzed based on microscopic 2d images. However, the particle's shape is decisive for the damage it can cause, yet can not be judged reliably from 2d data. Micro-computed tomography allows to capture the complex spatial structures of thousands of particles simultaneously. Now new methods to characterize three dimensional shapes are needed to establish 3d cleanliness analysis. In this work, unambiguously indicative geometric features are defined and it is investigated how they can yield a reliable classification in three typical classes: fibers, chips and granules. Finally, the efficiency of the proposed method is proved by analyzing samples of real dirt particles.

After technical results presented the last two years and new results on volatile contamination, this paper reviews the contamination management in advanced microelectronic and proposes rules for advanced Integrated Circuits (IC) manufacturing. The competitiveness of a production line is insured only if right contamination management rules are applied. These rules must allow a fast introduction of disruptive technologies while keeping as low as possible associated costs: processing on shared equipments, determination of acceptable levels of contamination with a good understanding of their detrimental impact on devices, knowledge on contamination dissemination mechanisms. Moreover, a control of contamination using appropriate cleanings and metrologies is mandatory.

To correctly assess the cleanliness of technical surfaces in a production process, corresponding online monitoring systems must provide sufficient data. A promising method for fast, large-area, and non-contact monitoring is hyperspectral imaging (HSI), which was used in this paper for the detection and quantification of organic surface contaminations. Depending on the cleaning parameter constellation, different levels of organic residues remained on the surface. Afterwards, the cleanliness was determined by the carbon content in the atom percent on the sample surfaces, characterized by XPS and AES. The HSI data and the XPS measurements were correlated, using machine learning methods, to generate a predictive model for the carbon content of the surface. The regression algorithms elastic net, random forest regression, and support vector machine regression were used. Overall, the developed method was able to quantify organic contaminations on technical surfaces. The best regression model found was a random forest model, which achieved an R2 of 0.7 and an RMSE of 7.65 At.-% C. Due to the easy-to-use measurement and the fast evaluation by machine learning, the method seems suitable for an online monitoring system. However, the results also show that further experiments are necessary to improve the quality of the prediction models.

The large high-power solid lasers, such as the National Ignition Facility (NIF) of America and the Shenguang-III (SG-III) laser facility of China, can output over 2.1 MJ laser pulse for the inertial confinement fusion (ICF) experiments. Because of the enhancement of operating flux and the expansion of laser driver scale, the problem of contamination seriously influences their construction period and operation life. During irradiation by intense laser beams, the contaminants on the metallic surface of beam tubes can be transmitted to the optical surfaces and lead to damage of optical components. For the high-power solid-state laser facilities, contamination control focuses on the slab amplifiers, spatial filters, and final-optical assemblies. In this paper, an effective solution to control contaminations including the whole process of the laser driver is put forward to provide the safe operation of laser facilities, and the detailed technical methods of contamination control such as washing, cleanliness metrology, and cleanliness protecting are also introduced to reduce the probability of laser-induced damage of optics. The experimental results show that the cleanliness level of SG-III laser facility is much better to ensure that the laser facility can safely operate at high energy flux.

While it is generally acknowledged in our industry that people are the most important asset, the importance of technical training for furnace operators is often overlooked. The primary focus for training is often on the down stream process where the final product is either being cast or fabricated. The furnace operators have a key role since they have direct influence on factors that dramatically govern a range of costs factors which include: productivity; melt loss; metal content in the dross; energy usage, and metal cleanliness.

Water-saving urinals, such as waterless and low-flush urinals, have a great potential for water conservation by using 0 ∼ 0.8 l/flush compared with ordinary urinals, which use 2 ∼ 4 l/flush. However in some cases, water-saving urinals are not desirable because of technical problems, such as urine scale formation which makes the urinal dirty and blocks pipes. Also, some cultures do not allow the use of waterless urinals because of their notion of cleanliness. In this paper, factors causing urine scale formation have been identified from laboratory tests on pure urine and several types of flushing water. Some meaningful solutions for managing and solving urine scale problems have been suggested. In particular, the results show that mixing urine with seawater or high salinity groundwater will increase the potential of urine scale formation by increasing total dissolved solids (TDS) and pH. However, using rainwater for urinal flushing can significantly reduce the TDS and pH. These findings could support the use of water-saving toilets in Islamic societies by ensuring that the cleanliness of urinals can still be achieved.

BACKGROUND: In this Paper we will present the evolution of the best practice for biobanks, the technical and medical standards for collecting, processing and storing, as well as the socio-economic standards for biobank management. AIM: The aim of this Thesis is to analyse and to present the methods for projection of spaces for good manufacturing practice. METHODS: The European Union has adopted guidelines for good manufacturing practice which define the requirements for manufacturing of sterile products. In the following text we will describe the details for determining microbiological cleanliness and cleanliness of the particles in the air, on the surfaces, etc. RESULTS: The length of time between the collecting of blood or tissues could affect the final result. The preparation of sterile products requires special conditions, in order the risk of microbiological contamination and certain pyrogenic contaminations to be minimized. We make difference between four levels of guidelines for good manufacturing practice, which in this Paper are taken from the practice of the European Union. Level A is local zone with high-risk procedures, e.g. filling, closing of bottles, opening of ampoules and bottles and making septic connections. Level B is aseptic preparation and filling of the samples. Level C and D are the clean spaces for less critical procedures for preparation of sterile products. CONCLUSION: Technical standards, medical standards, socio-economic standards for biobank management, informatics practices for biobanks, economic recommendations for biobanks have been established, as well as a quality of biobanks has been provided.

learning has been adopted by businesses to analyze their vast data in order to make strategic decision. However, knowledge in machine learning and technical skill are usually required to prepare data and perform machine learning tasks. This obstacle prevents smaller businesses with no technical knowledge to utilize machine learning. In this paper, we propose an architecture for simplified and automated machine learning process currently supporting the data classification task. The architecture includes a method for characterizing datasets, which allows for simplifying and automating machine learning model and hyperparameter selection based on historical execution configurations. Users can simply upload their datasets via a web browser, and the system will determine the possible models and their hyperparameter configurations for the users to choose from. The prototype shows the feasibility of the proposed architecture. Although the accuracy is still limited by the small execution history and the cleanliness of the input datasets, the architecture can minimize user involvement in the machine learning process so that non-technical users can perform data classification through a web browser without installing any software.

This paper discuss an new type servo valve, aiming at two main defects of performance of globe valve which are commonly used in mine safety cabins in China, in order to bring up a better solution to replace old valves. On one hand, most of globe valves are manual ball valves whose oxygen content cannot be accurately controlled and can only be estimated by human respiratory sense, ended in large errors[1]. On the other hand, although in market there is oxygen-concentration test equipment, the separation of valve components and manual control switch, leads to complicated procedures and management inconvenience. For solving these problems, an innovative valve mechanical structure is designed, with its servo system bringing up. The proportional valve measures the room oxygen concentration in real time, closed-loop controlling of electric valve-opening, so that the concentration of oxygen in the ambient air is maintained at a desired level. The principle of this implementation is that an explosion-proof motor drives the roller cam to convert valve core into reciprocating linear motion, separating O-ring and valve body end-face to control valve core achieving the opening and closing functions. Since there is no relative motion between O-ring and valve body, it definitely avoids problems of uncontrollable particles caused by abrasion and ensures a high cleanliness of flow path. In addition, electric servo valve controls the precise oxygen concentration, automatically. Compared with manual air supply valve, this valve has advantages of high cleanliness, reliable sealing, easy assembly, maintenance, and automation. It provides a new technical approach for design of special industrial and mining value.

Abstract Background Microbial contamination of the patient environment has been associated with healthcare-associated infections. Objective assessment of environmental cleanliness is recommended by the CDC to identify improvement opportunities. Methods currently used to assess cleanliness and microbial dynamics differ in their sensitivity, specificity, cost, ease of use, and turnaround time. We compared five assessment methods to examine these characteristics. Methods The bedrail, overbed table, remote control, and toilet seat in occupied patient rooms were sampled and assessed with: adenosine triphosphate (ATP) luminescence technology (LT), Replicate Organism Detection And Counting (RODAC) plates, C diff Banana Broth™ (CDBB), conventional aerobic culture (CC) and antimicrobial susceptibility testing, and shotgun next-generation sequencing (NGS) and analysis using metagenomic software. Results One hundred forty surfaces from 35 rooms were sampled. Of 70 surfaces sampled by both ATP LT and RODAC, 42 (60%) had concordant “pass” or “fail” results. Of 28 discordant samples, 26 (93%) passed by RODAC but failed by ATP LT. CDBB testing identified Clostridioides difficile on two surfaces in one room; C. difficile was also identified by NGS in this room. NGS had 100% concordance with organisms identified by CC, and identified approximately 20 additional organisms not identified by CC per surface. 38% of organisms identified by NGS were potential pathogens, compared with 13% through CC. No correlations were found between the primary quantitative assessments (RODAC bacterial concentrations and ATP LT ATP concentrations) and quantitative components of CC (presence/absence of organisms) and NGS (read numbers). Conclusion ATP LT and RODAC plates both provide useful quantitative cleanliness data, although high ATP values did not always indicate the The presence of viable aerobic bacteria. CDBB may be a useful method for identifying C. difficile in the environment, but larger studies of the performance characteristics of CDBB are needed. CC and NGS provided useful organism identification information, but NGS had higher sensitivity for detecting potentially pathogenic organisms. The clinical implications of NGS results must be further studied and cost and technical expertise are important considerations. Disclosures N. B.

The food allergy and allergen control are important for global health concerns. Latent allergens are a paramount problem in the specialized food products. Cross-contact and post-cleaning contamination are the main sources of these problems. According to the norms of the Technical Regulation Custom Union N 027/2012 and the Codex Stan 118-79 standard, the gluten content in food products should not exceed 20 mg / kg of the product. The purpose of this study was to analyze raw materials for the gluten-free food products manufacture to justify the HACCP system implementation. The samples of gluten-free flours were selected as research objects to assess the cleanliness of storage, transportation and production facilities in factories producing gluten-free products. In this study, we analyzed the samples of gluten-free flours to assess the cleanliness of storage conditions, transportation and industrial premises in gluten-free factories. The results showed that when using raw materials stored under improper conditions an increase in the gluten content in the final product is observed. We concluded that the gluten-free flours storage conditions in a room with gluten-containing raw materials are unacceptable, because the final product will have high gluten content. Thus, this product cannot be marketed as gluten-free. In addition, we analyzed the washes from the equipment after baking cookies from these flours. We found that in order to comply with regulations, it was necessary to conduct 3 consecutive washing

The paper presents a comparison of two fluids quality. The first one was mineral oil type UTTO which is commonly used in the transmission and hydraulic systems of agricultural tractors. The second one tested was biodegradable hydraulic fluid type ERTTO which could replace the toxic mineral oil. Both fluids were tested under the same test conditions using a special test device. The selected parameters of the hydrostatic pump were evaluated. The tests were evaluated according to the parameters describing the technical state of the hydrostatic pump as follows: flow efficiency, decrease of flow efficiency and cleanliness level of the fluid tested. This additional measurement verifies the test results. On the basis of the results achieved, we can state that the biodegradable hydraulic fluid exerts no harmful influence on the technical state of the hydrostatic pump. Therefore, the biodegradable fluid tested can be applied to the agricultural tractor. Has been demonstrated that the selected parameters are suitable for the evaluation of hydraulic fluid during its working performance. Therefore, these parameters will be used in the next examination of the fluid under operational conditions of an agricultural tractor.

The work investigated the possibility of using the technical lingo-sulfonate as a binder for the manufacture of small cores by blow-off methods in the production of shaped cast-iron casting, similar to the dominant at the present time Cold-Box-Amin process. It is shown that the advantage of lignin materials is their safety, manifested both in the workplace - directly in the foundry, and in ensuring environmental cleanliness in the area of the location of such production. It is indicated that, when switching to the proposed lignin materials, the price of binders can be reduced by two orders of magnitude. Experimental compositions of mixtures are proposed, and their tests are carried out. The quantitative characteristics of the composition of the sand-oligo-sulfonate mixture are established. As a result, a pilot batch of rods was produced, and high-quality shaped cast iron castings were made. Special attention is paid to the demand to develop the specialized equipment, focused on lignin binders.

Abstract This study was conducted to identify the gaps that exist between ventilated improved pit (VIP) latrine construction practices in Cape Coast, Ghana, and conventional technical guidelines, and to assess how any non-compliance with technical guidelines influences the users' perception of odour and fly nuisances. An inspection guide was used to assess 127 VIP latrines, while a questionnaire survey was used to obtain feedback from 211 users of the latrines on their perception of odour and fly nuisance. Not a single latrine was found to be fitted with a vent pipe that satisfied the recommended diameter of 150 mm. Aside from the vent pipe diameter, only 5.5% of latrines complied with all four other design guidelines that were assessed. However, with the exception of failure to install insect screens on vent pipes, which was associated with the users seeing flies in the latrine cubicles, failure to comply with other guidelines did not necessarily lead to significantly higher user perception of the targeted nuisance. The findings of the study suggest that user perception of odour in their latrines may be more influenced by non-structural factors such as the management or cleanliness of the latrines rather than their structural designs.

Increased internet usage and fast-paced consumer’s demands have created business opportunities, including online food delivery services. However, competition with similar national-scale businesses allegedly contributed to the decline in the number of XYZ company orders, one of the food-delivery service providers in Yogyakarta. Therefore, this study aimed to identify the need’s attributes of the daring food delivery service consumers, to find out the service-quality satisfaction level, and to determine the technical requirement for improving the delivery service. The combination of Servqual and Quality Function Deployment (QFD) were then used to reach the research goals. The online survey instruments, which were borrowed from the previous studies and adapted for this study, were distributed from June 2016 to February 2017 to more than 700 XYZ’s consumers, with the number of respondents who answered as many as 213 peoples. Cronbach’s Alpha, the most common test for multiple Likert questions in a survey, was then used for analyzing the collected data. The result shows that order conformity; politeness and friendliness of messengers and administrative workers; cleanliness of food box; a good conditionof received ordered food; and affordable delivery costs are the top five attributes of consumer needs. Meanwhile, the top five observed technical requirements are the provision of skills training to messengers and administrative workers; periodic evaluations of service performance; the regular addition of food outlet members; providing map feature on the company website, and provision of ordering applications. The identified requirements can benefit local food delivery service providers in competing with national scale competitors and adapt to disruptive age.

The technical and commercial development of Thixomolding® of magnesium (Mg) alloys is described. Based on the MIT semi-solid casting discovery, Dow Chemical adaption to Mg and Thixomat technical findings, Thixomat commercialized this process world-wide with Japan Steel Works (JSW) and numerous licensees in 13 countries. Some 480 Thixomolding machines have been commissioned by JSW to produce a wide range of parts for application in the communication/electronic, auto, sporting goods and hand-held tool markets. The advantages over conventional casting of Mg have been established in cleanliness, safety, worker comfort, machine portability, longer die life and reduced scrap. The competiveness of Thixomolding Mg has been enhanced by more durable and less expensive machine parts, longer die life, higher raw material yields by using hot nozzles and amenability to using recycled Mg scrap. The portability of this “foundry inside a machine” and availability of pre-owned machines allows quick set-up of Thixomolding operations. Several technical advances in Thixomolding are described. Solids content was optimized. Hot nozzles increased the part yield to >90% of the granule Mg alloy feed. Special steel barrels and liners are available to substitute for expensive Superalloys. In addition to conventional AZ91D and AM60, a wide range of Mg alloys can be Thixomolded. With Dead Sea Magnesium, AM70-TH and AJX810-TH were developed for improved ductility or creep strength. Low porosity and fine grain size of Thixomolding open the door to blister-free thermomechanical processing (TTMP) to boost the tensile and fatigue strength and ductility.

The cleanliness of hydraulic oil can reflect the service life of the oil and the wear state of hydraulic machinery. An impedance sensor is proposed to distinguish multi-contaminants in hydraulic oil. The impedance sensor has two detection modes: the inductance-resistance mode is used to detect metal debris, and the capacitance mode is used to distinguish water droplets and air bubbles. By adding a built-in silicon steel strip and an external silicon steel strip with high magnetic permeability, the distribution area, strength, and uniformity of the magnetic field are enhanced to improve the detection sensitivity under inductance and resistance parameters. In addition, the silicon steel strips are used as electrode plates to introduce capacitance parameter detection. The experimental results show that the resistance detection method based on coil successfully improves the detection ability for non-ferromagnetic metal debris. The impedance sensor for distinguishing multi-contaminants in hydraulic oil can provide technical support for fault diagnosis of offshore hydraulic machinery.

A paucity of information exists to characterize the relationship between the health status of elderly people and their physical environment. The Canadian Study of Health and Aging (CSHA) is a multicenter study of the distribution of dementia among community-dwelling and institutionalized Canadians aged 65 years and older. The study also provides the opportunity to examine issues such as the physical environment which may be related to the health of elderly people. Six items were used to assess the cleanliness, neatness, and maintenance of the inside and outside of the homes of 8,134 community-dwelling individuals. Data were also obtained to evaluate cognition, physical health, and functional capacity. Five years after the original survey, information pertaining to subsequent institutionalization and/or mortality was obtained. A significant relationship was found between classification of physical environment and the outcomes of institutionalization and mortality. The likelihood of both adverse outcomes was notably higher for individuals living in a “less than ideally maintained environment” compared to an “ideally maintained environment.” Limitations of the six items used to assess the physical environment and ways in which to improve the sensitivity of the items, consequently avoiding measurement bias, are discussed.

В статье рассмотрены основные технические средства – береговые радиолокационные станции, которые как объект эксплуатации, представляют собой сложную техническую систему, состоящую из конструктивно оформленных элементов с разным уровнем надежности, и часто имеющих самостоятельное назначение, свои частные цели и задачи функционирования. Этап эксплуатации технических средств играет особую роль в процессе жизненного цикла системы управления движением судов (СУДС), поскольку все усилия, затраченные на создание высококачественной системы, могут быть сведены на "нет" неправильно или нерационально организованной эксплуатацией. Следовательно, эксплуатация должна обеспечивать наибольшую эффективность функционирования технических средств. Поэтому, проблема повышения уровня эксплуатационной надежности технических средств СУДС является актуальной, ибо повышение эффективности эксплуатации портов, флота и обеспечение чистоты среды немыслимо без технического, методического и организационного совершенствования береговых СУДС, оборудованных современными средствами радиолокации, связи, телевидения и программно-аппаратными комплексами. Поэтому, объектом исследования являются береговые радиолокационные станции, предмет – их тактико-технические характеристики. Цель исследования – анализ работы технических средств действующей СУДС порта Новороссийск, осуществляющих сбор и передачу информации о судоходной обстановке в районе действия, для интерференционного анализа конфигурации береговых радиолокационных станций при различных параметрах антенн. The article discusses the main technical means - coastal radar stations, which, as an object of operation, are a complex technical system consisting of structurally designed elements with different levels of reliability, and often having an independent purpose, their particular goals and objectives of functioning. The operational phase of the technical means plays a special role in the life cycle of a vessel’s traffic service (VTS), since all the efforts spent on creating a high-quality system can be canceled out by improper or inefficient operation. Consequently, the operation should ensure the highest efficiency of the functioning of the technical means. Therefore, the problem of increasing the level of operational reliability of the technical means of the VTS is urgent, because increasing the efficiency of the operation of ports, the fleet and ensuring the cleanliness of the environment is unthinkable without the technical, methodological and organizational improvement of the coastal VTS equipped with modern means of radar, communications, television and software and hardware complexes. Therefore, the object of research is coastal radar stations, the subject is their tactical and technical characteristics. The purpose of the study is to analyze the operation of the technical means of the operating VTS of the port of Novorossiysk, collecting and transmitting information about the navigational situation in the area of ​​operation, for interference analysis of the configuration of coastal radar stations with various antenna parameters.

It is well known that the surface state (cleanliness, composition) of galvanized steel prior to the application of an organic coating is an important parameter. The surface state will affect the adhesion properties of the complete system and therefore will also impact its corrosion resistance and its tendency to blistering. Before the application of a pretreatment layer, galvanized steel strips are normally alkaline cleaned. This step is known to remove the native oxide film formed on hot dip galvanized steel after processing and appears as one of the most important steps to study the impact of the surface properties on the performance of painted systems. This study focused on making use of the cleaning step to input a variability on the surface composition (mainly surface concentration of aluminum) and evaluate its consequence(s) on the performance of a complete paint system. The results showed that, a variability in terms of surface aluminum concentration could be achieved by the cleaning step and that signs of performance improvement in terms of adhesion and tendency to blistering were spotted with a low content of aluminum at the surface.

Both clients and providers expressed dissatisfaction for inadequate quality of care represented by poor cleanliness, long waiting time with less consultation time, poor compassion by providers, inadequate supply of drugs and unnoticed cost for services varied by level of facilities. Inadequacy in human resource and absenteeism and poor laboratory service were reported to worsen the condition especially at lower level of service delivery. Thus this study explored some important factors like poor quality of care, inadequate technical competencies, information exchange and follow-up services. A deficit in supplies and logistics are strong barrier in regards to quality of care at various levels which needs to be addressed immediately.Keywords: Bangladesh; Maternal health; Newborn health; Quality of careOnline: 13 August 2009DOI: 10.3329/bmrcb.v35i2.3044Bangladesh Med Res Counc Bull 2009; 35: 53-56

Cool-drawn 1Cr18Ni9 stainless steel wires of 0.1~0.5 mm can be woven and punched to prepare porous metal filters. There is certain amount of connected micron pores in the transformable components. Filtration mechanism of this porous material is investigated and three series of samples with different diameter of wires, porosities and filtrating ranges are prepared. Filtration performances compares experiments are carried out on a kind of chocolate milk with the brand of Sanyuan. Three-dimensional microscopy, KEYENCE VHX-600, is applied to investigate the diaphragms before and after filtrating. Portable contamination analysis kit, HPCA-2, is chosen to identify the degree of contaminating. Results indicate that these kind of porous metal filters have valid solid/fluid separating effects. Wires diameters and other preparation parameters will identify the porosity. Thinner wires contribute to more and tinier porous and will block particles effectively. Thickness of filters plays the similar role of filtration layer. Higher porosity will increase the cleanliness of the passing fluid and decrease the filtering efficiency. The data in this paper provide technical support to the application in dairy filtration industry.

The current technical operational waste management in Sigli City District, starts from preparing individual and communal containers. The collection process is carried out directly and indirectly. Garbage that has been collected is transferred to a Temporary Waste Disposal Site (TPS). The processing process through composting, incineration, and recycling is only done by a small part of the population, while waste processing at large-scale TPS is not yet available, such as making compost and so on. Waste that has no economic value is transported to the Final Disposal Site (TPA). The processing aspect in the operational technical cycle is not maximally carried out. If all technical aspects of solid waste management operations can be carried out properly by the District Government of Sigli City, the generation of residential waste can be minimized. The residual waste generation in Sigli City reaches 13,887 m3 / day. This study aims to analyze the effect of technical operational aspects on waste generation in settlements, and identify solutions for handling waste generation. This research uses quantitative methods through questionnaires and qualitative methods through observation and interviews. Respondents were aimed at residents of the City of Sigli as many as 100 people. The results showed that the operational technical aspects that had a significant effect on waste generation were the aspects of container, collection, removal, transportation, and final disposal aspects. The solution for handling waste generation in the container aspect needs to procure individual waste containers and communal trash containers, on the collection aspect it is necessary to implement collection through street sweeping patterns in public areas, as well as socializing to the community to be able to participate in sorting waste that has economic value, in this aspect. for relocation, it is necessary to provide a location and TPS facility in a village that does not yet have a TPS, in the transportation aspect it is necessary to conduct socialization to waste collectors from city cleanliness institutions, to meet the requirements for transportation equipment, and in the aspect of final disposal it is necessary to carry out gas processing, and provide a location that is far from settlements for landfill development.

Successful pig farming needs the best conditions of cleanliness in the housings. The present study examined for the first time whether a robot scraper usually applied in dairy farming is usable in sow housings for cleaning the slatted floors and improving hygiene and thus animal welfare. For evaluating the suitability of the robot scraper with regard to the cleaning performance (polluted surface area and occluded slots), the whole housing area was divided into score-squares, which were individually scored at defined intervals. Selected excrement quantities removed by the robot were weighed. In order to assess the animals’ interactions with the robot scraper, their behaviour towards the device was observed. Although the faeces of pigs had a firmer consistency than bovine excrement, excrement quantities of up to 1.4 kg m−2 were almost completely removed. Even 6 h after the cleaning its effect was still visible. Dry-cleaning led faster to nonslip surfaces for the sows than wet-cleaning. Within half an hour of observation, up to 8.2 of 120 sows were occupied with the robot scraper, but without harming it. The use of robot scrapers in pig housings is recommended, although slight technical modifications should be made to the robot scraper.

Objective Maternal and newborn mortality rates are high in peri-urban areas in cities in Kenya, yet little is known about what drives women’s decisions on where to deliver. This study aimed at understanding women’s preferences on place of childbirth and how sociodemographic factors shape these preferences. Methods This study used a Discrete Choice Experiment (DCE) to quantify the relative importance of attributes on women’s choice of place of childbirth within a peri-urban setting in Nairobi, Kenya. Participants were women aged 18–49 years, who had delivered at six health facilities. The DCE consisted of six attributes: cleanliness, availability of medical equipment and drug supplies, attitude of healthcare worker, cost of delivery services, the quality of clinical services, distance and an opt-out alternative. Each woman received eight questions. A conditional logit model established the relative strength of preferences. A mixed logit model was used to assess how women’s preferences for selected attributes changed based on their sociodemographic characteristics. Results 411 women participated in the Discrete Choice Experiment, a response rate of 97.6% and completed 20,080 choice tasks. Health facility cleanliness was found to have the strongest association with choice of health facility (β = 1.488 p<0.001) followed respectively by medical equipment and supplies availability (β = 1.435 p<0.001). The opt-out alternative (β = 1.424 p<0.001) came third. The attitude of the health care workers (β = 1.347, p<0.001), quality of clinical services (β = 0.385, p<0.001), distance (β = 0.339, p<0.001) and cost (β = 0.0002 p<0.001) were ranked 4th to 7th respectively. Women who were younger and were the main income earners having a stronger preference for clean health facilities. Older married women had stronger preference for availability of medical equipment and kind healthcare workers. Conclusions Women preferred both technical and process indicators of quality of care. DCE’s can lead to the development of person-centered strategies that take into account the preferences of women to improve maternal and newborn health outcomes.

Patient satisfaction is valid indicator for measurement of service quality. Patient’s opinions are important because dissatisfaction suggests opportunities for improvement of health services in the hospital. The objective of this study was to assess the patient satisfaction with hospital services. Descriptive survey study design was adopted for this study .The population of the study was the clients who have been inpatient in Tribhuvan University Teaching Hospital (TUTH) in Kathmandu. Non probability purposive sampling technique was used and 222 patients was selected through face to face interview using a structured and semi-structured questionnaire. Data was collected from 15th June to first October 2013. The data were analyzed by using descriptive statistics such as frequency, percentage, mean and standard deviation. Using Shapiro-Wilk test for normality. The result shows that on an average patients had higher satisfaction in technical skills (mean score± SD 3.78±0.33) followed by hospital policy (3.37±0.43), accessibility skill (3.33±0.43), interpersonal skill (3.31±0.36) and least satisfied with room service of the hospital (mean: 2.58±0.29). Based on the study finding, it is concluded that overall patient satisfaction was good regarding the quality of health care services of TUTH. Among the different domains of patient satisfaction, respondents were highly satisfied with technical skill of the nurses and doctors. Although the overall services provided by TUTH are satisfactory it is necessary to improve the room services which include overall cleanliness and comfort of the patient.

Due to the increasing demand of energy consumers for high-quality, energy-intensive sources of electricity generation with a high EROI index, the implementation of tidal power plant projects is becoming increasingly attractive. At the moment, there are more than 100 stations in the world where the technical realization of TPP projects is possible. Until recently, cheap and seemingly limitless fossil energy allowed most of society to ignore the importance of the contribution of alternative sources of energy generation such as PES, but now their demand is increasing. The implementation of TPP construction projects contributes to the sustainable development of coastal towns and makes a signifi cant contribution to the energy balance of the system. The energy potential of tidal energy is quite large and comparable to the energy potential of the rivers of the Globe. Compared to river energy, the energy of tides and wind waves is low-potential, and therefore in most cases more expensive. It is worth noting that the advantage of tidal energy is environmental cleanliness, reducing the likelihood of fl ooding of adjacent territories and the absence of changes in the coastal landscape.

Tourism in Tunisia generates large amounts of solid waste, especially during the summer, and doubles the amount in most big tourism cities like Hammamet, which makes its management more complicated. Municipalities lack the financial means to ensure sustainable solid waste management (SWM) in tourist areas and need an intervention from all actors to reduce financial and technical pressures and implement sustainable solutions. This paper presents a descriptive research method that focuses on an analysis of the current SWM concept in tourism areas in Tunisia and proposes new sustainable organizational and financial models. These are based on the collaboration of different stakeholders at both national and local levels; and supported by extending the responsibility of the producer through the creation of a new system operator to take charge of the organization and financing of packaging disposal and recycling activities. In addition, the extension of the recovered material for recycling through extended producer responsibility (EPR) could support the system. The performance of current SWM shows that it has failed to ensure the cleanliness of tourism destinations is sustainable. Tunisia generates 2.8 million tons of municipal solid waste (MSW), between 20% to 30% of which are recyclable materials. The current system for packaging in Tunisia (ECO-Lef) only collected 3400 tons in 2018 compared to 15,800 tons in 2010, and the total recycling rate in the country does not exceed 5%, which makes the waste management system inefficient and unsustainable. Proposed solutions should be supported by legal and technical interventions, such as waste prevention, minimization, sorting at source, and the provision of education programs for citizens and tourism establishments.

The Korean government has announced plans to supply electrified buses to achieve decarbonization in the transportation sector and to create next-generation growth engines. Although a multitude of technical and political studies have been conducted to support the successful introduction of electrified buses, studies on the attitudes and perceptions of passengers toward electrified buses remain insufficient. To evaluate the perceptions and preferences of potential passengers toward the specific attributes of electrified buses, this study performed an online survey (N = 586) that includes people who had experienced travel on public buses. Values of the relative importance of eight different attributes—safety, ride comfort, environmental friendliness, exterior design, cleanliness, crowding, seat comfort, and convenience getting on/off—were evaluated using the best-worst scaling method. The results showed that safety (share of preference: 41.3%) was the most important attribute when using electrified buses. This was followed by eco-friendliness (14.3%) and ride comfort (13.6%). On the other hand, the least important attribute was exterior design (1.8%). Gender differences were also observed in the valuation of certain attributes among the passenger preferences toward electrified buses. The results of this study contribute to the development of strategies for the wide-spread adoption of electrified buses and provide a stepping-stone to a more sustainable public transportation system.
