Matongera, Trylee Nyasha. "The effects of relief food aid on food production and consumption patterns of communal farmers in Chigodora community, Case study: Zimbabwe." Review of Social Sciences 2, no. 3 (March 31, 2017): 24. http://dx.doi.org/10.18533/rss.v2i3.73.
Full textAbstract:
<p>The research study focuses on the effects of relief food aid on food production and consumption patterns of communal farmers in Chigodora Ward 15, Mutare District. The researcher adopted a descriptive research design. Data collection instruments used in this research study included questionnaires, interviews as well as published documents. Questionnaires targeted households in selected villages. The researcher used a cluster sampling strategy in selecting villages and random sampling technique was used to select households from the selected villages. Interviews targeted key informants such as the Agritex Extension Officer, Mutare Rural District Council Social Services Director, and Chitakatira Health Care leader, Ward 15 Councilor, Plan International Selection Director and The Village Heads. Key informants were selected using purposive sampling technique. The researcher found out that relief food aid beneficiaries in Chigodora Ward 15 receive maize, beans, cooking oil and porridge on a monthly basis. Plan international is the only humanitarian organization which supplies food in the community. Since the involvement of food aid agencies in Chigodora, production of indigenous crops such as finger millet, sorghum and rapoko decreased. New crops such as peas are now grown. The major factors driving the persistence of relief food are HIV and AIDS, climate change, lack of fair distribution of farming inputs, the restructuring of the agricultural system and dependency syndrome. Short term impacts of relief food aid on food production and access include impacts on local taste, promotes laziness and compromises access to local foods. Long term impacts mentioned were, overall decrease in food production, disincentives on farmers to produce and exposure to low quality and unsafe products. The suggest the government of Zimbabwe needs to adequately assist and empower communal farmers to produce enough food from their fields through modern technologies as well as providing farmers with loans for inputs such as fertilizers, pesticides and equipment to improve productivity.</p><p> </p>

The increasing in the world population has continuously increased the energy demand. As an effective fuel, petroleum has been serving the world to meet its energy needs. Continued use of petroleum sourced fuels is widely recognized as unsustainable because of depleting supplies and all the environmental issues around its use could be responsible for a major deficit in the future. Thus, the development of alternative energy sources, are to be welcomed. Biodiesel, as an alternative fuel, has many benefits. It is biodegradable, non-toxic and compared to petroleum-based diesel, has a more favorable combustion emission profile, such as low emissions of carbon monoxide, particulate matter and unburned hydrocarbons. In brief, these merits make biodiesel a good alternative to petroleum based fuel. The use of alternative feedstock as waste cooking oils (WCO), bovine fats and microalgae oil for biodiesel production has some advantages. It is cheaper than edible vegetable oils and it is a way to valorize a sub-product. Nevertheless, these oils has some contaminants, which can reduce the quality of biodiesel, a problem that was solved by testing different operating conditions and equipment designs for each stage of processing. The technological assessment of this process was carried out to evaluate their technical benefits, limitations and quality of final product. In this work biodiesel was produced by an alkali-catalyzed transesterification, a reaction involving the WCO feedstock and an alcohol to yield fatty acid alkyl esters (biodiesel) and glycerol. The evaluation of quality from raw materials and final biodiesel was performed according to standard EN 14214. Results show that all parameters analyzed meet the standard and legislation requirements. This evidence proves that in those operating conditions the biodiesel produced from WCO, bovine fats and microalgae can substitute petroleum-based diesel.

Full textAbstract:
Purpose – The purpose of this paper is to examine food preparation practices of US older adults by assessing their conceptualization of food preparation methods and their routine use of food preparation methods and kitchen equipment. Design/methodology/approach – In total, 17 community-dwelling older adults used cards with names of food preparation methods and cooking equipment items to do one open sort and three closed sorts about: food preparation method classifications; food preparation method use frequency; kitchen equipment use frequency; and essential vs non-essential kitchen equipment. Descriptive statistics, cluster analysis, and qualitative thematic analysis were performed. Findings – Participants classified food preparation methods using multiple dimensions: ways to alter food, inputs, location, timing, and personal behavior. They used a wide range of food preparation methods and kitchen equipment items in routine cooking. The mean number of the 38 preparation methods sorted as used “often” was 16.5±5.0. In total, 15 of the 17 participants reported using more than 20 of the 40 equipment items “often.” The mean number of equipment items identified as “essential” was 21.5±9.3. Practical implications – Food professionals should consider access to equipment and food preparation skills and preferences when designing products and working with consumers. Addressing gaps in human and material capital may support adoption of food preparation practices. Originality/value – Food preparation method and equipment use frequency has rarely been examined from the household cook’s perspective. Using card sorts is a novel approach to examining consumer classification of an extensive list of preparation methods and kitchen equipment.

Full textAbstract:
A monomer processing reactor is a device to process used cooking oil into new substance that can be used for other applications. In this study, used cooking oil was converted to monomer via simple reactor comprised of stirrer started with laboratory scale of 2L to 5L of monomer production. A scale up process is an important process for approaching industrial scale productions. The scale up process was increased to pilot scale before it reaches to industrial scale. The reactor is designed based on lab scale process for producing monomer from used cooking oil. The most important point of the device design is to produce larger amount of monomer compared to lab scale equipment. The device can produce 15liters of monomer per production. The monomer has the same properties and quality of monomer that were produced using laboratory equipment.

Biodiesels are substitute fuel sources that can be potential replacement to fossil fuels apart from being eco-friendly owing to their carbon-neutral nature. The energy originating from nature-based resources has a premium value due to its lowest environmental impact. The strategies that protect nature are grouped under a philosophy termed as ‘sustainability’. The biodiesel ought to give net energy acquire, have ecological advantages with financially serious, and producible in enormous amounts without diminishing food supplies. The proposed study examines potential of waste cooking oil as a source of bio-diesels by collecting samples of used cooking oil from the food outlets. The characteristics of producing bio-diesel from waste cooking oil are investigated from the point of view of utilizing it on a small batch mode of 5 to 10 litre. The chemistry of transesterification is investigated by adopting computational route to design a reactor and experimentally verifying the small-scale production.

Full textAbstract:
Globally, states are obliged to prioritize quality medical care at emergency departments (EDs). Kenya is not an exception since medical care services are mainly offered in the outpatient departments. However, the quality of care in these outpatient departments has not been evaluated. The aim of this study was to investigate quality of care at EDs of public hospital in Kenya, with a focus on Bungoma County. The study evaluated the availability of infrastructure, equipment, supplies and personnel. Besides, the researcher assessed processes, protocols, and outcomes of care at the Eds in Kenya’s public hospitals. A cross-sectional study design was employed, with a sample of 10 ED in-charges and 398 patients. The participants were proportionately recruited from the EDs via probability proportional to size (PPS). Quality of the EDS was measured using the Donabedian model with structure assessed by evaluating availability of infrastructure, equipment, supplies and personnel for emergency care. Process was evaluated by measuring turnaround timelines, assessment of presence and utilization of triage systems, protocols, and guidelines. Outcomes were measured using number of admissions, deaths, left without being seen, unplanned re-attendance, and patient service experience. Data collection was based on WHO observation checklists and with the help of questionnaires. The analysis consisted of descriptive and inferential statistics. The findings revealed that infrastructure availability was 42.0% with all EDs lacking resuscitation rooms and high dependency units. Secondly, imaging rooms were in 40% of the hospitals, blood banks in 50%, and running water in 70%. Third, equipment availability was 34.7% with oxygen source, pulse oximeter, point of care ultrasound and trauma cart being available in 10%. Fourth, regular maintenance of equipment was in 52.5% of the EDs. Finally, availability of supplies for resuscitation was 52% with Supplies for airway management being the least (22%). From the study, it was apparent that trained personnel, equipment, supplies and processes such of triage systems. This has contributed to prolonged turnaround time and high re-attendance rates. There is need for provision of adequate infrastructure, equipment, personnel, and systems for emergency care in public hospitals EDs in Bungoma County to improve quality of care.

Full textAbstract:
Solid particle emissions from burning wood in three internal combustion biomass cooking stoves commonly used in southern Chile were compared. Each stove was used to show differences in sealing systems, combustion chamber shape, and heating surfaces in order to optimize biomass combustion and the energy produced at a low manufacturing cost. The influence of cooking stove design along with particle and gas emissions that resulted from the biomass combustion within the cooking stove was investigated in this study. Levels of diverse atmospheric contaminants, such as particulate matter, emission factor, NOx, CO2, and CO, and the temperature of the flue gases were determined with the Ch-28 method and UNE-EN 12815. The average emission of particulate matter was significantly reduced by modifying the geometry of the combustion chamber and heating surface of each stove, resulting in 5 g/h particle emissions in conventional equipment and 2 g/h in the improved equipment. In relation to gas emissions, there was a 25% maximum decrease in NOx gases and 35% in CO after modifying the heating surface of each stove. This background supports the evidence of technological improvement with high environmental impact and low economic cost for local manufacturers.

Full textAbstract:
Shortly after the outbreak of the COVID-19 pandemic, there was a need to provide protective equipment to the medical facilities whose supplies were threatened to be depleted. Just like many countries in Europe, Montenegro responded to the need for medical equipment by using the advantages of 3D printers while establishing a state network of production hubs, ensuring closed connectivity, communication, and the mutual fulfilment of personal protective equipment (PPE) demands whenever and wherever required. With the second wave of the pandemic, Montenegro rose to second place in the world with the number of coronavirus cases, which also led to an increasing number of infected medical staff. Since fever is a frequent symptom of SA+RS-CoV2 infection, a type of innovative 3D-printed thermo-sensored medical gear has been designed and tested in hospital conditions. This medical gear shaped like a bracelet, which changes color in the presence of high human body temperatures, proves to be efficient and easy to use for medical staff as well as patients.

Full textAbstract:
To prevent the spread of the COVID-19 pandemic, 2019 has seen unprecedented demand for medical equipment and supplies. However, the problem of waste treatment has not yet been given due attention, i.e., the traditional waste treatment process is done independently, and it is not easy to share the necessary information. Especially during the COVID-19 pandemic, the interaction between parties is minimized to limit infections. To evaluate the current system at medical centers, we also refer to the traditional waste treatment processes of four hospitals in Can Tho and Ho Chi Minh cities (Vietnam). Almost all hospitals are handled independently, lacking any interaction between the stakeholders. In this article, we propose a decentralized blockchain-based system for automating waste treatment processes for medical equipment and supplies after usage among the relevant parties, named Medical-Waste Chain. It consists of four components: medical equipment and supplies, waste centers, recycling plants, and sorting factories. Medical-Waste Chain integrates blockchain-based Hyperledger Fabric technology with decentralized storage of medical equipment and supply information, and securely shares related data with stakeholders. We present the system design, along with the interactions among the stakeholders, to ensure the minimization of medical waste generation. We evaluate the performance of the proposed solution using system-wide timing and latency analysis based on the Hyperledger Caliper engine. Our system is developed based on the hybrid-blockchain system, so it is fully scalable for both on-chain and off-chain-based extensions. Moreover, the participants do not need to pay any fees to use and upgrade the system. To encourage future use of Medical-Waste Chain, we also share a proof-of-concept on our Github repository.

Exercise products based on universal design, which reduce restrictions on the exercise environment and ensure convenience and safe use, are beneficial for people with a disability; however, the current universal design only considers the preferences of the general population, which is not suitable for the disabled population. This results in the exclusivity of the sports facilities and supplies for people with a disability. Consequently, we explored the components of universal design and product satisfaction by considering users with disabilities and proposed the direction for designing extended universal exercise equipment that is suitable for them. Specifically, this study focuses on developing exercise equipment for people with a disability. Based on the results from the evaluation of acceptance and satisfaction of universal sports products for people with a disability using design thinking, we suggest the following. First, it is necessary to consider safety devices for exercise products. Second, the user interface should be improved in terms of convenience. Third, the ergonomic instrument design should be improved. Finally, the instrument design should be centered on user convenience.

Objective: The purpose of this study was to identify the role of emergency department (ED) design on ED staff satisfaction and performance. Background: High patient volume, surging workloads, and violent behaviors are expected pressures for ED staff. Literature suggests the substantial role of the physical environment in the delivery of care and its role in staff and patient experiences. Nevertheless, limited studies have explored simultaneous interactions between ED physical design elements, attributes (security, wayfinding, visibility, privacy, and efficiency), and staff satisfaction or performance. Method: Interviews, surveys, visibility graph analysis, and agent simulations were employed to understand the connection between ED physical design, attributes, performance, and staff satisfaction. Results: Enhanced security, effective wayfinding, team visibility, noise reduction, adequate privacy, and accessible supplies and equipment were significant predictors of staff satisfaction and performance. Unobstructed views in waiting and triage and controlled entrances were critical for improving security. To improve wayfinding, eye-level signage, reducing surveillance obstacles, and creating direct public routes were recommended. Rectangular units with multiple perpendicularly connected corridors and linear pod arrangements enhanced movement. Including team rooms and enclosed ERs were recommended for privacy improvements. Visibility was critical for team communication and improved by including short-distanced perpendicular corridors and eliminating columns. Enhancing access to supplies or equipment and reducing noise levels improved the perception of staff efficiency. Conclusion: The findings contribute to the general body of knowledge on the impact of ED physical design on attributes that potentially improve staff satisfaction and work performance.

Full textAbstract:
A technique to monitor transesterification of waste cooking oil (WCO) is presented. The technique was developed based on analogue signal from WCO, fatty acid methyl ester (FAME) and commercial palm oil (CPO). A low-pass filter design for the photodiode was used to obtain the characteristic analog signal generated by these oil samples and the signal was correlated to absorbance spectra of the oils using data from Fourier transform infrared (FTIR) equipment. A match was made between the analogue signals of the oil samples and calibrated against the FTIR spectra at 95% confidence level. Depletion of WCO during transesterification in a batch reactor correlated with the time observed for peak yield during biodiesel production. The results of the technique are discussed as a possible way to monitor transesterification process in a batch reactor.

Students first design their own experiment using very basic equipment and supplies, which generally results in mixed, but mostly poor, outcomes. Classroom “talk and argument” is then used to determine how their experiments could be changed to gather more reliable data. The final assessment consists of both formal and subjective testing, requiring students to explain their design choices.

Full textAbstract:
The article discusses an approach to technical diagnostics of secondary power supplies for communication facilities. Diagnostics is carried out during the current repair. This takes into account the features of the object being diagnosed, which affect the process of searching for defects. The purpose of the article is to analyze possible options for the development of diagnostic support for secondary power supplies. This takes into account the metrological reliability of measuring equipment. The probability of correct diagnosis is also calculated when searching for defects during routine repairs. Practically implemented recommendations for ensuring the required values of the indicators of the maintainability of communication facilities are substantiated. The possibility and expediency of using effective methods for diagnostics of secondary power supplies of communication facilities, which consider the sources as objects with many inputs, are shown. This allows the design to take into account the requirements for the maintainability of the product. During routine repairs, the time needed to search for defects is minimized. This is done through a rational choice of diagnostic procedures. When choosing, design features and conditions for restoring performance are taken into account. The proposed block diagram of the algorithm for choosing a diagnostic option minimizes the average recovery time of an object. A specific example of using the results obtained in the development of a conditional diagnostic algorithm for the power supply unit of the exciter and the radio receiver of an average power radio station is given. It is advisable to use the results obtained in the development of diagnostic support for promising communication facilities or in the improvement of existing communication facilities without additional costs.

Full textAbstract:
Microwave technology has many current applications. It is very useful for food processing, including domestic cooking and warming-up and industrial heating and drying. It heats faster than conventional applications; however, in most cases result in non-uniform temperature distribution. Adequate cavity and equipment designs can reduce the impact of these heterogeneities and using multiples magnetrons is a possibility to mitigate hot and cold spots. Yet, the literature lacks methods to evaluate and compare multiple magnetrons designs. This study aimed to develop a procedure to evaluate the number and position of magnetrons connected to an application cavity using multiphysics modelling and simulation of the microwave distribution and heating of a food model. It was based on evaluating the electric field distribution into a selected working volume filled with air or a mixture of air-potato and the consequent effective power absorbed and temperature distribution into the air-potato medium. The assisted methodology with process simulation offers an insight into food temperature distribution, which would be very difficult to obtain experimentally or in any equipment design methodology.

When organizing the educational process in higher education institutions, safe conditions must be created that meet all the general current requirements of labor protection. The most common physical factor of adverse effects on students in classrooms are man-made electromagnetic fields around each technical means and in different configurations of the relative location of equipment. Based on the fundamental physical relations and dipole models of propagation of electric and magnetic components of electromagnetic fields using EMF LFSourse software, models of propagation of electric and magnetic fields of personal computer components were obtained. This visualized the propagation of an electric field around liquid crystal monitors, magnetic fields around personal computer system units, and uninterruptible power supplies. The result is a spatial distribution of electric and magnetic field strengths in computerized workplaces. These models allow you to streamline the relative position of personal computers in computer classrooms and other classrooms where computers are located in terms of electromagnetic safety. Detailed models of the configuration of electric and magnetic fields allow to obtain the propagation of fields around the electrical equipment of training laboratories. The example of modeling the propagation of the electric and magnetic components of the electromagnetic field of personal computer components shows the possibility of providing safe configurations of individual workplaces and many workplaces in computer classrooms. It is expedient to create models of propagation of other physical factors of technogenic origin – sound, infrasound, anomalous distribution of air ion concentrations, etc. Modeling allows you to place equipment in training laboratories at the design stage, adhering to safe conditions in the organization of the educational process.

Designing or renovating a physical environment for healthcare is a complex process and is critical for both the staff and the patients who rely on the environment to support and facilitate patient care. Conducting a simulation-based mock-up evaluation as part of the design process can enhance patient safety, staff efficiency, as well as user experience, and can yield financial returns. A large urban tertiary care center located in Vancouver, Canada followed a framework to evaluate the proposed design template for 28 universal operating rooms (ORs) included within the OR Renewal Project scope. Simulation scenarios were enacted by nursing staff, surgeons, anesthesiologists, residents, radiology techs, and anesthesia assistants. Video and debriefing data were used to conduct link analyses, as well as analyses of observed behaviors including congestions and bumps to generate recommendations for evidence-based design changes that were presented to the project team. Recommendations incorporated into the design included relocating doors, booms, equipment, and supplies, as well as reconfigurations to workstations. These recommendations were also incorporated into the mock-up and retested to iteratively develop and evaluate the design. Findings suggest that incorporating the recommended design changes resulted in better room utilization, decreased congestion, and enhanced access to equipment.

In many industries and medical power system applications, dual power source design is often used to ensure that the equipment runs continuously, even when the main power supply is shut down. However, the voltage feedback between two independent power supplies and low loss output are critical issues for the system energy dissipation. Without using a dedicated chip, a new mutual blocking control technology is proposed in this paper to effectively solve the problem of voltage feedback existing in the conventional dual power system. In addition, without adding much hardware cost, the proposed dual power switch design can completely avoid voltage feedback and achieve a low voltage loss of about 30 mV when the load current is less than 0.5 A.

Background: Lassa fever is endemic in Nigeria and health care workers are at a high risk of contracting and transmitting the infection. This study compares Lassa fever prevention practices among health care providers in public and private Primary Health Care facilities in Jos.Methods: The study used a comparative cross-sectional design to study health care workers in 29 Primary Health Care facilities selected using a two-stage sampling technique. All health care workers who attended to patients were interviewed using a semistructured interviewer-administered questionnaire. Data were analysed using Statistical Package for Social Sciences version 23 and a p-value of ≤ 0.5 was considered statistically significant.Results: Majority of the respondents had neither received on-the-job training on Lassa fever prevention (91.9%) nor Universal Standard Precautions (88.7%). Private Primary Health Care facilities had better supplies and equipment for Lassa fever prevention compared to their public counterparts. Majority (65.8%) of respondents had poor Lassa fever prevention practices and this was worse in the private (75.4%) than the public (55.6%) facilities. No facility met all the requirements for Lassa fever prevention. Training had a statistically significant association with good practice among public Primary Health Care facilities. Conclusion: Noncompliance with Lassa fever prevention practice is still common in Primary Health Care facilities. This is worse in private facilities. Continuous training and improved supplies of materials and equipment are necessary for effective Lassa fever prevention among these health care providers.

Abstract In conditions of reduced freshwater reserves, the problem of its extraction of transportation and storage requires scientific justification of the relevant technical and technological solutions and the development of technical means. The article offers a mobile drinking water module. The design of the module provides for its placement in a thermally insulated container including a system of heating, power supply, distribution, filling and disinfection of water. For the development of the drinking water module, modern technical solutions are used to reduce the heat loss of the tank due to the use of a composite material and a cable of electric heater system. Reduction of microorganism propagation activity in water is provided by ultraviolet treatment and disinfection through ultraviolet gate. The design of the container is designed taking into account the possibility of its transportation in all modes of transport as a separate cargo unit. With the device of belts for loading and unloading. For loading into cars without the use of crane equipment, extendable outriggers are installed in the container, which can be used to install the container on water distribution sites. Mobility of the drinking module is ensured by the inclusion of a diesel generator unit in its composition. The tank of the module is made of stainless steel ensuring the safety of water without the formation of harmful impurities in it, and the coating of the tank with a composite material creates the effect of a thermos. The function of filling and distributing water from the tank is implemented using a distribution column with a vortex pump of a system of shut-off valves and hoses for supplying water. Experimental studies of mobile module operation have been performed. It was established that in order to maintain the water temperature in the tank at 10 ° C at an ambient temperature of minus 30 ° C, the heating system should not be switched on. The innovative design of the heat insulated layer reduces the thermal conductivity of similar water storage tanks made of traditional materials by 4 times. The proposed design of the mobile drinking module provides the possibility of creating clean water reserves for catering and household supplies.

Full textAbstract:
Digester corrosion is costly because of repairs, replacement of components and upgrade of materials, and losses in connection with unplanned outages. Risks to life and property also are significant, especially if catastrophic failure of pressurized equipment occurs. From the 1980s to present, corrosion problems in many pulp and paper mills worldwide have been intensifying, some resulting from materials and design aspects of the digesters themselves or later process modifications. The main focus of this study is the corrosive behavior of continuous digesters with modified processes. We discuss actual corrosion cases in two continuous digesters at a pulp mill in Brazil and the protection measures adopted. Results of electrochemical testing, metallurgical analyses, corrosivity testing, and field inspections are discussed. In one case, a carbon steel digester experienced rapid thinning on its top sections, with wall loss of 5 mm over 30 months following a process change. In the second case, also following a process change, a unique, type 316 stainless-clad continuous digester was found to have an altered electrochemical profile, indicating prospective corrosion hazards. This prompted studies and protective measures that are unique for stainless cooking vessels. The risks to carbon or austenitic stainless steel digesters running on modern cooking processes are shown to be significant. The effectiveness of the protective technologies, and their compatibility, was proved, and the need to consider these technologies upon cooking retrofit projects was established.

SMK N 1 Koto XI Tarusan is one of the SMK’s that develops new study programs namely Teknik Audio Video (TAV), one of the goals is to prepare the students to have the skills to enter employment in companies engaged in electronics in addition to continuing to the level of higher education. Department of Audio Video Engineering is more directed to the electronics field, but in all teaching and learning activities especially practical activities using equipment related to electricity, such as power supplies. But they do not have good knowledge about power supplies because power supplies are basic knowledge of electricity that is not specifically studied in the field of Audio Video Engineering. Thus, teachers must be equipped with adequate skills, so that these skills can be transferred to their students. The provision of skills for these teachers is carried out by providing training in making power supplies with variable outputs. The method of conducting training is direct practice, with 3 stages. The first stage was that participants were given knowledge about power supply theory, about how to design power supply circuits and calculate component and design requirements. The second or core stage, the trainees did the practice of making layouts, the practice of designing the power supply, the practice of calculating the value of the components needed, and assembling the power supply itself such as making a PCB layout, and making a variable power supply trainer. While, the third stage or the final stage is troubleshooting to test the power supply that is made to function properly/not. The training that was carried out was also analyzed with several indicators to see whether the training provided an increase in skills to the participants/not. From the training that has been carried out, the trainees can make 10 sets of 0-30 Volt variable power supplies that can be functioned properly. The training can also improve the participants' skills which are analyzed from several indicators: learning, behavior, reaction, and results. Testing with these indicators shows that the implementation of the training has provided profound benefits and is very helpful in improving the participants' self quality.

AbstractObjectiveTo identify ways that the built environment may support or disrupt safe doffing of personal protective equipment (PPE) in biocontainment units (BCU).DesignWe observed interactions between healthcare workers (HCWs) and the built environment during 41 simulated PPE donning and doffing exercises.SettingThe BCUs of 4 Ebola treatment facilities and 1 high-fidelity BCU mockup.ParticipantsA total of 64 HCWs (41 doffing HCWs and 15 trained observers) participated in this study.ResultsIn each facility, we observed how the physical environment influences risky behaviors by the HCW. The environmental design impeded communication between trained observers (TOs) and HCWs because of limited window size or visual obstructions with louvers, which allowed unobserved errors. The size and configuration of the doffing area impacted HCW adherence to protocol, and lack of clear demarcation of zones resulted in HCWs inadvertently leaving the doffing area and stepping back into the contaminated areas. Lack of standard location for items resulted in equipment and supplies frequently shifting positions. Finally, different solutions for maintaining balance while removing shoe covers (ie, chair, hand grips, and step stool) had variable success. We identified the 5 key requirements that doffing areas must achieve to support safe doffing of PPE, and we developed a matrix of proposed design strategies that can be implemented to meet those requirements.ConclusionsSimple, low-cost environmental design interventions can provide structure to support and improve HCW safety in BCUs. These interventions should be implemented in both current and future BCUs.

At the start of the COVID-19 outbreak, many countries lacked personal protective equipment (PPE) to protect healthcare workers. To address this problem, open design and 3D printing technologies were adopted to provide much-in-need PPEs for key workers. This paper reports an initiative by designers and engineers in the UK and China. The case study approach and content analysis method were used to study the stakeholders, the design process, and other relevant issues such as regulation. Good practice and lessons were summarised, and suggestions for using distributed 3D printing to supply PPEs were made. It concludes that 3D printing has played an important role in producing PPEs when there was a shortage of supply, and distributed manufacturing has the potential to quickly respond to local small-bench production needs. In the future, clearer specification, better match of demands and supply, and quicker evaluation against relevant regulations will provide efficiency and quality assurance for 3D printed PPE supplies.

AbstractThe current study evaluated the effects of dietary roughage:concentrate (R:C) ratios and water supply on the carcass characteristics and yield of lambs. Forty Santa Inês crossbred lambs with an average body weight (BW) of 19 ± 2.8 kg were evaluated in a completely randomized design with a 2 × 2 factorial arrangement consisting of two proportions of roughage and concentrate (30:70 and 70:30) and two levels of water supply (ad libitum and restricted to 0.5). The animals were slaughtered at an average weight of 28 ± 31 kg. Centesimal composition, colour parameters (L*, a* and b*), shear force, cooking losses and pH were determined on the Longissimus lumborum muscle. There was no interaction effect between the R:C ratio and water supply on the evaluated variables. Total BW gain, average daily gain and final BW were affected by water restriction and R:C ratio. Water restriction reduced total BW gain, average daily gain and final BW. No effect of water restriction was detected on slaughter weight, centesimal composition, colour variations, shear force, pH, weight or yield of carcass. No effect of water restriction and diets was observed on the cuts, except for neck weight. Carcass weight and yield were affected by the R:C ratios. Restricting the water supply to 0.5 does not affect the carcass weight or yield of Santa Inês crossbred lambs or their meat quality characteristics (centesimal composition, colour, shear force and pH measurements). A higher proportion of concentrate in the diet results in heavier hot and cold carcass weights.

The current level of development of robotic systems of armaments, military and special equipment is characterized by an accelerated transition to their construction on a modular basis. Due to this relatively small nomenclature of initial blocks-modules of lower levels can provide a large variety of the type of land-mobile robotic complexes of specialized functionality. There is an opportunity to quickly adapt the necessary robotic military equipment to specific combat conditions, which guarantees the reliable performance of the assigned combat missions. It is proposed to equip the transport platforms for robotic systems of armament, military and special technics by electromechanical engines on the basis of autonomous drive modules with driven forced electric motors on the basis of rare-earth neodymium permanent magnets. At the same time, record high performance transshipment capacity is achieved, which dramatically increases the ability to overcome difficult road impediments. The article deals with the design features of modular transport platforms for modern robotized weapons, military and special equipment systems, which are conditioned by the need for reliable delivery of weapons, ammunition, equipment, foodstuffs and medical supplies to the personnel on the line of contact with the enemy in difficult geoclimatic conditions. It is shown that the necessary quality of realization of the assigned of combat tasks is ensured by the application of the installation on the platforms of autonomous electromechanical drives of driving wheels.

Full textAbstract:
This paper presents an innovative concept of using air-cycle technology for the development of a microclimate cooling device for use by soldiers in the battlefield. The device is an integrated heat engine and heat pump which supplies air at a prescribed temperature and humidity for personal cooling of a soldier wearing protective ensembles, generates electrical energy to power communication equipment, and produces drinking water by condensing atmospheric moisture which may be very useful in desert warfare. It consists of a centrifugal compressor, two turbines or expanders, a combustion chamber, three heat exchangers, a water separator, and an electric generator. Atmospheric air is used as the working fluid in both the engine and cooling loops and diesel is used as the fuel for combustion. A detailed thermodynamic analysis and design optimization was performed. It was found that the system efficiency increases with operating pressure ratio, attains a maximum, and decreases with further increase of pressure ratio. The system efficiency was found to be also dependent on the air-fuel ratio, and the maximum efficiency was found to occur at a specific air-fuel ratio, for any given pressure ratio. The optimum operating condition determined from the thermodynamic analysis was used to outline a detailed design of the system.

The management structure that the paper discussed is from the equipment maintenance unit. The structure is the base and support system of the unit. The optima design of the structure possess the basal position in unit management .Based on the theory of entropy, this paper analyses the influence of system management structure on the system information flow. It evaluated the order degree of system management structure in view of information, introduced two concepts: time- effect and quality of information flow and established the Time Effect-Quality Model (TEQM). With TEQM, it is possible to optimize and quantitatively evaluate the system management structure. In addition, the paper also supplies detailed calculating steps of order degree of system management structure, and provides an example at the end.

Full textAbstract:
Monitoring affordability of drinking water services is constrained by data gaps from traditional approaches that rely on cross-sectional data from infrequent, nationally representative surveys. Estimates of income or expenditure ratios spent on accessing a main source of drinking water are poorly equipped to reflect affordability in rural contexts where poor people often resort to multiple sources of varying costs, quality and distance to cope with unreliable or absent water supplies. Here, we present findings from an 18-week water diary study that documented daily water choices and expenditures of a stratified sample of 120 households in coastal Bangladesh. This intensive, longitudinal monitoring is supported by household surveys, water infrastructure mapping, hydrogeological analysis of salinity, automated rainfall measurements and interviews with diary participants. We identify five water expenditure typologies, ranging from those who always rely on unpaid and often poor-quality sources like shallow tubewells, pond sand filters and rainwater, to those who purchase vended water for drinking and cooking all year-round, spending 3–7% of total household expenditure. These behavioral dynamics are shaped by environmental, infrastructure and cultural factors, with household wealth being a weak indicator of behavior. We conclude that affordability measures should recognize the quality of service available and chosen by users across seasons, rather than being fixated on income or expenditure ratios for a main source. Measuring the latter without considering the former impedes the design of service delivery models appropriate for providing safe and reliable water supplies, at costs that users and society are willing to bear and sustain.
