Abstract:

An early and accurate diagnosis of Candida albicans is critical for the rapid antifungal treatment of candidemia, a mortal bloodstream infection. This study demonstrates viscoelastic microfluidic techniques for continuous separation, concentration, and subsequent washing of Candida cells in the blood. The total sample preparation system contains two-step microfluidic devices: a closed-loop separation and concentration device and a co-flow cell-washing device. To determine the flow conditions of the closed-loop device, such as the flow rate factor, a mixture of 4 and 13 μm particles was used. Candida cells were successfully separated from the white blood cells (WBCs) and concentrated by 74.6-fold in the sample reservoir of the closed-loop system at 800 μL/min with a flow rate factor of 3.3. In addition, the collected Candida cells were washed with washing buffer (deionized water) in the microchannels with an aspect ratio of 2 at a total flow rate of 100 μL/min. Finally, Candida cells at extremely low concentrations (Ct > 35) became detectable after the removal of WBCs, the additional buffer solution in the closed-loop system (Ct = 30.3 ± 1.3), and further removal of blood lysate and washing (Ct = 23.3 ± 1.6).

Abstract:

Modern textronic RFID transponders offer a lot of new possibilities for household appliances designers. Possibility to implement new functions is most evident in clothes washing and ironing techniques, where the information stored in the memory of the RFID transponder sewn into the textiles can be used to choose the most appropriate ironing program for a given type of fabric or to select the best washing program for different clothes placed in a drum of washing machine. The purpose of the work was to propose, design, and develop a laboratory stand to demonstrate usage of RFIDtex transponders in a washing machine. The developed device enabled simulation of the presence of textiles equipped with RFIDtex transponders in a washing machine drum. A set of measurements of the constructed device readout efficiency of textronic transponders placed in the drum was also performed. The device firmware, which manages multiple data readings from tags inside the drum for the performed by integrated RWD (read/write device), was also prepared and implemented. This allowed the efficiency of the identification of textiles equipped with RFIDtex transponders to be increased. RFIDtex transponders can also be used in the future to provide precise information about textiles to the washing machine. Based on this information, device will be able to reduce power consumption.

Abstract:

The storage of red blood cells (RBC) results in increased concentrations of plasma free hemoglobin, potassium, glucose, and lactate, among other undesirable substances. These concentrations continue to increase as RBC products age and can cause deleterious effects to the patient. In the setting of cardiac surgery, the autotransfusion devices are routinely used to wash blood that is shed from the surgical site. These devices could also be used to wash stored RBC units obtained from the blood bank. The objective of this study was to compare the product created by washing a unit of RBCs with the AutoLog autotransfusion device in the operating room to the washed products from a standard cell washer in the blood bank. Eleven outdated RBC units (stored for >42 days at 4°C) were split in half. One half was washed using the Medtronic AutoLog device; the other half was washed using the blood bank’s Cobe 2991 Cell Processor. Analytes were measured on samples from the unwashed parent unit and from the washed daughter units. The parameters measured included hematocrit, free hemoglobin, lactate, lactate dehydrogenase (LDH), potassium, glucose, and pH. When compared to the original untreated RBCs, the glucose, lactate, and potassium levels were decreased when washed in an autotranfusion device. Additionally, the free hemoglobin and LDH levels were significantly lower with the Medtronic Autolog cell saver than in the COBE 2991 Cell Processor. Washing the RBC donor units in an autotransfusion device prior to transfusion can effectively attenuate the increases seen in glucose, potassium, free hemoglobin, and LDH associated with RBC storage lesion.

Abstract: The world faced so many problems during the Covid-19 pandemic. Washing our hands was an integral part of preventive measures of the Covid-19. But it is found that it wastes so much water in the world. Many people do not have access to clean drinking water and face water scarcity. The sanitizer is also used by many people. But excessive use of sanitizer with high alcohol concentration leads to dry, itchy skin. The indirect consumption of sanitizer through the hands leads to the risk of other health conditions. In this proposed system, fog making technology is used for dispensing sanitizer. So that only the required quantity of sanitizer is dispensed and it covers the entire surface area of hands, guaranteeing the disinfection of hands. This system is proposed to reduce water usage by around 90%. It also saves 20-30% of the water that rolls over the hands while washing the hands and also the water required for washing hands. This system did not completely replace the handwashing method but it helped in saving a remarkable quantity of water. It also helped in preventing skin diseases and other potential health hazards.

Abstract:

Background: During the Covid-19 pandemic, the risk is high for people to contact the virus. The risk multiplies at crowded places. To combat the problem in a country like Bangladesh, where hygienic practices are poor, we manufactured a user-friendly hand washing device. The public use of this device will ensure a hygienic lifestyle for people. Methods: Manufactured in Bangladesh’s Cumilla and unveiled on August 15, 2020, this “Foot Press Hand washing Device” is a system requiring only a foot pressing to operate. It was designed based on the hydraulic pressure of the air pump having two operational aspects- soap ejection and water outlet. An online cross-sectional survey on 450 individuals in three cities and a face-to-face survey in a Bangladesh village were conducted to assess users’ satisfaction. Results: A total of 73.1% and 70.1% respondents in two surveys used a hand washing device in the past six months, 71.8% and 73.8% prioritized 20-second hand washing, 37.6% and 68.7% voiced importance of health hygiene against Covid-19. A total of 71.0% and 78.1% found the device unique while 71.2% and 74.7% believed it useful against Covid-19, 68.0% and 73.3% believed it suitable for rural people, 71.8% and 73.6% believed that it could be placed in a crowded place, 44.4% and 65.1% found it user-friendly for rural people. Conclusions: The device helps restrict virus transmission by washing hands with soap water in public places. This low-cost device can be produced using locally available materials. Future studies are needed to assess its effectiveness to prevent Covid-19 and hygiene-related infections.

Abstract:

At present, many places are seriously short of freshwater resources. Thus, saving water is the universal responsibility of contemporary citizens. Now faucet products such as ordinary washing nozzle, kitchen nozzle, face-washer nozzle, bathtub nozzle and washing machine nozzle are widely used in urban and rural households. Most have poor water-saving abilities, and much water is wasted through daily washing. Our bubble-type water-saving device is a brand-new water-saving device with a simple structure and low cost. It uses the Bernoulli principle and the bubble atomizing principle to inhale air naturally in water flow to atomize water flow. It can help achieve more than 50% water-saving efficiency in daily washing behavior.

Abstract:

The pH of water is different in different areas. So, the washing machines which are based on Fuzzy Logic Controller being used in different areas are deprived of useful results because these machines cannot detect the pH of water. When pH of water is other than 7, more detergent and washing time for laundry is consumed. The proposition of the paper is that neutral water (pH = 7) should be used in washing machines. It will reduce the washing time. In this way, energy and washing time can be saved. The impersonate results and the action of the aforementioned device have been done by fuzzy logic toolbox using MATLAB.

Abstract:

This article concerns research on washing effectiveness of a high-pressure washing device. Three types of investigations were carried out: Laboratory tests on washing of crushed-stone and gravel aggregate, as well as pilot-scale tests on crushed-stone aggregate. Laboratory tests were conducted for four changeable parameters and pilot-scale investigations for three parameters. All tests were performed based on factorial experiment procedure. For each type of material there was built a model based on multiple regression method. Results of investigations showed that operating pressure in the washer has the highest effect on obtained washing effectiveness, measured as a degree of dust impurities’ removal from feed. The second parameter with the highest impact on washing process effectiveness was the maximum particle of feed, and its relationship to the obtained washing effectiveness appeared inversely proportional. For the crushed-stone aggregate the susceptibility of washing also appeared significant in models.

Abstract:

Background. In 2013, the World Health Organization reported a shortage of 17 million red blood cell units, a number that remains growing. Acts to relieve this shortage have primarily focused on allogeneic blood collection. Nevertheless, autologous transfusion can partially alleviate the current pressure and dependence on blood banking systems. To achieve this, current gold standard autotransfusion devices should be complemented with widely available, cost-efficient, and time-efficient devices. The novel HemoClear cell salvage device (HemoClear BV, Zwolle, Netherlands), a gravity-driven microfilter, potentially is widely employable. We evaluated its performance in the cardiac postoperative setting compared to the centrifugal XTRA™ autotransfusion device. Methods. In a split-unit study (n = 18), shed blood collected 18 hours after cardiothoracic surgery was divided into two equal volumes. One-half was processed by the XTRA™ device and the other with the HemoClear blood separation system. In this paired set-up, equal washing volumes were used for both methods. Washing effectivity and cellular recovery were determined by measuring of complete blood count, free hemoglobin, complement C3, complement C4, and D-dimer in both concentrate as filtrate. Also, processing times and volumes were evaluated. Results. The HemoClear and XTRA™ devices showed equal effectiveness in concentrating erythrocytes and leucocytes. Both methods reduced complement C3, complement C4, and D-dimer by ≥90%. The centrifugal device reduced solutes more significantly by up to 99%. Free hemoglobin load was reduced to 12.9% and 15.5% by the XTRA™ and HemoClear, respectively. Conclusion. The HemoClear device effectively produced washed concentrated red blood cells comparably to the conventional centrifugal XTRA™ autotransfusion device. Although the centrifugal XTRA™ device achieved a significantly higher reduction in contaminants, the HemoClear device achieved acceptable blood quality and seems promising in settings where gold standard cell savers are unaffordable or unpractical.

Abstract:

ABSTRACT The market for tea drinks as healthy beverages has been steadily expanding, and ready-to-drink beverages in polyethylene terephthalate bottles have been popular. To more rapidly and accurately test tea beverages bottled in polyethylene terephthalate for microbial contamination, a newly developed filtration device and a washing method with a commercial bioluminescence assay were combined to detect low numbers of bacterial spores, fungal conidia, and ascospores. Washing buffers were formulated with nonionic detergents from the Tween series. Commercially available tea beverages were used to evaluate the filtration capacity of the filtration device, the effect of washing buffers, and the performance of the assay. The assay was tested with serially diluted suspensions of colonies of two bacterial strains, spores of three Bacillus strains, conidia of five fungal strains, and ascospores of four fungal strains. The filtration device enabled filtration of a large sample volume (100 to 500 ml), and the washing buffer significantly decreased the background bioluminescence intensity of tea samples when compared with the no-washing method. Low numbers (1 to 10 CFU/100 ml) of the tested strains of bacteria were detected within 8 to 18 h of cultivation, and fungi were detected within 24 to 48 h. Furthermore, a whole bottle (500 ml) of mixed tea was filtered through the filtration device and microbes were detected. This method could be used for quality control of bottled beverages without preincubation.

Abstract:

A major challenge faced by hospitals is to provide efficient medical services. The problem studied in this article is motivated by the hospital sterilization services where the washing step generally constitutes a bottleneck in the sterilization services. Therefore, an efficient scheduling of the washing operations to reduce flow time and work-in-process inventories is of great concern to management. In the washing step, different sets of reusable medical devices may be washed together as long as the washer capacity is not exceeded. Thus, the washing step is modeled as a batch scheduling problem where washers have nonidentical capacities and reusable medical device sets have different sizes and different ready times. The objective is to minimize the sum of completion times for washing operations. The problem is first formulated as a nonlinear integer programming model. Given that this problem is NP-hard, a genetic algorithm is then proposed to heuristically solve the problem. Computational experiments show that the proposed algorithm is capable of consistently obtaining high-quality solutions in short computation times.

Abstract:

For the study of soil erosion it is important to set up the experiments well. In the experimental design one of the key factors is the choice of the measurement device. This is especially important when one part of the erosion process needs to be isolated, such as for splash erosion. Therefore, the main aim of this research is to list the general characteristics of the commonly used splash erosion devices and to discuss the performance, to be able to relate them, and make suggestions regarding their use. The devices we selected for this comparative comparison were: the splash cup, funnel, Morgan tray, Tübingen cup, tower, and the gutter. The devices were tested under the same conditions (rainfall characteristics, slope, and soil type) to assess their hydrological response under different intensities of simulated rainfall. All devices were installed on a sloping plot (10°) with sandy soil, and were exposed to 10 min. of simulated rain with intensities ranging from 60 to 172 mm/h to measure the splashed sediment, and to describe problems and differences among them. The results showed that the Tübingen cup was the best performing device to measure kinetic energy of the rain, but, because of its design, it is not possible to measure the detached splashed sediment under natural (field) conditions. On the other hand, the funnel device showed a significant relation with rain intensity because it loses little sediment to washing. In addition, the device is easy to use and cheap. Therefore, this device is highly recommended to estimated splash erosion. to the good performance measuring the actual splash erosion, because it loses little sediment by washing. The device is also cheap and easy to install and manage.

Abstract:

ABSTRACT Smartphones, tablets, and other personal electronic devices have become ubiquitous in Americans' daily lives. These devices are used by people throughout the day, including while preparing food. For example, a device may be used to look at recipes and therefore be touched multiple times during food preparation. Previous research has indicated that cell phones can harbor bacteria, including opportunistic human pathogens such as Staphylococcus and Klebsiella spp. This investigation was conducted with data from the 2016 Food Safety Survey (FSS) and from subsequent focus groups to determine the frequency with which consumers use personal electronic devices in the kitchen while preparing food, the types of devices used, and hand washing behaviors after handling these devices. The 2016 FSS is the seventh wave of a repeated cross-sectional survey conducted by the U.S. Food and Drug Administration in collaboration with the U.S. Department of Agriculture. The goal of the FSS is to evaluate U.S. adult consumer attitudes, behaviors, and knowledge about food safety. The FSS included 4,169 adults that were contacted using a dual-frame (land line and cell phone interviews) random-digit-dial sampling process. The personal electronics module was the first of three food safety topics discussed by each of eight consumer focus groups, which were convened in four U.S. cities in fall 2016. Results from the 2016 FSS revealed that of those individuals who use personal electronic devices while cooking, only about one third reported washing hands after touching the device and before continuing cooking. This proportion is significantly lower than that for self-reported hand washing behaviors after touching risky food products such as raw eggs, meat, chicken, or fish. Results from the focus groups highlight the varied usage of these devices during food preparation and the related strategies consumers are using to incorporate personal electric devices into their cooking routines.

Abstract:

The design solution for the use of hardware method in the formation of water treatment system in the technological processes of metalliferous sands processing by mobile beneficiation complexes is considered. The purpose of the study is to develop a system for separation of process water from the flows of hydro-mixture from washing sands at alluvial deposits. From the comparative analysis and evaluation of known systems of recycled technological water preparation in the mining and processing industry the thin-layer separation effect is adopted. The object of the research is a thin-layer device, the novelty of which is protected by patents of the Russian Federation. The layout variant of this device made in the form of a module on the principles of nodes unification taking into account peculiarities of equipment operation in extreme conditions without additional expenditures of energy, with formation of technological flexibility and transportability at the change of washing places is shown. Industrial researches of thin-layer devices at the objects of alluvial metal-mining in water-treatment systems for sand washing have shown high dividing ability of the formed hydrosand mixture with possible return up to 80-90 % of technological water into turnover. A qualitative and quantitative assessment of the proposed hardware version of building closed circuits with the formation of local contours of water flows is given. Such a hardware design of the separation process of epheline tailings from sand washing out of contact with the natural environment increases the environmental safety of the surrounding area in mining areas and refers to the resource-saving technology

Abstract:

Microelectromechanical system (MEMS)-based piezoelectric energy harvesting (PEH) devices can convert the mechanical vibrations of their surrounding environment into electrical energy for low-power sensors. This electrical energy is amplified when the operation resonant frequency of the PEH device matches with the vibration frequency of its surrounding environment. We present the electromechanical modeling of two MEMS-based PEH devices to transform the mechanical vibrations of domestic washing machines into electrical energy. These devices have resonant structures with a T shape, which are formed by an array of multilayer beams and a ultraviolet (UV)-resin seismic mass. The first layer is a substrate of polyethylene terephthalate (PET), the second and fourth layers are Al and Pt electrodes, and the third layer is piezoelectric material. Two different types of piezoelectric materials (ZnO and PZT-5A) are considered in the designs of PEH devices. The mechanical behavior of each PEH device is obtained using analytical models based on the Rayleigh–Ritz and Macaulay methods, as well as the Euler–Bernoulli beam theory. In addition, finite element method (FEM) models are developed to predict the electromechanical response of the PEH devices. The results of the mechanical behavior of these devices obtained with the analytical models agree well with those of the FEM models. The PEH devices of ZnO and PZT-5A can generate up to 1.97 and 1.35 µW with voltages of 545.32 and 45.10 mV, and load resistances of 151.12 and 1.5 kΩ, respectively. These PEH devices could supply power to internet of things (IoT) sensors of domestic washing machines.

Abstract:

The faded-on stains of cotton clothes are a common daily phenomenon. The desorption and adsorption of reactive dyes are theoretically responsible for the faded-on stains on cotton clothes in the washing microenvironment, especially when the light color cotton fabrics ( LCFs) are washed together with the cotton fabrics dyed in highly saturated color ( CFSCs). However, the effects of washing parameters on the desorption and adsorption kinetics of reactive dyes and the mitigation of faded-on stains in the washing microenvironment through washing parameter optimization are poorly understood. This study thoroughly discusses the desorption and adsorption behaviors of reactive red 195 in the washing microenvironment from the inhibition of color transfer. Firstly, CFSCs and LCFs were prepared by using reactive red 195 and cotton fabrics. Secondly, the effects of washing parameters, washing temperature, washing liquor ratio, and washing solution pH, on the dye desorption and adsorption rate were studied with the simulated washing device ( SWD), followed by the response surface analysis of washing parameters. Thirdly, the modeling of desorption and adsorption kinetics and velocity were detailed. Finally, the model of dye desorption and adsorption was validated in a drum washing machine ( DWM). The results are helpful for the design of scientific washing procedures to curb the faded-on stains of cotton clothes effectively.

Abstract:

Currently, the process of washing clothes is a commonly process that carried out in a household. To save human energy and washing time, a washing machine is used. There are a lot of washing machine models on the market, but in general the existing washing machine have standard functions, use electrical energy, quite expensive, and use materials that are less environmentally friendly. Based on these various shortcomings, it is necessary to design an innovative washing machine. The method used in this research is the concept of product design starting from seeing the needs to develop the desired product concept until making a product prototype. The washing machine designed in this study can be used to wash all types of clothes weighing 3 kilograms and is equipped with clothes drying device with a capacity of 20 clothes that rotates during the washing process, so it will speed up the drying process. In addition, the materials used come from secondhand goods, so the price is economic. This washing machine is not designed use electrical energy but kinetic energy, so it is environmentally friendly and can be also used as an exercise tool that can the user's body keep healthy and ergonomic when used.

Abstract:

Reduction of noise generated by devices is an important problem, both in industrial environments where high sound pressure levels may damage hearing, and in households where the sound pressure level is usually moderate, but may cause discomfort and stress. Classically used passive methods often have poor performance for low frequencies. Alternatively, active control can be used to improve noise reduction in this frequency range. In the proposed approach, noise generated by devices may be reduced by controlling vibrations of the casing. The authors previously confirmed the performance of the proposed active control approach using a dedicated noise-canceling casing. Herein, we describe further development and application of the method to an off-the-shelf washing machine. Electrodynamic actuators were installed on four walls of the washing machine. The performance of the control systems was experimentally evaluated during the real spinning phase and the results are reported here.

Abstract:

Today recovery of platinum from used auto catalysts has become a necessity due to great demand for this catalytic metal. There are many methods of recovering platinum from used catalysts on the market, one of them is the original collector metal method using the magneto-hydrodynamic (mhd) pump. This method is based on the continuous flow of the collector metal (lead) in the channel of the device, which can be obtained by using the mhd pump at the device operating temperature of 673 K. Proper selection of process parameters such as power frequency (25–100 Hz), inductor current density (20 A, 40 A, 60 A), gaps between the inductor and the liquid metal channel (2,4,8), flow velocity, secondary voltage (19 V, 40 V, 60 V) ensures proper efficiency of the device. Some parameters were selected on the basis of numerical simulations, others were experimentally verified—the tests were carried out for different washing out times (600 s to 3600 s), and different secondary voltage and inductor supply frequency (25 Hz to 45 Hz). Platinum washing out efficiency of up to 98% was obtained with a relatively short washing out time and low values of secondary voltage and inductor frequency. To improve the efficiency of the process, the thermal efficiency of the device was increased by 8% by insulating the cover of the device. Further modifications to the process include changing the collector metal—preliminary studies show that the addition of lithium increases the extraction of platinum from thin catalytic layers as a result of reduced surface tension of the extraction liquid. The preliminary results of the PbLi alloy spread on platinum coated surface seem to be very promising.

Abstract:

One of the most distinctive features of denim is that the warp yarn is dyed with indigo dye and the weft yarns are not dyed, i.e. white. Although warp yarns dyed with indigo dye are woven with different woven fabric weaves, classical denim fabrics weave are produced with 3/1 Z twill weave. The search for new products in denim has led businesses to produce denim-looking knitted fabrics. Denim-looking knitted garments are subjected to industrial washing at the production phase and repetitive household washing processes in daily life. Repeated washing and drying processes cause changes that can affect user satisfaction in terms of losing the colour of the fabric. Therefore, in this study, the colour values of knitted denim fabrics produced as an alternative to denim fabrics manufactured by traditional methods after various industrial (rinse, enzyme and stone washing) and home washes (5, 10, 20 times) were examined. For this, the CIELab colour system was taken as the basis for colour analysis on a spectrophotometer device. As a result of the washing processes performed on each fabric sample (household washing and rinse, enzyme, stone washing applications), it was observed that there were differences in colour values depending on the fibre type, loop yarn length, fabric construction and washing process.
