Portable neonatus incubator based on global positioning system

<p>The role of baby incubator is crucial in assisting premature babies to adjust to their new surroundings. However, the current baby incubator causes challenges when used for emergency first aid. The challenge is often because of its cumbersome size, which makes transportation to referral hospitals difficult. To address this issue, portable neonate incubator based on the global positioning system (GPS) was developed. The results of implementation testing showed that the incubator system effectively monitored longitude and latitude coordinates, as well as the temperature and humidity of the incubator room, and the body temperature of neonates. Weighing approximately 5.8 kg, this incubator was versatile, compatible with both AC and DC voltage power sources, and came equipped with a carrying bag for easy transportation by midwives or medical personnel. Consequently, this development marked an innovative advancement in neonate incubator medical equipment, facilitating the swift tracking of the neonate incubator's coordinate position in case of unexpected events on the way to the hospital.</p>

Thermal performance assessment of traditional Japanese wooden houses with short-term measurements: Machine learning approaches

Traditional Japanese wooden houses are sustainable and vernacular in nature; however, energy consumption owing to poor insulation is inevitable in the winter. These wooden houses in Japan are an integral part of historical landscapes and are protected from the potential risks of retrofitting. To continue using these houses without bearing additional energy burdens, it is necessary to better understand their actual thermal performance. Therefore, this study proposes a combined approach to assess the thermal performance of traditional Japanese-style rooms using in-situ thermal measurements and machine learning predictive methods. The in-situ thermal measurements evaluated the actual thermal environment of traditional Japanese-style rooms with and without air conditioners (AC) during winter. Similarly, two machine learning models, support vector regression (SVR) and random forest regression (RFR) were developed to predict the indoor temperature based on the external factors and their adjacent rooms temperature. The result revealed strong thermal interaction between adjacent rooms, likely driven by heat transfer dynamic. To further investigate these interactions, thermal images of each room were analyzed after the AC was in use. The result revealed the presence of hot and cold spot within the gap of sliding fusuma (thick paper made door) and ranma (transom or indoor ventilation), indicating significant heat transfer between the AC and non-AC rooms. Consequently, the prediction model for the AC room temperature was notably influenced by the thermal conditions of adjacent non-AC room. Thus, this study proposes a simple yet reliable approach that enables resident to prioritize thermal improvements for efficient and cost-effective renovations.

Numerical study using the finite volume method on the thermal and energy performance of a regulated underfloor heating system incorporating PCM in a ventilated room

A physical model is performed to assess the thermal and energetic advantages of using PCM in controlling and regulating the indoor temperature of a ventilated room with an underfloor heating system incorporating a PCM. The heating source is regulated to keep the cavity air temperature in a small interval assuring a certain level of comfort without wasting too much energy. By contrasting our numerical results with numerical data from the literature, the suggested model was validated. Physical processes are solved numerically using computational fluid dynamics by a detailed 2D transient simulation integrating real climatic data of Agadir, Tangier and Casablanca. The simulations carried out justified the suitability of using the PCM with Agadir and Casablanca climate types by a saving of heating power reaching 18.80 % and 17.33 %, respectively.

Method for evaluating of the convective heat transfer of window for the non-uniform radiator heated environment

Understanding heat transfer mechanism of window is crucial to decreasing carbon emission and energy consumption. Distribution of indoor temperature in convective-heating room is uneven and determination of reference temperature in calculating convective heat transfer is still challenging. In addition, near-surface airflow is closely related to convective heat transfer due to the interaction of turbulent eddies and the surface of window. Theoretical and technical attempts on this issue are still insufficient. In this study, experimental measurements were conducted in a radiator heating chamber. Through comparing calculated convective heat transfer of window and actual values, the determinations of reference air temperature and surface temperature of window were suggested. Measurement results and root-mean-square error (RMSE) from different measurement schemes showed the utilization of the air temperature near the thermal boundary layer of window yielded better calculation results. In addition, it was found that center-point surface temperature of window was suggested in the experimental analysis. Through non-linear fitting, a simplified correlation, h=0.146ΔT1.630Vm2.261, was proposed for the convective heat transfer of window. Proposed correlation quantitatively related maximum air velocity near window and convective heat transfer of window. Findings in this study are conductive to further understanding the heat transfer mechanism of window and providing reference for evaluating heating loads of buildings. As one basic research, this study provides theoretical support for evaluating heating loads and multifaceted perspective on building energy efficiency and carbon reduction.

Experimental and numerical investigation of the effects of passive radiative cooling-based cool roof on building energy consumption

Passive radiative cooling is an energy-efficient method that reduces indoor temperature and cooling load in buildings, thus contributing to significant energy savings. This study investigates the thermal performance of the passive radiative cooling-based cool roof (PRC-CR) based on experimental and numerical analysis in terms of indoor air temperature and space cooling load indicators. Two experiment rooms constructed from concrete are developed with an indoor air temperature control system. One is the PRC-CR room with the roof covered by a passive radiative cooling metamaterial and the other is the reference room with a concrete roof. Long-term testing results in Hefei show that the indoor air temperature of the PRC-CR room is 5.5 °C lower in maximal and 1.8 °C lower on average than that of the reference room in summer when the indoor air temperature control system is off. Besides, when the indoor air temperature control system is switched on, the PRC-CR room achieves a 29.1% reduction in daily cooling load in summer and a 4.1% increase in daily heating load in winter, which suggests that passive radiative cooling can indeed save energy in cooling season (i.e., hot season) but cause overcooling in heating season (i.e., cold season). In addition, a simulation building model is developed to further investigate the effect of the PRC-CR on the energy consumption of buildings in different locations. The predicted results show that PRC-CR reduces the total load of buildings in cooling load prevailing regions (e.g., tropical zones, subtropical zones, and the vast majority of warm temperate zones), while increasing the total load of buildings in heating load dominant regions (e.g., most middle temperate zones, cold temperate zones, and plateau climate zones). In summary, this work demonstrates both the positive and negative effects of PRC-CR, providing valuable insights into PRC-CR applications.

Preventing Hypothermia in Newborns With Congenital Anomalies in the Delivery Room.

Thermoregulation interventions in the delivery room have historically focused on preterm infants and studies often exclude term infants or those infants with known congenital anomalies. The purpose of this quality improvement project was to reduce the rate of admission hypothermia in neonates of all gestational ages born with congenital anomalies and admitted to the intensive care unit (ICU). Utilizing the Institute for Healthcare Improvement model for improvement, implementation of plan, do study, act cycles focused on standardizing temperatures of the delivery room and resuscitation bed, recommendations for temperature monitoring, trialing polyethylene lined hats, and implementing a delivery room thermoregulation checklist. Overall, the mean rate of neonates admitted to the ICU hypothermic (<36.5°C) decreased from 27% to 9% over an 8-month period. The interventions significantly reduced the number of neonates admitted to the ICU with hypothermia. Implementation of thermoregulation bundles should apply to all neonates with congenital anomalies to decrease risks associated with hypothermia.

Influence of Human Activity on Radon Concentration, Indoor Air Quality, and Thermal Comfort in Small Office Spaces.

This article focuses on the influence of occupants on the concentration of contaminants (radon Rn-222 and CO2) as well as the thermal comfort parameters. A series of sensors were placed to measure the concentration of the contaminants, temperature, and relative humidity in the test room at the Institute of Nuclear Physics PAN in Krakow (IFJ PAN), Poland. The test room is an office that is typical of the offices used in the facility. The occupants that used the space kept a detailed diary of their entry, exit, and number of people entering. The results showed that the accumulation of contaminants in such spaces may be severe and risks the health and safety of occupants. The accumulation of CO2 was extremely noticeable and did not diminish to the background level between the re-entry of the occupants to the office. The same was consistent for the radon concentration. The study shows how ventilation methods and small changes in occupant work strategy may influence the contaminant concentration within a test zone.

EVALUATION OF THE USE OF RADIATIVE COOLING TECHNOLOGY TO SUPPORT THE AIR CONDITIONING SYSTEM OF A DATA CENTRE

Data centre space cooling systems consume a lot of energy and will increase over the years. Therefore, it is necessary to propose new refrigeration strategies. Radiative cooling (RC) production is a renewable alternative solution with a promising future. In this work, the energy modelling of the air conditioning system of a data centre coupled to a RC emitter is carried out to explore the benefits of this technology. The system consists of a water chiller connected to a cooling coil through which air is circulated for distribution in the data centre room. The simulations were carried out for a typical summer week in Barcelona. The RC production was carried out during the night, and this power was used during the day and was implemented directly in the energy balance of the data centre room, considering emission surfaces of 80 and 60% of the total building roof, reducing the water chiller energy consumption by 13 and 10% respectively. In the transient behaviour of the temperature in the data centre room, when the RC was used to reduce the peak cooling load, a reduction of the temperatures was observed approaching to the design setpoint, therefore, the IT equipment was not affected.

Effects of Hatching Eggs Storage at Room Temperature on Hatching Performance and Day Old Chick Quality of Arab Chickens

This study evaluated the effect of hatching egg storage at room temperature on hatching performance and day old chick quality of Arab chickens. Two hundreds hatching eggs were obtained at the same day from 55-weeks-old Arab chicken flocks. Hatching eggs were then randomly distributed into four treatments, including 1 day storage (1DS), 4 days storage (4DS), 7 days storage (7DS), and 10 days storage (10DS). Each of those treatment using five replicates and each of replicate consisted of 10 hatching eggs. Temperature and relative humidity in the storage room were 27.9 ± 0.55 °C and 55.4 ± 4.84%, respectively. At the end of each storage duration, hatching eggs were incubated at temperature and relative humidity of 37.8 ± 0.08 °C and 58.94 ± 5.66%, respectively, for 516 hours. Result showed that egg storage duration for up to 10 days did not affect (P &gt; 0.05) fertility. However, 4DS treatment had a higher (P &lt; 0.05) hatchability of set eggs and hatchability of fertile eggs. Embryonic mortality was also lower (P &lt; 0.05) in 4DS than the other treatments. Egg storage duration had no effect (P &gt; 0.05) on chick length, hatch yield, and Pasgar score. Whereas, chick weight in 1DS and D4S was higher (P &lt; 0.05) than 7DS and 10DS. Furthermore, saleable chicks in 4DS also higher (P &lt; 0.05) than the other treatments. It could be concluded that hatching egg storage at room temperature for 4 days provides optimum hatching performance and day old chick quality of Arab chickens.

The influence of air movement in providing thermal comfort in naturally ventilated old Mosque Gunong Kleng, West Aceh, Indonesia

Abstract Mosques were created to fulfill the needs of Muslims in prayer, therefore thermal comfort is critical to consider so that the congregation is comfortable and can focus and feel at home while praying. The typology of ancient mosques reflects the community’s traditions and culture, as well as local knowledge values. Natural ventilation, which acts as a natural air exchange mechanism, is one facet of thermal comfort. The Gunong Kleng Mosque, founded in 1927, is one of West Aceh Regency’s ancient mosques. However, design adjustments have been made, such as the installation of wooden boards to on terraced roof. The air flow from the building’s roof is blocked, resulting in inefficient air exchange. The goal of this study is to determine thermal performance and the effect of air movement on thermal comfort at the Old Gunong Kleng Mosque. This study employed a quantitative approach using field measurements of air temperature, relative humidity, and air velocity. An anemometer and a USB data logger were utilized to collect data. Field measurements revealed that ET comfort in the mosque was 78% too hot, 16% warm comfortable, and 6% for optimal comfort. Ansys Fluet simulation with two types of situations was used to forecast air speed, demonstrating that changes in the design of the stepped roof had a significant impact on the air speed within the mosque. When opposed to an open roof, a closed roof slightly lowered the ambient temperature in the prayer room.

Influence of window and door opening on office room environment and human thermal sensation during different seasons in moderate climate

Natural ventilation is commonly used in buildings because it does not require energy, and its various strategies, for example ventilation through an open window, can improve the indoor environment quality, including the thermal comfort of users. This study aimed to determine accurate environmental parameters typical for naturally ventilated rooms for three seasons: summer, autumn and winter, and to assess the occupants' thermal sensation in the mentioned conditions. Based on the measurements, the spatial distribution and time variability of air temperature and air speed in an office room with a stack natural ventilation system were assessed. The resulting data on the indoor environment parameters at different seasons and with various door and window opening configurations were used as an input to simulate human thermal sensation. Three models were used for simulation: predicted mean vote (PMV), the thermal sensation (TS) model developed by Zhang et al., and the advanced dynamic thermal sensation (DTS) model by Fiala et al., which allowed the demonstration of differences in the thermal comfort assessment depending on the method. Measurements have shown that opening the window with the door closed has a negligible impact on the parameters indoor environment parameters in summer; opening the door (cross-ventilation) changes this situation. The effect increased during autumn and winter, which affects users' thermal sensations. The assessment based on the most popular PMV model differed from the indications of advanced DTS and TS models showing significant discrepancies, which may lead to a misinterpretation of thermal comfort for individuals in the room.

IMPLEMENTATION OF COLD CHAIN SYSTEM IN PEELED DEVEINED TAIL-ON VANNAMEI SHRIMP (Litopenaeus vannamei) PRODUCTS

Vannamei (Litopenaeus vannamei) Peeled Deveined Tail-On (PDTO) shrimp is frozen shrimp product consumers highly preferred. However, shrimp products are easily perishable that require a proper cold chain system to preserve their quality, shelf life, and nutritional value. This study investigated the cold chain implementation of PDTO shrimp processing in the fishery industry. The temperature of shrimp products, water, and rooms was monitored during processing. Results showed that the shrimp temperature measured in each process was below 5°C. However, abusive temperatures were detected in water used in the peeling and deveining step and soaking process, while water and shrimp temperatures altered each other. Moreover, room temperatures were recorded under 20°C, conforming to Ministry of Marine and Fisheries regulations. Air Blast Freezer and cold storage temperatures revealed that ABF and CS could not meet the company’s temperature standards. These findings may help shrimp companies monitor steps indicating to have temperature abuse attentively.

ВЛИЯНИЕ УСЛОВИЙ ХРАНЕНИЯ АВТОБУСОВ В КРЫТЫХ ОТАПЛИВАЕМЫХ СТОЯНКАХ НА ИНТЕНСИВНОСТЬ КОРРОЗИОННОГО ИЗНАШИВАНИЯ КУЗОВОВ

The efficiency of the rolling stock of road transport is determined by both the efficiency of organizing transport work and the cost of ensuring the operability of vehicles. One of the current problems with the operation of buses is the corrosive destruction of their bearing structure, which leads to both a reduction in the operating time of vehicles and an increase in the operating costs associated with the overhaul of bodies. During the work, it was revealed that the main reasons for the intensive corrosion destruction of bus bodies are insufficient corrosion resistance of metals that are used in the manufacture of the body frame. The main places of occurrence of body corrosion foci are: wheel arches; rear and lower parts of the bus, which are more affected by adverse road conditions; upper and lower parts of window openings in case of seal leakage. Studies were conducted on the temperature and relative humidity of the indoor heated bus parking area in winter. Based on the results of the study, dependencies were obtained: air temperature in the indoor parking room from ambient temperature, relative air humidity in the indoor parking room from relative ambient air humidity, relative air humidity in the indoor parking room and ambient temperature. The nature of air exchange between the parking room and the environment has been established. According to the results of the study, factors contributing to the intensive corrosive destruction of bus bodies were established.

An innovative double-jet design as an air flow barrier to isolate temperature and humidity in a low-temperature storage room

This study used an innovative double-jet design to isolate the temperature and humidity of a lower temperature storage room (-15 °C) from an adjoining higher temperature room (5 °C). This device can reduce the chance of forming a hazardous area in the working environment. Several axial fans are installed on the top of the flow isolation device (FID) to provide an air flow barrier. Those fans blow the air that can induce the Coanda effects outside of the FID. A blockage body is designed and installed in the downstream area on a perforated plate that can divide the flow into two symmetric separated jets. Computational Fluid Dynamics (CFD) is used to simulate the flow pattern with two different practical air velocities, 5 and 5.6 m/s. The results show that the case where the FID is installed in both rooms exhibits the highest isolation efficiency, up to approximately 94% for RH and 93% for temperature. The findings of flow analysis demonstrate that significant amounts of energy can potentially be saved. The practical implications of these findings could be in food and pharmaceuticals industries.

ИССЛЕДОВАНИЕ ХИМИЧЕСКОГО СОСТАВА НЕКОТОРЫХ ПРЕДСТАВИТЕЛЕЙ РОДА TANACETUM L.

The purpose of the study is to study the biochemical parameters of three species of the genus Tanacetum: T. balsamita L. (balsamite), T. balsamitoides Sch.Bip. (P. balsamonosa) and T. vulgare L. (P. vulgare). For the study, we used the raw materials of tansy produced by OJSC Krasnogorskleksredstva, a wild-growing type of tansy harvested in the Ufa District of Bashkiria, and we also used the raw materials of balsam tansy and balsam-like tansy, grown in the botanical garden-institute (Ufa). For chemical analysis, plants were harvested at the beginning of flowering, cutting off shoots at a level of 10–15 cm from the ground. The raw materials were dried using the air-shade method under canopies in ventilated rooms, laid out in a thin layer and stirred periodically. The raw materials were packaged and stored in accordance with the requirements of regulatory documentation (OFS.1.1.0019.15) at room temperature in a dry room, not infested with pests, with good ventilation, without direct sunlight. Commodity analysis of raw materials was carried out by generally accepted pharmacopoeial methods according to the following indicators: moisture, total ash and ash insoluble in hydrochloric acid. Qualitative detection of biological active substances was carried out using qualitative reactions and chromatographic research methods. Quantitative determination of ascorbic acid (FS.2.5.01.06.18), tannins (OFS 1.5.3.0008.18) and organic acids (FS.38) in tansy flowers was carried out by titrimetric methods, determination of essential oil content by steam distillation (OFS.1.5.3.0010.15). The commodity indicators of the raw materials of the studied tansy samples: moisture, total ash and ash insoluble in a 10 % hydrochloric acid solution do not exceed the content standards specified in the pharmacopoeial monograph. The chemical composition of the studied tansy species contains valuable biologically active substances, among them essential oils, tannins, ascorbic acid, and organic acids, which may allow the use in scientific medicine not only of T. vulgare, but also of T species used so far only in folk medicine balsamita and T. balsamitoides, which successfully passed the introduction test at the South Ural Botanical Garden-Institute of the Federal Research Center of the Russian Academy of Sciences.
