In order to reduce the impact of daytime climate fluctuation on the performance of the Trombe wall system (TWS) and enhance its ventilation and cooling effect in summer, an improved phase change material (PCM) TWS was constructed in this study. In this paper, the thermal performance of the PCM TWS was evaluated by comparative experiments in hot and humid area of China in summer. The findings demonstrated that the PCM TWS provided more effective heat insulation than the common envelope and the typical TWS. During the day the PCM cold storage plate released the cooling capacity with a peak heat flow rate of - 25.1w/m2 and it accumulated cold energy with a peak heat flow rate of 20.1w/m2 during the night. The PCM TWS achieves better induced ventilation than the typical TWS, corresponding to a maximum room ventilation rate of 140m3/h (31h−1) and a minimum value of 29m3/h (6 h−1). The PCM TWS can significantly lower the indoor air temperature to a maximum of 2.1 °C compared to the typical TWS and 5 °C compared to the ordinary envelope.

The stable carbon isotope composition of the structural carbonate derived from animal bone hydroxylapatite (δ13CB-HA) could record an animal’s diet. These records provide critical evidence for different paleontological disciplines, e.g., paleodiet analyses, and paleoclimate reconstructions. Compared to those of other body tissues, such as bone collagen or teeth enamel hydroxylapatite, δ13CB-HA values record information on the whole diet of an animal in its last years. δ13CB-HA can be applied to fossil animals of various body sizes. The δ13C analytical instruments available only require that prepared bone samples be approximately 2–5 mg for precise measurement, allowing δ13CB-HA analysis to be feasible on most vertebrate fossils without destructive sampling, especially on small mammals or birds whose teeth are not large enough for sampling or are lost. Moreover, δ13CB-HA can be used from different times or under less than ideal burial environments. For fossils dating back to Devonian or buried in hot and humid regions, dietary information has been completely lost in bone collagen during post-depositional processes but still remained in the δ13CB-HA values because hydroxylapatite is less influenced by diagenetic effects after deposition. In addition, systematic methods such as X-ray diffraction and Fourier transform infrared spectroscopy have been developed to qualitatively or semiquantitatively assess the influence of diagenesis on bone hydroxylapatite to ensure the credibility of the δ13CB-HA values. With the above merits, δ13CB-HA analysis is therefore becoming an increasingly important method in paleodiet-related research. Currently, applications of the δ13CB-HA method on fossil animals are primarily focused on two aspects, namely, paleodietary reconstruction of fossil animals with uncertain diets and paleoenvironmental reconstruction based on the δ13CB-HA values of fossil herbivores. The published researches, combined with our new results from early birds, demonstrate the considerable significance of the δ13CB-HA method in paleontological and paleoenvironmental research. Notably, the δ13CB-HA-based paleodietary analysis of early vertebrates, especially the large number of small birds or mammals discovered in the past decades would be an important work in the near future.

BACKGROUND Persons with an amputation may have an increased heat strain due to reduced surface area. However, there is limited evidence on the thermoregulatory responses in persons with lower-limb amputation (LLA). Although a previous study reported no difference in their rectal temperatures (Tres) in a hot environment, suggesting compensatory sweating of the intact limb, we examined the thermoregulatory responses of such persons in a hot and humid environment. OBJECTIVE To compare the thermoregulatory responses-through changes in Tre, sweat, and oxygen uptake (O2)-between persons with LLA and able-bodied (AB) individuals, in hot and humid environments. STUDY DESIGN A nonrandomized control trial. METHODS Nine AB men (AB group) and nine persons with LLA group performed the arm ergometer exercise at 60% peak power output intensity for 60 min in a hot and humid environment, and they were tested before and after performing. The O2, Tre and skin temperature, and total body sweating, and local sweating during exercise were measured and compared between the groups. RESULTS The changes in O2 and Tre after the endurance exercise did not differ between the groups (ΔTre: AB group, 1.1°C ± 0.5°C; LLA group, 1.2°C ±0.3 °C; P = 0.65), whereas the amount of local sweating of the chest (group effect, P < 0.01 by two-way analysis of variance [group × time], the group effect size was medium, η2 = 0.10) and dehydration rate (AB group, 1.5% ± 0.5%; LLA group, 2.1% ± 0.5%; P = 0.03) were higher in the LLA than in the AB group. CONCLUSIONS We compared the thermoregulatory responses of persons with LLA with those of AB individuals in hot and humid environments. Core body temperatures of persons with LLAs during endurance exercise were not different from those of AB men even in hot and humid environments. We found compensatory increases in the sweat rate of the chest and increased dehydration rate in persons with LLA. More sweat potentially means that athletes with LLA need to drink more fulids.

Reference evapotranspiration (ETo) is a key pointer of atmospheric evaporation demand and has been extensively used to describe the hydrological change. In this study, the reference evapotranspiration over the hot and humid town, Annamalainagar, very near to the east coast in Tamilnadu State, India, have been estimated employing the FAO Penman-Monteith (PM) method and the observed daily weather data during 1977-2016. The objective of the present study is two-fold: (i) To identify the multi-decadal trend of the various measured meteorological parameters namely, mean air temperature (Tmean), vapour pressure deficit (VPD), actual sunshine hours (SSH), net radiation (Rn) and wind speed (WS) at the study location and (ii) To identify the main contributing meteorological parameter for the detected decreasing trend in ETo over the multi-decadal period.

Surgical masks are widely used for the prevention of respiratory infections. However, the risk of heat stroke during intense work or exercise in hot and humid environment is a concern. This study aimed to examine whether wearing a surgical mask increases the risk of heat stroke during mild exercise in such environment. Twelve participants conducted treadmill exercise for 30 min at 6 km/h, with 5% slope, 35°C ambient temperature, and 65% relative humidity, while wearing or not a surgical mask (mask and control trials, respectively). Rectal temperature (Trec), ear canal temperature (Tear), and mean skin temperature (mean Tskin) were assessed. Skin temperature and humidity of the perioral area of the face (Tface and RHface) were also estimated. Thermal sensation and discomfort, sensation of humidity, fatigue, and thirst were rated using the visual analogue scale. Trec, Tear, mean Tskin, and Tface increased during the exercise, without any difference between the two trials. RHface during the exercise was greater in the mask trial. Hot sensation was greater in the mask trial, but no influence on fatigue and thirst was found. These results suggest that wearing a surgical mask does not increase the risk of heat stroke during mild exercise in moist heat.

Perovskite/silicon tandem solar cells are emerging as a high-efficiency and prospectively cost-effective solar technology with great promise for deployment at the utility scale. However, despite the remarkable performance progress reported lately, assuring sufficient device stability-particularly of the perovskite top cell-remains a challenge on the path to practical impact. In this work, we analyze the outdoor performance of encapsulated bifacial perovskite/silicon tandems, by carrying out field-testing in Saudi Arabia. Over a six month experiment, we find that the open circuit voltage retains its initial value, whereas the fill factor degrades, which is found to have two causes. A first degradation mechanism is linked with ion migration in the perovskite and is largely reversible overnight, though it does induce hysteretic behavior over time. A second, irreversible, mechanism is caused by corrosion of the silver metal top contact with the formation of silver iodide. These findings provide directions for the design of new and more stable perovskite/silicon tandems

Coronavirus disease (COVID-19) has emerged as a major global challenge since 2019. With the fast rise in the infected cases and deaths worldwide, many environmental and climate-related myths and fallacies spreaded fast. These fallacies include virus cannot spread in hot and humid conditions, cold weather can inhibit the virus, drinking hot water and sunlight can help cure the COVID-19, ultraviolet (UV) disinfectant lamps and UV rays from sunlight can kill the virus, use of hairdryers and hot showers for virus prevention, etc. Social norms and mindset of the people in the world towards a pandemic are quite similar. The primary purpose of this article is to enlighten the readers regarding these climatological misconceptions and social fallacies, helping spread proper knowledge and manage the outbreak of this deadly pandemic.

Introduction and Aim: The most common practice for marking the radiation field borders in conventional radiotherapy is with marker pens. In the hot and humid environment in India these markings rapidly fade and require remarking. In some cases, they require re-simulation and re-planning. Mehndi has been used in India for ceremonial marking on skin for long. Here we seek to evaluate the same for radiotherapy. Materials and Methods: Eighty-two patients with no history of hyper-sensitivity to mehendi were scheduled to be analyzed on per protocol treatment basis, with 41 in each arm. Subjects were randomized by lottery method till the target number in one of the arms is reached. Since one subject in each arm had not received the per protocol management due to default, two more subjects were included and randomized. The minimum duration of treatment was 5 weeks. Markings were done either with mehndi cones (Arm A) or conventionally used Skin marking pens. They were repeated as per requirements. The number of application and gap between them were recorded. The data was later analyzed with SPSS v23 for frequencies, independent sample T test, including Mann-Whitney test. The analysis was per protocol. Results: No incidence of hypersensitivity to mehendi occurred.The mean and median number of applications was significantly less in the Mehndi arm compared to control arm (median being 2 in mehndi arm compared to 4 in Pen arm). The median gap between applications and each application was also significantly lower in the Mehndi arm (11.5 days vs 7.25 days). There was no significant difference with visualization. The comfort level of the technologists, consultants and patients were better with Mehndi than with pen arm on Likert scale. Conclusion: Mehndi is more durable than the pen marking it is equally visible for health care professionals and more comfortable to patients. The skin tone of our patients did not pose any challenge in visualization during set up either in ambient lighting or with lasers.

[Objective] This study examined seasonal differences in continuous positive airway pressure (CPAP) therapy adherence among patients with obstructive sleep apnea (OSA). [Methods] Patients aged ≥20 years with OSA who had used CPAP devices on the automatic setting for >12 consecutive months (n = 141) were included in this retrospective study from December 2015–2016. The information of CPAP use (pressure, hours of actual use) was extracted from database downloaded from patients’ CPAP devices. Patients were divided into adherent and non-adherent groups using the cutoff point of 70% CPAP use for ≥4 h daily over the 1-year study period. CPAP use data were averaged for each season. [Results] Patients in the adherent group were significantly older than those in the non-adherent group (p < 0.001). In the adherent group, the rate of ≥4 h daily CPAP use was significantly lower, the daily duration of CPAP use was significantly shorter, and the residual apnea–hypopnea index (AHI; events/hour) was significantly higher in summer than in other seasons (all p < 0.001). In the non-adherent group, the duration of daily CPAP use and the AHI differed significantly between winter and summer (p = 0.008 and p < 0.001, respectively). [Conclusions] Seasonal changes were associated with the CPAP adherence of patients with OSA. The study findings suggest that there is possibility of increasing the duration of CPAP use by adjusting the bedroom environment in hot and humid seasons.

Recent studies underline that simple and non-invasive retrofit solutions can recover natural ventilation potential in existing buildings under temperate climate. Nonetheless, the efficiency of these solutions in dense urban contexts under hot and humid climate remains unclear. This paper aims to evaluate the thermal comfort gains caused by natural ventilation when retrofitting an office building in downtown Rio de Janeiro. Computational Fluid Dynamics (CFD) and thermal simulations are carried out on Ansys CFX and Design builder to assess indoor air flow before and after retrofit. The diagnosis of the current scenario indicates that the surrounding buildings block a significant part of the wind flow, and occupants experience only a few hours of thermal comfort during the year, especially on lower floors. To increase indoor air flow, the fixed upper windows were transformed into pivot windows and kept open permanently. This measure increases the annual hours of thermal comfort by 0.5-35%, depending on the floor and the adaptive comfort model. These findings suggest that natural ventilation itself may not be sufficient to ensure occupants' comfort throughout the year under the investigated context.

The greenhouse is vital to protect indoor crops from the harsh hot-humid climate. This study firstly identifies design attributes of greenhouses such as dimension, shapes, orientation, and shading. Secondly, it assesses the impacts of design attributes on the greenhouse daylight performance using VeluxVisualizer. The results showed an increase in the number of skylights caused higher average daylight illuminance in the greenhouse. All the models passed the requirement for plants with small sunlight claim between 7 and 9 hours per day. This study paves the way for energy-efficient buildings with the aid of building simulation to benefit the users.

In Louisiana, most districts restripe their roadways using waterborne paints every other year; this strategy is questionable in relation to efficiency and economy. Previous studies show substantial variability in paint service life throughout the U.S.A., ranging between 0.25 and 6.2 years. Shortcomings in modeling the retroreflectivity of waterborne paints appear to significantly contribute to these variations as several studies predicted these values using degradation curves with a coefficient of determination (R2) as low as 0.1. Therefore, the objective of this study was to develop new cost-effective restriping strategies using 4 in. and 6 in. wide waterborne paints (15 and 25 mils thickness) when applied on asphalt pavements in hot and humid climates. To achieve this objective, National Transportation Product Evaluation Program data were collected and analyzed to evaluate the field performance of waterborne paints commonly used in southern states of the U.S.A. and to develop a decision making model that may be used by transportation agencies to predict when to restripe their roadways. Results indicated that 4 in. wide standard paints exhibited service life up to four years depending on the line color, traffic and initial retroreflectivity, while 4 in. wide high build paints had a service life of at least three years. Based on a life-cycle cost analysis, it was concluded that Louisiana Department of Transportation and Development could restripe its district roads every three years instead of the current two-year period using the same product (4 in. or 6 in. wide) saving about $20 million or $2 million, respectively, every year when restriping a 5,000-mi network.

The skylight on the roof of an atrium can be popular for commercial malls to illuminate the core area of the building. However, the solar radiation and its heat can get into the building together with the daylight, causing excessive cooling load. This paper studies the daylighting and energy performances of skylight coverage area for the air-conditioned atriums in the hot and humid regions. The energy performance with different atrium heights, glass types and the coverage ratios of the skylight are studied. The daylight performance was simulated by the ray-tracing Radiance and was transferred into EnergyPlus for energy evaluations. The finding suggested that, for hot and humid climates, the skylight coverage ratio should be controlled carefully to prevent the excessive solar heat gain. When the on/off lighting control is applied, the total energy consumption of the single-floor cases (or of the top floor for the multi-floor cases) leveled off when the coverage ratio of the skylight reached 9%. Thus, the skylight is favorable to the energy saving of the low-rise or single-floor commercial buildings only under the current assumptions, as the ground of the atrium cannot be well illuminated while the excessive solar radiation gets into the building. The skylight should be shaded in cooling seasons to prevent the excessive solar heat gains.

A new type of flax fiber-reinforced bio-sourced thermoset composites is investigated to explore their usage in hot and humid conditions and is compared with flax fiber reinforced epoxy composites. Hygrothermal aging of composites is carried out for 40 days at 50 °C and 90%RH. The influence of moisture uptake of composites during aging is evaluated in terms of physical parameters (i.e., swelling and weight gain) and mechanical properties. The deterioration of the mechanical properties during aging is mainly attributed to the presence of flax fibers, especially the fiber-matrix interface. The evolution of flexural properties induced by aging is similar for both synthetic epoxy composites and bio-based benzoxazine composites and is described using an analytical model. The mechanical test results show that after 40 days of aging, flax/benzoxazine composites lose about 20% of their flexural properties whereas flax/epoxy composites lose about 32% of properties. The recovery of flexural properties after drying is higher for flax/benzoxazine composites than for flax/epoxy composites, which demonstrates the potential of this bio-sourced thermoset composite material.

The field experiments were conducted at Student’s Instruction Form, ANDUA&T, Kumarganj Ayodhya. The climate is hot and humid summer and cold winters, during the rabi crop season in the year 2017-18.

Under tropical climate, broiler production is encumbered by several constraints which make it difficult for them to attain their genetic potential. The scarcity and high price of poultry feed and veterinary services and the harsh environmental conditions with respect to thermal stress are some of the challenges that hinder optimal growth of the birds. Limited availability of feedstuffs, including crucial feed ingredients like maize and oil seedcakes, is an important challenge to the sector, since feed still represents a major cost of producing broiler chickens. Additionally, the problem of climate change, which has become a global concern, is the main problem in broiler production under hot and humid climate. Under high ambient temperature, feed intake decreases, carbohydrates metabolism and protein synthesis efficiency are disturbed. Lipid utilization is lower and glucose or insulin homeostasis is altered while fat deposition and oxidative stress increases. Several strategies are used to ameliorate the effect of heat stress in poultry. The objective of this review was to summarize the challenge in broiler production under hot and humid climate and different approaches to fight heat stress in poultry., Broiler farmers are confronted with crucial problems under tropical climate. The most important is harsh environmental conditions. Heat stress which lead to oxidative stress impairs glucose metabolism, protein efficiency and decreases production performances of broilers.

Nowadays, the achievement of a good sporting performance depends on a good development of physical capacities from a young age while respecting the different stages of growth. In spite of this, some football coaches and trainers have no mastery of the principles of training. They subject children to physical effort that does not correspond to the child's developmental stages. In order to evaluate the respiratory function and maximum oxygen consumption of children trained in football, series of test matches were organised by age group under a temperature of 38°C and a humidity of 60%. The results of the study show an increase in maximum oxygen consumption according to age with extremes of 36, 54 ml/min/kg and 55, 99 ml/min/kg. The classification of the values of V ̇O2max according to the spirometry values shows a representativeness of 13-14 year old children in the class of low spirometry values (CV, FEV1 and DEP) and a strong representativeness of 16-17 year old children in the class of high spirometry values (CV, FEV1 and DEP). A correlation exists between maximum oxygen consumption, spirometry equations and anthropometric parameters during the growth of children playing football.

One hundred milliliters of milk produced in the first 150 days of lactation of 24. Bunaji (White Fulani) cattle in Ibadan contained an average of 703, 659, 44, 557, 146, 21, 27 and 54 mg total nitrogen (TN), protein nitrogen (PN), non-protein nitrogen (NPN), casein nitrogen (CN), non-casein nitrogen NCN), proteoses-peptone nitrogen (PPN), lactoglobulin nitrogen (LGN) and lactalbumin nitrogen (LAN) respectively. CN, NCN, PN, NPN, PPN, LGN and LAN accounted for 79.2, 20.8, 93.7, 63, 3.1, 3.9 and 7.6% of TN respectively. CN constituted 833% of PN while one-third of NCN consisted of P PN and LGN. The most abundant component of NCN was LAN which occurred twice as high as LGN. The influence of stage of lactation was significant (P < 0.05) on TN, more remarkable on PN and CN but not significant (P >005) on NCN, NPN, PPN, LGN and LAN, Only TN and CN were significantly (P < 0.05) correlated (r 0.989). The positive or negative relationships between the other nitrogen fractions were trivial.

The use of living walls has been increasing around the world due to their several benefits. However, studies of suitable plant species for living walls, particularly in extreme climates, are quite limited. This study examines the performance of 12 plant species used in two living wall systems: a felt-pocket and a planter in a tropical climate in Thailand. All plants were monitored across wet and cold seasons for plant height, visual quality, thermal performance, and carbon sequestration. The findings show variations in plant performances across the 12 plant species. Increases in plant growth were observed for all plants except for herbaceous and succulent plants, which were less tolerant to wet conditions. Smaller plant increments resulted in poorer thermal properties and less potential for carbon sequestration. The planter system had a higher amount of carbon contents than the felt-pocket system due to its higher plant density. Over 6 months, living wall systems sequestered carbon, with averages of 48.2 g C·m−2 for the felt-pocket system and 166.7 g C·m−2 for the planter system.

The present paper investigates the performance of a conventional single slope passive solar still (CSS) under the influence of a paraffin based phase change material (PCM) and a nano-PCM (n-PCM) in terms of the fresh water production per day. To achieve this objective, three solar stills with the same dimensions were designed and fabricated. Among them, one still was left without any modification (CSS), another one was incorporated with paraffin as PCM (PCMSS), and third one was assimilated with an n-PCM (NPCMSS). Previously, the n-PCM was prepared by adding 0.5% mass of silica nanoparticles in paraffin. The experiments had steered on a hot and humid weather at Coimbatore, India during the month of April 2020. The results evidenced that the incorporation of PCM and n-PCM improved the fresh water production by 51.22% and 67.07%, respectively.

The study was carried out to evaluate the feed consumption and performance of five coloured types of chickens reared under intensive system in the hot and humid climate conditions. The growth parameters like body weight, feed consumption, and feed conversion ratio of the coloured birds like Aseel, Dahlem Red, Kaveri, Kadaknath and Rhode Island Red were studied in the intensive conditions. Carcass characteristics, incidence of mortality and cost of production of different types of coloured chicken were measured. Kaveri showed the highest body weight gain and Kadaknath the lowest (P≤0.05) among the five types and the sequence found was: Kaveri>Dahlem Red>RIR>Assel and Kadaknath. Feed conversion ratio followed the order: Kadaknath/RIR/Dahlem Red> Aseel>Kaveri, the differences being significant (P≤0.05). The mortality rate was highest for Rhode Island Red (20%) followed by Dahlem Red (10%), Kaveri/Kadaknath (8%) and Aseel (2%). The dressing percentage was higher in Rhode Island Red, Kaveri and Dalhem Red than Assel and Kadaknath. Some other carcass parameters like back, thigh and drum stick yield percentage also differed significantly among the types of chicken. The cost of production per kg live weight or per kg dressed weight was the lowest for Kaveri and highest for Kadaknath. From the above experiment it was concluded that Kaveri excelled the other colored chicken type in respect to the body weight gain, feed efficiency followed by RIR, Dahlem Red and Aseel.

Citrus canker presents major challenges in citrus production worldwide. The disease spreads and develops rapidly under conducive environmental conditions, and Louisiana’s hot and humid weather provides highly favorable conditions for citrus canker development in both commercial and backyard citrus production. Despite being considered eradicated in late 1940s, citrus canker was reconfirmed in Louisiana in 2013. Citrus is the most popular fruit tree grown commercially and in backyards in Louisiana, and satsumas dominate with 63% of total citrus acreage. The results from an annual citrus cooperative agricultural pest survey from 2014 to 2016 revealed that satsumas are highly tolerant to citrus canker with only 2.5% disease incidence, but the survey lacked information on the types of satsuma cultivar. The main objective of this study was to screen commercially available satsuma cultivars including Brown’s Select, Louisiana Early, Miho, Owari, and St. Ann for their susceptibility to citrus canker under natural field disease inoculum conditions with a goal to provide citrus growers with alternate disease management tactics. The results showed that there were significant differences in disease severity (average number of lesions per leaf) among the satsuma cultivars. Of the five satsuma cultivars, Brown’s Select and Miho consistently showed less disease severity with delayed incidence. Additionally, both Brown’s Select and Miho exhibited significantly smaller lesion size, which could lower canker inoculum production for secondary infections. This work provides Louisiana growers with scientific field-based data to make sound decisions in selecting less-susceptible satsuma cultivars for future plantings to mitigate disease spread and development in the state.

Concerns about product stability may limit or prevent access to treatment for patients and may limit their ability to live a close-to-normal life. This study evaluated the effect of hot and humid storage conditions on the long-term stability of the recombinant FVIII products, turoctocog alfa and turoctocog alfa pegol.Methods: Turoctocog alfa samples were assessed for stability at 30°C for 9 months or 40°C for 3 months following storage at 5°C for 21 or 27 months, respectively, while turoctocog alfa pegol samples were assessed at 30°C for 12 months or 40°C for 3 months following storage at 5°C for 18 or 27 months, respectively. In addition, turoctocog alfa and turoctocog alfa pegol dry powders were evaluated for stability at 5°C/ambient humidity (AH) for 30 months, 30°C/75% relative humidity (RH) for 12 months and 40°C/75% RH for 6 months. Both studies utilized a range of product strengths. Key stability assessments included oxidized forms, potency, water content and high molecular weight protein (HMWP).Results: Both turoctocog alfa and turoctocog alfa pegol remained stable following storage at 40°C/75% RH for 3 months, and at single temperatures (5°C/AH, 30 and 40°C/75% RH), without any major increase in HMWP or any impairment of potency or water content.Conclusion: Turoctocog alfa and turoctocog alfa pegol offer stability at 40°C for up to 3 months without jeopardizing the quality of each product. These stability characteristics may offer patients flexibility with product storage and daily use.Keywords: factor VIII, hemophilia A, storage flexibility, temperature stability, turoctocog alfa, turoctocog alfa pegol

Air conditioning systems that utilize solar energy are generally cost-effective when used to provide cooling requirements in commercial, home, and industrial buildings as well. The utilization of solar energy is the least compared to the various form of renewable energy sources. Air conditioning is required in hot and humid climates such as India to maintain thermal comfort in closed rooms. The widespread use of these air conditioning systems will significantly increase electricity demand during the summer. The country is facing major power supply problems due to power shortages. In this study, solar collector designed as per Delhi’s geological coordinates and 4 different times of hours i.e., 12, 14, 16 & 18 on 11 July of a year. From the numerical results, the flat plate collector in 12, 14, 16, & 18 h in a day on 11 June in Delhi, at 12 times of hours when the sun is at peak. From the temperature profiles, it is evident that the temperature on the absorber is very high and also efficiency. It was concluded that the efficiency and temperature of absorber at different 4 points of times in a day which helpful for researchers to design solar-powered air conditioner using a flat plate collector.

The study was carried out to compare the growth performance, gut microbiota, incidence of footpad dermatitis (FPD), leg weakness, physiological, and immunological responses in broilers kept in cage (CS) and floor pen (FS) rearing systems under a tropical environment. One-day-old male Cobb 500 chicks were allocated to either three-tiered wire-floored battery cages or floor pens with wood shavings. The body weight on day 42 and feed intake from days 1 to 42 of caged chickens were lower than those of chickens reared in floor pens. However, the caged chickens had significantly better overall (days 1–42) feed conversion ratios than those on floor pens. The FS system was detrimental to the incidence of FPD. The FS birds showed higher and lower caecal counts of Escherichia coli and Salmonellae, respectively than the CS birds. The FS birds had longer durations of latency-to-lie than their caged counterparts, which suggested that the former had a lower incidence of leg weakness. Higher serum basal concentrations of corticosterone, ovotransferrin and ceruloplasmin were noted in the FS chickens compared to the CS group. Antibody titre against Newcastle disease vaccinations was not affected by the rearing system. In conclusion, the cage rearing system appeared to benefit performance, the incidence of FPD, physiological response, fear reactions, and intestinal population of E. coli in broiler chickens under the hot and humid tropical conditions. However, raising broilers on floor pens improves body weight and leg strength, and reduces the caecal Salmonellae population compared to caged broilers.HIGHLIGHTS Caged broilers have better feed efficiency and lower caecal Escherichia coli population and incidence of food-pad dermatitis than those on floor pens. Raising broilers on floor pens improves body weight and leg strength, and reduces the caecal Salmonellae population compared to caged broilers. Broilers on floor pens are more physiologically distressed than their caged counterparts.

The pineapple (Ananas comosus) is one of the most important fruit crop of NEH Region of India. Marbling disease is caused by the acetic acid bacteria Acetobacter peroxydans Visser't Hooft and Erwinia herbicola var. ananas (Serrano) Dye. However, sporadically levels occur only in the lowland tropics and epidemic also occurring of the hot and humid. Infection by marbling bacteria occurs through the open flower. The pineapple fruit purchased from local market of Siang regions of Arunachal Pradesh. Marbling of pineapple is an asymptomatic disease in the field and is evidenced with a brownish coloration when the infected fruit is use to eat and processed. Although, maximum disease incidence (32.4%) recorded from East Siang in the month of August, the purpose of this record of marbling disease is aware to pineapple growers because there is no cost effective disease management method to cultivation of pineapple in Siang regions.

In order to improve the design effect of venues, this paper establishes the evaluation model of indoor thermal comfort for the humid and hot subtropical areas, which provides theoretical reference for venue design. This paper investigates the thermal sensation of basketball players by questionnaire, analyzes the relation-ship between thermal sensation vote and standard effective temperature, predicted mean vote, and wet bulb globe temperature, and develops an index called predicted thermal sensation by using the least square method. The relationship between outdoor air temperature and indoor working temperature under neutral conditions is obtained by measuring data. The results show that the correlation between thermal sensation vote and air temperature is the strongest, R2 is 0.753, while the relationship between thermal sensation vote and air speed is weak, R2 is 0.012. Thermal sensation vote and set, predicted mean vote and wet bulb globe temperature are not suitable for athletes in the field environment.

Os nematoides do gênero Rhabditis são responsáveis por causar a otite parasitária em bovinos leiteiros da raça Gir. Esta afecção parasitária tem sido relatada em vários países de clima quente e úmido. No Brasil, a rhabditiose tem sido descrita em diversas regiões, sendo responsável pela queda na produção de leite nos rebanhos afetados. Ao melhor do nosso conhecimento literário, a otite parasitária gera danos diretos na economia e sanidade animal, contudo, exististe uma certa discrepância no controle e terapêutica utilizados. O objetivo dessa revisão foi proporcionar a comunidade científica, técnicos e aos produtores rurais uma atualização do conhecimento da problemática da otite parasitária no Brasil e no mundo. O controle parasitário do Rhabditis spp., bem como a sua terapêutica ainda são considerados ineficazes, visto que as recidivas são comuns. Dessa forma, a problemática da otite parasitária no Brasil ainda carece de novos estudos, mas alguns protocolos alternativos experimentais recentes apontam sinergicamente para um “horizonte” mais produtivo no controle desta parasitose.
