The total influence of external environmental factors by seasons on the spatial structure and motor activity of herd horses of Zabaikalsky breed with year-round grazing was studied. The scientific and economic research was carried out in Trans-Baikal Territory. Grazing of 10 herds of horses (20-27 heads) was carried out on the area of 301.5 km2 at different distances from each other. The distance from the horse-breeding camp was 2300-7900 m. According to the motor activity assessment of horses in the spring and summer seasons during 14 hours of grazing, the average speed was 1.4 and 1.1 km/h, the distance traveled was 16828 and 14827 m. The average air temperature during these periods was 10.4 and 12.2 °С, average air velocity was 4.5 and 2.1 m/s, average relative air humidity was 32.2 and 53.3%. In the autumn period, during 10 hours of grazing, the distance was 13879 ± 195.7 m at a horse speed of 1.2 ± 0.07 km/h, average air temperature of minus 1.1 °C, air speed of 2.3 m/s, and air humidity of 54.4%. In winter, the grazing time was 8 hours, the horses in the experiment covered the distance of 12190 ± 142.3 m at a speed of 1.8 ± 0.03 km/h with an average temperature of minus 24.7 °C, wind speed of 1.5 m/s and relative humidity of 64.7%. In the spring, the horses covered the distance greater than in summer, by 13.5% (p < 0.01), in autumn - by 21.2% (p < 0.001) and in winter - by 38.0% (p < 0.001). The highest nutritional value of pasture herbage was noted in the summer (0.60 feed units/kg of dry weight, 102.3 g of digestible protein/ feed unit). In the spring, the nutritional value of pasture grass was 0.35 feed units/kg of dry weight with 31.5 g of digestible protein.

ABSTRAK Mall saat ini marak menggunakan clerestory sebagai salah satu upaya untuk penerangan alami pada siang hari. Namun, cahaya matahari pada sore hari (barat) akan menghasilkan cahaya matahari yang lebih panas dan silau dibandingkan cahaya matahari pada pagi hari (timur). Oleh karena itu, dengan pemakaian clerestory yang cukup besar pada bangunan, masalah panas tentu tak dapat dihindari. Begitu pula dengan glare yang berasal dari pantulan sinar matahari. Salah satu Mall yang menggunakan clerestory adalah Mall AEON BSD. Pengukuran suhu udara, temperatur efektif, kelembaban udara, kecepatan angin, PMV (Predicted Mean Vote) dan PPD (Predicted Percentage of Dissatisfied) dilaksanakan pada 4 waktu dengan 5 lokasi titik ukur yang memiliki kondisi berbeda untuk membuktikan bahwa clerestory dapat mempengaruhi kenyamanan termal. Disimpulkan bahwa titik 2 yaitu titik yang berdekatan dengan clerestory sisi kanan (ukurannya lebih kecil daripada clerestory sisi kiri) memiliki temperatur efektif dan kelembaban udara yang lebih rendah dari titik lain, dan kecepatan udara (dipengaruhi oleh hembusan AC) lebih tinggi dari titik lain. Responden merasa nyaman saat berada di titik tersebut.Titik paling nyaman menurut responden adalah titik 2 dengan TE rata-rata berkisar 27,4˚C, kelembaban udara rata-rata berkisar 52,2%, kecepatan udara rata-rata berkisar 0,15 m/s, PMV berkisar 0,5 dan PPD berkisar 12,7%. Dengan begitu semakin kecil ukuran skylight terbukti mempengaruhi kenyamanan termal dan membuat kenyamanan termal dapat tercapai. Kata Kunci: Mall, Clerestory, PMV, PPD, Kenyamanan Termal ABSTRACT Nowadays mall is decorated with clerestory as an effort to lighten naturally during the day. However, sunlight in the afternoon (west) will produce more sunlight and glare than sunlight in the morning (east). Therefore, with the use of a fairly large clerestory in buildings, the problem of heat certainly can not be avoided. Similarly, glare that comes from the reflection of sunlight. One of the malls that use clerestory is BSD AEON Mall. Measurement of air temperature, effective temperature, air humidity, wind speed, PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) carried out at 4 times within 5 measuring spots that have different conditions, proving that clerestory can affect thermal comfort. It was concluded that point 2, which is the point adjacent to the right side clerestory (smaller in size than the left side clerestory) has an effective temperature and lower air humidity than other points, and air velocity (affected by blowing AC) is higher than other points. Respondents felt comfortable when they were at that point. The most comfortable point according to respondents was point 2 with TE averaging around 27.4˚C, air humidity averaged 52.2%, the average air speed ranged from 0.15 m / s, PMV ranges from 0.5 and PPD ranges from 12.7%. Thus, the smaller size of the clerestory is affecting thermal comfort and thermal comfort can be achieved. Keywords: Mall, Clerestory, PMV, PPD, Thermal Comfort

Using Data

Aim. To study the motor activity of sheep of the Zabaykal (Transbaikal) and Agin breeds in year‐round grazing in relation to the season of the year.Material and Methods. The research was carried out in the steppe zone of the Aginsky District of Zabaykalsky Territory. Garmin eTrex 20x GPS receivers were used in the research with the help of which motor activity and the speed of sheep in pasture were monitored. Weather conditions were taken into account for the relevant research periods using data from the meteorological service.Results. Average daily air temperature in winter was – 23.30°C, air velocity 1.3 m/s and relative air humidity 67.3%, and in spring was 13.70°C; 4.1 m/s and 35.6%, in summer – 20.90°C; 1.6 m/s and 77.3% and in autumn – 1.10°С below zero, 2.4 m/s and 50.1%. It was found that the sheep being monitored travelled different distances with different speeds of movement depending on the season of the year and origin. They travelled the greatest distance in winter with a higher average speed of movement and a shorter distance in the summer. At the same time, it was noted that semi‐coarse‐wooled (Agin) sheep passed 12378 m during the 8‐hour grazing period, which is 24.9% more than fine‐wooled (Zabaykal) sheep (Р˂0.01), in spring – 8,168 m (22.3% more, Р ˂0.05), summer – 6,511 m (24.5% more, Р˂0.01) and autumn – 9,214 m (40.3% more). The average speed of movement of semi‐coarse‐wooled sheep was higher than fine‐wooled by 80.0% (P˂0.05), 25.0, 9.1 and 23.1% (P˂0.05), respecƟvely. The nutritional value of 1 kg of dry matter of pasture grass was higher in the summer and amounted to 0.68 units with a content of 1 unit 93.1 g of digestible protein. Conclusion. The research data allow us to conclude that the motor activityand the speed of movement of sheep in pasture directly depends on the season of the year and the nutritional value of pasture grass, as well as on type of breed.

Использование микробных препаратов — перспективный путь повышения продуктивности сельскохозяйственных растений. В статье приведены результаты изучения влияния биопрепаратов, созданных на основе живых штаммов микроорганизмов Bacillus subtilis («Натурост»), Lactobacillus buchneri («Натурост-Актив») и Bacillus megaterium («Натурост-М»), на продуктивность и питательную ценность райграса однолетнего и клеверо-тимофеечной смеси. Исследование проводили в мелкоделяночном полевом опыте во ФГБУН ВолНЦ РАН (Вологодская область) в 2019–2020 годах. Под влиянием обработки биопрепаратами выход зелёной массы райграса возрастал на 13,7–65,5% в зависимости от опытного варианта. Продуктивность травосмеси клевера и тимофеевки увеличилась на 13,1–46,6% в зависимости от используемого биопрепарата, укоса и года исследования. Оценка питательной ценности райграса показала, что обработка биопрепаратами способствовала повышению содержания кормовых единиц в сухом веществе на 6,5%, также несколько увеличилось содержание обменной энергии, сырого и переваримого протеина, сахаров и жиров. Питательная ценность клеверо-тимофеечной смеси по содержанию кормовых единиц под влиянием биопрепаратов увеличилась на 15%. В опытах с райграсом бόльшая продуктивность зелёной массы получена при использовании препарата «Натурост-Актив», в опытах с клеверо-тимофеечной смесью отмечена бόльшая эффективность препарата «Натурост». В исследованиях 2019 года повышение питательной ценности зелёной массы у обеих культур в большей степени происходило под влиянием препарата, созданного на основе бактерий Bacillus megaterium. В 2020 году более выраженное увеличение содержания кормовых единиц, обменной энергии, сырого протеина, переваримого протеина и жиров происходило при внесении препарата на основе бактерий Bacillus subtilis. Microbial preparations were shown to be promising when increasing crop productivity. This article reports on the effect of biopreparations containing living strains of Bacillus subtilis (“Naturost”), Lactobacillus buchneri (“Naturost-Aktiv”) and Bacillus megaterium (“Naturost-M”) on the yield and nutritional value of annual ryegrass and clover-timothy mixture. Microplot field trial took place in 2019–2020. Biopreparations improved green mass yield of ryegrass by 13.7–65.5%. The productivity of the clover-timothy mixture increased by 13.1–46.6% affected by biopreparations, cut and year. Treatment with biopreparations increased feed unit content by 6.5% in dry matter (DM) as well as exchange energy, crude and digestible protein, sugar and fat. Biopreparations improved feed unit content of the clover-timothy mixture by 15%. Ryegrass produced the highest yield of green mass under “Naturost-Aktiv” application, while “Naturost” was more effective for the clover-timothy mixture. In 2019 Bacillus megaterium had the best effect on the nutritional value of crop green mass. The contents of feed units, exchange energy, crude and digestible proteins as well as fat grew significantly after Bacillus subtilis application in 2020.

The Hours

&lt;p&gt;This research is a general reflection of the possible transmission not only of COVID-19 but of any influenza disease depending on environmental parameters such as solar radiation, air humidity and air temperature (vapor pressure deficit), evoking the Penman-Monteith model regarding the evaporation of the water that constitutes the small water droplets (aerosols) that carry the virus. In this case the evapotranspiration demand of the atmosphere with which it can be deduced that the spread of the disease will be higher in those places with less evaporative demand, that is, high air humidity and / or low temperatures, and / or low radiation intensities, and vice versa. It can also be deduced that the hours of greatest potential contagion are the night hours, while those with the lowest risk are between 2:00 p.m. and 4:00 p.m. On the other hand, in those rooms with low temperatures the contagion would be more effective. So, considering that the drops produced by a sneeze, by speaking or breathing can go beyond two meters away, it is roughly explained that the use of face masks and keeping a safe minimum distance of two meters can limit transmission of viruses and / or infections. However, this practice is not entirely safe as the environment can play an important role. What is recommended to reduce the spread of these pathogens is to produce high evaporative demands: increasing solar radiation, and increasing air temperature and reducing air humidity, which is practice that can be effective in closed rooms.&lt;/p&gt;

&lt;p&gt;In the Hidegv&amp;#237;z Valley experimental catchment in Hungary the meteorological data have been collected since the 1990s and used for various purposes including hydrological studies. Current research began in 2018&amp;#8211;19, that aimed to reveal the connections between the hydrological and botanical characteristics in riparian forests and a wet meadow. Changes that occurred in both ecosystems in the groundwater levels, soil moisture and vegetation, showed that the local meteorological events influence these factors. Therefore we decided to analyse longer periods in which meteorological extremes&lt;br&gt;strongly influenced hydrological conditions and so status of ecosystems. Further measurements and their analysis were also required because more accuracy and detail were needed for future water balance modelling.&lt;/p&gt;&lt;p&gt;The measured data between 2017&amp;#8211;2020 were chosen as a starting database. For the first analysis we selected three meteorological parameters, i. e. the precipitation, the air temperature, and the air humidity. These parameters were measured by automated instruments, except for the precipitation. We found that the automated tipping-bucket rain gauge needs validation by a manual measurement (Hellmann-type rain gauge), because the data that collected by the automated device will be invalid if the rain intensity is too high.&lt;/p&gt;&lt;p&gt;In 2017 and 2018, the annual precipitation was distributed evenly, but in the following two years we observed some extremes. In 2019 and&lt;br&gt;2020, the spring was especially dry, the lowest monthly sum was 1.2 mm in 2020 April. 2019 April was similar (19.5 mm), but after the drought&lt;br&gt;period intense rainfall events arrived in May, resulted a monthly total of 214.1 mm. Air temperature and air humidity has not been showed such extremes as the precipitation.&lt;/p&gt;&lt;p&gt;This study showed that detailed analysis of meteorological parameters is crucial for hydrological modelling data preparation because errors and extreme event can cause serious problems during modelling process and, also in case of evaluation of model results.&lt;/p&gt;&lt;p&gt;The research has been supported by the Ministry of Agriculture in Hungary.&lt;/p&gt;

The Impact

This paper focuses on thermocouple air temperature measurement uncertainty due to the radiative fluxes present in the engine compartment where engine case skin temperature can exceed 900 K. To really measure air temperature, the convective heat flux in the thermocouple bead must be predominant. This is why heat shields are used in order to reduce the radiative heat flux on the bead. However, in engine compartment, the heat shield orientation must be optimized since numerous hot walls surround the thermocouple. In order to evaluate the impact of badly oriented heat shields and to provide a data bank for numerical simulation validations, a heated wind tunnel has been used. It has been shown that the uncertainty on the thermocouple temperature can reach dozens of degrees depending on the air speed and the heat shield orientation. Furthermore a specific 3D thermocouple model has been build and validated by comparison with the lab measurements. Then this thermocouple 3D model has been integrated in the whole engine compartment aero-thermal model in order to quantify the uncertainty of the thermocouple air temperature measurement in the real engine environment.

Abstract Currently, there is a rising trend for commercial buildings to use air conditioning to provide indoor thermal comfort. This paper focuses on the impact of prolonged exposure to indoor air-conditioned environments on occupants' thermal acceptability and preferences in a mixed-mode building in Brazil. Questionnaires were administered while indoor microclimatic measurements were carried out (i.e., air temperature, radiant air temperature, air speed and humidity). Results suggest significant differences in occupants' thermal acceptability and cooling preferences based on thermal history; differences were found between groups based on different physical characteristics (i.e., different gender and body condition). The findings also indicated a significant potential to implement temperature fluctuations indoors when occupants are exposed to air conditioning environments in warm and humid climates.

Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya. Upaya peningkatan hasil bayam merah salah satunya dengan pemupukan untuk menambah nutrisi yang dibutuhkan tanaman.

The long-term average value of the studied indicator was 9.52 MJ / kg, which is 5.54% higher than the norm. The highest content of exchangeable energy was noted in 1996 - 9.67 MJ / kg, which is 1.58% higher than the long-term average. The lowest content of exchangeable energy was established in 2009 (9.36 MJ / kg). The long-term average value of the net energy level of lactation was 1.96 MJ / kg, which is 9.68% higher than the norm. The maximum was observed in 2017 and amounted to 2.17 MJ / kg, and the minimum - in 2001 (1.65 MJ / kg), when it was 23.97% below the norm. It was found that the average long-term value of the level of digestible protein in haylage was 111.31 g / kg, which is 1.78% higher than the norm. The highest content of digestible protein was found in 2010 (17.21%). The smallest value was recorded a year earlier, in 2009 and amounted to 95.64 g / kg, which, respectively, is lower than the average long-term value and the value of the norm by 14.08 and 12.56%, respectively.
