Opis:
The effects of climate change on agriculture may have strong impacts on the world’s food economy and are likely to threaten both the welfare of the world’s population and the economic development of the global society. Hence, the impacts of changes in important climate variables like temperature, rainfall and relative humidity on the production of a major food commodity called banana is investigated using the data obtained within 1998-2012 from Ondo State, Nigeria. The results suggest that excessive rainfall and extremely high temperature can reduce banana productivity while the production is also small when both rainfall and temperature are very low with poor humidity. On the average, the findings show that a mean temperature of about 26 °C and average rainfall of around 1891mm with relative humidity of approximately 77% will lead to good annual banana production above 61,000 tons in Ondo State. Since these climate variables will fluctuate under a future climate change condition, the coping strategies recommended for farmers in the area and in similar places might include planting of drought- and disease resistant banana types, monitoring of weather conditions, use of irrigation and chemicals. Improved storage facilities are also important while transportation of banana should be done under controlled conditions to avoid spoiling the quality.

Opis:
Soldiers can wear chemical, biological, radiological and nuclear (CBRN) protective clothing to be protected agaist warfare agents. The disadvantage of that clothing is that higher protection introduces higher physiological burden. Therefore an optimum between comfort and protection must be found. Models of all relevant processes were created to find this optimum. The airflow profile around a cylinder with clothing—representing a dressed human body part—was modelled. This flow profile was used for calculating the agent vapour breakthrough through the clothing and for calculating the deposition of agents onto the skin (as indicators for protection). The flow profile was also used for calculating the temperature profile around the body part and the relative humidity underneath and in the clothing (as representative for physiological burden). As a result a tool was created, which can be used to identify the optimum properties of CBRN protective clothing, depending on the intended mission of the soldiers.

Opis:
The variability in the temperature and Relative Humidity (RH) observed within Lagos State, a coastal region in Nigeria, is investigated using data from Nigeria Meteorological Agency (NIMET) for 1980 to 2010. The results reveal an annual mean value of 27.20°C and 83.01% for the temperature and RH respectively and an increasing trend in RH over the study period while such rising trend in the mean temperature is reversed from 2005 to 2010. The findings show an inverse relationship between the temperature and RH while it further indicates that low temperature is associated with increased rainfall under the accompanying cloudy condition and vice versa. These observations are supported by the strong correlation coefficients between the RH and the rainfall (0.72) and that between the RH and the temperature (-0.95) while -0.59 is obtained between the rainfall and the corresponding temperature. The correlations show that the impacts of the precipitation on RH are stronger than the effects it has on the temperature while both temperature and RH strongly depends on each other. Hence, under a future global warming, extremely warm atmospheric condition characterized by high RH in the coastal region could cause heat stroke, discomfort and health problems among the inhabitants. However, the area becomes conducive and attractive to tourists under moderate RH and good temperature.

The accuracy of the available from the literature models for the dew point temperature determination was compared. The proposal of the modelling using artificial neural networks was also given. The experimental data were taken from the psychrometric tables. The accuracies of the models were measured using the mean bias error MBE, root mean square error RMSE, correlation coefficient R, and reduced chi-square χ2 . Model M3, especially with constants A=237, B=7.5, gave the best results in determining the dew point temperature (MBE: -0.0229 – 0.0038 K, RMSE: 0.1259 – 0.1286 K, R=0.9999, χ2 : 0.0159 – 0.0166 K2 ). Model M1 with constants A=243.5, B=17.67 and A=243.3, B=17.269 can be also considered as appropriate (MBE=-0.0062 and -0.0078 K, RMSE=0.1277 and 0.1261 K, R=0.9999, χ2 =0.0163 and 0.0159 K2 ). Proposed ANN model gave the good results in determining the dew point temperature (MBE=-0.0038 K, RMSE=0.1373 K, R=0.9999, χ2 =0.0189 K2 ).

The thesis presents the analysis of development of selected parameters of microclimate in a standalone cellar plunged into soil. The scope of studies included measurement of air internal and external temperature and relative humidity of internal and external air. The thesis also concerns the analysis of heat exchange of cellar compartments with the surrounding soil. The studies were carried out from July 11, 2012 to July 10, 2013. The analysis of the obtained results of studies proved that the internal air temperature in the examined cellar was mainly formed by the external air temperature as well as by the surrounding soil. For 42% of storage period, the thermal conditions in the cellar plunged into soil were unfavorable which disqualifies the cellar’s purpose for storage of vegetables, e.g. potatoes. Too high temperature was observed in the initial and final period. Favorable storage conditions were experienced only in the period from December 14, 2012 to April 11, 2013. To adjust this kind facility for storage of vegetables, thermal insulation of compartments and installation of cooling units is required.

A class first Pyranometer was used to measure the direct solar irradiation and the obtained results were analyzed. Separate sensors were used to measure the relative humidity and the atmospheric temperature (RH/AT sensors). The measurements were conducted for the whole year of 2013. The author analyzed the collected solar data during one day, month, and year. The maximum, minimum, average, and accumulative solar irradiation (SR) were calculated and analyzed with connection to relative humidity and atmospheric temperature. The author found that April was characterized by the average maximum solar irradiation (SR= 1112±1W/m2), May had the maximum SR accumulation (13276552± 1W/m2). The maximum average percentage relative humidity found in July (% RH = 97± 3%), while the minimum average % RH is in December (% RH = 25± 3%). In May, the maximum average atmospheric temperature was 36.0 ± 0.6°C, while the average minimum was in January (AT= 19.1 ± 0.6°C). The total accumulation of solar flux during the year 2013 is 222 ± 1MW/m2.

Opis:
The risk of human exposure to finely-dispersed aerosol particles being airborne indoors is determined by the size and the number concentration of particles, the intensity of an aerosol emission source, the air filtration and ventilation efficiency, etc. The emphasis in this article is on behaviour patterns of aerosol particles when exposed to ultrasonic and electrostatic fields in different conditions of air temperature and relative humidity. Wood flour having sizes of interest (characteristic particle diameter about 10 μm) is chosen as a model aerosol. The article considers a physical and mathematical model presenting the evolution of aerosol particles in external fields, taking into account the moisture content and the temperature of a dispersive medium. The efficiency of ultrasonic and electrostatic precipitation in different relative humidity and temperature conditions in an enclosed space was studied using optical measurement methods of particle size and concentration.

Opis:
The aim of this study was to evaluate the influence of environmental housing conditions on the milk yield of dairy cows. Measurements were taken in the summer period from June to September, 2020 and in the winter period during January, 2021 on a large-capacity farm of Holstein Friesian cattle. Cows were housed in free stall barn with the lying boxes and selected during the second or third lactations, in the summer period from the 51st day to the 135th day and in the winter period from the 64th day to the 120th day of lactation. The average temperature in the housing was 23°C in summer, and 7.05°C in winter. The average THI (thermal humidity index) value in summer was 70.43, but during the day the THI values sometimes reached 75. The dairy cows were therefore exposed to heat stress during summer. Increasing THI and temperature values negatively affected the milk yield, as there was a negative correlation between both THI and milk yield (r = −0.641; p < 0.01) and temperature and milk yield (r = −0.637; p < 0.01). Milk production in winter was at 58.77 kg per day and in summer at 49.55 kg per day. In the summer, the milk had a significantly lower content of fat (p < 0.05), proteins (p < 0.001), lactose (p < 0.001), minerals (p < 0.001) and conversely, a higher number of somatic cells (p < 0.01). These results show that worse environmental conditions during the summer negatively affected the level of milk yield and the composition of the cows’ milk.

Opis:
The main objective of the research was to study the effect of the Stenotaphrum secundatum and Zoysia japonica grasses on the higher and lower environment temperature and lower relative humidity; the secondary objective was to compare whether the Stenotaphrum secundatum grass has a greater impact on the environment parameters of comfort than the Zoysia japonica species. Six materials were used for the extensive green roof, each one forming a layer of the system, which were placed on the concrete slab and in an upward direction, including: PVC geomembrane, Polyester asphalt carpet, Pumice stone, Planar geodren, Prepared soil with guano, compost, muss, and Substrate. In order to make measurements of the higher and lower ambient temperature, a digital thermometer and lower relative humidity meter was used. Stenotaphrum secundatum and Zoysia japonica were used as grass species, as they were the most representative of the grasses used in extensive green roofs. The experimentation was carried out for 2 months from September to October of 2021, having built 3 modules of 1000x600mm roofs, including 1module of the concrete roof with ceramic covering and 2 modules of extensive green roof with two types of grass: Stenotaphrum secundatum and Zoysia japonica. The readings of the environment temperature and relative humidity of the higher and lower part were taken in six points of each module to have a greater number of representative measurements. The watering of the 2 green roof modules with grass was carried out twice a week, applying 5L of water per module. The results indicate that the Zoysia japonica grass is the one that presents a better behavior before the higher ambient temperature and that the Stenotaphrum secundatum grass behaves better before the lower ambient temperature and lower relative humidity. The conclusions indicate that the Stenotaphrum secundatum grass behaves better temperature and relative humidity; the two grass types exhibit different behavior.

Filtration plays a major role in managing the rapid increase of environmental pollution and deterioration of atmospheric air quality. One of the most damaging noxious gases in the atmosphere is toluene, which is a common gas that appears in crude oil and is used in various production processes. The adsorption behaviour of activated carbon was examined in dependence of the concentration, temperature and relative humidity. The results showed that increasing air temperature decreased the time to reach the maximum saturation ratio, which occurred due to the increasing pore diffusion coefficient and pore diffusion rate.

The aim of this study is to compare climatic conditions between the interior of the Iberian Peninsula and the southeastern coast of Spain. The article analyzes selected elements of climate over the last 15 years (2000-2014). Synoptic data from airport meteorological stations in Madrid Barajas and Alicante Elche were used. Attention was focused on annual air temperature, relative humidity and precipitation. The mean climatic conditions over the period 2000-2014 were compared with those over the 1961-1990 period which is recommended by WMO as climate normal and with data for the 1971-2000 coming from ‘Climate Atlas’ of Spanish meteorologists group AEMET. Two of climate elements discussed were characterized by significant changes. The annual air temperature was higher by about 0.2°C in Alicante and 0.9°C in Madrid in the period 2000-2014 compared to the 1961-1990. The current winters were colder than in years 1961-1990 at both stations. Gradual decrease in annual precipitation totals was observed at both stations. In 1961-1990 the annual average precipitation in Madrid amounted to 414 mm, while in Alicante it was 356 mm. However, in the recent years of 2000-2014 these totals were lower compared to 1961-1990 reaching 364.1 mm in the central part of Spain and 245.7 mm on the south-western coast.

Opis:
The aim of this article to present of research results of microclimate parameters in barns with different gravitational ventilation systems and comparison of efficiency of these systems. Two tied-up and three loose-housing barns for dairy cows and one for beef cattle were researched. Tied-up barns had functional attic and duct ventilation, in barns with loose housing systems there were skylights with roof ridge gap. In stalls with ventilation by vertical channels there was not sufficient area of air inflow and outflow. The negative consequence of this was overcoming of recommended internal relative humidity of air (80%) in these stalls. In non-littered barns, with roof- ridge gap ventilation, temperature of air exceeded recommended values of 25oC. The luminance of daily light in stalls with functional attic was below of minimal level, which was described by standards (100 lx).
Celem niniejszego artykułu jest przedstawienie wyników badań parametrów mikroklimatu w oborach z dwoma różnymi systemami wentylacji grawitacyjnej i porównanie skuteczności tych systemów. Zbadano po dwie obory stanowiskowe i wolnostanowiskowe dla krów mlecznych oraz jedną dla bydła mięsnego. Obory stanowiskowe posiadały poddasze użytkowe z wentylacją kanałową, natomiast w pozostałych oborach był świetlik ze szczeliną kalenicową. W oborach z wentylacją pionowymi kanałami nie była zapewniona odpowiednia powierzchnia nawiewu i wywiewu. Negatywnym tego skutkiem było przekroczenie zalecanych wartości wilgotności względnej powietrza (80%) w tych oborach. Temperatura w oborach bezściółkowych z wentylacją kalenicową przekraczała zalecane standardami wartości (25oC). Natężenie oświetlenia dziennego, w oborach z poddaszem użytkowym było poniżej minimalnego poziomu określonego standardami (100 lx).

Opis:
The subject of this paper is to analyse the climate change and its influence on the energy performance of building and indoor temperatures. The research was made on the example of the city of Kielce, Poland. It was was carried out basing on the Municipal Adaptive Plan for the city of Kielce and climate data from the Ministry of Investment and Development.The predicted, future parameters of the climate were estimated using the tool Weather Shift for Representative Concentration Pathways (RCP). The analysis took into consideration the RCP4.5 and RCP8.5 scenarios for years 2035 and 2065, representing different greenhouse gas concentration trajectories. Scenario RCP4.5represents possible, additional radiative forcing of 4.5 W/m2 in 2100, and RCP8.5 an additional 8.5 W/m2. The calculated parameters included average month values of temperature and relative humidity of outdoor air, wind velocity and solar radiation. The results confirmed the increase of outdoor temperature in the following year. The values of relative humidity do not change significantly for the winter months, while in the summer months decrease is visible. No major changes were spotted in the level of solar radiation or wind speed. Based on the calculated parameters dynamic building modelling was carried out using the TRNSYS software. The methodology and results of the calculations will be presented in the second part of the paper.
Przedmiotem artykułu jest analiza zmiany klimatu oraz jej wpływu na charakterystykę energetyczną budynku i temperaturę wewnętrzną. Badania przeprowadzono na przykładzie miasta Kielce. Ich podstawą był Miejski Plan Adaptacyjny dla miasta Kielce oraz dane klimatyczne z Ministerstwa Inwestycji i Rozwoju. Przewidywane, przyszłe parametry klimatu zostały oszacowane za pomocą narzędzia Weather Shift dla Representative Concentration Pathways (RCP). W analizie uwzględniono scenariusze RCP4.5 i RCP8.5 na lata 2035 i 2065, reprezentujące różne trajektorie wzrostu stężenia gazów cieplarnianych. Scenariusz RCP4.5 reprezentuje przewidywane, dodatkowe wymuszenie radiacyjne wynoszące 4,5 W/m2 w 2100 r., a RCP8.5 dodatkowe 8,5 W/m2. Wyznaczone parametry obejmowały średnie miesięczne wartości temperatury i wilgotności względnej powietrza zewnętrznego, prędkości wiatru i wielkości promieniowania słonecznego. Wyniki obliczeń potwierdziły wzrost temperatury zewnętrznej w kolejnych latach. Wartości wilgotności względnej powietrza nie zmieniają się znacząco dla miesięcy zimowych, natomiast w miesiącach letnich widoczny jest ich spadek. Nie zaobserwowano większych zmian w poziomie promieniowania słonecznego i prędkości wiatru.
