W artykule przedstawiono rezultaty wieloletnich badań autorów nad zmianą temperatury względnej węgla w pokładach pod wpływem desorpcji metanu, prowadzonych w Głównym Instytucie Górnictwa. Pozwoliły one na opracowanie kryteriów, metody i aparatury pomiaru temperatury względnej węgla w strefie okołoprzodkowej pod wpływem desorpcji metanu i zachodzących procesów endotermicznych. Przedstawiono propozycję zastosowania pomiaru temperatury względnej węgla w pokładach nasyconych metanem dla bieżącej oceny stanu zagrożenia metanem oraz zjawiskami gazogeodynamicznymi w strefie okołoprzodkowej. Przedstawiona metoda pomiarowa i aparatura pozwalają szybciej i dokładniej ocenić rzeczywiste zagrożenie metanowe i zagrożenie zjawiskami gazogeodynamicznymi w drążonych wyrobiskach, w pokładach nasyconych metanem.
The paper discusses the method and apparatus for non-contact measurement of temperaturę of the coal mass within prospecting boreholes, with the aim of making a current prognosis of the hazard due to the outburst of methane and rock in driven mine headings, and of determining the buffer zone to protect the heading against unexpected outbursts. The probe to control borehole temperature operates on the basis of non-contact measurement of temperaturę. It is designed to perform continuous measurements of the relative temperature along the walls of the prospecting borehole with the diameter of 50-90 mm, and to determine the outburst hazard zones in the coal headings of the mine workings. The measurement of temperature along the borehole, realised by means of the probe, is aimed at locating the hazard zone (HZ) in respect of the outburst, and at simultancous determining the buffer safety zone (BSZ). The determination of HZ and BSZ zones is of vital importance for safety of mining crews employed at driving the workings in coal seams endangered with outbursts of methane and rock. The HZ zone provides information on the location of oceurrence of the hazard zone in respect of the outburst ahead of the front of the driven working. In turn, the BSZ zone defines the thickness of the stress-relieved and degassed protective coal mass, protecting the heading against a direct contact with the BSZ zone.

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 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.

W artykule przedstawiono zróżnicowanie przestrzenne temperatury oraz wilgotności powietrza w rejonie Kaffiøyry (NW Spitsbergen) w sezonie letnim 2014 r. Na podstawie pomiarów na stanowiskach położonych na różnych wysokościach nad poziomem morza przeanalizowano zmiany temperatury i wilgotności powietrza w pionie, obliczono pionowe gradienty tych elementów. Uzyskane wyniki odniesiono do pionowych sondaży atmosfery wykonywanych w pobliskiej stacji w Ny Ålesund. Temperatura oraz wilgotność względna powietrza wykazują znaczne zróżnicowanie przestrzenne. Relacje między stanowiskami zmieniają się z dnia na dzień w zależności od rodzaju mas powietrza oraz zachmurzenia. Stwierdzono również zmienność pionowych gradientów temperatury i wilgotności względnej powietrza w cyklu dobowym.
This article presents the spatial diversity of temperature and relative humidity of the air in the area of Kaffiøyra (NW Spitsbergen). In the summer season of 2014 (21 July – 31 August), observations were carried out at 9 measurement points equipped with temperature and humidity recorders. The points were located in two terrain profiles: the mountains where the highest point was situated at 590 m a.s.l. in the Prins Heinrichfjella range and from the terminal moraines to the firn field (375 m a.s.l.) of the Waldemar Glacier. On the basis of the measurements taken at the sites situated at different absolute heights vertical changes in air temperature and humidity were analysed and lapse rate of air temperature gradients were determined. The results were referenced to vertical atmospheric soundings carried out at the nearby station in Ny Ålesund. The air over NW Spitsbergen (Ny Ålesund) demonstrated a mean vertical lapse rate of 0.61˚C/100 m at the atmospheric layer up to six or seven hundred metres. On most days normal stratification was observed, where temperature fell with height, on 3 days a ground-level air temperature inversion occurred and on 9 days a temperature inversion occurred in the free troposphere. In the area of Kaffiøyra, air temperature decreased with height from 5.5°C on the coast (KH) to 2.5°C at 590 m a.s.l. (PH2). On the Waldemar Glacier, the mean air temperature ranged from 5.0°C on the moraines (ATA) to 3.6°C on the firn field (LW2). The relationship between the sites changed on a daily basis, depending on the cloud amount, insolation and local circulation (e.g. connected with the influence of foenic wind). Averaged lapse rate in relation to the coast (KH) reached between 0.84°C/100 m (LW1-KH) and 0.39°C/100 m (KU-KH) or 0.40°C/100 m (ATA-KH). The mountain tops (PH1 and PH2) are also distinguished by their smaller lapse rate. An inversion in the vertical distribution of air temperature was also frequent and, for example, at the KT site it occurred at 33.9% of the hours and at 28.7% at ATA. On the Waldemar Glacier, inversion occurred at a frequency of 16.3% at its front (LW1) to 8.8% at its firn field (LW2). On the mountain tops, the inversion occurred at a frequency of 18% (PH2). The relative humidity of the air over Spitsbergen is high due to the prevalence of maritime air masses. According to the soundings conducted at Ny Ålesund, the humidity increased with the height, however in 13 cases a vertical inversion of relative humidity occurred – the overground air layers proved more saturated with water vapour. On Kaffiøyra, the average relative humidity of the air was 87.7% and increased up to approx. 500 m, above which it slightly dropped. This results from a high frequency of occurrence of Stratus clouds which do not reach the higher tops. The vertical gradients of relative humidity were diverse: at most sites, the relative humidity increased with the height, for example at the PH1 site, the gradient was 3.12%/100 m. A greater diversity of the relative humidity was typical of the hours around midday.

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.

Opisano zmienność wartości wybranych elementów meteorologicznych i charakterystyk klimatycznych w skali czasowej, wykorzystując najczęściej stosowane statystyki rozkładu, tzn. wartości średnie oraz miary zmienności. Wyznaczono kierunek trendu zmian temperatury powietrza. W celu określenia warunków bioklimatycznych obliczono wartości wybranych wskaźników, takich jak: temperatura ekwiwalentna, temperatura efektywna i wielkość ochładzająca powietrza. Przeprowadzone badania wskazują, że w Zamościu optymalne warunki termiczne określane jako przyjemnie chłodno występują w okresie letnim (czerwiec, lipiec, sierpień), przy czym w lipcu są one łagodne. W kwietniu, maju i we wrześniu odczucie cieplne charakteryzowane jest jako chłodne. Generalnie w okresie od listopada do marca jest zimno, a w styczniu i w lutym bardzo zimno.
The paper uses data from meteorological stations operating in Zamość in the period from 1976 to 2020. The variability of the values of selected meteorological elements and climatic characteristics on a time scale was presented using the most commonly used distribution statistics, i.e. average values and variability measures. The direction of the trend of changes in air temperature was determined as well. In order to determine the bioclimatic conditions, the values of selected indicators were calculated, including equivalent temperature, effective temperature, and air cooling quantity. The conducted research indicates that in Zamość optimal thermal conditions described as pleasantly cool occur in the summer ( June, July, August), while in July they are mild. In April, May and September, the thermal sensation is characterized as cool. Generally, it is cold from November to March and very cold in January and February.
