Current methods for estimating heat vulnerability of young athletes use a heat index (HI) or a wet bulb globe thermometer (WBGT), neither of which fully include the environmental or physiological characteristics that can affect a person’s heat budget, particularly where activity occurs on a synthetic surface. This study analyzed and compared the standard methods, HI and WBGT, with a novel and more comprehensive method termed COMFA-Kid (CK) which is based on an energy budget model explicitly designed for youth. The COMFA model was presented at the same time to demonstrate the difference between a child and an adult during activity. Micrometeorological measurements were taken at a synthetic-surfaced football field during mid-day in hot environmental conditions. Standard methods (HI and WBGT) indicated that conditions on the field were relatively safe for youth to engage in activities related to football practice or games, whereas the CK method indicated that conditions were dangerously hot and could lead to exertional heat illness. Estimates using the CK method also indicated that coaches and staff standing on the sidelines, and parents sitting in the stands, would not only be safe from heat but would be thermally comfortable. The difference in thermal comfort experienced by coaches and staff off the field, versus that experienced by young players on the field, could affect decision making regarding the duration and intensity of practices and time in the game. The CK method, which is easy to use and available for modification for specific conditions, would lead to more accurate estimates of heat safety on outdoor synthetic surfaces in particular, and in sports with a high prevalence of heat illness such as football, and should be considered as a complementary or alternative preventive measure against heat.

Aim of the research was to find out and compare individual subsystems of selected types of aggressiveness and individual types of hostility within age categories of learners of sports hockey classes. Research sample consisted of sixth, seventh, eighth and ninth grade boys from primary schools. Age of learners varied from 11 to 14 years. Total sample consisted of 120 learners. The research was it was implemented with the help of a standardized psychological questionnaire B – D – I. In the results we‘re comparing the differences in individual subspecies of aggressive behaviour and also in overall aggressiveness between younger and older learners grade. It turned out that in all of the observed comparisons older learners achieved higher average values of the weighted score than younger. The difference was confirmed also by the nonparametric Mann Whitney U test, which at the unilateral test of 5 % level of demonstrability tells that between younger and older learners there‘s statistically significant difference p = 0.031. Also, any increased value of the resentment didn‘t occur neither among younger learners who achieved the average value of the weighted score 4.19 nor among older learners with the average value of the weighted score 4.81 and therefore there is not statistically significant difference (p = 0.681). Our research revealed that controlling emotions such as aggression is very important. Therefore, it‘s important to pay enough attention to the young athletes and their coaches to prevent any manifestations of aggressiveness from their performers and to encourage them to play fair-play sports.

The Difference

Many cases are related to corrections caused by the occurrence of VAT and Income Tax equalization. The difference in reporting the circulation of business on the VAT SPT with the Corporate Income Tax Return is the object of the tax authorities' examination. Basically, equalization is not to find the same number of circulation businesses but to find the cause of the difference between the VAT Period of Income Tax and the Corporate Income Tax Return. These differences are often due to differences in provisions between Income Taxes and Value Added Taxes, such as tax objects, exchange rates, and so on. The purpose of this study was to find out how to report the circulation of business between the VAT Period of VAT and Corporate Income Tax Returns of PT. AdiyanaTeknikMandiri. To find out the process and analysis of equalization between VAT Period of VAT and Corporate Income Tax Returns at PT. AdiyanaTeknikMandiri. To find out the equalization benefits of the VAT Period SPT with Corporate Income Tax Returns for companies. This study uses a comparative descriptive method with qualitative and quantitative data, namely by analyzing and processing financial statement data and existing fiscal reports, then comparing the circulation of business to the results of calculations according to the VAT Period of VAT and Corporate Income Tax Returns, then processed further to provide an explanation of the difference in business circulation generated. The results of this study indicate that PT. AdiyanaTeknikMandiri that the company in reporting the circulation of its business has not been reported as it should, it is known after equalizing it is known that there is a number of business circulation that has not been reported in the VAT Period SPT report so that it causes a difference in the amount of business circulation between the VAT Period of Income Tax and the Corporate Income Tax Return. Equalization process is carried out by comparing the VAT Period report with the Corporate Income Tax Return, collecting data on business circulation in the ledger, comparing the data obtained, then analyzing the factors that cause the different reporting of business circulation. Equalization benefits for the company, which can be a preventive measure to face a tax audit by the tax authorities, so that the company can explain in accordance with the conditions that occur, equalization can also be a benchmark of compliance and increase the accuracy of taxpayers in reporting the amount of tax obligations in accordance with the applicable law .   Keywords: tax equalization, business circulation, corporate income tax return

ObjectivesTo conduct a document and content analysis of exertional heat illness (EHI)-related documents published by sports organisations in Victoria, Australia, in order to determine their scope and evidence base against current international best practice recommendations.MethodsA qualitative document and content analysis. Official documents relating to EHI were identified through a search of 22 Victorian sport organisation websites, supplemented by a general internet search. The content of these documents was evaluated against recommendations presented in three current international position statements on prevention and management of EHI.ResultsA range of document types addressing EHI were identified (n=25), including specific heat policies, match day guides, rules and regulations. Recommendations about prevention measures were the most common information presented, but these were largely focused on event modification/cancellation guidelines only (n=22; 88%). Most documents provided information on hydration as a preventive measure (n=20; 80%), but the emphasis on the importance of cooling strategies (n=7; 28%) and heat acclimatisation (n=5; 20%) was inadequate. Details on EHI, including its definition, symptoms/signs to look out for, and common risk factors (beyond humidity/high temperatures) were lacking in most documents.ConclusionThere is considerable variation in formal documents with regard to their content and quality of information. Continued efforts to bridge the evidence to practice gap in sports safety are therefore important. This study highlights the challenge for community sport, which relies on high-level policy and governance, across settings and populations that can differ substantially in their needs.

Abstract Diurnal sea surface warming affects the fluxes of latent heat, sensible heat, and upwelling longwave radiation. Diurnal warming most typically reaches maximum values of 3°C, although very localized events may reach 7°–8°C. An analysis of multiple years of diurnal warming over the global ice-free oceans indicates that heat fluxes determined by using the predawn sea surface temperature can differ by more than 100% in localized regions over those in which the sea surface temperature is allowed to fluctuate on a diurnal basis. A comparison of flux climatologies produced by these two analyses demonstrates that significant portions of the tropical oceans experience differences on a yearly average of up to 10 W m−2. Regions with the highest climatological differences include the Arabian Sea and the Bay of Bengal, as well as the equatorial western and eastern Pacific Ocean, the Gulf of Mexico, and the western coasts of Central America and North Africa. Globally the difference is on average 4.45 W m−2. The difference in the evaporation rate globally is on the order of 4% of the total ocean–atmosphere evaporation. Although the instantaneous, year-to-year, and seasonal fluctuations in various locations can be substantial, the global average differs by less than 0.1 W m−2 throughout the entire 10-yr time period. A global heat budget that uses atmospheric datasets containing diurnal variability but a sea surface temperature that has removed this signal may be underestimating the flux to the atmosphere by a fairly constant value.

AbstractMost climate models treat surface and atmospheric properties as being horizontally homogeneous and compute surface radiative fluxes with average gridcell properties. In this study it is found that large biases can occur if sub-gridcell variability is ignored, where bias is defined as the difference between the average of fluxes computed at high resolution within a model cell and the flux computed with the average surface and cloud properties within the cell. Data from the Advanced Very High Resolution Radiometer for the year-long Surface Heat Budget of the Arctic Ocean (SHEBA) experiment are used to determine biases in aggregate-area fluxes. A simple regression approach to correct for biases that result from horizontal variability was found to reduce the average radiative flux bias to near zero. The correction can be easily implemented in numerical models.

Background: In this study, the ferrous sulfate was used to remove Cr(VI) and Ni(II) ions from a real Ni-Cr plating industry wastewater. Methods: This is an applied study. The type of sampling was composite by three 5 L containers. Wastewater chemical and physical characteristics were measured in accordance with the standard methods. The concentration of un-removed metal ions was estimated by ICP-OES. The Jar test was used to carry out the chemical coagulation experiment. The results indicated that the rate of removal depended on the pH of 1.5-11, the diverse contact time of 30-120 min, and the coagulant measurement ranging from 0.5-2 g/l. Results: The optimum removal of Cr(VI) ions was observed at a pH of 7 up to 83.88% in 0.5 g/l of coagulant for 40 min. While the optimum removal of Ni(II) ions was found at a pH of 5 up to 56.33 % in 0.5 g/l of coagulant for 40 min. The scanning electron microscopy results revealed the difference between the coagulant surface while coagulation. Also, the Energy-Dispersive X-ray spectroscopy (EDX) analysis showed the presence of Cr(VI) and Ni(II) ions on the surface of the ferrous sulfate after coagulation. Conclusion: Ultimately, the results indicated that ferrous sulfate could be an operative chemical coagulant to remove Cr(VI) and Ni(II) ions from the plating industry wastewater, especially for Cr(VI) particles. The results of this study can be a useful guide to the real plating industry wastewater treatment operators.

West Pasaman Regency in West Sumatra Province is recently established as an administrative area on 2003, segregated from Pasaman Regency where it was previously affiliated. This regency has been planning to support its structural developments using its main income generated from agricultural sector, which involve vast plantation area for oil-palm and other agricultural products. With the variety of its topography spans from some offshore islands up to 2,912 m mountain area, it is interesting to understand the importance value of this area from the perspective of one of its natural biodiversity: avifuna. Here in this paper, we use Genetic Heat Index (GHI) concept based on avian diversity and their conservation status to compare the significance value among four prominent landscapes in this regency, which include Mount Talamau and Laut Tinggal Lake (mountainous area), Tongar River (lowland-to-hilly riparian agricultural area) and Panjang Island (an offshore island). Despite the difference and similarity of bird species recorded in each site, Panjang Island has comparable GHI value with Tongar River, Mount Talamau and Laut Tinggal Lake (consecutively 4.20, 4.03, 4.14, 4.26). This result implies to the uniqueness of bird species living in each site along with its habitat typicality which also helps in contributing to their GHI value. Therefore, giving attention to this GHI concept while accommodate it into development plan will help in supporting more environmentally-sound development process.

The article presents the indicators of physical fitness and coordination abilities of young athletes 10-11 years old. Under the influence of specific physical loads in accordance with the chosen kind of sport, data on speed and speed- power qualities were obtained, as well as the level of coordination abilities of young athletes of 10-11 years old. Objective. To determine the coordinating abilities of young athletes 10-11 years old during nine months of training in the chosen kind of sport. Skiing and cycling are extreme sports. But the material, technical, scientific and methodological support in these sports in Ukraine is at an insufficient level in comparison with Europe and America. Numerous studies have shown that the development of coordination abilities at a young age at the initial stage of long-term training must be combined with technical training. It is also noted that it is impossible at a young age to predict an athletic result in a chosen sport without taking into account the functional features and especially technical skill. At the present stage, there is no doubt that the high intensity of use in the training process of exercises that provide the maximum efficiency of specific exercises of a coordination orientation. At the same time, one-sided emphasis on technical training, especially at the initial stages of sports training, following the data of researchers, leads to limitation of motor actions. Therefore, our research is devoted to a relevant topic. The physical fitness testing of 10-11 year old sportsmen, carried out by us at the beginning and at the end, showed positive dynamics in all indicators. Statistical changes were determined in cyclists relative to skiers in pulling up on the crossbar, in raising the legs on the crossbar, in jumping over a log in 20 s, in long jump from a place (p <0,05). The training methodology introduced into the training process of young cyclists positively influenced the level of coordination abilities of young athletes of 10-11 years old. The growth rate turned out to be 8,4 % higher in walking on an 8-meter bench, by 7,0 % in the difference between a 15-meter run and a 15-meter slalom run, by 4,2 % in a 10-meter shuttle run 3 cubes each for cyclists relative to skiers.

And Performance

This article introduces the concept, use and implementation of method noise in the field of synthetic aperture radar (SAR) image despeckling. Method noise has the capability to enhance the efficiency and performance of any despeckling algorithm. It is easy, efficient and enhanced way of improving the results. The difference between speckled image and despeckled image contains some residual image information which is due to the inefficiency of the denoising algorithm. This article will compare the results of some standard methods with and without the use of method noise and prove its efficiency and validity. It also shows its best use in different ways of denoising. The results will be compared on the basis of performance metrics like PSNR and SSIM. The concept of method noise is not restricted to only SAR images. It has vast usage and application. It can be used in any denoising procedure such as medical images, optical image etc. but this paper shows the experimental results only on the SAR images.
