Authors: Anikeenko L. 
Published: December 2020

The article analyzes the current state of the problem of sports injuries in football. The most vulnerable areas of injuries in football have been identified. Possible causes of football injuries and the most common situations that lead to injuries in football players have been identified: defensive play, running, abrupt stop to open or get the ball, kick on the ball, abrupt stop to strike, one-step stop to change direction, foot kick on artificial turf, jump through a lying player, blocking, landing after a header, running after the ball, losing balance, driving the ball, blocking the defender, simultaneous with the opponent kick on the ball, loss equilibrium due to the collision.
Among such non-traditional means, in our opinion, there are exercises of adaptive-strengthening character which allow to strengthen the musculoskeletal system of the lower extremities, thereby expanding opportunities of increase of special physical training of football players and decrease in sports injuries. Of course, they should be used in combination with traditional physical and technical-tactical exercises and used as additional factors that contribute to the expansion of the functional boundaries of the musculoskeletal system.
However, the construction of purposeful, specially organized and scientifically sound comprehensive training sessions in the sources we studied was not found, which was the subject of our study. The growing importance of regular exercise, associated with profound changes in lifestyle, requires the development of measures that can ensure high efficiency of physical culture and sports to promote health and improve the performance of the general population

Authors: Rashid Md Bazlur , Hossain Syed Shahadat 
Published: December 2020

In statistical downscaling technique, regional or local information are derived by determining a statistical model which relates large-scale climate variables or predictors generated by Global Climate Models (GCMs) to regional and local variables or predictands. In this paper, the results of GCMs were statistically downscaled to produce future climate projections of mean temperature in the post-monsoon season (October and November), for the time periods 2021-2050 and 2071-2100 for Bangladesh. The future climate projections are based on the three emission scenarios RCP2.6, RCP4.5 and RCP8.5 provided by the fifth Coupled Model Intercomparison Project (CMIP5). This paper established a method to analyze GCMs for use in statistical downscaling and utilized fifteen GCMs. The GCMs were assessed based upon their performance in simulated past climate in Bangladesh and adjoining areas. Downscaling was undertaken by linking large scale climate variables, taken from the ERA-Interim (resolution 79 km) reanalysis temperature, a gridded data set incorporating observations and climate models, to local scale observations. Overall, all fifteen GCMs, via statistical downscaling, show that mean temperature of the post-monsoon season in Bangladesh will increase under future climate scenarios. Comparing the ensemble of future projections with the reference period (1981- 2010), the mean post-monsoon temperature in Bangladesh is projected for RCP8.5 showing warming by 0.310C in near future and 1.790C in far future. On the other hand, estimated warming is 0.390C in near future and 1.140C is far future for RCP4.5. Low emission scenarios RCP2.6, near future temperature is nearly same the far future temperature.

Authors: Faruq Md Omar , Mallik MAK , Chowdhury MAM , Akhter MAE , Hossain M Arif 
Published: December 2020

Topography and orography are two physical factors which produce high impact rainfall over the North-eastern part of Bangladesh. To predict the orographic rainfall of 29 March 2017 over Sylhet, Bangladesh an attempt has been performed using Weather Research and Forecasting (WRF) model. The model has been run in a single domain of 10 km horizontal resolution for 48-h and 72-h using six hourly global final datasets from 0000 UTC of each initial day of the event as initial and lateral boundary conditions with NSSL 2-moment microphysics scheme, Kain–Fritsch cumulous scheme and Yonsei University Planetary Boundary Layer (PBL) scheme. The model outputs such as sea level pressure, wind flow, vorticity, wind shear, humidity, Convective Available Potential Energy (CAPE), Convective Inhibition, Lifted Index, K-index, Total Total Index and rainfall have been analyzed. The model predicted weather parameters were visualized by Grid Analysis and Display System (GrADS) and Geographic Information System (GIS) software and validated with observed data of Bangladesh Meteorological Department (BMD), Tropical Rainfall Measuring Mission (TRMM) and European Centre for Medium-Range Weather Forecasts (ECMRWF) data. The analysis determines that the CAPE of magnitude 800- 1000 JKg-1, positive vorticity of (6-10) ×10-5s-1 and relative humidity of 80-100% up to 500-400 hPa levels are accountable for the happening of the orographic extreme rainfall and other parameters are compatible with the observed or theoretical values. This study indicates that the model with an appropriate model set up is capable to predict the orographic precipitation realistically well and can be used for upcoming events.

Large Scale Processes for Understanding Extreme Rain Storm Over Rangamati on 12 June 2017- A Case Study
Authors: Karmakar Samarendra , Das Mohan Kumar , Sarker Haripada 
Published: December 2020

Attempts have been made to study the large-scale surface and upper air synoptic processes associated with a monsoon depression during 11-12 June 2017. In this study, Grid Analysis and Display System (GrADS) software has been used to prepare the large-scale sea level pressure and upper flow patterns by analyzing the FNL re-analysis data. In this analysis, FNL dataset is used to characterize the rainstorms, with key hydrometeorological variables describing the prior conditions of the very heavy rainfall event presented the study. National Center for Environmental Prediction (NCEP) Final (FNL) analysis data of 1o by 1o grids for every 6 hours are used for large scale synoptic analysis. The disastrous event was a strong monsoon depression in the early period of southwest monsoon 2017. Due to this depression, very heavy rainfall occurred in the southeastern Bangladesh. Rangamati recorded 343 mm of rainfall in the 24 hours on 12 June 2017. Massive landslides occurred in three districts such as Rangamati, Bandarban and Chittagong. The analysis of surface and upper air synoptic conditions has revealed that a well-marked low was formed over the northwest Bay of Bengal within the low-pressure belt passing from Somalia coast extending through southern Pakistan, and India up to east central Bay of Bengal and adjoining Bangladesh. The wind speed is calculated from the pressure distribution and is found to be 24.23ms-1, which is at par with the observed one. The well-marked low was subsequently intensified into a depression and moved northeastwards over Bangladesh. Strong southsouthwesterly winds were associated in the eastern side of the depression, especially over Chittagong Hill Tracts. The depression was found to extend up to 500 hPa level as seen from the distribution of geopotential and strong circulation around the centre. Winds were advecting from large continental and Ocean areas over the South Asia. Strong winds and moisture influx, strong narrow coma-like trough from a micro low at the surface to 500 hPa level as well as strong wind shear were responsible for the heavy rainfall, disastrous effects and massive landslides over Rangamati and adjoining areas.

Authors: Paul Snahashish , Rashid Muhammad Harunur , Rahman Md Anisur 
Published: December 2020

Self Compacted Concrete (SCC) is a material used in the construction industry to ensure proper compaction of concrete without providing any external energy. In case of exposure of SCC to accidental fire, an assessment of its residual capacity is needed. This study covers the observation of residual compressive strength, tensile strength and modulus of elasticity of self compacted concrete under elevated temperatures (150, 300, 450, 600 and 800⁰C) and cooling conditions (air cooling and water quenching). The compressive strength increased at 150⁰C and decreased continuously after this temperature. However, tensile strength and modulus of elasticity decreased at elevated temperatures compared with ambient temperature. The compressive strength at ambient temperature (30⁰C) was 27.0 MPa, and it raised to 28.7 MPa at 150⁰C for air cooling and 27.8 MPa for water quenching.

Online survey for primary data was conducted through 158 respondents and the informants belongs to different types of occupation such as student, govt. employee, businessman etc. Secondary data was obtained from various credential sources. With the socioeconomic stress of COVID-19, people’s satisfaction level is measured with well-known index life scale assessment to measure the judgmental component of subjective well-being. This study reveals that 44% respondents who preferred online based activities which are directly related with online activity and occupation related activities rather than physically involved activities (33%) due to maintain social distancing. Besides about 46% maid was suspended due to hygienic concern and 45% driver was suspended because of the inability of maintenance cost i.e. an economic pressure which has been reflected on all classes of people. According to life scale assessment, 35% people were slightly dissatisfied and only 1% of them are extremely satisfied during this situation. It means that maximum of the people allows their living condition to be in the less satisfied range during this pandemic situation. Besides, hospital accessibility has been analyzed among the lockdown wards and it is observed that ward no.-24 whose has good accessibility with 292 m distance from the locality but poor condition has been observed in ward no.-17. To attenuate these ill socioeconomic conditions, initiatives of inclusive cooperation of different stakeholders should be taken spontaneously.
