Characteristics of Competitive Baton Twirling Athletes

Competitive baton twirling is a sport that combines elements of gymnastics, dance and ballet while necessitating cardiovascular endurance, muscular endurance and power, hand-eye coordination, spatial awareness, kinesthetic awareness, timing and choreography. Approximately one million baton twirlers participating in the sport in the United States. Despite considerable participation in competitive baton twirling, little is known about the characteristics of the athletes. This work documents demographic and behavioral characteristics of competitive baton twirlers. Questionnaires were completed by 169 female twirlers from across the Unites States and Canada. Respondents reported a mean (± SD) age of 18.07 yrs. (±6.08) and height of 63.89 in (±6.24), weight 133.56 lbs. (±32.49), BMI (22.92), GPA 3.73 (±0.31), years of competing 8.02 yrs. (±1.81). All (100%) qualified respondents reported experiencing injury due to competing in or training for baton. The extent of the injuries reported varied greatly. A diversity of training, recovery, hydration, and nutrition habits were also reported. These findings indicate that the competitive baton twirlers that participated in this research are adolescent females, diverse in physical profile, of normal BMI, high academic achievers, dedicated athletes, consistently overcome injuries and train by diverse means. Future research may consider the long-term physical effects and an association with mental health competitive baton twirling has on the athletes.

Ion dynamics driven by a strongly nonlinear plasma wake

In plasma wakefield accelerators, the wave excited in the plasma eventually breaks and leaves behind slowly changing fields and currents that perturb the ion density background. We study this process numerically using the example of a FACET experiment where the wave is excited by an electron bunch in the bubble regime in a radially bounded plasma. Four physical effects underlie the dynamics of ions: (1) attraction of ions toward the axis by the fields of the driver and the wave, resulting in formation of a density peak, (2) generation of ion-acoustic solitons following the decay of the density peak, (3) positive plasma charging after wave breaking, leading to acceleration of some ions in the radial direction, and (4) plasma pinching by the current generated during the wavebreaking. Interplay of these effects result in formation of various radial density profiles, which are difficult to produce in any other way.

OPERATING CONDITIONS OF SPACE CHIPS

The issues of creating modern microelectronics for special purposes and the conditions of its operation are considered. The trends in the development of space-purpose microcircuits and their influence on radiation resistance are determined. The paper presents the main physical phenomena that dominate among the radiation effects in recent years. Reducing the characteristic sizes of VLSI elements leads to the appearance of new physical effects, for which it is necessary to develop new models, or improve existing ones.

ENERGY EFFICIENT IMPROVEMENT OF HISTORIC BUILDINGS: A CASE STUDY IN SINOP

Although historical buildings are ecological with their construction systems and materials, they cannot provide necessary performance in today's comfort conditions and therefore they are abandoned and remain in a damaged or dysfunctional state. Energy efficient improvement works are carried out in historical buildings in order to bring the historical buildings today's conditions, re-use and ensure their sustainability. However, there are many limitations in these studies due to the heritage characteristics of historical buildings. With these limitations, the works to be done should be carried out with the least intervention without damaging the heritage values of the historical buildings. For this reason, it is necessary to specially select the applications to be realized within the scope of energy efficiency in historical buildings and scaling the physical effects of the applications relative to each other. In this context, in this study, it is aimed to reveal the appropriate improvement methods in order to reach the maximum energy efficiency with the least physical intervention, with the techniques suitable for the historical texture by preserving the original qualities in the historical buildings. Based on the Historic England intervention evaluation scale developed in this framework, 5 scenarios, including the current situation and 4 different design scenarios, including interventions from small to large impacts, were created on a sample historical residential building, and the data of each scenario in terms of energy consumption were obtained. Models created within the framework of the scenarios were evaluated with the Design Builder simulation program, and annual heating and cooling loads and the amount of energy consumed per total m² were obtained. Evaluations were made by comparing the energy efficiency of applications at different degrees with the graphics and tables prepared in the light of these data. As a result, suggestions have been developed regarding the interventions to be made to historical buildings according to the intervention effect sizes in the context of energy efficiency with the evaluations made.

Mathematical modeling of water purification in a bioplato filter

A mathematical model of filtration taking into account clogging and suffusion in the bioplato filter system in the two-dimensional case was built. The constructed mathematical model takes into account the physical effects of the dynamic change of porosity and the dependence of the filtration coefficient on the concentration of contaminants, which is not in the known analogues

Organisational Identity and Alcohol Use in Knowledge-Intensive Workplaces

<p>The use of alcohol is an integral social act in many cultures and societies. The reasons for its use, as well as its mental and physical effects on people, have been a topic of academic interest for decades. This thesis examines the relationship between the work lives of individuals and their use of alcohol. At a more specific level, the thesis examines the relationship between alcohol use and the concept of organisational identity. Using data collected from interviews with members of a knowledge-intensive workplace, findings are presented that illustrate how alcohol use can be understood as an important part of processes of organisational identification, and how workers' alcohol use can be affected by an organisation's identity itself. The theoretical implications of these findings are numerous. Firstly, these findings suggest that organisational concepts, such as organisational identity, can be exceptionally useful in gaining an understanding of the reasons why individuals use alcohol in the ways that they do. In addition, the findings suggest that knowledge-intensive workplaces represent a valuable site for further advancing understandings of the work-alcohol relationship. Finally, it is argued that alcohol use in many situations should be understood as a part of individuals' organisational life, and not just a product or outcome of their participation in an organisation.</p>
