Were Late Gomphotheres (Plio-Pleistocene) Of The Siwaliks At More Stress As Compared To Early Gomphotheres (Middle To Late Miocene)?, Muhammad Ameen, Abdul Majid Khan, Muhammad Tahir Waseem, Rana Manzoor Ahmad, Ayesha Iqbal, Amtur Rafeh, Muhammad Imran Dec 2020

Were Late Gomphotheres (Plio-Pleistocene) Of The Siwaliks At More Stress As Compared To Early Gomphotheres (Middle To Late Miocene)?, Muhammad Ameen, Abdul Majid Khan, Muhammad Tahir Waseem, Rana Manzoor Ahmad, Ayesha Iqbal, Amtur Rafeh, Muhammad Imran

Journal of Bioresource Management

Gomphotheres existed in the Siwaliks from the middle Miocene (14.2Ma) to the middle Pleistocene (0.8Ma) and became extinct later on. In this paper, we tried to discuss the reasons of such extinction of gomphotheres in the lower Pleistocene time span by considering Linear Enamel Hypoplasia (LEH) among 114 isolated tooth samples to assess whether ecological changes correlate with the stress factor in gomphotheres. For this purpose, the Siwalik gomphotheres were divided into two Groups viz. early gomphotheres (middle Miocene to late Miocene) and late gomphotheres (Pliocene to middle Pleistocene). We presented the hypothesis, that as the gomphotheres are characterized by …

The Effects Of Health-Based Wellness Programs On Employee Productivity, Brittany Holcomb

The Corinthian

Purpose: Stress is an inevitable part of an employee’s life. A majority of employees do not know how to properly handle stress and keep it under control. Having high level of occupational stress can lead to detrimental physical habits, such as poor nutrition, smoking, a sedentary lifestyle and substance consumption. The purpose of this study will be to take an in depth look into how employees take advantage of wellness programs offered to them, whether or not these programs have a direct impact on productivity and the levels of employees that take advantage the programs. Methods: Participants of the study …


The Effects Of Adolescent Chronic Mild Stress: In Female Wistar-Kyoto Rats, Anna Hallowell Aug 2020

The Effects Of Adolescent Chronic Mild Stress: In Female Wistar-Kyoto Rats, Anna Hallowell

The Journal of Purdue Undergraduate Research

Despite years of research to understand under-lying mechanisms and develop more effective treatment approaches for mood disorders, numerous challenges exist. Many chronic stress models are used to study mood disorders, how-ever the majority have been established with adult males. This is problematic considering that affective disorders are more common in women, and generally develop during late adolescence. Studies have indicated fundamental behavioral, physiological, and neural differences between males and females in response to the same external stressors, furthering a need to develop sex-specific paradigms to accurately model the etiology of mood disorders in females. The Wistar-Kyoto (WKY) rat strain is …


Esport: Fortnite Acutely Increases Heart Rate Of Young Men, Silvio Valladao, Jake Middleton, Thomas Andre Aug 2020

Esport: Fortnite Acutely Increases Heart Rate Of Young Men, Silvio Valladao, Jake Middleton, Thomas Andre

International Journal of Exercise Science

International Journal of Exercise Science 13(6): 1217-1227, 2020. Esports has rapidly increased in online play and viewing. A myriad of literature focuses on heart rate (HR) during traditional athletic competition, little research has addressed the HR responses of individuals playing esports and none in the esport: Fortnite. The purpose of this study was to compare the HR response during a 3-hour seated session of the esport: Fortnite to resting HR. Male college students (n = 23; age = 21 ± 1.8 years; BMI = 25.7 ± 3.9; Esport mean hours per week = 13 ± 8.7) were recruited to …

Effect Of Laboratory Heat Stress On Mortality And Web Mass Of The Common House Spider, Parasteatoda Tepidariorum (Koch 1841) (Araneae: Theridiidae), Aubrey J. Brown, David Houghton Feb 2020

Effect Of Laboratory Heat Stress On Mortality And Web Mass Of The Common House Spider, Parasteatoda Tepidariorum (Koch 1841) (Araneae: Theridiidae), Aubrey J. Brown, David Houghton

The Great Lakes Entomologist

We determined the effects of chronic heat stress on web construction of Parasteatoda tepidariorum (Araneae: Theridiidae) by measuring the survival and web mass of specimens after a 48-h period within a temperature chamber at 21, 30, 35, 40, or 50°C. The 21, 30 and 35°C treatments had the highest mean survival rate (100%), the 50°C treatment had the lowest (0%), and the 40°C treatment was intermediate (58%). The 21, 30, and 35°C treatments had the highest mean web mass, and the 40 and 50°C treatments had the lowest. Web mass did not correlate with spider mass for specimens across all …

Changes In Health Behaviors And Outcomes Following Graduation From Higher Education, Oliver W A Wilson, Peter J. Matthews, Michele Duffey, Zack Papalia, Melissa Bopp

International Journal of Exercise Science

International Journal of Exercise Science 13(5): 131-139, 2020. The purpose of this study was to examine changes in health behaviors and outcomes of higher education (college) students following graduation. Undergraduate students (n= 206) enrolled at a large, northeastern United States university in general education health and wellness courses were assessed pre and post-graduation. Participants self-reported their demographics, physical activity behaviors, dietary behaviors, sleep, and stress pre and post-graduation via an online survey. Paired sample t-tests examined changes health behaviors pre and post-graduation. Following graduation, fruit and vegetable consumption increased significantly, moderate physical activity declined significantly, and both vigorous …

Assessment Of Changes In The Saliva Cortisol Level Of Horses During Different Waysin Recreational Exploitation, Boguslawa Dlugosz, Tomasz Próchniak, Monika Stefaniuk-Szmukier, Marta Basiaga, Jaroslaw Luszczynski, Magdalena Pieszka

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to evaluate the saliva cortisol levelsof recreational horses dependent on the type of horse activity. A total of 68 horses were included in the experiment and divided into groups according to recreational activity, type of horse, age, term of saliva collection, and sex. Saliva samples were obtained from each horse at 3 measurement points: in the morning (6 a.m.), in the evening (6 p.m.), and immediately after work. The overall analysis shows that the term of sample collection, recreational activity, and age influence cortisol concentration. The diurnal concentration of saliva cortisol does not differ …
