Manifestation of rheological properties of bituminous binders over a wide a range of temperature in real life pavements can be attributed to various factors viz. crude source, processing methods, oxidative aging and chemical composition. A clear understanding of the fundamental chemical and rheological properties of bitumen and their interrelationship is important to address issues related to b...

Performance (such as a course grade) is a joint function of an individual's ability (such as intelligence) and the situation (such as the instructor's grading leniency). Prior research has documented a human bias toward dispositional inference, which ascribes performance to individual ability, even when it is better explained through situational influences on performance. It is hypothesized her...

Virtual Private Networks (VPNs) offer an alternative solution using Internet Protocol (IP) tunnels to create secure, encrypted communication between geographically distant networks using a common shared medium such as the Internet. They use tunneling to establish end-to-end connectivity. OpenVPN is a cross-platform, secure, highly configurable VPN solution. Security in OpenVPN is handled by the...

Because economic value of carcasses is dependent primarily on carcass weight and carcass quality, feedlot managers have an interest in factors associated with maximizing these two variables. The NRC (1996) proposes that body composition (fat and protein) and carcass characteristics of beef cattle at a specified percentage of mature body weight (BW) are fixed, which indicates that maturity, rath...

The intent of this investigation was to examine the potential influence of varying durations of physical exertion at different times of the day on immediate mathematical performance by 120 sixth-grade boys and girls. Subjects were assigned to two control and two treatment groups (Solomon Four-group Design), with treated subjects administered physical exertion (paced walking at controlled modera...

This study investigated the relationship among blood pressure reactions to mental stress, cynical hostility, and socioeconomic status (SES) in 1,091 male public servants. Occupational grade served to index SES and cynical hostility was assessed using the Cook-Medley scale. (Cook & Medley, 1954). The magnitude of systolic, but not diastolic, blood pressure change scores to stress was positively ...

PURPOSE We investigated the associations of cardiovascular and motor performance in grade 1 with academic skills in grades 1-3. METHODS The participants were 6- to 8-yr-old children with complete data in grades 1-2 for 174 children and in grade 3 for 167 children. Maximal workload during exercise test was used as a measure of cardiovascular performance. The shuttle run test (SRT) time, the er...

Children with a mathematical learning disability (MLD, n = 19) and low achieving (LA, n = 43) children were identified using mathematics achievement scores below the 11th percentile and between the 11th and 25th percentiles, respectively. A control group of typically achieving (TA, n = 50) children was also identified. Number line and speed of processing tasks were administered in 1st and 2nd g...

The use of high performance liquid chromatography (HPLC) grade water is very important for laboratory studies, especially food quality control. These studies have a great impact on diagnosing food health. Food health improves the health of the community and these two parameters are closely related. HPLC grade water is ultra-pure water with low UV absorption ability. This water is often purified...

background & aim: the most common primary brain tumors of the central nervous system are gliomas. among a number of different biomolecular events, a strong relation between oxidative stress pathways and the development of this cancer has been proved. oxidative stress (os) is the consequence of an imbalance between pro-oxidants and antioxidants towards pro-oxidants. the pro-oxidants cause lipid ...
