DeGroot, David W., and W. Larry Kenney. Impaired defense of core temperature in aged humans during mild cold stress. Am J Physiol Regul Integr Comp Physiol 292: R103–R108, 2007. First published May 25, 2006; doi:10.1152/ajpregu.00074.2006.—Aged humans often exhibit an impaired defense of core temperature during cold stress. However, research documenting this response has typically used small su...

Sample-based scheduler design has become an emerging research topic for its high scalability and simple scheduling process in today’s big data cluster. One major limitation of such design is its lack of global cluster knowledge, which leads to sub-optimal decisions. Some cutting edge schedulers solve this issue by deploying an extra centralized component in the cluster to capture the real-time ...

The word forensic analysis conjures up images of Sherlock Holmes, or scientists adorned with lab-coats, hunched over corpses. But in this article, I will lead you through steps that you can take to analyse compromised computer systems. While forensics carries with it legal connotations, requirements for evidence collection, and analysis at a level unattainable by most system administrators, my ...

A 20-kDa protein (p20) that had internal amino acid sequences highly similar to those of aB crystallin was purified from rat and human skeletal muscle. p20 coeluted with (YB crystallin and HSP27/28 during column chromatography on DEAE-Sepharose and on Bio-Gel A-5m. p20 was separated from aB crystallin and HSP27/28 and was resolved into two fractions, a minor first peak and a major second peak,...

In this study, we suggest an efficient and useful method by using Chebyshev polynomials to approximate eigenvalues of a non-singular sixth-order Sturm-Liouville equation. This method uses Chebyshev polynomials and integration operation matrix for approximating of function and its derivatives. We convert the original problem for finding the eigenvalues of Sturm-Liouville problem to a problem of ...

abstract unlike the early years of 20th century, in which, most theories sought the roots of theatre in rituals, and based on this notion were busy analyzing for stage texts and on stage events, contemporary theories overview this phenomenon in relation with other performance genres such as play and their interactions. according to this fact, based-on-origin theories have lost their primary rep...

A cold sensitivity test (CST) is one of the assessments used to classify the level of non-freezing cold injury (NFCI) in patients presented to a cold injury clinic. The CST involves sitting in a chamber at 30°C for at least 30 min then immersing the injured site (usually a foot) in water at 15°C for 2 min. The NFCI classification is based on the skin temperature before and 5 min after immersion...

Changes in the skin temperature (Tsk) are known to be connected with diseases and subsequently infrared thermography (IRT) has been proposed to be a diagnostic aid, e.g. in musculoskeletal disorders (MSD). However, mostly due to conflicting results of previous studies, IRT lost credibility. Now interest in IRT is growing again but valid methodological studies are needed in order to avoid new di...

Personal protective equipment (PPE) markedly increases heat strain, reduces work performance, and increases the incidence of heat casualties. Microclimate cooling (MCC) technologies have been successfully used to alleviate this heat strain in mounted soldiers, but cooling limitations, power and weight restrictions do not currently make this technology applicable to dismounted soldiers. This com...
