Subjects (n=13) did 30 workouts with their left leg on an Inertial Exercise Trainer (IET), while their right leg served as an untreated control. Before and after the 30 workouts, they underwent isokinetic strength tests (knee and ankle extensors of both legs) whose peak torque (PT), time to PT (TTPT), and rate of torque development (RTD) values were each analyzed with 2(leg)×2(time)×3(velocity) analysis of variances (ANOVAs), with repeated measures per independent variable. Peak force (PF) and total work (TW) data were measured from each IET workout, and they represent time course strength changes produced by our exercise intervention. PF and TW values for the three IET exercises that comprised each workout were each analyzed with one-way ANOVAs with time as the independent variable. Results included significant ankle and knee extensor PT increases, whereby the left leg achieved higher values at posttesting, but there were no significant TTPT changes and a time effect for ankle extensor RTD. Our data show that PF and TW each had significant increases over time, with the latter exhibiting greater gains over the 30-workout intervention. Our results imply that the IET yields strength gains over time comparable to standard resistive exercise hardware.
Owing to the abundant forest resources, China is endowed with the advantages of developing forest ecotourism. In order that the forest resources better meet the demand of national tourism, the key is to explore the development condition and effect of forest ecotourism resources. Only with a development plan that accords with the national tourism demand can the economic value of forest ecotourism resources be realized to the greatest degree. In this study, we introduced the structural equation model which could be used to reflect the relationship and influence between variables. In the aspect of tourist satisfaction, we put forward an evaluation model for tourist satisfaction. Then, based on questionnaire surveys and in-depth interviews on the tourists from three scenic spots, we analyzed the development effect, quality of talents and support rates of the surrounding residents in the scenic areas. Furthermore, we established an influence mechanism model of the development effect of forest ecotourism resources, with resource factor, principal factor, market factor and macro factor as the influence factors. At last, we put forward countermeasures and suggestions for the optimization of resource development, which could provide policy suggestions for the development of national tourism.

Abrin is a highly toxic protein produced by Abrus precatorius. Exposure to abrin, either through accident or by act of terrorism, poses a significant risk to human health and safety. Abrin functions as a ribosome-inactivating protein by depurinating the 28S rRNA and inhibits protein synthesis. It is a potent toxin warfare agent. There are no antidotes available for abrin intoxication. Supportive care is the only option for treatment of abrin exposure. It is becoming increasingly important to develop countermeasures for abrin by developing pre- and post-exposure therapy. The aim of this study is to screen certain pharmaceutical compounds for their chemoprotective properties against abrin toxicity in vivo in BALB/c male mice. Twenty-one compounds having either antioxidant, anti-inflammatory and cyto-protective properties or combination of them, were screened and administered as 1h pre-treatment followed by exposure of lethal dose (2×LD50, intraperitoneally) of abrin. To assess the protective efficacy of the compounds, survival and body weight was monitored. Fifteen compounds extended the survival time of animals significantly, as compared to abrin. The following five of these compounds, namely: Epicatechin-3-gallate, Gallic Acid, Lipoic Acid, GSH and Indomethacin extended the life time ranging from 6 to 9 days. These compounds also attenuated the abrin induced inflammation and enzymes associated with liver function, but none of them could prevent abrin induced lethality. The compounds offering extension of life could be useful to provide a time-window for other supportive treatment and could also be used as combinatorial therapy with other medical countermeasures against abrin induced lethality.
Safety of Flying in the Air in Aspect of Using Electronic Warfare Device
The paper presents some problems of the safety of military air forces in the area of enemy air defence. Recently, this problem has become one of the most important issues of fighting against terrorists. Presented are some threats and techniques of fighting them. On the grounds of the threats analysis in the air defence areas, the author tries to predict safety condition in function of the quality and effectiveness of an onboard electronic warfare system.
NATO standardization documents are the basis for action in many areas of NATO military activity and their affiliated organizations. The development of the NATO standardization documentation has been on-going for more than 60 years, and their content provides a reliable basis for joint action in a unified manner, enabling interoperability in many areas of NATO operations. The article is divided into three parts, the first of which deals with the general principles of NATO standardization, the second part describes the standardization documents related to the measurement of the ship’s signatures in aspect of the mine countermeasures and the third describes the participation in research project of NATO — RIMPASSE 2011 Trial. One of the their task was to verify and update NATO standardization documents including AMP-15.
This paper involves fifty-one re-examinations of original polygraph tests that resulted in conflicted outcomes and examinations where deliberate distortions were believed to have been employed. The Polygraph Validation Test (PVT) was successfully employed in these re-examinations to rectify the original problems and/or confirm attempts by examinees at countermeasures or augmentations.
