杨明权"仙桃"送给众乡亲

现年56岁的杨明权是一个精明的苗族汉子。1981年,具有高中文化的他被贵州省兴义市顶效镇绿化村群众推选为村民委主任。当时该村水、电、路"三不通",人均吃粮仅135斤,人均纯收入仅82元,生活贫困。杨明权上任后,经过市场调查,选择了带领群众走种桃致富的路子。他自己垫资6000元,到关岭县请来技术专家作指导,并请市农业局技术干部到村里对全体民兵、青年团员、妇女进行技术培训,提高他们的种桃技能。     

维稳排头兵田景勇

贵州省兴义市桔山镇桔园村退伍军人、市民兵应急营二排排长田景勇今年29岁,退伍后他凭着良好的军政素质和一股实干巧干的精神,在村里拉起一帮年轻人搞起了建筑,走上了创业之路。一年下来,挣了不少钱,但他眷恋军营、心系国防的痴情不改。群众认为他是个能人,于是推选他当村委会主任,自然成了村民兵连长,挑起了带领群众走致富路和负责民兵工作的担子。市民兵应急营成立后,他被任命为二排排长。     

邯郸市在小学校开展“英雄中队”创建活动

自2001年以来,河北省邯郸市先后有200多所小学校创建了“英雄中队”。即以英雄人物名字和革命圣地地名命名少先队中队,旨在从小就帮助他们树立正确的人生观、价值观、国防观,打牢爱党、爱国、爱军、爱社会主义的思想基础。他们以“英雄中队”为单位,邀请英雄(先进)人物及其有关人员介绍英雄(先进)人物的事迹和传授我党我军的光荣传统,并通过黑板报、手抄报、故事会等形式,

A platform for initial testing of multiple camouflage patterns

The human visual system is still an important factor in military warfare; military personnel receive training on effective search strategies, and camouflage that can effectively conceal objects and personnel is a key component of a successful integrated survivability strategy. Previous methods of camouflage assessment have, amongst others, used psychophysics to generate distinctiveness metrics. However, the population from which the human observers are drawn is often not well defined, or necessarily appropriate. In this experiment we designed a new platform for testing multiple patterns based on a camouflaged object detection task, and investigate whether trained military observers perform better than civilians. We use a two-alternative forced choice paradigm, with participants searching images of woodland for a replica military helmet displaying Olive Green, Multi Terrain Pattern, US Marine Pattern or, as a conspicuous control, UN Peacekeeper Blue. Our data show that there is no difference in detection performance between the two observer groups but that there are clear differences in the effectiveness of the different helmet colour patterns in a temperate woodland environment. We conclude that when tasks involve very short stimulus presentation times, task-specific training has little effect on the success of target detection and thus this paradigm is particularly suitable for robust estimates of camouflage efficacy.     

Field test and probabilistic analysis of irregular steel debris casualty risks from a person-borne improvised explosive device

Person-borne improvised explosive devices (PBIEDs) are often used in terrorist attacks in Western countries. This study aims to predict the trajectories of PBIED fragments and the subsequent safety risks for people exposed to this hazard. An explosive field test with a typical PBIED composed of a plastic explosive charge and steel nut enhancements was performed to record initial fragment behaviour, including positions, velocity, and trajectory angles. These data were used to predict the full trajectory of PBIED fragments using a probabilistic analysis. In the probabilistic analyses a probability of fatality or serious injury was computed. Based on the results presented, many practical conclusions can be drawn, for instance, regarding safe evacuation distances if a person were exposed to a suspected PBIED.     

Improvement of VIS and IR camouflage properties by impregnating cotton fabric with PVB/IF-WS2

In order to examine the possibility to improve its camouflage properties standard cotton fabric with camouflage print was impregnated with poly(vinyl butyral), PVB and fullerene-like nanoparticles of tungsten disulfide, PVB/IF-WS₂. FTIR analysis excluded any possible chemical interaction of IF-WS₂ with PVB and the fabric. The camouflage behavior of the impregnated fabric has been examined firstly in the VIS part of the spectrum. Diffuse reflection, specular gloss and color coordinates were measured for three different shades (black, brown and dark green). Thermal imaging was applied to examine the camouflage abilities of this impregnation in IR part of the spectrum. The obtained results show that PVB/IF-WS₂ impregnation system induced enhacement of the materials camouflage properties, i.e. that IF-WS₂ have a positive effect on spectrophotometric characteristics of the fabric.
