Proposed ballistic resistant article comprising a plurality of fibrous layers, each of said layers comprising a network of fibers and a matrix material, wherein the fibers have a strength of at least 800 mN in accordance with ASTM D7269-07 / Patent (1100 MPa), wherein the matrix material comprises - at least one self-crosslinking and or at least one crosslinkable acrylic resin and acrylic / resin - a mixture of at least one tackifier. However, as compared with products having a substrate having no tackifier having the same structure, article of the present invention comprises a high adhesion between the fiber layers and after immersion in water under low water absorption unaged and aged condition, and gasoline immersion test article passes. The article further comprising a metal plate or a ceramic exhibits minimal or even no fiber delamination of the layers, the article having the same structure but having a base body having no tackifier exhibits an internal fiber layer delamination after ballistic attack.


Dear Sir It was reported recently in Malaysia that four children between the ages of 3 to 4 years old died as a result of Enterovirus 71 (EV71) infection!. All four children showed evidences which implicated pulmonary edema as the main cause of death. In general, pulmonary edema or abnormal accumulation of extravascular fluid in the lung is a life-threatening condition which can occur as a result of myocardial infarction, cardiac dysfunction, left ventricle or mitral valve incompetence, allergic reactions and injuries to the central nervous system. In the later, it is postulated that significant damage to the vasomotor centre in the medulla as suggested in the above cases of EV71 infection could lead to neurogenic pulmonary edema. In these patients, however, the cellular pathopysiological changes in the lung were not described. Here, we present evidence derived from one of the child which suggests the potential involvement of apoptosis in pulmonary edema.


A distinguishing property of copper impurities in silicon is their very fast diffusivity, which is undesirable in silicon device processes. This paper is the first attempt to simulate the fast diffusion of Cu by first-principles calculations. It is shown that, even near room temperature, the amplitude of Cu vibrations is very large; this is a consequence of the fact that the local mode of Cu has very low frequencies. At T>1000 K, the simulations demonstrate clear migration between adjacent cells. The diffusion path is from an interstitial T site to the next T site through an H site. The Arrhenius plot of the calculated diffusion constants agrees with the experimental data on the intrinsic diffusion of Cu, which are currently most reliable data available.


This thesis based on the Agricultural research projects of Shanxi province (No: 20100311124) "Optimization of surface irrigation parameters of irrigation technology". In this study, the combined study methods of field experiment with theoretical analysis were adopted. Through the field infiltration tests of ten points within Wenyuhe Irrigation area, the characteristics of soil water infiltration and the various factors influencing soil water infiltration characteristics were studied systematic.
