Experimental and simulation optimization analysis of the Whipple shields against shaped charge

引用

Acta Mechanica Sinica 2012年第3期28卷 877-884页

Occasionally, the Whipple shields are used for the protection of a space station and a satellite against the meteoroids and orbital debris. In the Whipple shields each layer of the shield depletes part of high speed projectile en- ergy either by breaking the projectile or absorbing its energy. Similarly, this investigation uses the Whipple shields against the shaped charge to protect the light armour such as infantry fighting vehicles with a little modification in their design. The unsteady multiple interactions of shaped charge jet with the Whipple shield package against the steady homogeneous target is scrutinized to optimize the shield thickness. Sim- ulations indicate that the shield thickness of 0.75 mm offers an optimum configuration against the shaped charge. Exper- iments also support this evidence.

Effect　of　Ballistic-Type　Hot　Atom　Adsorption　Mechanism　on　the　Phase　Diagram　of　Monomer　Dimer　CO-O2　Surface　Catalytic　Reaction：　A　Monte　Carlo　Simulation

引用

Chinese Physics Letters 2004年第6期21卷 1171-1174页

作者： M.Khalid K.M.Khan A.U.qaisrani q.N.malik DepartmentofPhysics GomalUniversityDeraIsmailKhanPakistan NuclearPhysicsDivision PakistanInstituteofNuclearScienceandTechnology(PINSTECH)P.O.NiloreIslamabadPakistan

We investigate the effect of the ballistic mechanism on the phase diagram using a square surface. While using this mechanism whenever an O2 molecule hits a randomly vacant selected site, the molecule breaks up into atomic form and then executes a ballistic flight. The paths of the two oxygen atoms are taken exactly to be opposite to each other, ***-parallel, and the ranges of the atoms are taken to be equal, *** may fly up to 1 or 1.414 or 2 of the atomic spacing from the site of impact. Four cases have been studied on the basis of the range of hot atoms. The range of the hot oxygen atoms executing a ballistic flight might be up to the first nearest neighbourhood (1 atomic spacing from the site of impact), the second nearest neighbourhood (1.414 atomic spacing from the site of impact), the third nearest neighbourhood (2 atomic spacing from the site of impact), known as cases a, b, and c, respectively, while for case d the range of the oxygen atoms executing the ballistic flight might be up to 1 atomic spacing or 1.414 atomic spacing or 2 atomic spacing from the site of impact. The steady reactive window is observed and the continuous transition disappears. As soon as the CO partial pressure departs from zero, the production of CO2 is observed, which clearly verifies the experimental observation.

Photoluminescence and structural analysis of wurtzite(ZnO)1-x(V2O5)x composite

引用

Journal of Semiconductors 2018年第8期39卷 6-9页

作者： Amjid Iqbal Arshad Mahmood q. Raza A. Shah Rashad Rashid Zahid Ali A. malik U. Aziz National Institute of Laser and Optronics (NILOP) P.O. Nilore-45650 Islamabad Pakistan

This paper demonstrates the structural, vibrational and photoluminescence characteristics of(ZnO)(VO)(x = 0, 3, 6 and 9 mol%) composites semiconductor synthesized by using the solid state reaction method. X-ray diffraction(XRD) studies show that(ZnO)(VO)composites have the poly crystalline wurtzite structure of hexagonal Zn O. It is found from the XRD results that the lattice constants and the crystallite size increase while the dislocation density decreases with increase in doping concentration. The existence of E1(TO) and E2(high) Raman modes show that the Zn O still preserve wurtzite structure after doping vanadium oxide, which is in agreement with XRD results. Room temperature photoluminescence(PL) exhibit near band edge and broad deep level emission while indicating the suppression of deep level emission with the incorporation of VOup to a certain concentration(x < 9). Moreover, the optical band gap increase with doping, which is accompanied by the blue shift of the NBE emission.

OBJECTIVE： Helicobacter pylori is a Gram-negative organism. Its outer membrane protein q（Hop q） mediates host-pathogen interactions; Hop q genotypes 1 and 2 are found associating with gastroduodenal pathologies. The authors measured the anti-adhesion effects of the extracts of Abelmoschus esculentus, Zingiber officinale, Trachyspermum ammi, Glycyrrhiza glabra, Curcuma longa and Capsicum annum against Hop q genotypes and H. pylori cytotoxin-associated gene A（Cag A）.METHODS： DNA was extracted by polymerase chain reaction of the Hop q genotypes（i.e., type 1, type 2 and Cag A） from 115 H. pylori strains. The effect of the extracts from selected dietary ingredients was determined using a gastric adenocarcinoma cell line and a quantitative DNA fragmentation assay. The anti-adhesive effect of these extracts on H. pylori was tested using an anti-adhesion ***： C. annum, C. longa and A. esculentus showed prominent anti-adhesion effects with resultant values of 17.3% ± 2.9%, 14.6% ± 3.7%, 13.8% ± 3.6%, respectively, against Hop q type 1 and 13.1% ± 1.7%, 12.1% ± 2%, 11.1% ± 1.6%, respectively, against Hop q type 2. C. longa（93%）, C. annum（89%） and A. esculentus（75%） had better anti-adhesive activity against H. pylori with Hop q type 1 compared to Hop q type 2 with respective values of 70%, 64% and 51%. Extracts of C. annum（14.7% ± 4.1%）, A. esculentus（12.3% ± 4.1%） and Z. officinale（8.4% ± 2.8%） had an anti-adhesion effect against Cag A-positive H. pylori strains compared to Cag A-negative strains.
