Gunshot injuries are always known to cause severe morbidity and mortality when head and neck are involved. They vary in morbidity, which can occur in civilian surroundings. The wound largely depends on the type of weapon, mass and velocity of the bullet, and the distance from where it has been shot. Close-range gunshot wounds in the head and neck region can result in devastating aesthetic and functional impairment. The complexity in facial skeletal anatomy cause multiple medical and surgical challenges to an operating surgeon, demanding elaborate soft and hard tissue reconstruction. Here we presented the successful management of three patients shot by short-range pistol with basic life support measures, wound management, reconstruction and rehabilitation.

(接上期)3关于溶胶-凝胶合成反应动力学和不同影响因素的初步探讨众所周知,在溶胶-凝胶反应的水解和缩合阶段,催化剂起到非常重要的作用。在酸性和碱性催化体系作用下,硅醇盐发生水解反应的机理如图9所示,从图中的反应机理可以看到,过渡态的稳定性对于水解过程的反应速率至关重要,此外,过渡态的稳定性还与-OH和-OR基团的吸电子和供电子特性密切相关,通常碱性条件下的水解速度比酸性条件的水解速度更快。

Genotyping by sequencing(GBS) is the recent approach of next-generation sequencing technique for discovering and genotyping single nucleotide polymorphisms(SNPs) in crop species. Genotypic variation studies(SNPs and insertion-deletions/In Dels) were performed using four rice lines based on GBS data by aligning to the reference genome Nipponbare. Local aromatic rice landrace Tulaipanji was crossed with Ranjit, and two distinct lines were identified from the progenies: one line with awns and aroma traits and the other without awns and aroma. Total number of SNPs and In Dels identified were 52 810 and 4 327 at read depth 10, respectively. Out of the total polymorphic SNPs/In Dels, 16 490 were intergeneric, 7 812 were inside gene, and 4 435 were intronic. Phylogenetically, Tulaipanji was closer to the reference genome nipponbare. Based on recurrent parent genome analysis, out of 10 013 alleles, 92.52% was introgressed into progeny-awn from Tulaipanji and 7.48% from Ranjit, whereas progeny-awnless carried 89.19% alleles from Ranjit and only 10.81% alleles from Tulaipanji. In addition, progeny-awn was the highest heterozygous(83.88%) and progeny-awnless was the least(2.24%) at this fifth generation of recombinant inbred lines. These SNP variations may be linked to the phenotypic traits and can be utilized in crop improvement through linkage mapping. These results suggest that adding a high density of SNP markers to a mapping or breeding population through GBS has a great value for numerous applications in rice breeding and genetics research.

This paper provides a comprehensive review of the recent development on the switched reluctance machine operating in generating mode in both the low and high speed operations. The machine consists of a salient rotor and stator poles and controlled via switching of the power electronic devices. There is a steady development of the machine operating in the motoring mode;however, its generating operation is still under study. This paper gives an overview of the machine, followed by the principle of operation in generating mode and briefly discusses the structure and types of control methods which involve the switched reluctance generator (SRG). Due to its geometry simplicity and advantages such as robust, ability to operate over a wide speed range and absence of permanent magnet and windings on the rotor, the SRG promises to be a good candidate for variable speed application.

Three gram negative bacteria isolated from infected koi carp, Cyprinus carpio L. and screened for sensitivity to thirty antibiotics by the Bauer disc diffusion method. Bacteria evaluated were Aeromonas hydrophila, Pseudomonas aeruginosa and Edwardseilla tarda. A. hydrophila was resistant to ampicilin, cephalothin, sulphatriad, cefpodoxime and cefoxitin. Highest sensitivity was recorded to Colistin methane sulphonate and Ceftriaxone. High resistance was observed for P. aeruginosa in Kanamysin, Cephalothin, Sulphatriad, Colistin methane sulphonate, Tobramysin, Nitro Furantoin, Cefpodoxime, Cefoxitin and Aztreonam. Highest sensitivity recorded with Moxifloxacin. High resistance was observed in Co-trimoxamole and higher sensitivity performed for E. tarda by Tetracyclin, Cephotaxime, Ciprofloxacin, Norfloxacin, Ofloxacin, Moxifloxacin, Gatifloxacin and Levofloxacin. Out of that highest sensitivity recorded with Moxifloxacin High sensitivity was recorded for Moxifloxacin, Ciprofloxacin, Gatifloxacin, Levofloxacin. By means of antibiotic sensitivity test highest resistance was recorded to P. aeruginosa （MAR index-0.3） and least resistant was recorded to E, tarda （MAR index- 0.033）.

Benzil bis(carbohydrazone)(BBC) is prepared and explored as new N N Schiff's base, which plays the role of an excellent ion carrier in the construction of a Cd(II) ion membrane sensor. The tris(2-ethylhexyl) phosphate best performance corresponds to a membrane composition of 30% poly(vinyl chloride), 65%(TEHP), 3.5% BBC and 1.5% tetradodecyl-ammoniumtetrakis(4-chlorophenyl) borate(ETH 500). This sensor shows very good selectivity and sensitivity towards cadmium ion over a wide variety of cations, including alkali, alkaline earth, transition and heavy metal ions. The effect of membrane composition, selectivity, pH and influence of additive on the response properties of electrode were investigated. The response mechanism was discussed in the view of UV-spectroscopy. The electrode exhibits a Nernstian behavior(with slope of 29.7 mV per decade) over a very wide concentration range from 1.0×10?1 to 1.0×10?8 mol·L?1 with a detection limit of 3.2×10?8 mol·L?1. It shows rela-tively fast response time in whole concentration range(<8 s) and can be used for at least 10 weeks in the pH range of 2.0-9.0. The proposed sensor is successfully used for the determination of cadmium in different chocolate sam-ples and as indicator electrode in titration with ethylene diamine tetraacetate(EDTA).
