Hybrid composite materials combine different fibers in preform and take advantages of different mechanical behaviors for improving ballistic impact damage *** we report ballistic impact damages of plain-woven laminates with different hybrids and stacking *** kinds of hybrid laminates,i.e.,carbon/Kevlar,carbon/ultra-high molecular weight polyethylene(UHMWPE),and UHMWPE/Kevlar,had been prepared and tested in ballistic penetration with fragment simulating projectiles(FSP).The residual velocities of the projectiles and impact damage morphologies of the laminates have been obtained to show impact energy absorptions for the different hybrid schemes.A microstructural model of the hybrid laminates had also been established to show impact damage mechanisms with finite element analysis(FEA).We found that the UHMWPE/Kevlar hybrid laminates with Kevlar layers as the front face have the highest energy absorption capacity,followed by the carbon/Kevlar hybrid laminates with carbon layers as the front *** main damage modes are fiber breakages,matrix crack and interlayer *** ballistic damage evolutions from the FEA results show that the major damage is shear failure for front layers,while tension failure for the back *** expect that the ballistic impact performance could be improved from the different hybrid schemes.

OBJECTIVE To investigate gene mutations of epidermal growth factor receptor （EGFR） and K-RAS （Kirsten rat sarcoma viral oncogene） in Chinese patients with non-small cell lung cancer （NSCLC）, and study the correlation with its protein expression and its clinical significance on *** Detect the EGFR and K-RAS gene mutations status by gene sequencing and use the method of immunohistochemistry to detect EGFR and K-RAS protein *** The frequency of EGFR mutations was 33%, mainly located in exon 19 and exon 21. The frequency of K-RAS mutations was 5.5%, mainly located in codon 12. There was no case which both had EGFR and K-RAS mutations, suggesting a mutually exclusive relationship between the two. EGFR mutations are more common in adenocarcinomas （particularly those with bronchioloalveolar features）, nonsmokers and females. 16% were detected EGFR positive expression and had no correlation with EGFR mutation （P 〉 0.05）, but had significant correlation with mutation in exon 19 （P 〈 0.05）. The frequency of K-RAS positive expression was 52.5% and had no correlation with K-RAS mutation （P 〉 0.05）. Twelve （8 cases were protein-negative） out of 15 gefitinib-treated NSCLC patients with disease control carry EGFR *** EGFR protein expression has some correlation with exon 19 mutations. Combined detection of EGFR and K-RAS gene mutations can help clinicians to choose patients who may benefit from EGFR tyrosine kinase inhibitor （EGFR-TKI） and to predict the response and prognosis of gefitinib.

By modulating the crystalline properties of the active layer with dual donors, the efficiency of organic solar cells reaches 19.23%.The introduction of PTzBI-dF suppresses the accumulation of traps and charge recombination, allowing ternary devices to maintain 82% of their initial power conversion efficiency (PCE) after illumination for 800 *** dual-donor strategy for modulating the crystallinity of the active layer is applicable to a variety of Y6 derivatives, and the increase in PCE exceeds 1%. Trap-assisted charge recombination is one of the primary limitations of restricting the performance of organic solar cells. However, effectively reducing the presence of traps in the photoactive layer remains challenging. Herein, wide bandgap polymer donor PTzBI-dF is demonstrated as an effective modulator for enhancing the crystallinity of the bulk heterojunction active layers composed of D18 derivatives blended with Y6, leading to dense and ordered molecular packings, and thus, improves photoluminescence quenching properties. As a result, the photovoltaic devices exhibit reduced trap-assisted charge recombination losses, achieving an optimized power conversion efficiency of over 19%. Besides the efficiency enhancement, the devices comprised of PTzBI-dF as a third component simultaneously attain decreased current leakage, improved charge carrier mobilities, and suppressed bimolecular charge recombination, leading to reduced energy losses. The advanced crystalline structures induced by PTzBI-dF and its characteristics, such as well-aligned energy level, and complementary absorption spectra, are ascribed to the promising performance improvements. Our findings suggest that donor phase engineering is a feasible approach to tuning the molecular packings in the active layer, providing guidelines for designing effective morphology modulators for high-performance organic solar cells.

In order to overcome the difficulty of extracting gold from gold-bearing sulfide ore by cyanide process flotation was adopted based on mineralogical analysis Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores. Primary gold-bearing sulfide ore is fine-grained pyrite and arsenopyrite. The paper describes the effects of ratios and dosage of activators and collectors on the recovery and grade of gold concentrate. A proper flotation flowsheet was then proposed based on experimental condition and closedcircuit test. The gold concentrate with the gold grade of25.14 g ton-1and the recovery of 86.94 % is obtained after one rougher, three cleaners, and four scavengers from fine grinding flotation process. Furthermore, the mechanisms of combined activators and combined collectors were studied by thermodynamic calculation, and structure-activity relationship of flotation reagent was also explained
