High-speed steel W18Cr4V is commonly used in industries such as blade and mould manufacturers because of its high level of hardness and toughness, M-hardness and resistance, Ion implantation is an effective method to improve the wear resistance of W18Cr4V. In our investigation, Ta and Ta＋N ion implantation was performed on W18Cr4V high-speed steel. The surface properties after implantation were evaluated by measuring friction coefficients while the cabonyl phase of the surface was analyzed by X-ray diffraction analysis. It was found that the friction coefficients of the treated samples were much lower. Samples implanted with Ta＋N had a lower friction coefficients than samples implanted only with Ta. This can be attributed to the formation of a new chemical compound, Fe7Ta3, on both surfaces. An even harder chemical compound, FerN, was formed on both surfaces of Ta＋N implanted samples.

Language training for nonfluent aphasia （NFA） patients rmay increase their verbal expression of unfamiliarwords. Some therapies aimed at the improvement of cognitive functions can facilitate the recovery of NFA patients＇ damaged linguistic functions. Some studies have shown that with music cues NFA patients could fluently sing their familiar songs but could not read the lyrics, consistent with studies of proverbs and prayer） Our previous research has shown that highly related voice cues can improve NFA patients＇ verbal expression.2 These results indicate that the improvement of NFA patients＇ speech production may benefit from regaining the extraction of phonological encoding that has already been preserved in memory, rather than re-study of the language.

Background Chinese nonfluent aphasic patients experience apparent speech production deficit, but it remains less known in which part of Chinese speech production this deficit occurs. The present study aimed to examine the ability of nonfluent aphasic patients in Chinese orthography, phonological and semantic processing via two experiments. Experiment I disclosed the general pattern of deficit of Chinese nonfluent aphasic patients in speech production. Experiment II tested whether this deficit occurs in orthography, phonological or semantic processing. Methods The present study adopted neuropsychological testing methods to compare speech production and Chinese word processing between nonfluent aphasic patients （the patient group） and normal individuals （the control group）. Character reading and word reading tasks were used to test speech production. Chinese radical decision, rhyme decision and semantic decision tasks were used to examine word processing. Reaction time and the correct answer rate were collected. Results The patient group had a longer reaction time and was more prone to errors in both character reading and word reading tasks than was the control group. For the patient group, there was no difference between the reaction time of character reading and word reading, the error rate of the former was higher than the latter. In radical decision task the reaction time and error rate to the radical ＂木＂ were higher in the patient group than in the control group. In the rhyme decision task, the reaction time and error rate to the rhyme ＂ang＂ were higher for the aphasic patients. In the semantic decision task the reaction time to characters in the category of animals was higher for the aphasic patients, yet the error rate was not significantly different between the two groups. Conclusions Nonfluent aphasic patients seemingly have decreased speed of speech production and an increased error rate. There is a deficit in phonological processing of aphasic patients whil

Background Successful lung transplantation has been limited by the scarcity of donors. Brain death （BD） donors are major source of lung transplantation. Whereas BD process induces acute lung injury and aggravates lung ischemia reperfusion injury. Carbon monoxide （CO） inhalation at 50-500 parts per million （ppm） can ameliorate lung injury in several models. We examined in rats whether CO inhalation in BD donor would show favorable effects on lung grafts. Methods Rats were randomly divided into 4 groups. In sham group, donor rats received insertion of a balloon catheter into the cranial cavity, but the balloon was not inflated. In BD-only group, donor rats were ventilated with 40% oxygen after BD confirmation. In BD＋CO250 and BD＋CO500 groups, donor rats inhaled, after BD confirmation, 250 ppm or 500 ppm CO for 120 minutes prior to lung procurement, and orthotopic lung transplantation was performed. The rats were sacrificed 120 minutes after the lung transplantation by exsanguination, and their blood and lung graft samples were obtained. A total of 8 rats fulfilling the criteria were included in each group. Results The inhalation decreased the severity of lung injury in grafts from BD donors checked by histological examination. CO pretreatment reversed the aggravation of PaO2/FiO2 in recipients from BD donors. The CO inhalation down-regulated pro-inflammatory cytokines （TNF-α, IL-6） along with the increase of anti-inflammatory cytokine （IL-10） in recipient serum, and inhibited the activity of myeloperoxidase in grafts tissue. The inhalation significantly decreased cell apoptosis in lung grafts, inhibiting mRNA and protein expression of intercellular adhesion molecule-1 （ICAM-1） and caspase-3 in lung grafts. Further, the inhalation activated phosphorylation of p38 expression and inhibited phosphorylation of anti-extracellular signal-regulated kinase （ERK） expression in lung grafts. The effects of CO at 500 ppm were greater than those at 250 ppm. Conclusions CO exerts po

古村落旅游发展离不开游客的感知评价,探讨在古村落情境下的游客感知规律对古村落旅游可持续发展具有现实意义。基于游客感知价值及其维度视角,本文构建了古村落游客忠诚概念模型,并以湖南岳阳县张谷英村为例进行实证;通过探索性因子分析以及结构方程模型检验和修正,得到了古村落游客忠诚修正模型。修正模型表明,古村落游客感知价值作为单维度结构通过满意间接影响忠诚的形成,但其内在维度的忠诚机理差异明显,功能维的忠诚驱动显性化,情感维的忠诚驱动隐性化。研究认为,建立良好的古村落游客感知体验环境,创造和传递游客感知价值,可以培育游客对古村落的忠诚。
