针对非道路用车辆的排放法规要求,研究人员正重新审视发动机设计,并为零部件引入最新的技术和定制排气后处理系统。降低颗粒排放是影响发动机整体性能和价格的关键问题之一。目前,业界还没有一种统一的解决办法。部分制造商采用高压燃油喷射与高效的柴油氧化催化转化器组合的方式,而另一些制造商则依靠主动再生柴油机排气颗粒过滤器技术或单用选择性催化还原技术来达到欧盟第4阶段和关国第4f阶段排放标准。考虑到上述方法的利弊,VM Motori公司决定采用一种新技术,将柴油氧化催化转化器与分流式颗粒过滤器(PM-Metalit(?))用于新型R750发动机系列。讨论这种方法的优点,同时介绍为达到排放限值所进行的应用性研究。介绍PM-Metalit(?)技术无须维护保养就可降低颗粒排放的物理及化学机理。此外,还将讨论模拟实际运行条件得出的试验结果。

The aim of the investigations presented here was to understand how the stiffness of the adhesive affects the failure of ceramic tiles adhered to metallic backings. The working hypothesis was that varying the adhesive stiffness could have the same effect on the ballistic performance as a variation of the adhesive *** different projectile/target combinations were utilized for ballistic tests in order to generate extremely different loading conditions. With targets consisting of 6 mm aluminum oxide ceramic and 6 mm aluminum backing, complete penetration occurred in each test with 7.62 mm tungsten carbide core AP ammunition at an impact velocity of 940 m/s. In contrast, with ceramic tiles of 20 mm thickness on 13 mm steel backing,no penetration of the ceramic occurred at the impact of a 7.62 mm ball round at 840 m/*** different types of adhesive(high-strength till high-flexible) were tested in both configurations. The elongation of the adhesive layer, the deformation of the metallic backing and the failure of the ceramics were observed by means of a high-speed camera during the projectile/target *** results of the ballistic tests showed that a higher fracture strain caused a larger deformation of the backing compared to adhesives, which exhibit a high tensile strength and low fracture *** experimental results indicate that the damage behavior of the ceramic/metal composites depends on the absolute elongation of the adhesive layer. This can be controlled either by the thickness or the stiffness of the bonding layer.

AIM: To assess the extent and reasons of non- compliance in surveillance for patients undergoing polypectomy of large (≥ 1 cm) colorectal adenomas. METHODs: Between 1995 and 2002, colorectal adenomas ≥ 1 cm were diagnosed in 210 patients and subsequently documented at the Erlangen Registry of Colorectal Polyps. One hundred and fi fty-eight patients (75.2%) could be contacted by telephone and agreed to be interviewed. Additionally, records were obtained from the treating physicians. REsULTs: Fifty-four out of 158 patients (34.2%) neglected any surveillance. Reasons for non-compliance included lack of knowledge concerning surveillance intervals (45.8%), no symptoms (29.2%), fear of examination (18.8%) or old age/severe illness (6.3%). In a multivariate analysis, the factors including female gender (P = 0.036) and age > 62 years (P = 0.016) proved to be signif icantly associated with non-compliance in surveillance. CONCLUsION: Efforts to increase compliance in surveillance are of utmost importance. This applies particularly to women’s compliance. Effective strategies for avoiding metachronous colorectal adenoma and cancer should focus on both the improvement in awareness and knowledge of patients and information about physicians for surveillance.

Background： Bacillus spp. seem to be an alternative to antimicrobial growth promoters for improving animals＇ health and performance. However, there is little information on the effect of Bacillus spp. in combination with different dietary crude protein（CP） levels on the ileal digestibility and microbiota composition. Therefore, the objective of this study was to determine the effect of Bacillus spp. supplementation to low-（LP） and high-protein diets（HP） on ileal CP and amino acid（AA） digestibility and intestinal microbiota ***： Eight ileally cannulated pigs with an initial body weight of 28.5 kg were randomly allocated to a rowcolumn design with 8 pigs and 3 periods of 16 d each. The assay diets were based on wheat-barley-soybean meal with two protein levels： LP（14% CP, as-fed） and HP diet（18% CP, as-fed）. The LP and HP diets were supplemented with or without Bacil us spp. at a level of 0.04%（as-fed）. The apparent ileal digestibility（AID） and standardized ileal digestibility（sID） of CP and AA was determined. Bacterial community composition from ileal digesta was analyzed by Illumina amplicon sequencing and quantitative real-time PCR. Data were analyzed as a 2 × 2 factorial design using the GLIMMIX procedures of ***： The supplementation with Bacillus spp. did not affect both AID and sID of CP and AA in growing ***, there was no difference in AID of CP and AA between HP and LP diets, but sID of cystine, glutamic acid,glycine, and proline was lower（P 〈 0.05） in pigs fed the HP diets. The HP diets increased abundance of Bifidobacterium spp. and Lactobacillus spp.,（P 〈 0.05） and by amplicon sequencing the latter was identified as predominant genus in microbiota from HP with Bacillus spp., whereas dietary supplementation of Bacillus spp. increased（P 〈 0.05） abundance of Roseburia ***： The HP diet increased abundance of Lactobacillus spp. and Bifidobacterium spp.. The supplementation of Bacil us spp. resulted in a higher abunda

要研究中国的宏观经济,首先需要确定适用于中国的经济增长模型和总量生产函数,但这方面研究迄今还很欠缺。该文运用基于数据生成过程的检验方法,研究经济增长的模型选择问题。结果表明:中国宏观经济具有两大特征:资本边际生产率非递减、投资率具有增长效应;所以,AK类型的经济增长模型适用于中国经济。对生产函数的检验结果显示,劳动力、教育年限和显性人力资本不能解释经济增长,只有物资资本和隐性人力资本可以解释经济增长;引进人力资本后进一步证明了这一结论。

Background: To validate a predictive scoring system for 1-year mortality among psychogeriatric inpatients admitted for acute psychiatric care. Methods: Computerized data were extracted from the District Health Board Database for a university affiliated general hospital. A geriatric risk scoring system developed in the UsA was employed to validate mortality within 1-year of hospital discharge. Results: Among 125 psychogeriatric inpatients who were discharged in 2017, [mean age 82.8 (±8.9) years, 82 (65.6%) women] 33 died within 1-year [26.4% of the sample, mean age, 87.7 (±11.1) years, 25 (75.7%) women]. Levine’s mortality index predicted death. A post hoc probit analysis found two factors significantly associated with predicted mortality: metastatic cancer (Chi-square = 5.6;p Conclusions: A geriatric 1-year mortality scoring system accurately predicted mortality among psychogeriatric inpatients. Predicting psychogeriatric mortality should be considered a guideline for ensuring quality of care and appropriate discharge and advanced care planning.
