在一台改制的发动机上进行了异辛烷、乙醇及其混合燃料HCCI燃烧的研究。发动机性能用缸内压力评估,研究用的参数包括放热率、平均指示压力和热效率。试验结果表明,乙醇着火时刻早于异辛烷;在乙醇中加入异辛烷可以推迟着火,并导致平均指示压力和热效率的降低;对某种特定燃料,HCCI燃烧的发生主要取决于进气充量温度,初始充量温度的增加将导致HCCI燃烧提前;充量温度低或发动机转速低时,混合气形成质量差,对HCCI燃烧有不良影响;指示热效率为30%~43%,其值高于火花点火发动机;预燃室的存在有利于稳定的HCCI燃烧;超稀充量运行可以显著降低NOx排放。

Our perception of biodiversity in the geological past is incomplete and biased because most organisms did not have mineralized skeletons and therefore had little chance of fossilization. This especially refers to shallow- water marine environments, rarely represented by localities with exceptional preservation of fossil material （known as taphonomic windows or Konservat-Lagerstaitten）. Such extraordinary “windows” may markedly broaden our knowledge of biodiversity of the past. Here, we show a review of the invertebrate fossils from recently discovered locality in the Lower Ordovician Fenxiang Formation of Hubei Province in southern China revealing exceptional preservation of soft tissues. The fauna, generally of shal- low-water aspect, contains linguloid brachiopods with a remarkably preserved pedicle, the oldest traces of nema- tode life activities, the oldest reliable record of hydroids, the first fossil antipatharian corals, a pyritized colonial organism of unknown affinity, supposed arthropod ap- pendages, probable phosphatized scalidophoran worm embryo and other fossils. Our discovery supports the opinion that the famous soft-bodied preservation of Bur- gess Shale- or Chengjiang-type did not vanish from the fossil record in post-Cambrian times. The new finding represents a prelude to the Great Ordovician Biodiversifi- cation Event and provides evidence for calibration of molecular clock of several invertebrate lineages.

Background: Immune stress induced by lipopolysaccharide(LPS) influences the gonadotropin-releasing hormone(GnRH)/luteinizing hormone(LH) secretion. Presence of LPS interacting Toll-like receptor(TLR) 4 in the hypothalamus may enable the direct action of LPS on the GnRH/LH secretion. So, the aim of the study was to investigate the influence of intracerebroventricular(icv) injection of TLR4 antagonist on GnRH/LH secretion in anestrous ewes during LPS-induced central inflammation. Animals were divided into three groups icv-treated with: Ringer-Locke solution, LPS and TLR4 antagonist followed by ***: It was demonstrated that TLR4 antagonist reduced LPS-dependent suppression of GnRH gene expression in the preoptic area and in the medial basal hypothalamus, and suppression of receptor for GnRH gene expression in the anterior pituitary gland. It was also shown that TLR4 antagonist reduced suppression of LH release caused by icv injection of LPS. Central administration of LPS stimulated TLR4 gene expression in the medial basal ***: It was indicated that blockade of TLR4 prevents the inhibitory effect of centrally acting LPS on the GnRH/LH secretion. This suggests that some negative effects of bacterial infection on the hypothalamic-pituitary-gonadal axis activity at the hypothalamic level may be caused by central action of LPS acting through TLR4.

AIM To investigate the impact of IL28 B and OAS gene polymorphisms on interferon treatment responses in children with chronic hepatitis *** We enrolled 52 children(between the ages of 4 and 18) with hepatitis B e antigen-negative chronic hepatitis B(CHB), who were treated with pegylated interferon alfa for 48 wk. Single nucleotide polymorphisms in the OAS1(rs1131476), OAS2(rs1293747),OAS3(rs2072136), OASL(rs10849829) and IL28B(rs12979860, rs12980275 and rs8099917) genes were studied to examine their associations with responses to IFN treatment in paediatric patients. We adopted two criteria for the therapeutic response, achieving an hepatitis B virus(HBV) DNA level < 2000 IU/m L and normalization of ALT activity(< 40 IU/L). To perform the analyses, we compared the patients in terms of achieving a partial response(PR) and a complete response(CR) upon measurement at the 24-wk posttreatment follow-up. RESULTS The PR and CR rates were 80.8% and 42.3%, respectively. Factors such as age, gender and liver histology had no impact on the type of response(partial or complete). A statistically significant relationship between higher baseline HBV DNA and ALT activity levels and lower rates of PR and CR was shown(P < 0.05). The allele association analysis revealed that only the IL-28 B rs12979860(C vs T) and IL28 B rs12980275(A vs G) markers significantly affected the achievement of PR(P = 0.021, OR = 3.3, 95%CI: 1.2-9.2 and P = 0.014, OR = 3.7, 95%CI: 1.3-10.1, respectively). However, in the genotype analysis, only IL-28 B rs12980275 was significantly associated with PR(AA vs AG-GG, P = 0.014, OR = 10.9, 95%CI: 1.3-93.9). The association analysis for CR showed that the TT genotype of IL28 B rs12979860 was present only in the no-CR group(P = 0.033) and the AA genotype of OASL rs10849829 was significantly more frequent in the noCR group(P = 0.044, OR = 0.26, 95%CI: 0.07-0.88). The haplotype analysis revealed significant associations between PR and CR and OAS haplotype(P = 0

Solving complex problems by multi-agent systems in distributed environments requires new approximate reasoning methods based on new computing paradigms. One such recently emerging computing paradigm is Granular Computing(GC). We discuss the Rough-Granular Computing(RGC) approach to modeling of computations in complex adaptive systems and multiagent systems as well as for approximate reasoning about the behavior of such systems. The RGC methods have been successfully applied for solving complex problems in areas such as identification of objects or behavioral patterns by autonomous systems, web mining, and sensor fusion.

AIM: To compare the results of in vivo human high resolution image registration studies of the eye during accommodation to the predictions of mathematical and finite element models of accommodation. METHODS: Data from published high quality image registration studies of pilocarpine induced accommodative changes of equatorial lens radius(ELR) and central lens thickness(CLT) were statistically analyzed. RESULTS: The mean changes in ELR and CLT were 6.76 μm/diopter and 6.51 μm/diopter, respectively. The linear regressions, reflecting the association between ELR and accommodative amplitude(AAELR) was: slope=6.58 μm/diopter, r^2=0.98, P<0.0001 and between CLT and AACLT was: slope=6.75 μm/diopter, r^2=0.83, P<0.001. On the basis of these relationships, the CLT slope and the AAELR were used to predict the measured change in ELR(ELRpredicted). There was no statistical difference between ELRpredicted and the measured ELR as demonstrated by a Student's paired t-test: P=0.96 and linear regression analysis: slope=0.97, r^2=0.98, P<***: Image registration with invariant positional references demonstrates that ELR and CLT equivalently minimally increase ~7.0 μm/diopter during accommodation. The small equivalent increases in ELRand CLT are associated with a large accommodative amplitude. These findings are consistent with the predictions of mathematical and finite element models that specified the stiffness of the lens nucleus is the same or greater than the lens cortex and that accommodation involves a small force(<5 g).

The present paper analyses the possibilities of using modern technology and technical engineering in conservation practices. Some examples of heritage abuse are given alongside some innovative ways of presenting relics of the past to society. Methodology consists in the scrutinizing of chosen examples, selecting conclusions and a synthetic presentation of research results. The aim is proper protection of historic architectural resources through documentation and dissemination of knowledge. First part is concerned to rejection of old aesthetics values and implementing a new one on example of Brussels＇ House of the People （the largest work by Victor Horta that opened on 1899 and demolished in 1965 despite a protest of architects） and ridiculous renovation in Krynica, Poland. In second part, it presents tree examples of successful implementation of innovative techniques and technologies as the Pauline fathers realizations of renovation sacred architecture （churches, cloisters）, also valuable digital projects of the reconstruction of the vaults and realization of underground Museum in Krakow, Poland （the outstanding creation of the atmosphere of virtual historic reality by the latest audio-visual techniques）.
