It provides the framework and accompanying guidelines for the evaluation and validation of the quality and effectiveness of the project outputs. Formative and summative evaluations of the different RAGE technologies and their underlying methodologies – the assets, the Ecosystem, and the applied games – will be carried out on the basis of this common framework.

On the algebraic K theory of the massive D8 and M9-branes

In this paper we review some basic relations of algebraic K theory and we formulate them in the language of D-branes. Then we study the relation between the D8-branes wrapped on an orientable, compact manifold W in a massive Type IIA, supergravity background and the M9-branes wrapped on a compact manifold Z in a massive d = 11 supergravity background from the K-theoretic point of view. By interpreting the D8-brane charges as elements of K-0(C(W)) and the (inequivalent classes of) spaces of gauge fields on the M9-branes as the elements of K-0(C(Z) x ((k) over bar*) G) where G is a one-dimensional compact group, a connection between charges and gauge fields is argued to exists. This connection could be realized as a composition map between the corresponding algebraic K theory groups.

JERICO Next. Rules and procedures for TNA. D8.9

The JERICO-NEXT Trans National Access (TNA) activity is built on the successful experience of the previous FP7 JERICO project, G.A. 262584 (Sparnocchia et al., 2014, 2016). However, it will involve a greater number of observatories distributed, as before, in coastal and shelf seas all around Europe, including some dedicated to biological observation (see D7.1 for a detailed description). A limited number of supporting facilities (calibration and research laboratories) and one item of special equipment are also included in the TNA service catalogue. This document relates to WP8 - Outreach, communication and engagement, and in particular to Task 8.8: Implementing Transnational Access to coastal observatories. It describes the procedures adopted for providing TNA during the three planned Calls for proposals, one per year from May 2016 until 2018. These procedures are a review and update of those already used by JERICO. Updates of this report prior to the next Call are possible and will depend on new needs that may emerge while conducting the first Call.

A phenomenological model for the structure-composition relationship of the high Tc cuprates based on simple chemical principles

A simple phenomenological model for the relationship between structure and composition of the high Tc cuprates is presented. The model is based on two simple crystal chemistry principles: unit cell doping and charge balance within unit cells. These principles are inspired by key experimental observations of how the materials accommodate large deviations from stoichiometry. Consistent explanations for significant HTSC properties can be explained without any additional assumptions while retaining valuable insight for geometric interpretation. Combining these two chemical principles with a review of Crystal Field Theory (CFT) or Ligand Field Theory (LFT), it becomes clear that the two oxidation states in the conduction planes (typically d8 and d9) belong to the most strongly divergent d-levels as a function of deformation from regular octahedral coordination. This observation offers a link to a range of coupling effects relating vibrations and spin waves through application of Hund’s rules. An indication of this model’s capacity to predict physical properties for HTSC is provided and will be elaborated in subsequent publications. Simple criteria for the relationship between structure and composition in HTSC systems may guide chemical syntheses within new material systems.

The taxation of international maritime leasing profits : has the commissioners ship come in?

In light of McDermott Industries (AUST) Pty Ltd v Commissioner of Taxation, and Draft Taxation Ruling TR 2006/D8, this article considers the current Australian taxation position of profits arising from the cross-border leasing of vessels in the maritime industry. It focuses on the tax treaties to which Australia is a party, in particular the application of the business profits provisions of those treaties, and the deemed existence of a permanent establishment where substantial equipment, owned by a fiscal non-resident, is used within Australian waters.

A Theoretical Investigation of the Ni(II)-Catalyzed Hydrovinylation of Styrene

We report a detailed and full computational investigation on the hydrovinylation reaction of styrene with the Ni(II)-phospholane catalytic system, which was originally presumed to proceed through a cationic mechanism involving a nickel hydride intermediate. The following general features emerge from this study on a specific catalyst complex that was found to give quantitative yield and moderate selectivity: (a) the activation barrier for the initiation (18.8 kcal/mol) is higher than that for the reaction due to a low-lying square-planar pentenyl chelate intermediate originating from a Ni(II)-allyl catalyst precursor. Consequently there is an induction period for the catalysis; (b) the exit of product from the catalyst is via a β-H-transfer step instead of the usual β-H elimination pathway, which has a very high activation energy due to a trans effect of the phospholane ligand; (c) the turnover-limiting and enantio- determining transition state is also the β-H-transfer; (d) because of the absence of a hydride intermediate, the unwanted isomerization of the product is prevented; (e) since the enantio-discrimination is decided at the H-transfer stage itself, the configuration of the product in a catalytic cycle influences the enantioselectivity in the subsequent cycle; (f) the trans effect of the sole strong ligand in the d8 square-planar Ni(II), the stability of the η3-benzyl intermediate, and the availability of three coordination sites enable regioselective hydrovinylation over the possible oligomerization/polymerization of the olefin substrates and linear hydrovinylation. This work has also confirmed the previously recognized role of the hemilabile group at various stages in the mechanism.

Electronic structure of high-Tc superconductors from core-level spectroscopies

Using the configuration-interaction approach, we show that various core-level spectroscopic observations on the high-Tc superconducting oxides can be consistently described in terms of mixing between d9 and d10 configurations, with a negligible amount of the d8 (Cu3+) state. From our analysis of the existing experimental data, we provide evidence of a wide and continuous valence transition in these systems as a function of temperature. The changes in the hybridization strengths deduced here are indicative of structural modifications of the square-planar CuO4 clusters with decreasing temperature.

结核分枝杆菌尼克酰胺酶/吡嗪酰胺酶的研究

本研究通过一系列生物学手段系统阐述了结核分枝杆菌尼克酰胺酶/吡嗪酰胺酶（PncA酶）的生物化学特征，并鉴定了酶当中的关键氨基酸。结果表明体外表达的结核分枝杆菌PncA酶是一个分子量为22.4 KDa的单体酶，其最适pH值和温度分别为6.6 ~ 7.4和35 ~ 45 °C。电感耦合等离子原子发射光谱结果表明PncA酶是一种含有Mn2+和Fe2+的蛋白，二者的比率为1:1。通过运用高效液相色谱和耦联氨酶试验的方法对纯化的PncA酶进行了动力学分析，结果表明PncA酶拥有相同的吡嗪酰胺酶和尼克酰胺酶活性。通过定点突变得到了9个突变，圆二色谱数据证明突变并没有引起PncA酶的二级结构的改变。对这9个突变的酶活性和金属离子含量分析的结果表明，D8、K96和C138是PncA酶结合和催化底物的关键氨基酸残基，D49、H51、H57和H71是金属离子结合的关键氨基酸，而Y103和S104则有可能与底物的结合稳定有关。我们的结果也表明，尽管与Pyrococcus horikoshii PncA酶的序列同源性很高，但二者在对金属离子的结合方式上存在明显差异, 并有可能导致两者在催化机制上的差异, 值得进一步研究。 通过筛选抗吡嗪酰胺药物的临床分离结核分枝杆菌19株，并对其pncA基因序列进行测序分析。结果再一次表明结核分枝杆菌PncA酶的突变与吡嗪酰胺耐药性密切相关，检测的准确性为78.9 %，并发现了一个在16位的甘氨酸突变为丝氨酸的新突变。

自养氨氧化混合种群特性和共存机理初步研究

组特殊自养氨氧化混合种群，表现：无机环境种群生长迅速、生物量高；在一个完全无机的自养生长环境中，不仅保持高氨氧化速率，并出现丰富的异养微生物种群；该种群置于异养、厌氧环境中，迅速表现出产氢特征。对于这样一个特殊的生态体系，研究其共生机理，以及联接这些种群之间的碳源和能源问题，将具有非常重要意义。我们拟从种群特征、细胞表面分泌产物、游离体系产物多糖、蛋白和脂肪酸方面开展研究。 第一部分，自养氨氧化混合种群的基本特征。采用氨氧化培养基，进行种群氨氧化特征研究；采用扫描电镜观察自养混合种群的微观特征；沉降、离心去除微生物种群，分析水相中的总有机碳、糖类等物质；利用LB培养基进行种群的分离、纯化，并采用DGGE手段对微生物种群结构进行分析。结果表明，接入菌种后（2/5000（V/V）），培养液中氨（200mg/L）在3－5天内快速降解；亚硝酸盐与氨氮变化呈负相关趋势，仅有少量硝酸盐含量（< 30mg/L）。氨氧化种群的生物量增长与氨氧化趋势一致，初始生物量7.75 mg/L(蛋白含量)，3-5天后生物量快速增长，并达到最高63.06 mg/L（蛋白含量）。电镜图片显示，种群外包裹一层粘液。离心除去菌体后，检测培养液总有机碳和糖的含量，同样表现出与生物量增长相似的特征，分别由初始的3.73、2.35 mg/L，3－5内天迅速增加，并分别达到最大值35.19、27.45 mg/L。经初步分离、纯化并对纯化菌株进行测序，获得了10株异养微生物分别为布鲁氏菌科苍白杆菌属、纤维单孢菌、类芽孢菌属、黄杆菌属、无色杆菌、鞘脂单胞菌、嗜麦芽寡养单胞菌、噬氢菌属、硫红球菌、假单胞菌；DGGE显示，约有20分条离带，我们对其中的两条优势条带进行切割回收测序，鉴定为欧洲亚硝化单胞菌（Nitrosomonas eur）。 第二部分：混合种群自养-异养菌共生的可能机制。在对微生物种群特征初步分析基础上，针对胞外糖类组分可能被微生物代谢分解，我们重点对微生物细胞蛋白质与糖类进行分析。采用超声结合RIPA裂解液裂解，SDS-PAGE电泳分析混合种群总蛋白种类，并通过氨基酸分析仪及红外光谱法分析氨基酸组成及蛋白红外特征。采用超声破碎结合反复冻融对细胞样品进行处理，提取液采用醇沉、Sevage脱氮白，凝胶过滤方法脱盐和分级分离。对提取物的糖分析包括：紫外扫描，红外光谱，核磁共振，单糖组成分析；扫描电镜观察菌群破裂现象。SDS-PAGE分析结果表明：氨氧化种群不同生长阶段都显示出42kD蛋白表达量很高，d4时42kD蛋白表达已经很强，4-7d内一直持续这种过量表达，直到d8后表达开始减弱。说明42kD蛋白可能与氨氧化密切相关。红外光谱分析显示：细胞提取物的特征峰分布在3427.42cm-1、1718.18 cm-1和1681.72 cm-1、1160.07和1086.74 cm-1，分别对应为OH、 C=O、C－O－C基团，表明具有蛋白的典型特征；氨基酸分析显示蛋白中的Gly,Asp,Ala,Glu含量相对较高。 提取物中胞外多糖分离谱图得到不均一组分，共得到6个收集峰；紫外扫描在201－213 nm处有多糖吸收峰，同样表明多糖成分不均一性；多糖红外光谱特征峰主要分别在3400.49 cm-1、2920.28 cm-1、1154.54和1087.52 cm-1，对应OH、－CH2－ or CH 、C－O－H or C－O－C等多糖特征基团；多糖提取物核磁共振1H d4.3～5.9之间出现强吸收峰，这是1H中，多糖存在的明显证据，1H NMR中，其中O-乙酰基的甲基上的氢信号为d1.1～1.3之间。糖肟全苯甲酸酯衍生物的HPLC测定中，得到单一的单糖峰，由于时间问题，还未进行更深入的试验；电镜图片显示，种群中的细胞有大量的破裂现象。 实验表明，自养氨氧化混合种群显示出快速的氨氧化速率，氨氧化过程生物量和有机质的增加明显。微生物种群包裹粘液层，并分离纯化出大量的异养菌；去除菌体后的游离培养液中存在有机质（包括多糖）说明无机自养生长体系中存在异养菌生长、繁殖的二次碳源；细胞提取物中蛋白条带数目多、种类丰富；细胞多糖提取物具有明显的多糖特征，以及单糖的存在。结合种群的显微特征和游离体系中的有机质的检测结果，我们认为，无机自养生长体系中，种群细胞生长过程中发生的破裂现象可能是导致大量的蛋白、多糖释放到游离胞外，并成为其他异养菌生长的碳源和氮源。这可能是自养体系中，大量异养菌共生的可能机制，至于是什么原因引起种群生长过程中产生的破裂现象，还有待下一步深入研究。 A group of mixed autotrophic ammonia oxidizing populations, having much biological characteristic tested by concerned personnel for pilot test: Performed rapid population growth and obtained high biomass in inorganic environment; Not only maintained a high rate of ammoxidation, promoted a wealth of heterotrophic microbial populations growth in a totally inorganic and autotrophic growth environment; Placed in heterotrophic and anaerobic environment,had the performance characteristics that could rapidly produce hydrogen.For such a special ecological system, Study its symbiotic mechanism and the connection between these populations of carbon and energy issues, will have a very important significance. We intended from the characteristics of the population, the secretion product of cell surface, free substance in the liquid medium like polysaccharide, protein and fatty acids carrying out research. Part I: The basic features of mixed autotrophic ammonia oxidizing populations . Use inorganic liquid medium, processed study for ammonia oxidation characteristics of the population; we used scanning electron microscopy to get micro-features of autotrophic ammonia oxidizing populations .The medium was carried out settlement and centrifugal then removed the microbial populations, after all of that we analysis the water phase for total organic carbon(TOC), carbohydrate and other substances; Solid ammonia oxidizing medium was adopted to separation and purification of population, DGGE means was for structure analysis of microbial population. The results showed that after the inoculum of bacteria (2 / 5000 (V / V)), ammonia in the culture medium (200 mg / L) was rapid degradation in 3-5 days; ammonia and nitrite have the negative correlation between changes in the trend, then only a small amount of nitrate content (<30mg / L). The biomass growth of ammoxidation population in line with the trend of ammonia oxidation, the initial volume of it was 7.75 mg / L (protein content), in 3-5 days upto 63.06 mg / L (protein content). Electron microscope image showed, the populations were wrapped in a layer of mucus, including the a large number ruptted micorbe , Centrifuge to remove bacteria, then detected the medium for total organic carbon and sugar content, result took on the same characteristics with biomass growth, that were from the initial 3.73、2.35 mg / L respectively, in 3-6 days achieved rapid increase in the maximum to 35.19、27.45 mg / L respectively. After initial separation、 purification ,then processed sequencing to strains purified and got the result that there were 10 heterotrophic microorganisms : Brucella Branch pale bacillus, Cellu lomonas, Bacillus species category, a Flavobacterium, colorless Bacteria, Aeromonas sheath fat, little support maltophilia Aeromonas, macrophages species hydrogen, sulphur-MI, Pseudomonas bacteria spores; DGGE display, there were 20 separation bands approximately. Part II: Mixed populations that autotrophic - heterotrophic bacteria symbiotic mechanism. On the basis of preliminary analysis of microbial population characteristics, aiming at extracellular carbohydrate components might be decomposition by microbial, we focused on microbial cell protein and carbohydrate analysis. Using ultrasound combined with RIPA lysis cracking the cells, SDS-PAGE electrophoresis analysis the total protein species of the population, and through the amino acid analyzer studied the compositions of amino acid and infrared spectroscopy analysis of a protein infrared characteristics. Using ultrasound combined with repeatedly freezing and thawing to treated the cell sample, then took the means that alcohol precipitation, deproteinization by Sevage, gel filtration aimed at desalination and grade separation to deal with the lysates . The extraction of sugar analysis included: UV scanning, IR, NMR, single-sugar composition analysis. SDS-PAGE analysis showed that: 42 kD protein expression was very high at different growth stages of mixed autotrophic ammonia oxidizing populations , on the fourth day, 42 kD protein expression had been very strong, 4-7d, it had continued this excessive expression, then started to weaken after 7 days. 42 kD protein that might be closely associated with ammonia oxidation. Infrared spectral analysis showed that: cell extracts with the characteristic that the peak distribution in 3427.42 cm-1、1718.18 cm-1 and 1681.72 cm-1、1160.07 cm-1 and 1086.74 cm-1 corresponding to OH、C = O、C-O-C Groups which had the typical characteristics of protein; and analysis showed that amino acids including Gly, Asp, Ala, Glu ,the content in the protein is relatively high. Exopolysaccharide in the extracts had the separation map that it was uneven, received a total of six collection peaks by the detection mode of phenol-sulphruic acid method ; ultraviolet scan in the 201-213 nm department had polysaccharide absorbing peak, the same ingredients that polysaccharide heterogeneity; infrared polysaccharide spectral characteristics of the main peak at 3400.49 cm-1, 2920.28 cm-1, 1154.54 and 1087.52 cm-1, corresponding OH,-CH2-or CH, C-O-H or C-O-C;and other characteristics of polysaccharide group; 1H NMR of polysaccharide extract appeared absorption peak between d4.3 ~5.9, which is the apparent evidence of polysaccharide, In 1H NMR, the hydrogen signal of one of O-acetyl was between 1.1 to 1.3. The determination of Sugar oxime whole benzoate derivatives by HPLC, there was a single-sugar peak, as a matter of time, yet more in-depth test. Summary: Mixed autotrophic ammonia oxidizing populations show us that it had the ability in ammonia oxidizing and it was great, organic matter and biomass increased significantly in the process of ammonia oxidation. Microbial populations was wrapped up slime layer, the phenomenon of cell breakdown obviously, and there were a lot of separation and purification of the heterotrophic bacteria; a lot of organic matter (including polysaccharides)remined in the medium that removal of cell indicated the inorganic system existed secondary carbon sources that could be used by the heterotrophic bacteria ; there were a large number proteins bands of cell extract, rich variety; cell extracts of polysaccharide had obvious characteristics of polysaccharide, and the existence evidence of single-sugar. Combined population of microscopic characteristics and free of organic matter in the test results, we believe that the health of inorganic system, population growth occurred in the course of the breakdown of the phenomenon is likely to lead to a lot of protein and polysaccharide released into the extracellular free, And other heterotrophic bacteria use them to the growth as carbon and nitrogen. This may be autotrophic system, the large number of heterotrophic bacteria symbiotic mechanism.

Characterizing evapotranspiration over a meadow ecosystem on the Qinghai-Tibetan Plateau

To characterize evapotranspiration (ET) over grasslands on the Qinghai-Tibetan Plateau, we examined ET and its relevant environmental variables in a Kobresia meadow from 2002 to 2004 using the eddy covariance method. The annual precipitation changed greatly, with 554, 706, and 666 mm a(-1) for the three consecutive calendar years. The annual ET varied correspondingly to the annual precipitation with 341, 407, and 426 mm a(-1). The annual ET was, however, constant at about 60% of the annual precipitation. About 85% annual ET occurred during the growing season from May to September, and the averaged ET for this period was 1.90, 2.23, and 2.22 mm/d, respectively for the three consecutive years. The averaged ET was, however, very low (< 0.40 mm/d) during the nongrowing season from October to April. The annual canopy conductance (gc) and the Priestley-Taylor coefficient (a) showed the lowest values in the year with the lowest precipitation. This study first demonstrates that the alpine meadow ecosystem is characterized by a low ratio of annual ET to precipitation and that the interannual variation of ET is determined by annual precipitation.

Measurement of oxygen storage capacity in automotive catalysts

There is considerable disagreement in the literature on available oxygen storage capacity, and on the reaction rates associated with the storage process, for three-way automotive catalysts. This paper seeks to address the issue of oxygen storage capacity in a clear and precise manner. The work described involved a detailed investigation of oxygen storage capacity in typical samples of automotive catalysts. The capacity has also been precisely defined and estimates have been made of the specific capacity based on catalyst dimensions. A purpose-built miniature catalyst test rig has been assembled to allow measurement of the capacity and the experimental procedure has been developed to ensure accurate measurement. The measurements from the first series of experiments have been compared with the theoretical calculations and good agreement is seen. A second series of experiments allowed the effect of temperature on oxygen storage capacity to be investigated. This work shows very clearly the large variation of the capacity with temperature.
