THE QUANTUM-CHEMICAL INVESTIGATION OF INTERMOLECULAR INTERACTIONS IN COMPLEX SYSTEMS «POLYAMIDE-SILICA GEL»

The paper presents the results of quantum-chemical studies of polymer composite materials based on aromatic polyamide phenylon C1 filled with silica gel. Structural models of initial compounds with indication of charges on atoms and interatomic distances are offered. The theoretical models of complexes in «polyamide-silica gel» systems have been constructed, which describe the most probable intermolecular interactions of the polymer matrix with the filler. The adequacy of the obtained models was confirmed by the results of IR spectroscopy. It has been found that the chemical interaction of polymer molecules with the filler is carried out mainly due to the formation of strong hydrogen bonds that occur between oxygen atoms of carbonyl groups in polymer molecules and active hydroxyl groups on the surface of silica gel particles. The chemical nature for intermolecular interactions of polymer with filler has also been confirmed with preliminary physico-mechanical and thermophysical studies of polymer composite materials, as a result of which it was found, that the introduction of fine silica gel particles into the structure of phenylon C1 contributes to a significant increase of the level of stress at the yield strength, modulus of elasticity in compression and hardness with a shift of the corresponding values of heat and heat resistance of the obtained polymer composites in the area of higher temperatures.
Note Integer Factoring Methods III

The best deterministic unconditionally proven integer factorization algorithms have exponential running time complexities of O(N^(1/4)) arithmetic operations, and conditional on the Riemann hypothesis, there is a deterministic algorithm of exponential running time complexity O(N^(1/5)). This note proposes a new deterministic integer factorization algorithm of deterministic exponential time complexity O(N^(1/6)). Furthermore, an algorithm for decomposing composite integers that have factor differences of the form q - p = (r - 1)N^(1/2) + u, where r > 1 is a fixed parameter, and | u | < N^(1/3), in deterministic logarithmic time and various other results are included.
Sulfate-activating Enzymes of Penicillium chrysogenum

At a noninhibitory steady state concentration of adenosine 5‘-phosphosulfate (APS), increasing the concentration of Penicillium chrysogenum ATP sulfurylase drives the rate of the APS kinase-catalyzed reaction toward zero. The result indicates that the ATP sulfurylase . APS complex does not serve as a substrate for APS kinase, i.e. there is no “substrate channeling” of APS between the two sulfate-activating enzymes. APS kinase had no effect on the [S]o.6 values, nH values, or maximum isotope trapping in the single turnover of ATP sulfurylase-bound [36S]APS. Equimolar APS kinase (2MgATP or APS) also had no effect on the rate constants for the inactivation of ATP sulfurylase by phenylglyoxal, diethylpyrocarbonate, or N-ethylmaleimide. Similarly, ATP sulfurylase (kligands) had no effect on the inactivation of equimolar APS kinase by trinitrobenzene sulfonate, diethylpyrocarbonate, or heat. (The last promotes the dissociation of dimeric APS kinase to inactive monomers.) ATP sulfurylase also had no effect on the reassociation of APS kinase subunits at low temperature. The cumulative results suggest that the two sulfate activating enzymes do not associate to form a “3’-phosphoadenosine 5’-phosphosulfate synthetase” complex.

Family Integration Could Potentially Improve the Integrated Care and Management of Childhood Chronic Problems in Developing Countries Primary Care Epidemiology and Global Health

Integrated Care and Abstract Malaria, pneumonia and diarrhoea have together caused most childhood deaths particularly in resource poor underserved areas, though they are preventable and curable. The Integrated Community Case Management strategy building on previous child survival programs has been adopted to improve access to treatment of children at risk of these diseases. Despite its gains in some areas however, the neglect of the role of households is a major constrain in achieving its full potentials. The integration of the households in the iCCM would importantly make family members responsive and responsible to healthcare decisions and provisions, if they are properly empowered. The effect of this would be the appropriate recognition and distinguishing of childhood illnesses at home, prompt and appropriate management at home, prompt and appropriate self-referral attitude as well as awareness and demand of appropriate services at formal and informal points of care. Furthermore, it will offer a source for generating and maintaining reliable data on childhood illness events.
Repositioning Conflicting Partners Under Inventory Risks

This paper investigates dynamic differentiation strategies under inventory risks when manufacturers open a direct channel to compete with their partner retailer. Differentiation is often employed in conflicting channels, but effectiveness becomes unclear when inventory risks are present. Accordingly, we propose that given the inventory risks and cost under demand variability, various coordinated strategies can be achieved through product repositioning with proper pricing. We find that forbearance strategy should be proposed to the manufacturer, to focus on potential market demand if the product in a direct channel is cheaper than and inferior to the product in an indirect channel. The direct channel should adopt assistance strategy if the product in a direct channel is more expensive than and inferior to the product in an indirect channel. For products with high demand variability (e.g., luxury goods) and high selling cost, a high price should also be set for low-positioned products. Moreover, the differentiation should be high for direct and retail channels.
Improving the Power Quality in Tehran Metro Line-Two Using the Ant Colony Algorithm

This research aims to survey the improvement of power quality in Tehran metro line 2 using the ant colony algorithm and to investigate all the factors affecting the achievement of this goal. In order to put Tehran on the road of sustainable development, finding a solution for dealing with air pollution is essential. The use of public transportation, especially metro, is one of the ways to achieve this goal. Since the highest share of pollutants in Tehran belongs to cars and mobile sources, relative statistical indicators are estimated through assuming the effect of metro lines development and subsequently reduction of traffic on power quality index.
Aspects of locally covariant quantum field theory

This thesis considers various aspects of locally covariant quantum field theory (LCQFT; see Brunetti et al., Commun.Math.Phys. 237 (2003), 31-68), a mathematical framework to describe axiomatic quantum field theories in curved spacetimes. New results include: a philosophical interpretation of certain aspects of this framework in terms of modal logic; a proof that the truncated n-point functions of any Hadamard state of the free real scalar field are smooth, except for n=2; a description of he free Dirac field in a representation independent way, showing that the theory is determined entirely by the relations between the adjoint map, the charge conjugation map and the Dirac operator; a proof that the relative Cauchy evolution of the free Dirac field is related to its stress-energy-momentum tensor in the same way as for the free real scalar field (cf. loc.cit.); several results on the Reeh-Schlieder property in LCQFT, including but not limited to those of our earlier paper; a new and elegant approach to wave front sets of Banach space-valued distributions, which allows easy proofs and extensions of results in the literature.
Wind Turbines from the Swedish Wind Energy Program and the Subsequent Commercialization Attempts – A Historical Review

This paper summarizes wind turbines of Swedish origin, 50 kW and above. Both the large governmental-funded prototypes from the early 1980s and following attempts to build commercial turbines are covered. After the 1973 oil crisis, a development program for wind turbine technology was initiated in Sweden, culminating in the early 1980s with the 2 and 3-MW machines at Maglarp and Näsudden. However, government interest declined, and Sweden soon lost its position as one of the leading countries regarding wind turbine development. Nevertheless, several attempts to build commercial wind turbines in Sweden were made in the following decades. Most attempts have, like the earlier prototypes, used a two-bladed rotor, which has become synonymous with the Swedish wind turbine development line. The current ongoing Swedish endeavors primarily focus on the niche-concept of vertical axis wind turbines (VAWTs), which is a demonstration of how far from the broad commercial market of Sweden has moved. Thus far, none of the Swedish attempts have been commercially successful, and unlike countries like Denmark or Germany, Sweden currently has no large wind turbine producer. Suggested reasons include early government interventions focusing on two-bladed prototypes and political disinterest, with wind power grants cut in half by 1985, and the domestic industry not being favored in government policies for deploying wind power.
A Framework Utilizing Augmented Reality to Enhance the Teaching–Learning Experience of Linear Control Systems

In recent years, engineering education has become more complex, more uncertain and more interdisciplinary. It is therefore important to supplement the theoretical introduction of technical topics and concepts with practical, learning by doing experiences, so as to maximize the learning outcome. When introduced to challenging technical concepts and topics through conventional diagrams and equations, such as those found in textbooks, many students have difficulty with visualization; limiting their ability to gain a deep understanding of the concept. The computer visualization (using Virtual Reality or Augmented Reality (AR)) has apparently become a problem-solving tool in engineering education. AR can overlay 3D virtual objects to a particular real-world context and is an effective way to enhance the visualization and as a result, the understanding of technical concepts. One topic commonly challenging for students to understand is the stability analysis of linear time-invariant control systems. To address this, this paper introduces the framework of a tabletop AR learning environment based on the tangible user interface (TUI) and consisting of a fixed VGA camera with a display screen.
STORAGE AND RELEASE OF MAGNETIC ENERGY IN A FORCE-FREE FIELD J.J. ALY Service d1Astrophysique Centre dfEtudes

For a 3D force-free field occupying a half-space D = {z > 0}, we discuss : i) the storage of free magnetic energy when the field evolves quasi-statically as a consequence of motions imposed to its footpoints on the plane {z = 0} ; ii) the release of this energy during a reconnection process implying a rearrangement of the lines which is either local, occuring in the neighbourhood of spontaneously formed current sheets, or global, occuring in an explosive flare-like way.
IJBF IS ISLAMIC BANKING CAPABLE OF MEETING CORPORATE SOCIAL RESPONSIBILITY?

This paper provides an overview of the Islamic banking system and its product ranges, and examines their ability to meet Corporate Social Responsibility obligations while maintaining efficiency and managing risk. The growing literature on Islamic banking products, including their derivatives indicates that Islamic banking is popular worldwide and has global attention. Similarly, the diversity of banking options is growing in Middle Eastern countries with some banks offering separate windows for conventional and Islamic banking options to customers. Due to the unique nature of Islamic banking, which is constrained not only by the standard operating regulations of the respective countries, but also by Islamic law, the Sharī’ah, there are significant differences in the philosophy behind its finance transactions, the nature of transactions, goals and the obligations between the two types of institutions. Whether these differences lead to changes in risk preferences, lending decision-making processes, and the ultimate efficiency of operations are some of the key empirical questions yet to be fully answered. The paper introduces a theory based on classical utility theory, and then extends it to show its relevance to Islamic banking. In particular this paper shows that Islamic banking may not only improve operating performance, but also increase profitability for all parties concerned.
An Introduction to Stochastic PDEs

These notes are based on a series of lectures given first at the University of Warwick in spring 2008 and then at the Courant Institute in spring 2009. It is an attempt to give a reasonably self-contained presentation of the basic theory of stochastic partial differential equations, taking for granted basic measure theory, functional analysis and probability theory, but nothing else. The approach taken in these notes is to focus on semilinear parabolic problems driven by additive noise. These can be treated as stochastic evolution equations in some infinite-dimensional Banach or Hilbert space that usually have nice regularising properties and they already form a very rich class of problems with many interesting properties. Furthermore, this class of problems has the advantage of allowing to completely pass under silence many subtle problems arising from stochastic integration in infinite-dimensional spaces.
Metabolism and Disposition of 3-Amino-1,5-dihydro-5-methyl-1-#-D- ribofuranosyl-1,4,5,6,8-pentaazaacenaphthylene in thÃ ̈Rat1

Tricyclic nucleoside (TCN, NSC 154020) is a 7-deazapurine nucleoside possessing antitumor activity towards certain tumor cell lines in vitro. In vivo, TCN is readily interconvertible with its 5'-monophosphate ester. The present study demonstrates that TCN is metabolized by rat liver microsomes to a ring-opened bicyclic metabolite with loss of cytotoxicity toward Chinese ham ster ovary cells in culture. Metabolism is mediated by hydrogen peroxide generated by the rat liver microsomes but is not de pendent on cytochrome P-450. Isolated hepatocytes prepared from rat do not form detectable amounts of the ring-opened bicyclic metabolite. Unchanged TCN and the ring-opened bicyclic metabolite are excreted in the bile of rats with a cannulated bile duct, comprising 42 and 12% of an i.v. dose of TCN in 8 hr, respectively. The ring-opened bicyclic metabolite is not formed by red blood cells in vitro and could not be detected in blood in vivo. The fact that the ring-opened bicyclic metabolite appears in bile suggests that liver cells not present or not active in isolated hepatocyte preparations might produce the metabolite. Alterna tively, the metabolite might be formed directly from TCN in bile, perhaps by hydrogen peroxide excreted into bile. In vivo, 56% of radiolabel was found in the upper and lower gastrointestinal tract and the feces 24 hr after an i.p. or i.v. dose of 100 mg of [5-mef/jy/-14C]TCN/sq m. Urinary excretion of radiolabel was 21% of the dose of [14C]TCN in 24 hr. Biliary excretion of radiolabel was 65% of the dose of [14C]TCN in 8 hr. The fraction of radioactivity undergoing enterohepatic cycling with reabsorption from the gastrointestinal tract after excretion in bile is 84%.
Decomposltlon of Storm Generated Lltter ln a Troptcal Foothtll Raln Forest , West Sumatra

An equatorial rain forest in West Sumatra suffered defoliation and severe stem damages from two storms in early 1995. Intensity of litter production at a storm generated gap site was 2? 5 ton h*1, and big woody debris over 10 cm in diameter accounted for 78Vo. A mass of fine litter promptly lost its weight of dry matter in Ao layer directly after the event, and the rate tended to have a positive correlation to the initial amount of accumulation. An impact of these mass litter production on a material cycling of an equatorial rain forest ecosystem was simulated basing on these field data and monitoring data of a forest since 1981, The simulation showed that fine litter would supply nutrients enough for revegetation at an initial stage in particular, and a great amount of woody debris would contribute to the process at later stages because of their low decomposition rate. The time needed for 95% loss of initial litter amount by decomposition at a gap site was estimated at 11 years in this forest irrespective of amount, when the composition of litter is same. This average decay rate overcomes a net primary productivity. From a carbon balance between both potential rates of decay and growth for initial 11 years after a damage, it shows that about 10O (organic matter) ton ha-1 of litter production is a boundary value between its sink and source for this stand.

ATIYAH'S L 2 -INDEX THEOREM

The $L^2$-Index Theorem of Atiyah \cite{atiyah} expresses the index of an elliptic operator on a closed manifold $M$ in terms of the $G$-equivariant index of some regular covering $\widetilde{M}$ of $M$, with $G$ the group of covering transformations. Atiyah's proof is analytic in nature. Our proof is algebraic and involves an embedding of a given group into an acyclic one, together with naturality properties of the indices.
A dual‐band antenna for extending cellular coverage by using energy‐harvesting strategy

The widespread use of sensor nodes forces a straightforward, low‐cost, and easy‐to‐implement design of these nodes. Instead of using separate batteries and antennas, this letter proposes a dual‐band microstrip antenna for both communication and energy‐harvesting applications. The energy required for the sensor node is harvested from the broadcast television band and then used in the cellular phone communication band. A previous design of a circular polarized broadband patch antenna is adapted and optimized for the defined requirements with the electromagnetic simulation software CST Studio Suite. The simulations helped in an antenna design with a reflection coefficient below −10 dB in the 600 MHz ‐ 700 MHz television frequency band for the energy harvesting. Furthermore, the antenna is also able to operate in the 850 MHz cellular mobile phone communication band, in order to provide coverage in shadowed remote areas or even to be of use for the transmission of the sensor data. The final design is prototyped and then characterized through the measurement of the reflection coefficient.
initio study of gallium like Molybdenum and Tungsten

Possibilities of the new quasirelativistic approach designed for ab initio calculations of spectral characteristics of highly charged ions and heavy atoms are briefly described and illustrated with an example of a study of spectral characteristics of gallium-like Molybdenum and Tungsten. 1. Brief description of the method Within the quasirelativistic approach the main relativistic effects are taken into account already in obtaining the radial orbitals. Nevertheless the orbitals remain one component and independent on j. Some peculiarities of the well-known quasirelativistic approximation by R. D. Cowan, described in the monograph [1] and references therein, caused a demand of creating this different approach. The general form of the quasirelativistic Hartree-Fock (QRHF) equations used by us is described in [2]. Taking into account the corrections for p electrons presented in paper [3] brings about the quasirelativistic equations of the following form: ( )
Travel behaviour and health: a conceptual model and research agenda

Objectives. This paper proposes a conceptual model of the complex relationships between travel behaviour and health. In addition it gives a research agenda providing an overview of challenges for future research. Methods. We review the relevant literature in the areas of public health, land use and transportation that address issues related to health and travel and their underlying mechanisms. We do not aim to give a full review of the literature but to underpin the conceptual model. Results and conclusions. We conclude that research can easily come to the ‘wrong’ conclusions if the complex causal relationships that exist between relevant factors are overlooked. In particular, ignoring contradictory effects for specific socio-demographic groups, (residential) self-selection effects, substitutions of different forms of activity, and reverse causalities may lead to overestimation of the effect of policies. For example, travel-related physical activity might interact with other physical activity, self-selection effects may influence the complex relationships between travel behaviour and health, and people’s health may influence their walking or cycling behaviour. Based on the conceptual model we present a research agenda. A first research challenge is to explore the combined effect of travel behaviour related determinants for health effects (physical activity, air pollution intake, injuries, and subjective well-being) on health. A second challenge is exploring the interactions between travel-related physical activity and other physical activity. Thirdly, the importance of attitudes and attitude formation, specifically health-related attitudes and selfselection processes related to travel behaviour, is an important research topic. Fourthly, it is important to explore the relationship between cycling levels and injury risks, because risks seem to be correlated with cycling levels: the more people cycle, the lower the injury risks. Fifthly, we think it is important to study the relevance of walking and cycling related self-selection effects. A sixth challenge relates to transport innovations.
