This paper describes a new approach to solving the equations comprising the shrinking core model for diffusion and reaction of a chemical species in a solid spherical particle. The reactant adsorbs on the particle surface, diffuses into the particle`s interior, and reacts with the particle to form a solid product. The shrinking core model assumes a fast reaction rate compared to reactant diffusion so that the reaction is localized in the interfacial zone between the unreacted solid core and the surrounding shell of reacted product. Analytical solutions of the governing conservation equations usually invoke the pseudo-steady state (PSS) approximation which neglects the transient mass accumulation and diffusion-induced convection terms in the continuity equation for the diffusing reactant. However, small particle radii and slow reactant diffusion cast doubt on the validity of the PSS approximation. Dimensional analysis reveals an approximation that is less restrictive than PSS, yet enables a semi-analytical solution for the diffusing reactant distribution and interface velocity. For sufficiently large values of the surface mass fraction of the diffusing reactant, the PSS approximation leads to serious errors in the time dependence of the interface position and fractional conversion. However, the estimate of the surface mass fraction of hydrogen inmore » LaNi{sub 5} particles suggests the validity of the PSS approximation for hydriding of metal alloy particles. The shrinking core model thus enables an estimate of hydrogen diffusivity in metal alloy particles.« less


Tropical geomorphology is a relatively new and rapidly expanding area of study. Thus laterite has only recently been studied as the end-prod- uct of a specific tropical weathering process rather than as a pedological entity. The aim of this book is both to present existing informat-ion on the geomorphological aspects of laterite, and to broaden the environmental approach, encouraging geologists and geomorphologists to tackle an area of great practical importance for conservation in the Tropics. The author reviews the relationship between laterite genesis and landscape development, emphasizing the environment of formation — geology, topography, climate, vegetation and profile—and proposing a model associating laterite development with landsurface reduction.

Background: The occurrence of foreign bodies in air and food passages is an emerging problem both in adults & children. It has got a lot of significance as such accidents continue to take formidable toll of lives every year. To manage and prevent this critical problem an appropriate survey of cases is necessary. Hence this study is taken up to highlight age incidence, sex relation, type and site of foreign body, clinical features, radiological findings, complications and management strategies used in patients of foreign body ingestion and inhalation. Methods: A prospective clinical study of 50 cases of foreign bodies in aerodigestive tract was taken up over a period of one and half year. Careful history was taken from each patient. Appropriate examinations and radiological evaluation were performed. Details regarding age incidence of foreign bodies, sex relation, type and site of foreign bodies, clinical presentation, various investigations, modes of treatment given, post-operative complications were noted. Results: Most patients were children below 10 years of age, males being more common. Coins and peanuts are commonest foreign bodies observed. The most frequent site of lodgement of a foreign body in the food passage was cricopharynx (34%) while in the air passage it was nose. Radiological investigations and rigid endoscopy proved to be valuable. Associated complications vanned off after removal of foreign body. Conclusions: Early diagnosis, efficient and prompt treatment in all cases is mandatory, which will reduce the severity and number of complications drastically.

This paper introduces a new structure for stack filtering, where the filter adapts to the local characteristics encountered in data. Both supervised and unsupervised techniques for optimal design are investigated. We split the image into small regions and select the stack filter to process each region according to the spatial domain or threshold level domain characteristics of the input signal. This method provides a significant improvement potential over the global stack filtering approach. Some local statistics are computed, to build a reduced input space which efficiently describes the most important local characteristics of data. Vector quantization is used for clustering the reduced input space into a small number of regions, and then finding a mapping between reduced input space clusters and the filter space, will result in rules for selecting the best suited stack filter for a given region. The supervised clustering procedures are shown to surpass significantly the global filtering approach.


The presented gloss refers to Verdict, P88/08, issued on 10th November 2009 by the Constitutional Tribunal concerning the decision under Article 28 Section 1 of the Act of 28th February 2003 – Bankruptcy and Reorganisation Law [referred to as BRL] as regards the debtor who is not using a solicitor  or legal counsel, it indicates inconsistency of Article 28 Section 1 of the above Act with Article 45 of the Polish Constitution  and no inconsistency with Article 32 Section 1 of the Constitution. The Speaker of the Sejm, the Prosecutor General and the Research and Analysis Bureau have presented the position approving the compliance of Article 28 Section 1 of BRL with Article 32 Section 1 and Article 45 Section 1 of the Constitution. The Constitutional Tribunal draws attention to numerous formal requirements, especially concerning the bankruptcy petition filed by the debtor. The Tribunal states that the right to court may be infringed not only directly, but also indirectly as a result of the procedural requirements being formed by the legislator in the way making the initiation of the proceedings excessively difficult. Subsequently, the Tribunal points out that excessive strictness connected with considerable formalization of the bankruptcy petition does not perform the compensation function, and does not satisfactorily protect the debtor and his enterprise. In the context of professional representatives, the Tribunal expresses its position on the professional skills that assure  professional legal service in court proceedings. The Constitutional Tribunal made a distinction between debtors having a professional representative and debtors acting on their own, by defining a relevant feature that allows to separate a group, as a consequence the provision in question does not fulfil the constitutional requirements in Article 45 Section 1 of the Constitution. As regards Article 32 of the Constitution, the Constitutional Tribunal presents the view that with considerable complexity and strictness connected with the lack of representation, in a concrete case the constitutionally guaranteed rights may be infringed. As part of the verdict of the Constitutional Tribunal a separate statement was made in the part concerning the compliance of article 28 of BRL with Article 45 Section 1 of the Constitution. The present gloss shares the argumentation observed by the Constitutional Tribunal, at the same time paying attention to the public interest, negative results of the late submission of the bankruptcy petition, pointing to the legislator that greater protection of entrepreneurs debtors may be considered.

"My ideal, however is not to erase national characteristics in the manner leading towards intellectually uniform humanity. To the contrary, long live the variety of all forms and colors on our dear planet Earth. Beautiful is the existence of many races and peoples, multitude of languages, different mentalities and worldviews. If I feel the hostility and irreconcilable intolerance towards wars, conquering and annexations, it is caused by many reasons but mostly because of the fact that many organic, highly individual and sumptuous achievements of human civilization had been victim of those dark forces.

To identify the binding domain for dihydropyridine Ca2+ antagonists, skeletal muscle Ca2+ channels were photolabeled with [3HJ(+)-PN200-110 and [3H]azidopine. Regions of al photolabeled by these ligands were then identified by antibody mapping of proteolytic fragments. Approximately 50% of the specific labeling by both ligands was incorporated in domain m. [3H]Azidopine labeled peptide Gln-989-Arg1022, which contains a portion of the connecting loop between transmembrane segments HIIS5 and 11S6 (11S5/S6), and peptide Ala-1023-Lys-1077, which contains IIIS6 itself and some adjacent amino acid residues. In contrast, [3H](+)PN200-110 labeling occurred almost exclusively in the fragment containing m1S6. A second site labeled by both ligands was identified in transmembrane segment S6 of domain IV and adjacent residues. In contrast to azidopine, the photoreactive benzofurazane group of (+)-PN200-110 is located in close proximity to the essential dihydropyridine ring. Therefore, the regions photolabeled by [3H](+)-PN200-110 within or adjacent to transmembrane segments mS6 and IVS6 must participate in the formation of the dihydropyridine binding site. As IHS5/S6 is preferentially labeled by [3ll1azidopine, it may contribute to drug binding by interaction with the long side chain of some dihydropyridines like azidopine. It is proposed, based on physiological studies, that these three peptide segments interact to form a receptor site accessible from the extracellular surface of the Ca2+ channel. Voltage-gated L-type Ca2l channels can be distinguished from other types of Ca2" channels by their sensitivity to dihydropyridines (DHPs) and other organic Ca2"-channel modulators like phenylalkylamines and benzothiazepines (for review, see refs. 1 and 2). The binding sites for these drugs have been shown to be localized exclusively on the channel-forming al subunit ofthe Ca2+-channel complex (for review, see refs. 2 and 3). Due to its high abundance in skeletal muscle transverse tubules, voltage-gated L-type Ca2+ channels can be purified from this tissue with high yields (4,5). Using [N-methyl-3H]LU49888 as a specific photolabel, we have recently demonstrated by antibody mapping methods that the phenylalkylamine binding domain of the channel is located within segment IVS6 or the adjacent intracellular amino acids next to a proposed intracellular Ca2+-binding domain of the channel (6). Application of similar methods to identification ofthe regions of the al subunit photolabeled by the DHPs diazipine, azidopine, and PN200-110 is reported here and in a preceding paper (7). The three ligands possess almost identical binding properties to membrane-bound and purified L-type Ca2+ channels (8-12) but are structurally different. Diazipine and azidopine contain photoreactive diazirine and phenylazide groups, respectively, which are located on a side chain up to 14.3 A (11) from the DHP ring, the proposed binding center. In contrast, the photosensitive benzofurazane group of [3H](+)-PN200-110 (13) is located in close proximity to the DHP ring and therefore is expected to label only segments of the al subunit that are directly involved in formation of the DHP binding site. EXPERIMENTAL PROCEDURES Materials. Reagents were obtained from the following sources: [3H](+)-PN200-110 (70 Ci/mmol; 1 Ci = 37 GBq), [3H]azidopine (45 Ci/mmol), Econofluor, and Protosol were from New England Nuclear; L-1-tosylamido-2-phenylethyl chloromethyl ketone-treated trypsin (TPCK-trypsin) (from bovine pancreas) and trypsin inhibitor (from soybean) were from Sigma; endoproteinase Lys-C was from Boehringer Mannheim; prestained molecular weight marker proteins were from BRL; and unlabeled PN200-110 was a gift from Sandoz-AG (Basel, Switzerland). Sequence-Directed Antibodies. Polyclonal antisera were raised in rabbits against synthetic Ca2+-channel peptides (CP) corresponding to sequences of the skeletal muscle al subunit (14) with a lysine residue added to the N terminus. Peptide synthesis, coupling to bovine serum albumin, and antibody generation were described (6, 15). Affinity purification of anti-CP-(1025-1040) and anti-CP-(1011-1026) was carried out on Sepharose 4B derivatized with the corresponding peptides (6). Elution was achieved with 5 M MgCl2. Preparation of Photolabeled al Subunits. Skeletal muscle Ca2+ channels were partially purified by affinity chromatography on wheat germ agglutinin-Sepharose as described (6). Three to six milligrams (0.9-1.8 nmol; refs. 4 and 5) of affinity-purified protein was incubated with 30-90 nM [3H]azidopine or [3H](+)-PN200-110 in a final vol of 15-25 ml for 60 min at 25°C. A 1to 2-ml aliquot was incubated in the presence of 30 ,uM (+)-PN200-110 to determine nonspecific binding and photolabeling. The incubation mixtures were transferred to plastic Petri dishes on ice and irradiated for 2 min in the presence of 0.2 mM dithiothreitol as described (6) in the case of [3H]azidopine or for 60 min with two 15-W black light lamps at a distance of 10 cm in the case of [3H](+)PN200-110. For some of the [3H](+)-PN200-110 photolabeling experiments, Ca2+ channels were prelabeled with the radioligand before affinity chromatography. Photolabeled samples were processed for immunoprecipitation or digestion as described (6) or dialyzed against 0.05% SDS for further separation by HPLC size-exclusion chromatography (10). Dialyzed samples were lyophilized, resuspended in 0.2-0.3 ml of H20, reductively carboxamidomethylated (6), and separated on a TSK3000SW column (7.5 x 300 mm) connected to a TSK4000SW column (7.5 x 600 mm) in an elution buffer of 0.04 M sodium phosphate, 0.1% SDS at a flow rate of 0.5 ml/min. Fractions containing Abbreviations: CP, Ca2+-channel peptide; DHP, dihydropyridine; TPCK, L-1-tosylamido-2-phenylethyl chloromethyl ketone. 10769 The publication costs of this article were defrayed in part by page charge payment. This article must therefore be hereby marked "advertisement" in accordance with 18 U.S.C. §1734 solely to indicate this fact. 10770 Pharmacology: Striessnig et al. photolabeled al subunits were pooled and stored in small aliquots at -25TC until use. This procedure removed most of the contaminating radioactivity incorporated into proteins other than al. Immunoprecipitation with saturating concentrations of anti-CP-(1339-1354) and anti-CP-(743-759) revealed that 45-65% (range; n = 4) of the total cpm was immunoprecipitable. Proteolytic Cleavage. Photolabeled al subunits were digested with TPCK-trypsin for 120 min at 37TC as described for [N-methyl-3H]LU49888-labeled al (6). Alternatively, size-exclusion HPLC-purified preparations were diluted into 0.1 M Tris-HCl (pH 8.9) containing 0.3% digitonin and appropriate concentrations ofenzymes (0.5-1.0 mg ofTPCKtrypsin per ml or 1.5-3 units ofendoproteinase Lys-C per ml). Samples were digested at 370C overnight. For immunoprecipitation, samples were boiled for 5 min and an aliquot of the digest was removed for direct SDS/PAGE analysis as a nonimmunoprecipitated control. Equivalent volumes of the remaining sample were adjusted to 1% Triton X-100/0.1-0.15 M NaCI/1 mg of bovine serum albumin per ml/1 mg of trypsin-inhibitor per ml (in the case of TPCK-trypsin) and immunoprecipitated with protein A-Sepharose-bound antibodies as described (6).

Since noise emission of starting and landing aircrafts is a major problem for modern airports, it is necessary to put more effort into the research how noise can be reduced sufficiently. An example of effective noise reduction in nature is the barn owl. It is known for long, that the wings of barn owls possess a very unique geometry and special structures, such as leading edge serrations, velvet-like surface, and trailing edge fringes. Those owl-specific characteristics have an influence on the overall flow field and, thus, on the noise emission of the wing. To investigate their impact on the flow field, it is necessary to have a wing whose geometry is based on the geometry of the natural owl wing and which can be equipped with the aforementioned owl-specific structures. The construction of a quasi two-dimensional and a fully threedimensional avian wing for wind tunnel testing and how it is derived from natural owl wings is described. The geometries are based on surface scans of various owl wings. First, a wing model without any owlspecific wing elements and structures ("clean wing") being the reference case for all subsequent measurements is investigated using particle-image velocimetry (PIV) and hotwire anemometry. The main flow feature of the clean wing is a transitional separation bubble on the suction side. The size of the bubble depends on the Reynolds number and the angle of attack, whereas the location was mainly influenced by the angle of attack. Next, a second model with a modified surface is considered and its influence on the flow field is analyzed. Applying a velvet onto the suction side drastically reduces the size of this separation at moderate angles of attack and higher Reynolds numbers.


The tooth supporting tissue is affected by two pathologies: gingivitis and periodontitis. Gingivitis is an inflammatory response of the gingiva to the dental plaque with no destruction of the tissue that surrounds the tooth. Periodontitis is an extension of the inflammatory process with destruction of the connective tissue and the ligament, and bone loss. The bacteria in plaque are the main cause of the periodontal illness.


ABSTRACT Ionospheric delay is the most significant source of error affecting the Loran skywave timing. To improve timing service, we propose a new ionospheric delay estimation method in this paper. It is a cosine model that combines the ionospheric physical characteristics and skywave delay variation law. This semi-empirical and semi-measured model has characteristics of accuracy and simplicity compared with the traditional method. The experimental results show that estimation error of the model is less than 1 µs for a single day and less than 2 µs for 3 days in the stable time. It is sufficient to correct more than 90% of delay when skywave passes through the ionosphere and is less affected by the season. This paper also gives some suggestions on the propagation of ionospheric coefficients required for the model. It allows broadcasting only by modifying the data channel message structure under the normal operation of Loran system.


A study of the double injection currents and recombination electroluminescence in anthracene crystals grown under different inert atmospheres is reported. The results are interpreted in terms of the injection of holes by a field-enhanced tunnelling through a surface barrier. An equation is proposed which satisfactorily describes the current-voltage characteristics over a wide range, and the measured temperature dependence of the current is also in accord with the proposed mechanism.The electroluminescence spectrum from certain crystals showing a broad structureless emission extending to long wavelengths is probably associated with the presence of specific orientations of pairs of anthracene molecules arising from structural imperfections. The intensity of this emission is smaller in relation to the main emission peaks than that previously reported, and shows no direct correlation with the nature of the particular inert gas employed during crystal growth.


Among ocular infections, trachoma is the main cause of blindness. Repeated conjunctival Chlamydia trachomatis infections lead to trichiasis, corneal opacification and visual impairment. Surgery is often needed to relieve discomfort and preserve vision. However, a high recurrence rate is observed. There are many hypotheses that may explain this high failure rate. We systematically reviewed the literature on the pathogenesis and clinical features of postoperative trachomatous trichiasis (PTT) and the evidence for interventions to prevent and manage it.


An approximated Navier–Stokes steady solution is here presented for the two dimensional bluff body wake region that is intermediate between the field on the body scale LD, which includes the two symmetric counter-rotating eddies, and the ultimate far wake. The nonparallelism of the streamlines in the intermediate wake cannot yet be considered negligible. The R is of the order of the critical value for the onset of the first instability and the limiting behavior for large R is not considered. The solution is obtained by matching an inner solution—a Navier–Stokes expansion in powers of the inverse of the longitudinal coordinate—and an outer solution, which is a Navier–Stokes asymptotic expansion in powers of the inverse of the distance from the body. The matching is built on the criteria that, where the two solutions meet, the longitunal pressure gradients and the vorticities must be equal and the flow toward the inner layer must be equal to the outflow from the external stream. At high orders in the inner ...


PurposeThis study analyses interlocking directorates from the perspective of an emerging market, Mexico, where formal institutions are weak, and family firms with high ownership concentration dominate. It responds to recent calls in the literature on interlocks, which urge the differentiation between family and non-family businesses and to complete more research on emerging economies.Design/methodology/approachA database was constructed for 89 non-financial companies (52 family-owned) listed on the Mexican Stock Exchange (BMV) from 2001 to 2014. This period includes normal times and an episode of financial crisis (2009–2010). To test the hypotheses, a dynamic panel model (in two stages) is used, applying GMM.FindingsIn normal times, the advantages of Board Chairman (COB) interlocks for the performance of publicly traded Mexican family firms are obtained regardless of the weak formal institutional environment. By contrast, during financial crisis, interlocking family COBs are more likely to jointly expropriate minority shareholders with actions that further their family objectives, which mitigates the positive effect of interlocks on performance. These findings contrast with the insignificant effects of COB interlocks found for non-family corporates.Originality/valueA new framework is proposed which, through agency theory, finds points of concordance among resource dependence and class hegemony theories, to understand the effect of interlocking directorates on the performance of family firms operating in Mexico. The results of the empirical exercise for family companies listed on BMV during normal and financial crisis periods suggest its applicability.


Formulations of chemically crosslinked and radiation-crosslinked low-density polyethylene (LDPE) containing an intumescent flame retardant such as ammo- nium polyphosphate were prepared. The influence of blending LDPE with a poly(ethylene vinyl acetate) copoly- mer (EVA) and the effects of various coadditives, includ- ing polyethylene grafted with maleic anhydride (PEgMA), vinyl silane with boric acid, and talc, on the mechanical and thermal properties were investigated. Chemical cross- linking by dicumyl peroxide and crosslinking by ionizing radiation from an electron-beam accelerator were both used and compared. Improved mechanical properties were observed by the partial replacement of LDPE with EVA. Similar mechanical or thermal properties were observed with coadditives such as PEgMA and vinyl silane with bo- ric acid. The addition of a small amount of talc improved the tensile strength of the formulations. All crosslinked for- mulations showed good thermal stability on the basis of the retention of mechanical properties after thermal aging for 168 h at 1358C and a hot-set test. 2007 Wiley Periodi- cals, Inc.

In order to maximize the available data rate and spectrum utilization efficiency, a high-throughput satellite communication system adopts the full spectrum reuse scheme, which will cause serious co-frequency interference. In this paper, a forward link model, considering the effects of free space loss, rainfall attenuation, and beam gain, is established, and the classical low-complexity of the zero-forcing precoding algorithm is improved in order to solve the serious co-frequency interference. Moreover, the regularized zero-forcing precoding algorithm considering the influence of system noise is studied, and a low complexity regularized zero-forcing dirty paper precoding algorithm is proposed, whose basic principle is to sort users based on the principle of channel maximum norm selection and practical application scenarios. Simulation results show that it can encode users sequentially, according to the channel conditions, to maximize the SINR (signal-to-interference-plus-noise ratio) and increase the throughput of the system.

Basing ourselves on a novel segmentation algorithm for multi-spectral images, we have considered how to detect multi-pixel anomalous objects in image cubes with a spectral component. In particular, we have developed several filters to compensate for noise which may be present in the initial cube. We show that for speckle noise, a modification of our morphology technique allows us to detect targets without an enhanced false alarm result.

Calcineurin‐inhibitor refractory bronchiolitis obliterans (BO) represents the leading cause of late graft failure after lung transplantation. T helper (Th)2 and Th17 lymphocytes have been associated with BO development. Taking advantage of a fully allogeneic trachea transplantation model in mice, we addressed the pathogenicity of Th cells in obliterative airway disease (OAD) occurring in cyclosporine A (CsA)‐treated recipients. We found that CsA prevented CD8+ T cell infiltration into the graft and downregulated the Th1 response but affected neither Th2 nor Th17 responses in vivo. In secondary mixed lymphocyte cultures, CsA dramatically decreased donor‐specific IFN‐γ production, enhanced IL‐17 production and did not affect IL‐13. As CD4+ depletion efficiently prevented OAD in CsA‐treated recipients, we further explored the role of Th2 and Th17 immunity in vivo. Although IL‐4 and IL‐17 deficient untreated mice developed an OAD comparable to wild‐type recipients, a single cytokine deficiency afforded significant protection in CsA‐treated recipients. In conclusion, CsA treatment unbalances T helper alloreactivity and favors Th2 and Th17 as coexisting pathways mediating chronic rejection of heterotopic tracheal allografts.


This paper concludes that transparency, openness, and objectivity, are important parts of the American ideal of rule of law. Yet these procedural refinements seem to contribute more to the problem than to a solution. All the emphasis on doing things the right way distracts us from seeing that we are doing the wrong thing. Protection for U.S. production beset by import competition is what the antidumping and countervailing duty laws are all about, contends the author. Only in rhetoric are the unfair trade procedures about what foreign sellers are doing and about whether what they are doing is fair or unfair. The legal definitions of what is unfair offer so many possibilities that any U.S. producer who would be better off if imports were restricted can find a way to qualify - if not now, then after the next trade bill. The focus of trade regulation should be the following question: Who in the domestic economy will benefit from the proposed restriction and who will lose, and by how much ? Then get the economics right. Finally, the author concludes that the idea that there are gains from trade, usually greater than the costs, has been around since Adam Smith. It is just that they have never been made legal in the United States.


The McEliece cryptosystem is the asymmetric type of cryptography which is based on error correction code. The classical McEliece used irreducible binary Goppa code which considered unbreakable until now especially with parameter [1024, 524, 101] which is suggested by McEliece, but it is suffering from large public key matrix which leads to be difficult practically. In this paper a new design has been introduced and implemented for McEliece Cryptosystem which is graphical user interface (GUI) using Visual Studio c#, and two types of binary Goppa code have been used. Also for the first time McEliece cryptosystem has been implemented using separable binary Goppa code.

Smart materials such as stimuli responsive polymeric hydrogels offer unique possibilities for tissue engineering and regenerative medicine. As, however, most synthetic polymer systems and their degradation products lack complete biocompatibility and biodegradability, this study aims to synthesize a highly magnetic responsive hydrogel, based on the abundant natural biopolymer collagen. As the main component of vertebratal extracellular matrix, it reveals excellent biocompatibility. In combination with incorporated magnetic iron oxide nanoparticles, a novel smart nano-bio-ferrogel can be designed. While retaining its basic biophysical properties and interaction with living cells, this collagen-nanoparticle hydrogel can be compressed to 38% of its original size and recovers to 95% in suitable magnetic fields. Besides the phenomenology of this scenario, the underlying physical scenarios are also discussed within the framework of network models. The observed reversible peak strains as large as 150% open up possibilities for the fields of biomedical actuation, soft robotics and beyond.

Mobility models play a key role in the evaluation of wireless network protocols and applications. Simulation results obtained with an unrealistic model may not reflect the true performance of a system in real environments. Besides, different environments may be characterized by different patterns of mobility which require simulation scenarios to be supported by suitable mobility models. The choice of the mobility model and its parameters has significant impact on the result of the simulations. In this paper we present MONGOOSE (MObility sceNario Generation tOOl for Structured Environments), a highly flexible and easily extendable software tool for the simulation of mobility scenarios in structured environments such as shopping malls, urban areas, museums, schools, hospitals, music festivals, amusement parks, stadiums, airports. Moreover, new mobility models can be easily added to the list of those already provided and some of their mobility parameters and simulation playground can be described without programming requirements. Here, we use MONGOOSE to show the impact of four different mobility models on the performance of two well-known delay tolerant routing protocols, Epidemic and Prophet.

The short-run response of output to devaluation and monetary policies is investigated for economies where firms are constrained to finance in advance their working capital by borrowing solely from domestic banks. It is shown that in contrast with traditional theories, but in accordance with recent theoretical and empirical analyses for developing countries, an anticipated devaluation or an anticipated decrease in the level of the exogenous component of money might result in a short-run output contraction even if prices fully adjust to clear markets. In addition, the paper analyses how output responds when a devaluation is unanticipated or when agents cannot distinguish between temporary and permanent monetary shocks.


This book focuses on two main areas – first, the response of British Lubavitchers to misfortune generally and sickness, in particular and the role of their religious leader the Rebbe in this process; and second, their response to the illness and ultimate death of the Rebbe. It addresses a number of issues in contemporary social and medical anthropology: the social construction of the body, the power of words in ritual, the relation between myth and praxis, religious texts as a charter for healing and the relation between the use of biomedicine and symbolic healing. This book will be of interest to students of social anthropology, medical anthropology, medical sociology, millennialism, religious studies and students of contemporary Judaism.


We analyze diffuse X-ray emission from NGC4649, NGC5044 and NGC5846, combining data from two X-ray observatories, ROSAT and ASCA. With ASCA, we perform a detailed analysis of the X-ray emission which properly accounts for the ASCA PSF and also include a 3-dimensional source model. All three sources exhibit cooling flows in their centers. From the derived abundances of Si, S and Fe, we conclude that NGC5044 (a dense group of galaxies) was able to retain significant amounts of gas during an early galaxy wind phase. Fe abundance in NGC5846 (normal E galaxy) corresponds to current SNIa rate of ∼ 0 . 2 of Tammann rate, while low Fe mass in NGC4649 (normal E in the Virgo cluster) could be an environmental effect.


With the use of IR-, 13C NMR in the solid the sorption of zinc cations from aqueous solutions by humic acids was investigated. The objects of study were selected native and modified humic acids extracted from brown coal of deposit Tisulsky (section Kaychaksky) and its naturally-oxidized form. It is shown that the sorption of zinc cations takes place by ion exchange mechanism. Modification of humic acids by hydrogen peroxide leads to increase in the content of oxygen-containing functional groups and their sorption capacity increases in 2-4 times.


Introduction of computers in libraries has immensely enhanced the effectiveness of library services including efficient organization and retrieval of information activities. Since the application of information technology in libraries, one of the greatest challenges before the library managers is the selection of a good library automation software package which can cater to the needs of a particular library. In India, library automation process started in the last decade of the previous century. Many Indian as well as foreign software companies had entered into the market. Nevertheless, only a couple of library automation software packages gained success in making their presence felt into Indian market. The present article discusses the salient features of cataloguing module of three such packages, namely, Alice for Windows, Libsys and Virtua and their acceptability in a developing nation.

Work accidents are a major issue in occupational safety and health. Employees of companies that offer telecommunications services are exposed to work accidents, especially during installation and operation of radio networks, operations that involve, in most cases, working at height (e.g. telecom towers or pylons). The exploiting of risk assessment tools by the ones involved in this business could cut both human and financial losses caused by workplace hazards. Starting from this premise and using a knowledge-based application, this paper presents a risks assessment tool for work accidents that has as main features the probability and the severity of consequences in hazards that can come about in the telecommunications industry.


Industry 4.0 is revolutionising recent industrial setups. Literature has examined the idea of Smart Factory under the umbrella of Industry 4.0 extensively, but further research into the applicability of such frameworks for Small to Medium Size Enterprises (SMEs) is still required. To help address this issue, the Agent-Oriented Smart Factory (AOSF) framework focuses on a multi-agent architecture for end-to-end Supply Chain (SC) in SMEs. This paper presents a Cyber Physical System (CPS) based extension to the general AOSF framework and design heuristics for problem and domain definition of Agent Oriented Storage and Retrieval (AOSR) warehouse system using Multi-Agent Hierarchical Task Networking (MA-HTN) planning formalism.

Patients with Cystic Fibrosis (CF) have an increased incidence of bronchial hyper-reactivity to inhaled methacholine (MCh). There is also an increased skin reactivity to inhaled allergens and an increased incidence of allergic rhinitis. Thus, CF shares some clinical features with asthma and drugs used in asthma may be useful in CF.Sodium cromoglycate (SCG) is efficacious in asthma, blocking some patients against MCh challenge and decreasing bronchial hyper-reactivity. We studied the potential role of SCG in CF by determining if it could block acute bronchoconstriction induced by MCh, and predict CF patients whose bronchial hyper-reactivity and symptoms would lessen with longterm use.Fifteen CF patients known to respond to an MCh challenge were studied. None had clinical asthma, nor had intercurrent infections at the time of the study. Three standard MCh challenges were performed on consecutive days at the same time; two after placebo (distilled water) and one after 2ml 1% SCG, which were given in random order in a double-blind manner. As well as providing a baseline, the two placebo studies provided a measure of the reproducibility of the MCh challenges (variation less than 10%). There were only small changes in FEV1 after placebo and SCG (less than 6%). The mean FEV1 was 65% (range 32-90) and PD20 was calculated from the dose-response curves of cumulative MCh inhaled versus drop in FEV1. Four patients (27%) were completely protected by SCG. We conclude that longterm trials of SCG in CF are indicated to assess predictive ability of MCh challenge blocking for improved symptom scores and decreased MCh sensitivity. SCG may benefit selected CF patients.

Armenian relativistic formulas is full of asymmetry, which is in every single formula because of coefficient asymmetry s and that asymmetry is the essence and exciting part of the Armenian Theory of Relativity and therefore we demand a revision of all legacy mechanics under these remarkable new circumstances. The time has also come to reopen NASA's BPP program, but this time using our everywhere existing Armenian asymmetric formulas. This will lead us to harness infinite energy from rest particle's momentum-energy just as we harness energy from the wind using a windmill. Going in this path will bring forth the dawn of a new technological era. It is worth to mention again that all legacy physics (classical and relativistic) transformations and formulas can be obtained from Armenian Theory of Relativity as a very special case by substituting s = 0 and g = -1. In the end we like to make a statement that: Armenian Theory of Relativity is a Theory of Asymmetric Relativity. 100 years of inquisition in physics is now over and Ether Energy Age has begun!

Case study / Research paper Themes: What are the emerging practices, tools and approaches that may enhance student learning? What is the role of research and evaluation in the post digital university? Keywords: Screencasts, Active learning, Attainment, Data Analysis Abstract This session will describe how screencasts have been used to supplement lecture material in order to increase students' understanding of the material taught.  Inspiration originally came from a conference presentation on the flipped classroom by Andrew Douch (Douch, 2012). Rather than provide students with a written solution to a tutorial question, as in previous years, students were provided with a screencast in MP4 format showing the lecturer going through a question in detail explaining why they were doing it in a particular way.  The students can see and hear the thinking, listen when they want and understand the process and not just the result (Fahlberg, 2007).   The content varied in detail so the one for the first question contains more information about the thinking process and the different ways of addressing the problem than those for subsequent questions. Students commented favourably saying that they wished other staff would do these as they liked hearing the explanations.  They appreciated that they could pause the video, rewind and play again to make sure that they had indeed understood the method.  Students reported that this enabled them to understand the problem without the need to ask further questions.  As in similar research it was found that this helped students take control of their own learning (Morris and Chikwa, 2014). In the first year of using these screencasts, marks for both coursework and exam improved whereas the standard of the work set (as moderated by internal and external examiners) and the general ability of the students (as measured by their achievement in other modules) is thought to have remained the same.  Results suggested that the videos had contributed to the students' improved performance and had assisted their learning. In the Post Digital Age more data is available.  This includes data on students' grades, attendance and the number of times they have accessed lecture notes, tutorial questions and the screencasts.  Multiple Linear Regression has been carried out on recent data to see whether there is any statistical evidence to show that providing the screencasts has indeed increased the students' understanding and learning.

IgA vasculitis is generally considered to be a self-limiting condition, but this is at odds with the increased mortality observed in adult patients with IgA vasculitis (1).With sparse data on prognostic factors in IgAV, we investigated whether pre-existing conditions are risk factors for mortality in adult IgAV patients.Observational population-based cohort study using state-wide linked longitudinal health data for adults with IgAV (n=267) and matched controls (n=1080) between 1980-2015. Charlson comorbidity index (CCI) and serious infections (SI) were recorded over an extensive lookback period prior to diagnosis. Date and causes of death were extracted from the WA Death Registry. Mortality rate (deaths/1000 person-years) ratios (MRR) and time dependent survival analysis assessed the risk of death. Age and gender specific mortality rate data were obtained from the Australian Bureau of Statistics.During 9.9 (±9.8) years lookback IgAV patients accrued higher CCI scores (2.60 vs1.50 p<0.001) and had higher risk of SI (OR 8.4, p<0.001), not fully explained by CCI scores. During 19 years follow-up, the risk of death in IgAV patients (n=137) was higher than in controls (n=397) (MRR 2.06, CI 1.70-2.50, p<0.01) and the general population (SMRR 5.64, CI 4.25, 7.53, p<0.001). Survival in IgAV was reduced at five (72.7 vs. 89.7 %) and twenty years (45.2% vs. 65.6 %) (both p<0.05). CCI (HR1.88, CI:1.25 - 2.73, p=0.001), renal failure (HR 1.48, CI: 1.04 - 2.22, p=0.03) and prior SI (HR 1.48, CI:1.01 – 2.16, p=0.04) were independent risk factors. Death from infections (5.8 vs 1.8%, p=0.02) was significantly more frequent in IgAV patients.Premorbid accrual of comorbidity is increased and predicts premature death in IgAV patients. However, comorbidity does not fully explain the increased risk of serious infections prior to diagnosis or the increased mortality due to infections in IgAV.[1]Villatoro-Villar M, Crowson CS, Warrington KJ, Makol A, Ytterberg SR, Koster MJ.

The study analyzed the economics of pineapple production in Awgu Local Government Area (LGA) of Enugu State, Nigeria. Data for the study were collected from 50 respondents from Amoli and Ihe communities of the LGA through a simple random sampling technique. The communities were purposively selected because they contain higher concentration of pineapple farmers. Primary data were collected using interview schedule administered to the respondents. Data were realized with descriptive statistics, enterprise budgeting techniques and multiple regression analysis. The study revealed that (36%) of the farmers had farming experience of 1 to 10 years' experience in pineapple production, indicating that new farmers entered the crop's production sector within the last decade. The enterprise proved profitable with farmers' net return on investment value of 1.7. Farm size, cost of input, level of education and household size significantly determined net farm income. It was further revealed that poor access road and high transportation cost were the main constraints of the pineapple producers. The study concluded that profitable production opportunities exist on the crop. The study recommends that extension agencies should encourage more new farmers to exploit pineapple production potentials while encouraging its existing farmers to scale up production through farm size increment, reinvestment of their gains and production knowledge increase.


In order to overcome the difficulty of online measuring the main components in the process of capturing CO2 from the flue gas of a power plant based on absorption method,a soft-sensing system was designed for the process of recovering CO2 by MEA chemical absorption.Based on the principle of improved Powell robust support vector machine (IP-RSVM),the soft measurement of ionic species distribution in the absorption solution was carried out by using infrared sensors,and the results agreed well with the data obtained by nuclear magnetic resonance (NMR) measurement.The mean square error was 3.1692×10-7,the maximum value of absolute error was 0.0010,and the maximum value of relative error was 3.54%.It showed that the infrared soft measurement based on IP-RSVM could be used in the soft-sensing system of capturing CO2 effectively.


This thesis aims to contribute toward a proposal to set up a very low frequency (VLF: . 30 MHz) radio observatory on the lunar surface. The primary motivation for this proposal is to learn about our universe through a completely new spectral window in astronomy by taking advantage of the unique lunar environment. The secondary motivation is to take on a challenge of building and operating a facility on the Moon, especially through international cooperation, and to inspire everyone who looks at the Moon. After explaining these motivations and reviewing foregoing efforts toward this cause, the thesis examines unsolved questions about the advantages of the lunar environment, proposes a preliminary observatory to be set up at the lunar south pole, and identifies desirable measurements to be made at the earliest opportunities. Chapter 1 describes the motivations for astronomy from the Moon, particularly at very low frequencies. The Moon offers a unique environment that enables astronomical observations that are otherwise impractical. In particular the Moon can be utilized as a shield against unwanted radiations and as a large stable platform. These advantages are crucial for VLF astronomy. Thus far the Earth's ionosphere and interference have prevented any detailed observations at frequencies below ∼30 MHz, keeping this VLF window the only part of the electromagnetic spectrum yet to be explored in astronomy. Accordingly the potential for unexpected discoveries is significant. The lunar far side may well be the only accessible site that enables sensitive galactic and extragalactic VLF observations. To realize this idea, Chapter 2 reviews the extensive foregoing efforts toward a Moonbased VLF observatory and identifies the next steps. The idea began in the mid-1960s and was advanced significantly during the 1980s, especially at a workshop dedicated to a lunar far side VLF array. In the 1990s, serious design studies were conducted by the Hughes Aircraft Company, the International Space University, and the European Space Agency. Referring to all these work, this chapter presents a background on observational considerations and the observatory design. The current consensus seems to be that although an array on the far side of the Moon is scientifically ideal and technologically feasible, funding is unlikely until the far side access becomes inexpensive. To accelerate the pace for this proposal, the key is probably to raise people's interest in this project and its significant discovery potential. Also, the necessity of the Moon should be reaffirmed (Chapter 3), an affordable preliminary VLF array should be proposed for an initial sky survey (Chapter 4), and necessary measurements should be made utilizing every opportunity presented by the upcoming lunar missions (Chapter 5). Chapter 3 examines questions that must be resolved to confirm the advantage of the lunar surface for a VLF observatory. We must verify that (1) the Moon can shield the interference sufficiently, (2) any lunar ionosphere does not limit the observations, and (3) the lunar surface and subsurface do not disturb the observations, To address various issues relevant to the VLF array project, a general tool was developed to simulate the propagation of radio waves in the lunar environment. This tool was used to investigate (1) how radio waves penetrate into the lunar surface for possible subsurface reflections back up to the antennas, and (2) how well the Moon shields long wavelength radio interference. On the far side locations over half way (45 degrees) from the limb, the simulations seem to show that radio waves would be attenuated by at least 10 orders of magnitude, even at a very low frequency of 50 kHz. Prior to a full-scale observatory on the lunar far side, a crucial step now is to propose a realistic preliminary version at a more accessible site on the Moon, examined in Chapter 4. It will be for conducting an initial sky survey and testing an array on the lunar surface. The most economical method of deploying such lightweight antennas could be as a piggyback payload on some funded lander, most likely to the lunar south pole. This way, the project can utilize the same transportation, power, and communication systems required for further lunar development. A study was conducted to explore the possibility of using the 5-km tall Malapert Mountain near the lunar south pole as a shield against terrestrial radio interference. Simulations seem to indicate a several orders of magnitude attenuation over a region spanning ∼50 km on the far side of Malapert Mountain. A preliminary concept is developed for the first lunar VLF array to be deployed in this shadowed region. To be able to choose the site and design the observatory, Chapter 5 makes recommendations for specific measurements to be proposed for upcoming missions including SMART-1, LunarSat, and SELENE. It is especially critical to obtain detailed topology at candidate sites and to determine the electron density profile above the lunar surface at various times and locations. The final chapter includes my vision for how an international effort can make this project happen. Suggestions are given for an orbiting precursor array by∼2010, a surface array near the lunar south pole by ∼2015, and ultimately a far side array after 2020. Many nations share similar ambitions toward the Moon, including the United States, European Union, Japan, China, India, Canada, and Russia. Let us begin seriously exploring how to turn the individual objectives into a united proposal. I believe the Moon offers unique and significant opportunities for inspiring and uniting everyone on Earth.


The rapid evolution of machine learning applications along with the exponential growth in the Internet of Things (IoT) has driven a surge in demand for high-performance and energy-efficient hardware solutions for Edge AI applications. While traditional Edge AI hardware either falls short in performance or incurs massive power/area overhead, this paper presents a novel RISC-V processor core architecture with instruction set architecture (ISA) extensions that achieves up to 37x performance improvement for a General Matrix Multiply (GEMM) kernel compared to a baseline RISC-V core. Furthermore, this paper proposes an end-to-end framework named LiteAIR5 that encompasses system-level modeling of ISA-extended RISC-V cores, System-on-Chip Generation, Compiler Support, and FPGA emulation. This all-encompassing framework provides users with the ability to develop optimized AI hardware while also taking into account the effects on the entire system.

Cardiovascular diseases (CVD) are considered a major health problem worldwide, being the main cause of mortality in developing and developed countries. Endothelial dysfunction, characterized by a decline in nitric oxide production and/or bioavailability, increased oxidative stress, decreased prostacyclin levels, and a reduction of endothelium-derived hyperpolarizing factor is considered an important prognostic indicator of various CVD. Changes in cyclic nucleotides production and/ or signalling, such as guanosine 3', 5'-monophosphate (cGMP) and adenosine 3', 5'-monophosphate (cAMP), also accompany many vascular disorders that course with altered endothelial function. Phosphodiesterases (PDE) are metallophosphohydrolases that catalyse cAMP and cGMP hydrolysis, thereby terminating the cyclic nucleotide-dependent signalling. The development of drugs that selectively block the activity of specific PDE families remains of great interest to the research, clinical and pharmaceutical industries. In the present review, we will discuss the effects of PDE inhibitors in CVD related to altered endothelial function, such as atherosclerosis, diabetes mellitus, arterial hypertension, stroke, aging and cirrhosis. Multiple evidences suggest that PDEs inhibition represents an attractive medical approach for the treatment of endothelial dysfunction-related diseases. Selective PDE inhibitors, especially PDE3 and PDE5 inhibitors are proposed to increase vascular NO levels by increasing antioxidant status or endothelial nitric oxide synthase expression and activation, and to improve the morphological architecture of the endothelial surface. Thereby, selective PDE inhibitors can improve the endothelial function in various CVD, increasing the evidence that these drugs are potential treatment strategies for vascular dysfunction and reinforcing their potential role as adjuvant in the pharmacotherapy of CVD.


XMASS is a multi-purpose underground detector using ultra pure liquid xenon whose aim is searching for dark matter, double beta decay and low energy solar neutrinos. The first physics target is the detection of dark matter and R&D studies have been performed using a 100kg detector. Here, the detector performance checks will be presented. The detector consists of a 31-cm size cubic capper chamber, 54 2-inch PMTs, and shielding to eliminate outside backgrounds such as betas, gammas and neutrons. First, since the signal of dark matter is expected at low energy region below several tens of keV, it is important to reduce backgrounds in this energy region. Therefore, the self-shielding performance of liquid xenon, which is a key idea for reduction of backgrounds, in 100kg detector is checked using a radioactive source from outside of the detector. It is consistent with expectation. Next, the source of backgrounds is studied. In order to understand backgrounds, a precise detector simulation is needed. Several parameters, e.g. light absorption and scattering in liquid xenon and reflection on the surface of copper and PMTs should be obtained for the detector simulation. Those are studied using about 4days of data. Comparing data and MC, the background level inside the fiducial volume is consistent with expectation. Each remaining backgrounds source is also estimated and will be presented.

Common Criteria and ISO 27001/IT-Grundschutz are well acknowledged evaluation standards for the security of IT systems and the organisation they are embedded in. These standards take a technical point of view. In legally sensitive areas, such as processing of personal information or online voting, compliance with the legal specifications is of high importance, however, for the users' trust in an IT system and thus for the success of this system. This article shows how standards for the evaluation of IT security may be integrated with the KORA approach for law compatible technology design to the benefit of both – increasing confidence IT systems and their conformity with the law on one hand and a concrete possibility for legal requirements to be integrated into technology design from the start. The soundness of this interdisciplinary work will be presented in an exemplary application to online voting.


New Testament scholars have long debated whether 2 Cor 6.14–7.1 originally stood at its present location in 2 Corinthians and, indeed, whether the passage should even be attributed to Paul. The verses have variously been viewed as (a) composed by Paul specifically for inclusion at their present location, (b) composed by Paul for some other occasionPerhaps as part of the earlier letter mentioned in 1 Cor 5.9–11. but subsequently included at their present location either by Paul or by someone else, (c) composed by someone other than Paul but included at their present location by Paul, or (d) both composed by someone other than Paul and included at their present location by someone other than Paul (not necessarily the same person).For a good summary of scholarship since the Reformation, see William J. Webb, Returning Home: New Covenant and Second Exodus as the Context for 2 Corinthians 6.14–7.1 (JSNTSup 85; Sheffield: Sheffield Academic, 1993) 16–30; see also, e.g., Victor Paul Furnish, II Corinthians: Translated with Introduction, Notes, and Commentary (AB 32A; Garden City, NY: Doubleday, 1984) 375–83. It is not my intention in this brief study to address the question of authorship; rather, I propose simply to look at one aspect of the question whether this passage originally stood at its present location in 2 Corinthians – that is, at the relation between 2 Cor 6.14–7.1 and its immediate context (6.11–13 and 7.2–3).


High irradiance testing of consumer electronics is growing in popularity, but without a precise understanding of the methodology, testers run the risk of inaccurate or misleading results, says Atlas Material Testing Technology.


Leaf blight Phytophthora colocasiae is one of the main diseases in taro plants which can reduce production yield significantly. Weather is one of the main factors supporting the epidemic of leaf blight. Weather changes will affect the development of pathogens and affect the development of disease in the field. This research aimed to find out the effect of weather elements (air temperature, humidity, sunlight intensity, rainfall, number of rainy days) on the intensity of the taro leaf blight attack. The results showed that weather elements had a significant correlation with the intensity of taro leaf blight disease. Air temperature and sunlight intensity showed negative correlations while air humidity, rainfall and the number of rainy days were positively correlated with the disease intensity. The results of this path analysis showed that air humidity had the most significant effect of the weather elements on the intensity of taro leaf blight both directly and indirectly.


A rotary automatic temperature measurement device includes a rotary temperature signal acquisition mechanism, a measuring and controlling instrument, a computer and a digital voltmeter. The rotary temperature signal acquisition mechanism is used for rotating temperature measurement. The mechanism is connected with the measuring and controlling instrument and transforms the acquired temperature of an exhaust temperature field into an electric signal, which is transmitted to the measuring and controlling instrument. The measuring and controlling instrument is connected with the computer and the digital voltmeter. The digital voltmeter which is connected with the computer transforms an electric signal received from the measuring and controlling instrument into a digital signal and transmits the digital signal to the computer. The computer transforms the digital signal received from the digital voltmeter into temperature field data to be output to finish the temperature measurement. The temperature measurement device can finish the temperature measurement of an engine exhaust field by starting the engine just for one time. The temperature field measurement of 240 temperature measuring points can be finished within two minutes.


Teatro Abierto first appeared in 1981 in Buenos Aires during the "Process of national reorganization" (1976-1983), one of the most tragic dictatorship Argentina ever endured. It was a theatrical phenomenon meant to reaffirm the existence of Argentine theatre though being the victim of censorship. However, as the performances went on, and thanks to public support, it eventually became a political movement opposed to the regime. The success of this venture would incite the artist to repeat the experience. More than ninety plays, performed during four seasons, were indeed proposed to the portenos spectators. What means did the plays use to denounce some of the reality of the time ? The analysis of the movement and of the plays performed between 1981 an 1983 shows that while Teatro Abierto was first and foremost considered as a political phenomenon, not only by the critics but also by the artists themselves, it was also at the root of important actworks in the argentine theatrical scene.


Due to their unique, tailorable and diverse combination of properties, such as good mechanical properties, low density, rather low cost, ease of processing, resistance to most chemicals, polymers are nowadays the most widely used materials in diverse different fields. The world plastic production in 2013 achieved 299 million tonnes, and from Europe 57 million tonnes, the latter level being similar to those in 2012 (Source: PlasticsEurope (PEMRG) / Consultic). In 2012, 25.2 million tonnes of post-consumer plastics waste ended up in the waste upstream. Even though recycling and energy recovery processes have increased since 2006, in 2012 around 62% of waste was recovered through recycling (26%) and energy recovery processes (36%), 38% of plastic waste still goes to landfill. Part of the plastic waste can even find the way into the natural environment, where it represents a source of organic pollution and hazard for animals that can accidentally ingest it, entangle themselves in it, or suffocate from it. Today, almost all plastics (80%) are synthesized from raw materials which derive from fossil fuels via the petrochemical industry. Thus, their waste represents a loss of precious non-renewable resource of materials. Nevertheless, an efficient, complete and feasible treatment for any kind of waste polymers remains a difficult challenge: thus, landfilling is still the 1st option


The term 'agentive' is a familiar one in current discussions of the syntax of English (and other languages). Although most who use it seem, at first glance, to be referring to more or less the same semantic feature, the term is employed in a variety of ways. For instance, Fillmore (I968: 24) talks of an 'agentive case'; Gruber (I967: 943) has 'agentive verbs'; Lyons and others speak of 'agentive nouns'; while Halliday (I967: I96), although he does not use the term 'agentive', distinguishes a feature of clauses which is clearly related to the notion of agentivity. Apart from this disagreement as to what, precisely, the term 'agentive' is to be predicated of, there is a further divergence of opinion over which nouns (or verbs, etc.) are to be considered agentive. For instance, Lyons marks the surface subject of see as agentive (I968: 387). Fillmore, on the other hand, assigns this to the dative case, and Gruber classifies see as a non-agentive verb. Again, Lyons and Halliday take up what are in effect incompatible positions with regard to the status of the prisoners in John marched the prisoners. In view of this indeterminacy, it seems worthwhile to attempt a critical examination of the notion of agentivity, in the hope that a clearer characterization of it might emerge. Despite the cheerful intuitivism frequently detectable in discussions involving agentivity, attempts to characterize the notion more precisely are by no means lacking. We can distinguish two main types of characterization; first, attempts to define agentivity in referential terms; and, secondly, purely linguistic definitions which relate the feature to the meaning of the surface lexical item do. An example of the first type is Fillmore's statement that agentive is '. . . the case of the typically animate perceived instigator of the action identified by the verb' (I968: 24). Fillmore in effect apologizes for the phrase 'typically animate' in a footnote. We are left with no way of identifying inanimate agents (although the definition does seem to leave open the possibility that such exist). Comparing, for instance, John overturned the dustbin and The wind overturned the dustbin, it is difficult to see how the wind is any less of an agent than John: indeed, we commonly describe the sun, wind, frost, etc., as 'natural agents', without, surely, attributing animateness to them. But other difficulties lie behind this definition. Why speak, for instance, of 'the PERCEIVED instigator'? Perceived by whom -


Developing cyber physical systems is hard since it requires a coordinated, physics-aware allocation of CPU and network resources to satisfy their end-to-end qua lity-of-service (QoS) requirements. This paper provides two contributions to address these challeng es. First, we present model-driven middleware called NetQoPE that shields application developers from th e complexities of programming the lowerlevel CPU and network QoS mechanisms by simplifying (1) the s p cification of per-application CPU and per-flow network QoS requirements subject to the physica l constraints and dynamics, (2) resource allocation and validation decisions (such as admission con trol), and (3) the enforcement of per-flow network QoS at runtime. Second, we empirically evaluate how NetQoPE provides QoS assurance for CPS applications. Our results demonstrate that NetQoPE provid es flexible and non-invasive QoS configuration and provisioning capabilities by leveraging CPU and networ k QoS mechanisms without modifying application source code.


Myocardial ischemia is associated with increased production of cyclic adenosine monophosphate (cAMP), with potentially deleterious effects. We hypothesized that the ischemia-induced activation of cAMP-dependent protein kinase A (PKA), could beneficially be inhibited by a PKA-inhibitor N-(2-[p-bromocinnamylamino]ethyl)-5-isoquinoline-sulfonamide (H-89). H-89 when given to isolated perfused rat hearts before 30 minutes of global ischemia-reperfusion improved postischemic function and decreased infarct size. In another series, H-89 administered prior to preconditioning by 10 minutes of transient global ischemia decreased PKA activity (measured at the end of the preconditioning protocol) and augmented postischemic mechanical recovery. H-89 given for 5 minutes before the 10 minutes of transient ischemia further decreased infarct size from 13.4 ± 1.0% (preconditioning alone) to 7.0 ± 0.93 (P < 0.01). In a third series, forskolin (0.3 μM, 5 minutes, 10 minutes washout prior to ischemia) increased PKA activity and reduced infarct size. Prior H-89 decreased PKA activity after 5 minutes of forskolin and further reduced infarct size versus forskolin alone. In conclusion, three procedures increased postischemic recovery and reduced infarct size: H-89; preconditioning by transient ischemia; or forskolin as a preconditioning-mimetic. PKA-inhibition by H-89 further decreased infarct size beyond preconditioning or forskolin. Despite the reservation that H-89 could be non-selective in its actions, we propose H-89 as a candidate cardioprotective agent.


A self-calibrating analog-to-digital converter using binary weighted capacitors and resistor strings is described. Linearity errors are corrected by a simple digital algorithm. A folded cascode CMOS comparator resolves 30 /spl mu/V in 3 /spl mu/s. An experimental converter fabricated using a 6-/spl mu/m-gate CMOS process demonstrates 15-bit resolution and linearity at a 12-kHz sampling rate.

Indonesia is a collectivist country that adopts their traditional law called adat as part of their system besides constitution and Islamic law. Adat has sets of rules for marriage and much of the time, Indonesian are confirmed to the rule. But the survey shows that there is evidence of a woman who decided not to get married despite adat rules. Thus, this study explores the reason women who decided to not marry using a phenomenological approach to capture their experience leads to the decision. The study found that family is the main reason for their decision. They experience their parents' divorce and demanding family whose follow adat rule and suppress them to marry. Therefore, both participants decided marriage is not for everyone and not the only source of happiness.


Early language learning is once again high on the government ' s agenda. The Language Learning section of the recently published Green Paper states, 'we will give each child an entitlement to learn a language at primary level by 2012. ' Sharpe 's authoritative book has therefore appeared at an opportune moment. In it, he aims to tackle in a 'thought provoking manner' the 'what, why and how' of early MFL teaching a daunting task in view of the perceived failure of the 1960s Pilot Scheme 'French from Eight'. Intended readers are primary and secondary teachers, head teachers, trainee teachers, governors, LEA officers, educational consultants and parents. He recalls in Part 1, 'the why', key events in the growth and subsequent decline of PMFL initiatives some thirty years ago, drawing out lessons for the present as he does so. A discussion of possible aims and objectives incorporates a description of the strands of communicative competence, together with the benefits accruing from early language learning, including the subject 's contribution to citizenship education related to the need for children to become both multilingual and multi-cultural. The consideration in Part 2, 'the what and when', of the post 2000 NC for MFL makes the point that the former areas of


The team of international requirements engineering board enabled standardization in what a requirement analyst is and does, the team has established a common vocabulary for talking about task, techniques, skills and roles. It has also created a syllabus and examinations for certifying such analysts, with the goal being that a certified requirements analyst should know important terms and techniques and be able to apply them to examples. In this paper, the concept of certification of requirements analyst is discussed. The author focused on the issues of in favor and against of the certification.


'No authority was cited or evidence introduced to establish that transparency has become part of customary international law' So said Tysoe J. of the Supreme Court of British Columbia, disagreeing with the arbitral Tribunal in the Metalclad case under NAFTA Chapter 11.1 Is Tysoe J. correct? Some very prominent courts take a restrictive view toward the recognition of international customary law. Some very prominent international arbitrators have less difficulty finding it.

The concept of international customary law of transparency and security for international investors under bilateral and multilateral investment treaties is familiar to international commercial arbitrators. The content of that concept is, however, far from clear. This article will first examine how the United States federal courts have recently defined international customary law. Second, it will examine how the oft cited Metalclad arbitration award under Chapter 11 of North American Free Trade Agreement defines transparency of governmental administration as it relates to investors protected by investment treaties. Third, it will examine how a number of recent arbitral Tribunals and the World Trade Organization Appellate Body have dealt with the concept of transparency. Fourth, it will endeavour to deduce a consistent basis in law for the awards discussed.

Interestingly, United States Federal courts and arbitrators do not refer to each other when discussing international customary law. It is unlikely that such learned jurists and arbitrators are unaware of what the other is saying. One might suspect that citing each other does not in their view add much to the definition of international customary law, at least in the area of law in dispute before that court or tribunal. Then again, it might be a struggle by the proponents of positivism showing deference to law-making bodies against international arbitrators who believe they have the authority and obligation to contribute to the …


Genetic heterogeneity can pose a challenge to identifying eligible cases for targeted therapy in the human epidermal growth factor receptor 2 (HER2) immunohistochemistry (IHC) 2+ breast carcinoma group. In this study, we characterised this subset of tumours according to clinicopathological parameters.


I was having a hard time figuring out how to begin when I came across an excerpt from an interview with my MIT colleague Professor Jay Forrester, who is either the Christopher Columbus or the Dr. Strangelove of this business, depending on how you look at it. Forrester said he would like to see about a hundred people, the most gifted and best qualified in the world, brought together in a team to make a psychosocial analysis of the problem of world equilibrium. He thought it would take about ten years. When he was asked to define the composition of his problem-solving group, Forrester said: "Above all it shouldn't be mostly made up of professors. One would include people who had been successful in their personal careers, whether in politics, business, or anywhere else. We should also need radical philosophers, but we should take care to keep out representatives of the social sciences. Such people always want to go to the bottom of a particular problem. What we want to look at are the problems caused by interactions."


As an important guarantee device for the safe operation of vehicles, the performance of vehicle brake directly affects the reliable operation of vehicles and the safety of drivers. Vehicle brakes mostly adopt the way of friction braking. In a vehicle braking system, brake pads are vulnerable and fail due to wear. Therefore, it is very important to study the reliability and life of brake pads for vehicle safety performance. The wear of brake pads relates to friction materials, the brake temperature, speed, brake disc material, manufacturing condition, the distributions of braking force and personal driving habits and so on. The reliability and life calculation for the brake pads is very difficult [3]. Many existing studies have analyzed the reliability of braking system. For example, Tu et al. established the fault tree of the air braking system using the fault tree analysis technique and reliability assessKeywords


In this study, we aimed to: i) determine the impact of three new isonicotinoyl hydrazones derivatives in in vitro systems used to investigate free radical processes - radical scavenging approach (ABTS and DPPH) and iron induced peroxidation in lipid containing model systems and ii) evaluate the potential of polysaccharide-based particles to act as protective carriers preserving the antioxidant activity (AOA) of the tested compounds. The tested compounds revealed excellent antioxidant effectiveness in the ABTS system. In the DPPH radical scavenging assay the compounds exhibited very weak or absence of AOA. The data from the iron induced peroxidation methods disclosed better antioxidant properties of the derivatives in the system containing egg yolk homogenate which is more plausible compared to the lecithin containing one. The incorporation of a bromine atom on 5th position in salicylaldehyde moiety is associated with diminishment of the radical scavenging activity in the systems containing stable free radicals but its AOA reduction after encapsulation during the storage was only 9.17%. The obtained data indicate that compounds have proven themselves as promising candidates for further evaluation as antioxidant agents. Their encapsulation in chitosan-alginate particles could be a useful approach for improving the stability of their antioxidant properties.


In order to end this confrontation and estrangement between the two sides of the Taiwan Strait and to achieve a strong and prosperous nation, the government of the Republic of China (ROC) has, since 1987, adopted concrete measures to promote social, cultural, and economic exchanges between the two sides of the Strait in a forward-looking, pragmatic, active, and moderate way. In February 1991, the ROC government drew upon the insight of people inside and outside the ruling party in drawing up the "Guidelines for National Unification," part of an attempt to form a national consensus for the advance toward unification.

This research focuses on customer-oriented lean innovation and introduces the innovation empathy framework that has been developed for the early phases of innovation processes. The framework is based on the idea that increased empathy towards customers helps innovators gain a better understanding of customers' problems and needs, and increases the possibilities to generate more value to the customers. The analysis of the test use of the framework with business managers illustrates how empathising, i.e., putting oneself in the role of the customer, can be rehearsed through empathising exercises and, more importantly, through empathetic facilitation.

Density functional theory calculations of the vibrational circular dichroism (VCD) spectra of a transition metal complex, (+)-tris(ethylenediaminato)cobalt(III) as a free ion and with associated chloride ions, are reported. By comparison with experimental data obtained in our laboratory in 1986 (Young et al. J. Am. Chem. Soc. 1986, 108, 7255) and new measurements, this study identifies, for the first time, the geometry and absolute configuration of the association complex as Λ-δδδ-Co(en)3Cl2+, in which two chloride ions each associate with three NH bonds along the C3-axis of a D3-symmetry complex. The DFT calculations, carried out with both the LanL2DZ and 6-31G(d)[C, H, N]/Stuttgart ECP [Co] basis sets, predict the energy order of ethylenediamine ring conformations as λλλ < λλδ < λδδ < δδδ for the free (gas phase) Λ-Co(en)33+ ion, an order opposite to that deduced from solution studies. The VCD studies identify the δ-conformation as the most prevalent in solution for halide and sulfate counterions, sugge...

The mental health of seafarers has become a growing issue of concern and has attracted the attention of researchers in recent times. Seafarers are predominantly men, spend months at sea with little to no contact with loved ones ashore, and usually must reside in confined spaces that often contain substantial levels of noise and heat. The underlying causes of mental illness among seafarers are known. Some of the causes include sleep deprivation, occupational stress, marital/relationship problems, fatigue, the threat of piracy, psychosocial workload, loneliness, social isolation, separation from families, lack of shore leave, cultural issues, and job security. Despite these stressors, there are many men and women seafarers who flourish in the industry and enjoy their careers. Very little research has been conducted into the well-being practices of those seafarers who enjoy high levels of well-being. This study explores the lived experiences of a group of seafarers with reportedly high levels of psychological well-being, as well as their experiences of workplace stressors and mental health interventions offered by the industry. This study is an interpretive phenomenological analysis, which is epistemologically underpinned by phenomenology, hermeneutics and idiography. Results revealed four focus areas: general lived experiences across two worlds and how this relates to identity, what seafarers with reportedly high levels of psychological well-being experience as stressors, well-being practices of these seafarers and how these seafarers experience and make sense of mental health interventions they have come across.
