From this condition, students are expected to be able to access teaching materials without limits.


In this study Interlocking nails were used in order to fixate the canine femoral fractures and to examine the effects of the implants on fracture healing, clinically and radipgraphically in 19 dogs. The material of the study consisted 19 dogs of medium-large size, which were brought to Ankara University, Faculty of Veterinary Medicine, Department of Orthopedics and Traumatology because of injuries due to various trauma and consequent diaphyseal femur fractures clinically and radiologically. Following general anaesthesia, the broken extremity was operated, a total of 20 interlocking pins of different sizes were placed. Among the pins used with an appropriate diameter and length, 10 were 8-199 mm, 4 were 8-185 mm, 2 were 8-172, 1 was 8-165, 2 were 6-172 mm and another was 6-160 mm, respectively. In order to lock these pins 46, 3.5 mm diameter screws, with different length were used. It was observed that 1 screw in proximal and 1 screw in distal region, didn't hold in the holes of the pins. Statical nailing was performed in all cases but one. Cases were clinically examined for weight bearing and extremity usage and radiologically, the callus tissue development was monitored. As a result; the idea was that interlocking nailing technique was on alternative to plates by creating enough rigidity, to fixate 1/3 diaphyseal femoral fractures in medium and medium-large breed dogs.


The technology of trusted systems has advanced very rapidly during the past five years. The development of standards and product evaluations has raised industries awareness of the governments needs for trusted systems. A major weakness of trusted systems is the lack of application capabilities. The Honeywell SCOMP system is the only one to achieve the highest rating from the National Computer Security Center. Honeywell Federal Systems Inc. has implemented an integrated office management system called the Secure Office Management System. This system provides an effective solution for an office which requires processing information of various security aspects. The security and office capabilities of the system are presented along with a scenario for its use.


The nucleotide-binding, leucine-rich-repeat-containing protein, NLRX1 is recognized as a host factor which promotes HIV-1 infection of myeloid cells by suppressing HIV-1 reverse transcribed DNA induced and STING-mediated innate immune response. However, the function of NLRX1 in HIV-1 infection of CD4 T cells, the major cells responsible for HIV-1 replication in vivo, is still unrevealed. Here we found NLRX1 still acted as a host factor required for HIV-1 infection of the human T cell line, primary CD4 T cells, and CD4 T cell-reconstituted humanized mice through a mechanism involved in cell intrinsic pathways but not innate immune cytokines. In the perspective of virology, we found NLRX1 facilitated both of the integration of HIV-1 cDNA and HIV-1 LTR-mediated viral gene transcription. By using SILAC-based quantitative proteomics, we characterized that HIV-1 infection-induced expression of genes involved in the electron transport chain (ETC) of mitochondria through an NLRX1 dependent mechanism. Consistent with the proteomics data, HIV-1 infection led to increased oxidative phosphorylation in Jurkat T cell line but not in the counterpart containing shRNAs against NLRX1. In addition, inhibition of oxidative phosphorylation by mitochondrial complex I inhibitors suppressed HIV-1 infection in Jurkat cells, while forcing expression of genes involved in ETC rescued the deficiency of HIV-1 replication in NLRX1-deficient cells. Importantly, treating humanized mice with FDA-approved drug, metformin which targets mitochondrial complex I, significantly reduced HIV-1 viral load. This study demonstrated the potential of targeting NLRX1 and applying metformin in suppressing HIV-1 replication in patients.


The translation of public health service handbook is featured with its own characters in terms of three forms of using of knowledge: subject research,terminology standardization,and cultural awareness rather than a linguistic communication activity.Through a case analysis of medical translation,it can be found that these three forms are integrated which indicates the complexity,flexibility and professionalism of medical translation.The author maintains that the use of knowledge in translation benefits translation in medical fields;it also offers a new dimension of studying the relevant theory regarding the relation between knowledge and language.


A Lagrangian based method is used to derive an analytical model for studying the dynamics of matter-wave bright soliton created in a harmonic potential which is attractive in the transverse direction and expulsive in the longitudinal direction. By means of sech trial functions and a Ritz optimization procedure, evolution equations are constructed for width, amplitude and nonlinear frequency chirp of the propagating soliton of the atomic condensate. Our equation for the width is an exact agreement with that of Carr and Castin, obtained by more detailed analysis. In agreement with the experiment of Paris group, the expulsive potential is found to cause the soliton to explode for N |as| = 0.98, N being the number of atoms in the condensate and as — the scattering length of the atom–atom interaction.


The factors affecting the performance of ejector suitable for aircraft cooling are investigated theoretically and experimentally. The investigation covers a range of shroud-to-nozzle diameter ratios from 1.1 to 1.6, of shroud lengths from 0.2 to 2.28 nozzle diameters, of secondary-to-primary weight-flow ratios from 0 to 0.12, and of ambient-to-nozzle pressure ratios from 0.7 to 0.06. The results of a simplified theoretical analysis based on each type of flow are in good agreement with those experimentally obtained.

Supplemental Digital Content is available in the text. Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy, but categorization is complicated by variability in grading systems and uncertain prognostic significance of MAML2 rearrangement. The aims of this study were to determine the prognostic significance of MEC grading systems and MAML2 rearrangement status. Fifty-three carcinomas originally diagnosed as MEC (45 primary; 8 recurrent) of major and minor salivary glands were graded according to modified Healey, Brandwein, AFIP, and Katabi systems. Fluorescence in situ hybridization for MAML2 rearrangement was performed. Clinical features and outcomes were recorded. Twenty-five (47%) carcinomas scored the same in all grading systems. The most common histologic feature leading to a diagnosis of intermediate grade was isolated solid growth. Brandwein assigned the highest percentage of high grade (29%) and AFIP the highest percentage of low grade (80%). MAML2 was rearranged in 37/46 (80%) cases. Forty-three (81%) were morphologically compatible with MEC, and these were more likely to be low-intermediate grade and MAML2-rearranged. Of primary carcinomas, 6 (13%) recurred. Statistically significant univariate risk factors for recurrence included non-MEC morphology, stage T4, and high Brandwein grade. Margin status, MAML2 rearrangement, and isolated solid growth were not predictive of recurrence. A binary grading system (Brandwein high vs. low-plus-intermediate) could be considered to better reflect biological behavior in MEC. Our study confirms that MAML2 wildtype tumors more likely represent high grade non-MECs, and prior studies demonstrating worse prognosis in MAML2-nonrearranged MECs may be diluted by high-grade non-MECs.

The germination vigor of soybean seeds, seedlings weight, and nodulation activity during the development of soybean-rhizobia symbiosis at the vegetative stages of plant growth under the influence of the exopolysaccharides (EPS) of nodule bacteria Bradyrhizobium japonicum 634b (microsymbiont of soybean), Bradyrhizobium japonicum 631 (microsymbiont of both soybean and lupine) and Bradyrhizobium sp. ( Lupinus ) 359a, 400 (microsymbionts of lupine, with dif-ferent nitrogen-fixing activities) were evaluated in laboratory and pot experiments. It was shown that microbe EPS had no significant stimulative effect on soybean seed germination and seedling development. The tendency of increasing germination vigor and seedling dry weight was observed while the EPS400 at concentration of 0.100 mg/ml was used. This may be due to carbohydrate biopolymer properties. The decrease in the amount of the extracellular polysaccharides to 0.025 mg/ml resulted in a reduction in the soybean seedling weight but it was not reliable. Rhizobial EPS stimulated nodulation of soybean at the two trifoliate leaf stage (V2) when they were applied to seedlings before inoculation with B. japonicum 634b. There was a tendency towards an increasing the number of root nodules at the three trifoliate leaf stage (V3) and also when the soybean seedlings were incubated with EPS and then inoculated with B. japonicum 631. Early root nodule formation was observed when soybean plants were treated by the EPS634 and EPS631 and then inoculated respectively with B. japonicum 634б and B. japonicum 631. There was no clear relationship between the specificity of rhizobial polysaccharides action on seed germination, seedlings development, nodule formation in the soybean— B. japonicum symbiosis and symbiotic properties of the strains, from what the EPS were obtained. However, there was some difference between the carbohydrate biopolymers in their action.

Abstract OWING to the economic importance of the egg-laying characteristic of the fowl much research has been published on the inheritance of those phenomena associated with reproduction and sexual development. However, comparatively little is known concerning the physiological processes involved in development and activity of the reproductive organs. A knowledge of these processes is essential to a thorough genetical study of the reproductive phenomena in birds. The researches reported were planned in order to obtain a method by which the bases of individual differences in gonadal function might be evaluated. It has been shown by previous workers (Allen, 1932, p. 778) that the pituitary body is chiefly responsible for the development of the immature gonad of the chicken and duckling. Jaap (1934) found that the testes of adult Mallard drakes may be caused to increase in size during the winter months by feeding desiccated thyroid. This increase is due presumably to . . .


Recently, Pb-free solder has been widely used in the electronics industry due to the worldwide increase in environmental awareness. However, Pb-free solder has the higher melting point, lower wettability and the formation of brittle metal compounds by Cu diffusion has reported. In addition, UBM which have good reliability for the Pb-free solder become very important. In particular, the electroless Ni-P/Au UBM is widely used due to the better wettability and diffusion prevention of Cu. The main objective of this study is to evaluate the creep property for the Pb-free solder joints with Ni-P/Au UBM.

Software Defined Radio (SDR) allows integrating different wireless communication standards such as GSM, Bluetooth, and ZigBee, using the same hardware. In this scenario the antenna should be able to operate at different frequency bands of the coexisting standards to maintain the SDR advantages and flexibility. This difficult task can be tackled through the use of matching networks (MN) circuits, which allow changing the antenna's resonance frequency, without requiring significant redesign of the SDR platform. However, is particularly difficult to find a set of good MN components values when it is required to operate at multiple frequency bands because it is necessary to relocate multiple frequency resonances. For this reason in this paper, a statistical methodology based on a Design of Experiments (DOE) is proposed to model the SDR system response for obtaining the design values of the MN components that effectively relocate the antenna frequency resonances. Also this proposal allows minimizing the number of circuit simulations and in consequence, the design time. The proposed methodology is applied to adjust the frequency resonances of a commercial antenna and SDR system and the obtained results are validated experimentally showing its effectivity.


As the field of bilingual acquisition has made significant advances in recent years, there has been a surge of interest in the acquisition of Chinese languages in bilingual and multilingual contexts. This article serves a dual purpose: (1) to discuss some theoretical and methodological issues in bilingual acquisition with special reference to Chinese languages as target languages in bilingual and multilingual contexts; and (2) to highlight the important contributions made by the five articles in this volume, with some commentary on the issues raised by each study.The five articles to be discussed present highly original and dynamic research involving the acquisition of a Chinese language in children acquiring two or more languages simul-taneously from birth. The children featured in these studies come from three very different speech communities: Hong Kong, Australia and Paraguay. In most cases, either Mandarin or Cantonese (referred to collectively as Chinese here) is paired with English, with one case study also involving Taiwanese and Spanish. The combination of a Chinese language with English or another European language (such as Spanish in the case of Paraguay) being acquired by children in childhood raises new and challenging questions about bilingual development.The diversity in the backgrounds of the children featured in this volume provides a window into the complexity of language acquisition across different bilingual and multilingual contexts. These studies provide important results that future work on bilingual development of a Chinese language will have to take into consideration. They are also valuable in contributing to the fast growing body of longitudinal corpus-based studies by expanding the empirical base of bilingual acquisition and addressing theoretical issues of interest to the field at large.


Population ageing causes one of the greatest challenges nowadays, namely the improvement of the health condition, independence, quality of life and life expectancy of the elderly. Systems based on Internet of Things and Big Data analytics are being increasingly used in order to improve the medical process in terms of both quality and duration. Population ageing has significant implications for healthcare for the elderly. Geriatric professionals can help older adults manage complex healthcare needs. Geriatric assessment helps diagnose medical conditions, develop treatment plans, coordinate care management and assess the need for long-term care. The healthcare professionals need to monitor and assess the health status of the elderly with tools, systems and technologies, to process the large amount of information involved in these activities and to provide additional data and recommendations for adjusting their medication and treatment. In this regard, we propose a platform that uses these technologies in order to predict the chronic deterioration of health status, both physical and mental, in elderly and to evaluate the impact that different physiological and ambient parameters have in the development of the disease.

Of the vast array of personal finance issues affecting consumers in recent years, two in particular have generated more column inches than most - the misselling of endowments and pensions. With the FSA handing out fines in excess of half a million pounds and insisting on firms pro-actively reviewing vast numbers of past cases, retail financial services firms must understand the complaints and compensation rules. "Complaints and Compensation: A Guide for the Financial Services Market" will examine the compliance and redress regime for misselling, administration and claims problems with a practical emphasis on complaint handling, borne of the author's experience as a consultant and trainer. It will serve as an easy to use guide to the complaints sourcebook for the smaller IFA. For larger firms and their professional advisors it will act as an effective reference book enabling the reader to rapidly refresh their understanding of the rules and "best practice" procedures. The FSA has started to take enforcement actions against firms that fail to handle complaints or to treat their customers fairly. Complaints and Compensation: A Guide for the Financial Services Market will ensure that you are not caught up in the fall-out from a variety of misselling and administration issues, or if you are, that you are in a sound position to handle the consequences.


: Ample evidence has suggested that extracellular α-synuclein aggregates would play key roles in the pathogenesis and progression of Parkinsonian disorders (PDs). In the present study, we investigated whether mesenchymal stem cells (MSCs) and their derived soluble factors could exert neuroprotective effects via proteolysis of extracellular α-synuclein. When preformed α-synuclein aggregates were incubated with MSC-conditioned medium, α-synuclein aggregates were disassembled, and insoluble and oligomeric forms of α-synuclein were markedly decreased, thus leading to a significant increase in neuronal viability. In an animal study, MSC or MSC-conditioned medium treatment decreased the expression of α-synuclein oligomers and the induction of pathogenic α-synuclein with an attenuation of apoptotic cell death signaling. Furthermore, we identified that matrix metalloproteinase-2 (MMP-2), a soluble factor derived from MSCs, played an important role in the degradation of extracellular α-synuclein. Our data demonstrated that MSCs and their derived MMP-2 exert neuroprotective properties through proteolysis of aggregated α-synuclein in PD-related microenvironments.

SIGNIFICANCE
Misfolded α-synuclein can be released from cells and transmitted from one brain area to others through cell-to-cell propagation in Parkinson's disease (PD). Therefore, extracellular α-synuclein aggregates would play key roles in the pathogenesis and progression of PD. Proteolysis is the protective mechanism by which mesenchymal stem cells (MSCs) exert neuroprotective properties through proteolysis of aggregated α-synuclein into soluble forms, which is the actual protective mechanism, and matrix metalloproteinase-2 is one of the MSC-derived soluble factors that cleaved preformed fibrils of α-synuclein. The data suggest that the disassembly of α-synuclein aggregation to control PD-related microenvironments using MSCs may have a significant impact on future PD treatment strategies.


Supercapacitors are gaining increasing attention for complementing or replacing batteries and they are highly desirable in applications where high power and long cycle life of energy storage devices are needed. Activated carbons (AC) are the most promising electrodes in the supercapacitor industry presenting the best performances/cost compromise. Recently, graphene, with a two dimensional carbon nanostructure, has emerged as a new class of promising electrode material in supercapacitors, due to its outstanding properties such as high electric conductivity, high surface area, good mechanical properties and chemical inertia. Among the various approaches to producing graphene materials, here we focus on reduced exfoliated graphene oxide (r-GO) derived from chemically synthesised graphene oxide (GO). However, the graphene materials prepared by either chemical or thermal reduction of the graphene oxide always exhibits a relatively low electrochemical performance due to the agglomeration of graphene sheets and does not reflect the intrinsic capacitance of an individual graphene nano-sheet. To exploit the potential electrochemical applications for graphene, a particularly attractive option is to design and develop composites of graphene with other materials. In this study, we present an approach to synthesize a composite of reduced graphene oxide (r-GO) with activated carbon and its use as an electrode material in supercapacitors. To the best of our knowledge, a few studies on the preparation of GO/AC composites have been reported so far. Graphene oxide was synthesised using vein graphite by a modified Hummers method and then mixed with activated carbon to prepare a homogeneous composite. The composite was thermally reduced to convert GO in to r-GO. The morphology and chemical structure of the materials were characterized by means of Electron microscopy, Raman spectroscopy, X-ray diffraction and Fourier Transform Infrared Spectroscopy. Thermal properties were investigated using Thermo Gravimetric Analysis. The electrochemical properties of as obtained composites with different mass ratios were investigated, together with their individual components (GO, r-GO and AC) for comparison. For electrochemical characterisation, two-electrode symmetrical supercapacitor cells were constructed and characterized by cyclic voltammetry and electrochemical impedance spectroscopy. Tetraethylammonium tetrafluoroborate (TEABF4) in Propylene Carbonate (PC) was used as the electrolyte. The CV curves were measured from 0 to 1 V with various scan rates ranging from 10 to 1000 mV s −1 and the CV data were used to calculate the specific capacitances of the electrodes. The results showed that the as-prepared composites exhibited an improved electrochemical performance as compared to pure r-GO or AC. This improvement can be attributed to the synergistic effect of AC and r-GO. The maximum specific capacitance observed for the r-GO/ AC composite was 115.6 F/g at a scan rate of 10 mV s -1 . The near-rectangular CV curves at ultrafast sweep rate of 1000 mV s -1 indicated very efficient charge transfer within the composite electrodes. The incorporation of rGO into AC, not only provides the vacancies to accommodate ions, but also forms a promising network structure to conductively bridge the spaces between the AC particles, which can facilitate rapid transport of the electrolyte ions within the electrode materials, leading to a high-rate performance of the supercapacitor. Within the composite, r-GO plays the role of both the binder and the conductive additive increasing the specific capacitance and the power density of the devices.


We compute the skewness $t_3$ and the corresponding hierarchical amplitude $T_3$ of the divergence of the velocity field for arbitrary non-Gaussian initial conditions. We find that $T_3$ qualitatively resembles the corresponding hierarchical amplitude for the density field, $S_3$, in that it contains a term proportional to the initial skewness, which decays inversely as the linear growth factor, plus a constant term which differs from the corresponding Gaussian term by a complex function of the initial three- and four- point functions. We extend the results for $S_3$ and $T_3$ with non-Gaussian initial conditions to evolved fields smoothed with a spherical tophat window function. We show that certain linear combinations, namely $S_3 + {1 \over 2} T_3$, $S_3 + T_3$, and $s_3 + t_3$, lead to expressions which are much simpler, for non-Gaussian initial conditions, than $S_3$ and $T_3$ (or $s_3$ and $t_3$) considered separately.


Objective: In this qualitative study, we investigate how lesbian couples experience and deal with the difference in genetic relatedness in their family. Background: Previous research showed that lesbian couples handle the difference with regard to genetic relatedness by, for instance, creating a narrative about physical resemblances or by focusing on the social bond and its influence on children. Methods: The findings are based on qualitative in-depth interviews with 10 lesbian couples who had at least one donor-conceived child aged 7–10. Results: The difference with regard to the genetic link brought up complex and context-specific experiences for these parents. Generally, the genetic link was described as irrelevant: equality between both parents was presented as a given. However, some experiences of difference due to the presence of one genetic link were found. In these accounts, the genetic link was described as a valuable extra that created an inequality between them as parents. Conclusion: The findings show that these mothers have a complex attitude towards genetic relatedness.


The meander‐type fish pass is a slotted fishway characterised by the exclusive use of rounded and smooth components. Due to the specific geometry and arrangement of the basins, which differ considerably from the conventional vertical slot pass, there are significantly different hydraulic conditions. The water flow is guided along the basin walls by means of a dominant main current while the water body is much calmer towards the centre of the basin, where very low flow velocities are found. A detailed assessment of the functionality is currently impossible due to the small number of surveys of fish passage hitherto carried out. However, considerable potential is indicated by the high passage rates at some sites and the lack of selectivity with regard to species and small fish, together with the design advantages and the adaptation possibilities after construction work is completed. In this study, we offer some recommendations for dimensioning to enable this potential to be exploited. These are oriented around recommendations for conventional vertical slot passes regarding basin size, flow depth and slot width. Due to the great potential of the meander‐type fish pass, it is desirable to construct still more individual pilot passes to implement comprehensive surveys of fish passage on a sound methodological basis.

The 2.5D approach is used to solve the dynamo model in the Boussinesq approximation. Thermal convection in a fast rotating spherical shell with a free-rotating inner core is considered. In all cases the inner core rotates slightly faster than the outer boundary of the shell. The presented dynamo model reverses regularly without any external impulse, and the generated magnetic 4eld has the typical dipole structure at the surface. However, the dipole is aligned rather with the equatorial plane and thus the model can be applied to magnetic 4elds of Neptune and Uranus. ? 2002 Elsevier Science Ltd. All rights reserved.


The contention of this paper is that, at the moment, the concept of CSR lacks a theory to give it clarity and direction in the corporate context, this makes it difficult for managers to know what to do, how far to go, and how to evaluate and account for the results they are achieving in their endeavours to implement CSR poli-cies. To come to grips with the CSR movement we need briefly to consider why the demand for CSR has arisen, how it manifests itself in business practice, and whether it can be understood in theoretical terms so that it could become institutionalised in an accountable way. A candidate theory of CSR is offered: the communitarian theory of corporate purpose is to, within and uphold-ing the rules of ethical business, produce the maximum sustainable value for stakeholders. The measure of this is profits for shareholders and deposits of social and natural capital for other stakeholders.IntroductionA new concept has arisen in business practice that we, in the business schools, have been striving to catch up with and are seeking to understand. The concept is Corporate Social Responsibility (CSR) this is the idea that companies should consider the interests of society and the natural environment when making decisions. CSR is now a well-known expression for what, in the recent past, has been a collection of different and yet related terms: cor-porate philanthropy, corporate citizenship, busi-ness ethics, stakeholding, community involvement, corporate responsibility, socially responsible invest-ment, sustainability, triple-bottom line, corporate accountability and corporate social performance. Some of these terms have a family resemblance to each other, but many of these expressions have other connotations as well. This lack of consensus has se-riously hampered theoretical development as well as research into the implications of these related poli-cies and practices. A great deal of imaginative, in-novative and energetic activity is taking place in the field of CSR all over the world and we, in the busi-


I. INTRODUCTION This Article suggests the beginning of a general theory of licensing systems. I use the word license to refer to legally meaningful approval offered or required relatively early in a system of social control or private agreement. The presence of a licensing apparatus has implications for other, related tools so that the presence of a certification requirement or permission component will draw attention to the larger system of controls or incentives in which it is embedded. Generally speaking, a control, or regulatory, system can focus on inputs or outputs, and inputs can be examined from an ex ante-"upfront"-or ex post-"outcome-oriented"-vantage point. Thus, a negligence rule can normally be thought of as focusing on inputs from an ex post perspective, because it awaits an accident, or loss measured from some baseline, before asking about the character of the activity that caused this loss and the untaken precautions that might have averted the loss. Some strict liability systems can be thought of as geared to outputs and from an ex post perspective, because actors pay according to the injuries they actually cause. In turn, most (of what I will call) licensing systems pay considerable attention to inputs from an ex ante perspective. For example, one might need a license to operate a motor vehicle, market a drug, or search private premises. A general theory of licensing needs to grapple with (at least) three questions that reappear in disparate contexts: When are licensing techniques likely to be superior, in either functional or evolutionary terms? When should-or will-licensing requirements squeeze out seemingly duplicative, alternative means of social control? When should-or might-licensing be privatized as, for example, by the simple requirement that an actor be bonded by a private insurer who, in turn, would be free, with some enforcement help from the state, to set requirements for insurability? Market forces can be liberated in other ways as well. Thus, many licensing schemes raise the question of whether improvement is possible by simply permitting private parties to pay for speedier regulatory service. My intuition is that these questions benefit from a substantial dose of public choice theory, combined with considerations usually associated with work on deterrence and transaction costs.1 My focus in this Article, however, is not on these general questions about licensing, but rather on the disclosure element in licensing, or permission, schemes. The present Article does deal with the familiar problem of the consequences of a failure to comply with licensing requirements. The examples it I use raise questions about information and disclosure, and are selected in part to encourage an expansive conception of licensing. In addition to emphasizing this conception, or variety of licensing, I suggest that less information can sometimes be better than more. More specifically, I develop two ideas: first, in some settings the withholding of information might generate superior, unbiased licensing judgments and, second, the law might reflect some sensitivity to the likelihood that revelations are socially harmful. Lurking in the background of this examination is the hope that analysis of these specific points can begin to illuminate the grander questions regarding licensing schemes. Part II begins with some rules governing corporate fiduciaries. Al though the discussion might stand on its own, as a kind of old-fashioned case commentary or collection of ideas for classroom lectures on the subjects of corporate opportunities and self-interested transactions on the part of fiduciaries, I hope to show a number of interesting connections to licensing problems more generally. There is often an opportunity for fiduciaries to obtain consent, or a license, before investing or transacting in a way that is likely to lead to later conflict. The comparison between this private, or contractual sort of permission, or even ex ante regulation of an agent, and a more conventional licensing system, organized by a regulatory authority and often bounded by legislatively drawn categories and requirements, may seem far-fetched at the outset, but it offers a useful way to get at some of the complexities associated with licensing. …


A survey of the development of the application of quantum chemical techniques to Ziegler–Natta polymerization starting from the pioneering work of Clementi and co-workers is presented. In the latter, the role of the catalyst was elucidated, a feasible reaction pathway was proposed, and several properties of the catalyzed reaction (heats of formation, activation barriers, physisorption and chemisorption energies, etc.) were obtained without semiempirical approximations. Furthermore, a few proposals for enhancing catalytic activity for the oligomerization process proved to be of great practical value and led to several patents. This turns out to be a good example of the usefulness of the computational techniques to provide intense interactions between theoretical and applied chemistry.


the Nicene cause (61). The second aspect of Ephrem's anti-Jewish rhetoric is his construction of scriptural genealogies to support his claims. One lineage begins with the disobedient "People" who worshipped the golden calf, were accused by the prophets, and rejected by God at the crucifixion. The other genealogy, stemming from Moses, traces through a faithful remnant and culminated in Jesus, through whom the covenant was passed to the Gentile "peoples." The genealogical aspect then enables the third, namely, that Ephrem could apply his anti-Jewish arguments also to Christian "Arians." (S. nuances the term "Arian" by noting Ephrem's main subordinationist opponents were likely influenced by Aetius). The "Arians" followed in the lineage of the "People"; Ephrem called them "Pharisees" because of their "searching" inquiries that led them to their suborinationist beliefs, and he accused them of crucifying the Son through their written tracts. Ephrem's scriptural "history" thus provided a picture of Judaism unlike that of contemporary Jews, which he transposed onto "Arians," rhetorically fusing together Jews and "Arians" as "other" than Nicene Christian. To complete her argument, S. places Ephrem into the broader fourth-century pro-Nicene debate by demonstrating that Athanasius and the Cappadocians also "conflated" Jews with "Arians," especially in the accusation that both groups subordinate the Son to the Father. There is little constructive criticism to offer such a well thought through work. Although S.'s main ideological argument is somewhat repetitive, this helps the grasping of the entire argument from only a single chapter. Perhaps S.'s use of "rhetoric" could have been more intentional. Most often it is used in the modern sense to refer to a kind of language. Yet, what might her study contribute to what we know of rhetorical technique employed in the fourth-century? S.'s work has relevance for a broad range of interests in Christianity of the late antique world, be they social, political, or theological; indeed, she confirms the inseparability of these aspects. In terms of Syriac studies, not only does S. place Ephrem more concretely into the fourthcentury Roman world, but her work is exemplary also in her clear use of method while not compromising on close engagement with the text.


Objective To investigate the effect of different starting times of gonadotrophin(Gn)on the outcomes of in vitro fertilization-embryo transfer(IVF-ET).Methods A total of 79 infertile patients underwent ovarian stimulation of prolonged down-regulation protocol for IVF-ET was divided into groups of A(39cases,recovery time of pituitary≥18d)and B(40cases,recovery time of pituitary18d)according to recovery time of pituitary after final GnRHa injection,or groups of C(40cases,LH≥0.5U/L)and D(39cases,LH0.5U/L)according to LH level on the starting day of Gn.The clinical and laboratory results and outcomes of pregnancy were compared among those groups.Results Compared with group B,the total dosage of GnRHa,duration and total dosage of Gn use were decreased,while E2 level on the starting day of Gn and implantation rate were increased in group A(P0.05).Compared with group D,the total dosage of GnRHa,duration of Gn use and starting dosage of Gn were decreased,while the recovery time of pituitary,E2 level on the injection day of HCG and clinical pregnancy rate were increased in group C(P0.05).Conclusion The delayed recovery time of pituitary after prolonged down-regulation is beneficial for increasing LH level,decreasing the duration and dosage of Gn,reducing economic burden,and enhancing clinical pregnancy rate of IVF-ET.

Pneumoencephalography (PEG) was carried out in 50 patients of both sexes consecutively discharged from a psychiatric department with a diagnosis of acute schizophrenia. At clinical follow‐up with a mean observation time of 8 years the diagnosis was verified in 38 patients, while 12 were considered to have had a reactive psychosis. The PEG findings and clinical findings in these two groups are compared, and compared to corresponding findings in 101 chronic schizophrenics previously studied with the same method.

The increasing demand for system miniaturization and high power density energy produces excessive thermal loads on electronic devices with significant mechanical strain. Carbon Nanotubes (CNTs) based devices are found to have excellent thermal transport properties that makes them attractive for thermal management of these miniaturized nano-electronic devices under extreme environments. These conductive nanostructure (carbon nanotubes, graphene, etc.) are often embedded in polymers or other high-strain alloys (the matrix phase), and are used as bridging materials for conductivity (electrical and thermal) with strain resiliency. The effect of strain on the thermal transport properties of these nanostructures have often been overlooked and will be the focus of this work. The thermal conductivity of the nanostructure is obtained in LAMMPS using the Heat-Bath method, which is a reverse non-equilibrium molecular dynamics (RNEMD) simulation strategy. In RNEMD, constant amount of heat is added to and removed from hot and cold regions and the resultant temperature gradient is measured. The effect of strain on the thermal conductivity of the single and multiwalled nanostructures of various configurations will be discussed with specific emphasis on the phonon density of states of nanotubes at different strain states.


There is current interest in the toxicity associated with formaldehyde and its role in biological systems in view of its increasing use. The oxidation of formaldehyde to formate proceeds mainly via two pathways, one involving the low K , mitochondria1 aldehyde dehydrogenase and the other a glutathione-dependent cytosolic aldehyde dehydrogenase, specific for formaldehyde.' Previous experimen t~~ ' showed that oxidation of exogenous formaldehyde by the glutathionedependent formaldehyde dehydrogenase was not affected by cyanamide, a potent inhibitor of aldehyde dehydrogenase. By contrast, cyanamide inhibited the oxidation of formaldehyde by rat liver mitochondria by 75 to 90%. In isolated hepatocytes, cyanamide inhibited the uptake of formaldehyde as well as the production of C02 and formate by approximately 50%. These results indicated that formaldehyde can be oxidized by cyanamide-sensitive, presumably low K, aldehyde dehydrogenase, and cyanamide-insensitive, formaldehyde dehydrogenase reactions. The experiments described in this report were carried out to investigate the metabolism of formaldehyde generated by the oxidative demethylation of aminopyrine by the cytochrome P-450-dependent monooxygenase system. Measurements of ''TO2 production after administration of labeled aminopyrine to humans or animals is used as a liver function test4 and applied for the diagnosis of liver diseases.s

The quality of theories produced with the help of machine learning algorithms is usually measured in terms of accuracy and coverage. This paper reopens the issue of understandability of induced theories, which, while prominent in the early days of ML, seems to have fallen from favor in the sequel. The guiding question is: beyond accuracy, what constitutes a good theory? An attempt at surveying relevant work in the elds of linguistics and cognitive psychology is made. The sympathetic reader will nd this somewhat motivates the author's personal intuitions about the quality of a theory, hinging on understandability. These intuitions, in turn, point toward some simple criteria that may help in measuring quality. By way of consolation for those who do not share the author's intuitions, the criteria proposed here are objective in the sense that the measurements they provide may be evaluated from a number of contrary perspectives. Some empirical results are given in the context of theory restructuring.


For the multidimensional Dirichlet problem of the Poisson equation on an arbitrary compact domain, this study examines convergence properties with rates of approximate solutions, obtained by a standard difference scheme over inscribed uniform grids. Sharp quantitative estimates are given by the use of second moduli of continuity of the second single partial derivatives of the exact solution. This is achieved by employing the probabilistic method of simple random walk


The ecological system is a very complex system; many ecological theorical problems are (based) on niche and community. This paper considers niche and community as a dissipative structure and finds out link of basement between fuzzy mathematics and ecological system. At the same time, it gives dynamic fuzzy model of niche and community.Owing to the requirements of existence,evolution and development, the tendency to preference choice for optimum resources often results in (competition.) This paper discusses the relationships among the mutual benefit, Coexistence and (competitions) in the three dimensional fuzzy set. By fuzzy theory and system fuzzy analysis, fuzzy (sets,) of resources, pitch and time, a fuzzy model for competion is given.


The question of how to 'deal' with the past in post‐conflict Northern Ireland preoccupies public conversation precisely because it separates a violent history from a fragile peace and an uncertain future. After a brief examination of contemporary Northern Ireland's culture of remembrance, this article provides some analysis of the potentials and dangers of efforts to confront the legacies of the Troubles. I argue here that the challenge for post‐conflict heritage work in Northern Ireland lies in forging practices that permit and facilitate different ways of encountering complex and contradictory histories. These new efforts to remember encourage citizens to incorporate disparate, often conflicting memories into a patchwork of collected memory. Through a presentation of two case studies, this article offers an analysis of this memory work in an effort to show that it is as difficult as it is necessary. By forging a new tradition in memory work that transcends the long history of dual narratives and begins to make space for broader, more complicated engagements with the past, citizens are building their capacity to acknowledge, understand and respect difference. This opens up new conceptions of heritage that accommodate the incalculable complexity that accompanies reckoning with social and cultural inheritances. In settings in which the past is negotiated by ordinary citizens, heritage simultaneously demands and creates new spaces for public discourse.


In this paper, the novel 4H-SiC junction barrier Schottky diodes(JBS) were designed and discussed in our research group. Quasi-super junction JBS diode has good forward characteristic which is same with the conventional JBS diode. When the quasi-super junction JBS diode reaches the breakdown voltage in reverse operation, the electric field distribution in the active region is uniform, and the electric field at edge termination can be effectively spread out. In addition, the breakdown voltage of quasi-super junction JBS is higher than that in the conventional design. In our design, the quasi-super junction 4H-SiC JBS dose not have to process with multi epi and trench. Therefore, it can be fabricated by the same method as the conventional JBS diode.


In England women are favored—because of their special qualifications for the work—in making appointments as housing managers for the numerous projects of varied type, private and public, in the field of slum clearance and "model homes" administration. They are required to have the spirit and training of social workers, plus training and ability in business. Special training facilities for this growing profession are provided. The author of the following article believes that in this country there is likely to be a rapid development of opportunities for women in housing management. Steps are already being taken by the National Association of Housing Officials, in cooperation with the Federal Housing Administration, to provide the necessary training facilities.


found that any carcmioma has taken up 18t, We have come to rely on surgery and dep X-ray therapy, since we have found that an anaplastic undifferentiated growth which does not take up 1311 usually is sensitive to deep X-ray therapy. The size and scope of the surgical operation must be planned in the light of personal experience of the results of operation. I do not believe in large mutilating operations involving resection of larynx, trachea or esophagus. This belief has been arrived at during the course of the'past ten years, after much consultation with Dr. Phyllis Wade, the head of our Radiotherapy Department. Mr. C. Joll was always very much against doing a tracheotomy during operation because of the danger of aspiration pneumonia. Quite frequently one may find the growth adherent to the trachea or cesophagus. In my opinion it is wise to leave a small piece of growth on an intact viscus, to be dealt with by radiotherapy. I know that this statement is in direct opposition to the ordinary surgical treatment of cancer in which the growth is removed with an area of normal tissue round it. I strongly believe in avoiding injury to both recurrent laryngeal nerves; if one is already paralysed I scrupulously safeguard the other one. Injury to both nerves means a tracheotomy and, in a high percentage of cases, death from bronchopneumonia. I think cervical nodes should be removed in a case of malignancy, but that it is not necessary to do block dissection as for carcinoma of the tongue, with removal of sternomastoid and the internal jugular veins. I believe that in every case a total or near-total thyroidectomy should be done, with clearance of lower deep cervical nodes. Any small piece of growth adherent to trachea, cesophagus, and recurrent laryngeal nerves should be left in situ. Dr. Wade irradiates those patients in whom I have had to leave any of the growth behind. The small volume of growth she has to destroy reduces the dosage and the reaction. The results of this form of combined surgical and radiotherapeutic treatment must be sufficiently good to justify its use, and we are getting promising results This group consists of 17 cases which I do not think were curable by surgery alone, because at the time of operation the growth was already invading trachea, aesophagus, skin, strap muscles or recurrent laryngeal nerves. In every case I attempted a total thyroidectomy with removal of glands (but not a classical block dissection with removal of sternomastoid muscles and the internal jugular vein). The small portion of growth invading an important structure was left behind. None of these cases needed a tracheotomy and all swallowed normally after operation. The post-operative incidence of tetany is low, but should always be watched for, closely. Cramps in the hands and feet can be relieved almost instantaneously by an intravenous injection of calcium gluconate, and thereafter the condition is treated by oral calcium gluconate, and calciferol until the calcium metabolism becomes stabilised. As soon as the wound had healed all patients had a full course of radiotherapy, going on to the stage of moist desquamation of skin, increased hoarseness and difficulty in swallowing. After recovery from this combined treatment they have been followed up for periods of one to eight years and have been treated where necessary for myxcedema. So far we have had one death from recurrence and four deaths from other causes.


Spring is here and, not surprisingly, diesel prices are trending upward. Taking time to implement a few simple management techniques can reduce farm fuel consumption and keep machinery running smoothly.


Introduction ─ Multidrug-resistant tuberculosis is resistant to isoniazid and/or rifampicin. It is favored by poverty and infection with the human immunodeficiency virus. This retrospective, descriptive study aimed to determine the contribution of Xpert MTB/RIF® in the diagnosis of multidrug-resistant pulmonary tuberculosis in a semi-urban environment at the Peace Hospital of Ziguinchor in Senegal during the period from April 2015 to August 2019.Methodology ─ The study is retrospective, descriptive and carried out in the laboratory of Ziguinchor Hospital de la Paix, in southern Senegal, from April 2015 to August 2019. All respiratory specimens were subjected to Ziehl-Neelsen-stained smear microscopy and Xpert MTB/RIF® testing.Results ─ 180 samples, i.e. 6.4% were microscopy-negative but positive in Xpert MTB/RIF® testing. 32 patients (1%) are infected with rifampicin-resistant M. tuberculosis, against 29% of patients (798/2794) infected with susceptible strains.Conclusion ─ Tuberculosis is not longer a "disease of the past". Having a high cost, Xpert MTB/RIF® testing must be associated with microscopy, which remains accessible in semi-urban areas and is easy to perform.


We here report on the identification of a novel human EGF‐TM7 receptor, designated EMR4. Like most EGF‐TM7 receptor genes, EMR4 is localized on the short arm of chromosome 19, in close proximity to EMR1. Remarkably, due to a one‐nucleotide deletion in exon 8, translation of human EMR4 would result in a truncated 232‐amino acid protein lacking the entire seven‐span transmembrane region. This deletion is not present in nonhuman primates, including chimpanzees, suggesting that EMR4 became nonfunctional only after human speciation, about five million years ago. Thus, EMR4 surprisingly accounts for a genetic difference between humans and primates related to immunity.

The Alaska Volcano Observatory (AVO) uses an informal set of names for about 140 'volcanoes.' Some names refer to large, complex volcanic centers, while others indicate only a specific cone. This publication expands the list of 140 named volcanoes to include all volcanic vents where magma has reached the surface over the past 2.6 million years. This database of all known (published, or unpublished with permission) Quaternary volcanic vents was developed to better describe the nature and character of Quaternary volcanism in Alaska and specifically to aid in the discussion of spatial and temporal patterns of Alaska volcanism. This list is a preliminary starting point, and we hope that it is updated and expanded by the addition of newly discovered subaerial and submarine vents. We invite the community of volcanologists who study Alaska volcanism to help us develop this database by adding new vents as they are discovered and by improving the geologic descriptions of known vents as new information becomes available.


Objective To explore clinical value of left ventricular(LV) epicardial lead implanted by thoracotomy in cardiac resynchronization therapy(CRT) of chronic congestive heart failure. Methods LV epicardial leads were implanted by thoracotomy in a patient after failed coronary sinus implantation for abnormal ostium of coronary sinus. Results Right atrial and ventricular endocardial leads and two LV epicardial leads were implanted successfully without any serious complication. Pacing threshold of the epicardial leads decreased from 2.0V during operation to 0.5V at third day post operation. Clinical symptoms improved gradually, NYHA functional class reduced from Ⅲ~Ⅳ to Ⅱ, LV diastolic diameter decreased from 72mm to 66mm, and dyssynchrony between interseptal base and LV lateral wall ameliorated under optimum pacing parameters two weeks later. Tissue Doppler image displayed resynchronization of LV contraction during 12 weeks follow-up. Conclusion LV epicardial lead implanted by thoracotomy is safe and feasible in CRT after failed transvenous approach. LV epicardial lead positioning during operation and rational management after operation is very important.


Chemical analysis is part of chemistry that concern on sensor of material. There was develop some method in analytical chemistry. Spectrophotometry method was develop early. The some new method was develop in the 2000 century. One of the method is electrochemistry. Electrochemistry has been used for chemical analysis in multiple fields through electroanalytical techniques. Electroanalytical techniques are prominent analytical technique due to high sensitivity, reduction in solvent and sample consumption, high-speed analysis and low operating cost. A review of the electroanalytical techniques, namely, potentiometry, cyclic, differential pulse, square wave and stripping voltametric techniques, are reported. This review gives application of different electroanalytical techniques in chemical analysis.


The driving factors of innovation in the Italian food sector could be identified either in internal and in external dynamics. On one hand, the responses to the competition with new actors coming from emerging countries and the reaction to high-tech products demand evolution. On the other hand, endogenous dynamics appear to become more important for the strategic behaviour of the firms: a higher qualification of the human capital, a more clear orientation for high quality products, organization changes, and relation capacity development. Starting from these considerations, this paper developed an econometric analysis using information from one of the most important national dataset for innovation analysis. The results pointed out that a determinant to successfully develop and introduce product innovation is the capacity to built relationships on the product markets (i.e., with the modern distribution), while the territorial context determines a higher/lower relevance of each of the driving factors of innovation.

Recommending positions for civil servants efficiently, scientifically, and accurately has always been an urgent need for government departments in personnel management. However, most of the existing position recommendation algorithms do not use the sequence information in the historical working experience of civil servants; and only use collaborative filtering or features for the recommendation. Our motivation is to solve the shortcomings of existing position recommendation algorithms and realize efficient and accurate recommendations. Therefore, we propose a model fusion recommendation algorithm based on sequence, effectively fusing sequence and feature information. We use SR-GNN (Session-based Recommendation with Graph Neural Networks) as our base learner to learn sequence information, and we also use logistic regression, Xgboost, LightGBM as our base learners to learn feature information. Finally, Xgboost is used as our meta learner to fuse the output of our base learner. Experiments on the open civil servant resume data set show that our method has achieved better results than the original sub learner.


Personalized and adaptive learning environments (PALE) offer benefits for workplace learning because they can account for individual needs and constantly changing work requirements. Yet, the identification of reliable indicators for supporting trusted PALE remains a major challenge. This systematic review provides an overview of empirically investigated indicators of the learning context. Out of an initial set of 28,782 publications, a final sample of 273 key publications was identified, according to predefined inclusion criteria. The synthesis yielded 208 indicators of the learning context that were clustered into 26 dimensions. The findings show that the learning context has been associated with learning processes and outcomes in numerous included studies and should therefore be considered when designing PALE. Future research shall detect the most relevant indicators as well as design and evaluate specific learning interventions based on these indicators.


Indonesia and Malaysia are two countries in Southeast Asia that are always included in the top ten countries in the world that have the health and development of Islamic Finance according to the State of The Global Islamic Economy (GEI) Report. This study analyzes the performance of Indonesian sharia stocks that are incorporated in the Jakarta Islamic Index (JII) and Malaysian Islamic stocks that are incorporated in the FTSE Bursa Malaysia Hijrah Shariah Index (FHSI) for the period 2011-2018 with a technical analysis approach using 4 indicators, namely: return, volatility, Value at Risk (VaR), and Modified Sharpe Ratio (MSR). The results obtained from this study are that there have no significant differences in return and MSR performance between Indonesian and Malaysian Islamic stocks, but there have differences in volatility and VaR, where Indonesian Islamic stocks have higher volatility and VaR than Malaysia at a 95% confidence level.


Ultrathin inorganic nanowires are an emerging class of building blocks for creating functional materials and devices, but there remains challenging to fine‐tune the structure and property of the nanowires at the molecular level. Here, this work shows that ultrathin polymer‐grafted gold nanowires (PG‐AuNWs) can exhibit bottlebrush polymer‐like physical behaviors and macroscopic properties. The hybrid PG‐AuNWs in solutions show polymer‐like viscoelasticity which can be finely regulated by controlling the structural parameters (e.g., length of the AuNWs, molecular weight of grafted polymers) of the PG‐AuNWs, the environmental conditions (e.g., temperature, solvent compositions), and the aging time. Furthermore, this work unravels at the molecular level that the conformational properties (e.g., contour length, persistence length, and mean‐squared radius of gyration) of the PG‐AuNWs can be correlated to their structural parameters following similar power‐law relations as molecular bottlebrush polymers. This work bridges the fundamental gap between polymer‐like inorganic nanowires and bottlebrush polymers, thus accelerating the development of new nanowire‐based functional hybrid materials and devices.


NASA's Imaging X-ray Polarimetry Explorer (IXPE) was launched in December 2021. It is 100 times more sensitive to polarized X-ray emission than any preceding mission and it is opening a new observational window into high-energy astrophysics. I outline Yury N. Gnedin's many contributions to understanding polarization from neutron stars and present new simulations of observations that IXPE will perform of the X-ray pulsar Hercules X-1 and the magnetar 4U 0141+561 in February 2022. These observations highlight and test particular models that Gnedin and collaborators first proposed. I outline how IXPE will provide unique constraints on the structure and kinematics of the boundary region between the accretion flow and the neutron star surface of Hercules X-1 and how IXPE will verify the predictions of vacuum birefringence for the magnetar 4U 0142+561.


"Kage no Sekai" is an interactive content. It makes us able to communicate through the actual shadow with the marvelous creatures; that we can see when we look in the shadow. The world, which we can see when we look in to the shadow of the objects on the table, is making their own world view that we won't usually find out. Users can communicate with the world of shadow by approaching to the space or, by using a shadow made by putting an object or, changing the shadow's shape by moving the object's direction or their own shadow.


Anesthesiologists often encounter cases where both the intravenous catheter and blood pressure cuff are placed on the same arm. When the blood pressure cuff inflates, it usually causes retrograde flow of blood into the intravenous infusion line, sometimes up to the infusion chamber. To avoid backup of blood, a simple method was previously recommended (1,2). However, this method is unsuccessful in some cases. Thus, we modified this method to increase the success rate. A stylet (FUJI System, Tokyo, Japan) is coiled twice around a laryngoscope handle to form a spiral before use (Figure 1). The stopper of the stylet is removed. The infusion line is placed between the two turns of the coil (Figure 2). The device is then sandwiched between Velcro layers. The remaining portion of the stylet is bent for the safety of patients and medical staff. We checked


As part of an exchange on the financial crisis generated from a roundtable discussion at the University of North Carolina School of Law, this commentary observes the sharp shift in public discourse on, and regulatory interest in, the federal bankruptcy system, financially distressed homeowners, and judicial discretion, presumably brought about by the changed financial climate. That shift is reflected in stark differences between the 2005 amendments to the Bankruptcy Code (BAPCPA) and pending proposals to enable home mortgage modification in chapter 13 bankruptcy cases. I identify several challenges associated with using bankruptcy law to pursue current housing and economic policy goals and offer suggestions on how to manage those challenges, including the repeal of BAPCPA.


Concerns are being raised about the 'behaviour and attitudes' section of the new Ofsted framework as it does not seem to share the early years sector's interpretation of self regulation.


A P20 steel are machined in the milling speed range of 200 to 942m/min. The morphology and formation of the chips are investigated at various speeds. The serrated chips with adiabatic shear band are observed at a high milling speed. The transition from continuous to serrated chip formation is favored by the increase in work material hardness and milling speed. The study assumes that the chip segmentation is only induced by adiabatic shear banding, without material failure in the primary shear zone. Based on adiabatic shear theory, using the JC and the power material constitutive equation, the modified material model which takes into a strain softening is developed for prediction of the serrated chip formation. Experimental measurements are compared with the simulation results.


The ultimate goal of patent systems is to introduce the public about new ideas and technologies through the publication of patents. The inventions of patentable quality are what the patent systems is trying to encourage. At the same time, as it has shown by the patenting history, guaranteeing patentable quality of inventions has been and is to date widely debatable and conjointly costly. The reason for this -- intellectual and intangible nature of the invention and as a result, any satisfactory legal definition of the invention, not mention the patentable one, has ever appeared. Such long time legal uncertainty in patent systems looks incredible. How is it still possible that so many parties involved in patent enforcement and prosecution issues find it possible to apply the legally undefined concept of invention, without noticing the obvious unfairness? I probably know the answer: the background of information in patenting has been and is so far "sickly�?. As it turns out in the present article the main problem the patent systems encounter is that the efforts to define the invention has been controversial. Namely, participants in patent systems have not come to agreement what is novel in the patentable invention, whether the inventive idea or its practical application, i.e. its physical embodiment. Undoubtedly, if to take into account the conception of 'intellectual property' (see WIPO's Intellectual Property Handbook) and the factual knowledge that virtually in patenting all inventions can be understood as improvements of prior art, then the real patentable invention signifies underlying unique information representing a new inventive idea in the inventor's head. Indeed the solution of concrete technical problem in an inventive process identifies de facto this new inventive idea and I find in all seriousness that mentioned information in accordance with the problem-solution paradigm should definitely be reflected from the independent patent claim coinciding with the legal definition of concrete patentable invention. In the said light I am sure that the patent claim, as the heart of a patent and defining the limits of exactly what the patent does, and does not cover, is supposed to be precise, succinct, and without from superfluous descriptive and contextual material so that readers can more easily identify and understand essence of the invention. Thus the patent claim should be only one sentence long and to determine more specifically the legal definition of the concrete patentable invention. It means, we should not continue to tolerate the situation, where the patent claims have time criticized as vague (not clearly or fully explained), unreadable (very difficult to read), excessively (much more than is reasonable) long, impossible (extremely difficult) to search, and dreadful (very unpleasant) to interpret. My understandings in the present article "Bottlenecks of the patent systems�? will give opportunity to prevent mentioned criticism if we will at that follow decisively by the intrinsic principles of intellectual property and of patentable invention, which you should admit, have not been intelligibly implemented yet in patent systems. After all you cannot reasonably have a test where the core concepts -- invention as well as patentable one, used to evaluate patenting, yourselves are legally undefined.


A source-and-sink method has been developed for the solution of both ablation and combination of ablation and Stefan problems for a one-dimensional, subcooled medium imposed with both constant and time variant heat flux conditions. In this method the problem is solved in a fixed domain, so that the original heat flux condition imposed on the moving boundary is taken to be the condition imposed on the solid-vapor or liquid-vapor interface. This flux condition can then be used together with the temperature at the interface to solve for the interface position as well as the condition imposed on the fixed boundary. Finally, these interface position and boundary conditions are used in the temperature equation to complete the solution. The method has been used successfully in solving seven examples encompassing one-, two-, and three-phase ablation with the boundary of the medium imposed with constant, linear, and quadratic flux conditions. Numerical solutions for these examples as well as the trends of the moving boundary positions are discussed in detail.


The board of Indonesia Accounting Standard published SAK EMKM for effective per 1 January 2018. It is becoming the framework in preparing financial statements based EMKM. Its purpose is addressed to perpetrators of SMEs in order to be more comprehensive to prepare independently financial statements so the access to obtain the finance is easier. A workshop was conducted for 2 days in this community service. The perpetrators of SMEs did the practice of preparing statements based on business transaction integrated with tax reporting. The subject of training consisted of 27 SMEs distributed at South Sulawesi. In this training, academics, practitioners, and member of the Indonesia Accountant Institute were involved.  After it finished, the process of guidance was conducted so subjects can be evaluated in preparing financial statemens. One of the subjects of the evaluation was UKM Hidayat with its business of Abon Telor. In its financial statements, income and financial position statement were prepared.


The biological material was represented by ten local tomatoes populations collected from areas with saline soils from Moldavia region and compared with commercial type salt-tolerant tomato Determination of photosynthetic pigments of leaves was done by the spectrophotometric method. For determination of photosynthetic pigments of leaves we used a UV spectrophotometer type – 1800. The content of chlorophyll pigments was assessed by light absorption ability of the acetone extract of pigments (1%) in the visible spectrum (400-700 nm). Tomato genotypes in the study were subjected to salt stress for a period of 30 days is constantly wetted with saline solution to a concentration of 100 mM and 200 mM. The pigment content was analyzed at 15 days and 30 days after the saline treatment. After 15 days when the tomato genotypes was subjected to constant stress salt the content of chlorophyll a 662-663 chlorophyll a 431-432 , chlorophyll b 453-454 and chlorophyll b 616-617 showed higher values compared with analyzes performed after 30 days. Analyzed the results based on biphasic model of growth response under salt stress proposed by Munns (1993), and found that tomatoes reacted similarly. The transition from phase I (osmotic stress) to phase II (ions toxicity), is done by salt stress intensity, but mostly by cultivated genotype.


The present invention relates to a method for estimating the voltage of a sub module of a modular multi-level converter which includes a plurality of arms composed of a plurality of sub modules of which the output is variable depending on the operation of a switch included inside. The method includes: a step of inputting a certain voltage command to the arm and measuring the voltage between two ends of the arm at each of a plurality of predefined sensing time points according to the voltage command; a step of calculating the switching change amount of each sub module based on the switching status information indicating the on/off status of a switch included in the sub module included in the arm at each of the time point before a certain point of time and after a certain point of time based on the plurality of the sensing time points; a step of calculating the arm voltage change amount of each sub module based on the calculated switching change amount; and a step of, if the switching change amount in a certain time period is not a predefined threshold, estimating the voltage value of the sub module corresponding to the switching change amount based on the arm voltage change amount in the time period. By measuring the voltage between the two ends of an arm and estimating the voltage of each of the plurality of the sub modules included in the arm, the present invention does not require many voltage sensors, thereby being economically efficient and not consuming the calculation load during the measurement time even if the number of sub modules increases.


The binding of [3H]mianserin to homogenates of cockroach nerve cord was investigated, using a centrifugal binding assay. Nonspecific binding was defined as binding in the presence of 0.1 μM phentolamine. Specific binding was saturable and indicated a high affinity site (KD = 39.6 nM and Bmax = 0.8 fmol μGg−1) and a low affinity site (KD = 648.9 nM and Bmax = 5.9 fmol μg−1). The binding was reduced or abolished by heat, detergents, trypsin and HgCl2. Incorporation of CaCl2 or NaCl into the medium reduced binding in a dose-dependent fashion, whereas MgCl2 and NaF inhibited binding in a biphasic manner. The stable GTP analog, 5′-guanylylimidodiphosphate, reduced the high affinity binding at 10 μM. Phentolamine, D,L-octopamine, demethylchlordimeform (DCDM), clonidine, and D,L-synephrine are effective displacers of [3H]mianserin-binding, whereas dopamine, acetylcholine, serotonin (5-HT), and histamine show poor or no displacement. The pharmacological properties of octopamine-sensitive adenylate cyclase stimulation in cockroach nerve cord are similar to those of [3H]mianserin-binding.


Based on field relations and petrographic characteristics, alkali-feldspar granite in the Gigye area on the western side of the Yangsan fault is classified as an A-type granite. It is mainly composed of quartz, perthitic K-feldspar, and interstitial ferri-annite plus sodic amphiboles such as riebeckite and arfvedsonite, indicating crystallization under hypersolvus, anhydrous conditions. These petrographic features are the same as those of the A-type granite in the Gyeongju area on the east side of the Yangsan fault. These distinctive, pre-Eocene granites are separated by about 21.3 km, indicating Cenozoic dextral strike-slip of this amount along the Yangsan fault.

Armed conflict continued around the world in 2012. Many are captured on the 2013 Chart of Conflict included with this volume, and further details can be found in the IISS Armed Conflict Database. In a section new to The Military Balance this year, the IISS examines the wars in Afghanistan and Syria, analysing the course of both wars from November 2012 to November 2013. Both involve conflict between insurgents and governments, but with varying degrees of external assistance to all warring parties. A short concluding analytical essay compares the role of key military factors in both conflicts, offering some general conclusions about modern insurgency and counter-insurgency.


Older adults who transition to independent and assisted-living communities perceive their transition experience differently. This research focused on understanding what factors were predominant for a successful transition from a long-time home to a dependent living community. A constructivist grounded theory method was used to explore the experiences of 18 older adults who had relocated within the past year. The participants of this study were aged 65-95 years and are equally represented by gender. Equal numbers of respondents transitioned into independent and assisted-living accommodations. Five factors related to a central concept of behavioral attitude were found to be key for a successful transition. When an older adult reported a successful transition, their behavioral attitude was positive about their new living environment. The five factors that contributed to their positive attitude are creating a new place, increased community integration, sense of safety and security, independence while dependent, and accepting a new life stage. The theory that emerged from the research emphasizes that when an older adult has increased awareness about the five factors associated with adapting to a dependent living community, this awareness will promote a positive behavioral attitude and increase the opportunity for success during and after a transition. Family members, LTC community administrators and social workers could all benefit from understanding these factors for a successful transition. Enhancing a positive experience for an older adult and improving their behavioral attitude toward the new transition.

Nigeria The importance of seaweeds cuts across various environmental, ecologic, socio-economic benefits and services as food for man, in the phycocolloids and expanding phycosupplement industries, as sink for excess carbon dioxide and excess nutrients; for sustainable energy generation and as fossil fuel substitutes. In view of this, seaweeds could become an important economic niche for Asian(Japan and China), Nigeria and other coastal African countries provided adequate research is undertaken in studying their diversity, biochemical compositions and potentials for culture in order to harness the numerous opportunities which can be derived. This paper revels some products and uses of seaweeds to stimulate research and utilization of seaweed resources in the near future. in Nigeria and other interested countries. © 2013 PSCI Publisher All rights reserved.


We give necessary conditions for when a subset of $\mathbb{T}^n$ can contain the support of some non-zero RP-measure. Among other things we show that the support of a positive RP-measure cannot be contained in reflections of inverse images of half-planes by certain functions in $A(\mathbb{D}^n)$, sets of linear measure zero, and when $n=2$, graphs of strictly increasing functions. For $n=2$ we also prove that failure to contain the support of any positive RP-measure implies that restrictions of functions in a subspace of $A(\mathbb{D}^2)$ are uniformly dense among the continuous functions on a related set.


Objective To investigate the correlation and clinical significance of serum cystatin C (Cys-C) level and ischemic stroke.Methods A total of 147 patients with acute ischemic stroke were recruited. They were divided into small,medium and large sub-groups according to the infarct volume of the brain.They were also divided into high-risk group(the National Institute of Health Stroke Scale 8) and low-risk group(NIHSS≤8) according to the scores of NIHSS.Sixty patients without stroke were selected as a control group.A particle enhanced immunoturbidimetric assay was used to detect the serum Cystain C levels,investigate the relationship between Cystain C level and ischemic stroke and analyze the correlation between Cystain C level.Results①The serum Cystain C level 1.20±0.40rng/L in the ischemic stroke group was significantly higher than 0.86±0.23 mg/L in the control group.The difference was statistically significant(P 0.05).With the increase in infarct volume,the serum Cystain C level also increased.The difference was statistically significant(P0.05).②The serum Cystain C level 1.33±0.52 mg/L in a stroke recurrence group was higher than 1.12±0.28 mg/L in a initial stroke group.The difference was statistically significant(P 0.01).③The serum Cystain C level has no correlation with the NIHSS score, but the serum Cystain C level 1.37±0.68 mg/L in the high risk group was higher than 1.15±0.27 in the low risk group.The difference was statistically significant(P0.01 ).④The serum Cystain C level was positively correlated with homocysteine(Hcy)(r =0.189,P =0.022) and very low density lipoprotein cholesterol(VLADL-C)(r=0.255,P =0.002),however,it was negatively correlated with high density lipoprotein cholesterol(HDL-C)(r= -0.173,P = 0.036).⑤Multivariate logistic regression analysis showed that the serum Cystain C was a risk factor for ischemic stroke(OR = 2.646,95%CI 1.621- 4.317,P0.01 ).Conclusion The increased serum Cystain C level is an independent risk factor for ischemic stroke,it is associated with the lesion size and the severity of cerebral infarction.The serum level may be used as a reference indicator for the occurrence and development of cerebral infarction and disease surveillance.

This project, funded by the Nuffield Foundation, investigates how participation in out of school activities varies for children from different backgrounds and how this relates to outcomes at age 11. The study includes analysis of the Millennium Cohort Study as well as case studies in primary schools to explore the relationship between engagement in out of school activities and attainment. In this research brief, we highlight the importance of after school clubs for increasing disadvantaged children's access to activities and explore what it is about how these clubs are structured and delivered that helps to engage less affluent families.


There are several approaches to regional integration, both in actor's strategies and in academic analysis. One of the pioneering political science efforts at providing a causal model of regional integration was developed under the stimulus of events in Western Europe in the late 1950's and not surprisingly it reflects these origins. We will refer to it as academic neo-functionalism.

Water quality of Surma River is frequently deteriorating for the last few decades since ever-growing human activities, poor drainage facilities, and direct disposal of industrial and municipal waste. Along with poor structure, natural canals (local name Chara) are responsible for the conveyance of surface runoff from its urban catchments to the receiving Surma River. The purpose of this study is to assess the degree of pollution in context of CCME-WQI (Canadian Water Quality Guideline-Water Quality Index) in Surma River by determining various physico-chemical parameters. Data from sample analysis, the concentration of DO (Dissolved Oxygen), BOD (Biochemical Oxygen Demand), TSS (Total Suspended Solid), Turbidity and Fe (Iron) do not meet the satisfactory level. Particularly this study suggested that water quality of this river is affected for high turbidity and BOD due to soil erosion, runoff and municipal effluent discharge without any treatment. Beside these, concentration of heavy metals in Surma River is a bit high which poses another impact for the user of Sylhet city whom are mainly dependent on Surma River. Surma River is found to 15.78 according CCME-WQIs model which indicates that water quality of this river near Sylhet city is Poor and frequently impaired.

 Key words: Natural canals, Surma River, pollution, solid waste, disposal.


In this article, the author investigates the determinants of working capital requirements of 66 firms in Nigeria using panel data for the period 1997–2007. The results suggest that sales growth, firms' operating cycle, economic activity, size, and permanent working capital are firm specific characteristics that positively drive working capital policy. Leverage, however, is inversely related to working capital requirements. Essentially, the results imply that traditional valuation methods used to quantify the efficiency of corporate working capital policy may be suspect as increased investments in operating working capital may be necessitated by increased business uncertainties. In general, the findings suggest that some of the insights from modern finance theory are potable to Nigeria.
