Lithium‐sulfur batteries (LSBs) with outstanding theoretical capacity and environmentally friendly properties are regarded as next‐generation energy storage devices. However, the shuttle effect of lithium polysulfide (LPS) limits the practical application of LSBs. Herein, we introduce an aqua‐processable carbon quantum dot (CQD)–assisted resilient waterborne polyurethane (WPU) network binder for sulfur cathodes. WPU is a well‐dispersed colloidal system with abundant polar groups that is suitable for regulating LPS shuttle effects. CQDs were prepared from WPU by hydrothermal treatment. The CQDs enabled facile electron/ion transport, enhanced the adsorption capability of LPS, and formed a robust network. Moreover, the chemical similarity between WPU and CQDs enabled the formation of a well‐dispersed system, thereby affording optimal electrochemical performance. The WPU‐CQD binder systems exhibited stable cycling performance at a high rate of 2C, with only 0.028% retention decay per cycle over 1000 cycles.


This study employs fluorescence spectroscopy to characterize the binding properties of a newly synthesized cardiac agent, V-09, on bovine serum albumin (BSA). This compound shows the highest cardiac activity in the whole series. The binding constants K at 25°C and 37°C are obtained, the values are 7.12×104 l mol–1, 4.66×104 l mol–1, respectively. The standard enthalpy change (ΔH0) and the standard entropy change (ΔS0) are calculated to be –27.13 KJ mol–1 and 1.854 J mol–1 K–1, which indicated that hydrophobic forces play major role in the interaction between V-09 and BSA. The binding average distance between V-09 and BSA (2.57 nm) is obtained on the basis of the theory of Főrster energy transfer.


This study aimed to discuss and analyze problems regarding the storage of minutes of notary deeds made electronically. This study used a normative research method. The approach used a statutory approach and a conceptual approach. The minutes of the notarial deeds can be made electronically because they were permitted by several regulations. Electronic deed minutes can be stored as long as the original deed was still made and stored conventionally. The validity of the position of the minutes of the determined that was stored electronically as evidence was determined by the judge's consideration.


We investigate the possibility of making all functions in Baire class , < ! 1, close to continuous by adding to them a single function of Baire class + 1. Remnants of continuity are preserved, in various senses, in arbitrary Borel functions. Yet another way in which this is true has been considered recently by several authors. Given < ! 1, can we nd a single function f which makes all functions of the form f +g, with g Baire class , look continuous? Obviously, we would like f to be as simple as possible and the functions f +g as close to continuous as possible. The following four denitions are normally used, in this context, to measure the \degree of continuity" of f +g. How to measure simplicity of f will be clear from the statements of results. Let g be a function mapping a separable metric space X into the reals. g is Darboux if images of connected sets are connected. g is connectivity if the graph of the restriction of g to any connected subset of X is a connected subset of X R. g is almost continuous if any open subset of X R containing the graph of g contains also the graph of a continuous function from X to R. g is extendable connectivity if g(x) = G(x; 0), for all x 2 X, for some connectivity function G : X [0; 1]! R. It is known that if X = R, then the above classes are getting properly smaller as we go down the list and that all of them contain the continuous functions.

Introduction: Scleroderma remains one of the most severe rheumatic diseases and is characterized by a progressive course, disability, and a high level of mortality. According to world statistics, the average disease incidence rate ranges from 0.6 to 19 per 1 million, spreading out – from 4 to 242 per 1 million. An early start of physical therapy with the inclusion of new techniques in conjunction with medical treatment remains topical.
Aim: To develop and experimentally test the effectiveness of a complex physical therapy program for people with a limited form of scleroderma.
Clinical case: The study involved a woman with a limited form of scleroderma. At the beginning and the end of the study, laboratory studies were conducted: the level of hemoglobin, ESR, ionized calcium, Scl-70 (ANA-Screen); clinical signs were investigated: swelling of the hands, Raynaud's phenomenon, fibrous myopathy, skin tightening assessment (according to G. Rodnan), goniometric studies and manual muscle testing. Physical therapy consisted of: daily kinesiotherapy in the form of active-passive exercises with an emphasis on fine motor skills of fingers and active exercises for the temporomandibular joint, coniferous salt bath for wrists, therapeutic massage and Kinesio taping of wrists.
As a result of the study, the mobility of the joints of the upper limbs increased by an average of 5-35 °; the muscle strength increased from 3 to 5 points and the quality of life of the patient improved.
Conclusions: Physical therapy made it possible to improve the mobility of the wrist and metacarpophalangeal joints, increase muscle strength, and reduce the main manifestations of the disease. The continuation of physical therapy complex will improve the quality of life of these patients and the further prognosis of treatment.


Methods for detecting a short tandem repeat polymorphism (STRP), such as fragile X syndrome, wherein PCR is used to amplify nucleic acid along the chromosome in the genomic DNA which includes all of the STRs of interest plus a substantial contiguous segment of the nucleic acid adjacent to the STRs. Single-stranded product is then obtained, and colorimetric-labeled oligonucleotides which target for (i) STRs and (ii) the contiguous DNA segment are hybridized with this single-stranded product which is then bound to a solid phase and separated from the remainder of the target material. The labeled oligonucleotide target material is recovered by treatment with base and then hybridized to a microarray having a plurality of spots containing suitable oligonucleotide probes complementary thereto. Following hybridization, colorimetric intensities of the hybridized labeled target material present at specific spots on the microarray are measured to obtain individual values which are compared with results from known control samples to accurately quantify the number of STRs in the region of interest of the DNA being analyzed. ® KIPO & WIPO 2007


Existing cylindrical deployable structures have poor controllability of deployment or weak bearing capacity. In order to satisfy the application needs of cylindrical deployable structures in the space industry, a cylindrical net-shell deployable mechanism is established in this article. The proposed cylindrical net-shell deployable mechanism has a regular cuboid shape in the folded state and a truss structure in the deployed state, and it can fit cylindrical surface, parabolic cylindrical surface, sine cylindrical surface and so on. Furthermore, based on reciprocal screw theory and screw synthesis theory, the mobility of cylindrical net-shell deployable mechanism in the whole motion cycle is analysed by the proposed equivalent model method. Results show that the cylindrical net-shell deployable mechanism is a single-degree-of-freedom mechanism. Moreover, a prototype is manufactured, and its motion performance is tested. The experiment shows that the cylindrical net-shell deployable mechanism has a smooth motion performance, and the mobility analysis method for complex coupled mechanism in this study is valid. This study has a certain significance in expanding the application field of cylindrical shell structure.


Recent advances in the investigation of the relationship between language and cognition have demonstrated that speakers of English categorise objects based on their common shape, while speakers of Yucatec and Japanese categorise objects based on their common material (Lucy & Gaskins 2003; Imai & Mazuka 2003). The current study extends that investigation to the domain of bilingualism. Results from a cognitive categorisation task show that intermediate Japanese L2 English speakers behaved similarly to Japanese monolinguals, while advanced Japanese L2 English speakers behaved similarly to English monolinguals. The implications of these findings for bilingualism and second language acquisition are discussed.

Abstract

Hallway medicine has taken a forefront in Ontario Healthcare and is influencing patient care. The Conservative party is focused on increasing fiscal responsibility.  Joseph Brant Hospital's General Internal Medicine Rapid Assessment Clinic (GIMRAC) was initiated in 2016 in an effort to decrease hallway medicine and assume that fiscal responsibility by having the right patient in the right place at the right time. Appropriate patients are referred from the Emergency department and Inpatient units and provided with a timely assessment by an internal medicine physician in a clinic setting close to home. The GIMRAC has prevented over 3500 hospital admissions and allowed for over 800 early discharges since its inception. Volumes have increased by greater than 350% to date.

Specialty medical care, collaboration between departments, and an intense focus on client centered care, have supported these numbers. The governance of an Ambulatory Care Steering Committee and consistent monitoring of metrics amongst staff, leadership, and finance, has provided the transparency and accountability needed to further grow. A review of community needs allows for proper alignment of care within the clinics. A realignment of resources and co-location of clinics, allows for visibility, cross training of staff, and collaboration of expert care.

The aim of this presentation is to inform conference attendees about the type of patient optimal for this model of care, challenges surrounding referrals, follow up, limited resource utilization, and barriers to further growth. Strategies related to the daily dynamics

between frontline providers (ie., physicians, nurses, and hospital administration) will be outlined.

We propose and demonstrate a compact, cost-effective, multiwavelength laser source employing self-injection locking scheme on InAs/InP quantum-dash (Qdash) laser diode. The device is shown to exhibit Fabry–Perot modes or subcarriers selectivity of 1 to 16 between ∼1600–1610 nm, with corresponding mode power (side mode suppression ratio) variation of ∼10 (∼38) to ∼−2.5 (∼22) dBm (dB), and able to extend beyond 1610 nm, thereby encompassing >30 optical carriers. Then, we utilized a single self-locked optical carrier at 1609.6 nm to successfully transmit 128 Gb/s dual-polarization quadrature phase shift keying signal over 20 km single mode fiber with ∼−16 dBm receiver sensitivity. To stem the viability of unifying the transceivers and addressing the requirements of next generation access networks, we propose self-seeded Qdash laser based wavelength division multiplexed passive optical network, capable of reaching a data capacity of 2.0 Tb/s (<inline-formula><tex-math notation="LaTeX">${\rm{16\,\times \,128\, Gb/ s}}$</tex-math> </inline-formula>) in L-band.


The invention relates to a method for producing mineral fibres comprising inserting raw materials (4) into a rotary furnace (1) with electrodes (9), then melting the raw materials (4) in said furnace (1) to form a molten vitrifiable material (8), then pouring the molten vitrifiable material (8) in the furnace via a side outlet of the furnace to supply a distribution channel (11), then pouring the molten vitrifiable material (8) via a hole (12) in the bottom of the distribution channel to supply a drawing device, then transforming the molten vitrifiable material (8) into fibres by means of said drawing device, the flow of molten vitrifiable material (8) between the furnace (1) and the distribution channel (11) passing below a height-adjustable metal barrier (10) comprising a casing cooled by a flow of coolant fluid. Adjusting the height of the barrier (10) affects the temperature of the glass to be drawn into fibres in order to bring it into the viscosity range required for drawing.

This thesis seeks to chart the creation, development and eventual demise of the child analytic training of The Society of Analytical Psychology (SAP),the foremost Jungian Society in the UK. The brainchild of the Society's founding director, Michael Fordham, the creation of the child training drew on the talents and persistence of many committed individuals. Through oral history interviews and archival research I weave together a narrative that will serve as testament to this achievement and offer first hand recollections for posterity. Through these sources the narrative also explores the difficulties that the training faced and which ultimately led to its eventual demise. Additionally I interrogate the current status of this tradition of child analysis and ask the question whether or not the tradition continues to exist and if so in what ways; I conclude that currently the tradition can only be said to exist in an attenuated form and that the future is bleak. In the course of the thesis I locate the SAP training within the development more generally of child analytic provision within the UK, the relationship of that to the child guidance movement and to the psychoanalytic diaspora, which made it possible. I describe the current obstacles faced by the child psychotherapy discipline as well as psychoanalytic psychotherapy in the NHS.

At present, there exist rich amount of experimental data for the weak decays of heavy flavor hadrons. Weak leptonic and semileptonic decays are reasonably well understood in the Standard Model of fundamental interactions, however, weak hadronic decays have posed serious problems for the model as these decays experience strong interaction interference due to the gluons exchange among the quarks involved. In this thesis, two-body weak hadronic decays of heavy flavor mesons have investigated in the framework of the Standard Model. It has been found experimentally that two-body decays dominate the decay spectrum. Theoretical focus has, so far, been on the s-wave meson (i.e. pseudoscalar (P) and vector mesons (V)) emitting weak decays. However, charm and bottom mesons, being heavy, can also emit p-wave mesons, i.e. axial-vector (A), tensor (T) and scalar (S) mesons. Naively, the p-wave mesons emitting decays of the hadrons are expected to be suppressed kinematically due to the large mass of these meson resonances. However, now reasonable amount of experimental data has become available for branching ratios of the p-wave emitting decays of heavy flavour mesons which are found to be quite large, and require theoretical understanding. In this thesis, such weak decays of bottom mesons ( − B , 0 B and s B ), which are the bound state of bottom quark and a light antiquark, and


The hydrogen pressure dependence of the ring-opening reactions of propylcyclobutane was studied at three different temperatures over Pt/SiO[sub 2] catalyst. At 373 and 573 K, only hydrogenative ring opening occurs, while appreciable amounts of aromatics, ring enlargement, and cracking products are formed at 673 K. At 373 K, the ring opens selectively in the sterically more hindered direction over both the clean and the working catalyst, yielding heptane as the major product. The selectivity is lost at 573 K and 673 K: 2,3 C-C bond scission, i.e., formation of 3-methylhexane occurs with initial rates comparable to that of 1,2 C-C bond scission. Over the working catalyst, the selectivity is close to statistical, with a slight excess of 3-methylhexane. An increase of hydrogen pressure has different effects on the ring-opening reactions, depending on the reaction temperature. The initial rate of product formation vs hydrogen pressure curves exhibit three extremes at 373 K, but they increase monotonously at 573 and 683 K. Over the working catalyst, the hydrogen pressure dependence curves display three extremes at 373 K, pass through a maximum at 573 K, and increase monotonously at 673 K. Mechanisms over both the initial and working catalysts are discussed on themore » basis of regioselectivity data and hydrogen pressure dependence curves. 24 refs., 3 figs., 1 tab.« less


This roundtable brings together a group of academics and artists working throughout Europe to discuss the question of memory in theoretical and artistic contexts at a historical moment highly preoccupied with acts of commemoration and moving memory. As the convenors of this roundtable, we are working and writing within an Irish context. Hence, we ourselves are in the middle of the Irish State's 'Decade of Centenaries', which marks events from 1912–1922 and the founding of the Irish Free State. At the time of coordinating this roundtable, we have been engaged in the yearlong celebration of the Easter Rising centenary in particular, celebrations that have raised anew debates about scales of commemorative practice in relationship to the representation of militarisation as a primary commemorative mode at state level and the need to animate and centralise marginalised voices, particularly those of women and children. The artists participating in this roundtable from both the Republic and Northern Ireland have engaged centrally with questions of national narratives, minority histories, and scales of remembrance as communal (or performative) acts; the academic participants are, likewise, informed by their work in diverse areas of memory studies, and particularly by their membership of the COST Action Network In Search of Transcultural Memory in Europe (2012–16).


trabo's geography, as anyone who has perused it will know, is suffused with a profound, nearly obsessive, interest in Homer.1 The desire to demonstrate Homer's knowledge of geographical information at every turn (even where it seems prima facie unlikely) is matched only by the determination with which Strabo "solves" notorious problems of Homeric geography such as the location of Nestor's Pylos or the identity of the "Ethiopians divided in twain" visited by Poseidon.2 Strabo's concentration on such arcana, often to the exclusion of more properly "geographical" material, has understandably exasperated many modern readers with different ideas about what constitutes geography. On the other hand, the overwhelming geographical focus of his Homeric criticism has rendered his extensive comments of only passing interest to scholars of ancient poetic criticism; at best they provide evidence for the methodological principles of a writer "conditioned by the dominant position of Homer's poetry in Greek life to regard Homer as knowledgeable and trustworthy in matters of geography also."3 Recently, however, a more sophisticated understanding of the historical (or temporal) dimensions of Strabo's geographical project has better integrated his Homeric fixation into the work as a whole.4 We see now that his reverence for Homer is linked to the importance of historical memory (palaia; mnhvmh: 1.1.16) within his notion of geography.5 If, as Katherine Clarke writes, "the stories told about the past were precisely what gave a place its present identity [to Strabo]," the stories told by Homer would naturally be


Literature is the learning about human being,so literature should show morality. Moreover, character's moral tendency is related to the author.

The proximity of businesses targeting the same market segment, meeting the same needs and operating in a similar way is generally believed to indicate more competition. However, this situation can be beneficial for the companies involved, and it may not necessarily generate an adverse environment. This study sought to analyse a group of restaurants that operate under similar conditions and that are located within the same area in order to identify the potential benefits and drawbacks of choosing this strategy to deal with market pressures. The research was based on a sample of 1,358 customers from 52 small restaurants. Diverse information-gathering techniques were combined such as observations, interviews and surveys. The data gathered was used to characterise different groups of variables' behaviour based on descriptive statistics. In addition, bivariate statistics were utilised to test the hypotheses, while multivariate statistics were used to conduct correspondence analysis. The results reveal that, in the cases analysed, the parties involved benefit from the existing condition when a process of distribution of demand is present and advertising expenses are minimised.


DD is however the preferred method of exploration drilling for graphite, as the graphite flakes and host rock are relatively undisturbed when retrieved as core ( Figure 4 ). Many exploration companies employ both RC and DD methods to optimise drilling density.

Carbon may be present in rocks in several different forms, including organic carbon, carbonates or graphitic carbon. Depending on the method used, carbon in rocks may be reported as total carbon (organic carbon + carbon in carbonate minerals + carbon as graphite) or as total graphitic carbon (TGC) (total carbon - (organic + carbonate carbon)).

Assaying for graphitic carbon quantifies the amount of graphite contained within a deposit, but does not indicate the amount of graphite that may be recoverable; the purity of such graphite; the particle size distribution of recovered (liberated) graphite; the process required to liberate and produce a graphite concentrate; or likely markets for that product.

Tallgrass prairies are an important source of hay and summer forage in the Great Plains. A study was conducted in 1989 and 1990 on two excellent condition tallgrass prairies in eastern Nebraska to determine if the production and forage quality of big bluestem (Andropogon gerardii var gerardii Vitman), the dominant warm-season grass, could be manipulated by burning on different dates in the spring and applying fertilizer. Vegetation was harvested at approximately 30-d intervals from mid-June to mid-August. Big bluestem was separated from the vegetation, weighed, analyzed for in vitro dry matter disappearance (IVDMD), crude protein concentration (CP), and neutral detergent fiber concentration (NDF) [...]

This paper studies the performance predictability of external fund rating systems. Most investors use 5 stars rated funds to build their portfolios. The underlying idea is that funds which were the best during the last three years will be better performers than the other funds in the future. It implies that the 5 stars rating is a good persistence measure of the performance. Using a Markov modelling and the seminal empirical work of Garnier and Pujol (2007), we show that ratings persistence is poor. It means that fund selection or a fund picking process may not be reduced to choose funds in a 5 stars rated universe.

The natural hydrology of streams and rivers has been extensively altered by dam construction, water diversion, and climate change. An increased frequency of low-flow events will affect fish by changing habitat availability, resource availability, and reproductive cues. I reviewed the literature to characterize the approaches taken to assess low-flow events and fish, the main effects of low-flow events on fish, and the associated mechanistic drivers. Most studies are focused on temperate streams and are comparative in nature. Decreased stream flow is associated with decreased survival, growth, and abundance of fish populations and shifts in community composition, but effects are variable. This variability in effects is probably caused by context dependence. I propose 3 main sources of context dependence that drive the variation in fish responses to low-flow events: attributes of the low-flow event, attributes of the habitat, and attributes of the fish. Awareness of these sources of context dependence can help managers interpret and explain data, predict vulnerability of fish communities, and prioritize appropriate management actions.


*† ‡ A computational study of an unforced and periodically forced two-dimensional shear layer behind a backward facing step is presented. The goal is to investigate the optical aberrations caused by large and small scale structures in the flow field. Fluid dynamical as well as optical data was used to correlate the flow structures with the optical distortions. Simulations using the compressible Navier-Stokes equations were used to directly compute the unsteady density field. This density data, as well as the computed Optical Path Difference, is analyzed using Proper Orthogonal Decomposition to determine the optically detrimental structures which are the eventual target of feedback flow control. The investigations showed that POD of the density is a well suited tool for this analysis since its changes are largest in the optically detrimental coherent structures in the shear layer.


In order to understand how bunchgrasses achieve dominance over other plant growth forms and how they achieve dominance over one another in different environments, it is first necessary to develop a detailed understanding of how their growth strategy interacts with the resource limits of their environment. Two properties which have been studied separately in limited detail are architecture and disproportionate resource allocation. Architecture is the structural layout of organs and objects at different hierarchical levels. Disproportionate resource allocation is the manner in which resources are allocated across objects at each level of hierarchy. Clonal architecture and disproportionate resource allocation may interact significantly to determine the growth ability of clonal plants. These interactions have not been researched in bunchgrasses. This thesis employs a novel simulation technique, functional-structural plant modelling, to investigate how bunchgrasses interact with the resource constraints imposed in humid grasslands. An appropriate functional-structural plant model, the TILLERTREE model, is developed that integrates the architectural growth of bunchgrasses with environmental resource capture and disproportionate resource allocation. Simulations are conducted using a chosen model species Themeda triandra, and the environment is parameterised using characteristics of the Southern Tall Grassveld, a humid grassland type found in South Africa. Behaviour is considered at two levels, namely growth of single ramets and growth of multiple ramets on single bunchgrass clones. In environments with distinct growing and non-growing seasons, bunchgrasses are subjected to severe light depletion during regrowth at the start of each growing season because of the accumulation of dead material in canopy caused by the upright, denselypacked manner in which they grow. Simulations conducted here indicate that bunchgrass tillers overcome this resource bottleneck through structural adaptations (etiolation, nonlinear blade mass accretion, residual live photosynthetic surface) and disproportionate resource allocation between roots and shoots of individual ramets that together increase the temporal resource efficiency of ramets by directing more resources to shoot growth and promoting extension of new leaves through the overlying dead canopy. The architectural arrangement of bunchgrasses as collections of tillers and ramets directly leads to consideration of a critical property of clonal bunchgrasses: tiller

In this study, we have used Lie group analysis procedure to propose a novel model for transforming the governing equations of double diffusive MHD hyperbolic tangent fluid flow model into a system of nonlinear ordinary differential equations (ODEs). The solution of these equations is then investigated numerically by employing Shooting method. We also reported and presented our results graphically illustrating the results and analysis of physical parameters on concentration, velocity, and temperature profiles and on other physical quantities present in the flow model. The results show that fluid temperature increases with rise in the modified Dufour and velocity slip parameters whereas opposite behavior is observed for thermal slip parameter. Moreover, the Nusselt number declines with enhanced values of modified Dufour parameter whereas its opposite effect has been observed for Dufour-solutal Lewis number and Prandtl number.

This Appendix summarises what is perhaps the most widely-used systems engineering Standard in the world: ISO/IEC 15288:2008 Systems and software engineering - System Life Cycle Processes. The Appendix presents information on ISO15288:2008 using the 'seven views' approach to Process modelling that is discussed in Chapter 3.1. Five out of the seven possible Views are presented; no Information Views or Process Behaviour Views are given as the Standard is written at a level which does not allow these Views to be abstracted and modelled. The Views are given without commentary and are intended to be used as a reference in conjunction with a reading of the Standard. As an aid to understanding the content of ISO15288:2008, the reader is also directed to the INCOSE Systems Engineering Handbook.

Solid waste management is a challenge for large urban areas around the world. Removing garbage from residential, institutional and commercial locations in cities is a major logistical and operational task. Waste management is usually a function of local government, and is often a city's largest budget item. Solid waste generation rates are rising fast, particularly in cities experiencing increasing population rates and higher economic activity, putting pressure on municipal governments to deal with rising costs and environmental impacts.

Fibromyalgia (FM), which primarily affects women, is one of several medically unexplained illnesses. In many instances, FM is accompanied by one or more of these illnesses, which often confounds the approach to diagnosis and treatment. Although the pain and tenderness of FM are very real, many patients seen in the primary care setting are not taken seriously and do not receive appropriate treatment. However, the equation has changed with the recent approval of 3 drugs for FM. This article describes FM, reviews the evidence supporting FM as a chronic central pain state (as opposed to a rheumatologic disorder), and explains how FM relates to other medically unexplained illnesses. The article also presents an algorithm for the treatment of FM in clinical practice. (Adv Stud Pharm. 2009;6(5):134-139)

XML's rapid adoption as the data representation standard in web based systems is increasing the interest in applying XML query languages (as XPath) to access XML repositories. This technology entails new challenges related to testing, mainly derived from the hierarchical data representation in XML documents and the expressiveness of the query language. In this paper, we present a technique for the automatic generation of test cases for XPath expressions using the SPIN model checker. Both the XML schema and XPath query are previously modeled in the SPIN language and the test cases are obtained from the counterexamples that it generates.

ABSTRACT In December 2019, the novel coronavirus 2019-nCoV, which has caused the latest public health emergency of international concern, began to spread with exponential speed around the whole world. To further the understanding of how media technologies contribute to knowledge management for a pandemic outbreak communication (POC), this paper, through Key-route main path analysis (MPA), investigates the research literature on POC. This paper found that studies on the main paths mainly focus on public cognition at the beginning and later the attention is transferred to how to fight against the outbreak and thus reveals the changing role of media technologies in knowledge management. To examine the dynamic structure of communication between government and public, this study relies on the "enactment" perspective to shed light on how the government makes sense of the media technologies and the circumstances of the pandemic to further knowledge management in POC.


Background: Emergency reports show that acute intoxication involves 7-10 % of all patients applying the emergency department and a group of these patients were followed in intensive care units. The aim of this study is to examine 264 patients who were diagnosed and followed as intoxications between 2010-2011 years in our intensive care unit. Methods: In this study 264 patients who were diagnosed and followed as drug intoxication between 2010-2011 years in Şanlıurfa Balıklıgöl Hospital intensive care unit were investigated. Results: One hundred and ninety-two of patients were female (72,7%), and seventy-two were male (27,3%); female : male ratio was 2,6:1. The most common intoxication reason was drugs. Frequently used drugs were antidepressants (88 patient, 36,36%). Eight of them were intubated for respiratory depression. Two hundred sixty of them were discharged from hospital (98,4%), 1 of them were transported to another unit (0,37%) and 3 of them were died (1,13%). Conclusions: As a result, we decided that antidepressant drug use is the most frequent reason of intoxication in intensive care units.


Every time Mycobacterium tuberculosis is recovered from human specimens by microbiological culture, the diagnosis of active tuberculosis (TB) is definite 1. As culture growth of M. tuberculosis may take ≥2 weeks on average, clinicians need to rely on other methods to achieve rapid diagnosis of active TB and justify the decision to treat the patient. The decision to initiate anti-TB treatment can be difficult, especially in children, and is currently based on different criteria including: 1) medical history and local epidemiology; 2) chest radiography; 3) the microscopic detection of acid fast bacilli (AFB); 4) amplification of M. tuberculosis nucleic acids from biological specimens; 5) the detection of mycobacteria-specific immune responses in the tuberculin skin test (TST); and 6) interferon (IFN)-γ release assays (IGRAs). Furthermore, several scoring methods have been proposed to diagnose TB in children when microbiological evidence is lacking. While serological antibody-based tests have not been successful 2, novel methods for the diagnosis of TB are constantly being developed 3.

IGRAs, commercially available as the QuantiFERON-TB-Gold® In Tube (QFT-GIT) test (Cellestis, Carnegie, Australia) and as the T-SPOT.TB® test (Oxford Immunotec, Abingdon, UK), are now established in many countries as advanced tools for the immunodiagnosis of latent TB infection (LTBI). In contrast to the mixture of antigens in the purified protein derivate, which is used in the in vivo TST, the IGRA detects effector memory responses to a limited number of specific RD1 peptides by peripheral blood mononuclear cells (PBMC) ex vivo . The genes that encode for the RD1 proteins are absent in the bacille Calmette-Guerin (BCG) vaccine strain. Consequently, in BCG-vaccinated recent contacts of infectious cases, IGRA responses correlate better to M. tuberculosis exposure than the TST 4–8. Therefore, it is plausible that IGRAs are superior to the TST in predicting the development …


What began as a search for the next Greenbushes has delivered Venture Minerals Ltd a promising VMS discovery about 240 km south of Perth.


Scanning microscopic observations were made of the surface structures of isolated scales of Tilapia mossambica (Peters). The circuli were found to form numerous minute processes called scalar denticles, which may act to secure the position of the scale with reference to surrounding dermal tissues. The skin covering the lunula of the scale includes a number of pores which are thought to represent the terminal openings of dermal mucous cells. This part of the skin also shows peculiar epidermal surface patterns. These surface patterns may be indicative of areas subject to increased mechanical stress.


The fate of newspapers and the music industry is a harbinger of what awaits every company: an aging business model in its death throes as people finally wake up to the grim fact that their products and the way they deliver them are completely out of sync not only with what customers want but how they want it. But Michael Malone–the author who, when the Internet was still the domain of technical experts, enabled his readers to see clearly the opportunities of the then-emerging digital age–is back and once again making sense of a future just around the corner.


Seven hematopoietic cell lines, four derived from the peripheral blood of patients with Down's syndrome (DS) and three from normal persons, were irradiated with 100, 150, 300, and 500 rads from a /sup 60/Co source and harvested for cell count and chromosome aberration studies every 12 hours for 72 hours post irradiation. Cell growth inhibition and an increase in chromosome aberration were observed in all the cell lines at each dose level and time interval. No significant difference was observed in the effects between DS and normal cell lines. The most common types of aberrations in the 12-hour samples were chromosome and/or chromatid breaks. In the later samples, chromatid exchanges were predominant. The results of the variance analyses on the induced chromosome aberrations in six lines (three DS and three normal lines) showed radiation dosage to be the largest component of total variance, following postirradiation duration and cell lines. The samples harvested 24 and 36 hours post irradiation generally showed greater effects than the samples of other harvest durations. The cell line variance could only be attributed to the differences among and between individual cell lines rather than the difference between DS and normal cell lines.


The method of Wigner and Seitz for calculating the cohesive energy of metallic sodium is compared with a recent method of L?wdin, and reasons are given for preferring the former. A simple calculation shows that L?wdin's use of the LCAO method in constructing his one-electron functions must give rise to an error in the energy greater than the correlation energy as estimated by Wigner, so that L?wdin's results should not be used in assessing the accuracy of Wigner's formula.


The article examines the evolution of the main features of the Russian economy in terms of the types of key actors of economic development. The concept of the general actor as the predominant type of relatively independent socio-economic subsystems that determine the impact on the functioning of the national economy is introduced. The movement of the economy from "the state economy" to "the economy of individuals" and further to "the economy of socio-economic and administrative-political systems" is traced. The preconditions for the transition of the national economy to the phase of the systemic economy as the harmonic economy with high-level coordination of various-scale and various-quality subsystems of the economy and society are noted.

Emergency Operating Procedures (EOPs) generally and an accident managment (AM) particulary play a significant part in the safety philosophy of NPPs since many years. A better methodology for development and validation of EOPs is desired. A prototype of an Emergency Operating Procedures Analysis System (EOPAS), which has been developed at GRS, is presented in the paper. The hardware configuration and software organisation of the system is briefly reviewed. The main components of the system such as the knowledge base of an expert system and the engineering simulator are described. INTRODUCTION Since many years Emergency Operating Procedures (EOPs) play a significant part in the safety philosophy of NPPs as a further strengthening of the defence in depth principles. Existing conventional event-oriented procedures have been optimized and complemented by symptomoriented procedures, particularly for beyond design bases conditions. An important step in the development and implementation of EOPs is their validation. For this purpose, different methods based on reviews, walk-throughs or simulations may be used. Concerning simulation methods in real-time, plant specific training simulators are largely used for validation due to their large field of application and effectivity. In practice, for many NPPs, such simulators do not exist or are inaccessible, and/or the existing simulators do not cover the full spectrum of accidents for which the EOPs have to be validated. This makes the application of this method impossible in many cases. This paper describes a segment of an investigation that was conducted by the Gesellschaft fur Anlagen und Reaktorsicherheit (GRS) in the area of EOPs for beyond design base accident to assess and demonstrate the feasibility of using an expert system as an aid for the analysis of EOPs,in NPPs. The objective of the effort was to create and evaluate the EOPs knowledge base within the expert system, and to validate some characteristics of EOPs for suitable accident scenarios, simulated with a nuclear plant analyser. A prototype of an Emergency Operating Procedures Analysis System (EOPAS) [Ber96, Jak95] was developed, based on an expert system, and on the nuclear plant analyser ATLAS (ATHLET Analysis Simulator) [Vog93]ofGRS. The research presented in this paper has been funded by the the German Federal Ministry of Environment, Nature Conservation and Reactor Safety and the Federal Minister for Education, Research and Technology.


The objective of this study was to prepare and evaluate toxoid vaccines against enterotoxaemia in goats. Pure culture of Clostridium perfringens type D was used, already isolated and characterized by Institute of Microbiology, University of Agriculture Faisalabad, Pakistan. Epsilon toxin was extracted; the extracted toxin was subjected to LD50 determination and then with the help of formalin inactivation was done. The resulting toxoids were adjuvanted with two adjuvants including Montanide ISA 206 and Aluminium hydroxide gel (Alum). The pathogenicity and immunogenicity of prepared toxoid vaccines and commercial vaccine procured from VRI, Lahore, Pakistan were studied and compared initially in an experimental trial on rabbits and then in field trials on goat. Field trial was conducted on 72 goats divided into four equal groups (n=18). The Indirect Haemagglutination Test (IHA) was used to evaluate the antibody titer and challenge protection test was performed in rabbits. The results showed that antibody titers were significantly higher (P< 0.05) for in group vaccinated with Montanide ISA-206 adjuvanted toxoid vaccine. The geometric mean titer of Montanide group was 203.19, 456 and 670 at 14, 21 and 28 days post vaccination as compared to 181.02, 298.63 and 456.14 of Alum group on same days. Montanide vaccinated group also exhibited highest protection percentage (100%) post challenge as compared to 85.71%, 71.42% and 14.29% of group B, C and D, respectively.


ABSTRACT Thoughtful use of the narrative anecdote can be an important tool for pedagogical research, theorizing and the curriculum of teacher education. The epistemolog‐ical objective of the narrative is meaning; the narrative anecdote condenses meaning, simultaneously incorporating particularity and universality as well as the theoretical and the practical. Each retelling of a narrative anecdote provokes further reflection and raises questions, becoming part of the research process and a form of pedagogical theorizing. Through an illustrative telling of anecdotes, it is suggested that the discerning use of the narrative is one way in which we can construct and assimilate our knowledge base in teacher education. [1] [1] Based on a paper presented at 'The Narrative and Education' International Society for Educational Biography Faculty of Education, University of Toronto, Toronto, Canada, 26 April 1991.


The awakening of sexual maturity is an event of considerable physiological interest, and in the light of modern knowledge of the endocrine mechanisms a profound series of hormonal reactions is known to occur. Clinical observations have gradually brought to light some of the integrating factors involved in this epochal development; and by the careful study of aberrations from the normal, principally in cases of delayed or in accelerated puberty, it is now possible to state with some accuracy a single cause or a group of causes. It is now generally recognized that the pituitary is normally the primary directing power behind sex development, although there are most important second stations within the adrenal cortex and gonadal interstitial cells. The failure of sexual development is usually a selective or composite pituitary anterior lobe deficiency, and recent observation in pituitary cachexia has indicated the case whereby the whole endocrine basis may fail and sexual repression occur when the anterior pituitary is atrophic. Clinicians have recognized remarkable aberrations of physical and sexual development accompanying certain types of disease within the nervous system, and in this respect the region of the midbrain and especially the immediate neighbourhood of the floor of the third ventricle is principally concerned. It would appear from a study of case records that the hypothalamic area bears some close integration in function with the pituitary gland in regard to both lobes.


Decomposition of phenylpropioloyl peroxide and t-butyl phenylperoxypropiolate in cumene, toluene, and cyclohexane was investigated. Product analysis and kinetic study together with the findings that radicals separately generated caused the decomposition of these peroxides demonstrate of a new type of induced decomposition involving radical attack on the triple bond of these peroxides and subsequent β-scission.


In this paper, a technique for weighted pseudo-random built-in self-test (BIST) of VLSI circuits is proposed, which uses special scan cells and a new weight selection algorithm to achieve low power dissipation. It is based on weighted pseudo-random scan testing in which only 3 weight values are used - 2 fixed values (0 or 1) and 1 random value (0.5). A new weight selection algorithm is used to select a set of weights that achieves high fault coverage while reducing power. The idea is to minimize power by careful selection of the set of scan cells having fixed values (0 or 1) in order to reduce switching activity. To implement this in hardware, a new scan cell design is proposed that can do scan and capture in the normal mode as well as fixed-bit mode. The new scan cell hardware increases the area of a typical circuit by less than 4%, but reduces power by as much as 96%, as indicated in experiments performed on benchmark circuits.


Under Zinc (Zn) stress conditions, the production of vinblastine was increased in the medicinal plant Catharanthus roseus leaves. The combinational treatment with Zn and ethephon further promoted vin- blastine accumulation in C. roseus leaves compared with Zn-stressed plants. This elevation of vinblastine in- duced by ethephon was dependent on the dose of exogenous ethephon. Besides, the dry biomass accumula- tion of leaves and ethylene release were also increased significantly in Catharanthus roseus seedlings af- fected by the combined treatment with exogenous Zn and ethephon.

In an effort to understand the defect structure of the ternary II-VI compound zinc sulpho-selenide, the binary compound zinc selenide was investigated. Thin single crystalline films of zinc selenide were heteroepitaxially grown on (100) GaAs. Epitaxial layers from 5 to 50 microns thick could be readily grown using a chemical vapor transport technique. The layers had an excellent morphology with few stacking faults and hillocks. Detailed epitaxial growth kinetics were examined as a function of temperature and reactant concentration. It was found that hydrogen flow rate, source and substrate temperature affect the growth rate of the epitaxial films. Au - ZnSe Schottky barrier diodes and ZnSe - GaAs n-p heterojunctions were prepared from the epitaxial layers. Current-voltage characteristics were measured on both types of diodes. From capacitance-voltage measurements the residual doping density of the epitaxial layers were found to be of the order of 10/sup 14/ - 10/sup 15/ cm/sup -3/. Finally, we have begun to measure the deep level spectrum of both the Schottky barrier diodes and the heterojunctions. Deep level transient spectroscopy appears to be well suited for determining trapping states in ZnSe provided the material has a low enough resistivity.


well described. The objective of this study was to examine CSHCN access to DME or therapy services by (1) identifying the prevalence of unmet need, (2) determining the sociodemographic and diagnostic characteristics of CSHCN with unmet need, and (3) identifying potential barriers to care. Study Design: A cross-sectional study utilizing secondary analysis of the 2009–2010 National Survey of Children with Special Health Care Needs (NS-CSHCN). Study Participants and Setting: The NS-CSHCN is a nationally representative randomly selected telephone survey that includes data collected on 40 242 CSHCN between the ages of 0–17 years. We examined the data of participants responding to survey questions regarding access to DME and therapy services. Materials/Methods: Primary outcome measures were unmet need for DME and unmet need for therapy services in the prior 12 months, or since birth if the child was under 12 months of age. The NS-CSHCN defined DME as nebulizers, blood glucose monitors, hospital beds, oxygen tanks, pressure machines, and orthotics. Therapy services included Physical, Occupational, or Speech Therapy. Population characteristics are reported as weighted number (n) and percents. Age categories corresponded to eligibility criteria for early intervention and school support programs. Chi-square analysis was performed to determine statistical significance of associations with the primary outcome measures. Results: Age, spoken language, diagnosis and insurance characteristics were associated with unmet need for both DME and therapy services (Table 1). Greater prevalence of unmet need for therapy services was present across all categories. Families providing caregiving at home or unable to work were more likely to report unmet need for DME or therapy services (Table 2). Among parents reporting unmet need for therapy services, 19.6% stated this was due to cost, 12.5% that therapies were not available in the area, 9.7% were unable to get an appointment, 6.7% reported lack of insurance, and 2.4% stated they did not know where to go for services. Conclusions/Significance: These recent national data indicate that a minority of CSHCN overall have unmet needs for DME (11%) or therapy services (23%). Families of children under 8 years of age and non-English speakers are more likely to report unmet need and are therefore potential target populations for intervention. Compared to other diagnostic groups, children with diagnoses of CP and muscular dystrophy are much more likely to report unmet need for DME. Cost and family caregiving requirements are potential barriers associated with perceived unmet need for services.

Tooth transposition is the positional interchange of two adjacent teeth or the development or eruption of a tooth in a position occupied normally by a non-adjacent tooth. It has a reported incidence of 0.4% of the population and is more common in females. Canine–premolar transposition is the most common presentation, occurring more frequently in the maxilla.2 A 17-year-old female presented with an unerupted left maxillary canine in complete transposition with the maxillary left first premolar. Orthodontic treatment to correct the malocclusion and the transposition was complicated by gingival recession, which in turn was treated with corrective periodontal surgery. Clinical Relevance: This case report demonstrates the risk of localized gingival recession in the orthodontic management of canine–premolar transposition cases, even when opting for a less hazardous treatment plan. Most importantly, it highlights the importance of an interdisciplinary approach to patient care.

A new monomer containing amide linkages, N,N′-bis(4-phenoxybenzoyl)- p-phenylenediamine (BPBPPD), was prepared by condensation of p-phenylenediamine with 4-phenoxybenzoyl chloride in N,N-dimethylacetamide (DMAc). A series of novel copolymers of poly(ether ketone amide) (PEKA) and poly(ether ketone ketone) (PEKK) were synthesized by electrophilic Friedel—Crafts solution copolycondensation of isophthaloyl chloride (IPC) with a mixture of BPBPPD and diphenyl ether (DPE), over a wide range of BPBPPD/DPE molar ratios, in the presence of anhydrous aluminum chloride and N-methylpyrrolidone (NMP) in 1,2-dichloroethane (DCE). The polymers obtained were characterized by different physico-chemical techniques. The crystallinity, melting temperatures, and glass transition temperatures of the polymers increased with increase in the BPBPPD content in the reaction system due to the existence of hydrogen bonding in the polymer, the copolymers with 50—90 mol% BPBPPD were semicrystalline. The copolymers with 50—60 mol% BPBP...


Synopsis : The JT-60SA cryogenic system with a refrigeration capacity of 9.5 kW at 4.5 K consists of Refrigerator Cold Box (RCB) and Auxiliary Cold Box(ACB). The RCB provides cold helium to the ACB, high-temperature superconductor current leads, and an 80 K thermal shield. The ACB supplies supercritical helium at 4.4 K / 0.5 MPa by cold helium circulation pumps to a superconducting magnet system through the heat exchangers in a liquid helium tank. In a tokamak type fusion device, superconducting coils, CS and EF, are operated as dynamically controlling their transport currents to sustain plasma operation. Hence the heat load variations caused by AC losses could disturb the operation of the cryogenic system. The JT-60SA cryogenic system has an active control mechanism to mitigate a substantial dynamic of heat load for the stable operation of the warm helium compressors and turbines. During the commissioning of the cryogenic system, the active control mechanism demonstrated a stable operation of the cryogenic system. A cool-down operation of the cryogenic system started in October 2020. This paper reports the specifications of the cryogenic system, a result from a control test for variable heat load, and thermal analysis result at toroidal field coil operation.


Paradigm shift in architectural design initiated by new technological developments has replaced conventional processes of architectural model design with dynamic transformative ones. This paper examines some of the recent developments in the architectural design through analysis of selected architectural projects and their models. The focus of the paper is the analysis of some new approaches in architectural design through implementation of digital design and novel digital fabrication technologies.


Background and Hypothesis: High-energy fractures associated with severe soft tissue injury have a significant incidence of delayed or non-union. The soft tissue envelope may adversely contribute to the healing of a fracture, not only in stripping of the periosteal blood supply, development of compartment syndrome or tissue interposition between the bone ends but also in its ability to generate an intense acute inflammatory response. Inflammation is the initiator of healing; in clinical scenarios of impaired inflammation (immune deficiency, NSAIDs, corticosteroids) healing is delayed; interestingly, in injury with excess inflammation (CVA, MI) healing is also delayed. Would the inflammatory response following high-energy fractures contribute beneficially or adversely to the healing of the underlying fracture? Using an in-house murine femoral fracture model which reliably demonstrated features of delayed fracture healing when associated with a severe overlying muscle crush injury we proposed these hypotheses: That fracture callus with overlying muscle crush would contain raised expression of acute inflammatory cytokines (IL-1β, IL-6 and TNF-α). That application of locally applied blocking antibodies to these inflammatory cytokines might negate excessive cytokine release and modulate fracture healing in this model. Methods: Total RNA was extracted from normal fracture callus (FO) and muscle crush fracture callus (MC) at day 2, day 4 and day 8. Semi-quantitative RT-PCR was used to compare IL-1β, IL-6 and TNF-α mRNA expression. Histomorpometric analysis of ICC stained sections of the FO and the MC groups was used to estimate IL-1β, IL-6 and TNF-α protein expression within the callus. Positively staining areas for the cytokine within the callus were a semi-quantified and compared between groups. Finally, blocking antibodies to IL-1β and TNF-α were injected into MC fracture callus at day 0, 4 and 8. Control MC group had vehicle only injected. Fracture healing was measured using radiological, histomorphological and biomechanical outcome measures. Following a pilot dosing experiment, the effect of blocking antibodies on fracture healing was compared between MC and MC with antibody groups. Results: The MC group IL-1β mRNA expression was significantly higher than FO at day 4 and day 8 (p=0.05). ICC for IL-1β protein expression was higher on day 4 and on day 8 in the MC group, significant at day 8 (p=0.03). TNF-α mRNA expression in the MC group at day 8 was significantly higher than the FO group (p=0.05). ICC for TNF-α protein in the MC group peaked at day 8 and was significantly higher than the FO group (p Injection of anti-TNF-α antibodies into MC mice caused more new bone formation on day 16 (p=0.03) and day 24 (p=0.06), stiffer calluses at day 24 (p=0.01) and faster fracture gap obliteration at day 16 (p=0.05) and day 24 (p=0.001). IL-1β blockade had slightly less effect, more new bone formationd ay 16 (p=0.01) and day 24 (p=0.03), slightly stiffer (p=0.08), but no significant difference in fracture gap obliteration from controls. Conclusion: The effect of muscle crush around the fracture callus was to increase and prolong the expression of inflammatory cytokines with the callus. The effect of blocking these excessive inflammatory cytokines in our model was to improve fracture healing. Excessive inflammatory cytokines (IL-1β, IL-6, TNF-α) in bone impair new bone production by osteoblasts, inhibit the recruitment and differentiation of mesenchymal precursors and promote osteoclastogenesis. The mechanism of action of blocking antibodies may be due to inhibition of the antiosteogenic effects of these cytokines.


Cell-free extracts of Neurospora crassa mycelium catalyze the methylation of l-histidine to form hercynine (histidine betaine). The partially methylated compounds, α-N-methyl-l-histidine and α-N,N-dimethyl-l-histidine, are also methylated by the same enzyme preparation to form hercynine. All three methylation reactions are stimulated by the addition of S-adenosylmethionine.


The Global Health Workforce Network (GHWN), formerly Global Health Workforce Aliance, is a broad term which challenges the problems surrounding a severe health workforce shortage. In 2006, the World Health Organization (WHO) calculated that to attain a high coverage of skilled birth
 attendance, there was a minimum requirement of 2.28 physicians, nurses and midwives for every 1,000 people in a population. However, statistics prepared by WHO back over a decade ago suggested that 57 countries around the world fell below this threshold, this meant that an additional 4.3 million
 health workers were needed to fill the shortage. Fast forward to 2019 and there still appears to be a significant shortage. For that reason, there have been many investigations into how best to solve this problem – one that will only get worse as the global population continues to grow.
 One strategy that has been identified is interprofessional education (IPE), which is a pedagogical approach that aims to prepare health professions students by placing them in a collaborative team environment. The idea is relatively straightforward: improve the overall quality of healthcare
 by putting students from two or more professions in health and social care together, so that they can each learn from the others and cultivate collaborative practice (CP), which may also contribute to patient safety.


The invention provides a distributed structure of a horizontal section of a multi-branch horizontal coal bed methane well, which comprises a main borehole, and branch boreholes connected to the main borehole. The main borehole comprises a first main borehole and at least one second main borehole; the second main borehole is a branch of the first main borehole; and in the first main borehole and the at least one second main borehole, the outer sides of two branch main boreholes positioned on the outermost parts are respectively provided with a group of branch boreholes. In the distributed structure of the horizontal section of the multi-branch horizontal coal bed methane well, by increasing the number of the main boreholes, the branch boreholes originally connected to the two sides of the same main borehole are distributed to the two sides of the two main boreholes, the pressure of the main boreholes serving as drainage and pressure release channels is reduced, and the footage of the main boreholes per se is fully utilized. Meanwhile, the risk that the main boreholes are damaged, complicated or blocked is dispersed. The footage of the tail end of the horizontal section of the horizontal well is relatively reduced, and the probability that the footage of the tail end of the horizontal section of the horizontal well is actually invalid when the main boreholes are declined due to terrain declination is reduced.


Nowadays the dual banking system in Malaysia has enable banks to offer two forms of home financing method, the Islamic home financing and the convensional home loan. As we know a house is a everyone needs. They will get by all means by purchase it, renting or build the house themselves. Islamic home financing product is one of the sources that generate profits for the local and foreign Islamic bank in Malaysia. Thus, very few people can afford to purchase a house on a cash basis. As muslim consumers, it is important for them to choose wisely on their financing. This study attempts to analyse the practice of Islamic home financing product base on debt in Malaysia since 2000 till 2016. The study is motivated by few shortcomings of current Islamic home product as well as an increasing the number of shariah instrument contracts among Islamic banking in Malaysia. Islamic home financing in Malaysia can divided into two types, which is debt and equity. Bai bithaman ajil (bba) is the most marketable mode of home financing in Malaysia since 1983 but nowadays, many Islamic banks in Malaysia was accepted musyarakah mutanaqisah (mm) and tawarruq as an alternative to bai bithaman ajil. This study uses a qualitative approach. The paper would survey the practice on Islamic home financing in Malaysia base on debt since 2000 until 2016.


A spin-dependent eikonal amplitude for the scattering of two fermions by vector-meson exchanges is extended to include spin dependence due to pseudoscalar exchanges as well. The result is applied to elastic p-p scattering by using a primitive, energy-dependent Chou-Yang model augmented by pion exchange. The spin dependence introduced dramatic energy dependence resembling that observed.

Conclusion Desocclusol is a new and effective solvent of root canal filling material.


Hyperlipidemia contributes significantly in the manifestation and development of atherosclerosis and heart disease. Although synthetic lipid‑lowering drugs are useful in treating hyperlipidemia, there are number of adverse effects. Therefore, the current interest has stimulated the search for new lipid‑lowering agents with minimal side effects from natural sources. The Purpose of this study was to examine the lipid lowering capability of aqueous: ethanol (1:1) extract of Carissa carandas in high fat diet induced hyperlipidemic rats. A highly significant increase in the weight of high cholesterol diet rats was observed when compared with control group (P<0.01). The extract caused a significant reduction in body weight, Cholesterol, Triglycerides, HDL and LDL in hyperlipidemic rats. Histopathological changes induced by high cholesterol diet were also significantly reduced by the extract. The activity of ethanol and water extract of C. carandas was comparable to that of atorvastatin.


The silent casualty: documentaries and the environmental impact of war - Talks about the devastating impact war has on the environment: an issue that not always has been fully taken into consideration. Nonetheless, the interest of historians and film-makers for the topic has been increasing steadily over time. The forests and fields destroyed by the Americans in Vietnam, the oil wells set on fire by the Iraqis in Kuwait, the Yugoslav factories bombed by Nato air raids are just some of the possible examples of war-related environmental disasters. This article aims at showing some striking cases as they are depicted, beyond traditional historiography, in documentary films and at explaining the main issues at stake from the professional historian's point of view. Keywords: Documentaries, War, Environment, Vietnam, Kuwait, Kosovo. Parole chiave: Documentari, Guerra, Ambiente, Vietnam, Kuwait, Kosovo.

In the pre-hospital environment, attending an older person can pose many challenges, including a lack of a detailed history, polypharmacy and co-morbidities, as well as a lack of out-of-hours support to name but a few. These challenges are enhanced further when the patient is cognitively impaired by syndromes such as dementia. There appears to be very little research available into how the pain of older people with dementia is assessed and managed by paramedics. This article highlights a literature review that was carried out to explore the evidence base and possible implementation of the Abbey Pain Scale, with the view of conducting a study in the near future. Particular focus is made on the education and training required to implement the tool, other environments where it has been adopted, as well as benefits and limitations.


A convenient and simple three-component synthesis of substituted pyridylacetic acid derivatives is reported. The approach centers on the dual reactivity of Meldrum's acid derivatives, initially as nucleophiles to perform substitution on activated pyridine-N-oxides, then as electrophiles with a range of nucleophiles to trigger ring-opening and decarboxylation.


Bifunctional organic compounds have significant applications particularly in polymer science. Herein, new dipropargyl sugar derivative has been synthesized staring from D-mannose. In the first step, mannose diacetonide was prepared from commercially available D-mannose and acetone in the presence of H2S04. Then, the isopropylidene was extended at C-2 via aldol condensation using formaldehyde in the presence of base. Next, Williamson etherification was followed to synthesize the required dilkynyl compound through the treatment of the 2-C branched sugar with propargyl bromide in the presence of Na0H as a catalyst. All synthesized derivatives were identified utilizing NMR and HRMS.


We propose a new algorithm for the IQ imbalance estimation and equalization of an Orthogonal Frequency Division Multiplexing (OFDM) system in the presence of a Carrier Frequency Offset (CFO) and of a dense multipath environment. Our algorithm has a low complexity and needs a single pilot symbol. Through numerical simulation and in the context of quick estimations of front-end non-idealities, our algorithm is shown to outperform conventional approaches for sensible values of IQ imbalance and CFO.


"QingZhen" is the key point of Zhang Xuecheng's literature theory. The essential meaning of "Qing" is that the organization and the style is pure and consistent; the coherence is clear and not disorderly; the language is concise. Zhang's "Qing" theory is the result of his inheriting predecessor's theory and his unique understanding of literature as a historian.


Our study sought to optimize the identification and investigate the impact of comorbidity in cancer patients using routinely collected hospitalization data.


This paper proposes a backstepping integral sliding mode controller (BISMC) based on the partial feedback linearization (PFBL) of the detailed model of synchronous generators (SGs) in simple power networks. The proposed scheme is designed to obtain the excitation control input using the detailed model of SGs in a simple power system where the PFBL is used to simplify the model. The BISMC is employed on this simplified model to ensure the transient stability during large disturbances. The inherent property of the BISMC tackles the chattering and overcomes the parameter sensitivity problem of the PFBL scheme. Simulation studies are conducted under different operating situations to justify the effectiveness of the proposed PFBL-BISMC over a partial feedback linearizing controller (PFBLC).


OBJECTIVE: We investigate whether qEEG measures could identify differences between MCI and non-MCI patients with PD.
BACKGROUND: MCI is diagnosed clinically based on the results of a large standardized set of cognitive tests (alertness, executive functions, visuo-spatial abilities, episodic and working memory). Certain qEEG parameters are associated with dementia.
DESIGN/METHODS: High-resolution 256-channel EEG (EGI Netstation 300, sampled at 1kHz) were recorded in 53 PD patients (MCI/non-MCI: 41/12 | age: 67.2±8.4 | female/male: 19/34 | Hoehn-Yahr: 25%: 0.0 - median: 2.0 - 75%: 2.5). The data was pre-processed semi-automatically and relative power in 5 frequency bands (delta, theta, alpha1, alpha2 and beta) was calculated globally and for 10 regions. Additionally, peak and median frequency were determined. qEEG results were compared between groups by using permutation tests on t-statistics to correct for multiple comparisons within the different frequency bands. Effect sizes of all variables were calculated.
RESULTS: Out of all 57 examined variables, lower mean values were observed in global alpha1 band power and of alpha1 power in five regions (left hemisphere: frontal, central, temporal, occipital; right hemisphere: temporal, corrected p<0.05), differentiating between non-MCI and MCI groups. Effect sizes were high and ranging from 0.79 to 0.87. Peak frequency was 8.25±1.79Hz and did not differentiate between the groups.
CONCLUSIONS: Reduction of alpha1 band power, particularly in the left hemisphere, is associated with MCI in PD patients. The results might be used to design automatic diagnostic methods that would complement the time-consuming cognitive tests without the drawback of training effects in repeated neuropsychological testing.

Open configuration is proposed to assist companies in configuring products that can meet both unforeseen and predefined customer requirements. This study investigates the open configuration process and proposes an approach based on cloud computing. Based on a cloud, the open configuration process includes three sub-processes: new component specification, constraint processing, and component modification and refinement. This study sheds light on the details of new component specification sub-process. Laptop computer open configuration is used to demonstrate how new components are specified.


We recently proposed a novel realization of Kondo physics with ultracold atomic gases and illustrated that a mixture of 40K and 23Na atoms has suitable properties for the generation of a Kondo-correlated state with experimentally accessible scales. This system fortuitously satisfies rather special conditions. Here we discuss an alternative realization based on confinement induced resonances which could also be applicable for other mixtures. We first explain the general principle of how to engineer the Kondo correlated state like this. Then we present results for local spectral functions from numerical renormalization group (NRG) calculations for the appropriate effective Anderson impurity model and also predict the experimentally measurable radio frequency response.

There was statistically significant correlation between knowledge of women and socio-demographics, level education and women had history of placenta previa (p<0.05).
Conclusion: Women participants at Mosul city had poor knowledge level about placenta previa.


Abstract The objective of this study was the classification of a Mediterranean humid mesothermal area (Csa) of central Macedonia into land systems, using LANDSAT images (1:250000 in scale). The information obtained was combined with field survey work in order to study the wide range of natural environmental conditions of the area. In general the survey area includes mountainous ridges up to 2054 m, hills up to 300m, plains either near flat or gently undulating and tectonic fill valleys about 150 m in elevation. During the survey the area was subdivided into 31 land systems according to distinctive combination of physiography, soils and vegetation. The land-system map produced by this method is of considerable interest because it provides the framework for more detailed geological, geomorphological, soil and land-use studies.


In the present paper, we propose a new modulation called continuous-phase parallel-combinatory high-compaction multicarrier modulation (CPPC/HC-MCM). The CPPC/HC-MCM employs the technique of continuous phase modulation (CPM) and avoids the amplitude gaps between two successive signals to enhance the property of spectral efficiency of conventional PC/HC-MCM. The results show that the CPPC/HC-MCM achieves a smaller bit-error rate (BER) than conventional (unmodulated) PC/HC-MCM for large signal-to-noise ratio at a common spectral efficiency less than about 0.33.


Background: Occupational safety of Health Care Workers (HCWs) is often neglected in low-income countries in spite of the greater risk of infection due to higher disease prevalence, low level awareness of the risks associated with occupational exposure to blood, inadequate supply of PPE and limited organizational support for safe practices. Objectives: To determine the prevalence of occupational accidents among HCWs in primary health facilities in Enugu Metropolis, Nigeria. Methods: The study was a descriptive cross-sectional design that used a mixed method technique. The qualitative data was collected using an In-Depth Interview (IDI) guide while the quantitative data was collected with a pre-tested self-administered questionnaire. Manual content analysis was done for the qualitative data while the quantitative data was analysed using SPSS version 22 with the significance level placed at p<0.05. Results: The proportion of HCWs that have had exposure of their mucous membranes to blood/body fluids in the past 6 and 12 months were 17.5% and 27.0% respectively while the mean number of exposures were 2.94±2.388 and 3.19±2.875 respectively. A similar proportion had needle stick and sharps injury in the past 6 (16.5%) and 12 (22.0%) months while the mean number of injuries were 2.73±1.875 and 2.98±2.074 respectively. The major circumstances under which they obtained injury were while giving injection and breaking injection ampoule. Emergent themes from the IDI were recapping of needles and giving injections Conclusion: The prevalence of occupational accidents is still high considering the dangers associated with these accidents.


Title of Thesis: VEHICLE HANDLING, STABILITY, AND BIFURCATION ANALYSIS FOR NONLINEAR VEHICLE MODELS Vincent Nguyen, Master of Science, 2005 Thesis directed by: Dr. Gregory A. Schultz Department of Mechanical Engineering Vehicle handling, stability, and bifurcation of equilibrium conditions were studied using a state vector approach. The research provided a framework for an improved method of vehicle handling assessment that included non-linear regions of performance and transient behavior. Vehicle models under pure lateral slip, constant velocity, and constant front steer were developed. Four-wheel, two-axle vehicle models were evolved from simpler models and were extended to include vehicle roll dynamics and lateral load transfer effects. Nonlinearities stem from tire force characteristics that include tire force saturation. Bifurcations were studied by quasi-static variations of vehicle speed and front steer angle. System models were expanded, assessing overall stability, including vehicle behavior outside normal operating ranges. Nonlinear models of understeering, oversteering, and neutral steering vehicles were created and analyzed. Domains of attraction for stable equilibrium were discussed along with physical interpretations of results from the system analysis.


This essay meditates on the poet Antonio Barolini's movement "between two worlds" — Italy and America, yet also the sacred and the secular, as well as poetry and prose. For Valesio, Barolini teaches us to dwell in this liminal space with a certain lightness that he brings to bear on what is, increasingly, a dominant aspect of human experience.


"The End of our Foundation is the knowledge of Causes and secret motions of things; and the enlarging of the bounds of Human Empire, to the effecting of all things possible." Thus a senior fellow of Salomon's House, Francis Bacon's idealized scientific institution, reveals the ultimate aims of his order. Though this description may have struck most readers of New Atlantis as marvelously Utopian, the vision soon bore fruit. By the late seventeenth century, it had stimulated the founding of the Royal Society. By the late twentieth century, it stands as a provocative image of the state of contemporary science. The development of modern science cannot, of course, be traced or attributed to any single progenitor. Yet, Bacon can be credited with having clearly and explicitly formulated a schema for the advancement of knowledge that is immediately recognizable to anyone immersed in the scientific worldview of Western culture. It is in this sense that I take


Objective
To evaluate the value of intravascular interventional embolization in the emergency treatment of patients with hemodynamically unstable pelvic fracture.

Methods
The retrospective analysis was made on the medical records of 45 cases treated from October 2012 to December 2014. There were 27 male and 18 females(39.2±10.3) years (range, 28-54 years). Time from injury to admission was within 3 h. Injury severity score (ISS) was (25.3±8.1)points. The pelvic fracture included 32 cases of Type B and 13 Type C according to Tile classification system. After admission, anti-shock treatment and pelvic immobilization with the belt or external fixator were performed, and emergent intravascular interventional embolization was used to stanch bleeding after the bleeding of other organs was excluded. Vascular intervention, post-treatment vitazl signs and prognosis were evaluated.

Results
Time from admission to interventional therapy was 1.2-2.7 h[(1.9±0.8)h]. Time of interventional treatment was 1.6-3.2 h [(2.3±0.6)h]. Of the 45 cases, contrast extravasation was seen in 38 cases, abnormal vascular morphology in 5 cases, no obvious bleeding in 1 case, and contrast extravasation in the angiographic venous phase in 1 case. Among the 38 cases of contrast extravasation, the offending vessels involved were internal pudenda artery (26 cases), obturator artery (16 cases), superior gluteal artery (4 cases), inferior gluteal artery (4 cases), inferior epigastric artery (1 case) and external iliac artery (1 case), but 8 cases were noted to have two offending vessels and 1 case had delayed bleeding. Of the 45 cases, the hemostatic effect was good in the early stage. After the interventional embolization therapy, the heart rate was (105.2±14.8) beats/min, arterial pressure was (79.0±10.6)mmHg, central venous pressure was (5.1±0.8)cmH2O, and shock index was 1.1±0.5, showing improved vital signs postoperatively (P<0.05). Four cases died mainly due to the multiple organ failure. One case had abdominal distention aggravated 3 days after operation, which were confirmed to be bleeding in the branch of external iliac artery, and the symptom was alleviated after embolization therapy. Forty-one cases survived with ICU length of stay of (14.5±5.4) d, hospitalization time of (35.2±12.8) d and medical expense of (96, 755.3±20, 568.1) CNY.

Conclusion
In the emergency treatment of patients with hemodynamically unstable pelvic fracture, the intravascular interventional embolization has become an important measure of comprehensive treatment that allows fast and mini-invasive procedure hemostasis, and deserves clinical promoting.
