Two studies, both originating from a larger psycholexical study in Serbian language, are presented here. Two questionnaires, Lexi and PL have been constructed in the psycholexical study. The questionnaires differ by the formulation of their respective items: while the items of the Lexi contain adjectives, the items of the PL are in the form of statements. The first study presented in this paper examines the latent structure of the Lexi questionnaire, while the second one deals with the latent structure of the PL. In both studies, principal component analysis was applied, and the number of components to be retained in the analysis was determined according to the Scree criterion. Also, Promax rotation was applied in both studies. Seven components which were extracted in the first study have been interpreted as Negative Valence, Negative Emotionality, Aggressiveness, Conscientiousness, Positive Emotionality, Positive Valence and Openness to Experience. The content of these dimensions is obviously similar to the dimensions of Tellegen and Waller's Big Seven model. In the second study, five components were extracted, and interpreted as Sociability, Anxiety, Aggressiveness, Activity and Impulsivity. The content of the dimensions extracted in the second study corresponds with the dimensions of Marvin Zuckerman's Alternative Five - Factor Model.


OBJECTIVE:To evaluate the efficacy of pharmaceutical intervention on perioperative non-rational use of drugs in an effort to promote clinical rational use of drug.METHODS:500 medical records of surgical patients collected in Harbin No.242 Hospital during July-Dec.period of 2011 were assigned to non-intervention group,and another 500 medical records of surgical patients collected in the same hospital during Jan.-Jun.period of 2012 after implementation of a series of pharmaceutical intervention measures were assigned to intervention group.The prophylactic use of antibiotics was compared between the two groups.RESULTS:The intervention group showed great improvement compared with non-intervention group with regard to the rate of antibiotic use,choice of antibiotics,and time and duration of administration of antibiotics.The rate of antibiotic use decreased from 84.80%(424/500) to 29.60%(148/500);the first generation cephalosporins were chosen predominantly and the rate of preoperative standard prophylactic use of antibiotics peaked to 94.59%(140/148).CONCLUSION:Clinical pharmacists' pharmaceutical intervention on perioperative use of intensified clinicians' consciousness on clinical rational use of antibiotics,improved the level of rational use of drugs,significantly reduced the rate of perioperative use of prophylactic antibiotics and the duration of administration of antibiotics.


To the Editor: The constituent epidermal, melanocytic, and pilar elements of Becker's nevus may demonstrate a spectrum of hamartomatous changes that may be congenital or acquired (1). We report a case of multiple leiomyoma cutis with mottled pigmentation and open comedones, probably representing the extreme form of Becker's nevus. Case Report: A 22-year-old male presented with a 10 year history of painful multiple swellings over the left side of the back. The number of lesions and pigmentation suddenly started increasing about 3 years previously. A 15 x 20 em area over the left side of the lumbar region crossing the midline of the back (Fig. 1) was involved with background freckle-like pigmentation and blackheads (open comedones). These were topped by 0.5 to 2 em sized, multiple, tender, skin-colored, soft to firm papular and nodular lesions. Histopathological examination of multiple sections of the representative skin lesion showed an ill-defined tumor with overlying epidermis (Fig. 2). The tumor was composed of interlacing bundles of smooth muscle fibers, which had eosinophilic cytoplasm and blunt-edged nuclei. Masson trichrome stain stained these muscle fibers densely red and the collagen blue. The epidermis showed a slight increase in the basal layer pigmentation. No nevus cells were seen in the dermis. The diagnosis of leiomyoma cutis with Becker's nevus was based on the above findings. Comments: The smooth muscle bundles in Becker's nevus, indistinguishable from those seen in smooth muscle hamartoma, have led to some controversy about the relationship of these two entities (2). Clinically, smooth muscle hamartoma presents as an asymptomatic single patch, most commonly in the lumbar region (3). It may present at birth or arise in childhood Or early adulthood (2, 4). Usually, there are small, follicular papules throughout the patch, 719


We study the features of the rigidity power spectrum of the 27–day variation of the galactic cosmic ray intensity by neutron monitors experimental data in the minima epoch for different polarity periods of solar magnetic cycles. We construct theoretical models based on the 3-D transport equation assuming that the heliolongitudinal changes of the interplanetary magnetic field turbulence and the diffusion coefficient can be considered as the possible sources of the 27-day variation of the galactic cosmic rays intensity.


The concept of responsibility to protect is a modern concept in international relations and international law. Its evolution started in 2001 within the Project of the International Committee for the Intervention and State Sovereignty. It was welcomed by the UN being elaborated and applied in several occasions. In the paper, the author explores the concept of responsibility to protect from two aspects. One aspect is a genesis of the concept and its normative framework. The author presents all documents on the R2P adopted by the UN General Assembly, UN Security Council, UN Secretary General as well as the debates on the issue. The other is a critical and analytical elaboration of the issue concerned. The analysis is contemplated in terms of both theory of international relations and international public Law. Its practical aspect is elaborated by using the Syrian crisis as an example.


Dr. Finlayson, in his preliminary remarks, said the subject was one which could well be brought before such a society as the Pathological and Clinical, while the actual demonstration of the books brought the communication within the scope of this Society. He proposed to deal chiefly with what might be termed the classics of pathological anatomy rather than with works of later date dealing with modern pathological histology. He thought that works on the latter subject, being published within comparatively recent years, did not possess such historic interest as those he had mentioned.


We propose and analyze a mechanism for inducing spin Hall currents in ordinary (1H phase) monolayer transition metal dichalcogenides (TMDs) due to the nonlinear process of optical rectification. The photo-induced spin current is proportional to the light intensity, and originates from the intrinsic spin–orbit coupling in TMDs. The spin current spectrum is strongly influenced by electron–hole interactions, i.e. excitonic effects, analogous to the optical absorption. Remarkably, excitons change the temperature dependence of the induced spin current, to the point that the current direction can even be reversed by varying the temperature. This peculiar excitonic behavior is shown to emerge from the relative strength of two distinct mechanisms contributing to the optical response, i.e. a purely interband part and a mixed inter/intraband contribution. Our findings pave the path to the generation of dc spin currents in ordinary TMDs without external static electric or magnetic fields.


Simulink/Stateflow is a popular commercial model-based development tool for many industrial domains. For safety and security concerns, verification and testing must be performed on the Simulink/Stateflow designs and the generated code. The authors present a test generation approach for Simulink/Stateflow by its reduction to reachability in a hybrid automaton, with its locations representing the computations of the Simulink/Stateflow model, and edges representing the computation-succession. A novel reachability resolution method is presented based on the refinement of the hybrid automaton such that the reachability is reduced to the reachability in the underlying graph (without the dynamics), whenever the refinement step terminates. The approach yields a technique that is effective in terms of achieving test coverage and efficient in terms of test generation time whenever the computation of each time step can be analytically solved for an arbitrary number of repetition. The approach is also applied on defect-detection and requirements-satisfaction, and illustrated through application to a bounded counter and a cyberphysical system of a thermal control unit.


though it remains unprovable, and I confess that I find it difficult to imagine Robespierre regaling the Convention with carefully crafted puns. Like André's image of a subsumed homosexuality in the act of killing the King, it seems over-contrived and far removed from the immediate historical context. Indeed, like various other ideas cleverly analysed in these pages, it might seem to fit better into the genre of belles-lettres than of history, though to admit that is merely to betray this reviewer's own concept of revolution and approach to politics.


Nowadays, worldwide public utility services providers feel the necessity of new flexible and scalable solutions aimed at managing their distribution networks and services. This is fundamentally due to the continuously technological evolution of distribution network infrastructures that impacts deeply on the software in charge of handling the services supply chain management. The purpose of this paper is to present an innovative system aimed at defining a new approach to resource inventory. This approach is designed both to reduce the influence of infrastructure evolution and to enable value-added services performed by autonomous intelligent agents. Based on the integration of semantic web technologies and agents paradigm, the systempsilas mission is to define a new ontology-based model for resource inventory. Moreover, the system defines a new behavioral model enabling software agents to effectively react to the network environment in which they are embedded.


Prior to receiving the grant, Utilitip was faced with an idea that truly worked, however only a very limited line of component parts would fit various types of chain saws on the market. It also suffered from a severe problem when engaged in the ground of soil penetrating the saw chain area, thus eliminating one of the major benefits of keeping the chain sharp. Consequently, the grant funding was directed towards extending the tooling capabilities to produce parts for a much wider variety of chain saws that are on the market, and further by developing an effective flexible soil shield to prevent abrasive soil entry into the saw chain. Utilitip was able to complete a full set of design for a wide variety of large and small chain saws. This incorporated a design and fabrication of a small Utilitip, as well as a small anti-kickback device. In addition, tooling was also further developed for the large Utilitip and the large anti-kickback device. Accordingly, multiple tools are available for all combinations, as well as back-up provisions. Utilitip, Inc. invented a special, flexible attachment to be glued and/or molded to the tip guard. The soil shield prevents abrasive soil from coming intomore » the chain area. In addition, it allows a flexible arrangement to allow the chain saw to be released from brush without binding. Otherwise, a larger, rigid soil shield would hold or restrict the saw in heavy brush. The rubber shield will flex out of the say and reduce, if not eliminate, this harmful binding.« less


Astrocytes are increasingly viewed as active participants in the moment-to-moment functioning of the brain. They respond to neural activity ([Beierlein and Regehr, 2006][1]), affect network excitability ([Pascual et al., 2005][2]), and regulate blood flow ([Takano et al., 2006][3]). One structurally


Introduction:
 Long-term monitoring for atrial fibrillation (AF) is recommended in patients, who have experienced a cryptogenic stroke (CS). Clinical trials have identified AF in ~30% of patients after 3 years of continuous monitoring with insertable cardiac monitors (ICMs).

 Hypothesis:
 In a real-world analysis from a large academic healthcare system, we sought to evaluate a CS population with ICMs and a) determine the yield of AF and subsequent initiation of anticoagulation; and b) identify the presence of other arrhythmias.

 Methods:
 We evaluated all CS patients who had received an ICM between October 2014 and April 2020. We manually reviewed all stored electrocardiograms that were automatically labeled as AF by the ICM and adjudicated them as either a) AF or b) other cardiac arrhythmia including premature atrial contractions (PAC), premature ventricular contractions (PVC), supraventricular tachycardia (SVT), or nonsustained ventricular tachycardia (NSVT).

 Results:
 A total of 84 CS patients with ICMs were included: 51% men, mean age 63 years, and mean CHA

 -VASc 4.1. Over a median follow-up duration of 15.7 months, there were 34 patients (40% of the cohort) who did not have any AF alerts. In the remaining 50 patients, there were 960 stored electrograms that were adjudicated. Only 154 recordings from 16 patients (19% of the entire cohort) were adjudicated as AF. Oral anticoagulation was initiated in all these patients with adjudicated AF. The remaining tracings, which had been automatically categorized by the ICM as AF alerts, represented 34 patients (40% of the cohort). These patients had other arrhythmias including frequent PACs or PVCs, SVT, or NSVT.

 Conclusions:
 Compared to clinical trials, our real-world assessment suggests that the yield of AF following CS is lower - approximately 20%. Our findings highlight the importance for reviewing device tracings given the high rates of false positive for AF. Further research to refine AF detection algorithms in ICMs is needed.


The paper presents a technique of enhancing the gain of a patch antenna. The enhancement is realized by putting a dielectric layer on top of the patch. The analysis is performed using the finite-difference time domain method, where Yee's rectangular mesh is used with Liao's second order absorbing boundary condition (Taflove, A. "Computational electrodynamics", Artech House, 1995). The assumptions used in the analysis are as follows: the bottom (substrate) and top dielectric layers are lossless; the ground plane is of infinite extent; the patch is infinitesimally thin. As the top dielectric layer thickness, B/sub top/, increases, the input impedance shows oscillatory variations, with a period slightly larger than one-half of the guided-wave length of a plane wave propagating in an unbounded dielectric material. It is also found that, as B/sub top/ increases, the radiation pattern becomes narrower and the gain reaches a maximum value. However, as B/sub top/ further increases, the gain decreases due to rising side-lobe levels. A gain increase of 7.2 dB is obtained at B/sub top/=1.48/spl lambda//sub 8/ for /spl epsiv//sub r/=2.07.


In previous studies we demonstrated that CT7 (MAGE-C1), a member of the type I MAGE family of Cancer-Testis antigens, was expressed in 82% of primary multiple myeloma specimens. Higher percentages of CT7-expressing cells were correlated with abnormally elevated plasma cell proliferation in these patients, and CT7 was co-expressed in proliferating myeloma cells. Therefore, a tumor vaccine targeting CT7 may preferentially eliminate proliferating myeloma cells, resulting in long-term cures. The type I MAGE were originally identified because they elicited cellular immune responses in melanoma patients whose tumors expressed these antigens. These data suggest the hypothesis that CT7 expression in myeloma cells may similarly elicit T cell immunity in myeloma patients. To test this hypothesis, we examined lymphocytes from myeloma patient bone marrow, the tumor microenvironment. Lymphocytes were isolated from myeloma patient bone marrow aspirates by magnetic bead depletion of CD138 plasma cells followed by plating to remove adherent monocyte. Bone marrow lymphocytes were then expanded by two rounds of stimulation with anti-CD3, anti-CD28 monoclonal antibody (mAb)-conjugated beads and 50 IU/ml recombinant human (rhu) IL-2. Autologous myeloid dendritic cells (mDC) served as antigen-presenting cells for this analysis; they were prepared from peripheral blood monocytes by cultivation with rhu-IL-4 and GM-CSF, then matured with a cytokine cocktail consisting of TNFα , rhu-IL-1β , rhu IL-6, and prostaglandin E2. Myeloid DC were then transduced with in vitro transcribed CT7 mRNA or positive control antigen flu matrix protein (MP) mRNA by electroporation. Negative control mDC were also mock electroporated without mRNA. The dendritic cells were then co-cultured with the expanded bone marrow lymphocytes at 1:1 and 1:20 ratios in IFNγ ELISpot assays. Positive control stimulation with the T cell superantigen Staphylococcal enterotoxin B (SEB) served to assess overall responsiveness of the polyclonal lymphocyte population. Results from four patients are shown in Table 1. Two of four patients, both diagnosed with stage IIIa disease and both expressing CT7 mRNA by RT-PCR, exhibited increases in IFNγ-secreting lymphocytes when co-incubated with CT7-transduced mDC compared to mock electroporated mDC. In contrast, one stage I patient who did not express CT7 mRNA and one stage IIIb, CT7+ patient did not show any increase in IFNγ-secreting cells in response to CT7-transduced mDC stimulation. These data indicated that CT7 expression in myeloma cells can provoke cellular immunity, and suggests that CT7-specific vaccines may boost this immunity. These ongoing studies will also characterize the antigenic T cell epitopes of CT7.


Shape memory polyurethane (SMPU), flexibly crosslinked via a polyethyleneglycol (PEG) spacer attached to its side through an allophanate group, was tested for shape memory and compared with a linear SMPU. The new SMPU was composed of 4,4′-methylenebis(phenylisocyanate) (MDI), poly(tetramethyleneglycol) (PTMG-2000), and 1,4-butanediol (BD), and included polyethyleneglycol (PEG-200) as a spacer. A second MDI, linked to the carbamate group of the first MDI, served as the connecting point for the PEG-200. Two types of SMPU, differing according to their soft segment (PTMG-2000) and linker (PEG-200) contents, were compared in mechanical and shape memory properties. In the best case, a 780% increase in maximum stress was attained without any sacrifice in strain for the new material compared with the linear polymer. In particular, the stress–strain curve showed that the PEG-crosslinked SMPU had superior tensile mechanical properties. Its shape recovery was as high as 99%, which is the best value we have measured for an SMPU. After four cyclic tests, shape recovery remained greater than 95%. Shape retention of the best SMPU remained above 93% even after four cyclic tests. Here, results demonstrating the extraordinary shape memory properties of these types of SMPU, together with differential scanning calorimetry (DSC) and infrared spectroscopy data, are analyzed and discussed.

This study examines how far women self-help groups model of development has helped empower women and whether formal and informal institutions relating to state, market and civil society have become inclusive of poor women due to women self-help groups model of development. The authors articulate that extreme poverty and widespread inequality between men and women are the main impediments to democracy and development. Further, this study suggests that as gender equality is an important factor in the development process, empowerment of women may address this issue to some extent. To sum it up, among all the women-based group models of poverty alleviation, the Self-Help Groups (SHGs) are promoted as basic entities and are federated to tackle higher order functions.

Systemic lupus erythematosus (SLE) is a devastating autoimmune disease that targets multiple organ systems. A population of non-hematopoetic stem cells, mesenchymal stem cells (MSC), are of increasing interest as a therapeutic option for autoimmune diseases such as SLE. MSCs can be derived from various sources such as bone marrow or umbilical cords. In this study we examine the efficacy of human MSCs with varying origin on disease in murine based lupus. Human MSCs were harvested from umbilical cords, healthy donor bone marrow, and lupus patient bone marrow. We showed that in MRL/lpr mice, MSCs from all sources improved survival, increased body weight, and decreased proteinuria. Glomerular IgG, but not C3, deposition is significantly decreased in mice receiving umbilical cord and healthy donor MSCs. However, MSC from lupus patients caused a significant increase in glomerular C3 and IgG. Although no differences were seen in the percentage of CD4+ or CD8+ T, mice receiving lupus MSCs experienced a 2-fold increase in the percentage of Foxp3+ cells in the spleen. These mice also experienced this percentage increase in TCRβ+, B220+, and CD138+ cells in the bone marrow. Human MSC from various origins all made an impact on the disease severity of lupus prone mice. However, these results suggest that MSCs from healthy donors or umbilical cords appear to be more effective in murine lupus than the MSCs derived from lupus patients.


We have discovered four intergalactic H II regions in Stephan's quintet, which is more than a 25 kpc projected distance from the center of the nearest group galaxy, with no apparent optical connection to it. They have MB ranging from -11.9 to -12.5 mag, colors B-R = 0.7-1.1 mag, radial velocities from 6565 to 6651 km s-1, and they are superposed onto the H I tail east of NGC 7319, with a mean radial velocity of 6610 km s-1. In addition, they have metallicities of the order of 12 + log(O/H) = 8.58 ± 0.25, which suggests that they were formed from preenriched material. We derive a mean age of 4.6 ± 0.6 Myr and a mean stellar mass of (2.9 ± 1.4) × 104 M☉ for the four objects. The masses, ages, colors, velocities, metallicities, and location of the objects suggest that they are H II regions that were formed far away from the galaxies through compression of the intergalactic H I gas by galaxy collisions.


Influence of mixing MgO additive on fluidized bed reduction of iron ore fines using simulate COREX reducing gas was investigated. Experiments were conducted at 1073 K in a visualization fluidized bed. Mixing MgO additive was carried out using powder method and solution method. It was found that mixing MgO into ore fines using solution method could increase fluidization time from 12 to 80 minutes, and improve the metallization ratio from 22% to 81%. Reason was that coating MgO could effectively insulate the contact of metallic iron on particles, which provided the reaction time for carbon deposition and the production of Fe3C with low stickiness. Therefore, the decrease of metallic iron on particle surface led to the decrease of particle stickiness in fluidized bed reduction


IT'S A SCENE typical of an industrial chemistry lab. Roughly 50 people dressed in white lab coats are concentrating on experimental procedures: setting up titrations, checking pH meters, analyzing spectra. They may look like experts, but these experimenters don't have a degree in chemistry. They're eighth-grade students from Robert Treat Academy, an inner-city charter school in Newark, N.J., and they're getting real-world lab experience, thanks to Students 2 Science. Students 2 Science is a new nonprofit corporation in East Hanover, N.J., that is providing laboratory experiences to middle school and high school students, with a particular emphasis on minority, underrepresented, inner-city, and female students. Students work alongside professional chemists who are volunteering to serve as mentors. "As scientists, we love sharing our work," says Paul A.

Utility analysis is a technique which allows for the estimation of the financial impact of human resource (HR) interventions. While utility analysis methods have been available for decades, their application is still not widespread. Some argue that this is because managers do not understand the techniques and suggest that allowing managers to participate in the analysis would increase understanding and, as a results, use and acceptance of utility analysis. The current work posits that translating the value of HR interventions into financial terms may not be necessary. It may be more useful to determine the direct impact of HR programs on employee behaviors and attitudes. The impact of these changes on the bottom line may then be determined. Building upon the recently proposed multi-attribute utility analysis and the strategic perspective offered by the Balanced Scorecard, this paper presents a strategic utility analysis method. Strategic utility analysis requires that multiple outcomes, not only financial, be considered in order to determine the utility of a given HR intervention. It further stipulates that these outcomes should come directly from the company's business strategy. The strategy should imply certain organizational capabilities and strategic utility analysis should measure the contribution of HR interventions towards building these specific capabilities.

Students' successful comprehension and achievements in teachers' instruction mainly lies in the latter' s clear awareness and pursuit of teaching essence, innovation and teachers' professional development.


Plasmacytoma a neoplastic proliferation of plasma cells is one of the forms of plasma cell dyscrasia that may manifest as multiple myeloma, primary amyloidosis, or monoclonal gammopathy of unknown significance. Factors such as viral pathogenesis and irritation from inhaled irritants have been noted. Genetic factors may also play a role; however, no specific loci for the origin of this disease have been identified. Plasmacytoma mainly affects people in the 5th to 6th decade of their lives. Diagnostic criteria for SP (published by the International Myeloma Working Group, IMWG) indicate that the lesion must be solitary in nature without clinical, radiographical or biochemical evidence of systemic MM. Recent guidelines recommend MRI or PET/CT evaluation, in addition to standard x-ray skeletal survey, to exclude multifocal disease [1].


In 1942 the author published the so-called tetrazolium method for determination of the germinability of seeds (3). This method is based upon the reduction in germinability of the seeds due to a gradual dying-off of the embryo (2). The topographical spread of necrosis of embryo tissues can be demonstrated by means of 2,3,5-triphenyl-tetrazolium-chloride. This compound is colorless but is reduced (hydrated) into the stable but nondiffusible red formazan by living cells (3). Coloration of a cell by tetrazolium is a definite indication of its viability because necrotic cells remain uncolored. By means of extensive experiments conducted over a period of years, the procedure has been perfected to demonstrate which parts of the embryo are at least sufficiently viable to make germination possible (4). The recent publication of R. H. Porter, Mary Durrell, and H. J. Romm (1) concerning the topographical tetrazolium method does not, however, present the method correctly in relation to several essential points. In order to correct these errors, the present author submits a short description of his method (3). Use of the tetrazolium method merely involves preparation of the embryo of various species of seeds in such a way that all those parts which are decisive in the estimation of germinability be made visible. In most cereals the anterior face of the embryo must be visible. Since the pericarp is impermeable and opaque in most cereals, the embryo must be removed from the kernel with a lance-like scalpel or dissecting needle. Except in maize, a longitudinal section through the center of the embryo is not adequate because the lateral root primordia remain invisible. Only in oats is the pericarp sufficiently transparent to obviate excision of the embryo. The embryo of maize, however, possesses a simple root primordium, and the lateral root primordia (secondary radicles) in the mesocotyl are uniformly distributed. In this instance a longitudinal section provides the best preparation (5). The presoaking of the seeds in water is necessary only to facilitate the removal of the embryo. Initiation of germination is neither necessary nor significant for the test because even non-after-ripened cereals can reduce tetrazolium According to the method described below, the cross-sectioned grains of oats are placed in tetrazolium solution without pre-soaking. Only in the case of maize is the staining of the scutellum important in relation to germinability. This response of


This paper presents a method for estimating the potential for liquid droplet erosion in compression system components, such as the impeller of centrifugal compressors. The erosion model selected is used to calculate a threshold velocity that represents the limit for the onset of erosion damage. The parameters used in the model include the liquid phase density and viscosity, impeller geometry, shaft rotational speed, impeller material hardness, maximum droplet diameter size, and sonic velocity of the liquid phase. The potential for erosion is assessed by comparing the threshold velocity with the maximum expected impact velocity. The model was benchmarked against several industry standards and the original equipment manufacturer's (OEM) own expertise regarding blade protection from liquid erosion in steam turbines. The results from the proposed erosion potential method agreed closely with the steam turbine experience.

All the patients were followed up from 6 months to 18 moths, in whom 7 have had normal urination and 1 needed intermittent dilation. [Conclusions] Endoscopic operation with plas makinetic energy were believed to be the first choice of treatment for traumatic posterior urethral stricture and occlusion.


From 31 January to 1 February 1953, a North Sea storm surge devastated coastal areas of the United Kingdom, Belgium, and the Netherlands. Apart from enormous economic damage and severe societal disruption, over 2,000 people died across the three countries. This paper discusses the available data on loss of life in these three countries and examines the application of these data for loss of life estimations and general flood management practices.

The title reaction of trans-3-acetoxy-4-(4-methyl-3-trimethylsiloxy-3-pentenyl)cyclohexene proceeds in the presence of Et2AlOAr, where Ar=2,6-di-t-butyl-4-methylphenyl, affording stereospecifically the cis isomer of 2,2-dimethylbicyclo[4.4.0]dec-9-en-3-one. In contrast, the cis-disubstituted cyclohexene compound reacts only sluggishly to produce a mixture of the cis- and trans-fused octalones. Similar stereospecific effect of the allylic double bond configuration on the ease of cyclization has been observed in the synthesis of karahanaenone from 3,7-dimethyl-6-trimethylsiloxy-2,6-octadienyl acetate and related reactions.


This Bachelor thesis aims to apply an intersectional perspective on immigrant health in Germany. The social construction theory by Schneider and Ingram is applied to reveal that German migration policies construct different populations, leading to different forms of discrimination and exclusion from health care services.
The literature review shows that the interaction of migration and health is deeply gendered, for women are exposed to specific health risks and vulnerabilities, often arising from stereotypical gender roles and bad living conditions in respective accommodations. In the public discourse around immigrant women are mostly perceived only in their role as mothers and caregivers, while their contribution to health care and their own health needs is neglected. The analysis refers to Bremen as a positive example for access to health care for immigrants in Germany with the "Bremer model" being exemplary for other German federal states.
The Intersectionality Based Policy Analysis finally highlights that the constructed target groups are not homogeneous, but that their various needs, stories, vulnerabilities and potentials have to be incorporated into policy making to work towards health equity in Germany.

psychological drama, especially emphasizing the sexuality of the characters (older as well as younger) and unease about same. Hamlet is made believable as an emo guy in a tough spot, and the reactions to his increasingly bizarre behavior are credibly fleshed out; overall, there's an effective, foreboding sense that the rot in Denmark has spread from its original source and that just about everybody is infected with their own doom. Gratz' Something Rotten: A Horatio Wilkes Mystery (BCCB 11/07) is more successful as a standalone, Hamlet-based, genuinely enjoyable YA read, but this exploration could be a helpful companion to a reading of the original text or an interesting partner with a viewing of a film version.

Cold spraying technology is an advanced spraying technology developed based on the principles of aerodynamics. It is mainly used to deposit and repair the surface of metal alloy parts to ensure that the parts have better mechanical properties and service life. Compared with traditional thermal spraying technology, cold spraying technology has many advantages, such as low spraying temperature, low oxygen content and low porosity, and it is not easy to cause oxidation, burning, phase change and other phenomena during spraying. This article reviews the principles, technical parameters, and characteristics of cold spray technology, focusing on the effects of powder particle size and shape, particle and substrate temperature, critical speed, spray gun, collision angle, and spray distance on coating quality and deposition efficiency. In addition, the current research and application status of cold spray technology in the preparation of anti-corrosion coatings, high temperature resistant coatings, high temperature oxidation and wear resistant coatings are discussed, and the development prospects of cold spray technology are prospected.


This paper presents a heuristic approach to derive the Laplace-Stieltjes transform (LST) and the probability generating function (PGF) of the waiting time distributions of a continuous- and a discrete-time GI/G/1 queue, respectively. This is a new idea to derive the well-known results, the waiting time distribution of GI/G/1 queue, in a different way.


Abstract The synthesis of 3,5-dioxoheptanedioic acid derivatives based on the reaction of ketene with malonyl chloride was developed. Resulting diketones were subjected to Ru–(S)-BINAP-catalyzed asymmetric hydrogenation. The products were transformed into enantiomerically pure 3,5-substituted-δ-valerolactones.

Written constitutions tend to be codified when power relations are substantially changed in a political system. Frank Vibert considers whether the UK is experiencing such a moment and debates the practical and philosophical benefits and drawbacks to putting the constitutional pen to paper.


This paper proposes a model of technical change based on Adam Smith's analysis of the role of division of labor in economic growth. Technical change is the discovery of new capital goods which help workers or even replace workers performing precise tasks. As a consequence, the number of opportunities of innovation is an increasing function of the number of tasks performed in the economy. We first model division of labor within firms and then model the research sector. The probability of innovation is not only a function of the quantity of resources allocated to the research sector, but also of the total number of tasks. We show that this theory yields a growth model without scale effects. The market equilibrium yields an optimal equilibrium growth rate, but a sub-optimal transitory dynamic. This sub-optimality can take two forms : either too many researchers and an internal division of labor too small an internal division of labor, or too few researchers and an too high an internal division of labor. We show that the long run growth rate depends on the assumption made on the evolution of the number of tasks during economic development. If the number of tasks increases in the long run, a positive effect of the diversity of capital goods on productivity is not necessary to obtain a positive per capita growth rate.

A novel IC-like integration device structure and manufacture process for a thyristor-based capacitor discharging circuit applicable to pulse current generation are studied in this paper. Two structures are compared by means of different design of diode which used as for trigger main thyristor. Substitution of a Zener diode with a p+ n avalanche diode in the equivalent circuit can give more stability of pulse-voltage temperature property. Simulation results by Silvaco commercial simulation software indicate that a shallow junction of the avalanche diode has a much improvement in the manufacture process as well as the stable operation at elevated temperature


Objectives: The global problem among chronic patients was Medication adherence. Current study was describing the frequency of medication adherence among the patients who had hypertension and diabetes mellitus. Methods: The cross sectional study was conducted in different hospitals of Hyderabad, Pakistan. A total of 500 patients were recruited by cluster sampling method. The duration of study was 01 year after the approval. The data were assessing based on morisky scale. Results: The response rate was 85.4%. The mean age of the patients was 63 years + 6. Majority of patients were male i.e. 62.99%. The duration of hypertension and Diabetes Mellitus were almost 8years + 3. Averagely 05 drugs were prescribed for treatment. Based on morisky scale, more than 50% of the patients were categorized in low adherence and only up to 20% patients were in high adherent class. Conclusion: The results clearly revealed that due to chronic diseases, the rate of adherence was too low. For overcome this vulnerable condition, proper counselling will be provided to the patients and the best counselor is Pharmacist that helps to increase the rate of adherence with medications.

Optical buffer is an important component in optical switching and optical signal processing. In this paper, we present a novel all-optical buffer based on nonlinear polarization rotation induced by injection current of semiconductor optical amplifier. With Mueller matrix, we theoretically investigate the change of polarization state induced by nonlinear polarization rotation in semiconductor optical amplifier. The operation of the proposed optical buffer at 2.5Gb/s is experimentally setup. The loading and reading operations with 1024bit with this optical buffer are demonstrated. Polarization maintenance is taken into account to give the optimum operation condition


The aim of the study was to analyze the possibility of using selected rainfall-runoff models to determine the design hydrograph and the related peak flow in a mountainous catchment. The basis for the study was the observed series of hydrometeorological data for the Grajcarek catchment area (Poland) for the years 1981–2014. The analysis was carried out in the following stages: verification of hydrometeorological data; determination of the design rainfall; and determination of runoff hydrographs with the following rainfall-runoff models: Snyder, NRCS-UH, and EBA4SUB. The conducted research allowed the conclusion that the EBA4SUB model may be an alternative to other models in determining the design hydrograph in ungauged mountainous catchments. This is evidenced by the lower values of relative errors in the estimation of peak flows with an assumed frequency for the EBA4SUB model, as compared to Snyder and NRCS-UH.


High concentration arsenic consumption through drinking water and food is a major public health problem in Bangladesh (Tondel et al., 1999; Misbahuddin, 2003). At present more than 25,000 are suffering from arsenicinduced skin manifestations and it is predicted that 0.20.3 million people will die due to arsenic-induced cancer (Meharg and Rahman, 2003). Recent report shows that people consuming arsenic without skin manifestation may shows systemic manifestation (Majumdar et al., 2009).


A IDS is characterised by progressive lymphopenia predominantly of the T helper/inducer cells which renders the patient immunologically compromised and thus susceptible to a variety of opportunistic infections and malignancies. A prime determinant of susceptibility to HIV infection is the presence of the CD4 molecule on the cell surface which acts as a receptor for the virus and which binds the gpllO envelope glycoprotein of the virus. While infection and depletion of CD4+ T cells is likely the major contributor to quantitative viral replication and pathogenesis of immunodeficiency in the host, infection of other cell types has been demonstrated. These include monocytes' and B cells.P The first abnormality to be associated with AIDS was the reversal of the normal T helper to T suppressor (T41T8) ratio found in the blood.:' It is known that the inverted ratios are due to a marked decrease in absolute numbers of helper/inducer T cells combined with a variable number (increased, decreased or normal) of suppressor/cytotoxic T cells." T4+ cells can be subdivided into inducers of help and inducers of suppression, and both populations seem to be equally depleted in early HIV infection. The T4+ cell plays a central role in orchestrating and controlling many of the immune responses. The depletion of T4+ cells caused by the tropism of the HIV for this cell type is consistent with results of in vitro tests for T cell function. Isolated T helper cell function has been reported to be normal or depressed, depending on severity of T cell depletion, in such assays as pokeweed driven immunoglobulin production. Both the proliferative responses to soluble antigen and the autologous mixed lymphocyte response are more consistently depressed or even abrogated, and these may be the earliest qualitative defects in the immune system of the HIV infected patient. Antigen specific proliferative responses are an in vitro correlate of Delayed Type Hypersensitivity (DTH) , and skin testing shows impairment in infected patients. Total anergy occurs in those with severest T cell depletion. 6 T8 cells which comprise of the T suppressor and T cytotoxic subsets can be normal, elevated or decreased. In full-blown, end-stage disease, severe T4 cell depletion is probably associated with panlymphopenia including the T8 subpopulation. In asymptomatic HIV infected individuals, there is often an increase in T8 numbers. This elevation is due to a subset of T8 cells associated with cytotoxic precursor and effector function." Those patients infected mount poor cytotoxic effector responses in vitro but presumably have relatively normal precursors. The specificity and function of the increased T8 cells identified as cytotoxic cells and their relevance to the clinical course or prognosis remains to be determined. There is no evidence of excessive suppressor activity in AIDS patients? but several workers have described suppressor factors in the serum." Pahwa? has suggested that retrovirus products such as the gpllO envelope glycoproteins themselves could be immunosuppressive. NK cell activity is normal in asymptomatic infected individuals but declines with severe immunodeficiency. Another two characteristic findings in AIDS patients are elevated levels of immune complexes and hypergammaglobulinaemia.l" Despite this polyclonal immunoglobulin elevation, AIDS

Semantic annotation of images is an important step to support semantic information extraction and retrieval. However, since the behaviors of annotators could influence the performance of a retrieval system, the modeling of annotators must be considered during the annotation especially in multiple-annotator system. This paper devised an annotator model from three different aspects, expertise, trustworthiness, and diligence. And also conducted experiments to evaluate the annotator model; the experiments showed the proposed annotator model improved the annotation and retrieval significantly.


Abstract A high‐affinity iron assimilation system mediated by siderophores may be required for efficient nitrogen fixation in the genus Rhizobium, in view of the role of iron enzymes in this process. Siderophores biosynthesized by three strains of Rhizobium leguminosarum bv phaseoli were purified, hydrolyzed and analyzed. Using paper chromatography, two well‐defined spots that, according to their relative mobility, were identified as the L‐amino acids: threonine and tyrosine. Using thin layer chromatography, 2,3‐dihydroxybenzoic acid (2,3‐DHBA) was identified in the hydrolyzed samples as well. The spectrophotometric profiles from 2,3‐DHBA itself and a purified siderophore preparation from one of the strains were similar. The FAB+ mass spectrum showed a maximum peak of 637 m/z that indicates the purified compound has a molecular mass of 636 Da. Analysis of our results indicate that the compound that matched that molecular mass may contain: 2,3‐DHBA, tyrosine and threonine in a proportion of 1:1:3, with two of the threonine bound by their methyl group. A 30 KDa cell membrane protein was identified in cells grown under iron‐starved conditions. The siderophore and membrane receptor protein, structural constituents of the high‐affinity iron transport system in this species were found different to the compounds previously described in this genus by other authors.

Heart rate variability(HRV ) is currently regarded as an importantindependent sensitive prognostic index for sudden cardiac death,especially,for suddendeath after acute myocardiac infarction,There is little study so far in establishing stan-dard physiological values of HRV in China.In this paper,standard diviation(SD) of R-Rintervals and HRV index methods were applied for measuring the value of HRV in 120hialthy subjects aged 40-70 years. The varibale ranges (95% confidence limits)of 24 hourSD and HRVindex are 118.15+ 15.37ms HRV index 18.62 2.31.The study showedthat HRV in elderly group (n = 54 )was significantly(P 0.05) lower than that in middleaged (n =66) :HRVduring nightime(9pm to 9Am) was higher(p0.0l) than that dur-ing daytime(9Am to 9pm),In particular,HRV from 6Am to 9Am was lowest in wholeday,This time period fallies with the highest incidence hours of the heart event, In pre-sent study,the HRV fluctuating character and its implication were studied and dis-cussed .


Cancer causes many deaths in the world. One of the most dangerous types of cancer is skin cancer caused by cancer cells that grow and spread uncontrollably in the skin layers. There are an estimated that 100,000 new cases of skin cancer will occur in the United States, which will cause around 6000 deaths by 2020. The survival rate of people with skin cancer can increase if successfully treated at an early stage. Examination of the lesion or dermoscopy images takes a long time and is prone to errors due to differences of opinion by doctors. A computer program for image processing was developed to improve accuracy and efficiency that helps doctors diagnose and evaluate. The most crucial stage in the diagnosis process is the segmentation of skin lesions. Wrong segmentation results will affect accuracy at the classification stage. This study developed a segmentation model for a skin cancer image that uses the MobileNet model as an encoder block and Linknet model for a decoder block by selecting the best hyper-parameter value from several training scenarios. MobileNet encoder and Linknet as a decoder are known to have the same ability, which is to overcome the problem of computational efficiency without compromising accuracy. Four hyper-parameters used are learning rate, the number of epochs, image size, and using pre-trained or not. Besides, there is a performance comparison scenario between the MobileNetV1 and MobileNetV2 encoder blocks. The model trained using the 2017 ISIC Challenge dataset consisting of 2000 training data, 150 validation data, and 600 test data. The Intersection over Union score obtained was 71.5% from models trained with a hyper-parameter learning rate of 0.001, 50 epochs, with an image size of 256 × 256 × 3, using a pre-trained model, and using a MobileNetV1 encoder block. The mask image that is the result of the segmentation of skin cancer images using the MobileNet encoder model and Linknet decoder is accurate enough to be used in the process at a later stage.

On the path towards developing passive transducers for wireless sensing in high temperature (>560°C) environments, we experimentally demonstrate the design, manufacturing and wireless interrogation of resonators patterned on GeO2 substrates, leading to an initial estimate of the coefficients of temperature with frequency of surface acoustic waves propagated on this substrate.


Casimiro Castro, master of nineteenth-century Mexican lithography, was the first Mexican artist to conduct his creative work from the heights of a hot air balloon. The result was an unprecedented vision of the capital. His work offers a reference point on the city's evolution, even when his work was being republished. The aerial perspective, besides offering romantic tinges, attests to public amusements and diversion and urban regulations of those times.


We report a case of primary laryngeal tuberculosis in a 54 year old Indian male, who had hoarseness as his presenting complaint. This case highlights that laryngeal tuberculosis may occur even without pulmonary tuberculosis, and the characteristics of the lesions now appear to be more nonspecific than earlier. Otolaryngologists and airway physicians need to be more alert to the emergence of laryngeal tuberculosis with atypical clinical manifestations and consider it in their differential diagnosis of all laryngeal diseases.

Key Clinical PointsUrinary Tract Infections in Older Men The prevalence of bacteriuria and the incidence of urinary tract infection are substantially higher among older men than among younger men. The majority of older men with urinary tract infection have underlying urologic abnormalities. Effective treatment of infection requires determining whether the site of infection is the kidney, bladder, or prostate. Effective management of symptomatic episodes requires selection of antimicrobial therapy on the basis of urine culture. Chronic bacterial prostatitis requires prolonged antimicrobial therapy (30 days). Men with recurrent episodes who do not have urologic abnormalities that can be corrected or identified may require long-term suppressive therapy with antimicrobial agents.


Ways of extracting financial condition indices (FCI) are explored and alternative FCIs external to the Chinese economy are constructed to model their predictive content. The exploration aims at highlighting the rich and varied dynamic features of financial variables underlying FCIs and the importance of synchronising dynamic information between FCIs and the real-sector variables to be forecasted. The modelling experiment aims at improving the forecasting model upon which the FCIs are assessed. Four variables are chosen as the likely macro channel of the FCIs affecting the Chinese economy. It is found that the FCI-led models enjoy forecasting advantages over a benchmark model in three out of the four variables, although the benchmark model is not dominated by the FCI-led models when judged by in-sample encompassing tests. The evidence indicates the increasing exposure of the Chinese economy to the global financial conditions.

Considerable dispute exists with regard to the classification of hair follicle mites,belonging to the family Demodicidae in the last twenty to thirty years, due to indis-tinct morphological characteristics. In the present investigation, we carried out further detailed studies on the classi-fication of the family Demodicidae and made a comparative study on the speciesDemodex folliculorum. the human hair follicle mite.The taxonomic characteristics of the family Demodicidae are chiefly: 1. number,position and shape of palpal claws (setae), 2. shape and distance between two supracoxal spines, 3. shape of pharyngeal bulb, 4. shape and position of aedeagus, 5. posi-tion and with or without lid of genital orifice, 6. shape of posterior portion of opis-thosoma, 7. presence or absence and shape of proctodaeum.A table of comparative measurements in micron of length and width of gnatho-soma, podosoma, opisthosoma, and total length of and among three human speciesand subspecies of hair follicle mites, was made for differentiation. A list of 15 speciesand subspecies of hair follicle mites was given, including their species names, Chinesenames and hosts. We found that the common human hair follicle mite in China is dif-ferent from those in other countries. We, therefore, propose to erect anew subspecies.Demodex folliculorum sinensis, subsp. nov.The differential characteristics of the new and the nominate subspecies of Demodex folli-culorum are given in the following table for comparison.f.folliculorum the nominate subspecies f. sinensis the new subspecies302.07μ296.99μgenital orifice situated in between 2nd pair of dorsal podosomal setae tween 1st and 2nd pairs of dorsal podosomal setaeHolotype allotype and paratypes 20 20 were collected off man inShanghai; deposited in the Department of Parasitology, Shanghai First Medical College, Shanghai.

Copper is a valuable material in renewable energy technologies, such as catalysts on gas diffusion electrodes in electrochemical devices for the electrochemical reduction of carbon dioxide (CO2) to high-value products. By understanding the kinetics of ion-transfer in copper corrosion and deposition processes, we can gain a better understanding of the durability of devices that employ copper. Measurement of ion-transfer kinetics of bulk metal materials has a magnitude of challenges, increasing the difficulty of precisely analyzing the fundamentals of the processes. To assuage these concerns and obtain a more representative microscopic picture of Cu corrosion processes while investigating the effect of the anions on copper durability, we created several model microenvironments that employ copper underpotential deposition (UPD) on a well-ordered Au[111] surface: 1) a model system in sulfuric acid; 2) a bridging environment (methanesulfonic acid), and 3) a model microenvironment for gas diffusion (Nafion electrolyte). After analyzing these three systems, we expanded our models to investigate the effects of steric by adding ethanesulfonic acid and the effects of electronegativity by adding triflic acid. Our results demonstrate the effect of supporting anions on the ion-transfer kinetics of Cu UPD corrosion and deposition processes to give a better understanding of fundamental kinetics and mechanisms in gas diffusion environments.

Objective:To discuss the diagnosis and clinic value of MRI in tuberculosis of spine.Methods:51 cases of patients who had been diagnosed or suspected as tuberculosis of spine by X-ray plain film were carried out MRI routine T2WI,T1WI and STIR scan,some cases were carried out enhanced scan,finally compared with pathological results.Results:43 cases of patients were diagnosed as tuberculosis of spine (84.3%). All cases with MRI were corrrectly diagnosed (100%). Pathological T1WI was shown as low signal,some shown as as mixed signal. T2WI was shown as uneven high signal,the abscess focus was shown T1WI low signal,T2WI high signal.Conclusion:MRI can correctly show the size of focus and the extent is invaded,specially cold abscess beside vertebra is obviously superior to CT and X-ray. So we think the correct diagnosis by MRI on tuberculosis of spine is so high,and can detect it in the early stage. MRI should be the routine examination of tuberculosis of spine.


This study was aimed to analyze color characteristics of silk fabrics dyed with a variety of commercial natural dyes focusing on hue/tone system. Using eleven different natural dyes, single and sequential dyeing were performed under a variety of conditions of dye bath concentration, mordanting, and dyeing sequences. Color characteristics of dyed silk fabrics were investigated by Munsell`s color notation of H V/C and PCCS (Practical Color Coordination System) tones. As results, most of yellowish natural dyes as principal shades in natural dyeing showed Y or YR for hue families while d, ltg, and g for tone, which agrees with colors frequently used in comtemporary apparel industries. As for single dyeing, some hues like R, RP, G, GY, and BG were found to have their own tones owing to the used natural dyes. For varying hues in natural dyeing, sequential dyeing is useful in that GY, G, and BG rarely appeared in single dyeing were frequently shown in sequential dyeing by combination of some dyes. In the other hands, mordanting may be employed for tone variation in that aluminum seemed to contribute to light and dull tones, copper to dull, and ferrum to garyish and dark ones. These results can be helpful to design colors for fashion fields by natural dyeing.


In the last few years, an increasing number of texts published in environmental journals and in art magazines have addressed the "ghostnet" issue and referenced how artists in Northern Australia use discarded or abandoned nets to create art and craft items. By analysing the artistic life of the ghost nets, from the creative process to trade networks, this article provides a new perspective on marine pollution and highlights Australian Indigenous peoples' agency toward this environmental and global issue. It presents ghostnet art as a transgenerational and transcultural practice that reflects the articulation of Indigenous and Western knowledges, two systems of thought and action that are united to solve ecological, economic and cultural issues.


In today's fast-paced microcomputer world, getting a high-quality product to market in a timely fashion can make the difference between long-term success and mere survival for a company.

This article explains how the Monetary Control Act (MCA) of 1980 paved the way for the transition away from paper to electronic check clearing and processing, ultimately leading to the successful implementation of the Check Clearing for the 21st Century Act (Check 21) in 2003.


Because consumer discrimination can reduce productivity, it is often impossible to tell whether differential productivity is the effect of discrimination or of differential ability. Detailed data for the sports labor market make it possible to separate consumer discrimination from ability. We use a unique approach to determine whether the entertainment value of baseball players is related to their race: we examine whether race directly affects the value of a player in the market for baseball cards. In contrast to studies that use salaries, there is no room for owner or coworker discrimination. Our evidence supports the hypothesis of consumer discrimination.


Landscape poetry in the Southern Dynasty(Song,Qi,Liang and Chen) had great significance in the Chinese landscape literary history.On the one hand,new areas of landscape poems creation has been opened upandlaid the literary status of landscape poems in the Southern Dynasty.On the other hand,through unremitting efforts of several generations of poets,the basic form of landscape poetry structural model with landscape-based,five-character quatrains was established in the Southern Dynasty.Therefore,an elegant and beautiful artistic feature wasformed and had a profound impacttothe later landscape poetry.


With the popular trend of higher education and the reform in higher education, the subjects of ideological and political education and the related working patterns change a lot. Therefore, ideological and political educators should put "two disciplinary" into full use in strengthening the theory construction of ideological and political education, relate the ideological and political quality with comprehensive qualities, and strengthen the work of educating students and the construction of culture and network, etc.


We propose a notion of interval object in a category with finite products, providing a universal property for closed and bounded real line segments. The universal property gives rise to an analogue of primitive recursion for defining computable functions on the interval. We use this to define basic arithmetic operations and to verify equations between them. We test the notion in categories of interest. In the category of sets, any closed and bounded interval of real numbers is an interval object. In the category of topological spaces, the interval objects are closed and bounded intervals with the Euclidean topology. We also prove that an interval object exists in and elementary topos with natural numbers object.


Long before Mary Shelley created her Gothic masterpiece, Frankenstein, she told other tales - spine-tingling fireside tales of lost loves and drowned sailors. She also shared true stories of a girl endlessly drawn to her mother's grave, and of a girl whose father had forgotten all he once held dear. Sharon Darrow has skilfully spun fiction from fact to recreate the details of a particularly critical time in Mary Wolllstonecraft Shelley's life - when she was fourteen and sent away to live with another family, the Baxters. Masterfully matched by Angela Barrett's exquisite, atmospheric illustrations, this is a rich tapestry of stories within stories - those told, those written and more extraordinary, those lived.


Objectives: We sought to assess with magnetic resonance imaging (MRI) the influence of strain type and gender on left ventricular (LV) global function and mass in 3 inbred mouse strains with a normal cardiac phenotype. Materials and Methods: A total of 30 mice from 3 inbred strains (C57BL/6, 29S2/SvPasCrl, and C3HFeJ) were studied on a 7.05-T MR scanner using ECG-triggered cine sequences. LV mass and volumes were calculated with inclusion and exclusion of papillary muscles (PMs) in the LV wall. Results: Significant differences were found with strain and gender (P < 0.001), with strain–effect but no gender–effect for ejection fraction (EF), end-diastolic volume (EDV), and end-systolic volume (ESV). There were no differences in LV mass between strains but lower values in female mice except in the C3H strain. The exclusion of PMs led to the relative underestimation of EF (−6.1%) and of LV mass (−6.4 mg) and the relative overestimation of EDV (6.3 &mgr;L) and ESV (5.3 &mgr;L). Inter- and intraobserver reproducibility was better when PMs were included. Conclusion: The use of MRI demonstrates cardiac interstrain and gender-related phenotypic diversities that are essential factors to consider when building genomic databases and designing studies.

Gender issue have given birth to different roles, function, responsibilities and rights, as well as activities of men and woman in social society. This mistake have implications for discriminatory attitudes in treating access, participation and social control. In the view of Islam it has never been a matter of gender, because it's already explained in the Quran. Islam have provided justice between men and woman proportionally, women have a comprehensive and aqual role as men as servants of Allah and carry out the mandate. It's needs a solution to reduce the existence of gender disparities in society. This paper will discuss about Asghar Ali Engineer's view of gender. This paper is analyzed by looking for a variety of related literature. The result is that the Engineer offer two methods, contextual normative and transcedental. Namely reinterpreting the text of the Quran abaout gender which is the contextualized with the local socio-culture, because the law has a flexibel nature to follow the changing times.


The experiments reported in this thesis investigate whether the current understanding of crossmodal spatial attention can be applied to rear space, and how sound parameters can modulate crossmodal spatial cuing effects. It is generally accepted that the presentation of a brief auditory cue can exogenously orient spatial attention to the cued region of space so that reaction times (RTs) to visual targets presented there are faster than those presented elsewhere. Unlike the conventional belief in such crossmodal spatial cuing effects, RTs to visual targets were equally facilitated from the presentation of an auditory cue in the front or in the rear, as long as the stimuli were presented ipsilaterally. Moreover, when an auditory cue and a visual target were presented from one of two lateral positions on each side in front, the spatial co-location of the two stimuli did not always lead to the fastest target RTs. Although contrasting with the traditional view on the importance of cue-target spatial co-location in exogenous crossmodal cuing effects, such findings are consistent with the evidence concerning multisensory integration in the superior colliculus (SC). Further investigation revealed that the presentation of an auditory cue with an exponential intensity change might be able to exogenously orient crossmodal spatial attention narrowly to the cued region of space. Taken together, the findings reported in this thesis suggest that not only the location but also sound parameters (e.g., intensity change) of auditory cues can modulate the crossmodal exogenous orienting of spatial attention.


P700 Chi-protein was isolated from a marine green alga Bryopsis corticulans with SDS-resolved thylakoid membranes by SDS-PAGE. After elution from the gel, the recovered protein revealed a 100 KD polypeptide by re-electrophoresis . The same SDS-PAGE procedure was used to isolate P700 Chl-proteins from spinach (Spinacea okracea ) and another marine green alga Codium fragile . Polyclonal antibodies to Bryopsis P700 protein were raised in rabbits. The antibodies were shown to cross-react with P700 Chl-protein and Chl-protein complexes containing P700 protein from B . Corticulans, C. f ragile, and even spinach. Results indicate similarity of the amino acid sequences of the P700 Chl-proteins and the highly conserved structure of the apoproteins of phylogenetically distant species over evolution. The antibodies cross-react with none of the components of PSUU in the species tested , indicating an independent pathway of evolution of photosystem I and photosystem II of later origin.


Introduction: Thyroid disorders in pregnancy are among the common endocrine disorders. During pregnancy several physiological changes occur in maternal thyroid function and failure to adapt to these changes result in thyroid dysfunction. Thyroid dysfunctions have many adverse effects on mother and fetus, like miscarriages, preeclampsia, eclampsia, placental abruption, preterm delivery, low birth weight, post partum haemorrhage, neonatal hypothyroidism and impaired neurological and intellectual development of fetus. Study aimed to find out the prevalence of thyroid dysfunction in pregnancy and to know maternal and foetal outcome. Material and methods: This cross sectional clinical study was carried out at Obstetrics and Gynecology department in collaboration with Biochemistry Department, IGIMS, Patna, Bihar from August 2018 to August 2019 including 100 pregnant women with single intrauterine pregnancy in first trimester between 6-14th weeks of gestation. TSH level was estimated in all the pregnant women along with FT3, FT4, and Anti TPO Ab. According to the thyroid profile, patients were divided into 4 groupsNormal/ Subclinical/ Overt hypothyroidism and hyperthyroidism and followed till delivery for maternal and perinatal outcome. Results: In our study of 100 patients, 87 were found to have normal thyroid function and 13 cases were having subclinical hypothyroidism, using a cut off TSH level of 2.5-10uIU/ml in AntiTPO Ab positive and 4-10uIU/ml in AntiTPO Ab negative cases. No case of hyperthyroidism or overt hypothyroidism was found. These 100 patients were divided into two groups. Patients having normal thyroid function were included in Group 1 and patients with subclinical hypothyroidism were included in group 2. In subclinical hypothyroidism group 5(38.46%) cases were AntiTPO Ab positive and 8 cases were AntiTPO Ab negative. Conclusion: Our study concludes that there is high prevalence of subclinical hypothyroidism (13%) in pregnant women during 1st trimester. No significant difference was seen in maternal and foetal outcome between euthyroid patients and treated subclinical hypothyroid patients.


The present study was an attempt to examine systematically the productions of autistic and normal children at the same developmental level in their drawing ability, to confirm or disprove the clinical observations of fragmentation and overlap


Pharmacists as members of health care teams, have a central role to play with respect to medication. The pharmaceutical care and cognitive services which pharmacists are able to provide can help prevent, ameliorate or correct medication-related problems. There are however many barriers to the provision of these services and one of the barriers commonly cited by pharmacists is the lack of remuneration for their expert services. The aim of this study is to ascertain if patients in South Africa are willing to pay for pharmacistprovided services which may reduce medication related problems, and thereby determine the perceived value of the pharmacist-provided services, by patients. The study will also seek to determine factors that influence willingness to pay (WTP), including financial status, gender, race, age and level of education. In addition the perceived value of the pharmacist's role in patient care, by third party payers (SA Medical Aid providers) and their WTP for pharmacistprovided services (such as DSM) on behalf of patients through their monthly premiums will also be investigated. The study was conducted as a two-phase process: the first phase focused on the opinions of patients and the second phase on the medical aid companies. In phase-1 a convenience sample of 500 patients was recruited by fifty community pharmacies distributed throughout the nine South African provinces. Data collection, consisting of telephonic administration of the questionnaires, was conducted and the survey responses were captured on a Microsoft Excel® spreadsheet. All the captured information was analyzed using descriptive statistics, box and whisker plots, analysis of variance (ANOVA) and regression analysis. In phase-2, medical aid schemes that are registered with the Council of Medical Schemes (CMSs) of South Africa were included in this research. A fifteen point questionnaire was completed electronically via e-mail by willing medical aid participants. Data was analyzed using descriptive statistics only. Only 233 or 88.6%, of the 263 participating respondents, were willing to pay at least one rand towards pharmacist-provided services. On average respondents were willing to pay R126.76 as out-of-pocket expenses. Respondents' WTP increased as the risk associated with medicationrelated problems was reduced due to pharmaceutical care intervention. Patients' WTP for Pharmacist-Provide Services towards reducing risks of Medicine-Related Problems, in SA. Irvine Mushunje xiii Of the 263 respondents who took part in this research, fifty percent were willing to pay at least R100 for a risk reduction of 30%, R120 for a 60% reduction and approximately R150 for a greater than 90% risk reduction. It was also found that the respondents' willingness to pay was influenced by their age, earnings, racial grouping, employment status, medical aid status and their level of satisfaction with pharmacist-provided care services. Of the thirty-one open medical aid schemes only eight (25.8%) participated in the study. Findings indicate that all the participating medical aid respondents were unwilling to pay for pharmacist-provided care services, although they perceived pharmacists as very influential healthcare providers and as having a significant role to play in reducing medication-related problems. In conclusion it was found that majority of participants were willing to pay for pharmacistprovided services directed towards reducing risks associated with medication-related problems. Until pharmacists are able to prove pharmaceutical care's utility and cost-effectiveness to thirdparty payers, pharmacists must look to the patient for reimbursement.


A new pixel-based technique permits the reconstruction of three-dimensional structure from serial section images. Image-algebraic operations such as erosion, dilation, skeleton and pruning are defined in terms of hit-or-miss t ransforms and procedures are coded in Fortran. A sequence of image algebraic operations is designed to interpolate the middle layer configuration from two serial sections. A conditional skeleton operation plays a key role to outline the middle layer. The method was applied to reconstruct the threedimensional pore geometry of rocks.


This is a historical look at the significant changes that have occurred within healthcare in New Zealand during the 1990s. Occupational therapy as a profession has had to become more adaptable and articulate to survive these reforms. In 1999 the health sector moved back to its earlier local political origins but this hasn't meant a return to the past for occupational therapy. Finally primary healthcare is identified as a future direction for occupational therapy to consider as the profession has a vital role to play in this area.


The fraction of directly-bound carbonyls of surface-adsorbed poly(methyl methacrylate) (PMMA) was determined using transmission Fourier-transform infrared (FTIR) spectroscopy. The small size of the silica used allowed these measurements to be made directly in the transmission mode from dried casts deposited on KBr salt plates. Curve fitting of the carbonyl-stretching region allowed the estimation of both the relative amounts and also the relative ratio of the absorption coefficients for the free and bound carbonyls. The bound-carbonyl fractions were found to vary smoothly from 0.3 to 0.1 for adsorbed amounts from 0.5 to 1.8 mg of PMMA/m2. The bound fractions depended primarily on the adsorbed amount of polymer. Only very small, perhaps even negligible, direct effects of the solvent composition (toluene vs. benzene/acetonitrile) or molecular mass (32 to 420 kg/mol) were observed. © 2006 Wiley Periodicals, Inc.

This chapter examines the impact of the COVID-19 pandemic on existing learning spaces and emerging learning spaces. The authors address the need to restructure teacher education programs to prepare teachers for flexible teaching in various modalities. Throughout this book chapter, the authors anchor their positions using research-based literature, highlighting the need for new and emerging spaces to ensure the learner's diversity about content delivery, student experience, and the management of these learning spaces. Additionally, the authors provide a critical overview of the need to redesign learning spaces to accommodate learning as learning and knowledge assessments. The chapter concludes by providing readers with a framework anchored on the teacher enterprise domain designed to evaluate and examine new and emerging learning spaces within the context of teacher, structure, content, and learners.


Pain is one of the most common symptoms that a surgeon may encounter in their patients with palliative care needs. Pain no longer serves an adaptive, protective mechanism but one that is maladaptive and has no redeeming purpose except to add to the patient's suffering. Effective management requires the surgeon to consider the bio-psychosocial-spiritual impact of the underlying disease when assessing the patient's self-report of pain. This chapter is a primer and provides an overview of the most common factors that a surgeon may want to consider in providing primary pharmacopalliation of pain, including analgesic selection and adverse effect management.


Cutaneous endometriosis seems to be more common in women who have had a pelvic or abdominal operation and primary cutaneous endometriosis is very rare. In our hospital we experienced a 41-year-old woman who complained of the appearance at the umbilicus of a nodule and had not had operation. This nodule was responsible for recurrent pain and increasing in size and it was excised. Pathology findings revealed cutaneous endometriosis. So we present a case of primary cutaneous endometriosis with a brief review of literature.


Laser acceleration of helium ions from near-critical density targets is studied as an ion source for hadron therapy of oncological diseases. Helium ions are considered a promising candidate for therapy due to higher precision in dose deposition and possibly higher Relative Biological Effectiveness. The feasibility of using PW-class lasers to produce 250 MeV per nucleon helium ion beams that meet the hadron therapy requirements is discussed. The relative effectiveness of laser acceleration of He3 and He4 ions is studied.


In this paper we consider the problem of designing LDPC codes to be used in bit turbo-receivers, where an outer binary (turbo) decoder iterates with a bit-detector computing LLR of coded bits from the channel outputs. This receiver structure has been proposed for several scenarios, including systems for high order modulations, MIMO, ISI, and Multi User systems. It has been shown that the bit turbo-receiver provides performance close to the optimal receiver if the bit-detector EXIT chart "matches" that of the outer code. Motivated by the observation that most bit-detector EXIT charts exhibit an almost linear behavior we then introduce the "slope" of the EXIT chart as a new parameter for the LDPC design. A family of binary LDPC codes having the possibility of tuning not only the rate, but also the slope of their EXIT chart, as well as the decoder complexity, is then an ideal candidate for being considered in future advanced transmission systems where the bit turbo-receiver will replace the more common BICM receiver that does not consider possible iterations with the bit detector. In this paper we provide an efficient algorithm for the design of LDPC codes ensembles with excellent performances with those constraints and derive some conclusions. It is shown that with a given performance threshold the complexity of LDPC decoder actually decreases when increasing the target slope, confirming the already observed fact that bit turbo-receiver requires weaker outer codes.


In computer simulations different methods are used to calculate tangential wheel-rail forces in vehicle dynamics and in the analysis of traction systems. For the simulation of vehicle dynamics and drive dynamics interaction, the varying methods have to be combined into one method. Using the friction coefficient decreasing with increasing slip velocity between wheel and rail, decreasing part of creep-force function behind the adhesion limit as well as various adhesion conditions can be taken into account in the vehicle dynamics simulations. The proposed method of wheel-rail forces calculation was tested using an ADAMS/Rail model of a four axle locomotive. The curving simulations with a varying tractive force show the influence on the wheel-rail forces distribution. A simulation of the adhesion test demonstrates the applicability of the proposed method for investigations of drive dynamics and vehicle behaviour interaction.


The purpose of this diploma thesis is to analyse the subject of bibliotherapy, its possible meanings and how these can be converted into versions using new media, especially the internet. First, bibliotherapy is seen in context with other forms of therapy and with regard to how they interact. Then, the history of bibliotherapy is outlined. To find a meaningful set of definitions, a special model is used. This part is continued with an examination of possible content, forms, addressees and approached problems in bibliotherapy.
As a method of research, a review of current journals in the field of behavioural medicine and psychiatry as well as traditional literature in the field is undertaken. Then, the way in which users can find health sites of high quality on the internet is discussed with special reference to consumer protection, legal and ethical issues. Information from interviews with librarians and other key-players in the field are used to highlight the Austrian situation regarding bibliotherapy and public libraries. Finally, some current developments in the UK are discussed. The findings suggest that there are mainly two ways of seeing bibliotherapy today. One is concerned with therapy using the written word, which can also be literature or poetry and therefore, in which librarians can play an important role. The other is more concerned with self-help manuals and here usually cognitive behavioural therapists or physicians are clearly involved and models of co-operations with libraries are developing.


In this presentation, I will investigate the determinants of property tax collection in Mexico. The tax is paid by all owners of land and dwellings in Mexico for the right of holding their properties, and is collected and managed by municipal authorities at the local level. This type of tax has attractive economic features such as efficiency, progressiveness, and good capacity to finance local public goods. However, the amount of public funds that are raised through the collection of this tax are extremely low. This presentation will describe the main results of the study and show how Stata was used to perform the analysis.


Pregnant women have been recommended to take FA daily to prevent birth defects in the brain and spinal cord. We previously showed that folic acid (FA) exerts an anti‐angiogenic activity. As angiogenesis is important for endometrial reorganization and embryonic development, there should be some mechanisms to allow the pregnant mother and the foetus to escape from the FA‐induced anti‐angiogenesis. This study was designed to investigate the effect of female sex hormones on the FA‐induced anti‐angiogenic activity.


In this work we investigate methods to improve the efficiency and scalability of quantum algorithms for quantum chemistry applications. We propose a transformation of the electronic structure Hamiltonian in the second quantization framework into the particle-hole (p/h) picture, which offers a better starting point for the expansion of the trial wavefunction. The state of the molecular system at study is parametrized in a way to efficiently explore the sector of the molecular Fock space that contains the desired solution. To this end, we explore several trial wavefunctions to identify the most efficient parameterization of the molecular ground state. Taking advantage of known post-Hartree Fock quantum chemistry approaches and heuristic Hilbert space search quantum algorithms, we propose a new family of quantum circuits based on exchange-type gates that enable accurate calculations while keeping the gate count (i.e., the circuit depth) low. The particle-hole implementation of the Unitary Coupled Cluster (UCC) method within the Variational Quantum Eigensolver approach gives rise to an efficient quantum algorithm, named q-UCC , with important advantages compared to the straightforward 'translation' of the classical Coupled Cluster counterpart. In particular, we show how a single Trotter step can accurately and efficiently reproduce the ground state energies of simple molecular systems.

: We developed a new aramid-fiber white cane that is lightweight, resistant to breakage, and reduces injury caused by the cutting surface. This paper presents the results of evaluating the cane strength and the load on a user's muscles by comparing the new cane (aramid-fiber) with an existing one (carbon-fiber). Six male subjects participated in an experiment analyzing physical load reduction, in which the participants were required to wave a cane for 10 min using only wrist movement in a standing position. The surface electromyogram of five forearm muscles and the mental workload of the upper limb were analyzed. The results indicated that the new aramid-fiber white cane reduced the physical load on the muscles (flexor carpi radialis muscle, extensor carpi radialis muscle, flexor carpi ulnaris muscle, pronator teres muscle) by about 10~40% in comparison with the carbon-fiber white cane. However, the physical load on the extensor carpi ulnaris muscle, which is used during wrist extension, increases by about 30%.
