Pressure-induced structural phase transition in sulfur at 83 GPa.

The pressure-induced phase sequence of sulfur up to 90 GPa has been studied by an angle-dispersive x-ray-diffraction method. The orthorhombic sulfur (S-I) with S 8 cyclic molecules transforms to a high-pressure crystal phase (S-II) between 6 and 55 GPa. The second structural phase transition takes place at 83±2 GPa. The highest-pressure phase (S-III) can be explained as a base-centered orthorhombic lattice. This lattice is isomorphous to that in the metallic high-pressure phase of selenium. Metallization for sulfur reported by Luo et al. is ascribed to the second transition

Psychosocial determinants of relapse in ulcerative colitis: a longitudinal study

OBJECTIVES:To determine the association between psychosocial characteristics and time to relapse in patients with inactive ulcerative colitis.METHODS:Sixty patients with clinically and endoscopically inactive ulcerative colitis were followed for 1 yr, or less if they relapsed. Demographic, psychosocial, and clinical data were obtained. Stressful life events (Psychiatric Epidemiology Research Interview Life Events Scale), psychological distress (Symptom Checklist-90R), and perceived stress (Perceived Stress Scale) were recorded monthly by self-report. Multivariate time-dependent Cox regression was used to identify the independent determinants of earlier time to clinical relapse.RESULTS:The patients' mean age was 39 yr (SD = 9.4), 37 (62%) were female, and 22 (37%) relapsed during the 1-yr follow-up. Univariate Cox regression indicated a weak association between number of stressful events in the preceding month and time to relapse (p= 0.09). This association strengthened in multivariate analysis (p= 0.02, hazard ratio = 1.26 per event, 95% CI = 1.04–1.53) after adjustment for significant covariates.CONCLUSIONS:After controlling for demographic and clinical variables, more recent stressful events were associated with earlier time to relapse. These findings, which support a biopsychosocial model of disease, might help clinicians identify patients who might benefit from more intensive maintenance medical therapy and behavioral medicine interventions to reduce stress and improve coping.
Time to Revision of Primary THA Is Shorter for Specialists Than Nonspecialists

We asked if there was a shorter time to revision, and different indications for revision, for primary total hip arthroplasties performed in the community by general orthopaedic surgeons (nonspecialists) as compared with primary total hip arthroplasties performed by specialists. We retrospectively reviewed 560 revision total hip arthroplasties performed in 486 patients from 1998 to 2006 at our tertiary referral center. One hundred ninety revisions from the community (nonspecialists cohort) and 109 revisions for which the primary arthroplasty was performed by the specialists (specialist cohort) at our center met the criteria for inclusion. These cohorts were analyzed by the time to revision and the indications for revision. Our findings were that the specialists had a shorter mean time to revision (8.3 years versus 10.1 years). This result may reflect a greater concern by specialists over the potential complications of osteolysis as reflected by the finding that the indication for surgery was more often aseptic loosening for the nonspecialists (57.9% versus 12.8%) and osteolysis for the specialists (61.5% versus 15.8%). As a result of possible selection bias in cases referred by the non-specialists, the indications for revision may not represent the modes of failure for arthroplasties performed by nonspecialists.Level of Evidence: Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
Design of broadband antenna system for automatic dependent surveillance - broadcast

This paper deals with a design of a broadband patch antenna element for an ADS-B (Automatic Dependent Surveillance - Broadcast) system. An ADS-B system works on the frequencies of 1030 MHz and 1090 MHz. In this paper two types of patch antenna radiating elements have been described. An antenna synthesis of four radiating elements to obtain a higher system gain and better space coverage was performed. The paper contains a comparison between a numerical model in Matlab software, a computer model simulation in a CST Microwave Studio and a fabricated component.
Mechanism for Nucleocytoplasmic Shuttling of Histone Deacetylase 7*

Here we show that HDAC7, a member of the class II histone deacetylases, specifically targets several members of myocyte enhancer factors, MEF2A, -2C, and -2D, and inhibits their transcriptional activity. Furthermore, we demonstrate that DNA-bound MEF2C is capable of recruiting HDAC7, demonstrating that the HDAC7-dependent repression of transcription is not due to the inhibition of the MEF2 DNA binding activity. The data also suggest that the promoter bound MEF2 is potentially capable of remodeling adjacent nucleosomes via the recruitment of HDAC7. We have also observed a nucleocytoplasmic shuttling of HDAC7 and dissected the mechanism involved. In NIH3T3 cells, HDAC7 was primarily localized in the cytoplasm, essentially due to an active CRM1-dependent export of the protein from the nucleus. Interestingly, in HeLa cells, HDAC7 was predominantly nuclear. In these cells we could restore the cytoplasmic localization of HDAC7 by expressing CaMK I. This CaMK I-induced nuclear export of HDAC7 was abolished when three critical serines, Ser-178, Ser-344, and Ser-479, of HDAC7 were mutated. We show that these serines are involved in the direct interaction of HDAC7 with 14-3-3. Mutations of these serine residues weakened the association with 14-3-3 and dramatically enhanced the repression activity of HDAC7 in NIH3T3 cells, but not in HeLa cells. Data presented in this work clearly show that the signal dependent subcellular localization of HDAC7 is essential in controlling its activities. The data also show that the cellular concentration of factors such as 14-3-3, CaMK I, and other yet unknown molecules may determine the subcellular localization of an individual HDAC member in a cell type and HDAC-specific manner.

Evaluation of the Therapeutic Effect of Radioattenuated Yeast Cells in Experimental Paracoccidioidomycosis

Paracoccidioides brasiliensis is the agent of paracoccidioidomycosis (PCM), the most prevalent deep mycosis in Latin America. The treatment varies according to the chemotherapeutic drug and the disease severity, and the lack of it can results in high frequency of relapse and sequels. Thus, the search for new therapeutic alternatives is necessary. The aim of this study was to evaluate the therapeutic effect of P. brasiliensis yeast cells attenuated by gamma irradiation (LevRad) in Balb/c mice. Mice immunized with LevRad and/or treated with fluconazole presented a significant decrease in the CFU recovery from the lung, liver and spleen in comparison with non-immunized and non-treated infected mice (60 and 120 days after infection). After 120 days from fungal inoculation, no fungi colonies were obtained from the organs of treated and immunized mice. The tissue structure of these organs was largely preserved. At the same time, anti-Mexo specific IgG antibodies levels and TGF-β, IFN-γ, iNOS transcript levels were high and a decrease on the IL-4, IL-10 and TNF-α transcript levels was also verified. An additive protective effect of immunization with LevRad associated to chemotherapy in a PCM experimental model was verified, providing evidence of the therapeutic effect of attenuated yeast for fungal infections.
Potential of RFID Systems to Detect Object Orientation

In this paper we present a novel method for estimating the inclination of passive UHF RFID tags, for use in supply chains to monitor the handling of tagged items. Based on observations of the polarization, a Bayesian estimator of the tag inclination is constructed. The Bayesian estimator has been analyzed and evaluated in a experimental setup. The results shows great potential as the estimator is very robust when determining the inclination.
The frontoviki: soviet soldier-poets

This word refers to those who experienced the front, more specifically the front lines of the “Great Patriotic War” (the Soviet and then Russian name for the Second World War), whether they took part in the fights or accompanied the army as correspondents. Within the immense flow of texts which take the war as subject, we can thus distinguish the ones which, independently from their form (news reports, fiction, poetry), are legitimized by personal experience and for which their authors expose.
The Development of Experimental Allergic Encephalomyelitis with Immunizing Doses of Myelin Basic Protein

Summary Rabbits immunized with low (11.25 mg) and high (57.50 mg) doses of myelin basic protein from several species develop antibasic protein antibodies, delayed type hypersensitivity, and clinical and pathological signs of experimental allergic encephalomyelitis. More than 55% of rabbits immunized with relatively high doses of basic protein develop disease. The absence of circulating antibasic protein antibodies in immunorespondent animals is associated with the appearance of clinical or histologi-cal signs of experimental allergic encephalomyelitis; however, the presence of humoral antibodies did not prevent completely the development of disease. Delayed-type hypersensitivity, specific for the basic protein, appears as early as 5 days after immunization and is maintained in nondiseased and surviving animals. Neither excess encephalitogen nor encephalitogen-induced antibody is sufficient to suppress completely the eventual development of clinical or histological manifestations of disease.
Comparison of Bioleaching of Metals from Spent Petroleum Catalyst Using Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans

The present investigation deals with bioleaching of spent petroleum catalyst using At. ferrooxidans and At. thiooxidans. The spent catalyst used in the present study was pretreated with acetone to remove the oily hydrocarbons. FESEM and XPS analysis indicated the presence of metals in sulfide and oxide forms in spent catalyst. Both At. ferrooxidans and At. thiooxidans were found to be highly effective in producing the acid. Bioleaching with At. ferrooxidans and At. thiooxidans led to higher recovery of metals compare to control. During bioleaching similar recoveries of metals were obtained using At. ferrooxidans and At. thiooxidans. This might be due to the presence of metals as soluble oxides and sulphides in the spent catalyst. At the end of bioleaching, about 87-90% Ni, 34% Al, 65-73% Mo and 92-97% V were leached using above bacteria. It is elucidated that bioleaching with At. thiooxidans is comparatively more advantageous due to lower cost of sulphur. Keywords—Spent catalyst, At. ferrooxidans, Bioleaching, Metal recovery.
FDA panel urges “black box” warning for antidepressants

All antidepressants should come with a “black box” label warning that adolescents treated with the drugs are more likely to become suicidal, according to an advisory panel to the US Food and Drug Administration. Black box warnings are among the most stringent cautions issued by the FDA and are reserved for drugs with very serious or fatal side effects. The FDA generally follows the recommendations of advisory committees but is less likely to do so when the vote is split, as it was in this case (eight of the 23 expert panellists voted against the warning), said Dr Robert Temple, associate director for medical policy in the FDA's drug evaluation centre. The surprise vote came after the presentation of new analyses by the FDA during two days of hearings on 13 and 14 September showing that children taking …
Techno-Economic Contribution of FACTS Devices to the Operation of Power Systems With High Level of Wind Power Integration

The wind power integration in power networks impacts the operation of power systems economically and technically. The sites where wind power can be economically generated are determined by environmental conditions, so transmission congestion in the network may arise during certain periods. The issue of transmission congestion can become more acute if the network load is assumed to be rapidly growing at different sites during different times. This paper proposes novel, comprehensive methodology for realistic assessment of techno-economic merits of placement of thyristor-controlled series capacitors (TCSCs) and static VAr compensators (SVCs) in a transmission network to facilitate wind power integration. Economic considerations take into account the cost of generated active and reactive power, the cost of wind power integrationm and the cost of allocated FACTS devices for a range of operating conditions for several probabilistically modeled load growth profiles and over the lifetime of FACTS devices. The identification of congested areas and assessment of the financial benefits are carried out using optimal power flow-based algorithms. The placement of the TCSCs and SVCs is performed using novel genetic algorithms-based optimization with the net present value calculation integrated into the objective function.

Zur lernersprachlichen Generierung referierender Ausdrücke in argumentativen Texten

Die deutsche Sprache weist ein Artikelsystem auf, das definite und indefinite Artikel verwendet und anzeigt, ob der/die Sprecher/in ‐ der/die Produzent/in ‐ uber bekannte oder unbekannte Dinge etc. spricht. Artikel sind dabei Teile von Nominalphrasen, die sich auf Objekte o.a. beziehen und somit eine Referenz zu diesen Objekten ausdrucken. Mit Hilfe einer semantischen Analyse lassen sich vier verschiedene Typen der Referenz unterscheiden, die durch Nominalphrasen mit definiten und indefiniten Artikeln ausgedruckt werden. Fur L2-Lernende, deren Muttersprache kein entsprechendes Artikelsystem aufweist, stellt der Erwerb eines solchen Artikelsystems eine Herausforderung dar. Die semantische Klassifizierung der Artikel erlaubt in diesem Zusammenhang eine differenzierte Fehleranalyse. In unserem Beitrag gehen wir den Fragen nach, inwiefern die Artikelwahl von L2-Lernenden mit L1 Chinesisch mit der Artikelwahl in Deutsch als L1 ubereinstimmt und inwiefern sich aufgestellte Hypothesen zur Artikelverwendung bei L2-Lernenden bestatigen lassen. Es handelt sich hierbei um die Untersuchung argumentativer L2-Texte im Rahmen eines umfassenderen Projekts zur korpusbasierten Untersuchung von Lernersprache. Unter Lernerkorpus verstehen wir in Anlehnung an Granger (2002: 7) eine Sammlung von geschriebenen oder gesprochenen Auserungen von Fremdsprachenlernenden in der L2, die auf Rechnern gespeichert und maschinenlesbar sind und die fur eine linguistische und fremdsprachendidaktische Auswertung aufbereitet sind. Lernerkorpora werden in der Fremdsprachendidaktik insbesondere fur die ‐ v.a. qualitative ‐ Erstellung von Fehlertypologien sowie fur den systematischen ‐ v.a. quantitativen ‐ Vergleich von L1- und L2-Texten eingesetzt. Daraus lassen sich spezifische problembezogene Losungen fur die Fremdsprachendidaktik ableiten (Romer 2008). Ein Beispiel eines bekannten Lernerkorpus im Bereich Deutsch als Fremdsprache ist das Fehlerannotierte Lernerkorpus FALKO (FALKO [online]). Das ALeSKo-Korpus (= Annotiertes Lernersprachenkorpus), auf dessen Daten die vorliegende Untersuchung beruht, ist seit 2009 im Aufbau befindlich. Den Kern des Lernerkorpus bilden argumentative Texte chinesischer Deutschlernen
Competitive Enzyme-Linked Immunosorbent Assay Based on a Rhoptry-Associated Protein 1 Epitope Specifically Identifies Babesia bovis-Infected Cattle

ABSTRACT The competitive enzyme-linked immunosorbent assay (cELISA) format has proven to be an accurate, reliable, easily standardized, and high-throughput method for detecting hemoparasite infections. In the present study, a species-specific, broadly conserved, and tandemly repeated B-cell epitope within the C terminus of the rhoptry-associated protein 1 of the hemoparasite Babesia bovis was cloned and expressed as a histidine-tagged thioredoxin fusion peptide and used as antigen in a cELISA. The assay was optimized with defined negative and positive bovine sera, where positive sera inhibited the binding of the epitope-specific monoclonal antibody BABB75A4. The cELISA accurately differentiated animals with B. bovis-specific antibodies from uninfected animals and from animals with antibodies against other tick-borne hemoparasites (98.7% specificity). In addition, B. bovis-specific sera from Australia, Argentina, Bolivia, Puerto Rico, and Morocco inhibited the binding of BABB75A4, confirming conservation of the epitope. The assay first detected experimentally infected animals between 13 and 17 days postinfection, and with sera from naturally infected carrier cattle, was comparable to indirect immunofluorescence (98.3% concordance). The assay appears to have the characteristics necessary for an epidemiologic and disease surveillance tool.
Ajustes Dinámicos en las Tasas de Paro: España vs. Portugal

En este trabajo se aborda la diferencia entre la tasa de desempleo en Espana y Portugal. Las teorias tradicionales explican los movimientos del desempleo como resultado de los movimientos de la Tasa Natural de Paro o como resultado de shocks temporales con efectos permanentes sobre el desempleo, bajo la hipotesis de histeresis. En este trabajo, se sigue el enfoque de la TeorIa de la Reaccion en Cadena, que interpreta los movimientos del desempleo como resultado de la interaccion de un conjunto de procesos de ajuste retardado presentes en el mercado de trabajo con las caracteristicas dinamicas de los shocks. En este contexto, encontramos que el desempleo puede haber crecido mas en Espana que en Portugal debido a los largos periodos de ajuste necesarios para interiorizar los efectos de un shock temporal, mientras que los efectos de los shocks permanentes necesitan largos periodos de tiempo para manifestarse. Por ultimo, encontramos que el aumento de la tasa de paro espanola no puede justificarse tan solo en terminos de un aumento de la tasa natural, ya que mas del 57% del cambio total entre 1980 y 1995 se debe a los procesos de ajuste.
Somatostatin and somatostatin subtype 2A expression in the mammalian retina

This review discusses the expression and cellular localization of the neuropeptide somatostatin (SRIF) and one of the SRIF subtype (sst) receptors, sst2A in the mammalian retina. SRIF immunoreactivity is predominantly localized to a sparse population of amacrine and displaced amacrine cells in the ganglion cell layer in several mammalian retinas including the rat, rabbit, cat, and primate. These cells, characterized by multiple processes, form a sparse network in the inner plexiform layer (IPL) in all retinal regions. Very few processes are also in the outer plexiform layer. In contrast to the predominant distribution of SRIF processes to the IPL, there is a widespread distribution of sst2A immunoreactivity to both the inner and outer retina in all mammalian retinas studied to date. In rabbit retina, sst2A immunoreactivity is predominant in rod bipolar cells and in sparse wide‐field amacrine cells. In the rat retina, sst2A immunoreactivity is localized to several neuronal cell types—cone photoreceptors, horizontal cells, rod and cone bipolar cells, and amacrine cells. Reverse‐transcriptase–polymerase chain reaction analysis found that sst2A mRNA is expressed in the rat retina, while sst2B mRNA is not detected. Finally, in the primate retina sst2 immunoreactivity is predominant in cone photoreceptors, with additional immunostained cell bodies and processes in the inner retina. These findings indicate that SRIF may modulate several neuronal cell types in the retina, and that it has a broad influence on both scotopic and photopic visual pathways. Microsc. Res.

WATER LEVEL MONITORING AND CONTROL USING FUZZY LOGIC SYSTEM

This study is on water level monitoring and control using fuzzy logic. There are various approaches to the design of the level controllers. The Proportional Integral Derivative (PID) controllers have turn out to be famous for level control. But at low power operations, Proportional-Integral- Derivative (PID) controllers cannot maintain liquid level properly, thus, the need for performance improvement in the existing liquid level regulators became paramount. In this research, a controller based on fuzzy logic was implemented. Fuzzy Logic Controller is easy to implement than PID controller. Additionally, the Fuzzy Logic Controller can be easily programmed into many currently available industrial process controllers. Unlike the conventional PID controller the Fuzzy Logic Controller has benefits on the system response. The Fuzzy Logic Controller on a level control problem with promising results can be applied to an entirely different industrial level controlling apparatus.
