Developing an index model for flood risk assessment in the western coastal region of Mazandaran, Iran | Abstract This paper represents an index model developed for the assessment of risk caused by river floods. The main purpose of this model is to evaluate the flood risk in the western coastal region of Mazandaran Province/Iran. The model assesses the risk at triple components, i.e. the flood occurrence probability, vulnerability and consequences, through identification and evaluation of effective criteria categorized into seven indexes (environmental, technical, economic, social, depth, population and sensitivity ones) that are involved in all stages of flooding (source, pathway and receptor). The flood risk in the developed model is defined by a dimensionless magnitude called as risk score between 0 and 100 for each zone of the area under assessment by calculating and combining of two newly defined factors: occurrence and vulnerability factor and impact factor. The model was applied in a case study, the Nowshahr flood in 2012. The results showed that: (i) the flood risk zoning was compared with observed data for aspect of the damages, and general agreement between them was obtained; (ii) for urban zones, which surrounded by two rivers, would easily be in critical condition and rescue operations face difficulties; and (iii) it is necessary to review the location of the emergency services, according the flood risk zoning. | Journal of Hydrology and Hydromechanics | [

Activities of α-ketoisovalerate, pyruvate, and α-ketoglutarate dehydrogenases in a mutant of Bacillus subtilis | An acetate-requiring leaky mutant was induced from Bacillus subtilis 168, and activities of its three α-keto acid dehydrogenases were compared with the respective activities of the parent strain. Both pyruvate and α-ketoisovalerate dehydrogenase activities in the mutant were considerably lower, being only 10–17% of those of the parent, but α-ketoglutarate dehydrogenase activity was unchanged. These dehydrogenases are complexes composed of three enzymes: a carboxylase, a lipoic reductase–transacylase, and a dihydrolipoyl dehydrogenase. The carboxylase activity of the affected complexes was no different. Total dihydrolipoyl dehydrogenase activity was only one-third. Thus dihydrolipoyl dehydrogenase is the defective enzyme in the two dehydrogenase complexes; the activity remaining in the mutant is accounted for by the activity of the intact α-ketoglutarate dehydrogenase. | [

5-HT Obesity Medication Efficacy via POMC Activation is Maintained During Aging | Abstract The phenomenon commonly described as the middle-age spread is the result of elevated adiposity accumulation throughout adulthood until late middle-age. It is a clinical imperative to gain a greater understanding of the underpinnings of age-dependent obesity and, in turn, how these mechanisms may impact the efficacy of obesity treatments. In particular, both obesity and aging are associated with rewiring of a principal brain pathway modulating energy homeostasis, promoting reduced activity of satiety pro-opiomelanocortin (POMC) neurons within the arcuate nucleus of the hypothalamus (ARC). Using a selective ARC-deficient POMC mouse line, here we report that former obesity medications augmenting endogenous 5-hydroxytryptamine (5-HT) activity d-fenfluramine and sibutramine require ARC POMC neurons to elicit therapeutic appetite-suppressive effects. We next investigated whether age-related diminished ARC POMC activity therefore impacts the potency of 5-HT obesity pharmacotherapies, lorcaserin, d-fenfluramine, and sibutramine and report that all compounds reduced food intake to a comparable extent in both chow-fed young lean (3–5 months old) and middle-aged obese (12–14 months old) male and female mice. We provide a mechanism through which 5-HT anorectic potency is maintained with age, via preserved 5-HT–POMC appetitive anatomical machinery. Specifically, the abundance and signaling of the primary 5-HT receptor influencing appetite via POMC activation, the 5-HT2CR, is not perturbed with age. These data reveal that although 5-HT obesity medications require ARC POMC neurons to achieve appetitive effects, the anorectic efficacy is maintained with aging, findings of clinical significance to the global aging obese population. | [

Shorter serial intervals in SARS-CoV-2 cases with Omicron BA.1 variant compared with Delta variant, the Netherlands, 13 to 26 December 2021 | The SARS-CoV-2 Omicron variant has a growth advantage over the Delta variant because of higher transmissibility, immune evasion or shorter serial interval. Using S gene target failure (SGTF) as indication for Omicron BA.1, we identified 908 SGTF and 1,621 non-SGTF serial intervals in the same period. Within households, the mean serial interval for SGTF cases was 0.2–0.6 days shorter than for non-SGTF cases. This suggests that the growth advantage of Omicron is partly due to a shorter serial interval. | Eurosurveillance | [

Gestão de efluentes de banheiros químicos: uma revisão das abordagens internacionais e um estudo de caso em Minas Gerais | RESUMO Os banheiros químicos são uma solução largamente utilizada como alternativa ao esgotamento sanitário de lugares onde não há acesso à rede coletora de esgoto, principalmente eventos públicos e frentes de trabalho móveis. Nesses banheiros é comum a adição de substâncias desodorizantes com os intuitos de inibir a atividade microbiológica do meio e minimizar os maus odores gerados pela ação microbiana. Os desodorizantes aplicados possuem surfactantes, essências aromáticas e corantes, além de princípios ativos usados na inibição da atividade microbiológica, como o formaldeído, composto carcinogênico. A gestão dos efluentes de banheiros químicos no Brasil ainda é -incipiente, existindo relatos de descarte clandestino em rios e sistemas de drenagem, trazendo consequências à saúde pública e ao meio ambiente. Existem poucos estudos sobre a caracterização desses efluentes e os possíveis impactos gerados em estações de tratamento de esgoto convencionais que realizam o recebimento desses resíduos. Por tais motivos, este estudo avaliou a gestão, o transporte e a destinação final dos efluentes de banheiros químicos, os desodorizantes empregados e as regulamentações brasileiras e mineiras. Além disso, apresentou um cenário para discussão, utilizando metodologias qualitativas e quantitativas de pesquisa, tais como a aplicação de entrevistas estruturadas e semiestruturadas e análise documental. Os resultados obtidos neste estudo indicam que não há consenso sobre as melhores práticas de manejo e gestão dos efluentes de banheiros químicos, impactando em sua regulamentação em níveis estaduais e, sobretudo, nacionais. Portanto, observa-se que deve haver uma melhoria no controle ambiental do setor, principalmente no que diz respeito à regulação dos serviços de recebimento de material por parte das estações de tratamento de esgoto. | [

Peroxisome Proliferator-Activated Receptor-γ Ameliorates Pulmonary Arterial Hypertension by Inhibiting 5-Hydroxytryptamine 2B Receptor | An elevated plasma level of 5-hydroxytryptamine (5-HT) or upregulation of 5-HT receptor signaling or both is implicated in vascular contraction and remodeling in pulmonary arterial hypertension (PAH). Recently, peroxisome proliferator-activated receptor-γ (PPARγ) agonists have been shown to ameliorate PAH. However, their effects on the 5-HT-induced contraction of pulmonary arteries remain unknown. Here, we examined the role of PPARγ in inhibiting 5-HT2B receptor (5-HT2BR) to ameliorate PAH. Pulmonary arteries from PAH rats induced by monocrotaline or chronic hypoxia showed an enhanced vasoconstriction in response to BW723C86, a specific agonist for 5-HT2BR. Expression of 5-HT2BR was also increased in pulmonary arteries from the PAH rats, accompanied by vascular remodeling and right ventricular hypertrophy. Treatment with the PPARγ agonist rosiglitazone in vivo reversed the expression and the vasocontractive effect of 5-HT2BR as well as the thickening of pulmonary arteries. In pulmonary artery smooth muscle cells, 5-HT induced the gene expression of 5-HT2BR, which was inhibited by rosiglitazone, pioglitazone, or adenovirus-mediated overexpression of constitutively activated PPARγ. The pharmacological effect of PPARγ was through the suppression of the 5-HT-induced activator protein-1 activity. These results demonstrated the beneficial effect of PPARγ on 5-HT2BR-mediated vasocontraction, providing a new mechanism for the potential use of PPARγ agonists in PAH. | [

THE PATHOGENESIS OF EXPERIMENTAL COLITIS, AND THE RELATION OF COLITIS IN ANIMALS AND MAN | 1. The facts described in this paper are intended to bear upon the pathogenesis of colitis in man and animals. 2. The toxin of the Shiga dysentery bacillus is liberated from the bacillus through the process of autolysis. 3. In rabbits the toxin is not absorbed directly in an active form by the gastro-intestinal tract; in man, however, absorption of an active poison does take place from the intestine. 4. The toxin is excreted in rabbits, and probably in man as well by the intestine, chiefly probably by the large intestine, which being injured by the act of elimination, reacts by the development of inflammation, etc. 5. In rabbits the characteristic action of the toxin depends upon the integrity of the biliary secretion into the intestine. When the bile is prevented from entering the intestine, either by ligature and section of the duct or by establishment of a biliary fistula, no lesions whatever of the large intestine appear, or they are inconsiderable in extent. 6. The loss of toxin through a biliary fistula does not prevent in rabbits the lethal effects which are caused, apparently, by a nervous poison. The tying off of the bile duct seems to prevent the passage of the toxin, in amounts sufficient to cause the large intestinal lesions, into the blood. The liver, therefore, in this condition tends to hold back the toxin from the general circulation. 7. The peculiar effects of the toxin on the large intestine in rabbits is not produced at once, but would appear to depend upon successive acts of excretion of the poison by the bowel. 8. The establishment of biliary fistula reduces the intensity of action of corrosive sublimate upon the large intestine in rabbits; and the lesions of ricin poisoning in these animals are also modified by this operation. 9. Dysentery toxin is destroyed by peptic digestion, and also, though probably more slowly, by tryptic digestion. The absence of power of the toxin to cause poisoning in rabbits when it is brought directly into the lumen of the intestine, is not explained by the destructive action of trypsin. 10. The character of the histological changes in the cæcum of rabbits caused by the dysentery toxin points to an action upon the substance and not primarily upon the surface of the intestine. | [

Protection effects on fish assemblages, and comparison of two visual-census techniques in shallow artificial rocky habitats in the northern Adriatic Sea | Fish assemblages associated with shallow (4–7 m deep) artificial rocky habitats (i.e. breakwaters) have been assessed between July 2002 and September 2003, at the marine protected area of Miramare and adjacent areas outside the reserve (northern Adriatic sea). Our purpose was to: (1) detect possible differences between ‘protected vs fished’ breakwaters; and (2) compare two visual-census techniques for fish assessment (i.e. strip transects vs stationary points). The fish assemblages observed between protected and fished breakwaters during all four sampling periods were statistically different. More fish taxa were found at the protected than fished breakwaters, while there was no difference in total fish density. Most fish species targeted by fisheries had a greater density (e.g. Sciaena umbra, Dicentrarchus labrax, Sparus aurata, Diplodus vulgaris, Diplodus sargus and Diplodus puntazzo) and/or size (e.g. S. aurata and D. annularis) at the protected than fished breakwaters. There was a significant difference in fish assemblages due to assessment method. In general, the number of taxa was greater when assessed by strip transects than stationary points. Total fish density was almost unaffected by the method used, while total density of demersal fish (i.e. excluding schooling species) tended to be greater when evaluated by strip transects, although the difference was statistically significant only in one sampling period out of four. These results indicate that protection from fishing may have the potential to influence fish assemblages associated with breakwaters. Additionally, caution should be used when comparing fish assemblage data collected by different visual assessment techniques. | [

NADA DE NOVO TANTO NO FRONT QUANTO NO MUNDO | Resumo: Nada de novo no front, de Erich Maria Remarque, é o relato de um soldado raso alemão, Paul Bäumer, que vivenciou o cotidiano da I Guerra Mundial. Quando foi publicado, em 1929, esse livro questionou até que ponto a pátria poderia dispor de seus cidadãos a fim de colocar em prática decisões elaboradas por lideranças políticas no conforto de seus gabinetes. Por mais que o romance seja uma realidade paralela criada por um escritor, a trama baseia-se em fatos reais, refletindo acontecimentos históricos e trazendo memórias que os livros didáticos não conseguem alcançar. As descrições dos mais intensos sofrimentos, como a fome, o frio, o medo e a morte formam um panorama do que realmente foi o primeiro maior conflito do século XX, diferentemente da visão dada pelos articuladores desse embate. O embrutecimento do ser, a impossibilidade de perspectiva quanto ao futuro e a noção da falta de sentido dos conflitos são o mote desse romance, que capitaneou a lista das literaturas distópicas, advindas do desencanto em relação ao mundo, ao progresso científico e ao ser humano. Palavras-chave: Nada de novo no front. Literatura. Distopia. I Guerra Mundial. Abstract: All Quiet on the Western Front, by Erich Maria Remarque, is the story of a German Private, Paul Bäumer, who experienced the daily living of the 1st World War. When it was published, this book questioned to what extent a country could use their citizens in order to put into practice the decisions taken by political leaders in the comfort of their offices. Although the novel depicts a parallel reality created by a writer, the plot is based on true facts, reflecting historic happenings and bringing memories which the textbooks are not able to reach. The descriptions of the most intense sufferings, such as hunger, coldness, fear and death, create a picture of what was the first real major conflict of the XX century, a vision totally different from the one held by the articulators of this war. The brutalization of the human being, the impossibility of finding a perspective for the future and the notion of lack of sense of these conflicts are the motto of this novel, a work which leaded the list of dystopian books resulting from the disillusion with the world, the scientific progress and the human being. Keywords: All Quiet on the Western Front. Literature. Dystopia. 1st World War | [

Stochastic Volatility in the Peruvian Stock Market and Exchange Rate Returns: A Bayesian Approximation | This study is one of the first to utilize the stochastic volatility (SV) model to modelling the Peruvian financial times series. We estimate and compare this model with generalized autoregressive conditional heteroscedasticity (GARCH) models with normal and t-student errors. The analysis in this study corresponds to Peru’s stock market and exchange rate returns. The importance of this methodology is that the adjustment of the data is better than the GARCH models, using the assumptions of normality in both models. In the case of the SV model, three Bayesian algorithms have been employed where we evaluate their respective inefficiencies in the estimation of the model’s parameters—the most efficient being the integration sampler. The estimated parameters in the SV model under the various algorithms are consistent, as they display little inefficiency. The figures of the correlations of the iterations suggest that there are no problems at the time of Markov chaining in all estimations. We find that the volatilities in the exchange rate and stock market volatilities follow similar patterns over time. That is, when economic turbulence caused by the economic circumstances occurred, for example, the Asian crisis and the recent crisis in the USA, considerable volatility was generated in both markets.

Auditor Style and Financial Reporting Similarity | ABSTRACT In this study, we examine whether auditor style is related to financial reporting similarity. Based on the count of accounting items disclosed in eXtensible Business Reporting Language (XBRL) 10-K filings, we define financial reporting similarity in terms of the number of similar line items reported by a pair of firms and develop a measure of pairwise financial reporting similarity. Consistent with the auditor style literature (e.g., Francis, Pinnuck, and Watanabe 2014), we show that firms that share the same auditor have more similarities in their financial statements. We find robust results using alternative metrics of auditor style, including pairwise comovement of audit fees and audit timeliness. We also find that financial reporting similarity increases (decreases) when firms switch from having different (the same) auditors to having the same (different) auditors. | [

Computer Simulation Results for Planar Reflectors and Flat Plate Solar Collectors | The benefits attributed to reflectors for increasing performance of flat plate collectors vary quite widely in the literature. In the present study, a detailed computer simulation is carried out to investigate the increase in performance. The results show that: Collectors should be placed at a higher tilt angle than usual; reflectors placed in front of the collectors can be tilted up 5 or 10 deg; and performance has a broad peak with respect to tilt angle. The system performance enhancement in Salt Lake City, Utah ranges from 1.16 for domestic hot water to 1.28 for space heating for equal reflector-collector areas, and the break even ratio of per area reflector to collector cost is from 16 to 28 percent for these systems. | Journal of Solar Energy Engineering | [

Coronal heating and flaring in QSLs | AbstractQuasi-Separatrix Layers (QSLs) are 3D geometrical objects that define narrow volumes across which magnetic field lines have strong, but finite, gradients of connectivity from one footpoint to another. QSLs extend the concept of separatrices, that are topological objects across which the connectivity is discontinuous. Based on analytical arguments, and on magnetic field extrapolations of the Sun's coronal force-free field above observed active regions, it has long since been conjectured that QSLs are favorable locations for current sheet (CS) formation, as well as for magnetic reconnection, and therefore are good predictors for the locations of magnetic energy release in flares and coronal heating. It is only up to recently that numerical MHD simulations and solar observations, as well as a laboratory experiment, have started to address the validity of these conjectures. When put all together, they suggest that QSL reconnection is involved in the displacement of EUV and SXR brightenings along chromospheric flare ribbons, that it is related with the heating of EUV coronal loops, and that the dissipation of QSL related CS may be the cause of coronal heating in initially homogeneous, braided and turbulent flux tubes, as well as in coronal arcades rooted in the slowly moving and numerous small-scale photospheric flux concentrations, both in active region faculae and in the quiet Sun. The apparent ubiquity of QSL-related CS in the Sun's corona, which will need to be quantified with new generation solar instruments, also suggests that QSLs play an important role in stellar's atmospheres, when their surface radial magnetic fields display complex patterns. | [

Thermomechanical effects on phase transformations in single-crystal Cu–Al–Ni shape-memory alloy | Single-crystal rods of Cu–Al–Ni shape-memory alloy fabricated from a molten pool of 82 wt% Cu, 14 wt% Al, and 4 wt% Ni by the Czochralski method were first heated to ∼870 °C and then quenched to obtain austenitic microstructures. Various microanalysis techniques were used to determine the chemical composition, microstructure, and phase-transformation temperatures of the produced alloy. Cyclic tensile tests with in situ temperature control demonstrated the occurrence of pseudoelastic deformation at elevated and close to phase-transformation temperatures and provided insight into the temperature dependence of the phase-transformation stress, damping characteristics, and cyclic straining of single-crystal Cu–Al–Ni alloy. The stress hysteresis observed in the pseudoelastic deformation cycles decreased at elevated temperatures. The stress response at different temperatures is associated with the formation, growth, and coalescence of martensite variants. Stress-induced phase-transformation mechanisms, coalescence of twin variants, and energy dissipation by pseudoelastic deformation are discussed in the context of experimental findings. The results illustrate the potential of single-crystal Cu–Al–Ni as a structural material for dynamic microsystems and temperature sensors. | [

A system for generating transcription regulatory networks with combinatorial control of transcription | Abstract Summary: We have developed a new software system, REgulatory Network generator with COmbinatorial control (RENCO), for automatic generation of differential equations describing pre-transcriptional combinatorics in artificial regulatory networks. RENCO has the following benefits: (a) it explicitly models protein–protein interactions among transcription factors, (b) it captures combinatorial control of transcription factors on target genes and (c) it produces output in Systems Biology Markup Language (SBML) format, which allows these equations to be directly imported into existing simulators. Explicit modeling of the protein interactions allows RENCO to incorporate greater mechanistic detail of the transcription machinery compared to existing models and can provide a better assessment of algorithms for regulatory network inference. Availability: RENCO is a C++ command line program, available at http://sourceforge.net/projects/renco/ Contact: terran@cs.unm.edu Supplementary information: Supplementary data are available at Bioinformatics online. | [
