Description of two new species of Martarega White, 1879 (Heteroptera: Nepomorpha: Notonectidae), one based on the mixed type-series of M. oriximinaensis Barbosa, Ribeiro & Ferreira-Keppler, 2010. Martarega currently includes 20 species restricted to the Americas. A mixed type-series of M. oriximinaensis from Brazil was detected, including males with an additional group of ensiform bristles on the fore trochanter and mesofemur conspicuously setose. These specimens were described as a new species, M. siolii Barbosa, Nessimian & Takiya, sp. nov., and a redescription of M. oriximinaensis is also given. A second new species from Colombia is described, M. guajira Barbosa, Nessimian & Takiya, sp. nov. This species is very similar to M. pacifica, except for having groups of ensiform setae on the fore- and mesotrochanter, and an additional opaque area on the hemelytra.

In this study, we randomly compared high doses of the tyrosine kinase inhibitor imatinib combined with reduced-intensity chemotherapy (arm A) to standard imatinib/hyperCVAD (cyclophosphamide/vincristine/doxorubicin/dexamethasone) therapy (arm B) in 268 adults (median age, 47 years) with Philadelphia chromosome–positive (Ph+) acute lymphoblastic leukemia (ALL). The primary objective was the major molecular response (MMolR) rate after cycle 2, patients being then eligible for allogeneic stem cell transplantation (SCT) if they had a donor, or autologous SCT if in MMolR and no donor. With fewer induction deaths, the complete remission (CR) rate was higher in arm A than in arm B (98% vs 91%; P = .006), whereas the MMolR rate was similar in both arms (66% vs 64%). With a median follow-up of 4.8 years, 5-year event-free survival and overall survival (OS) rates were estimated at 37.1% and 45.6%, respectively, without difference between the arms. Allogeneic transplantation was associated with a significant benefit in relapse-free survival (hazard ratio [HR], 0.69; P = .036) and OS (HR, 0.64; P = .02), with initial white blood cell count being the only factor significantly interacting with this SCT effect. In patients achieving MMolR, outcome was similar after autologous and allogeneic transplantation. This study validates an induction regimen combining reduced-intensity chemotherapy and imatinib in Ph+ ALL adult patients and suggests that SCT in first CR is still a good option for Ph+ ALL adult patients. This trial was registered at www.clinicaltrials.gov as #NCT00327678.
Diet, exercise or diet with exercise: comparing the effectiveness of treatment options for weight-loss and changes in fitness for adults (18–65 years old) who are overfat, or obese; systematic review and meta-analysis
Authors: Clark James E
Published: April 2015

There are number of means of methods to alter body composition, and metabolic issues, available for the adult who is overfat. The following is a systematic review and meta-analysis focused on comparing changes from treatment program for adults who are overfat based on analysis of aggregated effect size (ES) of inducing changes. So as to determine the relative effectiveness of such protocols and intervention plans of choice. This tiered meta-analysis of 66-population based studies, and 162-studywise groups, a clear pattern of ES being established across and within treatments. First, hypocaloric balance is necessary for changing body composition, but the effectiveness for establishing imbalance does not equate with the effectiveness for body compositional changes, or any biomarkers associated with metabolic issues. With analysis showing that there is a necessity to include exercise in combination with diet effectively elicit changes in body composition and biomarkers of metabolic issues. More importantly, the combination, resistance training (RT) was more effective than endurance training (ET) or combination of RT and ET, particularly when progressive training volume of 2-to-3 sets for 6-to-10 reps at an intensity of ≥75% 1RM, utilizing whole body and free-weight exercises, at altering body compositional measures (ES of 0.47, 0.30, and 0.40 for loss of BM, FM, and retention of FFM respectively) and reducing total cholesterol (ES = 0.85), triglycerides (ES = 0.86) and low-density lipoproteins (ES = 0.60). Additionally RT was more effective at reducing fasting insulin levels (ES = 3.5) than ET or ET and RT. Even though generally lower ES than RT, the inclusion of ET was more effective when performed at high intensity (e.g. ≥70% VO2max or HRmax for 30-minutes 3-4x’s/wk), or in an interval training style than when utilizing the relatively common prescribed method of low-to-moderate (e.g., 50-70% VO2max or HRmax for at least equal time) steady state method, ES of 0.35, 0.39, and 0.13 for BM, FM, and FFM respectively. Thus indicating that focus of treatment should be on producing a large metabolic stress (as induced by RT or high levels of ET) rather than an energetic imbalance for adults who are overfat.

“I know I’m a good mum – no one can tell me different.” Young mothers negotiating a stigmatised identity through time
Authors: Wenham Aniela
Published: April 2015

This article draws on qualitative longitudinal data obtained over a five-year period with young mothers. What makes the approach described in this article unique is how it views teenage pregnancy and motherhood as fluid and dynamic, moving away from the static snapshots that often depict young mothers as struggling (or ‘failing’) at one moment in time, to a more nuanced account that reflects their journeys into motherhood and the changes that occur through time. Three main themes are explored. First, emphasis is placed on the acute awareness of stigmatisation and how the women in the study consequently felt pressure to ‘prove’ that they were different or set apart from the stereotypical teenage mother. Second, factors that either neutralise or exacerbate the experience of stigma are explored. Finally, it is argued that greater attention should be paid to the process of stigmatisation through the notion of a ‘maternal career’. This framework allows for an appreciation of both the complexity of how lives unfold and of the many factors that can influence its direction.

Authors: Stadlerová Hana
Published: April 2015

The paper presents the possibilities of developing the psychodidactic skills of students participating in a new pedagogical practicum conducted by the Department of Art of Masaryk University in Brno. Special art education (SAE), a program primarily designed for sociallydisadvantaged clients, imposes specific requirements on leading art activities. The students became part of a qualitative research program, which was implemented from 2010 to 2013 and which helped to articulate which psycho-didactic skills each student already had; this was accomplished through the implementation of specific art activities with clients from five participating institutions. The paper presents a part of the results of the research.

Published: April 2015

In contrast to a normal gait, the locomotion of people with infantile cerebral palsy (ICP) is characterized by great variability. An experiment was conducted to determine if the use of whole-body vibrations changes the time of support by each of the extremities as well as the range of flexion of the hip and knee articulations. Three women with ICP were involved in the whole-body vibration experiment. The parameters of the vibration adopted during training were a frequency of 20 Hz and an amplitude of 2 mm. The BTS Smart system for three-plane movement analysis paired with a desktop computer was used for the evaluation of gait parameters. The vibration procedure improved the range of flexion in knee articulation but did not change the range of flexion in hip articulation. The equalization of time disparities in the load of both extremities was obtained after the first treatment procedure. In this investigated group, the vibration procedure may be a complement to the rehabilitation process.

We report two newborns with female external genitalia and bilateral inguinal swelling who were diagnosed with 17β-hydroxysteroid dehydrogenase type 3 deficiency, a rare cause of 46,XY disorder of sexual development. The first case had normal clitoral size and vaginal and urethral openings, palpable gonads in the inguinal region, low testosterone, and low levels of basal and GNRH-stimulated gonadotropin. The second case had similar external genitalia, low testosterone but borderline basal and normal stimulated gonadotropin levels. Low testosterone/androstenedione ratios (0.22 and 0.24, respectively; normal, >0.8) after human chorionic gonadotropin stimulation indicated 17β-hydroxysteroid dehydrogenase type 3 deficiency.
Subclinical hypothyroidism as a rare cofactor in chronic kidney disease (CKD) – related anemia
Authors: Bargenda Agnieszka , Musiał Kinga , Zwolińska Danuta
Published: April 2015

Both chronic kidney disease (CKD) and hypothyroidism may cause anemia. However, the combination of the three above-mentioned phenomena in children has not been described yet.

Our aim was to present a case of a 16-year-old girl hospitalized due to the renal impairment in the course of chemotherapy. Chronic kidney disease and severe anemia were diagnosed and erythropoiesis-stimulating agents (ESA) were administered. In view of unsatisfactory therapeutic effect, rare potential causes of hyporesponsiveness to ESA were analyzed. Laboratory tests revealed subclinical hypothyroidism. The thyroid hormone replacement therapy was applied and normalization of thyroid function was observed. Further increase of hemoglobin levels permitted discontinuation of ESA treatment. At the same time, partial amelioration of kidney function, as well as clinical improvement, were noticed.

The thyroid gland function should be assessed both in differential diagnostics of anemia and in case of unsatisfactory treatment with ESA.

Grafting poly(2-acryloyloxyethyl trimethyl ammonium chloride) branches onto the backbones of corn starch for toughening starch film
Authors: Zhu Zhifeng , Zhu Zhongqiu , Zhang Linyan
Published: April 2015

This work was undertaken to examine the effect of poly(2-acryloyloxyethyl trimethyl ammonium chloride) (PATAC) branches grafted onto the backbones of starch on the toughening of starch film. A series of starch-g-PATAC samples having different levels of grafting ratio were prepared by the graft copolymerization of granular corn starch with ATAC in an aqueous system, using Fenton’s initiator through changing the weight ratio of the monomer to starch. The influences of grafted branches on the properties such as tensile strength, breaking elongation, work-to-break, bending endurance, moisture regain, swelling power, and solubility of starch film were evaluated by comparison with those of acid-treated starch (ATS). It was found that the branches were able to toughen starch film due to the significant increases in breaking elongation, work-to-break and bending endurance of the film. The branches were also able to increase its moisture regain, water swelling power, and solubility. In addition, the properties were dependent on the amount of the branches. Furthermore, the grafted starch was biodegradable when its grafting ratio did not exceed 7.5 wt%.

Weimar steht plötzlich wieder auf der Agenda. Gab es doch mehr Demokraten als bisher angenommen, war das Zukunftspotenzial doch größer? Eng mit solchen Fragen verbunden ist das Problem der „Handlungsspielräume“ der Regierung, das vor zwei, drei Jahrzehnten in einer der faszinierendsten und komplexesten Debatten der deutschen Zeitgeschichte, der sogenannten Borchardt-Debatte, im Zentrum stand. Paul Köppen und Tim B. Müller haben in den Vierteljahrsheften für Zeitgeschichte die Weimar- und Borchardt-Debatte wiederbelebt und damit auch die Politik von Reichskanzler Heinrich Brüning erneut auf den Prüfstand gestellt. Roman Köster, Historiker an der Universität der Bundeswehr in München, setzt sich mit ihren Argumenten kritisch auseinander. Er bietet ebenso souverän Orientierung wie Knut Borchardt, der im selben Heft zu Wort kommt.
Logics of Lifestyle and the Rise of Scripps Networks, 1994–2010
Authors: Ryan Maureen
Published: April 2015

This article examines the “turn to lifestyle” in the longstanding genres of how-to and domestic advice programming, which began in 1994 with the launch of Home & Garden Television (HGTV) and the Food Network. It frames lifestyle's spread across the growing cable television system in the late 1990s and 2000s as the result of industrial conditions that favored the growth and consolidation of cable networks, as well as growing cultural interest in “lifestyle” as a consumerist form of identity. In this context, a turn to lifestyle in programming offered the new networks HGTV and Food Network a way to broaden the appeal of their programs in an increasingly competitive niche cable environment, as well as to secure upscale audiences for advertisers. The article examines a range of HGTV and Food Network programs that utilized lifestyle's logic, including Emeril Live!, Paula's Home Cooking, Barefoot Contessa, Divine Design with Candice Olson, Design on a Dime, and Small Space, Big Style. In such programs, lifestyle became codified in a set of televisual logics that departed from those found on how-to programs: they articulated middle-class fantasies of ordinariness, had an attenuated focus on instruction in favor of the more diffuse and aspirational concept of “inspiration,” and posited small-scale domestic gatherings as the ideal mode of social engagement in a period of diminishing wealth and income security.

Published: April 2015

The clinical spectrum of hypertrophic cardiomyopathy (HCM) is complex and includes a variety of phenotypes, which leads to different types of manifestations. Although most of the patients are asymptomatic, a significant proportion of them will develop symptoms or risk of arrhythmias and sudden cardiac death (SCD). Therefore, the objectives of HCM diagnosis and management are to relieve the patients’ symptoms (chest pain, heart failure, syncope, palpitations, etc.), prevent disease progression and major cardiovascular complications and SCD. The heterogeneity of HCM patterns, their symptoms and assessment is a challenge for the cardiologist.
Glucocorticoid inhibits cell proliferation in differentiating osteoblasts by microRNA-199a targeting of WNT signaling

Published: April 2015

The inhibition of osteoblast proliferation by glucocorticoids (GCs) is very important in the etiology of GC-induced osteoporosis. The mechanisms of this process are still not fully understood. The results of recent studies have indicated an important role for microRNAs in GC-mediated responses in various cellular processes, including cell proliferation and apoptosis. Therefore, we developed the hypothesis that these regulatory molecules might be involved in GC-decreased osteoblast proliferation. Western blotting, quantitative real-time PCR, cell proliferation assays, and luciferase assays were employed to investigate the role of miRNAs in GC-inhibited osteoblast proliferation. microRNA-199a-5p was significantly increased in osteoblasts treated with dexamethasone (Dex). To delineate the role of microRNA-199a-5p, we silenced and overexpressed microRNA-199a-5p in osteoblasts. We found that overexpressing microRNA-199a-5p remarkably increased the inhibition effect of Dex on osteoblast proliferation, and depleting microRNA-199a-5p significantly attenuated Dex-inhibited osteoblast proliferation. Results of mechanistic studies indicated that microRNA-199a-5p inhibited FZD4 and WNT2 expression through a microRNA-199a-5p binding site within the 3′-UTR of FZD4 and WNT2. The post-transcriptional repression of FZD4 and WNT2 were further confirmed by luciferase reporter assay. These results indicated that microRNA-199a-5p may play a significant role in GC-inhibited osteoblast proliferation by regulating the WNT signaling pathway.

Published: April 2015

Myostatin is a critical negative regulator of skeletal muscle development, and has been reported to be involved in the progression of obesity and diabetes. In the present study, we explored the effects of myostatin on the proliferation and differentiation of 3T3-L1 preadipocytes by using 3-[4,5-dimethylthiazol-2-yl] 2,5-diphenyl tetrazolium bromide spectrophotometry, intracellular triglyceride (TG) assays, and real-time quantitative RT-PCR methods. The results indicated that recombinant myostatin significantly promoted the proliferation of 3T3-L1 preadipocytes and the expression of proliferation-related genes, includingCyclin B2,Cyclin D1,Cyclin E1,Pcna, andc-Myc, and IGF1 levels in the medium of 3T3-L1 were notably upregulated by 35.2, 30.5, 20.5, 33.4, 51.2, and 179% respectively (allP<0.01) in myostatin-treated 3T3-L1 cells. Meanwhile, the intracellular lipid content of myostatin-treated cells was notably reduced as compared with the non-treated cells. Additionally, the mRNA levels ofPparγ,Cebpα,Gpdh,Dgat,Acs1,Atgl, andHslwere significantly downregulated by 22–76% in fully differentiated myostatin-treated adipocytes. Finally, myostatin regulated the mRNA levels and secretion of adipokines, includingAdiponectin,Resistin,Visfatin, and plasminogen activator inhibitor-1 (PAI-1) in 3T3-L1 adipocytes (allP<0.001). Above all, myostatin promoted 3T3-L1 proliferation by increasing the expression of cell-proliferation-related genes and by stimulating IGF1 secretion. Myostatin inhibited 3T3-L1 adipocyte differentiation by suppressingPparγandCebpαexpression, which consequently deceased lipid accumulation in 3T3-L1 cells by inhibiting the expression of critical lipogenic enzymes and by promoting the expression of lipolytic enzymes. Finally, myostatin modulated the expression and secretion of adipokines in fully differentiated 3T3-L1 adipocytes.

Published: April 2015

Large elongated glands occur on Cercideae leaf surfaces. Leaves of Bauhinia (55 taxa, 53 species), Cercis (1 species), Phanera (1 species), Piliostigma (2 species), Schnella (19 species) and Tylosema (1 species) were observed to determine location and relative number of glands. They were only observed on the abaxial leaf surface of 42 Bauhinia taxa. The glands were analyzed by light stereomicroscope and scanning electron microscopy. They are large (up to 270 µm long and 115 µm wide) and multicellular, containing lipophilic substances, probably volatile oils. Presence or absence and density of the glands in species of Bauhinia may be useful to determine species delimitation or distinction among infraspecific taxa. Higher density of glands is more common in species from "cerrado" (a savanna ecosystem) and "caatinga" (a semiarid ecosystem from northeast Brazil) areas. Bauhinia species devoid of foliar glands are frequently from humid forests.

Associadas aos benefícios no solo da semeadura direta, podem ocorrer a formação de gradiente vertical de fertilidade e a de uma camada compactada provocada pelo intenso tráfego de máquinas agrícolas, podendo modificar o crescimento radicular das culturas. O objetivo deste trabalho foi avaliar as doses e formas de aplicação da adubação fosfatada e a compactação do solo pelo tráfego de máquinas nos atributos físicos e no sistema radicular da soja e do milho nas condições da Chapada dos Parecis, MT. O estudo foi realizado em Latossolo Vermelho-Amarelo distrófico argiloso em delineamento em blocos casualizados, no esquema fatorial 2 × 4 × 4 e três repetições, sendo duas formas de adubação fosfatada (a lanço e no sulco), quatro doses de P2O5 (0, 50, 100 e 150 kg ha-1) e quatro níveis de compactação (PT0, PT2, PT4 e PT8 – semeadura direta com compactação induzida por tráfego de trator em zero, duas, quatro e oito passadas, respectivamente). O tráfego de máquinas ocasionou compactação do solo em semeadura direta, aumentando a densidade do solo (Ds) e resistência do solo à penetração (RSP) e reduzindo a macroporosidade e porosidade total, sem efeito da adubação fosfatada. A resposta das espécies à forma de adubação fosfatada foi diferenciada, não apresentando influência no crescimento radicular da soja. No milho, quando fornecida a lanço proporcionou maior área de raízes na camada de 0,00-0,05 m; e, quando no sulco, foram observadas entre as camadas menores diferenças na área radicular.

Este trabalho objetivou avaliar diferentes estruturas da matriz de variâncias e covariâncias residual (Σ), quanto ao ajustamento de dados longitudinais via modelos mistos, em experimentos varietais de cana-de-açúcar. A seleção adequada desta matriz garante a escolha de um modelo mais representativo dos dados. Em cada modelagem, variou-se ainda a suposição associada aos efeitos de tratamentos (variedades), como fixos e aleatórios. Quatro ensaios varietais, conduzidos entre 2005 e 2009, em três localidades do Estado de Goiás, foram considerados. Cada experimento foi delineado em blocos casualizados com três ou quatro repetições. A variável resposta analisada foi toneladas de colmos por hectare (TCH). Para avaliar a qualidade de ajustamento dos modelos, foram utilizados o critério de informação de Akaike (AIC) e o teste da razão de verossimilhanças. Este último foi utilizado apenas para comparar modelos hierárquicos, tomados dois a dois. Constatou-se que as análises pelo modelo univariado clássico de parcelas subdivididas oscilaram entre as piores ou entre aquelas de ajustes apenas medianos. As estruturas da matriz Σ com os melhores ajustamentos variaram entre os ensaios, com destaque para a matriz não-estruturada. Tais resultados revelam que a estrutura de erros independentes, em geral, não se mostra adequada para esse tipo de análise e, também, que não é seguro definir previamente uma estrutura específica de Σ para tais ensaios. Pequenas alterações foram observadas na classificação das estruturas ao se assumirem os efeitos de tratamentos como fixos ou aleatórios; porém, sem efeito importante na classificação das melhores estruturas em cada ensaio.

EVALUATION OF LOGISTIC PERFORMANCE INDEXES OF BRAZIL IN THE INTERNATIONAL TRADE
Authors: FARIA ROSANE NUNES DE , SOUZA CAIO SILVESTRE DE , VIEIRA JOSÉ GERALDO VIDAL
Published: April 2015

The importance of efficient logistics for trade growth is widely acknowledged. Literature has shown that better logistics performance is strongly associated with trade expansion, export diversification, ability to attract foreign direct investments, and economic growth. On the other hand, international trade represents a challenge to logistic operations in transporting and storing products. High logistic costs and low quality of services may be considered obstacles to international trade. This research aims to assess Brazil’s Logistics Performance Index (LPI) in relation to its major competitors in international trade. The international trade data was collected from SECEX and COMTRADE, while the LPI was provided by the World Bank. Statistical techniques such as cluster analysis and multiple comparison tests of means have been applied to analyze the data. After using LPI index for the 39 competitors, it has been observed that Brazil occupies the 26th position in the rank of performers, behind South Africa, Kuwait and Saudi Arabia. The top performers are in general the leading exporters and importers worldwide (Germany, U.S.A., Japan and the Netherlands). Furthermore, they are the strongest competitors of Brazil in international trade. Thus, the competitiveness of Brazilian domestic firms depends crucially on a dynamic and competitive internal logistic environment in order to stand up to these countries. The results also indicate the bureaucracy as a major obstacle to the logistic performance of the country. The dimension Timeliness of Brazil is very close to the High Logistics Performance Group (HLPG) while Customs is very close to the Low Logistics Performance Group (LLPG). Although Brazil has failed in its customs operations, there seems to be more credibility in Brazilian dealings. The main contribution of this paper is to reveal logistical aspects in which Brazil has shown large inefficiencies. The difference among the logistic performance indexs also appears to be relevant to governments to address their new public policies and also to highlight the logistic obstacles of the Brazilian international trade.
REDES SOCIAIS EMPREENDEDORAS PARA OBTENÇÃO DE RECURSOS E LEGITIMAÇÃO ORGANIZACIONAL: ESTUDO DE CASOS MÚLTIPLOS COM EMPREENDEDORES SOCIAIS

Published: April 2015

Também denominadas como redes de relacionamentos, as redes sociais empreendedoras abordam as relações com outras organizações, com grupos de empresas e com pessoas que os ajudam a criar empreendimentos. O objetivo geral deste estudo é analisar como os empreendedores sociais, durante a fase de concepção dos seus negócios, valem-se das suas redes sociais ou de relações para obter recursos e legitimação organizacional. Especificamente, este trabalho pretendeu identificar os laços sociais conforme definição de Granovetter (1973), apontar os recursos mobilizados por meio das redes de relacionamento de acordo com classificação de Brush, Greene e Hart (2001) e verificar os critérios de legitimação das organizações com fins sociais com base na tipologia de Atack (1999). O presente estudo tem abordagem qualitativa, de natureza exploratória e descritiva. Utilizou-se o estudo de casos múltiplos como estratégia de pesquisa. A coleta de evidências foi realizada por meio de entrevistas semiestruturadas com três empreendedores sociais. Os diálogos foram gravados e posteriormente transcritos. O conteúdo das entrevistas foi analisado com a adoção da técnica de análise de conteúdo. Após a análise dos casos, foi possível observar, nas redes de relacionamentos dos empreendedores, tanto laços fracos como fortes. Estes últimos resumiram-se a família, amigos e colegas de profissão. No que diz respeito aos laços fracos, citaram-se empresas públicas, privadas e doadores/colaboradores pessoas físicas. Os laços fortes, em especial, fomentaram praticamente todos os tipos de recursos necessários à concepção dos empreendimentos analisados. Os laços fracos, por sua vez, promoveram uma boa parcela dos recursos físicos necessários às organizações em questão. Foi possível observar também que as redes de relacionamento contribuíram para a legitimação das organizações com fins sociais analisadas. Verificou-se o quanto elas são participativas com relação ao fomento da legitimidade formal-procedimental. Entretanto, os empreendedores poderiam ainda ter potencializado essa fonte de recursos, aproveitando-as melhor no âmbito da legitimação substantivo-proposital, fomentando a promoção de mecanismos para motivar e captar voluntários, desenvolvendo critérios a fim de mensurar a eficácia das atividades promovidas ou ainda aproveitando o capital intelectual das suas redes por meio da promoção do processo coletivo de tomada de decisão.

Published: April 2015

Introduction: valve disease is an important cause of heart failure. There is a direct relationship between valve deterioration and the patient’s inflammatory status and cytokines: interleukin-6, interleukin-1, tumor necrosis factor, and C-reactive protein, involved in this major state of inflammation. Objective: to report a series of cases of valve replacement, using a bioprosthetic or mechanical valve, and the inflammatory profile of them. Methods: patients older than 18 years and with bioprosthetic or mechanical valve placed for a minimum of 6 months and maximum of 2 years were included. In addition to the demographic characteristics of each patient, inflammatory markers were measured and a comparison was made of echocardiographic results before (based on medical records) and after surgery. A total of 46 patients were enrolled, 23 with mechanical valve and 23 with bioprosthetic valve. Results: of the 46 patients, 20 presented complete data were included, 12 with bioprosthetic and 8 with mechanical valve. There was no difference between types of prosthesis or implant site for the values of inflammatory markers although they were all above reference range. Discussion: patients undergoing aortic mechanical valve implant benefited more than those undergoing bioprosthetic implant and both with much better results than those of valve replacements performed on mitral valve. In short, there was no difference in relation to inflammatory biomarkers.

Authors: Price Anthony
Published: April 2015

To develop electrical energy storage projects, it is necessary to understand the commercial and regulatory structure of the power industry and to ensure that the impact of regulation and legislation is taken into account in the planning, construction and operation of the project. Electrical energy storage can be used by generators, including renewable generators of electricity, transmission and distribution operators, suppliers and users of electricity. In the UK, there are varying regulations for electricity storage and different market structures for its operation. This briefing note outlines the key issues under consideration in Great Britain and compares this with practices elsewhere.
Is colour change a good measure of a water penetration front?
Authors: Fischer N. , Haerdtl R. , McDonald P. J.
Published: April 2015

GARField nuclear magnetic resonance (NMR) profiling is used to demonstrate that the sharp colour change boundary commonly used to locate the water front in cement and concrete capillary absorption tests is a poor indicator of the true depth of water penetration. Across a range of mortars and concretes, NMR invariably shows a smooth and often near-zero gradient in the degree of saturation at this boundary. Any sharp front that does exist, as might arise from a strong dependence of the effective diffusivity on concentration and a multi-modal pore size distribution on the nanoscale, is always far beyond the colour change line.
