Wolfgang Schnell passed away on 2nd October after an illness which he endured with great courage and lucidity. Wolfgang was one of CERN's pioneers and made numerous significant contributions to the field of accelerator physics and technology throughout his career. After obtaining a degree in physics from the University of Heidelberg, he worked at the Max-Planck Institute, before joining the PS construction team in 1954. When working in the group led by Chris Schmelzer in 1959, he achieved a breakthrough during the running-in of the PS, which suffered from substantial beam loss during acceleration. With the phase-lock feed-back system built by Wolfgang, the beam went immediately to 24 GeV with hardly any losses. He was proud to show later that the electronics of his system had been built inside a coffee tin.

    This paper examines the career of Johann Sebastian Bach (1685-1750) and the role played by Wilhelm His I (who was, with Albert von Haller, a noted pioneer of physiology) in the exhumation of Bach's remains in 1894. His's examination of these remains allowed the sculptor Carl Seffner to produce the celebrated statue of Bach which stands outside the church of St Thomas in Leipzig, where the composer was employed from 1723 until his death. Modern forensic techniques have recently enabled Bach's image to be reconstructed in even more spectacular detail. © 2014 Royal Australasian College of Surgeons.

    Wolfgang Kummer was not only a great theorist but also a man with a noble spirit and extensive education, based on a fascinating long-term Austrian cultural tradition. As an experimentalist I am not sufficiently knowledgeable to evaluate his contributions to theoretical physics - this will certainly be done by more competent scientists. Nevertheless I admired him for not only being attached to fundamental and abstract problems like quantum field theory, quantum gravity or black holes, but for his interest in down to earth questions like electron-proton scattering or the toponium mass. I got to know Wolfgang Kummer very well and appreciate his human qualities during his long attachment to CERN, in particular when he served as president of the CERN Council, the highest decision taking authority of this international research centre, from 1985 to 1987 falling into my term as Director-General…

  5. Are the alleged remains of Johann Sebastian Bach authentic?

    A skeleton alleged to be that of Johann Sebastian Bach (1685-1750) was exhumed from a graveyard in Leipzig, Germany, in 1894, but its authenticity is not established. In 1895, anatomist Wilhelm His concluded from his examination of the skeleton and reconstruction of the face that it most likely belonged to Bach. In 1949, surgeon Wolfgang Rosenthal noticed exostoses on the skeleton and on x-rays of 11 living organists and proposed a condition, Organistenkrankheit, which he interpreted as evidence that the skeleton was Bach's. However, our critical assessment of the remains analysis raises doubts: the localisation of the grave was dubious, and the methods used by His to reconstruct the face are controversial. Also, our study of the pelvic x-rays of 12 living professional organists failed to find evidence for the existence of Organistenkrankheit. We believe it is unlikely that the skeleton is that of Bach; techniques such as DNA analysis might help resolve the question but, to date, church authorities have not approved their use on the skeleton.

    Bach1 is a transcriptional repressor of heme oxygenase-1 (HO-1, a.k.a. HSP-32), which is an inducible enzyme and has anti-oxidation/anti-inflammatory properties shown in various models of organ injuries. Since oxidative stress plays a pivotal role in the pathogenesis of nonalcoholic steatohepatitis (NASH), HO-1 induction would be expected to prevent the development of NASH. In this study, we investigated the influence of Bach1 ablation in mice on the progression of NASH in methionine-choline deficient (MCD) diet model. Bach1 ablation resulted in significant induction of HO-1 mRNA and its activity in the liver. When fed MCD diet, Bach1(-/-) mice exhibited negligible hepatic steatosis compared to pronounced steatohepatitis in wild type mice with 6-fold increase in hepatic triglyceride content. Whereas feeding of MCD diet decreased mRNA expressions of peroxisome proliferator-activated receptor (PPAR) α and microsomal triglyceride transfer protein (MTP) in wild type mice, there were no change in Bach1(-/-) mice. In addition, hepatic concentration of malondialdehyde (MDA), a biomarker for oxidative stress as well as plasma alanine aminotransferase (ALT) was significantly lower in Bach1(-/-) mice. These findings suggest that Bach1 ablation exerts hepatoprotective effect against steatohepatitis presumably via HO-1 induction and may be a potential therapeutic target.

    To study whether Johan Sebastian Bach music has a lowering effect on resting energy expenditure (REE) similar to that of Wolfgang Amadeus Mozart music. Prospective, randomized clinical trial with cross-over in 12 healthy, appropriate weights for gestational age (GA), gavage fed, metabolically stable, preterm infants. Infants were randomized to a 30-min period of either Mozart or Bach music or no music over 3 consecutive days. REE was measured every minute by indirect calorimetry. Three REE measurements were performed in each of 12 infants at age 20±15.8 days. Mean GA was 30.17±2.44 weeks and mean birthweight was 1246±239 g. REE was similar during the first 10-min of all three randomization periods. During the next 10-min period, infants exposed to music by Mozart had a trend toward lower REE than when not exposed to music. This trend became significant during the third 10-min period. In contrast, music by Bach or no music did not affect significantly REE during the whole study. On average, the effect size of Mozart music upon REE was a reduction of 7.7% from baseline. Mozart music significantly lowers REE in preterm infants, whereas Bach music has no similar effect. We speculate that 'Mozart effect' must be taken into account when incorporating music in the therapy of preterm infants, as not all types of music may have similar effects upon REE and growth.

    Limited vision seems to have been Johann Sebastian Bach's (1685-1750) only physical problem. Myopia seems the most likely cause and he probably developed cataracts later in life. In addition to the cataracts, his worsening vision may have been due in part to some other eye problem. In 1750 Bach's

    Johann Sebastian Bach (1685-1750) was one of the greatest composers of all time. Apart from performing as a brilliant organist, he composed over 1.100 works in almost every musical genre. He was known as a hardworking, deeply Christian person, who had to support his family of 20 children and many students staying at his home. At the age of 64 years, his vision started to decline. Old biographies claim that it was the result of overstressing his vision in poor illumination. By persuasion of his friends, he had his both eyes operated by a travelling British eye surgeon. A cataract couching was performed. After surgery, Bach was totally blind and unable to play an organ, compose or direct choirs and orchestras. He was confined to bed and suffering from immense pain of the eyes and the body. He died <4 months after surgery. In this paper, as the plausible diagnosis, intractable glaucoma because of pupillary block or secondary to phacoanaphylactic endophthalmitis is suggested. © 2012 The Author.

    Wolfgang Pauli (1900-1958) is named by his colleagues in the same breath with Isaac Newton and Albert Einstein, who named Pauli his ''mental son''. The history of science had neglected Pauli for a long time. The reason for this may be found in Pauli's attempts to capture the role of the unconscious in physics and the meaning of dreams in the creation of scientific pictures of the world. For Pauli a scientific method consisted in activating the unconscious and hoping that it would start up that specific type of ''painting viewing'' from which the terms can arise by which we express our understanding

    Thomas Schwencke (1694-1767) was Professor of Anatomy and Surgery and Lecturer in Obstetrics at the Surgical School in The Hague, the Netherlands. In 1743 he published the very first textbook on haematology. Furthermore, he described his observations on the variolation of smallpox, and published the design of a new obstetric instrument. Schwencke was physician of the city of The Hague and also physician at the court of the princes van Nassau-Weilburg. In 1765 Princess Caroline of Nassau-Weilburg invited the young Wolfgang Amadeus Mozart to perform concerts. During his Dutch tour the young Mozart fell seriously ill, probably from typhoid fever. At the request of the court Mozart was seen for a second opinion and thereafter successfully treated by Schwencke. Mozart could continue his concert tour and Schwencke's reputation as Mozart's physician was established.

  19. Rigidity of generalized Bach-flat vacuum static spaces

    Yun, Gabjin; Hwang, Seungsu

    2017-11-01

    In this paper, we study the structure of generalized Bach-flat vacuum static spaces. Generalized Bach-flat metrics are considered as extensions of both Einstein and Bach-flat metrics. First, we prove that a compact Riemannian n-manifold with n ≥ 4 which is a generalized Bach-flat vacuum static space is Einstein. A generalized Bach-flat vacuum static space with the potential function f having compact level sets is either Ricci-flat or a warped product with zero scalar curvature when n ≥ 5, and when n = 4, it is Einstein if f has its minimum. Secondly, we consider critical metrics for another quadratic curvature functional involving the Ricci tensor, and prove similar results. Lastly, by applying the technique developed above, we prove Besse conjecture when the manifold is generalized Bach-flat.

  20. USING BACH FLOWER IN HOLISTIC PSYCHOTHERAPY

    Full Text Available This is a narrative review from scientific literature that aimed to describe concepts and approaches for indications of the therapeutic use of Bach flower remedies in holistic psychotherapy. The review was developed in February 2016 from books, official documents and articles indexed in Lilacs and Scielo databases. Bach flower remedies is a therapeutic method that aims to restore the balance of human being, restoring its vital energy through holistic care. Because the flower essences act on psychic and emotional dimension of individual, when employed in holistic psychotherapy can provide greater autonomy, self-care and effectiveness compared to other alternative methods. The literature indicated that flower essence therapy is a safe practice and can be used in a complementary to health care, but should be performed by qualified professionals. It has also shown to be a promising and important area for nursing professional, but it still requires greater investment in research in the area to support the practice.

    We show that a (2n + 1)-dimensional Sasakian manifold (M, g) with a purely transversal Bach tensor has constant scalar curvature ≥2 n (2 n +1 ) , equality holding if and only if (M, g) is Einstein. For dimension 3, M is locally isometric to the unit sphere S3. For dimension 5, if in addition (M, g) is complete, then it has positive Ricci curvature and is compact with finite fundamental group π1(M).

    2006-04-01

    The death of Wolfgang Amadeus Mozart was mysterious from the very first day, and cause of wildest speculation and adventurous assertions. Over the last 100 years, medical science has investigated the physical sufferings and the mysterious death of Mozart with increasing intensity. By means of letters from his father Leopold, his sister "Nannerl", himself and reports from his physicians and contemporaries, we would like to create a medical pathography. The rumour that Mozart was poisoned appeared soon after his early death at the age of 35 on December 5th 1791, and was kept up persistently. Accused were the physician van Swieten, Mozart's freemason's loge and the royal band master Salieri. Mozart, however, died due to chronic kidney disease and ultimately due to uraemia. Once the renal damage has reached a certain point, a minimum of additional stress leads to decompensation. This catastrophe occurs typically within the fourth decade of life. When listening to Mozart's music, we should remember that this apparently happy person was actually a premature adult robbed of his childhood, whose short life was an endless chain of indisposition, over fatigue, misery, concern and illness.

  3. [Health and death of Wolfgang Amadeus Mozart].

    Zegers, R H C

    2002-12-21

    Not much is known about the medical history and cause of death of the composer Wolfgang Amadeus Mozart (1756-1791). Contrary to popular opinion, Mozart was not an exceptionally ill child and as an adult he generally enjoyed good health. At the age of 9 years he experienced a life-threatening illness, which was probably typhoid fever. On the left-hand side he had what has since become known as 'Mozart's ear', a pinna with under-development of the anthelical fold. His psychological condition gives rise to the notion that he was not exceptional, but that he responded to the events in his life in a normal manner. His terminal illness was characterised by edema of hands and feet, without any associated dyspnoea being described. The medical treatment was aggressive: enema, bloodletting on several occasions and treatment with a laxative substance. He was burried in an anonymous grave. The skull that was later ascribed to him was not his own, as no element of the denture fits with the tooth abscess he was known to have experienced. An overdose of mercury during the treatment of syphilis seems to be unlikely, as equally Henoch-Schönlein-purpura and the consequences of acute rheumatism. Trichinosis is a recent hypothesis which fits the terminal symptoms and the fact that Mozart was fond of pork. The diagnosis of his physician Closset was 'hitsiges Frieselfieber', which was possibly caused by one of the many infectious diseases prevalent at that time.

    The Boston Area Community Health (BACH) Survey is a community-based, random sample, epidemiologic cohort of n = 5502 Boston (MA) residents. The baseline BACH Survey (2002-05) was designed to explore the mechanisms conferring increased health risks on minority populations with a particular focus on urologic signs/symptoms and type 2 diabetes. To this end, the cohort was designed to include adequate numbers of US racial/ethnic minorities (Black, Hispanic, White), both men and women, across a broad age of distribution. Follow-up surveys were conducted ∼5 (BACH II, 2008) and 7 (BACH III, 2010) years later, which allows for both within- and between-person comparisons over time. The BACH Survey's measures were designed to cover the following seven broad categories: socio-demographics, health care access/utilization, lifestyles, psychosocial factors, health status, physical measures and biochemical parameters. The breadth of measures has allowed BACH researchers to identify disparities and quantify contributions to social disparities in a number of health conditions including urologic conditions (e.g. nocturia, lower urinary tract symptoms, prostatitis), type 2 diabetes, obesity, bone mineral content and density, and physical function. BACH I data are available through the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Central Repositories (www.niddkrepository.org).

    BTB and CNC homology (BACH) proteins are transcriptional repressors of the basic region leucine zipper (bZIP) transcription factor family. Recent studies indicate widespread roles of BACH proteins in controlling the development and function of the innate and adaptive immune systems, including the differentiation of effector and memory cells of the B and T cell lineages, CD4 + regulatory T cells and macrophages. Here, we emphasize similarities at a molecular level in the cell-type-specific activities of BACH factors, proposing that competitive interactions of BACH proteins with transcriptional activators of the bZIP family form a common mechanistic theme underlying their diverse actions. The findings contribute to a general understanding of how transcriptional repressors shape lineage commitment and cell-type-specific functions through repression of alternative lineage programmes.

    Full Text Available Abstract Background BACH1 (BRCA1-associated C-terminal helicase 1; also known as BRCA1-interacting protein 1, BRIP1 is a helicase protein that interacts in vivo with BRCA1, the protein product of one of the major genes for hereditary predisposition to breast cancer. Previously, two BACH1 germ line missense mutations have been identified in early-onset breast cancer patients with and without family history of breast and ovarian cancer. In this study, we aimed to evaluate whether there are BACH1 genetic variants that contribute to breast cancer risk in Finland. Methods The BACH1 gene was screened for germ line alterations among probands from 43 Finnish BRCA1/2 negative breast cancer families. Recently, one of the observed common variants, Ser-allele of the Ser919Pro polymorphism, was suggested to associate with an increased breast cancer risk, and was here evaluated in an independent, large series of 888 unselected breast cancer patients and in 736 healthy controls. Results Six BACH1 germ line alterations were observed in the mutation analysis, but none of these were found to associate with the cancer phenotype. The Val193Ile variant that was seen in only one family was further screened in an independent series of 346 familial breast cancer cases and 183 healthy controls, but no additional carriers were observed. Individuals with the BACH1 Ser919-allele were not found to have an increased breast cancer risk when the Pro/Ser heterozygotes (OR 0.90; 95% CI 0.70–1.16; p = 0.427 or Ser/Ser homozygotes (OR 1.02; 95% CI 0.76–1.35; p = 0.91 were compared to Pro/Pro homozygotes, and there was no association of the variant with any breast tumor characteristics, age at cancer diagnosis, family history of cancer, or survival. Conclusion Our results suggest that the BACH1 Ser919 is not a breast cancer predisposition allele in the Finnish study population. Together with previous studies, our results also indicate that although some rare germ line variants

Recently, one of the observed common variants, Ser-allele of the Ser919Pro polymorphism, was suggested to associate with an increased breast cancer risk, and was here evaluated in an independent, large series of 888 unselected breast cancer patients and in 736 healthy controls. Six BACH1 germ line alterations were observed in the mutation analysis, but none of these were found to associate with the cancer phenotype. The Val193Ile variant that was seen in only one family was further screened in an independent series of 346 familial breast cancer cases and 183 healthy controls, but no additional carriers were observed. Individuals with the BACH1 Ser919-allele were not found to have an increased breast cancer risk when the Pro/Ser heterozygotes (OR 0.90; 95% CI 0.70–1.16; p = 0.427) or Ser/Ser homozygotes (OR 1.02; 95% CI 0.76–1.35; p = 0.91) were compared to Pro/Pro homozygotes, and there was no association of the variant with any breast tumor characteristics, age at cancer diagnosis, family history of cancer, or survival. Our results suggest that the BACH1 Ser919 is not a breast cancer predisposition allele in the Finnish study population. Together with previous studies, our results also indicate that although some rare germ line variants in BACH1 may contribute to breast cancer development, the

    Full Text Available Passions are exceptionally important in the works of Johann Sebastian Bach. His passion compositions are based particularly on Luther’s reformation, chiefly on developmental tendency which is based on the works of Johann Walter, Hans Leo Hassler and Michael Praetorius. The most significant forerunner of J. S. Bach was Heinrich Schütz. J. S. Bach’s textual aspect is aimed at the model of passion oratorio the main representative of which was a librettist Heinrich Brockes who worked in Hamburg. The interesting fact is that before the arrival of J. S. Bach, in 1723, there was no long tradition of passions in Leipzig. They were performed there in 1721 for the first time. J. S. Bach is demonstrably the author of the two passions: St Matthew Passion BWV 244 and St John Passion BWV 245. The authorship of Johann Sebastian Bach in St. Lukas Passion BWV 246 is strongly called into question and from St Mark Passion BWV 24 only the text was preserved.

    Let (Mn,g) be a complete noncompact Bach-flat n-manifold with the positive Yamabe constant and constant scalar curvature. Assume that the L2-norm of the trace-free Riemannian curvature tensor R∘m is finite. In this paper, we prove that (Mn,g) is a constant curvature space if the L-norm of R∘m is sufficiently small. Moreover, we get a gap theorem for (Mn,g) with positive scalar curvature. This can be viewed as a generalization of our earlier results of 4-dimensional Bach-flat manifolds with constant scalar curvature R≥0 [Y.W. Chu, A rigidity theorem for complete noncompact Bach-flat manifolds, J. Geom. Phys. 61 (2011) 516-521]. Furthermore, when n>9, we derive a rigidity result for R<0.

    Conformal gravity theories are defined by field equations that determine only the conformal structure of the spacetime manifold. The Bach equations represent an early example of such a theory, we present them here in component form in terms of spin- and boost-weighted spin-coefficients using the compacted spin-coefficient formalism. These equations can be used as an efficient alternative to the standard tensor form. As a simple application we solve the Bach equations for pp-wave and static spherically symmetric spacetimes.

    The author examines the generalisation of the Bach-Lanczos Lagrangian in matrix relativity where it is no longer a topological invariant, and find that for certain structures of the matrix affine connection a Yang-Mills type Lagrangian is obtained. Thus the possibility is considered of interpreting non-Abelian gauge fields as arising from an otherwise topological invariant. (author)

    The goal of this paper is to express the Bach tensor of a four-dimensional conformal geometry of an arbitrary signature by the Cartan normal conformal (CNC) connection. We show that the Bach tensor can be identified with the Yang-Mills current of the connection. It follows from that result that a conformal geometry whose CNC connection is reducible in an appropriate way has a degenerate Bach tensor. As an example we study the case of a CNC connection which admits a twisting covariantly constant twistor field. This class of conformal geometries of this property is known as given by the Fefferman metric tensors. We use our result to calculate the Bach tensor of an arbitrary Fefferman metric and show that it is proportional to the tensorial square of the four-fold eigenvector of the Weyl tensor. Finally, we solve the Yang-Mills equations imposed on the CNC connection for all the homogeneous Fefferman metrics. The only solution is the Nurowski-Plebanski metric

    Bach2 is a transcription factor which represses its target genes and plays important roles in the differentiation of B and T lymphoid cells. Bach2-deficient (KO) mice develop severe pulmonary alveolar proteinosis, which is associated with increased numbers of granulocytes and T cells. Bach2 is essential for the regulation of T cells, but its role in the regulation of granulocytes is not clear. Here, we observed increased numbers of eosinophils but not neutrophils in the bone marrow, spleen, peripheral blood, and bronchoalveolar lavage fluids of Bach2 KO mice compared with those of wild-type (WT) mice. Upon co-transplantation of the bone marrow cells from CD45.2 Bach2 KO and CD45.1/CD45.2 double-positive WT mice to irradiated WT CD45.1/CD45.2 mice, the reconstituted numbers of eosinophils were similar between Bach2 KO and WT cells. These results showed that the deficiency of Bach2 in eosinophils did not directly drive the differentiation of eosinophils. To investigate the effect of Bach2 KO CD4 + T cells upon eosinophils, we analyzed Rag2/Bach2-double deficient (dKO) mice which lack lymphocytes including CD4 + T cells. Rag2/Bach2 dKO mice did not show any increase in the numbers of eosinophils. Importantly, Bach2 KO mice showed an increase of interleukin-5 (Il-5) in the sera compared with WT mice. These results suggest that up-regulated functions of CD4 + T cells including secretion of Il-5 resulted in proliferation and/or migration to peripheral tissues of eosinophils in Bach2 KO mice. We propose that Bach2 controls homeostasis of eosinophils via restricting the production of Il-5 in CD4 + T cells.

At the end of the eighteenth century it became the main format of orchestralmusic. However, it became prominent at the time of Beethoven. Symphony is a great and ambitious piece of musicsince it is played for 20-45 minutes in length, containing an expansion of tone colors and dynamics of classicalorchestra. It has been known that classical symphony usually consists of four parts inciting broader emotion bythe created tempo and nuance. Mozart’s three last symphonies are Mozart’s masterpieces and Symphony No. 40,for example, contains connotations of romantic signs ignored by his predecessors. Although Symphony No. 40employs minor tones, it is not sad but cheerful, playful, passionful, and dramatic. The fi rst part of the Symphonyuses Allegro Sonata format which consists of three parts, namely exposition, development and recapitulation.

    2013-08-01

    In this paper, we study a coupled system of equations on oriented compact 4-manifolds which we call the Bach-Merkulov equations. These equations can be thought of as the conformally invariant version of the classical Einstein-Maxwell equations. Inspired by the work of C. LeBrun on Einstein-Maxwell equations on compact Kähler surfaces, we give a variational characterization of solutions to Bach-Merkulov equations as critical points of the Weyl functional. We also show that extremal Kähler metrics are solutions to these equations, although, contrary to the Einstein-Maxwell analogue, they are not necessarily minimizers of the Weyl functional. We illustrate this phenomenon by studying the Calabi action on Hirzebruch surfaces.

    Bach1 and Bach2 are evolutionarily related members of the BTB-basic region leucine zipper transcription factor family. We found that Bach2 downregulates cell proliferation of N1E-115 cells and negatively affects their potential to differentiate. Nuclear localization of the cyclin-dependent kinase inhibitor p21 is known to arrest cell cycle progression, and cytoplasmic p21 has been shown to promote neuronal differentiation of N1E-115 cells. We found that ectopic Bach2 causes upregulation of p21 expression in the nucleus and in the cytoplasm in undifferentiated N1E-115 cells. In differentiated cells, Bach2 specifically triggers upregulation of cytoplasmic p21. Our data suggest that Bach2 expression could represent a switch during the process of neuronal differentiation. Bach2 is not expressed in neuronal precursor cells. It would have negative effects on proliferation and differentiation of these cells. In differentiated neuronal cells Bach2 expression is upregulated, which could allow Bach2 to function as a gatekeeper of the differentiated status

    Johann Sebastian Bach was born on 1685 in Eisenach. By the time he turned 10, Bach found himself an orphan after the death of both of his parents. After working in Weimar, Arnstadt, Mühlhausen, and Köthen Bach signed a contract to become the new organist and teacher at St. Thomas Church Leipzig in 1723 and stayed there until his death. In 1749, Bach tried to fix his failing sight by having surgery the following year, but the operation ended up leaving him completely blind. Few months later, Bach suffered a stroke. He died in Leipzig on July 28, 1750. In recent years, there were some questions whether music of different styles can directly alter cardiovascular parameters, particularly by using Bach's music. In some studies it has been shown that cardiovascular parameters (blood pressure, heart rate) are influenced by music. Listening to classic music (Bach) leads to positive erffects, also music by Italian composters. In contrast, "modern" music, vocal music or songs had no positive effects on cardiovascular parameters. In addition, positive effects on cardiovascular parameters and behavioural patters have been shown in an animal study recently, by Bach's music. Recent studies showed clearly that music influences cardiovascular parameters. It is obvious that classical music (Bach) has benefitial effects, both in humans and in animals. Therefore, the music of the "Thomaskantor" will improve both, quality of life and cardiovascular health. © Georg Thieme Verlag KG Stuttgart · New York.

  8. Dynamic changes in Bach1 expression in the kidney of rhabdomyolysis-associated acute kidney injury.

    Directory of Open Access Journals (Sweden)

    Masakazu Yamaoka

    Full Text Available Free heme, a pro-oxidant released from myoglobin, is thought to contribute to the pathogenesis of rhabdomyolysis-associated acute kidney injury (RM-AKI, because renal overexpression of heme oxygenase-1 (HO-1, the rate-limiting enzyme in heme catabolism, confers protection against RM-AKI. BTB and CNC homology 1 (Bach1 is a heme-responsive transcription factor that represses HO-1. Here, we examined the changes with time in the gene expression of Bach1, HO-1, and δ-aminolevulinate synthase (ALAS1, a heme biosynthetic enzyme in the rat kidney using an RM-AKI model induced by the injection of 50% glycerol (10 mL/kg body weight into bilateral limbs. We also examined the protein expression of Bach1 in the nucleus and cytosol, and HO-1 in the rat kidney. Glycerol treatment induced significant elevation of serum creatinine kinase and aspartate aminotransferase levels followed by the marked elevation of serum blood urea nitrogen and creatinine levels, which caused serious damage to renal tubules. Following glycerol treatment, HO-1 mRNA and protein levels were significantly up-regulated, while ALAS1 mRNA expression was down-regulated, suggesting an increase in the free renal heme concentration. The Bach1 mRNA level was drastically increased 3 h after glycerol treatment, and the increased level was maintained for 12 h. Nuclear Bach1 protein levels were significantly decreased 3 h after treatment. Conversely, cytosolic Bach1 protein levels abruptly increased after 6 h. In conclusion, we demonstrate the dynamic changes in Bach1 expression in a rat model of RM-AKI. Our findings suggest that the increase in Bach1 mRNA and cytosolic Bach1 protein expression may reflect de novo Bach1 protein synthesis to compensate for the depletion of nuclear Bach1 protein caused by the induction of HO-1 by free heme.

    The early and unexpected death of Wolfgang Amadeus Mozart (Salzburg, 1756 - Vienna, 1791) was a mystery from the very first day and the subject of wildest speculations and adventurous assertions. Over the last 100 years, medical science has investigated the physical sufferings and the mysterious death of Mozart with increasing intensity. The aim of this article was to recreate Mozart's pathography relying on the his correspondence with father Leopold and sister Nannerl and on reports from his physicians and contemporaries. The rumour that Mozart was poisoned followed shortly after his death on 5 December 1791, at the age of 35, and has survived to this day. The alleged culprits were his physician van Swieten, Mozart's freemasons lodge, and the Imperial Chapel Master Salieri. Mozart however died of chronic kidney disease and ultimately of uraemia. If kidney damage reaches a critical point, even a minimum additional stress can lead to its failure. This usually occurs in the fourth decade of life. Next time we listen to Mozart, we should remember that this apparently happy person was actually a precocious boy, ripped of his childhood, whose short life was an endless chain of complaints, fatigue, misery, concern, and malady.

    The nervous system works like a great orchestra. Specifically, the music of Mozart with its "Mozart effect" is appropriate to use in neurosurgery. We investigated the relationship between Mozart's music and neurosurgery. We used digital catalogs like "PubMed" and the libraries of universities. Key words were "Wolfgang Amadeus Mozart" and "neurosurgery and music." In the first half of the 20th century, performing neurosurgery on some musicians, such as Maurice Ravel, Josef Hassid, and George Gershwin, resulted in a fatal outcome. The cause of this is probably that neurosurgery had not been developed yet in the first half of the 20th century. In the past 3 decades, the neurosurgical operations of musicians show that musicians have rich associations among auditory, somatic, and sensorial systems. It is clear that we have much to learn from studies about music and brain function that derive from our surgical experiences with patients. The neuronal plasticity of musicians' brains may be different from that of nonmusicians' brains. Musicians with enhanced motor skills have greater capacity for plasticity because of enriched interhemispheric connections. Listening to music and the effect of Mozart in neurosurgical practice, intensive care, or rehabilitation were documented in many studies. As authors, we mean something different: Its effectiveness should be studied. We concluded that in current neurosurgical practice, Mozart has an effect. More research and clinical studies are needed.

    The early death of the composer Wolfgang Amadeus Mozart on 5 December 1791 has fascinated the world for more than 2 centuries. It has been suggested that his final illness was caused by poisoning, renal failure, Henoch-Schönlein purpura, trichinosis, and many other conditions. The official daily register of deaths in Mozart's Vienna was evaluated to provide an epidemiologic framework into which the observations of contemporary witnesses of his death can be integrated. All recorded deaths in Vienna during November and December 1791 and January 1792 were analyzed, together with the corresponding periods in 1790 to 1791 and 1792 to 1793. The deaths of 5011 adults (3442 men, 1569 women) were recorded over these periods. The mean ages of death were 45.5 years (SD, 18.5) for men and 54.5 years (SD, 19.9) for women. Tuberculosis and related conditions accounted for the highest number of deaths; cachexia and malnutrition ranked second, and edema was the third most common cause. According to eyewitness accounts, the hallmark of Mozart's final disease was severe edema. Deaths from edema were markedly increased among younger men in the weeks surrounding Mozart's death compared with the previous and following years. This minor epidemic may have originated in the military hospital. Our analysis is consistent with Mozart's last illness and death being due to a streptococcal infection leading to an acute nephritic syndrome caused by poststreptococcal glomerulonephritis. Scarlet fever, which represents the same underlying disease from an etiologic perspective, is a less likely possibility.

    2015-12-01

    Full Text Available This paper discusses de Clercq’s (2015 contribution to our understanding of the relationship between scale degree and cadence type within Bach chorales from the perspective of style and probability. De Clercq is applauded for the diligence of this research and for attempting to synthesize findings into a practical, working model of benefit to music-theory students and educators. A literal interpretation of a premise underpinning his model—that more common musical events are more indicative of a style—is, however, found to be inconsistent. A test is described in which university students enrolled in a second-level harmony class were presented with pairs of cadences. Cadences were manipulated in various ways, primarily to investigate whether the inclusion of certain figurations would result in a perfect-authentic cadence, the most ubiquitous cadence within Bach chorales, being considered less stylistic than a never-occurring cadence. This proved to be the case, demonstrating the importance of figuration over scale degree and cadence for the accomplishment of style. De Clercq’s model is further discussed with respect to probabilistic models of music and in relation to proscriptive approaches to teaching harmony.

    Leopold Mozart (1719-1787), father of Wolfgang Amadé, had profound medical knowledge and was a passionate medical dilettante. As long as the young Mozart lived with his father and travelled on his concert tours with him, Leopold cared for his son in medical matters. Doctors were only consulted occasionally. In the extensive correspondence of Mozart's father drugs and treatments used for Wolfgang Amadé are reported in detail. This represents a reliable description of the pharmacological therapies of the late 18th century. The mentioned drugs are, as far as possible, viewed from todays medical perspective.

    The archival collection of the Lithuanian Academy of Sciences in Vilnius (Wilno) contains many manuscripts relating to the scientific work of Jan Fryderyk Wolfgang (1776-1859), professor of pharmacy and pharmacology of the Wilno University in the years 1807-1831, the founder and main figure in the Wilno pharmacognostic school, a botanist with substantial achievements in wide-ranging research on the flora of the Wilno region, as well as a historian of pharmacy. The most interesting of the manuscripts include Wolfgang's Autobiografia [Autobiography], written in 1850, and a list of his publications covering a total of 57 items (including some that have hitherto remained unknown), a work entitled Historya Farmakologii i Farmacyi [History of pharmacology and pharmacy], and a particularly valuable manuscript (666 + 12 sheets) entitled Farmakologiia [Pharmacology]. Worth mentioning are also two catalogues of books from Wolfgang's library: one compiled by Wolfgang himself (37 sheets) and the other by Adam Ferdynand Adamowicz. The content of the autobiography manuscript is contained on five sheets. The author of the present article analyzes the document, comparing the information contained in it with the biographies of J. F. Wolfgang that hhave been published so far (these being primarily the biography by Dominik Cezary ChodYko, published in 1863, and that by Witold W3odzimierz G3owacki of 1960). The text of the autobiography is quoted in full, together with numerous comments. The analysis of the manuscript as well as the biographical data contained in the above-mentioned biographies indicate that Wolfgang had great achievements as a scientist (in both research and organizational work), as a champion of public causes and as an educator of a generation of botanists-pharmacognostics. It also transpires from the autobiography, as well as from the research by historians, that he was a very good and trustful person, who readily granted access to his research to his collaborators

    The transcription repressor Bach2 has been proposed as a regulator of T cell quiescence, but the underlying mechanism is not fully understood. Given the importance of interleukin-2 in T cell activation, we investigated whether Bach2 is a component of the network of factors that regulates interleukin-2 expression. In primary and transformed CD4+ T cells, Bach2 overexpression counteracted T cell receptor/CD28- or PMA/ionomycin-driven induction of interleukin-2 expression, and silencing of Bach2...

    The authors evaluated the results of treating hyperthyroidism with 131 I. Patient selection for tre treatment is based on clinical features and laboratory test results such as thyroid uptake, scintigraphy and RIA determinations of thyroid hormones. The average dose is 6.2±1.1 m Ci (that is 233.1±40.7 MBq). The average number of doses is 1.3 for one patient. The results are as follows: - Euthyroid status after 4 years follow-up from the 1 31 I dose administration: 72.3 - Persistent or recurrent hyperthyroidism: 20 %. - Hypothyroid complication appears 6 years after the administration of 1 31 I dose: 14 %. So the cumulative hypothyroid rate is: 2.3 % per year. - Serious complications were not observed in any patient. Hyperthyroidism is a common health problem in Vietnam (1). In the past, only antithyroid drugs and surgery were used. 131 I was first introduced to Vietnam in the Nuclear Medicine Department in Bach Mai in 1971 and thereafter widely applied in the country.

  10. ALT-I pump limiter experiments

    Results from the ALT-I pump limiter experiments in TEXTOR are presented. ALT-I has demonstrated control of the plasma density in a high recycling tokamak by pumping up to 15% of the core efflux. The closed pump limiter designs with restricted entrance geometries to reduce the backflow of neutral gas to the plasma remove over 50% of the ion flux incident on the collection slot. Up to 80% of the entrance ion flux is removed when the edge electron temperature is less than 10 eV and plasma-neutral gas interactions are minimized inside the limiter. Results from a 3-D Monte Carlo neutral gas transport code agree closely with these experimental results. The compound curvature of the head is found to distribute the heat over the surface as predicted in the original designs. Impurity removal experiments demonstrate that significant helium exhaust can be achieved with a pump limiter. During ohmic heating in TEXTOR, the energy and particle confinement times are proportional to the line averaged core density. With ICRH auxiliary heating, tau/sub E/ follow L-mode scaling independent of particle removal by the pump limiter. Pump limiter operation does not directly modify the SOL plasma density and electron temperature, but controls the core plasma density by changing the global recycling at the boundary. The global particle confinement, the particle flux to the limiter, and the edge electron temperature follow the changes in the core density and auxiliary heating power. 25 refs

    Intervertebral disc degeneration is considered to be a major feature of low back pain. Furthermore, oxidative stress has been shown to be an important factor in degenerative diseases such as osteoarthritis and is considered a cause of intervertebral disc degeneration. The purpose of this study was to clarify the correlation between oxidative stress and intervertebral disc degeneration using Broad complex-Tramtrack-Bric-a-brac and cap'n'collar homology 1 deficient (Bach 1-/-) mice which highly express heme oxygenase-1 (HO-1). HO-1 protects cells from oxidative stress. Caudal discs of 12-week-old and 1-year-old mice were evaluated as age-related models. Each group and period, 5 mice (a total of 20 mice, a total of 20 discs) were evaluated as age-related model. C9-C10 caudal discs in 12-week-old Bach 1-/- and wild-type mice were punctured using a 29-gauge needle as annulus puncture model. Each group and period, 5 mice (a total of 60 mice, a total of 60 discs) were evaluated. The progress of disc degeneration was evaluated at pre-puncture, 1, 2, 4, 8 and 12 weeks post-puncture. Radiographic, histologic and immunohistologic analysis were performed to compare between Bach 1-/- and wild-type mice. In the age-related model, there were no significant differences between Bach 1-/- and wild-type mice radiologically and histologically. However, in the annulus puncture model, histological scoring revealed significant difference at 8 and 12 weeks post-puncture. The number of HO-1 positive cells was significantly greater in Bach 1-/- mice at every period. The apoptosis rate was significantly lower at 1 and 2 weeks post-puncture in Bach 1-/- mice. Oxidative stress prevention may avoid the degenerative process of the intervertebral disc after puncture, reducing the number of apoptosis cells. High HO-1 expression may also inhibit oxidative stress and delay the process of intervertebral disc degeneration.

  14. Spherically Symmetric Solutions of the Einstein-Bach Equations and a Consistent Spin-2 Field Theory

    2006-01-01

    We briefly present a relationship between General Relativity coupled to certain spin-0 and spin-2 field theories and higher derivatives metric theories of gravity. In a special case, described by the Einstein-Bach equations, the spin-0 field drops out from the theory and we obtain a consistent spin-two field theory interacting gravitationally, which overcomes a well known inconsistency of the theory for a linear spin-two field coupled to the Einstein's gravity. Then we discuss basic properties of static spherically symmetric solutions of the Einstein-Bach equations. (author)

    This study was aimed to explore the effect of Bach2 on B cells in systemic lupus erythematosus (SLE), as well as the underlying mechanisms. Expression of Bach2, phosphorylated-Bach2 (p-Bach2), Akt, p-Akt and BCR-ABL (p210) in B cells isolated from SLE patients and the healthy persons were assessed by Western blot. Immunofluorescence staining was performed to assess the localization of Bach2 in B cells. Enzyme-linked immunosorbent assay (ELISA) was employed to detect IgG produced by B cells. Cell counting kit-8 (CCK-8) and Annexin-V FITC/PI double staining assay were adopted to evaluate cell proliferation and apoptosis in B cells, respectively. Compared to the healthy controls, Bach2, p-Akt and p210 were significantly decreased, while nuclear translocation of Bach2, IgG, CD40 and CD86 obviously up-regulated in B cells from SLE patients. Bach2 significantly inhibited the proliferation, promoted apoptosis of B cells from SLE patients, whereas BCR-ABL dramatically reversed cell changes induced by Bach2. Besides, BCR-ABL also inhibited nuclear translocation of Bach2 in B cells from SLE patients. Further, LY294002 treatment had no effect on decreased expression of Bach2 induced by BCR-ABL, but significantly eliminated BCR-ABL-induced phosphorylation of Bach2 and restored reduced nuclear translocation of Bach2 induced by BCR-ABL in B cells from SLE. Bach2 may play a suppressive role in B cells from SLE, and BCR-ABL may inhibit the nuclear translocation of Bach2 via serine phosphorylation through the PI3K pathway. Copyright © 2018 Elsevier Inc.

    Nonalcoholic fatty liver disease (NAFLD) is emerging as a component of the metabolic syndrome (MetS); Hispanics being particularly predisposed. Alanine aminotransferase (ALT) is considered a marker of NAFLD. The aim of this study was to determine the prevalence and associations between ALT elevations and MetS in normal-weight, overweight and obese Mexican children and adolescents, since data in Mexico is scarce. Body mass index (BMI), waist circumference (WC), percentage body fat, blood pressure, glucose, lipid profiles, ALT and aspartate aminotransferase (AST) were measured in 236, 6-12yo normal-weight, overweight and obese Mexicans from eight public schools. The results showed that elevated ALT (>40 IU/L) was found in 17.7% of the obese and overweight population, with no gender difference. The prevalence of elevated ALT increased linearly across BMI categories (p = 0.001), from 0.0% for the normal-weight group (95%CI 0.0-€“8.0) to 22.4% for the obese one (95%CI 16.2-€“30.2). AST/ALT ratio obese one. The prevalence of MetS was strongly associated with elevated ALT (p = 0.002), 50% in the elevated ALT group (95%CI 34.1-€“65.9) and 24.1% in the normal ALT one (95%CI 18.1-€“31.3). There was also a strong association between MetS and an AST/ALT ratio obese children. © 2014 Asian Oceanian Association for the Study of Obesity . Published by Elsevier Ltd. All rights reserved.

    The connection between gene regulation and metabolism is an old issue that warrants revisiting in order to understand both normal as well as pathogenic processes in higher eukaryotes. Metabolites affect the gene expression by either binding to transcription factors or serving as donors for post-translational modification, such as that involving acetylation and methylation. The focus of this review is heme, a prosthetic group of proteins that includes hemoglobin and cytochromes. Heme has been shown to bind to several transcription factors, including Bach1 and Bach2, in higher eukaryotes. Heme inhibits the transcriptional repressor activity of Bach1, resulting in the derepression of its target genes, such as globin in erythroid cells and heme oxygenase-1 in diverse cell types. Since Bach2 is important for class switch recombination and somatic hypermutation of immunoglobulin genes as well as regulatory and effector T cell differentiation and the macrophage function, the heme-Bach2 axis may regulate the immune response as a signaling cascade. We discuss future issues regarding the topic of the iron/heme-gene regulation network based on current understanding of the heme-Bach axis, including the concept of "iron immunology" as the synthesis of the iron metabolism and the immune response.

    The regulation of gene expression in response to environmental signals and metabolic imbalances is a key step in maintaining cellular homeostasis. BTB and CNC homology 1 (BACH1) is a heme-binding transcription factor repressing the transcription from a subset of MAF recognition elements at low intracellular heme levels. Upon heme binding, BACH1 is released from the MAF recognition elements, resulting in increased expression of antioxidant response genes. To systematically address the gene regulatory networks involving BACH1, we combined chromatin immunoprecipitation sequencing analysis of BACH1 target genes in HEK 293 cells with knockdown of BACH1 using three independent types of small interfering RNAs followed by transcriptome profiling using microarrays. The 59 BACH1 target genes identified by chromatin immunoprecipitation sequencing were found highly enriched in genes showing expression changes after BACH1 knockdown, demonstrating the impact of BACH1 repression on transcription. In addition to known and new BACH1 targets involved in heme degradation (HMOX1, FTL, FTH1, ME1, and SLC48A1) and redox regulation (GCLC, GCLM, and SLC7A11), we also discovered BACH1 target genes affecting cell cycle and apoptosis pathways (ITPR2, CALM1, SQSTM1, TFE3, EWSR1, CDK6, BCL2L11, and MAFG) as well as subcellular transport processes (CLSTN1, PSAP, MAPT, and vault RNA). The newly identified impact of BACH1 on genes involved in neurodegenerative processes and proliferation provides an interesting basis for future dissection of BACH1-mediated gene repression in neurodegeneration and virus-induced cancerogenesis.

    Autoimmune disease is one of the leading causes of morbidity and mortality worldwide. In Addison's disease, the adrenal glands are targeted by destructive autoimmunity. Despite being the most common cause of primary adrenal failure, little is known about its aetiology. To understand the genetic background of Addison's disease, we utilized the extensively characterized patients of the Swedish Addison Registry. We developed an extended exome capture array comprising a selected set of 1853 genes and their potential regulatory elements, for the purpose of sequencing 479 patients with Addison's disease and 1394 controls. We identified BACH2 (rs62408233-A, OR = 2.01 (1.71-2.37), P = 1.66 × 10 -15 , MAF 0.46/0.29 in cases/controls) as a novel gene associated with Addison's disease development. We also confirmed the previously known associations with the HLA complex. Whilst BACH2 has been previously reported to associate with organ-specific autoimmune diseases co-inherited with Addison's disease, we have identified BACH2 as a major risk locus in Addison's disease, independent of concomitant autoimmune diseases. Our results may enable future research towards preventive disease treatment. © 2016 The Authors.

    Saban, Mark

    2015-11-01

    This paper responds to a recent paper by Wolfgang Giegerich entitled 'Two Jungs: apropos a paper by Mark Saban'. Giegerich disputes my assertion that the 'rigorous notion' at the heart of his psychology 'finds no source in Jung's psychology, implicit or explicit'. In order to do this he posits the existence of two Jungs, an exoteric Jung and an esoteric Jung. The implications of Giegerich's binary scission of Jung are explored in this paper, and show that the tendency to exalt one Jung while disparaging the other betrays a comprehensive blindness toward the contradictory complexity of Jung's psychology as a whole. It is suggested that this blindness is the consequence of Giegerich's systematic prioritization of a neo-Hegelian agenda that is in profound conflict with the telos of Jung's psychology. © 2015, The Society of Analytical Psychology.

    "The Innermost Kernel" recounts the physicist and Nobel Laureate Wolfgang Pauli and his interest in Jungian psychology, philosophy and western world-view. It is also an exploration of the intellectual setting and context of Pauli's thinking, which has its starting point in the cultural and intellectual climate of fin-de-siècle Europe. As a contribution to the general history of quantum physics this study has a special focus on the psychological and philosophical issues discussed by physicists belonging to the Copenhagen school. The work is mainly based on the correspondence of the principle characters and explores some of the central issues discussed there, as for instance the subject-object relation, complementarity, the relation of conscious and unconscious, the process underlying concept-formation, the psychology of scientific discovery, the symbolic world of alchemy, the theories of archetypes and of synchronicity. Ultimately this book is about a remarkable scientist searching for a new understanding of ...

    2012-01-01

    Inequalities arise as an essential component in various mathematical areas. Besides forming a highly important collection of tools, e.g. for proving analytic or stochastic theorems or for deriving error estimates in numerical mathematics, they constitute a challenging research field of their own. Inequalities also appear directly in mathematical models for applications in science, engineering, and economics. This edited volume covers divers aspects of this fascinating field. It addresses classical inequalities related to means or to convexity as well as inequalities arising in the field of ordinary and partial differential equations, like Sobolev or Hardy-type inequalities, and inequalities occurring in geometrical contexts. Within the last five decades, the late Wolfgang Walter has made great contributions to the field of inequalities. His book on differential and integral inequalities was a real breakthrough in the 1970’s and has generated a vast variety of further research in this field. He also organize...

    The upgrade of the TEXTOR tokamak at KFA Juelich was recently completed. This upgrade extended the TEXTOR pulse length from 5 seconds to 10 seconds. The auxiliary heating was increased to a total of 8.0 MW through a combination of neutral beam injection and radio frequency heating. Originally, the inertially cooled armor tiles of the full toroidal belt Advanced Limiter Test -- II (ALT-II) were designed for a 5-second operation with total heating of 6.0 MW. The upgrade of TEXTOR will increase the energy deposited per pulse onto the ALT-II by about 300%. Consequently, the graphite armor tiles for the ALT-II had to be redesigned to avoid excessively high graphite armor surface temperatures that would lead to unacceptable contamination of the plasma. This redesign took the form of two major changes in the ALT-II armor tile geometry. The first design change was an increase of the armor tile thermal mass, primarily by increasing the radial thickness of each tile from 17 mm to 20 mm. This increase in the radial tile dimension reduces the overall pumping efficiency of the ALT-II pump limiter by about 30%. The reduction in exhaust efficiency is unfortunate, but could be avoided only by active cooling of the ALT-II armor tiles. The active cooling option was too complicated and expensive to be considered at this time. The second design change involved redefining the plasma facing surface of each armor tile in order to fully utilize the entire surface area. The incident charged particle heat flux was distributed uniformly over the armor tile surfaces by carefully matching the radial, poloidal and toroidal curvature of each tile to the plasma flow in the TEXTOR boundary layer. This geometry redefinition complicates the manufacturing of the armor tiles, but results in significant thermal performance gains. In addition to these geometry upgrades, several material options were analyzed and evaluated

    The upgrade of the TEXTOR tokamak at KFA Julich will be completed in the spring of 1994. The upgrade will extend the TEXTOR pulse length from 5 seconds to 10 seconds. The auxiliary heating systems are also scheduled to be upgraded so that eventually a total of 8.0 MW auxiliary heating will be available through a combination of neutral beam injection and radio frequency heating. Originally, the inertially cooled armor tiles on the full toroidal belt Advanced Limiter Test - II (ALT-II) were designed for 5-second operation with a total heating power of 6.0 MW. The upgrade of TEXTOR will increase the energy deposited per pulse onto ALT-II by more than 300%. Consequently, the graphite armor tiles for ALT-II had to be redesigned in order to increase their thermal inertia and, thereby, avoid excessively high graphite armor surface temperatures that would lead to unacceptable contamination of the plasma. The armor tile thermal inertia had been increase primarily by expanding the radial thickness of the tiles from 17 mm to 20 mm. This increase in radial tile dimension will reduce the overall pumping efficiency of the ALT-II pump limiter by about 30%. The final armor tile design was a compromise between increasing the power handling capability and reducing the particle exhaust efficiency of ALT-II. The reduction in exhaust efficiency is unfortunate, but could only be avoided by active cooling of the ALT-II armor tiles. The active cooling option was too complicated and expensive to be considered at this time

    Edge electric fields have been related to H-mode-like behaviour. The experiments reported here are an attempt to control the SOL profiles by electrostatic biasing of the full toroidal-belt limiter ALT-II. The specific goals are: influencing the edge particle flows, particle removal, power deposition and the global confinement. The ALT-II pump limiter is a full toroidal belt located at 45 o below the outer midplane and consisting of eight graphite covered blades which can be independently biased. Particle scoops located behind the limiter neutralize and direct the incoming plasma into the pumping ducts. (author) 5 refs., 3 figs

  2. Surface and Subsurface Meltwater Ponding and Refreezing on the Bach Ice Shelf, Antarctic Peninsula

    There is growing concern about the stability and fate of Antarctic ice shelves, as four major ice shelves on the Antarctic Peninsula have completely disintegrated since the 1950s. Their collapse has been linked to the southward movement of the -9 oC mean annual temperature isotherm. The proximal causes of ice shelf instability are not fully known, but an increase in surface melting leading to water ponding and ice flexure, fracture and calving has been implicated. Close to the recently collapsed Wilkins Ice Shelf, the Bach Ice Shelf (72°S 72°W) may be at risk from break up in the near future. Here, we document the changing surface hydrology of the Bach Ice Shelf between 2001 and 2017 using Landsat 7 & 8 imagery. Extensive surface water is identified across the Bach Ice Shelf and its tributary glaciers. Two types of drainage system are observed, drainage into firn via simple stream networks and drainage into the ocean via more complex networks. There are differences between the surface hydrology on the ice shelf and the tributary glaciers, as well as variations within and between summer seasons linked to surface air temperature fluctuations. We also document the changing subsurface hydrology of the ice shelf between 2014 and 2017 using Sentinel 1 A/B SAR imagery. Forty-five subsurface features are identified and analysed for their patterns and temporal evolution. Fourteen of the features show similar characteristics to previously-identified buried lakes and some occur in areas associated with surface lakes in previous years. The buried lakes show seasonal variability in area and surface backscatter, which varies with surface air temperature, and are consistent with the presence, enlargement and contraction of liquid water bodies. Buried lakes are an overlooked source of water loading on ice shelves, which may contribute to ice shelf flexure and potential fracture.

    Tourette's syndrome is a clinical condition characterized by multiple motor tics and vocal tics which occurs in the age range 5-25 years and the intensity of the symptoms changes with time. It is felt that at least two remarkable personalities namely, Dr. Samuel Johnson from England, a man of letters and the compiler of the first ever English dictionary, and Wolfgang Amadeus Mozart from Austria, one of the greatest musical genius of all time, possibly suffered from this condition. Tourette's syndrome is often described as the classical borderzone between neurology and psychiatry and every neurologist wonders at the curious and fascinating clinical features of this condition. It seems that at least two remarkable personalities, Dr. Samuel Johnson, a man of letters and the first person to compile an English dictionary, and Wolfgang Amadeus Mozart, arguably the most creative musical composer of all time, were possibly afflicted with this condition.

    El padre de la música moderna, Juan Sebastián Bach, inauguró el milenio con explosiones armoniosas en todo el planeta, al conmemorarse 250 años de la finalización de su ciclo vital.

    Como ya lo hemos indicado, la presidencia de la Academia ha querido intercalar las sesiones ordinarias con otras de tipo cultural y aprovechó este importante aniversario para hacer su contribución, al igual que lo hicieron otras importantes instituciones del país.

    Por esta razón, el académico Roso Alfredo Cala Hederich nos obsequió con una agradable velada de antología, en la cual combinó la audición de trozos musicales que en su sentir representan lo mejor de la música del genio alemán (en ocasiones sirviendo de “melopea” o música de fondo para su presentación oral, con extraordinarios videos de paisajes y edificios por donde transcurrió la vida de uno de los tres más grandes compositores mundiales, junto con Beethoven y Mozart posteriormente.

    Bach fue la máxima expresión musical de una familia de muchos miembros cuyo oficio artesanal fue tocar, enseñar, crear y perfeccionar la música, que fue exitosa “in crescendo” a partir del primer Bach, llegó a su clímax con J.Sebastián y fue paulatinamente decayendo hasta llegar a la buena calidad, mas no extraordinaria.

    Full Text Available During the XVII to XVIII centuries, musical theorists, especially in Protestant circles compiled, classified and published diverse constructive procedures (figures used by renaissance composers and their immediate precursors in order to express sub specie musicae the meaning of texts. In this way, composition techniques became "idiomatical". J. S. Bach's contribution in this field has been investigated and acknowledged by musicologists throughout history. For some time now, evangelical theology has been taking an interest in that particular aspect of Bach's music, as it is obvious that in order to find an explanation for texts both devout and biblical it is often useful to analyse artistic expressions of the said texts, given that, going down that path theology will learn to understand and listen to them in a new light. That is where music, more so than other art forms, acquires special importance.Durante los siglos XVII-XVIII, los teóricos de música, especialmente en ambientes protestantes, recogen, sistematizan y dan a conocer diversos procedimientos constructivos (figuras usados por los compositores renacentistas e inmediatamente posteriores para expresar sub specie musicae el contenido del texto. De este modo, la técnica de composición musical se va "idiomatizando". La aportación de J. S. Bach, en este sentido, ha sido estudiada y reconocida por la musicología histórica. Hace un tiempo, también la teología evangélica ha comenzado a interesarse en este aspecto de la música de Bach, pues parece claro, que la explicación de los textos bíblicos o devocionales puede tener éxito por medio del trabajo artístico sobre dichos textos, ya que, por este camino, la teología aprende a oírlos y entenderlos de un modo nuevo. Es aquí donde la música, mucho más que el resto de las artes, adquiere una especial importancia.

    BTB and CNC homolog 1 (Bach1) is a transcriptional repressor of heme oxygenase-1 (HO-1), which plays an important role in the protection of cells and tissues against acute and chronic inflammation. However, the role of Bach1 in the gastrointestinal mucosal defense system remains little understood. HO-1 supports the suppression of experimental colitis and localizes mainly in macrophages in colonic mucosa. This study was undertaken to elucidate the Bach1/HO-1 system's effects on the pathogenesis of experimental colitis. This study used C57BL/6 (wild-type) and homozygous Bach1-deficient C57BL/6 mice in which colonic damage was induced by the administration of an enema of 2,4,6-trinitrobenzene sulfonic acid (TNBS). Subsequently, they were evaluated macroscopically, histologically, and biochemically. Peritoneal macrophages from the respective mice were isolated and analyzed. Then, wild-type mice were injected with peritoneal macrophages from the respective mice. Acute colitis was induced similarly. TNBS-induced colitis was inhibited in Bach1-deficient mice. TNBS administration increased the expression of HO-1 messenger RNA and protein in colonic mucosa in Bach1-deficient mice. The expression of HO-1 mainly localized in F4/80-immunopositive and CD11b-immunopositive macrophages. Isolated peritoneal macrophages from Bach1-deficient mice highly expressed HO-1 and also manifested M2 macrophage markers, such as Arginase-1, Fizz-1, Ym1, and MRC1. Furthermore, TNBS-induced colitis was inhibited by the transfer of Bach1-deficient macrophages into wild-type mice. Deficiency of Bach1 ameliorated TNBS-induced colitis. Bach1-deficient macrophages played a key role in protection against colitis. Targeting of this mechanism is applicable to cell therapy for human inflammatory bowel disease.

    The transcriptional factor Bach1 forms a heterodimer with small Maf family, and functions as a repressor of the Maf recognition element (MARE) in vivo. To investigate the involvement of Bach1 in the heme-dependent regulation of the expression of the α-globin gene, human erythroleukemia K562 cells were cultured with succinylacetone (SA), a heme biosynthetic inhibitor, and the level of α-globin mRNA was examined. A decrease of α-globin mRNA was observed in SA-treated cells, which was restored by the addition of hemin. The heme-dependent expression of α-globin occurred at the transcriptional level since the expression of human α-globin gene promoter-reporter gene containing hypersensitive site-40 (HS-40) was decreased when K562 cells were cultured with SA. Hemin treatment restored the decrease of the promoter activity by SA. The regulation of the HS-40 activity by heme was dependent on the NF-E2/AP-1 (NA) site, which is similar to MARE. The NA site-binding activity of Bach1 in K562 increased upon SA-treatment, and the increase was diminished by the addition of hemin. The transient expression of Bach1 and mutated Bach1 lacking CP motifs suppressed the HS-40 activity, and cancellation of the repressor activity by hemin was observed when wild-type Bach1 was expressed. The expression of NF-E2 strengthened the restoration of the Bach1-effect by hemin. Interestingly, nuclear localization of Bach1 increased when cells were treated with SA, while hemin induced the nuclear export of Bach1. These results indicated that heme plays an important role in the induction of α-globin gene expression through disrupting the interaction of Bach1 and the NA site in HS-40 enhancer in erythroid cells

Diversification analysis of ScAlt1/ScAlt2 indicated that while ScAlt1 is an alanine transaminase, ScAlt2 lost this activity, constituting an example in which one of the members of the gene pair lacks the apparent ancestral physiological role. This paper analyzes structural organization and pyridoxal phosphate (PLP binding properties of ScAlt1 and ScAlt2 indicating functional diversification could have determined loss of ScAlt2 alanine transaminase activity and thus its role in alanine metabolism. It was found that ScAlt1 and ScAlt2 are dimeric enzymes harboring 67% identity and intact conservation of the catalytic residues, with very similar structures. However, tertiary structure analysis indicated that ScAlt2 has a more open conformation than that of ScAlt1 so that under physiological conditions, while PLP interaction with ScAlt1 allows the formation of two tautomeric PLP isomers (enolimine and ketoenamine ScAlt2 preferentially forms the ketoenamine PLP tautomer, indicating a modified polarity of the active sites which affect the interaction of PLP with these proteins, that could result in lack of alanine transaminase activity in ScAlt2. The fact that ScAlt2 forms a catalytically active Schiff base with PLP and its position in an independent clade in “sensu strictu” yeasts suggests this protein has a yet undiscovered physiological function.

    The ALT-I pump limiter is used to control hydrogen fluxes from the TEXTOR tokamak. The performance of two different modules, the open fixed geometry (FG) and the closed variable geometry (VG) is discussed. In unpumped scoop limiter operation, the pressure in the ALT-I chamber increases to 3x10 -4 torr(FG) and 2x10 -3 torr(VG). With pumping, the fraction of particles incident on the neutralizer plate that is removed is 25-50%(FG) and 50-80%(VG). These removed particles are estimated to be 2-4(8)%(FG) and 6-13%(VG) of the total plasma outflux (Nsub(e)/tausub(p)). The collection of helium from the plasma using the FG module is approximately half as effective as hydrogen collection. The higher particle removal efficiency for the VG module is attributed to lower neutral backstreaming. (author)

    Full Text Available It becomes clear that new media begin to function as multiplicators of new worlds, creating numerous virtual environments. This diversified, compound reality in many ways takes a shape of a network. New media art in this field of events has various functions. From one hand, it is one of the most refined instruments in the process of networkisation. From the other hand, it is also the tool of verification for these processes, critically but without prejudice evaluating its development, attentively observing what shapes do they took, as well as their real or possible results. In each case, new media art is an active participant of these processes, making full use of possibilities provided by the network system. Frequently while performing its activities it is intersected or linked with the processes which are a part of the world of science, creating together with them new cultural paradigm. Monika Fleischmann and Wolfgang Strauss undertook their joint, creative actions in combined fields of art and science in late 1980s. It was a special moment of a breakthrough for the formation of the character of modern civilization. Events taking place back then, as being a part of a sphere of phenomena generated by communication and information sciences, had enormous influence on the process of shaping a new cultural formation – cyber culture, and because of this, at the same time, had enormous influence on our ways of reality perception. From the beginning of their cooperation, Fleischmann and Strauss have found the tools appropriate for the realization of their works in the environemt of the internet. Their’s art has developed in parallel to the development of computer and internet environment, depicting dynamics of this network and inscribing, with the undertaken issues, in the circle of problems generated through out a development and transformations of accompanied cyber-cultural concepts.

    To evaluate the effect of Bach flower Rescue Remedy on the control of risk factors for cardiovascular disease in rats. A randomized longitudinal experimental study. Eighteen Wistar rats were randomly divided into three groups of six animals each and orogastrically dosed with either 200 μl of water (group A, control), or 100 μl of water and 100 μl of Bach flower remedy (group B), or 200 μl of Bach flower remedy (group C) every 2 days, for 20 days. All animals were fed standard rat chow and water ad libitum. Urine volume, body weight, feces weight, and food intake were measured every 2 days. On day 20, tests of glycemia, hyperuricemia, triglycerides, high-density lipoprotein (HDL) cholesterol, and total cholesterol were performed, and the anatomy and histopathology of the heart, liver and kidneys were evaluated. Data were analyzed using Tukey's test at a significance level of 5%. No significant differences were found in food intake, feces weight, urine volume and uric acid levels between groups. Group C had a significantly lower body weight gain than group A and lower glycemia compared with groups A and B. Groups B and C had significantly higher HDL-cholesterol and lower triglycerides than controls. Animals had mild hepatic steatosis, but no cardiac or renal damage was observed in the three groups. Bach flower Rescue Remedy was effective in controlling glycemia, triglycerides, and HDL-cholesterol and may serve as a strategy for reducing risk factors for cardiovascular disease in rats. This study provides some preliminary "proof of concept" data that Bach Rescue Remedy may exert some biological effects. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The Alternative Liquid Fuels Simulation Model (AltSim) is a high-level dynamic simulation model which calculates and compares the production and end use costs, greenhouse gas emissions, and energy balances of several alternative liquid transportation fuels. These fuels include: corn ethanol, cellulosic ethanol from various feedstocks (switchgrass, corn stover, forest residue, and farmed trees), biodiesel, and diesels derived from natural gas (gas to liquid, or GTL), coal (coal to liquid, or CTL), and coal with biomass (CBTL). AltSim allows for comprehensive sensitivity analyses on capital costs, operation and maintenance costs, renewable and fossil fuel feedstock costs, feedstock conversion ratio, financial assumptions, tax credits, CO{sub 2} taxes, and plant capacity factor. This paper summarizes the structure and methodology of AltSim, presents results, and provides a detailed sensitivity analysis. The Energy Independence and Security Act (EISA) of 2007 sets a goal for the increased use of biofuels in the U.S., ultimately reaching 36 billion gallons by 2022. AltSim's base case assumes EPA projected feedstock costs in 2022 (EPA, 2009). For the base case assumptions, AltSim estimates per gallon production costs for the five ethanol feedstocks (corn, switchgrass, corn stover, forest residue, and farmed trees) of $1.86, $2.32, $2.45, $1.52, and $1.91, respectively. The projected production cost of biodiesel is $1.81/gallon. The estimates for CTL without biomass range from $1.36 to $2.22. With biomass, the estimated costs increase, ranging from $2.19 per gallon for the CTL option with 8% biomass to $2.79 per gallon for the CTL option with 30% biomass and carbon capture and sequestration. AltSim compares the greenhouse gas emissions (GHG) associated with both the production and consumption of the various fuels. EISA allows fuels emitting 20% less greenhouse gases (GHG) than conventional gasoline and diesels to qualify as renewable fuels. This allows several of the

  5. Solutions of the linearized Bach-Einstein equation in the static spherically symmetric case

    The Bach-Einstein equation linearized around Minkowski space-time is completely solved. The set of solutions depends on three parameters; a two-parameter subset of it becomes asymptotically flat. In that region the gravitational potential is of the type phi = -m/r + epsilon exp (-r/l). Because of the different asymptotic behaviour of both terms, it became necessary to linearize also around the Schwarzschild solution phi = -m/r. The linearized equation resulting in this case is discussed using qualitative methods. The result is that for m = 2l phi = -m/r + epsilon r -2 exp (-r/l) u, where u is some bounded function; m is arbitrary and epsilon again small. Further, the relation between the solution of the linearized and the full equation is discussed. (author)

    The performance of the Bach-type Savonius wind turbine with a constant cross-section is examined by means of quasi 2D and 3D flow predictions obtained from ANSYS CFX. Simulations were performed in a way allowing for a comparison with the wind tunnel data presented by Kamoji et al. The comparison with the experiment has revealed that 2D solutions give much higher deviation from the reference data than the 3D ones, which guarantees a good solution quality. It can be stated that even simplified (lack of laminar-turbulence transition modelling and a coarser mesh) 3D simulations can yield more accurate results than complex 2D solutions for turbines with a low aspect ratio. The paper also presents a systematic analysis of the most characteristic flow structures which are identified in the rotor.

    This article discusses the eyes of Wolfgang Amadeus Mozart (1756-1791) which, based on portraits, can be said to have a certain noticeable feature--some degree of exophthalmos. In fact, even contemporary observers made particular mention of Mozart's eyes being large. Although cicatricial ectropion, caused by infectious disease, cannot be excluded, mild myopia, in combination with shallow orbits or combined with a genetic predilection, would be one possible explanation for Mozart's large eyes. Graves' orbitopathy, the ophthalmic manifestation of hyperthyroidism, or hypothyroidism have both been suggested to be the cause of Mozart's large eyes. However, these diseases are unlikely causes given their topical and systemic features.

    Full Text Available Abstract Background Bach Flower Remedies are thought to help balance emotional state and are commonly recommended by practitioners for psychological problems and pain. We assessed whether Bach Flower Remedies (BFRs are safe and efficacious for these indications by performing a systematic review of the literature. Methods We searched MEDLINE®, Embase, AMED, and the Cochrane Library from inception until June 2008 and performed a hand-search of references from relevant key articles. For efficacy, we included all prospective studies with a control group. For safety, we also included retrospective, observational studies with more than 30 subjects. Two authors abstracted data and determined risk of bias using a recognised rating system of trial quality. Results Four randomised controlled trials (RCTs and two additional retrospective, observational studies were identified and included in the review. Three RCTs of BFRs for students with examination anxiety, and one RCT of BFRs for children with attention-deficit hyperactivity disorder (ADHD showed no overall benefit in comparison to placebo. Due to the number and quality of the studies the strength of the evidence is low or very low. We did not find any controlled prospective studies regarding the efficacy of BFRs for pain. Only four of the six studies included for safety explicitly reported adverse events. Conclusion Most of the available evidence regarding the efficacy and safety of BFRs has a high risk of bias. We conclude that, based on the reported adverse events in these six trials, BFRs are probably safe. Few controlled prospective trials of BFRs for psychological problems and pain exist. Our analysis of the four controlled trials of BFRs for examination anxiety and ADHD indicates that there is no evidence of benefit compared with a placebo intervention.

  10. Preparatory investigations for a public dialogue on flash flood risk in the Mehlemer Bach catchment, Germany

    On July 3rd, 2010, an extreme precipitation event occurred in the municipality of Wachtberg at the southern urban fringe of the Federal City of Bonn. The 30-min intensity of the torrential rain was estimated to represent a 1000 year event according to the KOSTRA dataset (German Meteorological Service, DWD). Rapid overland flow and the exceedance of the design values of the sewerage system caused a flash flood in the Mehlemer Bach catchment. Roughly 400 buildings were affected in its lower, urbanized part, and it took over two weeks to clear the damage. Similar flash flood events have been recorded in the same catchment regularly since the year 1693, three times in the last 80 years alone. The fact that, in case of the 2010 event, the official weather warning was released almost simultaneously to the beginning of the downpour highlights the urgent need for preparative action in the longer term. Flash flood risk mitigation relies, among others, on risk awareness and preparedness of residents. One aim of this study is to analyse the current risk communication in the drainage area of Mehlemer Bach through questionnaires and expert interviews, which will provide a good basis for an open dialogue between residents and the authorities. There is an urgent need for practical and accessible advice, and it must be ensured that the resources and capabilities of the individuals involved are taken into consideration. In addition, we compare a hazard map of the area to mental maps drawn by the local population in order to assess their risk perception.

    The goal of this project was to determine if the double star's angular separation and position angle measurements could be successfully measured with a motor driven, alt-azimuth Dobsonian-mounted Newtonian telescope (without a field rotator), and a digital single-lens reflex (DSLR) camera. Additionally, the project was constrained by using as much existing equipment as much as possible, including an Apple MacBook Pro laptop and a Canon T2i camera. This project was additionally challenging because the first author had no experience with astrophotography.

    High-alpine environments are strongly affected by glacier retreat since the Little Ice Age (LIA). Due to ongoing climate change the hydrology of proglacial rivers is also influenced. It is expected that the growing proportions of snow melt and rainfall events will change runoff characteristics of proglacial rivers. Additionally, the importance of paraglacial sediment sources in recently deglaciating glacier forefields is increasing, while the role of glacial erosion is declining. Thus complex environmental conditions leading to a complex pattern of fluvial sediment transport in partly glaciated catchments of the European Alps. Under the umbrella of the joint PROSA-project the fluvial sediment transport of the river Riffler Bach (Kaunertal, Tyrol, Austria) was studied in 3 consecutive ablation seasons in order to quantify sediment yields. In June 2012 a probe for water level and an automatic water sampler (AWS) were installed at the outlet of the catchment (20km2). In order to calculate annual stage-discharge-relations by the rating-curve approach, discharge (Q) was repeatedly measured with current meters and by salt dilution. Concurrent to the discharge measurements bed load was collected using a portable Helley-Smith sampler. Bed load samples were weighted and sieved in the laboratory to gain annual bed load rating curves and grain size distributions. In total 564 (2012: 154, 2013: 209, 2014: 201) water samples were collected and subsequently filtered to quantify suspended sediment concentrations (SSC). Q-SSC-relations were calculated for single flood events due to the high variability of suspended sediment transport. The results show a high inter- and intra-annual variability of solid fluvial sediment transport, which can be explained by the characteristics of suspended sediment transport. Only 13 of 22 event-based Q-SSC-relations show causal dependency. In 2012, during a period with multiple pluvial-induced peak discharges most sediment was transported. On the

    Maintaining functional telomeres is important for long-term proliferation of cells. About 15% of cancer cells are telomerase-negative and activate the alternative-lengthening of telomeres (ALT) pathway to maintain their telomeres. Recent studies have shown that the human CTC1/STN1/TEN1 complex (CST) plays a multi-faceted role in telomere maintenance in telomerase-expressing cancer cells. However, the role of CST in telomere maintenance in ALT cells is unclear. Here, we report that human CST forms a functional complex localizing in the ALT-associated PML bodies (APBs) in ALT cells throughout the cell cycle. Suppression of CST induces telomere instabilities including telomere fragility and elevates telomeric DNA recombination, leading to telomere dysfunction. In addition, CST deficiency significantly diminishes the abundance of extrachromosomal circular telomere DNA known as C-circles and t-circles. Suppression of CST also results in multinucleation in ALT cells and impairs cell proliferation. Our findings imply that the CST complex plays an important role in regulating telomere maintenance in ALT cells. - Highlights: • CST localizes at telomeres and ALT-associated PML bodies in ALT cells throughout the cell cycle. • CST is important for promoting telomeric DNA replication in ALT cells. • CST deficiency decreases ECTR formation and increases T-SCE. • CST deficiency impairs ALT cell proliferation and results in multinucleation.

    Immortal human cells maintain telomere length by the expression of telomerase or through the alternative lengthening of telomeres (ALT). The ALT mechanism involves a recombination-like process that allows the rapid elongation of shortened telomeres. However, it is not known whether activation of the ALT pathway affects other sequences in the genome. To address this we have investigated, in ALT-expressing cell lines and tumours, the stability of tandem repeat sequences known to mutate via homologous recombination in the human germline. We have shown extraordinary somatic instability in the human minisatellite MS32 (D1S8) in ALT-expressing (ALT+) but not in normal or telomerase-expressing cell lines. The MS32 mutation frequency varied across 15 ALT+ cell lines and was on average 55-fold greater than in ALT- cell lines. The MS32 minisatellite was also highly unstable in three of eight ALT+ soft tissue sarcomas, indicating that somatic destabilization occurs in vivo. The MS32 mutation rates estimated for two ALT+ cell lines were similar to that seen in the germline. However, the internal structures of ALT and germline mutant alleles are very different, indicating differences in the underlying mutation mechanisms. Five other hypervariable minisatellites did not show elevated instability in ALT-expressing cell lines, indicating that minisatellite destabilization is not universal. The elevation of MS32 instability upon activation of the ALT pathway and telomere length maintenance suggests there is overlap between the underlying processes that may be tractable through analysis of the D1S8 locus.

    Erectile dysfunction (ED) is associated with cardiovascular disease (CVD); however, the association between change in ED status over time and future underlying CVD risk is unclear. The aim of this study was to investigate the association between change in ED status and Framingham CVD risk, as well change in Framingham risk. We studied 965 men free of CVD in the Boston Area Community Health (BACH) Survey, a longitudinal cohort study with three assessments. ED was assessed with the five-item International Index of Erectile Function at BACH I (2002-2005) and BACH II (2007-2010) and classified as no ED/transient ED/persistent ED. CVD risk was assessed with 10-year Framingham CVD risk algorithm at BACH I and BACH III (2010-2012). Linear regression models controlled for baseline age, socio-demographic and lifestyle factors, as well as baseline Framingham risk. Models were also stratified by age (≥/< 50 years). Framingham CVD risk and change in Framingham CVD risk were the main outcome measures. Transient and persistent ED was significantly associated with increased Framingham risk and change in risk over time in univariate and age-adjusted models. In younger men, persistent ED was associated with a Framingham risk that was 1.58 percentage points higher (95% confidence interval [CI]: 0.11, 3.06) and in older men, a Framingham risk that was 2.54 percentage points higher (95% CI: -1.5, 6.59), compared with those without ED. Change in Framingham risk over time was also associated with transient and persistent ED in men <50 years, but not in older men. Data suggest that even after taking into account other CVD risk factors, transient and persistent ED is associated with Framingham CVD risk and a greater increase in Framingham risk over time, particularly in younger men. Findings further support clinical assessment of CVD risk in men presenting with ED, especially those under 50 years. © 2014 International Society for Sexual Medicine.

The selected concert is of historical importance for the prominent role assumed by the harpsichord in comparison to the other two soloists (flute and violin. The didactic “bridge” that is useful to deal with this piece and carve out the cognitive contents ad hoc has been identified by Giorgio Pagannone in Walt Disney’s animated cartoon, Three Little Pigs (1933, based on a fairy tale of the same name.First, we present and analyse  the music piece and animated cartoon. Next, we provide a detailed and articulated description of the pedagogic unit, that was adopted by Silvia Cancedda in a primary school in Bologna (Italy and produced very good results such as the intuitive reading of selected score fragments.

    Pb S-doped CdS nano materials were successfully synthesized using chemical bath. Transmittance measurements were used to estimate the optical band gap energy. Tailing in the band gap was observed and found to obey Ur bach rule. The diffraction X-ray show that the size of crystallites is in the ∼33 nm to 12 nm range. The peaks belonging to primary phase are identified at 2θ = 26.5 degrees Celsius and 2θ = 26.00 degrees Celsius corresponding to CdS and Pb S respectively. Thus, a shift in maximum intensity peak from 2θ = 26.4 to 28.2 degrees Celsius is clear indication of possible transformation of cubic to hexagonal phase. Also peaks at 2θ = 13.57, 15.9 degrees Celsius correspond to lead perchlorate thiourea. The effects on films thickness and substrate doping on the band gap energy and the width on tail were investigated. Increasing doping give rise to a shift in optical absorption edge ∼0.4 eV.

    Harmony is a fundamental attribute of music. Close connections exist between music and mathematics since both pursue harmony and unity. In music, the consonance of notes played simultaneously partly determines our perception of harmony; associates with aesthetic responses; and influences the emotion expression. The consonance could be considered as a window to understand and analyze harmony. Here for the first time we used a 1/f fluctuation analysis to investigate whether the consonance fluctuation structure in music with a wide range of composers and genres followed the scale free pattern that has been found for pitch, melody, rhythm, human body movements, brain activity, natural images and geographical features. We then used a network graph approach to investigate which composers were the most influential both within and across genres. Our results showed that patterns of consonance in music did follow scale-free characteristics, suggesting that this feature is a universally evolved one in both music and the living world. Furthermore, our network analysis revealed that Bach's harmony patterns were having the most influence on those used by other composers, followed closely by Mozart.

  20. Geometry of deformed black holes. II. Schwarzschild hole surrounded by a Bach-Weyl ring

    2016-08-01

    We continue to study the response of black-hole space-times on the presence of additional strong sources of gravity. Restricting ourselves to static and axially symmetric (electro)vacuum exact solutions of Einstein's equations, we first considered the Majumdar-Papapetrou solution for a binary of extreme black holes in a previous paper, while here we deal with a Schwarzschild black hole surrounded by a concentric thin ring described by the Bach-Weyl solution. The geometry is again revealed on the simplest invariants determined by the metric (lapse function) and its gradient (gravitational acceleration), and by curvature (Kretschmann scalar). Extending the metric inside the black hole along null geodesics tangent to the horizon, we mainly focus on the black-hole interior (specifically, on its sections at constant Killing time) where the quantities behave in a way indicating a surprisingly strong influence of the external source. Being already distinct on the level of potential and acceleration, this is still more pronounced on the level of curvature: for a sufficiently massive and/or nearby (small) ring, the Kretschmann scalar even becomes negative in certain toroidal regions mostly touching the horizon from inside. Such regions have been interpreted as those where magnetic-type curvature dominates, but here we deal with space-times which do not involve rotation and the negative value is achieved due to the electric-type components of the Riemann/Weyl tensor. The Kretschmann scalar also shapes rather nontrivial landscapes outside the horizon.

Over the past two years as an editorial team we have undertaken a review of the position of ALT-J in relation to other journals in the area and considered the nature and scope of the papers we publish. We continue to expand our list of referees and have provided them with more detailed review forms to help guide them when considering recommendations on submissions and to encourage detailed, critical (and hopefully! helpful feedback to authors. We would like to take this opportunity to thank all the referees for their involvement and commitment to the journal and for their continued work on refereeing papers. As part of the review process we will be moving to a new publisher, Taylor and Francis, commencing with Volume 12; this is, in part, driven by a desire to increase our international profile and readership, as well as seeking to have a better online presence including electronic access to all papers. We are, after all, a research journal on learning technologies! We are looking forward to taking the journal forward with Taylor and Francis but would also like to take this opportunity to thank our current publisher, University of Wales Press, for all their support and professional work over the years; it has been very good working with them.

    In the Bach Dang-Cam Estuary, northern Vietnam, mechanisms governing cohesive sediment aggregation were investigated in situ in 2008-2009. As part of the Red River delta, this estuary exhibits a marked contrast in hydrological conditions between the monsoon and dry seasons. The impact on flocculation processes was assessed by means of surveys of water discharge, suspended particulate matter concentration and floc size distributions (FSDs) conducted during a tidal cycle at three selected sites along the estuary. A method was developed for calculating the relative volume concentration for the modes of various size classes from FSDs provided by the LISST 100X (Sequoia Scientific Inc.). It was found that all FSDs comprised four modes identified as particles/flocculi, fine and coarse microflocs, and macroflocs. Under the influence of the instantaneous turbulent kinetic energy, their proportions varied but without significant modification of their median diameters. In particular, when the turbulence level corresponded to a Kolmogorov microscale of less than ˜235 μm, a major breakup of flocs resulted in the formation of particles/flocculi and fine microflocs. Fluctuations in turbulence level were governed by seasonal variations in freshwater discharge and by the tidal cycle. During the wet season, strong freshwater input induced a high turbulent energy level that tended to generate sediment transfer from the coarser size classes (macroflocs, coarse microflocs) to finer ones (particles/flocculi and fine microflocs), and to promote a transport of sediment seawards. During the dry season, the influence of tides predominated. The turbulent energy level was then only episodically sufficiently high to generate transfer of sediment between floc size classes. At low turbulent energy, modifications in the proportions of floc size classes were due to differential settling. Tidal pumping produced a net upstream transport of sediment.

    BACH, the new soft x-ray beamline for polarization dependent experiments at the Italian synchrotron radiation facility ELETTRA, has been commissioned, characterized and opened to external users. Based on two APPLE II undulators, it covers an energy range between 35 eV and 1600 eV with the control of the light polarization. The monochromator works either in high resolution or high flux mode. Resolving powers of 16000 at 50 eV, 12000 at 90 eV, more than 12000 at 400 eV, 15000 at 534 eV and 6600 at 867 eV have been achieved with the three high resolution gratings. The resolving powers of the high flux grating, which covers the 290 - 1600 eV range, have been measured reaching 7000 at 400 eV and 2200 at 867 eV. The fluxes, in the high resolution mode, range between 4·1011 photons/s at 125 eV and 2·1010 photons/s at about 1100 eV. Using the high flux grating with the best resolution achievable 1.7·1011 photons/s impinge on the sample at 900 eV. Two branches are installed after the monochromator allowing the set-up of two different experimental stations. One of them, besides several facilities for surface preparation and analysis, hosts a compact inelastic soft x-ray spectrometer (ComIXS) dedicated to x-ray emission experiments exploiting the small spot (10 μm in the vertical direction) on the sample. The other branch hosts a liquid helium cryostat equipped with a superconducting coil to perform absorption and transmission experiments with temperatures down to 2 K and magnetic field up to ±7 T

    Full Text Available The aim of the study was to evaluate the ability of Alternaria isolates from workplaces to produce Alt a 1 allergenic protein, and to analyze whether technical materials (cellulose, compost, leather present within the working environment stimulate or inhibit Alt a 1 production (ELISA test. Studies included identification of the isolated molds by nucleotide sequences analyzing of the ITS1/ITS2 regions, actin, calmodulin and Alt a 1 genes. It has been shown that Alternaria molds are significant part of microbiocenosis in the archive, museum, library, composting plant and tannery (14%–16% frequency in the air. The presence of the gene encoding the Alt a 1 protein has been detected for the strains: Alternaria alternata, A. lini, A. limoniasperae A. nobilis and A. tenuissima. Environmental strains produced Alt a 1 at higher concentrations (1.103–6.528 ng/mL than a ATCC strain (0.551–0.975 ng/mL. It has been shown that the homogenization of the mycelium and the use of ultrafiltration allow a considerable increase of Alt a 1 concentration. Variations in the production of Alt a 1 protein, depend on the strain and extraction methods. These studies revealed no impact of the technical material from the workplaces on the production of Alt a 1 protein.

    Autoimmune Addison's disease (AAD) is a rare but highly heritable condition. The BACH2 protein plays a crucial role in T lymphocyte maturation, and allelic variation in its gene has been associated with a number of autoimmune conditions. We aimed to determine whether alleles of the rs3757247 single nucleotide polymorphism (SNP) in the BACH2 gene are associated with AAD. This case-control association study was performed in two phases using Taqman chemistry. In the first phase, the rs3757247 SNP was genotyped in 358 UK AAD subjects and 166 local control subjects. Genotype data were also available from 5154 healthy UK controls from the Wellcome Trust (WTCCC2) for comparison. In the second phase, the SNP was genotyped in a validation cohort comprising 317 Norwegian AAD subjects and 365 controls. The frequency of the minor T allele was significantly higher in subjects with AAD from the United Kingdom compared to both the local and WTCCC2 control cohorts (58% vs 45 and 48%, respectively) (local controls, P = 1.1 × 10 -4 ; odds ratio [OR], 1.68; 95% confidence interval [CI], 1.29-2.18; WTCCC2 controls, P = 1.4 × 10 -6 ; OR, 1.44; 95% CI, 1.23-1.69). This finding was replicated in the Norwegian validation cohort (P = .0015; OR, 1.41; 95% CI, 1.14-1.75). Subgroup analysis showed that this association is present in subjects with both isolated AAD (OR, 1.53; 95% CI, 1.22-1.92) and autoimmune polyglandular syndrome type 2 (OR, 1.37; 95% CI, 1.12-1.69) in the UK cohort, and with autoimmune polyglandular syndrome type 2 in the Norwegian cohort (OR, 1.58; 95% CI, 1.22-2.06). We have demonstrated, for the first time, that allelic variability at the BACH2 locus is associated with susceptibility to AAD. Given its association with multiple autoimmune conditions, BACH2 can be considered a "universal" autoimmune susceptibility locus.

    Full Text Available Tourette′s syndrome is a clinical condition characterized by multiple motor tics and vocal tics which occurs in the age range 5-25 years and the intensity of the symptoms changes with time. It is felt that at least two remarkable personalities namely, Dr. Samuel Johnson from England, a man of letters and the compiler of the first ever English dictionary, and Wolfgang Amadeus Mozart from Austria, one of the greatest musical genius of all time, possibly suffered from this condition. Tourette′s syndrome is often described as the classical borderzone between neurology and psychiatry and every neurologist wonders at the curious and fascinating clinical features of this condition. It seems that at least two remarkable personalities, Dr. Samuel Johnson, a man of letters and the first person to compile an English dictionary, and Wolfgang Amadeus Mozart, arguably the most creative musical composer of all time, were possibly afflicted with this condition.

    Because classical music has greatly affected our life and culture in its long history, it has attracted extensive attention from researchers to understand laws behind it. Based on statistical physics, here we use a different method to investigate classical music, namely, by analyzing cumulative distribution functions (CDFs) and autocorrelation functions of pitch fluctuations in compositions. We analyze 1,876 compositions of five representative classical music composers across 164 years from Bach, to Mozart, to Beethoven, to Mendelsohn, and to Chopin. We report that the biggest pitch fluctuations of a composer gradually increase as time evolves from Bach time to Mendelsohn/Chopin time. In particular, for the compositions of a composer, the positive and negative tails of a CDF of pitch fluctuations are distributed not only in power laws (with the scale-free property), but also in symmetry (namely, the probability of a treble following a bass and that of a bass following a treble are basically the same for each composer). The power-law exponent decreases as time elapses. Further, we also calculate the autocorrelation function of the pitch fluctuation. The autocorrelation function shows a power-law distribution for each composer. Especially, the power-law exponents vary with the composers, indicating their different levels of long-range correlation of notes. This work not only suggests a way to understand and develop music from a viewpoint of statistical physics, but also enriches the realm of traditional statistical physics by analyzing music.

    In this work, we investigated a potential mechanism behind the observation of increased aminotransferase levels in a phase I clinical trial using a lipid-lowering drug, the peroxisome proliferator-activated receptor (PPAR) α agonist, AZD4619. In healthy volunteers treated with AZD4619, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities were elevated without an increase in other markers for liver injury. These increases in serum aminotransferases have previously been reported in some patients receiving another PPARα agonist, fenofibrate. In subsequent in vitro studies, we observed increased expression of ALT1 protein and mRNA in human hepatocytes after treatment with fenofibric acid. The PPAR effect on ALT1 expression was shown to act through a direct transcriptional mechanism involving at least one PPAR response element (PPRE) in the proximal ALT1 promoter, while no effect of fenofibrate and AZD4619 was observed on the ALT2 promoter. Binding of PPARs to the PPRE located at - 574 bp from the transcriptional start site was confirmed on both synthetic oligonucleotides and DNA in hepatocytes. These data show that intracellular ALT expression is regulated by PPAR agonists and that this mechanism might contribute to increased ALT activity in serum

  17. The psychologist who is not a psychologist: a deconstructive reading of Wolfgang Giegerich's idea of psychology proper.

    Science.gov (United States)

    Marlan, Stanton

    2016-04-01

    This paper represents an archetypal and deconstructive reading of the work of Wolfgang Giegerich. In an attempt to extend and philosophically develop Jung's late-life view of the objective psyche, Giegerich, via Hegel, defines psychology proper as fundamentally separate from the everyday person and the 'human, all-too-human' aspects of the soul. It is argued that, in so doing, Giegerich removes the human person from being the primary focus of his psychology and creates instead a hierarchy of ideas and values privileging syntax over semantics, the logical over the empirical, and thinking over imagination. This bypasses the emotionality of the everyday person/patient and also renders psychology proper unable to address the day-to-day practice of the analyst. Giegerich attempts to rectify this problem by re-incorporating what he had previously rejected, making his theory more complex than is apparent in his binary oppositions. In the end, however, it remains a question to what extent Giegerich is successful in avoiding a binary scission (Saban 2015) or a tendency to regularly de-emphasize the human aspect of the soul (Hoedl 2015) in his need to continue to heroically push off from the ego seeking total freedom from neurosis and from our humanity. © 2016, The Society of Analytical Psychology.

  18. Pattern of AST and ALT changes in Relation to Hemolysis in sickle cell Disease

    2011-01-01

    Full Text Available Background Elevated aminotransferase levels are commonly associated with compromised hepatic integrity from various insults. In sickle cell disease, aspartate transaminase (AST is also released via intravascular hemolysis. This study was done to determine the pattern of changes in AST and alanine transaminase (ALT, in particular the AST:ALT ratio, and to relate these to the hemolytic state, which we consider to be more important than hepatic and cardiac dysfunction in some individuals with sickle cell disease. Methods Serum aminotransferase levels were measured in 330 subjects with sickle cell disease, as well as hemoglobin, reticulocytes, and lactate dehydrogenase. The AST:ALT ratio was designated as a hemolytic marker, and simple and multivariate regression analyses were carried out between this ratio and other hemolytic markers. Results Mean AST and ALT levels were 48.24 % 27.78 and 26.48 % 22.73 U/L, respectively. However, for 49 subjects without sickle cell disease, mean AST and ALT levels were the same, ie, 23.0 U/L. In the subjects with sickle cell disease, the increases in AST levels were far higher than for ALT, supporting its release via intravascular hemolysis. In 95.8% of the subjects with sickle cell disease, the AST:ALT ratio was > 1, but our results did not suggest overt malfunctioning of the liver and heart in the majority of subjects. Conclusion Regression analyses support the use of the AST:ALT ratio as a hemolytic marker, because it has an inverse association with the hemoglobin level. Whether in steady state or in crisis, provided hepatic and cardiac integrity has not been compromised, subjects with sickle cell disease would have higher AST levels due to the hemolytic nature of the condition. This is the first report highlighting the AST:ALT ratio in sickle cell disease.

    Intensity modulated radiotherapy (IMRT) is one of the modern techniques in cancer treatment, in which dose is delivered optimally into the shape of the tumor and minimally in surround benign tissues. In developed countries, this technique has been performed routinely by Linacs with MLC for tumors at the critical areas. In Vietnam, because of the wet climate, the use of Linacs with MLC is difficult to operate and maintain. However, IMRT can be implemented by Linacs without MLC via independent jaws, Jaws-only IMRT (JO-IMRT), in which beams are separated into many segments with different weights to optimize highest dose in the tumor and lowest dose in the surrounding health organs. Methods: We describe the new treatment technic application and compare it with normal radiotherapy method (3D-CRT). Results: From 7/2008, the Dep of Nuclear Medicine and Oncology at Bach Mai Hospital has been conducting JO-IMRT to treat cancer patients. Up to now, we have 81 cases treated by IMRT including head and neck cancers (NPC, larynx cancer, maxillary sinus cancer, brain tumor), cancers in the thorax (esophagus cancer, lung cancer, breast cancer), cancers in the pelvis (prostate cancer, cervical cancer, rectal cancer). On the average, beam number is from 5 to 9 and 5-9 segments per beam. Treatment time for a fraction is from 6 to 12 minutes with 2.25 Gy for CTV1 per day. Discrepancies of doses were below 3% (0.15 to 2.84%) between planning and practice. In plan, the preeminences with IMRT are clearly superior to 3D radiation therapy. In clinical, almost patients had good respond, whereas side effects were quite less than conventional radiotherapy. Conclusions: JO-IMRT is a modern technic with more advantage than normal 3D-CRT. It help radiation dose to concentrate maximally in treatment target while influence minimally for sensitive surrounding tissues. Another, it is a high technic to appropriate with the climatic condition in Vietnam. (author)

    Full Text Available Telomeres are responsible for protecting chromosome ends in order to prevent the loss of coding DNA. Their maintenance is required for achieving immortality by neoplastic cells and can occur by upregulation of the telomerase enzyme or through a homologous recombination-associated process, the alternative lengthening of telomeres (ALT. The precise mechanisms that govern the activation of ALT or telomerase in tumor cells are not fully understood, although cellular origin may favor one of the other mechanisms that have been found thus far in mutual exclusivity. Specific mutational events influence ALT activation and maintenance: a unifying frequent feature of tumors that acquire this phenotype are the recurrent mutations of the Alpha Thalassemia/Mental Retardation Syndrome X-Linked (ATRX or Death-Domain Associated Protein (DAXX genes. This review summarizes the established criteria about this phenotype: its prevalence, theoretical molecular mechanisms and relation with ATRX, DAXX and other proteins (directly or indirectly interacting and resulting in the ALT phenotype.

    To analyze the expression of HMOX1 and miR-122 in liver biopsy samples obtained from HCV mono-and HIV/HCV co-infected patients in relation to selected clinical parameters, histological examination and IL-28B polymorphism as well as to determine whether HMOX1 expression is dependent on Bach-1. The study group consisted of 90 patients with CHC: 69 with HCV mono and 21 with HIV/HCV co-infection. RT-PCR was used in the analysis of HMOX1, Bach-1 and miR-122 expression in liver biopsy samples and in the assessment of IL-28B single-nucleotide polymorphism C/T (rs12979860) in the blood. Moreover in liver biopsy samples an analysis of HO-1 and Bach-1 protein level by Western Blot was performed. HCV mono-infected patients, with lower grading score (G600000 IU/mL) demonstrated higher expression of HMOX1. In patients with HIV/HCV co-infection, the expression of HMOX1 was lower in patients with lower lymphocyte CD4 count and higher HIV viral load. IL28B polymorphism did not affect the expression of either HMOX1 or miR-122. Higher HMOX1 expression correlated with higher expression of Bach-1 (Spearman's ρ = 0.586, p = 0.000001) and miR-122 (Spearman's ρ = 0.270, p = 0.014059). HMOX1 and miR-122 play an important role in the pathogenesis of CHC in HCV mono-and HIV/HCV co-infected patients. Reduced expression of HMOX1 in patients with HIV/HCV co-infection may indicate a worse prognosis in this group. Our results do not support the importance of Bach-1 in repression of HMOX1 in patients with chronic hepatitis C.

    The ALT-I variable geometry module has been designed to address many of the issues not previously settled by earlier experiments. The goal is to study the basic processes involved in pump limiter operation as well as demonstrate its utility and effect on the plasma. The flexibility and extensive instrumentation of ALT-I will offer a unique opportunity to parameterize operation and facilitate the engineering design of future pump limiters. (orig.)

    Physicians often experience difficulties in motivating patients with non-alcoholic fatty liver disease (NAFLD) to undergo lifestyle changes. The aim of this study is to examine whether 'Donations for Decreased alanine aminotransferase (ALT)' (D4D) prosocial behavior incentive can serve as an effective intrinsic motivational factor in comparison with conventional dietary and exercise intervention alone for NAFLD patients. Twenty-five NAFLD patients with elevated ALT were randomly assigned to a control group that received conventional dietary and exercise intervention alone, or a donation group whereby, as an incentive, we would make a monetary donation to the United Nations World Food Programme (WFP) based on the decrease in their ALT levels achieved over 12 weeks, in addition to receiving control intervention. In a donation group, we would donate US$1 to the WFP for every 1 IU/l of decrease in their ALT levels. There were no differences of pre-treatment clinical characteristics between the two groups. Significant reductions of ALT levels were achieved only in a donation group, although post-treatment ALT levels were not different between the two groups. These patients raised a total of $316 for the WFP. Promoting patients' intrinsic motivation by incorporating 'D4D' prosocial behavior incentive into conventional dietary and exercise intervention may provide a means to improve NAFLD. © The Author 2013.

  6. Carl Jung's interpretation of Wolfgang Pauli's dreams: The Bailey Island, Maine, and New York City seminars of 1936 and 1937

    Science.gov (United States)

    Brown, Richard Paul

    This dissertation reviewed the development of Jung's dream theory and addresses the question as to whether or not Jung was influenced by the dreams of the Nobel Prize winning physicist, Wolfgang Pauli. Jung provided an extensive analysis of Pauli's dreams, which are contained in the lightly edited, unpublished transcripts of lectures delivered in 1936 and 1937. An archival and hermeneutic analysis of the texts reveals a staged process of individuation that Jung related to in many ways because of the parallels to his own personal journey toward individuation. A chronological history of the development of Jung's dream theory is presented, followed by a picture of the relationship between Jung and Pauli. Thereafter, a detailed summary of the seminar transcripts, one given on Bailey Island, Maine, and the other in New York City the following year, is offered with hermeneutic commentary. An analysis of the seminars found that Pauli's dreams did, in part, support Jung's theory. Specifically, while Jung was unable to meet the scientific demands for clear empirical evidence of his dream theory, he did offer his professional and non-professional audiences with a slightly less rigorous example of his dream theory in action, demonstrating that the process shared similarities across peoples, time, and cultures. Additionally, in Pauli he found a superior mind that had gone through the process of individuation in accordance with his theory and his own experience. During the course of research, reference to a document was found in the correspondence in the Jungian Archives in Zurich. This document entitled, "FAREWELL SPEECH, Given by Dr. C. G. Jung on the Occasion of a Dinner Given in His Honor by the Analytical Psychology Club of New York City October 26, 1937" and other related documents were subsequently uncovered in the sub-basement of the Kristine Mann Library in New York City. A synopsis of the discovery and description of the papers contained in the file are discussed in

  7. Melting experiments and field work on Komorní Hùrka volcano, Bohemia, by Johann Wolfgang von Goethe

    Johann Wolfgang von Goethe (1749-1832), eminent author, was also state minister and scientist as well as experimentalist in geology. Together with Döbereiner, a chemist in Jena during that time, he carried out melting experiments in porcelain and pottery kilns with rocks and minerals from the volcanic and pseudo-volcanic edifices in NW Bohemia. These experiments were to prove Goethe's theory, that remelting of an archetype rock would result in volcanic and pseudo-volcanic rocks. Especially the formation of the Komorní Hùrka (Kammerberg) volcano in NW Bohemia attracted Goethe during all his life. He visited this location 19 times in 1808, 1820 and 1822 and made very exact field observations. But the interpretation of these observations varied between volcanistic and neptunistic. In order to find arguments, he examined the effect of fire on rocks and minerals using porcelain and pottery kilns. The experiments did not provide the expected results and thus failed to explain the formation of Komorní Hùrka. During Goethe's geognostic work, including the "pyro-technical" experiments, the neptunism-volcanism-controversy about the formation of basalt raged in Europe, and, more general, about rock formation: neptunism-plutonism. Especially the effect of heat on rocks and minerals, i.e. the phenomenology of fire, played an important role in that discussion. Goethe swayed during his lifetime between neptunism and volcanism. He did not fully accept plutonism because he believed, that processes of nature are generally non-violent and that volcanic eruptions and other catastrophic phenomena are the exception rather than the rule. Therefore he tended to neptunistic ideas. In Goethe's notes there are many indications of this conflict. In contrast, the melting experiments are mentioned only few times. It was, however, possible to establish a picture of his experimental work and his fundamental concepts and ideas.

  8. Contemporary suspended sediment yield of a partly glaciated catchment, Riffler Bach (Tyrol, Austria)

    Due to glacier retreat since the LIA (Little Ice Age) proglacial areas in high mountain landscapes are growing. These systems are characterized by a high geomorphological activity, especially in the fluvial subsystem. Despite the long tradition of geomorphological research in the European Alps there is a still a lack of understanding in the interactions between hydrology, sediment sources, sediments sinks and suspended sediment transport. As emphasized by ORWIN ET AL. (2010) those problems can be solved by gathering data in a higher frequency and/or in a higher spatial resolution or density - both leading to a big amount of data. In 2012 a gauging station was installed at the outlet of the partly glaciated catchment of the Riffler Bach (Kaunertal valley, Tyrol). During the ablation seasons in 2012 and 2013 water stage was logged automatically every 15 minutes. In both seasons discharge was measured at different water levels to calculate a stage-discharge relation. Additionally, water samples were taken by an automatic water sampler. Within 16 sampling cycles with sampling frequencies ranging from 1 to 24 hours 389 water samples have been collected. The samples were filtered to calculate the suspended sediment concentration (SSC) of each sample. Furthermore, the climate station Weißsee provided meteorological data at a 15 minute interval. Due to the high variability in suspended sediment transport in proglacial rivers it is impossible to compute a robust annual Q-SSC-relation. Hence, two other approaches were used to calculate the suspended sediment load (SSL) and the suspended sediment yield (SSY): A) Q-SSC-relations for every single sampling cycle (e.g. GEILHAUSEN ET AL. 2013) B) Q-SSC-relations based on classification of dominant runoff-generating processes (e.g. ORWIN AND SMART 2004). The first approach uses commonly operated analysis methods that are well understood. While the hydro-climatic approach is more feasible to explain discharge generation and to

    Full Text Available The main message carried by this article is that counterpoint can be taken as a model approach for the introduction of contrasting elements, not only in musical composition but also in the generation of ideas in any domain of knowledge. We start by an interdisciplinary review about the power of opposite concepts as constituting elements in nature. This is followed by the description of the DIMAI model for creative thinking, which is founded upon the dual forces of convergent and divergent thinking modalities. The main body of our work is an extraction of divergent modifiers from the Contrapunctus composed by Bach and collected in the Art of Fugue, with simple examples of application to the diversified fields of education and computer science.

    Mammalian polymerase theta (Polθ) is a multifunctional enzyme that promotes error-prone DNA repair by alternative nonhomologous end joining (alt-NHEJ). Here we present structure-function analyses that reveal that, in addition to the polymerase domain, Polθ-helicase activity plays a central role during double-strand break (DSB) repair. Our results show that the helicase domain promotes chromosomal translocations by alt-NHEJ in mouse embryonic stem cells and also suppresses CRISPR-Cas9- mediated gene targeting by homologous recombination (HR). In vitro assays demonstrate that Polθ-helicase activity facilitates the removal of RPA from resected DSBs to allow their annealing and subsequent joining by alt-NHEJ. Consistent with an antagonistic role for RPA during alt-NHEJ, inhibition of RPA1 enhances end joining and suppresses recombination. Taken together, our results reveal that the balance between HR and alt-NHEJ is controlled by opposing activities of Polθ and RPA, providing further insight into the regulation of repair-pathway choice in mammalian cells.

    Full Text Available In this paper, a general time-division alternate binary offset carrier (GTD-AltBOC modulation method is proposed, which is an extension of TD-AltBOC and time-multiplexed offset-carrier quadrature phase shift keying (TMOC-QPSK with high design flexibility. In this method, binary complex subcarriers and a time-division technique with flexible time slot assignment are used to achieve constant envelope modulation of the signal components with a variable power allocation ratio (PAR. The underlying principle of GTD-AltBOC and the constraints related to the PAR are investigated. For the generation of GTD-AltBOC signals, a lookup table (LUT-based scheme is presented; the minimum required clock rate is half or less of that for existing non-time-division methods. The receiver processing complexities are analyzed for three typical receiving modes, and the power spectral densities (PSDs, cross-correlation functions, multiplexing efficiencies and code-tracking performance are simulated; the results show that GTD-AltBOC enables a significant decrease in receiving complexity compared with existing methods while maintaining high performance in terms of multiplexing efficiency and code tracking.

    Full Text Available ntroduction Bisphosphonate-related osteonecrosis of the jaw (BRONJ is a dangerous complication of bisphosphonates, a class of pharmaceutical agents used in numerous bone disorders. No gold standard therapy exists, but recent literature suggests that, in advanced stages, the best results are achieved with aggressive debridement. In this paper, we report our experience of treatment of stage 3 BRONJ of the maxilla with extensive surgical debridement and reconstruction with a chimeric ALT-Vastus lateralis flap. Methods Five selected patients with stage 3 BRONJ underwent partial maxillectomy with disease-free margins followed by immediate reconstruction with a chimeric ALT-Vastus lateralis free flap. Results Only two patients experienced minor complications. All other patients healed uneventfully within two weeks and donor site morbidity was minimal. Conclusions Our data suggest that aggressive debridement and reconstruction with a chimeric ALT -Vastus lateralis flap is an effective option for the treatment of stage III BRONJ of the maxilla.

    Multiple pathways modulate the dynamic mutability of trinucleotide repeats (TNRs), which are implicated in neurodegenerative disease and evolution. Recently, we reported that environmental stresses induce TNR mutagenesis via stress responses and rereplication, with more than 50% of mutants carrying deletions or insertions-molecular signatures of DNA double-strand break repair. We now show that knockdown of alt-nonhomologous end joining (alt-NHEJ) components-XRCC1, LIG3, and PARP1-suppresses stress-induced TNR mutagenesis, in contrast to the components of homologous recombination and NHEJ, which have no effect. Thus, alt-NHEJ, which contributes to genetic mutability in cancer cells, also plays a novel role in environmental stress-induced TNR mutagenesis. Published by Elsevier Ltd.

  16. Langmuir probe measurements in the TEXTOR tokamak during ALT-I pump limiter experiments

    Langmuir probes have been used to characterize the edge plasma of the TEXTOR tokamak and measure the parameters of the plasma incident on the ALT-I pump limiter during ohmic and ICRH heating. Probes mounted directly on the ALT limiter, and a scanning probe located 90 0 toroidally from the limiter, provide data for the evaluation of pump limiter performance and its effect on the edge plasma. The edge plasma is characterized by density and flux e-folding lengths of about 1.8cm when ALT is the main limiter. These scrape-off lengths do not vary significantly as ALT is moved between the normal 42-46cm minor radii, but increase to over 2.2cm when ALT is inserted to 40cm. The flux to probes at a fixed position in the limiter shadow varies by less than 25% for core density changes of a factor of five. This suggests that the global particle confinement time tau/sub p/, scales as the core density. Estimates from the probes indicate that tau/sub p/ is on the order of the energy confinement time, tau/sub E/. The edge electron temperature, T/sub e/, typically decreases by a factor of two when the core density is raised from 1 to 4 x 10 13 cm -3 . The T/sub e/ profile is essentially flat in the limiter shadow, with values of 10-25 eV depending on the core plasma density and ICRH power. ICRH heating increases the electron temperature and flux in proportion to the coupled power. With ALT as the primary limiter and no direct shadowing, the ion side receives 2 to 3 times the flux of the electron side during both ohmic and ICRH heating. The edge plasma is not directly modified by pump limiter operation, but changes with the core plasma density as particle removal lowers the recycling of neutrals in the boundary

    Geraniin, a hydrolysable tannin, used in traditional medicine in Southeast Asia, is known to exhibit various biological activities. As an antioxidant it is known to up-regulate phase II enzyme Heme oxygenase-1 (HO-1). However its mechanism is not clearly understood. Nuclear factor erythroid-derived 2 related factor 2 (Nrf-2) is transcriptionally up-regulated by Extracellular signal-regulated kinase (ERK) 1/2 and retained in nucleus due to inactivated Glycogen synthase kinase 3 beta (GSK-3β). Geraniin additionally down-regulates expression of microRNA 217 and 377 (miR-217 and miR-377) which target HO-1 mRNA. Expression of BTB and CNC homolog 1 (BACH-1), another regulator of HO-1, is also down-regulated by up-regulating microRNA 98 (miR-98), a negative regulator of BACH-1. Thus, geraniin up-regulates HO-1 expression both through activating its positive regulator Nrf-2 and by down-regulating its negative regulator BACH-1. Up-regulation of HO-1 also confers protection to HepG2 cells from tertiary butyl hydroperoxide (TBH) induced cytotoxicity. [BMB Reports 2017; 50(11): 560-565].

    BACH, a soft x-ray beamline for polarization-dependent experiments at the Italian synchrotron radiation facility ELETTRA, was recently completed and characterized. Its performance, in terms of energy resolution, flux and polarization, is presented. Based on two APPLE II undulators, BACH covers the energy range between 35 and 1600 eV with the control of the light polarization. The monochromator is equipped with four gratings and allows one to work either in a high resolution or in a high flux mode. After the monochromator, the beamline is split into two branches with different refocusing properties. One is optimized to exploit the performance of the soft x-ray spectrometer (ComIXS) available at the beamline. Resolving powers between 12000 at 90 eV photon energy and 6600 near 867 eV were achieved using the high-resolution gratings and the smallest available slit width (10 μm). For the high-brilliance grating, which works between 290 and 1600 eV, resolving powers between 7000 at 400 eV and 2200 at 867 eV were obtained. The flux in the experimental chamber, measured with the high-resolution gratings for linearly polarized light at the best achievable resolution, ranges between 4x10 11 photons/s at 125 eV and 2x10 10 photons/s between 900 and 1250 eV. In circularly polarized mode the flux is two times larger for energies up to 380 eV. A gain of nearly one order of magnitude is obtained for the high-brilliance grating, in accordance with theoretical predictions. Flux beyond 1.3x10 11 photons/s was measured up to 1300 eV, and thus over nearly the complete energy range covered by this high-brilliance grating, with a maximum of 1.6x10 11 photons/s between 800 and 1100 eV. First results from polarization measurements confirm a polarization above 99.7% for both linearly and circularly polarized modes at low energies. Circular dichroism experiments indicate a circular polarization beyond 90% at the Fe L 2 /L 3 edge near 720 eV

    Full Text Available Background: The effects of Ramadan fasting on NAFLD are unknown and there are very limited studies have done in this area. Some nutritional and behavioral changes of fasting people in Ramadan can affect NAFLD. These include nutrition with high fat and calories, altering in weight and sleep and low physical activity. We decided to evaluate the effects of these changes on one of the important indicators of deterioration of NAFLD, ALT.Methods: Sixty patients with fatty liver disease performed two consecutive ALT exams before and after Ramadan month of whom finally 34 were fasting and 26 nonfasting. After collecting data they were divided in two groups of fasting and nonfasting and compared using SPSS software.Results: Mean ALT change from before to after Ramadan was higher and positive in fasting (+7.38±8.47 IU/L compared to nonfastng patients that was negative (-0.12±10.15 IU/L (P=0.002 and this change was mainly in patients who had fasted 21-30 days.Conclusion: Ramadan fasting may increase ALT. It is needed to perform more studies in patients with NAFLD during Ramadan fasting with larger sample size and in various conditions especially weight loss with patients’ education for observing dietary regimen.

    Background: Alanine Aminotransferase (ALT) is an enzyme found in Liver and indicates injury to Hepatocytes. It is influenced by various factors. The objectives of this study were to identify the correlates of ALT activity among healthy medical students of Army Medical College, National University of Sciences and Technology, aged 18-22 years. This was to establish the mean ALT levels of the students and compare them with those in various parts of the world and observe various correlations that exist and factors that may influence ALT levels. Methods: This population included 143 volunteer students (93 men and 50 women) selected on the basis of negative answers to a detailed medical questionnaire including past medical history, drug and alcohol consumption, on the absence of clinical signs of liver disease, on the negativity of serological testing for Hepatitis B and C virus. Results: The mean ALT level of the entire population was 28.7 IU/L. A major sex-difference in ALT value was observed, the mean ALT value being higher in men than in women (32.1+- 21.7 vs. 22.6 +- 9.7 IU/L, p<0.004). According to WHO criteria for Asians, normal BMI was taken from 18.5-23.0 Kg/m/sup 2/. There was a positive significant correlation between serum ALT level and BMI (p<0.002). ALT level strongly correlates with body mass index and gender. There was no significant variation in ALT levels among Punjabis and Sindhis, Balochis, Pathans, and Kashmiris. Conclusion: We suggest the need of taking into account these parameters in a clinical interpretation of ALT level. (author)

    Directory of Open Access Journals (Sweden)

    Eun Young Yu

    2015-10-01

    Full Text Available A subset of human cancer cells uses a specialized, aberrant recombination pathway known as ALT to maintain telomeres, which in these cells are characterized by complex aberrations including length heterogeneity, high levels of unpaired C-strand, and accumulation of extra-chromosomal telomere repeats (ECTR. These phenotypes have not been recapitulated in any standard budding or fission yeast mutant. We found that eliminating Ku70 or Ku80 in the yeast-like fungus Ustilago maydis results initially in all the characteristic telomere aberrations of ALT cancer cells, including C-circles, a highly specific marker of ALT. Subsequently the ku mutants experience permanent G2 cell cycle arrest, accompanied by loss of telomere repeats from chromosome ends and even more drastic accumulation of very short ECTRs (vsECTRs. The deletion of atr1 or chk1 rescued the lethality of the ku mutant, and "trapped" the telomere aberrations in the early ALT-like stage. Telomere abnormalities are telomerase-independent, but dramatically suppressed by deletion of mre11 or blm, suggesting major roles for these factors in the induction of the ALT pathway. In contrast, removal of other DNA damage response and repair factors such as Rad51 has disparate effects on the ALT phenotypes, suggesting that these factors process ALT intermediates or products. Notably, the antagonism of Ku and Mre11 in the induction of ALT is reminiscent of their roles in DSB resection, in which Blm is also known to play a key role. We suggest that an aberrant resection reaction may constitute an early trigger for ALT telomeres, and that the outcomes of ALT are distinct from DSB because of the unique telomere nucleoprotein structure.

    Nanocapsules with diameter around 100 nm based on a natural polymer (chitosan) and a synthetic polymer poly(vinyl acetate- alt-maleic anhydride) [poly(MAVA)] by interfacial condensation method were prepared. The present study proposes a new type of biocompatible nanocapsules based on poly(vinyl acetate- alt-maleic anhydride-chitosan) (MCS) able to become a reliable support for inclusion and release of drugs. The spherical shape of the nanocapsules was evidenced by scanning electron microscopy. Nanocapsules presented a good Norfloxacin loading and release capacity. Haemocompatibility tests have demonstrated that the nanocapsules present a low toxicity and a good compatibility with sanguine medium. The biocompatibility properties of the nanocapsules after their intraperitoneal administration in rats were evidenced by histopathological examination of different organs (brain, liver, kidney, and lung). The results are encouraging and the nanocapsules can be used as controlled drug delivery systems.

    Installation of a large toroidal belt pump limiter, Advanced Limiter Test II (ALT-II), on the TEXTOR tokamak at Juelich, FRG is anticipated for early 1986. This paper discusses the preliminary mechanical design and materials considerations undertaken as part of the feasibility study phase for ALT-II. Since the actively cooled limiter blade is the component in direct contact with the plasma edge, and thus subject to the severe plasma environment, most preliminary design efforts have concentrated on analysis of the blade. The screening process which led to the recommended preliminary design consisting of a dispersion strenghthened copper or OFHC copper cover plate over an austenitic stainless steel base plate is discussed. A 1 to 3 mm thick low atomic number coating consisting of a graded plasma-sprayed Silicon Carbide-Aluminium composite is recommended subject to further experiment and evaluation. Thermal-hydraulic and stress analyses of the limiter blade are also discussed. (orig.)

We investigated the antioxidant and anti-fatigue activities of P. alte-lobatum in exercised rats. Levels of polyphenols, flavonoids and polysaccharides and 2,2-diphenyl-1-picrylhydrazyl (DPPH free-radical scavenging activity were measured in extracts of P. alte-lobatum (EPA. Sprague-Dawley rats were randomly divided into four groups for 8-week treatment with vehicle (control and low-, medium-, and high-dose EPA (LEPA, MEPA, HEPA; 0, 75, 150, and 375 mg/kg/day, respectively. Exercise performance was evaluated by exhaustive treadmill exercise time and by changes in body composition and biochemical variables at the end of the experiment. EPA contained polyphenols, flavonoids and polysaccharides, with polysaccharide content at least 26 times greater than that of polyphenols and flavonoids. Trend analysis revealed that EPA dose-dependently scavenged DPPH free radicals. EPA treatment dose-dependently increased endurance running time to exhaustion and superoxide dismutase activity and total antioxidant ability of blood. EPA dose-dependently decreased serum urea nitrogen and malondialdehyde levels after exercise. Hepatic glycogen content, an important energy source for exercise, was significantly increased with EPA treatment. EPA could be a potential agent with an anti-fatigue pharmacological function.

  12. Cueing musical emotions: An empirical analysis of 24-piece sets by Bach and Chopin documents parallels with emotional speech.

    Poon, Matthew; Schutz, Michael

    2015-01-01

    Acoustic cues such as pitch height and timing are effective at communicating emotion in both music and speech. Numerous experiments altering musical passages have shown that higher and faster melodies generally sound "happier" than lower and slower melodies, findings consistent with corpus analyses of emotional speech. However, equivalent corpus analyses of complex time-varying cues in music are less common, due in part to the challenges of assembling an appropriate corpus. Here, we describe a novel, score-based exploration of the use of pitch height and timing in a set of "balanced" major and minor key compositions. Our analysis included all 24 Preludes and 24 Fugues from Bach's Well-Tempered Clavier (book 1), as well as all 24 of Chopin's Preludes for piano. These three sets are balanced with respect to both modality (major/minor) and key chroma ("A," "B," "C," etc.). Consistent with predictions derived from speech, we found major-key (nominally "happy") pieces to be two semitones higher in pitch height and 29% faster than minor-key (nominally "sad") pieces. This demonstrates that our balanced corpus of major and minor key pieces uses low-level acoustic cues for emotion in a manner consistent with speech. A series of post hoc analyses illustrate interesting trade-offs, with sets featuring greater emphasis on timing distinctions between modalities exhibiting the least pitch distinction, and vice-versa. We discuss these findings in the broader context of speech-music research, as well as recent scholarship exploring the historical evolution of cue use in Western music.

    Full Text Available ObjectiveTo investigate the time for liver stiffness measurement (LSM to become stable in chronic hepatitis C (CHC patients with elevated alanine aminotransferase (ALT levels after ALT normalization due to antiviral therapy. MethodsCHC patients who sought initial treatment at Peking University People′s Hospital were screened for elevated ALT levels from May 2011. Liver stiffness was determined by FibroScan. A total of 29 patients had been included in the study by September 2012, who were followed up regularly after antiviral treatment. ALT tests were repeated every four weeks and LSM every eight weeks until their medians did not change significantly. Comparisons of matched data at two adjacent time points were made with the non-parametric Wilcoxon test, while multiple comparisons of repeated measurements were performed using Bonferroni correction. Correlation between two variables was analyzed with the Spearman rank test. ResultsPatients were followed up until 24 weeks after antiviral treatment, and 24 patients were included in analysis. The median ALT levels were 64, 26, 21, 20, and 22 U/L at baseline and 4, 8, 12, and 24 weeks, respectively (P= 0.000, 0.006, 0.337, and 0.109 for comparisons between two adjacent values. ALT decreased significantly below 1 ULN at 4 weeks after antiviral therapy and stabilized at 8 weeks. The median LSM values were 8.7, 7.8, 6.8, and 6.7 kPa at baseline and 8, 16, and 24 weeks, respectively (P= 0.009, 0.001, and 0188 for comparisons between two adjacent values. LSM decreased significantly within 16 weeks after antiviral therapy and stabilized afterwards. LSM stabilized 12 weeks after ALT normalization. ConclusionLSM becomes stable in CHC patients with elevated ALT levels three months after ALT normalization due to antiviral therapy.

    Immortalized and cancer cells maintain their telomeres by activation of a telomere maintenance mechanism (TMM). In approximately 85% of cancers telomerase is activated (TA) but in some tumours, in particular sarcomas, an alternative lengthening of telomeres (ALT) pathway is used. Liposarcomas are the most common soft-tissue sarcoma in adults and they activate ALT or telomerase with equal frequency, however no TMM has been identified in approximately 50% of liposarcomas. In our study, we have shown that instability at the minisatellite MS32, usually associated with ALT activation, aids the identification of liposarcomas that have recombination-like activity at telomeres in absence of ALT associated PML-bodies (APBs). Furthermore, using single molecule telomere analysis, we have detected complex telomere mutations directly in ALT positive liposarcomas and interestingly in some liposarcomas with an unknown TMM but high MS32 instability. We have shown by sequence analysis that some of these complex telomere mutations must arise by an inter-molecular recombination-like process rather than by deletion caused by t-loop excision or by unequal telomere-sister-chromatid-exchange (T-SCE), which is known to be elevated in ALT cell lines. Preliminary evidence also suggests that inter-molecular recombination events may be processed differently in liposarcomas with APBs compared to those without. In conclusion, we have shown for the first time, that some telomerase negative liposarcomas without APBs have other features associated with ALT, indicating that the incidence of ALT in these tumours has previously been under-estimated. This has major implications for the use of cancer treatments targeted at TMMs. (c) 2008 Wiley-Liss, Inc.

    Full Text Available Background: In recent years the ratio of aspartate aminotransferase (AST to alanine aminotransferase (ALT in patients of chronic liver disease (CLD of various origins has gained much attention. This variable is readily available, easy to interpret, and inexpensive and the clinical utility of the AST/ALT ratio in the diagnostic workup of patients with CLD is quite promising. Objective: The present study was designed to find out the link between aminotransferase (AST/ALT ratio with commonly measured biochemical parameters of liver function tests in CLD of viral origin. Materials and method: This cross sectional study was carried out in the department of Biochemistry, Sir Salimullah Medical College, Dhaka, Bangladesh. Forty four biopsy proven diagnosed subjects of chronic viral hepatitis without cirrhosis of both sex were selected purposively. With aseptic precaution 5 mL venous blood was collected from each subject and common liver function tests (serum AST, ALT, AST/ALT ratio, alkaline phosphatase, total bilirubin, serum total protein, serum albumin, serum globulin, serum albumin/globulin ratio, prothrombin time and viral serology (HBsAg, Anti HDV antibody, Anti HCV antibody were performed. Data were analyzed by SPSS version 19 for Windows. Pearson’s correlation test was done to determine association between AST/ALT with other biochemical parameters. Results: Mean(±SD age of the study subjects was 32.55±10.55 years (range 20-50 years with 48 (77.7% male and 14 (22.6% female subjects. Pearson’s correlation test was done between AST to ALT ratio with other biochemical parameters and prothrombin time showed significant positive correlation (p <0.01. Conclusion: In our study we found significant positive correlation between AST/ALT with prothrombin time in CLD subjects without cirrhosis.

    Trace element contents in authigenic pyrite were investigated in relationship to the geochemistry of host rocks in a 160 m deep drilling at Büdesheimer Bach (Prümer Mulde, Germany), in order to put constrains on possible changes in depositional conditions and seawater composition related to the Kellwasser events (Frasnian/Fammenian transition). The approach is based on the observation that the trace element pattern of authigenic pyrite is controlled by genetic conditions (Stüben et al., 2002) and that the content of elements with generally high degree of pyritization (DTMP, degree of trace metal pyritization, like As, Mo, Co, Ni, etc.) depends on their availability at the site of pyrite formation (e.g. Huerta-Diaz and Morse, 1992). The distribution of trace elements in the bulk rock essentially reflects mineralogical composition and redox conditions which are mainly controlled by the flux of organic matter entering the sediment. The lower and upper Kellwasser horizons are marked by an increase in carbonate and organic carbon content (up to 2%), coupled with an increase in the degree of pyritization of Fe (DOP: 0.4-0.8), indicating a change from normal marine to suboxic/anoxic conditions. A simultaneous drop in the Ba content of the host lithology, which usually is used as a proxy for paleoproductivity, can be explained by the removal of Ba dissolved in pore water under anoxic conditions (McManus et al., 1998). While low in the host rock, the Ba content of authigenic pyrite is high in these horizons, suggesting that pyrite may preserve the initial composition of pore water even for some elements with generally low DTMP, like Ba. Consequently, Ba content in pyrite may serve as indicator for productivity even when the Ba content of sediment can not be used due to its poor preservation. During these anoxic episodes also a significant increase in the content of As, U, V was registered in pyrite. Opposite to these, others like Ni, Co, Ag show a decrease in their

    In Stockholm, Sweden, the majority of pregnant women positive for hepatitis B surface antigen (HBsAg) are hepatitis Be antigen (HBeAg) negative. Newborns to HBeAg positive mothers receive vaccination and hepatitis B immunoglobulin (HBIg). Newborns to HBeAg negative mothers receive vaccine and HBIg only if the mothers have elevated ALT levels. The aim of this study was to retrospectively evaluate ALT levels as a surrogate marker for HBV DNA levels in HBeAg negative carrier mothers. Altogether 8947 pregnant women were screened for HBV markers from 1999 to 2001 at the Virology Department, Karolinska Hospital. Among mothers screened 192 tested positive for HBsAg (2.2%). 13 of these samples could not be retrieved. Of the remaining 179 sera, 8 (4%) tested positive for HBeAg and 171 (95.5%) were HBeAg negative. Among the HBeAg negative mothers, 9 had HBV DNA levels > 10(5) copies/ml, and of these 7 had normal ALT levels indicating low sensitivity of an elevated ALT level as a surrogate marker for high HBV DNA level. Furthermore, no correlation was found between ALT and HBV DNA levels. Hence, it is concluded that the use of ALT as a surrogate marker for high viral replication in HBeAg negative mothers could be questioned.

    Childhood obesity is a risk factor for non-alcoholic fatty liver disease and poses important public health issues for children. Racial differences in alanine aminotransferase (ALT) levels among children have not been described. This study aimed to identify racial differences in upper limit normal (ULN) ALT levels and evaluate the effect of obesity on elevated levels in children without other metabolic risk factors. National Health and Nutrition Examination Surveys and clinical data from the Loyola University Health System were used to determine ULN ALT by race and gender. Quantile regression was used to evaluate the impact of obesity on elevated ALT and to identify potential risk factors for ALT above the ULN. Upper limit normal (ULN) ALT was approximately 28.0 and 21.0-24.0 U/L for boys and girls, respectively. No significant difference in ULN ALT across race was observed. Obesity was significantly associated with elevated ALT; obese children with elevated ALT had values 10 U/L higher than normal-weight children. Racial differences in ALT levels among adults are not evident in children. Obesity, in the absence of metabolic risk factors and other causes of liver disease, is associated with elevated ALT, providing evidence against the concept of healthy obesity in children. © 2016 World Obesity Federation.

    2016-03-01

    Este artículo discute la obra de Crispín Portugal (1976-2007, un escritor alteño, en el contexto de la lucha contra la pobreza y el racismo que enfrentan a las ciudades de El Alto y La Paz, y del movimiento en contra del mercado  que comenzó en Argentina produciendo libros con tapas de cartón compradas a los cartoneros. Portugal y otros escritores indígenas iniciaron un proyecto editorial llamado Yerba Mala Cartonera, que cuenta con su propio blog, para diseminar la literatura boliviana que no cuenta con otros medios de difusión. A través de la revisión de un cuento de Portugal (Almha La Vengadora que describe a una chola luchadora de El Alto cuyo nombre en el cuadrilátero es “la vengadora”, este trabajo plantea la configuración de un indigenismo alteño de neovanguardia equiparable al vanguardismo de Gamaliel Churata.  Con este propósito, presta especial atención a El Alto –la ciudad indígena más grande de Latinoamérica- situándolo como escenario clave para el desarrollo de una neovanguardia que se alimenta del neoliberalismo fallido para configurar una propuesta de modernidad que recupera el pasado indígena aymara para inventar otras formas de futuro.

  4. Wolfgang Bargmann (1906-1978) and Heinrich von Hayek (1900-1969): careers in anatomy continuing through German National Socialism to postwar leadership.

    None of the existing studies on the history of anatomy in National Socialism (NS) has yet explored the careers of those younger anatomists, whose professional development continued through NS times and who attained prominence in postwar German and Austrian anatomy. As they became modern anatomists' teachers and role models, the revelation that men like Wolfgang Bargmann and Heinrich von Hayek had used bodies of the executed for research in their early careers has recently led to some consternation. This study contributes to the analysis of the moral challenges inherent to a science that relies on work with "material" from human bodies and its interaction with its political environment. The results reveal that Bargmann and Hayek behaved like most other anatomists at the time, in that they used bodies of the executed for research and in that they joined the NS party or other NS political groups. As ambitious and successful young anatomists they may have felt that an early joining of NS affiliations was inevitable for the advancement of their careers. They and most of their colleagues became in some measure complicit with the NS regime. The complicated biographical realities of such luminous postwar figures as Bargmann and Hayek should lead modern anatomists to the questioning of their own ethical and political decisions in politically less demanding times.

    2018-01-01

    This paper aims to investigate the character and etiological basis of German poet Johann Wolfgang von Goethe's mental disorder. From 1898, German neuropsychiatrist Paul Julius Möbius developed the hypothesis that Goethe's work provided several hints for the notion that the German poet suffered from a distinct bipolar disorder. The paper investigates Möbius's psychopathographic study on Goethe and his hypothesis of a mood periodicity in Goethe against the mirror of modern concepts. Möbius came to the conclusion that Goethe's illness was bipolar in character and became visible at intervals of seven years and lasted for about two years. The majority of Möbius's contemporary psychiatric colleagues (Emil Kraepelin, Max Isserlin, Ernst Kretschmer, Josef Breuer) supported this view which has still not been convincingly challenged. In present-day terms, Möbius's hypothesis can be best mirrored as a subclinical foundation of mood disorder. Furthermore, with his extensive study, Möbius disproved the common notion that Goethe had suffered from an illness as the result of a syphilitic infection.

    Aims The ratio of aspartate aminotransferase (AST) to alanine aminotransferase (ALT) is of great interest as a possible novel marker of metabolic syndrome. However, longitudinal studies emphasizing the incremental predictive value of the AST-to-ALT ratio in diagnosing individuals at higher risk of developing metabolic syndrome are very scarce. Therefore, our study aimed to evaluate the AST-to-ALT ratio as an incremental predictor of new onset metabolic syndrome in a population-based cohort study. Material and Methods The population-based cohort study included 2276 adults (903 men and 1373 women) aged 40–70 years, who participated from 2005–2008 (baseline) without metabolic syndrome and were followed up from 2008–2011. Metabolic syndrome was defined according to the harmonized definition of metabolic syndrome. Serum concentrations of AST and ALT were determined by enzymatic methods. Results During an average follow-up period of 2.6-years, 395 individuals (17.4%) developed metabolic syndrome. In a multivariable adjusted model, the odds ratio (95% confidence interval) for new onset of metabolic syndrome, comparing the fourth quartile to the first quartile of the AST-to-ALT ratio, was 0.598 (0.422–0.853). The AST-to-ALT ratio also improved the area under the receiver operating characteristic curve (AUC) for predicting new cases of metabolic syndrome (0.715 vs. 0.732, P = 0.004). The net reclassification improvement of prediction models including the AST-to-ALT ratio was 0.23 (95% CI: 0.124–0.337, Pmetabolic syndrome and had incremental predictive value for incident metabolic syndrome.

    The ubiquitously present spores of Alternaria alternata can spoil a wide variety of foodstuffs, including a variety of fruits belonging to the Citrus genus. The major allergenic protein of A. alternata, Alt a 1, is a species-specific molecular marker that has been strongly associated with allergenicity and phytopathogenicity of this fungal species. This study aimed to evaluate the potential of the detection of Alt a 1 as a reliable indicator of A. alternata contamination in citrus fruits. To accomplish this aim, sixty oranges were artificially infected with a spore suspension of A. alternata. Internal fruit material was collected at different incubation times (one, two and three weeks after the fungal inoculation) and used for both total RNA extraction and protein extraction. Alt a 1 detection was then performed by polymerase chain reaction (PCR) amplification using Alt a 1 specific primers and by enzyme-linked immunosorbent assay (ELISA). The experimental model presented in this work was effective to simulate the typical Alternaria black rot phenotype and its progression. Although both PCR and ELISA techniques have been successfully carried out for detecting Alt a 1 allergen in A. alternata infected oranges, the PCR method was found to be more sensitive than ELISA. Nevertheless, ELISA results were highly valuable to demonstrate that considerable amounts of Alt a 1 are produced during A. alternata fruit infection process, corroborating the recently proposed hypothesis that this protein plays a role in the pathogenicity and virulence of Alternaria species. Such evidence suggests that the detection of Alt a 1 by PCR-based assay may be used as a specific indicator of the presence of pathogenic and allergenic fungal species, A. alternata, in fruits. This knowledge can be employed to control the fungal infection and mitigate agricultural losses as well as human exposure to A. alternata allergens and toxins. Copyright © 2017 Elsevier B.V.

    A field survey was carried out to record plant species climbed by Ephedra alte in certain parts of Jordan during 2008-2010. Forty species of shrubs, ornamental, fruit, and forest trees belonging to 24 plant families suffered from the climbing habit of E. alte. Growth of host plants was adversely affected by E. alte growth that extended over their vegetation. In addition to its possible competition for water and nutrients, the extensive growth it forms over host species prevents photosynthesis, smothers growth and makes plants die underneath the extensive cover. However, E. alte did not climb all plant species, indicating a host preference range. Damaged fruit trees included Amygdalus communis, Citrus aurantifolia, Ficus carica, Olea europaea, Opuntia ficus-indica, and Punica granatum. Forestry species that were adversely affected included Acacia cyanophylla, Ceratonia siliqua, Crataegus azarolus, Cupressus sempervirens, Pinus halepensis, Pistacia atlantica, Pistacia palaestina, Quercus coccifera, Quercus infectoria, Retama raetam, Rhamnus palaestina, Rhus tripartita, and Zizyphus spina-christi. Woody ornamentals attacked were Ailanthus altissima, Hedera helix, Jasminum fruticans, Jasminum grandiflorum, Nerium oleander, and Pyracantha coccinea. Results indicated that E. alte is a strong competitive for light and can completely smother plants supporting its growth. A. communis, F. carica, R. palaestina, and C. azarolus were most frequently attacked.

    2005-02-01

    A gene for the Alternaria major allergen, Alt a 1, was amplified from 52 species of Alternaria and related genera, and sequence information was used for phylogenetic study. Alt a 1 gene sequences evolved 3.8 times faster and contained 3.5 times more parsimony-informative sites than glyceraldehyde-3-phosphate dehydrogenase (gpd) sequences. Analyses of Alt a 1 gene and gpd exon sequences strongly supported grouping of Alternaria spp. and related taxa into several species-groups described in previous studies, especially the infectoria, alternata, porri, brassicicola, and radicina species-groups and the Embellisia group. The sonchi species-group was newly suggested in this study. Monophyly of the Nimbya group was moderately supported, and monophyly of the Ulocladium group was weakly supported. Relationships among species-groups and among closely related species of the same species-group were not fully resolved. However, higher resolution could be obtained using Alt a 1 sequences or a combined dataset than using gpd sequences alone. Despite high levels of variation in amino acid sequences, results of in silico prediction of protein secondary structure for Alt a 1 demonstrated a high degree of structural similarity for most of the species suggesting a conservation of function.

    To estimate treatment effects of Shuxuetong injection on abnormal changes on ALT index, that is, to explore whether the Shuxuetong injection harms liver function in clinical settings and to provide clinical guidance for its safe application. Clinical information of traditional Chinese medicine (TCM) injections is gathered from hospital information system (HIS) of eighteen general hospitals. This is a retrospective cohort study, using abnormal changes in ALT index as an outcome. A large number of confounding biases are taken into account through the generalized boosted models (GBM) and multiple logistic regression model (MLRM) to estimate the treatment effects of Shuxuetong injections on abnormal changes in ALT index and to explore possible influencing factors. The advantages and process of application of GBM has been demonstrated with examples which eliminate the biases from most confounding variables between groups. This serves to modify the estimation of treatment effects of Shuxuetong injection on ALT index making the results more reliable. Based on large scale clinical observational data from HIS database, significant effects of Shuxuetong injection on abnormal changes in ALT have not been found.

  14. The medical laboratory issues about recommendation on uniform cutoff values of “normal” ALT in the ACG guidelines

    Directory of Open Access Journals (Sweden)

    YU Qian

    2018-01-01

    Full Text Available In the recent American clinical guidelines dealing with laboratory tests for evaluation of liver disease, the American College of Gastroenterology (ACG recommends ALT upper reference limits of 33 U/L for males and 25 U/L for females respectively, and that individuals with ALT above these “normal” cutoffs should be further investigated. Considering the differences between laboratory assays measuring ALT in our country, the standardization of methods and the consistency of results can not be completely ensured. The uniform “normal” range of ALT recommended by the ACG guidelines is largely based on findings from foreign studies and may not be suitable to Chinese population. On the other hand, reference upper/lower limits should not simply be equated with clinical decision thresholds. However, due to improper application of the related concepts of the above medical laboratory issues, simply recommending the uniform reference range of the ALT may lead to overdiagnosis and unnecessary follow-up examinations.

    Full Text Available Background/Aims: ALT1 is a novel long non-coding RNA derived from the alternatively spliced transcript of the deleted in lymphocytic leukemia 2 (DLEU2. To date, ALT1 biological roles in human vascular endothelial cells have not been reported. Methods: ALT1 was knocked down by siRNAs. Cell proliferation was analyzed by cck-8. The existence and sequence of human ALT1 were identified by 3’ rapid amplification of cDNA ends. The interaction between lncRNA and proteins was analyzed by RNA-Protein pull down assay, RNA immunoprecipitation, and mass spectrometry analysis. Results: ALT1 was expressed in human umbilical vein endothelial cells (HUVECs. The expression of ALT1 was significantly downregulated in contact-inhibited HUVECs and in hypoxia-induced, growth-arrested HUVECs. Knocking down of ALT1 inhibited the proliferation of HUVECs by G0/G1 cell cycle arrest. We observed that angiotensin converting enzyme Ⅱ(ACE2 was a direct target gene of ALT1. Knocking-down of ALT1 or its target gene ACE2 could efficiently decrease the expression of cyclin D1 via the enhanced ubiquitination and degradation, in which HIF-1α and protein von Hippel-Lindau (pVHL might be involved. Conclusion: The results suggested the human long non-coding RNA ALT1 is a novel regulator for cell cycle of HUVECs via ACE2 and cyclin D1 pathway.

    Full Text Available We compute the contribution from the longitudinally polarized proton to the twist-3 double-spin asymmetry ALT in inclusive (light hadron production from proton–proton collisions, i.e., p↑p→→hX. We show that using the relevant QCD equation-of-motion relation and Lorentz invariance relation allows one to eliminate the twist-3 quark-gluon correlator (associated with the longitudinally polarized proton in favor of one-variable twist-3 quark distributions and the (twist-2 transversity parton density. Including this result with the twist-3 pieces associated with the transversely polarized proton and unpolarized final-state hadron (which have already been calculated in the literature, we now have the complete leading-order cross section for this process.

  19. Comparing the characteristics of highly cited titles and highly alted titles

    Energy Technology Data Exchange (ETDEWEB)

    2016-07-01

    This study examines differences in the types of titles for articles that show high altmetric activity (highly alted articles) versus highly cited articles. This work expands on previous research on document titles in combination with a grounded theory approach to develop a codebook in which articles were manually coded based on 11 characteristics. The results show that there are differences and similarities in titles across many of the examined characteristics; highly cited titles and highly mentioned titles on Wikipedia have some similar characteristics such as they have the the highest percentage of substantive words; in addition, there are no or very few titles referencing outside or with humor/lightness on both platforms. Twitter and Facebook also showed some similarities having the highest percentage of humorous/light titles and lowest percentage of substantive words in their titles. (Author)

    All major program milestones have been met and the program is executing within budget. The ALT 370 program achieved Phase 6.4 authorization in February of this year. Five component Final Design Reviews (FDRs) have been completed, indicating progress in finalizing the design and development phase of the program. A series of ground-based qualification activities have demonstrated that designs are meeting functional requirements. The first fully functional flight test, FCET-53, demonstrated end-to-end performance in normal flight environments in February. Similarly, groundbased nuclear safety and hostile environments testing indicates that the design meets requirements in these stringent environments. The first in a series of hostile blast tests was successfully conducted in April.

  2. On the hydrology and fluvial sediment transport of the proglacial river Riffler Bach (Weißseeferner, Ötztal Alps, Tyrol)

    2013-04-01

    The hydrology of proglacial rivers is strongly affected by glacier melting. With ongoing glacier retreat the proportion of glacier meltwater in proglacial rivers is declining over longer time periods. Snow melt or rain fall events will play a more important role as water source. Due to glacial erosion the glacier system is also an important player in the orchestra of sediment sources/processes contributing to proglacial sediment budgets. The consequence of increasing deglaciation is a growing importance of other sediment sources/processes, mainly known as paraglacial, for sediment budgets in glacier forefields. The sediment export out of proglacial areas is mainly done by solid river load. Knowledge on the quantity of the exported sediments is important for reservoir management and torrent control. In order to measure fluvial sediment transport in the catchment area of the Gepatsch reservoir in the Ötztal Alps (Tyrol/Austria) we have installed a gauging station at the proglacial river Riffler Bach in June 2012. The catchment area of this station is about 20 km² with an altitudinal range from 1929 m to 3518 m. The higher altitudes in the southern part of the area are covered by the glacier Weißseeferner. Our station is equipped with an automatic water sampler (AWS 2002) and probes for water level, turbidity and electrical conductivity. All parameters are recorded in 5-15 minute intervals during the ablation period. Discharge is measured with current meters during wadable stages and salt dilution during higher floods. Bed load is measured concurrent to discharge measurements using a Helley-Smith sampler. In 2012, 189 water samples were taken and will be analyzed for suspended sediment concentration and ion content. Additionally, the grain size distribution will be determined using a Malvern laser diffractometer. Rating-curves will be used to calculate discharge from stage recordings. Solid load of the Riffler Bach will be quantified using the discharge data and

    Full Text Available Background: We analyzed telomere maintenance mechanisms (TMMs in lymph node samples from HL patients treated with standard therapy. The TMMs correlated with clinical outcomes of patients. Materials and Methods: Lymph node biopsies obtained from 38 HL patients and 24 patients with lymphadenitis were included in this study. Seven HL cell lines were used as in vitro models. Telomerase activity (TA was assessed by TRAP assay and verified through hTERT immunofluorescence expression; alternative telomere lengthening (ALT was also assessed, along with EBV status. Results: Both TA and ALT mechanisms were present in HL lymph nodes. Our findings were reproduced in HL cell lines. The highest levels of TA were expressed in CD30−/CD15− cells. Small cells were identified with ALT and TA. Hodgkin and Reed Sternberg cells contained high levels of PML bodies, but had very low hTERT expression. There was a significant correlation between overall survival (p < 10−3, event-free survival (p < 10−4, and freedom from progression (p < 10−3 and the presence of an ALT profile in lymph nodes of EBV+ patients. Conclusion: The presence of both types of TMMs in HL lymph nodes and in HL cell lines has not previously been reported. TMMs correlate with the treatment outcome of EBV+ HL patients.

    Calcium oxalate (CaOx) particles exhibiting different shapes and phase structures were fabricated by a simple precipitation reaction of sodium oxalate with calcium chloride in the absence and presence of poly-(styrene-alt-maleic acid) (PSMA) as a crystal modifier at room temperature. The as-obtained products were characterized with scanning electron microscopy (SEM) and X-ray diffraction (XRD). The effects of reaction conditions including pH, [Ca 2+ ]/[C 2 O 4 2- ] ratio and concentration of PSMA and CaC 2 O 4 on the crystal forms and morphologies of the as-obtained calcium oxalate were investigated. The results show that various crystal morphologies of calcium oxalate, such as parallelograms, plates, spheres, bipyramids etc. can be obtained depending on the experimental conditions. Higher polymer concentration favors formation of the metastable calcium oxalate dihydrate (COD) crystals. Lower pH is beneficial to the formation of plate-like CaOx crystals. Especially, the monodispersed parallelogram-like CaOx crystals can be produced by PSMA as an additive at pH 2. PSMA may act as a good inhibitor for urolithiasis since it induces the formation of COD and reduces the particle size of CaOx. This research may provide new insight into the morphological control of CaOx particles and the prevention of urolithiasis

    On the TEXTOR pump limiter ALT-I conductance measurements for the backstreaming of gas from the pump limiter vessel through the pump limiter entrance have been performed. In these experiments neutral gas has been injected into the pump limiter plenum during a short pulse. The influence of the instreaming plasma results in a reduction of the conductance of the outstreaming gas. For helium the conductance is reduced to about 40% of the molecular conductance when a plasma flux of 0.8 A/cm 2 (T e =T i =11 eV) is streaming into the pump limiter throat. The reduction of the conductance for backstreaming hydrogen and deuterium under the same plasma conditions is smaller; about 70% of the molecular conductance is obtained. This reduction can be explained by an increased recycling of ions which have been produced in the throat back to the neutralizer plate. The experimental results can be reproduced by Monte Carlo neutral transport code calculations if the recycling coefficient is about 0.85 for hydrogen and deuterium and about 0.95 for helium ions. Processes causing these high recycling coefficients are discussed and their influence is estimated. (orig.)

    To determine the prevalence and describe clinical characteristics of seizure disorders and epilepsy as causes of apparent life- threatening event (ALTE) in children admitted at the emergency and followed in a tertiary hospital. Cross-sectional study with prospective data collection using specific guidelines to determine the etiology of ALTE. During the study, 30 (4.2%) children admitted to the hospital had a diagnosis of ALTE. There was a predominance of males (73%) and term infants (70%). Neonatal neurological disorders and neuropsychomotor development delay were found respectively in 13.4% and 10% of the cases. Etiological investigation revealed that 50% of the cases were idiopathic, and 13.4% were caused by epilepsy or seizure disorders. Although all patients had recurrent ALTE events, epilepsy had not been previously suspected. Epilepsy should be included in the differential diagnosis of ALTE, particularly when events are recurrent.

    Full Text Available Twelve pesticides commonly used in citrus in Spain were tested on adults of Aphytis melinus DeBach to determine their effects on parasitoid survival and fecundity, and the duration of the residue of each pesticide. Six of these pesticides were found to be harmless to moderately harmful to this parasitoid in a laboratory assay in closed Petri dishes: spinosad (bait formulation, azadirachtin, fenbutatin, fosetyl-Al, copper oxichloride, and mancozeb, with their scores on the reduction of beneficial capacity (RBC index being between 21.4 and 94.6% after one week. The other six pesticides classified as harmful were tested on citrus plants to study their persistence over time under greenhouse conditions: Pirimicarb, pyriproxifen, paraffinic oil, abamectin, chlorpyrifos, and lambda-cyhalothrin. Most of these products reduced their negative effect on adults of A. melinus between one and six weeks after treatment, although lambda-cyhalothrin was still harmful to parasitoids 11 weeks after application. This information can help growers and consultants to make decisions about pesticide selection and application timing in citrus in order to support IPM implementation when A. melinus is present.

    Direct arylation (DA) of 2-chlorothiophene and 2-chloro-3-hexylthiophene with 4,7-dibromo-2,1,3-benzothiadiazole is used to synthesize 4,7-bis(5-chloro-2-thienyl)-2,1,3-benzothiadiazole (TBTCl2) and 4,7-bis(5-chloro-4-hexyl-2-thienyl)-2,1,3-benzothiadiazole (DH-TBTCl2) in one step. Suitable conditions of the Suzuki polycondensations (SPC) of TBTCl2 and DH-TBTCl2 with the carbazole comonomer CbzPBE2 are established, furnishing PCDTBT and P(Cbz-alt-TBT) with high molecular weight and yield. Compared with control samples made from the corresponding dibromides, high-temperature NMR and UV-vis spectroscopy indicate similar properties for PCDTBT but an increased content of Cbz-Cbz homocouplings for P(Cbz-alt-TBT). © 2014 WILEY-VCH Verlag GmbH & Co.

    Background/ Aims: Despite the existence of an easy tool to diagnose biliary tract disease as an etiology for acute pancreatitis (AP), the sensitivity of abdominal ultrasound is around 80%, which can be even lower in certain conditions. We have retrospectively reviewed data of 146 patients admitted for acute pancreatitis between 1999 and 2013. Bivariate analysis for clinical and biochemical variables was performed with respect to etiology of AP (biliary versus non-biliary). Multivariate analysis was performed by using binary logistic regression. There were 87 males (59.6%) and 59 females (40.4%), with a median age of 51. The etiology of acute pancreatitis was biliary in 71 patients (48.6%). Bivariate analysis found the following as significant association (p=0.001) with biliary pancreatitis: older age, female gender, and elevated AST, ALT. A binary logistic regression analysis identified as predictor factors for biliary etiology of acute pancreatitis: age OR = 1.031 (95% CI 1.004 - 1.059, p = 0.024), sex (female) OR = 2.34 (95% CI 1.022 - 5.359, p = 0.044) and ALT OR = 1.004 (95% CI 1.001 - 1.007, p =0.004). The two clinical scores included the three variables (A.S.ALT scores) in categorical format were generated and then checked with the ROC curves (areas under curve are 0.768 and 0.778). Age, female gender, and elevated ALT can help identifying cases with biliary etiology of acute pancreatitis.

    Full Text Available Meeting the increasing demand of clean water requires the development of novel efficient adsorbent materials for the removal of organic pollutants. In this context the use of natural, renewable sources is of special relevance and sepia melanin, thanks to its ability to bind a variety of organic and inorganic species, has already attracted interest for water purification. Here we describe the synthesis of a material obtained by the combination of sepia melanin and poly(ethylene-alt-maleic anhydride (P(E-alt-MA. Compared to sepia melanin, the resulting hybrid displays a high and fast adsorption efficiency towards methylene blue (a common industrial dye for a wide pH range (from pH 2 to 12 and under high ionic strength conditions. It is easily recovered after use and can be reused up to three times. Given the wide availability of sepia melanin and P(E-alt-MA, the synthesis of our hybrid is simple and affordable, making it suitable for industrial water purification purposes.

  17. Radiation induced, raft mediated grafting of styrene onto poly(ethylene-alt-tetrafluoroethylene) (ETFE)

    Complete text of publication follows. The development of cost-effective proton exchange membranes to replace the state-of-the-art and expensive perfluorinated membranes such as Nafion, Flemion, and Aciplex is one of the main challenges for commercialization of polymer electrolyte fuel cell technology. Recently, partially fluorinated poly(ethlyene-alt-tetrafluoroethylene) (ETFE) has been identified as a promising alternative base polymer film to prepare low-cost polymer electrolyte membranes because of its advantageous characters like superior mechanical properties and high resistance to radiation-induced damage. The radiation-induced grafting technique, based on the utilization of a polymer material such as ETFE in combination with further chemical modification steps (sulfonation) allows the functionalization of the base material and the introduction of the desired property (proton conductivity) for preparing a fuel cell membrane. However this simple conventional method suffers from one simple flaw: The molecular weight and the polydispersity of the grafted chains cannot be controlled. Predetermined molecular weights and low dispersities as well as homogeneous composition and desired architecture can be achieved by grafting of monomer onto base polymer under living/controlled free radical polymerization (CRP) conditions. Among the CRP methods, Reversible Addition Fragmentation-Chain Transfer (RAFT) is of particular interest as a very wide range of functional monomers can be polymerized in a controlled manner under non-demanding reaction conditions (e.g., tolerance to oxygen and low temperatures). The present study deals with the RAFT mediated radiation-induced (0.032 kGyh -1 , 60 Co) grafting of styrene on ETFE films followed by the sulfonation of the polystyrene grafts. The effect of monomer concentration, absorbed dose and RAFT agent concentration on the grafting were investigated. The synthesized films were characterized by ATR-FTIR, XPS, DSC and TGA methods

    2017-04-01

    To improve the understanding and interpretation of the depositional environment of a late Oligocene lacustrine organic rich oil-prone source rock succession, 2464 hand held (HH)-XRF measurements were made systematically on the 500 m long, continuous core from the fully cored Enreca-3 well. This core, drilled on the remote Bach Long Vi Island, northern Gulf of Tonkin, offshore Vietnam, represents a deep lake succession alternating between lacustrine pelagic dominated sediments interrupted by hyperpycnal turbidites, high density turbidites and debris flows [1, 2]. From a combined HH-XRF-XRD data set, multivariate data analysis and regression models are used to type the rock and to predict the XRD mineral composition based on HH-XRF composition. The rock types and the modelled mineral composition highlight the geochemical variations of the sediment and allows for direct comparison with sedimentological processes and facies changes. The modeling also depicts the cyclic alteration of rock types that are present on many different scales ranging from centimeters to hundreds of meters [1, 2]. The sedimentological and geochemical variations observed throughout the cored section reflects fluctuating paleoclimate, tectonism and hinterland condition controlling the depositional setting, which may provide a deeper understanding of the deposition of this and similar Paleogene syn-rift succession in the South China Sea region. It allows furthermore the development of a more generalized depositional model relevant for other deep-lacustrine syn-rift basins. [1] Petersen et al.

    We present a high-resolution stable isotope record based on bulk organic matter (δ13Corg) and fossil wood (δ13Cwood) originating from Oligocene deep lacustrine sediments cored on the Bach Long Vi Island, northern Gulf of Tonkin, offshore Vietnam. The sediments are exceptionally well preserved. They are thus excellently suited for a detailed stratigraphical analysis of the stable isotope record and as proxy for environmental and climatic changes within this period. The sediments were deposited in rapid subsiding, narrow and elongated fault-bound graben (Fyhn and Phach, 2015) and are represented by deep pelagic lacustrine organic-rich mud interrupted by numerous density-flow deposits (Hovikoski et al., 2016). The density-flow deposits contain abundant fragments of fossil wood. Therefore it was possible to obtain 262 coalified wood fragments together with 1063 bulk organic samples throughout the span of the core. This allowed to establish a high resolution stable C isotope record (δ13Corg and δ13Cwood). In addition 2464 handheld XRF determinations were carried out to further characterize the depositional environment (Rizzi et al., 2017). The organic carbon isotope trend from the 500 m core succession provides insight into the palaeoenvironmental changes of the lake during the Oligocene. Both, global and local factors control the δ13C variations. The aim of the study is to obtain pure global δ13Corg and δ13Cwood signals that would allow comparison of the studied sediments with coeval syn-rift successions in the South China Sea region and other parts of the world.

    Full Text Available An alternating copolymer of styrene and maleic acid (alt-PSMA differs from other polyanionic antiviral agents in that the negative charges of alt-PSMA are provided by carboxylic acid groups instead of sulfate or sulfonate moieties. We hypothesized that alt-PSMA would have activity against human immunodeficiency virus type 1 (HIV-1 comparable to other polyanions, such as the related compound, poly(sodium 4-styrene sulfonate (PSS. In assays using cell lines and primary immune cells, alt-PSMA was characterized by low cytotoxicity and effective inhibition of infection by HIV-1 BaL and IIIB as well as clinical isolates of subtypes A, B, and C. In mechanism of action assays, in which each compound was added to cells and subsequently removed prior to HIV-1 infection (“washout” assay, alt-PSMA caused no enhancement of infection, while PSS washout increased infection 70% above control levels. These studies demonstrate that alt-PSMA is an effective HIV-1 inhibitor with properties that warrant further investigation.

    2018-02-01

    Full Text Available This article considers the relationship between “hashtag activism” as it is currently being used by the alt-right and the tendency to draw on conspiracy theory that Richard Hofstadter identified as being prevalent among what he termed “pseudo-conservatives” half a century earlier. Both the alt-right and Hofstadter’s “pseudo-conservatives” can be characterised by a pronounced populist nationalism that understands its aims as protecting a particular way of life whilst drawing on an aggrieved sense of injustice at being conspired against by an unseen enemy. That this “enemy” is typically foreign in actuality or in spirit confirms the cultural dimension on which their politics is played out. It is argued here that this paranoid populist nationalism has been figuratively drawn upon in the rhetoric of Donald Trump and that this apparent openness to the “pseudo-conservative” discourse on nationalism has provided a bridging effect via which far right elements are seeking to normalize extremist viewpoints

    Full Text Available The determination of aminotranferases levels is very useful in the diagnosis of hepatopathies. In recent years, an elevated serum ALT level in blood donors has been associated with an increased risk of post-transfusion hepatitis (PTH. The purpose of the study was to research the factors associated with elevated ALT levels in a cohort of voluntary blood donors and to evaluate the relationship between increased ALT levels and the development of hepatitis C (HCV infection. 166 volunteer blood donors with elevated ALT at the time of their first donation were studied. All of the donors were questioned about previous hepatopathies, exposure to hepatitis, exposure to chemicals, use of medication or drugs, sexual behaviour, contact with blood or secretions and their intake of alcohol. Every three months, the serum levels of AST, ALT, alkaline phosphatase, gamma glutamyl transpeptidase, cholesterol, triglyceride and glycemia are assessed over a two year follow-up. The serum thyroid hormone levels as well as the presence of auto-antibodies were also measured. Abdominal ultrasound was performed in all patients with persistently elevated ALT or AST levels. A needle biopsy of liver was performed in 9 donors without definite diagnostic after medical investigation. The presence of anti-HCV antibodies in 116 donors were assayed again the first clinical evaluation. At the end of follow-up period (2 years later 71 donors were tested again for the presence of anti-HCV antibodies. None of donors resulted positive for hepatitis B or hepatitis C markers during the follow-up. Of the 116 donors, 101 (87% had persistently elevated ALT serum levels during the follow-up. Obesity and alcoholism were the principal conditions related to elevated ALT serum levels in 91/101 (90.1% donors. Hypertriglyceridemia, hypercholesterolemia, hypothyroidism and diabetes mellitus also were associated with increased ALT levels. Only 1/101 (0.9% had mild chronic active non A-G viral

    The hydrology of a proglacial river is strongly affected by glacier melting. Due to glacier retreat the effects of snow melt and rain storms will become more important in future decades. Additionally, the development of periglacial landscapes will play a more important role in the hydrology of proglacial rivers. The importance of paraglacial sediment sources in sediment budgets of glacier forefields is increasing, while the role of glacial erosion is declining. In two consecutive ablation seasons the fluvial sediment transport of the river Riffler Bach in the Kaunertal (Tyrol/Austria) was quantified. The catchment area of this station is 20 km² with an altitudinal range from 1929 m to 3518 m above msl. The "Weißseeferner" glacier (2.34 km² in 2012) is the greatest of the remaining glaciers. An automatic water sampler (AWS 2002) and a probe for water level were installed were installed at the outlet of the catchment. In order to calculate annual stage-discharge-relations, discharge (Q) was repeatedly measured with current meters. Concurrent to the discharge measurements bed load was collected using a portable Helley-Smith sampler. Bed load (BL) samples were weighted and sieved in the laboratory to gain annual bed load rating curves and grain size distributions. In 2012, 154 water samples were sampled during 7 periods and subsequently filtered to quantify suspended sediment concentrations (SSC). A Q-SSC-relation was calculated for every period due to the high variability in suspended sediment transport. In addition, the grain size distribution of the filtered material was determined by laser diffraction analysis. In 2013, the same procedure was performed for 232 water samples which were collected during 9 periods. Meteorological data were logged at the climate station "Weißsee", which is located in the centre of the study area. First results show a high variability of discharge and solid sediment transport both at the inter-annual as well as at the intra

    This study reports the preparation of novel polymeric nanocapsules based on a natural polymer, chitosan and a synthetic one, poly(N-vinylpyrrolidone-alt-itaconic anhydride) [(poly(NVPAI)] using an interfacial condensation technique. The infrared spectroscopy studies confirmed the crosslinking through the presence of amide bonds, formed between the two polymers chains. The diameter of nanocapsules was found in the range of 126–214 nm and it was determined by dynamic light scattering method. Morphological characterization demonstrated their nano size, the spherical shape of the nanocapsules and the formation of hollow particles. The nanocapsules presented good swelling capacity in aqueous solutions. 5-Fluorouracil (5-FU) loading and release capacity was studied, the processes being controlled by the drug diffusion through the polymeric membrane. The obtained results were encouraging, showing that 5-FU-loaded nanocapsules had 70 % higher apoptotic effect on A549 tumour cells than the drug in free state or mixed with the nanocapsules.

    Drug delivery systems based on polymer-drug conjugates give an improved treatment with lower toxicity or side effects and be used for the treatment of different diseases. Conjugates of biodegradable poly(styrene-alt-maleic anhydride) (PSMA), with a therapeutic agents such as amantadine hydrochloride, amlodipine, gabapentin, zonisamide and mesalamine, were afforded by the formation of the amide bonds of the amino drugs that reacted with the PSMA anhydride groups. The amounts of covalently conjugated drugs were determined by a {sup 1}H NMR spectroscopic method, and the in vitro release rate in buffer solution (pH 1.3) was studied at body temperature 37 Degree-Sign C. In kinetic studies, different dissolution models were examined to obtain drug release data and the collected data were well-fitted to the Korsmeyer-Peppas equation, revealing a dominant Fickian diffusion mechanism for drug release under the in vitro conditions.

Beethoven's music gives expression to "subjective" appeal, while Bach-type music, "subjective" soberness and reason in style. Karl Popper's "objective knowledge" is based on the partition of three worlds. As "world 3", it is characterized by objectivity, autonomy, shareability, etc. The isostructuralism and coherence in style between "objective knowledge" and Bach- type music provide an illustrative case for the commensuration of art and philosophy in certain sense through the reflective han- dling by Karl Popper.

    Apart from being a major pioneer of modern psychiatry, Johann Christian August Heinroth (1773 - 1843) is foremost famous as the first academic teacher, professor of this subject at Leipzig University. Despite his theoretical concepts being thoroughly investigated by medical historians, the fact that his scientific work also brought him in contact with Weimar poet and scientist Johann Wolfgang von Goethe (1749 - 1832) has up to now not been acknowledged. This paper analyses for the first time the manifold points of contact between the two geniuses. Starting off with a retrospective on Goethe's relationship towards psychiatry in his day, this paper investigates the mutual interconnections and influences between the two. This is achieved by an analysis of yet unknown primary sources as well as Goethe's literary and scientific works. A main emphasis is also placed on Heinroth's Textbook of Anthropology of 1822 in which the psychiatrist laid out his understanding of 'relational thinking' (gegenständliches Denken), a key concept for both. This theory developed from Heinroth's dealing with Goethe's concept of "anschauung" and was to gain major importance not only for his way of gaining knowledge in general but also for his psychiatric concept. Goethe's influence on Heinroth is particularly revealed in the latter's holistic views on mental illnesses. Heinroth's visit to Goethe on 15 September 1827 can be earmarked as a sign of their mutual esteem.

    The effect of docosahexaenoic acid (DHA) on heme oxygenase-1 (HO-1) expression in cancer cells has never been characterized. This study examines DHA-induced HO-1 expression in human cancer cell model systems. DHA enhanced HO-1 gene expression in a time- and concentration-dependent manner, with maximal induction at 21 h of treatment. This induction of HO-1 expression was confirmed in vivo using a xenograft nude mouse model fed a fish-oil-enriched diet. The increase in HO-1 gene transcription induced by DHA was significantly attenuated by the antioxidant N-acetyl cysteine, suggesting the involvement of oxidative stress. This was supported by direct measurement of lipid peroxide levels after DHA treatment. Using a human HO-1 gene promoter reporter construct, we identified two antioxidant response elements (AREs) that mediate the DHA-induced increase in HO-1 gene transcription. Knockdown of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) expression compromised the DHA-induced increase in HO-1 gene transcription, indicating the importance of the Nrf2 pathway in this event. However, the nuclear protein levels of Nrf2 remained unchanged upon DHA treatment. Further studies demonstrated that DHA reduces nuclear Bach1 protein expression by promoting its degradation and attenuates Bach1 binding to the AREs in the HO-1 gene promoter. In contrast, DHA enhanced Nrf2 binding to the AREs without affecting nuclear Nrf2 expression levels, indicating a new cellular mechanism that mediates DHA's induction of HO-1 gene transcription. To our knowledge, this is the first characterization of DHA-induced HO-1 expression in human malignant cells. Copyright © 2014 Elsevier Inc. All rights reserved.

    Alternagin-C (ALT-C) is a disintegrin-like protein purified from the venom of the snake, Rhinocerophis alternatus. Recent studies showed that ALT-C is able to induce vascular endothelial growth factor (VEGF) expression, endothelial cell proliferation and migration, angiogenesis and to increase myoblast viability. This peptide, therefore, can play a crucial role in tissue regeneration mechanisms. The aim of this study was to evaluate the effects of a single dose of alternagin-C (0.5 mg kg(-1), via intra-arterial) on in vitro cardiac function of the freshwater fish traíra, Hoplias malabaricus, after 7 days. ALT-C treatment increased the cardiac performance promoting: 1) significant increases in the contraction force and in the rates of contraction and relaxation with concomitant decreases in the values of time to the peak tension and time to half- and 90% relaxation; 2) improvement in the cardiac pumping capacity and maximal electrical stimulation frequency, shifting the optimum frequency curve upward and to the right; 3) increases in myocardial VEGF levels and expression of key Ca(2+)-cycling proteins such as SERCA (sarcoplasmic reticulum Ca(2+)-ATPase), PLB (phospholamban), and NCX (Na(+)/Ca(2+) exchanger); 4) abolishment of the typical negative force-frequency relationship of fish myocardium. In conclusion, this study indicates that ALT-C improves cardiac function, by increasing Ca(2+) handling efficiency leading to a positive inotropism and chronotropism. The results suggest that ALT-C may lead to better cardiac output regulation indicating its potential application in therapies for cardiac contractile dysfunction. Copyright © 2015 Elsevier Ltd.

    Effective antiviral therapy plays a key role in slowing the progression of chronic hepatitis B (CHB). Identification of serum indices, including hepatitis B e antigen (HBeAg) expression and seroconversion, will facilitate evaluation of the efficacy of antiviral therapy in HBeAg-positive CHB patients. The biochemical, serological, virological parameters, and the frequency of circulating CD4CD25 regulatory T cell (Treg) in 32 patients were measured at baseline and every 12 weeks during 96 weeks of tenofovir disoproxil fumarate (TDF) treatment. The relationship between the hepatitis B virus (HBV) deoxyribonucleic acid (DNA) and Treg and alanine aminotransferase (ALT) levels was analyzed, respectively. The molecular profiles of T-cell receptor beta variable chain (TRBV) were determined using gene melting spectral pattern. For the seroconverted 12 patients, ALT declined to normal levels by week 24 and remained at this level in subsequent treatment; moreover, the predictive cutoff value of ALT for HBeAg seroconversion (SC) was 41.5 U/L at week 24. The positive correlation between HBV DNA and Treg and ALT was significant in SC patients, but not in non-SC patients. Six TRBV families (BV3, BV11, BV12, BV14, BV20, and BV24) were predominantly expressed in SC patients at baseline. The decline of ALT could be used to predict HBeAg seroconversion for CHB patients during TDF treatment. In addition, the profile of Tregs and TRBVs may be associated with HBeAg seroconversion and could also be a potential indicator for predicting HBeAg SC and treatment outcome for CHB patients.

    Six poly(phenylene- alt -dithienobenzothiadiazole)-based polymers have been synthesized for application in polymer-fullerene solar cells. Hydrogen, fluorine, or nitrile substitution on benzo-thiadiazole and alkoxy or ester substitution on the phenylene moiety are investigated to reduce the energy loss per converted photon. Power conversion efficiencies (PCEs) up to 6.6% have been obtained. The best performance is found for the polymer-fullerene combination with distinct phase separation and crystalline domains. This improves the maximum external quantum efficiency for charge formation and collection to 66%. The resulting higher photocurrent compensates for the relatively large energy loss per photon ( E loss = 0.97 eV) in achieving a high PCE. By contrast, the poly-mer that provides a reduced energy loss ( E loss = 0.49 eV) gives a lower photocurrent and a reduced PCE of 1.8% because the external quantum efficiency of 17% is limited by a suboptimal morphology and a reduced driving force for charge transfer.

    Full Text Available In this work, we report separator membranes from crosslinking of two polymers, such as poly vinyl alcohol (PVA with an ionic polymer poly(methyl vinyl ether-alt-maleic anhydride (PMVE-MA. Such interpolymer-networked systems were extensively used for biomedical and desalination applications but they were not examined for their potential use as membranes or separators for batteries. Therefore, the chemical interactions between these two polymers and the influence of such crosslinking on physicochemical properties of the membrane are systematically investigated through rheology and by critical gel point study. The hydrogen bonding and the chemical interaction between PMVE-MA and PVA resulted in highly cross-linked membranes. Effect of the molecular weight of PVA on the membrane properties was also examined. The developed membranes were extensively characterized by studying their physicochemical properties (water uptake, swelling ratio, and conductivity, thermal and electrochemical properties using differential scanning calorimetry (DSC, dynamic mechanical analysis (DMA, thermo-gravimetric analysis (TGA and electrochemical impedance spectroscopy (EIS. The DSC study shows the presence of a single Tg in the membranes indicating compatibility of the two polymers in flexible and transparent films. The membranes show good stability and ion conductivity suitable for separator applications.

Uno de los municipios situados en el límite de la plana altoampurdanesa que mejor ejemplifican este proceso de abandono y casi desaparición del olivar es Navata. Este artículo analiza los cambios experimentados en el olivar de este municipio en el periodo 1957-2004 a través tanto de la elaboración de una cartografía de usos y cubiertas del suelo a escala de detalle como del análisis de fuentes estadísticas y orales, ejercicio que pone de relieve la pérdida del 90% del olivar existente a mediados del siglo pasado. La helada de febrero de 1956 fue uno de los principales causantes, pero no el único. Sin embargo, tanto la importancia del olivar como elemento identitario y de conservación de la biodiversidad como el carácter diferenciador del aceite que se obtiene a partir de variedades propias de la zona (especialmente la argudell, justifican la necesidad de impulsar políticas que ayuden a su recuperación.

    Thermographic measurements using an IR scanner have been performed at the pump limiter ALT-II of TEXTOR-94 during RI mode discharges and during disruptions. The measurements on the RI mode discharges were done to complete the TEXTOR database which had shown a structured decay pattern of the deposited power. It was found that the underlying radial heat flux can be described by two exponential decay functions. This structure, which generates an unexpected heat component close to the tangent line, has been observed in all discharge conditions including the RI mode. During disruptions, the heat is released in short pulses with a typical duration of 0.01-0.1 ms. The radial decay length of these pulses has a similar shape to the heat flux during normal discharges: it consists again of a strong component close to the tangent line with a radial decay length of 2-5 mm and probably one with a decay length of the order of 1 cm. The heat is released at the time when the edge electron temperature of the plasma drops, when intense hydrogen and carbon fluxes occur near the walls, and when electrical currents in the limiter blades are excited. In a tentative interpretation, the temporal and spatial structure of the heat pulse is attributed to the presence and growth of a laminar zone at the plasma edge, which is connected with the ergodization of the plasma edge during a disruption.

    Radiation-induced grafting of styrene onto ETFE films in different solvent was investigated after simultaneous irradiation (in post-irradiation condition) using a 60Co source. Grafting of styrene followed by sulfonation onto poly(ethylene-alt-tetrafluoroethylene) (ETFE) are currently studied for synthesis of ion exchange membranes. The ETFE films were immersed in styrene/toluene, styrene/methanol and styrene/isopropyl alcohol and irradiated at 20 and 100 kGy doses at room temperature. The post-irradiation time was established at 14 day and the grafting degree was evaluated. The grafted films were sulfonated using chlorosulfonic acid and 1,2-dichloroethane 20:80 (v/v) at room temperature for 5 h. The degree of grafting (DOG) was determined gravimetrically and physical or chemical changes were evaluated by differential scanning calorimeter analysis (DSC), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The ion exchange capacity (IEC) values showed the best performance of sulfonation for ETFE membranes grafted in toluene solvent. Surface images of the grafted films by SEM technique have presented a strong effect of the solvents on the films morphology.

    MoHrip1, a protein isolated from Magnaporthe oryzae, belongs to the Alt A 1 (AA1) family. mohrip1 mRNA levels showed inducible expression throughout the infection process in rice. To determine the location of MoHrip1 in M. oryzae, a mohrip1-gfp mutant was generated. Fluorescence microscopy observations and western blotting analysis showed that MoHrip1 was both present in the secretome and abundant in the fungal cell wall. To obtain MoHrip1 protein, we carried out high-yield expression of MoHrip1 in Pichia pastoris. Treatment of tobacco plants with MoHrip1 induced the formation of necrosis, accumulation of reactive oxygen species and expression of several defense-related genes, as well as conferred disease resistance. By fusion to green fluorescent protein, we showed that MoHrip1 was able to bind to the tobacco and rice plant plasma membrane, causing rapid morphological changes at the cellular level, such as cell shrinkage and chloroplast disorganization. These findings indicate that MoHrip1 is a microbe-associated molecular pattern that is perceived by the plant immune system. This is the first study on an AA1 family protein that can bind to the plant plasma membrane. Copyright © 2017 Elsevier Inc. All rights reserved.

    This paper provides significant ethnobotanical information on pharmaceutical plant uses from a tourist and industrialised region, where some degree of acculturation exists, so that there is urgency in recording such data. To collect, analyze and evaluate the ethnobotanical knowledge about medicinal plants in a north-eastern Iberian region (Alt Empordà, 1358 km(2), 129,160 inhabitants). We performed 101 semi-structured interviews with 178 informants (mean age 69; 71% women, 29% men), identified the plant taxa reported and analyzed the results, comparing them with those from other territories. The informants reported data on 518 species. Of these, 335, belonging to 80 botanical families, were claimed as medicinal. This work is focused on human medicinal plant uses, which represent 98% of the pharmaceutical uses (3581 out of 3643 use reports). Around 800 medicinal uses, concerning 200 species, have not, or have very rarely been cited as medicinal; of these, 32 uses of 30 species have been reported by three or more independent informants. The folk knowledge about medicinal plant use is still alive in the studied region, and a number of scarcely reported plant uses has been detected, some of them with promising phytotherapeutical applications.

    Full Text Available A paper-based, multiplexed, microfluidic assay has been developed to visually measure alanine aminotransferase (ALT in a fingerstick sample, generating rapid, semi-quantitative results. Prior studies indicated a need for improved accuracy; the device was subsequently optimized using an FDA-approved automated platform (Abaxis Piccolo Xpress as a comparator. Here, we evaluated the performance of the optimized paper test for measurement of ALT in fingerstick blood and serum, as compared to Abaxis and Roche/Hitachi platforms. To evaluate feasibility of remote results interpretation, we also compared reading cell phone camera images of completed tests to reading the device in real time.96 ambulatory patients with varied baseline ALT concentration underwent fingerstick testing using the paper device; cell phone images of completed devices were taken and texted to a blinded off-site reader. Venipuncture serum was obtained from 93/96 participants for routine clinical testing (Roche/Hitachi; subsequently, 88/93 serum samples were captured and applied to paper and Abaxis platforms. Paper test and reference standard results were compared by Bland-Altman analysis.For serum, there was excellent agreement between paper test and Abaxis results, with negligible bias (+4.5 U/L. Abaxis results were systematically 8.6% lower than Roche/Hitachi results. ALT values in fingerstick samples tested on paper were systematically lower than values in paired serum tested on paper (bias -23.6 U/L or Abaxis (bias -18.4 U/L; a correction factor was developed for the paper device to match fingerstick blood to serum. Visual reads of cell phone images closely matched reads made in real time (bias +5.5 U/L.The paper ALT test is highly accurate for serum testing, matching the reference method against which it was optimized better than the reference methods matched each other.

    This study presents the results of the response of Sparus aurata to three different musical stimuli, derived from the transmission (4 h per day, 5 days per week) of particular music pieces by Mozart, Romanza and Bach (140 dB(rms) re 1 μPa), compared to the same transmission level of white noise, while the underwater ambient noise in all the experimental tanks was 121 dB(rms) re 1 μPa. Using recirculating sea water facilities, 10 groups, 2 for each treatment, of 20 specimens of 11.2 ± 0.02 g (S.E.), were reared for 94 days, under 150 ± 10 l× 12L-12D, and were fed an artificial diet three times per day. Fish body weight showed significant differences after 55 days, while its maximum level was observed after the 69th day until the end of the experiment, the highest value demonstrated in Mozart (M) groups, followed by those of Romanza (R), Bach (B), control (C) and white noise (WN). SGR (M = B), %WG (M = B) and FCR (all groups fed same % b.w.) were also improved for M group. Brain neurotransmitters results exhibited significant differences in DA-dopamine, (M > B), 5HIAA (C > B), 5HIAA:5HT (WN > R), DOPAC (M > B), DOPAC:DA and (DOPAC + HVA):DA, (C > M), while no significant differences were observed in 5HT, NA, HVA and HVA:DA. No differences were observed in biometric measurements, protease activity, % fatty acids of fillet, visceral fat and liver, while differences were observed regarding carbohydrase activity and the amount (mg/g w.w.) of some fatty acids in liver, fillet and visceral fat. In conclusion, present results confirm those reported for S. aurata, concerning the observed relaxing influence--due to its brain neurotransmitters action--of the transmission of Mozart music (compared to R and B), which resulted in the achievement of maximum growth rate, body weight and improved FCR. This conclusion definitely supports the musical "understanding" and sensitivity of S. aurata to music stimuli as well as suggesting a specific effect of white noise.

Les énonciateurs-voyageurs, placés dans un contexte linguistique et culturel asymétrique, tentent de saisir et de transcrire leurs observations sur le terrain étranger en fonction de leur intellect, de leur cognition et de leur expérience. Une série d’éléments marqués par l’altérité viennent modifier la représentation que l’auteur-voyageur donne du référent et de l’univers référentiel auquel il est confronté.

    Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and γ-glutamyl transferase (GGT) measurements are important for the assessment of liver damage. The aim of this study was to define the reference intervals (RIs) for these enzymes in adults, paying attention to standardization of the methods used and careful selection of the reference population. AST, ALT and GGT were measured with commercial analytical systems standardized to the IFCC-recommended reference measurement systems. Three centers (two in Italy and one in China) measured their own freshly collected samples; one of these centers also measured frozen samples from the Nordic Countries RI Project and from a Turkish center. RIs were generated using non-parametric techniques from the results of 765 individuals (411 females and 354 males, 18-85 years old) selected on the basis of the results of other laboratory tests and a specific questionnaire. AST results from the four regions (Milan, Beijing, Bursa and Nordic Countries) were statistically different, but these differences were too small to be clinically relevant. Likewise, differences between the upper reference limits for genders was only 1.7 U/L (0.03 μkat/L), allowing a single RI of 11-34 U/L (0.18-0.57 μkat/L) to be defined. Interregional differences were not statistically significant for ALT, but partitioning was required due to significant gender differences. RIs for ALT were 8-41 U/L (0.13-0.68 μkat/L) for females and 9-59 U/L (0.15-0.99 μkat/L) for males, respectively. The upper reference limits for GGT from the Nordic Country population were higher than those from the other three regions and results from this group were excluded from final calculations. The GGT RIs were 6-40 U/L (0.11-0.66 μkat/L) for females and 12-68 U/L (0.20- 1.13 μkat/L) for males, respectively. For AST and ALT, the implementation of common RIs appears to be possible, because no differences between regions were observed. However, a common RI for GGT that is

    Alternagin-C (ALT-C) is a disintegrin-like protein isolated from Rhinocerophis alternatus snake venom, which induces endothelial cell proliferation and angiogenesis. The aim of this study was to evaluate the systemic effects of a single dose of alternagin-C (0.5 mg·kg -1 , via intra-arterial) on oxidative stress biomarkers, histological alterations, vascular endothelial growth factor (VEGF) production, and the degree of vascularization in the liver of the freshwater fish traíra, Hoplias malabaricus , seven days after the initiation of therapy. ALT-C treatment increased VEGF levels and hepatic angiogenesis. ALT-C also enhanced hepatic antioxidant enzymes activities such as superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase, decreasing the basal oxidative damage to lipids and proteins in the fish liver. These results indicate that ALT-C improved hepatic tissue and may play a crucial role in tissue regeneration mechanisms.

    Gels are a special class of materials which are composed of 3D networks of crosslinked polymer chains that encapsulate liquid/air in the matrix. They can be classified into organogels or hydrogels (organic solvent for organogel and water for hydrogel). For hydrogels that contain metallic elements in the form of ions, the term of metallo-supramolecular polymer hydrogel (MSPHG) is often used. The aim of this project is to develop a kind of new MSPHG and investigate its properties and possible applications. The commercial polymeric anhydride poly(methyl vinyl ether-alt-maleic anhydride) (PVM/MA) is converted by reaction with NaOH to give poly(methyl vinyl ether-alt-monosodium maleate) (PVM/Na-MA). By addition of AgNO3-solution, the formation of the silver(I) supramolecular polymer hydrogel poly[methyl vinyl ether-alt-mono-sodium maleate]∙AgNO3 is obtained. Freeze-dried samples of the hydrogel show a mesoporous network of polycarboxylate ligands that are crosslinked by silver(I) cations. The supercritical CO2 dried silver(I) hydrogel was characterized by FT-IR, SEM-EDAX, TEM, TGA and Physical adsorption (BET) measurements. The intact silver(I) hydrogel was characterized by cryo-SEM. In the intact hydrogel, ion-exchange studies are reported and it is shown that Ag+ ions can be exchanged by copper(II) cations without disintegration of the hydrogel. The silver(I) hydrogel shows effective antibacterial activity and potential application as burn wound dressing.

    Full Text Available Se compara el modelo estándar reducido de tres poblaciones (hepatocitos sanos y enfermos, y carga viral para el estudio de la dinámica del virus de la hepatitis C (VHC, con el modelo de la dinámica viral con alanina aminotransferasa (ALT. En términos del parámetro umbral que es el mismo para ambos modelos, se determina la existencia y estabilidad del estado de equilibrio endémico, así como la estabilidad global del estado de equilibrio del individuo sano. Por otro lado, se presenta un estudio experimental que muestra que es posible monitorear el daño hepático sin biopsias, mediante la estimación numérica de los parámetros de los modelos, considerando solamente mediciones de la carga viral, de los niveles de ALT y una valoración razonable del daño hepático pretratamiento.aThe standard model of three populations (healthy and unhealthy hepatocytes, and viral load for the study of the dynamics of hepatitis C virus (HCV, is compared with viral dynamic model with alanine aminotransferase (ALT. In terms of the threshold parameter that it’s the same for both models, the existence and local asymptotic stability of the endemically infected equilibrium steady state, and the global stability of the healthy individual equilibrium steady state are established. Furthermore, an experimental study is presented showing that it’s possible to carry out the monitoring of hepatic damage biopsies free by numerical parameter estimation, considering only viral load and ALT levels measurements and a reasonable assessment of pretreatment hepatic damage.

    Full Text Available Electrochemical preparation of a composite consisting of poly[2,2′-bis(3,4-ethylenedioxythiophene-alt-fluorene] and hydroxypropyl cellulose (PEFE/HPC was carried out. We conducted electrochemical polymerization of poly[2,2′-bis(3,4-ethylenedioxythiophene-alt-fluorene] (EFE as a monomer in a lyotropic liquid crystal of HPC. We used an organic solvent instead of water for lyotropic liquid crystal medium to expand the possibility of the range of monomers, although water is usually employed as a solvent for HPC for showing liquid crystallinity. Here, we employed N,N-dimethylformamide (DMF as a solvent for HPC. Electrochemical polymerization in the polymer liquid crystal was carried out to obtain a polymer film with liquid crystal order. The polymer film thus prepared exhibited optical activity. Fourier transfer infrared (FT-IR absorption spectroscopy reveals that the film is a composite consisting of HPC and polymer. The composite PEFE/HPC thus prepared in HPC/DMF system showed electrochromism.

  9. Influence of the composition of hydroxypropyl cellulose/maleic acid-alt-styrene copolymer blends on their properties as matrix for drug release

    2009-05-01

    Full Text Available Poly(carboxylic acid-polysaccharide compositions have been found suitable for obtaining drug formulations with controlled release, most formulations being therapeutically efficacious, stable, and non-irritant. The influence of the characteristics of the aqueous solutions from which the polymer matrix is prepared (i.e. the total concentration of polymer in solutions and the mixing ratio between the partners, hydroxypropyl cellulose, HPC and maleic acid-alternating-styrene copolymer, MAc-alt-S on the kinetics of some drugs release in acidic environment (pH = 2 has been followed by ‘in vitro’ dissolution tests. It has been established that the kinetics of procaine hydrochloride release from HPC/MAc-alt-S matrix depends on its composition; the diffusion exponent, n is close to 0.5 for matrices where one of the components is in large excess and n~0.02 for middle composition range. The lower value of diffusion exponent for middle composition range could be caused by the so called ‘burst effect’, therefore the kinetic evaluation is difficult.

    Purpose ALT-801 is a bifunctional fusion protein comprising interleukin-2 (IL-2) linked to a soluble, single-chain T cell receptor domain that recognizes a peptide epitope (aa264-272) of the human p53 antigen displayed on cancer cells in the context of HLA-A*0201 (p53+/HLA-A*0201). We evaluated the safety, pharmacokinetics and pharmacodynamics of ALT-801 in p53+/HLA-A*0201 patients with metastatic malignancies. Experimental Design p53+/HLA-A*0201 patients were treated with ALT-801 on a schedule of 4 daily 15-minute intravenous infusions, then 10 days rest and 4 more daily infusions. Cohorts of patients were treated at 0.015, 0.040, and 0.080 mg/kg/dose. Results Four, sixteen, and six patients were treated at the 0.015, 0.04 and 0.08 mg/kg cohorts, respectively. Two dose limiting toxicities (a grade 4 transient thrombocytopenia and a myocardial infarction) in the 0.08 mg/kg cohort established the maximum tolerated dose (MTD) at 0.04 mg/kg. Patients treated at the MTD experienced toxicities similar to those associated with high-dose IL-2 but of lesser severity. The serum half-life of ALT-801 was 4 hours and ALT-801 serum recovery was as expected based on the dose administered. ALT-801 treatment induced an increase of serum interferon-γ but not tumor necrosis factor-α. Response assessment showed 10 subjects with stable disease at at least 11 weeks, and in one who had melanoma metastasis, there is an ongoing complete absence of identifiable disease after resection of radiographically identified lesions. Conclusion This first-in-man study defines an ALT-801 regimen that can be administered safely and is associated with immunological changes of potential antitumor relevance. PMID:21994418

    Full Text Available Class III malocclusion is very common malocclusion and can be due to maxillary retrusion, mandibular prognathism, or combination. Ellis and McNamara found a combination of maxillary retrusion and mandibular protrusion to be the most common skeletal relationship (30%. The treatment should be carried out as early as possible for permitting normal growth of the skeletal bases. Reverse pull head gear combined with maxillary expansion can effectively correct skeletal Class III malocclusion due to maxillary deficiency in growing patient. An eight-year-old female patient with chief complaint of prognathic mandible and anterior crossbite was successfully treated in duration of 5 months with facemask and expansion therapy based on Alternate Rapid Maxillary Expansion and Constriction (Alt-RAMEC protocol.

    The levels of liver function tests (LFTs) are often used to assess liver injury and non-liver disease-related mortality. In our study, the relationship between pretreatment serum LFTs and overall survival (OS) was evaluated in esophageal squamous cell carcinoma (ESCC) patients. Our purpose was to investigate the prognostic value of the preoperative alanine aminotransferase/aspartate aminotransferase (ALT/AST) ratio and gamma glutamyltransferase (GGT) in ESCC patients. A retrospective study was performed in 447 patients with ESCC, and follow-up period was at least 60 months until death. The prognostic significance of serum LFTs were determined by univariate and multivariate Cox hazard models. LFTs including ALT, AST, LSR, GGT, TBA and LDH were analyzed. Serum LSR (HR: 0.592, 95% CI = 0.457-0.768, p < 0.001 and GGT (HR: 1.507, 95% CI = 1.163-1.953, p = 0.002) levels were indicated as significant predictors of OS. The 5-year OS among patients with higher LSR levels was longer compared with those patients with decreased LSR levels, not only in the whole cohort but also in the subgroups stratified by pathological stage (T1-T2 subgroup, T3-T4 subgroup, N0 subgroup and M0 subgroup). We also found that patients with a higher GGT might predict worse OS than patients with a normal GGT, not only in the whole cohort but also in the subgroups stratified by pathological stage (T3-T4 subgroup and N1-N2 subgroup). Both increased levels of LSR and decreased levels of GGT might predict shorter overall survival in ESCC patients. Our findings suggest that serum LSR and GGT levels could be used as a key predictor of survival in patients with ESCC.

    Objective: To investigate the value of non-invasive liver fibrosis models, FIB-4, S index, aspartate aminotransferase to platelet ratio index(APRI), globulin-platelet(GP)model, aspartate aminotransferase/platelet/gamma-glutamyl transpeptidase/alpha-fetoprotein(APGA), and platelet/age/phosphatase/alpha-fetoprotein/aspartate aminotransferase(PAPAS), in the diagnosis of marked liver fibrosis in chronic hepatitis B(CHB)patients with ALT liver biopsy was performed to obtain pathological results, and routine serological tests were performed, including routine blood test, serum biochemical parameters, hepatitis B virus(HBV)markers, and HBV DNA. According to liver pathology, the patients were divided into non-marked liver fibrosis group(S liver fibrosis group(S≥2)with 65 patients. The non-invasive models for predicting liver fibrosis was established with reference to original articles. SPSS 19.0 software was used for statistical analysis, and the receiver operating characteristic(ROC)curve was used to compare the value of different non-invasive models in predicting marked liver fibrosis in this population. Results: All the non-invasive models had a certain diagnostic value for liver fibrosis degree in these patients, and the areas under the ROC curve for APRI, FIB-4, APGA, S index, PAPAS, and GP model were 0.718, 0.691, 0.758, 0.729, 0.673, and 0.691, respectively. APGA had the largest area under the ROC curve(0.758, 95% CI 0.673-0.844), and gamma-glutamyl transpeptidase was significantly positively correlated with liver fibrosis degree. Conclusion: The non-invasive models of liver fibrosis can identify marked liver fibrosis in CHB patients with ALT liver biopsy to the certain degree.

    This article presents a short biography of Pauli in which we find the most important facts of his scientific career and some stunning sides of his personality. Pauli was born in 1900 in Vienna in an intellectual family. He was very soon interested in physics. At the age of 21 he published a relevant article on relativity, and the same year he presented a doctorate thesis on the quantum description of the H{sub 2}{sup +} molecular ion. As soon as 1925, Pauli discovered the exclusion principle (for which he will receive the Nobel prize in 1945), and was the first to calculate the energy levels of the hydrogen atom by using the Heisenberg formalism. In 1930, he suggested the existence of an unknown particle (the neutrino) to explain the continuous spectrum of the beta decay. In 1934, he found a link between the spin and the quantum statistics that is now called the spin-statistic theorem. Pauli died in december 1958 from a pancreas tumor. (A.C.)

    Full Text Available AbstractIn this study, the relationship between time-variables of the physical education lesson and fundamental movement skill acquisition and learning was examined. One hundred and ten first grade students and their six physical educators participated. Students were pre-, post-, and re-tested both qualitatively and quantitatively on overhand throwing and catching. The Test of Gross Motor Development (Ulrich, 1985 was used for the assessment of qualitative skill performance and the Michigan Educational Assessment Program (MEAP, 1984 for the assessment of quantitative skill performance. Between pre- and post-tests students received an eight lessons unit instruction with emphasis on overhand throwing and catching. A total number of thirty-six students (6 students X 6 schools were selected, andtheir videotaped motor behavior in the lessons was analyzed with the Academic Learning Time ¿ Physical Education (ALT-PE,Parker, 1989. Regression analysis was applied to calculate students´ residual scores of achievement and to enable further data analysis. Correlation analysis between students´ achievement and ALT-PE categories indicated significant relationships between skill acquisition, learning and ALT-PE categories. It can be concluded that time devoted to practice skills, unlike times pent on activities irrelevant to the instructional task oron games, contributes to skill learning.ResumenEn este trabajo se estudia la relación entre variables temporales de las clases de Educación Física y la adquisición y aprendizaje de habilidades motrices fundamentales.

    Objective: To study the correlationship between the serum levels of PAB, CHE, TBA, ALT and the severity of the disease process in patients with chronic virus B hepatitis. Methods: Serum levels of PAB, CHE, ALT (with biochemical methods) and TBA (with RIA) were examined in 93 patients with biopsy proven virus B hepatitis and 46 controls. Results: The 93 patients were of two groups: a less advanced group (n=51) and a more advanced group (n=42). Serum TBA, ALT levels were significnatly higher and serum PAB, CHE levels were significantly lower in the more advanced group than those in the less advanced group (P 0 to s 4 . Changes of levels of ALT were of no regular pattern, but serum levels of TBA regularly increased and levels of PAB, CHE regularly decreased as the fibrosis grading proceeded from s 0 to s 4 and the differences between the levels in s 4 and any other grading were significant (P<0.01). Conclusion: Combined determination of these serum markers might reflect the degree of inflammatory process and hepatic fibrosis in patients with virus B hepatitis, leading to earlier detection of cirrhosis.

Chemical and physical structures, surface morphologies, thermal behaviors, electrical conductivity and thermal resistance parameters of nanofiber structures were investigated. Poly(VP-alt-MA was used both as a crosslinker and a donor of the hydrophilic groups such as ‒COOH and ‒NH–C=O amide from pyrrolidone ring. Reactive poly(VP-alt-MA, in situ generated Ag nanoparticles (AgNPs and original partner polymer had an significant effect on the morphology and diameter distribution of nanofibers. High and excellent conductive behaviors were observed for the homopolymer and copolymer of VP based fiber structures, respectively. Upon successive chemical cross-linking of the nanofiber structures by reactive partner copolymer, the conductivity of nanofiber films as electro-active platforms dramatically increased to 3.90·10–2 S·cm–1 at room temperature. Comparative analysis results also indicated that electrical properties strongly depended on the loaded reactive organoclay and in situ generated AgNPs.

    The morphology of polystyrene-grafted poly(ethylene-alt-tetrafluoroethylene) (ETFE) films prepared using a simultaneous radiation grafting method was investigated using DMA, DSC, XRD, and SAXS instruments. The DMA study indicates that the ETFE amorphous phase and PS amorphous phase are mixed well in the PS-grafted ETFE films while the ETFE crystalline phase and the PS amorphous phase are separated, suggesting that the PS chains are grafted mainly on the ETFE amorphous regions. The DSC and XRD data showed that the natural crystalline structures of ETFE in the grafted ETFE films are not affected by the degree of grafting. The SAXS profiles displayed that the inter-crystalline distance of the ETFE films increases with an increasing degree of grafting, which further implies that the PS graft chains formed by the simultaneous irradiation has a significant impact on the amorphous morphology of the resulting grafted ETFE film. Thus, these results indicate that the styrene monomers are mainly grafted on the ETFE amorphous regions during the simultaneous radiation grafting process. - Highlights: • PS-grafted ETFE films were prepared by a simultaneous radiation grafting method was investigated. • The natural crystalline structures of grafted ETFE films are not affect by the degree of grafting. • The inter-crystalline distance of the ETFE films increase with increasing degree of grafting. • The styrene monomers are mainly grafted on the ETFE amorphous regions during a simultaneous radiation grafting using gamma-ray

    Grafting of styrene followed by sulfonation onto poly(ethylene-alt-tetrafluoroethylene) (ETFE) was studied for synthesis of ion exchange membranes. Radiation-induced grafting of styrene onto ETFE films was investigated after simultaneous irradiation (in post-irradiation condition) using a {sup 60}Co source. The ETFE films were irradiated at 20 kGy dose at room temperature and chemical changes were monitored after contact with styrene for grafting. The post-irradiation time was established at 14 days when the films were remained in styrene/toluene 1:1 v/v. After this period the grafting degree was evaluated in the samples. The grafted films were sulfonated using chlorosulfonic acid and 1, 2-dichloroethane 20:80 (v/v) at room temperature for 5 h. The membranes were analyzed by infrared spectroscopy (FTIR), differential scanning calorimeter (DSC), thermogravimetric measurements (TG) and degree of grafting (DOG). The ion exchange capacity (IEC) of membranes was determined by acid-base titration and the values for ETFE membranes were achieved higher than Nafion films. Preliminary single cell performance was made using pure H{sub 2} and O{sub 2} as reactants at a cell temperature of 80 deg. C and atmospheric gas pressure. The fuel cell performance of ETFE films was satisfactory when compared to state-of-art Nafion membranes.

    Grafting of styrene followed by sulfonation onto poly(ethylene-alt-tetrafluoroethylene) (ETFE) was studied for synthesis of ion exchange membranes. Radiation-induced grafting of styrene onto ETFE films was investigated after simultaneous irradiation (in post-irradiation condition) using a 60Co source. The ETFE films were irradiated at 20 kGy dose at room temperature and chemical changes were monitored after contact with styrene for grafting. The post-irradiation time was established at 14 days when the films were remained in styrene/toluene 1:1 v/v. After this period the grafting degree was evaluated in the samples. The grafted films were sulfonated using chlorosulfonic acid and 1, 2-dichloroethane 20:80 (v/v) at room temperature for 5 h. The membranes were analyzed by infrared spectroscopy (FTIR), differential scanning calorimeter (DSC), thermogravimetric measurements (TG) and degree of grafting (DOG). The ion exchange capacity (IEC) of membranes was determined by acid-base titration and the values for ETFE membranes were achieved higher than Nafion ® films. Preliminary single cell performance was made using pure H 2 and O 2 as reactants at a cell temperature of 80 °C and atmospheric gas pressure. The fuel cell performance of ETFE films was satisfactory when compared to state-of-art Nafion ® membranes.

  8. Rhodium-Coordinated Poly(arylene-ethynylene)-alt-Poly(arylene-vinylene) Copolymer Acting as Photocatalyst for Visible-Light-Powered NAD+/NADH Reduction

    Science.gov (United States)

    2014-01-01

    A 2,2′-bipyridyl-containing poly(arylene-ethynylene)-alt-poly(arylene-vinylene) polymer, acting as a light-harvesting ligand system, was synthesized and coupled to an organometallic rhodium complex designed for photocatalytic NAD+/NADH reduction. The material, which absorbs over a wide spectral range, was characterized by using various analytical techniques, confirming its chemical structure and properties. The dielectric function of the material was determined from spectroscopic ellipsometry measurements. Photocatalytic reduction of nucleotide redox cofactors under visible light irradiation (390–650 nm) was performed and is discussed in detail. The new metal-containing polymer can be used to cover large surface areas (e.g. glass beads) and, due to this immobilization step, can be easily separated from the reaction solution after photolysis. Because of its high stability, the polymer-based catalyst system can be repeatedly used under different reaction conditions for (photo)chemical reduction of NAD+. With this concept, enzymatic, photo-biocatalytic systems for solar energy conversion can be facilitated, and the precious metal catalyst can be recycled. PMID:25130570

    Full Text Available From the beginnings of what we now know as our modernity, man has been surprised with his own finitude. The 18th and 19th  century bourgeois needed to formulate complex ways of preserving the past and of linking with it. In the philosophes’ circle, time concept starts to double itself in the idea of origin, that, for them, had become opaque. We just need to think of the broad-range process of structuring museums and restructuring natural history collections in cities such as Paris and Berlin, around the turn to the 19th century, so that we can be convinced that the surprise with that origin that one cannot recognize anymore, that becomes object of popular and scientific interest, leads each and all of the decisions in this process. Museum is just one of the institutions in which man, through a complex series of idealizations of space, show himself the spectacle of a lost time and, thus, of a culture whose educational thrive can only be understood by associating to these institutions. Our task is to investigate – and the case study of the grounding of the Altes Museum in Berlin, between 1822 and 1830, will perform this concretely – which educational policy made the emergence of this new ideological model possible, and , on the opposite way, which conceptual elaborations confirmed or legitimated the new pragmatic topography of time in modernity within the institution that had as aim, precisely, articulate and administrate past and memory. Desde los albores de la modernidad tal como la entendemos hoy en día, el hombre se espanta por su finitud. El burgués de los siglos XVIII y XIX tuvo que crear mecanismos complejos para la preservación del pasado y su relación con él. En el círculo de philosophes, la noción del tiempo comienza a replicarse en la idea de origen, que para ellos se convirtió en opaca. Basta pensar en el amplio

    © The Royal Society of Chemistry 2016. In this study, a new triphenylamine-alt-fluorene conjugated copolymer, HPBPYFL6, with hexaphenylbenzene (HPB) and pyrene as asymmetrical pendant groups was synthesized via Suzuki coupling polymerization. The conjugated polymer had a weight-average molecular weight of 5.8 × 104 g mol-1 with a polydispersity index of 2.5 characterized by gel permeation chromatography (GPC). HPBPYFL6 showed good solubility in common organic solvents such as NMP, THF, toluene and dichloromethane at 25°C. In addition, HPBPYFL6 possessed a high glass transition temperature of 260°C and a 10% weight-loss temperature of 503°C in nitrogen. HPBPYFL6 bearing a pyrene moiety had a solvatochromic fluorescence shift from a green to an orange emission as the polarity of the solvent increased. Cyclic voltammetry of HPBPYFL6 films cast onto indium-tin oxide-coated glass (ITO-glass) exhibited two oxidation redox couples at an E1/2 value of 0.82 and 1.17 V versus Ag/Ag+ in an acetonitrile solution. The HPBPYFL6 film on graphene-coated PET had an E1/2 value of 0.24 and 1.12 V. Conjugated polymer films exhibited reversible electrochromic behaviour with a colour change from pale yellow to deep blue upon electrochemical oxidation and high absorbance in the near-infrared (NIR) region. The switching and bleaching times were 5.16 s and 3.12 s for 1231 nm and were 3.30 s and 3.74 s for 1030 nm of HPBPYFL6 on ITO-glass. The strong NIR electrochromic absorbance of HPBPYFL6 was attributed to intervalence charge transfer by the incorporation of the HPB moiety. This phenomenon was confirmed by chemical oxidation as the oxidant contents increased in the solution state. Furthermore, the electrochromic mechanism was interpreted by DFT calculation and the simulated NIR electrochromic spectra of model compound HPBPYFL are in good agreement with the experimental data.

    Polystyrene-block-poly(styrene-alt-maleic anhydride) was synthesized by nitroxide mediated radical polymerization and modified with 7-amino-4-methylquinolin-2(1H)-one (I) and methanol. The formed block polymer ligand contained a quinolinone fluorophore (Ω) and carboxyl (III) or sodium carboxylate (IV) binding sites. The ligand-to-metal resonance energy transfer (RET) and ligand binding properties of [III–Tb{sup 3+}] and [IV–Tb{sup 3+}] complexes were investigated by steady-state and time-resolved luminescence spectroscopy in tetrahydrofuran/methanol and/or tetrahydrofuran/deuterated methanol mixtures and compared with those of a low-molecular-weight model ligand, i.e. the sodium salt of N-(4-methyl-2-oxo-1,2-dihydroquinolin-7-yl)succinamic acid (II). The long-lived emission intensities of Tb{sup 3+} at 490, 545, 585, and 620 nm corresponding to the {sup 5}D{sub 4}→{sup 7}F{sub 6}, {sup 5}D{sub 4}→{sup 7}F{sub 5}, {sup 5}D{sub 4}→{sup 7}F{sub 4}, and {sup 5}D{sub 4}→{sup 7}F{sub 3} transitions, respectively, were strongly increased by the addition of ligands in the order [II-Tb{sup 3+}]⪡[III-Tb{sup 3+}]<[IV-Tb{sup 3+}]. The efficiency of energy transfer (E) was evaluated from the emission intensity of the donor (Ω) in the presence or absence of the acceptor (Tb{sup 3+}) depending on the acceptor concentration and ligand neutralization. It was concluded that the macromolecular ligand structural properties (polymer coil and supramolecular structures, e.g. micelles) were responsible for the increase in RET. The time-resolved luminescence measurements revealed that the binding affinity of the ligands II, III, and IV increased in the order II

No entanto, a freqüência de animais com vacuolização acentuada foi superior nos grupos que receberam dietas com FFM, apresentando também maiores teores de lipídios e colesterol total hepáticos e maior relação peso fígado/peso corporal. Estes resultados indicam que os antinutrientes presentes nas folhas de mandioca, como taninos, cianeto e saponinas, podem ser responsáveis pela redução da função hepática nos animais alimentados com FFM.Cassava leaves contain substances such as lignins and saponins that can present the hypolipidemic effect.

The specimen was an orphan male calf, with 137cm of length and estimated weight of 49kg. It presented bad nutritional conditions and a shark bite on the right shoulder area. Clinical management was performed for 56 days, anthelmintic Febendazole was utilized, and the bite was treated with iodined alcohol, Nitrofurazone solution and Kethanserin, simultaneously with Enrofloxacin 10%, Potenay®, Vitamin B Complex and Benerva®. On the 16th the animal presented a right unilateral conjuntivitis, treated with Cloranphenicol oftalmic pomade until the end of its stay in the captive. During this period a total of six blood samples were collected, three for total blood counts and the others for the biochemistry determination of ALT, AST and creatinine. According to the haematological analysis the seal developed an anaemia which was classified as microcytic and normochromic. Lymphopenia, eosinopenia and monocytopenia were also observed, possibly due to its handling and stress conditions. The clinical chemistry presented low values for AST and creatinine, although this did not represent the existence of any pathologic context or disease with clinical significance.

    Full Text Available This paper aims to highlight some interesting convergences between the theory of the meaning-construction of the literary text proposed by Iser in The Act of Reading and Pierre Hadot’s work on the hermeneutics of the text in ancient philosophy. As we know, Hadot interprets the specificities of the ancient philosophical text as functional to guide the mind of the reader in a path that does not only have a cognitive purpose, but rather a spiritual one. The concept of «spiritual excercise», central to Hadot’s work, presents similarities ­– that are potentially very productive – to the model of the use of the literary text in Iser. Moreover, it is apt to show the extraordinary theoretical importance of a series of details, which are seemingly quite technical. In particular, a dialogue between the two approaches of Iser and Hadot allows posing in a new way a question that literary theory typically marginalizes: that of the pragmatics of the literary text.

    W. A. Mozart died due to the consequences of chronic epidural hematoma after sustaining a dull injury to his head, probably at an early age. Exacerbation of the process was repeated over a period of many years and manifested itself as pyrexial disease, meningeal irritation with intense headaches. After the attack subsided, the illness manifested itself again. After the last attack of the likely infected nidus, Mozart died on December 5, 1791. Historic data about the composer's behavior indicate development of a temporal syndrome or temporal epilepsy with typical clinical manifestations.

    This work investigated the effect on 5 wt% addition of TiO{sub 2} nanoparticles (NPs) on the optical absorption characteristics of Poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-alt-(benzo[2,1,3] thiadiazol-4,8-diyl)] (F8BT). Both materials were mixed using solution blending method and then spin coated onto ITO-coated glass substrate at 1000 rpm for 30s. The optical properties of the nanocomposite were determined using UV-Vis spectroscopy. Compares to pristine film, the absorption peak of the nanocomposite film improved and shifted to longer wavelength indicating reduction in the direct and indirect band gaps. Better optophysical properties of F8BT/TiO{sub 2} nanocomposites is believed due to compatible band structures and efficient charge trapping effect displayed by the NPs.

    Full Text Available The potentially long and interesting archaeological sequence revealed by systematic survey at the site of Alt Del Punxó (Muro de l’Alcoi, Alacant was the basis for initiating a study of the locality’s subsurface structures using new methods of remote sensing. Geophysical survey (magnetometry and tomography and systematic augering revealed buried structures, including monumental earthworks, and guided subsequent excavations to collect more detailed data about the nature and age of these prehistoric features. The information recovered, including new radiocarbon dates, offers a new perspective on the organization of prehistoric populations in this region of south-central Valencia since the beginning of the Holocene and is especially important for understanding the Neolithic IIB from the 4th through the early 3rd Millennium BC.

    La amplia e interesante secuencia arqueológica sugerida por los materiales de superficie del yacimiento de Alt del Punxó (Muro de l’Alcoi, Alacant ha supuesto el punto de partida para la práctica de una serie de métodos de detección de las estructuras conservadas en el lugar. La prospección geofísica (magnetometría y tomografía, y los microsondeos (augers han dirigido la planificación de la excavación con el fin de obtener nuevos datos a propósito de la naturaleza y cronología del gran foso prehistórico, así como de las diversas estructuras localizadas. La información obtenida, junto a la serie radiocarbónica disponible, abre nuevas perspectivas para el estudio del poblamiento prehistórico al aire libre en las comarcas centro-meridionales valencianas desde los inicios del Holoceno, y de un modo particular en el IV e inicios del III milenio cal AC –Neolítico IIB.

FONTES DE DADOS: Revisão bibliográfica dos artigos (em português, inglês e espanhol obtidos dos bancos de dados eletrônicos Medline, Lilacs e SciELO, utilizando as palavras-chave: eventos com aparente risco de morte, evento com aparente risco de vida infantil, lactente, apneia, monitorização e cianose. SÍNTESE DOS DADOS: Os eventos com aparente risco de mortesão súbitos e caracterizados por uma combinação de apneia, alteração na coloração da pele e tônus muscular, com inúmeras causas subjacentes. Sua incidência verdadeira é desconhecida e a faixa etária mais acometida é de 11 a 12 semanas. Não há correlação entre o evento com aparente risco de morte e a síndrome da morte súbita do lactente, embora já tenham sido consideradas manifestações da mesma doença. Muitas vezes, o lactente tem aparência saudável ao ser avaliado pelo pediatra após apresentar eventos com aparente risco de morte, porém, isso não afasta a possibilidade de existir uma doença grave associada ao evento, que deve ser investigada e tratada. Quando não são encontradas as causas, o evento é idiopático, geralmente com boa evolução. CONCLUSÕES: É necessário investigar os lactentes levados ao pronto-socorro após apresentarem eventos com aparente risco de morte, devido ao risco de sequelas e mortalidade. Não há uma padronização das condutas a serem realizadas diante de um lactente com aparência saudável que tenha evento com aparente risco de morte, mas recomenda-se que o paciente seja internado e a causa do evento, investigada. A observação e o monitoramento em ambiente hospitalar devem ocorrer no mínimo 24 horas após o evento.OBJETIVO: Realizar una revisión crítica, reuniendo las informaciones disponibles respecto a los Eventos con Aparente Riesgo de Muerte (ALTE - Apparent life-threatening event

Conclusions miR-380-5p interferes with TA in DMPM cells by targeting TEP1. Notably, in the long-term setting, miR-380-5p-mediated impairment of TA did not result in telomere attrition. Instead, a phenotype reminiscent of ALT emerged in DMPM cells as possible compensatory pathway that safeguards DMPM cell growth, an event that may be regarded as a potential resistance mechanism to anticancer therapies based on telomerase inhibitors.

    Full Text Available Os materiais compósitos de matriz polimérica (PMCs reforçados por fibras são considerados excelentes materiais de engenharia. Em aplicações estruturais, quando uma elevada relação resistência peso é fundamental para o projeto, os PMCs vêm substituindo com sucesso diversos materiais convencionais. Materiais têxteis são utilizados, desde a 2ª Guerra Mundial, como blindagens balísticas. Materiais fabricados com fibra do polietileno de altíssimo peso molecular (UHMWPE são empregados na produção de blindagens, para proteção pessoal e em carros de combate. Todavia, em virtude de terem sido desenvolvidos e comercializados mais recentemente, não existem informações suficientes sobre o desempenho balístico desses materiais após a sua exposição aos agentes ambientais. No presente trabalho foi estudado o comportamento balístico de placas compósitas fabricadas com fibra de polietileno de altíssimo peso molecular (UHMWPE, após sua exposição à radiação gama. Os resultados dos testes balísticos foram relacionados com as alterações macromoleculares induzidas pela irradiação por meio de ensaios mecânicos (dureza, impacto e flexão e físico-químicos (espectroscopia no infravermelho, calorimetria diferencial de varredura e análise termogravimétrica. Foi verificado que a irradiação gama provoca modificações nas cadeias macromoleculares do polímero, que alteram as propriedades mecânicas do compósito de UHMWPE, reduzindo, nas doses de radiação mais elevadas, o seu desempenho balístico. Estes resultados são apresentados e discutidos.The fiber reinforced polymer matrix composites (PMCs are considered excellent engineering materials.

Ayet kuşağının üstündeki pervazlarla yükseltilen tavanın köşeleri çıtaların çakılması sonucu oluşturulmuş, üçgen yüzeylere bölünmüş ve böylece ortada sekizgen bir alan oluşturulmuştur. sekizgenin tam ortasında yer alan sekizgen formlu göbek, oyma tekniği ile işlenmiş, barok karakterli bitkisel motiflerle dekore edilmiştir. Tavanın dört köşesinde aşırı plastik bitkisel kabartmaların dekore ettiği üçgen panolar yer alır. Duvarlarda bitkisel motifli kalem-işi süslemeler, mahfil, minber, sütunce gibi ahşap unsurlarda da oyma tekniği ile işlenmiş bitkisel ve geometrik motifler cami içerisinde adeta boş yer kalmamacasına göz alıcı bir zenginlik sunmaktadır.1801 yılında yapılan, Cumhuriyetin ilk yıllarında da yöreye özgü tatlı-kireç sıvayla kapatılıp üstüne boya çekilen bu zengin dekorasyon, Türk ahşap sanatının ve kalem-işi süslemeciliğinin en zengin örneklerini sunmaktadır.

  14. The re-enchantment of nature - Wolfgang Pauli's philosophy of quantum physics

    International Nuclear Information System (INIS)

    Nair, Ranjit

    1990-01-01

    Pauli's dreamt of a new metaphysics that would eliminate the Cartesian divide between matter and spirit, and accomplish a re-enchantment of Nature. Pauli's vision it would appear, has not been widely shared, outside of the realms of popular science. It is not surprising that someone of Pauli's persuasion, like Laurikainen, should regard this neglect as the result of a conspiracy. In a more dispassionate light, it is appropriate to take Pauli's radical proposals as a measure of the profound sense of wonder he felt at the strange, shadowy world of the quantum where classical certitudes desert us. In attempting to delineate a metaphysics radically different from that underlying classical physics, Pauli took on a conceptual challenge of immense magnitude. This enterprise itself, regardless of its success or failure, offers testimony of Pauli's stature as a philosopher-physicist. (author). 31 refs

    Full Text Available In this research, it was aimed to determine the deficiencies of secondary school fifth- and sixth-grade students on word problem solving and their failures in this process. For this purpose, four separate word problems were asked to the students and their written answers were taken at the implementation process. The analysis of the data suggests that a significant part of these secondary school students had deficiencies during word problem solving and their failures in this process. Moreover, these deficiencies and failures were reported to be related to the understanding of word problems and the planning for solutions in the solving process. In addition, it was found that the fifth- and sixth- grade students rarely attempted to use drawing in order to solve the word problems. They mostly had deficiencies in deciding which arithmetic operations to be used while approaching the problems and they had failures at their arithmetic operations. [Bu araştırmada, ortaokul beşinci ve altıncı sınıf öğrencilerinin sözel problemleri çözme konusundaki yetersizlikleri ile bu tür problem çözümlerindeki hatalarının belirlenmesi amaçlanmıştır. Bu amaçla, beşinci ve altıncı sınıf öğrencilerine dört farklı sözel problem sorulmuş ve cevapları yazılı olarak alınmıştır. Ulaşılan verilerin analizi, ortaokul öğrencilerinin önemli bir kısmının sözel problemleri çözme konusunda yetersizlikleri ve problem çözümlerinde hataları bulunduğunu göstermiştir. Ayrıca, bu yetersizlik ve hatalarının çoğunlukla problem çözme süreci kapsamında problemin anlaşılması ve çözüm için plan yapma aşamalarına ilişkin olduğu belirlenmiştir. Bununla birlikte, beşinci ve altıncı sınıf öğrencilerinin sözel problem çözümlerinde şekil çizmeye çok az yer verdikleri anlaşılmıştır. Öğrenciler problemlere yaklaşımlarında kullanacakları uygun aritmetik işlemlere karar vermede çoğunlukla yetersiz

    Bulk heterojunction organic solar cell devices were fabricated using the spray deposited poly [N-9″-hepta-decanyl-2,7-carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′, 3′-benzothiadiazole)]/[6,6]-phenyl-C61-butyric acid methyl ester blend active layer. The spray coating parameters such as spraying time, substrate-nozzle distance for the deposition of active layers were analyzed. Optical absorption of the active layers was analyzed using UV–visible spectral studies in the wavelength range from 300 to 800 nm. The surface morphology of the active layers deposited with different parameters was examined using atomic force microscopy. Surface morphology of the active layers deposited with the substrate-nozzle distance of 20 cm and for 20 s shows smooth morphology with peak-valley value of 4 nm. The devices fabricated using the selected active layer show overall power conversion efficiency of 1.08%. - Graphical abstract: Current–voltage (J–V) characteristics of spray deposited PCDTBT:PC 61 BM active layer based solar cell device under illumination of AM 1.5 G, 100 mW/cm 2 . Highlights: ► Organic solar cells were fabricated using a spray deposited PCDTBT:PC61BM active layer. ► The active layers deposited with spray conditions show flat morphology. ► Using the selected active layers power conversion efficiency of 1.08% is obtained.

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available This article deals with the concept 'particle', specifically with the German notion of 'Abtönungspartikel'. These pragmatic or modal particles were first discussed in contemporary German grammars by Harald Weydt. Although the concept itself is clear, it is difficult to include such a category in existing grammars, as is shown by the treatment of such inflexible words in different editions of the standard German grammar, Der Duden. It seems difficult to formulate a description of the word class 'particle' in such a way that it includes pragmatic particles as well as other kinds of particles, such as focus particles. This problem is not new, and I also discuss parallels from the history of linguistics.

  11. #AltPlanets: Exploring the Exoplanet Catalogue with Neural Networks

    Science.gov (United States)

    2017-12-01

    The launch of Kepler in 2009 brought the number of known exoplanets into the thousands, in a growth explosion that shows no sign of abating. While the data available for individual planets is presently typically restricted to orbital and bulk properties, the quantity of data points allows the potential for meaningful statistical analysis. It is not clear how planet mass, radius, orbital path, stellar properties and neighbouring planets influence one another, therefore it seems inevitable that patterns will be missed simply due to the difficulty of including so many dimensions. Even simple trends may be overlooked if they fall outside our expectation of planet formation; a strong risk in a field where new discoveries have destroyed theories from the first observations of hot Jupiters. A possible way forward is to take advantage of the capabilities of neural network autoencoders. The idea of such algorithms is to learn a representation (encoding) of the data in a lower dimension space, without a priori knowledge about links between the elements. This encoding space can then be used to discover the strongest correlations in the original dataset.The key point is that trends identified by a neural network are independent of any previous analysis and pre-conceived ideas about physical processes. Results can reveal new relationships between planet properties and verify existing trends. We applied this concept to study data from the NASA Exoplanet Archive and while we have begun to explore the potential use of neural networks for exoplanet data, there are many possible extensions. For example, the network can produce a large number of 'alternative planets' whose statistics should match the current distribution. This larger dataset could highlight gaps in the parameter space or indicate observations are missing particular regimes. This could guide instrument proposals towards objects liable to yield the most information.

    The criticality analysis in a pyroprocessing facility is very important element for the R and D and the facility design in terms of the determination of batch size of the sub-processes as well as facility safety. Particularly, the determining the batch size is essential at the beginning stage of the R and D. In this report, the criticality analysis was carried out for the subprocesses such as voloxidation, electrolytic reduction, electrorefining and electrowinning process in order to estimate the maximum batch size of each process by using Monte Carlo code (MCNP4/C2). On the whole, the criticality problem could not give a big effect on the batch sizes in the voloxidation, electrolytic reduction and electrorefining. However, it was resulted that permissible amount of nuclear material to prevent the criticality accident in the electrowinning process was about 10kgHM

  1. Musical rhythm spectra from Bach to Joplin obey a 1/f power law.

    Much of our enjoyment of music comes from its balance of predictability and surprise. Musical pitch fluctuations follow a 1/f power law that precisely achieves this balance. Musical rhythms, especially those of Western classical music, are considered highly regular and predictable, and this predictability has been hypothesized to underlie rhythm's contribution to our enjoyment of music. Are musical rhythms indeed entirely predictable and how do they vary with genre and composer? To answer this question, we analyzed the rhythm spectra of 1,788 movements from 558 compositions of Western classical music. We found that an overwhelming majority of rhythms obeyed a 1/f(β) power law across 16 subgenres and 40 composers, with β ranging from ∼0.5-1. Notably, classical composers, whose compositions are known to exhibit nearly identical 1/f pitch spectra, demonstrated distinctive 1/f rhythm spectra: Beethoven's rhythms were among the most predictable, and Mozart's among the least. Our finding of the ubiquity of 1/f rhythm spectra in compositions spanning nearly four centuries demonstrates that, as with musical pitch, musical rhythms also exhibit a balance of predictability and surprise that could contribute in a fundamental way to our aesthetic experience of music. Although music compositions are intended to be performed, the fact that the notated rhythms follow a 1/f spectrum indicates that such structure is no mere artifact of performance or perception, but rather, exists within the written composition before the music is performed. Furthermore, composers systematically manipulate (consciously or otherwise) the predictability in 1/f rhythms to give their compositions unique identities.

    Full Text Available Montaj Hattı Dengelemesinde, -çeşitli nedenlerle- belli iş elemanlarının birbirinden ayrılmaması ve aynı istasyona atanması istenebilir. Bu tür problemler, 'Birliktelik Kısıtları Altında Montaj Hattı Dengeleme (BKAMHD Problemi' olarak tanınmaktadır. Bu birliktelik kısıtı sayesinde, havaleli ürün imali, birlikte işlem görme gereği gibi özel isteklerden veya takım-kolaylık benzeri kaynakların ortak kullanımı düşüncesinden kaynaklanan 'konum ve bölge kısıtları' da karşılanabilmektedir. Bu tür hatlarda ayrıca, malzeme aktarma, takım ve kolaylık maliyetleri, yürüyüş mesafeleri, ayar süreleri ile tedarik süreleri de azalmaktadır. Uygulamada BKAMHD yapısındaki problemlerle yaygın olarak karşılaşılmasına karşın, bunlar üzerinde yapılan çalışmaların klasik montaj hattı dengeleme problemi ile ilgili yayınlara göre daha az olduğu görülmektedir. Bu çalışmanın amacı, özel konum kısıtları dolayısıyla-, bilinen Montaj Hattı Dengeleme yöntemlerinin uygulanamadığı büyük ölçekli bir montaj hattı için uygun bir hat dengeleme yöntemi geliştirmek ve bu yöntem ile söz konusu hattı dengelemek olmuştur. Çalışmanın başında, bu problemin çözümünde kullanılabilecek basit fakat etkili bir yol olarak tanınan 'En Büyük Aday' algoritmasında bazı değişiklikler yapılarak yeni bir yöntem geliştirilmiştir. Bu yöntemin uyarlanabilmesi için de montaj işlemlerinin yapıldığı atölyede çok yoğun bir metot ve zaman etüdü çalışması yürütmek gerekmiştir. Bu çalışma sonucunda derlenen verilerin geliştirilen yönteme uyarlanması sonucunda türetilen seçenekler değerlendirilerek karar vericiye sunulmuştur.

    ûk ve Türkiye Selçuklu devletleri ile göçebe Türkmenlerden müteşekkil bir ittifak buldular. Bunlar arasında Türkmenler, Moğolların siyasî amaçlarına ve askerî faaliyetlerine karşı en kararlı direnç noktasını oluşturmuşlardır. Gaza ülküsü gibi dinî motifler de içeren bu direniş, Türkmenlerin Anadolu’yu ısrarlı bir şekilde yurt edinme çabasının bir sonucudur. Esasen Anadolu’nun uç bölgelerine yoğun bir şekilde yerleşen Türkmenler için başka bir seçenek de kalmamıştır. Zira yarımadanın siyasî ve coğrafî sınırları onların bir başka bölgeye göçüne imkân da vermemiştir. Bunun içindir ki Türkmenlerin Anadolu’yu kararlı bir şekilde yurt edinme çabası ile Moğollara ısrarla karşı koymaları birbirini besleyen tavırlardır. Moğol ve Türkmen göçebeleri arasında uzun süren bu çatışmalar, Anadolu’da Selçuklu ve İlhanlı idaresinin çökmesiyle sonuçlanmıştır. Göçebe Türkmenler önde gelen siyasî aktörler olarak neticede Siyasal Türkmen Kimliği edinmişlerdir. XIV. asrın başlarında Anadolu’nun uç bölgelerinde ortaya çıkan Türkmen Beyliklerini kuran siyasî ve toplumsal zümrelerin bu kimliğin etkisinde oldukları görülmektedir. Örneğin Osmanlı Beyliği’nin kurucusu Osman Bey, İlhanlı hâkimiyeti altında Anadolu’da yaşanan Moğol-Türkmen çatışmasının ürünü olan siyasî yöntem, söylem ve araçları kullanmıştır.

    2006-09-15

    In the Mozart year 2006 also medicine has to deal with the music genius W.A. Mozart. It has been intensely discussed for a long time whether Mozart was poisoned, whether he deceased from a certain illness, or by self-medication and/or medical procedures. Consequently, his death caused wild speculations and adventurous assertions. Many authors assume that Mozart was a chronically ill man all his life. However, most of Mozart's described illnesses were harmless, and his unbelievable amount of work proves his extraordinary efficiency. The exact cause of death remains speculative. The story of a tall stranger dressed in somber gray who assigned Mozart to write a Requiem Mass and the circumstances of Mozart's funeral have additionally contributed to the generation of legends. However, if one gathers all known facts, there is no evidence that Mozart was murdered, and the exact cause of his death remains unclear.

    replacing the original complex pore structure of real porous media by a conceptual network. The second step consists of resolving the governing equations of the precipitation and dissolution phenomena (i.e. reactive convection diffusion equation in the conceptual 3D pore network and deducing the local reactive fluxes and the motion of the fluid-solid interface. The third step consists of updating the new pore structure and calculating the new petrophysical properties of the modified porous media. Those steps are repeated in order to mimic a given diagenetic scenario. Finally, the multiphase flow properties of the current porous media are calculated. The impact of one diagenetic cycle of dissolution and precipitation on the pore networks’ heterogeneity and consequently on the petrophysical properties (i.e. porosity and permeability and multiphase flow properties (i.e. relative permeability and capillary pressure have been investigated. The permeability and porosity evolution during a given diagenetic cycle are calculated and analyzed as a function of the relevant dimensionless numbers (Peclet and Damköhler numbers that characterize the flow and reaction regime. The correlation between these numbers and the dissolved/precipitated layer thickness distribution is investigated. This work contributes to improve the understanding of the impact of dissolution and precipitation on permeability and porosity modification. Using the PNM approach, multiphase flow properties and permeability-porosity relationship have been determined for different reactive flow regimes. These relationships are relevant input data to improve the quality of reservoir simulation predictions.

    This final report for the Swiss Federal Office of Energy (SFOE) discusses the experience gained with a small hydro-power installation in Derendingen, Switzerland. This unique 'micro' installation uses an archimedian screw to produce 6.8 kW of power from a head of 1.15 m and a through-flow of 800 - 1000 litres per second. Optimisation of the project is discussed as are the effects of changing water levels above and below the screw. Winter operation is described and the mounting of gratings necessary to avoid the intake of debris is discussed. Fish-passes are looked at and the effort required for maintenance is compared with that for other types of installations. An accident that occurred is analysed and the results of energy-efficiency measurements made on the installation are presented. The report is rounded off with an evaluation of the plant's performance and a review of future work to be done.

    Full Text Available Some studies have found that subjects give higher preference ratings and clearer emotional descriptions to pieces with the tempo/mode pairs fast/major and slow/minor. If these findings are true, one might expect to find a predominance of fast/major and slow/minor pairings in musical literature. This study looks for just such a trend in the canonical work of J.S. Bach’s Well Tempered Clavier. Books 1 and 2 together contain 24 Major Preludes, 24 Minor Preludes, 24 Major Fugues and 24 Minor Fugues. We use four different measurements of fast/slow tempo based both on elements within the musical notation as well as the interpretive markings of four different music editors: 1. Attacks Per Beat (APB – measures the number of subdivisions of each piece 2. Attacks Per Minute (APM – is the APB of a piece multiplied by the editor’s metronome marking 3. Time Signature Distribution and 4. Editor’s Tempo Distribution. We find a significant amount of fast/major and slow/minor pairings in Book 1 but not in Book 2.

  1. Cueing musical emotions: An empirical analysis of 24-piece sets by Bach and Chopin documents parallels with emotional speech

    Full Text Available Acoustic cues such as pitch height and timing are effective at communicating emotion in both music and speech. Numerous experiments altering musical passages have shown that higher and faster melodies generally sound happier than lower and slower melodies, findings consistent with corpus analyses of emotional speech. However, equivalent corpus analyses of complex time-varying cues in music are less common, due in part to the challenges of assembling an appropriate corpus. Here we describe a novel, score-based exploration of the use of pitch height and timing in a set of balanced major and minor key compositions. Our corpus contained all 24 Preludes and 24 Fugues from Bach’s Well Tempered Clavier (book 1, as well as all 24 of Chopin’s Preludes for piano. These three sets are balanced with respect to both modality (major/minor and key chroma (A, B, C, etc.. Consistent with predictions derived from speech, we found major-key (nominally happy pieces to be two semitones higher in pitch height and 29% faster than minor-key (nominally sad pieces. This demonstrates that our balanced corpus of major and minor key pieces uses low-level acoustic cues for emotion in a manner consistent with speech. A series of post-hoc analyses illustrate interesting trade-offs, with

  2. Variety in Performance: A comparative Analysis of Recorded Performances of Bach's Sixth Suite for Solo Cello from 1961 to 1998

    2011-08-01

    Full Text Available There exists a commonly held belief amongst musicologists that there has been a ―general globalisation of styles‖ within recorded performances of the latter half of the twentieth century. For many, this is evidenced by an increased interaction between mainstream (MS and historically informed performance (HIP practices as well as a general decrease in the diversity of performances. Through a comparative aural and software-assisted analysis and measurement of performance features such as tempo, rhythmic flexibility, vibrato, portamento, bowing, and articulation in key interpretations of Bach‘s Suite No. 6 for Solo Cello recorded in between 1961 and 1998, this study investigates the relationship between MS and HIP performances in the latter half of the 20th century. By limiting analyses to those performers who have made two recordings during the designated period (Tortelier, Starker, Bylsma, Ma, Wispelwey, it has been possible to identify overarching trends and individual differences. These have been examined with reference to their broader social and cultural context in order to test commonly held musicological assumptions about the modernist and postmodernist foundations of performances from this era. The results indicate that by the 1990s increased interaction between MS and HIP practices has resulted in a wider variety of differing performances and that this can be seen to be symptomatic of the postmodern condition that has become prevalent since the last decade of the 20th century.

La investigación científica, también en arquitectura, en 1966 acumulaba más de cincuenta años de continuada práctica.El cruce de modelos que se muestra en sus más de 300 páginas, más que un extenso repertorio a modo de guía sobre viviendas, edificios y formas de ciudad y cuyo interés sería relativo, nos ofrece hoy múltiples instantáneas de formas de vida; algunas de ellas permanecen vigentes mientras otras, han sido convenientemente alteradas. Se refiere de esta manera el laboratorio de arquitectura más extenso conocido en constante transformación: el tiempo transcurrido desde la aparición del libro da a esta investigación sobre modelos residenciales una necesaria y conveniente continuidad.

  17. Liner velocity, current, and symmetry measurements on the 32 MA flux compression generator experiment ALT-1

    CERN Document Server

    Clark, D A; Rodríguez, G; Tabaka, L J

    2001-01-01

    Summary form only given, as follows. A flux compression generator based pulse power system, designed, built, and fielded by a Russian team at the All Russian Scientific Research Institute of Experimental Physics (VNIIEF), was used to successfully drive an aluminum liner to velocities greater than 10 km/sec. The experiment objective was to demonstrate performance of a precision liner implosion at Atlas current of 30 MA or greater. Diagnostics to measure liner performance were an essential part of the experiment. An experimental team from Los Alamos National Laboratory (LANL) provided a suite of diagnostics to measure liner performance. Three diagnostics were fielded. 1. a velocity interferometer (VISAR) to continuously measure the liner inner surface velocity from throughout the entire range of travel. 2. Two Faraday rotation devices to measure liner current during the implosion. 3. Sixteen fiber optic impact pins to record liner impact time and provide axial and azimuthal symmetry information. All diagnostics...

    Steinmayr, Johann; Müller, Isolde; Posch, Thomas

    2011-08-01

    We give a brief overview of the development of astronomical research at the University of Graz from the 16th to the 18th century. This period is intimately connected to the activities of the Jesuit Order and to the counter-reformation in Inner Austria (a territory roughly corresponding to today's Styria, Carinthia, Slovenia and the County of Görz in Italy). Since the opening of the University in 1585, several Jesuits achieved distinction as mathematicians, physicists and astronomers in Graz. Among them are Paul Guldin, who corresponded with Johannes Kepler and died in Graz in 1643, as well as Leopold Biwald and Karl Tirnberger. Between 1745 and 1774, the Jesuit University of Graz also had a chair of astronomy and an observatory. The chair and the observatory were well endowed at the beginning, but later on neglected by their former funders and closed down after less than 30 years. Efforts to re-establish an observatory at Graz at the beginning of the 19th century failed. They were successful only towards the end of the 19th century, which is however a period beyond the scope of the present paper.

  9. Advanced limiter test (ALT-I) in the TEXTOR tokamak - concept and experimental design

    International Nuclear Information System (INIS)

    Conn, R.W.; Grotz, S.P.; Prinja, A.K.

    1983-01-01

    The concept and experimental design of a pump-limiter for the TEXTOR tokamak is described. The module is constructed of stainless steel with a compound curvature head designed to limit the maximum heat flux to 300 W/cm 2 . The head is made of TiC-coated graphite containing a variable aperture slot to admit plasma to a deflector plate for ballistic pumping action. The assembly is actively pumped using Zr-Al getters with an estimated hydrogen pumping speed of 2x10 4 1/s. The aspect ratio of the pump duct and the length of the plasma channel are both variable to permit study of plasma plugging, ballistic scattering, and enhanced gas conduction effects. The module can be moved radially by 10 cm to permit its operation either as the primary or secondary limiter. Major diagnostics include Langmuir and solid state probes, bolometers, infrared thermography, thermocouples, ion gauges, manometers, and a gas mass analyzer. (author)

    Full Text Available În legătură cu reformarea sistemului judiciar şi schimbările intervenite în viaţa social-politică a statului nostru, prin­cipiul contradictorialităţii a obţinut o nouă rezonanţă din considerentul că reforma judiciară şi de drept este legată direct de contradictorialitate. Reforma legii procesual penale trebuie să fie fundamentată pe o temelie teoretică solidă. Contra­dictorialitatea, însă, în calitate de noţiune juridică, este insuficient cercetată în doctrina dreptului procesual penal. La ziua de azi, specialişti notorii în domeniul dreptului procesual penal analizează şi studiază importanţa fundamentelor şi principiilor de bază ale procesului penal şi, în primul rând, contradictorialitatea acestuia. Legea procesual penală a Republicii Moldova cunoaşte o evoluţie şi dezvoltate în sensul democratizării şi lărgirii începuturilor contradictoriale în înfăptuirea justiţiei. Aceasta e şi firesc, deoarece contradictorialitatea are o importanţă enormă pentru întregul sistem al procesului penal, determinând în mare parte statutul juridic şi raporturile dintre participanţii la procesul penal, precum şi relaţiile juridice stabilite între participanţii la acest proces şi instanţa de judecată. CONTRADICTION AND ITS CORRELATION WITH OTHER PRINCIPLES OF THE CRIMINAL PROCEEDINGIn connection with the judiciary system reforming and changes in socio-political life of our state, the adversarial principle has gained a new resonance on the grounds that the judicial and legal reform is directly linked to adversariality. The reform of the criminal procedure law must be based on solid theoretical foundation. However, adversariality, as legal concept, is not enough investigated in the doctrine of the criminal procedure law. Currently, notorious specialists in the field of criminal procedure law examine and study the importance of fundamentals and basic principles of the criminal process and, primarily, its adversariality. The Criminal Procedure Law of the Republic o fMoldovais advancing and developing through democratization and widening of adversariality beginnings in justice rendering. This is natural and, as adversariality has enormous significance for the entire system of criminal proceedings, largely determining the legal status and relations between the participants in criminal proceedings and the legal relationships between the parties to the proceedings and the court.

    2016-01-01

    Warda and Strohmayer from Thuringia were among the first German physicians who developed an interest in Freuds theory and therapeutic method around 1900. Their contributions reflect the influence of Otto Binswanger, professor of psychiatry in Jena, a representative of the "psychological direction" in psychiatry which in the beginning was relatively receptive to Freud. The paper discusses their rapprochement to, and detachment from, the Freudian school, including also the work of a third young physician: Ludwig Binswanger, Otto's nephew, who was active in Jena at the same time. It points to certain factors contributing to the increasing rejection Freud met in academic circles which have been underrated to date: (1) the transformation of psychoanalysis into an art of interpretation; (2) the introduction of transference. Both factors which were elaborated by Freud as essentials of his theoretical and practical approach around 1900 and published in 1904/05, undermined the claim of academic medicine to objectivity. The paper describes how psychoanalysis officially abandoned the scientific standards of contemporary medicine at the Weimar congress in 1911, at the same time as Warda and Strohmayer left the Freudian group.

    Questing one's personal identity and developing a coherent representation of oneself, the other and the world are major tasks in adolescence. Research showed that a satisfactory resolution of the crisis of adolescence can be favoured by psychological counselling based on artistic mediations. The objective of this study consisted in exploring the effect of music on the pictorial expression of a non clinical sample of female adolescents (N=157) aged from 17 to 28 years. We analysed free drawings realised by the test group with the help of a rating scale constructed in a phenomenological and structural perspective (Schiltz, 2006). The adolescents painted under musical induction. We proposed three different styles of music, i.e. baroque music (Georg Friedrich Händel and Johann Sebastian Bach), classical music (Wolfgang Amadeus Mozart and Ludwig van Beethoven) and polish ethnical music (Kapela ze Wsi Warszawa-Warsaw Village Band). By using non parametric inferential and multi dimensional statistics, we could show that structural characteristics of music styles lead to differences in formal and content variables on the rating scales for the pictures. The results of our exploratory study open some tracks for future research. It would be pertinent to enlarge the population to other categories of age and to investigate the influence of gender.

    Full Text Available The present article deals with the process of elaborating guitar fingerings for Johann Sebastian Bach’s Ciaccona BWV 1004 (original for violin. The aim was to develop a left-hand fingering capable of reflecting the musical intentions of the performers and authors of this article. To this end, a model of analysis was established, in which the musical texture is divided and classified, based on a set of theoretical parameters (melodic, harmonic, motivic and polyphonic. By analyzing the fingerings used in transcriptions from guitarists Andrés Segovia, Abel Carlevaro, Kazuhito Yamashita and Stanley Yates, and comparing them with our own suggestions, we conclude that the performer has autonomy to challenge a fingering provided by the editor, as it reflects only the musical or technical decisions from a specific performer, and these decisions are also subjected to change.

    Interest in stimulus responsive materials and polymers has grown over the years, having shown great promise in a diverse set of applications. For drug delivery, stimulus-responsive polymers have been shown to encapsulate therapeutic cargo such as small molecule drugs or proteins, deliver them to specific locations in the body, and release them so that they can induce a therapeutic effect in the patient. Most hydrolytically degradable polymers are synthesized via nucleophilic, anionic, or cationic polymerization, which generally requires protection of nucleophilic or protic side chains prior to polymerization. Here, we report the synthesis of novel, alternating copolymers of sulfur dioxide and O-vinyl carbamate monomers that boast excellent functional group tolerance and pH-dependent instability. Alternating copolymers were synthesized containing pendant functionalities such as alcohol, carboxylic acid, ester, and azide without deprotection or post-polymerization modification. The copolymers were then formulated via nanoprecipitation into polymer nanoparticles capable of encapsulating small molecule dyes. The polymer nanoparticles were found to degrade rapidly at pH > 6 and were stable even in highly acidic conditions. Based on this observation, a proof-of-concept study for mucosal delivery was performed in polymer nanoparticles entrapped in a mucus model. At pH 8 the diffusion of encapsulated dye was found to be similar to free dye, while at pH 5 the diffusion coefficient was an order of magnitude lower. Cell viability was retained at 200 µg/mL particles after 24 h incubation. These polymers thus show promise as highly customizable scaffolds for mucosal drug delivery.

    This preliminary project for the Swiss Federal Office of Energy (SFOE) presents a project which proposes the construction of a new small hydro plant in Niedergoesgen/Gretzenbach, Switzerland, that is to make use of the waters of the old river Aare. The project proposes the construction of a new, 350 kW plant at the site of an existing sill across the old river that originally formed part of a water-power installation given up in 1917. The existing parts of the old installation are described and the legal situation concerning water rights and land ownership are examined. Three variants for a new installation are described. Technical figures and energy-production estimates for a new installation are discussed. Ecological aspects are examined, as are the recreational aspects of the river at this location. Cost estimates and economic viability are discussed.

    The use of microsurgery in the management of burn sequelae is not a new idea. According to the properties of various types of free flaps different goals can be achieved or various additional procedures have to be combined. We report the comparison of two different free flaps on a single patient for reconstruction of both upper extremities for burn sequelae. A 1-year-old child sustained severe burns on both hands, arms and thorax and was initially only treated conservatively. This resulted in severe contractures. At the age of 4-years a free gracilis flap was selected for reconstruction of his left hand and a free anterolateral thigh flap for the right hand. We noticed a better functional and esthetic result for the gracilis flap associated with a shorter operative time and a minor donor site morbidity. The intraoperative technique and time, postoperative complications, functional and esthetic results and donor site morbidities were studied in the two types of flaps chosen. A review of literature was also performed. Our experience reported a better success of the gracilis muscle flap covered with a split skin graft compared to the anterolateral thigh flap in the reconstruction of hand function after severe burn sequelae.

    Currently, developing a stable nanocarrier with high cellular internalization and low toxicity is a key bottleneck in nanomedicine. Here, we have developed a successful method to covalently conjugate poly(methyl vinyl ether-co-maleic acid) (PMVE-MA) copolymer on the surface of (3-aminopropyl)triethoxysilane-functionalized thermally carbonized porous silicon nanoparticles (APSTCPSi NPs), forming a surface negatively charged nanovehicle with unique properties. This polymer conjugated NPs could modify surface smoothness, charge, and hydrophilicity of the developed NPs, leading to considerable improvement in the colloidal and plasma stabilities via enhanced suspensibility and charge repulsion. Furthermore, despite the surface negative charge of the polymer-conjugated NPs, the cellular internalization was increased in both MDA-MB-231 and MCF-7 breast cancer cells. These results provide a proof-of-concept evidence that such polymer-based PSi nanocomposite can be extensively used as a promising candidate for intracellular drug delivery. © 2014 WILEY-VCH Verlag GmbH & Co.

    Full Text Available In this study chelating resins have been considered to be suitable materials for the recovery of Copper (II ions in water treatments. Furthermore, these modified resins were reacted with 1,2-diaminoethane in the presence of ultrasonic irradiation for the preparation of a tridimensional chelating resin on the Nano scale for the recovery of Copper (II ions from aqueous solutions. This method which is used for removing and determining Copper (II ions using copolymers derived resins of poly (styrene-alternative-maleic anhydride (SMA and atomic absorption spectroscopy. The method is simple, sensitive, inexpensive and fast. The various parameters such as pH, contact time, concentrations of metal ions, mass of resin, and agitation speed were investigated on adsorption effect. The adsorption behavior of Copper (II ions were investigated by the synthesis of chelating resins at various pHs. The prepared resins showed a good tendency for removing the selected metal ions from aqueous solution, even at an acidic pH. Also, the prepared resins were examined for the removal of Copper (II ions from real samples such as industrial wastewater and were shown to be very efficient at adsorption in the cases of Copper (II ions. The pseudo-first-order, pseudo-second-order, and intra-particle diffusion kinetics equations were used for modeling of adsorption data and it was shown that pseudo-second-order kinetic equation could best describe the adsorption kinetics. The intra-particle diffusion study revealed that external diffusion might be involved in this case. The resins were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray diffraction analysis.

    KAUST Repository

    Poelking, Carl

    2013-01-31

    We establish a link between the microscopic ordering and the charge-transport parameters for a highly crystalline polymeric organic semiconductor, poly(2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene) (PBTTT). We find that the nematic and dynamic order parameters of the conjugated backbones, as well as their separation, evolve linearly with temperature, while the side-chain dynamic order parameter and backbone paracrystallinity change abruptly upon the (also experimentally observed) melting of the side chains around 400 K. The distribution of site energies follows the behavior of the backbone paracrystallinity and can be treated as static on the time scale of a single-charge transfer reaction. On the contrary, the electronic couplings between adjacent backbones are insensitive to side-chain melting and vary on a much faster time scale. The hole mobility, calculated after time-averaging of the electronic couplings, reproduces well the value measured in a short-channel thin-film transistor. The results underline that to secure efficient charge transport in lamellar arrangements of conjugated polymers: (i) the electronic couplings should present high average values and fast dynamics, and (ii) the energetic disorder (paracrystallinity) should be small. © 2013 American Chemical Society.

    2007-12-01

    Full Text Available Parallel with the initiation of an integrated curriculum at the Medical University of Graz a virtual learning environment was implemented, designated as Virtual Medical Campus (VMC. Several financial support projects made the development of the VMC and its enhancements possible. Learning objects are granular and strictly equipped with a set of metadata conforming the SCORM 2004 2nd edition-standard and are therefore reusable and exchangeable with other study courses or e-Learning-systems. Simple usability allows authors the intuitive creation of content, which may be enriched with interactive and tutorial systems using several built in authoring tools like web-based-training or a Virtual Microscope. In 2005 more than 3300 students applied for human medicine at the Medical University of Graz and it was decided to give a virtual term with a selection process at the end of it.More than 1 million accesses to learning objects and 257,000 web-based-trainings were handled without a single breakdown. This unique interim solution of a virtual term demonstrated the capacity of the VMC-system and the organisational possibility to intercept rushes of application using e-Learning. In the meanwhile the VMC Graz provides 13 study courses at four universities in two different European countries and two international postgraduate programs. The technical development aims at Web 3.0 – “Semantic Web” and the further expansion of co-operations is a present and future strategy.

    The hydrodynamics of the groundwater system of the upland granito-gneissic plateau of Madagascar is governed by the structure of the underlying aquifer. In the alteritic interfluves, the aquifer has two layers; the peat aquifer is multilayered. Groundwater levels and spring discharges observed over 3 successive years distinguish between two different types of hydraulic behaviour. (1) Under the interfluves, unconfined conditions are found in allochtonous weathered material, and semi-confined conditions in the autochtonous weathered basement. These two systems are separated by a semi-permeable clay layer. The first system responds rapidly to rainfall (approximately 15 days) whereas the second system responds more slowly (approximately 3 months). This leads to a vertical flux between the two aquifers, the direction of which depends on the season; at the beginning of the wet season the flux is downwards, but during the later part of the season the direction reverses. (2) In the low-lying regions, where sequences are superimposed, the direction of the vertical flow changes several times over a year. At the beginning of the wet season the flux is downwards, it reverses at the end of the season. A downwards flux is then observed towards the second part of the dry season. Such behaviour is only observed in the lowest third of the catchment where permeable silts take the place of less permeable peat. This pattern of fluxes suggests a close relationship between surface water and groundwater regimes, and has a major influence on the individual water balances of the two systems.

    The exploration of hydrocarbons is confronted with the penetration into ever larger depths with increasingly more unfavorable reservoir characteristics. That means lower porosities and permeabilities. The geometry of a tectonic formation is a substantial size for the gap formation. It is expected that the observable curvature of a rock formation stands in direct connection with porosity and permeability of the rock. Under this aspect, the behaviour of a rock formation is examined at the demand above the yield strength by means of theoretical approaches from fracture mechanics. The author of the available contribution comes to the result: Secondary porosity is directly proportional to the curvature of the formation. In contrast to this, the secondary permeability is proportional to the third power of the curvature of the formation.

    UV and γ-ray resistance of transparent polymers obtained by radical polymerization of maleic and fumaric acid derivatives, i.e., an alternating copolymer of N-methylmaleimide and isobutene (PMI) and poly(diisopropyl fumarate) (PDiPF), was investigated. Transmittance in UV and visible regions of these polymers were examined after UV irradiation and compared with the results for poly(methyl methacrylate) (PMMA) and polycarbonate (PC) as conventional transparent polymers. The order of stability toward UV irradiation was PMMA≈PDiPF>PMI>>PC, deduced from changes in the transmittance of 380 nm light. Tensile mechanical properties, such as elastic modulus, maximum strength, and elongation values of PMI, PDiPF, and PMMA were also investigated after UV and γ-radiation. UV irradiation induced the side chain scission of PMI and PDiPF via Norrish I type reaction as well as crosslinking by combination between formed polymer radicals, leading to deterioration in their optical and mechanical properties. γ-radiation induced significant changes in molecular weight and mechanical properties of the polymers. In conclusion, PMI exhibited unchanged mechanical properties and PDiPF maintained its high transparency under various irradiation conditions.

    One of the design features which yet offers interesting margins for performance optimization of cable-in-conduit conductors (CICCs), is their geometry. For relatively small size Nb{sub 3}Sn CICCs, operating at high electromagnetic pressure, such as those for the EDIPO project, it has been experimentally shown that a design based on a rectangular layout with higher aspect ratio leads to the best performance, especially in terms of degradation with electromagnetic loads. To extend this analysis to larger size Nb{sub 3}Sn CICCs, we manufactured and tested, in the SULTAN facility, an ITER toroidal field (TF) cable, inserted into a thick stainless steel tube and then compacted to a high aspect ratio rectangular shape. Besides establishing a new record in Nb{sub 3}Sn CICC performances for ITER TF type cables, the very good test results confirmed that the conductor properties improve not only by lowering the void fraction and raising the cable twist pitch, as already shown during the ITER TFPRO and the EDIPO test campaigns, but also by the proper optimization of the conductor shape with respect to the electromagnetic force distribution. The sample manufacturing steps, along with the main test results, are presented here.

    Full Text Available Die Arbeit geht der Frage nach, wie sich das österreichische System der Langzeitbetreuung älterer Menschen mit Augenmerk auf die nachhaltige Solidarität zwischen Generationen u.a. im Vergleich mit anderen europäischen Ländern gestaltet. Besonderes Augenmerk wird dabei auf Finanzierungs-, Versorgungs- und Governance-Strukturen gelegt, sowie auf den Vergleich mit anderen sozialpolitischen Bereichen (Familienleistungen, Kinderbetreuung. Österreich hat im internationalen Vergleich ein relativ großzügiges System der öffentlichen Unterstützung älterer Menschen, das stark auf Geldleistungen aufbaut. Dies gilt auch für die Langzeitbetreuung, wo eine große Anzahl pflegebedürftiger Menschen erreicht wird, diese aber pro Kopf eher wenig erhalten. Die Pflegeleistungen werden aus allgemeinen Steuermitteln sowie Kostenbeiträgen von NutzerInnen finanziert, was bedeutet, dass die Finanzierung primär über die Besteuerung von Arbeitseinkommen erfolgt. Unterschiedliche Kostenbeitrags- und Regressregelungen auf Bundesländerebene führen zudem zu großen Differenzen in der finanziellen und faktischen Verantwortung von Familien, insbesondere jüngerer Generationen, die Pflege und Betreuung pflegebedürftiger Angehöriger sicherzustellen. Es folgt, dass die Einführung vermögensbezogener „Pflegesteuern“ zu mehr Ausgewogenheit in den solidarischen Elementen des Pflegesystems beitragen könnte – nicht nur aus Generationensicht. Der flächendeckende Ausbau von Pflege- und Betreuungsdiensten und bundesweit einheitliche Regelungen zu privaten Kostenbeiträgen stellen zudem eine Voraussetzung dafür dar, dass Solidarität zwischen den Generationen unabhängig von sozialer Schicht und Wohnort beurteilt werden kann.

    For hundreds of years, slated roofs and walls were the characteristic feature of the Thuringian-Franconian boundary region, where the ''Schieferstrasse'' - the road of historical houses with slated roofs and walls - is a major tourist attraction. Today, owners of buildings are interested in technologies orientated towards the future. After restoration of a single-family home at Lehestenbuilt in 1650, modern solar modules installed on the roof and combined with traditionally-looking aluminium roof tiles by Prefa make an aesthetically pleasing picture.

    Triassic basalt of the Middle Atlas has been subject to metamorphic transformation then weathering. Occurrence in both metabasalt and saprolite of ubiquitous clay minerals, such as smectite and mixed layers chlorite-smectite, makes it difficult to distinguish between the two alteration facies and explains the interest of complementary sources of information. In the Bhallil weathering profile, petrographical and mineralogical analyses of primary igneous minerals and their alteration products coupled with Fe oxidation state determination in clay fractions allow to identify three alteration facies: ( i) metamorphic basalt, where iron occurs mainly as the ferrous form; ( ii) the lower part of saprolite, where iron is partially oxidized to its ferric form; ( iii) the upper part of saprolite, where iron is completely oxidized.

    Diffuse large B-cell lymphoma (DLBCL) is the most common B-cell lymphoma subtype, and the Epstein-Barr virus (EBV)-positive subtype of DLBCL is known to show a more aggressive clinical behavior than the EBV-negative one. BTB and CNC homology 2 (BACH2) has been highlighted as a tumor suppressor in hematopoietic malignancies; however, the role of BACH2 in EBV-positive DLBCL is unclear. In the present study, BACH2 expression and its significance were studied in 23 EBV-positive and 43 EBV-negative patient samples. Immunohistochemistry revealed BACH2 downregulation in EBV-positive cases (P < 0.0001), although biallelic deletion of BACH2 was not detected by FISH. Next, we analyzed the contribution of BACH2 negativity to aggressiveness in EBV-positive B-cell lymphomas using FL-18 (EBV-negative) and FL-18-EB cells (FL-18 sister cell line, EBV-positive). In BACH2-transfected FL-18-EB cells, downregulation of phosphorylated transforming growth factor-β-activated kinase 1 (pTAK1) and suppression in p65 nuclear fractions were observed by Western blot analysis contrary to non-transfected FL-18-EB cells. In patient samples, pTAK1 expression and significant nuclear p65, p50, and p52 localization were detected immunohistochemically in BACH2-negative DLBCL (P < 0.0001, P = 0.006, and P = 0.001, respectively), suggesting that BACH2 downregulation contributes to constitutive activation of the nuclear factor-κB pathway through TAK1 phosphorylation in BACH2-negative DLBCL (most EBV-positive cases). Although further molecular and pathological studies are warranted to clarify the detailed mechanisms, downregulation of BACH2 may contribute to constitutive activation of the nuclear factor-κB pathway through TAK1 activation. © 2017 The Authors.

  18. Epigenetic silencing of BTB and CNC homology 2 and concerted promoter CpG methylation in gastric cancer.

    BTB and CNC homology 2 (BACH2) is a lymphoid-specific transcription factor with a prominent role in B-cell development. Genetic polymorphisms within a single locus encoding BACH2 are associated with various autoimmune diseases and allergies. In this study, restriction landmark genomic scanning revealed methylation at a NotI site in a CpG island covering the BACH2 promoter in gastric cancer cell lines and primary gastric tumors. Increased methylation of the BACH2 promoter was observed in 52% (43/83) of primary gastric tumors, and BACH2 hypermethylation was significantly associated with decreased gene expression. Treatment with 5-aza-2'-deoxycytidine and/or trichostatin. A restored BACH2 expression in BACH2-silenced gastric cancer cell lines, and knockdown of BACH2 using short hairpin RNA (i.e. RNA interference) increased cell proliferation in gastric cancer cells. Clinicopathologic data showed that decreased BACH2 expression occurred significantly more frequently in intestinal-type (27/44, 61%) compared with diffuse-type (13/50, 26%) gastric cancers (P<0.001). Furthermore, BACH2 promoter methylation paralleled that of previously identified targets, such as LRRC3B, LIMS2, PRKD1 and POPDC3, in a given set of gastric tumors. We propose that concerted methylation in many promoters plays a role in accelerating gastric tumor formation and that methylated promoter loci may be targets for therapeutic treatment, such as the recently introduced technique of epigenetic editing.
