Delay-Minimizing Capacity Allocation in an Infinite Server-Queueing System
Authors: Hassin Refael , Ravner Liron
Published: March 2019

We consider a service system with an infinite number of exponential servers sharing a finite service capacity. The servers are ordered by their speed, and arriving customers join the fastest idle server. A capacity allocation is an infinite sequence of service rates. We study the probabilistic properties of this system by considering overflows from subsystems with a finite number of servers. Several stability measures are suggested and analyzed. The tail of the series of service rates that minimizes the average expected delay (service time) is shown to be approximately geometrically decreasing. We use this property to approximate the optimal allocation of service rates by constructing an appropriate dynamic program.
Current thinking on caring for patients with a wound: a practical approach
Authors: Annesley Sarah H
Published: March 2019

Wound care is increasingly nurse led. This article describes the types and causes of wounds, the six domains needed for systematic wound assessment and the principles nurses can apply to ensure evidence-based wound care. The author argues for the importance of a patient-focused approach in the care of people with chronic and acute wounds. It highlights, when specialist referral may be needed and presents a case study explaining the difficulties of managing a patient with a wound at the end of life. Nurses care for people with wounds in a broad range of clinical settings and it is a real challenge to provide optimum patient outcome (wound healing) and a positive patient experience.

A multinational evaluation assessing the relationship between peristomal skin health and health utility
Authors: Nichols Thomas , Goldstine Jimena , Inglese Gary
Published: March 2019

Background:

irritation to peristomal skin remains one of the most prevalent ostomy-related complications influencing an individual's health status and quality of life.

Aims:

to assess the impact of damaged peristomal skin on the health utility and quality-adjusted life days (QALD) in an international adult ostomy population.

Methods:

a cross-sectional survey incorporating the SF-6D preference-based health utility index was developed to assess a random selection of post-surgical patients.

Findings:

health utility decreased with increasing skin irritation among the three geographic groups. The total mean health utility of normal peristomal skin for the three groups dropped incrementally for mild, moderate, and severe irritation. There were no differences in health utility or QALDs between the three country groups.

Conclusion:

improvement of peristomal skin health is associated with improvements to QALDs. Clinicians, caregivers and patients have the responsibility to address a critical unmet need in skin health through interventions and products designed to support healthy peristomal skin.
Considerations for the management of enterocutaneous fistula
Authors: Metcalf Christine
Published: March 2019

Enterocutaneous fistula is an abnormal connection between the gastrointestinal tract and skin. Management includes early recognition and treatment of sepsis, reducing fluid and electrolyte homeostasis, nutrition support, wound management and a carefully timed surgical procedure. A multidisciplinary approach is required for successful management of these patients with one of the most challenging and resource-demanding aspects being local control of the effluent, requiring the skill and support of the specialist stoma care nurse. The inability to contain the fistula can be a source of morbidity for the patient, as they will experience pain and severe discomfort from the skin when leakages occur. Enterocutaneous fistula can result in intestinal failure, which is often fatal if not managed correctly.
Oral health and the Millennium and Sustainable Development Goals
Authors: Crean StJohn , Batchelor Paul
Published: March 2019

The world is a complex and at times mystifying place. Sense and reason struggle for visibility among national terms of reference constructed around an individual nation’s needs, pride and (in some cases) survival. Embedded among these ‘instincts’ lurk the more menacing forces of power, influence and control. It is from such hybrid climates that the globally facing Millennium Development Goals (MDGs) and the succeeding Sustainable Development Goals (SDGs) emerged.

Published: March 2019

OBJECTIVES:

Despite encouraging data gathered in inflammatory bowel diseases (IBD) patients, Vedolizumabs' (VDZ) safety profile in pregnancy is not established.

DESIGN:

Data of 330 consecutive pregnancies with IBD was prospectively collected.

RESULTS:

Women with IBD were treated with: VDZ (n = 24), anti-tumor necrosis factors (n = 82) or conventional therapy (n = 224). Gravidity and parity were similar among the 3 groups. The VDZ group was comprised mostly of Crohn's disease patients who were all not naïve to biological treatment. They had significantly higher conception rates during active disease (P < 0.05), with fewer flares during pregnancy.

DISCUSSION:

Although further study is needed, VDZ appears of low risk during pregnancy.

Authors: Kilaru Saikiran M. , Mukamal Kenneth J. , Nee Judy W. , Oza Sveta S. , Lembo Anthony J. , Wolf Jacqueline L.
Published: March 2019

Introduction:

Little is known about the gastrointestinal manifestations or safety of endoscopy among patients with heritable connective tissue disorders such as Marfan syndrome or Ehlers-Danlos syndrome (EDS).

Methods:

We conducted an electronic cross-sectional survey nested within preexisting registries of patients with heritable connective tissue disorders and examined self-reported rates of endoscopic complications.

Results:

The rate of endoscopy-related perforation was 9.4% (95% confidence interval 2.0%–25.0%) among individuals with vascular EDS, <1% in classical and hypermobility-type EDS, and zero in Marfan syndrome (P < 0.001). Spontaneous intestinal perforation was also significantly higher in the vascular EDS group.

DISCUSSION:

Clinicians should consider noninvasive screening methods for patients with vascular EDS.
Manipulation of the Gut-Liver Axis Using Microbiome Restoration Therapy in Primary Sclerosing Cholangitis
Authors: Bajaj Jasmohan S. , Hays R. Ann
Published: March 2019

Alteration of the normal gut-liver axis is important in primary sclerosing cholangitis (PSC). Lack of effective medical therapy for PSC makes microbiome restoration an alluring therapeutic target. Allegretti et al. performed an open-label safety trial of fecal microbiota transplant (FMT) in noncirrhotic PSC patients with inflammatory bowel disease in remission on minimal therapy. FMT was safe in this population, and after FMT, there was a stable, early increase in microbial diversity and donor engraftment with mixed effects on alkaline phosphatase but no significant change in fecal bile acid profile. Further trials are needed to find whether FMT has a role to play in PSC therapy.

Published: March 2019

The needs for chicken meat have been dominated by meat from exotic broilers (bred from imported parent). The potential of local broilers chicken in Indonesia is expected to be able to provide the meat for national needs for chicken meat. The objective of this research was to determine the day-old-chick (DOC) phenotypic characteristics of chickens in Indonesia that have the potential as broilers. The phenotypic characteristics are in the form of body morphometry, visceral organ weight and small intestinal histo-morphology. The chickens used were the DOC type of exotic Broiler, Kampung, exotic male Layer, KUB-1 and Pelung. A total of 125 chickens consisting of 25 chickens of each strain at posthatched age were observed for its body morphometry and its visceral organ weight, and small intestinal histo-morphology. The observed data were then analyzed by similarity analysis using MVSP 3.22 to create a dendogram with the Unweighted Pair Group with Aritmetic Average (UPGMA) method. Results showed that there were 2 different clusters from the level of similarity in their characteristics. Exotic broilers had 94.65% similarity to male exotic layer chicken and 92.26% to pelung chicken, while Kampung chickens had 90.16% similarity to KUB-1Chicken. In conclusion, it is indicated that the level of similarity of the phenotypic characteristics of pelung chickens were close to the type of exotic broiler and male exotic layer chicken. This level of similarity lead  to the expectation that pelung chickens potential to be a candidate for meat-type of local chicken.
In the Shadows: On Meta-Awareness and Spiraling Effects in Psychotherapy—Comment on Nicole Vigoda Gonzalez and Diana Fosha
Authors: Sass Louis
Published: March 2019

I want to commend Nicole Vigoda Gonzalez (2018) for her sensitive, sophisticated, and successful treatment in the case of Rosa; and I want to commend Diana Fosha (2018) for the development of her phenomenologically sophisticated and effective Accelerated Experiential Dynamic Psychotherapy (AEDP) model, which Vigoda Gonzalez used. In this commentary I focus on a contrast between two different perspectives in Fosha’s model, and implications for the case of Rosa. This contrast includes: (a) AEDP’s focus on descriptive phenomenology, emphasizing the richness of each client’s moment-to-moment, subjective experience, versus (b) Fosha’s seemingly unqualified advocacy, in the Second Avatar version of AEDP, of the therapist explicitly encouraging meta-processing—that is, explicit self-awareness—as a final step of therapeutic healing. In my commentary I suggest that there seem to be certain limiting conditions for such advocacy. Specifically, I discuss how the clinical research literature argues that while meta-processing may be very helpful for some clients, for others—e.g., those employing the distancing defenses of derealization and depersonalization—meta-processing can be psychologically counterproductive. I conclude by re-emphasizing the importance of retaining a descriptive phenomenological perspective in AEDP.
Inflancka Travelogue: 10 Short Essays on “Decalogue”
Authors: Kickasola Joseph G.
Published: March 2019

Kieślowski scholar Joseph G. Kickasola documents his efforts to find and explore the Warsaw apartment complex where Krzysztof Kieślowski filmed his Decalogue series. His startling, unexpectedly emotional experience at such an ordinary place becomes an opportunity to reflect on the films, theorize on the function of place in them, and consider the way that human life and cinema feed into each other. Fictional stories and their cinematic constructions can deepen our experience, and make the world feel more lived in, more true. Nothing magical happened, but everything ordinary happened in all its fullness, like a kind of prophecy, fulfilled.
Non-accidental presence. The reception of Krzysztof Kieślowski in Russia
Authors: Viren Denis
Published: March 2019

Krzysztof Kieślowski is a cult figure among Russian moviegoers, but “proving” this is not as easy as in the case of the popularity of other Polish classic names in Russia, such as Andrzej Wajda and Krzysztof Zanussi. Placing Kieślowski on the list of Polish filmmakers who have influenced Russian culture in this or some other way is a not obvious move. The article is an attempt at exposing the reader to the presence of the director’s films in Russia through the history of the distribution of his films, an analysis of reviews by Russian authors and texts in which Kieślowski’s name appears. It also discusses references to his films in works by other filmmakers. It is complemented by the statements of two Russian directors who talk about the importance of Kieślowski in their work and academic practice.
The profile of M.A. university students – future teachers of English in the process of obtaining full professional qualifications
Authors: Michońska-Stadnik Anna
Published: March 2019

In professional research literature learner identity, motivation and au-tonomy are frequently the focus of attention. Identity is believed to be responsible for beliefs and opinions about the process of language at-tainment. Although much more has been written on learner identity, teacher identity is usually marginalized. The study summarized in this paper focuses on students – future teachers of English (N=32)- who at-tend M.A. EFL seminars to obtain full teaching qualifications. The stu-dents were asked to give answers to seven questionnaire statements referring to their present teaching careers and their former studies. It appeared that students coming from educational backgrounds other than university frequently show gaps in knowledge of second language acquisition theory and practice. What is more, as the ELT seminars ca-ter mostly for students from institutions outside the university, consid-erable remedial work is needed in order to make it possible to pre-pare the students to write their M.A. theses independently.

FOREIGN LANGUAGE ANXIETY IN OUT-OF-CLASS PERFORMANCE.IDENTIFYING LANGUAGE-ANXIETY SOURCES, ITS EFFECTS, AND COPING STRATEGIES
Authors: Morena Katarzyna
Published: March 2019

Language researchers have long been aware that anxiety can be associated with the language learning process and negatively correlate with academic achievement, motivation and successful oral performance. Foreign language anxiety was first defined as a negative feeling associated with a language classroom and resulting from a fear of negative evaluation, tests and communication apprehension (Horwitz and Young, 1991). Some learners also reported that they experienced language anxiety in out-of-class oral performance, that it negatively affected their feeling of competence, and beliefs about their successful language acquisition, and also triggered physiological and cognitive responses. The research aimed at identifying sources of language anxiety and its manifestations in adult EFL learners in out-of-class settings, and a set of six strategies was proposed to help learners mitigate the feeling of foreign language anxiety.

SŁOWA˗WARTOŚCI: INTERKULTUROWOŚĆ UKRYTA W JĘZYKACH
Authors: Dryjańska Agnieszka
Published: March 2019

The present paper attempts to investigate the developement of existential competence within the framework of the intercultural approach to foreign language teaching. The main dimension of this approach to be explored is the application of the semantic analysis of key words for each culture designating values. To better understand the theoretical background of the intercultural competence its main aspects will be analyzed, i.e. alterity, representation, and identity. The analysis will especially include the process of discovering the real meaning of wordswithin their cultural background. Such a reflective approach to teaching and learning foreign languages allows the students to change their ethical attitude towards foreign cultures as well as their own culture.

Authors: Strugielska Ariadna
Published: March 2019

The article demonstrates possible impact of internationalization at Polish universities on the ways in which research interests can be polarized and intercultural competence fostered. Since international educational programs tend to be created by academics whose interest in intercultural competence is secondary, i.e. it derives from the process of internationalization. The perspectives of various research domains are likely to influence concepts of intercultural competence and the ways of its development. Simultaneously, academic interests of lecturers will be polarized by intercultural and international contexts. The said phenomenon is illustrated with examples from an Erasmus+ seminar at the NCU in Poland.
‘What Would Happen If We Were No Longer Able to Narrate?’ Dystopian Speculations and Other Reflections on the Relevance of Narratives for Human Life
Authors: Wolf Werner
Published: March 2019

The contribution highlights the overwhelming importance of narrative for human life. It takes its point of departure from a hypothetically negative assumption: the fiction of an anti-utopian island ‘Udiegesia’, whose inhabitants have lost the ability to narrate. A scenario detailing what would presumably happen in such a case leads on to a (positive) survey of the manifold fields in which narrative is in fact used as a cognitive frame to make sense of, provide orientation in, and a ‘fitness training’ for, life and human societies, a survey which is - in part - inspired by Brian Boyd’s propagation of ‘evocriticism’.2 In the concluding section the claim that all human knowledge is “based on stories”3 will receive brief critical attention. It will be argued that such an exclusive stance is as problematical as the idea that the complexities of narrative’s forms and its various functions for human life can be fully explained by evolutionary theory alone.

Mediumrückwirkung und akustische Strahlungsdämpfung für ein kreisförmiges Plättchen
Authors: Braumann Hans
Published: March 2019

Zur Berechnung des Schallfelds eines kreisförmigen Plättchens, welches kleine harmonische Schwingungen in Richtung seiner Achse ausführt, wird zunächst die akustische Wellengleichung in Bipolarkoordinaten umgeschrieben. Falls das akustische Medium als inkompressibel angesehen werden kann, führt die Wellengleichung auf die Potentialgleichung, welche exakt gelöst wird. Es ergibt sich, daß das Medium so auf das Plättchen zurückwirkt, als wäre dessen Masse um 8R3 ρo/3 erhöht (R Plättchenradius, ρo Dichte des Mediums). Bei kompressiblem Medium kommt zu dieser konserva-tiven Rückwirkung noch die Strahlungsdämpfung hinzu. Für das Zeitmittel der ab-gestrahlten Leistung ergibt sich angenähert 8R6ρo ω4 V2 / π C3 (ω Kreisfrequenz, V Geschwindigkeitsamplitude des Plättchens, c Schallgeschwindigkeit).

Kozłowska, M, Żurek, P, Rodziewicz, E, Góral, K, Żmijewski, P, Lipińska, P, Laskowski, R, Walentukiewicz, AK, Antosiewicz, J, and Ziemann, E. Immunological response and match performance of professional tennis players of different age groups during a competitive season. J Strength Cond Res 35(8): 2255–2262, 2021—We aimed to investigate the effect of physical workloads on immunological response, match performance, and iron metabolism in professional tennis players of different age groups throughout the tournament season and to determine the interdependence of vitamin D status and inflammation. Thirty-eight young, male tennis players with a top national ranking (1–25) participated in this study and were assigned to the following age groups: cadets (CG), juniors (JG), and seniors (SG). Blood samples were collected at the beginning, midpoint, and end of the tournament season to assess the proinflammatory cytokine (tumor necrosis factor—alpha [TNF-α]), anti-inflammatory myokines (interleukin [IL]-6 and IL-10), heat shock proteins (HSP70, HSP27), iron metabolism markers, and vitamin D concentrations. The total number of matches (won and lost) at the national and international events was recorded. The IL-6 and IL-10 concentrations significantly increased across all groups in the middle and end of the tournament season (effect large and very likely). The TNF-α concentration was elevated at the end of the season in CG and SG. The increase in TNF-α concentration corresponded with an increase in hepcidin concentration in these groups. The significant increase in HSP27 concentration was only noticed in SG with normal vitamin D concentrations. In JG and SG, a mild seasonal increase in vitamin D concentration was noted, but still it was insufficient. The immunological response was not affected by the number of tennis matches; however, the anti-inflammatory effect was regulated by higher concentrations of vitamin D. Unexpectedly, most tennis players had vitamin D deficiency. Iron status remained unchanged.
Response Adaptation in Barrel Cortical Neurons Facilitates Stimulus Detection during Rhythmic Whisker Stimulation in Anesthetized Mice
Authors: Barros-Zulaica Natali , Villa Alessandro E. P. , Nuñez Angel
Published: March 2019

Rodents use rhythmic whisker movements at frequencies between 4 and 12 Hz to sense the environment that will be disturbed when the animal touches an object. The aim of this work is to study the response adaptation to rhythmic whisker stimulation trains at 4 Hz in the barrel cortex and the sensitivity of cortical neurons to changes in the timing of the stimulation pattern. Longitudinal arrays of four iridium oxide electrodes were used to obtain single-unit recordings in supragranular, granular, and infragranular neurons in urethane anesthetized mice. The stimulation protocol consisted in a stimulation train of three air puffs (20 ms duration each) in which the time interval between the first and the third stimuli was fixed (500 ms) and the time interval between the first and the second stimuli changed (regular: 250 ms; “accelerando”: 375 ms; or “decelerando” stimulation train: 125 ms interval). Cortical neurons adapted strongly their response to regular stimulation trains. Response adaptation was reduced when accelerando or decelerando stimulation trains were applied. This facilitation of the shifted stimulus was mediated by activation of NMDA receptors because the effect was blocked by AP5. The facilitation was not observed in thalamic nuclei. Facilitation increased during periods of EEG activation induced by systemic application of IGF-I, probably by activation of NMDA receptors, as well. We suggest that response adaptation is the outcome of an intrinsic cortical information processing aimed at contributing to improve the detection of “unexpected” stimuli that disturbed the rhythmic behavior of exploration.
Misconception about Value-added Tax (VAT) Exemption Policy on Animal Feed in the Flour Industry: An Issue on Self-sufficiency of Meat after Reformation
Authors: Raymundus Torganda , Rosdiana Haula , Murwendah Murwendah
Published: March 2019

Flour industry and animal feed industry play an important role in supporting government programs to achieve self-sufficiency of meat. The important role of these animal feed producers has triggered the government to stipulate appropriate tax policies to ensure the growth and development of both industries. Through tax policy instruments, the government has provided facilities in the form of Value Added Tax (VAT) exemption for the delivery of animal feed and animal feed ingredients. However, in its implementation, this policy has not been all-inclusive, leading to a cascading effect suffered by the flour industry. It results in an opportunity cost and cost of taxation affecting the productivity of the flour industry as the producer of animal feed. This study applies a qualitative-descriptive method with data collection techniques of in-depth interview and documentation study. This study explains the implications of VAT exemption policy for the flour industry, evaluates VAT exemption policy on animal feed in the perspective of public policy and productivity of animal feed producers, and analyzes political relations and ideas for VAT policy on animal feed in an effort to support national flour industry and animal feed industry

Authors: SÜKLÜN Harika
Published: March 2019

This study's purpose was to investigate if misconceptions lead to conflicts and increase attention among scholars for further research as well. Although misconception is one of the roots of conflicts is somehow accepted, especially by the practitioners, there are not many empirical studies conducted to investigate if there is a relationship between misconception and conflicts. This study is prepared on a small scale as a starting point. To explore the subject better case study methodology is used.  Two different studies conducted to be able to compare and analyze the situation among the groups.  One group is taken as in-group and the other group is taken as out-group. This study's findings revealed that misconception leads to conflict at workplaces and to a hostile work environment. "We vs. them" situation among the groups and intergroup conflicts are observed. Conclusion and limitation are discussed.

Ayrıca reel kurda meydana gelen gelişmelerin de ticaret dengesi üzerinde önemli etkilere sahip olduğu, bu bağlamda ulusal paranın yabancı para birimlerine karşı uzun dönemde reel olarak değerlenmesinin, ticaret dengesini kötüleştirdiği tespit edilmiştir. Uzun dönem ticaret dengesi ilişkisinden sapmaların yaklaşık %34’ünün bir gözlem dönemi içerisinde ortadan kalktığı gözlenmiştir.
THE EFFECT OF GLOBAL FINANCIAL CRISIS ON SECURITIES PORTFOLIO OF DEPOSIT BANKS: A DIFFERENCE-IN-DIFFERENCES METHOD FOR TURKEY

Published: March 2019

This study analyzes the effects of the global financial crisis of 2008 upon public and private deposit banks’ securities portfolio in Turkey for the quarterly period between 2005 (Q1) and 2015 (Q4). Difference-in-Differences (DiD) method is employed to solve the research question of this paper, which is whether or not there exist a significant change in differences between Turkish public and private banks’ ratio of securities (financial assets) to total assets during and after the crisis. This study concludes by suggesting that after the global financial crisis, securities to assets ratio of publicly owned deposit banks significantly differed from that of privately owned ones in Turkey.Compared to the private deposit banks, there has been a significant decrease in the specified ratio of public deposit banks. This can be explained by taking into account the very nature of public banks. The results of the econometric analyses indicate that after the crisis, unlike the private deposit banks, state-owned deposit banks held fewer securities in their total assets in Turkey, which is in line with the behavior of lending more to eliminate the negative effects of the crisis of 2008.
OTANTİK LİDERLİK VE ÖRGÜTSEL SAPMA DAVRANIŞI ARASINDAKİ İLİŞKİDE ÖRGÜTSEL ÖĞRENME KÜLTÜRÜNÜN ARACILIK ETKİSİ: TÜRKİYE İLAÇ SEKTÖRÜNDE BİR ARAŞTIRMA

Günümüzde örgütler, küreselleşmenin yanı sıra sosyal, politik ve teknolojik alandaki yeniliklerle beraber yoğun bir baskı altına girmektedir. Gelişmekte olan veya az gelişmiş ülkelerde sıkça karşılaşılan bir endişe kaynağı olan örgütsel sapma davranışları da bu duruma eklendiğinde lider konumdaki kişilerin yükü daha da artmaktadır. Bu sebeple de etkili bir liderlik uygulamasının ne şekilde yapılması gerektiği hususu, konu ile ilgili tartışmaların merkezinde yer almaktadır. Otantik liderlik, umut, dayanıklılık, sabır, iyimserlik, refah ve bu tutumların örgütlere uygulanabilirliği gibi olumlu düşüncelere odaklanan popüler liderlik tarzlarından biridir. Örgütsel öğrenme kültürü ise çalışanları standart etik kurallara uymaya ve örgütün çıkarları için çaba sarf etmeye yönlendirmektedir.
Bu çalışmanın temel amacı otantik liderlik ve örgütsel sapma davranışı arasındaki ilişkide örgütsel öğrenme kültürünün aracılık etkisini araştırmaktadır. Bu bağlamda, Türkiye’de İSO 500’de yer alan ilaç sektöründe faaliyet gösteren 6 işletmenin beyaz yakalı çalışanlarından 212 kişiden elde edilen verilerle, örgütsel öğrenme kültürünün otantik liderlik ve örgütsel sapma davranışı arasındaki ilişkide aracı etkisinin olup olmadığı hiyerarşik regresyon analizi ile bulunan aracılık etkisinin anlamlı olup olmadığı Sobel Testi ile belirlenmiştir. Sonuçta, otantik liderliğin örgütsel öğrenme kültürü ile pozitif yönde anlamlı ilişkili olduğu, örgütsel öğrenme kültürünün örgütsel sapma davranışı üzerinde negatif yönde bir etkiye sahip olduğu ve örgütsel öğrenme kültürünün otantik liderlik ve örgütsel sapma davranışı arasındaki ilişkide tam aracılık etkisi olduğu saptanmıştır.

Metamorphism and thermal properties of fresh snow (study in the Moscow region)
Authors: Chernov R. A.
Published: March 2019

As a result of laboratory tests were obtained values of the coefficient thermal conductivity (Keff) of new snow for different types of the solid precipitation: plates, needles, stellars, graupels. Snow samples were collected during a snowfall and placed in the freezer. For all types of sediment thermal conductivity of snow is equal to 0.03–0.04 W/m·°C. Transformation of new snow occurs within 10 days at average temperature −10 °C and the gradient temperature of 50–60 °C/m. Under these conditions, the metamorphism leads to an increase the density of snow, size of grains and rounded snow particles. At the beginning of the experiment, the thermal conductivity of snow is linearly increased in proportion to the density of the snow. However, after 3–5 days Keff stabilized at about 0.08–0.09 W/m·°C, although the density of the snow and size of grains continued to increase. This effect occurs with the appearance of faceted crystals and loosening of snow. In the future, while maintaining a negative temperature coefficient of thermal conductivity remained unchanged. Thus, the temperature gradient metamorphism affect to the thermal conductivity snow, which plays an important role in maintaining the thermal insulation properties of snow cover. The article describes the formula to calculate the thermal conductivity of the snow conditions in the temperature gradient metamorphism. Such conditions are characteristic of the vast expanses of the north and northeast of the European part of Russia. On the basis of long-term observations in Moscow shows the average minimum and maximum values for the density of the snow woods and fields on the basis of which can be calculated for the thermal properties of the snow.

Published: March 2019

Results of distant satellite sounding (the TERRA satellite) of high-mountainous areas and digital models SRTM 4.1 and ASTER DEM G2 of the same relief were used to calculate the following parameters of high-mountain dammed glacial lakes: area, depth, the water volume, excess of the dam above the water level. It is important for estimation of the water volume that can be dangerous for a break-through of a dammed lake. Formulas deduced to calculate the depth and volume of a lake for several sections of its area were tested and proposed. It is demonstrated that the regression equation V = Hmax × F, where Hmax is maximum depth of the lake, can be used as the parameterization of the formula «lake volume V equals the product of the area F on average depth D». More precise values of the coefficients a and b in the formula V = aFb were also obtained. Parameters and the water volumes of lakes were estimated for the river Gunt (right tributary of Pyanj River) basin. According to [28], there are 428 high-mountain lakes in this region with their total area ≥ 2500 m2. For basin Inflow of melted snow and glacier water caused by the rise of mean summer air temperatures in 1931–2015 was estimated for the lake Rivankul basin (the Pamir Mountains).
SEXUALIDAD, CUERPO Y PODER: DEL GOBIERNO DE LA CARNE AL GOBIERNO DE LAS POBLACIONES
Authors: Retana Alvarado Camilo
Published: March 2019

El presente escrito brinda una reflexión surgida en el contexto del último proceso electoral llevado a cabo en Costa Rica, en febrero del 2018. Específicamente, presenta líneas de aná- lisis para abordar la forma en la que la sexualidad se ha convertido en una zona privilegiada de la vida social, cuando de gestionar y controlar los cuerpos de los individuos se trata, así como el comportamiento de las poblaciones que estos conforman. Para ello, se revisan las nociones de cuerpo y sexualidad, su permeabilidad a las prácticas sociales y, por lo tanto, su susceptibilidad a la transformación, la manipulación, la gestión y la dirección, en tanto operan como ejes de gobierno. Luego, se pasa a analizar la sexualidad como espacio de “gubernamentalidad”, relacionada con administraciones localizadas o “micro”, para llegar al reflejo de ello en los debates electorales, centrados de manera unilateral en cuestiones referidas a la sexualidad, dejándose de lado otras más decisivas.
Voluntary wheel running and testosterone replacement increases heart angiogenesis through miR-132 in castrated diabetic rats
Authors: Chodari L , Dariushnejad H , Ghorbanzadeh V
Published: March 2019

Objective

Low levels of testosterone in men with diabetes are associated with cardiovascular complications. We investigated the effect of testosterone and voluntary exercise on heart angiogenesis in castrated diabetic rats.

Methods

Sixty-three diabetic rats were treated with testosterone 2 mg/kg/day or voluntary exercise alone or combination of these two for 6 weeks. At the end of the study, heart tissue samples were collected and used for CD31 detection by immunohistochemical method and determination of miR-132 levels.

Results

miR-132 levels and CD31 of heart tissue were higher after testosterone administration and in the voluntary exercise group in diabetic rats after 6 weeks. Combination of testosterone and voluntary exercise had synergistic effect on angiogenesis and miR-132 level. In castrated diabetic rats, there were significantly lower levels of miR-132 and CD31 in heart tissue compared to the diabetic group, whereas testosterone and exercise reversed these effects. In addition, testosterone supplementation plus exercise had an additive effect on miR-132 levels and CD31 in castrated diabetic rats.

Conclusions

It was concluded that castration in rats leads to reduced miR-132 levels and subsequently decreased angiogenesis in diabetes. Testosterone plus voluntary exercise improved angiogenesis possibly through enhancement of miR-132 levels in heart of castrated diabetic rats.
Lokális szirolimuszterápia sikeres alkalmazása facialis angiofibromák kezelésére Bourneville–Pringle-kórban szenvedő gyermekeken

Abstract:

Facial angiofibroma is the characteristic symptom and also a major diagnostic criterion for Bourneville–Pringle disease. The centrofacially localized hamartomatous tumours start to appear in early childhood, and progress over time. Facial angiofibromas represent a significant cosmetological problem for the patients and a therapeutic challenge for the physician. Beside the traditional invasive treating methods, topical sirolimus is a new, promising and well-tolerated treatment modality. Several studies and case reports have been published on this new therapeutic approach, but recommendation for the optimal sirolimus concentration still does not exist. We report here two cases when children were successfully treated with topical sirolimus. Orv Hetil. 2019; 160(13): 516–520.
