Theorising Practice and Developing Practically Relevant Insights in Organisational Research
Authors: Liubertė Irina
Published: October 2018

In management research, theoretical abstractions, which are traditionally derived based on economic and individualist ontological assumptions, are limited in the ability to produce practically relevant insights and increase the divide between organisational practitioners and scientists. This paper argues that contemporary theory of practice, which jointly considers agency, structure and materiality, overcomes the confrontation and integrates scientific rigour with the richness of organisational practice. The author thereby introduces the origins of practice theory, analyses the definition of practice and explores the areas of management research where practice theory is currently adopted.
Specifics of Management of Enterprise Innovation Activities in the Czech Republic – The Decision-Making Mechanism
Authors: Peterková Jindra , Franek Jiří
Published: October 2018

The majority of Czech managers are aware that the long-term competitiveness of the company depends primarily on the use of innovative technical solutions and investments in new technologies. Despite awareness of the importance of innovation, many companies do not know how to manage, implement, and evaluate them. Empirical research showed that most innovation firms implement, but do not systematically manage the implementation of innovative projects and the allocation of funds. There is a contradiction between companies’ ability to orientate themselves in the approaches available in the area of innovation management and the existence of a large number of approaches that can be used to address a particular type of innovation problem. A set of innovation concepts has been created to solve those challenges. Practical steps of the decision-making mechanism for selecting innovation concepts have been proposed. The decision-making mechanism is based on the analytic hierarchy process (AHP) and serves primarily for managers of medium and large enterprises.

Cost of Mining Coal as an Element of Multi-Criteria Assessment Using the Development Measure – A Case Study
Authors: Sulik-Górecka Aleksandra , Korban Zygmunt
Published: October 2018

The paper presents the possibilities of applying one of the multi-criteria assessment methods (the development measure method) in the processes of multi-variant design of technical and organizational solutions on the example of selecting equipment for a newly designed mine working in a hard coal mine. Using the case study, the authors proposed an alternative solution for decision-making problems in mining companies in relation to solutions based solely on unit costs of coal mining. The case study is preceded by the presentation of general principles regarding cost accounting in mining companies as well as the use of multi-criteria assessments.
The Influence of Chemical Composition of Tough-to-Machine Steels on Grinding Technologies
Authors: Ivanova Tanyana N. , Korshunov Aleksandr I. , Božek Pavol
Published: October 2018

The main purpose of processing of tough-to-machine materials is improving of cutting process of steels with different physicochemical properties and alloying by means of various chemical elements in combination with heat treatment. Producing of high quality surface layers depends on properties of material used to make details, that is why reasons of tough machining were identified: influence of chemical composition and resulting structure. The studies of grinding of tough-to-machine materials were undertaken by means of grinding wheels made from synthetic diamonds as they are most resistant and highly-productive. Based on the studies recommendations for using of characteristics of grinding wheels and tough-to machine steel grades are given.

Research on heat processes during grinding allows us to determine patterns showing how cutting speed, detail motion speed, area and action period of contact influence temperature and speed of heat processes in surface layers as well as depth of heating. These patterns also give the chance to show interrelation between temperature and rate of heating and cooling. This gives an opportunity to predict state of structure of surface layer of details made of tough-to-machine steels under different machining conditions reasonably.
Social Perception of Hard Coal Mining in Perspective of Region’s Sustainable Development
Authors: Bijańska Jolanta , Kuzior Aleksandra , Wodarski Krzysztof
Published: October 2018

This article presents a pilot study on the local community’s social perception regarding coal mines in Upper Silesia. The research was performed in connection with the smog, which was persistent and harmful to residents during the winter months of 2016. The researchers put forward to the local community the following two survey questions: 1. Is the image of coal mines in the eyes of the local community positive or negative? 2. Are coal mines socially responsible and is coal a good energy source? The aim of this article is to indicate the relationship of the local community to the presence of hard coal mines in the neighbourhood and their social role. Also, this work looks to identify the nuisances perceived by the inhabitants of the examined region about mining enterprises and whether these burdens should result in abandonment of hard coal mining. Pilot studies were conducted with the use of a diagnostic survey. The study was carried out in January 2017 on a sample of 267 people, comprising Silesian University of Technology students residing in Upper Silesia. An environmental survey technique was used. The researchers hypothesise that the image of mining and coal as a fuel for the local community is negative and the mines are not socially responsible enterprises. This research shows that the operation of mines is essential for society and its stability as it affects economic, social and energy safety. A large proportion of the respondents defined the image of mining as positive (108 people), but 76 people indicated that the image was rather negative. Most respondents pointed to the benefits of the mine’s operation. Opinions on social responsibility were divided, and most respondents failed to provide concrete examples of social engagement, so the first hypothesis was partly confirmed. Although the respondents pointed to various nuisances resulting from the mining companies operating in their environment, they also recognised significant social aspects related to employability and access to relatively cheap fuel. However, they do not realise the social involvement of mines, which is one of the conditions of sustainable development. Pilot studies allowed for the initial identification of problems and verification of the research tool utilised in this study.
Application of Coordinate Measuring Arm for Accurate Measurement of Child Growth
Authors: Rępalska Marta , Woźniak Adam , Kulus Marek
Published: October 2018

The article describes an approach to measure child growth using a coordinate measuring arm. For this purpose, a test set up has been built to measure the lower leg length directly on the knee surface and with the help of a plate. The use of the plate resulted in the distribution of pressure on the surface to be measured. Based on the results, the LLV (a lower leg growth velocity) was determined and studies were carried out to estimate the uncertainty of this factor. The obtained LLV results at 0.4 mm/week, correspond to the results of studies conducted on specialist test set-ups for knemometric measures described in the literature. The obtained results also allow recognizing periods of good health and bad health of the child.

Evaluation of Tendency to Blackspot Bruising and Enzymatic Discoloration of Potato Tubers
Authors: Hara-Skrzypiec Agnieszka
Published: October 2018

Enzymatic discoloration of potato tubers initiated by mechanical impact bruising and the discoloration which appears after tuber cutting are crucial quality traits of the cultivated potato. The presented determination of blackspot bruise susceptibility includes evaluation of the trait with two impact methods - the rotating drum and the falling bolt. These two methods affect both the physical and the biochemical properties of tubers. Evaluation of the discoloration potential after tuber cutting (ED) is also discussed. Evaluating the discoloration potential of tubers is one of the most important points in determining potato quality.
Assessment of Phytotoxic Potential of Potato Genotypes
Authors: Sołtys-Kalina Dorota
Published: October 2018

In the laboratory studies on allelopathy, phytotoxicity is defined as a negative impact of plant’s extracts or natural compounds derived from plants, on germination and/or growth of the tested (acceptor) plant. Glycoalkaloids are the main biologically active compounds of the potato and are involved in potato phytotoxicity (the correlation coefficient of the length of the test plant with the concentration of total glycoalkaloids present in the leaf extracts of forty potato genotypes was r = -0.41). The assessment of phytotoxic abilities of the potato is a two-step procedure which consists of determining glycoalkaloids in potato leaf extracts and analyzing the root and hypocotyl lengths of the test plant growing in potato leaf extracts.

Evaluation of Potato Cultivars and Breeding Lines for Resistance to Globodera Rostochiensis and Globodera Pallida
Authors: Przetakiewicz Anna , Milczarek Dorota
Published: October 2018

Nematodes are among the most important agents affecting potato crops. Heavy infestations by Globodera rostochiensis and G. pallida can cause significant yield losses and limit the choice of potato cultivars that can be grown effectively (Oerke, 2006). Breeding of new potato cultivar resistant to G. rostochiensis and G. pallida is a long-term process. It is preceded by screening of potato breeding lines for resistance in repeated biotests, which seems to be the most effective and safest method of protection. Evaluation of nematode resistance is an important element of characterization of breeding lines and new cultivars. Resistance to Globodera spp. is evaluated in biological tests. The use of DNA markers for detecting nematode resistance genes may be an alternative approach to phenotypic evaluation of resistance degree of potato plants (Jena and Mackill, 2008). The goal of this report is focused on a description of resistance assessment procedure of breeding lines and varieties of potato to PCN and on comparison of biological and molecular methods of resistance evaluation. Presented information is addressed to both breeders and Polish inspection services.
Laboratory Assessment of Potato Resistance to Phytophthora Infestans
Authors: Brylińska Marta , Śliwka Jadwiga
Published: October 2018

Resistance breeding is a very important alternative to chemical control of late blight. Many resistance (R) genes from the wild Solanum species have been discovered and introduced into the cultivated potato. The laboratory methods to assess the resistance to late blight such as tests on detached leaflets, leaves, tuber slices, or whole tubers, are easy, cheap, fast and provide a good estimation of resistance that can be further confirmed in field trials for the selected material. Laboratory assessment is particularly useful for materials, in which major resistance genes segregate and the resistance is qualitative rather than quantitative.
Field Evaluation of Potato Resistance Against Phytophthora Infestans under Natural Infection Pressure
Authors: Plich Jarosław , Tatarowska Beata
Published: October 2018

Although development of potato cultivars resistant to late blight has long been one of the primary goals of potato breeding programs, several different methods of field resistance evaluation have been used by potato breeders. Recently, within the EucaBlight network (www.euroblight.net), common methods of late blight evaluation have been agreed on, and these methods are currently highly recommended for use by all those interested in evaluating the resistance of the potato to late blight. Here, we describe a method of evaluating potato resistance in field conditions routinely used at Młochów Research Center, which is compliant with recommendations of the EucaBlight protocol.
Sampling, Maintenance and Pathotype Identification of Synchytrium Endobioticum (Schilb.) Perc
Authors: Przetakiewicz Jarosław
Published: October 2018

Plant Breeding and Acclimatization Institute - National Research Institute (IHAR-PIB) is responsible for pathotype identification of Synchytrium endobioticum isolates collecting from Poland. Pathogenicity tests are carried out using the Glynne-Lemmerzahl method, according to EPPO Standard PM 7/28. Pathotypes are defined based on their reaction to a range of well-characterized differential cultivars of potato. Assessment of one isolate of the fungus requires more than 20 differential cultivars. All pathotypes of S. endobioticum from Polish reference collection are multiplied and maintained (fresh warts) on tubers of extremely susceptible cultivars continuously. For all references pathotypes and isolates of S. endobioticum, the compost with winter sporangia are prepared for long-term of maintenance.
Assessment of Potato Resistance to Synchytrium Endobioticum
Authors: Przetakiewicz Jarosław , Plich Jarosław
Published: October 2018

In Poland the Plant Breeding and Acclimatization Institute - National Research Institute (IHAR-PIB) is responsible for officially assessing the resistance of potato breeding lines and cultivars to Synchytrium endobioticum. In the official assessment of wart resistance the modified Glynne-Lemmerzahl method is used. A full cycle of assessment of the wart disease resistance requires 42 - 45 tubers per cultivar/breeding line. Forty two tubers are used in laboratory tests. To complete the laboratory tests, another 10 tubers are inoculated with winter sporangia of the fungus, using ring test. The final results are available after 3 years of investigation. If necessary, the full cycle of resistance tests to S. endobioticum can be performed during one year on 15 tubers in each of the 3 replications (45 tubers in total). Molecular verification of potato genotypes resistance to pathotype 1(D1) is possible with the use of SCAR marker Nl25-1400. Nevertheless, an official phenotypical assessment of advanced breeding lines, as the final verification of their resistance, is required.
Selection of Potato Parental Lines with Complex Resistances to Potato Pathogens and Pests
Authors: Flis Bogdan
Published: October 2018

The efficiency of breeding new potato cultivars may be increased by pre-breeding that is by developing parental lines, which have new traits, not present in the genetic pool available for breeders or have new combinations of genes, or have improved level of economically important traits. The use of parental lines in commercial breeding programs is expected to ensure the biological progress in the newly created cultivars of potato. At the beginning, the development of parental lines in Młochów Research Center of Plant Breeding and Acclimatization Institute - National Research Institute (IHAR-PIB) was focused on resistance to viruses and later on resistance to late blight and other pathogens. The procedures of selecting resistant parental lines are described. These procedures were initially based on purely phenotypic tests for resistance, which lately were supplemented with marker assisted selection (MAS) applying molecular markers linked with some resistance genes.
Evaluation of the Length of the Vegetation Period of the Potato
Authors: Plich Jarosław
Published: October 2018

Potato cultivars are classified into maturity groups according to the length of the vegetation period required to produce a harvestable product. Although accurate classification of potato cultivars to a specific maturity group is of great practical importance, there is no standard method to characterize the maturity type of potato cultivars. In this work, the method of evaluation of vegetation period routinely used at IHAR-PIB, Młochów Research Center is described.
Effects of initial concentration and irradiation dose to degradation of di butyl phthalate from phosphoric acid (30 % P2O5)
Authors: Bounemia Louisa , Mellah Abdelhamid
Published: October 2018

The pretreatment of the phosphoric acid is a stage of utmost importance leading to an optimal recovery of the uranium present in this acid. To this end, the degradation of the organic matter which obstructs considerably this recovery was tested by γ irradiation. This study lies within the scope of the radiation/matter interaction; concerning the use of the γ irradiator as proceed of phosphoric acid purification by the degradation of di butyl phthalate (DBP). Studies of the interaction of γ radiation with phosphoric acid solutions polluted by an organic matter concern the study of the influence of some parameters such as: dose rate (0.5–35 kGy), initial concentration (50–500 mg/L) of the pollutant, pH and % in P2O5 on the degradation of organic matter by γ irradiation. The reactions followed pseudo first order kinetics for different initial concentrations. The results made it possible to say that the degradation of di butyl phthalate by γ irradiation is dependent on the amount of the concentration of DBP and pH. The G-values decreased with absorbed doses, and increased with higher initial concentrations.Purification of phosphoric acid by γ radiation does not degrade the quality of this acid.
Colonial Violence and the Roots of Fascist Writing
Authors: Santiáñez Nil
Published: October 2018

This article explores the connection between fascist writing and modern colonialism through the analysis of several works produced by F.T. Marinetti, Rafael Sánchez Mazas, and Ernst Jünger. Each of them visited Africa at some point in their lives. Marinetti spent fall 1911 in Libya, where he reported on the Turco-Italian War; his chronicles were collected in La Bataille de Tripoli (1912). Sánchez Mazas was sent to Morocco in fall 1921 as the war correspondent for El pueblo vasco, a daily that published his series of articles - “La campaña de África” - on the Rif War. Jünger went to Algeria in 1913 to receive training as a new member of the French Foreign Legion, an episode that he would novelize in Afrikanische Spiele (1936). This study contends that the stay of these three writers in Africa was an event that, together with other factors, determined their fascism.
The Evaluation of the Effects of N-Acetylcysteine on Cisplatin-Induced Alterations in Exploratory Activity in Elevated Plus Maze Test in Rats
Authors: Pantic Milica , Minic Milos
Published: October 2018

The aim of this study was to evaluate the potential beneficial effect of N-acetylcysteine (NAC) on cisplatin-induced alterations in anxiety levels in rats, by means of parameters of the exploratory activity obtained in the elevated plus maze (EPM) test. Animals were divided into four groups: control group, cisplatin group (7.5 mg/kg/weekly of cisplatin), N-acetylcysteine group (500 mg/kg/weekly of NAC), and cisplatin plus N-acetylcysteine group (7.5 mg/kg/weekly of cisplatin, and 500 mg/kg/weekly of NAC). After two weeks of treatment, exploratory activity (estimated by means of the number of rearings, head-dippings and the number of total exploratory activity episodes) was significantly reduced in cisplatin group comparing to control values. Although NAC induced no alterations in exploratory activity when applied alone, simultaneous administration with cisplatin resulted in significant attenuation of cisplatin-induced decline in exploratory activity. The exploratory activity gradually decreased in time-dependent manner during five minutes of EPM test in all groups. The results of this study confirmed clear beneficial effect of NAC supplementation against cisplatin- induced neurotoxicity in rats. Antioxidative properties of NAC were manifested through restoration of exploratory activity, confirming that NAC administration can attenuate anxiogenic effect of cisplatin therapy. Those results could recommend NAC supplementation as a potential protection against cisplatin-induced neurotoxicity.
Hitler – das „Heilige in Erscheinung“?
Authors: Heep Stefan
Published: October 2018

Die religiöse Dimension des Nationalsozialismus ist Gegenstand einer sehr kontroversen Fachdebatte, die von der Ablehnung einer solchen über Begriffe wie Religionsersatz, Ersatzreligion und politische Religion bis hin zu „echter“ Religion reicht. Ansatz dieses Artikels ist, dass viele Hitler als das „Heilige“ im Sinne Rudolf Ottos erlebten. Um das zu verstehen, wird der Glaube Hitlers in Relation gesetzt zum Glauben an Hitler, und die damals populäre Ansicht, der Nationalsozialismus sei das „wahre“ Christentum, wird Hitlers Absicht gegenübergestellt, ein „Deutschtum“ nach dem Vorbild des Judentums zu schaffen. Es entstand ein religiöser Glaube, der maßgeblich von der Wirkung Hitlers gespeist wurde. Nur weil Hitler über Jahrhunderte tradierte Wahrnehmungsmuster bediente, konnte das areligiöse Fusionserlebnis, das seine Reden hervorriefen, als das „Heilige“ interpretiert werden.
Das Dogma der Unübersetzbarkeit des Korans – eine kritische Rekonstruktion
Authors: Selmani Lirim
Published: October 2018

Der Beitrag thematisiert die Genese des Dogmas der Unübersetzbarkeit des Korans. Mit Unübersetzbarkeit ist gemeint, dass der Koran nichtübersetztwerdenkann, nicht, dass er nichtübersetztwerdensoll. Das Dogma besagt, dass die sprachliche Form des Korans göttlich gewollt ist und auf eine himmlische arabische Urschrift zurückgeht, so dass der Koran unübersetzbar ist. Hier ist der Frage nachzugehen, welche Faktoren die Entwicklung dieses Dogmas begünstigt haben. Einen zweiten Schwerpunkt bildet der Vergleich islamischer und islamwissenschaftlicher deutscher Koranübersetzungen. Religionswissenschaftlich ist dies von Interesse, weil so veranschaulicht werden kann, wie sich Gläubige und Wissenschaftler zum selben Gegenstand verhalten, wie sie ihre voneinander abweichenden Haltungen begründen und legitimieren. Es wird die These vertreten, dass der Koran übersetzbar ist. In Übersetzungen geht allerdings vieles vom Originaltext verloren, was aber für alle übersetzten Texte gilt.

Published: October 2018

We report the synthesis of functionalized 1,3-bis(diphosphacyclobutadiene) complexes via the insertion of carbon-oxygen bonds of ethers, esters, aldehydes and amides into the P–Si bond of silylated complexes. Reactions of [K(tol)2][Co(η4-P2C2R2)2] [[K(tol)2][1a]:R=tBu,[K(tol)2][1b]:R=tPent (=tert-pentyl)] with Me3SiCl afford the trimethylsilyl-substituted derivatives [Co(η4-P2C2R2SiMe3)(η4-P2C2R2)] (2a,b, R=tBu,tPent). The Me3Si group is connected to a phosphorus atom of one of the 1,3-diphosphacyclobutadiene ligands.2a,breadily react with organic substrates containing C–O single and C=O double bonds at ambient temperature. [Co(η4-P2C2R2(CH2)4OSiMe3)(η4-P2C2R2)] (3a,b) are formed by reaction of2a,bwith traces of THF. They can also be isolated by reacting the THF solvates [K(thf)2{Co(P2C2tBu2)2}] ([K(thf)2][1a]) and [K(thf)3{Co(P2C2tPent2)2}] ([K(thf)3][1b]) with Me3SiCl in toluene or THF. The adamantyl-substituted complex [Co(η4-P2C2Ad2(CH2)4OSiMe3)(η4-P2C2Ad2)] (3c) was prepared analogously from [K(thf)4{Co(P2C2Ad2)2}] and Me3SiCl.[K(thf)2][1a]reacts cleanly with Ph3SnCl affording [Co(η4-P2C2tBu2SnPh3)(η4-P2C2tBu2)] (4) in high yield. Reaction of2awith styrene oxide affords [Co(η4-P2C2tBu2PhC2H3OSiMe3)(η4-P2C2tBu2)] (5) as a single regioisomer. By contrast, multinuclear NMR spectroscopic studies indicate mixtures of two isomeric insertion products6/6′ and7/7′, respectively, which result from the insertion of 1,2-epoxy-2-methylpropane and 1,2-epoxyoctane. Moreover, these monitoring studies show that reactions of2awith acyclic ethers afford alkyl substituted complexes such as [Co(η4-P2C2tBu2Et)(η4-P2C2tBu2)] (8) and alkylsilyl ethers. Reaction of2awithγ-butyrolactone gives [Co(η4-P2C2tBu2(CH2)3C(O)OSiMe3)(η4-P2C2tBu2)] (9) via cleavage of the endocyclic C–O single bond of the lactone. Benzaldehyde and acetone cleanly react with2ato [Co(η4-P2C2tBu2CH(Ph)OSiMe3)(η4-P2C2tBu2)] (10) and [Co(η4-P2C2tBu2CMe2OSiMe3)(η4-P2C2tBu2)] (11), while the sterically more demanding ketones 3-pentanone and acetophenone selectively yield the known hydride complex [Co(η4-P2C2tBu2)2H] (A). Phenyl isocyanate reacts with2aat elevated temperature to form [Co(η3-P2C2tBu2CON(Ph)SiMe3)(η4-P2C2tBu2)] (12) with a functionalizedη3-coordinated ligand.[K(tol)2][1a],[K(tol)2][1b],2a,2b,3a–c,4,5, and9–12were isolated and characterized by multinuclear NMR spectroscopy, UV/Vis spectroscopy and elemental analysis.[K(tol)2][1b],2a,2b,3c,4,5, and9–12were additionally characterized by X-ray crystallography.
“I Don't Need PrEP Right Now”: A Qualitative Exploration of the Barriers to PrEP Care Engagement Through the Application of the Health Belief Model
Authors: Felsher Marisa , Szep Zsofia , Krakower Douglas , Martinez-Donate Ana , Tran Nguyen , Roth Alexis M.
Published: October 2018

The Health Belief Model has been useful for studying uptake of HIV prevention behaviors and has had limited application to understanding utilization of pre-exposure prophylaxis (PrEP), a biomedical strategy to reduce HIV acquisition. We recruited 90 persons undergoing HIV screening and educated them about PrEP. We followed up with 35 participants approximately 3 weeks later and quantitatively assessed PrEP uptake. No participant had initiated PrEP. We conducted in-depth interviews with 15 participants to explore situational factors impacting this decision. In this paper we provide an overview of PrEP-related engagement using qualitative data to contextualize (in)action. While participants perceived PrEP as beneficial, perceived benefits did not outweigh real- and perceived barriers, such as financial and time-related constraints. In order to promote PrEP uptake, cues to action that increase the benefits of PrEP during seasons of risk, and interventions that reduce real and perceived barriers are needed.
Perspectives on Factors Related to HIV Risk and Preventative Interventions at Multiple Levels: A Study of African Immigrant Women Survivors of Cumulative Trauma
Authors: Sabri Bushra
Published: October 2018

African immigrant women survivors of cumulative trauma are at high risk for HIV infection. This study aims to identify survivors' perceptions of (a) contextual (i.e., community, and relationship) and individual-level risk and protective factors for HIV among African immigrant women in the United States and (b) areas and strategies of HIV prevention intervention at contextual and individual levels. Qualitative data for this study were collected from African-born women (n = 39) in Maryland, Virginia, and Washington, DC, from February 2017 to March 2018. Seventeen in-depth interviews and five focus groups were conducted with African immigrant survivors of cumulative trauma. Results revealed HIV prevention intervention needs and risk and protective factors for HIV at the community (e.g., community education), relationship (e.g., intimate partner violence, family), and individual (e.g., women's empowerment) levels. These findings can inform the development of culturally tailored multilevel HIV prevention interventions for African immigrant women.

Deciphering Hybrid Larch Reaction Norms Using Random Regression
Authors: Marchal Alexandre , Schlichting Carl D , Gobin Rémy , Balandier Philippe , Millier Frédéric , Muñoz Facundo , Pâques Luc E , Sánchez Leopoldo
Published: October 2018

The link between phenotypic plasticity and heterosis is a broad fundamental question, with stakes in breeding. We report a case-study evaluating temporal series of wood ring traits of hybrid larch (Larix decidua × L. kaempferi and reciprocal) in relation to soil water availability. Growth rings record the tree plastic responses to past environmental conditions, and we used random regressions to estimate the reaction norms of ring width and wood density with respect to water availability. We investigated the role of phenotypic plasticity on the construction of hybrid larch heterosis and on the expression of its quantitative genetic parameters. The data came from an intra-/interspecific diallel mating design between both parental species. Progenies were grown in two environmentally contrasted sites, in France. Ring width plasticity with respect to water availability was confirmed, as all three taxa produced narrower rings under the lowest water availability. Hybrid larch appeared to be the most plastic taxon as its superiority over its parental species increased with increasing water availability. Despite the low heritabilities of the investigated traits, we found that the expression of a reliable negative correlation between them was conditional to the water availability environment. Finally, by means of a complementary simulation, we demonstrated that random regression can be applied to model the reaction norms of non-repeated records of phenotypic plasticity bound by a family structure. Random regression is a powerful tool for the modeling of reaction norms in various contexts, especially perennial species.
Income Disparities and Cardiovascular Risk Factors Among Adolescents
Authors: Jackson Sandra L. , Yang Emily C. , Zhang Zefeng
Published: October 2018

BACKGROUND AND OBJECTIVES:

Socioeconomic disparities in cardiovascular health among adults have been documented, but disparities during adolescence are less understood. In this study, we examined secular trends in 7 cardiovascular risk factors and disparities among US adolescents.

METHODS:

We analyzed NHANES data from 1999 to 2014, including 11 557 (4854 fasting) participants aged 12 to 19 years. To examine trends in cardiovascular risk factors, adolescents were stratified into 3 groups on the basis of family poverty-income ratio: low income (poverty-income ratio, <1.3), middle income (≥1.3 and <3.5), and high income (≥3.5).

RESULTS:

From 1999 to 2014, the prevalence of obesity increased (16.5%–21.0%, P = .001) but only among low- and middle-income adolescents, with significant disparities in prevalence by income (21.7% vs 14.6% among low- versus high-income adolescents, respectively, in 2011–2014). In addition, there were significant and persistent disparities in the prevalence of smoking (20.8% vs 7.4% among low- versus high-income adolescents, respectively, in 2011–2014), low-quality diet (67.8% vs 49.0%), and physical inactivity (25.6% vs 17.0%). No significant disparities were observed in the prevalence of prediabetes and diabetes, hypertension, or hypercholesterolemia, although the prevalence of prediabetes and diabetes increased among low-income adolescents (21.4%–28.0%, P = .01). Overall, the prevalence of adolescents with 2 or more risk factors declined (48.3% to 37.1%, P<.001), but this decline was only significant for high- and middle-income adolescents.

CONCLUSIONS:

Recent improvements in cardiovascular health have not been equally shared by US adolescents of varying socioeconomic status.

El síndrome pospoliomielitis se reconoce como un trastorno neurológico que aparece décadas después de un episodio agudo de poliomielitis y disminuye la capacidad funcional hasta afectar las actividades cotidianas. El evento ocurre en un 20-80% de las personas que fueron afectadas por el virus de la poliomielitis, es más frecuente en las mujeres y existe una relación directa entre el riesgo de padecer este síndrome y el grado de severidad de las secuelas de la polio. El objetivo de este artículo es la presentación de dos casos clínicos de pacientes que presentaron este síndrome después de cerca de cuarenta años de haber presentado un episodio de poliomielitis.  Se cuestiona el concepto de la poliomielitis como una enfermedad estática; además, en los casos presentados esta patología constituye un proceso de difícil diagnóstico y manejo. El impacto psicológico y funcional en los pacientes se asume como un reto para el profesional de salud, puesto que se deben identificar las necesidades clínicas y reducir las barreras asistenciales existentes en la actualidad.

Introducción. Una fístula coronaria se define como la comunicación entre una arteria coronaria y una cámara cardiaca o cualquier segmento de la circulación sistémica o pulmonar. Su incidencia en series angiográficas y población general es muy baja y, en general, cursan de modo asintomático, aunque en raras ocasiones presentan significancia hemodinámica. Su localización en cavidades izquierdas es menos frecuente. Presentación del caso. Paciente masculino de 52 años quien presenta angina de esfuerzo, por lo que fue estratificado de modo invasivo encontrándose una fístula coronaria de la arteria descendente anterior al ventrículo izquierdo. Ante dichos hallazgos, le fue solicitada resonancia magnética nuclear cardiaca como estudio complementario para determinar conducta terapéutica a futuro; sin embargo, el paciente no asistió a controles, ni se le realizó dicho examen. Discusión. Las fístulas coronarias que causan enfermedad arterial coronaria son raras y el drenaje de una fístula coronaria a ventrículo izquierdo es aún más infrecuente. La importancia fisiopatológica de una fístula coronaria está relacionada con el volumen de sangre que fluye y el gradiente de presión a través de la comunicación. La mayoría de fístulas coronarias son diagnosticadas incidentalmente en un cateterismo cardíaco; sin embargo, algunas de estas presentan significancia clínica, siendo sintomáticas y causando complicaciones, por lo que requieren tratamiento a corto plazo. Conclusiones. En algunos casos, las pruebas complementarias iniciales en pacientes con clínica de isquemia miocárdica, realizadas de modo no invasivo, permiten sospechar la presencia de fístulas coronarias. La angiografía coronaria continúa siendo la prueba de mayor precisión diagnostica. Además, se deben tener en cuenta las características anatómicas y fisiológicas para definir si requieren manejo y si este se hará por vía percutánea o quirúrgica.

The Band-e Narges deposit is located about 70 km northeast of the city of Badrud, northern Isfahan province. Band-E Narges ore deposit is mining for magnetite. To release valuable minerals, crushing and grinding implemented for separation ore from the gangue. Magnetic separation and flotation methods for upgrading magnetite iron ore were carried out in different experimental conditions with varied parameters. The particle size of the initial content was 74 microns for flotation, and 150 microns for magnetic separation. The initial samples, with the iron grade of 43.4% and sulfur of 1.9%, are individually subjected to upgrading by floatation and magnetic separation during which the affecting parameters for each method were optimized. The improvement in the optimal condition for magnetic separation culminated in 60.85% for the iron grade, 85.21% iron for recovery and 1.08% for sulfur content. The upgrading by floatation in the optimal mode produced 60.02% iron grade, 80.41% iron recovery and 0.95% sulfur content. To determine the best method for the pre-concentration stage of ore, the content gained from each technique passed reclining for grad improvement. The final content obtained from the magnetic separation of was undergone the floatation test yielded to a content with 64.3% iron grade, 77.15% iron recovery and 0.7% sulfur content. The use of magnetic separation as a pre-concentration stage for floatation method is proposed as an economical method for improving the grade of the iron and reduce the sulfur content and to avoid the high cost of grinding, which is costly part of processing procedures.

Em 2017, comemora-se o centenário da exibição da primeira animação brasileira. O artigo analisa o momento em que a representação feminina tem início nestas animações e seus desdobramentos até hoje. Após uma revisão de literatura, observa-se que, em geral, as personagens nacionais têm se distanciado dos estereótipos de gênero, sendo “Mônica” uma de suas mais conhecidas. Este fato acompanha a mudança do cenário da representação do feminino na animação mundial.
Cinema noir clássico e contemporâneo: influências e construção do imaginário para o gênero
Authors: Augusti Alexandre Rossato , Da Silva Nathalia Lopes
Published: October 2018

O presente trabalho busca investigar como o filme noir clássico influencia o cinema contemporâneo reconhecido como neonoir, e descobrir como essas produções podem estabelecer imaginários sobre a temática do crime. Para tanto, observamos mais detalhadamente os filmes Pacto Sinistro (Strangers on a train), de Alfred Hitchcock, (1951) e Cães de Aluguel (Reservoir Dogs), de Quentin Tarantino (1992). Utilizamos autores como Borde e Chaumeton (1958), Mascarello (2006), Fontes (2011), Silva (2006), Maffesoli (2001) e Metz (2012), com destaque para Rose (2002) no que se refere especificamente à aplicação metodológica, baseada em seu método. Dentre as principais conclusões, evidenciamos que os elementos do noir clássico aparecem nos filmes noir atuais como uma releitura, com diferentes significados.

Introdução: A fonoforese baseia-se na utilização do ultrassom para provocar perturbação dos tecidos, gerando assim, um movimento rápido das partículas, facilitando a absorção do fármaco.Objetivo: Estudar a liberação in vitro da hidrocortisona frente à aplicação de fonoforese, nos modos contínuo e pulsado, a fim de avaliar a real eficácia do seu emprego terapêutico.Materiais e Métodos: Para a realização do estudo foi utilizada hidrocortisona em gel, manipulada em farmácia magistral. Foram feitas análises com a membrana de acetato de celulose associado a hidrocortisona com e sem a aplicação da fonoforese, utilizando ultrassom no modo contínuo e pulsado nos tempos de 0, 5, 10, 15 e 20 minutos de aplicação. As análises foram realizadas em triplicata.Resultados: Os resultados sugerem uma maior liberação da hidrocortisona quando associada à onda sônica terapêutica. Foi constatado, também, que o ultrassom no modo contínuo é mais efetivo quando comparado com o modo pulsado a partir de 5 minutos de aplicação. Nos tempos de 10, 15 e 20 minutos o ultrassom ajustado no modo contínuo se mostrou mais efetivo no que diz respeito à liberação do fármaco quando comparado com o modo pulsado, com aumento de 585, 302 e 260% respectivamente.Conclusão: O ultrassom no modo contínuo é mais efetivo quando comparado com o modo pulsado a 5%, a partir de 5 minutos de aplicação, para liberação e permeação da hidrocortisona 1% em sistema de difusão vertical.

Objetivo: Investigar as relações entre o período de estudo (integral ou parcial) e questões de saúde relacionadas ao sono, comportamento alimentar, status de peso e a prática de atividades físicas em crianças.Materiais e Métodos: Trata-se de um estudo exploratório de corte transversal, no qual participaram 61 crianças de seis a 10 anos de uma escola particular de Florianópolis-SC. Foram investigadas variáveis de sono por meio do Children’s Sleep Habits Questionnaire (CSHQ), comportamento alimentar e prática de atividade física por meio do Questionário de Dia Típico de Atividade Física e Alimentação (DAFA) e status de peso.Resultados: As crianças do período integral apresentaram mediana superior na pontuação do CSHQ, indicando mais problemas com o sono (p=0,014). Além disso, na análise fatorial do CSHQ, o fator mais importante no grupo de crianças do período integral foi formado pelas subescalas “duração do sono” e “parassonias”. Já no período parcial, o fator mais importante foi composto pelos “despertares noturnos” e “parassonias”. Apesar disso, as crianças do período integral praticavam mais atividade física (p=0,036). Não foram observadas diferenças no consumo de alimentos e status de peso entre os períodos (p>0,05).Conclusão: As crianças do período integral apresentaram maior frequência de problemas com o sono e maior prática de atividade física que as crianças do período parcial. Assim, os dados sustentam a hipótese que o período de estudo pode influenciar na saúde das crianças, no entanto, a influência deste fator foi diferenciada de acordo com a variável investigada indicando a necessidade de avaliações, intervenções e acompanhamentos específicos para esta população.
