Le phénomène d’adoption d’une innovation managériale au prisme de la représentation sociale des dirigeants
Authors: Mattelin Pierrard Caroline , Dubouloz Sandra
Published: December 2019

L’objectif de cette recherche est de déterminer les influences que peuvent avoir les dirigeants dans l’adoption d’une innovation managériale et plus particulièrement de comprendre et d’examiner le rôle de leur représentation sociale de l’entreprise libérée dans leur décision d’adopter une telle innovation managériale. Dans cette perspective, nous empruntons une approche cognitive de la stratégie qui suggère qu’au-delà des caractéristiques des dirigeants, une des clefs du processus stratégique réside dans leurs perceptions et représentations sociales. Cette recherche mobilise une étude qualitative exploratoire à travers six entretiens de dirigeants d’entreprises identifiées comme libérées ou en voie de libération. Deux principales contributions sont relevées au terme de ce travail. Tout d’abord, nous montrons que les représentations sociales des dirigeants peuvent être considérées comme des antécédents à l’adoption d’une innovation managériale alors qu’elles n’ont, à notre connaissance, jamais été investiguées en tant que telles. Ensuite, cette approche par les représentations sociales des dirigeants participe à questionner les fondements théoriques de l’entreprise libérée.

Carpal Tunnel Syndrome Due To Tophaceous Gout
Authors: Rich John T , Bush David C , Lincoski Chris J , Harrington Thomas M
Published: December 2019

abstract

Tophaceous gout is a recognized cause of carpal tunnel syndrome. Of 2649 carpal tunnel releases, 15 hands in 13 patients were identified with tophaceous gout in the carpal tunnel. The incidence of tophaceous gout in the carpal tunnel was 0.6%. Twelve of 13 patients were male, and 8 of 10 patients with a history of gout developed carpal tunnel syndrome despite adequate medical treatment. Thus, consideration should be given for tophi as a cause of carpal tunnel syndrome, especially in older men despite medical treatment for gout.

Cervicobrachialgia and Pancoast Tumor: Value of Standard Anteroposterior Cervical Radiographs in Early Diagnosis
Authors: Villas C , Collía A , Aquerreta J D , Aristu J , Torre W , de Rada P Díaz , Gocci S
Published: December 2019

abstract

Ten patients diagnosed with Pancoast tumor were studied retrospectively. The definitive diagnosis was made between 2 and 24 months after the onset of pain. Pain localization was hard to pinpoint; some patients reported pain in four different sites (neck, shoulder, arm, and scapula). Five patients had previously been diagnosed with degenerative, inflammatory, or infectious diseases of the cervical spine or shoulder. In the remaining five patients, the diagnosis was made during the first clinical visit. In three patients, an orthopedic surgeon made the diagnosis by viewing a standard anteroposterior (AP) cervical radiograph. The radiographic evidence arousing suspicion of a Pancoast tumor was the lack of pulmonary air at the top of the affected lung. Furthermore, a parallel study was conducted on 100 consecutive patients seeking treatment for neck pain. By examining the AP radiographs of their cervical spines, the third rib and the top of both lungs were observed in all cases. This study stresses the value of standard AP cervical radiographs in the diagnosis of Pancoast tumor.

EXPERIMENTAL ANALYSIS OF DIFFERENT INSULATED FAÇADE TECHNOLOGIES IN SUMMER CONDITION
Authors: Salvalai Graziano , Sesana Marta Maria
Published: December 2019

At the present, the ventilated façade is one of the most widely used and most innovative systems characterized by different energy saving features, but due to its complexity, the real performances are difficult to predict by numerical analysis. This work shows the results of the monitoring campaign conducted on two Cross Laminated Timber (CLT) test boxes equipped with different thermal coat technologies to realize the performances comparisons. In particular, the investigation focus on the evaluation of surface temperatures of the different wall layers and the indoor air temperature for: i) a micro ventilated façade and ii) two different ETICS solutions. The monitoring campaign has been conducted during the summer season on walls with equivalent thermal transmittance (U-value) and different thermal capacity. In detail, the experimental work has been performed to estimate the Isotec® wall micro ventilated façade performance in comparison with two traditional ETICS technology: the first one realized with EPS and the second one with high density rock wool insulation. The results show that due to the shading effect provided by the external layer, the temperature within the cavity of the ventilate façade is reduced by 8–10 °C, reducing the cooling loads through the wall by 30–40% with respect to ETICS with EPS. The shading and the ventilation effects balance the presence of thermal insulation with less heat capacity; consequently, it validates the good quality of Isotec® as wall technology with performances comparable to ETICS solution with high density rock wool insulation.
Introduction
Authors: Brambilla Chiara
Published: December 2019

The Guest Session makes a contribution to advance conceptual and applied research on borders by paving the way for a more continued dialogue between the emerging interdisciplinary field of critical border studies and anthropology. Specifically, this collection of articles sets out to do two things. On the one hand, to explore the potential of anthropological knowledge, methods, and practice for advancing research on borders and the border-migration nexus. On the other hand, to reflect on how borders are a stimulating research topic to push anthropological theoretical and empirical research forward. Far from being marginal in anthropological knowledge, borders should be regarded as a prominent “laboratory” where anthropologists can search and find appropriate analytical tools to respond to major challenges of the contemporary world. Or, taking up Fabietti’s (1997) pioneering argument, developing an “ethnography of borders” actually means developing an “ethnography of the contemporary”.
Borders of Wealth and Poverty: Ideas Stimulated by Comparing the Mediterranean and U.S.-Mexico Borders
Authors: Heyman Josiah , Ribas-Mateos Natalia
Published: December 2019

How can anthropologists and sociologists share ideas and knowledge on the Mediterranean and U.S.-Mexico borders to deepen insight and understanding? The best-known comparison is militarized border enforcement, plus humanitarianism, posed against asylum seeking and irregular migration. But, more complex mobility occurs at these borders, including privileged and other differentiated and sorted mobilities. Interwoven with these mobilities, commerce of many scales and degrees of legality occurs, supporting complicated cultural worlds of informality and exchange. Borders require not just a political analysis, but also attention to capital. Importantly, borders (immediate and extended) have become increasingly important sites of export-oriented production in the world economy. The processes of interchange at borders, in turn, support important urban zones and other communities that merit close ethnographic study for their social and cultural complexity.
Distressful Situations, Non-Supportive Work Climate, Threats to Professional and Private Integrity
Authors: Tiselius Elisabet , Hägglund Elisabet , Pergert Pernilla
Published: December 2019

This chapter describes situations of distress and the working climate of healthcare interpreters in Sweden. A questionnaire focused on distressful situations was administered to interpreters with experience in healthcare interpreting. The results indicated that distress in healthcare interpreting could be traced back to ethically and emotionally challenging interpreting situations and working conditions, and a lack of respect for the interpreters' work. An interview study using Grounded Theory showed that interpreters' main concern was the threat to professional and private integrity. Despite the fact that in general the interpreting profession in Sweden may seem professionalized, interpreters struggle with dilemmas connected to less professionalized activities. Our study was conducted in Sweden, but we argue that the results can be generalized to other countries. Although differently organized in different countries, health care interpreters experience similar dilemmas. Equal access to equitable care can be effectively hindered by language barriers.
Mode Switching in Medical Interpreting and Ramifications on Interpreters' Training
Authors: Fragkou Effrossyni (Effie)
Published: December 2019

Mode switching is a frequent practice in healthcare interpreting, but has received very little attention. This research aims to bridge the aforementioned gap by investigating the instances of mode switching in interpreter-mediated healthcare encounters and the implications of this practice (or lack thereof) in managing effectively the administration of patients' care. To achieve this aim, the investigator created an online survey intended for trained healthcare interpreters alone. Seventy-five responses were collected over a period of three months (May to July 2019) and analyzed using a mixed methods approach. The objective was to demonstrate how interpreters envisage mode switching from the perspective of the training they received, the applicability of switching in relation to the nature of assignments that call for such shift in modes, the differences in mode switching between spoken and sign language, the institutional or other constraints (such as time limitations, number of participants, power differential among interactants) that call for or hamper mode switching, etc. The collected answers reveal a discrepancy between training and practice as well as between prescriptive requirements and reality in the field of healthcare interpreting. The respondents' comments allow the investigator to make key training recommendations.
Facilitating Legitimate Peripheral Participation for Student Sign Language Interpreters in Medical Settings
Authors: Stone Christopher , Hughes Thaïsa
Published: December 2019

The chapter explores student interpreters' learning of medical interpreting within a situated learning context that necessarily includes senior interpreters, senior healthcare practitioners, and deaf community members. Learning within this community of practice exposes students to the multimodal nature of sign-language interpreter-mediated interaction, including co-speech and no-speech gestures, linguistic and non-linguistic communicative actions, and the use of environmental tools and the situated use of language and interaction. Situated learning within the clinical-skills lab enables legitimate peripheral participation that closely emulates the authentic interpreting task. Data from roleplays based on a clinical-skills lab are analysed and examples are identified to show that student interpreters are driven by notions of language, rather than communication fidelity. The multimodal nature of the interaction within the situated learning environment facilitates the students' exposure to and learning of situationally driven interpreting choices.

Authors: Erfin Fauziah , Rikmasari Rasmi , Damayanti Lisda , Harmaji Andrie , Cahyanto Arief
Published: December 2019

Zirconia-based dental implant in Indonesia is rarely used, especially due to low demand. High production cost makes the price of each zirconia dental implant piece become expensive. The fabrication process of the dental implant using 3 mol% Yttria-stabilized Zirconia (3YSZ) as a starting powder, or being synthesized using ZrCl3 and YCl4 precursor were costly and complicated. The aim of this study is to investigate morphology and phase analysis in the ceramic dental implant which coated with carbonate apatite (CO3Ap). The industrial 3YSZ powder was compacted using a manual hydraulic press and sintered at 1500°C approximately to 11 mm pellet size. Specimens were pre-treated using 9% hydrofluoric acid (HF) before coated by CO3Ap, while others without treatment as a control. Then, the specimens were dipped into CO3Ap suspension and heat treated with temperature variable of 300°C or 500°C. The fabrication of specimen using manual hydraulic press creates monoclinic phase more than expected, while SEM discovered that the particle size of the specimen was 130-500nm. In conclusion, the effective method to coat the ceramic dental implant with CO3Ap was using 9% HF as a pre-treatment and calcinate in 300°C as confirmed in XRD and EDS.

Published: December 2019

Abstract. Various bioactive calcium phosphates such as hydroxyapatite (HA) and carbonate apatite (CO3Ap) have been widely studied due to their biocompatibility and osteoconductivity when implanted into bone defects. CO3Ap has the ability to adapt bone structure and induce bone regeneration; so that it can be categorized as resorbable bioactive materials. CO3Ap induced much stronger response such as cell adhesion and actin ring formation to osteoclast-like cells rather than HA. The aim of this study is to evaluate the bioactivity on zirconia (Y-TZP) coated with CO3Ap using simulated body fluid (SBF). Twenty Y-TZP ZrO2 disks with a 12-mm diameter and 1-mm thickness were employed as the samples. The disks were divided into two groups which the control group without CO3Ap coating and tested group with CO3Ap coating. Disks samples are dipped into CO3Ap suspension for one minute and stored in 37°C incubator for 24 hours. The disks were soaked in SBF for 1, 4, and 7 day(s) at 36.5°C. The obtained apatite crystals were characterized by scanning electron microscopy (SEM). It was found that the apatite formation on the tested group was greater than the control group. The EDS pattern showed the presence of Ca and P on the control and tested group after SBF soaking, which indicate the apatite deposition on the disks’ surface. However, the Ca and P on the tested group was higher compared to the control group. The formation of apatite layer on the disks’ surface is bioactivity indicator of CO3Ap.

Introduction. Synthetic coral scaffold is fabricated the mimicking of natural sea coral as a scaffold for bone regeneration [1]. Scaffold is performing functions as a micro environment for cells attachment, growth, proliferates, differentiates until it can form new bone tissue. The proper design is needed to produce the scaffold [2]. The purpose of this study was to investigate the characteristics of synthetic coral scaffold for micro environment of cells by observing cell attachment, hydrophobicity, and scaffold porosity. Experimental. Synthetic coral scaffold consists of bovine gelatin dan CaCO3 by weight, the concentration that be used are 4:6. Sodium citrate is used as dispersant. Thick film like scaffold was prepared for this study [1,3]. Vero cell line was used for observing cell attachment to investigate the biocompatibility the scaffold. The hydrophobicity was observed with distilled water droplets dripped on the scaffold surface, be analyzed in a photograph taken by the camera and then measured the angle. Percentage of porosity was measured using Archimedes law in absolute ethanol. Results and Discussion. Vero cells attached successfully into scaffold. Cell viability percentage is 91,77 % from the absorbance value of the MTT assay. It presented that the scaffold has biocompatibility character. However, the percentage of porosity is 55,85%, so the scaffold has enough porosity for cell attachment. Porosity serves for the diffusion of nutrients, gases and removes the residual metabolism resulting from cell activity that has grown on scaffold. The good porosity value of the scaffold is 50-90%. The higher the porosity value the better the scaffold. Hydrophobicity scaffold appears from the contact angle of 81.4°, the cohesion is greater than the adhesion. This shows the greater synthetic coral scaffold hydrophobicity, which is affected by surface roughness from scaffold porosity. The greater hydrophobicity will also prolong the degradation of the scaffold, thereby enabling cells to proliferate, differentiate and produce bone matrix. Conclusions. Synthetic coral scaffold provides the micro environment for cell, high hydrophobicity allows longer degradation for proliferation and differentiation of bone cells, and porosity that allows cells to be inserted within the scaffold.
Assessment of psychological stress during sleep using digital devices and its clinical relevance to future occupational health practice
Authors: Stipp Werner
Published: December 2019

Psychophysiological decompensation as a result of occupational stress leads to impairment of occupational performance. Adequate recovery from psychological stress is necessary to maintain occupational performance. It is possible to measure the psychophysiological status and recovery during sleep with health data streamed from biomedical digital devices. Such data, with reference to heart and sleep parameters, could be processed to reflect health status and whether there is a risk of psychophysiological decompensation. This article describes the interpretation of resting heart rate measures, heart rate variability, and actigraphy measures during regular sleep in relation to psychological stress. Interpretation of the health data should be done by informed health-care professionals in combination with clinical history taking. The article does not cover digital measurements while awake and active. The aim of this review article is to provide an evidence-based rationale to health professionals how to interpret digital health data profiles from biomedical devices in appraising psychological stress and recovery. The objective is to prevent the adverse impact of psychological stress on health. Specific lifestyle measures and therapy to manage psychological stress, such as exercise, diet, and cognitive behavioral therapy for insomnia, are not discussed in this article. Applications are especially relevant in the field of occupational health in preventing occupational burnout, achieving a healthy work-life balance, and sustaining a healthy working life. There are future implications with regard to disease prevention as a large proportion of chronic diseases, for example, hypertension, diabetes depression, and ischemic heart disease, are related to chronic psychological stress. Stress monitoring with biomedical devices should occur over periods of work and nonwork days.

Published: December 2019

Background and Objective:

Portable and readily accessible wellness devices can aid vital sign measuring for those interested in tracking their health. In this diagnostic accuracy study, we evaluated the performance of the VitalWellness device (VW), a wireless, compact, noninvasive device that measures four vital signs (VS) - blood pressure (BP), heart rate (HR), respiratory rate (RR), and body temperature (BT) - using the index finger and forehead.

Methods:

Adult volunteers with VS that fell both within and outside of the normal physiological range were enrolled to provide BP, HR, RR, and BT measurements using both the VW and Food and Drug Administration-approved reference devices. A subgroup of participants underwent an additional test to analyze the VW’s performance on HR and RR outside of normal physiological ranges. Statistical measurements were plotted on scatter and Bland-Altman plots. Sensitivity analyses to evaluate the VW’s performance by gender, skin color, finger size, and auxiliary activities were performed.

Results:

A total of 263 participants completed the study. On an average, systolic BP measured using the VW was 10 mmHg lower than that of the reference device (correlation coefficient r = 0.7), whereas diastolic BP was 3 mmHg lower (r = 0.6), and RR was 2 bpm lower (r = 0.7). VW HR and BT measurements were, on average, 1 bpm and 0.3°F higher than the corresponding reference measurements (r = 0.9 and r = 0.3), respectively.

Conclusion:

The VW device is well-suited for home-based, nonmedical monitoring of HR, RR, and BP. Further improvement in measurement accuracy is required to enable applications for medical use.
Thermal analysis and CW laser operation at 1.998 µm in end pumped Tm:YAP lasers

Published: December 2019

We report on thermal analysis and a continuous wave (CW) laser operation at (1.998µm) of end pumped Tm: YAP cylindrical laser rod. The Tm: YAP laser rod is pumped at a wavelength of 1.064 µm emitting from Nd: YAG laser source. A 3W incident pump power is used to generate a maximum laser output of 700 mW, representing 18% slope efficiency. The power of thermally induced lens in Tm:YAP laser rod is numerically analyzed and validated experimentally. The focal lengths of the thermally induced lens are directly measured using Shack-Hartmann wavefront sensor. We have detected blue up-conversion fluorescence emission before laser operation at 1.998 µm. The obtained experimental results were in good agreement with the numerical calculations.

Published: December 2019

O objetivo deste estudo foi a identificação automática de árvores em unidades amostrais circulares de 200, 300 e 400 m² em povoamentos de Eucalyptus spp. a partir de dados de TLS (Terrestrial Laser Scanning) no estado do Mato Grosso do Sul. Foram testadas três idades de plantio: árvores com 2 anos, sendo consideradas com desrama natural (E. urophylla) e sem desrama natural (E. grandis); árvores com 4,5 e com 5,5 anos, sem desrama (hibrido E. urophylla x E. grandis). A varredura laser em campo foi realizada com o equipamento Trimble TX5. Para a identificação automática das árvores, foi realizado um recorte na nuvem de pontos a 1,30 m do solo (DAP) e desenvolvido o algoritmo denominado fatia 2D. Foi possível a detecção de 98,3, 98 e 93,9% das árvores para as unidades amostrais de 200, 300 e 400 m², respectivamente. A distribuição espacial das árvores no plantio influenciou a identificação, ocasionando sombreamento das árvores mais distantes do equipamento laser. A adoção de varreduras simples deve ser aplicada somente em unidades amostrais pequenas, pois unidades amostrais acima de 200 m² acarretam maiores erros de detecção de árvores, o que pode gerar informações equivocadas nas estimativas dendrométricas da floresta.

Published: December 2019

El origen de muchos de los puertos que actualmente atraviesan la Sierra del Guadarrama se remonta a la época romana, constituyendo las vías de comunicación entre las dos Mesetas del centro peninsular. Desde entonces y hasta el siglo XVIII Somosierra, Navacerrada, La Fuenfría y Guadarrama se consolidaron como pasos de montaña en las rutas que unían Bayona (Francia) con Madrid y Andalucía. Fueron objeto de mejoras durante los reinados de los Borbones, y representadas por la cartografía española de la época. Debido a su situación estratégica, estos puertos jugaron un papel importante en las guerras, y especialmente en la Guerra de la Independencia fueron cartografiados por los ejércitos británico y francés. Esta importante colección de mapas anteriores y posteriores a 1814 permanece inédita en su mayoría. Los objetivos de la investigación son: 1/ estudiar y difundir tan importante patrimonio cartográfico; 2/ analizar las colaboraciones establecidas entre los cartógrafos españoles y extranjeros; y 3/ analizar la influencia de estos mapas en la cartografía del siglo XIX.
Digital survey: from new technology to everyday use, a knowledge path and challenge for scholars
Authors: Verdiani Giorgio
Published: December 2019

Which is the meaning of researching and working in the field of the digital survey at the beginning of the XXIth century? Are the scholars and professionals planning procedures and strategies or just producing an enormous amount of digital data which destiny will be a colossal data loss? Starting from a reflection about “where we are” after 20 years of active digital survey for built heritage this article will try to trace some points about how to start and to plan digital survey intervention when the task is not merely professional and when the new survey bases are supposed to be used in a “liquid” context. From the massive machines and procedures of the XXth century, producing quite “light” amount of data, in the last two decades these tools passed to be lightweight in their hardware, while the amount of gathered data increased continuously, in what it seems an unstoppable process. But massive data gathering maybe it is not knowledge by itself and the information society, especially in its next evolutions, will need contents and versatile data to support and link our present to the heritage values. A specific reflection on the value of digital survey and procedures will be held here not in the pretention of finding a stable paradigm but in the will of stimulating the discussion in a field often tempted by simply technical solutions.

Este artículo presenta los resultados de una experiencia de innovación realizada con alumnos de primer curso del Grado de Maestro de Educación Primaria. Partiendo de las tendencias globales a favor del fomento de capacidades de aprendizaje autónomo y colaborativo, un grupo de profesores miembros del Grupo de Innovación Docente EIE-GID, ha buscado una graduación progresiva en la dificultad y protagonismo a asumir por el alumnado en las tareas de aprendizaje. Se busca superar la dicotomía de clases teóricas y clases prácticas, empleando metodologías diversas, pero que comparten entre sus rasgos: fomentar la autonomía del alumno, procurar la motivación, adopción de riesgos y elaboración de respuestas alternativas, promoviendo responsabilidad, con opciones de experimentar y estimular el desarrollo de una actitud de superación permanente. Para ello, se plantean tareas que permiten hacer frente a acontecimientos imprevistos, tomar iniciativas, ser responsables y autónomos, movilizar recursos, comunicarse y relacionarse de manera efectiva y evaluar los efectos de las propias decisiones críticamente, de forma que los últimos temas se desarrollan basándose en la estrategia metodológica Aula Invertida. Al mismo tiempo, se diseña un protocolo de recogida de información y evaluación dirigido a los propios estudiantes para valorar el proceso y los resultados obtenidos. Las respuestas obtenidas muestran una valoración positiva sobre la experiencia, si bien los alumnos reclaman clases expositivas para aclarar las dudas sobre contenidos.
ABP: repensando los laboratorios de química
Authors: Cañas Cano M. F.
Published: December 2019

La enseñanza de química asocia teoría y experimentación en el laboratorio, así se esperan aprendizajes significativos, sin embargo, seguimos sin conseguir ese objetivo. En nuestra universidad, la asignatura Química General, se basa en Aprendizaje Basado en Problemas (ABP), y en el laboratorio, se busca enfoque verde. Además, el estudiante hace y analiza porque lo hace. Sin embargo, seguir proporcionando una guía, implica seguir “la receta” sin muchas oportunidadesde indagar y tomar decisiones propias, más acorde con la metodología ABP. Por ello, desde el año 2016, se propone que cada grupo plantee su propia investigación experimental. Cuentan con retroalimentación para reorientar su propuesta, de ser necesario. Los datos obtenidos, son básicamente cualitativos, y consisten en observación, análisis de la opinión estudiantil y del producto entregado, lo que ha permitido extraer conclusiones preliminares, respecto al trabajo autónomo, en equipo, la expresión oral y escrita.

All-solid-state polymeric screen printed and carbon paste ion selective electrodes for determination of oxymetazoline in pharmaceutical dosage forms
Authors: Rizk Mohamed Salem , Hussien Emad Mohamed , El-Eryan Rasha Tharwat , Daoud Amira Mohamed
Published: December 2019

All-solid state potentiometric ion selective electrodes have the merits of being portable, small and suitable for small volume samples. Herein, disposable home-made screen printed polymeric ion selective electrode (SPE) is developed for determination of oxymetazoline (OXM) in pharmaceutical nasal drops and drug substance. Ion selective electrodes with optimal potentiometric response were achieved by careful selection of the ion exchanger and plasticizer. A screen printed electrode utilizing oxymetazoline-tetraphenyl borate (OXM-TPB) as an ion exchanger and dibutyl phthalate (DBP) as a plasticizer exhibited a Nernstian slope of 59.5±0.5 mV/decade (n=3) over the concentration range from 1×10-5 to 1×10-2 M OXM (r = 0.9999) with a detection limit of 5.0×10-6 M. The electrode is useful over a wide pH range from 4.0 to 8.0. The electrode showed a high selectivity for OXM against several common interfering ions. The potential interference from benzalkonium chloride was easily eliminated by treatment the sample with KI. Comparable potentiometric characteristics including linearity, detection limit, pH range and selectivity pattern were obtained with a carbon paste electrode (CPE) comprising same ion exchanger and plasticizer. The electrodes were successfully used for the assay of OXM in the drug substance and in the dosage form in presence of benzalkonium chloride with high accuracy (±2%) and precision (%RSD ˂2.5). The proposed method is simple, accurate and precise.
Kinetic and equilibrium studies of adsorption of Pb(II) on low cost agri-waste adsorbent Jute Stick Powder
Authors: Alam Jahangir , Uddin Mohammad Nasir
Published: December 2019

A lingo-cellulosic material Jute Stick Powder was used as a biosorbent to remove Pb(II) ions from aqueous solution and the biosorption behavior was investigated as a function of pH, metal ion concentration, adsorbent dosages and agitation time. Sorption binding sites present in JSP was assessed by Infrared spectroscopy (IR) and Scanning Electron Micrograph (SEM). The determined experimental data were fitted to some common kinetic and equilibrium models. Langmuir isotherm and pseudo-second-order kinetic model gave better fit to experimental data. The study revealed that spontaneous ion-exchange and complexation process involved in the adsorption mechanism. When the repeated adsorption-desorption cycles were performed, JSP kept its adsorptive efficiency even after three cycles of reuse.

Published: December 2019

Daclatasvir (DAC), sofosbuvir (SOF) and ribavirin (RIB) have been recently co-formulated in tablet dosage form for the treatment of Hepatitis C virus infections. In this work, the resolution and quantitation of overlapped spectral signals was achieved by both univariate and multivariate algorithms. Pure component contribution algorithm (PCCA) as a novel approach was applied along with factor based partial least squares (PLS) algorithms using both full range and synergistic intervals (siPLS). Each drug could be determined at its λmax using PCCA, while PLS and siPLS were used for multivariate determination of the three components. Good linear relationships were obtained in the ranges of 5.45-16.35, 4.40-44.00 and 5.50-35.00 µg/mL for DAC, SOF and RIB, respectively, by PCCA. The PLS and siPLS models were built for the three compounds each in the concentration range of 2.00-10.00, 10.00-20.00 and 10.00-26.00 µg/mLfor DAC, SOF and RIB, respectively. Validation of the proposed methods was ascertained according to ICH guidelines for PCCA and through the use of internal and external validation sets for PLS and SiPLS models. The three methods were successfully applied for determination of DAC, SOF and RIB in pure form and in tablets.

Published: December 2019

Structures of alkaloid convolvine (1) isolated from Convolvulus subhirsutus and its derivatives-convolamine(N-methylconvolvine) (2) and hydrochloride of N-benzylconvolvine (3) have been determined by single crystal X-ray diffraction technique. Compounds were crystallized in monoclinic space groups having four molecules in unit cell. All compounds contain a bicyclic ring system of tropane, where piperidine rings in all case adopt chair conformation. Hydrogen atom and methyl- and benzyl-substituents located in nitrogen atom of studied compounds occupy equatorial positions. The substituent of tropane core- the veratroyloxy group containing in all compound molecules is an α-axial oriented relative to the tropane core. In crystal structures of compound 1 and 2, the molecules are located in the distance of van der Waals interactions. The H-bond between the anion Cl and the proton of the N atom is observed in the crystal of N-benzylconvolvine hydrochloride (Cl···N 3.337 Å, Cl···H 2.42 Å and Cl-H-N 175°).

Crystal data for C23H28N2O3 (4): orthorhombic, space group P212121 (no. 19), a = 10.636(2) Å, b = 11.208(12) Å, c = 16.725(13) Å, Z = 4, 1650 reflections measured (9.498° ≤ 2Θ ≤ 119.97°), 1650 unique (Rint = 0.0436) which were used in all calculations. The final R1 was 0.0608 (I > 2σ(I)) and wR2 was 0.1720 (all data). In alkaloids such as sarpagine and ajmaline exo, the substituents of alkaloids do not lead to conformational changes of a stable polycyclic framework. In the series of sarpagine, alkaloids form mono-salts in the tetrahedral nitrogen N4, and in indolines of the ajmaline type, the tetrahedral hybridization of the N1 and N4 atoms favors the formation of disols. In V. erecta alkaloids, the exomethylene fragment (C18-C19=C20-C21) of the polycyclic backbone always takes on the E-state.

Published: December 2019

In order to achieve the expected high performance, athletes must be physically, technically, tactically and socially ready as well as being psychologically ready and strong (Erdoğan & Kocaekşi, 2015). In this context, mental training of athletes is also important. Mental training means that athletes adjust and control their own sports behavior by adopting specific ways to promote psychological state. Aim of this research was to determine the level of mental training application of professional athletes and differences according to some variables. The sample consisted of 485 professional athletes (University Students) who are still competing in 4 different sports in Turkey (football, handball, basketball and volleyball). Data collection tool consisting of two parts was used in the research. In the first part of the data collection tool, a questionnaire consisting of the personal information of the participants was used. In the second part, Developed by Benkhe et al. (2017) and adapted to Turkish by Yarayan and İlhan (2018), “Mental Training in Sports Inventory” consisting of 5 sub-dimensions and a total of 20 items was used. Non-parametric tests were used for data analysis. Mann-Whitney U was used to determine the difference between two groups, Kruskall-Wallis analysis method was used to determine the difference between more than two groups. The average of total score of Mental Training Scale of the participants was determined as X̄ = 3.97. In other words, the level of mental training of the participants was found to be high. The sub-dimension with the highest average was found to be the Interpersonal Skills sub-dimension with the average of X̄ = 4.32, and the sub-dimension with the lowest average was the Mental Performance Skills sub-dimension with the average of X̄ = 3.70. In addition, different results were determined according to gender and ritual variables.

Published: December 2019

ASTM A743 CA6NM steel is used in the manufacturing of hydraulic turbines components. Multipass welding is commonly used for their fabrication or repairing. In this work, two different vibratory welding procedures were studied: vibration applied during welding (VWC) and vibration applied after welding (VSR). Results have shown that in both conditions, CA6NM steel presented a martensitic microstructure, in which the VSR welded joint presented column-shaped packets and fine martensite delineating the individual beads, while VWC joint presented grain refinement. Heat affected zones (HAZ) presented δ-phase in small amounts for both conditions in the regions which reached higher temperatures. VSR and VWC conditions presented similar behavior in terms of hardness, HAZ hardness values being close to those of the weld metal, except for the root regions, where higher values were obtained. Charpy-V results showed that HAZs presented higher impact values than those of the weld metal. The low impact values of the weld metal were attributed to presence of inclusions from the welding electrode.
