Published: February 2017

Abstract
The high temperature oxidation and hot corrosion behavior of nickel–iron-based superalloy are studied at 900 ° and 1000 °C. The significant role of alloying elements with respect to the exposed medium is studied in detail. The mass change per unit area was catastrophic for the samples exposed at 1000 °C and gradual increase in mass change was observed at 900 °C for both the environments. The exposed samples were further investigated with SEM, EDS and XRD analysis to study the metallurgical characteristics. The surface morphology has expressed the in situ nature of the alloy and its affinity toward the environment. The EDS and XRD analysis has evidently proved the presence of protective oxides formation on prolonged exposure at elevated temperature. The predominant oxide formed during the exposure at high temperature has a major contribution toward the protection of the samples. The nickel–iron-based superalloy is less prone to oxidation and hot corrosion when compared to the existing alloy in gas turbine engine simulating marine environment.

Authors: Snow James E. , Leach Matthew J. , Clare Bevin A. 
Published: February 2017

AbstractBackgroundEvidence-based practice (EBP) has been the focus of increasing attention in the teaching and delivery of both complementary and conventional healthcare. Western herbal medicine (WHM) is a system of complementary healthcare rooted in tradition. How WHM practitioners perceive, are prepared for, and use EBP, has to date been largely ignored. We therefore examined the use, opinion, skills, and training in EBP, and barriers and facilitators of EBP uptake, among herbal practitioners in the United States (US).MethodsThe study utilized a cross-sectional, descriptive survey design. A sample of US clinical herbalists was invited to complete a validated online questionnaire, the Evidence-Based practice Attitude and utilization SurvEy (EBASE).ResultsSeventy-four US herbal practitioners completed the survey (response rate=35 %). Participants demonstrated a generally positive attitude toward EBP (median attitude subscore 31 [possible range=8–40]), a moderate to high level of self-assessed skill in EBP (median skill subscore 46 [13–65]) and a moderate level of EBP uptake (median use subscore 12 [0–24]). Apart from a lack of clinical evidence in herbal medicine, there were few perceived barriers to EBP uptake among herbal practitioners. Access to the Internet, online databases and full-text journal articles were considered most useful in facilitating the uptake of EBP in WHM practice.ConclusionsRespondents’ attitudes, skill level, and uptake of EBP were generally consistent with other complementary and alternative medicine providers. Educational initiatives, including those focused on the appraisal and application of evidence, may help to optimize the use of EBP among WHM practitioners.

Published: February 2017

AbstractTape spring is straight, thin-walled, elastic strip with curved cross-section, which can replace traditional hinges by allowing for folding elastically and unfolded releasing stored energy with fewer component parts. This work is devoted to the properties of the folding and deployment of simple tape spring by numerical simulation and experiment method. Firstly, the folding process of tape spring is experimentally investigated using a specially designed test rig and verified by using nonlinear finite element ABAQUS/Standard solver. Then the moment-rotation relationships for symmetric bending are studied, the effects of subtended angle of section, total tape spring length, thickness and cross section radius on the performance of tape spring are investigated. Furthermore, the optimal model of tape spring structure design is established based on the response surface methodology (RSM) and parameter’s effective analysis, which aims at maximum strain energy during the tape-spring hinge deployment and subjects to allowable stress of tape spring. And the interior point algorithm is used to solve the optimal model. The optimal results are of great importance to the design of novel deployable structures with high stability, reliability and lightweight.
Enhancement: Ein Begriff zwischen Definitionshoheiten?

Published: February 2017

Zusammenfassung
Nach wie vor entzieht sich der Begriff ‚Enhancement‘ einer befriedigenden Analyse. Die vorliegenden Definitionen können zwar je für sich verbuchen, einen Kernbereich dessen herauszugreifen, worauf wir uns mit diesem Begriff beziehen, sie werden jedoch immer wieder mit Gegenbeispielen konfrontiert. Der vorliegende Artikel schlägt einen weiten Bogen von dieser sprachanalytischen Diagnose bis zu einem Vorschlag zur ethischen Bewertung von einzelnen Enhancement-Maßnahmen. Dieser Bogen umfasst eine Erklärung der sprachanalytischen Diagnose mithilfe der Sprachpraxis unterschiedlicher Disziplinen sowie einen Versuch, das verbindende dieser Sprachpraxen in eine interdisziplinäre Begriffsbildung zu verlängern, die auf Funktionalanalyse der Biowissenschaften und Funktionszuschreibung der Ethik und Anthropologie Bezug nimmt. Er schließt mit einem Verfahren für die Bewertung von Enhancement, welches die zugrundeliegenden anthropologischen Annahmen als interne Bestandteile der ethischen Argumentation versteht.

Published: February 2017

OBJECTIVE:
The goal of this study was to describe the prevalence, syndromes, and evolution of seizure disorders in children with cerebral palsy (CP) due to white matter injury (WMI).

METHODS:
For this population-based cohort study, brain MRI scans and medical records were reviewed in children in the Victorian Cerebral Palsy Register born between 1999 and 2006 recorded as having WMI. Children were excluded if they had features of an undiagnosed syndrome, associated cortical malformation or injury, or no medical contact in the preceding year. Included were 166 children with CP and isolated WMI due to presumed vascular insufficiency or hemorrhage; 87 were born preterm. Seizure and CP details were obtained from medical records and interviews, and EEG recordings were reviewed.

RESULTS:
Forty-one children (25%) had seizures beyond the neonatal period. Four children had West syndrome, which resolved with treatment. Thirteen children had febrile seizures that they outgrew. Thirty children had focal epilepsy with seizure manifestations and EEG discharges typical of early-onset childhood occipital epilepsy or childhood epilepsy with centrotemporal spikes; 23 have outgrown these seizures. Two children had idiopathic generalized epilepsy; it was ongoing in 1 child. Fourteen children had evolution from 1 epileptic syndrome to another. At last follow-up (median age, 12.7 years; minimum age, 9.7 years), 80% had not had a seizure for &gt;2 years.

CONCLUSIONS:
The electroclinical features of seizure disorders associated with CP and WMI are those of the age-limited, epileptic syndromes of childhood, with favorable outcome in the majority. The findings have important implications for counseling and drug treatment.

AbstractConsidered as a less hazardous piezoelectric material, potassium sodium niobate (KNN) has been in the fore of the search for replacement of lead (Pb) zirconate titanate for piezoelectrics applications. Here, we challenge the environmental credentials of KNN due to the presence of ~60 wt% Nb2O5, a substance much less toxic to humans than Pb oxide, but whose mining and extraction cause significant environmental damage.

<p>Las demarcaciones de tierras indígenas han causado grandes repercusiones en la historia brasileña. El objetivo principal de esta investigación es buscar entender el porqué de los conflictos relativos a los límites del derecho de propiedad indígena en el proceso de demarcación de territorio de los mismos. La problemática se encuentra en la necesidad de comprender lo que debe prevalecer frente a esos conflictos, si el derecho de propiedad asegurado en el artículo 5 de la Constitución Federal de 1988 o el derecho a las tierras tradicionalmente ocupadas previsto en el artículo 231 del mismo texto constitucional. La metodología adoptada fue la exploratoria-descriptiva y se trató de proponer posibles soluciones para sanear el problema presentado. Al final, se percibirá que los indígenas son apenas usufructuarios, así como también, que los conflictos existentes entre los territorios de demarcación indígena y las propiedades particulares pueden originarse de estudios antropológicos falseados por quienes los realizan, con el propósito de ampliar injustamente el territorio indígena. </p>
Tú, Usted y la construcción de la heterosexualidad masculina en hombres jóvenes, de clase trabajadora en Tolima
Authors: Zwisler Joshua James 
Published: February 2017

Este artículo examina la relación entre el uso del pronombre tú entre hombres de la clase trabajadora y la homosexualidad percibida de su uso. En Colombia, el uso de tú y usted entre hombres es una elección lingüística cuidadosamente considerada –es una elección que viene vinculada con la identidad sexual y género–. Mientras sí hay estudios estadísticos acerca de este fenómeno, la investigación anterior no ha examinado el razonamiento que existe tras esta elección de pronombres. En la sociolingüística y sociología moderna, la heterosexualidad no es vista como un aspecto fijo del ser de la persona como una identidad social que se maneja a través del discurso. Embarcando desde la Teoría de Identidad Social, esta investigación usó una serie de 20 extensas encuestas etnográficas en el Tolima, Colombia, para explorar la conexión que hay entre la heterosexualidad y la elección del pronombre. Después de analizar los datos usando el muestreo teórico, este trabajo expone la idea de que no es la homosexualidad sino la heterosexualidad la que es construida por el uso cuidadoso de pronombres y que esta última es una construcción delicada. En este contexto, el artículo concluye que la función sociolingüística de tú y usted constituye señales de contextualización para la distancia social requerida de la identidad heterosexual social de los hombres.

Published: February 2017

The aim of this study was to determine the levels of free fatty acids and carboxymethylcellulase activity (cmc-ase) activity of some protected fat-proteins base on in vitro Tilley and Terry method. Two sources of fat, i.e. crude palm oil and fish oil and three sources of protein i.e. skim milk, soybean flour and soybean meal were used in the formulation of protected fat-protein, and thus there were six treatment combinations. The filtrate from the in vitro test was analyzed for the levels of free fatty acids and cmcase activity. The result of this research indicates that different combinations of feed materials and fat give different content of free fatty acid in first stage and second stage in vitro, with the best results in the combination treatment of skim milk and palm oil that give the lowest result of free fatty acid concentration in fisrt stage in vitro (0.168%) and the highest result free fatty acid concentration in second stage in vitro ( 4.312%) . The activity of CMC-ase was not influenced by different sources of fat and protein. It can be concluded was that the protection of the combination between skim milk and CPO gives the highest protection results.

The aim of the study was to evaluate the effects of inclusion plant source of n 3 fat in the form of alpha-linolenic acid (ALA, 18:3n-3) on the diets of layers on production performance and physical quality of eggs. A total of 125 Hy-Line Brown hens (38 weeks old) were placed at individual cages and assigned to five dietary treatments. The dietary treatments were supplemented with 0, 1.5, 3.0, 4.5 and 6.0% purslane meal. Laying hens were fed for five weeks following a seven day adaptation period. Water and feed were provided ad libitum. Feed intake (FI) measured weekly and feed consumption ratio (FCR) was calculated at the end of the trial. A total of 25 egg yolk samples of day 35 (n = 5 egg yolks for each treatment) were collected to analyse physical quality of eggs. The data were analyzed using Analysis of Variance (ANOVA). Differences between treatment means were further analyzed using Duncan's New Multiple Range Test (DMRT). Results showed that the incorporation of plants rich in ALA did not modify FI, FCR, and egg production. Supplementation of purslane meal in the diets had no effect on physical quality of eggs, including egg weight, yolk weight, albumen index, yolk index and Haugh Unit (HU). The average of egg weight and yolk weight were 60,5 and 15.3 g, respectively. Diet containing purslane meal increased yolk colour. In conclusion, laying hens that fed diet supplemented with purslane meal rich in ALA improved yolk colour and did not change the production performance of the laying hens or the qualities of the eggs.
