Study Of Factors Affecting The Thermal Conductivity Of Iraqi Bentonite
Authors: Journal Baghdad Science
Published: March 2019

Thermal conductivity of compacted bentonite is one of the most important properties where this type of clay is proposed for use as a buffer material. In this study, Lee's disc method was used to measure the thermal conductivity of compacted bentonite specimens. The experimental results have been analyzed to observe the three major factors affecting the thermal conductivity of bentonite buffer material. While the clay density reaches to a target value, the measurement is taken to evaluate the thermal conductivity. By repeating this procedure, a relationship between clay dry density and thermal conductivity has been established in specimens after adjusting the water contents of the bentonite by placing its specimens in a drying oven for different periods. So relationships of thermal conductivity with each of these major factors (clay density, water content, and sand volume fraction) are established in this study. The relevance of these relationships be analyzed together using experimental data on many compacted bentonites.

Published: March 2019

Core Ideas

There was a positive correlation between nitrogen concentration in grain and between Layer 1 and Layer 4 (Gtotal).

The nonfoliar organs were involved in to determine the nitrogen vertical distribution in winter wheat canopy.

The nitrogen contributions of various organs to grain nitrogen were determined.

The role of N remobilization in nonfoliar and foliar organs influences the N vertical distribution and accumulation of N in grain. We hypothesized that the N concentrations in foliar and nonfoliar organs affect the remobilization, vertical distribution, and accumulation on N in grain. A 2‐yr field experiment was conducted to evaluate the effects of N input and mulching practice on N remobilization and N vertical distribution in the canopy of winter wheat (Triticum aestivum L.). The results showed that foliar organs had higher N concentration than nonfoliar organs in all treatments. Among the nonfoliar organs, the flag leaf sheath had the highest N concentration, followed by glumes and rachillae combination, while the stem had the lowest N concentration at anthesis and maturity. In the different internode segments of the stem, N concentrations decreased with grain filling, except for the exposed part of the peduncle. There was a top‐to‐down decline in N concentration within the canopy. Foliar organs contributed the most N to grain followed by the stem and the glumes and rachillae combination. The N286 treatment significantly improved N accumulation, remobilization, and vertical distribution in the canopy and N content in grain. Nitrogen concentration in the grain was positively correlated with the difference in N concentrations between apical and basal vegetative modules.

Authors: Chauhan Ajay , Grewal Ajmer S. , Pandita Deepti , Lather Viney
Published: March 2019

Background:

Peroxisome proliferator-activated receptor (PPAR) δ is expressed universally in the entire tissues, particularly in those concerned with the lipid metabolism. PPAR δ stimulation alters body’s energy fuel preference to fat from glucose and shows up as an emerging pharmacological target for the treatment of metabolic disorders.

Methods:

A new series of cinnamic acid derivatives was synthesized and evaluated for the antidiabetic and antiinflammatory activities in the animal models followed by in silico docking studies to determine the binding interactions for the best fit conformations in the binding site of the PPARδ protein.

Results:

Amongst the synthesized molecules, compound 3 showed higher antidiabetic activity in oral glucose tolerance test and compound 1 showed higher antiinflammatory activity in the carrageenan induced rat paw oedema method. The in vivo study results were supported by the similar in silico molecular docking results. Most of the synthesized derivatives showed drug likeness as depicted via Lipinski’s rule of 5.

Conclusion:

These molecules can serve as the early hit molecules for the discovery of safe, effective and bioavailable PPARδ agonists for the potential treatment of various metabolic disorders.
HPLC-DAD-Q-TOF/MS-Based Screening and Analysis of the Multiple Absorbed Bioactive Components in Rat Serum after Oral Administration of Xiexin Tang
Authors: Wang Xiaoyu , Li Shujiao , Wang Yuqing , Hu Rui
Published: March 2019

Background:

Xiexin Tang (XXT) is a classic Traditional Chinese Medicine (TCM) formula
that has been used in herbal clinics for more than 1800 years. Recently, many studies have investigated
the pharmacological effects and chemical composition of XXT. However, there is little information
about systematic studies on the material basis of its efficacy. In the present study, the serum pharmacochemistry
technique and HPLC-DAD-Q-TOF/MS were performed to screen and analyze the multiple
absorbed bioactive components and metabolites of orally dosed XXT in rat serum.

Methods:

Bio-samples and herbal extracts were analyzed and detected by HPLC-DAD-Q-TOF/MS.
Upon comparison of the chromatograms of the single-constituent decoctions with that of the XXT formulation,
the peak quantity and peak intensity of the formulated decoction showed some variation from
those of the single-constituent decoctions.

Results:

Twenty-one serum-adsorbed constituents were identified after intragastric administration of
herbal extracts, of which 8 originated from Rhei Radix et Rhizoma (RRR), 5 from Coptidis Rhizoma
(CR), and 8 from Scutellariae Radix (SR). The results showed that the main adsorbed constituents in the
serum were anthraquinones, anthrones, chromones, and butyrophenones, alkaloids, and flavonoids.

Conclusion:

The results demonstrate that an effective and reliable analytical method is set up for
screening the bioactive components of Chinese herbal medicine, which provided a meaningful basis for
further pharmacology and active mechanism research of XXT.
Targeting Epidermal Growth Factor Receptor in Non-Small-Cell-Lung Cancer: Current State and Future Perspective
Authors: Bao Shui-Ming , Hu Qing-Hui , Yang Wen-Ting , Wang Yao , Tong Yin-Ping , Bao Wen-Dai
Published: March 2019

Background:

Lung cancer is one of the leading cause of cancer death worldwide, the most common
histological type of lung cancer is non-small cell lung cancer (NSCLC), whose occurrence and development is
closely related to the mutation and amplification of epidermal growth factor receptors (EGFR). Currently , a
series of targeted drugs were developed on the inhibition of EGFR such as epidermal growth factor receptortyrosine
kinase inhibitor EGFR-TKI and monoclonal antibody (McAb).

Objective:

We sought to summarizes the current drugs targeting Epidermal Growth Factor Receptor in nonsmall-
cell-lung.

Methods:

We conducted a comprehensive review of the development and application of EGFR-TKI and McAb
which targeted EGFR in NSCLC and compared the mechanisms of PROTAC with the traditional inhibitors.
Results: The drugs targeted EGFR in NSCLC have been widely used in clinic practices. Compared to traditional
chemotherapy, these drugs excel with their clear and specific targeting, better curative effects, and less toxic and
side effects. However, the mechanism comes with some insurmountable weaknesses like serious toxic and other
side effects, as well as proneness to producing drug resistance.

Results:

The drugs targeted EGFR in NSCLC have been widely used in clinic practices. Compared to traditional
chemotherapy, these drugs excel with their clear and specific targeting, better curative effects, and less toxic and
side effects. However, the mechanism comes with some insurmountable weaknesses like serious toxic and other
side effects, as well as proneness to producing drug resistance.

Conclusion:

The emerging PROTAC (Proteolysis Targeting Chimera) technology has been successfully applied
to selective degradation of multiple protein targets, including EGFR. It also highlights the potential and challenges
of PROTAC therapy regarding future combination therapeutic options in NSCLC treatment.

“Whey Aye My Good Sir”: Has Cheryl Fernandez-Versini’s Accent Moved from Tyneside English to RP?
Authors: Wallace Victoria
Published: March 2019

This article analyses the speech of Cheryl Fernandez-Versini (nee Tweedy, formerly Cole), henceforth “Cheryl” , who experienced rapid geographical and socioeconomic mobility between 2002 and 2014. In 2002, Cheryl was a working-class 19-year-old from Newcastle Upon Tyne, north-east England. Since then, she has risen to fame on the talent show Popstars: The Rivals , in the girl band Girls Aloud , through her marriage to footballer Ashley Cole, and through her work as a judge on The X Factor , among other things. This paper seeks to analyse the effect this has had on her accent.Four recordings between 2002 and the present day are analysed to discuss changes to her original Tyneside English (TE) accent, specifically through the changing phonetics of the FACE  and the GOAT  vowels. These changes are discussed in terms of both the TE speech community and Cheryl’s personal experiences. The  two vowels have traditional diphthongs in TE which are different from the diphthongs in Received Pronunciation (RP). However, these vowels have been found to be undergoing dialect levelling, with many TE speakers producing them as the monophthongs found in the rest of the North (Watt 2000, 2002). The paper therefore investigates whether Cheryl follows the pattern of other TE speakers or moves towards RP.The recordings used are taken from online videos of interviews. The first time point studied is 2002, when Cheryl first rose to fame through Popstars: The Rivals , in which her GOAT  and FACE  vowels are shown to be the Northern monophthongs which have resulted from dialect levelling in TE. The intermediate time points studied are 2006 and 2011. In 2006, Cheryl was engaged to Ashley Cole and had been living and working in the south of England for 4 years. Both vowels move closer to RP in position but remain monophthongal. The 2011 recording is an interview in the US, during Cheryl’s brief career on American X Factor. The data for this time point are particularly interesting as the position of the vowels varies more, and the average position of both vowels does not fit the pattern of change, indicating style-shifting. The 2014 recording was the most recent interview of substantial length which could be found at the time of data collection. The analysis shows that Cheryl’s GOAT  vowel is significantly closer to RP than it was in 2002, despite remaining a monophthong, while her FACE  vowel appears to have become a diphthong as in RP.The results show that Cheryl does undergo lifespan change in these two vowels, being closer to RP at the time of writing than in 2002. However, the two intermediate time points studied show that these vowels do not change in parallel, as predicted by Watt (2000). The intermediate time points, in particular the 2011 data, give support to the conclusions of Rickford and Price (2013) and Bowie (2009) that in order to fully understand data on lifespan change, intermediate time points and factors other than age must be taken into account.
The Young and the Old: (t) Release in Elderspeak
Authors: Michaelov James
Published: March 2019

Elderspeak refers to a speech style used when talking to the elderly. The aim of this study was to find out whether a higher rate of standard phonetic variants of phonemes is a feature of elderspeak. To test this, the (t) release in the speech of the radio presenter Kirsty Young was analysed, comparing her speech towards younger and older guests. A significant correlation was found between her rate of (t) release and the age of the guests. After analysing the results, an alternative account of elderspeak is presented as well as possible avenues of future research.
The Effects of Forensically Relevant Face Coverings on the Acoustic Properties of Fricatives
Authors: Saigusa Julie
Published: March 2019

This forensically motivated study investigates the effects of a motorcycle helmet, balaclava, and plastic mask on the acoustics of three English non-sibilant fricatives, /f/, /θ/, and /v/ in two individuals. It examines variation within the individual as an effect of the physical environment. Two speakers recorded a list of minimal pairs in each of the three guises and with no face covering. The results showed that facewear significantly affected fricative intensity and the four spectral moments: centre of gravity, standard deviation, skewness, and kurtosis. The acoustic changes caused by facewear have implications for judging the reliability of earwitnesses’ content recall and voice identification as well as forensic speech scientists’ examination of content and speaker identity in disputed recordings.

O Sistema Único de Saúde (SUS) pode ser declarado como uma das poucas políticas que nasce do povo para o povo. A construção do SUS como política social converge com o pensamento de redemocratização do Brasil e a defesa dos direitos do povo no Estado Brasileiro. Não é à toa que o slogan “Saúde e Democracia” iluminavam as bandeiras de luta que vislumbravam um sistema de saúde que respondesse ao conceito de saúde para além da assistência e da prestação de serviços de saúde à população.
Future iused to denote habitual actions in the vernacular of the Sirinic Zupa in the northern Sar Mountains
Authors: Veljovic Bojana , Mladenovic Radivoje
Published: March 2019

This paper analyzes the use of Future I to denote habitual actions in the
vernacular of Sirinic. The analysis shows that Future I is a high-frequency
unit when it refers to effects of what happened in the past as a custom,
habit or part of a sequence. The use of Future with this meaning developed
as its secondary trait, but this form was eventually suppressed from other
domains of use and it was narrowed down to denoting a habitual action. The
basic syntactic and semantic features of this future form with this time
reference are its reference to a repeated action or a succession of events
and its ability to denote the timeline of the effects of the action and its
reference to wishes and commands more clearly. Furthermore, a future
referring to the past is stylistically marked and thus appears as an
expressive unit within the system, which is why it is typical of emotional
discourse. In the Shtokavian area, Future I for habitual actions is only
known in the Sirinic vernacular and in a few neighboring ones concentrated
around the Sar Mountains. On the other hand, this unit is also frequent in
Macedonian and Bulgarian and in some non-Slavic languages spoken in the
Balkans, which is why the authors also investigate the presence of this
feature in those languages.

Identifying New Knowledge Areas to Strengthen the Project Management Institute (PMI) Framework
Authors: Iyer K. Chandrashekhar , Banerjee Partha S.
Published: March 2019

In an increasingly volatile, uncertain, complex and ambiguous (VUCA) world, managers of capital projects are under relentless pressure to consistently meet their performance expectations. At the execution stage, managers have to constantly orchestrate competing demands on scare resources and, simultaneously, manage project operations to meet time, costs and quality compliances. This calls for simple methods to distinguish factors that could cause execution stage delays and prioritise their remedial actions. The objective, therefore, was to propose and test a methodology through empirical evidence, which could be useful for managers to focus on the distinguishing factors (rather than on all factors) to achieve execution excellence. We used a three-stage methodology leveraging the existing Project Management Institute (PMI) framework to define variables and then tested the methodology using case data generated from projects adopting a grounded theory approach. A set-theoretic, multi-value qualitative comparative analysis (QCA) tool helped appropriately configure this empirical case data and a subsequent Boolean minimisation technique then identified the distinguishing factor(s) that explained superior project schedule performance. The results corroborated literature findings. Two contributions emerged from this study: (a) our methodology enabled a richer analysis of the case than what would have been possible by adopting a more conventional approach; and (b) there is a potential for a domain-specific extension of the PMI framework to cover technology transfer projects having their unique knowledge areas.

Este articulo presenta el diseño e implementación de un sistema para el análisis cinemático y cinético del salto vertical. El sistema se basa en el uso de técnicas de videogrametría y procesamiento de imágenes para registrar la secuencia del movimiento ejecutado. Se diseñó y desarrolló un programa aplicativo para el registro y procesamiento de los datos obtenidos por medio de la cámara, utilizando las herramientas de procesamiento digital de imágenes y la interface de usuario GUI que ofrece Matlab. En el programa se dispone de un modelo biomecánico bidimensional de los miembros inferiores que, a partir de cinco puntos anatómicos referenciados, determina los valores de: recorrido, velocidad, aceleración, fuerza, potencia y ángulos articulares de los miembros inferiores, a lo largo de la ejecución del salto. Se realizaron pruebas experimentales con cinco sujetos utilizando un protocolo para el salto vertical, para comparar las curvas entregadas por el software con respecto a las curvas teóricas encontradas en la literatura y datos obtenidos por otros sistemas de medición. A pesar de las limitaciones del sistema referentes al análisis bidimensional del salto vertical, se lograron obtener resultados satisfactorios con referencia a otros métodos utilizados actualmente y a instrumentos específicos para mediciones.

Con el fin de recuperar parte del concentrado presente en las aguas residuales producto del manejo de 400 cerdos de la finca Canaguaros (Rivera Huila), y ser utilizado como alimento para bovinos, se realizaron en laboratorios de la Facultad de Ingeniería una prueba para la separación de la fracción sólida (concentrado) de la líquida mediante un proceso de sedimentación y una prueba de secado del concentrado recuperado por acción del sol; para caracterizar el efluente se tomaron muestras que en el Laboratorio de Aguas de la Universidad Surcolombiana por métodos estandarizados se les determinaron pH, DBO, SS, N, P, Grasas y Aceites. Los resultados de la caracterización fueron pH = 6.7, DBO = 3250 mg/l, SS = 8750 mg/l, G y A = 28.2 mg/l, N = 258 mg/l y P = 1020 mg/l. El tiempo de sedimentación de 2 horas 30 minutos obtenido, es el parámetro que se recomienda para dimensionar tanques sedimentadores de concentrado. El tiempo de secado del concentrado en un secador parabólico tipo invernadero con piso en concreto es de 8 horas. Se espera recuperar 402 g/Kg de concentrado utilizado por cerdo y obtener porcentajes de remoción DBO = 13%, SS = 78%, G y A = 75%, N = 42% y P = 57% considerados como buenos.

USING A GENRE-BASED APPROACH TO PREPARE UNDERGRADUATE STUDENTS FOR AN ENGLISH THESIS DEFENCE EXAMINATION: AN EXPERIMENTAL STUDY TO ADDRESS THE ‘PEDAGOGICAL CONTROVERSY’
Authors: Samad Iskandar Abdul , Adnan Zifirdaus
Published: March 2019

A great deal of research has been conducted on genre based approach, suggesting that it is an important approach. Its importance is also indicated by the fact that it is adopted in the 2004 and 2006 National English Curricula of Indonesian secondary schools. However, the pedagogical benefit of this approach to English language teaching is still controversial. Some research has shown that it is effective to develop language competence, some has not. The fact that since the adoption of this approach in the 2004 Indonesian National Curriculum the quality of Indonesian English language teaching at Indonesian schools has not significantly improved complicates the issue further. The present study was intended to contribute to the debate. It is an experiment to discover whether the approach can help improve the performance of students in university thesis defence examinations. The study was conducted at a university level because of an important practical issue, that is complaints among members of the academic community about the poor performance of undergraduate (UG) students in the thesis defence examination (TDE) event at Indonesian universities especially in Aceh. It was believed that even though students were competent in speaking general English, they were poor in their oral thesis defence performance. This study concludes that, with some conditions, it can help at least in some respects.
PERENCANAAN BAHASA DI INDONESIA BERBASIS TRIGLOSIA
Authors: Ibrahim Gufran Ali , Mayani Luh Anik
Published: March 2019

For regions or countries with language plurality, which gives impact to cultural plurality, language planning becomes a complex matter. This study proposes concepts on language planning which can be applied in multilingual countries like Indonesia. Based on literary research on language situations in some countries, this study describes the language situation in those countries and compares it the language situation in Indonesia. The conclusion is that the implementation of language planning in Indonesia needs various strategies; there is no single strategy which can be well applied for the whole linguistic situation in the country. Language planning in Indonesia should be started by corpus planning as a strategy to preserve local vernaculars from language endangerment. The next step is determining regulation in order to divide the domains of language use: (1) the use of Indonesian language and local vernacular(s)/colloquial(s) in diglossic regions and (2) the use of Indonesian language, the “intermediate” language and local vernaculars(s) in triglossic regions.
