Authors: Chougale Ravindra , Kasai Deepak , Nayak Shilpa , Masti Saraswati , Nasalapure Anand , Raghu Anjanapura V
Published: August 2019

In the current study, poly(vinyl alcohol) (PVA)/titanium dioxide (TiO2)-based nanocomposite films were prepared using the solution-blending and solvent-evaporation techniques. The tensile properties and phase morphology of the prepared PVA/titanium dioxide nanocomposite films were investigated using universal testing machine (UTM) tests and scanning electron microscopy, respectively. Further, the water contact angles and antifungal activities of the composite films and their interactions were evaluated by using Fourier transform infrared spectroscopy (FTIR). The results of UTM tests revealed that the mechanical properties increased up to a proportion of 6% titanium dioxide nanoparticles. The addition of titanium dioxide nanoparticles to the PVA matrix resulted in smooth and homogeneous phase morphology except for the PVA matrix with 4% brahmi plant extract titanium dioxide nanoparticles. The water contact angle and antimicrobial activity confirmed that the hydrophilic nature slightly increased, and antifungal activity showed a significant rise in the composite films. Intermolecular interactions through hydrogen bonding between the composite films were confirmed by the FTIR study. The results of a packaging study clearly suggest that the composite films have good storage properties and they can be used as environment-friendly materials with slight modifications. The prepared films can find potential applications in food packaging for storage of foodstuffs.

Authors: Rocha Loredo Ana Guadalupe , Ramírez Marcial Neptalí
Published: August 2019

Se cuantificó la producción de hojarasca en comunidades sucesionales del boque de pino-encino en dos localidades de Chiapas y se evaluó simultáneamente la descomposición de hojarasca de siete especies ( Alnus acuminata subsp. arguta, Chiranthodendron pentadactylon, Clethra suaveolens, Liquidambar styracifl ua, Quercus crassifolia, Quercus sapotifolia y Pinus oocarpa ). Después de un año, la máxima acumulación de hojarasca se registró en el bosque de pino-encino (7.59±0.29 Mg•ha-1•año-1), seguido por el bosque de encino (6.58±0.27 Mg•ha-1•año-1), el bosque de pino-encino-Liquidámbar (5.33±0.18 Mg•ha-1•año-1), el bosque de pino (5.18±0.19 Mg•ha-1•año-1) y el menor aporte anual de hojarasca se registró en las parcelas bajo restauración forestal (2.43±0.13 Mg•ha-1•año-1). Después de 10 meses, la mayor descomposición de hojarasca ocurrió en Alnus acuminata (61-67%), independientemente de la condición forestal; en el resto de las especies la descomposición varió de 34-52% y no se detectaron diferencias entre las condiciones del bosque.
Remoción de semillas, herbivoría y reclutamiento de plántulas de Brosimum alicastrum (Moraceae) en sitios con manejo forestal contrastante de la selva maya, Quintana Roo, México
Authors: Gutiérrez Granados Gabriel , Dirzo Rodolfo
Published: August 2019

En este trabajo se evaluó el impacto de la extracción forestal sobre la remoción de semillas, herbivoría y establecimiento de Brosimum alicastrum . Para esto, se utilizaron una serie de exclusiones experimentales colocadas en sitios con manejo y sin manejo forestal. Los resultados muestran que la remoción de semillas y el establecimiento de B. alicastrum fue mayor en las zonas de extracción forestal. La herbivoría fue más intensa en las zonas de reserva y estuvo asociada a una mayor abundancia de B. alicastrum lo que sugiere la existencia de efectos denso-dependientes en las zonas de reserva; en las zonas de extracción forestal no existió esta asociación, lo que puede estar explicando el establecimiento diferencial entre condiciones de admanejo. Los resultados indican que la extracción forestal puede alterar procesos denso-dependientes y causar la sobre-representación de algunas especies afectando a largo plazo la diversidad de las selvas.

The main objectives of this study were to identify the edaphic factors that could be related to vegetation distribution in the lower-Cheliff plain (35.750° - 36.125°N, 0.5° - 1°E) one the largest salted plains of northwestern Algeria and to establish the relationships between these soil factors and the main plant communities. Soil and vegetation data were obtained from 133 relevés. Species in Chenopodiaceae and Asteraceae were dominant in the salted plain. Soil variables measured included electrical conductivity, elevation, soil texture, soil structure, organic matter, CaCO3, pH, Ca++, Na+, Cl-, CaMg and color of soil. Multivariate analyses including detrended correspondence analysis (DCA) and redundancy analysis (RDA) were performed to analyze the collected data. The results showed that the vegetation distribution pattern was mainly related to conductivity and elevation. Separation of relevés into groups according to the first two axes of RDA provided four vegetation units, each one composed of several diagnostic species with highly significant fidelity value according to Fisher’s test. The theoretical maps produced by kriging revealed a close relationship between these vegetation units and conductivity.
The Dryopteris patula complex (Dryopteridaceae) in Mexico: morphometric analyses
Authors: Hernández Hernández Victoria , Terrazas Teresa , Delgadillo Moya Claudio
Published: August 2019

We studied collections from four species of the Dryopteris patula complex (D. cinnamomea, D. patula, D. rosea, and D. rossii) to identify the morphological characters that distinguish them from one another. D. maxonii and D. wallichiana were included as comparative species to evaluate characters that distinguish species within the complex. Quantitative characters were examined through principal component and canonical discriminant analyses, and both qualitative and quantitative characters were used to obtain phenograms. Multivariate analyses determined that basal pinna length, stipe scale length, number of pinna pairs, and frond length are the variables that discriminate among D. rossii and the other species of the complex. The phenogram showed two groups. One included D. maxonii and D. wallichiana , while the second grouped the four species of the complex. These species were distinguished by the shape and margin of their rhizome scales, color of stipe, and shape of the blade. A combination of morphological characters supports the recognition of the four species as valid. An identification key is given and a taxonomic treatment is presented for each of the taxa.
¿Hay asincronía demográfica entre poblaciones locales de Tillandsia recurvata ? evidencias de su funcionamiento metapoblacional
Authors: Valverde Teresa , Bernal Rocío
Published: August 2019

Se estudió la demografía de nueve poblaciones de la epífita Tillandsia recurvata establecidas sobre Prosopis laevigata en la región de Tehuacán, Puebla, para evaluar si existía asincronía demográfica entre ellas, condición fundamental para la persistencia de una metapoblación. Estas poblaciones diferían en términos del tamaño del árbol (volumen de la copa) y de su número de individuos. Se construyeron dos matrices de Lefkovitch por población, una para 2001-2 y otra para 2002-3. Las estructuras poblacionales difirieron entre poblaciones: la proporción de plántulas fue mayor en los árboles pequeños, mientras que en los árboles grandes se observó una mayor proporción de adultos. Los valores de ? variaron entre poblaciones y entre años, pero no mostraron ningún patrón claro de variación. Se encontró una correlación positiva entre ? y el tamaño poblacional, pero sólo para 2002-3. Las poblaciones estudiadas mostraron un comportamiento demográfico asincrónico, favoreciendo la persistencia de la metapoblación.

Authors: Alam Md. Zahangir , Mizan Farhana Binte
Published: August 2019

Being the digital natives, instructors and learners of this cutting edge era largely depend on technology to intensify their learning and teaching process inside and outside the classroom. Many devices are found to make language teaching more effecting and alluring for the learners. Arguably, both parties’ teachers and students are receiving some benefits after including this addition of modern science in their learning and teaching process.  This study focuses on how CALL aids learning and teaching to this integral component of the language. It is found that certain software which were installed in the computer offer learners help immensely to internalize ESL vocabulary. Indeed, accesses of visual imagery on computer screen aids learners make concrete images of uncommon vocabulary which support very effectively L2 vocabulary acquisition. Most notably the study has found that CALL eases learning points for the special children besides it helps learners retain the vocabulary which they learn. With the availability, teachers can present lesson in realistic fashion which guide learners internalize the L2 vocabulary. Teachers are found ambivalent about including CALL tools in their daily taught lessons as technology always carries some fringe crisis though none expressed any negative feelings about the worth of CALL in case of vocabulary acquisition.
Decoding Sense in Caricatures: A Study in Semio-stylistics
Authors: Jaashan Hasan Mohammed Saleh
Published: August 2019

Icon, index, and symbol are the trichotomy parts of sign proposed by Peirce. The relationship between sign and object in them generates more and different interpretants. These parts focus primarily on non-verbal communication. Part of that nonverbal genre is caricaturing. Caricatures draw the attention of readers because caricaturists concretize the intended meaning in an overstatement style of drawing. This paper seeks to investigate how Peirce's terms of the sign; icon, index, and symbol are integrated into each caricature to complement the intended meaning of the caricaturists. Stylistically, it asks what are the foregrounding and de-familiarization features of these caricatures? It concludes that caricatures are mere connection between signs and objects results in formulating specific perception about the highlighted phenomena. Moreover, in caricatures there are some idiosyncratic aspects that make them de-familiarized and foregrounded. The researcher collected samples of caricatures from different newspapers to support his arguments.
Manifestation of Chinese and American Values in The Wedding Banquet
Authors: Yu Jiefei
Published: August 2019

This paper mainly focuses on various cultural values and conflicts represented in the film The Wedding Banquet. In contrast with the civil marriage ceremony of American style performed in a Registry Office, the Chinese wedding is much more luxurious, filled with lots of over-elaborated formalities that are necessary in Chinese culture. The ceremony itself is considered more important than the notarization. Taking the subject of sexual orientation as a metaphor for larger cultural issues, the film is examined as identity confusion and inevitably, the pursuit of identity reconstruction. Through Wei-Tung’s psychological struggles between Chinese traditional values and his homosexual desires, the film explores the possibility of a re-considered perception of identity for an Asian diasporic gay. Given the historical baggage brings with them, the process of the construction of identity for the immigrant is continuously dynamic and ongoing. After the implicit negotiations between ethnicity, sexuality, and patriarchy, the film story moves to reconciliation. This suggests that in such an era of multiculturalism, people had better come to realize their individual identities of diversity and complexity.
Investigating the Differential Effects of Formative and Summative Assessment on EFL Learners’ End-of-term Achievement
Authors: Mahshanian Amir , Shoghi Reihane , Bahrami Mohammad
Published: August 2019

In this study, an attempt has been made to highlight the importance of summative assessment in conjunction with teacher-based (formative) assessment on the learning. 107 advanced EFL learners in 3 classes were selected and grouped based on the type of assessment they received. Participants in this study were given tests for two main reasons. First, a general test of proficiency was administered in order to place the learners in different proficiency levels. Second, in an attempt to compare learners’ improvement based on different types of assessment within a 4-month learning period, an achievement test of the course was given two times, as pre and post-tests. The data obtained through learners’ scores on achievement tests were analyzed and then compared using ANOVA, ANCOVA and t-test. In light of the results of this study, it can be argued that a combination of formative and summative assessments can lead to higher achievements of EFL learners than either formative or summative assessment separately.

Stress Drops and Directivity of Induced Earthquakes in the Western Canada Sedimentary Basin
Authors: Holmgren Joanna M. , Atkinson Gail M. , Ghofrani Hadi
Published: August 2019

The Western Canada sedimentary basin (WCSB) has experienced an increase in seismicity during the last decade due primarily to hydraulic fracturing. Understanding the ground motions of these induced earthquakes is critical to characterize the increase in hazard. Stress drop is considered an important parameter in this context because it is a measure of the high‐frequency content of the shaking. We use the empirical Green’s function (EGF) method to determine S‐wave corner frequencies and stress drops of 87 earthquakes of moment magnitude (M) 2.3–4.4 in the WCSB. The EGF method is an effective technique to isolate earthquake source effects by dividing out the path and site components in the frequency domain, using a smaller collocated earthquake as an EGF. The corner frequency of the target event is determined for an assumed spectral ratio shape, from which the stress drop is computed.

Assuming a fixed velocity, we find that the average stress drop for induced earthquakes in the WCSB for small‐to‐moderate events is 7.5±0.5  MPa, with a total range from 0.2 to 370 MPa. However, because of the dependence of stress drop on model conventions and constants, we consider the absolute stress‐drop value meaningful only for comparison with other results using the same underlying models. By contrast, corner frequency is a less‐ambiguous variable with which to characterize the source spectrum. The range of corner frequencies obtained in this study for events of M 4.0±0.5 is 1.1–5.8 Hz.

Significant rupture directivity is observed for more than one‐third of the earthquakes, with station corner frequencies varying by about a factor of 4 with azimuth. This emphasizes the importance of having suitable station coverage to determine source parameters. We model directivity where evident using a Haskell source model and find that the rupture azimuths are primarily oriented approximately north–south throughout the region.
Attitudinal and Mathematical Assessments as Measures of Student Success in a College General Chemistry II Course
Authors: Kolopajlo Larry
Published: August 2019

This study reports results from administering unannounced attitudinal and mathematical assessments to 118 students, at the beginning of the term, in second-semester general chemistry classes (designed for science majors) at Eastern Michigan University. Testing was conducted during the 2010-2011 school year. The question to be answered was: which is more important in determining student course grades, attitudes toward chemistry and mathematics, or mathematical skill? The hypothesis was that attitudes and mathematical skill equally affect final course grade. A modified Wiebe instrument was selected to evaluate student attitudes toward chemistry and mathematics. To evaluate student mathematical skills, this study employed a mathematics assessment developed and performed at the University of Minnesota, and hence will be called the Minnesota Mathematics Assessment or MMA—a 20-question, multiple choice quiz designed for second-semester general chemistry students. Results were inter-correlated to determine what factors influenced student success. This study found a strong correlation between mathematics attitudes and chemistry attitudes, with a Pearson product-moment correlation coefficient (r) of 0.50. Between course grade vs. either chemical attitudes or mathematics attitudes, the r values were 0.25 and 0.23 respectively, showing weak correlations. The correlation of course grade versus total MMA score gave an r value of 0.35, a moderate correlation. Comparison of the current study's MMA results with those of a previous Minnesota study demonstrates that the MMA is reproducible. The correlation coefficient found for course grade vs. total MMA score was comparable to that found in the Minnesota study. Analysis of the 20-question MMA data resulted in a 10-question subgroup whose r = 0.41. Although some gender attitude differences were found, these did not correlate with course grade.

A Calculation of the Main Load Coefficient in Threaded Connections
Authors: Ryahovskiy O.A. , Syromyatnikov V.S.
Published: August 2019

Threaded connections of machine parts are widely used in various technical devices. The needs of modern machines stimulate the development of accurate methods for calculating and assembling threaded connections. The problem of calculating the strength of the connection is associated with determining the coefficient of the main load that affects the distribution of the external load between the bolt and the machine parts. One part of the load falls on the bolt; the other part unloads the connection elements. Until recently, when calculating the coefficient of the main load, approximations or recommendations to take its value in the range of 0.2–0.3 have been used. This paper refines the calculations and presents specific mathematical expressions for a computer program developed for calculating the coefficient of the main load. The calculation results show that the value of coefficient of the main load varies over a wide range depending on the bolt diameter, thickness, material of the parts, etc. An analysis of the results of programming and the construction of the regression dependence of the coefficient of the main load on the thickness of the connection for a given series of standard bolts is carried out using the statistical package Statgraphic Plus. Regression simplifies the calculation of the coefficient of the main load for any thickness of parts with a slight decrease in accuracy.

C/EBP-β and SIRT1 regulate IL-18 expression in the proliferative phase endometrium of patients with polycystic ovary syndrome (PCOS)
Authors: Long Xiaoyu , Zhu Xiaohui , Li Rong , Yang Yan , Qiao Jie
Published: August 2019

Background：Previous studies have shown that patients with polycystic ovary syndrome present with low-grade chronic inflammation. Our previous studies have confirmed that IL-18 is highly expressed in the serum and endometrium of patients with polycystic ovary syndrome. However, the mechanism of IL-18 elevation remains unclear. Therefore, this study aims to explore the signaling pathways that lead to the up-regulation of IL-18 in endometrium of PCOS patients. We predicted that C/EBP-β might be a transcription factor of IL-18 by using TF-Search tool, and deacetylase SIRT1 might be involved in its regulation.
Method：SIRT1 and C/EBP-β in proliferative endometrium of PCOS patients and control group by immunohistochemical method.The expression was localized. The genes and proteins of SIRT1 and C/EBP-β in endometrium of PCOS and control group were detected by real-time quantitative PCR and Western Blot respectively. The interaction between C/EBP-β and IL-18 was verified by double luciferase assay.
Result(s): The gene and protein levels of SIRT1 and C/EBP-β in proliferative endometrium of PCOS patients were significantly higher than those of the control group. Immunohistochemical experiments confirmed that SIRT1 was mainly expressed in endometrial nucleus, while C/EBP-β was mainly expressed in endometrial nucleus and cytoplasm. The interaction between C/EBP-β and IL-18 was confirmed by double luciferase assay.
Conclusion: SIRT1 and C/EBP-β are highly expressed in endometrium of PCOS patients, and may play a role in the regulation of IL-18.

Objective: This study aimed to explore whether the polymorphisms of CYP4F2 and CYP3A5 are correlated to the risk of lung cancer development. Methods: A case-control study was conducted among 510 patients with pathologically confirmed lung cancer as the case group and 504 healthy individuals as the control group. Four single nucleotide polymorphisms (SNPs) of the CYP4F2 and CYP3A5 genes were genotyped and their correlations with the risk for lung cancer were examined using χ2 test and logistic regression analysis. Results: Stratified analysis found that the rs3093105 and rs3093106 locus of CYP4F2 gene were significantly associated with lower risk of lung cancer (P=0.012, OR=0.64, 95%CI: 0.45-0.91). The correlation was related to patients’ age and sex and pathological type of lung cancer. Similarly, the rs10242455 loci of CYP3A5 gene showed a statistical significance between the case group and the control group (P=0.018, OR=0.71, 95%CI: 0.53-0.94), which also was associated with reduced risk of squamous cell lung cancer in the dominant and additive models (Dominant: OR=0.66, 95%CI: 0.46-0.94, P=0.021; Additive: OR= 0.71, 95%CI: 0.53-0.95, P=0.023). Conclusion: CYP4F2 and CYP3A5 gene polymorphisms are associated with the reduced risk of non-small cell lung cancer (NSCLC), and its correlation is related to patients’ age and sex and pathological type of lung cancer.

Background
Brazil and Mexico are the most populous countries in Latin America. Diabetes is a global growing problem. Although there are laws in the constitutions of both countries, Mexico and Brazil, regarding ensuring access to health, emphasizing the issue of diabetes, both populations are affected for this disease from different perspectives. The objective of this study was comparing the results of the National Health Survey “PNS” in Brazil and the National Survey Health and Nutrition “ENSANUT” in Mexico regarding prevalence, complications and healthcare issues of diabetes in both countries.Methods

A cross-sectional study was conducted with data from the National Health Survey (PNS) in Brazil, and the National Survey of Health and Nutrition (ENSANUT) in Mexico. The variables used in the PNS were taken from module P - Lifestyles and the Q module - Chronic Diseases The corresponding variables were searched in ENSANUT, module III - Diabetes Mellitus and module XIII - Risk Factors. The odds ratio for having any diabetes complication was calculated for all variables which were significant (p<0.05) in the descriptive analyses in two logistic regression models: simple models, with a regression performed with each variable separated and an adjusted model with all variables included.Results

The prevalence of diabetic was 6.8% in Brazil and 9.4% in Mexico. There were significant differences between age and time with diabetes between both countries. The odds of a Mexican comparing to a Brazilian diabetic patient of having a complication was 2.01 in the simple logistic regression model and 3.04 in the adjusted model (p<0.0001). Loss vision was the most frequent complication. Protector factors were physical exercise and drinking alcohol less than monthly.Conclusions

Diabetes complications are important health problems in Brazil and Mexico. National health surveys add significant information about the impact of diabetes in these Latin American populations. This comparison of data could provide available information to guide national policies and program decisions in both countries.
Thinking outside the (dosette) box: Professional support for medicines management at home for patients approaching the end of life. A qualitative study

Published: August 2019

Background: The management of medicines towards the end of life can place increasing burdens and responsibilities on patients and families. This has received little attention yet it can be a source of great difficulty and distress patients and families. Dose administration aids can be useful for some patients but there is no evidence for their wide spread use or the implications for their use as patients become increasing unwell.
Aim: To explore how healthcare professionals describe the support they provide for patients to manage medications at home at end of life.
Methods: Qualitative interview study with thematic analysis. Participants were a purposive sample of 40 community healthcare professionals (including GPs, pharmacists, and specialist palliative care and community nurses) from across two English counties.
Results: Healthcare professionals reported a variety of ways in which they tried to support patients to take medications as prescribed. While dose administration aids were useful for some they posed a number of practical difficulties. Other strategies described included: rationalising the number of medications; providing different formulations; explaining what medications were for and how best to take them; providing and supporting ways to record medication taking; and ways of balancing restricted access to controlled drugs and appropriate pain management for patients in the context of substance misuse and memory loss.
Conclusions: The burdens and responsibilities of managing medicines at home for patients approaching the end of life has not been widely recognised or understood. This paper considers some of the strategies reported by professionals in the study, and points to the great potential for a more widely proactive stance in supporting patients and family carers to understand and take their medicines effectively. By adopting tailored, and sometimes, ‘outside the box’ thinking professionals can identify immediate, simple solutions to the problems patients and families experience with managing medicines.

Abstract
Background: Alfalfa ( Medicago sativa ) is a perennial forage crop widely cultivated in northern China. The root crown of alfalfa is an important storage organ in the process of wintering, and it is closely related to the winter hardiness of alfalfa. At present, the specific molecular mechanism of response to winter hardiness in alfalfa root crown is unclear. The transcriptome database created by RNA sequencing (RNA-seq) is widely used to identify the critical genes related to winter hardiness.
Results: The transcriptomes of alfalfa varieties, such as “Lomgmu 806” (with high winter survival rate) and “Sardi” (with low winter survival rate) have been sequenced in the study. Among the identified 57,712 unigenes, 2,299 differentially expressed genes (DEGs) were up-regulated, and 2,143 unigenes were down-regulated in the Lomgmu 806 vs Sardi root crown. The KEGG pathway annotations showed that 1,159 unigenes were mainly annotated to 116 pathways. Seven DEGs belonging to “plant hormone signaling transduction”, “peroxidase” pathway and transcription factors family (MYB, B3, AP2/ERF, WRKY) genes involved in alfalfa winter hardiness. Among them, the expression patterns of seven DEGs were verified by real-time quantitative PCR (RT-qPCR) analyses, which verified the reliable results of transcriptome sequencing analyses.
Conclusions: RNA-Seq was used to discover genes associated with the wintering differences between alfalfa varieties. The transcriptome data showed that the gene regulation response of alfalfa to low temperature stress, which provides a valuable resource for further identification and functional analysis of candidate genes for winter hardiness of alfalfa. In addition, these data provide references for future study of genetic breeding and winter hardiness in alfalfa.
Low adaptive potential for tolerance to ethynylestradiol, but also low toxicity, in a grayling population (Thymallus thymallus)

The presence of a novel pollutant can induce rapid evolution if there is additive genetic variance for the tolerance to the stressor. Continuous selection over some generations can then reduce the toxicity of the pollutant but also deplete the additive genetic variance for the tolerance and thereby slow down adaptation. One common pollutant that has been ecologically relevant for some time is 17alpha-ethynyestradiol (EE2), a synthetic compound of oral contraceptives since their market launch in the 1960s. EE2 is typically found in higher concentrations in rivers than in lakes. Recent experimental work revealed significant genetic variance for the tolerance to EE2 in two lake-spawning salmonid species but no such variation in river-spawning brown trout. We used another river-spawning salmonid, the European grayling Thymallus thymallus, to study the toxicity of an ecologically relevant concentration of EE2. We also used a full-factorial in vitro breeding design and singly rearing of 1,555 embryos and larvae of 40 sib groups to test whether there is additive genetic variance for the tolerance to this pollutant. We found that exposure to EE2 reduced larval growth after hatching, but contrary to what has been found in the other salmonids, there were no significant effects of EE2 on embryo growth and survival. We found additive genetic variance for embryo viability, i.e. heritability for fitness. However, there was no significant additive variance for the tolerance to EE2. Our findings support the hypothesis that continuous selection has reduced the toxicity of EE2 and depleted genetic variance for tolerance to this synthetic stressor.
