При цьому забезпечується вибір будь-якої довільної тривалості сигналу.
First record of piscivory in the Tropical Kingbird (Tyrannus melancholicus)
Authors: González-Oreja José Antonio , Jiménez-Moreno Francisco Javier
Published: August 2018

Tyrant flycatchers (i.e., Tyrannidae) are primarily insectivores, but they can supplement their diet with spiders, fruits, or small vertebrates. Kingbirds are among the most specialized predators in this family, since they prey almost exclusively on flying insects. We document a Tropical Kingbird (Tyrannus melancholicus) capturing and eating a small fish (Poeciliopsis gracilis) in one of the bodies of water of the main campus of the Benemérita Universidad Autónoma de Puebla, in Puebla, Mexico. Although it is known that the Grey Kingbird (T. dominicensis) and the Eastern Kingbird (T. tyrannus) can prey opportunistically on fish, this is the first time fish-eating has been reported for the Tropical Kingbird.

Published: August 2018

El pseudofruto de marañón (Anacardium occidentale L.) es rico en composición nutrimental principalmente en ácido ascórbico, sin embargo su sabor astringente limita su aprovechamiento y consumo. La implementación de un método que disminuya esta astringencia permitiría su uso en la industria de los alimentos. El objetivo de este trabajo fue reducir la astringencia del pseudofruto de marañón evaluando el efecto de la concentración de gelatina y el tiempo de inmersión mediante un diseño experimental 32. Los resultados mostraron que la concentración de la gelatina tuvo un efecto significativo sobre el contenido de polifenoles totales. En la muestra control se redujo de 227.92 a 63.04 mg de ácido gálico equivalente/g de muestra cuando la concentración de la solución de gelatina fue de 1.5% y el tiempo de inmersión fue de 30 min. Los resultados permitieron concluir que la astringencia del pseudofruto de marañón puede ser reducida hasta un 72% y así tener mayor potencial de aplicación en la industria de los alimentos.

La creciente necesidad de vigilancia de las enfermedades infecciosas re-emergentes hace necesario la aplicación de métodos moleculares de caracterización como la Electroforesis en Gel de Campos Pulsados-PFGE. En la primera colecta, el análisis de macrorrestricción de S. aureus revela una frecuencia media (0.54) del pulsotipo II, en comparación a la segunda colecta donde se observa una mayor heterogeneidad genética. S. enterica presentó algunos pulsotipos idénticos y otros pulsotipos presentaron una diversidad genética
(ID=0.95), lo que nos sugiere, que no existe una relación epidemiológica con pulsotipos o serotipos particulares. Además, este estudio nos ayudara a crear nuestra base de datos de acuerdo a la PulseNet International del Centro de Control y Prevención de Enfermedades (CDC, USA)

Authors: Soto-Ochoa Lucero , Yáñez-Fernández Jorge
Published: August 2018

El uso de nuevos materiales para generar películas comestible ha crecido en los últimos años, pero estos nuevos materiales deben tener buenas propiedades de barrera y aceptables características mecánicas flexibles y una estructura elástica) para facilitar su aplicación. En la industria de empaques para alimentos las propiedades de barrera y mecánicas son los principales criterios de selección de estos. Por lo tanto, el objetivo de este trabajo fue estudiar los efectos de la composición sobre las propiedades de dureza y módulo elástico utilizando nanoindentación y microscopía de fuerza atómica. Un diseño experimental BoxBehnken de tres factores en tres niveles fue empleado para evaluar el efecto de almidón de plátano- goma gelana (0.25 - 0.75%) y concentración de glicerol (1- 3%) en las propiedades mecánicas. Los valores de rugosidad fueron de entre 35.18 y 120.8 nm y se encontró una dureza entre 0.8979 y 3.0777 MPa. El módulo elástico fue 0.0473 a 0.2687 GPa, estos valores sugieren la formación de películas comestibles suaves y flexibles a partir de
mezclas de almidón de plátano y goma gelana. Las propiedades de dureza y el modulo elástico de las películas comestibles de almidón de plátano- goma gelana fueron influidas por la concentración de glicerol; esta concentración fue inversamente proporcional a la dureza y el módulo elástico y los valores de rugosidad más bajos se obtuvieron con 0,5% de goma gelana, 0,5% de almidón y 2% de glicerol.

Cutinase is a very versatile enzyme due to the wide range of substrates that it can use. It has application in several biotechnological areas, acting as biocatalysts in the food industry, in detergents as well as in biodegradation of polymers and other toxic substances. In this research, glucose consumption, protein content, biomass and cutinase production by Fusarium culmorum were evaluated. Cutinolitic activity was observed using gel zymography. This fungus was grown on culture media containing glucose and different
concentrations of apple cutin (0, 1, 3 and 10 g/L) in solid-state fermentation. F. culmorum showed the highest production of biomass, protein and cutinase in medium supplemented with 10 g of cutin/L. Glucose uptake was inversely proportional to the cutin concentration. Medium lacking cutin showed the fastest glucose consumption. Heavily stained bands were observed in the gel with increasing concentrations of cutin after 72 h, showing a molecular weight of 50 kDa. These results shown that apple cutin induced cutinase production and was also used as carbon source. It was also observed that glucose did not act as a repressor of cutinase production.

NEOMODERNISM: TOWARDS A PARADIGM SHIFT IN MARKETING
Authors: TOPTAŞ Metin
Published: August 2018

The purpose of this paper was to address the paradigm shift in the philosophy of marketing science. This shift from modernism to postmodernism and now to neomodernism has been providing new perspectives in terms of the generation of knowledge related to marketing theory and practice as well as marketing research. Neomodernism reflects a combination of commonly appreciated facets of the previous paradigms (e.g. Modernism and Postmodernism), and thus presents a more mature and comprehensive perspective. In the paper, first, the emergence of Neomodernism was depicted in a historical point of view, and second, its possible implications for the certain aspects of marketing research, theory and practice were discussed.
A química sob(re) o corpo em Dalí e em Rabarama
Authors: Eichler Tatiana Zarichta Nichele , Eichler Marcelo Leandro
Published: August 2018

A química é a ciência que estuda a matéria e suas transformações. Por essa definição, o corpo também é domínio da química, material, orgânica, descritiva, explícita. Porém, compreende-se que a redução do corpo apenas à sua corporeidade achata a riqueza de sua complexidade. O corpo é, também, imagem e representação. Os químicos reconhecem que a representação é uma transformação simbólica da realidade. Neste ensaio, busca-se enfatizar alguns aspectos culturais das ciências químicas que são incorporados, imaginados e representados nas artes plásticas. A química sob o corpo é substrato para as imaginações e pinturas de desmaterialização de Salvador Dalí. A química sobre o corpo, na pele faz parte das palpitações, dos latejos em representações esculturais, de Paola Epifani, codinome Rabarama.

Published: August 2018

Objective: The objective of this study was to evaluate preliminary clinical and radiographic outcomes of a case series of patients with ankle osteoarthritis undergoing anterior tibiotalar arthrodesis using anterior plate and cannulated screws as a form of fixation. Methods: We retrospectively assessed the clinical and radiographic outcomes of eight cases treated with this technique in our service between 2014 and 2017, using the American Orthopedic Foot and Ankle Score (AOFAS) questionnaire and radiographic evaluation in two orthogonal views with ankle weight bearing, evaluated at one year after surgery. Results: We obtained AOFAS scores between 38 and 92 in the late postoperative period and a consolidation rate of 87.5% (seven cases). There was consolidation failure in one case, which resulted in plate loosening and the need for reoperation. Only one of the patients presented superficial surgical wound complication, treated only with serial dressings. There were no neurovascular complications. Conclusion: The present study obtained adequate preliminary outcomes with the use of the demonstrated technique, indicating a possible advantage of the same in relation to conventional techniques and the possibility of using lower-cost surgical materials. Level of Evidence IV; Therapeutic Studies; Cases Series.

Published: August 2018

Objective: To analyse the rate of unsatisfactory reduction in syndesmosis injuries by means of a postoperative tomographic study. Methods: This was a prospective study conducted from March to December 2017. Thirty patients with syndesmosis injury were selected, and ankle tomography was performed during the first postoperative period. A form developed for the study was used to collect demographic data (sex and age in years) and postoperative data (operated side, Weber classification, computed tomography results and need for surgical reoperation). The images were evaluated using tomographic criteria. The intraoperative analysis was performed through radioscopy and by direct visualization of the syndesmosis. Results: The majority of the patients were male (56.7%), ranging in age from 17 to 51 years; 53.3% of the patients were operated on the left side; 66.7% were classified as type C; and 66.7% did not undergo reoperation. Regarding the rate of unsatisfactory syndesmosis reduction, it was foundthat 25.9% of the analyses of the established variables presented unsatisfactory results. It was observed that 74.1% of the criteria presented satisfactory results; however, criterion B presented a significant rate (37%) of unsatisfactory results. Conclusion: Based on the computed tomographic scans, there was a high percentage of unsatisfactory reductions in syndesmosis injuries. Thus, it was concluded that, even using the correct fixation techniques and adequate intraoperative scopic monitoring, distal tibiofibular joint incongruence can still be observed when investigated using postoperative tomography.

Published: August 2018

Objective: To measure and evaluate the distance from the medial plantar nerve (MPN) to six predetermined anatomical landmarks, identifying 12 distances, and establish a correlation with the trajectory of the flexor hallucis longus (FHL) tendon, especially the knot of Henry, and the location of the bifurcation of the posterior tibial nerve (PTN) relative to the tarsal tunnel. Methods: A descriptive and quantitative study was conducted in which 15 adult feet (six right and nine left) from cadavers were dissected, and the anatomical relationship between the MPN and predetermined structures was evaluated. The distance from the medial border of the medial malleolus to the inferior calcaneal tuberosity [defined as a fixed reference (FR)] was measured to compensate for variability in foot size. Results: The results indicated that the bifurcation of the PTN was proximal to the tarsal tunnel in 11 feet (73.3%), within the tunnel in three feet (20%), and distal to the tunnel in one foot (6.66%). A statistically significant (p=0.035) association was found between the FR and the distance from the superior calcaneal tuberosity to the MPN, a strong correlation (p=0.004) was found between the FR and the distance from the inferior calcaneal tuberosity to the MPN, and a significant association (p=0.013) was found between the FR and the distance from the medial calcaneal tuberosity to the knot of Henry. Conclusion: Some anatomical structures, especially the knot of Henry, have a strong correlation with the MPN and should be considered by surgeons who intend to approach the FHL in the plantar region. Bifurcation of the PTN proximal to the tarsal tunnel was the most common presentation.Level of Evidence V; Expert opinion.

Fruit suitability of apple cultivars of new generation of VNIISPK breeding, which have immunity to scab (Vf, Vm), triploidy (3x), and columnarity (Co) as well as combine scab immunity and columnarity (Vf + Co), scab immunity and triploidy (Vf + 3x) in one genome, was studied for the purpose of juice production. The technological estimation was done according to the following indicators: juice output, contents of soluble dry substances, sugars, organic acids, P-active compounds in juice and organoleptic qualities of juice. The new cultivars showed a high level of the technological indicators important for juice production. This makes them promising in the production of natural juice directly pressed for consumption and for further concentration. Apple cultivars, such as Bolotovskoye, Osipovskoye, Spasskoye, Priokskoye and Bezhin Lug, are suitable for the production of baby food since the juice of these cultivars meet the requirements TR № 178-FZ in the contents of soluble dry substances and titrate acids for baby food. The technology development of innovational cultivars cultivation in raw orchards could significantly allow solving the problem of the shortage of raw materials in the national juice industry.

Authors: Zubkova M. I.
Published: August 2018

The aim of this study was to determine the biological productivity, actual yield and taste characteristics of introduced strawberry cultivars in conditions of the Orel region and to select promising genotypes for commercial use and breeding. The studies were carried out in 2016-2017 in the fields of the Russian Research Institute for Fruit Crop Breeding in the Orel region. 8 Russian strawberry cultivars and 18 foreign cultivars were studied. Strawberry cultivars admitted for use in the Central-Chernozem region, i.e. Rubinovy Kulon (early ripening), Urozhainaya TzGL (average ripening) and Zenga Zengana (late ripening), were taken as control cultivars. The cultivars were placed in three repetitions in the amount of 10 plants in each repetition. The soil of the plots was dark-grey forest. Previously the field was planted with mustard. The location of the plots was randomized. Drip irrigation was used. The spacing of planting was 0.2 m X 1.0 m. The biological productivity was studied according to three indications: the amount of flower buds per plant, the amount of flowers per plant and the average weight of berries per plant. Clary, Alba, Solovushka, Asia, Sonata, Berginya, Molling Pandora, Alfa and Malvina had the greatest average weight of berries. Alba, Solovushka, Sara, Asia, Sonata and Bereginya had maximal indications of biological productivity. The greatest actual yield was observed in Vima Zanta, Solovushka, Sara and Berginya. Rosinka and Urozhainaya TzGL were the best ones in berry taste; Alba and Bereginya were the best ones in berry appearance; Sara and Antea had the most fragrant berries. Alba, Solovushka, Asia, Tzaritza, Bereginya and Sonata are the most promising strawberry cultivars according to the complex of the indications for growing in the Central -Chernozem region.
Perceptions and Preferences of Urban Greenspaces: A Literature Review and Framework for Policy and Practice
Authors: Mahmoudi Farahani Leila , Maller Cecily Jane
Published: August 2018

The ever-increasing process of urbanisation across the globe has major implications for the environment, biodiversity and health and wellbeing of urbanites. Urban greenspaces are considered a promising planning tool in tackling some of the problems associated with urbanisation such as pollution and urban heat island effects. It is, therefore, important to understand what  encourages the extent to which urban dwellers interact with or use greenspaces. Perceptions and preferences are different ways of exploring how users interact with greenspace, but they are traditionally considered separately in extant research. The aim of this literature review is to synthesise the existing evidence for both perceptions of and preferences for greenspaces, highlighting crossovers and synergies between these two approaches. Drawing on a review of literature found in three online databases — EBSCOhost Web, Taylor and Francis Online and Elsevier —, the paper proposes a framework for understanding perceptions of and preferences for greenspaces which can assist policy makers and planners to develop and design greenspaces with higher efficiency and use or improve existing ones, ultimately improving the liveability of urban environments.

Published: August 2018

Abstract: this article attempts to identify the issues covered by the science of «psychology of Islam» in the Russian context. The institutionalization of science is based on a comparison of the subjects and content of the works of Russian, European and other foreign psychologists of religion. The main aspects of theoretical approaches and empirical research are identified as a basis for developing psychological support for Muslims. The article addresses the problem of demarcating the psychology of Islam and Islamic psychology. The main activities of the Association of psychological assistance to Muslims in Russia are reviewed.
Feasibility of parallel assessment of students, teachers and school curriculum based on long-term retention.
Authors: sitaramam vetury , Vetury-Iyer Pallavi
Published: August 2018

Assessment in schools is restricted to year-end or course-end tests that demand cramming which does not reflect true learning. The performance in these year-end examinations is skewed by socio-economic factors, besides the psychological stress induced and the resultant, unacceptable malpractices. Long term retention of school learning has not been recognized and developed into a viable alternative to assess what has been grasped by the student. We developed a quantitative design for a rapidly deployable test for long term retention as a viable alternative to assess true learning for the first time. While the data demonstrates drastic falling of retention with years of schooling towards more recent years, it has unique attributes depending on the subjects taught, independent of socioeconomic circumstances and gender, not apparent from the usual school tests. What has been learnt cannot be independent of what was taught and by whom and thus the test holds promise to assess the teachers and curriculum thereby completing the educational triad by the same method and at once. This feasibility study eschews external standards in assessment and quantitatively validates ‘in situ’ assessment of the educational triad of students, teachers and curriculum. This is in conformity with the long held, and yet never quantified, general view that what is learnt is not retained but what is retained over the entire schooling period is definitely learnt.
A New Approach to Keyboard Inputting Error Prevention and Increasing Inputting Productivity
Authors: Eigen Lewis D.
Published: August 2018

This article describes the initial concept and developments of a new approach to reducing the number of inputting errors that are made in working with computers and decreasing the time the inputter must spend correcting errors. The approach involves intercepting and correcting errors before they are designated as such by Spell Check and eliminating the need for the time and effort of Spell Check. The operating principles and concepts of this approach, called Super ErrorCorrect™, is described, along with a software suite, that enables the implementation and the testing of the approach. This paper reports on the changes and evolution that resulted from analysis and limited Beta Testing. The preliminary data shows that not only is the Super ErrorCorrect™ approach feasible, but substantial time is saved while error rates are reduced markedly. Some data also suggests that in addition to the time saved in not using Spell Check, there is a tendency for users to type faster as they do not get negative reinforcement when they type faster and make errors as the software fixes the error in real time. Researchers are invited to collaborate in further research and licenses to the technology and software are provided at no cost if research results will be publicly disclosed.
Assessing Phenotypic and Polygenic Models of ADHD to Identify Mechanisms of Risk for Longitudinal Trajectories of Externalizing Behaviors
Authors: Li James Janford
Published: August 2018

Background: Children with ADHD frequently engage in higher rates of externalizing behaviors in adulthood relative to children without. However, externalizing behaviors vary across development, and not all children with ADHD will go on to exhibit externalizing behaviors as adults. Furthermore, little is known about how this risk unfolds across development. Phenotypic and polygenic models of childhood ADHD were used to predict individual differences in adult externalizing trajectories. Supportive parenting, school connectedness, and peer closeness were then examined as causal mechanisms. Methods: Data were from the National Longitudinal Study of Adolescent to Adult Health (N=7,674). Externalizing behavior was measured using data from age 18-32 and modeled using latent class growth analysis. Child ADHD was measured using retrospective self-report (phenotypic model) and genome-wide polygenic risk scores (polygenic model). Multiple mediation models examined the direct and indirect effects of the phenotypic and polygenic models (separately) on externalizing trajectories through the effects of adolescent supportive parenting, school connectedness, and peer closeness.Results: Phenotypic and polygenic models of ADHD were associated with being in the High Decreasing (3.2% of sample) and Moderate (16.1%) adult externalizing trajectories, but not the severe Low Increasing trajectory (2.6%), relative to the Normal trajectory (78.2%). Associations between both models of ADHD on the High Decreasing and Moderate trajectories were mediated through the effects of school connectedness, but not supportive parenting or peer closeness. Conclusions: Findings shed light on how childhood ADHD affects downstream psychosocial processes that then predict specific externalizing outcomes in adulthood. They also reinforce the importance of fostering a strong school environment for adolescents with (and without) ADHD, as this context plays a critical role in shaping the development of externalizing behaviors in adulthood.
Consideration of Custom (ʿUrf) by the Izalah Organization in Gombe, Nigeria: A Critical Examination
Authors: Kumo Aishatu Abubakar , Shah Sayed Sikandar , Zakariyah Luqman
Published: August 2018

‘Urf in the Sharīʿah serves as an essential tool for dealing with mu‘ᾱmalāt aspects of Muslim life. The ‘urf rulings stipulated by the scholars determine its acceptability or otherwise. A certain ‘urf serves as a legal principle to conduct a transaction in social interaction. However, Jamᾱ’atu Izalatil bid’a wa Iqᾱmatis Sunnah (The Society for the Removal of Innovation and Establishment of the Sunnah) uses the term bid‘ah indiscriminately to include some customary practices in mu‘ᾱmalāt. This leads to a different perception of how people understand the word and its application, which gives a different dimension of interpretation on the Sharīʿah allowance of ‘urf usage. Thus, depicting ʿurf as bid‘ah complicates the ability to verify the crux of bid‘ah in matters pertaining to ‘ibᾱdah and mu‘āmalāt in their respective domains. The results of the qualitative research conducted in Gombe metropolis show the people’s understanding and utilization of the words to be synonymous. This is a result of the Izalah organization’s application of the two words (bidʿah and ʿurf) in dealing with mu‘āmalāt as well as ʿibᾱdah. Muslims misunderstood the utilization of these terms and therefore misapply some practical Sunnah in marriage celebrations, for example, as bidʿah. Therefore, there is need for the organization to educate Muslims on the validity of customary practices that do not contravene the teachings of Islam.
