Exercise Training as a Mediator for Enhancing Coronary Collateral Circulation: A Review of the Evidence
Authors: Nickolay Thomas , Nichols Simon , Ingle Lee , Hoye Angela
Published: August 2019

:

Coronary collateral vessels supply blood to areas of myocardium at risk after arterial occlusion.
Flow through these channels is driven by a pressure gradient between the donor and the
occluded artery. Concomitant with increased collateral flow is an increase in shear force, a potent
stimulus for collateral development (arteriogenesis). Arteriogenesis is self-limiting, often ceasing
prematurely when the pressure gradient is reduced by the expanding lumen of the collateral vessel.
After the collateral has reached its self-limited maximal conductance, the only way to drive further
increases is to re-establish the pressure gradient.
During exercise, the myocardial oxygen demand is increased, subsequently increasing coronary
flow. Therefore, exercise may represent a means of driving augmented arteriogenesis in patients
with stable coronary artery disease. Studies investigating the ability of exercise to drive collateral
development in humans are inconsistent. However, these inconsistencies may be due to the heterogeneity
of assessment methods used to quantify change. This article summarises current evidence
pertaining to the role of exercise in the development of coronary collaterals, highlighting areas of
future research.

Authors: Maleki Nayereh , Sadeghian Effat , Shamsaei Farshid , Tapak Lily , Ghaleiha Ali
Published: August 2019

Background:

Spouses of patients with bipolar disorder may experience a different quality
of life and burden than seen with major depressive disorder.

Objective:

This study was conducted to comparatively analyse spouse’s burden and quality of life in
major depressive and bipolar disorders.

Methods:

This cross-sectional study was conducted on 220 spouses of patients with major depressive
and bipolar disorders in the city of Hamadan in Iran, in 2018. Data collection tools included
Zarit Burden and QOL-BREF questionnaires. Data were analyzed by a t-test using SPSS -16.

Results:

The findings showed that 11.8% of spouses of patients with depression and 85.5% of
spouses of patients with bipolar disorder experienced severe burden (P < 0.001). The quality of life
of spouses of patients with bipolar disorder was lower than with depressive disorder (P < 0.05). In
both the groups, a negative correlation was found between burden and QOL.

Conclusion:

The spouses of patients with bipolar disorder experience more burden and lower quality
of life than depression. In both the groups, burden has a negative impact on the quality of life.
Professional help and supportive intervention can be provided to the spouses of patients with major
depressive and bipolar I disorders to reduce their burden, strengthen their coping skill and thus improve
their QOL.
Improved Algorithm of the Video Moving Object Detection Based on ViBE
Authors: Zhongsheng Wang , Zhichao Lian , Yubian Wang , Jianguo Wang
Published: August 2019

Background:

ViBE (Visual Background Extractor) is an algorithm with a variety of advantages
in video moving object detection which utilizes a pixel-level background modeling. However,
it is not suitable for distinguishing the scene of drastic change, adapts poorly to the sudden
change of the illumination and may lost the object easily, because this algorithm uses a fixed threshold
to distinguish the background from the foreground.

Methods:

In this paper, an improved ViBE algorithm is proposed, which an adaptive dynamic
threshold method is introduced for classification of the foreground and the background in the changing
scenes. When reconstructing the model it required for drastic change of illumination, Otsu algorithm
is used to judge the threshold and select the appropriate frame to complete the reconstruction
to achieve quick adapt to the light.

Results:

Experimental results show that the proposed algorithm has higher recall value, better precision
and F value comparing to the original algorithm. The improved algorithm has the highest classification
accuracy among other similar algorithms and therefore the improved algorithm significantly
improves the detection results.

Conclusion:

After analyzing the principle of ViBE algorithm, this paper proposed improvements to
it from two aspects to aim at its deficiency. Taking into account of the dynamic changes of different
environments, the change factor was proposed to measure the dynamic degree of background. According
to the value of the factor, adaptive clustering was obtained and clustering threshold was updated to
improve the adaptability of the algorithm to the dynamic environments. The improved ViBE algorithm
can find the appropriate frame to reconstruct model structure in the case of abrupt light change, which
can quickly adapt itself to the light change and be more accurate in the object detection.

The results of experiments with the initiator of lithium and graphite, the mass of which was ~ 10% by weight of the projectile, are presented. Such initiators create plasma with a high sound velocity value and provide the initial projectile speed of ~0.5 km/s. The drop-like damages on the insulating wall of the launcher barrel are described. There is a link between the appearance of these damages and sudden braking of the plasma piston. A hypothesis is discussed that relates the occurrence of these damages to the resonant deformation of the channel under the action of a moving high-pressure front. It is shown that the hypothesis of the resonant deformation of the barrel at a qualitative level explains the known features of the launcher operation.

Non -verbal Politeness in English Etiquette Books and Prophetic Sunnah
Authors: Ahmed Muhammed Badeaꞌ , Ghaffori Ayhan Abdul Mun’im
Published: August 2019

Non-verbal politeness is an important feature that characterizes human communication. Through this type of communication one can find a high degree of sophistication and civility in the language of the body, as this type of language can say and express more than language itself. Thus, there should be a use of certain cues to express courtesy and politeness such as: facial expression, eye contact, gestures, posture, and proxemics. This study aims at explaining the role of the different forms of non-verbal politeness in Prophetic Sunnah and the British etiquette books in particular, then analyzing these texts within the eclectic model of this study, highlighting points of similarity and difference between the two cultures. It is hypothesized that the two cultures display different orientations to the ways of acting non-verbally. The model adopted in this study is Martin and Nakayama (2010) with reference to Andersen (1999), Poyatos (2002) and Koneru (2008) within the framework of Brown and Levinson’s model of politeness and in accordance with Hofstede's (2001) cultural values. The main conclusions of the current study are: (i) Non-verbal politeness almost goes hand in hand with other forms of verbal politeness. (ii) Non-verbal politeness is employed differently in both the Prophetic Sunnah and English etiquette books. (iii) Islamic Sunnah as compared to English etiquette books concentrates on cordiality and maintaining positive politeness among Muslims, while English etiquette texts emphasize individuality and negative politeness.
Emotional Metaphors in the Glorious Quran with Reference to Their Realizations in English
Authors: Hammood Sufyan Mahdi , Khalid Raneen Waleed
Published: August 2019

Metaphors are an essential part of human experience. Each person depends on their everyday experience in relation to the linguistic system so that an image is created in their mind. The purpose of this study is to investigate metaphors of emotions in the Glorious Quran from a cognitive perspective. Throughout conceptual metaphors, readers structure and understand the abstract concepts in terms of more concrete ones. They perform more significant functions when they are used in the language of the Glorious Qur’an which has intellectual, psychological and aesthetical significances. Using a three-dimensional model to analyze the data which consists of the following; First, Lakoff and Johnson's Metaphors We Live By in its two editions (1980) and (2003). Second, Arabic data depends on Al-Hayani (Metaphor in The Glorious Qur'an: Its Patterns and Rhetorical Meanings) (2016) who classifies meanings into three types; intellectual, psychological and aesthetic. Third, Newmarks' (1988) model of translation is also adopted. In this study, six Ayahs contain different types of emotions from the Glorious Quran are analyzed. The miraculous nature of the Glorious Qur'an is represented by its language which, unlike ordinary language, underlies variety of meanings. As a result, three translations are chosen; Pickhtall (1930), Ali (1987) and Hilali and Khan (1996). This study concludes that metaphors of emotions have a decisive role in our daily experience.
Mindfulness-Based Cognitive Therapy for Improving Subjective Well-Being Among Healthy Individuals: Protocol for a Randomized Controlled Trial (Preprint)
Authors: Sado Mitsuhiro , Kosugi Teppei , Ninomiya Akira , Nagaoka Maki , Park Sunre , Fujisawa Daisuke , Shirahase Joichiro , Mimura Masaru
Published: August 2019

BACKGROUND

Previous studies have indicated that higher subjective well-being works as a protective factor for health. Some studies have already shown the effects of mindfulness-based interventions on improving subjective well-being. However, these studies targeted specific populations rather than the general public. Furthermore, they assessed either life evaluation or affective aspects of subjective well-being rather than the concept as a whole, including the eudemonic aspect of well-being.

OBJECTIVE

This study aims to investigate the effectiveness and cost-effectiveness of mindfulness-based cognitive therapy (MBCT) for improving the wholistic aspects of subjective well-being in healthy individuals.

METHODS

This study was an 8-week, randomized, parallel-group, superiority trial with a 2-month follow-up. Healthy individuals aged 20-65 years with scores lower than 25 on the Satisfaction With Life Scale (SWLS) were eligible to participate and randomly allocated to the MBCT group or the wait-list control group. The intervention program was developed by modifying an MBCT program to improve the well-being of a nonclinical population. The primary outcome was the difference between the two groups in mean change scores from the baseline on the SWLS. The secondary outcomes included scores on the Flourishing Scale and the Scale of Positive and Negative Experience as well as the incremental cost-effectiveness ratio.

RESULTS

This study began recruiting participants in July 2018 and recruitment was completed at the end of September 2019. Data collection and dataset construction was completed by the end of March 2020.

CONCLUSIONS

This study is unique in that it investigates MBCT’s effects on the three different aspects of subjective well-being: life evaluation, affect, and eudemonia. It is limited, as the specific effect attributable to MBCT cannot be detected because of the lack of an active control group.

Mekanisme Fouling pada Membran Mikrofiltrasi Mode Aliran Searah dan Silang
Authors: Shalahuddin Iqbal , Wibisono Yusuf
Published: August 2019

A B S T R A C TMicrofiltration is a low pressure driven membrane process of about 1 bar trans-membrane pressure which is used frequently for separating dissolved particles within 0.1 to 10 μm size. Microfiltration membranes are utilized in water and wastewater treatment processes either during pretreatment, treatment, or post-treatment steps. Moreover in bioprocessing, microfiltration is used in upstream process for substrate sterilization or in downstream process for microbial suspension separation. Fouling is one major concern of membrane filtration processes, including microfiltration. In this article, the fouling mechanism on microfiltration membrane is explained based on the blocking model refer to cake filtration due to the complexity of fouling phenomena. Fouling mechanism on dead-end and cross-flow modes microfiltration are explained, and basically distinguished into four different mechanisms, i.e. complete blocking, standard blocking, intermediate blocking and cake filtration. The proposed models are based on constant pressure operation on the uniform membrane pores, both for dead-end and cross-flow modes. Cross-flow mode, however, is restricted on the beginning of filtration until critical flux condition is reached.Keywords: bioprocess; blocking model; cake filtration; fouling; microfiltration; wastewater A B S T R A KMembran mikrofiltrasi merupakan salah satu teknologi membran yang menggunakan tekanan rendah sekitar 1 bar sebagai gaya pendorong dan digunakan untuk proses pemisahan partikel terlarut yang berukuran antara 0,1 hingga 10 μm. Membran mikrofiltrasi banyak digunakan baik dalam proses pra-pengolahan, pengolahan, maupun pasca-pengolahan air dan air limbah. Pada bioproses, mikrofitrasi juga digunakan pada proses hulu untuk sterilisasi substrat atau pada proses hilir untuk pemisahan suspensi mikrob. Masalah yang paling utama dalam proses filtrasi membran adalah fouling. Dalam artikel ini, mekanisme terjadinya fouling pada membran mikrofiltrasi dijelaskan dengan menggunakan model pemblokiran yang mengacu pada filtrasi deposit partikel (cake) untuk menguraikan kerumitan fenomena fouling dalam mikrofiltrasi. Pada tulisan ini dijelaskan lebih rinci mengenai mekanisme fouling baik pada mikrofiltrasi searah (dead-end) maupun aliran silang (cross-flow). Mekanisme fouling pada proses mikrofiltrasi bisa dimodelkan dengan empat model yaitu pemblokiran pori, penyempitan pori, pemblokiran pori bersamaan dengan endapan permukaan dan formasi endapan permukaan. Mekanisme tersebut berlaku pada kondisi operasional bertekanan tetap dan ukuran pori yang seragam, baik pada aliran searah ataupun silang. Hanya saja, model mekanisme pada aliran silang hanya berlaku pada kondisi awal filtrasi hingga tercapai kondisi fluks kritis.Kata kunci: air limbah; bioproses; filtrasi cake; fouling; mikrofiltrasi; model pemblokiran
Portable Screen Time and Kindergarteners’ Attention with Content as a Potential Moderator
Authors: Vigil Kimberly B
Published: August 2019

Portable screens such as smart phones and tablets are a normal part of children’s everyday lives, yet excessive media use presents a multitude of health and developmental concerns. Specifically, the impact of portable screen time on children’s attention is unknown, and screen time could potentially result in negative outcomes including poor school readiness and social difficulties. The purpose of this study was to assess the relationship between portable screen time and kindergarteners’ attention (the first research question), and to investigate learning content as a potential moderator (the second research question). Data were collected using the Preschool and Kindergarten Behaviors Scale, 2nd Edition attention subscales and questionnaires on portable screen time and content, and analyzed via hierarchical multiple regression. Results included a significant relationship between screen time and attention, where, as screen time increased, attention decreased, and insignificant findings for a moderating relationship between screen time and content on attention. It was recommended that adults monitor children’s portable screen time to ensure attention is not compromised, and that screen time be utilized for educational purposes using quality programming. Recommendations for future research include studies which address portable screen time and learning content, structure/pacing, interactivity, and context of children’s screen time.
Grey zones of production: Discussing the technology of tools at the Lojanik quarry in west-central Serbia

Published: August 2019

Flaked stone artefacts found on the quarry Lojanik in west-central Serbia are good examples of how the function of non-diagnostic pieces could be determined through technological and use-wear analysis. In this study, we present the examples of surface clusters and artefacts from stratigraphic layers. Our attention is focused on the prevailing category of fragmented raw materials in the initial phase of knapping, preforms, debris, shattered pieces of anthropogenic origin and an immense number of artefacts and geofacts.

The study of mines and quarries, as well as distribution of the raw materials that come from the central Balkans is an understudied phenomenon. Flaked stone artefacts found on the outcrops of the Lojanik hilltop is a good example of how we can apply technological, petrological and use-wear analysis on this type of site. Keeping in mind the loose context of the finds, as well as the lack of any datable material, this issue has to be approached with a lot of caution, since the locality itself seems to show human presence during Palaeolithic, Neolithic and Chalcolithic. The main focus of the study was put on the prevailing categories linked to the initial extraction of raw material on the site, as well as initial steps of shaping the raw material into cores. Samples were collected from several outcrops and so-called workshops from two localities of the hilltop: Lojanik 1 and Lojanik 2. The focal points of interest are categories that include waste, shatter, technical or shaping flakes. Worked pieces of raw material are now in the central position, and the study of these pieces have opened new grounds for this and similar occurrences - the study of so-called “grey zones” of production.
La ética en la investigación cualitativa

Published: August 2019

Introducción.Abordar la investigación cualitativa y las implicaciones éticas que derivan de ella, nos lleva a desglosar cada componente para una mayor comprensión, por ello en este ensayo partiremos con un breve panorama de la ciencia, seguido de la investigación en su contexto general, para después abordar las características de la investigación cualitativa. Por supuesto los aspectos éticos, pero que necesariamente aplican en un método cualitativo. Desarrollo. Cabe mencionar que la investigación en general equipara muchos de sus aspectos éticos con la cualitativa, sin embargo, se le deben atribuir otros aspectos, en función de su metodología. Pare ello se analizan y discuten dos propuestas formuladas en otros estudios, que permitieron conjugar doce requisitos éticos indispensables al momento de aplicar investigación de tipo cualitativa. Conclusión. De no cumplir con la ética, sin duda la investigación puede resultar mal, durante su aplicación, con los involucrados o incluso ya puesta en demostración ser evidenciada con irregularidades que pongan en entredicho la credibilidad, profesionalismo y autenticidad del investigador.

Los niveles de lectura en los estudiantes de educación básica en Chile y en la Araucanía son aún deficientes. Asimismo, las prácticas docentes de lectura son poco diversas. El objetivo de la investigación fue analizar las concepciones sobre la lectura de profesores de la región de la Araucanía. El diseño fue descriptivo y cualitativo; los participantes fueron 20 docentes de 18 escuelas públicas de las comunas más pobladas, a quienes se les aplicaron entrevistas semiestructuradas, analizadas desde la fenomenografía. Se identificó que los docentes presentan concepciones predominantemente reproductivas y epistémicas con énfasis en uno de ambos perfiles, y que esta relación es definida por el propósito de lectura. Los docentes con tendencias más reproductivas manifiestan fines pragmáticos y estrategias apegadas al texto, mientras que los más epistémicos vinculan esta actividad con el placer y su identidad y son más inclusivos.

Published: August 2019

O cimento é largamente utilizado nas construções civis de grande e pequeno porte em todo o mundo e sua produção é responsável pela grande emissão de diversos poluentes para o meio ambiente devido a queima de combustíveis fósseis na etapa de aquecimento dos fornos. Desta forma, grandes potências mundiais vêm estudando alternativas para minimizar os impactos ao meio ambiente relacionados a essa poluição. Uma metodologia que vem sendo explorada é a substituição da utilização de combustíveis fósseis no aquecimento dos fornos por combustíveis renováveis, como o carvão vegetal e as biomassas que possuam características físico-químicas semelhantes à do coque e do carvão mineral. O presente trabalho objetiva avaliar alguns tipos de biomassa origem agrícola de diversos segmentos que possam ser utilizadas como combustível ou parte do mesmo na produção de cimento Portland. A avaliação foi realizada com base no poder calorífico de cada biomassa, comparando-o com o do carvão mineral utilizado em fornos, bem como através de uma análise econômica e logística do material renovável. A coleta de dados foi realizada por meio de pesquisa bibliográfica em dissertações e artigos publicados em revistas e convenções, resultando em projeções satisfatórias da utilização de biomassas.
On predicator rules and indexicality
Authors: Lion Clément
Published: August 2019

Argumentamos que ningún intento de reducir el significado a un conjunto sistemático de reglas, según el cual el papel de las expresiones lingüísticas debe definirse normativamente, puede abstraerse de un compuesto irreductiblemente decisional. Comparando el proyecto de Lorenzen de construir un lenguaje ortodoxo (Orthosprache) con el enfoque inferencialista de Brandom sobre el significado, distinguimos aquí dos formas de reconocer este hecho. Afirmaremos entonces que el enfoque de Lorenzen es más genuinamente constructivo, en la medida en que las elecciones se consideran características genuinas de las construcciones. Esto nos llevará a una nueva perspectiva de la relación entre el constructivismo dialógico y el intuicionismo de Brouwer. De esta manera, presentamos un argumento filosófico para la afirmación de que las reglas de interacción deben indexarse en relación a los jugadores y sus elecciones, al proporcionar bases deónticas a la semántica.
A influência do Tractatus no critério positivista de significado

Published: August 2019

Uma das motivações para as pesquisas realizadas pelos membros do Círculo de Viena a respeito dos fundamentos da linguagem científica se encontra na obra de Wittgenstein “Tractatus Logico-Philophicus”.Embora haja divergências sobre a legitimidade dessa influência, o livro foi, com efeito, tomado como motivação teórica para a estruturação da linguagem científica, desenvolvida pelos empiristas lógicos. Este artigo apresenta as teorias desenvolvidas pelos membros do Círculo de Viena ressaltando os elementos presentes no Tractatusque foram tomados, em grande parte, como influência sobre o “critério de significado” de uma proposição filosófica adotado pelos empiristas lógicos na tentativa de se estabelecer uma fundamentação para o conhecimento.

Published: August 2019

O mercado no qual se insere o setor têxtil demanda um alto nível de competitividade e atualização das empresas, ao mesmo tempo em que responde a diversos normativos ambientais devido a seu potencial de geração de externalidades negativas. Estas questões tornam clara a necessidade de uma gestão estratégica que compatibilize a busca pelos resultados com o respeito às questões sociais e aos recursos naturais. Um dos grandes polos de produção e comercialização de produtos têxteis no Brasil localiza-se no Agreste pernambucano, com foco na produção de jeans. Há diversos municípios que têm sua economia positivamente influenciada por este mercado. Há também, contudo, diversos problemas sociais e ambientais relacionados ao alto consumo de água no processo produtivo, ao descarte inadequado dos efluentes nos cursos d’água e às condições insalubres de trabalho às quais são submetidos os trabalhadores. Diante desta problemática, este artigo tem como objetivo a definição do grau de maturidade da gestão ambiental de empresas do setor têxtil por meio da aplicação do Índice de Desempenho da Gestão Ambiental (IDGA) – indicador ambiental desenvolvido no âmbito do Programa de Desenvolvimento e Meio Ambiente da Universidade Federal de Pernambuco (PRODEMA/UFPE). O conhecimento do IDGA das organizações serve como um ponto de partida para a identificação de pontos de melhoria em aspectos socioambientais. A metodologia do IDGA foi aplicada em duas lavanderias têxteis do município de Toritama, Agreste Pernambucano, e os resultados identificados foram de nível médio nos dois casos, respeitadas as particularidades quanto ao desenvolvimento de cada um dos aspectos analisados.

Published: August 2019

A degradação do solo pode ser evitada a partir de estudos que indiquem o potencial de uso da terra. O objetivo deste trabalho foi avaliar a capacidade de uso das terras e reconhecer as áreas prioritárias para preservação na bacia hidrográfica do Ribeirão São Lourenço em Ituiutaba/MG. Por meio de técnicas de geoprocessamento os dados foram compilados para classificação das terras no sistema de capacidade de uso. Em torno de 88,82% da área da bacia está apta à agricultura (classes II e III). Na classe IV o uso agrícola é mais restrito, sendo indicado o cultivo perene. As áreas inaptas à agricultura (classes VII e VIII) possuem potencial prioritário para preservação, devido às condições do solo e declividade. A classificação das terras fornece subsídios importantes nos processos de planejamento ambiental, indicando os usos dentro do seu potencial evitando a sub ou sobreutilização da terra.

Published: August 2019

OBJECTIVE

Most previous studies on cardiovascular health (CVH) and incident type 2 diabetes (T2D) have used a single measure of CVH, and none have investigated the association with impaired fasting glucose (IFG). We examined the association between changes in CVH and incident T2D and IFG.

RESEARCH DESIGN AND METHODS

Within the Whitehall II study, CVH was examined every 5 years from 1991/93 until 2015/16. Subjects with 0–2, 3–4, and 5–6 ideal metrics of CVH from the American Heart Association were categorized as having low, moderate, or high CVH, respectively.

RESULTS

There were 6,234 participants (mean age 49.8 ± 6.0 years, 70% male) without prior cardiovascular disease and T2D, including 5,015 who were additionally free from IFG at baseline. Over a median follow-up of 24.8 (interquartile range 24.0–25.2) years, 895 and 1,703 incident cases of T2D and IFG occurred, respectively. Change in CVH between 1991/93 and 2002/04 was calculated among 4,464 participants free from CVD and T2D and among 2,795 participants additionally free from IFG. In multivariate analysis, compared with those with stable low CVH, risk of T2D was lower in those with initially high CVH (hazard ratio [HR] 0.21; 95% CI 0.09, 0.51), those who had persistently moderate CVH or changed from moderate to high CVH (moderate-moderate/high; HR 0.53; 95% CI 0.41, 0.69), low-moderate/high (HR 0.62; 95% CI 0.45, 0.86), and moderate-low (HR 0.74; 95% CI 0.56, 0.98). Results were similar for IFG, but the effect sizes were smaller.

CONCLUSIONS

Compared with stable low CVH, other patterns of change in CVH were associated with lower risk of T2D and IFG.

The work studied the relationship between polar jet stream core speed at 300 hPa level and the surface low pressure system on winter seasons during years from 2014 to 2016. Februaries were chosen from winter seasons which the polar jet stream passes with high frequencies over the area of study. The study presented that the structure of polar jet was almost continuous jet-type structure that the jet core was easy to recognize and it had indirect relationship with the low pressure systems at surface. the Pearson's (R) statistical test used to show the strength of that relationship which accessible values were between (0.6 - 1) that presented the core speed values as a good element to derive equation connecting between the low pressure system value in (hPa) at surface and core speed value in (kt) at 300 hPa level . The simple linear regression technique is used to drive the equation that connects between the low pressure system and the jet core speed value which was (Low pressure center value (hPa) =1042.57 ̶ (0.307 × core speed (kt) )) . The equation was tested against some jet stream cases at 300 hPa that were the highest value of the jet core speed, the lowest and middle selected value which presented the percentage errors were between (0.03-0.09). the chart analyzing presented the lowest low pressure system center corresponded the highest the jet core speed values as shown in 11 Feb., 2015 at 00 UTC which the core speed was 150 (kt) corresponding the surface low pressure system which was 993 (hPa)

The Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) is a polyphagous insect pest of agriculturally important crops. The alkaline gut of this insect pest possesses diverse bacterial communities which may assist in digestive physiology. As part our investigations of understanding the role of gut bacterial communities in insect gut, here amylase producing competency of earlier identified H. armigera gut bacterial strain, i.e., Bacillus subtilis RTSBA6 6.00 is reported. Initial screening for amylase activity was assessed by starch agar plate. Upon 7% sodium dodecyl sulfate polyacrylamide gel electrophoresis amylase zymography, bacterial culture supernatant produced seven amylase bands on the gel. The observed molecular weights of amylases were 191.2 KDa, 158.0 KDa, 131.7 KDa, 54.0 KDa, 31.3 KDa, 67.2 KDa, and 44.6 KDa, respectively. Considerable amylase activity was observed in neutral to alkaline pH with optimum at pH 6.8. The optimal activity temperature of amylases was found to be 50°C, and the activity decreased dramatically at temperatures above 75°C.

It has been argued that life without water is impossible; eathly life began with water all aound. Ancient scripture has been quoted to drive the matter home. Woman-Water relationship is beyond controversy from the ancient time. It is a world wide phenomenon and very true in India. Human culture around the rivers in India is such that rivers are conceived as woman and somewhere as mother. The realationship between rivers and women has been shown with some detail.
TO THE QUESTION OF DEFINING ERRORS ARISING IN THE ANALYSIS OF SHIP STABILITY IN SHIP COMPUTER SOFTWARE

Published: August 2019

The article shows the need to account the difference between real weather conditiona and weather parameters given in shipboard computer software. Taking into account the fact that climatic conditions in the oceans are getting severer, it is unsafe to rely on relevance and reliability of the shipboard software forecasts navigating in zones with extreme weather conditions. Having the opportunity on board to get enough accurate weather forecasts in advance a navigator can competently plan the future voyage and avoid the expected storm. It not always possible to calculate the divergence with the storm and a vessel can be affected by cyclonic activity for different reasons. The ships stability is considered reached if the weather criterion shows the area ratio b/a > 1 on a static stability diagram. The analysis showed that for this case b/a = 0.436, which is 2.3 times less the minimum allowable value. It is stated that in the course of a ship operation the displacement and heights of center of gravity increase on the empty ship. If the ship stability is controlled by calculations, there occur random errors of due to inaccuracy of evaluating variable load. An increase of displacement and a height of center of gravity of an empty ship, as well as accidental errors due to inaccuracy of evaluation of deadweight may reach in total over 100 tons for displacement and up to 0,20 m for elevation of center of gravity. This fact should be taken into account in the shipboard software analyses. There have been given examples of formulas determining the displacement errors and a height of center of gravity of the vessel under operational load

Potential health risk due to the exposure of bacteria and fungi is mainly related to the concentration of respirable airborne bacteria and fungi in indoor environments. Schools buildings represent an important category of indoor environments. This study aimed to evaluate the concentration and size distribution of bacteria and fungi in classrooms of a public primary school in Beni Suef, Egypt. In addition, the indoor exposure dose (IED) of bacteria and fungi were estimated for children and teachers. A six-stage Andersen impactor was used for collecting the bacterial and fungal particles.  Indoor average concentration of bacteria was  1120±458 CFU/m3 while the corresponding fungal concentration was 291±89 CFU/m3. Bacterial level is almost twice the World Health Organization guideline value of 500 CFU/m3 while the fungal level is underestimated. Respirable fraction (<5 µm), that can reach to the lower airways of the lung, of bacteria was 79% while the corresponding respirable fraction of fungi was 90% of the total concentration. The size distribution of bacteria was bimodal in nature and the fungal size distribution was unimodal with lower dispersion than bacteria. IED of bacteria was 211 CFU/kg and 70 CFU/kg for children and teachers, respectively. While the fungal IED was 55 CFU/kg and 18.2 CFU/kg for children and teachers, respectively.

Radio Suara Surabaya (SS FM) is a private broadcasting institution capable of carrying out its role as a public radio. The uniqueness of its role begins with the switch of the SS FM function which originally dominated the content with entertainment into information content. This change in the dominance of content results in a two-way broadcast format, where there is interactivity in it. This study aims to find out about the interactivity that exists between SS FM and its listeners, including the media used, the forms of interactivity, and the factors of interactivity. Computer-Mediated Communication is one of the media theories used as a knife for analysis. Through qualitative research methods, it was found that in interactivity with the listeners, SS FM has standard rules that must be adhered to together. While the elements contained in it are participation, control and activity. In addition, the interactivity media used are telephone, online media and social media. Then the form of interactivity that occurs is interactivity of content and personal interactivity. While three factors cause listeners to interact actively with SS FM, namely the need for information, the need for self-actualization, and the need for self-existence.

Mutations identified in acute myeloid leukemia patients are useful for prognosis and for selecting targeted therapies. Detection of such mutations using next-generation sequencing data requires a computationally intensive read mapping step followed by several variant calling methods. Targeted mutation identification drastically shifts the usual tradeoff between accuracy and performance by concentrating all computations over a small portion of sequence space. Here, we present km, an efficient approach leveraging k-mer decomposition of reads to identify targeted mutations. Our approach is versatile, as it can detect single-base mutations, several types of insertions and deletions, as well as fusions. We used two independent cohorts (The Cancer Genome Atlas and Leucegene) to show that mutation detection by km is fast, accurate, and mainly limited by sequencing depth. Therefore, km allows the establishment of fast diagnostics from next-generation sequencing data and could be suitable for clinical applications.
