Spoilage bacteria pseudomonas - production of hydrolytic enzymes and ability to grow at 5°C
Authors: Sternisa Meta , Cargo Mihael , Smole-Mozina Sonja
Published: December 2019

Microbial growth and metabolism in food leads to organoleptic spoilage
through altering colour, odour and texture of food, and slime or liquid
production on the surface. In the dynamics of organoleptic spoilage, initial
microbial contamination and storage temperature of food play an important
role. Bacteria Pseudomonas are known as the most common spoilage bacteria.
Aim of this study was to evaluate the ability of selected Pseudomonas
strains to grow at 5?C in different food models, and to evaluate their
spoilage potential as the ability to produce different hydrolytic enzymes at
5?C. This was determined through monitoring the number of bacterial cells
in food models at 5?C, over 9 days of incubation, and on agars for
detection of proteolytic and lipolytic activity. Of the four selected
Pseudomonas strains (P. fragi CC151, P. fragi CC275, P. psychrophila CC291,
P. lactis CC194), all were capable of producing lipolytic and proteolytic
enzymes. When monitoring Pseudomonas growth in different food models (minced
meat, pasteurized milk, apples) as compared to broth, the best growth was
achieved in minced meat model, and the lowest in apple model. Thereby, the
importance of the nutrients availability and the use of hydrolytic enzymes
to exploit more complex nutrient molecules, especially proteins, has been
confirmed. Selected Pseudomonas strains are able to grow in a variety of
food media, and have the ability to produce hydrolytic enzymes, confirming
their universality as refrigerated food spoilers, with high potential of
persisting in the food storage environment.

Published: December 2019

Libya is one of the considerable olive oil producers in North Africa. The
consumption of olive oil in this country is part of the cultural heritage
and a large number of individual manufacturers produce oil applying the
process of cold pressing. The aim of this work was to determine the sensory
profile and some main chemical characteristics, as free fatty acids,
peroxide value, total phenols content and induction period of virgin olive
oils. Oil samples were extracted from a blend of three olive cultivars
typical for Libya: Roghiani, Hammudi and Endori, harvested in five different
regions of northern Libya in the crop year 2015. Obtained results have shown
that investigated olive oil samples were characterized by different sensory
profile and chemical characteristics, due to peculiar effect of harvest
areas of olive fruit. On the basis of investigated attributes, some oils
were of excellent quality, but other were under. The free fatty acid
contents varied between 0.73% to 2.78 % of oleic acid, peroxide values
ranged from 6.40 mml/kg to 13.65 mmol/kg and induction period from 4.89 h to
18.33 h. The content of total phenols, as especially important compound for
health benefit of olive oil, was also significantly various, from 56.0 to
238.3 mg GAE/kg of oil. It can be concluded that the oil from Gharyan
production region was quite different from the other Libyans? olive oils.
This oil had the best sensory profile, basic chemical quality, oxidative
stability and the highest phenolic content.

Published: December 2019

Bisphenol A is a monomer used primarily in the production of polycarbonate
plastics and epoxy resins. Polycarbonate plastic is used in a wide variety
of digital media products, electrical and electronic equipment, sport safety
equipment, reusable food and drink containers, etc. Epoxy resins are used in
engineering applications, paints and adhesives and also in a variety of
protective coatings in metal cans for foods, bottle tops and water supply
pipes. The content of BPA was evaluated in 16 samples (6 baby bottles and 10
drinking containers - can) collected during 2018/2019, of which three baby
bottles and 8 cans were collected in 2018, while three baby bottles and 2
cans in 2019. A simple HPLC-FLD analytical method was validated for the
quantitation of BPA from baby feeding bottles and cans. The separation was
performed on a C18 column. Good linearity was obtained over the
concentration range of 0.3-6.0 ?g/mL with the regression coefficient (R2) of
0.9998. The limit of detection (LOD) and limit of quantification (LOQ) were
0.01 and 0.03 ?g/mL, respectively. The repeatability of the method (%RSD)
was between 4 and 6%, while the recovery ranged from 104.3 to 109.7%. The
extraction of BPA was done in accordance with SRPS EN 13130-1:2008. The
methods were applied to determine BPA release from baby bottles, performing
repeated procedures according to EU and national regulations (SRPS CEN/TS
13130-13 (2008)). The conformity was evaluated according to National and EU
requirements. The results show that Bisphenol-A was not detectable in any of
the analysed samples.

Published: December 2019

This study is concerned with the effect of different cultivation techniques
on enzymes production from sugar beet pulp by strain Neurospora crassa
isolated from the environment. Cultivation of selected producing
microorganism was carried out under the same process conditions using five
techniques. Bioprocess efficacy was estimated based on amylolytic,
cellulolytic and xylanolytic activity of prepared enzymes mixtures. The
obtained results indicate that the selection of cultivation technique had a
statistically significant effect on the production of examined hydrolytic
enzymes. It was confirmed that solid state cultivation with spontaneous
aeration is the best cultivation technique for the production of amylolytic,
cellulolytic and xylanolytic enzymes from sugar beet pulp by Neurospora
crassa. Submerged cultivation of producing strain with spontaneous aeration
resulted in the lowest production of all investigated enzymes under applied
experimental conditions. The obtained results are the basis for further
research aimed to increase the enzymes yield and activity of their mixture.

Published: December 2019

This contribution treating a lesser-known part of Isidora Sekulic's biography
(1877-1958) highlights several documents (published for the first time) on
her admission to Serbian citizenship. Isidora Sekulic had been employed as a
teacher in the Senior Girls' School in Sabac in 1909. Like every other
citizen, she had to become a Serbian subject and get Serbian citizenship in
order to gain permanent employment in the civil service and the right to
pension. She first had to be dismissed from Hungarian citizenship. After a
long procedure, she received Serbian citizenship in 1910. Among the
published documents is also the Oath, which was repeated by Isidora Sekulic
at her swear-in ceremony during the admission to Serbian citizenship before
a priest in Sabac. The overall contribution also brings several unknown

Psychological Difficulties of Nursing Students
Authors: Takšić Iva , Petrak Olivera , Perković Lada
Published: December 2019

The research of students adapting to university
life, difficulties in coping with the academic demands, and personal problems
students face during their study is important for a better understanding of
their needs in order to prevent possible mental health problems in the student
population and increase the overall quality of study. When researching the
difficulties that students face, one of the important factors to be taken into
account is the type of study, for instance whether they study full or part time.
Since nursing students represent the largest student population at the
University of Applied Health Sciences in Zagreb, Croatia, we investigated the
differences in the perceived difficulties during studying between full-time
undergraduate nursing students and part-time specialist graduate nursing
students, most of whom already work as professional nurses. In a sample of 231
participants, there were 143 undergraduate students with the average age of
26.38 years (90.2% females) and 88 specialist graduate students with the
average age of 37.52 years (95.5% females). We examined the frequency of 62
difficulties that students may encounter during their study using a survey by
the Student Counselling Centre at the Faculty of Philosophy in Zagreb. On
average, nursing students perceived 12 difficulties. The most frequent
difficulties all students struggle with are nervousness or tension, financial
problems, fear of failure, inefficient time management, insecurity, and changes
in eating habits. There is no significant difference in the total frequency of
perceived difficulties between undergraduate and graduate students but we found
significant differences between these two groups in the number of students who
encountered particular difficulties regarding 13 issues. Undergraduate students
face problems with roommates and problems in communication with professors more
often than graduate students, while graduate students struggle the most with
financial problems and adapting to the
study regime. When faced with problems, 65.4% of all students would seek free
psychological counselling. Graduate students and students who perceive more
difficulties are more willing to seek psychological support.

Published: December 2019

The article focuses on the problem of structure degradation and ecosystem functioning – the urgency that identifies the relevance of operations at a strategic level aimed at providing the integrated assessment of ecological stability of water. Determination of water quality indicators were divided into blocks according to the criteria of salt composition, according to chemical saprobological indicators and the content of specific substances of toxic and radiation action. According to the results of block analysis, the integrated ecological index of water quality was determined by the dependence of water quality on the indicators of ecological stabilization of the landscape and the structure of biotechnical elements. The article determines the relationships between worsening quality of surface waters and stabilization or destabilization of the landscape structure. The research was conducted on medium and large streamflows on the Right Bank of Polesie region of the Dnieper-River cascade within which the tracts of land were identified and the landscape ecological stability (CESL1) and landscape biotechnical elements coefficients (CESL2) were determined. The retrospective analysis was performed of the surface water features on the Right Bank of Polesie region of the Dnieper-River cascade and the main trends in salt block indicators, trophic and saprobiological block indicators, and in the content of toxic and radioactive substances at observation sites were estimated. Based on obtained data, the integrated assessment in trends of surface water quality on the Right Bank of Polesie region of the Dnieper-River cascade was made and the main parameters and scale of stabilization and destabilization of landscape impact on the water quality formation were defined.

Published: December 2019

Drought is an extreme event that causes great economic and environmental damage. The main objective of this study is to evaluate sensitivity, characterization and propagation of drought in the Upper Blue Nile. Drought indices: standardized precipitation index (SPI) and the recently developed standardized reconnaissance drought index (RDIst) are applied for five weather stations from 1980 to 2015 to evaluate RDIst applicability in the Upper Blue Nile. From our analysis both SPI and RDIst applied for 3-, 6-, 12 month of time scales follow the same trend, but in some time steps the RDIst varies with smaller amplitude than SPI. The severity and longer duration of drought compared with others periods of meteorological drought is found in the years 1984, 2002, 2009, 2015 including five weather stations and entire Upper Blue Nile. For drought relationships the correlation analysis is made across the time scales to evaluate the relationship between meteorological drought (SPI), soil moisture drought (SMI), and hydrological drought (SRI). We found that the correlation between three indices (SPI, SMI and SRI) at different time scales the 24-month time scale is dominant and are given by 0.82, 0.63 and 0.56.
Limiting horizontal water filtration using drainage-screened modules
Authors: Klimov Serhii , Pinchuk Oleg , Kunytskiy Serhii , Klimova Anastasiia
Published: December 2019

In the context of climate change, it is important to minimize the changes that are introduced in the territory adjacent to the object of human economic activity. In some cases, this can be done with the help of drainage-screened modules – an anti-filtration screen that redistributes the zone of influence of the drain placed near it. As a result, the drain regulates to a greater extent the zone of human economic activity (drainage system, tailing dump, populated area, etc.) and to a lesser extent lowers the level of groundwater in the adjacent territory. The use of drainage-screened modules in tailing farms, for the organized storage of mineral waste of enterprises makes it possible to increase the filtration stability of dike, ensuring the uniform operation of the tailing dams, as well as reliable removal of intercepted groundwater. This is achieved because in the tailing farm the dikes are intensified by drainage-screened modules. Water, filtered through the body of the dike and under it, is intercepted by a drain. A part of the filtration flow, which is not intercepted by the drain, is stopped by the anti-filtration screen.

Published: December 2019

This investigation was undertaken to determine the optimum conditions for physical-chemical treatment of waste water contaminated with heavy metals in the industry of metallic coatings. The industry uses substances such as: inorganic acids, alkalis, acidic and alkaline metal salts, that has a high water demand in the processes of flushing and cleaning the parts to be coated. According to the preliminary characterization of samples and reported in the literature theory, physico-chemical process was implemented for the removal of contaminants that consisted in chemical oxidation of CN-ions, followed by chemical precipitation made next to a coagulation/flocculation and subsequent adsorption on activated coal. Laboratory scale tests showed the optimal conditions of treatment including chemical oxidation by the addition of 4.15 cm3 of H2O2 (30%) per gram of CN, chemical precipitation with NaOH to a pH of 12, followed by coagulation/flocculation with Fe2(SO4)3 at a speed of 135 rpm for 3 min and 20 rpm for 20 min and finally the addition of 1.0 g of adsorbent previously activated at 700°C. From this study, it is clear that the adsorption on activated carbon is highly efficient in the removal of heavy metals from industrial waste water from electroplating. However, it is also clear that the parallel application of the treatments, shown here, is more effective to completely remove contaminants such as lead, nickel, silver, and copper at laboratory scale, so it is recommended the simultaneous use of these physico-chemical processes.

Published: December 2019

A situation in which appears at the same time a competition and cooperation between the subjects is defined as a coopetition. First of all it is considered at the mezo level – between the companies, but it can be analysed at the micro level – inside the organization. In the second case, it concerns shaping the relations among the employers which compete one with another and at the same time they cooperate. Among the organizations where the coopetion can be analysed we distinguish two types - for profit and non profit. A difference of the functioning of the for profit and non profit organizations can be seen among other things in the differences that refer to the shape of the coopetition. In the article the characteristic of a intraorganizational coopetition in the for profit and non profit subjects was presented. The base to formulate the conclusions was formed by the investigations made in which, to collect the data there were used the semistructure interviews with six sample selected organizations – three for profit and three non profit.

Authors: Kazmierczyk Jerzy , Tarasova Anna , Andrianova Elena , Baszynski Adam
Published: December 2019

Outplacement is a rare HRM tool; hence there is also a lack of research on it. In turn, banks are treated as enterprises that implemented modern management solutions faster than other companies in the countries of Central and Eastern Europe. The bank is a good entity for outplacement testing. Both Poland and Russia belong to the CEE countries. The Polish economy has been promoted to a group of developed countries. The Polish banking sector relies much more on foreign capital than in Russia, which may be important for the development of outplacement. The main aim of this paper is to reveal and explain the differences in the popularity of outplacement in Russian and Polish banks. This article uses survey data collected in Poland and Russia from over 2,000 bank employees. Mann-Whitney test, correlations and discriminant analysis were used. Employees of the Polish banking sector more often than Russian workers noted the absence of any support for dismissed workers (Poland 30%, Russia 23%). Available outplacement forms differentiated in Poland and Russia. A little more focus on counselling support was observed in Poland, and on material support in Russia. The most important factors influencing outplacement were: occupied position, size of locality, sex, work experience in banking, country.

A Survey of High-Efficiency Context-Addaptive Binary Arithmetic Coding Hardware Implementations in High-Efficiency Video Coding Standard
Authors: Tran Dinh - Lam , Pham Viet - Huong , Nguyen Hung K , Tran Xuan - Tu
Published: December 2019

High-Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is the newest video coding standard developed to address the increasing demand for higher resolutions and frame rates. In comparison to its predecessor H.264/AVC, HEVC achieved almost double of compression performance that is capable to process high quality video sequences (UHD 4K, 8K; high frame rates) in a wide range of applications. Context-Adaptive Baniray Arithmetic Coding (CABAC) is the only entropy coding method in HEVC, whose principal algorithm is inherited from its predecessor. However, several aspects of the method that exploits it in HEVC are different, thus HEVC CABAC supports better coding efficiency. Effectively, pipeline and parallelism in CABAC hardware architectures are prospective methods in the implementation of high performance CABAC designs. However, high data dependence and serial nature of bin-to-bin processing in CABAC algorithm pose many challenges for hardware designers. This paper provides an overview of CABAC hardware implementations for HEVC targeting high quality, low power video applications, addresses challenges of exploiting it in different application scenarios and then recommends several predictive research trends in the future.

Policy on the Implementation of the Law on Execution of Criminal Judgments - Some the Oretical Issues
Authors: Chi Nguyen Ngoc
Published: December 2019

Policy on the law on execution of criminal judgments is an area of criminal policy that has a tremendous role in preventing and fighting crimes as well as in actualizing the criminal liability of legal entities and natural persons committing crimes. Studying the policy on the law on execution of criminal judgments, therefore, is an urgent requirement in the current period of national development, international integration and judicial reform. Nevertheless, comparing to studies in the criminal field, in criminal procedure and crime prevention fields, policy studies on the law on execution of criminal judgments stay rather modest and have not yet met theoretical and practical requirements. To contribute to remedy this situation, this paper will focus on clarifying certain theoretical issues on the policy on the law on execution of criminal judgments so as to somewhat answer the questions below: (i) What’s the current progress of research on the policy on the law on execution of criminal judgments in Vietnam? On what the level? And what are the issues that need to be addressed to continue study? (ii) Definition, nature and characteristics of the policy on the law on execution of criminal judgments? (iii) Policy on the law on execution of criminal needs to be developed on which basis? Subjects and methods for developing the policy on the law on execution of criminal judgments? (iv) Policy on the law on execution of criminal judgments needs to englobe which issues? (v) What’s the relation between the policy on the law on execution of criminal judgments and the development and implementation of the law on execution of criminal judgments?

            To study these issues, the author use methods of analysis, comparison and synthesis under the foundation of the dialectical method and the human rights-based approach to put research issues in connection with growth and development on the basis of respecting, guaranteeing, protecting human rights in the field of execution of criminal judgments

Authors: Zaamoune Faiza , Menacer Tidjani , Lozi René , Chen Guanrong
Published: December 2019

In this paper, hidden bifurcation routes to multiscroll chaotic attractors generated by saturated function series are explored. The method to nd such hidden bifurcation routes (HBR) depending upon two parameters is similar to the method introduced by Menacer, et al. (2016) for Chua multiscroll attractors. These HBR are characterized by the maximal range extension (MARE) of their attractors and coding the appearance order of the scrolls under the control of the two parameters. Moreover, these HDR have interesting symmetries with respect to the two parameters. The novelty that this article introduces, is firstly the paradigm of MARE and the formula giving their approximate value depending upon parameters p and q, which is linked to the size of the scrolls; secondly the coding of the HBR which is dened for the first time including the basic cell; and thirdly unearthing the symmetries of these routes, allowing to obtain their coding without any numerical computation.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

Published: December 2019

Our main goal in this article is to present the approaches and examples of three functions in R consist of optim, nleqslv and maxLik function to detect the optimization solution of the estimating function in the regression models. We then compare the results with numerous sample sizes (n=150, 300 and 500), the execution time of R code, as well as Normal Q - Q plots of three approaches through some of regression models such as the zero-inflated Binomial (ZIB) regression model, logistic regression model, the zero-inflated Poisson (ZIP) regression model and the zero-inflated Bernoulli (ZIBer) regression model. Finally, we discuss potential research directions in the coming times.  This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

Authors: Galán Casado Diego , Castillo Algarra Jaquina , García Tardón Bruno
Published: December 2019

Las personas con Trastorno Mental Grave (TMG) pueden presentar estilos de vida  poco saludables (Huizing et al., 2011), lo que redunda negativamente en su salud física y en la propia enfermedad. Conociendo que el ejercicio físico regular mejora tanto la salud física como el estado emocional y el bienestar personal (Mullor et al., 2017), nos planteamos investigar las consecuencias de un programa deportivo en personas con TMG. Para ello seleccionamos una liga denominada Ligasame, dirigida a personas con TMG integradas en diferentes recursos de rehabilitación psicosocial de la Red de Atención a Personas con Enfermedad Mental de la Comunidad de Madrid y Asociaciones de Familiares, por ser una experiencia consolidada el tiempo que integra a 15 equipos de fútbol. El objetivo de este trabajo es conocer las consecuencias de este programa de fútbol en las personas con TMG que participan en el mismo, a través de la percepción de 26 profesionales de Ligasame que trabajan para las asociaciones o recursos integrados en la misma. En esta investigación, con un diseño cualitativo emergente (Hernández, Fernández y Baptista, 2006), se analizaron 26 cuestionarios de respuestas abiertas, diseñado ad-hocpara el estudio, destinado a estos profesionales. Los resultados obtenidos muestran que un programa deportivo para personas con TMG mejora su condición física, favorece sus relaciones sociales, mejora su autoestima, reduce sus niveles de estrés y ansiedad y potencia aspectos transversales como la utilización de las nuevas tecnologías o la igualdad de género.  Asimismo, ayuda a reducir el estigma que sufren estas personas, tanto socialmente como a nivel personal y familiar.
El Yoga como método cuerpo-mente para mujeres embarazadas con depresión: una revisión sistemática
Authors: Nieto Sánchez Julián , Granero-Gallegos Antonio , Carrasco Poyatos María
Published: December 2019

Introducción: La Organización Mundial de la Salud considera la depresión prenatal como un gran problema de salud pública que actualmente afecta entre el 10-20% de las mujeres gestantes, debido principalmente a la gran liberación de la hormona cortisol durante el embarazo. En los últimos años, algunas disciplinas como el Yoga, considerado como un método cuerpo-mente formado por técnicas de respiración, posturas físicas (Asanas) y meditación/relajación, ha ganado importancia como terapia alternativa contra la depresión prenatal por su relación con los índices y los síntomas de ansiedad o estrés en mujeres gestantes. Objetivo: Realizar una revisión sistemática para comprobar el efecto del Yoga como método de trabajo cuerpo-mente en mujeres embarazadas con depresión. Método: Siguiendo la Declaración Prisma, se buscó en las siguientes bases de datos: Pubmed, Scopus, Medline, Current Contents Connect, Ebsco, Web of Science y CINAHL-Complete artículos publicados en los últimos 10 años y teniendo en cuenta unos criterios de inclusión y exclusión específicos. La estrategia de búsqueda fue: “(Yoga) AND (Pregnant OR Prenatal OR Antenatal) AND (Depression)”.  Se seleccionaron siete trabajos con calidad metodológica ≥6 según la escala PEDro. Resultados: Los artículos que obtuvieron resultados favorables (n=4) presentaban: alta participación (n>90 sujetos), buen periodo de seguimiento de los sujetos (n≥12 semanas) y alta calidad metodológica (n≥7 puntos). Los artículos con resultados desfavorables (n=3) presentaban: baja participación (n<60 sujetos) y escaso periodo de seguimiento (n≤9 semanas). Conclusión: El Yoga ha resultado ser una terapia alternativa favorable para reducir los índices de depresión en mujeres gestantes.
Mirror Symmetry Breaking in Micelles of N-Stearoyl Serine Enantiomers
Authors: scolnik yosef
Published: December 2019

Circular dichroism spectra were recorded for micellar aggregates of N-stearoyl (L or D) serine in H2O or D2O. Micelle formation kinetics differed markedly in H2O, but in D2O the enantiomers showed similar spectral characteristics. The results confirm previous observations (1) that described differences in the thermodynamic properties of enantiomers, in contrary to the reigning dogma. The comparison of spectral properties indicates that this phenomenon depends on the interactions with H2O and is not due to trivial contamination.

10 Things to Know About the Shape of Ohio's Skilled Workforce15
Authors: Dunne Timothy , Venkatu Guhan
Published: December 2019

A region’s economic performance is closely linked to the skills and knowledge of its workforce. Using college attainment as a measure of workforce skills, we examine overall trends in higher education to get a sense of where Ohio stands relative to other states. The data reveal that Ohio has made some progress, especially in improving educational attainment in its younger workers. At the same time, Ohio lags in a number of other dimensions, in particular, in its overall level of college attainment and in attracting educated workers into the state.
Gaps versus Growth Rates in the Taylor Rule
Authors: Carlstrom Charles T. , Fuerst Timothy S.
Published: December 2019

There are many possible formulations of the Taylor rule. We consider two that use different measures of economic activity to which the Fed could react, the output gap and the growth rate of GDP, and investigate which captures past movements of the fed funds rate more closely. Looking at these rules through the lens of a partial-adjustment Taylor rule, we conclude that the gap rule does a better job of explaining the actual funds rate data, and provides a better rule-of-thumb for understanding historical monetary policy.
