There was grounded the expedience of using “Amaranth” cryoadditive in the technology of processed cheeses. “Amaranth” cryoadditive contains necessary vitamins and microelements of the natural origin. The use of “Amaranth” cryopowder in the processed cheeses technology allows to enrich them with vitamins, mineral substances and food fibers. The main factors of introducing “Amaranth” cryoadditive were: the normative organoleptic estimation of a product and its daily need.

Introduction of “Amaranth” cryopowder in cheese masses results in the energetic value growth along with the treating-prophylactic effect. The complicated complex of chemical and biochemical compounds, included in the composition of “Amaranth” cryopowder, allows to relate it to products with the wide spectrum of treating-prophylactic and radio-protective properties.

Organoleptic characteristics of processed cheeses with cryopowder “Amaranth” testified that experimental samples of cheese keep the tender, elastic and resilient consistence. They have the specific original taste and smell (of cream butter). They had the homogenous picture on the cut, paste of the light-yellow or yellow color with separate dots of amaranth (black-red color). The surface of experimental samples was clean, shiny, correspondent to standards.

Experimental samples had the pleasant commodity look. Processed cheese, produced using “Amaranth” cryopowder, combines in itself traditional consumption properties with technological possibilities of functional-technological ingredients of the vegetable origin.

The offered products widen the assortment of milk products of the treating-prophylactic direction.

Published: May 2018

As a result of theoretical studies on problems of protection and prolongation of storage terms of meat, it was revealed, that one of promising directions is to use protecting coats, based on natural biopolymers.

The topicality of this study is in studying film-forming coats, based on natural polysaccharides, because they have high mechanical indices, absence of a smell, taste and are subjected to biological destruction. For regulating mechanical properties, the composition of film-creating coats is added with plasticizers of different origins.

The aim of this work is in describing characteristics of food films, based on carrageenan, sodium alginate and plasticizers of different origins.

There were mechanical, rheological properties of protecting coats. The comparative characteristic of these properties, depending on an added plasticizer, was realized. The type and mechanisms of interaction of components of the film-forming coat and plasticizers were completely described. The viscosity of the film-forming coat with a plasticizer has less values comparing with other solutions. Adding plasticizers resulted in increasing the film elasticity, but at the same time some increase of the firmness was observed.

Film-forming coats with adding a plasticizer had a higher limit of fluidity, so they were firmer than complex film-forming coats without a plasticizer. From the other side, deformation values of film-forming coats without adding a plasticizer were higher than ones of complex film-forming coats with adding a plasticizer, because they were firmer.

The study of physical properties of developed film-forming coats, based on hydrocolloids, demonstrated that coats with a plasticizer have more gas permeability.

According to the results, obtained at experiments it was established, that the film-forming coat, based on sodium alginate, carrageenan and glycerin, has best mechanical, physical and rheological indices.

Tipos de imaginación motora y procesamiento predictivo
Authors: Ezequiel Marengo Santiago
Published: May 2018

El entrenamiento con imaginación motora es una herramienta muy utilizada para mejorar la ejecución de técnicas deportivas. La teoría del procesamiento predictivo aplicada a la cognición ofrece una buena alternativa de explicación para este fenómeno, mostrando cómo fluye la información en el sistema motor mientras se ejecuta una acción y mientras se la imagina. Sin embargo, una errada taxonomía de los tipos de imaginación motora podría sentar las bases para construir un modelo de procesamiento predictivo que no explique ciertas peculiaridades que se dan en el entrenamiento de técnicas deportivas. En este sentido, propongo una corrección de la taxonomía estandarizada de modo que permita al modelo abarcar esas peculiaridades.
El lenguaje, Otro(s) en sí mismo: apertura y encuentro de la psique
Authors: Bañol López Walter
Published: May 2018

El lenguaje es la posibilidad posibilitante que posee el terapeuta (psicoanalista y psicólogo) de acercarse al mundo psíquico del paciente, pues este es el umbral que se abre ante su mirada analítica y observadora, y ante su oído atento y sagaz; efectuando de esta forma un encuentro con la construcción subjetiva que el paciente ha forjado de su vida en su ser histórico-lingüístico. De igual forma, el lenguaje posibilita acercarse al discurso social y a los imaginarios que este crea, como realidad intrínseca en el sujeto, puesto que es una constitución que se funda en la capacidad humana de otorgar sentido y significación a la realidad objetiva y subjetiva, vivida y experimentada en él. Por lo anterior, se permite acoger a el lenguaje como herramienta que facilita operar desde el discurso y los imaginarios insertados por y en la cultura, ya que estos otorgan una visión de la significación y del sentido que el hombre ha dado a su construcción psíquica y como este lo ha afectado, y de esta forma se facilitará la apertura y el encuentro con la psique del paciente.

Published: May 2018

Spline-gear-shaft (SGF), which is mainly composed of gear and spline shaft, is an important transmission system of RAT (driving the generator to output power with ram air). And its dynamic characteristics affect performance of RAT greatly. In this situation, gear coupling and spline coupling, must be taken into account when analyzing dynamics characteristics of SGF. The misalignment of axis for internal and external spline is inevitable owing to mass eccentricity and unconstrained in axial direction in a high-speed operation. Consequently, the dynamic model of SGF is established considering gear coupling and spline coupling based on whole transfer matrix method (WTMM) in this paper. In addition, numerical calculation method of meshing force for spline teeth under the condition of misalignment is presented considering the distribution force on contact surface of spline teeth in this paper, based on this, the coupled transfer matrix of misaligned spline coupling is established and the dynamic characteristics of SGF is analyzed using whole transfer matrix method with Riccati (WTMMR). The test experiments of dynamic characteristics for SGF are carried out by using portable vibration monitoring analyzer in this paper, furthermore, the time-frequency characteristics of SGF are analyzed through the analysis and processing of acceleration signal. The orders of magnitude for the first four natural frequencies with WTMMR are respectively consistent with experiment results, and the relative error is in the accepted range. Therefore, the correctness of solving meshing force and WTMMR for SGF are all verified. Moreover, it also shows that WTMMR is suitable for the analysis of complex coupled systems SGF and provides a new thought for dynamic analysis of complex shafting and promotes dynamic analysis to efficient and streamlined development.

Published: May 2018

Aiming at large-scale offshore wind turbine blades, governing equations in fluid domain and motion equations in structural domain with geometric nonlinearity were built by the aid of ALE method. A three dimensional model under fluid-structure interaction (FSI) was established by using UG software and Geometry module, and numerical calculation for FSI vibration characteristics of wind turbine blades under the effects of wind shear and fluctuating wind was carried out based on ANSYS Workbench. The results indicate that the contribution of the combined action to displacement and Mises stress chiefly derives from the wind shear effect, which not only causes a comparatively larger increase for the maximum displacement and Mises stress, but also becomes bigger and bigger with the increase of average wind speed, and the fluctuating wind effect is insignificant. The maximum value of Mises stress in the blade section appears at the relative wingspan of 0.55, the maximum Mises stress varying with relative span length decreases progressively from the middle to both sides of the blade, and the contribution of wind shear effect alone, the combined action or wind speed increment to stress also shows the same change rule. Furthermore, in the maximum stress section along wingspan, Mises stress along the direction of blade thickness or chord length respectively presents two distribution laws, and reaches the maximum on the blade surface.
An early fault feature extraction method for rolling bearings based on variational mode decomposition and random decrement technique
Authors: Zhu Chengcheng , Teng Kaiming
Published: May 2018

The early fault characteristics of rolling bearing are weak, and the background noise is so strong that it is difficult to diagnose. In order to solve the above problems, an early fault feature extraction method for rolling bearings based on variational mode decomposition and random decrement technique was proposed. The variational mode decomposition was used to decompose the collected vibration signals, and the component with the larger correlation coefficient was selected as the fault component. Then the fault component was processed by random decrement technology, and the Hilbert envelope spectrum of the fault component was made. According to the proposed method, the early fault characteristic of outer ring of rolling bearing was extracted. Compared with the method based on EMD, the proposed method is more effective in extracting the early fault characteristics of rolling bearings.

Authors: Bastos R. K. X. , Rios E. N. , Sánchez I. A.
Published: May 2018

A set of experiments were conducted in Brazil in a pilot-scale waste stabilization pond (WSP) system (a four-maturation-pond series) treating an upflow anaerobic sludge blanket (UASB) reactor effluent. Over a year and a half the pond series was monitored under two flow rate conditions, hence also different hydraulic retention times and surface loading rates. On-site and laboratory trials were carried out to assess: (i) ammonia losses by volatilization using acrylic capture chambers placed at the surface of the ponds; (ii) organic nitrogen sedimentation rates using metal buckets placed at the bottom of the ponds for collecting settled particulate matter; (iii) nitrogen removal by algal uptake based on the nitrogen content of the suspended particulate matter in samples from the ponds' water column. In addition, nitrification and denitrification rates were measured in laboratory-based experiments using pond water and sediment samples. The pond system achieved high nitrogen removal (69% total nitrogen and 92% ammonia removal). The average total nitrogen removal rates varied from 10,098 to 3,849 g N/ha·d in the first and the last ponds, respectively, with the following fractions associated with the various removal pathways: (i) 23.5–45.6% sedimentation of organic nitrogen; (ii) 13.1–27.8% algal uptake; (iii) 1.2–3.1% ammonia volatilization; and (iv) 0.15–0.34% nitrification-denitrification.

The study of the psychological features of young people of the Southern Russia received special relevance in the conditions of the changing political, economic and social situation. The youth was a reflector of progressive ideas on improvement of society at all times, and defended the human rights by the meetings, revolts andprotests, which are in essence aggression manifestations. If earlier protection of human rights and thirst of changes to the best were the purpose of similar performances, but now on the rise of extremist and terrorist groups, the creators of which use the desire of young people to achieve justice for their own purposes, making them dangerous to society actors. The question about the nature of similar processesremains to be opened. The article presents the results of a study on the types, severity and context of aggressive and hostile behavior, preferred strategies of behavior in conflict, the types of socially approved aggression and level of motivation of achievement / failureavoidance at 105 young girls of the Russian and Karachay nationalities, aged from 18 till 29 years. The analysis of contemporary literature, that demonstrates insufficient knowledge of the problem of aggressive and hostile behavior among young people, as well as its relevance, is carried out. The biological and social factors, that underlie aggressive behavior of the personality, are considered. According to the results of statistical data processing, the common features, inherent in representatives of both nationalities, and intra-group features are revealed. The emphasis is placed on the need to adjustment of ethno-cultural dialogue and on need of society in a significant reduction of the range of legitimizedaggression and in the strengthening of social control, because the legitimized aggression is a source of learning specific forms of aggressive behavior and ways for their implementation.

Published: May 2018

In the article such problem of professional education as influence of psychological barriers on learning efficiency is considered. Training, being process of interaction between the teacher and the student, has difficult structure with polymotivation of both parties. Very large number of factors – as the objective, connected with trainingconditions, and subjective, connected with the personality trainees and teachers, the relation of students to educational activity, existence of positive experience of overcoming of problems, etc. – has impact on the efficiency of such interaction. Training represents difficult system, which set of elements are connected among themselves as linearly, and probabilistically and not linearly. The structure of some system surely includes barriers which task is in preservation of integrity of systemand prevention of its disintegration. Educational activity of students consists of external and internal activities. Semantic barriers arise at students in educational activity and influence its efficiency. The semantic sphere of the person constantly develops that creates potential for an exit to new, higher levels of the development.Overcoming of the semantic barrier leads to improvement of quality of educational activity. Existence of rigid and stagnating semantic barriers brakes and distorts educational activity.

Published: May 2018

The article is devoted to the study of subjective picture of the world of adult men and women. The main guideline to clarify qualitative features of representations of the self and the world we took four worldview models proposed by V. M. Smirnov: chaotic, antagonistic, mechanistic, organismic worldview models. We analyzed the difference in the severity of these worldview models by men and women. We investigated the relationship between the severity of a particular model of the world and the various aspects of the representations on the basis of the results of the test “Who am I?”, the scale methodology “The meaning of life orientation”, methodology “My World: 20 out of 80”, “Incomplete sentences”, “Scale of satisfaction” that identifydifferent aspects of the relationship with the world, and significant others. In particular, we analyzed gender differences in terms of difficulty – easy way self-identification; the opposite trend of the world perception and its capabilities depending of the designationof gender identity at men and women; relationship representations of himself as a soul and the divine world order with the modalities of understanding of the world and its age features; the relationship of positive, neutral and negative characteristics of the world with the modalities of the worldview; communication of negative descriptionof the world with the appropriate perception of other spheres of life; analyzed the effect of denial of the particular modality of the worldview.

Due to the fact, that the most common modality of worldview is organismic modality is linked with the idea of self-representation as a spiritual nature, the article concludes about the meaning of this problem for the study not only at the level of a particular individual, but science in general.

Impacts of climate change on Livestock production and productivity and different adaptation strategies in Ethiopia
Authors: Tiruneh Solomon , Tegene Firew
Published: May 2018

This review work was conducted to explore the likely impacts of climate change on livestock production and productivity and different adaptation strategies in Ethiopia. National average temperature has increased by 10 c since the 1960s. Most of the livestock owners in the country perceive there is a climate change impacts on Livestock production and productivity. The major effects of climate change on livestock production include feed shortage, shortage of water, livestock genetic resources loss, reduced productivity, and decreased mature weight and/or longer time to reach mature weight in their order of importance. Higher temperatures resulting from climate change may increase the rate of development of certain pathogens or parasites that have one or more life cycle stages outside their animal host. Furthermore, the spatial distribution and availability of pasture and water are highly dependent on the pattern and availability of rainfall. Shortage of feed and water contribute to reduced productivity and reproductive performance of livestock. This includes slow growth rate of animals, loss of body condition, reduced milk production and poor reproductive performance in mature animals. Draught oxen that are emaciated and in poor body condition cannot provide adequate draught power for plowing, and thus affects crop cultivation. Bush encroachment as well as population pressure lead to diminishing availability of good pasture and hence to a decline in the total number of animals. Different adaptation options are followed by Livestock owners, such as Conservation of feed, out-migration of some household members to earn additional income, destocking, settlement and intensification of livestock production, undertaking supplementary income generating activities and awareness creation on the factors affecting climate change.
Abstract Animations for the Communication and Assessment of Pain in Adults: Cross-Sectional Feasibility Study
Authors: Jonassaint Charles R , Rao Nema , Sciuto Alex , Switzer Galen E , De Castro Laura , Kato Gregory J , Jonassaint Jude C , Hammal Zakia , Shah Nirmish , Wasan Ajay
Published: May 2018

Background

Pain is the most common physical symptom requiring medical care, yet the current methods for assessing pain are sorely inadequate. Pain assessment tools can be either too simplistic or take too long to complete to be useful for point-of-care diagnosis and treatment.

Objective

The aim was to develop and test Painimation, a novel tool that uses graphic visualizations and animations instead of words or numeric scales to assess pain quality, intensity, and course. This study examines the utility of abstract animations as a measure of pain.

Methods

Painimation was evaluated in a chronic pain medicine clinic. Eligible patients were receiving treatment for pain and reported pain more days than not for at least 3 months. Using a tablet computer, participating patients completed the Painimation instrument, the McGill Pain Questionnaire (MPQ), and the PainDETECT questionnaire for neuropathic symptoms.

Results

Participants (N=170) completed Painimation and indicated it was useful for describing their pain (mean 4.1, SE 0.1 out of 5 on a usefulness scale), and 130 of 162 participants (80.2%) agreed or strongly agreed that they would use Painimation to communicate with their providers. Animations selected corresponded with pain adjectives endorsed on the MPQ. Further, selection of the electrifying animation was associated with self-reported neuropathic pain (r=.16, P=.03), similar to the association between neuropathic pain and PainDETECT (r=.17, P=.03). Painimation was associated with PainDETECT (r=.35, P<.001).

Conclusions

Using animations may be a faster and more patient-centered method for assessing pain and is not limited by age, literacy level, or language; however, more data are needed to assess the validity of this approach. To establish the validity of using abstract animations (“painimations”) for communicating and assessing pain, apps and other digital tools using painimations will need to be tested longitudinally across a larger pain population and also within specific, more homogenous pain conditions.

Lecturers’ perception on students’ critical thinking skills development and problems faced by students in developing their critical thinking skills
Authors: Amin Astuti Muh. , Adiansyah Romi
Published: May 2018

Critical thinking emerges when learners attempt to use their background knowledge to construct meaning through interpreting, analyzing, and manipulating information in responding to a problem or a question that requires more than a single correct answer. Two factors that affect the improvement of the students’ critical thinking skills are lecturers’ activities and students’ activities. This study was a descriptive quantitative study which aimed to investigate (1) how lecturers perceive the development of students’ critical thinking skills and (2) drawbacks or obstacles that hinder the development of students’ critical thinking skills. The type of this research is a survey research with the descriptive quantitative approach. The research samples were taken from the population by using purposive sampling technique. Data was collected using a questionnaire, an observation sheet, and interviews. The research findings are 32.05% of the lecturers evaluated their students' critical thinking skills; therefore, promoting lecturers' awareness of developing students' critical thinking skills is necessary. In addition, the results of the present study also indicated that the development of students' critical thinking skills could interfere with many aspects including lecturers, students, frequencies of scientific meetings, and facilities.
Two sides of the same coin: Student justification for or against evolutionary theory
Authors: Yasri Pratchayapong , Maleesut Thanakorn
Published: May 2018

Students accepting evolution are likely to rely on science as cognitive authority (i.e. science textbooks and science teachers). In contrast, those not accepting are likely to rely on religion as cognitive authority (i.e. religious texts and religious leaders).  A thematic analysis based on existing quantitative and qualitative studies has been carried out in order to propose a theoretical framework for a range of reasons contributing to students' acceptance and rejection of evolutionary theory. This article urges that instruction of evolution is more than the matter of delivering scientific contents. It also deals with personal worldviews influenced by different forms of cognitive authority. It is therefore important to put more emphasis on developing students’ learning skills to critically evaluate which source of information is scientifically appropriate, with full respect to religious belief of individuals.

In Zoology course, students often have difficulty to identify several invertebrates. Android-based learning media is currently an alternative way of solving some problems during the learning process. Therefore, android-based learning media that assist students to identify invertebrates was developed in this study. This research method used to research and development model (R&D) developed by Borg and Gall (1983) that consisting 10 steps, that are research and data collection; planning the educational product; developing the product's preliminary form; initial field testing; the first revision of main product; main field testing; operational product revision; operational field testing; final product revision; and dissemination. The validation results from the material expert I, material expert II, and media experts were 96.6%; 94.3%; and 94.7%, respectively.  That results concluded I-Invertebrata was feasible for use in learning but requires minor revision. Furthermore, the results of quasi-experimental research that was analyzed by using analysis of covariance test showed the learning motivation of students who use I-Invertebrata is significantly higher than students who do not use I-Invertebrata.

Because of the high importance of bryophytes in forest ecosystems, it is necessary to develop standardized field sampling methodologies. The quadrat method is commonly used for bryophyte diversity and distribution pattern surveys. Quadrat size and the position of quadrats within the studied area have a significant influence on different analyses. The aim of the present study was to define the minimum quadrat size appropriate for sampling ground bryophytes in temperate beech forests, to compare two different field sampling methods for research on ground bryophytes, the random and microcoenose methods; and to test the adequacy of the microcoenose sampling method in temperate beech forests. Research was carried out on Fruska Gora mountain (Serbia) at four different sites. All sites contained temperate broadleaf forest vegetation, predominantly Fagus sylvatica, but also included various other tree species. Systematic sampling based on nested quadrats was used to determine the minimum sampling area. Random sampling was performed using 10 or 20 microplots (minimum area quadrat), randomly located within 10x10 m plots. Microcoenose sampling is a systematic sampling method based on the fact that every bryophyte fragment on the forest floor is a separate microcoenose. These methods were compared using the following criteria: species richness; Shannon?s diversity index and evenness measure; coverage of dominant species, and the time needed for sampling. The microcoenose sampling method has proven to be highly applicable in temperate beech forests in terms of species richness and diversity, in contrast to random sampling, which was not suitable for bryophyte flora with a patchy distribution.

Surface modification of titanium dioxide nanoparticles (TiO2 NPs) with the biologically active molecule pyridoxine hydrochloride (vitamin B6) was found to alter the optical properties. Microstructural characterization involving transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis revealed that the anatase TiO2 NPs had a narrow size distribution with an average diameter of 45 ?. The absorption onset of the surface-modified TiO2 samples was red-shifted by about 0.4 eV compared to the unmodified particles. The mode of binding between vitamin B6 and the surface Ti atoms was investigated by Fourier transform infrared spectroscopy (FTIR). From the Benesi? Hildebrand plot, the stability constant of the surface complex was found to be of the order 102 M-1. The experimental findings were supported by detailed quantum chemical calculations based on the density functional theory (DFT). Agreement was found between the experimentally measured absorption spectra of the TiO2 NPs surface-modified with vitamin B6 and the theoretically calculated electronic excitation spectra of the corresponding model system.

Objectives:

To evaluate if a 0.5-mm vertical bend applied on an incisor bracket produces movements in other planes and if different wires influence these effects.

Materials and Methods:

An acrylic model of a treated patient with brackets passively bonded was attached to an Orthodontic Force Tester, and a load cell was attached to the left lateral incisor. Thirty 0.019 × 0.025-inch archwires were divided into three groups according to their alloy: SS (stainless steel), B-Ti (beta-titanium), and MF (beta-titanium wire coated with nickel-titanium). Step-bends of 0.5 mm high were placed on the lateral incisor bracket using a universal plier, and the forces and moments in three dimensions were statistically analyzed by analysis of variance and Tukey post hoc test.

Results:

SS produced a larger force (3.4 N) than the B-Ti (1.41 N) and the MF (0.53 N; P < .001). Lingual forces were produced by the SS (0.82 N) and B-Ti (0.31 N) groups, while in the MF group, the force was insignificant. SS produced a mesial force of 0.24 N, while the B-Ti force was insignificant and MF produced 0.09 N. Groups produced different crown-distal tipping moments (SS = 31.48 N-mm, B-Ti = 11.7 N-mm, and MF = 4.55 N-mm) and different crown-buccal tipping moments. SS produced larger moments (3.63 N-mm) than B-Ti (1.02 N-mm) and MF (0.36 N-mm) wires. A mesial-out rotational moment was observed in all groups (SS = 7.17 N-mm, B-Ti = 3.46 N-mm, and MF = 0.86 N-mm).

Conclusions:

A 0.5-mm intrusion bend produced lingual and mesial side effects. In addition to the distal and buccal crown-tipping moments, there was a mesial-out moment. Compared with SS, B-Ti and MF wires produced lower forces. These more flexible wires showed side effects with lesser intensity.
