Background: Gestational weight gain (GWG) is physiological change in pregnancy. Inadequate gestational weight gain (IGWG) and excessive gestational weight gain (EGWG) can pose a risk of complication such as gestational hypertention, low birth weight, giant baby, and premature birth. Food intake (energy and macronutrient) play important role in providing pregnancy needs such as fetal and placental growth, and also play role in fat accumulation in some part of mother’s body. Objectives: This study aims to analyze the relationship between energy intake and macronutrient and gestational weight gain of pregnant woman and to know the consumption of food groups.Methods: This study was quantitative study using cohort prospective approach. 73 healthy pregnant women with normal body fat mass who met inclusion and exclusion criteria was weighed twice in a period of 8 weeks. 24 hours food recall in 2 unsecutive days was done between those times. The instruments used for this study were weight scale, stadiometer, and questionnaire. Nutritional analysis used Nutrisurvey and statistic analysis used Chi Square test.Result: There was a relationship between total energy intake and gestational weight gain ( p = 0.031) and there was no relationship between macronutrient component intake (carbohydrate, fat, and protein) and gestational weight gain (p = 0.175, p = 0.97, and p = 0.089 respectively). Respondent characteristic that has corelation with GWG is number of pregnancy. Most pregnant woman experienced EGWG (56.2%) and their food consumption not fulfilled the balance nutrient recommendation guidelines especially less in vegetables and fruits consumption.Conclusion:There is a significant corelation between energy intake and GWG.

An experiment was performed to investigate the probiotic effect of Saccharomyces boulardii and Saccharomyces cerevisiae on yield, antioxidant activity, and expression of interleukin-6 gene in Holstein calves. Sixteen calves were divided into 4 dietary treatments with 4 calves/treatment. Experimental treatment diets include 1) control (without probiotic use), 2) milk soluble probiotics based on S. boulardii (1 g/kg), 3) milk soluble probiotics based on S. cerevisiae (1 g/kg) and 4) A mixture of yeast probiotics S. boulardii and S. cerevisiae as a solution in dairy milk (1 g/kg each). The completely randomized design was used in this experiment. The results showed that feeding S. boulardii and S. cerevisiae did not have a significant effect on performance traits compared with control. There was no significant difference between the different treatments for the number of antioxidant enzymes compared to the controls. Superoxide dismutase (SOD) in the treatments used probiotics were higher than the control. The expression of interleukin-6 gene expression was increased significantly (P<0.05) for treatments 3 and 4 on Days 10, 30 and 60 compared to the control. In conclusion, addition of probiotics did not alter performance traits of antioxidant activity, but the S. cerevisaetreatment did increase interleukin-6 gene expression which suggests an effect on the immune system.

Which species perform best in carbon sequestration and storage in planted forests? A review of the potential of Pinus and Eucalyptus
Authors: Silveira C.S. , De Oliveira L. , Talamini E.
Published: December 2020

The carbon market has been attracting attention as an additional source of revenue associated with growing planted forests. In addition to the economic importance, planted forests play an essential role in mitigating climate change due to their high potential to sequester carbon from
the atmosphere and store it in soil, biomass or litter. Therefore, forest cultivation and the carbon market present win-win opportunities for both the economic and ecological systems. One question that arises for those who intend to invest in planted forests projects for carbon credits trading
is: which species within Pinus or Eucalyptus, performs better in Carbon Sequestration and Storage (CSS)? Based on a systematic review of the scientific literature, we ranked the cultivated species of the genus Eucalyptus and Pinus based on their CSS performance.
The findings suggest that Eucalyptus performs slightly better than Pinus, given that this supremacy was reported in 60% of the studies analyzed. However, paired analysis between species show that Pinus patula , P. halepensis, and P. radiata presented better
performance than Eucalyptus saligna, E. occidentalis, and E. globulus, respectively. At the same time, Eucalyptus spp., E. cloenziana, E. grandis, and E. tereticornis performed better than Pinus spp., P. armandii, P. massoniana,
P. taeda, P. caribaea, and P. roxburghii, respectively. However, species' effective performance in sequestering and storing carbon depends on other issues such as technical factors, management practices, and biophysical conditions. We identified that biophysical conditions,
such as the site index, soil type, soil density, stand elevation, water deficit, soil clay, aluminum content, edaphoclimatic conditions and land use change were the most important. Thus, besides the species to be cultivated, the potential for generating carbon credits by planted forests also
depends on local biophysical conditions and management practices adopted.

SARS-CoV-2, the novel coronavirus strain responsible for the current pandemic of COVID-19, has rendered the entire humanity suffering. Several months have passed since the pandemic has struck. However, the world is still looking for an effective treatment plan to battle the viral infection. The first vaccine just received emergency approval in December 2020 for use in USA and UK. These are excellent news, however, the worldwide distribution of such vaccine, the possibility of virus mutation and the lack of data regarding the long-term effects of such vaccines are a significant concern. In addition, although remdesivir was recently approved by the FDA to be used as a clinical drug against COVID-19, it hasn’t stood out yet as a proven form of therapeutics. Such inability to produce a novel therapy has caused enough inconveniences for the affected people worldwide. Repurposing the already available drugs to fight against the virus seems to be a reasonable option amidst such uncertainty. Given the vast collection of potential treatment candidates to be explored against COVID-19, there is a decent chance that a success in this regard will serve the intermediary purpose of clinically treating the infection until a COVID-19 vaccine is widely distributed worldwide and will be able to treat COVID-19 patients that do not adequately respond to vaccines. Such treatments may prove very useful in future coronavirus outbreaks too. Proper research into these repurposing treatments may yield a certain insight into the field of novel treatment production as well. This review study accumulates a relevant set of information about drugs and vaccines against COVID-19, in terms of their repurposing properties and the specific phases of clinical trials they are undergoing across the world. A potential timeline is also suggested to estimate when an effective result can be expected from the ongoing clinical trials for a better anticipation of the drug landscape. This study will hopefully help accelerate investment of resources into development and discovery of drugs and vaccines against the infection.

In this work tannin was isolated from the outer bark of the eucalyptus tree, then treated with Ba(OH)2 to synthesize barium tannate (Ba-tan). The derivative was evaluated as a thermal stabilizer for polyvinyl chloride (PVC). PVC was mixed with Ba-tan thermally at four percentages (0.5, 1.0, 2.0, and 2.5)% w/w. The samples were pressed thermally to films having thickness ranging between 0.25 and 0.30 mm. The effect of Ba-tan was studied by monitoring the weight of samples under iso-thermal conditions at 250 oC. Thermal stability of PVC increased with increasing Ba-tan percent. Samples weight curves also indicated that the additive had been suitably active to increase the resistance of PVC against thermal degradation, where the degradation rates decreased from about 0.21 % wt/min. at 0.5% of Ba-tan on PVC to reach to 0.05% wt/min. for the 2.5% treated sample. The ability of Ba-tan to react with and remove HCl from the system of polymer during thermal conditioning of samples and during the measurement led to this effect. Therefore the present results demonstrate the performance of this derivative as a thermal stabilizer.
Alternative Medicine and Magical Thinking

Published: December 2020

The 21th century witnesses a boom of ‘alternative medicine’, i.e. medicine-man practices, that draw their origins from the times of old. The so called ‘alternative medicine’ prospers, when academic medicine fails—in the cases of complex, chronic, age diseases, lack of financing or social crises. «Alternative medicine» is based on magical thinking. The latter is grounded on passion for health despite the objective life setting. A representative of academic medicine, as usual, is called to oppose magical thinking with education, prophylactics, and personal example.

New experimental data for differential cross-sections of the reaction 14C(11B,10B)15C at Еlab(11B) = 45 MeV were obtained for transitions to the ground and excited states of the exit reaction channel nuclei. The experimental data were analyzed within the coupled-reaction-channels method (CRC). The 14C + 11B elastic scattering channel as well as channels for one- and two-step transfers of nucleons and clusters were included in the coupling scheme. The Woods - Saxon (WS) potential was used in the CRC-calculations for the entrance reaction channel with the parameters deduced previously from the analysis of the experimental data of 11B + 14C elastic and inelastic scattering, whereas the WS potential for the exit 15C + 10B reaction channel was deduced from the fit of CRC cross-sections to the 14C(11B,10B)15C reaction experimental data. Needed for CRC-calculations spectroscopic amplitudes (factors) of the nucleons and clusters transferred in the reaction were calculated within the translational-invariant shell model. The mechanisms for one- and two-step transfers of nucleons and clusters were investigated in this reaction. The 15C + 10B potential parameters were deduced, and comparisons of the CRC reaction cross-sections calculated with the 15C + 10B and 12,13C + 10B potential parameters were performed. The differences between these CRC calculations were observed, e.g. "isotopic effects" were observed for the potentials of 10B interaction with 12,13,15C carbon isotopes.

Standard approaches to the construction of maps of radioactive contamination do not provide errors in map data, so such maps do not, in fact, guarantee the accuracy of the map information. In this paper, based on the fact that the characteristics of radioactive contamination at a particular point in the territory have a lognormal probability distribution, a methodology for creating maps with a guaranteed confidence level of the provided information has been proposed and tested. There are considered two ways of creating maps, based on the results of "direct" measurements of radioactive contamination characteristics and in the combination of "direct" and "indirect" measurements of values statistically related to the mapping characteristic. The approaches and use of kriging methods proposed in the article allow to create maps with a given level of confidence and, accordingly, to take into account the risks caused by the uncertainty of measurements of radioactive contamination characteristics and uncertainty of their approximation.

Linear accelerators (Linac) are used in radiation therapy treatment and its technology improvement ensures high dosimetry quality that should be conserved for high radiotherapy efficiency. However, does the air gap between the exit window of Linac head and patient’s skin alters the physical properties of the photon beam? The objective of this study is to assess the physical properties changes of photon beam fluence according to air gap thickness under the Linac head. The air gap under the Linac head is the last material in the photon beam path; it induces alterations in the beam quality before reaching the patient’s skin. The Varian Clinac 2100 head and the air gap up to the phantom surface are modelled using Monte Carlo BEAMnrc code; the nominal beam energy is 6 MV. The BEAMDP code is used to extract the photon fluence. The photon beam fluence is affected by the air gap under Linac head and decreases by six times due to the photon beam attenuation with air gap thickness; in addition to increasing of beam contamination by scattered photons and electrons. Thus, the air gap induces the beam quality deterioration which is evaluated in terms of photon fluence with air gap thickness. To remove the particles contaminations and conserve integrally the photon beam quality, the number of the photon interactions with air atoms should be as low as possible under Linac head up to patient’s skin and ensure a higher quality of the radiotherapy treatment of deep tumour.

Authors: Estévez-Rionegro Noelia , Sampedro Mella María
Published: December 2020

The referred speech is usually presented by declarative verbs. However, there are other semantic classes specialized in speech reproduction procedures, such as request verbs. From the analysis of the Archivo de Textos Hispánicos de la Universidad de Santiago, made up of texts of oral, theatrical, journalistic and narrative language, we try to establish the frequency of use of the verbs implorar, suplicar, rogar, solicitar, pedir, reclamar and exigir as introducers of referred speech, as well as their greater or lesser productivity according to the type of procedure: indirect style, direct style, pseudo-direct style and hybrid style. In addition, the characteristics of each structure are explored with the proposal of knowing the configuration mode of the sequences that introduces each verb (its members, the position of each element, etc.) and that establish certain differences between them within each type of referred speech.
El desarrollo de la efectividad comunicativa escrita en ELE: las arabófonas a examen
Authors: Boillos Pereira Mari Mar
Published: December 2020

Communicative effectiveness in foreign language writing refers to the ability to dominate a multidimensional system that includes linguistic, sociolinguistic, and pragmatic knowledge. This work focuses on measuring the efficacy in Lebanese Spanish students’ writing throughout different stages. All students’ mother tongue is Arabic. For this purpose, a scale of measurement of communicative effectiveness has been applied in the texts written by 57 university students. The results attest an incidence of the level in the grammar domain, whereas this one does not seem to have an impact on the structure of the text, the recognition of the rhetorical situation or the selection of the ideas.
Who are the non-native speakers of English? A critical discourse analysis of global ELT textbooks
Authors: Rueda García Zulma Xiomara , Atienza Cerezo Encarna
Published: December 2020

As the demand for English language skills among non-native speakers globally has grown steadily so too has the number of ‘global textbooks’ for ELT aimed at a world market. Concurrently, critical perspectives of the expansion of English have begun to challenge the view that native speaker contexts ‘own’ English. Based on the aforementioned, and on reflective approaches to culture, our objective is to analyze critically the representations of speakers of English as a second or foreign language offered by two global ELT textbooks, to discuss the issues of essentialization and reproduction of stereotypes about the “non-native” speakers of English and their sociocultural characteristics in the constructed image. To achieve this purpose, we apply a methodology based on a sociocognitive approach to Critical Discourse Analysis (CDA) (Van Dijk, 2013), the concept of sociocultural knowledge as stated by the Common European Framework of Reference for Languages (CEFR), and critical perspectives of culture according to Holliday, Kullman, and Hyde (2004). Our findings indicate that, though the books include ‘non-native’ speakers in an attempt to address multiculturalism, their representation is generic, portraying a reified image of their sociocultural traits and presenting diversity mostly through national labels.

Identifying the expression of anger in a foreign language and reproducing it appropriately and precisely are skills whose relevance and lack of satisfying proposals have been pointed by research on the pedagogy of emotions (Dewaele, 2010; Toya & Kodis, 1996). This paper combines an identification of lacks in the pedagogy of emotional intonation with an analysis of spontaneous samples of anger as a basis to didactic guidelines for the introduction of the contextualized teaching of anger expression in Spanish. Through colloquial samples, key features for the expression of anger in Spanish are identified. A selection of technical features is adapted in an accessible didactic proposal that is conformed of the stages of identification, induction of recurrent patterns, guided and free production. The proposal offered here is a starting point for the design of didactic units on emotional and expressive speech, an area that lacks didactic guidelines.

Results of Theoretical Definition of Structural and Kinematic Parameters of Peeling Machine Working Elements
Authors: Anisimov Alexander V. , Rudik Feliks Ya.
Published: December 2020

Introduction. Peeling the moistened grains before grinding allows removing most of the outer shells with impurities on them from the grain surface. At the present time, the most commonly used machines for peeling are devices operating on the principle of “compression and friction”, in which the grains move along the friction surfaces of the working bodies. The aim of this study is to define and select structural and kinematic parameters of the machine working bodies, which would most effectively perform the process of peeling, and to make energy assessment of grain peeling.
Materials and Methods. To identify the dependence of the machine design and operating parameters on the inclination angle and punching angle of the sieve cylinder, a diagram of the movement of the grain along the inclined cylinder was drawn up using elements of the theory of the motion of material point on rough surfaces. The motion of grains on the cylinder surface is analyzed by the methods of analytical dynamics.
Results. The values of the geometric parameters of the particle position at point A are expressed as a function of the cylinder inclination angle α and the angle characterizing the shape of the inclined line of stamping of the cylinder β. Energy assessment of grain peeling process was made. With the radius of the sieve cylinder R0 = 0.135 m, the width of the working annular gap к = 0.01 m, the length of the cylinder L = 0.4 m, the horizontal arrangement of the cylinder, the angular velocity of the shaft ω = 90 rad/s, the angle of inclination of the stamping β = 22º, the calculated power was P = 4.5 kW.
Discussion and Conclusion. As a result of analyzing the motion trajectory of the grain located on the cylinder surface, there have been proposed the formulas relating the shape of the inclined punching line of the cylinder, characterized by the angle β, to the inclination angle α, the radius R0 of the cylinder, the shaft angular velocity and the grain frictional properties. The obtained analytical dependencies can be used for the approximate definition of the peeling machine design and kinematic parameters.

Published: December 2020

Introduction. The article deals with the problem of reducing the efforts when processing thin-walled bushings for hydraulic systems of agricultural machines with the ultrasonically activated cutting tool to achieve the specified processing accuracy and surface roughness of parts.
Materials and Methods. The article describes the technological standards for ultrasonic cutting. To assess the change in the tangential cutting force, a special device was developed to activate ultrasonically the tool for tangential cutting and corresponding experiments were carried out.
Results. An upgrading of a screw-cutting lathe equipped with a special device for ultrasonic cutting of low rigidity thin-walled parts is currently being carried out.

Published: December 2020

Introduction. The necessity to classify the state of rail lines affected by significant damaging factors on the sensitive element of the information sensor providing the assurance of classification quality with the required length of the rail lines of the control section forms the task of creating a classifier with extended functionality. Extending the functionality is possible using multidimensional state images with a set of informative features and training procedures for classification models. Using the classical classification principle with a single model leads to an excessive complication of the classification algorithm with low accuracy due to inaccurate solution of the system of conditional equations with multidimensional approximation by Hermite polynomials. Materials and Methods. The principles of reducing the dimension of the features space, various procedures for trainable classifier of state of rail lines with multidimensional patterns, the selection of decisive classification rules with a hierarchical grouping of classes, and the formation of a set of models of varying degrees of complexity trained to solve an incompatible system of equations are considered to solve the problem. There were obtained various degrees of complexity used in the adaptive algorithm for classifying the rail lines states using Hermite polynomials as models. Results. The article presents the results of developing 57 classifier models using Hermite polynomials with features of 2, 3, 4, 5, 6 arguments. As an example, the procedure of developing models with 2–6 features is shown. The research results showed that with an increase in the number of features, the quality of classification improves, as when dividing the state space into several classes. Discussion and Conclusion. The results of the studies confirm the feasibility of the principle of classification of rail line states by a set of classification models, and an algorithm of recursively increasing the classification complexity using a model of increased complexity. The criterion for presenting a new, more complex model is the mismatch between the results of the class calculation by the i-th model and the real class in which the rail line is located at the moment in time.
