Published: April 2023

The main objective of the present work was to evaluate the effect of culture through familiarity of wine technical experts on the perception of wine quality. A total of 32 wine experts from the United Kingdom and Spain undertook two sensory tasks with a total of 18 still white wines from these countries. The first assignment consisted in a descriptive task followed by a labelled free sorting task. The second assignment was a categorisation task in which experts had to classify the samples into groups based on five pre-established quality categories (ranging from very low to very high quality). Finally, experts evaluated their level of familiarity with the grape varieties employed. Results showed that grape variety was a key marker of the sensory profile of the evaluated wines. Wines made of the Albariño variety were described mainly as sour and as having a white fruit aroma, Verdejo wines were mainly sour and had fresh fruity aromas, the Bacchus variety was described as having floral aromas, and the Ortega wines as having oxidised, animal and defective aromas. In terms of perceived quality, leaving aside the wines of the Ortega variety, which showed an oxidation character resulting in the lowest quality scores according to both British and Spanish experts, it was observed that there is a clear effect of familiarity on the perception of quality. Spanish experts were significantly more familiar with Verdejo and Albariño varieties than with Bacchus, resulting in higher quality scores for Spanish varieties. In contrast, quality scores of the Bacchus wines and the wines produced from the two Spanish varieties were not significantly different in terms of quality according to the British experts, as were the familiarity scores reported by this group of experts. This work increases knowledge about the formation of quality perception and confirms the effect of familiarity on perceived quality among wine experts, highlighting the importance of cognitive factors in the construction of wine perception.

A precipitação destaca-se como a principal variável meteorológica no ciclo hidrológico, caracterizando a dinâmica dos ecossistemas terrestres e possuindo singular influência sobre ações e aspectos socioeconômicos. Dentro desse contexto, o objetivo deste estudo é investigar a ocorrência de possíveis tendências anuais dos dias de início, fim, duração e acumulado de precipitação, a partir de análises estatísticas, na estação chuvosa de Palmas – TO, para o período de 1995 a 2021. A análise de tendência foi obtida através de quatro testes estatísticos, um paramétrico (Regressão Linear) e três não-paramétricos (teste de Mann-Kendall, método de Sen’s e teste de Pettitt). Os resultados indicaram que a estação chuvosa de Palmas-TO está se encurtando (-1 dia/ano) - iniciando mais tarde (1,1 dias/ano) e finalizando mais cedo (-0,3 dias/ano), apresentando decréscimo no acumulado de precipitação (-14,5 mm/ano). As tendências anuais encontradas nesse estudo evidenciam as mudanças no comportamento da estação chuvosa de Palmas-TO, a qual está sob domínio do bioma Cerrado – considerado o berço de águas do Brasil.

Published: April 2023

<p>This study was conducted to describe aspects of the Nature of Science (NoS), its presentation, and its scores from chemistry textbooks used in Surakarta on acid-base equilibrium topics. This research was qualitative research with a content analysis method. Three high school chemistry textbooks for class XI from different publishers were analyzed by two raters based on ten aspects of the NoS. Interrater reliability was calculated using the cohen Kappa. The results showed that a scientific law is the only aspect that is not included in the three textbooks A, B, and C. Other aspects of NoS contained in textbooks A and B are slightly different from textbook C. Textbooks A and B contain the same aspects: empirical, inferential, creative, theory-driven, tentative, scientific methods, scientific theories, social science, and the application of science in socio-cultural, while textbook C does not contain tentative and theory-driven aspects. The implicit-correct category dominates the presentation of the NoS aspects in the textbooks. Presentations with implicit-incorrect and explicit-incorrect categories were not found in this study. The scores obtained by textbooks A, B, and C based on the presentation of aspects of NoS are 9, 11, and 8, respectively, of the maximum total score that can be obtained of 30. It did not show the presence of the NoS aspects explicitly, correctly, consistently, and completely, so textbooks containing NoS explicitly are required. Teachers also need to guide students in interpreting NoS in learning.</p><p><strong><em> </em></strong></p>

Numerical Inversion of the Sumudu Integral Transform in the Simulation of Electromagnetic Sounding of the Earth’s Interior
Authors: Epov M.I. , Nechaev О.V. , Glinskikh V.N. 
Published: April 2023

Abstract
—The integral Sumudu transform was established as an alternative to the Laplace transform in the 1990s. The Sumudu transform fundamental properties include preservation of the dimensionality of a function, ensuring measurement units both in the function and its image to be equivalent. Among its disadvantages is the absence of an explicit formula for calculating the inverse transform. The transforms are inverted by solving the corresponding Fredholm integral equation of the first kind, which is reduced to solving an ill-conditioned system of linear algebraic equations. We apply Tikhonov’s method for regularization of this type system. The paper proposes a technique for constructing a parametrized regularizing matrix that takes into account the properties of the Sumudu images obtained by modeling the electromagnetic sounding process of the Earth’s interior. A method for choosing the Tikhonov regularization parameters and the regularizing matrix is considered. The effectiveness of the proposed method for the Sumudu transform inversion is examined on a model problem of electromagnetic sounding of the Earth’s interior by a measurement system consisting of two loops spaced apart.
Phase Transformations in Feldspar Group Minerals with Paracelsian Topology under High Temperature and High Pressure
Authors: Gorelova L.A. 
Published: April 2023

Abstract—Feldspar group minerals (feldspars) form up to 60 vol.% of the Earth’s crust. The knowledge of their stability under extreme conditions (high-pressure and high-temperature) allow to better understand the processes, that occur in the subduction and collision processes. This review focuses on the behavior of feldspars with paracelsian topology (seven mineral species: three borosilicates, two aluminosilicates and two beryllophosphates) at elevated temperatures and pressures. Partly, new data on high-temperature behavior of paracelsian BaAl2Si2O8 (based on in situ high-temperature powder X-ray diffraction) provided. The high-temperature studies of 5 feldspar minerals with paracelsian topology (danburite, maleevite, pekovite, paracelsian, slawsonite) revealed that all of them are stable at least up to 800 °C. Among all of them only paracelsian undergoes polymorphic transition (at 930 °C), whereas all other minerals decompose or amorphisize. The structural deformations of these minerals demonstrate the different anisotropy degree upon heating, whereas the average volume expansion is similar for all of them (αV = 23 × 10–6 ºC–1). High-pressure behavior was studied for six of seven minerals with paracelsian topology (danburite, meleevite, pekovite, paracelsian, slawsonite, hurlbutite). The studied minerals undergo transformations with the stepwise increasing of coordination number of frame-forming cations from 4 to 5 and 6 upon compression The discovering of unusual structural units under extreme conditions (e.g., fivefold-coordinated polyhedral) can influence on the concentration and transport processes of trace elements that should be taken into account when interpreting geochemical and geophysical data. The crystal structure stability range of studied minerals highly depends on the chemical composition of frame-forming cations: aluminosilicates are the least stable and undergo the phase transitions below 6 GPa; borosilicates preserve their initial crystal structure up to ~20 GPa; beryllium phosphates do not undergo phase 2 transformations up to 75 GPa. It has been shown that transformations pathway of isostuctural compounds highly depends on the chemical composition of both extraframework and frame-forming cations that involves the difficulties with predictions of their behavior under extreme conditions.

Authors: Yaman Dr. M Aman 
Published: April 2023

ABSTRACTThe present study aims to determine the effect of fermented diet containing probiotics and digestive enzymes with different feed levels on growth, fat and cholesterol contents of broiler chickens. Evaluating the effectiveness of probiotics (P) and digestive enzymes (DE) in fermented diet on broiler was observed by 4 treatments: P0=control (fermented diet without P and ED) EP), P1(fermented diet contained 0.5% P only)), P2 (fermented diet contained 0.5% DE only), P3 (fermented diet contained 0.5% P and 1% DE) and P4 (fermented diet contained 1% P and 0.5% DE). A hundred DOCs of broiler chickens strain CP 707 were used (unsex) and it designed by a completely randomized design with 5 treatments, 4 replications and each replication consisted of 5 DOCs. The data obtained were analyzed by means of variance and Duncan's multiple range test. The results of present study showed that broiler fed on fermented diet containing P and/or ED with different levels had a significant effect (P0.05) on final body weight, weight gain, carcass weight, fat content on thigh muscle. Broiler fed on fermented diet contained 0.5% DE only (P2) resulted in better growth and weight gain than other treatments. However, fermented diet contained probiotics and digestive enzymes had no effect on fat and cholesterol contents in breast muscle. It was concluded that the addition of digestive enzymes in fermented diet formulated by local raw materials was very effective than probiotics in increasing body weight gain, carcass weight and prevented the increase in fat and cholesterol contents both in breast and thight muscles of broiler chicken.
GENETIC DIVERSITY OF IRAQI LOCAL GOAT BREEDS BY RAPD DNA MARKERS
Authors: Yousif Awat Nooradin , Abdalla Mohammed 
Published: April 2023

Genetic diversity of three Iraqi local goat breeds (Black, Hybrid, and Meriz) was studied by using random amplified polymorphic DNA (RAPD) markers. Fifteen primers were used, they generated a total of 259 amplification products, from which 142 bands were polymorphic, revealing 55.29% polymorphism. It was found that the mean value of Nei’s gene diversity (h) and Shannon's ınformation index (I) were 0.1778 and 0.2546, respectively. According to the analysis of genetic distances among breeds, the highest genetic distance recorded between Black and Hybrid 0.5108, while the lowest genetic distance recorded between Hybrid and Meriz 0.1431. The phylogenetic dendrogram based on Nei’s genetic distance analysis was in agreement with their phenotypic similarities in which the tree separated the surveyed breeds into two clusters, the first one including Black goat breed, and the second cluster includes Hybrid and Meriz breeds. These results indicated that Black goat breed is most genetically distant from both Hybrid and Meriz breeds. Finally, the moderate value for both of polymorphism and genetic diversity which obtained from the present study indicate that these breeds are genetically different, which provide a good background about these breeds for genetic improvement and conservation of our local goat breeds in the future.

This study aims to investigate the effect of the different concentration of RABAL (yeast and lactic acid bacteria) probiotics on the survival, feed conversion, growth and intestinal cells changes of tiger shrimp Penaeus monodon Fab. larvae. This study used a Completely Randomized Design (CRD) method with 4 treatments and 4 replications. Tiger shrimp with average size of 0.02 g was randomly stocked in each container containing RABAL with concentration of 0 ppm (A/control), 75 ppm (B), 150 ppm (C), and 225 ppm (D) with frequency once a day for 30 days. Data were analysed using one way ANOVA. The result showed that the application of RABAL with different doses into the shrimp culture media significantly influences (P0.05) the growth and food conversion ratio of tiger shrimp feed but did not significantly affect (P 0.05) on the survival rate. The value of water quality parameters in this study were still at normal levels for tiger shrimp rearing. As conclusion, the application of probiotics RABAL with different concentrations have positive effect on the absolute weight, absolute length, specific growth rate, feed conversion ratio and intestinal villi surface area of tiger shrimp larvae, without adverse effect on the survival rate of tiger shrimp seed.
