The Views of Greek Primary Education Teachers on the Formation of Cultural Identity
Authors: Vavitsas Theodoros , Sevi Athina A.
Published: March 2022

The aim of the present paper is to present the Greek Public Primary School teachers’ views on the construction of cultural identity as well as the role that the different collectivities play in modern societies. Exploring concepts such as “identity”, “diversity” and “cultural identity” and valorizing the theoretical framework of Habermas’ “Theory of Communicative Action”, the writers of this paper have applied the qualitative research of semi-structured interviews in order to collect their data. The participants were fifteen (15) Greek Public Primary School teachers while the questionnaire was comprised of thirty-two (32) questions. The findings indicate that: a) the teachers tried to define the meaning of “different identity” through the elements of otherness that arise from ethnic, linguistic and religious factors; b) the majority of teachers pointed out the religious aspect as the most important aspect of cultural identity; c) different ethnic groups necessarily have a different way of life, way of thinking or way of speaking; d) all teachers have unanimously stated that cultural differences are social constructs and not inherent in the members of a particular group; e) a person can move between different cultural identities; f) the majority of teachers argued that collective identities different from those of the dominant group should be preserved.

Authors: Gaudenyi Tivadar , Mihajlović Milan
Published: March 2022

The Carpathian Basin introduced in the geographical literature of the year 1921. However, after few clarifications it became in official use in 1947.  It has been used in the context of landscape unit or physico-geographical entity mainly by the Central European geoscientists.

The Carpathian Basin bordered by the Alps, the Carpathians, the Dinaric Mountains and Šumadija Mountains. It represents the lowlands (and mountains which they encircled) as well as the slopes of mountains which faced to the lowlands.

After numerous multidisciplinary analysis (surface geology and roughness, orography, slope angles) the area of the Carpathian Basin delineated and presented. The analysis shown that the Carpathian Basin excludes the intramontane basins in the Carpathians and the Dinaric Mountains.

Authors: Daya Audu M. , Haruna Ahmad I. , Maigari Abubakar S. , Yahuza Isah
Published: March 2022

Bauxites are normally formed from underlying aluminosilicate rocks as a result of tropical weathering. In our previous 2 papers, we presented the Geology, possible host, mineralogy, and geochemistry of the bauxites of Mambila Plateau, NE Nigeria. The bauxite was formed from residual chemical weathering of trachyte and occurs as a blanket cover over saprolite. XRD results showed gibbsite as the major mineral with small amounts of hematite, kaolinite, and quartz. Geochemistry of the bauxite ore is characterized by enriched Al2O3 (39.50-78.20.0%), erratic amounts of SiO2 (2.89-5.13%) and Fe2O3 (5.98-21.96%). In this study, the resources of Mambilla Bauxite Deposits (Block I and Block II) have been estimated to be 7,529,312.5 metric tons using block method of vertical geological cross-section bearing in mind that the Mambilla Bauxite Deposits have been explored by pitting on a regular grid pattern of 100 m×100 m. The bauxite deposit in Block II has met the requirement for metallurgical grade bauxite as standard specification (IS: 5953-1985, Reaffirmed [1]). While, Block I deposit has not met such specifications. Sustained investment in bauxite exploration is required to upgrade the ore reserves for sustainable development of a mining enterprise.

Technical efficiency in small and medium-sized firms in Mexico: A stochastic frontier analysis
Authors: Basurto Hernández Saúl , Sánchez Trujillo Gabriela
Published: March 2022

This paper examines the knowledge-technical efficiency (TE) association in small and medium-sized enterprises (SMEs) of manufacturing, trade, and service sectors. We use data from 2014 and 2017 reported by 28,034 SMEs in the National Survey on Productivity and Competitiveness of Micro, Small and Medium Enterprises (Encuesta Nacional sobre Productividad y Competitividad de las Micro, Pequeñas y Medianas Empresas, ENAPROCE) and the Stochastic Frontier Analysis (SFA). The main findings suggest that the average technical efficiency (ATE) of SMEs is 54.6%, SMEs show decreasing returns to scale, and SMEs with highly skilled workers -that transfer their technology less frequently and that use the Internet in their production processes- tend to have higher levels of TE. On the other hand, those firms that spend a higher proportion of their revenues on the process of paying taxes tend to be less efficient than others.
A note on fair threats and promises
Authors: Moreno-Okuno Alejandro Tatsuo
Published: March 2022

With their Sequential Reciprocity Equilibrium (SRE), Dufwenberg and Kirchsteiger (2004) developed a solution concept that incorporates reciprocity in sequential games. A SRE evaluates the kindness or unkindness of a strategy based purely on the actions it prescribes at the equilibrium path. However, given that it is not the objective of the SRE to evaluate threats and promises, it does not consider the actions outside the equilibrium path, where threats and promises are included. This article develops a new solution concept, Fair Threat Equilibria, which main objective is to give more reasonable predictions when threats and promises are included.
Land Records Modernisation in India: Himachal Pradesh
Authors: Mitra Sudeshna , Goswami Amlanjyoti , Jha Deepika , Sasidharan Sahil , Lushington Kaye , Wangchuk Tsomo
Published: March 2022

This work provides an institutional, legal and policy review of crucial aspects of land records modernisation systems in Himachal Pradesh. A state characterised by hilly terrain, high forest cover and low urbanisation, Himachal Pradesh provides useful lessons to understand the robustness and diversity of land record administration systems. The property regimes that have historically developed in the state include customary rights, common property resources, jointly held rights, and multiple other use and possession arrangements. There is a restriction on who can transact properties in the state, aimed at preventing alienation of land. Settlement operations are conducted every 40 years, and often take a long time to complete, but have led to relatively more up-to-date records than some other states. There are also concerns regarding the accuracy of spatial records, and data mismatches between textual and spatial components of the existing record versus the new technology led survey data if often is a cause of disputes.
Land Records Modernisation in India: Bihar

Published: March 2022

This work provides an institutional, legal and policy review of crucial aspects of land records modernisation systems in Bihar. The state’s progress with land records modernisation efforts has been historically slow but in the last few years, it has taken long strides in computerisation of land records and associated processes, and is on the way to a more accessible land information system. Bihar is a significant example to understand that in certain parts of India, issues of land and property ownership are embedded in socio-historical conditions, which can be addressed only in part by current modernisation efforts. The state is undertaking an attempt to address some of these issues through a resurvey, supported by large scale strengthening of capacity, and legislative framework. The ability of the state to address multiple claims in a judicious and timebound manner would determine, to a large extent, how successful these ongoing surveys and computerisation initiatives will be.

Alcoolismo em pacientes submetidos à cirurgia bariátrica: notas sobre a transferência da compulsão
Authors: Souza Antônio Augusto Mascarenhas de , Weber César Augusto Trinta
Published: March 2022

Introdução: Ao longo da vivência clínica psiquiátrica nos deparamos muito com pacientes que após o tratamento cirúrgico para a obesidade desenvolvem transtornos relacionados ao álcool.  Isso nos leva a questionar a existência ou não de um mecanismo de transferência da compulsão, o que antes era um transtorno alimentar passa a ser um transtorno aditivo. Objetivo: Investigar a associação do alcoolismo em pacientes submetidos à cirurgia bariátrica. Método: Revisão de literatura das produções científicas na modalidade textual de artigos, indexados na base de dados MEDLINE, por meio da ferramenta de busca livre PUBMED, realizada em junho de 2021, pelo uso das palavras-chave selecionadas segundo o Medical Subject Headings: alcoholism, bariatric surgery, substance use, drug use, addiction. Foram elegíveis 7 publicações para este estudo. Resultados: Os estudos revisados apresentaram resultados convergentes na associação entre pacientes submetidos à cirurgia bariátrica e alcoolismo. Ainda que as técnicas possam ser distintas, os transtornos relacionados ao álcool parecem estar mais relacionados à técnica de Bypass gástrico em Y de Roux. Conclusões: O alcoolismo em pacientes submetidos à cirurgia bariátrica está associado às complicações médicas pós-operatórias. Devemos levar em consideração a importância da necessidade de identificar os pacientes em risco de tais problemas, idealmente antes da cirurgia. Os dados revisados sugerem que tanto a cirurgia de Bypass gástrico em Y de Roux quanto o Sleeve gástrico, afetam dramaticamente a farmacocinética do álcool e causam uma provável transferência da compulsão (alimento X álcool) envolvendo o sistema de recompensa da via dopaminérgica mesolímbica. Devemos recomendar que os pacientes de alto risco ou pacientes com cirurgia de Bypass gástrico em Y de Roux) se abstenham do uso de álcool após a cirurgia bariátrica devido ao metabolismo alterado do álcool, bem como o potencial para transtornos por uso de álcool após a cirurgia.

Published: March 2022

En el presente trabajo de investigación se evaluaron las características morfológicas y el rendimiento de forraje verde de cuatro variedades de pasto de genero Pennisetum. Para ello, se realizaron dos evaluaciones con intervalos de corte de 45 días, distribuidos en un diseño completo al azar (DCA) unifactorial con sub-muestra con igual número de repeticiones e igual número de unidad de muestra. De acuerdo a nuestros resultados se encontró diferencias significativas (p < 0,05) entre las comparaciones de las medias las dos evaluaciones de las variables de altura de planta y grosor de tallo, excepto para las variables de número de macollos, largo y ancho de hoja (p < 0,05). Por otro lado, se observaron que durante la estación seca se retrasa el crecimiento de la planta y en consecuencia la deficiente producción de forraje. Sin embargo, para el pasto King grass verde es el que ha mostrado mayor resistencia a estas condiciones (sequía), el cual, se puede evidenciar en el rendimiento de forraje, sin embargo, no encontramos diferencias significativas (p < 0,05) entre cada evaluación. De acuerdo a nuestros resultados preliminares se concluye que cuanto más se incremente la edad de corte incrementará también el rendimiento forrajero de acuerdo a las condiciones ambientales presentadas localmente.

Published: March 2022

El cacao (Theobroma cacao L.) se cultiva en múltiples condiciones edáficas, fisiográficas y climáticas; y su zonificación adquiere importancia para la región Amazonas. Sin embargo, actualmente existe gran preocupación en la cadena comercial debido a la presencia de cadmio (Cd) en los productos derivados de cacao y en los suelos donde se cultiva. Por tanto, se revisaron 13 estudios que determinaron la presencia de Cd en suelo en Amazonas. De los cuales, se utilizaron valores de 104 registros georreferenciados de Cd y, mediante interpolación espacial, se generó un mapa de riesgo en Amazonas. Las concentraciones de Cd mostraron amplias variaciones, desde 0,05 a 3,54 mg/kg con una media de 1,56 mg/kg. Se determinó que el 39% del territorio de Amazonas se encuentra por sobre el límite tolerable para suelo agrícola (≥ 1,4 mg/kg), según la normatividad peruana (Estándares de Calidad Ambiental del Suelo). El mapa de Cd alerta sobre las zonas de alto riesgo para la zonificación agrícola en Amazonas. También se sugiere futuras investigaciones detalladas y sistemáticas de las concentraciones de Cd en suelos agrícolas de la región Amazonas, y el Perú, con un plan de muestreo acorde a la necesidad para la generación de predicciones mediante interpolaciones espaciales.
Optimized Cement Slurry Design for Controlling Water Influx in a Gulf of Suez Egypt Salt Dome

Published: March 2022

The Belayim Marine field, in the Gulf of Suez Egypt, presents many challenges to drilling operators. The most challenging section of the well is the 900-m, 16-in openhole containing a 13 5/8-in casing interval. The main risks in this section are the highly reactive salt layers in combination with high potential saltwater flow zones.

This interval is frequently drilled with a heavy 2.0-sg OBM to avoid saltwater influx during the drilling operations. Due to the mobility of the salt and unstable shale formations, the casing is run without centralizers to minimize the risks of not getting the casing to the desired section depth. Initially the interval was cemented using a 2.16-sg cement system with extended thickening time, both having the same 2.16-sg density. An external casing packer is used as an additional barrier in the event the cement placement does not achieve zonal isolation across the casing due to poor standoff.

After saltwater flow was observed at surface following the installation of the BOP, a detailed review of the casing and cementing design was performed to obtain a more robust procedure to avoid similar events in the future. Cement placement, operation design, and slurry properties were reviewed and optimized. The optimization was performed using details obtained from proprietary simulators as well as by optimizing the slurry properties in the laboratory. The cement operation design called for a single slurry scheme with very critical parameters, ensuring the cement will remain in the liquid phase to maintain applied pressure on the flow zone formations until the BOP is secured. The slurry design itself was revised and optimized in the laboratory providing right angle set along with good transition time to avoid any saltwater influx from formation fluids.

The optimized cement design and slurry properties have met all challenges. Furthermore, the new cement design in conjunction with the external casing packer succeeded in stopping the water flow influx and no similar events have occurred since the new cement operations design began being used in the field.

Published: March 2022

Objetivo: Revisar e analisar as principais características e técnicas empregadas pela Entomologia Forense. Revisão bibliográfica: A Entomologia Forense (EF) é uma ciência aplicada no âmbito judicial corroborando com a resolução de crimes. Para isso, é necessário o uso de métodos e ferramentas que auxiliam na determinação do Intervalo Pós Mortem (IPM) a partir de evidências entomológicas de insetos necrófagos. No Brasil os principais insetos de relevância entomológica são da Ordem Coleóptera e Díptera. O IPM precisa ser preciso, pois a partir dele se identifica e elimina suspeitos e ajuda na identificação de vítimas, portanto, as análises devem ser desenvolvidas de forma criteriosa, pois vários prejuízos podem ser acarretados à investigação, como a eliminação de fatos e evidências importantes para os processos judiciais. Os resultados oriundos das técnicas clássicas usados na determinação do IPM são complementados e validados com dados obtidos a partir de metodologias modernas de pesquisa de DNA. Considerações finais: A EF é uma área valiosíssima das ciências forenses, mas ainda é pouco difundida e necessita de investimentos para seu desenvolvimento técnico-científico.

Published: March 2022

В современной практике инженерных расчетов все более востребованным и повсеместным становится применение численных методик. В статье дается подробный обзор наиболее перспективной и все более востребованной модели грунтов модели упрочняющегося грунта (Hardening soil model (HSM)). Также приводится краткий обзор грунтовых моделей, которые до сих пор широко используются в отечественной практике инженерных расчетов с применением численных методов, модели, которые являлись предшествующими по отношению к модели HSM, на которых собственно, она основана. Изучение математических моделей грунтов в численных расчетах является залогом корректного применения компьютерных программ, залогом от бездумного нажимания клавиш компьютера, а значит залогом повышения надежности и безопасности строительства зданий и сооружений, а также повышения экономической эффективности проектов строительства.

These days structural as well as geotechnical tasks usually being solved with the help of numerical analytical technics. The practice of using analytical methods based on linearelastic behavior assumptions become less and less popular or even outdated. Huge growth of computer numerical power gives opportunity for development and application of advanced and complicated nonlinear mathematical soil models. Understanding basics of soil mechanics and the constitutive mathematical models describing soils behavior are crucial for correct usage of fi niteelements software and computer analysis of geotechnical everyday tasks. One of the most popular soil model used these days in engineering practice is the hardening soil model (HSM) proposed by T. Shanz in 1999. The article gives a thorough review of the development of HS model which is based on linear MohrCoulomb model and hyperbolic DuncanChang model.

Antibodies directed against GalNAc- and GlcNAc-O-Tyrosine posttranslational modifications – a new tool for glycoproteomic detection
Authors: Behren Sandra , Schorlemer Manuel , Schmidt Gudula , Aktories Klaus , Westerlind Ulrika
Published: March 2022

In the last decade, it was discovered that protein mucin-type O-glycosylation and O-GlcNAcylation modify Tyr residues besides the well explored Thr and Ser amino acids. Several glycoproteomic studies have identified α-GalNAc-O-Tyr modifications, and studies propose that β-GlcNAc-O-Tyr also exists as a new group of posttranslational modifications (PTMs). Specific bacterial toxins have further been identified to modify host GTPases with α-GlcNAc-O-Tyr top promote bacterial virulence. Despite being identified on numerous proteins, the biological roles, biosynthesis and expression of GalNAc- and GlcNAc-O-Tyr modifications are poorly understood. A major obstacle is the lack of tools to specifically detect and identify proteins containing these modifications. With this in mind, we prepared vaccine constructs and raised antibodies to enable selective detection of proteins carrying these new PTMs. The obtained polyclonal antibody sera were evaluated using ELISA and glycopeptide microarrays and were found to be highly selective for GlcNAc- and GalNAc-O-Tyr glycopeptides over the corresponding Ser- and Thr-modifications. For microarray analysis, synthetic GlcNAc- and GalNAc-O-Tyr Fmoc-amino acids were prepared and applied in Fmoc-SPPS to obtain an extensive O-glycopeptide library. After affinity purification, the antibodies were applied in western blot analysis and showed specific detection of α-GlcNAc-O-Tyr modified RhoA GTPase.

The Effect of Particle Size and Composition on the Optical and Electronic Properties of CdO and CdS Rocksalt Nanoparticles
Authors: Zwijnenburg Martijn
Published: March 2022

Quantum confinement like behaviour in CdO and CdS nanoparticles is demonstrated through explicit evGW-BSE many-body perturbation theory calculations on 0.6-1.4 nanometre particles of these materials. However, while the lowest optical excited-state, exciton, and the highest occupied and lowest unoccupied quasiparticle states in such nanoparticles are predicted to be delocalised, they are found to be delocalised over the surface of the particle only and not the whole particle volume. The electronic and optical properties of CdO and CdS rocksalt nanoparticles are predicted to differ dramatically from their structurally analogous MgO counterparts, where the lowest exciton and highest occupied and lowest unoccupied quasiparticle states are strongly localised, in contrast. This difference in behaviour between MgO and CdO/CdS is explained in terms of the more polarisable, less ionic, bonding in CdO and CdS. The effect on the optical and fundamental gaps of the particles due to the presence of amine capping agents on the particles’ surface is explored and predicted to be relatively small. However, the highest occupied and lowest unoccupied quasiparticle states are found to consistently shift to more shallow values when increasing the surface density of capping agents. An explanation of this shift, finally, is proposed in terms of the dipole field induced by the aligned dipoles of the capping agents.

Published: March 2022

Aim. To assess the relationship of psychoemotional changes with obesity in young men, depending on the age of manifestation of the disease and against the background of the program of weight loss.
Materials and methods. The study included 48 young men with obesity, aged 17 to 24 years. The subjects were divided into two groups. Group A consisted of 26 men with manifestation of obesity since childhood, group B 22 patients with onset of the disease from puberty. Subsequently, the study patients were subdivided depending on the type of obesity treatment (complex and non-pharmacological). The psychological status and anthropometric parameters were assessed on screening and after 12 weeks of treatment.
Results. Depressive disorders were initially observed in 40.9% of patients in group B and in 19.2% of patients in group A. In young men who underwent complex treatment of obesity, regardless of the time of manifestation of the disease, a clinically significant decrease in symptoms of depression was revealed. All types of eating behavior were revealed in the subjects, and these manifestations are more common in patients with manifestation of the disease since childhood. In group A, the restrained eating was in 50% of young men, external eating in 42.3%, and emotional eating in 30.7%. In group B, emotional eating in 9% of patients, external eating in 40.9%, and restrained eating in 31.8% of young obese men.
Conclusion. In the group of patients with manifestation of obesity since puberty, the frequency of depressive disorders was higher than in the group of young men with onset of obesity since childhood.
