In the broiler industry, the average daily gain and feed conversion ratio are extremely favorable, but the birds are beginning to approach the maximum of their genetic capacity. However, as a consequence of strong genetic selection, the occurrence of certain metabolic diseases, such as myopathies, ascites, sudden cardiac death and tibial dyschondroplasia, is increasing. These metabolic diseases can greatly affect the health status and welfare of birds, as well as the quality of meat. The main goal of this study was to investigate the changes in the main parameters of redox homeostasis during the rearing (1–42 days of age) of broilers with high genetic capacity, such as the concentrations of malondialdehyde, vitamin C, vitamin E, and reduced glutathione, the activities of glutathione peroxidase and glutathione reductase, and the inhibition rate of superoxide dismutase. Damage to the transsulfuration pathway during growth and the reason for changes in the level of homocysteine were investigated. Further, the parameters that can characterize the biochemical changes occurring in the birds were examined. Our study is the first characterize plasma albumin saturation. A method was developed to measure the levels of other small molecule thiol components of plasma. Changes in redox homeostasis induce increases in the concentrations of tumor necrosis factor alpha and inflammatory interleukins interleukin 2, interleukin 6 and interleukin 8 in broilers reared according to current large-scale husbandry technology and feeding protocols. A significant difference in all parameters tested was observed on the 21st day. The concentrations of cytokines and homocysteine increased, while the concentrations of glutathione and cysteine in the plasma decreased. Our findings suggest that observed changes in the abovementioned biochemical indices have a negative effect on poultry health.

INTRODUCTION:

Endoscopic sleeve gastroplasty (ESG) is safe and effective in patients with a body mass index (BMI) more than 30, with few cases reported in patients with overweight (BMI 27–30). However, evidence is lacking in the overweight group because the procedure is not currently performed routinely for such patients. In this study, we aim to evaluate the safety and efficacy of ESG in patients with a BMI between 27 and 30 who failed other weight loss modalities and/or had weight-related comorbidities.

METHODS:

This was a subgroup analysis of data pertaining to adults with a BMI between 27 and 30 who underwent ESG as a primary weight loss intervention. Data were abstracted from our longitudinal, prospective single-center registry. We analyzed weight loss, comorbidity resolution, adverse events, revisions, and quality of life using the Bariatric Analysis and Reporting Outcome System.

RESULTS:

Of 3,797 ESG procedures, 656 patients (17%) had a BMI of 27–30. The mean age was 33 ± 9 years and women comprised 94% (n = 616) of the sample. The mean % total weight loss at 6, 12, 24, and 36 months after ESG was 11.0 ± 7.2, 15.5 ± 6.3, 15.1 ± 8.3%, and 13.3 ± 9.9%, respectively. Eight of 22 patients with diabetes (36%) and 9 of 51 patients (18%) with hypertension experienced complete remission. Two patients were hospitalized with bleeding. Twenty-three patients (3.5%) underwent revision to laparoscopic sleeve gastrectomy or repeat ESG. Six more patients underwent suture removal. A total of 214 of 261 patients (82%) rated quality of life after ESG as good or better.

DISCUSSION:

ESG seems to be well tolerated, safe, and effective in patients with a BMI of 27–30.

Published: August 2023

Building dynamic partnerships between communities and academic institutions, via knowledge exchange, plays a vital role in generating research with mutual benefits for research partners and wider communities. Knowledge exchange between universities and schools has recently received particular interest in child and adolescent mental health research. This article outlines a knowledge exchange programme that involved children, primarily, and teachers and parents/carers in dialogues around school well-being. Using a series of co-created and multimodal creative activities, we: (1) worked closely with 25 students of an inclusive and multicultural primary school (aged 9 to 10 years old) to understand their school well-being experiences, and to co-create a school blog to communicate key messages with local communities; and (2) initiated a discussion around child and school well-being with a group of parents/carers and teachers through expanding on the children’s blog. In this article, we outline our methodology to facilitate children’s involvement with the project well-being activities. We explore key methodological strengths and challenges, and highlight lessons we learned and how these stress the significance of seeking young people’s points of view when designing school well-being initiatives.

Published: August 2023

O trabalho com a Língua Portuguesa, no contexto escolar, inicia-se nos Anos Iniciais do Ensino Fundamental, com professores cuja formação acadêmica não é obrigatoriamente na área de Letras, o que explica algumas dificuldades que esses profissionais possam vir a ter. Nessa perspectiva, partindo da hipótese de que os cursos de Pedagogia não dispõem de uma grade curricular que vise ao aprofundamento teórico de temas concernentes à língua(gem), objetivou-se, com esta pesquisa, investigar se e como é feito o tratamento da variação linguística em dez desses cursos ofertados por universidades públicas federais e estaduais das cinco regiões brasileiras, utilizando o aporte teórico da Sociolinguística Educacional (BORTONI-RICARDO, 2005) e de autores que versam sobre o contexto histórico do curso de Pedagogia no Brasil. Atinente à metodologia, realizou-se, sob uma abordagem qualitativa, o procedimento técnico da pesquisa documental, concebendo os Projetos Pedagógicos como objeto de estudo. A análise do material foi norteada por um roteiro composto por quatro perguntas, possibilitando auferir que os cursos, em sua maioria, não apresentam disciplinas voltadas à discussão sobre a variação linguística. Portanto, muitos pedagogos, em sua formação inicial, não adquirem os conhecimentos básicos para atender o que recomenda a BNCC a respeito deste tema.

Las transformaciones del cuerpo a lo largo de la historia y su influencia en el campo de la educación física
Authors: Adorni Mariano
Published: August 2023

Actualmente los profesores en Educación Física decimos adherir al constructivismo y a una concepción crítica y comprometida desde las teorías pedagógicas que enmarcan los procesos de enseñanza y aprendizaje. Solemos autodenominarnos como formadores de personas con sentido crítico y reflexivo, quienes hacen un uso consciente de su cuerpo. Profesores que dan un lugar central al alumno dejando de lado el protagonismo propio.

Pero al analizar nuestras prácticas surgen algunos interrogantes: ¿Es hoy día la Educación Física, la disciplina que decimos que es y que defendemos o los profesores en Educación Física seguimos siendo repetidores de “recetas” que los alumnos deben cumplir durante un tiempo determinado, con una repetición preestablecida y con un objetivo que muchas veces queda perdido? ¿Formamos personas con conocimiento y conciencia acerca de su propio cuerpo, o por el contrario formamos sujetos acríticos, enajenados, y al servicio de la sociedad capitalista donde se los cosifica, se los toma como instrumentos y solo son formados para responder al mercado del trabajo, al cumplimiento de horarios, a adoptar una conducta calma, respetar los tiempos y los lugares en pos de la producción?

Será entonces el objetivo de este articulo echar luz sobre esta problemática que atraviesa nuestro quehacer diario.
The Importance of Management Control by Responsibility Centres in SMEs: A Successful Case Study
Authors: Romana Fernando Acabado , Gestoso Carlos Guillen , Fernandez Silvia Gonzalez , Santos António Morais
Published: August 2023

This work was initially carried out with a survey on the importance of responsibility centers in small and medium-sized enterprises (SMEs). After some research I came across the fact that the literature is very focused on large companies, and not so much on SMEs. This fact is not directly proportional to reality, since 99.9% of companies are SMEs and only 0.01% are large companies. Having the possibility of obtaining an investigation in a specific case of an SME that did not use the management control by centers of responsibility, it was proposed to the administration to change the working methods, so that the analyzes were more real. For this, it was necessary to make a work planning, where all the area directors were involved, in order to obtain the results in a short space of time, it was also necessary to involve the Enterprise Resource Planning (ERP) partner, so that the system had properly programmed, with the new needs of the company.

A Critical Review on Properties of PCM-Incorporated Cementitious Building Materials
Authors: Das Rahul , Gandhi Indu Siva Ranjani , Palanisamy Muthukumar
Published: August 2023

Addressing the current global warming issues and carbon dioxide emission, the prime objective of the construction industry sector today is to develop energy-efficient environmentally friendly techniques to reduce thermal fluctuation inside buildings. Because phase change material (PCM) has good energy storage and release capacity, many researchers have shown interest in implementing PCM to increase thermal inertia of various building materials such as concrete, mortar, and gypsum board. PCM-incorporated building material is reported to reduce building energy consumption, shift peak energy demand, and reduce thermal swing, leading to improved thermal comfort inside the building. In addition to the aforementioned benefits, there are several other economic benefits and environmental benefits, as discussed in various sections in this paper. Although the use of PCM in buildings has a lot of advantages, it has some negative impacts on fresh state properties, mechanical behavior, and durability-related properties of building materials. However, it is to be noted that the extent of negative impact is dependent on the type of PCM, incorporation technique, dosage of PCM, and encapsulation material, which are also critically reviewed in this paper. To summarize, this paper provides a systematic classification of the literature on PCM in building materials in terms of properties of different types of PCM; PCM incorporation methods; effect of PCM on fresh state, mechanical, durability, and thermal properties of concrete; and various benefits of PCM. This paper also provides structured insight into various issues that hamper PCM’s robustness and commercial viability in buildings. Furthermore, challenges and recommendations are provided by summarizing the significant research gaps from the literature.
Experimental Study on Sliding at the Soil-Structure Interface of a Shallow Foundation

Published: August 2023

The interaction between a foundation and its supporting soil involves several different energy dissipation mechanisms. For example, sliding of a foundation element is a soil-structure interaction component that can alter the seismic demand on a foundation as well as its superstructure. Experimental data from tests with realistic boundary and stress conditions is required to characterize the frictional properties at the soil-foundation interfaces in order to model sliding of shallow foundations. To this end, a series of large-scale monotonic laboratory shear tests were performed to study the interface between a shallow concrete foundation element and Ottawa F-55 sand under varying normal pressures, shearing rates, and foundation surface roughnesses and textures. The soil-foundation interface behavior was evaluated through a combination of global measurements of force and displacement, as well as by capturing the localized effects around the interface. This article describes the dependency of the interface behavior on each of the aforementioned variables. The results indicate that when subrounded fine sand comes into contact with surfaces of varying roughness, it exhibits different shear resistance behaviors. The findings further reveal insights into the dependency of the interface frictional characteristics and shear failure zone on the real area of contact, which includes irregularities on the surface. The data further utilized to study the impact of adopting different interface friction assumptions on the finite element model’s interface shear response being subjected to monotonic loading. Using the internal friction angle, or a factored down value, as an estimation for interface friction may lead to an erroneous or unconservative prediction of the superstructure response.
Compaction Characteristics of Organo-silane Treated Soils

Published: August 2023

The extent to which hydrophobic soils can be used in geotechnical engineering practice depends upon a commensurately increased understanding of how fundamental relationships apply in hydrophobic systems, such as moisture-density. This research is to determine the compaction characteristics of organo-silane (OS) treated soils using conventional geotechnical laboratory equipment. The intrinsic difficulty in lubricating hydrophobic soils, which would allow for rearrangement of particles and subsequent compaction, arises from their inherent low surface energy. This work describes a method for compacting OS treated soils that leverages the necessary conditions such as reaction time and drying conditions for achieving hydrophobicity. Procedural steps for compacting OS treated soils are detailed by making use of a water-soluble hydrophobizing agent added to a fine-grained soil. Based on the critical dosage ratio of 1:100 (hydrophobizing agent: soil) identified, a molding water content is defined constituting of a fraction of the hydrophobizing agent. Soil water content and dry density curves are developed using the standard Proctor and Harvard miniature to contrast the resulting effect of OS. Compared to the untreated soil, a decrease in optimum water content was observed with the OS treated soil regardless of compaction technique used. For the standard Proctor test, a decrease in optimum water content from 12.0 to 9.2 % was observed, whereas compaction with the Harvard miniature showed a marginal decrease from 9.3 to 9.0 %. With the untreated soil, a relatively larger maximum dry density (2.17 g/cm3) was obtained with the standard Proctor compared to the Harvard miniature (2.05 g/cm3). The protocol defined to compact OS treated soils has shown to induce hydrophobicity spatially within the sample depth. These results suggest that engineered water repellency can be implemented in so far as treatment and compaction are largely synchronous and prior to reaction and hydrophobization.
The Effect of Rice Husk on the Variability of Physical and Mechanical Properties of Composites
Authors: Mendes Maria Paula , Raimundo Ana , Bimbati Marina , Nogueira Rita , Flores-Colen Inês , de Brito Jorge
Published: August 2023

Rice husk (RH) is one of the most commonly grown and consumed cereals in the world. Because of its low nutritional value, it is not commonly used as a food or fertilizer. Instead, it is often burned or landfilled. To develop RH-based composites for thermal and acoustic nonstructural applications, a balance between achieving satisfactory performance in physical and mechanical properties is essential as well as ensuring reliability and predictability in the behavior of the composites. The inclusion of RH in composites can result in increased variability in their performance because of the husk’s elastic behavior during compaction and its hydrophilic properties. The RH used in the study was collected from Baixo Mondego, Portugal, and approximately 90 % of the particles had sizes ranging from 1 to 4 mm. To reduce cement usage, different mixtures were produced and categorized based on the use of two types of cement, varying percentages of limestone filler, and different quantities of RH. Robust descriptive and inferential statistics (Student’s t-test and Mann–Whitney U test) were employed to analyze the variability of physical and mechanical properties in 10 different RH-based composites. A study was conducted to assess whether a specific mixture formula within a given group exhibited consistent behavior across different batches or yielded intrinsically different results. This helps to identify the key adaptations required in the industrial process of incorporating this biomaterial into composites. The results have shown that it is possible to produce RH-based composites with less variability of performance and potential for nonstructural applications. In this case, cement CEMI/A-L 42.5 R type with limestone filler addition and paste-to-RH ratio by volume between 1.54 and 2.22 was the most sustainable mix design because it had a small variability of results and reduced the cement content.
Search for ways to integrate elements of the scientific knowledge into the educational process of Sunday schools
Authors: Urbanovich Liubov
Published: August 2023

The present article attempts to answer the question of the possibility and pedagogical expediency of harmonizing religious and natural science knowledge in the classroom within the framework of the parish education of children. For quite a long time, natural science knowledge was used as a powerful means of atheistic propaganda and destruction of any thought about faith and religion among the people. At present, there remain difficulties in combining scientific knowledge and religious faith in science and educational practice. As a result of the materialistic approach to teaching natural science subjects at school, the young believers reject the biblical picture of the world offered in Sunday School as contradicting scientific knowledge and suffer from ideological dualism.The purpose of the present work is to substantiate the necessity and value of integrating elements of natural science knowledge into the educational process of Sunday School through effective ways of its implementation. The article reveals the theoretical aspects of the indicated problem and describes practical methods of integrating natural science knowledge into religious education within the framework of parish activity. Such forms of integration as natural science laboratories of a young naturalist, master classes, creative workshops and others are singled out as the most efficient. Basing on the available practical experience, the article presents the real and expected educational effects and highlights the pedagogical conditions that contribute to their achievement.The author expresses the hope that due to the integration of elements of natural science knowledge into the religious education of children, it will be possible to avoid the ideological and religious crisis among teenage schoolchildren and reduce the number of children who abandon the faith planted by parents and teachers and leave the confines of the church.
Bloqueos supraescapular e interescalénico como analgesia después de la reparación artroscópica del manguito rotador: estudio de cohorte comparativo retrospectivo
Authors: Rojas Lievano Jorge , Salas Mercedes , Salas Corina , Suarez Ana María , Fierro Guido , González Juan Carlos
Published: August 2023

Introducción: El objetivo de este estudio fue comparar la eficacia de los bloqueos interescalénico y supraescapular, solos y combinados, como analgesia posoperatoria en las primeras 3 horas tras la reparación artroscópica del manguito rotador.

Materiales y Métodos: Estudio de cohorte comparativo retrospectivo, realizado entre 2019 y 2021. El criterio de valoración principal fue el puntaje del dolor de hombro en la sala de recuperación evaluado con una escala analógica visual por el paciente. Los criterios de valoración secundarios fueron el consumo de opioides en la sala de recuperación y las complicaciones de la anestesia locorregional.

Resultados: Se incluyó a 175 pacientes, 13 en el grupo de bloqueo interescalénico, 61 en el grupo de bloqueos interescalénico más supraescapular y 101 en el grupo de bloqueo supraescapular. Los grupos de bloqueo interescalénico y de bloqueo interescalénico más supraescapular tuvieron significativamente menos dolor en la sala de recuperación y una tasa total menor de opioides consumidos en miligramos equivalentes de morfina que el grupo de bloqueo supraescapular (p = 0,001 y p <0,01, respectivamente). No hubo diferencias significativas en el dolor ni el consumo de opioides entre el bloqueo interescalénico solo ocombinado con bloqueo supraescapular.

Conclusiones: El bloqueo interescalénico fue más eficaz que el bloqueo supraescapular para aliviar el dolor y disminuir el consumo de opioides en la sala de recuperación tras la reparación artroscópica del manguito rotador. La combinación de bloqueo interescalénico más bloqueo supraescapular no resultó en un incremento de la eficacia, y se sugiere no combinar estas dos técnicas.

Published: August 2023

La escápula alada suele producirse por lesiones neurológicas tanto del nervio espinal como del nervio torácico largo. La aparición a causa de un tumor ventral de la escápula dificulta su diagnóstico inicial. Presentamos el caso de una mujer joven, con limitación para la rotación externa del hombro, sin antecedentes traumáticos conocidos, evolución progresiva e imagen compatible con una lesión de partes blandas dependiente de la aponeurosis del músculo subescapular confirmada por biopsia como un tumordesmoide. Aunque se trata de un tumor benigno y autolimitado, tiene una inquietante alta tasa de recidivas después de la resección, por lo que se dispone de numerosos tratamientos y muchos grupos optan por hacer un seguimiento médico estrecho de los factores pronósticos y las limitaciones funcionales del paciente, con lo que obtienen resultados satisfactorios y, en algunas series, superiores a los del tratamiento quirúrgico.

Early Bidialectal Maintenance among Chinese Heritage Learners in Canada
Authors: Li Guofang , Shen Senyao
Published: August 2023

Research on Chinese heritage-language maintenance has predominantly focused on Mandarin as the default mother tongue and has largely ignored learners’ dialects or language varieties. As a result, we know little about dialect speakers’ beliefs and practices of maintaining their language varieties other than Mandarin, particularly in the home domain. Using family language policy (FLP) as the theoretical framework, this multiple case study examined six Chinese families’ beliefs and practices in early bidialectal (Mandarin and dialect) maintenance over three years when their children moved through kindergarten to Grade 3. Findings indicated that parents subscribed to the dominant language ideologies and placed their dialects at the bottom of the language hierarchy. However, the parents differed in their beliefs in the value of their dialects; and families who celebrated bidialectalism actively maintained their dialects while those who did not gradually gave up on passing their dialects to their children, even when grandparents were involved in the maintenance efforts. The findings have important implications for supporting and achieving bidialectalism in immigrant countries.
Language and the Miracle Creed

Since Massimo Piattelli-Palmarini’s coining of the term biolinguistics in 1974, biolinguistics research has attracted numerous attentions from the linguistic circle and its neighbouring fields, triggering various ways of pursuing it. The current paper makes clear the origin, significance, and implications of biolinguistics, especially, the reason why the biolinguistics enterprise realizes the miracle creed firstly assumed by Albert Einstein. In this way, the controversies and mis-conceptualization of biolinguistics in current linguistic literature can be clarified, paving the solid foundation for future biolinguistics research.
Internal 'Wh'-Thought and External 'Wh'-Expressions
Authors: Chunyan Ning
Published: August 2023

This article attempts to challenge the model in which a universal wh-thought as represented in LF/SEM is derived from grammatical wh-expressions, and further proposes a model with a prelinguistic Conceptual-Intensional Interface, where wh-thoughts are generated in-language a priori to their externalization into grammatical or ungrammatical wh-expressions, in conformity with Chomsky’s proposal of separating thought from expressions and his dictum of ‘meaning with sound’ rather than ‘sound with meaning’. The article also highlights how the saltation from animal cognition to human cognition makes Merge workable to yield Conceptual Hierarchic Structure for internal wh-thought.
COMO MUDAM INSTITUIÇÕES E POLÍTICAS? INSTITUIÇÕES COMO MECANISMO DE MUDANÇAS ENDÓGENAS

Published: August 2023

O modelo de mudança endógena de Mahoney e Thelen representou um aporte significativo ao desafio posto à agenda de investigações sobre câmbio de instituições e políticas públicas. Contudo, para conferir-lhe maior consistência, é preciso (1) incorporar rupturas pontuadas e conferir-lhes explicação institucionalmente endógena; (2) incorporar dimensão positiva e de inovação no status quo à ação de instituições políticas, decorrente de sua capacidade estatal e poder de agenda; (3) focar nos ativos dos agentes e sua capacidade em promover coalizões políticas e, finalmente, (4) interpretar reformas por layering como resultantes de estrutura de oportunidades que combina elevados pontos de veto com espaços institucionais e graus de discricionariedade para negociação entre autoridades e agentes extra estatais. Um modelo de mudanças institucionais endógenas sob estas coordenadas pode contribuir substituindo a fluidez no emprego de categorias analíticas por mecanismos institucionais, bem como deslocar o foco dos estudos sobre agenda política, de issues para processos e decisões institucionais.
Fabrication process optimization of nHA–CNTs-reinforced PEEK hybrid nanocomposite
Authors: Kumar Manjeet , Kumar Rajesh , Kumar Sandeep
Published: August 2023

Compression molding is the leading fabrication process for polymer composites. The settings of process parameters highly influence the mechanical properties of composites. This study optimized the ball-mixing and compression-molding process parameters for the fabrication of hybrid nanocomposites based on polyetheretherketone (PEEK), multiwalled carbon nanotubes (MWCNTs) and nano-hydroxyapatite using the Taguchi method. The elastic modulus examined using the nanoindentation method of static mechanical analysis was taken as the output response variable. The optimum levels of mixing time, mold temperature, mold pressure and holding time process parameters for the maximum elastic modulus were found to be 90 min, 400°C, 150 bar and 15 min, respectively. The analysis of variance technique showed that the mold temperature had the highest contribution (46.82%) in enhancing the elastic modulus to the largest value. The elastic modulus and hardness of the PEEK-based hybrid nanocomposite with 30 wt.% nHA and 3 wt.% MWCNTs were observed to be 83 and 65% higher than those of pure PEEK, respectively. The hydrophilicity of PEEK was improved with the reinforcement of nHA, attributed to the presence of oxygen-containing functional groups in the chemical structure of nHA.
A LABORATORY SCALE INVESTIGATION OF MANNING ROUGHNESS COEFFICIENT IN OPEN CHANNEL BED WITH DIFFERENT GRAIN SIZE AND SLOPES

Published: August 2023

Efforts for getting the maximum efficiency from the existing water resources and to implement new projects are getting more attention these days. Determining the flow resistance for the project design and control process in open channels requires sophisticated applications. It is usually essential to be aware of the characteristics of the channel and flow to determine the hydraulic roughness, which represents the resistance of the flow. Hence, empirical calculation and evaluation of the hydraulic roughness will support future design and planning processes. In this study, four different particle sizes (d50= 28mm, 17.5mm, 4mm, and 1.75mm) that were fixed on blocks were used. These particle sizes were then used as the bed covering together with, three different horizontal bed slopes, and flow rates in the experiments to determine the associated Manning roughness, n. During the experiment, Froude number values were examined and it was determined that, in 32 experiments the flow regime can be considered as subcritical. Alternatively, the Lotter method was used to confirm the roughness values obtained by the Manning equation. It was concluded that the roughness values obtained by the selected methods have good concordance with each other.

Cardiovascular diseases (CVDs) remain the leading cause of morbidity worldwide. The heart sound signal or phonocardiogram (PCG) is the most simple, low-cost, and effective tool to assist physicians in diagnosing CVDs. Advances in signal processing and machine learning have motivated the design of computer-aided systems for heart illness detection based only on the PCG. The objective of this work is to compare the effects of using spectral and sparse features for a classification scheme to detect the presence/absence of a pathological state in a heart sound signal, more specifically, sparse representations using Matching Pursuit with multiscale Gabor time-frequency dictionaries, linear prediction coding, and Mel-frequency cepstral coefficients. This work compares the performance of PCGs classification applying features as a result of averaging the samples or the features for each PCG sound event when feeding a random forest (RF) classifier. For data balancing, random under-sampling and synthetic minority oversampling (SMOTE) methods were applied. Furthermore, we compare the Correlation Feature Selection (CFS) and Information Gain (IG) for the dimensionality reduction. The findings show a SE=93.17 %, SP=84.32 % and ACC=85.9 % when joining MP+LPC+MFCC features set with an AUC=0.969 showing that these features are promising to be used in heart sounds anomaly detection schemes.

The Mediterranean basin is regarded as one of the most affected global regions by climate change. Traditionally, viticulture in this region copes with high temperatures, heat waves and drought. Such extreme conditions are expected to intensify due to climate change in the future. Our study focuses on the viticulture of Santorini Island, located in South Aegean (Greece). Local varieties trained with the traditional ‘Kouloura’ training system have been cultivated for thousands of years on the island, producing recognised high-quality PDO wines worldwide. The literature on these traditional training systems is scarce, and their investigation could aid in the adaptation of viticulture to hotter and drier future climatic conditions. The objective of this study was to compare the physiological and agronomic response of Assyrtiko grapevines to the traditional training systems ‘Kouloura’ and VSP training system over two growing seasons and to establish the factors influencing the performance of each system in the semi-arid conditions of Santorini Island. In brief, the ‘Kouloura’ training system maintained a less-stressed water status compared to VSP, while for both studied years during ‘Kouloura’ exhibited significantly higher photosynthetic rates and stomatal conductance. Regarding microclimate observations, we found that, especially during heatwaves, VSP’s grapes were more exposed to higher temperatures during midday than ‘Kouloura’ and that the ‘Kouloura’ system protected against damage from heatwaves and strong winds when compared to VSP. Investigating the mechanisms by which these traditional training systems are adapted to hot, dry climatic conditions creates applicable knowledge for developing and using alternative training systems in similar environments to adapt to climate change.
Developed Method. Interactions and Their Quantum Picture
Authors: Ogonowski Piotr
Published: August 2023

By developing the previously proposed method of combining continuum mechanics with Einstein Field Equations, it has been shown that the classic relativistic description, curvilinear description, and quantum description of the physical system may be reconciled. For a system with an electromagnetic field, the Lagrangian density equal to the invariant of the electromagnetic field was obtained, vanishing four-divergence of canonical four-momentum appears to be consequence of the Poyinting theorem, and explicit form of one of gauges of the electromagnetic four-potential was introduced. The proposed method allows for further development with additional fields.

In the field of clinical medicine, the real-time monitoring of carbon dioxide gas exhaled by the human body is of great significance. At present, the detection devices in the market are mainly detected by sucking a small amount of gas in the nasal cavity to the detection device, and there are some problems such as too long sampling tubes, easy blockage or distortion, and abnormal gas dispersion. In this paper, a micro-nano optical fiber sensor that can directly detect the concentration of end-tidal carbon dioxide is proposed. The measurement is achieved by using the principle of high evanescent field absorption, and the operating band is 2.004 μm. The sensor uses micro-nano optical fiber as the sensing area, and then detects the presence of carbon dioxide gas exhaled by human body through optical power attenuation. The function of micro-nano fiber is to realize the transmission of signal light and also serve as the absorption medium of the gas to be measured. In addition, the variation of light power also reflects the respiratory cycle of the human body. The sensor can realize rapid real-time response to carbon dioxide gas detection, with small size, low cost, and easy to replace. It has great application potential in clinical scenarios such as Gastrointestinal Endoscopes that require real-time monitoring of human respiration.

Time Reversal Symmetry Broken Floquet State of SMB_6 - A Strong Topological Insulator
Authors: Tyagi Udai Prakash , Goswami Partha
Published: August 2023

We show that the compound samarium hexaboride is a strong topological insulator using the eigenvalues of the space inversion operator in the low-energy limit of the periodic Anderson model. Additionally, we assume the presence of the ferromagnetic exchange interaction (M). A Dirac cone like feature in the surface state energy spectra is observed for M equals zero in a certain parameter range. For M not equal to zero, there is no Kramers degeneracy. We have been able to show that this phase corresponds to the quantum anomalous Hall state by calculating Berry curvature and the Chern number. Using Floquet theory, we further show that the access to a novel state with broken time reversal symmetry is possible due to the normal incidence of circularly polarized optical field on the surface of the compound despite M being absent.

This article examines evolution of trans-regional Ethio-Djibouti railway corridor and its impact on urbanization. Exploratory and descriptive research methods were employed to examine the impact of this railway corridor. Case study also applied to examine eight selected intermediate cities. The article points out that, the Ethio-Djibouti railway corridor conceived different kinds of linear urban centers ranging from small towns to intermediate cities around stations. Those urban centers have been attracting industries along their fringes that leads to rural urban continuum ribbon urbanization. As the old railway line deteriorated, these linear urban centers on the railway corridor had also been declining from time to time. In 2011 new project was started to construct the Ethi-Djibouti standard gauge railway parallel to the old railway line. This new standard gauge railway infrastructure adopts ‘peripheral station’ development approach, which provides a room for width expansion for station based urban centers. It also attracts industries in a form of special economic zones, which causes for labour migration from rural and nearby small urban centers that caused rural-urban continuum of ribbon settlement; strengthen trade gate way for the landlocked Ethiopia that caused trans-regional integration.

Abstract: The traditional model of closed circuit ball milling systems has been used for several decades, however, if the classifier of the closed circuit ball mill system performs the duties of both pre-classification and check-classification, the characterization error of the traditional model is large. To address this problem, a new model is obtained by modifying and supplementing the traditional one. The most important feature of the new model compared to the traditional model is that the circulating load is considered to be the fresh feed for the entire system rather than the ball mill. The error between the slurry level height calculated using the traditional model and the actual is 52.31%, which is 13.77 times higher than that of the new model. When the relative capacity varies greatly, that of the ball mill calculated by the traditional model fluctuates between 0.95 and 1.15, while the new model is 0.6 to 1.4. The new model has a higher accuracy than the traditional model in characterizing the production status of the grinding system, which is of some significance for industrial production.

» Approximately 1 in 3 high-impact athletes develops patellar tendinopathy (PT), with the proximal insertion of the patellar tendon being the most commonly affected anatomical site.

» Nonoperative treatment options are effective in reducing pain and restoring functionality in most patients with PT. However, operative intervention should be considered when conservative management fails.

» A comprehensive review of the literature on surgical procedures, including both open and arthroscopic approaches, was conducted with a specific focus on clinical outcomes and return to sports.

» Both open surgery and arthroscopic surgery for PT have demonstrated favorable success rates and return-to-sport outcomes, with arthroscopic treatment potentially expediting the recovery process.
