Protestos de junho de 2013: a construção do processo de impeachment de 2016 pela revista Veja
Authors: Pimenta Rosângela Oliveira Cruz , Aguiar de Oliveira Cavalcante Maria do Socorro
Published: March 2024

Este artigo trata sobre a relação entre a imprensa brasileira e a construção do processo de impeachment de 2016. Nosso objeto de estudo são as reportagens sobre os protestos de junho de 2013 da revista Veja. Temos como objetivo mostrar como a revista analisada inaugura no imaginário popular uma relação entre as manifestações e o impeachment da presidenta Dilma Rousseff. Nosso referencial teórico são os estudos de Bakhtin/Volochinov (1999); Pêcheux (1990, 1999, 2009, 2011, 2013); Orlandi (1983, 1993, 1996, 2001, 2005, 2011), Bobbio (2011); Courtine (2006, 2009), entre outros. A análise permitiu-nos perceber que o discurso das reportagens da revista Veja é parcial, relacionando a insatisfação com o governo do PT aos protestos ocorridos em junho de 2013, contribuindo para fomentar um clima popular para o impeachment, por meio de um golpe político em 2016.
O discurso da precarização do trabalho no governo Bolsonaro: ultraneoliberalismo e a destruição das bases de proteção social do Estado
Authors: Guimarães da Rocha Andre Luis , Aguiar de Oliveira Cavalcante Maria do Socorro
Published: March 2024

Este trabalho analisa o discurso sobre os direitos trabalhistas materializado em propostas do governo Bolsonaro. Objetiva contribuir para o desvelamento da ideologia que sustenta tal discurso e os silenciamentos nele contidos, identificando as consequências de tais propostas para o trabalhador e o contexto amplo e restrito que possibilita que um discurso dessa natureza possa ser produzido e ainda tenha a adesão da classe trabalhadora. Num contexto amplo de crise estrutural do capital, de insurgência de ideais neoliberais como solução e sublevação de uma extrema direita; reestruturação produtiva do capital através do paradigma toyotista; 4º Revolução Industrial e uberização do trabalho e num contexto restrito de fracasso da política de conciliação de classes; golpe parlamentar e judicial; aceleração de políticas neoliberais ascende um discurso que subsume a ideologia ultraneoliberal, atuando sob o engodo da “ordem, da moral, dos bons costumes e do caminho da prosperidade econômica”. Com o intuito de atingir nosso intento, debruçamo-nos nos pressupostos teóricos da Análise do Discurso de perspectiva materialista-histórica. A partir de uma pesquisa de natureza discursiva, evidenciamos o funcionamento da ideologia ultraneoliberal, destruindo as bases de proteção social do Estado, tornando o trabalhador mais vulnerável ao processo de exploração de sua força de trabalho.
O Talibã e a educação da mulher afegã: uma forma de silêncio, denúncia e resistência
Authors: Lopes Maraisa , Da Silva Santos Francisca Mônica
Published: March 2024

Objetivamos analisar os efeitos de sentido produzidos em uma postagem no Instagram composta por uma fotomontagem, acompanhada de um enunciado, que retrata a ameaça aos direitos educacionais das mulheres afegãs. Em específico, analisar e descrever o funcionamento discursivo dessa ameaça como forma de silenciamento e, do mesmo modo, analisar como a luta pelos direitos estudantis da mulher afegã tem sido uma forma de denúncia e resistência, textualizada, principalmente, por meio da materialidade não-verbal. Para tanto, o arquivo corresponde a uma fotomontagem circulada no Instagram no momento de (re)ocupação pelo Talibã no Afeganistão. A análise foi realizada com base nos pressupostos teóricos da Análise de Discurso Materialista, sob os trabalhos de Pêcheux (1995), Orlandi (2005; 2007; 2020), Modesto (2015), Neckel (2015) e Souza (1997). Com a análise, observamos como a educação feminina afegã, significada na fotomontagem, sofre determinações próprias do autoritarismo, silenciando esse público. No entanto, pelo contexto imediato, notamos movimentos de resistência e denúncia funcionando de modo concomitante. Portanto, ainda que seja uma montagem de uma fotografia, os elementos que diferenciam a fotomontagem de sua versão origem significam de algum modo e vão desencadear efeitos de sentidos outros, mas que estão relacionados em algum ponto com a produção originária.

ESG como a nova cara do capitalismo
Authors: Alves Rodrigues Eduardo , Agustini Cármen
Published: March 2024

Ante certa força designada "o imperativo das questões ambientais", apresenta-se uma diretiva caucionada na metáfora "a nova cara do capitalismo", em circulação na sociedade de mercado desde o início dos anos 2000. A essa metáfora é atribuída a identidade dada pela sigla ESG (Environmental, Social and Governance, em inglês). A partir dessa conjuntura significativa do modo de produção dominante mundialmente, objetivamos compreender, neste trabalho, como o capitalismo é significado na e pela formação discursiva ESG, considerando a articulação discursiva entre capitalismo e sustentabilidade uma de suas bases fundantes. Para tanto, inscrevemos esse questionamento no quadro teórico-metodológico da Análise de Discurso, buscando tornar legível/visível como a referida articulação deriva em outras articulações e latitudes discursivas, por meio das quais torna-se possível a suspensão da evidência segundo a qual o capitalismo funcionaria diferentemente ao absorver tal articulação. Esse questionamento ganha contornos pela análise de recortes produzidos sobre o número especial da MIT Technology Review e da seção do Blog Nubank, ambos dedicados a textualizar a discursividade ESG, e, em decorrência disso, a (re)atualizar a contradição entre o fundamento do capitalismo (a obtenção do resultado/lucro a todo custo) e a sustentabilidade da vida social e ambiental.

Thime Between the diagnosis and treatment of esophagus cancer
Authors: Souza Ana Silvia Santos
Published: March 2024

INTRODUCTION: Esophagus cancer is the fifth most frequent tumor in the gastrointestinal tract, responsible for 358 thousand deaths per year (1). Because most of the
patients are asymptomatics, clinical suspicion is usually low. As it is a rapidly progressive cancer, it needs a fast intervention. This is guaranteed by the law n° 127232/2012,
in which an oncologic patient must start treatment at least 60 days after diagnosis.
This research aims to analyze if this right was guaranteed in Brazil between 2018
and 2021, considering the COVID-19 pandemic period. OBJECTIVES: To establish a
comparison in the time between the diagnosis and the treatment of esophagus cancer
in Brazil, during the biennia 2018-2019 and 2020-2021, considering the impact
of COVID-19 pandemic. METHODS: This research is an ecologic study with secondary
data, about the consequences of the pandemic in the time to start the treatment of
malignant esophagus neoplasm in Brazil, between 2020-2021 and 2018 and 2019.
The data was obtained from the “PAINEL – oncologia do Departamento de Informática
do Sistema Único de Saúde (DATASUS)”, considering the variables' time to start the
treatment and year of treatment. The data was analyzed and categorized utilizing the
program Microsoft Excel (2019). RESULTS: Between 2018 and 2021 there were 19186
patients diagnosed and treated, the number of treated people in at least 60 days after
the diagnosis being 9713 (50,62%), while the ones in which the beginning in less than
60 days was 9473 (49,37%), a difference of 240 (2,5%). There was a non-linear increase
in the number of patients treated in more than 60 days, with a decay of 0,98% in 2020
and, right after, an increase of 2,18% in 2021. However, from 2019, the cases with more
than 60 days to treat stand out in relation to the less than 60 days. Still, it was observed
a discreet increase of 328 cases (6,46%) with less than 60 days to treat in the whole
period. CONCLUSION: This study showed that the treatment in more than 60 days
after the diagnosis of esophagus cancer has increased quantitatively in a non linear
form, while the treatment in less than 60 days increased discreetly in percentage value.
Considering these findings, it is suggested that treatment made in more than 60 days
has increased during the COVID-19 pandemic, evidencing a possible delay in the start
of the treatment in Brazil during this period.

Prostate cancer mortality temporal trend in Brazil
Authors: Gandarela Auana Almeida Cooppieters , Silva Sabrina Neres Guimarães
Published: March 2024

Prostate cancer (CaP) is the second most common malignant tumor among
men in Brazil and represents a significant factor in mortality when diagnosed
late. Studies on mortality are relevant sources for understanding the epidemiological profile and measuring the importance of PCa as a public health
problem. The objective was to describe the distribution and temporal trends
of the mortality rate in different age groups (30 to 80 years or more) in Brazil
between the years 2011 - 2020. The research has a quantitative and analytical
character, through the collection of mortality data in the Mortality Information System (SIM) of the Ministry of Health (SIM/MS/DATASUS). The mortality
rate due to malignant prostate neoplasia was calculated annually, considering age range, and then arranged in simple dispersion data. According to the
analyses, it was observed that the incidence of prostate cancer was 95.17%
in individuals over 60 years of age, highlighting the age group of 80 years or
more in which it was 44%. Furthermore, the mortality rate prevailed in white
ethnic groups, with low education and married people. Among the years analyzed, the period with the peak in mortality was in 2017, representing 29.25%.
Furthermore, a linear decline in PCa mortality rates was evidenced in all age
groups between 2011 and 2020. However, there was a higher prevalence of
deaths from the sixth decade of life onwards, with emphasis on the population over 80 years. And, it was possible to observe a lower number of deaths
among individuals aged 30 to 59 years.
FILOSOFIA DA PÓS-MODERNIDADE
Authors: Ussivane Inocélio
Published: March 2024

O debate filosófico, que provocou o surgimento do debate que fazemos neste livro, é a suposta crise da modernidade e dos seus fundamentos, neste caso, a sua avidez de criar o monoculturalismo metodológico, e, consequentemente, cognitivo. A modernidade pretendia criar uma ciência e um pensamento filosófico sólido, universal e completo, com uso dos métodos positivos o que, de certa forma, se viu como tarefa difícil de realizar, daí que vários pensadores, como Lyotard, levantam um conjunto de reflexões sobre os obstáculos e impossibilidades de se perceber, conhecer e explicar o mundo através da razão instrumental e especulativa, o que permite levantar a importância do resgate de outros tipos de narrativas.
Com este trabalho, pretende-se dar uma contribuição ao problema da crise da racionalização da realidade moderna, que vai dar espaço a pequenos saberes, isto é, resgate dos fenómenos e eventos que estão para além do alcance científico e da compreensão racional nos cânones epistemológicos e regras metodológicas positivistas. Com a modernidade, o ser humano passa a trabalhar com ideias verificáveis e falíveis em torno da verdade (provisória), como diz Feyerabend. Isto significa que a inclusão de novas teorias, no contexto do pensamento de Popper, Kuhn e Morin, as quais, quando estiverem relacionadas, promovem mudanças. O pensamento científico passa a dar espaço ao discurso pós-moderno sobre a ciência.

Published: March 2024

Abstract. Head space volatiles from flowers, as well as green and ripe mango fruit of cv. Ataulfo from Soconusco, Chiapas, were collected using Solid Phase Microextraction (SPME). Identification of chemical species was carried out by Gas Chromatography-Mass Spectrometry (GC-MS). A complex mixture of monoterpenes and sesquiterpenes was found. 3-carene, α-pinene, myrcene, limonene, terpinolene, β-selinene and the sesquiterpene tentatively identified as germacrene D were the major constituents. This information could be valuable to characterize certain aspects of genetic traits, which in turn will be useful for breeding programs, and to provide assessment of cross pollination techniques.
 
Resumen. Los compuestos volátiles emitidos por flores y frutas verdes y maduras de mangos de la variedad Ataulfo del Soconusco, Chiapas fueron colectados por medio de la técnica de Microextracción en Fase Sólida (MEFS). El análisis químico de los volátiles se llevó a cabo por Cromatografía de Gases y Espectrometría de Masas (CG-EM). El análisis mostró que los volátiles del mango están formados por una mezcla principalmente de monoterpenos y sesquiterpenos. 3-careno, α-pineno, mirceno, limoneno, terpinoleno, β-selineno y el sesquiterpeno tentativamente identificado como germacreno D fueron los principales constituyentes. Esta información será de mucha utilidad en los programas de mejoramiento genético de variedades de mango, ofreciendo así confirmación del éxito de las técnicas de polinización cruzada.

Authors: Jori Nadir , Islas María Soledad , Ferrer Evelina Gloria , Williams Patricia Ana María
Published: March 2024

Abstract. Aliskiren (Alk) is a highly selective competitive inhibitor of renin used for the treatment of hypertension and related cardiovascular diseases. With the aim of improving its biological properties by the strategy of the induction of favorable conformational changes, we designed a metal-based drug. In this work we report the synthesis of a solid copper(II) complex with aliskiren, CuAlk, and its characterization in solution and solid-state. Moreover, and based on the association of hypertension with elevated levels of reactive oxygen species (ROS), the antioxidant properties of CuAlk were studied measuring the activities against 2,2-diphenyl-1-picrilhidrazil (DPPH·), hydroxyl (OH·) and peroxyl (ROO·) radicals, in addition to its superoxide dismutase (SOD) simil activity. Both the ligand and the complex were able to scavenge hydroxyl radicals, but upon complexation, the SOD mimetic activity of the ligand is enhanced.
 
Resumen. El Aliskiren (Alk) es un inhibidor por competencia altamente selectivo de la renina que se utiliza en el tratamiento de la hipertensión y enfermedades cardiovasculares relacionadas. Se diseñó un metalofármaco con la idea de mejorar las propiedades biológicas mediante la inducción de cambios conformacionales favorables. En este trabajo se reporta la síntesis de un complejo sólido de cobre(II) con aliskiren, CuAlk, junto con su caracterización en fase sólida y en solución. Además, de acuerdo con la relación que existe entre la hipertensión y los niveles elevados de especies reactivas de oxígeno (ROS), se estudian las propiedades antioxidantes del CuAlk frente a los radicales 2,2-difenil-1-picrilhidracilo (DPPH·), hidroxilo (OH·) y peroxilo (ROO·), además de la actividad superóxido dismutasa símil (SOD). Tanto el ligando, como el complejo fueron capaces de secuestrar radicales hidroxilos, pero, luego de la complejación, se mejoró la actividad SOD símil del ligando.
Non-covalent Interactions in Dihalogenated Compounds Ch(C6H4CH2X)2 (Ch = O, S; X = Cl, Br, I). Synthesis, Crystal Structure, and Hirshfeld Surface Analysis

Abstract. In this work, the synthesis and structural study by means of single-crystal X-ray diffraction of compounds of general formula Ch(C6H4CH2X)2 (Ch = O, S; X = Cl, Br, I) is reported. These compounds contain two flexible hydrocarbonated arms –CH2–X in the ortho positions to the Ch heteroatom. These compounds were synthesized through a linear synthesis starting from diphenylether or diphenylsulfide. Based on the structural analysis, we describe the more relevant molecular features as well as the non-covalent interactions that the heavy halogen atoms display with other moieties that promote the cohesion of the crystal arrangement. The Hirshfeld analysis displayed that the X···π, X···X, and C–H···X interactions are quite significant in the crystal arrangement.
 
Resumen. En este trabajo, se describen la síntesis y el estudio estructural de difracción de rayos-X de monocristal de seis compuestos con fórmula general Ch(C6H4CH2X)2 (Ch = O, S; X = Cl, Br, I), que contienen dos brazos hidrocarbonados flexibles –CH2–X en las posiciones orto al heteroátomo Ch. Estos compuestos fueron sintetizados a través de una síntesis lineal, partiendo de difeniléter o difeniltioéter. A través del análisis estructural se describen las características moleculares más relevantes, así como las interacciones no-covalentes que presentan los átomos de halógeno pesados con otros grupos funcionales para dar cohesión a la red cristalina. El estudio de las superficies de Hirshfeld mostró que las interacciones X···π, X···X y C–H···X son muy relevantes en esta cohesión.

Published: March 2024

Trigeneration plants (TGP) desired for combined production of electricity, heat and refrigeration are highly flexible to follow current loading. But their highest efficiency might be possible only when heat production coincides with its consumption, which is generally impossible in traditional TGP with applying the absorption lithium-bromide chiller (ACh) converting the heat, released from combustion engine in the form of hot water, into refrigeration. Usually, the excessive heat of hot water, not consumed by ACh, is removed to the atmosphere through emergency radiator. However, the well-known methods of TGP efficiency assessment do not consider those heat losses and give the overestimated magnitudes of efficiency for conventional TGP with ACh. The application of booster ejector chiller (ECh), as an example, for utilization of the residual waste heat, remained from ACh and evaluated about 25%, has been proposed to produce supplementary refrigeration for cooling cyclic air of driving combustion engine to increase its electrical efficiency by 3-4 %. In the case of using the supplementary refrigeration for technological or other needs the heat efficiency of TGP will increase to about 0.43 against 0.37 for typical TGP with ACh as example. The new modified criteria to assess a real efficiency of conventional TGP, based on ACh, are proposed which enable to reveal the way of its improvement through minimizing the heat waste. Such combined two-stage waste heat recovery system of TGP can be considered as the alternative to the use of back-up gas boiler to pick up the waste heat potential for conversion by ACh to meet increased refrigeration needs.
Efficiency analysis of fixed and axis tracking options of photovoltaic systems to be installed in a marina
Authors: Şahin Haci Mehmet
Published: March 2024

Electricity consumption is an important cost in businesses operating in the service sector such as marinas. Although the use of solar power for electricity has become widespread in various fields in Türkiye, marinas have yet to fully utilize this technology. The aim of this study is to examine the feasibility of supplying the electricity needs of a marina with a photovoltaic (PV) system. For this purpose, a marina in Muğla (Bodrum) was selected, and monthly/yearly electricity needs were determined. In this study, the PV installed capacity needed to meet the marina's electricity demand was selected. Simulations were performed for three different options using the Photovoltaic Geographical Information System (PVGIS). According to the calculations, a 2012 kW single-axis tracking PV system generated 4,469,618 kWh/year of electricity, which is sufficient to meet the annual electricity demand. It has been determined that the installation cost payback period is 3.91 years for the single-axis tracking PV system. In addition, it was observed that both the dual-axis tracking and single-axis tracking PV systems were more efficient than the fixed options.

In this sense, it is a matter of research to provide the segment under study with adequate administrative, financial and control strategies; how to handle it and how they should be carried out in the face of the current situation, thus promoting empowerment in unprotected sectors and highlighting, above all, interculturality and diversity in the countries.
Lipid-based nanoparticles and their recent advances
Authors: Onteru Sujeevan
Published: March 2024

Lipid-based nanoparticles hold great potential for drug delivery, providing biocompatibility and the ability to encapsulate both hydrophilic and hydrophobic drugs. However, there are certain challenges associated with small molecules, such as leakage and premature release, which can compromise their effectiveness. Despite these challenges, lipid nanoparticles offer advantages in terms of solubility, stability, and targeted delivery, thereby reducing side effects. Additionally, they can be customized for specific molecules, ensuring biocompatibility and biodegradability. While complications may arise, lipid nanoparticles offer numerous benefits for loading biomolecules, improving pharmacokinetics, and enhancing therapeutic effects. It is important to address stability and loading challenges when encapsulating biomolecules and consider potential immunogenic responses that may impact biocompatibility and safety.

Published: March 2024

In Nigeria, there are many different security concerns and thus crimes have increased despite the fact that there are stringent laws and punishments in place to deter them, making it appear as though the authorities are unable to stop it. In order to identify criminals and conduct investigations, it is imperative that a facial recognition system be connected to a constantly updated digital library. The focus of this paper is to develop an automatic criminal investigation system that can identify criminals based on their faces and produce real-time digital archives about them. However, as an object detection method and facial recognition model, the new system is built on the Haar Cascades Classifier technique in the OpenCV package. Additionally, appropriate programming languages that may provide the needed results were investigated. Python 3.6 was used with the Django 4.2 framework, OpenCV-Python, and Dlib for language execution. Due to Django's ORM, support for numerous databases, and usage of the SQLite3 database, a straightforward database was employed for lightweight applications. The 12 factor app idea was used to construct the DICA-FR system's essential skills. Face detection was applied to the image using the Haar method during processing, and during post-processing, the discovered face was compared with well-known criminal face encodings for matching purposes. Results demonstrated that DICA-FRS could effectively replace human systems since it can recover faces from the furthest distances, display the name of the offender, and sound an alert on the DICA web app's output screen. The DICA system is a working prototype of a system that might be used in the criminal investigative process in Nigeria.

Authors: AKÇAKIN Veysel , CEBESOY Ümran Betül
Published: March 2024

This study explored the effects of STEM-based instruction on the mathematics teaching self-efficacy of preservice mathematics teachers and their opinions about STEM-based instruction. A total of 23 senior preservice mathematics teachers participated in the current study. The concurrent mixed method design, which is characterized as collecting two types of data (qualitative and quantitative) at the same time, was utilized. Data were collected through Mathematics Teaching Efficacy Belief Instrument (MTEBI) and open-ended questionnaire developed by the authors. Results suggested that mathematics teaching self-efficacy scores of preservice mathematics teachers differed significantly in favour of post-instruction. The number of participants who felt competent to integrate STEM disciplines increased after the instruction. Moreover, STEM-based instruction improved preservice mathematics teachers’ personal beliefs concerning mathematics teaching efficacy and mathematics teaching outcome expectancy. Another important finding was that the preservice mathematics teachers’ awareness about the connection between mathematics and other disciplines was improved and they felt more capable of integrating STEM disciplines after STEM-based instruction.

Authors: Padrón Brito Laura
Published: March 2024

Las prácticas son una parte esencial de la integración de los futuros docentes en el mundo de la educación. Este estudio examina las repercusiones y los beneficios de la presencia de estudiantes del Máster de Formación del Profesorado en las aulas de Educación Secundaria, tanto desde la perspectiva de los profesores como de los alumnos de esta etapa. Se recopilaron datos cualitativos y cuantitativos mediante cuestionarios y entrevistas con 153 estudiantes y 16 profesores de varios centros de Educación Secundaria de las Islas Canarias. Los resultados revelan que tanto profesores como alumnos reconocen beneficios pedagógicos, pero señalan la falta de conexión emocional entre los futuros docentes y los estudiantes. Además, se subraya que los cambios legislativos pueden obstaculizar las funciones de tutoría. Se destaca la necesidad de directrices homogéneas, para garantizar el logro de objetivos durante las prácticas y optimizar la interacción entre los futuros docentes y la comunidad educativa.

Authors: Dadparvar Shabnam , Kaleji Vali , Ghoreishi Seyedeh Zahra , Mianabadi Hojjat
Published: March 2024

The Aras River Basin, a significant transboundary river basin in the Caucasus region, is shared among four riparian countries, including Türkiye, Armenia, Iran, and Azerbaijan. Although positive measures have been taken to enhance water cooperation in this river basin, the Eastern Anatolia Project (DAP) and the hydraulic mission of Türkiye remain the primary factors that could potentially reverse the cooperative atmosphere of the basin and lead to conflict. In recent decades, Türkiye has utilised transboundary water resources to bolster its economic power, advance political strategies, and establish hydro-hegemony. Despite the significant Mega-Project and hydraulic mission of the upstream in the Aras River Basin, they have not received adequate attention in hydro politics studies. This study employs secondary sources to investigate Türkiye’s actions in the region. It discusses the implications of Türkiye’s projects on downstream riparian states in general and Iran’s water resources, including dam construction.
ScholarOne - Team Interventions for Hybrid Teams: ‘Let’s Collaborate ASAP!’
Authors: Collins Catherine , Humphreys Kerry , Lusher Dean , Xia Mengting (Rachel) , Li Keyao , Griffin Mark
Published: March 2024

Our paper analyses commonly utilized team interventions and highlights
where these remain applicable for hybrid teams. Drawing on
interdependence theory, we argue that current team interventions tend to
build high levels of task interdependence, encouraging ‘let’s
collaborate ASAP’, which may contribute to an ‘always on’ culture. We
then recommend novel interventions for hybrid teams focusing on goal and
knowledge interdependence and embracing work uncertainties in Industry
4.0. These interventions come from Automation / artificial intelligence,
Sociology, and Accounting, complementing those from organizational
Psychology. We conclude that teams should still ‘collaborate ASAP’, but
with interdisciplinary interventions rather than ‘always on’ urgency.

Published: March 2024

This research aimed to investigate the sensitivity to the drug (ivermectin) in Kangal and Akbaş breed dogs, which are dog breeds native to Turkey, via the MDR1 gene mutation.
For the research, blood, hair and intraoral swap samples were taken from 30 Kangal and 20 Akbaş breed dogs (male-female mixed, adult) with ethical permission and approval forms. Kangal dog samples were taken from the dogs bred in the farms in Sivas center and Kangal village, and Akbaş dog samples were taken from the dogs bred in the farms in the Sivrihisar center, Ankara and Eskişehir regions. The samples taken were evaluated based on polymerase chain reaction (PCR) from the wool and subsequent two-way dideoxy chain termination reaction in the presence of 4 base farm deletions (c.296-299delAGAT) in the 4th exon of the ABCB1 gene that encodes the P-glycoprotein (P-gp) drug transporter protein.
According to the obtained DNA sequence results, the deletion of “AGAT” was not determined in any of the individuals screened. The results of this study, which is preliminary research, showed that Kangal and Akbaş breed dogs are safe in terms of sensitivity to drugs that are set to be absorbed and excreted by the P-gp pump, especially ivermectin. However, it would be useful to repeat the analysis of both breeds with more examples.
JUSTIFICATION OF THE BASIC PARAMETERS OF A DAIRY FARM FOR 500 COWS WITH ROBOTIC MILKING SYSTEMS
Authors: Lutsenko M. M. , Popkov V. V.
Published: March 2024

The article highlights the results of research on the assessment of the conditions for keeping high-yielding cows in a new type of room with a width of 36 m and a height of 10.5 m according to indicators of the microclimate and daily behavior of cows. It has been established that the volume-planning and technological solutions of this room with robotic milking systems provide comfortable conditions for keeping highly productive cows. So, the air temperature and relative humidity of the room meet the existing standards. The presence of side curtains and a light-aeration comb ensure a high speed of air movement at the level of 0.65 m/s, which has a positive effect on its gassiness. The ammonia content is at the level of 2.9 mg/m3 against 20 mg/m3 according to regulations, and the level of hydrogen sulfide is 0.2 mg/m3 against 10.0 mg/m3, and the level of carbon dioxide is two times lower.

Studying the behavior of cows under the conditions of a new type of room, it has been established that animals show the greatest activity during the change in daylight hours, and the least one - in the middle of the day or night. The behavior of cows under the conditions of the new technology changes depends on the productivity of the cows. Thus, as productivity increases, the duration of feed and water consumption and stay in the robotic box increases. Animals with the productivity of 20 kg stand for 13 hours and lie down for 11 hours, while cows with the productivity of 40 kg stand for only 10 hours and lie for 14 hours, which corresponds to their physiological needs.

Based on the obtained research results, we have justified the main parameters of a new type of premises with robotic milking systems for 500 cows.

Este artículo analiza la producción del espacio turístico en la comunidad Río Arcotete del municipio de San Cristóbal de Las Casas, Chiapas. Se muestra el proceso mediante el cual los gobiernos federal y estatal de Chiapas han creado las condiciones para que una comunidad indígena que adolece de una crisis agrícola y con una pluriactividad acentuada se involucre en los servicios turísticos. Los resultados muestran que bajo las condiciones que impone el mercado turístico, los indígenas se han apropiado de esta actividad productiva, lo cual ha generado una dinámica de cambios intracomunitarios que fortalecen sus ingresos, pero a condición de una dependencia cada vez mayor del turismo. El reto que ahora tiene la población originaria es cumplir con las circunstancias que el mercado implanta, lo cual la debilita y genera una lenta maduración del destino turístico. La investigación es cualitativa basada en fuentes primarias y trabajo de campo.
Korekta językowa polskiej adaptacji Kwestionariusza kodów moralnych (MFQ-PL)
Authors: Kelley Leslie J. , Fanslau Agnieszka , Kałowski Piotr
Published: March 2024

Niniejszy artykuł ma na celu korektę szeregu językowych nieścisłości pomiędzy polskojęzyczną i anglojęzyczną wersją 30-itemowego Kwestionariusza kodów moralnych (Moral Foundations Questionnaire, MFQ) i przedstawienie zrewidowanego polskiego tłumaczenia kwestionariusza, które będzie lepiej przystosowane do badań międzykulturowych. Badacze, którzy nie znają języka polskiego i anglojęzycznej wersji MFQ, mogą nie być świadomi różnic między tymi dwoma wersjami językowymi. Różnice te są z kolei istotne, ponieważ MFQ stosuje się do porównywania fundamentów moralnych pomiędzy różnymi kulturami. Precyzja tłumaczenia jest kluczowa w badaniach międzykulturowych, gdyż rozbieżności w znaczeniu mogą prowadzić do wyciągania błędnych wniosków na temat różnic międzykulturowych. W artykule prezentujemy zrewidowaną wersję polskiego tłumaczenia 30-itemowego MFQ. Uważamy, że trafniej oddaje formę i treść anglojęzycznych itemów. Nasze tłumaczenie potencjalnie przyczyni się do bardziej spójnych porównań fundamentów moralnych pomiędzy polskojęzycznymi i innymi próbami.
