On the radiative and multiple reflection corrections of the van der Waals force between two particles/atoms: dipolar contribution
Authors: Zurita-Sánchez Jorge R.
Published: July 2023

We present a theoretical formalism based on fluctuational electrodynamics and the Maxwell-stress tensor for describing the impact of radiative and multiple reflections corrections on the van der Waals force between two nanoscale spherical particles and a pair of atoms in the dipolar approximation. Particularly, we examine the van der Waals forces for two metallic particles whose dielectric constant is represented by the Drude model, for two dielectric particles in which their material response has phononic resonances, and for two atoms with dynamic polarizabilities containing a single resonant frequency. For the metallic particles, in relation to the case in which the aforementioned effects are omitted, the van der Waals force is unchanged by the radiative corrections of the polarizabilities, whereas the mechanism of multiple reflections perturbs force about a few percentage points when the spheres nearly touch each other. In contrast to the the metallic case, the radiative corrections of the polarizabilities of the dielectric particles modify peculiarly the van der Waals force in comparison to the case where such corrections are neglected; there is a critical interparticle separation that divides two regimes: when the interparticle separation is smaller (larger) than this critical distance the force with radiative corrections is smaller (greater) than that without these corrections. Moreover, the van der Waals force is practically unchanged when effect of multiple reflections is taken into account. For the atomic case, the deviation of the van der Waals force due to multiple reflections is about a few percentage points when the interatomic separation corresponds to twice the van der Waals radius, and this deviation can reach about seventeen percent at a separation of 2.5 times the atomic radius. This work might have implications concerning the fine-tuning between theoretical and experimental outcomes of the van der Waals forces.
Studying quarkonium in the anisotropic hot-dense quark-gluon plasma medium in the framework of generalized fractional derivative
Authors: Abu-Shady M.
Published: July 2023

By applying the generalized fractional-Nikiforov-Uvarov (GF-NU) approach, the radial Schrodinger equation is analytically solved. The energy eigenvalues and associated functions are calculated by extending the interaction potential to an anisotropic hot-dense QCD medium. For heavy quarkonium masses like charmonium and bottomonium, the special cases of the mass of quarkonium are obtained at α=β=1. The effect of the fraction parameter is investigated within the context of the QCD medium on binding energy and dissociation temperature when baryonic chemical potential is included. Recent works are compared and studied. Therefore, the fractional quark model correctly represents heavy mesons in an anisotropic hot-dense QCD medium, according to the current findings.

TOXICIDAD DEL LODO DE PERFORACIÓN MINERA EN EL BIOINDICADOR PORCELLIO LAEVIS (LATREILLE, 1804) (CRUSTACEA: ISOPODA)
Authors: Bautista-Medina Yadira Blanca , Iannacone José
Published: July 2023

Se evaluó la toxicidad del lodo de perforación minera en base al efecto letal y de evasión en el bioindicador terrestre Porcellio laevis (Latreille, 1804). Se consideraron los siguientes tratamientos: lodo de perforación, fase suspendida del lodo de perforación y fluido de perforación minera en ensayos de toxicidad aguda y prueba de evasión de corta duración. Los ensayos de toxicidad no mostraron un efecto letal en el lodo de perforación, en la fase suspendida del lodo de perforación y en el fluido de perforación minera en P. laevis. En las pruebas de evasión, considerando condiciones de humedad no controladas se observó que hubo preferencia de P. laevis hacia la tierra con presencia del lodo de perforación. Sin embargo, considerando condiciones de humedad controladas se confirmó la preferencia de los P. laevis hacia la tierra con lodo. Los resultados de la presente investigación permiten documentar un protocolo para evaluar la toxicidad de los lodos de perforación minera y sirven como referente para futuras investigaciones en el Perú.

La situación se presenta también en el contexto de la Universidad de Ciencias Médicas de Villa Clara, Cuba, cuyos profesionales, por supuesto, forman parte de la sociedad. De ahí, el objetivo del artículo: Analizar algunos fenómenos nocivos y recurrentes en el lenguaje actual de profesionales universitarios. Se emplearon en la investigación, esencialmente, los métodos teóricos análisissíntesis, e inducción-deducción; además, los métodos empíricos de observación y revisión documental. Paralelamente, ha resultado provechoso el intercambio sistemático con los profesionales de la Institución. Entre los fenómenos más significativos detectados se encuentran: el desdoblamiento indiscriminado del sustantivo en los géneros masculino y femenino ―bienvenidas y bienvenidos…―, la tendencia a la verbalización de sustantivos y adjetivos ―aperturar (apertura); negativizar (negativo)…―; la inadecuada fragmentación sintáctica de perífrasis verbales de infinitivo ―decir que…, resaltar que…―. Estos hechos contribuyen, en los dos primeros casos, al incremento de la verbosidad estereotipada y, en el tercero, a la ruptura lógica de la expresión al suprimirse el verbo auxiliar y emplear solamente el infinitivo ―algo similar al lenguaje aborigen―. En fin, los fenómenos analizados son muy nocivos en la comunicación social; pero, más aun, en el habla de los profesionales universitarios, quienes inconscientemente deterioran su expresión paulatinamente. Ello entra en clara contradicción con las normas y características del lenguaje y estilo científicos, al cual deben ceñirse en su proyección lingüística profesional.

La valoración sobre el manuscrito científico resulta un proceso complejo, pues depende del tipo de propuesta y la cultura metodológica que posea el evaluador para comprender las instrucciones de revisión. El objetivo del estudio fue comparar las diferencias y semejanzas metodológicas en el sistema evaluativo de tres revistas latinoamericanas indexadas. Se seleccionaron las revistas: Acta Biológica Colombiana: -ABC (Colombia), Revista Internacional de Contaminación Ambiental: -RICA (México) y The Biologist: -TB (Perú). Fueron contabilizados los aspectos de evaluación para los autores siendo un total de 11 (ABC), 6 (RICA) y 11 (TB). Las principales diferencias radicaron en criterios de orden metodológico debido a, informaciones generales relacionadas con el tema investigación y específicas de desarrollo estructurales, señalamiento sobre el lenguaje científico, además, de sugerencias o no, a los autores. Se observaron dos semejanzas cardinales que destacaron en la cualificación sobre la interrogante a medirse y falta de indicación directa por parte del evaluador hacia los autores. Aunque las revistas presentaron formatos de evaluación, cumplir con sus requisitos solo resulta de la formación metodológica y técnica por parte del experto–evaluador. Se concluyó que, no existió una estandarización en los criterios metodológicos del sistema de evaluación sobre los manuscritos en las tres revistas indexadas latinoamericanas.

Authors: Mutlu Öztürk Hande , Öztürk Harun Kemal
Published: July 2023

The main idea of this study is to investigate Türkiye’s meat consumption, projection and supplies by using the structure of the Turkish meat industry and Turkish economic indicators. This present study develops several models for the analysis of meat consumption and makes future estimations based on the Regression Analysis Meat Consumption Model (RAMCM). Four forms of Regression Analysis models are used to estimate meat consumption. These models are named Multiple Linear Regression Analysis (MULIRA), Linear Regression Analysis (LIRA), Polynomial Linear Regression Analysis (POLIRA), and Logarithmic Linear Regression Analysis. The models developed in the linear and non-linear forms are applied to estimate meat consumption in Türkiye based on social and economic indicators; Population, Gross National Product (GNP) per capita, Imports of goods and services (% of GDP), Exports of goods and services (% of GDP), electricity consumption per capita, unemployment, Gross capital formation (% of GDP) figures. It may be concluded that the Multiple Linear Regression Analysis models can be used as alternative solutions and estimation techniques for any country's future meat consumption values.
The influence of different pressure magnitudes and solvents on the functional properties and color stabi-lity of blackberry (Rubus plicatus L.) extracts
Authors: Başkaya Sezer Duygu
Published: July 2023

Phenolics have a protective effect against many diseases, such as cancer, cardiovascular diseases, hypertension and diabetes, owing to the antioxidant capacity they form. Blackberries are known as a functional food due to their high phenolic content. In this study, the extracts were obtained from untreated and hydrostatic pressure (300 MPa or 600 MPa) treated blackberry puree using water, ethanol, methanol and acetic acid (1%) or hydrochloric acid (1%) added forms of these solvents. Then the phenolic content, antioxidant capacity and color values were determined on the 0th and 7th days. The highest phenolic content and antioxidant capacity were obtained with alcohol extraction with added hydrochloric acid, and the lowest values were obtained with water extraction. It was determined that hydrochloric acid extracted more phenolic substances than acetic acid and increased the antioxidant capacity. It was found that L* values were lower, a* and b* values were higher in samples with high phenolic content. Compared with the untreated samples, it was determined that the pressure increased the phenolic content and antioxidant capacity (p<0.05). The effect of 600 MPa was found to be more pronounced in the presence of acid-added solvents. A correlation was detected between the phenolic contents, antioxidant capacities, and color values. As a result, extraction in hydrochloric acid-added ethanol medium is recommended to increase the functional properties of blackberry fruit.

This study aims to examine the perceptions of young people between the ages of 18-22 in Türkiye, studying at universities and representing Generation Z regarding the consumption of animal-free milk and to determine whether there will be a consumer base for animal-free milk in Türkiye in the coming years. For this purpose, 620 students were informed to participate in the research, but data were collected from 215 individuals. A face-to-face interview was conducted with the individual. 32.55% of the participants stated that they could consume animal-free milk. 27 (30%) of 90 female participants and 42 (33.6%) of 125 male participants stated that they could consume animal-free milk. Participants stated that they would not consume animal-free milk because they were concerned that animal-free milk is unhealthy, unnatural, insufficient in terms of nutritional value, unsafe, negatively affecting animal husbandry, and posing a problem in terms of belief. As a result, it has been seen that the Z-generation individuals living in Türkiye have the potential to consume animal-free milk. Suppose the participants’ concerns are clarified, and their familiarity with this product is increased. In that case, it is predicted that there will be a more severe increase in the animal-free milk consumption potential future in Türkiye.

Economic expansion is a positive side effect of national highway construction initiatives. So, the plan is to construct these projects rapidly. This calls for premium asphalt. As a result of aggregate gradation variation, numerous asphalt mixes have been rejected and rebuilt on-site in recent decades, resulting in the waste of valuable resources and valuable time. Consequently, the goal of this study was to examine the durability of asphalt mixes where the aggregate gradation ranged from +4% above to 2% below the standard range. The aggregate gradation is inconsistent throughout HMA manufacture. The aggregate is graded at 2, 4, and 6 percent over and below the allowed range. Case in point: the gradation of the control mix design. Marshall There was a quantitative evaluation of mixed properties throughout the design phase. HMA mix performance was evaluated via high temperature and water cycles by vehicle pressure observation and Indirect Tensile Strength (ITS) testing. In hot climates, asphalt with gradations above +4% and 2% of both the higher and lower standard values showed the greatest resilience to water damage and the least rutting. In warm regions, asphalt mixture design will be constrained by the higher aggregate gradation limits.

Maintaining and increasing the volume of underground coal mining is possible only if there is a highly efficient technology for conducting and maintaining preparatory workings. The purpose of the research was to assess the parameters of stability control of the contours of the mine workings, anchored with anchorage, to create a technology for intensive and safe excavation of mine workings based on the identified patterns of behavior of adjacent rock massifs. The idea of the approach is to use a man-made stress-strain state to develop an effective technology for fixing a contour rock mass. The mechanism of deformation, displacement, and collapse of rocks in a structurally disturbed inhomogeneous mountain range is investigated to assess the state of the rock mass around the mine workings. The technology of fastening contiguous soil rocks has been developed taking into account the state of the mountain massif around the workings and the parameters of the operation of the anchor supports in mines for fixing rods in workings in order to ensure the safety of mining operations in the mines of the Karaganda coal basin have been determined.

The paper presents the outcome of a comprehensive study at macro- to nanoscale levels of enrichment products from technogenic wastes. The products were obtained thanks to the experience of gravity enrichment during the treatment and preparation of the gold and REE sample material with preliminary mechanical and thermal activation. Thermal activation was applied for the first time. Native gold was identified in the form of single, micron-sized grains and, according to technological testing of enrichment products, there is a predominance of "invisible" dispersed gold. The gold content in the initial material was 2.93 g/t, which upon thermal activation of the sample increased to 6.37 g/t. According to the spectral analysis and electron probe microanalysis, the products of all enrichment stages are characterized by an increased content of yttrium and REEs. The REEs occurrence forms were determined. REEs are mainly found in micro- and nano-sized fluorine and fluorine-free phosphates (in apatite, by substitution of calcium), in REE-phosphates (in xenotime), and less often, possibly, in complex sulfo-phosphates and phosphate silicates. In thermal products consisting of inhomogeneous aggregates of nanosized phases, according to X-ray phase analysis, considering the elemental composition, REEs are included in the composition of phosphates: florensite and phases Ce(P5O14), Ca8MgSm(PO4)7.

Currently, uranium production occupies a decisive place in the world energy industry. In Kazakhstan, to meet the demand for uranium, hydrogenous deposits with technologically and economically favorable natural indicators are being developed, including the large Semizbai deposit. The deposit by genesis belongs to the hydrothermal-hydrogenous polygenic type in terrigenous sandy-clayey deposits. As a result of geological studies, the stratification of the ore-bearing deposits of the Semizbai suite was established: the lower and upper ore-bearing sub suites, the geometrization of the deposit was performed, and the morphology, number, and size of ore bodies were identified. Most of the balance reserves of the Semizbai deposit are concentrated in large and medium ore bodies. Analytical work and description of thin sections and polished sections under a microscope determined the material composition, textures, and structures of uranium ores, the main ore minerals, and their distribution in ores. When carrying out field and laboratory work, geological indicators of the deposit were obtained to select the technology for extracting ores. To select and justify the field development technology, special technological studies were carried out in the experimental area. Based on the geological indicators of uranium ores for the Semizbay deposit, well-in-situ leaching was chosen as the most rational for hydrogenous deposits. The characteristic of associated useful components of uranium ores is given, and the increased content of selenium, germanium, and scandium in them is established. The obtained research results can serve as a basis for improving the technology used for mining uranium ores and extracting associated components from them.

In this research, we aim to examine the direct and indirect effects of leader-member exchange on employees’ job satisfaction through the mediating roles of perceived organizational support and work engagement. Consequently, this study aims to close this gap in the extant literature. Structural equation modelling method was chosen because it is a very useful method to analyse highly complex multiple variable models and to reveal direct and indirect relationships between variables. Quantitative data was collected in a five-point Likert scale. Confirmatory factor analyses have been conducted to determine the convergent validity. Composite reliability and AVE values have been used to determine reliability and discriminant validity of the scales respectively. The hypotheses have been tested by means of structural equation modelling method. As a result of the analyses performed in this study, it has been empirically proven that leader-member exchange has a positive impact on job satisfaction. Furthermore, both perceived organizational support and work engagement mediate the relationship between leader-member exchange and job satisfaction. These results are in accordance with the extant literature. This study attempts clarify the mechanism behind the relationship between Leader-Member Exchange and Job Satisfaction by examining the role of perceived organizational support and work engagement concurrently.

Bu çalışmanın amacı, Türk lirasının, uygulanan ekonomi politikaları ışığında, diğer döviz para birimlerine göre baskı altında kalıp kalmadığını analiz etmektir. Bu analizin temelinde, ABD dolarının Türk lirasına karşı, 2001 Bankacılık Krizinden itibaren zaman içerisinde değer yükselişi olup, gözlemlenebilir veriler ışığında, yerel piyasada Döviz Piyasası Baskısı (DPB) endeksi hesaplanmaktadır. Weymark (1997) dışa açık ekonomi modeli temeline oturtulan çalışmada, değişkenlerin beklenti değerlerini bulmak için otoregresif model kullanılıp, İki Aşamalı En Küçük Kareler (2SLS) sonuçlarına ulaşılmaktadır. Modelde kullanılan değişkenlerin ilgili parametrelerini tahmin etmek için gözlemlenen verilerin zaman aralığı, 1998 yılının birinci çeyreğinden 2020 yılının ikinci çeyreğine kadar olan dilimi kapsamaktadır. Sonuçlara göre, 2001 yerel ekonomik kriz sırasında DPB endeksi yüksek değerler verip, Türk lirası değer kaybı yaşarken, kriz sonrasında uygulanan ekonomi politikaları sonrası endeks değerleri düşüş göstermiştir. 2018 senesi üçüncü çeyreğine kadar devam eden bu süreç, aynı dönemde yaşanan döviz kuru krizi ile DPB endeksinde tekrar yükselişe geçildiğini gözlemlenmektedir. Sonuçlar, ekonomi uzmanlarından, küresel yatırımcılara kadar olan geniş bir kitleye hitap etmektedir.

The main purpose of this study is to investigate the relationship between employment intensity and growth in Turkey’s manufacturing and service sectors via taking into consideration the Eurostat technology classification for the period between 2003 and 2015. Relying on a - Constant Elasticity of Substitution (CES) production function, employment demand functions are estimated for different manufacturing sub sectors with different technology levels and service sectors with different information content. The results reveal that real wages are the main determinant of employment demand with a negative coefficient, in line with the related literature. Employment elasticities of output have been positive and statistically significant, except for the medium-low (ML) technology sub sectors. Manufacturing sub sectors has relatively low and insignificant coefficients which could be considered as a weak sign of jobless growth. The interest rate seems to be negative and statistically significant. On the other hand, we did not find any significant relationship between inflation (inf) and employment demand except for less knowledge-based service (LKIS) sectors.

Yaşanan küresel değişimler tüketicilerde tüketim alışkanlıklarına dair farkındalık meydana getirmiş, tüketicilerin çevreyi koruyan en azından kirletmeme özelliği bulunan ürün ve hizmetleri talep etmeye başlaması da şirketleri harekete geçirmiştir. İşletmeler bu doğrultuda üretim, kullanım ve bertaraf etme sürecinde çevreci ürün ve hizmetlere yönelmeye başlamışlardır. Böylece ‘yeşil’ sıfatını alan ürünler, tüketiciler, reklamlar vb. birçok kavram ortaya çıkmıştır. Yeşil pazarlamayı faaliyetlerinin odak noktası haline getiren şirketlerin fazlalaşması ile beraber bu durumu suistimal eden işletmeler de ortaya çıkmıştır. Çevre sorunları konusunda yeterli hassasiyete sahip olmayan işletmeler bile kendilerine fayda sağlama amaçlı olarak ‘yeşil’ bir üretim ve pazarlama anlayışına yönelmişlerdir. Bu durum neticesinde dilimize ‘yeşile boyama’ ‘yeşil yıkama’ olarak çevrilen ‘greenwashing’ kavramı literatüre dahil olmuştur. Bu araştırmanın konusunu ‘yeşil göz boyama’ oluşturmaktadır. Araştırmanın amacı ise ‘yeşil göz boyama” kavramını literatür taraması yöntemiyle geniş bir perspektiften incelemek olarak belirlenmiştir. Dileğimiz, Ülkemizde kurumların daha fazla duyarlılıkla üretim yapmaları, doğanın, toplumun ve kurumların devamlılığının birlikte sağlanabileceğini unutmayarak; doğrulara ve samimiyete odaklanıp çevre konusunda bilinçli, yeşil tüketicilerin oluşturulmasında kapsamlı iletişim çalışmalarını gündemlerine almaları olacaktır.

Published: July 2023

Örgütsel destek, işgörenlerin refahına yönelik tedbirler alınması ve çeşitli uygulamalar geliştirilerek sağlıklı, verimli ve karşılıklı iyi ilişkiler üzerine kurulu bir ortamının tesis edilebilmesidir. Örgütler her ne kadar bu yönde çabalar sarf etse de algılanan durumun ötesine geçmek oldukça güçtür. Bu nedenle örgütsel desteğin yansımasının belirlenmesinde bir ölçüt ve işgörenlerin örgütleri tarafından kendilerine verilen değere ilişkin duygusal bir algılama olan Algılanan Örgütsel Destek (AÖD) kavramı devreye girmektedir. Çalışma ortamında olumlu duyguların ortaya çıkarılabilmesi ve sürdürülebilmesinde AÖD’ye aracılık eden ve tamamlayıcısı durumunda kavram ise duygusal emektir. Duygusal emek, örgütün ihtiyaç duyduğu ve işgörenlerinden beklediği duruma uygun duygusal davranışların gösterilmesi olup yüzeysel, derin ve samimi davranış olmak üzere üç alt boyuttan oluşmaktadır. Örgütsel açıdan AÖD’nin işgören açısından istenen sonuçlar verebilmesi için duygusal emek sürecinin kontrol edilmesi ve yönetilmesi gerekmektedir. Bunun için de AÖD ile duygusal emek ve duygusal emek alt boyutları arasındaki ilişkilere bakılmalıdır. Bu araştırmada duygusal emeğin oldukça önemli ve değerli olduğu sivil havacılık sektöründe görev yapan kabin memurlarının örgütsel destek algıları ile duygusal emek davranışları arasındaki ilişkinin incelenmesi amaçlanmıştır. Araştırma 465 kabin memurunu katılımıyla tarama modeline göre gerçekleştirilmiştir. Araştırma sonucunda kabin memurlarının algıladıkları örgütsel destek algısı ile duygusal emek davranışlarından yüzeysel rol yapma arasında ters yönlü zayıf düzeyde, derinden rol yapma ile aynı yönlü zayıf düzeyde ve doğal duygular ile arasında aynı yönlü orta düzeyde anlamlı bir ilişki bulunduğu tespit edilmiştir.

Reperfusion of the ischemic brain parenchyma with intravenous thrombolysis and/or mechanical thrombectomy is the cornerstone of acute ischemic stroke treatment. A paradigm shift from “time is brain” to a more precision medicine approach now called “imaging is brain”, has taken place during the last decade. This transformation has been fueled by the progress in neuroimaging. Advanced Neuroimaging incorporates perfusion imaging in order to depict real-time cerebral perfusion disturbances and provide maps of the penumbra and ischemic core that will inform individualized clinical decisions. Advance neuroimaging has now a fundamental role in triaging patients that will receive reperfusion treatments beyond the conventional time windows of 4.5 hours for intravenous thrombolysis and 6 hours for mechanical thrombectomy. We provide a narrative review of all the pivotal observational studies and randomized-controlled clinical trials that supported the use of advance neuroimaging, as well as technical issues and pitfalls that may be useful for its implementation in routine clinical practice.
