The SEM fitted comprises the following links between traits: WBSF → LMA, WBSF → HCW, HCW → LMA, BF → HCW, and BF → MB, where the arrows indicate the causal direction between traits, with structural coefficients posterior means (posterior standard deviation) equal to −0.29 cm2/kg (0.09), 0.43 kg/kg (0.29), 0.10 cm2/kg (0.006), 1.92 kg/mm (0.28), and 0.03 score-grade/mm (0.006), respectively. The final SEM revealed some important putative causal relationships among the traits studied here. The implied causal effects suggest that interventions on meat tenderness and fat content would affect overall growth and muscle deposition. Knowledge regarding potential causal relationships inferred among the traits studied here can have important implications for the genetic selection and management of Nellore cattle for improvement of carcass and meat quality.

Balıkesir Üniversitesi, Fen Bilimleri Enstitüsü, Fizik Ana Bilim Dalı, Bu çalışmada kütlesi 50 Mʘ'den büyük olan ZAMS (Sıfır Yaş Ana Kol) model yıldızların içyapı sabitleri kj , ηj , ∆j'nin metallik ve kütleye göre değişimi incelenmiştir. Hesaplamalar, 50-100 Mʘ arasında kütleye sahip bir dizi yıldız modeli için yapılmıştır. Metallik değeri olarak, Z=0.0001 ve Z=0.03 aralığında olan değerler alınmıştır. Her model için katsayılar Clairaut-Radau'nun diferansiyel denklemi ile elde edilmiştir. Eggleton yıldız modelleri, EZ-Web derlemesinde kullanılmıştır. Sonuçlar, yüksek metal değerleri için ilginçtir. Evrimleşmiş yıldızlar için apsisli hareket sabiti k2'nin nasıl değiştiğini araştırılmıştır. Bu bağlamda eksantrik kütleli ikili sistemler olan HD 152218 ve HD 152248 için yıldız yaşına bağlı olarak k2 sabiti teorik olarak hesaplanmıştır. Sonuçlar en son teorik ve gözlemsel sonuçlarla karşılaştırılmıştır. Sonuçlar, büyük kütleli yıldızların içlerinin evrimleştikçe değiştiğini göstermektedir. Kütlesi 50 Mʘ'den büyük olan yıldız modelleri için içyapı katsayılarını hesaplamak için az sayıda çalışma bulunduğundan, bu sonuçlar çok büyük kütleli yıldızlar için gelecekteki teorik ve gözlemsel çalışmalara rehberlik edecektir., The variation of internal structure constants kj, ηj , ∆j of ZAMS ( Zero Age Main Sequence) model stars larger than 50 Mʘ mass according to metallicity and mass are investigated. Calculations are made for stellar model in the range of 50-100 Mʘ. Metallicities are taken between Z=0.0001 and Z=0.03. For each model, the coefficients are obtained by Clairaut Radau‟s differential equation. The Eggleton stellar models are used in EZ- Web compilation. The results are interesting for high metal values. We investigate how the apsidal motion constant k2 changes for evolved stars. In this context, we have computed the constant k2 theoretically depending on stellar age for the eccentric eclipsing massive binaries HD 152218 and HD 152248. Comparison of the models with observational data was made for stars below 50 Mʘ . Since there are no studies to calculate internal structure coefficients for stellar models with masses greater than 50 Mʘ, these results will guide the future theoretical and observational studies for very massive stars., Bu tez çalışması Balıkesir Üniversitesi Bilimsel Araştırma Projeler Birimi tarafından BAP 2020/096 nolu proje ile desteklenmiştir.

In the European Union, one of the primary goals of integration is the convergence of the regional income per capita (and of other significant socio-economic indicators), and hence, how to generate a process of convergence. In the economic literature, theories of convergence and divergence examine the reasons for diminishing or increasing the disparities between the rich and the poor re¬gions, and in the case of divergence, explain the persistence of such disparities. In particular, the real convergence approaches are connected to the study of long-term economic growth, economic development and the dynamics of complex economic sectors with high economic and social impacts, and also to the supporting/unsporting institutions and economic mechanisms (market structure, distribution of economic results). Concomitantly, the structural convergence has deserved less attention; although it is an important process for both building and functioning of the single economic and monetary area and for the development of the Member States and their regions. Studies have found that there is a correlation between structural convergence and income (real) convergence, though the findings differ in what regards the strength and direction of such a connection. Starting from the concepts of real and structural convergence, the paper presents an analysis of the real and structural convergence processes in the Romanian counties during the pre-accession and post-accession periods, based on specific indicators (GDP per capita, gross speed of convergence, variation coefficient, gross labor productivity, gross productivity growth rate). Also, with the help of real convergence indices and structural coefficients, the presence and evolution of the relationship between real and structural convergence at sub-regional level is revealed. The results show that the analyzed convergence processes had different speeds in Romania, and that counties have adapted differently to the new economic environment of the EU single market, conditional on their pre-accession development level. The counties which during the pre-accession period recorded good performances have usually strengthened their positions after the EU accession, while the counties with lower performances generally revealed slower growth and convergence, despite recording faster growth rates over certain short periods. Especially regarding productivity convergence, the situation is worrisome for the poorest counties of Romania, but also for some of the counties with higher development level. The real convergence was generally aligned with the structural convergence in the Romanian counties, but again only the most developed counties recorded post-accession progresses in both the convergence processes. Such results are in line with the findings of other studies on the economic and structural convergence of the Member States and/or their regions, but also reveal the sub-regional peculiarities of the catching up and development processes going on in the Romanian economy, and call for more effective implementation of the national and EU development policies at all levels.

El artículo presenta las recomendaciones para el diseño de la estructura de pavimento para la vía de acceso al puente utilizando la metodología AASHTO de 1993 y verificando el diseño mediante el método mecanicista para un periodo de servicio de 10 años, tomando como base las variables y condiciones particulares del proyecto, entre las que se destacan: características de la subrasante existente, camión de Diseño de Ecopetrol, (Camión de 60 Toneladas), tráfico canalizado, velocidad de diseño de 30 km/Hr, temperatura Media Anual de 27.0 ºC. Estas condiciones se analizaron detalladamente toda vez que el comportamiento de la estructura y particularmente las propiedades mecánicas de la carpeta asfáltica están en función de la frecuencia de la aplicación de la carga, (la cual es inversamente proporcional a la velocidad vehicular), temperatura. Teniendo en cuenta que en la práctica se tiene más experiencia en el medio con el manejo de estructuras tipo Mezcla Densa en Caliente – Base Granular -SubBaseGranular y que en la zona de estudio se presentan temperaturas que con el tiempo podrían afectar negativamente el comportamiento dinámico de arreglos estructurales con altos espesores de Carpeta Asfáltica o Base Estabilizada con Emulsión, al ser más factible que se presente ahuellamiento, finalmente se recomienda la construcción de una estructura tipo Mezcla Densa en Caliente – Base Granular -SubBaseGranular para un periodo de diseño de 10 años. The article presents recommendations for the design of the pavement structure for the road to the bridge using the 1993 AASHTO methodology and verifying the design by mechanistic method for a service period of 10 years, based on variables and conditions particular project, among which are: characteristics of the existing subgrade design Ecopetrol truck (truck 60 Tons), channeled traffic, design speed of 30 km/hr, annual temperatura of 27.0ºC. These conditions are discussed in detail given that the behavior of the structure and particularly the mechanical properties of the asphalt are a function of the frequency of application of the load, (which is inversely proportional to the vehicle speed), temperature. Considering that in practice they have more experience in managing medium like structures Asphalt Cement Concrete –Crushed Stone Base-Granular Subbase and that in the study area temperatures are presented that over time could adversely affect the dynamic behavior of structural arrangements with high Folder thicknesses or Base stabilized with Asphalt Emulsion, being more likely to be present rutting finally building a Asphalt Cement Concrete –Crushed Stone Base- Granular Subbase type structure design for a period of 10 years is recommended.

İnlek, Gülay (Balikesir Author), We give new values of the structural coefficients eta(j), and related quantities, for realistic models of distorted stars in close binary systems. Our procedure involves numerical integration of Radau's equation for detailed structural data for stellar models taken from the EZWeb compilation of the Department of Astronomy, University of Wisconsin-Madison.

The economic structure by sectors plays a very important part in the dynamics of development gaps at sub-national level, because it influences the income level and distribution in the regions/sub-regions of a country, as many empirical studies showed. In the perspective of increasing globalization, difficult recovery from economic crises, and persistent inter-country, inter-regions and intra-regional development gaps, the goals of cohesion policy in the EU member states in the future programming period, 2014- 2020, envisage, among others, the best use of regional/local human, natural and capital resources in order to increase the living standard of all citizens and diminish the development imbalances. The paper presents an analysis of the sectoral gross value added dynamics in Romania, its regions and other EU countries with the help of various structural coefficients, in the attempt to identify patterns of sectoral convergence or divergence, structural resilience or fragility and the likely impact of economic crises.

Applying stated preference to destination choice has been little researched, partly because of the need for many more alternatives than could be available with stated preference. However during the course of several successive stated and revealed preference surveys, we have developed a successful experimental design and survey instrument so as to measure destination choice coefficients. We have taken this further so as to deal with the combined choice of destination and toll route. We have used this stated preference and revealed preference experimental design to investigate whether destination choice is above toll route choice or vice versa. This paper traces the different approaches adopted in a series of stated and revealed preference exercises in Nigeria in an attempt to understand this structural relationship between destination and toll route choice and reports on the final successful approach. It presents the detailed estimation results from the successful survey together with the estimated structural parameters using simultaneously estimated nested logit model estimation.
