Se ha determinado una expresión matemática que demuestra que dos funciones de producción que tienen igual intensidad de uso de factores generan una función de transformación recta si los rendimientos a escala son co...

The ability of ecosystems to maintain their functions after disturbance (ecological resilience) depends on heterogeneity in the functional capabilities among species within assemblages. Functional heterogeneity may affec...

Este trabalho procura mostrar que o termo "funcionalismo", frequentemente suposto como uma abordagem única ou uniforme na lingüística, precisa ser compreendida em suas diversas perspectivas. Inicio o trabalho apresent...

The peculiarities of distribution and use of budgetary facilities for the public goods production in the EU countries, including Poland, are considered and possibilities of adaptation of this experience to the Ukrainian ...

Abstract Camel milk plays a critical role in the diet of peoples belongs to the semi-arid and arid regions. Since prehistoric times, camel milk marketing was limited due to lacking the processing facilities in the camel-...

Local production systems (LPS) focused on biomass usage represent a viable alternative to rural development, which can contribute to solve its socio-economic problems in Slovakia. The main objective of this paper was to ...

The present work aims to update a series of information about the regional fishing production, by presenting and characterizing the contribution of the different sub-systems of the Amazon basin to the catch landed at the...

Estudaram-se o padrão das curvas de lactação de 5.368 vacas F1 Holandês-Gir pelo modelo gama incompleto e os efeitos da ordem de lactação e época de parição sobre os parâmetros da função e sobre a produção ...

ABSTRACT Aims to investigate the effects of grape seed proanthocyanidin extract (GSPE) on production performance, metabolism, and anti-oxidative status of Holstein dairy cattle in early lactation. Forty-eight multiparous...

Tree pruning influences the phenology of fruit species. The present study aimed to evaluate the growth and phenology of the fig cultivar ‘Roxo de Valinhos’ subjected to formative and production pruning in the semi-ar...

The Qinghai–Tibetan Plateau (QTP) is a critical ecological security barrier for China, playing an indispensable role in ecosystem services (ESs). However, comprehensive assessments of the ecological barrier functions o...

We measure, for the first time, the median equivalent width (EW) of H alpha+[N II] in star-forming galaxies at z similar to 8. Our estimate leverages the unique photometric depth of the Spitzer/IRAC 5.8 mu m band mosaics...

Abstract To address the challenge of abnormal tobacco shred detection in cigarette production lines, this study proposes an improved lightweight YOLOv8-based model that balances model efficiency and detection accuracy. F...

Nowadays, in many fields of science it is necessary to carry out miscellaneous analyses using classical statistical methods, which usually have correct assumptions. These assumptions in the research realities cannot alwa...

During ontogeny, complex adaptations undergo changes that sometimes entail different functional capabilities. This fact constrains the behaviour of organisms at each developmental stage. Rodents have ever-growing incisor...

Abstract Fungal histone methylation modification (HMM) includes methylation and demethylation at the histone lysine/arginine residues, which are catalyzed by the methyltransferases (HMTs) and demethylases (HDMs) of histo...

ABSTRACT The objective of this study was to quantify the superovulatory response and embryo production of Brazilian Bergamasca sheep and to evaluate the link to the follicular condition before superovulatory treatment, a...

In the last years, functional foods have awakened consumer, scientific and business interest. A commonly found vegetable in such kind of foods includes garlic (Allium sativum). By its ability for selenium (Se) bio-accumu...

In this paper, we have determined the effect of both muscarinic acetylcholine receptor (mAChR) and exogenous prostaglandin E(2) (PGE(2)) on PGE(2) production and cyclooxygenases (COX) mRNA gene expression on rat cerebral...

The functioning of an industria l enterprise of discrete production is considered as a set of interconnected production аnd design processes and managing them. Computer modeling of processes is used to review options fo...

The article discusses the role of word formation in text production. It is argued that word-forming elements can perform various functions connected with text production. Derivational elements serve as starting structura...

ABSTRACT The objective of this study was to identify types of production system and their main indicators on bioeconomic efficiency, using qualitative and quantitative methods to evaluate beef cattle farms in the western...

Cell-mediated immunity, cytokines induced during the specific immune response and T-cell populations are crucial factors for containing Mycobacterium tuberculosis infection. Recent reports suggest a cross-regulation betw...

ABSTRACT There is an urgent need for sustainable animal production systems. A system or procedure is sustainable if it is acceptable now and if its expected future effects are acceptable, in particular in relation to res...
