Studying Substitution of Factors and Economies of Scale Using the Composite Cost Function in Fars Cement Factory [PDF]
International Journal of Management, Accounting and Economics, 2016 It is important to analyze the relationship between inputs and economies in the production due to high share of added value and great contribution of cement industry in national production and construction projects.

Mathematical and Computational Applications, 2020 It is considerably important to calculate the cost efficiency in data envelopment analysis for the efficiency evaluation of decision-making units. The present paper develops the classical cost efficiency model in which all the input prices are constant ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Is Rising Returns to Scale a Figment of Poor Data? [PDF]
While using detailed firm-level data from the private business sector, this study identifies two empirical puzzles: (i) returns-to-scale (RTS) parameter estimates rise at higher levels of data aggregation, and (ii) estimates from the firm level suggest ...

O processo de abertura comercial brasileira e o crescimento da produtividade
Economia Aplicada, 2002 This article analyses the relationship between industrial productivity growth and the Brazilian trade liberalization program that began in 1988. Using a econometric model we estimated total factor productivity adjusted by returns to scale and market ...

DEA-based integrated relationship of returns to scale – an application to road maintenance in Taiwan
Journal of Civil Engineering and Management, 2012 An Integrated Relationship of Returns to Scale (IRRS) associated with multiple-stage Data Envelopment Analysis (DEA) is proposed for identifying the returns to scale (RTS) among decision-making units (DMUs) appropriately and accurately.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Trade, Growth and Increasing Returns to Infrastructure: The Role of the Sophisticated Monopolist [PDF]
We consider a model of international trade with increasing returns in a non-traded input into industry, “infrastructure”, and show that the nature of equilibrium depends crucially on whether the infrastructure provider acts in a “naïve” manner – akin to ...

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
