ABSTRACT Objective To study the effects of contusion and exhaustive exercise on expression degradation-related factors MuRF1 MAFbx in skeletal muscle rats describe repair mechanism injury. Methods Forty-two male SD were randomly divided into 7 groups. The each group killed at different time points (0h, 24h, 48h) after (E0, E24, E48) (D0, D24, D48), respectively, resting state control (C). right...
When we allow capital depreciation to be endogenous, the acceleration of investment-specific technological progress can distort the measurement of the aggregate capital stock. Our quantitative exercise shows that this effect may cause a substantial bias in the measurement of total factor productivity and can account for a large portion of the observed productivity slowdown since the 1970s. 2006...
منطقه اللهیارلوی لاهرود در شمال شرق مشکین شهر به صورت تاقدیسی با روند عمومی غرب، شمال غرب – شرق – جنوب شرق در محدوده های با عرض های جغرافیایی 52َ o38 تا 58َ o38 شمالی و طول های جغرافیایی از 35َ o47 تا 51َ o47 شرقی واقع شده است.براساس مطالعات پتروگرافی سنگ-های دگرگونی منطقه شامل آمفیبولیت ها و متاسدیمنت ها می- باشند. ترکیب کانی شناسی شاخص آمفیبولیت ها شامل هورنبلند، ترمولیت- اکتینولیت وکانی شناسی مت...
Using a new dataset on imports of technology and total factor productivity (TFP) over more than a century for the OECD countries, this paper tests for international technological transmission through trade. The empirical estimates suggest that imports of knowledge have been responsible for an almost 200% increase in TFP over the past century, but that the spillover effect has been highly uneven...
Abstract Introduction There is substantial evidence linking NF-κB and cancer-related processes. The aim of this study was to investigate the role IKKα, main catalytic component non-canonical pathway in colorectal cancer (CRC). Method Immunohistochemistry immunofluorescence used examine expression IKKα 1030 patients undergoing resection for stage I-III CRC. To assess inhibition, organoids were p...
Halotolerant bacteria are regarded as effective oil-scavengers in the polluted saltern and seawater. In this regard, a halotolerant Planococcus was isolated from oilcontaminated area of Dezful north springs, Iran, due to its capacity in biosurfactant (BS) production. To facilitate hydrocarbons degradation, in the current study, the efficiency of BS production as function of growth rate of the h...
Researchers of regional and international productivity comparisons are increasingly adopting various frontier approaches to examine convergence and the possible causes of productivity differences. We argue that economy-wide technology frontiers estimated with aggregate measures of output are downward biased. This bias extends not only to estimates of the technology frontier, but also produces i...
Technology Spillover through Trade and TFP Convergence: 120 Years of Evidence for the OECD Countries
Using a new dataset on imports of technology and total factor productivity (TFP) over more than a century for the OECD countries, this paper tests for international technological transmission through trade. The empirical estimates suggest that imports of knowledge have been responsible for an almost 200% increase in TFP over the past century, but that the spillover effect has been highly uneven...
Two approaches taken to the embodiment question are compared and discussed: quantitative theory and traditional growth accounting. The two approaches give very different estimates for the contribution of investment-specific technological advance to economic growth. Therefore, the approach taken matters. It is argued that the measures used in traditional growth accounting to gauge the importance...
We study whether the effects on registered manufacturing output of dismantling the License Raj — a system of central controls regulating entry and production activity in this sector — vary across Indian states with different labor market regulations. The effects are found to be unequal across Indian states with different labor market regulations. In particular, following delicensing, industries...
