abstract in order to evaluate the effect of testa on reduction of fungal growth and aflatoxin b1 producthon, ten cultivars of pistachio were collected from different parts of pistachio belt i-e rafsanjan, damghan and ghazvin of iran. a section of testa and one mm of endosperm were scraped. 20 gr. of wounded kernels and 20 gr. of unwounded kernels were surface sterilized and then placed in petri...

In this paper we aim to measure and to explain the frontier total factor productivity (TFP) growth in Tunisia over the period 1983-1996. We do not measure TFP growth by the conventional Solow residual. Instead we define TFP growth as the shift of the economy's production frontier, which we obtain year by year by solving a linear program, a sort of aggregate DEA analysis. We then decompose this ...

Based on a framework proposed by Battese and Coelli (1995), we estimated the stochastic frontier production function for four Chinese industries: building materials, chemicals, machinery and textiles during 1990–1994. The type of technological change is tested and total factor productivity (TFP) growth is calculated for each industry. We found no evidence of technological change in the building...

In this paper, we focus on the efficiency performance of the Vietnamese commercial banks in terms of their efficiency change, productivity growth, and technological change during the period 2001–2003. We use a data envelopment analysis (DEA) model for this purpose. Productivity is measured using the Malmquist total factor productivity index. The panel data of 13 commercial banks in Vietnam are ...

In this paper, the authors present new indices for estimating technical change, return to scale, and TFP growth, as well as its decomposition. These indices, Modified General Index (MGI), Generalized Modified General Index (GMGI), and General Time Trend index (GTTI), are generalization of General Index approaches. These approaches were used for productivity decomposition of Iran's barely produc...

Technical efficiency (TE) and total factor productivity (TFP) are important criteria to ensure the enhancement of quality state-owned enterprises (SOEs) function as indicators assess their accomplishments. The purpose this study is explore whether SOEs higher or lower than that private enterprises. Transcendental logarithmic production stochastic frontier analysis (SFA) used TE TFP listed centr...

The carob moth, Apomyelois ceratoniae (Zeller) (Lepidoptera Pyralidae), is a serious pest of pomegranate in Iran and a well known pest of many fruits from a wide range of plant families as well as dried fruits during storage. Development and demographic parameters of A. ceratoniae were studied in a growth chamber at temperature of 30 ± 1 °C, relative humidity of 75 ± 5% and a photoperiod of 16:...

The U.K. skill premium fell from the 1950s to the late 1970s and then rose very sharply. This paper examines the contributions to these relative wage movements of international trade and technical change. We first measure trade as changes in product prices and technical change as TFP growth. Then we relate price and TFP changes to a set of underlying factors. Among a number of results, we find ...

a total of ten isolates of fungi with rhizoctonia-like mycelia were obtained from infected roots and stems of pistachio pistacia vera grown in a commercial nursery in rafsanjan, iran, during the autumn of 2011. the infected seedlings showed symptoms of chlorosis that later turned to necrosis. all of the isolates were identified as binucleate rhizoctonia on the basis of hyphal characteristics an...
