Companies’ realized earnings depend on overall economic conditions. Market participants should therfore adjust their earnings expectations to surprising macroeconomic news. However, despite its importance for asset pricing models, thus far, empirical research was not able to provide clear-cut evidence of a link between earnings expectations and economic news. Based on a detailed analysis of the...

An in vitro model of persistent infection of mouse fibroblasts (McCoy cells) with a trachoma strain (G17) of Chlamydia trachomatis has been developed. Persistently infected cultures were established by infecting McCoy cells with high multiplicities of chlamydiae. After the first cycle of chlamydial replication, the host cells multiplied more rapidly than the parasites, so that the fraction of i...

Capital Asset Pricing Model (CAPM) is most widely used popular method analysis investment projects, valuation, firm mergers acquisitions, initial public offerings, secondary offerings. The premium CAPM defined as difference between exp...

Abiotic stress decreases crop production worldwide. In order to recommend suitable genotypes for cultivation under water deficit and heat conditions, an overall understanding of the genetic basis plant responses these stresses their interactions with environment is required. To achieve goals, multitrait genotype-ideotype distance index (MGIDI) was utilized recognize abiotic-stress-tolerant whea...

the yield performance of 23 barley (hordeum vulgare l.) genotypes in sixteen test environments across a barley growing region of china was evaluated. the experiment was conducted using a randomized complete block design with three replicates, in two cropping seasons (2010-2011, in the south; 2012-2013, in the north). the gge biplot was applied to analyze the data obtained in the multi-environme...

Plasminogen activator inhibitor (PAI-)1 is associated with cancer progression, fibrosis and thrombosis. It is expressed in the stomach but the mechanisms controlling its expression there, and its biological role, are uncertain. We sought to define the role of gastrin in regulating PAI-1 expression and to determine the relevance for gastrin-stimulated cell migration and invasion. In gastric biop...

The research investigation was carried out in the experimental area of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207, during the late Rabi season Mid December to May 2018 to study genetic variability and character association yield components in Maize with 35 maize genotypes as experimental materials that were laid in Randomized Complete Block Design (RCBD) three r...

But when the forecast horizon is greater than the frequency...

A field experiment was conducted in the experimental field of Genetics and Plant Breeding Department, Sher-e Bangla Agricultural University, Dhaka, Bangladesh to study variability in 10 F4 lines obtained through intervarietal crosses along with 8 released varieties of Brassica rapa. Significant variation was observed among all the genotypes for all the characters studied. Considering genetic pa...
