a humidity sensor thin film based on nanoporous pbwo4-wo3 composites has been prepared by spin coating technique with different weight ratio of pbwo4 (pb) and wo3 (wo) (pwwo-01, pwwo-82, pwwo-64, pwwo-46, pwwo-28, pwwo-01) and their humidity sensing properties have also been investigated at different relative humidity (rh) in the range of 5% - 98% at room temperature with dc resistance. it is f...

titanium dioxide nanocrystals were synthesized by sol-gel method at room temperature. titanium isoprophoxide and absolute ethanol were used as precursors to prepare the sol. the ph of the solution was adjusted by adding nitric acid and sodium hydroxide solution. the prepared tio2 nanocrystals were annealed at 325°c, 425°c and 525°c respectively. the effect of ph on the surface morphology and st...

india is one of the largest producers of onion in the world producing over 13,920,000 metric tons. storage is a major problem which leads to spoilage, and microbes play an important role in the spoilage. in this present study, biotechnologically important strains have been isolated from the spoiled onions by using appropriate enriched media. two potential strains were isolated and a brief compa...

Due to the fact that assets are recorded at their historical value and they may include unrealized gains (losses), managers may manipulate earnings through the sale of these assets and provide financial information which is not accurate and reliable. The aim of this study is to investigate the relationship between income from asset sales, earnings change and leverage of companies listed on Tehr...

 In this research UF cheese pricing is considered and Pegah, Pak, Kaleh, Rouzaneh and Mihan firms’ data, as five main UF cheese competitive firms of Iran in breakfast cheese competitive market, is used. By using these firm’s sales data, production data and price of each ton of UF cheese in nineteen work-periods (each work-period is 6 months), their sales equations are estimated for each work-pe...

The aim of this study was to evaluate the effect of alkaline and NaCl on functional properties of protein isolated from Lanternfish (Benthosema pterotum). In this study, extraction of fish protein was performed at different concentrations of NaCl (0.5%, 1.5%, 3% and 4.5%) at pHs 10 and 12. The results showed alkaline treatment improved the functional properties and the recovery yield of protein...

We apply Slow Feature Analysis (SFA) to image sequences generated from natural images using a range of spatial transformations. An analysis of the resulting receptive fields shows that they have a rich spectrum of invariances and share many properties with complex and hypercomplex cells of the primary visual cortex. Furthermore, the dependence of the solutions on the statistics of the transform...

This study investigated two major types of metadiscourse markers as used in typical sales contracts, written by English natives and Iranian non-natives. In so doing, 60 sales contracts were selected, 30 written by native English and 30 by Iranian non-natives. Based on Hyland and Tse’s taxonomy, the contracts were codified and classified in terms of the frequency and percentage of the interactiv...

This paper evaluates a more integrated approach of regulation when doing international comparisons and represents the first cross-country study in the South American region in which quality and weather variables have been included in the analysis. A total of 82 electricity distribution firms operating in Argentina, Brazil, Chile and Peru have been analysed for the period 1998-2008. Stochastic f...
