The concentrations of some heavy metals in sediment from the Sinop coasts of the Black Sea were measured to monitor metal pollution in 2013. The distribution of the heavy metals in sediments of the Black Sea shows a variable pattern. The objectives of the present study were to elucidate the distribution heavy metals such as Cu, Pb, Zn, Ni, Mn, Fe, As, Cd, Cr, Hg and Co in sediment from Sinop co...

The objective of this research is to lift the dormancy seeds S. kunthianum in with a view domesticating them. In experiment we used soaking sulfuric acid for different durations (10 min, 30 min and 1 h). treated were sown transparent germinators. explants obtained then transplanted into pots containing five types substrate (black earth, fine sand, sawdust, mixtures 1/1 sawdust/black earth sawdu...

We examined the invasion rate of virulent and avirulent isolates of the pinewood nematode to Japanese black pine seedlings pretreated with simulated acid rain (SAR) at pH 3 and 2. Pretreatment with SAR at pH 3 reduced the invasion rate of virulent nematodes compared to control seedlings in both juvenile seedlings and 1-year-shoot segments of 3-year-old seedlings. This suggests that acid rain at...

Black shank, caused by Phytophthora parasitica var. nicotianae, is a widespread and destructive disease of tobacco. Crop rotation is essential in controlling black shank. Here, we confirmed that rotating black shank-infested fields with rapeseed (Brassica napus) suppressed the incidence this disease. Further study demonstrated that rapeseed roots have a strong ability to attract zoospores and s...

The present work describes the development of a voltammetric sensor for the selective determination of Acid Green 25 (AG25) hair dye, widely used in commercial temporary hair dyes. The method is based on a glassy carbon electrode modified with multiwalled carbon nanotubes activated in the presence of sulfuric acid, where the anthraquinone group present as a chromophore in the dye molecule is re...

To investigate the effect of polyethylene mulch, and manure on yield and yield components of cantaloupe, a two-year study (2007-2008) was carried out at Ardestan Agricultural Research Station by using split plot randomized based on complete block design with four replications. Three polyethylene mulch levels including clear polyethylene mulch, black polyethylene mulch and control treatment were...

Pomfrets are one of the most ample high priced fisheries of the Bay of Bengal, Bangladesh. The present study featuring the comparison of the life history parameters of three Pomfrets i.e. Silver (Pampus argenteus), Chinese (P. chinensis) and Black (Parastromateus niger) is based on the monthly length frequency data from the commercial landings from July 2015 through June 2016. The length (TL) o...

CdS nanoparticles are II-VI group semiconductor in nature with suitable band gap for photoluminescence and photo-catalyst applications. CdS nanostructures were synthesized via a facile precipitation method in the presence of green capping agents such as starch, glucose, gelatin, salicylic acid in the green solvent of water. The influence of concentration, surfactant, precipitating agent on the ...
