The liquefaction vulnerability of soil is generally related to a few parameters which are ordinarily measured by laboratory tests on distributed and undistributed under distinctive test conditions. This study uses methods based standard penetration assess criteria appraise the for deposits Chalus City placed in high seismic area. To overcome deficiencies these experimental strategies an ANN-bas...

BACKGROUND T-2 toxin is a mycotoxin that is produced by the Fusarium fungi. Consumption of food and feed contaminated with T-2 toxin causes diseases in humans and animals. OBJECTIVES In this study T-2 toxin was analyzed in poultry and cattle feedstuff in cities of Mazandaran province (Babol, Sari, Chalus), Northern Iran. MATERIALS AND METHODS In this study, 90 samples were analyzed for T-2 ...

in this study species richness of earthworms in the central elburz mountains is reported for the first time based on samples collected from 33 localities along the haraz and chalus rivers. twelve species were identified representing seven genera from family lumbricidae (rafinesque-schmaltz 1815): aporrectodea caliginosa (savigny 1826), a. rosea (savigny 1826), a. jassyensis (michaelsen 1891), d...

some biological characteristics of broodstock and juvenile kutum, rutilus kutum. were investigated using data collected from the estuaries of tajen and shirood rivers (tr and sr) (southern caspian sea basin) as well as from the caspian sea in 2012. the results showed higher condition factors (cf) in the male broodstocks kutum than those estimated in the female broodstock of both tr and sr. the ...

A large amount of accurate river cross-section data is indispensable for predicting river stages. However, the measured river cross-section data are usually sparse in the transverse direction at each cross-section as well as in the longitudinal direction along the river channel. This study presents three algorithms to resample the river cross-section data points in both the transverse and longi...

In this study, the generalized linear model (GLM) and four ensemble methods (partial least squares (PLS), boosting, bagging, Bayesian) were applied to predict forest fire hazard in Chalus Rood watershed Mazandaran Province, Iran. Data from 108 historical events collected through field surveys as basis of analysis. About 70% data used for training models, while remaining 30% was testing. A total...

OBJECTIVES To examine nonylphenol (NP) and 4-t-octylphenol (OP) concentrations and general water quality indicators along a river in the greater Tokyo area and to specify the distribution and origin of alkylphenols. METHODS Water was sampled from the Edogawa River, a main river in the greater Tokyo area, which is a source of public drinking water; and the Sakagawa River system, a tributary of...

Karun River is the largest and most watery river in Iran. This river is the longest river which located just inside Iran and Ahvaz Metropolis drinking water supplied from Karun River as well (fa.alalam.ir). Karun River as the main source of water treatment plants in Ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

Original scientific paper Studies on the evolution of paleo-channels in coastal areas are important for submarine engineering construction and to reveal changes in the global paleoenvironment. Thus, to explore the characteristics of paleo-channels during the late Last Glaciation in the western South Yellow Sea, digital terrain analysis method and ArcGis river extraction function were employed, ...
