Industrial sector is a backbone of the economy throughout world. Despite that there are lot benefits; such as development urbanization, major contributor in economy’s growth sign industrial development. There adverse effects on environment including depletion and damage our natural precious resources. Textile, cement, paper pulp, sugarcane, food, pharmaceuticals, chemical, paint other industrie...

Introduction: The removal of organic precursors of disinfection byproducts (DBPs), i.e. natural organic matter (NOM), prior to disinfection is considered as the most effective approach to minimise the formation of DBPs. Trihalomethanes (THMs) as the main group of DBPs are categorized and considered to have the potentiality of increasing the rate of liver, kidney and CNS adverse effects. Methods...

Light availability inside a forest canopy is of key importance to many ecosystem processes, such as photosynthesis and transpiration. Assessment of light availability and within-canopy light variability enables a more detailed understanding of these biophysical processes. The changing light-vegetation interaction in a homogeneous oak (Quercus robur L.) stand was studied at different moments dur...

The terminase of bacteriophage SPP1, constituted by a large (G2P) and a small (G1P) subunit, is essential for the initiation of DNA packaging. A hexa-histidine G2P (H6-G2P), which is functional in vivo, possesses endonuclease, ATPase, and double-stranded DNA binding activities. H6-G2P introduces a cut with preference at the 5'-RCGG downward arrowCW-3' sequence. Distamycin A, which is a minor gr...

OBJECTIVE Despite a long history of interest in personality as well as in the mechanisms that regulate sleep, the relationship between personality and sleep is not yet well understood. The purpose of this study was to explore how personality affects sleep. DESIGN The present cross-sectional study, based on a sample of 1291 participants with a mean age of 31.16 years (SD = 12.77), investigates...

In this study, first of all, removal of dyestuffs from the wastewater ,which is biologically treated but colour removal is not achieved, was investigated by chemical coagulation (FeCl3, FeSO4 and Al2(SO4)3 coagulants), Fenton oxidation (different volume of peroxide and Fe+2) and ozone oxidation(1 gr/h ozone dose) methods. According to the experimental results, maximum color removal efficiencies...

Although superfine powdered activated carbon has excellent adsorption properties, it is not used in conventional water treatment processes comprising coagulation–flocculation, sedimentation, and sand filtration (CSF) due to concerns about its residual treated water. Here, we examined the production fate of very fine particles with lacking charge neutralization as a source filtrate after CSF tre...

For solving the problem of low efficiency about dyes and slow precipitation rate for powdered activated carbon (PAC), this study successfully prepares a kind carbon-based composites (PACMC) to remove Rhodamine B (RhB) in wastewater as an adsorbent. PACMC derived from potassium humate polyaluminium chloride (PACl)-modified PAC were fabricated via chemical method. We confirmed micro-morphology co...
