A large number and variety of compounds are formed in the process of chlorinating drinking water. The classes of compounds formed include trihalomethanes, haloacetic acids, haloacetonitriles, halophenols, and halopropanones. Many of the compounds have been shown to be toxic and are currently being further evaluated by the U.S. Environmental Protection Agency (EPA). One group of the halopropanon...

Post-harvest operations have been used in order to increase the efficiency of product production. In the case of walnuts, one of the important processes for improving quality is peeling the walnut’ s shell. Because of the amount of walnuts produced in Iran and the necessity to reduce the loss of products, a device for quick removal of the walnut’ s shell is needed. This study examined and compa...

The apparent calcium (Ca) digestibility coefficient (ADC) and true (TDC) of different inorganic sources were determined in laying hens ages. Three Ca tests carried out, each assessing 240 Lohmann Brown lineage distributed a completely randomized design. Nine dietary treatments arranged 3 × factorial design consisting three ages (40, 50 70 weeks) (dicalcium phosphate (DCP) sources, fine (FL) coa...

The present study encompasses a new method to simultaneous analysis, design and optimization of Water Distribution Systems (WDSs). In this method, analysis procedure is carried out using Charged System Search (CSS) optimization algorithm. Besides design and cost optimization of WDSs are performed simultaneous with analysis process using a new objective function in order to satisfying the analys...

twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (lp-le), low protein–high energy (lp-he), high protein–low energy (hp-le) and high protein–high energy (hp-he). results showed that the hp-he diet recorded the highest digestibility coefficients of cp, ee, nfe, nutritive values, ...

It is well-known that the k-wise product of one-way functions remains one-way, but may no longer be when the k inputs are correlated. At TCC 2009, Rosen and Segev introduced a new notion known as Correlated Product secure functions. These functions have the property that a k-wise product of them remains one-way even under correlated inputs. Rosen and Segev gave a construction of injective trapd...

learning rapidly and competently has become a pre-eminent strategy for improving organizational performance in the new knowledge era. improving dynamic learning capability is an exclusive strategy for corporate success in construction industry. thus engineering design firms should implement ol to accomplish a state of readiness for change and develop a competence to respond and identify future ...

Patients with hepatocellular carcinoma (HCC) who respond to sorafenib have been reported to exhibit an increase in the level of des-γ-carboxyprothrombin (DCP) in the blood, subsequent to the initiation of sorafenib treatment. In the present study, the levels of secretion of DCP and DCP with more γ-carboxyglutamic residues (NX-DCP) and the effects of hypoxic conditions were examined in 13 liver ...
