a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...

In this study, we investigated the effects of organic waste and moisture superabsorbent on the amount of available water and delay in moisture equivalent of permanent wilting point (PWP) in soil. In the first phase (soil incubation phase), 12 treatments were studied in a completely randomized design at the Soil Science Laboratory of Science and Research Branch, Tehran. The treatments c...

Commercial activated carbon of coconut shell (CS) was used as the raw material for synthesis graphene like using modified Hummers method. The structure CS is amorphous and contains natural minerals such silica, potassium, magnesium calcium impurities. Prior to use, we carried out a thermal pre-treatment process (heating) on in order remove Pieces were grounded size 200 mesh (CS1), then heated a...

Biofiltration of industrial carbon disulfide (CS2)-contaminated waste air streams results in the acidification of biofilters and therefore reduced performance, high water use, and increased costs. To address these issues, we isolated 16 extremely acidophilic CS2-converting Acidithiobacillus thiooxidans strains that tolerated up to 6% (vol/vol) sulfuric acid. The ecophysiological properties of f...

Exposure to organic solvents frequently causes functional impairment of the central nervous system (CNS). One method to examine the effects of solvent exposure on visual function is flash-evoked potentials (FEPs). Greater knowledge of the role of various neurotransmitters in generating FEP peaks would be beneficial for understanding the basis of neurotoxicant-induced changes. FEP peak N166 is i...

To study the effect of bacterial siderophore on the second crop of maize (SC645) under drought stress conditions, a split-factorial experiment, arranged in a randomized complete block design with three replications was conducted in Faculty of Agriculture, Vali-e-Asr University of Rafsanjan at summer 2014. Sampling time was considered as main factor. Five samplings were performed after imposing ...

The tris(pentafluoroethyl)silanide anion adds to carbonyl compounds Ph(R)CO (R=Ph, H), CS2, and CO2, allowing the isolation of novel negatively charged species like [Si(C2F5)3(η2-OC(R)Ph)]− [Si(C2F5)3(η2-CS2)]−, [Si(C2F5)3(η2-CO3)]−. Details reactions are described by Berthold Hoge et al. in their Research Article on page 12124.

The SDL work was done in the ESTI Sub-Technical Committee SPS3 on a voluntary basis with support of the Permanent Expert Group (PEX) at ETSI and the Technical Committee Methods for Testing and Specification (TC MTS). The SDL was developed in parallel with the INAP protocol standardization with only a little delay. The work started in the middle of 1995 and the SDL model was finished in the midd...
