in this research, tested factors were margarine types (contractive effects between types of oils in base of margarine such as palm super olein – partially hydrogenated canola oil – 50:50 mixture of palm super olein and partially hydrogenated canola oil and liquid canola) and different moisture (16-8-4%) as the first factor and heating time is the second factor. every margarines spend 3 times he...
compound (n,n-bis (salicylidene) 1,2-diaminophenylene) was prepared by condensation of ethanolsolution of 2-hydroxybanzaldehyde and 1,2-diaminophenylene. the compound was characterized by1h nmr, infrared spectroscopy (ft-ir) data and analytical data. the geometrical parameters andenergies have been obtained from density functional theory (dft) b3lyp method and hartree-fock (hf) method with 3-21...
in the present study, aqueous solutions of some copper-complexing ligands were screened for their cytotoxicity using brine shrimp lethality test. among the ligands tested, diacetyl-bis(n4-methylthiosemicarbazones) (atsm) proved to be the most safe and non-toxic compound (2% lethality at 10 ppm), while pyruvaldehyde bis(n4-methyl)thiosemicarbazone (ptsm) was shown to possess low toxicity (7% let...
This paper describes compound reinforcement learning (RL) that is an extended RL based on the compound return. Compound RL maximizes the logarithm of expected double-exponentially discounted compound return in returnbased Markov decision processes (MDPs). The contributions of this paper are (1) Theoretical description of compound RL that is an extended RL framework for maximizing the compound r...
Cancer is a big global problem and is one of the top and main causes of mortality in developed countries. Many of the current treatments and anticancer therapeutics have problems with severe side effects and on the other hand, the drug resistance is also another obstacle in the cancer chemotherapy. Hence, there is a strong demand for the discovery and development of effective new antineopla...
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...
