Experimental data for density, viscosity, refractive index and surface tension are reported, for the first time, in the temperature range between 288.15 K and 353.15 K and at atmospheric pressure for two protic ionic liquids, namely 2-(dimethylamino)-N,N-dimethylethan-1-ammonium acetate, [N11{2(N11)}H][CH3CO2], and N-ethyl-N,N-dimethylammonium phenylacetate, [N112H][C7H7CO2]. The effect of the ...

We have measured the polarization of fluorescence emitted by the noble gases He, Ne, Ar, Kr, and Xe following impact excitation by polarized electrons. In He, the 3P→2S transition was studied; in the heavy noble gases the np(n11)p D3→np(n11)s P2 transitions were analyzed. We investigated these transitions as candidates for efficient optical electron polarimetry and found that, because of their ...

The subcomponents of the cervical evoked response, N11, N13, N14, and the following positivity, were studied in 13 patients with full arrest of the intracerebral circulation, isoelectric EEGs and abolished cortical somatosensory evoked responses. The peak negativity (N13) and the following positive wave were present in all patients. Also N11 and N14 could be identified in most patients either a...

introduction: constipation is one of the most common pediatric disorders.in many cases, there is no anatomic endocrineor metabolic cause in explanation of chronic constipation.more than 85% of them called functional or idiopathic.constipation is one of the serious disease in iranian traditional medicine. besides the problem it causes, chronic constipation can be the origin of many disease. that...

Chiral auxiliary-mediated dynamic resolution of α-halo esters has been known as an effective method for asymmetric synthesis of α-heteroatom substituted carboxylic acid derivatives. While the synthetic method can achieve a useful level of stereoselectivity, it is still of interest to find novel ways to utilize the dynamic resolution for practical synthesis. We have previously reported L-malate-...

The Antarctic is a potentially important library of microbial resources and new bioactive substances. In this study, microorganisms were isolated from surface water samples collected from different sites of the Antarctic. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay-based cytotoxicity-tracking method was used to identify Antarctic marine microorganism resources f...

The hyperparameter in image restoration by the Bayes formula is an important quantity. This communication shows a physical method for the estimation of the hyperparameter without approximation. For artificially generated images by prior probability, the hyperparameter is computed accurately. For practical images, accuracy of the estimated hyperparameter depends on the magnetization and energy o...

PURPOSE Chronic inflammatory processes contribute to the pathogenesis of many age-related diseases. In search of anti-inflammatory foods, we have systematically screened a variety of common dietary plants and mushrooms for their anti-inflammatory activity. METHODS A selection of 115 samples was prepared by a generic food-compatible processing method involving heating. These products were test...
