Introduction: The orbit has a fine bony structure and represents the most vulnerable in cranium. Therefore, penetrating orbital injuries are often associated with traumatic brain injury. Although transorbital-penetrating intracranial injury is not commonly encountered emergency medicine practice, this occurrence potential to cause severe fatal 
 Case Report: In study, we report case of 21-...
Two experiments examined listeners' ability to discriminate the geometric shape of simple resonating bodies on the basis of their corresponding auditory attributes. In cross-modal matching tasks, subjects listened to recordings of pairs of metal bars (Experiment 1) or wooden bars (Experiment 2) struck in sequence and then selected a visual depiction of the bar cross sections that correctly repr...
The destruction of renal parenchyma caused by excess deflection of the sheath was examined to determine at what level of force the renal parenchyma was ruptured during PNL. The kidney obtained from right nephroureterectomy due to renal pelvic cancer (stage T2N0M0) of a 54-year-old female patient was punctured at the posterolateral portion with a puncture needle. The tract was dilated up to 26 F...
High capacity, high selectivity, and low-cost regeneration conditions are the most important criteria by which new adsorbents for post-combustion carbon dioxide capture will be judged. The incorporation of N,N0-dimethylethylenediamine (mmen) into H3[(Cu4Cl)3(BTTri)8 (CuBTTri; H3BTTri 1⁄4 1,3,5-tri(1H1,2,3-triazol-4-yl)benzene), a water-stable, triazolate-bridged framework, is shown to drastical...
In this paper, we systematically investigated the structural and magnetic properties of CrTe by combining particle swarm optimization algorithm first-principles calculations. By considering electronic correlation effect, predicted ground-state structure to be NiAs-type (space group P63/mmc) at ambient pressure, consistent with experimental observation. Moreover, found two extra meta-stable Cmca...
The use of iron-containing metal surfaces, Fe, Fe-Cr-alloy and stainless steel, for the synthesis of mixed metal Ru-Fe compounds has been studied. The studied process was reductive carbonylation of RuCl3 in the presence of a metal surface. Reactions were carried out in ethanol solutions under 10-50 bar carbon monoxide pressure at 125 degrees C using an autoclave. During the reaction the metal s...
Heteronuclear complexes are highly active catalysts in alternating ring opening copolymerizations (ROCOP) of cyclohexene oxide (CHO)/carbon dioxide or CHO/phthalic anhydride (PA). In this contribution, a series new trinuclear is investigated through structure activity study that reveals the influences ligand electronic properties and metal selection over catalytic linkage selectivity. The faste...
foodstuffs analysis is very important due to population growth and increasing consumer demand for safety and nutritional excellence. the analysis of different compounds in foodstuffs is so difficult without using sample preparation techniques. traditional techniques require large amounts of toxic organic solvents. as a result, they are not only expensive but also environmentally unfriendly and ...
