The objective of this study was to identify measures appropriate to estimate travel time reliability and apply them to study the reliability of travel time under varying freeway operating conditions. More specifically, a case study was undertaken to study travel time reliability along the I-65 corridor in the State of Alabama. The objectives of this study were to: a) Calculate reliability metri...
طی سالهای 1385 و 1386، علایم لکه برگی روی درختان نارون (Ulmus minor Mill.) واقع در حاشیه رودخانههای اطراف همدان با شدت نسبتاً زیاد مشاهده شد. به منظور جداسازی عامل بیماری قطعاتی از برگهای آلوده پس از ضدعفونی سطحی با هیپوکلریت سدیم 1-5/0 درصد روی محیطهای کشت PDA (potato-dextrose agar, Merck) و MEA (malt extract agar, Merck) قرار داده شدند. مشاهده برگهای آلوده از طریق تهیه مقاطع عرضی با استفا...
The effect of L(+)ascorbic acid and/or sodium nitrate in nitric oxide production by hepatocytes in vitro was studied. It was demonstrated that the compounds added into an incubation medium stimulated nitric oxide production in hepatocytes. The highest concentration of nitric oxide was assayed after the incubation of the cells with sodium nitrate and L(+)ascorbic acid. It was found that the addi...

The alteration of two trioctahedral micas, biotite and phlogopite, was investigated at the meso, micro, nanoscale using three complementary microscopy techniques to better understand mica surface reactivity. In situ ex experiments were performed monitor mineral interface during dissolution in acidic solutions (nitric oxalic acid, pH ∼ 1–2), over a temperature range 25–100°C. inorganic acid used...

prepared by stirring a mixture of 1 with the corresponding carboxylic acid (1.1 equiv.) in the presence of dicyclohexylcarbodiimide (DCC) (1.1 equiv.) and 4-dimethylaminopyridine (DMAP) (0.1 equiv.) in CH2Cl2 at room temperature for 24 hours. The crude products, obtained after usual work up, were purified by preparative TLC on silica gel (Article No. 13794, E. Merck) using CHCl3 MeOH (9:1) as t...
The parameters of the continuous technological process leaching copper from fine waste using nitric acid as an oxidizer are studied. Optimal conditions for a were established, in which solutions with mass concentration ions greater than 25 g/dm3 obtained.
