The effects of lithium sulphate following acute administration to Wistar rats - in therapeutic and toxic doses - were investigated, using as markers the levels and turnover of brain, kidney and liver nucleotides. Adenine- and guanine-dependent nucleotides were assayed concomitantly, using a high- performance liquid chromatographic method. Following acute administration, lithium's effects on 3',...
FLUORESCENT OPTICAL LIQUID-LEVEL SENSOR Jonathan D. Weiss Sandia National Laboratories* Mail Stop 1081 P.O. BOX 5800 Albuquerque, New Mexico 87185-1081 tel: 505-845-8213 fax: 505-844-2991 ernai~:jdwe@%andia.~ov ABSTRACT An optical method of detecting liquid level is presented that uses fluorescence radiation generated in an impurity-doped glass or plastic slab. In operation, the slab is inserte...
In this project, we have worked with an indicator on automatic water level controller. When looked up our topic the internet, realized that most of projects used microcontrollers or IC 555, but didn’t include any these circuits in model. Our design is based LM324N IC, which functions as a rectifier, oscillator, and comparator. On foundation, construct circuit, model successfully executed at min...
BACKGROUND AND STUDY AIMS Endoscopic diagnosis of esophageal achalasia lacking typical endoscopic features can be extremely difficult. The aim of this study was to identify simple and reliable early indicator of esophageal achalasia. PATIENTS AND METHODS This single-center retrospective study included 56 cases of esophageal achalasia without previous treatment. As a control, 60 non-achalasia ...
