I. A Gravimetric Method for the Determination of Sodium

A Simple Gravimetric Method for the Determination of Urinary Potassium

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

Development of the Ion Exchange-Gravimetric Method for Sodium in Serum as a Definitive Method

An ion exchange-gravimetric method, previously developed as a National Committee for Clinical Laboratory Standards (NCCLS) reference method for the determination of sodium in human serum, has been re-evaluated and improved. Sources of analytical error in this method have been examined more critically and the overall uncertainties decreased. Additionally, greater accuracy and repeatability have ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Gravimetric Method for the Determination 0f Sodium Pregnandiol Glucuronidate (an Excretion Product of Progesterone) by Eleanor Hill Venning

The isolation and identification of sodium pregnandiol glucuronidate from human urine during pregnancy has been described by Venning and Browne (1) in an earlier communication. Later, Venning, Henry, and Browne (2) reported that, not only is this substance excreted in increasing amounts throughout pregnancy, but it also appears in normal urine during the luteal phase of the menstrual cycle. The...
