A convenient apparatus for sugar estimation

A convenient apparatus for vertical gel electrophoresis.

‘T1HE INTRODUC”ION of starch gel as an electrophoresis medimn by Smithies k4) arkecl a significant advance in the analysis of serum proteins. The increased resolving power afforded by this medium is indicated by the fact that as many as 30 distinct components can be electrophoretically separated; only 5 or 6 are usually observed on paper or in free-solution electrophoresis. Acrylamide gel (2, 3...

Convenient apparatus for the continuous dehydration of histologic material.

SUAL METHODS OF DEHYDRATING histologic material,such as repeated passages through weak to strong solutions of alcohol, are rather time consuming, and the time lost in the recovery of the solvent has compelled most laboratories instead to discard it after use. Such a practice can amount toenormous expense ofmaterial.Automatic devicesreduce toa minimum the personneland the time requiredfortheirop...

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

A convenient microtitration method for the estimation of amino acids.

This paper presents a convenient micromethod for the estimation of amino acids, based on the reaction with ninhydrin. The ammonia formed in this reaction is determined, after elimination of the interference from ninhydrin with superoxol, by addition of saturated potassium hydroxide, aeration, and titration with standard acid. The application of the reaction with ninhydrin is one of the most spe...
