A SIMPLE PORTABLE APPARATUS FOR CONTINUOUS OXYGEN ADMINISTRATION

A Portable Apparatus for the Determina- Tion of Oxygen Dissolved in a Small Volume of Water

It is clear from the equations that each atom of oxygen in solution finally liberates one molecule of iodine. The iodine is titrated against sodium thiosulphate solution using starch as indicator; 1 c.c. of normal sodium thiosulphate solution corresponds to 8 mg. of oxygen, or 5-6 c.c. of oxygen at N.T.P. A number of modifications of the original technique of Winkler has been described. The acc...

A simple, inexpensive, portable apparatus for injecting experimental chemicals in drip irrigation systems.

The loss of 1,2-dibromo-3-chloropropane (DBCP) as a postplant nematicide created a serious void in nematode protection for crops nationwide. An acceptable replacement for DBCP is needed, especially on susceptible perennials such as grapes, Vitis vinifera L. Phases of our postplant nematicide research were conducted in commercial vineyards where nematode disease existed on established vines wate...

A Simple Anæsthetic Apparatus

In the apparatus about to be described I make no claim to originality in design. It has been my endeavour to find the simplest form of anaesthetic apparatus which could, with slight adaptation, be used with reliability for intra-tracheal, intra-pharyngeal, or intra-nasal induction using ether with air or oxygen. This apparatus has been in constant use for the past 33r years in certain Indian mi...
