In this paper, we report on the time dependent DCconductivity response at constant electric field of unfilled low density polyethylene (LDPE) and its composites containing untreated and octylsilane treated silica in ambient and dry atmospheres. The conductivity of both composites decrease with time under dry conditions and increase with time in ambient atmosphere. The dielectric response of dry...

BACKGROUND A new device for sterile docking, the Compodock (Fresenius NPBI Transfusion Technology), was developed for connecting PVC tubing for medical use while maintaining sterility. STUDY DESIGN AND METHODS Sterility of the connections was assessed by welding tubing with a heavy exterior contamination with Bacillus subtilis spores and also by welding in an environment contaminated with aer...

Purpose To determine the effect of night-time working on dry eye signs and symptoms. Methods A total of 50 healthy subjects completed a dry eye questionnaire and underwent clinical examinations including basic Schirmer's test and tear breakup time (TBUT) test on two consecutive days, before and after the night shift (12-hrs night-shift). Results All dry eye symptoms were aggravated signific...

throughout the present research, squash (cucurbita pepo) slices (0.4 cm thickness and 4 cm diameter) were blanched in a steam chamber for 4 min. following cooling to room temperature, the squash slices were dehydrated by use of a hotair dryer, under air temperature of 60°c up to moisture content of 0.1065 kg h2o per kg d.m. squash slices of specified weights were rehydrated by immersion in dist...

Dear Sir,?I read with some concern the notes of K. R. regarding my reference on choline content of milk published in the February 1951 issue of the Gazette. The edible portion of dry skim milk, dry whole milk and fresh milk being common in all the three varieties, how could the choline content in the first two vary by dilution ? It is of course true that a given quantity of dry skim or dry whol...

We propose a simple framework for critic-based training of recurrent neural networks and feedback controllers. We term the critics that are used primitive adaptive critics, since we represent them with the simplest possible architecture (bias weight only). We derive this framework from two main premises. The first of these is a natural similarity between a form of approximate dynamic programmin...

By studying adaptive critic designs (ACD) from the standpoint of practical use in training neural networks , we expect to establish the types of problems for which ACD might be preferable to more established methods. To restrict the scope, we have chosen to concentrate on applying ACD, speciically derivative critics, to the training of recurrent networks 1]. This is actually less restrictive th...

The purpose of this study is to provide an empirical analysis of the relationship between ownership structure of French firms and their value. Using data for 510 French publicly traded firms, the current study provides evidence in support of the entrenchment hypothesis. The results show that large controlling shareholders maintaining grip on control while holding only a small fraction of cash f...
