A dynamic impression is a functional impression that records the functional movement of the patient's own muscle and muscle attachment. This process reduces the number of random factors. This article describes a method for making a special tray using a dynamic impression concept that was made from provisional dentures used for implant healing. The individual tray is used to make a wash-impressi...

The Computational Mass Transfer (CMT) model is composed of the basic differential mass transfer equation, closed by auxiliary equations and the appropriate accompanying CFD formulation. In the present modified CMT model, the closing auxiliary equations in the c2 1c model given by Liu (2003) are further simplified for reducing the computational complication. By this model, the turbulent mass tra...

The purpose of this study was to determine if residents (n = 26) living in an Iowa long-term care facility had differences in food intake at their noon meal and body weight when served traditional tray meal service for 10 weeks compared to being served restaurant-style meal service for 10 weeks. The study also evaluated the facility’s raw food costs of the two meal service styles. Mean meal int...

nowadays distillation is recognized as one of the economical and the most trustable separation methods in chemical, petroleum, gas and petrochemical industries. it is almost used as a first and the most applicable choice in separation methods. in this article the effect of inlet downcomer on the hydrodynamics of industrial sieve tray has been elaborated. the study was carried out by using a 3-d...

making a conservative bridge using a natural tooth pontic with mobile teeth is complicated, time-consuming and sometimes impossible with the current techniques and materials. the aim of this paper is` to describe a new method using special rigid tray technique (srtt) to deal with such difficult clinical cases.

STATEMENT OF PROBLEM Success rates for making fixed prosthodontic impressions based on material and tray selection are not known. PURPOSE The purpose of this clinical study was to compare first impression success rates for 2 types of impression material and 2 impression tray systems. MATERIAL AND METHODS Dual-viscosity impressions were made with a vinyl polysiloxane (VPS) (Aquasil Ultra Mon...

Background: In bilateral partial edentulous condition modified Mc Lean’s Impression technique is most commonly advised, this over impression procedure may be time consuming clinically and possible errors too can be induced while recording. The purpose of this study was to determine the efficacy ofsingle custom tray using medium body elastomeric impression material overmodified Mc Lean’s impress...

Background: Heart valve disease gradually increases the pressure in the heart chambers and impairs heart pumping. It influences on quality of life due to low output, disability, fear, amnesia, anxiety, and depression. Although most of signs and symptoms in patients with heart valve diseases may significantly decrease after valve replacement surgery, there is limited information about the impact...

In general, the objective of distillation control is to maintain the desired products quality. In this paper, the performances of different one point control strategies for an aromatic distillation column have been compared through dynamic simulation. These methods are: a) Composition control using measured composition directly. This method sufferes from large sampling delay of measuring de...
