OBJECTIVE To compare the effect of storage on expressed colostrum kept at room and refrigeration temperature in 2 different types of containers (steel and plastic) at different time intervals (0 hours to 7 hours). DESIGN Prospective immunological study. SETTING Maternity ward. METHODS Colostrum was collected from 60 healthy lactating mothers and tested for total and differential cell coun...
A revised procedure for the design of steel plate shear walls is proposed. In this procedure, the thickness of the infill plate is found using equations that are derived from plastic analysis of the strip model, which is widely accepted for the representation of steel plate shear walls. Equations are derived from a basic steel plate shear wall configuration but are shown to be conservative for ...
A multi-objective optimization method for the structural design of horizontal-axis wind turbine (HAWT) blades is presented. The main goal is to minimize the weight and cost of the blade which uses glass fiber reinforced plastic (GFRP) coupled with carbon fiber reinforced plastic (CFRP) materials. The number and the location of layers in the spar cap, the width of the spar cap and the position o...
Plastics product design is very experience dependent process. In spite of various computer tools available on the market, the designer has to rely on personal or supporting experts’ knowledge and experience when designing plastics products. Proposed development of the intelligent advisory system presented in this paper involves two methodologies. “Design for X” strategy will be applied to consi...
Plastic composite supports containing 50% agricultural products (oat hulls, soybean hulls, yeast extract, soybean flour, dried bovine erythrocytes, bovine albumin, and/or mineral salts) and 50% (wt/wt) polypropylene were produced by high-temperature twin-screw extrusion. The research employed two half sets of a five-factorial fractional design (2(5 - 1)) to evaluate the effects of different agr...
The authors applaud A. S. Green, E. Rafaeli, N. Bolger, P. E. Shrout, and H. T. Reis's (2006) response to one-sided comparisons of paper versus electronic (plastic) diary methods and hope that it will stimulate more balanced considerations of the issues involved. The authors begin by highlighting areas of agreement and disagreement with Green et al. The authors review briefly the broader litera...
injection molding is the most widely used process for producing plastic parts.in this process, an important issue is to predict and optimize the warpage before manufacturing. in this paper, a simulation with moldflow software is proposed to optimize the injection molding process. the optimization process aims at minimizing the warpage of the critical injection molding part in which process para...
having observed the costly failures of different cutoff walls, that had been constructed according to the mix design specified by reputable consultants in iran, a research programme was conducted to study the effects of constituent materials on the properties of plastic concrete. the main properties, such as compressive strength, biaxial and triaxial strains, permeability, and modulus of elasti...
BACKGROUND The scope was to review the three main clinical indications in periodontal plastic surgical procedures. AIMS To review the fundamental principles in periodontal plastic surgery, the main surgical designs in flap surgery applied to the treatment of recessions, peri-implant soft tissue deficiencies and soft tissue ridge augmentation, as well as the surgical principles of using autolo...
Different antibiotics have different characteristics but the aspect of antibiotic stability is the main concern of the pharmacist when dispensing the drug. The stability of drug such as chemical stability, physical stability, microbiological stability, therapeutic stability and toxicological stability will ensure its therapeutic effect. There are some factors that may affect antibiotics’ effect...
