3.1 Abstract Rheological behavior of reactively extruded starch-PCL nanocomposite blends was evaluated in an off-line capillary rheometer. Power law models for blends with different nanoclay volume fractions were developed using appropriate correction factors. Consistency coefficients K for blends containing starch were significantly higher than 100% PCL. Starch-PCL nanocomposite blends showed ...

Why process at all? Of course, the answer is ultimately feed efficiency, producing the most milk, eggs, meat or fiber at the lowest possible cost. Particle size reduction as the first step in the feed manufacturing process works toward the goal of improved feed efficiency by increasing the surface area of the materials being processed. This increases the amount of materials exposed to the anima...

A rotary vane expander has been developed to replace the throttling valve for improving the COP of transcritical CO2 refrigeration system. Due to the serious internal leakage, the expander efficiency is not satisfactory. This paper presents the theoretical and experimental investigation on the internal leakage in a rotary vane expander prototype. Firstly, the leakage flow rate through the inter...

BACKGROUND The optimum protocol for expander volume adjustment with respect to the timing and application of radiotherapy remains controversial. METHODS Eighteen New Zealand rabbits were divided into three groups. Metallic port integrated anatomic breast expanders of 250 cc were implanted on the back of each animal and controlled expansion was performed. Group I underwent radiotherapy with fu...

In this work, we present the first local-decoding algorithm for expander codes. This yields a new family of constant-rate codes that can recover from a constant fraction of errors in the codeword symbols, and where any symbol of the codeword can be recovered with high probability by reading N symbols from the corrupted codeword, where N is the block-length of the code. Expander codes, introduce...

In this paper, a Rankine cycle test system is established to recover exhaust energy from a 2.0 L gasoline engine. Experiments on the system’s performance are carried out under various working conditions. The experimental results indicate that the recovery power of the expander is strongly related to the load and speed of the gasoline engine. It is found that when the output power of the gasolin...

A hybrid expander is a newly designed bone-anchored expander consisting of 2 mini-screws and palatal acrylic; it does not cover any teeth. The aim of this case report is to present the treatment of a patient with transversal maxillary deficiency by hybrid expander. An 11.4-year-old female patient came to our clinic complaining about the appearance of her teeth. She had a narrow maxillary arch, ...

Objective: To present skeletal class III patient treated with protraction face mask and bonded rapid maxillary expander in order to demonstrate the effects of face mask and bonded rapid maxillary expander on maxillary hypoplasia skeletal class III patient. Materials and methods: The patient was reported with skeletal class III malocclusion. The patient was 11 year 3 month old boy and his treatm...
