the present study is an attempt to investigate the use of vague expressions by intermediate efl learners. more specifically, the current study focuses on the structures and functions of one of the most common categories of vague language, i.e. general extenders. the data include a 22-hour corpus of english-as-a-foreign-language conversations. a comparison is also made between this corpus and a ...

Generalizing Woodin’s extender algebra, cf. e.g. [8], we isolate the long extender algebra as a general version of Bukowský’s forcing, cf. [1], in the presence of a supercompact cardinal.

Dermatologic laser surgery is a continuously evolving field of medicine. According to the American Society for Dermatologic Surgery, in 2003, more than 100 million laser and light source cosmetic procedures were performed by its members. Procedures including hair removal and nonablative treatments, as well as removal of pigmented lesions, tattoos, and unwanted vascular lesions have revolutioniz...

Robot manipulators are designed to perform tasks which would otherwise be executed by a human operator. No manipulator can even approach the speed and accuracy with which humans execute these tasks. But manipulators have the capability to exceed human ability in one particular area; strength. Through any reasonable observation and experience, the human's ability to perform a variety of physical...

An extender is defined to be an active manipulator worn by a human to increase his strength [6]. The human, in physical contact with the extender, exchanges power and information signals with the extender. The human arm, the extender, and the environment comprise the dynamic model of the extender system. In this paper, an expression for system performance is derived to determine the force augme...

Animal origin egg yolk extender has been associated with microbial contamination and interference with microscopic examination. Therefore, replacement of such extender with plant origin compound is inevitable without compromising the desired qualities of an ideal extender. In the current experiment, we compared the effect of soy-based extender (25% and 50%) of five adult Holstein-Friesian bulls...

Combinatorial biosynthesis approaches that involve modular type I polyketide synthases (PKSs) are proven strategies for the synthesis of polyketides. In general however, such strategies are usually limited in scope and utility due to the restricted substrate specificity of polyketide biosynthetic machinery. Herein, a panel of chemo-enzymatically synthesized acyl-CoA's was used to probe the prom...

The influence of different extender osmolality levels and the presence of different cryoprotectants on the postthawed semen’s characteristics and post-thawed plasma membrane integrity of ram spermatozoa were studied. Ram semen was frozen with TRIS-egg yolk based extender according to two-step dilution procedures. The final concentrations of the cryoprotectants: 6% glycerol, 6% 1,2propanediol, 6...

Semen from four Holstein bulls was evaluated to compare effects of four extender treatments on postthaw semen quality. Extender fractions A and B, either heated whole milk or 20% egg yolk-citrate, were combined to yield the extender treatments 1) milk and milk, 2) milk and egg yolk-citrate, 3) egg yolk-citrate and milk, and 4) egg yolk-citrate and egg yolk-citrate. Semen was evaluated at thawin...

the aim of this study was to evaluate the effect of bovine serum albomin (bsa) in stallion semen extender in cool condition. after collection, semen samples were pooled and divided into four equal parts. each part was diluted with one of the following extenders: 1) extender without bsa (bsa-0), 2) extender containing 5 mg/ml bsa (bsa-5), 3) extender containing 10 mg/ml bsa (bsa-10), and 4) exte...
