language learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Total Knee Replacement Sizing: Shoe Size Is a Better Predictor for Implant Size than Body Height
Background: Various sizes of implants need to be available during surgery. The purpose of this paper is to comparebody height and shoe size with implant sizes in patients who underwent total knee replacement surgery to see whichbiomarker is a better predictor for preoperative planning to determine implant size.Methods: A total of 100 knees, belonging to 50 females and 50 males, were observed. P...
متن کاملEvolutionary trends in body size of parasitic flatworms
Evolutionary trends in body size have been identified within several lineages, but not all have followed Cope’s rule, which states that average body size within a taxon tends to increase over time. In organisms such as parasites, space constraints may have shaped the evolution of body sizes, favouring small-bodied taxa capable of exploiting new niches. Here, the average adult body sizes of fami...
متن کاملEco-energetic consequences of evolutionary shifts in body size.
Size imposes physiological and ecological constraints upon all organisms. Theory abounds on how energy flux covaries with body size, yet causal links are often elusive. As a more direct way to assess the role of size, we used artificial selection to evolve the phytoplankton species Dunaliella tertiolecta towards smaller and larger body sizes. Within 100 generations (c. 1 year), we generated a f...
متن کاملThe evolutionary history of cetacean brain and body size.
Cetaceans rival primates in brain size relative to body size and include species with the largest brains and biggest bodies to have ever evolved. Cetaceans are remarkably diverse, varying in both phenotypes by several orders of magnitude, with notable differences between the two extant suborders, Mysticeti and Odontoceti. We analyzed the evolutionary history of brain and body mass, and relative...
