the present study evaluated effects of 0.0%, 0.5%, 0.75% and 1.0% l-threonine in diet on performance and gastrointestinal tract development in broiler chickens during summer. from 0 to 42 days old, body weight gain was greater in 0.75% l-threonine fed birds than in 0.0% and 0.5% l-threonine fed birds (p0.05). during the growth period, 0.75% l-threonine fed birds had the highest body weight gain...

pollen morphology of some species of the genus malus (rosaceae) was investigatedtaxonomically. all species are characteristic by tricolpate pollens. exine sculpturing is variable but is mostlystriate. however, species may differ in degree of density of ridges and their orientation. the exine patterns inm. trilobata and m. florentina are very similar and were characterized by short and very bran...

patients and methods twenty-two young men (age = 23.34 ± 2.56 years, weight = 72.47 ± 12.01 kg, and height = 174.10 ± 5.75 cm) were recruited and randomly assigned into control (n = 10) and hiit (n = 12) groups. echocardiography was used to evaluate left ventricular mass (lvm), end-systolic volume (esv), end-diastolic volume (edv), interventricular septal wall thickness (ivswt), stroke volume, ...

hottentotta is one of the most widely distributed genera of the family buthidae, with species present throughout africa, the arabian peninsula, and in asia to pakistan and india. recently, kovarik (2007) revised genus of hottentotta in the world and reported 29 different species-group name in the genus of hottentotta. hottentotta is one of the six medical important scorpions of iran that distri...

nanocomposites based on polyamide 6 (pa6) and poly(ethylene-co-1-butene)-graft-maleic anhydride (eb-g-mah) blends have been prepared via melt mixing. the effect of blend ratio and organoclay concentration onthe crystallization and melting behavior of specimens were studied. three types of commercial organo-modifiedclay (cloisite 30b, cloisite 15a and cloisite 20a) were employed to assess the im...

copper thin films with nano-scale structure have numerous applications in modern technology.  in this work, cu thin films with different thicknesses from 50–220 nm have been deposited on glass substrate by dc magnetron sputtering technique at room temperature in pure ar gas. the sputtering time was considered in 4, 8, 12 and 16 min, respectively. the thickness effect on the structural, morpholo...

the mechanism and the parameters affecting the matrix-fibril morphology in melt spun polyblend fibers are discussed. the properties of polymeric blends depend considerably on their final morphologies. blending of two miscible polymers, normally gives rise to formation of a single-phase morphology while blending of two immiscible polymers can create a two or three (in case of using compatibilize...

This is a working paper, describing work that the two of us have done over the course of 2016 and the beginning of 2017, developing in some detail an analysis of some aspects of inflectional morphology. In most respects this work continues the development of work in this area over the past fifty or more years, but in one or two important ways our approach is different. We believe that a geometr...

In the early years of the development of a theory of generative grammar (roughly 1955 through the early 1970s), a striking difference between the research problems that characterized the emerging field and those that had occupied its predecessors was the precipitous decline of the study of morphology. The principles of word structure can be divided roughly between those that govern the distribu...
