Microsatellites are promising genetic markers for studying the demographic structure and phylogenetic history of populations. We present theoretical arguments indicating that the usefulness of microsatellite data for these purposes may be limited to a short time perspective and to relatively small populations. The evolution of selectively neutral markers is governed by the interaction of mutati...

In her article "Virtuality, Nationalism, and Globalization in Zhang's Hero" Ping Zhu examines how Yimou Zhang's martial arts film dislodges the historical tale from its spatiotemporal context by creating virtual images, characters, narratives, and ideologies, and presents the virtual idea of tianxia (天下) (all under heaven) as an active mode of participation in the virtual global. Amidst the sur...

all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...

for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...

Journal: :Cities 2022

The rapid growth of cities—along with the increasing connectedness world's social, economic, and political systems—has been hypothesized to generate a homogenization urban form associated environmental impacts. These hypotheses, however, have rarely tested. Employing satellite imagery 150 most populous cities in China, India, United States, we examine how area configuration built-up land within...

To test whether quantitative traits are under directional or homogenizing selection, it is common practice to compare population differentiation estimates at molecular markers (F(ST)) and quantitative traits (Q(ST)). If the trait is neutral and its determinism is additive, then theory predicts that Q(ST) = F(ST), while Q(ST) > F(ST) is predicted under directional selection for different local o...

Abstract-An examination was made of the effect of changes in the osmolarity and the ionic composition of the homogenizing medium on the partition of lysosomal arylsulphatase and N-acetylglucosaminidase of cerebral cortex, hypothalamus and thalamus of the rat. Sulphatase appeared to be more sensitive to hypotonicity than glucosaminidase, since a higher proportion of the sulphatase was released f...

in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...

Aqueous Zinc-Ion Batteries In article number 2203542, Chuan Wu, Ying Bai, and co-workers develop a unique strategy to achieve aqueous Zn metal anodes with long lifespan, deep plating/stripping ability high current tolerance. A microporous artificial layer alleviates the side reactions by repelling sulfate groups, inducing deposition preferred orientation homogenizing ion flux dendrite-free morp...
