New evidence is presented that folic acid in serum binds with low affinity to major serum proteins. This low affinity binding is distinct from the high affinity binding by folate binding protein (FBP), a minor protein which is known to occur in serum with great quantitative variability. These conclusions are based on results obtained by equilibrium dialysis of serum containing only negligible a...

In recent decades, Brazil's borders with other South American countries have been associated with a negative agenda. Public intervention has aimed almost exclusively at guaranteeing national security through a variety of restrictions. In the current century, with a slow but steady shift in the geopolitical paradigm, integration among South American nations has become a priority. Border regions ...

At many circumstances, in heat exchange processes several exchangers were used with different cost laws due to their pressure ratings, materials of construction and exchange3r types. In such circumstances traditional methods of pinch technology can not be led to minimum total annual cost may cause some other disadvantages like more complexity or higher maintenance. In this research work a n...

Polysilanes are known to exhibit the interesting property of σ-bond electron delocalization. By employing optical spectroscopy (UV-vis), it is possible to judge the degree of delocalization and also differentiate parts of the molecules which are conjugated or not. The current study compares oligosilanes of similar chain length but different substitution pattern. The size of the substituents det...

Learning a foreign language entails learner to develop special effort or ways of learning acquire the target effectively. This can be achieved through using appropriate strategies. Thus, this article looks at relationship between vocabulary teaching methods and strategies employed by students teachers in secondary schools. Mixed design was used collect quantitative qualitative data. Data were c...

The long-term import of a fundamental challenge of adolescent social development-establishing oneself as a desirable peer companion while avoiding problematic behaviors often supported within peer groups-was examined in a community sample of 184 adolescents, followed from ages 13 to 23, along with parents, peers, and romantic partners.

For years, urban scholars have underscored the value of pristine and functioning ecosystems, including wetlands, to human life. However, less well-understood is role local government (mainly municipalities) in preserving these especially African cities. Drawing on a Zimbabwean case study utilising Urban Sustainability Framework (USF), this article examines how why Harare municipality has failed...
