A Research on Nonendangered Population Protection Facing Biological Invasion

Challenges facing child protection.

The challenges facing children in the 21st century are immense and will need to be faced if we are to achieve the goal of child protection for all. Three specific constraints on child protection are examined in this article, namely poverty, HIV/AIDS infection, and war. The authors use their experience in Africa to raise issues of resilience and adaptation, dangers to child protection programs, ...

Challenges Facing Educational Research

Facing the broader dimensions of biological invasions

Invasive species are an excellent opportunity to think about the nature society desires, particularly in the face of global changes. Nature, and human views of nature, are rapidly evolving; our approach to biological invasions through biosecurity institutions and land management policies must evolve in tandem with these changes. We review three dimensions that are insufficiently addressed. Firs...

Atomic Force Microscopy Application in Biological Research: A Review Study

Atomic force microscopy (AFM) is a three-dimensional topographic technique with a high atomic resolution to measure surface roughness. AFM is a kind of scanning probe microscope, and its near-field technique is based on the interaction between a sharp tip and the atoms of the sample surface. There are several methods and many ways to modify the tip of the AFM to investigate surface properties, ...

A Case Study Of A Biological Invasion

One of the most amazing biological phenomena that has occurred in our life time is the introduction and spread of the African honey bee (AHB) in the western hemisphere. Within 50 years of its initial introduction into Brazil, the AHB has colonized much of the New World, giving rise to one of the most rapid and spectacular biological invasions humans have ever witnessed. A remarkable feature of ...
