Natural Grafting of Branches and Roots

Feminist Therapy: Roots and Branches

The roots and branches of human altruism.

The authors' rigorous and ingenious programme of work documents young humans' capacity for prosocial action (Warneken & Tomasello, 2009). Their laboratory findings are corroborated by centuries of observational data, spanning cultures, and historical epochs. Two general questions are raised. Firstly, what are the rules of evidence needed in using comparative data to make claims about the evolut...

The Top Quark: Experimental Roots and Branches of Theory

Even before the top quark was discovered by the CDF[1] and DØ[2] experiments in 1995, several of its properties could be deduced from those of its weak partner, the bottom quark. The increment in the measured[3] value of R = σ(e +e−→hadrons) σ(e+e−→μ+μ−) at the b threshold agreed with the predicted δR = 13 , confirmingQ b = − 1 3 . Likewise, data[4] on the front-back asymmetry for electroweak b...

Roots and Branches: Hominid Evolution in a Macroevolutionary Perspective

Microwave Assisted Grafting of Natural Polysaccharides

Polysaccharides are known as natural and renewable feed stock for synthesizing high performance macromolecular materials. The popular, versatile and convenient way to develop polysaccharide is being based on materials used for the grafting of synthetic polymers onto natural polysaccharides. Although the attractive chemical and physical properties of polysaccharide co-polymeric materials, undesi...
