After criticism, more modest cancer genome project takes shape
An expensive federal project to identify the genetic changes that cause cancer is blazing ahead despite loud skepticism from some scientists. The US National Institutes of Health (NIH) is set to begin taking applications for the project in early March.
Informed consent issues hobble cancer genome scheme
There may not be enough tumor samples available for the project.
Compressive and flexural properties of hemp fiber reinforced concrete
The compressive and flexural properties of hemp fiber reinforced concretes (FRC) were examined in this paper. Natural hemp fiber was mixed using dry and wet mixing methods to fabricate the FRC. Mechanical properties of the FRC were investigated. The main factors affecting compressive and flexural properties of the FRC materials were evaluated with an orthogonal test design. Fiber content by weight has the largest effect. The method for casting hemp FRC has been optimised. Under the optimum conditions, compressive strength increased by 4 %, flexural strength increased by 9 %, flexural toughness increased by 144 %, and flexural toughness index increased by 214 %.
