I have developed "tennis elbow" from lugging this book around the past four weeks, but it is worth the pain, the effort, and the aspirin. It is also worth the (relatively speaking) bargain price. Including appendixes, this book contains 894 pages of text. The entire panorama of the neural sciences is surveyed and examined, and it is comprehensive in its scope, from genomes to social behaviors. The editors explicitly state that the book is designed as "an introductory text for students of biology, behavior, and medicine," but it is hard to imagine any audience, interested in any fragment of neuroscience at any level of sophistication, that would not enjoy this book. The editors have done a masterful job of weaving together the biologic, the behavioral, and the clinical sciences into a single tapestry in which everyone from the molecular biologist to the practicing psychiatrist can find and appreciate his or

Ti-6Al-4V powder, produced by the hydride-dehydride (HDH) process, was hot isostatically pressed (HIP) into three bars. The 10 cm (4 in) diameter bars were hot worked (HW) to three different diameters: 5.1 cm (2 in) (75% reduction in area), 3.8 cm (1.5 in) (86% reduction in area), and 2.5 cm (1 in) (94% reduction in area). Three samples were machined out of each bar along the end, middle and transverse orientations. These samples were ground, polished, and etched. The microstructure of the samples was evaluated at 100X and 200X magnifications. The objective of this experiment was to examine the effect of deformation on the microstructure and properties of hot rolled titanium alloy bar product. Charpy impact samples were also machined out of each of the various diameter bars. Impact testing was used to quantify toughness by correlating the microstructure to the energy absorbed. The tensile properties of the hot bars were determined as well as the crystallographic texture. Scanning electron microscopy (SEM) was performed on the fractured surface of the Charpy impact samples.

Phase transformations, morphology, and crystallographic texture evolution in hot and cold-rolled Ti-2551 wt% Nb alloys are investigated The experimental procedure involves synthesis of the alloy by arc melting followed by cold or hot rolling with intermediate prior and postheat treatments Composition and phase analysis of all alloys are conducted using x-ray diffraction techniques and microstructural observations are conducted using an optical microscope These examinations reveal that the as-melted alloy possesses large millimeter size grains with no stored strain energy and a two phase β − α′ microstructure Direct cold rolling followed by a short homogenization leads to a β − α′′ mixture with ω precipitates Two hour annealing before cold rolling leads to an α′ − α′′ mixture with a characteristic triangular martensitic microstructure evidencing the act of shear on formation of the phase Hot rolling followed by a water quench results in a β − α′′ mixture, while annealing prior to hot rolling transforms the arc-melted material to a α′ − α′′ mixture The crystallographic textures of similar microstructure mixtures in hot and cold-rolled samples are distinctively different The analysis shows that the microstructure serves as an identifying characteristic of the processing paths and is highly dependent on the mode of processing

Microstructural Evolution in Hot and Cold-Rolled Ti-Nb Alloy

This paper examines grain boundary sliding under the conditions of plastic strain incompatibility that is the most frequent case in polycrystalline materials. Two components of grain boundary sliding: dependent and independent on intragranular slip are distinguished. Theoretical estimate of a ratio between slip induced sliding and intragranular slip is obtained. It is concluded that slip and sliding are rather independent than interrelated processes.

On the Relationship Between Grain Boundary Sliding and Intragranular Slip During Superplastic Deformation

Design of materials and devices by mimicking the fascinating systems found in nature, have enabled scientists to discover new techniques to treat diseases from diagnosis to therapeutic care. With the recent advances in nanomedicine, the length-scale of this design has further extended down into a nano-sized array. Inspired by the two natural assemblies found in nature; cellulose and collagen; we have designed a new class of green functional material with nano-sized arrangement. The fabricated material composed of collagen hydrogel reinforced by cellulose nanowhiskers in order to effectively enhance the rigidity of collagen and to better mimic the morphology and profile features existed in biological tissues. The biocompatibility of the hydrogel nanocomposite was also investigated by the invasion and proliferation of human bone marrow derived mesenchymal stem cells around the materials at 8 day of culture. We believe that our biomimetically-engineered platform in this study could increase the biomedical applications of fully bio-based systems such as scaffolding in tissue engineering.
