Sentences with phrase «studying phase contrast»

Most other groups studying phase contrast X-ray imaging are looking into the technique for medical imaging, while Sandia is studying it for materials science applications.

Not exact matches

Holographic, phase contrast or differential interference contrast (DIC) miscroscopes have been implemented especially for making «visible,» otherwise «invisible,» transparent objects, opening a new pathway towards the study and characterization of relevant structures such as biological cells or protein layers.

«Studying the formation and evolution of jets in metals and, more generally, how materials at extreme conditions respond using X-ray phase contrast imaging is relevant to such things as meteorite impacts, the performance of explosives and detonators, understanding crack nucleation and propagation in materials, and the development of new materials with tailored properties whose applications include automotive and airplane components, lighter and more impact - resistant armor, and debris shields in space, to name a few.»

X-ray phase contrast imaging could be used to inspect microfabrication packaging, integrated circuits or micro-electro-mechanical components and could be used to study ceramics, polymers, chemicals or explosives.

So Sandia borrowed and refined a technique being studied by the medical field, X-ray phase contrast imaging, to look inside the softer side of things without taking them apart.

Adhering to these traditional concepts the US Department of Agriculture has concluded that diets, which reduce calories, will result in effective weight loss independent of the macronutrient composition, which is considered less important, even irrelevant.14 In contrast with these views, the majority of ad - libitum studies demonstrate that subjects who follow a low - carbohydrate diet lose more weight during the first 3 — 6 months compared with those who follow balanced diets.15, 16, 17 One hypothesis is that the use of energy from proteins in VLCKD is an «expensive» process for the body and so can lead to a «waste of calories», and therefore increased weight loss compared with other «less - expensive» diets.13, 18, 19 The average human body requires 60 — 65 g of glucose per day, and during the first phase of a diet very low in carbohydrates this is partially (16 %) obtained from glycerol, with the major part derived via gluconeogenesis from proteins of either dietary or tissue origin.12 The energy cost of gluconeogenesis has been confirmed in several studies7 and it has been calculated at ∼ 400 — 600 Kcal / day (due to both endogenous and food source proteins.18 Despite this, there is no direct experimental evidence to support this intriguing hypothesis; on the contrary, a recent study reported that there were no changes in resting energy expenditure after a VLCKD.20 A simpler, perhaps more likely, explanation for improved weight loss is a possible appetite - suppressant action of ketosis.
