Al assisted alloying of carbon steel in Submerged Arc Welding (SAW) by Al-Cr-Ti-Cu unconstrained metal powders is applied. A base case without powder additions compared to two addition schedules, Al-Cu-Ti and Al-Cu-Ti-Cr. used as a deoxidiser element control the oxygen partial pressure at weld pool–molten flux interface ensure that most Ti Cr transferred into pool ppm O controlled within accept...

A simple dilute-and-shoot procedure for determination of Cr, Ni, Pb and V in ethanol fuel by Microwave Plasma-Atomic Emission Spectrometry (MP-AES) is proposed. Samples were easily prepared and neither special nor expensive gases were needed for performing analyses. All limits of detection from 0.3–40 μg/L were compatible with the requirements taken into account when considering fuel impacts on...

In use of saturable Cr(4+):YAG crystals, we have demonstrated the stable Q-switched and mode-locked (QML) operation of the Nd:LuVO(4) laser. The operation range of QML in use of the Cr(4+):YAG is larger than that use of SESAM and NLM. The obtained shape of Q-switched envelope, repetition rate and pulse energy are demonstrated to depend on the initial transmittance of the Cr(4+):YAG and reflecti...

We evaluated the effects of diet on intestinal tumorigenesis in male Apc(Min) mice by comparing AIN-76A diet fed ad libitum (CON); calorie intake restricted by 40% of the CON (CR); diet high in olive oil and supplemented with freeze-dried fruit and vegetable extracts (OFV); and diet high in total fat (HF). Compared with CON, the frequency of intestinal polyps was reduced by 57% by CR (P < 0.001...

Growth hormone receptor/binding protein knockout (GHR-KO) mice live approximately 40% longer than their normal siblings do. These mice have dramatically reduced plasma levels of insulin-like growth factor 1 (IGF1) and enhanced insulin sensitivity. We examined the expression level of peroxisome proliferator-activated receptors (PPARs) and retinoid X receptors family genes in the livers of normal...

This work demonstrates that intraventricular microinjections of a low dose of potassium dichromate (0.4 microL of 10 mM solution) yield a specific contrast enhancement of white matter (WM) tracts in T1-weighted 3D MRI of mouse brain in vivo. Pronounced and persistent signal increases (40-100% at 24 hr after injection) were observed in the corpus callosum, anterior commissure, fornix, and stria ...

Introduction: At 7T in the human brain reduced RF amplitude and increased spectral dispersion result in chemical shift dispersion (CSD) artifacts that can distort metabolite ratios. For 2D encoding within the plane of a slice, CSD artifacts can be eliminated by replacing in-plane gradient based slab selective refocusing with RF shimming based outer volume suppression. However, for 3D acquisitio...

Depressurization is the dominant process that produces mantle melts on Earth. Depressurization had equally profound but quite different effects in the evolution of ureilite meteorites. The second most abundant type of achondrite, ureilites formed as anatectic restites (olivine + pyroxene + minor, 0.2-6 wt%, carbon) in the mantle(s) of carbonaceous asteroid(s). In ureilites, de-pressurization wa...

Background and Objectives: Calorie restriction (CR) is one of the proven methods of extending lifespan and slowing aging. Leptin is a nutritionally regulated adipokine that has been proposed as a possible key signal in the adaptive responses relevant to CR. Under CR, plasma leptin levels decrease, thus it was hypothesized that leptin administration may counteract CR-induced weight loss. Therefo...

Cardiac rehabilitation (CR) programs first appeared in the United States in the late 1960s. Over the past 40 years, CR has evolved into a comprehensive rehabilitation and secondary prevention service, delivered by a multidisciplinary staff, and based on scientific and clinical evidence. CR is now recognized as an important element in the continuum of care for patients with cardiovascular diseas...
