Let V be a non empty zero structure. An element of Cthe carrier of V is said to be a C-linear combination of V if: (Def. 1) There exists a finite subset T of V such that for every element v of V such that v / ∈ T holds it(v) = 0. Let V be a non empty additive loop structure and let L be an element of Cthe carrier of V . The support of L yielding a subset of V is defined by: (Def. 2) The support...

Received October 6, 1992; revised manuscript received October 4, 1993; permission to publish received July 6, 1994 A novel approach involving a delay-trigger method and doped, glassy polymers has been developed to determine the contribution of the electric-field-induced third-order effect to the second-order macroscopic susceptibility x(2) of nonlinear optical dyes. A submillisecond, variable t...

There is a large amount of enrichment rare earth elements in Zhungeer coal and ash, making it possible to use fly ash as source for industrial production elements. In order optimize the leaching process increase rate, circulating fluidized bed Power Plant was used material, single factor test orthogonal were influence rate acid The factors discussed, results showed that when 3mol/L hydrochloric...

Title of Document: PHYSICAL PROPERTIES OF LAMPREY SPINAL CORD REGENERATION: ADAPTIVE VS. MALADAPTIVE RECOVERY Carlos Luna Lopez, Ph. D., 2014 Directed By: Associate Professor, Helim Aranda-Espinoza, Fischell Department of Bioengineering Spinal cord injury (SCI) is a physical trauma that can result in paralysis and even death; to date no treatment exists that can successfully promote functional ...

Dissimilar metals friction welding of austenitic–martensitic stainless steels is commonly used in order to manufacture engine valves in the automobile industry. In this study, X53CrMnNiN219 (austenitic stainless steel) and X45CrSi93 (martensitic stainless steel) valve steel rods were welded by friction welding process. The welded joint was then heat treated at 760 0C for 60 min. Mechanical prop...

This study examines the fatigue and anisotropy behaviour of cold rolled AA1200 aluminium alloy for light weight automotive connecting rod application. Aluminium (Al) 1200 ingots were melted at temperature of 680 0C (after one hour of heating) cast in sand mould and cast samples homogenized for 6 hrs at 480 0C. The cold rolling process was carried out after homogenisation for 10, 20, 30, 40 and ...

Endothermy in insects is normally associated with flight but has been observed during strictly terrestrial activity in beetles (Bartholomew & Casey 1977a, b). A study by Bartholomew & Heinrich (1978) in Kenya showed that dung beetles are conspicuously endothermic during flight, ball making and ball rolling, and sometimes while walking. Endothermy during terrestrial activity is probably advantag...

Problem statement. A feature of the modern technical systems’ design is that deterministic approaches dominate, while consideration uncertainty can provide a more adequate representation research object in appropriate calculation scheme, mathematical model. The uncertainties becomes especially relevant modeling complex systems, where be quite abundant and themselves different nature, namely sto...
