We use a deformed quasiparticle random phase approximation formalism to describe simultaneously the energy distributions of the single b Gamow-Teller strength and the two-neutrino double b decay matrix elements. Calculations are performed in a series of double b decay partners with A=48, 76, 82, 96, 100, 116, 128, 130, 136, and 150, using deformed Woods-Saxon potentials and deformed Skyrme Hart...

The objective of this study was to compare the flexural strength and elasticity modulus of two types of staple reinforcement fibers, Interlig - Angelus/glass (Londrina, PR, Brazil) and Connect - KerrLab(R)/polyethylene (MFG Co., West Collins Orange, CA, USA), which are widely used in Dentistry for chairside use, after varying the number of layers employed and submitting or not to thermocycling....

BACKGROUND Bond strength of adhesive layer can absorb unwanted stresses of polymerization shrinkage in composite resin restorations; increased microshear bond strength can prevent failure of restoration materials, the purpose of this study was to evaluate the effect of adhesive layers on microshear bond strength of nanocomposite resin to dentin. MATERIAL AND METHODS Two different types of adh...

A systematic study on the effect of electrostatic double layer interaction on permeate flux decline and deposit cake formation in crossflow membrane filtration of colloidal suspensions is reported. Three monodisperse silica suspensions with diameters of 47, 110, and 310 nm were used as model colloids, and a tubular zirconia membrane with an average pore diameter of 20 nm was used as a model mem...

Experimental results are presented on the effect of coupling on synchronization of two coupled nonidentical Chua’s oscillators. Two oscillators are coupled in unidirectional drive response mode. The driver is always kept in chaotic ~single scroll, double scroll! state while the response oscillator is kept in various dynamical states as point attractor, single scroll periodic, chaotic and double...

let  be a banach algebra. let  be linear mappings on . first we demonstrate a theorem concerning the continuity of double derivations; especially that all of -double derivations are continuous on semi-simple banach algebras, in certain case. afterwards we define a new vocabulary called “-higher double derivation” and present a relation between this subject and derivations and finally give some ...

The effects of lower bainite volume fraction on tensile and impact properties of D6AC ultrahigh strength steel were studied in the current work. To obtain mixed microstructures containing martensite and different volume fractions of the lower bainite, specimens were austenitized at 910° C, then quenched in a salt bath of 330°C for different holding times, finally quenched in oil. In order to ob...

Manipulating structure, defects and composition of a material at the atomic scale for enhancing its physical or mechanical properties is referred to as nanostructuring. Here, by combining advanced microscopy techniques, we unveil how formation of highly regular nano-arrays of nanoparticles doubles the strength of an Fe-based alloy, doped with Ti, Mo, and V, from 500 MPa to 1 GPa, upon prolonged...

در پایان نامه حاضر با در نظر گرفتن واکنش 238u+16o، پتانسیل برهمکنش بین دو یون سنگین کروی و تغییر شکل یافته با استفاده از مدل double-folding محاسبه شده است. در محاسبه پتانسیل double-folding از برهمکنش نوکلئون-نوکلئون m3y از نوع paris استفاده شده است. وابستگی پتانسیل برهمکنش ، سطح مقطع همجوشی و توزیع سد همجوشی به شکل و جهت گیری های مختلف هسته هدف بررسی شده است. برای تطابق بهتر با داده های تجربی ،...
