Ionomers are generally described by copolymers having either acrylic or methacylic acid as one component and the other component is mostly either ethylene or styrene. The objective of this research was to study the thermal behaviour and stability of ionomers of styrene with some alkali metal acrylates. These materials have been synthesized by neutralization of the respective copoly...

We study the long run effects of one of the most ambitious place based economic development policies in U.S. history: the Tennessee Valley Authority (TVA). Using a rich panel dataset of counties, we conduct an evaluation of the dynamic effects of the TVA on local economies in the seventy years following the program’s inception. We find that the TVA led to short run gains in agricultural employm...

Individuals with developmental dyslexia usually exhibit a problem in simultaneous processing of multiple visual elements. However, the relationship between impaired (VSP) and reading difficulty is still debated. These inconsistencies may be associated wide range participants’ age, variation orthographic depth background languages, complex subcomponents underlying VSP. The present study thus exa...

Laser-Induced Thermionic Vacuum Arc (LTVA) provides a better way to produce uniform metallic thin films than the classical (TVA) method. In Ti-doped chromium produced using LTVA, amorphous is superimposed with small bcc nanoparticles. These amorphous/crystalline structures crystallites induce lower roughness and electrical resistivity, reducing electron–phonon scattering increasing charge trans...

A key issue in cancer biology is whether genetic lesions involved in tumor initiation or progression are required for tumor maintenance. This question can be addressed with mouse models that conditionally express oncogenic transgenes, i.e., under the control of tetracycline (tet)-dependent transcriptional regulators. We have developed a system for studying tumor maintenance by using avian retro...

Les effets d’une hausse de la TVA sur le niveau vie et les inegalites sont a fois directs differes. Une telle se traduit l’annee meme par une augmentation des prix. Dans un second temps, revenus d’activite autres types s’ajustent partiellement. Par ailleurs, baremes prestations sociales impots indexes l’inflation. Ces travaux proposent evaluation ex ante ces mecanismes via modele microsimulatio...

Background: Oral submucous fibrosis (OSMF), now worldwide acknowledged as the disease of “Southeast Asia and Indian subcontinent”, has utmost malignant transformation prevalence amongst oral precancerous disorders. Increased vascularity that is neoangiogenesis been observed in superficial connective tissue region pre-cancerous lesions showing dysplasia. This could be...

Tumors develop through multiple stages, implicating multiple effectors, but the tools to assess how candidate genes contribute to stepwise tumor progression have been limited. We have developed a novel system in which progression of phenotypes in a mouse model of pancreatic islet cell tumorigenesis can be used to measure the effects of genes introduced by cell-type-specific infection with retro...

The association of Tricuspid Regurgitation (TR) to left side heart valve diseases is common but surgical indications during left side heart surgery is still controversial and tricuspid valve annuloplasty (TVA) ranging from more than 60% to 6% depending on each single institution strategy. This study aims to evaluate clinical and instrumental results of adjunctive TVA during left side heart valv...
