The viscoelastic behavior of bucky paper reinforced epoxy laminar composite materials for structural application has been evaluated through Dynamic Mechanical Analysis. The effects of heating rate, sinusoidal forces on glass transition temperature Tgwere studied. In DMA LVDT controlled sinusoidal force is applied and measures the response of the input as shown in the figure 3. It measures parameters which are the signature properties of the material under supervision like storage modulus, loss…

Type IV pili are a family of appendage protein filaments that are assembled on the surfaces of many different microorganisms, such as bacteria and archea. The wide range of diverse microorganisms within the type IV pili family indicates that there must be both a common evolutionary origin, as well as a versatile functionality (Giltner, Nguyen and Burrows 2012). The formation of type IV pili occurs when the enzyme PilD, first recognized in the bacterial species Pseudomonas aeruginosa, catalyzes…

on these molecules throughout the initial phase of T cell activation. CD8+ T cells are cytotoxic T cells; they recognize peptides represented on MHC Class I. MHC Class I is located on all nucleated cells. T cells with CRTAM (CRTAM+) mediate cell adhesion with its ligand, Cadm1. CD8+ T cells with CRTAM associate with CD8+ dendritic cells with Cadm1 in lymph nodes. This association is crucial for the aggregation of antigen-specific cytotoxic T cells (CTLs) and their consequent increase when…

The intention of this systematic review of literature is to evaluate the validity of chiropractic as a specific tool in the management of infertility. The challenge in all of this is not only to understand the role of vertebral subluxation on fertility but to understand infertility as a whole. Epidemiology Infertility is defined as the failure to reproduce after twelve months of unprotected sexual intercourse. It is estimated that between 50 and 80 million couples of childbearing age are…

Chapter Two Literature Review 2.1 Multiple Sclerosis Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system (CNS) that remains incurable. The disease manifests as a wide range of neurological deficits including cognitive impairment, impaired coordination, visual disturbances, and extremity numbness (Weinshenker et al., 1989). MS affects approximately 400,000 people in the US and 2.5 million worldwide and it is the most common inflammatory neurological disease…

ABSTRACT Diabetic retinopathy (DR) remains a major complication of diabetes and the leading cause of blindness among adults worldwide. DR is a progressive disease affecting both type I and type II diabetic patients at any stage of the disease, and targets the macrovascular and microvascular systems of the retina. DR results from multiple biochemical, molecular and pathophysiological changes to the retinal vasculature which affect both microcirculatory functions and ultimately photoreceptor…

a localized increase in tumor size and induction of angiogenesis to support the tumor growth. This is followed by detachment of cells from the site. Detachment is facilitated by cytoskeletal remodeling and breakage of cell-cell and cell-stroma adhesions; cells migration begins towards the basement membrane. The disruption of the basement membrane is initiated by active secretion of proteolytic enzymes (matrix metalloproteinase); cells enter the systemic circulation through bloodstream or…

agreement was for the dates March 1, 2001 – February 28, 2002. INDOT’s solicitation to bidders was, all bidders are required to be familiar with testing glass beads to the ASHTO M 247 standard. The glass beads were to have moisture resistant and adhesion coating(s) and be in accordance…

A garage floor coating increases the useful life of the floor's concrete. All too often, these floors become stained and suffer from salt induced damage such as cracking, flaking, and spalling. Whether or not you enjoy this benefit will depend on getting the details of its application right. Here are six mistakes that the best garage floor coating professionals never make: Not Checking for Moisture Problems Like a sponge, concrete has pores through which moisture penetrates. If the ground…
