Action and Function of Neutrophils in Crohn`s Disease
The precise mechanisms underlying the development of Crohn’s disease (CD) remain controversial, but sufficient data have been collected to suggest that an uncontrolled immune response within the intestinal mucosa leads to inflammation in a genetically susceptible host. Although lack of mucosal regulatory T cells causes colitis in humans and experimental rodents, patients with CD have more rather than less regulatory activity in the intestine, apparently excluding defects in tolerance as the cause of CD. Genome‐wide association studies have identified many gene variants that confer susceptibility and which seem associated to diminished functioning of especially innate immunity. In apparent agreement, CD patients are impaired with respect
Reliability Estimation Model for Software Components Using CEP
This paper presents a graphical complexity measure based approach with an illustration for estimating the reliability of software component. This paper also elucidates how the graph-theory concepts are applied in the field of software programming. The control graphs of several actual software components are described and the correlation between intuitive complexity and the graph-theoretic complexity are illustrated. Several properties of the graph theoretic complexity are presented which shows that the software component complexity depends only on the decision structure. A symbolic reliability model for component based software systems from the execution path of software components connected in series, parallel or mixed configuration network structure is presented with a crisp narration of the factors which influence computation of the overall reliability of component based software systems. In this paper, reliability estimation model for software components using Component Execution Paths (CEP) based on graph theory is elucidated
A probabilistic approach for modelling the joint action of drugs
An understanding of the joint action of drugs is
becoming increasingly important in a variety of scientific
disciplines, ranging from pharmacology and toxicology on the
one hand to industrial hygiene and environmental protection on
the other. The action of even a single drug upon a biological
organism involves a complex sequence of processes and if
more than one drug is present, the situation is further complicated
The role of mathematical models in this context is
now widely recognized (Plackett & Hewlett 1952, Hewlett and
Plackett, 1959, 1979, Ashford and Cobby 1974, Ashford 7981
ECOFRIENDLY NUTRIENT MANAGEMENT PRACTICES FOR YIELD AND QUALITY OF BANANA
Banana owing to its large size and rapid growth rate require relatively large amount of nutrients for higher yield of quality fruits and it is estimated that 50 tonnes of banana in one hectare removes 320kg N, 32kg P2O5 and 925 kg K2O every year (Lahav and Turner, 1983). Application of inorganic fertilizers though increases the yield substantially but could not able to sustain the fertility status of the soil (Bharadwaj and Omanwar, 1994) and have caused several undesirable consequences in the fragile soil eco-system, leading to gradual decline in productivity. Considering the present situation of soil quality and environmental security, it is necessary to go for an integrated nutrient management, involving various sources of organic manures, organic cakes and bio-fertilizers besides using chemical fertilizers in banana. In today’s cultivation many commercial organic manures are being used because of their application in lesser volume and also enriched with nutrients. One such commercial organic manure used in the study is Wellgro. Wellgro organic manure is a unique product with a blend of neem and non-timber forest produce and a rich source of nutrients. Hence, this study was under taken to find out the influence of ecofriendly nutrient management practices on yield and quality parameters of banana under irrigated conditions
Pair difference cordial labeling of some union of graphs
Let G = (V, E) be a (p, q) graph. Define ρ = {p/2 if p is even p−1/2 if p is odd and L = {±1, ±2, ±3, · · · , ±ρ} called the set of labels. Consider a mapping f : V → L by assigning different labels in L to the different elements of V when p is even and different labels in L to p-1 elements of V and repeating a label for the remaining one vertex when p is odd. The labeling as defined above is said to be a pair difference cordial labeling if for each edge uv of G there exists a labeling |f(u) − f(v)| such that ∆f1 − ∆fc1 ≤ 1, where ∆f1 and ∆fc1respectively denote the number of edges labeled with 1 and number of edges not labeled with 1. A graph G for which there exists a pair difference cordial labeling is called a pair difference cordial graph. In this paper we investigate the pair difference cordial labeling behavior of the union of some graphs like path, cycle, star and bistar graph.Publisher's Versio
