Buccal mucosa has been used in both primary and salvage urethroplasties, as dorsal onlay. Ventral onlay, and as tubed grafts in posterior and anterior urethral strictures. It’s recommended as ideal graft material which offers many advantages: availability, easy and less infectious complications. Repeat urethroplasties were performed by excising the fibrous tissue around the stricture; buccal mucosa was then harvested from the inner cheek, made into graft tubing, and interposed into the defect. We report the results of our surgical experience with staged reoperation using BM, in the repair of post-traumatic membranous urethra stricture with loss of substance estimated to 5cm a patient of 22 years with complications after multiple failed repairs.

The knowledge of the structure of the boundary layer gives an idea to understand the capabilities of the atmosphere to dispose of pollutants. Finite difference technique with non-uniform grid is used to investigate the effect of various flow parameters on skin friction , heat transfer and other characteristics of two phase thermal boundary layer flow on a flat plate. Heat is diffused away from the heated surface for smaller values of Prandtl number Pr more rapidly than that of higher values of Pr. The particle density on the plate goes on increasing and attains a finite value of 3.5 at a far down stream station. The presence of coarser particles with high material density have an effect of increase in magnitude of particle velocity and particle phase density whereas to reduce the particle temperature. The increase in Prandtl number Pr is to increase the magnitude of carrier fluid velocity, particle velocity, particle phase density, coefficient of skin friction and Nusselt number where as to decrease the displacement thickness.

By more than a decade, the contemplation on the velocity law took me as far as the human mind could inform of, where I wondered at that time; what is the relationship between all of the time, space and velocity?. This question was frequented my imagination impotent, whenever I tried to understand the extent of the relation between these two numbers: zero and one. The following questions are the source of inspiration: At first glance, may not seem to us that there is a relation between these questions and the velocity law, but if we tried to conduct a scientific investigation on the velocity law during a theory of the high credibility, we are surprised how the trick that brought to us by classical physics. I firmly believe that the answer of these questions will strongly solve the biggest enigma in our live. Let's see how we will be able to get the Mared (giant) out of its bottle, through this research.

The recovery of significance topics and associated sources from environment where the information is readily available. In this project, fusion system has been developed to handle the information assembly method. Hierarchal Hyperbolic SOM (H2SOM) network is used in this system to configure the information background for information seeking process and to recover the information for the significant topic. Activation network has been used to choose the related information with reference to the existing knowledge. This network is used to choose the appropriate information from the source. This project use association rule of Data mining to examine the recognized topics. Association rule will perform numerical testing to examine the recognized topics. This system will be implemented in several industries and most applicable domain is hospital industry. Information overload has been monitored by this system. In this system information assembly method will be achieved effectively.

We prove that the upper domination number of a graph does not increase when a vertex is removed from the graph. Moreover, we consider well-dominated graphs and their upper domination number. We also define approximately well-dominated graphs.

Normally, humans have only one urinary bladder but it’s not so in the case of bladder duplication because more than one bladder is present in this case and it occurs as a result of an abnormal development of the body specifically the abnormal development of the urinary system during the fourth week of embryological development. Bladder duplication was classified by Abrahamson into two forms based on the degree of duplication; complete and incomplete bladder duplication. And also, it can be classified into sagittal or coronal duplication based on the position of the accessory bladder in relation to the normal bladder.

In this paper, we propose conventional and alternative ratio-product type estimators for population mean using two auxiliary variables in the presence of non-response. The purposed estimators have been found to be more efficient than the relevant estimators for the fixed values of first-phase sample of size n' and sub-sample of size n(<n') taken from the first-phase sample size n' under the specified condition. The purposed estimators are more efficient than the corresponding estimators for population mean (Y ?) of a study variable y in the case of fixed cost and have less cost in comparison to the cost incurred by the corresponding relevant estimators for a specified variance. The conditions under which the purposed estimators are more efficient then the relevant estimator have been obtained. An empirical as well as a Monte-Carlo simulation study have been done to demonstrate the efficiencies for the purposed estimators over other relevant estimators.

A Coumarin derivative, 4-ethoxy-6-((hydroxymethoxy)methyl)-2H-chromen-2-one, was isolated from the stem bark of Jatropha multifida, and its structure was elucidated from UV, IR, MS and 2D NMR spectra. The compound has 1-oxygenated structure with a lactone moiety.

Given an arbitrary finite group , denote by the set of its element orders. The group is said to be recognizable by the set if the equality implies an isomorphism of and for each finite group . For a prime , the alternating groups are recognizable. But for are has not known. In this paper, we will give an example for not a prime, namely, that is characterizable.

In this paper, we study some of the properties of Q-fuzzy normal subgroups, cosets and prove some results on these.
