Primary infection of the larynx with aspergillus spp. with immunocompetent patient is extremely rare, few cases have been reported in the literature. It is more commonly seen as a part of a wider infection involving the respiratory system in immunocompromised patients. We present one case of primary laryngeal aspergillosis without any other airway tract extension and without any generalized immune deficit in a 69 year-old woman with history of hoarseness. Direct laryngoscopy and biopsy confirmed the diagnosis of aspergillosis.

A congenital coronary artery fistula is an uncommon anomaly which has a direct communication between a coronary artery and the lumen of any one of the four cardiac chambers, or the coronary sinus, or its tributary veins or the superior vena cava. The right coronary artery is involved most frequently, and the abnormal communication in most often is to the right ventricle followed in incidence by drainage into the right atrium and the pulmonary artery. Recently. we experienced a case of congenital coronary artery fistula associated with valvular heart disease. The fistulous communication was noted between the left circumflex artery and the left atrial appendage. Under the cardiopulmonary bypass, the internal obliteration of the left atrial appendage, mitral valve replacement, and aortic valve exploration were accomplished. Postoperative hospital course was uneventful and the patient was discharged without any problems.

In the modern ages when the surroundings of a city has become firm and monotonous this study designed to suggest an direction towards creative approaches to space planning by analyzing the images of interior space with the introduction of natural expressions as an alternative to create original space in order to give vitality to the previous standardized space and to satisfy human beings psychological desire. The results of the analysis as a way of expressing direct indirect and eclectic images using nature a source of arts read that most of the natural expressions show perceptive images strongly that natural elements can become the elements of design in any form and that nature's images are expressed by not only natural and artificial materials. In conclusion natural expression in interior space does not have any fixed form of expression but gives a great deal of vocabulary to the image formation of interior space by stimulating being's sentiment with the spatial restructure of nature's own particular order of form.

This paper presents a virtual machine design simulation program. Kinematics of various mechanisms can be modeled with 3 dimensional geometry and actuators. CAD data for any machine component can be easily imported in STL format. Machine components are assembled with kinematic joints simply by drag and drop function in virtual graphic simulator. Interference and collision of any component with other components can be identified during the motion simulation. Graphic user interface program is developed using Microsoft Direct X code. A precision micro stage system is demonstrated with the proposed virtual machine design simulator.

Colony blot hybridization using a VVHP DNA probe derived from the sequence of the hemolysin gene, vvhA, was specific in identifying all V. vulnificus strains, thereby, eliminating the need for any additional phenotypic identification. The colony blot hybridization procedure revealed a sensitivity and broad applicability sufficient for the direct enumeration of V. vulnificus in various natural samples, without the use of enrichment or culturing on selective medis. V. vulnificus was detected in all natural samples collected during August and May at concentrations ranging from $2.1{\times}10^1\;to\;4.0{\times}10^3$ organisms per ml. However, during November and February, when the mean temperatures of the seawater were $12^{\circ}C$ and $5^{\circ}C$, respectively, V. vulnificus was not detected in any natural samples.

Variable weld bead penetrations related to the base metal chemistry of stainless steels in GTA welding have been under constant investigations due to their industrial implications. It has been proposed that among other elements, the sulfur content of steels determines the weld pool geometry, particularly its penetration. It is suggested that the surface tension temperature gradient of steels becomes positive with appropriate dosing in sulfur and results in inward melt flow, propitious for deeper welds. However, the chemistry of industrial steels is complex due to the presence of multiple minor elements either deliberately added or remnant impurity traces. With this in view, investigations on 41 austenitic and nine martensitic stainless steels were carried to see if there existed any possible relation between the weld profile and some of the designated elements. The results suggest no direct correlation between sulfur or any other major or trace element and weld penetration. At first glance the results are contradictory to what is often asserted.

Structural uncertainties are generally modeled using probabilistic approaches in order to quantify uncertainties in behaviors of structures. This uncertainty results from the uncertainties of structural parameters. Monte Carlo methods have been usually carried out for analyses of uncertainty problems where no analytical expression is available for the forward relationship between data and model parameters. In such cases any direct mathematical treatment is impossible, however the forward relation materializes itself as an algorithm allowing data to be calculated for any given model. This study addresses a new method which is utilized as a basis for the uncertainty estimates of structural responses. It applies double uniform random numbers (i.e. DURN technique) to conventional Monte Carlo algorithm. In DURN method, the scenarios of uncertainties are sequentially selected and executed in its simulation. Numerical examples demonstrate the beneficial effect that the technique can increase uncertainty degree of structural properties with maintaining structural stability and safety up to the limit point of a breakdown of structural systems.

The following statements for an infra-Krull domain $R$ are shown to be equivalent: (1) $R$ is a Krull domain; (2) for any essentially finite $w$-module $M$ over $R$, the torsion submodule $t(M)$ of $M$ is a direct summand of $M$; (3) for any essentially finite $w$-module $M$ over $R$, $t(M){\cap}pM=pt(M)$, for all maximal $w$-ideal $p$ of $R$; (4) $R$ satisfies the $w$-radical formula; (5) the $R$-module $R{\oplus}R$ satisfies the $w$-radical formula.

The actions of Atractylodes rhizoma alba on renal function of dog were investigated with water and methanol extract of it, utilizing clearance technique. Water extract elicited diuresis while methanol extract induced antidiuresis in the dog when they were given intravenously. The diuresis induced by the intravenous water extract seemed to be closely related to the decrement of reabsorption of electrolytes in renal tubules. On the contrary, the antidiuresis by intravenous methanol extract appeared to be related to the increment of renal reabsorption of sodium. Water and methanol extract, when infused into a renal artery, exhibited identical resposes to the intravenous actions confined only to the infused kidney, inferring that renal actions of water and methanol extract are not mediated by any endognous humoral extract are not mediated by any endogenous humoral agents. From these observations it is concluded that diuretic action of water extract and antidiuretic action of methanol extract were brought about by direct action in the renal tubules.

Cotton fabrics were treated by low temperature plasma and/or cellulase, and its physical and dyeing properties were investigated. All the pretreatments of the cotton with low temperature plasma of oxygen, nitrogen and argon slowed down the rate of weight loss of cotton in cellulase solution. Plasma pretreatment did not show any strength retention effect on cotton fiber in the subsequent cellulase treatment. Pretreatment of cotton with low temperature oxygen plasma decreased the rate of dyeing in direct dye bath, while cellulase or plasma/cellulase pretreatment increased the rate. Equilibrium dye uptake of cotton was not changed greatly by the pretreatments except the normal untreated cotton showed more or less high uptake. The pretreatment of cellulase with a water-soluble carbodiimide reduced the enzymatic activity, and did not show any strength retention of cotton in enzymatic weight loss.
