The influence of dimethyl sulphide and carbon disulphide in the bouquet of wines

Sensory evaluation of DMS added to wines at very low concentrations has shown that addition of 0.022 μl · l-1 resulted in statistically more favoured wines than those with no, or 0.044 μl · l-1 added DMS. This shows that low concentrations of DMS can have a beneficial effect on the quality of some wines.The concentration of CS2 necessary to give any sensory response was higher than that observed in any commercial wine.The threshold of smell for DMS in distilled water was found tobe 7.5 x 10-5 μl · l-1 (0.08 ppb) while that for taste was 4 x 10-4 μl · l-1 (0.4 ppb).Der Einfluß von Dimethylsulfid und Schwefelkohlenstoff auf das WeinaromaBei der sensorischen Beurteilung von Weinen, denen Dimethylsulfid in sehr niedrigen Konzentrationen zugesetzt worden war, wurden jene mit 0,022 μl · l-1 vor solchen ohne oder mit 0,044 μl · l-1 Dimethylsulfid bevorzugt. Geringe DMS-Mengen können demnach die Weinqualität positiv beeinflussen.Die sensorisch wahrnehmbare Schwefelkohlenstoffkonzentration war höher als die in den Weinen gefundenen Mengen.Der Geruchsschwellenwert für Dimethylsulfid in Aqua dest. betrug 7,5 x 10-5 μl · l-1, der Geschmacksschwellenwert dagegen 4 x 10-4 μl· l-1

A Case Base Approach for Evaluation of Manufacturing Effectiveness of a Firm Using Analytical Hierarchical Process

High level of Manufacturing Capability (MC) (effectiveness) plays significant role in providing competitive advantage to a firm. However, it is difficult for the firm to evaluate the level of MC, which is given by the consistency of decisions taken in the particular manufacturing environment. For example, in job shop production general purpose facilities and high skilled workforce is essential to obtain the desired level of outputs to satisfy customer expectations. First, Hayes and Wheelwright provided a four stage model for evaluating the level of MC and recently Miltenburg gave a framework that classified these four stages as infant, average, adult and world class. Evaluating MC facilitates the firm to know the present status and also provides a pointer to identify weak decisions for further improvement. This paper presents a case study on evaluating the MC of a firm involved in the production of low volume and high variety products. Job Shop Production System has been used to fulfill these demands. Objective of this research is to find out the current status (level) of MC of a firm based on the consistency of the decisions taken. For this, hierarchical model based on the overall goal as a MC index has been developed by using Analytical Hierarchical Process (AHP) a Multi Criteria Decision Making (MCDM) tool. The MC index of a firm under consideration is computed by evaluating the pattern of decisions taken in the manufacturing which are obtained after discussion with top executives of the company. The results obtained are then compared with ideally required decisions from the same category of manufacturing system (in this case job shop production system). Based on the comparison, status (level) of MC and weak decision areas of the firm have been identified and discussed with the executives

Study of association of non alcoholic fatty liver disease (NAFLD) with micro and macrovascular complications of type 2 diabetes mellitus (T2DM)

Background: Non Alcoholic Fatty Liver Disease (NAFLD) is a common liver disorder that is strongly associated with insulin resistance and Type 2 Diabetes Mellitus (T2DM). This study was designed to determine the prevalence of NAFLD among T2DM patients and to evaluate whether there is an association between NAFLD and diabetic micro-and macro vascular complications.Methods: In a cross-sectional design study, 120 type 2 diabetic patients were submitted to a complete clinical and laboratory evaluation and abdominal ultrasonography for NAFLD detection and grading. They were divided into fatty liver group and non-fatty liver group and various laboratory and clinical variables were compared in these two groups. Statistical analysis included bivariate tests, chi square test, univariate and multivariate logistic regression.Results: Out of 120 type 2 diabetic patients, 68 (56.66%) had fatty liver on ultrasonography. An increase in the waist circumference, BMI, systolic blood pressure, diastolic blood pressure and levels of HBA1c, AST, ALT, Total Cholesterol, Triglycerides and a decrease in HDL was observed in the fatty liver group as compared to non-fatty liver group. NAFLD group had higher prevalence of retinopathy (67.67% vs. 17.30%, P <0.001), neuropathy (52.94% vs. 19.23%, P = 0.0002), nephropathy (83.82% vs.53.84%, P = 0.0003). The prevalence of CAD (70.58% vs. 21.11%, P <0.0001) and POVD (10.25% vs. 0%, P <0.05) was higher in NAFLD patients. All patients with severe fibrosis had raised BMI, HbA1c and hypertension. The results of multiple logistic regression analysis showed that NAFLD was associated with BMI, HbA1c, Triglyceride and CAD. Univariate analysis showed significant association between retinopathy, neuropathy, CAD, POVD and NAFLD.Conclusion: Cognitive. The prevalence of NAFLD is higher in type 2 diabetic patients. Obesity, dysglycemia, dyslipidemia, elevated liver enzymes and coronary artery disease are seen to be significantly associated with fatty liver than non-fatty liver type 2 diabetic patients.

PAPR Reduction in OFDM System by using Nonlinear Companding Technique

Non linear companding technique is proposed to reduce the high peak to average power ratio (PAPR) of orthogonal frequency division multiplexing system. Use of companding for peak - to - average - power ratio (PAPR) control is explored for a link involving a non - linear transmit power amplifier with orthogonal frequency division multiplexing (OFDM). This paper analyses the improvement in bit error rate (BER) and overall system performance by employing non linear companding technique for PAPR reduction in digital video broadcasting (DVB - T) system

This article describes a case of 18year-old-female who presented with primary amenorrhea, phenotypic features of Turners syndrome, which was confirmed later by Karyotype to have mosaic 45XO(8)/46XY(22). She had delayed puberty and proved (hormonally) to have ovarian failure, with absent Mullerian structures (radiologically and laparoscopy)

MULTI-OBJECTIVE CHANNEL DECISION FOR ADHOC COGNITIVE RADIO NETWORK

Faithfull detection of non-utilized spectrum hole in available channel is a crucial issue for cognitive radio network. Choosing the best available channel for a secondary user transmission includes settling on decision of accessible choices of free frequency spectrum based on multiple objectives. Thus channel judgment can be demonstrated as several objective decision making (MODM) problem. An ultimate goal of this exploration is to define and execute a technique for multiple objective optimizations of multiple alternative of channel decision in Adhoc cognitive radio network. After a coarse review of an articles related to the multiple objective decision making within a process of channel selection, Multiple Objective Optimization on the basis of the Ratio Analysis (MOORA) technique is taken into consideration. Some important objectives values of non-utilized spectrum collected by a fusion center are proposed as objectives for consideration in the decision of alternatives. MOORA method is applied to a matrix of replies of each channel alternatives to channel objectives which results in set ratios. Among the set of obtained dimensionless ratios, all the channel alternatives are ranked in descending order. In MOORA, channel choices with moderate objectives can top in ranking order, which is hardly conceivable with linearly weighted objectives of the different channel by using different decision making technique
