    Full Text Available Aromatic precursors are precisely in the skin of grapes and nearby cells, and therefore there is a greater expression of the varietal aromas and aromatic precursors when the wine passes through this skin contact, as well as changes in product color. The aim of this study was to evaluate the physical and chemical characteristics of Chardonnay wine that has gone through different periods of skin contact. Chardonnay grapes, grown in vineyards located in the town of Bagé, in Campanha Gaúcha, were de-stemmed, crushed and a sulfur dioxide (50 mg/L−1 was addeded. The experimental design was a 4 × 3 factorial of 4 treatments with 3 repetitions: T1, the wine obtained directly from pressing machine; T2, skin contact for 2 days; T3, skin contact for 4 days and T4, skin contact for 6 days. After the end of malolactic fermentation wines went under − 2∘C for the tartaric stabilization. There were analyzed the variables alcohol, total acidity, volatile acidity, total polyphenols, glycerol, gluconic acid and 420, 520 and 620 colors by infrared spectroscopy method by Fourier transform and the means were compared by 5% Tukey test. There was a significant differencein variables alcohol, volatile acidit, glucanic acid and color index of 420 nm (yellow.

    2015-11-01

    This paper refers to the description of the way in which can be presented to future marine engineers the analyzis of the performance of an Otto cycle, in a manner which is beyond the classic approach of the course of thermodynamics in Constanta Maritime University. The conventional course of thermodynamics is dealing with the topic of performance analysis of the cycle of the internal combustion engine with isochoric combustion for the situation in which the working medium is treated as such a perfect gas. This type of approach is viable only when are considered relatively small temperature differences. But this is the situation when specific heats are seen as constant. Instead, the practical experience has shown that small temperature differences are not viable, resulting the need for variable specific heat evaluation. The presentation bellow is available for the adiabatic exponent written as a liniar function depending on temperature. In the section of this paper dedicated to methods and materials, the situation in which the specific heat is taken as constant is not neglected, additionaly being given the algorithm for variable specific heat.For the both cases it is given the way in which it is assessed the work output. The calculus is based on the cycle shown in temperature- entropy diagram, in which are also indicated the irreversible adiabatic compression and expansion. The experience achieved after understanding this theory will allow to future professionals to deal successfully with the design practice of internal combustion engines.

    Diamond detectors are used as beam loss and luminos- ity monitors for CMS and LHC. A time resolution in the nanosecond range allows to detect beam losses and lumi- nosities of single bunches. The radiation hardness and neg- ligible temperature dependence allow the usage of diamond sensors in high radiation fields without cooling. Two differ- ent diamond detector types are installed at LHC and CMS. One is based on pcCVD (polycrystalline chemical vapor deposition) diamonds and installed at different locations in the LHC tunnel for beam loss monitoring. Measurements of these detectors are used to perform a bunch-by-bunch beam loss analysis. They allow to disentangle the origin of beam losses. The second type uses scCVD (single crystal chemical vapor deposition) diamonds and is located inside CMS for van-der-Meer scan, beam halo and online lumi- nosity monitoring and around the LHC tunnel for beam loss observation. Results on the performance of these detectors will be presented and examples of the use for analyzi...

    Full Text Available Purpose: The main purpose of this study was to compare the phenomenon of interfrm cooperation strategy in both hyper-growth, and stable-growth knowledge and technology–intensive frms, in a country characterized by a high level of generalized trust: Sweden. Methodology: Qualitative methods were incorporated: direct semistructured interviews with top managers in 13 ICT frms (8 hyper-growth and 5 stable-growth, analyzis of reports, corporate websites and press releases. Furthermore, interviews in 3 expert frms in the industry were conducted, facilitating interfrm cooperation. Conclusions: There were signifcant differences in interfrm cooperation strategy in two distinguished groups of the frms: hyper-growth, and stable-growth. Managers’ individual approaches to uncertainty, strategy and cooperation might be more important than institutional settings. The ICT frms operate in a constantly changing global environment and local context seems to have only a minor impact on the rules of the game in the industry. Research limitations: This study was a qualitative explorative approach as an introduction to further empirical research. Originality: The study presents an interfrm cooperation phenomenon incorporating different perspectives and settings. It contributes to alliance portfolio literature (forming and managing of alliance portfolio in a different context/country/industry, and enhances understanding of frm strategies characterized by different growth rates.

  3. ClusTrack: feature extraction and similarity measures for clustering of genome-wide data sets.

    Directory of Open Access Journals (Sweden)

    Halfdan Rydbeck

    Full Text Available Clustering is a popular technique for explorative analysis of data, as it can reveal subgroupings and similarities between data in an unsupervised manner. While clustering is routinely applied to gene expression data, there is a lack of appropriate general methodology for clustering of sequence-level genomic and epigenomic data, e.g. ChIP-based data. We here introduce a general methodology for clustering data sets of coordinates relative to a genome assembly, i.e. genomic tracks. By defining appropriate feature extraction approaches and similarity measures, we allow biologically meaningful clustering to be performed for genomic tracks using standard clustering algorithms. An implementation of the methodology is provided through a tool, ClusTrack, which allows fine-tuned clustering analyses to be specified through a web-based interface. We apply our methods to the clustering of occupancy of the H3K4me1 histone modification in samples from a range of different cell types. The majority of samples form meaningful subclusters, confirming that the definitions of features and similarity capture biological, rather than technical, variation between the genomic tracks. Input data and results are available, and can be reproduced, through a Galaxy Pages document at http://hyperbrowser.uio.no/hb/u/hb-superuser/p/clustrack. The clustering functionality is available as a Galaxy tool, under the menu option "Specialized analyzis of tracks", and the submenu option "Cluster tracks based on genome level similarity", at the Genomic HyperBrowser server: http://hyperbrowser.uio.no/hb/.

    Full Text Available Curcuma mangga, Val. has been recognized as a traditional drug since a long time ago. The active ingrediences of this plant especially the volatile oil contains monoterpenes and sesquiterpenes. This research was aimed to study about the larvacide’s activity of the volatile oil Curcuma mangga, Val. rhizome and also to analyze its chemical compounds using the GC-MS. The volatile oil was isolated from Curcuma mangga, Val. with steam and water distillation. The test method for larvicide was done by dissolving the substances into water and added by Tween 20 10% v/v to the the volatile oil. The concentration of the volatile oil of Curcuma mangga, Val. rhizome were 100 ppm, 150 ppm, 200 ppm, 250 ppm, 300 ppm, and 350 ppm. The concentration of positive control “abate” were 0,01 ppm; 0,025 ppm; 0,05 ppm; 0,1 ppm; 0,5 ppm while as the negative control was Tween 20 solution. The perception time of larvae’s mortality was 24 hours. The chemical compound of Curcuma mangga, Val. can be analysed by the GC-MS. Data of larvae’s mortality were used to estimate the values of LC50 with the probit analyzis method. This study showed that the volatile oil of Curcuma mangga, Val. have clear-brass colour, bitter taste, typically aromatic like mango, rendement equal to (1,23 ± 0,029% v/b and refractive index 1,4881. The value of LC50 for the volatile oil of Curcuma mangga, Val. rhizome is (216,17 ±12,51 ppm while abate equal to (0,072 ± 0,024 ppm. This finding indicates that abate were more potent to larvae of Aedes aegypti. The GC-MS showes 30 peaks chromatogram and six peaks which indicates the possibility of alpha-pinene, camphene, beta-pinene, beta-myrcene, eukalyptole, ar-turmerone presence.

    The {pi}{sup -}p interactions with at least one charged secondary produced at polar angle {approx equal} 90deg in c.m.s. and having the transverse momentum above 1 GeV/c were investigated. The data were obtained using streamer chamber magnetic spectrometer RISK at 38 GeV/c {pi}{sup -} beam from Serpukhov accelerator. The analyzis of associated production in reconstructed events suggests, that if the transverse momentum of a pair of oppositely charged secondaries compensates the trigger particle p{sub perpendicular} {sub to} practically completely, this pair is the product of the {rho}{sup 0}-meson decay in marked fraction of such events. We observed a large spin-alignment for the {rho}{sup 0}-mesons selected as described above: The probability of zero spin projection onto the normal to the {rho}{sup 0} production plane is equal to {rho}{sup T}{sub 00}=0.86{plus minus}0.23. The enhancement of the number of events, in which the {rho}{sup 0} picks up practically full momentum transfer carrying by the exchange, and also the enlarged tensor polarization for the {rho}{sup 0}-mesons in these events could be qualitatively explained as manifestation of direct {rho}{sup 0}-production via the QCD higher twist processes in the high p{sub perpendicular} {sub to}(anti {pi})p collisions. At the same time, the observed effects are markedly larger, than the values predicted with QCD model, in which the higher twist corrections were included. (orig.).

    ção do anel ao se analisar exclusivamente a perda de peso.BACKGROUND: Use of ring in Roux-en-Y gastric bypass is still a matter of controversy among bariatric surgeons. There is no consensus on its impact in relation to weight loss and weight maintenance in the long term. AIM: To evaluate the influence of the ring on the evolution of body weight over four years after bariatric surgery. METHODS: Retrospective analyzis of 143 women who underwent laparoscopic Roux-en-Y gastric bypass paired on the use or not use of Silastic® ring. Follow-up time was 48 months. Inclusion criteria were age over 18 years, primary bariatric operation and regular attendance at the clinic during the period of interest for research. The technique kept small gastric reservoir estimated in a volume of 30 ml. The food limb had in average 150 cm and the bile one 40 cm from the duodenojejunal angle. The group "ring" used Silastic® device with length of 6.5 cm, placed 2 cm from gastrojejunal anastomosis. The ring was closed for five polypropylene surgical thread sutures. In the morning after surgery the patients received isotonic fluids; on the second day salty liquid diet and were discharged on the third day. Semisolid diet started from the 20th day and solid on the 30th, with daily tablet of polivitamins. RESULTS: The weight loss was larger on the ring than without ring groups in all periods, respectively 10% and only 5% in the third postoperative year. The proportion of not having reached the 50% excess weight loss expectative was significantly higher in the group without ring than in the group with the ring (31% and 8% respectively in the fourth year. There was no difference between groups in delayed recovery of weight lost with the operation. CONCLUSIONS: The results were favorable to use the ring exclusively when it is analyzed only the weight loss.

    Full Text Available At soybean production system, the interference of biotic and abiotic factors in the assimilation of carbon and nitrogen during the reproductive phase are the main determinants of grain yield and nitrogen input on cover crops justifies this management strategy.The aim of this work was evaluate at No-Tillagem System (NTS, with cover-crops and a soyben rotation, the contribution of the nitrogen fertilization to the improve of the straw, the yield and soybean grain composition. The treatments were: T1: triticum secale-IAC-2 (Zero N; T2: triticum secale (30 kg N ha-1 in coverage; T3: triticum secale (60 kg N ha-1 in coverage; T4: Chícharo (Latyrus sativum and T5: fallow in winter.We adjust the statical model analyzis in a design with randomized blocks and with four replications, at the Experimental Station Center (ESC-IAC-Santa Elisa above a Oxisol. The protein amount and the measures in the grains show that with added nitrogen in gains over fallow for yield and protein are obtained. Fallow has lower productivity of soybeans, valuing, even more the importance of maintaining the soil covered. Due to four years of implementation of the direct sowing system, the use of crops in the off season effectively demonstrates positive differences in soybean yield in relation to fallow (only spontaneous vegetation. The fact that well drive the system with dry matter intake in coverage for other crops in autumn-winter, already values the development of soybean in this system, when sown in summer. Na cultura de soja, a interferência de fatores bióticos e abióticos na assimilação de carbono e de nitrogênio na fase reprodutiva são os principais determinantes da produtividade de grãos, e aporte de nitrogênio em plantas de cobertura justifica esta estratégia de manejo. Com o objetivo de avaliar em sistema de semeadura direta (SSD culturas de cobertura em rotação com a soja e a contribuição da adubação nitrogenada para a formação de palhada além do
