  3. Study of the mutagenic potential of low power microwaves by direct DNA analyzis

    International Nuclear Information System (INIS)

    Man is constantly exposed to electromagnetic radiation which is a constituent part of the biosphere. Due to the technological progress and numerous man-made sources such as those used in industry, traffic, medicine, defence, communication network as well as some home appliances, the character of the natural electromagnetic field has altered significantly. These sources of nonionizing radiation cause atmospheric pollution similar to the pollution from various industrial sources. Unambiguous detection of the mutagenic potential of these radiations is necessary for genetic well being of future generations. (author)

Na stanovenie tychto zložiek boli využite spektrofotometricke metody Europskeho liekopisu, 8. vydanie. Zaroveň bol stanoveny aj obsah silice a bola vykonana analyza jej zložiek. Obsah celkovych polyfenolov bol stanoveny spektrofotometrickou metodou s využitim Folin-Ciocalteovho činidla. Obsah kolisal od 3.87 % do 8,86 %. Obsah trieslovin bol realizovany na zaklade predošleho stanovenia obsahu celkovych fenolov, a to adsorpciou trieslovin na kožny prašok. Ich obsah sa pohyboval v rozmedzi 1,96 % do 5,65 %. Na stanovenie obsahu flavonoidov bola využita spektrofotometricka metoda s chloridom hlinitym. Obsah flavonoidov vyjadrenych ako luteolin-7-O-glukozid (λ = 392 nm kolisal od 0,59 % do 1,52 % a obsah flavonoidov vyjadrenych ako rutin (λ = 420 nm sa pohyboval v rozmedzi od 0,41 % do 1,12 %. Antokyany zaberaju v ramci fenolovych zložiek rodu Thymus len minimalny podiel. V našich vzorkach bol obsah antokyanov vyjadreny ako cyanidin-3- O-glukozid a kolisal od 0,02 % do 0,1 %. Na stanovenie obsahu silice bola využita metoda Europskeho liekopisu, 8.vydanie. Obsah silice sa pohyboval v rozmedzi od 0,2 % do 0,75 %. Na analyzu silice bola nasledne využita metoda plynovej chromatografie s hmotnostnou spektrometriou. Na zaklade tejto analyzy bola zistena pritomnosť troch chemotypov silice, a to tymoloveho, karvakroloveho a linalooloveho chemotypu. Vďaka variaciami chemickeho zloženia silice, bolo možne pozorovať vzťah medzi pritomnosťou určiteho chemotypu a povodom vzorky. Rozdiely v stanoveni obsahu flavonoidov nepreukazali žiadny vyrazny vzťah k lokalite povodu.

  7. Web Application Security Detection of Misconfigurations in CERN servers

    CERN Document Server

    Durieux, Thomas

    2014-01-01

    CERN owns a large server farm (more than 10 000 servers). It's important to keep all servers configured and to detect vulnerabilities before malicious people. Considered the number of servers it is impossible to check them manually. So scripts are created to automatically detect vulnerabilities and misconfiguration. The final goal is to directly notify server administrator when issues are found. To achieve this goal, scripts must be extremely reliable in orther to not waste everyone's time. The reliability can only be reached by a long manually analyzis of CERN servers. The analyzis is also helping to determine the best way to detect issues and vulnerabilities.

    From smart homes that prepare coffee when we wake, to phones that know not to interrupt us during important conversations, our collective visions of HCI imagine a future in which computers understand a broad range of human behaviors. Today our systems fall short of these visions, however, because this range of behaviors is too large for designers or programmers to capture manually. In this paper, we instead demonstrate it is possible to mine a broad knowledge base of human behavior by analyzi...

    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...

  20. 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 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.
