    The objective of the present work was to develop, separately, methodology for production of two gaseous tracers through the sodium iodide NaI marked with 123 I. Found in the nature in form different, the iodine has been used in diverse works in the area of the industry and health. These two forms of the gaseous iodine, the methyl iodide, CH 3 I, and molecular iodine, I 2 , are very unstable and volatile in the ambient temperature and presents different problems in clean-up and monitoring systems. The syntheses were processed with sodium iodide (NaI) 1M aqueous solution marked with 1 23I . The production of gas I 2 was realized with in chlorine acid (HCl) and sodium iodate salt (NaIO 3 ) and the CH 3 I was used, the salt of NaI and the reagent (CH 3 ) 2 SO 4 . The production of gases was initially realized through in unit in glass with an inert material and the purpose was to study the kinetic of reaction and to determine the efficiency of production. The two synthesis occurs in the reaction bottle and after of produced, the gas is stored in the collect bottle that contains a starch solution for fixed the I 2 , and in syntheses of CH 3 I contains a silver nitrate solution for your fixation. To determine the efficiency of production of gases, analytic tests were realized, where the consumption of iodide ions of the bottle of reaction are measured. The optimization of production of the each gaseous tracer was studied varying parameter as: concentration of iodide, concentration of acid and temperature. After, the syntheses of the radiotracers were realized in the compact unit, having been used as main reagent the salt radiated of sodium iodide, Na 123 I. The transportation of elementary iodine and methyl iodine was studied by a scintillation detector NaI (2 x 2)' positioned in the reaction bottle. (author)

  7. Single-molecule study of full-length NaChBac by planar lipid bilayer recording.

    Directory of Open Access Journals (Sweden)

    Andrew Jo

    Full Text Available Planar lipid bilayer device, alternatively known as BLM, is a powerful tool to study functional properties of conducting membrane proteins such as ion channels and porins. In this work, we used BLM to study the prokaryotic voltage-gated sodium channel (Nav NaChBac in a well-defined membrane environment. Navs are an essential component for the generation and propagation of electric signals in excitable cells. The successes in the biochemical, biophysical and crystallographic studies on prokaryotic Navs in recent years has greatly promoted the understanding of the molecular mechanism that underlies these proteins and their eukaryotic counterparts. In this work, we investigated the single-molecule conductance and ionic selectivity behavior of NaChBac. Purified NaChBac protein was first reconstituted into lipid vesicles, which is subsequently incorporated into planar lipid bilayer by fusion. At single-molecule level, we were able to observe three distinct long-lived conductance sub-states of NaChBac. Change in the membrane potential switches on the channel mainly by increasing its opening probability. In addition, we found that individual NaChBac has similar permeability for Na+, K+, and Ca2+. The single-molecule behavior of the full-length protein is essentially highly stochastic. Our results show that planar lipid bilayer device can be used to study purified ion channels at single-molecule level in an artificial environment, and such studies can reveal new protein properties that are otherwise not observable in in vivo ensemble studies.

    Full Text Available O chá é uma das bebidas mais consumidas no mundo, vem sendo utilizado pela população como coadjuvante no tratamento da redução de peso, uma vez que aumenta a termogênese e em muitos casos promove a saciedade. O objetivo deste trabalho foi mostrar como as catequinas do chá verde auxiliam no tratamento da obesidade. Foram realizadas buscas por artigos científicos nas bases de dados Science Direct, Google Acadêmico, Scielo, BVS, Medline e Wilson. Os artigos escolhidos foram publicados no período de 2000 a 2014. Observa-se que o tratamento da obesidade envolve necessariamente a reeducação alimentar, o aumento da atividade física e eventualmente, o uso de algumas medicações auxiliares. Outra alternativa, é o uso de fitoterápicos como por exemplo o chá verde. Estudos têm mostrado que este chá, que é obtido pela infusão da erva Camellia sinensis é rico em catequinas, responsáveis na redução de peso, pois promovem a termogênese e aumentam a saciedade. A epigalocatequina (EGCG, é a catequina mais abundante e mais forte do chá verde. É importante ressaltar que o chá usado de maneira inadequada pode causar hepatotoxicidade. O uso do chá associado a um plano alimentar equilibrado pode trazer benefícios à saúde além da perda de peso. Porém os estudos ainda não são conclusivos, sendo necessários mais estudos para que possa confirmar a eficácia do chá verde na obesidade e a quantidade a ser utilizada. Entretanto, a reeducação alimentar, exercício físico continuam sendo os fatores mais importantes no tratamento da obesidade, Onde o consumo de chá verde deve está associado a uma alimentação saudável.

  12. Molecular simulation of preferential adsorption of CO2 over CH4 in Na-montmorillonite clay material

    Science.gov (United States)

    Yang, Nannan; Liu, Shuyan; Yang, Xiaoning

    2015-11-01

    Grand canonical Monte Carlo simulations have been conducted to study the adsorption of carbon dioxide and methane, as well as their binary mixtures on Na-montmorillonite clay material. It was found that the adsorption behavior near the clay structure for the two species is distinctively different. The Na-montmorillonite clay shows obviously high adsorption capacity for CO2, as compared with CH4. The adsorption behavior and mechanism have been characterized by the interlayer interfacial structures and isosteric heats of adsorption. Meanwhile, the mixture adsorption demonstrates that CO2 molecules with enhanced adsorption strength are able to competitively replace CH4 molecules within the clay structure. The high separation selectivity of CO2 over CH4 implies the possibility of separating CO2 from natural gas mixtures using the clay minerals. The interlayer sodium cations and negatively charged clay surface can provide enhanced interaction with CO2 molecules that have high quadrupole moment, which is responsible for the higher adsorption loading of CO2.

  14. Chiroptical luminescence spectra of UO22+ in cubic Na[UO2(CH3COO)3] crystals

    International Nuclear Information System (INIS)

    Moran, D.M.; Metcalf, D.H.; Richardson, F.S.

    1992-01-01

    Steady-state chiroptical luminescence measurements are reported for cubic crystals of Na[UO 2 (CH 3 COO) 3 ]. These crystals belong to the enantiomorphic space group P2 1 3, with four molecules per unit cell, and each UO 2 (CH 3 COO) 3 - coordination unit has a chiral tris-bidentate chelate structure of C 3 symmetry. The UO 2 O' 6 coordination clusters (where O' denotes an acetate oxygen donor atom) also have chiral structures of C 3 point-group symmetry, but they deviate only slightly from an achiral D 3h symmetry. The luminescence observed for Na[UO 2 (CH 3 COO) 3 ] is assigned to transitions that originate from the lowest electronic excited state (II g ) of UO 2 2+ and terminate on the ground electronic state (Σ g + ). At least two types of UO 2 2+ species contribute to this luminescence, but the luminescence spectra can be analyzed in terms of separate majority species (or bulk site) contributions and minority species (or defect site) contributions. The luminescence spectra show zero-phonon origin lines, one-phonon false-origin lines, and vibronic progressions in the symmetric stretching mode (ν s ) of UO 2 2+ . The false-origin lines and the progressions based on these lines are essentially unpolarized. However, the origin lines and their progressions exhibit a very large degree of circular polarization, with emission dissymmetry factors of g em = 1.31 (majority species) and g em = 0.96 (minority species). The circularly polarized luminescence results for Σ g + left-arrow II g emission are compared to circular dichroism results for Σ g + → II g absorption, and the distribution of Σ g + ↔ II g electronic rotary strength among origin and vibronic lines is discussed within the context of vibronic optical activity theory

[VÝCHODISKA: Za jedno z hlavních kritérií nezbytné vnitřní diferenciace tělovýchovného procesu na základních školách praktických je považován stupeň mentálního postižení žáků. Doposud však dětem s mentálním postižením, resp. žákům základních škol praktických nebyl v tomto ohledu věnován dostatek pozornosti jak v oblasti výzkumného bádání, tak v tělovýchovné praxi. CÍLE: Cílem realizované studie bylo zjistit úroveň vybraných koordinačních schopností 153 žáků (ve věku 9–11 let na základních školách praktických v Praze s ohledem na stupeň jejich mentálního postižení. METODIKA: K posouzení úrovně vybraných koordinačních schopností bylo použito sedm motorických testů (rytmické, rovnováhové, kinesteticko-diferenciační schopnosti, schopnosti přestavby a sdružování. VÝSLEDKY: Téměř naprosto jednoznačně byly věcně významné rozdíly (užitím Cohenova koeficientu d prokázány mezi žáky s intelektovými schopnostmi v oblasti dolní hranice lehkého mentálního postižení a ostatními s výjimkou těch, jejichž intelektové schopnosti se pohybují na horní hranici lehkého mentálního postižení, a dále mezi těmito žáky a ostatními (hluboký intelektový podprůměr, lehký intelektový podprůměr, průměrné intelektové schopnosti - nižší průměr. Z hlediska průměrných hodnot motorických výkonů lze sledovat jejich přímou vazbu k míře mentálního postižení - klesají s jejím růstem. Nejlepší testová skóre byla překvapivě zaregistrována u žáků s lehkým intelektovým podprůměrem, a nikoliv u žáků s nejvyšší úrovní intelektových schopností. ZÁVĚRY: Rozdílné výsledky v motorických testech žáků základních škol praktických nejsou ryze kauzálně závislé pouze na stupni mentálního postižení, ale i na jeho etiologii.

    The objective of the present work was to develop, separately, methodology for production of two gaseous tracers through the sodium iodide NaI marked with {sup 123}I. Found in the nature in form different, the iodine has been used in diverse works in the area of the industry and health. These two forms of the gaseous iodine, the methyl iodide, CH{sub 3}I, and molecular iodine, I{sub 2}, are very unstable and volatile in the ambient temperature and presents different problems in clean-up and monitoring systems. The syntheses were processed with sodium iodide (NaI) 1M aqueous solution marked with 1{sup 23I}. The production of gas I{sub 2} was realized with in chlorine acid (HCl) and sodium iodate salt (NaIO{sub 3}) and the CH{sub 3}I was used, the salt of NaI and the reagent (CH{sub 3}){sub 2}SO{sub 4}. The production of gases was initially realized through in unit in glass with an inert material and the purpose was to study the kinetic of reaction and to determine the efficiency of production. The two synthesis occurs in the reaction bottle and after of produced, the gas is stored in the collect bottle that contains a starch solution for fixed the I{sub 2}, and in syntheses of CH{sub 3}I contains a silver nitrate solution for your fixation. To determine the efficiency of production of gases, analytic tests were realized, where the consumption of iodide ions of the bottle of reaction are measured. The optimization of production of the each gaseous tracer was studied varying parameter as: concentration of iodide, concentration of acid and temperature. After, the syntheses of the radiotracers were realized in the compact unit, having been used as main reagent the salt radiated of sodium iodide, Na{sup 123}I. The transportation of elementary iodine and methyl iodine was studied by a scintillation detector NaI (2 x 2)' positioned in the reaction bottle. (author)

    Avian leukosis virus subgroup J (ALV-J), first isolated in the late 1980s, has caused economic losses to the poultry industry in many countries. As all chicken lines studied to date are susceptible to ALV infection, there is enormous interest in developing resistant chicken lines. The ALV-J receptor, chicken Na + /H + exchange 1 (chNHE1) and the critical amino acid sequences involved in viral attachment and entry have already been characterized. However, there are no reported attempts to induce resistance to the virus by targeted genome modification of the receptor sequences. In an attempt to induce resistance to ALV-J infection, we used clustered regularly interspaced short palindromic repeats (CRISPR)-associated (CRISPR/Cas9)-based genome editing approaches to modify critical residues of the chNHE1 receptor in chicken cells. The susceptibility of the modified cell lines to ALV-J infection was examined using enhanced green fluorescent protein (EGFP)-expressing marker viruses. We showed that modifying the chNHE1 receptor by artificially generating a premature stop codon induced absolute resistance to viral infection, with mutations of the tryptophan residue at position 38 (Trp38) being very critical. Single-stranded oligodeoxynucleotide (ssODN)-mediated targeted recombination of the Trp38 region revealed that deletions involving the Trp38 residue were most effective in conferring resistance to ALV-J. Moreover, protein structure analysis of the chNHE1 receptor sequence suggested that its intrinsically disordered region undergoes local conformational changes through genetic alteration. Collectively, these results demonstrate that targeted mutations on chNHE1 alter the susceptibility to ALV-J and the technique is expected to contribute to develop disease-resistant chicken lines.

    Full Text Available [VÝCHODISKA: Sportovní výkon v přeskoku trvá krátký čas a je ovlivněn množstvím biomechanických proměnných. Po Olympijských hrách v roce 2000 bylo tradiční přeskokové nářadí nahrazeno moderním přeskokovým stolem. V současné době nejsou známy komplexní biomechanická data o přeskocích při použití nového přeskokového stolu a je otázkou, jaké je současné provedení přemetových přeskoků u vrcholových sportovních gymnastek. CÍLE: Cílem studie je určit, které biomechanické faktory se podílejí na úspěšném provedení přemetových skoků. METODIKA: Výzkumu se účastnilo osm vrcholových sportovních gymnastek. Pro 3D prostorovou analýzu byly použity dva digitální kamkordéry se snímkovací normou 50 půlsnímků/s. Data byla digitalizována pomocí softwaru Simi motion. Metoda podle Hay a Reid (1988 byla použita pro identifikaci biomechanických proměnných, které ovlivňují průběh přemetových skoků. Pro posouzení závislosti mezi biomechanickými proměnnými a bodovým hodnocením byla použita korelační analýza. Hladina statistické významnosti byla nastavena na hladinu p < 0,05. VÝSLEDKY: Z 23 vyšetřovaných proměnných byly u pěti zjištěny signifikantní korelace s bodovým hodnocením. Signifikantní korelace byla zjištěna u vertikální výšky těžiště těla při odrazu z přeskokového stolu (r = 0,86, maximální výšky těžiště těla ve druhé letové fázi (r = 0,83, změně horizontální rychlosti ve fázi odrazu z přeskokového stolu (r = -0,69, u horizontální složky rychlosti při odrazu z přeskokového nářadí (r = 0,75 a doby trvání druhé letové fáze (r = 0,69. ZÁVĚRY: Fáze odrazu z přeskokového stolu je klíčovou fází skoku. Vrcholové sportovní gymnastky dokáží provést odraz z přeskokového stolu v relativně krátkém časovém úseku a v plném rozsahu pohybu (maximalizace výšky těžiště těla při odrazu

    Full Text Available Molekulární biologie je rychle se rozvíjející vědní obor a s jejími metodami se setkáváme i v každodenním životě. Proto je důležité, aby byla zastoupena ve výuce biologie na gymnáziích. Jedním z cílů studie bylo analyzovat rozložení vzdělávacího obsahu molekulární biologie na úrovni gymnaziálních školních vzdělávacích programů (ŠVP do jednotlivých ročníků a zjistit, která molekulárně biologická témata jsou v ŠVP zastoupena a jak často. Dalším cílem bylo otestovat srozumitelnost a atraktivitu pokročilých molekulárně biologických laboratorních cvičení určených pro žáky střední školy. ŠVP celkem 160 gymnázií ze všech krajů ČR byly hodnoceny z hlediska zařazení deseti tematických kategorií výukového obsahu molekulární biologie ve vyučovacích předmětech biologie, chemie a volitelných biologických a chemických seminářích. Data byla analyzována shlukovou analýzou a následným χ2 testem nezávislosti. V letech 2011–2013 byly realizovány čtyři různé typy praktických cvičení z molekulární biologie, kterých se zúčastnilo 466 žáků středních škol. Cvičení probíhala buď na Přírodovědecké fakultě Univerzity Karlovy v Praze, nebo na středních školách, vedl je vysokoškolský lektor nebo středoškolský učitel. Po ukončení cvičení žáci vyplnili reflektivní dotazník, ve kterém laboratorní cvičení zhodnotili. Získaná data byla zpracována pomocí analýzy rozptylu. Výsledky ukazují, že molekulárně biologická témata jsou do výuky na gymnáziích zařazena převážně izolovaně v posledním ročníku povinné výuky biologie či chemie. Řada témat je v rámci povinné výuky opomíjena, případně je zařazena pouze v povinně volitelných seminářích. Realizovaná molekulárně biologická cvičení byla žáky celkově hodnocena velmi kladně.

Martin Pupiš je jedním z těch atletů, kteří pravidelně využívají tento systém. V tomto příspěvku popisujeme jeho přípravu ve čtyřech vysokohorských kempech v přípravných fázích v letech 1998/1999–2001/2002. Části roku, ve kterých se kempy odehrávaly, byly velmi podobné. Doba trvání byla rovněž stejná od 26 do 36 dnů. Průměrné množství závodní chůze a běhu bylo v rámci jednoho dne přibližně stejné během všech čtyř kempů. Poměr závodní chůze v kilometrech se zvýšil ze 70% na 80%. Podíl oblastí pro chůzi se měnil v závislosti na aktuální specializaci s nejvyšším počtem kilometrů ve vytrvalosti tempa. Reakce na přípravu ve vyšší nadmořské výšce byla velmi dobrá; když jsme analyzovali krevní složky – hematokrit, hemoglobin, erytocyty, střední množství erytocytů – zaznamenali jsme pozitivní změny; pouze u leukocytů nastal pokles. Middle and high altitude preparation is a longterm part of the preparation of our Slovak race walking representatives. Martin Pupiš is one of those athletes whose regularly makes use of this system. In our paper we report his preparation at four high altitude camps, in preparation phases in the years 1998/99–2001/02. The period of the year when the camps took place were very similar. Also the duration was from 26 days to 36 days. The average amount of racewalking and running was, for one day, approximately the same during all four camps. The proportion of race walking in kilometres increased from 70% to 80%. The proportion of walking zones changed depending on the current specialisation with the highest number of km in tempo endurance.

    - Adequate bowel preparation is critical for the quality of colonoscopy. Despite reported occurrence of colonic explosion due to methane and hydrogen production by bacterial fermentation during colonoscopy, gas exchange during the procedure is believed to be effective in lowering existing methane concentration, allowing for safe utilization of mannitol for bowel preparation. Thus, mannitol is widely used for bowel cleansing prior to colonoscopy, considering its low cost and effectiveness for bowel preparation. - The aim of this study was to assess the safety of mannitol for bowel preparation, when compared to sodium phosphate (NaP). - We conducted a prospective observational study in which 250 patients undergoing colonoscopy at Universidade Federal de São Paulo and Hospital Albert Einstein (São Paulo, Brazil) were approached for inclusion in the study. Patients received either mannitol (n=50) or NaP (n=200) for bowel preparation, based on physician indication. Study was conducted from August 2009 to December 2009. The main outcome of interest was presence of detectable levels of methane (CH4) during colonoscopy and reduction in such levels after gas exchange during the procedure. Methane concentrations were measured in three intestinal segments during scope introduction and withdrawal. Safety was assessed as the absence of high levels of methane, defined as 5%. Measurements were made using a multi-gas monitor (X-am 7000, Dräger Safety AG & Co. KGaA, Lübeck, Germany) connected to a plastic catheter introduced into the working channel of the colonoscope. Additional outcomes of interest included levels of O2. Methane and O2 levels are reported as ppm. Mean, difference and standard deviation of levels of gas measured in both moments were calculated and compared in both groups. Proportions of patients with detectable or high levels of methane in both groups were compared. Continuous variables were analyzed using t test and categorical variables using qui

    Full Text Available Vzdělaní lidé, zejména pak vysokoškolští studenti mají lepší přístup k informacím o důležitosti plnění zdravotních doporučení k pohybové aktivitě a jejich významnosti pro zdravý a aktivní životní styl. Cílem studie je zjistit, zda univerzitní studenti v České republice plní tato doporučení a které demografické ukazatele mají největší vliv na jejich plnění. Pro šetření byl využit mezinárodní dotazník pohybové aktivity (IPAQ – krátká verze a do logistické regresní analýzy vstoupily údaje z dotazníků od 2400 českých vysokoškolských studentů. Jako nezávislé proměnné jsme zvolili: (a zda plní doporučení pro intenzivní PA (3 × 20 minut týdně či ne, (b zda plní doporučení pro středně zatěžující PA (5 × 30 minut týdně a (c zda plní doporučení pro chůzi (5 × 30 minut týdně. Mezi závislé proměnné, které mohou splnění těchto doporučení ovlivňovat, jsme z dotazníku zařadili věk, pohlaví, BMI, místo bydliště, způsob bydlení, způsob života, kouření, vlastnictví auta nebo kola a pravidelnou účast v organizované PA. Z analýzy vyplynulo, že nejvýznamnějším faktorem, který ovlivňuje plnění doporučení PA, jednoznačně patří pravidelná účast v organizované PA. Větší pravděpodobnost, že splní doporučení PA, mají muži, jednadvacetiletí studenti a ti studenti, kteří žijí na vesnici, v rodině, nekouří a vlastní kolo. Více než 85 % českých vysokoškolských studentů splnilo obecná doporučení PA, ale přesto je potřeba posílit propagaci o vhodném množství prováděné středně zatěžující pohybové aktivitě, jelikož příslušné doporučení splnilo pouze 19 % studentů. Educated people have got better information about the importance of a proper amount of physical activity, but whether Czech university students meet recommendations for physical activity is not clearly known.

    CHODISKA: Existuje několik faktorů (počáteční poloha skokana na lyžích a její změny v průběhu přechodové fáze letu, velikost a směr vektoru rychlosti pohybu těžiště skokana, velikost aerodynamické odporové a vztlakové síly apod., které určují trajektorii soustavy skokan + lyže a tím i dosaženou délku skoku. CÍLE: Cílem studie je představit metodu řešení úlohy optimálního řízení letové fáze skoku na lyžích se třemi omezenými řídicími proměnnými – úhel náběhu (a, úhel trup vs. lyže (b, úhel levá lyže vs. pravá lyže (V – na základě Pontrjaginova principu maxima. METODIKA: Kritériem optimality byla zvolena délka skoku. Jako zdroj informací o závislosti veličin L (lift area a D (drag area na řídicích proměnných byla použita převzatá regresní funkce s tabelovanými regresními koeficienty. Srovnány byly trajektorie referenčního a optimalizovaného skoku s profilem můstku K = 125 m ve Frenštátě pod Radhoštěm a stanoveny odpovídající délky skoku, aerodynamické odporové a vztlakové síly, velikosti rychlosti pohybu těžiště soustavy skokan + lyže, její vertikální a horizontální složky. Aby byly respektovány reálné polohy v letové fázi skoku, přípustné hodnoty řídicích proměnných náležely v každém okamžiku ohraničené množině. VÝSLEDKY: Bylo zjištěno, že skokan by měl na ohraničené množině přípustných hodnot řídicích proměnných minimalizovat úhly (a a (b, úhel (V naopak maximalizovat. Prodloužení skoku vlivem optimalizace je 17 %. ZÁVĚRY: Pro možnost dalšího výzkumu je nezbytné využití regresní analýzy pro experimentální data při určení závislosti aerodynamických sil působících během letu na soustavu skokan + lyže. To platí také pro aplikaci kontrolních proměnných vztahujících se k základním fyzickým a psychickým vlastnostem skokanů na lyžích.

    Full Text Available Resumo No âmbito empresarial, as estratégias de marketing voltadas para assuntos relacionados à nutrição têm sido a principal vantagem competitiva. Diante disso, o objetivo deste trabalho foi avaliar a influência de características sensoriais e do conhecimento nutricional na aceitação do chá-mate, visando identificar o comportamento do consumidor frente a este tipo de informação. Foi utilizado chá-mate tostado, tipo a granel, adquirido no comércio local e preparado de acordo com a recomendação descrita na embalagem. Para o teste afetivo de aceitação, foram recrutados 30 consumidores do produto. O recrutamento ocorreu por meio de um questionário abrangendo questões sobre o perfil dos consumidores, hábitos de consumo e disponibilidade para participar da pesquisa. Foram realizadas avaliações de aceitação sensorial em duas sessões (teste cego e com informação, utilizando-se uma escala hedônica de nove pontos, para avaliar os atributos cor, sabor, aroma e impressão global. Em relação ao perfil dos julgadores, 67% pertenciam ao sexo feminino, 50% relataram consumir chá-mate raramente e 37% afirmaram observar as informações nutricionais no rótulo. Houve diferença significativa para os atributos cor e sabor, entre as sessões cega e com informação. Pode-se concluir que o chá-mate apresentou boa aceitação pelos participantes e que o conhecimento nutricional influenciou positivamente na aceitação da bebida.

CONCLUSIONS: In conclusion, the findings have indicated that there exists variability in patterns of muscle activation during the step up task.[VÝCHODISKA: Nákrok na schod je součástí běžných denních motorických aktivit. Při jeho provádění musí být tělo schopno udržovat rovnováhu a stabilní vzpřímenou posturu za současného průběhu volního pohybu. K tomuto účelu vytváří centrální nervová soustava různé motorické programy, specifické pro daný úkol a obsahující předem programované sekvence zapojování svalů k zajištění provedení vlastního pohybu a k udržení postury během vykonávaného pohybu. CÍLE: Cílem práce bylo určení časové posloupnosti zapojení vybraných svalů trupu a dolních končetin při nákroku na schod. Dalším cílem bylo zjištění nejběžnějšího vzoru zapojování svalů v této modelové pohybové aktivitě u zdravých osob. METODIKA: U této práce byla snímána bilaterálně elektromyografická aktivita m. gluteus maximus, m. biceps femoris a m. erector spinae (v jeho lumbální části. Spolu s elektromyografickým signálem snímaným povrchovými elektrodami byl zaznamenáván i vizuální záznam provedení nákroku na schod.

The schools and the teachers belong to the public teaching service of São Paulo state, in the cities of Presidente Prudente-SP and Araçatuba-SP. The Education Department of São Paulo (SEE / SP carried out such an intervention enabling its faculty in 2003 and 2004, effecting the practice of Lien Ch`i during the years 2005, 2006 and 2007. The current National Curricular Parameters (PCN's suggest splitting the content of physical education in three blocks, a sports, games, wrestling and gymnastics, b Rhythmic and expressive Activities, c knowledge about the body. Due to its rich job options, the Lien Ch`i may be inserted into any of the three blocks mentioned above. Added to these aspects, our interest was keen to investigate the characteristics of this modality and its effectiveness, motivation and acceptance of the people involved in the process.

    Full Text Available Prevence představuje nejúčinnější prostředek proti užívání drog. Na jedné straně vytváří tělesná aktivita řadu faktorů, které vedou k přijetí zdravých stravovacích návyků, na druhé straně představuje prevenci užívání drog, protože sama o sobě určitým způsobem stimuluje tělo i mysl. Cílem provedeného výzkumu bylo stanovit stupeň obeznámenosti s návykovými látkami a jejich užíváním (například cigarety, alkohol a marihuana u dětí ve vztahu k frekvenci jejich zapojení do sportovních aktivit. Vzorek obsahoval 748 dětí, z čehož bylo 194 žáků a 189 žákyň čtvrtých tříd (jejichž průměrný věk byl 10 let ± 5 měsíců, a 201 žáků a 164 žákyň sedmých tříd (jejichž průměrný věk byl 13 let ± 4 měsíce. Uvedené údaje byly získány v rámci projektu "Tělesná/sportovní aktivita pro zdraví" probíhajícího v Ústavu kinesiologického výzkumu ve Vědeckém a výzkumném středisku Primorske univerzity ve slovinském Koperu. Použili jsme dotazník IPAQ (International Physical Activity Questionnaire, který jsme poněkud upravili pro věk a specifické vlastnosti respondentů. Pro stanovení vztahu mezi nečíselnými proměnnými jsme použili korespondenční analýzu. Pro číselné proměnné jsme použili analýzu variance a t-testy nezávislých vzorků. Všechny hypotézy byly ověřovány s 5% statistickou úrovní rizika (p = 0,05. Výsledky potvrdily u žáků statisticky významný vztah mezi sportovní aktivitou, kouřením a užíváním alkoholu a marihuany. Faktem je, že i když problém užívání drog nemůže být zcela odstraněn, mohli bychom ho zásadním způsobem redukovat. Jedním z nejdůležitějších faktorů pro snižování užívání drog je proto rovněž zapojení mládeže do vhodných sportovních aktivit (zvláště ve volném čase, což by mělo být řízeno a plánováno rodiči a učiteli.

    Full Text Available V šetření TIMSS 2011 se objevil index nazvaný „důraz školy na studijní úspěch“ (SEAS. Cílem článku je osvětlit skutečnost, že české školy vykazují poměrně nápadné hodnoty tohoto indexu. Dále pomocí SEAS analyzuje vztah mezi postoji českých škol k reformě a znalostmi a dovednostmi jejich žáků. Teoretický úvod popisuje konstrukt akademický optimismus a index SEAS zavedený v šetření TIMSS. Následně je provedena explorativní sekundární analýza dat o úrovni složek SEAS v případě českých škol se zaměřením na nápadné odchylky hodnot. Práce vychází z výsledků žáků čtvrtých ročníků v matematickém testu TIMSS 2011 a z odpovídajících učitelských a ředitelských dotazníků. Pro analýzu vztahů v datech jsou použity základní prostředky popisné a inferenční statistiky. Zjištění ukazují na disproporčně nízkou důvěru ředitelů ve snahu žáků ve škole dobře prospívat, která je společná regionálnímu klastru zemí. Dále analýza přinesla nečekaná zjištění o vztahu mezi postoji ředitelů a učitelů ke kurikulární reformě a výsledky jejich žáků v matematice. Z literatury známá i naše původní zjištění o komponentách indexu SEAS v podmínkách českých škol přinášejí zajímavé pohledy mj. na vnímání reformních procesů v českých školách a doplňují tak literaturu o implementaci, resp. recepci reformy.

Alternative hypothesis was presumption, that the lying time of cows in lying cubicles with applied two different cooling systems are indifferent. The sprinkling system was used to animal cooling in group S in summer time. In group SV was disposable sprinkling system and diagonally rotated ventilators. Activities and the rest of animals were evaluated in 10 minute intervals using a camera system for 24 hours. Data obtained was tested by nonparametric Kruskal-Wallis one-way ANOVA and multiple comparison test for detecting of significant differences in the behaviors between groups of cows. There was found positive effect of animal enhanced cooling using sprinkling system with increased air movement by ventilators. It reflected in significant prolongation of whole lying time and shortening of time, when animals were standing. It resulted from final values of investigated behaviour manifestations of dairy cattle within 24 hour period that animals in group SV with sprinklers and ventilators lay in stalls longer than in group S with sprinklers, but without ventilators (10.76 h*d-1*cow-1 vs. 7.71 h*d-1*cow-1, P<0.001. The total time spent by lying in stalls and in alley represented in group SV 11.31 h*d-1*cow-1, and in group S 10.22 h*d-1*cow-1.

    Full Text Available BACKGROUND: Obtaining a long jumping distance is necessary in order to succeed among the best competitors in the Nordic combined. The body movement during the take-off and early flight is considered to be the most important factor for length of the jump. OBJECTIVE: The purpose of this study was to assess the technique of the start of the early flight phase among three groups of Nordic combined competitors representing different performance levels, and to compare them with a group of ski jumpers. METHODS: Thirty competitors from both sport disciplines (Nordic combined and ski jumping, who performed ski jumps using an HS-134 m jumping hill during the 2009 Nordic World Ski Championships in Liberec, were divided into three subgroups based on jump length. Two-dimensional kinematic data were collected for the lower extremities, the trunk, and the skis of the competitors. RESULTS: The elite Nordic combined group showed a greater in-run velocity than did the two other performance groups (p CONCLUSIONS: The results indicated that ski jumping competitors took a better aerodynamic position in the section 0-5 m behind the edge of the jumping hill. The Nordic combined competitors used a higher average in-run velocity to achieve ski jump length comparable to those of ski jumpers.[VÝCHODISKA: Dosažení kvalitního výkonu ve skoku na lyžích je nezbytným předpokladem pro výsledné umístění v závodech severské kombinace.

Green tea polyphenols have demonstrated to be an effective chemopreventive agent. Recently, investigators have found that EGCG, one of the green tea catechins, could have anti-HIV effects when bound to CD4 receptor. Many factors can constitute important influences on the composition of tea, such as species, season, age of the leaf, climate, and horticultural practices (soil, water, minerals, fertilizers.

    Full Text Available Jednou z bariér, týkající se začlenění dětí s postižením do tělesné výchovy, mohou být negativní postoje učitelů. Tyto postoje mohou pramenit z neznalosti nebo nedostatku zkušeností s dětmi s postižením. Pro překonání těchto bariér je nezbytné změnit postoje těch, kteří mají být prostředníky v inkluzi. Tripp a Sherrill (1991 opakovaně vyzdvihují význam postojů v aplikovaných pohybových aktivitách a jejich výzkumu. Teoreticky podložený výzkum o utváření postojů může stanovit rámec porozumění faktorům, které působí na vztah mezi postojem a chováním (Tripp & Sherrill, 1991. V rámci výzkumu postojů jsme upravili dotazník "Attitude Toward Teaching Individuals with Physical Disabilities in Physical Education" (ATIPDPE pro studenty oboru "sport science" na Universitě Stellenbosch v Jihoafrické republice. Do výzkumu bylo začleněno 60 studentů. Utvořili jsme dvě skupiny, ve kterých bylo 30 studentů se specializací trenérství osob se zdravotním postižením a 30 studentů bez této specializace. Porovnali jsme skupiny v komponentech teorie plánovaného jednání a výsledky ukázaly, že mezi postoji studentů v těchto dvou skupinách není statisticky významný rozdíl. The Republic of South Africa has undergone significant changes with regard to people with disabilities in the past number of years, which have also included changes in legislation and education. In the education of children with disabilities, inclusion is quite a new phenomenon. In order to prepare for inclusion, universities must focus on teacher preparation. Sherrill (1998 emphasised the role of attitudes in teacher preparation and therefore we have focused on the attitudes of university students toward inclusion. The aim of this study was to examine the differences in attitudes between two groups of students of the Department of Sport Science at the University of Stellenbosch in the Republic of South

It further results from the assessment that postures D and F significantly reduce postural sway towards posture A and posture F further reduces postural sway towards posture D. [VÝCHODISKA: Při vyšetřování tvaru páteře jak rentgenologickými, tak neradiačními neinvazivními metodami je důležitá standardizace polohy vyšetřované osoby. CÍLE: Standardizace vyšetřovací polohy umožní vzájemné porovnání výsledků vyšetření různými metodami. Navíc vhodná vyšetřovací poloha by měla snížit titubaci a tím zvýšit reliabilitu vyšetření. METODIKA: Pro hodnocení vlivu fixace na snížení titubace vyšetřované osoby byly navrženy dvě vyšetřovací polohy s různým stupněm fixace: poloha D – stoj s oporou ramen o fixační rám a poloha F – leh na břiše na fixačním lůžku. Uvedené polohy byly porovnány s polohou A – volný návykový stoj. Pro vyšetření tvaru páteře a titubace byl využit mikropočítačový diagnostický systém DTP-3, který umožňuje měřit třírozměrnou polohu bodů neinvazivní dotykovou metodou. Metodika vyšetření spočívá v palpaci a označení projekcí akromionů, zadních horních spin a trnových výběžků na kožním povrchu vyšetřované osoby. Označené body jsou snímány dotykem hrotu polohového snímače a přenášeny do osobního počítače, kde jsou zobrazeny do výstupních protokolů ve formě tabulek a grafů. Byl změřen soubor 80 vyšetřených osob (40 mužů a 40 žen, věk 23,1 ± 2,5 roku. Každá osoba byla v každé vyšetřovací poloze změřena pětkrát a byla vypočítána průměrná křivka páteře a standardní odchylka kvantifi kující titubaci vyšetřované osoby.

    Full Text Available Casas de lata, flores de plástico, cascas de árvore feitas de crochê, animais mecanicamente animados. . . O cenário colorido e repleto de fantasia da segunda versão da novela “Meu Pedacinho de Chão” (Rede Globo, 2014 é um convite à reflexão sobre o imaginário. Trata-se de uma produção da teledramaturgia brasileira que aposta em uma linguagem diferente, sobretudo no aspecto visual. Ao privilegiar um cenário que se identifica com o universo da imaginação infantil, oferece margem para se pensar numa representação que não encontra correspondência direta com o suposto mundo real. Neste trabalho, apresenta-se a análise da chamada da novela e os aspectos da narrativa que seduzem o telespectador. A tecnologia apresenta-se como ferramenta de atualização da narrativa, criando um cenário atemporal, fantasioso e sedutor, já presente no imaginário

    Full Text Available Odvodili sa modely výškových kriviek z experimentálneho materiálu opakovaných meraní šiestich trvalých výskumných plôch na výskumnom objekte Komárnik vo Východných Karpatoch. Počas viac ako 50-ročného sledovania sa zmeralo 1 346 výšok pre buk a 1 208 pre jedľu. Výšky majú všeobecne veľkú variabilitu, ale nepreukázal sa štádiový posun výškových kriviek. Odvodili sa nelineárne regresné modely výškových kriviek pre buk a jedľu, kde výška stromu je funkciou jeho hrúbky a modelovej výšky pre zvolený hrúbkový stupeň. Ich základom je Korfova rastová krivka s tromi parametrami. Modelom je vysvetlených 90 % variability výšok pri buku a 94 % pri jedli. Modely potvrdili doterajšie poznatky, že jedľa má najmä pri hrubších stromoch vyššie výškové prírastky ako buk. V porovnaní k modelom iných autorov majú odvodené modely málo odlišný tvar výškových kriviek. Buk má väčšiu a jedľa menšiu krivosť ako porovnávané modely. Modely majú vzhľadom na obmedzený rozsah experimentálneho materiálu len lokálny charakter. Pre miestne pomery sa môžu aplikovať na bonitovanie a simulovanie vývoja zásob a prírastku nerovnovekých a viacetážových jedľovo-bukových porastov.

Essa explicação toma, no interior de seu complexo sistema arquitetônico de pensamento, a tendência à aquisição de hábitos como o princípio explicativo fulcral sobre a origem e a evolução das Leis da Natureza. Peirce adota tal princípio como aquele que sustentaria uma afinidade entre mente e matéria

    Full Text Available Cílem této studie bylo určit tělesné složení a úroveň motorické výkonnosti a zároveň posoudit změny v komponentách tělesného složení a v úrovni motorické výkonnosti v závislosti na pravidelném tréninkovém zatížení aplikovaném v rámci šestiměsíčního tréninkového programu přípravném období, tzv. "suché přípravy", ročního tréninkového cyklu 2003/2004 u skupiny mladých lyžařů běžců, žáků sportovních tříd při ZŠ T. G. Masaryka ve Vimperku a členů lyžařských oddílů Ski-klub Šumava, Libín Prachatice a Sokol Stachy ve věku 12–15 let (n = 81, v porovnání s normální populací (n = 49. Byla provedena dvě měření tělesného složení a motorické výkonnosti, na začátku a konci přípravného období (duben a říjen, tedy podruhé po šestiměsíčním tréninkovém programu. Metodou pro stanovení tělesného složení byla multifrekvenční bioimpedanční analýza (BIA, zařízení B. I. A. 2000-M, Data Input, Germany měřící celkovou impedanci při použití proměnlivé frekvence. Úroveň motorické výkonnosti byla posuzována na základě výsledků základních motorických testů. Z výsledků vyplývá, že systematický trénink realizovaný v prostředí sportovních tříd má evidentně pozitivní dopad, a to nejen v systému přípravy dětí a mládeže pro vrcholový sport, ale především z hlediska vlivu pravidelného pohybového zatížení aplikovaného nad rámec školních osnov na tělesné složení a motorickou výkonnost dospívajícího organismu. Pravidelný trénink tak může z hlediska tělesného složení působit také jako prevence vzniku nadváhy, případně obezity a s tím souvisejících dalších zdravotních rizik v dospělosti. Výsledky této studie mohou být především hodnotnou zpětnou vazbou vedoucí ke zkvalitnění tréninkové přípravy sledovaných jedinců a k obohacení programu lyžařských sportovních t

    2011-07-01

    The Chandra Interactive Plotting System (ChIPS) included in CIAO now allows users to incorporate and manipulate images in their plots. ChIPS uses the Visualization Toolkit (VTK) as a back end to provide basic imaging support, which includes displaying images in pseudo color or RGBA true color, adjusting the translucency of images, and several ways to threshold images. Users also have the ability to enhance them with annotations and place curves and contours directly onto the image. ChIPS imaging support provides a mechanism to adjust the image display resolution as necessary to provide high quality publication ready output. Beyond basic imaging, ChIPS includes the ability to recognize and incorporate WCS metadata into plots. ChIPS accurately calculates the intersections of world coordinate grids and plot axes, ensuring that these elements distort correctly with a tangent plane projection. Multiple image overlays are handled by reprojecting the overlaid images onto the reference image's coordinate system. New zooming and panning functions, and existing limits commands, use the WCS information from the image overlays to update the axes to reflect the new field of view being displayed. Although ChIPS already provides a number of user interactive commands, additional interactive capabilities are being considered for future releases. Enhanced interactive interfaces alongside the ability to script ChIPS in Python provide a more capable and user-friendly system.

Pro zjištění pohybové aktivity a času stráveného sezením byla aplikována standardizovaná administrativní dlouhá verze mezinárodního dotazníku "International Physical Activity Questionnaire". V rámci doplňkové verze dotazníku respondenti poskytli demografické údaje. Pro zjištění vlivu demografi ckých faktorů na pohybovou aktivitu a inaktivitu byla využita binární logistická regrese v programu SPSS 16.0. Doporučení pro intenzivní pohybovou aktivitu splnilo pouze 20,3 % respondentů, pro středně zatěžující pohybovou aktivitu 52,5 % respondentů a pro chůzi 54,4 % respondentů. Z výsledků logistické regrese vyplývá, že větší šanci splnit doporučení pro chůzi mají zaměstnaní lidé a větší šanci splnit doporučení k středně zatěžující pohybové aktivitě mají respondenti ve věku 55–59 let, nekuřáci, se základním vzděláním a žijící v rodinném domku.

Uma dessas relações, foco deste artigo, é a relação entre tamanho de lote de produção e lead time médio. Essa relação é amplamente conhecida na literatura específica sobre teoria de filas, porém o mesmo não acontece na prática em gestão de operações. Este artigo trata deste assunto, objetivando apresentar e comparar o efeito de seis programas de melhoria contínua em variáveis do chão de fábrica (variabilidade da chegada das ordens, variabilidade do processo, taxa de defeito, tempo até a falha, tempo de reparo e tempo de set up na relação tamanho de lote × lead time em um ambiente de máquina única que fabrica múltiplos produtos.

    & Bednarik, 2006. Řízení tak významného zdroje je proto významným úkolem vedení slovinského sportu. CÍLE: Účelem této studie bylo odhalit stávající charakteristiky vůdcovské role dobrovolníků ve slovinských nevládních sportovních organizacích. METODIKA: Výzkum se prováděl na stratifikovaném vzorku 190 vedoucích nevládních sportovních organizací, kteří pracují v různých segmentech slovinského sportu. Měření různých stylů vedení bylo provedeno za pomoci dotazníku o způsobech vedení, zpracovaného na základě situačního modelu vedení Herseyho a Blancharda. VÝSLEDKY: Studie odhalila, že vedoucí sportovních organizací nejčastěji využívají koučování (selling – 42 % případů a podporování (participating – 37 %, zatímco přikazování (telling – 12 % a delegování (delegating – 9 % se používá mnohem méně. Vedoucí přizpůsobují styl vedení aktuálním okolnostem; ovšem nepoužívají vhodný styl vedení vzhledem k úrovni připravenosti svých svěřenců a okolností. Styl vedení nemá přímý dopad na měřené indikátory úspěšnosti sportovních organizací. Zjištění vedou k závěru, že vedoucí slovinských nevládních sportovních organizací obecně přehlížejí význam vůdcovství v tomto kontextu. ZÁVĚRY: Vzhledem k výše uvedeným průměrným výsledkům slovinského sportu lze vyvozovat, že dobrovolná práce ve sportovních organizacích představuje jednu z konkurenčních výhod v naší společnosti. Je proto nezbytné věnovat zvláštní pozornost jejímu rozvojovému potenciálu. Zjištění studie vedou k závěru, že by bylo vhodné ustavit národní strategii dobrovolné práce ve sportu.

    The image shows the new rare Kaon decay experiment at CERN, called NA62. The NA62 experiment is 270 metres long and includes a 120-metre-long vacuum tank, shown here, housing several of the particle detectors. (Note: the experiment axis is a straight line, the curving of the tank is an optical effect of the photo.) Kaons are particles that decay into lighter elementary particles. The kaon decay processes are mostly well known, except for some very rare decay modes. For example, NA62 is investigating a rare decay predicted by the Standard Model in which a kaon decays into one pion and two neutrinos. This process occurs only once every 10 billion decays. The understanding of such ultra-rare decays are of great importance because they test the Standard Model in energy ranges not accessible by direct measurements. They are therefore complementary to the measurements at the LHC. ultra high definition on demand (photolab@cern.ch).

  2. Comparison of Three Isoelectronic Multiple-Well Reaction Systems: OH + CH2O, OH + CH2CH2, and OH + CH2NH.

    Methylenimine (CH2NH) has been predicted to be a product of the atmospheric photo-oxidation of methylamine, but its atmospheric reactions have not been measured. In this paper, we report potential energy surfaces (PESs) and rate constants for OH + CH2NH and its isoelectronic analogues OH + CH2O and OH + CH2CH2, which are more fully understood. The PESs were computed using the BHandHLYP/aug-cc-pVTZ and CCSD(T)/aug-cc-pVTZ levels of theory. Canonical variational transition state theory and Rice-Ramsperger-Kassel-Marcus and master equation modeling were used to calculate temperature- and pressure-dependent rate constants, with particular emphasis on the OH + reactant entrance channels and the effects of prereactive complexes. The computed results are in reasonable agreement with experimental data where they can be compared and also with the results of previous theoretical calculations. The results show that to some extent OH radicals both add to the carbon center double bond in CH2NH and abstract methylene hydrogen atoms, as in the OH + CH2O and OH + CH2CH2 reactions, respectively, but the dominant pathway is abstraction of the hydrogen from N-H. The computed rate constants are suitable for both atmospheric and combustion modeling.

    ChEBI is a database and ontology of chemical entities of biological interest. It is widely used as a source of identifiers to facilitate unambiguous reference to chemical entities within biological models, databases, ontologies and literature. ChEBI contains a wealth of chemical data, covering over 46,500 distinct chemical entities, and related data such as chemical formula, charge, molecular mass, structure, synonyms and links to external databases. Furthermore, ChEBI is an ontology, and thus provides meaningful links between chemical entities. Unlike many other resources, ChEBI is fully human-curated, providing a reliable, non-redundant collection of chemical entities and related data. While ChEBI is supported by a web service for programmatic access and a number of download files, it does not have an API library to facilitate the use of ChEBI and its data in cheminformatics software. To provide this missing functionality, libChEBI, a comprehensive API library for accessing ChEBI data, is introduced. libChEBI is available in Java, Python and MATLAB versions from http://github.com/libChEBI, and provides full programmatic access to all data held within the ChEBI database through a simple and documented API. libChEBI is reliant upon the (automated) download and regular update of flat files that are held locally. As such, libChEBI can be embedded in both on- and off-line software applications. libChEBI allows better support of ChEBI and its data in the development of new cheminformatics software. Covering three key programming languages, it allows for the entirety of the ChEBI database to be accessed easily and quickly through a simple API. All code is open access and freely available.

  6. Faktoring – jedna z hlavních forem financování malých a středních podniků

    2009-12-01

    Full Text Available Faktoring představuje službu, kterou poskytují specializované faktoringové společnosti svým klientům v souvislosti s postoupením nebo se správou pohledávek. Ve své podstatě se jedná o určitý způsob úvěrování, využívaný zejména malými a středními podniky. V praxi existuje několik forem faktoringu v závislosti na tom, do jaké míry přechází na faktora vlastnictví pohledávek a rizika jejich nesplacení. Podle toho se pak faktoringové transakce promítají do účetnictví faktora i klienta. Vzhledem k tomu, že tato služba ani její formy není upravená žádným právním předpisem, postupují faktoringové společnosti často tak, že podmínky ve smlouvách – z důvodu daňových – často zakrývají svojí formou skutečný stav. Uvedený příspěvek základní formy faktoringu vymezuje, popisuje jejich správné účtování včetně daňových dopadů. Factoring is a service, which is offered by specialized factoring agencies to their clients in case of transfer (sale or governance of receivables. In fact, it represents a specific mode of crediting which is mostly preferred by small and medium enterprises. In practices of factoring several forms are differentiated depending on scale of property and risk transfer to the factor. According to these circumstances the factoring transactions are recognized by the factor and the client. The factoring services are not so far regulated by any legal provision. For this reason factoring agencies are proceeding in such a way, that contract conditions – because of tax considerations – hide by their form the substance. The paper describes the factoring forms and interprets their correct recognition on accounting, including tax consequences.

CÍLE: Cílem této studie byla analýza akademického vzdělání a sportovních úspěchů studentů lyžařských škol ve Finsku. METODIKA: Výzkumu se zúčastnilo 49 studentů (15 dívek a 34 chlapců průměrného věku 17 let. Jednalo se o studenty tří lyžařských internátních škol, z nichž dvě byly zaměřené na běh na lyžích a jedna na alpské lyžování. Členy juniorského reprezentačního týmu bylo šedesát procent sjezdových lyžařů, avšak jen šest procent běžců na lyžích. Všichni účastníci vyplnili dotazník o studijních úspěších a sportovních výkonech. VÝSLEDKY: Výsledky ukázaly, že 80 % studentů si prodloužilo středoškolské studium ze tří na čtyři roky. Studenti byli přibližně z 50 % spokojeni se svými akademickými úspěchy. Padesát čtyři procent sjezdových lyžařů a 15 % běžců na lyžích uvedlo, že největších sportovních úspěchů dosáhli v mezinárodních soutěžích. Téměř všichni studenti naznačili, že lyžařská škola jim pomohla zkombinovat sport a vzdělání. Ovšem pouze 40 % sjezdových lyžařů a 62 % běžců na lyžích bylo spokojeno se svými současnými sportovními úspěchy. Sedmdesát tři procent sjezdových lyžařů cítilo, že sportovní aktivity měly negativní vliv na jejich výsledky ve škole. Spokojenost se životem na lyžařských internátních školách byla podpořena sportovními úspěchy, dobrými tréninkovými možnostmi, kvalifikovanými trenéry a pozornými přáteli. ZÁVĚRY: Tyto výsledky podporují koncepci lyžařských škol a vyplývá z nich, že při spojení akademického vzdělání a sportovní kariéry je třeba zvážit mnoho věcí.

    Full Text Available RESUMO A papilomatose é uma doença de natureza crônica e pode causar tumores epiteliais e na mucosa. Não possui predileção por sexo, raça ou idade, mas comumente aparece em animais jovens. As lesões papilares ocorrem principalmente na mucosa bucal, nos lábios, língua e da faringe, além destes, também são encontradas na forma ocular e cutânea. Este estudo teve como objetivo relatar a eficácia da Thuya occidentalis CH12, uma medicação homeopática de uso comum, no tratamento de cães com papilomatose. Os resultados positivos puderam ser vistos, em alguns casos, já na primeira semana do tratamento, em outros, após vinte dias, e o desaparecimento total das lesões, na maioria dos casos, ocorreu com quinze dias. Alicerçada no princípio da similitude, a homeopatia apóia-se na observação experimental de que toda substância capaz de provocar determinados sintomas em uma pessoa sadia, é capaz de curar estes mesmos sintomas em uma pessoa enferma. A Thuya occidentalis provou ser eficiente contra lesões de papilomavírus canina, e apresentou resultados rápidos e com um valor econômico acessível.

  2. Radiative forcing calculations for CH3Cl

    International Nuclear Information System (INIS)

    1994-06-01

    Methyl chloride, CH 3 Cl, is the major natural source of chlorine to the stratosphere. The production of CH 3 Cl is dominated by biological sources from the oceans and biomass burning. Production has a seasonal cycle which couples with the short lifetime of tropospheric CH 3 Cl to produce nonuniform global mixing. As an absorber of infrared radiation, CH 3 Cl is of interest for its potential affect on the tropospheric energy balance as well as for its chemical interactions. In this study, we estimate the radiative forcing and global warming potential (GWP) of CH 3 Cl. Our calculations use an infrared radiative transfer model based on the correlated k-distribution algorithm for band absorption. Global and annual average vertical profiles of temperature and trace gas concentration were assumed. The effects of clouds are modeled using three layers of global and annual average cloud optical properties. A radiative forcing value of 0.0053 W/m 2 ppbv was obtained for CH 3 Cl and is approximately linear in the background abundance. This value is about 2 percent of the forcing of CFC-11 and about 300 times the forcing of CO 2 , on a per molecule basis. The radiative forcing calculation for CH 3 Cl is used to estimate the global warming potential (GWP) of CH 3 Cl. The results give GWPs for CH 3 Cl of the order of 25 at a time of 20 years(CO 2 = 1). This result indicates that CH 3 Cl has the potential to be a major greenhouse gas if significant human related emissions were introduced into the atmosphere

  4. The reaction of fluorine atoms with methanol: yield of CH3O/CH2OH and rate constant of the reactions CH3O + CH3O and CH3O + HO2.

    2018-04-25

    Xenondifluoride, XeF2, has been photolysed in the presence of methanol, CH3OH. Two reaction pathways are possible: F + CH3OH → CH2OH + HF and F + CH3OH → CH3O + HF. Both products, CH2OH and CH3O, will be converted to HO2 in the presence of O2. The rate constants for the reaction of both radicals with O2 differ by more than 3 orders of magnitude, which allows an unequivocal distinction between the two reactions when measuring HO2 concentrations in the presence of different O2 concentrations. The following yields have then been determined from time-resolved HO2 profiles: φCH2OH = (0.497 ± 0.013) and φCH3O = (0.503 ± 0.013). Experiments under low O2 concentrations lead to reaction mixtures containing nearly equal amounts of HO2 (converted from the first reaction) and CH3O (from the second reaction). The subsequent HO2 decays are very sensitive to the rate constants of the reaction between these two radicals and the following rate constants have been obtained: k(CH3O + CH3O) = (7.0 ± 1.4) × 10-11 cm3 s-1 and k(CH3O + HO2) = (1.1 ± 0.2) × 10-10 cm3 s-1. The latter reaction has also been theoretically investigated on the CCSD(T)//M06-2X/aug-cc-pVTZ level of theory and CH3OH + O2 have been identified as the main products. Using μVTST, a virtually pressure independent rate constant of k(CH3O + HO2) = 4.7 × 10-11 cm3 s-1 has been obtained, in good agreement with the experiment.

    The CH-TRU Waste Content Codes (CH-TRUCON) document describes the inventory of the U.S. Department of Energy (DOE) CH-TRU waste within the transportation parameters specified by the Contact-Handled Transuranic Waste Authorized Methods for Payload Control (CH-TRAMPAC). The CH-TRAMPAC defines the allowable payload for the Transuranic Package Transporter-II (TRUPACT-II) and HalfPACT packagings. This document is a catalog of TRUPACT-II and HalfPACT authorized contents and a description of the methods utilized to demonstrate compliance with the CH-TRAMPAC. A summary of currently approved content codes by site is presented in Table 1. The CH-TRAMPAC describes "shipping categories" that are assigned to each payload container. Multiple shipping categories may be assigned to a single content code. A summary of approved content codes and corresponding shipping categories is provided in Table 2, which consists of Tables 2A, 2B, and 2C. Table 2A provides a summary of approved content codes and corresponding shipping categories for the "General Case," which reflects the assumption of a 60-day shipping period as described in the CH-TRAMPAC and Appendix 3.4 of the CH-TRU Payload Appendices. For shipments to be completed within an approximately 1,000-mile radius, a shorter shipping period of 20 days is applicable as described in the CH-TRAMPAC and Appendix 3.5 of the CH-TRU Payload Appendices. For shipments to WIPP from Los Alamos National Laboratory (LANL), Nevada Test Site, and Rocky Flats Environmental Technology Site, a 20-day shipping period is applicable. Table 2B provides a summary of approved content codes and corresponding shipping categories for "Close-Proximity Shipments" (20-day shipping period).

    Science.gov (United States)

    Beischlag, Timothy V; Prefontaine, Gratien G; Hankinson, Oliver

    2018-01-01

    Chromatin immunoprecipitation (ChIP) exploits the specific interactions between DNA and DNA-associated proteins. It can be used to examine a wide range of experimental parameters. A number of proteins bound at the same genomic location can identify a multi-protein chromatin complex where several proteins work together to regulate gene transcription or chromatin configuration. In many instances, this can be achieved using sequential ChIP; or simply, ChIP-re-ChIP. Whether it is for the examination of specific transcriptional or epigenetic regulators, or for the identification of cistromes, the ability to perform a sequential ChIP adds a higher level of power and definition to these analyses. In this chapter, we describe a simple and reliable method for the sequential ChIP assay.

  5. Depicting CH4 fluxes and drivers dynamics

    Since the advancement in CH4 eddy covariance flux measurements, monitoring of CH4 emissions is becoming more widespread. Since CH4 fluxes are not as predictable or as easily interpretable as CO2 fluxes, understanding their emission patterns often still challenging. As these are spatially (ecosystem and latitudinal) and temporal very divers and often event based, a better understanding or interpretation of results is required. An improvement in understanding does also increase the reliability of gap-filling methods as annual greenhouse gas budgets rely on high quality data. There are generalised additive models (Wood 2001) that can easily be applied to sites, models where a relationship between the response variable, in this case CH4 and explanatory variables (drivers) is established. Relevant for CH4flux dynamics are the smoothing function that is applied, where each predictor variable is separated into sections and a polynomial function fitted. On the one hand such models are rarely used as they are difficult to interpret since no parameter values are retuned. On the other hand, such models are very good for prediction and explanatory analysis in estimating the functional nature of a response. Applying such models to CH4 eddy flux data does improve our understanding of the dynamics of CH4 emissions and the respective meteorological drivers. Furthermore, such models combined with tree models (interactions between the explanatory variables), can visualise precise dynamics and easily applied to individual sites. These models are simple tools in understanding of these complex fluxes, as they can include a variety of drivers, and their relevance tested by the model. Model input variables should be as independent as possible (avoiding cross-correlation), avoiding redundant inputs, as models should follow the principle of parsimony of being simple but not too simple.

    We report on the mineralogy, petrography, and O-isotope compositions of ∼60 Ca, Al-rich inclusions (CAIs) incompletely melted during formation of porphyritic chondrules from the CH metal-rich carbonaceous chondrites and Isheyevo (CH/CB). These include (i) relict polymineralic CAIs in porphyritic chondrules, (ii) CAIs surrounded by chondrule-like igneous rims, (iii) igneous pyroxene-rich and Type C-like CAIs, and (iv) plagioclase-rich chondrules with clusters of relict spinel grains. 26Al-26Mg systematics were measured in 10 relict CAIs and 11 CAI-bearing plagioclase-rich chondrules. Based on the mineralogy, the CH CAIs incompletely melted during chondrule formation can be divided into grossite-rich (n = 13), hibonite-rich (n = 11), spinel ± melilite-rich (n = 33; these include plagioclase-rich chondrules with clusters of relict spinel grains) types. Mineralogical observations indicate that these CAIs were mixed with different proportions of ferromagnesian silicates and experienced incomplete melting and gas-melt interaction during chondrule formation. These processes resulted in partial or complete destruction of the CAI Wark-Lovering rims, replacement of melilite by Na-bearing plagioclase, and dissolution and overgrowth of nearly end-member spinel by chromium- and iron-bearing spinel. Only two relict CAIs and two CAI-bearing chondrules show resolvable excess of radiogenic 26Mg; the inferred initial 26Al/27Al ratios are (1.7 ± 1.3) × 10-6, (3.7 ± 3.1) × 10-7, (1.9 ± 0.9) × 10-6 and (4.9 ± 2.6) × 10-6. There is a large range of Δ17O among the CH CAIs incompletely melted during chondrule formation, from ∼-37‰ to ∼-5‰; the unmelted minerals in individual CAIs, however, are isotopically uniform and systematically 16O-enriched relative to the host chondrules and chondrule-like igneous rims, which have Δ17O ranging from ∼-7‰ to ∼+4‰. Most of the CH CAIs incompletely melted during chondrule formation are mineralogically and isotopically

    Recent experiments have shown that it may be possible to use laser-heated high-Z foils to drive new radiation transport (RadTran) experiments in gas fill tubes. These tubes must be pressurized above 1atm and the x-ray source needs to be physically separated from the gas. To achieve this, a grid-supported CH seal is implemented. The grid reduces the total surface area of the gas-seal interaction region lowering the thickness requirements for the CH layer. However, as mesh spacing is reduced, hole closure from wire ablation may reduce the x-ray flux. To optimize the seal design, experiments were performed measuring x-ray transmission through CH layers supported by meshes composed of copper, gold, or stainless steel and using hexagonal or square mesh geometries. The x-ray source was formed by heating a 0.5 μm thick planar gold foil with a 4 ns laser pulse at an intensity of 2 ×1014 W / cm 2. Emission data was collected using an x-ray framing camera and a Dante photodiode array. Experiments show that the CH layers can reach effective temperatures of nearly 100 eV but mesh design significantly affects performance, with a nearly 20 eV difference between the best and worst performing seal targets. This talk will discuss our findings and their impact on future RadTran experiments.

    Full Text Available Fluxes of CH3Br and CH3Cl and their relationship with potential drivers such as sunlight, temperature and soil moisture, were monitored at fortnightly to monthly intervals for more than two years at two contrasting temperate salt marsh sites in Scotland. Manipulation experiments were conducted to further investigate possible links between drivers and fluxes. Fluxes followed both seasonal and diurnal trends with highest fluxes during summer days and lowest (negative fluxes during winter nights. Mean (± 1 sd annually and diurnally-weighted net emissions from the two sites were found to be 300 ± 44 ng m−2 h−1 for CH3Br and 662 ± 266 ng m−2 h−1 for CH3Cl. The fluxes from this work are similar to findings from this and other research groups for salt marshes in cooler, higher latitude climates, but lower than values from salt marshes in the Mediterranean climate of southern California. Statistical analysis generally did not demonstrate a strong link between temperature or sunlight levels and methyl halide fluxes, although it is likely that temperatures have a weak direct influence on emissions, and both certainly have indirect influence via the annual and daily cycles of the vegetation. CH3Cl flux magnitudes from different measurement locations depended on the plant species enclosed whereas such dependency was not discernible for CH3Br fluxes. In 14 out of 18 collars with vegetation CH3Br and CH3Cl net fluxes were significantly positively correlated. The CH3Cl/CH3Br net-emission mass ratio was 2.2, a magnitude lower than mass ratios of global methyl halide budgets (~22 or emissions from tropical rainforests (~60. This is likely due to preference for CH3Br production by the relatively high bromine content in the salt marsh plant material. Extrapolation based solely on data from this study yields salt marsh contributions of 0.5–3.2% and 0.05–0.33%, respectively, of currently-estimated total global production of CH3Br and CH3Cl, but actual

  14. ChIP-chip versus ChIP-seq: Lessons for experimental design and data analysis

    Science.gov (United States)

    2011-01-01

    Background Chromatin immunoprecipitation (ChIP) followed by microarray hybridization (ChIP-chip) or high-throughput sequencing (ChIP-seq) allows genome-wide discovery of protein-DNA interactions such as transcription factor bindings and histone modifications. Previous reports only compared a small number of profiles, and little has been done to compare histone modification profiles generated by the two technologies or to assess the impact of input DNA libraries in ChIP-seq analysis. Here, we performed a systematic analysis of a modENCODE dataset consisting of 31 pairs of ChIP-chip/ChIP-seq profiles of the coactivator CBP, RNA polymerase II (RNA PolII), and six histone modifications across four developmental stages of Drosophila melanogaster. Results Both technologies produce highly reproducible profiles within each platform, ChIP-seq generally produces profiles with a better signal-to-noise ratio, and allows detection of more peaks and narrower peaks. The set of peaks identified by the two technologies can be significantly different, but the extent to which they differ varies depending on the factor and the analysis algorithm. Importantly, we found that there is a significant variation among multiple sequencing profiles of input DNA libraries and that this variation most likely arises from both differences in experimental condition and sequencing depth. We further show that using an inappropriate input DNA profile can impact the average signal profiles around genomic features and peak calling results, highlighting the importance of having high quality input DNA data for normalization in ChIP-seq analysis. Conclusions Our findings highlight the biases present in each of the platforms, show the variability that can arise from both technology and analysis methods, and emphasize the importance of obtaining high quality and deeply sequenced input DNA libraries for ChIP-seq analysis.

    Hsu, K.-J.; Demore, W. B.

    1994-01-01

    Rate constants for the reactions of OH with CH3Cl, CH2Cl2, CHCl3, and CH3Br have been measured by a relative rate technique in which the reaction rate of each compound was compared to that of HFC-152a (CH3CHF2) and (for CH2Cl2) HFC-161 (CH3CH2F). Using absolute rate constants for HFC-152a and HFC-161, which we have determined relative to those for CH4, CH3CCl3, and C2H6, temperature dependent rate constants of both compounds were derived. The derived rate constant for CH3Br is in good agreement with recent absolute measurements. However, for the chloromethanes all the rate constants are lower at atmospheric temperatures than previously reported, especially for CH2Cl2 where the present rate constant is about a factor of 1.6 below the JPL 92-20 value. The new rate constant appears to resolve a discrepancy between the observed atmospheric concentrations and those calculated from the previous rate constant and estimated release rates.

    Mapping the cis-regulatory modules (CRMs) to which bind myogenic transcription factors is an -obligatory step towards understanding gene regulatory networks governing muscle development and function. This can be achieved in silico or by chromatin immunoprecipitation (ChIP) approaches. We have developed a ChIP-enriched in silico targets (ChEST) strategy designed for mapping the CRMs by combining in silico and ChIP methods. ChEST involves a software-assisted prediction of transcription factor (TF) - specific CRMs, which are spotted to produce a computed genomic CRM microarray. In parallel, the in vivo pool of targets of a given TF is isolated by ChIP and used as a probe for hybridization with the array generated. Here we describe ChEST strategy applied to identify direct targets of Myogenic Enhancer Factor, Dmef2 in Drosophila embryos.

    Full Text Available The process of gender identity development in children and youth affects their daily life. With their very existence, transgender children confront the common notions of the majority about “right” boys and girls. There is a persistent pressure in different areas of social life and at schools they visit on preserving the cisnormative way of life. The study is based on a year-long research of transgender children and youth at elementary and secondary schools in Slovakia, with the support of the civic asso- ciation TransFúzia. The research material consists of in-depth interviews with ten children and young people and interviews with the representatives and teachers from three selected secondary schools. The research results suggest that the self-realisation of children in a school environment is influenced by various limits and barriers. These, however, arise not only from the official systemic framework for teaching and the education process in Slovakia, but also from individual notions and approaches by school authorities. The personal stories of seeking their own “self” of transgender children and youth therefore develop in different contexts and under different conditions. They present not only the specific situation of the members of this special minority, but create the image of the daily life of children and youth in a school environment.

The following world stock markets were chosen: US stock market (S&P 500 Total Return index, European stock market (S&P Europe 350 Total Return index and Japan stock market (S&P TOPIX 150 Total Return index. Methodology: The Methodology used in this Paper is based on the quantification of return and risk indicators for different investment horizons. The following investment horizons were chosen: 1 year, 3 years, 5 years and 10 years. The Paper works with quarterly data of selected indices in the period from 1990 to 2010. Indices are used in total return form, i.e. dividends and their reinvesting on the same market are included. Standard deviation is used as the risk indicator and internal rate of return is used as the return indicator. The return-risk profile is quantified as the share of the return indicator and the risk indicator. Findings: Regular investment through the dollar cost averaging method brought substantially better (higher values of the return-risk profile than lump sum investments made during the same period on the same market, mostly over short-term investment horizons (one-year and three-year horizons. Over longer investment horizons, regular investment with the dollar cost averaging method was still bringing better results than the return-risk profile, but given the trend of a growing US and European market, more return could be achieved with lump sum investments than regular investments made over the same period. As the Japanese stock market was stagnating, the gap between the results of the return-risk profile for regular and lump sum investments was closing with growing length of the investment horizon. Conclusions: Regular investments with the dollar cost averaging method are desirable particularly for short-term investment horizons (1-year and 3-year horizons where volatility can be reduced thanks to the right investment timing, but the losses following a slump on the stock market are not so vast as in one-time investments (thanks to cost averaging. On the other hand, the recommendation to invest over the one- or threeyear investment horizon can partially contradict the recommendations for stock markets. Here, the shortest recommended investment horizon is five years. Regular investment with the dollar cost averaging method however significantly reduces the stock market risk also over these investment horizons when compared with one-time investments. As this Paper has however shown, even when the results of the return-risk profile were not so much better for longer investment horizons in regular investments with the dollar cost averaging method than for short-term investment horizons, investments with this method can be still clearly recommended also for these investment horizons – both for growing stock markets, and for long-term stagnating markets.

    Recent studies propose two theories explaining the particular mechanisms of mate choice. Theory of homogamy suggests that individuals prefer partners with personality traits similar to their own. In contrast, theory of complementarity states that people choose mates with opposite personality traits. The main aims of this study were i) to test homogamy and complementarity of dominance in long-term heterosexual and homosexual male couples and ii) to examine whether this similarity predicts high...

    ChIA-PET2 is a versatile and flexible pipeline for analyzing different types of ChIA-PET data from raw sequencing reads to chromatin loops. ChIA-PET2 integrates all steps required for ChIA-PET data analysis, including linker trimming, read alignment, duplicate removal, peak calling and chromatin loop calling. It supports different kinds of ChIA-PET data generated from different ChIA-PET protocols and also provides quality controls for different steps of ChIA-PET analysis. In addition, ChIA-PET2 can use phased genotype data to call allele-specific chromatin interactions. We applied ChIA-PET2 to different ChIA-PET datasets, demonstrating its significantly improved performance as well as its ability to easily process ChIA-PET raw data.

    2009-12-01

    Full Text Available Abstract Background ChIP-Seq and ChIP-PET can potentially be used with any genome for genome wide profiling of protein-DNA interaction sites. Unfortunately, it is probable that most genome assemblies will never reach the quality of the human genome assembly. Therefore, it remains to be determined whether ChIP-Seq and ChIP-PET are practicable with genome sequences other than a few (e.g. human and mouse. Findings Here, we used in silico simulations to assess the impact of completeness or fragmentation of genome assemblies on ChIP-Seq and ChIP-PET data mapping. Conclusions Most currently published genome assemblies are suitable for mapping the short sequence tags produced by ChIP-Seq or ChIP-PET.

    Chromatin ImmunoPrecipitation-sequencing (ChIP-seq) experiments have now become routine in biology for the detection of protein binding sites. In this chapter, we show how hidden Markov models can be used for the analysis of data generated by ChIP-seq experiments. We show how a hidden Markov model can naturally account for spatial dependencies in the ChIP-seq data, how it can be used in the presence of data from multiple ChIP-seq experiments under the same biological condition, and how it naturally accounts for the different IP efficiencies of individual ChIP-seq experiments.

    Full Text Available A molécula de CH3OH é uma das espécies orgânicas mais abundantes no meio interestelar e importante precursor de espécies pré-bióticas. Nesse trabalho estudamos sua sobrevivência em um cenário típico de estrela jovem, na presença de um campo de radiação ultravioleta (UV entre 91.2 – 205 nm. Para isso usamos o código de transferência radiativa RADMC-3D para calcular os perfis de densidade e intensidade média de fótons em toda parte do modelo. Através desses resultados, usamos a seção de choque de destruição do CH3OH na região do ultravioleta para calcular sua taxa de fotodissociação e tempo de meia vida. Concluímos que no interior do disco, a molécula pode sobreviver intacta e ser liberada para a fase gasosa por processos não-térmicos. Porém no envelope, a fotodissociação é predominante, podendo formar espécies como HCOOCH3, HOCH2CHO e CH3CH2OH.

    Full Text Available With the advent of ChIP-seq multiplexing technologies and the subsequent increase in ChIP-seq throughput, the development of working standards for the quality assessment of ChIP-seq studies has received significant attention. The ENCODE consortium’s large scale analysis of transcription factor binding and epigenetic marks as well as concordant work on ChIP-seq by other laboratories has established a new generation of ChIP-seq quality control measures. The use of these metrics alongside common processing steps has however not been evaluated. In this study, we investigate the effects of blacklisting and removal of duplicated reads on established metrics of ChIP-seq quality and show that the interpretation of these metrics is highly dependent on the ChIP-seq preprocessing steps applied. Further to this we perform the first investigation of the use of these metrics for ChIP-exo data and make recommendations for the adaptation of the NSC statistic to allow for the assessment of ChIP-exo efficiency.

    Rate coefficients for the reaction CH3 + O2 = CH3O + O were measured behind reflected shock waves in a series of lean CH4-O2-Ar mixtures using hydroxyl and methyl radical diagnostics. The rate coefficients are well represented by an Arrhenius expression given as k = (1.60(sup +0.67, sub -0.47 ) x 10(exp 13) e(-15813 +/- 587 K/T)/cubic cm.mol.s. This expression, which is valid in the temperature range 1575-1822 K, supports the downward trend in the rate coefficients that has been reported in recent determinations. All measurements to date, including the present study, have been to some extent affected by secondary reactions. The complications due to secondary reactions, choice of thermochemical data, and shock-boundary layer interactions that affect the determination of the rate coefficients are examined.

  15. Bimolecular reaction of CH3 + CO in solid p-H2: infrared absorption of acetyl radical (CH3CO) and CH3-CO complex.

    2014-06-28

    We have recorded infrared spectra of acetyl radical (CH3CO) and CH3-CO complex in solid para-hydrogen (p-H2). Upon irradiation at 248 nm of CH3C(O)Cl/p-H2 matrices, CH3CO was identified as the major product; characteristic intense IR absorption features at 2990.3 (ν9), 2989.1 (ν1), 2915.6 (ν2), 1880.5 (ν3), 1419.9 (ν10), 1323.2 (ν5), 836.6 (ν7), and 468.1 (ν8) cm(-1) were observed. When CD3C(O)Cl was used, lines of CD3CO at 2246.2 (ν9), 2244.0 (ν1), 1866.1 (ν3), 1046.7 (ν5), 1029.7 (ν4), 1027.5 (ν10), 889.1 (ν6), and 723.8 (ν7) cm(-1) appeared. Previous studies characterized only three vibrational modes of CH3CO and one mode of CD3CO in solid Ar. In contrast, upon photolysis of a CH3I/CO/p-H2 matrix with light at 248 nm and subsequent annealing at 5.1 K before re-cooling to 3.2 K, the CH3-CO complex was observed with characteristic IR features at 3165.7, 3164.5, 2150.1, 1397.6, 1396.4, and 613.0 cm(-1). The assignments are based on photolytic behavior, observed deuterium isotopic shifts, and a comparison of observed vibrational wavenumbers and relative IR intensities with those predicted with quantum-chemical calculations. This work clearly indicates that CH3CO can be readily produced from photolysis of CH3C(O)Cl because of the diminished cage effect in solid p-H2 but not from the reaction of CH3 + CO because of the reaction barrier. Even though CH3 has nascent kinetic energy greater than 87 kJ mol(-1) and internal energy ∼42 kJ mol(-1) upon photodissociation of CH3I at 248 nm, its energy was rapidly quenched so that it was unable to overcome the barrier height of ∼27 kJ mol(-1) for the formation of CH3CO from the CH3 + CO reaction; a barrierless channel for formation of a CH3-CO complex was observed instead. This rapid quenching poses a limitation in production of free radicals via bimolecular reactions in p-H2.

    Infrared spectroscopy is commonly used as a tool for identifying the composition of objects in the Solar System and beyond. Using laboratory spectra, optical constants can be calculated and used to create model spectra for comparison to spectra obtained from infrared telescopes. In this study, the optical constants of mixtures of simple organics, including CH4, C2H6, and CH3OH were calculated from 15 to 70 K, in the frequency range of 9000-500 cm(sup -1) (1.1-20 micrometers), at a spectral resolution of 1 cm(sup -1).

    Determining the provenance of naturally occurring methane gases is of major interest to energy companies and atmospheric climate modelers, among others. Bulk isotopic compositions and other geochemical tracers sometimes fail to provide definitive determinations of sources of methane due to complications from mixing and complicated chemical pathways of origin. Recent measurements of doubly-substituted isotopologues of methane, CH2D2 (UCLA) and 13CH3D (UCLA, CalTech, and MIT) have allowed for major improvements in sourcing natural methane gases. Early work has focused on formation temperatures obtained when the relative abundances of both doubly-substituted mass-18 species are consistent with internal equilibrium. When methane gases do not plot on the thermodynamic equilibrium curve in D12CH2D2 vs D13CH3D space, temperatures determined from D13CH3D values alone are usually spurious, even when appearing reasonable. We find that the equilibrium case is actually rare and almost exclusive to thermogenic gases produced at temperatures exceeding 100°C. All other relevant methane production processes appear to generate gases that are not in isotopologue-temperature equilibrium. When gases show departures from equilibrium as determined by the relationship between CH2D2 and 13CH3D abundances, data fall within empirically defined fields representing formation pathways. These fields are thus far consistent between different geological settings and and between lab experiments and natural samples. We have now defined fields for thermogenic gas production, microbial methanogenesis, low temperature abiotic (Sabatier) synthesis and higher temperature FTT synthesis. The majority of our natural methane data can be explained by mixing between end members originating within these production fields. Mixing can appear complex, resulting in both hyper-clumped and anti-clumped isotopologue abundances. In systems where mixtures dominate and end-members are difficult to sample, mixing models

  5. Vibrational Coupling Pathways in the CH Stretch Region of CH_3OH and CH_3OD as Revealed by IR and Ftmw-Ir Spectroscopies

    2011-06-01

    Infrared spectra of jet-cooled CH_3OD and CH_3OH in the CH stretch region are observed by coherence-converted population transfer Fourier transform microwave-infrared (CCPT-FTMW-IR) spectroscopy (E torsional species only) and by slit-jet single resonance spectroscopy (both A and E torsional species, CH_3OH only). Previously, we reported the analysis of ν_3 symmetric CH stretch region (2750-2900 Cm-1), and the present work extends the analysis to higher frequency (2900-3020 Cm-1). The overall observed spectra contain 17 interacting vibrational bands for CH_3OD and 28 for CH_3OH. The signs and magnitudes of the torsional tunneling splittings are deduced for three CH fundamentals (ν_3, ν_9, ν_2) of both molecules and are compared to a model calculation and to ab initio theory. The number and distribution of observed vibrational bands indicate that the CH stretch bright states couple first to doorway states that are binary combinations of bending modes. In the parts of the spectrum where doorway states are present, the observed density of coupled states is comparable to the total density of vibrational states in the molecule, but where there are no doorway states, only the CH stretch fundamentals are observed. A time-dependent interpretation of the present FTMW-IR spectra indicates a fast (˜ 200 fs) initial decay of the bright state followed by second, slower redistribution (˜ 1-3 ps). The qualitative agreement of the present data with the time-dependent experiments of Iwaki and Dlott provides further support for the similarity of the fastest vibrational relaxation processes in the liquid and gas phases.

    Identification of chromatin modifications, e.g., histone acetylation and methylation, among others, is widely carried out by using a chromatin immunoprecipitation (ChIP) strategy. The information obtained with these procedures is useful to gain an overall picture of modifications present in all cells of the population under study. It also serves as a basis to figure out the mechanisms of chromatin organization and gene regulation at the population level. However, the ultimate goal is to understand gene regulation at the level of single chromatin fibers. This requires the identification of chromatin modifications that occur at a given genomic location and within the same chromatin fiber. This is achieved by following a sequential ChIP strategy using two antibodies to distinguish different chromatin modifications. Here, we describe a sequential ChIP protocol (Re-ChIP), paying special attention to the controls needed and the required steps to obtain meaningful and reproducible results. The protocol is developed for young Arabidopsis seedlings but could be adapted to other plant materials.

  10. InChIKey collision resistance: an experimental testing

    Full Text Available Abstract InChIKey is a 27-character compacted (hashed version of InChI which is intended for Internet and database searching/indexing and is based on an SHA-256 hash of the InChI character string. The first block of InChIKey encodes molecular skeleton while the second block represents various kinds of isomerism (stereo, tautomeric, etc.. InChIKey is designed to be a nearly unique substitute for the parent InChI. However, a single InChIKey may occasionally map to two or more InChI strings (collision. The appearance of collision itself does not compromise the signature as collision-free hashing is impossible; the only viable approach is to set and keep a reasonable level of collision resistance which is sufficient for typical applications. We tested, in computational experiments, how well the real-life InChIKey collision resistance corresponds to the theoretical estimates expected by design. For this purpose, we analyzed the statistical characteristics of InChIKey for datasets of variable size in comparison to the theoretical statistical frequencies. For the relatively short second block, an exhaustive direct testing was performed. We computed and compared to theory the numbers of collisions for the stereoisomers of Spongistatin I (using the whole set of 67,108,864 isomers and its subsets. For the longer first block, we generated, using custom-made software, InChIKeys for more than 3 × 1010 chemical structures. The statistical behavior of this block was tested by comparison of experimental and theoretical frequencies for the various four-letter sequences which may appear in the first block body. From the results of our computational experiments we conclude that the observed characteristics of InChIKey collision resistance are in good agreement with theoretical expectations.

    A mobile system was used for continuous ambient measurements of stable CH4 isotopes (12CH4 and 13CH4) and ethane (C2H6). This system was used during a winter mobile campaign to investigate the CH4 isotopic signatures and the C2H6/CH4 ratios of the main anthropogenic sources of CH4 in the Canadian province of Alberta. Individual signatures were derived from δ13CH4 and C2H6 measurements in plumes arriving from identifiable single sources. Methane emissions from beef cattle feedlots (n = 2) and landfill (n = 1) had δ13CH4 signatures of -66.7 ± 2.4‰ and -55.3 ± 0.2‰, respectively. The CH4 emissions associated with the oil or gas industry had distinct δ13CH4 signatures, depending on the formation process. Emissions from oil storage tanks (n = 5) had δ13CH4 signatures ranging from -54.9 ± 2.9‰ to -60.6 ± 0.6‰ and non-detectable C2H6, characteristic of secondary microbial methanogenesis in oil-bearing reservoirs. In contrast, CH4 emissions associated with natural gas facilities (n = 8) had δ13CH4 signatures ranging from -41.7 ± 0.7‰ to -49.7 ± 0.7‰ and C2H6/CH4 molar ratios of 0.10 for raw natural gas to 0.04 for processed/refined natural gas, consistent with thermogenic origins. These isotopic signatures and C2H6/CH4 ratios have been used for source discrimination in the weekly atmospheric measurements of stable CH4 isotopes over a two-month winter period at the Lac La Biche (LLB) measurement station, located in Alberta, approximately 200 km northeast of Edmonton. The average signature of -59.5 ± 1.4‰ observed at LLB is likely associated with transport of air after passing over oil industry sources located south of the station.

  16. Phosphorus addition mitigates N2O and CH4 emissions in N-saturated subtropical forest, SW China

    Directory of Open Access Journals (Sweden)

    L. Yu

    2017-06-01

    Full Text Available Chronically elevated nitrogen (N deposition has led to severe nutrient imbalance in forest soils. Particularly in tropical and subtropical forest ecosystems, increasing N loading has aggravated phosphorus (P limitation of biomass production, and has resulted in elevated emissions of nitrous oxide (N2O and reduced uptake of methane (CH4, both of which are important greenhouse gases. Yet, the interactions of N and P and their effects on greenhouse gas emissions remain elusive. Here, we report N2O and CH4 emissions together with soil N and P data for a period of 18 months following a single P addition (79 kg P ha−1, as NaH2PO4 powder to an N-saturated, Masson pine-dominated forest soil at TieShanPing (TSP, Chongqing, south-western (SW China. We observed a significant decline in both nitrate (NO3− concentrations in soil water (5 and 20 cm depths and in soil N2O emissions, following P application. We hypothesise that enhanced N uptake by plants in response to P addition, resulted in less available NO3− for denitrification. By contrast to most other forest ecosystems, TSP is a net source of CH4. P addition significantly decreased CH4 emissions and turned the soil from a net source into a net sink. Based on our observation and previous studies in South America and China, we believe that P addition relieves N inhibition of CH4 oxidation. Within the 1.5 years after P addition, no significant increase of forest growth was observed and P stimulation of forest N uptake by understorey vegetation remains to be confirmed. Our study indicates that P fertilisation of N-saturated, subtropical forest soils may mitigate N2O and CH4 emissions, in addition to alleviating nutrient imbalances and reducing losses of N through NO3− leaching.

    Context. ALMA is providing us essential information on where certain molecules form. Observing where these molecules emission arises from, the physical conditions of the gas, and how this relates with the presence of other species allows us to understand the formation of many species, and to significantly improve our knowledge of the chemistry that occurs in the space. Aims: We studied the molecular distribution of NaCN around IRC +10216, a molecule detected previously, but whose origin is not clear. High angular resolution maps allow us to model the abundance distribution of this molecule and check suggested formation paths. Methods: We modeled the emission of NaCN assuming local thermal equilibrium (LTE) conditions. These profiles were fitted to azimuthal averaged intensity profiles to obtain an abundance distribution of NaCN. Results: We found that the presence of NaCN seems compatible with the presence of CN, probably as a result of the photodissociation of HCN, in the inner layers of the ejecta of IRC +10216. However, similar as for CH3CN, current photochemical models fail to reproduce this CN reservoir. We also found that the abundance peak of NaCN appears at a radius of 3 × 1015 cm, approximately where the abundance of NaCl, suggested to be the parent species, starts to decay. However, the abundance ratio shows that the NaCl abundance is lower than that obtained for NaCN. We expect that the LTE assumption might result in NaCN abundances higher than the real ones. Updated photochemical models, collisional rates, and reaction rates are essential to determine the possible paths of the NaCN formation.

    As next generation sequencing technologies are becoming more economical, large-scale ChIP-seq studies are enabling the investigation of the roles of transcription factor binding and epigenome on phenotypic variation. Studying such variation requires individual level ChIP-seq experiments. Standard designs for ChIP-seq experiments employ a paired control per ChIP-seq sample. Genomic coverage for control experiments is often sacrificed to increase the resources for ChIP samples. However, the quality of ChIP-enriched regions identifiable from a ChIP-seq experiment depends on the quality and the coverage of the control experiments. Insufficient coverage leads to loss of power in detecting enrichment. We investigate the effect of in silico pooling of control samples within multiple biological replicates, multiple treatment conditions, and multiple cell lines and tissues across multiple datasets with varying levels of genomic coverage. Our computational studies suggest guidelines for performing in silico pooling of control experiments. Using vast amounts of ENCODE data, we show that pairwise correlations between control samples originating from multiple biological replicates, treatments, and cell lines/tissues can be grouped into two classes representing whether or not in silico pooling leads to power gain in detecting enrichment between the ChIP and the control samples. Our findings have important implications for multiplexing samples. PMID:25380244

    Monoclonal antibodies to choline acetyltransferase and a histochemical method for the concurrent demonstration of acetylcholinesterase and horseradish peroxidase were used to investigate the organization of ascending cholinergic pathways in the central nervous system of the rat. The cortical mantle, the amygdaloid complex, the hippocampal formation, the olfactory bulb and the thalamic nuclei receive their cholinergic innervation principally, from cholinergic projection neurons of the basal forebrain and upper brainstem. On the basis of connectivity patterns, we subdivided these cholinergic neurons into six major sectors. The Ch1 and Ch2 sectors are contained within the medial septal nucleus and the vertical limb nucleus of the diagonal band, respectively. They provide the major cholinergic projections of the hippocampus. The Ch3 sector is contained mostly within the lateral portion of the horizontal limb nucleus of the diagonal band and provides the major cholinergic innervation to the olfactory bulb. The Ch4 sector includes cholinergic neurons in the nucleus basalis, and also within parts of the diagonal band nuclei. Neurons of the Ch4 sector provide the major cholinergic innervation of the cortical mantle and the amygdala. The Ch5-Ch6 sectors are contained mostly within the pedunculopontine nucleus of the pontomesencephalic reticular formation (Ch5) and within the laterodorsal tegmental gray of the periventricular area (Ch6). These sectors provide the major cholinergic innervation of the thalamus. The Ch5-Ch6 neurons also provide a minor component of the corticopetal cholinergic innervation. These central cholinergic pathways have been implicated in a variety of behaviors and especially in memory function. It appears that the age-related changes of memory function as well as some of the behavioral disturbances seen in the dementia of Alzheimer's Disease may be related to pathological alterations along central cholinergic pathways.

    Graphical abstract: - Highlights: • A three-phase polymer/liquid/solid (PEBA/PEG/zeolite X) membrane was fabricated. • Nanocrystalline zeolite X was used as filler to stabilize membrane polymeric matrix. • Introducing zeolite to PEBA matrix caused its total free volume to decrease. • A gradual decrease with pressure was observed in CH{sub 4} permeability for the membranes. • In all the experiments, operating pressures varied from 2 to 8 bar. - Abstract: A three-phase polymer/liquid/solid poly(amide-b-ethylene oxide) (PEBA)/polyethylene glycol (PEG)/zeolite X was fabricated and its gas permeability was investigated. CH{sub 4} permeability of neat PEBA, two-phase PEBA/NaX and three-phase PEBA/PEG/NaX were compared for different pressures within the range of 2–8 bar. The fabricated membranes were structurally characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscope (AFM). SEM images showed that the zeolite grain size was homogeneously smaller than 2 μm. They also revealed the dense structures of the membranes and no pores were observed at these magnifications. AFM surface images indicated that the membranes surface roughness increased significantly with increasing zeolite loading. CH{sub 4} permeability for single-, two- and three-phase membranes decreased from 3.13 to 2.81, from 3.96 to 2.31 and from 2.67 to 2.14 barrer, respectively.

    Sequencing data quality and peak alignment efficiency of ChIP-sequencing profiles are directly related to the reliability and reproducibility of NGS experiments. Till now, there is no tool specifically designed for optimal peak alignment estimation and quality-related genomic feature extraction for ChIP-sequencing profiles. We developed open-sourced COPAR, a user-friendly package, to statistically investigate, quantify, and visualize the optimal peak alignment and inherent genomic features using ChIP-seq data from NGS experiments. It provides a versatile perspective for biologists to perform quality-check for high-throughput experiments and optimize their experiment design. The package COPAR can process mapped ChIP-seq read file in BED format and output statistically sound results for multiple high-throughput experiments. Together with three public ChIP-seq data sets verified with the developed package, we have deposited COPAR on GitHub under a GNU GPL license.

    Chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) is a powerful method that identifies protein-DNA binding sites in vivo. Recent studies have illustrated the value of ChIP-seq in studying transcription factor binding in various bacterial species under a variety of growth conditions. These results show that in addition to identifying binding sites, correlation of ChIP-seq data with expression data can reveal important information about bacterial regulons and regulatory networks. In this chapter, we provide an overview of the current state of knowledge about ChIP-seq methodology in bacteria, from sample preparation to raw data analysis. We also describe visualization and various bioinformatic analyses of processed ChIP-seq data. Copyright © 2015 Elsevier Inc. All rights reserved.

    Chromatin immunoprecipitation coupled with massive parallel sequencing (ChIP-seq) is a powerful technology to identify the genome-wide locations of DNA binding proteins such as transcription factors or modified histones. As more and more experimental laboratories are adopting ChIP-seq to unravel the transcriptional and epigenetic regulatory mechanisms, computational analyses of ChIP-seq also become increasingly comprehensive and sophisticated. In this article, we review current computational methodology for ChIP-seq analysis, recommend useful algorithms and workflows, and introduce quality control measures at different analytical steps. We also discuss how ChIP-seq could be integrated with other types of genomic assays, such as gene expression profiling and genome-wide association studies, to provide a more comprehensive view of gene regulatory mechanisms in important physiological and pathological processes.

The bulky P(2)P(3)(tBu) (1) and P(3)P(3)(tBu) (3) ligands are the most sterically encumbered PP(3)-type ligands so far synthesized, and in all cases, only three phosphorus donors are able to bind to the metal center. Complexes RuCl(2)(PhP(2)P(2)(tBu)) (5) and RuCl(2)(P(3)P(3)(tBu)) (6) were characterized by crystallography. Low temperature solution and solid state (31)P{(1)H} NMR were used to demonstrate that the structure of RuCl(2)(P(2)P(3)(tBu)) (4) is probably analogous to that of RuCl(2)(PhP(2)P(2)(tBu)) (5) which had been structurally characterized.

    The main objective of this work was to characterize the new multi-pixel photon counter (MPPC) arrays with a 12 × 12mm2 and a 24 × 24mm2 active area, made using through-silicon via (TSV) technology and with trenches introduced between the cells, in gamma-ray spectrometry with five different scintillators: CsI:Tl, NaI:Tl, LSO/LYSO, BGO, and LaBr3. The results of the study are compared to those obtained previously with the older sample of the 12 × 12mm2 MPPC array made as a monolithic device. TSV MPPC array with the size of 24 × 24mm2 is one of the first commercially available SiPM with such a large active area and with the dead space between channels minimized to only 0.2 mm. Moreover, in these devices, Hamamatsu introduced trenches between cells to reduce cross-talk. Hence excess noise factor (ENF) was also reduced from a value of 1.7 to 1.2 in comparison to the "old" monolithic sample (data for the same overvoltage of 1.3V). Whereby for the new MPPCs, the optimum operating voltage is higher by about 0.6V. In consequence, this higher optimal overvoltage means a higher photon detection efficiency (PDE) and number of photoelectrons, and leads to improved energy resolution. Energy resolution measured for the 662keV full energy peak in a 137 Csγ-source spectrum recorded with 12 × 12mm2 TSV MPPC and two CsI:Tl scintillators (12 × 12 × 12mm3 and 1 × 1 in) equals to 5.8% and 6.8%, respectively. For the "old" MPPC with the same CsI:Tl scintillators energy resolution is equal to 6.4% and 7.1%, respectively. These improved TSV MPPC arrays can be commercially used for scintillation light readout of "large" crystals with a diameter of 1 × 1 in or 2 × 2 in, suitable for gamma spectrometry in a wide range of applications. The combination of new 8 × 8 ch (24 × 24mm2) TSV MPPC and 2 × 2 in NaI:Tl gives an excellent energy resolution below 8%, despite the incomplete match of the scintillator surface to the active area of MPPC and loss of the part of the light.

    2017-10-26

    Chromatin immunoprecipitation sequencing (ChIP-seq) experiments are inexpensive and time-efficient, and result in massive datasets that introduce significant storage and maintenance challenges. To address the resulting Big Data problems, we propose a lossless and lossy compression framework specifically designed for ChIP-seq Wig data, termed ChIPWig. ChIPWig enables random access, summary statistics lookups and it is based on the asymptotic theory of optimal point density design for nonuniform quantizers. We tested the ChIPWig compressor on 10 ChIP-seq datasets generated by the ENCODE consortium. On average, lossless ChIPWig reduced the file sizes to merely 6% of the original, and offered 6-fold compression rate improvement compared to bigWig. The lossy feature further reduced file sizes 2-fold compared to the lossless mode, with little or no effects on peak calling and motif discovery using specialized NarrowPeaks methods. The compression and decompression speed rates are of the order of 0:2 MB/sec using general purpose computers. The source code and binaries are freely available for download athttps://github.com/vidarmehr/ChIPWig-v2, implemented in C ++. milenkov@illinois.edu. Available on the Bioinformatics submission site.

As these horizonts were chosen: 1 year, 3 years, 5 years and 10 years. All Indices are used in total return form, i.e. dividends and their reinvesting on the same market are included. Standard deviation is used as the risk indicator and internal rate of return is used as the return indicator. Scientific aim: The aim of this Paper is to compare and evaluate lump sum and regular investments on world stock markets according to the return-risk profile in the period from 1990 to 2010 for different investment horizons. The following world stock markets were chosen: US stock market (S&P 500 Total Return index, European stock market (S&P Europe 350 Total Return index and Japan stock market (S&P TOPIX 150 Total Return index. Findings: Lump sum investments brought better (higher values of the return-risk profile than regular investment through the value averaging method made during the same period on the same market, mostly over long term investment horizons. Over shorter investment horizons, lump sum was still bringing better results, but risk was always higher than the return.. Conclusions: As this Paper has shown, even when the results of the return-risk profile of regular investment with value averaging method were not better than for lump sum investment strategy, investments with this method can be still clearly recommended as a method reducing the timing risk for long-term growing stock markets.

    Full Text Available Parties are essential components of a political system, since they provide access to the decision-making process for the citizens. In democratic society they have to execute some basic functions (e.g. interest aggregation, articulation and representation. For this they need material and financial resources. In the recent year funding of the parties must deal with growing expensiveness on the one hand, and on the other with bribery and corruption (which can seriously damage citizens’ confidence in the democratic system. Even the most democratic countries have from time to time problem with this unacceptable social phenomena. And it is more important to avoid it in transition countries and in so-called “new democracies” – as central and east European countries, where the democracy is not stabile enough. In this article we focus on the case of Slovakia. We try to outline party finances system and analyse financial resources structure. There are two main models of parties financing, one based on private finances and second based on public resources. Apart from serious defects in laws (still present in Slovak legislation, the main problem of parties financing in Slovakia is growing rate of public party subvention (what can negatively affect parties’ independence on the state and reducing number of party subjects, which participate on it.

  18. CH_{4} production in the deep soil as a source of stem CH_{4} emission in Fagus sylvatica}

    Maier, Martin; Machacova, Katerina; Urban, Otmar; Lang, Friederike

    2017-04-01

    Predicting greenhouse gas (GHG) fluxes on a global scale requires understanding fluxes on the local scale. Understanding GHG processes in soil-plant-atmosphere systems is essential to understand and mitigate GHG fluxes on the local scale. Forests are known to act as carbon sink. Yet, trees at waterlogged sites are known to emit large amounts of CH4, what can offset the positive GHG balance due the CO2 that is sequestered as wood. Generally, upland trees like European beech (Fagus sylvatica L.) are assumed not to emit CH4, and the upland forest soils are regarded as CH4 sinks. Soil-atmosphere fluxes and stem-atmosphere fluxes of CH4 were studied together with soil gas profiles at two upland beech forest sites in Germany and Czech Republic. Soil was a net CH4 sink at both sites. While most trees showed no or low emissions, one beech tree had exorbitant CH4 emissions that were higher than the CH4 sink capacity of the soil. A soil survey showed strong redoximorphic color patterns in the soil adjacent to this tree. Although the soil around the tree was taking up CH4, the soil gas profiles around this tree showed CH4 production at a soil depth >0.3 m. We interpret the coincidence of the production of CH4 in the deep soil below the beech with the large stem emissions as strong hint that there is a transport link between the soil and stem. We think that the root system represents a preferential transport system for CH4 despite the fact that beech roots usually do not have a special gas transport tissue. The observed CH4 stem emissions represent an important CH4 flux in this ecosystem, and, thus, should be considered in future research.

    The long-searched C-H stretches of the fundamental ions CH$^+$ and $^{13}$CH$^+$ have been observed for the first time in the laboratory. For this, the state-dependent attachment of He atoms to these ions at cryogenic temperatures has been exploited to obtain high-resolution rovibrational data. In addition, the lowest rotational transitions of CH$^+$, $^{13}$CH$^+$ and CD$^+$ have been revisited and their rest frequency values improved substantially.

    The cross sections of the different breakup channels of CH4, produced by 4-MeV proton impact, have been measured using the coincidence time-of-flight technique. The relative abundances of the different breakup channels were evaluated for collisions in which the molecule broke into two charged fragments as well as for collisions where only a single charged molecular ion or fragment was produced. These relative abundances are compared to the ones measured for photodissociation, and for electron and proton impact. Only the CH+4 ion survives long enough to be detected as a molecular ion, while the doubly charged CH2+4 ion dissociates rapidly. The most probable final product of the fragmentation of doubly charged methane as formed by fast-proton impact is H++CH+2+H. The abundance of H+m+CH+n (m+nH+3+CH+. Furthermore, some breakup channels of the triply charged CH3+4 have been detected as triple coincidences.

  3. Photodissociation and photoisomerization dynamics of CH2=CHCHO in solution

    By means of time-resolved Fourier transform infrared absorption spectroscopy, we have investigated the 193 nm photodissociation and photoisomerization dynamics of the prototype molecule of α,β-enones, acrolein (CH 2 =CHCHO) in CH 3 CN solution. The primary photolysis channels and absolute branching ratios are determined. The most probable reaction mechanisms are clarified by control experiments monitoring the product yields varied with the triplet quencher addition. The predominant channel is the 1,3-H migration yielding the rearrangement product CH 3 CH=C=O with a branching ratio of 0.78 and the less important channel is the α cleavage of C-H bond yielding radical fragments CH 2 =CHCO+H with a branching ratio of only 0.12. The 1,3-H migration is strongly suggested to correlate with the triplet 3 (ππ * ) state rather than the ground S 0 state and the α cleavage of C-H bond is more likely to proceed in the singlet S 1 1 (nπ * ) state. From the solution experiments we have not only acquired clues clarifying the previous controversial mechanisms, but also explored different photochemistry in solution. Compared to the gas phase photolysis which is dominated by photodissociation channels, the most important channel in solution is the photoisomerization of 1,3-H migration. The reason leading to the different photochemistry in solution is further ascribed to the solvent cage effect.

    Yamashita has described a group of early carbon stars with enhanced lines of barium that resemble the CH stars but have low radial velocities. It is not clear whether they represent a class of stars separate from early R stars. Radial-velocity measurements and abundance analyses are applied in order to clarify the evolutionary status of CH-like stars. Radial-velocity monitoring was performed over a time interval of about 10 years. Abundance analysis was carried out using high-resolution spectra and the method of atmospheric models for three CH-like candidate stars. The radial-velocity monitoring confirmed regular variations for all of the classified CH-like stars, except for two, in support of their binary nature. The calculated orbital parameters are similar to those observed for barium stars in the disk of the Galaxy and their counterparts in the halo, that is, the CH stars. The relatively low luminosity of CH-like stars and the overabundance of s -process elements in the atmospheres are in agreement with a mass-transfer scenario from the secondary—an AGB star in the past. The kinematic data and metallicities support the idea that CH-like stars are thin/thick-disk population objects.

  5. Reviewing ChIPS, The Chandra Imaging and Plotting System

    The Chandra Imaging and Plotting System (ChIPS) is a 2D plotting system designed to allow users to easily create, manipulate, and produce publication quality visualizations. ChIPS has a simple but very powerful interactive interface that allows users to dynamically modify the contents and layout of their plots quickly and efficiently, with the results of any changes being immediately visible. ChIPS allows users to construct their plots fully interactively, and then save the final plot commands as a Python script. This bypasses the need to iteratively edit and rerun the script when developing the plot. Features such as undo and redo commands allow users to easily step backwards and forwards through previous commands, while the ability so save ChIPS sessions in a platform-independent state file allows the session to be restored at any time, even on another machine. Because ChIPS offers a Python interface, users can analyze their data using the broad array of modules offered in Python, and visualize the information in ChIPS at the same time. In this paper we explore the design decisions behind the development of ChIPS and some of the lessons learned along the way.

    In this study the CH4 dissociation probability on Ru(0001) is found for various translational and vibrational energies. The absolute sticking values are determined from King and Wells experiments and carbon uptake curves. The carbon amount is determined from the recombination signal of carbon...... with oxygen obtained after the beam exposure when heating in an oxygen atmosphere. The measured sticking coefficient of CH4 is strongly enhanced both by increasing the translational and the vibrational energy of the CH4 molecule. A model is applied to the data and an estimate of the thermal activation energy...

  11. Evaluating Impacts of CO2 and CH4 Gas Intrusion into an Unconsolidated Aquifer: Fate of As and Cd

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available The sequestration of carbon dioxide (CO2 in deep underground reservoirs has been identified as an important strategy to decrease atmospheric CO2 levels and mitigate global warming, but potential risks on overlying aquifers currently lack a complete evaluation. In addition to CO2, other gases such as methane (CH4 may be present in storage reservoirs. This paper explores for the first time the combined effect of leaking CO2 and CH4 gasses on the fate of major, minor and trace elements in an aquifer overlying a potential sequestration site. Emphasis is placed on the fate of arsenic (As and cadmium (Cd released from the sediments or present as soluble constituents in the leaking brine. Results from macroscopic batch and column experiments show that the presence of CH4 (at a concentration of 1 % in the mixture CO2/CH4 does not have a significant effect on solution pH or the concentrations of most major elements (such as Ca, Ba, and Mg. However, the concentrations of Mn, Mo, Si and Na are inconsistently affected by the presence of CH4 (i.e., in at least one sediment tested in this study. Cd is not released from the sediments and spiked Cd is mostly removed from the aqueous phase most likely via adsorption. The fate of sediment associated As [mainly sorbed arsenite or As(III in minerals] and spiked As [i.e., As5+] is complex. Possible mechanisms that control the As behavior in this system are discussed in this paper. Results are significant for CO2 sequestration risk evaluation and site selection and demonstrate the importance of evaluating reservoir brine and gas stream composition during site selection to ensure the safest site is being chosen.

  12. High Resolution CH4 Emissions and Dissolved CH4 Measurements Elucidate Surface Gas Exchange Processes in Toolik Lake, Arctic Alaska

    Approximately 14% of the Alaskan North Slope is covered in lakes of various sizes and depths. Diffusive carbon emissions (CH4 and CO2) from these lakes offset the tundra sink by ~20 %, but the offset would substantially increase if ebullitive CH4 emissions were also considered. Ultimately, arctic lake CH4 emissions are not insignificant in the global CH4 budget and their contribution is bound to increase due to impacts from climate change. Here we present high resolution CH4 emission data as measured via eddy covariance and a Los Gatos gas analyzer during the ice free period from Toolik Lake, a deep (20 m) Arctic lake located on the Alaskan North Slope, over the last few summers. Emissions are relatively low (Gatos gas analyzer. Thus, having both the flux and the CH4 gradient across the air-water interface measured directly, we can calculate k and investigate the processes influencing CH4 gas exchange in this lake. Preliminary results indicate that there are two regimes in wind speed that impact k - one at low wind speeds up to ~5 m s-1 and another at higher wind speeds (max ~10 m s-1). The differential wind speeds during night and day may compound the effect of convective mixing and cause the diurnal variation in observed fluxes.

    High-accuracy continuous measurements of greenhouse gases (CO2 and CH4) during the BARCA (Balanço Atmosférico Regional de Carbono na Amazônia) phase B campaign in Brazil in May 2009 were accomplished using a newly available analyzer based on the cavity ring-down spectroscopy (CRDS) technique. This analyzer was flown without a drying system or any in-flight calibration gases. Water vapor corrections associated with dilution and pressure-broadening effects for CO2 and CH4 were derived from laboratory experiments employing measurements of water vapor by the CRDS analyzer. Before the campaign, the stability of the analyzer was assessed by laboratory tests under simulated flight conditions. During the campaign, a comparison of CO2 measurements between the CRDS analyzer and a nondispersive infrared (NDIR) analyzer on board the same aircraft showed a mean difference of 0.22±0.09 ppm for all flights over the Amazon rain forest. At the end of the campaign, CO2 concentrations of the synthetic calibration gases used by the NDIR analyzer were determined by the CRDS analyzer. After correcting for the isotope and the pressure-broadening effects that resulted from changes of the composition of synthetic vs. ambient air, and applying those concentrations as calibrated values of the calibration gases to reprocess the CO2 measurements made by the NDIR, the mean difference between the CRDS and the NDIR during BARCA was reduced to 0.05±0.09 ppm, with the mean standard deviation of 0.23±0.05 ppm. The results clearly show that the CRDS is sufficiently stable to be used in flight without drying the air or calibrating in flight and the water corrections are fully adequate for high-accuracy continuous airborne measurements of CO2 and CH4.

    2018-01-01

    Chromatin immunoprecipitation (ChIP) coupled with quantitative PCR (qPCR) has in the last 15 years become a basic mainstream tool in genomic research. Numerous commercially available ChIP kits, qPCR kits, and real-time PCR systems allow for quick and easy analysis of virtually anything chromatin-related as long as there is an available antibody. However, the highly accurate quantitative dimension added by using qPCR to analyze ChIP samples significantly raises the bar in terms of experimental accuracy, appropriate controls, data analysis, and data presentation. This chapter will address these potential pitfalls by providing protocols and procedures that address the difficulties inherent in ChIP-qPCR assays.

    A dither-free stabilization scheme was reported recently1 in which the optical transmission through an absorption cell filled with CH2F2 provided an error signal necessary to stabilize the 214-μm line of CH2F2. Measurements have indicated that this technique is difficult to apply to the 119-μm line of CH3OH due to a lack of contrast in the absorption features of CH3OH over the tuning range of the pump. Efforts to find a nonlasant gas with the required absorption features and to develop a similar technique based on the photoacoustic technique will be described. This research was supported by the Office of Fusion Energy, U.S. DOE, under Contract No. DE-AC05-84OR21400 with Martin Marietta Energy Systems, Inc.

The comparison of the sequences of Siberian cats, non-Siberian cats, and sequences present in the National Center for Biotechnology Information database revealed a considerable number of mutations; some of those detected in the Siberian cat, due to their position in exon regions, could affect the Fel d 1 allergenic properties. Therefore, further investigations are recommended to assess if the identified mutations can be responsible for a reduced-allergen synthesis and can be used as markers for selection of low level allergenic cats.

    There is a growing demand for regional assessments of future climate change and its impacts on society and ecosystems to inform and facilitate appropriate adaptation strategies. The basis for such assessments are consistent and up-to-date climate change scenarios on the local to regional scale. In Switzerland, an important step has been accomplished by the release of the climate scenarios in 2011 ("CH2011"). Since then, new climate model simulations have become available and the scientific understanding has improved. It is hence desirable to update these national scenarios. The new CH2018 scenarios are developed in the framework of the recently founded National Center for Climate Services (NCCS), a network consisting of several federal offices and academic partners. The CH2018 scenarios will build primarily upon the latest Euro-CORDEX regional climate model simulations assuming different pathways of future greenhouse gas concentrations. Compared to CH2011, more emphasis will be put on changes in extremes and in putting the projected changes in the context of observed variability. Results of a recently conducted survey on end-user needs in Switzerland will guide the development process toward the CH2018 scenarios. It ensures that the scenarios are presented and communicated in a user-oriented format and find a wide applicability across different sectors in Switzerland. In the presentation we will show the full methodological setup to generate the CH2018 scenarios and how consistency across the methods and products is maximized. First results on mean changes and selected indices will be presented. In terms of dissemination, the results of the user survey show the necessity to address all different user types of climate scenarios, especially the non-experts. Compared to CH2011, this implies a stronger focus on consulting, condensing complex information and providing tutorials. In the presentation, we will outline our plans on dissemination in order to adequately

    Full Text Available The kinetic isotope effects in the reactions of CH3Cl, 13CH3Cl and CD3Cl with OH radicals and Cl atoms were studied in relative rate experiments at 298±2 K and 1013±10 mbar. The reactions were carried out in a smog chamber using long path FTIR detection and the spectroscopic data analyzed employing a non-linear least squares spectral fitting method using measured high-resolution infrared spectra as well as absorption cross sections from the HITRAN database. The reaction rates of 13CH3Cl and CD3Cl with OH and Cl were determined relative to CH3Cl as: kOH+CH3ClkOH+CH3Cl/kOH+13CH3Cl}kOH+13CH3Cl=1.059±0.008, kOH+CH3ClkOH+CH3Cl/kOH+CD3ClkOH+CD3Cl=3.9±0.4, kCl+CH3ClkCl+CH3Cl/kCl+13CH3ClkCl+13CH3Cl =1.070±0.010 and kCl+CH3ClkCl+CH3Cl/kCl+CD3ClkCl+CD3Cl=4.91±0.07. The uncertainties given are 2σ from the statistical analyses and do not include possible systematic errors. The unexpectedly large 13C kinetic isotope effect in the OH reaction of CH3Cl has important implications for the global emission inventory of CH3Cl.

    We have used the National Ignition Facility (NIF) to conduct absolute equation of state and opacity measurements of plastic CH along the principal Hugoniot at unprecedented pressures, approaching 1 Gbar. A 5 ns long, 1.3 MJ laser pulse at 351 nm, generating a hohlraum drive with 290 eV peak radiation temperature, launches a strong shock wave into a 2.2 mm diameter plastic ball. The induced pressures by the spherical shock wave increase as the shock converges, accessing a range of Hugoniot states in a single experiment. We measure compression from the radiography contrast at the shock front with a powerful Zn He-alpha backlighter. The opacity along the Hugoniot is also deduced, which is essential as it changes significantly from its initial value. We will present results of first NIF experiments where we obtained absolute measurements of Hugoniot states from 120-650 Mbar, which is an order of magnitude greater than previously measured in CH (Cauble et al., PRL 1998). The measured EOS locus is consistent with previous data, and significantly stiffer than the theoretical EOS used for comparison.

    2014-04-16

    A general method for intermolecular allylic C-H alkylation of terminal olefins with tertiary nucleophiles has been accomplished employing palladium(II)/bis(sulfoxide) catalysis. Allylic C-H alkylation furnishes products in good yields (avg. 64%) with excellent regio- and stereoselectivity (>20:1 linear:branched, >20:1 E:Z). For the first time, the olefin scope encompasses unactivated aliphatic olefins as well as activated aromatic/heteroaromatic olefins and 1,4-dienes. The ease of appending allyl moieties onto complex scaffolds is leveraged to enable this mild and selective allylic C-H alkylation to rapidly diversify phenolic natural products. The tertiary nucleophile scope is broad and includes latent functionality for further elaboration (e.g., aliphatic alcohols, α,β-unsaturated esters). The opportunities to effect synthetic streamlining with such general C-H reactivity are illustrated in an allylic C-H alkylation/Diels-Alder reaction cascade: a reactive diene is generated via intermolecular allylic C-H alkylation and approximated to a dienophile contained within the tertiary nucleophile to furnish a common tricyclic core found in the class I galbulimima alkaloids.

Aerogels obtained after supercritical drying have BET surface areas of 649 m2·g–1 (NaYSnS4), 479 m2·g–1 (NaGdSnS4), and 354 m2·g–1 (NaTbSnS4). Electron microscopy and physisorption studies reveal that the new materials have pores in the macro (above 50 nm) and meso (2–50 nm) regions. These aerogels show higher adsorption of toluene vapor over cyclohexane vapor and CO2 over CH4 or H2. The notable adsorption capacity for toluene (NaYSnS4: 1108 mg·g–1; NaGdSnS4: 921 mg·g–1; and NaTbSnS4: 645 mg·g–1) and high selectivity for gases (CO2/H2: 172 and CO2/CH4: 50 for NaYSnS4, CO2/H2: 155 and CO2/CH4: 37 for NaGdSnS4, and CO2/H2: 75 and CO2/CH4: 28 for NaTbSnS4) indicate potential future use of chalcogels in adsorption-based gas or hydrocarbon separation processes.

    The rate coefficients for the reactions of OH radical with CH3Br and CH2Br2 were measured as functions of temperature using the laser photolysis - laser induced fluorescence method. This data was incorporated into a semiempirical model (Solomon et al., 1992) and a 2D model to calculate the steady-state ozone depletion potentials (ODP) and atmospheri lifetimes, tau, with greatly improved accuracy as compared to earlier studies. The calculated ODPs and tau are 0.65 and 1.7 years and 0.17 and 0.41 years for CH3Br and CH2Br2, respectively, using the semiempirical model. These lifetimes agree well with those calculated using a 2D model. This study better quantifies the ODPs and tau of these species which are needed inputs for discussion of possible regulation of human emissions currently under international considerations. 29 refs.

    We consider the general problem of vibrational analysis at nonglobally optimized points on a reduced dimensional reaction surface. We discuss the importance of the use of curvilinear internal coordinates to describe molecular motion and derive a curvilinear projection operator to remove the contribution of nonzero gradients from the Hessian matrix. Our projection scheme is tested in the context of a two-dimensional quantum scattering calculation for the reaction H + CH(4) --> H(2) + CH(3) and its reverse H(2) + CH(3) --> H + CH(4). Using zero-point energies calculated via rectilinear and curvilinear projections we construct two two-dimensional, adiabatically corrected, ab initio reaction surfaces for this system. It is shown that the use of curvilinear coordinates removes unphysical imaginary frequencies observed with rectilinear projection and leads to significantly improved thermal rate constants for both the forward and reverse reactions.

    Full Text Available Introduction: There is a great interest in use of polioximetalates in clinical medicine, primary as antibacterial, antiviral and antitumoral agents. Considering the key role of Na+/ K+- ATPase in normal functioning of most animal cells, as well as pivotal roles in cancer cell migration, the aim of this paper was to examine the influence of new synthesized hexavandates [V6-CH3][Na]2, [V6-NO2][TBA]2, [V6-C3][H]2, [V6-C5d][TBA]2 on Na+/K+- ATPase activity. Material and methods: The enzymatic activity of porcine cerebral cortex Na+/K+- ATPase was followed in both the absence and presence of increasing concentration of [V6-CH3] [Na]2, [V6-NO2][TBA]2, [V6-C3][H]2, [V6-C5d][TBA]2 (within the range 10-8 - 10-3 mol/L. The released Pi, liberated from the enzymatic hydrolysis of ATP, was determined by spectrophotometric method, using Perkin Elmer Lambda 35 UV-VIS spectrophotometer. Results: Investigated compounds inhibit the activity of Na+/K+ ATPase in dose-dependent manner within the investigated range. Obtained results indicate that all investigated compounds inhibit the Na+/K+ ATPase activity, but with different inhibiting power. [V6-NO2] [TBA]2 (IC50 = 1,87 × 10-5 mol/L was the most potent inhibitor of Na+/K+ ATPase, while [V6-C5d][TBA]2 showed the least potent inhibiting power (IC50 = 1,31 × 10-4 mol/L . The results are consistent with previously published concentration-dependent inhibitory effect of polyoxometalates (including polioxovandates on ATPase activity from different model syistems. Conclusion: Based on the results, we can conclude that the examined compounds inhibit Na+/K+- ATPase activity in a dose-dependent manner. Inhibiting power of tested hexavanadates are different, and weaker than inhibiting power of decavanadates (tested earlier on Na+/K+- ATPase activity, which is probably due to differences in charge, size and shape of these polioxometalates. Considering the role of this enzymes in the functioning of healthy cells and the

    Full Text Available V současné hornické praxi patří mezi nejpoužívanější způsoby ochlazování prostorově uzavřených požářišť přirozené ochlazování, ochlazování dusíkem, ochlazování vodou a inertní pěnou a ochlazování recirkulací požárních zplodin. Technologie ochlazování pomocí dusíku představuje dvě varianty - použití kapalného dusíku nebo plynného dusíku v prostoru uzavřených důlních děl. Z technicko-bezpečnostního hlediska je aplikace kapalného dusíku již dnes považována za nevyhovující, naproti tomu aplikace plynného dusíku se jeví jako vysoce bezpečná technologie ochlazování výbuchuvzdorně prostorově uzavřeného požářiště. Další z možností ochlazování požářišť v hlubinných uhelných dolech představuje tzv. přirozené ochlazování, kdy jsou sice ekonomické náklady nulové, ovšem ve srovnání s ochlazovacími procesy vyvolanými aplikací chladících technologií však delší doba potřebná k přirozené refrigeraci požářiště způsobuje finanční ztráty.

    Full Text Available V současném tréninkovém procesu vyspělých družstev ve sportovních hrách jsou preferována tréninková cvičení komplexního charakteru vyžadující zapojení a úzkou spolupráci více hráčů. Předpokladem efektivní manipulace se zatížením je dokonalé poznání používaných cvičení. Cílem provedeného sledování, jehož se zúčastnilo 6 hráčů seniorského volejbalového družstva (průměrný věk 21.2 ± 1.6 let bylo zjistit, jaké zatížení představují dvě ověřované varianty průpravných her a zda bude zatížení při dvou opakováních stejného typu průpravné hry podobné. Porovnání průměrných hodnot srdeční frekvence sledovaného souboru volejbalistů při prvním a druhém provedení ukázalo na věcně i statisticky nevýznamný rozdíl ve velikosti vnitřního zatížení. Rozdíly hodnot sledovaných charakteristik srdeční frekvence u jednotlivců však potvrdily vysokou intraindividuální variabilitu velikosti vnitřního zatížení. Z porovnání průměrných hodnot srdeční frekvence a zatížení cirkulace u dvou typů průpravných her vyplynulo, že z hlediska vnitřního zatížení představovaly odlišné tréninkové stimuly. Z výsledků studie vyplývá, že při manipulaci se zatížením ve volejbalu u herních cvičeních a průpravných her je vhodné považovat údaje o průměrných hodnotách srdeční frekvence pouze za orientační. The key problem of training in sports games is rightfully considered the relation between match performance and training load (Argaj, 2005; Bloomfield, Fricker, & Fitch, 1992; Dobrý & Semiginovský, 1988; Laurenčík, 2006; Reilly & Bangsbo, 1998; Tomajko, 2000. The training process in volleyball must result from the typical demands of match load, the specificities of players’ specializations and their roles in the game system of a team, athletes’ individual specificities and, at the same time, respect the trends of modern

    In this study, we develop three intermolecular potentials for methane (CH4), tetrafluoromethane (CF4), and CH4/CF4 dimers using a novel ab initio method. The ultimate goal is to understand microscopically the phase-separation in CH4/CF4 systems, which takes place in the liquid states near their freezing points. Monte-Carlo (MC) simulations of the pure CH4 system are performed using the ab initio energies to verify the potential. The simulations reproduce quite well the experimentally known liquid densities, the internal energies, the second virial coefficients, and the radial distribution function. The essentially six-dimensional (6D) ab initio potential is then reduced to a one-dimensional (1D) effective potential using the inverse Monte-Carlo technique. This potential, too, successfully reproduces the experimental results. Interestingly, the MC study cannot be extended to the pure CF4 system and the CH4/CF4 mixed system because the two respective ab initio potentials present very rough potential landscapes. This renders the interpolation of energies for the MC simulations and thus the multi-scale approach unreliable. It suggests, however, a possible driving force for the experimentally observed phase separation of the CH4/CF4 system at low temperatures. Furthermore, we carefully study the determination of 1D effective potentials via inverse MC techniques. We argue that to a good approximation the temperature dependence of the 1D potentials can be estimated via reweighting techniques for a fixed temperature.

    Mix and hydro instability growth are key issues in implosions of ignition targets on NIF. The implosions are designed so that the amplitude of perturbations is thought to be determined by initial seeds to the hydrodynamic instabilities, amplified by an instability growth factor. Experiments have indicated that growth factors can be calculated fairly well, but characterizing the initial seeds is an ongoing effort. Several threads of investigation this year have increased our understanding of growth seeded at the CH/DT interface. These include: more detailed characterization of the CH inner surface; possible other seeds, such as density irregularities either from fabrication defects or arising during the implosion; experiments on the Omega laser measuring velocity modulations on shock fronts shortly after breaking out from the CH, which can seed subsequent growth; and the possible significance of non-hydrodynamic effects such as plasma interpenetration or spall-like ejecta upon shock breakout. This presentation describes these developments, the relationships between them, and their implications for ignition target performance.

    Crystallization of Cd[S 2 CN(iPr)CH 2 CH 2 OH] 2 from ethanol yields the coordination polymer [{Cd[S 2 CN(iPr)CH 2 CH 2 OH] 2 }.EtOH] ∞ (1) within 3 h. When the solution is allowed to stand for another hour, the needles begin to dissolve and prisms emerge of the supramolecular isomer (SI), binuclear {Cd[S 2 CN(iPr)CH 2 CH 2 OH] 2 } 2 .2EtOH (2). These have been fully characterized spectroscopically and by X-ray crystallography. Polymeric 1 has 2-fold symmetry and features dithiocarbamate ligands coordinating two octahedral Cd atoms in a μ 2 κ 2 -tridentate mode. Binuclear 2 is centrosymmetric with two ligands being μ 2 κ 2 -tridentate as for 1 but the other two being κ 2 -chelating leading to square pyramidal geometries. The conversion of the kinetic crystallization product, 1, to thermodynamic 2 is irreversible but transformations mediated by recrystallization (ethanol and acetonitrile) to related literature SI species, namely coordination polymer [{Cd[S 2 CN(iPr)CH 2 CH 2 OH] 2 } 3 .MeCN] ∞ and binuclear {Cd[S 2 CN(iPr)CH 2 CH 2 OH] 2 } 2 .2H 2 O.2MeCN, are demonstrated, some of which are reversible. Three other crystallization outcomes are described whereby crystal structures were obtained for the 1:2 co-crystal {Cd[S 2 CN(iPr)CH 2 CH 2 OH] 2 } 2 :2[3-(propan-2-yl)-1,3-oxazolidine-2-thione] (3), the salt co-crystal [iPrNH 2 (CH 2 CH 2 OH)] 4 [SO 4 ] 2 {Cd[S 2 CN(iPr)CH 2 CH 2 OH] 2 } 2 (4) and the salt [iPrNH 2 (CH 2 CH 2 OH)]{Cd[S 2 CN(iPr)CH 2 CH 2 OH] 3 } (5). These arise as a result of decomposition/oxidation of the dithiocarbamate ligands. In each of 3 and 4 the binuclear {Cd[S 2 CN(iPr)CH 2 CH 2 OH] 2 } 2 SI, as in 2, is observed strongly suggesting a thermodynamic preference for this form.

    2008-08-01

    Full Text Available ChIP sequencing (ChIP-seq is a new method for genomewide mapping of protein binding sites on DNA. It has generated much excitement in functional genomics. To score data and determine adequate sequencing depth, both the genomic background and the binding sites must be properly modeled. To develop a computational foundation to tackle these issues, we first performed a study to characterize the observed statistical nature of this new type of high-throughput data. By linking sequence tags into clusters, we show that there are two components to the distribution of tag counts observed in a number of recent experiments: an initial power-law distribution and a subsequent long right tail. Then we develop in silico ChIP-seq, a computational method to simulate the experimental outcome by placing tags onto the genome according to particular assumed distributions for the actual binding sites and for the background genomic sequence. In contrast to current assumptions, our results show that both the background and the binding sites need to have a markedly nonuniform distribution in order to correctly model the observed ChIP-seq data, with, for instance, the background tag counts modeled by a gamma distribution. On the basis of these results, we extend an existing scoring approach by using a more realistic genomic-background model. This enables us to identify transcription-factor binding sites in ChIP-seq data in a statistically rigorous fashion.

    β-Tricalcium phosphate/Chitosan (β-Tcp/Ch) coatings were deposited on 316l stainless steel (316l Ss) substrates by a cathodic electrodeposition technique at different coating compositions. The crystal lattice arrangements were analyzed by X-ray diffraction, and the results indicated that the crystallographic structure of β-Tcp was affected by the inclusion of the chitosan content. The changes in the surface morphology as a function of increasing chitosan in the coatings via scanning electron microscopy and atomic force microscopy showed the root-mean squares hardness of the β-Tcp/Ch coatings decreased by further increasing chitosan percentage. The elastic-plastic characteristics of the coatings were determined by conducting nano indentation test, indicating that the increase if chitosan percentage is directly related to increasing the hardness and elastic modulus of the β-Tcp/Ch coatings. Tribological characterization was performed by scratch test and pin-on-disk test to analyze the changes in the surface wear the β-Tcp/Ch coatings. Finally, the results indicated an improvement in the mechanical and tribological properties of the β-Tcp/Ch coatings as a function of increasing of the chitosan percentage. (Author)

    The stress response of bacterium Cupriavidus metallidurans CH34 into simulated microgravity R. Van Houdt, P. De Boever, I. Coninx, A. Janssen, M.A. Benotmane, N. Leys, and M. Mergeay Expertise group for Molecular and Cellular Biology, Institute for Environment, Health and Safety, Belgian Nuclear Research Centre (SCK•CEN), Boeretang 200, B-2400 Mol, Belgium. We have studied the response of Cupriavidus (formerly Ralstonia) metallidurans CH34 to simulated microgravity by culturing in a Rotating Wall Vessel (RWV) bioreactor. This bioreactor technology generates a unique Low-Shear Modeled Microgravity (LSMMG) environment and is exploited as analogue for in vivo medical and space environments. Cupriavidus and Ralstonia species are relevant model bacteria since they are often isolated from the floor, air and surfaces of spacecraft assembly rooms and not only contaminate the clean rooms but have also been found prior-to-flight on surfaces of space robots such as the Mars Odyssey Orbiter and even in-flight in ISS cooling water and Shuttle drinking water. In addition, C. metallidurans CH34 is also being used in fundamental space flight experiments aimed to gain a better insight in the bacterial adaptation to space. The first objective was to elucidate the stress response of C. metallidurans CH34 grown in LSMMG compared to a normal gravity control. Transcriptomic analysis revealed that a significant part of the heat shock response was induced in LSMMG.

    The reaction pathways and energetics for the reaction of methane with CaO are discussed on the singlet spin state potential energy surface at the B3LYP/6-311+G(2df,2p) and QCISD/6-311++G(3df,3pd)//B3LYP/6-311+G(2df,2p) levels of theory. The reaction of methane with CaO is proposed to proceed in the following reaction pathways: CaO + CH 4 → CaOCH 4 → [TS] → CaOH + CH 3 , CaO + CH 4 → OCaCH 4 → [TS] → HOCaCH 3 → CaOH + CH 3 or [TS] → CaCH 3 OH → Ca + CH 3 OH, and OCaCH 4 → [TS] → HCaOCH 3 → CaOCH 3 + H or [TS] → CaCH 3 OH → Ca + CH 3 OH. The gas-phase methane-methanol conversion by CaO is suggested to proceed via two kinds of important reaction intermediates, HOCaCH 3 and HCaOCH 3 , and the reaction pathway via the hydroxy intermediate (HOCaCH 3 ) is energetically more favorable than the other one via the methoxy intermediate (HCaOCH 3 ). The hydroxy intermediate HOCaCH 3 is predicted to be the energetically most preferred configuration in the reaction of CaO + CH 4 . Meanwhile, these three product channels (CaOH + CH 3 , CaOCH 3 + H and Ca + CH 3 OH) are expected to compete with each other, and the formation of methyl radical is the most preferable pathway energetically. On the other hand, the intermediates HCaOCH 3 and HOCaCH 3 are predicted to be the energetically preferred configuration in the reaction of Ca + CH 3 OH, which is precisely the reverse reaction of methane hydroxylation

    Here, we demonstrate the incorporation of monovalent cation additives into CH3NH3PbI3 perovskite in order to adjust the optical, excitonic, and electrical properties. The possibility of doping was investigated by adding monovalent cation halides with similar ionic radii to Pb 2+ , including Cu + , Na + , and Ag + . A shift in the Fermi level and a remarkable decrease of sub-bandgap optical absorption, along with a lower energetic disorder in the perovskite, was achieved. An order-of-magnitude enhancement in the bulk hole mobility and a significant reduction of transport activation energy within an additive-based perovskite device was attained. The confluence of the aforementioned improved properties in the presence of these cations led to an enhancement in the photovoltaic parameters of the perovskite solar cell. An increase of 70 mV in open circuit voltage for AgI and a 2 mA/cm 2 improvement in photocurrent density for NaI- and CuBr-based solar cells were achieved compared to the pristine device. Our work paves the way for further improvements in the optoelectronic quality of CH3NH3PbI3 perovskite and subsequent devices. It highlights a new avenue for investigations on the role of dopant impurities in crystallization and controls the electronic defect density in perovskite structures.

    Endovascular sealing with the Nellix{sup ®} endoprosthesis (EVAS) is a new technique to treat infrarenal abdominal aortic aneurysms. We describe the use of endovascular sealing in conjunction with chimney stents for the renal arteries (chEVAS) in two patients, one with a refractory type Ia endoleak and an expanding aneurysm, and one with a large juxtarenal aneurysm unsuitable for fenestrated endovascular repair (EVAR). Both aneurysms were successfully excluded. Our report confirms the utility of chEVAS in challenging cases, where suprarenal seal is necessary. We suggest that, due to lack of knowledge on its durability, chEVAS should only been considered when more conventional treatment modalities (open repair and fenestrated EVAR) are deemed difficult or unfeasible.

  11. C-H activation on platinum, a mechanistic study

    Lebrilla, C.B.; Maier, W.F.

    1986-01-01

    C-H activation on heterogeneous Pt catalysts is found to be most facile at low Pt dispersion and surface structure insensitive at dispersions above 10%. Two distinct processes have been identified which lead to the formation of mono- and polydeuterated products, respectively. The ratio of mono-/polydeuteration processes increases with increasing dispersion. Evidence is provided for the formation of π-intermediates as the initiator of polydeuteration. The most facile mechanism of exchange propagation in a single molecule is through a π-allyl-type interconversion. The deuterium in monodeuterated n-hexane is located at the terminal position by high-resolution deuterium NMR. NMR spectroscopy also provides evidence for steric effects which prevent significant H/D exchange at positions close to quaternary centers. C-H activation appears to be sensitive to steric hindrance, the C-H bond energy, and the partial pressure of the substrate

  12. Vibrational transition moments of CH4 from first principles

    2013-09-01

    New nine-dimensional (9D), ab initio electric dipole moment surfaces (DMSs) of methane in its ground electronic state are presented. The DMSs are computed using an explicitly correlated coupled cluster CCSD(T)-F12 method in conjunction with an F12-optimized correlation consistent basis set of the TZ-family. A symmetrized molecular bond representation is used to parameterise these 9D DMSs in terms of sixth-order polynomials. Vibrational transition moments as well as band intensities for a large number of IR-active vibrational bands of 12CH4 are computed by vibrationally averaging the ab initio dipole moment components. The vibrational wavefunctions required for these averages are computed variationally using the program TROVE and a new ‘spectroscopic’ 12CH4 potential energy surface. The new DMSs will be used to produce a hot line list for 12CH4.

    Full Text Available Abstract Background ChIP-Seq is a powerful tool for identifying the interaction between genomic regulators and their bound DNAs, especially for locating transcription factor binding sites. However, high cost and high rate of false discovery of transcription factor binding sites identified from ChIP-Seq data significantly limit its application. Results Here we report a new algorithm, ChIP-PaM, for identifying transcription factor target regions in ChIP-Seq datasets. This algorithm makes full use of a protein-DNA binding pattern by capitalizing on three lines of evidence: 1 the tag count modelling at the peak position, 2 pattern matching of a specific tag count distribution, and 3 motif searching along the genome. A novel data-based two-step eFDR procedure is proposed to integrate the three lines of evidence to determine significantly enriched regions. Our algorithm requires no technical controls and efficiently discriminates falsely enriched regions from regions enriched by true transcription factor (TF binding on the basis of ChIP-Seq data only. An analysis of real genomic data is presented to demonstrate our method. Conclusions In a comparison with other existing methods, we found that our algorithm provides more accurate binding site discovery while maintaining comparable statistical power.

  14. Choice of precipitant and calcination temperature of precursor for synthesis of NiCo2O4 for control of CO-CH4 emissions from CNG vehicles.

    Compressed natural gas (CNG) is most appropriate an alternative of conventional fuel for automobiles. However, emissions of carbon-monoxide and methane from such vehicles adversely affect human health and environment. Consequently, to abate emissions from CNG vehicles, development of highly efficient and inexpensive catalysts is necessary. Thus, the present work attempts to scan the effects of precipitants (Na 2 CO 3 , KOH and urea) for nickel cobaltite (NiCo 2 O 4 ) catalysts prepared by co-precipitation from nitrate solutions and calcined in a lean CO-air mixture at 400°C. The catalysts were used for oxidation of a mixture of CO and CH 4 (1:1). The catalysts were characterized by X-ray diffractometer, Brunauer-Emmett-Teller surface-area, X-ray photoelectron spectroscopy; temperature programmed reduction and Scanning electron microscopy coupled with Energy-Dispersive X-Ray Spectroscopy. The Na 2 CO 3 was adjudged as the best precipitant for production of catalyst, which completely oxidized CO-CH 4 mixture at the lowest temperature (T 100 =350°C). Whereas, for catalyst prepared using urea, T 100 =362°C. On the other hand the conversion of CO-CH 4 mixture over the catalyst synthesized by KOH limited to 97% even beyond 400°C. Further, the effect of higher calcination temperatures of 500 and 600°C was examined for the best catalyst. The total oxidation of the mixture was attained at higher temperatures of 375 and 410°C over catalysts calcined at 500 and 600°C respectively. Thus, the best precipitant established was Na 2 CO 3 and the optimum calcination temperature of 400°C was found to synthesize the NiCo 2 O 4 catalyst for the best performance in CO-CH 4 oxidation.

    We propose a transparent climate debt index incorporating both methane (CH4) and carbon dioxide (CO2) emissions. We develop national historic emissions databases for both greenhouse gases to 2005, justifying 1950 as the starting point for global perspectives. We include CO2 emissions from fossil sources [CO2(f)], as well as, in a separate analysis, land use change and forestry. We calculate the CO2(f) and CH4 remaining in the atmosphere in 2005 from 205 countries using the Intergovernmental Panel on Climate Change's Fourth Assessment Report impulse response functions. We use these calculations to estimate the fraction of remaining global emissions due to each country, which is applied to total radiative forcing in 2005 to determine the combined climate debt from both greenhouse gases in units of milliwatts per square meter per country or microwatts per square meter per person, a metric we term international natural debt (IND). Australia becomes the most indebted large country per capita because of high CH4 emissions, overtaking the United States, which is highest for CO2(f). The differences between the INDs of developing and developed countries decline but remain large. We use IND to assess the relative reduction in IND from choosing between CO2(f) and CH4`control measures and to contrast the imposed versus experienced health impacts from climate change. Based on 2005 emissions, the same hypothetical impact on world 2050 IND could be achieved by decreasing CH4 emissions by 46% as stopping CO2 emissions entirely, but with substantial differences among countries, implying differential optimal strategies. Adding CH4 shifts the basic narrative about differential international accountability for climate change.

  16. Macromolecule simulation and CH4 adsorption mechanism of coal vitrinite

    2017-02-01

    The microscopic mechanism of interactions between CH4 and coal macromolecules is of significant practical and theoretical importance in CBM development and methane storage. Under periodic boundary conditions, the optimal energy configuration of coal vitrinite, which has a higher torsion degree and tighter arrangement, can be determined by the calculation of molecular mechanics (MM) and molecular dynamics (MD), and annealing kinetics simulation based on ultimate analysis, 13C NMR, FT IR and HRTEM. Macromolecular stabilization is primarily due to the van der Waals energy and covalent bond energy, mainly consisting of bond torsion energy and bond angle energy. Using the optimal configuration as the adsorbent, GCMC simulation of vitrinite adsorption of CH4 is conducted. A saturated state is reached after absorbing 17 CH4s per coal vitrinite molecule. CH4 is preferentially adsorbed on the edge, and inclined to gathering around the branched chains of the inner vitrinite sites. Finally, the adsorption parameters are calculated through first principle DFT. The adsorbability order is as follows: aromatic structure> heteroatom rings > oxygen functional groups. The adsorption energy order is as follows: Top graphene. However, the energy of the most preferential location is much lower than that of graphite/graphene. CH4 is more easily absorbed on the surface of vitrinite. Adsorbability varies considerably at different adsorption locations and sites on the surface of vitrinite. Crystal parameter of vitrinite is a = b = c = 15.8 Å and majority of its micropores are blow 15.8 Å, indicating that the vitrinite have the optimum adsorption aperture. It can explain its higher observed adsorption capacities for CH4 compared with graphite/graphene.

    The possible appearance of kilogauss magnetic structure in and above the photosphere of a red giant during helium-shell flash is examined as a mechanism for the outburst of the apparently single star, CH Cyg. Strong magnetic fields created by dynamo action in a temporary connection zone of a red giant core, by virtue of their intrinsic buoyancy, would rise quickly to the stellar surface. It is suggested that if the field is coupled with the large-scale convective structure of the envelope, the energy contained and rate of release would be sufficient to produce the emission features of the spectrum of CH Cyg

  11. Effect of CH4 and O2 variations on rates of CH4 oxidation and stable isotope fractionation in tropical rain forest soils

    Methane-oxidizing bacteria are the primary sink for CH{sub 4} in reduced soils, and account for as much as 90 percent of all CH{sub 4} produced. Methanotrophic bacteria strongly discriminate against the heavy isotopes of carbon, resulting in CH{sub 4} emissions that are significantly more enriched in {sup 13}C than the original source material. Previous studies have used an isotope mass balance approach to quantify CH{sub 4} sources and sinks in the field, based on the assumption that the fractionation factor for CH{sub 4} oxidation is a constant. This study quantifies the effect of systematic variations in CH{sub 4} and O{sub 2} concentrations on rates of CH{sub 4} oxidation and stable isotope fractionation in tropical rain forest soils. Soils were collected from the 0-15 cm depth, and incubated with varying concentrations of CH{sub 4} (100 ppmv, 500 ppmv, 1000 ppmv, and 5000 ppmv) or O{sub 2} (3 percent, 5 percent, 10 percent, and 21 percent). The isotope fractionation factor for CH{sub 4} oxidation was calculated for each incubation using a Rayleigh fractionation model. Rates of CH{sub 4} oxidation varied significantly between CH{sub 4} treatments, with the 100 ppmv CH{sub 4} treatment showing the lowest rate of CH{sub 4} uptake, and the other 3 treatments showing similar rates of CH{sub 4} uptake. Rates of CH{sub 4} oxidation did not vary significantly between the different O{sub 2} treatments. The fractionation factor for CH{sub 4} oxidation varied significantly between the different CH{sub 4} treatments, with the 5000 ppmv CH{sub 4} treatment showing the largest {sup 13}C-enrichment of residual CH{sub 4}. In treatments where CH{sub 4} concentration was not rate-limiting (> 500 ppmv CH{sub 4}), the fractionation factor for CH{sub 4} oxidation was negatively correlated with CH{sub 4} oxidation rate (P < 0.003, r{sup 2} = 0.86). A multiple regression model that included initial CH{sub 4} concentration and CH{sub 4} oxidation rate as independent variables

  12. Correlations between substrate availability, dissolved CH4, and CH4 emissions in an arctic wetland subject to warming and plant removal

    The Arctic is warming which may potentially affect substrate availability, organic matter decomposition, plant growth, and plant species composition. This may lead to changes in the exchange of methane (CH4) and carbon dioxide (CO2) between the soil system and the atmosphere. Yet the correlations...... results on how summer warming and shrub removal affect soil water substrate (acetate, formate, oxalate, and dissolved organic carbon) concentrations as well as dissolved CH4 and CH4 emissions in a fen at Disko Island (West Greenland). The peak in dissolved CH4 followed the peak in acetate concentration...... with removal of the sedge Carex aquatilis ssp. stans which contributed with up to 77% of the CH4 emitted from the ecosystem. By contrast, shrub removal and summer warming did not significantly affect CH4 emissions, possibly due to the treatments impacting CH4 production more than emissions. This implies...

    We present recent progress on the measurement and modeling of CH4 spectroscopy in the NIR region from three separate works in support of the atmospheric remote sensing of CH4 for Jovian and exoplanets. [1] We have studied the H2-broadened CH4 (v2+v3 ,n0 =4545.70 cm-1) in the Octad near 2.3 µm. A series of spectra of CH4 pure and in mixtures with H2 were obtained at several temperatures (100-370 K); these spectra were analyzed using a multispectrum non-linear least squares fitting algorithm adopting a non-Voigt line shape model with full line mixing taken into account. We present the results for H2-pressure broadened widths and shifts along with their temperature dependences for the first time as well as their full line mixing coefficients. We will also discuss the A/E/F rotational symmetry species dependence of the line shape parameters. [2] A new study of 12CH4 spectroscopy was performed for the lower part of the Tetradecad region (5300-5550 cm-1) by analyzing multiple FT-IR spectra of pure CH4 sample recorded at room temperatures at Reims (France) and at 80 K at JPL (USA). Line positions and intensities retrieved from the laboratory spectra were analyzed by the effective Hamiltonian and the effective Dipole moment in terms of irreducible tensor operators adapted to spherical top molecules. Out of the new 5934 measured transitions, quantum assignments were made for 2847 transitions, which represent ~90% of the integrated line intensity in the observed spectra. All the 12CH4 assigned line positions and 2227 selected line intensities were fitted to an RMS standard deviations of 0.0025 cm-1 and 8.6%, respectively. The sum of observed intensities between 5300 and 5550 cm-1 fell within 2% of the predicted value from the ab initio variational calculations. [3] Similarly, for 13CH4 in the 4970-5470 cm-1 region, in total 1387 rovibrational transitions were assigned, pertaining to five cold bands of the Tetradecad up to Jmax=11. Their positions were fitted to an RMS

    Full Text Available The satisfaction of banking clients determines their loyalty and willingness to buy product of the commercial bank. Many of researches and knowledge of banking practices show that there is a big group of dissatisfied customers. The aim of this article was compare the overall level of satisfaction of Czech and Slovak banks’ customers and quantify the most significant factors of satisfaction and dissatisfaction of these customers.Next aim was to define current trends of customers’ satisfaction in relation with the financial performance and the competitiveness of commercial banks. The research about satisfaction of retail customers in Czech and Slovak Republic has been realized through the questionnaire survey. Our research has confirmed that between Czech and Slovak republic exist very similar trends in the area of an overall satisfaction and partial reasons of satisfaction, respectively dissatisfaction of banks’ clients. The most significant reason of customers’ satisfaction is the possibility to use e-banking in both countries. For Czech banking clients is this reason more important than for the Slovak one. The most significant reason of dissatisfaction of banks’ clients is the price policy of banking products and services. The level of dissatisfied clients with this reason is approximately the same in both countries. Customers in both countries feel a low level of acceptance of their financial needs during the sales process. An interesting trend has been observed that satisfied clients use fewer amounts of banks and the value of cross-selling is lower than in the case of dissatisfied clients. A current situation on the Czech and Slovak banking market means, that banks have enough sales opportunities, if they are able to increase a customers’ satisfaction. Purpose of the article: The aim of this article was to quantify and compare the overall satisfaction between Czech and Slovak banks‘customers. Purpose of this article was to define the most important factors of satisfaction and dissatisfaction of banks‘customers and current trends in the area of customers‘satisfaction. Methodology/methods: The research of customers‘satisfaction in Czech and Slovak Republic has been conducted through the questionnaire survey. Set scientific hypothesis has been verified by Pearson chi/square test statistics to determine dependencies in the Pivot table. Methods of descriptive statistics and the weighted average have been used. Scientific aim: Scientific aim was to quantify and compare the overall satisfaction and the most significant reasons of satisfaction and dissatisfaction of Czech and Slovak banks‘clients. Next aim was to examine the impact of clients‘satisfaction on the usage of banking products and banks and to determine the change of the approach of commercial during the crisis. Findings: The overall customers‘satisfaction in Czech Republic and Slovakia is approximately on the same level. The most important reasons of customers‘satisfaction are the possibility to use e-banking in both countries. This trend is more important for Czech banking customers than for Slovak one. The most important dissatisfaction of customers is the price policy of banking products and services. The level of dissatisfied clients with this factor is the same in both countries. Czech and Slovak clients intensively feel the fact that bank just want to sell them their product and earn money and they are not interested in real solution of their financial issue anymore. However, customers of commercial banks still think that banks‘approach has been improved during the crisis. Our research has found out that commercial banks offer their products with low intensity in both countries. Satisfaction of customers significantly determines the amount of used banks. Conclusions: A satisfaction of banks‘customers represents a key parameter of financial performance and competitive ability of a commercial bank. Despite this fact, there exist a big group of dissatisfied clients and many activities of the banks which are not sufficient at all. Our research has been conducted on the sample of representative respondents and has brought some interesting notices which are going to be as the topics of our next researches and are going to be examined more specifically. In the same time, some opportunities to increase the satisfaction of customers which are able to be done in a short period and at minimal cost, has been presented. The very important possibility to increase a customers‘satisfaction is the growth of employees‘satisfaction in the bank.

    This bachelor thesis deals with the problem of electoral fraud in Ukrainian early parliamentary elections in 2014. The incentive for choosing this topic was a negative historical experience with electoral corruption in Ukraine and the assumption that as during the last election to the Verkhovna Rada the situation with fraud would repeat again. The main objective is therefore to examine the process of early election and to answer the question if fraud actually has been noticed during them. The...

    Full Text Available VÝCHODISKA: Analýzou psychologických předpokladů pro vytrvalostní sporty se zabývají sportovní i kliničtí psychologové již několik desítek let. Z vybraných studií provedených u vytrvalostních vícebojařů a vytrvalců obecně (Nideffer, 1995; Nideffer & Bond, 1989; Nideffer & Bond, 1998; Nideffer, 2000; Hátlová, 2000 a další vyplývá, že jedním z nejdůležitějších psychologických předpokladů pro maximální výkon je schopnost koncentrace pozornosti. CÍLE: Cílem bylo zjištění rozdílů v koncentraci pozornosti extrémně vytrvalostně zatěžovaných adolescentů. Výzkum byl realizován na 57 triatlonistech ve věku 15–22 let zařazených do sportovních center mládeže ČR, rozdělených do skupin dle jednotlivých závodních kategorií (15–17 a 18–22. Předpokládali jsme tedy, že je statistický a věcně významný rozdíl v hodnotách naměřených v testech koncentrace pozornosti mezi dorostenci (15–17 let a juniory a K23 (18–22 let. METODIKA: Použili jsme standardizované psychodiagnostické testy (Jiráskův číselný čtverec, Číselný obdélník, Bourdonův test a Disjunkční reakční čas II. Pro porovnání rozdílů výsledků dvou skupin triatlonistů jsme na základě výsledků F-testu použili t-test pro nezávislé výběry s rovností rozptylů. Ověření faktorové validity jsme provedli pomocí konfirmativní faktorové analýzy. Pro vypracování standardů výkonů v jednotlivých testech pro obě věkové kategorie jsme výsledky převedli na standardizované hodnoty (T-body, které názorněji ukazují intra a interindividuální rozdíly vzhledem k určenému modelu – normě. VÝSLEDKY: Výsledky testování ukázaly, že skupina starších triatlonistů vykazuje významně vyšší schopnost koncentrace pozornosti. Rozdíly byly u všech zjišťovaných diagnostik statisticky významné (Jir

  18. Similar foliage area but contrasting foliage biomass between young beech and spruce stands / Porovnateľná plocha avšak kontrastná biomasa asimilačných orgánov medzi mladými porastmi buka a smreka

    Full Text Available Výskum sa zameral na mladé porasty buka lesného (Fagus sylvatica a smreka obyčajného (Picea abies rovnakého veku (12 rokov, veľmi podobných dimenzií stromov, rastúcich na totožnom stanovišti. Na základe odberu vzorníkov celých stromov (všetky časti okrem jemných koreňov sme skonštruovali alometrické vzťahy pre stromové komponenty. Ako nezávislá premenná sa použila hrúbka na báze kmeňa (d0. Modely vyjadrili nielen biomasu konárov, kmeňa, hrubých koreňov a asimilačných orgánov, ale aj plochu asimilačných orgánov a špecifickú listovú plochu (specific leaf area; SLA. Zistili sme, že základné morfologické vlastnosti asimilačných orgánov varírovali pri obidvoch drevinách pozdĺž vertikálneho profilu koruny. V prípade smreka sa zistili odlišné hodnoty plochy ihlíc a SLA medzi jednotlivými ročníkmi ihlíc. Na úrovni stromu mali buky oveľa viac biomasy drevných častí ako smreky, opačná situácia bola pri asimilačných orgánoch. Preto hodnoty podielu medzi biomasou asimilačných orgánov a celkovou biomasou stromu, ako aj pomeru medzi plochou asimilačných orgánov a celkovou biomasou stromu boli výrazne vyššie pri smreku než buku. Na úrovni porastu mala smrečina vyššie hodnoty indexu listovej plochy, t. j. LAI (18,64 m2.m−2 v porovnaní s bučinou (12,77 m2.m−2. Kým biomasa asimilačných orgánov bola 4,6-krát väčšia v smrekovom než v bukovom poraste, biomasa drevných časti bola porovnateľná v obidvoch porastoch. Tieto kontrasty naznačujú výrazne odlišnú rastovú stratégiu, resp. alokáciu biomasy medzi bučinami a smrečinami v mladých štádiách

  19. Subsoil methanogenesis as source of stem CH4 emission in upland forest trees: preferential CH4 transport via the root system?

    Quantifying and understanding green house gas fluxes in natural soil-plant-atmosphere systems are crucial to predicting global climate change. Wetland species or trees at waterlogged sites are known to emit large amounts of CH4. Yet upland forest soils are regarded as CH4 sinks and tree species like upland European beech (Fagus sylvatica, L.) are assumed not to emit CH4. We studied the soil-atmosphere and stem-atmosphere fluxes of CH4, and soil gas profiles at two upland beech forest sites in Central Europe. Soil was a net CH4 sink at both. Unusually there was one beech tree with substantial CH4 emissions that were higher than the CH4 sink of the soil. The soil gas profile at this tree indicated CH4 production at a soil depth >0.3 m, despite the net uptake of CH4 observed at the soil surface adjacent to the tree. Field soil assessment showed strong redoximorphic color patterns in the adjacent soil. We think that there is a transport link between the soil and stem via the root system representing a preferential transport mechanism for CH4 despite the fact that beech roots usually do not bear aerenchyma. The gas transport process , either via dissolved CH4 in the xylem water or in the root gas phase, is not yet clear. The observed CH4 stem emissions represent an important CH4flux in this ecosystem, und thus should be considered in future research.

    Full Text Available Cílem našeho výzkumu bylo zjistit, jakým způsobem slovinská média referují o sportovních akcích. Zvláště nás zajímalo, zda převládají zprávy o sportovcích a zda existují rozdíly ve způsobu, počtu a stylu článků o sportovcích a sportovkyních. Analyzovali jsme dva deníky a porovnávali rozsah, počet článků a fotografie. Články jsme rozřadili do tří skupin: články o sportovcích, články o sportovkyních a články o obojích současně. Podrobněji jsme sledovali jejich styl. Velkou úlohu rovněž hrají fotografie. Srovnávali jsme proto množství, typ, velikost a statický/dynamický charakter fotografií. Výsledky této studie potvrzují některé z předběžných závěrů o tom, že noviny sportovkyním poskytují méně místa, publikují o nich méně článků a věnují jim menší pozornost. Zkoumáním fotografií jsme došli k závěru, že fotografie sportovců jsou lépe umisťovány a že jsou častěji barevné. Sportovkyně jsou zobrazovány tak, aby vynikal jejich tělesný vzhled a nikoli sportovní role. The aim of our research was to establish how Slovene media report on sporting events. We were especially interested if there is a prevalence of reports about male athletes, and if there are differences in manner, amount and style of reporting between the articles about male and female athletes. We analysed two daily newspapers and compared the size, the number of articles, and the photographs. We have classified the articles into three groups; articles about male athletes, articles about female athletes and articles about both. We took a closer look at the style of writing. The photographs also play an important role. Therefore, we also compared the amount, type, size and static/dynamics of photographs. The results of this study confirm some of the preliminary conclusions that the newspapers offer less space, publish less articles and pay less attention to female athletes. By
