    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)

  10. 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.

    (including motivation and by the environment they live in. [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. Rovněž je ovlivňují i specifika

    Fast detection of alpha particles in CR-39 detectors was investigated using a new chemical etchant. 252 Cf and 241 Am sources were used for irradiating samples of CR-39 SSNTDs with fission fragments and alpha particles in air at normal temperature and pressure. A series of experimental chemical etching are carried out using new etching solution (8 ml of 10N NaOH+1 ml CH 3 OH) at 60 °C to detect alpha particle in short time in CR-39 detectors. Suitable analyzing software has been used to analyze experimental data. From fission and alpha track diameters, the value of bulk etching rate is equal to 2.73 μm/h. Both the sensitivity and etching efficiency were found to vary with the amount of methanol in the etching solution. Pure NaOH was used as a control to compare with the result from etching in NaOH with different concentrations of CH 3 OH. The etching efficiency is determined and compared with conventional aqueous solution of 6.25N NaOH at 70 °C for etching time equals 5 h. In this study, the obtained etching efficiency shows a considerable agreement with the previous work. - Highlights: • The value of bulk etching rate is equal to 2.73 μm/h. • Fast detection of alpha particles in CR-39 detectors. • Samples of CR-39 have been irradiated with fission fragments. • Etching efficiency was determined

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.

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. The reaction to high altitude preparation was very good, when in analysed blood components – hematocrit, haemoglobin, erythrocytes, and a medium quantity

    1976-01-01

    The fraction of K and Na atoms which are initially trapped by a clean W(110) surface has been measured as a function of incident energy (0.5 < approximately Esub(i) < approximately 15 eV) at several angles of incidence. At the same time the desorption energies Qsub(i) of the trapped potassium and sodium atoms were measured: Qsub(i) = 2.05 +- 0.02 eV and Qsub(i) = 2.60 +- 0.04 eV respectively. The measured trapping probabilities can be described well by Trillings 'partially screened spherical cap' model, except fos the small angles of incidence. Dynamic trajectory calculations were performed for a particle scattered from a diatomic molecule to explain the screening and the descrepancy at normal incidence. The calculations give good quantitative agreement with the measured trapping probability at small angles both for potassium and sodium atoms and show that simultaneous interaction with two adjacent surface atoms affects the trapping particularly at small angles of incidence.

Cerca de três mil produtos levam o nome de chá, mas na verdade, podem ser considerados como chás somente aqueles que tenham em sua composição a planta Camellia sinensis, que dá origem ao chá verde. Hoje o chá verde, uma das bebidas estimulantes mais consumidas no mundo, é considerado um alimento funcional, que consumido na alimentação cotidiana pode trazer benefícios fisiológicos à saúde, graças aos seus componentes ativos, como os antioxidantes, flavonóides, catequinas, que atuam na prevenção de doenças e em mecanismos específicos do emagrecimento e manutenção do peso corporal. No entanto sua utilização tem sido bastante questionada, motivando a realização de vários estudos para determinar o verdadeiro efeito do chá no organismo e a dose ideal a ser consumida, para que não acarrete prejuízos à saúde, pois ainda não há comprovação científica sobre os benefícios e malefícios que este alimento possa causar em seus usuários. Os hábitos alimentares vão contribuir para o aparecimento ou não de doenças crônicas, com isso a dieta exerce um papel fundamental na prevenção de doenças e para manutenção do peso, aliado a isso à prática de exercícios físicos, obtendo assim um estilo de vida saudável.

  8. EPR study of sodium plutonyl acetate NaPuO2(CH3COO)3 and plutonium thenoyl trifluoroacetonate Pu(TTA)4: self-irradiation effects

    1978-01-01

    High energy radiations are emitted in the radioactive disintegration of plutonium isotopes. These radiations mainly consisting of α-particles interact with the surrounding ligands in the case of plutonium compounds. The ligand molecules undergo electronic excitation, ionization and fragmentation resulting in extensive radiation damage. Electron paramagnetic resonance technique is utilised to indentify and estimate these molecular products formed as a result of self-irradiation in the case of sodium plutonyl acetate, NaPuO 2 (CH 3 COO) 3 , and plutonium thenoyl trifluoroacetonate, Pu(TTA) 4 . The observed EPR spectra are interpreted to be due to acetate and thenoyl trifluoroacetonate radicals with the unpaired electron localized on oxygens of carboxyl group and carbonyl group, respectively. The efficiency parameter, eta, defined as the ratio of the number of paramagnetic species/defects to the total number of radioactive disintegrations has been determined to be 0.83 and 16.9 for the case of the acetate and thenoyl trifluoroacetonate, respectivly.

    Using the method of laser-induced fluorescence, we have measured level to level rate constants for rotational energy transfer (RET) in Na 2 colliding with Xe, Kr, Ar, Ne, He, H 2 , N 2 , and CH 4 . For each target gas we varied the initial rotational quantum number ji-italic over a wide range, typically 4--100, and measured approximately 60 rate constants with an average error of between 6% and 9%. The resulting base of 479 rate constants is used to test several recently proposed fitting laws. The energy corrected sudden scaling law of DePristo et al., when combined with the assumption of a power gap law for the basis rate constants k/sub l/→0, fit with only 3 parameters all of the data for a given target gas with 7%--12% average percentage deviation. Our statistical power gap law worked well and was generally the best law for those data sets with only one value of j/sub i/. The worst fits in all cases considered here were those using the exponential gap law of surprisal theory

O chá preto deixou de inibir a α-amilase e apresentou inibição inalterada para α e β-glicosidases. Tais resultados sugerem que o chá preto pode ser auxiliar em dietas de restrição de carboidratos.Several plants have been considered therapeutic products, including green and black tea, popularly used to control hyperglycemia and obesity. This study aimed to evaluate the inhibitory potential of the enzymes α-amylase, α and β-glycosidases, as well as the content of phenolic compounds in green tea and black tea. The concentrations of phenolic compounds found were 80.8 ± 0.43 mg g-1 in black tea and 32.0 ± 0.12 mg g-1 in green tea. Under the tested conditions of use, green and black tea inhibited the enzyme under study. However, after simulation of the gastric fluid, the inhibitor present in green tea lost its action. Black tea no longer inhibited a-amylase and showed unaltered inhibition for α and β-glycosidases. These results suggest that black tea can be helpful in diets restricting carbohydrates.

    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.

    statistically significant differences. They were: receipt of serve and attack in K1 and K2 for rotation 1, receipt of serve, block and defence for rotation 2, serve and defence for rotation 3, attack in K1 for rotation 6. CONCLUSIONS: These results point to the specific characteristics of individual rotations in this age period, which have to be considered in the organisation of the training process. The results undoubtedly indicate that in the process of the synchronisation of team play, each of the six rotations require specific attention both in the technical and tactical sense. [VÝCHODISKA: Lidé zkoumající volejbal často sledují rozdíly, jež odlišují vyhrávající a prohrávající týmy. Volejbalový zápas totiž probíhá ve dvou celcích (K1 - hra po příjmu podání: podání - příjem podání - příprava útoku - útok; K2 - hra po vlastním podání: podání - blok - obrana - protiútok, a navíc hráči musejí rotovat v souladu s pravidly volejbalové hry. Herní situace v šesti rotacích stejnou měrou neodpovídají K1 a K2, pokud jde o taktické záměry, ani nemají stejnou obtížnost. CÍLE: Studie zkoumala, zda existují statisticky významné rozdíly v jednotlivých fázích volejbalového zápasu mezi vyhrávajícími a prohrávajícími týmy, a to samostatně pro všech šest rotací. Zkoumaly se rozdíly mezi jednotlivými rotacemi mezi vyhrávajícími a prohrávajícími týmy. U rotací se statisticky významnými rozdíly mezi týmy se také zkoumaly ty fáze, jež nejvíce rozhodují o těchto rozdílech. METODIKA: Studie byla prováděna v rámci juniorských mistrovství Evropy ve volejbalu žen. Bylo analyzováno dvacet zápasů, v rámci této analýzy byla použita pětistupňová škála hodnotící úspěšnost hry 98 hráček mladších 18 let. Bylo analyzováno šest fází volejbalového zápasu: podání, příjem podání, útok v rámci K1, útok v rámci K2, blok a obrana (příjem útoku. U každé jednotliv

    Full Text Available Herní charakteristiky elitních tenistů a tenistek na French Open 2005 (Roland Garros byly analyzovány na rozsáhlém základě 894 setů v kategorii mužů a 592 setů v kategorii žen. Navíc se srovnávaly herní charakteristiky jednotlivého setu mezi vítězi a poraženými. Bylo potvrzeno, že u většiny proměnných existují statisticky významné rozdíly mezi vítězi a poraženými, a to jak v kategorii mužů, tak i žen. V kategorii mužů jsou statisticky významné rozdíly u všech proměnných, s výjimkou využití brejkbolu. U žen byly shledány statisticky významné rozdíly u všech proměnných s výjimkou počtu vyhraných es. Na základě těchto zjištění lze učinit závěr, že statisticky významné rozdíly u většiny proměnných určujících herní charakteristiky naznačují existenci určitých měřitelných ukazatelů ve statistice tenisu, kterými se odlišují vítězové od poražených. The game characteristics of elite male and female tennis players at the French Open 2005 (Roland Garros have been analyzed based on a large number of sets, a total of 894 in the category of men and 592 sets in the category of women. In addition, a comparison of game characteristics in an individual set between winners and losers has been made. It was ascertained that there are statistically characteristic differences in most variables between the winners and loser in the category of men as well as in the category of women. In the category of men, there are statistically characteristic differences in all variables except in the break point conversions. In women however, there are statistically characteristic differences in all variables except in the number of won aces. Based on these findings it can be concluded that statistically characteristic differences in the majority of variables, which define game characteristics, indicate that there are certain measurable indicators of tennis statistics, which distinguish

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.

    Highlights: • A new model was established for the phase equilibria of C1–C2–C3–nC4–brine systems. • The model can reproduce of hydrocarbon–brine equilibria to high T&P and salinity. • The model can well predict H 2 O solubility in light hydrocarbon rich phases. - Abstract: A thermodynamic model is presented for the mutual solubility of CH 4 –C 2 H 6 –C 3 H 8 –nC 4 H 10 –brine systems up to high temperature, pressure and salinity. The Peng–Robinson model is used for non-aqueous phase fugacity calculations, and the Pitzer model is used for aqueous phase activity calculations. The model can accurately reproduce the experimental solubilities of CH 4 , C 2 H 6 , C 3 H 8 and nC 4 H 10 in water or NaCl solutions and H 2 O solubility in the non-aqueous phase. The experimental data of mutual solubility for the CH 4 –brine subsystem are sufficient for temperatures exceeding 250 °C, pressures exceeding 1000 bar and NaCl molalities greater than 6 molal. Compared to the CH 4 –brine system, the mutual solubility data of C 2 H 6 –brine, C 3 H 8 –brine and nC 4 H 10 –brine are not sufficient. Based on the comparison with the experimental data of H 2 O solubility in C 2 H 6 -, C 3 H 8 - or nC 4 H 10 -rich phases, the model has an excellent capability for the prediction of H 2 O solubility in hydrocarbon-rich phases, as these experimental data were not used in the modelling. Predictions of hydrocarbon solubility (at temperatures up to 200 °C, pressures up to 1000 bar and NaCl molalities greater than 6 molal) were made for the C 2 H 6 –brine, C 3 H 8 –brine and nC 4 H 10 –brine systems. The predictions suggest that increasing pressure generally increases the hydrocarbon solubility in water or brine, especially in the lower-pressure region. Increasing temperature usually decreases the hydrocarbon solubility at lower temperatures but increases the hydrocarbon solubility at higher temperatures. Increasing water salinity dramatically decreases

    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.

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.

    Full Text Available We have developed a general-purpose block-structured interpretive programming Ianguage. The syntax and semantics of this language called CH are similar to C. CH retains most features of C from the scientific computing point of view. In this paper, the extension of C to CH for numerical computation of real numbers will be described. Metanumbers of −0.0, 0.0, Inf, −Inf, and NaN are introduced in CH. Through these metanumbers, the power of the IEEE 754 arithmetic standard is easily available to the programmer. These metanumbers are extended to commonly used mathematical functions in the spirit of the IEEE 754 standard and ANSI C. The definitions for manipulation of these metanumbers in I/O; arithmetic, relational, and logic operations; and built-in polymorphic mathematical functions are defined. The capabilities of bitwise, assignment, address and indirection, increment and decrement, as well as type conversion operations in ANSI C are extended in CH. In this paper, mainly new linguistic features of CH in comparison to C will be described. Example programs programmed in CH with metanumbers and polymorphic mathematical functions will demonstrate capabilities of CH in scientific computing.

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.

As amostras de chá preto foram as que apresentaram maiores teores de teobromina e cafeína e nenhuma das amostras apresentou quantidades significativas de teofilina.To carry out this study, 10 samples of different kinds and brands of teas were analyzed with the purpose of quantifying simultaneously theobromine, theophylline and caffeine. For this, high performance liquid chromatography (HPLC was used based on ISO 10095 (1992. The conditions were: a reversed phase column (Inertisil ODS-3, 150x4 mm, 5 mm; acetic acid 1% + acetonitrile (95:5, v/v as mobile phase; flow of 1 ml/min and UV-VIS detector set at 273 nm. The results of caffeine obtained by this method were compared with those using a spectrophotometric method according to Schormüller (1970. In the case of black tea, no difference was observed in the caffeine, by both methods. The samples of black tea had the highest amounts of theobromine and caffeine and no sample had a significant amount of theophylline.

    Full Text Available Tea has been considered a medicine and a healthy beverage since ancient times, but recently it has received a great deal of attention because of its antioxidant properties. 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. This paper presents an HPLC analytical methodology development, using column RP-18 and mobile phase composed by water, acetonitrile, methanol, ethyl acetate, glacial acetic acid (89:6:1:3:1 v/v/v/v/v for simultaneous determination and quantification of caffeine (CAF, catechin (C, epicatechin (EC and epigallocatechin gallate (EGCG in samples of Camellia sinensis (green tea grown in Brazil and harvested in spring, in summer and in autumn, in comparison to Brazilian black tea, to samples of Japanese and Chinese green tea and to two standardized dry extracts of green tea. The method has been statistically evaluated and has proved to be adequate to qualitative and quantitative determination of the samples.O chá vem sendo considerado uma bebida saudável e com propriedades medicinais desde tempos bem remotos, mas recentemente tem ganhado grande interesse no meio científico devido a suas atividades como antioxidante.

    The synthesis of ethyl bromide labelled with 14 C, starting from ethanol, has already been studied: 1- by TOLBERT, CHRISTENSON, NAI-HSUAN and SAH; 2- by SIXMA and HENDRIKS. After various blank tests of these two methods, we have finally obtained the best yields by treating the ethanol with a mixture of 40 per cent hydrobromic acid and concentrated sulphuric acid, in the apparatus normally used in the laboratory for the synthesis of CH 3 I slightly modified, so that the current of nitrogen carrying ethyl bromide and hydrobromic acid passes through a sintered glass disc before being bubbled through a solution of NaOH. We describe here the practical process used for the blank test which gave the best yield (91 per cent) and the active synthesis. (author) [fr

    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

  3. Fragmentation characteristics of the unstable [CH3 CO][radical sign] radicals generated by neutralization of [CH3CO]+ cations

    Hop, C. E. C. A.; Holmes, J. L.

    1991-03-01

    The stability and fragmentation characteristics of [CH3 CO][radical sign] radicals, generated by vertical charge exchange between acetyl cations and permanent gases or metal vapours (He, Xe, NO, Cd, Na and K), were examined mass spectrometrically. Two dissociation reactions were observed, the losses of CH[radical sign]3 and H[radical sign]. The H[radical sign] loss reaction, the higher energy dissociation, became of greater importance as the exothermicity of the charge exchange was increased. Based on the analysis of the kinetic energy releases it was concluded that these decompositions arose from the population of two excited states of the [CH3 CO][radical sign] radical.

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 Základním cílem tohoto experimentálního výzkumu bylo zkoumat účinnost rekreačních programů s volejbalovou a plaveckou náplní. Byl prováděn na vzorku 368 studentů mužského pohlaví z Univerzity v Niš, kteří byli rozdělení do 3 podskupin. 115 účastníků bylo přiřazeno do experimentální skupiny, která se věnovala volejbalu, 126 tvořilo experimentální skupinu, která se věnovala plavání a 127 představovalo kontrolní skupinu. Při použití dvou různých programů rekreačního cvičení došlo v průběhu tréninku experimentálních skupin ke zvýšení funkčních schopností, zvláště v případě experimentální skupiny, která se věnovala rekreační volejbalové náplni. U experimentální skupiny, která se věnovala volejbalu, byl stanoven významnější nárůst maximální anaerobní schopnosti a relativního i absolutního maximálního příjmu kyslíku. Využití tohoto typu cvičení při tréninku zaměřeném na jejich vývoj se proto jeví jako opodstatněné. V případě zbývajících dvou experimentálních skupin byl pozorován významný nárůst vitální kapacity plic. Pokud jde o obvodová měření těla a tukové tkáně, byl u experimentální skupiny vůči kontrolní skupině zaznamenán rozdíl ve snížení tukové tkáně a tělesné hmotnosti a zároveň nárůst hodnot při obvodovém měření, což byl důsledek nárůstu svalové tkáně na úkor tkáně tukové. U kontrolní skupiny byl při obvodovém měření zaznamenán nárůst hodnot, a to na úkor tukové tkáně. The basic aim of this experimental research was to study the effectiveness of recreational programs with volleyball and swimming contents.

    Olano, C.; Lemarchand, G.; Sanz, A. J.; Bava, J. A.

    El objetivo principal de este proyecto consiste en el estudio de la distribución y abundancia del CH en nubes interestelares a través de la observación de las líneas hiperfinas del CH en 3,3 GHz. El CH es una molécula de amplia distribución en el espacio interestelar y una de las pocas especies que han sido observadas tanto con técnicas de radio como ópticas. Desde el punto de vista tecnológico se ha desarrollado un cabezal de receptor que permitirá la realización de observaciones polarimétricas en la frecuencia de 3,3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz, y que será instalado en el foco primario de la antena parabólica del IAR. El cabezal del receptor es capaz de detectar señales polarizadas, separando las componentes de polarización circular derecha e izquierda. Para tal fin el cabezal consta de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia más baja (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor además de tener características polarimétricas, podrá ser usado en el continuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

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.

    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.

    Full Text Available No atual ambiente competitivo, a tomada de decisão tem se tornado uma tarefa cada vez mais complicada, envolvendo inúmeras variáveis, e suas relações, nem sempre claramente entendidas. 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. Isto é feito por meio de uma combinação das abordagens System Dynamics (Forrester, 1962 e Factory Physics (Hopp; Spearman, 2008. Dois conjuntos de experimentos são realizados: i Uma melhoria de grandes proporções (50% em cada uma das variáveis separadamente, como aquela que seria obtida por um grande investimento; ii Uma pequena melhoria em todas as variáveis simultaneamente. Os resultados mostraram: (a o efeito positivo de programas de melhoria contínua em variáveis do chão de fábrica no lead time; (b a importância de se conhecer a curva tamanho de lote × lead time e o papel da redução de set up antes de se iniciarem programas de redução de tamanhos de lote; (c que investir em pequenas melhorias em muitas variáveis de forma simultânea é uma política melhor, com relação ao lead time, do que realizar uma grande melhoria em somente uma variável; (d algumas contribuições para um melhor entendimento de modernos paradigmas de gestão da produção, tais como Lean Manufaturing e Quick Response Manufacturing.Many modern manufacturing management approaches present relationships between

    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).

    Patterns of mortality and inhibition of brain and plasma ChE in birds treated with ChE inhibitors were studied in an attempt to determine the validity of using ChE activity as a monitoring and diagnostic technique. Analysis of brain ChE activity proved to be reliable for diagnosing and monitoring effects of selected ChE inhibitors in birds. Brain ChE inhibition exceeding 20% indicated exposure, and inhibition greater than 50% was sufficient for diagnosing cause of death. Individuals that died from dietary exposure to parathion or carbofuran had brain ChE activities below 55% of normal; although individuals could survive with brain ChE activity lower than 50%. Problems associated with collection, storage, and analysis of tissues for ChE activity are discussed.

    & 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.

    We have used a heated 2 cm x 1 mm SiC microtubular (mu tubular) reactor to decompose acetaldehyde: CH3CHO + DELTA --> products. Thermal decomposition is followed at pressures of 75 - 150 Torr and at temperatures up to 1700 K, conditions that correspond to residence times of roughly 50 - 100 mu sec in the mu tubular reactor. The acetaldehyde decomposition products are identified by two independent techniques: VUV photoionization mass spectroscopy (PIMS) and infrared (IR) absorption spectroscopy after isolation in a cryogenic matrix. Besides CH3CHO, we have studied three isotopologues, CH3CDO, CD3CHO, and CD3CDO. We have identified the thermal decomposition products CH3(PIMS), CO (IR, PIMS), H (PIMS), H2 (PIMS), CH2CO (IR, PIMS), CH2=CHOH (IR, PIMS), H2O (IR, PIMS), and HC=CH (IR, PIMS). Plausible evidence has been found to support the idea that there are at least three different thermal decomposition pathways for CH3CHO: Radical decomposition: CH3CHO + DELTA --> CH3 + [HCO] --> CH3 + H + CO Elimination: CH3CHO + DELTA --> H2 + CH2=C=O. Isomerization/elimination: CH3CHO + DELTA --> [CH2=CH-OH] --> HC=CH + H2O. Both PIMS and IR spectroscopy show compelling evidence for the participation of vinylidene, CH2=C:, as an intermediate in the decomposition of vinyl alchohol: CH2=CH-OH + DELTA --> [CH2=C:] + H2O --> HC=CH + H2O.

    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.

    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.

    2015-09-01

    Plasma electrolytic oxidation (PEO) films on AZ31 magnesium alloys were prepared in alkaline silicate electrolytes (base electrolyte) with the addition of different volume concentrations of CH3OH, which was used to adjust the thickness of the vapor sheath. The compositions, morphologies, and thicknesses of ceramic layers formed with different CH3OH concentrations were determined via X-ray diffraction (XRD), energy-dispersive spectroscopy (EDS), and scanning electron microscopy (SEM). Corrosion behavior of the oxide films was evaluated in 3.5 wt.% NaCl solution using potentiodynamic polarization tests. PEO coatings mainly comprised Mg, MgO, and Mg2SiO4. The addition of CH3OH in base electrolytes affected the thickness, pores diameter, and Mg2SiO4 content in the films. The films formed in the electrolyte containing 12% CH3OH exhibited the highest thickness. The coatings formed in the electrolyte containing different concentrations of CH3OH exhibited similar corrosion resistance. The energy consumption of PEO markedly decreased upon the addition of CH3OH to the electrolytes. The result is helpful for energy saving in the PEO process. supported by National Natural Science Foundation of China (No. 21376088), the Project of Production, Education and Research, Guangdong Province and Ministry of Education (Nos. 2012B09100063, 2012A090300015), and Guangzhou Science and Technology Plan Projects of China (No. 2014Y2-00042)

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.

  1. Dynamics of the F(-) + CH3I → HF + CH2I(-) Proton Transfer Reaction.

    Zhang, Jiaxu; Xie, Jing; Hase, William L

    2015-12-17

    Direct chemical dynamics simulations, at collision energies Erel of 0.32 and 1.53 eV, were performed to obtain an atomistic understanding of the F(-) + CH3I reaction dynamics. There is only the F(-) + CH3I → CH3F + I(-) bimolecular nucleophilic substitution SN2 product channel at 0.32 eV. Increasing Erel to 1.53 eV opens the endothermic F(-) + CH3I → HF + CH2I(-) proton transfer reaction, which is less competitive than the SN2 reaction. The simulations reveal proton transfer occurs by two direct atomic-level mechanisms, rebound and stripping, and indirect mechanisms, involving formation of the F(-)···HCH2I complex and the roundabout. For the indirect trajectories all of the CH2I(-) is formed with zero-point energy (ZPE), while for the direct trajectories 50% form CH2I(-) without ZPE. Without a ZPE constraint for CH2I(-), the reaction cross sections for the rebound, stripping, and indirect mechanisms are 0.2 ± 0.1, 1.2 ± 0.4, and 0.7 ± 0.2 Å(2), respectively. Discarding trajectories that do not form CH2I(-) with ZPE reduces the rebound and stripping cross sections to 0.1 ± 0.1 and 0.7 ± 0.5 Å(2). The HF product is formed rotationally and vibrationally unexcited. The average value of J is 2.6 and with histogram binning n = 0. CH2I(-) is formed rotationally excited. The partitioning between CH2I(-) vibration and HF + CH2I(-) relative translation energy depends on the treatment of CH2I(-) ZPE. Without a CH2I(-) ZPE constraint the energy partitioning is primarily to relative translation with little CH2I(-) vibration. With a ZPE constraint, energy partitioning to CH2I(-) rotation, CH2I(-) vibration, and relative translation are statistically the same. The overall F(-) + CH3I rate constant at Erel of both 0.32 and 1.53 eV is in good agreement with experiment and negligibly affected by the treatment of CH2I(-) ZPE, since the SN2 reaction is the major contributor to the total reaction rate constant.

Recent advances in C-H bond activation...... an acetate ion coordinated to Pd. Several of the reported systems rely on benzoquinone for re-oxidation of the active catalyst. The scope for nucleophilic addition in allylic C-H alkylation is currently limited, due to demands on pKa of the nucleophile. This limitation could be due to the pH dependence...

  3. Radiative forcing calculations for CH3Cl

    International Nuclear Information System (INIS)

    Grossman, A.S.; Grant, K.E.; Wuebbles, D.J.

    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

    Positron-annihilation lifetime spectra have been measured for mixtures of CH3Cl and CH3Br in cyclohexane and of CH3Cl in benzene. The ortho-positronium (Ps) yield decreased monotonically from 38% and 43% in cyclohexane and benzene respectively to 11% in pure CH3Cl and 6% in pure CH3Br. The strength......− anions to form Ps. while it forms a bound state with the halides. X−.

    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 visible absorption spectrum of the acetyl radical, CH(3)CO, was measured between 490 and 660 nm at 298 K using cavity ring-down spectroscopy. Gas-phase CH(3)CO radicals were produced using several methods including: (1) 248 nm pulsed laser photolysis of acetone (CH(3)C(O)CH(3)), methyl ethyl ketone (MEK, CH(3)C(O)CH(2)CH(3)), and biacetyl (CH(3)C(O)C(O)CH(3)), (2) Cl + CH(3)C(O)H --> CH(3)C(O) + HCl with Cl atoms produced via pulsed laser photolysis or in a discharge flow tube, and (3) OH + CH(3)C(O)H --> CH(3)CO + H(2)O with two different pulsed laser photolysis sources of OH radicals. The CH(3)CO absorption spectrum was assigned on the basis of the consistency of the spectra obtained from the different CH(3)CO sources and agreement of the measured rate coefficients for the reaction of the absorbing species with O(2) and O(3) with literature values for the CH(3)CO + O(2) + M and CH(3)CO + O(3) reactions. The CH(3)CO absorption spectrum between 490 and 660 nm has a broad peak centered near 535 nm and shows no discernible structure. The absorption cross section of CH(3)CO at 532 nm was measured to be (1.1 +/- 0.2) x 10(-19) cm(2) molecule(-1) (base e).

    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). For shipments implementing the controls specified in the CH-TRAMPAC and Appendix 3.6 of the CH-TRU Payload Appendices, a 10-day shipping period is applicable.

  12. Capture and dissociation in the complex-forming CH + H2 → CH2 + H, CH + H2 reactions.

    González, Miguel; Saracibar, Amaia; Garcia, Ernesto

    2011-02-28

    The rate coefficients for the capture process CH + H(2)→ CH(3) and the reactions CH + H(2)→ CH(2) + H (abstraction), CH + H(2) (exchange) have been calculated in the 200-800 K temperature range, using the quasiclassical trajectory (QCT) method and the most recent global potential energy surface. The reactions, which are of interest in combustion and in astrochemistry, proceed via the formation of long-lived CH(3) collision complexes, and the three H atoms become equivalent. QCT rate coefficients for capture are in quite good agreement with experiments. However, an important zero point energy (ZPE) leakage problem occurs in the QCT calculations for the abstraction, exchange and inelastic exit channels. To account for this issue, a pragmatic but accurate approach has been applied, leading to a good agreement with experimental abstraction rate coefficients. Exchange rate coefficients have also been calculated using this approach. Finally, calculations employing QCT capture/phase space theory (PST) models have been carried out, leading to similar values for the abstraction rate coefficients as the QCT and previous quantum mechanical capture/PST methods. This suggests that QCT capture/PST models are a good alternative to the QCT method for this and similar systems.

    Improvements to the hohlraum for CH implosions have resulted in near-record hot spot pressures, 225 Gbar. Implosion symmetry and laser energy coupling are improved by using a hohlraum that, compared to the previous high gas-fill hohlraum, is longer, larger, at lower gas fill density, and is fielded at zero wavelength separation to minimize cross-beam energy transfer. With a capsule at 90% of its original size in this hohlraum, implosion symmetry changes from oblate to prolate, at 33% cone fraction. Simulations highlight improved inner beam propagation as the cause of this symmetry change. These implosions have produced the highest yield for CH ablators at modest power and energy, i.e., 360 TW and 1.4 MJ. Upcoming experiments focus on continued improvement in shape as well as an increase in implosion velocity. Further, results and future plans on an increase in capsule size to improve margin will also be presented.

    1995-06-01

    Methyl Bromide, CH 3 Br, is the major organobromine species in the lower atmosphere and is a primary source of bromine in the stratosphere. It has a lifetime of 1.3 years. The IR methyl bromide spectra in the atmospheric window region, 7--13μ, was determined using a well tested Coriolis resonance and ell-doubling (and ell-resonance) computational system. A radiative forcing value of 0.00493 W/m 2 /ppbv was obtained for CH 3 Br and is approximately linear in the background abundance. This value is about 2 percent of the forcing of CFC-11 and about 278 times the forcing of C0 2 , on a per molecule basis. The radiative forcing calculation is used to estimate the global warming potential (GWP) of CH 3 Br. The results give GWPs for CH 3 Br of the order of 13 for an integration period of 20 years and 4 for an integration period of 100 years (assuming C0 2 = 1, following IPCC [1994]). While CH 3 Br has a GWP which is approximately 25 percent of the GWP of CH 4 , the current emission rates are too low to cause serious atmospheric greenhouse heating effects at this time

Diversos são os usos populares para essa planta, desde tratamento de dores estomacais, intestinais, antidiarreico, até anticelulite e estética de cabelos oleosos. Essa planta se desenvolve em ambientes insalubres como beira de estrada, e isso pode levar a mudanças no seu aspecto químico e, em consequência disso, mudanças em seus derivados. Este trabalho analisou se ocorreu variação da composição química da planta cultivada na presença ou ausência de estresse ambiental (poluição urbana. Foram pesquisados por meio de cromatografia de camada delgada os seguintes compostos: saponinas, iridoides e proantocianidinas, mono e sesquiterpenos, triterpenos e esteroides, luteolina, polifenóis e alcaloides. Concluiu-se que este fator pode ter contribuído para modificação da composição química de suas folhas, reduzindo a síntese de compostos mais polares e favorecendo a síntese de possíveis leucoantocianidinas para provável proteção. Isso poderá acarretar ao chá alterações em sua propriedade farmacológica e toxicológica.Cymbopogon citratus Stapf, popularly known as lemongrass, is an Indian species.

    The kinetics of thermal electron attachment to methyl thiocyanate (CH3SCN), methyl isothiocyanate (CH3NCS), and ethyl thiocyanate (C2H5SCN) were measured using flowing afterglow-Langmuir probe apparatuses at temperatures between 300 and 1000 K. CH3SCN and C2H5SCN undergo inefficient dissociative attachment to yield primarily SCN- at 300 K (k = 2 × 10-10 cm3 s-1), with increasing efficiency as temperature increases. The increase is well described by activation energies of 0.17 eV (CH3SCN) and 0.14 eV (C2H5SCN). CN- product is formed at product but at a rate at 300 K that is below our detection threshold (k differentiating the two mechanisms. The kinetic modeling reproduces the CH3NCS data only if dissociation through the transient anion is considered.

  3. Studies of soft x-ray transmission through grid supported CH layers

    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 Purpose of the article: The focus of this article are lump sum and regular investments (dollar cost averaging method on selected world stock markets in the period from 1990 to 2010 for different investment horizons. Scientific aim: The aim of this Paper is to compare and evaluate lump sum and regular investments (dollar cost averaging method on important 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. 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.

    2010-01-01

    A new set of laboratory experimental frequencies for the J = 1-0 rotational transition of 12 CH + , 13 CH + , and 12 CD + are obtained by using a liquid nitrogen cooled extended negative glow discharge in a gas mixture of CH 4 and He. These frequencies are found to be significantly different from those reported previously. The unexpectedly large Zeeman effect and the spin-rotation hyperfine interaction for a 1 Σ molecule are observed. The Zeeman effect and the hyperfine interaction appear to be distinctively different for each isotopic species. Theoretical considerations reveal the isotopic dependence of the magnitudes of these effects, and they also provide strong evidence for the identifications.

  4. Ab Initio Chemical Kinetics for the CH3 + O((3)P) Reaction and Related Isomerization-Decomposition of CH3O and CH2OH Radicals.

    2015-07-16

    The kinetics and mechanism of the CH3 + O reaction and related isomerization-decomposition of CH3O and CH2OH radicals have been studied by ab initio molecular orbital theory based on the CCSD(T)/aug-cc-pVTZ//CCSD/aug-cc-pVTZ, CCSD/aug-cc-pVDZ, and G2M//B3LYP/6-311+G(3df,2p) levels of theory. The predicted potential energy surface of the CH3 + O reaction shows that the CHO + H2 products can be directly generated from CH3O by the TS3 → LM1 → TS7 → LM2 → TS4 path, in which both LM1 and LM2 are very loose and TS7 is roaming-like. The result for the CH2O + H reaction shows that there are three low-energy barrier processes including CH2O + H → CHO + H2 via H-abstraction and CH2O + H → CH2OH and CH2O + H → CH3O by addition reactions. The predicted enthalpies of formation of the CH2OH and CH3O radicals at 0 K are in good agreement with available experimental data. Furthermore, the rate constants for the forward and some key reverse reactions have been predicted at 200-3000 K under various pressures. Based on the new reaction pathway for CH3 + O, the rate constants for the CH2O + H and CHO + H2 reactions were predicted with the microcanonical variational transition-state/Rice-Ramsperger-Kassel-Marcus (VTST/RRKM) theory. The predicted total and individual product branching ratios (i.e., CO versus CH2O) are in good agreement with experimental data. The rate constant for the hydrogen abstraction reaction of CH2O + H has been calculated by the canonical variational transition-state theory with quantum tunneling and small-curvature corrections to be k(CH2O + H → CHO + H2) = 2.28 × 10(-19) T(2.65) exp(-766.5/T) cm(3) molecule(-1) s(-1) for the 200-3000 K temperature range. The rate constants for the addition giving CH3O and CH2OH and the decomposition of the two radicals have been calculated by the microcanonical RRKM theory with the time-dependent master equation solution of the multiple quantum well system in the 200-3000 K temperature range at 1 Torr to

    Full Text Available Hodnocení rizika je nedílnou součástí posouzení investičního projektu. Podcenění rizika může vést k chybným závěrům s negativními dopady na ekonomiku projektu. S ohledem na výši investic a hledisko času v podmínkách těžebního podniku, nabývá problematika rizika na významu. Z hodnocení stávajících praktických zkušeností vyplývá, že manažeři těžebních podniků přistupují ke stanovení rizika častěji na bázi intuice, než s využitím exaktních metod. Článek se věnuje vlastnímu stanovení rizika, jehož postup naznačuje na modelovém příkladu posuzování kontinuální a diskontinuální alternativy exploatace sypkých skrývkových hmot při velkokapacitní těžbě uhlí probíhající na jámových lomech.

  8. Tropospheric radiative forcing of CH4

    1994-04-01

    We have evaluated the tropospheric radiative forcing of CH 4 in the 0-3000 cm -1 wavenumber range and compared this with prior published calculations. The atmospheric test cases involved perturbed methane scenarios in both a McClatchey mid latitude, summer, clear sky approximation, model atmosphere, as well as a globally and seasonally averaged model atmosphere containing a representative cloud distribution. The scenarios involved pure CH 4 radiative forcing and CH 4 plus a mixture of H 2 O, CO 2 , O 3 , and N 2 O. The IR radiative forcing was calculated using a correlated k-distribution transmission model. The major purposes of this paper are to first, use the correlated k-distribution model to calculate the tropospheric radiative forcing for CH 4 , as the only radiatively active gas, and in a mixture with H 2 O, CO 2 , O 3 , and N 2 O, for a McClatchey mid-latitude summer, clear-sky model atmosphere, and to compare the results to those obtained in the studies mentioned above. Second, we will calculate the tropospheric methane forcing in a globally and annually averaged atmosphere with and without a representative cloud distribution in order to validate the conjecture given in IPCC (1990) that the inclusion of clouds in the forcing calculations results in forcing values which are approximately 20 percent less than those obtained using clear sky approximations

  9. Rate constants for the reactions of OH with CH3Cl, CH2Cl2, CHCl3, and CH3Br

    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.

  10. Energetics of fragmentation of CH5, H3O, and NH4 from neutralized ion-beam experiments

    Fragmentation energies for radicals of the type RH 2 (RH=CH 4 , NH 3 , and H 2 O) produced by electron capture interactions of 5 keV RH 2 + ion with Na or K atoms are reported. The experimental technique involves measurement of spatial beam profiles resulting from dissociation of neutral radicals following their formation in a near resonant electron transfer process. Cross sections for RH 2 + --Na capture reactions are typically 1x10 -14 cm 2 . Fragmentation energies from measurements with Na target atoms are -2.65 +- 0.14, -0.22 +- 0.03, and -1.12 +- 0.07 eV for CH 5 , NH 4 , and H 3 O, respectively. From our results with Na and K targets and published values for proton affinities, the vertical electron affinities of CH 5 + and H 3 O + are calculated to be 5.3 +- 0.2 eV and 5.1 +- 0.3 eV, respectively. Beam profiles for ND 4 show this species to be metastable with a lifetime of about 1 μs. From this we estimate a potential barrier to dissociation in NH 4 (ND 4 ) between 0.36 and 0.48 eV, indicating this species should be stable at low temperatures. Comparison of these experimental results with theoretical calculations indicates areas of disagreement

    The Chemistry-Aerosol Mediterranean Experiment (ChArMEx, http://charmex.lsce.ipsl.fr/) aims at a scientific assessment of the present and future state of the atmospheric environment in the Mediterranean Basin, and of its impacts on the regional climate, air quality, and marine biogeochemistry. The project includes long term monitoring of environmental parameters, intensive field campaigns, use of satellite data and modelling studies. Therefore ChARMEx scientists produce and need to access a wide diversity of data. In this context, the objective of the database task is to organize data management, distribution system and services such as facilitating the exchange of information and stimulating the collaboration between researchers within the ChArMEx community, and beyond. The database relies on a strong collaboration between OMP and ICARE data centres and falls within the scope of the Mediterranean Integrated Studies at Regional And Locals Scales (MISTRALS) program data portal. All the data produced by or of interest for the ChArMEx community will be documented in the data catalogue and accessible through the database website: http://mistrals.sedoo.fr/ChArMEx. The database website offers different tools: - A registration procedure which enables any scientist to accept the data policy and apply for a user database account. - Forms to document observations or products that will be provided to the database in compliance with metadata international standards (ISO 19115-19139; INSPIRE; Global Change Master Directory Thesaurus). - A search tool to browse the catalogue using thematic, geographic and/or temporal criteria. - Sorted lists of the datasets by thematic keywords, by measured parameters, by instruments or by platform type. - A shopping-cart web interface to order in situ data files. At present datasets from the background monitoring station of Ersa, Cape Corsica and from the 2012 ChArMEx pre-campaign are available. - A user-friendly access to satellite products

    Laboratory identification of two basic and important interstellar molecular ions is presented. The J = 1 - 0 rotational transition of {sup 12}CH{sup +} together with those of {sup 13}CH{sup +} and {sup 12}CD{sup +} was observed in the laboratory. The newly obtained frequencies were found to be different from those reported previously. Various experimental evidences firmly support the new measurements. In addition, the Zeeman effect and the spin-rotation hyperfine interaction enforce the laboratory identification with no ambiguity. Rotational lines of CH{sub 2}D{sup +} were observed in the submillimeter-wave region. This laboratory observation is consistent with a recent tentative identification of CH{sub 2}D{sup +} toward Ori IRc2.

    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.

    The CH/π hydrogen bond is the weakest extreme of hydrogen bonds that occurs between a soft acid CH and a soft base π-system. Implication in chemistry of the CH/π hydrogen bond includes issues of conformation, crystal packing, and specificity in host/guest complexes. The result obtained by analyzing the Cambridge Structural Database is reviewed. The peculiar axial preference of isopropyl group in α-phellandrene and folded conformation of levopimaric acid have been explained in terms of the CH/π hydrogen bond, by high-level ab initio MO calculations. Implication of the CH/π hydrogen bond in structural biology is also discussed, briefly.

    2018-02-01

    Quantum mechanical calculations of ro-vibrational energies of CH4, CHD3, CH3D, and CH3F were made with two different numerical approaches. Both use polyspherical coordinates. The computed energy levels agree, confirming the accuracy of the methods. In the first approach, for all the molecules, the coordinates are defined using three Radau vectors for the CH3 subsystem and a Jacobi vector between the remaining atom and the centre of mass of CH3. Euler angles specifying the orientation of a frame attached to CH3 with respect to a frame attached to the Jacobi vector are used as vibrational coordinates. A direct product potential-optimized discrete variable vibrational basis is used to build a Hamiltonian matrix. Ro-vibrational energies are computed using a re-started Arnoldi eigensolver. In the second approach, the coordinates are the spherical coordinates associated with four Radau vectors or three Radau vectors and a Jacobi vector, and the frame is an Eckart frame. Vibrational basis functions are products of contracted stretch and bend functions, and eigenvalues are computed with the Lanczos algorithm. For CH4, CHD3, and CH3D, we report the first J > 0 energy levels computed on the Wang-Carrington potential energy surface [X.-G. Wang and T. Carrington, J. Chem. Phys. 141(15), 154106 (2014)]. For CH3F, the potential energy surface of Zhao et al. [J. Chem. Phys. 144, 204302 (2016)] was used. All the results are in good agreement with experimental data.

    2014-04-01

    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.

    Quantum mechanical calculations of ro-vibrational energies of CH 4 , CHD 3 , CH 3 D, and CH 3 F were made with two different numerical approaches. Both use polyspherical coordinates. The computed energy levels agree, confirming the accuracy of the methods. In the first approach, for all the molecules, the coordinates are defined using three Radau vectors for the CH 3 subsystem and a Jacobi vector between the remaining atom and the centre of mass of CH 3 . Euler angles specifying the orientation of a frame attached to CH 3 with respect to a frame attached to the Jacobi vector are used as vibrational coordinates. A direct product potential-optimized discrete variable vibrational basis is used to build a Hamiltonian matrix. Ro-vibrational energies are computed using a re-started Arnoldi eigensolver. In the second approach, the coordinates are the spherical coordinates associated with four Radau vectors or three Radau vectors and a Jacobi vector, and the frame is an Eckart frame. Vibrational basis functions are products of contracted stretch and bend functions, and eigenvalues are computed with the Lanczos algorithm. For CH 4 , CHD 3 , and CH 3 D, we report the first J > 0 energy levels computed on the Wang-Carrington potential energy surface [X.-G. Wang and T. Carrington, J. Chem. Phys. 141(15), 154106 (2014)]. For CH 3 F, the potential energy surface of Zhao et al. [J. Chem. Phys. 144, 204302 (2016)] was used. All the results are in good agreement with experimental data.

    ROC(S)SC(O)OCH2CH3, with R = CH3sbnd , (CH3)2CHsbnd and CH3(CH2)2sbnd , were obtained through the reaction between potassium xanthate salts, ROC(S)SK, and ethyl chloroformate, ClC(O)OCH2CH3. The liquid compounds were identified and characterized by 1H and 13C NMR and mass spectrometry. The conformations adopted by the molecules were studied by DFT methods. 6 conformers were theoretically predicted for R = CH3sbnd and (CH3)2CHsbnd , while the conformational flexibility of the n-propyl substituent increases the total number of feasible rotamers to 21. For the three molecules, the conformers can be associated in 3 groups, being the most stable the AS forms - the Cdbnd S double bond anti (A) with respect to the Csbnd S single bond and the Ssbnd C single bond syn (S) with respect to the Cdbnd O double bond - followed by AA and SS conformers. The vibrational spectra were interpreted in terms of the predicted conformational equilibrium, presenting the ν(Cdbnd O) spectral region signals corresponding to the three groups of conformers. A moderated pre-resonance Raman enhancement of the ν(Cdbnd S) vibrational mode of CH3(CH2)2OC(S)SC(O)OCH2CH3 was detected, when the excitation radiation approaches the energy of a n → π∗ electronic transition associated with the Cdbnd S chromophore. UV-visible spectra in different solvents were measured and interpreted in terms of TD-DFT calculations. The unknown molecule CH3CH2OC(O)SH was isolated by the UV-visible photolysis of CH3OC(S)SC(O)OCH2CH3 isolated in Ar matrix, and also obtained as a side-product of the reaction between potassium xanthate salts, ROC(S)SK, and ethyl chloroformate, ClC(O)OCH2CH3.

    The Chemistry-Aerosol Mediterranean Experiment (ChArMEx, http://charmex.lsce.ipsl.fr/) aims at a scientific assessment of the present and future state of the atmospheric environment in the Mediterranean Basin, and of its impacts on the regional climate, air quality, and marine biogeochemistry. The project includes long term monitoring of environmental parameters, intensive field campaigns, use of satellite data and modelling studies. Therefore ChARMEx scientists produce and need to access a wide diversity of data. In this context, the objective of the database task is to organize data management, distribution system and services, such as facilitating the exchange of information and stimulating the collaboration between researchers within the ChArMEx community, and beyond. The database relies on a strong collaboration between OMP and ICARE data centres and has been set up in the framework of the Mediterranean Integrated Studies at Regional And Locals Scales (MISTRALS) program data portal. All the data produced by or of interest for the ChArMEx community will be documented in the data catalogue and accessible through the database website: http://mistrals.sedoo.fr/ChArMEx. At present, the ChArMEx database contains about 75 datasets, including 50 in situ datasets (2012 and 2013 campaigns, Ersa background monitoring station), 25 model outputs (dust model intercomparison, MEDCORDEX scenarios), and a high resolution emission inventory over the Mediterranean. Many in situ datasets have been inserted in a relational database, in order to enable more accurate data selection and download of different datasets in a shared format. The database website offers different tools: - A registration procedure which enables any scientist to accept the data policy and apply for a user database account. - A data catalogue that complies with metadata international standards (ISO 19115-19139; INSPIRE European Directive; Global Change Master Directory Thesaurus). - Metadata forms to document

    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.

    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.

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

    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.

    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

    Although the hygroscopicity of a NaNO(3)/water microdroplet and a polyalcohol/water microdroplet, two of the most important aerosols in atmosphere, has been widely studied, little is known about the relationship between the hygroscopic behavior of mixed NaNO(3)/polyalcohol/water droplets and their structures on the molecular level. In this study, the hygroscopicity of mixed glycerol/NaNO(3)/water droplets deposited on a hydrophobic substrate was studied by micro-Raman spectroscopy with organic-to-inorganic molar ratios (OIRs) of 0.5, 1, and 2. In the mixed glycerol/NaNO(3)/water droplets, glycerol molecules tended to combine with Na(+) and NO(3)(-) ions by electrostatic interaction and hydrogen bonding, respectively. On the basis of the analyses of the changes of symmetric stretching (v(s)-CH(2)), asymmetric stretching (v(a)-CH(2)), their area ratio (Av(a)-CH(2)/Av(s)-CH(2)) of glycerol, and symmetric stretching band of NO(3)(-) (ν(1)-NO(3)(-)) with relative humidity (RH), it was found that the conformation of glycerol was transformed from αα mainly to γγ and partly to αγ with a decreasing RH in the mixed droplets, contrary to the case in the glycerol/water droplet. In addition, the glycerol with γγ and αγ conformation had strong interaction with Na(+) and NO(3)(-) respectively, which suppressed the formation of contact of ions and delayed the efflorescence relative humidity (ERH) for the mixed droplets compared to the NaNO(3)/water droplet. © 2012 American Chemical Society

    A distinction is made between primary and secondary isotope effects, the primary ones being based on the relative large vibrational frequencies and ensuing large zeroprint energies for C-H vibrations whereas the secondary effects are observed in systems where the vibrational modes of the isotopically labelled site are perturbed during transformation from reactant to product. Both effects are utilised in the elucidation of mechanism in pericyclic processes. The main processes dealt with in this chapter are cycloadditions of all types and sigmatropic rearrangements

    Integral cross sections were measured for two reactions occurring in CH + +O - collisions: the formation of the carbon monoxide cation CO + via a reactive ionization process and the formation of the (iso)formyl cation HCO + (HOC + ) via the associative ionization process. Both carbon monoxide and formyl cations are present in the interstellar medium, the latter one being quite abundant in dense clouds. Provided the oxygen anion would also be present in the interstellar environment, the large efficiency of the two reactive processes reported here would justify their inclusion in astrochemical models. The whole set of data was obtained by means of a merged-beam setup operating with keV beams

    Full Text Available Dobrovolné izometrické cvičení (VOL i neuromuskulární elektrická stimulace (NMES jsou metody rozvoje statické svalové síly. Používají se v programech pro rozvoj síly u zdravých svalů a také pro zotavování svalové funkce za určitých ortopedických podmínek. Obě metody se používají pro zpomalování svalové atrofie a ztráty síly v důsledku imobilizace kolena po zranění (Eriksson & Häggmark, 1979; Ingemann-Hansen & Halkjær-Kristensen, 1985; Johnson, 1988; Wigerstad-Lossing, Tromby, Jonsson, Morelli, Peterson, & Rentröm, 1988. NMES může vyvolat záškuby nebo tetanické svalové kontrakce, a to v závislosti na frekvenci proudových impulsů. Během tetanické stimulace jsou hlavními rysy nácvikových režimů: 1 cyklus zapnutí/vypnutí (pracovní cyklus, tvořený dobou kontrakce a dobou uvolnění; 2 počet kontrakcí; 3 intenzita kontrakcí (dána proudovou amplitudou nebo tolerancí subjektu. Voluntary isometric exercise (VOL and neuromuscular electrical stimulation (NMES are both methods of static muscle strength and girth training. They are applied in strength training programs to healthy muscle as well as for muscle function recovery under certain orthopaedic conditions. Both methods are used to retard muscle atrophy and strength loss resulting from post injury knee immobilization (Eriksson & Häggmark, 1979; Ingemann-Hansen & Halkjær-Kristensen, 1985; Johnson, 1988; Wigerstad-Lossing, Tromby, Jonsson, Morelli, Peterson, & Rentröm, 1988. NMES can elicit twitch or tetanic muscle contractions, determined by current pulse frequency. During tetanic stimulation, the main features of training regimes are: 1 on/off cycle (or duty cycle, made up of the time of contraction plus rest time; 2 the number of contractions; 3 the intensity of contractions (determined by the current amplitude and/or the subject’s tolerance.

  18. Parallel factor ChIP provides essential internal control for quantitative differential ChIP-seq.

    2018-04-17

    A key challenge in quantitative ChIP combined with high-throughput sequencing (ChIP-seq) is the normalization of data in the presence of genome-wide changes in occupancy. Analysis-based normalization methods were developed for transcriptomic data and these are dependent on the underlying assumption that total transcription does not change between conditions. For genome-wide changes in transcription factor (TF) binding, these assumptions do not hold true. The challenges in normalization are confounded by experimental variability during sample preparation, processing and recovery. We present a novel normalization strategy utilizing an internal standard of unchanged peaks for reference. Our method can be readily applied to monitor genome-wide changes by ChIP-seq that are otherwise lost or misrepresented through analytical normalization. We compare our approach to normalization by total read depth and two alternative methods that utilize external experimental controls to study TF binding. We successfully resolve the key challenges in quantitative ChIP-seq analysis and demonstrate its application by monitoring the loss of Estrogen Receptor-alpha (ER) binding upon fulvestrant treatment, ER binding in response to estrodiol, ER mediated change in H4K12 acetylation and profiling ER binding in patient-derived xenographs. This is supported by an adaptable pipeline to normalize and quantify differential TF binding genome-wide and generate metrics for differential binding at individual sites.

  3. InChIKey collision resistance: an experimental testing

    Directory of Open Access Journals (Sweden)

    2012-12-01

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

    Integral cross sections were measured for two reactions occurring in CH++O- collisions: the formation of the carbon monoxide cation CO+ via a reactive ionization process and the formation of the (iso)formyl cation HCO+ (HOC+) via the associative ionization process. Both carbon monoxide and formyl cations are present in the interstellar medium, the latter one being quite abundant in dense clouds. Provided the oxygen anion would also be present in the interstellar environment, the large efficiency of the two reactive processes reported here would justify their inclusion in astrochemical models. The whole set of data was obtained by means of a merged-beam setup operating with keV beams.

In the clinic, this antibody has been shown to be effective in the treatment of children with high-risk neuroblastoma, either alone or in combination therapy. Extensive product characterization is a prerequisite to addressing the potential issues of product variability associated with process changes and manufacturing scale-up. Charge heterogeneity, glycosylation profile, molecular state and aggregation, interaction (affinity) with Fcγ receptors and functional or biological activities are a few of the critical characterization assays for assessing product comparability for this antibody. In this article, we describe the in-house development and qualification of imaged capillary isoelectric focusing to assess charge heterogeneity, analytical size exclusion chromatography with online static and dynamic light scattering (DLS), batch mode DLS for aggregate detection, biosensor (surface plasmon resonance)-based Fcγ receptor antibody interaction kinetics, N-glycoprofiling with PNGase F digestion, 2-aminobenzoic acid labeling and high performance liquid chromatography and N-glycan analysis using capillary electrophoresis. In addition, we studied selected biological activity assays, such as complement-dependent cytotoxicity. The consistency and reproducibility of the assays are established by comparing the intra-day and inter-day assay results. Applications of the methodologies to address stability or changes in product characteristics are also reported. The study results reveal that the ch14.18 clinical product formulated in phosphate-buffered saline at a concentration of 5 mg/ml and stored at 2–8°C is stable for more than five years. PMID:22327432

    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.

    Full Text Available Purpose of the article: The focus of this article are lump sum and regular investments on selected world stock markets in the period from 1990 to 2010 for different investment horizons. Methodology/methods: The Methodology used in this Paper is based on the quantification of return and risk indicators for different investment horizons. 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.

    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

  20. Fluid properties control degassing or storage of abiogenic CH4 during slab exhumation: the fluid inclusion record from the Western Alps.

    Science.gov (United States)

    Ferrando, S.; Castelli, D.; Frezzotti, M. L.

    2017-12-01

    Abiogenic CH4 can be produced by interaction between carbonates and reducing fluids derived from the hydration of ultramafics (e.g., mantle peridotite or HP Ol-serpentinite). This process occurs during slab exhumation because cooling promotes serpentinization of olivine in presence of water (Fo + H2O = Atg + Brc and the linked reactions: Fa + H2O = Fe-Atg + Mag + H2 and Atg + CaCO3 + H2 = Di + Brc + CH4 + H2O) at ca. 500-375°C (P=2.0-0.2 GPa). Experiments in the CH4-H2O-NaCl system indicate that, at these conditions, fluids are immiscible even for very low salinity (ca. 3 wt%) and that the NaCl content in the aqueous part of the fluid increases with temperature whereas the CH4 content in the gaseous part shows an opposite trend (Lamb et al., 2002; Li, 2017).In HP rodingite from the Piemonte ophiolite Zone (W Alps), primary fluid inclusions consisting of a brine (6 wt% CaCl2 + 6 wt% NaCl) with H2 + CH4 ≤ 1 mol % [CH4/(H2+CH4) = 0.37-10] occur in vesuvianite veins that formed at P=0.2 GPa and T=375°C. We interpret them as the aqueous part of an immiscible reducing fluid produced during late Alpine serpentinization of the surrounding ultramafics. Interestingly, CH4-H2 gaseous fluids are never reported in rodingite, whereas early CH4-H2O-H2±graphite and CH4-H2±graphite fluid inclusions, with variable gas-water proportions, trapped in calcite at P≤1.0 GPa and T≤450°C, are recently reported from HP "graphitized" ophicarbonate from the Lanzo peridotite Massif (W Alps; Vitale Brovarone et al., 2017).Both HP ophiolites and partially-serpentinized peridotite massifs are, thus, efficient lithologies to produce CH4 during exhumation. The amount of released CH4 depends on the amount of water available during exhumation. However, when fluids immiscibility occurs, the gaseous-rich part (CH4-H2) of the immiscible fluid produced in ultramafics likely remains confined in the slab because it is less mobile with respect to the aqueous-rich part due to its high dihedral

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.

    Thermochemistry of reactants, intermediates, transition state structures, and products along with kinetics on the association of CH2·C(═O)CH2CH3 (2-butanone-1-yl) with O2 and dissociation of the peroxy adduct isomers are studied. Thermochemical properties are determined using ab initio (G3MP2B3 and G3) composite methods along with density functional theory (B3LYP/6-311g(d,p)). Entropy and heat capacity contributions versus temperature are determined from structures, vibration frequencies, and internal rotor potentials. The CH2·C(═O)CH2CH3 radical + O2 association results in a chemically activated peroxy radical with 27 kcal mol(-1) excess of energy. The chemically activated adduct can react to stabilized peroxy or hydroperoxide alkyl radical adducts, further react to lactones plus hydroxyl radical, or form olefinic ketones and a hydroperoxy radical. Kinetic parameters are determined from the G3 composite methods derived thermochemical parameters, and quantum Rice-Ramsperger-Kassel (QRRK) analysis to calculate k(E) with master equation analysis to evaluate falloff in the chemically activated and dissociation reactions. One new, not previously reported, peroxy chemistry reaction is presented. It has a low barrier path and involves a concerted reaction resulting in olefin formation, H2O elimination, and an alkoxy radical.

    2018-03-15

    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 sec/MB using general purpose computers.

    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

    The synthesis and characterization of the rare earth chalcogenide aerogels NaYSnS4, NaGdSnS4, and NaTbSnS4 is reported. Rare earth metal ions like Y3+, Gd3+, and Tb3+ react with the chalcogenide clusters [SnS4]4– in aqueous formamide solution forming extended polymeric networks by gelation. 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.

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

    2010-01-01

    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.

  12. Effects of Boreal Lake Wetlands on Atmospheric 13CH3D and 12CH2D2

    2017-12-01

    Recently, we developed a theoretical model to investigate the potential use of 13CH3D and 12CH2D2 as tools for tracking atmospheric methane budget. We used electronic structure methods to estimate kinetic isotope fractionations associated with the major sink reactions of CH4 in air (reactions with •OH and Cl•), and literature data with reconnaissance measurements of the relative abundances of 13CH3D and 12CH2D2 to estimate the compositions of the largest atmospheric sources. Here we present new methane rare isotopologue data from boreal wetlands, comprising one of the most important sources, in order to evaluate the robustness of the model. Boreal wetlands (>55° N) account for more than half of the wetland area in the Northern hemisphere. We analyzed methane samples from high latitude lakes representing different geographical regions, geological and ecological contexts, methane fluxes, and isotopic signatures. Using clumped isotopes of CH4 we are able to determine the likely production mechanism for natural CH4 samples. So far, all of our analyzed samples except one plot in the microbial pure-culture methanogenesis field (Young et al. 2017) with ranges of -0.2‰ to +1.2‰ for Δ13CH3D, and -29.6‰ to -18.2‰ for Δ12CH2D2. These compositions are far from equilibrium. The one exception, from Lake Doughnut, Alaska, exhibits Δ13CH3D and Δ12CH2D2 values of +5.2‰ and +18.7‰, respectively, which fall near ambient thermodynamic equilibrium values. This may be an effect of methanotrophy. Mean Δ13CH3D and Δ12CH2D2 for all lake samples are +1.7‰ and -15.4‰ respectively, compared to our original estimate of +6.1‰ and +21.2‰ for the wetland methane source based on an assumption of equilibrium. If we assume that these samples are representative of the overall wetland source, Δ13CH3D decreases by 0.8‰ and Δ12CH2D2 decreases by 0.6‰ in our model of bulk atmospheric methane. Δ13CH3D and Δ12CH2D2 values of air (including •OH and Cl• sink

    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.

    2016-02-07

    Heterocyclic compounds are widely present in natural products, pharmaceuticals and bioactive molecules. Thus, organic and pharmaceutical chemists have been making extensive efforts to construct those heterocyclic frameworks through developing versatile and efficient synthetic strategies. The direct C-H functionalization via the radical pathway has emerged as a promising and dramatic approach towards heterocycles with high atom- and step-economy. Heterocyclic compounds such as coumarins, furans, benzofurans, xanthones, benzothiazoles, indoles, indolines, oxindoles, quinolines, isoquinolines, quinoxaline, and phenanthridines have been successfully synthesized by C-H functionalization through the radical pathway. In this review, recent advances on radical C-H functionalization to construct heterocyclic compounds are highlighted with discussions.

    Carbon-heteroatom bonds represent omnipresent structural motifs of the vast majority of functionalized materials and bioactive compounds. C-H activation has emerged as arguably the most efficient strategy to construct C-Het bonds. Despite of major advances, these C-H transformations were largely dominated by precious transition metal catalysts, in combination with stoichiometric, toxic metal oxidants. Herein, we discuss the recent evolution of cobalt-catalyzed C-H activations that enable C-Het formations with electricity as the sole sustainable oxidant until May 2018. © 2018 WILEY-VCH Verlag GmbH & Co.

    Avian leukosis virus subgroup J (ALV-J), an oncogenic retrovirus, induces myelocytomas and other various tumors, leading to great economical losses in poultry industry. It is a great challenge to develop effective preventive methods for ALV-J control due to its antigenic variations in the variable regions of envelope. In present study, we generated a mouse polyclonal antibody targeting the first extracellular loop (ECL1) of chicken Na + /H + exchanger isoform 1 (chNHE1), the receptor of ALV-J, to block ALV-J infection in vitro and in vivo. In ALV-J infected DF-1 cells, chNHE1 expression and the intracellular pH (pHi) were up-regulated with "wave" pattern, indicating that the disequilibrium of ALV-J infected cells associated with chNHE1. Next, we validated that ALV-J infection was significantly blocked with time dependent after treating with anti-ECL1 antibody and accordingly the pHi value were recovered, indicating the blockage of ALV-J infection did not affect Na + /H + exchange. Furthermore, in anti-ECL1 antibody treatment chickens that infected by ALV-J, weight gain and immune organs were recovered, and viral loads were significantly decreased, and the tissue injury and inflammation were reduced significantly from 21 to 35 days of age. The study demonstrated that anti-ECL1 antibody effectively blocks ALV-J infection without affecting Na + /H + exchange, and sheds light on a novel strategy for retroviruses control.

  3. 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.

    2017-12-01

    Full Text Available Cats are usually spreaders of allergens that are critical for sensitive people; the Siberian cat is a breed supposed to be low level allergenic, according to some breeders’ statements. The sequence of the two genes, namely Ch1 and Ch2, that code for the allergen Fel d 1, the major allergen responsible for outbreaks of allergy symptoms, is not yet known in the Siberian cat, and finding this was the aim of our investigation. Notably, our work is the first survey of the genetic structure of these genes in Siberian cats. 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.

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.

    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.

    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.

    Abstract : Organic electronics is a rapidly growing field driven in large part by the synthesis of ∏-conjugated molecules and polymers. Traditional aryl cross-coupling reactions such as the Stille and Suzuki have been used extensively in the synthesis of ∏-conjugated molecules and polymers, but the synthesis of intermediates necessary for traditional cross-couplings can include multiple steps with toxic and hazardous reagents. Direct arylation through C-H bond activation has the potential to reduce the number of steps and hazards while being more atom-economical. Within the Center for Selective C-H Functionalization (CCHF), we have been developing C-H activation methodology for the synthesis of ∏-conjugated materials of interest, including direct arylation of difficult-to-functionalize electron acceptor intermediates and living polymerization of ∏-conjugated polymers through C-H activation.

    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.

  3. Side chain mobility as monitored by CH-CH cross correlation: The example of cytochrome b5

    2001-01-01

    The mobility of βCH 2 moieties in oxidized and reduced cytochrome b 5 was studied by analyzing the 13 C relaxation of the J-split components, in terms of C-H dipole-C-H dipole cross correlation rates. A 2D 13 C- 1 H experiment is proposed to measure these rates that provide the internal effective reorientation correlation time for each CH 2 moiety. It is found that higher mobility is present in the α helices forming the heme pocket. On the contrary, the β strands, which form the hydrophobic core of the molecule, have the lowest mobility. The general pattern is the same for the oxidized and reduced species, indicating that any oxidation-dependent property detected for backbone NH moieties does not affect the CH 2 mobility

    The advent of high-throughput technologies such as ChIP-seq has made possible the study of histone modifications. A problem of particular interest is the identification of regions of the genome where different cell types from the same organism exhibit different patterns of histone enrichment. This problem turns out to be surprisingly difficult, even in simple pairwise comparisons, because of the significant level of noise in ChIP-seq data. In this paper we propose a two-stage statistical method, called ChIPnorm, to normalize ChIP-seq data, and to find differential regions in the genome, given two libraries of histone modifications of different cell types. We show that the ChIPnorm method removes most of the noise and bias in the data and outperforms other normalization methods. We correlate the histone marks with gene expression data and confirm that histone modifications H3K27me3 and H3K4me3 act as respectively a repressor and an activator of genes. Compared to what was previously reported in the literature, we find that a substantially higher fraction of bivalent marks in ES cells for H3K27me3 and H3K4me3 move into a K27-only state. We find that most of the promoter regions in protein-coding genes have differential histone-modification sites. The software for this work can be downloaded from http://lcbb.epfl.ch/software.html.

  8. Photolysis of CH3CHO at 248 nm: Evidence of triple fragmentation from primary quantum yield of CH3 and HCO radicals and H atoms

    Radical quantum yields have been measured following the 248 nm photolysis of acetaldehyde, CH3CHO. HCO radical and H atom yields have been quantified by time resolved continuous wave Cavity Ring Down Spectroscopy in the near infrared following their conversion to HO2 radicals by reaction with O2. The CH3 radical yield has been determined using the same technique following their conversion into CH3O2. Absolute yields have been deduced for HCO radicals and H atoms through fitting of time resolved HO2 profiles, obtained under various O2 concentrations, to a complex model, while the CH3 yield has been determined relative to the CH3 yield from 248 nm photolysis of CH3I. Time resolved HO2 profiles under very low O2 concentrations suggest that another unknown HO2 forming reaction path exists in this reaction system besides the conversion of HCO radicals and H atoms by reaction with O2. HO2 profiles can be well reproduced under a large range of experimental conditions with the following quantum yields: CH3CHO + hν248nm → CH3CHO*, CH3CHO* → CH3 + HCO ϕ1a = 0.125 ± 0.03, CH3CHO* → CH3 + H + CO ϕ1e = 0.205 ± 0.04, CH3CHO*{to 2pc{rArrfill}}limits^{o2}CH3CO + HO2 ϕ1f = 0.07 ± 0.01. The CH3O2 quantum yield has been determined in separate experiments as φ_{CH3} = 0.33 ± 0.03 and is in excellent agreement with the CH3 yields derived from the HO2 measurements considering that the triple fragmentation (R1e) is an important reaction path in the 248 nm photolysis of CH3CHO. From arithmetic considerations taking into account the HO2 and CH3 measurements we deduce a remaining quantum yield for the molecular pathway: CH3CHO* → CH4 + CO ϕ1b = 0.6. All experiments can be consistently explained with absence of the formerly considered pathway: CH3CHO* → CH3CO + H ϕ1c = 0.

    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.

    Infrared spectra for the title compounds were measured experimentally in 700 Torr of air at 295 K and systematically modeled in B3LYP, M06-2X and MP2 calculations employing various basis sets. Calibrated infrared spectra over the wavenumber range 600–3500 cm"−"1 are reported and combined with literature data to provide spectra for use in experimental studies and radiative transfer calculations. Integrated absorption cross sections are (units of cm"−"1 molecule"−"1): CH_3Cl, 660–780 cm"−"1, (3.89±0.19)×10"−"1"8; CH_2Cl_2, 650–800 cm"−"1, (2.16±0.11)×10"−"1"7; CHCl_3, 720–810 cm"−"1, (4.08±0.20)×10"−"1"7; and CCl_4, 730–825 cm"−"1, (6.30±0.31)×10"−"1"7. CH_3Cl, CH_2Cl_2, CHCl_3, and CCl_4 have radiative efficiencies of 0.004, 0.028, 0.070, and 0.174 W m"−"2 ppb"−"1 and global warming potentials (100 year horizon) of 5, 8, 15, and 1775, respectively. Quantum chemistry calculations generally predict larger band intensities than the experimental values. The best agreement with experiments is obtained in MP2(Full) calculations employing basis sets of at least triple-zeta quality augmented by diffuse functions. The B3LYP functional is found ill-suited for calculating vibrational frequencies and infrared intensities of halocarbons. - Highlights: • Infrared spectra reported for CH_3Cl, CH_2Cl_2, CHCl_3, and CCl_4. • REs of CH_3Cl, CH_2Cl_2, CHCl_3, and CCl_4 are 0.004, 0.028, 0.070, and 0.174 W m"−"2 ppb"−"1, respectively. • GWPs of CH_3Cl, CH_2Cl_2, CHCl_3, and CCl_4 are 5, 8, 15, and 1775, respectively.

    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.

    We have simulated the photoelectron spectrum of CH - 2 using the model described previously [Sears and Bunker, J. Chem. Phys. 79, 5265 (1983)]. The optimization of the fit of the simulated spectrum to the recently observed spectrum of Lineberger and co-workers [J. Chem. Phys. 81, 1048 (1984) and preceding paper] has enabled us to determine the rotation-bending energy levels of triplet CH 2 over an energy range of more than 1 eV. It has also enabled us to determine that the rotational temperature of the CH - 2 in the experiment is 220 K and that, for v 2 = 1, the vibrational temperature is 680 K. For CH - 2 we determine that a/sub e/ = 103 0 and that ν 2 = 1230 cm -1 . The singlet--triplet splitting in methylene is determined to be 3150 +- 30 cm -1 (0.3905 +- 0.004 eV, 9.01 +- 0.09 kcal/mol) from the photoelectron spectrum, in excellent agreement with the more accurate value previously obtained from LMR spectroscopy [McKellar et al., J. Chem. Phys. 79, 5251 (1983)] of 3165 +- 20 cm -1 (0.3924 +- 0.0025 eV, 9.05 +- 0.06 kcal/mol), and the electron affinity of triplet CH 2 is determined to be 0.652 +- 0.006 eV

  18. Modeling ChIP sequencing in silico with applications.

    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)

    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)

Zásadní změny využití krajiny jsou v tomto území spojeny s procesy zemědělské intenzifikace a urbanizace. Nejvyšší výměra vodních ploch byla zaznamenána v obou povodích v roce 1763. V druhé polovině 19. století se významně projevily zásadní hybné síly vedoucí k zániku většiny vodních ploch v obou povodích. Po druhé světové válce došlo k obnově některých vodních ploch v povodí Kyjovky, zároveň byly zakládány i nové rybníky. Naopak v povodí Trkmanky nebyly obnoveny žádné významné vodní plochy.

    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.

    2017-01-01

    Aims: Poorly drained arctic ecosystems are potential large emitters of methane (CH4) due to their high soil organic carbon content and low oxygen availability. In wetlands, aerenchymatous plants transport CH4 from the soil to the atmosphere, but concurrently transport O2 to the rhizosphere, which...... may lead to oxidation of CH4. The importance of the latter process is largely unknown for arctic plant species and ecosystems. Here, we aim to quantify the subsurface oxidation of CH4 in a waterlogged arctic ecosystem dominated by Carex aquatilis ssp. stans and Eriophorum angustifolium, and evaluate...... during three weeks after addition of 13C-enriched CH4 below the mesocosm. Results: Most of the recovered 13C label (>98 %) escaped the ecosystem as CH4, while less than 2 % was oxidized to 13CO2. Conclusions: It is concluded that aerenchymatous plants control the overall CH4 emissions but, as a transport...

    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.

    The temperature variation of the rate coefficient for k(1) for CH3(+) + H2 yields CH5(+) + hv is computed treating the para and ortho forms of H2 separately, taking account of nuclear spin and using an accurate theory of the kinetics of association. The results are made absolute with the aid of the measurement at 13 K by Barlow et al. (1984). By combining this measurement with the CH5(+) vibrational frequencies obtained by Pople (1984) from a quantal study, it is deduced that the probability of the stabilizing radiative transition is 5400/s. The rate coefficients k(1) (T, para) and k(1) (T, ortho) are given at 13 K, 30 K, and 80 K. 23 references

    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.

    Results are discussed for low-resolution uv observations of the symbiotic star CH Cyg and of the eclipsing binary VV Cep during chromospheric eclipse following totality. The far-uv and absorption-line spectra of CH Cyg and VV Cep are found to be remarkably similar. It is shown that the energy distribution for CH Cyg is very similar to that of an A0 V star and that the energy distribution for VV Cep is similar to that of an A0-A2 star. Evidence is cited for an extended envelope surrounding the M supergiant component of VV Cep, and an absolute visual magnitude of about -2 is estimated for this system.

  17. 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.

    By using a so-called 'stream technique', which consists of flowing gas in laminar regime along a quartz tube, we determine that CH 3 radicals are completely removed from the pumped mixture (CH 4 /C X H Y /H 2 /H/CH 3 ) after several hundred collisions with the inner surface of a stainless steel insert (T = 380-470 K). The methyl sticking coefficient decreased to ∼10 -6 and the recombination coefficient increased up to ∼0.01 at impingement with the metal surface. After passing through the heated zone no hydrocarbon deposition occurred at 300 K. However, unsaturated hydrocarbons, which formed in discharge zone and appeared as a result of interaction of radicals with stainless steel, condensed in a liquid phase at a temperature of ∼130 K and partial pressure of 0.01-0.1 Pa. Liquid films underwent partial polymerization and formed island deposits, which were stable at 300 K

  19. The Drivers of the CH4 Seasonal Cycle in the Arctic and What Long-Term Observations of CH4 Imply About Trends in Arctic CH4 Fluxes

    The large seasonal change in the atmospheric column for CH4 in the Arctic is driven by two dominant processes: transport of CH4 from low latitudes and surface emissions throughout the Arctic region. The NOAA ESRL Carbon Cycle Group Aircraft Program along with the NASA funded Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) have initiated an effort to better understand the factors controlling the seasonal changes in the mole fraction of CH4 in the Arctic with a multi-scale aircraft observing network in Alaska. The backbone of this network is multi-species flask sampling from 500 to 8000 masl that has been conducted every two weeks for the last 10 years over Poker Flat, AK. In addition regular profiles at the interior Alaska site at Poker Flat, NOAA has teamed up with the United States Coast Guard to make profiling flights with continuous observations of CO2, CO, CH4 and Ozone between Kodiak and Barrow every 2 weeks. More recently, CARVE has significantly added to this observational network with targeted flights focused on exploring the variability of CO2, CH4 and CO in the boundary layer both in the interior and the North Slope regions of Alaska. Taken together with the profiling of HIAPER Pole-to-Pole Observations (HIPPO), ground sites at Barrow and a new CARVE interior Alaska surface site just north of Fairbanks, AK, we now have the ability to investigate the full evolution of the seasonal cycle in the Arctic using both the multi-scale sampling offered by the different aircraft platforms as well as the multi-species sampling offered by in-situ and flask sampling. The flasks also provide a valuable tie-point between different platforms so that spatial and temporal gradients can be properly interpreted. In the context of the seasonal cycle observed by the aircraft platforms we will look at long term ground observations over the last 20 years to assess changes in Arctic CH4 emissions which have occurred as a result of 0.6C/decade changes in mean surface

  2. Macromolecule simulation and CH4 adsorption mechanism of coal vitrinite

    Science.gov (United States)

    Yu, Song; Yan-ming, Zhu; Wu, Li

    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 reactive collision of the CH+ molecular ion with an electron is studied in the framework of the multichannel quantum defect theory, taking into account the contribution of the core-excited Rydberg states. In addition to the X 1Σ+ ground state of the ion, we also consider the contribution to the dynamics of the a 3Π and A 1Π excited states of CH+. Our results—in the case of the dissociative recombination in good agreement with the storage ring measurements—rely on decisive improvements—complete account of the ionisation channels and accurate evaluation of the reaction matrix—of a previously used model.

    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

  12. On the feasibility of chemi-ion formation in the system CH2CH(ã 4A″)+O(3P)

    2003-12-01

    We have investigated theoretically the possibility that the CH2CH(ã 4A″) radical can generate the CH2CHO+(X1A') ion upon collisions with O(3P). We have concluded that this is very unlikely because the minimum of the ground-state potential-energy surface of the ion is at about the same level as the potential energy of the asymptotic CH2CH(ã 4A″)+O(3P) fragments. In addition the Franck-Condon factors should not be favorable because of a drastic change in the geometry of the ion.

    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

    Full Text Available Cílem empirické studie je prezentace výsledků obsahové analýzy didaktického aparátu učebnic a cvičebnic školního vzdělávacího předmětu prvouka/přírodověda určených pro žáky 1. stupně základních škol z hlediska jejich zaměření na výchovu ke zdraví. V první části studie prezentujeme teoretický základ našeho výzkumu, který spočíval ve vymezení analytických kategorií vyplývajících z holistického pojetí zdraví. V druhé části představujeme cíle a metody výzkumu, výzkumný vzorek sestávající z pěti současných ucelených učebnicových řad učebnic prvouky/ přírodovědy (38 učebnic/cvičebnic; 3136 zkoumaných jednotek, tedy otázek, námětů a úkolů zařazených do učebnic platných pro 1. stupeň základního vzdělávání. Třetí část je věnována výsledkům analýzy, která poukázala na významné rozdíly v prezentaci učiva v oblasti výchova ke zdraví. Z výsledků vyplývá nereflektování holistického pojetí zdraví v jeho plném rozsahu, majoritní zastoupení biologického kontextu zdraví ve zkoumaných učebnicích. Holistické pojetí zdraví nejvíce reflektují učebnice druhých ročníků. Dále poukazujeme na významné rozdíly ve strukturaci učiva v rámci jednotlivých učebnicových řad (absence tematiky zdraví ve většině zkoumaných učebnic 4. ročníků a nestabilitu v distribuci tematických celků zkoumaného vzorku učebnic. V závěru studie (čtvrtá a pátá část jsou diskutovány výsledky, možnosti a limity studie a představujeme eventuality navazujícího výzkumného šetření.

  18. Koncentrace pozornosti jako předpoklad výkonu u sportovců v juniorských kategoriích ve vytrvalostních sportech Concentration of attention as a predisposition of performance in junior categories in endurance sports

    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

    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
