    Radioimmunoscintigraphy (RIS) using human monoclonal antibodies offers the important clinical advantage of repeated imaging over murine monoclonal antibodies by eliminating the cross-species antibody response. This article reports a Phase I-II clinical trial with Tc-99m-labeled, totally human monoclonal antibody 88BV59H21-2 in patients with colorectal carcinoma. The study population consisted of 34 patients with colorectal cancer (20 men and 14 women; age range, 44-81 years). Patients were administered 5-10 mg antibody labeled with 21-41 mCi Tc-99m by the i.v. route and imaged at 3-10 and 16-24 h after infusion using planar and single-photon emission computed tomographic (CT) techniques. Pathological confirmation was obtained in 25 patients who underwent surgery. Human antihuman antibody (HAHA) titers were checked prior to and 1 and 3 months after the infusion. RIS with Tc-99m-labeled 88BV59H21-2 revealed a better detection rate in the abdomen-pelvis region compared with axial CT. The combined use of both modalities increased the sensitivity in both the liver and abdomen-pelvis regions. Ten patients developed mild adverse reactions (chills and fever). No HAHA response was detected in this series. Tc-99m-labeled human monoclonal antibody 88BV59H21-2 RIS shows promise as a useful diagnostic modality in patients with colorectal cancer. RIS alone or in combination with CT is more sensitive than CT in detecting tumor within the abdomen and pelvis. Repeated RIS studies may be possible, due to the lack of a HAHA response. PMID:7493345

    2005-01-01

    . Using amide hydrogen/deuterium exchange monitored by mass spectrometry, we show that Delta K58-beta(2)m has increased unfolding rates compared to wt-beta(2)m and that unfolding is highly temperature dependent. The unfolding rate is I order of magnitude faster in Delta K58-beta(2)M than in wt-beta(2)m...... fluorescence. After a few days at 37 degrees C, in contrast to wt-beta(2)M, Delta K-58-beta(2)M forms well-defined high molecular weight aggregates that are detected by size-exclusion chromatography.

    Inflammation plays a central role in the development and progression of diabetic nephropathy (DN). Researches on novel anti-inflammatory agents may offer new opportunities for the treatment of DN. We previously found a chalcone derivative L6H21 could inhibit LPS-induced cytokine release from macrophages. The aim of this study was to investigate whether L6H21 could ameliorate the high glucose-mediated inflammation in NRK-52E cells and attenuate the inflammation-mediated renal injury. According to the results, L6H21 showed a great inhibitory effect on the expression of pro-inflammatory cytokines, cell adhesion molecules, chemokines, and macrophage adhesion via down-regulation of NF-κB/MAPKs activity in high glucose-stimulated renal NRK-52E cells. Further, in vivo oral administration with L6H21 at a dosage of 20 mg/kg/2 days showed a decreased expression of pro-inflammatory cytokines, cell adhesion molecules, which subsequently contributed to the inhibition on renal macrophage infiltration, the reduction of serum creatinine and BUN levels, and the improvement on the fibrosis and pathological changes in the renal tissues of diabetic mice. These findings provided that chalcone derived L6H21 may be a promising anti-inflammatory agent and have the potential in the therapy of diabetic nephropathy, and importantly, MAPK/NF-κB signaling system may be a novel therapeutic target for human DN in the future. - Highlights: • Inflammation plays a central role in the development of diabetic nephropathy. • Compound L6H21 reduced the high glucose-mediated inflammation in NRK-52E cells. • Compound L6H21 attenuated the inflammation-mediated renal injury. • L6H21 exhibited anti-inflammatory effects via inactivation of NF-κB/MAPKs. • MAPKs/NF-κB may be a novel therapeutic target in diabetic nephropathy treatment.

  3. Survival in acidic and alcoholic medium of Shiga toxin-producing Escherichia coli O157:H7 and non-O157:H7 isolated in Argentina

    Sanz Marcelo E

    2003-08-01

    Full Text Available Abstract Background In spite of Argentina having one of the highest frequencies of haemolytic uraemic syndrome (HUS, the incidence of Escherichia coli O157:H7 is low in comparison to rates registered in the US. Isolation of several non-O157 shiga toxin-producing Escherichia coli (STEC strains from cattle and foods suggests that E. coli O157:H7 is an uncommon serotype in Argentina. The present study was undertaken to compare the survival rates of selected non-O157 STEC strains under acidic and alcoholic stress conditions, using an E. coli O157:H7 strain as reference. Results Growth at 37°C of E. coli O26:H11, O88:H21, O91:H21, O111:H-, O113:H21, O116:H21, O117:H7, O157:H7, O171:H2 and OX3:H21, was found to occur at pH higher than 4.0. When the strains were challenged to acid tolerance at pH as low as 2.5, viability extended beyond 8 h, but none of the bacteria, except E. coli O91:H21, could survive longer than 24 h, the autochthonous E. coli O91:H21 being the more resistant serotype. No survival was found after 24 h in Luria Bertani broth supplemented with 12% ethanol, but all these serotypes were shown to be very resistant to 6% ethanol. E. coli O91:H21 showed the highest resistance among serotypes tested. Conclusions This information is relevant in food industry, which strongly relies on the acid or alcoholic conditions to inactivate pathogens. This study revealed that stress resistance of some STEC serotypes isolated in Argentina is higher than that for E. coli O157:H7.

  5. A performance assessment of source correlation and weathering indices for petroleum hydrocarbons in the environment

    The source of petroleum contaminants in the environment and the extent to which these contaminants have weathered following deposition can often be determined through an empirical evaluation of oil n-alkanes, isoprenoids (pristane and phytane), and hopane and sterane biomarkers. Common source correlation and weathering indices have been calculated for three sets of oil samples: fresh, 25% (w/w) weathered, and 50% (w/w) physically weathered diesel standards, crude oils from different sources, and a set of representative heavy oils. For the weathered diesel oils, the C18:phytane demonstrated low specificity between the oils. C18:17α(H),21β(H)-Hopane and n-alkanes:17α(H),21β(H)-hopane differentiated between crude oils but would be expected to vary significantly during weathering due to the microbial amenability of the alkane numerators. Pristane:phytane, phytane:17α,21β-hopane and tricyclic terpanes:hopanes were considered to be the indices best able to distinguish between oils from different origins, based on these results. 17α(H),21β(H)-Hopane:17α(H),21β(H)-norhopane did not adequately distinguish between the respective crude oil samples. Finally, the relationship between heavy oil composition and the index value was investigated. Here, the values of n-alkanes:17α(H),21β(H)-hopane, phytane:17α(H),21β(H)-hopane, and tricyclic terpanes:hopanes decreased as the combined total of polar and asphaltene compounds within oil samples increased. This relationship may be useful in assessing the degradation status of petroleum wastes

  6. Synthesis and use of radio cobaltic EDTA as an extracellular marker in rabbit heart

    Bridge, John H. B.; Bersohn, Malcolm M.; Gonzalez, Frank; BASSINGTHWAIGHTE, JAMES B.

    1982-01-01

    A new γ-labeled marker for extracellular space is the cobaltic form of 58Co-ethylenediaminetetraacetic acid (58Co-EDTA). The cobaltic ion has a much higher affinity for EDTA than the cobaltous ion; it is prepared as a potassium salt, K+(58Co3+-EDTA4−), and is apparently biologically inert. Testing by equilibration in intact rabbits and comparing the myocardial content with that of [14C]sucrose give values of the volume of distribution in the myocardium of 0.294 ± 0.052 ml/g for 58Co-EDTA and ...

  7. Wave motions in the lower thermosphere during the Energy Budget Campaign 1980 from three locations in the northern hemisphere

    Cevolani, G.; Dardi, A.; Formiggini, C. (Consiglio Nazionale delle Ricerche, Bologna (Italy). Ist. FISBAT); Kingsley, S.P.; Muller, H.G. (Sheffield Univ. (UK). Dept. of Physics)

    Simultaneous meteor radar wind observations were made at Budrio (Italy, 45/sup 0/ N), Sheffield (U.K., 53/sup 0/ N) and Stornoway (U.K., 58/sup 0/ N) during the Energy Budget Campaign (EBC), November-December 1980, in the altitude region between 75 and 115 km. Wind results are presented in terms of prevailing components and oscillations of different time scales: Tidal (8, 12 and 24 h), gravity ((3/6) h) and planetary ((2/10) days) waves. The seasonal variation of the prevailing zonal components observed at the three stations in previous years shows the same maxima of Summer and Winter, as well as the equinoctial minima exhibited by the CIRA 1972 model for 50/sup 0/ N. The data show marked tidal activity with the semi-diurnal tide which exceeds in amplitude any other mode in the wind spectra.

  8. Hydrogenation/Dehydrogenation Performances of the MgH2-WS2 Composites

    WANG Jiasheng; ZHANG Wei; CHENG Ying; KE Dandan; HAN Shumin

    2015-01-01

    The hydrogenation/dehydrogenation kinetics and thermodynamic behaviors of the MgH2-WS2 composites were investigated. The TPD (Temperature-Programmed-Desorption) curves showed that the onset dehydrogenation temperature of the MgH2 + 20wt% WS2 composite was 615 K, 58 K lower than that of the pristine MgH2. The kinetic measurements showed that within 21 min, the MgH2 + 20wt% WS2 composite could absorb 2.818wt% at 423 K, and release 4.244 wt% of hydrogen at 623 K, while the hydriding/dehydriding capacity of MgH2 reached only 0.979wt% and 2.319wt% respectively under identical conditions. The improvement of hydrogenation/dehydrogenation performances for the composite was attributed to the co-catalytic effect between the new phases W and MgS which formed during the ball-milling process.

  9. Angular Momentum and Topological Dependence of Kepler's Third Law in the Broucke-Hadjidemetriou-Hénon Family of Periodic Three-Body Orbits

    Janković, Marija R.; Dmitrašinović, V.

    2016-02-01

    We use 57 recently found topological satellites of Broucke-Hadjidemetriou-Hénon's periodic orbits with values of the topological exponent k ranging from k =3 to k =58 to plot the angular momentum L as a function of the period T , with both L and T rescaled to energy E =-0.5 . Upon plotting L (T /k ) we find that all our solutions fall on a curve that is virtually indiscernible by the naked eye from the L (T ) curve for nonsatellite solutions. The standard deviation of the satellite data from the sixth-order polynomial fit to the progenitor data is σ =0.13 . This regularity supports Hénon's 1976 conjecture that the linearly stable Broucke-Hadjidemetriou-Hénon orbits are also perpetually, or Kol'mogorov-Arnol'd-Moser, stable.

    Janković, Marija R

    2016-01-01

    We use 57 recently found topological satellites of Broucke-Hadjidemetriou-Henon's periodic orbits with values of the topological exponent $k$ ranging from $k$ = 3 to $k$ = 58 to plot the angular momentum $L$ as a function of the period $T$, with both $L$ and $T$ rescaled to energy $E=-\\frac12$. Upon plotting $L(T/k)$ we find that all our solutions fall on a curve that is virtually indiscernible by naked eye from the $L(T)$ curve for non-satellite solutions. The standard deviation of the satellite data from the sixth-order polynomial fit to the progenitor data is $\\sigma = 0.13$. This regularity supports Henon's 1976 conjecture that the linearly stable Broucke-Hadjidemetriou-Henon orbits are also perpetually, or Kolmogorov-Arnold-Moser stable.

  11. Methods for reduction of radionuclides incorporated into the body

    Small-scale (laboratories and hospitals) to global radioactive contamination may contribute to incorporation of radionuclides in the living body. In real accidents, many radionuclides are occasionally incorporated simultaneously into the body. Therefore, it is important to know the kinds of radionuclides, chemical form at the incorporation, and presence status and behavior of radionuclides in the body. Because there is interaction between agents for reducing radioactive contamination, the reduction mechanism of radionuclide in the body should be considered when such agents are used in the combination manner. The purpose of this report is to discuss chemical methods for reducing radionuclides that are orally incorporated into the body. These methods are described in terms of dilution, complex production, adsorption, metabolism derangement, and others. I-131, Cs-137, Sr-90, and Ru-106, which are influential radionuclides for the human body, are especially referred to. (N.K.) 58 refs

  12. Two One-Parameter Special Geometries

    Braun, Volker; de la Ossa, Xenia

    2015-01-01

    The special geometries of two recently discovered Calabi-Yau threefolds with $h^{11}=1$ are analyzed in detail. These correspond to the 'minimal three-generation' manifolds with $h^{21}=4$ and the `24-cell' threefolds with $h^{21}=1$. It turns out that the one-dimensional complex structure moduli spaces for these manifolds are both very similar and surprisingly complicated. Both have 6 hyperconifold points and, in addition, there are singularities of the Picard-Fuchs equation where the threefold is smooth but the Yukawa coupling vanishes. Their fundamental periods are the generating functions of lattice walks, and we use this fact to explain why the singularities are all at real values of the complex structure.

    FTIR spectra of monohydric alcohols 1-nonanol (C9H19OH) and 1-decanol (C10H21OH) were registered in the spectral region from 500 cm-1 to 4000 cm-1 at temperatures from -50 to + 25 {\\deg}C for 1-nonanol and +100 {\\deg}C for 1-decanol. Temperature-induced spectra changes were compared for these two alcohols. The authors link the observed changes with the transformations of cluster structure occurring during phase transitions.

  13. Heat resistance of Fe-Al intermetallics in the context of selected heat-resistant and hihg-temperature creep resistant steels

    P. Baranowski

    2009-04-01

    Full Text Available Results are hereby presented of heat-resistance tests of two Fe3Al and FeAl intermetallic phase-based alloys in the context of St41k-typeboiler steel and 50H21G9N4 high-temperature creep resistant steel. It has been ascertained that heat resistance of the 50H21G9N4 steeland of the Fe3Al and FeAl intermetallic phase-based alloys significantly exceeds that of the boiler steel tested in the air atmosphere and the atmosphere of a flue gas with CO, CO2, SiO2 content alike. Improvement of these properties depends of exposure conditions. The largest differences have been observed when the tests were carried out in temperature 1023 K and in the flue gas atmosphere. The differences have been more and more noticeable as the exposition duration extended. A tendency has been also recorded of smaller mass decrements of the Fe3Al and FeAl intermetallic phase-based alloys as compared to the 50H21G9N4 steel.

    Egija Stepina

    2015-10-01

    Full Text Available The title compound, C17H21NO4, consists of substituted Meldrum's acid with a [4-(diethylaminophenyl]methylidene fragment attached to the fifth position. The heterocycle assumes a distorted boat conformation. The planar part of heterocycle is almost coplanar with the benzene ring due to the presence of a long conjugated system in the molecule. This leads to the formation of C—H...O-type intramolecular contacts. As a result of the absence of hydrogen-bond donors in the structure, the crystal packing is controlled by van der Waals forces and weak C—H...O interactions, which associate the molecules into inversion dimers.

    Surveillance registers monitor the prevalence of cerebral palsy and the severity of resulting impairments across time and place. The motor disorders of cerebral palsy can affect children's speech production and limit their intelligibility. We describe the development of a scale to classify children's speech performance for use in cerebral palsy surveillance registers, and its reliability across raters and across time. Speech and language therapists, other healthcare professionals and parents classified the speech of 139 children with cerebral palsy (85 boys, 54 girls; mean age 6.03 years, SD 1.09) from observation and previous knowledge of the children. Another group of health professionals rated children's speech from information in their medical notes. With the exception of parents, raters reclassified children's speech at least four weeks after their initial classification. Raters were asked to rate how easy the scale was to use and how well the scale described the child's speech production using Likert scales. Inter-rater reliability was moderate to substantial (k>.58 for all comparisons). Test-retest reliability was substantial to almost perfect for all groups (k>.68). Over 74% of raters found the scale easy or very easy to use; 66% of parents and over 70% of health care professionals judged the scale to describe children's speech well or very well. We conclude that the Viking Speech Scale is a reliable tool to describe the speech performance of children with cerebral palsy, which can be applied through direct observation of children or through case note review.

  19. Nutritional disorder of lettuce cv. Veronica in nutrient solution with suppressed macronutrients

    Thiago Batista Firmato de Almeida

    2011-06-01

    Full Text Available Lettuce is the most popular of the leafy vegetables. It is known worldwide and its consumption occurs mainly in the natural form. The objective was to evaluate the effect of macronutrient omission on the growth and nutritional status of the lettuce cv. Veronica, and to describe the visual symptoms of nutritional deficiency. The treatments complete consisted of the solution and the individual omission of N, P, K, Ca, Mg and S, under a completely randomized design with three replications. Plants were grown in Hoagland & Arnon, in pots (8L. At 56 days after transplant we evaluated plant height, leaf number, leaf area, SPAD index, dry matter of shoots, roots and whole plant, levels of macronutrients in shoots and roots, and the nature of nutritional disorders. The omission of nutrients affected the growth variables. The nutrients found in lettuce plants from nutrient solution and the complete omission in the shoot were, respectively, N= 23.2 to 9.5, P= 5.4 to 1.3, K= 58,9 to 3.2, Ca= 12.1 to 3.6, Mg= 5.5 to 0.7 and S= 3.2 to 1.5g.kg-1. The omission of macronutrients caused quality losses, since it affected the nutrition of the vegetables and this resulted in morphological changes, reflected as symptoms of deficiency for each nutrient.

  1. Comparison of eight different agars for the recovery of clinically relevant non-O157 Shiga toxin-producing Escherichia coli from baby spinach, cilantro, alfalfa sprouts and raw milk.

    Kase, Julie A; Maounounen-Laasri, Anna; Son, Insook; Lin, Andrew; Hammack, Thomas S

    2015-04-01

    The FDA Bacteriological Analytical Manual (BAM) Chapter 4a recommends several agars for isolating non-O157 Shiga toxin-producing Escherichia coli (STEC); not all have been thoroughly tested for recovering STECs from food. Using E. coli strains representing ten clinically relevant O serogroups (O26, O45, O91, O103, O104, O111, O113, O121, O128, O145) in artificially-contaminated fresh produce--bagged baby spinach, alfalfa sprouts, cilantro, and raw milk--we evaluated the performance of 8 different agars. Performance was highly dependent upon strain used and the presence of inhibitors, but not necessarily dependent on food matrix. Tellurite resistant-negative strains, O91:-, O103:H6, O104:H21, O113:H21, and O128, grew poorly on CHROMagar STEC, Rainbow agar O157, and a modified Rainbow O157 (mRB) agar. Although adding washed sheep's blood to CHROMagar STEC and mRB agars improved overall performance; however, this also reversed the inhibition of non-target bacteria provided by original formulations. Variable colony coloration made selecting colonies from Rainbow agar O157 and mRB agars difficult. Study results support a strategy using inclusive agars (e.g. L-EMB, SHIBAM) in combination with selective agars (R & F E. coli O157:H7, CHROMagar STEC) to allow for recovery of the most STECs while increasing the probability of recovering STEC in high bacterial count matrices.

  2. Triadophilia: A Special Corner in the Landscape

    Candelas, Philip; He, Yang-Hui; Szendroi, Balazs

    2007-01-01

    It is well known that there are a great many apparently consistent vacua of string theory. We draw attention to the fact that there appear to be very few Calabi--Yau manifolds with the Hodge numbers h^{11} and h^{21} both small. Of these, the case (h^{11}, h^{21})=(3,3) corresponds to a manifold on which a three generation heterotic model has recently been constructed. We point out also that there is a very close relation between this manifold and several familiar manifolds including the `three-generation' manifolds with \\chi=-6 that were found by Tian and Yau, and by Schimmrigk, during early investigations. It is an intriguing possibility that we may live in a naturally defined corner of the landscape. The location of these three generation models with respect to a corner of the landscape is so striking that we are led to consider the possibility of transitions between heterotic vacua. The possibility of these transitions, that we here refer to as transgressions, is an old idea that goes back to Witten. Here...

    This paper introduces an index of tax optimality thatmeasures the distance of some current tax structure from the optimal taxstructure in the presence of public goods. In doing so, we derive a [0, 1]number that reveals immediately how far the current tax configurationis from the optimal one and......, thereby, the degree of efficiency of a taxsystem. We call this number the Tax Optimality Index. We show howthe basic method can be altered in order to derive a revenue equivalentuniform tax, which measures the size of the public sector.

    Jiang, L.; Salisbury, F. B.; Campbell, W. F.; Carman, J. G.; Nan, R.

    1998-01-01

    Super-Dwarf wheat plants were grown in growth chambers under 12 treatments with three photoperiods (18 h, 21 h, 24 h) and four carbon dioxide (CO2) levels (360, 1,200, 3,000 and 7,000 micromoles mol-1). Carbon dioxide concentrations affected flower initiation rates of Super-Dwarf wheat. The optimum CO2 level for flower initiation and development was 1,200 micromoles mol-1. Super-optimum CO2 levels delayed flower initiation, but did not decrease final flower bud number per head. Longer photoperiods not only accelerated flower initiation rates, but also decreased deleterious effects of super-optimum CO2. Flower bud size and head length at the same developmental stage were larger under longer photoperiods, but final flower bud number was not affected by photoperiod.

  12. A novel high-performance high-frequency SOI MESFET by the damped electric field

    Orouji, Ali A.; Khayatian, Ahmad; Keshavarzi, Parviz

    2016-06-01

    In this paper, we introduce a novel silicon-on-insulator (SOI) metal-semiconductor field-effect-transistor (MESFET) using the damped electric field (DEF). The proposed structure is geometrically symmetric and compatible with common SOI CMOS fabrication processes. It has two additional oxide regions under the side gates in order to improve DC and RF characteristics of the DEF structure due to changes in the electrical potential, the electrical field distributions, and rearrangement of the charge carriers. Improvement of device performance is investigated by two-dimensional and two-carrier simulation of fundamental parameters such as breakdown voltage (VBR), drain current (ID), output power density (Pmax), transconductance (gm), gate-drain and gate-source capacitances, cut-off frequency (fT), unilateral power gain (U), current gain (h21), maximum available gain (MAG), and minimum noise figure (Fmin). The results show that proposed structure operates with higher performances in comparison with the similar conventional SOI structure.

    2012-01-01

    Full Text Available Assigning autonomy to regency governments in Indonesia has failed to increase regency’s economies.While it increases regency government role in planning and initiating policies, its impact oneconomic development has been insignificant. This stems from the lack of institution’s capacity inorganizing the bulk funds transfer from the central government which leads to inefficiency in resourceallocation. This paper maps these regencies based on their fiscal dependency. This paperalso applies Data Envelopment Analysis to identify the efficient and non efficient regencies in sucha way that the non efficient regencies might use the efficient ones as the benchmark to increase theirefficiency.Keywords: Autonomy, regency government, efficiencyJEL classification numbers: H21, H53, H71, H72

    2008-01-01

    In this paper,the adsorption of Ag+ and hydrated Ag+ cations on clean Si(111)surface were investigated by using cluster(Gaussian 03)and periodic(DMol3)ab initio calculations.Si(111)surface was described with cluster models(Si14H17 and Si22H21)and a four-silicon layer slab with periodic boundary conditions.The effect of basis set superposition error(BSSE)was taken into account by applying the counterpoise correction.The calculated results indicated that the binding energies between hydrated Ag+ cations and clean Si(111)surface are large,suggesting a strong interaction between hydrated Ag+ cations and the semiconductor surface.With the increase of number,water molecules form hydrogen bond network with one another and only one water molecule binds directly to the Ag+ cation.The Ag+ cation in aqueous solution will safely attach to the clean Si(111)surface.

  18. Macrocyclic structures of associated complexes of lithium tetraalkyl borates

    IR spectroscopy and 7Li, 11B NMR were used to study the structure of complex associates [ButOB(OR)3]Li·mHOR (R=Bun, n-C7H15, n-C10H21, n-C13H27; m=0-2) in organic solvents (heptane, cyclohexane-d12) in the concentration range of 0.03-0.07 mol l-1 at 22 deg C. The NMR spectra show magnetic equivalence of all the 7Li and 11B nuclei in the complex associates, that unambiguously confirms their macrocyclic structure. IR spectroscopy data testify to the fact that in the alcoholic solvate Li atom transfers from a strained hexacoordinate state to a more stable tetracoordinate one due to the expansion of intramolecular cycle in each monomer of the polyassociate

  19. Irradiation-induced ordering of a disordered suspension of superheated microspheres

    The 'hot border model' of a suspension of Type-I metastable superconducting grains under irradiation is modified to incorporate heating considerations, and results in the existence of two borders h1 and h2 defined by the minimum and maximum grain volumes of the suspension, respectively. Following a sufficiently long irradiation, the true 'hot border', i.e. the region of the (T, H) phase space in which no superconducting grains exist, should lie only a distance h21 below the phase line: between the two borders, the superconducting grain population is only depleted, and ordered according to decreasing size with increasing distance from the phase line. We provide a partial experimental confirmation of this, and discuss how this modification results in an intrinsic energy calibration for device spectroscopy

    Two new manganese(II) based organic-inorganic hybrid compounds, C11 H21 Cl3 MnN2 (1) and C11 H22 Cl4 MnN2 (2), with prominent photoluminescence and dielectric properties were synthesized by solvent modulation. Compound 1 with novel trigonal bipyramidal geometry exhibits bright red luminescence with a lifetime of 2.47 ms and high quantum yield of 35.8 %. Compound 2 with tetrahedral geometry displays intense long-lived (1.54 ms) green light emission with higher quantum yield of 92.3 %, accompanied by reversible solid-state phase transition at 170 K and a distinct switchable dielectric property. The better performance of 2 results from the structure, including a discrete organic cation moiety and inorganic metal anion framework, which gives the cations large freedom of motion. PMID:26864910

  9. Biochemical studies on certain biologically active nitrogenous compounds

    Certain biologically active nitrogenous compounds such as alkaloids are widely distributed in many wild and medicinal plants such as peganum harmala L. (Phycophyllaceae). However, less literature cited on the natural compounds was extracted from the aerial parts of this plant; therefore this study was conducted on harmal leaves using several solvents. Data indicated that methanol extract was the inhibitoriest effect against some pathogenic bacteria, particularly Streptococcus pyogenus. Chromatographic separation illustrated that presence of four compounds; the most active one was the third compound (3). Elementary analysis (C, H, N) revealed that the primary chemical structure of the active antibacterial compound (C3) was: C17 H21 N3 O7 S with molecular weight 411. Spectroscopic analysis proved that coninical structure was = 1- thioformyl, 8?- D glucoperanoside- Bis- 2, 3 dihydroisopyridino pyrrol.

  19. Mechanism of 2-oxoglutarate signaling by the Synechococcus elongatus PII signal transduction protein.

    Fokina, Oleksandra; Chellamuthu, Vasuki-Ranjani; Forchhammer, Karl; Zeth, Kornelius

    2010-11-16

    P(II) proteins control key processes of nitrogen metabolism in bacteria, archaea, and plants in response to the central metabolites ATP, ADP, and 2-oxoglutarate (2-OG), signaling cellular energy and carbon and nitrogen abundance. This metabolic information is integrated by P(II) and transmitted to regulatory targets (key enzymes, transporters, and transcription factors), modulating their activity. In oxygenic phototrophs, the controlling enzyme of arginine synthesis, N-acetyl-glutamate kinase (NAGK), is a major P(II) target, whose activity responds to 2-OG via P(II). Here we show structures of the Synechococcus elongatus P(II) protein in complex with ATP, Mg(2+), and 2-OG, which clarify how 2-OG affects P(II)-NAGK interaction. P(II) trimers with all three sites fully occupied were obtained as well as structures with one or two 2-OG molecules per P(II) trimer. These structures identify the site of 2-OG located in the vicinity between the subunit clefts and the base of the T loop. The 2-OG is bound to a Mg(2+) ion, which is coordinated by three phosphates of ATP, and by ionic interactions with the highly conserved residues K58 and Q39 together with B- and T-loop backbone interactions. These interactions impose a unique T-loop conformation that affects the interactions with the P(II) target. Structures of P(II) trimers with one or two bound 2-OG molecules reveal the basis for anticooperative 2-OG binding and shed light on the intersubunit signaling mechanism by which P(II) senses effectors in a wide range of concentrations.

    Mining of nutrients from soil is a major problem in developing countries causing soil degradation and threaten long-term food production. The present study attempts to apply NUTrient MONitoring (NUTMON) model for carrying out nutrient budgeting to assess the stocks and flows of nitrogen (N), phosphorus (P), and potassium (K) in defined geographical unit based on the inputs, viz., mineral fertilizers, manures, atmospheric deposition, and sedimentation, and outputs, viz., harvested crop produces, residues, leaching, denitrification, and erosion losses. The study area covers Coimbatore and Erode Districts, which are potential agricultural areas in western agro-ecological zone of Tamil Nadu, India. The calculated nutrient balances for both the districts at district scale, using NUTMON methodology, were negative for nitrogen (N -3.3 and -10.1 kg ha(-1)) and potassium (K -58.6 and -9.8 kg ha(-1)) and positive for phosphorus (P +14.5 and 20.5 kg ha(-1)). Soil nutrient pool has to adjust the negative balance of N and K; there will be an expected mining of nutrient from the soil reserve. A strategy was attempted for deriving the fertilizer recommendation using Decision Support System for Integrated Fertilizer Recommendation (DSSIFER) to offset the mining in selected farms. The results showed that when DSSIFER recommended fertilizers are applied to crops, the nutrient balance was positive. NUTMON-Toolbox with DSSIFER would serve the purpose on enhancing soil fertility, productivity, and sustainability. The management options to mitigate nutrient mining with an integrated system approach are also discussed. PMID:27021693

    Electrochemical transformation of CO2 into functional materials or fuels (i.e., carbon, CO) in high temperature molten salts has been demonstrated as a promising way of carbon capture, utilisation and storage (CCUS) in recent years. In a view of continuous operation, the electrolysis process should match very well with the CO2 absorption kinetics. At the same time, in consideration of the energy efficiency, a molten salt electrochemical cell running at lower temperature is more beneficial to a process powered by the fluctuating renewable electricity from solar/wind farms. Ternary carbonates (Li : Na : K = 43.5 : 31.5 : 25.0) and binary chlorides (Li : K = 58.5 : 41.5), two typical kinds of eutectic melt with low melting points and a wide electrochemical potential window, could be the ideal supporting electrolyte for the molten salt CO2 capture and electro-transformation (MSCC-ET) process. In this work, the CO2 absorption behaviour in Li2O/CaO containing carbonates and chlorides were investigated on a home-made gas absorption testing system. The electrode processes as well as the morphology and properties of carbon obtained in different salts are compared to each other. It was found that the composition of molten salts significantly affects the absorption of CO2, electrode processes and performance of the product. Furthermore, the relationship between the absorption and electro-transformation kinetics are discussed based on the findings. PMID:27193751

  2. In situ-ATR-FTIR analysis on the uptake and release of streptomycin from polyelectrolyte complex layers

    Torger, B.; Müller, M.

    2013-03-01

    In-situ ATR-FTIR spectroscopy and line shape analysis of the diagnostic spectral region was used to quantify the bound amount and release of the antibiotic streptomycin (STRP) at polyelectrolyte (PEL) multilayers (PEM) of poly(ethyleneimine) (PEI) and poly(acrylic acid) (PAA) or PEI and sodium alginate (ALG). Unlike common concepts based on the drug enrichment of the release medium, this analytical concept allowed to measure quantitatively the drug depletion in the delivery matrix. The measured kinetic in situ ATR-FTIR data were analysed by a modified Korsmeyer-Peppas equation based on two characteristic release parameters k and n. As main experimental parameters the number of PEL layers (adsorption steps) z and the STRP/PEL ratio were varied. For z = 8 the STRP/PEL ratio showed the most significant influence on release kinetics, whereby for STRP/PEL = 1:25 slowest (n = 0.77) and lowest (k = 21.4%) and for STRP/PEL = 1:5 most rapid (n = 0.30) and highest (k = 58.6%) drug releases were found. PEM-PEI/ALG-8 (STRP/PEL = 1:5) revealed slower release rates (n = 0.58) and lower released STRP amounts (k = 17.1%) compared to PEI/PAA. UV-VIS data on time dependent STRP enrichment of the release medium showed a similar trend compared to respective ATR-FTIR data on STRP depletion in PEM. Released amounts of around 1-2 mg from the herein introduced PEM films could be determined. The introduced analytical concept will be used as screening tool for other drugs, drug eluting films and bone substituting materials.

  3. Functional studies of the gene slr2049 from Synechocystis sp. PCC6803 and its site-directed mutation.

    2015-06-01

    Phycobiliprotein is a homologous family of light-harvesting chromoproteins existing in cyanobacteria, red algae and cryptophytes. Phycobiliprotein is made up of phycobilin and its corresponding apophycobiliprotein, and they are covalently linked by the thioether bond with the bilin lyase. Using the software BLAST, we have found gene slr2049 in Synechocystis sp. PCC6803 homologous to the biliprotein lyase gene cpeS. This paper investigates the protein expressed by gene slr2049 to find the enzymatic activity characteristics. We cloned slr2049 and its related genes cpcB, ho1, and pcyA which are linked with the synthesis of phycocyanin. Special amino acid mutagenesis was performed on slr2049 to construct eight mutants slr2049 (H21S), slr2049 (L23S), slr2049 (A24S), slr2049 (F25S), slr2049 (W72L), slr2049 (G84S), slr2049 (R107S) and slr2049 (Y124S). These mutants were ligated with vectors pEDFDuet-1 and pET-23a to construct pCDF-cpcB-slr2049 wild-type, pCDF-cpcB-slr2049 mutants and pET-ho1-pcyA, for the purpose of protein expression and analysis. The results showed that the wild-type and mutants slr2049 (H21S), slr2049 (L23S), slr2049 (F25S), slr2049 (W72L), slr2049 (G84S), and slr2049 (Y124S) can catalyze CpcB to couple on PCB correctly and the products have unique spectral characteristics. However mutants slr2049 (A24S) and slr2049 (R107S) have no spectral characteristics. Thus, it is suggested that alanine at position 24 and arginine at position 107 are the active sites.

Uranyl sulfate solutions of 0.005% concentration were used for the investigation. The solution pH was varied in the range 0.5-4.0. The sulfate-ion concentration was 0.1 g-ion/liter. The collectors (the surfactants listed above) were introduced into the uranium-containing test solutions in the form of 0.4% aqueous solutions, in the stoichiometric amounts required for binding UO2(SO4)34- anions. Flotation treatment of the solutions was continued for 20 min in the apparatus described in previous reports. The uranium and collector contents in the solutions were determined by standard methods. The zeta potentials of the sublate particles were determined electrophoretically

    A simple, economical, and green approach to the synthesis of 5,5‧-((2,4-dichlorophenyl)methylene)bis(1,3-dimethylpyrimidine-2,4,6(1H,3H,5H)-trione) 4 using a tandem Aldol condensation-Michael addition process in aqueous diethylamine medium was described. The 3D structure of the latter was confirmed by single-crystal X-ray structure determination. The molecular structure of the titled compound was calculated using DFT B3LYP/6-311G(d,p) method. The calculated geometric parameters are in good agreement with the experimental data obtained from our reported X-ay structure. The two pyrimidinetrione rings have C16 and C20 atoms deviated significantly from the ring plane. The electronic spectra of the studied compound have been calculated using the TD-DFT method. The longest wavelength band (257.8 nm, f = 0.0276) occurs due to H → L (86%) transition. The 1H and 13C NMR calculated chemical shifts using GIAO method showed good correlation with the experimental data. The molecular electrostatic potential (MEP) showed that the most reactive sites for electrophilic and nucleophilic attacks are the carbonyl oxygen (O5) and the H21 atoms, respectively. The NBO calculations were performed to predict the natural atomic charges at the different atomic sites and to study the different intramolecular charge transfer (ICT) interactions occurring in the studied system. Interestingly, there is some delocalization of electron densities from the occupied σ-type NBO of the C20sbnd H21 to the unoccupied π∗-NBO of the two adjacent carbonyl groups.

  6. An experimental study of the mechanism of the replacement of magnetite by pyrite up to 300 °C

    2010-10-01

    We present the results of an experimental study into the sulfidation of magnetite to form pyrite/marcasite under hydrothermal conditions (90-300 °C, vapor saturated pressures), a process associated with gold deposition in a number of ore deposits. The formation of pyrite/marcasite was studied as a function of reaction time, temperature, pH, sulfide concentration, solid-weight-to-fluid-volume ratio, and geometric surface area of magnetite in polytetrafluoroethylene-lined autoclaves (PTFE) and a titanium and stainless steel flow-through cell. Marcasite was formed only at pH 21°C 2 and formed even under basic conditions (up to pH 21°C 12-13). Marcasite formation was favored at higher temperatures. Fine-grained pyrrhotite formed in the initial stage of the reaction together with pyrite in some experiments with large surface area of magnetite (grain size PTFE liner, which is consistent with pyrite crystallizing from solution. The mechanism of the reaction is that of a dissolution-reprecipitation reaction with the precipitation of pyrite being the rate-limiting step relative to magnetite dissolution under mildly acidic conditions (e.g., pH 155°C 4.42). The experimental results are in good agreement with sulfide phase assemblage and textures reported from sulfidized Banded Iron Formations: pyrite, marcasite and pyrrhotite have been found to exist or co-exist in different sulfidized Banded Iron Formations, and the microtextures show no evidence of sub-μm-scale pseudomorphism of magnetite by pyrite.

  7. Wave motions in the lower thermosphere during the energy budget campaign 1980 from three locations in the northern hemisphere

    Cevolani, G.; Dardi, A.; Formiggini, C. (Consiglio Nazionale delle Ricerche, Bologna (Italy)); Kingsley, S.P.; Muller, H.G. (Sheffield Univ. (UK). Dept. of Physics)

    Simultaneous meteor radar wind observations were made at Budrio (Italy,45 deg N), Sheffield (U.K.,53 deg N) and Stornoway (U.K.,58 deg N) during the Energy Budget Campaign (EBC), November-December 1980, in the altitude region between 75 and 115 km. Wind results are presented in terms of prevailing components an oscillations of different time scales: tidal (8,12 and 24 h), gravity ((3/6)h) and planetary ((2/10) days) waves. The seasonal variation of the prevailing zonal components observed at the three stations in previous years shows the same maxima of Summer and Winter, as well as the equinactial minima exhibited by the CIRA 19972 model for 50 deg N. The data show marked tidal activity with the semi-diurnal tide which exceeds in amplitude any other mode in the wind spectra. Tidal amplitudes recorded at Budrio appear more significantly lower than those recorded at Sheffield and Stornoway. Variations of the amplitude of maxima of the semi-diurnal oscillation relative to the Budrio and Sheffield data show time scales generally greater than 5 days throughout the recording period. The diurnal and terdiurnal tides represent a small part of the total wind energy in the meteor zone and exhibit phases which disagree strongly at the quoted stations. The scatter in the hourly data is representative of small-scale wind disturbances due to internal gravity waves: at Budrio, by using the MEM method for individual day's data (November 23-24, 28-29, 1980), gravity waves with vertical wave-lengths of (20/45) km, periods of 3.5, 4.5 and 6 h, and amplitudes of the order of 10 ms/sup -1/ have been observed. Long-period oscillations with periods in the (2/10) day time interval have been identified in the wind patterns at Budrio and Sheffield, but the presence of planetary waves of quasi-2-day period was less significant than during a previous Summer 1980 run carried out at the same stations.

  8. Palaeomagnetic and rock magnetic studies on the dykes of Goa, west coast of Indian Precambrian Shield

    Patil, S. K.; Rao, D. R. K.

    2002-11-01

    Detailed alternating field (AF) and thermal demagnetization techniques on 120 samples belonging to 10 dykes of the Goa region along the west coast of the Indian Precambrian Shield, have yielded characteristic remanent magnetization (ChRM) directions from 9 dykes of which 6 dykes exhibited a reverse magnetic polarity direction ( D=150°, I=44.30°, k=58, α95=5.8, N=6 dykes), while 3 dykes exhibited normal polarity D=351°, I=-50°, k=21, α95=14.9, N=3 dykes) direction. The remaining 1 dyke has shown stable direction, but with a strong overprint of the present earth field (PEF) direction, which could not be removed by either AF or thermal cleaning techniques. A Palaeomagnetic pole, computed by averaging the VGPs of 9 dykes is situated at 41.2°N 78.1°W ( N=9 dykes; A95=9.81°), which is close to that of the Deccan super pole (36.9°N, 78.8°W), suggesting that the dykes in the Goa region are related to the Deccan basaltic eruptions. Recently published 40Ar/ 39Ar dating on the normal polarity dykes of the studied area have assigned the ages as 62.8±0.2 Ma. These results demonstrate that the Deccan magnetism continued to affect western India for at least 1-2 Ma after the peak Deccan eruption during the K- T boundary. On the basis of published geological and geochemical information along with our Palaeomagnetic results, these intrusive bodies could be attributed as the feeders for the uppermost formations of Wai subgroup of the Western Ghat Deccan basalts, or to the major geodynamic events such as the opening of the Arabian Sea and the rifting of the Seychelles-Mascarene oceanic plateau, which occurred soon after the cessation of the Deccan volcanism. Rock magnetic experiments such as the Lowrie-Fuller test along with low-temperature magnetic susceptibility and isothermal remanent magnetization (IRM) measurements have identified single domain (SD) type titano-magnetite as the major characteristic remanent magnetization carrying magnetic mineral in the dyke samples.

  9. Measurement and Analysis of Specific Activities of 238U, 232Th,226Ra, 40K and 137Cs in Soil Samples from Phatthalung Province (Thailand) using Gamma Ray Spectrometry

    Full text: Specific activity of natural (238U, 232Th, 226Ra and 40K ) and anthropogenic radionuclide (137Cs) in 109 soil samples collected from 11 districts in Phathalung province have been measured and analyzed. Experimental results were obtained by using a high purity germanium (HPGe) detector and gamma spectrometry analysis system at Nuclear and Material Physics laboratory in Department of Physics Faculty of Science Thaksin University Songkhla Campus. Gamma ray radioactive standard sources 60Co, 137Cs and 133Ba were used to calibrate the measurement system. The KCl and two reference materials (RGU-1 and RGTh-1) obtained from the International Atomic Energy Agency were also used to analyze and compute the 40K, 238U (or 226Ra) and 232Th specific activity in all soil samples. The IAEA/SL-2 was also used to evaluate the specific activity of 137Cs in all soil samples. The measuring time of each sample was 10,800 seconds. It was found that specific activity ranged from 148.17 to 11276.78 Bq/kg for 40K, 58.29 to 518.45 Bq/kg for 226Ra, 8.40 to 236.19 Bq/kg for 232Th and 0.00 tp 12.39 Bq/kg for 137Cs with mean values of 3573.35 ± 203.89 Bq/kg, 135.89 ± 6.71 Bq/kg, 76.34 ± 5.32 Bq/kg and 1.05 ± 0.70 Bq/kg respectively. Furthermore, absorbed dose rate in air (D), radium equivalent activity (Raeq), external hazard index (Hex), and annual effective dose rate (AEDout) of this area were also evaluated by using the mean values of specific activities of the 40K, 226Ra and 232Th. Moreover, the experimental results were also compared with Office of Atoms for Peace (OAP) research data, Thailand and global radioactivity measurement and evaluations. The radioactive contour maps of specific activities of natural and anthropogenic radionuclides from this study were created by using the program ArcGis Version 9.2

  10. Construction of an ''intelligent'' trigger system for kaons and study of the K+ production in the system Ne+NaF at 1.0 GeV/u

    The technical part of this thesis describes the construction, the properties, and the experience from the application of an intelligent software trigger for the experiments on the production of positive kaons at the kaon spectrometer. The software trigger was applied in several beam-times. An essiential improvement in the yield of the registrated kaons was reached. The realization ensued by the application of standard components and represents a flexible and cost-efficient solution. The physical part of this thesis deals with the measurement of the double-differential cross section for positive kaons, positive pions, and protons in the system Ne+NaF at 1.0 GeV/u beam energy in the laboratory-angle range ofΘlab=44 ±4 . the beam energy of 1.0 GeV/u lies below the threshold energy for the production of positive kaons in the collision of two free nucleons of Ebeamthreshold=1.58 GeV. The momentum spectra of kaons and pions in the laboratory-momentum range from 270 MeV/c to 1140 MeV/c can be well described by a Boltzmann distribution in the c. m. system. The steepness parameter of the Boltzmann distributions amount to 64 MeV for kaons and 58 MeV for pions. The momentum-integrates cross section were determined from the extrapolation of the fitted Boltzmann distributions to: (dσ/dΩlab)ΔΩlabK+=58.6±9.2 μb/sr and (dσ/dΩlab)ΔΩlabπ+=169±17 mb/sr. The total cross sections were calculated under the assumption of the isotropy in the c. m. system from the fitted distributions: σ0K+=335±52 μb and σ0π+=939±96 mb. The mass dependence of the meson production cross sections in the symmetrc collisional system Ne+NaF was studied and compared with the results of the study of the heavy collisional system Au+Au

    T R Lenka; A K Panda

    2012-07-01

    In this paper, a new gate-recessed AlGaN/GaN-based high electron mobility transistor (HEMT) on SiC substrate is proposed and its DC as well as microwave characteristics are discussed for Si3N4 and SiO2 passivation layers using technology computer aided design (TCAD). THe two-dimensional electron gas (2DEG) transport properties are discussed by solving Schödinger and Poison equations self-consistently resulting in various subbands having electron eigenvalues. From DC characteristics, the saturation drain currents are measured to be 600 mA/mm and 550 mA/mm for Si3N4 and SiO2 passivation layers respectively. Apart from DC, small-signal AC analysis has been done using two-port network for various microwwave parameters. The extrinsic transconductance parameters are measured to be 131.7 mS/mm at a gate voltage of $V_{gs} = -0.35$ V and 114.6 mS/mm at a gate voltage of $V_{gs} = -0.4$ V for Si3N4 and SiO2 passivation layers respectively. The current gain cut-off frequencies $(f_{t})$ are measured t be 27.1 GHz and 23.97 GHz in unit-gain-point method at a gate voltage of -0.4 V for Si3N4 and SiO2 passivation layers respectively. Similarly, the power gain cut-off frequencied $(f_{max})$ are measured to be 41 GHz and 38.5 GHz in unit-gain-point method at a gate voltage of -0.1 V for Si3N4 and SiO2 passivation layers respectively. Furthermore, the maximum frequency of oscillation or unit power gain (MUG = 1) cut-off frequencies for Si3N4 and SiO2 passivation layers are measured to be 32 GHz and 28 GHz respectively from MUG curves and the unit current gain, $|h_{21}| = 1$ cut-off frequencies are measured to be 140 GHz and 75 GHz for Si3N4 and SiO2 passivation layers respectively from the $abs |h_{21}|$ curves. HEMT with Si3N4 passivation layer giver better results than HEMT with SiO2 passivation layer.

  12. Preparation of Monoclonal Antibody and Development of Enzyme-linked Immunosorbent Assay Specific for Escherichia coli O157 in Foods

    2005-01-01

    Objective To prepare monoclonal antibodies (Mab) and antisera specific for Escherichia coli (E.coli) O157, and to develop a sandwich enzyme-linked immunosorbent assay (ELISA) to detect E.coli O157 in foods. Methods Spleen cells from BALB/c mice immunized with the somatic antigen of E.coli O157:H7 were fused with murine Sp2/0 myeloma cells. The hybridoma cell line specific for E.coli O157 was established after having been subcloned. Antisera specific for E.coli O157 was prepared by intravenous injection into New Zealand rabbits with a stain of E.coli O157:H7. The sandwich ELISA was developed with the polyclonal antibody as the capture antibody and the Mab 3A5 as the detection antibody. The inoculated ground poultry meat and pasteurized milk were tested to confirm efficiency of the method. Results Mab 3A5 specific for E.coli O157 and O113:H21 belonged to subtype IgM. The ascetic titers of the antibody was 1:1×106. No cross-reactivity of the Mab was observed with strains of Salmonella spp, Yersinia enterocolitica, Shigella dysenteriae, etc. The purified polyclonal antibody had a titer of 1:1×105 with E.coli O157. The detection limit of this sandwich ELISA was 103-104 cfu E.coli O157/mL in pure culture with a high specificity, which was characterized by every non-O157 strain with negative response. With 10h enrichment procedure, E.coli O157:H7 recovered well from inoculated ground poultry meat and pasteurized milk at levels of 0.1 cfu/g and 0.1 cfu/mL. Conclusion Mab 3A5 specific for E.coli O157 and O113:H21 can be produced by immunizing BALB/c mice with a strain of E.coli O157:H7. Then a sandwich ELISA can be developed with the polyclonal antibody as the capture antibody and the Mab 3A5 as the detection antibody. The method is proved to be a sensitive and specific technique to detect low number of E.coli O157 in food.

    2016-04-15

    The chemical compositions of PM2.5 including OC, EC, water soluble ions, elements, and organic components such as polycyclic aromatic hydrocarbons (PAHs), hopanes, and steranes, emitted in Wuzushan (WZS) and Kuixinglou (KXL) tunnels were determined. WZS tunnel is a major route for diesel vehicles traveling, while KXL tunnel has limited to diesel vehicles. The results showed that the proportions of the different constituents of PM2.5 in the Wuzushan (WZS) tunnel were OC (27.7%), EC (32.1%), elements (13.9%), and water soluble ions (9.2%). Whereas the chemical profile of PM2.5 in the Kuixinglou (KXL) tunnel was OC (17.7%), EC (10.4%), elements (8.90%), and water soluble ions (8.87%). The emission factors (EFs) of PM2.5 and proportions of SO4(2-) and Pb were decreased by vehicle emission standards and fuel quality policy in China, and the higher molecular weight PAHs (4+5+6 rings) were more abundant than the lower molecular weight PAHs (2+3 rings) in the two tunnels. The proportions of 17A(H)-21B(H)-30-Norhopane and 17A(H)-21B(H)-Hopane in the hopane and sterane were not dependent on the vehicles types. In addition, specific composition profiles for PM2.5 from gasoline-fueled vehicles (GV) and diesel-fueled vehicles (DV) emissions were drafted, which indicated that OC (0.974mg·veh(-1)·km(-1)) was the most abundant component in PM2.5, followed by Fe, Cl(-), and Mg for GV. The relative proportions of the different constituents in the PM2.5 for DV were EC (35.9%), OC (27.2%), elements (12.8%), and water soluble ions (11.7%). Both the PM2.5 EFs and EC proportions in DV were higher than those in GV, and the HMW PAHs were the dominant PAHs for both GV and DV. The PM2.5 emissions from the vehicles in Yantai were 581±513tons to 1353±1197tons for GV, and 19,627±2477tons to 23,042±2887tons for DV, respectively. PMID:26808403

    The efficiency of different bioremediation products (nutrients, microorganisms and biodiesel) was tested using tiles located in both the supra-littoral and intertidal zones of a beach that was affected by the heavy oil spill of the Prestige. Neither nutrients nor microorganisms meant an improvement with respect to the natural processes. The addition of biodiesel improved the appearance of the treated tiles and apparently accelerated the degradation of the aliphatic and aromatic fractions of the residual fuel oil. Nevertheless, PAHs degradation was similar and very high in all the treatments (80-85% after 60 days). On the other hand, the evolution with time of the amount of vanadium was similar to that of 17{alpha}(H),21{beta}(H)-hopane, so it was concluded that vanadium could also be used to estimate the extent of oil degradation in the field. These results also suggested that the residual fuel oil mineralization was very low throughout 1 year in all the treatments. Moreover, the increase of the oxygen content of the residual oil from around 1% till 4-8% indicated that the partial oxidation of hydrocarbons took place, and that the hydrocarbon oxidation products accumulated in the polar fractions. In general, the results pointed out that bioremediation techniques were not suitable for the recovery of shores affected by heavy oil spills.

  17. Limits on the Size and Orbit Distribution of Main Belt Comets

    Sonnett, S; Jedicke, R; Masiero, J

    2011-01-01

    The seven known main belt comets (MBCs) have orbital characteristics of main belt asteroids yet exhibit dust ejection like comets. In order to constrain their physical and orbital properties we searched the Thousand Asteroid Light Curve Survey (TALCS; Masiero et al. 2009) for additional candidates using two diagnostics: tail and coma detection. This was the most sensitive MBC survey effort to date, extending the search from MBCs with H~18 (D~1 km) to H~21 (D~150 m). We fit each of the 924 TALCS objects to a PSF model incorporating both a coma and nuclear component to measure the fractional contribution of the coma to the total surface brightness. We determined the significance of the coma detection using the same algorithm on a sample of comparable null detections. We did not identify any MBC candidates with this technique to a sensitivity limit on the order of cometary mass loss rate of about 0.1 kg/s. Our tail detection algorithm identified statistically significant flux in a segmented annulus around the ca...

  18. XMM-Newton and UV Detection of OVIII and Broad HI absorption towards PKS 0558-504: a possible WHIM filament

    Nicastro, F; Fields, D; Conciatore, M L; Zappacosta, L; Elvis, M; Mathur, S; Papadakis, I

    2009-01-01

    We present the first likely X-ray detection associated with Broad HI Ly$\\beta$ (BLB) and Ly$\\alpha$ (BLA) absorbers, consistent with being a WHIM filament. The absorber lies along the line of sight to the nearby ($z=0.1372$) Seyfert 1 galaxy PKS 0558-504. The X-ray absorber is marginally detected in two independent XMM-Newton spectra of PKS 0558-504, with a combined single line statistical significance of 2.8$\\sigma$ (2.7$\\sigma$ and 1.2$\\sigma$ in the two spectra, respectively). When fitted with our self-consistent hybrid-photoionization WHIM models, the combined XMM-{\\em Newton} spectrum is consistent with the presence of an OVIII K$\\alpha$ absorber at $z=(0.117 \\pm 0.001)$, with log$T=6.56_{-0.17}^{+0.19}$ K, and logN$_H=(21.5 \\pm 0.3) (Z/Z_{0.01\\odot})^{-1}$ cm$^{-2}$. The lack of detection of associated OVI in the archival FUSE spectrum of PKS 0558-504, allows us to infer a tighter lower limit on the temperature, of log$T>6.52$ K (at 1$\\sigma$). The statistical sigificance of this single X-ray detection ...

  19. Mirror Symmetry of Minimal Calabi-Yau Manifolds

    Kawada, Hideyuki; Suzuki, Hisao

    2015-01-01

    We perform the mirror transformations of Calabi-Yau manifolds with one moduli whose Hodge numbers $(h^{11}, h^{21})$ are minimally small. Since the difference of Hodge numbers is the generation of matter fields in superstring theories made of compactifications, minimal Hodge numbers of the model of phenomenological interest are (1,4). Genuine minimal Calabi-Yau manifold which has least degrees of freedom for K\\"ahler and complex deformation is (1,1) model. With help of {\\it Mathematica} and {\\it Maple}, we derive Picard-Fuchs equations for periods, and determine their monodromy behaviors completely such that all monodromy matrices are consistent in the mirror prescription of the model (1,4), (1,3) and (1,1). We also discuss to find the description for each mirror of (1,3) and (1,1) by combining invariant polynomials of variety on which (1,5) model is defined. The genus 0 instanton numbers coming from mirror transformations in above models look reasonable. We propose the weighted discriminant for genus 1 insta...

  20. Photoinduced Charge Separation in Porphyrin Ion Pairs.

    Natali, Mirco; Scandola, Franco

    2016-03-10

    Ion pairs between porphyrin-type compounds have been successfully employed for spectral sensitization of semiconductor surfaces and for the preparation of collective binary ionic materials for photonic and (photo)catalytic applications. The understanding of the photophysical processes occurring within ion-paired porphyrin dimers is thus of remarkable importance for the optimization and improvement of such systems. Herein the ion-pair species formed between ZnTMePyP(4+) (Zn1) or H2TMePyP(4+) (H21) and ZnTPPS(4-) (Zn2) or H2TPPS(4-) (H22) in a variety of solvent mixtures are characterized and their photophysics thoroughly investigated by time-resolved techniques. In all the systems studied, very fast and efficient photoinduced charge separation is observed, with the cationic porphyrin being reduced and the anionic one oxidized. Interestingly, despite the very short charge separation distance, the lifetime for charge recombination, depending on the energy gap, can extend into the nanosecond time domain, showing great potential for the utilization of this molecular design within energy conversion schemes.

    2004-01-01

    Mesoporous vanadia-silica catalysts have been prepared by three different sol-gel procedures using tetraethylorthosilicate (TEOS), vanadyl acetylacetonate (VAA), or VOCl3 and in some cases quaternary ammonium salts ((CH3)(3)C14H29N+Br- or (C10H21)(4)N+Br-) as surfactants. According to procedure A......, TEOS and VAA were concomitantly hydrolyzed, in procedure B TEOS was prehydrolized and vanadium precursor was added to the silica sol, and in procedure C both TEOS and vanadium precursors were separately prehydrolized. The sol-gel procedures were controlled by checking the effect of the hydrolysis p...... calcination of the V/Cs catalysts vanadia is dissolved in a sulfate containing molten salt. The activity of these catalysts for the oxidation of SO2 was tested in a gas containing 2% SO2, 19% O-2, 79% N-2 in the temperature range 523-823 K. Similar experiments with gases containing 10% H2O in the feed or with...

    The asymmetric unit of the title mol-ecular salt, C17H21N2O2S(+)·C14H15O7P2 (-), comprises two cations and two anions. Each cation features an intra-molecular N-H⋯O hydrogen bond, which closes an S(6) ring; in each case the hydro-pyridine ring adopts a half-chair conformation. In the anions, the dihedral angles between the aromatic rings are 64.1 (2) and 54.9 (2)°. In each case, the diphosphate groups are close to eclipsed [C-P⋯P-C pseudo-torsion angles = 11.6 (2) and -19.3 (2)°]. One of the meth-oxy groups in each anion is disordered over two orientations in a 0.539 (18):0.461 (18) ratio in one anion and 0.82 (2):0.18 (2) in the other. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the components into [100] chains. Numerous C-H⋯O inter-actions cross-link the chains into a three-dimensional network. PMID:26870570

A weak intramolecular C—H...N contact may influence the molecular conformation. The crystal structure is stabilized by C—H...π contacts involving the phenyl and pyrazole rings, and by π–π stacking interactions involving the pyridine and benzene rings [centroid–centroid distance = 3.5972 (10 Å].

    We report the probable identification of the X-ray counterpart to the gamma-ray pulsar PSR J2021+4026 using imaging with the Chandra X-ray Observatory ACIS and timing analysis with the Fermi satellite. Given the statistical and systematic errors, the positions determined by both satellites are coincident. The X-ray source position is R.A. 20h21m30.733s, Decl. +40 deg 26 min 46.04sec (J2000) with an estimated uncertainty of 1.3 arsec combined statistical and systematic error. Moreover, both the X-ray to gamma-ray and the X-ray to optical flux ratios are sensible assuming a neutron star origin for the X-ray flux. The X-ray source has no cataloged infrared-to-visible counterpart and, through new observations, we set upper limits to its optical emission of i' >23.0 mag and r' > 25.2mag. The source exhibits an X-ray spectrum with most likely both a powerlaw and a thermal component. We also report on the X-ray and visible light properties of the 43 other sources detected in our Chandra observation.

    X-ray observations have unveiled the existence of a family of radio-quiet Isolated Neutron Stars whose X-ray emission is purely thermal, hence dubbed X-ray Dim Isolated Neutron Stars (XDINSs). While optical observations have allowed to relate the thermal emission to the neutron star cooling and to build the neutron star surface thermal map, IR observations are critical to pinpoint a spectral turnover produced by a so far unseen magnetospheric component, or by the presence of a fallback disk. The detection of such a turnover can provide further evidence of a link between this class of isolated neutron stars and the magnetars, which show a distinctive spectral flattening in the IR. Here we present the deepest IR observations ever of five XDINSs, which we use to constrain a spectral turnover in the IR and the presence of a fallback disk. The data are obtained using the ISAAC instrument at the VLT. For none of our targets it was possible to identify the IR counterpart down to limiting magnitudes H = 21.5 - 22.9. ...

    Full Text Available The title compounds consist of a bornane skeleton with attached acetamide, C12H21NO (±-(1 {systematic name: (±-N-[(1RS,2RS,4RS-1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl]acetamide}, and chloroacetamide, C12H20ClNO (±-(2 {systematic name: (±-2-chloro-N-[(1RS,2RS,4RS-1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl]acetamide}, functionalities to the 2-exo-position. The crystal structure of the first monoclinic polymorph of (±-(1 has been reported previously [Ung et al. (2014. Monatsh. Chem. 145, 983–992]. Compound (±-(1 crystallizes in the space group P21/n with two independent molecules in the asymmetric unit, in contrast to the above-mentioned polymorph which crystallized in the space group C2/c with one molecule in the asymmetric unit. In the title compounds, the bicyclic bornane moieties have normal geometries. In the crystals of both compounds, molecules are linked by N—H...O hydrogen bonds, reinforced by C—H...O contacts, forming trans-amide chains propagating along the a-axis direction. In the case of compound (±-(1, neighbouring chains are linked by further C—H...O contacts, forming double-chain ribbons along [100].

  7. Evaluation of biodiesel as bioremediation agent for the treatment of the shore affected by the heavy oil spill of the Prestige

    The efficiency of different bioremediation products (nutrients, microorganisms and biodiesel) was tested using tiles located in both the supra-littoral and intertidal zones of a beach that was affected by the heavy oil spill of the Prestige. Neither nutrients nor microorganisms meant an improvement with respect to the natural processes. The addition of biodiesel improved the appearance of the treated tiles and apparently accelerated the degradation of the aliphatic and aromatic fractions of the residual fuel oil. Nevertheless, PAHs degradation was similar and very high in all the treatments (80-85% after 60 days). On the other hand, the evolution with time of the amount of vanadium was similar to that of 17α(H),21β(H)-hopane, so it was concluded that vanadium could also be used to estimate the extent of oil degradation in the field. These results also suggested that the residual fuel oil mineralization was very low throughout 1 year in all the treatments. Moreover, the increase of the oxygen content of the residual oil from around 1% till 4-8% indicated that the partial oxidation of hydrocarbons took place, and that the hydrocarbon oxidation products accumulated in the polar fractions. In general, the results pointed out that bioremediation techniques were not suitable for the recovery of shores affected by heavy oil spills

  8. A field demonstration of the efficacy of bioremediation to treat oiled shorelines following the Sea Empress incident

    Bioremediation was investigated as a method of treating a mixture of Forties Crude Oil and Heavy Fuel Oil stranded on Bullwell Bay, Milford Haven, UK after the grounding of the Sea Empress in 1996. A randomised block design in triplicate was used to test the efficacy of two bioremediation treatments: a weekly application of mineral nutrient dissolved in sea water and a single application of a slow-release fertiliser. Each treatment supplied an equivalent amount of nitrogen and phosphorus. Concentrations of residual hydrocarbon normalised to the biomarker 17α(H),21β(H)-hopane showed that after two months the oil was significantly (p<0.001) more biodegraded in the treated plots than in the controls. On average, the oil in the nutrient amended plots was 37% more degraded than that found in the controls. There was no evidence that the bioremediation treatment increased the toxicity of the oiled sediment. The results confirm that bioremediation can be used to treat a mixture of crude and heavy fuel oil on a pebble beach. In particular, the data suggest that the application of a slow-release fertiliser alone may be a cost-effective method of treating low-energy, contaminated shorelines after a spill incident.
