AbstractObjectiveTo describe a series of ex‐preterm infants admitted to pediatric intensive care unit due to impending hypoxaemic respiratory failure complicated by pulmonary hypertension (PH) who were treated electively combining noninvasive ventilation (NIV) and nebulized iloprost (nebILO).DesignOpen uncontrolled observational study.SettingPediatric Intensive Care Unit, University Hospital.PatientsTen formerly preterm infants with impending hypoxaemic respiratory failure and PH, of whom eight had moderate to severe bronchopulmonary dysplasia.Measurements and Main ResultsMedian age and body weight were 6.0 (2.75–9.50) months and 4.85 (3.32–7.07) kg, respectively. We observed a significant early oxygenation improvement in terms of PaO2/FiO2 increase (P = 0.001) and respiratory rate reduction (P = 0.01). Hemodynamic also improved, as shown by heart rate (P = 0.002) and pulmonary arterial pressure systolic/systolic systemic pressure (PAPs/SSP) ratio reduction (P = 0.0137). NebILO was successfully weaned in positive response cases: 4 infants were discharged on oral sildenafil. Three patients failed noninvasive modality and needed invasive mechanical ventilation; hypoxic–hypercarbic patients were most likely to fail noninvasive approach. Only one patient requiring invasive ventilation died and surviving babies had a satisfactory 1‐month post‐discharge follow‐up.Conclusions.The noninvasive approach combining NIV and nebILO for ex‐preterm babies with impending respiratory failure and PH resulted to be feasible and quickly achieved significant oxygenation and hemodynamic improvements.

Kähler metrics and gauge kinetic functions for intersecting D6‐branes on toroidal orbifolds – The complete perturbative story
Authors: Honecker G. 
Published: December 2011

AbstractWe systematically derive the perturbatively exact holomorphic gauge kinetic function, the open string Kähler metrics and closed string Kähler potential on intersecting D6‐branes by matching open string one‐loop computations of gauge thresholds with field theoretical gauge couplings in 𝒩 = 1 supergravity. We consider all cases of bulk, fractional and rigid D6‐branes on T6/Ω ℛ and the orbifolds T6/(ℤN × Ω ℛ) and T6/(ℤ2 × ℤ2M × Ω ℛ) without and with discrete torsion, which differ in the number of bulk complex structures and in the bulk Kähler potential. Our analysis includes all supersymmetric configurations of vanishing and non‐vanishing angles among D6‐branes and O6‐planes, and all possible Wilson line and displacement moduli are taken into account. The shape of the Kähler moduli turns out to be orbifold independent but angle dependent, whereas the holomorphic gauge kinetic functions obtain three different kinds of one‐loop corrections: a Kähler moduli dependent one for some vanishing angle independently of the orbifold background, another one depending on complex structure moduli only for fractional and rigid D6‐branes, and finally a constant term from intersections with O6‐planes. These results are of essential importance for the construction of the related effective field theory of phenomenologically appealing D‐brane models. As first examples, we compute the complete perturbative gauge kinetic functions and Kähler metrics for some T6/ℤ2 × ℤ2 examples with rigid D‐branes of [1]. As a second class of examples, the Kähler metrics and gauge kinetic functions for the fractional QCD and leptonic D6‐brane stacks of the Standard Model on T6/ℤ6′T6/ℤ6′ from [2] are given.
Miniature‐dispenser‐based bioassay to evaluate the compatibility of powder formulations used in an entomovectoring approach

Published: December 2011

AbstractBACKGROUND: Entomovectoring as a plant protection strategy demands the design of an appropriate bioassay to assess the risks of potential side effects of the powder formulations in the dispenser towards the vectoring insect. This study reports on the development of a laboratory miniature‐dispenser‐based bioassay. This bioassay system was used to investigate the compatibility of five model products, Prestop‐Mix, Signum, kaolin, wheat flour and cellulose, with the bumblebee, Bombus terrestris L.RESULTS: The laboratory one‐way miniature‐dispenser bioassay showed that the fungicides and the carrier/diluent kaolin caused a worker mortality of > 70% after 5 weeks of exposure, while worker loss with wheat flour and cellulose was no higher than in the blank control (i.e. empty miniature dispenser) (<25%). The laboratory two‐way miniature‐dispenser bioassay comprised separated passageways and demonstrated that only kaolin was toxic (89 ± 11%). These results were also confirmed in a flight‐cage experiment. In addition, a negative effect was observed against reproduction/colony development when nests were exposed to kaolin (P < 0.05) in the two‐way miniature‐dispenser and flight‐cage bioassays.CONCLUSIONS: In the context of entomovectoring technology, the developed laboratory two‐way miniature‐dispenser bioassay gives a reliable prediction of the hazards associated with powder products. Additionally, the present data indicate the possibility of using cellulose and kaolin as respective negative and positive control carriers/diluents in future risk assessment experiments. Overall, the results show that, apart from kaolin, the tested fungicides and carriers/diluents are safe to be used with B. terrestris. Copyright © 2011 Society of Chemical Industry

AbstractBACKGROUND: Pheromones of two native leafrollers of economic importance to the New Zealand horticulture industry, Planotortrix octo [(Z)‐8‐tetradecenyl acetate and tetradecyl acetate] and Ctenopseustis obliquana [(Z)‐5‐tetradecenyl acetate and (Z)‐8‐tetradecenyl acetate], were reinvestigated and combined with pheromone of Epiphyas postvittana [light‐brown apple moth, (E)‐11‐tetradecenyl actetate and (E, E)‐9,11‐tetradecen‐1‐yl acetate] to develop a single dispenser for mating disruption of three pest species for integrated pest management.RESULTS: Additional compounds identified from pheromone gland extracts were characterised as repellents for P. octo. However, for C. obliquana from Central Otago, a change in ratio of (Z)‐5‐tetradecenyl acetate and (Z)‐8‐tetradecenyl acetate and the addition of three compounds found in the gland (dodecyl acetate, tetradecyl acetate and hexadecanal) led to a significant improvement in catch over previous lures. Males from Central Otago showed antennal electrophysiological responses to hexadecanal, unlike C. obliquana from Auckland, which did not. Three multiple‐species disruption blends were devised in a single dispenser to target E. postvittana, P. octo and C. obliquana. Disruption of traps was recorded in single‐tree replicates with all three blends, but the five‐component blend was overall most effective at disruption and was deployed area wide in commercial orchard plots.CONCLUSIONS: Deployment of single dispensers into commercial stone fruit orchards led to disruption of trapping for the three species and measurable reductions in insecticide use in cherries, peaches and nectarines without increased fruit damage (assessed in apricots).

Bonding of low temperature co‐fired ceramics to copper and to ceramic blocks by reactive aluminum/nickel multilayers
Authors: Grieseler Rolf , Welker Tilo , Müller Jens , Schaaf Peter 
Published: December 2011

AbstractReactive multilayers of nickel and aluminum were deposited by magnetron sputtering directly onto low temperature co‐fired ceramics (LTCCs) and copper plate for an easy bonding process. The morphology, interface structure, and exact composition of the nanolaminate films were investigated before and after reaction. It was possible to ignite the reaction for all deposited films by electrical spark discharge or by a laser pulse. It was found that the high roughness of the LTCCs enhances the adhesive force of the multilayers to the ceramic. Apart from the directly deposited multilayers, commercially available Nanofoils® covered with 5 µm tin on each side were used for comparison to join two ceramic carriers and also to join LTCCs to copper. In some cases, acceptable resulting bond strengths of the joint were found, a problem being the still poor reproducibility. The tests with the commercial Nanofoils® also showed a mixing of the tin coatings with the used silver based thick film metallization. The latter was printed on the LTCCs. Thus, the experiments confirm that directly deposited reactive multilayers are a promising possibility for joining ceramic devices, either to other ceramics or also to thermally mismatched metallic devices. A careful preparation of the multilayers in composition and total thickness is necessary to adjust the maximal temperature and the heat load to the bonding task in order to achieve best results.
Half metallicity through wide range of lattice constants in Heusler alloys Co2MnGa1−xGex: First‐principles calculations

Published: December 2011

AbstractThe electronic and magnetic properties of Heusler alloys Co2MnGa1−xGex (x = 0.00, 0.25, 0.50, 0.75, and 1.00) have been investigated using first‐principles density functional theory within the generalized gradient approximation (GGA) scheme. The calculations reveal that with increasing x the lattice constants slightly decrease. When x ≥ 0.5, alloys are half‐metallic (HM) ferromagnets and the total magnetic moments obey Slater‐Pauling rule quite well. Mn atoms show high spin states due to the special sites in compounds. The ferromagnetic couplings are observed in Co2MnGa1−xGex alloys. The sensitivity of half‐metallicity and the change of HM gap for specific lattice constants are also discussed in detail. Calculated results show the half‐metallicity of Co2MnGa0.25Ge0.75 can be maintained in a wider lattice constant range.

ABSTRACTThis study monitored stream temperatures over two hydrological years at various nested scales within the large, unregulated river Dee catchment (North East Scotland). These scales were (i) the whole catchment (11 sites along main stem Dee); (ii) the tributary (single sites in main tributaries); (iii) the Girnock (five sites in one subcatchment); and (iv) the reach (26 points across single reach). The aim was to characterize the thermal regime of all locations and compare the magnitude of variation between each scale. The controls on this variation were assessed via a multiple linear regression model using Geographic Information System‐derived catchment data. Temperatures were collected at 15‐min resolution and for further analysis and discussion combined to daily means. At the catchment and subcatchment scales, a west to east gradient in mean and minimum temperatures was observed, largely paralleling changes in altitude. Temperature differences between subcatchments were generally greater than between the sites along the main stem of the Dee. Differences between tributaries reflected differences in their morphology and land use. However, some tributaries had similar thermal regimes, despite different catchment and riparian characteristics. Subcatchment differences in thermal regimes of one of the tributaries corresponded to riparian vegetation reduced diurnal variability in sections dominated by broadleaf woodland. Compared with the larger scales, reach differences in thermal regime were small (e.g. mean temperatures of riffle, pool and margin habitats were within 0.3°C). The most noticeable difference was in relation to the point samples within the backwater area, which has a more constant thermal regime, most probably reflecting its groundwater source. The regression analysis indicated that monthly mean temperatures can be predicted well using elevation and catchment area. Forest cover was a significant explanatory variable during the summer months. However, some of the empirical temperature data from the Dee indicate that similar thermal regimes can result from different physical controls and processes that have important implications for the extrapolation of such predictive models.

AbstractBackgroundResection of hepatic metastases is indicated in selected stage IV colorectal cancer (CRC) patients. A minority will eventually develop pulmonary metastases and may undergo lung surgery with curative intent. The aims of the present study were to assess clinical outcome and identify parameters predicting survival after pulmonary metastasectomy in patients who underwent prior resection of hepatic CRC metastases.MethodsWe performed a retrospective analysis of 27 consecutive patients (median age 62 years; range: 33–75 years) who underwent resection of pulmonary metastases after previous hepatic metastasectomy from CRC in two institutions from 1996 to 2009. All patients underwent complete resection (R0) for both colorectal and hepatic metastases.ResultsMedian follow‐up was 32 months (range: 3–69 months) after resection of lung metastases and 65 months (range: 19–146 months) after resection of primary CRC. Three‐ and 5‐year overall survival rates after lung surgery were 56 and 39%, respectively, and median survival was 46 months (95% CI 35–57). Median disease‐free survival after pulmonary metastasectomy was 13 months (95% CI 5–21). At the time of last follow‐up, seven patients (26%) had no evidence of recurrent disease and 6 of these 7 patients presented initially with a single lung metastasis.ConclusionsResection of lung metastases from CRC patients may result in prolonged survival, even after previous hepatic metastasectomy. Yet, prolonged disease‐free survival remains the exception, and seems to occur only in patients with a single lung lesion.
Prior reproduction and weather affect berry crops in central Ontario, Canada
Authors: Howe Eric J. , Obbard Martyn E. , Bowman Jeff 
Published: December 2011

AbstractPopulations of many perennial plants intermittently produce large seed crops—a phenomenon referred to as mast seeding or masting. Masting may be a response to spatially correlated environmental conditions (the Moran effect), an adaptive reproductive strategy reflecting economies of scale, or a consequence of the internal resource budgets of individual plants. Fruit production by endozoochorous plants representing eight genera varied synchronously over much of central Ontario, Canada, 1998–2009. We tested for effects of weather and prior reproduction on fruit production by comparing AICc values among regression models fit to time series of fruit production scores and partitioning contributions by different predictors to multiple R2 into independent and joint contributions. Fruit production by mountain ash (Sorbus spp.), juneberry (Amelanchier spp.), dogwoods (Cornus spp.), nannyberry (Viburnum lentago), and possibly cherries (Prunus spp.) was inversely related to production in the previous year. These effects were independent of weather conditions, suggesting that intrinsic factors such as internal resource budgets or an adaptive strategy of variable reproductive output influenced fruit production. To our knowledge, this is the first evidence of masting in members of the genera Cornus, Viburnum, and Amelanchier, and in members of Prunus and Sorbus in North America. All species produced fewer fruits when weather conditions were dry, so the Moran effect could have synchronized fruit production both within and among species. Patterns and causes of variation in berry crops have implications for ecosystem dynamics, particularly in boreal and subArctic environments where berry crops are important wildlife foods.
Increased arterial stiffness is associated with high cardiovascular mortality in male Fabry patients
Authors: Nicholls Kathleen 
Published: December 2011

AbstractCardiovascular survival in a cohort of 33 male Fabry patients followed for a median of 7.3 years at a single centre was most strongly associated in a Cox proportional hazard regression model with age and elevated arterial stiffness at baseline. Seven patients died of cardiovascular causes. The presence of cardiomyopathy and renal involvement (either clinical nephropathy or CKD stage >1) were also negatively associated with survival when analysed as single factors. In this small study, presence of hypertension and hypercholesterolemia at baseline did not significantly predict cardiovascular death. The significant effect of elevated arterial stiffness, especially in a small cohort, argues for its clinical utility in individual patient risk assessment and for further intervention studies focusing on therapeutic reduction.

Published: December 2011

Abstract
Groundwater utilization in Nadia district, West Bengal has been subjected to rapid exploitation in the wake of increasing urbanization and production of agricultural commodities. It is, therefore, necessary to evaluate the existing trend and availability of groundwater in time and space and its movement for proper planning in future. In the present study, an attempt has been made develop a groundwater management model using Visual MODFLOW software. The groundwater flow model for the study area was formulated by using input hydrogeological data and appropriate boundary conditions. The groundwater flow pattern of the study area indicates the occurrence of base flow which feed both the Rivers Bhagirathi and Jalangi throughout the year. The computed hydraulic heads were calibrated by comparing with observed groundwater level data for years 2004 to 2006 and were verified with the data of 2007. The outcome of modeling shows that this model can be used for prediction purpose in the future by updating input boundary conditions and hydrologic stresses during the preceding year. The model optimized unit draft for deep tube well as 556.5 m3/day and the same for shallow tube well as 41 m3/day keeping the existing tube well structures in running condition and maintaining the present and recent past trends of groundwater level. The model can be further improved if more spatial and temporal input parameters are available and can be incorporated into the model for more realistic characterization of groundwater flow.

Published: December 2011

Abstract
National Highway-39 is the only lifeline of the state of Manipur. The sector between Karong and Mao is highly landslide prone and frequently blocked the NH-39. The area is represented by Disang and Barail Groups of rock. Considering the importance of NH-39, landslide susceptibility zonation studies along NH-39 between Karong and Mao were carried out following GSI guideline, a modified form of BIS (1998).
Landslide susceptibility zonation map reveals that 57% of the facets belong to low susceptible zone. It is followed by moderate susceptible zone (33%), high susceptible zone (9%) and very low susceptible zone (1%). All the facets of high susceptible zone are concentrated along the road section of NH-39, especially Maram-Mao sector. The landslide susceptibility zonation map gives an overall picture of the stability condition of the hill slopes so it can be used as a base map for planning any developmental scheme or maintenance of the existing one.
Application of Multivariate Statistical Techniques in the Assessment of Water Quality in Sakarya River, Turkey
Authors: Yerel Suheyla , Ankara Huseyin 
Published: December 2011

Abstract
In this paper, the surface water quality of the Sakarya River in Turkey is assessed by using multivariate statistical techniques. These techniques were applied to the chemical parameters obtained from the five different surface water quality observation stations. Factor and principal component analysis results reveal that the agricultural, anthropogenic and domestic pollution caused differences in terms of water quality. Cluster analysis revealed two different clusters of similarities between the stations, reflecting different chemical properties and pollution levels in the studied river. Surface water quality downstream of the river was different from the water quality upstream. Thus, this study shows the usefulness of multivariate statistical techniques for analysis and interpretation in the surface water quality problem.

Published: December 2011

Abstract
The groundwater quality detoriation due to various geochemical processes like saline water intrusion, evaporation and interaction of groundwater with brines is a serious problem in coastal environments. Understanding the geochemical evolution is important for sustainable development of water resources. A detailed investigation was carried out to evaluate the geochemical processes regulating groundwater quality in Cuddalore district of Tamilnadu, India. The area is entirely underlined by sedimentary formations, which include sandstone, clay, alluvium, and small patches of laterite soils of tertiary and quaternary age. Groundwater samples were collected from the study area and analyzed for major ions. The electrical conductivity (EC) value ranged from 962 to 11,824 µS/cm, with a mean of 2802 µS/cm. The hydrogeochemical evolution of groundwater in the study area starts from Mg–HCO3 type to Na–Cl type indicating the cation exchange reaction along with seawater intrusion. The Br/Cl ratio indicates the evaporation source for the ion. The Na/Cl ratios indicate groundwater is probably controlled by water-rock interaction, most likely by derived from the weathering of calcium–magnesium silicates. The plot of (Ca+Mg) versus HCO3 suggests ions derived from sediment weathering. The plot of Na+K over Cl reflects silicate weathering along with precipitation. Gibbs plot indicates the dominant control of rock weathering. Factor analysis indicates dominance of salt water intrusion, cation-exchange and anthropogenic phenomenon in the study.
