Microphysical controls on the stratocumulus topped boundary-layer structure during VOCALS-REx
Authors: Boutle I. A. , Abel S. J.
Published: January 2012

Abstract. Simulations at a range of resolutions are compared to observations from the South-East Pacific taken during VOCALS-REx. It is found that horizontal resolution makes little difference to the bulk properties of the simulated cloud and drizzle, but the highest resolution simulation is able to realistically represent mesoscale features in the cloud field. We focus on the highest resolution simulation and demonstrate that a poor representation of the cloud microphysics results in excessive drizzle production. This promotes persistent drizzle induced decoupling of the boundary layer, giving a poor representation of the observed diurnal cycle of stratocumulus. Two simple changes to the microphysics scheme are implemented, resulting in a more realistic simulation of boundary-layer diurnal decoupling, and improvements to the cloud liquid water path and surface drizzle rate.

Abstract. It has recently been proposed that ripples inherent to the bow shock during radial interplanetary magnetic field (IMF) may produce local high speed flows in the magnetosheath. These jets can have a dynamic pressure much larger than the dynamic pressure of the solar wind. On 17 March 2007, several jets of this type were observed by the Cluster spacecraft. We study in detail these jets and their effects on the magnetopause, the magnetosphere, and the ionospheric convection. We find that (1) the jets could have a scale size of up to a few RE but less than ~6 RE transverse to the XGSE axis; (2) the jets caused significant local magnetopause perturbations due to their high dynamic pressure; (3) during the period when the jets were observed, irregular pulsations at the geostationary orbit and localised flow enhancements in the ionosphere were detected. We suggest that these inner magnetospheric phenomena were caused by the magnetosheath jets.

Authors: Amezquita-Sanchez J. P. , Osornio-Rios R. A. , Romero-Troncoso R. J. , Dominguez-Gonzalez A.
Published: January 2012

Abstract. The occurrence of recent strong earthquakes, the incessant worldwide movements of tectonic plates and the continuous ambient vibrations caused by traffic and wind have increased the interest of researchers in improving the capacity of energy dissipation to avoid damages to civil structures. Experimental testing of structural systems is essential for the understanding of physical behaviors and the building of appropriate analytic models in order to expose difficulties that may not have been considered in analytical studies. This paper presents a hardware-software system for exciting, monitoring and analyzing simultaneously a structure under earthquake signals and other types of signals in real-time. Effectiveness of the proposed system has been validated by experimental case studies and has been found to be a useful tool in the analysis of earthquake effects on structures.

Atomistic Simulation of the Explosion Welding Process
Authors: Saresoja Ossi , Kuronen Antti , Nordlund Kai
Published: January 2012

We study explosion welding process on the atomic level using molecular dynamics simulations. Our simulations show that jet formation—considered necessary for good bonding—is correlated with the instantaneous melting of the interface region. Moreover, we observe peeling off of material (up to 4 nm) from the bonded surfaces. Finally, the structure of the material immediately after the bonding process is observed to be nanocrystalline with crystal sizes of 10–20 nm.
In situ solvothermal synthesis and characterization of transparent epoxy/TiO2 nanocomposites
Authors: Zhang Haiying , Qi Rongrong , Tong Mingkang , Su Yaozhen , Huang Mark
Published: January 2012

A solvothermal process was developed to in situ prepare epoxy (EP)/TiO2 hybrid precursors. The chemical structure of samples was confirmed by X‐ray and Fourier transformed infrared spectroscopy. Field emission scanning electron microscope micrographs of cured EP/TiO2 hybrid composites showed that well‐dispersed TiO2 nanoparticles were successfully in situ formed in epoxy matrix through the solvothermal process. The thermogravimetic analysis, DSC, and gel content measurements showed that EP/TiO2 hybrid precursors were fully cured with the glass transition temperature decreasing gradually. The effect of TiO2 contents on optical and surface properties was investigated in detail. The results indicated that epoxy/TiO2 nanocomposites exhibited excellent UV shielding effect and high visible light transparency. The contact angle of EP/TiO2 nanocomposites, when the content of silane‐coupling agent (KH560) was 5 g and the content of tetrabutyl titanate (TBT) was 3 g, can reach as high as 101°, which was 36° higher than that of pure EP, representing for the increase of hydrophobicity. © 2012 Wiley Periodicals, Inc.

Bleaching of modal/AN‐g‐casein fiber blend with H2O2/TAED activating system
Authors: Li Qing , Tang Hui , Tang Ren‐Cheng
Published: January 2012

The bleaching of modal/AN‐g‐casein fiber blend using hydrogen peroxide/tetraacetylethylenediamine (H2O2/TAED) activating system was investigated, and the influence of key factors on bleaching was determined. The whiteness index of bleached fabrics was greatly affected by sodium carbonate and H2O2/TAED dosages, and the dyeability of bleached fabrics with acid dyes was greatly dependent on H2O2/TAED dosages and bleaching temperature. Compared with the conventional H2O2 bleach under alkaline conditions, the activated bleach markedly decreased the loss of casein in AN‐g‐casein fiber due to its acidic conditions, and exhibited the advantages of energy saving and high efficiency. However, the fabrics bleached using the activated process had the poor acidic dyeing properties due to the oxidation of amino groups in AN‐g‐casein fiber. © 2012 Wiley Periodicals, Inc.

Gene regulatory networks reused to build novel traits
Authors: Monteiro Antónia
Published: January 2012

Co‐option of the eye developmental gene regulatory network may have led to the appearance of novel functional traits on the wings of flies and butterflies. The first trait is a recently described wing organ in a species of extinct midge resembling the outer layers of the midge's own compound eye. The second trait is red pigment patches on Heliconius butterfly wings connected to the expression of an eye selector gene, optix. These examples, as well as others, are discussed regarding the type of empirical evidence and burden of proof that have been used to infer gene network co‐option underlying the origin of novel traits. A conceptual framework describing increasing confidence in inference of network co‐option is proposed. Novel research directions to facilitate inference of network co‐option are also highlighted, especially in cases where the pre‐existent and novel traits do not resemble each other.

α‐Tocopherol (α‐Toc) is involved in various physiologic processes, which present antioxidant and neuroprotective properties. High‐fat diets have an important role in neurodegenerative diseases and neurological disturbances. This study aimed to investigate the effects of treatment with α‐Toc and the consumption of high‐fat diets on ectonucleotidase activities in synaptosomes of cerebral cortex, hippocampus and striatum of rats. Animals were divided into four different groups, which received standard diet (control), high‐fat saturated diet (HF), α‐Toc and high‐fat saturated diet plus α‐Toc (α‐Toc + HF). High‐fat saturated diet was administered ad libitum and α‐Toc by gavage using a dose of 50 mg·kg–1. After 3 months of treatment, animals were submitted to euthanasia, and cerebral cortex, hippocampus and striatum were collected for biochemical assays. Results showed that adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) hydrolysis in the cerebral cortex, hippocampus and striatum were decreased in HF in comparison to the other groups (P < 0·05). When rats that received HF were treated with α‐Toc, the activity of the ectonucleotidases was similar to the control. ATP, ADP and AMP hydrolysis in the cerebral cortex, hippocampus and striatum were increased in the α‐Toc group when compared with the other groups (P < 0·05). These findings demonstrated that the HF alters the purinergic signaling in the nervous system and that the treatment with α‐Toc was capable of modulating the adenine nucleotide hydrolysis in this experimental condition.

Avoiding the slippery slope: preventing the development of diabetes in women with a history of gestational diabetes
Authors: Feig Denice S.
Published: January 2012

Women with a history of gestational diabetes are at increased risk of developing type 2 diabetes. By identifying this high‐risk group who has not yet developed the disease, we have the opportunity to try to prevent this progression to diabetes. In this article, we review the evidence for different strategies used to prevent the onset of diabetes in women with a history of gestational diabetes. These strategies include lifestyle changes, medications and breastfeeding. Copyright © 2012 John Wiley & Sons, Ltd.
Fast investigations from biological matrices using CE – Test of a blood–brain barrier model
Authors: Kühne Sascha , Untucht Christopher , Steinert Michael , Wätzig Hermann
Published: January 2012

In order to adopt a general workflow for complex biological matrices with respect to a new blood–brain barrier (BBB) model, a micellar electrokinetic chromatography method has been developed. The cells forming the BBB have been cultivated in a special cell growth medium in which six drugs (acetaminophen, caffeine, carbamazepine, cimetidine, indometacin and propranolol) have been dissolved and tested for their penetration properties. The results showed good to very good accordance to the reference values. Samples were directly injected onto the capillary without any pretreatment (fused silica capillary, id: 50 μm, L: 48 cm, l: 40 cm). After method development, separations were carried out using a 60 mM borate buffer containing 200 mM of SDS at 30 kV, leading to an analysis time of less than 10 min. Between two runs the capillary was rinsed with a mixture of equal parts of running buffer and isopropanol (70% v/v), which proved to be very effective to remove matrix compounds. An appropriate choice of the detection wavelength (220 or 254 nm) could avoid major interferences between analytes and matrix. The typical RSD% for migration times was approximately 2%, for peak areas, it ranged from 2 to 6%, which was very well acceptable for the generic method used in this study and the low concentrations investigated. The LODs ranged from 10 to 30 ng/mL.
An insight into the abundant proteome of 46BR.1G1 fibroblasts deficient of DNA ligase I

Published: January 2012

This work presents the proteome profile of cultured human skin fibroblasts established from a patient affected by DNA ligase I (Lig I) deficiency syndrome, a rare disorder characterized by immunodeficiency, growth retardation and sun sensitivity. 2‐DE (in the 3–10 and 4–7 pH ranges) was the separation technique used for the production of maps. MALDI‐TOF/MS and LC‐MS/MS were the mass spectrometry platforms applied for the identification of proteins in gel spots. A total of 154 proteins, including 41 never detected before in skin fibroblasts with this approach, were identified in gel spots analyzed. This newly generated extensive database provides for the first time a global picture of abundant proteins in 46BR.1G1 skin fibroblasts. While being relevant to the particular disorder considered, these results may be regarded as an intriguing starting point on the way to achieve a reference map of the proteins highly expressed in an inherited syndrome with defect in DNA replication and repair pathways.
Evaluation of a new battery of toxicity tests for boreal forest soils: Assessment of the impact of hydrocarbons and salts

Published: January 2012

The ability to assess the toxic potential of soil contamination within boreal regions is currently limited to test species representative of arable lands. This study evaluated the use of six boreal plant species (Pinus banksiana, Picea glauca, Picea mariana, Populus tremuloides, Calamagrostis Canadensis, and Solidago canadensis) and four invertebrate species (Dendrodrilus rubidus, Folsomia nivalis, Proisotoma minuta, and Oppia nitens) and compared their performance to a suite of standard agronomic soil test species using site soils impacted by petroleum hydrocarbon (PHC) and salt contamination. To maintain horizon-specific differences, individual soil horizons were collected from impacted sites and relayered within the test vessels. Use of the boreal species was directly applicable to the assessment of the contaminated forest soils and, in the case of the hydrocarbon-impacted soil, demonstrated greater overall sensitivity (25th percentile of estimated species sensitivity distribution [ESSD25] = 5.6% contamination: 10,600 mg/kg fraction 3 [F3; equivalent hydrocarbon range of >C16 to C34] Of/Oh horizon, and 270 mg/kg F3 Ahg horizon) relative to the standard test species (ESSD25 = 23% contamination: 44,000 mg/kg F3 Of/Oh horizon, and 1,100 mg/kg F3 Ahg horizon). For salinity, there was no difference between boreal and standard species with a combined ESSD25 = 2.3%, equating to 0.24 and 0.25 dS/m for the Ah and Ck horizons. The unequal distribution of soil invertebrates within the layered test vessels can confound test results and the interpretation of the toxic potential of a site. The use of test species relevant to boreal eco-zones strengthens the applicability of the data in support of realistic ecological risk assessments applicable to the boreal regions. Environ. Toxicol.

Interannual variation of evapotranspiration in an eastern Siberian larch forest
Authors: Xue Bao‐Lin , Komatsu Hikaru , Kumagai Tomo'omi , Kotani Ayumi , Otsuki Kyoichi , Ohta Takeshi
Published: January 2012

In a deciduous larch forest in eastern Siberia, the mean and standard deviation of the total evapotranspiration (E) during May to September (day of year (DOY) = 121–274) for 2003–2006 were 181.5 and 26.4 mm, respectively. The interannual variation (IAV) in the total E was caused by the IAV in E for the canopy‐foliated period (DOY = 164–253), not by the IAV in the dates of leaf expansion and leaf fall. For the years with higher total E, E in the canopy‐foliated period was consistently higher, which corresponded to the higher soil water content in these years. Copyright © 2012 John Wiley & Sons, Ltd.
