Lizaso, G., Beriain, Ma. J., Horcada, A., Chasco, J. and Purroy, A. 2011. Effect of intended purpose (dairy/beef production) on beef quality. Can. J. Anim. Sci. 91: 97–102. Fifteen Pirenaica (beef) heifers and fifteen Holstein-Friesian (dairy) heifers were compared to consider the effect of intended purpose of the breed on meat quality. Animals were slaughtered at around 12.4 mo of age. Carcass weight was 247.6 kg for Pirenaica and 229.2 kg for Holstein-Friesian heifers. pH24hours, moisture, fat, protein, ash, water holding capacity, CIE L*a*b* and C* and H* values, collagen content, and shear force were determined in longissimus dorsi muscle. Sensory analysis of meat was performed to obtain the texture profile, scored by a trained taste panel. Sensorial differences of meat were mainly in relation to higher fat content observed in Holstein-Friesian (2.87%) vs. Pirenaica breed (1.82%) (P<0.01). Total and soluble collagen contents for the two breeds differed (P<0.01 and P<0.05, respectively) but did not result in different meat tenderness scores by taste panelists. Higher water-holding capacity in meat of Holstein-Friesian was observed (P<0.01). CIE L*a*b*, coordinates C* and H* values were not different between breeds. Sustained juiciness and oiliness were higher in Holstein-Friesian than Pirenaica (P<0.05 and P<0.01, respectively). Results suggest that beef characteristics of young heifers of dairy and beef breeds are similar with the exception of characteristics related to juiciness.

Abstract. During the "African Monsoon Multidisciplinary Analysis" (AMMA) field phase in August 2006, a variety of measurements focusing on deep convection were performed over West Africa. The German research aircraft Falcon based in Ouagadougou (Burkina Faso) investigated the chemical composition in the outflow of large mesoscale convective systems (MCS). Here we analyse two different types of MCS originating north and south of the intertropical convergence zone (ITCZ, ~10° N), respectively. In addition to the airborne trace gas measurements, stroke measurements from the Lightning Location Network (LINET), set up in Northern Benin, are analysed. The main focus of the present study is (1) to analyse the trace gas composition (CO, O3, NO, NOx, NOy, and HCHO) in the convective outflow as a function of distance from the convective core, (2) to investigate how different trace gas compositions in the boundary layer (BL) and ambient air may influence the O3 concentration in the convective outflow, and (3) to estimate the rate of lightning-produced nitrogen oxides per flash in selected thunderstorms and compare it to our previous results for the tropics. The MCS outflow was probed at different altitudes (~10–12 km) and distances from the convective core (<500 km). Trace gas signatures similar to the conditions in the MCS inflow region were observed in the outflow close to the convective core, due to efficient vertical transport. In the fresh MCS outflow, low O3 mixing ratios in the range of 35–40 nmol mol−1 were observed. Further downwind, O3 mixing ratios in the outflow rapidly increased with distance, due to mixing with the ambient O3-rich air. After 2–3 h, O3 mixing ratios in the range of ~65 nmol mol−1 were observed in the aged outflow. Within the fresh MCS outflow, mean NOx (=NO+NO2) mixing ratios were in the range of ~0.3–0.4 nmol mol−1 (peaks ~1 nmol mol−1) and only slightly enhanced compared to the background. Both lightning-produced NOx (LNOx) and NOx transported upward from the BL contributed about equally to this enhancement. On the basis of Falcon measurements, the mass flux of LNOx in the investigated MCS was estimated to be ~100 g(N) s−1. The average stroke rate of the probed thunderstorms was 0.04–0.07 strokes s−1 (here only strokes with peak currents ≥10 kA contributing to LNOx were considered). The LNOx mass flux and the stroke rate were combined to estimate the LNOx production rate. For a better comparison with other published results, LNOx estimates per LINET stroke were scaled to Lightning Imaging Sensor (LIS) flashes. The LNOx production rate per LIS flash was estimated to 1.0 and 2.5 kg(N) for the MCS located south and north of the ITCZ, respectively. If we assume, that these different types of MCS are typical thunderstorms occurring globally (LIS flash rate ~44 s−1), the annual global LNOx production rate was estimated to be ~1.4 and 3.5 Tg(N) a−1.

Published: March 2011

Abstract. In this paper, we describe in situ observations of mid-latitude cirrus cloud band carried out on 16 May 2007 during the CIRCLE-2 experiment. The Polar Nephelometer and the Cloud Particle Imager (CPI) instruments with PMS FSSP-300 and 2D-C probes were used for the description of the optical and microphysical cloud properties. Two selected cloud regions are compared and discussed in detail. Significant differences in optical properties are evidenced in terms of 22° halo occurrences even though prevalent planar-plate ice crystals are observed in both cloud regions. Featureless scattering phase functions are measured in the first cloud region located near the trailing edge of the cirrus-band at about 11 800 m/−57 °C. In contrast, well pronounced 22° halo peaks are observed with predominant similar-shaped ice crystals near the cirrus-band leading edge at 7100 m/−27 °C. CPI ice crystal images with Polar Nephelometer observations are carefully analysed and interpreted from a theoretical light scattering model in order to explain occurrence and non-occurrence of the 22° halo feature. The results highlight that the halo peaks are inherent only in perfect plate ice crystals (or pristine crystals). On the basis of previous datasets in mid-latitude cirrus, it is found that simple pristine crystals are uncommon whereas particles with imperfect or complex shapes are prevalent. As a result, phase functions that are smooth and featureless best represent cirrus scattering properties.

Published: March 2011

Abstract. An FSSP-100 Optical Particle Counter designed to count and size particles in the micron range and a backscattersonde that measures in-situ particle optical properties such as backscatter and depolarization ratio, are part of the payload of the high altitude research aircraft M55 Geophysica. This aircraft was deployed in tropical field campaigns in Bauru, Brasil (TROCCINOX, 2004) Darwin, Australia (SCOUT-Darwin, 2005) and Ouagadougou, Burkina Faso (SCOUT-AMMA, 2006). In those occasions, measurements of particle size distributions and optical properties within cirrus cloud were performed. Scope of the present work is to assess and discuss the consistency between the particle volume backscatter coefficient observed by the backscattersonde and the same parameter retrieved by optical scattering theory applied to particle size distributions as measured by the FSSP-100. In addition, empirical relationships linking the optical properties measured in-situ by the backscattersonde, which generally can be obtained by remote sensing techniques (LIDAR), and microphysical bulk properties like total particle number, surface and volume density will be presented and discussed.
Optical method for measuring bed topography and flow depth in an experimental flume
Authors: Limare A. , Tal M. , Reitz M. D. , Lajeunesse E. , Métivier F.
Published: March 2011

Abstract. We describe an optical method known as moiré for acquiring quasi-simultaneous measurements of bed topography and flow depth in laboratory experiments. The moiré method is based on projecting a fringe pattern (grating) on the bed and analyzing the deformation of the pattern caused by the topography with respect to a reference plane. The height of the object is encoded in the phase of the pattern and can be retrieved either through Fourier transform or phase shifting algorithms. The methodology enables image-based non-contact measurements over a continuous surface at very high spatial and temporal resolutions. We use a commercial software package of a moiré method called Light3D to map bed topography and flow depth in an experimental braided channel and demonstrate how the method can be used to characterize a full range of statistics not previously possible.

Published: March 2011

At the University of Glasgow, Leroy Cronin is leading a group of scientists that are pioneering the engineering of a fundamentally new approach to building materials, which scales up from the nano scale to the micro. Cronin reflects on the possibilities of this new paradigm that gives inorganic cellular materials the potential to be ‘programmed’ to sense environmental changes, generate power, self‐repair, shift properties and even compete with other building materials for resources.

How Protocells Can Make ‘Stuff’ Much More Interesting
Authors: Armstrong Rachel
Published: March 2011

Rachel Armstrong explains why living systems with their own metabolisms provide more exciting and far‐reaching solutions than conventional building materials. She also explicitly explains why the pursuit of protocell technology, which enables us to artificially design living systems, is so much more promising than established methods, such as incorporating high‐maintenance biological features – green walls or roofs – into existing urban context or applying biomimicry to traditional materials.

Published: March 2011

Paul Preissner provides a typological prototype for the protocell, the Protocell Tower. Does it, however, already look familiar? Though a breathtaking chemical innovation, could protocell technology actually be behind the curve of architecture? Could it be that architects have already been playing with the aesthetics of this unrealised matter for the last 15 years? Preissner suggests some urban approaches that might enable us to use protocells to rejuvenate existing architecture. Copyright © 2011 John Wiley & Sons, Ltd.
AVATAR and the Politics of Protocell Architecture
Authors: Clear Nic
Published: March 2011

The Advanced Virtual and Technological Architecture Research Laboratory (AVATAR) was founded in 2004 at the Bartlett School of Architecture, University College London (UCL). The original remit was to provide a forum for staff and their units to exchange and share their explorations into the digital and visceral terrain. With Neil Spiller's appointment in September 2011 as Dean of the School of Architecture and Construction at the University of Greenwich, the centre of research has shifted south to Greenwich. Here, one of the principle proponents of AVATAR, Nic Clear describes why, given the present economic and political situation, Protocell Architecture has provided the group with such a fecund field of research.

ZrCSiC Materials from the Polymer‐Derived Ceramics Route
Authors: Pizon David , Lucas Romain , Foucaud Sylvie , Maître Alexandre
Published: March 2011

A method to manufacture composites ZrCSiCp using a polymer‐derived ceramic route for SiC is reported. The key point of this approach was the use of SiC precursor polymers synthesized from a vinylsilane monomer, to enhance organic–inorganic interactions between ZrC mineral phase and the polymer. The results were compared with a commercial polycarbosilane, the polycarbomethylsilane. After heat treatment until 1400 °C, XRD analysis indicated the formation of a β‐SiC phase in presence of ZrC. SEM observations emphasized the role of the polymer structure on the final microstructure. The mechanisms of thermal and chemical cross‐linking were investigated, as well as the thermal behaviour of polymers.
On the Atomic Anisotropy of Thermal Expansion in Bulk Metallic Glass

Published: March 2011

Glass transition temperature and plastic yield strength are known to be correlated in metallic glasses. We have observed by in situ synchrotron high energy X‐ray diffraction anisotropy of the thermal expansion behavior in the nearest neighbor and second nearest neighbor atomic distances in the building blocks of ZrCuNiAl based bulk metallic glass, leading inevitably to shear. Mechanical yielding of the latter on the atomic scale leads to the glass transition and the increase of the free volume. These experimental results uncover the mechanism, how glass transition and yield strength are linked.
Preceramic Paper Derived Alumina/Zirconia Ceramics
Authors: Gutbrod Björn , Haas Daniel , Travitzky Nahum , Greil Peter
Published: March 2011

Preceramic paper offers a novel approach for manufacturing of lightweight ceramic structures applying versatile paper shaping technologies. Substitution of bioorganic pulp fibers in alumina loaded preceramic paper by inorganic short zirconia fibers was investigated. A retention of more than 90 wt% was achieved by a combination of cationic and anionic retention aids. Powder packing density in the paper sheet decreased with increasing amount of non‐deformable zirconia fibers used to substitute highly deformable pulp fibers. Applying post‐pressing, however, resulted in a pronounced improvement of packing density while retaining excellent flexibility and strength of the preceramic paper preform. Thus, preceramic paper containing a zirconia fiber volume fraction of 19% sintered at 1 600 °C attained a rupture strength measured by ball‐on‐three‐balls loading of 120 ± 17 MPa (porosity 44%) which after pressure consolidation of the paper increased to 180 ± 49 MPa (porosity 28%).
An experimental investigation of nucleate pool boiling in aqueous solutions of a polymer

Published: March 2011

Nucleate boiling characteristics of aqueous solutions of hydroxyl ethyl cellulose (HEC QP‐300; M ∼ 600 kg/mol) in different concentrations (1.0 × 10−9 ≤ C ≤ 4.0 × 10−9 mol/cc) are reported. These are viscous non‐Newtonian, shear‐thinning solutions that also display interfacial tension relaxation, which has both a concentration‐dependent and temporal behavior; surface wetting increases as well, as measured by the reduction of contact angle. The measured pool boiling heat transfer from an electrically heated horizontal cylinder in C = 1.0 × 10−9 mol/cc aqueous solution is found to be enhanced by ∼20% over the entire heat flux range (4.0 < q < 200 kW/m2). In higher concentration solutions, however, heat transfer degrades at low heat fluxes (incipience and partial boiling) with subsequent enhancement (∼45% maximum) at high heat fluxes or in the fully‐developed nucleate boiling regime. This anomalous boiling behavior in the two regimes, characterized by respectively different ebullience signatures, is shown to be scaled with changes in the liquid‐solid interface wetting, vapor‐liquid interfacial tension, and shear‐thinning viscosity of the polymeric solutions. © 2011 American Institute of Chemical Engineers AIChE J, 2012

Objective

To describe the Alzheimer disease (AD)‐like clinical and pathological features, including marked neurofibrillary tangle (NFT) pathology, of a familial prion disease due to a rare nonsense mutation of the prion gene (PRNP).

Methods

Longitudinal clinical assessments were available for the proband and her mother. After death, both underwent neuropathological evaluation. PRNP was sequenced after failure to find immunopositive Aβ deposits in the proband and the documentation of prion protein (PrP) immunopositive pathology.

Results

The proband presented at age 42 years with a 3‐year history of progressive short‐term memory impairment and depression. Neuropsychological testing found impaired memory performance, with relatively preserved attention and construction. She was diagnosed with AD and died at age 47 years. Neuropathologic evaluation revealed extensive limbic and neocortical NFT formation and neuritic plaques consistent with a Braak stage of VI. The NFTs were immunopositive, with multiple tau antibodies, and electron microscopy revealed paired helical filaments. However, the neuritic plaques were immunonegative for Aβ, whereas immunostaining for PrP was positive. The mother of the proband had a similar presentation, including depression, and had been diagnosed clinically and pathologically as AD. Reevaluation of her brain tissue confirmed similar tau and PrP immunostaining findings. Genetic analysis revealed that both the proband and her mother had a rare PRNP mutation (Q160X) that resulted in the production of truncated PrP.

Interpretation

We suggest that PRNP mutations that result in a truncation of PrP lead to a prolonged clinical course consistent with a clinical diagnosis of AD and severe AD‐like NFTs. Ann Neurol 2010;

Published: March 2011

Amyotrophic lateral sclerosis (ALS) is a progressively fatal, incurable, neurodegenerative disorder. In this study, we investigated whether olfactory ensheathing cells (OEC) transplantation could provide protection to motor neurons and enable remyelination in mutant SOD1G93A transgenic rats with ALS. Seventy‐two rats were divided into four groups: SOD1G93A rats (n = 20); medium+SOD1G93A rats (n = 20); OECs+SOD1G93A rats (n = 24); and another eight wild‐type rats were used as controls. About 5 μL (1 × 105) OECs in DF12 medium was injected into the dorsal funiculus of the thoracic spinal cord at a predetermined depth. Survival analysis revealed a significant increase in the survival time in OEC+SOD1G93A rats. Body weight records and inclined board test showed a significant difference between OEC+SOD1G93A and SOD1G93A from the onset at 7 days to 11 days (P < 0.05). Four weeks following transplantation, motor neuron counts in the ventral horn of the spinal cord noted a significant motor neuron loss in SOD1G93A rats when compared with wild‐type rats (P < 0.001), and much less neuronal loss and collapse was noted in OEC+SOD1G93A rats when compared with SOD1G93A rats(P < 0.001); immunohistochemistry and Western blot analysis of choline acetyltransferase supported the motor neuron count. Images of confocal microscope indicated that the transplanted OECs had survived for more than 4 weeks and migrated 4.2 mm through the spinal cord. Evidence of remyelination of transplanted OEC was captured with triple fluorescence labeling of green fluorescent protein, neurofilament, and myelin basic protein and was further confirmed by Western blot analysis of MPB. In conclusion, the transplanted OECs could serve as a source of neuroprotection and remyelination to modify the ALS microenvironment. Anat Rec, 2011. © 2011 Wiley‐Liss, Inc.
Estimation of head tissue‐specific exposure from mobile phones based on measurements in the homogeneous SAM head

Published: March 2011

The maximum spatial peak exposure of each commercial mobile phone determined in compliance with the relevant safety and product standards is publicly available. However, this information is not sufficient for epidemiological studies aiming to correlate the use of mobile phones with specific cancers or to behavioral alterations, as the dominant location of the exposure may be anywhere in the head between the chin to above the ear, depending on the phone design. The objective of this study was to develop a methodology to determine tissue‐specific exposure by expanding the post‐processing of the measured surface or volume scans using standardized compliance testing equipment, that is, specific absorption rate (SAR) scanners. The transformation matrix was developed using the results from generic dipoles to evaluate the relation between the SAR in many brain regions of the Virtual Family anatomical phantoms and in virtual brain regions mapped onto the homogeneous SAM head. A set of transformation factors was derived to correlate the SAR induced in the SAM head to the SAR in the anatomical heads. The evaluation included the uncertainty associated with each factor, arising from the anatomical differences between the phantoms (typically less than 6 dB (4×)). The applicability of these factors was validated by performing simulations of four head models exposed to four realistic mobile phone models. The new methodology enables the reliable determination of the maximum and averaged exposure of specific tissues and functional brain regions to mobile phones when combined with mobile phone power control data, and therefore greatly strengthens epidemiological evaluations and improves information for the consumer.

Plasmid DNA production for pharmaceutical use: Role of specific growth rate and impact on process design
Authors: Bohle K. , Ross A.
Published: March 2011

Application of plasmid DNA as pharmaceutical to be used in gene therapy and vaccination has been investigated intensively in recent years. To be able to provide sufficient material that is in accordance with quality of pharmaceutical grade it is mandatory to gain comprehensive process knowledge which is even requested by regulatory agencies. Regarding plasmid DNA production the specific growth rate has been identified as one of the key parameters. The reduction of specific growth rate results in an increase of plasmid DNA formation. However, quantitative explanations that allow for efficient process development and design are still missing. The presented study proposes a model that clearly demonstrates the relationship between specific growth rate and plasmid formation due to identification of the specific plasmid production rate as relevant key parameter. In addition the model is proved to serve as a useful tool in process development and design. Biotechnol. Bioeng. 2011;108:2099–2106. © 2011 Wiley Periodicals, Inc.

These compounds have been fully characterized by IR and NMR spectroscopy, elemental analysis, differential scanning calorimetry (DSC), density, and impact sensitivity measurements. Compound 2 decomposes at 124.5 °C (DSC) and the salts decompose over the range 138.6–181.6 °C, thus showing higher thermostability. The calculated detonation pressures (P) for these salts range from 27.2 to 37.8 GPa, and detonation velocities (vD) fall between 8424 to 9482 m s−1; these properties make them competitive energetic materials.

New metal‐containing ionic liquids [Cu(CH3CN)n][Tf2N] (n=2, 4; Tf2N=bis(trifluoromethylsulfonyl)‐ amide) have been synthesised and used as a non‐aqueous electrolyte for the electrodeposition of copper at current densities greater than 25 A dm−2. The tetrahedral copper(I)‐containing cation in [Cu(CH3CN)4][Tf2N] is structurally analogous to quaternary ammonium and phosphonium ionic liquids and overcomes problems of metal solubility and mass transport. Two CH3CN ligands are removed at elevated temperatures to give [Cu(CH3CN)2][Tf2N], which can be used as a concentrated non‐aqueous electrolyte. The structural and electrochemical characterisation of these compounds is described herein.
