Darstellung und Eigenschaften von Komplexen des Typs cis‐(RCN)3M(CO)3 (M = Cr, M, W)

Field: Chemistry (Physical Sciences)

Abstract Metal complexes of the type cis ‐(RCN) 3 M(CO) 3 (M = Cr, Mo, W) have been prepared by different methods starting with M(CO) 6 or, more conveniently, with substituted derivatives of the metal hexacarbonyls. Infrared spectroscopic studies indicate that the strength of the nitrile‐to‐metal bond in cis ‐(RCN) 3 M(CO) 3 is only sligthly influenced by the R group. The chromium compounds cis ‐(RCN) 3 Cr(CO) 3 may be used as starting materials for the preparation of hexaalkylborazine‐chromium‐tricarbonyls.
A radiation closure study of Arctic stratus cloud microphysical properties using the collocated satellite-surface data and Fu-Liou radiative transfer model

Field: Earth and Planetary Sciences (Physical Sciences)

Retrievals of cloud microphysical properties based on passive satellite imagery are especially difficult over snow-covered surfaces because of the bright and cold surface. To help quantify their uncertainties, single-layered overcast liquid-phase Arctic stratus cloud microphysical properties retrieved by using the Clouds and the Earth's Radiant Energy System Edition 2 and Edition 4 (CERES Ed2 and Ed4) algorithms are compared with ground-based retrievals at the Atmospheric Radiation Measurement North Slope of Alaska (ARM NSA) site at Barrow, AK, during the period from March 2000 to December 2006. A total of 206 and 140 snow-free cases (Rsfc ≤ 0.3), and 108 and 106 snow cases (R<sub>sfc</sub> > 0.3), respectively, were selected from Terra and Aqua satellite passes over the ARM NSA site. The CERES Ed4 and Ed2 optical depth (τ) and liquid water path (LWP) retrievals from both Terra and Aqua are almost identical and have excellent agreement with ARM retrievals under snow-free and snow conditions. In order to reach a radiation closure study for both the surface and top of atmosphere (TOA) radiation budgets, the ARM precision spectral pyranometer-measured surface albedos were adjusted (63.6% and 80% of the ARM surface albedos for snow-free and snow cases, respectively) to account for the water and land components of the domain of 30 km × 30 km. Most of the radiative transfer model calculated SW↓<sub>sfc</sub> and SW↑<sub>TOA</sub> fluxes by using ARM and CERES cloud retrievals and the domain mean albedos as input agree with the ARM and CERES flux observations within 10 W m<sup>-2</sup> for both snow-free and snow conditions. Sensitivity studies show that the ARM LWP and r<sub>e</sub> retrievals are less dependent on solar zenith angle (SZA), but all retrieved optical depths increase with SZA.

Estimation of experimental conditions to maximize mussels shell capability in trace metals accumulation.

Field: Environmental Science (Physical Sciences)

The evaluation of mussels shell capability of concentrate heavy metals was performed by means of a set of laboratory experiments conducted with mussels collected in unpolluted sites exposed to sub-lethal concentrations of a known toxic metal. Multiple cycles of accumulation and depuration were carried out all along the experimental period; the constant monitoring of experimental conditions and periodical metal determination in shell and tissue samples allowed the individuation of the accumulation and depuration patterns in both Bivalves materials in the selected species. Alternative exposure to contaminated and clean seawater respectively was performed in order to record the different metal concentration trends in shell and soft tissues. In fact it is demonstrated that once the metal is incorporate in the crystalline calcium carbonate lattice, his loss from the shell during mussels lifetime can be considered of no concern; in the other hand it is known that soft tissues are able to release contaminants in response to changed environmental conditions. The aim was to establish a set of experimental conditions able to optimize metal accumulation in mussel hard parts and to calculate the specific MATC (Maximum Acceptable Toxic Concentration) value. So it was possible to settle physical, chemical and physiological parameters in order to maximize the shell metal content and set the basis for implementation of bioinertization strategies exploiting mussels metabolic activity and detoxification mechanisms.
Activation affects access to the platelet receptor for adhesive glycoproteins.

Field: Medicine (Health Sciences)

Blood platelets have a receptor for macromolecular adhesive glycoproteins, located on a heteroduplex membrane glycoprotein complex (GPIIb/IIIa) that only becomes "exposed" when platelets are activated. Binding of the adhesive glycoproteins, in particular fibrinogen, to the receptor is required for platelet aggregation, which in turn is required to arrest bleeding. A murine monoclonal antibody whose rate of binding to the receptor is affected by platelet activation was both cross-linked and fragmented to assess the effects of changes in molecular size on its rate of binding to unactivated and activated platelets. The results indicate that small molecules can bind more rapidly to the receptors on unactivated platelets than can large molecules and that activation involves a conformational and/or microenvironmental change that permits the large molecules to bind more rapidly.
Computational Fluid Dynamics Investigations of Shock Waves in Safety Relief Valves

Field: Engineering (Physical Sciences)

Safety Relief Valves plays an important role in any pressurised system. The proper design of safety relief valves should consider the eective opening and closing characteristics to achieve the desired valve performance. One of the challenges in any valve design is the elimination of Shock waves. Shock waves are characterised by sudden pressure increase and Mach number drop. Detecting shock waves in safety relief valves using computational uid dy- namics could asses valve design to eliminate the shock waves. I t have been proven that the Reynolds Averaged Navier Stocks (RANS) equations with the k- turbulence model could model the internal gas ow in safety relief valves. The RANS and k- turbulence have been solved by a commercial CFD code. In safety valves discharge ow rate and closing and opening behaviours dependon the upstream pressure and certain critical areas. In this study, the eect of the upstream pressure has been discussed. Upstream pressure range was from 7 to 140 bars. The eect of the valve geometry has been discussed as well. Dierent critical outlet areas and divergent angles have been changed to investigate its eect on the shock wave parameters.The upstream pressure eect on shock wave occurrence and intensity have been studied. The results showed that, computational uid dynamics can be used to predict the location of the shock wave. In addition to determining the pressure peak and the Mach number drop and other properties which help eliminating shock wave occurrence in valve design. An ecient design should consider the geometrical and ow parameters that aect the shock wave occurrence and intensity.
Are we ready for beyond-application high-volume data? The Reeds robot perception benchmark dataset

Field: Computer Science (Physical Sciences)

This paper presents a dataset, called Reeds, for research on robot perception algorithms. The dataset aims to provide demanding benchmark opportunities for algorithms, rather than providing an environment for testing application-specific solutions. A boat was selected as a logging platform in order to provide highly dynamic kinematics. The sensor package includes six high-performance vision sensors, two long-range lidars, radar, as well as GNSS and an IMU. The spatiotemporal resolution of sensors were maximized in order to provide large variations and flexibility in the data, offering evaluation at a large number of different resolution presets based on the resolution found in other datasets. Reeds also provides means of a fair and reproducible comparison of algorithms, by running all evaluations on a common server backend. As the dataset contains massive-scale data, the evaluation principle also serves as a way to avoid moving data unnecessarily. It was also found that naive evaluation of algorithms, where each evaluation is computed sequentially, was not practical as the fetch and decode task of each frame would not scale well. Instead, each frame is only decoded once and then fed to all algorithms in parallel, including for GPU-based algorithms.
Property Investment Appraisal

Field: Economics, Econometrics and Finance (Social Sciences)

ABSTRACT This paper considers the application of discounted cash flow (DCF) techniques to the analysis of the property investment market. The traditional method of property valuation is briefly outlined and its shortcomings highlighted. An alternative DCF procedure is derived to calculate the present value of a property investment. This method will be familiar to actuaries, but is not always used in property disciplines. The sensitivities of this formulation to changes in the force of real interest, force of real rental growth and force of inflation are derived. It is suggested how these formulae may be used for property investment appraisal and risk analysis. We conclude that DCF offers a more flexible and accurate means of estimating the value of a property, and that property valuers, financial economists and actuaries should work jointly to develop practical DCF methods. However, so long as traditional methods of valuation prevail, a rational investor must use both methods to identify mispriced property assets. There have been few property contributions to the actuarial literature in the United Kingdom; this paper is intended to build on the few previous papers and suggests directions for future work.
Evaluation of Early-Stage Fatigue Damage in Metal Plates Using Quasi-Static Components of Low-Frequency Lamb Waves

Field: Engineering (Physical Sciences)

Abstract Nonlinear Lamb waves including second harmonic and acoustic-radiation-induced quasi-static components (QSC) have a potential for accurately evaluating early-stage fatigue damage. Most previous studies focus on second-harmonic-based techniques that require phase velocity matching and are hard to isolate interferences from ultrasonic testing systems. The aforementioned requirement and deficiency limit applications of the second-harmonic-based techniques. In this study, a QSC-based technique of low-frequency Lamb waves is proposed for early-stage fatigue damage evaluation of metal plates, which does not need to require phase velocity matching and can remove interferences from ultrasonic testing systems. Both in simulations and in experiments, the primary Lamb wave mode at a low frequency that meets approximate group velocity matching with the generated QSC is selected. In finite element simulations, different levels of material nonlinearities by changing the third-order elastic constants are used to characterize levels of fatigue damage. Numerical results show that the magnitude of the generated QSC pulse increases with the levels of fatigue damage. Early-stage fatigue damage in aluminum plates with different fatigue cycles is further experimentally evaluated. The generated QSC pulse is extracted from received time-domain signals using the phase-inversion technique and low-pass digital filtering processing. The curve of the normalized relative acoustic nonlinearity parameter versus the cyclic loading number is obtained. Numerical simulations and experimental results show that the early-stage fatigue damage in aluminum plates can effectively be evaluated using the QSC generated by low-frequency Lamb waves.
Effect of Amylopectin Content on Mechanical, Barrier and Thermal Properties of Plasticized Starch/Chitosan Films

Field: Materials Science (Physical Sciences)

Mechanical, barrier, and thermal properties of films based on blends of corn starch and chitosan plasticized with ethylene glycol, glycerol, and sorbitol were investigated. Starch amylopectin variation was explored, and contents of 100% and 73% were employed to blend with chitosan and polyols. The findings showed that high amylopectin content has a significant effect (p < 0.05), resulting in films with lower tensile strength (TS) and reduced water vapor permeability (WVP). On the other hand, the incorporation of polyols showed a significantly high (p < 0.05) elongation at break (EB) for films plasticized with glycerol and sorbitol at high amylopectin content. For chitosan/73% amylopectin film, the addition of plasticizers exhibited no significant difference (p < 0.05) among the samples for TS and WVP results. The amylopectin content played no influence in the degradation stability of the films measured by thermogravimetry (TGA). However, amylopectin content influences the endothermic peak temperature observed by differential scanning calorimetry (DSC) analysis. A reduction of about 15 °C was noticed for the film prepared with high amylopectin content, a behavior correlated to its amorphous structure, capable of retaining more water than a crystalline region.
Effects of row spacing and nitrogen topdressing fertilization on the yield of upland rice in a no-tillage system

Field: Agricultural and Biological Sciences (Life Sciences)

ABSTRACT. This study aimed to evaluate the effect of row spacing and nitrogen topdressing fertilization of two materials (genotype 07SEQCL441 CL and cultivar BRS Esmeralda) on the plant height, yield components, grain yield, and quality of an upland rice crop grown in a no-tillage system. Trials were conducted for two growing seasons under field conditions in a 3 x 4 factorial, randomized, complete block design, with four replications. For each material, treatments consisted of the combination of row spacing (0.225, 0.35, and 0.45 m) with nitrogen (N) applied as topdressing (0, 50, 100, and 150 kg ha-1). The lowest row spacing (0.225 m) for genotypes 07SEQCL441 CL and BRS Esmeralda provided a higher number of tillers, number of panicles m-2, and grain yield of rice. Increasing rates of N in the topdressing improved the rice grain yield for both cultivars, but for 07SEQCL441 CL, the grain yield was positively affected only to applications up to 50 kg N ha-1. Row spacing and N rates did not affect the rice grain quality. Therefore, these results indicate that the narrowest row spacing used (0.225 m) with N fertilization as topdressing increased the rice grain yield most in the no-tillage system.
Unscheduled DNA synthesis in cell lysate system reflecting DNA repair in vivo.

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

A cell lysate system by which DNA repair (unscheduled) synthesis induced by DNA damaging agents can be measured at high sensitivity as previously reported (9, 18) was characterized. Time-course experiments in which the in vivo incubation time with hydroxyurea and arabinofuranosyl cytosine after UV irradiation was changed suggested that the number of single strand gaps increased in the presence of these drugs. Alkaline sucrose density gradient analysis of prelabeled DNA revealed that the repair apparatus in the drug-treated cells was not irreversibly impaired. Product DNA in this lysate system was compared with that of an in vitro replication system on alkaline CsC1 equilibrium density gradient, and the results showed that DNA synthesis in the lysate system was "repair-type" synthesis. When the cells were labeled with 5-bromo-2'-deoxyuridine (BrdUrd) in vivo and then labeled with [3H] dTTP in vitro, the photolysis of BrdUrd-labeled DNA decreased the molecular weight, indicating that DNA synthesis in the cell lysate was a continuation of DNA repair in vivo.
Sonographic and Disease Activity Findings Related With Medication Change in JIA

Field: Medicine (Health Sciences)

Background Musculoskeletal ultrasound (MSUS) is increasingly used to evaluate pediatric inflammatory arthritis. This study aimed to explore the relationship between MSUS findings with medication modifications in patients with juvenile idiopathic arthritis (JIA) and clinical disease activity measurements (clinical Juvenile Arthritis Disease Activity Score [cJADAS-10], active joint count [AJC], patient/parent global assessment [PPGA], and physician global assessment [PGA]). Methods Data from patients with JIA who underwent a 12-joint (bilateral second and third metacarpophalangeal, wrist, elbow, knee, and ankle) MSUS examination during a 57-month period were collected. Patients were categorized into 2 groups: a medication change group and a control group (patients without medication change). A pediatric-specific MSUS scoring system was used to assess MSUS findings. The association between clinical and MSUS findings was examined for the study groups. Results A total of 38 patients, 23 in the medication change group and 15 in the control group were included. The medication change group had higher AJC, PGA, and cJADAS-10. These patients also had a statistically significant presence of abnormal knee MSUS findings. For other joints, the frequency of abnormal MSUS findings was slightly higher in patients with a medication change, but the difference was not statistically significant. No strong correlation was observed between MSUS findings and clinical disease activity measurements. Conclusions Abnormal MSUS findings were not observed to be higher in patients with a change in medication except for the involvement of the knee joint. Further longitudinal studies are needed to understand the role of MSUS in the medical decision-making process in JIA.
Legacy contaminants in the eastern Beaufort Sea beluga whales (Delphinapterus leucas): are temporal trends reflecting regulations?

Field: Environmental Science (Physical Sciences)

Once deposited onto Arctic ecosystems, persistent organic pollutants (POPs) biomagnify in foodwebs such that relatively high levels have been detected in predators like beluga whales (Delphinapterus leucas). Our study aimed at assessing temporal trends of legacy POPs in eastern Beaufort Sea beluga blubber collected during traditional harvests in the Mackenzie Estuary area, Northwest Territories. Concentrations of polychlorinated biphenyls (PCBs) and 14 pesticides were quantified in 185 blubber samples collected between 1989 and 2015. The majority of legacy POPs analyzed showed no significant changes during the study period (ΣPCBs, Σchlordanes, Σdichlorodiphenyltrichloroethane, hexachlorobenzene, dieldrin, and mirex) and, therefore, did not reflect regulations put into place over the past decades. Although α- (82.6 ± 12.6 and 15.9 ± 1.9 ng/g in 1989 and 2015, respectively) and γ-hexachlorocyclohexane (γ-HCH) (126.6 ± 23.9 and 13.9 ± 0.9 ng/g, respectively) showed significant decrease between 1989 and 2015, β-HCH showed a more complex trend with concentrations increasing between 1989 (71.2 ± 13.4 ng/g) and 2004 (276.8 ± 13.5 ng/g) before decreasing until 2015 (174.7 ± 8.3 ng/g). Differences in trends likely reflect physico-chemical properties affecting transport to the Arctic. With climate change and melting sea ice potentially affecting the transport and release of legacy POPs, continuous monitoring is necessary.
Protein Stability and Surface Electrostatics:  A Charged Relationship

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Engineering proteins to withstand a broad range of conditions continues to be a coveted objective, holding the potential to advance biomedicine, industry, and our understanding of disease. One way of achieving this goal lies in elucidating the underlying interactions that define protein stability. It has been shown that the hydrophobic effect, hydrogen bonding, and packing interactions between residues in the protein interior are dominant factors that define protein stability. The role of surface residues in protein stability has received much less attention. It has been believed that surface residues are not important for protein stability particularly because their interactions with the solvent should be similar in the native and unfolded states. In the case of surface charged residues, it was sometimes argued that solvent exposure meant that the high dielectric of the solvent will further decrease the strength of the charge-charge interactions. In this paper, we challenge the notion that the surface charged residues are not important for protein stability. We computationally redesigned sequences of five different proteins to optimize the surface charge-charge interactions. All redesigned proteins exhibited a significant increase in stability relative to their parent proteins, as experimentally determined by circular dichroism spectroscopy and differential scanning calorimetry. These results suggest that surface charge-charge interactions are important for protein stability and that rational optimization of charge-charge interactions on the protein surface can be a viable strategy for enhancing protein stability.
