Synthesizing Nanoparticles Using Reactions Occurring in Aerosol Phases

Our ultimate objective is to form nanoparticles by merging oppositely charged nanodroplets containing different constituents of the nanoparticle and construct a desktop apparatus to do this. These nanodroplets will be in oppositely charged aerosols originating from oppositely charged solutions containing the different component of the nanoparticle. In this paper, as the first stage in establishing the feasibility of this concept, we demonstrate that droplets formed from uncharged solutions will merge and the product of such reactions is the same as when their bulk solutions are mixed. We demonstrate that this is the case for three classes of reactions: the chemiluminescent reaction between Luminol and Potassium Ferricyanide, the pH sensitive fluorescence of Umbelliferone and the precipitation of Silver Chromate by reaction of Silver Nitrate with Potassium Chromate. We present arguments that our future goal using oppositely charged droplets is more efficient synthetically and will produce a narrow distribution of nanoparticle sizes.
Protein interactions near crystallization: a microscopic approach to the Hofmeister series

The salting-out effect of simple electrolytes on lysozyme has been studied by measuring the second virial coefficient B 2 of the osmotic pressure as a function of salt concentration, and for different salts. The aim of this work has been to find a microscopic counterpart of the empirical Hofmeister series for the efficiency of cations and anions in inducing protein crystallization. The experimental results show that, for large enough ionic strengths, B 2 scales linearly with the salt concentration. This trend is common to a number of different monovalent salts, however with efficiency strongly dependent on the specific anion. Conversely, changing the cation does not appreciably affect B 2 . The significance of these findings for the investigation of protein interactions near crystallization is discussed.
Efficacy and application of a novel topical anaesthetic wound formulation for treating cattle with Foot-and-Mouth disease: a field trial in Cameroon

Recently, a wound dressing formulation, (Tri-Solfen®, Medical Ethics Pty Ltd, Australia; TS) registered for use in ruminant husbandry in Australia, was registered for Foot-and-Mouth Disease (FMD) therapy in large ruminants in Laos, following clinical observations of improved welfare and healing following treatment of FMD lesions. In November 2019, an FMD outbreak in Cameroon provided an opportunity for a field trial, comparing clinical responses and recoveries to treatments on a sample of cattle (n = 36) comprising three equal groups of animals (n = 12), comparing responses to three treatments:(i) the application to lesions of TS, (ii) the administration of parenteral oxytetraycline commonly used for FMD in Cameroon; and (iii) an untreated control group (C). Appetite scores, lesion healing scores, and changes in dimensions of lesions, were recorded over a 15-day study period. Cattle treated with TS achieved both superior appetite and lesion healing scores with more rapid reduction in dimensions of lesions than other groups. Farmer observations indicated the TS treatment group had a more rapid return to eating with cessation of excessive salivation, and more rapid return of mobility (walking) with absence of overt lameness. The findings indicate that although mortality is usually low in FMD outbreaks, the disease is a debilitating and painful disorder with negative animal welfare impacts that should be addressed. All farmers expressed their desire that the product be made available for use in their region and modelling indicates that TS therapy imposes no additional financial burden on farmers, with the treatment likely to be provided at a similar or reduced cost to current treatment choices. As use of antibiotics for treatment of a viral disease potentially increases pressures for development of antimicrobial resistance and residues in the food chain, TS as an alternative non-antimicrobial therapy should be promoted for wider use in FMD outbreaks.
Impacts of Climate Change and Human Activities on Streamflow in the upper basin of the Yongding River, North China

Quantitative assessment of the effects of climate change and human activities on runoff is very important for regional sustainable water resources utilization. Determining abrupt changes in runoff could enhance identification of the main driving factors for the sudden changes. In this study, the double mass curves analysis combined with field investigation is used to determine abrupt changes in runoff in two sub-catchments of Upper Yongding River Basin(UYRB), while trend analysis via the traditional Mann–Kendall test for the period 1961–2017 is used to identify the basic trend of precipitation, temperature and potential evapotranspiration(E0). The results suggest an insignificant change in precipitation, a significant increase in temperature and a significant decline in E0 in both sub-catchments. For both of the sub-catchments, abrupt changes in runoff occurred in 1982 and 2003. Both Budyko’s curve and double mass curves are used to evaluate the potential impacts of climate variability and human activities on mean annual streamflow. The results showed that, from the 1960s to the 1980s, runoff declined by 20.01% and 22.28% for Xiangshuibu and Shixiali, respectively; from the 1980s to the 2000s, runoff declined by 68.23% and 67.77% respectively. In the variation stage Ⅰ (1983~2003), human activities contributed 90.6% and 62.7% of the mean annual streamflow change in YRB and SRB, respectively. In the variation stage Ⅱ(2004~2017), human activities contributed 99.5% and 93.5% of the change in YRB and SRB, respectively. It is also noted that the first abrupt decline in runoff was actually at the beginning of China’s land reform, when the land reform motivated farmers to productively manage their reallocated lands, agricultural water consumption therefore increased. The second abrupt change point occurred in 2003, when “Capital water resources planning” implemented including water conservation projects and irrigation district construction. In general, human activities, including soil and water conservation projects and water consumption, are found to be the dominant factors responsible for the significant decline in the annual streamflow in the UYRB over the last six decades.
A Novel System for Grasping and Handling Flat and Deformable Objects

For the automated industry, it is important to develop a new mechatronics system, which is able to grasp and manipulate deformable objects in a reliable way. This paper discusses an idea for developing a concept of gripper exploiting the physical proprieties of the objects to be manipulated such as, for example, fabrics textile, sheets of paper or, in general, Flat and Deformable Objects (FDOs). The idea is to build a gripper prototype, which uses two rotational wheels, microspines placed on the fingertips, in order to buckle and lift up the flat material. The methodology and the type of gripper used will be described in detail. Keywords–Flat and Deformable Objects; Grasping; Robotic Manipulation; Friction; Buckling; Microspines; Rotational Hand.
Composite Cathodes for Proton Conducting Electrolytes

Different composite materials made of mixed protonic/electronic conductors, SrCe0.9Yb0. 1O3–δ (10YbSC) or BaCe0.9Yb0. 1O3–δ (10YbBC), and a mixed oxygen‐ion/electronic conductor, La0.6Sr0. 4Co0.2Fe0. 8O3 (LSCF), were investigated for cathode application in intermediate temperature solid oxide fuel cells (IT‐SOFCs) using a high temperature proton conducting BaCe0.8Y0. 2O3–δ electrolyte. Only the LSCF/10YbBC composite was found to be chemically stable. Area specific resistance (ASR) measurements were performed in wet air for LSCF/10YbBC cathodes, changing the weight ratio between the phases and the sintering procedure. The best performance was obtained for the composite cathode containing 50 wt. ‐% of LSCF and 50 wt. ‐% of 10YbBC, sintered at 1,100 °C. Electrochemical impedance spectroscopy (EIS) measurements of the tested cathodes showed two depressed semicircles in the middle and low frequency range, respectively. Performing ASR measurements at different p O 2 allowed us to attribute the two semicircles to charge transfer and oxygen diffusion processes, respectively. The microstructure of the LSCF/10YbBC(1:1) composite cathode was optimised changing the ratio of the particle sizes between the two phases. The lowest ASR values (0.14 Ω cm2 at 700 °C) were observed for the LSCF/10YbBC(1:1) composite cathode with different particle size (sub‐micrometer particles for LSCF and nanometer particles for 10YbBC). Fuel cell polarisation curves demonstrated superior performance of the LSCF/10YbBC (1:1) cathode with respect to Pt.
Bank stock performance during the COVID-19 crisis: does efficiency explain why Islamic banks fared relatively better?

This paper evaluates the stock performance of Islamic banks relative to their conventional counterparts during the initial phase of the COVID-19 crisis (from December 31, 2019, to March 31, 2020). Using 426 banks from 48 countries, we find that stock returns of Islamic banks were about 10–13% higher than those of conventional banks after controlling for a host of the bank- and country-level variables. This study explains the Islamic banks’ superior crisis stock performance by exploring the potential role of pre-crisis bank efficiency. In a univariate analysis, we document higher non-parametric Data Envelopment Analysis (DEA) efficiency levels for Islamic banks than conventional banks in the year preceding the COVID-19 crisis. Our multivariate regressions show that the risk-adjusted DEA efficiency scores can explain crisis stock returns for Islamic banks but not conventional banks. The evidence is robust to alternative measures of stock returns, efficiency models, and other empirical strategies. Finally, we present insight on the importance of key bank characteristics in determining the stock returns of conventional banks during the crisis period.
Recurrence Rate of Hepatitis C Virus After Achieving a Sustained Virologic Response in Kurdistan Region, Iraq

Background: Hepatitis C virus (HCV) is a public health issue. Successful treatment of HCV infection results in sustained virologic response (SVR) in the majority of subjects. Subsequent recurrence of HCV, either from late relapse or reinfection, may occur. The aim of this study was to assess the recurrence rate of HCV in Iraqi patients. Methods: In this study, 113 patients who completed anti-HCV therapy successfully were recruited. While 23 patients received a classical regimen of peg-interferon plus ribavirin, 90 patients received direct-acting antiviral therapy. Those patients were followed up for three years. HCV recurrence rate was calculated using events/ person years of follow-up (PYFU). Results: Among the recruited patients, HCV RT-PCR was positive in 1 (0.88%) patient giving a recurrence rate of 2.95 per 1000 PYFU. When the data were stratified according to the treatment regimen, the recurrence rate was 14.49 per 1000 PYFU in patients who received the classical regimen of interferon and ribavirin. Conclusions: The overall recurrence rate was low in Iraq. No recurrence was recorded in patients received direct-acting antiviral therapy. Further studies are needed with a larger sample size and longer follow-up to determine the relapse rate in Iraq.
Chemical and bacteriological composition of granular methanogenic sludge

Methanogenic sludge granules grown on waste water from a sugar refinery consisted of several bacterial morphotypes embedded in a matrix of extracellular material. Comparison of critical point drying and freeze-drying methods for preparing samples for scanning electron microscopy to determine the presence of extracellular material indicated that the former method permitted observations of extracellular material and intact cells. The effects of different extraction methods used for isolation of these extracellular polymers was also investigated by scanning electron microscopy. Of the various extraction procedures (EDTA, NaOH, autoclaving, water–phenol), water–phenol left most of the cells intact and was found to be a very efficient method of extraction. Extracellular polymers equivalent to 10–20 mg hexose/g of granules were extracted. The high resistance of the granules against disintegration by various chemical methods suggested that different extracellular polymers and probably different groups of organis.
Enhancement of photovoltaic characteristics using a suitable solvent in hybrid polymer/ multiarmed CdS nanorods solar cells

Multiarmed CdS nanorods have been used as the electron acceptors to fabricate efficient hybrid solar cells. It was demonstrated that when pyridine was used as a solvent for spin coating an active layer consisting of MEH-PPV/CdS blend instead of chlorobenzene, short-circuit current of the device can typically be increased by six times. The FTIR transmission spectrum shows that pyridine replaces the surfactant (HDA) molecules attached to the nanocrystals' surface after posttreatment of CdS nanorods by refluxing in pyridine. Transmission electron microscopy, atomic force microscopy, current−voltage characteristics, photocurrent action spectra measurements, and photoluminescence quenching were used to characterize MEH-PPV/CdS blend spin-coated from pyridine solution. Thermal treatment of the blend films can further enhance the short-circuit current in the device. Best device performance was achieved with a power conversion efficiency of 1.17% under AM1.5 illumination (100 mW cm-2), significantly higher than t.
Living Soft Matter Physics : active protein networks govern cell shape changes

A living cell contains flexible, semi-flexible and stiff filaments, forming the cell skeleton, called the cytoskeleton, the detail of which is described in Timon Idema's article. How does this filamentous network rearrange to drive cell shape changes to achieve cell functions such as division and motility? With the metaphor of a spaghetti bowl, the force you need to apply when tossing with your spoon depends on spaghetti (or filament) density, how much they are cooked (their flexibility), and how they stick together. In particular, cells or cell assemblies are elastic, especially at short time scales: when deformed, they recover their initial shape. Pinch your cheek for a few seconds, it will go back. However, at longer time scales, over minutes, days, years, cells can flow: they are viscous. Look at your elbow skin and compare it with a baby one : it has flown. Unlike macromolecular polymer networks (or a spaghetti bowl), living matter is alive, consumes chemical energy through hydrolysis of adenosine triphosphate. Proteins in the cytoskeletal network assemble, slide, or change conformation, therefore complexifying the simple picture of passive elasticity and viscosity. These cytoskeletal networks are able to actively deform a membrane, and drive cell shape changes. The cell membrane separates the cell content from the outside and has a bending energy that amounts to a few dozen times the thermal energy, it is soft and deformable therefore fluctuate at room (or body) temperature. Underneath the cell membrane lies a network of branched and entangled protein filaments (Blanchoin et al., 2014). Actin filaments have the peculiar property that their growth is activated at the membrane through the formation of new branches in the network. "Simplicity is complexity resolved" is a quote from the famous sculptor Constantin Brancusi. Likewise, physicists try to make things simple, as a cell is a complex system. Strippeddown experimental systems were developed that reconstitute cell functions with purified components. Whereas one single filament would simply push by growing against the membrane, strikingly, the complex growth of a branched network generates both inward and outward membrane deformations, which is an extraordinary property of these networks. This push or pull depend on the detailed organisation of the network, the growth velocity of their filaments, and membrane tension, as supported by models based either on reaction kinetics or cooperative properties of actin networks (Dürre et al., 2018; Simon et al., 2019). Further modeling, inspired by these controlled experiments, will help to decipher how cells control their membrane deformations for various functions, from virus uptake to cell motility which dysfunction leads to various diseases. n
Business-cycle reports and the efficiency of macroeconomic forecasts for Germany

ABSTRACT We study the efficiency of growth and inflation forecasts published by three leading German economic research institutes during a period of time ranging from 1970 to 2017. To this end, we examine whether the information used by the research institutes when they formed their forecasts helps to explain the ex-post realized forecast errors. We identify the information that the research institutes used to set up their quantitative forecasts by applying computational-linguistics techniques to decompose the business-cycle reports published by the research institutes into various topics. Our results show that several topics have predictive value for the forecast errors.
Analysis of the heat of breaking glass ampoules.

The heat of breaking was measured on three series of ampoules, containing N2 at various pressures, N2 at various pressures as well as saturated H2O vapor, or different amounts of liquid H2O as well as the saturated vapor in the unfilled space, respectively. This report gives the method to analyze the heat of breaking of ampoules into three factors: the release of mechanical strain stored in the ampoule under a pressure, heat of evaporation of immersion liquid, and rush-in effect of the liquid.
