Authors: KAYAHAN Betül , KAYAHAN Ali , KARACA İsmail
Published: May 2021

In this study, the orientation of two different predator species [(Coccinella septempunctata L., Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae)) to two different aphids [Aphis fabae Scopoli and Acyrthosiphon pisum Harris (Hemiptera: Aphididae)] was investigated. Y-type olfactometer which was made of glass material with one entrance and two exit openings was used in the study. Different applications were applied to the exit ends of the olfactometer and the orientation of the predators dropped from the entrance end was examined. Individuals passing the marked area (10 cm) on the olfactometer were considered to have turned to that plant. All of the trials were conducted separately for each predator and prey with 10 replications. The counts of the insects advancing on the arms of the olfactometer were made 1, 4 and 8 hours after the release. When looking at the data obtained in the first stage of the study, it was determined that the predator insects mostly gravitate towards the leaves infected with aphids; In the second stage, it was observed that C. septempunctata individuals mostly turned towards the side that was contaminated with A. pisum, and H. variegata individuals mostly turned towards the side that was contaminated with A.fabae. When looking at the data obtained from the study, it was determined that the plants damaged by herbivorous insects show an attractive feature for predators. Accordingly, it was concluded that chemicals obtained from broad bean plants damaged by aphids should be analyzed.

Authors: Mamoor Shahan
Published: May 2021

Breast cancer affects women at relatively high frequency (1). We mined published microarray datasets (2, 3) to determine in an unbiased fashion and at the systems level genes most differentially expressed in the primary tumors of patients with breast cancer. We report here significant differential expression of the gene encoding mab-21 like 1, MAB21L1, when comparing primary tumors of the breast to the tissue of origin, the normal breast. MAB21L1 was also differentially expressed in the tumor cells of patients with triple negative breast cancer. MAB21L1 mRNA was present at significantly lower quantities in tumors of the breast as compared to normal breast tissue. Analysis of human survival data revealed that expression of MAB21L1 in primary tumors of the breast was correlated with overall survival in patients with luminal A subtype cancer, demonstrating a relationship between primary tumor expression of a differentially expressed gene and patient survival outcomes influenced by molecular subtype. MAB21L1 may be of relevance to initiation, maintenance or progression of cancers of the female breast.
Prediction of flow effects in quantitative NMR measurements
Authors: Friebel Anne , Specht Thomas , von Harbou Erik , Münnemann Kerstin , Hasse Hans
Published: May 2021

A method for the prediction of the magnetization in flow NMR experiments is presented, which can be applied to mixtures. It enables a quantitative evaluation of NMR spectra of flowing liquid samples even in cases in which the magnetization is limited by the flow. A transport model of the nuclei’s magnetization, which is based on the Bloch-equations, is introduced into a computational fluid dynamics (CFD) code. This code predicts the velocity field and relative magnetization of different nuclei for any chosen flow cell geometry, fluid and flow rate. The prediction of relative magnetization is used to correct the observed reduction of signal intensity caused by incomplete premagnetization in fast flowing liquids. By means of the model, quantitative NMR measurements at high flow rates are possible. The method is predictive and enables calculating correction factors for any flow cell design and operating condition based on simple static time measurements. This makes time-consuming calibration measurements for assessing the influence of flow effects obsolete, which otherwise would have to be carried out for each studied condition. The new method is especially interesting for flow measurements with compact medium field NMR spectrometers, which have small premagnetization volumes. In the present work, experiments with three different flow cells in a medium field NMR spectrometer were carried out. Acetonitrile, water, and mixtures of these components were used as model fluids. The experimental results for the magnetization were compared to the predictions from the CFD model and good agreement was observed.

A molecular dynamics study on cooling rate effect on atomic structure of solidified silver nanoparticles
Authors: Vo Truong Quoc , Kim BoHung
Published: May 2021

The atomic structures and solidification point of silver nanoparticles (SNPs) are studied in aseries of molecular dynamics simulations based on the empirical embedded atom methods (EAM). Thesolidification point is calculated from the extracted potential energy during the cooling process, whereasthe atomic structures are analyzed using the common neighbor (CN) method. The results indicate that thestructures of the solidified SNPs are very sensitive to both the applied cooling rate and the particle size. Wefind the critical cooling rate where a glassy structure is observed. Below the critical rate, polycrystallinenanoparticles are formed, where the percentage of the close-packed structures, i.e., FCC and HCP, decreaseswith increasing cooling rate. Moreover, the proportion of those structures is always larger with a biggerparticle size for an identical applied cooling rate. The findings in this study provide useful information formany practical applications where the nanostructure strongly affects thermal management and operationalefficiency.

Shear-rate dependence of thermodynamic properties of the Lennard-Jones truncated and shifted fluid by molecular dynamics simulations
Authors: Lautenschlaeger Martin P. , Hasse Hans
Published: May 2021

It was shown recently that using the two-gradient method, thermal, caloric, and transport properties of fluids under quasi-equilibrium conditions can be determined simultaneously from nonequilibrium molecular dynamics simulations. It is shown here that the influence of shear stresses on these properties can also be studied using the same method. The studied fluid is described by the Lennard-Jones truncated and shifted potential with the cut-off radius r*c = 2.5σ. For a given temperature T and density ρ, the influence of the shear rate on the following fluid properties is determined: pressure p, internal energy u, enthalpy h, isobaric heat capacity cp, thermal expansion coefficient αp, shear viscosity η, and self-diffusion coefficient D. Data for 27 state points in the range of T ∈ [0.7, 8.0] and ρ ∈ [0.3, 1.0] are reported for five different shear rates (γ ̇ ∈ [0.1,1.0]). Correlations for all properties are provided and compared with literature data. An influence of the shear stress on the fluid properties was found only for states with low temperature and high density. The shear-rate dependence is caused by changes in the local structure of the fluid which were also investigated in the present work. A criterion for identifying the regions in which a given shear stress has an influence on the fluid properties was developed. It is based on information on the local structure of the fluid. For the self-diffusivity, shear-induced anisotropic effects were observed and are discussed.

PFG-NMR and MD Simulation Study of Self-Diffusion Coefficients of Binary and Ternary Mixtures Containing Cyclohexane, Ethanol, Acetone, and Toluene
Authors: Bellaire Daniel , Kiepfer Hendrik , Münnemann Kerstin , Hasse Hans
Published: May 2021

Recently, Guevara-Carrion et al. published a comprehensive molecular dynamics (MD) study on the thermodynamic properties of binary mixtures containing methanol, ethanol, acetone, benzene, cyclohexane, toluene, and carbon tetrachloride which also includes results on self-diffusion coefficients. However, for the mixtures acetone/cyclohexane, acetone/ethanol, acetone/toluene, cyclohexane/ethanol, and toluene/ethanol, no experimental data on self-diffusion coefficients were available for comparison. Therefore, in the present work, self-diffusion coefficients in these mixtures were measured by 1H NMR spectroscopy using pulsed field gradients (PFGs) at 298.15 K and ambient pressure. The experimental data were compared to the simulations of Guevara-Carrion et al. Good agreement was observed for all mixtures that do not contain ethanol, whereas, for ethanol-containing mixtures, the deviations were larger. This finding is attributed to deficiencies of the molecular model in describing the hydrogen-bonding of ethanol. Furthermore, self-diffusion data for the ternary mixture acetone/toluene/cyclohexane were measured and compared to molecular simulation data from the present work. Good agreement was observed.

Published: May 2021

Medium field NMR spectrometers are attractive for online process monitoring. Therefore, in the present work, a single-stage laboratory batch distillation still was coupled online with a medium field NMR spectrometer. This enables quantitative non-invasive measurements without calibration. The technique was used for studying isobaric and isothermal residue curves in two ternary systems: (dimethyl sulfoxide + acetonitrile + ethyl formate) and (ethyl acetate + acetone + diethyl ether) and boiling curves and high-boiling azeotropes in two binary systems: (acetic acid + pyridine) and (methanol + diethylamine). The results of the online NMR spectroscopic analysis were compared to results from offline analysis as well as to results from thermodynamic modeling using NRTL parameters that were parametrized with literature data. The new method for online process monitoring gives reliable results and is well-suited for fast and robust measurements of residue curves.

Published: May 2021

The distribution of ionic species in electrolyte systems is important in many fields of science and engineering, ranging from the study of degradation mechanisms to the design of systems for electrochemical energy storage. Often, other phenomena closely related to ionic speciation, such as ion pairing, clustering and hydrogen bonding, which are difficult to investigate experimentally, are also of interest. Here, we develop an accurate molecular approach, accounting for reactions as well as association and ion pairing, to deliver a predictive framework that helps validate experiment and guides future modelling of speciation phenomena of weak electrolytes. We extend the SAFT-VRE Mie equation of state [D. K. Eriksen et al., Mol. Phys., 2016, 114, 2724–2749] to study aqueous solutions of nitric, sulphuric, and carbonic acids, considering complete and partially dissociated models. In order to incorporate the dissociation equilibria, correlations to experimental data for the relevant thermodynamic equilibrium constants of the dissociation reactions are taken from the literature and are imposed as a boundary condition in the calculations. The models for water, the hydronium ion, and carbon dioxide are treated as transferable and are taken from our previous work. We present new molecular models for nitric acid, and the nitrate, bisulfate, sulfate, and bicarbonate anions. The resulting framework is used to predict a range of phase behaviour and solution properties of the aqueous acids over wide ranges of concentration and temperature, including the degree of dissociation, as well as the activity coefficients of the ionic species, and the activity of water and osmotic coefficient, density, and vapour pressure of the solutions. The SAFT-VRE Mie models obtained in this manner provide a means of elucidating the mechanisms of association and ion pairing in the systems studied, complementing the experimental observations reported in the literature.
Correction to “Contact Angle of Sessile Drops in Lennard-Jones Systems”
Authors: Becker Stefan , Urbassek Herbert M. , Horsch Martin , Hasse Hans
Published: May 2021

Molecular dynamics simulations are used for studying the contact angle of nanoscale sessile drops on a planar solid wall in a system interacting via the truncated and shifted Lennard-Jones potential. The entire range between total wetting and dewetting is investigated by varying the solid–fluid dispersive interaction energy. The temperature is varied between the triple point and the critical temperature. A correlation is obtained for the contact angle in dependence of the temperature and the dispersive interaction energy. Size effects are studied by varying the number of fluid particles at otherwise constant conditions, using up to 150 000 particles. For particle numbers below 10 000, a decrease of the contact angle is found. This is attributed to a dependence of the solid–liquid surface tension on the droplet size. A convergence to a constant contact angle is observed for larger system sizes. The influence of the wall model is studied by varying the density of the wall. The effective solid–fluid dispersive interaction energy at a contact angle of θ = 90° is found to be independent of temperature and to decrease linearly with the solid density. A correlation is developed that describes the contact angle as a function of the dispersive interaction, the temperature, and the solid density. The density profile of the sessile drop and the surrounding vapor phase is described by a correlation combining a sigmoidal function and an oscillation term.

Published: May 2021

A united atom force field for the homologous series of the poly(oxymethylene)dimethyl ethers (OMEn): H3C–O–(CH2O)n–CH3, is presented. OMEn are oxygenatesand promising new synthetic fuels and solvents. The molecular geometry of the OMEn,the internal degrees of freedom and their electrostatic properties were obtained fromquantum mechanical calculations. To model repulsion and dispersion, Lennard-Jonesparameters were fitted to the experimental liquid densities and vapour pressures of pureOMEn (n “ 1 - 4). The critical properties of OMEn (n “ 1 - 4) were determined fromthe simulation data. Additionally, the shear viscosity of pure liquid OMEn is evaluatedand compared with literature data. Finally, the solubility of CO2 in OME2, OME3and OME4 is predicted using a literature model for CO2 and the Lorentz-Berthelotcombining rules. The results agree well with experimental data from the literature.

Application of NEAT for the Simulation of Liquid-liquid Extraction Processes with Poorly Specified Feeds
Authors: Jirasek Fabian , Burger Jakob , Hasse Hans
Published: May 2021

The conceptual design of fluid separation processes is particularly challenging if the considered mixtures are poorly specified, since classical thermodynamic models cannot be applied when the composition is unknown. We have recently developed a method (NEAT) to predict activity coefficients in such mixtures. It combines the thermodynamic group contribution concept with the ability of NMR spectroscopy to quantify chemical groups. In the present work, we describe how NEAT can be applied to equilibrium stage simulations of liquid–liquid extraction processes with poorly specified feeds. Only a single 13C NMR spectrum of the feed is needed for predicting the distribution of a target component for different process parameters, such as temperature or extracting agent. The predictions from several test cases are compared to results that are obtained using the full knowledge on the composition of the feed and surprisingly good agreement is found.

Thermophysical Properties of Mixtures of Titanium(IV) Isopropoxide (TTIP) and p-Xylene
Authors: Keller Alexander , Wlokas Irenäus , Kohns Maximilian , Hasse Hans
Published: May 2021

Titanium(IV) isopropoxide (TTIP) is an important precursor for the production of nanoparticles by spray flame processes. In these processes, the precursor is provided in a solution in a combustible solvent, which is p-xylene here. As no thermophysical data for solutions of TTIP in p-xylene were available in the literature, they were measured in the present work. The vapor–liquid equilibrium was measured at pressures ranging from 20 to 80 kPa. The specific density, viscosity, thermal conductivity, molar isobaric heat capacity, and self-diffusion coefficients were determined experimentally at 101.3 kPa at temperatures between 293.15 and 373.15 K. Sample compositions cover the range from pure TTIP to pure p-xylene. Chemical reactions in the studied system were considered. The experiments were carried out in such a way that they do not compromise the results for the thermophysical properties. The vapor–liquid equilibrium data were correlated using the NRTL model. Empirical correlations were established for the other properties. The results provide a rational basis for spray flame process design.

Viscous heating and temperature profiles of liquid water flows in copper nanochannel
Authors: Van Dinh Quyen , Vo Truong Quoc , Kim BoHung
Published: May 2021

Understanding nanoscale fluidic transport becomes increasingly important due to the rapid development of nanotechnology and nanofabrication. By using molecular dynamics (MD) simulations, we investigated the viscous heating of water flows in copper nanochannels. The two scenarios that were studied are Couette flows and Poiseuille flows. We observed the scale effects on the distribution of fluid density, streaming velocity, fluid viscosity, and temperature across the channel. The results revealed the significant effects of surface forces on causing a large deviation between simulation results and classical hypothesis. We found that the energy equation coupled with the thermal-slip boundary conditions still fails to predict the temperature distributions. Hereby, further scale effects are taken into account, which leads to better predictions. The model that we developed in this study shows the relative deviation to the simulation data within 5 %, which is small compared to the conventional continuum approach (i.e., up to 51 %).

We show that the rationality of the radicalized agent can be characterized as the calibration of specific parameters that determines a specific modality of thought that we capture in an abstract model we call the R.A.S.H. mentality – a model incorporating a particular risk preference and commitment to action which accounts for essential aspects of the radicalized mind. We propose further to reorient the causal arrow that has been privileged in the models of radicalization so far by linking radicalization to the experience of envy, an emotion that motivates individuals to monitor their surroundings, to assess the prosperity of others, and to seek the eradication of the status divergence. We conclude with the process of typification, which consists in widening the reach of concerns by simultaneously eliminating the particulars of the personal situation motivating the radicalized agent and evoking collective circumstance templates belonging to a repertoire of universal social forms.
Association Between Cognitive Decline and Control Beliefs in Midlife and Moderating Effect of Stress Level
Authors: Rahimpour Ali
Published: May 2021

The current study aims to probe the effect of cognitive abilities on the control of beliefs in midlife. Participants in this study (n=112) were interviewed and completed cognitive functioning tests at two-time waves (T1 and T2) with a 10-year time interval. Participants completed self-reported daily stressors for 12 successive weeks in the second-time wave. In this study, we examined if the cognitive decline was linked to general and domain-specific control beliefs. For this purpose, we measure and analyze longitudinal changes in cognitive abilities relates to control beliefs. We predicted that the association between cognitive decline and control belief would be increased by self-reported stress. We also utilized the expectation-maximization method to estimate missing data and applied multilevel modeling (MLM) to analyze statistical effects. Self-reported daily stressors were associated with significantly less control at work, finance, and health, and participants with more significant cognitive decline reported less external control belief. More cognitive decline was associated with a more significant decrease in averaged control belief over ten years when individuals reported more daily stressors. The current findings can inform interventions aimed to identify factors, such as daily stress, that contribute to daily abilities in the context of cognitive decline.

Fatigue may affect the decision to deploy effort (cost) for a given rewarded outcome (benefit). However, it remains unclear whether these fatigue-associated changes can be attributed to simply feeling fatigued. To investigate this question, twenty-two healthy males made a series of choices between two rewarded options: a fixed, no effort option, where no physical effort was required to obtain a set, low reward vs. a variable, effortful option, in which both the physical effort requirements (i.e. different durations of a sustained contraction performed in the lower limbs) and rewards (i.e. greater monetary incentives) was varied. Effort-based choices were made under two conditions: 1) a rested (control) state, (2) a pre-induced state of perceived fatigue, evoked through physical exertion in the upper-limbs, thus controlling for the physical manifestation of fatigue (i.e. decline in muscular force production) on the decision process. Though prior physical exertion increased the perception of fatigue, participants choice behaviour did not significantly differ between control and fatigue conditions. Across both conditions, participants demonstrated an anticipated aversion to effort, with greater effort requirements reducing the decision to engage in actions associated with higher rewards. However, in the fatigue state only, decision time was prolonged and self-reported confidence in individuals’ ability to perform high effort actions was reduced. The findings suggest that a perceived state of fatigue does not necessarily alter cost/benefit comparisons within effort-based decisions, but may introduce greater uncertainty within choice and reduce self-confidence. These findings evidence altered evaluative processes during decision making under conditions of fatigue.
Diferencias entre coeficientes alfa, con muestras y partes pequeñas; adenda

This paper presenting a computer program written in VB 6.0, to calculate the difference between internal consistency coefficients (Cronbach’s alpha) obtained in independent small samples and with instruments have a small number of parts or items. The comparison of reliability coefficients allow to identify possible differences in amount of measurement error in instruments; this methodology use the hypothesis testing approach for test the null hypothesis of equally reliability coefficients. This situation is tending to be common in clinical practice between psychologists or allied career, and even in the construction phases of instruments of measurement, for example in pilot samples. The proposed technique is from the work of Feldt and Kim (2006), and offers a viable and interesting methodological proposal that expands the analysis of the reliability of instruments of psychological and educational measurement.
Mapping students' interest in a new domain: Connecting prior knowledge, interest, and self-efficacy with interesting tasks and a lasting desire to reengage.

How students experience educational environments and the interconnections between their readiness, task experiences and their long-term desire to reengage with course content are critical questions for educators. Research postgraduate students (n=310) at a research- intensive university in Hong Kong, engaging in a 24-hour introductory teaching course, participated in this study. Learner readiness for the course was assessed as prior Domain interest, self-efficacy, and knowledge. Subsequently, students completed four formative assessments, reported their on-task interest in seven strategically chosen tasks and end-of- course Course and Domain interest. Longitudinal-SEM tested interconnections between readiness components, Task, Course and Domain interest. Initial self-efficacy beliefs for teaching predicted early Task interest, while Domain interest was a predictor of Task interest in explicitly practical task experiences. Strong interconnections between Task interest across the study were evident. Individual written and social (discussion) tasks presented strong contributions to future Course/Domain interest. Implications for theory and practice are discussed.
Hashtag Convergence: #GeorgeFloyd and #Covid19
Authors: Davis Jenny L , Love Tony
Published: May 2021

In the late spring of 2020, amid a global pandemic, George Floyd was killed by police in Minneapolis, Minnesota, triggering mass protests under the banner of the Black Lives Matter movement. We take this moment of coinciding crises as our point of analysis observed through the lens of concurrent hashtags on Twitter. Social media content both reflect and construct the social meanings of topics and events. We thus draw from social media to understand how George Floyd and Covid-19 inform and inflect each other, building a dataset from ~20,000 tweets that unite prevalent hashtags associated with each. Analyses reveal a repeating set of symbolic hooks—death, breath, masks, and voice—encompassing dense and competing narratives about justice and injustice, systemic inequality, degrading trust in institutions, and the changing identity of a nation. These narratives are anchored in the events under study and indexed through co-occurring social media registers. In addition to substantive findings, the study introduces and applies hashtag convergence, a novel methodological approach based on user-generated indexical pairings.

The demand for livestock-derived foods has steadily grown over the past decades and rising incomes and human populations are expected to see demand further increase. It is unclear if current livestock feed resources are adequately prepared to meet future demand especially given the looming challenges of climate change. Many feeds such as grasses, crop by-products, and other biomass may not be widely grown commercially or sold in formal markets but are critical sources of livestock feed in many low-resource settings in which ruminant livestock production is important. The availability of these feed types can determine the extent to which the livestock sector can expand to meet growing, and sometimes critical, demand for animal-source foods. In this paper, we compare country-level projections of livestock demand from a global economic model to simulated data on feed biomass production. Our comparisons account separately for beef, lamb, and dairy demand. The data allow us to assess the future sufficiency of key sources of feed biomass, and hence aspects of the expansion capacity of livestock production in selected countries in Southern Africa. Our simulation results project that given the interacting effects of projected climate change and changes in income and population in the region, there will not be enough feed biomass produced domestically to meet growing demand for livestock products. For three types of feed biomass (feed crops including grains, grasses, and crop by-products) for which future livestock feed sufficiency was examined, our results showed feed sufficiency declines for all three feed types in Malawi and Mozambique, for two out of three in South Africa and for one of three in Zambia, under intermediate and extreme scenarios of climate change in 2050. Our results suggest an urgent need to improve feed biomass productivity to support future supply of animal protein in the study countries.
