Influences on Structure Formation in Surface-Supported Organic Nanostructures

The influence of experimental parameters on structure formation in surface-supported nanostructures is studied by scanning tunneling microscopy and low energy electron diffraction. Hereto, functionalized organic molecules are deposited onto metals or graphite under ultrahigh vacuum or ambient conditions to form networks with varying strength of intermolecular interaction. Studied influencing variables comprise monomer coverage on the surface, lattice and material of a substrate, coadsorption of solvent molecules, deposition rate of monomers, and substrate temperature.
Hindus Us, Muslims, and the Rest Others in Roy's the Ministry of Utmost Happiness

This study explores self and othering in Roy's novel The Ministry of Utmost Happiness. Roy took twenty years to complete this political romance. The narrator of this political romance talks about the others of Indian society, i.e., religious minorities, political traitors, and low caste groups. These others are always striving to secure a place in a biased Indian society. Their quest for identity has often led them to a blind alley where they have found themselves helpless and oppressed evermore. The situation has become worse under the government of the right-wing Hindu party BJP. This study is an attempt to explore the ways how the weaker part of the society is treated as another and outcast in a so-called secular state. Roy has presented the true face of India. This research tries to comprehend her mind and investigates The Ministry of Utmost Happiness multidimensional and multi-layered tale.
Comparison of Online and Offline Methods for Measuring Fine Secondary Inorganic Ions and Carbonaceous Aerosols in the Central Mediterranean Area

Online hourly concentrations of nitrate (NO_3 ^-), sulphate (SO_4 ^(2-)) and ammonium (NH_4^+), and two hourly concentrations of organic carbon (OC) and elemental carbon (EC) were compared with the daily concentrations determined offline from filter samples. The comparison was performed over two months (May and June 2010) at a coastal site characterized by low local pollution, located in the Southern Italy (Central Mediterranean basin). The online measurements of the above inorganic ions and carbonaceous components of the aerosols were carried out using an Ambient Ion Monitor-Ion Chromatograph (AIM IC URG 9000-D) and a Sunset Laboratory Model-4 Semi-Continuous OCEC Field Analyzer, respectively, while the offline analyses were performed with two ion chromatographs instruments (Dionex DX-120 and Dionex 500) and a Sunset Laboratory Dual-Optical Carbonaceous Analyzer (Sunset Laboratory). The collocation of instruments allowed to evaluate the differences between online and offline daily concentrations and to interpret the origin of positive and negative sampling artefacts. As an example, the offline OC concentrations are constantly higher than online concentrations and this is explained by positive artefacts of offline measurements. The analysis was performed separately for days with and without transport of Saharan dust and revealed significant enhancement of concentrations for both inorganic ions and carbonaceous aerosols in the presence of dust. The increase of EC concentrations during dust events may be explained by an increase of emissions transport from sea traffic to the site. Moreover, the results showed that the online instruments may be used at a low polluted site for the acquisition of high temporal resolution data.
Marian Smoluchowski (On the tenth anniversary of his death)

[144] September of the current year (1927) marked tenth anniversary of the death of Marian Smoluchowski.3 Smoluchowski’s works are of outstanding importance not only for the physicist. They are also of extremely high methodological value. Atomism, which thanks to the work of Clausius, Maxwell and Boltzmann, flourished in the second half of the nineteenth century, by the end of the nineteenth century began to fall into disfavor among physicists. The reality of atoms began to be questioned, accompanied by a strengthened impulse to “overcome natural scientific materialism. ”4 In 1898, in the preface to his classic work on the kinetic theory of gases, Boltzmann wrote regretfully that “it would be a great tragedy for science if the theory of gases were temporarily thrown into oblivion because of a momentary hostile attitude toward it, as it happened for example to the wave theory because of Newton’s authority” (Boltzmann 1898, v–vi; Boltzmann 1995, 192 [TN]). Smoluchowski’s works on the theory of Brownian motion5 provided a brilliant new proof of the reality of atoms. Since that time, as Einstein remarks, due in large part to Smoluchowski’s work, universal recognition of the kinetic theory has been established and confidence in the reality of atoms has begun to spread among physicists. This, however, by no means exhausts the significance of Smoluchowski’s works. Boltzmann, with his own work, eliminated the metaphysical gap between reversible and irreversible processes. He showed that “the world clock does not need to be wound up. ”
Functional and Film-forming Properties of Mechanically Deboned Chicken Meat Proteins

Abstract In the present study, the functional properties of mechanically deboned chicken meat proteins (MDCM-Ps) were determined at different pH (2, 4, 6, 8 and 12), and film-forming properties were evaluated depending on MDCM-P (2, 3 and 4 %) and glycerol (30, 40 and 50 %) concentrations. The highest solubility, emulsifying and foaming properties were determined at pH 12. MDCM-P solutions showed non-polyelectrolyte behavior and gelation onset temperature was determined at 36 °C. Film-forming properties of MDCM-P showed that the tensile strength decreased, and elongation at break increased as glycerol concentration increased. Films became more transparent with increasing glycerol and decreasing protein concentration, while water vapor permeability increased with increasing glycerol and protein concentration. Water sorption data of films were fitted to the Guggenheim, Anderson, and De Boer model. In general, equilibrium moisture content of films increased as glycerol level increased. Overall, the results showed that MDCM-P could be useful as a new protein source for both food and packaging industries.
Engineering Disulphide-Free Autonomous Antibody VH Domains to modulate intracellular pathways

An attractive approach to target intracellular macromolecular interfaces is to design small high affinity proteins. In this manuscript a stable, autonomous, human derived non-immunogenic, disulphide-free VH domain, has been engineered for intracellular expression studies. VH domains can be designed to possess a large dynamic repertoire of binders, as opposed to other scaffolds types that are highly rigid and possess fewer sites of random variation. Picomolar inhibitors were identified using phage display against the eIF4F complex, which is commonly hyper-activated in many cancers. These molecules were also shown to impair cellular proliferation and to reduce the expression of malignancy related proteins. Structural characterization elucidated that these VH domains bound eIF4E at the eIF4G interaction interface via a novel binding pose. Molecules able to mimic this pose and interfere with the eIF4F complex are potentially important for wide-ranging tumour therapy applications.

Morphological variations, length-weight relationships and condition factors of Hemichromis camerounensis (Cichliformes, Cichlidae) in three lakes in northern Cameroon

The presence of numerous crater lakes in the Cameroon Volcanic Line offers an exceptional opportunity to study the influence of habitat on the evolution of cichlids. We examined the characteristics of three lake populations of Hemichromis camerounensis, all located on the Adamawa plateau in northern Cameroon. In total, 31 morphometric characters were examined of 277 fish specimens caught in two lakes with an outlet (Dang and Bini) and in a lake without an outlet (Tizong). Length-weight relationships and condition factors were estimated for each population. The physico-chemical parameters of the water were measured. Lake Tizong differed significantly from the other two lakes by its higher values of pH, ​​conductivity and TDS. The length/depth and height/width ratios of different parts of the body and the total number of gill rakers on the first gill arch were significantly reduced in the population of Tizong, which was also characterized by small size individuals. The length-weight relationship was positively allometric for the populations of Bini and Dang but negatively allometric for the population of Lake Tizong. The condition factor of the fish was very low in Tizong. The morphological differences observed between the three populations should be taken into account in any systematic study that includes H. camerounensis populations from the studied zone.
Applications of Parametric and Nonparametric Tests for Event Studies on ISE

In this study, we conducted a research as to whether splits in shares on the ISE-ON Index at the Istanbul Stock Exchange have had an impact on returns generated from shares between 2005 and 2011 or not using event study method. This study is based on parametric tests, as well as on nonparametric tests developed as an alternative to them. It has been observed that, when cross-sectional variance adjustment is applied to data set, such null hypothesis as “there is no average abnormal return at day 0” couldn’t be rejected through both parametric and nonparametric tests.
Evaluation of Machine Learning Methods in Digital Mapping of Soil Organic Carbon (part of Khorramabad Plain)

Knowledge about the spatial distribution of soil organic carbon (SOC) is one of the practical tools in determining sustainable land management strategies. During the last two decades, the utilization of data mining approaches in spatial modeling of SOC using machine learning algorithms have been widely taken into consideration. The essential step in applying these methods is to determine the environmental predictors of SOC optimally. This research was carried out for modeling and digital mapping of surface SOC aided by soil properties ie. , silt, clay, sand, calcium carbonate equivalent percentage, mean weight diameter (MWD) of aggregate, and pH by machine learning methods. In order to evaluate the accuracy of random forest (RF), cubist, partial least squares regression, multivariate linear regression, and ordinary kriging models for predicting surface SOC in 141 selected samples from 0-30 cm in 680 hectares of agricultural land in Khorramabad plain. The sensitivity analysis showed that silt (%), calcium carbonate equivalent, and MWD are the most important driving factors on spatial variability of SOC, respectively. Also, the comparison of different SOC prediction models, demonstrated that the RF model with a coefficient of determination (R2) and root mean square error (RMSE) of 0.75 and 0.25%, respectively, had the best performance rather than other models in the study area. Generally, nonlinear models rather than linear ones showed higher accuracy in modeling the spatial variability of SOC.
Cellulose nanocrystal-based liquid crystal structures and the unique optical characteristics of cellulose nanocrystal films

Liquid crystals (LC) have been found to have many unique characteristics during the last few decades. The liquid crystal phase is ubiquitous in the biological world, as well as in cellulose and its derivatives. Cellulose nanocrystals (CNC), which can obtain the chiral LC phase in aqueous suspension, have been attracting much attention. The unique size and properties of CNC, such as their light weight, special optical properties, non-toxicity, and biocompatibility, etc., have made them widely applicable in diverse fields. This brief literature review introduces the relationship between the LC phase and CNC. Advantages of CNC as a liquid crystal forming material and the preparation of CNC are discussed. The left-handed cholesteric phase structure and the corresponding unique optical properties of CNC-based LC are described in detail. The CNC-based LC aqueous suspension and three stages of forming LC phase are also described. Then, the main reasons accounting for the brittleness and non-uniformity of pristine CNC-based LC are summarized, as well as ways to overcome these problems. Finally, some optical applications of CNC-based LC films in anti-counterfeiting, colorimetric sensors, and composite devices are considered.
À bien y penser : l’effet du visionnement répété de vidéos sur l’opinion relativement à une intervention policière controversée

La multiplication des appareils captant des images de la vie quotidienne permet maintenant de visionner et revisionner ce dont on n’entendait que parler par le passe. L’intervention policiere est un bon exemple : lorsque disponible, l’enregistrement des interventions controversees est presente a repetition, scrute a la loupe et commente par une foule nombreuse et diverse. Une recherche exhaustive n’a toutefois pas permis de trouver d’etudes empiriques portant specifiquement sur l’effet du visionnement repete sur l’opinion relativement a une intervention policiere. Se basant sur la recherche existante sur d’autres objets, le present article vise a tester l’effet du visionnement repete sur l’opinion quant a une intervention policiere avec emploi de la force, le genre d’enregistrement susceptible d’attirer l’attention des medias et donc d’etre vu par le grand public, et de generer des commentaires polarises et polarisants. Deux enregistrements ont ete presentes deux fois a 78 etudiants universitaires, a une semaine d’intervalle, de facon que leurs reponses puissent etre liees. Les resultats laissent fortement entendre que le visionnement repete d’une video a un effet sur l’opinion qu’on s’en fait : les participants avaient une opinion plus favorable envers l’intervention a la suite du deuxieme visionnement.
O outro lado dos ácidos orgânicos e fitogênicos

A produção animal intensiva exige estratégias sanitárias que aliem efetividade e economicidade. A cadeia suinícola exibe produtividade elevada com demandas crescentes no aspecto de saúde animal. A limitação de promotores de crescimento na produção animal gerou a necessidade de substitutos a esses produtos. Os ácidos orgânicos e dos fitogênicos têm sido utilizados com este enfoque, sendo pouco explorados ou pouco conhecidos os vários outros benefícios que desenvolvem. O objetivo desta revisão é permitir que sejam conhecidos de forma plena as características pouco tratadas dos ácidos orgânicos e os fitogênicos, potenciais substitutos dos promotores de crescimento.
Bank Provisioning Behavior, Procyclicality and Capital Management in South-Eastern Europe

Regulators and policymakers pay an increasing attention to the possible pro-cyclical nature of banks’ behavior in provisioning. Loan-loss provisioning practices of banks are perceived as one of the sources of this procyclicality. The main objective of this study is to provide the evidence on procyclical behavior and capital management of banks through loan-loss provisions in South-Eastern European countries for the period 2004 – 2015. Our results show that loan-loss provisions of banks are procyclical; however, there is no evidence to indicate a relationship between loan-loss provisions and capital management. The findings suggest that a dynamic provisioning system would be beneficial if it is implemented in South-Eastern Europe. The results also show an empirical evidence that loan-loss provisions are not used for income smoothing in banks in South--Eastern Europe.
The effects of company characteristics on financial reporting quality – the application
of the machine learning technique

Purpose: The paper aims to determine the level of financial reporting quality (FRQ) in listed companies in Croatia, as an example of a macro-based accounting system with an underdeveloped capital market, and identify company characteristics that affect it. The paper systematizes the existing key knowledge of FRQ. Furthermore, it critically analyses the principles and direction of influence of various qualitative and quantitative as well as financial and non-financial characteristics of a company. Methodology: The empirical analyses involve joint testing of the machine learning technique (MLT) and the economic hypotheses. M5 algorithm is applied to identify the factors that influence the quality of voluntary reporting as well as the direction and intensity of their influence. Results: The results show that profitability, stock market listing duration (in years), and company size positively affect the level and extent of FRQ through voluntary disclosure of information in the annual financial reports of Croatian listed companies. In addition, differences in FRQ between different areas of economic activity and depending on the type of auditor were found. Conclusion: Croatian companies should adopt good reporting practices to meet the requirements of the global market and thus contribute to the improvement of the overall transparency system. The same is expected from the relevant regulatory authorities who should encourage full disclosure. The paper provides several scientific contributions: first, the spatial dimension of the research; second, the comprehensive literature review; and third, the MLT application in the research on FRQ. An important practical implication of these findings is that they will help financial statement users in the economic decision-making process.
The RNA-binding protein RGGA is a sugar-responsive cofactor of the 5'-3' exonuclease XRN4 that post-transcriptionally meditates plant growth

Sugar-regulated gene expression is a ubiquitous mechanism for carbohydrate allocation and utilization by keeping a balance among source and sink organs in plants. Previous studies have shown that excess sugar represses the expression of the genes implicated in photosynthesis and sugar metabolism. However, the mechanism is still largely unknown. Here, we found that the mutant of Arabidopsis RGGA, RGG repeats RNA-binding protein A coding gene, grew faster than wild type (Col-0) in MS medium. In rgga, mRNA half-live of the genes related to sucrose transport and metabolism, chlorophyll synthesis, root development as well as certain transcription factors was obviously longer than those of Col-0. Further study revealed that AtRGGA could interact with 5'-3' exonuclease AtXRN4, and guide it to the target mRNAs for their degradation. When AtRGGA is absent or its interaction domain is deleted, AtXRN4 self can't recognize the target mRNAs, which leads to a dramatically increase in transcript levels of the above gene subsets, and thus promotes the growth of Arabidopsis with exogenous sucrose supply. And only 5-day sucrose supply could trigger the vigorous growth of rgga. These findings suggest that the regulation of mRNA stability mediated by RGGA plays a critical role in sugar suppression, and implicates a possibility to unlock the growth potential by modulating sugar utilization at post-transcriptional level in plants.
Research on electrical capacitance tomography technology used in the insulation detection of power cable joints

The XLPE cable is widely used in AC / DC power transmission, but its joints and other accessories lack of effective quality assessment means after manufacture, which may lead to potential insulation defects. Therefore, it is of great engineering significance to apply electrical capacitance tomography (ECT) technology to the insulation detection of cable joints. In this paper, the finite element software COMSOL is used to establish the model of cable joint and capacitive sensor, and the insulation detection is investigated by simulation. Firstly, the capacitance is measured to calculate the sensitive field, that is the influence of the spatial distribution of the dielectric constant on the capacitance. It is expected that after the sensitivity field distribution is obtained, LBP algorithm is used to calculate the distribution of dielectric constant, and image reconstructions are successfully realized for two kinds of insulation defects in the cable. In the future, an experimental instrument will be built up to detect the insulation of cable joints.
Deadbeat Predictive Current Control for High-Speed Permanent Magnet Synchronous Machine Drives With Low Switching-To-Fundamental Frequency Ratios

This article analyzes the conventional dq-frame model-based deadbeat predictive current control (DBPCC) methods for high-speed permanent magnet synchronous machine (PMSM) drives with low switching-to-fundamental frequency ratios (SFRs). It shows that the state-of-the-art compensation schemes of control delay and rotor movement effect can improve the control performance but the problem still arises at very high speeds with very low SFRs. Therefore, this article presents a novel DBPCC method for high-speed PMSM drives. The proposed method tracks the machine stator flux vector in the stationary frame to achieve deadbeat control of the dq-axis currents. The control delay and rotor movement effect are both precisely considered. Consequently, the control performance and stability of the proposed DBPCC can be guaranteed at high speeds. Extensive simulations and experiments have been performed on a prototype high-speed PMSM drive. The effectiveness of the proposed method and its superiorities against the field-oriented control and the conventional DBPCCs have all been demonstrated.
Local phase transitions in driven colloidal suspensions

ABSTRACT Using dynamical density functional theory and Brownian dynamics simulations, we investigate the influence of a driven tracer particle on the density distribution of a colloidal suspension at a thermodynamic state point close to the liquid side of the binodal. In bulk systems, we find that a localised region of the colloid-poor phase, a ‘cavitation bubble’, forms behind the moving tracer. The extent of the cavitation bubble is investigated as a function of both the size and velocity of the tracer. The addition of a confining boundary enables us to investigate the interaction between the local phase instability at the substrate and that at the particle surface. When both the substrate and tracer interact repulsively with the colloids we observe the formation of a colloid-poor bridge between the substrate and the tracer. When a shear flow is applied parallel to the substrate the bridge becomes distorted and, at sufficiently high shear-rates, disconnects from the substrate to form a cavitation bubble.
