Decomposition of a 1,3,5-Triamino-2,4,6-trinitrobenzene Crystal at Decomposition Temperature Coupled with Different Pressures: An ab Initio Molecular Dynamics Study

We performed ab initio molecular dynamics simulations to investigate the initiation mechanisms and subsequent decompositions of a 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) crystal at initial decomposition temperature coupled with different pressures. The initial decomposition step of TATB was found to be the unimolecular intramolecular hydrogen transfer; moreover, this initiation mechanism is independent of the variation of the pressure. However, the intramolecular hydrogen transfer becomes easier to occur when the pressure increases from 1 to 3 GPa and from 4 to 5 GPa, while the situation is just the opposite with the increment of pressure from 3 to 4 GPa and from 5 to 20 GPa. The pressure accelerates subsequent decomposition of TATB with the increase of pressure from 1 to 3 GPa and from 4 to 5 GPa, while it would decelerate the decomposition when the pressure increases from 3 to 4 GPa and from 5 to 20 GPa. The deceleration of the pressure on the decomposition of TATB may be caused by inhibiting initia.
On the Melt Rheological Behavior and Microstructure of Nanoclay-Filled Polyethylene/Ethylene Vinyl Acetate (PE/EVA) Blend

Correlation of rheological response with microstructure and also the tensile mechanical properties of nanoclay-filled polyethylene/ethylene vinyl acetate blends were studied. From transmission electron microscopy observations, the same clay localization within polyethylene- and ethylene vinyl acetate-rich blends was revealed. However, a better clay dispersion in the ethylene vinyl acetate-rich blend was found by analyzing the changes in the linear viscoelastic rheological properties discussed by the fractional Zener model and the power law expression. The clay influences on the tensile properties of polyethylene- and ethylene vinyl acetate-rich blends were in good agreement with its microstructure, implied by the rheological studies.

The effect of institutional differences on the economic development of German-speaking countries

The growth rates and sustainability of economic development of five German-speaking countries: Austria, German Democratic Republic (GDR), Luxembourg, Federal Republic of Germany (FRG) and Switzerland in the period 1947-1990 are investigated. The comparison is carried out for five economic cycles of the united Germany over this period. The indicators of the standard deviation of the growth rates of real GDP and national income are used as a sustainability performance. It is revealed that the GDR’s institutional system showed in a sustained way high growth rates, and after the isolation of West Berlin – favorable risks and firmness of prices. This system may even be regarded as the best institutional model of economic development for the German nation. At the moment of accession into the blocs, the member countries of the military and political bloc obtained benefits of development; during the exacerbation of the military and political situation, Switzerland, which was far from the contact of the blocs, became the winner, and during the detente – border Austria. Countries with smaller economies demonstrated greater institutional mobility.
Government Size and Quality of Governance: Does State Size Matter?

Purpose: Small state studies has emerged as a discipline, and this discipline has been initially dominated mainly by the issues of vulnerability and a lack of capacities of small states, although these issues have been gradually replaced by the discussions on the potential opportunities of small states, not just their challenges. Within this framework, the consideration needs to be done also on the effect of the state size on the economics, governance and public management, among others. Design/methodology/approach: The current theorizing in small state studies focuses on the specifics of the small economy modelling and governance. The existing economic literature has occasionally stressed the relations between the size of the state and size of government, but with rather mixed empirical results. Moreover, relations between state size and quality of governance has also been emerging issue. This study would like to integrate both approaches. The empirical research utilizes cross-national comparative investigation based on the data for 44 European states; and we specifically assess, in addition to the existing approaches, how budgetary and non-budgetary scope of government differentiates among smaller and larger states. Findings: The results of the study suggest that the effect of the size of the state does not necessary favour larger states in respect to the smaller size of government and quality of governance. Thus, although potential scale economies matter regarding the public services’ provision, the structure of spending, institutional context, and innovations in public service delivery modes also have the role in shaping scope and functions of the government, whereas quality of governance seems to be independent regarding the state size, at least in the European context. Research limitations/implications: Analysis is limited to the cluster of European states, and the results should be interpreted within this context. Originality/value: After the World War II the number of states has increased substantially, in fact, it has tripled. We are currently living in the era of small states, as more than one third of the existing two hundred and more states around the globe are actually small, if we assess the multiple criteria combination. In this context, this paper would like to add to the development of the field of small state studies.
Development of a radioscandium immunoconjugate for radioimmunotherapy

Abstract Developing monoclonal antibodies labeled with beta-emitters has led to the introduction of important agents in radioimmunotherapy. In this work, Sc-46 chloride was obtained by thermal neutron activation flux of natural metallic scandium sample followed by dissolution in acidic media (radionuclidic purity via beta and gamma ray spectroscopy, 99.9% ; radiochemical purity via ITLC, >99%) and used in radiolabeling of rituximab after conjugation with DOTA-NHS-ester. The specific activity was however not high. The conjugates were purified by molecular filtration and used in the radiolabeling. The radiochemical purity (ITLC), stability studies (ITLC and size exclusion chromatography), determination of average number of DOTA conjugated per mAb (chelate: antibody ratio, 5.8:1) and gel electrophoresis of [ 46Sc]Sc-DOTA-anti-CD20 were determined followed by biodistribution studies for 46Sc and [ 46Sc]Sc-DOTA-anti-CD20 i n wild type rats up to 72 h. The binding of the radiolabeled antibody was showed to be 60% on Raji cells. The final compound was stable in presence of PBS at 37 ºC and room temperature. The accumulation of the radiolabeled antibody in liver, spleen, kidney, heart and other tissues demonstrates a pattern similar to the other radiolabeled anti-CD20 immunoconjugates. The present study shows the possibility of antibody labeling for future use in radioimmunotherapy by 47Sc.
The Effects of Narrative and Movie Therapy on the Theory of Mind and Social Functioning of Patients with Schizophrenia.

Introduction The objective of this study was to investigate the effects of narrative therapy (NT) in which the patients tell their own life story in a group environment, and the movie therapy (MT), which is an interaction-based, emotion-themed, culturally compatible video screening activity, on chronic schizophrenia patients' theory of mind abilities, psychopathology, and social functioning. Method Thirty patients with schizophrenia were included in this study. At the beginning of the study, 2 patients dropped out as they started to work in a job. Participants were randomly assigned into two groups: one group received NT, and the other had MT. Dokuz Eylül Theory of Mind Index (DEToMI), Reading the Mind in the Eyes Test (RMET), Social Functioning Assessment Scale (SFAS), the Positive and Negative Symptoms Scale (PANSS), and Montreal Cognitive Assessment Scale (MoCA) were applied to the patients before and after the study. Pre- and post-test results within the group were compared via Wilcoxon test. Mann-Whitney U and mixed-design ANOVA were used for group comparisons regarding treatment efficiency. Results In the NT group, PANSS negative and general psychopathology, DEToMI, SFAS, and MoCA scores significantly increased. In the MT group, PANSS negative, DEToMI, SFAS, MoCA, and RMET scores significantly enhanced. Regarding the comparisons for before and after the treatment, it was found that mean RMET scores and DEToMI faux pas sub-scale scores were higher in the MT group comparing to the NT group. Conclusion This study suggests that NT and MT could be beneficial on different domains of the theory of mind, and may lead to a decrease in psychopathology, and increase in neurocognition and social functioning. MT might be a more effective treatment in the field of perceptual theory of mind.

The treatment process of an extremely rare giant borderline phyllodes tumor of breast: case report and literature review

Giant phyllodes tumors are rare fibroepithelial neoplasms, usually defined as >10 cm. It is often difficult for pathologists to distinguish fibroadenomas from phyllodes tumors and determine the malignant potential level. The current treatment principle is to ensure the extended resection of tumors with a margin of 1 cm or more. For patients with multiple local recurrences or large tumors after surgery, simple mastectomy is recommended. Axillary management should be considered when breast cancer is diagnosed at the same time. We now present a rare case: a female patient found a right breast mass in 2014, and the mass had continued to grow for more than 7 months, and she was ultimately diagnosed with a giant phyllodes tumor with a diameter of 30 cm. Extensive resection is a suitable method to treat smaller phyllodes tumors, but giant phyllodes tumors require mastectomy, so the patient in this case underwent a total mastectomy. We removed the mass completely without destroying the normal tissue and structure. The treatment effect was obvious, and no related adverse events occurred during or after the operation, the postoperative recovery was good, and the patient was discharged once she was verified to be in a stable condition. This case is the first reported case of a patient who had a giant borderline phyllodes tumor with a diameter of 30 cm, underwent total mastectomy, and was followed up for 6 months without recurrence. The long-term effect of the treatment will be further evaluated after 5 years.
Limited implementation of the Nordic hamstring exercise in professional and semi-professional soccer

Background/Purpose: In soccer players, non-contact injuries are most common, especially hamstring muscle injuries, which can be prevented by the Nordic hamstring exercise (NHE). This study assessed the professional and semi-professional soccer players and coaches’ awareness, implementation, and opinion of the NHE efficacy in reducing hamstring injuries. Methods: A questionnaire regarding the awareness, implementation, and opinions of the NHE’s efficacy in reducing hamstring muscle injuries was distributed. Results: The survey was completed by 812 (88.3% male and 11.7% female) players and coaches. Of these, 395 (48.6%) were aware of the NHE, and 355 (43.7%) implemented it in their current practice. Those implementing NHE had a positive opinion about its efficacy in reducing hamstring injuries. Conclusion: Further efforts and research are warranted to increase the international awareness and implementation of the NHE and educate soccer players and coaches about the importance of its implementation and effectiveness in preventing hamstring injury.
Thermoelectric properties of single-wall carbon nanotube films: Effects of diameter and wet environment

The Seebeck coefficient S and the electrical resistivity ρ of single-wall carbon nanotube (SWCNT) films were investigated as a function of the SWCNT diameter and carrier concentration. The S and ρ significantly changed in humid environments through p-type carrier doping. Experiments, combined with theoretical simulations based on the non-equilibrium Green’s function theory, indicated that the power factor P can be increased threefold by the enrichment of semiconducting SWCNTs, but the nanotube diameter has little effect. The improvement of the film resistivity strongly enhances the film thermoelectric performance, manifested as increasing the value of P above 1200 µW/(m·K2).
Structural Assessment of FML Aerostructures with Integrated Electromagnetic Features

A substantial contribution to reduce the aerodynamic drag and consequent CO 2 and NO x emissions is to integrate communication antennas in the aircraft structure. This paper presents a GLARE fuselage panel design for an integrated VHF slot antenna and discusses the results of a mechanical experimental campaign on a structural element level, in quasi-static tensile conditions. The tested specimens showed small variability in terms of stiffness and strength (typical for GLARE), little dependence on the ambient conditions, damage presence, and layup configurations and good agreement with early numerical simulations. In addition, stiffness and strength predictions, based on empirically found design values seem to correlate well with the found test values.
Food choice motives of generation Z in Serbia

The topic of this paper is food choice motives of generation Z in Serbia. Generational cohort is used as a theoretical perspective, as the research is focusing on specific generational cohort. The aim of this research is to understand the characteristics of generation Z and their food choice motives. A Food Choice Questionnaire (FCQ) was used for analyzing generation Z’s motives. A survey was used for data gathering. The sample consists of 287 students, from three universities from Serbia. The results are presented based on descriptive statistics, statistical testing and principal component analysis. The most important food choice motives identified are: sensory appeals, health and nutritional food attributes and convenience of preparation. The study revealed that generation Z in Serbia has some common features, as recognized in developed countries, but shows one interesting divergence, regarding the undervaluation of ethical factors. Managerial implications from the perspective of a marketing strategy are discussed. © 2021 EA. All rights reserved.
Maturity, Variety and Origin Determination in White Grapes (Vitis Vinifera L.) Using near Infrared Reflectance Technology

Soluble solids content, variety and origin of grapes are three relevant features to determine wine quality. Soluble solids content is directly related to ripeness. The capacity to certify the origin or variety of a grape is of major interest for wine makers. The aim of this paper was to study whether near infrared reflectance (NIR) spectroscopy could be used to determine soluble solids content and to identify different varieties and origins of grapes. Samples of Viura and Chardonnay grapes were collected in two locations (Cadreita and Villamayor de Monjardin) which varied in environmental conditions. Mass and sugars content measured by a refractometer and NIR (800–500 nm) reflectance spectra were obtained. A partial least squares regression (PLS) was made to calibrate the NIR spectra. The regression models for Chardonnay grapes were more robust than for Viura grapes, showing coefficients of determination for calibration and validation of 0.75 and 0.70 and a standard error of cross-validation of 1.27. Therefore, NIR technology is suitable to determine the soluble solids content although it requires a calibration model for each variety, using a large number of data points and variables. The combined variety model showed a residual predictive deviation of 1.33, while Viura and Chardonnay models showed 1.54 and 1.88, respectively. The results of discriminant analysis using variables from the NIR spectrum showed a percentage of well-classified grapes according to the variety to which they belonged of 97.2% and a 79.2% of well-classified Chardonnay grapes according to their origin. In conclusion, NIR technology is a useful alternative for identifying the variety and origin of grapes.
Emerging Economies’ Institutional Quality and International Competitiveness: A PLS-SEM Approach

The home country’s institutional framework determines the capacity to compete in the global arena. This paper discusses the linkage between institutional quality (IQ) and international competitiveness (IC). We measured institutions’ quality in emerging economies through the use of selected indicators between 2007–2017. To evaluate the proposed IQ constructs and their relationship with IC, we applied partial least squares – structural equation modeling (PLS-SEM) analysis. The model outcomes suggest that political and lack of systemic conditions have a significant and negative effect on international competitiveness, while science, technology, engineering and mathematics (STEM) resource conditions have a significant and positive effect.

Bayesian Nonparametric Object Association for Semantic SLAM

Semantic simultaneous localization and mapping (SLAM) can provide the foundation for robots to perform more advanced tasks than traditional geometric SLAM. Object association is a crucial factor in semantic SLAM. Previous work utilizes observations at the current moment and a single geometric feature to associate objects. The number and measurement of objects change over time. The ambiguity of object association reduces the performance of semantic SLAM. In this letter, we present a Bayesian Nonparametric model approach for object association. The temporal Dirichlet process mixture (TDPM) model is introduced to provide prior information. We couple the evolution of time with the object association, which considers the influence of historical association information on the current association results. Besides, we propose a Multi-Rules Likelihood (MRL) model to eliminate the ambiguity of object association by considering multiple object properties. We validate our approach both in simulation and real data from the KITTI dataset. The experimental results show that our approach improves the performance of object association and semantic SLAM.
Effect of solid phase transformation on the solubility product of thorium hydrous oxide at 363 K

ABSTRACT The solid phases and solubilities of thorium(IV) hydroxide after aging at 363 K were investigated in the pHc range of 2–8 in NaClO4 or NaCl solutions having a 0.1–3.0 mol/dm3 (M) ionic strength. Sample solutions containing solid amorphous thorium hydroxide (Th(OH)4(am)) were prepared by the oversaturation method, and stored in a temperature chamber kept at an aging temperature (Ta) of 363 K for specified periods. The sample solutions were then cooled to 298 K for measurement of the apparent solubilities. The apparent solubilities, after aging at Ta = 363 K, decreased about 3 orders of magnitude from the solubility of Th(OH)4(am) at Ta = 298 K. The solid phases were investigated by X-ray diffraction (XRD) in order to determine the particle sizes in the thorium hydroxide solid phases. A slight growth of the particle size of the solid phases after aging at Ta = 363 K was suggested from the obtained XRD spectrum and was correlated to the decrease of the apparent solubility at Ta = 363 K based on the particle size effect of the solubility product.
Anthropometry, food consumption and iron deficiency anemia, among primary school children (6-15 years) in Kenitra city (North-Western Morocco)

Introduction the problem of malnutrition among children is a phenomenon associated with a rapid nutrition transition in Morocco and all developing countries. The objective of this study is to evaluate the nutritional status by anthropometry, food consumption and iron deficiency anemia among primary school children aged 6-12 years in Kenitra city (Morocco). Methods the survey covered 271 students (55% of boys and 45% girls) aged 6 to 12. Information concerning food consumption patterns, socioeconomic status and other lifestyle factors was obtained using questionnaires and interviews. Anemia was defined when haemoglobin < 11.5 g/dl. Results the results showed that, 6.3%, 2.2% and 17.3% children were stunted, thin and overweight respectively. No significant association was found between gender and nutritional status of children. 16.2% children were anemic and food consumption found not to be varied and below recommendations. Conclusion the finding in this study showed that overweight and obesity occurred more frequently than the various forms of under nutrition in the population studied. The finding support the urgent need to improve the nutritional status of children by implementing preventive strategy for the problem of malnutrition among school-aged children.
