ONE-YEAR FOLLOW-UP OF EXERCISES IN CHILDREN WITH ALLERGIC ASTHMA

Aim:- To study the effect of exercises in childhood allergic asthma, and to reveal their optimal frequency, intensity, and duration, because of missing consensus about them. Material and Methods:- 12 children (age 11.17 Â± 2.69 years) with allergic asthma were followed for one year. At the beginning and the end of the year, they were treated for 10 days with low daily doses of inhaled corticosteroids and exercises (breathing retraining, respiratory muscle training, and musculoskeletal flexibility with posture/balance training). The children and their parents were instructed to continue the same exercises at home as frequently, intensely, and prolong as possible for one year. Standard spirometry was performed four times â€“ at the beginning and the end of the two 10-day treatment courses. The results were recorded as percentages of the actual versus the predicted spirometric parameters. MANOVA with Bonferronis multiple comparison post-hoc tests and Pearsons correlation with multiple regression post-hoc tests were used for the statistical analysis. Results:- The spirometric parameters showed a significant improvement at the end of each 10-day treatment course versus at the beginning (P<0.05), as well as at the end of the year versus at the beginning (P<0.05). There was a significant correlation of the spirometric parameters versus the exercise frequency (P<0.05) and versus the exercise intensity (P<0.05), but not versus the exercise duration (P>0.05). The regression analysis revealed that with increasing the exercise intensity and frequency (at least once daily) the spirometric parameters are improving significantly (P<0.05). Conclusion:- Exercises significantly improve the spirometric parameters in children with allergic asthma. The optimal exercise frequency is at least once daily with high intensity and short duration.
Systematic Literature Review of Social Entrepreneurship Phenomenon: Perspectives and Theoretical Lenses

Social entrepreneurship (SE) is an emerging subject in the field of entrepreneurship research since previous years. However, there has been a significant increase in social entrepreneurship research based on multifaceted literature reviews. Still, this field required more research to mature the concept of social entrepreneurship studies with different dimensions. The established SE literature shows a lack of studies classifying this phenomenon through the theoretical and practical lenses. The current study fills the gap by studying practical and theoretical perspectives of social entrepreneurship. This study used a systematic review spanning 2010 to 2020 to understand social entrepreneurship conceptual and theoretical perspectives. Based on the study findings, poverty reduction, economic growth, social innovation, job creation, and social entrepreneurship orientation is the cluster of social entrepreneurship. This study also describes few theories that explained the social entrepreneurship phenomenon, e.g. social capital theory, institutional theory, economic innovation theory, complex and ecosystem theory, holistic theory of individual decision making, and behavioural entrepreneurship theory in different perspectives; despite these theories, a multidimensional theoretical perspective needs to be discussed to explain social entrepreneurship comprehensively. Moreover, future directions are also suggested in this study to fill the potential in this field.
Have scale effects on cost margins of pension fund investment portfolios disappeared?

ABSTRACT Investment costs of pension funds are crucial for their returns. Consolidation in the pension fund market proceeds continuously, often with cost savings as the main argument. Unused economies of scale in pension fund investment costs, however, have declined over the years to values close to zero, except for very small pension funds. This paper investigates investment economies of scale in the Netherlands and pays special attention to the non-linear relationship between investment costs and sizes of pension funds. Furthermore, investment cost margins are disaggregated into three cost types and into six asset categories. Performance fees are in particular paid for complex asset categories held by large pension funds. They reduce the traditional-scale economy results for the entire portfolio. Cost savings by consolidation is still possible but is very limited.
STATE-OF-THE-ART: A SYSTEMATIC REVIEW OF THE LITERATURE ON FINANCIAL WELL-BEING

This paper aims at presenting a systematic review of the literature based on the state of the art of research on financial well-being. We systematized a research protocol based on the works developed by Tranfield, Denyer, and Smart (2003), Kitchenham (2004), and Zupic and Čater (2015), to contribute to scientific knowledge about financial well-being, consistent with the methodological rigor required in RSL, which resulted in the composition of the research corpus. We search on the Scopus and Web of Science databases. The analysis includes all international publications between 1960 and 2018, comprising a total of 78 articles. Our results show that the financial well-being (demographic and socioeconomic variables, such as sex, ethnicity, age, income, education, and marital status), in addition to behavioral factors (attitude towards debt and financial literacy), may be indicative of theoretical gaps. We also evidenced that researchers have expended efforts on research involving the decision-making process in finance as a factor influenced by the satisfaction of people's lives.
Moving Research on International new Ventures Forward: A Systematic Reviews on Case Studies

Objective : We delve into the rapid internationalization literature to provide a literature review on the most recent empirical research on international new ventures (INVs). We focus on reporting how the literature on INVs has evolved through the lenses of case studies, and we highlight issues on the use of INVs concepts. Method : We conducted a systematic review of 99 case studies articles related to international new ventures published in leading journals in all areas of knowledge within management. We performed a two-cycle coding and a thematic analysis. Main Results : We have found researchers are applying INV and BG concepts interchangeably, thus incorrectly. Scholars have not considered nor discussed the theoretical implications of dropping and adding criteria when selecting cases. We also found the research in INV has thematically evolved as scholars have increasingly studied the post-internationalization moment of these companies. Relevance/originality : We contribute to the INV's literature by demonstrating the theory is now evolving to understand the post-internationalization moment of these companies. We also discuss the implication of selecting cases disregarding the criteria that qualify them as INVs. Theoretical/methodological contributions: Our research contributes with a discussion on the implications of loosely applying the INVs concepts and offers insights on how the literature has evolved.
Komunikasi Instrumental Berbasis Trikotomi Relasi: Kewenangan Interpretasi Penyidik Dalam Menetapkan Seseorang Sebagai Tersangka

Komunikasi instrumental salah satu bentuk komunikasi yang dikembangkan dalam ranah interogasi penyidikan. Model komunikasi instrumental memberikan kekuasaan absolut bagi penyidik untuk mendominasi dan menghegemoni terperiksa, termasuk kekuasaan untuk menetapkannya sebagai tersangka. Guna mencapai tujuannya Penyidik kerapkali memproduksi pengetahuan sebagai bentuk dari kegiatan interpretasi untuk mensituasikan keadaan terperiksa, dan mengabaikan fakta-fakta yang ada. Tindakan absolutisme Penyidik tersebut terlihat dengan jelas dalam proses pemeriksaan perkara pidana dalam Laporan Polisi Nomor: LP/5464/IX/IX/2019/PMJ/Disrekrimum tertanggal 1 September 2019 atas dugaan tindak pidana Pasal 263 KUHP dan Pasal 266 KUHP. Pengabaian fakta hukum tersebut berfungsi sebagai upaya mempertahankan grand narrative (makna tunggal) berbasis prasangka sehingga mereduksi pemaknaan terhadap bukti-bukti yang meringankan dan bersikap non-imparsial. Penelitian ini bertujuan mengkritisi tindakan hukum dari Penyidik yang menggunakan komunikasi instrumental sebagai basis melakukan interpretasi dan membuat keputusan yang bertentangan dengan KUHAP. Adapun metode penelitian yang digunakan dalam penelitian ini adalah metode penelitian yuridis normatif dengan menggunakan beberapa pendekatan dari paradigma kritis, khususnya melalui konsep trikotomi relasi melalui pengamatan dan observasi. Adapun hasil dari penelitian ini menunjukan pola komunikasi instrumental melalui kegiatan trikotomi relasi yang memproduksi pengetahuan untuk kepentingan sepihak dan mereduksi makna kewenangan hukum melalui otoritas. Sehingga, memunculkan pelanggaran hak asasi manusia dari pihak yang telah ditetapkan sebagai tersangka.
Mineral formation and sorption mechanisms in marine ferromanganese-rich sediments

The phyllomanganate birnessite is the dominant Mn-bearing phase in oxic marine sediments and through coupled sorption and redox reactions exerts a strong control on the oceanic concentrations of micronutrient trace metals. However, during oxic diagenesis and under mild hydrothermal conditions, birnessite undergoes transformation to the tectomanganate todorokite. The mechanistic details of the transformation are important for the speciation and mobility of metals sequestered by birnessite, and are necessary in order to quantify the role of marine sediments in global trace element cycles. This study provides new insight into the crystallization pathway and mechanism of todorokite formation from birnessite under conditions analogous to those found in marine diagenetic and hydrothermal settings. Using a combined approach employing X-ray diffraction, electron microscopy, infrared spectroscopy, X-ray absorption spectroscopy and wet chemical methods, I propose a new four-stage process for the transformation of birnessite to todorokite, beginning with todorokite nucleation, then crystal growth from solution to form todorokite primary particles, followed by their self-assembly and oriented growth via oriented attachment to form crystalline todorokite laths, culminating in traditional crystal ripening. Furthermore, the results of this study indicate that contrary to current understanding, the bioessential trace metal Ni impedes the transformation of birnessite to todorokite, and is eventually released into sediment porewaters. This mineralogical transformation may therefore provide a benthic flux of Ni and possibly other micronutrient trace metals to seawater. Finally, I find that the uptake of Ni to the phyllomanganate birnessite under varying physiochemical conditions is accompanied by Ni stable isotope fractionation. During fractionation, the light Ni isotope is preferentially sorbed to birnessite, leaving the remaining solution heavy with respect to its Ni isotopic composition. These findings raise important questions about the mechanisms and processes responsible for the heavy δ60Ni isotopic compositions recently measured in marine ferromanganese-rich sediments.
Eigenvector statistics of Lévy matrices

We analyze statistics for eigenvector entries of heavy-tailed random symmetric matrices (also called Levy matrices) whose associated eigenvalues are sufficiently small. We show that the limiting law of any such entry is non-Gaussian, given by the product of a normal distribution with another random variable that depends on the location of the corresponding eigenvalue. Although the latter random variable is typically nonexplicit, for the median eigenvector it is given by the inverse of a one-sided stable law. Moreover, we show that different entries of the same eigenvector are asymptotically independent, but that there are nontrivial correlations between eigenvectors with nearby eigenvalues. Our findings contrast sharply with the known eigenvector behavior for Wigner matrices and sparse random graphs.
A Survey of Big Data Techniques for Extracting Information from Social Media Data

Article history: Received: 10 February, 2021 Accepted: 11 May, 2021 Online: 23 May, 2021 Data mined from social media can be used in a variety of methods. The goal of this paper is to explore some of the various methods of mining data from social media and the different areas of its applications. From the analysis of other studies, it was clear that methods such as text analysis, classification, clustering, mapping, testing/validity methods, regression, and research methods were the overarching themes of the previously done research. Pros, cons, and possible extensions were examined for the current research evaluated in the social media data mining area. At the conclusion of this survey, our research team found that text analysis, sentiment analysis, and support vector machine classifiers were among the most common themes of the research methods in this field. In most cases, multiple methods were attempted for each topic to be able to cross compare results.
Vascular Plant Communities in the Polar Desert of Alert (Ellesmere Island, Canada): Establishment of a Baseline Reference for the 21st Century

ABSTRACT The startling warming of the Arctic is driving important environmental changes, but vegetation responses have been spatially heterogeneous and difficult to predict. In this context, establishing new ecological baselines and initiating monitoring schemes are essential. We conducted systematic plot-based surveys in the polar desert surrounding Alert (Nunavut, Canada). We aimed at (1) identifying distinct plant communities, (2) characterizing community attributes, including diversity and abundance, as well as environmental variables associated with each community, and (3) establishing a georeferenced baseline with permanent field markers allowing robust resurveying. We used hierarchical clustering to categorize cover values of vascular plant species, cryptogams, and ground substrates from 1,320 quadrats (1 m2 each) surveyed in 264 vegetation plots. Five plant communities were identified, with one community associated with each of the barren and mesic habitats, and three communities associated with wetlands. The mean biotic covers were generally higher at Alert (13–98%) compared to other polar deserts in the Canadian Arctic Archipelago. A total of 250 quadrats from 50 vegetation plots were permanently marked, and a database describing all plots is available online. This study improves our understanding of High-Arctic plant communities and establishes an important vegetation monitoring reference at the northernmost permanently inhabited settlement on Earth.
Planar Fluorescence Imaging and Three-Dimensional Reconstructions of Capsule Reaction-Control-System Jets

Planar laser-induced-fluorescence flowfield visualization has been used to investigate reaction-control-system jet flows in the wake of hypersonic capsule reentry vehicles. Pitch, roll, and yaw reaction-control-system jets were all studied. Planar laser-induced fluorescence was used to obtain offbody flow images at planar slices in these flowfields, which are not easily visualized by other techniques, owing to characteristically low gas density. When viewed individually, these slices are shown to provide spatially and temporally resolved information, including the locations and characteristics of turbulent flow structures and the location of the jet flow relative to the vehicle. In addition, ensembles of slices acquired at multiple locations throughout the flowfield are combined using computer visualization techniques to reconstruct the three-dimensional shape of the flow. Collectively, the offbody flow-visualization data set acquired in these tests represents a valuable complement to surface measurements, especially as a basis for explaining otherwise perplexing discrepancies between such measurements and computational fluid dynamics results. The tests described herein were conducted in the 31-Inch Mach 10 Air Tunnel at NASA Langley Research Center.
Simultaneous Estimation Of Ambroxol Hydrochloride And Loratadine In Tablet Dosage Form By Using UV Spectrophotometric Method

A novel, simple, rapid, precise, accurate, cost effective and reproducible spectrophotometric method has been developed for simultaneous estimation of ambroxol hcl and loratadine in combined tablet dosage form. The method employs measurement of absorbance at two wavelengths,308nm and 245nm, of ambroxol and loratadine respectively. Beer s law obeyed in the concentration range of 1050μg/ml and 10-50μg/ml for ambroxol and loratadine respectively. The proposed method is recommended for routine analysis since it is rapid, simple, accurate, and also sensitive and specific. Results of percentage recovery studies confirmed the accuracy of the proposed method. The present uv spectroscopic method was validated following the ICH guidelines.
Recycling of Waste Tyre into Silica-Rubber Compounds for Green Tyre Application

The prevention of detrimental effects to environment, owing to generation of a huge amount of rubber wastes, is a big challenge across the globe that warrants a thorough investigation of recycling and reuses waste of rubber products.In this spirit a sustainable development of a devulcanization process along with the production of value added devulcanized rubber is a task of hours.The present work describes a simultaneous devulcanization and chemical functionalisationprocessof waste solution styrene butadiene rubber (S-SBR). This kind of rubber is generally used as the main polymer component in silica filled tread rubber compounds for high-performance passenger car tyres. As-grown ethoxy groupson the functionalized devulcanized styrene butadiene rubber (D-SBR)are exploited for the coupling between silica and the devulcanized rubber chains. We compare the mechanical and dynamic mechanical performance of D-SBR with that of virgin SBR control composites. Covalently bonding interfaces developed from the pendent ethoxy groups of D-SBR and silanol groups on the silica surface offer a competitive and promising performance of the D-SBR based composites. We conclude that the present approach can be further utilized for the large-scale production of different rubber products with satisfied elastomeric performance.
Target-driven visual navigation in indoor scenes using reinforcement learning and imitation learning

Here, the challenges of sample efficiency and navigation performance in deep reinforcement learning for visual navigation are focused and a deep imitation reinforcement learning approach is proposed. Our contributions are mainly three folds: first, a framework combining imitation learning with deep reinforcement learning is presented, which enables a robot to learn a stable navigation policy faster in the target ‐ driven navigation task. Second, the surrounding images is taken as the observation instead of sequential images, which can improve the navigation performance for more information. Moreover, a simple yet efficient template matching method is adopted to determine the stop action, making the system more practical. Simulation experiments in the AI ‐ THOR environment show that the proposed approach outperforms previous end ‐ to ‐ end deep reinforcement learning approaches, which demonstrate the effectiveness and efficiency of our approach.
Fast polarization QKD scheme based on LiNbO3 phase modulators

An optical scheme for polarization encoding BB84 protocol is described. Fiber electro-optical LiNbO3 phase modulators based on Pockels cells provide both polarization states generation for Alice and basis choosing for Bob at high frequency, requiring low operation voltages (Vπ < 5V). Proposed scheme uses only one laser source, which guarantee the indistinguishability of the pulses and active basis choosing allows the system to have two single photon detectors in contrast to the four in the standard polarization encoding schemes. Two phase modulators compensate each others’ polarization mode dispersion, caused by the natural birefringence of the lithium niobate crystal. The system consists of standard components and has simple configuration. The principle of operation is experimentally demonstrated.
Cross Effect of Exercise, Gender and Level of Sport Expertise on Cognition: Visual Perception, Information Processing and Motor Response

To address several recommendations proposing to cross the impact of different variables on cognitive performance, the objective of this study first is to examine the impact of physical exercise variables on cognitive tasks (visual perception, information processing and motor response) at different level of training. The study was carried out on a sample of 88 participants (experts: n = 29, advanced: n = 30, novices, n = 29) performed the coding decoding test, search symbol and the lead psychomotor tester, in order to assess the variations of cognitive profile, at rest and after bout of handball exercise. The results showed, a higher level of training corresponds to a higher level in visual perception with 301ms, motor reaction time with 170ms and choice reaction time with 472ms for the expert’s group, although novices have a greater range of improvement following the exercise with a respective improvement of 33% and 20.20% in search symbol and coding decoding and a respective decrease in visual perception time, motor response and choice reaction time by 16.18%, 14.42% and 14.10%. Also, the combination of the level of training and exercise attenuates differences on some sensorimotor speed performance between the two sexes. The cross effect affects positively but selectively on certain cognitive functions. Our findings enlighten the sport cognition relationship and suggest using physical and sport activity as a means of stimulating cognitive skills and student development in school and university training programs.
Redes epóxi/amina alifáticas com perspectivas para aplicações cardiovasculares. Propriedades biológicas in vitro Epoxy/aliphatic amine networks with perspectives for cardiovascular applications. In vitro biological properties

This work describes the in vitro biological properties of three epoxy networks based on diglycidyl ether of glycerol (DGEG) cured with poly(oxypropylene) diamine (D230), isophorone diamine (IPD) and 4,4'- diamino-3,3'-dimethyl-dicyclohexylmethano (3DCM). The biological interactions between epoxy polymers and blood were studied by in vitro assays. Studies of the protein adsorption, platelet adhesion, lactate dehydrogenase (LDH) activity and thromboresistance properties are presented. The protein adsorption assays onto polymeric surfaces showed that the epoxy networks adsorbed more albumin than fibrinogen. The results about platelet adhesion, lactate dehydrogenase (LDH) activity and thromboresistance properties indicated that the DGEG/IPD and DGEG/3DCM networks show hemocompatible behavior. In this way, we can assume that these epoxy polymers are blood compatible materials.
