AESTHETIC ASSESSMENT OF FOLK DANCES UDC 793

Dance, as a form of art and physical exercise, has a very significant role for humankind. Through performance of movements accompanied by music, man expresses his emotions, thereby "radiating" energy affecting both him and the world around him. Each nation has its own distinctive customs, which are priceless. By honoring and perpetuating the traditions of their ethnicity, men and women from Serbia have used dancing as a tool for seduction and expression of love for the opposite sex. In producing this work, we conducted a study using semantic differential, where we utilized a scale of assessment of aesthetic impression (Pejic, 2007). Research was conducted on a sample of 40 (20 female and 20 male) third year students of the Faculty of Sport and Physical Education in Belgrade. The aim of the research is to reveal relationships between the sexes, as well as the aesthetic assessment of folk dances from different ethnocoreologic areas in Serbia, according to aesthetic dimensions of harmony, semantic depth, evaluation, activity, and decoration. Regardless of the influence of the folk dances from different ethnocoreologic areas of Serbia, the results of the research indicate that female participants have a higher assessment of folk dances only on the basis of harmony and evaluation. Once we looked past the role of gender of the participants and focused on the assessment of folk dances from different ethnocoreologic areas in Serbia, we noticed differences between folk dances from different ethnocoreologic areas in dimensions of harmony, semantic depth, evaluation, and activity. The interaction between the participants' gender and the folk dances from different ethnocoreologic areas was spotted solely in the dimension of semantic depth.
3D Printed Ultrastretchable, Hyper-Antifreezing Conductive Hydrogel for Sensitive Motion and Electrophysiological Signal Monitoring

Conductive hydrogels with high stretchability can extend their applications as a flexible electrode in electronics, biomedicine, human-machine interfaces, and sensors. However, their time-consuming fabrication and narrow ranges of working temperature and working voltage severely limit their further potential applications. Herein, a conductive nanocomposite network hydrogel fabricated by projection microstereolithography (PμSL) based 3D printing is proposed, enabling fast fabrication ability with high precision. The 3D printed hydrogels exhibit ultra-stretchability (2500%), hyper-antifreezing (-125°C), extremely low working voltage (<100 μV), and super cyclic tensile stability (1 million cycles). The hydrogel-based strain sensor can probe both large-scale and tiny human motions, even with ultralow voltage of 100 μV at extremely low temperature around −115°C. It is demonstrated that the present hydrogels can be used as a flexible electrode for capturing human electrophysiological signals (EOG and EEG), where the alpha and beta waves from the brain can be recorded precisely. Therefore, the present hydrogels will pave the way for the development of next-generation intelligent electronics, especially for those working under extremely low-temperature environments.
Inertial Impactors to Measure Aerodynamic Diameters of Man-Made Organic Fibers

It is widely accepted that the aerodynamic diameter of a particle is one of the main factors that determines particle deposition into the human respiratory system. The determination of aerodynamic diameter of spheres or near spherical objects is routinely accomplished using impactors. The aerodynamic diameter of man made organic fibers (MMOF), on the other hand, has not traditionally been measured using impactors, because fibers of the same cross section may have different lengths and a variety of shapes (straight, curved, etc.) for each length. The aerodynamic size of the fibers is thus a function of fiber orientation. Single and multiple stage impactors have been developed, calibrated, and validated specifically for the determination of the aerodynamic diameter of large fibers with circumscribed diameters between 20 and 35 w m and an aspect ratio ranging from subfiber lengths (aspect ratio < 3) up to 40. The impactor allows measurements of the aerodynamic diameter of cellulose acetate fibers released during mechanical smoking of cigarettes. The performance characteristics were evaluated by spherical particles of known diameters, fibers of known length and diameter, and computational fluid dynamic calculations. Our methodology has shown that inertial impactors can be used to determine the aerodynamic diameter of large cellulose acetate fibers.
Splitted Neural Networks for Equipment Inspection: Experiments and Resources

—This paper presents a feasibility study of performing equipment inspection on networked environments by exploring networks specially designed for semantic segmentation task. It is assumed that the neural network needs to be split and the resulting two pieces need to be allocated in two devices. The provided results suggest that the current state of the art on semantic segmentation is not well-suited for the splitted networks applications even in the context of the 5G networks.
Gill surface interaction model for trace-metal toxicity to fishes: role of complexation, pH, and water hardness

A model has been developed to account for the variability in trace-metal toxicity to fishes at different values of alkalinity, hardness, and pH. The model utilizes trace-metal speciation, gill surface interaction, and competitive inhibition to predict effective, toxicant concentration (ETC). Copper, cadmium, lead, and zinc bioassay data have been utilized.
New insights into the electrochemical performance of Li2MnSiO4: effect of cationic substitutions

The performance of the Li2MnSiO4 cathode material is hindered by voltage decay and capacity fading caused by structural instability. To rationalize the origin of such structural instability, we have investigated a total of 142 Li2yMnSiO4 configurations at y = 0.125, 0.25, 0.333, 0.375, 0.417, 0.5, 0.625, 0.666, 0.75 and 0.875 by density functional theory methods. It is found that the most stable Li2yMnSiO4 configurations with y ≤ 0.5 consist of Mn4+ and Mn3+ in octahedral or five-fold coordination. This induces a crystal deformation, loss of the orthogonal symmetry, and a notorious volume decrease (7% for LiMnSiO4 and 14% for Li0.5MnSiO4). The effect of Mn substitution on the crystal structure of the delithiated silicates Li0.5Mn0.75M0.25SiO4 is computationally investigated for M = Mg, Fe, Co and Ni. The most stable configurations for Mg, Fe and Co substitutes possess Mn4+ in octahedral coordination, sharing edges with the adjacent Si and Mn polyhedra. DFT results suggest that among the studied substituents, only Ni could help to maintain the structural integrity of the delithiated samples. Experimentally, Li2Mn1−xNixSiO4 samples with x = 0, 0.1 and 0.2 were synthesized and electrochemically tested.
Utilization of PV Solar Farm as a STATCOM in a Distribution Networking

PV solar farms produce power during the day and are completely idle in the nights. This paper presents utilization of a PV solar farm as a STATCOM in a distribution networking to compensate the voltage level. A reference voltage is fixed in the comparator, then it compares two voltage signals and determines the drop voltage.PIC16F877A microcontroller is used to provide the pulse signal to the IGBT inverter to turn switch on and off based on coding. According to the switch condition the solar energy is used to improve the voltage level. This STATCOM functionality will provide the voltage regulation and improves the stability and transfer limits far beyond minimal incremental benefits.
A Distributed Reactivity Model for Sorption by Soils and Sediments. 4. Intraparticle Heterogeneity and Phase-Distribution Relationships under Nonequilibrium Conditions

Rates of phenanthrene sorption by four different types of soils and sediments were characterized by examining the time dependence of solute phase distribution relationships (PDRs) in completely-mixed batch reactors. Unlike conventional single-level concentration methods, the experiments were conducted using a range of concentrations to obtain a time series of nonequilibrium PDRs for each sorbent−sorbate system over reaction periods ranging from 1 min to 14 days. In all cases tested, the nonequilibrium PDRs changed from approximately linear form to increasingly nonlinear form as the time of reaction increased. A Freundlich-type relationship, q(t) = KF(t)C(t)n(t), was used to relate values of measured temporal solid-phase solute concentrations, q(t), to corresponding solution-phase solute concentrations C(t). After a short “initiation” stage, the parameters n(t) and KF(t) were observed to vary functionally with logarithmic time.

Investigation of Phytochemical, Antioxidant Activity and Antimicrobial Activity of Vitis repens

The present research deals with the phytochemical screening, elemental analysis, antioxidant activity and antimicrobial activity of Vitis repens Wight & Arn. Phytochemical screening of Vitis repens Wight & Arn. was performed to examine the different types of phytoconstituents present in the powder sample of Vitis repens Wight & Arn. It was observed that these tests show the presence of alkaloids, carbohydrate, glycosides, phenolic compounds, saponins, starch and tannins in this sample. α-amino acids, flavonoids and reducing sugars were not observed in Vitis repens Wight & Arn. Elemental analysis of the Vitis repens Wight & Arn. sample was characterized by EDXRF method. It was observed that Ca (76.8 %) and K (21.3 %) as major inorganic constituents and Ti (0.646 %), Mn (0.393 %), S (0.154%), Fe (0.142 %), Si (0.127 %), Mg (0.127 %) and P (0.108 %) as minor inorganic constituents. The antioxidant activity using DPPH assay method with Ascorbic acid standard, expressed as IC50 value was observed 25.72 ppm. The antimicrobial activity of some crude extracts (ethanol and water) of Vitis repens Wight & Arn. was screened by agar-well diffusion method against six organisms such as Bacillus subtilis, Staphylococus aureus, Pseudomonus aeruginosa, Bacollus pumilus, Candida albicans and Escherichia coli. It was observed that pseudomonas aeruginosa showed both ethanol and water extract.
A Unified Distributed Cooperative Control of DC Microgrids Using Consensus Protocol

In this work, we propose an effective and simple control approach for islanded DC microgrids that allows each distributed generator (DG) to achieve accurate voltage regulation and power-sharing. An improved dynamic consensus protocol, which is robust to measurement noise and states initialization, is employed to enable each agent to locally calculate the average bus voltage with a sparse cyber network. On this basis, we propose a cooperative controller that merges the voltage regulation and power-sharing objectives in a unified fashion. The proposed approach only uses neighbors’ voltage information to regulates the average bus voltage to its nominal value while maintaining proportional power-sharing or optimal power dispatch. This significantly simplifies its implementation and reduces the communication bandwidth requirement. A global model of the DC microgrid considering the cyber network is established in the form of a state-space-model, where the reference voltage vector corresponds to the input and the average bus voltage vector denotes the state. Then, the input-to-state stability analysis is carried out. To the end, comprehensive hardware-in-the-loop (HiL) tests are conducted to validate the effectiveness of the proposed control strategy. The proposed control strategy exhibits plug-and-play capability, and it is resilient to message update rate and communication failure.
Increasing resident participation in waste management through intrinsic factors cultivation

BACKGROUND AND OBJECTIVES: Resident participation in waste management is essential to overcome waste problems effectively. In many developing countries, the local government has been struggling to encourage resident involvement in the waste management process, but the participation rate is still low. Thus, it requires a system that can encourage residents to participate effectively and sustainably. Therefore, this study aimed to determine what determinant factors, either extrinsic or intrinsic, significantly improve resident participation by changing behaviour toward waste management.METHODS: This study tried to get insights from previous studies about key determinant factors affecting resident behaviour toward waste management to improve participation, significantly using a literature review method.FINDINGS: Educational setting for residents is crucial to improve waste management participation by cultivating key intrinsic factors with support from extrinsic factors that lead to changing behaviour. This study identified eight types of key contents shared in the educational setting to ensure its improvement. Key intrinsic factors should be cultivated, including six kinds of knowledge and five emotional domain factors. The six critical types of knowledge include technical experience, waste management performance knowledge, perception of benefits, environmental awareness, understanding of individual and social responsibility, and understanding the social norms and regulations. The five intrinsic factors in the emotional domain include environmental efficacy, motivation, personal moral norms, PBC, and Attitude toward waste management. All the critical determinant factors, including intrinsic and extrinsic factors, should support each other to improve residents’ behaviour, leading to sustainable participation.CONCLUSION: Relevance of educational content to the residents is crucial to ensure educational intervention effectiveness. With full support from the antecedent factors, waste management behaviour can be nurtured sustainably, significantly increasing the participation rate. Combining extrinsic and intrinsic factors is recommended to ensure the effectiveness of the improvement of resident participation.
Amygdalin content in the seeds of several apricot cultivars

Eight different cultivars of apricots (Prunus armeniaca L) have been studied regarding the amygdalin content of their seeds to correlate amygdalin content with known phenotypes to determine if the inheritance of this trait is controlled in a discrete or quantitative manner. HPLC determination of amygdalin showed large differences between cultivars with sweet and bitter kernels. Also, some significant differences within groups of bitter and sweet kerneled cultivars were found but they did not correlate with the phenotypical expression of kernel flavour. From the results it is concluded that bitterness seems to be controlled in a discrete manner and that organoleptic evaluation that classifies cultivars or seedlings as bitter or sweet would be enough with no need for chemical analysis. © 1998 SCI.
Reactions of nitrogen dioxide with hexenes. The mechanistic and structural factors controlling the product composition

The reaction of nitrogen dioxide with a number of hexenes has been investigated using several solvents and the major products have been identified. The heterolytic reaction path has been effectively eliminated by the use of hexane as solvent. The mechanism of the heterolytic reaction path is discussed with the aid of ab initio molecular orbital calculations on possible nitrosating agents with particular reference to the syn and anti forms of nitrosyl nitrate. A new mechanism is proposed for the formation of certain trisubstituted derivatives.
The effects of bracing on sagittal spinopelvic parameters and Cobb angle in adolescents with idiopathic scoliosis: A before-after clinical study

Objectives This study aims to evaluate the effects of bracing on the Cobb angle and sagittal spinopelvic parameters in adolescent idiopathic scoliosis (AIS) patients. Patients and methods A total of 25 adolescents (2 males, 23 females; mean age 12.7±1.6; range, 10-15 years) with AIS who received bracing between January 2000 and June 2017 were retrospectively analyzed. The initial and final out-of-brace radiographs of 25 AIS patients were analyzed with regard to the spinopelvic parameters. The pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), Cobb angle, thoracic kyphosis (TK), and lumbar lordosis (LL) were measured. Results The mean age at the initiation of bracing was 12.7±1.6 years. The mean initial Cobb angle was 31.8°±5.9°. There were no statistically significant differences between the baseline and the final measurements of the PI, PT, and SS. However, there were statistically significant differences between the baseline and the final measurements of the TK, LL, and Cobb angle. A significant correlation was observed between the PI and Cobb angle and TK and between the LL and SS. Conclusion Our study results show significant associations between the sagittal pelvic parameters and the spinal parameters during the brace treatment of adolescents with idiopathic scoliosis.
The kinetics of internal energy randomisation in thermal unimolecular reactions

The aim of this paper is to present a minimal theory of thermal unimolecular reactions, including explicitly the kinetics of intramolecular randomisation processes. A quasi-diatomic model is formulated and, within the framework of the model, both first-and second-order randomisation processes among reactant and product states are examined.It is concluded that a vital mechanism for the intramolecular energy randomisation in thermal unimolecular reactions is a collisional one. On this assumption, a straightforward derivation of the Polanyi–Wigner specific rate function, as we have reinterpreted it, becomes possible.At the same time, anomalies in the fall-off curves for the thermal isomerisations of methyl isocyanide and ethyl isocyanide can be accounted for very simply: in the former case, values for both the first- and second-order randomisation rate constants can be derived, but in the latter case it is only possible to establish a lower limit for the second-order randomisation rate constant.
Reconstructing Chinese Nationalism and National Identity in Digital Popular Culture: A Case Study of My People My Country

In this paper, we focus on investigating the discursive strategies appropriated and the new connotations of Chinese nationalism and national identity advocated in the recent Chinese national blockbuster My People My Country (MPMC). Relying on political discourse analysis as the research framework, we find that Chinese nationalism and national identity propagated in current age have shifted from traditional victimization and humiliation towards pride and happiness. To effectively propagate these new connotations, Chinese intellectuals draw on a myriad of acoustic and visual resources and disseminate political ideologies from two perspectives: propagating through emotionalization and entertaining through commercialization. Specifically, MPMC makers incorporate multimodal semiosis to construct an imagined Chinese national identity and achieve emotional mobilization. The presence of different entertaining elements de-politicizes the ideological persuasion and enhances propaganda effects.
Morphologic Mapping and Analysis of Tsiolkovsky Crater Ejecta

Introduction: Tsiolkovsky crater is an elliptical (~200km diameter major axis, by ~180 km diameter minor axis) complex impact structure centered at (129oE, 20oS) on the far side of the Moon. Tsiolkovsky is distinct from other impact craters on the lunar far side due to the presence of a mare deposit overlying much of the crater floor [1], and what has been shown to be an exceptionally rocky surface texture covering parts of the crater rim and ejecta blanket [2]. This structure has been shown to have an age of ~3.2 Ga [2] and is remarkably well preserved due to a lack of subsequent impact cratering in the region. Here we have used high resolution images and topographic datasets derived from instruments on the Lunar Reconnaissance Orbiter (LRO) to map in detail the locations and extent of various distinct ejecta facies. The type, distribution, and stratographic relationships of these ejecta facies provide insight into the formation and emplacement behavior of the Tsiolkovsky ejecta, which in turn provides insight into the formation of other impact structures, the interaction of ejecta with preexisting topography, and their influence on the origin and evolution of planetary crusts. Methods: We used ~100 m/pixel Lunar Reconnaissance Orbiter Wide Angle Camera (LROC-WAC) images [3] along with elevation data derived from the Lunar Orbiter Laser Altimeter (LOLA) [4], in order to characterize the surface morphology of the Tsiolkovsky ejecta deposits. Four facies of ejecta were identified based on their morphologies (i.e., texture, relative tonality and structures) as well as documenting their surface area, geographic setting, and stratigraphic relation to one another. Using the Java Mission-planning and Analysis for Remote Sensing (JMARS) program [5], shapefiles were drawn to encompass areas expressing distinct surface morphologies and complied to form a complete geomorphologic map of the crater and ejecta [Fig. 1]. Results and Facies Descriptions: Facies A. Facies A extends outward in all directions from the crater rim to radial distances of between ~50km to ~270km. This facies is characterized by a series of groove textures oriented radially to the crater center. Facies A material is observed to overprint preexisting topographic features around Tsiolkovsky. This facies covers a total surface area of ~130,000km. Facies B. Facies B is identified as distinct chains of similarly sized circular depressions oriented radially from the crater centre. These chains are overlain by material from Facies A where the two facies coincide, but are not completely infilled by Facies A material. These features become more well-defined the more distant they are from the crater centre, especially beyond the extent of Facies A.
Variations in bacterial counts during the production of frozen green beans

Summary The viable counts of total aerobic mesophiles and psychrophiles, coliforms, coagulase-positive staphylococci and salmonellae in green beans were greatly reduced by blanching in the course of their preparation for freezing. The increase in bactcrial numbers between blanching and freezing appears to be caused by contamination from the conveyor belt and from the hands of employees. Salmonellae, detected in small numbers prior to blanching, were not recovered after blanching. Freezing at a rate of 4–5°C per min, had only a slight destructive effect on the various bacterial groups studied. A significant reduction in counts, especially of coliforms and staphylococci, occurred after 4 weeks of frozen storage. Aerobacter aerogenes was the main coliform organism recovered from the frozen green beans.
Chemical Applications of Metastable Argon Atoms. III. Production of Krypton and Xenon Metastable Atoms

An inexpensive experimental technique has been developed for the production of argon, krypton, and xenon metastable atoms using a discharge‐flow system. The reactions of these metastable atoms with N2, CO, and N2O were investigated in the pressure range 0.3–10 torr, and the emission spectra resulting from the reactions were identified. These spectra gave information about the collision event and also about some of the relaxation processes. Franck–Condon factors apparently do not control the molecular excitation processes in collisions of excited heavy atoms with light diatomic molecules. This discharge flow source of metastable atoms provides emission spectra of sufficient intensity from added CO and N2O for study of emission bands which currently are not well understood. Molecular emission from N2O has been observed, apparently for the first time.
