Рассматривается пассивная радиочастотная метка, которая находится на гибкой подложке, что приводит к появлению проблемы с изменением характеристик при изгибе метки. В процессе исследования производилось моделирование для трех ситуаций: плоской метки, изогнутой внутрь и наружу. Благодаря современным методам электродинамического моделирования возможно определить все основные характеристики RFID метки - в активном режиме: обратные потери, диаграмму направленности; в пассивном режиме: диаграмму обратного рассеяния, токи и напряжения в нагрузке. При моделировании были построены графики зависимости амплитуд токов и напряжений в нагрузке от частоты, пиковые значения эффективной площади рассеяния. Благодаря полученным данным можно определить наиболее оптимальные частоты для облучения RFID метки, чтобы обеспечить ее работу в активном режиме (высокие токи и напряжения в нагрузке), а также в режиме обнаружения - большие значения ЭПР. Приводятся графики и таблицы для сравнения исследуемых случаев, по которым видны изменения характеристик при изгибе метки, что делает невозможным применение системы в широких диапазонах частот, так как стоит учитывать ее возможные изгибы
The article discusses a passive RFID tag that sits on a flexible substrate, which leads to a problem with changing characteristics when the tag is bent. In the course of the study, we carried out modeling for three situations: a flat tag, curved inward and outward. Thanks to modern methods of electrodynamic modeling, it is possible to determine all the main characteristics of an RFID tag - in the active mode: return loss, radiation pattern; in passive mode: diagram of backscatter, currents and voltages in the load. During the simulation, we plotted graphs of the dependence of the amplitudes of currents and voltages in the load on frequency, peak values of the effective scattering area. Thanks to the data obtained, it is possible to determine the most optimal frequencies for irradiation of an RFID tag in order to ensure its operation in an active mode (high currents and voltages in the load), as well as in the detection mode - large ESR values. The article provides graphs and tables for comparing the cases under study, which show changes in characteristics when the tag is bent, which makes it impossible to use the system in wide frequency ranges, since its possible bends should be taken into account

MEMBANGUN KOMPETENSI ABAD 21 MELALUI METODE CONSTRUCTIVE CONTROVERSY PADA PEMBELAJARAN BAHASA INGGRIS
Authors: Wahyuni Leny Sri 
Published: January 2021

This study aims to describe an image of cooperative learning model application through constructive controversy method in building 21st century competencies towards English learning. This study uses descriptive qualitative which took place at the second grade of SMKN 1 Talaga, Majalengka. Collecting data is done by using observation, interview, and documentation. The results illustrate that the ability to communicate, collaborate, think critically, and creatively in students can be built through controversial issues which make them challenged to discuss actively, intensively, and comprehensively. The use of 'gambits' in form of asking and giving opinions is quite effective to encourage students to analyze (communicate actively and effectively) related to the issues raised, collaborate intensively on various ideas to make decisions, and formulate solutions by constructing ideas from various results of divergent thinking. Keywords: 21st century competencies; English learning; cooperative learning model; constructive controversy method; controversy issues

, strongly lensed, red galaxy at z = 1.883 ± 0.001. While the global photometry and spatially resolved outskirts of MRG-S0851 imply an early formation scenario with a slowly decreasing or constant star formation history, a joint fit of 2D grism spectroscopy and photometry reveals a more complex scenario: MRG-S0851 is likely to be experiencing a centrally concentrated rejuvenation in the inner ∼1 kpc in the last ∼100 Myr of evolution. We estimate 0.5 ± 0.1% of the total stellar mass is formed in this phase. Rejuvenation episodes are suggested to be infrequent for massive galaxies at z ∼ 2, but as our analyses indicate, more examples of complex star formation histories may yet be hidden within existing data. By adding an FUV color criterion to the standard U–V/V–J diagnostic—thereby heightening our sensitivity to recent star formation—we show that we can select populations of galaxies with similar spectral energy distributions to that of MRG-S0851, but note that deep follow-up spectroscopic observations and/or spatially resolved analyses are necessary to robustly confirm the rejuvenation of these candidates. Using our criteria with MRG-S0851 as a prototype, we estimate that ∼1% of massive quiescent galaxies at 1 < z < 2 are potentially rejuvenating.
Turbulence and Particle Acceleration in Shearing Flows
Authors: Rieger Frank M. , Duffy Peter 
Published: January 2021

Abstract
We explore constraints imposed by shear-driven instabilities on the acceleration of energetic particles in relativistic shearing flows. We show that shearing layers in large-scale AGN jets are likely to encompass a sizeable fraction (≳0.1) of the jet radius, requiring seed injection of GeV electrons for efficient acceleration. While the diffusion process may depend on predeveloped turbulence if injection occurs at higher energies, electron acceleration to PeV and proton acceleration to EeV energies appears possible within the constraints imposed by jet stability.

Authors: Navaneetha K.P  , Sunil Kumar S  , Kusumam Joseph  
Published: January 2021

Diabetic retinopathy (DR) is a leading cause of acquired vision loss in middle-aged and elderly people globally. In modern science, other than the meticulous control of diabetes there is no proven non-invasive management for the prevention or cure of Diabetic retinopathy.
In this study, mild to moderate Non-proliferative diabetic retinopathy (NPDR) with retinal haemorrhages is considered as a Timira (symptomatically) and as Abhishyanda (considering etiopathogenesis) with Kapha-pitta predominance. Mridweekadi kashaya, predominantly Kapha Pitta samana, was selected for the study to be used as Seka.
Method: The study design was Interventional- pre and post evaluation without control, sample size fixed as 30 eyes. Mridweekadi kashaya was used as Seka for 21 days, twice daily. Fundus photographs were taken prior to commencement of Seka, on the 22nd day and then on 30th and 60th day after completion of the procedure. Change in extent of retinal hemorrhages were assessed as visualized in Fundus photographs and direct ophthalmoscopy. Change in visual acuity was assessed by LogMar Visual acuity chart and change in contrast sensitivity by Pelli-Robson contrast sensitivity chart consecutively, prior to the treatment, on the 10th day, 22nd day and then on 30th and 60th day after completion of procedure. Statistical analysis was done using Wilcoxon signed rank test and Paired t test according to the variable.
Result: Control in retinal haemorrhages associated with NPDR and improvement in visual acuity and contrast sensitivity.
Conclusion: Mridweekadi kashaya seka is effective in controlling retinal haemorrhages associated with NPDR.
Community Satisfaction to Corporate Social Responsibility (CSR) Programs for Rural Economic Empowerment
Authors: Sugiarto Mochamad , Sulaiman Adhi Iman 
Published: January 2021

This study aims to analyzing the implementation of a cement manufacturer’s CSR programs to improve effectiveness and satisfaction of people in general. The research conducted using survey method to 86 respondents, who are members of Joint Business Group in Cilacap Regency and beneficiaries of Corporate Social Responsibility (CSR) programs. The data were collected through observation, questionnaires, interviews and discussions, then used descriptive statistical analysis and qualitative narrative. The research results have found that the company’s direct involvement model in a CSR program gives several advantages. Nevertheless, the limited quantity and quality of this cement manufacturer’s CSR administrators result in less effective planning, assistance and evaluation processes. People are satisfied with how the CSR is executed by the cement manufacturer, yet the program they carry out has not completely matched what these people need and cannot correctly identify the CSR program beneficiary targets. In relation to this, the implementation of CSR using direct involvement model needs some improvement to make it more effective and intensive. The modification of direct involvement model by use of information technology becomes an important alternative to deal with the limited quantitaty and quality of human resources of CSR program administrators.
Perception of St. Valentine’s Day in the Culture Space of Latvia
Authors: Kovzele Oksana 
Published: January 2021

Under the contemporary social and economic conditions, no culture can stay “sterile”. Growth of Internet communication and globalization processes facilitates borrowing of new realia including festivities and festive traditions and their circulation in the global culture environment. One of such realia that has become extremely widespread in Europe and the whole world is St. Valentine’s Day. Recent research literature regards it in various aspects (psychological, feminist, commercial, etc.); researchers are also interested in the experience of celebrating St. Valentine’s Day in diverse regions and countries. The present paper aims at characterizing the specificity of perceiving St. Valentine’s Day in Latvia on the basis of newspaper, magazine, almanac articles available to readers in the course of 70 years (since the 1950s till nowadays). On the basis of article content analysis, the paper marks the trends characteristic of Latvian society in treatment of St. Valentine’s Day under different historical, political, and economic conditions, Latvians being in their homeland and/or in exile. The compiled materials show that St. Valentine’s Day entered Latvian culture space and got rooted there only after regaining state independence – in the 1990s and especially in the 21st century. Nowadays it is represented in various spheres of public life, yet the residents’ reaction to this phenomenon that is still foreign to many is rather ambiguous. St. Valentine’s Day is not only associated with love and romance but is treated as a tool that yields commercial profit for traders, whereas for others it causes needless expenses, depression, and disappointment.

On the ice-nucleating potential of warm hydrometeors in mixed-phase clouds
Authors: Krayer Michael , Chouippe Agathe , Uhlmann Markus , Dušek Jan , Leisner Thomas 
Published: January 2021

Abstract. The question as to whether or not the presence of warm hydrometeors in clouds may
play a significant role in the nucleation of new ice particles has been debated
for several decades. While the early works of Fukuta and Lee (1986) and
Baker (1991) indicated that it might be irrelevant, the more recent
study of Prabhakaran et al. (2020) suggested otherwise. In this work, we
attempt to quantify the ice-nucleating potential using high-fidelity flow
simulation techniques around a single hydrometeor and use favorable considerations
to upscale the effects to a collective of ice particles in clouds. While we find that ice nucleation
may be significantly enhanced in the vicinity of a warm hydrometeor
and that the affected volume of air is much larger than previously estimated, it is
unlikely that this effect alone causes the rapid
enhancement of ice nucleation observed in some types of clouds, mainly due to the low
initial volumetric ice concentration. Furthermore, it is demonstrated that the excess nucleation
rate does not primarily depend on the rate at which cloud volume is sampled by the meteors'
wakes but is rather limited by the exposure time of ice-nucleating particles to the wake,
which is estimated to be of the order of few microseconds. It is suggested to further investigate
this phenomenon by tracking the trajectories of ice-nucleating particles in order to obtain
a parametrization which can be implemented into existing cloud models to investigate second-order effects
such as ice enhancement after the onset of glaciation.
