On Actual Maximum Exposure From 5G Multi-Column Radio Base Station Antennas for Electromagnetic Field Compliance Assessment
Authors: Xu Bo , Colombi Davide , Törnevik Christer , Ghasemifard Fatemeh , Chen Jiajia
Published: December 2020

The traditional approach of radio frequency electromagnetic field exposure compliance assessment is highly conservative when applied to radio base station antennas implementing dynamic beamforming. In this paper, an analytical model based on the queuing theory with a hyper-exponential service distribution time is developed to assess the time-averaged actual maximum downlink exposure of 5G multi-column radio base station antennas by taking into account the effects of beam scanning over time in free space. Using the measured antenna radiation patterns, the 5G downlink antenna precoding codebook, and assuming a conservative user equipment distribution, the ratio of the actual maximum exposure to the theoretical maximum exposure with 100% traffic load and 75% time-division duplex downlink duty cycle is found to be less than 0.5 and 0.3 for four-transmitter and eight-transmitter radio base station antennas, respectively. These results show that assuming constant peak power transmission in a fixed direction leads to an overestimate of downlink exposure also from conventional antennas characterized by only a few transmitters in addition to massive multi-input multi-output products.

Macro- and micro-morphologies and conservation status of Hymenorchis javanica (Orchidaceae: Aeridinae): the only representative of the genus in Malaysia
Authors: Besi Edward Entalai , Nordin Farah Alia , Go Rusea
Published: December 2020

Analysis of morphological characters and conservation status were carried out for Hymenorchis javanica from Peninsular Malaysia. Morphology was studied in detail and accompanied by a botanical drawing prior to the correct identification. From most closely related Hymenorchis phitamii found in Vietnam, it differs in the lip ovate-oblong with apex acute and margins entire, and the leaves margins prominently serrulate. Based on the current IUCN criteria, we proposed H. javanica as an endangered species under the threatened category. Judging from the current small population sizes and degraded habitats, H. javanica in Malaysia is threatened by extinction in the wild.
Sędzia między realiami polityczności a imperatywami etycznymi. Odpowiedź na recenzję Mateusza Wojtanowskiego
Authors: Mańko Rafał
Published: December 2020

The project of a critical philosophy of adjudication – the application of the presuppositions of critical jurisprudence to the area of judicial application of law – is, to a large extent, a polemic with Artur Kozak’s project of juriscentrism. Whereas the critical philosophy of adjudication accepts, by and large, juriscentrism’s claims concerning especially the social construction of legal reality, it does not accept the views concerning the determination of judicial decisions by institutional imperatives. Adopting Duncan Kennedy’s conception of the moderate indeterminacy thesis, critical philosophy of adjudication claims that the imperatives following from so-called traditional legal methods cannot be seen as limiting the judge when she needs to decide an intepretive dilemma. What the judge may perceive as resistance, are in fact ideological, political and economic imperatives, only cloaked in legal form. This leads to the conclusion that, in essence, a judicial decision has a political character, because it is never fully determined in an unequivocal manner by legal materials (provisions, precedents, intepretive habits), but it always remains, to a certain extent, open. In consequence, the judge, acting under the reality of the political (i.e. structural social conflicts) should not only follow the imperatives of the lex (legislation) and the ius (legal tradition), but also should abide by moral imperatives. The latter include, on the one hand, the requirement of transparency of legal reasoning (e.g. not concealing the extra-legal factors behind a decision), and, on the other hand, a conscious choice of the ideological premises of the decision. Critical philosophy of adjudication, as an emancipatory project, prefers in this respect a pro-emancipatory stance of the judge, i.e. that she strives to make decisions maximising the actual scope of freedom of the individual and liberating her from any form of domination.
O pięknie w pracy prawnika
Authors: Barszcz Tomasz
Published: December 2020

The article concerns the relationship between beauty and a lawyer’s professional work. I attempt to: 1) discover and describe the activities that are particular of such work as well as are determined by beauty; 2) characterize the way in which beauty determines these activates; and 3) point out ontological reasons of this determination. The reflections do not, however, include all activities which the lawyer’s craft consists in, but are limited to those in the course of which decisions are made. Beauty determines a lawyer’s work via the process of decision-making; and if a decision is conceived as an act of cooperation between intellect and will, then the decision is related to beauty in three ways. First of all, beauty constitutes a sine qua non for finding out the circumstances in which the decision is made. Additionally, beauty suggests to the decision-maker the options as the optimal means to an end. Finally, beauty influences the approval of a decision already made.
Stan wyjątkowy w perspektywie filozofii prawa. Próba definicji
Authors: Adamska Weronika
Published: December 2020

The aim of this paper is to propose a definition of the state of exception within the framework of the philosophy of law. The nature of the state of exception is both a legal and a political one. For this reason, it is a subject of inquiry in various disciplines. As a consequence of its hybrid character, state of exception is hard to define, which leads to definitional scepticism. As a criterial definition is impossible to reach, I believe that it should be replaced with a paradigmatic one. Such a definition should take into account the acquis of, among others, philosophy, history or political science, so that it may apply to different methodological approaches. In order to do so, I present the main definitional groups (state of exception as a normative fact, as a constitutional dictatorship, as a political fact, and as a legal void). Next, using the criteria that are common to all those definitions, I propose and analyse three constitutive elements of the state of emergency: a crisis, a suspension of ordinary laws, and a temporary character of this suspension. The definition I propose can help to assess whether a given state is a form of a state of exception. This is of a particular relevance as emergency laws are nowadays widely discussed in the context of terrorist threats.

Reduction in the anxiety levels was achieved after 4 weeks of intervention with improvement in the visual perceptual ages in the experimental group.
THE INFLUENCE OF ROOM ACOUSTIC PARAMETERS ON THE PERCEPTION OF ROOM CHARACTERISTICS
Authors: Jasińska Alicja , Kin Maurycy
Published: December 2020

The article presents the possibility of identification of rooms on the basis of binaural perception. Results of subjective evaluation were compared with the values of sound strength, G. A previously unknown sound term was introduced: the strength of spatial impression as the inverse of standard deviation of the results obtained. It turned out that the results presenting the sound strength parameter can be correlated with the subjective evaluation of the spatial impression, which is the size of the room. It can be helpful in the process of room identification, probably due to the reverberation impression in the room. Authors plan to continue the study with more rooms and different types of sound sources.
PECULIARITIES OF NON-AUDITORY EFFECTS OF NOISE DEPENDING ON THE DOSE AND PROCESSED AMOUNT OF ACOUSTIC INFORMATION
Authors: Myshchenko Iryna , Kolhanov Anatolii
Published: December 2020

Most of non-auditory effects cannot be explained as a simple consequence of noise energy influence. The level of arousal also depends on predictability of acoustic signals (level of entropy). The present article aims to analyse the contribution of noise dose and the level of entropy in non-auditory effects. 117 metallurgists and 15 healthy non-adapted to noise men were exposed to 4 different combinations of noise dose and entropy (during 8 hour working shift and 1 hour in a soundproof room correspondingly). Experiment was 2x2 factorial design. Functional state of cardiovascular and central nervous system was evaluated before and after exposure. The chosen noise characteristics account for up to 80% of the dispersion of nonspecific effects. The largest number of significant differences were between the groups, where the controlled factors were either at the lower or the upper level of variation. Noise dose and entropy contribute to such non-specific reactions as systolic/diastolic blood pressure, Stress Index, Kerdo index, duration of RR intervals, visual/hearing motion time delay. The cardiovascular system is the most sensitive to the variation of the entropy of the acoustic field.

Published: December 2020

Air Table merupakan alat  pemisah mineral berharga (konsentrat) dengan mineral pengotor  (middling) berdasarkan prinsip perbedaan berat jenis dan ukuran menggunakan media udara. Permasalahan muncul karena middling yang dihasilkan masih mengandung konsentrat dan kadar middling relatif tinggi sehingga middling perlu dilakukan proses kembali. Dalam mengatasi hal itu perlu dilakukan pengaturan variable (setting) antara lain kemiringan, hal ini untuk meningkatkan perolehan konsentrat agar dapat mengoptimalkan waktu dan biaya operasional. Penelitian ini bertujuan menganalisis pengaruh kemiringan meja Air Table terhadap kadar Sn konsentrat dan recovery yang dihasilkan. Proses pengolahan  menggunakan 2 (dua) percobaan dengan sample yang berbeda menggunakan variasi kemiringan 2,81o, 3,37o dan 3,94o  sedangkan variabel tetapnya yaitu  frekuensi pukulan 590 pukulan/menit dengan panjang pukulan 8mm, tekanan udara untuk air blower 1,5 atm dan diameter lubang feeder 1 cm.  Hasil penelitian menunjukan kecenderungan makin besar sudut kemiringan Air Table maka kadar Sn akan semakin tinggi, sedangkan recovery cenderung semakin rendah. Kedua percobaan menunjukan hasil yaitu recovery tertinggi diperoleh pada kemiringan 2,81o sedangkan kadar Sn konsentrat tertinggi diperoleh pada kemiringan 3,94o .

Published: December 2020

In the article, on the basis of generalization of the results of the ascertaining research, the features of professional deformations in young teachers and teachers with a long work experience were studied. For this purpose, the total sample was divided into two groups. The criteria for destructive professional changes were determined, which were: the age of the teacher, the experience of professional and pedagogical activity, the components of the “mental burnout” syndrome (emotional exhaustion, depersonalization, reduction of personal changes), the general level of professional personality deformation and the level of professional stress. The structural features of the “mental burnout” syndrome, the general level of professional deformation and stress have been established empirically. With the help of correlation analysis, the relationship between various destructive personality changes in each of the groups of teachers under test was established.

The article examines the consequences of the reform of the Russian electric power industry, which resulted in the formation and operation of: wholesale electricity markets in the European part of the country, including the Urals, and in Western Siberia; the system of state-owned companies transporting electricity; and the aggregate of market platforms for the retail electricity market. New phenomena are analyzed, in particular: the emergence of vertically integrated companies coordinating the production and combustion of fossil fuels in power plants; the emergence of competition in the heat market from the side of heat generating plants, which led to financial losses for the existing CHP plants that are part of heat generating companies - participants in the wholesale electricity market; the withdrawal of some heat consumers from the market and the construction of their own heat generating plants; failure to create a competitive retail electricity market. Measures are proposed to prevent the negative consequences of the detected phenomena.
