Published: August 2021

Background: High-impact trauma frequently leads to injuries of the orbit, but literature focusing on the viscerocranium rather than the neurocranium is underrepresented. Methods: Retrospective cohort study (2006–2014) at an urban level 1 trauma center assessing the frequency and typical patterns of orbital injuries on whole-body computed tomography (WBCT) with maxillofacial multi-slice CT (MSCT) after severe trauma. (1) Screening of consecutive WBCT cases for dedicated maxillofacial MSCT. (2) Examination by two independent experts’ radiologists for (peri-/)orbital injuries. (3) Case review for trauma mechanisms. Results: 1061 WBCT were included revealing 250 (23.6%) patients with orbital injuries. Less than one-quarter (23.3%) of patients showed osseous and 9.5% showed soft tissue injuries. Combined osseous and soft tissue lesions were present in 39.2% of orbital injuries, isolated soft tissue injuries were rare. Single- or two-wall fractures of the orbit were prevalent, and the orbital floor was affected in 67% of fractures. Dislocated extraocular muscles (44.6%), deformation of the ocular globe (23.8%), and elongation of the optic nerve (12.9%) were the most frequently soft tissue findings. Vascular trauma was suspected in 15.8% of patients. Conclusions: Orbital trauma was confirmed in 23.6% of cases with suspected facial injuries after severe trauma. Concomitant soft tissue injuries should be excluded explicitly in cases with orbital fractures to prevent loss of vision or ocular motility.
Diatom Epibionts on Amphipod Crustaceans: A Possible Vector for Co-introductions?
Authors: Desiderato Andrea , Beermann Jan , Haddad Maria Angelica , Fernandes Luciano Felicio
Published: August 2021

Epibiotic associations can result in co-introductions of non-indigenous species, which may affect ecosystems in several ways. In fouling communities of three estuaries in southern Brazil, a number of amphipods was found to harbour a dense coverage of epibionts. Three different species, the two globally widespread caprellids Caprella equilibra and Paracaprella pusilla, as well as the ischyrocerid Jassa valida, had been colonised by diatoms. Further scanning electron microscope analyses assigned these diatoms to 14 different species that had previously been reported from benthic habitats. This is one of the scarce records of diatoms attached to amphipods. The occurrence of the diatom Amphora helenensis represents the first report for Brazilian waters as well as the second record for the whole SW Atlantic Ocean. As some diatoms were associated with common fouling amphipods, a possible regional spread aided by these crustaceans seems likely. Possible effects of this amphipod-diatom association on the animals and their implications for the underlying ecosystems of this remain to be elucidated.
Wood Retention at Inclined Bar Screens: Effect of Wood Characteristics on Backwater Rise and Bedload Transport
Authors: Schalko Isabella , Ruiz-Villanueva Virginia , Maager Fiona , Weitbrecht Volker
Published: August 2021

In forested mountain catchment areas, both bedload and large wood (LW) can be transported during ordinary flows. Retention structures such as sediment traps or racks are built to mitigate potential hazards downstream. Up to now, the design of these retention structures focuses on either LW or bedload. In addition, the majority of LW retention racks tend to retain both LW and bedload, while bedload transport continuity during ordinary flows is an important aspect to be considered in the design. Therefore, a series of flume experiments was conducted to study the effect of LW accumulations at an inclined bar screen with a bottom clearance on backwater rise and bedload transport. The main focus was put on testing different LW characteristics such as LW size, density, fine material, and shape (branches and rootwads), as well as a sequenced flood. The results demonstrated that a few logs (wood volume of ≈ 7 m3 prototype scale with a model scale factor of 30) are sufficient to reduce the bedload transport capacity to below 75% compared to the condition without LW. Fine material and smaller wood sizes further reduced bedload transport and increased backwater rise. In contrast, LW density and LW shape had a negligible effect. The test focusing on a sequenced flood highlighted the need for maintenance measures to avoid self-flushing of the bed material. The results of this study further indicate that an inclined bar screen may need to be adapted by considering LW characteristics in the design of the bottom clearance to enable bedload continuity during ordinary flows.

Legal and social consequences of bankruptcy of legal entities
Authors: Maksimova Olga Anatolievna
Published: August 2021

In this challenging time, when the economic situation is unstable, many companies have to face such a phenomenon as bankruptcy. The procedure is new for our country and, therefore, its implementation is associated with a number of difficulties and issues. Bankruptcy sometimes turns out to be the only civilized way for a legal entity to solve the problem of accumulated debts. This procedure allows reorganizing or liquidating a business in compliance with the interests of the owner and creditors. Bankruptcy as a civil procedure has its own legal and social consequences, fi rst of all, when it comes to the workforce and threats to lay off the organization's staff . As a rule, bankruptcy affects the personnel of an organization or an enterprise and, in this case, it becomes extremely important to respect the labor rights of members of the labor collective at all levels. Dismissal of employees during the liquidation of an enterprise must be carried out strictly in accordance with the articles of the Labor Code of the Russian Federation. The contractual relationship is terminated in stages. Certain categories of workers are of great importance — people with disabilities, pregnant women, underage employees, mothers and fathers involved in raising children without a second parent, etc.
Engineering of semiconductor nanocrystals and metal Ions in amorphous materials
Authors:   , Mada Radha
Published: August 2021

Semiconductor nanocrystals (NCs), metal ions containing glass based materials have applications in design engineering, and may solve many technological problems. P2O5 based glasses are an important class of materials for several applications, especially for high power laser. Recently, the construction of semiconductor NCs-based phosphate glass materials has been shown to be of high importance for various applications, like in photovoltaics, LEDs, lasers and spintronics. The major challenges are the intentional insertion of dopants into semiconductor NCs aiming expanding their intrinsic functionalities and the scalable incorporation of NCs into host free of hydroxyl and organic species for stabilizing and integrating their performances. On the other hand, the low refractive index of phosphate glass can be adjusted by the addition of a high index of TeO2 content. These hybrid materials fulfil the requirement of refractive index contrast for chromatic dispersion control and are useful for the design of photonic materials. The thesis focus on the design of ZnNiTe semiconductors in transparent phosphate glass-ceramics, and the effect of TeO2 environment in Nd3+ doped phosphate glass for optoelectronic and solid-state laser applications. The structural features of these materials have been determined by XRD, FT-IR and Raman spectroscopic techniques. Optical properties were characterized by using UV-Vis-NIR absorption and fluorescence spectroscopic techniques. The findings were used to estimate crystal field interaction parameters, coordinate state of Ni2+ ions, Judd-Ofelt intensity parameters for Nd3+ ions and radiative properties of metal ions in glasses. Thermal diffusivity (D) and thermal conductivity (K) of ZnNiTe NCs in glasses were determined using thermal lens (TL) and thermal relaxation (TR) techniques. The results revealed that the behaviors of D and K for the studied samples are similar. Nonlinear optical properties of ZnNiTe NCs glasses were also studied using Z-scan technique. The nonlinear refractive property is observed only in the sample containing 5% Ni. Other samples with 1.0% to 10% of Ni content presented nonlinear absorption nature. This suggests that the absorption coefficient, β does not change significantly with the wavelength, but increase with Ni concentration, with confinement effects and two-photon absorption (TPA).
Guerreiros de Cristo, bailarinos de Jeová: uma etnografia sobre ritualística reteté e política do sobrenatural em um contexto de favela
Authors:   , Pereira Réia Sílvia Gonçalves
Published: August 2021

A partir da análise dos dados etnográficos colhidos em 2018, o trabalho analisa a atuação dos pentecostais na favela Corredor das Cores, em Campos dos Goytacazes, norte do Rio de Janeiro, território dominado pela facção narcotraficante Terceiro Comando Puro (TCP). Na favela, por ordens da facção, as possibilidades de exercício religioso são restritas às manifestações pentecostais. Assim, a pesquisa se concentrou na análise de uma das igrejas existentes naquele contexto, a Águas Divinas. A partir do estudo, argumenta-se que denominações pentecostais como a igreja pesquisada compõem uma face de uma religiosidade de cunho popular e encantado, no qual a experiência pentecostal influencia e é influenciada pelas dinâmicas relacionais das camadas populares. Nesse movimento, destacam-se o espírito bélico, o ethos heroico e o que denomino como política do sobrenatural. Foram redigidos quatro capítulos. No primeiro, a favela é apresentada a partir do domínio da facção narcotraficante Terceiro Comando Puro (TCP) e da relação com as manifestações pentecostais, que naquela localidade, assumem contornos específicos, formando pequenas igrejas com rituais conhecidos, em expressão êmica, como reteté de Jeová. No segundo capítulo, são apresentadas lideranças religiosas que, ao manejarem as expressões do sobrenatural pentecostal, exercem papeis políticos e de negociação ante o TCP e aos demais moradores. No terceiro capítulo, são abordados os conflitos na igreja analisada, conflitos esses, muitas vezes, ensejados pelas relações de gênero. A intenção é destacar que, além das redes de solidariedade observada pela literatura sobre as vivências pentecostais em contextos populares, os conflitos e as disputas também compõem o enredo das relações travadas. No quarto capítulo, uma reflexão mais detida sobre as cerimônias da igreja, destacando o caráter emocional e sinestésico dos rituais, compreendidos aqui como lócus importantes de investigação por hiperbolizarem as relações sociais mais amplas. Dessa forma, a igreja Águas Divinas se insere e conforma o contexto racializado, marcado pela pobreza e pela violência da encantada favela Corredor das Cores.

Dayak onions (Eleutherine palmifolia Merr) are a potential commodity that has many health benefits, so it has a high economic value. However, this Dayak onion plant has not received much attention in cultiva¬tion technology, especially fertilization. So far, this onion has grown relying on nature, while the land has diminished its fertility. This study tested a combination of chicken manure and NPK fertilizer to obtain the optimal composition to increase the productivity of Dayak onions. This study used a factorial randomized block design with 3 replications. The first factor consists of the treatment of chicken manure(O1 = control, O2 = 10 ton.ha-1 and O3 = 20 ton.ha-1). The second factor consists of NPK fertilizer(K1 = control, K2 = 100 kg.ha-1 Urea + 150 kg.ha-1 SP 36 + 200 kg.ha-1 KCl, K3 = 200 kg.ha-1Urea + 150 kg.ha-1 SP 36 + 200 kg.ha-1 KCl, and K4 = 300 kg.ha-1 Urea + 150 kg.ha-1 SP 36 + 200 kg.ha-1 KCl). The results showed that there was an interaction effect between the composition of chicken manure and NPK on the number of leaves, fresh weight of tubers, and dry weight of tubers per clump but did not affect the growth of plant height. The yield of Dayak bulbs of 62.60 g / clump was obtained in the composition of chicken manure of 20 tonnes.ha-1 with an NPK of 200 kg.ha-1 Urea + 150 kg.ha-1SP 36 + 200 kg.ha-1 KCl. From an economic perspective, the composition is very efficient and feasible, which is indicated by R / C> 1, namely 5.75, which means that with a certain unit cost, it can get 5.75 times the revenue.

l: l: Email:l: Email:l: Regarding the highly contiguous novel coronavirus disease (COVID-19), it is unsafe for health professionals, being involved in a hospital isolation ward. The healthcare workers, stationed in a contagious ward provide relentless monitoring of specific health parameters of those patients. The rate of contagion proportionately depends on the time spent by the health workers in an isolation ward. This challenging task is fairly manageable by employing promising Internet-of-Things (IoT) based autonomous robots (i.e. smart bots) thus reducing the hazards of contamination to health workers. In this research paper, we introduce a smart bot that can periodically measure the health parameters of COVID-19 patients, for instance, body temperature, oxygen saturation levels, blood pressure, respiration rate, heart rate, blood glucose level, etc. The proposed smart bot will transfer from one patient to another in a structured pattern and autonomously collect, forward, store the data of the patients for further analysis. The goal of the work is to involve a significantly inferior number of health workers in contagious wards to control contagion, thus creating stress-free environs for health workers. Moreover, smart bots will offer health professionals to pay attention to non-COVID-19 patients and make things easier for regular health check-ups of individuals in need.

Power Quality Improvement using UPQC with Single and Three-Phase Non-linear Loads in Countryside Areas
Authors:   B.Tech. in Electrical and Electronics Engineering UP Technical University, India., Vishnoi Shuchi
Published: August 2021

This paper is intended to simulate a power quality conditioning device, Unified Power Quality Conditioner (UPQC), in countryside areas for non-linear loading. From past decades there is much increase in the requirement of the good quality electrical power in single phase distribution grids established in these locations. Due to technical advancement, three-phase loads are practiced more than single phase loads so that the demand for three phase distribution grids is growing. But the installation process of three-phase grids, at countryside areas, is not an economic option and to get access to these systems is a very challenging task. So a neighbouring three-phase distribution system is required to be established at the location, where single-phase to three-phase UPQC with single wire earth return is appropriate for the end user due to economic considerations. A dual compensation strategy is implemented to obtain the reference quantities for controlling the converters. The proposed idea is accomplished to eliminate voltage harmonics and mitigate further instabilities and power quality problems. This system allows the balanced and regulated voltage with lower harmonic content. Synchronous Reference Frame (SRF) based controllers are considered to organize the input grid current and the load voltages of the UPQC. The present prototype under consideration analyses and validates the compensation and controlling techniques using PI controller. The control strategies are simulated using MATLAB/SIMULINK.

The current study investigates the effect of masking of mental images with congruent and incongruent picture-stimuli among the students of Architecture and Humanities. Students from these two streams were chosen (N=60, mean age = 19 yrs.). Participants were shown a list of concrete words and were urged to make mental images. The images made by the participants were covered by the Experimenter by the congruent and incongruent pictures. The effect of masking was compared among the high and low imagery usage participants. Two t tests were computed to understand the significant differences between the means. A non-significant t of 1.031 was obtained for the high imagery expert group while, a significant t of 4.699, p < 0.001 with df 58 was seen for low imagery expert group. Additionally, a two-way ANOVA was computed followed by Tukey’s post-hoc test to understand the difference in the overall recognition scores between the high and low imagery usage groups, the effect of masking on memory, and the interaction effect of both the variables.

In wireless sensor networks(WSN) ,authentication of messages is the highly important function in preventing threats from un wanted , un authorized and corrupt messages from being sent. There are various message verification and authentication methods have been proposed as well as developed based on cryptography technology such as symmetric key cryptographic systems or public-key cryptographic systems. Also there are many different techniques available based on polynomial-based schemes, elliptic curve cryptography (ECC) and so on. All the above said methods have its own merits and demerits. In this research work a new method of authenticating the message by its IP and MAC address (together encrypting) and analysing the encrypted message to find the authenticity of the message and the node which has sent the message at collecting node will be carried out.

Authors: Trimurtiningrum Retno
Published: August 2021

Semen adalah salah satu material utama penyusun beton yang mempunyai dampak negatif terhadap lingkungan. Produksi semen berkontribusi terhadap lepasnya gas emisi CO2 pada atmosfer. Berbagai inovasi dilakukan untuk membuat beton lebih ramah lingkungan, dengan tujuan untuk mengurangi kebutuhan semen. Abu sekam padi merupakan hasil olahan limbah penggilingan padi yang mempunyai sifat pozzolan sehingga dapat digunakan sebagai bahan pengganti sebagian semen. Pada penelitian ini digunakan variasi prosentase abu sekam padi sebanyak 0%, 4%, 6% 8% dan 10% terhadap berat semen yang digunakan untuk menggantikan proporsi semen dalam campuran beton. Hasil pengujian menunjukkan bahwa workabilitas berkurang dan nilai resapan cenderung meningkat seiring bertambahnya prosentase abu sekam padi pada campuran. Kuat tekan maksimum diperoleh campuran yang mengandung 8% abu sekam padi yaitu sebesar 25,03 MPa.
A Non-Reversible Privacy Preservation Model for Outsourced High-Dimensional Healthcare Data

Published: August 2021

Privacy preservation of high-dimensional healthcare data is an emerging problem. Privacy breaches are becoming more common
than before and affecting thousands of people. Every individual has sensitive and personal information which needs protection
and security. Uploading and storing data directly to the cloud without taking any precautions can lead to serious privacy breaches.
It’s a serious struggle to publish a large amount of sensitive data while minimizing privacy concerns. This leads us to make
crucial decisions for the privacy of outsourced high-dimensional healthcare data. Many types of privacy preservation techniques
have been presented to secure high-dimensional data while keeping its utility and privacy at the same time but every technique
has its pros and cons. In this paper, a novel privacy preservation NRPP model for high-dimensional data is proposed. The model
uses a privacy-preserving generative technique for releasing sensitive data, which is deferentially private. The contribution of this
paper is twofold. First, a state-of-the-art anonymization model for high-dimensional healthcare data is proposed using a generative
technique. Second, achieved privacy is evaluated using the concept of differential privacy. The experiment shows that the proposed
model performs better in terms of utility.
A Low Complex Algorithm for Detection of Sleep Apnea from ECG Signals using Sliding SSA Combined with PCA, KPCA, and SPPCA
Authors: Zubair Muhammad
Published: August 2021

Sleep apnea is a potentially life-threatening sleep condition in which breathing stops and resumes repeatedly. It is caused by breathing pauses during sleep, which leads to frequent awakenings. As we all know, computational time and efficiency are essential in the healthcare industry; to address this issue, we proposed an algorithm that performs more computations in less time without compromising the machine learning model’s performance. This study employs a unique technique called Sliding Singular Spectrum Analysis (SSSA) to decompose and de-noise the ECG signals. To identify the significant apnea and non-apnea components from the pre-processed ECG data and to reduce the dimensionality, we used Principal Component Analysis (PCA), Kernal PCA (KPCA), and Sub-Pattern based PCA (SPPCA). These characteristics were then used to train and evaluate various machine learning models, including KNN, SVM, GaussianNB, SGD, and XGBoost, to distinguish between apnea and non-apnea ECG data. The publicly available Physionet Apnea-ECG database is used for the simulation of the proposed algorithm. To verify the performance of machine learning models, we have calculated various metrics like accuracy, precision, recall and F1 score. The validation of the proposed method is done by comparing the classification metrics with the latest state-of-the-art works.
Multipath Separation and Parameter Estimation by Single RIS Antenna in Fading Channel
Authors: Lou Yangming
Published: August 2021

Channel identification and measurement accuracywill greatly affect wireless communication performance. Thebroadcasting of electromagnetic waves will produce multipath,and its superposition will lead to fading. If the multipath canbe separated and the phase of each path can be adjustedseparately, better signal transmission and reception strategiescan be designed to weaken or eliminate fading and improvesignal transmission performance. In this paper, we first analyzethe multipath structure of the wireless channel, then utilize thedynamic isomeric characteristics of the reconfigurable intelligentsurface (RIS) antenna, also called dynamic metamaterial antenna(DMA), to form differentiated patterns, and rapidly sampleswithin a period of single pilot symbol, so that a group ofmultipath signals are projected on multiple patterns and pathscan be separated and measured. We simulated and evaluated the normalized mean square error of the parameter estimates, including angle of arrival and path gain of channels underdifferent conditions. The results demonstrate that even single1-bi coding RIS antenna can achieve well multipath separationand parameter estimation effects.
The European Union’s Budget: Focus on Own Resources Post-2020
Authors: Buzková Romana
Published: August 2021

This paper provides an overview of the European Union’s revenue system, focusing on own resources and their possible reform. It further analyses the European Commission’s proposal of the next multiannual financial framework post-2020 and its financing. The next MFF proposal introduces, in addition to the traditional resources, a basket of new own resources (based on the Common Consolidated Corporate Tax Base, the European Union Emissions Trading System and plastic packaging waste that is not recycled).
Access to File: Right(s) of the Defence or Defence of the Right(s)?
Authors: Costaș Cosmin Flavius
Published: August 2021

In November 2017, the Court of Justice of the European Union ruled in the Romanian Ispas case and decided that taxpayers are entitled to have access to file in VAT inspections. The unprecedented recognition of the fundamental right(s) of the defence leads to a number of questions as to the extent of the breach the Court made in the regular defence of national tax administrations. The paper aims to look into the lights and shadows of the European VAT inspections and to scientifically build a specific model for the appropriate exercise of taxpayers’ access to file, in particular with regard to VAT fraud cases. In this respect, the author shall consider comparative approaches and a thorough analysis of the Court’s case law concerning VAT and procedural rights. Equally important, the paper shall consider the possible effect of the Ispas judgement on the general development of the European rights of defence in all tax cases.
Ex Ante “Regulation”? The Legal Nature of the Regulatory Sandboxes or How to “Regulate” Before Regulation Even Exists
Authors: Kálmán János
Published: August 2021

Prior to the Global Financial Crisis, financial innovation was driven by so many factors, but the Global Financial Crisis changed the regulatory pendulum, which has swung to deeper regulation and also changed the way we think about financial innovation. The financial innovation – with its bright and destructive outcomes – is an integral part of the competition in the financial market. But the race is such that the regulatory authorities are in a rather disadvantaged position if we just think of the old fashioned regulatory paradigm. In this context, the question is what – new – legal institutions – such as the regulatory sandbox – could provide financial stability and a proper legal regulation to unregulated financial products and services.
The Financial System as a New Theoretical and Legislative Term
Authors: Kohajda Michael
Published: August 2021

The aim of this paper is to define the basic characteristics of the term of the financial system as a legal term. In the paper, the author finds the absence of a general or a legal definition of this term in both the Czech scientific and practical environment as essential, as this term is already used in the Czech positive law. At the same time, he briefly defines the terms of the financial markets and the capital market as terms different from the term of the financial system. This objective is fulfilled by the author with the aim of the use of the term financial system (but also the financial markets or the capital market) in a labelling of the financial law sub-branch.
Changes of Rules Applicable to Value Added Tax
Authors: Kopyściańska Katarzyna
Published: August 2021

Every year the state budget loses several dozen billions of zlotys. What provides the measure of the extent of this loss is “the tax gap” (although in fact it is not a gap) which shows the level of discrepancies between theoretical receipts due to the state budget and receipts actually collected in its fiscal function.The paper therefore explores the analysis of selected changes which have been implemented and which are commonly referred to as “the tightening of the tax system”. This is the reaction to those behaviours within legal and commercial exchanges which could be classified as a misuse of the tax system. The paper collates the most important, in the author’s opinion, possible legal responses to exchange situations having as their consequence an impairment or threat to the financial interest of the state, including, in particular, the phenomenon for which the standard term in criminal law dogma is tax loss. In the paper, possible methods of countering tax losses in the tax system will be addressed, while identifying mechanisms which are relevant for the legal construction and specificities of the tax on goods and services. The existing legal regulations are not sufficient for preventing fiscal fraud; the structure of the tax itself and the rules on setting the tax rates are the source of the threats encountered, while the expectations placed upon the valued added tax by the EU and the Member States are not met.
