Additive manufacturing technologies such as laser powder bed fusion (LPBF) provide unprecedented abilities to manufacture complex 3-D parts and structures; however, the process produces leftover metal powder that is often unused, resulting in significant cost and disposal overhead. Towards this end, to ensure the ability to recycle the unused powder that is typically found within the build volume and in the overflow compartments of LPBF systems, a thorough chemical and structural analysis is required. Such an analysis will help in determining the extent of recyclability and reusability of the unused powder. For these purposes, characterization of recycled powder for Inconel 718 was performed in this work as a function of build-cycle to compare and contrast the evolution in physical and chemical properties such as particle size distribution, morphology, and composition. We note that the analysis was carried out for 21 build-cycles. Characterization of the particle size distribution and circularity was performed using traditional scanning electron microscopy methods and that information was later compared to measurements of surface profile using coherent scanning interferometry. Reusability was assessed using these results in conjunction with chemical analysis of the powder that was carried out using energy dispersive X-ray spectroscopy. For the extent of build-cycles considered in this work, it was seen that the physical and chemical changes in the recycled powder were will within accepted limits for powder usage and that with appropriate measures, recycled powder can be re-incorporated for subsequent builds without compromise in the powder quality. This study provides a pathway for greatly reducing powder consumption and thus cost during the LPBF process.
Numerical modelling of a deep closed-loop geothermal system: evaluating the Eavor-Loop
Authors: Kelly Joseph J. , McDermott Christopher I.
Published: February 2022

Conventional geothermal energy systems are limited by hydrogeological conditions and environmental risks, and wind/solar solutions have issues with intermittency and the need for grid storage. Deep closed-loop geothermal systems such as the Eavor-Loop are championed as scalable, dispatchable, zero-emission alternative energy technologies, but as yet they are largely untested. A series of numerical models are created using the finite element method to evaluate the power output claims made by Eavor. The models use typical parameter values to create a simplified study domain. The modelling results show that the power output claims are plausible, although the upper range of their predictions would likely require production temperatures in excess of 150 ℃. The technology is shown to be scalable by adding additional lateral wellbore arrays, but this leads to a reduction in efficiency due to thermal interference. It is demonstrated that the presence of groundwater can improve power output at relatively high hydraulic conductivity values. Doubt is cast on the likelihood of finding such values in the deep subsurface. Flow rate is shown to increase power output, but the practicality of using it to follow energy demand is not established. Various limitations of the study are discussed, and suggestions are made for future work which could fill in the remaining knowledge gaps.
Stochastic two-scale convergence and Young measures
Authors: Heida Martin , Neukamm Stefan , Varga Mario
Published: February 2022

In this paper we compare the notion of stochastic two-scale convergence in the mean (by Bourgeat, Mikelić and Wright), the notion of stochastic unfolding (recently introduced by the authors), and the quenched notion of stochastic two-scale convergence (by Zhikov and Pyatnitskii). In particular, we introduce stochastic two-scale Young measures as a tool to compare mean and quenched limits. Moreover, we discuss two examples, which can be naturally analyzed via stochastic unfolding, but which cannot be treated via quenched stochastic two-scale convergence.

Niz kamnitih gomil na severnem kraškem robu je C. Marchesetti v začetku 20. stoletja razložil kot bronastodobne grobne gomile. S. Gabrovec jih je vključil v kaštelirsko kulturo srednje bronaste dobe in jih primerjal s podobnimi is- trskimi grobnimi gomilami. Zaščitna izkopavanja gomile na Ostrem vrhu so l. 1992 razkrila ovalno zgradbo premera 11 m, grajeno v suhozidni tehniki. Obodni zid je bil širok med 1,5 in 2,5 m, v višino pa je bil ohranjen do 1,9 m. V zidu so se ohranile zunanje in notranje niše za nosilne lesene tramove, kar kaže na leseno nadgradnjo kamnite zgradbe, verjetno stolpa. Jama za nosilni tram v osrednjem delu stolpa dokazuje, da je bil tudi nadstrešen. Niz radiokarbonskih datacij kaže na mlajšehalštatsko starost izgradnje in uporabe stolpa. Verjetno je bila vzdolž severnega kraškega roba zgrajena vrsta stolpov, ki so bili skupaj z nizom manjših, močno utrjenih gradišč namenjeni nadzoru dostopa in obrambi ozemlja centralnih gradišč kraške kulturne skupine med 6. in 4. st. pr. n. št.
Le discours des Sciences Sociales sur l’Arctique. Analyse lexicale des résumés de l’ICASS
Authors: Vaguet Yvette , Jeanne Philippe
Published: February 2022

Les hautes latitudes demeurent globalement peu visitées par le grand public. Pourtant, elles font l’objet de représentations sociales largement partagées (l’image d’une "course aux ressources", d’une faune et flore polaire sous la menace du réchauffement climatique, etc.). Ces représentations sont co-construites dans un processus où les médias et les scientifiques jouent un rôle significatif. Les résumés des présentations scientifiques lors des International Congress of Arctic Social Sciences (ICASS) constituent un matériau de première main jamais analysé. Leur exploration par analyse textuelle conduite avec le logiciel ALCESTE montre clairement les thèmes privilégiés par les SHS et les réseaux de chercheurs en Arctique, à l’instar de la qualité de vie à mettre en regard du jeune réseau sur la Santé et le bien-être en Arctique. Elle montre également une sous-représentation de la Russie parmi les participants, avec des conséquences très nettes : sous-représentation des terrains arctiques russes et des recherches sur la ville polaire. L’analyse des dernières éditions d’ICASS révèle une partition binaire modernité-tradition systématique qui invite à interroger la dimension normative des dispositifs de mesure.
On Cost-Aware Heterogeneous Cloudlet Deployment for Mobile Edge Computing
Authors: Ye Hengzhou , Huang Fengyi , Hao Wei
Published: February 2022

Edge computing undertakes downlink cloud services and uplink terminal computing tasks, data interaction latency and network transmission cost are thus significantly reduced. Although a lot of research has been conducted in mobile edge computing (MEC), which assumed that all homogeneous cloudlets are placed in WMAN and user mobility is also ignored, little attention is paid to how to place heterogeneous cloudlets in wireless metropolitan area network (WMAN) to minimize the deployment cost of cloudlets. Meanwhile, the method of selecting an optimal access point (AP) for deployment, modeling and heuristic algorithm (HA) needs to be improved. Therefore, this paper design a new heterogeneous cloudlet deployment model considering the quality of service (QoS) and mobility of users, and the Improved Heuristic Algorithm (IHA) is proposed to minimize cloudlet deployment cost. The extensive simulations demonstrate that IHA is more efficient than HA and the designed model is superior to the existing work.

Published: February 2022

Biometric recognition may be used in conjunction with human authentication on a smartphone to improve accuracy, reliability, and simplicity, and to aid in fraud prevention and user authentication. While single biometric authentication addresses environmental degradation and sensor noise limitations, and the single point of failure scenario in biometric systems can result in more robust biometric systems, multimodal biometric authentication can improve the accuracy of identification and recognition. The purpose of this research is to propose a facial and speech authentication system that is cloud-based and supports a web-based examination approach. The system enables students' biometrics to be registered, students to be recognized, and student recognition results to be reported. The confusion matrix is used to compare the results of positive and negative detection in various ways, including accuracy score, precision value, and recall value. Adaptive multimodal biometric authentication should be designed and evaluated for further research using the optimal weights for each biometric.

Published: February 2022

Overview: Laparoscopic myomectomy has become increasingly popular in Sri Lanka due to its favorable long term outcome. Purpose of this study is to evaluate not only laparoscopic myomectomy technique but also operative time, blood loss depending on site, size and number of fibroid. Method: In this retrospective study we have analyzed data from 432 women who had undergone laparoscopic myomectomy at Colombo South Teaching Hospital, Sri Lanka during the period from 2011 January to 2021 January. Data were collected from patient database, hospital records and histopathology data base. Data were collected according to demographical details including age, BMI, parity and past surgical histories, myoma details including size, type, site and number, intraoperative details and postoperative data. Results: Mean age of patients undergone laparoscopic myomectomy are 35.5 years (SD 6.083) Majority of the population (67%) were nulliparous. Indication wise 192 patients (44.4%) had pressure symptoms,137 patients (31.7%) presented with heavy menstrual bleeding and 103 patients (23.8%) had subfertility history. Regarding fibroids characteristics, single fibroid found in 168 patients (38.9%), fibroids between 2-4 found in 199 patients (46.1%) and fibroids 5-10 found in 65 patients (15%). Considering the location of fibroid, 192 patients (44.4%) had anterior wall, posterior wall in 125 (28.9%), fundal in 87 (20.1%), broad ligament in 21 (4.1%) and other locations in 7 patients (1.6%). Regard to type of the fibroids intramural fibroids identified in 196 patients (45.4%), sub serosal in 136 (31.5%), submucosal in 75 (17.4%) and pedunculated in 22 patients (5.1%). Mean blood loss was 159.4 +/- 68.03 ml while mean operative time was 124 +/- 49.6 minutes. But those differs with number and size and site of the fibroids. Mean blood loss and operative time increased when fibroids number and size increased. Mean operative time is 92.23 minute for fibroid size less than 8cm vs 178.9 minute for fibroid more than 12cm. Mean blood loss is 115.25ml for fibroid less than 8cm vs 238.27ml for fibroid size more than 12cm. Mean operative time for single fibroid is 90.8 minute vs 179.5 minute for fibroids 5-10. Mean operative time and blood loss are increased with posterior wall and broad ligament fibroids. However, it is not statistically significant (P Value 0.006 and 0.008 respectively). Prolonged operative time did not impact on surgical outcomes in terms of hospital stay and blood transfusion. Conclusion: In experienced and expert hand, laparoscopic myomectomy is a safe procedure with good surgical outcomes and low complication rate. Operative time and blood loss are mainly associated with the size of largest fibroid and number of fibroids. Open myomectomy may be of benefit for number of fibroids > 10 when considering completeness of surgery. Hand morcellation through suprapubic port is a safe and effective method of specimen retrieval in laparoscopic myomectomy.

Published: February 2022

Background: The current conventional drug susceptibility test (DST) for Mycobacterium tuberculosis (Mtb) takes several weeks of incubation to obtain results. As a rapid method, molecular DST requires only a few days to get the results but does not fully cover the phenotypic resistance. A new rapid method based on the ability of viable Mtb bacilli to hydrolyze fluorescein diacetate to free fluorescein with detection of fluorescent mycobacteria by flow cytometric analysis, was recently developed.Methods: To evaluate this cytometric method, we tested 39 clinical isolates which were susceptible or resistant to isoniazid (INH) or rifampin (RIF), or ethambutol (EMB) by phenotypic or molecular DST methods and compared the results.Results: The susceptibility was determined by measuring the viability rate of Mtb and all the isolates which were tested with INH, RIF, and EMB showed susceptibility results concordant with those by the phenotypic solid and liquid media methods. The isolates having no mutations in the molecular DST but resistance in the conventional phenotypic DST were also resistant in this cytometric method. These results suggest that the flow cytometric DST method is faster than conventional agar phenotypic DST and may complement the results of molecular DST.Conclusion: In conclusion, the cytometric method could provide quick and more accurate information that would help clinicians to choose more effective drugs.

NF-erythroid 2–related factor 2 (Nrf2) is a major transcription factor to protect cells against reactive oxygen species (ROS) and reactive toxicants. Meanwhile, Nrf2 can inhibit contact dermatitis through redox-dependent and -independent pathways. However, the underlying mechanisms of how Nrf2 mediates irritant contact dermatitis (ICD) are still unclear. In this article, we elucidated the role of Nrf2 in 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced acute ICD. Our study demonstrated that the ear thickness, redness, swelling, and neutrophil infiltration were significantly increased, accompanied by increased expression of inflammatory cytokines (IL-1α, IL-1β, IL-6, etc.) and decreased expression of antioxidant genes (HO-1 and NQO1) in Nrf2 knockout mice. Moreover, ERK phosphorylation was elevated in mouse embryonic fibroblasts (MEFs) from Nrf2 knockout mouse. Inhibition of ERK significantly alleviated TPA-induced cutaneous inflammation and ROS accumulation in MEFs derived from mouse. Conversely, ROS scavenging inhibited the ERK activation and TPA-induced inflammation in MEFs. Taken together, the findings illustrate the key role of the Nrf2/ROS/ERK signaling pathway in TPA-induced acute ICD.

Published: February 2022

Customer loyalty has gained great consideration in recent years. It is crucial for hotel’s success and survival in this competitive market. This research intends to determine the factors contributing to customer loyalty in budget hotel sector in Egypt. This research was investigated by adopting a quantitative research approach. A structured survey was set up involving 33 items to measure customer loyalty and investigated constructs. The outcomes of this study highlighted low level of customer loyalty in budget hotels in Egypt. Four determinants were identified to have major positive impact on customer loyalty respectively: corporate image, price perception, physical environment and switching costs whereas CSR did not have significant effect on customer loyalty. The research implies that budget hotels’ managers should invest in improving the factors that were identified as influential/supportive to attract and retain customers. They should deal with customer loyalty as a strategic target and maintain a long-term relationship with customers to enhance their repurchasing intentions. This research contributes to boost customer loyalty in the context of budget hotel sector. It provides a range of tools and recommendations that will motivate customers’ re-buying behavior and make them more emotionally-tied to small hospitality organizations.

A Research Study and Comparative Analysis of MPPT Controllers for PV Cells with Algorithmatic Structures
Authors: Jasvir Singh, Puneet Chopra and Simerpreet Singh
Published: February 2022

Due to continues increase in usage of various sources of Energies, Solar energy becomes very popular
source of renewable energy due to its several advantages. Systems such as Photovoltaic (PV) power systems
have been widely used in many applications of generation and utilization of energy in many countries. But
also, there are many urgent problems to cop up with the applications of PV Cells for the purpose of Power
Generation and in the power systems such as low efficiency, high cost etc. The main Concentration is to how
to improve efficiency. Since generally Photovoltaic (PV) arrays exhibit a nonlinear power–voltage (P–V)
characteristic curve which have a variation with isolation and temperature. To achieve good efficiency,
Maximum Power Point Tracking (MPPT) is a very important technology. There are various conventional MPPT
schemes have been proposed and working on including Hill-Climbing (HC) , Perturb and Observe (P&O) , and
Incremental Conductance (INC) etc. In this research work, the optimization methods for efficient tracking
such as PSO and GSA are explored. The very essential and considered issue of this type of control (MPPT) is
to how to achieve the best optimized status and this can be achieved by using evolutionary algorithms. PSO
algorithm owns the characteristics methods like parallel processing, good robustness, and high probability of
finding global optimal solution. By adding GSA with PSO ,it can be improved. Advantage of adding proposed
GSAPSO algorithm greatly shortens the searching time, helpful in reducing the fluctuation of output waveform
and thus improves the optimization and efficiency through particles dormancy and activation control, optimal
number of particles algorithm and search sequence selection. It achieves a smooth starting for maximum
power and achieves it in less time than the widely used other methods.

Sob uma abordagem quanti-qualitativa, de caráter bibliográfico e inventariante, construir um estado da arte sobre a Ginástica Para Todos (GPT) em periódicos nacionais é o foco deste estudo. Assumindo o recorte temporal entre 1979 e 2020, 21 periódicos foram investigados dos quais 69 publicações sobre GPT foram identificadas em 16 deles. O contexto não escolar se exalta (34), seguido do escolar (23) e 12 trabalhos que se referem a ambos os contextos. Há prevalência de estudos empíricos (47) em relação aos bibliográficos e/ou documentais (22). Destaca-se a abordagem qualitativa de pesquisa que indica uma perspectiva mais interpretativa e subjetiva ao se pensar a GPT como objeto de estudo. A região sudeste é destacada na amostra tanto quanto às localidades onde foram realizadas as pesquisas, como em relação às instituições que são vinculadas. A GPT é confirmada como expressão gímnica integrativa e abrangente, aspecto verificado na diversidade de faixas geracionais e gêneros envolvidos, como sujeitos colaboradores, ressaltando, entretanto, o gênero feminino como prevalente, inclusive nas autorias dos estudos. Por fim, referenciais dos anos de 1990 e início dos anos 2000 são fortemente utilizados, confirmando a atualidade dessas produções e sua importância para nortear as discussões sobre GPT na atualidade.

Fault Identification, Classification, and Location on Transmission Lines Using Combined Machine Learning Methods
Authors: Bon Nguyen Nhan , Dai Le Van
Published: February 2022

This study develops a hybrid method to identify, classify, and locate electrical faults on transmission lines based on Machine Learning (ML) methods. Firstly, Wavelet Transform (WT) technique is applied to extract features from the current or voltage signals. The extracted signals are decomposed into eleven coefficients. These coefficients are calculated to the energy level, and the data of teen fault types are converted to the RGB image. Secondly, GoogLeNet model is applied to classify the fault, and Convolutional Neural Network (CNN) method is proposed to locate the fault. The proposed method is tested on the four-bus power system with the 220 kV transmission line via time-domain simulation using Matlab software. The conditions of the fault resistance random values and the pre-fault load changes are considered. The simulation results show that the proposed method has high accuracy and fast processing time, and is a useful tool for analyzing the system stability in the field of electricity.
Evaluation of Activation Energy for Agricultural Residues with Ignition Temperature
Authors: Lin Jeng-Liang
Published: February 2022

The objective of this study is to evaluate the activation energy of agricultural residues with their ignition characteristics. The ignition temperature of agricultural residues (peanut shell, rice hull, and rice straw) is determined by measuring particle temperature, particle luminosity, and gas temperature for samples weighing 2.0, 2.5, and 3.0 grams. The maximal slope of the particle temperature versus furnace temperature is used to determine the occurrence of ignition. Values of activation energy are analyzed by the Semenov model with the measured ignition temperature. Results show that the particle ignition temperature is 317, 324, and 330°C for rice straw, peanut shell, and rice hull, respectively. The results also indicate that the particle ignition temperature reduces as the volatile content increases and the sample amount decreases. The value of activation energy is 157.2, 170.3, and 192.8 kJ/mole for rice straw, peanut shell, and rice hull, respectively.
modelo social de discapacidad: un cambio de paradigma y la reforma del artículo 49 CE
Authors: Turturro Pérez de los Cobos Sara
Published: February 2022

En la primera parte del artículo se analiza cómo ha evolucionado la idea de discapacidad a lo largo de la historia. Más adelante, se analiza cómo se ha aplicado el actual modelo social de discapacidad a nivel internacional, europeo y nacional. La Convención de la Naciones Unidas sobre los Derechos de las Personas con Discapacidad es especialmente importante en este ámbito. Una de las mayores novedades que introduce la Convención es la idea de accesibilidad universal que, unida al concepto de “ajustes razonables”, está adquiriendo una gran importancia en la protección de las personas con discapacidad. El concepto de “ajustes razonables” ya ha sido aplicado por el Tribunal Europeo de Derechos Humanos, por el Comité Europeo de Derechos Sociales y por nuestro Tribunal Constitucional. En la última parte del artículo se analiza la posibilidad de reformar el artículo 49 de la Constitución para eliminar el desafortunado término “disminuidos” y adaptar su contenido al actual modelo social de discapacidad. La reforma del artículo 49 de la Constitución es oportuna y necesaria, pero debe hacerse de la forma debida y contando con el mayor consenso posible. Sin embargo, el Anteproyecto de reforma del artículo 49 presentado por el Consejo de Ministros, el 11 de mayo de 2021 -y que actualmente se encuentra bajo tramitación parlamentaria-, sufre importantes deficiencias técnicas y de contenido. Además, la falta de consenso amenaza su aprobación.

capitán del buque como trabajador de dirección: con especial énfasis en el derecho venezolano
Authors: Vázquez Vázquez Erister
Published: February 2022

La identificación de un capitán como empleado de dirección es una labor que corre usualmente a cargo de la doctrina y la jurisprudencia, la ley escrita rara vez se toma la molestia de aclararlo. La legislación venezolana no identifica de modo expreso al capitán con el empleado de dirección, sin embargo, la jurisprudencia ha tratado varios casos y ha adelantado interesantes motivaciones y conclusiones. Aunque a primera vista su inclusión dentro de la categoría de empleado de dirección parece ser una conclusión obvia, la aplicación de la primacía de la realidad y las variaciones de la jurisprudencia al tratar de precisar los contornos del empleado de dirección aportan elementos de incertidumbre que dan la oportunidad de analizarlo.

Published: February 2022

Esta contribución examina, en primer lugar, la situación laboral y sindical española en los últimos años del régimen franquista a la luz de la OIT. En este sentido, contiene un breve recordatorio de las estructuras sociales y sindicales presentes en España entre 1936 y 1975. En esta parte, no se trata tanto de rememorar las críticas a la situación existente durante la Dictadura como de subrayar los antecedentes de la dinámica iniciada, con la colaboración de la Organización de Ginebra, en el sistema de relaciones laborales a partir de 1975, así como la rápida creación de un sistema social democrático.

A continuación, se analizan las reformas de mayor calado instituidas tras el cambio de régimen. Para ello, se describen los logros ejemplares del país en los años inmediatamente siguientes. Se concluye extrayendo algunas lecciones de una transición particularmente corta y exitosa que pueden resultar útiles para otros países que se encuentren en el paso de un régimen totalitario a un democrático, a partir de la reflexión del papel de las instituciones nacionales en la interpretación e implementación de los convenios internacionales sobre los derechos fundamentales.

Published: February 2022

İnsanlar dünyayı kavramlar ile algılar ve anlamlandırır. Sosyal bilgiler dersi kavram açısından oldukça zengin bir derstir. Sosyal bilgiler dersi tarih, coğrafya, arkeoloji, hukuk, iletişim, felsefe, psikoloji gibi pek çok bilimin kavramlarını içinde barındırır. Öğrencilerin dünyayı anlama ve anlamlandırmasında bu kavramları etkili şekilde öğrenmeleri önemlidir. Bu çalışmanın amacı sosyal bilgiler 5, 6 ve 7. Sınıf ders kitaplarını kavram haritası çeşitleri açısından incelemektir. Çalışmada nitel araştırma yöntemlerinden doküman analizi kullanılmıştır. Doküman analizi yöntemi ile elde edilen veriler, içerik analizi ile çözümlenmiştir. Araştırma sonucunda 5, 6 ve 7. Sınıf sosyal bilgiler ders kitaplarının kavram haritaları açısından eksik olduğu, kavram haritaları çeşitlerinden sadece ünite sonunda zihin haritasının kullanıldığı tespit edilmiştir.

Kavram haritalarının kavram öğretiminde ve olayları olguları somutlaştırmada etkisi olduğundan daha fazladır. Farklı kavram haritası çeşitlerinin ders kitaplarında kullanılmasının kavram kalıcılığı artırmada ve kavramların aralarındaki ilişkileri tespit etme ve çözümleme açısından etkili bir yöntem olacağını düşünülmektedir.
Using Principles of Theatrical Intimacy to Shape Consent-based Spaces for Minors
Authors: Shively Kim
Published: February 2022

In lieu of an abstract, here is an excerpt: 

Understanding the way that the adolescent mind may respond to perceived danger and how that response could potentially become a habitualized response encouraged me to research how to adapt the best practices of boundaries and consent for specific developmental stages among minors.

As I realized the importance of adapting these best practices, I knew that this work would revolutionize middle school and high school theatre and drama programs. However, in order for these best practices to have an ultimately positive and developmentally supportive outcome, I recognized the need to make adjustments based upon the cognitive development of the artists in question. The needs of a minor in a creative environment differ from those of the adult. Through research and experimentation, I began to alter the approaches to the best practices based on the developmental stage of the subject. While the foundations remained the same, the approach and terminology shifted.  As we began to work with secondary educators at our workshops, it became apparent that bringing the best practices of Theatrical Intimacy Education to middle and high school educators was an effective next step.

The objective of this study was to compare the effect of early or late breeding on milk production in high producing dairy cows. In this aim, the cows with previous average peak milk yield above 45 kg/d (n = 48) were divided into two groups; Group1 (early bred) included the cows (n = 21) were inseminated between 45 to 75 days in milk (DIM) and Group2 (n = 27; late bred) were inseminated between 76 to 124 DIM. The cows that became pregnant at their first insemination following first estrus selected for the study. Milk yield was recorded every 5 days after calving for the first 45 days then continued for every 15 days for every each cow. Average DIM in early and late bred cows at insemination were 66 (min, 45; max, 75) and 99 (min, 76; max, 124), respectively. Average milk yield up to 271 d was similar between groups, however, average milk yield from 227 to 271 d was lower (P < 0.04) in early bred cows with 26.7 kg/d compare to late bred cows with 30.3 kg/d. Even, there was no relationship between average milk yield up to 271 d, peak milk yield and day of insemination, it may be concluded that milk yield continues with more pronounced stability through the end of lactation in late bred high yielding cows.
Responsibility of the data controllers in data protection law and the practice of the authorities in imposing administrative fine
Authors: Čerticky Mário
Published: February 2022

The European Union’s general data protection regulation ensures a high level of protection of personal data. The data controllers, during their data processing practice, must take into account not only the provisions of the Regulation but also national regulations and evolving data protection practice. Regulatory fragmentation makes it more difficult to comply with data processing standards. The responsibility of the data controller can arise in several directions, first of all, we can separate civil and public liability. The subject of this study is the examination of administrative liability within the scope of the latter, in the framework of which it analyses the theoretical and practical issues of imposing a data protection fine. For the practice of imposing fines, the decisions taken by each European Data Protection Supervisor are presented and conclusions are drawn from them.

The functional concept of a corporate responsibilty in European antitrust law, which is independent of a company’s legal form, is increasingly gaining acceptance not only at the European level but also at the national level; it allows corporate sanctioning in line with the economic and socio-political role of companies in today’s world.
Verantwortung von unternehmen im umweltschutzrecht
Authors: Csák Csilla
Published: February 2022

We can talk about environmental responsibility in several dimensions. It can be seen that legal liability is only part of the question of responsibility. Legal liability, together with the rules set out in the general codes and sui generis provisions of environmental law, also represents a complex system of administrative, civil and criminal liability. Every company reacts differently to environmental responsibility, so we can ask the question: can we talk about corporate responsibility or irresponsibility?

Does Brexit Mean Brexit? The Enforcement of Intra-EU Investment Awards in the Post-Brexit Era
Authors: Gáspár-Szilágyi Szilárd
Published: February 2022

This article uses an analytical approach in order to dissect the major legal issues concerning the enforcement of intra-EU awards post-Brexit. The outcomes of the enforcement cases will depend on the country where enforcement is sought (EU Member States, the UK, and other third countries), the applicable legal regime pursuant to which enforcement is sought (the New York Convention or the ICSID Convention), various temporal factors (whether certain key moments in the arbitral proceedings occurred before or after the end of the Brexit transition period), and whether the intra-EU cases are based on intra-EU BITs or the ECT, or both. Due to this complexity, there is no easy answer as to how the various issues arising from the post-Brexit enforcement of intra-EU awards should be solved. This is most unfortunate as it creates uncertainty for investors, host States, and national courts of enforcement alike.
