Cross-Border Loss Relief in the European Union Following W AG (Case C-538/20)
Authors: Kostikidis S. , Striefler F.
Published: April 2024

In W AG (Case C-538/20), the ECJ ruled that denying relief for final treaty-exempted losses of foreign permanent establishments (PEs) does not run afoul of the freedom of establishment. This article shows that a denial of relief for such losses should not be based on the incomparability of domestic and foreign treaty-exempted PEs, however, it can be justified on the basis of what the authors call a “symmetrical exercise of taxing powers”. Finally, the authors provide some predictions, assuming the ECJ continues its W AG line of jurisprudence.
The Digital Public Square meets the Digital Baton

The value a society and its laws place on protecting free speech is arguably most keenly felt where that speech takes a critical turn. Which is why the history of this field is littered with prosecutions and penalties being levied against problematic speech, inviting courts to draw the lines between what is protected and what is not. The past ten years in India demonstrate that when faced with speech that is critical of government policy or state action, the state has become increasingly hesitant to let it remain on air. What is perhaps most alarming for the health of democracy is that, in most cases, there is often a synergy across the three arms of the State that curbing problematic speech is the best course of action to follow.
Staatliche Schutzpflichten gegen Rassismus statt AfD-Verbot
Authors: Barskanmaz Cengiz
Published: April 2024

Der Rassismus- und Antisemitismusvorwurf dient als wesentliches Argument für ein Verbot der AfD. Aus rassismuskritischer Perspektive geht die Verbotsdebatte allerdings fehl. Sie erschöpft sich in einem symbolischen Antirassismus, der eine ebenso symbolische Antirassismuspolitik fördert, die an der Realität vulnerabler Gruppen vorbeigeht. Zudem externalisiert die Debatte um das AfD-Verbot den Rassismus der sogenannten Mitte und wirbt für einen rechtsstaatlich und demokratietheoretisch bedenklichen repressiven Antirassismus.

The average annual temperature of 9.2 °C with a deviation of +0.9 °C above the 1991–2020 normal (and +1.7 °C from the 1961–1990 normal) classifies the year as a temperature normal year. The annual precipitation amount of 630 mm classifies the year as normal compared to both the 1961–1990 and 1991–2020 normals. The highest and lowest temperatures, significant precipitation events and, where applicable, higher wind speeds and snowfall, and groundwater statistics are shown for each month. If the level of flood activity in Czechia was reached, it is also listed in the overview. With respect to the air quality, cases exceeding the limit values for human health protection, and smog situations declared are listed. Compared to the 10-year average (2012–2021) the dispersion conditions were significantly better in 2022. Good dispersion conditions, as expressed by the ventilation index for the whole country, were recorded in 320 days (88%), moderately poor dispersion conditions in 42 days (11%) and poor dispersion conditions in three days (1%) in 2022.

Although the IUCN Red List Categories and Criteria is a widely internationally used system for classifying species at high risk of extinction, the micro-organisms are still practically excluded from the appropriately enlisted taxa. The present paper provides a method, which gives means to assess microalgae threat status much more objectively than it was possible before and in this way to achieve quite high degree of generalization in work with this peculiar group of organisms. The method described below uses the widely accepted standard IUCN Red List system of categories, but proposes their assignment on the basis of a complex application of seven criteria relevant to microalgae and classical data, available for them. These criteria can be interpreted in the same way for all taxonomic groups of algae and for all possible territorial levels (local, national, regional, global). The criteria are denominated with Latin capital letters A-G and each of them has a numerical expression with values (points) ranging between 4 and 1. The final assessment of the threat status is done on the basis of the total amount of points (T), which ranges between 7 and 28. In this way each alga is supplied with a formula (a combination of letters and numbers), which indicates its threat status and in the same time outlines its most critical, “weak spots” on which special attention has to be paid when conservation measures have to be proposed. As it is exemplifi ed in detail in the paper, the formula could be expressed in a table or in a text format, in full or in a short version, depending on the needs of the relevant studies or proposals (e.g. Anabaena lapponica Borge [VU – A3 B4 C4 D2 E2 F2 G3], or Anabaena lapponica Borge [VU – A3 B4 C4 D2 E2 F2 G3 T20], or Anabaena lapponica Borge [VU – T20]), or Anabaena lapponica Borge [VU]).

Nuclear Energy for Net Zero: Accelerating Investment in Clean Energy Transitions
Authors:   INTERNATIONAL ATOMIC ENERGY AGENCY
Published: April 2024

Written to inform the international energy and climate change community in the context of the G20 under the Presidency of Brazil, this publication provides an overview of the contribution of nuclear energy to global climate change mitigation pathways toward net zero, highlighting the investment requisites. Global mitigation scenario pathways disseminated by the Intergovernmental Panel on Climate Change (IPCC) and the International Energy Agency (IEA) indicate significantly more nuclear electricity – a doubling or more by 2050 – as a key part of the solution to limit global warming to the 1.5 and 2 degree goals of the Paris Agreement. Nuclear heat and hydrogen can also play a role in decarbonizing hard-to-abate activities in heavy industry and transportation. Unlocking and accelerating investment would be necessary for the rapid deployment of nuclear energy, including in emerging markets and developing economies. This calls for consistent climate, energy and investment policy frameworks — embracing a wide array of financing approaches — in tandem with efficient markets, effective project risk management and multi-stakeholder cooperation to accelerate annual nuclear energy investment to reach net zero. This publication presents key information and data to support and advise decision makers.

Authors: Ye Shengke , Dai Kaiye , Fan Guoli , Zhang Ling , Liang Zhihao
Published: April 2024

In this study, the network security of PostgreSQL database using Socket connection is deeply analyzed. By exploring Socket connections established by PostgreSQL over TCP, we find potential security threats and vulnerabilities during data transmission, which may expose database systems to network attacks such as unauthorized access and data leakage. In order to assess these security risks, this study simulated a variety of network attack scenarios, especially the implantation and detection of Webshell, to reveal the vulnerability of PostgreSQL to such network threats. Especially in defending against complex and changeable cyber threats such as Webshell attacks, this research also uses machine learning and artificial intelligence techniques to improve the automation level of security threat detection and response. These technologies can help identify complex attack patterns and improve resilience to emerging threats, thereby enhancing the overall security of PostgreSQL databases.

Sikh-Period Architectural Ornament in Punjab: A Synthesis of Tradition & Innovation
Authors: Khan Nadhra Shahbaz
Published: April 2024

Architecture commissioned by the Lahore Darbār during the first half of the nineteenth century is generally dismissed as imitative and derivative of earlier practices by colonial and later historians. This article introduces three salient features of Sikh-period architectural ornament: repoussé work, carved-brickwork and ornamental brackets, that highlight the aesthetic culture they were produced and received in, challenging this unfounded censure. A study of creative use of each technique on selected buildings in Lahore and Amritsar offers evidence of carefully planned embellishment programs that were not only original but were also meaningful as they effectively convey the spirit of the buildings they adorn.

Sipora Island in the Mentawai Islands Regency is prone to land movement disasters that can damage and cause losses to the people who live on Sipora Island, plus very little data base related to land movement maps on the island. To reduce the risk that will arise, it is necessary to map land movement using the PS-InSAR method, using 48 scenes of Sentinel-1A images and comparing the amplitude stability index parameters 0.65, 0.75, and 0.85 to get differences in the distribution of land movement points and the number of land movement points on the island of Sipora, to see the relationship between the value of the amplitude of the stability index is done fisher test, amplitude stability index parameters 0.65 and 0.75 can map points with subsidence value up to -99mm / year while the amplitude stability index parameter 0.85 can map points with subsidence value -87mm / year all parameters have a maximum uplift value of 5mm / year. The number of points obtained with an amplitude stability index of 0.65 is 27561, 0.75 is 961 and 0.85 is 255. The distribution of land movement points parameter value amplitude stability index 0.65 covers the entire surface of the island of Sipora, the distribution of land movement points amplitude stability index 0.75 focuses on the north and south of the island and the distribution of land movement points amplitude stability index 0.85 in the northern part of the island. The difference parameters of amplitude stability index 0.65, 0.75 and 0.85.

Continuous monitoring of solar panel performance is essential to ensure effective and efficient generation of electrical energy. Developing a monitoring system such as an I-V characteristic curve tracker enables real-time monitoring and identification of potential problems or efficiency improvements. The system utilizes a circuit switching system for accurate and continuous measurement, providing insight into how the solar panel responds to changing environmental and load conditions. The data recorded by temperature, light intensity, current, and voltage sensors on the solar panel provides valuable information about its condition and the environmental factors affecting it. Utilizing IoT technology allows real-time monitoring of the data, accessible via a web page and presented graphically. The data is also stored in Excel format for further analysis, so users can access and monitor continuously as long as they are connected to the internet. From the experimental results, the Voc of the solar panel ranged from 18.7 V to 20.42 V, and Isc between 0.0727 A to 0.2145 A, which were tested under solar irradiation ranging from 100 to 500 W/m². This research demonstrates the importance of continuous monitoring and the effectiveness of the developed monitoring system in providing real-time data for analysis and optimization of solar panel performance. The system has been tested to meet the IEC No. 13B-23 standard for accuracy classes 0.2 and 0.5. A comparison between manual testing and sensor testing shows that despite the difference in accuracy levels, the sensor measurements have a relatively low average error (1.04% for voltage and 0.64% for current) compared to manual measurements, indicating that the sensor is reliable in providing accurate data. This demonstrates the reliability and effectiveness of using the sensor in the solar panel characteristics monitoring system.

The management of aggressive strains of Phytophthora infestans is a challenge for Mexico, so the objective of study proposed to validate and monitor the efficacy of (Oxatiapiprolin), against the sensitivity of P. infestans micropopulations, isolated from the field. A modified protocol with leaf discs and five concentrations of the fungicide at a pressure of 1.2 bar was tested against a severe late blight isolate from the Toluca Valley, State of Mexico. The fungicide showed an inhibitory effect on a mixed isolate of P. infestans under in vitro conditions, compared to the first five concentrations used in the test (1-0.0016 ppm). It was observed that at a higher concentration, there was an increase in the sensitivity of the pathogen and less damage to the tissue. After 5th concentration, less than 25% of tissue was affected (0–2.6 mm) compared with the damage in control (13 mm) (>95%), when the fungicide was not applied. The mean inhibition (EC50) is high calculated at approximately 0.00034 mgL-1 of the fungicide, which inhibits 50% of the growth of the pathogen.

Estimados lectores:La pandemia que ataca al mundo, la globalización, los cambios medioambientales y la crisis económica están causando transformaciones sociales que provocan el aumento de las desigualdades. Estos cambios hacen necesarias soluciones emergentes e innovadoras que respeten valores universales como la paz, la dignidad humana, la igualdad de género, la no violencia y la no discriminación. Los actores principales de las transformaciones sociales son los jóvenes, que se ven más afectados por estos cambios. Es por ello que las transformaciones sociales que se llevan en los contextos deben lograr inclusión e innovación social, con especial atención en los vulnerables, desfavorecidos y excluidos.En tal sentido, la UNESCO aplica el Programa de Gestión de las Transformaciones Sociales para llevar a cabo iniciativas que establecen vínculos entre los conocimientos en ciencias sociales, las políticas públicas y la sociedad para asegurar su implementación. Desde la participación social se debe lograr entonces la democratización de las instituciones y la sociedad para construir la ciudadanía. Este último número de la Revista Metropolitana de Ciencias Aplicadas presenta algunos ejemplos de formas emergentes de transformación que se han llevado a cabo en diferentes contextos sociales con vistas a mitigar los daños de la pandemia COVID-19 en el planeta, pues estudios científicos han demostrado que la destrucción de los ecosistemas han generado un desbalance biológico que ha influenciado en la transferencia de este tipo de virus y bacterias hacia la especie humana.Es nuestro mayor deseo que las contribuciones que se realizan les sirvan de base para estudios relacionados con su área de investigación

Attention deficit and hyperactivity disorder (ADHD) is one of the disorders that children present with great frequency in Early Childhood Education. This negatively influences the care process of these infants. Teachers of Initial Education are not always prepared to give adequate psycho-pedagogical treatment to these children during the teaching-learning process. It is important to know the manifestations of this entity to be able to give the appropriate pedagogical response and to ensure that infants maintain their attention towards teaching activities. On the other hand, painting is considered as a manifestation of artistic expression in Initial Education, which constitutes an important area of learning, therefore, it is known as one of the activities that contributes, due to its characteristics, to achieving the attention and motivation of children with ADHD during the learning process corresponding to their level. The objective of this work is to offer a series of teaching activities based on painting, for this study population between 3 to 4 years old, in order for them to maintain their attention and motivation from the creative process they carry out as result of the activity of painting.

An important characteristic of cancer is aberrant metabolism. Drug resistance, cancer stem cells, metastasis and tumorigenesis are all significantly impacted by abnormal cancer metabolism, which includes enhanced anabolic pathways and aerobic glycolysis. The Hippo pathway, Myc and PI3K/AKT are recognized oncogenic signaling networks that control the expression of metabolic genes and increase the level of activity of metabolic enzymes. On the other hand, abnormal metabolic pathways result in disruptions to the internal signal transduction pathways of cells, providing energy, building blocks and redox capabilities necessary for uncontrolled cancer cell proliferation. Studies and clinical trials are being carried out to investigate the impact of minute substances or dietary modifications, such as calorie restriction, fasting and intermittent fasting, on the inhibition of metabolic enzymes. The metabolic phenotypes of malignancies are remarkably diverse, much like genetic variability. Genetic abnormalities and a variety of signals found in the tumor microenvironment contribute to this variability. Therefore, one of the main objectives of contemporary cancer therapies is to overcome metabolic plasticity. This overview explains the relationships between biochemical and pathways of signaling and emphasizes recent research on the metabolic properties of cancer. We also present fresh justifications for the upcoming class of medications that target cancer metabolism. This is an overview of our latest studies on the progress of nanomedicine and disease detection at the tiny level of nano-bio interactions between biological systems and nanoparticles. Significant progress in the field of nanomedicine has been accomplished in the last 20 years. However, the absence of a thorough knowledge of nano-bio interactions in the clinical situation makes it difficult to significantly improve overall patient survival with nanomedicine.
