Steuerrabatt für neu Zugewanderte: Was ist zu erwarten, worauf kommt es an?
Authors: Brücker Herbert , Kosyakova Yuliya , Weber Enzo
Published: September 2024

The German Government’s growth initiative aims to strengthen immigration into the labour market. In the first three years, 30 %, 20 % and 10 % of the gross income of newly arrived skilled workers will be tax-free. The target group has not yet been precisely defined, but it is likely to be workers with professional and university qualifications under the Residence Act. This Act focuses on the immigration of skilled workers, including the EU Blue Card and the regulations for IT specialists. Under certain conditions, tax rebates can trigger additional migration. However, there are also disadvantageous deadweight and distributional effects. The aim must be to avoid a race to the bottom between international tax rates.
One Zins Fits All? Die Gratwanderung der EZB
Authors: Hungerland Wolf-Fabian
Published: September 2024

This paper analyses the European Central Bank’s (ECB) challenge in applying a uniform interest rate across the economically diverse Eurozone using the Taylor Rule. The analysis reveals that the ECB’s one-size-fits-all interest rate often fails to align with the economic conditions of individual member states, leading to periods of overly restrictive or loose monetary policy, especially noticeable during significant events like the global financial and euro crisis and during the recent inflation spike. The findings suggest a significant mismatch between the ECB’s actual rates and those recommended by the Taylor Rule, with the discrepancies largely dependent on the assumed natural interest rate. The analysis reveals that varying assumptions about the natural rate significantly affect the perceived appropriateness of the ECB’s policies, and that only the inclusion of monetary policy instruments beyond the interest rate help explain these findings.
Etanercept induced erectile dysfunction
Authors: Sonmez Ozge , Ugurlu Serdal
Published: September 2024

Background:

Ankylosing spondylitis (AS) is a chronic inflammatory disease of the axial spine. Etanercept is a Tumor necrosis factor-alpha inhibitor (anti-TNF) that is widely used in the treatment of AS. The most common side effects of etanercept are infection, rash, and injection site reaction. Here, we reported an adverse event probably associated with etanercept.

Case Presentation:

A 30-year-old male patient with AS initiated etanercept due to uncontrolled back pain despite adequate doses of non-steroidal anti-inflammatory drugs. He developed erectile dysfunction (ED) within 1 month of etanercept treatment. ED disappeared after switching to secukinumab.

Conclusion:

There is limited data on the potential effects of anti-TNF on sexual function. ED might be a rare side effect of etanercept that resolves upon discontinuation of the drug. Secukinumab might be considered as an option in case of etanercept-induced ED. Even though ED is not a life-threatening side effect, switching medications could significantly improve patients’ quality of life.

PRINSIP TUNTAS SEBAGAI MANIFESTASI KEADILAN DALAM UPAYA REKONSTRUKSI PUTUSAN ATAS GUGATAN TIDAK DAPAT DITERIMA
Authors: Samsiati Samsiati
Published: September 2024

Sampai saat ini peraturan perundang-undangan yang berlaku di Indonesia belum secara jelas mengatur mengenai putusan yang amar putusannya menyatakan gugatan tidak dapat diterima (Niet-Ontvankelijk verklaard). Meskipun terdapat yurisprudensi yang mengisi kekosongan hukum tersebut, keseragaman belum dapat tercapai. Hal ini berpotensi menimbulkan Niet-Ontvankelijk verklaard bertentangan dengan asas cepat, sederhana, biaya ringan serta tuntas. Untuk menganalisis masalah ini, penelitian ini menggunakan pendekatan undang-undang, konseptual, kasus, dan komparatif. Penelitian ini melahirkan kesimpulan: Pertama, alasan hukum dari Niet-Ontvankelijk verklaard sebenarnya dimaksudkan agar gugatan perdata yang cacat formil dapat diselesaikan pada awal proses penyelesaian perkara, tanpa terlebih dahulu memeriksa pokok perkara. Kedua, sangat penting untuk memperkenalkan ketentuan baru dalam Hukum Acara Perdata Indonesia yang mengatur: jenis dan bentuk eksepsi; aturan tentang pembatasan upaya hukum terhadap Niet-Ontvankelijk verklaard; dan penegasan kewenangan hakim secara aktif dan ex officio yang menyatakan bahwa gugatan tidak dapat diterima, tanpa keberatan atau eksepsi dari tergugat, sepanjang putusan didasarkan pada alasan-alasan eksepsi.

Published: September 2024

Lipodystrophies can be generalized and partial/localized lack of subcutaneous tissue, which are uncommon heterogeneous illnesses that can be hereditary or acquired. Acquired partial lipodystrophy’ (APL) is the new name for lipodystrophia progressiva, also known as Barraquer–Simons syndrome (BSS). It could come after a severe viral infection like the measles. Young people and children both experience it. Typically, BSS or APL starts between the ages of 5 and 15. The principal feature of BSS is cephalothoracic lipodystrophy, which affects the face, neck, arms, thorax, and upper abdomen in a cephalocaudal pattern. Alternate complement pathway activation and C3 hypocomplementemia with adipocyte lysis brought on by complement 3 nephritic factor (C3NeF) have been suggested as potential causes of fat loss in individuals with APL, even though the precise process is still mostly understood. Therapeutic options for lipodystrophy include fat fillers. Different types of autologous fat transplants are possible. Autologous free fat graft where a mass of tissue harvested from any discrete subcutaneous location and implanted at a recipient site. Dermofat grafts are made from tissue that has been removed from a region, allowing for the removal of full-thickness skin grafts and the primary closure of defects. The dermofat graft can be employed as a spacer between gliding tissues or as a filler. Omental flaps, which are revascularized fat flaps, can be utilized for microvascular transfer, soft-tissue filler for hemifacial atrophy, or to cover any significant skin defects. When fat is extracted, processed, and transplanted in liquid injectable form for a variety of purposes, it is known as free fat injection.

Published: September 2024

The northern Bangka Island is composed of Pemali metamorphic complex which is indicated by the collision between Indochina and Sibumasu blocks. These features are interesting to observe because the metamorphic rocks could be recorded in some geological structures at different times. The study began by conducting field observation on Pemali Metamorphic Complex as objects. Field observation aims to collect lithological data, structural data, and oriented rock samples. The results of field pitching were processed to determine macrostructures, microstructures, and mineral distribution. The data was analyzed based on kinematic, descriptive, and deformation mechanisms to determine the deformation patterns that occurred in the study area.
Field and oriented thin section data show structures and occurred in different deformation conditions. The analysis based on macrostructures and microstructures showed that the northern part of Bangka Island experienced three different deformation phases. Deformation begins with the formation of folds that are associated with collisions between Sibumasu-Indochina, followed by a second deformation that forms a fold with different verging. Both deformations are formed in the ductile zone and the brittle-ductile transition zone. The third deformation occurs when rocks have been lifted to the surface by the presence of faults, joints, and veins. The sequence of the deformation model is similar to the deformation experienced in the Bentong-Raub suture zone formed in the shear zone.

Published: September 2024

The development of the industrial world is getting faster from time to time. The manufacturing industry is one of the industries that is very developed, especially in the use of technology. Although there have been some studies on the tensile strength of PLA filaments however, it is not yet clear about the effect of annealing treatment on the tensile strength of PLA filaments from 3D printers. Therefore, this study was conducted to determine the effect of annealing temperature on the tensile strength of polylactic acid material printed by 3D printers. This research uses experimental methods with the following conditions: The filament used is polylactic acid (PLA), specimens are printed to ISO 527-2 standard and the annealing treatment temperature are 50⁰C and 70⁰C. From the results of testing and data analysis that has been carried out, it can be concluded that annealing treatment is quite influential on the tensile strength value of polylactic acid (PLA) materials. The greater the annealing temperature, the higher the tensile strength value. At 50⁰C annealing the average tensile strength value is 15.89 MPa, while at 70⁰C annealing the average tensile strength value is 16.66 MPa.

Modeling ground motions and crustal deformation from tsunami earthquakes: Rupture parameter constraints from the 2010 Mentawai event
Authors: Nye Tara , Sahakian Valerie , Melgar Diego
Published: September 2024

We use a combination of near-field simulated and observational data to constrain the rise time, rupture velocity, and high frequency stress parameter for the 2010 M7.8 Mentawai tsunami earthquake. Tsunami earthquakes, which are shallow-rupturing events generating exceptionally large seafloor displacements, are challenging for current tsunami early warning systems. A combination of near-field high-rate GNSS and seismic data can be used for early-discrimination, but the dearth of data from these events limits testing of such an implementation in a real-time scenario. In lieu of near-field data, models with realistic rupture physics can be leveraged to improve local tsunami warning. We develop recommendations for such parameters based on observations of near-field data from the 2010 M7.8 Mentawai earthquake. We find that rise time and rupture velocity covary, and that rise time–rupture velocity combinations ranging from 5.4 s–1.23 km/s to 12 s–1.6 km/s adequately model the long duration of the Mentawai event. We find that a stress parameter of 1.43 MPa best models the high frequency deficiency. We present equations which can be used to determine reasonable parameter values for simulating tsunami earthquakes, and we find that simulated data generated with the recommended parameters capture defining characteristics of tsunami earthquakes.
Peculiarities of anisotropic ultrasonic transmission passage in deep sea water areas
Authors: Elokhin A. P. , Ulin S. E. , Shustov A. E. , Sveshnikov N. M.
Published: September 2024

It is necessary to solve the problem of transmitting to the operator the information received by the underwater dosimetric complex within the framework of the works devoted to estimations of radioactive contamination of the bottom surface of deep sea areas. The use of standard radio channel in such conditions is impossible, therefore it is expedient to use ultrasonic channel of information transmission. Thus, the issue of ultrasonic anisotropic radiation transmission in deep sea water area is considered. Anisotropy of radiation is necessary to reduce the error and increase the reliability of information transmission. A boundary value problem to estimate the ultrasound pressure on the aquatic medium is formulated and its solution in the form of a wave equation in seawater is given. Attention is paid to such characteristics of sea water areas as water salinity, liquid column pressure determining its density, temperature, range of radiation propagation taking into account its frequency characteristics. The problem is solved by the known method of separation of varia­bles in spherical geometry taking into account the anisotropy of radiation, the given characteristics of which are determined on the basis of the optimal choice of the radiation direction to the ultrasonic buffer device located on the water surface of the water area, determined experimentally. The calculation results show that at the radiation frequency of 1 kHz the detector reliably registers the signal at a distance of ~ 1 km. As the frequency increases, the signal is noticeably absorbed and at a radiation frequency of ~ 40 kHz begins to fall sharply from a distance of ~ 20 m. Similar results are obtained when the problem is solved in the form of radiation of a wide beam. The results of solving the problems allow to formulate certain requirements for the design of ultrasonic detectors used for underwater transmission of information, which will make it possible to implement the method of information transmission from deep water areas when using an underwater dosimet­ric complex and, in addition, to develop a sound method of communication in deep water areas, which will play a significant role in solving the problems of information transmission in these specific condi­tions.

Published: September 2024

The article shows the importance of additional information support for the NPP operation and emergency and crisis control centers involvement taking into account the safety of operation as the highest priority. Emergency control tools used at Russian nuclear power plants allows to obtain the nuclear power plant operational information outside the automated control system for these purposes. The main consumer of such information is the JSC Rosenergoatom Concern Crisis Center, its capabilities allow regular exercises with modeling of emergency situations at nuclear power plants and working out the actions of personnel. There have been significant changes in the operating systems market in Russia recently, a number of regulatory documents have been issued that include additional requirements from the point of view of information security to obtain data from automated control systems. Rostov NPP has been successfully operating a system of process parameter presentation for more than 20 years, it provides the operation engineering support personnel and crisis centres with all necessary information on the safety of power units in real time. Considering the Rostov NPP experience, the need to develop a new generation of means of transmitting and presenting technological information to the automated control systems of NPP power units is shown. Possible options to overcome the existing limitations are considered in the paper. It proposes a scenario of development and implementation of means of transmission and presentation of technological information at Rostov NPP, including a number of specific functions. The Rostov NPP experience in developing a new generation of means of important technology information transmission and presentation can be replicated at other Russian nuclear power plants.
Architect-engineer participation in the life cycle of nuclear power plant: tools, opportunities and prospects
Authors: Koltun O. V. , Ivanov S. O. , Yakubov D. V.
Published: September 2024

The established practice of making a decision on the construction of a new nuclear power plant occurs after the approval of the technical and economic requirements for it, taking into account the need to ensure them during the construction process. It is no secret that the most important indicators of technical and economic requirements, such as capital costs and construction time, are currently not kept for almost all nuclear power plant projects. As a rule, this indicates an insufficiently good elaboration of the project, imperfection of the estimate documentation, and management problems during construction. A distinctive feature of the construction of nuclear power plants in the Russian Federation is that the operating organisation is at the same time the customer of the project, taking part in ensuring all stages of the life cycle of the nuclear power plant, and bearing responsibility for achieving the technical and economic requirements of the project. In this regard, an urgent task is to provide expert support to the project customer from an expert organisation capable of independently assessing the quality of the project and the progress of its implementation. The necessity of support of the technical customer's activity by an expert organisation - architect-engineer is outlined on the basis of positive experience.  Taking into account the world practice of designing, building and operating engineering-complex and capital-intensive projects, it is necessary for the architect-engineer to substantiate a number of optimisation measures based on the use of modern methods (requirements management, application of technical, economic and mathematical models, development and application of digital models and digital twins of nuclear power plants). The necessity of using decision expertise in managing and quality control of nuclear power plant design and construction is substantiated using a technical and economic model and digital twins for new nuclear power plant projects at all stages of their life cycle.
Meteorological features of NPP construction regions in Nigeria
Authors: Orumo K. B. , Ksenofontov A. I. , Elokhin A. P.
Published: September 2024

The paper considers the application of meteorological characterisation methodology to the regions recommended for NPP construction in Nigeria. Regions Geregu and Itu are considered as such, with significantly different meteorological characteristics, as they are located in different parts of the country (the former in the arid region, in the centre of the country, the latter - on the coast of the Gulf of Guinea in the Niger Delta). The methodology provides the mathematical apparatus for calculating the main characteristics of the surface layer of the atmosphere model. The use of this apparatus made it possible to estimate the general character of meteorological characteristics of the regions (longitudinal wind speed, turbulent diffusion coefficient, parameter characterising the transverse dispersion of impurity) and their averaged values used further as some parameters allowing to determine the characteristics of environmental radioactive contamination, which can include the air basin and the underlying surface. The use of a geophysical model of the surface layer of the atmosphere and the meteorological parameters obtained made it possible to answer a number of questions concerning the peculiarities of atmospheric transport of radioactive impurity characteristic of the regions of Nigeria in which the Government of Nigeria intends to build nuclear power plants. Therefore, the axial and transverse distributions of radioactive impurity as a function of atmospheric stability were obtained under hypothetical radiation accidents, which revealed the peculiarities of p/a impurity distribution in these regions. The presented results of calculations should be taken into account when estimating the size of the sanitary protection zone around NPPs in one and another region and the necessary and sufficient number of environmental radiation monitoring stations when they are located within these zones

Equipment of foreign manufacturers was widely used in the Russian industry in the recent past. At the same time technical support for the operation of such complex equipment is currently significantly hampered or non-existent under the pressure of sanctions and system restrictions imposed on Russia. The Novovoronezh NPP staff is confronting successfully such challenges by developing technical solutions that enable the continued efficient operation of imported equipment under the new reality. One of the many examples of the efforts of the Novovoronezh NPP staff to ensure Russia's economic safety and technological sovereignty is given in this article. During operation of power units with VVER-1200 reactors, failures in operation of turbine unit rotor hydraulic lift pumps of Allweiler GmbH (Germany) were identified. As part of the programme of import substitution and improvement of equipment reliability on the basis of available documentation and comparative analysis of operation modes of turbine unit rotor hydraulic lift pumps pumps at Novovoronezh and Leningrad NPPs, the technology of turbine unit rotor hydraulic lift pumps repair with modernisation of internals by means of installation of bronze bushing and observance of precise clearances of pump internals is developed. Improved circuit solutions for the system of hydrostatic lifting of rotors are proposed which exclude damage to the turbine unit rotor hydraulic lift pumps during operation of the power unit at capacity and during scheduled preventive maintenance. The modernisation of equipment manufactured in Germany and its successful operation at Novovoronezh NPP is a vivid example of a scientifically sound technical response to the sanctions pressure of foreign countries and can be extended to other Russian enterprises as a positive practice.
Justification of the transition to erbium fuel in VVER-1000 type reactors based on a comparative analysis of reactivity coefficients for gadolinium and erbium burnable absorbers
Authors: Muzafarov A. R. , Savander V. I.
Published: September 2024

The paper presents the neutron-physical justification of replacement of the burn-up gadolinium absorber placed in a small number of fuel elements by erbium placed in all fuel elements of the fuel assembly. A scheme of fuel elements placement is chosen for the gadolinium absorber, modeling their real arrangement in fuel assemblies with maximum concentration of gadolinium in fuel elements (8%). In the selected scheme the center fuel element is symmetrically surrounded by two rows of fuel elements with the total number of fuel elements of 18. When selecting the weight content of erbium in fuel elements not only the total compensated reactivity reserve for the campaign is taken into account but also intrinsic safety properties such as the density and total temperature coefficients of reactivity on the fuel loading coolant which allows reducing the negative influence of erbium on the burnup of unloaded fuel. In addition, the erbium homogeneous arrangement in fuel elements leads to a uniform distribution of energy release in comparison with the gadolinium absorber. The comparative analysis of neutron-physical characteristics of the reactor is carried out for the considered absorbers on unit cells and polycells taking into account simplified burnup models at partial reloads without fuel assemblies rearrangements. Repetitive structures consisting of 3 fuel assemblies with different irradiation durations are formed under the condition of application of threefold partial fuel reloading in the core. The obtained results clearly demonstrate that the reactivity coefficients for the erbium absorber have higher values than for the gadolinium variant under the condition of equal compensation of excess reactivity. Taking this factor into account, it is possible to select such a weight content of erbium in fuel elements when losses in burnup will be insignificant.

The purpose of this study is to assess the needs of students and teachers for improving speaking abilities and to validate the usage of interactive video in the classroom. The ADDIE model's research and development (R&D) methodology was employed in this study: analysis, design, development, implementation, and assessment. As a result, it validated the teacher's material requirements while also analyzing the students' demands. Three English teachers and 18 secondary school students from MTS Miftahul Ulum Lumajang participated in this study. Data for this study were gathered through class observation, interviews, and questionnaires. An interview, however, revealed that the teacher frequently experienced difficulties developing English material for the junior high school class, notably for the eighth grade, due to students' questions and opinions. A questionnaire survey found that the majority of teachers (66.7%) had trouble improving pupils' speaking abilities by asking and providing opinions. According to this survey's findings, most students (72.2%) struggle to improve their speaking skills through questioning and replying. As a result, interactive video must be used. This study has given the majority of teachers a favorable impression of the efficiency of interactive movies in improving speaking proficiency.

Making mathematical models involves translating real-life situations into mathematical expressions. This research, conducted in three Bandung schools with 93 students, focuses on iconic and symbolic mathematical models. Findings reveal that students' abilities using these models are below the expected minimum, with symbolic models being more dominant. The score difference may be influenced by the teacher's role, students' experiences, individual abilities, and specific contexts favoring visual understanding. Students face challenges in making mathematical models, including a lack of comprehensive understanding, difficulty identifying variables, creating context-free models, and struggling with relevant visualizations. Additionally, they encounter issues using formulas and interpreting mathematical results when answering questions. In the validation stage, adjusting temporary results to real situations poses challenges. Internal factors contributing to difficulties include a lack of interest, critical limitations, and low self-confidence. External factors like a limited practical experience in making models also play a role. A holistic solution addressing both internal and external factors is essential for students to overcome challenges and enhance their ability to create mathematical models from real-world contexts. The recommended role of the productive struggle learning approach is crucial in assisting students in achieving the expected milestones.
