Cyborgs on the horizon. Are we ready? Examining the (a)legality of transhumanist practices within the EU
Authors: Martínez-Ramil Pablo , Bolaños-Frasquet Haridian , Solarte-Vasquez Maria Claudia
Published: April 2023

Summary

Most western contemporary legal systems are grounded in natural law principles established by modern humanism even though various alternatives, post-humanism being among the most influential, start influencing their understanding. In addition, the effect of the rapid pace of technological development on humanity has made the inherent limitations of its rules and other social arrangements manifest, as the use of technology is growingly used for human enhancement. The advocacy seeking to expand the catalogue of human rights and to cover transhumanism has started to bear fruit, but more conceptual developments are needed to lay the foundations for a more systemic regulatory development. This reflection paper focuses on the use of microchip implants, from among the augmentation practices that have recently flown under the radar of legal scientific research. These electronic devices re-shape the experience of being human and their various applications suggest that the penetration levels of capacity enhancing technologies will continue to be on the rise. It will discuss and clarify whether and to which extent transhumanism, personal rights and private autonomy are connected, and the former sufficiently covered by the right to bodily integrity (RBI). The reflection will rely on a comparative and interpretative approach based on the extant literature, national and European Union (EU) regulatory initiatives, and recent doctrinal developments found in case law.
Ostalgy in Flux? Transformations of the concept reflected in the case of (East) Germany
Authors: Körfer Petr
Published: April 2023

The contribution focuses on the origin, genesis and transformation of (n)ostalgy in the new German Bundesländer. It focuses on the political-ideological, life biography, societal and economic frame of ostalgy and presents this phaenomenon as a general East-Central European feature. Later, it specifically analyses the East German case presenting and analysing the uniqueness of this case. The intra-German discourse is used as the main shape for such analysis, and the bipolarisation of the discourse and the stereotypes used. In the last analytical part we present the transmission of ostalgic supporters of the successor Party of Democratic Socialism towards the new radical party Alternative for Germany, showing the overlap of ostalgy as the socio-economic and ideo-political background with the new forms of anti-liberal and nativist stances.
Hardening Accelerators (X-Seed 100 BASF, PCC, LKD and SALT) as Strength-Enhancing Admixture Solutions for Soil Stabilization
Authors: Lindh Per , Lemenkova Polina
Published: April 2023

This study is aimed at evaluating the strength of stabilised soil collected from the Port of Norvik, Stockholm, Sweden, where 350,000 m3 of clay had to be stabilized. The tests were performed in the laboratory of the Swedish Geotechnical Institute (SGI). The soil was stabilised by binder mixtures using Portland cement clinker (PCC) and lime and lime kiln dust (LKD). Accelerators (X-seed 100 BASF, PCC, LKD and salt) were added to the soil samples for quicker stabilization. The strength of the stabilised soil was assessed using resonance frequency measurements of seismic P-waves by an ICP accelerometer in order to estimate the shear strength of the soil and to evaluate the effects from the accelerators, binder ratios, and the curing temperature on the gains in stabilization and strength. Various proportions of the binders were tested, i.e.: 50/50 cement/lime and 50/50 PCC/lime. The temperature was measured using a calorimeter in double experiments. The results showed that the accelerators improve the strength in the stabilized specimens and enhance the soil performance for engineering construction work.
The Impact of Climate Change and Regulation of the Water Regime on the Morphological Structure of the Floodplain Forests in Petržalka, Slovakia
Authors: Gáspár Viktória , Škrinár Andrej
Published: April 2023

The main landscape-forming component has always been the forests in the lowlands. The devastation and disturbance of forest areas by anthropogenic activity change the ecological conditions in their environment. Climate and atmospheric changes affect the balance of the mutual relationships between individual components, as well as the existence of direct and feedback relationships in forest ecosystems. The transformation of bioclimatic and ecological conditions have caused the degradation of the Pannonian floodplain forest communities in Slovakia. Urbanization in Bratislava has caused the fragmentation of the surrounding forests. With changes in sunlight and heat conditions, flood-plain communities are forced to become acclimatized to drier conditions, which lead to morphological and structural changes in their composition.

In this study we examined phytocenological records from 1999 to 2020 from various sources. The survey points to the impact of climate change and anthropogenic influences on biodiversity. The absence of floods and the drying of floodplain forest soils could have caused this change in the species' composition.

Published: April 2023

The lithium-ion battery context can be implemented in learning by using green chemistry in analyzing students' scientific literacy. This study aims to investigate the scientific literacy profile of students who appear in lithium-ion battery learning with a problem-based learning model in high school. The scientific literacy indicator is used based on the 2015 PISA Framework. The method used in this research is descriptive qualitative. This research was conducted in one of the high schools in the city of Bogor, West Java. The research subjects consisted of 27 students of class XII MIPA 6. The instruments used were observation, LKPD, and audio-video during the learning process. The data obtained were analyzed using Transcript-Based Lesson Analysis (TBLA). The results showed that the 4 indicators of scientific literacy appeared in the learning of the first meeting and the second meeting. The results show that the profile of the emergence of scientific literacy of students at the first meeting is an indicator of scientific knowledge (39%); indicators of science competence (38%); context indicators (13%); and science attitude indicators (10%). The profile of the emergence of scientific literacy of students at the second meeting, namely the knowledge indicator (37%); competency indicators (31%); context indicator (25%); and science attitude indicators (7%). The overall results show that the 4 indicators of scientific literacy that appear are related to each other, but are still low. The low achievement of students' scientific literacy is because they are not used to expressing what is in their minds and teachers have not been able to ask questions that encourage them to be scientifically literate. Analysis of scientific literacy activities and dialogue during learning can be used as a reflection for teachers to evaluate and improve further learning.
Evaluation of the hepatoprotective role of ethanolic Saussurea lappa root extract in female rats experimentally exposed to propylthiouracil
Authors: Mohamed Rashed Abd  , Saleh M Rahim  , Ahmad Hamed Saleh
Published: April 2023

Propylthiouracil (PTU) is often used to produce experimental hypothyroidism. In general, PTU generates hepatotoxicity, albeit with dissimilar incidence rates of hepatotoxicity. This study examined the hepatoprotective effects of Saussurea lappa root ethanol extract on experimentally induced hepatotoxicity in female rats. For this study, 25 adult female albino rats were placed into five equal groups: control, PTU, post treated with S. lappa extract, co-administered PTU with S. lappa extract 300mg/kg, and post-treated with levothyroxine. Serum gamma-glutamyl transferase (GGT) activity, total protein, thyroid hormones (T3, T4, and TSH), and oxidative stress parameters (catalase, superoxide dismutase, reduced glutathione, and lipid peroxidation levels) were measured. The liver tissue underwent histological examination. Current findings revealed that S.lappa ethanol root extract significantly improved hepatotoxicity as evidenced by reversal of various biochemical and histopathological changes in female rats. Current study has shown that this promising impact may be due to the antioxidant and free radical scavenging characteristics of S.lappa constituents.

Authors: AKTUĞ Zait Burak , İBİŞ Serkan , PİŞKİN Necdet Eray , YAVUZ Gönül , KUTLU Zeynep
Published: April 2023

The purpose of this study is to compare the effects of using different masks on respiratory parameters such as maximum oxygen consumption (VO2max), oxygen saturation (SpO2), and running distance. Twenty men aged 18-22 who exercised regularly four days a week participated in the study. The participants VO2max values with the astrand test, respiratory parameters with the spirometer, SpO2 with the oximeter, and running distances with the 20m shuttle run test were determined three times on different days, without mask, with the surgical mask and with the N95 mask. In repeated measurements, Friedman Test was used to determine the difference between the measurements. After the exercises, it was determined that the VO2max values, respiratory parameters, and SpO2 measurements without mask were statistically significantly higher than the measurements with N95 masks. It was also determined that the running distance decreased after the use of surgical masks and N95 masks while N95 masks caused a higher decrease. Masks should not be used in exercises performed outdoors and in places with little contact, gymnasium, etc. In closed areas, it may be recommended to use surgical masks. Considering the changes in all the parameters measured, it is not appropriate to exercise with N95 masks.

Background: A set of environmental preventive measures involving ventilation control within healthcare facilities is well established. Portable air purifiers have been introduced in recent years as one of alternative technologies used to prevent infection and other respiratory complications in indoor environment. Objective: To asses indoor air quality in pediatric intensive care units at two tertiary hospitals in Riyadh, Saudi Arabia in the presence and absence of portable air purifiers.Method: Fine particles (PM 2.5) and coarse particles (PM10) were obtained using optical particle counter and microbial counts were obtained using Andersen air sampler from outdoor and two patient rooms in pediatric intensive care units. Pollutants levels reduction between outdoor and indoor were calculated and compared using Statistical Package for the Social Sciences software (SPSS Version 27.0. Armonk, NY: IBM Corp) were utilized for statistical analysis. Results: In hospital A and B, non-protective environment room (NPE) had a significantly higher number of fine particles and total bacterial count (TBC) respectively than semi-protective environment room (SPE). Meanwhile, there was significantly higher reductions of fine particles (hospital A) and coarse particles, fine particles and TBC (hospital B) in SPE rooms compared with NPE room. Hospital-A had significantly higher reduction efficacy compared with matched rooms in hospital-B for fine particles, coarse particles, and TBC. Conclusion: This study demonstrated that portable air purifiers have a great impact in the reduction of indoor air pollutants in PICUs including fine particulate matters and TBC in particular. Furthermore, ventilation systems equipped with HEPA filters along with portable air purifiers significantly reduce the levels indoor air pollutants of outdoor sources. Moreover, this study showed that newer and well-maintained HVAC systems play a significant role in controlling the levels of airborne pollutants.
Energy efficiency of conventional air conditioning systems in light of climate change
Authors: Ghaith Fawaz Khaled
Published: April 2023

The energy used in a country's economy is very important to its development. Over the years, the electricity and ventilation consumption of buildings have increased. People's concerns about the quality of their indoor environment are also increasing. Most buildings have air conditioning and ventilation systems that are designed to provide an environment that’s comfortable and healthy for the occupants. This is done through the use of ventilation. In addition to improving the indoor air quality, it can also help prevent people from experiencing discomfort. Studies have shown that about 60% of office buildings' energy consumption is attributed to the use of air conditioning systems. These systems provide cool air to the spaces while keeping the temperature controlled. A VAV system can meet the health criterion and the IAQ by supplying enough fresh air to meet national standards. A conventional AC system requires a refrigeration plant and a network of pipes to deliver cold water to the spaces. Since air-cooled chiller systems have a flexible design, they are commonly used in commercial buildings. They can provide a cooling effect that's significantly higher than that of water-cooled units. Compared to water cooling systems, air-cooled units are more energy-efficient. This is because the head pressure control of the system ensures that the pressure is kept high. The use of air conditioning has been one of the biggest sources of electrical energy consumption worldwide. It has contributed over 10% of the total energy produced, and it contributes to the harmful effects of climate change. Climate change is a growing concern that will require the production and use of more air conditioning units. This has necessitated the development of a comprehensive research to address this issue.

The modern Russian criminal market of services permitted in civil circulation: characterization and determination
Authors:   Irkutsk State University, Repetskaya A. L. ,   Baikal State University
Published: April 2023

Presents a modern (2017-2022) characteristic of the Russian criminal market of services permitted in civil circulation, but performed without a license or special permission, i.e. in the shadow sphere. The traditional segments of the specified market (household services, financial, cleaning, advertising services, etc.), as well as types of services whose development is associated with the pandemic that occurred during the study period (medical, funeral services) are considered. A comparative analysis of the state of these segments of the studied market at the beginning and end of the study period is carried out. The dominant determinants contributing to the development of various segments are analyzed. Among the main factors determining the identified changes are: restrictions associated with the spread of the COVID-19 pandemic; the pandemic itself, which influenced the change of many relationships in public life, including economic ones. The author comes to the conclusion that global digitalization, which undoubtedly influences the mechanisms of provision and payment of the services in question, is not of fundamental importance for the development of the main part of the segments of the criminal market in question, however, there are types of markets that have changed significantly due to the development of Internet technologies (advertising services). The impact of the emergence, receipt and use of cryptocurrencies is analyzed separately. Based on the data obtained, the author’s forecast of the development of the studied market segments for the near future is proposed.
Church and state in New Zealand, 1930-1935: a study of the social thought and influence of the Christian Church in a period of economic crisis
Authors:   , Reid Anthony
Published: April 2023

The origin of this thesis was a purely theoretical problem - that of the meeting of the ideal and the possible, the ethical and the political. Is it possible to speak of a 'Christian' approach to politics and economics, and if so can it expect to be influential? Since setting off on this note I have been led along unexpected paths, and what has emerged could hardly claim to answer, or perhaps even ask, the original question. The period was narrowed to the depression since it marked a stage when fundamental political ideas were nearer the surface than usual. The subject gradually restricted itself to the Church, and became increasingly concerned with the nature of the Christian ethic rather  than its influence. The final product must stand as a detailed study of the interaction of Church and society at a time of particular social and  economic stress. As political history it can be no more than an essay in public opinion; as religious history it may be an excessively ambitious exploration of an important but neglected field - the Church's responsibility to society.
