Published: April 2023

The composition of voltage-gated Ca2+channel (Cav) subtypes that gate action potential (AP)-evoked release changes during the development of mammalian CNS synapses. Cav2.2 and Cav2.3 lose their function in gating-evoked release during postnatal synapse maturation. In mature boutons, Cav2.1 currents provide the almost exclusive trigger for evoked release, and Cav2.3 currents are required for the induction of presynaptic long-term potentiation. However, the functional significance of Cav2.2 remained elusive in mature boutons, although they remain present at active zones and continue contributing significantly to presynaptic Ca2+influx. Here, we addressed the functional significance of Cav2.2 and Cav2.3 at mature parallel-fiber (PF) to Purkinje neuron synapses of mice of either sex. These synapses are known to exhibit the corresponding developmental Cavsubtype changes in gating release. We addressed two hypotheses, namely that Cav2.2 and Cav2.3 are involved in triggering spontaneous glutamate release and that they are engaged in vesicle recruitment during repetitive evoked release. We found that spontaneous miniature release is Ca2+dependent. However, experiments with Cavsubtype-specific blockers excluded the spontaneous opening of Cavs as the Ca2+source for spontaneous glutamate release. Thus, neither Cav2.2 nor Cav2.3 controls spontaneous release from PF boutons. Furthermore, vesicle recruitment during brief bursts of APs was also independent of Ca2+influx through Cav2.2 and Cav2.3. However, Cav2.2, but not Cav2.3, currents significantly boosted vesicle recruitment during sustained high-frequency synaptic transmission. Thus, in mature PF boutons Cav2.2 channels are specifically required to sustain synaptic transmission during prolonged neuronal activity.

SIGNIFICANCE STATEMENTAt young CNS synapses, action potential-evoked release is gated via three subtypes of voltage-gated Ca2+channels: Cav2.1, Cav2.2, and Cav2.3. During postnatal maturation, Cav2.2 and Cav2.3 lose their function in gating evoked release, such that at mature synapses Cav2.1 provides the almost exclusive source for triggering evoked release. Cav2.3 currents are required for the induction of presynaptic long-term potentiation. However, the function of the still abundant Cav2.2 in mature boutons remained largely elusive. Here, we studied mature cerebellar parallel-fiber synapses and found that Cav2.2 does not control spontaneous release. However, Ca2+influx through Cav2.2 significantly boosted vesicle recruitment during trains of action potentials. Thus, Cav2.2 in mature parallel-fiber boutons participate in sustaining synaptic transmission during prolonged activity.
Laboratorio curatorial feminista
Authors: Antivilo Julia
Published: April 2023

This Dialogues takes the 2017–18 exhibition Radical Women: Latin American Art, 1960–1985 as a starting point to discuss Latin American art today, addressing its history, legacy, and contribution to positive social change through the prism of feminism. Seeking to challenge hegemonic readings of the categories of “Latin America” and “feminism” while reinstating the contribution of Latin American women, Latina/Latinx, and Chicana/Chicanx artists to art and critical thought today, the exhibition Radical Women proposed novel ways of displaying art from the region by embracing multiplicity, attending to the particularity of different contexts, and bringing to the fore common threads of critical and creative practice. Building on that premise, these contributions expand on the original exhibition’s time frame and consider the persistence of feminism and its changing status in Latin American art after 1985. They explore recent artistic practices, curatorial projects, and art historical scholarship; reflect on strategies of display, audience engagement, societal concerns, and epistemological premises; and consider different ways of conceptualizing Latin American and feminist identities, legacies, and genealogies today. By doing so, this Dialogues seeks to enrich and diversify our understanding of past and current practices, as well as highlight the intricate connections and resonances that exist between the two. Contributions by curators (Fajardo-Hill, Rjeille), scholars (Fernández, Lamoni), and artists (Antivilo, Motta) span issues in political activism, ecology, technology, education, genealogy, colonization, heritage, and memory. What emerges is a sense of the field’s present concerns and the ways this is shaping the future direction of feminism in Latin American art and art history.
METHOD TO DEVELOP LATENT FINGERPRINTS ON HARD AND SMOOTH SURFACES IMPREGNATED WITH DIRT
Authors: Pacheco Edson Jorge , Antunes Antônio Azoubel , Campello Reginaldo Inojosa Carneiro
Published: April 2023

Forensic science has developed significantly over time in search of better results. Therefore, several techniques for lifting latent fingerprints at crime scenes were elaborated using developing agents, both physical and chemical. One of the most common types of surface encountered in such situations is hard and smooth surfaces, such as glass and metal. This note seeks to demonstrate the most appropriate technique for lifting fingerprints from hard and smooth surfaces that are impregnated with dirt, as the standard techniques (the use of cyanoacrylate and fingerprint powder for revealing prints) are impossible due to not being able to reach the excreted substances or destroying the prints. After applying the technique, satisfactory results were achieved that allowed fingerprint comparison tests to be carried out (highlighted by results shown in photographs), representing an easy and practical solution that enables the satisfactory development of fingerprints, greatly important to the evolution of the scientific techniques applied.
O papel da Biologia Forense na resolução de crimes de grande repercussão no Brasil e no mundo: uma revisão
Authors: De Jesus Santos Ana Claudia , Montenegro A.K.A.
Published: April 2023

A Biologia Forense é uma área da Biologia que dá suporte ao Direito, especialmente, à área criminal. A referida é composta por subáreas, tais como: entomologia, botânica, genética, hematologia forense, dentre outras. O biólogo forense é um investigador científico, que busca, coleta e analisa indícios ou vestígios biológicos relativos ao crime, em pessoas vivas, cadáveres e nos locais onde aquele ocorreu. No Brasil, assim como em outras partes do mundo, há um grande número de crimes que chocam a sociedade pelo perfil dos envolvidos, pela crueldade dos fatos e pelo inesperado, causando muitas vezes, comoção pública. Assim, objetivou-se avaliar o papel da Biologia Forense na resolução de crimes de grande repercussão nacional e mundial, afim de ressaltar a sua importância nos referidos processos, promovendo ganhos para a sociedade. Alguns dos casos de destaques abordados no presente estudo foram, “o agricultor” (1° caso documentado de Entomologia Forense), “o Bebê de Lindbergh” e o da advogada Mércia Nakashima”, todos cometidos de forma inesperada e violenta, e sempre havendo vestígios biológicos, pois tanto o assassino, quanto a vítima são compostos por estes, ou seja, não existe crime perfeito; mesmo que o local seja modificado ou o corpo transferido, como o ocorrido em alguns exemplos mencionados.  Assim, é muito importante que os estudos e as técnicas científicas evoluam constantemente, a fim de que nenhum caso fique sem solução, pois toda família tem o direito de saber o que aconteceu com o seu ente querido e que o criminoso pague perante a lei por seus crimes.

Historically, the alcohol consumption has been associated to occurrence of different crimes, including homicides, rapes and sexual assault, among others. Hence, the aim of this study was to evaluate the blood alcohol levels (BAC) in samples taken from medico- legal cases in Manaus, northern Brazil. An observational retrospective study covering May-2018 through April-2019 was carried out and the database of the referral center was employed. In total, 142 cases were evaluated. The mean age of participants was 36.2 ± 10.9 years (range 18-78 years, CI 95% 34.34-38.42) and the majority of them was male (87.32%), single (66.20%), attended the secondary school level (47.89%) and living in the city of Manaus at the time of the incidence (61.70%). The mean BAC was 0.20 ± 0.08 g/dL (range 0.1-0.64 g/dL, CI 95% 0.10-0.15). In relation to the incident, the weekday with most cases was Sunday (30.28%) and in the early morning (24 to 06 hours; 40.14%). Only a small percent was alive before the blood draw (7.04%) and traffic accidents were the most registered occurrence (61.27%). Cocaine was also found in some cases (4.23%). Highest BAC levels were observed for the homicide cases whereas lowest BAC values were attained for the suicide cases (p=0.01). Furthermore, there was a weak positive correlation between age and BAC (r=0.27; p=0.01). For the first time, the study of BAC in samples taken from medico-legal cases was performed in Manaus. Taking into account the results, authorities may develop dedicated strategies to deal with this problem.
Epigenética em Ciências Forenses

Published: April 2023

A epigenética envolve mudanças na função dos genes que não estão relacionadas a mudanças na sequência do DNA. Dentro dos mecanismos epigenéticos estão a metilação do DNA e os RNAs não codificantes (ncRNAs). A metilação do DNA é um processo pelo qual se agrega grupos metil ao DNA e geralmente tem por função, dificultar a transcrição genética. Padrões de metilação podem ser usados no campo forense para determinação tecidual e de fluidos, estimativa de idade e diferenciação entre gêmeos monozigóticos. Os ncRNAs reguladores são moléculas de RNA que não são traduzidas em proteína, e têm uma importante função na regulação da expressão gênica. Dentre eles, os mais estudados são os microRNAs (miRNAs), que podem induzir silenciamento genético através da sua associação direta com o RNA mensageiro (mRNA). Numerosos estudos publicados relatam que muitos miRNAs são expressos de maneira tecido-específica, sendo bastante promissores para o campo forense na identificação de fluidos biológicos como sangue, sêmen, saliva e secreções vaginais. Os RNAs longos não codificantes (lncRNAs) se valem de diversos mecanismos para regular a expressão gênica. Diversos estudos têm demonstrado o potencial uso dos lncRNAs como marcadores biológicos, no entanto, devido ao grande número de lncRNAs existentes, ainda precisam ser mais bem caracterizados para avaliar o seu possível uso no campo forense. As aplicações epigenéticas nas ciências forenses são relativamente novas e atualmente limitadas, entretanto, o mundo da epigenética tem o potencial de melhorar as investigações criminais, aumentando a quantidade de informações que podem ser obtidas de materiais biológicos obtidos nas cenas de crimes, contribuindo assim, no que diz respeito as evidências criminais para o sistema judicial.
The effects of Some Organic Compounds on Yield and Fruit Quality in Albion Strawberry (Fragaria x ananassa Duch) Cultivar
Authors: Cankurt Kasım , İpek Muzaffer
Published: April 2023

Strawberry is one of the most popular fruits in Türkiye, and its cultivation is increasing due to its high adaptability to different climatic and soil conditions. Greenhouses and conventional agriculture are preferred in strawberry cultivation in terms of both growing conditions and the applicability of good agriculture and organic agriculture. Good agriculture and organic agriculture have increased their importance in achieving reliable and quality food, according to the World Health Organization (WHO). For these reasons, the application compounds are increasing day by day. Accordingly, the types and varieties of organic compounds have increased. Albion strawberry cultivars were grown under calcareous soil conditions, and the effects of various organic component levels on yield and fruit quality were examined. In the experiment, vinasse, molasses, and vermicompost (liquid) were each employed at quantities of 2.5%, 5%, 7%, and 10%. Because of the treatments, a vinasse concentration of 2.5 % was shown to be more beneficial than the others on yield metrics such as yield per decare (1664.89 kg) and yield per plant (332.98 g) (332.98 g). There was a marked improvement in fruit quality between the molasses treatments and the other organic compound treatments. It was discovered that the treatment with molasses at a concentration of 2.5 % (15.94 %) had a greater TSS than the other treatments, whereas the treatment with molasses at a concentration of 5.0 % had to have a higher TAC of 1.058 %. Based on the results, strawberry farmers can be told that using vinas and molasses together is an effective way to increase strawberry yield and improve the quality of the fruit.

Coriolopsis trogii and Cerrena unicolor were investigated for laccase production in submerged fermentation with different nutrient medium containing metal ions and lignocellulosic materials. The maximum laccase activity of C. trogii Han751 was 8584.44 ± 98.45 U/L and was obtained from nutrient medium 7. However, the maximum laccase activity of C. unicolor Han 849 was 16144.26 ± 635.30 U/L from nutrient medium 9. Thus, the capacity of secreting laccase of C. unicolor Han 849 was superior to that of C. trogii Han751. Different fungal species have different medium components suitable for laccase production. The content of CuSO4·5H2O and MnSO4 in nutrient medium with the concentration of 0.25 g/L and 0.151 g/L, respectively, was more beneficial to C. trogii Han751 secreting laccase. However, the vital components of nutrient medium that contribute to the laccase activity of C. unicolor Han 849 were corncob, glucose, and CuSO4·5H2O, with the corresponding concentrations of 1 g/flask, 5 g/L, and 0.25 g/L, respectively. The results will contribute to the development of new methods to produce low-cost laccase.

This paper is devoted to the important problem of creating a method for predicting the intensity of erosion-corrosion destruction of the working blades material of low-pressure stages of powerful steam turbines, considering the complex physical processes that accompany the emergence, transformation of erosion-hazardous droplets and their interaction with elements of the flow path. The features of the construction of some existing erosion models are considered. The model that is developed at the Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine and based on a deterministic-statistical approach to its creation is analyzed in detail. The calculations performed during the research showed a satisfactory coincidence with the results of experimental tests by various authors, obtained on droplet impact stands, which contributed to the successful use of the model in creating a comprehensive method of predicting the wear of working blades. To do this, it was supplemented by the method of determining the parameters of the erosive environment based on the droplet movement equation, taking into account the size distribution law. Along with that, it is shown that the considered model, although it allows to carry out fairly accurate prediction of the development of erosive wear at the modern level, has difficulties in its construction due to the need to identify it from the data of full-scale experiments, the number of which is limited. It has been established that one of the important reasons for the discrepancies that arise is the failure to include of the electrophysical component of the processes occurring in a two-phase flow. In this regard, the results of comprehensive studies of steam electrization and its influence on the working processes of wet steam turbines are considered. It is shown that the change in the properties of the working medium as a functional erosive medium as a result of electrification causes a significant increase (relative to neutral wet steam) of electrochemical processes. At the same time, the kinetics of the damage accumulation to the metal surface layer changes due to the joint occurrence of several negative processes: droplet impact influence; electrochemical processes caused by mechanical and structural and chemical heterogeneity of the surface; hydrogen absorption; changes in mechanical properties under the electric field influence. It was noted that the contribution of hydrogen absorption to changes in mechanical properties is the greatest. According to a preliminary assessment, the complex negative droplet impact and electrophysical influence on the metal surface reduces the incubation period and intensifies the erosion-corrosion process by approximately 2 times

Global decarbonisation and widespread use of alternative and renewable energy sources aims to shortage the fossil fuel using and reduce the harmful impact on the environment within the framework of the sustainable development paradigm. At the same time, wide integration into the power network of unmanaged generating units based on renewable energy sources in the absence of a sufficient number of electric energy storage units of the required capacity in conditions of unpredictability and instability of production may lead to the inability to provide reliable coverage of the consumers power load, which requires the use of alternative ways of balancing the power system. Under such conditions, the coordination of electric power (electricity) demand and supply for should be carried out exclusively by demand-side management in real time or near real time. That is why the improvement of methodological and instrumental provision of demand-side management tasks today is one of the most important components of the effectiveness of the "green" transition. To achieve the goal, the article analyzed the existing DSM-methods, performed an analysis of the requirements of national regulatory documents for DSM and service provision in the liberalized electricity market of Ukraine, described an improved ideal norm method and a modernized toolkit for demand-side management, as well as a reliable budgetary technical solution for the formation of information support for DSM in the retail electricity market is proposed, which together with dynamic pricing and the introduction of real-time tariffs will contribute to ensuring economic regimes of operation of the IPS and high-quality power supply to consumers.

Methods of Brain Extraction from Magnetic Resonance Images of Human Head: A Review
Authors: Praveenkumar S. , Kalaiselvi T. , Somasundaram Karuppanagounder
Published: April 2023

Medical images are providing vital information to aid physicians in diagnosing a disease afflicting the organ of a human body. Magnetic resonance imaging is an important imaging modality in capturing the soft tissues of the brain. Segmenting and extracting the brain is essential in studying the structure and pathological condition of brain. There are several methods that are developed for this purpose. Researchers in brain extraction or segmentation need to know the current status of the work that have been done. Such an information is also important for improving the existing method to get more accurate results or to reduce the complexity of the algorithm. In this paper we review the classical methods and convolutional neural network–based deep learning brain extraction methods.
Experiencing Intrusion: Smashed Windows as Violations of Privacy in the University Town of Helmstedt, 1684–1706
Authors: Ljungberg Johannes , Körner Natalie P.
Published: April 2023

This article argues that much of what we refer to as privacy in present-day society was materialised, experienced, instrumentalised, and also, to some extent, protected before the 19th century, when it was broadly conceptualised as a value and a right. In a social-architectural approach, windows and facades of the private house are shown to have had an important regulatory function, mediating between the house and the neighbourhood, the open and the closed, and the public and the private. First ,we extract evidence from On the Art of Building in Ten Books by Leon Battista Alberti (1404– 1572) as well as from other architectural treatises of the period and region, in particular those by Joseph Furttenbach (1591–1667) and Leonhard Christoph Sturm (1669–1719), who cites Nicolaus Goldmann (1611–1665). Then, we combine the architectural insights with an in-depth reading of two well-documented but not yet analysed court cases of nocturnal window smashing in the university town of Helmstedt involving Professor Johann Barthold Niemeyer (1644–1708) in the opposing roles of both victim and instigator. The combination of these court cases and architectural treatises allows us to show how experiences of intrusions via broken windows share qualities with today’s conceptualisation of intrusions of privacy and thus point to the presence of notions of privacy in early modern societies.

The European Union as an Actor Navigating International Regime Complexes
Authors: Delreux Tom , Earsom Joseph
Published: April 2023

Global governance in many domains is increasingly characterised by the existence of international regime complexes—i.e., sets of overlapping institutional fora taking up different aspects of a broader issue area. As an international actor, the EU faces a context of such international regime complexity. Yet, little is known about how the EU navigates international regime complexes and how regime complexes impact the EU’s behaviour in individual fora. This thematic issue, therefore, seeks to improve our understanding of how different manifestations of international regime complexes affect the EU as an international actor and to provide empirical insight into the ways actors like the EU navigate international regime complexes. In this editorial, we situate the thematic issue within the broader academic debates on the EU’s role in international regime complexity, argue for the need to study the EU as an actor therein, and provide an overview of the thematic issue’s objectives and the nine articles that comprise it.
NEW PRIORITIES OF GREAT BRITAIN’S FOREIGN POLICY DURING TONY BLAIR’S PREMIERSHIP
Authors:   Taras Shevchenko national University of Kyiv, Ukraine, Mashevskyi Oleh
Published: April 2023

The article analyzes the state and perspectives for the further investigation of the foreign policy of the Prime Minister Tony Blair (1997–2007). It is noted that the attention to the problem is caused both by Great Britain’s support of Ukraine in resisting russian full-scale invasion, and by the high level of activity of T. Blair and his Institute for Global Change, which are actively engaged in the development of concepts regarding a new vision of the place of post-Brexit Great Britain in the world. At the same time, they support Ukraine, actively analyze the importance and impact of russia’s war against Ukraine on the international world and security situation. The work outlines the traditional and new investigations of foreign historians who multifacetedly have scrutinized and continue to research the problems of the foreign policy of Great Britain during the prime ministership of Tony Blair. The formed scientific discourse on the relations of Great Britain with the USA and the EU countries, the problem of Great Britain’s participation in the Iraq war is highlighted. This discourse is marked by a reassessment of observed events, the formation of non-conventional approaches to problems, which is of particular interest and provides prospects for further research. Ukrainian historians continue to research issues of Great Britain’s foreign policy. Emphasis in works devoted to T. Blair’s foreign policy is usually placed on issues of Great Britain’s relations with the USA and the EU, Great Britain’s participation in the Iraq War and a number of military conflicts. The urgent need to form a scientific discourse, systematic, active scientific discussion at conferences and round tables is stressed. The author reveals the aspects of the British foreign policy which have to be investigated in the Ukrainian historiography: the cooperation with the Latin American countries (economic and political motives and interests, for instance, his visit to the states of the region, he was the first British Prime Minister who visited Argentina since the Falklands War), Blair`s interest in the time of his premiership towards the African countries (the creation of the Commission for Africa in 2004) and, especially, his lobbying of the initiatives during his heading in the G8. The article emphasizes the active use of a number of tools of public diplomacy, mass media by T. Blair, his understanding of the world’s globalization trends, and active support of these trends through economic, political and other levers. Moreover, the aspects for the further investigation are mentioned and characterized.
«CULTURAL AND ЕDUCATIONAL SECTION» IN THE CAMP FOR INTERNED SOLDIERS OF THE UGA AT JOZEFOV, CZECHOSLOVAKIA (1921-1922): ORGANIZATIONAL AND EDUCATIONAL ACTIVITIES
Authors:   Borys Grinchenko Kyiv University, Sribnyak Іhor , Chlebina Anna ,   National Library of the Czech Republic  Prague, the Czech Republic
Published: April 2023

The article discusses the organizational and educational activities of the «Cultural and Educational Section» in the Jozefov camp (Czechoslovakia), and especially its teachers’ unit. Thanks to the efforts of its members, the work of several educational centers (literacy schools, gymnasiums, and seminaries) was organized, and the teaching of educational courses aimed at different groups of internees was started. The main task of all educational courses was the preparation of the internees for their future life activities in civilian conditions – after the liquidation of the Jozefov camp. The campers without complete secondary education got the opportunity to attend educational courses, and after graduation (provided they successfully pass the final exams) they could apply for admission to high schools in Czechoslovakia. At the same time, in addition to secondary school courses, the members of the teachers’ unit conducted a range of general educational and special lectures, which were attended by hundreds of interned Ukrainian soldiers. The internees had a lot of opportunities to organize their self-education, including the using of the camp library. The intensity of the turnover of books borrowed by the internees testified to their knowing of the impermanence of their stay in the camp and the need to acquire additional knowledge. With a view to facilitate access to books for certain groups of internees, some groups (such as the Subaltern’s section or the Lawyer’s section) founded and maintained their own libraries, which were intended exclusively for the needs of their members. The education and self-education became a consolidating factor for camp residents and a kind of «tool» that allowed them to overcome all the disadvantages of camp existence. At the same time, the internees, by acquiring knowledge in its various fields, received a lot of opportunities for adaptation to the new life’s conditions in Czechoslovakia. The acquisition of high school education by the former internees (after they left the camp) allowed them to successfully integrate into the Czechoslovak society at that time and provide themselves with a decent life and living conditions.

Published: April 2023

Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. The most common neurological symptoms are headaches presenting with meningitis, meningoencephalitis, or encephalitis; however, transverse myelopathy and polyneuropathy are rare in typhoid infections. Herein, we report a laboratory and electrodiagnostically proven case of subacute myelopathy and polyneuropathy with slow progression after scrub typhus infection. A 64-year-old man complained of truncal numbness and a burning sensation in both feet. Magnetic resonance imaging did not reveal any definite changes in the spinal cord; however, serological tests showed immunoglobulin G antibodies against O. tsutsugamushi by enzyme-linked immunosorbent assay. An electrophysiological study showed myelopathy concurrent with polyneuropathy. To the best of our knowledge, this is the first immunochemical detection of antibodies in a patient with delayed neurological manifestations after scrub typhus infection.

Para o desenvolvimento do trabalho buscou-se inicialmente o cadastro das construtoras associadas ao Sinduscon-JP. De posse desse cadastro entrou-se em contato com as construtoras para agendar as entrevistas. Fizeram parte da pesquisa 28 empresas. Com o formulário elaborado procedeu-se com as entrevistas às construtoras. Foram coletados, paralelamente, documentos, mapas e leis municipais que tratam sobre o tema trabalhado, a fim de auxiliar na análise e interpretação dos dados. Através da análise concluiu-se que na grande João Pessoa existem fatores referentes à legislação que favorecem o acréscimo dos valores das edificações em determinadas áreas. Foi diagnosticado também a concentração de habitações verticais tanto nos bairros da orla marítima como nos bairros próximos que possuem acesso facilitado às praias. Essas regiões são denominadas de zonas adensáveis prioritárias e possuem os mais altos valores dos imóveis. Por essa razão, as construtoras mantêm sua preferência em construir nessas regiões, tendo em vista que são as mais procuradas por clientes que possuem maior poder aquisitivo.
Is Climate Change Affecting the Monsoon Months in Pune, India?
Authors: Shah Shalaka , Londhe Shreenivas
Published: April 2023

It is the need of the hour to study the changes occurring in the future rainfall trends for the Pune metropolitan region. General Circulation Models (GCMs) are used to study the variations in the climatic conditions occurring in the near and far future. GCMs yield the values of the required parameters over specific grid points which are not location specific and need to be downscaled. The current study suggests Artificial Neural Networks (ANN) as a tool for statistical downscaling. 5 precipitation causative parameters were mined from 5 GCMs each and then used as input to the neural networks, with the observed historical monthly cumulative precipitation as output. The best model was then used estimate the rainfall that would occur in the near future for Pune. The future rainfall analysis showed that the intensity of rainfall seems to be increasing for the non-monsoon months and decreasing for the monsoon months.
Challenges of Groundwater Development for Towns and Big Cities Water Supply in Rift Valley Areas
Authors: E Assefa , A Tenalem , A Tilahun
Published: April 2023

The experiences of the last 30 years developed an understanding in the Addis Ababa Water Utility that groundwater sources are not fully dependable for such a big city. Notwithstanding this, additional wells and well-fields are being developed especially in the last 10 years to meet the ever increasing demand. The Akaki well-field was initially designed for an abstraction rate of up to 35,000 m3/day for 20 years until 2020 though the current abstraction rate is nearly ten-fold. The current developments are only demand driven irrespective of safe and sustainable utilization. What is making things worse is the rise of other water competing demands for irrigation projects in adjacent well-fields. The present water supply coverage of the Addis Ababa city is not more than 50%. The situation in other urban centers in the Upper Awash basin is not different. Conceptual modelling, time series well water level measurements and operational assessments showed that the aquifer systems are not uniform and dotted with many volcanic flow barriers; there is sharp decline of water table (up to 70 meters since 2000) in some well-fields and the decline is propagating upstream of the Akaki well-field. Moreover, the excessive and uncontrolled pumping is impacting regional groundwater table. Topographic and technical issues are hampering upstream water distribution, and the once exemplary hundreds of wells are now abandoned. The frequent tapping of thermal and high fluoride water is another complication. Unless proper intervention is devised, grave environmental problems are likely to come in the near future.
The adaptive market hypothesis and the return predictability in the cryptocurrency markets
Authors: Karasiński Jacek
Published: April 2023

This study employs robust martingale difference hypothesis tests to examine return predictability in a broad sample of the 40 most capitalized cryptocurrency markets in the context of the adaptive market hypothesis. The tests were applied to daily returns using the rolling window method in the research period from May 1, 2013 to September 30, 2022. The results of this study suggest that the returns of the majority of the examined cryptocurrencies were unpredictable most of the time. However, a great part of them also suffered some short periods of weak-form inefficiency. The results obtained validate the adaptive market hypothesis. Additionally, this study allowed the observation of some differences in return predictability between the examined cryptocurrencies. Also some historical trends in weak-form efficiency were identified. The results suggest that the predictability of cryptocurrency returns might have decreased in recent years also no significant relationship between market cap and predictability was observed.
Analysis of Features and Methods for Data Delivery Routes Determination in the Wireless Self-Organizing Networks Based on the Unmanned Aerial Vehicles
Authors: Kulagin G.I.
Published: April 2023

Currently, one of the promising areas in the development of network technologies is the wireless self-organizing networks based on the unmanned aerial vehicles, i.e., FANET (Flying Ad-Hoc Networks), which most important task in the course of their operation lies in organizing the effective data exchange. The distinctive properties of wireless self-organizing networks with altering topology are leading to the fact that technical solutions and methods of determination of the data delivery routes used in telecommunication networks with the traditional fixed architecture turn out to be inefficient in the special FANET networks and are not able to provide the required performance. At the same time, wireless self-organizing networks based on the unmanned aerial vehicles possess their own techniques used in data routing, which are subject to the requirements that take into account characteristic differences inherent in the networks of this type, including high mobility and low density of the nodes, dynamic and frequent topology alterations. Features and methods for determining data delivery routes were analyzed in the wireless self-organizing networks, which basis (nodes) were the unmanned aerial vehicles
El Derecho Internacional Económico en el Mundo Contemporáneo
Authors: Díaz Albónico Rodrigo
Published: April 2023

Al aceptar esta amable invitación, uno no prevé las dificultades intrínsecas que existirían al tratar una materia que -no obstante haber pa- . sado ya más de cuarenta años- todavía es difícil de definir. La tarea es aún más compleja porque toda definición tiene algo de negativo: delimitamos un ente con respecto a otros, porque negamos los otros hasta quedarnos mentalmente con el ente definido. Con estas dificultades y teniendo presente la novedad que presentaban estas materias en los años 50, los principales autores que trataron lo que hoy conocemos como "Derecho Internacional Económico", escogieron primeramente una aproximación relativamente simple: enumerar las materias que abarcaría esta nueva fracción del Derecho Internacional.

Cambios Económicos y Democracia en América Latina
Authors: Tudela van Breugel-Douglas Francisco
Published: April 2023

Cuando hablamos de cambios económicos en América Latina, estamos hablando de un concepto que ha sido central en los últimos 45 años y que es el concepto de desarrollo, y esta relación entre el desarrollo y el sistema político en América Latina, es la historia, primero, de una frustración, y, en segundo lugar, es una historia que requiere ser revisada para preparar la actuación de América Latina en una época que representa una nueva era pero que, además de ser una nueva era, es una era incierta hasta este momento.
Comparing the role of the export sector in Prehistoric economies : the importance of shell manufacture to the livelihood of coastal Ecuadorian populations

Para comprender la evolución de las culturas prehistóricas es indispensable analizar el desarrollo de la producción especializada. Observando qué tipo de sociedades prehistóricas permitían que sus individuos o grupos de individuos se retiraran de la economía de subsistencia para llevar a cabo exclusivamente una sola tarea y cuáles no, podemos incrementar nuestro conocimiento sobre los procesos que llevaron hacia la formación de las economías altamente especializadas típicas de la era moderna.
Regional patterns of fortification and single forts : evaluating the articulation of regional sociopolitical dynamics with localized phenomena
Authors: Brown Vega Margaret
Published: April 2023

Después de más de cinco décadas de investigaciones en varios valles costeros de Perú, existen abundantes datos de reconocimiento que pueden ser utilizados para resolver problemas antropológicos en una escala regional. Dadas las herramientas con las que contamos hoy en día-como los sistemas de información geográfica y las computadoras de alto nivel de procesamiento-para llevar a cabo análisis en estas bases de datos, es más factible llevar a cabo estudios regionales e incluso de áreas mayores (Kantner 2008:43-44). Sin embargo, antes de poder analizar la información, esta debe ser compilada de manera que permita su análisis.
De Arguedas a Rivera Martínez : evolución y renovación del canon de la literatura indigenista peruana
Authors: Márquez Ismael P.
Published: April 2023

Desde la aparición de Los ríos profundos (1958) de José María Arguedas, novela considerada como iniciadora del neoindigenismo, la narrativa neoindigenista peruana ha transcurrido por cauces que naturalmente se entrecruzan e interconectan conformando un sistema autogenerador expansivo y dinámico.
Notas acerca de la narrativa 'neo-indigenista' posterior a 1971
Authors: Escajadillo Tomás G.
Published: April 2023

El caso de Edgardo Rivera Martínez (Jauja, 1933), y su posible vinculación con el neoindigenismo, merece un aparte. Aunque su primer libro, El unicornio (Lima, s.p.i. impreso en la imprenta de UNMSM- 1964), es anterior al reconocimiento de su narrativa, es un fenómeno de la década de los '70.
Edgardo Rivera Martínez : y lo real maravillloso en el ande
Authors: González Vigil Ricardo
Published: April 2023

La publicación de Azurita (Lima, Lasontay, 1978; 149pp.) está destinada a consagrar definitivamente el nombre de Edgardo Rivera Martínez entre los cuentistas peruanos en actividad. El reducido tiraje de sus obras anteriores (El unicornio, 1963, y El visitante, 1974) ha conspirado hasta ahora escatimándole el reconocimiento que reclama.
Raíces y rizomas en los relatos de Edgardo Rivera Martínez
Authors: Schwalb Carlos
Published: April 2023

Muchos de los personajes en los cuentos de Edgardo Rivera Martínez se asemejan al niño que camina perdido en la oscuridad y construye un hogar provisorio con su canto: son huérfanos; viajeros que llegan de tierras lejanas; exiliados; apátridas. No tienen un hábitat y se encuentran, literal y metafóricamente, en medio de un camino, amenazados por una noche que no sólo es exterior.

Nombre del país : el nombre
Authors: Cornejo Polar Antonio
Published: April 2023

Me pregunto si Edgardo Rivera Martínez ha escrito País de Jauja o si Jauja ha escrito a Rivera Martínez. Con lo primero no digo más que una obviedad, por cierto; con lo segundo, en cambio, trato de responder a una antigua inquietud frente a lo que hasta ahora parecía ser la norma de la tersa, fina y honda narrativa de Rivera Martínez, casi siempre repartida, y a veces minuciosamente, entre textos enraizados en el mundo andino.
