“E FORAM FELIZES PARA SEMPRE”
Authors: Rodrigues Thiago Martins
Published: December 2024

O presente trabalho tem como objetivo analisar, na perspectiva dos debates sobre masculinidades negras, as trajetórias dos personagens da novela Dois amores, de Paulo Lins (2019). A partir dessas discussões contemporâneas, que voltam suas atenções para constituição da identidade dos homens negros em meio a uma realidade colonizada, a hipótese aventada é que a sociabilização dos protagonistas da obra, Lulu e Dudu, opera dentro de um espectro colonial opressivo que os leva à interiorização de ideais de amor, de beleza e de consumo pautados por uma masculinidade hegemônica e que se torna violenta diante dos diversos entraves sociais colocados para jovens negros periféricos.
ATLANTISMO EM MANUTENÇÃO: UM BALANÇO DA PARCERIA ENTRE BRASIL E CABO VERDE DURANTE OS GOVERNOS DILMA ROUSSEFF (2011-2016)
Authors: Reis Silva Tatiana Raquel , Chaves Batista Leandro
Published: December 2024

O presente trabalho busca compreender as principais ações de cooperação e diplomacia entre o Brasil e países do continente africano, com destaque para o arquipélago de Cabo Verde. O estudo tem como recorte os anos de 2011 a 2016, período de governança de Dilma Rousseff na República Federativa do Brasil, marcado pela manutenção de uma política africana fixada anteriormente, mas com relativa inflexão, sobretudo quando comparado ao governo anterior, de Lula da Silva (2003-2010). A documentação utilizada abrange dados do portal da Agência Brasileira de Cooperação (ABC), notadamente no que diz respeito aos projetos implementados; dos relatórios financeiros Cobradi, elaborados pelo Instituto de Pesquisa Econômica Aplicada (IPEA), no que concerne aos dispêndios do governo federal brasileiro com a cooperação; da Biblioteca Nacional da Presidência, marcadamente viagens presidenciais e discursos diplomáticos; e, de modo acessório, o sumário executivo de iniciativas Brasil-Cabo Verde, disponibilizado pela ABC. Por meio da caracterização da parceria entre Brasil e Cabo Verde, explorando a cooperação técnica desenvolvida, infere-se que, embora com menos vigor, a política externa brasileira para a África durante os anos Rousseff produziu atividades relevantes para o contexto de governança sincrética no Sul Global.
THE AMALGAMATION OF 1914 AND THE NIGERIAN CIVIL WAR: THE BURDEN OF BLAME
Authors: Oyarinu Abimbola
Published: December 2024

In the face of daunting challenges facing the Nigerian state, in terms of civil unrest, poverty, under-development, terrorism, militancy, etc, there is more than enough evidence to show that the foundation of these problems was cast long before Nigeria’s independence. This perhaps sheds immense light on the origin and complexity of the Nigerian problem. However, the ruling class is repugnant to open the Pandora box, so as not to divide a country, which is already divided. The study adopts the structural political economy theory to understand the role of the British and Nigerian political elites in shaping Nigeria’s fate. Using the eventuality of the Nigerian civil war with recourse to the historical analytical method of qualitative research, this paper traces the origin of Nigeria’s problem to the British and British pronouncement of 1914. It further argues that if the issues of our union as a nation are not treated, there will be more internal strife, corruption and underdevelopment in Nigeria.
O LINGUISTA E O INCONSCIENTE
Authors: Flores Valdir do Nascimento
Published: December 2024

Este texto busca avaliar as relações entre a linguística e a psicanálise a partir de um ponto de vista muito específico: a obra da linguista francesa Claudine Normand. Inicialmente, são apresentadas as ideias da linguista presentes em vários trabalhos, em seguida faz-se uma proposta de entendimento desse conjunto de ideias com vistas ao deslocamento do assunto do âmbito disciplinar – linguística e psicanálise – para o âmbito dos efeitos da admissão, para o linguista, da hipótese do inconsciente e de sua incidência no fazer do linguista.
A LINGUAGEM COMO CONVERTIGEM
Authors: Rodrigues de Souza Cirlana
Published: December 2024

Considerando o inconsciente estruturado como uma linguagem, o objetivo é recortar do texto O Aturdito (LACAN, 1972/2003) elementos que possibilitem ler e escutar esse inconsciente como existência de linguagem.  Do jogo de significantes, dos efeitos de sentido e significação, o equívoco afeta o ser falante por ressoar rompendo o peso da palavra do Outro e sua potência alienante de sentidos. O equívoco como funcionamento de linguagem será abordado dentro da perspectiva psicanalítica a partir das dimensões do dizer real, simbólico e imaginário geridas pela lógica do objeto a, que não se nomeia, mas ordena as análises e redefine a interpretação. Ao final, será tirada a consequência dessa perspectiva para a articulação entre linguagem e psicanálise.
TODO MUNDO FALA PRETUGUÊS, PRINCIPALMENTE QUEM NÃO FALA
Authors: Veriato Chaves Tyara , Cestari Mariana , França Glória
Published: December 2024

Nessa escrita desejamos tocar as relações entre língua, história e psicanálise para pensar alguma coisa da ordem do cultural em nossa formação social brasileira. Para tanto, mergulhamos no imaginário em torno da trasmissão da língua materna mirando, especialmente, o que Lélia Gonzalez ([1984] 2020) batizou de pretuguês. É também a partir dessa autora, que tanto nos provoca, que também percorremos um imaginário em torno da figura da mãe preta e sua presença nesse processo de transmissão de uma língua, de uma cultura, de uma prática de resistência. Assim, do pretuguês, partimos então em direção a mais uma profundidade imersa nesse imaginário ao olhar para a canção Tia Anastácia, de autoria de Dorival Caymmi. Nesse artigo, acreditamos que seja possível pensar algumas questões mal-ditas, que fazem intervir ao mesmo tempo a dimensão das opressões históricas e das sutilezas eróticas, colocando para os analistas do discurso o incontornável de trabalhar entre as diversas materialidades discursivas, conforme Pêcheux ([1981] 2016, p. 23): “[...] daquilo que, entre a história, a língua e o inconsciente, resulta como heterogeneidade irredutível”. Assim, não propomos um sistema de respostas que apazigue o mal-dito da colonização; nossa tentativa, nessa empreitada, é de provocar a colonialidade pelas suas margens.
SOB A DERME DO IDEOGRAMA
Authors: Hayashi Renan Kenji Sales
Published: December 2024

A presente investigação trata de uma articulação entre a escrita japonesa e o fetichismo. A hipótese procura apresentar o uso do ideograma/fonograma como um objeto-fetiche. A pesquisa propõe um enlace entre a psicanálise freudo-lacaniana e a leitura de fetichismo proposta por Bhabha (1995). Dessa forma, foi feita uma problematização de situações que mostram uso da escrita japonesa via mecanismo fetichista: tatuagens e roupas. Resultados apontam para a ideia da escrita japonesa não somente inscrita na dimensão do fetiche, como também no campo do gozo.
ENTRE PÁTRIAS E PERTENCIMENTOS
Authors: Costa Carvalho Lyanna , Damasceno da Silva Nayara
Published: December 2024

Este artigo explora as interseções entre literatura e história na obra Nação Crioula de José Eduardo Agualusa. Através de dispositivos metaficcionais, o romance desconstrói a história oficial de Angola, questionando os discursos tradicionais sobre colonialismo, escravidão e formação identitária. Utilizando os conceitos de metaficção historiográfica e teoria pós-colonial, o artigo examina como a obra de Agualusa desafia a noção de identidades fixas e a narrativa linear da história. Além disso, o artigo discute como o romance aborda as complexidades da formação identitária no mundo pós-moderno e globalizado, marcado pelo fluxo de pessoas, culturas e histórias. Através de uma leitura atenta da história de amor entre Fradique Mendes e Ana Olímpia, o artigo destaca como Agualusa emprega técnicas literárias para iluminar as múltiplas camadas da identidade histórica e cultural. No geral, o artigo argumenta que Nação Crioula é um poderoso exemplo de como a literatura pode se envolver de maneira crítica com a história e a formação identitária.
A LITERATURA COMO FORMA DE PRESERVAÇÃO DA MEMÓRIA NA DIÁSPORA UCRANIANA DO ESTADO DO PARANÁ (BRASIL)
Authors: Hodik Kateryna , Fernandes Frederico Garcia
Published: December 2024

Resumo: Este artigo problematiza a questão da existência da literatura como forma de preservação da memória nacional na diáspora ucraniana do Brasil. Foram analisadas as peculiaridades das publicações em língua ucraniana e portuguesa, foram estabelecidos os princípios de compilação de textos para uso na comunidade e para a popularização da cultura entre representantes de outras nações. Foi estabelecido que os textos selecionados não são acompanhados de um amplo comentário literário, não fornecem explicações abrangentes sobre a essência da identidade ucraniana etc. Preservam uma lista limitada de símbolos nacionais, memórias do país de origem e traumas históricos, o mais importante deles é o Holodomor (1932-1933). As publicações raramente são representadas em bibliotecas devido a um método específico de distribuição e raramente são utilizadas para o estudo da literatura ucraniana em instituições de ensino superior. Isto permite dizer que o principal destinatário da literatura diaspórica são os portadores da identidade ucraniana. Os resultados do estudo dão motivos para dizer que tal forma de formação da literatura na diáspora leva ao aparecimento de livros, principalmente para uso doméstico, para preservar e transmitir a memória cultural e não contribui para a sua divulgação entre leitores de diferente identidade nacional.
Numerical and experimental study on the thermal performance of a new plate evaporator and condenser for ocean thermal energy conversion
Authors: Zhou Xiang , Sui Zhiqiang , Zhao Haichen , Yang Dingding , Wang Xiaoqi
Published: December 2024

This paper studies a new type of plate evaporator and condenser used for
ocean thermal energy conversion. The evaporator and condenser are composed
of herringbone smooth curved corrugated sheets, with interlaced arrangement.
For the evaporator, the refrigerant R134a enters from the bottom, is evenly
distributed to the flow channel between the plates, and flows out after
being gathered in the top. For the condenser the flow is the opposite. Water
enters from the upper right inlet into the channel between the plates and
leaves from the lower left outlet. This paper studies the resistance and
heat transfer characteristics of these heat exchangers by means of
simulation and experiment. It is found that this type of plate flows evenly
in the inter-plate channel, the heat exchange is reasonable, and the rate of
corresponding heat transfer and pressure drop are calculated. Through the
experimental study of the heat exchange effect of the tested plate heat
exchanger in the phase change process, it is concluded that the heat
transfer of this kind of heat exchanger under the conditions of the
evaporator and the condenser is 64.12 kW and 69.77 kW respectively, and the
rate of heat transfer is 1843 W/m2?K and 2104 W/m2?K.

Today, among renewable energy sources, solar power is particularly effective. It is known that solar panels are mainly (more than 95%) based on monocrystalline or polycrystalline (sometimes amorphous) silicon, as a unique semiconductor material. Its irreplaceability is explained by its prevalence in nature. at the same time, the technology of manufacturing silicon solar cells is quite complex and energy-intensive. Therefore, scientists of the world today are working on the search for new materials, in particular, binary, ternary, non-stoichiometric and other compounds They also have satisfactory electrophysical characteristics. however, at present, these tandem and more complex materials have, compared to silicon, significantly lower efficiencies and problems with the timing of their operation. In addition, the absolute majority of them are rare in nature and therefore industrial production is quite problematic.

This study employs state-of-the-art analytical tools to investigate the ecotoxicological impacts of mercury contamination on aquatic macrophytes in post-military zones, focusing on Typha latifolia and Lemna minor as model organisms. The research methodology integrates multiple analytical techniques: spectrophotometric chlorophyll quantification using the Holm-Wettstein method, atomic absorption spectrometry utilizing a C-115PK Selmi spectrometer (precision ±0.001 mg/L), and fluorescence analysis via Flyuorat-02-Panorama spectrofluorometer. Through this comprehensive analytical approach, we elucidated the bioaccumulation patterns and physiological responses of these hydrophytes to varying concentrations of mercury (0.35-2.0 mg/L). Results demonstrated differential bioaccumulation capacities between T. latifolia and L. minor, with the latter exhibiting higher mercury sequestration potential (0.51 mg/kg vs 0.4 mg/kg dry weight). Concentration-dependent phytotoxic effects were observed, manifesting as morphological alterations, chlorophyll degradation, and disruption of photosynthetic processes. Notably, a consistent increase in the chlorophyll b to chlorophyll a ratio was documented, indicative of selective degradation of photosystem II under mercury stress. The study further revealed the inactivation of key Calvin cycle enzymes, leading to attenuated carbon fixation and overall photosynthetic capacity. These findings not only elucidate the mechanistic underpinnings of mercury toxicity in aquatic macrophytes but also underscore their potential as bioremediators in mercury-contaminated aquatic ecosystems. The research provides critical insights for developing targeted phytoremediation strategies and ecosystem restoration protocols in post-military aquatic environments.

Published: December 2024

Ecological and economic consequences of a full-scale Russian invasion of Ukraine are difficult to define, outline and quantify because the destructive war continues. For the post-war period, there will be a need to rebuild cities that were destroyed as a result of Russian aggression; at the design stage, it will be relevant to make proposals for the formation of green-blue infrastructure and implementation of eco-oriented solutions in all settlements of Ukraine, in particular, in Kamianka-Buzka city. The analysis of scientific publications on the formation of green-blue infrastructure was carried out and its functional potential was determined; based on the list of basic eco-oriented solutions, a number of proposals were made for the implementation of eco-oriented solutions in the city of Kamianka-Buzka. Given the current environmental situation, priority measures for the implementation of eco-oriented solutions in the city are: increasing the number and density of green areas, placing forest strips along roads, cleaning water surface runoff, modernizing parks, water supply and drainage systems, setting up a river embankment. Strengthening the role of green and blue infrastructure is a growth point that will help Ukrainian cities become more sustainable, progressive, comfortable and developed in the future.

This article presents the results of experimental studies investigating the energy consumption per 1 kg H2O required for the filtration drying of beet pulp. The optimal process parameters for the removal of 1 kg of moisture from the dried beet pulp were determined, which included the height of the layer of dried material H=120 mm, the thermal agent temperature T = 90 °C and the thermal agent velocity v0 = 1.76 m/s. Regarding these parameters, the total energy consumption for drying by the filtration method from the initial moisture content of 88.12 % wt. to the final moisture level of 14 % wt. is 3,515 kW·h/kg H2O. Based on the experimental data, a calculation was made for an industrial filtration drying unit, for which the cost of removing 1 kg of moisture from beet pulp was determined: 3,28 kW·h/kg H2O. To evaluate the efficiency of the filtration drying process, we conducted a comparative analysis of the drying of beet pulp at a comparable capacity in a drum dryer. According to the calculations, the energy costs for removing 1 kg of moisture from beet pulp in a drum dryer are 3.11 kW·h/kg H2O. Considering the estimation of calculations and a significant reduction in the drying time with the filtration method (~10 times), it is possible to conclude that filtration drying is a beneficial and efficacious technique for beet pulp drying.

Penelitian ini memiliki tujuan utama untuk melakukan tinjauan strategis terhadap pemindahan ibu kota negara Indonesia ke wilayah Kalimantan Timur, yang mana tinjauan difokuskan dalam aspek geopolitik ibu kota Nusantara, potensi ancaman yang muncul dari kompleksitas keamanan di kawasan Indo-Pasifik, hingga bagaimana perkembangan strategi pertahanan untuk membentuk masa depan ibu kota Nusantara. Penelitian ini menggunakan teori Realisme Defensif dari Kenneth N. Waltz, serta Teori Regional Security Complex dari Berry Buzan untuk menunjukkan bahwa keamanan nasional tidak dapat diraih apabila suatu negara tidak memperhatikan keamanan regional. Temuan dan analisis studi menunjukkan bahwa secara geostrategis posisi ibu kota Nusantara sangatlah rawan, hal ini dikarenakan posisinya yang ada di pusat kawasan Indo-Pasifik dengan segala isu keamanan yang ada. Pada kondisi ini matra udara dan laut menjadi sumber ancaman utama mengingat perkembangan konflik Amerika Serikat dan Tiongkok, sehingga pengembangan strategi pertahanan difokuskan pada pembentukan sistem pertahanan berlapis dan peningkatan sistem pertahanan udara.

Hasilnya, peneliti melihat blokade pelabuhan Ukraina tahun 2022 sebagai aksi balasan Rusia untuk mengembalikan situasi ekonomi yang mengalami kemerosotan sejak tahun 2014. Blokade menjadi faktor pendorong dalam sistem pangan, memengaruhi stabilitas dan ketersediaan pupuk Indonesia. Gangguan rantai pasokan hanya berdampak pada lonjakan harga pupuk saat konflik, secara signifikan tidak mengakibatkan kerugian yang besar pada petani. Analisis ini didasarkan oleh temuan data impor pupuk Rusia yang justru meningkat pada tahun 2022-2023 dan respons cepat pemerintah Indonesia dalam ancaman penurunan volume pupuk serta lonjakan harga pupuk global.
música como lugar de un tiempo psicológico constituido por la técnica
Authors: Carvallo Pinto Antonio
Published: December 2024

La propuesta de Gilles Deleuze para la música de Hacer audibles fuerzas que en sí mismas no lo son encuentra como fuerza privilegiada al tiempo mismo, un tiempo ya definido por Bergson cómo heterogeneidad y que se dispone no sólo para nuestra conciencia, sino también para nuestros sentidos. Es así como, en cuanto la música se despliega para la sensibilidad en el tiempo de la conciencia, la experiencia musical se alza como territorio privilegiado para conocer cómo se produce la configuración del tiempo psicológico. Intentando develar los aspectos de la música que modelan el tiempo de la conciencia se abordará la relación establecida por Heidegger entre tiempo y técnica, dos modos de sacar de lo oculto.

Bu çalışmada Trabzon İli Akçaabat İlçesi sınırları içinde meydana gelen kaya duraysızlıkları değerlendirilmiştir. İlk aşamada, analizlere altlık oluşturması için İnsansız Hava Aracı (İHA) ile yapılan uçuşlardan çekilen fotoğraflar kullanılarak çalışma alanı ve çevresinin nokta bulutu verileri üretilmiştir. Sonrasında fotogrametrik yöntemler kullanılarak üretilen bu nokta bulutundan arazinin sayısal arazi modeli oluşturulmuştur. Çalışma alanı, litolojik özellikler, morfoloji, yerleşim durumu, bitki örtüsü ve alınabilecek önleme ve/veya koruma yöntemleri dikkate alınarak 3 bölgeye ayrılmış, hat etüdü yöntemi ile süreksizlik özellikleri belirlenmiştir. 270/85 duruşlu kaya şevinde, 264/78 duruşlu süreksizlikler boyunca düzlemsel kayma-doğrudan devrilme, 213/71 ile 324/68 duruşlu süreksizliklerin ara kesit doğrusu boyunca kama tipi kayma riski olduğu kinematik analizlerle belirlenmiştir. Yapılan limit denge analizlerinde dinamik durum için en düşük güvenlik sayısı değeri 1,29 olarak hesaplanmış, 3 farklı bölgede de kayma ve devrilme riskinin olmadığı görülmüştür. Ancak, Bölge-1 ve Bölge-2’de arazi çalışmaları sırasında vadi içerisinde gözlenen kaya blokları, bölgede geçmiş dönemde kaya düşmesi olaylarının yaşandığına işaret etmektedir. Öte yandan kaynak zonda bulunan süreksizlikler ile sınırlanmış bloklar kaya düşmesi açısından risk oluşturmaktadır. Kaya kütlesinin mostra verdiği Bölge-3’te süreksizlikler ile sınırlanmış olan kaya bloklarının ve üst zonlardan gelip bu bölgede duran blokların olası hareketi söz konusudur. Vadi içlerinde biriken bloklar için yapılan 3 boyutlu kaya düşme analizleri sonucunda Bölge-1’deki vadi ağzına 14 metre uzunluğunda, Bölge-2’deki vadi ağzına ise 25 metre uzunluğunda ve 3 metre yüksekliğinde perde duvar yapılarak etkilerinin azaltılacağı belirlenmişti. Bölge-3’te bulunan riskli blokların hareketini önlemek için ise üst yarıdaki alan için 180 m2’lik çelik ağ kullanılması durumunda, kütle hareketi riskini minimuma indirgeyeceği sonucuna varılmıştır. Böylece çalışma sahasındaki olası duraysızlık riskleri değerlendirilerek farklı ıslah çözümlemeleri bir arada efektif bir şekilde kullanılmış olacaktır. Önerilen birleşik kaya ıslah projeleri sayesinde kaya düşme riskleri ortadan kalkacaktır.
Grain yield, grain quality and weed infestation of winter wheat after various previous crops
Authors: Woźniak Andrzej
Published: December 2024

Grain yield and quality as well as the weed infestation of winter wheat grown after potatoes, peas and winter wheat were evaluated in the study. The experiment was established in a system of randomized blocks, in three replications. The experimental results were statistically processed via the analysis of variance method. Coefficients of Pearson’s linear correlation between grain yield and its components, grain quality parameters, and the number and air-dry weight of weeds were also calculated. Grain yields of winter wheat were higher when it was grown after potato and pea than after winter wheat. In addition, winter wheat grains harvested from plots with potato and pea as previous crops had a higher total protein content and a higher sedimentation index than those harvested from plots with winter wheat as the previous crop. However, the study years affected the protein, gluten and starch contents of winter wheat grain to a greater extent than the previous crops did. A higher number of weeds with a higher air-dry weight was recorded on the post-winter wheat than on the post-potato and post-pea plots. Negative values of correlation coefficients were computed between the number of weeds and their air-dry weight and grain yield, number of spikes, grain weight per spike, 1000 grain weight, total protein content of the grain, and the value of sedimentation index as well as between weed number and wet gluten content of the grain.

In a 2-year field study, the impact of mineral nitrogen fertilization on the productivity of a new potato cultivar, promising due to the highest resistance to potato late blight among the registered ones, was compared to the proven, widely cultivated Denar cultivar. The study determined morphological features (size and weight of organs), physiological indicators (cover of soil by leaves – LAI. leaf greenness – SPAD) of potato plants during the growing season, yield and quality characteristics of tubers and optimal level of nitrogen fertilization. Tuber quality was assessed based on the share of tuber size and external defects in the yield structure. Optimal mineral nitrogen fertilization was determined based on the relationship between the increase in tuber yield and the increasing dose of this ingredient. The research took into account two factors: nitrogen dose (0, 50 kg‧ha–1, 100 kg‧ha–1, 150 kg‧ha–1) and cultivar (Gardena and Denar). The increase in the dose of mineral nitrogen fertilization to 150 kg‧ha–1 resulted in a significant increase in plant height, the weight of the root system, stems, leaves and the share of large tubers in the yield. It was shown that the Gardena cultivar was characterized by greater requirements for mineral nitrogen fertilization, low effectiveness of its use, a higher share of large tubers (diameter above 60 mm) and lower tuber yield than the Denar cultivar. In a year characterized by excess rainfall, plants produced a greater mass of the root system and the mass of the above-ground part, and in a year with an amount of rainfall close to optimal the final yield of tubers and the share of large tubers in the yield were higher.

Published: December 2024

For centuries, the Saharan oasis agro-systems of Adrar region have fed many generations, based on an original organization, based on the efficiency of drainage water on the diversification of crop systems in association with small livestock farming. The aim of the work is to describe the systemic typology of oasis livestock farming in the Adrar region (southwest Algeria). In order to assess the livestock typology, a series of surveys were conducted on 164 farms in the oases of the study region. The analysis reveals that the production system, traditionally aimed at subsistence agriculture. The dominant production system is an intensive system, characterized by intensive mixed food crops (Phoenicuculture, arboriculture, herbaceous crops: cereals, fodder, market gardening, industrial and condiment crops), in association with livestock farming mainly of small ruminants (goats and sheep). The livestock system is characterized by a family type, small in size in traditional management. It is generally managed in stalls and its feed comes mainly from fodder crops, domestic waste and by-products of palm groves. Family livestock farming can be an important source to ensure a certain production of animal origin (milk and meat) for family self-consumption. As a result, it can contribute to ensuring food security, family financial security and improving soil fertility in oasis farm plots.

Published: December 2024

The present work aims to illustrate the current state of steppe rangelands based on three plant formations: Stipa tenacissima, Lygeum spartum and Stipagrostis pengens, and to describe the different floristic processions linked to these species in Nâama region with an arid climate. The phytoecological study is based on qualitative and quantitative analyses through 150 floristic surveys carried out during the spring period of the year 2022 in Nâama region. The floristic analysis enabled the identification of 62 taxa belonging to 23 families and 53 genera. The floristic procession is very rich and diverse in the three plant formations according to the Shannon indices (between 2.85 and 3.59) and equitability (0.68 and 0.86), where Asteraceae and Poaceae dominate the herbaceous layer in the study area. The three plant formations have great ecological plasticity and occupy an important place in the steppe rangelands of Naama. They tolerate extreme environmental conditions (drought, aridity, sandy substrates) well through adaptations using various strategies for occupying these specialized environments. The floristic evaluation of the steppe rangelands is necessary, even mandatory; in order to assess the pastoral potential and to identify solutions for the restoration and rehabilitation of these degraded steppe areas.

In recent years, humans have turned to herbal remedies to solve a variety of problems, both food-related and health-related. Synthetic food preservatives are now restricted in many developed countries because of their irreversible effects on the body. Therefore, the present study is an important contribution to the search for new beneficial preservatives from plants. The Citrus aurantium plant is widely used by the people of the Relizane region for therapeutic and culinary purposes. The extraction of essential oils from the fruit of this plant by hydro-distillation gave a yield of 0.09 ± 0.01%. The relative density at 20°C, the acid value, the ester value and the saponification value are in the order of 0.69 ±0.1, 44 ±3.0 mg KOH/g oil, 2.75 ± 0.5 mg KOH/g oil and 46.75 ± 5.1 mg KOH/g oil respectively. GC/MS analysis revealed the predominance of linalool (43 ± 1.5%) followed by limonene (19 ± 3%). In contrast, no alterations were detected in sample 3 in terms of odour, appearance and colour. A low number of total aerobic mesophilic flora (2×104 CFU/g) was recorded in the same sample, followed by sample 2 (4!!!x0020;× 104 CFU/g) and sample 1 (6 × 106 CFU/g). A total absence of Salmonella and Staphylococcus aureus in samples 3 and 2. While sample 1 appeared spoiled due to the presence of a load of 104 CFU/g of Salmonella. The Citrus aurantium essential oils appear to be a natural preservative that can be used and incorporated into many perishable food preparations.

In the early 2000s, the European Commission laid the groundwork for soil protection with a report titled “Towards a Thematic Strategy for Soil Protection”[1]. This report outlined guidelines for preserving and enhancing soil quality. As a result, understanding the levels of heavy metals in soils and their sources became a key priority for the European Union. The main objective of this study is to investigate the effect of pesticide and insecticide use on the soils of the main orchards in Dambovita County. Using WDXRF spectrometry, the elemental concentrations of As, Cd, and Pb were determined in samples collected from 10 points located in the main orchards of Dambovita County. The distribution maps obtained, as well as the comparisons made with the maximum allowable limits of pollutant elements in soils, demonstrated the impact that pesticide and insecticide use can have on soil.

The breeding and management of birds has represented throughout history the main occupation with regard to obtaining as quickly as possible, quantitatively but also qualitatively, valuable animal products high economic. During the study, the technological circuit within the production hall for raising broilers was monitored, in terms of managing microclimate factors in direct correlation with physiological needs of broilers as well as the evolution of hybrids, from the moment of population until reaching the specific marketing age, The proposed objective was to present the advantages of the stage rearing system to the detriment of the classic system, on permanent litter. Although this new model is not very popular among large farms due to the high implementation costs, it offers significant advantages regarding broiler health, microclimate conditions, easier manure disposal operations and shorter time required for preparation. of the rearing rooms until the next population. Ventilation, insulation or heating are the primary parameters regarding the adaptability of the chicks to the exploitation conditions. Neglecting any such factor can jeopardize the smooth running of the activity and can negatively affect biosecurity.
Revisiting Czech philosophical critiques of science in the age of Generative AI and Big Data
Authors: Brennan Daniel
Published: December 2024

This paper explores the resurgence of anti-scientism in contemporary debates surrounding the COVID-19 pandemic, Big Data, and Generative AI, drawing parallels with 20th-century Czech philosophical critiques of scientism. The work of Czech intellectuals such as Tomáš G. Masaryk, Karel Čapek, Josef Šafařík, Jan Patočka, and Václav Havel is revisited to understand how their concerns about the dominance of scientific rationalism remain relevant today. The paper critiques both the blind faith in science as a comprehensive solution to complex human problems and the reductive dismissal of science as a tool of control. It argues for a nuanced middle ground that recognizes the value of scientific inquiry while also emphasizing ethical, spiritual, and humanistic considerations. By engaging with these Czech perspectives, the paper proposes a framework for critically navigating the interplay between ethics, technology, and human values in the face of contemporary challenges such as pandemics, AI, and climate change. This approach challenges both scientific and anti-scientific extremism and advocates for a balanced discourse that integrates wonder, ethics, and critical inquiry.

Research background

The number of small agricultural enterprises in Ukraine has been decreasing in recent years, and their share in the total volume of production and sale of agricultural products has remained stable at a relatively low level. At the same time, there is a public demand for the growth of the role of small agricultural enterprises, which can perform important economic and social functions. Ensuring the effective development of small agrarian business entities involves the use of strategies and approaches that take into account the specifics of the relevant groups of agricultural producers.

Purpose

The purpose of the paper is to justify the prospects of small agrarian business in Ukraine, taking into account the trends of its development, including in the conditions of martial law.

Research methodology

The research used data from the State Statistics Service of Ukraine. The research methodology is based on the general dialectic approach and includes the following methods: induction, deduction, analysis of dynamic series, and graphical.

Results

The peculiarities of the formation of the contribution of small agricultural enterprises into the supply of agricultural products in Ukraine are revealed. A generally high level of economic efficiency, a satisfactory level of technological efficiency and a relatively low level of social efficiency of small farms were established. Prospective strategies for the development of various categories of small agricultural enterprises are outlined, taking into account the mechanisms and sources of their support, which can be used in the conditions of martial law and the post-war period. The application of these strategies can ensure positive socio-economic changes in the agricultural production system of Ukraine.

Novelty

A differentiated assessment of the results of the activities of small enterprises and individual entrepreneurs in the agricultural economy of Ukraine in the pre-war period and in the conditions of martial law was carried out. The prospects for the development of small farms in the post-war period are outlined, taking into account changes in the environment of their operation and the application of separate regulatory instruments.

Authors: Żebrowska-Suchodolska Dorota
Published: December 2024

Research background

Investment funds are an important part of the capital market. Household savings in this type of asset are increasing every year. From an investor’s point of view, the performance of funds is important. These, along with the risks, are what most often determine the choice of fund type and finally the specific fund. The performance of a fund is often determined by both the size of the fund and the application of the managers’ selectivity and market sense.

Purpose

The aim of this research is to investigate the impact of fund size on performance through the use of selectivity and market sense by managers. Dividing funds into size groups will allow the search for patterns in terms of managers’ use of market timing.

Research methodology

The research used a Treynor-Mazuy model as a market timing model and Ward’s method as the cluster analysis methods. The performance of the funds was determined using an investment performance indicator, i.e., Omega.

Results

The obtained results indicate that the funds are similar within the groups. However, there were differences in the results between the groups. During periods of high volatility, it is recommended to invest in units of funds with an average size below the median.

Novelty

The added value is the study of market timing in groups of funds similar in size. In each group, the results of the Treynor-Mazuy model estimation, and the Omega investment efficiency index were determined, and the differences in the obtained results between the groups were examined. Finally, all funds were clustered using the Ward method.

Published: December 2024

Ethnic, linguistic identity, heritage language maintenance and transmission, language attitudes and policies remain important topics in nowadays globalized world. The main purpose of this study, which is a part of a large-scale research on Lithuanian heritage language, was to analyze the linguistic and ethnic identity development within Lithuanian diaspora. The article investigates the linguistic attitudes, language practices and language policies within the Lithuanian diaspora in Ireland and Norway, paying extra attention to the younger (K2) generation of Lithuanian migrants. A specialized sociolinguistic questionnaire was developed for this study. A total of 74 first-generation Lithuanian emigrants based in Ireland (n = 18) and Norway (n = 56) participated in the online survey. All participants had children aged 4–17. The data from the questionnaire survey are also illustrated with examples from 5 semi-structured interviews. The study revealed that emigrants from both countries maintain a strong connection with their country of origin. Almost half of the respondents claim that their children visit Lithuania at least once a year, while more than a third of respondents’ children visit Lithuania twice a year or more often. A third of participants are planning to return to Lithuania. Most of the respondents enroll their children to Lithuanian Saturday schools. However, the younger generation seem to differ from their parents in their language attitudes and practices: Lithuanian children based in Ireland tend to feel a stronger connection with the majority language (English) than Lithuanian. Meanwhile, children in Norway are multilinguals, having more than two languages in their everyday repertoire. To summarize, the study demonstrated the main language attitudes and practices of Lithuanians abroad and also highlighted some differences between the first and the second generation of Lithuanian migrants. The results from this study might provide interesting insights for future studies in the fields of sociology, sociolinguistics, and diaspora studies.
