Authors: Armas Juan Carlos , Lapido Rodríguez Margarita , Gómez Julio Rafael , Valdivia Nodal Yarelis
Published: November 2022

An analysis of a chilled water central air conditioning system is presented. The object was to calculate main cycle component irreversibility, as well as evaluating this indicator' s sensitivity to operational variations. Artificial neural networks (ANN), genetic algorithms (GA) and Matlab tools were used to calculate refrigerant thermodynamic properties during each cycle stage. These tools interacted with equations describing the system's thermodynamic behaviour. Refrigerant temperature, when released from the compressor, was determined by a hybrid model combining the neural model with a simple genetic algorithm used as optimisation tool; the cycle' s components which were most sensitive to changes in working conditions were identified. It was concluded that the compressor, evaporator and expansion mechanism (in that order) represented significant energy losses reaching 85.62% of total system irreversibility. A very useful tool was thus developed for evaluating these systems.

Published: November 2022

The embankment model has been developed in laboratory conditions, considering actual embankment characteristics. The forces to which it is subjected in the model have been evaluated using shaking table experimental and analytical methods. Excess pore water pressure is measured through pore pressure sensors in the shaking table experiment and embankment stability has been assessed using analytical methods. The results revealed that the embankment suffered nonlinear collapse during increasing pore water pressure, and shaking table dynamic force on the embankment model was very sensitive but was open to failure mitigation. Embankment seismic simulation using shaking table experiments helped identify model stability. The embankment and subsoil pore water pressure theoretical and experimental analysis concluded that nonlinear liquefaction characteristics played a major role in model behaviour.
Altitud y su relación con la incidencia, letalidad y mortalidad por COVID-19 en Perú: 2020-2021
Authors: Chilipio Chiclla Marco Antonio , Campos Correa Karen
Published: November 2022

Introducción. La incidencia, letalidad y mortalidad COVID-19 no ha sido igual en las regiones del Perú, situación que puede estar relacionada con factores pocos estudiados como la altitud; asimismo, características ambientales propias de la altura (presión atmosférica, humedad relativa, etc.) podrían explicar la dinámica de transmisión de la COVID-19.
Objetivo. Determinar la relación entre altitud e incidencia, letalidad y mortalidad por COVID-19 en Perú.
Materiales y método. Estudio ecológico de grupos múltiples. Se realizó un análisis secundario de datos oficiales COVID-19 de 1874 distritos del Perú reportados hasta febrero de 2021. La variable altitud se categorizó como baja (0-999 msnm), media (1000-2499 msnm) y elevada (≥2500 msnm). Las tasas de incidencia acumulada, letalidad y mortalidad por COVID-19 se calcularon como el número de casos entre la población total de cada distrito multiplicada por 10000, el número de defunciones entre el número de casos multiplicado por 100, y el número de defunciones entre la población total de cada distrito multiplicado por 100000, respectivamente. Para el análisis de los datos se empleó estadística bivariada (coeficiente de correlación de Spearman y prueba de Kruskal-Wallis) y multivariada (regresión lineal múltiple), con un nivel de confianza del 95%.
Resultados. Se observó una correlación inversa entre la tasa de incidencia acumulada (1823 distritos) y altitud (Rho:-0.355; p<0.001), es decir, se redujo a mayor altitud, y una correlación directa entre la tasa de letalidad (1526 distritos) y altitud (Rho: 0.131; p<0.001), es decir, aumentó a mayor altitud. Aunque la tasa de mortalidad mostró una correlación inversa con la altitud (Rho:-0.310; p<0.000), esta varía heterogéneamente según niveles altitudinales. En el análisis multivariado, luego de ajustar el modelo por pobreza y densidad poblacional, la altitud se asoció con las tasas de incidencia (p<0.001) y de letalidad (p=0.009), pero no con la de mortalidad (p=0.179).
Conclusión. Se observó una correlación inversa entre altitud y la tasa de incidencia de COVID-19 y una correlación directa entre altitud y la tasa de letalidad en Perú durante el periodo de estudio. Finalmente, no se encontró una correlación entre altitud y tasa de mortalidad.
A Remark on Nefness of Divisors on Surfaces of General Type
Authors: Bhattacharya Debojyoti , Das Joyentanuj
Published: November 2022

Let X be an irreducible complex projective variety of dimension n ≥ 1. Let D be a Cartier divisor on X such that Hi(X, OX (mD)) = 0 for m > 0 and for all i > 0, then it is not true in general that D is a nef divisor (cf. [4]). Also, in general, effective divisors on smooth surfaces are not necessarily nef (they are nef provided they are semiample). In this article, we show that, if X is a smooth surface of general type and C is a smooth hyperplane section of it, then for any non-zero effective divisor D on X satisfying H1(X, OX (mD)) = 0 for all m > C.KX, D is a nef divisor.

A HYBRID PSO-SA SCHEME FOR IMPROVING ACCURACY OF FUZZY TIME SERIES FORECASTING MODELS
Authors: Phong Pham Dinh , Duc Du Nguyen , Hoang Hiep Pham , Thanh Tran Xuan
Published: November 2022

Forecasting methods based on fuzzy time series have been examined intensively during last years. Three main factors which affect the accuracy of those forecasting methods are length of intervals, the way of establishing fuzzy logical relationship groups, and defuzzification techniques. Many researches focus on optimizing length of intervals in order to improve forecasting accuracies by utilizing various optimization techniques. In the line of that research trend, in this paper, a hybrid particle swarm optimization combined with simulated annealing (PSO-SA) algorithm is proposed to optimize length of intervals to improve forecasting accuracies. The experimental results in comparison with the existing forecasting models show that the proposed forecasting model is an effective forecasting model.

Published: November 2022

Flipped classroom is a pedagogical model that employs video, reading assignments, practice problems, and other digital technology-based resources outside the classroom to introduce the concept for more meaningful learning. In the Bhutanese education system, the conflict between limited availability of time and coverage of large volumes of syllabus material has become a central issue in curriculum design. Therefore, this study explored how flipped classrooms could be mediated to free up of classroom instructional hours without affecting student learning. This study also assessed students’ attitudes towards flipped classroom strategy. A total of 83 students participated in this study. A pre-test and post-test experimental research design for classroom instructional hours and survey questionnaire were employed to study students’ attitude towards flipped classroom strategy. SPSS was used for statistical analysis of the data on attitude rating and pre-test and post[1]test difference. Key findings include flipped classroom saved an average of up to 13.29% of instructional hours without affecting students’ learning. The difference of pre-test and post-test mean score for learning between the experimental and control group is not significant (p>.05, t=0.394). However, with a mean score of 4.60 on a five scale Likert scale for positive statements and a mean score of 1.49 for negative statements, students have positive attitude towards flipped classroom.

Migrant Portraiture and Life Imaging in Fazal Sheikh’s Photodocumentaries
Authors: Mersmann Birgit
Published: November 2022

This article explores the role of migrant photo portraiture for life imaging by providing a close reading of two photobooks by contemporary photographer Fazal Sheikh – A Sense of Common Ground (1996) and The Victor Weeps. Afghanistan (1998). Visual storytelling is a core feature of this social and humanitarian photographer’s work, through which two main questions are addressed: how are real-life migration experiences as survival stories and personal biographies inscribed in the portraits of refugees and migrants? Which form(at)s of portraits are chosen, and which practices of portrayal are employed for the purpose of documenting migrant lives? Based on Jean-Luc Nancy’s portrait theory and Giorgio Agamben’s notion of ‘bare life’, the author introduces a process-analytical category of the ‘migrant/refugee portrait’ in order to grasp the complex (de-)figuration processes connected with the sociopolitical issues of human displacement. In Sheikh’s long-term portrayal of migrant/refugee communities and his concept of relational portraiture, she recognizes an effective documentary photo practice for de-othering and demigrantizing the portrait of the migrant as a  stereotypical representation of the ‘other’.

Revisiting Paleoearthquakes with Numerical Modeling: A Case Study of the 1679 Sanhe–Pinggu Earthquake
Authors: Wang Zijia , Li Yilong , Wang Wenqiang , Zhang Wenqiang , Zhang Zhenguo
Published: November 2022

Investigating a paleoearthquake in a region can be used to study the seismicity of fault zones, and provides guidance for earthquake prevention and disaster reduction in nearby cities. However, the short of reliable records brings challenges to the assessment of the paleoearthquake disasters. With the development of computational seismology, we can study paleoearthquakes using numerical modeling based on limited data, to provide a reference for understanding the physical laws of historical earthquakes and earthquake relief in present society. Taking the 1679 M 8.0 Sanhe–Pinggu earthquake as an example, we built a dynamic model with good consistency between the surface slip and historical records, calculated the strong ground motion based on it, and obtained the intensity distribution that was consistent with the previous investigation. We found that the heterogeneous dip-slip distribution caused by the fault geometry change may be the reason that the fault scarp only remains about 10 km. In addition, the intensity of Tongzhou area in this earthquake may be as high as XI. In the future, it may be necessary to pay attention to strengthening earthquake prevention and disaster reduction in this area. Then, we estimated the number of deaths in the study area at that time, and the mathematical expectation was of about 74,968. During the systematic retrospective study of paleoearthquakes, as shown in this article, we can gain new understandings of the rupture process of paleoearthquakes and evaluate earthquake disasters more accurately.

An overview on fundamentals of immediate release drug delivery system
Authors: Bundela Yogita , Agrawal Dilip , Bhaduka Gaurav
Published: November 2022

Tablet is most popular among all dosage forms today because of its convenience, ease of administration, greater flexibility in dosage form design, ease of production, and low cost and non-invasive therapy. Formulation of tablets requires API along with excipients. Excipients include lubricants, diluents, binders, glidants, disintegrants, sweetening agents, flavoring agents, etc. Recent trends indicate that multi-particulate drug delivery systems are suitable for achieving extended-release oral formulation with a low risk of dose dumping, mixing flexibility to attain difference release patterns, and reproducible and short gastric residence time. Modern technology in immediate-release tablets, such as novel granulation techniques and electrostatic dry powder coating techniques, are prevalent nowadays. Recently, the immediate-release formulation has been similar to various sustained-release formulations that are currently readily attainable.

Published: November 2022

Background and Aims: Laparoscopic cholecystectomy has emerged as a gold standard technique for gall bladder stones. The aim of the present study was to compare the analgesic effect of intravenous (IV) vs intraperitoneal (IP) dexmedetomidine as an adjuvant to intraperitoneal (IP) bupivacaine in laparoscopy. Methods: A prospective, randomized, double blind, interventional study was conducted on 100 patients undergoing laparoscopic cholecystectomy where they were divided into following 2 groups: Group A: Patients received IV 1µg/kg dexmedetomidine diluted to 30 ml with normal saline over 10 min and 40 ml of 0.125% bupivacaine IP after removal of gall bladder. Group B: Patients received IV 30 ml of normal saline and 1µg/kg IP dexmedetomidine in 40 ml of 0.125% IP bupivacaine after removal of gall bladder. The primacy outcome was noted as a difference in mean duration for need of first rescue analgesia. The total consumption of analgesic in first 24hours was recorded and compared between the two groups. Results: Both the groups were comparable in terms of demographic profile and intraoperative hemodynamic parameters with no statistical difference. Comparison of time to first analgesic requirement between the two groups showed statistically significant results with unpaired t test The time of first rescue analgesia in Group A was 151.80 min ± 76.624. and in Group B was 94.80min ± 21.499. The total analgesic requirement in 24 hours in Group A was 136.64 ± 31.251 and in Group B was 144.12 ± 21.49. Conclusion: In our study we concluded that intravenous dexmetomidine provided superior analgesia as compared to intraperitoneal dexmetomidine when used as an adjuvant with Bupivacaine intraperitoneally.

Published: November 2022

Background: Laparoscopic cholecystectomy has emerged over the open cholecystectomy as gold standard for surgical treatment of symptomatic gall stones. Although pain after laparoscopic cholecystectomy is less intense, but many patients may experience considerable pain during first 24 hours in post-operative period. Intravenous (i.v.) use of dexmedetomidine in perioperative period lead to 90% decrease in the serum catecholamine levels, and further diminishing the haemodynamic response and sedating the patient and decrease analgesic requirements in the post-operative period. The efficacy of dexmedetomidine in providing hemodynamic stability during perioperative period and anesthesial recovery in patients undergoing laparoscopic cholecystectomy is studied. Methods: 60 patients of ASA grade I and II and of either sex (20–50 years) allocated in one of two parallel groups containing 30 patients each. In Group A- Dexmedetomidine (i.v.) bolus over 10min and continuous maintenance infusion 0.5µg/kg/h and in group B-0.9% normal saline i.v. bolus and continuous maintenance infusion was done. Parameters noted were heart rate, mean arterial pressure, oxygen saturation, post-operative pain were evaluated using VAS and analgesic requirement. Results: Both the groups were similar results in terms of age, sex, weight, ASA status, duration of surgery and hemodynamic parameters. SBP, DBP, MAP, SpCO2, EtCO2 values for both the groups were similar at all the intervals of time. No significant side effects were noted. Conclusion: Dexmedetomidine, pre-anaesthetic medication and its intraoperative infusion, further reducing the intraoperative anaesthetic requirement, sympathoadrenal response to intubation, maintains intraoperative cardiovascular stability, smooth extubation, sedation, and reduction in postoperative complications.

Calculations of the total energy of Fe-Pt nanoclusters, corresponding in the phase diagram to the compositions of FePt, FePt3 intermetallics and possessing either characteristic structures L10 and L12, respectively, or non-characteristic disordered structure A1, as well as various particle habits (cuboctahedra, icosahedra) are carried out by molecular dynamics for the first time. The dependences of cluster stability on their size and temperature are plotted, along with the schemes of temperature transformations of cluster morphology and the dependence of the melting points of the clusters with these structures and habits on their size. The size range (2–8 nm) corresponds to the sizes of particles observed by high-resolution electron microscopy. It is shown that the species play an essential part in the phase transformations proceeding under heating in the nanostructured system Fe-Pt and leading to the formation of nanocrystals with highly ordered L10 structure possessing giant coercivity are cubic nanoclusters with the ordered structures L10 and L12. With an increase in cluster size, their stability and melting points increase, tending to saturation of the dependencies within the size range above 10 nm. The least stable clusters are those of intermetallics with non-characteristic disordered structure A1 and icosahedral habit.

The effect of method preparation on the activity of Fe2O3-NiO/γ-Al2O3 catalyst was investigated in process decomposition of methane. Fe2O3-NiO/γ-Al2O3 catalyst was prepared by impregnation and solution combustion methods. The samples were characterized by X-ray phase analysis (XRD), temperature-programmed hydrogen reduction (TPR-H2), BET and Raman spectroscopy. It has been shown that the method of preparation plays an important role in regulating the textural and morphological properties of catalysts and provides a difference in their catalytic activity. The synthesis of the Fe2O3-NiO/γ-Al2O3 catalyst by the solution combustion method, in comparison with the capillary impregnation method, leads to the formation of a large amount of FeNi and FeAl2O4 solid solutions, which ensured good catalytic activity at high temperatures. The Fe2O3-NiO/γ-Al2O3 catalyst synthesized by the solution combustion method demonstrated good activity with a hydrogen yield of 52% within 150 min of the reaction without any deactivation. According to the results of Raman spectroscopy, graphene-like carbon was obtained on the surface of the catalysts. On the catalyst of Fe2O3-NiO/γ-Al2O3 (СI) synthesized by capillary impregnation, 4‒5 layer graphene on Fe2O3-NiO/γ-Al2O3 (SC)-6-7 layer graphene is formed.
Sustainable technology for the production of artisanal cassava starch
Authors: Rodríguez Salazar Arsenio José
Published: November 2022

Yucca starch (Manihot esculenta Crantz) plays several important roles in agroecological agriculture in the tropics. It is an inexpensive source of carbohydrates of high nutritional quality and easily accessible, if preserved and stored. The process of starch artisanal extraction is carried out in Latin America in a rudimentary and impractical way, with water and raw material wasted, which generates losses and ecological problems. This study shows how a prototype of a technological process (Matilda v1.0) for the artisan extraction of yucca starch was designed, built, and optimized. The optimization was performed using the response surface methodology, and the experimental design is a Box-Wilson 23 full factorial central composite, uniformly rotated and orthogonally blocked per day. Around 60 kg of starch for 200 kg yucca on a working day was obtained. The estimated starch yield was 31.83%, within a confidence interval of (30.24-32.97%) and a prediction interval of (27.98-35.23%). This yield was higher than that reported for conventional artisanal extraction. Water use was about 0.3 L kg-1 yucca, significantly lower than in artisanal productions. The process developed would generate a lower impact on the environment and would allow small producers to empower themselves with sustainable technologies.

Published: November 2022

Basella alba L. (Malabar spinach) is a non-conventional food plant (PANC) with high nutritional value and economic potential. Light is a critical factor in plant growth, acting directly on the photosynthetic process. The photoselective meshes combine the physical protection of plants with the selective filtering of solar radiation to promote physiological responses. This work evaluates the growth of B. alba under different light environments. The experiment occurred in a greenhouse at the Center for Agrarian, Environmental and Biological Sciences of the Federal University of Recôncavo da Bahia in a completely randomized design with plots comprising one useful plant and five replications. The plants were grown in three light environments: red ChromatiNet mesh, aluminet-thermo reflective mesh (both with 50% irradiance), and under full sun. The red mesh increased the root dry matter mass and stem diameter. The aluminet mesh increased the average number of leaves by about 50% compared to the plants cultivated under full sun. The results show that the cultivation of B. alba in different light environments promotes morphophysiological changes with positive increments in growth.

In the current years, silica nanoparticles have become more favorable in various disciplines like medicine, nano-biotechnology, the food industry, and drug delivery due to their tunable physicochemical characteristics. In this paper, the silica nanoparticles were synthesized by hydrolysis and condensation of tetra-ethyl-ortho-silicate (TEOS) in an ethanolic medium using ammonia as a stimulator in the reaction. The chemical bond structures of silica nanoparticles were analyzed by Fourier Transform Infrared Spectroscopy (FT-IR) which confirmed the existence of the Si-O bonds according to the different absorption peaks of the samples. The amorphous structure of these nanoparticles was certified by finding the board peaks in the X-Ray Diffraction (XRD) patterns. The elemental chemical composition of silica nanoparticles was investigated by Energy Dispersive X-Ray Spectroscopy (EDX) where 61.48wt % of silicon and 23.48wt% of oxygen were found. Almost round-shaped spherical and uniform silica nanoparticles with smooth surfaces were investigated by Scanning Electron Microscopy (SEM) measurement. The different particle sizes of silica nanoparticles within the range of 95±5.59 to 280±7.8 nm were found by controlling the concentration of TEOS. The optical absorption spectra and band gap calculations were also analyzed by Ultraviolet-Visible (UV-Vis) spectrophotometry for the different concentrations of TEOS. The results revealed that with increasing the concentration of TEOS, the absorption spectra of silica nanoparticles increased and their optical bandgap decreased from 3.92 eV to 3.79 eV.

Com aumento da expectativa de vida nos países em desenvolvimento as pessoas estão vivendo mais, e a busca pelo envelhecimento ativo tem sido alvo de diversas discussões na literatura. Dentre os diversos recursos disponíveis na fisioterapia podemos citar os exergames que consistem na utilização da interatividade para a realização de exercícios físicos, reproduzindo atividades funcionais associadas a fatores lúdicos, com a finalidade de treino e melhora do equilíbrio e aquisição da mobilidade. O objetivo desse estudo foi analisar os efeitos da intervenção com exergames no equilíbrio e mobilidade de idosos. A amostra foi composta por 18 participantes, submetidos à avaliação da mobilidade por meio do Timed Up and Go test e do equilíbrio por meio da Escala de Equilíbrio de Berg. O protocolo consistiu em oito semanas, com três sessões por semana, totalizando 24 atendimentos com duração total de 40 minutos. Após a intervenção, o score da Escala de Equilíbrio de Berg foi significativamente maior (54,5 ± 2,23) que o obtido na avaliação pré intervenção (49,15 ± 5,53). Sobre a mobilidade, houve redução significativa do tempo para a realização do Timed Up and Go test (9.6 ± 2.89) comparado a pré intervenção (12.25 ± 3.13). Pode-se concluir que uso dos exergames da plataforma Xbox 360 Kinect como intervenção promoveu melhora significativa nas variáveis equilíbrio e mobilidade nos idosos participantes.

Authors: Machado Rafaela Ribeiro , Santos Amanda Francielle
Published: November 2022

O controle da dor no recém-nascido é fundamental para uma melhor assistência, portanto sua mensuração é indispensável. Objetivo: Descrever através da literatura os principais métodos de avaliação da dor e as intervenções não farmacológicas utilizadas pela equipe de enfermagem no recém-nascido. Foi realizada uma pesquisa bibliográfica de artigos nacionais e oriundos da base de dados eletrônicas BVS durante o período de 2017 a março de 2018. Foram analisados 13 artigos ao todo. No presente estudo a equipe de enfermagem relatou em alguns artigos que usam os métodos não farmacológicos e a exemplo tem-se sucção não nutritiva com glicose ou não, mudança de decúbito, enrolamento, etc. Quanto a avaliação a dor ela foi avaliada de forma empírica sem a utilização de escalas de avaliação da dor padronizada em boa parte dos estudos. Poucos meios validados são utilizados para avaliar a dor neonatal.

Sensual Construction of Body and Biography. Suggestions to Mutually Improve Deficient but Widespread Body Concepts and Biographical Research
Authors: Fischer Wolfram
Published: November 2022

Against the backdrop of an increasing interest in visual methods in social research, this paper examines some theoretical foundations of human (inter-)action by reflecting on the interplay between senses, the body, and biography. The main purpose of the paper is to combine an integral, non-Cartesian concept of the self as body (respectively the lived body as self) with biographical research—thus enriching research on the body, as well as on biography. Criticizing the Cartesian split of body and mind, classical phenomenological (Leib) and recent concepts of the body (“embodiment”) are sketched, resulting in a processual model of the sensual construction of the lived and living body in its environment. Given the interplay of bodily foundations of the self and processes of biographical structuring, so far, distant fields of research are converged. Some suggestions for conceptual improvements, an attentional shift to body aspects, respective research topics, and the extension of methods exceeding the narrative biographical interview in biographical research are indicated.
The Social Transformation of Self-Injury
Authors: Adler Patricia A. , Adler Peter
Published: November 2022

This research offers a description and analysis of the relatively hidden practice of self-injury: cutting, burning, branding, and bone breaking. Drawing on over 150 in-depth interviews and tens of thousands of website postings, e-mail communications, and Internet groups, we challenge the psycho-medical depiction of this phenomenon and discuss ways that the contemporary sociological practice of self-injury has evolved to challenge images of the population, etiology, practice, and social meanings associated with this behavior. We conclude by suggesting that self-injury, for some, is in the process of undergoing a moral passage from the realm of medicalized to voluntarily chosen deviant behavior in which participants’ actions may be understood with a greater understanding of the sociological factors that contribute to the prevalence of these actions.

Background: Long term regular practice of soybean-chickpea and soybean-wheat system in the growing region is posing severe problems before the growers such as low productivity, profitability and monetary net return use efficiency due to delayed sowing of wheat and low market value of produce as well as poor economic viability of this cropping system. Methods: A field trial was laid out during monsoon (rainy), winter and late winter seasons of the year 2015-16 and 2016-17 to evaluate the productivity, cost benefit and sustainability of soybean based crop sequences under Vertisols for Malwa Plateau at the experimental field of Krishi Vigyan Kendra, Dhar, Madhya Pradesh in Central India. In 16 cropping sequences, soybean was sequenced with feasible winter crops viz. wheat, chickpea, garlic, onion, potato and garden pea with inclusion of garlic, onion in late winter and assessed in randomized block design with four replications. Results: Soybean (JS 93-05) - potato (Kufri jyoti) - onion (AFLR) cropping sequence registered the highest soybean equivalent yield (17731 kg/ha) with maximum gross returns (₹ 4,83,207/ha), net returns (₹ 3,62,170/ha), benefit: cost ratio (4.0) and monetary return use efficiency (per day return) (1156.01). Next highest soybean equivalent yield (10443 kg/ha) with maximum gross returns ₹ 2,83,337/ha, net returns ₹ 2,07,562/ha, benefit: cost ratio 3.74 and monetary return use efficiency (879.81) was recorded in soybean (JS 93-05) - onion (AFLR) cropping sequence than existing cropping sequences (soybean-wheat and soybean-chick pea).
Numerical modelling of primary bioproductivity of the Palaeozoic pelagic ecosystems
Authors: Zhuravlev Andrey
Published: November 2022

The article considers an approach to the reconstruction of the bioproductivity of Palaeozoic pelagic ecosystems based on the numeric modelling of the carbon isotope fractionation. The model uses information on the carbon dioxide content in atmosphere, water temperature, and carbon isotopic composition of carbonates and conodont elements. The developed model is tested on the material from the Upper Devonian — Lower Carboniferous of the northern Cis-Urals (successions of carbonate platform and slope of intrashelf depression). It allows reconstructing of the primary productivity of the Palaeozoic pelagic ecosystems and their dynamics on the basis of limited data. The results of the modelling are considered as rather qualitative than quantitative. The carbon isotope composition of total organic carbon was used for controlling the quality of the model.
Claves y documentos para un Virgilio posmoderno: los años ochenta del siglo XX en España
Authors: García Jurado Francisco
Published: November 2022

Los años ochenta del siglo XX miraron a Virgilio con una visión precisa y propia, inspirada por Nietzsche, y que podría definirse, básicamente, por la idea de la muerte (Broch), la enfermedad de la poesía (García Calvo), la conmemoración del bimilenario de su muerte (Colinas), su relectura poética en la clave de nuevas estéticas (Borges y Bernhard), el auge de la traducción en verso (Fontán Barreiro) y, finalmente, la relectura visual de su Eneida (Carlos Franco). Este trabajo se propone, mediante el análisis de una colección de los documentos que ilustran tales aspectos, dar cuenta de cómo el decenio de los años ochenta ha configurado una imagen particular de Virgilio.

Postępowanie odwoławcze w sprawie odwołania komornika sądowego w świetle ochrony prawa do sądu w sprawach cywilnych
Authors: Flaga-Gieruszyńska Kinga
Published: November 2022

W opracowaniu przedstawiono rozważania dotyczące ochrony prawa do sądu komorników sądowych odwołanych w drodze decyzji Ministra Sprawiedliwości w trybie art. 19 ustawy o komornikach sądowych. Autorka omawia przesłanki zmiany obecnie obowiązującej regulacji, zgodnie z którą decyzję o odwołaniu komornika sądowego zaskarża się do sądu administracyjnego, orzekającego co do zasady w oparciu kryterium legalności, co ogranicza zakres prowadzonego postępowania dowodowego. Z uwagi na „ekonomiczny” charakter skutków odwołania komornika sądowego, podobnie jak jest to przewidziane w odniesieniu do wydalenia ze służby na podstawie prawomocnego orzeczenia dyscyplinarnego, w tym przypadku powinien zostać wprowadzony również system zaskarżenia decyzji Ministra Sprawiedliwości do sądu powszechnego.
Planning acts as a legal form for ensuring solidarity in the local self-government
Authors: Mędrzycki Radosław
Published: November 2022

The principle of social solidarity is an essential element of a democratic state of law. Its legal expression affects public authorities, including the executive. In most European countries, public administration is obliged to follow and implement it. However, binding administration to the law — characteristic of modern democratic states — requires creating legal forms of ensuring this principle in regulations of a statutory rank.

The primary aim of this paper is to verify the hypothesis that planning acts in local self-governments may serve to ensure the realisation of the principle of social solidarity. Therefore, planning acts should be considered in the social policy of local authorities. Although the author has chosen the legal order of a specific European country (Poland) as a point of reference, the article’s conclusions are universal. The paper uses the dogmatic-legal and theoretical-legal research methods. The author also attempts to take into account the achievements of administrative policy science, including the particularly significant accomplishments of the Wrocław school.
