The Concept of Ensuring the Strong Sustainability of Ukraine's Electric Power Industry in the Conditions of Terrorist and Military Threats
Authors:   G.E. Pukhov Institute for Modelling in Energy Engineering National Academy of Sciences of Ukraine, Kyiv, Saukh S.Ye.
Published: July 2023

To support the strong sustainability of the energy sector in the conditions of terrorist and military threats, the concept of structural variability of the electric power industry is proposed. Structural variability is defined as the power system's ability to form such a number of subsystems and electrical connections between them that enables the operator to control the structure of the system and, in this way, ensure the hard stability of the power sector in conditions of purposeful destructive actions. We proposed a model of distributed market management of a structurally variable electric power system. The model is based on the decomposition of a single liberalized market into an upper-level market and regional markets interacting with each other according to uniform rules.

Published: July 2023

Este artículo tiene como objetivo presentar las percepciones sobre el efecto de las condiciones de trabajo en la salud y la labor profesional, que tiene el cuerpo docente de un centro público de educación técnico profesional, perteneciente a la Dirección General de Educación Técnico Profesional (DGETP) de Montevideo, Uruguay. Se ha indagado, específicamente, sobre las formas de trabajo durante la pandemia por la COVID-19 y cómo las condiciones de enseñanza remota de emergencia incidieron en la labor docente y la salud socioemocional. El diseño se basa en la metodología mixta de tipo convergente y se combinan datos provenientes de una encuesta aplicada a 171 docentes y otra realizada a 12 miembros del cuerpo docente del centro, entre noviembre y diciembre de 2021. Acerca de los resultados, estos indican que el desarrollo de las distintas actividades administrativas, así como los problemas de comunicación entre docentes y el equipo de gestión del centro corresponden a los principales factores estresores declarados por los y las docentes participantes. Con relación a las situaciones laborales surgidas en pandemia, las dificultades relacionadas con la conexión a internet y el estado de los dispositivos del estudiantado y la falta de apoyo desde la dirección e inspecciones fueron identificados como situaciones que han influido en la salud del cuerpo docente, provocando sentimientos de sobrecarga de trabajo, cansancio, estrés, desborde y angustia. Como recomendaciones, surge la necesidad de evaluar cómo el sistema educativo, en su generalidad, puede fortalecer las habilidades socioemocionales del profesorado en servicio y crear apoyos para atender aspectos relacionados al acompañamiento pedagógico-didáctico brindado por direcciones e inspecciones, con énfasis en las competencias digitales docentes.

The publication deals with the importance and function of inscriptions in residential homes in the upper layer from around 400 BC to AD 600. It investigates commonalities, differences and the development of the use of text in residential homes. The inscriptions are found on architectural components such as façades, door frames and pillars, as well as featuring in mosaics and wall paintings and on sculptures. In wall paintings we find both dipinti and spontaneous graffiti, including drawings. Most of the inscriptions can be assigned to adults, especially men. Female authors are present, but to a much smaller extent. The texts mention members of the household from all levels, referencing freedmen and slaves as well as visitors and guests. The inscriptions include, among other things, greetings and wishes on the part of those living in the house (especially those in mosaics) as well as apotropaic inscriptions to protect the house and its inhabitants, dedications (on altars and statues of deities) and praise of the head of the household (on sculptures portraying them). In many cases the graffiti were expressions of emotions. Explanatory texts were often added to figurative depictions on mosaic floors and frescoes; sometimes the sculptors or mosaicists have added their signatures. The inscriptions are located on the façades of houses and in the well-furnished and decorated living rooms, but some are also found in the latrines. The height at which they were located and the size of the inscription were generally chosen such that they could be easily seen and read.
Acquired non-incarcerated inguinal/scrotal herniation in working donkeys (Equus asinus)
Authors: Marzok M. A. , Moustafa A. M.
Published: July 2023

In equine practice, inguinal hernia is a common disease and can be either acquired (direct) or congenital (indirect). This retrospective study aimed to describe the presentation and surgical management of acquired inguinal/scrotal herniation in 11 working donkeys (nine intact males, one gelding, and one female). All donkeys had a unilateral acquired inguinal/scrotal hernia, which was noticed by the owner for a period of two to 24 weeks. All the swellings were reducible, painless, not accompanied by an acute abdomen. Ultrasonography, rectal, and clinical examination are useful tools for the diagnosis of inguinal/scrotal hernias in donkeys. Eight animals underwent successful inguinal herniorrhaphy with the removal of the testicle at the affected side, and the superficial inguinal ring was closed by application double-layer polypropylene mesh. The recovery period ranged from 14 to 25 days (average, 16.8 ± 2.8 days). All donkeys released from the clinic returned to their previous levels of exercise. Our study showed that acquired inguinal or scrotal herniation in donkeys is not a clinical emergency requiring prompt intervention. To the best of our knowledge, this is the first report describing this condition in donkeys.

Published: July 2023

The study compared the cardiorespiratory and anaesthetic effects of alfaxalone or propofol for total intravenous anaesthesia (TIVA) in dogs premedicated with acepromazine-buprenorphine. Six adult Nigerian dogs with mean±S.D. body weight of 11.5±1.6 kg were studied. Acepromazine hydrochloride (0.03 mg/kg) and buprenorphine (0.02 mg/kg) were mixed in the same syringe and administered intramuscularly as premedicants. Following obvious sedation, anaesthesia was induced with bolus intravenous (IV) injection of either 2.0 mg/kg alfaxalone or 4.0 mg/kg propofol over a period of about 30 s. Repeated IV bolus injection of either 1.0 mg/kg alfaxalone or 2.0 mg/kg propofol was administered at 10 minute interval for maintenance of anaesthesia over 90 minutes. Physiological variables were measured and recorded at 15 minute intervals over 90 minutes using a multi-parameter monitor. Onset and duration of analgesia with alfaxalone protocol (2.2±0.4 min and 106.2±4.0 min) were significantly (P<0.05) shorter than those with propofol protocol (4.5±1.4 min and 124.5±3.4 min) respectively. Duration of recumbency with alfaxalone (159.5±18.9 min) and propofol (150.8±5.7 min) were not significantly different. Time to standing and recovery time with alfaxalone (38.2±10.8 min and 76.8±28.4 min) were significantly (P<0.05) longer than those with propofol (14.0±3.8 min and 23.5±6.4 min respectively). There were no significant differences between mean heart rate (HR), mean arterial pressure (MAP), respiratory rate (RR), haemoglobin oxygen saturation (SpO2) and rectal temperature (RT) between both protocols. In conclusion, either alfaxalone or propofol appeared to be equally efficacious and safe for induction and maintenance of anaesthesia in healthy dogs premedicated with acepromazine-buprenorphine.

Published: July 2023

The present study aimed to explore the virulence characteristics in 221 Bulgarian nosocomial Stenotrophomonas maltophilia isolates (2011–2022) via screening for the presence of virulence genes, their mutational variability, and the corresponding enzyme activity. PCR amplification, enzymatic assays, whole-genome sequencing (WGS), and biofilm quantification on a polystyrene plate were performed. The incidence of virulence determinants was as follows: stmPr1 (encoding for the major extracellular protease StmPr1) 87.3%, stmPr2 (minor extracellular protease StmPr2) 99.1%, Smlt3773 locus (outer membrane esterase) 98.2%, plcN1 (non-hemolytic phospholipase C) 99.1%, and smf-1 (type-1 fimbriae, biofilm-related gene) 96.4%. The 1621-bp allele of stmPr1 was most frequently found (61.1%), followed by the combined allelic variant (17.6%), stmPr1-negative genotype (12.7%), and 868-bp allele (8.6%). Protease, esterase, and lecithinase activity was observed in 95%, 98.2%, and 17.2% of the isolates, respectively. The WGS-subjected isolates (n = 9) formed two groups. Five isolates possessed only the 1621-bp variant of stmPr1, higher biofilm formation ability (Optical Density at λ = 550 nm (OD550): 1.253–1.789), as well as a low number of mutations in the protease genes and smf-1. Three other isolates had only the 868-bp variant, weaker biofilm production (OD550: 0.788–1.108), and higher number of mutations within these genes. The only weak biofilm producer (OD550 = 0.177) had no stmPr1 alleles. In conclusion, the similar PCR detection rates did not allow differentiation of the isolates. In contrast, WGS permitted stmPr1 alleles-based differentiation. To the best of our knowledge, this is the first Bulgarian study presenting genotypic and phenotypic insights into virulence factors of S. maltophilia isolates.
Raden Saleh dan Restorasi Makam Tahun 1953: Penghormatan Pelukis Bumiputera dan Penguatan Identitas Nasional pada Masa Kekuasaan Soekarno

Published: July 2023

Raden Saleh, the first painter in Java to adopt modern techniques and gain recognition in the Western world during the Dutch colonial era, holds an important place in Indonesian art history. This article examines the life and contributions of Raden Saleh. It explores the restoration of his tomb by President Soekarno as a means to strengthen Indonesia's national identity in the post-independence period. The research utilizes historical methods, including heuristics, source criticism, interpretation, and historiography. The study reveals that the restoration of Raden Saleh's tomb in 1953, under President Soekarno's leadership, aimed to pay homage to Raden Saleh as a prominent figure in Indonesian history and reinforce the Indonesian identity by recognizing the globally renowned indigenous elite. Although Raden Saleh passed away long before Indonesia's independence, and the concept of Indonesia as a nation emerged much later, the government, particularly under President Soekarno and Minister of Education and Culture Mohammad Yamin, believed that the restoration was necessary due to the unsatisfactory condition of the tomb. Additionally, the presence of paintings reflecting indigenous perspectives and occasionally criticizing colonialism influenced the decision to restore the tomb. This research sheds light on the significance of Raden Saleh's legacy in shaping Indonesian art and the efforts to preserve cultural heritage in the nation. Keywords: Culture, Raden Saleh, Restoration, Soekarno

Published: July 2023

The aim with this study was to analyse and explore how physical sciences, engineering science and technology subjects (technical electrical technology, technical civil technology, technical mechanical technology) can contribute to the alignment of the technical sciences curriculum. We used document analysis to collect data. An analysis of the curriculum and assessment policy statements (CAPS) for technical sciences, physical sciences, electrical technology, civil technology, mechanical technology, and textbooks for engineering science was done. The findings of the study suggest that the technical science curriculum is a replica of the physical science curriculum. We recommend that the technical sciences curriculum be reviewed such that relevant scientific concepts can be used to bridge the gaps identified in the curriculum. The implications are that a new, aligned technical sciences curriculum that is relevant for technology subjects must be developed.

Published: July 2023

ABSTRACT Introduction: Brazil has a vast territory divided into five geographic regions with important differences in sociodemographic indices. We aimed to present and compare socio-demographic characteristics, biochemical results, and drug prescription of patients on chronic hemodialysis (HD) treatment in the five geographic regions. Methods: We evaluated data from the Brazilian Dialysis Registry of all adult patients undergoing chronic HD in 2021. Variables included sociodemographic characteristics, serum levels of phosphate, calcium, and albumin, hemoglobin, urea reduction rate, and prescription of phosphate binders, erythropoietin, and intravenous iron. Data from the North and Northeast regions were combined into one group. Results: A total of 13,792 patients (57.9 ± 16.0 years old, 58.5% male, median HD vintage of 31 (11–66) months) from 73 dialysis centers were analyzed. Regional distribution was 59.5% in the Southeast; 21.7% in the South; 5.9% in the Midwest; and 12.9% in the North/Northeast. Sociodemographic features, biochemical results, and medication prescriptions differed across regions. The prevalence of elderly patients was lower in the Midwest and North/Northeast. The South region had the highest prevalence of hyperphosphatemia (41.2%) and urea reduction rate <65% (24.8%), while anemia and hypoalbuminemia were more prevalent in the Southeast, 32.7% and 11.6%, respectively. Conclusion: We found differences in socio-demographics, clinical features, and drug prescriptions across Brazilian geographic regions. Some findings reflect the socio-demographic diversity of the country, while others deserve further elucidation.
Trends in CSF Leakage Associated with Duraplasty in Infratentorial Procedures over the Last 20 Years: A Systematic Review
Authors: Achinger Katherine G. , Williams Lakiesha N.
Published: July 2023

Cerebrospinal fluid (CSF) leakage is a common postoperative complication of neurosurgical procedures, with iatrogenic causes accounting for 16% of CSF leakages. This complication increases healthcare costs and patient morbidity. The focus of this review is to analyze the rates of CSF leakage of some of the most commonly used xenogeneic and synthetic dural substitutes following surgeries in the infratentorial region of the brain where surgical repair can be most challenging. A systematic literature search was conducted using studies detailing duraplasty procedures performed with nonautologous grafts in the infratentorial region in PubMed. Studies were identified using the following search terms: "posterior fossa" or "infratentorial" were used in combination with "CSF leak," "CSF leakage," "cerebrospinal fluid leakage," "duraplasty" or "dura graft." The outcome of interest was a measure of the prevalence of CSF leakage rates following posterior fossa neurosurgery. Studies that contributed data to this review were published between 2006 and 2021. The dural graft materials utilized included: bovine collagen, acellular dermis, equine collagen, bovine pericardium, collagen matrix, and expanded polytetrafluoroethylene (ePTFE). The number of subjects in studies on each of these grafts ranged from 6 to 225. CSF leak rates ranged from 0% to 25% with the predominance of studies reporting between 3% and 15%. The studies that utilize bovine collagen, equine collagen, and acellular dermis reported higher CSF leakage rates; whereas studies that utilized ePTFE, bovine pericardium, and collagen matrix reported lower CSF leakage rates. Due to the heterogeneity of methodologies used across these studies, it is difficult to draw a direct correlation between the dural patch products used and CSF leaks. Larger prospective controlled studies that evaluate various products in a head-to-head fashion, using the same methods and animal models, are needed to conclude the relative efficacy of these dural patch products.

Published: July 2023

Typical solid rocket motor exhaust emissions consist of high temperature gaseous pollutants including hydrochloric acid, chlorine, and alumina particles. A scrubber is developed to treat the gaseous and particle pollutants present-reducing the detrimental impact of such testing on the environment. A series of water spray configurations are studied to cool the plume without alumina particle modelling. A system consisting of two jets oriented at 60 degrees offers the best performance without compromising safety; the exhaust gases are cooled from over 3000 K to ambient over a distance of 1 meter from the nozzle exit.

Published: July 2023

Liquefaction technologies of natural gas using a mixed refrigerant cycle provide a high liquefaction coefficient at low specific energy consumption, but are characterized by high requirements for the organization of production. There is no methodology for simultaneous optimization of the technical and economic parameters for the production process of liquefied natural gas and the composition of the refrigerant in publications, and therefore a combined optimization criterion is needed to achieve the minimum cost of liquefied natural gas. The aim of the work is to determine optimal pressure for natural gas inlet compression, taking into account the minimization of the complex criterion – the conditionally variable part of the cost of liquefied natural gas. The results were obtained using an applied calculation program, and the method of differential evolution was chosen as an optimization method. The optimization was carried out using the OCMR PEGAZ 1.0 program. The article considers the influence of the discharge pressure of the low-pressure natural gas inlet compressor on the technical characteristics of heat exchange equipment, the energy efficiency of the liquefaction process and the economic characteristics of a low-tonnage liquefied natural gas production plant under conditions of optimized composition and flow rate of mixed refrigerant. A method of optimizing process parameters taking into account economic indicators is proposed, regularities of changes in the optimal composition of mixed refrigerant depending on the discharge pressure of the natural gas inlet compressor are determined. It is determined that with an increase in the discharge pressure of the natural gas inlet compressor, the optimal content of components in the mixed refrigerant changes as follows: methane and n-pentane decrease, and ethane and isobutane increase. It is shown that the optimal discharge pressure range of the natural gas inlet compressor is 6,0±0,5 MPag, which leads to the best total energy efficiency of inlet compression and circulation of mixed refrigerant, equal to 0,25 kWh/kg of LNG, and its cost is minimal. The assessment of capital costs at this pressure will allow choosing the optimal technology of natural gas liquefaction at the FEED stage, which will reduce the cost of production of liquefied natural gas and reduce the payback period to 5 years.

Published: July 2023

The article presents the results of a study of hydrocatalytic processing of two fuel oils in the presence of nanocatalytic systems in the form of oil-soluble precursors based on nickel and zinc. The process was carried out on a pilot plant for hydroprocessing with a flow reactor at a temperature of 440 ℃, a hydrogen pressure of 6 MPa, a feed space velocity of 1.0 s-1, and a hydrogen circulation ratio of 1000 nl/l. The catalyst efficiency was evaluated by changes in the material balance, in hydrogenate desulfurization degree, in 450+ °C fraction conversion degree, and by changes in density and hydrogenate refractive index. An analysis of material balances showed that the addition of nanocatalyst precursors increases the 180–350 °C fraction yield, reduces the coke yield on the fixed layer, which is a layer of ceramic balls, and reduces the 450+ °C residual fraction yield. The gas and gasoline fraction yield is slightly reduced. The analysis of hydrogenates showed a decrease in sulfur content, a decrease in density and refractive index in hydrogenates obtained during the hydroprocessing of raw materials with the addition of nanocatalyst precursors. The optimal concentrations of catalysts were experimentally determined; for nickel, the concentration is 0.1 wt %, and for zinc is 0.15 wt %. A comparison of two methods for the synthesis of nanoscale catalytic systems in raw materials was made: directly in the reaction zone in situ and outside the reaction zone ex situ. The method for synthesizing nanoscale catalytic systems outside the reaction zone makes it possible to further increase the feedstock conversion, the hydrogenate desulfurization degree, and the hydrogenate quality.

The importance of returning production and consumption waste into circulation is obvious, both in terms of environmental safety and economic feasibility. The cyclicality of resources is one of the main elements of the concept of a circular economy, the expediency of which is generally recognized today. The processing of various waste fractions differs significantly in terms of energy saving and profitability relative to the production of primary material and the complexity of technological processes. Composting is a natural process of decomposition of organic matter. Compost has no phytotoxic and pathogenic properties, it is characterized by the presence of humic acids. Composting involves reducing the volume of waste, which allows solving environmental problems associated with the accumulation of waste, turning them into a safer product used as an organic fertilizer. Composts are used to increase crop productivity, increase soil fertility, add additional nutrients to the soil, increase plant growth, and suppress diseases caused by soil pathogen. Composting is one of the most effective methods for reducing the toxicity of biodegradable organic matter. The decrease in toxicity is associated with the decomposition of organic pollutants, the mineralization of the substrate, and processes that limit their availability.
La noción de niño en el Emilio: una lectura cruzada entre Rousseau y Deleuze
Authors: Galindo Olaya Juan Diego
Published: July 2023

Jean Jacques Rousseau nos propone pensar las situaciones en las que el niño es constituido y construye relaciones consigo mismo, con los otros y con las cosas. Nos preguntamos entonces: ¿cuál es la situación en la que han sido puestos los niños en nuestra cultura, que resulta contraria a su naturaleza? Los discursos pedagógicos que han asumido el postulado del niño como centro del proceso educativo no han abordado la razón sensible como concepto para pensar al niño y sus relaciones. Por tanto, reflexionamos a partir de una lectura cruzada con Gilles Deleuze sobre el niño en términos de su sensibilidad a los signos como primera forma de conocimiento de sí mismo, de los otros y la sociedad, la cual se ve limitada o potenciada por las relaciones en las que se le inscribe al nacer.
Decision-making skills and styles as predictors of managerial performance
Authors:   , Erceg Nikola
Published: July 2023

The aim of this multi-paper dissertation (i.e. Scandinavian model PhD thesis) was to address several of the gaps identified in the literature related to the assessment of individual differences in reasoning and decision-making quality, sometimes also referred to as rationality. In first two studies, we tested the construct validity of the cognitive reflection test (CRT) and its nonnumerical counterpart belief-bias syllogisms (BBS; Study 1) and investigated different ways and approaches to solving these tasks (Study 2). We concluded that CRT and another numerical test that does not contain lures are factorially indistinguishable and that lures do not play role in the success on or predictive validity of the CRT or BBS (Study 1). Additionally, we showed that in many cases when CRT and BBS tasks are solved correctly, they are solved relying solely on intuition and not analytical thinking. We conclude that these two tests are therefore not particularly good measure of reflection and analytical thinking engagement as thought before. In Study 3, across two studies, we examined a factorial structure of different cognitive biases tasks in a bid to understand the structure of rationality captured by these tasks and to validate identified rationality factor(s). In both studies, one-factor solution was the most appropriate and, to a large degree, explained by numerical abilities and thinking disposition called actively open-minded thinking (AOT; 61% of the rationality factor variance in Study 1 and 75% in Study 2). We conclude that cognitive biases tasks are highly heterogeneous and not particularly good solution for measuring rationality. Instead, we argue that individual differences in rational judgments and decisions matter are better captured by AOT. In Study 4, across three samples (undergraduates, employed participants and entrepreneurs), we showed that decision-making styles matter for various real-life and work-related outcomes, often adding explanatory power over cognitive abilities and personality traits. Finally, in Study 5, we examined the relevance of managerial AOT for positive organizational and employee-level outcomes. Over two studies, managers’ AOT correlated positively with range of positive personal and organizational outcomes. We concluded that concluded that it would be worthwhile to focus on AOT in selection for leadership positions as well as teach current leaders about the benefits and implementation of this way of thinking. In sum, results of our five studies point to the conclusion that how we think is as important, if not more, for consequential real-life outcomes, than how smart we are. What seem to be the most important is not to avoid decision-making and making them after the process of thinking in an actively open-minded way.

Foi identificado que antes da consulta 89 idosos (30,6%) faziam uso de MPI e que após a consulta com geriatra 110 idosos (37,6%) passaram a utilizá-los, sem diferença estatística. A mediana de números de medicamentos posteriores à consulta ambulatorial foi maior do que anterior à consulta, com significância estatística (p<0,001). Constatou-se que dos idosos que não recorriam à polifarmácia, 20,4% começaram a utilizá-la após a consulta. CONCLUSÃO: Mesmo após a consulta com o geriatra ainda existem inadequações nas prescrições, com um número relevante de idosos utilizando cinco ou mais medicamentos e em uso de MPI.

Erhebung des Stands der Notfallvorsorgeplanung in der Abwasserbeseitigung – Methodik und Status Quo in Rheinland-Pfalz
Authors: Broß Lisa , Euringer Christoph
Published: July 2023

Die Notfallvorsorgeplanung in der Abwasserbeseitigung umfasst neben präventiven Maßnahmen zur Risikominimierung insbesondere Aspekte des Notfall-/Krisenmanagements. Dieser Artikel zeigt eine Methodik, um den Stand der Notfallvorsorgeplanung vor Eintritt von Schadensereignissen beurteilen zu können. Der entwickelte Notfallvorsorgeplanungsindikator wurde im Rahmen der Benchmarking Initiative der Wasserwirtschaft in Rheinland-Pfalz erhoben. Die Ergebnisse zeigen, dass der Umsetzungsstand der Notfallvorsorgeplanung in Abwasserbeseitigungsunternehmen durch eingehende Betrachtung der Prozessschritte des Risiko- und Krisenmanagements ermittelt werden kann. Im Bereich der Vorplanung sowie den Vorbeugenden Maßnahmen sind einige Abwasserbeseitigungsunternehmen bereits gut aufgestellt. Handlungsbedarf besteht jedoch insbesondere in den Bereichen der Risikoanalyse und des Krisenmanagements. Zudem ist die regelmäßige Evaluierung der Prozessschritte verbesserungswürdig. Die Studie zeigt, dass Erhöhung der Resilienz von Abwasserbeseitigungssystemen vermehrt Aufmerksamkeit geschenkt werden und Möglichkeiten zur Finanzierung derartiger Maßnahmen verbessert werden sollten.

Authors: Pessanha Elisabete , Alexandre Joana , Maia Ângela
Published: July 2023

Este estudo propõe analisar o contributo da avaliação técnica na tomada de decisão judicial tutelar educativa nas fases pré e pós sentenciais. Para o efeito, foram consultados 30 processos judiciais tutelares educativos de 37 jovens com idades compreendidas entre os 12 e os 16 anos, tendo sido feita uma análise documental, com recurso à construção de uma grelha analítica. Os resultados indicam que os magistrados concordam com 93,3% das medidas tutelares sugeridas pelos técnicos/psicólogos forenses. Quando há revisão de uma medida tutelar, observa-se uma correspondência entre as sugestões técnicas e a aplicação de medidas judiciais em 87,5% dos casos. Relativamente à frequência de interações entre técnicos e magistrados no período pós-sentencial, esta ronda os 73,3%. Estes resultados sugerem uma cooperação consistente entre magistrados e técnicos sociais durante todo o processo, assim como uma ampla valorização do trabalho e das propostas dos técnicos sociais.
The Pattern Language Approach as a Bridge Connecting Formal and Informal Urban Planning Practices in Africa
Authors: Namwanje Priscilla , Muñoz Sanz Víctor , Rocco Roberto
Published: July 2023

This article explores the use of the pattern language approach in bridging the gap between formal and informal urban planning practices in the African context. This study focuses on a case application within the urbanised region encompassing the Nakivubo wetland located in Kampala, Uganda. As in other cities in Africa with a colonial past, Kampala’s planning system signals a profound gap between a technocratic, European paradigms-based type of planning and the everyday practices of citizens. This results in a “dual city,” with formal and informal communities using resources and spaces differently, leading to spatial segregation and non-implementation of urban plans. To overcome this challenge, the pattern language approach is utilised in this research to link formal and informal practices through facilitating meaningful community participation and integrating tacit knowledge into the planning process. To achieve this, the researchers conducted fieldwork and interacted with the local community in informal settlements to develop informal patterns, while analysing the history and current organisation of formal planning institutions in Kampala to formulate formal patterns. The patterns were used as input for a community workshop, which resulted in a pattern language of wetland management practices and a framework that begins to bridge both formal and informal domains of urban practice. By using the pattern language approach as a tool to understand informal practices and their possible incorporation into a planning process that captures the needs of citizens, this research offers relevant insights into achieving sustainable and inclusive urban environments.
Reflecting on eclecticism in garden heritage: The Monforte Gardens in Valencia as a case study
Authors: Marcos Carlos L. , Gómez-Gil Antonio , García-Doménech Sergio
Published: July 2023

Precedent historic styles were analysed and recovered by historicist revisionism and revivalism during the nineteenth century. The lack of a style of its century lead to eclecticism, a trend that involved a merging of diverse ornamental repertories. Accordingly, eclectic garden design employed historic styles of different origins. As the cities grew, suburban gardens were integrated within the urban sprawl. The Monforte Gardens in Valencia represent a relevant case study characteristic of nineteenth century major garden design and development transformations. Most significant are the design resources and strategies introduced in the original design by Sebastián Monléon and, subsequently by Javier de Winthuysen as this research —including a thorough redrawing of the garden layout— gives evidence of. The Monforte Gardens represent an eclectic urban gardening design example in which the different parts maintain their independence without losing an overall unitary concept. Although traditionally considered neoclassical gardens, this research argues they should be properly considered as eclectic romantic gardens.
Traer al mundo el mundo: cartografías de Alighiero Boetti
Authors: Mancebo Roca Juan Agustín
Published: July 2023

La serie Mappe constituye una de las obras icónicas de Alighiero Boetti. Iniciada durante su segundo viaje a Afganistán, fue un trabajo cooperativo en el que las piezas fueron proyectadas por el artista y bordadas por mujeres afganas. Este artículo analiza el proceso conceptual y creativo de los mapas de Boetti, un trabajo progresivo que supuso la concreción de los procesos cartográficos iniciados en 1967 sobre planos de ciudad y mapas de espacios de conflicto. Los Mappe se convirtieron en un elemento nodal en su trabajo con aproximadamente ciento ochenta piezas que enlazarían con su última producción, configurando un conjunto en el que las obras se resignifican individualizando la diversidad del mundo. Los mapas, además, supusieron la transcripción de un espacio mental que contendría la representación de la totalidad del mundo y que solo eran capaces de develarse en su contemplación.
La estética de la ruina en el videojuego. Rúbricas históricas y metáforas visuales para el espacio ludonarrativo
Authors: Castiñeiras López Javier
Published: July 2023

En el presente artículo se abordará el estudio de las ruinas en el videojuego, entendidas estas como parte de un constructo cultural más amplio por el que la ruina en la cultura occidental pasa de ser un vestigio físico para convertirse en un escenario para la evocación connotativa. Para ello se repasará sucintamente el proceso de resemantización que la ruina ha adquirido a partir de la literatura y las artes visuales, para posteriormente ahondar en algunos ejemplos del videojuego, siguiendo una estructura en tres puntos: la ruina arqueológica, el mito neomedieval y la ciudad contemporánea.

Adriatic Sea as a part of the Mediterranean is settled by many introduced species which extend their range northward. Among them is the rayed pearl oyster Pinctada radiata, a mollusk of Indo-Pacific origin that colonises habitats throughout the Mediterranean. P. radiata established a population in a fish farm on the island of Mljet in the Adriatic Sea, which was observed in 2017. To determine the status of the population, 48 specimens of P. radiata were randomly sampled from the ropes of a fish farm in 2019. Morphometric parameters were determined using a digital calliper. The recorded parameters showed that shell height ranged from 50.55 mm to 72.98 mm, shell length from 46.66 mm to 71.15 mm, and shell width from 19.98 mm to 58.54 mm. During additional visual survey in 2020 the presence of the spat within population at Mljet fish farm was not observed. It appears that only adult specimens are present, and it is unclear if the population is reproducing. In addition, P. radiata spat was observed in the shallow waters of Lokrum Island in 2021 and 2022, indicating the possibility of survival of larvae naturally dispersing from pre-existing populations. An adult specimen of P. radiata was also observed in Mali Ston Bay on two occasions, in 2009 and 2021. P. radiata, a highly adaptable species that tolerates a wide range of environmental factors, has successfully colonised new habitats.
