Authors: B. Bakare S.
Published: October 2021

ABSTRACT. In the present study, synthesis of a simple series of nitrogen heterocycles containing N-(p-bromophenyl) carboxamide moiety, such as benzimidazole, benzoxazine, oxadiazole and triazole compounds, by using 4-bromo aniline and diethyl oxalate as a key starting material has been described. Five nitrogen heterocycles compounds moiety were evaluated for their anticancer activity against MCF-7 cell line. The results revealed that compound 8 (N-(4-bromophenyl)-5-thioxo-1,3,4-oxadiazole-2-carboxamide) was the most potent cytotoxic activity. Cell cycle analysis demonstrated that compound 8 induce cell cycle arrest at G1 phase with apoptosis inducing activity marked by increase in G0 phase.

The Potocki family of the Pilawa coat of arms as the military leaders of Halych Land armed forces in the 17th century
In the 17th century the local parliaments of the Polish–Lithuanian Commonwealth were tasked with various military duties ranging from defensive capability matters, including self-defence of their own land or voivodeship, to the defence of the country borders. It often enough required raising the levy in great numbers or forming regular armed forces and appointing commanders of these troops. The article presents the actions such as appointing members of the local noble families as the commanders in chief that were undertaken by the dietines (sejmiki) of Halych Land in the 17th century. As it turns out, this leadership was most often granted to the members of the Potocki family, which resulted from a number of factors, among others, their long term settlement in this region, the local offices they held, their military expertise and last but not least, their significant wealth. The nobles who gathered during the local government sessions expected that the Potocki family would be able to fulfil duties imposed on them, and if needed they would support soldiers at their expense until the dietines reimbursed expenses incurred by them.

Vocational schools in Częstochowa in the years from 1939 to 1945

The disorganisation of Polish national life which was brought about by the outbreak of the World War II, commenced by the invasion of Poland by Hitler’s Germany, afflicted the spheres of education and science just as severely as all the others. The occupying forces set out to destroy all that bore the hallmarks of being Polish, evicting teaching staff and students from the school buildings, confiscating school equipment and subjecting teachers as well as students to forced labour, death, starvation, and torture in the name of achieving occupier’s political goals. However, the Polish school community did not remain indifferent to the actions of the enemy. Quite the opposite, in fact: it took up the fight by means of organizing clandestine tuition and also engaging in conspiratorial activities, which cost the lives of numerous teachers and students of the vocational schools of Częstochowa.

Migrations during the Roman conquest of Gaul in 58–51 BC: A historical and anthropological approach Caesar’s Commentarii de bello Gallico are a unique Roman source containing information on barbarian migrations in the 1st century BC. Despite numerous studies dedicated to Caesar’s narrative style, there still is a lack of reflection on the possible causes of migrations and the attitude of wan­dering barbarians to the Roman rule. Contemporary scholars have a tendency to see barbarians as Rome’s ‘eternal’ enemies, and often assume that they ‘must’ have manifested aggressive attitudes. By incorporating anthropological reflection and adopting the ‘other’s’ perspective, it is possible to better understand mechanisms prompting barbarians to look for a new homeland. No less of an important aspect is the reconstruction of Caesar’s way of presenting the phenomenon of migration, which allows us to explain why he treated it as hostile in every case.

Russian punctuation is one of the organizing means of artistic communication. In each individual work of art, one can speak of a system of punctuation marks (or their absence) that define its general idea. The dialogue of artistic discourse is created both by traditional and individually-authored division of the artistic space – this predetermines the invariance of meaning in the process of its actualization when generating and during speech subjects’ perception of statements in the process of communication.

The present work intends to analyze the application of Unmanned Aerial Vehicle (UAV) as a tool to aid in the management of physical flows in small construction sites. This perspective is mainly aimed at reducing transportation losses, as well as activities that do not aggregate value, both based on the principles of Lean Construction. The methodological aspects of this research are related based on the application of a case study. The study in question used as an experimental field a small work located in the municipality of Camaçari, state of Bahia, involving the following methodological steps: (i) data collection: by means of survey, photographic record, observation of movements and use of UAV to obtain aerial photographs, (ii) diagnosis: in order to understand the current situation  movements and disposal of materials) and (iii) proposal: which consists in the elaboration of a new site layout. The products prepared for the respective analyzes were thematic and georeferenced flow maps, whom, relate restrictively to the masonry execution service. The orthophotos obtained by the UAV were manipulated in Geographic Information System (GIS) software, allowing the identification of the distances walked by the workers in the execution of the analyzed service. The results indicated that the application of these tools can provide significant gains in reducing activities that do not aggregate value. In front of the proposed layout change, the construction site presented a reduction in transport losses of 41.8% in the ceramic block transport activity and 28.8% in the mortar transport activity, both related to the brick masonry service. The adopted method proved to be satisfactory for the understanding of the physical flow activities at the site in question, especially regarding the reduction of transport losses.

In the present research, the evolutionary method was applied to evaluate a residential building of four floors in the city of Toledo, Paraná. Thus, the purpose of the study was to verify and compare the difference in the final value of the property, through the use of different methodologies for budget realization. For this, three budget techniques were used: analytical budget, cost estimating using the CUB category PP – 4, corrected by the addition of existing and not considered costs in the standard project and, finally, estimation by the use of the CUB classification R8 - N, corrected by a coefficient according to the constructive typology. Finally, it was possible to perform comparative analysis of the data, verifying the percentages and the best budgeting alternative for the building under study evaluation. As a result, the average values of the property were obtained for the analytical budgets, CUB PP – 4 and CUB R 8 – N, respectively: R$ 2.089.512.59, R$ 2.214.370.01, R$ 2.29.,789, 62. Therefore, it was found that in both cases, the CUB overestimates the construction value.

Despite its relevance, the construction industry has been facing the same problems for decades. The lack of skilled labour, workers with few opportunities for professional growth, recurrent delays and high turnover rates are sector’s well known and hard to solve problems. Although important in the context of lean thinking, the concept of multi-skill faces resistance due to the learning effect and uncertanties about productivity. Considering the aforementioned situation, this review aims to compile the main results of studies carried out on the effects of multi-skill, when applied to the civil construction reality, as well as to analyse parameters related to the papers in question. A total of twenty-three publications were found in a systematic bibliometric review.  Results are partial and are part of a bigger research effort. It was observed that a multifunctional workforce benefits both employees and employers. A shortage of studies with real work environment results was discovered, with most of the papers focusing on computer models.

Published: October 2021

Minimizing construction waste is one of the major challenges of the sector in our country. Estimating the losses and waste generated in civil construction accurately is vital for minimizing them in the project stage. This vision allows engineers to visualize and explore possible corrective measures in order to increase construction efficiency. In addition, it can enable builders to identify critical processes in waste generation and plan control strategies. By integrating several projects into a single model, the process of modeling the construction information (BIM) can assist in the solution of this challenge. Through a questionnaire applied to engineers and architects, this work intends to explore the current reality and the potential of the application of BIM in the generation of construction waste.
Healthcare design assessment using semi-automated approaches for code checking

Published: October 2021

This paper reports initial research findings exploring the assessment of regulatory requirements in the healthcare design process, using different levels of automation – code checking. The methodological approach is Design Science Research, with an empirical study undertaken in close collaboration with an institution responsible for Primary Healthcare buildings in the UK. The main findings include understanding that the design of healthcare projects is intrinsically subjective, which is also reflected by the way regulations for healthcare buildings are developed. Thus, automated approaches for design assessment will only be suitable for the healthcare context if such approaches enable the consideration of requirements subjectivity. In fact, this consists of a change in the way subjectivity is considered in code checking research, which has traditionally been seen as problematic for the design assessment process, due to individual biases and potential misunderstandings. This research proposes that subjectivity in design assessment should be understood in terms of how its negative effects could be alleviated, but at the same time understanding it supports creativity and the uniqueness of human reasoning during the healthcare design process.

Published: October 2021

This study presents a comparison between a general programming routine and a reference routine from the literature. Both routines propose a cost estimate in the initial phases of the project using generative programming associated to BIM, which involves generating a model and extracting quantitative data through Dynamo, Revit and Excel software. The purpose of this study is to refine the reference routine to allow variations in the construction model by modifying only the data inputs, without having to change the programming structure for each new modeled solution. The research strategy adopted in this work is Design Science Research (DSR), which is oriented to the solution of relevant and pragmatic real-world problems. It has been divided into the stages of awareness, suggestion, development, evaluation and completion. In order to compare the results, the structural elements (beams, slabs and pillars) of a building were modeled through the general routine. The routine presented an error of 12% in relation to the budgeted cost and was considered a viable and fast solution for the creation of BIM models for preliminary cost estimates, in order to support decisions in the initial phases of the project.

Published: October 2021

As atividades da construção civil causam impactos ambientais desde a fase inicial da construção até a fase de conclusão da obra. Um dos principais impactos está relacionado à geração de partículas. Estudos sobre partículas sedimentadas (PS) provenientes da construção civil ainda são escassos, porém, constituem esforços necessários para subsidiar diretrizes e medidas de controle. O objetivo deste estudo foi medir os níveis do incômodo produzido por PS e a percepção deste incômodo pelos trabalhadores nas fases de produção do canteiro, Fase 1 de Terraplanagem e Fundações, Fase 2 de Estrutura, Vedações e Alvenarias e Fase 3 de Acabamentos. Este estudo foi realizado de janeiro a dezembro/2020 em sete canteiros de obras de um empreendimento residencial em construção localizado na Região Metropolitana de Salvador. Para a medição dos níveis de incômodo foram utilizados coletores sticky pads. A percepção dos trabalhadores foi coletada por meio de questionários. Os resultados indicaram altos níveis de incômodo, sendo a fase mais incômoda a de Estrutura, Vedações e Alvenarias. Ademais, 71% dos respondentes avaliaram a qualidade do ar de regular a ruim. Este trabalho permite o aprofundamento das investigações em canteiros de obras, subsidiando o entendimento do impacto das PS ao ser humano e ao ambiente.

Authors: Nunes Junior Francisco Sales , Andery Paulo Roberto Pereira
Published: October 2021

“Build to suit”, ou BTS, é um termo que identifica contratos de locação nos quais o imóvel é construído para atender os requisitos específicos do locatário já pré-determinado. Apesar da sua crescente aplicação no setor imobiliário, ainda são poucos os estudos apresentados na literatura brasileira acerca do tema. Este trabalho pretende contribuir com a gestão do processo de projeto em BTS, com foco na gestão de requisitos; o objetivo é caracterizar a definição de requisitos, desde a concepção do empreendimento, e propor diretrizes para definição de requisitos relacionados às necessidades do usuário e atributos de performance da edificação. O estudo de casos conduzido incluiu a revisão do referencial teórico, entrevistas e avaliação de documentação de empresas inseridas em empreendimentos BTS implementados em Belo Horizonte (MG) e em São Paulo (SP). Os resultados da pesquisa apontaram para a adequada definição de requisitos pelo locatário (cliente final / usuário), porém, limitados a aspectos construtivos da edificação, cumprimento de normas e legislação, abordagem essa tradicional da construção. Observou-se, portanto, significativa oportunidade para a proposição de diretrizes para melhoria da gestão de requisitos associados à performance do edifício em uso, objeto da abordagem “performance based design” (PBD), o que se apresenta neste trabalho.

Published: October 2021

Empreendimentos da construção civil são produtos diretamente avaliados pela relação qualidade-custo. Em ambientes de limitações orçamentárias, como característico de economias de países em desenvolvimento, o conhecimento da influência das múltiplas variáveis relacionadas ao custo final do empreendimento é fundamental para sua viabilidade como produto. Esta pesquisa tem como objetivo compreender como as decisões arquitetônicas e a geometria das edificações podem interferir no custo final das edificações. A unidade de análise constitui-se em seis empreendimentos residenciais de múltiplos pavimentos de construtoras do município de Maceió, Alagoas. Os indicadores considerados na análise dos projetos arquitetônicos foram: índice de compacidade (IC), densidade de paredes (DP) e porcentagem da área do pavimento tipo ocupada pela área de circulação (IA). Para cada indicador foi atribuída uma classe “ruim”, “bom” ou “ótimo”, em conformidade com o referencial teórico utilizado. O valor médio (VM) do IC foi de 53,68%, portanto, de classificação “ruim”. Para a DP, os resultados foram satisfatórios (“ótimo”) para todos os seis projetos analisados, com VM de 0,1188. O indicador IA apresentou VM de 11,07%, classificado como “bom”. A análise e comparação de projetos de arquitetura a partir de indicadores auxiliam no processo de tomada de decisão de projetistas na busca pela melhor relação qualidade-custo dos empreendimentos de edificações multifamiliares da construção civil.

O objetivo foi realizar uma comparação entre as periodicidades de manutenção propostas pelo Guia da CBIC e as normas e documentos técnicos disponíveis no âmbito nacional. Os dados para comparação foram extraídos de normas técnicas e fabricantes de forma online, foram analisadas as normas pertinentes para os sistemas, manuais de instalação, manuais técnicos, manuais de uso, informações técnicas e o certificado dos produtos, buscando localizar informações a respeito da periodicidade da manutenção predial para o sistema hidrossanitário e elétrico. Posteriormente foi realizado um comparativo entre os dados obtidos e o guia nacional para elaboração do manual de uso realizado pela Câmara Brasileira da Indústria da Construção - CBIC. A revisão documental resultou em 23 normas do sistema hidrossanitário e 22 do elétrico analisadas, entre elas apenas a NBR 5674 possui informações a respeito da periodicidade da manutenção. Para os fabricantes foram analisadas 87 empresas e não foram encontradas informações sobre o assunto que pudessem contribuir para o comparativo. A análise comparativa entre os dados demonstrou que as atividades e periodicidades propostas não são similares às informações técnicas coletadas. Conclui-se que as informações que constam no guia da CBIC não estão disponíveis em normas técnicas nacionais e nem pelos fabricantes.

Published: October 2021

A geração de resíduos da construção civil (RCC) atrelada à ausência ou ineficiência do planejamento da gestão de RCC em canteiro de obras pode acarretar em problemas de organização e segurança do trabalho. Nesse contexto, o objetivo principal deste trabalho foi apresentar procedimentos para dimensionamento de recipientes e equipamentos voltados ao armazenamento e transporte de RCC em canteiros de obras. Para isso, foram propostas soluções de manejo desses resíduos em um estudo de caso de edificação residencial de múltiplos pavimentos por meio dos cálculos de número de recipientes necessários e suas frequências de esvaziamento, além da realização de estimativa de custos do uso de recipientes de armazenamento. Resultados apontaram a necessidade por pavimento de 2 bags, 3 bombonas e 1 tambor para a macroetapa de estrutura e vedação, e 2 bags, 1 bombona e 1 tambor para a macroetapa de acabamento. O custo total estimado desses dispositivos para todos os pavimentos representou 0,07% do custo total do empreendimento. Conclui-se que as construtoras devem utilizar indicadores de geração por macroetapa de obra associados ao conhecimento das opções de dispositivos de acondicionamento e transporte, a fim de otimizar por meio de dimensionamento as quantidades, capacidades e frequências de coleta dos recipientes coletores.

Authors: Mahmutović Arzija
Published: October 2021

Integrated teaching activities enable the connection of the contents of different subjects. This approach is characterized by the examination of every problem, subject or research topic from a multitude of perspectives, thus gathering a number of information from different disciplines. It is in line with real life situations in which a problem is seen as a biological and historical cir- cumstance that is made of mathematical and at the same time artistic, linguistic and other characteristics. Ultimately, the assessment is carried out by the ending result, essay or a problem solution and application of knowledge, thus changing the teacher student relationship by giving the student more time for interconnec- tion and comprehension of terms and phenomena that describe our reality. This paper contains results of an experimental study that was carried out on a sample of hundred students. The resulting data point to a conclusion that the application of integrated teaching activities gives better results with respect to the traditional model when it comes to the formation of mathematical terms. Moreover, it must be noted that a greater expression of psychological functions was achieved by the application of different didactical and methodological meth- ods and forms.
VIETNAMESE ENGLISH-MAJORED STUDENTS’ USE OF LISTENING STRATEGIES
Authors: Duy Vo Hoang , Quan Nguyen Hai
Published: October 2021

The crucial role of listening skill in language learning has been well acknowledged, yet attention to this skill remains modest. Numerous studies investigating learners’ listening performance have identified listening strategies as a key factor contributing to the success of effective listeners. This study, using a Likert-scale questionnaire, examined the listening strategies employed by 81 Vietnamese English-majored students, who were divided into two groups - effective and less effective listeners based on an IELTS proficiency test. Findings showed that listening strategies were used at a relatively high level with the metacognitive group employed most frequently compared to cognitive and socio-affective strategies. Lowering anxiety, predicting and planning, resourcing, repetition, and cooperation were found most commonly employed individual strategies. Although no significant differences were found between the groups’ use of the three overarching strategy categories, several discrepancies were identified concerning their use of individual strategies, which provides important implications for listening pedagogical adjustments in this particular context.

E - Belediye Uygulamasını Kullanan Kent Yerleşiklerinin Görüşlerinin Değerlendirilmesi: Buca Belediyesi Örneği
Authors: DEMİRCİ Kıvanç
Published: October 2021

Çalışma, e-belediye hizmetini kullanan bireylerin görüşlerinin değerlendirilmesi ve yaşanılan sorunların tespit edilip bu sorunlara yönelik çözüm önerileri getirilmesi amacını taşımaktadır. Bu amaç doğrultusunda uluslararası ve ulusal e-belediye terminolojisi açıklandıktan sonra İzmir ilinin Buca ilçesinde yaşayan bireylerin e-belediye konusundaki görüşleri ve yaşanılan sorunlara vurgu yapılmıştır. Çalışma nicel bir araştırma yöntemi olan anket araştırması metoduna dayandırılmıştır. Bu bağlamda çalışmanın sonuç bölümünde İzmir ilinin Buca ilçesinde yaşayan ve e-belediye uygulamasını kullanan bireylerle yapılan anket görüşmesinin çıktılarına yer verilmiştir.

Araştırma sonucunda düşük eğitim seviyesinde olan, orta yaş ve üzeri bireylerin, e-belediye uygulamalarına karşı gizlilik, güvenlik endişeleri nedenleriyle kuşkulu yaklaştıkları, bilgisayar, cep telefonu gibi elektronik aygıtlarla daha fazla zaman geçiren, sosyal medya uygulamalarına üyelikleri olan bireylerin ise e-belediye uygulamalarına daha olumlu ve bilinçli yaklaştıkları görülmektedir. Ayrıca kamu hizmetlerinin alımını zaman ve maliyet açısından kolaylaştıran e-belediye hizmetlerine engelli ve her kesimden bireyin erişmesinin kolay olmadığı anlaşılmıştır. Bu sebeple, 2000 yılı sonrası kamu yönetiminde dijital dönüşümün önemli çıktıları arasında olan e-uygulamaların kazanımları korumakla birlikte bu uygulamaları engelli, yaşlı ve eğitim düzeyi düşük bireylerin de rahatça yararlanabileceği şekilde geliştirilmesi gerekmektedir.

Osmanlı Devleti için bu madenler içerisinde kömür madenlerinin sanayi devrimi ile birlikte önemi ve değeri daha da artmıştır. Nitekim kömür madenleri buharlı gemiler, trenler gibi devrin en önemli icatlarına yakıt olarak kullanılmıştır. Ancak kömür madenlerinin işletilebilmesi emek ve sermaye gücüne bağlıdır. Bu bakımdan Osmanlı Devleti madenlerin daha aktif bir şekilde işletilebilmesi amacıyla bazen maden çevresindeki yerleri madenin çıkarıldığı bölgeye mali birimler oluşturacak şekilde bağlamış bazen de madenin bulunduğu bölgeyi idari olarak müstakil bir birime dönüştürmüştür. Bu sayede hem emek gücü halledilmeye hem de maden çıkarımında bürokratik kolaylıklar sağlanmaya çalışılmıştır. Bu çalışmada Ereğli Kömür Madeni’nin gerek devlete sağladığı gelir gerekse sanayi vesair kollara yaptığı katkılar dolayısıyla Ereğli kazasının neden kaymakamlığa dönüştürüldüğü özellikle arşiv kaynakları çerçevesinde ele alınacaktır. Böylece Osmanlı mülki yapısının belirlenmesinde mali birimlerin de önemli bir yerinin olduğu ortaya konulmuş olacaktır.
A predictive viscosity model for aqueous electrolytes and mixed organic-inorganic aerosol phases
Authors: Lilek Joseph , Zuend Andreas
Published: October 2021

Abstract. Aerosol viscosity is determined by mixture composition and temperature, with a key influence from relative humidity (RH) in modulating aerosol water content. Aerosol particles frequently contain mixtures of water, organic compounds and inorganic ions, so we have extended the thermodynamics-based group-contribution model AIOMFAC-VISC to predict viscosity for aqueous electrolyte solutions and aqueous organic-inorganic mixtures. For aqueous electrolyte solutions, our new, semi-empirical approach uses a physical expression based on Eyring's absolute rate theory, and we define activation energy for viscous flow as a function of temperature, ion activities, and ionic strength. The AIOMFAC-VISC electrolyte model's ion-specific expressions were simultaneously fitted, which arguably makes this approach more predictive than that of other models. This also enables viscosity calculations for aqueous solutions containing an arbitrary number of cation and anion species, including mixtures that have never been studied experimentally. These predictions achieve an excellent level of accuracy while also providing physically meaningful extrapolations to extremely high electrolyte concentrations, which is essential in the context of microscopic aqueous atmospheric aerosols. For organic-inorganic mixtures, multiple mixing approaches were tested to couple the AIOMFAC-VISC electrolyte model with its existing aqueous organic model. We discuss the best performing mixing models implemented in AIOMFAC-VISC for reproducing viscosity measurements of aerosol surrogate systems. We present advantages and drawbacks of different model design choices and associated computational costs of these methods, of importance for use of AIOMFAC-VISC in dynamic simulations. Finally, we demonstrate the capabilities of AIOMFAC-VISC predictions for phase-separated organic-inorganic particles equilibrated to observed temperature and relative humidity conditions from atmospheric balloon soundings. The predictions for the studied cases suggest liquid-like viscosities for an aqueous electrolyte-rich particle phase throughout the troposphere, yet a highly viscous or glassy organic-rich phase in the middle and upper troposphere.

Abstract. Residential wood combustion is a widespread practice in Europe with a serious impact on air quality, especially in mountainous areas. While there is a significant number of studies conducted in deep urbanized valleys and basins, little is known about the air pollution processes in rural shallow hollows where around 30 % of the people in mountainous areas across Europe live. We aim to determine the influence of ground temperature inversions on wood combustion aerosol pollution in hilly, rural areas. The study uses Retje karst hollow (Loški Potok, Slovenia) as representative site for mountainous and hilly rural areas in central and southeastern Europe with residential wood combustion. Sampling with a mobile monitoring platform along the hollow was performed in December 2017 and January 2018. The backpack mobile monitoring platform was used for the determination of equivalent black carbon (eBC) and particulate matter (PM) mass concentrations along the hollow. To assure high quality of mobile measurement data, intercomparisons of mobile instruments with reference instruments were performed at two air quality stations during every run. Our study showed that aerosol pollution events in the relief depression were associated with high local emission intensities originating almost entirely from residential wood burning and shallow temperature inversions (58 m on average). The eBC and PM mass concentrations showed stronger associations with the potential temperature gradient (R2 = 0.8) than with any other meteorological parameters taken into account (ambient temperature, relative humidity, wind speed, wind direction and precipitation). The strong association between the potential temperature gradient and pollutant concentrations suggests that even a small number of emission sources (total 243 households in the studied hollow) in similar hilly and mountainous rural areas with frequent temperature inversions can significantly increase the levels of eBC and PM, and deteriorate local air quality. During temperature inversions the measured mean eBC and PM2.5 mass concentrations in the whole hollow were as high as 4.5 ± 2.6 µg m–3 and 48.0 ± 27.7 µg m–3, respectively, which is comparable to larger European urban centres.
Short communication: Modelling competing effects of cooling rate, grain size and radiation damage in low temperature thermochronometers

Abstract. Low temperature multi-thermochronometry, in which the (U-Th)/He and fission track methods are applied to minerals such as zircon and apatite, is a valuable approach for documenting rock cooling histories and relating them to geological processes. Here we explore the behaviours of two of the most commonly applied low temperature thermochronometers, (U-Th)/He in zircon (ZHe) and apatite (AHe), and directly compare against the apatite fission track (AFT) thermochronometer for different forward-modelled cooling scenarios. We consider the impacts that common variations in effective spherical radius (ESR) and effective Uranium concentration (eU) may have on cooling ages and closure temperatures under a range of different cooling rates. This exercise highlights different scenarios under which typical age relationships between these thermochronometers (ZHe > AFT > AHe) are expected to collapse, or partially to fully invert. We anticipate that these predictions and the associated software we provide will be a useful tool for teaching, planning low temperature multi-thermochronometry studies, and for continued exploration of the relative behaviours of these thermochronometers in the temperature-time space through forward models.

Abstract. Ingesting near-real-time observation data is a critical component of many operational hydrological forecasting systems. In this paper we compare two strategies for ingesting near-real-time streamflow observations into Long Short-Term Memory (LSTM) rainfall-runoff models: autoregression (a forward method) and variational data assimilation. Autoregression is both more accurate and more computationally efficient than data assimilation. Autoregression is sensitive to missing data, however an appropriate (and simple) training strategy mitigates this problem.

Translating the Jump of a Horse – two translations of Federico García Lorca’s Poeta en Nueva York
Authors: Holm Nanna
Published: October 2021

This article deals with metaphor translation emphasising the common ground between translation theory and Cognitive Linguistics (CL). Within the framework of CL, a comparative study of two Danish translations of Spanish poet Federico García Lorca ’s ‘Poeta en Nueva York’ is presented, focusing on a selection of metaphors that form networks throughout the work in question. It is then analysed if and how these metaphoric networks have been successfully transferred into the target language (TL). In conclusion, some remarks are made on the contribution of CL to the overall discussion of the translatability of metaphors.
