La evolución reciente de las exportaciones españolas de servicios no turísticos
Authors: Martín Machuca César , García Coral 
Published: July 2023

Motivación
El elevado dinamismo de las exportaciones de servicios no turísticos tras la pandemia ha contribuido significativamente a la recuperación de la economía española, por lo que resulta de interés analizar su evolución reciente.
Ideas principales
•El crecimiento acumulado por las exportaciones reales de servicios no turísticos entre 2020 y 2022 ascendió prácticamente al 50 %, de manera que, en 2022, estas se situaron cerca de un 20 % por encima del nivel de 2019, brecha sensiblemente superior a la de otros componentes de la demanda final.
•La recuperación de las exportaciones de servicios no turísticos tras la pandemia ha intensificado el crecimiento sostenido de esta partida observado en las últimas décadas y se ha apoyado, principalmente, en los servicios empresariales, de transporte y tecnológicos, dirigidos, sobre todo, al área del euro y a América del Norte.
•La capacidad competitiva de las grandes empresas exportadoras en España, que suelen pertenecer a grupos empresariales, podría explicar, al menos en parte, el elevado dinamismo de las exportaciones de servicios no turísticos tras la pandemia.
Recent Work on Skepticism in Epistemology
Authors: Ranalli Chris 
Published: July 2023

Abstract
This paper critically surveys 20 years of recent work on radical skepticism. It focuses on three key issues. First, it starts by exploring how philosophers have recently challenged our understanding of radical skeptical arguments. It then unpacks and critically evaluates some influential reactions to radical skepticism: structuralism, knowledge-first epistemology, epistemological disjunctivism, and hinge epistemology. Third, it explores some novel developments of pragmatism, like pragmatic skepticism, gauges its anti-skeptical import, and reflects on the ways in which radical skeptical epistemology and ethics might meet.

Published: July 2023

Современные технологии внедряются повсеместно, не является исключением и сфера транспорта. Одной из наиболее популярных и обсуждаемых представляется технология искусственного интеллекта, способная упростить и решить ряд задач, с которыми общество сталкивается ежедневно. Несмотря на привлекательность использования таких систем, ряд проблем видится неизбежным, к числу которых относится высвобождение трудовых ресурсов, столкновение с ситуацией, при которой нужно осуществлять выбор искусственному интеллекту и многие другие. В настоящей статье автором предпринята попытка сформулировать предложения по развитию законодательства в части применения искусственного интеллекта в сфере транспорта в целях избежания обозначенных проблем.
Modern technologies are being introduced everywhere, and the transport sector is no exception. One of the most popular and discussed is artificial intelligence technology, which is able to simplify and solve a number of tasks that society faces on a daily basis. Despite the attractiveness of using such systems, a number of problems seem inevitable, including the release of labor resources, a collision with a situation in which artificial intelligence needs to make a choice. In this article, the author attempts to formulate proposals for the development of legislation regarding the use of artificial intelligence in the field of transport in order to avoid the identified problems.
Biomarcadors paleoclimàtics a la conca de la Guaiana (Atlàntic tropical occidental)
Authors:   , Rama-Corredor Óscar 
Published: July 2023

The main objective of this thesis is the study of a marine sediment core located in front of French Guiana (7°48’75’’N i 53°0’80’’W -1233m bsl and 39m length), in northern South America. The last 415,000 years were studied at high resolution by identification and quantification of organic fossil compounds.
Two types of biomarkers were used: continental (n-alkanes and n-alcohols) which are synthesized by higher plants and marine (C37 alkenones) which are synthesized by phytoplankton (some species of Hapthophyceae). The former provide information on precipitation and vegetation changes in the Amazon basin and the later show the sea surface temperatures variations in the studied area.
Despite being closer to equator, the Guiana region records perfectly the glacial/interglacial variations (last 4 cycles) and the submillennial variability, including the D-O and HE that are characteristic of the last glacial period.
En aquesta tesi doctoral s'estudia un testimoni marí recollit davant de les costes de la Guaiana francesa (7°48'75''N i 53°0'80''O, -1233m i 39m de llargada), a la regió tropical de Sud-Amèrica, àrea fins ara no considerada des de la perspectiva paleoclimàtica. L'estudi de compostos orgànics fòssils ha permès reconstruir el clima esdevingut durant els últims 415.000 anys. S'han fet servir dos tipus de biomarcadors: continentals (n-alcans i n-alcohols de cadena lineal) provinents de plantes superiors i marins (C37 alquenones) que sintetitzen algues (algunes espècies d'haptofícies). Els continentals donen informació sobre els canvis de precipitació i vegetació que hi ha hagut a la regió amazònica. Els marins donen informació sobre les variacions de temperatura superficial a l'oceà en l'àrea d'estudi. La regió de la Guaiana, tot i la proximitat a l'equador, registra perfectament els canvis glacials/interglacials al llarg dels últims 4 cicles climàtics. També permet observar els esdeveniments produïts a escala submil·lenària, inclosos els D-O i HE característics de l'últim període glacial.
Discrete volume method : a variational approach for brittle fracture
Authors:   , Cardoso Nungaray Víctor Eduardo 
Published: July 2023

This thesis presents a proposal to simulate mechanics and dynamics of brittle fracture. A variational formulation is used to describe Lagrangian mechanics, by minimizing the difference between potential and kinetic energy of the system, obtaining a pair of partial differential equations; the solution of these equations corresponds to the displacement field and damage phase-field respectively. Such an equations are coupled in the sense that the damage field is used in the first equation and the displacement field is used in the second one.

In this work we propose a numerical method based on control volumes to solve the differential equations, extending the formulation to support the separation of control volumes, processing these volumes as discrete entities. This treatment results in accurate calculations of stress field and the nucleation of new internal fractures that can be propagated through domain creating multiple bifurcations.

To integrate equations inside control volumes we introduce a family of polynomial splines that we refer as homeostatic splines, since its derivatives are null at vertices with a smooth function variation between adjacent volumes. Furthermore, we propose a shape function with trigonometric components for dynamic analysis, allowing bigger time steps that with traditional approaches.

Finally, we perform ten numerical experiments to show the effectiveness of the method and to compare our results with those published by other authors.
La tesis presenta una propuesta para simular la mecánica y dinámica del fenómeno de fractura frágil. Se plantea una formulación variacional que consiste en minimizar la diferencia entre la energía potencial y la energía cinética del sistema, obteniendo así un par de ecuaciones diferenciales parciales, cuya solución corresponden al campo de desplazamientos y al campo de daño respectivamente. Estas ecuaciones están acopladas en el sentido de que el campo de daño se usa en la primera ecuación y el de desplazamientos en la segunda. En este trabajo se propone un método numérico basado en volúmenes de control para resolver las ecuaciones diferenciales, además el modelo se extiende para soportar la separación de los volúmenes de control, tratándolos posteriormente como entidades discretas, esto permite calcular con precisión el campo de esfuerzos y la aparición de fracturas internas que pueden propagarse a través del dominio y crear múltiples bifurcaciones. Para integrar las ecuaciones dentro de los volúmenes de control se introducen una familia de splines polinomiales, que se les refiere como splines homeostáticos, ya que sus derivadas son nulas en los vértices y el cambio de la función entre dos volúmenes contiguos es suave. Además, se propone una función de forma con componentes trigonométricas para el análisis dinámico, permitiendo pasos de tiempo más grandes que con enfoques tradicionales. Finalmente se realizan diez experimentos numéricos para mostrar la eficacia del método y contrastar los resultados con aquéllos publicados por otros autores.

PREVENTION OF INFECTIOUS COMPLICATIONS OF TRACHEOSTOMY IN PATIENTS WITH HEAD AND NECK CANCER PATHOLOGY
Authors: Burjan O. V. , Yurevich N. O. , Kuchmiy Yu. Yu. , Zmeyev V. O. 
Published: July 2023

Summary. Introduction. A tracheostomy is still widely used in the head and neck oncology practice, but the rate of infectious complications remains high.
Goal. Optimization of the prevention and treatment of the tracheostomy complications in patients with oncological pathology of the head and neck based on taking into account the flora that is seeded from the tracheostomy.
Materials and methods. The 1st stage of the study consisted in examining of the 100 patients after tracheostomies performed in the period 2018-2022 (planned — 76, emergency — 24). The age of the patients ranged from 40 to 70 years old. The indication for the tracheostomy was obstruction of the respiratory tract by a tumor process of the larynx and the laryngopharynx. All surgery operations were performed under the local infiltration anesthesia, according to the standard technique for the permanent tracheostomy. At the 2nd stage, the proposed methods of the postoperative management of the patients to prevent the infectious complications were evaluated: processing of the cannula with a combination of 0.01 % solution of the miramistin with 10 mg of the chymotrypsin or a combination of 0.5 % solution of the dioxidin and 10 mg of the chymotrypsin.
Results and their discussion. At the 1st stage of the study, various complications were detected, but in all cases there were infectious complications. Most often, after 7 days, Pseudomonas aeruginosa was cultured from the trachea, followed by Acinetobacter baumannii in 2nd place. The use of 0.02 % chlorhexidine solution to process the cannula was not effective. The flora that is cultured determines the antiseptic agent that should be used to process the cannula.
Conclusions. 1. Infectious complications after the tracheostomy are inevitable due to disruption of the natural path of air movement. 2. The flora sown from the tracheostomy cannula within 14 days after the tracheostomy is diverse. 3. It is advisable to use double-lumen tracheostomy cannulas, the inner part of which should be processing with the antiseptics depending on the flora found in the tracheal contents. 4. The combination of the 0.01 % miramistin solution with 10 mg chymotrypsin for the cannula processing is effective against P. aeruginosa. A combination of 0.5 % dioxidin solution and 10 mg chymotrypsin is effective against S. aureus, A. baumanii and K. pneumoniae.

The study examined knowledge, attitude and practice towards nosocomial infection prevention among Primary Healthcare workers in Rivers-West Senatorial Zone. The study was guided by three research questions, adopted the cross-sectional descriptive survey design and was conducted in Rivers-West senatorial district in Rivers State. The population of the comprised about 781 Health Care workers (HCWs) working in all the primary healthcare facilities in Rivers West Senatorial district. The multi stage sampling procedure was used to select 475 healthcare workers from the facilities in Rivers West Senatorial Zone. The instrument for data collection was a set of structured questionnaire titled “Knowledge, Attitude and Practice towards Nosocomial Infection Prevention Questionnaire (KAPNIPQ). Data derived from the field were analyzed using the statistical tools such as frequency and percentage, mean and standard deviation to answer the research questions. The result showed that the respondents have good knowledge of nosocomial infection prevention as majority had knowledge score between 70-100%; also, Primary Health care workers were found to have positive attitude towards nosocomial infection prevention as the mean scores obtained for all the items were above the criterion mean of 2.50, it is also worthy of note that Primary Healthcare workers had positive practice in relation to nosocomial infection prevention in Rivers West Senatorial Zone. Based on the findings, it was concluded that the primary health care workers had good knowledge, positive attitude and positive practice towards nosocomial infection prevention. It was therefore recommended that there should be regular supportive supervision of healthcare workers to ensure positive practice towards nosocomial infections prevention.

O fígado desempenha um papel essencial na adaptação metabólica materna durante a gravidez. A plasticidade metabólica está bem descrita na literatura, mas alterações da morfologia hepática na gravidez permanecem obscuras. Nosso objetivo foi investigar o efeito da restrição calórica (RC) na organização estrutural e no metabolismo do fígado de ratas prenhes no 21o dia gestacional (21o dG). Ratas Wistar prenhes foram divididas em Grupo Controle (C, n = 6, dieta basal) e Grupo Restrito (R, n = 6). Este foi alimentado com 50% da dieta consumida por C. No 21o dG, após anestesia e coleta de sangue por punção cardíaca para análise bioquímica, os fígados foram coletados, pesados e fragmentados para histologia (hematoxilina-eosina) ou congelados em biofreezer. As ratas R apresentaram menor massa de fígado em relação ao peso corporal, assim como uma diminuição significativa no glicogênio hepático, na glicose, no colesterol e no triacilglicerol séricos quando comparadas às C. A análise morfológica não mostrou diferença significativa entre os grupos quanto à estrutura ou à organização de hepatócitos. Os lóbulos hepáticos não apresentaram sinais de inflamação, esteatose ou fibrose em nenhum dos grupos. A estrutura e a distribuição de vasos sinusóides também foram semelhantes. Os dados demonstram que a RC gestacional alterou o tamanho do fígado, causando diminuição de massa e de reserva energética; porém, a organização estrutural hepática foi preservada.
Virtuous circles: Transformative impact and challenges of the social and solidarity circular economy
Authors: Monciardini David , Rocca Laura , Veneziani Monica 
Published: July 2023

AbstractThe conventional view tends to consider the social dimension of the circular economy as conspicuous by its absence. This paper draws attention to business strategies and organisational practices that bring together the valorisation of wasted material resources and marginalised people. Theoretically, we build on the literature on hybrid forms of organisation and management typical of the social and solidarity economy (SSE)—for example, social cooperatives—to introduce a more realistic and dynamic model of social and solidarity circular economy (SSCE). Offering a definition of SSCE based on existing hybrid organisational practices rather than abstract ideals, we juxtapose the SSCE and the current corporate‐led CE approach across three key dimensions: strategic aims; organisational boundaries and governance mechanisms. To illustrate how this SSCE works, we focus on the case of CAUTO, an Italian network of circular social cooperatives based in Northern Italy. We identify three intertwined steps through which CAUTO developed an effective SSCE strategy: social circular innovation, networked actions and participatory scaling up. Taken together, our findings suggest a realistic pathway to business circularity that is inclusive, pragmatic and embedded in social practices.
Cytomorphologic, immunophenotypical and molecular features of pancreatic acinar cell carcinoma

Published: July 2023

AbstractObjectivesAs a rare tumor in pancreas, pancreatic acinar cell carcinoma (PACC) possesses a distinct molecular feature from pancreatic ductal carcinoma (PDAC). Though the diagnosis of PACC is often established based on cytology specimens, its cytologic diagnosis can be challenging. Furthermore, the correlation between PACC cytomorphology and its unique different molecular alterations have not been fully explored.MethodsCytology features were analyzed in 8 histologically proven PACC and cytohistological correlation was performed. Immunocytochemistry for trypsin, chymotrypsin, BCL10, synaptophysin, chromogranin A, INSM1, β‐catenin, and Ki‐67 was assessed. Comprehensive molecular profiling and additional targetable treatment biomarker assessment were also performed.ResultsThe cohort included 4 mixed acinar‐neuroendocrine carcinomas, 3 pure PACCs, and 1 mixed acinar‐ductal carcinoma. Immunophenotypical features are consistent with diagnoses of PACC or PACC with neuroendocrine features. Identified genetic alterations included somatic mutations of CTNNB1, TP53, MAP2K1, PTEN, RAC1, germline mutations of NBN and BRAC2, and gene fusion of CCDC6‐RET.ConclusionsThe current study is the first attempt to explore the correlation between the cytomorphology characteristics and molecular features of PACC and a few intriguing findings were observed. Further validation in larger cohorts is warranted.
