Primeras observaciones y críticas al Proyecto de “Ley que establece la Ley Integral de Salud Mental” (2024)
Authors: Carrasco-Jiménez Edison 
Published: September 2024

El presente artículo tiene por objetivo el análisis dogmático del Proyecto de “Ley que establece la Ley Integral de Salud Mental” (2024), enviado por el Ejecutivo al Congreso. Se detectaron tres errores de forma, en tanto errores de redacción, y, además, y desde la crítica del derecho, cinco problemas de contenido. Se concluye que, los problemas de contenido no son baladíes, ya que, la concepción de las personas con padecimiento en el ámbito de la salud mental, según este Proyecto: a) está mirado desde un “paradigma de la patología”, y no un “paradigma de la diversidad”; b) un equivocado o incompleto entendimiento de la ecología, respecto de este tipo de personas y en relación al medio ambiente; c) que algunas disposiciones se encuentran en oposición a la libertades civiles y a los derechos humanos, contribuyendo a la construcción de un Estado totalitario y, por ende, policía, y; d) una programación de ausencia de sometimiento al derecho de una parte del aparato estatal. Por lo mismo, se recomienda la necesaria modificación de los aspectos analizados, si se va a discutir en el Congreso, este proyecto.
Transformative education for medical postgraduates: centring planetary health
Authors: Floss Mayara , Mauad Thais , Khoo Su-Ming , Saldiva Nascimento Paulo Hilário 
Published: September 2024

The purpose of this article is to report, reflect upon and learn from a postgraduate course in Planetary Health. The 195 hours postgraduate course occurred in 2022 and involved 44 students at the Department of Pathology at University of São Paulo in Brazil. The course activities for students were carried out remotely and included self-reflexive, dialogical and creative learning methods. The evaluation was composed of four aspects: participation; poetic memory of encounters; 'plant' or planning a planetary health action; and 'penning'. This study used a qualitative method of thematic analysis to verify three main learning activities: poetic memories, “‘Plant’ a planetary health action” and ‘Penning’. From the 44 students enrolled, 26 fulfilled the optional formulary given consent to participate in this study. ‘Planting’ a planetary action was organized in different levels: community, work and research, interpersonal, personal. In the ‘penning’ analysis, students repeatedly referred to art and future as core to learn about planetary health. This could be induced by the way that the course was structured, but rises to a point of the arts’ potential to create awareness and a transformative topic for medical education touching other dimensions of learning like emotions and hope.
Racism, Segregation, Acceptance: American Economics and Black Labor Studies, 1885-1965
Authors: Rutherford Malcolm Henderson 
Published: September 2024

This paper investigates the failure of American economists to engage positively with Black issues and Black students until recent times. The paper traces this history, beginning with the early American Economic Association and the overt racism to be found in the AEA Publications series and other major economics journals up to about 1910. It is noteworthy that during this time W. E. B. Du Bois attempted to gain acceptance within the AEA, but his efforts ultimately failed. Following this, there was a long period of some 30 years during which economic issues relating to the Black population were rarely considered at all by White economists. This despite major events such as Great Migration of Black people to Northern cities. Issues having anything to do with race relations, including discrimination in labor markets, became seen as outside of the proper domain of economics. These issues were, however, dealt with by Black scholars working within Black organizations and Black colleges, mostly in sociology or history departments rather than in economics. They created what became known as Black labour studies, but the work they produced was largely ignored by the established economics profession. Other disciplines such as sociology developed different trajectories. It was only in the 1940s that a few works dealing with Black labor issues found acceptance in leading economics journals, and it was not until in the mid 1960s, that a more substantial literature developed.

The article considers the problem of reducing the oxygen content in oxidation gases during the oxidation process in petroleum bitumen production. The increased oxygen content in the exhaust gases is a consequence of deficiencies in the oxidation apparatus. In bitumen production processes, a hollow oxidation column is used, its main disadvantage is the incomplete use of atmospheric oxygen during the oxidation process due to the small specific surface area of the phase contact. This factor, in turn, causes the possibility of coking of oxidation column walls, metal corrosion and explosion in the gas phase. The need to reduce the oxygen content in oxidation gases is determined by environmental standards, technological regulations and safety precautions of oil refineries. To ensure safety and prevent fires in the column during the oxidation process, it is necessary to control the oxygen content in the oxidation gases. This parameter is limited by technological regulations to 7–8 % vol.The study of the existence of a relationship between the parameters of the process and the construction of a mathematical model of the process is based on data from operator’s logs of a bitumen production plant, which, in turn, allows us to build the most accurate mathematical model for a specific refinery.Analysis of operator’s logs using statistical methods of data processing made it possible to bring existing data into the required system, to identify patterns and dependences of the oxygen content in oxidation gases on process parameters. During the study, both descriptive statistics and data analysis were carried out based on correlation and regression analysis. During the analysis, significant excesses of the oxygen content in the oxidation gases from the established safety standards were revealed.Based on the research and literature data on the process of petroleum bitumen production using correlation and regression analysis, a mathematical model describing the dependence of the oxygen content in oxidation gases on the process parameters has been developed. This model makes it possible to most accurately select the parameters of the oxidation process to maintain the oxygen content in the oxidation gases within acceptable limits.

The Fischer – Tropsch synthesis makes it possible to obtain various types of products depending on the catalyst used (linear long-chain alkanes, components of motor fuels, gases, heavy products). The article provides an analysis of the development of industrial Fischer – Tropsch synthesis technologies. The authors investigated the Fischer – Tropsch process on a model mixture consisting of carbon monoxide and hydrogen on a bifunctional zeolite-free catalyst consisting of a carrier – montmorillonite treated with sulfuric acid, intercalated with a polyvalent zirconium cation, promoted with a solution of cobalt nitrate and organometallosiloxane (ruthenium carbonophenylsiloxane), which allows to obtain components of motor fuels in one stage. The studies were conducted at temperature 210 °C (previously conducted experiments indicate that at this temperature the maximum yield of iso-paraffins is achieved) and pressures 4, 6, 8 MPa. It has been found that the highest yield of iso-paraffins is achieved at pressure 6 MPa. The analysis of the obtained gasoline fraction for compliance with State Standard 32513-2013 for motor gasoline has been carried out. It has been established that the product complies with environmental class K5 and can be used as a component of commercial motor fuel.

Research on the separation of emulsions based on «I20-A» grade industrial oil and oil from the Tumutuk field using polysulfonamide (PSA) membranes has been carried out. In order to intensify the process and increase resistance to oiling, polymer filters were treated with corona discharge plasma. It was found that as a result of the modification, the separation efficiency increased to ≈ 90 %, and productivity increased up to 10 times. The results of the study allow us to recommend the use of a proven membrane ultrafiltration method for treating wastewater from emulsified oils, for example, in the composition of used cutting fluids or cleaning solutions. Corona plasma treatment improves the efficiency and productivity of water-oil emulsion separation. It was revealed that when separating an oil-water emulsion, productivity as a result of membrane modification in most cases, contrary to what was expected, decreases. This circumstance is explained by the more complex qualitative and, accordingly, dispersion composition of oil, which contributes to clogging of filter pores. Thus, to purify water from emulsified oil with polymer membranes, it is necessary to provide an additional technological solution for pre-treatment of the mixture being separated in order to increase the service life of the filters.

W artykule omówiono zagadnienia dotyczące przyczepności stwardniałych zaczynów cementowych do pobranych z piaskowca rdzeni skalnych, na których wytwarzany był osad z różnych rodzajów płuczek wiertniczych. Rdzenie z wytworzonym osadem przemywano następnie cieczą przemywającą oraz buforem. Przemyte próbki zalewano zaczynem cementowym, pozostawiając je do związania na okres 2 i 7 dni. W trakcie badań wykorzystywano specjalne stanowisko przeznaczone do wytwarzania osadów i przemywania próbek skalnych. Następnie za pomocą maszyny wytrzymałościowej wyznaczano wartość przyczepności zaczynu cementowego do skały. W badaniach laboratoryjnych stosowano płuczkę z PHPA (polimerowo-potasową) oraz płuczkę glikolową. Używano odpowiednio dobranych cieczy przemywających oraz buforu. W badaniach wykorzystywano cztery rodzaje zaczynów cementowych. Były to zaczyny zawierające nanokomponenty (nano-SiO2 oraz nano-Al2O3), zaczyn z dodatkiem lateksu oraz zaczyn konwencjonalny bez specjalnych dodatków. Spośród przebadanych cieczy przemywających najlepsze połączenie na kontakcie stwardniały zaczyn cementowy–skała piaskowcowa uzyskano po zastosowaniu wodnego roztworu niejonowego surfaktantu z grupy etoksylowanych alkoholi tłuszczowych. Komponenty zaczynów cementowych w postaci nanododatków i lateksu powodują polepszenie parametrów technologicznych zaczynu cementowego (w tym zwiększenie przyczepności do skały). Nanotlenek glinu i krzemu oraz lateks redukują również m.in. odstój wody, czyli tzw. wolną wodę, z zaczynów oraz obniżają filtrację, co ma szczególne znaczenie w przypadku cementowania otworów kierunkowych. Zdecydowana większość badanych próbek cechowała się bardzo wysoką przyczepnością kamienia cementowego do skały. Można to tłumaczyć prawidłowym dobraniem cieczy przemywającej i cieczy buforowej do konkretnego rodzaju płuczki, a następnie użyciem odpowiedniego zaczynu cementowego. Opracowane w ostatnich latach w INiG – PIB ciecze przemywające oraz zaczyny cementowe mogą być wykorzystane w krajowym przemyśle wiertniczym, co powinno przyczynić się do poprawy jakości wiązania zaczynu cementowego z rurą okładzinową i formacją skalną.

» Patellar instability is challenging to address, and although there are many surgical options, proximal patellar realignment (PPR) and medial patellofemoral ligament (MPFL) reconstruction are both used—recently, the MPFL reconstruction has become more popularized.» Both procedures have demonstrated similar recurrent dislocation rates and rates of arthritic progression.» PPR is a cost-efficient procedure using just suture alone as compared with MPFL reconstruction, which uses different grafts and methods of fixation.» PPR has demonstrated durable results, with a lower overall complication rate, much of which is caused by the MPFL reconstruction having unique complications due to fixation methods.» The PPR is a beneficial procedure and should still be considered when dealing with patellar instability.

Reconcile Large Multi-Regional Input-Output databases using Generalized Minimal Residual method and fast computing
Authors: abdaoui abderrazak , Onat Nuri , Kucukvar Murat 
Published: September 2024

Abstract

In the design of multi-regional input-output (Multi-RegionalInput-Output (MRIO)) databases, data has to be reconciled from several sources. This requires looking for an equilibrated MRIO table that fits data from each source. The performances of the current data reconciliation methods, which mostly use RAS-type algorithms, is quite constrained. Furthermore, the mathematical underpinnings of RAS-type algorithms are not fully understood, and they are limited in their ability to handle particular constraints. Some methods, like the Least-Squares and Chebychev, have been shown to have a solid mathematical foundation. Still, they come with extra complexity regarding the number of iterations and computation needs. This paper proposes the integration of the Generalized Minimal Residual Method to reconcile many data sources for the MRIO databases. The comparison of the Generalized MinimalResidual (GMRES)’s convergence with the availability centered inventory model (Availability Centered Inventory Model (ACIM)) method for reconciliation shows its rapidity and robustness. In addition, the results show the low complexity of the GMRES compared to other existing methods.

Abstract

Extrachromosomal circular DNA (ecDNA) have been found in most types of human cancers, and ecDNA incorporating viral genomes has recently been described, specifically in human papillomavirus (HPV)-mediated oropharyngeal cancer (OPC). However, the molecular mechanisms of human-viral hybrid ecDNA (hybrid ecDNA) for carcinogenesis remains elusive.
We characterized the epigenetic status of hybrid ecDNA using HPVOPC cell lines and patient-derived tumor xenografts, identifying HPV oncogenes E6/E7 in hybrid ecDNA were flanked by novel somatic DNA enhancers and HPV L1 enhancers, with strong cis-interaction. Targeting of these enhancers by clustered regularly interspaced short palindromic repeats interference or hybrid ecDNA by bromodomain and extra-terminal inhibitor reduced E6/E7 expression, and significantly inhibited in vitro and/or in vivo growth only in ecDNA(+) models. HPV DNA in hybrid ecDNA structures are associated with novel somatic and HPV enhancers in hybrid ecDNA that drive HPV ongogene expression and carcinogenesis, and can be targeted with ecDNA disrupting therapeutics.

Published: September 2024

Abstract

The surface treatment of iron artefacts requires an application of the proper conservation coating to prevent further corrosion deterioration. Tannate coating is preferred as a conservation agent of iron/steel with the desired black appearance of the surface. In this work the modification of the tannate coating with hydrotalcites to improve conservation ability was studied. Methodology of the surface treatment was developed, and process parameters: hydrotalcite addition, applied layers, immersion time and pH of the stock solution were studied. The treated surface was characterised by various methods e.g. Raman spectroscopy, EDX measurements and electrochemical characterization and the quality of the surface treatment was evaluated with respect to cyclic QUV test. Effect of hydrotalcite addition on quality of the conversion coating was confirmed and explained by incorporation of Al in the coating. Mechanism of the modified conversion coating was proposed.

Abstract

Fatigue is a complex, multi-faceted phenomenon that is particularly common in immune-mediated inflammatory disease and neurodegenerative disease cohorts. Clinical assessment of fatigue relies heavily on patient-reported outcomes (PROs), that provide only the perception aspect of fatigue and poorly capture fluctuations over time. The use of wearable sensors, e.g., inertial measurement units, overcome these drawbacks, by allowing for the assessment of capacity and performance aspects of health through continuous monitoring of daily life activities. However, the relation between daily life activities that are prerequisite for functional independence, such as sit-to-stand and stand-to-sit transitions, and fatigue, is not well established, thus this study aims to quantify the association between kinematic features of sit-to-stand and stand-to-sit transitions and self-reported physical and mental fatigue. Study participants wore an IMU on the lower back for four consecutive weeks, and continued their daily life activities as usual, thereby reporting their physical and mental fatigue four times per day on a 7-point Likert scale via a smartphone application. Sit-to-stand and stand-to-sit transitions were detected using a validated algorithm, and kinematic features were derived from those transitions. The association between the kinematic features and PROs were researched using mixed effects models, with fatigue modelled as the independent variable and the median, 95th and 5th percentiles of the kinematic features from a 2-hour aggregation window centred around the time of administration of a PRO. The results suggested 5th and 95th percentiles of selected kinematic features were associated with fatigue across different disease cohorts. Furthermore, it was hypothesised that with more fatigue standing up is performed with more effort that is needed, whereas with more physical fatigue sitting down is performed with less control of the body movement, i.e., people drop down on their chair or sofa. In conclusion, this study showed the potential of selected kinematic features of sit-to-stand and stand-to-sit movements as intermediate clinical endpoints to reflect aspects of fatigue.
