Performance evaluation of a semivolatile aerosol dichotomous sampler (SADS) for exposure assessment: impact of design issues
Authors: Rekeb Noredine , Sutter Benjamin , Belut Emmanuel , Géhin Evelyne , Olsen Raymond 
Published: June 2024

Abstract. Aerosols of semivolatile organic compounds (SVOCs) pose significant health risks to workers in various occupational settings. Measuring human exposure to these aerosols requires a separate assessment of the contribution of particles and gases, which is not resolved by existing sampling techniques. Here, we investigate experimentally the performance of a semivolatile aerosol dichotomous sampler (SADS), proposed in previous studies, for sampling monodisperse liquid particles with aerodynamic diameters between 0.15 and 4.5 µm, corresponding to workplace aerosols. The measured sampling performances are compared to their theoretical counterparts computed by computational fluid dynamics. The effects of leakage rate, repeatability of the assembly, imprecision of the actually machined nozzle diameters, and SADS part misalignment are examined. The SADS assembly is found to be easily leaky, but consequences on sampling can be overcome when a prior leak test with a leakage rate below 4 Pa s−1 is passed. Variation of nozzle diameters in the range (−4.5 %, +3.7 %) with respect to nominal values affects marginally (< 3 %) aerosol transmission efficiency, but sampling performance is little reproducible during successive SADS assemblies (CV = 22.1 % for wall losses). Theoretically unpredicted large (40 %–46 %) wall losses are measured for particles larger than 2 µm, located mostly (80 %) on the external walls of the collection nozzle. Assembly repeatability issues and simulations of SADS parts misalignment effect by computational fluid dynamics (CFD) suggest that these undesirable particle deposits are due to the mechanical backlashes of the assembly. Thus, the current design does not guarantee a nozzle misalignment of less than 5 % of the acceleration nozzle diameter, and other important geometric parameters are not further constrained. The promising theoretical sampling performance of the SADS for SVOC aerosols larger than 1 µm thus falls short of expectations due to mechanical design issues that can be improved before possible field use.
The use of MgO–ZnO ceramics to record pressure and temperature conditions in the piston–cylinder apparatus
Authors: Farmer Nicholas , O'Neill Hugh St. C. 
Published: June 2024

Abstract. The factors affecting the calibration of pressure in the piston–cylinder and other solid-media apparatus are so multifaceted and complex as to challenge existing approaches. Here we demonstrate how MgO–ZnO ceramics may be used in piston–cylinder assemblies to routinely record the pressure–temperature conditions experienced by samples in each run. The miscibility gap between rock-salt- and wurtzite-structured phases in the binary system MgO–ZnO is well suited for this purpose as it is capable of recording pressure and/or temperature in situ with a typical sensitivity to pressure of ± 0.02 GPa (1 standard deviation) if temperature is known, or variations in temperature around a sample of ∼ 10 °C assuming pressure is constant. MgO–ZnO ceramics can simply replace the widely used MgO surrounding samples under most conditions, since they are almost as inert chemically as MgO and have similar mechanical properties. As a demonstration, we apply the method to a redetermination of the quartz–coesite univariant phase transition in the piston–cylinder, using different assembly materials, sizes, and pressure–temperature path protocols. Continuous monitoring of piston travel during the entirety of each run helps reveal the differences in behaviour of the apparatus under these variables. We show that several assumptions about the behaviour of the piston–cylinder apparatus are ill-founded, that there may be a discrepancy of ∼ 10 % in pressure between otherwise identical experiments conducted using slightly different experimental protocols, and that the effects of the various options for assembly materials are complex, depending on the pressure–temperature path of the experiment throughout its duration. We have also used the sensitivity of the miscibility gap to temperature to map the temperature distribution in two dimensions surrounding a platinum capsule in a piston–cylinder experiment. The routine inclusion of the ceramic in piston–cylinder assemblies would provide an archive of actual experimental P–T conditions experienced by samples.

Published: June 2024

The will of entrustment (wisayah) is one form of trustee and property management in Islam involving minors who are orphans or mentally or physically disabled because they have no qualifications (al-qasir) to administer property. The management of their properties is the responsibility of the appointed guardian. However, the concept of will of entrustment and its implementation from the syariah perspective are not thoroughly discussed. This confuses the public in managing al-qasir property. Therefore, this study elaborates on the concept of will of entrustment in detail to ensure its implementation is effective and beneficial to al-qasir and assesses the guardian’s responsibilities from the syariah perspective. This study uses a qualitative approach in analyzing and obtaining information from fiqh books, journals, proceedings and selected Islamic Family Law Act and Enactments. The finding of the study shows that the concept of will of entrustment in Islam could protect the rights and property of al-qasir. The result of this study is expected to give the public a clear understanding of how to best manage al-qasir property.
Spinozian Civic Virtues and Epistemic Democracy
Authors: Bustamante Gonzalo , De Brasi Leandro 
Published: June 2024

Abstract
This article rereads Benedict de Spinoza and recent interpretations of him as an epistemic democrat through the prism of contemporary debate on the conditions for deliberation in a democracy. Through a reconstruction of Spinoza's arguments and theories of deliberation and its preconditions, we argue that, for deliberation to produce the benefits Spinoza recognizes, the process must be inclusive, and those deliberating must be both intellectually humble and autonomous. This interpretation is new and diverges from those recently advanced by Justin Steinberg and Sandra Leonie Field. In particular, on our reading, Spinoza's critique of humility does not extend to intellectual humility as it is understood today in political theory. Both autonomy and humility, as epistemologically conceived by political theorists today, can therefore be considered Spinozian civic virtues.

Published: June 2024

The raw natural gas extracted from production wells contains many impurities such as oil, sulphur, carbon dioxide, nitrogen, and other impurities. Among these impurities that must be removed in order to achieve the specifications of the liquid natural gas (LNG) is a water vapor. Because free water causes hydrate formation in transport pipelines and in addition to corrosion when combine with acid gases, resulting in heavy losses in maintenance costs of transport pipelines. For these reasons, natural gas must be dehydrated. The most common methods is Glycol dehydration process, and this process has a good results. In this paper, we have suggested a solvent and simulated it and proof its effectiveness in dissolving the water and dehydration the gas instead of using Tri-ethylene Glycol (TEG). This solvent is Ethylene Glycol Butyl Ether (EGBE), It is used widely as a solvent in surface coatings, and used in metal and household cleaners. It isn’t use in previously natural gas processing. The comparison between glycol types done by Aspen Hysys (glycol package model approach) and according to the dry gas specifications, the simulation results show that: the appropriate flow rate for EG, DEG, TEG, TREG and EGBE are 500 Kgmol/h, 429.5 Kgmol/h, 337.1 Kgmol/h, 80 Kgmol/h and 25.3 Kgmol/h, respectively. Ethylene Glycol Butyl Ether prove a high the efficiency it in dissolving the water with a little flow rate, as well as decrease the energy required for the operation. This paper looks to the use of EGBE as an alternative to TEG for its high efficacy in dissolving water, also significant decrease in the cost of dehydration gas about 98.7 x 109 $/Year].
A multi-step formable transform decomposition method for solving fractional order Riccati equation
Authors: Mtawal Ahmad A H 
Published: June 2024

A multi-step formable transform decomposition method (MFTDM) is suggested in this study to solve the nonlinear fractional-order Riccati problem. It is well understood that a corresponding numerical solution given by the FTDM is only valid for a short period of time. In the case of integer-order systems, however, the MFTDM solutions are more correct and reliable throughout time and are in very good agreement with the exact solutions. The fractional derivative is described in the Caputo sense. The method is tested on prominent examples, and the results show that it is accurate and efficient when compared to other numerical methods.

O presente trabalho aborda o Dadaísmo como uma perspectiva educacional em interlocução com a literatura, considerando-a como mecanismo potencializador de desenvolvimento da escrita criativa e da autoria de professores e estudantes. Nesse contexto, objetiva-se relacionar os pressupostos teóricos básicos do movimento literário Dadaísta com a prática pedagógica de autoria em sala de aula. Para tanto, sob viés metodológico qualitativo, em interlocução com o movimento da vanguarda, analisamos um planejamento didático realizado, no segundo semestre de 2023, com estudantes de mestrado e doutorado de um Programa de Pós-Graduação em Educação de uma universidade pública brasileira. A proposta almejou apresentar uma abordagem lúdica da vanguarda que portou um caráter desconstrutivo do que até então era caracterizada a literatura. Por meio da escrita criativa, potencializada pela orientação disruptiva do movimento dadaísta, trilhamos caminhos de autoria reverberando, nos achados e aglutinados de letras, palavras, sons, frases, sentenças, sentidos produzidos sobre o cotidiano de cada estudante e suas diferentes visões sobre o mundo. Assim, inferimos que atividades dadaístas, na prática pedagógica, potencializam a pluralidade de saberes e fazeres no campo da linguagem, da literatura e da educação, contribuindo para a formação crítica e reflexiva dos estudantes, por meio da autoria no movimento da escrita criativa.

Context.—
The College of American Pathologists (CAP) accreditation requirements for clinical laboratory testing help ensure laboratories implement and maintain systems and processes that are associated with quality. Machine learning (ML)–based models share some features of conventional laboratory testing methods. Accreditation requirements that specifically address clinical laboratories’ use of ML remain in the early stages of development.

Objective.—
To identify relevant CAP accreditation requirements that may be applied to the clinical adoption of ML-based molecular oncology assays, and to provide examples of current and emerging ML applications in molecular oncology testing.

Design.—
CAP accreditation checklists related to molecular pathology and general laboratory practices (Molecular Pathology, All Common and Laboratory General) were reviewed. Examples of checklist requirements that are generally applicable to validation, revalidation, quality management, infrastructure, and analytical procedures of ML-based molecular oncology assays were summarized. Instances of ML use in molecular oncology testing were assessed from literature review.

Results.—
Components of the general CAP accreditation framework that exist for traditional molecular oncology assay validation and maintenance are also relevant for implementing ML-based tests in a clinical laboratory. Current and emerging applications of ML in molecular oncology testing include DNA methylation profiling for central nervous system tumor classification, variant calling, microsatellite instability testing, mutational signature analysis, and variant prediction from histopathology images.

Conclusions.—
Currently, much of the ML activity in molecular oncology is within early clinical implementation. Despite specific considerations that apply to the adoption of ML-based methods, existing CAP requirements can serve as general guidelines for the clinical implementation of ML-based assays in molecular oncology testing.
