Influence of Anode Diffusion Layer on the Performance of a Passive Direct Ethanol Fuel Cell
Authors: Ekdharmasuit Panuwat 
Published: June 2024

One of the main challenges with passive direct ethanol fuel cells (DEFCs) is ethanol transport management since the liquid ethanol is supplied to the anode compartment by natural processes including convection and diffusion with a low cell operating condition. The significant layer in the cell is the diffusion layer (DL), which facilitates reactants to reach the anode catalyst layer (CL). In this study, the impact of various DLs fabricated of readily accessible commercial materials on cell performance in passive DEFCs with different ethanol feed concentrations was examined with various in-situ characterization methods. The results demonstrate that the cell with a DL coated by the hydrophobic microporous layer (MPL) yielded the best performance of 0.887 mW·cm-2 at the optimal ethanol feed concentration of 5 M. In conclusion, the benefits of enhancing ethanol mass transfer to the anode CL would outweigh the drawbacks of preventing ethanol crossover to the cathode.
HIGHLIGHTS

The effect of the anode diffusion layer (DL) on passive direct ethanol fuel cell (DEFC) performance was determined
Five different anode DLs fabricated of readily accessible commercial materials were employed
Various characterizations enabled the assessment of each loss affecting the passive DEFC performance
The cell with an anode DL modified with a hydrophobic microporous layer (MPL) exhibited the best cell performance
The optimal ethanol feed concentration of the best cell was found to be 5 M

Abortus: strafrecht of zorg? Argumenten voor en tegen het ‘decriminaliseren’ van abortus provocatus in Nederland
De strafbaarstelling van abortus (art. 296 Sr) (b)lijkt anno 2024 geen vanzelfsprekendheid meer te zijn. Eind 2023 is een voorstel ingediend ter modernisering van de wetgeving over abortus door zwangerschapsafbreking ‘uit het strafrecht’ te halen (Wet abortus is zorg). De bijdrage vormt een inventarisatie van argumenten voor en tegen het decriminaliseren van abortus. We starten met (de ontwikkeling van) het wettelijk kader. Vervolgens gaan we over tot een verkenning van argumenten voor en tegen decriminalisering van abortus en de vraag in hoeverre het hogere recht decriminalisering van abortus toelaat. De bijdrage sluit af met een conclusie waarin we de balans opmaken.

Finite Element Modeling to Predicting Rutting in Flexible Pavements under Overloading
Authors: Aljaleel Zainab M. , Ahmed Nahla Y. , Atemimi Yahya K. A 
Published: June 2024

Road infrastructure is seriously threatened by heavy vehicle overloading, causing substantial damage, particularly rutting. This study uses advanced finite element analysis (FEA) techniques to improve pavement performance prediction. Six models were created using the ABAQUS/CAE program to evaluate the rutting performance of flexible pavement under overloaded conditions. These models simulated the existing pavement design and a proposed design, each subjected to three axle load configurations: single axle-single tire, tandem axle-dual tire, and tridem axle-dual tire. The research includes conducting surveys on traffic volume and axle load, to precisely evaluate the current traffic situation and identify problems associated with overloading. Core extractions enabled a thorough comparison of the existing pavement's thickness, density, and material characteristics with the proposed design. Based on these findings, a new design for a flexible pavement was developed, focusing on enhancing its ability to withstand rutting. The analysis determines that the existing pavement cannot withstand overloading vehicles, necessitating a 6,67 % increase in the thickness of the surface, a 37,5 % increase in the thickness of the binder, a 50 % increase in the thickness of the base, and a 32 % increase in the thickness of the subbase layers. Significantly, these modifications and improvements to material qualities were discovered to effectively decrease rut depth, an important factor in the durability and performance of pavement

Published: June 2024

Los puertos de contenedores de Panamá en la costa del Pacífico están ubicados en la entrada del Canal de Panamá en su lado pacífico. Esta situación supone que todo el tráfico que ingresa al canal o se dirige a las terminales portuarias, comparte el mismo espacio. Esta situación puede provocar congestión y retrasos en la llegada del barco a la terminal. Desde el punto de vista del flete, el tiempo que el barco espera por un slot de escala es redundante en toda la cadena de transporte requerida. Si además existen obstáculos y tráfico no fluido en el lado de tierra (terminal); la cadena de transporte multimodal se verá afectada en términos de estadías y desconexiones.

Este artículo presentará las primeras etapas en el diseño del modelo de desempeño para mejorar la eficiencia del tránsito de carga. A través de un trabajo de campo realizado a través de cuestionarios enviados a los transportistas terrestres, junto con una serie de entrevistas a responsables del transporte y del área marítima. Nos muestran resultados que indican que el tiempo promedio máximo actual que tarda un transportista en cada proceso para poder entregar y/o recoger una carga es de 30 minutos. Esto sugiere que es necesario fortalecer los procesos, para lograr una reducción de tiempos.
Comparative analysis of the yacht marinas' vulnerability to sea level rise by using an integrated vulnerability index
Authors: Bayazit Seyma , Kuleli Tuncay 
Published: June 2024

This study aims to analyse the vulnerability of yacht marinas in Bodrum to sea level rise (SLR) compound impacts using seven spatial physical and eight socio-economic parameters. A new integrated marina vulnerability index (IMVI) was developed as a composition of the physical coastal vulnerability index (PCVI) and non-physical marina vulnerability index (MVI). To determine vulnerability values, coastal vulnerability index approach was used. A geo-database was created using spatial and tabular data collected from different data source. The PCVI parameters were converted to a 1-5 scale by using geographic information systems analysis (GIS) (subset, buffer, slope, reclass, map algebra), and PCVI values were calculated. The MVI parameters were converted to a 1-5 scale by using the natural break classification method, and MVI values were calculated. Both PCVI and MVI results were presented as maps and tabular values using a scale of 1 (Very Low Vulnerability) to 5 (Very High Vulnerability). The results provide comparative vulnerability analyses of seven marinas, using the PCVI and MVI, individually and, their combination with IMVI. The findings showed that the physical vulnerability of marinas was generally higher than their socio-economic vulnerability. While the physically very high vulnerability marinas are Turgutreis, Yalikavak and Ortakent, the marina with very low socio-economic vulnerability is Ortakent. According to IMVI results, Turgutreis, Yalikavak and Milta are the vulnerable marinas both physically and socio-economically. Consequently, this study potentially brings a new perspective to research on SLR-induced climate impacts not only for marinas but also for cargo ports.

Authors: Carvalho Beatriz Carneiro de , Silva Lívia Gabrielly Cruz da , Vasconcellos Neto João Ronaldo Tavares de 
Published: June 2024

Aims: Neglected tropical diseases, such as Visceral Leishmaniasis, affect over 1 billion people in tropical and subtropical regions, with Leishmaniasis being endemic in various parts of the world and causing up to 1 million new cases annually. It is crucial to investigate the decline in hospitalization cases in Feira de Santana and its possible linkage with the COVID-19 pandemic and local socioeconomic factors.
Study Design: An exploratory-descriptive bibliographic study with a qualitative approach.
Place and Duration of Study: Department of Health, Higher Education Unit of Feira de Santana, Feira de Santana (Bahia), during the first semester of 2024.
Methodology: The bibliographic survey was conducted through searches of scientific productions on the proposed theme, from 2018 to 2024. Searches were performed using keywords in Portuguese and English with the Boolean operator "AND". In addition to literature review, the collection of secondary data was conducted by the Department of Health Informatics of the Unified Health System (DATASUS).
Results: The complex interaction among socioeconomic, environmental, and public health factors, exacerbated by the COVID-19 pandemic, impacts the dissemination, underreporting, and control of leishmaniasis, highlighting the urgent need for integrated approaches and strengthening of health systems to effectively address this neglected disease.
Conclusion: Therefore, it is concluded that the main causes may include reductions or delays in notifications, which can lead to difficulties in differentiating diseases with similar clinical presentations and even coinfections.

Molecular Modeling in Peptide and Protein Analysis
Authors: Kuczera Krzysztof 
Published: December 2011

AbstractThis article describes the theoretical background and practical applications of classical molecular mechanics (MM) and molecular dynamics (MD). Following a brief historical outline of molecular modeling, the concept of the molecular potential energy function is introduced and the basic algorithms of MM, namely, energy minimization, normal mode analysis, MD, and Monte Carlo (MC) simulations, are defined. The advantages of molecular modeling methods — speed of calculations and detailed microscopic insight — are described. The shortcomings — approximate nature and difficulties with conformational sampling — are also analyzed. A number of modern approaches aimed at improving the reliability of computer simulations are briefly presented, including advanced energy optimization methods, treatment of long‐range forces, and accelerated conformational exploration. Examples of applications of molecular modeling methods to the study of various aspects of the structure, dynamics, and function of peptides and proteins are presented. A brief exposition of the relationship between molecular modeling and some fundamental experimental techniques, such as X‐ray crystallography, neutron scattering, nuclear magnetic resonance (NMR), and fluorescence and vibrational spectroscopies, is provided. Finally, an outline of future directions of modeling studies is suggested.

Abstract
Over the past 30 years, DNA sequencing evolved from a work‐intensive, low‐throughput, and high‐cost endeavor into an affordable, automated and high‐throughput technique for biological research. Currently, we are experiencing the advent of DNA sequencing technology platforms based not only on the long‐time prevailing biological techniques, but also on multidisciplinary approaches. While current second‐generation technologies rely on massively parallel sequencing of clonally amplified DNA molecules, third‐generation technologies are based on single‐molecule sequencing. A major motivation for the development of new technologies is meeting the challenge to provide sequencing of an entire human genome for less than US$1000; and what seemed almost impossible a decade ago now seems to have become reality. In this review, we give an overview of the currently available sequencing platforms, as well as a preview of promising new technologies that may enter the market in the near future. We discuss the most common biological applications and how high‐throughput sequencing (HTS) has changed and will change the understanding of biological systems.
