The saturation equation - an analytical expression for partial saturation during wicking flow in paper microfluidic channels
Authors: Verma Satvik , Toley Bhushan J.
Published: January 2024

The design and fabrication of paper based microfluidic devices is critically dependent on modelling fluid flow through porous paper membranes. A commonly observed phenomenon is partial saturation, i.e., regions of the paper membrane not being filled completely due to pores of different sizes. The most comprehensive model till date of partial saturation during wicking flow in paper is the Richard’s equation. However, the nonlinear nature of this equation and the requirement for numerical solvers for its solution make it largely inaccessible to the paper microfluidics and lateral flow assay community. Moreover, the parameters used in Richard’s equation often need to be tweaked (or assumed) to match experimental data. This necessitates the need for a simple and appropriate model of partial saturation in paper membranes, easily usable by the wider research community. In the current work, we present an approach to model paper membranes as a bundle of parallel capillaries whose radii follow a two parameter log normal distribution. Application of the Washburn equation to the bundle provides a distribution of fluid fronts, which can be used to calculate saturation. Using this approach, we developed the first analytical expression for spatiotemporal variation of saturation in 1D wicking flow. Experimentally obtained data for spatiotemporal saturation for four different paper materials were fit to this analytical model to obtain parameters for each material. Results obtained from this analytical model match both experimental data as well as numerical results obtained from the Richards equation model well. The availability of an analytical expression for partial saturation in wicking flow promises to significantly increase access to such modelling among the wider research community.

Published: January 2024

Multi-resonance thermally activated delayed fluorescence (MR-TADF) materials are considered a class of organic materials with exceptional electronic and optical properties, which make them promising for the applications in organic light-emitting diodes (OLEDs). However, the steric repulsion from the spatially-close hydrogens would twist the multi-resonance skeletons to cause the potential spectral broadening issues. Herein, pyridine and pyrimidine as aromatic-heterocyclic-core are introduced to stiffen the MR framework and minimize the emission spectral broadening by an intramolecular locking strategy. Planarizing the molecular skeleton is achieved due to enhancement of intramolecular interactions (hydrogen bonds) and alleviating the hydrogen steric repulsion. In addition, as a first multiple resonance material with heteroatoms-core, the introduction of pyridine and pyrimidine not only maintains the conventional MR properties of the emitters, but also endows the emitters with tunable emission spectra. Thanks to the overall superior properties brought by the hydrogen‐bonds promoted molecular rigidity, our proof-of-concept molecules, Py-BN and Pm-BN, exhibit deep-blue TADF emission with ultra-narrow full width at half maximum (FWHM) of 14 and 13 nm and Commission Internationale de L’Eclairage (CIE) coordinates of (0.16, 0.03) and (0.16, 0.04), respectively. The OLED developed using them as the emitters demonstrate electroluminescence FWHM of 21 and 24 nm and achieve a high external quantum efficiencies (EQEs) of 15.8% and 5.8%, respectively.

The study examined the levels of selected heavy metal in sediments and their bioaccumulation in catfish (Oreochromis niloticus) and Tomatos (Lycopersium escalentum) from selected unreclaimed mining pits used for irrigation and fish farming in Bukuru town, Jos south Local Government Area “L.G.A” Plateau State. Five (5) unreclaimed ponds were purposively selected; sediment, fish and tomato samples were collected from January to September, with January to March representing dry season and April to September as rainy season. Thirty-two (32) water samples were collected across the study area, while six (6) samples of fish and tomato were collected, three (3) for each season in addition to two controls sampled for different seasons. Samples were analyzed for Cd, Mn, Hg, Cu, Ni, Pb, Ur and Zn. All the heavy metal parameters except Zn, exceeded levels observed at control point as well as maximum permissible limits in the rainy season. Comparison of mean seasonal levels of heavy metals in sediment samples with control, revealed statistical difference at ρ < 0.05, d = 0.007. Similar pattern was observed for the dry season at ρ > 0.05, d = 0.008, an indication that the level of heavy metals presence in sediment samples from unreclaimed mining pits is statistically higher than levels at control point, irrespective of season. Similar results were obtained for Catfish in both seasons (ρ < 0.05, d = 0.006 and ρ < 0.05, d = 0.02) and Tomatoes (ρ < 0.05, d = 0.003 and ρ < 0.05, d = 0.04). These sites should be urgently reclaimed using approved reclamation techniques to eradicate the adverse health impact of consumption of the fruits, animal protein and vegetables cultivated at the sites.

Published: January 2024

In an era marked by escalating environmental concerns and the pressing need for sustainable practices, this paper delves into the transformative potential of decarbonisation in enhancing sustainable procurement practices, with a specific focus on the U.S. context. The study commences with a comprehensive overview of the prevailing procurement practices in the U.S., elucidating their environmental ramifications, particularly in terms of carbon emissions. The discourse then transitions to the broader implications of decarbonisation on a global scale, highlighting its multifaceted benefits beyond mere carbon reduction. Central to the paper’s narrative is the exploration of how decarbonisation can catalyse sustainable procurement. By integrating decarbonisation strategies into procurement processes, entities can mitigate their environmental footprint, realise long-term economic advantages, foster innovation, and fortify stakeholder relationships. However, this metamorphosis lacks challenges, ranging from organisational inertia and economic considerations to stakeholder apprehensions. The paper furnishes a blueprint for policymakers and industry leaders, guiding them through sustainable procurement’s intricacies and spotlighting its potential boons and inherent challenges. The study offers tangible exemplars of sustainable procurement’s potential through real-world case studies, illustrating how diverse entities can effectuate meaningful change. The paper concludes with a call to action for stakeholders, emphasising the collective effort required to transition towards sustainable procurement practices. This study underscores the pivotal role of sustainable procurement, underpinned by decarbonisation, in steering the U.S. and, by extension, the global community, towards a sustainable and prosperous future.

Published: January 2024

In the Qanfouda region, west of the city of Benghazi, this study sought to evaluate the contamination of groundwater wells in residences. The purpose of the study was to determine the extent of groundwater access and the effects that solid waste leachate has on it in the city’s surrounding areas, as well as to evaluate the WQI of the well water. To assess the quality, samples were taken from 8 domestic wells in the area. 11 quality indicators were employed for drinking purposes. Odor, color, pH, soluble salts group, sodium, cadmium, lead, chrome, mercury, total number of bacteria, and coliform bacteria were the tests that were being studied. It also revealed that the water samples used for the study contained lead, cadmium, and sodium as well as a total amount of bacteria and coliform bacteria. These analyses were done in the water and food analysis facilities of the Arab Medical University. And that the Al-Marous village wells*, which have a lead value of 0.017 ppm, have the highest level of lead. Similar to lead, the area opposite the dump had the greatest quantity of cadmium, which was 0.013 ppm. Additionally, a sample taken in the area opposite a dump had the highest concentration of the element sodium. and its concentration was 215.070 ppm. The Qanfouda sample, which was taken in the opposite direction of the landfill to the left of the landfill, likewise contained a total of bacteria and coliform bacteria, at a concentration of (69, 16 colonies / ml). Additionally, the color and smell of the Qanfudah sample, which is located across from the dump and to the left of it, are unsatisfactory, and the concentration of dissolved salts is beyond what is permissible in all samples. The findings show that none of the studied samples’ well water fell within the parameters that Libya’s national drinking water specification allows. released in 2020 by the National Center for Standardization and Standards. Gravimetric water quality index (WQI) was utilized.

Published: January 2024

Structural interpretation and characterization of Assa-field in Northern Niger Delta was done to map the primary structures responsible for hydrocarbon entrapment and closures that are favorable for the accumulation of hydrocarbon as well as to indicate areas for hydrocarbon exploration in the field. The method used for this research involved delineation of lithology, identification of reservoir, interpretation of horizon and fault to generate structural maps of the subsurface. Depth and time structure maps were generated to show more detailed structure of the field. Three major horizons (sand 1, sand 2, and sand 3) were mapped based on uniqueness and clarity of their features. Major faults were delineated from the 3-D seismic section. The appearance of these faults in the field is a sign of possible hydrocarbon accumulation. The knowledge from the results of this study can be applied in exploration and production to identify hydrocarbon trapping potential of a field and volumetric evaluation of fluid in a field.

Reduction to the pole (RTP) is a magnetic anomaly data processing filter to remove the influence of the magnetic inclination angle. This filter is needed because of the magnetic dipole nature which complicates the interpretation process. The research aims to explore andesite rocks through the application of RTP to the local magnetic anomalies data in Kutasari District, Purbalingga Regency, Indonesia. The research procedures include data acquisition, processing, modeling, and interpretation. The 2D-modeling results on the local magnetic anomalies data have produced three layers of rock. Layer with a susceptibility value of 0.00291 cgs is interpreted as vesicular andesitic rocks, layer with a susceptibility value of 0.02307 cgs is interpreted as massive andesitic rocks, meanwhile layer with a susceptibility value of 0.00721 cgs is interpreted as undifferentiated volcanic rocks. The results showed that the west to northwest part of the study area is the most prospective area containing andesite rocks.

Neurodevelopmental disorders with intellectual disability (ND/ID) are a heterogeneous group of diseases driving lifelong deficits in cognition and behavior with no definitive cure. X-linked intellectual disability disorder 105 (XLID105, #300984; OMIM) is a ND/ID driven by hemizygous variants in theUSP27Xgene encoding a protein deubiquitylase with a role in cell proliferation and neural development. Currently, only four genetically diagnosed individuals from two unrelated families have been described with limited clinical data. Furthermore, the mechanisms underlying the disorder are unknown. Here, we report 10 new XLID105 individuals from nine families and determine the impact of gene variants on USP27X protein function. Using a combination of clinical genetics, bioinformatics, biochemical, and cell biology approaches, we determined that XLID105 variants alter USP27X protein biology via distinct mechanisms including changes in developmentally relevant protein–protein interactions and deubiquitylating activity. Our data better define the phenotypic spectrum of XLID105 and suggest that XLID105 is driven by USP27X functional disruption. Understanding the pathogenic mechanisms of XLID105 variants will provide molecular insight into USP27X biology and may create the potential for therapy development.

Background and objectives: Substance misuse is a growing global health problem with particular relevance to university students. Despite this being a significant health problem among an important age group, there is a need for more data on university students in the Middle East. In this study, we aim to assess the prevalence of substance misuse among university students in 3 universities in Jordan to provide up-to-date data. Methodology: This is a descriptive cross-sectional study. Participants were recruited from three governmental universities in Jordan. An online multiple-choice questionnaire was distributed via QR code, and SPSS version 25.0 was used to analyze the gathered data. Results: A total of 1184 participants were recruited, consisting of 729 (61.6%) female and 455 (38.4%) male participants. From the total sample, the lifetime prevalence of illegal substance misuse was 11.8% (n=140), from which the most misused substance reported was sleeping drugs, including benzodiazepine 45% (n=63). Of our total sample, 38.8% (n=453) for smoking tobacco and 6.2% (n=73) for alcohol consumption. Conclusion: Substance misuse among university students was high compared to the general population’s prevalence, and it is believed to be underestimated. The results of this study that capture substance misuse prevalence and the identification of associated factors provide up-to-date data that is potentially informative for further analyses and useful to establish awareness campaigns that aim to enhance health status and the ultimate quality of life among young adults.

Authors: Almualim Anwar
Published: January 2024

In this paper, we are interested in providing an analytic solution for cooperative investment risk. We reformulate cooperative investment risk by writing dual representations for each risk preference (Coherent risk measure). Finding an analytic solution for this problem for both cases individual and cooperative investment by using dual representation for each risk preference has a strong effect on the financial market. In addition, we formulate a problem that covers the risk minimization with an expected return maximization problem with risk constraint, for the general case of an arbitrary joint distribution for the asset return under certain conditions and assuming that all coherent risk measure is continuous from below. Thus, the optimal portfolio is written as the optimal Lagrange multiplier associated with an equality-constrained dual problem. Furthermore, a unique equilibrium allocation as a fair optimal allocation solution in terms of equilibrium price density function for each agent is also shown.

Realizar o monitoramento da variabilidade da precipitação é essencial para o planejamento socioambiental de uma região ou município. Com isso, a pesquisa teve como objetivo analisar o Índice de Anomalia de Chuva (IAC) e a tendência de precipitação anual e dos meses do período chuvoso para o município de Petrolina-PE. Os dados mensais de precipitação foram da série histórica de 1991 a 2021, obtidos por meio do banco de dados do Instituto Nacional de Meteorologia (INMET). Para compreender a variabilidade da precipitação nos anos e nos meses do período chuvoso foi aplicado o método do IAC que distingue os anos com precipitação acima e abaixo da média por meio de classes pré-estabelecidas. Assim, na análise anual do estudo foi possível verificar três anos com anomalias extremamente positivas (1995, 2004, 2009) e dois com anomalias extremamente negativas (2012, 2017). Enquanto na escala mensal, janeiro se destaca como mês com mais anomalias negativas e com a maior anomalia positiva observada no ano de 2004. Além disso, foi possível observar o aumento de anomalias negativas nos últimos anos na escala mensal e anual. No entanto, a análise de tendência linear demonstrou que apesar da maior quantidade de anos secos, o mês de abril apresenta tendência de aumento nos acumulados de precipitação.

O estudo de séries históricas de precipitação é vital para o entendimento da dinâmica hidrológica de uma região, bem como a maneira em que essa interage com as dinâmicas socioeconômicas e espaciais. A precipitação pluvial é o principal meio de recargas dos aquíferos, influenciando na irrigação, acesso à água, estrutura energética, entre outros. Entretanto, é comum encontrar falhas de precipitação em séries históricas, decorrentes de erros de digitação e codificação, pontos de coleta descalibrados e erros em geral no processo de coleta e armazenamento desses dados. Para tanto, recorreu-se a aplicação da correlação de Pearson entre valores fornecidos pela ferramenta Earth Nullschool e as informações de precipitação registrados pela Plataforma de Coleta de Dados (PCD), Alto da Brasileira situada na zona norte do município de Recife, Pernambuco, de responsabilidade da Agência Pernambucana de Águas e Clima (Apac). Dessa forma, buscou-se averiguar a viabilidade do uso dos dados fornecidos pela plataforma para o preenchimento de falha de precipitação em séries históricas, entre outras aplicabilidades técnico-científicas. Assim, o objetivo deste trabalho consiste em averiguar a credibilidade dos dados de precipitação fornecidos pela plataforma Earth Nullschool para Recife, com a finalidade de utilizar ferramentas adicionais no campo do preenchimento de falhas.

This Actio pauliana is actually a lawsuit that substantively attempts to confirm that the debtor's legal actions are declared legally invalid if they harm the creditor. In bankruptcy law, actio pauliana is an important instrument so that substantive justice, especially for creditors, can be implemented optimally. This research aims to analyze the substantive justice aspects of actio pauliana in the field of bankruptcy law. This research is normative legal research by prioritizing conceptual and statutory approaches. The research results confirm that the essence of actio pauliana in bankruptcy disputes is viewed from the aspect of substantive justice, namely that it is aimed at protecting creditor rights, especially when there are debtor legal actions that can harm creditors. Apart from that, Actio Pauliana also emphasizes the restitutive aspect as per the substantive justice concept, namely being able to declare the debtor's actions to have no legal force if the action is detrimental to the debtor and reduces the number of bankruptcy debts as has been determined. In its development, the actio pauliana lawsuit in bankruptcy actually represents the fairness aspect as a manifestation of substantive justice so that in the future the actio pauliana lawsuit will not only represent factual losses, but also include potential losses that directly harm creditors and can be proven fairly and properly
