Bioleaching Assisting Phytoextraction of Metals from Contaminated Soil: An Overview
Authors: Kurniawan Setyo Budi 
Published: November 2024

Human activities such as mining, industrial operations and waste management can lead to soil pollution by heavy metals including chromium, cadmium, mercury, lead and arsenic. These contaminants cause harm both to humans and the ecosystems where they are found. Of all the previously used techniques, phytoremediation is the most promising one for cleaning up heavy metal-contaminated soils. Phytoremediation refers to a technique where plants use roots for absorbing, storing and immobilizing soil contaminants while also removing them. Bioleaching is a method which uses microorganisms to dissolve metals that have been shown to facilitate phytoextraction in increasing the availability of metals. It is anticipated that research advancements and technological innovations will make it more efficient and appropriate. Root absorption is increased by bioleaching through modification of rhizosphere thus making it more bioavailable for plant uptake. Plant-bacterial interactions are proven to speed up the remediation rates. Both processes can help clear off pollutants from the soil environment. However, further research is needed to find and improve the best strains of microorganisms, assess long-term soil impacts and control massive influxes of bacteria. The combination of bioleaching and phytoextraction offers a reliable and efficient system for removing metals from polluted soils.

Published: November 2024

The main objective of this work is to investigate numerically double-diffusive mixed convection flow in a channel filled with a hybrid nanofluid of Cu-Al2O3 in a porous media. It is considered that the cavity's left wall is continuously heated. The fluid flow enters the channel at low concentration and temperature. This work has been looked into two cases: Case 1, where it is supposed that the left wall cavity has high concentrations, and Case 2, where it is expected that the right wall cavity has high concentrations. The cavity's remaining walls are impermeable and thermally insulated. Non-dimension governing equations are solved with the finite element method. Parameters effects of Reynolds number(10≤Re≤100), Richardson number (2≤Ri≤10), Darcy number (Da=10-2,10-4), Lewis number (1≤Le≤5), buoyancy ratio, N=1, the solid volume fraction (ϕ=0.02), and Prandtl number (Pr=6.2). The results show that increasing Reynolds, Richardson, and Darcy numbers increases the average Nusselt while it decreases by increasing Lewis number. In addition, Sherwood numbers increase with increasing Reynolds, Lewis, and Darcy numbers while they decrease with Richardson numbers for both cases. When the Reynolds number increases from 10 to 50 at (Da=10-4) and (Ri =10), the Nusselt number increases by 102%, while the Sherwood number decreases to 72%.

Published: November 2024

Based on WHO estimates, the unintended pregnancy rate in Indonesia is 40/1,000 women aged 15-49 years. PKBI clinic recorded 210 cases of unintended pregnancy from 2022 to 2024. These cases pose significant risks to maternal and child health. The high incidence of these cases necessitates the provision of high-quality services by health facilities. This is crucial to enhance patient satisfaction and improve service access. The objective of this study is to give an overview of the quality services evaluation for unintended pregnancy at PKBI Clinic. This study is a descriptive study using secondary data from the PKBI clinic based on monthly patient visits from 2022 to 2024. The analysis uses a Run Chart and Control Chart. The results of the Run Chart analysis indicate the presence of common causes that remain under system control, whereas further analysis using Control Charts reveals the presence of special causes. These special causes are associated with patient surges at certain times and the impact of health education programs. However, to anticipate patient surges, the PKBI clinic is still lacking in human resources. This study concludes that Control Charts are more sensitive in detecting special causes due to the presence of control limits that can identify out-of-control data and detect small changes. The evaluation of service quality for unintended pregnancies at the PKBI clinic demonstrates good quality, but a lack of human resources can reduce this quality. Therefore, there is a need for additional staff, training, and better management of work schedules.

Introduction. The production of solid dosage forms from hygroscopic substances is a complex technological task. The addition of hygroscopic substances into a polymer matrix allows to reduce their moisture absorption capacity.Aim. Reducing the hygroscopicity of deliquescent substances and obtaining sustained release solid dosage forms by using solid dispersion systems.Materials and methods. Substance: DEAE; excipients: Kollidon® VA 64, Soluplus®, PEG 1500, PEG 6000, PEG 8000, Poloxamer Kolliphor® P 188 and Kolliphor® P 407; reagents: hydrochloric acid, sodium dihydrogen phosphate, potassium hydrogen phosphate. The melt of the components was obtained on a twin-screw laboratory extruder and cast into silicone molds. The resulting solid dosage forms were studied for disintegration in three environments corresponding to the sections of the human gastrointestinal tract.Results and discussion. The active pharmaceutical substance DEAE is characterized as deliquescent substance. The introduction of DEAE into PEG-polymer matrices made it possible to reduce the hygroscopicity of solid dosage forms in the form of bars. The introduction of solubilizers into the melt made it possible to obtain bars with the appropriate organoleptic properties. The release of DEAE from bear- or toroid-shaped bars occurs on average 29–47 % faster than from heart-shaped bars.Conclusion. Compositions based on Soluplus® and Kolliphor® P 407 have proven promising for further development of tiles containing DEAE. In order to create tiles with a slow release, it is recommended to use heart-shaped forms, as they have a smaller surface area.

The Scottish Diaspora Framework: A New Paradigm of Scottishness?
Authors: Stewart Leith Murray , Sim Duncan 
Published: November 2024

It is generally accepted that members of diasporas tend to maintain a connection with and identification with their home nation. This is often expressed as a hyphenated identity and may be maintained through generations; later generations may become involved in family research to reactivate ties to the homeland. The Scottish diaspora is a classic example of such an identity but, although that sense of identity with the homeland is expressed by the diaspora, it is not clear if this is reciprocated by the homeland, whose attitude to diaspora members may not necessarily be an inclusive one. Contemporary Scotland, a nation with a very large diaspora, provides us with an opportunity to examine this closely. In this paper, we explore attitudes towards the Scottish diaspora and how things have changed, with a Scottish Government proactively connecting with its diaspora. In particular, we explore their recent diaspora policy framework document, which has begun to redefine ‘Scottishness’ to be a more inclusive and transnational identity.

Published: November 2024

Esta investigación fue conocer cuánto tiempo los participantes pasan conectados al internet, cuál es el dispositivo que más utilizan y en qué actividades pasan el tiempo mientras utilizan el internet. Se evaluó si existen correlaciones entre la Escala de Uso Problemático del Internet (EUPI-6) y los datos sociodemográficos y los cuestionarios Ansiedad Generalizada (GAD-7) y Cuestionario de Salud del Paciente (PHQ-8). También, se exploró si existen diferencias entre el género de la muestra en función a los instrumentos. Por último, se exploró si la EUPI-6 sirve como variable moderadora/mediadora de las demás variables. La muestra estuvo compuesta mayormente por mujeres (80.6%). Se utilizó un diseño no experimental transversal exploratorio-descriptivo. Los hallazgos principales indican que el 30% de los participantes consumen de dos a tres horas en el internet, y existe una correlación significativa entre las escalas. También se observó que hubo diferencias entre el género y las puntuaciones de las escalas. Por último, se observó que el uso problemático del internet no modera la relación entre la ansiedad y la depresión en la muestra de participantes. Sin embargo, sí media parcialmente la relación entre ansiedad y depresión en los participantes. Esperamos que esta investigación abra paso a explorar este fenómeno y sus efectos más adelante en los niños y adolescentes, además, de que sirva para que los profesionales de la salud mental lo incluyan en sus procesos de evaluación, utilizando la escala EUPI-6, con la creación de protocolos y política pública con el fin de maximizar la calidad de vida y un uso óptimo del internet.

ContextRecent insights into type 2 inflammation have led to the development of monoclonal antibody therapies for severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). Despite add-on therapy with a monoclonal antibody, some individuals remain uncontrolled in terms of upper and/or lower airway symptoms, prompting an exploration of the efficacy of combining biological therapies and their impact on inflammatory pathways.ObjectivesIn this article, we present a distinctive case of a patient with CRSwNP, severe eosinophilic asthma, and uncontrolled upper airway symptoms, who experienced substantial clinical and local inflammatory improvements through dual monoclonal antibody therapy.MethodsWe provide a detailed case description and analysis of the patient's nasal tissue and secretions to gain insights into the local nasal inflammation under this unique therapeutic approach.ResultsThe addition of an anti-IL-4Rα antibody led to an improvement in upper airway symptoms and a reduction in both eosinophilic and neutrophilic inflammation, despite prior anti-IL-5 therapy. These effects were consistently observed in both polyp tissue and nasal secretions.ConclusionOur patient, with CRSwNP, severe eosinophilic asthma, and uncontrolled upper airway symptoms, experienced substantial improvement with dual monoclonal antibody therapy, without major complications or side effects.
