Investigating dye adsorption: The role of surface-modified montmorillonite nanoclay in kinetics, isotherms, and thermodynamics
Authors: Alruwais Raja Saad 
Published: December 2024

Abstract
The study presents a straightforward, eco-friendly method for removing toxic dyes, such as methylene blue (MB) and acid red (AR), from aqueous solutions through solid-phase extraction using adsorption on surface-modified montmorillonite nanoclay. The nanoclay, containing 25–30 wt% methyl dihydroxyethyl hydrogenated tallow ammonium (MM-MDH nanoclay), functions as the environmentally benign adsorbent. The physical properties of MM-MDH nanoclay were characterized utilizing scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and surface area analysis. Optimal conditions for dye removal, including solution pH, nanoclay dosage, contact time, solution temperature, and ionic strength, were systematically investigated. Experimental results demonstrated that MM-MDH nanoclay effectively removed the majority of dyes within 90 min. Isotherm data indicated an adsorption capacity of 34.33 mg/g for AR dye and 20.19 mg/g for MB dye under optimal conditions. The adsorption process was analyzed kinetically and thermodynamically, revealing that the pseudo-second-order kinetic model accurately described the adsorption behavior. Thermodynamic analysis confirmed that the process was spontaneous and exothermic for AR dye and spontaneous and endothermic for MB dye. The effectiveness of MM-MDH nanoclay was further validated by removing dyes from three different real samples, demonstrating high performance in dye removal over four consecutive cycles.

Published: December 2024

Abstract
The machine learning methods are hereby proposed to predict the amount of Carbon Monoxide (CO) and Carbon Dioxide (CO₂) emissions in a gasification process, which is one of the most important enabling technologies for carbon-containing materials, such as coal, biomass, and waste toward producing end products of worth, such as syngas, hydrogen, and synthetic fuels. In an attempt to support efforts for improving the emission prediction-a key criterion for enhancing efficiency and further, the environmental performance of gasification-two new advanced algorithms are being applied for the optimization of the model of a random forest: the Jellyfish Search Optimizer (JSO) and Sooty Tern Optimization Algorithm (STOA). The tuned RFJS (RF+JSO) was the best of these configurations, providing the least RMSE of 0.593 on test data and the highest R
2 on validation of 0.983, proving to be most effective for the prediction of emissions. This goes to attest that the model RFJS would be a strong tool in real-time-based carbon emissions reduction due to its effectiveness in dealing with major implications from environmental monitoring to regulation and further into sustainable energy production.

Abstract

310When incentives fail to encourage enough owners to make their buildings climate-proof, the State has to impose obligations to retrofit buildings if climate targets are to be reached. This contribution examines whether the State can employ obligations based upon agreement with third-party effect, to enforce higher energy-efficiency standards for buildings and an improved energy mix. It presents and compares the responses to two cases from eleven European jurisdictions. It shows that the majority of examined jurisdictions will allow for the State to impose positive obligations with third-party effect through a burden registered in favour of the State or a property right for the buyer. Only Dutch law would be likely to invalidate the obligation because the obligation circumvents public-law safeguards. A minority of the examined jurisdictions would not allow for a burden with positive obligations as its main content.311

Abstract
In this work, a strategy of in situ 3D hierarchical porous HKUST-1/cellulose/chitosan (CSGA/HKUST-1) composite aerogels were synthesized using ethylene glycol diglycidyl ether (EGDE) as a cross-linking agent. The effect of EGDE on CSGA/HKUST-1 and the adsorption of tetracycline (TC) was investigated: the composite aerogel (CSGA) was produced by the ring-opening reaction of the epoxy group of EGDE in alkaline solution. The chemical structure of CSGA/HKUST-1 composite aerogel was characterized by FT-IR, XRD and XPS.49.33 % mass loading of CSGA1/HKUST-1 was achieved and N2 adsorption and desorption experiment showed the BET specific surface area reached 694.514 m2 g−1. SEM observed the CSGA/HKUST-1 composite aerogel pores were filled with a large number of octahedral HKUST-1 crystal particles. CSGA/HKUST-1 composite aerogel has excellent tetracycline adsorption capacity (285.7 mg g−1), and the removal efficiency remained at 92.7 % after five cycles of adsorption–desorption. The pseudo-second-order kinetic model and Langmuir model adsorption mechanism was successfully concluded. This study can provide ideas for in situ synthesis of MOFs on 3D composite aerogel to prepare adsorption materials, improve the mass loading rate of MOFs and prevent MOFs from falling off, etc., and enrich the application of MOFs materials in the treatment of antibiotic pollutants.

Abstract
The uptake of Eu, Th, U, and Pu by Korean granite and biotite gneiss was investigated in a series of batch experiments. Experiments were conducted under well-defined redox conditions, i.e., oxidizing (air), mildly reducing (Ar-atmosphere and buffered with hydroquinone, pe + pH ≈ 8–9), and strongly reducing (Ar-atmosphere and buffered with Na2S2O4, pe + pH ≈ 0.5–3). Radionuclide concentration, pH and E
h were systematically monitored up to t ≤ 113 days after the addition of the radionuclide. The natural content of Eu, Th and U in pristine granite and biotite gneiss materials was quantified by means of alkaline fusion. Eu exhibited moderate sorption on biotite gneiss displaying higher distribution ratios (R
d) compared to granite. This observation was possibly explained by the affinity of Ln(III)/An(III) towards biotite mineral absent in the investigated granite material. Strong sorption was observed for Th, U, and Pu in reducing systems where the predominance of the +IV oxidation state is expected. For these three systems, the strength of the uptake follows the order R
d(Pu(IV)) > R
d(U(IV)) > R
d(Th(IV)), consistent with the hydrolysis strength of the corresponding aquo-ions. A significantly weaker sorption was observed for U and Pu under oxidizing conditions, although R
d values are manifestly higher for Pu than U. Thermodynamic calculations for the oxidizing conditions predicted the predominance of U(VI) and Pu(V)/Pu(IV), explaining observed differences in retention under oxidizing conditions. These results contribute to a quantitative description and a better understanding of the retention of redox-sensitive radionuclides in crystalline host rocks. Emphasis is placed on the importance of utilizing both redox-stable probes (e.g., Eu, Th) and redox-sensitive actinides (e.g., U, Pu), as well as well-defined redox conditions for accurate predictions of radionuclide retention.
Maximum Magnitude of Induced Earthquakes in Rate and State Friction Framework
Authors: Im Kyungjae , Avouac Jean-Philippe 
Published: December 2024

Abstract
We analyze the evolution of the rupture radius and maximum magnitude (Mmax) of injection-induced earthquakes on faults obeying rates and state friction. We define the radii of two different slip modes, aseismic (Ra) and seismic slip (Rs), and derive an expression for maximum magnitude evolution. If the flow rate is sufficiently high, the seismic moment grows with the scaled injection volume, Qt/wS, as M∼Cf(Qt/wS)3/2, in which Cf depends on the initial stress level, S is storage coefficient, and w is the thickness of the reservoir. These findings are confirmed using numerical simulations conducted with varied initial states. The simulations show that Rs behaves as a rupture arrest radius and Ra behaves as the minimum possible radius of aseismic creep at a given injection volume. The Mmax evolution curve can be steeper if the fault is slightly critically stressed. A high-flow rate results in frequent seismic events, starting at relatively low-injected volume, which helps track the evolution of Mmax, providing a way to anticipate the risk of a large event. Conversely, a low-flow rate allows for a larger volume injection without seismic events but may lead to sudden large events without precursory events.

Published: December 2024

: Congenital heart disease refers to any anatomical defect in the heart or major blood vessels present in children at birth. CHD (congenital heart disease) occurs in round about 1% of live births in developed countries. In developing countries due to poor resources, delayed diagnosis and surgery for CHD leads to a vicious cycle of congestive heart failure and respiratory infections, resulting in a high prevalence of preoperative malnutrition in patients with CHD. The incidence of congenital heart disease at birth is variable, incidence figures use to range between 5-8/1000 live births before the introduction of echocardiography but due to better diagnosis in today’s era many more milder forms are being detected, so the current estimates range from 8-12/1000 live births.: To assess the nutritional status in patients with CHD using clinical evaluation, anthropometry.: It is a cross-sectional observational stud. In our study a total of 75 cases of congenital heart disease were examined in a period of 18 months: Out of 75 patients 56 (74.66%) were &#60;=5years and male predominance were seen. Most of the patient were having Acyanotic CHD: That there are multiple factors that are responsible for malnutrition in children with CHD including, poor socioeconomic strata, already poor health conditions in the general population, recurrent hospitalizations and recurrent lower respiratory tract infections.

Published: December 2024

The aim of this review is to evaluate the clinical outcomes of flapless extraction of impacted mandibular third molars compared to traditional flap-based techniques, with a focus on patient satisfaction, complication rates, and overall surgical efficiency. The extraction of impacted mandibular third molars (wisdom teeth) is a common procedure in oral and maxillofacial surgery, traditionally performed using a flap-based technique. While this method provides clear access to the impacted tooth, it is often associated with significant postoperative morbidity, such as pain, swelling, and extended recovery time. Recent innovations have introduced flapless extraction as a minimally invasive alternative, aiming to minimize tissue trauma and preserve periosteal integrity. This technique, however, presents its own set of challenges, including limited visibility and technical demands.This review analyzes the current literature on flapless extraction techniques, drawing from retrospective studies, randomized controlled trials, and clinical case reports. The data include comparisons of postoperative outcomes between flapless and traditional methods, emphasizing factors such as operative time, postoperative discomfort, and the frequency of complications. Findings indicate that flapless extraction generally results in reduced postoperative pain, swelling, and faster recovery times compared to traditional flap-based techniques. Patients who undergo flapless extraction report higher satisfaction due to less postoperative discomfort and a quicker return to normal function. However, the technique poses challenges in cases of deeply impacted teeth, where the lack of a flap may hinder complete access and increase the risk of complications. Flapless extraction represents a promising evolution in the surgical removal of impacted mandibular third molars, offering several advantages over traditional methods, particularly in reducing postoperative morbidity. However, the technique requires precise surgical skill and is not suitable for all cases. Careful case selection is crucial, and continued research is needed to further validate its efficacy and safety in complex scenarios.

Objective – This study examined librarians’ perceptions of tribalism/ethnicity and favouritism practices and the perceived effect on job satisfaction and service delivery in federal university libraries in Southern Nigeria. The study was aimed at observing whether or not librarians perceive that their senior library managers engage in tribalism/ethnicity and favouritism practices; discerning the extent to which they are perceived to be engaging in tribalism/ethnicity and favouritism practices; ascertaining how the perceived tribalism/ethnicity and favouritism practices can affect job satisfaction of librarians and service delivery by librarians in federal university libraries in Southern Nigeria.
Methods – This study used a descriptive survey research design. The total population for this study comprised 296 librarians who were below the rank of senior library manager from 18 federal university libraries in the southern region of Nigeria. A structured questionnaire was used for data collection. The data collected for this study were analyzed using simple percentage/frequency counts and weighted mean.
Results – This study found that librarians in university libraries in Southern Nigeria believe that senior library managers engage in tribalism/ethnicity and favouritism practices and that the extent of these practices is very high. These librarians clearly have strong concerns that the practise of tribalism/ethnicity and favouritism in libraries can have negative effects on librarians’ job satisfaction and can lead to poor service delivery.
Conclusion – It is glaring from this study that tribalism and favouritism practices by senior library managers are perceived to be prevalent in university libraries in Southern Nigeria, significantly impacting librarians' job satisfaction. This negative workplace dynamic can hinder effective service delivery, ultimately affecting user experience and the library's role in education. Addressing these biases is crucial, as promoting fairness and inclusivity can enhance job satisfaction, improve staff morale, and lead to higher quality library services for all patrons.
Un agitateur philosophique en politique? Considérations sur l’écriture politique de Fichte a partir de sa rencontre avec Machiavel
Authors: Bazzan Marco Rampazzo 
Published: December 2024

Au fil des années, l’essai sur Machiavel que Fichte publié dans la revue patriotique Vesta en 1807 est devenu une véritable énigme pour les interprètes, non seulement par son contenu, mais surtout par l'importance qui lui a été attribué pour l'évolution de la pensée politique de son auteur. Au cours des cinquante dernières années, la discussion sur ce texte a été monopolisée par la querelle autour de la « machiavélisation » de Fichte. La thèse que nous défendons dans cet article est que l’impact du dialogue que Fichte instaure avec Machiavel se joue moins dans un tournant de sa pensée de Fichte que dans la l’élaboration d’une écriture politique entre 1807 et 1813.

Background: One of the most important complications of the wound is tissue infection. One of the most common causes of tissue infections is microorganisms such as Staphylococcus. This research investigates the impact of argan oil and polyhexanide on the healing process in wounds with tissue loss infected with Staphylococcus aureus (S. aureus). Methods: The study involved 45 male mice, with 10 mm skin incisions made on their backs under general anaesthesia to create wounds. After 24 hours, an S. aureus (ATCC) suspension was applied to the scars. Wound cultures were collected from each mouse 48 hours later and this was repeated every 48 hours until cultures confirmed S. aureus infection. Treatment commenced once S. aureus growth was detected. The mice were randomly assigned to three groups: a control group (wound created, but no treatment applied), an argan group (1 mL of argan oil administered to the wound via syringe), and a polyhexanide group (1 mL of polyhexanide administered similarly). The wound diameters and clinical symptoms were monitored daily. On the 7th and 14th days, tissue samples were taken from the sacrificed mice for histopathological examination. Result: Based on clinical and histopathological observations, both argan oil and polyhexanide were found to be effective in treating S. aureus-infected wounds with tissue loss in mice. However, argan oil demonstrated a superior therapeutic potential compared to polyhexanide.

Published: December 2024

Background: Patient Safety Incidents (PSI) in hospitals are adverse events that need to be reported for effective identification and risk management, aiming to prevent reoccurrence of incidents. However, not all incidents are documented, as evidenced by the discrepancy in the number of phlebitis reported by employees as well as Infection IPCLN at three hospitals.
Aims: Provide recommendations to improve employee Personal Attitude towards reporting PSI at three hospitals owned by Company A.
Methods: The method adopted was a cross-sectional research design; data were collected from three hospitals owned by company A and tested using multiple logistic regression statistics tests. Data on Phlebitis reported from January to July 2018 at three hospitals owned by Company A was used. Furthermore,135 respondents were taken from the service installations of the three hospitals. The Lameshow formula and proportional random sampling are applied to determine the sample.
Results: The variables of error orientation (p = 0.001; β = 0.349), behavioral belief (p = 0.008; β = 0.234), and perceived behavioral control (p = 0.003; β = 0.222) had a positive and significant effect on the personal attitude of employees reporting PSI.
Conclusion: Two approaches were recommended to improve the personal attitude of employees in reporting PSI.

Background: HATI is an implementation trial aimed at improving HIV care and treatment, including through SMS reminders.
Aims: This study aimed to estimate the cost and analyze the outcomes of providing SMS Reminders within the HATI program in different settings.
Methods: Data were analyzed using a micro-costing approach from providers' and health systems' perspectives. Subjects were divided into intervention and control groups for outcome analysis, with adherence as the outcome indicator.
Results: From a provider's perspective, the highest cost was incurred in primary health care (PHC) clinics, while the lowest was in hospital clinics, most likely due to a much higher volume of SMS sent from hospitals. Costs from the health system perspective were more than two times higher than those from the provider perspective, as they included costs borne by HATI management and intervention setup. In one year, the number of patients with >95% adherent visits was higher in the intervention group than the control group, although visits decreased over time in both groups. The highest number of patients with >95% adherent visits was found in PHC clinics, while the lowest was in hospital clinics.
Conclusion: SMS reminders can be expensive initially due to setup and program costs. However, they become cheaper once they are embedded into the existing system. Further studies are necessary to determine better site options for scaling up SMS reminder intervention and to study the declining adherence rate in all clinics.
