Evaluation of Various Generalized Pareto Probability Distributions for Flood Frequency Analysis
Authors: Anghel Cristian Gabriel , Ilinca Cornel
Published: April 2023

This article analyzes six probability distributions from the Generalized Pareto family, with three, four and five parameters, with the main purpose of identifying other distributions from this family with applicability in flood frequency analysis compared to the distribution already used in the literature from this family such as Generalized Pareto Type II and Wakeby. This analysis is part of a larger and more complex research carried out in the Faculty of Hydrotechnics regarding the elaboration of a norm for flood frequency analysis using the linear moments method. In Romania, the standard method of parameter estimation is the method of ordinary moments, thus the transition from this method to the method of linear moments is desired. All the necessary elements for the distribution use are presented, such as the probability density functions, the complementary cumulative distribution functions, the quantile functions, and the exact and approximate relations for estimating parameters, for both methods of parameter estimation. All these elements are necessary for a proper transition between the two methods, especially since the use of the method of ordinary moments is done by choosing the skewness of the observed data depending on the origin of the maximum flows. A flood frequency analysis case study, using annual maximum and annual exceedance series, was carried out for the Prigor River to numerically present the analyzed distributions. The performance of this distribution is evaluated using a linear moments diagram.

Authors: Hao Shuang , Wörman Anders , Riml Joakim , Bottacin-Busolin Andrea
Published: April 2023

Hydropower is the largest source of renewable energy in the world and currently dominates flexible electricity production capacity. However, climate variations remain major challenges for efficient production planning, especially the annual forecasting of periodically variable inflows and their effects on electricity generation. This study presents a model that assesses the impact of forecast quality on the efficiency of hydropower operations. The model uses ensemble forecasting and stepwise linear optimisation combined with receding horizon control to simulate runoff and the operation of a cascading hydropower system. In the first application, the model framework is applied to the Dalälven River basin in Sweden. The efficiency of hydropower operations is found to depend significantly on the linkage between the representative biannual hydrologic regime and the regime actually realised in a future scenario. The forecasting error decreases when considering periodic hydroclimate fluctuations, such as the dry–wet year variability evident in the runoff in the Dalälven River, which ultimately increases production efficiency by approximately 2% (at its largest), as is shown in scenarios 1 and 2. The corresponding potential hydropower production is found to vary by 80 GWh/year. The reduction in forecasting error when considering biennial periodicity corresponds to a production efficiency improvement of about 0.33% (or 13.2 GWh/year).

Published: April 2023

Compared to other countries in the Middle East and North Africa region, Lebanon is considered the richest in water resources. However, due to inadequate water management, Lebanese water resources are under stress. Previous studies in Lebanon were mainly focused on heavy metals and microbiological analysis. Following the increase in cancer rates in Lebanon, the occurrence of six anticancer drugs estimated to be the most administered in Lebanon was assessed in samples collected from wastewater treatment plants (WWTPs), sewage outfalls, and surface water. Two SPE–LC–MS/MS methods were developed and validated for the detection of the selected anticancer drugs with LOD values ranging between 0.1 and 0.9 ng/L and LOQ values ranging between 0.3 and 2.8 ng/L. Three anticancer drugs were detected using this technique, 5-fluorouracil, methotrexate, and cyclophosphamide, with an overall concentration range of 1 to 305 ng/L. The detection of these drugs in WWTP effluents, sewage outfalls, and rivers confirmed the weaknesses prevailing in the management of wastewater and the treatment technologies adopted by the few operational WWTPs in Lebanon.
Photocatalytic Removal of Ciprofloxacin in Water by Novel Sandwich-like CuFe2O4 on rGO/Halloysite Material: Insights into Kinetics and Intermediate Reactive Radicals
Authors: Ngo Ha-Son , Nguyen Thi-Linh , Tran Ngoc-Tuan , Le Hanh-Chi
Published: April 2023

In this study, the CuFe2O4 on rGO/halloysite material was made in an uncomplicated manner. The catalyst has a sandwich-like shape with a uniform coating of the active phase on the rGO sheets and halloysite tubes. The catalyst’s large specific surface area (130 m2/g) and small band gap energy (1.9 eV) allow it to adsorb photons and photocatalyze organic contaminants effectively. In approximately 1 h of light, the catalyst showed high performance in achieving almost complete conversion in photodegrading CIP for an initial CIP concentration of 20 ppm. A pseudo-first-order rate law was followed by the process, as revealed by the experimental results. In addition, the pH effect and the contribution of intermediate reactive radicals that emerged during the photochemical process were explored. The results indicated that hydroxyl radicals and holes had a major impact on CIP decomposition, suggesting that the addition of these radicals could enhance CIP degradation efficiency at a larger scale. This study also confirmed the superiority of catalysis and photochemical processes in environmental treatments by the neutral pH values.

Pretreatment of raw feed water is an essential step for proper functioning of a reverse osmosis (RO) desalination plant as it minimizes the risk of membrane fouling. Conventional pretreatment methods have drawbacks, such as the potential of biofouling, chemical consumption, and carryover. Non-conventional membrane-based pretreatment technologies have emerged as promising alternatives. The present review focuses on recent advances in MF, UF, and NF membrane pretreatment techniques that have been shown to be effective in preventing fouling as well as having low energy consumption. This review also highlights the advantages and disadvantages of polymeric and ceramic membranes. Hybrid technologies, which combine the benefits of conventional and non-conventional methods or different membranes, are also discussed as a potential solution for effective pretreatment. The literature that has been analyzed reveals the challenges associated with RO pretreatment, including the high cost of conventional pretreatment systems, the difficulty of controlling biofouling, and the production of large volumes of wastewater. To address these challenges, sustainable hybrid strategies for ceramic membrane-based systems in RO pretreatment are proposed. These strategies include a thorough assessment of the source water, removal of a wide range of impurities, and a combination of methods such as adsorption and carbon dioxide with a low amount of antiscalants. Furthermore, the suggestion of incorporating renewable energy sources such as solar or wind power can help reduce the environmental impact of the system. A pilot study is also recommended to overcome the difficulties in scaling ceramic systems from laboratory to industrial scale. The review also emphasizes the importance of conducting an effective assessment to suggest a treatment for the brine if needed before being discharged to the environment. By following this framework, sustainable, energy-efficient, and effective solutions can be recommended for pretreatment in desalination systems, which can have significant implications for water scarcity and environmental sustainability.

Le travail d’historien aboutit presque toujours à instaurer des filiations, à faire apparaître des liens de descendance. C’est l’une des raisons, sans doute, pour lesquelles il produit parfois le goût (la tentation ?) de chercher des ressemblances comme il s’en trouve, au fil des siècles, entre les membres successifs d’une lignée. J’imagine que le débat est classique, chez les spécialistes, et qu’il donne lieu à des prises de position multiples sur les finalités de l’histoire. Puisque le passé, à partir de ce qui reste de lui, et même, plus précisément, à partir de ce que l’on sait en rester, est toujours repéré, reconstruit, par un regard ultérieur, il change évidemment avec la date même de ce regard. La «double historicisation» (historicisation du passé que l’on étudie, historicisation de celui qui l’étudie) constitue vraisemblablement une nécessité méthodologique forte

du travail de l'histoire. L'analyse historique, dans ces conditions, est donc toujours une réévaluation du passé, une transformation des représentations que l’on en a, l’élaboration de figures neuves de l’autrefois.

Published: April 2023

Background (including purposes): Acyclovir (ACV) is a widely-used drug in the prevention and specific treatment of diseases caused by Herpes virus. However, due to its limited solubility and poor permeability, its therapeutic effectiveness is not high. Therefore, improving the transdermal permeability of ACV is necessary to increase the therapeutic effect of the drug for topical administration. Materials and methods: The study investigated the effect of the concentration of gelling agent, and the concentration of Aloe vera (A.vera) on the physico-chemical properties, especially the in vitro and ex vivo permeability by using Franz diffusion cells. Results: The formulation with 5% (w/w) of ACV, 4.5% (w/w) of A.vera, 5% (w/w) of glycerin and 2% (w/w) of HPMC K100M had the physico-chemical properties suitable for topical administration and the best permeability enhancement as compared to other formulations with different concentrations of A.vera, and a commercial cream formulation containing 5% (w/w) of ACV. Conclusion: A.vera in the gel form was successful prepared and applied to increase the permeability of ACV. This A.vera gel has the potential to develop the formulations for transdermal administration
Key words: Acyclovir, Aloe vera, permeability enhancement

Published: April 2023

Background: Nowadays, ceftriaxone is being used widely and its use is less compatible with the current guidelines. The aim of this study was to determine the appropriate use of ceftriaxone. The results may help to find a way to prevent its inappropriate use in the emergency department (ED). Methods: In this observational-analytical study, the patients who were referred to EDs of two teaching hospitals from September 23, 2019, to March 19, 2020, and treated with ceftriaxone were analyzed. The appropriate use of ceftriaxone was determined based on the latest evidence-based literature. Results: Ceftriaxone had been prescribed properly in 156 patients (38.4%; 95% CI, 33.5-42.9%) and its use did not meet logical criteria in the remaining 250 patients (69.6%; 95% CI, 57.1-66.5%). The appropriate use of ceftriaxone was independently related to goal-directed use, level I triage, urinalysis (U/A) indicating urinary tract infection (UTI), and chest radiographic evidence of pneumonia. Conclusion: Our study revealed the inappropriate use of ceftriaxone in teaching medical centers; therefore, further education seems to be necessary in this field.

Authors: Firouzmanesh Melika , Farmany Abbas , Farhadian Maryam , Mollabashi Vahid
Published: April 2023

Background: Plaque accumulation and bond failure are the drawbacks of fixed orthodontic treatment. Titanium dioxide (TiO2 ) could be added to orthodontic composite as an antimicrobial agent, but it may change its mechanical properties. The aim of this study was to evaluate the mechanical properties of orthodontic composite modified by TiO2 nanoparticles (NPs) after 10000 cycles of thermocycling. Methods: Overall, 50 intact human premolars (extracted for orthodontic treatment) were used in this study. The orthodontic composite containing TiO2 NPs (1% wt) was prepared and used for the bonding of brackets. The bracket/tooth shear bond strength (SBS) was measured by using a universal testing machine before and after 10000 cycles of thermocycling at 5 and 55° C (dwell time=30 seconds). Eventually, the obtained data were analyzed by Student’s t test with the Excel software (significance level≤0.05). Results: After thermocycling, the average SBS of TiO2 containing and control group was 11.43±5.18 MPa and 13.46±5.17 MPa, respectively. The difference in the SBS of the two groups after thermocycling was not significant (P=0.7). The SBS of both groups decreased after thermocycling; however, the reduction was lower in the group with TiO2 than in the control group. Conclusions: TiO2 -containing composite can be used as an antimicrobial agent in high risk of caries patients without deteriorating the mechanical properties.

Published: April 2023

Background: Denture stomatitis (DS) due to Candida albicans is a chronic inflammation of mucous membranes that occurs beneath acrylic resin dentures. Various antifungal and disinfecting agents with different formulations are used to treat this condition with different side effects. Recently, the use of herbal medicines has attracted attention in the treatment of medical and dental conditions. The main goal of this study was to evaluate the antifungal efficacy of effervescent tablets containing ginger on complete dentures in patients with oral fungal infections in vitro. Methods: In the present in vitro study, 81 acrylic resin dentures were divided into 3 groups and contaminated with Candida albicans, Candida glabrata, and Candida krusei fungal species, and each group was assigned to 3 groups, then immersed in solutions containing effervescent ginger tables, nystatin (as a positive control group), and distilled water (as a negative control group). The dentures underwent fungal culture procedures at 30-, 60-, and 180-minute intervals. Finally, the study groups were investigated for the presence or absence of fungal colonies. Results: According to the results, the mean fungal colonies in the nystatin group were generally less than that in the ginger tablet group. The antifungal effect of nystatin began earlier than the ginger tablet, (i.e., in the presence of nystatin), and Candida counts diminished to zero after 60 minutes; however, this happened after 180 minutes in the effervescent ginger tablet solution. Conclusions: Although the antifungal effect of nystatin was higher and faster than that of ginger-containing effervescent tablets, if necessary, it is possible to use ginger tablets for a longer time to eliminate fungal contaminants from dentures. Ginger-containing effervescent antifungal tablets require 180 minutes to exert their antifungal effect.

Dumpsites are the most cost-effective and widely used method of waste disposal. However, studies have linked dumpsites to groundwater contamination, necessitating a safety assessment of groundwater sources near dumpsites. The safety of borehole water near the Olusosun dumpsite in Ojota, Lagos, Nigeria, was investigated in this study. Water samples were collected at distances of 100, 200, and 300 m from the dumpsite and subjected to conventional heavy metal analysis and microbiological tests. The average daily intake (ADI) and hazard quotient (HQ) of heavy metals were also estimated. The heavy metal analysis revealed that copper (Cu) and iron (Fe) levels exceeded permissible limits recommended by the World Health Organization (WHO) at the three locations, while manganese (Mn), lead (Pb), and cadmium (Cd) concentrations were within non-permissible levels only at the distances of 100 and 200 m. The concentrations of other heavy metals tested, such as zinc (Zn), nickel (Ni), and chromium (Cr), were within tolerable limits. The ADI of heavy metals at the three locations was within acceptable levels. However, the HQ of Cd in all the locations, as well as Pb at the distance of 100 m and Cr at distances of 100 and 200 m, was greater than the threshold of 1. The microbiological analysis revealed that all the water samples had non-permissible bacteria and coliform counts. The results obtained suggest that the borehole water around the dumpsite is grossly contaminated, with contamination levels increasing significantly (P≤0.05) with closeness to the dumpsite (100>200>300 m). Therefore, there is a need for heavy metal remediation and disinfection of the dumpsite.

Authors: Fundaoğlu Küçükekenci Funda
Published: April 2023

Background. This study investigated the effects of different acidic solutions used as the final irrigation on the push-out bond strength (PBS) of resin-based and bioceramic-based root canal sealers. Methods. 100 single root and canal human incisors were selected and decorated. Root canal shaping was done with ProTaper Next rotary files up to X4 and rinsed with 5 mL of 5.25% NaOCl between each file. Then, teeth were divided into five main groups according to the final irrigation (n=20). Group 1: glycolic acid; Group 2: phosphoric acid; Group 3: citric acid; Group 4: EDTA and group 5: saline. Then, each group was divided into two subgroups according to the canal sealer used (n=10). The groups filled with bioceramic-based sealer (bioserra) were named A, and the groups filled with resin-based sealer (AH Plus) were called B. PBS test was applied to one of the two samples obtained from the coronal third of each root. The data were statistically analyzed using a two-way analysis of variance and Tukey’s HSD test (α=0.05). Results. Statistically, the highest PBS value was obtained in group 2A (4.81±0.03 MPa), which was irrigated with phosphoric acid and filled with bioserra, and the lowest PBS value was obtained in group 5B (1.10±0,03), which was irrigated with saline and filled with AH Plus (P<0.05). There was a statistical difference between all groups except group 1A and group 3A (P<0.05). Conclusion. The bioceramic-based root canal sealer (bioserra) bond strength is superior to resin-based (AH Plus). Phosphoric acid, glycolic acid, and citric acid can be an alternative to EDTA.

Published: April 2023

Background. There are several invasive dental procedures that require local anesthetics. However, its infiltration is usually associated with anxiety and fear, increasing the perception of pain in pediatric patients. For this reason, it is important to evaluate different strategies for its application. We compared the anesthetic effect of the administration of 2% lidocaine with epinephrine 1:80000 non-alkalized at slow speed and alkalized at fast speed to block the inferior alveolar nerve in deciduous molars. Methods. A crossover clinical trial was carried out whose sample consisted of 38 patients between 6-10 years who required bilateral pulp treatment in their first mandibular primary molars. At the first appointment, they received 2% lidocaine with 1:80000 alkalinized epinephrine administered at a fast rate, and at the second appointment, 2% lidocaine with 1:80000 non-alkalized epinephrine administered at a low speed. We evaluated the onset of action, duration of the anesthetic effect, and intensity of pain during its infiltration. Results. We found that non-alkalized lidocaine at slow speed had a shorter onset time of action (57.21±22.21 seconds) and longer duration of effect (170.82±43.75 minutes) compared to administration of alkalinized lidocaine at fast speed (74.03±22.09 seconds, 148.24±36.24 minutes, respectively). There was no difference in the level of pain intensity. Conclusion. In this study, the slow administration of the non-alkalized local anesthetic showed a shorter onset time of action and a longer duration of the anesthetic effect in comparison with the alkalized local anesthetic administered at a rapid rate in the blockade of the inferior alveolar nerve in deciduous molars.

The activation of an Mg acceptor in p-GaN with rapid thermal annealing (RTA) assisted low-temperature supercritical fluid (SCF) treatment (RTA-A-SCF) was investigated. After RTA-A-SCF treatment, the luminescence band of the N vacancy in the PL spectra was significantly suppressed. An evident decrease in H concentration is also observed in secondary ion mass spectrometer measurements, it indicates an obvious decrease of Mg–H complexes in the p-GaN. In addition, the ohmic contacts have been well improved and the hole concentration has increased by an order of magnitude. The activation mechanism of RTA-A-SCF treatment was further analyzed by X-ray photoelectron spectroscopy.
