A Critical Review on PFAS Removal from Water: Removal Mechanism and Future Challenges
Authors: Amen Rabia , Ibrahim Alhassan , Shafqat Waqar , Hassan El Barbary
Published: November 2023

Per and polyfluoroalkyl substances (PFAS) have been extensively employed in a broad range of manufacturing and consumer goods due to their highly persistent nature. PFAS exposure is recognized to pose serious health hazards; therefore, addressing PFAS pollution in water has become a top priority for public health and environmental protection organizations. This review article focuses on the efficiency of different removal techniques (activated carbon, biochar, ion exchange resin, membrane filtration, reverse osmosis, metal-organic frameworks, foam fractionation, ozone fractionation, and destruction techniques) for eliminating different types of short- and long-chain PFAS from water. Hydrophobicity and electrostatic interactions are revealed to be the primary mechanisms for the elimination of PFAS. The efficiency of all techniques to eradicate short-chain PFAS is comparatively lower compared to long-chain PFAS. The destruction techniques are the most efficient but have some drawbacks, including the formation of PFAS precursors and high operational costs. According to the findings from the study, it is anticipated that combined methods will be required to effectively remediate PFAS-contaminated water.

Published: November 2023

This study aims to identify the presence of vaccine hesitancy and the factors that could have determined it in a group of mothers in the postpartum period, with an evaluation of both the level of knowledge and information, as well as the attitudes, perceptions, intentions and sources of information about vaccination. The study was based on a survey—Vaccine Hesitancy Identification Survey—applied in two maternity wards from Bihor County and structured into six subscales (34 items). Based on the answers to the key questions (“Which of the following statements best describes your plans for vaccinating your child?”—item 1 of subscale 4; “Overall, how hesitant do you consider yourself to be about vaccinating your child?”—item 4 of subscale 4), we identified two groups: the group of mothers without hesitant behavior (non-hesitant), called the group pro vaccine (GPV), and the group of mothers with hesitant behavior, called the group non vaccine (GNV). Vaccine hesitancy was identified in our study in 47.28% of the participants (191 of the 404 mothers included). Most of them come from an urban environment (57.59%), have university and post-secondary education (58.64%) and are prim parous (58.64%). The behavior of participants from GNV is influenced by a low level of knowledge and information regarding vaccination and by concerns related to adverse reactions, new vaccines and the number of vaccines administered. Also, this group is characterized by an increased perception of the risks related to vaccination, while the perception of the risks associated with the disease is low. For all subscales, important differences were registered between the two groups in favor of GPV, a group characterized by positive attitudes and perceptions and a better level of knowledge compared to GNV. This study aims to represent a starting point for the organization and running of information campaigns regarding vaccination at the level of Bihor County, especially in areas with low vaccination coverage, where this behavior is identified.

New technological platforms, such as mRNA and adenoviral vector vaccines, have been utilized to develop coronavirus disease 2019 (COVID-19) vaccines. These new modalities enable rapid and flexible vaccine design and cost-effective and swift manufacturing, effectively combating pandemics caused by mutating viruses. Innovation ecosystems, including universities, startups, investors, and governments are crucial for developing these cutting-edge technologies. This review summarizes the research and development trajectory of these vaccine technologies, their investments, and the support surrounding them, in addition to the technological details of each technology. In addition, this study examines the importance of an innovation ecosystem in developing novel technologies, comparing it with the case of Japan, which has lagged behind in COVID-19 vaccine development. It also explores the direction of vaccine development in the post-COVID-19 era.
Spatial and Temporal Variations of the Precipitation Structure in Jiangsu Province from 1960 to 2020 and Its Potential Climate-Driving Factors
Authors: Ren Zikang , Zhao Huarong , Shi Kangming , Yang Guoliang
Published: November 2023

This study investigated the temporal and spatial variations of precipitation duration and intensity in Jiangsu Province from 1960 to 2020 using the IDW spatial interpolation method and Kendall’s tau trend test, based on daily precipitation data collected from 22 meteorological stations. Additionally, a Pearson correlation analysis was conducted to examine the correlations between the occurrence rate and contribution rate of precipitation with different durations and grades, as well as five large-scale climate indices. The results indicated the following trends: (1) An increase in the precipitation duration corresponded to a decrease in the occurrence rates, while the contribution rates initially increased and then decreased. The province was predominantly characterized by 1–3 days of light rainfall, with a higher probability of short-duration heavy rainfall in northern Jiangsu. (2) From 1960 to 2020, most stations experienced decreasing trends in the precipitation duration occurrence and contribution rates, but heavy rainfall increased, suggesting a shift to short-duration heavy precipitation. (3) The Arctic Oscillation (AO) notably negatively correlates with the 9-day occurrence rate of precipitation (9dOR), while it positively correlates significantly with the occurrence rate of moderate rainfall (MROR). The North Atlantic Oscillation (NAO) exhibits a significant positive correlation with the 2-day occurrence rate of precipitation (2dOR) and a notable negative correlation with the 9-day occurrence rate of precipitation (9dOR). The PDO (Pacific Decadal Oscillation) has shown significant positive correlations with the 2-day precipitation occurrence rate (2dOR) and contribution rate (2dCR), a negative correlation with the light rainfall occurrence rate (LROR), and significant positive correlations with both the moderate and heavy rainfall occurrence rates (MROR and HROR, respectively). The AO, NAO, and PDO are potential climate factors that influence changes in the precipitation structure in Jiangsu Province. These research findings offer valuable insights for regional water resource management, flood risk assessment, and predicting future precipitation trends under climate change scenarios.
Geophysical and Geochemical Pilot Study to Characterize the Dam Foundation Rock and Source of Seepage in Part of Pensacola Dam in Oklahoma
Authors: Sanuade Oluseun , Ismail Ahmed
Published: November 2023

Pensacola Dam, operated by the Grand River Dam Authority (GRDA), is a multiple-arch buttress dam constructed in 1940. The dam has little or no existing geophysical reports on the integrity of the dam foundation rock and even less knowledge at depth. Visual inspection indicated evidence of seepage at some arches of the dam. As a pilot study, we conducted a suite of geophysical surveys inside two arches (Arch-16 and Arch-17) and a part of the downstream berm to characterize the dam foundation rock, delineate seepage zones, and identify the most appropriate geophysical methods for temporal monitoring of the dam’s conditions. The geophysical methods included electrical resistivity tomography (ERT), self-potential (SP), multichannel analysis of surface waves (MASW), compressional (P)-wave refraction, and shear (S)-wave reflection. Water samples were collected for geochemical analysis to investigate the source of the seepage flow inside Arch-16. The geophysical results characterized the dam foundation rock into an unsaturated limestone and chert overlying a water-saturated limestone and chert. The ERT profiles indicated that groundwater is rising inside the arches and significantly dropping under the downstream berm, which can be due to the uplift pressure beneath the dam base. Zones of high seepage potential were detected near the buttress walls of the two surveyed arches, which may be related to previous blasting, excavation of the dam foundation, concrete placement, or improper grouting. The geochemical analysis of water samples taken from the artesian wells inside Arch-16 and the Grand Lake revealed different chemical compositions, suggesting that the source of water could be a mixture of groundwater and lake water or lake water interacting with rock and reaching the surface through fractures; however, more sampling and further analysis are required to ascertain the source of the seeps. This study showed that the ERT, SP, and S-wave reflection methods have effectively characterized the dam foundation rock and seepage zones beneath the arches. The study provided a better understanding of the conditions of the dam foundation rock, evaluated the utilized geophysical methods, and determined the optimum geophysical methods that can be used for the characterization and monitoring of the subsurface conditions along the entire length of the dam. In this study, we have demonstrated that the integration of effective geophysical surveys and geochemical analysis yielded optimum results in solving a complex dam safety problem. This strategy promotes the best practice for dam safety investigation.

A Pleasurable Methodology: Joyously Reimagining our Neighbourhoods
Authors: Madagammana Bhaveeka
Published: November 2023

The Tāmaki Makaurau Auckland neighbourhood of Ellerslie has undergone destructive erasures of ecology and indigeneity since colonisation. This is exemplified by the filling with concrete of the sacred subterranean caves, Waiatarua, during the construction of the Ellerslie Racecourse grandstand. This paper argues that this causal act of destruction through architectural procedures, and others geographically similar to it, can be understood as a result of a painful colonial legacy that continues to adversely inform architecture today. In response, a Pleasurable Methodology is proposed as an alternative architectural practice that emotively engages with the immanent whenua of Waiatarua. It speculatively aims to generate neighbourhoods where equality is formed between the vitality and wellbeing of the earth with the wellbeing of the communities that whakapapa and live there. This is crucial to facing the rising inequities of housing, food security and climate facing our cities. As a result of the methodology, experimental drawings are created from an embodied pleasurable engagement between decomposing organic matter as whenua and conventional architectural materials such as wire, paper and clay. This entangled dialogue provokes an emotive neighbourhood where whenua and pleasure fabricate and reimagine a regenerative way of living within our isthmus. This paper’s main findings conclude that by challenging conceptions of land and architecture, we can potentially endeavour to feel and then draw future neighbourhoods where the vitality of whenua is intimately tied to loving communities.
Katamari Kart: A Serious and Hilarious Sub/Urban Game for More Serendipitous, Playful and Friendly Public Art
Authors: Berthelsen Chris , Rachev Rumen , Bonham Alex
Published: November 2023

The article presents the sub/urban game-method Katamari Kart, where people roam industrial and suburban areas collecting waste materials and progressively building a large and mobile public sculpture. This game-method departs from established concepts and practice in neighbourhood improvement as it tries to evade capital expenditure and embraces uncertainty and friction in bringing together various stakeholders, does not aim to look stylish or even be useful, decelerates daily life, promotes self-sufficiency in cultural life, and creates long-term wellbeing through play. That is, it is a degrowth approach to neighbourhood improvement. Rumen Rachev positions the Katamari Kart game-method as an expression of the ‘Kiwi way’ and discusses the role it can play in making our future neighbourhoods more serendipitous, playful and friendly, and a ref lection of the diverse people and things that reside there – all without capital expenditure or the support of the authorities. Finally, Alex Bonham, author of the book Play and the City: How to Create Places and Spaces to Help Us Thrive, discusses the Katamari Kart game-method in the context of adult play, our settler history, keeping up appearances, the Be a Tidy Kiwi campaign, play and wellbeing, and conflicting responses to frugality.

Authors: ÇOKAL Zeynep
Published: November 2023

Amaç ve Önem: Bu çalışmanın amacı, turist ile birebir iletişim halinde olan turist rehberlerinin mesleki yeterliliklerini önem performans analizine göre değerlendirerek mesleki yeterlilikleri hakkında mevcut durumu ortaya koymak, turistler açısından turist rehberlerinin mesleki yeterliliklerine ilişkin önem düzeyleri ile performans düzeylerini karşılaştırmak ve elde edilen verilerden hareketle turist rehberlerine öneride bulunmaktır.

Yöntem: Turist rehberinin mesleki yeterlilikleriyle ilgili beklentileri ve önem verdikleri mesleki yeterlilik unsurları arasındaki farklılıkları belirlemek için 41 maddeden oluşan bir ölçek kullanılmıştır. Bu ölçekte yer alan ifadelerin değerlendirilmesinde Önem Performans Analizi (ÖPA) yöntemi kullanılmıştır. ÖPA, turistlerin rehberlerle ilgili beklentileri ile deneyimledikleri performans arasındaki farkı belirleyerek, mesleki yeterliliklerin önem derecesini anlamak için kullanılan bir yöntemdir. Bu şekilde, çalışmada hem demografik özelliklerin analizi için yüzde ve frekans dağılımlarından yararlanılmış, hem de turistlerin rehberlerle ilgili beklenti ve önem verdikleri unsurların analizi için Önem Performans Analizi kullanılmıştır. Bu yöntemler, katılımcıların görüşlerini ve beklentilerini anlamak ve elde edilen verileri istatistiksel olarak değerlendirmek için kullanılmıştır.

Bulgular: Araştırma sonucuna göre turistlerin, turist rehberinin mesleki yeterliliklerine ilişkin en fazla önem verdikleri yeterlilik “Tur bilgisi”dir. En az önem verdikleri ise yeterlilik ise “Alışveriş imkânı sunma”dır. Turist rehberinin mesleki yeterliliklerini ortaya koyduğu hizmetin performansını değerlendirdiklerinde ise en iyi performansların “tur bilgisi” olduğu, en düşük performansın ise “ekonomi bilgisi” olduğudur. Turist rehberleri bu yeterlilikler ile ilgili olarak katılımcıların verdikleri önemin üzerinde performans sergilemişlerdir. Genel olarak turist rehberlerinin beklenilenden daha fazla bilgiye sahip oldukları ve destinasyona ekonomik katkı sağlayıcı davranışlarda bulunduğu söylenebilir. Tüm bu bulgular turist rehberinin mesleki yeterliliklerini yerine getirdiğini ve yüksek performans sergilediğini göstermektedir.

Özgünlük/Bilimsel Katkı: Araştırma bulguları ışığında Kapadokya Bölgesi’nde hizmet veren turist rehberlerinin mesleki yeterlilik düzeylerinin oldukça yüksek olduğu ve turistler tarafından da performanslarının yüksek olarak algılandığı sonucuna varılmaktadır. Bu sonuç doğrultusunda turist rehberliği mesleğinin önemi ve ulusal düzeyde ne kadar iyi bir şekilde icra edildiği ortaya çıkmaktadır. Literatür incelendiğinde turist rehberinin mesleki yeterliliklerinin önem performans analizine göre değerlendirildiği bir çalışmaya rastlanmamaktadır. Bu da çalışmanın özgünlüğünü ortaya koymaktadır.

Sınırlılıklar: Araştırma Kapadokya Bölgesi’ni turist rehberi eşliğinde ziyaret eden turistler üzerine uygulanmıştır. Bu da araştırmanın sınırlılıklarını oluşturmaktadır.

Authors: Skrebnev V. I. , Serzhan S. L. , Kalugina E. V.
Published: November 2023

The results of tests of materials for hydro-abrasive wear resistance, as well as the erosion values of studied materials, are presented. It has been found that the use of thermoplastic vulcanizates (TPV) as a co-extruded coating of the inner surface of polymer pipe systems can significantly increase the lifetime of slurry pipelines when exposed to hydraulic mixtures, in particular iron ore tailings. In a model test simulating actual operating conditions of the pipeline, it was shown that TPV and thermoplastic polyurethane (TPU) coatings are signifi cantly superior in wear resistance to high-density polyethylene (HDPE) and steel.

En esta serie de Vídeos Didácticos Lingüísticos nos dirigimos a un amplio público de estudiantes de francés desde los niveles principiantes hasta los avanzados (A1-C1). Los contenidos de los vídeos se centran en distintas áreas de dificultad contrastiva en las que se constatan disimetrías fonéticas, gramaticales, léxicas o pragmáticas entre el francés y el español. En este vídeo, se introduce y se define en primer lugar el concepto de falso amigo. Acto seguido, se presentan una serie de ejemplos que buscan ilustrar el concepto anteriormente evocado. Finalmente, se propone a los aprendientes un ejercicio en el que tienen que localizar los falsos amigos en tres frases y justificar su respuesta, es decir, explicar por qué son falsos amigos. La solución estará disponible en el vídeo “Attention, hispanophones! Descubre más sobre… Los falsos amigos en francés”.

El vídeo es idóneo para explicar el concepto de falso amigo (faux-ami), es decir, un término similar en español y en francés, ya sea porque tiene una ortografía o una pronunciación parecida, pero cuyo significado difiere entre ambas lenguas. Por ejemplo, el verbo salir en francés podría confundirse con el verbo español salir, puesto que se escriben igual. Ahora bien, el significado no es mismo entre las dos lenguas, ya que salir en francés quiere decir ‘ensuciar, manchar’.

Solution of 25% and 45% strawberry extract as stain extrinsic cleaning material on heat polymerised acrylic resin plates
Authors: Nurlitasari Dewi Farida , Sugianitri Kadek , Wilaksmi AA Sri
Published: November 2023

Strawberries can be used as a stain remover because they contain ellagic acid which has the potential to make teeth white and eli-minate bad breath. This study examines the effectiveness of strawberry extract as an alternative cleaning agent for stains caused by extrinsic discolouration on heat polymerised acrylic resin (HPAR) plates. Using a pretest and posttest with control group de-sign, 24 RAPP samples were soaked in coffee solution for 7 days. On the 8th day, the colour change was observed using a spec-trophotometer on the HPAR plates. The samples were divided into four groups, namely soaking groups using 25%, 45% straw-berry extract, sodium hypochlorite, and distilled water for 14 days. On the 15th day, the colour change was observed. Data were processed with SPSS using paired t-test and one-way Anova test which showed significant differences in each treat-ment (p<0.05), except for the distilled water group. It was concluded that 25% and 45% strawberry (Fragaria x annanassea) extract solution is effective as an alternative cleaning agent for stains due to extrinsic discolouration on HPAR plates.

The minimum inhibitory concentration test was carried out using the liquid dilution method and the inhibition zone test was carried out using the disc fusion method. The ex-tract concentrations used were 12.5%, 25%, 50%, 75%, and 100%. The results showed a cloudy appearance and no inhibi-tion zone in all tubes containing catfish meat extract tested on Staphylococcus aureus and Candida albicans bacteria. While in the Phorphyromonas gingivalis test, a clear appearance in the tube was found at a concentration of 50%, and an inhibition zone at a concentration of 25%. It is concluded that catfish meat extract has an anti-bacterial effect against P.gingivalis, but has no effect on S.aureus and C.albicans.

Virtual reality (VR) dan augmented reality (AR) are artificial intelligence used for presenting a virtual environment according to reality in real-time. The ability of this technology to adapt human movement, allow it to be used in the medical world as an aid in planning, training and guidance. Although it is known that there is a lot utilization of this technology, its implementation in the field of dentistry, especially oral and maxillofacial surgery is still unknown. Therefore, the purpose of this paper is to provide knowledge about current VR-AR technology, as well as provide information on its utilization in the field of dentistry, particu-larly in the field of oral and maxillofacial surgery. The use of VR-AR in the medical field is felt in the fields of oral and maxil-lofacial surgery. It is concluded that the presence of VR-AR technology requires financial readiness in procuring its compo-ponents. But it is commensurate with the benefits that can be received from this technology, namely can be used for training, as well as navigation during surgery so that time efficiency and minimal invasion during surgery can be achieved.

Removable orthodontic appliances have acrylic resin-based plate components that often result in plaque retention and bacterial build-up, leading to dental and periodontal problems. Several studies have tried adding nanoparticles to acrylic resins to over-come these problems. This review discusses the effect of nanoparticle addition on the antimicrobial properties of orthodontic removable acrylic resin. A literature review was conducted on 10 articles obtained from PubMed, ScienceDirect, and Google Scholar by determining inclusion, exclusion and keyword criteria. Literature search using boolean search based on inclusion criteria obtained data that the addition of various nanoparticle materials such as zinc oxide, titanium dioxide, magnesium oxide produces good antimicrobial properties, especially in the process of inhibiting microbial adhesion. It is concluded that the addi-tion of nanoparticles to acrylic resin orthodontic appliances provides effective antimicrobial properties so that it can be applied clinically to prevent diseases in the oral cavity such as gingivitis and dental caries.

Background: The World Health Organization recommends using a face mask to prevent infection with the coronavirus illness 2019 (COVID-19). Students are often nonchalant about maintaining physical or social distance from their peers, undermining the necessity of wearing a face mask both inside and outside of the classroom. The purpose of this study was to determine the students' knowledge, attitudes, and practices about the use of face masks at Novena University in Ogume, Delta State, Nigeria. Methodology: This was a descriptive cross-sectional study carried out among 400 sampled students. A self-administered questionnaire was used to collect the data while descriptive and inferential statistics were used to analyze the data at a significance level set at p<0.05. Results: About 220(55.0%) of the responders were between the ages of 21-25 years, and 260(65.0%) were females. The majority of responders, 340 (85.0%), had a good understanding of how to utilize a face mask. However, both attitudes towards using face masks 280(70.0%) and face mask usage 340(85.0%) were poor. The following demographic characteristics were shown to be substantially linked with knowledge, attitude, and use of face masks: age, sex, marital status, level of study, and religion at p<0.05. Conclusion: The majority of the respondents had an adequate understanding of how to use a face mask, a negative attitude about using a face mask, and poor practice of using a face mask to prevent COVID-19 infection. The study recommends the need for public health enlightenment campaign and education on the value and correct face mask usage among students in tertiary institutions.

Background: In Saudi Arabia as well as globally, breast cancer is the most common cancer among women. Early diagnosis can lead to a better prognosis, and mammography screening may be an adequate way to get there. Studies on breast cancer and mammography awareness have been conducted in Saudi Arabia. Objectives: The current study set out to assess Saudi Arabian female patients' knowledge, attitudes, and awareness regarding breast cancer and mammography screening. Methods: A thorough search was carried out in October 2023, mostly using PubMed, in compliance with PRISMA criteria. The search was limited to English-language research that looked at the relationship between mammograms and breast cancer. To guarantee the quality and applicability of the evaluated research, certain inclusion and exclusion criteria were developed. Results: A wide spectrum of research from various Saudi Arabian locations was included in the study, with a major focus on female individuals. A discernible pattern indicated a high proportion of individuals with breast cancer and mammography screening. Our study concludes that Saudi women know very little about breast cancer and mmammography in general. Interventions must be put into place in order to combat this ignorance.
