Assessment and Appraisal of Morning Peak Time Urban Road Traffic Noise at Selected Locations of Major Arterial Roads of Surat City, India
Authors: Ranpise Ramesh B. , Tandel B.N.
Published: January 2022

Urban traffic noise is emerging as a crucial problem in the 21st century. Variation in the level of noise from urban traffic causes several health-related issues. This study demonstrates the noise assessment and appraisal of morning peak time urban road traffic noise at selected locations of major arterial roads of Surat city. The noise is compared against the norms and standards given by the noise pollution (Regulation and Control) Rules, 2000. MoEF&CC has published the Ambient Air Quality Standards in respect of noise under Rule 3(1) and Rule 4(1) as per Schedule in the annexe. In this research work, noise levels were measured at four different locations from Athwa line chowk to Dumas Road of Surat city. Traffic count has been done by calculating the numbers of two wheelers, three-wheelers, four-wheelers, and heavy vehicles (bus & truck). The A-weighted sound level was 78.9 dB(A) near the urban road, which exceeds the standard value recommended by CPCB. The maximum equivalent noise level was 114.9dB at Sushrut hospital, while the minimum was 46.1 dB at Keval chowk. Finally, the study indicates an increment in noise levels with an increment in the count of vehicles. The factors causing the increased noise levels are traffic flow, horn honking, lane indiscipline, heterogeneous traffic condition, morning rush, etc.

Authors: Montecchiari Gabriele , Bulian Gabriele , Gallina Paolo
Published: January 2022

The topic of evacuation analysis plays an important role in the maritime field, because of its natural link to safety and also because of relevant SOLAS requirements. In this context, this paper focuses on the description, testing and validation of an agent-based mathematical model. As primary goal, the model has been developed targeting a use in evacuation simulations using immersive virtual reality, also with the possibility of real-time human participation. At the same time, the model is suitable also for standard evacuation simulations. The model has been developed starting from existing social force models and introducing a series of improvements, modifications, new modelling, and adaptations. The model is described in detail, providing and discussing all adopted parameters. The choice of a game engine as development environment is also discussed, highlighting benefits and limitations. Results from IMO test cases, validations using experimental data, and comparisons with FDS+Evac are presented. A more realistic test case, relevant to the maritime field, with a two-cabin-deck geometry is also presented, together with corresponding simulation results. Particular attention is paid to the post-processing and reporting of the results from Monte Carlo simulations, in order to properly reflect, quantify and emphasize the underlying aleatory uncertainty.

Authors: Teixeira Antonio L. , Salem Haitham , Martins Lais B. , Gonzales Mitzi M. , Seshadri Sudha , Suchting Robert
Published: January 2022

Background: Apathy is among the most frequent neuropsychiatric syndromes in Alzheimer’s disease (AD). Objective: To determine the prevalence of apathy and the associated clinical and laboratorial parameters (focus on inflammatory biomarkers) in patients with dementia enrolled at the Texas Alzheimer’s Research and Care Consortium (TARCC) study. Methods: This is a cross-sectional analysis of TARCC baseline. Participants were evaluated through different clinical tools, including the Mini-Mental State Examination (MMSE) and the Lawton-Brody Instrumental Activities of Daily Life (IADL)/Physical Self-Maintenance Scale (PSMS). Apathy was defined by a positive response to the respective item in the Neuropsychiatric Inventory–Questionnaire applied to caregivers. Serum levels of 16 biomarkers were determined by HumanMap multiplex immunoassay. Comparisons between apathy versus non-apathy groups were carried out with non-parametric tests. Logistic regression and the least absolute shrinkage and selection operator (LASSO) were used to separately model apathy as a function of each biomarker, adjusted for the potential confounders. Results: From 1,319 patients with AD (M/F: 579/740, mean age ± SD: 75.3 ± 8.4), 373 (28.3%) exhibited apathy. When categorized according to the presence of apathy, the groups had significant differences in sex, diabetes diagnosis, and tobacco use. The apathy group also had worse cognitive performance and daily functioning than the non-apathy group as assessed, respectively, by MMSE and IADL/PSMS. Higher levels of interleukin-6, interleukin-10, and leptin were associated with higher odds of apathy. Conclusion: Apathy is associated with cognitive and functional status in AD. The association between apathy and peripheral inflammatory mediators deserves further investigation.
Multivariate Assessment of Lipoxidative Metabolites, Trace Biometals, and Antioxidant and Detoxifying Activities in the Cerebrospinal Fluid Define a Fingerprint of Preclinical Stages of Alzheimer’s Disease
Authors: Mesa-Herrera Fátima , Marín Raquel , Torrealba Eduardo , Díaz Mario
Published: January 2022

Background: There exists considerable interest in the identification of molecular traits during early stages of Alzheimer’s disease (AD). Mild cognitive impairment (MCI) is considered the closest prodromal stage of AD, and to develop gradually from earlier stages although not always progresses to AD. Classical cerebrospinal fluid (CSF) AD biomarkers, amyloid-β peptides and tau/p-tau proteins, have been measured in prodromal stages yet results are heterogeneous and far from conclusive. Therefore, there exists a pressing need to identify a neurochemical signature for prodromal stages and to predict which cases might progress to AD. Objective: Exploring potential CSF biomarkers related to brain oxidative and inorganic biochemistry during prodromal stages of the disease. Methods: We have analyzed CSF levels of lipoxidative markers (MDA and 8-isoF2α), biometals (Cu, Zn, Se, Mn, and Fe), iron-transport protein transferrin (TFER), antioxidant enzymes (SOD and GPx4), detoxifying enzymes (GST and BuChE), as well as classical amyloid-β and total and phosphorylated tau, in cognitively healthy controls, patients with MCI, and subjects exhibiting subjective memory complaints (SMC). Results: Inter-group differences for several variables exhibit differentiable trends along the HC ⟶ SMC ⟶ MCI sequence. More interestingly, the combination of Se, Cu, Zn, SOD, TFER, and GST variables allow differentiable fingerprints for control subjects and each prodromal stage. Further, multivariate scores correlate positively with neurocognitive In-Out test, hence with both episodic memory decline and prediction to dementia. Conclusion: We conclude that changes in the CSF biochemistry related to brain oxidative defense and neurometallomics might provide more powerful and accurate diagnostic tools in preclinical stages of AD.

Published: January 2022

Background: Despite the important associations among sleep, Alzheimer’s disease (AD), subcortical structures, and the cerebellum, structural and functional magnetic resonance imaging (MRI) with regard to these regions and sleep on patients in AD trajectory are scarce. Objective: This study aimed to evaluate the influence of prolonged sleep latency on the structural and functional alterations in the subcortical and cerebellar neural correlates in amyloid-β positive amnestic mild cognitive impairment patients (Aβ+aMCI). Methods: A total of 60 patients with aMCI who were identified as amyloid positive ([18F] flutemetamol+) were recruited in the study, 24 patients with normal sleep latency (aMCI-n) and 36 patients prolonged sleep latency (aMCI-p). Cortical thickness and volumes between the two groups were compared. Volumetric analyses were implemented on the brainstem, thalamus, and hippocampus. Subcortical and cerebellar resting state functional connectivity (FC) differences were measured between the both groups through seed-to-voxel analysis. Additionally, group x Aβ interactive effects on FC values were tested with a general linear model. Result: There was a significantly decreased brainstem volume in aMCI-p subjects. We observed a significant reduction of the locus coeruleus (LC) FC with frontal, temporal, insular cortices, hippocampus, and left thalamic FC with occipital cortex. Moreover, the LC FC with occipital cortex and left hippocampal FC with frontal cortex were increased in aMCI-p subjects. In addition, there was a statistically significant group by regional standardized uptake value ratio interactions discovered in cerebro-cerebellar networks. Conclusion: The aforementioned findings suggest that prolonged sleep latency may be a detrimental factor in compromising structural and functional correlates of subcortical structures and the cerebellum, which may accelerate AD pathophysiology.

Background:

Parkinson’s disease (PD) is associated with various non-motor symptoms, including cognitive deterioration.

Objective:

Here, we used data from the DEMPARK/LANDSCAPE cohort to describe the association between progression of cognitive profiles and the PD motor phenotypes: postural instability and gait disorder (PIGD), tremor-dominant (TR-D), and not-determined (ND).

Methods:

Demographic, clinical, and neuropsychological six-year longitudinal data of 711 PD-patients were included (age: M = 67.57; 67.4% males). We computed z-transformed composite scores for a priori defined cognitive domains. Analyses were controlled for age, gender, education, and disease duration. To minimize missing data and drop-outs, three-year follow-up data of 442 PD-patients was assessed with regard to the specific role of motor phenotype on cognitive decline using linear mixed modelling (age: M = 66.10; 68.6% males).

Results:

Our study showed that in the course of the disease motor symptoms increased while MMSE and PANDA remained stable in all subgroups. After three-year follow-up, significant decline of overall cognitive performance for PIGD-patients were present and we found differences for motor phenotypes in attention ( β= –0.08, SE = 0.003, p < 0.006) and memory functions showing that PIGD-patients deteriorate per months by –0.006 compared to the ND-group (SE = 0.003, p = 0.046). Furthermore, PIGD-patients experienced more often difficulties in daily living.

Conclusion:

Over a period of three years, we identified distinct neuropsychological progression patterns with respect to different PD motor phenotypes, with early executive deficits yielding to a more amnestic profile in the later course. Here, in particular PIGD-patients worsened over time compared to TR-D and ND-patients, highlighting the greater risk of dementia for this motor phenotype.

The alpha-synuclein gene promoter (SNCA-Rep1) is associated with Parkinson’s disease (PD), but its relationship with performance across individual cognitive domains in early PD is unknown. This study aims to investigate Rep1 polymorphism and longitudinal change in cognition in early PD. In this longitudinal study, Rep1 allele lengths (“long” and “short”) were determined in 204 early PD patients. All participants underwent annual neuropsychological assessments and followed up for 3 years. Linear-mixed model was performed to investigate the association of Rep1 status and longitudinal change in individual cognitive domains. At 3 years, significant decline in executive function was observed in long Rep1 allele carriers vs short allele carriers, controlling for potential confounders. This is the first longitudinal study demonstrating that long Rep1 allele carriers are at higher risk for executive dysfunction in early PD.

We studied the main physicochemical features of removing of arsenate from contaminated waters utilizing stabilized nanoscale iron. An inorganic kaolinite matrix was used for stabilization. The structure of adsorbents was studied using some physicochemical methods (X-ray powder diffraction and the low-temperature N2 adsorption-desorption method). It was found that the efficiency of the removal of arsenic (V) ions depends on the weight ratio of iron nanopowder to kaolinite, whereas it does not depend on the pH of the water systems in a wide range. Kinetics data were analyzed using pseudo-first-order and pseudo-second-order models. It was stated that the removal of arsenic by iron-containing composites based on kaolinite occurs relatively rapid. The adsorption kinetic was appropriately described by the pseudo-second-order model, indicating the high affinity of arsenates with the surface of the iron-containing nanocomposite. The results demonstrated that the obtained materials have a much higher sorption capacity to As(V) ions than natural silicates. The Langmuir and Freundlich isotherm equations provided good fittings for the experimental sorption data. It was shown that the sorbents based on stabilized nanoscale iron effectively remove toxic arsenic ions from contaminated water.

Published: January 2022

The adsorption of oligomeric peroxide of sebacic acid and benzoyl peroxide on aerosils and magnesium oxide is studied. The parameters of the adsorption processes are determined. It is shown that the adsorption occurs via formation of hydrogen bonds between surface OH-groups of adsorbents and peroxide groups. The adsorption of benzoyl peroxide on the surface of aerosils and magnesium oxide is low. The thermal decomposition of oligomeric peroxide of sebacic acid and benzoyl peroxide in the presence of aerosil is investigated. The thermal decomposition of oligomeric peroxide of sebacic acid in the presence of aerosils is faster than in a homogeneous system. The corresponding activation energy increases as the aerosil content in the system decreases. In contrast to oligomeric peroxide of sebacic acid, aerosils has no effect on the thermal decomposition rate of the benzoyl peroxide. The polymerization of styrene in the presence of aerosil leads to the formation of a mineral-polymer composite. An increase in aerosil content in the polymerization system leads to a decrease in the rate of polymerization of styrene.
Volatility Spillover between Stock Returns and Oil Prices during the Covid-19 Pandemic in ASEAN
Authors: Alexandri Mohammad Benny , Supriyanto Supriyanto
Published: January 2022

This study points to increase global monetary integration as a result of rising volatility spillovers. As a result, analyzing volatility spillovers for international areas that expand and improve through the usage of inventory returns and oil prices is critical. The EGARCH model is used to explore the Volatility Spillovers of oil agencies in five ASEAN international areas during the Covid-19 Pandemic. To assess the interrelationships of the ASEAN stock index as well as the path of volatility, data were acquired from five global sites with very large volatility spillovers, namely Indonesia, Malaysia, Singapore, Thailand, and Vietnam. The findings show that this search is critical for ASEAN traders as well as Filipinos. Furthermore, because accurate forecasting of volatility spillover in global equity markets is required to reduce portfolio risk, this search has a substantial and viable significance.
PROBLEMS IN USING ICHNOFACIES FOR DEPOSITIONAL ENVIRONMENT INTERPRETATION CASE STUDY: THE CISAAR FORMATION, SUNGAI CISAAR, SUMEDANG DISTRICT, WEST JAVA, INDONESIA
Authors: Rizal Yan , ⠀ Aswan , Fifariz Reynaldy , Mulia Adityan
Published: January 2022

Although numerous researchers have used trace fossils method to determine depositional environment, this method is still considered less robust. This is due to the finding of several similar trace fossils in two or more diverse environments, leading to irrelevancy in environmental interpretation. Therefore, we conducted this study in order to verify how powerful the trace fossil analysis is, by applying this method to interpret the depositional environment of the Cisaar Formation in the Cihanyir Tonggoh area, Sumedang Regency, West Java. We combined trace fossil study with foraminiferal assemblage analysis and vertical succession of related sedimentary units. For this study, 19 rock samples that have been collected from outcrop along 16 m traverse and 14 m measured stratigraphic sections were examined.The result of the study shows that shallow marine trace fossils which were developed at the edge of the shelf, were transported into the basin by gravitational mass flow and re-deposited as deep marine turbidites. Trace fossils were generally found in sandstones, while planktonic foraminifers were found in claystones-sandstones interbeds. This study concludes that to avoid inconsistency in the interpretation of the depositional environment, performing trace fossils method must be integrated with other methods, e.g. analysis of lithofacies and biofacies.
Assistenza infermieristica per paziente con piede diabetico
Authors: Cunha Amanda Priscilla da
Published: January 2022

Introduzione: Il piede diabetico chiamato anche da uno stato fisiopatologico sfaccettato è caratterizzato da lesioni che derivano dai piedi della persona con diabete senza un trattamento adeguato e cure specifiche. Si stima che l’incidenza dell’ulcera del piede diabetico raggiunga il 6,3% dei pazienti diabetici e la sua prevalenza si avvicini al 10% e le persone con basso status socioeconomico sono le maggiori vittime. Alla luce di queste evidenze, il lavoro si basa sulla seguente domanda problematica: quale cura sviluppano gli infermieri nei pazienti con piedi diabetici? Obiettivo generale: Evidenziare la cura del piede diabetico correlata alla pratica degli infermieri. Metodologia: Una revisione integrativa è stata condotta nel Database bibliografico specializzato in infermieristica (BDENF), nella letteratura latinoamericana e caraibica nelle scienze della salute (LILACS) e nella Scientific Electronic Library Online (SCIELO) e che ha portato a sette articoli. Risultati: Gli studi hanno mostrato come la cura degli infermieri con educazione alla salute del piede diabetico, formazione continua e permanente, tecniche di valutazione al piede diabetico che comportano esami fisici e auto-cura dei pazienti con piedi diabetici. È rafforzato il fatto che questa cura dovrebbe essere eseguita in via prioritaria dagli infermieri, poiché gli infermieri hanno un’assistenza specifica e qualificata al paziente nelle loro principali attribuzioni. Conclusione: Si conclude, quindi, che lo studio ha identificato diverse forme di assistenza fornite dagli infermieri e che tutte queste forme sono importanti per la continuità del trattamento e la prevenzione delle complicanze, tuttavia, spetta all’infermiere essere un professionista che valorizza la qualità delle proprie cure sulla base di concetti teorici che portano a una formazione frequente.

Escuela y conflicto. Aportaciones al estado del conocimiento
Authors:   Universidad de Guadalajara, Rojo Zarate María Fernanda
Published: January 2022

Los centros escolares como instituciones socializadoras básicas enfrentan coti-dianamente situaciones de incompatibilidad y diferencia. Este artículo revisa el estado del fenómeno conflictivo en la escuela, con el propósito de evaluar el de-sarrollo académico que ha tenido este tema en los últimos años y trazar nuevas líneas de abordaje e investigación. El trabajo se divide en tres ejes: clima escolar, la escuela ante el conflicto y programas de resolución de conflictos. Se advierte que, como involucrados en el conflicto escolar, las investigaciones revisadas con-sideran mayormente a alumnos y docentes, dejando fuera a directivos y padres de familia. Por otra parte, la experiencia en la aplicación de programas de reso-lución pacífica de conflictos en otras latitudes sirve para la creación de planes y programas formales de intervención con una metodología probada. Finalmente, se reflexiona sobre los aportes de dichas investigaciones y la relevancia de la in-corporación de contenidos teóricos y prácticos vinculados con la educación para la paz en la formación escolar de niñas, niños y jóvenes.
Derechos humanos y sistema penitenciario: poder, exclusión y contrapoder
Authors:   Universidad Nacional Abierta y a Distancia (Colombia), Flórez Eusse Yuner Ismar
Published: January 2022

En el presente ejercicio se realiza una reflexión sobre los derechos humanos y el sistema penitenciario, abordando categorías de análisis tales como poder, exclu-sión y contrapoder. Se pretende mostrar la vulneración de los derechos humanos en contextos de exclusión, donde el poder clasifica lo normal y lo que no lo es, poniendo en marcha distintos dispositivos de poder para “normalizar”; siendo en este proceso donde se limitan las libertades y se restringen los derechos, dejando de lado la dignidad humana. Se emplea una metodología hermenéutica, basada en una revisión bibliográfica que toma como principal autor a Michel Foucault, aunque puesto a dialogar con otros autores que permiten fortalecer y entender las categorías de análisis mencionadas, como es el caso del contrapoder, que es abordado desde algunos autores latinoamericanos que abogan por el em-poderamiento, la identidad y la liberación, no sólo de los pueblos, sino de los sujetos oprimidos.
The Effects of Firm Relational Capital on Export Performance: The Moderating Role of Technological Turbulence
Authors: Chowdhury Misbah Uddin
Published: January 2022

Global value chains (GVCs) offer a range of opportunities to manufacturers interested in increasing their export market share by utilizing their business relationships with other firms. In recent studies, it is recognized that relational capital helps manufacturing firms to enhance their competitiveness in global markets. However, prior research does not provide a conclusive account of the impact of relational capital on their export performance in general, and particularly in the context of developing countries. Drawing on a learning-based perspective and contingency approach, this study fills these gaps by theorizing the link between relational capital and firm performance with a focus on developing-country firms that participate in GVCs. Specifically, we propose that the relational capital of these firms will have a stronger positive impact on their export performance when the market and technological turbulence are lower. The results confirm the key hypotheses by showing that developing-country firms' relational capital with buyers has a positive and significant impact on their export performance and that technological turbulence negatively moderates the relationship between relational capital with buyers and export performance. Overall, this research extends the literature on knowledge transfer, interfirm relational capital, and business performance in a developing country context.
Pandemi Covid-19: Inflasi dan Pengangguran Dalam Perspektif Ekonomi Islam
Authors: Hasanah Mauizhotul
Published: January 2022

This study aims to analyze the tradeoff between inflation and unemployment based on an Islamic economic perspective. Inflation and unemployment are important indicators of economic performance and both are major problems that must be controlled immediately because they will have a wide impact on various things, especially during the Covid-19 pandemic conditions. Inflation and unemployment have a negative relationship, the lower the level of unemployment, the higher the inflation rate. One of the causes of inflation is the increased price of goods which results in an increase in production costs. Whereas in Islam the existence of costs is caused by the monopoly of goods or labor, but in an Islamic-based market it is not applied. Therefore Muslim entrepreneurs will not face high costs to meet excess wages because workers get wages that must match the earned productivity. Furthermore, the handling of unemployment affected by the Covid-19 pandemic can be done by maximizing the Islamic economic philanthropic scheme, namely zakat, infaq, shadaqah, and lending on a qardhul hasan basis.
Rola leasingu w promowaniu samochodów elektrycznych
Authors: Grzywacz Jacek , Jagodzińska-Komar Ewa
Published: January 2022

Popularność leasingu w Polsce przekłada się na wzrost wszystkich segmentów tego rynku. Różna jest jednak dynamika poszczególnych segmentów i ich struktura. Szczególnie szybko rośnie udział segmentu pojazdów lekkich i właśnie rynek motoryzacyjny posiada tu największe znaczenie. Coraz ważniejszą rolę odgrywają projekty inwestycyjne związane z ochroną środowiska i dlatego firmy leasingowe oferują finansowanie firmom, zwłaszcza z sektora małych i średnich przedsiębiorstw w zakresie urządzeń i materiałów energooszczędnych. Projekty te mają pozytywny wpływ na polską gospodarkę i zwiększają konkurencyjność przedsiębiorstw, jak i zmniejszają dwutlenek węgla w naszym kraju. W opracowaniu sformułowano następującą hipotezę: że leasing ma istotny wpływ na wzrost użytkowania samochodów elektrycznych oraz jest najpopularniejszą formą korzystania z tych pojazdów. Po przeprowadzeniu analizy stwierdzono, że postawiona hipoteza została potwierdzona. Leasing zajmuje obecnie w Polsce niekwestionowaną, wysoką pozycję w finansowaniu działalności przedsiębiorstw.

Przyjętą metodą badawczą jest analiza tekstów, materiałów i danych z zakresu ekonomii i filozofii, a także przytoczonych fragmentów badań własnych przeprowadzonych w poszczególnych latach.
Wydatki publiczne na świadczenia rzeczowe opieki długoterminowej w Polsce – konwergencja czy dywergencja na poziomie województw
Authors: Wrotek Małgorzata
Published: January 2022

Różnice przestrzenne w zaawansowaniu procesów starzenia demograficznego ludności Polski, sugerują występowanie silnego regionalnego zróżnicowania popytu na usługi opieki długoterminowej, w tym na świadczenia rzeczowe (usługi pielęgnacyjno-opiekuńcze). Obserwowane obecnie zróżnicowanie demograficzne województw jak również konwergencja bądź dywergencja określonych czynników demograficznych istotnych z punktu widzenia potrzeb opiekuńczych powinny więc wpływać na oszacowania poziomu wydatków publicznych na opiekę długoterminową, w tym również na zmniejszanie bądź zwiększanie dyspersji regionalnej w tym zakresie. Celem artykułu jest identyfikacja kluczowych zmiennych kształtujących poziom wydatków publicznych na świadczenia rzeczowe opieki długoterminowej sektora ochrony zdrowia i pomocy społecznej oraz zbadanie występowania konwergencji bądź dywergencji tychże wydatków w ujęciu regionalnym. W badaniu wykorzystano trzy miary konwergencji: sigma, beta – absolutną i beta warunkową. Do weryfikacji statystycznej istotności wybranych zmiennych wykorzystano metodę regresji panelowej na danych rocznych dla województw.
COVID-19 preventive behaviours among population 50+ in Poland
Authors: Styrc Marta
Published: January 2022

In order to reduce the spread of the SARS-COVID pandemic a set of measures was recommended to reduce the spread of disease and protect individual health. In this article we analyse what factors are associated with utilisation of preventive measures: washing hands, using disinfectant and covering cough among the population of men and women aged 50+. Using Survey of Health, Ageing and Retirement data we estimate logistic regression models for the increased utilisation of each of the preventive behaviours on demographic, socio-economic and psychological characteristics. The results indicate that the likelihood of taking health precautions depends on age, education, level of conscientiousness, and staying isolated. For men it also matters whether they live with a partner. We discuss what the findings mean for managing preventive behaviours.
Internalizing Gendered Identities: Children’s Conversations about Cartoon Characters
Authors: Afzal Saman
Published: January 2022

In today’s digital world, children spend most of their time watching and enjoying cartoons on smart devices. We, therefore, argue that cartoons leave an impact on the identity of children. This research explores how children accumulate gender stereotypes using Bandura’s social learning theory (1977) and identification with media characters’ theory by Cohen (2001). The study investigates how children of 3rd to 5th grade construct identity under the influence of popular cartoon characters. Based on the child-centered methodology, including controlled conversation patterns with children from ten private schools of Islamabad, this study gives children a voice in exploring their gendered identities. Findings suggest that boys are inclined to save and rescue, show power, desire knighthood, and admire the stout and muscular body of male cartoon characters while girls are fascinated by submissiveness and politeness, beauty, and the ideal physique of female characters. The findings, further, suggest that boys follow the stereotypes; however, in certain instances, girls try to break the traditional stereotypes and express their desire to be independent and powerful. Hence, children in the form of these traits internalize gender stereotypes. This study is significant as it sheds light on how this popular medium inculcates gendered stereotypes in children’s minds shapes their personas and how much they value them.

Published: January 2022

Background: The purpose of the present study was to evaluate the efficacy of marsupilization of dentigerous cyst in children and adolescents as a line of treatment and its role in involved teeth preservation, during the last three years in maxillofacial department, King Fahd specialist hospital, Qassim, Saudia Arabia. Methods: twelve patients with dentigerous cysts were included in this study, 7 males and 5 females. Age range was 9 – 15 years old. Follow up to one-year postoperatively, early and late radiological evaluation. Followed by orthodontic alignment of teeth if needed. Results: Marsupialization (decompression) is a reliable technique for management of dentigerous cysts in children and adolescents for cyst healing and involved tooth preservation, but it needs long periods of follow up, cooperative patient and sometimes orthodontic work up. Conclusions: Marsupialization of dentigerous cyst should be considered in children and young adults, especially in large cysts and when tooth preservation is desirable.

The aim of this study was to describe the effect of the substitution of butter with avocado flesh on the organoleptic properties of the thousand layers roll. The second objective of this study was to describe the community's acceptance of the hedonic test on the substitution of butter with avocado flesh on a thousand layers roll. Based on the Duncan test, the entire treatment had significant differences in texture and taste. Whereas color and scent have differences in treatment F0 and F1 but have significant differences in treatment F2 and F3. This is because the texture and taste are largely determined by the level of maturity of the avocado, not all avocados can be precise and the weight ratio used between treatments. In addition, the fiber and fat in the avocado are stronger so that the more avocado content, the thicker it will be and dominate the rolled legit layer cake. In terms of quality of treatment F3 (60% butter, 40% avocado) has the highest value with color 5.68 (like category), texture (like category), scent 5.48 (somewhat like category) and taste 5.84 (like category). Of the four treatments, there was one treatment that was somewhat disliked by the panelists, namely F0 where the composition of 0% avocado butter with an inaccurate formula resulted in the finished product of rolled legit rolls, which differed greatly from the finished results of the other three treatments (F1, F2 and F3). This is because the avocado content cannot fully replace the function of butter in the thousand layers roll.

Published: January 2022

This study aims to identify the Gonggong (dog conch) supply chain in Bintan Island and identify its potential to become a culinary tourism destination besides the well-known natural and cultural tourist destinations in Bintan Island. This is motivated by the existence of gonggong as endemic animals that only exist in the Riau Islands, especially in Bintan and Bangka Belitung Islands so that gonggong is known as a typical food of Bintan Island. However, this typical of Bintan Island is not yet nationally known like special foods of other regions. This study was conducted in Bintan Island using a descriptive-qualitative method to describe the supply chain and the potential of gonggong as a special food for culinary destination. Data was collected through in-depth and structured interviews and observations. The results of this study indicate that in terms of quantity, gonggong is available throughout the year with a tendency of abundant availability, and as a result, it has the potential of culinary destination for Bintan Island. In order for the gonggong culinary to be attractive to tourists, it needs packaging in a series of tourist travel attractions emphasizing foods and integrating it with cultural values of the local communities and with the rich natural phenomena of Bintan Island. Digital marketing strategies can be used for the purpose above through various social media or e-commerce platforms that are packaged in an attractive manner to build tourists’ perception that Gonggong is the typical culinary destination of Bintan Island that is worthy of visit.

Atrial fibrillation (AF) is the most common arrhythmia attacking 1. 5–2.0% of general population worldwide. It has a significant impact on morbidity and mortality globally and its prevalence increases exponentially with age. Therapies like catheter ablation or conventional antiarrhythmic drugs have not provided effective solution to the recurrence for AF over the past decades. Over 100 genetic loci have been discovered to be associated with AF by Genome-wide association studies (GWAS) but none has led to a therapy. Recently potential involvement of epigenetics (DNA methylation, histone modification, and non-coding RNAs) in the initiation and maintenance of AF has partly emerged as proof-of-concept in the mechanism and management of AF. Here we reviewed the epigenetic features involved in AF pathophysiology and provided an update of their implications in AF therapy.

Assimilating the atmosphere with multifractal entities, nonlinear behaviors in the framework of scale relativity theory regarding its hydrodynamic functionality are established at various scale resolutions. From this perspective, revealing a “hidden” symmetry of the specific multifractal force with the SL(2,R) group leads to synchronization of atmospheric entities on the basis of operational procedures (differential and integral Riemann-type geometries, harmonic mappings from Euclidian to hyperbolic space, variational principles, and others) that imply cellular self-structuring, laminar channels and singularities as turbulence generators. These behaviors can then be assimilated and compared with recent discoveries regarding laminar channels found in atmospheric turbulence through lidar data processing.
Nyexon Rock Avalanches: A Special Intrusion Restraint Mechanism, Tibet, China

The Nyexon Rock Avalanches in the southern Qinghai-Tibet Plateau is a huge scale earthquake-induced slope disaster in the Holocene, the accumulation area has distinct sedimentological characteristics, which is of great significance for studying the intrusion and restraint mechanism during long-distance transportation of large rock avalanches or debris avalanche. This long-distance transportation induced a series of landform types, such as ridges, hills, and ravines; they are widely distributed in all areas and extensively developed shear zones, jigsaw cracks, and other structures within the sedimentary structure. With the analysis of DEM data and geological survey, two main types of basement structures and their transition relationships are distinguished; they play an essential role in the restraining bottom during rock avalanches. In the sedimentary structure, the block facies and mixing facies occupy the main body of the deposition from the center to the distal area. Under the basement restriction, mixing facies are formed between the bottom of the sedimentary layer and the basement sedimentary structure; the shear band is mainly developed along with the mixing facies and basement facies, which is accompanied by basement liquefaction and rheology. A sedimentary facies model is established based on the sedimentary structure sequence of the Nyexon Rock Avalanches transportation. After analyzing the failure mechanism of the rock avalanches, it is believed that in the initial stage of failure, the rock avalanches is transformed into a particle flow that is similar to the debris avalanche, which is restrained by the basement structure and lateral bound; then, an accumulated obstacle highland is formed in the central area after deceleration, making the transportation of the main fluid to deflect quickly.

This study aimed to investigate the impact of weight loss after laparoscopic sleeve gastrectomy (LSG) on cardiac structural and functional remodeling in obese Chinese. A total of 44 obese participants were enrolled consecutively. The physical, laboratory, electrocardiographic, and echocardiographic parameters of pre-and postoperative were recorded. The average follow-up time was 12.28 ± 5.80 months. The body mass index (BMI) of the patients with obesity was decreased from 41.6 ± 7.44 to 30.3 ± 5.73kg/m2 (P<0.001) after LSG. The systolic and diastolic blood pressure of the subjects was significantly reduced from 137.9 ± 15.7mmHg to 123.0 ± 16.0 and 83.4 ± 10.8 to 71.3 ± 11.7mmHg (P<0.001), respectively. The levels of fasting insulin and fasting blood glucose were significantly decreased (38.8 ± 32.1 to 8.43 ± 4.16 mU/L, P<0.001; 6.95 ± 2.59 to 4.64 ± 0.50mmol/L, P<0.001). Total cholesterol (TC, 4.66 ± 0.84 to 4.23 ± 0.75mmol/L, P<0.001) and triglyceride (TG, 1.92 ± 1.21 to 0.85 ± 0.30mmol/L, P<0.001) decreased significantly. Cardiovascular geometric parameters including aortic sinus diameter (ASD, 32.9 ± 2.83mm to 32.0 ± 3.10mm, P<0.05), left atrial diameter (LAD, 38.8 ± 4.03 to 36.2 ± 4.12mm, P<0.001), and interventricular septum thickness(IVS, 10.2 ± 0.93 to 9.64 ± 0.89mm, P<0.001) were significantly reduced. The ratio of weight loss (RWL) was positively correlated with the changes of LAD. The change of IVS was negatively correlated with the change of fasting blood glucose (GLU). Weight loss after LSG could effectively improve cardiac structural, but not functional, abnormality in obese Chinese.
