Authors: Chauniyal Devi Datt
Published: June 2022

Abstract

       Formation of river terraces, transverse faults along with the major thrusts, deformation of quaternary sediment, and mass movement results from the combined effect of the tectonic and climatic process, tectonic landforms developed across defining the boundary of North Almora Thrust (NAT) have imprints of late Holocene tectonic activities. The reactivation of thrust and faults has greatly influenced the topography of the Himalayan region. Considering this a series of geomorphic evidence of the Quaternary period has been reported along the strike-slip transverse fault near NAT at Kirtinagar in Lower Alaknanda valley of the Lesser Himalaya. Present tectonic landforms of the transverse fault indicated by various cutting of host rock, V-shaped valley, epigenetic gorge, unpaired river terrace, deflecting river course, offset drainage pattern, triangular facet, incision with higher uplift along with tectonic upheaval, and immature topography. The neo-tectonic sites were identified along with the road cut section and Kirtinagar terrace scarp. The tectonic structures and nature of sediments were analyzed and photographed during the field study. The minor structural features of Quaternary sediments are folding, faulting, thrusting, warping, and tilting. The samples of optical chronology were collected from discrete sand horizons. The OSL date was obtained using the single aliquot regeneration. The Optical Chronology of terraces sediments shows that the T2 and T3 levels of terraces are deposited around 4.6 Ka in the Holocene periods. Based on existing data it is assumed that the Lesser Himalayan thrust and faults were tectonically active during the early Holocene period. After that, the role of tectonic decreases and incision increases due to the climatic variability. The conclusive results of the study indicate that the neo-tectonic movements along NAT were more active in recent past times. It is concluded that the transverse strike-slip fault along NAT in the study section has been reactivated from time to time

The stratigraphy of the lower reaches and floodplains store mineral sediments, organic matter, pollen, and charcoal which are important proxies for understanding the environmental evolution that directly interacts with human activity.

The present study is based on four sediment cores (7 to 19 m long) from the Lower Danube floodplain in NW Dobrudgea, close to Galați-Măcin area. The cores were carefully described and sampled for grain size, loess on ignition, magnetic susceptibility, charcoal, pollen and radiocarbon dating to reconstruct the paleoenvironmental changes in a key region for Neolithic cultures dispersal across SE Europe. The results of these combined analyses from the four cores with a special focus on Jijila mastercore (placed in a lake derived from a former embayment) bring new data about the mid and late Holocene floodplain environmental changes and a new perspective regarding the first settlements emplacement in the study area. Lower Danube floodplain inhabitation is still a hotly debated subject. The archaeological findings suggest the first settlements date from the Bronze Age (La Grădini – Jijila; Brăila), whereas recent human bones datings point to an earlier inhabitation during the Mesolithic-Neolithic period (Brăiliţa). The newly obtained charcoal and pollen profiles on Jijila core show two intervals of higher intensity human activity, the first during the Neolithic period and the second during the mid and late Bronze Age. Both periods are highlighted with peaks in charcoal particles and pollen grains (cereals) indicative of human activity.

Marguerite Bay is located in the South-central part of the Antarctic Peninsula. The archipelago of the bay is rich in terms of coastal geomorphological features such as raised beach ridges as geomorphic markers of relative sea-level change. In this study, we focussed on Horseshoe Island and Calmette Bay where raised beach ridge levels were already identified. We employed a topographical survey to define the elevation and cosmogenic 10Be surface exposure dating method to define the age of major paleo shoreline levels. In the Gaul Cove located eastern coast of the Horsehoe Island we identified three major topographical levels and in the Calmette Bay four major topographical levels that raised beach ridges cluster. Paleoshoreline levels at 1, 7, 12, and 16 m asl yield 0.3 ka, 1.59, 3.31, and 3.33 kyr BP, respectively, in the Gaul Cove when we remove 2.9 ka inheritance that we obtained from the modern shoreline samples. However, shoreline levels are higher and ages are older on the Calmette Bay coast. Major levels are at 5, 8, 17, 27 and 35 m asl, and their cosmogenic 10Be ages yield 3.46, 3.19, 5.3, 5.9, and 7.2 kyr BP, respectively, in the Calmette Bay when we remove 1.94 ka inheritance that we obtained from the modern shoreline samples. Since the present sea level was eustatically stabilized at approximately 7 kyr BP we estimated uplift rates according to modern sea level. The uplift rate in the Horseshoe Island yields 5.53±0.88 mm/yr in the last 3.3 kyr, and in the Calmette Bay, it yields 4.52±0.40 mm/yr in the last 7.2 kyr.This study was carried under the auspices of Turkish Republic Presidency, supported by the Ministry of Science, Industry, and Technology, and coordinated by Istanbul Technical University (ITU) Polar Research Center (PolReC) and Turkish Academy of Science.

The watershed is a depression on the land’s surface, which is surrounded by higher land and drained by a river and its various tributaries. The streams are the morphologic elements of a basin that help draining the runoff reaching the Earth’s surface as rainfall, into a main water course. The present research had the objective of studying the hydrologic structuring of Paraopeba River Watershed located in the state of Minas Gerais, Brazil. The watershed was divided in 66 subbasins and geomorphological characteristics were calculated, namely those relevant for the assessment of hydrology and sediment transport. The materials and methods involved a geographic information system coupled with aerial photography interpretation methods that allowed a detailed geomorphologic analysis, irrespective of the large area of Paraopeba basin. The longitudinal profiles of water courses enabled to understand the three-dimensional development of stream networks while stream directions were linked to water-resources management. The results also exposed a relationship between landscape change and dynamic interactions between the physical and material environments triggered by natural and cultural forces. The actual shape of Paraopeba River watershed depends on the flowing streams and was strongly influenced by geologic heterogeneity. The singular features and processes that created a subbasin could be related with specific physical and environmental settings, that differed from place to place, whereas different landscape types were recognized as well as different landscape regions.
Future global debris flow susceptibility considering climate change, wildfire probability, and glacier retreat
Authors: Kurilla Laurie , Fubelli Giandomenico
Published: June 2022

It is widely accepted that climate changes will affect slope instability, and the presence and  prevalence of landslides are expected to be exacerbated.   Many areas of the world are experiencing increases in minimum, mean, and maximum temperatures and more frequent heavy precipitation.  Due to both climate change and projected population and urban growth, it is reasonable to assume the impact of debris flow  hazards will increase.  

With climate change and increasing temperatures, the likelihood of increased forest fires leads to an increased likelihood in post-fire debris flow frequency in those burn areas where other debris flow predisposing factors exist and rainfall amounts required to induce debris flows decrease. 

Future debris flow susceptibility models (RCP 2.6 and RCP 8.5) were developed and augmented with future wildfire probability, and areas of potential glacier retreat, both of which can subsequently act as amplifiers to global debris flow susceptibility.  The resulting debris flow susceptible areas are projected against future population and urbanization centers for a spatial view on human vulnerability.

 
Geotechnical characterization and slope stability evaluation of the gypsum quarry of Sogerela, Óbidos, Portugal

Published: June 2022

A geotechnical characterization of the gypsum quarry of Sogerela and its slope stability assessment, were carried out. The quarry is located at Avarela, in the municipality of Óbidos (western Portugal). For the evaluation of rock mass quality, the characteristics of the discontinuities were defined, which correspond to an important factor in the stability and behavior of the fractured gypsum rock mass affected by diapiric deformations. Laboratory characterization tests were performed, determining several parameters such as: apparent density, open porosity, slake durability index, Schmidt hammer rebound hardness, point load strength index and mineral identification with X-Ray Diffraction (XRD). Results obtained from field survey and the laboratory tests allowed to define the values of the geotechnical parameters and to perform the characterization and classification of the rock mass, using the Rock Mass Rating (RMR) and Geotechnical Strength Index (GSI).

The data obtained was used in the geomechanical simulation for slope stability analysis using SLIDE2 V9.0 and RocFall V8.0 software programs. The quarry slope stability was assessed with the definition of the possibility of slope failure considering the raise of the water table and in the eventual occurrence of an earthquake. The results allowed to verify that that the actual conditions seem to be stable, concerning global failure of the excavation slopes, despite the frequent fall of gypsum fragments adjacent to the quarry walls during and after rainy periods.

Geoparks are territories characterising by remarkale geodiversity and/or impressive geosites which deserves their preservation as well as the dissemination. This study deals with the description of the ecogeomorphology and past and current human use from remarkable geosites included in the Andalusian Geoconservation Inventory.  All of them are located in the Subbéticas Natural Park and Geopark area (Province of Córdoba, in southern Spain). This geopark belongs to the European and World Geopark Network since 2006. The landscape and geology of the Geopark are closely related; ridges are formed of hard limestone; valleys are created in areas underlain by softer argillaceous carbonates and other detrital sediments. The rocks, which range in age from the Jurassic to the Tertiary, were deposited approximately between 200 million years and 25 million years ago. The rocks are rich in fossils and are noted for their Mesozoic ammonites. The Geopark is internationally recognised as one of the most significant areas for the study of the evolution of this group of fossils. In total, there 16-geosites within the geopark besides four more in the surroundings. The geosites are mainly related to karstic processes and landforms, but also there are others related to geological structures and fossils. This study is focussed in sharing the results of their description from a holistic point of view considering ecogeomorphology and human uses in order to enrich the current information from all of them and improving their dissemination among the geopark visitors.

Published: June 2022

Current scientific knowledge of the deglacial history of Greenland is still spatially and temporally disperse, with a lack of data from several regions and time periods, as is the case for NE Greenland. A better understanding of the sensitivity of polar ice sheets to rapidly changing past climates is of key importance in the current climate scenario, where recent warming has affected the stability of ice sheets and thus accelerated global sea level rise. Here, we present new evidence of the glacial history of the 90-km long Young Sound-Tyrolerfjord system (NE Greenland) based on 78 10Be Cosmic-Ray Exposure (CRE) ages obtained from moraine boulders, polished surfaces and erratic boulders distributed across three tributary valleys (Zackenberg, Dolomit, Olsen) and at the head of the fjord (Tyrolerdal). The major deglaciation of the fjord occurred during Termination-1 (19-11 ka). At 13-14 ka, a period of major glacial shrinking was recorded, exposing also the highest surfaces of the region. No clear signal is detected in the area during the cold Younger Dryas phase. During the Early Holocene, glacial retreat accelerated, the lateral tributary glaciers receded and disconnected from the main glacier until the deglaciation of the fjord was completed by 10-11 ka. Since then, postglacial environmental (paraglacial, periglacial, slope, alluvial) dynamics have only slightly reshaped the landscape as Middle-Late Holocene climatic oscillations have not favoured large advances or retreats of the glacier fronts.
Evaluation of the return time of flash floods generated in the Roya Valley (Alpes Maritime, France) on October 2, 2020: What challenges does this type of event pose for risk management?
Authors: Fouache Eric , Desruelles Stéphane , Gorini Christian , Bianchi Nicoletta , Marchiel Adrien
Published: June 2022

The passage of the storm Alex favored on October 2, 2020 the triggering of very intense rainfall in the coastal valleys of the Alpes-Maritimes, including that of the Roya, which caused many devastating hydro-geomorphological processes, mainly floods and landslides. The destruction, which has affected modern and ancient infrastructures, has been considerable, with dramatic social and economic consequences. The processes have also unearthed archaeological remains dating from the Bronze Age to the modern era.

Meteorological analyses confirm the exceptional character of this Mediterranean episode, while marine sedimentary records made in the deltas of the Var crossed with C14 dating of ancient torrential deposits identified in the Roya watershed indicate a return time of about half a millennium.

The major difficulty in the case of the Roya is that the reactivation of the entire late glacial active band has upset the geometry of the river's major bed compared to what it was before Storm Alex. In the areas of torrential deposits, there is a widening of the bed of the order of 1 to 10 and a rise of several meters in the height of the alluvial table. This major modification implies that before defining the new risk zones and deciding on the reconstruction of the infrastructures, the impact of the floods recorded in the past should be modeled according to this new geometry of the bed. Moreover, in the context of global warming, it is not excluded that we observe a higher recurrence of events such as storm Alex. We present the preliminary results of our research program (STORY: "Risks and societies in the Roya basin: multidisciplinary and multi-temporal analysis, from the slopes to the sea") and discuss the difficulties in reconciling the perceptions of the different actors, the necessary time of research not always easy to articulate with the urgency of reconstruction and the vital need to open up sectors that otherwise risk being permanently abandoned by the populations.

Sedimentary mass balance modelling of the Jezero crater fluvio-deltaic system
Authors: Silva David C. A. , Vaz David A. , Di Achille Gaetano , Le Deit Laetitia
Published: June 2022

Martian deltaic deposits are good indicators of water distribution and provide insight into the climate evolution of Mars [1]. A notable case is the fan deposit located in Jezero crater, currently being studied by the Perseverance rover. Hydrated silica-bearing deposits were identified in this area [2, 3, 4], and the overall stratigraphy and morphology point to an evolution passing through a progradation and a transgression phase, to an erosion episode [5]. All these evidences suggest that this deposit was formed by fluvio-deltaic activity in an ancient lake basin [6] during the late Noachian or early Hesperian epochs [7]. After its formation, the deposit likely suffered a complex and profound exhumation [8] which we will try to constrain through a mass balance analysis.

Here, we present the first results of a project seeking to understand the depositional and post-depositional evolution of the Jezero delta, including the study of its hydrographic basin [9]. We will focus on a mass-balance survey, analyzing and comparing the volume of sediments that were eroded from the basin and deposited into the crater. We integrate HRSC, CTX and HiRISE data to create a regional DTM and orthophoto map covering the Jezero crater and its drainage basin. These datasets enable us to estimate the volume of sediments eroded from the drainage basin, as well as the present-day volume of the fan deposit. Finally, we will apply the mass balance model introduced by [10], aiming at evaluating putative sediment offshore loss and post-depositional fan erosion. This will allow to infer the initial volume of the deltaic deposit and test different lake water levels.

Geomorphological adjustments in a partial avulsion: the Peixe River, Brazil
Authors: Morais Eduardo , Montanher Otávio Cristiano
Published: June 2022

The avulsions cause intense transformations in the fluvial landscape of meandering rivers. However, the morphometric and sedimentological adjustments during this process are still poorly understood. The Peixe River, located in the southeastern region of Brazil, has a partial avulsion, established with an avulsion channel of 14 km long, which remains for more than 48 years. In this study, we investigated variations in the sinuosity and width channels with remote sensing, as well as sedimentological features in channel banks of the parental channel with sampling in fieldwork. The sinuosity analyses showed between the years 1985 and 2020 a subtle increase in the avulsion channel (1.11-1.15), followed by a decrease in the parental channel (2.00-1.67). The decrease and increase in the mean width in, respectively, the parental channel (40.7-33.6m ±0.5m) and the avulsion channel (26.4-31.1m ±0.5m) between the years 2011 and 2020 resulted in a recent and approximated equivalence of width between the channels. The bank channel deposits in a segment, which includes the parental channel, were discriminated in the top and bottom layers. The top layer, which has coarser sediments and a lower concentration of organic matter than the bottom layer, showed a significant increase in muddy sediments and organic matter in the avulsion reach (t-test, homogeneous variance, p-value = 0.0013 and 0.048, respectively). Therefore, morphometric and sedimentological parameters evidence recent reorganizations of the drainage network and in the depositional model of the floodplain due to the development of partial avulsion.
Holocene Evolution and Distribution of Large Structural Estuaries
Authors: Baum Mitchell , Kennedy David , McSweeney Sarah
Published: June 2022

Sediment deposition with coastal systems is determined by the interaction between hydrodynamic processes and morphology. For Barrier Estuaries, the development of a confining sediment barrier at the mouth developed after the Holocene Marine Transgression (HMT) introduced wave processes to a coastline. However in some estuaries, such as San Francisco Bay, the morphological features which restrict the mouth developed before the HMT and are comprised of resistant bedrock, which responds relatively slowly to changes in hydrodynamic conditions. These types of structurally defined estuaries have been identified regionally. Recently a global review of the distribution and abundance of Large Structural Estuaries (LSEs) has been conducted, and LSEs were identified across the worlds coastlines. Several of the LSEs identified appear to have reached an equilibrium, where sediment is no longer being deposited, and they remain dominated by intertidal mud flats. Unfortunately, the sediment deposition within these systems during the Holocene not well understood. In this presentation I will review the key findings of the global review, interpret patterns of Holocene infill in a South East Australian LSE, and discuss the possible influences of the Holocene evolution of LSEs on their distribution and abundance.
Application of a Geobiodiversity Index to Natural Protected Areas in Northern Portugal

Published: June 2022

The majority of studies on geodiversity and geoheritage have been focused exclusively on the analysis and evaluation of abiotic elements. Although some authors have highlighted the important connections between abiotic and biotic elements, it was not enough to highlight them systematically. In this sense, it is necessary to do the geodiversity potential analysis in a more complete sense. That is, all elements should be contemplated.

In the context of the project “Clictour - Climate change resilient tourism in protected areas of Northern Portugal”, three protected areas were chosen as case studies. These areas are located in northwest Portugal, namely the Peneda-Gerês National Park, the Alvão Natural Park, and the Litoral Norte Natural Park. Despite their geodiversity richness, these parks were established mainly based on their biodiversity.

The objective of this proposal is the application of a geobiodiversity index. This index is based on the work done by Steinke (2021), which is capable of indicating the most relevant areas of geological, geomorphological, and vegetational aspects to be conserved within existing legal instruments.

The methodological procedures were centered on segmenting the three areas in hexagonal cells. The parks were subjected to a spatial matrix analysis in GIS and geostatistical environments capable of articulating the various elements and generating an agglutinating index for each cell.

The results reveal the existence of a high index value for geodiversity in the different protected areas, being more significant and extensive in the Peneda-Gerês National Park. It also shows the importance of integrating the analysis of geodiversity and biodiversity, especially in natural protected areas. The present study points out the importance of the compartmentalization approach in hexagonal cells, capable of providing a multilevel approach in studies of complex spatial analysis.

This study was developed within the scope of the CLICTOUR project (Project NORTE-01-0145-FEDER-000079), supported by the European Regional Development Fund.
Morphometry, distribution, and evolution of sinkholes on the western shore of the Dead Sea
Authors: Sevil Jorge , Gutiérrez Francisco
Published: June 2022

Sinkhole development causes significant economic losses in many karst regions worldwide. Very often, the subsidence damage is related to sinkholes induced by various types of human activity that involve alterations in the surface and/or underground hydrological systems. One of the most striking examples of human-induced sinkhole hazard is found in the rapidly evolving eogenetic salt karst of the Dead Sea. Here, the decline of the lake level caused by the use of the water in the catchment (diversion from the Jordan River) and the lake basin (pumping to evaporation ponds) has resulted in the lakeward displacement of the brackish water - fresh water interface and the development of thousands of sinkholes since 1980s. The sagging and collapse sinkholes developed in the mud flats and gravelly alluvial fans at the lake margins tend to form tightly packed alignment and clusters. These can evolve by various processes (new sinkhole occurrence, lateral growth by mass wasting, coalescence) into expanding compound subsidence depressions as much as thousands of square meters in area. Sinkhole damage in the area includes the destruction of human structures (e.g., roads, touristic facilities, dikes in the evaporation ponds) and accidents involving the shallowing of people. The extremely high activity of the sinkhole areas not only pose a major threat, but also offers and exceptional opportunity to study quantitatively their spatial and temporal evolution. The results of the analyses have implications for hazard assessment (e.g., distribution of new sinkholes, probability of occurrence, frequency-size relationships). This work analyses the geomorphological evolution between 2005 and 2021 of an area on the western shore of the Dead Sea south of the Nahal Darga alluvial fan, including several sinkhole clusters and hundreds of new sinkholes. Time-lapse cartographic inventories have been produced using aerial and satellite imagery from multiple dates, high-resolution photogrammetric models produced using aerial photographs taken from drones, and field surveys. The quantitative analysis of the sinkholes (e.g., morphometry) and their evolution patterns have been carried out coupling GIS and R software environments.
Temporal evolution of crack propagation characteristics in a weak snowpack layer: conditions of crack arrest and sustained propagation

Published: June 2022

Abstract. For a slab avalanche to release, the system, consisting of a weak layer below a cohesive slab, must facilitate crack propagation over large distances – a process we call dynamic crack propagation. Field measurements on crack propagation at this scale are very scarce. We therefore performed a series of propagation saw test experiments, up to ten meters long, over a period of 10 weeks and analyzed these using digital image correlation techniques. We derived the elastic modulus of the slab (0.5 to 50 MPa), the elastic modulus of the weak layer (50 kPa to 1 MPa) and the specific fracture energy of the weak layer (0.1 to 1.5 J m-2) with a homogeneous and a layered slab model. During crack propagation, we measured crack speed, touchdown distance and the energy dissipation due to compaction and dynamic fracture (5 mJ m-2 to 0.43 J m-2). Crack speeds were highest for PSTs resulting in full propagation and crack arrest lengths were always shorter than touchdown lengths. Based on these findings, an index for self-sustained crack propagation is proposed. Our data set provides unique insight and valuable data to validate models.

The Effects of Standardised versus Individualised Aerobic Exercise Prescription on Fitness-Fatness Index in Sedentary Adults: A Randomised Controlled Trial
Authors: Kirton Michael J. , Burnley Mitchel T. , Ramos Joyce S. , Weatherwax Ryan , Dalleck Lance C.
Published: June 2022

A poor Fitness Fatness Index (FFI) is associated with type 2 diabetes incidence, other chronic conditions (Alzheimer’s, cancer, and cardiovascular disease) and all-cause mortality. Recent investigations have proposed that an individualised exercise prescription based on ventilatory thresholds is more effective than a standardised prescription in improving cardiorespiratory fitness (CRF), a key mediator of FFI. Thus, the aim of the current study was to determine the effectiveness of individualised versus standardised exercise prescription on FFI in sedentary adults. Thirty-eight sedentary individuals were randomised to 12-weeks of: (1) individualised exercise training using ventilatory thresholds (n = 19) or (2) standardised exercise training using a percentage of heart rate reserve (n = 19). A convenience sample was also recruited as a control group (n=8). Participants completed CRF exercise training three days per week, for 12-weeks on a motorised treadmill. FFI was calculated as CRF in metabolic equivalents (METs), divided by fatness determined by waist to height ratio (WtHR). A graded exercise test was used to measure CRF, and anthropometric measures (height and waist circumference) were assessed to ascertain WtHR. There was a difference in FFI change between study groups, whilst controlling for baseline FFI, F (2, 42) = 19.382 p < .001, partial η2 = 0.480. The magnitude of FFI increase from baseline was significantly higher in the individualised (+15%) compared to the standardised (+10%) (p = 0.028) and control group (+4%) (p = <.001). The main finding of the present study is that individualised exercise prescription had the greatest effect on improving FFI in sedentary adults compared to a standardised prescription. Therefore, an individualised based exercise prescription should be considered a viable and practical method of improving FFI in sedentary adults.

The issue of collective memory refers to the practices of societies to forget and remember together. Our memory has a temporal as well as spatial implication. Because space is an indispensable element in building social memory and acts as the main actor in our experience and meaning of time. In this context, the importance of memory spaces increases in societies whose history has gone through war or genocide and whose memory has been eroded by speed and technology. On the other hand, social memory exists with certain means and tends to be erased by these means. Mass media is one of the most important tools in building social memory. As a matter of fact, mass media have the potential to be determinative in what they want to be reminded, as they can cause a social amnesia by choosing what they want to be forgotten. Television is one of the oldest and most widely used mass media. Cartoons, on the other hand, have become an important element of my mass communication with the inclusion of channels that only broadcast cartoons in the broadcasting life. On the other hand, cartoons serve as an agent in the transfer of social memory to new generations. Rafadan Tayfa, which is broadcast on TRT Children's channel, is a cartoon series that is watched by children and is popular with families because it is suitable for traditional codes.

يهدف هذا البحث إلى دراسة لامية الشنفرى وتحليلها من حيث الرؤيا الفكرية التي طرحتها والملامح الأسلوبية التي تميزت بها، فقد عكستْ القصيدة من حيث الموضوع والبناء الفني رؤية خاصة بها، وخصوصية فنية ميزتها عن غيرها من أشعار الصعاليك. إن لامية الشنفرى تشكل لوحة متكاملة لحياة الصعاليك بكل خشونتها وصعوبتها، وما يكابده الصعاليك يوميًا من صعوبة العيش، ومقاومة الجوع، ومحاربتهم للطبيعة بكل قسوتها وصعوبتها، ممّا جعلهم في صراع دائم مع تلك الظروف للبقاء على قيد الحياة التي ألجأتهم إليها ظروف الحياة والتقاليد البدوية، فهي صورة صادقة لما عرف عن شعرهم وعن أخبارهم، واستطاع الشاعر من خلال رسمه الدقيق لهذه الحياة العصيبة عبر صياغة جميلة توشحت بقالب قصصي فني مميز الكشف عن رؤيته تجاه المجتمع والحياة، والذات، والتركيز على القيم الغائبة في مجتمعه سعياً إلى بناء المجتمع المتكافل. لو كانت الحياة شجرة لكان الجمال زهرها والشعر طائرها، رغم أن الزمن باعد بيننا وبين ازدهار هذه القصيدة فمازال لم يفقد سلطانها الوجدانية على أنفسنا، ولم يفقد سطوتها على أحاسيسنا، كلما قرأناها قراءة متأنية فنجد منها متعة وجدانية، ودوافع الحماسة، وتدفق الحيوية، فهي تجسد لنا كيف يسمو المرؤ بوجدانه وإحساسه وذوقه، وتعرض لنا كيف يكون الأدب الحقيقي في لفظه وفي معناه، في خياله وفي تعبيره، في عمقه وفي دقة حسه، فتصقل نفوسنا وتحركها وتزيدها نورا ونارا.

Em março de 2020 foi necessário começar a repensar a presencialidade das atividades acadêmicas no Brasil, em virtude das limitações impostas pela COVID-19. A Faculdade de Odontologia da Universidade Federal de Pelotas (FO-UFPel) possui diversos projetos de extensão, entre eles o Endo Z, o qual cumpre importante papel social desde 2014, por meio da realização de tratamentos endodônticos e do fornecimento de treinamento especializado para discentes e profissionais. Desde junho de 2020, esse projeto iniciou seus Seminários em Endodontia, os quais ocorrem remotamente via e-plataformas como: Google Meet, Zoom e YouTube. Esses seminários possuem a finalidade de continuar a cumprir o papel social do projeto e de levar uma educação continuada à comunidade por meio da extensão universitária. Diante disso, o objetivo deste estudo foi avaliar a satisfação dos ouvintes das atividades remotas do projeto por meio da aplicação de um questionário on-line. A pesquisa teve uma adesão de 39,4% dos ouvintes, ou seja, das 160 pessoas que tiveram acesso ao questionário, apenas 63 responderam. Logo, foi traçado um breve perfil dos ouvintes, classificou-se de forma quantitativa e qualitativa a satisfação deles e coletou-se depoimentos e sugestões acerca da metodologia remota do projeto de extensão Endo Z. Portanto, é evidente que os participantes dos Seminários em Endodontia mostraram-se satisfeitos, pois o aproveitamento e o retorno dos alunos foram extremamente positivos, incluindo relatos de gratidão pela oportunidade de acesso às aulas sobre Endodontia em meio a este período de pandemia da COVID-19.
Prehyperuricemia: New Milestone in Metabolic Disorders
Authors: Subbu Dr. GR , N. Dr. Anita , Hari Dr. K
Published: June 2022

The global population is living amid a metabolic explosion. The prevalence of hyperuricemia, as a metabolic disorder and a causal agent of non-communicable diseases, has been gearing up rapidly worldwide during the last two decades due to consuming a high purine diet, alcohol, red meat, high fructose-containing food, and lifestyle changes. The invisible bond between hyperuricemia and many non-communicable diseases is more robust than before. During the evolution of hyperuricemia, systemic inflammation develops, leading to endothelial dysfunction and end-organ injury. These molecular changes were not recognized previously. Hyperuricemia is now a metabolic, more clearly a vascular disorder than a crystallization disease. Asymptomatic hyperuricemia is no more benign, and gout is not synonym with hyperuricemia or vice versa. Diagnose hyperuricemia in an early stage at a high normal level and control it to prevent the development and complications of many hyperuricemia-related extra-articular diseases. For more acceptance and importance, this high normal level of serum uric acid can be named prehyperuricemia. As in the case of prediabetes and prehypertension, prehyperuricemia should be diagnosed early irrespective of age and sex; preventive measures have to be taken and maintain uric acid at a safer level.
