Geomorphology of the continental shelf west of Ireland
Authors: McCarron Stephen , Praeg Daniel , Monteys Xavier , Craven Kieran , Thébaudeau Benjamin
Published: June 2022

The continental shelf region West of Ireland contains a rich geomorphic and sedimentary record of glacially-influenced marine processes, including ice sheet extension from Ireland into the Atlantic during the last cold period (Late Midlandian glaciation in Ireland).  Intricate sets of curvilinear ridges of varying form and scale across the outer shelf have been recently associated with grounded glacial ice withdrawal from maximum limits.  The region lies at the southern limit of the glaciation of the Atlantic margin of northwest Europe, and thus occupies an important position in palaeoglaciological reconstructions.  Studies of seabed morphology west of Ireland have been greatly enhanced by exhaustive multibeam bathymetric coverage of the Irish National Seabed Survey, associated sediment sampling and high-resolution shallow seismic profiles; in places, these have been complemented by the use of industry 3D seismic data cubes to visualise the internal structure and geomorphology of glacigenic ridges and large-scale sediment aprons. This paper presents observations from combined sediment ground truthing, high-resolution geophysical and bathymetric data, focusing on the Porcupine Bank, Saddle and Inner shelf areas of the Western Irish Shelf, in order to examine available models of shelf glaciation.

Published: June 2022

This study confronts local environmental proxies (i.e., pollen, charcoal, paleofauna) with ancient sources documenting Kilia/Lycostomo Byzantine-Genoese settlement at the mouth of the northern Danube's distributary to reconstruct environmental changes which render difficult the localization of the Middle Age settlement. Historical data seem contradictory, while systematic archaeological research has been extremely difficult on the Chilia branch, the modern border between Romania and Ukraine. Yet, after the complete reevaluation of all the sources in relationship with their reconstructed paleoenvironments, we propose to locate the major Byzantine and Early Modern trading centre Lykostomion/Licostomo as well as Chilia at Kilija/New Chilia (now in Ukraine), on the Bugeac plateau, on the left bank of the Danube’s northern branch (itself called Chilia, former Lykostoma). Old Chilia (now in Romania), whose name was always taken as proof of the location of the famous historical city of Chilia, lacks archaeological traces of urban occupation before the 19th-20th century. In fact, this loess island in the delta, on the southern shore of the Chilia branch, has been used only for subsistence activities (fisheries, agriculture, husbandry) and for supporting the storage capacities of the main harbour of Lykostomion/Licostomo-Chilia, situated under the modern harbour of New Chilia. Besides texts and some scarce archaeological reports, this localisation is now supported by two sedimentary cores (PAR 1 and KIL 1) which allow the reconstruction of the Chilia branch progradation, with an absolute chronology based on 14C dates. Vegetation, charcoal and microfauna occurrence in the KIL 1 sediments of the last ca. 700 yrs are excellent proxies for the high-resolution study of the local deltaic dynamics under natural and human pressure. For the first time, they reveal information about the maritime and riverine milieux developing at the place where this trading hub was founded, the living conditions (food, housing, heating) of its inhabitants and the ecological changes related to their demographic fluctuations. Most interestingly, they show the environmental impact of the military conflicts and urban re-foundations, which occurred in the 13th, 15th and 18th centuries at this major gate of SE Europe.

Published: June 2022

Lara is located in the northern litho-structural domain of the Central African Fold Belt that includes plutonic landforms. The latter constitutes a natural wealth that has been studied in order to increase the geotouristic offer in the Far North Region of Cameroon. Several field and laboratory works have been carried in the study area and in the University of Maroua respectively. Indeed, the inventory, the selection and the study of plutonic landforms with particular shape, representativeness and geological features have been made. The locality of Lara is made up of plutons that are composed of fine to coarse granites encompassing white and pink micas, quartz and feldspar. Several granitic geomorphosites are found in Lara: (1) primary geomorphosites include inselbergs and flagstones. Four inselbergs are found in the study plot with altitudes of 435, 675, 690 and 558 meters respectively. They are conical in shape and are made up of rocks field. Flagstones are mostly elliptical in shape and cover surfaces of up to ten square meters; (2) secondary geomorphosites are tors, pedestal rocks, boulders and shelters. Tors and pedestal rocks are vertical constructions with variable highs and shapes that embellish the inselbergs slopes and piedmonts. Boulders present mainly rough surfaces and exceptional shapes, ranging from dog, mushroom to a bell... Their accumulation built several shelters of significant cultural value; (3) tertiary geomorphosites are taffoni and enclaves. Taffoni are of various sizes found on some boulders and flagstones where some are coalescent. Enclaves are composed of coarse-grained pegmatites and xenocrysts quartz. In the Far North region of Cameroon touristic offer is only focused to National Reserves and cultural events although the diverse geoheritage components present in the region. Thus, the Lara’ plutonic geoheritage constitutes an asset for the enhancement of the touristic offer in that region.
Investigation on the Manengouba Volcano’s geomorphosites (Cameroon): case of holo-magmatic and hydro-holomagmatic cones

Published: June 2022

The Manengouba Volcano (MV) is one of the voluminous apparatus that composes the Cameroon Volcanic Line. It is located between Mounts Cameroon and Bambouto. It has been built between 1.55 Ma to Recent years through relevant progressive tectonic and volcanic phenomena. These events characterize the first sequence volcanism of the MV’s history. They were responsible of the building up of two fitted caldera volcanoes (Elengoum and Eboga) that compose MV. The second sequence volcanism occurred following the collapse of the Eboga caldera. It was animated by several explosive and fissural eruptions that established along the MV numerous adventive landforms. A study of the latter is of paramount importance in understanding of deposits that constitute the geomorphosites and the evolution of the geomorphology of MV. It appears from the field and laboratory investigations that the MV includes around 70 holomagmatic and hydro-holomagmatic cones. Holomagmatic cones have basal diameters between 400 and 1000 m, heights less than 100 m relative to the surrounding terrain, and external slopes greater than 50°. The majority of these cones have three main directions namely N20-N40, N60-N70 and N120-N130. These cones are composed of pyroclastic projections, in particular lapilli, bombs, blocks and scoria. These projections are of various sizes and form more or less thick layers, defining a more or less clear stratification from the base to the top, with or without granoclassing. These pyroclastites are often associated with cone bottom flows that are either compact and prismatic in structure, or compact at the base and overlain by 30-60 cm layers of scoriaceous lava. Pyroclastites are the last lava flows and are at the origin of the partial or total breaking of several cones in the MV. The hydro-holomagmatic cones are the result of phreatomagmatic explosion processes and include the Manengouba Twin Lakes (Male and Female) and a Bassin (Djeu-Seh). Their heights vary from 10 to 30 m above the surrounding terrain. The external slopes are weak (10 to 15°) contrary to the internal slopes which are abrupt (more than 60°). These cones are of major orientation SW-NE and are also composed of pyroclastic projections but with fine and coarse ashes. These cones make MV one of the most complex volcanoes of the LVC. The high number of these cones reflects the high degree of fracturing of this volcano. The stratification of different deposits provides information on the rhythm of explosions that governed the history of each cone. These cones are geomorphosites whose scientific value makes them a natural laboratory for geoeducation and research.
ASSESSING THE USE OF SENTINEL-2 FOR EVALUATION OF ARCTIC COASTAL EROSION: Potential and Limitations (Beaufort Sea Coast, Canada)
Authors: Bilbao Sofia , Vieira Gonçalo , Bartsch Annett , Efimova Aleksandra
Published: June 2022

Permafrost is a crucial element in the cryosphere and an essential climate variable (ECV) of the Global Climate Observation System (GCOS). The Arctic represents 34% of the global coastlines (Lantuit, 2012). In the context of the RCP 8.5 scenario for 2040-2060, the IPCC projects for the Arctic an average increase of the annual air temperature of 7 ºC compared to 1880-1920 (Guyet al., 2021). Hence, the Arctic is one of the most vulnerable regions to climate change in the world. The Arctic is undergoing rapid transformations (Nielsen et al., 2020). This tendency will grow with the increasing frequency and magnitude of coastal erosion events, as processes are enhanced by reduction of sea ice extent, subsiding and warming permafrost landscapes, along with increasing open water periods, storminess, air and sea surface temperatures, absolute and relative sea level rise, and warmer ocean (Irrgang et al., 2018).

The main focus of this study is to evaluate the applicability of Sentinel-2 multispectral data for the delineation of Arctic coastlines and subsequent calculation of shoreline change rates. Recently, several methods have been proposed and are being developed for the automatic delineation of shorelines. However, the nature of Arctic coasts, with high cloudiness, high variability in turbidity, sea-ice, snow banks, variable cliff heights and increased shading due to low solar altitude, poses significant challenges to automatic algorithms.

We compare the application of different automatic shoreline delineation algorithms with validation data based on the manual identification of the shorelines. The latter is done on the Sentinel-2 images and using very high-resolution Pleiades (CNES/Airbus) imagery. The study area is located on the Beaufort Sea coast stretching from the Alaska-Yukon border to Banks Island.

The manual and automatic shoreline delineation with Sentinel-2 imagery comprise two years: 2016 and 2020. Pleiades analysis was done for 2018, 2020 and 2021. The automatic methods that were tested are the WaterDetect (Cordeiro et al., 2021) and XGBoost (Chen et al., 2016) methods. The results from the performance assessment of the automatic methods and identification of the limiting factors and errors associated with sea and atmosphere conditions will be used to create recommendations for improving the development of automatic coastal classification algorithms for Arctic coasts.

The Grain of the Plains Remains: Widespread Northwest-Southeast Ridgelines and Associated Oriented Landforms, Northern Interior Plains, USA 
Authors: Joeckel Robert Matthew , Hanson Paul , Korus Jesse
Published: June 2022

We have mapped >200,000 roughly northwest-southeast-oriented ridgelines, >10,000 deflation basins, the outlines of small dune fields, and associated, presumptively aeolian landforms across an area of 660,000 km2 between 39° and 48° N and 93° to 108° W in the USA.  Our study area lies east of the Rocky Mountain front and, effectively, west of the Late Pleistocene limit of Laurentide glaciation. It includes parts of Iowa, Missouri, Kansas, Nebraska excluding the Sand Hills, Colorado, Wyoming, South Dakota, North Dakota, and Montana.  The oriented ridgelines lie within the western periphery of the Central Lowlands in the Dissected Till Plains (where multiple pre-Illinoian ice advances occurred) and across a large part of the Great Plains (including some of the glaciated Coteau Slope in North Dakota). Most of the ridgelines are developed on Cretaceous, Paleogene, and Neogene sedimentary rocks and Pleistocene loesses.  Northwest-southeast-oriented ridgelines are a prominent, and in some cases the dominant component (e.g., on the Pierre Shale in northernmost Nebraska and much of western South Dakota, and on loess in parts of western Iowa and east-central Nebraska) of local to regional landscapes.  Thus, the ridges impart a pronounced geomorphic “grain.”  Oriented ridgelines may be sharp- or broad-crested, straight to slightly sinuous, and they range in length from 0.1 to 15 km.  We interpret the oriented ridgelines on pre-Pleistocene strata to have resulted primarily from aeolian erosion.  Those on loess may have been produced by a combination of erosion and deposition.

Multiple lines of evidence support a hypothesis that the oriented ridgelines were produced chiefly by wind erosion during the Late Pleistocene.  The study area encompasses many Pleistocene–Holocene dune fields, including the largest dune field in the Western Hemisphere (Nebraska Sand Hills). There are also widespread dust deposits, such as the Peoria Loess.  Erosional features, ranging from local ventifacts to widely distributed deflation basins, that have already been identified as aeolian features in the study area.  Moreover, the orientations of deflation-basin axes, the long axes of small dune fields, and other presumptively aeolian features tend to accord with the general trend of the oriented ridgelines, suggesting a commonality in their geomorphic origins.  Additionally, other authors have interpreted MIS/OIS (29–14 ka), at the end of the Pleistocene, as a time of dry, windy, and dusty conditions, during which vegetation cover was reduced at least locally in the interior of North America.
The granite landscape of the Penedos de Pasarela and Traba (Costa da Morte, Galicia, Spain) 
Authors: Perez-Alberti Augusto
Published: June 2022

The granite massif of Pasarela and Traba is in Costa da Morte (Galicia, NW Spain) and their orientation is North-South. In this zone dominate biotite granodiorite (late hercinic age), whose main mineral is potassium rich feldspar. This is a granite material with a great uniformity and coarse grain, which distinguishes it from two micas granites (further east). The officially called Penedos de Pasarela e Traba was declared on January 12, 2009, as protected landscape by the autonomous government of Galicia.

For the present investigation, a 2-meter resolution digital elevation model has been created. With it and with orthophotos of 27 cm resolution, slope maps have been constructed and 7035 polygons with very varied limits and 1785 fracture lines have been drawn. The surface area of the first ones has been obtained and with the second ones a fracture density map has been elaborated.  All this, together with field work, has made it possible to identify and geolocate 73 singular geoforms with geometric, anthropomorphic or zoomorphic designs that make the Penedos a place of international importance.

Bauxitization scaffolded by quartzites 
Authors: S. de Campos Daniela , S. Monteiro Hevelyn , M. Vasconcelos Paulo , A. Farley Kenneth , Vidal-Torrado Pablo
Published: June 2022

Bauxites associated with quartzite karsts have not been previously reported.  In the Southern Espinhaço Range, Southeastern Brazil, bauxitic duricrusts reveal a unique geological-geomorphological setting. The spatial relationship between hematite-phyllites and quartzites and their different strengths play a key role in the development of thick bauxite profiles. The quartzites, resistant to physical and chemical denudation, scaffold the more easily eroded phyllites, protecting the later from physical erosion and allowing long-term – tens of millions of years – chemical weathering to transform phyllites into bauxites. We investigate the geochemical, mineralogical, geochronological and micromorphological signatures of bauxites in order to reconstruct their evolutionary history. Our data reveal periods of intense aluminum and iron dissolution-precipitation triggered by the strong bioturbation, revealing a crucial role for vegetation in bauxite evolution. (U–Th)/He geochronology of Al-goethite reveals bauxitization peaks in the Upper Miocene and Lower Pleistocene, during periods of higher rainfall. We identify a ferruginous duricrust that preceded bauxitization, suggesting perhaps an even more protracted history of weathering, now partially erased by the later-stage bauxitization. Our findings show that the elevated landscape positions and effective drainage into the exposed bedrock were crucial for ferruginous duricrusts to be chemically dismantled, leaving essentially a bauxitic duricrust residue. The chemically and mechanically resilient quartzites of the Southern Espinhaço Range were the main scaffolds that permitted bauxitization of the hematitic phyllites. A new model of bauxitization scaffolded by quartzites is revealed by this study.
Future storylines of landslide susceptibility in the Styrian Basin, Austria. Accounting for environmental change and uncertainties

Published: June 2022

With changing environmental conditions, the risk of landslides will also change. For the Styrian basin, Austria, we investigate how storylines of climate and land use/land cover change may affect future landslide susceptibility (2071-2100). Our analysis is based on two extreme rainfall events in Styria in 2009 and 2014, which triggered more than three thousand landslides causing a major threat to the local population and significant damage to settlements and infrastructure.

Furthermore, while the number of studies analysing the impact of climate and land use change on landslide dynamics is rising, the assessment of their uncertainties is still often neglected. However, the quantification of uncertainties is not only essential for the development of business strategies and policy interventions, but also for increasing transparency and confidence in scientific analysis. Therefore, we additionally analyse the joint contribution of climate change uncertainty and landslide model uncertainty for the developed storylines of landslide susceptibility.

We found for the worst-case storyline (4 K warming scenario) a substantial increase in highly susceptible areas due to much heavier rain. However, the estimated prediction uncertainties were generally high in all storylines. We discovered that the parametric landslide model uncertainty was of the same order as the climate scenario uncertainty, while uncertainties due to internal climate model variability were negligible. With an improved availability of event-based landslide inventories and high-resolution ground data, uncertainties in storylines of landslide susceptibility may be reduced.
Soil erosion after the 2017 forest fire of Braga (Portugal)
Authors: Vieira António , Bento Gonçalves Antonio , Novais Jorge , Folharini Saulo , Rocha José
Published: June 2022

Soil erosion promoted by rainfall constitutes a major land degradation process. The occurrence of heavy, often localized, precipitation can cause severe erosion and increase the risk of flash flooding and debris flow. However, its occurrence in very specific situations, such as in areas affected by forest fires, changes significantly the behavior of the different factors and processes, as well as the conditions related with erodibility, contributing for an increasing erosion risk.

Several studies have shown strong and sometimes extreme responses in runoff generation and soil loss following fires, especially during the first 4 to 6 months after the fire. In Portugal this is a period of greatest vulnerability to erosion because of the maximum fire potential in summer (July–August) and the likelihood of intense post-wildfire rainfall the following autumn–winter (November–January).

In fact, forest fires produce a major impact on soil, being considered the major cause of soil degradation and desertification, and promoting significant changes on landscape features and landforms.

In the present study case, following the October 2017 forest fire in Braga and the subsequent storm that affected the burnt area, it was possible to identify the erosive processes that occurred and their consequences, which are presented in this work. The visual assessment of the erosive action on the slopes in the burned areas detected the development of critical areas with a higher concentration of erosion, in the areas most affected by fire, with steep slopes and where the anthropic action is more active (unpaved forestall roads and other anthropic infrastructures). These effects were surveyed with UAV and modeled in GIS environment. Erosion plots were also used to quantify soil erosion. The evidence found in the area affected by the fire in Braga and in the city itself demonstrates the serious impacts of forest fires on the soil, namely in terms of its erosion and degradation, and consequent impacts on the downstream areas, especially when it comes to urban areas.

Modelling of the outburst flood hydrograph due to the moraine lakes outbursts
Authors: Pryakhina Galina , Rasputina Valeriia , Popov Sergey
Published: June 2022

Catastrophic outburst floods are formed due to the destruction of moraine dams of the periglacial lakes. Outburst floods are dangerous hydrological phenomena that cause the large material damage and often lead to human losses. These dangerous hydrological phenomena are sudden and fleeting due to this the organization of observations is extremely difficult and unsafe. To study these hydrological phenomena the methods of mathematical modelling and physical modelling are most often used. This paper presents a methodology developed by the authors for calculating the outburst flood hydrograph, which is formed during the destruction of an earth dam due to water overflow through the crest. The methodology was verified using the results of physical experiments carried out on a special experimental setup and in natural conditions. The quantitative characteristics of outburst floods obtained as a result of physical experiments were used for comparison with the data obtained in mathematical modelling. Comparison of the simulated outburst flood hydrographs with obtained hydrographs as a result of physical experiments showed their convergence. The paper also presents the results of numerical experiments, which allowed to obtain the dependence of the discharge on the initial size of the breach, the specific gravity of the material from which the dam is built, the percentage of clay in this material and the roughness coefficient value. The results of the work were considered satisfactory and demonstrated the efficiency of the calculation method.

How to constrain the uplift history and landscape evolution processes of the youthful stage mountain by the landscape evolution model?
Authors: Geng Haopeng , Cai Shun , Pan Baotian
Published: June 2022

Starting in the 1990s，geoscientists began to translate many geomorphic processes into computer program (landscape evolution models LEMs) to simulate the form and characteristics of Earth surface. How to correctly evaluate the similarity of simulated and realistic terrain is a main problem to verify the accuracy of reproducing the landscape evolution. In the process of landscape evolution, the landform experiences vertical variation and horizontal spatial topological structure variation. The lack of effective characteristic to compare the similarity of different topographies in two dimensions has been the major problem restricting the application of LEMs in geomorphic application. We speculate that the appropriate topographic characteristics group can measure the similarities of simulated and realistic terrain in two dimensions, and constrain its landscape evolution processes by LEMs. A region with a uniform climate and with well-defined geological and geomorphic processes is well suited to verify the foregoing speculation via numerical simulation. The arid region of North-West China (Hexi Corrdior and northern piedmont of the Chinese Tian Shan) has an arid climate with spatially uniform precipitation, and is subjected to relatively simple erosional processes. Moreover, there are many youthful stage mountains with obvious difference form and characteristics. which indicates that different tectonic activity is the main factor for their difference surfaces. First of all, we have analyzed difference topographic characteristics of four youthful stage mountains (the Jintanan Mt., Heli Mt. around Hexi Corrdior; the Manas Ant. Huoerguosi Ant. in northern piedmont of the Chinese Tian Shan) and simulated its evolution by Landlad. Then, with the topographic characteristics group (uniform valley spacing, local relief, outlet spacing), we compared the realistic and simulated terrain for different model ages. Finally, based on the similarity of the terrains, we estimated the timing of the initial uplift and the rock uplift rate of those mountains. The results are consistent with previous geological and geomorphological records from these youthful stage mountains. Our findings demonstrate that LEMs combined with topographic characteristics are a reliable means of constraining the timing of the initial uplift and the rock uplift rate of the youthful stage mountain. Our approach has the potential to be applied in other youthful stage mountains and to become widely-used tool in tectonic geomorphology.
Holocene fluvial archives and contributions for the study of prehistoric and protohistoric periods, southern piedmont the Hajar Mountains (Oman)
Authors: Beuzen-Waller Tara
Published: June 2022

In Oman, quaternary climatic fluctuations alternated between humid and arid periods. As humid periods triggered increasing rainfall and fluvio-lacustrine activity, allowing for less restrictive arid conditions, they are a key component in the landscape evolution and in the early human-environment history. Fluvial archives are of great interest for understanding the hydrosystems’ local responses to Holocene regional climatic fluctuations and water ressources availability and reachability. For the Holocene, little data are available in Northern Oman to examine the impact of the Holocene Pluvial Phase on hydrosystems and the timescale of the onset of arid conditions around 5.500 BP. Here, we will present fluvial records from southern part of the Hajar Mountains’ piedmont. Geomorphological mapping, morphostratigraphic analyses of natural and excavated sections, malacological analyses and age-dating supported by OSL and radiocarbon methods provided us a better understanding of aggradations phases in link with fluvial activity and increasing rainfall. Phases of aggradation has been identified between around 11,500 cal. BP, between 6,610 cal. BP and 5,400 cal. BP and around 2,700 cal. BP. We will compare and discuss the hydro-climatic data obtained with fluvial archives to archaeological sites distribution and development of hydraulic system during the Bronze age and the Iron age in several archaeological areas of the southern piedmont of the Hajar mountains (Bisyah, Adam, Al Khashbah)
Two-level assessment of threats to geodiversity and geoheritage
Authors: Kubalíková Lucie
Published: June 2022

Geoconservation is an action of conserving and enhancing geological, geomorphological, hydrological and soil features and processes, sites and specimens. Originally and usually, the geoconservation activities aim at preserving specific sites of Earth-science interest, respectively geoheritage. However, for effective and sustainable management of geodiversity and geoheritage, it is necessary to take into account the surroundings of those sites and undertake the geoconservation measures for wider area. Geoconservation activities involve the care, management, protection and promotion of geoheritage and geodiversity and help to balance the conservation needs and sustainable use of these entities. Nevertheless, despite established legal protection, threats to geoheritage and geodiversity can arise and reaching a compromise can be difficult. Thus, the identification and assessment of threats should be also included in geoconservation activities. In this contribution, the two-level threat assessment is applied and discussed. The first level of threat assessment corresponds to the geoconservation in a strict sense – the method for assessing the threats is based on the already used criteria within geosite/geomorphosite concept. The second level of threat assessment corresponds to the geoconservation in broader sense and here, it is represented by Risk Assessment Matrix which assess the threats within wider area. Using both approaches provides a complex view on the threats to geodiversity and geoheritage in a study area and complement each other. The concept was applied in an area situated in the outskirts of a large city (Hády Hill in Brno, Czech Republic), where threats, risks and possible conflicts of interest were identified and assessed. The results offered a framework for future management proposals that may contribute to the balance of the different demands and more effective geoconservation management in the study area.

Probióticos podem ser usados como adjuvante ao tratamento periodontal?
Authors: Lourenço Talita Gomes Baêta , Medeiros Fernanda Jurema
Published: June 2022

A microbiota oral em condições de saúde está em equilíbrio entre hospedeiro e microrganismos, porém diversos fatores podem levar ao desequilíbrio dessa relação, associada ao desenvolvimento e progressão de doenças orais, como as doenças periodontais (DP). O controle mecânico e químico do biofilme dental é o principal método de prevenção e tratamento dessas doenças, muitas vezes somado ao uso de antimicrobianos. Considerando a atual preocupação sobre o uso indiscriminado de antimicrobianos e a natureza disbiótica da DP, estratégias preventivas e terapêuticas visando o equilíbrio ecológico da microbiota oral vem sendo exploradas, dentre elas, o uso de probióticos. Todavia, pouco é sabido sobre a real eficácia deles no tratamento das infecções orais. O objetivo deste trabalho foi realizar uma revisão de literatura sobre o uso de probióticos como adjuvante ao tratamento da DP. Foi realizada a pesquisa bibliográfica nos bancos de dados Scientific Eletronic Library Online (SciELO), Biblioteca Virtual em Saúde (BVS), US National library of Medicine National Institutes of Health (PubMed) e Google Acadêmico, com os descritores “Doença Periodontal” e “Probióticos”, de estudos clínicos realizados entre 2011 e 2021. A busca resultou em 49 estudos clínicos e após leitura completa 33 foram selecionados, atendendo aos critérios de inclusão. De forma geral, o uso adjuvante de probióticos parece trazer algum benefício clínico adicional ao tratamento e, esse efeito pode ser observado também nos parâmetros microbiológicos. No entanto, os protocolos de tratamento e os desfechos observados nos estudos são extremamente variáveis, sendo difícil determinar o melhor protocolo de administração dos probióticos.

Published: June 2022

Sand mining which been a major contributor to economic growth and development has turned out to be a source of environmental degradation based on the fact that the renewal rate of sand is lower than its rate of consumption. This study reviewed the universe, earth, and finally focused on sand as one of earth’s most consumed natural resources after water. The study shows how countries of the world engage in sand exportation to grow their economy by creating job opportunities to both skilled and unskilled individuals in the society. Key issues surrounding the ethical conduct of sand mining were discussed in details by angling towards environmentalists’ view that are of the opinion that sand mining activities ought to be drastically reduced and strictly regulated in order to save the depleted state of the ecosystem. The study was anchored on the Green theory which emphasizes that there is a need to regulate the overconsumption of shared natural resources such as land, water, and sea animals by individuals and organizations.

A functional classification analysis of government spending multipliers
Authors:   Bank of Greece, Konstantinou Panagiotis Th. , Partheniou Andromachi , Tagkalakis Athanasios
Published: June 2022

Using a panel of 33 OECD countries we estimate government spending multipliers for 11 different categories (functions) of spending: General Public Services, Defense, Public Or- der and Safety, Transport & Communication, Economic Services, Environment Protection, Housing and Community Amenities, Health, Education, Recreation, Culture and Religion, and Social Protection. We also account for variations in the state of the business cycle (recession vs expansion). Our results suggest that Public Services, Defense, Public Or- der, Transport & Communication, Health, Recreation and Education produce positive and high multipliers, whereas multipliers for Economic Services are negative, and multipliers for Environmental Protection, Housing and Social Protection are insignificant. In addi- tion, multipliers for Public Services, Defense, Public Order, Transport & Communication, Health, Recreation and Education are higher in recession than in expansion.
