Introduction: Since the origin of the COVID-19 pandemic, many consequences have been constantly faced by the population. The threat related to the numbers of contamination, accentuated by catastrophic reports of serious illness or death, added to the scenes shown in the media of hastily built cemeteries and crowded hospitals can have a direct effect on the mental health of the population, generating fear and insecurity. Adolescents, when infected with the coronavirus, have the same clinical symptoms as adults. In this context, when it comes to worsening health, mental health problems and domestic violence were the main predisposing factors that caused damage to well-being, societal characteristics that should influence the individual and collective health of adolescents. Therefore, knowing the relevance of this theme, this study aimed to identify in the literature the characteristics of mental disorders that affect adolescents during the pandemic. Methodology: This is a descriptive, exploratory, integrative literature review, carried out from a bibliographic survey in the following databases: Latin American and Caribbean Literature on Health Sciences (LILACS) and Scientific Electronic Online Library (SCIELO). Results and Discussions: Clinically, adolescents are proposed to develop the same symptoms of mental disorders as adults during the period of isolation. The context of the economic crisis, social isolation and the weakening of health services are related as the main factors that contributed to the development of mental illnesses such as depression, anxiety, self-mutilation and panic syndromes. Final considerations: Therefore, it became evident that the main disorders that affect young people and adolescents during the period of isolation, resulting from the COVID-19 pandemic, are ansiety and depression. In addition, the main causes that trigger such problems are isolation measures and family problems.

Introduction: Dentistry currently plays an important role in the different therapeutic phases against cancer, whether in the phase that precedes cancer treatment, where a previous evaluation can effectively reduce complications arising from infectious or inflammatory processes of oral origin, which can exacerbate during treatment. and after neoplastic treatment, or in the prevention of oral sequelae that occur during and after radiotherapy treatment. Objectives: To carry out a literature review on the oral manifestations resulting from radiotherapy, addressing the management and treatment of complications. Materials and methods: This is a descriptive work with a qualitative aspect of literature review, where scientific articles and books were used as research sources. After applying the inclusion and exclusion criteria, 96 studies were found and 22 were selected. Results and discussion: The oral manifestations resulting from radiotherapy are well recognized in the literature and the most frequent are oral mucositis, xerostomia, loss of taste, trismus and osteoradionecrosis. Conclusion: Adequacy of medium before radiotherapy treatment is widely recommended in the literature as a prevention of oral manifestations resulting from cancer treatment. In addition, dental follow-up of the patient during cancer treatment is necessary, for this, it is recommended that the dentist be part of the multidisciplinary oncology team. Thus, combining prevention with follow-up, it is possible to obtain a reduction in the rates of involvement of these manifestations and, consequently, less interruption of treatment and an improvement in the quality of life of radiotherapy patients.

Introduction: Most deaths caused by Covid-19 are of people over 60 years old, in Brazil, in 2021, this population represents 67.9% of the dead, due to complications from the virus. Faced with this, people in isolation suffered several effects on their health, especially with regard to mental health, such as sleep disorders, concentration on daily tasks, the appearance of intrusive thoughts, feelings of hopelessness, boredom, loneliness, anxiety and depression. Thus, the elderly stand out as the group most affected by mental disorders, with emphasis on depression, which is an aggravating factor for health, triggered by the consequences of social withdrawal, quarantine, the economic crisis, domestic accidents such as falls and high numbers of deaths caused by covid. The objective of this study was to identify scientific evidence in the literature about the impacts of social isolation on the mental health of the elderly during the pandemic, as well as recommendations to prevent depression. Method: This is a descriptive and exploratory study, of the integrative literature review type, carried out in the following databases: LILACS, BRISA AND SCIELO. Results and Discussions: With an analysis of the literature, it was evidenced that depression was one of the biggest impacts caused by the pandemic on the health of the elderly, resulting from sequelae caused by social isolation and the pandemic. Allied to this, domestic accidents, such as falls, are also classified as a predisposing factor for depression during social isolation, given that many elderly people live alone or spend more time exposed to risky situations in their homes, being more likely to fall into their homes and cause fractures. In this aspect, psychic disorders were intensified especially in these individuals in the current pandemic moment, the multimorbidities present in the elderly have a strong impact on the increase of mental health problems, causing emotional distress in these individuals. In this process, recommendations to support the elderly are essential with regard to predisposing factors for depression. Final Considerations: The study highlights the association of depression and the worsening of psychiatric pathologies related to the process of social isolation resulting from the pandemic, associated with the high rate of falls present in this population.

Published: July 2022

Galactosemia is an inborn error of metabolism, caused by autosomal recessive deficiency in enzymes that convert galactose to glucose. Excess galactose is converted in the liver to galactitol (alcohol of elevated toxicity), responsible for neurologic, hepatic, gastrointestinal manifestations, in varying degrees according to the mutation developed. OBJECTIVE: To observe the prevalence of galactosemia in patients with DM1 and DM2. METHODS: Group 1: patients with DM2, male gender (n=9); female gender (n=11). Group 2: patients with DM1, male gender (n=7); female gender (n=3). Group 3: Non-diabetics (n=30). Clinical follow-up of these patients included laboratory tests and imaging studies. RESULTS: There was a higher prevalence of galactosemia in DM2 patients, in comparison to DM1 patients and non-diabetics (21.66 >3.33 >1.66). The prevalence of galactosemia in DM2 patients was higher than that found in DM1 patients (2166 >3.33). CONCLUSION: Our study found a higher prevalence of galactosemia in DM2 when compared to DM1 and a healthy population.

Abstract: Regardless of their topology, areas located at springs are considered permanent preservation areas in Brazil. Such areas may or may not be covered by native vegetation and contribute to the conservation of local natural resources through the determination of areas that are improper for land use in order to maintain the original plant coverage. Urban environments suffer degradation due to the lack of planning and basic sanitation. The aim of the present study was to analyze the permanent preservation area on the banks of the Salgado River in the urban zone of the municipality of Aurora, state of Ceará, Brazil. A case study was conducted involving the following steps: bibliographic review, determination of the study area, selection of indicators, on-site visits, identification of problems and the presentation of a proposed solution. The results indicated that the banks of the river were highly degraded due to urbanization and the removal of vegetation. The water resource was contaminated due to the construction of houses, enterprises and a public square in the protected area and was contaminated by residential sewage and the sewage system itself as well as solid and liquid waste from means of transportation, noise pollution and light pollution, which hinder the habitation and movements of endemic animals. In conclusion, the area limits and treatments necessary for the permanent protection area stipulated by law have not been successful due to the continued process of appropriation for urbanization. Thus, human activities cause harm to the natural environment and the population itself, exposing these elements to diseases and floods.
DESCARTES AND THE BEAUTY IN MATHEMATICS

Published: July 2022

The history of mathematics shows that its foundation, as well as its development, were given slowly, at first without much rigor, but always with creativity. The axiomatic method, theorems, propositions and rational concepts, logically arranged, were the greatest successes achieved by this science. However, mathematics is also characterized by a singular elegance, not always obvious and little explored. Considering that it is one of the bases of scientific spread and it is part of the historical and cultural structure of society, it is necessary to further deepen this characteristic. In this context, in order to prove the existence of this elegance, or rather, of the beautiful in mathematics, is used the works of philosophers and mathematicians who stood out during the elaboration of this science. The focus is on Descartes’ work The Geometry, composed of three parts. In one of them the philosopher affirms that a certain theorem is very beautiful. Thus, the starting point will be to explore the concept of beauty in Plato, towards the beautiful in mathematics.

Published: July 2022

The teaching of physics is approached in this article with one of the most crucial points for learning, the methodologies and techniques. The points that lead to students’ lack of interest: mathematization of content, lack of infrastructure, insufficient workload. The predominant problem in this area of ​​education and methods or theories are presented, proposed by Ausubel (1980), Libâneo (2006), Lima (2016), Moreira (1982) and Silva (2018) to alleviate these factors. The present work had as research focus to adapt which of the pedagogical trends is the best to be adopted when it comes to the teaching of thermal physics for high school students. With the analysis, the Progressive Renewed Liberal Tendency proved to be the most appropriate, for valuing experimentation, active study and previous knowledge, the latter defended by Ausubel in his Theory of Learning, where the student captures new information and improves at his own pace. preexisting. However, the research addressed the important contents for the development of learning in the discipline of physics, merging the assumptions by the pedagogical practices studied, where the role of the teacher and the student were the main focus in obtaining means that facilitate learning, coming to verify that both are important and must be complementary, as there will be situations in which one will be more efficient than the others.

Published: July 2022

Amyotrophic Lateral Sclerosis (ALS) represents the most common form of Motor Neuron Disease (MND), which is more frequent in adults and the elderly. The degenerative process of this disease has a complex etiology and is related to several factors. Its symptoms develop from a successive loss of both upper motor neurons (LMN), located in the cerebral cortex, and lower motor neurons (LMN), located in the brainstem and anterior horn of the spinal cord. Its diagnosis is often delayed and its prognosis is not favorable. This work reviewed data on ALS and the Genetic Panel Test arranged in physical and electronic media such as books, virtual libraries and databases. The findings of this study indicate that the genetic panel is extremely important for patients with amyotrophic lateral sclerosis, since it allows the specific evaluation of the genes involved in this disease and their possible gene mutations, in addition to allowing the differentiation in their hereditary and sporadic.

‘Öteki’nin ‘Ben’ Üzerine Düşen Gölgesi: Yabancılaşma
Authors: ÇORAK Ahmet
Published: July 2022

Bu çalışmada, yabancılaşmanın intrapsişik yansımaları üzerine eğilinmiş, odak noktası olarak yabancılaştırıcı şartlar değil yabancılaşmanın kendisi ele alınmıştır. Yabancılaşma olgusu; “bağlantı”, bağlantıyı oluşturan “ögeler”, bu ögeler arasındaki “ilişki” ve bu ilişkilerdeki “kopma” ve sonuçta ortaya çıkan “ayrılma” (separation) ve “mesafe”, yani “ilişkisizlik” kavramları üzerinden incelenmiştir. Benlik/kendilik ile ilişkisi açısından yapılacak olan inceleme ile “bireysel yabancılaşma”nın psişik bir formülasyonuna ulaşmak amaçlanmaktadır.Yabancılaşma durumlarında gerçek kendiliğin farklı derecelerde işlevsiz kalması ve sahte kendilik betimlemelerinin yabancılaşma olgusunu açıklayıcı paralellikler içermesi nedeniyle, birden fazla kendiliğin dinamik ilişkisi üzerinden yabancılaşmanın anlaşılmasının imkânı, araştırılmaya değer bulunmuştur. İlişkisizliğin yerine “mış gibi” ikame edilen çoklu özdeşimler ve taklit, uyumlanmanın (compliance), gerçek kendiliğin deanimasyonu ise yaşamama hissi, güçsüzlük, anlamsızlık gibi yabancılaşma belirtilerinin kaynağı olarak görülmektedir.Kişinin kendisine yabancılaşması, kendilikler arası bir bölünme olduğunu doğrudan ifade etmektedir. Kendiliklerin birbirinden ayrı durma imkânı (disosiyasyon) ise, yabancılaşma olgularında önemli bir açıklayıcı güce sahiptir ancak genellikle psikopatoloji ile sınırlı tutulmaktadır. Çoklu özdeşimlerle, taklit veya çevrenin dayatmalarıyla ortaya çıkan “ötekine ait olan kendilik parçaları”nın etkinleşmesi, “ben”den çalınan ve öznellikte sahnelenen ötekine ait (ego-alien) duyu-duygu-düşünüş-eylem örüntülerinin belirmesine yol açar ve yabancılaşma olarak nitelenir.Bu çalışmada, kendilik tasarımı ile ilişkilendirerek konuya yaklaşım sağlamak amacıyla, zaman zaman Nesne İlişkileri Kuramı’nın yöntemlerine başvurulmuştur. Sonuç olarak Nesne İlişkileri yaklaşımı ile sosyal yabancılaşma kuramlarının sentezinin önemli imkânlar barındırdığı görülmektedir.
Okasyonalizme İtirazlar ve Verilen Cevaplar: Diyalektik Bir Çözümleme
Authors: AKAR Metin
Published: July 2022

Okasyonalizme göre Tanrı, sonsuz iradesi ve kudreti ile evrene sürekli müdahale eder ve bu yüzden evrende var olan bütün sebep-sonuç ilişkilerinin yegâne hakiki nedenidir. Sebep-sonuç ilişkisine dair gözlemlediğimiz bütün failler Tanrısal müdahalenin vesile nedenleridir. Bu makale ilk olarak okasyonalizmin temel iddialarını Gazzâlî ve Malebranche perspektifinden betimleyici bir anlatımla ele almaktadır. Ardından okasyonalizme yapılan itirazları ve verilen cevapları diyalektik bir biçimde analiz etmektedir. Makale, okasyonalizmin iç tutarlılığa sahip bir yaklaşım olduğunu, ancak yapılan itirazlara bu iç tutarlılık perspektifi dışında cevap vermediğini iddia etmektedir. Son olarak makale, çağdaş zihin felsefesi kapsamında okasyonalizmin zihnin ve bilincin doğasına yönelik bilimsel çalışmaları dışladığını ve gizemci bir pozisyonu savunduğunu ortaya koymaktadır.

Authors: TAŞ Fatıma Betül
Published: July 2022

Orta çağın önde gelen Yahudi mezhepleri olan Rabbaniler ve Karailer çeşitli dinî meseleler hakkında birbirlerine eleştiriler yöneltmişlerdir. Karailerin en temel itirazı, Rabbani Yahudilerin Sözlü Tora olarak gördükleri Mişna ve Talmud’un vahiy mahsulü olmasına yöneliktir. Bu hareketin önemli temsilcilerinden biri, 10. asırda Bağdat’ta yaşayan Ya‘kup el-Kirkisânî’dir. Onun kaleme aldığı Kitâbu’l-Envâr ve’l-Merâkıb, Karailikle ilgili günümüze ulaşan en hacimli eserdir. El-Kirkisânî, bu eserde kronolojik olarak Yahudi gruplar hakkında değerli bilgiler vermekte ve onları farklı açılardan eleştiriye tabi tutmaktadır. Eserin en temel gündemlerinden biri, Karailerin muarızları olan Rabbanilerin inanç ve uygulamalarındaki dine aykırı hususları ortaya koymaktır. El-Kirkisânî’nin eleştiri konularından biri de Rabbani kaynaklardaki Tevrat ve çevirileriyle ilgili görüşlerdir. Bu çerçevede Septuagint, Targum Onkelos ve Targum Yonatan hakkındaki Rabbani düşünceleri ele almaktadır. Septuagint’in yazılış hikâyesiyle ilgili Hıristiyan ve Rabbani kaynaklardaki nakilleri eleştiren el-Kirkisânî, Rabbanilerin Septuagint’te Tanrı’nın ilhamıyla değişiklikler yapıldığı iddialarına karşı çıkarak bunu Tanrı inançlarındaki bozukluk olarak nitelemektedir. Targum Onkelos ve Targum Yonatan’daki çeviri hatalarını göstererek Rabbanilerin bu çevirileri ve mütercimlerini yüceltmelerine tepki gösteren el-Kirkisânî, Targum Onkelos’u Tevrat’la birlikte liturjide kullanmalarına da karşı çıkmaktadır. Bu çalışmada, Kitâbu’l-Envâr’daki anlatımlar Rabbani literatürdeki bilgilerle ve Tevrat çevirileriyle karşılaştırılarak incelemeye tabi tutulmakta, aynı zamanda el-Kirkisânî’yi etkileyen İslami fikirler ortaya koyulmaktadır.

Published: July 2022

Abstract. Orographic gravity waves (i.e. mountain waves) can potentially lead to cross-isentropic fluxes of trace gases via the generation of turbulence. During the DEEPWAVE (Deep Propagating Gravity Wave Experiment) campaign in July 2014 we performed tracer measurements of carbon monoxide (CO) and nitrous oxide (N2O) above the Southern Alps during periods of gravity wave activity. The measurements were taken along two stacked levels at 7.9 km in the troposphere and 10.9 km in the stratosphere. A detailed analysis of the observed wind components shows, that both flight legs were affected by vertically propagating gravity waves with momentum deposition and energy dissipation between the two legs. Corresponding tracer measurements indicate turbulent mixing in the region of gravity wave occurrence. For the stratospheric data we identified mixing leading to a change of the cross-isentropic tracer gradient from the upstream to the downstream region of the Southern Alps. Based on the quasi-inert tracer N2O we identified two distinct layers in the stratosphere with different chemical composition on different isentropes. The CO-N2O relationship clearly indicates that irreversible mixing between these two layers occurred. Further we found a significant change of the N2O-Θ-profiles from the upstream to the downstream side above the Southern Alps with different gradients of the N2O-Θ-relation just above the tropopause. A scale-dependent gradient analysis reveals that this gradient change is triggered in the region of gravity wave occurrence. The power spectra of the in-situ measured vertical wind, Θ, and N2O indicate the occurrence of turbulence above the mountains associated with the gravity waves in the stratosphere. The estimated eddy dissipation rate based on the measured three dimensional wind indicates a weak intensity of turbulence in the stratosphere above the mountain ridge. The N2O-Θ-relation downwind the Alps modified by the gravity wave activity provides clear evidence that trace gas fluxes, which were deduced from wavelet co-spectra of vertical wind and N2O are at least in part cross-isentropic. Our findings thus indicate that orographic waves led to turbulent mixing on both flight legs in the troposphere and in the stratosphere. Despite only weak turbulence during the stratospheric leg, the cross isentropic gradient and the related composition change on isentropic surfaces N2O-Θ gradient change from upstream to downstream the mountain unambiguously conserves the effect of turbulent mixing by gravity wave activity before the measurements. This finally leads to irreversible diabatic trace gas fluxes and thus has a persistent effect on the UTLS trace gas composition.

Published: July 2022

Abstract. Long-term monitoring at sites with relatively low
particulate pollution could provide an opportunity to identify changes in
pollutant concentration and potential effects of current air quality
policies. In this study, 9-year sampling of PM10 (particles with an aerodynamic diameter below 10 µm) was performed in a rural background site in France (Observatoire Pérenne de l'Environnement or OPE) from 28 February 2012 to 22 December 2020. The positive matrix factorization
(PMF) method was used to apportion sources of PM10 based on quantified
chemical constituents and specific chemical tracers analysed on collected
filters. Oxidative potential (OP), an emerging health metric that measures
PM capability to potentially cause anti-oxidant imbalance in the lung, was
also measured using two acellular assays: dithiothreitol (DTT) and ascorbic
acid (AA). The sources of OP were also estimated using multiple linear
regression (MLR) analysis. In terms of mass contribution, the dominant
sources are secondary aerosols (nitrate- and sulfate-rich) associated with
long-range transport (LRT). However, in terms of OP contributions, the main
drivers are traffic, mineral dust, and biomass burning factors. There is
also some OP contribution apportioned to the sulfate- and nitrate-rich
sources influenced by processes and ageing during LRT that could have
encouraged mixing with other anthropogenic sources. The study indicates much lower OP values than in urban areas. A substantial decrease (58 %
reduction from the year 2012 to 2020) in the mass contributions from the traffic factor was found, even though this is not clearly reflected in its OP contribution. Nevertheless, the findings in this long-term study at the OPE site could indicate effectiveness of implemented emission control policies, as also seen in other long-term studies conducted in Europe, mainly for urban areas.
Atmospheric visibility inferred from continuous-wave Doppler wind lidar
Authors: Queißer Manuel , Harris Michael , Knoop Steven
Published: July 2022

Abstract. Atmospheric visibility, or meteorological optical range (MOR), is governed by light extinction by aerosols. State-of-the-art visibility sensors, such as employed in meteorological observatories and airports, infer MOR by either measuring transmittance or scattering. While these sensors yield robust measurements with reasonable accuracy (10 % to 20 %), they measure in situ. MOR from these sensors may thus not be representative of MOR further away, for example, under conditions with stratified aerosol types. This includes off-shore sites near the sea surface during conditions with advection fog, sea spray or mist. Elastic backscatter lidar can be used to measure light extinction and has previously demonstrated to be a powerful method to infer visibility. Lidar can measure visibility not just near the instrument, but further away (remotely) and single-ended, whilst capable of measuring profiles of MOR along atmospheric slant paths. Continuous-wave (CW) Doppler wind lidar systems make up one of the most widespread type of elastic backscatter lidar and are typically used in wind resource assessment. Using these existing platforms for remote and single-ended measurement of MOR-profiles could allow for new and valuable applications. However, the low light extinction associated with this type of lidar excludes the use of the extinction coefficient for MOR retrieval, but leaves the backscatter coefficient as a possible proxy for MOR, though with an accuracy expected to be inferior to the former method. We analysed backscatter data from CW wind lidar and co-measured MOR from visibility sensors from two campaigns (Cabauw, Netherlands and Pershore, United Kingdom) and found backscatter from CW wind lidar to be a viable proxy of MOR if calibrated against a visibility sensor. The expected accuracy of the method is low and of order of few kilometres. This means MOR from CW wind lidar could be used in safety uncritical problems, such as assessment of visibility of man-made objects, including wind turbines. The high sensitivity of the lidar backscatter to aerosol type and size distribution could open up additional applications, such as volcanic plume monitoring.
Episodic N2O emissions following tillage of a legume–grass cover crop mixture
Authors: Bressler Alison , Blesh Jennifer
Published: July 2022

Abstract. Nitrogen (N) fertilizer inputs to agricultural soils are
a leading cause of nitrous oxide (N2O) emissions. Legume cover crops
are an alternative N source that can reduce agricultural N2O emissions
compared to fertilizer N. However, our understanding of episodic N2O
flux following cover crop incorporation by tillage is limited and has
focused on single-species cover crops. Our study explores whether increasing
cover crop functional diversity with a legume–grass mixture can reduce pulse
emissions of N2O following tillage. In a field experiment, we planted
crimson clover (Trifolium incarnatum L.), cereal rye (Secale cereal L.), a clover–rye mixture, and a no-cover
control at two field sites with contrasting soil fertility properties in
Michigan. We hypothesized that N2O flux following tillage of the cover
crops would be lower in the mixture and rye compared to the clover
treatment because rye litter can decrease N mineralization rates. We
measured N2O for approximately 2 weeks following tillage to capture
the first peak in N2O emissions in each site. Across cover crop
treatments, the higher-fertility site, CF, had greater cover crop biomass,
2-fold-higher aboveground biomass N, and higher cumulative N2O
emissions than the lower-fertility site, KBS (413.4±67.5 vs. 230.8±42.5 g N2O-N ha−1; P=0.004). There
was a significant treatment effect on daily emissions at both sites. At
CF, N2O fluxes were higher following clover than the control 6 d after
tillage. At KBS, fluxes from the mixture were higher than rye 8 and 11 d
after tillage. When controlling for soil fertility differences between
sites, clover and mixture led to approximately 2-fold-higher N2O
emissions compared to rye and fallow treatments. We found partial support
for our hypothesis that N2O would be lower following incorporation of
the mixture than clover. However, treatment patterns differed by site,
suggesting that interactions between cover crop functional types and
background soil fertility influence N2O emissions during cover crop
decomposition.

Abstract. Mineral dust contributes up to one-half of surface aerosol loading in spring over the southwestern U.S., posing an environmental challenge that threatens human health and the ecosystem. Using the self-organizing map (SOM) analysis, we identify four typical dust transport patterns across the Sierra Nevada, associated with the mesoscale winds, Sierra-Block-Jets (SBJ), North-Pacific-High (NPH), and long-range cross-Pacific westerlies, respectively. We find dust emitted from the Central Valley is persistently transported eastward, while dust from the Mojave Desert and Great Basin influences the Sierra Nevada during mesoscale transport occurring mostly in the winter and early spring. Asian dust reaching the mountain range comes either from the west through straight isobars (cross-Pacific transport) or from the north in the presence of NPH. Extensive dust depositions are found on the west slope of the mountain, contributed by Central Valley emissions and cross-Pacific remote transport. Especially, the SBJ-related transport produces deposition through landfalling atmospheric rivers, whose frequency might increase in a warming climate.
VLT/SPHERE imaging survey of D>100 km asteroids: Final results and synthesis

Abstract

Until recently, only three large main belt asteroids, Ceres, Vesta and Lutetia, had been imaged with a high level of detail, as they were visited by the space missions Dawn and Rosetta of NASA and the European Space Agency, respectively. The previously small number of detailed observations of asteroids meant that, until now, key characteristics such as their 3D shape or density had remained largely unknown. Between 2017 and 2019, we have been filling this gap by conducting a high-angular-resolution imaging survey of 42 large main-belt asteroids with VLT/SPHERE (ESO large programme; PI: P. Vernazza; ID: 199.C-0074), sampling the main compositional classes. These observations have allowed to cast some light on the following fundamental questions:

– What is the diversity in shape among large asteroids and are the shapes close to equilibrium?
– How do large impacts affect asteroid shape?
– What is the bulk density of large asteroids and is there a relationship with their surface composition? Is there any evidence of differentiation among those bodies?
– Is the density of those bodies that are predicted to be implanted bodies from the outer Solar System (P/D-types) compatible with that of small (D ≤ 300 km) trans-Neptunian objects?
– What physical properties drive the formation of companions around large asteroids?

Importantly, our survey along with previous observations provides evidence in support of the possibility that some C-complex bodies could be intrinsically related to IDP-like P- and D-type asteroids, representing different layers of a same body (C: core; P/D: outer shell). We therefore propose that P/ D-types and some C-types may have the same origin in the primordial trans-Neptunian disk. The main belt would thus host a population of former TNOs much more important than the one previously considered, consisting solely of P and D-type bodies.

Here, we will present an overview of the results obtained from this survey ([1]) with a specific focus on the origin of a large fraction of the asteroid belt (typically C, P and D-type bodies).

Historical and future weather data for dynamic building simulations in Belgium using the regional climate model MAR: typical and extreme meteorological year and heatwaves

Abstract. Increasing temperatures due to global warming will influence
building, heating, and cooling practices. Therefore, this data set aims to
provide formatted and adapted meteorological data for specific users who
work in building design, architecture, building energy management
systems, modelling renewable energy conversion systems, or others
interested in this kind of projected weather data. These meteorological data
are produced from the regional climate model MAR (Modèle
Atmosphérique Régional in French) simulations. This regional model,
adapted and validated over Belgium, is forced firstly, by the ERA5 reanalysis,
which represents the closest climate to reality and secondly, by three Earth system models (ESMs) from
the Sixth Coupled Model Intercomparison Project database, namely,
BCC-CSM2-MR, MPI-ESM.1.2, and MIROC6. The main advantage of using the MAR
model is that the generated weather data have a high resolution (hourly data
and 5 km) and are spatially and temporally homogeneous. The generated weather
data follow two protocols. On the one hand, the Typical Meteorological Year
(TMY) and eXtreme Meteorological Year (XMY) files are generated largely
inspired by the method proposed by the standard ISO15927-4, allowing the
reconstruction of typical and extreme years, while keeping a plausible
variability of the meteorological data. On the other hand, the heatwave
event (HWE) meteorological data are generated according to a method used to
detect the heatwave events and to classify them according to three criteria
of the heatwave (the most intense, the longest duration, and the highest
temperature). All generated weather data are freely available on the open
online repository Zenodo (https://doi.org/10.5281/zenodo.5606983,
Doutreloup and Fettweis, 2021) and these data are produced within
the framework of the research project OCCuPANt
(https://www.occupant.uliege.be/ (last access: 24 June 2022)​​​​​​​ – ULiège).
The soil heat flux sensor functioning checks, imbalances' origins, and forgotten energies
Authors: Zawilski Bartosz M.
Published: July 2022

Abstract. Soil heat flux is an important component of the surface energy
balance (SEB) equation. Measuring it requires an indirect measurement. Every
used technique may present some possible errors tied with the utilized
specific technique, soil inhomogeneities, or physical phenomena such as
latent heat conversion beneath the plates, especially in desiccation cracking
soil or vertisol. The installation place may also induce imbalances.
Finally, some errors resulting from the physical sensor presence, vegetation
presence, or soil inhomogeneities may occur and are not avoidable. For all
these reasons it is important to check the validity of the measurements. A
quick and easy way is to integrate results over 1 year. By consideration
of the inert core internal energy conservation law, it is shown that the
corresponding integration should be close to zero after a necessary
geothermal heat efflux subtraction. However, below-plate evaporation and
vegetation-absorbed water or rainwater infiltration may also contribute
to the observed short-scale and/or long-scale imbalance generating
convective heat fluxes not sensed by the heat flux sensors. Another energy
source is usually not included in the SEB equation: rainfall or irrigation.
Yet its importance for short- and long-term integration is notable. As an
example, the most used sensor, soil heat flux plates (SHFPs), is given.
