Résumé :

L’ εὕρησις del fuoco nell’Antica Grecia è generalmente abbinata al mito di Prometeo. Ma nelle fonti antiche sono presenti numerose tracce di una narrazione mitica secondo cui l’origine del fuoco era da ricondurre anche a Gaia e alla terra. Tale narrazione mitica sembra presentare una stretta connessione con dati ed esperienze appartenenti al vissuto dell’uomo greco, per il quale Gaia / la terra risulterebbe connessa a funzioni ampie e fondamentali.

Résumé :

POPOLI, CLIMA ED ALLUVIONI: TEORIA, PROGETTO DI RICERCA E NUOVI DATI SEDIMENTOLOGICI E STRATIGRAFICI DALL'ETRURIAQuesto lavoro presenta il progetto di ricerca, i dati stratigrafici e la datazione preliminare (ceramica e paleomagnetica) di un nuovo studio sull'alluvione regionale in Etruria. Le mutevoli relazioni tra popolazione, uso della terra ed erosione nel Mediterraneo vengono discusse allo scopo di mettere in discussione alcune tradizionali ipotesi eco-demografiche. I risultati preliminari indicano un cambiamento da fiumi lateralmente mobili che erodevano e depositavano sabbia e ghiaia durante il periodo Romano, ad una rapida alluvione formata da silt sabbioso tra il tardo medioevo ed il periodo rinascimentale. Il silt sabbioso superficiale tende ad ispessirsi andando da nord a sud e si pensa che ciò sia più probabilmente dovuto all'intensificazione dello sfruttamento del suolo piuttosto che a variazioni climatiche fra diverse aree dell'Etruria.

Résumé :

This article is an attempt to learn from the struggle for identity in early Christianity. Since its birth from the womb of Judaism, Christianity was challenged to redefine its identity, rooted as it was in Judaism vis-à-vis the influence of Hellenization. Such a journey into unknown territory (terra incognita) unavoidably led to the birth of new identity which, on the one hand, remained an integral part of its original matrix, but at once challenged its exclusive character. In this overview, two main examples of reinterpretation are presented to illustrate the case, first, by Paul who radically reinterprets Torah and the identity of God's people in Christ, and second, by the author of 1 Peter who reinterprets the identity of "Christianos" as "aliens" and "exiles" in their Graeco-Roman milieu. As can be learned from these examples, negotiation, and renegotiation are an inevitable necessity when Christianity penetrates new territories in its encounter with the "other", in order to root itself in new terra incognita.

Résumé :

A tese do “marco temporal” defende que somente os povos indígenas que comprovarem que possuíam as terras ou que seus ancestrais as habitavam em 05 de outubro de 1988, data da promulgação da Constituição, teriam direito a demarcação das terras. Essa tese, não leva em conta as diversas etnias, povos, línguas e culturas que existem espalhadas pelo Brasil. Além do mais, o conceito de posse para os povos indígenas é completamente diferente do conceito de posse trazido pelo Código Civil, pois, para o indígena, a conservação da terra é um modo de vida, que garante a subsistência e preservação da cultura indígenas, através da preservação da floresta. Diferentemente, do conceito trazido pelo Código Civil, que mercantiliza a terra para exploração de seus recursos naturais. É preciso lembrar que essas terras pertencem aos povos originários, eles são os reais donos das terras brasileiras, de modo que, não há que se falar em reintegração de posse em favor dos fazendeiros, e, ainda, caso houvesse uma eventual privatização das terras indígenas, esses povos deveriam ser indenizados, além de receber pela exploração econômica de suas terras. Portanto, é preciso distinguir os tipos de terras ancestrais, e a importância de sua regularização. Além do mais, a jurisprudência da Corte Interamericana corrobora o entendimento de que não deve existir um marco temporal para a ocupação indígena, tendo em vista que, ela é anterior a criação do próprio Estado Brasileiro.

Résumé :

Cenários de mudança de uso e cobertura da terra na Amazônia são necessários para subsidiar decisões que podem evitar a emissão de milhões de toneladas de CO2 para a atmosfera. Portanto, é importante avaliar modelos que visam a geração de cenários futuros. O atual estudo avaliou cenários gerados para o período 2011-2017 em Roraima, norte da Amazônia. Comparou-se o desmatamento simulado com os dados de satélite do PRODES. O mapeamento compreendeu (i) uma Área de Uso Silvo-pastoril – AUS (excluindo terras indígenas, unidades de conservação e não-floresta) intersectada com (ii) uma grade de nove (9) células de 10.000 km2 (100 × 100 km) para avaliações. O cenário de 2013 apresentou a maior similaridade (55,2%) com o mapa correspondente do PRODES. Apesar das divergências entre o desmatamento simulado nos cenários e o desmatamento oficial, no geral, as avaliações demonstraram a validade do modelo e a sua habilidade para gerar cenários que representam, de forma realística, o desmatamento ocorrido em Roraima no período analisado.

Résumé :

Em 2014 comemora-se os 50 anos do Estatuto da Terra (Lei no. 4.504/1964). Editado no início da ditadura militar, o Estatuto da Terra foi a fórmula encontrada para conter a pressão vinda do campo que reivindicava uma política governamental com fulcro na Reforma Agrária. Embora principalmente concebido visando á distribuição de terras na Região Norte, após a redemocratização, em 1985, os movimentos campesinos mostraram-se presentes nas cinco regiões do país, demonstrando que a luta pela terra ocupava todo o território nacional. De acordo com o Instituto Nacional de Colonização e Reforma Agrária (INCRA), até 2013 foram assentadas no Brasil 1.288.444 famílias nas regiões Norte, Nordeste, Centro-Oeste, Sudeste e Sul, incorporando ao programa de reforma agrária uma área de 88.197.147 ha. O mais grave problema resultante deste modelo de ocupação de terras foi o desmatamento descontrolado nos assentamentos com o objetivo de converter o uso do solo para atividades agropecu7aacute;rias, o que significou um drástico incremento no índice nacional de desmatamento. Neste contexto, o Instituto Nacional de Colonização e Reforma Agrária (INCRA) criou o Plano de Combate e Alternativas ao Desmatamento Ilegal em Assentamentos da Amazônia Legal, denominado de Programa Assentamentos Verdes, que, juntamente com as Resoluções do Conselho Nacional de Meio Ambiente de 2006 e de 2013, estabeleceram procedimentos para o licenciamento ambiental em assentamentos de reforma agrária, e tinha por meta estancar o desmatamento nessas áreas. Com a publicação do Novíssimo Código Florestal (Lei no 12.651/2012) foi criado o Cadastro Ambiental Rural (CAS), representando mais um instrumento de controle do desmatamento, principalmente aqueles ocorridos nas áreas de assentamentos rurais. Por meio deste cadastro, os assentados deverão conseguir a regularização de áreas consolidadas até 22 de julho de 2008, data da promulgação do Decreto no 6.514, que trata das infrações e sanções administrativas ao meio ambiente e o procedimento para sua apuração.

Résumé :

Forest fires in Sumatra lead to a very extreme climate changes around the earth, so there would still be a difficult job for atmosphere researchers. This research was conducted to know the weather conditions by determining the condition of Water Vapor (WV) on the island of Sumatra. Monitoring the condition of WV can be done by using remote sensing techniques, by processing the image satellite data namely Terra Modis (Moderate Resolution Imaging Spectroradiometer). Data calculation condition WV, as one of the parameters of dynamic atmosphere. The data comes from Terra Modis satellite image, the data on Canal 2, 5, 17, 18 and 19 with a wavelength range; 0,865�m, 1.24 �m, 0.905 �m, 0.936 �m and 0,940 �m. From these results obtained from the average value of Water Vapor before and after fires in 2012. Water Vapor taken from TERRA MODIS satellite imagery (y) with a correction factor of 0.9865. Although the correlation (r) between Water Vapor from MODIS data is high, it can be seen that between Water Vapor in 2012 ranged between 3-8 cm. 82%, however only about 68% of Water Vapor MODIS diversity that can be presented by the equation model to approach the actual value of Water Vapor. With these data will greatly affect the weather cycle in Indonesia.

Résumé :

As construções em terra são soluções reconhecidas de baixo impacto ambiental. São construções duráveis, fortes, climaticamente eficientes, formalmente flexíveis e são compostas por recursos renováveis e reaproveitáveis favorecendo o desenvolvimento sustentável. Este artigo classifica as variações construtivas de aplicação da técnica de construção em terra superadobe. Também conhecido como “adobe ensacado”, “saco contínuo de terra estabilizada”, “earthbag building” ou “Earth-filled bags”, o superadobe consiste na técnica construtiva onde as paredes são construídas basicamente por sacos preenchidos com terra e areia empilhados, com arame farpado entre eles. A técnica foi desenvolvida como possível solução de construção na lua, depois foi aplicada pare resolver a problemática de habitação popular, atualmente é possível encontrar construções em superadobe robustas, com diferentes usos e com associações de outras técnicas construtivas. Este artigo tem por objetivo tabular as variações construtivas de aplicação da técnica de construção em terra superadobe já executadas, a fim de auxiliar pesquisas futuras no reconhecimento e superação dos limites e variações da técnica construtiva. O método é descritivo qualitativo, com investigação de cunho exploratório interdisciplinar, por meio de levantamento técnico em revistas especializadas em arquitetura, engenharia e sustentabilidade.Palavras-Chave: Superadobe, sustentabilidade, arquitetura, construção em terra.

Résumé :

Em Santa Bárbara D'Oeste,SP, foram realizados dois mapeamentos do uso da terra em área de 14.625 ha. No primeiro utilizou-se fotografias aéreas verticais pancromáticas (data de 25/6/78), na escala 1:35.000, e no segundo utilizou-se imagens orbitais do satélite LANDSAT-5 com sensor "Thematic Mapper" (data de 12/8/91), escala 1: 100.000, nas bandas 3, 4 e 5 e composição colorida 3/4/5. Para auxiliar a confecção desses mapas, obteve-se chaves de interpretação, tanto para as aerofotos como para as imagens orbitais. As fotografias aéreas proporcionaram um maior nível de detalhamento na identificação do uso da terra. A banda 3 e a composição colorida 3/4/5 foram as mais eficientes entre as imagens orbitais. Entre 1978 e 1991, a área de ocorrência de cana-de-açúcar permaneceu a mesma, as áreas de mata e pastagem diminuíram, enquanto que as áreas de reflorestamento e urbana aumentaram. Essa região teve sua capacidade de uso enquadrada, na maior parte, na classe IV: terras mais apropriadas para pastagens ou plantas perenes como a cana-de-açúcar, devendo-se aplicar técnicas intensivas de conservação, e com aptidão baseada em práticas agrícolas que refletem um alto nível tecnológico.

Résumé :

O processo de ocupação das terras do Cerrado brasileiro tem impactado severamente sua paisagem natural nas últimas décadas. No presente estudo estimou-se as mudanças no uso e cobertura da terra ocorridas entre 2000 e 2016 na região do MATOPIBA usando dados e técnicas de sensoriamento remoto. Estimou-se também as áreas de agricultura irrigada e as alterações no uso e cobertura da terra ocorridas dentro de áreas protegidas na região de estudo. Nove classes de uso e cobertura de terra (corpos de água, cerrado denso, cerrado aberto, floresta ciliar, agricultura, campos irrigados, sombra, campos queimados e solo exposto) foram detectadas usando imagens de satélite e a técnica de classificação da máxima verossimilhança. Com base nos resultados desta pesquisa, observou-se o aumento 40,9% de campos agrícolas e solos expostos entre 2000 e 2016 na área de estudo. As áreas de agricultura irrigada aumentaram aproximadamente 154% (102.000 hectares) no mesmo período. Embora os diferentes tipos de antropização de áreas naturais tenham sido observados em toda a área de estudo, o maior aumento ocorreu na porção sul, onde as terras mais aptas para agricultura mecanizada estão mais concentradas. A antropização também aumentou dentro das terras protegidas de uso sustentável, onde as atividades de conservação deveriam ser prioritariamente implementadas na região de estudo, tais como a criação de corredores ecológicos e políticas públicas, visando o uso sustentável de seus recursos naturais.Palavras-chave: desmatamento; Cerrado; sensoriamento remoto. LAND USE AND LAND COVER DYNAMIC IN THE MATOPIBA REGION BETWEEN 2000 AND 2016 ABSTRACT: The land occupation process in the Brazilian Cerrado has severely impacted its natural landscape in the last decades. In this study, we estimated the land use and land cover changes occurred in the MATOPIBA region between 2000 and 2016 by using remotely sensed data and techniques. We also estimated the irrigated fields and deforested lands occurred within protected areas in the study region. Nine land use and land cover classes (water bodies, dense cerrado, open cerrado, riparian forest, agriculture, irrigated fields, shade, burned fields, and exposed soil) were detected by using Landsat imagery and by applying the Maximum Likelihood remote sensing technique. Based on our study results, we observed an increase of 40,9% agricultural fields and exposed soils during between 2000 and 2016 in the study region. Irrigated fields increased approximately 154% (102,000 ha) during the studied period. Although different types of anthropization were observed throughout the study area, the major increasing change was observed within the southern portion, where the most suitable agricultural lands are concentrated. The anthropization also increased within protected lands of sustainable use, where conservation activities should be prioritarily enforced in the study region, such as the creation of ecological corridors and public policies aiming sustainable use of its natural resources.Keywords: deforestation; Cerrado; remote Sensing.

Résumé :

A quantitative assessment of the current state of natural fodder areas located in the Turano-Uyuk basin (Tuva) was made. Vegetation monitoring was carried out on the basis of Terra Modis satellite data by the following indicators: normalized vegetation index, gross primary production (GPP) and evapotranspiration. The productivity of plant associations was compared, their growth rate and the degree of GPP dependence on the sum of temperatures and evapotranspiration were determined. The results of ground-based studies performed by generally accepted methods were used for veriﬁ cation. Remote indicators of gross production for the growing season ranged from 33.3 t/ha for halophytic meadows, and up to 48.8 t/ ha for wetland habitats. Depending on the species composition, gross productivity of glycophytic meadows during the growing season was 39.9– 48.7 t/ ha. A comparison of the data showed signiﬁ cant differences in the remote and actual productivity of fodder areas, which can be leveled by means of correlation with the ground-based indicators. The best results of the relationship between gross primary production and the vegetation index with the sum of positive temperatures were identiﬁ ed by polynomial equations of the third degree. The maximum period of phytomass development of natural fodder areas (meadow communities) was recorded before the beginning of June. Biological and environmental differences in the growth of vegetation during the season were noted in the period from 10-11 June to 19-20 July. The decrease in the accumulation of gross primary production by mid-July and the end of September was caused by weather conditions. The optimal grazing periods in the meadows in the Turano-Uyuk basin were determined.

Résumé :

A ocupação do Imbé efetivada em 3 de abril de 1963 acabou inesperadamente se tornando um marco na luta pela terra. Ela foi uma das primeiras ações de ocupação de terras, pois na data referida um grupo de lavradores ocupou a localidade chamada Segundo Norte do Imbé, no município de Campos. Uma das principais fontes para o estudo de tal ocupação, além dos jornais de época e relatórios policiais, foi o conjunto de memórias do militante comunista José Pureza, que teve participação destacada nesse evento. Seus relatos são certamente uma excelente fonte de informações, porém, como todo relato, ele contem lacunas e imprecisões, o que exige a sua confrontação com outros relatos, versões e memórias. O exame de outras memórisa sobre os fatos relativos ao Imbé é o tema principal desse artigo.

Résumé :

The Terra satellite has been operating in orbit for 20 years. The Terra satellite is also called the flagship earth-observing satellite. The two Clouds and the Earth’s Radiant Energy System CERES instruments on board continue to function nominally. Their expected mission lifetime was 7 years. Critical to their performance is the longevity of the scanning gimbals. This can be traced to the performance of the fluid-lubricated bearings. Two metrics are used to estimate their lifetime and health. Both lend themselves to readily available data and ease of interpretation. One is predicting the evaporative lubricant loss. This analysis indicates that the lubricant supply is adequate for the continual life of the gimbals. The second is trending the torque with time. Torque precursors are sampled quarterly. These data are converted to torque. Two types of torque behavior were examined. Contrasting torque data have supported the conclusion that the gimbals are operating nominally. This can be partially attributed to the design choices for the bearings and lubricant. The aim of this paper is to quantitatively describe the present health and expected life of the CERES gimbals on the Terra satellite.

Résumé :

Indonesia sebagai negara kepulauan, 2/3 dari luas wilayah Indonesia merupakan wilayah perairan atau lautan. Lautan menjadi salah satu sumber kehidupan bagi masyarakat Indonesia, termasuk yang ada di wilayah kabupaten Malang. Potensi hasil laut di kabupaten Malang selain ikan, ada juga cumi-cumi, rajungan, kerang-kerangan dan lain-lain. Kebaradaan ikan tidak dapat dipisahkan dari ekosistem laut terutama adanya produsen makanan yang terdapat di laut, yakni klorofil-a pada fitoplankton. Informasi yang digunakan untuk mendapatkan persebaran nilai konsentrasi klorofil-a dapat diperoleh dari hasil pengolahan data citra satelit Terra MODIS dan citra satelit Envisat Meris; yang diperkuat dengan data In Situ berupa pengambilan sampel air laut yang diuji di laboratorium. Proses pengolahan citra menggunakan citra Terra MODIS. Dari penelitian ini, diperoleh peta persebaran konsentrasi klorofil-a di perairan pantai Malang yang dihasilkan dari pengolahan citra Satelit dan analisa beberapa in Situ, berdasakan parameter konsentrasi klorofil-a. Hasil ini dapat disimpulkan bahwa Terra MODIS memiliki korelasi yang cukup kuat terhadap data in situ. Sedangkan uji korelasi antara data In Situ dengan citra Envisat Meris cukup lemah.

Résumé :

Telomeric Repeat-containing RNA (TERRA) are long non-coding RNAs transcribed from telomeric DNA sequences from multiple chromosome ends. Major research efforts have been made to understand TERRA roles and functions in several physiological and pathological processes. We summarize herein available data regarding TERRA’s roles in human cells and we report the first investigation in cutaneous T-cells lymphomas (CTCL) using real-time PCR. Among the TERRA analysed, our data suggest a particular role for TERRA 16p downregulation and TERRA 11q upregulation in CTCL lymphomagenesis.

A população mundial vem sofrendo, cada vez mais, as conseqüências das agressões efetuadas pelo homem ao meio ambiente, principalmente quanto à ocupação e uso inadequado das terras, o que ocasiona empobrecimento e depauperamento do solo, influenciando na qualidade e disponibilidade de água, levando à destruição das reservas florestais. Assim, é necessária a implantação de políticas públicas, que contemplem o desenvolvimento econômico, urbano, rural e social de uma região, preservando os recursos naturais para futuras gerações. A bacia em estudo está localizada entre as coordenadas UTM 764942; 7546214 e 741816; 7534759, com uma área de 14699,7ha. Este trabalho visou definir as classes de capacidade de uso de terra da microbacia do Ribeirão Pouso Alegre - Jaú (SP) através do Sistema de Informações Geográficas - SPRING. A carta de capacidade de uso da terra foi elaborada a partir do cruzamento das cartas clinográfica e de solo, que foram elaboradas pelo SIG Spring, e o cruzamento de dados foi feito através do LEGAL - Linguagem Espacial para Geoprocessamento Algébrico. Os resultados mostraram que a microbacia é constituída essencialmente pelas classes II e III e o SIG-SPRING permitiu através dos seus módulos discriminarem e quantificar as áreas das classes de terras, declive e capacidade de uso da terra rapidamente.

L., SIG-SPRING APPLIED IN DETERMINATION OF THE SOIL USE CAPACITY FOR POUSO ALEGRE WATERCSHED – JAÚ (SP) 2 SUMMARY The world population is increasingly suffering the consequences of attacks made by mankind to the environment, especially regarding the occupation and misuse of the land, which leads to soil impoverishment and depletion, affecting the water quality and its availability leading to forest reserve destruction. Therefore, there is a need to implement public policies that address economic, urban, rural, and social development of a region while preserving its natural resources for future generations. The watershed observed in this study is located between UTM coordinates 764,942 – 741,816 and 7,546,214 – 7,534,759 with an area of 14699.7ha. This study aimed to define soil use capacity classes of Pouso Alegre Watershed – Jaú (SP) using Geographic Information System – SPRING. The ability chart to soil use was developed from crossing the declivity and soil charts, which were drawn up by GIS – SPRING and the data linking was done by LEGAL – Space for Geo-processing Algebraic Language. The results showed that the watershed is mainly composed by classes II and III and GIS-SPRING allowed through its modules discriminating and quantifying the land classes area, slope, and capability to use it quickly.

Résumé :

AbstractIn this study of ship tracks, Moderate Resolution Imaging Spectroradiometer (MODIS) measurements from late-morning (Terra) and early-afternoon (Aqua) Earth Observing System platforms are analyzed in five separate geographically distributed cases to compare estimates of the sizes (and their changes in time) of droplets associated with ship exhaust. Ship tracks are readily detected in near-infrared imagery as bright features, especially in 2.13-μm observations. The Terra “MOD06” and Aqua “MYD06” cloud products are used to determine the effective radius of the ship-track droplets; droplet age (time in the atmosphere) is estimated as a function of the distance from the ship. Terra and Aqua MODIS estimates of droplet sizes in ship-track plumes are found to be in agreement, with a correlation greater than 0.90; for the cases studied, droplet sizes in the ship plumes are between 6 and 18 μm. Moreover, the droplets’ size growth rates inferred from the length of the ship track were found to average between 0.5 and 1.0 μm h−1.

Résumé :

ABSTRACTSea surface temperature (SPL) information is the most important water quality parameter in the ocean, especially in coastal areas. Remote sensing technology with Terra Modis satellite data is used for periodic monitoring of SPL changes. The purpose of this study was to analyze the temporal distribution of SPL on the coast of Malang, East Java. The data used are SPL data from Terra-MODIS satellite sensors in May 2018, 2019 and 2020. Analysis of the data used is descriptive analysis which includes temporal analysis of SPL based on SPL fluctuations in graphical form. The results showed that the temporal variation of the 2018-2020 SPL on the coast of Malang tends to increase. The SPL value in 2018 varies between 25 ° C - 26 ° C while in 2019 it varies between 26 ° C - 27 ° C and in 2020 it ranges between 30 ° C - 31 ° C. The highest average SPL value from 2018 - 2020 is in 2020 with a temperature of 30.58 ° C. In an effort to model sea surface temperatures used calculations using mathematical models. From the results obtained it can be concluded that the most optimal mathematical model is derived from the wavelength of 667 nm on May 23, 2020 with the equation model y = -0,498ln (x) + 27,936 which results in a correlation value of R = 0.6561.Keywords: sea surface temperature, terra modis, satellite, mathematical models.ABSTRAKInformasi suhu permukaan laut (SPL) merupakan parameter kualitas perairan yang paling penting di lautan terutama kawasan pesisir.

Résumé :

The Clouds and the Earth’s Radiant Energy System (CERES) Energy Balanced and Filled (EBAF) top-of-atmosphere (TOA), Edition 4.0 (Ed4.0), data product is described. EBAF Ed4.0 is an update to EBAF Ed2.8, incorporating all of the Ed4.0 suite of CERES data product algorithm improvements and consistent input datasets throughout the record. A one-time adjustment to shortwave (SW) and longwave (LW) TOA fluxes is made to ensure that global mean net TOA flux for July 2005–June 2015 is consistent with the in situ value of 0.71 W m−2. While global mean all-sky TOA flux differences between Ed4.0 and Ed2.8 are within 0.5 W m−2, appreciable SW regional differences occur over marine stratocumulus and snow/sea ice regions. Marked regional differences in SW clear-sky TOA flux occur in polar regions and dust areas over ocean. Clear-sky LW TOA fluxes in EBAF Ed4.0 exceed Ed2.8 in regions of persistent high cloud cover. Owing to substantial differences in global mean clear-sky TOA fluxes, the net cloud radiative effect in EBAF Ed4.0 is −18 W m−2 compared to −21 W m−2 in EBAF Ed2.8. The overall uncertainty in 1° × 1° latitude–longitude regional monthly all-sky TOA flux is estimated to be 3 W m−2 [one standard deviation (1 σ)] for the Terra-only period and 2.5 W m−2 for the Terra– Aqua period both for SW and LW fluxes. The SW clear-sky regional monthly flux uncertainty is estimated to be 6 W m−2 for the Terra-only period and 5 W m−2 for the Terra– Aqua period. The LW clear-sky regional monthly flux uncertainty is 5 W m−2 for Terra only and 4.5 W m−2 for Terra– Aqua.

Résumé :

Although long noncoding RNAs (lncRNAs) are emerging as new modulators in the fate decision of pluripotent stem cells, the functions of specific lncRNAs remain unclear. Here, we found that telomeric RNA (TERRA or TelRNA), one type of lncRNAs, is highly expressed in mouse embryonic stem cells (mESCs) but declines significantly upon differentiation. TERRA is induced by the Wnt/β-catenin signaling pathway and can reproduce its self-renewal-promoting effect when overexpressed. Further studies revealed that T cell factor 3 ( TCF3) is a potential downstream target of TERRA and mediates the effect of TERRA in mESC maintenance. TERRA inhibits TCF3 transcription, while enforced TCF3 expression abrogates the undifferentiated state of mESCs supported by TERRA. Accordingly, the transcripts of the pluripotency genes Esrrb, Tfcp2l1, and Klf2, repressed by TCF3 in mESCs, are increased in TERRA-overexpressing cells. Our study therefore highlights the important role of TERRA in mESC maintenance and also uncovers a mechanism by which TERRA promotes self-renewal. These data will expand our understanding of the pluripotent regulatory network of ESCs.

Résumé :

Este artigo pretende demonstrar a inconstitucionalidade da tese do marco temporal da ocupação, que fixou a efetiva ocupação física dos indígenas na data da promulgação da Constituição Federal de 1988 como referencial para se reconhecer os direitos sobre as terras tradicionalmente ocupadas. Cada procedimento demarcatório deve obedecer ao Decreto-Lei nº 1.775, de 08 de janeiro de 1996, exige um aprofundado estudo antropológico e deve considerar as características históricas e sociológicas próprias da área impactada. Resta demonstrado que esse instituto jurídico vai de encontro com preceitos fundamentais previstos na CF/1988 e com pactos e declarações internacionais de Direitos Humanos pelas quais o país se obrigou a respeitar, inviabilizando o pleno exercício do direito originário sobre a terra por parte dos indígenas brasileiros. Ademais, nega um passado de articulações dos movimentos indígenas junto à Assembleia Constituinte de 1987 para a positivação de direitos, perpetua a impunidade dos violadores de tais direitos, e, ainda, acirra os conflitos territoriais.

Résumé :

Some studies have shown that the estimation of global sunshine duration can be done with the help of geostationary satellites because they can record several images of the same location in a day. In this paper, images obtained from the MODIS (Moderate Resolution Imaging Spectroradiometer) sensors of polar orbiting satellites Aqua and Terra were used to estimate daily global sunshine duration for any region in Turkey. A new quadratic correlation between daily mean cloud cover index and relative sunshine duration was also introduced and compared with the linear correlation. Results have shown that polar orbiting satellites can be used for the estimation of sunshine duration. The quadratic model introduced here works better than the linear model especially for the winter months in which very low sunshine duration values were recorded at the ground stations for many days.

Abstract. Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue (DB) collection 5.1 (c5.1) aerosol optical depth (AOD) data were analyzed and evaluated for the first time from an independent research group using eight years of Terra (2000–2007) and Aqua (2002–2009). Uncertainties in the DB AOD were identified and studied, and our results show that the performance of DB c5.1 is strongly dependent on surface albedo and aerosol microphysics. Using data with only "very good" quality assurance, the root-mean-square error (RMSE) of the DB Terra (Aqua) AOD is 0.24 (0.19) when validated against AERONET. Expanding upon the uncertainty analysis, the potential of applying the DB products for aerosol assimilation was explored. Empirical corrections and quality assurance procedures were developed for North Africa and the Arabian Peninsula to create a data assimilation (DA)-quality DB product. After applying those procedures, the RMSE is reduced by 18.1% (18.2%) for Terra (Aqua) DB data. Prognostic error models of 0.069 + 0.175 × AODTerra_DB with no noise floor and 0.048 + 0.182 × AODAqua_DB with a noise floor of 0.104 were found for DA-quality Terra and Aqua DB data, respectively. These procedures were also applied to two months of DB collection 6 (c6) AOD data, and reductions in RMSE were found, indicating that the algorithms developed for c5.1 data are applicable to c6 data to some extent.

O mapa de capacidade de uso da terra do município foi elaborado a partir dos mapas de classes de declive e de solo, tomando-se por base as características de cada um e utilizando-se da tabela de julgamento de classes de capacidade de uso. As áreas da classe e subclasses de capacidade de uso das terras determinadas pelo SIG –IDRISI foram: IIe,s (22,64%); IIIe (8,62%); IIIe,s (15,83%); IIIs (29,97%); IVe (10,82%); VIe (3,95%) e VIIe (0,96%). Os resultados permitiram inferir que as subclasses mais significativas foram a IIIs e IIe,s. As classes de declive de 0 a 20% ocorrem em mais de ¾ do Município, sendo as áreas planas, as mais representativas, pois ocorrem em quase 1/3 da área total. O SIG mostrou-se uma excelente ferramenta para determinação da capacidade de uso da terra, demonstrando que a utilização do geoprocessamento facilita e agiliza o cruzamento dos dados digitais, permitindo seu armazenamento, que poderão ser utilizados para outras análises em futuros planejamentos geoambientais.

LAND USE CAPABILITY DETERMINATION OF SÃO MANUEL MUNICIPALITY-SP 2 ABSTRACT The present work purposed a land use capability chart development from São Manuel Municipality-SP using a Geographical Information System - Idrisi aiming to contribute for a better territorial organization and soil occupation planning. The basin is located in the 22º 28’ 20” geographical co-ordinates at 22º 53’ 10” S latitude, 48º 21’ 52” and 48º 48’ 00” meridian of W Gr. longitude, presenting an area of 9180,12ha. The chart of the basin land use capability was elaborated from the soil and sloping class charts based on each one characteristics and using the class table of use capability. The class and subclass areas determined through the Geographical Information System IDRISI presented the following values: IIe,s (22,64%), IIIe (8,62%), IIIe,s (15,83%), IIIs (29,97%), IVe (10,82%), VIe (3,95%) and VIIe (0,96%). The results allowed to infer that the most significant sub classes were IIIs and IIe,s. The 0 to 20% sloping classes have occurred in more than ¾ of the district. Plane areas were the most significant since they occur in nearly 1/3 of the whole area. The Geographical Information System IDRISI has been an excellent tool to determine land use capability, specially related with geo-processing use. The later also facilitates the input, analysis and display of spatial environmental information as well as data digital storage which could be used for other analyses in further geo-environmental design.

Résumé :

High-resolution soil moisture (SM) information is essential for regional to global hydrological and agricultural applications. The Soil Moisture Active Passive (SMAP) offers daily global composites of SM at coarse-resolution 9 and 36 km, with data gaps limiting its local application to depict SM distribution in detail. To overcome the aforementioned problem, a downscaling and gap-filling novel approach was adopted, using random forest (RF) and artificial neural network (ANN) algorithms to downscale SMAP SM data, using land-surface variables from moderate-resolution imaging spectroradiometer (MODIS) onboard Aqua and Terra satellites from the years 2018 to 2019. Firstly, four combinations (RF+Aqua, RF+Terra, ANN+Aqua, and ANN+Terra) were developed. Each combination downscaled SMAP SM at a high resolution (1 km). These combinations were evaluated by using error matrices and in situ SM at different scales in the ShanDian River (SDR) Basin. The combination RF+Terra showed a better performance, with a low averaged unbiased root mean square error (ubRMSE) of 0.034 m3/m3 and high averaged correlation (R) of 0.54 against the small-, medium-, and large-scale in situ SM. Secondly, the impact of various land covers was examined by using downscaled SMAP and in situ SM. Vegetation attenuation makes woodland more error-prone and less correlated than grassland and farmland. Finally, the RF+Terra and ANN+Terra combinations were selected for their higher accuracy in gap filling of downscaled SMAP SM. The gap-filled downscaled SMAP SM results were compared spatially with China Land Data Assimilation System (CLDAS) SM and in situ SM. The RF+Terra combination outcomes were more humid than ANN+Terra combination results in the SDR basin. Overall, the RF+Terra combination gap-filled data showed high R (0.40) and less ubRMSE (0.064 m3/m3) against in situ SM, which was close to CLDAS SM. This study showed that the proposed RF- and ANN-based downscaling methods have a potential to improve the spatial resolution and gap-filling of SMAP SM at a high resolution (1 km).

Résumé :

RNA-protein interactions drive key cellular pathways such as protein translation, nuclear organization and genome stability maintenance. The human telomeric protein TRF2 binds to the long noncoding RNA TERRA through independent domains, including its N-terminal B domain. We previously demonstrated that TRF2 B domain binding to TERRA supports invasion of TERRA into telomeric double stranded DNA, leading to the formation of telomeric RNA:DNA hybrids. The other telomeric protein TRF1, which also binds to TERRA, suppresses this TRF2-associated activity by preventing TERRA-B domain interactions. Herein, we show that the binding of both TRF1 and TRF2 to TERRA depends on the ability of the latter to form G-quadruplex structures. Moreover, a cluster of arginines within the B domain is largely responsible for its binding to TERRA. On the other side, a patch of glutamates within the N-terminal A domain of TRF1 mainly accounts for the inhibition of TERRA-B domain complex formation. Finally, mouse TRF2 B domain binds to TERRA, similarly to its human counterpart, while mouse TRF1 A domain lacks the inhibitory activity. Our data shed further light on the complex crosstalk between telomeric proteins and RNAs and suggest a lack of functional conservation in mouse.

Linear contrail coverage, optical property, and radiative forcing data over the Northern Hemisphere (NH) are derived from a year (2012) of Terra and Aqua Moderate-resolution Imaging Spectroradiometer (MODIS) imagery and compared with previously published 2006 results (Duda et al., 2013; Bedka et al., 2013; Spangenberg et al., 2013) using a consistent retrieval methodology. Differences in the observed Terra-minus-Aqua screened contrail coverage and patterns in the 2012 annual-mean air traffic estimated with respect to satellite overpass time suggest that most contrails detected by the contrail detection algorithm (CDA) form approximately 2 h before overpass time. The 2012 screened NH contrail coverage (Mask B) shows a relative 3 % increase compared to 2006 data for Terra and increases by almost 7 % for Aqua, although the differences are not expected to be statistically significant. A new post-processing algorithm added to the contrail mask processing estimated that the total contrail cirrus coverage visible in the MODIS imagery may be 3 to 4 times larger than the linear contrail coverage detected by the CDA. This estimate is similar in magnitude to the spreading factor estimated by Minnis et al. (2013). Contrail property retrievals of the 2012 data indicate that both contrail optical depth and contrail effective diameter decreased approximately 10 % between 2006 and 2012. The decreases may be attributed to better background cloudiness characterization, changes in the waypoint screening, or changes in contrail temperature. The total mean contrail radiative forcings (TCRFs) for all 2012 Terra observations were −6.3, 14.3, and 8.0 mW m−2 for the shortwave (SWCRF), longwave (LWCRF), and net forcings, respectively. These values are approximately 20 % less than the corresponding 2006 Terra estimates. The decline in TCRF results from the decrease in normalized CRF, partially offset by the 3 % increase in overall contrail coverage in 2012. The TCRFs for 2012 Aqua are similar, −6.4, 15.5, and 9.0 mW m−2 for shortwave, longwave, and net radiative forcing. The strong correlation between the relative changes in both total SWCRF and LWCRF between 2006 and 2012 and the corresponding relative changes in screened contrail coverage over each air traffic region suggests that regional changes in TCRF from year to year are dominated by year-to-year changes in contrail coverage over each area.
