The lagoa Salgada is situated on the north coast of the State of Rio de Janeiro, between the districts of Campos dos Goytacazes and São João da Barra, at 41º00'30'' W and 21º54'10''S. In the margins of the lagoon the presence of recent stromatolitic constructions was verified. The stromatolite may be defined as lithified biosedimentary structure, growing through the increase of sediment blade trapping by the carbonate precipitation as result of microbian organism activity. The objective of this study was to describe and to determine the internal morphology of domal type stromatolite of the lagoa Salgada. Through cutting, three different stages were observed: the first (base) is present as a thrombolitic stage with spread blade; the second (intermediary) is a thrombolitic-stromatolitic stage with spread and continuous blade; the third (top) is stromatolitic and the most recent stage of the structure, presenting continuous blade and with interruptions rare. Besides the presence of cyanobacteria and mollusk shells, were observed also internee palinomorphs inside the domal stromatolite. It was possible to observe that filament cyanobacteria contributed to the formation of blade of domal stromatolite and the microgastropod contributed for the destruction of the blade.

Lagoa Salgada is situated in the north coast of State of Rio de Janeiro, between the districts of Campos dos Goitacazes and São João da Barra, some 41º00'30" W and 21º54'10"S. In the margins of the lagoon the presence of recent stromatolitic constructions was verified. The stromatolite may be defined as lithifying biosedimentary structure, growing through of sediment blade trapping by the carbonate precipitation as result of microbian organism activity. The aim of this study was to characterize the cyanobacteria assemblage in stratiform stromatolites found on the floor of lagoa Salgada. Within the stratiform stromatolites 21 species of cyanobacteria were found, Microcoleus chthonoplastes (Thuret) Gomont 1892 and Lyngbya aestuarii (Liebman) Gomont 1892 are frequent in these stromatolites. The presence of calcite was observed in the stratiform stromatolites. The filamentous cyanobacteria are responsible for the union and imprisonment of sediment to form the layers in the stromatolites. The skeleton remains of mollusks, foraminifers and ostracod found in the area, work as a source of calcium carbonate and of sediment to structure the stromatolites

Communication airports in Poland after 1918 The history of communication airports coincides with the century-long existence of the reborn Polish State, because it was only after 1918 that the first airports adapted to passenger traffic were established in the country. Two periods of their development deserve particular attention: the interwar period, in which the communication aviation was born, and the time after 2004, when its rapid expansion was noted. The establishment and development of the communication aviation of the Second Polish Republic was strongly associated with the statist policy aimed at modernizing the state. This is evidenced by the construction of airports in Warsaw, Gdynia, Katowice, Łódź and Vilnius, whose activities have helped to integrate the country after the years of partitions. In People’s Poland, civilian communication was based on a network of military airports, which was supplemented with a new airport in Gdańsk-Rębiechów. Large areas of the north-eastern voivodeships were excluded from air connections and timid attempts to overcome these disproportions only appeared in the Third Republic of Poland in the form of airports in Lublin and Radom. The fourfold increase in the number of passengers served by Polish airports in 2004–2016 was an unquestionable phenomenon influenced by the Open Sky policy.

The article has three goals. The first is to present the history of research on Polish dialectal phrasematics. In particular, attention was paid to the last five years, i.e. the period 2015–2020. The works in question were ordered according to the dialectological key, taking into account the following dialects: Greater Polish, Masovian, Silesian, Lesser Polish, and the North and South-Eastern dialects. The second goal is to indicate the methodologies that have so far been used to describe dialectal phrasematics. Initially, component analysis was used, which was part of the structuralist research trend, later (more or less from the late 1980s) the ethnolinguistic approach, especially the description of the linguistic picture of the world, began to dominate. The third goal of the article is to provide perspectives. The author once again (as he did it in his earlier works) postulates the preparation of a dictionary of Polish dialectal phrasematics.

Slip is a semifluid clayey type of material used in the ceramic industry for coating earthware products, such as bricks and tiles, thus providing distinct surface colors or patterns. In the present work a characterization was conducted to identify the mineralogical as well the chemical and physical properties of geological materials existing in the slip used by industries in the north region of the state of Rio de Janeiro, Brazil. The basic natural materials composing a slip, namely clay and kaolin, are responsible for changes not only the slip plasticity but also in its viscosity and adhesion to the surface of the ceramic piece. The slip characterization was performed in terms of particle size analysis, Atterberg limits and actual grain density. The chemical composition was obtained by X-ray fluorescence and the thermal properties by differential thermal analysis. The results indicated that marked differences exist between slip from distinct origins. A few slip samples failed to present the required properties.

This study evaluated the space-time variability of fire foci via environmental satellites for the State of Rio de Janeiro (SRJ) based on statistical procedures. The fire foci in the period of 2000 to 2015 were obtained from the BDQueimadas fire database. Descriptive, exploratory, and multivariate statistical analyses were performed in the software environment R i386 version 3.2.5. The north region had 6760 foci (21.11%), the south-central region had 3020 foci (9.43%), the Middle Paraíba had 6,352 foci (19.84%), the Metropolitan areas had 6671 foci (20.83%), and the Green Coast region had 292 foci (0.91%). The cluster analysis identified three homogeneous groups of fire foci (G1, G2, and G3) but did not include the municipality of Campos dos Goytacazes (NA). The G1 group (6.21 ± 0.01 foci, 57.61%) included areas throughout the state and covered the coastal region and lowlands towards the north. The G2 group (6.21 ± 0.01 foci, 34.81%) included the northern, south-central, and coastal shallows regions. The G3 group (6.21 ± 0.01 foci, 9.78%) included the mountain ranges of the state. Environmental characteristics and socioeconomic are crucial in the dynamics of fire foci in Rio de Janeiro.

Brazil began to explore its seas in the 60’s of the XX Century looking for petroleum. This journey began in the Northeast and the first oil field produced offshore was the Guaricema Field, in the State of Sergipe. During the 70’s, Petrobrás found oil in the Campos Basin, between the States of Espírito Santo and Rio de Janeiro, that became the most important oil province in Brazil until the discovery of the Pre-Salt province, in the Santos Basin. As these fields are producing for a long time, many of them are already completely depleted or their production is in way of to be not commercial anymore, and their facilities need to be decommissioned. This review of decommissioning practices of fixed offshore platforms carried out worldwide has focus on the removal of topside with special vessels designed for this purpose or with conventional methods (crane vessels + barge). It will show the benefits of using specialised heavy lift vessels to remove the topsides and move it to shore for dismantling / recycling / reuse / disposal. The cases for study were the successful decommissioning projects in the North Sea: Brent B/D, Valhall QP, Viking, Curlew, Eider A, Golden Eye and Leman, Iwaki-Oki, Halfweg Q1, Yme and Ninian North.
