Crary Mountains
Crary Mountains (76°48′S 117°40′W) are a group of ice-covered volcanoes in Marie Byrd Land, Antarctica. They consist of two or three shield volcanoes, named Mount Rees, Mount Steere and Mount Frakes, which developed during the course of the Miocene and Pliocene and last erupted about 30,000-40,000 years ago. The first two volcanoes are both heavily incised by cirques, while Mount Frakes is better preserved and has a 4 kilometres (2.5 mi) wide caldera at its summit. Boyd Ridge is another part of the mountain range and lies southeast of Mount Frakes; it might be the emergent part of a platform that underlies the mountain range. The volcanoes consist mainly of basalt, trachyte and phonolite in the form of lava flows, scoria and hydrovolcanic formations. Volcanic activity here is linked to the West Antarctic Rift system, which is responsible for the formation of a number of volcanoes in the region. During their existence, the range was affected by glaciation and glacial-volcanic interactions.

Milas
Milas (Ancient Greek:, Mylasa) is an ancient city and the seat of the district of the same name in Muğla Province in southwestern Turkey. The city commands a region with an active economy and very rich in history and ancient remains, the territory of Milas containing a remarkable twenty-seven archaeological sites of note. The city was the first capital of ancient Caria and of the Anatolian beylik of Menteşe in mediaeval times. The nearby Mausoleum of Hecatomnus is classified as a UNESCO World Heritage Site. Milas is focused on agricultural and aquacultural processing, related industrial activities, services, transportation (particularly since the opening of Milas-Bodrum Airport), tourism and culture. The centre lies about 20 km from the coast and is closer to the airport than Bodrum itself, with many late arrival passengers of the high season increasingly opting to stay in Milas rather than in Bodrum where accommodation is likely to be difficult to find. Milas district covers a total area of 2167 km2 and this area follows a total coastline length of 150 km, both to the north-west in the Gulf of Güllük and to the south along the Gulf of Gökova, and to these should be added the shores of Lake Bafa in the north divided between the district area of Milas and that of Aydın district of Söke. Along with the province seat of Muğla and the province's southernmost district of Fethiye, Milas is among the prominent settlements of south-west Turkey, these three centers being on a par with each other in terms of all-year population and the area their depending districts cover. Five townships have their own municipalities, and a total of 114 villages depend on Milas, distinguishing the district with a record number of dependent settlements for a very wide surrounding region. Milas center is situated on a fertile plain at the foot of Mount Sodra, on and around which sizable quarries of white marble are found and have been used since very ancient times.

ISPRS International Journal of Geo-Information
The International Society for Photogrammetry and Remote Sensing (ISPRS) is an international non-governmental organization that enhances international cooperation between the worldwide organizations with interests in the photogrammetry, remote sensing and spatial information sciences. Originally named International Society for Photogrammetry (ISP), it was established in 1910, and is the oldest international umbrella organization in its field, which may be summarized as addressing “information from imagery”. ISPRS achieves its aims by: The ISPRS' scientific and technical programs are organized by five technical commissions. Each commission is sponsored by an ISPRS member organization for the four-year period between congresses. The five technical commissions have established around 60 working groups which are responsible for particular topics within the commissions’ areas of interest. All technical commissions hold a symposium within their country in 2018. Smaller workshops will be organized by the working groups before the 2020 congress from June 28 - July 4, 2020, in Nice, France, by the French Society for Photogrammetry and Remote Sensing.

Sediment Quality Triad (SQT)
In aquatic toxicology, the sediment quality triad (SQT) approach has been used as an assessment tool to evaluate the extent of sediment degradation resulting from contaminants released due to human activity present in aquatic environments (Chapman, 1990). This evaluation focuses on three main components: 1.) sediment chemistry, 2.) sediment toxicity tests using aquatic organisms, and 3.) the field effects on the benthic organisms (Chapman, 1990). Often used in risk assessment, the combination of three lines of evidence can lead to a comprehensive understanding of the possible effects to the aquatic community (Chapman, 1997). Although the SQT approach does not provide a cause-and-effect relationship linking concentrations of individual chemicals to adverse biological effects, it does provide an assessment of sediment quality commonly used to explain sediment characteristics quantitatively. The information provided by each portion of the SQT is unique and complementary, and the combination of these portions is necessary because no single characteristic provides comprehensive information regarding a specific site (Chapman, 1997)

Group on Earth Observations
The Group on Earth Observations (or GEO) coordinates international efforts to build a Global Earth Observation System of Systems (GEOSS). It links existing and planned Earth observation systems and supports the development of new ones in cases of perceived gaps in the supply of environment-related information. It aims to construct a global public infrastructure for Earth observations consisting in a flexible and distributed network of systems and content providers.

McClintock Arctic Expedition
The McClintock Arctic Expedition of 1857 was a British effort to locate the last remains of the lost Franklin Arctic Expedition. Led by captain Francis Leopold McClintock aboard the steam yacht Fox, the expedition spent two years in the region and ultimately returned with the only written message from the doomed expedition. McClintock and crew were awarded the Arctic medal in recognition of their achievements.

Mobile Local Search
Mobile local search is a technology that lets people search for local things using mobile equipment such as mobile phones, PDAs, and other mobile devices. Mobile local search satisfies the need to offer a mobile subscriber spontaneous access to near-position services and information such as businesses, products, events, restaurant, movie theatre or other local information. Mobile local search is the search and discovery of persons, places, and things within an identifiable space defined by distinct parameters. These parameters are evolving. Today they include social networks, individuals, cities, neighborhoods, landmarks, and actions that are relevant to the searcher's past, current, and future location. These parameters provide structure to vertically deep and horizontally broad data categories that can stand-alone or are combined to comprise searchable directories. Mobile local search is usually based on organized directories accessed through specialized search tools, rather than the web, although mobile local search often provides links to mobile (WAP) web sites. It is also an application of a location-based service.

Impact of Particles on Pulmonary Endothelial Cells
Due to particle sizes ranging from the nanometre to the millimetre scale, these particles can be easily inhaled or absorbed by the skin, reaching the cells of the pulmonary alveoli and finally entering the bloodstream, which can lead to health adverse effects. Endothelial cells (ECs) guarantee permeability for the passage of blood, hormone fluids, macromolecules and platelets through arteries, veins, arterioles and venules and controls blood flow and vascular relaxation and constriction. The function of pulmonary endothelial cells (PECs) is not very different from vascular endothelial cells; they regulate blood flow but also control the passage of liquid and macromolecules between the interstitial space, the vessels and the smooth muscle cells.

Geomatic Sensors for Heritage Documentation
Geomatic technologies have been widely populated for cultural heritage applications, while the scientific field is quite broad: from underwater to close-range to low-altitude and satellite observations. Geomatic sensors have been used in applications such as close-range approaches with red-green-blue (RGB) cameras and Terrestrial Laser Scanners (TLS), as well as underwater studies. Low-altitude sensors on Unmanned Aerial Vehicles (UAVs) have also been widely used with RGB and multispectral cameras, as well as lidar and thermal sensors.
