Hot Container Composting
Hot container composting (also referred to as in-vessel composting for larger industrial batches) is different to cold composting, in that compost is created without losing valuable heat. Heat loss is the reason why a compost pile takes so long to decompose. Observers have noted that the time taken to create compost can be dramatically reduced by retaining the heat in a suitably insulated container. Another observation noted is the way the compostable items are added and mixed which allows for aeration. This is an important step in the process. Compost becomes anaerobic due to the absence of air, and this can result in it becoming smelly. By adding large, medium and fine items to the top of the container, space is provided in between the items for the air to flow from bottom to top. This creates a trickle ventilation. Compost made with this method is called aerobic composting.

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.

Coastal Assessment and MAM of Sea Level Rise
Sea level rise (SLR) is one of the most pressing challenges of climate change and has drawn noticeable research interest. Factors induced by global climate change, such as temperature increase, have resulted in both direct and indirect changes in sea levels at different spatial scales. Various climatic and non-climatic events contribute to sea level changes, posing risks to coastal and low-lying areas. Nevertheless, changes in sea level are not uniformly distributed globally due to several regional factors such as wave actions, storm surge frequencies, and tectonic land movement. The high exposure to those factors increases the vulnerability of subjected areas to SLR impacts. The impacts of events induced by climate change and SLR are reflected in biophysical, socioeconomic, and environmental aspects. Different indicator-based and model-based approaches are used to assess coastal areas’ vulnerabilities, response to impacts, and implementation of adaptation and mitigation measures. Various studies have been conducted to project future SLR impacts and evaluate implemented protection and adaptation approaches, aiding policymakers in planning effective adaptation and mitigation measures to reduce damage.

Hurricane Preparedness
Cyclone mitigation encompasses the actions and planning taken before a tropical cyclone strikes to mitigate damage and injury from the storm. Knowledge of tropical cyclone impacts on an area help plan for future possibilities. Preparedness may involve preparations made by individuals as well as centralized efforts by governments or other organizations. Tracking storms during the tropical cyclone season helps individuals know current threats. Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers provide current information and forecasts to help individuals make the best decision possible.

Soufrière Hills Volcano
User:RMCD bot/subject notice The Soufrière Hills volcano is an active, complex stratovolcano with many lava domes forming its summit on the Caribbean island of Montserrat. Many volcanoes in the Caribbean are named Soufrière (French: "sulfur outlet"). These include La Soufrière or Soufrière Saint Vincent on the island of Saint Vincent, and La Grande Soufrière on Guadeloupe. After a long period of dormancy, the Soufrière Hills volcano became active in 1995 and has continued to erupt ever since. Its eruptions have rendered more than half of Montserrat uninhabitable, destroying the capital city, Plymouth, and causing widespread evacuations: about two thirds of the population have left the island. It is andesitic in nature, and the current pattern of activity includes periods of lava dome growth, punctuated by brief episodes of dome collapse which result in pyroclastic flows, ash venting, and explosive eruption. The volcano is monitored by the Montserrat Volcano Observatory. Volcanic gas emissions from this volcano are measured by a Multi-Component Gas Analyzer System, which detects pre-eruptive degassing of rising magmas, improving prediction of volcanic activity.

Western Caribbean Zone
The Western Caribbean Zone is a region consisting of the Caribbean coasts of Central America, from Yucatán in Mexico to northern Colombia, and also the islands west of Jamaica. The zone emerged in the late sixteenth century as the Spanish failed to completely conquer many sections of the coast, and northern European powers supported opposition to Spain, sometimes through alliances with local powers. Unsubdued indigenous inhabitants of the region included some Maya polities, and other chiefdoms and egalitarian societies, especially in Belize, eastern Honduras, Nicaragua, and Costa Rica. In addition, the region was the refuge of several groups of runaway slaves, who formed independent settlements or intermixed with the indigenous societies. The combination of unsubdued indigenous people, outlaws (pirates in this case), and an absence of outside control made it similar in some aspects to the American West or the Wild West, as the western half of North America is often called. Its long engagement with the English-speaking Caribbean made it an ideal conduit for trade from both the English colonies of the Caribbean, especially Jamaica, but also North America, which had been trading in the zone since the eighteenth century at least. The relatively low population and strategic location attracted United States -based transportation companies to promote infrastructure projects from railroads to the Panama Canal in the zone, and conjointly with that to introduce large-scale fruit production toward the end of the nineteenth century, often bringing in labor from the English-speaking Caribbean to assist. Unique elements of the region, relative to the population of Central America in general, is the high percentage of people of whole or partial African descent, and its cultural connections to English and the English-speaking Caribbean through language and religion.

Grongar Hill
Grongar Hill is located in the Welsh county of Carmarthenshire and was the subject of a loco-descriptive poem by John Dyer. Published in two versions in 1726, during the Augustan period, its celebration of the individual experience of the landscape makes it a precursor of Romanticism. As a prospect poem, it has been the subject of continuing debate over how far it meets artistic canons.

Kaunos
Kaunos (Carian: Kbid; Lycian: Khbide; Ancient Greek: Καῦνος; Latin: Caunus) was a city of ancient Caria and in Anatolia, a few km west of the modern town of Dalyan, Muğla Province, Turkey. The Calbys river (now known as the Dalyan river) was the border between Caria and Lycia. Initially Kaunos was a separate state; then it became a part of Caria and later still of Lycia. Kaunos was an important sea port, the history of which is supposed to date back till the 10th century BC. Because of the formation of İztuzu Beach and the silting of the former Bay of Dalyan (from approx. 200 BC onwards), Kaunos is now located about 8 km from the coast. The city had two ports, the southern port at the southeast of Küçük Kale and the inner port at its northwest (the present Sülüklü Göl, Lake of the Leeches). The southern port was used from the foundation of the city till roughly the end of the Hellenistic era, after which it became inaccessible due to its drying out. The inner or trade port could be closed by chains. The latter was used till the late days of Kaunos, but due to the silting of the delta and the ports, Kaunos had by then long lost its important function as a trade port. After Caria had been captured by Turkish tribes and the serious malaria epidemic of the 15th century AD, Kaunos was completely abandoned. In 1966 Prof. Baki Öğün started the excavations of ancient Kaunos. These have been continued up to the present day, and are now supervised by Prof. Cengiz Işık. The archeological research is not limited to Kaunos itself, but is also carried out in locations nearby e.g. near the Sultaniye Spa where there used to be a sanctuary devoted to the goddess Leto.

List of Minerals Approved by IMA (J)
This list includes those recognised minerals beginning with the letter J. The International Mineralogical Association is the international group that recognises new minerals and new mineral names, however minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date. This list contains a mixture of mineral names that have been approved since 1959 and those mineral names believed to still refer to valid mineral species (these are called "grandfathered" species). The list is divided into groups: The data was exported from mindat.org on 29 April 2005; updated up to 'IMA2018'. The minerals are sorted by name, followed by the structural group (rruff.info/ima and ima-cnmnc by mineralienatlas.de, mainly) or chemical class (mindat.org and basics), the year of publication (if it's before of an IMA approval procedure), the IMA approval and the Nickel–Strunz code. The first link is to mindat.org, the second link is to webmineral.com, and the third is to the Handbook of Mineralogy (Mineralogical Society of America).

Life Cycle Assessment of Carbon Supply Chains
Carbon supply chains require a lot of energy during the operation, contributing to an additional environmental impact. In fact, the increased and required energy in terms of fuel consumption per kWh in the presence of carbon dioxide capture is between 24 and 40% for new supercritical pulverized coal plants, 11 and 22% for natural gas combined cycle plants, and 14 and 25% for coal-fired integrated gasification combined cycle systems compared to the respective system without capture plants. To be sure that the considered supply chain reduces carbon dioxide emissions and other environmental impacts a life cycle assessment should be developed optimizing its design with the minimum burden.
