Aydın
Aydın (/ˈaɪdɪn/ EYE-din; Turkish: [ˈajdɯn]; formerly named Güzelhisar, Ancient and Modern Greek: Τράλλεις /Tralleis/) is a city in and the seat of Aydın Province in Turkey's Aegean Region. The city is located at the heart of the lower valley of Büyük Menderes River (ancient Meander River) at a commanding position for the region extending from the uplands of the valley down to the seacoast. Its population was 207,554 in 2014. Aydın city is located along a region which was famous for its fertility and productivity since ancient times. Figs remain the province's best-known crop, although other agricultural products are also grown intensively and the city has some light industry. At the crossroads of a busy transport network of several types, a six-lane motorway connects Aydın to İzmir, Turkey's second port, in less than an hour, and in still less time to the international Adnan Menderes Airport, located along the road between the two cities. A smaller airport, namely Aydın Airport, is located a few kilometers in the South-East of Aydın. The region of Aydın also pioneered the introduction of railways into Turkey in the 19th century and still has the densest railroad network. The province of Aydın is also where a number of internationally known historic sites and centers of tourism are concentrated.

Landscape Connectivity
Landscape connectivity in ecology is, broadly, "the degree to which the landscape facilitates or impedes movement among resource patches". Alternatively, connectivity may be a continuous property of the landscape and independent of patches and paths. Connectivity includes both structural connectivity (the physical arrangements of disturbance and/or patches) and functional connectivity (the movement of individuals across contours of disturbance and/or among patches). Functional connectivity includes actual connectivity (requires observations of individual movements) and potential connectivity in which movement paths are estimated using the life-history data. The degree to which a landscape is connected determines the amount of dispersal there is among patches, which influences gene flow, local adaptation, extinction risk, colonization probability, and the potential for organisms to move as they cope with climate change.

Crop Sustainability and Five Domains in Mediterranean Region
Most of the Mediterranean region has experienced frequent natural disasters, expanding population, increase in temperature, and increase in the surface of the Mediterranean Sea. Furthermore, the temperature in the Mediterranean area is rising 25% faster than the rest of the globe, and in the summer, it is warming 40% faster than the global average. Climate change can alter the food supply, restrict access to food, and degrade food quality. Temperature rises, changes in precipitation patterns, changes in severe weather events, and decreased water availability, for example, might all result in lower agricultural production. The fact that most Mediterranean nations rely on imported basic foodstuffs adds to the severity of the situation. Instability and insecurity of agricultural supply in the region might lead to massive population movement, transforming most Mediterranean nations into a global source of instability.

Yana, India
Yana is a village located in forests of the Sirsi and Kumta Uttara Kannada district of Karnataka, India which is known for the unusual karst rock formations. It is located in the Sahyadri mountain range of the Western Ghats, about 60 kilometres (37 mi) from Karwar port, 39 kilometres (24 mi) from Sirsi, and 31 kilometres (19 mi) from Kumta. Yana is one of the wettest villages in the world. It is the cleanest village in Karnataka, and the second cleanest village in India . The two unique rock outcrops near the village are a tourist attraction and easily approachable by a small trek through 0.5 kilometres (0.31 mi) of thick forests from the nearest road head. Yana is famous for these two massive rock outcrops known as the Bhairaveshwara Shikhara and the Mohini Shikhara ("Shikhara" means "hill"). The huge rocks are composed of solid black, crystalline karst limestone. Bhairaveshwara Shikhara is 120 metres (390 ft) in height, while the Mohini Shikhara, which is smaller, is 90 metres (300 ft) in height. Yana is also well known as a pilgrimage centre because of the cave temple below the Bhairaveshwara Shikhara where a Swayambhu ("self manifested", or "that which is created by its own accord") linga has been formed. Water drips from the roof over the linga, adding to the sanctity of the place. During Shivaratri here, a car festival is held, along with other festivities. The place and its surrounding hillocks are also known for their evergreen scenic forests.

Biochronology
In paleontology, biochronology is the correlation in time of biological events using fossils. In its strict sense, it refers to the use of assemblages of fossils that are not tied to stratigraphic sections (in contrast to biostratigraphy, where they are). Collections of land mammal ages have been defined for every continent except Antarctica, and most are correlated with each other indirectly through known evolutionary lineages. A combination of argon–argon dating and magnetic stratigraphy allows a direct temporal comparison of terrestrial events with climate change and mass extinctions.

Green Goldmining
Green goldmining was proposed since goldmining has brought about hardship in local communities through pollution of water and air; lost grazing and agricultural land; the creation of unprotected mining pits; exploitation and depletion of natural resources; as well as forced eviction and relocation of communities without fair compensation. Environmental management accounting practices are suggested to facilitate greener goldmining processes.

Food Systems
The term food system is used frequently in discussions about nutrition, food, health, community economic development and agriculture. A food system includes all processes and infrastructure involved in feeding a population: growing, harvesting, processing, packaging, transporting, marketing, consumption, and disposal of food and food-related items. It also includes the inputs needed and outputs generated at each of these steps. A food system operates within and is influenced by social, political, economic and environmental contexts. It also requires human resources that provide labor, research and education. Food systems are either conventional or alternative according to their model of food lifespan from origin to plate.

Pyrolysis of Biosolids to Produce Biochars
Biochar is a solid, charcoal material that can be used in different applications such as its use in agriculture as a soil enhancer in which moisture content is sustained for long periods of times. Biosolids or biosludges will refer to any form of sludge that has undergone some form of treatment (e.g., chemical, biological, heat treatment, etc.) in order to transform it into a less hazardous and organic form. More importantly, there seems to be an inconsistency in defining what classifies as biosolids, hence, a unified definition is established and provided. The aim is to enable the scientific community as a whole to use a standard definition that allows for synergies to take place. Specifically, the pyrolysis process is selected and is known as a thermochemical technique in which heat and an oxygen-free environment facilitate the decomposition of the feedstock into different products, depending on the operating parameters.

Teaching Sustainability in Planning and Design Education
Education for sustainable development (ESD) benefits school improvement and individual students, allowing them to ask critical questions about the status quo, clarify their values, and think systemically. In the fields of planning and design, including urban planning, regional planning, landscape architecture, and urban design, sustainability is vital to address the development dilemmas of environmental protection, urban development, economic activity, and social expectations. Design and planning decisions must consider a wide range of activities representing the goals of preservation, development, economic opportunities, social justice, and many others.

Trindade and Martin Vaz
Trindade and Martin Vaz (Portuguese: Trindade e Martim Vaz, pronounced [tɾĩˈdadʒi i mɐʁˈtʃĩ ˈvas]) is an archipelago located in the South Atlantic Ocean about 1,100 kilometres (680 miles) east of the coast of the Brazilian state of Espírito Santo, of which it forms a part. The archipelago has a total area of 10.4 square kilometres (4.0 square miles) and a population of 32 (Brazilian Navy personnel).The archipelago consists of five islands and several rocks and stacks; Trindade is the largest island, with an area of 10.1 square kilometres (3.9 square miles); about 49 kilometres (30 miles) east of it are the tiny Martin Vaz islets, with a total area of 0.3 square kilometres (30.0 hectares). The islands are of volcanic origin and have rugged terrain. They are largely barren, except for the southern part of Trindade. They were discovered in 1502 by Portuguese explorer Estêvão da Gama and stayed Portuguese until they became part of Brazil at its independence in 1822. From 1895 to 1896, Trindade was occupied by the United Kingdom until an agreement with Brazil was reached. During the period of British occupation, Trindade was known as South Trinidad. The islands are situated some 2,100 kilometres (1,300 miles) southwest of Ascension Island and 2,550 kilometres (1,580 miles) west of Saint Helena, and the distance to the west coast of Africa is 4,270 kilometres (2,650 miles).

January 1938 Geomagnetic Storm
Infobox storm The 25–26 January 1938 geomagnetic storm (also titled the Fátima Storm) was a massive solar storm which occurred 16–26 January with peak activity on 22, 25, and 26 January and was part of the 17th solar cycle. The electrification of Europe and North America was still in its infancy, therefore the light storm could be seen brilliantly. The intensely bright arches of crimson light with shifting spectrum of green, blue-white, and red radiated from a brilliant Auroral Crown near the Zenith instead of appearing as usual in parallel lines. This Aurora is believed by many people, especially those of the Catholic faith, to be related to the Fátima Prophecies (explained below). On January 25–26th, 1938, the sky was lit up with an Aurora Borealis light storm, seen all across the world. The storm was identical to other storm induced, low-latitude aurora borealis. The great Aurora that was witnessed across Europe, the Americas, and Oceania had not been seen/documented in Europe since 1709, and in the Americas since 1888. The storm was remarkable primarily because of how far and wide it was observed, and for the brightness of its green strip lights and red glow, which led many to believe the cause was a fire. Reports collected at the time show that the Aurora was witnessed in the far north of Canada, and spread as far south as Southern California and on Bermuda in the North Atlantic off of the Carolinas. In Europe, the aurora was seen in Northern Scotland, East Austria, in southern Sicily, Gibraltar, and Portugal. This magnificent display of lights was experienced across the world, as reported in different news archives. The lights sent some into panic, as many were awestruck, astonished by the rarity of the experience. Canada experienced the most vivid auroral displays on the nights of January 24–26. In the Netherlands people were awaiting the imminent birth of Princess Juliana's baby Princess Beatrix who was eventually born on 31 January 1938: the Dutch considered the aurora as a lucky omen. In Salzburg, Austria, some residents called on the fire department as they believed something was on fire. Alarm bells were rung into a frenzy that night and the fire departments were constantly sounding new alarms trying to calm the citizens. The loud multitude of ringing further caused panic, causing some residents to flee to more rural areas. The same fright was seen in London where many also believed whole streets were on fire, even the guards of Windsor Castle summoned the fire brigade to put out the said "fire". In Switzerland, the snow-covered peaks of the Swiss Alps were glowing bright and reflecting some of the Auroral rays causing a reflective disco effect. In Descanso, San Diego, the National Forest Service was alerted on the night of January 22nd to respond to a "great fire in the backcountry"; after they checked out the back roads they discovered it was the crimson Aurora Borealis in the northern sky, which had not been seen in that region since February 1888. In Bermuda, many people believed that a massive freight ship was on fire at sea. Steamship captains were calling the wireless stations to learn if there were any S.O.S calls and if they could help. In Scotland, religious individuals living in the lowlands believed the Aurora to be an ill-omen for Scotland. The electrical side effects of the light storm were limited because, at that time, electricity had not been advanced to our modern technological standards. Short-wave radio transmissions were shut down for almost 12 hours in Canada. In England, the signaling equipment line on the Manchester-Sheffield express trains was inoperable due to electrical disturbances. These coal trains were halted in their movement and waited at these junctions for safety reasons. Teletype systems at the New York Western Union offices began to spew out garbage data, suffering electrical shortages.

Jeannette Expedition
The Jeannette Expedition of 1879–1881, officially called the U.S. Arctic Expedition, was an attempt led by George W. De Long to reach the North Pole by pioneering a route from the Pacific Ocean through the Bering Strait. The premise was that a temperate current, the Kuro Siwo, flowed northwards into the strait, providing a gateway to the Open Polar Sea and thus to the pole. This theory proved illusory; the expedition's ship, USS Jeannette and its crew of 33, was trapped by ice and drifted for nearly two years before she was crushed and sunk, north of the Siberian coast. De Long then led his 32 men on a perilous journey by sled, dragging the Jeannette's whaleboat and two cutters, eventually switching to these small boats to sail for the Lena Delta in Siberia. During this journey, and in the subsequent weeks of wandering in Siberia before rescue, 20 of the ship's complement died, including De Long. The chief exponent of the theory of a warm-water gateway to the North Pole was the German cartographer August Petermann. He encouraged James Gordon Bennett Jr., the proprietor of the New York Herald, to finance a polar expedition based on the untried Pacific route. Bennett acquired a former Royal Navy gunboat, the Pandora, and changed her name to Jeannette. De Long, whom Bennett chose to lead the expedition, was a serving naval officer with previous Arctic experience. Although essentially a private venture, in which Bennett paid all the bills, the expedition had the full support of the U.S. Government. Before departure the ship was commissioned into the U.S. Navy as USS Jeannette, and sailed under navy laws and discipline. Before its demise, the expedition discovered new islands—the De Long Islands—and collected valuable meteorological and oceanographic data. Although Jeannette's fate demolished the widely believed Open Polar Sea theory, the appearance in 1884 of debris from the wreck on the south-west coast of Greenland indicated the existence of an ocean current moving the permanent Arctic ice from east to west. This discovery inspired Fridtjof Nansen to mount his Fram expedition nine years later. A monument to the Jeannette's dead was erected at the United States Naval Academy in Annapolis, in 1890.

Role of ACE2 in Gut
A vital factor of viral pathogenesis involves the angiotensin-converting enzyme-2 (ACE2) cellular receptor, which facilitates entry of the virus into susceptible cells. The receptor-binding domain of the spike protein binds to the ACE2 receptor activating membrane fusion of the virus to the host cell. Subsequently, viral RNA is released into the cytoplasm, and the infection is established. The gut microbiota is shaped by our diet; therefore, a healthy gut is important for optimal metabolism, immunology and protection of the host.

Mortuary Archaeology
Mortuary archaeology, also known as bioarchaeology, is the study of human remains in their archaeological context. Mortuary archaeology aims to generate an understanding of disease, migration, health, nutrition, gender, status, and kinship among past populations. Ultimately, these topics help to produce a picture of the daily lives of past individuals. Mortuary archaeology tends to focus how individuals can contribute to understanding the population. Mortuary archaeologists draw upon the humanities, as well as social and hard sciences to have a full understanding of the individual. Mortuary archaeologists also use living groups to their advantage when studying populations that are no longer living. Mortuary archaeologists also are involved in conflict archaeology, and study mass burials from different historical events, like World War II and the Guatemalan genocide. These particular events will deal with comingled individuals. However, not all events are involved in mass burials or of historic context. One instance of a single individual involved in conflict, is that of Otzi. This is an example of a single individual that had been shot and killed. There are different methods that contribute to mortuary archaeology including analyzing different burial techniques between and within populations and creating a biological profile of the individual(s).

Global 200
The Global 200 is the list of ecoregions identified by WWF, the global conservation organization, as priorities for conservation. According to WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species dynamics, and environmental conditions". So, for example, based on their levels of endemism, Madagascar gets multiple listings, ancient Lake Baikal gets one, and the North American Great Lakes get none. The WWF assigns a conservation status to each ecoregion in the Global 200: critical or endangered; vulnerable; and relatively stable or intact. Over half of the ecoregions in the Global 200 are rated endangered.
