Holiday Lighting Technology
Holiday lighting technology has been subject to considerable development and variation since the replacement of candles by electric lights. While originally used during the Christmas holidays as Christmas lights, modern electric light arrays have become popular around the world in many cultures and are used both during religious festivals and for other purposes unconnected to any festivities.

Allelopathy of S. canadensis
Solidago canadensis L. is native to North America and have naturalized many other continents including Europa and Asia. Their species is an aggressive colonizer and forms thick monospecific stands. Allelopathy is the chemical interaction between donor plants and recipient plants through allelochemicals. Allelochemicals are produced in some plant parts and released into the vicinity of the donor plants, including their rhizosphere soil either by the root exudation, rainfall leachates, volatilization from the plant parts or decomposition processes of plant residues.

Coppermine Expedition of 1819–22
The Coppermine Expedition of 1819–1822 had as its goal the exploration of the northern coast of Canada , which was accessed by way of the Coppermine River. The British expedition was organised by the Royal Navy as part of its attempt to discover and map the Northwest Passage. It was the first of three Arctic expeditions to be led by John Franklin, and also included George Back and Dr. John Richardson, both of whom would become notable Arctic explorers in their own right. The expedition was plagued by poor planning, bad luck and unreliable allies. The expected assistance from the local fur trading companies and native peoples was less forthcoming than expected, and the dysfunctional supply line, coupled with unusually harsh weather and the resulting absence of game, meant that the explorers were never far from starvation. Eventually the Arctic coast was reached, but barely 500 mi (800 km) had been explored before the exhaustion of the party's supplies and the onset of winter forced it to turn back. The expedition made a desperate retreat across uncharted territory in a state of starvation, often with nothing more than lichen to eat. Eleven of the twenty-strong party died amid accusations of murder and cannibalism before the survivors were rescued by people of the Yellowknives First Nation, who had previously given them up for dead. In the aftermath of the expedition, Franklin was much criticised by local fur traders for his haphazard planning and failure to adapt to the circumstances he faced, but in Britain he was received as a hero, and fêted for the courage he had shown in extreme adversity. The expedition captured the public imagination, and in reference to a desperate measure he took while starving, he became known as "the man who ate his boots".

List of Minerals Approved by IMA (D)
This list includes those recognised minerals beginning with the letter D. 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).

Monitoring Control and Surveillance
Monitoring, control and surveillance (MCS), in the context of fisheries, is defined by the Food and Agriculture Organization (FAO) of the United Nations as a broadening of traditional enforcing national rules over fishing, to the support of the broader problem of fisheries management. Internationally, the basis of law for fisheries management comes from the 1982 United Nations Convention on the Law of the Sea (UNCLOS). Further definition was in the Declaration of Cancun This is complemented by the work of a variety of regional organizations that cover high seas fishing areas. A key concept in international fishing laws is that of the Exclusive Economic Zone, which extends 200 miles (370 km) from the coast of nations bordering on the oceans. EEZ is not a meaningful concept in relatively small seas such as the Mediterranean and Baltic, so those areas tend to have regional agreements for MCS of international waters within those seas.

Remote Sensing of Geomorphodiversity Linked to Biodiversity
Remote sensing (RS) enables a cost-effective, extensive, continuous and standardized monitoring of traits and trait variations of geomorphology and its processes, from the local to the continental scale. RS technologies can record geomorphic traits, their diversity and variations, from which the other four geomorphodiversity characteristics are derived. However, compared to in situ measurements, RS approaches can only record certain parts of these geomorphic traits and their variations. This is because capturing geomorphic traits and diversity using RS approaches is limited by various constraints, namely: (1) the characteristics and spatial-temporal distribution of geomorphic traits; (2) the characteristics of geomorphological processes; as well as (3) the RS sensor characteristics, the chosen RS platforms and the characteristics of RS data-processing and classification information. These constraints and limitations define the detectability, feasibility, accuracy, depth of information, repeatability, and, thus, standards disability in monitoring the five geomorphic characteristics using RS approaches.

UC Berkeley College of Natural Resources
The College of Natural Resources (CNR), a college of the University of California, Berkeley, is the oldest college in the UC system and home to several internationally top-ranked programs. CNR's Department of Agriculture & Economics is considered to be one of the most prestigious schools in agricultural economics in the world, ranking #1 according to the Journal of Agricultural and Applied Economics, #1 by the Chronicle of Higher Education, #1 by Perry for its Ph.D. programs and in International Trade, #1 by the National Research Council in Agricultural & Resource Economics, and #1 by U.S. News in Environmental/Environmental Health. In environmental disciplines, QS World Rankings recognizes the University of California, Berkeley, as the world's leading university in Environmental Studies with 100 points in Academic Reputation. U.S. News also ranks it as the best global university for environment and ecology. A study of AJAE authors and their university affiliations found it to have the highest number of pages per research faculty member. Established in 1868 as the College of Agriculture under the federal Morrill Land-Grant Acts, CNR is the first state-run Agricultural Experiment Station. The college is home to four academic departments: Agriculture and Resource Economics; Environmental Science, Policy, and Management; Nutritional Sciences and Toxicology; and Plant and Microbial Biology, and one interdisciplinary program, Energy and Resources Group. Faculty include 40 Fulbright Fellows, 30 American Association for the Advancement of Science Fellows, 19 National Academy of Sciences members, 12 Guggenheim Fellows, 9 American Academy of Arts and Sciences members, 7 MacArthur Fellows, 4 Nobel Laureates, 3 Wolf Prize winners, and 2 World Food Prize winners. The Dean of the College is Prof. David Ackerly.

Ecotourism Development in Russian Areas under Nature Protection
Ecotourism has become an important area of development for Russian protected areas (PAs), which have begun to offer a variety of ecotourism services. Russia, along with other countries, adheres to a variety of concepts and tools for the development of ecotourism in PAs. Efforts are being made in the parks to create favorable conditions for ecotourism development. These efforts include improving management practices, implementing functional zoning strategies, developing conceptual and design solutions, developing infrastructure, securing funding, engaging local communities, and promoting ecotourism services.
