Life Cycle Thinking for a Circular Bioeconomy
The circular bioeconomy (CBE) is an increasingly popular method used to add value to bio-based products. However, these products entail impacts on sustainability that can be assessed by life cycle thinking (LCT). LCT is an approach to assess the impacts of products throughout their life cycles by using different tools, namely: (environmental) life cycle assessment (LCA), life cycle costing (LCC), social life cycle assessment (SLCA) and life cycle sustainability assessment (LCSA), which is a combination of the three and aims to assess the impacts of all of the three dimensions of sustainability.

Life Cycle Zero Energy Building (LC-ZEB)
A life cycle zero energy building (LC-ZEB) is defined here as a building whose primary energy use in operation plus the energy embedded in materials and systems over the life of the building is equal or less than the energy produced by renewable energy systems within the building.

Light-Based Removal of Emerging Contaminants
Contaminants of emerging concern (CECs) are currently an unregulated class of contaminants with increasing global presence and awareness. However, the management of CECs in water bodies is particularly challenging due to the difficulty in detection and their recalcitrant degradation by conventional means. Light-based oxidation processes are viable options for such application. Light-driven oxidation processes use light as an irradiation source to generate oxidative species for the degradation of emerging contaminants. The key few technologies available are discussed in the review article: photo/Fenton, photocatalysis, photolysis, UV/Ozone. Herein, a cost–benefit analysis on various light-based processes was conducted to access the suitability for CECs degradation. It was found that the UV/Ozone process might not be suitable due to the complication with pH adjustments and limited light wavelength. It was found that EEO values were in this sequence: UV only > UV/combination > photocatalyst > UV/O3 > UV/Fenton > solar/Fenton. The solar/Fenton process has the least computed EEO < 5 kWh m−3 and great potential for further development. Newer innovations such as solar/catalyst can also be explored with potentially lower EEO values. Light-based processes could also be used to detect CECs in surface water. Hence forming the 2 pronged approach for CEC management.

Lignocellulosic Biofuels: A Renewable Bioenergy
Biofuel consists of non-fossil fuel derived from the organic biomass of renewable resources, including plants, animals, microorganisms, and waste. Energy derived from biofuel is known as bioenergy. The reserve of fossil fuels is now limited and continuing to decrease, while at the same time demand for energy is increasing. In order to overcome this scarcity, it is vital for human beings to transfer their dependency on fossil fuels to alternative types of fuel, including biofuels, which are effective methods of fulfilling present and future demands. The conversion of lignocellulosic feedstock is an important step during biofuel production. It is, however, important to note that, as a result of various technical restrictions, biofuel production is not presently cost efficient, thus leading to the need for improvement in the methods employed.

Lignocellulosic Biomass as a Renewable Source
Lignocellulosic biomass is the primary structural component of plant matter and is mostly inedible, generally referring to organic materials such as wood, grass, and agricultural crop residues. Biomass is a plentiful and carbon-neutral renewable energy source that may be used to create platform chemicals and fuels, especially considering that up to 75% of initial energy can be converted into biofuels.

List of Assyrian Tribes
This page features a list of Assyrian clans or tribes historically centered in the Hakkari, Sirnak and Mardin provinces in Turkey and West Azerbaijan Province in Iran, prior to 1915, or before Seyfo, when they were historically Assyrian settlements, before early 20th century resettlement in Northern Iraq (which simultaneously had Catholic-Assyrian tribes since the 1st millennium) and northwestern Syria (namely in Al-Hasakah) after they were displaced, slaughtered and driven out by Ottoman Turks in 1915 and in the early 1930s, respectively, during the Simele massacre where they endured a similar anguish and predicament. From around 2500 BC, Assyrians primarily lived in the ancient Assyrian cities of Nineveh, Assur, Nohadra, Arrapha and Arbela, which now lie in modern-day northern Iraq, and as well as the mountainous Assyrian region of Hakkari in what is now Turkey, from around 2300 BC. Though after the spread of Islam, many eventually left the ancient Assyrian cities in the Nineveh Plains, where they settled and found refuge in the highland region in southeastern Anatolia, with the existing Assyrian population, and northwestern Iran. The villages in southeastern Turkey are primarily centred in the modern-day towns of Yuksekova, Çukurca and Semdinli in Hakkâri, Uludere in Sirnak Province and Tur Abdin in Mardin Province. Most of the historical Assyrian tribes are located in the region stretching from Tur Abdin to Hakkari, in Upper Mesopotamia, which formed the Nairi lands, serving as the northern Assyrian frontier and border with their Urartian rivals. The Assyrians of this region were Nestorian Christians adhering to the Assyrian Church of the East and lived here until 1924, when the very last Assyrians who survived the Assyrian Genocide and massacres that occurred during 1918 were expelled. Most subsequently moved to the Nahla valley in northern Iraq or elsewhere. The people of these tribes are an ancient people of Mesopotamia who speak Assyrian Neo-Aramaic, a modern Syriac language that's derived from old Aramaic and has influences of Akkadian. In the early-mid 20th century, most settled in Iraq, Jordan, Syria and Iran, where many eventually immigrated to the western world in recent years.

List of Cities by Sunshine Duration
The following is a list of cities by sunshine duration. Sunshine duration is a climatological indicator, measuring duration of sunshine in given period (usually, a day or a year) for a given location on Earth, typically expressed as an averaged value over several years. It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period. Sunshine duration is usually expressed in hours per year, or in (average) hours per day. The first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location. Another often-used measure is percentage ratio of recorded bright sunshine duration and daylight duration in the observed period. An important use of sunshine duration data is to characterize the climate of sites, especially of health resorts. This also takes into account the psychological effect of strong solar light on human well-being. It is often used to promote tourist destinations.

List of Extreme Temperatures in Vatican City
The following list shows the readings of the maximum and minimum temperatures for each year from 1862 to the present, recorded in the weather station of the Collegio Romano in Rome, established in 1788. The station, actually located in the Italian territory, was opened when Rome was part of the Papal States. The first weather station in the Vatican state was opened only in 2009, and is placed in the Palace of the Governorate of Vatican City.
