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.

Influence Radius of Pumping Well
The influence radius was originally used in the calculation of some hydrogeological parameters but, owing to various coincidences that occur in practical situations, it has been considered that the parameterized influence radius is reasonable and convenient for calculations pertaining to actual production problems, and this misconception has perpetuated. However, by considering the continuity principle of flow, it can be proven that the parameterized influence radius does not exist. The influence radius is essentially the distance in the time–distance problem in physics and is influenced by the hydrogeological conditions and pumping conditions, which is different from the hydrogeological parameters reflecting the natural properties of aquifers, such as the porosity, specific yield, and hydraulic conductivity.

Incineration Bottom Ash from Municipal Solid Waste
Incineration bottom ash (IBA) is the main residue from municipal solid waste (MSW) incineration and refers to the incombustible materials that remain in the furnace after combustion. IBA is a very heterogeneous material, comprising irregularly shaped particles and a wide particle size distribution. This material is a complex inorganic mixture generally composed of melt products, minerals, metallic compounds, ceramics, and glass [1]. The classification and the management practices of IBA differ worldwide and, particularly, among the EU Member States. However, different applications have been studied for this material.

Influence of Technologies on Sustainable Tourism
This study’s objective is to provide an overview on literature state-of-the-art related to sustainable tourism and technological innovations, offering insights for further advancing this domain. We employ a bibliometric analysis and a comprehensive review of 139 articles, collected from Web of Science and Scopus databases, for the purpose of: (i) exploring and discussing the most relevant contributions in the publication network: (ii) highlighting key issues and emerging topics; (iii) uncovering open questions for the future. Our findings reveal contradictory views on the risks and benefits of technology adoption. Artificial intelligence, internet of things, circular economy, big data, augmented and virtual reality emerge as major trends. Five work streams are identified and described, leading to a broader perspective on how technology can shape the future of sustainable tourism. Relevant theoretical and managerial implications are derived. Finally, a research agenda is proposed as guidance for future studies addressing the outcomes of digital disruption on sustainable tourism.

Astana
Astana, previously known as Akmolinsk, Tselinograd, Akmola and most recently Nur-Sultan, is the capital city of Kazakhstan. The city lies on the banks of the Ishim River in the north-central part of Kazakhstan, within the Akmola Region, though administered as a city with special status separately from the rest of the region. A 2020 official estimate reported a population of 1,136,008 within the city limits, making it the second-largest city in the country, after Almaty, which had been the capital until 1997. The city became the capital of Kazakhstan in 1997; since then it has grown and developed economically into one of the most modern cities in Central Asia. In 2021, the government selected Astana as one of the 10 priority destinations for tourist development. Modern Astana is a planned city, following the process of other planned capitals. After it became the capital of Kazakhstan, the city dramatically changed its shape. The city's master-plan was designed by Japanese architect Kisho Kurokawa. As the seat of the government of Kazakhstan, Astana is the site of the Parliament House, the Supreme Court, the Ak Orda Presidential Palace and numerous government departments and agencies. It is home to a range of futuristic buildings, including many skyscrapers.

Plastic Waste Governance in Bangladesh
Plastic, an offer of modernity, is presenting a massive threat in altered forms, to our health and environment. Plastic does not only pollute the surface environment, fresh water, and marine ecosystems, but toxic elements released from plastics also percolate down the surface and contaminate groundwater, which we often use as ‘safe’ drinking water. This probable future risk is deeply rooted in the entire governance infrastructure of plastic waste which could potentially lead to contamination of groundwater. A recent study finds 81% of tap water samples collected worldwide contained plastic pollutants, which means that annually we may be ingesting between 3000 and 4000 microparticles of plastic from tap water.

Seaweeds in Producing Safe and Sustainable Bio-Packaging
Diverse studies demonstrate that seaweed polysaccharides (e.g., alginates and carrageenans) not only provide health benefits, but also contribute to the production of biopolymeric film and biodegradable packaging. The dispersion of plastics and microplastics in the oceans provoke serious environmental issues that influence ecosystems and aquatic organisms. Thus, the sustainable use of seaweed-derived biopolymers is now crucial to replace plasticizers with biodegradable materials, and thus preserve the environment.

Aquaculture Food Production in Portugal
World aquaculture food production rises every year, amounting, by 2018, to another all-time record of 82.1 million tonnes of farmed seafood, with Asia leading global production. In Europe, although coastal countries present historical fishing habits, aquaculture is in true expansion. Norway, the leading European producer, is the eighth main producer worldwide. Portugal is a traditional fishing country but has invested in the development of aquaculture for the past decade, attaining, by 2018, 13.3 tonnes produced, making Portugal the 16th main producer amongst European Union member states that year. Most Portuguese aquaculture facilities operate in coastal systems, resorting to extensive and semi-intensive rearing techniques. In Portugal, marine food production in transitional systems is particularly interesting as the practice has, worldwide, been continuously substituted by intensive methods. In fact, facilities in transitional systems have developed over time and products gained higher commercial value.

Agriculture in Ancient Mesopotamia
Agriculture was the main economic activity in ancient Mesopotamia. Operating under harsh constraints, notably the arid climate, the Mesopotamian farmers developed effective strategies that enabled them to support the development of the first states, the first cities, and then the first known empires, under the supervision of the institutions which dominated the economy: the royal and provincial palaces, the temples, and the domains of the elites. They focused above all on the cultivation of cereals (particularly barley) and sheep farming, but also farmed legumes, as well as date palms in the south and grapes in the north. In reality, there were two types of Mesopotamian agriculture, corresponding to the two main ecological domains, which largely overlapped with cultural distinctions. The agriculture of southern or Lower Mesopotamia, the land of Sumer and Akkad, which later became Babylonia received almost no rain and required large scale irrigation works which were supervised by temple estates, but could produce high returns. The agriculture of Northern or Upper Mesopotamia, the land that would eventually become Assyria, had enough rainfall to allow dry agriculture most of the time so that irrigation and large institutional estates were less important, but the returns were also usually lower.

CP4-EPSPS
CP4-EPSPS (Agrobacterium sp. strain CP4 5-enolpyruvylshikimate-3-phosphate synthase) protein showed remarkable thermostability and was highly resistant to proteases, such as trypsin. However, some proteases are able to degrade CP4-EPSPS efficiently. Therefore, these proteases may play key roles in elimintating the pollution of CP4-EPSPS to the environment.

Eco-Art Place-Based Education
The existing state of the world climate creates the need for an educational programme that incorporates effective proposals for the environment that can be practically implemented. The present environmental education literature has changed due to new study paradigms. Understanding how students relate to nature, how their personal beliefs and behaviours are influenced, and how their actions are affected can provide an increased understanding of how they can contribute meaningfully to global objectives. This paper aims to analyse educational research papers published in the area of environmental art education in order to find the factor with the greatest effect and illuminate how they can help to improve the measures implemented.

Carbon Capture Utilization and Storage in Korea
In 2008, the Republic of Korea announced the Low Carbon Green Growth vision as the national growth engine. This Green Growth vision invested in developing state-of-the-art green technologies to minimize greenhouse gas and pollutant emissions. Following a change in administration, Korean green technologies were re-categorized into six core technologies for climate change response in 2014, and ten core technologies for carbon-neutrality in 2021. The government proposed the realization of an inclusive green state in the 3rd Five-Year Green Growth Plan announced in 2019. Following the Green New Deal announced in 2020, green technology policies and investments continue, with the declaration of 2050 carbon neutrality. In the past two years, government policies from the 2050 Carbon Neutrality Strategy to the 2050 Carbon-Neutral Scenario consider Carbon Capture Utilization and Storage (CCUS) as an important technology to reduce CO2 and meet carbon-neutral goals.

Blockchain Technology and Tokenization
Blockchain is an open-source technology that excludes the traditional third parties by relying on collective verification, thus offering a great alternative in terms of costs, traceability, security, and speed. When two financial entities such as banks receive a request to transfer money from one account to another, they have to update the balances of their respective customers. This costly and time-consuming coordination and synchronization exercise can be simplified on a blockchain by using a single ledger of transactions reflecting a single version of records instead of two different databases. Blockchain technology offers a myriad of value through a frictionless process of immutable and transparent records and through converting assets into digital tokens (i.e., tokenization) with smart contracts.

Classified Urban Land Cover Classes
The urban land cover consists of very complex physical materials and surfaces that are constantly having anthropological impacts. The urban surface types are a mosaic of seminatural surfaces such as grass, trees, bare soil, water bodies, and human-made materials of diverse age and composition, such as asphalt, concrete, roof tiles for energy conservation and fire danger, and generally impervious surfaces for urban flooding studies and pollution. The complexity of urban analysis also depends on the scale chosen and its purpose.
