Radon Flux Characteristics
Radon is a noble radioactive gas, and almost half of the effective doses from all ionising radiation comes from exposure to radon and its short-lived decay products. Radon flux measurements provide information about how much radon rises from the ground toward the atmosphere, thus, they could serve as good predictors of indoor radon concentrations. Although there are many different mapping methods with many different input data, radon flux data are generally missing and are not included for the delineation of radon priority areas (RPA).

Low-Carbon Travel Motivation and Constraint
Carbon dioxide emissions resulting from travel and tourism activities account for 5–14% of the world’s total carbon dioxide emissions. They are rising at a rate of 3.2% per year. Transportation (e.g., aircraft, cars, and boats), accommodation, and tourism activities represent the primary means tourism consumes energy and produces carbon emissions. Jarratt and Davies have asserted that tourists could slow the rise in carbon emissions, by consuming less fuel and reducing their carbon emissions. Thus, promoting low-carbon travel has become a topic of interest to the tourism industry and academic circles over the past ten to twenty years.

Using Remote Sensing to Detect Suspended Sediment
Glacier-fed hydrological systems in high latitude regions experience high seasonal variation in meltwater runoff. The peak in runoff usually coincides with the highest air temperatures which drive meltwater production. This process is often accompanied by the release of sediments from within the glacier system that are transported and suspended in high concentrations as they reach the proglacial realm. Sediment-laden meltwater is later transported to the marine environment and is expressed on the surface of fjords and coastal waters as sediment plumes. Direct monitoring of these processes requires complex and time-intensive fieldwork, meaning studies of these processes are rare.

Deep Supervision-Based Simple Attention Network
Semantic segmentation for remote sensing images (RSIs) plays an important role in many applications, such as urban planning, environmental protection, agricultural valuation, and military reconnaissance. With the boom in remote sensing technology, numerous RSIs are generated; this is difficult for current complex networks to handle. Efficient networks are the key to solving this challenge.

Australia Electric Vehicles Charging Infrastructure
Electric vehicle (EV) adoption is growing worldwide with increasing market pull from consumers and market push from manufacturers of vehicles and charging equipment, as well as others in the supply chain. Governments have begun developing policies to support EV uptake and local governments, in particular, are examining what role they should play. In Australia, a large country with low population density, EV uptake has been slower in comparison to other similar economies.

Towards Circular Economy for More Sustainable Apparel Consumption
The apparel industry causes environmental problems, particularly due to the shortening life cycle of garments and fast-fashion’s throw-away culture. The circular economy provides solutions to minimise and prevent these problems through innovative circular business models, which require changes in consumer behaviours. With the lens of environmental psychology, we analyse consumers’ willingness to acquire circular apparel considering four approaches on clothing life-cycle extension. We conducted an online questionnaire among Brazilian and Dutch consumers and tested if the Value-Belief-Norm (VBN) theory can explain the willingness of consumers to purchase circular apparel. Our results indicate that, overall, the variables from the VBN theory explain circular behaviour in the apparel industry and that the paths suggested by the model are supported by our analyses. Additionally, we tested and found that when all of the variables from the VBN theory were controlled for, materialistic values did not explain circular behaviours in the apparel industry among Brazilian respondents. However, they had a positive influence on some circular apparel behaviours among Dutch consumers. Overall, materialistic values did not play an important role in predicting willingness to consume circular clothing. Furthermore, the results suggest that the VBN theory predicts willingness to consume circular apparel better in the Netherlands compared to Brazil, suggesting that this behaviour may be perceived as more effortful for the Brazilian population. However, we highlight the need for future research.

Sulfate Minerals
The sulfate minerals are a class of minerals that include the sulfate ion (SO42−) within their structure. The sulfate minerals occur commonly in primary evaporite depositional environments, as gangue minerals in hydrothermal veins and as secondary minerals in the oxidizing zone of sulfide mineral deposits. The chromate and manganate minerals have a similar structure and are often included with the sulfates in mineral classification systems. Sulfate minerals include:

Cartography of Jerusalem
The cartography of Jerusalem is the creation, editing, processing and printing of maps of Jerusalem from ancient times until the rise of modern surveying techniques. Almost all extant maps known to scholars from the pre-modern era were prepared by Christian mapmakers for a Christian European audience. Maps of Jerusalem can be categorized between original factual maps, copied maps and imaginary maps, the latter being based on religious books. The maps were produced in a variety of materials, including parchment, vellum, mosaic, wall paintings and paper. All maps marking milestones in the cartography of Jerusalem are listed here following the cartographic histories of the city, from Titus Tobler and Reinhold Röhricht's studies in the 19th century to those of Hebrew University of Jerusalem academics Rehav Rubin and Milka Levy-Rubin in recent decades. The article lists maps that progressed the cartography of Jerusalem before the rise of modern surveying techniques, showing how mapmaking and surveying improved and helped outsiders to better understand the geography of the city. Imaginary maps of the ancient city and copies of existing maps are excluded. The Madaba Map is the oldest known map of Jerusalem, in the form of a mosaic in a Greek Orthodox Church. At least 12 maps survive from the Catholic mapmakers of the Crusades; they were drawn on vellum and mostly show the city as a circle. The first printed map of the city was drawn by Erhard Reuwich and published in 1486 by Bernhard von Breydenbach in his Peregrinatio in Terram Sanctam, based on his pilgrimage of 1483. Approximately 500 maps are known between the late-1400s and the mid-1800s; the significant increase in number is due to the advent of the printing press. Few of the mapmakers had travelled to Jerusalem – most of the maps were either copies of others' maps or were imaginary (i.e. based on reading of religious texts) in nature. The first map based on actual field measurements was published in 1818 by the Czech mapmaker Franz Wilhelm Sieber. The first map based on modern surveying techniques was published by Charles Wilson of the Palestine Exploration Fund in 1864–65, who produced two maps for the British Ordnance Survey.

Effects of Extracellular Polymeric Substances on Sludge Properties
Extracellular polymeric substances (EPS) represent the complex high-molecular-weight mixture of polymers excreted by microorganisms generated from cell lysis as well as adsorbed inorganic and organic matter from wastewater. EPS exhibit a three-dimensional, gel-like, highly hydrated matrix that facilitates microbial attachment, embedding, and immobilization. EPS play multiple roles in containments removal, and the main components of EPS crucially influence the properties of microbial aggregates, such as adsorption ability, stability, and formation capacity. Moreover, EPS are important to sludge bioflocculation, settleability, and dewatering properties and could be used as carbon and energy sources in wastewater treatment.
