Coal Fly Ash Use in Cement and Concrete
Nowadays, coal is increasingly being used as an energy source in some countries. This coal-fired generation process, however, has the disadvantage that produces large quantities of coal fly ash. Its characteristics differ depending on the combustion conditions and the coal source. Fineness will influence early compressive strength in cement-based materials. The finer the binding material, the higher the early compressive strength. They can be used to produce high-volume fly ash (HVFA) concrete, self-compacting concrete (SCC), concrete for marine infrastructures, pervious concrete, roller compacted concrete (RCC) and so on.

Detecting Lithium Mineralizations from Space
Optical and thermal remote sensing data have been an important tool in geological exploration for certain deposit types. However, the present economic and technological advances demand the adaptation of the remote sensing data and image processing techniques to the exploration of other raw materials like lithium (Li). A review of the application studies and developments in this field was also made. The addressed topics include: (i) achievements made in Li exploration using remote sensing methods; (ii) the main weaknesses of the approaches; (iii) how to overcome these difficulties; and (iv) the expected research perspectives. We expect that the number of studies concerning this topic will increase in the near future and that remote sensing will become an integrated and fundamental tool in Li exploration.

Energy Crops
Energy crops are dedicated cultures directed for biofuels, electricity, and heat production. Due to their tolerance to contaminated lands, they can alleviate and remediate land pollution by the disposal of toxic elements and polymetallic agents. Moreover, these crops are suitable to be exploited in marginal soils (e.g., saline), and, therefore, the risk of land-use conflicts due to competition for food, feed, and fuel is reduced, contributing positively to economic growth, and bringing additional revenue to landowners.

Mangalore
Mangalore (/mæŋɡəˈlɔːr/), officially known as Mangaluru, is a major port city of the Indian state of Karnataka. It is located between the Arabian Sea and the Western Ghats about 352 km (219 mi) west of Bangalore, the state capital, 20 km north of Karnataka–Kerala border, 297 km south of Goa. Mangalore is the state's only city to have all four modes of transport—air, road, rail and sea. The population of the urban agglomeration was 619,664 (As of 2011) national census of India. It is known for being one of the locations of the Indian strategic petroleum reserves. The city developed as a port in the Arabian Sea during ancient times; it has since developed into a major port of India that handles 75 per cent of India's coffee and cashew exports, and is the country's seventh largest container port. Mangalore has been ruled by several major powers, including the Kadambas, Alupas, Vijayanagar Empire, Keladi Nayaks and the Portuguese. The city was a source of contention between the British and the Kingdom of Mysore rulers Hyder Ali and Tipu Sultan, and was eventually annexed by the British in 1799. Mangalore remained part of the Madras Presidency until India's independence in 1947 and was unified with Mysore State (now called Karnataka) in 1956. Mangalore is also the administrative headquarters of the Dakshina Kannada district, and is a commercial, industrial, educational, healthcare and startup hub. This city's International Airport is the second-largest and second-busiest airport in Karnataka. Mangalore City Corporation is responsible for the civic administration, which manages the 60 wards of the city. The city's landscape is characterised by rolling hills, coconut palms, rivers and hard laterite soil. India's first 3D planetarium with 8K resolution display is situated in this city. Mangalore is also included in the Smart Cities Mission list and is among the 100 smart cities to be developed in India. The city has an average elevation of 22 m (72 ft) above mean sea level. Mangalore has a tropical monsoon climate and is under the influence of the southwest monsoon. (As of 2017), Mangalore was ranked the 48th best city to live in the world by a US survey, and the only Indian city in the top 50.

Climate Change Denial
File:Former Senator Tom Coburn- Paris Climate Agreement Was 'Poorly Negotiated'.webm Climate change denial, or global warming denial is denial, dismissal, or unwarranted doubt that contradicts the scientific consensus on climate change, including the extent to which it is caused by humans, its effects on nature and human society, or the potential of adaptation to global warming by human actions. Many who deny, dismiss, or hold unwarranted doubt about the scientific consensus on anthropogenic global warming self-label as "climate change skeptics", which several scientists have noted is an inaccurate description. Climate change denial can also be implicit, when individuals or social groups accept the science but fail to come to terms with it or to translate their acceptance into action. Several social science studies have analyzed these positions as forms of denialism, pseudoscience, or propaganda. The campaign to undermine public trust in climate science has been described as a "denial machine" organized by industrial, political and ideological interests, and supported by conservative media and skeptical bloggers to manufacture uncertainty about global warming. The politics of global warming have been affected by climate change denial and the political global warming controversy, undermining the efforts to act on climate change or adapting to the warming climate. Those promoting denial commonly use rhetorical tactics to give the appearance of a scientific controversy where there is none. Organised campaigning to undermine public trust in climate science is associated with conservative economic policies and backed by industrial interests opposed to the regulation of CO2 emissions. Climate change denial has been associated with the fossil fuels lobby, the Koch brothers, industry advocates and conservative think tanks, often in the United States. More than 90% of papers sceptical on climate change originate from right-wing think tanks. Since the late 1970s, oil companies have published research broadly in line with the standard views on global warming. Despite this, oil companies organized a climate change denial campaign to disseminate public disinformation for several decades, a strategy that has been compared to the organized denial of the hazards of tobacco smoking by the tobacco industry.

Energy Use in Greenhouses in the EU
High energy systems, which are more dominant in northern Europe, are generally heavily climate controlled and energy use is dominated by heating and cooling processes, while low energy systems, which are dominant in southern Europe, show a mixture of energy uses including heating, cooling, irrigation, lighting, fertilisers, and pesticides.

Granular Organic Fertilizers
Granular organic fertilizers' production has recently become more popular, with the main aim of converting high-moisture organic matter, such as manure, manure mixtures, meat and bone waste or other organic matter, into pellets that are convenient to spread in the field. The pellets are usually produced with the diameter of 4 or 6 mm so that they can be easily spread with mineral or organic fertilizer spreaders. Once in the soil, organic fertilizer pellets become wet, decompose and release nutrients.

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.

Environmental Protection and Sustainable Development in Madagascar
Located on the East coast of Africa, Madagascar is the world’s fourth-biggest island; Madagascar is host to 12,000 species of vascular plants (96% endemic). Over 90% of all its wildlife is found nowhere else on earth, and 5% of all of the earth’s biodiversity is found in Madagascar. A place where environmental degradation problems have created severe erosion and water quality problems. Despite its biological and cultural diversity, Madagascar is among the poorest countries in the world, with approximately 78% of the population living in extreme poverty with an average income of less than USD 2 per day, and more than three-quarters of the population in rural areas engaged in natural resources dependent livelihood activities.
