Bank Stabilization Structures of Yangtze-River
Bank Stabilization Structures of Yangtze-River are ecological revetment structures that have been carried out in the Yangtze River with a focus on preventing bed-shape evolution, river-width adjustment, and lateral channel migration, which are woody planting and combined applications of planting and artificial structures. The most widely used in the middle and lower reaches of the Yangtze River are steel wire mesh gabions bank stabilization and chain-type bricks bank stabilization.

Elastic Modulus
Elastic modulus (E) is a key parameter in predicting the ability of a material to withstand pressure and plays a critical role in the design of rock engineering projects. E has broad applications in the stability of structures in mining, petroleum, geotechnical engineering, etc. E can be determined directly by conducting laboratory tests, which are time consuming, and require high-quality core samples and costly modern instruments. Thus, devising an indirect estimation method of E has promising prospects.

Engineering Microbial Consortia towards Bioremediation
Engineering microbial consortia is an effective way for the removal of heavy metals and organic pollutants. In the study, we discussed the molecular and ecological mechanisms of engineering microbial consortia with a particular focus on metabolic cross-feeding within species and the transfer of metabolites. Besides, the advantages and limitations of top-down and bottom-up approaches of engineering microbial consortia were discussed, together with their applications in bioremediation.

MCDM Methods in Water Allocation
The water allocation problem is complex and requires a combination of regulations, policies, and mechanisms to support water management to minimize the risk of shortage among competing users. This study compiles the application of multi-criteria decision-making (MCDM) related to water allocation. In this regard, this paper aims to identify and to discern the pattern, distribution of study regions, water problem classifications, and decision techniques application for a specific water allocation problem. We applied a systematic literature review study from 2000 to 2019 by using four literature databases (Web of Science, Scopus, Science Direct, and Google Scholar). From 109 papers, 49 publications have been identified and information extracted. This study reveals that in the past two decades the application of MCDM in the area of water allocation has increased particularly after 2014. Around 65% and 12% of study papers were conducted in Asia and Europe, respectively. Water shortage, water use management, and water quality were consecutively the most top-ranked discussed water problems. NSGA II (non-dominated sorting genetic algorithm), GA (genetic algorithm), and LP (linear programming) are the more often applied decision methods to solve water allocation problems. The key findings of this study provide guidelines for future research studies.

Ciolo (Apulia)
Ciolo is a narrow coastal inlet and a site of historical and environmental interest, which is located in Apulia, Italy. The location is also known as a geological site and for the presence of numerous sea caves, the largest one being the Grotta del Ciolo. Since October 2006 the Ciolo's area has become part of the Regional Park "Costa Otranto - Santa Maria di Leuca e Bosco di Tricase", created by the Apulia region to protect the eastern coast of Salento, specifically the architectural assets as well as important animal and plant species. The name Ciolo comes from the noun in salentino dialect "ciole", which refers to crows or magpies, which are widespread in this region.

Main Raw Materials from Pineapple Biomass
Pineapple is a highly demanded fruit in international markets due to its unique appearance and flavor, high fiber content, vitamins, folic acid, and minerals. It makes pineapple production and processing a significant source of income for producing countries. The lignocellulosic biomass obtained from pineapple agro-industrial residues is mainly composed of cellulose, hemicellulose, and lignin; a compilation of information for these three compounds is presented below, with a specific focus on treatments and pretreatments that can be employed to obtain and purify them, as well as the most common applications of each.

Soil and Irrigation Water Salinity in Ethiopia
The salt problem in Ethiopia has been further exacerbated by a number of factors, including poor water quality, ineffective on-farm water management techniques, and a lack of appropriate and technically sound drainage infrastructure at irrigation sites.  Soil and irrigation water salinity have a substantial link with crops and agricultural communities in Ethiopia. Salinity has a significant impact on soil and water fertility, resulting in poorer agricultural production, food insecurity, and poverty. Salinity has a significant impact on crops in the country, from the germination stages to the harvesting stages during the growing season. If the current state of soil and water management continues, the severity of both soil and irrigation water salinity will reach an irreversible level that significantly impedes the country’s agricultural production capacity. As a result, cultured irrigation water treatment, crop selection based on salinity and sodicity levels, irrigation water quality, leaching, and fertilizer use in combination with organic manures are scientifically proven actions to address the salinity problem.

Karratha, Western Australia
Karratha is a city in the Pilbara region of Western Australia, adjoining the port of Dampier. It was established in 1968 to accommodate the processing and exportation workforce of the Hamersley Iron mining company and, in the 1980s, the petroleum and liquefied natural gas operations of the North West Shelf Venture. At June 2018, Karratha had an urban population of 16,708. The city's name comes from the cattle station of the same name, which derives from a word in a local Aboriginal language meaning "good country" or "soft earth". The city is the seat of government of the City of Karratha, a local government area covering the surrounding region.

The Great Global Warming Swindle
The Great Global Warming Swindle is a polemical documentary film that suggests that the scientific opinion on climate change is influenced by funding and political factors, and denies the existence of a scientific consensus about the reality and causes global warming. The program was formally criticised by Ofcom, the UK broadcasting regulatory agency, which upheld complaints of misrepresentation made by David King. The film, made by British television producer Martin Durkin, presents scientists, economists, politicians, writers, and others who dispute the scientific consensus regarding anthropogenic global warming. The programme's publicity materials assert that man-made global warming is "a lie" and "the biggest scam of modern times." Its original working title was "Apocalypse my arse", but the title The Great Global Warming Swindle was later adopted as an allusion to the 1980 mockumentary The Great Rock 'n' Roll Swindle about British punk band the Sex Pistols. The UK's Channel 4 premiered the documentary on 8 March 2007. The channel described the film as "a polemic that drew together the well-documented views of a number of respected scientists to reach the same conclusions. This is a controversial film but we feel that it is important that all sides of the debate are aired." According to Hamish Mykura, Channel 4's head of documentaries, the film was commissioned "to present the viewpoint of the small minority of scientists who do not believe global warming is caused by anthropogenic production of carbon dioxide." Although the documentary was welcomed by global warming deniers, it was criticised by scientific organisations and individual scientists (including one of the scientists interviewed in the film and one whose research was used to support the film's claims). The film's critics argued that it had misused and fabricated data, relied on out-of-date research, employed misleading arguments, and misrepresented the position of the Intergovernmental Panel on Climate Change. Later broadcasts corrected three errors in the original film.
