Alkaline–Surfactant–Polymer Flooding Mechanisms
Chemical flooding, expecially  alkali–surfactant–polymer (ASP) injection plays an important role in enhancing oil recovery under many synergetic mechanisms, in which there are four main mechanisms that have been widely used, including improving the mobility ratio between the heavy oil and the displacing phase, lowering the interfacial tension between oil and water (IFT), altering the rock wettability (oil-wet to water-wet) and emulsifying oil and water. Laboratory tests and pilot trials of ASP injection showed that the oil recovery of the emulsified system is 5% more than the cases where no emulsions existed.

Machine Learning in Healthcare Industry
Machine learning is a mechanism that enables machines to learn automatically without explicit programming. The main area of machine learning is to use advanced algorithms and statistical techniques to access the data and predict accuracy instead of a rule-based system. The dataset is a primary component of machine learning accuracy prediction. As a result, the data are more relevant and the prediction is more accurate. Machine learning has been used in different fields, such as finance, retail, and the healthcare industry. The rising use of machine learning in healthcare provides more opportunities for disease diagnosis and treatment. Machine learning has a great feature of continuous improvement for data accurate prediction and classification purposes for disease analysis.

Skywell Shape in Huizhou Traditional Architecture
The skywell is a typical feature of Huizhou architecture and an important space; thus, there is the saying that “all halls are wells” . In traditional Huizhou architecture, the skywell, as a transition space between the interior and exterior, not only has positive significance for the lighting and ventilation of the building interior but also contains a lot of traditional Huizhou culture. Huizhou is famous for Huizhou merchants, who do not lack money and pay more attention to the construction of their own houses and the comfort and beauty of their houses; they set up skywells in their houses to acquire the aura of the “unity of heaven and man” and the pride of “standing on top of the sky”. On sunny days, the sun shines through the skywell to the front of the hall and the rooms, which means “sprinkling gold”; in rainy and snowy weather, rainwater flows down from the eaves around the skywell and sinks into the tank below the skywell, which means “flowing silver” and is a metaphor for wealth, also known as the “four waters to the hall”. In the skywell, combined with the through corridors and open halls, when the outdoor wind speed is high, wind pressure ventilation makes up the majority of the wind entering into the room from the skywell out, reducing the amount of indoor ventilation. When the outdoor wind is still, the skywell-shaped thermal pressure, which promotes indoor and outdoor ventilation, thus forms a complete ventilation system and plays the role of “hiding wind and gathering air”.

Fintech and Sustainability
Current concerns about environmental issues have led to many new trends in technology and financial management. Within this context of digital transformation and sustainable finance, Fintech has emerged as an alternative to traditional financial institutions. This paper, through a literature review and case study approach, analyzes the relationship between Fintech and sustainability, and the different areas of collaboration between Fintech and sustainable finance, from both a theoretical and descriptive perspective, while giving specific examples of current technological platforms. Additionally, in this paper, two Fintech initiatives (Clarity AI and Pensumo) are described, as well as several proposals to improve the detection of greenwashing and other deceptive behavior by firms. The results lead to the conclusion that sustainable finance and Fintech have many aspects in common, and that Fintech can make financial businesses more sustainable overall by promoting green finance. Furthermore, this paper highlights the importance of European and global regulation, mainly from the perspective of consumer protection.

NEC Engineering and Construction Contract
The New Engineering Contract (NEC), or NEC Engineering and Construction Contract, is a formalised system created by the UK Institution of Civil Engineers that guides the drafting of documents on civil engineering and construction projects for the purpose of obtaining tenders, awarding and administering contracts. As such they legally define the responsibilities and duties of Employers (who commission work) and Contractors (who carry out work) in the Works Information. The contract consists of two key parts the Contract Data part one (Data provided by the Employer) and Contract Data part two (Data provided by the Contractor). Several approaches are included making it a family of options. It is used in the UK and internationally in countries including New Zealand, Australia , Hong Kong and South Africa . There have been four editions, the first in 1993, the second in 1995, the third in 2005 and the most recent in 2017. The NEC3 was launched in 2005 and it was amended in April 2013. NEC4 was announced in March 2017 and has been available since June 2017. This new edition reflects procurement and project management developments and emerging best practice, with improvements in flexibility, clarity and the ease of administration. It also introduces two new contracts: NEC4 Design, Build and Operate (DBO) and NEC4 Alliance Contract (ALC).

September 2019 Climate Strikes
The September 2019 climate strikes, also known as the Global Week for Future, were a series of international strikes and protests to demand action be taken to address climate change, which took place from 20–27 September. The strikes' key dates were 20 September, which was three days before the United Nations Climate Summit, and 27 September. The protests took place across 4,500 locations in 150 countries. The event is a part of the school strike for climate movement, inspired by Swedish climate activist Greta Thunberg. The Guardian reported that roughly 6 million people participated in the events, whilst 350.org—a group that organised many of the protests—claim that 7.6 million people participated. The 20 September protests were likely the largest climate strikes in world history. Organisers reported that over 4 million people participated in strikes worldwide, including 1.4 million participants in Germany. An estimated 300,000 protesters took part in Australian strikes, a further 300,000 people joined UK protests and protesters in New York—where Greta Thunberg delivered a speech—numbered roughly 250,000. More than 2,000 scientists in 40 countries pledged to support the strikes. A second wave of protests took place on 27 September, in which an estimated 2 million people took part in over 2,400 protests. There were reported figures of one million protesters in Italy, and 170,000 people in New Zealand. In Montreal, where Greta Thunberg spoke, the Montreal school board cancelled classes for 114,000 of its students. Hundreds of thousands of people, including several federal party leaders, joined the march in Montreal.

Bioremediation of Heavy Metals by Microorganisms
Heavy metal pollution is a major environmental problem because metal ions persist in the environment due to their non-degradable nature. The toxicity and bioaccumulation tendency of heavy metals in the environment is a serious threat to the health of living organisms. Unlike organic contaminants, chemical or biological processes cannot break down heavy metals. Hence, they can only be transformed into less toxic species.

Torsion-Resistant Nature-Inspired Structures
The complexity of torsional load, its three-dimensional nature, its combination with other stresses, and its disruptive impact make torsional failure prevention an ambitious goal. However, even if the problem has been addressed for decades, a deep and organized treatment is still lacking in the actual research landscape. For this reason, this review aims at presenting a methodical approach to address torsional issues starting from a punctual problem definition. Accidents and breaks due to torsion, which often occur in different engineering fields such as mechanical, biomedical, and civil industry are considered and critically compared. More in depth, the limitations of common-designed torsion-resistant structures (i.e., high complexity and increased weight) are highlighted, and emerge as a crucial point for a deeper nature-driven analysis of novel solutions. In this context, an accurate screening of torsion-resistant bio-inspired unit cells is presented, taking inspiration specifically from plants, that are often subjected to the torsional effect of winds. As future insights, the actual state of technology suggests an innovative transposition to the industry: these unit cells could be prominently implied to develop novel metamaterials that could be able to address the torsional issue with a multi-scale and tailored arrangement.

Waka (Canoe)
Waka (Māori: [ˈwaka]) are Māori watercraft, usually canoes ranging in size from small, unornamented canoes (waka tīwai) used for fishing and river travel to large, decorated war canoes (waka taua) up to 40 metres (130 ft) long. The earliest remains of a canoe in New Zealand were found near the Anaweka estuary in a remote part of the Tasman District and radiocarbon-dated to about 1400. The canoe was constructed in New Zealand, but was a sophisticated canoe, compatible with the style of other Polynesian voyaging canoes at that time. Since the 1970s about eight large double-hulled canoes of about 20 metres have been constructed for oceanic voyaging to other parts of the Pacific. They are made of a blend of modern and traditional materials, incorporating features from ancient Melanesia, as well as Polynesia.

Essential Oils and Neurodegenerative Diseases
Despite the improvements in life expectancy, neurodegenerative conditions have arguably become the most dreaded maladies of older people. The neuroprotective and anti-ageing potentials of essential oils (EOs) are widely evaluated around the globe. The entry focuses on analysing the effectiveness of EOs as neuroprotective remedies among the four common age-related neurodegenerative diseases. The literature was extracted from three databases (PubMed, Web of Science and Google Scholar) between the years of 2010 to 2020 using the medical subject heading (MeSH) terms “essential oil”, crossed with “Alzheimer’s disease (AD)”, “Huntington’s disease (HD)”, “Parkinson’s disease (PD)” or “amyotrophic lateral sclerosis (ALS)”. Eighty three percent (83%) of the studies were focused on AD, while another 12% focused on PD. No classifiable study was recorded on HD or ALS. EO from Salvia officinalis has been recorded as one of the most effective acetylcholinesterase and butyrylcholinesterase inhibitors. However, only Cinnamomum sp. has been assessed for its effectiveness in both AD and PD.

Public School Choice Options in the United States
Under the structure of compulsory education, students in the United States are required to attend school until at least 16 years of age, which can be done at a variety of educational institutions, both public and private. Amongst public schools, students are each assigned a neighborhood school but also frequently have the option to attend a choice school. While the purpose of neighborhood schools is to provide a guaranteed educational option that accommodates most students, choice schools serve varied purposes that accommodate specific learning styles and societal goals. Four types of publicly funded choice schools are magnet, charter, alternative, and virtual schools. While each was established to serve a specific societal goal, their purposes have shifted over time and have produced varied student outcomes, both academic and non-academic.
