Catholic Teachings on Heresy
In the Roman Catholic Church, heresy has a very specific meaning. There are four elements which constitute formal heresy; a valid Christian baptism; a profession of still being a Christian; outright denial or positive doubt regarding a truth that the Catholic Church regards as revealed by God; and lastly, the disbelief must be morally culpable, that is, there must be a refusal to accept what is known to be a doctrinal imperative. Therefore, to become a heretic in the strict canonical sense and be excommunicated, one must deny or question a truth that is taught as the word of God, and at the same time recognize one's obligation to believe it. If the person is believed to have acted in good faith, as one might out of ignorance, then the heresy is only material and implies neither guilt nor sin against faith.

Fashion Influencer
A fashion influencer is a personality that has a large number of followers on social media, creates mainly fashion content and has the power to influence the opinion and purchase behavior of others with their recommendations. Brands endorse them to attend fashion shows, parties, designer dinners and exclusive trips and to wear their clothes on social media. If a salary has been involved, the influencer may be required to label such posts as paid or sponsored content. Before social media "they would have been called 'It girls'". Business magazine Forbes identified fashion influencers as "the new celebrity endorsements". However, influencers seem to have a closer relationship with their audience than traditional celebrities. As marketers Jung von Matt, Brandnew IO and Facelift point out: "Daily interactions across multiple channels, through photos, stories or live sessions, create a form of closeness and trust" that make influencers "often more tangible than traditional celebrities".

Haze in Beer
Beer is one of the oldest and also most widely consumed alcoholic beverages. It is a kind of colloid solution with complex composition and weak stability. The haze formation in beer is a serious quality problem, as it primarily affects the shelf life and flavor of beer. Hazes are caused by suspended insoluble particles of colloidal or larger size that can be perceived visually or by instruments.

Manual Muscle Testing for Post-Stroke Upper Extremity Assessment
The Manual Muscle Testing (MMT) scoring system is an assessment tool used by rehabilitation physicians or physiatrists, physiotherapists, neurologists, and other clinicians who deal with the individuals’ functional status. The most frequently used approach is the use of MMT to assess the grade of muscle weakness in different pathologies.

Fucoxanthin Extracted from Brown Algae
The scientific community has corroborated the numerous beneficial activities of fucoxanthin, such as its antioxidant, anti-inflammatory, anticancer or neuroprotective effects, among others. These properties have attracted the attention of nutraceutical, cosmetic and pharmacological industries, giving rise to various possible applications. Fucoxanthin may be chemically produced, but the extraction from natural sources is considered more cost-effective, efficient and eco-friendly. Thus, identifying suitable sources of this compound and giving a general overview of efficient extraction, quantification, purification and stabilization studies is of great importance for the future production and commercialization of fucoxanthin. The entry describes the potential applications of fucoxanthin pigment. Its production must face several challenges since its chemical synthesis represents a complex process which is not efficient and the extraction method from marine organisms has been not standardized. The main characteristic of a profitable product is to be obtained by using simple, fast, and based on low-cost technologies. This work provides an overview of different extraction conditions that may help in the standardization of the process, especially important at an industrial level. Therefore, the main aim of this work has been to underline the best algae species in terms of fucoxanthin production and the most promising extraction and purification methods, while offering a complete panorama of the described bioactivities of fucoxanthin which includes bioavailability, administration via, doses and stability of the molecule under different conditions.

Cost-Effective Water Purification Method
Water scarcity is occurring due to the rapid increase in the global population, intense industrialization, stringent water quality standards, and negative climate change. Contamination with heavy metals (arsenic, iron, lead, mercury, chromium), microbes (Escherichia coli, Staphylococus), biological compounds, and other components (fluoride, cadmium) is widely encountered. Carbon based materials, including activated carbon, MWCNT. graphene, r-graphene, cabon dot and fullerene provides cost effective option for water purification. The specific surface area, strong sorption, fast kinetics and like, are properties of these carbon based materials responsible potential water treatment application.

Tourism-phobia
The perception of residents of tourist areas affected by intensification of tourism or overtourism, has changed from a positive or neutral vision to overt annoyance or irritation, which has generated a certain debate that has been conveyed in the media, an innovative aspect in the field of tourism. The term tourism phobia is mentioned for the first time in Spain linked to problems related to tourism and tourists. Donaire (Romero et al., 2019) specifically mentions the term tourism-phobia, referring to discontent in the latter stages in the Doxey's model (1975). Huete and Mantecón (2018) and Milano (2017, 2018) have linked tourism-phobia with a certain social opposition and criticism of tourist management. Milano (2018) describes that social criticism within a context of social organizations and residents outlining their disagreement with certain tourist activities. Huete and Mantecón (2018) coincides with Milano by pointing out that what the media considers to be tourism-phobia is essentially a social critique of certain aspects of tourism. Other authors (Alcalde et al., 2018) highlight that the concept of tourism- phobia has been used in a misguided way, confusing the social discontent due to too many tourists with the rejection of them. Simultaneously and as opposed to the concept of tourism-phobia, the term tourism-philia arises, which refers to the perception of the positive effects of tourism on the local economy and society (Zerva et al., 2019).

Space Travel Using Constant Acceleration
Constant acceleration is a proposed aspect of most future forms of space travel. It entails that the propulsion system of whatever kind operate continuously with a steady acceleration, rather than the brief impulsive thrusts used by chemical rockets — for the first half of the journey it constantly pushes the spacecraft towards its destination, and for the last half of the journey it constantly uses backthrust, so that the spaceship arrives at the destination at a standstill.
