Sustainable Business Models
Over the years, researchers have presented different concepts regarding business models. There is no unanimity, but there is a general agreement that a business model is the representation of how a company conducts its business. Subsequently, interest in the topic has increased and has come to be considered by companies that, driven to incorporate a positive contribution to sustainability into their values, began to face economic development that considers social and environmental aspects instead of worrying only about profit for the shareholders.

Physiological Effects of Marijuana
To understand the impact of marijuana on the cardiovascular system, it is imperative to understand the endocannabinoid system. The endocannabinoid system (ECS) is comprised of the endocannabinoids anandamide and 2-arachidonylglycerol (both of which are endogenous lipid mediators), their metabolic enzymes, and G-protein coupled cannabinoid receptor 1 (CB1R) plus G-protein coupled cannabinoid receptor 2 (CB2R) [24]. CB1R is the primary receptor that mediates the effects of marijuana. CB1R is present in the brain, heart, vascular smooth muscle, and peripheral nervous system [6]. Its extensive presence in the human body makes its activation wide-reaching and impacts multiple systems.

Cigarette Lighter Receptacle
The cigarette lighter receptacle (also called a cigar lighter receptacle or cigar lighter socket) in an automobile was initially designed to power an electrically heated cigarette lighter, but became a de facto standard DC connector to supply electrical power for portable accessories used in or near an automobile. While the cigarette lighter receptacle is a common feature of automobiles and trucks, as a DC power connector it has the disadvantages of bulkiness, relatively low current rating, and poor contact reliability. Examples of devices that can be operated from a cigarette lighter receptacle include lights, fans, beverage heating devices, and small motorized tools such as air compressors for inflating tires. Many portable electronic devices such as music players or mobile telephones use a cigarette lighter receptacle to recharge their internal batteries or to directly operate from the vehicle electrical system. Adapters for electronic devices may change voltage to be compatible with the supplied device. Devices that require alternating-current mains electricity can be operated with a plug-in inverter. Automobiles may provide several 12 V receptacles that are intended only to operate electrical accessories, and which cannot be used with a cigarette lighter. Car manufacturers may offer a cigarette lighter only as an optional extra-cost accessory. Usually, only one 12 V receptacle near the driver will be able to accommodate an actual cigarette lighter, with other receptacles designated as "12 V auxiliary power outlets" which are not physically able to power a lighter.

Palm Kernel Cake for Poultry
Palm kernel cake (PKC), a by-product of oil extracted from palm nuts through expeller press or solvent extraction procedures is one of the highest quantities of locally available and potentially inexpensive agricultural products. PKC provides approximately 14–18% of crude protein (CP), 12–20% crude fiber (CF), 3–9% ether extract (EE), and different amounts of various minerals that feasible to be used as a partial substitute of soybean meal (SBM) and corn in poultry nutrition. Poultry’s digestibility is reported to be compromised due to the indigestion of the high fiber content, making PKC potentially low for poultry feeding. Nevertheless, solid-state fermentation (SSF) can be applied to improve the nutritional quality of PKC by improving the CP and reducing CF content. PKC also contains β-mannan polysaccharide, which works as a prebiotic.

Rotary-Percussion Drilling
The rotary-percussion drilling method is a prospective way to decrease drilling costs. It is obvious, based on literature analyses and finished geothermal drilling, that the Lublin Basin can be perceived as the one where rotary-percussion drilling can be used to drill an overburden of shale rocks. The paper explained the geology of the Lublin Basin, its’ geological structures, and the possibility of the use of drilling with a down-the-hole hammer, which could significantly decrease the cost of the whole shale gas drilling investment. Data collected from the wells drilled in the Lublin Basin were compared and analyzed to determine the viability of rotary-percussion drilling. Provided analyses showed that using the rotary-percussion drilling method in the Lublin Basin had a greater possibility of application than in other Polish shale basins (Baltic and Podlasie).

Renewable Energy Resources in Nigeria
Renewable energy resource utilisation is becoming more prevalent in society and can be a sustainable method to meet rising energy demand and consumption. The International Renewable Energy Agency reports that presently, approximately 33% of total electricity output around the world is from renewable energy sources. In Nigeria, the World Bank reported this figure as 18.2% in 2015. It is important to understand how Nigeria can raise this average as the world moves towards less use of fossil fuels.

Cultural Construction: A Fundamental Principle of Anthropology
A cultural construction can be defined as a set of ideas that shape the perception and understanding of a situation in a particular way, within a specific space-time context. The concept of cultural construction aims to describe a situation as a process and to make clear that this situation can be seen differently by each culture. Almost everything that has not been created by nature but by societies is a cultural construct (for example law, marriage, fashion, guilt, sex, etc.). This term was firstly presented in the European literature by Prof. Alexandros Argyriadis in 2014, in order to enrich the term "social construct". The significance of this term focuses mainly on the fact that it explains that every population group that perceives specific characteristics which might differ from the majority is not superior or inferior to another, but simply different.  It is important to note that the difference between social and cultural construction lies mainly in the fact that the cultural approach examines phenomena and processes always in their historical depth. Furthermore, it studies the deeper structures that lead to the emergence of a phenomenon considering that culture is the unconscious determinant of behaviors. At the same time, it focuses on art, experiences and everyday life, examining them as processes.

God in Catholicism
God in Catholicism is the God of Abraham, Isaac, and Jacob. The Catholic Church believes that there is one true and living God, the Creator and Lord of Heaven and Earth. Despite other opinions, God is All-Perfect; this infinite Perfection is viewed, successively, under various aspects, each of which is treated as a separate perfection and characteristic inherent to the Divine Substance, or Essence. A certain group of these, of paramount import, is called the Divine Attributes. The position of the Catholic Church declared in the Fourth Lateran Council (1215), is again stated in the following pronouncement of the Vatican Council: "The Holy, Catholic, Apostolic, Roman Church believes and confesses that there is one, true, living God, Creator and Lord of heaven and earth, omnipotent, eternal, immense, incomprehensible, infinite in intellect and will, and in every perfection; who, although He is one, singular, altogether simple and unchangeable spiritual substance, must be proclaimed distinct in reality and essence from the world; most blessed in Himself and of Himself, and ineffably most high above all things which are or can be conceived outside Himself."

Wiktionary
Wiktionary is a multilingual, web-based project to create a free content dictionary of all words in all languages. It is collaboratively edited via a wiki, and its name is a portmanteau of the words wiki and dictionary. It is available in 171 languages and in Simple English. Like its sister project Wikipedia, Wiktionary is run by the Wikimedia Foundation, and is written collaboratively by volunteers, dubbed "Wiktionarians". Its wiki software, MediaWiki, allows almost anyone with access to the website to create and edit entries. Because Wiktionary is not limited by print space considerations, most of Wiktionary's language editions provide definitions and translations of words from many languages, and some editions offer additional information typically found in thesauri and lexicons. The English Wiktionary includes a thesaurus (formerly known as Wikisaurus) of synonyms of various words. Wiktionary data are frequently used in various natural language processing tasks.
