Drilling Fluids for Extended-Reach Wells
In the planning phase of extended-reach well (ERW), special attention should be paid to the choice of drilling fluid. Selected drilling fluids for extended-reach wells should satisfy the same basic functions that are common to all drilling fluids, and they have to provide excellent reservoir protection. When drilling extended-reach wells, the following critical factors should be considered: hole cleaning, torque and drag, borehole stability, equivalent circulating density (ECD) and lost circulation. So far, oil-based mud (OBM) and water-based mud (WBM) have also been used in practice, but the emphasis is on the application of environmentally friendly additives.

Licorice and the Cardiovascular System
Licorice is one of the oldest used herbs for medicinal purposes and consists of up to 300 active compounds. The main active constituent of licorice is the prodrug glycyrrhizin, which is successively converted to 3β-monoglucuronyl-18β-glycyrrhetinic acid (3MGA) and 18β-glycyrrhetinic acid (GA) in the intestines. Despite many reported health benefits, 3MGA and GA inhibit the 11-β-hydrogenase type II enzyme (11β-HSD2) oxidizing cortisol to cortisone. Through activation of mineralocorticoid receptors, high cortisol levels induce a mild form of apparent mineralocorticoid excess in the kidney and increase systemic vascular resistance. Continuous inhibition of 11β-HSD2 related to excess licorice consumption will create a state of hypernatremia, hypokalemia and increased fluid volume.

Computer Reservation System
A computer reservation system or central reservation system (CRS) is a computerized system used to store and retrieve information and conduct transactions related to air travel, hotels, car rental, or other activities. Originally designed and operated by airlines, CRSs were later extended for the use of travel agencies. Global distribution systems (GDS) book and sell tickets for multiple airlines. Most airlines have outsourced their CRSs to GDS companies, which also enable consumer access through Internet gateways. Modern GDS's typically allow users to book hotel rooms, rental cars, airline tickets as well as other activities and tours. They also provide access to railway reservations and bus reservations in some markets, although these are not always integrated with the main system. These are also used to relay computerized information for users in the hotel industry, making reservation and ensuring that the hotel is not overbooked. Airline reservations systems may be integrated into a larger passenger service system, which also includes an airline inventory system and a departure control system.

Monoculture
Monoculture is the agricultural practice of producing or growing a single crop, plant, or livestock species, variety, or breed in a field or farming system at a time. Polyculture, where more than one crop is grown in the same space at the same time, is the alternative to monoculture. Monoculture is widely used in both industrial farming and organic farming and has allowed increased efficiency in planting and harvest. Continuous monoculture, or monocropping, where the same species is grown year after year, can lead to the quicker buildup of pests and diseases, and then rapid spread where a uniform crop is susceptible to a pathogen. The practice has been criticized for its environmental effects and for putting the food supply chain at risk. Diversity can be added both in time, as with a crop rotation or sequence, or in space, with a polyculture. Oligoculture has been suggested to describe a crop rotation of just a few crops, as is practiced by several regions of the world. The term monoculture is frequently applied for other uses to describe any group dominated by a single variety, e.g. social monoculturalism, or in the field of musicology to describe the dominance of the American and British music-industries in Western pop music, or in the field of computer science to describe a group of computers all running identical software.

Consumer–Brand Congruence and Consumer-Celebrity Congruence
The consumer–celebrity congruence moderated the indirect effect of consumer–brand congruence on brand preference and boycott recommendations, but not purchase intention. When brands practice CSA, consumer–brand congruence rather than consumer–celebrity congruence could play a more important role in shaping consumer behaviors.

Bump Fire
Bump fire is the act of using the recoil of a semi-automatic firearm to fire shots in rapid succession, which simulates the rate of fire of a fully automatic firearm. Bump fire gunstocks are of varying legality in the United States. The Department of Justice announced a plan on March 23, 2018 to classify bump stocks as "machine guns" and effectively ban them nationwide under existing federal law. If the rule becomes final, existing bump stocks would be required to be destroyed or surrendered by both manufacturers and individual owners. On April 17, 2018, Slide Fire Solutions, the sole holder of the bump stock patent, announced that it would cease production of bump stocks as of May 20, though they did not state whether this was a temporary or permanent measure. It has temporarily suspended production before.

Skin Tissue Engineering Application
Skin tissue engineering has made remarkable progress in wound healing treatment with the advent of newer fabrication strategies using natural/synthetic polymers and stem cells. Currently, stem cells and biomaterials are popularly used in the skin tissue engineering approach in different wound healing treatments. In skin tissue engineering application, stem cell facilitates in the regeneration of disintegrated tissue. Whereas, biomaterials serve as a platform to improve the engraftment of implanted cells and facilitate the function of exogenous cells by mimicking the tissue microenvironment. Hence, the combination and synergistic effect of biomaterials and stem cells have the potential to broaden the application of skin tissue engineering in wound healing treatment therapies.

The city is located at the heart of the lower valley of Büyük Menderes River (ancient Meander River) at a commanding position for the region extending from the uplands of the valley down to the seacoast. Its population was 207,554 in 2014. Aydın city is located along a region which was famous for its fertility and productivity since ancient times. Figs remain the province's best-known crop, although other agricultural products are also grown intensively and the city has some light industry. At the crossroads of a busy transport network of several types, a six-lane motorway connects Aydın to İzmir, Turkey's second port, in less than an hour, and in still less time to the international Adnan Menderes Airport, located along the road between the two cities. A smaller airport, namely Aydın Airport, is located a few kilometers in the South-East of Aydın. The region of Aydın also pioneered the introduction of railways into Turkey in the 19th century and still has the densest railroad network. The province of Aydın is also where a number of internationally known historic sites and centers of tourism are concentrated.
