Slow Sand Filtration for Raw Water Treatment
Filtration methods are traditional techniques of water purification used by mankind since ancient times. By filtering, water can be cleaned of sand, silt, turbidity, scale, and other suspended particles. Modern slow sand filters (SSFs) for water purification were first used in the 19th century in England. Therefore, they are often called English filters. The first slow filter was built by the English engineer James Simpson in 1829 in London to purify water from the river Thames.

Circumscribed Circle
In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius. Not every polygon has a circumscribed circle. A polygon that does have one is called a cyclic polygon, or sometimes a concyclic polygon because its vertices are concyclic. All triangles, all regular simple polygons, all rectangles, all isosceles trapezoids, and all right kites are cyclic. A related notion is the one of a minimum bounding circle, which is the smallest circle that completely contains the polygon within it, if the circle's center is within the polygon. Every polygon has a unique minimum bounding circle, which may be constructed by a linear time algorithm. Even if a polygon has a circumscribed circle, it may be different from its minimum bounding circle. For example, for an obtuse triangle, the minimum bounding circle has the longest side as diameter and does not pass through the opposite vertex.

Bodybuilding and Myostatin
MSTN is a gene that makes instructions for producing the protein myostatin, a protein that is part of the transforming growth factor beta family (TGFβ). The TGFβ family of proteins control the growth of tissues in the body, myostatin is found nearly exclusively in the skeletal muscles where it is active before and after birth. The protein actually controls skeletal growth by restraining it, preventing muscles becoming excessively large. Current research that surrounds myostatin is based around its potential treatment in muscle wasting disorders, animals that have mutations in the encoding gene MSTN show greater muscle mass, strength and in some circumstances reduced bodyfat, which can be known as myostatin-related muscle hypertrophy. This study aimed to see the prevalence of mutations in the male bodybuilder population (n = 92) and if having a mutation had any affect on their muscle size and/or muscle performance. The study which looked at mutation prevalence in rs1805086, arm circumference, pull-up max and push-up max. The results show that 17% (16) of the subject group had one mutation (AG), 83% (76) had the common outcome (AA) and 0% (0) had two mutations (GG). Those with the AG outcome had an average arm circumference of 46.37cmcompared with AA which had an average of 42.02cm. Those with the AG outcome had an average pull-up max score of 21 compared with AA with an average of 12. Those with the AG outcome had an average push-up max of 61 compared with AA with an average of 40. The study clearly shows that those with a mutation are rare, however the mutation does appear to give the subject a performance and size advantage over those with the common outcome.

Bonded Marine Hoses for Floating Offshore Structures (FOS)
By characterisation, a marine hose is a unique type of flexible riser used in fluid transfer. By definition, a marine hose is simply a fluid transfer conduit utilised in transferring, discharging, loading, and transporting fluids from an oil well to the platform of a floating platform or a floating structure. The fluid transfer system for bonded marine hoses is dependent on floating offshore structures (FOS). Single Point Mooring (SPM) systems are component aspects of the techno-economic design and FOS operation.

Brahmacarya
Brahmacharya (/ˌbrɑːməˈtʃɑːrjə/; Devanagari: ब्रह्मचर्य, Bengali: ব্রহ্মচর্য odia:ବ୍ରହ୍ମଚର୍ଯ୍ୟ lit."pure conduct") is a concept within Indian religions that literally means to stay in conduct within one's own Self. In Yoga, Hinduism and Jainism it generally refers to a lifestyle characterized by sexual continence or complete abstinence. Brahmacharya is somewhat different from the English term "celibacy," which merely means non-indulgence in sexual activity. Brahmacharya is when a person completely controls his body and mind (citta) through ascetic means. In the Hindu, Jain, and Buddhist monastic traditions, brahmacharya implies, among other things, the mandatory renunciation of sex and marriage. It is considered necessary for a monk's spiritual practice. Western notions of the religious life as practiced in monastic settings mirror these characteristics.

Positive Stereotype
In social psychology, a positive stereotype refers to a subjectively favorable belief held about a social group. Common examples of positive stereotypes are Asians with better math ability, African Americans with greater athletic ability, and women with being more warm and communal. As opposed to negative stereotypes, positive stereotypes represent a "positive" evaluation of a group that typically signals an advantage over another group. As such, positive stereotypes may be considered a form of compliment or praise. However, positive stereotypes can have a positive or negative effect on targets of positive stereotypes. The positive or negative influence of positive stereotypes on targets depends on three factors: (1) how the positive stereotype is stated, (2) who is stating the positive stereotype, (3) in what culture the positive stereotype is presented (e.g., Western contexts vs. East Asian contexts).

Megafaunal Wolf
The megafaunal wolf (Canis cf. lupus) was a Late Pleistocene – early Holocene hypercarnivore similar in size to a large extant gray wolf. It had a shorter, broader palate with large carnassial teeth relative to its overall skull size. This adaptation allowed it to prey and scavenge on Pleistocene megafauna. Such an adaptation is an example of phenotypic plasticity. It was once distributed across the northern Holarctic.

Impact Factor
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly average number of citations of articles published in the last two years in a given journal. It is frequently used as a proxy for the relative importance of a journal within its field; journals with higher impact factor values are often deemed to be more important, or carry more intrinsic prestige in their respective fields, than those with lower values.

Business Environment and Competitive Advantages
       Tourism destination competitiveness reflecting the generic characteristics should be considered diversified to notice the distinctive perspective between the business environment and competitive advantages. Criticism of some prior conventional literature stems from the lack of a rigorous process to find the structure and attributes of the measurement items for a destination’s business environment and competitive advantages. The available theoretical framework and measures containing the destination business environment and competitive advantages warrant further investigation. The vital dimensions of the destination business environment (i.e., dynamism,hostility,turbulence,investment,information technology,and governance) and destination competitive advantages (i.e., defensiveness, local acceptance, accessibility, reasonability, uniqueness, supportiveness, and image sustainability) were successfully identified through quantitative and empirical analysis, which could provide a significant basis for managerial and policy decisions in the tourism industry.

Luxury Vehicle
A luxury vehicle provides increased levels of comfort, equipment, amenities, quality, performance, and status relative to regular cars for an increased price. The term is subjective and reflects both the qualities of the car and the brand image of its manufacturer. Luxury brands rank above premium brands, though there is no fixed demarcation between the two. Traditionally, most luxury cars were large vehicles, though smaller sports-oriented models were always produced. “Compact“ luxury vehicles such as hatchbacks, and off-road capable sport utility vehicles, are relatively modern trends.

Windows NT
Windows NT is a proprietary graphical operating system produced by Microsoft, the first version of which was released on July 27, 1993. It is a processor-independent, multiprocessing and multi-user operating system. The first version of Windows NT was Windows NT 3.1 and was produced for workstations and server computers. It was a commercially focused operating system intended to complement consumer versions of Windows that were based on MS-DOS (including Windows 1.0 through Windows 3.1x). Gradually, the Windows NT family was expanded into Microsoft's general-purpose operating system product line for all personal computers, deprecating the Windows 9x family. "NT" was formerly expanded to "New Technology" but no longer carries any specific meaning. Starting with Windows 2000, "NT" was removed from the product name and is only included in the product version string along with several low-level places within the system. NT was the first purely 32-bit version of Windows, whereas its consumer-oriented counterparts, Windows 3.1x and Windows 9x, were 16-bit/32-bit hybrids. It is a multi-architecture operating system. Initially, it supported several instruction set architectures, including IA-32, MIPS, and DEC Alpha; support for PowerPC, Itanium, x64, and ARM were added later. The latest versions support x86 (including IA-32 and x64) and ARM. Major features of the Windows NT family include Windows Shell, Windows API, Native API, Active Directory, Group Policy, Hardware Abstraction Layer, NTFS, BitLocker, Windows Store, Windows Update, and Hyper-V.
