Impacts of Brick Making on Environment
The brick making industry, despite its contribution to environmental pollution, plays a major role in the economic growth of many nations, with the traditional technology accounting for a significant proportion of the total clay brick production. This writeup gives an overview of the origin of brickmaking, its socioeconomic importance, the environmental impacts and improvements made in the art of brickmaking over the years. The environmental impacts from brickmaking cannot be overruled, however, this impacts could be minimized and managed  through the adoption of more sustainable and environmentally friendly firing innovative.

List of Devices with LTE Advanced
List of devices with LTE Advanced support. LTE is a standard for wireless communication and LTE Advanced (Cat 6 and above) is a high speed version of LTE, sometimes marketed as LTE+, 4G+, 4GX, 4.5G or 4G LTE Ultra. LTE support varies from country to country, and the speed may vary depending on user location and how fast they're travelling. The list below shows the devices that should support LTE Cat 6 and above.

The Transition to Adulthood
The transition to adulthood is a process that brings childhood to an end and turns the individual into a young adult. This process is characterised by the acquisition of new roles for young people, roles linked to the development of personal autonomy that culminate in their emotional and functional independence.

Fixed and Floating Offshore Structures
Diverse forms of offshore oil and gas structures are utilized for a wide range of purposes and in varying water depths. They are designed for unique environments and water depths around the world. The applications of these offshore structures require different activities for proper equipment selection, design of platform types, and drilling/production methods. There are advances made in ocean engineering which include a variety of innovative offshore structure designs, ranging from fixed platforms to floating platforms. Some of these structures include the deep-water semisubmersible platforms, jack-up rigs, floating offshore wind turbines (FOWTs), FPS (floating production systems) units.

Agricultural Production in Qatar
Starting in the 1970s, Qatar had almost entirely based its economic growth on resource exploitation of the hydrocarbon sector, with agriculture being considered only as a ‘’hobby’’, rather than an important economic activity. The real driver of change affecting Qatar’s agricultural sector is the issue of food security, after the 2017 embargo (imposed by neighboring countries that made Qatar’s government critically aware that it cannot rely on other countries to secure its food basket), and thus highlighted the need to produce in the country.The factor that has most hindered the development of productive agricultural and horticultural systems in the past has been the availability of land, with suitable soils. This is a consequence of Qatar’s harsh climate; it is in a hot arid zone characterized by sparse precipitation; high summer temperatures; together with high humidity in the late summer months that makes working outside very difficult; very high solar radiation; strong winds; and limited freshwater availability for irrigation causing dependency on desalinated abstracted groundwater, and/or (more recently) on desalinated sea-water.

Philistinism
In the fields of philosophy and æsthetics, the derogatory term philistinism describes “the manners, habits, and character, or mode of thinking of a philistine”, manifested as an anti-intellectual social attitude that undervalues and despises art and beauty, intellect and spirituality. A philistine person is a man or woman of smugly narrow mind and of conventional morality whose materialistic views and tastes indicate a lack of and an indifference to cultural and æsthetic values. Since the 19th century, the contemporary denotation of philistinism, as the behaviour of "ignorant, ill-behaved persons lacking in culture or artistic appreciation, and only concerned with materialistic values" derives from Matthew Arnold's adaptation to English of the German word Philister, as applied by university students in their antagonistic relations with the townspeople of Jena, Germany, where, in 1689, a row resulted in several deaths. In the aftermath, the university cleric addressed the town-vs-gown matter with an admonishing sermon "The Philistines Be Upon Thee", drawn from the Book of Judges (Chapt. 16, 'Samson vs the Philistines'), of the Tanakh and of the Christian Old Testament. In Word Research and Word History, the philologist Friedrich Kluge said that the word philistine originally had a positive meaning that identified a tall and strong man, such as Goliath; later the meaning changed to identify the "guards of the city".

Black Ginseng
Black ginseng is a processed ginseng which prepared by  steaming and drying of white or red ginseng  for several times (usually 9). This process resulting in extensive changes in types and amounts of several secondary metabolites. Thus, primary ginsenosides (the main active inredients in ginseng) were transformed into less polar derivatives by steaming. In addition, apparent changes happened to other secondary metabolites such as the increasing  of phenolic compounds, reducing sugars and acidic polysaccharides as well as the decrease in concentrations of free amino acids and total polysaccharides. Furthermore, the presence of some Maillard reaction products like maltol was also engaged. These obvious chemical changes were associated with a noticeable superiority for black ginseng over white and red ginseng in most of the comparative biological studies including anticarcinogenic, immunomodulatory, anti-Inflammatory, antidiabetic, hepatoprotective, antioxidant and tonic effects.

Smart Textile Materials
In the last three decades, the development of new kinds of textiles, so-called smart and interactive textiles, has continued unabated. Smart textile materials and their applications are set to drastically boom as the demand for these textiles have been increasing with the emergence of new fibers, new fabrics, and innovative processing technologies. Moreover, people are eagerly demanding washable, flexible, lightweight, and robust e-textiles. These features depend on the properties of the starting material, the post-treatment, and the integration techniques. In this work, a comprehensive review has been conducted on the integration techniques of conductive materials in and onto a textile structure. The review showed that an e-textile can be developed by applying a conductive component on the surface of a textile substrate via plating, printing, coating, and other surface techniques, or by producing a textile substrate from metals and inherently conductive polymers via the creation of fibers and construction of yarns and fabrics with these. In addition, conductive filament fibers or yarns can be also integrated into conventional textile substrates during the fabrication like braiding, weaving, and knitting or as a post-fabrication of the textile fabric via embroidering. Additionally, layer-by-layer 3D printing of the entire smart textile components is possible, and the concept of 4D could play a significant role in advancing the status of smart textiles to a new level.
