Industrie 4.0 in China
Industrie 4.0 has stirred turbulences in China since its birth in 2011. The struggles of the Chinese manufacturing enterprises towards realizing and adapting Industrie 4.0 in their production processes have given people many new perceptions. The 3rd Industrial Revolution was the biggest beneficiary of globalization. The first ten years of Industrie 4.0 also benefitted from globalization as its influence got widespread throughout the world. Globalization originated from the need to optimize the allocation of global resources and the formation of industrial value chains under the impetus of the international division of labor. Globalization is facing more and more challenges in the international economic development.

Yamhad Dynasty
Template:Royal house The Yamhad dynasty was an ancient Amorite royal family founded in c. 1810 BC by Sumu-Epuh of Yamhad who had his capital in the city of Aleppo. Started as a local dynasty, the family expanded its influence through the actions of its energetic ruler Yarim-Lim I who turned it into the most influential family in the Levant through both diplomatic and military tools. At its height the dynasty controlled most of northern Syria and the modern Turkish province of Hatay with a cadet branch ruling in the city of Alalakh (Land of Mukish). The dynasty was ousted during a short Hittite occupation of Aleppo in the beginning of the 16th century BC but was restored and expanded the kingdom again before being driven out of Aleppo by the Mitannians in c. 1524. Idrimi a member of the dynasty was able to conquer Alalakh leaving his descendents to rule until the last of them was dethroned by the Hittite king Suppiluliuma I in c. 1344 BC.

Classification and Application of Natural Polymers
Natural polysaccharides are some of the most extensively used biopolymers in food, pharmaceutical, and medical applications, because they are renewable and have a high level of biocompatibility and biodegradability. The fundamental understanding required to properly exploit polysaccharides potential in the biocomposite, nanoconjugate, and pharmaceutical industries depends on detailed research of these molecules. Polysaccharides are preferred over other polymers because of their biocompatibility, bioactivity, homogeneity, and bioadhesive properties. Natural polysaccharides have also been discovered to have excellent rheological and biomucoadhesive properties, which may be used to design and create a variety of useful and cost-effective drug delivery systems. Polysaccharide-based composites derived from natural sources have been widely exploited due to their multifunctional properties, particularly in drug delivery systems and biomedical applications. These materials have achieved global attention and are in great demand because to their biochemical properties, which mimic both human and animal cells.

Performance and Efficiency of Cross-Flow Fans
Cross-Flow Fans (CFFs) have been widely applied in the automotive and domestic air conditioning industries in recent decades. They are high-pressure coefficient turbomachines compacted diametrically, and thus, the complex interactions of these fans require thorough evaluation. Their innovation has opened up new directions in turbomachinery, and both academic research and industry have seen numerous efforts to develop these types of fans. Despite extensive work, optimizing and improving their performance remains a challenge. Enhancing their efficiency necessitates improvements in structural characteristics, aerodynamic features, and acoustic properties.

Conceptualizing Future Generations as Stakeholders
Many investors think in terms of MSV (maximization of the shareholder value) and fail to consider other important stakeholders. Future generations will “inherit” the results of the actions of current generations. Investing money in some lucrative ideas is definitely a very important financial activity, but it must be done responsibly. The Sustainable Development Goals (SDGs) postulated by the UN; the Environmental, Social, and Governance (ESG) criteria; and the Equator Principles are some notions proposed to be considered to make investors’ actions more responsible. Future generations deserve a better, safer, and unwasted place to live in, so it is the right time to start thinking of them as major stakeholders.

Biopolymers in Textiles
Given the significant contamination of our ecosystem caused by synthetic fibers involved in the textile industry, biomaterials derived from renewable resources or endowed with biodegradability characteristics have been proposed as a possible green solution for reducing the environmental impact of fabric production. The use of polymers derived from renewable sources (both biodegradable and non-biodegradable) would result in reduced greenhouses emissions (GHG) and fossil fuel consumption (FFC) when compared to common fossil-based, non-biodegradable polymers, the most common polyester (PET), polyamide (PA), polypropylene (PP). Although less biodegradable compared to natural-based fibers (wool, cotton), aliphatic polyester bio-based fibers are biodegraded more quickly compared to PET fibers. Furthermore, the larger moisture vapor transmission of bio-based polymers compared to PET, PA and PP materials, allows greater breathability by corresponding fabrics. Biobased fibers are also endowed with good mechanical resistance and antibacterial properties, low flammability and less smoke generation.

Globalization and Female Employment
Globalization can be viewed as a world integration leading to an exchange of ideas in different cultural, economic, political, technical, and social spheres across countries. Globalization’s impact on the receiving country’s economic and employment outcomes is an established phenomenon. However, globally only about 55 percent of women participate in the labor force compared to 80 percent for men. These gender disparities serve as an important focal point for research related to female employment, as it has a significant positive association with overall socio-economic outcomes.

Arsenic Toxicity in Plants
 The non-essential metalloid arsenic (As) is widely distributed in soil and underground water of many countries. Arsenic contamination is a concern because it creates threat to food security in terms of crop productivity and food safety. Plants exposed to As show morpho-physiological, growth and developmental disorder which altogether result in loss of productivity. At physiological level, As-induced altered biochemistry in chloroplast, mitochondria, peroxisome, endoplasmic reticulum, cell wall, plasma membrane causes reactive oxygen species (ROS) overgeneration which damage cell through disintegrating the structure of lipids, proteins, and DNA. Therefore, plants tolerance to ROS-induced oxidative stress is a vital strategy for enhancing As tolerance in plants. Plants having enhanced antioxidant defense system show greater tolerance to As toxicity. Depending upon plant diversity (As hyperaccumulator/non-hyperaccumulator or As tolerant/susceptible) the mechanisms of As accumulation, absorption or toxicity response may differ. There can be various crop management practices such as exogenous application of nutrients, hormones, antioxidants, osmolytes, signaling molecules, different chelating agents, microbial inoculants, organic amendments etc. can be effective against As toxicity in plants.

Entrance Length
In fluid dynamics, the entrance length is the distance a flow travels after entering a pipe before the flow becomes fully developed. Entrance length refers to the length of the entry region, the area following the pipe entrance where effects originating from the interior wall of the pipe propagate into the flow as an expanding boundary layer. When the boundary layer expands to fill the entire pipe, the developing flow becomes a fully developed flow, where flow characteristics no longer change with increased distance along the pipe. Many different entrance lengths exist to describe a variety of flow conditions. Hydrodynamic entrance length describes the formation of a velocity profile caused by viscous forces propagating from the pipe wall. Thermal entrance length describes the formation of a temperature profile. Awareness of entrance length may be necessary for the effective placement of instrumentation, such as fluid flow meters.

Back Dorm Boys
The Back Dorm Boys is a Chinese duo who gained fame for their lip sync videos to songs by the Backstreet Boys and other pop stars. Their videos, captured on a low quality Web cam in their college dorm room, have been viewed by Internet users within China and around the world. Many of their videos can be seen on YouTube, giving them YouTube fame. The two, Wei Wei (simplified Chinese: 韦炜; traditional Chinese: 韋煒; pinyin: Wéi Wěi) and Huang Yixin (simplified Chinese: 黄艺馨; traditional Chinese: 黃藝馨; pinyin: Huáng Yìxīn), were sculpture majors at the Guangzhou Academy of Fine Arts (simplified Chinese: 广州美术学院; traditional Chinese: 廣州美術學院; pinyin: Gǔangzhōu Měishù Xuéyuàn). The Dormitory Boys, a blog of note on Blogger, which some believe is not maintained by the Back Dorm Boys, but written by a ghostwriter, took requests, asking fans to recommend a song they should lip sync to. In January 2006, a poll was conducted from songs picked from 427 requests received 2005, December. The Black Eyed Peas' song "My Humps" won the poll, but the Back Dorm Boys lip synced to the song "Don't Lie" by the Black Eyed Peas instead, which was a huge hit on YouTube as well as their host country. They are apparently producing a drama, according to their official blog. They are featured in one Mainland China sitcom, or drama, called Nonstop (青春进行时).

Diabrotica Species
The genus Diabrotica has over 400 described species, the majority of them neotropical. However, only three species of neotropical Diabrotica are considered agricultural pests, D. speciosa, D. balteata, and D. viridula. D. speciosa and D. balteata are polyphagous both as adults and during the larval stage. D. viridula are stenophagous during the larval stage, feeding essentially on maize roots, and polyphagous as adults. The larvae of the three species are pests on maize, but D. speciosa larvae also feed on potatoes and peanuts, while D. balteata larvae feed on beans and peanuts. None of these species express a winter/dry season egg diapause, like several North American species. Instead they have several continuous, latitude-mediated generations per year. This hinders the use of crop rotation as a management tool, although early planting can help in the temperate regions of the distribution of D. speciosa. Their know parasitoids do not exert much control on Diabrotica populations, or show potential for inundative biocontrol plans. Management options are limited to insecticide applications and Bt GM maize. Other techniques that show promise are products using Beauveria bassiana and Heterorhabditis bacteriophora, semiochemical attractants for monitoring purposes or as toxic baits, and plant resistance.

SUSE Linux Enterprise Desktop
SUSE Linux Enterprise Desktop (SLED), introduced as Novell Linux Desktop, is a Linux distribution supplied by SUSE and targeted at the business market. It is targeted for desktops. New major versions are released at an interval of 24–36 months, while minor versions (called service packs) are released every 9–12 months. SUSE Linux Enterprise products, including SUSE Linux Enterprise Desktop, receive commercial support and much more intense testing than the openSUSE community product, with the intention that only mature, stable versions of the included components will make it through to the released enterprise product. The current version is SLED 15, which is developed from a common codebase with SUSE Linux Enterprise Server (SLES) and other SUSE Linux Enterprise (SLE) products. SLED includes the GNOME Shell, LibreOffice, Evolution and many other popular open source packages such as Dia, TigerVNC, and lftp. Like SLES, SLED is based on openSUSE Tumbleweed and shares a common codebase with openSUSE Leap. On 15 March 2019, EQT Partners completed its acquisition of SUSE for 2.5 billion USD, leaving SUSE one of the largest independent enterprise Linux vendors.
