Women in Positions of Power
Women in positions of power are women who hold an occupation that gives them great authority, influence, and/or responsibility. Historically, power has been distributed among the sexes disparately. Power and powerful positions have most often been associated with men as opposed to women. As gender equality increases, women hold more and more powerful positions. Accurate and proportional representation of women in social systems has been shown to be important to the long-lasting success of the human race. Additionally, a study shows that “absence is not merely a sign of disadvantage and disenfranchisement, but the exclusion of women from positions of power also compounds gender stereotypes and retards the pace of equalization".

Tumor Invasion and Metastasis
Metastasis is considered one of the hallmarks of cancer and enhanced tumor invasion and metastasis is significantly associated with cancer mortality. Metastasis occurs via a series of integrated processes involving tumor cells and the tumor microenvironment. The innate immune components of the microenvironment have been shown to engage with tumor cells and not only regulate their proliferation and survival, but also modulate the surrounding environment to enable cancer progression.

Trough (Meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong and Fiji, it is represented by a bold line extended from a low pressure center or between two low pressure centers; in Macau and Australia, it is a dashed line. If they are not marked, troughs may still be identified as an extension of isobars away from a low pressure center.

Mannequin Challenge
File:Mannequin challenge JU Engineers.webm The Mannequin Challenge was a viral Internet video trend which became popular in November 2016, in which people remain frozen in action like mannequins while a moving camera films them, often with the song "Black Beatles" by Rae Sremmurd playing in the background. The hashtag #MannequinChallenge was used for popular social media platforms such as Twitter and Instagram. It is believed that the phenomenon was started by students at a high school in Jacksonville, Florida. The initial posting has inspired works by other groups, especially professional athletes and sports teams, who have posted increasingly complex and elaborate videos. News outlets have compared the videos to bullet time scenes from science fiction films such as The Matrix, X-Men: Days of Future Past, X-Men: Apocalypse, Lost in Space or Buffalo '66. Meanwhile, the participatory nature of the challenge on social media makes it similar to memes such as Makankosappo or the Harlem Shake. Others have noted similarities with the HBO TV series Westworld, which debuted around the same time, where robotic hosts can be stopped in their tracks.

Traditional Balsamic Vinegar Processing
The most known and traditional vinegar is the one that is made from wine. For its production, the grape must undergo alcohol fermentation and the posterior oxidation of ethanol to acetic acid. Yeasts and acetic acid bacteria (AAB) carry out the biochemical processes in sequence. The process of wine acetification can be achieved by slow traditional processes (the Orléans or French methods) or by a quick submerged industrial process. High-quality vinegar is usually produced by traditional methods using oak casks, once the wood allows the continuous aeration of the acetic bacteria culture. Sour–sweet vinegar presents a balance of both bitter/sour and sweet flavors. The sourness typically comes from acetic acid, while the sweetness can come from the type of fruit or the amount of sugar present at the end of vinegar production. In general, sour-sweet vinegar has a more complex and nuanced flavor profile compared to regular vinegar, which is often simply sour. One kind of vinegar produced by wine acetification where yeasts and bacteria co-exist and produce savory vinegar is traditional balsamic vinegar (TBV).

Drone Brood
Drone brood homogenate (known as apilarnil or less apistimul) is a bee product obtained by the collection of drone (male honeybees)  larvae from drone cells of honey comb, from 3 to 11 days after hatching. Apilarnil, which may be defined as the male equivalent of royal jelly, is obtained from drone brood and then freeze-dried. Etymologically, the term originates from “api” for bee, “lar” for larvae, and “nil” as a shortened form of its discoverer’s name - Romanian apitherapist Nicholae Iliesiu.

Natural Convection
Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow. Convective flow may be transient (such as when a multiphase mixture of oil and water separates) or steady state (see Convection cell). The convection may be due to gravitational, electromagnetic or fictitious body forces. Heat transfer by natural convection plays a role in the structure of Earth's atmosphere, its oceans, and its mantle. Discrete convective cells in the atmosphere can be identified by clouds, with stronger convection resulting in thunderstorms. Natural convection also plays a role in stellar physics. Convection is often categorised or described by the main effect causing the convective flow, e.g. Thermal convection. Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place.

Occultism in Nazism
Nazism and occultism describes a range of theories, speculation and research into the origins of Nazism and its possible relation to various occult traditions. Such ideas have been a part of popular culture since at least the early 1940s, during World War II, and gained renewed popularity starting in the 1960s. There are documentaries and books on the topic, among the most significant are The Morning of the Magicians (1960) and The Spear of Destiny (1972). Nazism and occultism has also been featured in numerous films, novels, comic books and other fictional media. Some good examples are the film Raiders of the Lost Ark (1981) and the comic book series Hellboy. Historian Nicholas Goodrick-Clarke analyzed the topic in The Occult Roots of Nazism in which he argued there were in fact links between some ideals of Ariosophy and Nazi ideology. He also analyzed the problems of the numerous popular occult historiography books written on the topic. He sought to separate empiricism and sociology from the modern mythology of Nazi occultism that exists in many books which "have represented the Nazi phenomenon as the product of arcane and demonic influence". He considered most of these to be "sensational and under-researched".

Land Administration and Blockchain Technology
Transparency of processes is very crucial across all institutions. In land administration processes, this is particularly important given the multi-stakeholder involvement. This paper argues that transparency of land administration processes involves carrying out and sharing up-to-date information on ownership, value, and the use of land and all of its associated resources among related institutions, right holders and other stakeholders, including third parties, as well as, acting on the information in an open manner. To achieve this in Ghana, blockchain technology has been identified as a complementary tool to the Ghanaian land administration system. Blockchain technology refers to a fully distributed crypto-graphical system that captures and stores a consistent, immutable and linear event log of the transactions between networked actors. The study identifies that given the potentials of blockchain technology which include; decentralization of transaction to all connected stakeholders, the immutability of records, hashing of records that allows for quick access to both historical and current land transactions' data, as well as the blockchain smart contract among others, land administration processes of land tenure, land valuation, land use planning, and land development will benefit from openness, and transparency, and human error elimination. It will also eliminate fraud, and double sales of land among other land challenges identified in the Ghanaian land sector.  The study proposes that for real-time land up-date in land information across all the land sector divisions; land valuation division, land title registration, survey and mapping division, and the public and vested land management division, a permisionless public blockchain architecture be adopted for the Ghanaian land system. This is because, in comparison to the other blockchain architecture types, the permisionless public blockchain allows more transparency, decentralization, openness, integration, and also adheres to privacy and data protection laws. This study and its results are particularly important not only to the Ghanaian land sector and its stakeholders, but to all other land administration systems in the sub-Saharan Africa region given the similarities in land administration across the region. In the Ghanaian context however, the study's findings if implemented will affect the institutional relations and shared authorities between all stakeholders which include government agencies, local chiefs and individual landowners. This is because, land decisions and land data will not become shared responsibility of all stakeholders and not dependent on just some few stakeholders. A successful implementation of blockchain in Ghana's land administration will however depend on negotiations and consensus amongst the different land stakeholder, education of all stakeholders on the technology, and its impacts, as well as standardization in the land administration processes across the different land divisions. This is because, where there is no such standardization, there is a high possibility of inconsistencies and irregularities in the processes which can affect the efficient working of the blockchain system.

Thiosugars of Biological Significance
Thiosugars are important compounds because of their structural complexity and crucial biological activities. Therefore, a series of methods are developed for their synthesis using new methods. Unlike, oxygen sugars, thiosugars are more stable and therefore, much scope exists to alter their structures by chemical manipulations. Notably, thiosugars can act as glycosyl donors as well as acceptors.  Many functionalized thiosugars occur naturally and are potential targets for therapeutics. Synthesis of thiosugars following convergent route is a challenge.  Over the years, scientists have explored thiosugars through numerous green and sustainable methods. These studies are highly significant and timely since it opens the door towards carbohydrate-based drugs.

Sound Transmission Losses in DPS
Double panel structures (DPS) are flat or curved structural designs which consist of two opposite facesheets or panels separated by a core or cavity. The cavity may be any kind of enclosed gasses while the core may be any form of solid materials which can be architecturally designed. DPS have been used in various applications for sound insulation purpose.  First, sound incident on the incident facesheet of the DPS, transmitted through the core or cavity and then radiates from the radiating facesheet of the DPS. The ratio of the sound power incident on the incident facesheet to the sound power transmitted through the radiating facesheet is referred as the sound transmission loss of the DPS. The motivation behind the wide industrial application of DPS is owing to their potential characteristics to absorb sound more effectively. Therefore, it is of utmost importance to understand the different geometry and material constituents of the facesheets as well as core/cavity of the DPS. The knowledge of this will help designers and manufacturers to produce the most effective and optimal design of DPS capable of producing very high and desirable sound transmission losses.
