Bahá'í Faith on Life after Death
The Bahá'í Faith affirms the prospect of life after death extensively while not defining everything about it. The soul on death is said to recognize the value of its deeds and begin a new phase of a conscious relationship with God though negative experiences are possible. Others have noted the religion's stances on the afterlife.

Adaptation of Seed Germination
Environmental conditions are the basis of plant reproduction and are the critical factors controlling seed dormancy and germination. Global climate change is currently affecting environmental conditions and changing the reproduction of plants from seeds. Disturbances in germination will cause disturbances in the diversity of plant communities. Models developed for climate change scenarios show that some species will face a significant decrease in suitable habitat area. Dormancy is an adaptive mechanism that affects the probability of survival of a species. The ability of seeds of many plant species to survive until dormancy recedes and meet the requirements for germination is an adaptive strategy that can act as a buffer against the negative effects of environmental heterogeneity. The influence of temperature and humidity on seed dormancy status underlines the need to understand how changing environmental conditions will affect seed germination patterns.

Blood Typing
Blood typing is a medical laboratory test used to identify the antigens on a person's red blood cells, which determine their blood type. Routine blood typing involves determining the ABO and RhD (Rh factor) type, and is performed before blood transfusions to ensure that the donor blood is compatible. It is also used to help diagnose hemolytic disease of the newborn, a condition caused by incompatibility between the blood types of a mother and her baby. ABO typing involves both identification of ABO antigens on red blood cells (forward grouping) and identification of ABO antibodies in the plasma (reverse grouping). Other blood group antigens, such as RhC/c and E/e or Kell, may be tested for in special situations. Blood typing is usually performed using serologic methods, which use reagents containing antibodies, called antisera, to identify blood group antigens. Serologic methods rely on the ability of antibodies to cause red blood cells to clump together when they bind to antigens on the cell surface, a phenomenon called agglutination. A number of serologic methods are available, ranging from manual blood typing using test tubes or slides to fully automated systems. Blood types can also be determined through genetic testing, which is used when conditions that interfere with serologic testing are present or when a high degree of accuracy in antigen identification is required. A number of conditions can cause false or inconclusive results in blood typing. When these issues affect ABO typing, they are called ABO discrepancies. ABO discrepancies must be investigated and resolved before the person's blood type is reported. There are different procedures for resolving ABO discrepancies depending on the underlying causes. Other sources of error in blood typing include the "weak D" phenomenon, in which people who are positive for the RhD antigen show weak or negative reactions when tested for RhD, and the presence of Immunoglobulin G antibodies on red blood cells, which interferes with typing for some blood group antigens.

Cryptocurrencies in Accounting
The International Financial Reporting Standards Interpretations Committee (IFRSIC) (2019) proposed that the IAS 2 Inventories accounting standard is the accounting rule that best fits the holding of cryptocurrencies. As in the ordinary course of business, when holders want to sell their crypto assets, the best accounting rule is the IAS 2 Inventories. The IFRSIC (2019) also proposed that if the IAS 2 Inventories accounting standard is not appropriate for holdings of cryptocurrencies, another good choice is the IAS 38 Intangible Assets accounting standard. In most cases, IAS 38 will be the best accounting standard for holdings of cryptocurrencies.

Remote Attestation
Remote Attestation (RA) is a security mechanism to remotely detect adversarial presence on untrusted devices in order to guarantee their trustworthiness. RA runs as a two-party security protocol in which a trusted party (i.e., verifier) assures the integrity of the untrusted remote device (i.e., prover). Software-based RA approaches aim at verifying device integrity without relying on specialized hardware components. Despite their limited security guarantees, software-based RA approaches bring opportunities in attesting legacy and resource-constrained Internet of Things (IoT) devices, in which the presence of a hardware root-of-trust is not always a realistic assumption.

Adipose tissue in the breast
       Breast is a dynamic organ mainly composed of adipose and fibroglandular tissues. The adipose tissue extends from the collarbone to the underarm and around the center of the ribcage. Adipose tissue as an endocrine organ constantly affects the dynamics of the breast. However, the role of adipose tissue in breast has been mostly studied in terms of obesity and cancer.  In this review, we have discussed the role of breast adipose tissue in breast development from embryonic stage to mature breast. Further, we draw attention to the involvement of breast adipose tissue in pregnancy, lactation and involution associated breast changes. Finally, we depict how breast adipose tissue can affect breast cancer.

1888–1893 Uprisings of Hazaras
The 1888–1893 Uprisings of Hazaras occurred in the aftermath of the Second Anglo-Afghan War, when the Afghan Emirate signed the Treaty of Gandamak. Afghan King Abdur Rahman Khan set out to bring the Turkistan, Hazarajat and Kafiristan regions under his control. He launched several campaigns in the Hazarajat due to resistance from the Hazaras, and he conducted a widespread campaign on its population. Over sixty percent of the total Hazara population was killed with some being displaced by fleeing to Quetta and other adjoining areas. The Hazara land was distributed among loyalist villagers of nearby non-Hazaras. Moreover, many Hazaras were sold in the markets of Kabul and Qandahar. Abdur Rahman arrested Syed Jafar, chief of the Sheikh Ali Hazara tribe, and jailed him in Mazar-e-Sharif. The repression after the uprising has been called the most significant case of genocide or ethnic cleansing in the history of modern Afghanistan.

Interaction
When people communicate, information is sent, received, and interpreted between the sender  and the receiver. The information exchange often results in a closed loop, where a back and forth information transfer happens between sender and receiver . This, we refer to as an “interaction”. Rather than over a single, sequential channel, this information is often transmitted using multiple channels at once. The multiplicity of channels reduces the risk of interruptions, more so since the information channels are used in parallel, thereby increasing the seamlessness of the process. The redundancy afforded by multichannel communication increases the overall reliability of the communication, and because the decoding is distributed over a larger number of modalities and decoding modules such as sight, sound, and touch, the overall effort is reduced, even though in physical interaction there is a greater number of channels to decode.

Chaotic Image Encryption
Chaos is the characteristic of a system whose current state is guaranteed to be highly sensitive to the previous state (spatial chaos), the initial conditions (temporal chaos), or both (spatio-temporal chaos). Such a sensitivity makes the output or the behavior of a chaotic system difficult to predict. Chaos theory justifies and formulates the apparent disorder of chaotic systems on the basis of orderly patterns, structured feedback loops, iterative repetitions, self-organization, self-similarity, fractals, etc. Chaotic maps, attractors, and sequences all refer to the mathematical structures used for this formulation. Chaotic systems, maps, attractors, and sequences have been of great interest to the research community. They have been used for security purposes in a broad variety of applications ranging from smart grids to communication systems. Especially, chaotic encryption has been used for encrypting a variety of content types in addition to images.

Distributed Generation Integration into Grid
According to [25], DGs could also be defined as a small source of power production for storage (usually within the range of less than a kW and tens of MW), which is not a portion of the huge, centralized power network and is located close to the load. Another school of thought defines DGs as power pockets usually located near consumers, which have a relatively small capacity of 30 MW or less, with the ability to economically support the distribution grid. This description involves DG technologies such as photovoltaic systems, concentrating solar power, micro turbines, reciprocating engines and fuel cells.

Global Warming
Global warming is the ongoing rise of the average temperature of the Earth's climate system. It is a major aspect of climate change which, in addition to rising global surface temperatures, also includes its effects, such as changes in precipitation. While there have been prehistoric periods of global warming, observed changes since the mid-20th century have been unprecedented in rate and scale. The Intergovernmental Panel on Climate Change (IPCC) concluded that "human influence on climate has been the dominant cause of observed warming since the mid-20th century". These findings have been recognized by the national science academies of major nations and are not disputed by any scientific body of national or international standing. The largest human influence has been the emission of greenhouse gases, with over 90% of the impact from carbon dioxide and methane. Fossil fuel burning is the principal source of these gases, with agricultural emissions and deforestation also playing significant roles. Climate sensitivity to these gases is affected by feedbacks, such as loss of snow cover, increased water vapour, and melting permafrost. Land surfaces are heating faster than the ocean surface, leading to heat waves, wildfires, and the expansion of deserts. Increasing atmospheric energy and rates of evaporation are causing more intense storms and weather extremes, damaging infrastructure and agriculture. Surface temperature increases are greatest in the Arctic and have contributed to the retreat of glaciers, permafrost, and sea ice. Environmental impacts include the extinction or relocation of many species as their ecosystems change, most immediately in coral reefs, mountains, and the Arctic. Surface temperatures would stabilize and decline a little if emissions were cut off, but other impacts will continue for centuries, including rising sea levels from melting ice sheets, rising ocean temperatures, and ocean acidification from elevated levels of carbon dioxide. Mitigation efforts to address global warming include the development and deployment of low carbon energy technologies, policies to reduce fossil fuel emissions, reforestation, forest preservation, as well as the development of potential climate engineering technologies. Societies and governments are also working to adapt to current and future global warming impacts, including improved coastline protection, better disaster management, and the development of more resistant crops. Countries work together on climate change under the umbrella of the United Nations Framework Convention on Climate Change (UNFCCC), which has near-universal membership. The goal of the convention is to "prevent dangerous anthropogenic interference with the climate system". The IPCC has stressed the need to keep global warming below 1.5 °C (2.7 °F) compared to pre-industrial levels in order to avoid some irreversible impacts. With current policies and pledges, global warming by the end of the century is expected to reach about 2.8 °C (5.0 °F). At the current greenhouse gas (GHG) emission rate, the carbon budget for staying below 1.5 °C (2.7 °F) would be exhausted by 2028.

Removal of Purines from Beer
Beer corresponds to a fermented alcoholic beverage composed of several components, including purine compounds. These molecules, when ingested by humans, can be catabolized into uric acid, contributing to uric acid’s level increase in serum, which may lead to hyperuricemia and gout. To assure a proper management of this disease, physicians recommend restrictive dietary measures, particularly by avoiding the consumption of beer. Therefore, it is of relevance to develop efficient methods to remove purine compounds from alcoholic beverages such as beer. There are several enzymatic, biological, and adsorption methods reported envisaging purine compounds’ removal. Some enzymatic and biological methods present drawbacks, which can be overcome by adsorption methods. Within adsorption methods, adsorbent materials, such as activated carbon or charcoal, have been reported and applied to beer or wort samples, showing an excellent capacity for adsorbing and removing purine compounds. By ensuring the selective removal of purine compounds from this beverage, beer can be taken by hyperuricemic and gouty patients, avoiding restrictive dietary measures, while decreasing the related healthcare economic burden.

Shōgun
The Shōgun (将軍, Japanese: [ɕoːɡɯɴ] (listen); English: /ˈʃoʊɡʌn/ SHOH-gun) was the military dictator of Japan during most of the period spanning from 1185 to 1868. Nominally appointed by the Emperor, shōguns were usually the de facto rulers of the country, though during part of the Kamakura period shōguns were themselves figureheads. The office of shōgun was in practice hereditary, though over the course of the history of Japan several different clans held the position. Shōgun is the short form of Sei-i Taishōgun (征夷大将軍, "Commander-in-Chief of the Expeditionary Force Against the Barbarians"), a high military title from the Heian period and can be roughly equated with the Western rank of Generalissimus. When Minamoto no Yoritomo gained political ascendency over Japan in 1185, the title was revived to regularize his position, making him the first shōgun in the usually understood sense. The shōgun's officials were collectively referred to as the bakufu, or tent government; they were the ones who carried out the actual duties of administration, while the Imperial court retained only nominal authority. The tent symbolized the shōgun's role as the military's field commander, but also denoted that such an office was meant to be temporary. Nevertheless, the institution, known in English as the shogunate (English: /ˈʃoʊɡəneɪt/ SHOH-gə-nayt), persisted for nearly 700 years, ending when Tokugawa Yoshinobu relinquished the office to Emperor Meiji in 1867 as part of the Meiji Restoration.

Corporate Social Responsibility Preferences in South Africa
A firm’s corporate social responsibility (CSR) approach can encompass a wide variety of activities. These may include philanthropy (donating to charities), volunteering by employees, ethical labor practices, and implementing environmentally friendly operations. Diverse stakeholders and nationalities may view certain social initiatives as less or more important than others. As a result, firms respond by prioritizing those CSR activities that stakeholders in their operating environment consider important. This leads to firms having CSR preferences for some social and environmental activities over others. Traditionally, CSR in South Africa was delivered through corporate social investment (CSI): a philanthropic effort with firms implementing their social responsibility through charitable donations targeted at the education and healthcare of a firm’s surrounding communities.
