Acinonychini
The feline tribe Acinonychini contains three genera, each with one extant species: the cougar in Puma, the jaguarundi in Herpailurus, and the cheetah in Acinonyx. In addition, a handful of extinct fossil species have been found in Eurasia and the Americas. The evolutionary relationships of these cats still needs to be worked out, with the main focus being the placement of the extinct species in relation to the extant species, and where cheetahs evolved. While cheetahs and cougars are sometimes considered big cats, as felines, they are more closely related to domestic cats than they are to pantherines such as lions and leopards.

GPS Block IIIA
GPS Block IIIA consists of the first ten (known as "tranche") of GPS III satellites, which will be used to keep the Navstar Global Positioning System operational. Lockheed Martin designed, developed and manufactured the GPS III Non-Flight Satellite Testbed (GNST) and all ten Block IIIA satellites. The first satellite in the series was projected to launch in 2014, but significant delays have pushed the scheduled launch to December 2018. The tenth and final GPS Block IIIA launch is projected in Q2 2023.

Fujiko
Fujiko (富士講) is a Japanese religious group. One of the popular beliefs established in the Edo period, especially in the Kanto centered on Edo, with a lineage of Kakugyo. The term "Fujikō" is usually used to refer to the religious system and religious movement in general. The term is also sometimes used to refer to Mount Fuji and its divine spirits. The activities of the Fuji-kō consist of regular events called "ogami" and climbing Mt. At the Ogami, they read the "Otsutae (Report)," a sutra of devotional service, and perform the "Otakiaage (burning up)" using an assembled altar called the "Ogami Dance (Worship Chest). There are also examples of Fuji Mounds (sometimes natural mountains are used instead) built with stones and earth to worship the god of Mt. Fuji as a place of worship (see the article on Fuji Mound for details). Oshi was the leader of the faith taught by Kakugyo, and at the same time, he was responsible for providing accommodations for the members of the Fuji-kō when they climbed Mt. During the closing period of the mountain, Goshi would visit Fuji-kō in Edo and other areas to preach the teachings. In the summer, when Mt. Fuji was about to open, Fuji-kō members came one after another to Goshi's homes in Kawaguchi and Yoshida, and he provided them with lodgings, information about the mountain trail, food and equipment necessary for climbing, and various other services. In the Edo period (1603–1868), "Fuji-kō" in the narrow sense referred only to the activities of masters in Yoshida, and the activities of masters in Kawaguchi, Sushiri, Suyama, and other areas outside Yoshida, as well as the relationship between masters and leaders, were not included in "Fuji-kō," and there is a suggestion that this was the more common form.。 In addition to the above, Fuji-kō (Asama-kō) is also a name for a group of people who believe in Fuji, derived from Shugendo. It is distributed in the Chubu region and Kinki region, but the actual situation differs greatly from the above, and is characterized by water practices (Fuji sakurei) held near water in early summer. They also climb Mt. Fuji, but they alternate climbing Ominesan every other year, a behavior not seen in the Kanto region.

Sacca-kiriya
Sacca-kiriyā (Pāli; Sanskrit: satya-kriya, but more often: satyādhiṣṭhāna), is a solemn declaration of truth, expressed in ritual speech. Most often found in Buddhism, it can be an utterance with regard to one's own virtue, or with regard to a certain fact, followed by a command or resolution. Such a statement is believed to effect a wonder-working power that can benefit oneself and others, depending on the truthfulness of the person making the statement. The sacca-kiriyā is a motif found in the stories of the Buddhist Pali Canon and its commentaries, as well as in post-canonical works such as the Milindapañhā and the Avadānas. In these stories it is found usually as a blessing, but sometimes as a curse. The motif can also be found in Hindu and Jain texts. The sacca-kiriyā presumes a moral force of truth that is operating in the world, and is stronger than gods or humans. Although sacca-kiriyā often refer to characteristics of the Buddha, the Buddhist teaching, and the monastic community, it can also refer to facts with regard to natural phenomena, such as the sun or the moon. Some scholars believe that the effectiveness of a sacca-kiriyā as portrayed in stories depends on virtue and good character, whereas other scholars understand the sacca-kiriyā to be merely about speaking according to facts. Scholars theorize that the sacca-kiriyā is an ancient belief that precedes Buddhism, but was used in Buddhism as a teaching device to explain Buddhist ethics and other teachings. The principles underlying the sacca-kiriyā have also been connected with Mahatma Gandhi's ideal of non-violent resistance, and many other aspects of Asian culture and religious life.

Systems of Social Stratification
Detailed anthropological and sociological studies have been made about customs of patrilineal inheritance, where only male children can inherit. Some cultures also employ matrilineal succession, where property can only pass along the female line, most commonly going to the sister's sons of the decedent; but also, in some societies, from the mother to her daughters. Some ancient societies and most modern states employ egalitarian inheritance, without discrimination based on gender and/or birth order.

Transcendence
In philosophy, transcendence is the basic ground concept from the word's literal meaning (from Latin), of climbing or going beyond, albeit with varying connotations in its different historical and cultural stages. It includes philosophies, systems, and approaches that describe the fundamental structures of being, not as an ontology (theory of being), but as the framework of emergence and validation of knowledge of being. "Transcendental" is a word derived from the scholastic, designating the extra-categorical attributes of beings.

Cashew Production in Tanzania
Tanzania is one of the largest cashew producers in Africa, with exports providing 10-15 percent of the country's foreign exchange. The country is the eighth-largest grower of cashew nut in the world and ranks fourth in Africa. The country provides 20% of Africa's cashew nut and only trails in production of Nigeria, Cote D'Ivoire, and Guinea-Bissau, according to figures released in 2012 by United Nations Food and Agricultural Organisation (FAO). The country has been engaged in the production of the cash crop since before independence in the years 1960s however, poor regulation and lack of reliable payments to farmers have posed significant challenges to the Cashew Nut farming industry in Tanzania. Guinea-Bissau, a country a tenth of the area of Tanzania's, has a significantly greater yield. The cash crop is usually cultivated in the southern coastal regions of the country, near the towns of Mtwara, Kilwa and Dar es Salaam. The sale and marketing of the product is run by the Cashewnut Board of Tanzania, through various farmer co-operatives. More than ninety percent of the exports are destined for India and almost entirely in raw form. The lack of domestic processing firms costs the country vital foreign revenues and thousands of jobs. The Tanzanian government has been facing challenges for finding potential investors in order to revive the cashew processing industry in Tanzania.

Digital Versus Film Photography
The merits of digital versus film photography were considered by photographers and filmmakers in the early 21st century after consumer digital cameras became widely available.

In the 21st century, photography came to be predominantly digital, but traditional photochemical methods continue to serve many users and applications.
