Right to Exist
The right to exist is said to be an attribute of nations. According to an essay by the nineteenth-century French philosopher Ernest Renan, a state has the right to exist when individuals are willing to sacrifice their own interests for the community it represents. Unlike self-determination, the right to exist is an attribute of states rather than of peoples. It is not a right recognized in international law. The phrase has featured prominently in the Arab–Israeli conflict since the 1950s. The right to exist of a de facto state may be balanced against another state's right to territorial integrity. Proponents of the right to exist trace it back to the "right of existence", said to be a fundamental right of states recognized by writers on international law for hundreds of years.

Carbon-based Materials for Hydrogen Storage
Carbon in its various forms (e.g., nanotubes, fullerenes, graphene) create a family of substances that enable the storage of large amounts of hydrogen in a reversible manner, which is confirmed by both computer simulations and experimental results.The main contraindication to using hydrogen as an energy source in mobile applications is still the low gravimetric density achieved by the available systems (according to the recommendations of the US Department of Energy, it should be 6 wt.%).

Kadambari
Kādambari is a romantic novel in Sanskrit. It was substantially composed by Bāṇabhaṭṭa in the first half of the 7th century CE, who did not survive to see it through completion. The novel was completed by Banabhatta's son Bhushanabhatta, according to the plan laid out by his late father. It is conventionally divided into Purvabhaga (earlier part) written by Banabhatta, and Uttarabhaga (latter part) by Bhushanabhatta. (An alternate tradition gives the son's name as Pulindabhatta.) The standard editions of the original Sanskrit text are by Peterson and Kane. There are translations into English by Kale, Layne and Ridding; and an abridgement into Gujarati by Bhalan (edited by Keshavlal Dhruv). This novel has an extremely intricate plot which is difficult to summarize concisely. Its central thread is that of a romantic attachment (and eventual union) between the hero Chandrapeeda and the heroine Kadambari. However, there are several competing subplots; indeed, the heroine does not make her appearance until past the midpoint. Many of the characters appear in multiple incarnations, some as humans and some as demigods or animals. The narration proceeds in a succession of nested frames; a large part of it is a retelling by a parrot of a story which was told to it by a sage. The latter story also contains several instances of one character relating a sub-story to another character. The plot has probably been adapted from the story of King Sumanas from Gunadhya's Brihatkatha (a conjectural collection of stories in the extinct Paishachi language). This story also appears in Somadeva's Kathasaritsagara (which is believed to be a Sanskrit precis of Gunadhya's work). This work can be plausibly claimed to be one of the first novels in the world; making due allowance for the ambiguities of such a classification. In fact, two modern Indian languages (Kannada and Marathi) use 'kadambari' as a generic term for a romance or a novel. Apart from the Kadambari, Banabhatta is also the author of Harshacharita, a biography of his patron king Harshavardhana. It is this circumstance which allows one to date the author with a reasonable degree of certainty.

Energy Piles
Energy piles are a relatively new technology that have dual function as heat transferring and load bearing. Due to the influence of temperature cycles, additional thermal stress and relative displacement of the pile will be generated; this is different from the load transferring mechanism of the conventional pile. In order to study the thermodynamic characteristics of the energy pipe pile under dual working conditions and temperature cycles, field tests were carried out on the PHC (prestressed high-strength concrete) energy pipe pile without constraining on the top of the piles. Displacement gauges were arranged on the top of the pile, and concrete strain gauges (temperature, strain) were embedded in the pile.

Emirate of Ras Al Khaimah
Ras Al Khaimah (RAK) (Arabic: رَأْس ٱلْخَيْمَة; IPA: [raʔs lˈxajma]), also spelled as Ras al Khaimah or Ras al-Khaimah, is one of the seven emirates that make up the United Arab Emirates (UAE). The city of Ras Al Khaimah, sometimes simply abbreviated to RAK City, is the capital of the emirate and home to most of the emirate's residents. It is linked to the medieval trading port of Julfar.[lower-alpha 1] Its name in English means "top of the tent". The emirate borders Oman's exclave of Musandam, and occupies part of the same peninsula. It covers an area of 2,486 km2 (960 sq mi) and has 64 km (40 mi) of beach coastline. As of 2015, the emirate had a population of about 345,000, of which about 31% were Emirati citizens. RAK city has two main areas - the Old Town and Nakheel - on either side of a creek that is home to mangroves and is framed by the North-Western Hajar Mountains. The emirate also consists of several villages and new gated residential developments, such as Al Hamra Village and Mina Al Arab. The emirate is served by Ras Al Khaimah International Airport. Its geography consists of a northern part (where Ras Al Khaimah City and most towns are situated) and a large southerly inland exclave (near the Dubai exclave of Hatta), and a few small islands in the Persian Gulf. Ras Al Khaimah has the most fertile soil in the country, due to a larger share of rainfall and underground water streams from the Hajar.

Storage of Cereals in Warehouses
Storage of Cereals in Warehouses refers to the methods of how people restore the cereals. In this entry, we depict the development history and basic storage information. For decades, the use of various synthetic pesticides has been the key factor in the proper and long-term storage of cereals. Unfortunately, we are faced with non-acceptable data regarding the effects of synthetic pesticides. Due to this, further steps have been made in order to take measures to reduce the use and risk of chemical pesticides by 50% by 2030 and to reduce the use of more dangerous pesticides by 50% by 2030. The concept of integrated pest management has been promoted as a dynamic and flexible approach leading to the reduction of chemical pesticide usage and their negative effects on the environment.

Process of Apoptosis
The term “Apoptosis” originates from Greek, which means the shedding of leaves from trees in autumn or the falling of petals from flowers. Apoptosis was firstly utilized by Kerr, Wyllie, and Currie in 1972 for explaining a morphologically discrete way of cell death. However, multiple concepts of apoptosis were precisely explained several years back. The main concept of apoptosis emerged from the knowledge of the process of programmed cell death that takes place in the developmental cycle of Caenorhabditis elegans.

Oligarchy
Oligarchy (from el ὀλιγαρχία (oligarkhía); from ὀλίγος (olígos) 'few', and ἄρχω (arkho) 'to rule or to command') is a form of power structure in which power rests with a small number of people. These people may be distinguished by nobility, wealth, family ties, education or corporate, religious or political, military control. Such states are often controlled by families who typically pass their influence from one generation to the next, but inheritance is not a necessary condition for the application of this term. Throughout history, oligarchies have often been tyrannical, relying on public obedience or oppression to exist. Aristotle pioneered the use of the term as a synonym for rule by the rich, for which another term commonly used today is plutocracy. Although an oligarchy is usually seen as tyrannical, most modern states rely on some form of oligarchy, usually in the form of representative officials deciding national policy. The concern of tyranny usually occurs when the rule of law is violated or when there's limited separation of powers. Especially during the fourth century BCE, after the restoration of democracy from oligarchical coups, the Athenians used the drawing of lots for selecting government officers to counteract what the Athenians saw as a tendency toward oligarchy in government if a professional governing class were allowed to use their skills for their own benefit. They drew lots from large groups of adult volunteers to pick civil servants performing judicial, executive, and administrative functions (archai, boulē, and hēliastai). They even used lots for posts, such as judges and jurors in the political courts (nomothetai), which had the power to overrule the Assembly.
