Merchant Vessel
A merchant vessel, trading vessel or merchantman is a boat or ship that transports cargo or carries passengers for hire. This excludes pleasure craft that do not carry passengers for hire; warships are also excluded. They come in a myriad of sizes and shapes, from twenty-foot inflatable dive boats in Hawaii, to 5,000 passenger casino vessels on the Mississippi River, to tugboats plying New York Harbor, to 1,000 foot oil tankers and container ships at major ports, to a passenger carrying submarine in the U.S. Virgin Islands. Most countries of the world operate fleets of merchant ships. However, due to the high costs of operations, today these fleets are in many cases sailing under the flags of nations that specialize in providing manpower and services at favourable terms. Such flags are known as "flags of convenience". Currently, Liberia and Panama are particularly favoured. Ownership of the vessels can be by any country, however. The Greek-owned fleet is the largest in the world. Today, the Greek fleet accounts for some 16 per cent of the world’s tonnage; this makes it currently the largest single international merchant fleet in the world, albeit not the largest in history. During wars, merchant ships may be used as auxiliaries to the navies of their respective countries, and are called upon to deliver military personnel and materiel.

Socialist State
A socialist state, socialist republic, or socialist country, sometimes referred to as a workers' state or workers' republic, is a sovereign state constitutionally dedicated to the establishment of socialism. The term communist state is often used synonymously in the West specifically when referring to one-party socialist states governed by Marxist–Leninist communist parties, despite these countries being officially socialist states in the process of building socialism. These countries never describe themselves as communist nor as having implemented a communist society. Additionally, a number of countries that are multi-party capitalist states make references to socialism in their constitutions, in most cases alluding to the building of a socialist society, naming socialism, claiming to be a socialist state, or including the term people's republic or socialist republic in their country's full name, although this does not necessarily reflect the structure and development paths of these countries' political and economic systems. Currently, these countries include Algeria, Bangladesh, Guyana, India, Nepal, Nicaragua, Portugal, Sri Lanka and Tanzania. The idea of a socialist state stems from the broader notion of state socialism, the political perspective that the working class needs to use state power and government policy to establish a socialised economic system. This may either mean a system where the means of production, distribution and exchange are nationalised or under state ownership, or simply a system in which social values or workers' interests have economic priority. However, the concept of a socialist state is mainly advocated by Marxist–Leninists and most socialist states have been established by political parties adhering to Marxism–Leninism or some national variation thereof such as Maoism, Stalinism or Titoism. A state, whether socialist or not, is opposed the most by anarchists, who reject the idea that the state can be used to establish a socialist society due to its hierarchical and arguably coercive nature, considering a socialist state or state socialism as an oxymoron. The concept of a socialist state is also considered unnecessary or counterproductive and rejected by some classical, libertarian and orthodox Marxists, libertarian socialists and other socialist political thinkers who view the modern state as a byproduct of capitalism which would have no function in a socialist system. A socialist state is to be distinguished from a multi-party liberal democracy governed by a self-described socialist party, where the state is not constitutionally bound to the construction of socialism. In such cases, the political system and machinery of government is not specifically structured to pursue the development of socialism. Socialist states in the Marxist–Leninist sense are sovereign states under the control of a vanguard party which is organizing the country's economic, political and social development toward the realization of socialism. Economically, this involves the development of a state capitalist economy with state-directed capital accumulation with the long-term goal of building up the country's productive forces while simultaneously promoting world communism. Academics, political commentators and other scholars tend to distinguish between authoritarian socialist and democratic socialist states, with the first representing the Soviet Bloc and the latter representing Western Bloc countries which have been democratically governed by socialist parties such as Britain, France, Sweden and Western social-democracies in general, among others.

People's Party of Canada
The People's Party of Canada (PPC; French: Parti populaire du Canada or simply People's Party) is a federal political party in Canada. The party was formed by Maxime Bernier in September 2018, shortly after his resignation from the Conservative Party of Canada. Bernier, the Member of Parliament for Beauce and a former cabinet minister, was the party's only MP from its founding in 2018 to his defeat in the 2019 Canadian federal election. Bernier had represented the Quebec riding in Parliament from 2006, when he was elected as a Conservative. The party has been referred to as conservative, libertarian, populist,, and classical liberal, while being seen on the right-wing to far-right of the traditional left-right political spectrum. The PPC formed electoral district associations (EDAs) in all of Canada's 338 ridings and ran a full slate of candidates in the 2019 federal election, but no candidate was elected under its banner and Bernier lost his bid for personal re-election in Beauce.

Purification of Biodiesel Glycerol from Waste Oils
To facilitate the glycerol purification, it is important to know the composition of glycerol from the biodiesel obtained from waste oils and how these oils and the type of biodiesel synthesis influence the glycerol composition. First, different glycerol impurities were studied based on the oil origin and the used catalysts. Thus, the glycerol impurities are detailed to show their influence on the glycerol or on its transformation in other products. Different glycerol characterization techniques were used to determine the purity level and properties of glycerol. The main interest of this part is to describe different methods to purify glycerol and to understand its composition and its utilization.

Hybrid Plant
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering times, pollen vectors, inhibition of pollen tube growth, somatoplastic sterility, cytoplasmic-genic male sterility and the structure of the chromosomes. A few animal species and many plant species, however, are the result of hybrid speciation, including important crop plants such as wheat, where the number of chromosomes has been doubled. Human impact on the environment has resulted in an increase in the interbreeding between regional species, and the proliferation of introduced species worldwide has also resulted in an increase in hybridisation. This genetic mixing may threaten many species with extinction, while genetic erosion from monoculture in crop plants may be damaging the gene pools of many species for future breeding. A form of often intentional human-mediated hybridisation is the crossing of wild and domesticated species. This is common in both traditional horticulture and modern agriculture; many commercially useful fruits, flowers, garden herbs, and trees have been produced by hybridisation. One such flower, Oenothera lamarckiana, was central to early genetics research into mutationism and polyploidy. It is also more occasionally done in the livestock and pet trades; some well-known wild × domestic hybrids are beefalo and wolfdogs. Human selective breeding of domesticated animals and plants has resulted in the development of distinct breeds (usually called cultivars in reference to plants); crossbreeds between them (without any wild stock) are sometimes also imprecisely referred to as "hybrids". Hybrid humans existed in prehistory. For example, Neanderthals and anatomically modern humans are thought to have interbred as recently as 40,000 years ago. Mythological hybrids appear in human culture in forms as diverse as the Minotaur, blends of animals, humans and mythical beasts such as centaurs and sphinxes, and the Nephilim of the Biblical apocrypha described as the wicked sons of fallen angels and attractive women.

Caste Spaces in Pakistan
This study is an attempt to understand the appropriation of spaces of Dalits by Sindhi progressive activists and short story writers in Pakistan as they construct or rather undermine caste at the anvil of religion and gender to reframe their own religio-political agenda premised on political Sufism or Sufi nationalism. I specifically discuss the narratives emergent of the three popular short stories that are reframed as having exceptional emancipatory potential for the Dalits. Assessing the emancipatory limits of Sindhi progressive narrative, I argue while that the short stories purport to give fuller expression to religious, gender-based and class dimension of the problematic, it elides the problem of casteism and the subsequent existential demand of Dalit emancipation. Given the hegemonic influence of local Ashrafia class, the internal caste frictions are glossed over through political Sufism or Sindhi nationalism. This gloss of politicised Sufism hampers Dalit agency and rather facilitates the appropriation of Dalit spaces by Ashrafia class. This leads to conclude that the seemingly progressive literary-political narratives framed in religio-political idiom may offer to the oppressed not more than a token sympathy, compassion, self-pity and false pride in legends. Instead, they allow the appropriation of spaces and events of the oppressed, and the objectification of oppressed bodies by the oppressor.

Laïcité
Laïcité ([la.i.si.te]), literally "secularity", is a French concept of secularism. It discourages religious involvement in government affairs, especially religious influence in the determination of state policies; it also forbids government involvement in religious affairs, and especially prohibits government influence in the determination of religion. Laïcité does not preclude a right to the free exercise of religion. Dictionaries ordinarily translate laïcité as "secularity" or "secularism" (the latter being the political system), although it is sometimes rendered in English as laicity or laicism by its opponents. While the term was first used with this meaning in 1871 in the dispute over the removal of religious teachers and instruction from elementary schools, the word laïcisme dates to 1842. In its strict and official acceptance, it is the principle of separation of church (or religion) and state. Etymologically, laïcité is a noun formed by adding the suffix -ité (English -ity, Latin -itās) to the Latin adjective lāicus, a loanword from the Greek λᾱϊκός (lāïkós "of the people", "layman"), the adjective from λᾱός (lāós "people"). French secularism has a long history. For the last century, the French government policy has been based on the 1905 French law on the Separation of the Churches and the State.

Types of Snow
Types of snow can be designated by the shape of its flakes, description of how it is falling, and by how it collects on the ground. A blizzard and snow storm indicate heavy snowfalls over a large area, snow squalls give heavy snowfalls over narrow bands, while flurries are used for the lightest snowfall. Types which fall in the form of a ball, rather than a flake, are known as graupel, with sleet and snow grains as types of graupel. Once on the ground, snow can be categorized as powdery when fluffy, granular when it begins the cycle of melting and refreezing, and crud or eventually ice once it packs down into a dense drift after multiple melting and refreezing cycles. When powdering, snow drifts with the wind or ground blizzard, sometimes to the depth of several metres. After attaching to hillsides, blown snow can evolve into a snow slab, which is an avalanche hazard on steep slopes.

Bamboo Node’s Vascular Bundle
The vascular bundle is an important structural unit that determines the growth and properties of bamboo. A high-resolution X-ray microtomography (μCT) was used to observe and reconstruct a three-dimensional (3D) morphometry model of the vascular bundle of the Qiongzhuea tumidinoda node due to its advantages of quick, nondestructive, and accurate testing of plant internal structure.
