Fish Pathology
One of the main constraints in aquaculture production is farmed fish vulnerability to diseases due to husbandry practices or external factors like pollution, climate changes, or even the alterations in the dynamic of product transactions in this industry. It is though important to better understand and characterize the intervenients in the process of a disease outbreak as these lead to huge economical losses in aquaculture industries. High-throughput technologies like proteomics can be an important characterization tool especially in pathogen identification and the virulence mechanisms related to host-pathogen interactions on disease research and diagnostics that will help to control, prevent, and treat diseases in farmed fish. Proteomics' important role is also maximized by its holistic approach to understanding pathogenesis processes and fish responses to external factors like stress or temperature making it one of the most promising tools for fish pathology research.

Western European Colonialism and Colonization
File:SierraLeoneHofstra3.1.tiff European colonialism and colonization was the policy or practice of acquiring full or partial political control over other societies and territories, creating a colony, occupying it with settlers, and exploiting it economically. Research suggests, the current conditions of postcolonial countries have roots in colonial actions and policies. For example, colonial policies, such as the type of rule implemented, the nature of investments, and identity of the colonizers, are cited as impacting postcolonial states. Examination of the state-building process, economic development, and cultural norms and mores shows the direct and indirect consequences of colonialism on the postcolonial states.

Spilled Oil in Marine Environment
Oil spill is a widespread environmental problem with significant ecological impacts. When oil is spilled in the sea,  it undergoes different  degradation processes such as dispersion, photooxidation, evaporation, dissolution, emulsion, biodegradation and other weathering processes. The most important among these processes is biodegradation, which is facilitated by naturally occurring oil-degrading bacteria.  The interaction of bacteria with hydrocarbons in oil is affected by different environmental factors.  Several studies have evaluated the effects of each factor on the biodegradation of the oil by bacterial, but none has taken all these factors together.

Republic
A republic (Latin: res publica, meaning "public affair") is a form of government in which the country is considered a "public matter", not the private concern or property of the rulers. The primary positions of power within a republic are attained, through democracy, oligarchy, or a mix thereof, rather than being unalterably occupied. It has become the opposing form of government to a monarchy and has therefore no monarch as head of state. (As of 2017), 159 of the world's 206 sovereign states use the word "republic" as part of their official names – not all of these are republics in the sense of having elected governments, nor is the word "republic" used in the names of all nations with elected governments. The word republic comes from the Latin term res publica, which literally means "public thing", "public matter", or "public affair" and was used to refer to the state as a whole. The term developed its modern meaning in reference to the constitution of the ancient Roman Republic, lasting from the overthrow of the kings in 509 BC to the establishment of the Empire in 27 BC. This constitution was characterized by a Senate composed of wealthy aristocrats and wielding significant influence; several popular assemblies of all free citizens, possessing the power to elect magistrates and pass laws; and a series of magistracies with varying types of civil and political authority. Most often a republic is a single sovereign state, but there are also sub-sovereign state entities that are referred to as republics, or that have governments that are described as "republican" in nature. For instance, Article IV of the United States Constitution "guarantee[s] to every State in this Union a Republican form of Government". Another example is the Soviet Union which described itself as being a group of "Soviet Socialist Republics", in reference to the 15 individually federal, multinational, top-level subdivisions or republics. In the context of American constitutional law, the definition of republic refers specifically to a form of government in which elected individuals represent the citizen body and exercise power according to the rule of law under a constitution, including separation of powers with an elected head of state, referred to as a constitutional republic or representative democracy.

Lysenkoism
Lysenkoism (Russian: Лысенковщина, romanized: Lysenkovshchina, [ɫɨˈsɛnkəfɕːʲɪnə], Ukrainian: лисенківщина, Template:IPA-uk) was a political campaign led by Trofim Lysenko against genetics and science-based agriculture in the mid-20th century, rejecting natural selection in favour of a form of Lamarckism, as well as expanding upon the techniques of vernalization and grafting. In time, the term has come to be identified as any deliberate distortion of scientific facts or theories for purposes that are deemed politically, religiously or socially desirable. More than 3,000 mainstream biologists were dismissed or imprisoned, and numerous scientists were executed in the campaign to suppress scientific opponents. The president of the Agriculture Academy, Nikolai Vavilov, who had been Lysenko's mentor, but later denounced him, was sent to prison and died there, while Soviet genetics research was effectively destroyed. Research and teaching in the fields of neurophysiology, cell biology, and many other biological disciplines were harmed or banned. Other countries of the Eastern Bloc including the People's Republic of Poland, the Republic of Czechoslovakia, and the German Democratic Republic accepted Lysenkoism as the official "new biology", to varying degrees, as did the People's Republic of China for some years. The government of the USSR supported the campaign, and Joseph Stalin personally edited a speech by Lysenko in a way that reflected his support for what would come to be known as Lysenkoism, despite his skepticism toward Lysenko's assertion that all science is class-oriented in nature. Lysenko served as the director of the Soviet Union's Lenin All-Union Academy of Agricultural Sciences.

Liberation Theology
Liberation theology is a synthesis of Christian theology and Marxist socio-economic analyses that emphasizes social concern for the poor and the political liberation for oppressed peoples. In the 1950s and the 1960s, liberation theology was the political praxis of Latin American theologians, such as Gustavo Gutiérrez of Peru, Leonardo Boff of Brazil, Juan Luis Segundo of Uruguay, and Jon Sobrino of Spain, who popularized the phrase "Preferential option for the poor". The Latin American context also produced Evangelical advocates of liberation theology, such as C. René Padilla of Ecuador, Samuel Escobar of Peru, and Orlando E. Costas of Puerto Rico, who, in the 1970s, called for integral mission, emphasizing evangelism and social responsibility. Theologies of liberation have developed in other parts of the world such as Black theology in the United States and South Africa , Palestinian liberation theology, Dalit theology in India , and Minjung theology in South Korea .

Tuskegee Syphilis Experiment
The Tuskegee Study of Untreated Syphilis in the African American Male was a clinical study conducted between 1932 and 1972 by the United States Public Health Service. The purpose of this study was to observe the natural history of untreated syphilis; the African-American men in the study were only told they were receiving free health care from the Federal government of the United States. The Public Health Service started the study in 1932 in collaboration with Tuskegee University (then the Tuskegee Institute), a historically black college in Alabama. Investigators enrolled in the study a total of 600 impoverished, African-American sharecroppers from Macon County, Alabama. Of these men, 399 had latent syphilis, with a control group of 201 men who were not infected. As an incentive for participation in the study, the men were promised free medical care, but were deceived by the PHS, who disguised placebos, ineffective methods, and diagnostic procedures as treatment. The men who had syphilis were never informed of their diagnosis, despite the risk of infecting others, and the fact that the disease could lead to blindness, deafness, mental illness, heart disease, bone deterioration, collapse of the central nervous system, and death.. According to the Centers for Disease Control and Prevention, the men were told that they were being treated for "bad blood,” a colloquialism that described various conditions such as syphilis, anemia and fatigue. "Bad blood"—specifically the collection of illnesses the term included—was a leading cause of death within the southern African-American community. The men were initially told that the study was only going to last six months, but it was extended to 40 years. After funding for treatment was lost, the study was continued without informing the men that they would never be treated. None of the infected men were treated with penicillin despite the fact that by 1947, the antibiotic had become the standard treatment for syphilis. Study clinicians could have chosen to treat all syphilitic subjects and close the study, or split off a control group for testing with penicillin. Instead, they continued the study without treating any participants; they withheld treatment and information about it from the subjects. In addition, scientists prevented participants from accessing syphilis treatment programs available to other residents in the area. The study continued, under numerous Public Health Service supervisors, until 1972, when a leak to the press resulted in its termination on November 16 of that year. The victims of the study, all African-American, included numerous men who died of syphilis, 40 wives who contracted the disease and 19 children born with congenital syphilis. The 40-year Tuskegee Study of Untreated Syphilis in the African American Male study was a major violation of ethical standards. Researchers knowingly failed to treat participants appropriately after penicillin was proven to be an effective treatment for syphilis and became widely available. Moreover, participants remained ignorant of the study clinicians’ true purpose, which was to observe the natural course of untreated syphilis. The revelation in 1972 of study failures by a whistleblower, Peter Buxtun, led to major changes in U.S. law and regulation concerning the protection of participants in clinical studies. Now studies require informed consent, communication of diagnosis and accurate reporting of test results. The Tuskegee Syphilis Study, cited as "arguably the most infamous biomedical research study in U.S. history," led to the 1979 Belmont Report and to the establishment of the Office for Human Research Protections (OHRP). It also led to federal laws and regulations requiring institutional review boards for the protection of human subjects in studies involving them. The OHRP manages this responsibility within the United States Department of Health and Human Services (HHS). On May 16, 1997, President Bill Clinton formally apologized on behalf of the United States to victims of the study.

Heteroaromatic Diazirines in Material and Medicinal Chemistry
In materials (polymer) science and medicinal chemistry, heteroaromatic derivatives play the role of the central skeleton in development of novel devices and discovery of new drugs. On the other hand, (3-trifluoromethyl)phenyldiazirine (TPD) is a crucial chemical method for understanding biological processes such as ligand–receptor, nucleic acid–protein, lipid–protein, and protein–protein interactions. In particular, use of TPD has increased in materials science to create novel electric and polymer devices with comparative ease and reduced costs. Therefore, a combination of heteroaromatics and (3-trifluoromethyl)diazirine is a promising option for creating better materials and elucidating the unknown mechanisms of action of bioactive heteroaromatic compounds.

Adaptive Clustering
The paper is devoted to an overview of multi-agent principles, methods, and technologies intended to adaptive real-time data clustering. The proposed methods provide new principles of self-organization of records and clusters, represented by software agents, making it possible to increase the adaptability of different clustering processes significantly. The paper also presents a comparative review of the methods and results recently developed in this area and their industrial applications. An ability of self-organization of items and clusters suggests a new perspective to form groups in a bottom-up online fashion together with continuous adaption previously obtained decisions. Multi-agent technology allows implementing this methodology in a parallel and asynchronous multi-thread manner, providing highly flexible, scalable, and reliable solutions. Industrial applications of the intended for solving too complex engineering problems are discussed together with several practical examples of data clustering in manufacturing applications, such as the pre-analysis of customer datasets in the sales process, pattern discovery, and ongoing forecasting and consolidation of orders and resources in logistics, clustering semantic networks in insurance document processing. Future research is outlined in the areas such as capturing the semantics of problem domains and guided self-organization on the virtual market.

Ottoman Decline Thesis
The Ottoman decline thesis or Ottoman decline paradigm (Turkish: Osmanlı Gerileme Tezi) is an obsolete historical narrative which once played a dominant role in the study of the history of the Ottoman Empire. According to the decline thesis, following a golden age associated with the reign of Sultan Suleiman the Magnificent (r. 1520–1566), the empire gradually entered into a period of all-encompassing stagnation and decline from which it was never able to recover, lasting until the dissolution of the Ottoman Empire in 1923. This thesis was used throughout most of the twentieth century as the basis of both Western and Republican Turkish understanding of Ottoman history. However, by 1978, historians had begun to reexamine the fundamental assumptions of the decline thesis. After the publication of numerous new studies throughout the 1980s, 1990s, and 2000s, and the reexamination of Ottoman history through the use of previously untapped sources and methodologies, academic historians of the Ottoman Empire achieved a consensus that the entire notion of Ottoman decline was a myth – that in fact, the Ottoman Empire did not stagnate or decline at all, but rather continued to be a vigorous and dynamic state long after the death of Suleiman the Magnificent. The decline thesis has been criticized as "teleological", "regressive", "Orientalist", "simplistic", and "one-dimensional", and described as "a concept which has no place in historical analysis". Scholars have thus "learned better than to discuss [it]." Despite this dramatic paradigm shift among professional historians, the decline thesis continues to maintain a strong presence in popular history, as well as academic history written by scholars who are not specialists on the Ottoman Empire. In some cases this is due to the continued reliance by non-specialists on outdated and debunked works, and in others to certain political interests benefiting from the continued perpetuation of the decline narrative.

List of Meteor Air Bursts
Many explosions recorded in Earth's atmosphere are likely to be caused by the air bursts that result from meteors exploding as they hit the thicker part of the atmosphere. These types of meteors are also known as fireballs or bolides with the brightest known as superbolides. Before entering Earth's atmosphere, these larger meteors were originally asteroids and comets of a few to several tens of metres in diameter, contrasting with the much smaller and much more common "shooting stars". The most powerful recorded air burst is the 1908 Tunguska event. Extremely bright fireballs traveling across the sky are often witnessed from a distance, such as the 1947 Sikhote-Alin meteor and the 2013 Chelyabinsk meteor, both in Russia. If the bolide is large enough, fragments may survive such as the Chelyabinsk meteorite. Modern developments in infrasound detection by the Comprehensive Nuclear-Test-Ban Treaty Organization and infrared Defense Support Program satellite technology have increased the likelihood of detecting airbursts.

Odor Compounds in Meat
The volatile composition and odor of meat and meat products is based on the precursors present in the raw meat. These are influenced by various pre-slaughter factors (species, breed, sex, age, feed, muscle type). Furthermore, post-mortem conditions (chiller aging, cooking conditions, curing, fermentation, etc.) determine the development of meat volatile organic compounds (VOCs).
