Academic Tourism and Transport Services
Academic tourism is an important opportunity for the tourism industry and for the growth of academic knowledge. Thus, the continued growth of academic tourism has provided opportunities for tour operators, as well as for educational service providers, so that students have become a potential source of long-term investments for destinations. In addition, transport and mobility opportunities in tourist destinations are extremely relevant for academic tourism, especially as a result of the fact that transport can be considered as a primary factor in tourism. More specifically, the unavailability of transport will negatively affect the image of a particular tourist destination, which will, therefore, lead to a reduction in the likelihood that that destination will be visited again.

Fish Pond Water Quality
The spread of disease caused by the presence of bacteria, algae, protozoa, and fungi in a fish pond can cause biological pollution and reduce fish product production. Water can quickly lose its ability to support life, reproduction, waste excretion, growth, and feed the fish in fish ponds. The needs of the fish, the water quality, and factors for managing the water quality should be understood by those wishing to be successful fish farmers.

Cutibacterium acnes
Cutibacterium acnes is a member of the skin microbiota found predominantly in regions rich in sebaceous glands. It is involved in maintaining healthy skin and has long been considered a commensal bacterium. Its involvement in various infections has led to its emergence as an opportunist pathogen. Interactions between C. acnes and the human host, including the human skin microbiota, promote the selection of C. acnes strains capable of producing several virulence factors that increase inflammatory capability. This pathogenic property may be related to many infectious mechanisms, such as an ability to form biofilms and the expression of putative virulence factors capable of triggering host immune responses or enabling C. acnes to adapt to its environment. During the past decade, many studies have identified and characterized several putative virulence factors potentially involved in the pathogenicity of this bacterium. These virulence factors are involved in bacterial attachment to target cells, polysaccharide-based biofilm synthesis, molecular structures mediating inflammation, and the enzymatic degradation of host tissues. C. acnes, like other skin-associated bacteria, can colonize various ecological niches other than skin. It produces several proteins or glycoproteins that could be considered to be active virulence factors, enabling the bacterium to adapt to the lipophilic environment of the pilosebaceous unit of the skin, but also to the various organs it colonizes.

Constructed Wetland Components in Wastewater Treatment
An efficient approach to treating anthropogenic discharge (e.g., wastewater, effluents from agriculture and industry, stormwater runoff) is to create a constructed wetland (CW), which simulates natural marshland or swampland. These artificial wetlands employ physical, chemical, and/or biological methods, either consecutively or concurrently, to convert and extract different contaminants from the wastewater, and as such are highly intricate systems. Different system components of CWs, such as the porous bed, plants, and microorganisms, have contribution to the removal of phenols in wastewater treatment.

Magnesium and Stress
Magnesium deficiency and stress are both common conditions among the general population, which, over time, can increase the risk of health consequences.  Clinical and pre-clinical evidence suggest that stress could increase magnesium loss, causing a deficiency; and in turn, magnesium deficiency could enhance the body’s susceptibility to stress, resulting in a magnesium and stress vicious circle.

Knowledge Integration in Smart Factories
Knowledge integration is well explained by the human–organization–technology (HOT) approach known from knowledge management. This approach contains the horizontal and vertical interaction and communication between employees, human-to-machine, but also machine-to-machine. Different organizational structures and processes are supported with the help of appropriate technologies and suitable data processing and integration techniques. In a Smart Factory, manufacturing systems act largely autonomously on the basis of continuously collected data. The technical design concerns the networking of machines, their connectivity and the interaction between human and machine as well as machine-to-machine. Within a Smart Factory, machines can be considered as intelligent manufacturing systems. Such manufacturing systems can autonomously adapt to events through the ability to intelligently analyze data and act as adaptive manufacturing systems that consider changes in production, the supply chain and customer requirements. Inter-connected physical devices, sensors, actuators, and controllers form the building block of the Smart Factory, which is called the Internet of Things (IoT). IoT uses different data processing solutions, such as cloud computing, fog computing, or edge computing, to fuse and process data. This is accomplished in an integrated and cross-device manner.

Born Equal: Can Genetics Make the Perfect Athlete?
Thanks to the dawn of accessible science to map the human genome and the research that is poured into it, genetics are playing a larger role in elite sports. Genetics have a large influence over many attributes necessary for athletic excellence such as strength, muscle size, muscle fibre composition, anaerobic threshold, lung capacity, and flexibility. The aim of the study was to analyse a large database of athletes, comparing their chosen sports and the level that they play. Analysis of the individuals will include genotypes in six heavily studied genes attributed to athlete potential: ACTN3, MSTN, NOS3, ACE, AMPD1 and TRHR. A combination of both nurture and nature will always be required to bring the most out of an individual, however it would be naïve to ignore natural gifts. Genotypes may give an advantage to certain individuals but the lines between which genotype bring the most benefits is blurred, certain genotypes such as those found in MSTN are very uncommon but have very high affinity for power sports and bodybuilding. Other genes such as the once hailed “sports gene” ACTN3 have far more varied distribution and no particular athlete appeared to be hampered from any genotype, however the C allele did have affinity towards strength and power. From the six analysed genes in the study both power/strength athletes and bodybuilders had completed genotype affinity, however these genes seem to have less impact on those that compete in endurance/stamina sports. The  ACTN3 C allele, MSTN G allele, NOS3 T allele, ACE II, AMPD1 C allele and TRHR C allele all show affinity towards power, strength and/or bodybuilding athletes, only the NOS3 C allele showed a true affinity towards endurance/stamina sports.

Cybersecurity Frameworks and Information Security Standards
Businesses are reliant on data to survive in the competitive market, and data is constantly in danger of loss or theft. Loss of valuable data leads to negative consequences for both individuals and organizations. Cybersecurity is the process of protecting sensitive data from damage or theft. To successfully achieve the objectives of implementing cybersecurity at different levels, a range of procedures and standards should be followed. Cybersecurity standards determine the requirements that an organization should follow to achieve cybersecurity objectives and facilitate against cybercrimes. Cybersecurity standards demonstrate whether an information system can meet security requirements through a range of best practices and procedures. A range of standards has been established by various organizations to be employed in information systems of different sizes and types.

Rhinovirus
Rhinoviruses (RVs) are non-enveloped positive sense RNA viruses with a lifecycle fully contained within the cytoplasm. Despite decades of study, the details of how RVs exit the infected cell are still unclear. Current literature strongly suggests a role for necroptosis and/or autophagy in RV release, with the caveat that all the literature is based on RV-A and RV-B strains, with no studies to date examining the interaction of RV-C strains with cell death pathways.

Mitochondrial Metabolism of Fatty Acids
Mitochondria are the powerhouse of the cells, generating up to 90% of the energy within a cell in the form of adenosine triphosphate (ATP). There is a close connection between fatty acid metabolism and mitochondria, involving a considerable number of cellular processes that go well beyond mitochondrial fatty acid metabolism. Fatty acids are essential for ATP and energy production, and are therefore highly relevant in the regulation of energy homeostasis. The processes of β-oxidation, linked to ATP production, and mitochondrial fatty acid biosynthesis (mtFAS) are both localized in the mitochondria. This last pathway, in particular, produces molecules that are used as cellular structural components for post-translational modifications of proteins and in signaling cascades.

Solar Architecture in Energy Engineering
Solar Architecture represents the confluence of the two disciplines of energy engineering and architecture. The concept of Solar Architecture defines a decision-making process to select, design, deploy, and operate solar energy-enabled solutions for environments where solar energy resources are part of the energy mix. The principles of Solar Architecture include maximizing solar energy harvesting from solution’s surfaces with a positive balance of energy, carbon, and cost provided by the solution. Solar Architecture application selection is built on two major cornerstones, features and groups, defining the best options in energy engineering of a solar solution. Solar surfaces are key to solar architecture. They are the “heart”, and balance-of-system components are the “muscles” of solar solutions. Addressing energy losses in photovoltaic, solar to thermal, and solar to chemical energy conversion allows for increasing energy harvesting yield. Life Cycle Assessment and solar energy harvesting methodologies based on solar surface characteristics define Solar Architecture Balance. This balance allows for defining energy, carbon, and cost return on investment for solar solutions and selecting the best solution for related assets/environment.

Islamic Revival
Islamic revival (Arabic: تجديد tajdīd, lit., "regeneration, renewal"; also الصحوة الإسلامية aṣ-Ṣaḥwah l-ʾIslāmiyyah, "Islamic awakening") refers to a revival of the Islamic religion. The revivers are known in Islam as mujaddids. Within the Islamic tradition, tajdid has been an important religious concept, which has manifested itself throughout Islamic history in periodic calls for a renewed commitment to the fundamental principles of Islam and reconstruction of society in accordance with the Quran and the traditions of the Islamic prophet Muhammad (hadith). The concept of tajdid has played a prominent role in contemporary Islamic revival. In academic literature, "Islamic revival" is an umbrella term encompassing "a wide variety of movements, some intolerant and exclusivist, some pluralistic; some favorable to science, some anti-scientific; some primarily devotional, and some primarily political; some democratic, some authoritarian; some pacific, some violent". After the late 1970s, when the Iranian Revolution erupted, a worldwide Islamic revival emerged in response to the success of the revolution, owing in large part to the failures of secular Arab nationalism in the aftermath of the Six-Day War and the humiliation the ideology’s defeat in the war brought to the Muslim world, and popular disappointment with secular nation states in the Middle East and Westernized ruling elites, which had dominated the Muslim world during the preceding decades, and which were increasingly seen as authoritarian, ineffective and lacking cultural authenticity. Further motivation for the revival included the Lebanese Civil War, which began in 1975 and resulted in a level of sectarianism between Muslims and Christians previously unseen in many Middle Eastern countries. Another motivation was the newfound wealth and discovered political leverage brought to much of the Muslim world in the aftermath of the 1973 oil crisis and also the Grand Mosque seizure which occurred in late 1979 amidst the revival; both of these events encouraged the rise of the phenomenon of “Petro-Islam” in Saudi Arabia during the mid-to-late 1970s in an effort by the Saudi monarchy to counterbalance the consolidation of the Iranian Revolution, exporting neo-Wahhabi ideologies to many mosques worldwide. As such, it has been argued that with both of the Islamic superpowers in the Middle East (Iran and Saudi Arabia) espousing Islamist ideologies by the end of the 1970s, and the isolation of the traditionally secularist Egypt during the period from being the most influential Arab country as a result of the Camp David Accords- resulting in Saudi Arabia’s newfound dominance over Arab countries - the Islamic revival became especially potent amongst Muslims worldwide. With Lebanon, traditionally a source of secular Arab culture, fractured between Muslim and Christian, exposing the failures of its secular confessionalist political system, there was a general idea amongst many Muslims by the late 1970s that secularism had failed in the Middle East to deliver the demands of the masses. In Egypt, the revival was also motivated by the migration of many Egyptians during the 1980s to the Gulf countries in search of work; when they returned, returning especially in the aftermath of the Gulf War in Kuwait, they brought the neo-Wahhabist ideologies and more conservative customs of the Gulf back with them. Religiously, the revival was motivated by a desire to "restore Islam to ascendancy in a world that has turned away from God". This revival has been accompanied by growth of various reformist-political movements inspired by Islam (also called Islamist), and by "re-Islamisation" of society from above and below, with manifestations ranging from sharia-based legal reforms to greater piety and growing adoption of Islamic culture (such as increased attendance at Hajj) among the Muslim public. An especially obvious sign of the re-Islamisation of many Muslims was the rise of the hijab in the public space, when in previous decades it had largely been abandoned in some Middle Eastern countries, as well as the adoption of the previously-unknown niqab by women outside of Gulf countries. Among immigrants in non-Muslim countries, it includes a feeling of a "growing universalistic Islamic identity" or transnational Islam, brought on by easier communications, media and travel. The revival has also been accompanied by an increased influence of fundamentalist preachers and terrorist attacks carried out by some radical Islamist groups on a global scale. The revival, which erupted during at the end of the 1970s and continued throughout the 1980s, has gradually fizzled out in many countries, including Saudi Arabia and Sudan, and has come to be abandoned by many younger and disillusioned people in more Islamist societies such as Iran , Tunisia and Turkey - placing more younger people in these countries increasingly at odds with their government, with whom they associate the Islamic revival with the political authoritarianism of these countries with. However it has remained fairly strong in other countries, particularly Syria , Iraq, Afghanistan and in Sahel, as a result of the Arab Spring. Preachers and scholars who have been described as revivalists (Mujaddids) or mujaddideen, by differing sects and groups, in the history of Islam include Ahmad ibn Hanbal, Ibn Taymiyyah, Shah Waliullah Dehlawi, Ahmad Sirhindi, Ashraf Ali Thanwi, Muhammad ibn Abd al-Wahhab, and Muhammad Ahmad. In the 20th century, figures such as Sayyid Rashid Rida, Hassan al-Banna, Sayyid Qutb, Abul A'la Maududi, Malcolm X, and Ruhollah Khomeini, have been described as such, and academics often use the terms "Islamist" and "Islamic revivalist" interchangeably. Contemporary revivalist currents include Jihadism, which seeks to intellectually and militarily counter socially regressive post colonial rhetoric and influences; neo-Sufism, which cultivates Muslim spirituality; and classical fundamentalism, which stresses obedience to Sharia (Islamic law) and ritual observance.

Chitin
       Chitin, being the second most abundant biopolymer after next to cellulose, has been gaining popularity since its initial first discovery by Braconot in 1811. However, fundamental knowledge and literature on about chitin and its derivatives from insects are difficult to obtain. The most common and sought-after sources of chitin are shellfishes (especially crustaceans) and other aquatic invertebrates. The amount of shellfishes available is obviously restricted by the amount of food waste that is allowed; hence, it is a limited resource. Therefore,Hence, insects are the best choices since, out of 1.3 million species in the world, 900,000 are insects, making them the most abundant species in the world. In this review, a total of 82 samples from shellfishes—crustaceans and mollusks (n = 46), insects (n = 23), and others (n = 13)—have been collected and studied for their chemical extraction of chitin and its derivatives. The aim of this paper is to review the extraction method of chitin and chitosan for a comparison of the optimal demineralization and deproteinization processes with, so as to consideration of insects as alternative sources of chitin. The methods employed in this review are based on comprehensive bibliographic research. Based on previous data, chitin and chitosan yield contents of insects in their study favorably compares and competes with those of commercial chitin and chitosan—for example, 45% in Bombyx eri, 36.6% in Periostracum cicadae (cicada sloughs), and 26.2% in Chyrysomya megacephala. Therefore, according to the data reported by previous researchers, with comparable yield values to those of against crustacean chitin and the great interests of in insects as alternative sources, efforts towards comprehensive knowledge in this field are relevant.

Microcomputer Revolution
The microcomputer revolution (or personal computer revolution or digital revolution) is a phrase used to describe the rapid advances of microprocessor-based computers from esoteric hobby projects to a commonplace fixture of homes in industrial societies during the 1970s and 1980s. Prior to 1977, the only contact most of the population had with computers was through utility bills, bank and payroll services, or computer-generated junk mail. Within a decade, computers became common consumer goods. The advent of affordable personal computers has had lasting impact on education, business, music, social interaction, and entertainment.
