Domain Fronting
Domain fronting is a technique for Internet censorship circumvention that uses different domain names in different communication layers of an HTTPS connection to discreetly connect to a different target domain than is discernable to third parties monitoring the requests and connections. Due to quirks in security certificates, the redirect systems of the content delivery networks (CDNs) used as 'domain fronts', and the protection provided by HTTPS, censors are typically unable to differentiate circumvention ("domain-fronted") traffic from overt non-fronted traffic for any given domain name. As such they are forced to either allow all traffic to the domain front—including circumvention traffic—or block the domain front entirely, which may result in expensive collateral damage and has been likened to "blocking the rest of the Internet".[note 1] Domain fronting does not conform to HTTP standards that require the SNI extension and HTTP Host header to contain the same domain. Large cloud service providers, including Amazon and Google, now actively prohibit domain fronting, which has made it "largely non-viable"[note 1] as a censorship bypass technique.

Digital Image Watermarking Techniques
Image authentication is an extremely significant concern for the digital revolution, as it is easy to alter any image. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Based on the desired applications, several suitable watermarking techniques have been developed to mitigate this concern. However, it is tough to achieve a watermarking system that is simultaneously robust and secure. This paper gives details of standard watermarking system frameworks and lists some standard requirements that are used in designing watermarking techniques for several distinct applications. The current trends of digital image watermarking techniques are also reviewed to find state-of-the-art methods and their limitations. Some conventional attacks are discussed, and future research directions are given.

Effects of Pornography on Relationships
Many individuals perceive pornography to have a negative effect on interpersonal relationships, satisfaction, and sexual functioning; however, findings on the topic are mixed. Pornography has never been so widely and universally accessible as it is today. As such, the consumption of pornography is on the rise, for both men and women. This unlimited access changes not only how individuals consume pornography, but how pornography can affect individuals and relationships. Pornography can impact many aspects of an individual’s life, and it is important to understand just what these effects are, as well as the extent to which these effects can reach.

Idolatry in Sikhism
Sikhism prohibits idolatry, in accordance with mainstream Khalsa norms and the teachings of the Sikh Gurus, a position that has been accepted as orthodox. Growing Sikh popular discontent with Gurdwara administration and practices during the 1800s, revivalist movements in the mid-1800s who opposed idol worship like the Nirankaris and the Namdharis (who however have followed a living guru since its inception), and the encroachment of Brahmanical customs in the Golden Temple during that period, led to the establishment of the Singh Sabha Movement in 1873, in which the Tat Khalsa faction, dominant since the early 1880s, pushed to renew and standardize the practice of Sikhism. After a period of political advancement, the Khalsa faction re-established direct control over Gurdwara management over the Udasi and Hindu mahants, who institutionalized idol worship and would eventually identify with the Sanatan Sikhs, who identified with the Brahmanical social structure and considered idol worship as not harmful. The mahants had gained control of Gurdwaras after heavy Mughal persecution forced the Khalsa to relinquish control of the Gurdwaras and vacate the Punjab plains in the 1700s; they were most prominent in the 1800s. The Arya Samaj, opponents of the Sikhs, asserted that many Sikhs accepted idols and their worship within Sikh temples, unlike Khalsa Sikhs who strongly opposed the practice. In 1905, after re-establishing institutional control, the Khalsa managed to have removed the idols installed during the preceding period, as well as ending mahant administration and the practice of other non-Sikh, Brahmanical rituals in the process, considering them "Hindu accretions" and "Brahmanical stranglehold," amidst a major controversy within the Sikh community of that era. The prohibition, state Fenech and McLeod, has also served a means to assert Sikhism differs from Hinduism.

Revitalization of Fishing Village Tourism
Fishing villages and oceans offer various resources and include excellent natural environments and unique cultures that can make such villages attractive spaces to meet the health, culture, and environmental needs of individuals. However, as society has developed and the environment has changed, the catch, which is the major source of income in fishing villages, has declined significantly worldwide, making it difficult to address regional economic issues. Fishing villages that have lost their ability to survive are gradually facing extinction, and there are real problems linked to the survival of fishing communities. Rural areas, in a similar manner to fishing villages, are incorporating tourism in regional development in an attempt to solve the crisis of agriculture, which has itself lost the ability to support entire villages. As a result, tourism has come to be recognized as a representative means of revitalizing rural areas.

Lignocellulosic biomass (LC biomass)
      Bioenergy represents energy from biomass and plays an important role in promoting renewable alternatives. LC biomass is one of the most generous renewable bioresources in nature containing lignin, cellulose, and hemicelluloses. Lignocellulosic materials are the best sources used for biofuel production, such as biogas, and include residues from agriculture and forests, energy crops, and municipal and food waste. According to the latest statistical report for biogas, in Europe, almost 72% of the feedstocks used in the anaerobic digestion (AD) process for biogas production come from the agricultural sector, such as energy crops, manure, and other agricultural residues. The main issue of using lignocellulosic (LC) biomass for the biogas production is biomass recalcitrance, which represents biomass resistance to chemical and biological breakdown.

Mechanism of seed anaerobic germination
As sessile organisms, flooding/submergence is one of the major abiotic stresses for higher plants, with deleterious effects on their growth and survival. Therefore, flooding/submergence is a large challenge for agriculture in lowland areas worldwide. Long-term flooding/submergence can cause severe hypoxia stress to crop plants and can result in substantial yield loss. Rice has evolved distinct adaptive strategies in response to low oxygen (O2) stress caused by flooding/submergence circumstances. Recently, direct seeding practice has been increasing in popularity due to its advantages of reducing cultivation cost and labor. However, establishment and growth of the seedlings from seed germination under the submergence condition are large obstacles for rice in direct seeding practice. The physiological and molecular regulatory mechanisms underlying tolerant and sensitive phenotypes in rice have been extensively investigated. Here, this review focuses on the progress of recent advances in the studies of the molecular mechanisms and metabolic adaptions underlying anaerobic germination (AG) and coleoptile elongation. Further, we highlight the prospect of introducing quantitative trait loci (QTL) for AG into rice mega varieties to ensure the compatibility of flooding/submergence tolerance traits and yield stability, thereby advancing the direct seeding practice and facilitating future breeding improvement.

The Reverend
The Reverend is an honorific style most often placed before the names of Christian clergy and ministers. There are sometimes differences in the way the style is used in different countries and church traditions. The Reverend is correctly called a style but is often and in some dictionaries called a title, form of address or title of respect. The style is also sometimes used by leaders in non-Christian religions such as Judaism and Buddhism. The term is an anglicisation of the Latin reverendus, the style originally used in Latin documents in medieval Europe. It is the gerundive or future passive participle of the verb revereri ("to respect; to revere"), meaning "[one who is] to be revered/must be respected". The Reverend is therefore equivalent to The Honourable or The Venerable. It is paired with a modifier or noun for some offices in some religious traditions: Anglican archbishops and most Roman Catholic bishops are usually styled The Most Reverend (reverendissimus); other Anglican bishops and some Roman Catholic bishops are styled The Right Reverend; some Reformed churches have used The Reverend Mister as a style for their clergy. With Christian clergy, the forms His Reverence and Her Reverence is also sometimes used, along with its parallel in direct address, Your Reverence. The abbreviation HR is sometimes used.

Seaweeds in Producing Safe and Sustainable Bio-Packaging
Diverse studies demonstrate that seaweed polysaccharides (e.g., alginates and carrageenans) not only provide health benefits, but also contribute to the production of biopolymeric film and biodegradable packaging. The dispersion of plastics and microplastics in the oceans provoke serious environmental issues that influence ecosystems and aquatic organisms. Thus, the sustainable use of seaweed-derived biopolymers is now crucial to replace plasticizers with biodegradable materials, and thus preserve the environment.

Panj Takht
A takht, or taḵẖata (Punjabi: ਤਖ਼ਤ) literally means a throne or seat of authority and is a spiritual and temporal centre of Sikhism. There are five Takhts, which are five gurudwaras that have a very special significance for the Sikh community. The first and the most important was established by Guru Hargobind in 1609, 'Akal Takht' (the Throne of the Timeless God) and is just opposite the gate of Harmandir Sahib – The Golden Temple, Amritsar. While the Harmandir Sahib, or Golden Temple, represents Sikh spiritual guidance, the Akal Takht symbolizes the dispensing of justice and temporal activity. It is the highest seat of temporal authority of the Khalsa and the seat of the Sikh religion's earthly authority. There, the Guru held his court and decided matters of military strategy and political policy. Later on, the Sikh Nation (Sarbat Khalsa) took decisions here on matters of peace and war and settled disputes between the various Sikh groups. The Sarangi singers sung the ballads of the Sikh Gurus and warriors at the place and robes of honour (saropas) were awarded to persons who rendered distinguished services of the community of men in general. In December 2010, the Deccan Odyssey train, taken on charter from Government of Maharashtra, started with the aim to have a journey across four Sikh takhts, with a flight by devout and sightseers to the fifth takht (Takht Sri Patna Sahib). A special train named Panj Takht Special train for the pilgrimage of five Sikh takhts, was flagged off on 16 February 2014.

Out-of-Autoclave Process for Composite Manufacturing
Composite materials have gained increased usage due to their unique characteristic of a high-stiffness-to-weight ratio. High-performing composite materials are produced in the autoclave by applying elevated pressure and temperature. The process is characterized by numerous disadvantages, such as long cycle time, massive investment, costly tooling, and excessive energy consumption. As a result, composite manufacturers seek a cheap alternative to reduce cost and increase productivity. The out-of-autoclave (OoA) process manufactures composites by applying vacuum, pressure, and heat outside of the autoclave.

Genetic Use Restriction Technologies
Genetic use restriction technologies (GURTs), developed to secure return on investments through protection of plant varieties, are among the most controversial and opposed genetic engineering biotechnologies as they are perceived as a tool to force farmers to depend on multinational corporations’ seed monopolies.  This led to a de facto global moratorium on this technology, which is still far from being withdrawn.
