Leprechaun
A leprechaun (Irish: leipreachán/luchorpán) is a type of fairy of the Aos Sí in Irish folklore. They are usually depicted as little bearded men, wearing a coat and hat, who partake in mischief. They are solitary creatures who spend their time making and mending shoes and have a hidden pot of gold at the end of the rainbow. If captured by a human, they often grant three wishes in exchange for their freedom. Like other Irish fairies, leprechauns may be derived from the Tuatha Dé Danann. Leprechaun-like creatures rarely appear in Irish mythology and only became prominent in later folklore.

Inhabited Institutionalism
Inhabited Institutionalism is a meso-level theoretical approach for evaluating the recursive relationships among institutions, social interactions, and organizations. This theoretical framework offers organizational scholars a multi-faceted consideration of coupling configurations that highlight how institutional processes are maintained, challenged, and transformed without reverting to nested yet binary arguments about individual agency and structural conditions.

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.

The Festival of Diwali: Its Origins and History
Diwali, the Festival of Lights, is one of India's most celebrated festivals, marked by joy, light, and a spirit of togetherness. Originating in ancient India, Diwali has grown beyond its religious roots to become a global celebration symbolizing victory over darkness, ignorance, and evil. While traditionally associated with Hinduism and stories from the Ramayana, Diwali is also celebrated by Sikhs, Jains, and Buddhists, each community attaching its own significance and narratives to the festivities. This article traces the historical evolution of Diwali from its origins in agrarian societies to its current standing as a multicultural and global festival. It examines the religious and cultural stories associated with Diwali, the rituals and customs observed across different communities, and the festival’s role in fostering social cohesion. As Diwali has spread globally, it has taken on new meanings and variations, demonstrating the enduring appeal of this ancient festival in modern times.

Silicon Micro-Strip Detectors
Silicon micro-strip detectors are fundamental tools for the high energy physics. Each detector is formed by a large set of parallel narrow strips of special surface treatments (diode junctions) on a slab of very high quality silicon crystals. Their development and use required a large amount of work and research. A very synthetic view is given of these important components and of their applications. Some details are devoted to the basic subject of the track reconstruction in silicon strip trackers. Recent demonstrations substantially modified the usual understanding of this argument.

Salt Bridges investigated by NMR
Salt bridges are interactions, electrostatic combined with hydrogen bonding, between oppositely charged residues, typically carboxylic acid anions and ammonium ions, provided they are close together.  For an illustration see Fig. 1. Salt bridges are of particular interest in proteins and other biomolecules.  In the present contribution salt bridges are investigated by means of 1H chemical shifts, determination of pKa values and deuterium isotope effect on 15N and 1H chemical shifts.  In the latter case model compounds like ammonium ions are also investigated and the use of deuterium isotope effects on chemical shifts are supported by Density Functional Theory (DFT) calculations.  The use of isotope effects on chemical shifts enables a distinction between salt bridges observed in the solid state by X-ray diffraction and those actually present in solution.

Areal Density (Computer Storage)
Areal density is a measure of the quantity of information bits that can be stored on a given length of track, area of surface, or in a given volume of a computer storage medium. Generally, higher density is more desirable, for it allows more data to be stored in the same physical space. Density therefore has a direct relationship to storage capacity of a given medium. Density also generally affects the performance within a particular medium, as well as price.

Fundamentals of the Electroreduction of CO2
Carbon dioxide (CO2) is one of the main greenhouse gases and the major factor driving global climate change. From the viewpoint of abundance, economics, non-toxicity, and renewability, CO2 is an ideal and significant C1 resource, and its capture and recycling into fuels and chemical feedstocks using renewable energy is of great significance for the sustainable development of society. Electrochemical CO2 reduction reactions (CO2RRs) are an important pathway to utilize CO2 resources. Zinc has been demonstrated as an effective catalyst for CO2RRs.

Dowel-Type Joints in Timber Structures
Dowel-type joints are one of the most common connectors. They basically consist of one or more cylindrical steel dowels inserted into aligned holes of different elements. The dowels transmit loads between the elements, being subjected to opposite compressive forces on the contact area with each element. This causes the dowels to work under bending moments and shear forces. There is an almost infinite number of possible configurations for dowel-type joints.

Power-System Protection
Power-system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the disconnection of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components that are under fault, whilst leaving as much of the network as possible still in operation. Thus, protection schemes must apply a very pragmatic and pessimistic approach to clearing system faults. The devices that are used to protect the power systems from faults are called protection devices.

Fungal Secondary Metabolism
Fungal secondary metabolites (SMs) comprise a vast collection of compounds expendable for these organisms under laboratory conditions. They exhibit enormous chemical diversity, and usually belong to four major families: terpenoids, polyketides, non-ribosomal peptides, or a combination of the last two. Their functions are very diverse and are normally associated with a greater fitness of the producing fungi in their environment, which often compete with other microorganisms or interact with host plants. Many SMs have beneficial applications, e.g., as antibiotics or medical drugs, but others, known as mycotoxins, are harmful to health.

Types of Electrochemical Energy Storage Devices
Researchers are increasingly paying attention to sustainable methods for storing energy. Many researchers are now concentrating their efforts on the development and exploration of novel materials for use in energy storage devices due to the limited supply of existing energy sources such as oil, coal, and natural gas, and escalating regional tensions. Because of these issues, sustainable renewable energy sources have been touted as an alternative to nonrenewable fuels. Deployment of renewable energy sources requires efficient and reliable energy storage devices due to their intermittent nature. High-performance electrochemical energy storage technologies with high power and energy densities are heralded to be the next-generation storage devices. Transition metal chalcogenides (TMCs) have sparked interest among electrode materials because of their intriguing electrochemical properties.

Plant-Based Milk Production
Growing concerns about the environmental impacts, healthiness, and ethical implications of eating animal-based products, such as meat, eggs, and milk, has led to an increase in demand for plant-based alternatives.  Plant-based milk substitutes can be created using two main approaches. First, certain oil-rich plant tissues (such as almonds, cashews, coconut flesh, flaxseeds, or soy beans) can be converted into colloidal suspensions using size-reduction and isolation techniques (such as soaking, grinding, enzyme-treatment, filtration, and centrifugation).  Second, plant-based oils (such as corn, flaxseed soybean, or sunflower oil) can be homogenized with water in the presence of plant-based proteins (such as pea, legume, or soy proteins), polysaccharides (gum arabic or beet pectin), phospholipids (such as soy or sunflower lecithin), or saponins (such as quillaja saponin) to create an oil-in-water emulsion with similar characteristics to bovine milk.

Charivari
Charivari, shivaree, chivaree, or skimmington (ride) was a folk custom in which a mock parade was staged through a community accompanied by a discordant mock serenade. Since the crowd aimed to make as much noise as possible by beating on pots and pans or anything that came to hand these parades are often referred to as rough music. Parades were of three types. In the first, and generally most violent form, a wrongdoer or wrongdoers might be dragged from their home or place of work and paraded by force through a community. In the process they were subject to the derision of the crowd, they might be pelted and frequently a victim or victims were dunked at the end of the proceedings. A safer form involved a neighbour of the wrongdoer impersonating the victim whilst being carried through the streets. The impersonator was obviously not himself punished and he often cried out or sang ribald verses mocking the wrongdoer. In the common form, an effigy was employed instead, abused and often burnt at the end of the proceedings. Communities used "rough music" to express their disapproval of different types of violation of community norms. For example, they might target marriages of which they disapproved such as a union between an older widower and much younger woman, or the too early remarriage by a widow or widower. Villages also used charivari in cases of adulterous relationships, against wife beaters, and unmarried mothers. It was also used as a form of shaming upon husbands who were beaten by their wives and had not stood up for themselves. In some cases, the community disapproved of any remarriage by older widows or widowers. Charivari is the original French word, and in Canada it is used by both English and French speakers. Chivaree became the common variant in Ontario, Canada. In the United States, the term shivaree is more common. As species of popular justice rituals Charivaric events were carefully planned and they were often staged at times of traditional festivity thereby blending delivering justice and celebration.
