English for Specific Purposes
English for Specific Purposes (ESP) is, undeniably, more challenging because it deals with the terms and jargon of the English language for a particular context. For instance, learning medical words in English requires specific vocabulary, which might not be part of common ESL. Despite learning ESL since a young age, most learners still face difficulties grasping the language, even more so for ESP learning.

Green Onion: Food, Nutritional and Therapeutic Significance
Nutrients are essential for the survival and proper functioning of all living organisms. These chemical compounds, mainly vitamins and minerals, serve as the building blocks and catalysts for various physiological processes within the body. To ensure that the body receives an adequate supply of these nutrients, maintaining a well-balanced diet is crucial. Balanced diets, encompassing a range of food groups, offer a unique set of nutrients necessary for optimal health and bodily function. Green onions are an important source of many essential nutrients, offering a rich array of vitamins, minerals, dietary fiber, proteins, carbohydrates and phytochemicals in various culinary dishes. Whereas macronutrients, encompassing proteins, carbohydrates and fats, represent the foremost sources of energy in the human body and are involved in various metabolism processes, micronutrients (minerals and vitamins) play critical cellular functions, serving as important antioxidants and participating in diverse enzymatic reactions. These nutrients contribute to the overall well-being of individuals, aiding in the maintenance of proper bodily functions and the prevention of nutritional deficiencies.

Indoor Positioning System
The indoor positioning system (IPS) provides continuous real-time localization of objects or people within an enclosed space in different environments, using a network of transmitters and receivers. Indoor localization is more complex than outdoor localization because the indoor communication channel varies significantly with the environment and depends heavily on many factors, such as building structure, room layout, and construction materials.

Theoretical Background of Explainable Artificial Intelligence
Artificial intelligence (AI) and machine learning (ML) have recently been radically improved and are now being employed in almost every application domain to develop automated or semi-automated systems. To facilitate greater human acceptability of these systems, explainable artificial intelligence (XAI) has experienced significant growth over the last couple of years with the development of highly accurate models but with a paucity of explainability and interpretability. XAI methods are mostly developed for safety-critical domains worldwide, deep learning and ensemble models are being exploited more than other types of AI/ML models, visual explanations are more acceptable to end-users and robust evaluation metrics are being developed to assess the quality of explanations.

Graeco-Latin Square
In combinatorics, a Graeco-Latin square or Euler square or pair of orthogonal Latin squares of order n over two sets S and T, each consisting of n symbols, is an n×n arrangement of cells, each cell containing an ordered pair (s,t), where s is in S and t is in T, such that every row and every column contains each element of S and each element of T exactly once, and that no two cells contain the same ordered pair. The arrangement of the s-coordinates by themselves (which may be thought of as Latin characters) and of the t-coordinates (the Greek characters) each forms a Latin square. A Graeco-Latin square can therefore be decomposed into two "orthogonal" Latin squares. Orthogonality here means that every pair (s, t) from the Cartesian product S×T occurs exactly once.

Criticisms of Electoral Politics
This article discusses criticisms of political systems, specifically representative democracy and direct democracy, that use elections as a tool for selecting representatives and/or deciding policy through a formal voting process as well as the act of voting itself. While representative democracy (and electoral systems in general) have become the modern civics global-standard, many of the below criticisms describe alternatives that existed before and/or independently of electoral systems. This includes but is not limited to the actions and political movements that stem from anti-electoralism, which describes activism around encouraging people not to vote for ethical or ideological reasons. It is also important to differentiate between criticisms of representative government and elections. Several of the following criticisms can be applied to both; however, the election of representatives and the consequences of the process on accountability of elected officials are the main focuses. This article does not address criticisms of neither "electoralism", the term coined by Terry Karl nor voter suppression, which is the act of discouraging or preventing people from voting in order to influence the outcome of an election in your favor. Criticisms of electoral politics range from cons of specific electoral mechanisms such as legislating by elected officials, initiative, referendum and recall to theoretical opposition to voting. These criticisms are relevant to discussions around electoral reform in both democratizing countries in the less developed world as well as most developed countries that espouse some form of electoral democracy.

Metallurgical Technologies to Treat E-Waste
e-waste is any broken/unwanted electrical and electronic equipment (EEE) that has reached the end of its lifecycle or economic life span. E-waste has been traditionally treated with metallurgical technologies such as mechanical separations, pyro-metallurgical, and hydrometallurgical methods. The technologies such as the pyro-metallurgical process to treat e-waste has been studied and linked with environmental challenges such as the generation of large quantities of harmful by-products, the formation of brominated and chlorinated di-benzo furans, and dioxins from halogens present in the plastic part of e-waste during the burning process. The pyro-metallurgical process requires high-energy to treat e-waste and is inefficient in the recovery of precious metals. Hydrometallurgical technology has also been explored, mostly involving chemical reagents such as strong acids (sulphuric acid, nitric acid, hydrochloric acid) and complex chemical reagents such as cyanide and thiosulfate to leach base, rare earth, and precious metals.

Melatonin and Liver Cancer
Melatonin (N-acetyl-5-methoxytryptamine) is an indoleamine with beneficial effects in a broad number of tumors, including the primary liver cancers hepatocarcinoma (HCC) and cholangiocarcinoma (CCA). Among them, melatonin has shown to modulate different cancer-associated processes and enhance drug efficacy against HCC and CCA. Therefore, melatonin has a potential role in improving the current therapeutic landscape in these liver tumors.

Saffron for the Treatment of Human Diseases
Saffron (Crocus sativus L.) is a medicinal plant, originally cultivated in the East and Middle East, and later in some Mediterranean countries. Saffron is obtained from the stigmas of the plant. Currently, the use of saffron is undergoing a revival. The medicinal virtues of saffron, its culinary use and its high added value have led to the clarification of its phytochemical profile and its biological and therapeutic characteristics. Saffron is rich in carotenoids and terpenes. The major products of saffron are crocins and crocetin (carotenoids) deriving from zeaxanthin, pirocrocin and safranal, which give it its taste and aroma, respectively. Saffron and its major compounds have powerful antioxidant and anti-inflammatory properties in vitro and in vivo. Anti-tumor properties have also been described.

Two-Dimensional Nanomaterials
Two-dimensional (2D) nanomaterials have attracted increased interest and exhibited extended applications from nanotechnology to materials science, biomedicine, tissue engineering, as well as energy storage and environmental science. With the development of the synthesis and fabrication of 2D materials, a new family of 2D materials, metal carbides (MCs), revealed promising applications in recent years, and have been utilized for the fabrication of various functional 2D and three-dimensional (3D) nanomaterials for energy and environmental applications, ascribing to the unique physical and chemical properties of MCs. In this review, we present recent advance in the synthesis, fabrication, and applications of 2D and 3D MC-based nanomaterials. This work provides useful information on the preparation, hybridization, structural tailoring, and applications of MC-based materials, and is expected to inspire the design and fabrication of novel and functional MXene materials with improved performance.

Sustainable Value Chain Management
Sustainable value chain management requires finding a balance between the economic, social, and environmental spheres, inside and outside the organizations, in all business functions/processes related to value chain formation. Managers for sustainable management need to have adequate and high-quality financial and non-financial information. They are crucial during times of economic crises (such as those associated with the COVID 19 pandemic). Functional controllers, through their competence and having the appropriate tools to carry out their tasks, can fully meet the information needs of managers in creating a sustainable value chain.

Relevance (Law)
Relevance, in the common law of evidence, is the tendency of a given item of evidence to prove or disprove one of the legal elements of the case, or to have probative value to make one of the elements of the case likelier or not. Probative is a term used in law to signify "tending to prove." Probative evidence "seeks the truth". Generally in law, evidence that is not probative (doesn't tend to prove the proposition for which it is proffered) is inadmissible and the rules of evidence permit it to be excluded from a proceeding or stricken from the record "if objected to by opposing counsel." A balancing test may come into the picture if the value of the evidence needs to be weighed versus its prejudicial nature.

Fractional Poisson Process
In probability theory, a fractional Poisson process is a stochastic process to model the long-memory dynamics of a stream of counts. The time interval between each pair of consecutive counts follows the non-exponential power-law distribution with parameter [math]\displaystyle{ \nu }[/math], which has physical dimension [math]\displaystyle{ [\nu ]=\sec ^{-\mu } }[/math], where [math]\displaystyle{ 0\lt \mu \leq 1 }[/math]. In other words, fractional Poisson process is non-Markov counting stochastic process that exhibits non-exponential distribution of interarrival times. The fractional Poisson process is a continuous-time process that can be thought of as natural generalization of the well-known Poisson process. Fractional Poisson probability distribution is a new member of discrete probability distributions. The fractional Poisson process, Fractional compound Poisson process and fractional Poisson probability distribution function have been invented, developed and encouraged for applications by Nick Laskin (2003) who coined the terms fractional Poisson process, Fractional compound Poisson process and fractional Poisson probability distribution function.
