Venice Charter
The Venice Charter for the Conservation and Restoration of Monuments and Sites is a set of guidelines, drawn up in 1964 by a group of conservation professionals in Venice, that provides an international framework for the conservation and restoration of historic buildings. However, the document is now seen as outdated, representing Modernist views opposed to reconstruction. Reconstruction is now cautiously accepted by UNESCO in exceptional circumstances if it seeks to reflect a pattern of use or cultural practice that sustains cultural value, and is based on complete documentation without reliance on conjecture. The change in attitude can be marked by the reconstruction in 2015 of the Sufi mausoleums at the Timbuktu World Heritage Site in Mali after their destruction in 2012.

Triangle Center
In geometry, a triangle center (or triangle centre) is a point in the plane that is in some sense a center of a triangle akin to the centers of squares and circles, that is, a point that is in the middle of the figure by some measure. For example the centroid, circumcenter, incenter and orthocenter were familiar to the ancient Greeks, and can be obtained by simple constructions. Each of these classical centers has the property that it is invariant (more precisely equivariant) under similarity transformations. In other words, for any triangle and any similarity transformation (such as a rotation, reflection, dilation, or translation), the center of the transformed triangle is the same point as the transformed center of the original triangle. This invariance is the defining property of a triangle center. It rules out other well-known points such as the Brocard points which are not invariant under reflection and so fail to qualify as triangle centers. All centers of an equilateral triangle coincide at its centroid, but they generally differ from each other on scalene triangles. The definitions and properties of thousands of triangle centers have been collected in the Encyclopedia of Triangle Centers.

Biostimulants Application in Horticultural Crops under Abiotic Stress Conditions
Abiotic stresses strongly affect plant growth, development, and quality of production; final crop yield can be really compromised if stress occurs in plants’ most sensitive phenological phases. Additionally, the increase of crop stress tolerance through genetic improvements requires long breeding programmes and different cultivation environments for crop performance validation. Biostimulants have been proposed as agronomic tools to counteract abiotic stress. Indeed, these products containing bioactive molecules have a beneficial effect on plants and improve their capability to face adverse environmental conditions, acting on primary or secondary metabolism. Many companies are investing in new biostimulant products development and in the identification of the most effective bioactive molecules contained in different kinds of extracts, able to elicit specific plant responses against abiotic stresses. Most of these compounds are unknown and their characterization in term of composition is almost impossible; therefore, they could be classified on the basis of their role in plants. Biostimulants have been generally applied to high-value crops like fruits and vegetables; thus, in this review, we examine and summarise literature on their use on vegetable crops, focusing on their application to counteract the most common environmental stresses.

Polymeric Surfactants
Polymeric surfactants are surfactant molecules that have a polymeric backbone, which can be made up of various repeating units. These surfactants have both hydrophilic and hydrophobic segments, which allows them to interact with both water and oil. Polymeric surfactants are used in a variety of industrial applications, such as in the production of paints, adhesives, and coatings. They can improve the stability and performance of these products by reducing the surface tension and promoting the dispersion of pigments and fillers. In addition, polymeric surfactants are also used in the formulation of personal care products, such as shampoos, conditioners, and body washes. They can help to improve the texture and feel of these products, as well as enhance their cleaning and conditioning properties. One of the key advantages of polymeric surfactants is their ability to form stable micelles in solution. These micelles are aggregates of surfactant molecules that form a spherical structure with the hydrophobic segments on the inside and the hydrophilic segments on the outside. This allows for efficient emulsification of oil and water, which is important in a variety of industrial processes. Polymeric surfactants are a versatile class of surfactants that offer several unique properties and advantages in various applications. They are commonly used as emulsifiers, stabilizers, and thickening agents, and have potential applications in areas such as agriculture, oil and gas, and papermaking. Polymeric surfactants are a diverse class of surfactants that can be classified based on their composition, molecular weight, and degree of polymerization. They offer a range of unique properties and advantages in various applications, including cosmetics, food and beverage products, pharmaceuticals, and agriculture.

Thiosugars of Biological Significance
Thiosugars are important compounds because of their structural complexity and crucial biological activities. Therefore, a series of methods are developed for their synthesis using new methods. Unlike, oxygen sugars, thiosugars are more stable and therefore, much scope exists to alter their structures by chemical manipulations. Notably, thiosugars can act as glycosyl donors as well as acceptors.  Many functionalized thiosugars occur naturally and are potential targets for therapeutics. Synthesis of thiosugars following convergent route is a challenge.  Over the years, scientists have explored thiosugars through numerous green and sustainable methods. These studies are highly significant and timely since it opens the door towards carbohydrate-based drugs.

Developing the Socio-Emotional Intelligence of Doctoral Students
Socio-emotional intelligence is the capacity to consider emotions, intuition, and cognition to identify, manage and express emotions and to respond to social situations with authenticity, openness and fairness. By doing so, individuals will achieve a sense of wellbeing and build meaningful relations whilst having a positive impact on the environment, others and themselves. The term doctoral student refers to a postgraduate researcher completing a doctoral degree. Supervisor is the term used in academia for an academic guiding and supporting the doctoral student. Doctoral supervisions usually include at least two academics as supervisors. A doctoral degree in the UK normally focuses on the in-depth study of a topic; these can be chosen by the doctoral student or sometimes be content-specific if a scholarship is attached.

Occultism in Nazism
Nazism and occultism describes a range of theories, speculation and research into the origins of Nazism and its possible relation to various occult traditions. Such ideas have been a part of popular culture since at least the early 1940s, during World War II, and gained renewed popularity starting in the 1960s. There are documentaries and books on the topic, among the most significant are The Morning of the Magicians (1960) and The Spear of Destiny (1972). Nazism and occultism has also been featured in numerous films, novels, comic books and other fictional media. Some good examples are the film Raiders of the Lost Ark (1981) and the comic book series Hellboy. Historian Nicholas Goodrick-Clarke analyzed the topic in The Occult Roots of Nazism in which he argued there were in fact links between some ideals of Ariosophy and Nazi ideology. He also analyzed the problems of the numerous popular occult historiography books written on the topic. He sought to separate empiricism and sociology from the modern mythology of Nazi occultism that exists in many books which "have represented the Nazi phenomenon as the product of arcane and demonic influence". He considered most of these to be "sensational and under-researched".

Mono
Mono is a free and open-source project to create an Ecma standard-compliant .NET Framework-compatible software framework, including a C# compiler and a Common Language Runtime. Originally by Ximian, it was later acquired by Novell, and is now being led by Xamarin, a subsidiary of Microsoft and the .NET Foundation. The stated purpose of Mono is not only to be able to run Microsoft .NET applications cross-platform, but also to bring better development tools to Linux developers. Mono can be run on many software systems including Android, most Linux distributions, BSD, macOS, Windows, Solaris, and even some game consoles such as PlayStation 3, Wii, and Xbox 360. The Mono project has been controversial within the open-source community, as it implements portions of .NET Framework that may be covered by Microsoft patents. Although standardized portions of .NET Framework are covered under Microsoft Open Specification Promise—a covenant stating that Microsoft will not assert its patents against implementations of its specifications under certain conditions—other portions are not, which led to concerns that the Mono project could become the target of patent infringement lawsuits. Following Microsoft's open-sourcing of several core .NET technologies since 2014 and its acquisition of Xamarin in the beginning of 2016, an updated patent promise has been issued for the Mono project (§ Mono and Microsoft's patents). The logo of Mono is a stylized monkey's face, mono being Spanish for monkey.

Short-Term Memory
Short-term memory (or "primary" or "active memory") is the capacity for holding, but not manipulating, a small amount of information in mind in an active, readily available state for a short period of time. For example, short-term memory can be used to remember a phone number that has just been recited. The duration of short-term memory (when rehearsal or active maintenance is prevented) is believed to be in the order of seconds. A commonly cited capacity of items to remember is The Magical Number Seven, Plus or Minus Two (also called Miller's Law, despite Miller calling the figure "little more than a joke" (Miller, 1989, page 401)). Cowan (2001) suggests that a more realistic figure is 4±1 items. In contrast, long-term memory holds information indefinitely. Short-term memory should be distinguished from working memory, which refers to structures and processes used for temporarily storing and manipulating information (see details below).

Neuroprotective Effects of Quercetin
Quercetin is a flavonoid compound present in a wide variety of vegetables and fruit, such as onion, asparagus, red leaf lettuce, cilantro, lovage, dill, capers, apples, and berries. Quercetin represents the highest percentage of total flavonoid intake and is the most important component of flavonol subclass, often the base of other flavonoids. Thus, quercetin has been demonstrated to exert neuroprotective effects in several neurodegenerative disorders as well as antioxidant, anti-inflammatory, anti-cancer, anti-obesity, anti-viral and anti-microbial properties, and cardioprotective and hepatoprotective activities.

Safety of Food Fungal Pigments
Pigments play a major role in many industries. Natural colors are usually much safer when compared to synthetic colors and may even possess some medicinal benefits. Synthetic colors are economical and can easily be produced compared to natural colors. In addition, raw plant materials for natural colors are limited and season dependent. Microorganisms provide an alternative source for natural colors and, among them, fungi provide a wide range of natural colorants that could easily be produced cheaply and with high yield. Along with pigment, some microbial strains are also capable of producing a number of mycotoxins. The commercial use of microbial pigments relies on the safety of colorants.

Iranian Household Electricity Use Compared to Selected Countries
Buildings account for nearly 40% of energy use in global contexts and climatic conditions tend to contribute to consumption. Human activities are also influential in energy consumption and carbon dioxide (CO2) emissions that lead to global warming. Residential buildings are responsible for a considerable share. There are countries aggravating this situation by heavily relying on fossil fuels. Oil-rich countries are allocating an energy subsidy to the public, making energy cheaper for their consumers. This may result in negative consequences, including households’ inefficient energy use behaviours in countries such as Iran. Beyond the impact of energy subsidy allocation, this study aims to explore the climatic and non-climatic factors that affect the increase in domestic electricity use, particularly in Iran. For this purpose, this study begins with a comparative analysis between countries with and without the energy subsidy to examine the trends in domestic electricity use. Afterwards, the tendency of households’ electricity use in Iran will be analysed in consideration of climatic and non-climatic factors among several provinces in Iran. This study exploited published statistical data for the analysis. The results indicate the tendency of increased domestic electricity use due to the country’s generous subsidy offered to the public as well as climatic and non-climatic factors in Iran. These results may provide an opportunity for future studies regarding building occupants’ inefficient energy use behaviours for policy enactment in Iran and other oil-rich countries.

Artificial Intelligence in Biological Sciences
Artificial intelligence (AI), currently a cutting-edge concept, has the potential to improve the quality of life of human beings. The fields of AI and biological research are becoming more intertwined, and methods for extracting and applying the information stored in live organisms are constantly being refined. As the field of AI matures with more trained algorithms, the potential of its application in epidemiology, the study of host–pathogen interactions and drug designing widens. AI is now being applied in several fields of drug discovery, customized medicine, gene editing, radiography, image processing and medication management. More precise diagnosis and cost-effective treatment will be possible in the near future due to the application of AI-based technologies. In the field of agriculture, farmers have reduced waste, increased output and decreased the amount of time it takes to bring their goods to market due to the application of advanced AI-based approaches. Moreover, with the use of AI through machine learning (ML) and deep-learning-based smart programs, one can modify the metabolic pathways of living systems to obtain the best possible outputs with the minimal inputs. Such efforts can improve the industrial strains of microbial species to maximize the yield in the bio-based industrial setup.
