Road Markings and Signs in Road Safety
Due to the dynamic nature and complexity of road traffic, road safety is one of the most demanding social challenges. Therefore, contemporary road safety strategies incorporate a multidisciplinary and comprehensive approaches to address this problem and improve the safety of each individual element, i.e., the human, vehicle, and road. Traffic control devices are an important part of road infrastructure, among which road markings and road signs play a significant role. In general, road markings and signs represent basic means of communication between the road authorities and road users and, as such, provide road users with necessary information about the rules, warnings, obligations, and other information related to the upcoming situations and road alignment. The aim of this entry is to briefly present the main functions and characteristics of road markings and signs, and their role in road safety. In addition, practical issues and future trends and directions regarding road markings and signs are discussed.

Peshitta
The Peshitta (Classical Syriac: ܦܫܝܛܬܐ‎ pšîṭtâ) is the standard version of the Bible for churches in the Syriac tradition. The consensus within biblical scholarship, though not universal, is that the Old Testament of the Peshitta was translated into Syriac from Hebrew, probably in the 2nd century AD, and that the New Testament of the Peshitta was translated from the Greek. This New Testament, originally excluding certain disputed books (2 Peter, 2 John, 3 John, Jude, Revelation), had become a standard by the early 5th century. The five excluded books were added in the Harklean Version (616 AD) of Thomas of Harqel. However, the 1905 United Bible Society Peshitta used new editions prepared by the Irish Syriacist John Gwynn for the missing books.

Steroid-Induced Iatrogenic Adrenal Insufficiency
This entry focuses on steroid-induced adrenal insufficiency (SIAI) in children and discusses the latest findings by surveying recent studies. SIAI is a condition involving adrenocorticotropic hormone (ACTH) and cortisol suppression due to high doses or prolonged administration of glucocorticoids. While its chronic symptoms, such as fatigue and loss of appetite, are nonspecific, exposure to physical stressors, such as infection and surgery, increases the risk of adrenal crisis development accompanied by hypoglycemia, hypotension, or shock. The low-dose ACTH stimulation test is generally used for diagnosis, and the early morning serum cortisol level has also been shown to be useful in screening for the condition.

Relative Humidity
Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point.

Polymers in Wastewater Treatment
The utilization of various types of natural and modified polymers for removing toxicant dyes in wastewater generated by the dye industry is reviewed in this article. Dye wastewater contains large amounts of metals, surfactants, and organic matter, which have adverse effects on human health, potentially causing skin diseases and respiratory problems. The removal of dyes from wastewaters through chemical and physical processes has been addressed by many researchers. Currently, the use of natural and modified polymers for the removal of dyes from wastewater is becoming more common. Although modified polymers are preferred for the removal of dyes, due to their biodegradability and non-toxic nature, large amounts of polymers are required, resulting in higher costs.

Stilbene Biosynthesis
Stilbenes are a small family of polyphenolic secondary metabolites that can be found in several distantly related plant species. These compounds act as phytoalexins, playing a crucial role in plant defense against phytopathogens, as well as being involved in the adaptation of plants to abiotic environmental factors. Among stilbenes, trans-resveratrol is certainly the most popular and extensively studied for its health properties. However, many other stilbenes, both monomeric and oligomeric, are currently under intensive investigation due to their biological role and bioactivity.

Testing Effect
The testing effect is the finding that long-term memory is often increased when some of the learning period is devoted to retrieving the to-be-remembered information. The effect is also sometimes referred to as retrieval practice, practice testing, or test-enhanced learning. Retrieval practice may be the best way to refer to the testing effect because the benefits of retrieval-related testing are not limited to tests. It can be more broad, including tools like flash cards and quizzes. The testing effect on memory should be distinguished from more general practice effects, defined in the APA Dictionary of Psychology (2007) as "any change or improvement that results from practice or repetition of task items or activities." The term testing effect is also sometimes used in a more general sense; The Oxford Dictionary of Psychology (2003) defines a testing effect as "any effect of taking tests on the respondents, a typical example being test sophistication." Whereas psychologists who develop tests for personality and intelligence want to avoid practice effects, cognitive psychologists working with educators have begun to understand how to take advantage of tests—not as an assessment tool, but as a teaching/learning tool. It is useful for people to test their knowledge of the to-be-remembered material during the learning process, instead of only reading or otherwise passively studying the material. For example, a student can use flashcards to self-test and receive feedback as they study. The testing effect provides a larger benefit to long-term memory when the tested material is difficult enough to require effort, the rate of retrieval success is high, and feedback with correct answers is given after testing. The testing effect is activated by active recall.

Kraft Lignin
After cellulose, lignin is the second most abundant biopolymer worldwide. Lignins are non-toxic and renewable, and hence may play an essential role during the change-over from a fossil-based to a bio-based economy. Lignin isolation from Kraft cooking is state of the art, the three state of the art processes are summarized and discussed, further the concept of sequerntial liquid lignin recovery is introduced.

The Satanic Bible
The Satanic Bible is a collection of essays, observations, and rituals published by Anton LaVey in 1969. It is the central religious text of LaVeyan Satanism, and is considered the foundation of its philosophy and dogma. It has been described as the most important document to influence contemporary Satanism. Though The Satanic Bible is not considered to be sacred scripture in the way that the Christian Bible is to Christianity, LaVeyan Satanists regard it as an authoritative text as it is a contemporary text that has attained for them scriptural status. It extols the virtues of exploring one's own nature and instincts. Believers have been described as "atheistic Satanists" because they believe that God is not an external entity, but rather something that each person creates as a projection of their own personality—a benevolent and stabilizing force in their life. There have been thirty printings of The Satanic Bible, selling over a million copies. The Satanic Bible is composed of four books: The Book of Satan, The Book of Lucifer, The Book of Belial, and The Book of Leviathan. The Book of Satan challenges the Ten Commandments and the Golden Rule, and promotes Epicureanism. The Book of Lucifer holds most of the philosophy in The Satanic Bible, with twelve chapters discussing topics such as indulgence, love, hate, and sex. LaVey also uses the book to dispel rumors surrounding the religion. In The Book of Belial, LaVey details rituals and magic. He discusses the required mindset and focus for performing a ritual, and provides instructions for three rituals: those for sex, compassion, or destruction. The Book of Leviathan provides four invocations for Satan, lust, compassion, and destruction. It also lists the nineteen Enochian Keys (adapted from John Dee's Enochian keys), provided both in Enochian and in English translation. There have been both positive and negative reactions to The Satanic Bible. It has been described as "razor-sharp" and "influential". Criticism of The Satanic Bible stems both from qualms over LaVey's writing and disapproval of the content itself. LaVey has been criticized for plagiarizing sections, and accusations have been made that his philosophies are largely borrowed. Attempts have been made to ban the book in schools, public libraries, and prisons, though these attempts are somewhat rare.

Synesthesia
Synesthesia (American English) or synaesthesia (British English) is a perceptual phenomenon in which stimulation of one sensory or cognitive pathway leads to involuntary experiences in a second sensory or cognitive pathway. People who report a lifelong history of such experiences are known as synesthetes. Awareness of synesthetic perceptions varies from person to person. In one common form of synesthesia, known as grapheme–color synesthesia or color–graphemic synesthesia, letters or numbers are perceived as inherently colored. In spatial-sequence, or number form synesthesia, numbers, months of the year, or days of the week elicit precise locations in space (e.g., 1980 may be "farther away" than 1990), or may appear as a three-dimensional map (clockwise or counterclockwise). Synesthetic associations can occur in any combination and any number of senses or cognitive pathways. Little is known about how synesthesia develops. It has been suggested that synesthesia develops during childhood when children are intensively engaged with abstract concepts for the first time. This hypothesis – referred to as semantic vacuum hypothesis – could explain why the most common forms of synesthesia are grapheme–color, spatial sequence, and number form. These are usually the first abstract concepts that educational systems require children to learn. Difficulties have been recognized in adequately defining synesthesia. Many different phenomena have been included in the term synesthesia, and in many cases the terminology seems to be inaccurate. A more accurate but less common term may be ideasthesia. The earliest recorded case of synesthesia is attributed to the Oxford University academic and philosopher John Locke, who, in 1690, made a report about a blind man who said he experienced the color scarlet when he heard the sound of a trumpet. However, there is disagreement as to whether Locke described an actual instance of synesthesia or was using a metaphor. The first medical account came from German physician Georg Tobias Ludwig Sachs in 1812. The term is from the Ancient Greek σύν syn, 'together', and αἴσθησις aisthēsis, 'sensation'.
