Etiopathogenesis of Psoriasis
The underlying basis of psoriasis is skin inflammation (and, in the case of psoriatic arthritis, inflammation of the connective tissue which makes up the joints and the joint ligaments). The characteristic features of skin inflammation include hyperplasia of the epidermis, parakeratosis, and an inflammatory infiltration consisting of dendritic cells, macrophages, T-lymphocytes, and neutrophils. Abnormalities in the skin’s immune response are responsible for the development of the inflammation.

Armenian Highlands
The Armenian Highlands (Armenian: Հայկական լեռնաշխարհ, romanized: Haykakan leṙnašxarh; also known as the Armenian Upland, Armenian plateau, or Armenian tableland) is the most central and the highest of the three plateaus that together form the northern sector of Western Asia. Clockwise starting from the west, the Armenian Highlands are bounded by the Anatolian plateau, the Caucasus, the Kura-Aras lowlands, the Iranian Plateau, and Mesopotamia. The highlands are divided into western and eastern regions, defined by the Ararat Valley where Mount Ararat is located. Western Armenia is nowadays referred to as eastern Anatolia, and Eastern Armenia as the Lesser Caucasus or Caucasus Minor, and historically as the Anti-Caucasus, meaning "opposite the Caucasus". During the Iron Age, the region was known by variations of the name Ararat (Urartu, Uruatri, Urashtu). Later, the Highlands were known as Armenia Major, a central region to the history of Armenians, and one of the four geopolitical regions associated with Armenians, the other three being Armenia Minor, Sophene, and Commagene. The population of the region has been primarily Armenian for most of its known history. Prior to the appearance of nominally Armenian people in historical records, historians have hypothesized that the region must have been home to various ethnic groups who became homogenous when the Armenian language came to prominence. The population of the Armenian Highlands seem to have had a high level of regional genetic continuity for over 6,000 years. Recent studies have shown that the Armenian people are indigenous to the Armenian Highlands and form a distinct genetic isolate in the region. The region was also inhabited during Antiquity by minorities such as Assyrians, Georgians, Greeks, Jews, and Iranians. During the Middle Ages, Arabs and particularly Turkmens and Kurds settled in large numbers in the Armenian Highlands. The Christian population of the western half of the region was exterminated during the Armenian genocide of 1915. Today, the eastern half is mainly inhabited by Armenians, Azerbaijanis and Georgians, while the western half is mainly inhabited by Kurds (including Yazidis), Turks, Azerbaijanis, Armenians (included crypto-Armenians and Hemshins) and Zazas. The region was administered for most of its known history by Armenian nobility and states, whether it was as part of a fully independent Armenian state, as vassals, or as part of a foreign state. Since the 1040s, the highlands have been under the rule of various Turkic peoples and the Safavid dynasty, with pockets of Armenian autonomy in places such as Artsakh. Much of Eastern Armenia, which had been ruled by the Safavids from the 16th century, became part of the Russian Empire in 1828 and was later incorporated into the Soviet Union, while much of Western Armenia was under the rule of the Ottoman Empire and later incorporated into Turkey. Today, the region is divided between Turkey, Georgia, Armenia, Azerbaijan and Iran.

Arba'een
Template:HusaynTemplate:Islamic Culture Arba'ein (Arabic: الأربعين), Chehellom (Persian: چهلم‎, "the fortieth day") is a Shia religious observance that occurs forty days after the Day of Ashura. It commemorates the martyrdom of Al-Husayn ibn Ali, the grandson of Muhammad, who was martyred on the 10th day of the month of Muharram.Imam Hussain ibn Ali and 71 of his companions were martyred by Ubayd Allah ibn Ziyad's army under the governance of Yazeed Malhoon in the Battle of Karbala in 61 AH (680 CE). Arba'ein or forty days is also the usual length of mourning after the death of a family member or loved one in many Muslim traditions. Arba'ein is the largest annual pilgrimage in the world, in which up to 40 million (In reality, there are no reliable methods for tallying the number of site visitors. This is an entirely estimated set of statistics. Logically, it is possible to gather 40m persons on a small city) people go to the city of Karbala in Iraq.

Chemical Composition on Heating Value of Biomass
Biomass has become an increasingly important resource for energy generation. It is well known that the heating value of lignin is significantly higher (23.26–25.58 MJ/kg) than that of polysaccharides (18.6 MJ/kg), while extractives often have higher heating values (HHVs) over 30 MJ/kg, depending on their oxidation levels. Therefore, the proportions of the chemical components in biomass determine its HHV.

Prospective Memory
Prospective memory is a form of memory that involves remembering to perform a planned action or recall a planned intention at some future point in time. Prospective memory tasks are common in daily life and range from the relatively simple to extreme life-or-death situations. Examples of simple tasks include remembering to put the toothpaste cap back on, remembering to reply to an email, or remembering to return a rented movie. Examples of highly important situations include a patient remembering to take medication or a pilot remembering to perform specific safety procedures during a flight. In contrast to prospective memory, retrospective memory involves remembering people, events, or words that have been encountered in the past. Whereas retrospective memory requires only the recall of past events, prospective memory requires the exercise of retrospective memory at a time that has not yet occurred. Prospective memory is thus considered a form of "memory of the future". Retrospective memory involves the memory of what we know, containing informational content; prospective memory focuses on when to act, rather than focusing on informational content. There is some evidence demonstrating the role of retrospective memory in the successful execution of prospective memory, but this role seems to be relatively small.

Courage
Courage (also called bravery or valor) is the choice and willingness to confront agony, pain, danger, uncertainty, or intimidation. Valor is courage or bravery, especially in battle. Physical courage is bravery in the face of physical pain, hardship, even death, or threat of death; while moral courage is the ability to act rightly in the face of popular opposition, shame, scandal, discouragement, or personal loss. The classical virtue of fortitude (andreia, fortitudo) is also translated "courage", but includes the aspects of perseverance and patience. In the Western tradition, notable thoughts on courage have come from philosophers Socrates, Plato, Aristotle, Aquinas, and Kierkegaard, as well as Christian beliefs and texts. In the Hindu tradition, mythology has given many examples of bravery, valor and courage, with examples of both physical and moral courage exemplified. In the Eastern tradition, some thoughts on courage were offered by the Tao Te Ching.

Introduction of Campus Microgrids
Campus Microgrids are a scattered group of power sources and electrical loads that are usually synchronous with the primary grid, called the utility grid. The multiple uncertainties in a microgrid, such as limited photovoltaic generations, ups and downs in the market price, and controlling different loads, are challenging points in managing campus energy with multiple microgrid systems and are a hot topic of research in the current era. Microgrids deployed at multiple campuses can be successfully operated with an exemplary energy management system (EMS) to address these challenges, offering several solutions to minimize the greenhouse gas (GHG) emissions, maintenance costs, and peak load demands of the microgrid infrastructure.

Golgi apparatus and Huntington’s Disease
Huntington’s disease (HD) is caused by expansion of polyglutamine repeats in the protein huntingtin, which affects the corpus striatum of the brain. The polyglutamine repeats in mutant huntingtin cause its aggregation and elicit toxicity by affecting several cellular processes, which include dysregulated organellar stress responses. The Golgi apparatus not only plays key roles in the transport, processing, and targeting of proteins, but also functions as a sensor of stress, signaling through the Golgi stress response. Unlike the endoplasmic reticulum (ER) stress response, the Golgi stress response is relatively unexplored. We have identified a Golgi stress response pathway which is dysregulated in HD.

Major Basilica
A major basilica (Latin: Basilica maior; plural: Basilicae maiores) is one of the four highest-ranking Roman Catholic church buildings, all of which are also papal basilicas: the Archbasilica of Saint John Lateran, St. Peter's Basilica, the Basilica of Saint Paul Outside the Walls, and the Basilica di Santa Maria Maggiore. All of them are located within the diocese of Rome: St. Peter's Basilica is located in Vatican City and thus within the territory and sovereign jurisdiction of the Holy See. The other three are geographically located in Italian territory, but enjoy extraterritorial status under the Lateran Treaty. The Archbasilica of Saint John in the Lateran is the seat of the Pope and the site of the Papal Cathedra, and is the oldest and first in rank of the major basilicas. All other churches that have the title of basilica are minor basilicas (Latin: basilica minor).

Paleo-Hebrew Leviticus Scroll
Paleo-Hebrew Leviticus scroll, known also as 11QpaleoLev, is an ancient text preserved in one of the Qumran group of caves, and which provides a rare glimpse of the script used formerly by the nation of Israel in writing Torah scrolls during its pre-exilic history. The fragmentary remains of the Torah scroll is written in the Paleo-Hebrew script and was found stashed-away in a cave at Qumran, showing a portion of Leviticus. The scroll is thought to have been penned by the scribe between the late 2nd-century BCE to early 1st-century BCE, while others place its writing in the 1st-century CE. The Paleo-Hebrew Leviticus scroll, although many centuries more recent than the well-known earlier ancient paleo-Hebrew epigraphic materials, such as the Royal Steward inscription from Siloam, Jerusalem (eighth century BCE), now in the Museum of the Ancient Orient, Istanbul, and the Phoenician inscription on the sarcophagus of King Eshmun-Azar at Sidon, dating to the fifth-fourth century BCE, the Lachish ostraca (ca. 6th-century BCE), the Gezer calendar (ca. 950–918 BCE), and the paleo-Hebrew sacerdotal blessing discovered in 1979 near the St Andrew's Church in Jerusalem, is of no less importance to palaeography - even though the manuscript is fragmentary and only partially preserved on leather parchment. Today, the paleo-Hebrew Leviticus scroll (11QpaleoLev) is housed at the Israel Antiquities Authority (IAA), but is not on public display.
