Comparison of Different Types of Palatal Expanders
Maxillary bone contraction is caused by genetics or ambiental factors and is often accompanied by dental crowding, with the possibility of canine inclusion, crossbite, class II and III malocclusion, temporomandibular joint disorder, and obstructive sleep apnea (OSAS). Transverse maxillary deficits, in which the maxillary growth is unusually modest, are frequently treated with maxillary expansion. The purpose herein is to compare the dental and skeletal effects of different types of expanders, particularly the Leaf Expander, rapid and slow dental-anchored or skeletal-anchored maxillary expanders.

Structural Changes in Albumen Quality during Storage Period
The egg storage environment influences the nutritional and functional properties of albumen. Changes in albumen quality during storage are characterized by various physical and chemical reactions that are affected by either an increase or a decrease in storage time and temperature. Changes in albumen structure indicate a decline in albumen quality during storage. Albumen traits, such as Haugh unit value (HU) value, albumen pH, and thick albumen height, are often used as indicators of albumen quality during storage and are influenced by storage conditions in a time- and temperature-dependent manner. These traits would invariably influence the albumen’s functional, rheological, and biological properties.

Ordnance QF 75 Mm
The Ordnance QF 75 mm, abbreviated to OQF 75 mm, was a British tank-gun of the Second World War. It was obtained by boring out the Ordnance QF 6 pounder ("6 pdr") 57-mm anti-tank gun to 75-mm, to give better performance against infantry targets in a similar fashion to the 75mm M3 gun fitted to the American Sherman tank. The QF came from "quick-firing", referring to the use of ammunition with the shell and propellant in a single cartridge. The gun was also sometimes known as ROQF from Royal Ordnance (the manufacturer) Quick-Firing.

Sesame
Sesame (Sesamum indicum L.) is an important oilseed crop with well-developed value chains. It is Ethiopia’s most valuable export commodity after coffee (Coffea arabica L.), contributing to socioeconomic development. The productivity of the crop is low and stagnant in Ethiopia and other major sesame growing regions in sub-Saharan Africa (<0.6 t/ha) due to a multitude of production constraints. The low yield of sesame is attributable to a lack of high-yielding and well-adapted varieties, susceptibility to capsule shattering, the prevalence of biotic and abiotic stresses, and a lack of modern production technologies such as optimal agronomic managing practices, row planters, harvesters, and storage facilities.

Association between Membrane Proteins and Disease
Cell membranes, including membrane carrier proteins, membrane channel proteins and ATP drive pumps, are the main transporters. Membrane transporters have wide, but specific tissue distributions. They can impact on multiple endogenous and xenobiotic processes. Transport proteins constitute approximately 10% of most proteomes and play vital roles in the translocation of solutes across the membranes of all organisms. The receptor proteins on the cell membrane are also important structures involved in substrate transport and signal communication. The obstacles of cell transport-related proteins directly lead to the lack or excess of certain substances in cells.

Discover Card
Discover is a credit card brand issued primarily in the United States. It was introduced by Sears in 1985. When launched, Discover did not charge an annual fee and offered a higher-than-normal credit limit, features that were disruptive to the existing credit card industry. A subsequent innovation was "Cashback Bonus" on purchases. Most cards with the Discover brand are issued by Discover Bank, formerly the Greenwood Trust Company. Discover transactions are processed through the Discover Network payment network. In 2005, Discover Financial Services acquired Pulse, an electronic funds transfer network, allowing it to market and issue debit and ATM cards. In February 2006, Discover Financial Services announced that it would begin offering Discover Debit cards to other financial institutions, made possible by the acquisition of Pulse. Discover is the fourth largest credit card brand in the U.S., behind Visa, MasterCard and American Express, with nearly 44 million cardholders.

Rada (Fiqh)
Raḍāʿ or riḍāʿa (Arabic: رضاع, رضاعة  pronounced [rɪˈdˤɑːʕ(æ)], "breastfeeding") is a technical term in Sunni Islamic jurisprudence (fiqh) meaning "the suckling which produces the legal impediment to marriage of foster-kinship", and refers to the fact that under Sunni jurispurdence, a wet nurse is considered related to the infant she nurses. The term derives from the infinitive noun of the Arabic word radiʿa or radaʿa ("he sucked the breast of his mother"). Often it is translated as "fosterage" or "milk kinship". The concept of radāʿ derives from Islamic and pre-Islamic notions concerning the state of blood relations whereby a wet nurse (and her close relations) and the baby she is nursing (and his or her close family) are deemed related to one another (a status known as mahram) through the act of breastfeeding. One important consequence is that the wet nurse and her family are forbidden to marry the baby and members of the baby's family (e.g. the nursling's biological brother with the milk-mother's biological daughter). Conversely, the milk-relationship allows usually forbidden familiarities between the two groups, (e.g. if the nursling is male, when he becomes an adult he may view the milk-mother and her close female relatives unveiled or in private, exactly as if he were a relation). Thus, according to some Sahih hadith, nursing an adult male could be used as a workaround to Islamic gender segregation, so that a male may be allowed in proximity to the nursing woman, her sisters and her daughters.

Electrical Conductivity of Nanoparticle-Enhanced Fluids
Research on nanoparticle-enhanced fluids’ electrical conductivity is at its beginning at this moment and the augmentation mechanisms are not fully understood. Basically, the mechanisms for increasing the electrical conductivity are described as electric double layer influence and increased particles’ conductance. Another idea that has resulted from state of the art is that the stability of nanofluids can be described with the help of electrical conductivity tests, but more coordinated research is needed. Concluding, this analysis has shown that a lot of research work is needed in the field of nanofluids’ electrical characterization and specific applications.

Mathematical Physics
Mathematical physics refers to the development of mathematical methods for application to problems in physics. The Journal of Mathematical Physics defines the field as "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories". An alternative definition would also include those mathematics that are inspired by physics (also known as physical mathematics).

Alienation
Alienation, in a sociological and philosophical context, refers to a condition in which individuals feel estranged, disconnected, or separated from themselves, others, and the broader society. The concept has its roots in the works of Karl Marx, who developed the idea as a central component of his critique of capitalism. However, the concept of alienation has been explored and expanded upon by various thinkers across different disciplines.

Beta-Catenin
Catenin beta-1, also known as β-catenin, is a protein that in humans is encoded by the CTNNB1 gene. β-catenin is a dual function protein, involved in regulation and coordination of cell–cell adhesion and gene transcription. In humans, the CTNNB1 protein is encoded by the CTNNB1 gene. In Drosophila, the homologous protein is called armadillo. β-catenin is a subunit of the cadherin protein complex and acts as an intracellular signal transducer in the Wnt signaling pathway. It is a member of the catenin protein family and homologous to γ-catenin, also known as plakoglobin. Beta-catenin is widely expressed in many tissues. In cardiac muscle, beta-catenin localizes to adherens junctions in intercalated disc structures, which are critical for electrical and mechanical coupling between adjacent cardiomyocytes. Mutations and overexpression of β-catenin are associated with many cancers, including hepatocellular carcinoma, colorectal carcinoma, lung cancer, malignant breast tumors, ovarian and endometrial cancer. Alterations in the localization and expression levels of beta-catenin have been associated with various forms of heart disease, including dilated cardiomyopathy. β-catenin is regulated and destroyed by the beta-catenin destruction complex, and in particular by the adenomatous polyposis coli (APC) protein, encoded by the tumour-suppressing APC gene. Therefore, genetic mutation of the APC gene is also strongly linked to cancers, and in particular colorectal cancer resulting from familial adenomatous polyposis (FAP).

Kamakhya
Kamakhya is an important Hindu Tantric goddess of desire who evolved in the Himalayan hills. She is worshiped as Siddha Kubjika, and is also identified as Kali and Maha Tripura Sundari. According to the Tantric texts (Kalika Purana, Yogini Tantra) that are the basis for her worship at the Kamakhya temple, a 16th-century temple in the Kamrup district of Assam. The earlier manifest of the goddess sanctified at the Garo hills is destroyed, although the Vatsayana priests are said to have carried away the manifest of the goddess to the Hindu kingdom in Kashmir and later sanctified in a remote hill forest in Himachal Pradesh. Her name means "renowned goddess of desire," and she resides at the presently rebuilt Kamakhya Temple in 1645 C. The temple is primary amongst the 51 Shakti Peethas related to the sect that follows Sati, and remains one of the most important Shakta temples and Hindu pilgrimage sites in the world.

Energy Condition
In relativistic classical field theories of gravitation, particularly general relativity, an energy condition is a generalization of the statement "the energy density of a region of space cannot be negative" in a relativistically-phrased mathematical formulation. There are multiple possible alternative ways to express such a condition such that can be applied to the matter content of the theory. The hope is then that any reasonable matter theory will satisfy this condition or at least will preserve the condition if it is satisfied by the starting conditions. Energy conditions are not physical constraints per se, but are rather mathematically imposed boundary conditions that attempt to capture a belief that "energy should be positive". Many energy conditions are known to not correspond to physical reality—for example, the observable effects of dark energy are well-known to violate the strong energy condition. In general relativity, energy conditions are often used (and required) in proofs of various important theorems about black holes, such as the no hair theorem or the laws of black hole thermodynamics.
