Christian Contemplation
Christian contemplation, from contemplatio (Latin; Greek θεωρία, theoria), refers to several Christian practices which aim at "looking at", "gazing at", "being aware of" God or the Divine. It includes several practices and theological concepts, and until the sixth century the practice of what is now called mysticism was referred to by the term contemplatio, c.q. theoria. Christianity took up the use of both the Greek (theoria) and Latin (contemplatio, contemplation) terminology to describe various forms of prayer and the process of coming to know God. Eastern and Western traditions of Christianity grew apart as they incorporated the general notion of theoria into their respective teachings. The Catechism of the Catholic Church states that, "the Christian tradition comprises three major expressions of the life of prayer: vocal prayer, meditation, and contemplative prayer. They have in common the recollection of the heart." Three stages are discerned in contemplative practice, namely purgative contemplation, contemplation proper, and the vision of God.

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.

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.

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.

The Sub-Saharan African Food Security Situation
All around the world, inequalities persist in the complex web of social, economic, and ecological factors that mediate food security outcomes at different human and institutional scales. There have been rapid and continuous improvements in agricultural productivity and better food security in many regions of the world due to an expansion in crop area, irrigation, and supportive policy and institutional initiatives. However, in Sub-Saharan Africa, the situation is inverted. Statistics show that food insecurity has risen since 2015 in Sub-Saharan African countries, and the situation has worsened owing to the Ukraine conflict and the ongoing implications of the COVID-19 threat.

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.

Glutamate Decarboxylase
Glutamate decarboxylase (l-glutamate-1-carboxylase, GAD; EC 4.1.1.15) is a pyridoxal-5’-phosphate-dependent enzyme that catalyzes the irreversible α-decarboxylation of l-glutamic acid to γ-aminobutyric acid (GABA) and CO2. The enzyme is widely distributed in eukaryotes as well as prokaryotes, where it—together with its reaction product GABA—fulfils very different physiological functions. The occurrence of gad genes encoding GAD has been shown for many microorganisms, and GABA-producing lactic acid bacteria (LAB) have been a focus of research during recent years. A wide range of traditional foods produced by fermentation based on LAB offer the potential of providing new functional food products enriched with GABA that may offer certain health-benefits. Different GAD enzymes and genes from several strains of LAB have been isolated and characterized recently.

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.

Process of Apoptosis
The term “Apoptosis” originates from Greek, which means the shedding of leaves from trees in autumn or the falling of petals from flowers. Apoptosis was firstly utilized by Kerr, Wyllie, and Currie in 1972 for explaining a morphologically discrete way of cell death. However, multiple concepts of apoptosis were precisely explained several years back. The main concept of apoptosis emerged from the knowledge of the process of programmed cell death that takes place in the developmental cycle of Caenorhabditis elegans.

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).

Microgrid Applications
Microgrids need control and management at different levels to allow the inclusion of renewable energy sources. In this paper, a comprehensive literature review is presented to analyse the latest trends in research and development referring to the applications of predictive control in microgrids. As a result of this review, it was found that the application of predictive control techniques on microgrids is performed for the three control levels and with adaptations of the models in order to include uncertainties to improve their performance and dynamics response. In addition, to ensure system stability, but also, at higher control levels, coordinated operation among the microgrid’s components and synchronised and optimised operation with utility grids and electric power markets. Predictive control appears as a very promising control scheme with several advantages for microgrid applications of different control levels.
