Rumination (Psychology)
Rumination is the focused attention on the symptoms of one's distress, and on its possible causes and consequences, as opposed to its solutions, according to the Response Styles Theory proposed by Nolen-Hoeksema (1998). Because the Response Styles Theory has been empirically supported, this model of rumination is the most widely used conceptualization. Other theories, however, have proposed different definitions for rumination. For example, in the Goal Progress Theory, rumination is conceptualized not as a reaction to a mood state, but as a "response to failure to progress satisfactorily towards a goal". As such, both rumination and worry are associated with anxiety and other negative emotional states; however, its measures have not been unified.

GuideStar
GuideStar USA, Inc. is an information service specializing in reporting on U.S. nonprofit companies. In 2016, its database provided information on 2.5 million organizations. GuideStar was one of the first central sources of information on U.S. nonprofits and is the world's largest source of information about nonprofit organizations. GuideStar was founded in Williamsburg, Virginia in September 1994 and received tax-exempt status in 1996, the same year the company began posting nonprofit organizations' financial reports to the World Wide Web. GuideStar also serves to verify that a recipient organization is established and that donated funds go where the donor intended for individuals looking to give in the wake of disasters. In 2013, GuideStar announced major changes to its GuideStar Exchange program, which allows nonprofits to supplement the public information that is available from the IRS. GuideStar Nonprofit Profiles implemented three seals based on the information a nonprofit provides in its profile: Bronze, Silver, and Gold. In 2016, a new seal that allowed nonprofits to share progress and results for their mission, GuideStar Platinum, was introduced.

Inflammatory Tumor Microenvironment
The development of tumors requires an initiator event, usually exposure to DNA damaging agents that cause genetic alterations such as gene mutations or chromosomal abnormalities, leading to deregulated cell proliferation. Although the mere stochastic accumulation of further mutations may cause tumor progression, it is now clear that an inflammatory microenvironment has a major tumor-promoting influence on initiated cells, in particular when a chronic inflammatory reaction already existed before the initiated tumor cell was formed. Moreover, inflammatory cells become mobilized in response to signals emanating from tumor cells. In both cases, the microenvironment provides signals that initiated tumor cells perceive by membrane receptors and transduce via downstream kinase cascades to modulate multiple cellular processes and respond with changes in cell gene expression, metabolism, and morphology. Cytokines, chemokines, and growth factors are examples of major signals secreted by immune cells, fibroblast, and endothelial cells and mediate an intricate cell-cell crosstalk in an inflammatory microenvironment, which contributes to increased cancer cell survival, phenotypic plasticity and adaptation to surrounding tissue conditions. Eventually, consequent changes in extracellular matrix stiffness and architecture, coupled with additional genetic alterations, further fortify the malignant progression of tumor cells, priming them for invasion and metastasis.

Reputational Risk and Sustainability
Reputation is the contemporary business’s most important commodity. Well, the known will lead to several promising results. Businesses with a solid, good reputation retain consumers and create market satisfaction, hire and sustain high-level staff, build long-term relationships with vendors, attract new buyers, obtain funding at reduced prices and deter future rivals from joining the industry. Since the investor expects that these businesses will achieve long-term profit and future prosperity, they have higher costs and market values.

The Design of Ni-Based Single Crystal Superalloys
The most important performance characteristics of heat-resistant alloys (HRAs) are creep and fatigue resistance, which are very complex functions of chemical composition and microstructure. The microstructure of metal HRAs, among which the first place is occupied by Ni-based alloys, usually consists of two main phases: a solid solution based on the main element containing alloying elements (matrix), and a strengthening phase, which is usually used as intermetallides, carbides and silicides.

Nanofibers in Agriculture and Water Treatment
Natural fibers are an important source for producing polymers, which are highly applicable in their nanoform and could be used in very broad fields such as filtration for water/wastewater treatment, biomedicine, food packaging, harvesting, and storage of energy due to their high specific surface area. These natural nanofibers could be mainly produced through plants, animals, and minerals, as well as produced from agricultural wastes. For strengthening these natural fibers, they may reinforce with some substances such as nanomaterials. Natural or biofiber-reinforced bio-composites and nano–bio-composites are considered better than conventional composites. The sustainable application of nanofibers in agricultural sectors is a promising approach and may involve plant protection and its growth through encapsulating many bio-active molecules or agrochemicals (i.e., pesticides, phytohormones, and fertilizers) for smart delivery at the targeted sites. The food industry and processing also are very important applicable fields of nanofibers, particularly food packaging, which may include using nanofibers for active–intelligent food packaging, and food freshness indicators. The removal of pollutants from soil, water, and air is an urgent field for nanofibers due to their high efficiency. Many new approaches or applicable agro-fields for nanofibers are expected in the future, such as using nanofibers as the indicators for CO and NH3. The role of nanofibers in the global fighting against COVID-19 may represent a crucial solution, particularly in producing face masks.

Hydrochar for Potential Wastewater Treatment Applications
In today’s world, due to population increase, there are many alarming and potential catastrophic problems like climate change, environmental pollution and an enormous mass of wastes constantly produced by humankind to find innovative solutions for the management, recycling, and valorization of biowaste from agricultural production, food processing, and organic household residues. The search for sustainable and efficient wastewater treatment technologies has gained scientific interest; particular focus is on using biowaste to produce hydrochars (HCs) via the hydrothermal carbonization (HTC) process used as adsorbent materials for dye, heavy metal, and emerging pollutant removal. HTC materials derived from renewable resources are an environmentally friendly and adequate way to adsorb pollutants such as organic and inorganic molecules from wastewaters.

Vascular Plant
Vascular plants (from la vasculum 'duct'), also called tracheophytes (/trəˈkiː.əˌfaɪts/) or collectively Tracheophyta (from grc τραχεῖα ἀρτηρία) 'windpipe', and φυτά , form a large group of land plants (c. 300,000 accepted known species) that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). Scientific names for the group include Tracheophyta,:251 Tracheobionta and Equisetopsida sensu lato. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "higher plants," as it was believed that they were further evolved than other plants due to being more complex organisms. However, this is an antiquated remnant of the obsolete scala naturae, and the term is generally considered to be unscientific.

Marasuchus
Marasuchus (meaning "Mara crocodile") is a genus of basal dinosauriform archosaur which is possibly synonymous with Lagosuchus. Both genera lived during the Late Triassic in what is now La Rioja Province, Argentina . Marasuchus contains a single species, Marasuchus lilloensis. Marasuchus lilloensis was originally designated as Lagosuchus lilloensis in 1972. It was considered a new species of Lagosuchus, a contemporary archosaur described the previous year. However, a 1994 study argued that the original material of Lagosuchus was undiagnostic. This would mean that Lagosuchus and its original species (Lagosuchus talampayaensis) could be considered nomen dubia. Specimens of Lagosuchus stored at a museum in San Miguel de Tucuman were considered to be more diagnostic than those of L. talampayensis, and thus they were given a new genus: Marasuchus. A 2019 study redescribed the original material of Lagosuchus and concluded that it was valid and not readily distinguishable from Marasuchus lilloensis. This suggests that Marasuchus lilloensis is a junior synonym of Lagosuchus talampayensis. Specimens referred to the genus Marasuchus possessed some, but not all of the adaptations which traditionally characterized dinosaurs. For example, its proportions indicate that it was likely bipedal as in early dinosaurs. Also, it shared certain specific characteristics with that group, most relating to the hip and the head of the femur. Nevertheless, it lacked certain dinosaur-like features such as a perforated acetabulum, and it had several plesiomorphic ("primitive") features of the ankle.

Affectional Action
Affectional action refers to behavior driven by emotions, sentiments, or personal attachments rather than rational calculations or instrumental goals. It encompasses actions motivated by affection, love, empathy, or other emotional bonds, often leading individuals to prioritize relationships, care, and compassion in their interactions with others, irrespective of utility or self-interest. This concept, elucidated by sociologist Max Weber, highlights the role of emotions in shaping social behavior and relationships within human societies.
