This paper concerns the proper definition of embeddings in purely category-theoretical terms. It is argued that plain category theory cannot capture what, in the general case, constitutes an embedding of one structure in another. We discuss three available solutions to this problem: variants of monics, concrete categories, and allegories. The first and last of these are found to be unable to solve

The potential collapse of Assad’s regime would disturb not only the regional but also trans-regional balance of power at the expense of Iran, leaving it virtually alone amidst foes such as Saudi Arabia and Israel, and rivalrous friends such as Turkey and (potentially) Egypt. The IRI officials have made no secret of their strong desire that Syria under Assad should be protected from what is usually

Objective. Non-neuronal acetylcholine (ACh) has been suggested to be a mediator for the development of various types of cancer. We analyzed a possible role for this molecule in carcinogenesis and/or progression of human colon cancer, in patient biopsies harvested from the colon during surgery. We addressed whether ACh synthesis (by choline acetyltransferase) and/or degradation (by ACh esterase), a

This paper presents findings from a longitudinal, experimental project investigating the effect of translation on the morphosyntactic accuracy of advanced Swedish (L1) learners of English (L2). The subjects were first-year students of English at a Swedish university. The curriculum was communicative and translation (Focus-on-Forms) was used judiciously. The research is couched in cognitive psycho

Constitutional monarchy offers Iran a politically stable and culturally resonant alternative to partisan republicanism. Grounded in both empirical research and philosophical tradition, it combines symbolic authority with institutional continuity, enabling national unity without authoritarianism. Monarchs function as neutral anchors above political conflict, often at lower public cost and with grea

BACKGROUND: The aim of the study was to determine the role of Vascular Endothelial Growth Factor (VEGF) on the microvasculature and on angiogenetic gene expression after partial hepatectomy (PH) in the rat model.METHODS: To determine the effect of exogenous and endogenous VEGF after PH, rats were subjected to 70% PH and treated either with VEGF, anti-VEGF or NaCl. Postoperatively (3-168 h), vessel

The aim of this thesis is to illustrate how collective memory is the basis of ontological security in conflicts and how this hinders reconciliation. The thesis argues that the narrative that stems from the actor must be validated by its relationships otherwise ontological dissonance occurs. Furthermore, the thesis argues that when ontological dissonance occurs the identity does not avoid the disso

Thesis purpose: The purpose is to enhance the understanding of the influence inclusion has on Generation Y consumers when utilised in fashion brands. By isolating two areas of interest namely marginalised gender and size, we aim to provide insight into their effects on the attitude and purchase intention. Methodology: A deductive approach and therefore a quantitative research design is chosen. T

Gwadar port is a deep-sea port that lies at the southwestern coast of the Balochistan province. Since 2002, it has been given quite some attention; the government realized its potential of becoming a major hub port of the region, given its proximity to the Strait of Hormuz, a sea passage through which a fifth of the world’s oil transit occurs. MOUs have been signed and commitments made in excess o

The Common Agricultural Policy (CAP) has a big impact on the national agricultural sector in the EU member states, but the policy can be contentious due to the economic, social and environmental challenges it faces. This essay is testing the hypothesis that these three divisions creates three frameworks under which a divergence in the environmental values can be perceived and comprehended. The cho

Våren 2000 enades Europeiska Rådet om att senast år 2010 ha förvandlat Europa till världens mest konkurrenskraftiga kunskapsbaserade ekonomi. Riktlinjerna samlades i den s.k. Lissabonstrategin. Genom att kritiskt granska dokument som producerats inom ramen för Kommissionens agenda i2010: "Ett informationssamhälle för tillväxt och konkurrens" vill jag synliggöra hur EU beskriver informat

Glypicans are multifunctional cell surface heparan sulphate proteoglycans co-regulating numerous signalling pathways, and are thereby involved in the control of cellular division, differentiation, and morphogenesis. The heparan sulphate (HS) chains are responsible for many of those biological functions; nevertheless recent studies suggest functional roles for the glypican core proteins in mediatin
