We investigate the mechanism responsible for the formation of mesoporous silica formed with the so-called costructure directing agent (CSDA) route. The synthesis relies on the interaction between silica source (tetraethylorthosilicate), cationic surfactant (C18H37N+(CH3)2(CH2)3N+(CH3)3Br2), and CSDA (carboxyethylsilanetriol), which results in a material functionalized with carboxylic groups. Depen

In this paper, we present a detailed comparison of the bottom production in gluon-gluon, photon-gluon, photon-photon, Pomeron-gluon, Pomeron-Pomeron and Pomeron-photon interactions at the LHC. The transverse momentum, pseudorapidity and ξ dependencies of the cross sections are calculated at LHC energy using the Forward Physics Monte Carlo, which allows us to obtain realistic predictions for the bo

Trust is a valuable relational asset for companies. A high level of public trust can bring a number of benefits to business organizations, including increased customer satisfaction, higher investor confidence, and fewer regulatory restrictions (Barney and Hansen, 1994; García-Marzá, 2005; Ingenhoff and Sommer, 2010; Pirson and Malhotra, 2011). But trust is also a fragile commodity; it takes a lo

We propose a signal-to-noise criterion which predicts whether a feature of a given size and scattering strength, placed inside a larger object, can be retrieved with two common X-ray imaging techniques: coherent diffraction imaging and projection microscopy. This criterion, based on how efficiently these techniques detect the scattered photons and validated through simulations, shows in general th

Directed differentiation of human induced pluripotent stem cells (iPSCs) into retinal pigmented epithelium (RPE) holds great promise in cell replacement therapy for patients suffering from degenerative eye diseases, including age-related macular degeneration (AMD). In this study, we generated iPSCs from human dermal fibroblasts (HDFs) by electroporation with episomal plasmid vectors encoding OCT4,

The topological crystalline insulator tin telluride is known to host superconductivity when doped with indium (Sn1-xInxTe), and for low indium content (x=0.04) it is known that the topological surface states are preserved. Here we present the growth, characterization, and angle resolved photoemission spectroscopy analysis of samples with much heavier In doping (up to x≈0.4), a regime where the sup

An extensive phenomenological study of the Drell-Yan (DY) process in pp collisions at various energies is performed in the color dipole framework. Besides previously studied γ∗ production we also include the Z0 contribution relevant at large dilepton invariant masses. We investigate the DY cross section differential in invariant mass, rapidity and transverse momentum of the dilepton pair in pp col

Physical therapy and social interactions between the stroke patient and health care professionals or relatives facilitate the process of recovery and promote the improvement of neurological function after stroke. These observations can be mimicked in the experimental setting with the concept of enriched environment. The enriched environment is a housing condition for rodents combining social inter

Temperature disturbances are common in patients with severe traumatic brain injury. The possibility of an adaptive, potentially beneficial role for fever in patients with severe brain trauma has been dismissed, but without good justification. Fever might, in some patients, confer benefit. A cadre of clinicians and scientists met to debate the clinically relevant, but often controversial issue abou

The levels of protein kinase C-γ (PKC-γ) and the calcium/calmodulin-dependent kinase II-α (CaMKII-α) were measured in crude synaptosomal (P2), particulate (P3), and cytosolic (S3) fractions of the neocortex of rats exposed to 1-hour and 2-hour middle cerebral artery occlusion (MCAO) and 2-hour MCAO followed by 2-hour reperfusion. During MCAO, PKC levels increased in P2 and P3 in the most severe is

Inom ramen för Svenska kyrkans forskningsenhets projekt "I vems tjänst?", som är ett teologiskt aktionsforskningsprojekt om kyrka och välfärd, har under 2015 denna rapport arbetats fram för att ge en kunskapsöversiktom fält där kyrka och välfärd kopplas till varandra. Syftet med dennaförberedande undersökning är att bidra till underlag för att formulera frågeställningar och problem mer precist. Ra

The Benguela Upwelling System (BUS), located between 30 and 20°S, is one of the fundamental high-productivity systems of the world ocean. The BUS has previously been studied in terms of primary productivity and ecology over glacial-interglacial timescales; however, the response and coupling with the benthic environment have received little attention. Here, for the first time, we present a high-res

The tumor suppressor protein p53 is implicated in cell cycle arrest and DNA repair as well as in apoptosis. In the CNS, p53 has been associated with neuronal cell death following various insults, including cerebral ischemia. We investigated the expression of p53 messenger RNA and protein, and the messenger RNA expression of the p53-responsive gene p21(WAF1/Cip1), in specific hippocampal regions fo
