This paper focuses on carbon, which is one of the most abundant elements in the universe and is of high importance in the field of nucleosynthesis and galactic and stellar evolution. The origin of carbon and the relative importance of massive and low-to intermediate-mass stars in producing it is still a matter of debate. We aim at better understanding the origin of carbon by studying the trends of
PURPOSE: The presence of neovascular age-related macular degeneration (nAMD) in one eye is a major risk factor for the development of disease in the fellow eye. Several methods exist to help physicians monitor the fellow eye, with new technologies becoming increasingly available. METHODS: We provide an overview of modalities for nAMD monitoring, including advances in home-based options, and review
The study investigates the relationship between drought and vegetation variations in three main basins of western and southwestern of Iran, using the comprehensive approach of time-series analysis, Standardized Precipitation Index (SPI), and anomaly calculation. A total of 30 ground stations’ daily meteorological data and the MODIS 16-day composite NDVI products (2000–2017) were used in this case.
The silicon isotope composition of biogenic silica (δ30SiBSi) in the ocean is a function of the δ30Si of the available dissolved Si (DSi; H2SiO4), the degree of utilisation of the available DSi, and, for some organisms, the concentration of DSi. This makes δ30SiBSi in sediment archives a promising proxy for past DSi concentrations and utilisation. At steady-state, mean δ30SiBSi must equal a weight
This paper investigates the heterogeneity of the sources of external knowledge and their differentiated effects on process and product innovations respectively. The results of the empirical investigations show that the upstream vertical sources of external knowledge from suppliers exert a strong and positive role on the introduction of process innovations, whereas horizontal and downstream vertica
This monograph is a slightly revised version of my dissertation from 2005.
Automation is increasingly a part of everyday driving in systems such as adaptive cruise control (ACC) or collision warning systems. These systems are not perfect, meaning the driver has to stay vigilant for any faults or warnings, and be prepared to reclaim control. However, humans are not very good at monitoring well-functioning systems, meaning systems may need to offer more support than they c
The Cognitive Interview (CI) is a well-researched interview method and the research results show that CI, compared with more conventional interview styles, enhances witnesses’ memory. However, not much research has been done on the question of how CI affects the realism of eyewitnesses’ judgments of confidence in the veracity of their interview statements. In a previous study (Granhag, Jonsson &am
Large scale infrastructure developments means balancing of partly conflicting interests of economic growth, social cohesion, environmental impact etc. How this balancing is done when the project hits the local context is depending on the legislative framework, for instance through building permits environmental assessment. Still, there can be a big difference between the intentions of the law, and
TPA is known to cooperate with an activated Ras oncogene in the transformation of rodent fibroblasts, but the biochemical mechanisms responsible for this effect have not been established. In the present study we used c-fos promoter-luciferase constructs as reporters, in transient transfection assays, in NIH3T3 cells to assess the mechanism of this cooperation. We found a marked synergistic interac
