The transition from traditional paper libraries to digital libraries enables new strategies for the use and maintenance of artifact collections. Distributed software development can be regarded as a special case of digital library utilization, where developers or groups of developers are working on the same software geographically dispersed in time zones which might differ. We present a hierarc...

The mammalian neocortex is composed of two major neuronal cell types with distinct origins: excitatory pyramidal neurons and inhibitory interneurons, generated in dorsal and ventral progenitor zones of the embryonic telencephalon, respectively. Thus, inhibitory neurons migrate relatively long distances to reach their destination in the developing forebrain. The role of lineage in the organizati...

This paper investigates the impact of Computer Mediated Communication (CMC) in distributed teams on real or perceived Information Overload (IO). Typically, these organizations rely on CMC for communication because teams working on joint projects are spatially dispersed and have to communicate across space and time zones. Many of the problems observed in virtual teams seem to be related to commu...

Revealing prospective locations of hydrothermal alteration zones (HAZs) is an important technique for mineral prospecting. In this study, we used multiple criteria inferred from Landsat-8 OLI, Sentinel-2, and ASTER data using a GIS-based weighted overlay multi-criteria decision analysis approach to build model the delineating deposits in Khnaiguiyah district, Saudi Arabia. The utilized algorith...

Abstract Turfgrass with sand‐based root zones, such as golf course putting greens, are highly important economically and require intense management. However, problems often associated low nutrient retention limited microbial activity. Soil additives may increase soil biological activity, improve nitrogen (N) cycling efficiency, thus reduce fertilizer N inputs. A 2‐yr experiment was conducted on...

The paper presents the results of comprehensive isotope geochemical (Re-Os, Pb and ?34S) study sulfide mineralization Morozkinskoye deposit. ore zones deposit are localized in syenite massif Mount Rudnaya, which is located within Central Aldan region (southern Yakutia). Gold represented by vein-disseminated or vein type manifested acidic low-temperature metasomatites – beresites (Qz-Ser-Ank-Py)...

[1] The allochthonous supply of dissolved organic nitrogen (DON) from gyre margins into the interior of the ocean’s oligotrophic subtropical gyres potentially provides an important source of new N to gyre surface waters, thus sustaining export production. This process requires that a fraction of the transported DON be available to euphotic zone photoautotroph communities via mineralization. In ...

This study investigates the application of models traditionally used to estimate erosion and sediment deposition to assess the potential risk of water quality impairment resulting from metal-bearing materials related to mining and mineralization. An integrated watershed analysis using Geographic Information Systems (GIS) based tools was undertaken to examine erosion and sediment transport chara...
