The purpose of this study was to analyze changes in the assemblage benthic macroinvertebrates, as a response anthropogenic environmental alterations river Extra-Andean Patagonia. Four sampling surveys were carried out between March 2017 and 2019, contrasting seasons on middle course Chico River (Santa Cruz). Six stations established: two reference upstream Gobernador Gregores town four downstre...

Using Mobile IP, a mobile node registers with its home agent each time it changes care-of address. This document describes a new kind of "regional registrations", i.e., registrations local to the visited domain. The regional registrations are performed via a new network entity called a Gateway Foreign Agent (GFA) and introduce a layer of hierarchy in the visited domain. Regional registrations r...

Previous research has reported a strong relationship between endorsing gambling as an escape and problem/pathological gambling as measured by the South Oaks Gambling Screen (SOGS). The present study recruited 249 university students to complete the Gambling Functional Assessment-Revised (GFA-R), which measures the function of the respondent's gambling, as well as the SOGS and the Problem Gambli...

The "Graphical Fragment Assembly" (GFA) is an emerging format for the representation of sequence assembly graphs, which can be adopted by both de Bruijn graph- and string graph-based assemblers. Here we present RGFA, an implementation of the proposed GFA specification in Ruby. It allows the user to conveniently parse, edit and write GFA files. Complex operations such as the separation of the im...

Brain cells from embryonic rats were dissociated with trypsin, cultivated under constant conditions in Falcon flasks, and studied for periods of one year or more. Antisera against glial fibrillary acidic protein (GFA) and myelin basic protein (MBP) were used to identify glial cell types. For scanning electron microscopical (SEM) observation an embedding method in resin was developed that allows...

Abstract Alloy melts can solidify into metallic glasses if cooled fast enough to avoid crystallization. Glass-forming ability (GFA), a measure of the ease vitrification, is vital for fundamental understanding glass formation, and also crucial application glasses. Previous studies GFA mainly focused on undercooled liquid phase, while influence evolution stable rarely addressed. Here we show that...

We explore the use of characteristic temperatures derived from molecular dynamics to predict aspects metallic Glass Forming Ability (GFA). Temperatures cooling curves self-diffusion, viscosity, and energy were used as features for machine learning models GFA. Multiple target model combinations with these explored. First, we logarithm critical casting thickness, log10(Dmax), trained regression o...

Little information exists about the possible neurotoxicity of styrene. The present study was designed to explore whether long term inhalation exposure (three months) to styrene (90 and 320 ppm) could induce long lasting astroglial alterations in Sprague Dawley rats, traceable four months after exposure ceased. Styrene exposure at 320 ppm induced such alterations as shown by raised concentration...

The next generation networks must support mobility for ubiquitous communication between any two nodes irrespective of their locations. Mobile IP was the first protocol to support mobility. The process of registration in Mobile IP protocol requires large number of location updates, excessive signaling traffic and service delay. This problem is solved by Hierarchical Mobile IP (HMIP) using the co...
