Biome-networks: Information And Communication For Sociopolitical Action In Eco-regions

Since ECO-92, environmental organizations and social movements have been networking with the support of information and communication technologies, in order to strengthen their capacity to influence decision-making processes relating to the causes they fight for. Some of these networks have been organized around the six Brazilian official biomes and have been incorporating the resources available on the Internet to achieve greater public visibility, capillarity and communicative effectiveness on their strategic actions. However, not all of them have been able to remain updated, active and visible in the increasingly dynamic digital environment, despite its informational and political legacy. This paper presents a synthesis of a comparative research among the here called "biome-networks", based on data collection on its organizational structures and its informational and communicative resources used to achieve its strategic aims related to the eco-regions in which they operate.19323124

Evaluate and Intervene in Sensory Processing Disorders by Occupational Therapists in Early Intervention Teams of the North of Portugal

Background: The National Early Childhood Intervention System of Portugal is an organized set of services under the responsibility of the Ministries of Health, Labor, and Social Security and Education aimed to support children between 0 and 6 years old and their families, and its mission is to ensure Early Childhood Intervention. At present, there is no research to support the extent of the use of sensory interventions in early intervention teams of Portugal. Aims: This study aims to analyze and understand the role of occupational therapists who support children with Sensory Processing Dysfunction and their families in local Early Intervention Teams. Methods: A qualitative and descriptive research was developed using semi-structured interviews. The interviews were conducted with ten occupational therapists who have worked in Early Intervention Teams in the North of Portugal for at least one year. Results: Modulation and Praxis were the categories of Sensory Processing Dysfunction most identified. Families consider that Sensory Processing Dysfunctions interfere with children's performance in activities of daily living and playing. Early childhood educators report that Sensory Processing Dysfunctions influence the child's participation in food, playing, and in more structured and directed activities. To transfer skills, occupational therapists organize training for professionals, families, and early childhood educators. Conclusion: The importance of collaborative work between professionals and the child's family is evident, and the support they provide in the natural environment and daily routines

Retarding field energy analyzers for ion temperature measurements in the boundary plasmas of the tokamak ISTTOK and TJ-II stellarator

The retarding field energy analyzer (RFEA) remains the more reliable diagnostic to measure the ion temperature in the boundary plasmas of magnetic fusion devices. A compact, simple design RFEA have been developed for investigations on the tokamak ISTTOK and TJ-II stellarator. More recently a five-channel RFEA has been successfully tested allowing the simultaneous measurement of the ion temperature profile. The conditions of the RFEA operation in poor alignment along magnetic field are considered.Аналізатор енергії з затримуючим потенціалом (АЕЗП) залишається найбільш надійним діагностичним пристроєм для виміру температури іонів поблизу границі плазми термоядерних установок з магнітним утриманням.

Dendrimer Stabilized Nanoalloys for Ink-Jet Printing of Surface-Enhanced Raman Scattering Substrates

Research on paper substrates prepared by inkjet deposition of metal nanoparticles for sensing applications has become a hot topic in recent years; however, the design of such substrates based on the deposition of alloy nanoparticles remains less explored. Herein, we report for the first time the inkjet printing of dendrimer-stabilized colloidal metal nanoalloys for the preparation of paper substrates for surface-enhanced Raman scattering (SERS) spectroscopy. To this end, nanoassemblies containing variable molar ratios of Au:Ag were prepared in the presence of poly(amidoamine) dendrimer (PAMAM), resulting in plasmonic properties that depend on the chemical composition of the final materials. The dendrimer-stabilized Au:Ag:PAMAM colloids exhibit high colloidal stability, making them suitable for the preparation of inks for long-term use in inkjet printing of paper substrates. Moreover, the pre-treatment of paper with a polystyrene (PS) aqueous emulsion resulted in hydrophobic substrates with improved SERS sensitivity, as illustrated in the analytical detection of tetramethylthiuram disulfide (thiram pesticide) dissolved in aqueous solutions. We suggest that the interactions established between the two polymers (PAMAM and PS) in an interface region over the cellulosic fibres, resulted in more exposed metallic surfaces for the adsorption of the analyte molecules. The resulting hydrophobic substrates show long-term plasmonic stability with high SERS signal retention for at least ninety days.publishe

Towards stellar effective temperatures and diameters at 1 per cent accuracy for future surveys

The apparent size of stars is a crucial benchmark for fundamental stellar properties such as effective temperatures, radii and surface gravities. While interferometric measurements of stellar angular diameters are the most direct method to gauge these, they are still limited to relatively nearby and bright stars, which are saturated in most of the modern photometric surveys. This dichotomy prevents us from safely extending well-calibrated relations to the faint stars targeted in large spectroscopic and photometric surveys. Here, we alleviate this obstacle by presenting South African Astronomical Observatory near-infrared JHK observations of 55 stars: 16 of them have interferometric angular diameters and the rest are in common with the 2 Micron All Sky Survey (2MASS, unsaturated) data set, allowing us to tie the effective temperatures and angular diameters derived via the infrared flux method to the interferometric scale. We extend the test to recent interferometric measurements of unsaturated 2MASS stars, including giants, and the metal-poor benchmark target HD122563. With a critical evaluation of the systematics involved, we conclude that a 1 per cent accuracy in fundamental stellar parameters is usually within reach. Caution, however, must be used when indirectly testing a Teff scale via colour relations as well as when assessing the reliability of interferometric measurements, especially at submilliarcsec level. As a result, rather different effective temperature scales can be compatible with a given subset of interferometric data. We highlight some caveats to be aware of in such a quest and suggest a simple method to check against systematics in fundamental measurements. A new diagnostic combination seismic radii with astrometric distances is also presented.</p

Stretched Horizon and Entropy of Superstars

Amongst the class of supergravity solutions found by Lin, Lunin and Maldacena, we consider pure and mixed state configurations generated by phase space densities in the dual fermionic picture. A one-to-one map is constructed between the phase space densities and piecewise monotonic curves, which generalize the Young diagrams corresponding to pure states. Within the fermionic phase space picture, a microscopic formula for the entropy of mixed states is proposed. Considering thermal ensembles, agreement is found between the thermodynamic and the proposed microscopic entropies. Furthermore, we study fluctuations in thermodynamic ensembles for the superstar and compare the entropy of these ensembles with the area of stretched horizons predicted by the mean fluctuation size.Comment: 21 pages, 3 figures, 2 references adde

Chiral phase boundary of QCD at finite temperature

We analyze the approach to chiral symmetry breaking in QCD at finite temperature, using the functional renormalization group. We compute the running gauge coupling in QCD for all temperatures and scales within a simple truncated renormalization flow. At finite temperature, the coupling is governed by a fixed point of the 3-dimensional theory for scales smaller than the corresponding temperature. Chiral symmetry breaking is approached if the running coupling drives the quark sector to criticality. We quantitatively determine the phase boundary in the plane of temperature and number of flavors and find good agreement with lattice results. As a generic and testable prediction, we observe that our underlying IR fixed-point scenario leaves its imprint in the shape of the phase boundary near the critical flavor number: here, the scaling of the critical temperature is determined by the zero-temperature IR critical exponent of the running coupling.Comment: 39 pages, 8 figure

Action of phosphorylated mannanoligosaccharides on immune and hematological responses and fecal consistency of dogs experimentally infected with enteropathogenic Escherichia coli strains

The therapeutic action of phosphorylated mannanoligosaccharides (MOS) was investigated regarding its prebiotic activity on enteropathogenic Escherichia coli (EPEC). Diarrhea was induced in dogs by experimental infection with EPEC strains. Then MOS was supplied once a day, in water for 20 days. Immunological (IgA and IgG), hematological (lymphocytes, neutrophils and monocytes) and bacteriological variables (PCR detection of the eae gene of EPEC recovered from stool culture), as well as occurrence of diarrhea were evaluated. All strains caused diarrhea at 24, 48 and 72 h after infection. PCR results indicated that E. coli isolated from stool culture of all infected animals had the eae gene. There was no significant difference among groups as to number of blood cells in the hemogram and IgA and IgG production. MOS was effective in recovering of EPEC-infected dogs since prebiotic-treated animals recovered more rapidly from infection than untreated ones (p < 0.05). This is an important finding since diarrhea causes intense dehydration and nutrient loss. The use of prebiotics for humans and other animals with diarrhea can be an alternative for the treatment and prophylaxis of EPEC infections
