Spatial analysis of caries experience in population of teens, adults, and elderly people in the state of São Paulo : data from SB SP 2015

Estimate the prevalence and gravity of coronal dental caries for populations of adolescents, adults and elderly people. For the crossing of data of the average DMF rates by Regional Health Directorate (RHD) with the digital cartographical base, municipals were grouped by RHD, and the connection between the two bases was formed by a common code or "primary key" in the TerraView® software program (version 4.2.1). The distribution of the DMF average for the teen population was the worst for RHD 8, while RHDs 4, 7 and 14 had lower averages. For the adult population, RHDs 4 and 12 presented the lowest DMF averages. On the other hand, RHDs 8, 13, and 16 had the worst results. For the elderly population, the RHD 4 presented the lowest average, and RHD 9 the highest DMF rate for this population. The differences in DMF averages among the RHDs and the populations studied showed that it is necessary to plan different locoregional oral health actions to face the severe clinical state exposed, since its spatial distribution is disparate, with concentrations of cases in certain regions for all age groups studied3311621CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP0966/1514/50109-

Thermostatistics of deformed bosons and fermions

Based on the q-deformed oscillator algebra, we study the behavior of the mean occupation number and its analogies with intermediate statistics and we obtain an expression in terms of an infinite continued fraction, thus clarifying successive approximations. In this framework, we study the thermostatistics of q-deformed bosons and fermions and show that thermodynamics can be built on the formalism of q-calculus. The entire structure of thermodynamics is preserved if ordinary derivatives are replaced by the use of an appropriate Jackson derivative and q-integral. Moreover, we derive the most important thermodynamic functions and we study the q-boson and q-fermion ideal gas in the thermodynamic limit.Comment: 14 pages, 2 figure

EFFECT OF CHARCOAL -ENRICHED SUBSTRATE ON SEEDLINGS OF RHIZOBIUM-INOCULATED LEGUME TREES

ABSTRACT Native legume trees are planted in agroforestry systems for their hardiness and symbiosis with soil bacteria of the genus rhizobium, efficient in N2 fixation. The enrichment of the substrate composition with fine charcoal for seedling production of these trees is interesting for increasing soil porosity, water retention and the proliferation of beneficial microorganisms. Experiments were carried out to analyze the effect of substrate enrichment with charcoal on the quality of Clitoria fairchildiana, Enterolobium schomburgkii and Inga edulis seedlings. The treatments consisted of a 3:2:0.5 (v:v) mixture of clay soil, sand and bovine manure and a 3:2 (v:v) mixture of clay soil and sand combined with charcoal rates of 0, 10, 19 and 29%. After mixing the components, substrate samples were collected and chemically analyzed. The experiment was arranged in a completely randomized design with 5 treatments and 10 replications. The seedlings were inoculated with homologues rhizobia and growth controlled monthly. The plants were collected to determine the number of nodules and dry biomass of roots, shoots and nodules. Seedling growth was similar on substrates containing charcoal or manure, except for E. schomburkii, which increased by more than 100% on the charcoal-containing substrates. The number and dry biomass of nodules in the charcoal-containing substrates was up to 100% and 300% higher than in the manure-containing treatment, respectively. The results indicated that the substitution of manure by charcoal favors the seedling quality of the studied species
