Out-of-home placement decisions in residential care are complex, ambiguous and full of uncertainty, especially in cases of parental neglect. Literature on this topic is so far unable to understand and demonstrate the source of errors involved in those decisions and still fails to focus on professional's decision making process. Therefore, this work intends to test a socio-psychological model of decision-making that is a more integrated, dualistic and ecological version of the Theory of Planned Behavior' ...

Abstract. This paper describes lightning characteristics as obtained in four sets of lightning measurements during recent field campaigns in different parts of the world from mid-latitudes to the tropics by the novel VLF/LF (very low frequency/low frequency) lightning detection network (LINET). The paper gives a general overview on the approach, and a synopsis of the statistical results for the observation periods as a whole and for one special day in each region. The focus is on the characteristics ...

Abstract. During the TROCCINOX field experiment in January and February 2005, the contribution of lightning-induced nitrogen oxides (LNOx) from tropical and subtropical thunderstorms in Southern Brazil was investigated. Airborne trace gas measurements (NO, NOy, CO and O3) were performed up to 12.5 km with the German research aircraft Falcon. During anvil penetrations in selected tropical and subtropical thunderstorms of 4 and 18 February, NOx mixing ratios were on average enhanced by 0.7–1.2 and 0. ...

The Humidity Sounder for Brazil (HSB) is a crucial component of the Atmospheric Infrared Sounder (AIRS) sounding suite and a valuable contribution from Brazil to the National Aeronautics and Space Administration's Aqua mission. Its design and functionality are practically identical to that of the Advanced Microwave Sounding Unit-B - proven on the latest National Oceanic and Atmospheric Administration's weather satellites. We briefly discuss its heritage, the measurement concept and principle of operation, ...

In this work a method is presented to obtain R-Zε relationships through comparison, in probability, of nonsimultaneous measurements of Zε and R. Range dependent relationships obtained in this way are given for a radar situated at 20°21′30″S, 49°01′38″W. The method is tested by comparing actual river hydrographs from a number of basins with those simulated using data as input to a hydrological model.

Objective. The aim of this study was to compare the behavior of two new, low-shrinkage hybrid composites (Aelite LS and Inten-S) with a microfilled (Heliomolar) and a hybrid composite (Filtek Z250), in terms of polymerization contraction stress and microleakage. Methods. Maximum contraction stress after 10 min was recorded in a 'tensilometer', using a C-factor (C) of 2.5 and energy density of 26 J/cm2. For the microleakage test, cylindrical cavities with enamel margins prepared in bovine incisors (4 mm ...

Convective storm rainfall is of special importance to urban hydrological studies due to its temporal and spatial variability. Although dense networks of recording rain gauges can be employed to characterize such rainfall, very few investigations of this type have been undertaken due to their prohibitive cost. This paper reports some data on characteristics of tropical convective storms obtained from radar at Bauru in the State of Sao Paulo, Brazil. Periods of convective precipitation were identified ...

Methods : Composite was photoactivated with 3, 6, 12, 24, or 48 J/cm 2 . Properties were measured after 48‐h dry storage at room temperature. DC was determined on the flat surfaces of 6 mm × 2 mm disk‐shaped specimens using FTIR. Flexural strength (FS) and modulus (FM) were accessed by three‐point bending. Knoop microhardness number (KHN) was measured on fragments of FS specimens. ...

The use of soft-start photoactivation to reduce shrinkage stress has become widespread in restorative dentistry. However, an increased susceptibility to ethanol degradation of polymers formed by pulse-delay photoactivation was reported. It was hypothesized that reductions in flexural strength after ethanol storage were related not only to low curing rates, but also to the radiant exposure employed. A commercial composite was subjected to different curing protocols (continuous at high irradiance, ...

In the present case series, the cause of death of infants diagnosed with congenital Zika syndrome (CZS) was lung disease (pneumonia and sepsis with massive pulmonary aspiration), probably secondary to dysphagia and reflux. The main findings in infants with a confirmed diagnosis of CZS who died were as follows: (1) calcification and hypoplasia of the lentiform nuclei, hypoplasia of the caudate nuclei, and calcification at the cortical-subcortical junction was noted in all cases (100%) and calcification ...

The aim of this study was to compare clinicopathological features between younger and older patients with GC in Northeastern Brazil. A total of 207 patients with distal GC (41 patients ≤45 years, considered younger group, and 166 > 45 years, considered older group) were evaluated prospectively during a 6 year period.

Satellite pictures have been utilised to detect mountain waves on the lee of the Andes range. The wavelengths as observed in the pictures from the distribution of clouds in parallel bands lie between 20 and 30 km for the five cases examined. The wavelengths have also been computed theoretically for these cases by an analytical method and a quasi-numerical method, using linearised perturbation equations. Wavelengths so computed are in fairly good agreement with the observed wavelengths, Vertical ...

Fibromyalgia (FM) has an inflammatory component, as elevated serum levels of inflammatory biomarkers are associated with its diagnosis. Treatments decreased pain, body temperature, improved quality of life and reduced serum levels of IL-6 in both groups; however, these beneficial effects were more pronounced in aquatic exercise (AE) + Far-Infrared (FIR) group. The findings of the present study suggest that the association of AE to FIR increases the benefits of aquatic exercise in patients with FM.

A case of melanotic neuroectodermal tumor of infancy (MNTI) in a 6-months-old white female child is presented. The tumor was located in the left half of the superior maxillary bone and affected the maxillary sinus, inducing large facial asymmetry. The histologic aspects of the tumor were typical for the entity: two cell populations, one pigmented melanocyte-like cell, the other small neuroblastic-like cell. After adjuvant chemotherapeutic treatment with a strong reduction of the tumor, the melanocyte- ...

The level of cytosolic glucocorticoid receptors (GR) was measured in 12 open-chest lung biopsies of interstitial pulmonary diseases. The results showed an increase in the GR content in the diseased lungs correlated to the degree of septal cellularity in nine cases. Two pulmonary sarcoidosis and one end-stage idiopathic pulmonary fibrosis patients presented higher levels of GR than those predicted by the septal cellularity. It was concluded that the GR content of the lungs increases in the course ...

The Bauru radar detects inner cores of deep convective storm cells at long range, but relevant cell areas are left undetected. A procedure is in development to generate a more complete three-dimensional representation of the cell structure for cost-beneficial hydrological use at larger distances. A set of satellite microwave brightness temperature (Tb)—radar reflectivity (Z) relationships, basic to the retrieval procedure, has been derived. Copyright © 2005 Royal Meteorological Society
