Abstract: objectives: the objectives of this study were to assess the fluoride concentration in the public water supply and the prevalence of dental fluorosis in schoolchildren between 7 and 15 years old, living in a peripheral district of the municipality of bauru. material and methods: for this, fifty two water samples were collected on three different days of one week. these samples were analyzed for fluoride by means of the ion-sensitive electrode method (orion 9609) coupled to a potentiometer (procyon, model 720). in this method, 1.0 ml of tisab ii (orion) was added to 1.0 ml of the sample. for the epidemiological survey of fluorosis, 52 schoolchildren of both genders, aged between 7 and 15 were assessed, with prior authorization from their caretakers. only one person examined the children, after supervised toothbrushing and drying with cotton wool rolls. the tf index was used. results: the fluoride concentrations in the water samples ranged from 0.62 to 1.20 mg/l, with a mean of 0.9 mg/l. the prevalence of dental fluorosis was 33%, with severity ranging from tf1 to tf4 (kappa of 0.73 and concordance of 83.33%). conclusions: the results from the analysis of water samples indicated a fluoride concentration greater than recommended for bauru. the fluorosis levels found were higher than expected for a peripheral district, in which water is one of the few sources of fluoride.
Conscious Use of the Virtual Sphere Modeling in the Simulation of Passive Night Cooling of Buildings  [PDF]
Marco Simonetti
Open Journal of Energy Efficiency (OJEE) , 2016, DOI: 10.4236/ojee.2016.52006
Abstract: Night cooling of building is considered as a technology with a high potential of impact on air conditioning energy needs. Natural ventilation should be the first option for night cooling, for obvious reasons of energy savings. The evaluation of the capacity of the building to cool down its structures during night ventilation is of primary concern during preliminary design stage, even though night cooling with natural ventilation is among the most complex problem to be modelled in details. Some modelling options are available, assuming different simplifications in space and time. Among them, virtual sphere modelling has been proposed in the past as a quick way to perform dynamic simulation of the night cooling of buildings. In this paper, the theoretical origin of the virtual sphere model is recalled, underlining its limits in case of application to buoyancy driven night cooling of buildings. The limits can explain the disagreements of virtual sphere prediction with other methods reported in literature and may stimulate a more conscious application of the model and further improvements of the method.

Abstract: based on the multidimensional model proposed by marsh and shavelson (1985), this study tries to verify in what manner different level of sport participation (people who never play sport; abandoned sport and still plays sport) are associated to different self-concept structures. simultaneously, the study pretends to access how sport participation is related with different levels in the various domains of self-concept. the portuguese version of sdq iii (faria & fontaine, 1992) was administrated to 218 subjects (male and female), with ages between 17 and 35 years, non-praticants (n=69), past-praticants (n=72) and praticants (n=77) of different kind of sport. the differences between these groups in differents domains of self-concept were analyse, well as the differences between gender and age were explored. the results revealed that global self-concept was higher in sport participants and that men and women differ significantly in terms of physical appearance and competence.

Abstract: the objective of this paper was to determine in what manner a training program of modelling and mental imagery (during two weeks) could affect the self-efficacy expectations and performance of an group of athletes from artistic skating. the subjects (19 girls) were distributed to one of three experimental conditions: control group (n=7), experimental group (n=6), with a training program of modelling; and a second experimental group (n=6) with a training program of modelling plus a program of mental imagery. the results showed that the experimental groups didn't improve the self-efficacy expectations and performance during the two weeks of study. however, despite the sample's dimension limitations and the short-length of the program (two weeks) it was possible to establish that: (a) the self-efficacy expectations showed to be better predictors of performance than the outcome expectations; (b) the past performance plays an important role in formation of self-efficacy; (c) the experimental programs improved the self-perception of athletes regarding the level of performance that could accomplish attending the motor and technical skills which they had in the beginning of the program.

Abstract: the aim of this in vitro study was to evaluate the erosive capacity of fermented milk beverages, as well as some of their properties that affect the demineralization of dental enamel (ph, buffering capacity, fluoride, calcium and phosphorus contents). three different batches of 6 commercial brands of fermented milk beverages were analyzed. ph evaluation was accomplished using a potentiometer. the buffering capacity was measured by adding 1 mol l-1 naoh. fluoride concentration was assessed by an ion specific electrode after hexamethyldisiloxane-facilitated diffusion, and calcium and phosphorus concentrations were assessed by a colorimetric test using a spectrophotometer. sixty specimens of bovine enamel were randomly assigned to 6 groups (n = 10). they were exposed to 4 cycles of demineralization in the fermented milk and remineralization in artificial saliva. enamel mineral loss was determined by surface microhardness (%smhc) and profilometric tests. the samples' ph ranged from 3.51 to 3.87; the buffering capacity ranged from 470.8 to 804.2 μl of 1 mol l-1 naoh; the fluoride concentration ranged from 0.027 to 0.958 μgf/g; the calcium concentration ranged from 0.4788 to 0.8175 mgca/g; and the phosphorus concentration ranged from 0.2662 to 0.5043 mgp/g. the %smhc ranged from -41.0 to -29.4. the enamel wear ranged from 0.15 μm to 0.18 μm. in this in vitro study, the fermented milk beverages did not promote erosion of the dental enamel, but rather only a superficial mineral loss.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0061036
Abstract: It is not known whether rainfall increases the risk of sporadic cases of Legionella pneumonia. We sought to test this hypothesis in a prospective observational cohort study of non-immunosuppressed adults hospitalized for community-acquired pneumonia (1995–2011). Cases with Legionella pneumonia were compared with those with non-Legionella pneumonia. Using daily rainfall data obtained from the regional meteorological service we examined patterns of rainfall over the days prior to admission in each study group. Of 4168 patients, 231 (5.5%) had Legionella pneumonia. The diagnosis was based on one or more of the following: sputum (41 cases), antigenuria (206) and serology (98). Daily rainfall average was 0.556 liters/m2 in the Legionella pneumonia group vs. 0.328 liters/m2 for non-Legionella pneumonia cases (p = 0.04). A ROC curve was plotted to compare the incidence of Legionella pneumonia and the weighted median rainfall. The cut-off point was 0.42 (AUC 0.54). Patients who were admitted to hospital with a prior weighted median rainfall higher than 0.42 were more likely to have Legionella pneumonia (OR 1.35; 95% CI 1.02–1.78; p = .03). Spearman Rho correlations revealed a relationship between Legionella pneumonia and rainfall average during each two-week reporting period (0.14; p = 0.003). No relationship was found between rainfall average and non-Legionella pneumonia cases (?0.06; p = 0.24). As a conclusion, rainfall is a significant risk factor for sporadic Legionella pneumonia. Physicians should carefully consider Legionella pneumonia when selecting diagnostic tests and antimicrobial therapy for patients presenting with CAP after periods of rainfall.
Adaptation and Validation of a Proteolytic Activity Methodology Using Dye-Crosslinked Substrate Tablets  [PDF]
Fernanda Martins, Elaine C. Ramires
Advances in Enzyme Research (AER) , 2014, DOI: 10.4236/aer.2014.23012
Abstract: Enzymatic activities are important to be quantified in products as enzymatic cleaners, which are used in medical and surgical devices reprocessing. Enzymatic activities are critical for the proper chemical cleaning that intends to remove solid organic dirt from inaccessible sites. The most important enzyme for this purpose is the protease, which is able to dissolve the main dirt attached to medical and surgical instruments. In this context, this study contributes to the development of a new proteolytic activity quantification method and its validation. The methodology is based on colorimetry and uses a UV-Vis spectrophotometer to measure the substrate hydrolysis by the blue color intensity, employing Protazyme AK tablets as substrate.
Le service militaire et la condition des femmes en Isra l

Abstract: Military Service and Women’s Conditions in Israel: Some Elements of ReflectionWomen’s condition in Israel finds his roots in several factors: cultural, socio-economical, religious as a reflection of the complexity of people in this country. The geopolitical situation, linked to the state of war of Israel, also affect women’s life in Israel. Israel is one of the few countries, and the only western country in the world, that drafts women in the army compulsory service. In particular this element creates interesting paradoxes between women’s contribution to the defence of the country, the status traditionally attributed to them and their own path to emancipation in the Israeli society.The Israeli Defence Force (IDF) is a central institution for the Israeli society. IDF draws the societal hierarchy in the State, determines the attribution of resources and it represents a way of access to the political arena in Israel. Responding to the national duties, among which the compulsory service is the highest expression, is what makes one a good citizen. But in Israel a wide cleavage between women and men is perpetrated in the army and into the military organisation itself. By consequence the gender division in the army is reproduced in civil life as well. Women serve in the army for a shorter period of time, their contribution, for most of them, is reduced to female work and, once freed by the army duty, they do not enjoy socio-economical opportunities as men do. Many feminists and that part of the women movements which had more influence in the Parliament, started to focus their attention on the achievement of a wider range of jobs and positions for women in the army. These last decades have seen important changes in the Israeli army that have modified its structure in particular concerning the gender relations and the women’s role in the military. The opening of flight courses for officers to women was an important starting point as well as the opening of combat units. The second Lebanon war has seen for the first time, since the birth of the Israeli Nation, women’s operational participation during a conflict. This marks a big change for the Israeli army, which may lead to a new balance of opportunities between women and men and a transformation of the classical roles attributed to women and their public participation in social and political life in Israel. In order to understand the social and gender implications of the presence of women in the army, the article will start considering the meaning of the compulsory service in Israel at the light of the centrality
