Perfil de estilo de vida individual de estudiantes de primer año de odontología de la Universidad de Aracatuba, Brasil - 2015

Introduction: Lifestyle is a factor related to the wellbeing of the individual which alters his or her morbidity and mortality. Objective: To analyze the lifestyle of young people who entered the dentistry program in 2015 and its association with demographic factors. Materials and methods: A cross-sectional analytical observational study was conducted with 114 first-year dental students. The data were collected with two instruments: Individual Lifestyle profile (ILP) which evaluated nutrition, physical activity, preventative behavior, social relationship and stress control; and a validated questionnaire that included sociodemographic variables, working condition and the departure from home on the basis of entering higher education. Maximum likelihood statistical tests and U of Mann-Withney were applied, considering a significance α = 0.05. Results: The majority of participants were women with an average age of 20.06 (± 2.65) and 18.96 (± 1.78) in the night and day courses, respectively. 81.57%, left home to enter the university and 7% carried out a paid activity. They presented an undesirable lifestyle profile in relation to nutrition, physical activity and stress control. Nutrition was influenced by the socioeconomic profile (P = 0.014). The consumption of alcohol and tobacco (p = 0.017) and the time dedicated to rest (P = 0.018) were significantly higher in students of in the night program. Conclusion: The lifestyle of young people who entered dentistry was not the desirable one. Living away from parents and the financial dependency of students are factors that affect their lifestyle

Factors affecting penicillium roquefortii (penicillium glaucum) in internally mould ripened cheeses: implications for pre-packed blue cheeses

The amount and vivid colour of blue veins of internally mould ripened cheeses are desirable quality characteristics. It is therefore important that there is a sufficient amount of veining and that it maintains its blue appearance to be appealing to consumers therefore leading to maximised sales potential and profit for the manufacturing company. Optimum in vitro growth mimicking the conditions typically found in prepacked blue cheeses, and using lactose as the sole carbon source, was facilitated by a gas mixture of 5% oxygen ⁄0% carbon dioxide ⁄ balance nitrogen). The work undertaken in this study determined that the factors for optimum in vitro growth of Penicillium roquefortii (strain PRB6) were: a temperature of 20 ± 1 �C, pH of 6.0 ± 0.1, and a relative humidity of 70 ± 0.1%. Further in vitro studies have also shown that the increasing ‘in-pack’ carbon dioxide concentration not only depresses the growth of P. roquefortii but also affects immature conidiospore pigmentation (no effect has been seen on mature conidiospore pigmentation). The implications of this study suggest that the majority of pre-packed internally mould ripened blue cheeses on sale in supermarkets are packaged in inappropriate materials. For some cheeses (e.g. the Roquefort-type cheeses) this is not an issue since these are packed in a much more mature state and some loss of veining colour is not appreciably noticeable

High-throughput sequencing reveals drastic changes in fungal communities in the phyllosphere of Norway spruce (Picea abies) following invasion of the spruce bud scale (Physokermes piceae)

The aim of this study was to assess the diversity and composition of fungal communities in damaged and undamaged shoots of Norway spruce (Picea abies) following recent invasion of the spruce bud scale (Physokermes piceae) in Lithuania. Sampling was done in July 2013 and included 50 random lateral shoots from ten random trees in each of five visually undamaged and five damaged 40-50-year-old pure stands of P. abies. DNA was isolated from 500 individual shoots, subjected to amplification of the internal transcribed spacer of fungal ribosomal DNA (ITS rDNA), barcoded and sequenced. Clustering of 149,426 high-quality sequences resulted in 1193 non-singleton contigs of which 1039 (87.1 %) were fungal. In total, there were 893 fungal taxa in damaged shoots and 608 taxa in undamaged shoots (p < 0.0001). Furthermore, 431 (41.5 %) fungal taxa were exclusively in damaged shoots, 146 (14.0 %) were exclusively in undamaged shoots, and 462 (44.5 %) were common to both types of samples. Correspondence analysis showed that study sites representing damaged and undamaged shoots were separated from each other, indicating that in these fungal communities, these were largely different and, therefore, heavily affected by P. piceae. In conclusion, the results demonstrated that invasive alien tree pests may have a profound effect on fungal mycobiota associated with the phyllosphere of P. abies, and therefore, in addition to their direct negative effect owing physical damage of the tissue, they may also indirectly determine health, sustainability and, ultimately, distribution of the forest tree species

Stability analysis of second order pulsed Raman laser in dispersion managed systems

8siWavelength tunable synchronous pulse sources are highly desirable for spectroscopy and optical diagnostics. The common method to generate short pulses in the fiber is the use of nonlinear induced spectral broadening which result in soliton shaping in anomalous dispersion regime. However, to generate ultra-short pulses, broadband gain mechanism is also required. In recent years, Raman fiber lasers have retrieved strong interest due to their capability of serving as pump sources in gain-flattened amplifiers for optical communication systems. The fixed-wavelength Raman lasers have been widely studied in the last years, but recently, much focus has been on the multi wavelength tunable Raman fiber lasers which generate output Stokes pulses in a broad wavelength range by so called cascaded stimulated Raman scattering. In this paper we investigate synchronous 1st and 2nd order pulsed Raman lasers that can achieve frequency spacing of up to 1000cm-1 that is highly desired for CARS microscopy. In particular, analytical and numerical analysis of pulsed stability derived for Raman lasers by using dispersion managed telecom fibers and pumped by 1530nm fiber lasers. We show the evolution of the 1st and 2nd order Stokes signals at the output for different pump power and SMF length (determines the net anomalous dispersion) combinations. We investigated the stability of dispersion managed synchronous Raman laser up to second order both analytically and numerically. The results show that the stable 2nd order Raman Stokes pulses with 0.04W to 0.1W peak power and 2ps to 3.5ps pulse width can be achieved in dispersion managed systemopenopenS. K. Kalyoncu; S.

Plieno plaušu armuotų gelžbetoninių sijų tinkamumo ribinio būvio analizė

In last decades, the use of steel fibre reinforced concrete (SFRC) as a construction material has developed beyond the traditional applications. Despite the notable research advances in the fibre reinforcement technology and the development of guidelines and recommendations for structural design, questions continue to arise regarding the characterization and modelling of SFRC. The definition of the constitutive models of SFRC and the development of methods for the prediction of deformation and cracking of SFRC structural elements either without or with a traditional bar reinforcement have been extensively studied by many researchers, though their adequacy for certain applications still remains an issue. These subjects require further research in order to work towards an accurate and efficient design procedure. This thesis investigates the deformation and cracking behaviour of SFRC beams with and without steel bars. Special attention is paid for the analysis of residual strength of tensile SFRC – the fundamental material characteristic for analysis of SFRC structures. With the aim of identifying the residual strength responses, an extensive experimental investigation of 48 flexural SFRC elements subjected to three- and four-point loading is executed. A simple technique for prediction of residual strength from standard three-point bending test is proposed. The main advantage of the proposed technique (in comparison with the standard methods) is its capability to calculate residual strength of tensile SFRC at any given loading or deflection. For prediction of deformation and cracking behaviour of SFRC beams with bar reinforcement a numerical simulation algorithm is developed. Unlike the most of the serviceability techniques that are used specifically either for deformation or crack analysis, the algorithm based on the stress-transfer approach allows to sim-ultaneously model both the deflection and cracking response of SFRC beams with bar reinforcement. In addition to the residual strength, the laws characterising bond-slip and damage zone are the basic constitutive parameters governing the results of analysis. Being mechanically sound, the developed technique can be universally applied to any type of concrete (plain, high strength/performance) and reinforcement (steel, fibre reinforced polymer). To evaluate the adequacy of the developed technique, an experimental program consisting of 11 full scale reinforced concrete beams with varying fibre content was performed. Comparison of numerical and experimental results proved the applicability of the proposed modelling method. The author have published 14 articles on the topic of the dissertation (5 of them in the journals with an Impact Factor and 3 in the conference proceedings referred by the Clarivate Analytics Web of Science database)
