Abstract: This study aimed to evaluate the growth of young Phaseolus vulgaris (L.) plants exposed to air pollution in Sao Paulo. Between January and February 2010, for a period of 43 days, 40 young plants were exposed to several pollutants at two sites (Congonhas and Ibirapuera) located next to Cetesb air-quality monitoring stations having different pollution profiles. Subsequently, biometric readings of the plants' aerial organs were analyzed. A t-test statistical analysis was carried out in order to compare their growth between sites. Plants exposed at Ibirapuera grew more than those exposed at Congonhas, which can be explained by the reduced formation of ozone (the main local pollutant) in the former region, in addition to the range of other air contaminants that exist at the Congonhas station. The bean plants exhibited growth parameter alterations under conditions of environmental pollution.
Frequency and Energy Difference Detection of Dolphin Biosonar Signals Using a Decomposition Algorithm  [PDF]
Mark W. Muller
Open Journal of Acoustics (OJA) , 2016, DOI: 10.4236/oja.2016.61001
Abstract: A set of dolphin echolocation signals previously collected from an Atlantic bottlenose dolphin in Kaneohe Bay, Hawai’i are decomposed using a matching pursuit algorithm to further investigate the role of four types of echolocation signals outlined elsewhere [1]. The method decomposes the echolocation signals into optimal linear expansions of waveforms, which are Gabor functions defined in a dictionary. The method allows for study of the changes in frequency content within a dolphin’s functional bandwidth during discrimination tasks. We investigate the role of the functional bandwidth in terms of the signal energy levels and echolocations task performance. Furthermore, ROC analysis is applied to the relative energies of the matched waveforms to determine probability of discrimination. The results suggest that dolphins may discriminate by inspection of the relevant frequency differences between targets. In addition, the results from the ROC analysis provides insight into the role of the different classes of dolphin signals and of the importance of modification of the outgoing echolocation clicks, which may be fundamental to a dolphin’s ability to identify and discriminate targets.
Opening up das Schloβ: Creating Room for Thinking by Combining the Territorial Cohesion Discourse and the Debate on the European Union Polity  [PDF]
B. M. Hissink Muller
Art and Design Review (ADR) , 2016, DOI: 10.4236/adr.2016.43011
Abstract: To widen the debate about territorial cohesion, one can have a look at political science. We can namely critique the territorial cohesion discourse’s exclusion of reasoning about the political by showing the relevance of the simultaneous debate on the European Union polity. It thereby also comes forward that the concept’s power practices illustrate the bureaucratic, multi-level, polycentric, and network governance in flux that characterizes this polity. The territorial cohesion discourse might then exemplify how this opaque organization of governing leads to and is made possible by an associated form of expertise, which raises new questions on the role of social and spatial science in our society.
Isotropic shear bond strength behavior of superficial bovine dentin: A pilot study  [PDF]
Camila Sabatini, Sebastiano Andreana
Open Journal of Stomatology (OJST) , 2013, DOI: 10.4236/ojst.2013.31001

The aim of this pilot study was to evaluate the shear bond strength of superficial bovine incisor dentin in different crown regions. Bonding was performed to the incisal, middle and cervical thirds of superficial bovine coronal dentin (n = 20) with a two-step etch-and-rinse adhesive (Optibond Solo Plus) and resin composite (Z100). Shear bond strength was evaluated at 24 h and failure modes of representative specimens wereobserved with FE-SEM. Non-parametric Kruskal-Wallis test with a significance level of 0.05 was used for data analysis. Mean shear bond strength values for the incisal, middle, and cervical thirds were 36.9 (3.1), 42.6 (2.6), and 37.1 (2.1) respectively with no significant differences evidenced between the crown thirds (p = 0.19). Observation of the failure mode of representative specimens demonstrated that specimens with high bond strength values exhibited predominantly mixed-type failures whereas low strength specimens exhibited adhesive failures between the dentin and adhesive. The absence of significant differences in shear bond strength between crown thirds indicate that, regardless of tubule orientation, any crown region can be used when superficial bovine incisor dentin is used for shear bond strength testing.

Quality management: the key to achievement for the BreastScreen Australia Programme
J Muller
Breast Cancer Research , 2004, DOI: 10.1186/bcr828
Abstract: The Programme is underpinned by a quality management infrastructure with national and State/Territory roles and responsibilities. All BreastScreen Australia services must comply with National Accreditation Standards. To monitor quality at the service, State and National level, all services collect the National Minimum Dataset using the National Data Dictionary. Monitoring and Evaluation Plans are being implemented with annual reporting undertaken by the Australian Institute of Health and Welfare. A key evaluation project commissioned by the Programme is the mortality study.During the period 1996–2001 BreastScreen Australia screened over 4.5 million women, and has consistently maintained cancer detection rates and detection rates for small cancers at or above minimum standards set for services to achieve.Since the commencement of the BreastScreen Australia Programme there has been a 23.7% reduction in the death rate from breast cancer in women aged 50–69 years. The 5-year survival rate after diagnosis from breast cancer increased from 72.3% during 1982–1986 to 84% between 1992 and 1997.This presentation will outline of the quality management infrastructure and key achievements of BreastScreen Australia.
Reflexiones sobre O.V. y formación de orientadores en contextos de cambios globales
Orientaci?3n y sociedad , 1999,
Abstract: vocational guidance (v.g.) is currently facing both theoretical and methodological reconsiderations. this demands rethinking ethical and scientific assumptions, counselors' role and training. v.g. provides a space to receive information about oneself as well as about labor world and for the elaboration of projects for the future. many guidance situations in teenagers and young adults are described in this paper, highlighting the main current emergent aspects. there was a remarkable protagonism of those seeking guidance and the reflective frame of the guidance. this frame prepares for the educational stage changes and also for occupational insertion working on aspects that widen autonomous choice and the development of social abilities and attitudes to carry out the vocational project and the development in work. troubled sociocultural and economic transformations demand an on-going training on the part of counselors. to that end, possible fields of concern and subjects to be worked in said training are suggested.
