According to theoretical considerations, multiplicity of hierarchical stellar systems can reach, depending on masses and orbital parameters, several hundred, while observational data confirm the existence of at most septuple (seven-component) systems. In this study, we cross-match the stellar systems of very high multiplicity (six and more components) in modern catalogues of visual double and multiple stars to find among them the candidates to hierarchical systems. After cross-matching the catalogues of closer binaries (eclipsing, spectroscopic, etc.), some of their components were found to be binary/multiple themselves, what increases the system's degree of multiplicity. Optical pairs, known from literature or filtered by the authors, were flagged and excluded from the statistics. We compiled a list of hierarchical systems with potentially very high multiplicity that contains ten objects. Their multiplicity does not exceed 12, and we discuss a number of ways to explain the lack of extremely high multiplicity systems.
Visual Binary Stars: Data to Investigate Formation of Binaries

Published: March 2017

Statistics of orbital parameters of binary stars as well as statistics of their physical characteristics bear traces of star formation history. However, statistical investigations of binaries are complicated by incomplete or missing observational data and by a number of observational selection effects.

Visual binaries are the most common type of observed binary stars, with the number of pairs exceeding 130 000. The most complete list of presently known visual binary stars was compiled by cross-matching objects and combining data of the three largest catalogues of visual binaries. This list was supplemented by the data on parallaxes, multicolor photometry, and spectral characteristics taken from other catalogues. This allowed us to compensate partly for the lack of observational data for these objects. The combined data allowed us to check the validity of observational values and to investigate statistics of the orbital and physical parameters of visual binaries. Corrections for incompleteness of observational data are discussed. The datasets obtained, together with modern distributions of binary parameters, will be used to reconstruct the initial distributions and parameters of the function of star formation for binary systems.

Authors: Poulopoulos Athanasios , Iordanidis Fotios , Andreadis Dimitrios , Antoniadis Konstantinos
Published: March 2017

Background: Myeloid sarcoma (MS) is a solid malignant tumour associated with infiltration of immature myeloid precursor cells in an extramedullary site. The term MS has replaced the term granulocytic sarcoma and chloroma, which were used in the past. MS in the oral cavity is very uncommon, with less of 40 cases reported until recently. Case Report: We report the first case, the features, and the diagnostic sequence, of intraoral MS with bilateral palatal involvement, which presented as an initial manifestation, and preceded the appearance of acute myeloid leukemia (AML). Diagnostic confirmation of such oral mucosal lesions usually requires biopsy, histopathological examination with additional immunohistochemical investigation. MS can occur during the course of acute or chronic myelogenous leukemia, and myelodysplastic syndromes. In the vast majority of the reported cases, only one site was involved with a single intraoral MS lesion, and the cases predominantly associated with AML. Conclusion: The majority of intraoral MS occurs in patients with known AML, but in some of them, presented as an initial manifestation, and preceded the appearance of the disease. Therefore, clinicians should carefully evaluate all unusual oral lesions of unknown origin.

Published: March 2017

In order to evaluate the effect of irrigation interval on yield and quantitative-qualitative characteristics of bread wheat, splited plot experiment in randomized block with four replications in the 2010-11 crop years was conducted in the research field of Islamic Azad University of Gonabad. A number of 7, 9 and 10 days irrigation treatments formed the main factors of test, and spraying and non-spraying of nitrogen and zinc were considered as subfactor of test. The results showed that the effect of irrigation was significant for the number of grains per spike in the level of 5% and on 1000-grain weight and fat percent at the level of 1%, and had no significant effect on grain yield, biological yield, number of spikes/sq m stem height, stem diameter and protein content. Nitrogen treatment was significant at the level of 5% on biological yield and number of spikes/sq m, but had no significant effect on grain yield, number of grains per spike, 1000-grain weight, stem height, fat and protein percent, and stem diameter. Treatment with zinc was statistically significant in probability level of 1% only on percentage of fat and had no significant effect on grain yield, biological yield, grain numbers per spike, weight of 1000 seeds, spikes/sq m, stem height, protein percent and stem diameter. Seven days irrigation with of nitrogen allocated for highest seed yield (265.38 g/m2/sq m) and biological yield (659.33 g/m2/sq m). Means comparison showed the highest 1000-grain weight was obtained from 7 days irrigation (47.10 g) and the lowest from 13 days irrigation (40.44 g). According to the experiment results, 7 days irrigation was recognized as the best irrigation to achieve maximum economic performance and 13 days irrigation were determined as most appropriate irrigation for maximum performance for the region due to lack of water and weather conditions of Gonabad, spraying zinc and nitrogen to improve production was proposed depending on different irrigation and the purpose of production.

Published: March 2017

Quantitative mass spectrometry approaches are used for absolute and relative quantification in global proteome studies. To date, relative and absolute quantification techniques are available that differ in quantification accuracy, proteome coverage, complexity and robustness. This review focuses on most common relative or absolute quantification strategies exemplified by three experimental studies. A label-free relative quantification approach was performed for the investigation of the membrane proteome of sensory cilia to the depth of olfactory receptors in Mus musculus. A SILAC-based relative quantification approach was successfully applied for the identification of core components and transient interactors of the peroxisomal importomer in Saccharomyces cerevisiae. Furthermore, AQUA using stable isotopes was exemplified to unraveling the prenylome influenced by novel prenyltransferase inhibitors. Characteristic enrichment and fragmentation strategies for a robust quantification of the prenylome are also summarized.

Published: March 2017

Data mining techniques support numerous applications of intelligent transportation systems (ITSs). This paper critically reviews various data mining techniques for achieving trip planning in ITSs. The literature review starts with the discussion on the contributions of descriptive and predictive mining techniques in ITSs, and later continues on the contributions of the clustering techniques. Being the largely used approach, the use of cluster analysis in ITSs is assessed. However, big data analysis is risky with clustering methods. Thus, evolutionary computational algorithms are used for data mining. Though unsupervised clustering models are widely used, drawbacks such as selection of optimal number of clustering points, defining termination criterion, and lack of objective function also occur. Eventually, various drawbacks of evolutionary computational algorithm are also addressed in this paper.

Published: March 2017

Transport properties in gases are significantly affected by temperature. In previous works it has been shown that when the thermal agitation in a gas is sufficient for relativistic effects to become relevant, heat dissipation is driven not solely by a temperature gradient but also by other vector forces. In the case of relativistic charged fluids, a heat flux is driven by an electrostatic field

Published: March 2017

The formation mechanism of regularly arranged tubular pores during an acid-based electrophoretic deposition (EPD) process was explored by studying the influence of gauze electrodes and suspension properties on the pore structures. The gauze electrodes can change the intensity of electrical field on the electrode surface, and thus control the pore locations. The mesh size not only restricts the ultimate pore size, but also determines the regularity of the pores. Under specific experimental conditions, a critical value of mesh size for attaining the regularity of the pores arrangement can be determined. Meanwhile, the pore structures can be controlled by a combination of pH value and zeta potential of the suspensions. The strength of the acidity is also one of the determinants to the final structures.
90Sr in Zostera marina from the Gulf of Gdańsk (southern Baltic Sea)
Authors: Saniewski Michał , Zalewska Tamara
Published: March 2017

90Sr activity was determined in Zostera marina collected in the Gulf of Gdańsk in 2008-2013. 90Sr activity in Z. marina from Jama Kuźnicka and Klif Orłowski range from 0.83 Bq kg−1 d.w. to 3.78 Bq kg−1 d.w. and from 0.68 Bq kg−1 d.w. to 4.95 Bq kg−1 d.w., respectively. The plants collected in spring-summer showed significant differences between 90Sr content in blades - 1.55 Bq kg−1 d.w. in 2011 and 2.18 Bq kg−1 d.w. in 2013, and in roots - 7.75 Bq kg−1 d.w. and 11.44 Bq kg−1 d.w., respectively. The reduction in 90Sr concentrations in Z. marina roots to 1-2 Bq kg−1 d.w. in summer resulted from the transport of this element to the young parts of the plant. In autumn and winter, the 90Sr content in the blades of Z. marina was increasing and reached the maximum of 3.77 Bq kg−1 d.w. This could be explained by the process opposite to dilution, related to the biomass reduction and strontium concentration in the plant tissues. Changes in 90Sr concentration in Z. marina tissues are affected by isotope concentration in seawater as well as by salinity, which affects the concentration of Ca2+ - for which Sr2+ is a chemical analogue.
Solid rocks on the nearshore seabed – the distribution and potential impact on coastal processes in the Kołobrzeg region, the Southern Baltic
Authors: Rudowski Stanisław , Sitkiewicz Patryk , Wróblewski Radosław , Makurat Katarzyna
Published: March 2017

The Southern Baltic seabed is mainly composed of marine sediments situated on glacial and fluvioglacial deposits. In the Kołobrzeg region, however, solid rocks are located at the shallow subbottom. In order to determine the exact distribution of the rocks, some analyses of sonar images, underwater photos, sediment samples, seismoacoustic profiles and bathymetric data have been performed. The outcrops of Jurassic sandstones and mudstones have been documented. The geological structure of the area is presented, while the fact that the present seafloor relief is determined by the shallow uneven top surface of the Jurassic rocks is emphasized. The seabed has been classified as rock platform-constrained. The seafloor is a sediment-poor abrasion platform, within which marine sandy sediments are transported, mainly toward offshore, on the firm, stiff or hard surface of glacial deposits and Jurassic solid rocks. This results in a lack of material for the reconstruction of the beach after storms. Many of the commonly used methods for studying the condition and changes of the coast cannot be used in this type of terrain due to the presence of a thin and discontinuous dynamic layer lying on the erosion-resistant rocks of the geomorphologically complex seafloor.
Amplified fragment length polymorphism (AFLP)-based differentiation of selected Chara species
Authors: Urbaniak Jacek , Combik Michał
Published: March 2017

Charophytes are a group of green algae that grow in various types of water ecosystems and are characterized by a high degree of plasticity and morphological variation. To analyze the genetic diversity and taxonomic rank of several species from the genus Chara, the fingerprinting technique of Amplified Fragment Length Polymorphism (AFLP) was applied. We studied species that belong to sect. Grovesia (C. tenuispina, C. globularis, C. virgata, C. aspera and C. strigosa) and two species from the sect. Hartmania (C. intermedia and C. hispida). The individuals were collected in the field in north-eastern, central and eastern Poland. The species were identified based on morphological features and then analyzed using the AFLP fingerprinting method. UPGMA clustering and PCA analysis as well as morphological analysis revealed a clear separation of C. tenuispina and C. globularis, which formed separate clusters supported by high bootstrap values. Therefore, these species were distinguish as separate taxa, rather than varieties of C. globularis. Similarly, C. virgata also formed a separate cluster, thereby confirming that this taxon is a separate species, rather than a variety of C. globularis. The AFLP analysis did not show any differentiation between C. aspera and C. strigosa. The presented results do not fully support the taxonomic interpretation for the existence of several polymorphic species with numerous variations and forms, however, in some examples, the distinctive nature of the reproduction system may be used as a distinguishing feature of the taxa.

Published: March 2017

Mycological and hydrochemical research was conducted in two different types of reservoirs connected with the Narew riverbed (three tributaries and three lotic oxbow lakes) in two growing seasons. The obtained results seem to indicate that more favorable conditions for the development of the analyzed microorganisms prevailed in the studied tributaries of the Narew. A total of 36 species of fungi and fungus-like organisms were identified in these tributaries in spring and 35 in autumn, while respectively 32 and 26 species in the lotic oxbow lakes. Six taxa not identified in the oxbow lakes were found only in the tributaries of the river. They were: Alternaria alternata, Allomyces moniliformis, Catenaria anguillulae, Leptomitus lacteus, Rhipidium parthenosporum and Saprolegnia diclina. On the other hand, only two species occurred only in the oxbow lakes (not recorded in tributaries) (i.e. Catenophlyctis variabilis and Rhizophlyctis rosea).

The differences observed in the microfungi species composition in the studied ecosystems are associated, among others, with the time of the year and physicochemical properties of the water. Hydrochemical parameters such as temperature, pH, Mg, N-NH3, N-NO3, P-PO4 and suspended solids showed positive correlation, and sulfates, chlorides, Ca, Fe correlated negatively with the number of taxa observed.

Published: March 2017

Nanocrystalline nickel is an interesting material for catalysis, and also, like all nanocrystalline metals, it has potential for structural application. Our aim was to develop a method for preparation of precursor materials for powder metallurgy. Because of this, selective leaching of binary alloy was chosen as it leads to production of nanocrystalline clustered (sub)micro particles. In this work, the preparation of Ni particles by selective leaching of Al matrix from Al-50 wt.% Ni in NaOH water solution is described. It was found that structure and magnetic properties were strongly dependent on leaching temperature, which was proven by characterization of Ni particles leached at −20, 0, 20, 40, 60 and 80°C. The microstructure of as-prepared particles was observed by HRTEM and also by small angle neutron scattering. Magnetic properties were characterized by measuring of saturation magnetization. It was proven that with increased leaching temperature the grain size of prepared nanocrystalline particles increased. Also the value of saturated magnetization follows the same trend. The amount of hydrogen stored in nickel particles is independent on leaching temperature.

Published: March 2017

Extraction of Pu(IV) was investigated using solutions of two diglycolamide extractants viz., N,N,N′,N′-tetra-n-octyldiglycolamide (TODGA) and its branched homolog, N,N,N′,N′-tetra(2-ethylhexyl) diglycolamide (T2EHDGA), dissolved in two imidazolium based room temperature ionic liquids viz., 1-butyl-3-methylimidazolium bis(trifluoromethanesulphonyl) imide ([C4mim][NTf2]) and 1-octyl-3-methylimidazolium bis(trifluoromethanesulphonyl) imide ([C8mim][NTf2]) from aqueous nitric acid medium. The extraction kinetics was found to be extremely slow which is reported for the first time for analogous extraction systems and took as long as 30 h to attain equilibrium D
Pu values. In general, TODGA based solvents showed better extraction of Pu(IV) than the T2EHDGA based solvents, one order of magnitude higher, and though both the ionic liquids ultimately yielded comparable D
Pu values, attainment of equilibrium was slower with [C4mim][NTf2]. The extracted species conformed to 1:1 for TODGA in both the ionic liquids while a mixture of 1:1 and 1:2 species was observed for T2EHDGA at 1 M HNO3 which changed to 1:1 species at 4 M HNO3. The extracted species is proposed to be (Pu(L)x
4+)IL (where, L is the extractant and x=1 or 2) at lower acidities suggesting a cation exchange mechanism which changes over to (Pu(NO3)4⋅L)IL at 4 M HNO3 conforming to a solvation mechanism for all the systems except for T2EHDGA-[C8mim][NTf2]. UV-VIS spectroscopic studies were carried out to throw light on the nature of the extracted species.
Luminescence of uranyl ion complexed with 2,6-pyridine dicarboxylic acid as ligand in acetonitrile medium: observation of co-luminescence
Authors: Maji Siuli , Kumar Satendra , Sankaran Kannan
Published: March 2017

Luminescence from UO2
2+ (uranyl ion) complexed with 2,6-pyridine dicarboxylic acid (PDA) has been studied using acetonitrile (MeCN) as solvent between pH 1.0 and 6.0. The enhancement in luminescence intensity because of sensitization by PDA in the non-aqueous environment provided by the MeCN is found to be one order better than in aqueous medium. The luminescence is further enhanced by about four times following the addition of Y3+; a process known as co-luminescence. This is the first study on co-luminescence of uranyl ion in its PDA complex. Lifetime studies indicate the presence of two species having different micro-environments. Formations of both intra and inter molecular complexes are believed to be responsible for enhancement due to co-luminescence.

Authors: Feizi Shahzad
Published: March 2017

Dyed polycarbonate (PC) Radiochromic films with 20 μm thickness were prepared by casting of organic solution of PC containing 0.5 wt.% tetrakis (pentafluorophenyl) porphyrin (TPPF20) on a glass petri dish. Characterization of the film as a routine dosimeter was studied. On subjecting PC/TPPF20 film dosimeter to gamma radiation, a gradual decrease in the color of films was observed. The sensitivity of these films and the linearity of dose-response curves were studied under 60Co γ-rays expose in dose range of 0–100 kGy. The results were compared with the commercial and non-commercial dosimeters. Experimental parameters including humidity, temperature and pre-irradiation (shelf-life) and post-irradiation storage in dark and in indirect sunlight were examined. The maximum absorbance of soret band of TPPF20 had a bathochromic shift and appeared at 414 nm which remained intact in the investigated dose range. The dyed films characteristics were found to be stable enough in media with high degrees of temperature and humidity. The results indicate that radiation induced decoloration of PC/TPPF20 films can be reliably used in high dose dosimetry.

Abstract:

In clinical recommendations the normalized blood glucose level is declared as the main target in therapy of diabetes mellitus, i.e. the achievement of euglycemia is the main therapeutic goal. This approach suggests, that the normal blood glucose value is the marker of the normal carbohydrate metabolism (eumetabolism), and vice versa: hyperglycemia is associated with abnormal metabolism (dysmetabolism). However the question arises, whether identical blood glucose values do reflect the same intracellular biochemical mechanisms? On the basis of data published in the literature authors try to answer these questions by studying the relations between the short/longterm blood glucose level and the cellular metabolism in different clinical settings characterized by divergent pathophysiological parameters. The correlations between blood glucose level and cellular metabolism in development of micro-, and macroangiopathy, in the breakthrough phenomenon, as well as during administration of metabolic promoters, the discrepancies of relation between blood glucose values and cellular metabolism in type 1, and type 2 diabetes mellitus, furthermore association between blood glucose value and myocardial metabolism in acute and chronic stress were analyzed. Authors conclude, that the actual blood glucose values reveal the actual cellular metabolism in a very variable manner: neither euglycemia does mandatorily indicate eumetabolism (balance of cellular energy production), nor hyperglycemia is necessarily a marker of abnormal metabolic state (dept of cellular energy production). Moreover, at the same actual blood glucose level both the metabolic efficacy of the same organ may sharply vary, and the intracellular biochemical machinery could also be very different. In case of the very same longterm blood glucose level the metabolic state of the different organs could be very variable: some organs show an energetically balanced metabolism, while others produce a significant deficit. These inconsistencies between blood glucose level and cellular metabolism can be explained by the fact, that blood glucose value is a transport parameter, reflecting the actual steady state of glucose transport from the carbohydrate pools into the blood, and that from the blood into the tissues. Without knowing the speed of these transports of opposite direction, the blood glucose value per se can not reveal the quantitative and qualitative characteristics of cellular metabolism. Orv.

Basil (Ocimum sp.), generally knowned as 'king of herbs' due to its pharmaceutical and culinary properties, is considered to be a native plant derived from Africa and Asia. Ocimum sp. grows in tropical and sub-tropical regions with more than 50 species knowned till present time. Germination percent of Ocimum sp. is considered to be between 85-95%. Even though Ocimum sp. are considered to have fast germination velocity index (GVI), short mean germination time (MGT) and increased seedling vigor index (SVI) values, their experimental monitoring is done with specialized software's that are expensive. Low cost scientific solutions are keen on open source software germination protocols. For observing the accuracy of open source C.A.D. software's Ocimum sp. seeds where submitted to high frequency pulsatile electromagnetic fields (300 impulses/3 peak penetrance - 293 W) and ultrasound pulsatile fields (1/2 pulses by 0.5 W/cm2). All sequence images where taken using a positive/negative photo filter enhancing differences in seed development. At the end of the experiment all images where transformed into vector formats (dwg). On the dwg extension, selective free plug-ins such as Face Centroid and Area Properties help to collect data like seed development on X/Y scale, area, perimeter, no. of germinated seeds, length of seedling root, hypocotyl length.

Published: March 2017

In flowering plants, gametophytic self-incompatibility, controlled by a single locus with several allelic variants, is one of the major problems preventing self-fertilization. Among fruit trees, apricots show to a high degree self-incompatibility, especially in Middle-Asian and Iranian-Caucasian eco-geographical groups. In the present study, self-(in)compatibility characteristics of a total of 236 apricot genotypes (218 Turkish and 18 foreign) found within the National Apricot Germplasms of Apricot Research Institute in Malatya, Turkey was studied. Analyses were carried out by using four primer pairs (SRc-F and SRc-R, EM-PC2consFD and EM-PC3consRD, AprSC8-R and PaConsI-F, AprFBC8-F and AprFBC8-R). A total of 11 S-RNase alleles (S2, S3, S6, S7, S8, S9, S11, S12, S13, S20 and Sc) were determined in the 236 apricot genotypes. As Turkish and foreign apricot genotypes are determined mostly self-incompatible, the data obtained hereby might be of good use for apricot breeding programs and more practically, for apricot new plantations; thus pollinator cultivars should be considered when self-incompatible apricot cultivars are being used.

The purpose of this study was to assess the most frequent non-conformities identified in different European countries in the processes of forest management certification according to FSC standards. A total of 31 active certificates from five countries (Bosnia and Herzegovina, Estonia, Romania, Slovenia and the United Kingdom) were analysed, including all active certificates (as of 1st of June 2014) from three countries along with a sample of 13 FSC certificates issued in the UK and one certificate covering 95% of the certified forest area in Slovenia. 253 non-conformities in relation to FSC standard requirements were identified as formulated by the audit teams and the most frequently identified non-conformities in the certification process were those related to Principle 6 - Environmental impact (34%), Principle 4 - Community relations and workerâ€™s rights (17%) and Principle 8 - Monitoring and Assessment (13%). A slight positive correlation was noticed between the FSC certified area and the total number of non-conformities, with a closer link in the case of Principle 9 - Maintenance of high conservation value forests, and Principle 4. The non-conformities related to Principles 4, 6 and 9 appeared to be significantly influenced in occurrence by country development; less often in the UK compared with the other four countries.
Photosynthetic and Growth Responses of Olive to Proline and Salicylic Acid under Salinity Condition
Authors: ALINIAEIFARD Sasan , HAJILOU Jafar , TABATABAEI Seyed Jalal
Published: March 2017

Salinity has a negative impact on growth and productivity of crops on agricultural lands. Since proline and salicylic acid are used by plants to cope with stress conditions, to test whether they can help olive plants to alleviate negative impacts of salt stress, an experiment was carried out by spraying proline (15 mM) and salicylic acid (0.25 mM) on the plants that subjected to two salinity levels (0 and 100 mM NaCl). Salinity caused an alteration in biomass partitioning; in such a way that shoot vegetative growth was more restricted by salinity than root vegetative growth. Root volume was increased in proline-sprayed plants while salinity caused a decline in the root volume. Salinity resulted in an increase in specific leaf area. Net photosynthesis, stomatal conductance and transpiration rate were decreased by salinity application in root medium. Peroxidase activity decreased in plants that subjected to salinity stress. However, application of proline resulted in improvement of vegetative growth in both control and salinity conditions. Increase in chlorophyll index was observed following proline application, while salinity caused a decline in chlorophyll index. In conclusion, salinity can cause deleterious effects on photosynthesis and vegetative growth of olive trees. Exogenous application of proline can help plants to cope with negative effects of salt stress on olive plants.

Olive and olive oil have a prominent place in the cultures of the countries within the Mediterranean basin including Turkey. The genetic relationships among 30 olive (Olea europaea L.) genotypes sampled from Gaziantep province in Turkey were examined using 10 simple sequence repeat (SSR) markers (DCA9, DCA11, DCA15, DCA18UDO4, UDO9, UDO11, UDO12, UDO22, UDO24). Also, three well known Turkish and one foreign olive cultivar were also included within the SSR analysis. The number of alleles per locus of the SSR markers ranged from 5 (DCA15, UDO9) to 14 (DCA9) (average 7.9), for a total of 79 alleles. Similarity coefficients were calculated on the basis of 79 amplified bands. A dendrogram was created according to the 10 SSR markers by the unweighted pair-group method. The banding patterns obtained from the SSR primers allowed all of the genotypes/cultivars to be distinguished. According to the dendrogram, the 33 olive genotypes and cultivars were clustered into five main clusters. The most closely related genotypes were 'Oguzeli 3' and 'Yavuzeli 1' with 0.80 similarity ratio. The most genetically divergent cultivars were 'Yavuzeli 6' and 'Kilis Yaglik' (0.30), 'Yavuzeli 6' and 'Saurani' (0.20), 'Nizip 7' and 'Yavuzeli 4' (0.15), 'Islahiye 5' and 'Nizip Yaglik' (0.10). In conclusion, SSR analysis can be an efficient method for olive genotypes and cultivar identification and can offer valuable informative data to identify olive genotypes and cultivars grown in Turkey.
Modernização do Estado e construção de capacidade burocrática para a implementação de políticas federalizadas
Authors: Souza Celina
Published: March 2017

Resumo O artigo analisa o processo de modernização do Estado brasileiro associando-o ao conceito de capacidade do Estado, em especial, a profissionalização da burocracia federal que atua na formulação e implementação de políticas públicas. O artigo conclui que, a despeito da ocorrência de múltiplos mecanismos utilizados pelos diferentes governos e regimes políticos para o recrutamento da sua burocracia, o Executivo federal sempre foi capaz de gerar capacidade para implementar suas políticas preferenciais. Nas duas últimas décadas, contudo, o Executivo federal passou a recrutar sua burocracia majoritariamente por meio de concursos públicos, havendo hoje uma burocracia consolidada atuando no controle de regras e procedimentos e no controle fiscal, mas ainda incompleta em algumas áreas de políticas públicas. Essas novas características do sistema burocrático federal indicam que algumas das dimensões de uma burocracia weberiana foram construídas enquanto outras aguardam institucionalização, afetando, portanto, a capacidade do Estado em determinadas políticas.

Authors: Bonifácio Robert , Ribeiro Ednaldo
Published: March 2017

Resumo Investiga-se a relação entre corrupção e participação política no Brasil, a partir de análises sobre padrões de associação pertinentes e sobre a permissividade à corrupção de perfis sociais que combinam categorias de experiência com corrupção e de ativismo político. São realizadas discussões teóricas e análises empíricas, tendo como fonte exclusiva de dados o Barômetro das Américas, rodadas de dados de 2007, 2008, 2010 e de 2012. Como principais resultados, verifica-se a natureza multidimensional da participação política, segmentada em quatro modalidades distintas. Também é destaque a inequívoca associação positiva entre experiência com corrupção e engajamento político. Por fim, identifica-se uma maior permissividade à corrupção (tolerância ao pagamento de propina) entre os indivíduos que possuem experiência com corrupção, independentemente dessa característica estar ou não acompanhada de ativismo político.

Abstract This study aimed to assess the impact of oral health on the quality of life of adolescents. A cross-sectional study was performed with students from public and private schools from Passo Fundo, Brazil. All students were aged between 15 and 19 years old. The proportional random sample consisted of 736 adolescents from 20 schools. A structured questionnaire was applied, and an oral examination was performed, counting the number of teeth. Oral health-related quality of life was assessed by OHIP-14. Associations between quality of life and associated factors were analyzed. The mean OHIP-14 score was 7.25. Age, ethnicity and studying in a public school were associated to the OHIP-14 score. Tooth loss (p=0.79) was not associated with quality of life. Additionally, questions related to appearance, such as whether teeth appearance bothers the adolescent (p=0.68) were not associated with quality of life. Attending a public school (OR=1.63; CI95%: 0.98-2.70) and self-reported halitosis (OR=1.48; CI95%: 1.01-2.16) were strongly associated to higher impact on quality of life. It was concluded that socioeconomic conditions and halitosis were associated to higher impact on quality of life of adolescents

Abstract There are few informations about the influence of cusp inclination on the fracture strength of implant-supported crowns. The study aimed to evaluate the influence of cusp inclination and retention type on fracture load in implant-supported metal-ceramic single crowns. Sixty crowns were made, classified as cemented and screw-retained with screw access hole (SAH) sealed or not. Standard (33°) and reduced (20°) cusp inclinations were tested for each group (n=10). To support crowns of a mandibular second molar, analogs of external hexagon implants 5.0 were used. The fracture load was measured in a universal testing machine EMIC DL2000 (10 kN load cell; 0.5 mm/min). Two-way ANOVA (retention and cusp inclination) followed by post hoc Tukey’s honest significant difference test was used for the statistical analyses (a=0.05). Crowns with reduced cusp inclination exhibited significantly higher fracture load (p<0.01) than crowns with standard cusp inclination. Cemented crowns showed significantly higher fracture load (p<0.01) than screw-retained crowns. The interaction among these factors was not significant (p>0.05) for the fracture load. The sealing of SAH did not influence the fracture load of screw-retained crowns (p>0.05). In conclusion, fracture load of implant-supported metal-ceramic crowns was influenced by retention and cusp inclination, and there was no influence of the sealing of SAH.
Os municípios brasileiros e os gastos próprios com saúde: algumas associações
Authors: Araújo Carmem Emmanuely Leitão , Gonçalves Guilherme Quaresma , Machado José Angelo
Published: March 2017

Resumo Em um contexto que combina descentralização e subfinanciamento da política pública de saúde, os municípios brasileiros ampliam de modo expressivo seus gastos no setor, alocando proporção das receitas próprias (tributação direta somada às transferências intergovernamentais obrigatórias da União e dos estados) em níveis superiores aos determinados constitucionalmente. Porém, ainda são incipientes os estudos que investigam a composição das despesas com saúde nessas unidades federativas, de modo a descrever suas principais características e explicações. A fim de contribuir para a supressão desta lacuna, o presente artigo explora algumas associações entre atributos dos municípios (porte populacional, região do país, proporção de idosos, mortalidade infantil, contratação de serviços privados e transferência SUS) e despesas em saúde executadas com receitas próprias. O estudo realizou estatísticas descritivas e regressões lineares múltiplas para investigar tais associações com dados referentes ao ano de 2010. Os resultados sinalizam para iniquidades fiscais no setor ao se comparar municípios de diferentes faixas populacionais e condições socioeconômicas, entre os quais, são percebidas importantes diferenças em termos dos gastos per capita com os elementos de despesa analisados.

Resumo A contratualização consiste no desenvolvimento e implementação de um acordo documentado, através do qual uma das partes (financiador) prevê uma compensação à outra parte (prestador), em troca de um conjunto de serviços de saúde a uma população-alvo. Descrevemos, mediante um estudo de caso, a história e o processo de implementação da contratualização nos cuidados de saúde primários portugueses (desde 1992), dando-se ênfase à consolidação da reforma dos cuidados de saúde primários, iniciada em 2005 e apontando desafios de futuro. Este artigo recorre ao estudo de caso, para refletir sobre os resultados obtidos no Agrupamento de Centros de Saúde do Oeste Norte, da Administração Regional de Lisboa e Vale do Tejo, entre 2009 e 2015, depois de terem implementado a contratualização. Verificou-se que o pagamento por incentivos terá de ser ponderada, em vista dos resultados obtidos, fortemente influenciados pelas mudanças epidemiológicas e socioeconômicas.

ABSTRACT Objective: to analyze managers and professionals' perceptions on the changes in hospital management deriving from accreditation. Method: descriptive study with qualitative approach. The participants were five hospital quality managers and 91 other professionals from a wide range of professional categories, hierarchical levels and activity areas at four hospitals in the South of Brazil certified at different levels in the Brazilian accreditation system. They answered the question "Tell me about the management of this hospital before and after the Accreditation". The data were recorded, fully transcribed and transported to the software ATLAS.ti, version 7.1 for access and management. Then, thematic content analysis was applied within the reference framework of Avedis Donabedian's Evaluation in Health. Results: one large family was apprehended, called "Management Changes Resulting from the Accreditation: perspectives of managers and professionals" and five codes, related to the management changes in the operational, structural, financial and cost; top hospital management and quality management domains. Conclusion: the management changes in the hospital organizations resulting from the Accreditation were broad, multifaceted and in line with the improvements of the service quality.
Distribution and abundance of freshwater decapods in an Atlantic rainforest catchment with a dammed future

Published: March 2017

Abstract Variations in physical characteristics along the course of a river influence habitat availability which reflects in species distribution. Knowledge of ecology and diversity of lotic species is important for evaluating how river ecosystems will respond to environmental impacts. Freshwater decapods are a group of high ecological and economic importance, but the knowledge about factors influencing their distribution is scarce in Brazil. We performed a survey of decapods to describe their abundance and distribution as well as to study their relationships with stream physical variables and especially their association with different substrates types. We studied 23 sites located in 15 tributaries of Guapiaçú River, RJ, where we collected decapods in different substrates types and measured a set of physical variables. We found five decapods species, including amphidromous and non-amphidromous shrimps and crabs. Decapods were strongly associated with leaf-litter substrates and their abundance was related to a multivariate axis describing longitudinal changes in stream characteristics. We concluded that decapods occurring in the Guapiaçú catchment inhabit mainly small streams with preserved riparian forests where they find shelter and potential prey of invertebrates. The ongoing project to build a dam on the Guapiaçú River will have negative consequences to migrating shrimps and we strongly recommend that mitigating actions, such the construction of structures to allow the passage of migrating fauna, should be taken.
