The study of the chemical composition of chlorites from the Santa Rosa and Lutitas de Macanal formations in the eastern emerald belt (eastern cordillera), are used to estimate the formation temperature of these minerals and the associated hydrothermal fluids. The chlorites were analyzed using the classification proposed by hey (1954), foster (1962), and Bailey (1980); and the formation temperature is calculated from empirical geothermometers from kranidiotis and Maclean (1987), Cathelineau (1988), Jowett (1991) and Xie et al. (1997). Chlorites in hydrothermally altered rocks associated with emerald mineralization of the Santa Rosa formation is classified as clinochlore and formed at temperatures of 354 Celsius degrade; this temperature is consistent with the fluid inclusions in emeralds of the same formation. Chlorites in veins from Lutitas de Macanal Formation are classified as chamosites and formed at lower temperatures between 210 to 225 Celsius degrade

In 1987 the Regional Autonomous Corporation of Risaralda, CARDER and the Risaralda Government, they signed a cooperation agreement, in order to endowing from sanitary landfill to the municipalities of the department. In the mark of this agreement it was carried out the design of Santa Rosa's sanitary landfill, that with near 50.000 inhabitants it is constituted in the third city of the department. This city generates some 25 tons/day of garbage that at the present time are heady directly to the waters of San Eugenio River. The present work contains the most important methodological aspects in the design of the sanitary landfill and some comments about the approaches ideal Vs real approaches of selection of places

Schumann et al. (2016) presented a field assessment of late Pleistocene to Holocene fluvial sediments preserved in the valleys of Santa Rosa Island, California. This is a rigorous study, based on stratigraphic descriptions of 54 sections and numerous radiocarbon ages. The paper makes important contributions that we would like to highlight, but other parts of the paper rely upon overly simplistic interpretations that lead to misleading conclusions. In one case, a conclusion of the Schumann et al. paper has important management implications for Santa Rosa Island and similar locations, compelling us to discuss and qualify this conclusion.

Association between mapped vegetation and Quaternary geology on Santa Rosa Island, California

Vegetation and surficial geology are closely connected through the interface generally referred to as the critical zone. Not only do they influence each other, but they also provide clues into the effects of climate, topography, and hydrology on the earth's surface. This presentation describes quantitative analyses of the association between the recently compiled, independently generated vegetation and geologic map units on Santa Rosa Island, part of the Channel Islands National Park in Southern California. Santa Rosa Island was heavily grazed by sheep and cattle ranching for over one hundred years prior to its acquisition by the National Park Service. During this period, the island experienced significant erosion and spatial reduction and diversity of native plant species. Understanding the relationship between geology and vegetation is necessary for monitoring the recovery of native plant species, enhancing the viability of restoration sites, and understanding hydrologic conditions favorable for plant growth. Differences in grain size distribution and soil depth between geologic units support different plant communities through their influence on soil moisture, while differences in unit age reflect different degrees of pedogenic maturity. We find that unsupervised machine learning methods provide more informative insight into vegetation-geology associations than traditional measures such as Cramer's V and Goodman and Kruskal's lambda. Correspondence analysis shows that unique vegetation-geology patterns associated with beach/dune, grassland, hillslope/colluvial, and fluvial/wetland environments can be discerned from the data. By combining geology and vegetation with topographic variables, mixture models can be used to partition the landscape into multiple representative types, which then be compared with conceptual models of plant growth and succession over different landforms. Using this collection of methods, we show various ways that that Quaternary geology

Costa Rica like rest of the world, erosion has negative effects on agricultural production systems and hydroelectric power. In a country where 95% of energy is produced by hydroelectric plants, the management of watersheds is essential where there are hydro projects. This study evaluates the potential erosion of the watershed of the Rio Santa Rosa, (10445 ha) in Guanacaste, Costa Rica, which supplies sediment to the Santa Rosa and Sandillal dams. The evaluation places were defined using aerial photography GIS and GPS tools. The sediment was measured through 19 experimental plots in two land uses (pasture and forest) and three slope ranges (0-15%, 15-30%, 30-45%). The energy was determined on erosive rains comparing the mass of sediment collected. The most vulnerable areas were identified, to define appropriate mitigation measures. It was found that the forest generates more erosion than grass. Furthermore, under similar conditions of coverage, an increase in the range of slopes, erosion increases between two and six times, a direct relationship exists between energy and erosion in the way that coverage is reduced. It was generated a vulnerability map for the watershed. (author)

Se encontró una alta diversidad edáfica a escalas pequeñas (0.5-1 ha y se describieron 17 clases dominantes de suelos, clasificados en seis órdenes. La mayoría de los suelos fueron clasificados como Entisoles y Vertisoles, pero los Mollisoles, Alfisoles, Inceptisoles y Ultisoles estuvieron representados también. Todos los suelos presentaron buenos índices de fertilidad que no restringieron la riqueza de las especies. La alta heterogeneidad edáfica pareció ser el resultado de la interacción entre el origen piroclástico de la meseta ignimbrítica de Santa Rosa, la composición litológica y la acidez de las rocas del material parental, la marcada estacionalidad de la lluvia, intensos procesos de erosión hídrica y eólica, variaciones topográficas locales, y la historia de intervención humana.

The long-term history of vegetation and fire was investigated at two locations – Soledad Pond (275 m; from ca. 12 000 cal. a BP) and Abalone Rocks Marsh (0 m; from ca. 7000 cal. a BP) – on Santa Rosa Island, situated off the coast of southern California. A coastal conifer forest covered highlands of Santa Rosa during the last glacial, but by ca. 11 800 cal. a BP Pinus stands, coastal sage scrub and grassland replaced the forest as the climate warmed. The early Holocene became increasingly drier, particularly after ca. 9150 cal. a BP, as the pond dried frequently, and coastal sage scrub covered the nearby hillslopes. By ca. 6900 cal. a BP grasslands recovered at both sites. Pollen of wetland plants became prominent at Soledad Pond after ca. 4500 cal. a BP, and at Abalone Rocks Marsh after ca. 3465 cal. a BP. Diatoms suggest freshening of the Abalone Rocks Marsh somewhat later, probably by additional runoff from the highlands. Introduction of non-native species by ranchers occurred subsequent to AD 1850. Charcoal influx is high early in the record, but declines during the early Holocene when minimal biomass suggests extended drought. A general increase occurs after ca. 7000 cal. a BP, and especially after ca. 4500 cal. a BP. The Holocene pattern closely resembles population levels constructed from the archaeological record, and suggests a potential influence by humans on the fire regime of the islands, particularly during the late Holocene.

History of a modern place: Clorindo Testa and the Santa Rosa Civic Center, La Pampa

Full Text Available Santa Rosa, capital of the young province of La Pampa, was founded in 1892 at the end of the military campaigns that annihilated the indigenous people and ensured republican control over the Patagonia region. In 1955, the city held a design competition for the construction of its Civic Center. This was not a current infill operation intended to renew the core of the city, since it was not just a matter of raising a new facade along one of the four sides of the main square. The task implied designing, almost from scratch, a new part of city. Competitors were supposed to organize new buildings and public spaces within an area of nine hectares standing between the existing city and the surrounding pampas. Clorindo Testa won the competition by proposing that it be built as a piece of a modern city. Situated in the middle of Argentinean pampas, the Santa Rosa Civic Center has been less extensively discussed than other of Testa’s great contemporary works, such as the London Bank (1959 and the National Library (1962, both in Buenos Aires, even in the South American context. The Government Building, the Bus Station and the covered central space were built before 1963. Testa finished the Legislature Building in 1976, and even though in 2006 he was able to conclude the little Legislature Library, half of the Civic Center area still remains as open space. Nevertheless, as a living piece of the never-completed modern project installed in the far south, La Pampa’s case seems to pose relevant urban questions. This paper explores the case from two complementary perspectives. One focuses on the results of the first competition, recognizing an original contribution to the relationship between modernity, monument, and place. The second discusses the unfinished condition of the Civic Center as constitutive to modern tradition in the very modern sense of the city as a never-completed work.

Curtis, Jennifer A.; Flint, Lorraine E.; Hupp, Cliff R.

2013-01-01

We present a conceptual and analytical framework for predicting the spatial distribution of floodplain sedimentation for the Laguna de Santa Rosa, Sonoma County, CA. We assess the role of the floodplain as a sink for fine-grained sediment and investigate concerns regarding the potential loss of flood storage capacity due to historic sedimentation. We characterized the spatial distribution of sedimentation during a post-flood survey and developed a spatially distributed sediment deposition potential map that highlights zones of floodplain sedimentation. The sediment deposition potential map, built using raster files that describe the spatial distribution of relevant hydrologic and landscape variables, was calibrated using 2 years of measured overbank sedimentation data and verified using longer-term rates determined using dendrochronology. The calibrated floodplain deposition potential relation was used to estimate an average annual floodplain sedimentation rate (3.6 mm/year) for the ~11 km2 floodplain. This study documents the development of a conceptual model of overbank sedimentation, describes a methodology to estimate the potential for various parts of a floodplain complex to accumulate sediment over time, and provides estimates of short and long-term overbank sedimentation rates that can be used for ecosystem management and prioritization of restoration activities.

Full Text Available Ecuador is immersed, since the adoption of the 2008 Constitution, in a process of economic, social and political changes, following the steps on their path to a more equal, post-extractive and democratic society. The main tool for this purpose, the National Strategy for the «Buen Vivir» (Good living and the Change in the Production Model emphasizes new ways for producing, consumption and self-organization. Although Ecuadorian Constitution comprises these ideas and the Ecuadorian Government has promoted different programs and strategies, there is a limited analysis about the local manifestations of these policies. In this way, this paper proposes a study of the local strategies developed in a medium-size city in the south of Ecuador through the analysis of the local networks and the initiatives of local actors for developing strategies oriented to this end. Interviews and statistical data (demographic, economic and social data mainly are used to confirm the level of accomplishment of these objectives. Thus, the existing local networks and the path of the city of Santa Rosa may explain the different level of recent socioeconomic changes taken place at local level instead of Central government policies.

Se argumenta que la historia de la región, en específico el auge de la industria minera durante la Colonia, es un buen punto de partida para entender los problemas ambientales de la sierra y para visualizar el vínculo entre las estructuras que funcionan en detrimento del medio ambiente y de las mujeres. Así como también que dicho programa tuvo un efecto positivo en la participación social de las mujeres. Sin embargo, existen todavía retos importantes que se manifiestan en estructuras ideológicas, que impiden la participación de las mujeres como líderes y no sólo como trabajadoras, en las condiciones de pobreza que obstaculizan un verdadero compromiso con la sustentabilidad.

Two-Phase Exhumation of the Santa Rosa Mountains: Low- and High-Angle Normal Faulting During Initiation and Evolution of the Southern San Andreas Fault System

Mason, Cody C.; Spotila, James A.; Axen, Gary; Dorsey, Rebecca J.; Luther, Amy; Stockli, Daniel F.

2017-12-01

Low-angle detachment fault systems are important elements of oblique-divergent plate boundaries, yet the role detachment faulting plays in the development of such boundaries is poorly understood. The West Salton Detachment Fault (WSDF) is a major low-angle normal fault that formed coeval with localization of the Pacific-North America plate boundary in the northern Salton Trough, CA. Apatite U-Th/He thermochronometry (AHe; n = 29 samples) and thermal history modeling of samples from the Santa Rosa Mountains (SRM) reveal that initial exhumation along the WSDF began at circa 8 Ma, exhuming footwall material from depths of >2 to 3 km. An uplifted fossil (Miocene) helium partial retention zone is present in the eastern SRM, while a deeper crustal section has been exhumed along the Pleistocene high-angle Santa Rosa Fault (SFR) to much higher elevations in the southwest SRM. Detachment-related vertical exhumation rates in the SRM were 0.15-0.36 km/Myr, with maximum fault slip rates of 1.2-3.0 km/Myr. Miocene AHe isochrons across the SRM are consistent with northeast crustal tilting of the SRM block and suggest that the post-WSDF vertical exhumation rate along the SRF was 1.3 km/Myr. The timing of extension initiation in the Salton Trough suggests that clockwise rotation of relative plate motions that began at 8 Ma is associated with initiation of the southern San Andreas system. Pleistocene regional tectonic reorganization was contemporaneous with an abrupt transition from low- to high-angle faulting and indicates that local fault geometry may at times exert a fundamental control on rock uplift rates along strike-slip fault systems.

The best performing areas are animal welfare (81% and those related to the milking routine (79.1%; On the other hand, the most deficient were the control of veterinary drugs and agricultural products (5.8%, as well as the conditions of the cooling tank (32.6%. Through a Multiple Correspondence Analysis, a significant association was found between variables involved with the guarantee in the safety of the milk, regarding the operation, cleaning and disinfection of equipment that guarantee an adequate temperature. There was also an association between variables involved in the milking procedure and hygienic conditions during the milking procedure, involving both the operator and the animal. A lack of training and awareness about the importance of compliance with many of these criteria was found, this is a fundamental tool to obtain a diagnosis of the current sanitary status, and in which it may be necessary to take into account other variables, not included in the current checklist, for a later implementation and follow-up to improvement plans of the productive systems.

Full Text Available Tardigrade diversity was studied in a medium-sized city in the Neotropical Region: Santa Rosa (La Pampa, Argentina. Samples were collected between February 1999 and January 2000 from lichens and mosses growing on sidewalk trees of the urban and periurban area. Five species of tardigrades were found, i.e., Echiniscus rufoviridis du Bois-Reymond Marcus, 1944, Macrobiotus areolatus Murray, 1907, Ramazzottius oberhaeuseri (Doyère, 1840, Milnesium cf. tardigradum and a non-described species of Macrobiotus. Only one species, M. cf. tardigradum, was found in areas with high levels of vehicle traffic. Results are compared with those from cities in the Nearctic and Palearctic regions. Measurements and pt index values (percentage ratios between the length of the structure considered and the buccal tube length are provided for M. areolatus, R. oberhaeuseri and M. cf. tardigradum. Amongst the characters considered, the pt index for the stylet support insertion shows the least intraspecific variation. This character is also independent from body length and buccal-tube length.

Full Text Available Salvator Rosa (Napoli, 1615- Roma 1673 fu pittore e poeta tra i più interessanti del secolo diciassettesimo. Il saggio intende indagare il complesso rapporto artistico e personale che Rosa ebbe con la città di Napoli, in cui era nato e dalla quale era quasi fuggito quando era poco più che un ragazzo. Attraverso una lettura delle principali fonti biobibliografiche a lui contemporanee, di alcune delle sue tele, dei versi delle Satire e di stralci delle lettere che a Napoli dedicherà, s’intende sottolineare che della capitale del Meridione la scrittura e l’arte di Salvator Rosa sono in grado di restituirci un’immagine altra rispetto a quella topica di Napoli gentile, perla luminosa di quella Campania felix che proprio nel Seicento attrae pittori e poeti da ogni parte d’Europa. Nei versi di Rosa, come nella scrittura in prosa, Napoli è, infatti, croce e delizia, prigione da cui fuggire e porto di quell’agognato ritorno che, al di là delle leggendarie asserzioni di alcuni biografi romantici, mai avverrà.   Salvator Rosa (Naples, 1615- Rome, 1673 was a painter and poet among the most interesting of the seventeenth century.

Through a reading of the main biobibliographic sources to him contemporary, some of his canvases, the verses of the Satire and the excerpts of the letters that Naples will dedicate, it is meant to point out that in the capital of the South the writing and art of Salvator Rosa are Able to give us an image other than the topical one of Napoli's kind, bright pearl of the Campania felix that in the seventeenth century attracts painters and poets from all over Europe. In the lines of Rosa, as in prose writing, Naples is, in fact, a cross and delight, a prison from which to flee and bring about that auspicious return that

Full Text Available Rosa Luxemburgo was a complete revolutionary in her theoretical production and action. An internationalist, she was a communist in action and in participatory thinking, who was dedicated to defending working class interests, with a constant concerned for liberty, democracy, complete development and for fighting bureaucracy. She was distinguished for not accepting traditional formulas, while remaining very rigorous with herself, never ceasing to reformulate her ideas and actions, which in her understanding, had a special value in a liberating political struggle. Today, the ?battle of ideas? acquires a very important place in Latin America and the Caribbean, as basic support in the articulation of the social and political realms, and the construction of a future of emancipation, of which Rosa Luxemburgo was a pioneer.

Mapping process and age of Quaternary deposits on Santa Rosa Island, Channel Islands National Park, California

Schmidt, K. M.; Minor, S. A.; Bedford, D.

2016-12-01

Employing a geomorphic process-age classification scheme, we mapped the Quaternary surficial geology of Santa Rosa (SRI) within the Channel Islands National Park. This detailed (1:12,000 scale) map represents upland erosional transport processes and alluvial, fluvial, eolian, beach, marine terrace, mass wasting, and mixed depositional processes. Mapping was motivated through an agreement with the National Park Service and is intended to aid natural resource assessments, including post-grazing disturbance recovery and identification of mass wasting and tectonic hazards. We obtained numerous detailed geologic field observations, fossils for faunal identification as age control, and materials for numeric dating. This GPS-located field information provides ground truth for delineating map units and faults using GIS-based datasets- high-resolution (sub-meter) aerial imagery, LiDAR-based DEMs and derivative raster products. Mapped geologic units denote surface processes and Quaternary faults constrain deformation kinematics and rates, which inform models of landscape change. Significant findings include: 1) Flights of older Pleistocene (>120 ka) and possibly Pliocene marine terraces were identified beneath younger alluvial and eolian deposits at elevations as much as 275 m above modern sea level. Such elevated terraces suggest that SRI was a smaller, more submerged island in the late Neogene and (or) early Pleistocene prior to tectonic uplift. 2) Structural and geomorphic observations made along the potentially seismogenic SRI fault indicate a protracted slip history during the late Neogene and Quaternary involving early normal slip, later strike slip, and recent reverse slip. These changes in slip mode explain a marked contrast in island physiography across the fault. 3) Many of the steeper slopes are dramatically stripped of regolith, with exposed bedrock and deeply incised gullies, presumably due effects related to past grazing practices. 4) Surface water presence is

Geochronology and Geochemistry of a Late Cretaceous Granitoid Suite, Santa Rosa Range, Nevada: Linking Arc Magmatism in Northwestern Nevada to the Sierra Nevada Batholith

Science.gov (United States)

Brown, K.; Stuck, R.; Hart, W. K.

2010-12-01

Throughout the Mesozoic, an arc-trench system dominated the western margin of North America. One of the principal records of this system’s evolution is a discontinuous alignment of deeply eroded batholiths, which represent the once-active roots of ancient volcanic systems. Although these batholiths extend from Alaska to Mexico, there is a prominent (~500 km) gap located in present-day Nevada that contains scattered plutons that are hypothesized to be similar in age and origin to the larger batholiths. The current understanding of these isolated plutons, however, remains limited to regional isotopic studies aimed at identifying major crustal boundaries and structural studies focused on emplacement mechanisms. Therefore, detailed petrogenetic studies of the plutons exposed within the Santa Rosa Range (SRR) of NW Nevada will better characterize magmatism in this region, placing them within a regional context that explores the hypothesized links between the intrusions of NW Nevada to the Sierra Nevada batholith (SNB). A compilation of published geochronology from this region shows that plutons in the SRR are broadly coeval with the Cathedral Range Intrusive Epoch (~95-83 Ma) and the Shaver Sequence (~118-105 Ma) of the SNB. Preliminary Rb-Sr geochronology from the Granite Peak stock reveals a previously unrecognized period of magmatism (ca. 85.0 Ma) in this region. Therefore, ongoing work will more completely characterize the timing of magmatic pulses in this region and their relationships to the SNB. Preliminary petrographic, geochemical, and isotopic observations suggest that two distinct compositional/textural groups exist: the Santa Rosa/ Andorno group (SRA) and Granite Peak/ Sawtooth group (GPS). The chemical and isotopic variations between the two groups suggest that they were not consanguineous. Whereas the SRA group is generally more mafic (64-72 wt% SiO2) and metaluminous, the GPS group is more felsic (72- 76 wt% SiO2) and peraluminous. This observation is

The latest developments of the ROSA (Reloading Optimization by Simulated Annealing) code system with an emphasis on the first full-core version and the minimum DNBR (Departure from Nucleate Boiling Ratio) as a new optimization parameter are presented. Designing the core loading pattern of nuclear power plants is becoming a more and more complex task. This task becomes even more complicated if asymmetries in the core loading pattern arise, for instance due to damaged fuel assemblies. For over almost 2 decades ROSA, NRG's (Nuclear Research and consultancy Group) loading pattern optimization code system for PWRs, has proven to be a valuable tool to reactor operators in accomplishing this task. To improve the use of ROSA for designing asymmetric loading patterns, NRG has developed a full-core version of ROSA besides the original quarter-core version which requires rotational symmetry in the computational domain. The extension of ROSA with DNBR as an optimization parameter is part of ROSA's continuous development. (orig.)

Economic optimization of PWR cores with ROSA

International Nuclear Information System (INIS)

Verhagen, F.C.M.; Wakker, P.H.

2005-01-01

The core-loading pattern is decisive for fuel cycle economics, fuel safety parameters and economic planning for future cycles. ROSA, NRG's loading pattern optimization code system for PWRs, has proven for over a decade to be a valuable tool to reactor operators for improving their fuel management economics. ROSA uses simulated annealing as loading pattern optimization technique, in combination with an extremely fast 3-D neutronics code for loading pattern calculations. The code is continuously extended with new optimization parameters and rules. This paper outlines recent developments of the ROSA code system and discusses results of PWR specific applications of ROSA. Core designs with a large variety of challenging constraints have been realized with ROSA. As a typical example, for the 193 assembly, Vantage 5H/RFA-2 fueled TVA's Watts Bar unit 1, a cycle 4 core with 76 feed assemblies was designed. This was followed by a high-energy cycle 5 with only 77 feed assemblies and approximately 535 days of natural cycle length. Subsequently, an economical core using 72 bundles was designed for cycle 6. This resulted in considerable savings in the cost of feed assemblies for reloads. The typical accuracy of ROSA compared to results of license codes in within ±0.02 for normalized assembly powers, ±0.03 for maximum enthalpy rise hot channel factor (F ΔH ), and ±3 days for natural cycle length.

Soda, Kunihisa

1978-06-01

ROSA-III experiment with the simulated BWR system is to investigate thermal hydraulic behavior as well as ECCS performance in a postulated loss-of-coolant accident. RUN 701 assumes average core power, high and low pressure core sprays and low pressure injection of ECCS. Prediction of experiment RUN 701 was made with computer code RELAP-4J. The results indicate the need for ROSA-III pump characteristics to be clarified and for liquid level formation model to be improved. Comparison of the prediction results with the experimental data should reveal the areas of modifications in calculation model. (auth.)

Para determinar a sensibilidade da flor ao etileno, hastes foram cortadas e colocadas em câmaras herméticas e em seguida tratadas por 24 horas com diferentes concentrações de etileno variando de 0,0; 0,1; 1,0; 10; 100 e 1000 µL L-1do ar no interior da câmara. A rosa teve a vida pós-colheita reduzida pelo etileno, quando exposta a concentração igual ou superior a 10 µL L-1 de etileno. As flores tratadas com no mínimo de 10 µL L-1de etileno desenvolveram necrose, murcha e abscisão prematura das pétalas ainda túrgidas. As concentrações de 0,1 e 1,0 µL L-1de etileno estimularam a abertura do botão floral durante o período de 24 horas de exposição ao etileno, sem no entanto, reduzir a vida pós-colheita. A rosa 'Osiana' pode ser classificada como uma cultivar sensível ao etileno e a concentração influência os processos estimulados.

2005-01-01

Mutation induction is an alternative method to create more variation in Hibiscus rosa-sinensis. Radiosensitivity test was carried out to determine the effective doses for irradiation of stem cuttings. Stem cuttings of Hibiscus rosa-sinensis were irradiated at 10, 20, 30 and 60 Gy using a gamma cell with a Co-60 source at a dose rate of 1.66 Gys -1 . Irradiated stem cuttings were planted in sand-beds and data on the number of growing shoots were taken. Increasing gamma ray doses resulted in a reduction of growing shoots on the irradiated stem cuttings. It was shown that the LD50 for the stem cuttings was 36.2 Gy and at 75% growth was 17.15 Gy. Based on these results, 20 to 30 Gy were chosen for irradiation of the stem cuttings to induce mutation in Hibiscus rosa-sinensis. Irradiated stem cuttings were then planted into sand-beds for rooting. After one month, the rooted stems were transferred into polybags and allowed to grow under 70% shade provided by plastic netting and the variants were subsequently observed. Three variants with variation in flower shapes and colours were obtained. (Author)

Rosa acicularis seed oil was extracted from Rosa acicularis seeds by the ultrasonic-assisted aqueous enzymatic method using cellulase and protease. Based on a single experiment, Plackett-Burman design was applied to ultrasonic-assisted aqueous enzymatic extraction of wild rose seed oil. The effects of enzyme amount, hydrolysis temperature and initial pH on total extraction rate of wild rose seed oil was studied by using Box-Behnken optimize methodology. Chemical characteristics of a sample of Rosa acicularis seeds and Rosa acicularis seed oil were characterized in this work. The tocopherol content was 200.6±0.3 mg/100 g oil. The Rosa acicularis seed oil was rich in linoleic acid (56.5%) and oleic acid (34.2%). The saturated fatty acids included palmitic acid (4%) and stearic acid (2.9%). The major fatty acids in the sn-2 position of triacylglycerol in Rosa acicularis oil were linoleic acid (60.6%), oleic acid (33.6%) and linolenic acid (3.2%). According to the 1,3-random-2-random hypothesis, the dominant triacylglycerols were LLL (18%), LLnL (1%), LLP (2%), LOL (10%), LLSt (1.2%), PLP (0.2%), LLnP (0.1%), LLnO (0.6%) and LOP (1.1%). This work could be useful for developing applications for Rosa acicularis seed oil.

Full Text Available Rosa rugosa petals are a rich source of phenolic compounds, which determined their antioxidant properties. The aim of this study was to determine the polyphenolic composition of not processed petals of Rosa rugosa collected from the commodity crops and to determine the variability of the contained therein polyphenols between harvesting seasons. Twenty polyphenols were identified by UPLC-ESI-MS. The main fraction of polyphenols was ellagitannins, which are 69 to 74% of the total polyphenols of the petals. In the petals of Rosa rugosa, four anthocyanins have been identified: cyanidin 3,5-di-O-glucoside, peonidin 3-O-sophoroside, peonidin 3,5-di-O-glucoside, and peonidin 3-O-glucoside, of which the predominant peonidin 3,5-di-O-glucoside represented approx. 85% of all the determined anthocyanin compounds. It was found that the petals of Rosa rugosa are a valuable source of bioactive compounds and can be considered as a healthy valuable resource.

FLUVIAL PROCESSES IN ATTACHMENT BARS IN THE UPPER PARANÁ RIVER, BRAZIL

Directory of Open Access Journals (Sweden)

Vanessa Cristina Dos Santos

2017-08-01

Full Text Available Bars are semi-submerged fluvial forms associated with the availability of sediments and a temporal dynamic, whose dimensions are controlled by the flow and depth of the channel.  Attachment bars are very common in large anabranching river systems and play an important role in island formation and ecology. The Upper Paraná River exhibits an anabranching pattern characterized by channels of different sizes, separated by islands and bars. The objective of this work is to present the processes involved in the formation and development of attachment bars in Santa Rosa Island, situated in Porto Rico, State of Parana, Southern Brazil. Acquisition campaigns were performed to obtain data on channel hydraulics (ADCP equipment, morphometry (Echo-sound profiles and textural parameters (grain-size analyses at high and medium water levels. Santa Rosa Island divides the flow into two channels of distinct hydraulic and sedimentary dynamics. Flow diversion produces a decrease in flow velocity and consequent sediment deposition near the upstream end of Santa Rosa Island. The formation and maintenance of attachment bars in Santa Rosa Island is related to flow competence reduction and the occurrence of divergent currents. Vegetation cover and flow regime control its permanence. 

Crustal-scale tilting of the central Salton block, southern California

Science.gov (United States)

Dorsey, Rebecca; Langenheim, Victoria

2015-01-01

The southern San Andreas fault system (California, USA) provides an excellent natural laboratory for studying the controls on vertical crustal motions related to strike-slip deformation. Here we present geologic, geomorphic, and gravity data that provide evidence for active northeastward tilting of the Santa Rosa Mountains and southern Coachella Valley about a horizontal axis oriented parallel to the San Jacinto and San Andreas faults. The Santa Rosa fault, a strand of the San Jacinto fault zone, is a large southwest-dipping normal fault on the west flank of the Santa Rosa Mountains that displays well-developed triangular facets, narrow footwall canyons, and steep hanging-wall alluvial fans. Geologic and geomorphic data reveal ongoing footwall uplift in the southern Santa Rosa Mountains, and gravity data suggest total vertical separation of ∼5.0–6.5 km from the range crest to the base of the Clark Valley basin. The northeast side of the Santa Rosa Mountains has a gentler topographic gradient, large alluvial fans, no major active faults, and tilted inactive late Pleistocene fan surfaces that are deeply incised by modern upper fan channels. Sediments beneath the Coachella Valley thicken gradually northeast to a depth of ∼4–5 km at an abrupt boundary at the San Andreas fault. These features all record crustal-scale tilting to the northeast that likely started when the San Jacinto fault zone initiated ca. 1.2 Ma. Tilting appears to be driven by oblique shortening and loading across a northeast-dipping southern San Andreas fault, consistent with the results of a recent boundary-element modeling study.

Among the highly fragrant Rosa species, Rosa gruss an teplitz and Rosa centifolia have high value in terms of commercial importance and economical trade. However, the absence of floral diversification and diversity in color patterns in these species acts as limiting factors in floriculture trade of these species. In the present study, we aimed to induce mutations using gamma radiations up to 120 Gy to observe the rate and the correlated effects on the several plant traits in micropropagated shoot tips of Rosa gruss an teplitz and Rosa centifolia. Irradiated shoot tips were micropropagated for one culture cycle and were acclimatized in a green house after in vitro rooting. Plants of irradiated population at 60 and 30 Gy showed 78.12 and 38.50 percentage less culture rooting percentage age as well as 23.82 and 7 percentage less flower size as compared to non irradiated population of Rosa gruss an teplitz and Rosa centifolia respectively. Moreover, flower color component a* (+ redness - green, 36.16 and 27.16) and chroma (37.77 and 27.5) depicted minimum while L* (Lightness, 45.12 and 76.64), b* (+ yellow - blue, 10.69 and -4.14) and hue angle (17.1 and -8.58) maximum value. Apart from these variations, mutants of Rosa gruss an teplitz also produced variegated, pink color and different shape flowers. Genetic variations observed among the putative mutants of Rosa gruss an teplitz and Rosa centifolia were evaluated using twelve decamer RAPD primers. Phylogenetic inferences showed large genetic diversity in putative mutants as compared to mother plant. (author)

Development and evaluation of an office ergonomic risk checklist: ROSA--rapid office strain assessment.

Science.gov (United States)

Sonne, Michael; Villalta, Dino L; Andrews, David M

2012-01-01

The Rapid Office Strain Assessment (ROSA) was designed to quickly quantify risks associated with computer work and to establish an action level for change based on reports of worker discomfort. Computer use risk factors were identified in previous research and standards on office design for the chair, monitor, telephone, keyboard and mouse. The risk factors were diagrammed and coded as increasing scores from 1 to 3. ROSA final scores ranged in magnitude from 1 to 10, with each successive score representing an increased presence of risk factors. Total body discomfort and ROSA final scores for 72 office workstations were significantly correlated (R = 0.384). ROSA final scores exhibited high inter- and intra-observer reliability (ICCs of 0.88 and 0.91, respectively). Mean discomfort increased with increasing ROSA scores, with a significant difference occurring between scores of 3 and 5 (out of 10). A ROSA final score of 5 might therefore be useful as an action level indicating when immediate change is necessary. ROSA proved to be an effective and reliable method for identifying computer use risk factors related to discomfort. Copyright © 2011 Elsevier Ltd and The Ergonomics Society. All rights reserved.

Supracrustal rocks of the Santa Terezinha de Goias region, Central Brazil, presumably represent a southern extension of the Mara Rosa magmatic arc tectonically juxtaposed to Archean terrains and consist of a meta volcanic unit and a meta sedimentary unit. The aim of the paper is to present and discuss the first U-Pb and Sm-Nd data of rocks belonging to both units of that region. U-Pb data of zircons from a felsic meta volcanic rock inter layered with chlorite-rich schists (metandesites?) yield a concordant age of of 660 My, while the Sm-Nd model age of a variety of chlorite-schists indicate a juvenile age between 1.1 and 1.3 Ga. These data indicate that the meta volcanic rocks are Neo proterozoic in age and may be correlated with rocks of the Mara Rosa magmatic arc. On the other hand, the prevailing provenance of rocks belonging to the meta sedimentary unit indicate a Paleoproterozoic, or older, source. Thus, the deposition of both units are explained by means of the erosion of source-areas of variable age. (author)

Roses are one of the most important groups of ornamental plants and their fruits and flowers are used in a wide variety of food, nutritional products and different traditional medicines. The antioxidant activity of methanolic extracts from fresh flowers of three rose species (Rosa damascena, Rosa bourboniana and Rosa brunonii) was evaluated by 1,1-diphenyl-2-picryl hydrazyl (DPPH) free-radical method. The ability to scavenge DPPH radical was measured by the discoloration of the solution. The methanolic extract from R. brunonii exhibited maximum free-radical-scavenging activity (64.5+/-0.38%) followed by R. bourboniana (51.8+/-0.46%) and R. damascena (43.6+/-0.25%) at 100 microg/ml. Simultaneously, ultra-performance liquid chromatography coupled with electrospray ionization-quadrupole time-of-flight mass spectrometry (UPLC-ESI-QTOF-MS) was used to study phenolic composition in the methanolic extracts from the fresh flowers of rose species. The phenolic constituents were further investigated by direct infusion-ESI-QTOF-MS/MS in negative ion mode. Characteristic Electrospray ionization tandem mass spectrometry (ESI-MS/MS) spectra with other diagnostic fragment ions generated by retro Diels-Alder (RDA) fragmentation pathways were recorded for the flavonoids. Distinct similarities were observed in the relative distribution of polyphenolic compounds among the three species. The dominance of quercetin, kaempferol and their glycosides was observed in all the three species.

The Dmp1-SOST Transgene Interacts With and Downregulates the Dmp1-Cre Transgene and the Rosa(Notch) Allele.

Zanotti, Stefano; Canalis, Ernesto

2016-05-01

Activation of Notch1 in osteocytes of Rosa(Notch) mice, where a loxP-flanked STOP cassette and the Nicd coding sequence were targeted to the reverse orientation splice acceptor (Rosa)26 locus, causes osteopetrosis associated with suppressed Sost expression and enhanced Wnt signaling. To determine whether Sost downregulation mediates the effects of Notch activation in osteocytes, Rosa(Notch) mice were crossed with transgenics expressing Cre recombinase or SOST under the control of the dentin matrix protein (Dmp)1 promoter. Dmp1-SOST transgenics displayed vertebral osteopenia and a modest femoral cancellous and cortical bone phenotype, whereas hemizygous Dmp1-Cre transgenics heterozygous for the Rosa(Notch) allele (Dmp1-Cre;Rosa(Notch)) exhibited osteopetrosis. The phenotype of Notch activation in osteocytes was prevented in Dmp1-Cre;Rosa(Notch) mice hemizygous for the Dmp1-SOST transgene. The effect was associated with downregulated Notch signaling and suppressed Dmp1 and Rosa26 expression. To test whether SOST regulates Notch expression in osteocytes, cortical bone cultures from Dmp1-Cre;Rosa(Notch) mice or from Rosa(Notch) control littermates were exposed to recombinant human SOST. The addition of SOST had only modest effects on Notch target gene mRNA levels and suppressed Dmp1, but not Cre or Rosa26, expression. These findings suggest that prevention of the Dmp1-Cre;Rosa(Notch) skeletal phenotype by Dmp1-SOST is not secondary to SOST expression but to interactions among the Dmp1-SOST and Dmp1-Cre transgenes and the Rosa26 locus. In conclusion, the Dmp1-SOST transgene suppresses the expression of the Dmp1-Cre transgene and of Rosa26. © 2015 Wiley Periodicals, Inc.

The aim of this study was to compare phenolic profile, vitamin C content, antioxidant, anti-inflammatory and cytotoxic activity of rose hips and the preserves (purée and jam) of two Rosa species: renowned Rosa canina L. and unexplored Rosa arvensis Huds. The liquid chromatography-tandem mass spectrometry analysis of 45 phenolics resulted in quantification of 14 compounds, with quercitrin, gallic and protocatechuic acids as the most dominant. High antioxidant potential of R. canina and a moderate activity of R. arvensis extracts were determined through several assays. Purée of both species and methanol extract of air-dried R. canina hips showed some anti-inflammatory (cyclooxygenase-1 and 12-lipooxygense inhibition potency) activity. Purée of R. canina exerted cytotoxic activity only against the HeLa cell line among several others (HeLa, MCF7, HT-29 and MRC-5). The presented results support traditional use of rose hips and their fruit preserves as food with health and nutritional benefits. Copyright © 2015 Elsevier Ltd. All rights reserved.

The report presents characteristic test results about the steady state heat loss, one of the inherent characteristics of the ROSA-III test facility. The steady state heat loss tests were conducted at five different temperature conditions between 111 0 C and 290 0 C . Net heat loss rates were obtained by estimating the electric power supplied to the core, heat input from the recirculation pumps and steam leakage rate. The heat loss characteristics have important contribution to analyses of the ROSA-III small break tests. A following simple relation was obtained between the net heat loss rate Q*sub(HL) (kJ/s) (*: radical) of the ROSA-III facility and the temperature difference ΔT ( 0 C) between the fluid temperature of the system and the room temperature, Q*sub(HL) = 0.56 x ΔT. (*: radical) And the steam leak flow at normal operating condition of the ROSA-III test, (P = 7.2 MPa) was obtained as 8.9 x 10 -3 kg/s and corresponding steam leakage energy as 10.5 kJ/s. The heat input from the recirculation pumps was indirectly estimated under a constant speed by assuming the heat input was equal to the brake horce power of the pumps. (author)

2016-01-01

The Rapid Office Strain Assessment (ROSA) was developed to assess musculoskeletal disorder (MSD) risk factors for computer workstations. This study examined the validity and reliability of remotely conducted, photo-based assessments using ROSA. Twenty-three office workstations were assessed on-site by an ergonomist, and 5 photos were obtained. Photo-based assessments were conducted by three ergonomists. The sensitivity and specificity of the photo-based assessors' ability to correctly classify workstations was 79% and 55%, respectively. The moderate specificity associated with false positive errors committed by the assessors could lead to unnecessary costs to the employer. Error between on-site and photo-based final scores was a considerable ∼2 points on the 10-point ROSA scale (RMSE = 2.3), with a moderate relationship (ρ = 0.33). Interrater reliability ranged from fairly good to excellent (ICC = 0.667-0.856) and was comparable to previous results. Sources of error include the parallax effect, poor estimations of small joint (e.g. hand/wrist) angles, and boundary errors in postural binning. While this method demonstrated potential validity, further improvements should be made with respect to photo-collection and other protocols for remotely-based ROSA assessments.

Expression of transgenes targeted to the Gt(ROSA26Sor locus is orientation dependent.

Directory of Open Access Journals (Sweden)

Douglas Strathdee

2006-12-01

Full Text Available Targeting transgenes to a chosen location in the genome has a number of advantages. A single copy of the DNA construct can be inserted by targeting into regions of chromatin that allow the desired developmental and tissue-specific expression of the transgene.In order to develop a reliable system for reproducibly expressing transgenes it was decided to insert constructs at the Gt(ROSA26Sor locus. A cytomegalovirus (CMV promoter was used to drive expression of the Tetracycline (tet transcriptional activator, rtTA2(s-M2, and test the effectiveness of using the ROSA26 locus to allow transgene expression. The tet operator construct was inserted into one allele of ROSA26 and a tet responder construct controlling expression of EGFP was inserted into the other allele.Expression of the targeted transgenes was shown to be affected by both the presence of selectable marker cassettes and by the orientation of the transgenes with respect to the endogenous ROSA26 promoter. These results suggest that transcriptional interference from the endogenous gene promoter or from promoters in the selectable marker cassettes may be affecting transgene expression at the locus. Additionally we have been able to determine the optimal orientation for transgene expression at the ROSA26 locus.

For the perfume industry, Rosa damascena is the most important species used in the production of rose attar which is made by distilling volatile oils from the petals of flowers. It is also used widely in the production of rose water, a flavoring agent. Other species like R. gallica L., R. centifolia L., R. bourboniana and Gruss an Teplitz also exhibit the fragrance that is sought by perfumeries in the world. Eight land races of Damask rose along with related Rosa species were collected from Punjab province and evaluated to determine the diversity on the basis of morphology and oil yield. The investigated characters were flower weight, flower diameter, peduncle length, number of petals, number of stamens and oil content. Pearson's coefficients showed a negative association of flower weight with peduncle length (r = -0.3348) and a positive and strong correlation was observed for flower weight with the all other morphological characters. Flower diameter showed a positive but weak correlation with peduncle length, number of petals and number of stamens with the values of r = 0.0733, r 0.5302 and r = 0.1241, respectively. Oil content (%) was measured from the Rosa species by using Soxhlet extractor with N-hexane. R. damascena land race from Choha Syedan Shah produced the highest oil content of absolute oil (0.147%) on petal basis while the lowest value for absolute oil content was 0.36% from R. indica. Dendrogram created by cluster analysis for morphological characters, indicated no relationship of genetic variation with their collection sites. This study has revealed that the selection of land races for their specific characteristic could be possible for future breeding program. It also provides practical information for the future collection of Damask rose germplasm and breeding program. (author)

Gamma irradiation is an alternative method to create new cultivars of Hibiscus rosa-sinensis in Malaysia. Increasing gamma ray doses resulted in a reduction of growing shoots on the irradiated stem cuttings. The LD50 for the stem cuttings was 36.2 Gy and at 75% growth was 17.15 Gy. Based on these results, 20 to 30 Gy were chosen for irradiation of the stem cuttings to induce mutation in Hibiscus rosa-sinensis. Irradiated stem cuttings were then planted into sand-beds for rooting. After one month, the rooted stems were transferred into polybags and allowed to grow under 70% shade provided by plastic netting and the variants were subsequently observed. Three new cultivars with variations in flower size and colours were obtained. The plants were propagated for five generations to achieve the stable mutants. Anthocyanins analysis is being carried out to measure the amount of anthocyanins in each cultivar. Pelargonidin chloride, Cyanidin chloride and Delphinidin chloride are used as standards for the analysis. (Author)

Tocopherols in rose hips (Rosa spp.) during ripening.

Science.gov (United States)

Andersson, Staffan C; Olsson, Marie E; Gustavsson, Karl-Erik; Johansson, Eva; Rumpunen, Kimmo

2012-08-15

Rose hips are used as a food ingredient and in health products. They are rich in various bioactive compounds such as carotenoids and vitamin C, but data on their vitamin E content (tocopherols and tocotrienols) are limited. In this study, four different species of Rosa were analysed for tocopherol and tocotrienol content during ripening in three different years. Only α- and γ-tocopherol were found in the fleshy parts of the rose hips, and the tocopherol content and vitamin E activity varied depending on date of harvesting, species and year. The amount of vitamin E activity differed between species of Rosa and years, whereas the changes during ripening were relatively small. The choice of species must be considered if tocopherol content is to be optimised when rose hips are used as a food ingredient. Copyright © 2012 Society of Chemical Industry.

Full Text Available Em condições de campo, realizaram-se seleções em linhagens de soja contra manchamento de sementes causado pelo vírus do mosaico comum da soja (VMCS. Conhecido como "mancha-café", o sintoma caracteriza-se pelo derramamento dos pigmentos do hilo da semente. Produzidas no Centro Experimental de Campinas, pertencente ao IAC, as sementes de 131 linhagens da geração F5 do cruzamento entre IAC78-2318 e 'Santa Rosa' (ambos suscetíveis ao VMCS foram avaliadas, em 1987, quanto ao grau de manchamento, de acordo com uma escala de notas de 1 (sementes sem manchas a 5 (sementes com tegumento quase totalmente manchado. Quatro linhagens obtiveram nota 1, enquanto a maioria recebeu nota 3. Essa distribuição de notas pode indicar que a herança da resistência ao manchamento da semente é de origem poligênica. Para verificar a repetibilidade do manchamento, em 1988, nas mesmas condições, procedeu-se ao ensaio com dezessete linhagens avaliadas no ano anterior mais o cultivar Santa Rosa, representando as cinco notas. Houve similaridade entre as notas nos dois anos, sendo o valor do coeficiente de correlação (r igual a 0,96, altamente significativo. Para estudar o efeito da inoculação do vírus em três estádios fenológicos em linhagens e cultivares, realizou-se, em 1992, um experimento em casa de vegetação.

Recent discovery of a method for derivation and culture of germline-competent rat pluripotent stem cells (PSCs) enables generation of transgenic rats or knock-out rats via genetic modification of such PSCs. This opens the way to use rats, as is routine in mice, for analyses of gene functions or physiological features. In mouse or human, one widely used technique to express a gene of interest stably and ubiquitously is to insert that gene into the Rosa26 locus via gene targeting of PSCs. Rosa26 knock-in mice conditionally expressing a reporter or a toxin gene have contributed to tracing or ablation of specific cell lineages. We successfully identified a rat orthologue of the mouse Rosa26 locus. Insertion of tdTomato, a variant of red fluorescent protein, into the Rosa26 locus of PSCs of various rat strains allows ubiquitous expression of tdTomato. Through germline transmission of one Rosa26-tdTomato knock-in embryonic stem cell line, we also obtained tdTomato knock-in rats. These expressed tdTomato ubiquitously throughout their bodies, which indicates that the rat Rosa26 locus conserves functions of its orthologues in mouse and human. The new tools described here (targeting vectors, knock-in PSCs, and rats) should be useful for a variety of research using rats.

A separate effect test on spray cooling was carried out using one core channel of ROSA-III BWR LOCA test facility. This report describes a heating experiment in the series of runs. (1) The cooling from top of the core by spray easily causes countercurrent flow limit due to the vaparization of falling water itself, so it becomes in effective. (2) The cooling by falling water is irregular and unstable. Therefore, the cooling by the falling water is not to be relied on. (3) CCFL at porous plate is hard to occur, compared with single pipe. A quantitative study of this is desired to evaluate reflooding rate. Some suggestions for ROSA-III design are also made. (author)

This report presents the experimental data of 2.8% suction line break test RUN 984 at ROSA-III, which was conducted as one of counterpart tests to FIST program sponsored by GE, EPRI and USNRC. The similarity study between the ROSA-III and FIST tests is on the way. The report also presents the information on the ROSA-III test facility, experiment results and the effects of the ADS flow rate and the MSIV trip level comparing with the previously conducted ROSA-III small break tests, RUNs 920 and 922. Major conclusions obtained are as follows. (1) Change of the MSIV trip level from L2 to L1 gives delay of MSIV closure and longer actuation of pressure control system in a small break LOCA. (2) Larger ADS flow gives faster depressurization rate and earlier ECCS actuation, which results in shorter fuel rod dryout period and lower PCT. (author)

Research highlights: → Verification of a TRACE input deck for the EPR TM generation III PWR. → Scaling simulation of an SBLOCA experiment of the integral test facility ROSA/LSTF. → The EPR TM model was compared with the TRACE results of the ROSA/LSTF model. - Abstract: In cooperation with the Finnish Radiation and Nuclear Safety Authority (STUK), a project has been launched at the Paul Scherrer Institute (PSI) aimed at performing safety evaluations of the Olkiluoto-3 nuclear power plant (NPP), the first EPR TM , a generation III pressurizer water reactor (PWR); with particular emphasis on small-and large-break loss-of-coolant-accidents (SB/LB-LOCAs) and main steam-line breaks. As a first step of this work, the best estimate system code TRACE has been used to develop a model of Olkiluoto-3. In order to test the nodalization, a scaling calculation from the rig of safety assessment (ROSA) test facility has been performed. The ROSA large scale test facility (LSTF) was built to simulate Westinghouse design pressurized water reactors (PWR) with a four-loop configuration. Even though there are differences between the EPR TM and the Westinghouse designs, the number of similarities is large enough to carry out scaling calculations on SBLOCA and LOCA cases from the ROSA facility; as a matter of fact, the main differences are located in the secondary side. Test 6-1 of the ROSA 1 programme, an SBLOCA with the break situated in the upper head of the reactor pressure vessel (RPV), was of special interest since a very good agreement with the experiment was obtained with a TRACE input deck. In order to perform such scaling calculation, the set-points of the secondary relief and safety valves in the EPR TM nodalization had to be changed to those used in the ROSA facility, the break size and the core power had to be scaled by a factor of 60 (according to the core power and core volume) and the pumps coast down had to be adapted to the ones of the test. The calculation showed

Full Text Available The present article pays attention, in the first place, to the new conditions which provide a wide reception of the East Asian literature in the western area. Coming up next, in this context, a study of the poetries of Rosa Romojaro has been carried out, from the key points and compared motives, especially with the Chinese lyrical poetries and its tradition. After presenting the creative work of Rosa Romojaro, one of the most outstanding Spanish poets nowadays, standing on the point of view of a Chinese original critic, fundamental motives are given in advance in the chosen texts, and constantly linking with the Asian canon: so as the nature, and the degree of the symbolic subtlety in the writing of the poet according to the eastern point of view; the feeling of “Hen”, which contains the emotion of bittersweet and also associates with the passage of time; the essence of the poems and every word of hers, which is fulfilled with sentiments; the symbolism of the moon and its metaphorical reflections of the nocturne; the great motive of voyage and motions, and attached to them, the hope and the seasons, the fall; the adventure of  discovery within the heart of the known places and the purity driven by her glance; the synesthetic evocations; and, lastly, the relationship of her poems with the vital prolongation, making up every poem of Rosa Romojaro in a center of expressivity shared with universal motives which look up to the tradition and the modernity.

Full Text Available Abstract Background Roses (Rosa sp., which belong to the family Rosaceae, are the most economically important ornamental plants—making up 30% of the floriculture market. However, given high demand for roses, rose breeding programs are limited in molecular resources which can greatly enhance and speed breeding efforts. A better understanding of important genes that contribute to important floral development and desired phenotypes will lead to improved rose cultivars. For this study, we analyzed rose miRNAs and the rose flower transcriptome in order to generate a database to expound upon current knowledge regarding regulation of important floral characteristics. A rose genetic database will enable comprehensive analysis of gene expression and regulation via miRNA among different Rosa cultivars. Results We produced more than 0.5 million reads from expressed sequences, totalling more than 110 million bp. From these, we generated 35,657, 31,434, 34,725, and 39,722 flower unigenes from Rosa hybrid: ‘Vital’, ‘Maroussia’, and ‘Sympathy’ and Rosa rugosa Thunb. , respectively. The unigenes were assigned functional annotations, domains, metabolic pathways, Gene Ontology (GO terms, Plant Ontology (PO terms, and MIPS Functional Catalogue (FunCat terms. Rose flower transcripts were compared with genes from whole genome sequences of Rosaceae members (apple, strawberry, and peach and grape. We also produced approximately 40 million small RNA reads from flower tissue for Rosa, representing 267 unique miRNA tags. Among identified miRNAs, 25 of them were novel and 242 of them were conserved miRNAs. Statistical analyses of miRNA profiles revealed both shared and species-specific miRNAs, which presumably effect flower development and phenotypes. Conclusions In this study, we constructed a Rose miRNA and transcriptome database, and we analyzed the miRNAs and transcriptome generated from the flower tissues of four Rosa cultivars. The database provides a

It has recently been described that the Japanese plum "Santa Rosa" bud sport series contains variations in ripening pattern: climacteric, suppressed-climacteric and non-climacteric types. This provides an interesting model to study the role of ethylene and other key mechanisms governing fruit ripening, softening and senescence. The aim of the current study was to investigate such differences at the genomic level, using this series of plum bud sports, with special reference to genes involved in ethylene biosynthesis, signal transduction, and sugar metabolism. Genomic DNA, isolated from leaf samples of six Japanese plum cultivars ("Santa Rosa", "July Santa Rosa", "Late Santa Rosa", "Sweet Miriam", "Roysum", and "Casselman"), was used to construct paired-end standard Illumina libraries. Sequences were aligned to the Prunus persica genome, and genomic variations (SNPs, INDELS, and CNV's) were investigated. Results determined 12 potential candidate genes with significant copy number variation (CNV), being associated with ethylene perception and signal transduction components. Additionally, the Maximum Likelihood (ML) phylogenetic tree showed two sorbitol dehydrogenase genes grouping into a distinct clade, indicating that this natural group is well-defined and presents high sequence identity among its members. In contrast, the ethylene group, which includes ACO1, ACS1, ACS4, ACS5, CTR1, ERF1, ERF3, and ethylene-receptor genes, was widely distributed and clustered into 10 different groups. Thus, ACS, ERF, and sorbitol dehydrogenase proteins potentially share a common ancestor for different plant genomes, while the expansion rate may be related to ancestral expansion rather than species-specific events. Based on the distribution of the clades, we suggest that gene function diversification for the ripening pathway occurred prior to family extension. We herein report all the frameshift mutations in genes involved in sugar transport and ethylene biosynthesis detected as well

Purpose The Hibiscus rosa-sinensis flower is widely used in Brazilian traditional medicine for the treatment of diabetes and has shown antifertility activity in female Wistar rats. However, there is no scientific confirmation of its effect on diabetes and pregnancy. The aim of this study was evaluate the effect of aqueous extract of H. rosa-sinensis flowers on maternal-fetal outcome in pregnant rats with diabetes. Methods Diabetes was induced by streptozotocin (STZ, 40 mg/kg) in virgin, adult, female Wistar rats. After diabetes induction, the rats were mated. The pregnant rats were distributed into four groups (n minimum = 11 animals/group): non-diabetic, non-diabetic treated, diabetic, and diabetic treated. Oral aqueous extract of Hibiscus rosa-sinensis was administered to rats in the treatment groups during pregnancy. At term pregnancy, maternal reproductive outcomes, fetal parameters, and biochemical parameters were analyzed. Results The non-diabetic treated group showed decreased high density lipoprotein cholesterol, increased atherogenic index (AI) and coronary artery risk index (CRI), and increased preimplantation loss rate compared to the non-diabetic group. Although treatment with H. rosa-sinensis led to no toxicity, it showed deleterious effects on cardiac and reproductive functions. However, the diabetic treated group showed increased maternal and fetal weights, reduced AI and CRI, and reduced preimplantation loss rate compared to the untreated diabetic group. Conclusion Our results demonstrate beneficial effects of this flower only in pregnant rats with diabetes and their offspring. Although these findings cannot be extrapolated to human clinical use, they show that the indiscriminate intake of H. rosa-sinensis may be harmful to healthy individuals and its use should be completely avoided in pregnancy.

A set of 10 microsatellite markers was used to survey the levels of genetic variability and to analyse the genetic aspects of the population dynamics of two potentially invasive pest fruit fly species, Ceratitis rosa and C. fasciventris, in Africa. The loci were derived from the closely related species, C. capitata. The degree of microsatellite polymorphism in C. rosa and C. fasciventris was extensive and comparable to that of C. capitata. In C. rosa, the evolution of microsatellite polymorphism in its distribution area reflects the colonization history of this species. The mainland populations are more polymorphic than the island populations. Low levels of differentiation were found within the Africa mainland area, while greater levels of differentiation affect the islands. Ceratitis fasciventris is a central-east African species. The microsatellite data over the Uganda/Kenya spatial scale suggest a recent expansion and possibly continuing gene flow within this area. The microsatellite variability data from C. rosa and C. fasciventris, together with those of C. capitata, support the hypothesis of an east African origin of the Ceratitis spp.

Some of the volcano-sedimentary sequences of the Tocantins Province have been considered to be formed during the evolution of a Neoproterozoic intra oceanic island arc system (Pimentel et al., 2000). However, the interpretation of supra crustal rocks of some areas of the central portions of the Goias Massif, such as the region of Santa Terezinha de Goias, is still controversial. These rocks have been considered either as part of the Archean greenstone belts or as Paleoproterozoic sequences (Ribeiro Filho 1981, Souza and Le Neto 1981, Machado et al.1981, Ribeiro Filho and Lacerda Filho 1985, Biondi and Pidevin 1994, Arantes et al. 1991) rather than an extension of the Neoproterozoic Mara Rosa magmatic arc (Viana et al.1995, Pimentel et al. 1997). An area of about 800 km 2 near the town of Santa Terezinha de Goias was recently mapped on a 1:25.000 scale (Jost et al. 2001). Its northern part consists of Proterozoic supra crustal rocks in tectonic contact with Archean rocks in the south. We present new Sm-Nd and U-Pb zircon data for the supra crustal rocks that crop out in the northern part of the area and discuss their provenance and depositional age (au)

Medical textbooks are an important teaching supplement. Few have junior doctors or medical students ('juniors') as primary contributors. However, the strengths of junior-led face-to-face teaching are now well-established, and we hypothesized that similar advantages would be transferrable to a textbook setting. Juniors were approached to contribute to an independently published medical textbook, with senior clinicians recruited in parallel to ensure factual accuracy. Juniors directed every aspect of textbook writing and the production process. The published book stressed that it was an open collaboration with readers, inviting them to get in touch to evaluate the text and suggest ideas for new titles. Of 75 respondents, 93 % awarded the first textbook in the series 4 or 5 out of 5 for overall quality. Five other titles have been released, with seven more in development. Over 100 juniors are currently involved, with two students progressing from reviewers to editors after less than a year of mentorship. Juniors can be a motivated, dynamic, innovative group, capable of significant contributions to the medical textbook literature. This initiative has generated a sustainable infrastructure to facilitate junior-led publishing, and has the capacity for expansion to accommodate new initiatives and ideas.

Highlights: • TRACE modelization for PKL and ROSA/LSTF installations. • Secondary-side depressurization as accident management action. • CET vs PCT relation. • Analysis of differences in the vessel models. - Abstract: Experimental facilities are scaled models of commercial nuclear power plants, and are of great importance to improve nuclear power plants safety. Thus, the results obtained in the experiments undertaken in such facilities are essential to develop and improve the models implemented in the thermal-hydraulic codes, which are used in safety analysis. The experiments and inter-comparisons of the simulated results are usually performed in the frame of international programmes in which different groups of several countries simulate the behaviour of the plant under the accidental conditions established, using different codes and models. The results obtained are compared and studied to improve the knowledge on codes performance and nuclear safety. Thus, the Nuclear Energy Agency (NEA), in the nuclear safety work area, auspices several programmes which involve experiments in different experimental facilities. Among the experiments proposed in NEA programmes, one on them consisted of performing a counterpart test between ROSA/LSTF and PKL facilities, with the main objective of determining the effectiveness of late accident management actions in a small break loss of coolant accident (SBLOCA). This study was proposed as a result of the conclusion obtained by the NEA Working Group on the Analysis and Management of Accidents, which analyzed different installations and observed differences in the measurements of core exit temperature (CET) and maximum peak cladding temperature (PCT). In particular, the transient consists of a small break loss of coolant accident (SBLOCA) in a hot leg with additional failure of safety systems but with accident management measures (AM), consisting of a fast secondary-side depressurization, activated by the CET.

In the ROSA (Rig of Safety Assessment) program, the digital computer code DEPCO-SINGLE and DEPCO-MULTI (Subcooled Decompression Process in Loss-of-Coolant Accident - Single Pipe and - Multiple Pipe Network) were prepared to study thermo-hydraulic behavior of the primary coolant in subcooled decompression of the PWR LOCA. The analytical results with DEPCO-MULTI on the subcooled decompression phenomena are presented for ROSA-I, ROSA-II and LOFT 500, 600, 700 and 800 series experiments. The effects of space mesh length, elasticity of pressure boundary materials and simplification for computational piping system on the computed result are described. This will be the final work on the study of the subcooled decompression analysis as for the ROSA program, and the authors wish that the present code shall further be examined with the data of much advanced experiments.

This report presents the test data of Run 7341 in the single failure test series of the ROSA-III program to conduct the system effect test concerning the response of a BWR during a LOCA with the ECC injection. The ROSA-III test facility is a volumetrically scaled (1/424) system of the BWR/6 with an electrically heated core and the scaled ECCS. Run 7341 is a double-ended break test at the recirculation pump inlet with the assumption that all ECCS function as designed. The test is initiated with the steam dome pressure of 7.28 MPa, the lower plenum subcooling of 11.0 K, the core inlet flow rate of 15.3 kg/s, and the core heat generation rate of 3.55 MW and proceeded as planned. The whole core is quenched after the ECCS actuation and the maximum fuel cladding temperature is 810 K. The effectiveness of ECC injection has been clarified from the comparison of the test results with those of the other test in the series without ECCS. (author)

Rosa canina Extracts Have Antiproliferative and Antioxidant Effects on Caco-2 Human Colon Cancer.

Sandra Jiménez

Full Text Available The in vitro antiproliferative and antioxidant effects of different fractions of Rosa canina hips on human colon cancer cell lines (Caco-2 was studied. The compounds tested were total extract (fraction 1, vitamin C (fraction 2, neutral polyphenols (fraction 3 and acidic polyphenols (fraction 4. All the extracts showed high cytotoxicity after 72 h, both low and high concentrations. The flow cytometric analysis revealed that all the fractions produce disturbances in the cell cycle resulting in a concomitant cell death by an apoptotic pathway. Changes in the redox status of Caco-2 cells in response to Rosa canina hips were determined. Cells were exposed to hydrogen peroxide in presence of plant fractions and the production of Reactive Oxygen Species (ROS was significantly decreased. Therefore, our data demonstrate that rosehip extracts are a powerful antioxidant that produces an antiproliferative effect in Caco-2 cells. Therefore, these results predict a promising future for Rosa canina as a therapeutic agent. Thus, this natural plant could be an effective component of functional foods addressed towards colorectal carcinoma.

Full Text Available Resumen: Las novelas de Corín Tellado marcaron la vida de varias generaciones de mujeres y también de muchos hombres. Sufrió los reproches habituales a la novela comercial y de éxito, además del desprecio dedicado a la llamada novela rosa al ser considerada un género menor y fundamentalmente para mujeres. En este artículo nos proponemos analizar cómo con frecuencia ese tipo de juicios no son literarios sino sociales, juicios sociales denegados. Además, estudiaremos las novelas de Corín Tellado, que influyeron enormemente en la “educación sentimental” de las mujeres durante el franquismo, y analizaremos el modelo de mujer que presentan. Abstract: The novels of Corín Tellado marked the life of several generations of women, as well as of many men. She suffered the criticisms habitually levelled at commercially successful novels, especially the so-called novela rosa, or popular romance novel, because of its reputation as a minor genre aimed primarily at women. This paper aims to show that these judgments are often not literary but social. The paper will also examine Corín Tellado's novels, which greatly influenced the 'sentimental education' of women during the Franco regime, and we will analyze the models of woman that theses romances present.

Objective: To investigate the wound-healing potency of the ethanolic extract of the flowers of Hibiscus rosa sinensis. Materials and Methods: The wound-healing activity of H. rosa sinensis (5 and 10% w/w) on Wistar albino rats was studied using three different models viz., excision, incision and dead space wound. The parameters studied were breaking strength in incision model, granulation tissue dry weight, breaking strength and collagen content in dead space wound model, percentage of wound contraction and period of epithelization in excision wound model. The granulation tissue formed on days 4, 8, 12, and 16 (post-wound) was used to estimate total collagen, hexosamine, protein, DNA and uronic acid. Data were analyzed by Analysis of Variance (ANOVA) test. P<0.05 was considered statistically significant. Results: The extract increased cellular proliferation and collagen synthesis at the wound site, as evidenced by increase in DNA, total protein and total collagen content of granulation tissues. The extract-treated wounds were found to heal much faster as indicated by improved rates of epithelialization and wound contraction. The extract of H. rosa sinensis significantly (P<0.001) increased the wound-breaking strength in the incision wound model compared to controls. The extract-treated wounds were found to epithelialize faster, and the rate of wound contraction was significantly (P<0.001) increased as compared to control wounds. Wet and dry granulation tissue weights in a dead space wound model increased significantly (P<0.001). There was a significant increase in wound closure rate, tensile strength, dry granuloma weight, wet granuloma weight and decrease in epithelization period in H. rosa sinensis-treated group as compared to control and standard drug-treated groups. Conclusion: The ethanolic extract of H. rosa sinensis had greater wound-healing activity than the nitrofurazone ointment. PMID:23248396

A variety of herbal plants species has been used in traditional medicine. Most of these plants contained several potent bio-active ingredients and nutrients that could give potential positive effects to the health such as antioxidant and antipyretic. Hibiscus rosa sinensis, commonly known as Bunga raya, have similar concoction characteristic to tea which contain antioxidants that help to control cholesterol. In addition, mucilage that was found in the leaves could helps to reduce extreme body heat during fever (which potentially acts as an antipyretic). Therefore, this preliminary study on the fresh and dried H. rosa sinensis leaves was carried out to analyze and identify the nutrients content, anti-oxidants and inorganic material. Total phenolic content (TPC) method was used for both fresh and dried leaves prior to the antioxidant activities of DPPH free radicals scavenging and ferric ion reducing antioxidant power (FRAP) as to confirm the existence of antioxidant constituents. Meanwhile, the composition of heavy metals was studied using inductively coupled plasma mass spectrometry (ICP-MS). The proximate analysis of the fresh leaves showed the presence of moisture content (9.03 %), protein (10.44 %), fat (6.43 %), crude fiber (11.55 %), ash (11.22 %) and carbohydrate (51.33 %). Meanwhile, the inorganic contents are as follows: cadmium (Cd), chromium (Cr), arsenic (As), nickel (Ni), lead (Pb), iron (Fe) and zinc (Zn). Furthermore, the antioxidant activities of FRAP and DPPH showed that dried leaves of H. rosa sinensis was higher than the fresh leaves (p < 0.05) irrespective of any solvent used. The positive correlation between TPC and two other antioxidant activities of DPPH and FRAP (p < 0.05) indicates the presence of antioxidant components in the acetone and water extracts. Therefore, the high availability of essential nutritional component, anti-oxidants and low concentration of hazardous inorganic matter in H. rosa sinensis leaves enable it to be used as one

Dad's in the Garage: Santa Barbara Physicists in the Long 1970s

American physicists faced many challenges in the 1970s: declining research budgets; public skepticism of scientific authority; declining student enrollments; and pressure to shift to topics such as biomedicine, environmental remediation, alternative energy, public housing and transport, and disability technologies. This paper examines the responses to these challenges of a small group of Santa Barbara physicists. While this group is not representative of the American physics profession, the success and failure of their responses to changed conditions tells us something about how American physicists got through the 1970s, and about the origins of some features of American physics today. The three physicists examined here are Philip Wyatt, David Phillips, and Virgil Elings. In the late `60s, Wyatt left a defense think tank to found an instrumentation firm. The Santa Barbara oil spill and other factors pushed that firm toward civilian markets in biomedicine and pollution measurement. Phillips joined Wyatt's firm from UCSB, while also founding his own company, largely to sell electronic devices for parapsychology. Phillips was also the junior partner in a master's of scientific instrumentation degree curriculum founded by Elings in order to save UCSB Physics' graduate program. Through the MSI program, Elings moved into biomedical research and became a serial entrepreneur. By the 1990s, Wyatt, Phillips, and Elings' turn toward academic entrepreneurship, dual military-civilian markets for physics start-ups, and interdisciplinary collaborations between physicists and life scientists were no longer unusual. Together, their journey through the `70s shows how varied the physics' profession's response to crisis was, and how much it pivoted on new interactions between university and industry.

Sand dunes are an important natural buffer between storm impacts and development backing the beach on the Gold Coast of Queensland, Australia. The ability to forecast dune erosion at a prediction horizon of days to a week would allow efficient and timely response to dune erosion in this highly populated area. Towards this goal, we modified an existing probabilistic dune erosion model for use on the Gold Coast. The original model was trained using observations of dune response from Hurricane Ivan on Santa Rosa Island, Florida, USA (Plant and Stockdon 2012. Probabilistic prediction of barrier-island response to hurricanes, Journal of Geophysical Research, 117(F3), F03015). The model relates dune position change to pre-storm dune elevations, dune widths, and beach widths, along with storm surge and run-up using a Bayesian network. The Bayesian approach captures the uncertainty of inputs and predictions through the conditional probabilities between variables. Three versions of the barrier island response Bayesian network were tested for use on the Gold Coast. One network has the same structure as the original and was trained with the Santa Rosa Island data. The second network has a modified design and was trained using only pre- and post-storm data from 1988-2009 for the Gold Coast. The third version of the network has the same design as the second version of the network and was trained with the combined data from the Gold Coast and Santa Rosa Island. The two networks modified for use on the Gold Coast hindcast dune retreat with equal accuracy. Both networks explained 60% of the observed dune retreat variance, which is comparable to the skill observed by Plant and Stockdon (2012) in the initial Bayesian network application at Santa Rosa Island. The new networks improved predictions relative to application of the original network on the Gold Coast. Dune width was the most important morphologic variable in hindcasting dune retreat, while hydrodynamic variables, surge and

Full Text Available A manga (Mangifera indica L. constitui uma importante fonte de compostos bioativos, dentre os quais se destacam os carotenoides e a vitamina C, que contribuem para a promoção da saúde. Vários métodos podem ser utilizados para conservação de alimentos a fim de aproveitar melhor os frutos durante a safra e permitir seu armazenamento fora de época de produção. No entanto, podem alterar a qualidade nutricional do alimento. Dessa forma, sendo o branqueamento e o congelamento métodos que são utilizados no processamento industrial para conservação de polpas de frutas, objetivou-se, neste trabalho, analisar a influência do branqueamento e do congelamento sobre os teores de carotenoides totais e ácido ascórbico em mangas 'Rosa' e 'Espada' em relação ao tempo de armazenamento. As mangas no estádio maduro, após serem colhidas, lavadas, cortadas e despolpadas, foram submetidas ao congelamento (-18ºC ou branqueamento por imersão em água (75ºC, por 3 minutos ou branqueamento por vapor em água fervente, por 3 minutos. Em seguida, foram realizadas as determinações bioquímicas dos teores de carotenoides totais e ácido ascórbico no tempo zero e após 20; 40 e 60 dias de armazenamento sob congelamento. Após análise dos resultados obtidos, conclui-se que, na forma in natura (tempo zero, as variedades Rosa e Espada apresentam os máximos teores de ácido ascórbico, porém o uso do branqueamento com vapor e o congelamento após 60 dias de armazenamento provocam perdas de, respectivamente, 53% ('Rosa' e 35% ('Espada'; 72% ('Rosa' e 60% ('Espada' destes compostos. No branqueamento por imersão em água, há perda completa do ácido ascórbico nas polpas das variedades Rosa e Espada. Em relação aos carotenoides totais, os valores foram semelhantes em polpas branqueadas a vapor e sem branqueamento no tempo zero,com tendência de redução durante o longo da armazenagem.

Full Text Available Carlos Drummond de Andrade, em A Rosa do Povo (1945 articula, por meio da palavra e da criação de um “eu” lírico habitante de um mundo em guerra, a construção de uma imagem, imbuída de teor histórico, do Brasil dos anos finais da 2ª guerra mundial. Os versos traduzem a experiência do Drummond gauche, angustiado pelos problemas do seu tempo, em que a individualidade advinda da fragmentação do homem moderno é marca do conflito entre o “eu” lírico e o mundo. O poeta descreve de forma melancólica a degeneração das coisas e dos homens, em meio à consciência paralisante e a falta de perspectivas. A força que emerge do símbolo da rosa respalda o acento poético do Itabirano: a destruição dos valores provocados pela morte e pelo derramar de sangue contrasta com o brotar da flor no asfalto.  Do chão forrado de cadáveres, emerge uma rosa, numa representação da resistência humana.

Barriers facing junior doctors in rural practice.

Smith, Deborah M

2005-01-01

Early postgraduate, or junior doctors, are still required to practise in rural and remote communities, and they continue to face numerous issues and difficulties. Within the hospital setting, exposure to rural practice appears to be very limited during internship, and also to some extent, during the second postgraduate year and beyond. This is a major issue for those required to undertake country relieving, rural terms or who will be bonded to rural and remote practice for several years after internship. This research investigated the current issues and difficulties faced by junior doctors, required to undertake rural and remote practice in Queensland, Australia. An exploratory study was undertaken. Primary data were collected through semi-structured interviews held with key stakeholders. Stakeholders included: directors of clinical training; medical educators; junior doctors; rural practitioners; academic rural practitioners; and medical administrators. Of the 23 people approached, a total of 19 agreed to be interviewed. The response rate was 82.6%. Similar to the issues identified in the literature, there are currently a number of barriers influencing the ability of junior doctors to practise competently and confidently when undertaking practice in rural and remote communities. Minimal clinical experience, lack of supervision and on-site support, inadequate orientation and uninformed expectations, limited access to relevant education, and the influence of isolation, results in an overall lack of preparation both professionally and personally. When asked, respondents supported the identification of core skills and knowledge, and integration of these and other issues affecting rural practice, into their hospital-based programs. Current hospital-based education and training programs were not adequately preparing junior doctors for rural and remote practice. It was commented that orientation and education, with a rural emphasis, could assist junior doctors in their

1980-01-01

The purpose of the ROSA-III experiment with a scaled BWR test facility is to examine primary coolant thermal-hydraulic behavior and performance of ECCS during a posturated loss-of-coolant accident of BWR. The results provide information for verification and improvement of reactor safety analysis codes. Run 702 assumed a 200% split break at the recirculation pump suction line under an average core power without ECCS activation. Post - test analysis of the Run 702 experiment was made with computer code RELAP4J. Agreement of the calculated system pressure and the experiment one was good. However, the calculated heater surface temperatures were higher than the measured ones. Also, the axial temperature distribution was different in tendency from the experimental one. From these results, the necessity was indicated of improving the analytical model of void distribution in the core and the nodalization in the pressure vassel, in order to make the analysis more realistic.

Standardised patients are used in medical education to expose students to clinical contexts and facilitate transition to clinical practice, and this approach is gaining momentum in physiotherapy programs. Expense and availability of trained standardised patients are factors limiting widespread adoption, and accessing clinical visits with real patients can be challenging. This study addressed these issues by engaging senior students as standardised patients for junior students. It evaluated how this approach impacted self-reported constructs of both the junior and senior students. Learning activities for undergraduate physiotherapy students were developed in five courses (Neurology, Cardiorespiratory and three Musculoskeletal courses) so that junior students (Year 2 and 3) could develop skills and confidence in patient interview, physical examination and patient management through their interaction with standardised patients played by senior students (Year 4). Surveys were administered before and after the interactions to record junior students' self-reported confidence, communication, preparedness for clinic, and insight into their abilities; and senior students' confidence and insight into what it is like to be a patient. Satisfaction regarding this learning approach was surveyed in both the junior and senior students. A total of 253 students completed the surveys (mean 92.5% response rate). Across all courses, junior students reported a significant (all P Senior students demonstrated a significant improvement in their confidence in providing feedback and insight into their own learning (P senior students as standardised patients resulted in positive experiences for both junior and senior students across a variety of physiotherapy areas, activities, and stages within a physiotherapy program. These findings support the engagement of senior students as standardised patients to enhance learning within physiotherapy programs, and may have application across other

Hibiscus rosa- sinensis is a biodegradable material that has remained untested for flocculating properties. The objective of this study is to examine the efficiency of coagulation-flocculation processes for the removal of color, iron (Fe3+), suspended solids, turbidity and ammonia nitrogen(NH3-N), from landfill leachate using 4,000 mg/L alum in conjunction with H. rosa- sinensis leaf extract (HBaqs). Hydroxyl (O-H) and (carboxyl) C=O functional groups along the HBaqs chain help to indulge flocculating efficiency of HBaqs via bridging. The experiments confirm the positive coagulation properties of HBaqs. The Fe3+ removal rate using 4,000 mg/L alum as sole coagulant was approximately 60 %, and increased to 100 % when 4,000 mg/L alum was mixed with 500 mg/L HBaqs. By mixing, 4,000 mg/L alum with 100-500 mg/L HBaqs, 72 % of SS was removed as compared with only 45 % reduction using 4,000 mg/L alum as sole coagulant.

Tasaka, Kanji; Suzuki, Mitsuhiro; Koizumi, Yasuo

1985-10-01

A common understanding and interpretation of BWR system response and the controlling phenomena in LOCA transients has been achieved through the evaluation and comparison of counterpart tests performed in the ROSA-III and FIST test facilities. These facilities, which are designed to simulate the thermal-hydraulic response of BWR systems, are operated respectively by the Japan Atomic Energy Research Institute (JAERI) and the General Electric Company. Comparison is made between three types of counterpart tests, each performed under similar tests conditions in the two facilities. They are large break, small break, and steamline break LOCA's. The system responses to these tests in each facility are quite similar. The sequence of events are similar, and the timing of these events are similar. Differences that do occur are due to minor differences in modeling objectives, facility scaling, and test conditions. Parallel channel flow interactions effects in the ROSA-III four channel (half length) core, although noticeable in the large break test, do not result in major differences with the single channel response in FIST. In the small break tests the timing of events is offset by the earlier ADS actuation in FIST. The steamline test responses are similar except there is no heatup in FIST, resulting from a different ECCS trip modeling. Overall comparisons between ROSA-III and FIST system responses in LOCA tests is very good. (author)

ROSA-II test data report, 13

International Nuclear Information System (INIS)

1978-07-01

Results of the ROSA-II test simulating a loss-of-coolant accident (LOCA) in a PWR are presented, including test conditions and interpretations of phenomena observed in test runs 502, 505, 506 and 507. Development tests were performed to find a more effective ECCS injection method than the existing one based on cold leg injection. A combined injection of hot water into upper plenum in early stage of blowdown and subsequent cold water into lower plenum is the most effective method for a cold leg break. A hot leg injection of a low pressure injection system is effective for direct core cooling and early reflooding. The generalization for actual reactors will require analyses with a reliable code.

Background The present study investigates the cardioprotective effects of Hibiscus rosa sinensis in myocardial ischemic reperfusion injury, particularly in terms of its antioxidant effects. Methods The medicinal values of the flowers of Hibiscus rosa sinensis (Chinese rose) have been mentioned in ancient literature as useful in disorders of the heart. Dried pulverized flower of Hibiscus rosa sinensis was administered orally to Wistar albino rats (150–200 gms) in three different doses [125, 250 and 500 mg/kg in 2% carboxy methyl cellulose (CMC)], 6 days per week for 4 weeks. Thereafter, rats were sacrificed; either for the determination of baseline changes in cardiac endogenous antioxidants [superoxide dismutase, reduced glutathione and catalase] or the hearts were subjected to isoproterenol induced myocardial necrosis. Results There was significant increase in the baseline contents of thiobarbituric acid reactive substances (TBARS) [a measure of lipid per oxidation] with both doses of Hibiscus Rosa sinensis. In the 250 mg/kg treated group, there was significant increase in superoxide dismutase, reduced glutathione, and catalase levels but not in the 125 and 500 mg/kg treated groups. Significant rise in myocardial thiobarbituric acid reactive substances and loss of superoxide dismutase, catalase and reduced glutathione (suggestive of increased oxidative stress) occurred in the vehicle treated hearts subjected to in vivo myocardial ischemic reperfusion injury. Conclusion It may be concluded that flower of Hibiscus rosa sinensis (250 mg/kg) augments endogenous antioxidant compounds of rat heart and also prevents the myocardium from isoproterenol induced myocardial injury.

Full Text Available A través de la Memoria Histórica, la Historia con mayúsculas se ha convertido en una fuente inagotable para narrar grandes historias con minúscula. De manera paralela, el paso de una cultura eminentemente letrada a otra más visual con predominio de la imagen ha favorecido la progresiva incorporación en el ámbito educativo de fuentes procedentes de la cultura popular, cuyos autores se aproximan al hecho histórico desde una perspectiva más íntima y reflexiva. En el presente artículo se fundamenta el potencial del álbum ilustrado como fórmula narrativa complementaria al manual escolar o libro de texto de Historia, especialmente en el tratamiento de temas complejos y delicados, como el holocausto nazi. Además, se propone un modelo de análisis que tiene en cuenta las particularidades de este género artístico en la construcción de la historiografía por medio de la incorporación de imágenes que van más allá de ser una redundancia o aclaración del texto. Para el cumplimiento de ambos objetivos, una vez analizado la concepción actual de la narración histórica, se estudia en detalle el álbum Rosa Blanca, contextualizado en la ocupación nazi durante la Segunda Guerra Mundial.

The rat is an important laboratory animal for physiological, toxicological and pharmacological studies. Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) is a simple and efficient tool to generate precise genetic modifications in rats, which will promote the accumulation of genetic resources and enable more precise studies of gene function. To monitor Cre-loxP-mediated excision in vivo, we generated a Cre reporter rat strain (Rosa26-imCherry) by knockin of a Cre reporter cassette at the Rosa26 locus using CRISPR/Cas9. Rosa26-imCherry rats exhibited inducible expression of the mCherry cassette (imCherry) using the Cre-loxP system, whereas normal rats exhibited ubiquitous expression of eGFP but not mCherry in the whole body. Injection of adeno-associated virus serotype 9-Cre into the hippocampus and skeletal muscle resulted in mCherry expression in virus-infected cells. Cre-loxP-mediated mCherry expression was then evaluated by crossing Rosa26-imCherry rats with transgenic rats ubiquitously expressing CAG-Cre, heart-specific α-MHC-Cre transgenic rats and liver-specific Alb-Cre knockin rats. Finally, using the established system the expression pattern of Cre driven by two endogenous gene promoters (Wfs1-Cre knockin rat, FabP2-Cre knockin rat) was traced. In summary, we demonstrated excision of the loxP-flanked allele in Rosa26-imCherry rats via activation of mCherry expression in the presence of Cre recombinase. This newly established Rosa26-imCherry rat strain represents a useful tool to facilitate Cre-expression pattern determination and tracing experiments. © 2017 Federation of European Biochemical Societies.

Has ADVANCE Affected Senior Compared to Junior Women Scientists Differently?

Science.gov (United States)

Rosser, Sue

2015-01-01

Substantial evidence exists to demonstrate that the NSF ADVANCE Inititiative has made a positive impact upon institutions. Since it began in 2001, ADVANCE has changed the conversation, policies, and practices in ways to remove obstacles and systemic barriers preventing success for academic women scientists and engineers. Results from ADVANCE projects on campuses have facilitated consensus nationally about policies and practices that institutions may implement to help to alleviate issues, particularly for junior women scientists.Although getting women into senior and leadership positions in STEM constituted an initial impetus for ADVANCE, less emphasis was placed upon the needs of senior women scientists. Surveys of academic women scientists indicate that the issues faced by junior and senior women scientists differ significantly. The focus of ADVANCE on junior women in many ways seemed appropriate--the senior cohort of women scinetists is fed by the junior cohort of scientists; senior women serve as mentors, role models, and leaders for the junior colleagues, while continuing to struggle to achieve full status in the profession. This presentation will center on the differences in issues faced by senior compared to junior women scientists to explore whether a next step for ADVANCE should be to address needs of senior academic women scientists.

Evaluating Junior Secondary Science Textbook Usage in Australian Schools

Science.gov (United States)

McDonald, Christine V.

2016-08-01

A large body of research has drawn attention to the importance of providing engaging learning experiences in junior secondary science classes, in an attempt to attract more students into post-compulsory science courses. The reality of time and resource constraints, and the high proportion of non-specialist science teachers teaching science, has resulted in an overreliance on more transmissive pedagogical tools, such as textbooks. This study sought to evaluate the usage of junior secondary science textbooks in Australian schools. Data were collected via surveys from 486 schools teaching junior secondary (years 7-10), representing all Australian states and territories. Results indicated that most Australian schools use a science textbook in the junior secondary years, and textbooks are used in the majority of science lessons. The most highly cited reason influencing choice of textbook was layout/colour/illustrations, and electronic technologies were found to be the dominant curricula material utilised, in addition to textbooks, in junior secondary science classes. Interestingly, the majority of respondents expressed high levels of satisfaction with their textbooks, although many were keen to stress the subsidiary role of textbooks in the classroom, emphasising the textbook was `one' component of their teaching repertoire. Importantly, respondents were also keen to stress the benefits of textbooks in supporting substitute teachers, beginning teachers, and non-specialist science teachers; in addition to facilitating continuity of programming and staff support in schools with high staff turnover. Implications from this study highlight the need for high quality textbooks to support teaching and learning in Australian junior secondary science classes.

The stratigraphic record in EEB begins with an upper Paleozoic basal siliciclastic sequence (Farallones Group, Devonian - Carboniferous), unconformably overlain by basal Cretaceous formations (Bata to the east, Santa Rosa - Ubala - Chivor to the west o the Quetame Massif). The Cretaceous marine ingression took place in a tectonically active basin since Triassic and Jurassic. This tectonic setting last until the end of earliest Cretaceous giving place to a thick sedimentary sequence made of the aforementioned basal units and the Lutitas de Macanal, Las Juntas, Fomeque and Une formations. Paleozoic basement highs normal fault bounded, restrict the Cretaceous sedimentation in the EEB zone, this is evidence especially for the basal Cretaceous units (Berriasian). In this way, to the east of Montecristo Anticline (overlaying Farallones Group) we found conglomerates (Bata Formation), instead to the west sedimentation was mainly lodolithic (Santa Rosa Formation, new litostratigraphic unit). Toward Ubala, overlaying Paleozoic basement (Farallones Anticline) rest a calcareous -Terrigenous set (Ubala Formation new litostratigraphic unit). In Chivor - Malacara area we found evaporitic sets with calcareous rocks (Chivor Formation, new litostratigraphic unit) overlaying Santa Rosa Formation. In Valanginian times the sea regionally drown the area of EEB and give rise to marine offshore conditions (Lutitas de Macanal Formation) with episodic events of gravity flows (El Figaro - Los Cedros members). During Hauterivian to Albian times the accumulation of a sandy - muddy sediments in tidal fats or deltaic systems give rise the record of Las Juntas -Une formations. Finally in Barremian early Albian times there are a siliciclastic - calcareous record of marine offshore environments (Fomeque Formation).

The aim of the study was to compare anthropometric and physical performance data of players who were selected for a Victorian elite junior U18 Australian rules football squad. Prior to the selection of the final training squad, 54 players were assessed using a battery of standard anthropometric and physical performance tests. Multivariate analysis (MANOVA) showed significant (pcharacteristics can be observed that discriminate between players selected and non-selected, and demonstrates the value of physical fitness testing within the talent identification process of junior (16-18 years) players for squad and/or team selection. Based on MANOVA results, the findings from this study suggest team selection appeared to be related to a generally higher performance across the range of tests. Further, age was not a confounding variable as players selected tended to be younger than those non-selected. These findings reflect the general consensus that, in state-based junior competition, there is evidence of promoting overall player development, selecting those who are generally able to fulfil a range of positions and selecting players on their potential.

This report presents the experimental results of BWR LOCA integral tests, RUNs 915 and 920, which are performed in the ROSA-III program simulating 2 % main recirculation line break LOCA tests with and without pressure control system operation. The ROSA-III test facility simulates a BWR system with volume scale of 1/424 and has four half-length electrically heated fuel bundles, two active recirculation loops, four types of ECCS's, and steam and feedwater systems. The report presents (1) the experimental results of 2 % small break LOCA phanomena in the ROSA-III system and (2) the effects of the pressure control system on the LOCA phenomena. The pressure control system contributed to (A) prevent bulk flashing in the early blowdown phase, (B) early closure of MSIV by L2 level trip, (C) early actuation of ADS by L1 level trip. However, the core thermal responses of the two tests were similar because of the similar mass inventory in PV after the ADS actuation in both tests. (author)

The CRISPR/Cas9 system is increasingly used for gene inactivation in mouse zygotes, but homology-directed mutagenesis and use of inbred embryos are less established. In particular, Rosa26 knock-in alleles for the insertion of transgenes in a genomic 'safe harbor' site, have not been produced. Here we applied CRISPR/Cas9 for the knock-in of 8-11 kb inserts into Rosa26 of C57BL/6 zygotes. We found that 10-20 % of live pups derived from microinjected zygotes were founder mutants, without apparent off-target effects, and up to 50 % knock-in embryos were recovered upon coinjection of Cas9 mRNA and protein. Using this approach, we established a new mouse line for the Cre/loxP-dependent expression of Cas9. Altogether, our protocols and resources support the fast and direct generation of new Rosa26 knock-in alleles and of Cas9-mediated in vivo gene editing in the widely used C57BL/6 inbred strain.

Successful coaching in race walking requires a thorough understanding of the biomechanical principles underlying this unique form of gait. The purpose of this study was to analyze elite male and female junior race walkers and identify key kinematic variables. Twenty junior men and 20 junior women were videoed as they competed over 10 km in the 8th European Cup Race Walking. Three-dimensional kinematic data were obtained using motion analysis software (SIMI, Munich). Step length and cadence were correlated with speed in both sexes, and greater step lengths were the kinematic reason for junior men's faster walking speeds. While cadence did not differ between junior men and junior women, there was a difference in proportion of step time spent in contact. There were some differences between genders for upper body joint angles (e.g., elbow) but there were few differences within lower limb joint angles. Although some technical aspects (e.g., pelvic and shoulder girdle rotation) appeared undeveloped, it was noteworthy that most athletes achieved full knee extension at initial contact in accordance with the rules. However, in many athletes flight times were evident that might present problems during the transition to the higher standards of senior competition. There was a large range of ability among both sexes and coaches are advised to ensure that technical development continues during the transition to senior competition.

Moretti Massimo

2016-06-01

Full Text Available Beach sands from the Rosa Marina locality (Adriatic coast, southern Italy were analysed mainly microscopically in order to trace the source areas of their lithoclastic and bioclastic components. The main cropping out sedimentary units were also studied with the objective to identify the potential source areas of lithoclasts. This allowed to establish how the various rock units contribute to the formation of beach sands. The analysis of the bioclastic components allows to estimate the actual role of organisms regarding the supply of this material to the beach. Identification of taxa that are present in the beach sands as shell fragments or other remains was carried out at the genus or family level. Ecological investigation of the same beach and the recognition of sub-environments (mainly distinguished on the basis of the nature of the substrate and of the water depth was the key topic that allowed to establish the actual source areas of bioclasts in the Rosa Marina beach sands. The sedimentological analysis (including a physical study of the beach and the calculation of some statistical parameters concerning the grain-size curves shows that the Rosa Marina beach is nowadays subject to erosion.

Ceratitis capitata (Wiedemann), Ceratitis rosa Karsch, and Ceratitis cosyra (Walker) are fruit fly species (Diptera: Tephritidae) of economic importance in South Africa. These pests cause direct damage to a number of commercially produced fruit and are of phytosanitary concern. A study was conducted to determine the distribution, relative abundance, and seasonal occurrence of the three species in different climatic regions of South Africa. The relative abundance and seasonal phenology of C. capitata and C. rosa were also compared between production areas and home gardens in Stellenbosch, Western Cape. Yellow bucket traps baited with Biolure were used to trap the flies over a 2-yr period in the different sampling areas. Different fruit types were sampled in Stellenbosch to determine fruit fly infestation. C. capitata was found to have a widespread distribution in South Africa, whereas C. rosa were absent from or only present in low numbers in the drier regions. C. cosyra was restricted to the North East and East coast, following a similar pattern to the distribution of marula, Sclerocarrya birrea, an important wild host. Fruit in home gardens provided a breeding ground for C. capitata and C. rosa and a source for infestation of orchards when fruit started to mature, highlighting the need for an area-wide strategy for the control of fruit flies.

Wastewater is an alternative to traditional sources of renewable irrigation water in agriculture, particularly in water-scarce regions. However, the possible risks due to heavy metals accumulation in plant tissues are often overlooked by producers. The present study aimed to identify heavy metals-induced structural modifications to roots of scented Rosa species that were irrigated with water of marginal quality. The chemical and mineral contents from the experimental irrigation canal water (control) and treated wastewater were below the limits recommended by the Pakistan Environmental Protection Agency (Pak-EPA) for medicinal plants. The experimentally untreated wastewater contained electrical conductivity (EC), chemical oxygen demand (COD), biological oxygen demand (BOD), and heavy metals (Co, Cu, Cd, Pb) that were above the recommended limits. The responses by wastewater-treated Rosa species (Rosa damascena, R. bourboniana, R. Gruss-an-Teplitz, and R. centifolia) were evaluated. The experimental data revealed that treated wastewater significantly increased the thickness of collenchyma (cortex and pith) and parenchyma tissues (vascular bundle, xylem, and phloem) of R. Gruss-an-Teplitz. Root dermal tissues (epidermis) of R. bourboniana also responded to treated wastewater. R. damascena and R. centifolia were the least affected species, under the experimental irrigation conditions. Collenchyma and dermal tissues were thicker in R. damascena and R. Gruss-an-Teplitz under untreated wastewater conditions. In parenchyma tissues, vascular bundles were thicker in R. damascena in untreated wastewater conditions, while the xylem and phloem of R. Gruss-an-Teplitz were thicker where treated wastewater was applied. In tissues other than the vascular bundle, the differences in anatomical metrics due to the experimental irrigation treatments were greater during the second year of the experiment than in the first year. The contents of metals other than chromium in the roots and

The Effect of Rosa Damascena Extract on Expression of Neurotrophic Factors in the CA1 Neurons of Adult Rat Hippocampus Following Ischemia

Full Text Available Ischemic stroke is an important cause of death and disability in the world. Brain ischemia causes damage to brain cell, and among brain neurons, pyramidal neurons of the hippocampal CA1 region are more susceptive to ischemic injury. Recent findings suggest that neurotrophic factors protect against ischemic cell death. A dietary component of Rosa damascene extract possibly is associated with expression of neurotrophic factors mRNA following ischemia, so it can have therapeutic effect on cerebral ischemia. The present study attempts to evaluate the neuroprotective effect of Rosa damascene extract on adult rat hippocampal neurons following ischemic brain injury. Forty-eight adult male Wistar rats (weighing 250±20 gr and ages 10-12 weeks used in this study, animals randomly were divided into 6 groups including Control, ischemia/ reperfusion (IR, vehicle and three treated groups (IR+0.5, 1, 2 mg/ml extract. Global ischemia was induced by bilateral common carotid arteries occlusion for 20 minutes. The treatment was done by different doses of Rosa damascena extract for 30 days. After 30 days cell death and gene expression in neurons of the CA1 region of the hippocampus were evaluated by Nissl staining and real time PCR assay. We found a significant decrease in NGF, BDNF and NT3 mRNA expression in neurons of CA1 region of the hippocampus in ischemia group compared to control group (P<0.0001. Our results also revealed that the number of dark neurons significantly increases in ischemia group compared to control group (P<0.0001. Following treatment with Rosa damascene extract reduced the number of dark neurons that was associated with NGF, NT3, and BDNF mRNA expression. All doses level had positive effects, but the most effective dose of Rosa damascena extract was 1 mg/ml. Our results suggest that neuroprotective activity of Rosa damascena can enhance hippocampal CA1 neuronal survival after global ischemia.

The postcoital antifertility properties of benzene hot extracts of Hibiscus rosa sinensis flowers, leaves, and stembarks, collected during the winter, spring, rainy, and summer seasons, were investigated in female rats. Only extracts from the flowers of the plant were 100% effective in preventing pregnancy. Those flowers collected during the winter showed the greatest potency, followed by those collected in the spring, rainy season, and summer, in decreasing order. Benzene extracts of flowers collected from Hibiscus mutabilis, Hibiscus schizopetalus, and Malvasicus grandiflorus, plants resembling Hibiscus rosa sinensis in petaloid structure, did not markedly affect pregnancy.

ROSA-II test data report, 10

International Nuclear Information System (INIS)

1977-12-01

Results of the ROSA-II test simulating a loss-of coolant accident (LOCA) in a light water reactor (LWR) are presented, including the test conditions and interpretation of the phenomena for test runs 415, 417, 421 and 422. Even in small break at the cold leg, the core is exposed to void and the temperature rises. In small break of the hot leg, however, core cooling keeps without temperature rise, because there still remains much residual water and upward core flow exists. Direct effect of the HPCI on the depressurization rate is small, but it increases the accumulator injection rate, leading to early core reflooding and early core cooling from upward. Effects of the secondary system depressurization are increase of depressurization and discharge rates of the primary loop, which results in early initiation of the accumulator injection and core reflooding.

Western Imperialism Against Primitive Communism. A New Reading of Rosa Luxemburg’s Economic Writings

Directory of Open Access Journals (Sweden)

Michael Löwy

2012-01-01

Full Text Available The discussion on Rosa Luxemburg’s theories of imperialism hasmainly focused on the economic argument - the schemes of reproduction, theprocess of circulation, the need for “external” markets, etc. There is howeveranother dimension, at least as important : the struggle of imperialism againstpre-capitalist economies, the ruthless destruction of “natural” and peasant economies,many of them being forms of primitive communism. Luxemburg’sinterest for primitive communist societies is documented by her Introductionto Political Economy and the imperialist war against them is discussed both inthis work and in the last chapters of The Accumulation of Capital. A whollyoriginal approach to the evolution of social formations, running counter tolinear “progressive” views of bourgeois ideology, is outlined in these reflections. Present indigenous struggles e.g. in Latin America, against multinational oil or mining companies, illustrate the topicality of Rosa Luxemburg’s argument in the 21th century.

Junior doctors are exposed to multiple occupational risks. The aim of this study was to assess the risk factors and protective factors for mood and anxiety disorders among junior doctors. We conducted a cross-sectional study via an anonymous online questionnaire between October 2011 and June 2012. All the junior doctors in our faculty were included. The questionnaire inquired about demographic and health data. It contained four validated scales: the Center for Epidemiologic Studies Depression Scale (CES-D), the Spielberger anxiety questionnaire, the WHO quality of life (WHO - QOL) questionnaire and the Job Content Questionnaire. Finally, it sought to clarify the conditions of professional practice and the interactions between university programmes and junior doctorate students (change of specialty, pregnancy, leave of absence, etc.). 192 juniors doctors participated in the study, 68.2% of whom were women. Out of the group, 13.0% presented a depressive syndrome, while 28.7% presented an anxiety disorder, 32.8% were experiencing Job Strain and 29.7% Iso Strain. The risk factor for anxiety was competition between junior doctors: OR=4.23 (1.06 ‒ 16.82). The protective factors for mood disorders were the help provided by senior physicians and the respect shown by patients: OR=0.21 (0.06-0.74) and 0.20 (0.06-0.75), respectively. This study demonstrated the impact of the relationships with senior physicians and patients on junior doctors' health at work. Consequently, prevention should not be focused uniquely on work organization, but should increase physicians' awareness of the importance of this relationship.

Full Text Available La edición de Cátedra de La guaracha del Macho Camacho (2000 de Luis R. Sánchez lleva en su portada una reproducción incompleta de un llamativo cartel del artista puertorriqueño José Rosa. Esta obra, un iconotexto que estudiamos y reproducimos íntegramente, incorpora una rica serie de citas –falsas y verdaderas– de La guaracha. Proponemos un recorrido interpretativo de la configuración visual y textual de esta imagen, creada con otro fin que el de servir de pórtico a la novela. Con ella Rosa condensaba ya en 1977 de manera sorprendente muchos de los enfoques que los críticos literarios de Sánchez sólo desarrollarían mucho más tarde: la desacralización, el enmascaramiento racial, sexual y social, la dictadura del ocio y del consumo, el barroquismo...

The Santa Fe Alliance for Science (SFAFS) was founded in May, 2005. SFAFS exists to provide assistance in K-14 math and science education in the greater Santa Fe area. It does this via extensive programs (1) in math and science tutoring at Santa Fe High School, Santa Fe Community College and to a lesser degree at other schools, (2) science fair advising and judging, (3) its ``Santa Fe Science Cafe for Young Thinkers'' series, (4) a program of professional enrichment for K-12 math and science teachers, and (5) a fledging math intervention program in middle school math. Well over 150 STEM professionals, working mostly as volunteers, have contributed since our beginning. Participation by students, parents and teachers has increased dramatically over the years, leading to much more positive views of math and science, especially among elementary school students and teachers. Support from the community and from local school districts has been very strong. I will present a brief status report on SFAFS activities, discuss some of the lessons learned along the way and describe briefly some ideas for the future. More information can be found at the SFAFS website, www.sfafs.org.

MARILUZ AYALA-VÁSQUEZ

2008-01-01

Full Text Available El mildeo velloso de la rosa es la enfermedad más limitante de este cultivo en Colombia. Aunque algunos trabajos de investigación se han adelantado recientemente sobre la epidemiología de esta enfermedad, uno de los campos menos estudiados es el nivel de variabilidad de su agente causal. El conocimiento de este aspecto es fundamental para definir las estrategias de manejo, especialmente aquellas relacionadas con la resistencia genética y el control químico. Los objetivos de esta investigación fueron confirmar la identidad taxonómica del agente causal del mildeo velloso de la rosa y profundizar en el conocimiento de su estructura poblacional en Colombia. Para esto se colectaron 34 aislamientos del pseudohongo en cultivos de rosas ubicados en Antioquia y la sabana de Bogotá y se extrajo su ADN, para proceder a la amplificación mediante PCR de la región ITS del ADNr utilizando los primers especieespecíficos PS3 y PS1. Dichos productos se emplearon tanto para su secuenciación directa como para la evaluación de variabilidad genética mediante la técnica PCRRFLP, resultados que se complementaron con la utilización de los marcadores RAPD y RAMS. La presencia de un amplicón de aproximadamente 700 pb que compartió un porcentaje de identidad del 100% con secuencias depositadas en el GenBank, permitió confirmar a los aislamientos como pertenecientes a Peronospora sparsa, mientras que el análisis de RFLP, RAPD y RAMS indicó un muy bajo nivel de variabilidad entre todos los aislamientos, concluyéndose que la población de P. sparsa en Colombia es predominantemente clonal

Estimate the burden of disease from Salmonella spp. and Shigella spp. in four departments of Guatemala in 2010. Burden of disease study based on document analysis of published population surveys, laboratory files, and surveillance data from the Health Management Information System (SIGSA) in four departments of Guatemala: Huehuetenango, Jutiapa, Quetzaltenango, and Santa Rosa, in 2010. Information was supplemented by a laboratory survey. Burden of disease was estimated using methodology adapted by the World Health Organization from the United States Centers for Disease Control and Prevention. Surveillance data yielded 72 salmonellosis and 172 shigellosis cases. According to population surveys, the percentage of the population that consults health services for diarrhea is 64.7% (95% CI: 60.6%-68.7%) in Quetzaltenango and 61.0% (95% CI: 56.0%-66.0%) in Santa Rosa. In the 115 laboratories that answered the survey (72.8% response rate), 6 051 suspected samples were collected for stool culture and 3 290 for hemoculture; 39.4% and 100.0% of them were processed, respectively. In all, 85 Salmonella spp. and 113 Shigella spp. strains were isolated. For each reported case of salmonellosis and shigellosis, it was estimated that 40 cases are not reported in Quetzaltenango, 55 in Huehuetenango, 345 in Santa Rosa, and 466 in Jutiapa. Estimated burden of disease ranged from 5 to 2 230 cases per 100 000 population for salmonellosis and from 60 to 1 195 cases per 100 000 population for shigellosis. Salmonellosis and shigellosis are a major public health problem in the departments studied and in Guatemala. Burden of disease from these pathogens is higher than that reported by SIGSA.

Head Impact Exposure in Junior and Adult Australian Football Players

Directory of Open Access Journals (Sweden)

Mark Hecimovich

2018-01-01

Full Text Available This study measured and compared the frequency, magnitude, and distribution of head impacts sustained by junior and adult Australian football players, respectively, and between player positions over a season of games. Twelve junior and twelve adult players were tracked using a skin-mounted impact sensor. Head impact exposure, including frequency, magnitude, and location of impacts, was quantified using previously established methods. Over the collection period, there were no significant differences in the impact frequency between junior and adult players. However, there was a significant increase in the frequency of head impacts for midfielders in both grades once we accounted for player position. A comparable amount of head impacts in both junior and adult players has implications for Australian football regarding player safety and medical coverage as younger players sustained similar impact levels as adult players. The other implication of a higher impact profile within midfielders is that, by targeting education and prevention strategies, a decrease in the incidence of sports-related concussion may result.

Research Resources Survey: Radiology Junior Faculty Development.

Krupinski, Elizabeth A; Votaw, John R

2015-07-01

To assess resources available to junior faculty in US academic radiology departments for research mentorship and funding opportunities and to determine if certain resources are more common in successful programs. An anonymous survey covering scientific environment and research mentorship and was sent to vice-chairs of research of radiology departments. Results were evaluated to identify practices of research programs with respect to mentorship, resources, and opportunities. Academy of Radiology Research's 2012 National Institutes of Health (NIH) grants and awards list was used to determine if environment and practices correlate with funding. There was a 51% response rate. A greater fraction of clinical faculty gets promoted from assistant to associate professor than research faculty. Research faculty overall submits more funding applications. Most programs support start-up costs and K-awards. Over half of the departments have a vice-chair for faculty development, and most have formal mentorship programs. Faculty members are expected to teach, engage in service, publish, and apply for and get research funding within 3 years of hire. Top-tier programs as judged by NIH awards have a combination of MDs who devote >50% effort to research and PhD faculty. Key factors holding back both clinical and research junior faculty development were motivation, resources, and time, although programs reported high availability of resources and support at the department level. Better marketing of resources for junior faculty, effort devoted to mentoring clinical faculty in research, and explicit milestones/expectations for achievement could enhance junior faculty success, promote interest in the clinician–scientist career path for radiologists, and lead to greater research success.

Bullying and harassment – Are junior doctors always the victims?

International Nuclear Information System (INIS)

Nyhsen, C.M.; Patel, P.; O'Connell, J.E.

2016-01-01

Introduction: NHS staff have the right to work in an environment free from bullying, harassment and violence. There should be good team-working with colleagues from all disciplines. Reports of bullying experienced by junior doctors resulted in mandatory annual GMC surveys regarding the quality of training. This led to medical trainees being surveyed more than any other staff. Radiographers informally reported bullying and harassment (B&H) incidents involving trainees. This survey aims to quantify the issue. Methods: Online survey of general and CT radiographers at a large acute hospital in the North East of England addressing incidents involving junior doctors and occurring in the preceding 12 months. Results: The survey was completed by 86% (44/51) general and 5/7 CT radiographers. Overall 45% experienced bullying, 92% had their own/witnessed a colleague's opinion being ignored and 57% were the target of loud verbal abuse/anger or witnessed colleagues being treated in that way. Several radiographers reported 5 or more B&H incidents. 26 radiographers (51%) were shouted at/ridiculed in theatre, 4 feeling unsafe/physically threatened. Junior doctors regularly queried the need to supervise CT contrast injections on call. Free text comments highlighted that doctors rarely introduced themselves to radiology staff. Conclusion: Radiographers report significant incidents of B&H involving junior doctors, who do not always seem to appreciate radiation exposure legislation, patient safety protocols or respect the seniority of highly trained radiographers. Measures introduced subsequently include guidance for radiographers, a dedicated radiology e-learning package for trainees and classroom sessions for foundation doctors and final year undergraduate students. - Highlights: • Bullying and harassment of radiographers is a persistent problem. • Some radiographers reported feeling physically threatened in theatre. • Some junior doctors do not respect radiation exposure

Currently in the literature, there is a dearth of empirical research that confirms whether international junior success is a reliable predictor for future international senior success. Despite the uncertainty of the junior-senior relationship, federations and coaches still tend to use junior success as a predictor for long-term senior success. A range of former investigations utilising a retrospective lens has merely focused on success that athletes attained at junior level competitions. Success that was achieved at senior-level competitions but at a junior age was relatively ignored. This study explored to what extent international senior success can be predicted based on success that athletes achieved in either international junior level competitions (i.e. junior medalists) or senior competitions at a junior age (i.e. early achievers). The sample contains 4011 international male and female athletes from three combat sports (taekwondo, wrestling and boxing), who were born between 1974 and 1990 and participated in both international junior and senior-level competitions between 1990 and 2016. Gender and sport differences were compared. The results revealed that 61.4% of the junior medalists and 90.4% of the early achievers went on to win international medals at a senior age. Among the early achievers, 92.2% of the taekwondo athletes, 68.4% of the wrestling athletes and 37.9% of the boxing athletes could be reliably "predicted" to win international senior medals. The findings demonstrate that specific to the three combat sports examined, international junior success appears to be an important predictor to long-term international senior success.

The rose aphid, Macrosiphum rosae (L.), is one of the most important pests on rose plants (Rosa spp.) with a worldwide distribution. As resistance indices, the development, survivorship, and reproduction of this aphid were evaluated on 10 rose cultivars, including Bella Vita, Cool Water, Dolce Vita, Maroussia, Orange Juice, Pinkpromise, Roulette, Tea, Valentine, and Persian Yellow in laboratory at 25 ± 1°C, 65 ± 5% relative humidity, and photoperiod of 16:8 (L/D) h. Rose aphid successfully survived on all 10 rose cultivars, although mortality rate was higher on Tea and Bella Vita. The number of offspring per female differed significantly among the tested rose cultivars, and ranged from 9.2 on Tea to 38.7 nymphs on Orange Juice. Population growth parameters were significantly affected by rose cultivars. The longest mean generation time (T) was observed on Bella Vita (14.8 days) and Tea (14.7 days) and the shortest on Orange Juice (10.0 days). The net reproductive rate (R 0 ) ranged from 6.9 on Tea to 33.2 nymphs on Orange Juice cultivar. Correspondingly, the highest value of intrinsic rate of increase (r m ) was observed on Orange Juice (0.348 day -1 ) and lower values on Tea (0.131 day -1 ) followed by Bella Vita (0.154 day -1 ). Cluster analysis of all the measured parameters of rose aphid on different rose cultivars revealed that Tea and Bella Vita were relatively resistant to M. rosae. These findings could be useful in developing an integrated pest management (IPM) program for this aphid in urbanized areas and commercial rose potting.

The rose (Rosa sp.) petals can be dried after 2 days at about 30degC reaching an equilibrium moisture content after 16 h using the solar wire basket dryer. The initial moisture content (wet wt basis) and final moisture content (dry wt basis), determined by the Dean-Stark toluene were 65.7 and 25.2% respectively. The intensity of the rose red coloured pigment (pelargonidin) decreased by a factor of 2.5 after drying. The pelargonidin ethanoic extract as an acid-base indicator, has a K{sub 4} value of 1 x 10{sup -4} mol 1{sup -1} and pH of end point 4 and imbibed on filter paper and allowed to air dry for 5 min showed excellent properties as acid-based test tapes.

The purpose of the ROSA-III experiment with a scaled BWR test facility is to examine primary coolant thermalhydraulic behavior and performance during a postulated loss-of-coolant accident of BWR. The results provide information for verification and improvement of reactor safety analysis codes. Run 702 assumes a recirculation line double ended break at the pump suction with average core power and no ECCS. Prediction of the Run 702 experiment was made with computer code RELAP-4J. What determine the coolant behavior are mixture level in the downcomer and flowrates and flow directions at jet pump drive flow nozzle, jet pump suction and discharge. There is thus the need for these measurements to compare predicted results with experimental ones. The liquid level formation model also needs improvement. (author)

To describe the process of approval and implementation of a comprehensive smoke-free law in the province of Santa Fe, Argentina, between 2005 and 2009. Review of the Santa Fe smoke-free legislation, articles published in local newspapers and documentation on two lawsuits filed against the law, and interviews with key individuals in Santa Fe. Efforts to implement smoke-free policies in Santa Fe began during the 1990s without success, and resumed in 2005 when the provincial Legislature approved the first 100% smoke-free subnational law in Argentina. There was no strong opposition during the discussions within the legislature. As in other parts of the world, pro-tobacco industry interests attempted to block the implementation of the law using well known strategies. These efforts included a controversy media campaign set up, the creation of a hospitality industry association and a virtual smokers' rights group, the introduction of a counterproposal seeking modification of the law, the challenge of the law in the Supreme Court, and the proposal of a weak national bill that would 'conflict' with the subnational law. Tobacco control advocates sought media attention as a strategy to protect the law. Santa Fe is the first subnational jurisdiction in Latin America to have enacted a comprehensive smoke-free policy following the recommendations of the World Health Organization (WHO) Framework Convention on Tobacco Control. After 3 years of implementation, pro-tobacco industry forces failed to undermine the law. Other subnational jurisdictions in Argentina, as well as in Mexico and Brazil are following the Santa Fe example.

Perceived Injury Risk among Junior Cricketers: A Cross Sectional Survey

Directory of Open Access Journals (Sweden)

Prasanna J. Gamage

2017-08-01

Full Text Available Understanding how junior athletes perceive injury risks when participating in sport and the environment they play in is an important component of injury prevention. This study investigates how Sri Lankan junior cricketers (n = 365, aged 11–14 years, boys perceive injury risks associated with playing cricket. The study used a Sri Lankan modification of an Australian junior cricket injury risk perception survey that considered playing cricket versus other sports, different cricket playing positions and roles, and different ground conditions. The risk of playing cricket was considered to be greater than that for cycling, but lower than that for rugby and soccer. Fast-bowlers, batters facing fast-bowlers, fielding close in the field, and wicket-keeping without a helmet were perceived to pose greater risks of injury than other scenarios. Playing on hard, bumpy and/or wet ground conditions were perceived to have a high risk opposed to playing on a grass field. Fielding in the outfield and wicket-keeping to fast-bowlers whilst wearing a helmet were perceived as low risk actions. The risk perceptions of junior cricketers identified in this study, do not necessarily reflect the true injury risk in some instances. This information will inform the development of injury prevention education interventions to address these risk perceptions in junior cricketers.

Santa Elena. Ready to reshape its transport energy matrix

2012-07-01

The renewable energy issue opens the door to an ambient of opportunities. Santa Elena, one of the coastal provinces of Ecuador has the chance to go from a fossil fuel energy culture to a new energy scheme based on the use of environmental friendly fuels like natural gas and other renewable energy carriers like hydrogen. The marginal production of oil and natural gas from the Gustavo Galindo Velasco field and the updated gas reserves from the Gulf of Guayaquil make it possible. Infrastructure for natural gas production and distribution for vehicles is almost ready and any of the three refineries can generate hydrogen from natural gas. This provides the opportunity to reshape the Santa Elena transport energy matrix, where vehicles can burn natural gas and inter country buses can work with hydrogen. Traditional Fishing boats can be fitted with hydrogen storage and fuel systems later on. Santa Elena should face this challenge through a joint effort of public and private parties. Santa Elena State University and its partners as a focus point to create: The Campus of Energy Knowledge, where research, science and technology will serve companies that work in the energy business with a strong synergy, which will create jobs for the Santa Elena people.

Experimental analysis of the power curve sensitivity test series at ROSA-III

International Nuclear Information System (INIS)

Koizumi, Y.; Iriko, M.; Yonomoto, T.; Tasaka, K.

1985-01-01

The rig of safety assessment (ROSA)-III facility is a volumetrically scaled (1/424) boiling water reactor (BWR/6) system with an electrically heated core designed for integral LOCA and ECCS tests. Seven recirculation pump suction line break LOCA experiments were conducted at the ROSA-III facility in order to examine the effect of the initial stored heat of a fuel rod on the peak cladding temperature (PCT). The break size was changed from 200% to 5% in the test series and a failure of a high pressure core spray (HPCS) diesel generator was assumed. Three power curves which represented conservative, realistic and zero initial stored heat, respectively, were used. In a large break LOCA such as 200% or 50% breaks, the initial stored heat in a fuel rod has a large effect on the cladding surface temperature because core uncovery occurs before all the initial stored heat is released, whereas in a small break LOCA such as a 5% break little effect is observed because core uncovery occurs after the initial stored heat is released. The maximum PCTs for the conservative initial stored heat case was 925 K, obtained in the 50% break experiment, and that for the realistic initial stored heat case was 835 K, obtained in the 5% break experiment.

2011-12-01

Mentoring in academic medicine has been shown to contribute to the success of junior faculty, resulting in increased productivity, career satisfaction, and opportunities for networking. Although traditional dyadic mentoring, involving one senior faculty member and one junior protégé, is the dominant model for mentoring in the academic environment, there is increasing recognition that the sharing of knowledge, skills, and experiences among peers may also contribute to the career development of junior faculty. The authors describe the structure, activities, and outcomes of the Junior Faculty Laboratory (JFL), a self-organized, flexible, and dynamic peer-mentoring model within the Duke University Center for the Study of Aging and Human Development. As an innovative mentoring model, JFL is entirely peer driven, and its activities are determined by the real-time needs of members. In contrast to some other peer-mentoring models, JFL lacks senior faculty input or a structured curriculum, members are multidisciplinary, meeting times are project driven rather than preset, and participation in collaborative projects is optional based on the interests and needs of group members. Additionally, JFL was not formed as a substitute for, but as a complement to, the dyadic mentoring relationships enjoyed by its members. The model, now in its fifth year, has demonstrated success and sustainability. The authors present the JFL as an innovative, mentoring model that can be reproduced by other junior faculty seeking to foster collegial relationships with peers while simultaneously enhancing their career development.

2017-09-27

The proportion of junior doctors required to complete psychiatry placements in the UK has increased, due in part to vacant training posts and psychiatry career workforce shortages, as can be seen across the world. The aim of this study was to understand the lived experience of a Foundation Year 1 junior doctor psychiatry placement and to understand how job components influence attitudes. The study was conducted using a cross-sectional qualitative phenomenological approach. Hospital and community psychiatry department settings in the North East of England, UK. In total, 14 Foundation Year 1 junior doctors were interviewed including seven men and seven women aged between 23 and 34 years. The majority had completed their medical degree in the UK and were White British. The lived experience of a junior doctor psychiatry placement was understood by three core themes: exposure to patient recovery, connectedness with others in the healthcare team and subjective interpretations of psychiatry. The experiences were moderated by instances of role definition, reaction to the specialty and the organisational fit of the junior doctor capacity in the specialty. The study reinforces and adds to the literature by identifying connectedness as being important for both job satisfaction and morale, which is currently damaged within the junior doctor population. The study provides in-depth insights into the lived experience of psychiatry placements and can be taken forward by educationalists to ensure the placements are meaningful experiences for junior doctors by developing role definition, belonging, structure and psychiatric care responsibility. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Dempsey, GM, Gibson, NV, Sykes, D, Pryjmachuk, BC, and Turner, AP. Match demands of senior and junior players during International Rugby League. J Strength Cond Res 32(6): 1678-1684, 2018-This study aims to quantify and compare the positional game demands of international junior and senior rugby league competition for the first time. Global positioning system (GPS) and video analysis were used to track 118 elite male rugby league players (57 seniors aged 28.7 ± 4.4 years; 61 juniors aged 17.2 ± 0.5 years) over 10 international matches (6 senior; 4 junior) characterized as either forwards (n = 67) or backs (n = 51). There were significant increases in the offensive carries (0.18 cf. 0.09 n·min; r = 0.56) and defensive tackles (0.36 cf. 0.23 n·min; r = 0.3) between senior and junior players, and forwards and backs (0.16 cf. 0.09; r = 0.34 and 0.41 cf. 0.14; r = 0.52), respectively. Running demands were significantly greater in backs than forwards (independent of playing level) for total distance (6,962 ± 1,263 m cf. 4,879 ± 1,824 m; r = 0.55), individualized high-speed distances (310 ± 158 m cf. 250 ± 171 m; r = 0.2), high-intensity accelerations (28.7 ± 12.1 m·s cf. 21.9 ± 11.7 m·s; r = 0.27), and decelerations (57.2 ± 18.3 m·s cf. 43.0 ± 17.8 m·s; r = 0.38). Positional differences were eliminated when reported relative to minutes played. From a practical perspective, although running demands relative to time on the pitch may prepare junior players for senior competition, it is not representative of the increased body mass and contact frequency within the senior game. Coaches should therefore reflect these differences within their physical preparation programs to prepare junior athletes accordingly for progression to the senior level.

Full Text Available This article concerns João Guimarães Rosa’s translation of the condensed novel Last of the Curlews (1954, from Canadian writer Fred Bodsworth, entitled O Último dos Maçaricos (1958. In the first place, we describe the context in which the translation was made as well as certain aspects of the process itself, such as the motivation behind it and the use of ornithological books by the translator. Then, some passages of the novel are analyzed in order to corroborate the conceivable effort undertaken by Rosa to write a poetically relevant text, even though the style of the novel does not match that of Rosa’s own oeuvre. Other texts besides the novel are used to achieve these objectives, such as documents, statements from close friends and the correspondence between Rosa and his Italian and German translators.

Full Text Available Ralstonia pseudosolanacearum (Ralstonia solanacearum phylotype I isolates found in stunted, yellowing, and wilted ornamental rose (Rosa spp. were assessed for their pathogenic ability in two rose cultivars (cv. “Armando” and cv. “Red Naomi” and in four solanaceous crops: tomato (Solanum lycopersicum cv. “Money Maker”, tobacco (Nicotiana tabacum cv. “White Burley”, eggplant (Solanum melongena cv. “Black Beauty” and sweet pepper (Capsicum annum cv. “Yolo Wonder”. Significant differences were observed in susceptibility between the two rose cultivars as well as between the two modes of inoculation performed. The cultivar “Armando” was significantly more susceptible than cultivar “Red Naomi,” exhibiting higher disease severity and incidence. Similarly, stem inoculation after wounding was found to be significantly more effective than soil drenching, resulting in higher disease severity. Additionally, a temperature dependency in susceptibility was observed for both cultivars irrespective of the mode of inoculation, however, this was significantly more pronounced upon soil drenching. The solanaceous crops all showed to be susceptible to the R. pseudosolanacearum isolates originated from the Rosa spp. plants. Furthermore, both rose cultivars were able to harbor symptomless infections with other R. pseudosolanacearum and R. solanacearum isolates than those isolated from rose. Our results clearly demonstrated that latent infections in a rose cultivar such as cv. “Red Naomi” do occur even at temperatures as low as 20°C. This latency poses high risks for the entire floricultural industry as latently infected Rosa spp. plants are propagated and distributed over various continents, including areas where climatic conditions are optimal for the pathogen.

To discover the level of interest in a surgical career amongst junior doctors and trainee interns in the Auckland region. Secondary aims are to identify the factors that influence career choice as well as the timing of career choice. An anonymous and structured questionnaire was distributed to all trainee interns and junior doctors in their first to fifth postgraduate years in the Auckland region. Questions were based on basic demographics, level of training, career preference and factors from previous experiences in surgery that may have influenced their career choice. Total of 87 replies with 36% expressed interest in surgery whereas 64% were interested in non-surgical specialties. Top three factors influencing career choice were similar in both groups: Lifestyle, career ambitions and family. Personal interest, practical hands-on and positive previous experiences were the top reasons why junior doctors chose surgery. Poor lifestyle, lacking of interest, limited future part-time work and previous negative experiences were the top reasons why junior doctors did not choose surgery. A significantly (pcareers earlier. Career aspirations of New Zealand junior doctors were similar to findings reported overseas. To promote surgery amongst junior doctors and medical students, attention should be paid to the key factors which may influence career choice. By improving working conditions and have better surgical education with good mentoring, team atmosphere and opportunities for early exposure will hopefully allow better recruitment and training of future surgeons.

In 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP), designed to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats, and geology within the 3-nautical-mile limit of California’s State Waters. The CSMP approach is to create highly detailed seafloor maps through collection, integration, interpretation, and visualization of swath sonar data, acoustic backscatter, seafloor video, seafloor photography, high-resolution seismic-reflection profiles, and bottom-sediment sampling data. The map products display seafloor morphology and character, identify potential marine benthic habitats, and illustrate both the surficial seafloor geology and shallow (to about 100 m) subsurface geology. The Offshore of Santa Barbara map area lies within the central Santa Barbara Channel region of the Southern California Bight. This geologically complex region forms a major biogeographic transition zone, separating the cold-temperate Oregonian province north of Point Conception from the warm-temperate California province to the south. The map area is in the southern part of the Western Transverse Ranges geologic province, which is north of the California Continental Borderland. Significant clockwise rotation—at least 90°—since the early Miocene has been proposed for the Western Transverse Ranges province, and geodetic studies indicate that the region is presently undergoing north-south shortening. Uplift rates (as much as 2.2 mm/yr) that are based on studies of onland marine terraces provide further evidence of significant shortening. The city of Santa Barbara, the main coastal population center in the map area, is part of a contiguous urban area that extends from Carpinteria to Goleta. This urban area was developed on the coalescing alluvial surfaces, uplifted marine terraces, and low hills that lie south of the east-west-trending Santa Ynez Mountains.

Little recent published evidence explores the relationship between academic performance in medical school and performance as a junior doctor. Although many forms of assessment are used to demonstrate a medical student's knowledge or competence, these measures may not reliably predict performance in clinical practice following graduation. This descriptive cohort study explores the relationship between academic performance of medical students and workplace performance as junior doctors, including the influence of age, gender, ethnicity, clinical attachment, assessment type and summary score measures (grade point average) on performance in the workplace as measured by the Junior Doctor Assessment Tool. There were two hundred participants. There were significant correlations between performance as a Junior Doctor (combined overall score) and the grade point average (r = 0.229, P = 0.002), the score from the Year 6 Emergency Medicine attachment (r = 0.361, P gender or ethnicity on the overall combined score of performance of the junior doctor. Performance on integrated assessments from medical school is correlated to performance as a practicing physician as measured by the Junior Doctor Assessment Tool. These findings support the value of combining undergraduate assessment scores to assess competence and predict future performance.

Sediment Dynamics Affecting the Threatened Santa Ana Sucker in the Highly-modified Santa Ana River and Inset Channel, Southern California, USA

Minear, J. T.; Wright, S. A.

In this study, we investigate the sediment dynamics of the low-flow channel of the Santa Ana River that is formed by wastewater discharges and contains some of the last remaining habitat of the Santa Ana Sucker (Catostomus santaanae). The Santa Ana River is a highly-modified river draining the San Bernardino Mountains and Inland Empire metropolitan area east of Los Angeles. Home to over 4 million people, the watershed provides habitat for the federally-threatened Santa Ana Sucker, which presently reside within the mainstem Santa Ana River in a reach supported by year-round constant discharges from water treatment plants. The nearly constant low-flow wastewater discharges and infrequent runoff events create a small, approximately 8 m wide, inset channel within the approximately 300 m wide mainstem channel that is typically dry except for large flood flows. The sediment dynamics within the inset channel are characterized by constantly evolving bed substrate and sediment transport rates, and occasional channel avulsions. The sediment dynamics have large influence on the Sucker, which rely on coarse-substrate (gravel and cobble) for their food production. In WY 2013 through the present, we investigated the sediment dynamics of the inset channel using repeat bathymetric and substrate surveys, bedload sampling, and discharge measurements. We found two distinct phases of the inset channel behavior: 1. 'Reset' flows, where sediment-laden mainstem discharges from upstream runoff events result in sand deposition in the inset channel or avulse the inset channel onto previously dry riverbed; and 2. 'Winnowing' flows, whereby the sand within the inset channel is removed by clear-water low flows from the wastewater treatment plant discharges. Thus, in contrast to many regulated rivers where high flows are required to flush fine sediments from the bed (for example, downstream from dams), in the Santa Ana River the low flows from wastewater treatment plants serve as the flushing

Full Text Available This article analyzes the trajectory of two secret organizations that were formed between 1835 and 1840. The first appeared in Uruguay and the second in Buenos Aires, and both were created for the purpose of overthrowing the regime of Juan Manuel de Rosas in Argentina. Despite the fact that neither was completely successful in achieving said objective, the article aims to reveal their strategies, their communication systems, their plans and the internal relations among their members. The conclusion is that these lodges played a determining role in the complex machinery of opposition since they constituted an important component in the persistent drive to oust Rosas, which would not be completely successful until the battle that finally liquidated him in Caseros (1852.

To assess and compare the antimicrobial potential and determine the minimum inhibitory concentration (MIC) of Jasminum grandiflorum and Hibiscus rosa-sinensis extracts as potential anti-pathogenic agents in dental caries. Aqueous and ethanol (cold and hot) extracts prepared from leaves of Jasminum grandiflorum and Hibiscus rosa-sinensis were screened for in vitro antimicrobial activity against Streptococcus mutans and Lactobacillus acidophilus using the agar well diffusion method. The lowest concentration of every extract considered as the minimum inhibitory concentration (MIC) was determined for both test organisms. Statistical analysis was performed with one-way analysis of variance (ANOVA). At lower concentrations, hot ethanol Jasminum grandiflorum (10 μg/ml) and Hibiscus rosa-sinensis (25 μg/ml) extracts were found to have statistically significant (P≤0.05) antimicrobial activity against S. mutans and L. acidophilus with MIC values of 6.25 μg/ml and 25 μg/ml, respectively. A proportional increase in their antimicrobial activity (zone of inhibition) was observed. Both extracts were found to be antimicrobially active and contain compounds with therapeutic potential. Nevertheless, clinical trials on the effect of these plants are essential before advocating large-scale therapy.

Plate interaction between Caribbean and Nazca plates with Southamerica gave rise to an intricate pattern of tectonic blocks in the Northandean realm. Among these microblocks the Sierra Nevada de Santa Marta (SNSM) represents a fault-bounded triangular massif composed of a representative crustal section of the Northandean margin, in which a Precambrian to Late Paleozoic metamorphic belt is overlain by a Triassic to Jurassic magmatic arc and collateral volcanic suites. Its western border fault belongs to the composite Bucaramanga - Santa Marta fault with a combined left lateral-normal displacement. SE of Santa Marta it exposes remnants of an Oligocene marginal basin, which attests to a first Cenoizoic activation of this crustal-scale lineament. The basin fill consists of a sequence of coarse-grained cobble-pebble conglomerates > 1000 m thick that unconformably overlay the Triassic-Jurassic magmatic arc. Its lower sequence is composed of interbedded siltstones; topwards the sequence becomes dominated by coarser fractions. These sedimentary sequences yields valuable information about exhumation and coeval sedimentation processes that affected the massif's western border since the Upper Eocene. In order to analyse uplifting processes associated with tectonics during early Neogene we performed detrital zircon U-Pb geochronology, detrital thermochronology of zircon and apatites coupled with the description of a stratigraphic section and its facies composition. We compared samples from the Aracataca basin with analog sequences found at an equivalent basin at the Oca Fault at the northern margin of the SNSM. Our results show that sediments of both basins were sourced from Precambrian gneisses, along with Mesozoic acid to intermediate plutons; sedimentation started in the Upper Eocene-Oligocene according to palynomorphs, subsequently in the Upper Oligocene a completion of Jurassic to Cretaceous sources was followed by an increase of Precambrian input that became the dominant

Synthesis of silver nanoparticles has been developed by using aqueous leaves extract (ALE) of Hibiscus rosa sinensis (H. rosa sinensis) and Imperata cylindrica (I. cylindrica). Both plants extract acts as reducing and capping agent. The colour change in reaction mixture (pale yellow to dark brown) was observed during the synthesis process. The formation of silver nanoparticles was confirmed by surface Plasmon Resonance (SPR) at range 300-700 nm for both leaves using UV-Vis Spectroscopy. The reduction of silver ions to silver nanoparticles was completed within 2 hour for H. rosa sinensis and 30 minutes for I. cylindrica extract. The synthesized nanoparticles were characterized using UV-Vis spectroscopy, field emission scanning electron microscope (FESEM) and Fourier transform infrared (FTIR) spectroscopy. The morphology of silver nanoparticles was found to be different when synthesized using different plant extract. In addition, this study also reported on the effect of silver nanoparticles on the degradation of organic dye by sodium borohydride (NaBH4). The silver nanoparticles synthesis by aqueous leaf extract demonstrates rapid, simple and inexpensive method compared to the conventional physical and physical methods. The efficiency of silver nanoparticles as a promising candidate for the catalysis of organic dyes by NaBH4 through the electron transfer is established in the present study.

1970-01-01

Streamflow records obtained in the upper Santa Cruz River basin of southern Arizona, United States, and northern Sonora, Mexico, have been analyzed to aid in the appraisal of the surface-water resources of the area. Records are available for 15 sites, and the length of record ranges from 60 years for the gaging station on the Santa .Cruz River at Tucson to 6 years for Pantano Wash near Vail. The analysis provides information on flow duration, low-flow frequency magnitude, flood-volume frequency and magnitude, and storage requirements to maintain selected draft rates. Flood-peak information collected from the gaging stations has been projected on a regional basis from which estimates of flood magnitude and frequency may be made for any site in the basin. Most streams in the 3,503-square-mile basin are ephemeral. Ground water sustains low flows only at Santa Cruz River near Nogales, Sonoita Creek near Patagonia, and Pantano Wash near Vail. Elsewhere, flow occurs only in direct response to precipitation. The median number of days per year in which there is no flow ranges from 4 at Sonoita Creek near Patagonia to 335 at Rillito Creek near Tomson. The streamflow is extremely variable from year to year, and annual flows have a coefficient of variation close to or exceeding unity at most stations. Although the amount of flow in the basin is small most of the time, the area is subject to floods. Most floods result from high-intensity precipitation caused by thunderstorms during the period ,July to September. Occasionally, when snowfall at the lower altitudes is followed by rain, winter floods produce large volumes of flow.

Differences in the competitive performance characteristics of junior and professional tennis players are not well understood. The present study provides a comprehensive comparative analysis of junior and professional matchplay. The study utilized multiple large-scale datasets covering match, point, and shot outcomes over multiple years of competition. Regression analysis was used to identify differences between junior and professional matchplay. Top professional men and women were found to play significantly more matches, sets, and games compared to junior players of an equivalent ranking. Professional players had a greater serve advantage, men winning 4 and women winning 2 additional percentage points on serve compared to juniors. Clutch ability in break point conversion was 6 to 8 percentage points greater for junior players. In general, shots were more powerful and more accurate at the professional level with the largest differences observed for male players on serve. Serving to the center of the court was more than two times more common for junior players on first serve. While male professionals performed 50% more total work in a Grand Slam match than juniors, junior girls performed 50% more work than professional women. Understanding how competitiveness, play demands, and the physical characteristics of shots differ between junior and professional tennis players can help set realistic expectations and developmentally appropriate training for transitioning players.

The espousal of nano technology is a current come-up of the present revolution. As we know that the rose aphid, Macrosiphum rosae (Hemiptera: Aphididae), is a key pest on rose plant in Kashmir Valley, India, it exhibits a worldwide distribution. In the present study, we have synthesized biologically silver nanoparticles (Ag NPs) from Solanum lycopersicum and characterized them by UV-vis spectroscopy, TEM, and X-RD analysis. The experiment was performed by leaf dip method. Insecticidal solutions of different Ag NPs concentrations, namely, 200, 300, 400, and 500 ppm, were tested on M. rosae. For assessment purposes, leaves were treated with distilled water (used as control). Aphid mortality data revealed that the Ag NPs were effective at 500 ppm concentration. As the concentration and day’s treatment increased, the aphid mortality rate also increased. There were statistically significant differences in M. rosae mortality between concentrations by LSD at 5%. In wrapping up, the use of Ag NPs in pest control processes will be the most novel eco-friendly approach in the Kashmir Valley, India, in future.

Handwashing, respiratory hygiene and antibiotic resistance remain major public health concerns. In order to facilitate an effective outcome when teaching the basic principles of hand and respiratory hygiene, educational interventions should first target school children. As computer games are ubiquitous in most children's lives, e-Bug developed computer games targeted at teaching children handwashing, respiratory hygiene and antibiotic resistance. The games were designed for two target audiences: junior school children (9-12 year olds); and senior school children (13-15 year olds). Between May and August 2009, the finalized junior game underwent an evaluation in three UK schools (in Glasgow, Gloucester and London), involving 62 children in the schools and ∼ 1700 players accessing the junior game online. The e-Bug junior game consists of a number of levels of play, each of which promotes a set of learning outcomes (LOs). These LOs, complementary to those in the e-Bug packs, are expressed through the game mechanics (the rules of the game) rather than through story or dialogue. Although the junior game's evaluation demonstrated a statistically significant change in the knowledge for only a small number of given LOs, because many children had the required knowledge already before playing the game, this is e-Bug's first statistical study on the junior game and the first comprehensive evaluation of its kind. Future work includes a re-examination of the quiz-style questionnaires utilized in this study and an exploration of the potential knowledge change acquired strictly through engagement.

Santa Ana winds, common to southern California during the fall through spring, are a type of katabatic wind that originates from a direction generally ranging from 360°/0° to 100° and is usually accompanied by very low humidity. Since fuel conditions tend to be driest from late September through the middle of November, Santa Ana winds occurring during this period have the greatest potential to produce large, devastating fires when an ignition occurs. Such catastrophic fires occurred in 1993, 2003, 2007, and 2008. Because of the destructive nature of these fires, there has been a growing desire to categorize Santa Ana wind events in much the same way that tropical cyclones have been categorized. The Santa Ana Wildfire Threat index (SAWT) is an attempt to categorize such events with respect to fire activity, based on surface wind velocity, dew point depression, and forecasted fuel conditions. The index, a USDA Forest Service product, was developed by the Forest Service in collaboration with San Diego Gas and Electric Utility (SDG&E), the Department of Atmospheric and Oceanic Sciences at UCLA, The Desert Research Institute (DRI), and Vertum Partners. The methodology behind the SAWT index, along with the index itself will be presented in detail. Also, there will be a discussion on the construction of a 30-year climatology of the index, which includes various meteorological and fuel parameters. We will demonstrate the usefulness of the index as another decision support tool for fire agencies and first responders, and how it could assist the general public and private industry in the preparation of critical Santa Ana wind events.

Hydrosols of orange blossom (Citrus aurantium), and rose flower (Rosa damascena and Rosa centifolia) support the growth of a heterogeneous spoilage microbiota.

Hydrosols are hydrodistillation products of aromatic plants. They contain less than 1g/L of dispersed essential oils giving organoleptic properties. Hydrosols are subjected to microbial proliferation. Reasons for spoilage have to be found in the nature of substrates supporting growth and of microbiological contaminants. The composition in essential oils and the microbiota of 22 hydrosol samples of Citrus aurantium L. ssp. amara L. (orange blossom), Rosa damascena Miller (rose D.), and Rosa centifolia L. (rose C.) flowers were analyzed to determine the factors responsible for decay. The median concentrations in essential oils were 677mg/L for orange blossom hydrosols, 205mg/L for rose D. hydrosols, and 116mg/L for rose C. hydrosols. The dry matter content of these hydrosols varied between 4.0mg/L and 702mg/L, and the carbohydrate content varied between 0.21mg/L and 0.38mg/L. These non-volatile compounds were likely carried over during distillation by a priming and foaming effect, and could be used as nutrients by microorganisms. A microbial proliferation at ambient temperature and also at 5°C has been observed in all studied hydrosols when stored in a non-sterile container. In contaminated hydrosols, maximal counts were about 7log 10 CFU/mL, while the French pharmacopeia recommends a maximal total bacterial count of 2log 10 CFU/mL. Neither yeast nor mold was detected. The isolated microbial population was composed of environmental Gram-negative bacteria, arranged in four major genera: Pseudomonas sp., Burkholderia cepacia complex, and presumably two new genera belonging to Acetobacteraceae and Rhodospirillaceae. Among those bacteria, Burkholderia vietnamiensis and Novosphingobium capsulatum were able to metabolize volatile compounds, such as geraniol to produce 6-methyl-5-hepten-2-one or geranic acid, or phenylethyl acetate to produce 2-phenylethanol. EO concentrations in hydrosols or cold storage are not sufficient to insure microbiological stability. Additional

O experimento foi arranjado em esquema de parcelas subdivididas, tendo nas parcelas as coberturas vegetais e nas subparcelas, as plantas medicinais. As plantas para a cobertura vegetal foram propagadas por semeadura direta no local de cultivo, enquanto as medicinais foram transplantadas diretamente entre a palhada da cobertura vegetal. A produção da mucuna preta foi de 8,37 t ha-1 de massa seca e do feijão de porco, de 14,37 t ha-1 de massa seca. O uso das culturas de cobertura contribuiu para uma maior biomassa microbiana do solo. As produções de massas frescas de folhas, caules e frutos de vinagreira e de frutos da pimenta rosa foram maiores quando cultivadas em sucessão às coberturas vegetais do solo, independente da espécie. As produções da carobinha foram semelhantes quando cultivadas em áreas com ou sem a cobertura. Visando à maior produtividade da vinagreira e pimenta rosa, são indicadas as culturas antecessoras feijão de porco e mucuna preta.

2013-01-01

Despite the popularity of open-wheel car racing, scientific literature about the physical characteristics of competitive race car drivers is scarce. The purpose of this study was to compare selected fitness parameters of experienced and junior open-wheel race car drivers. The experienced drivers consisted of five Formula One, two GP2 and two Formula 3 drivers, and the nine junior drivers drove in the Formula Master, Koenig, BMW and Renault series. The following fitness parameters were tested: multiple reactions, multiple anticipation, postural stability, isometric upper body strength, isometric leg extension strength, isometric grip strength, cyclic foot speed and jump height. The group differences were calculated using the Mann-Whitney U-test. Because of the multiple testing strategy used, the statistical significance was Bonferroni corrected and set at P < 0.004. Significant differences between the experienced and junior drivers were found only for the jump height parameter (P = 0.002). The experienced drivers tended to perform better in leg strength (P = 0.009), cyclic foot speed (P = 0.024) and grip strength (P = 0.058). None of the other variables differed between the groups. The results suggested that the experienced drivers were significantly more powerful than the junior drivers: they tended to be quicker and stronger (18% to 25%) but without statistical significance. The experienced drivers demonstrated excellent strength and power compared with other high-performance athletes.

Gender stereotypes in science impede supportive environments for women. Research suggests that women's perceptions of these environments are influenced by stereotype threat (ST): anxiety faced in situations where one may be evaluated using negative stereotypes. This study developed and tested ST metrics for first time use with junior faculty in academic medicine. Under a 2012 National Institutes of Health Pathfinder Award, Stanford School of Medicine's Office of Diversity and Leadership, working with experienced clinicians, social scientists, and epidemiologists, developed and administered ST measures to a representative group of junior faculty. 174 School of Medicine junior faculty were recruited (62% women, 38% men; 75% assistant professors, 25% instructors; 50% white, 40% Asian, 10% underrepresented minority). Women reported greater susceptibility to ST than did men across all items including ST vulnerability (p gender identification (p women reported lower beliefs in advancement (p = 0.021); however, they had similar career interest and identification, felt just as connected to colleagues, and were equally likely to pursue careers outside academia (all p > 0.42). Innovative ST metrics can provide a more complete picture of academic medical center environments. While junior women faculty are susceptible to ST, they may not yet experience all of its consequences in their early careers. As such, ST metrics offer a tool for evaluating institutional initiatives to increase supportive environments for women in academic medicine.

Seed dispersal by birds is central to the passive restoration of many tree communities. Reintroduction of extinct seed dispersers can therefore restore degraded forests and woodlands. To test this, we constructed a spatially explicit simulation model, parameterized with field data, to consider the effect of different seed dispersal scenarios on the extent of oak populations. We applied the model to two islands in California's Channel Islands National Park (USA), one of which has lost a key seed disperser.We used an ensemble modelling approach to simulate island scrub oak (Quercus pacifica) demography. The model was developed and trained to recreate known population changes over a 20-year period on 250-km2 Santa Cruz Island, and incorporated acorn dispersal by island scrub-jays (Aphelocoma insularis), deer mice (Peromyscus maniculatus) and gravity, as well as seed predation. We applied the trained model to 215-km2 Santa Rosa Island to examine how reintroducing island scrub-jays would affect the rate and pattern of oak population expansion. Oak habitat on Santa Rosa Island has been greatly reduced from its historical extent due to past grazing by introduced ungulates, the last of which were removed by 2011.Our simulation model predicts that a seed dispersal scenario including island scrub-jays would increase the extent of the island scrub oak population on Santa Rosa Island by 281% over 100 years, and by 544% over 200 years. Scenarios without jays would result in little expansion. Simulated long-distance seed dispersal by jays also facilitates establishment of discontinuous patches of oaks, and increases their elevational distribution.Synthesis and applications. Scenario planning provides powerful decision support for conservation managers. We used ensemble modelling of plant demographic and seed dispersal processes to investigate whether the reintroduction of seed dispersers could provide cost-effective means of achieving broader ecosystem restoration goals on

To examine the influence of newspaper and Internet advertising, word-of-mouth endorsement and student experience in attracting applicants for junior medical officer positions in the Northern Territory. A retrospective study. Fifty-four applicants for junior medical officer positions. Proportion of applicants who reported newspaper advertising, Internet advertising, word of mouth or personal experience in attracting their application for an intern or resident medical officer position. Nineteen per cent of applicants saw the newspaper advertisement and 52% of the Internet advertisement. Eighty-seven per cent of applicants were influenced by word-of-mouth endorsement and 52% by student experience in the Northern Territory or Indigenous health. These results suggest that word-of-mouth endorsement has the greatest influence in attracting applicants for junior medical officer positions in Northern Territory hospitals.

Shirai, Nobu; Imura, Tomoko; Tamura, Rio; Seno, Takeharu

2014-01-01

Previous studies have shown that even elementary school-aged children (7 and 11 years old) experience visually induced perception of illusory self-motion (vection) (Lepecq et al., 1995, Perception, 24, 435-449) and that children of a similar age (mean age = 9.2 years) experience more rapid and stronger vection than do adults (Shirai et al., 2012, Perception, 41, 1399-1402). These findings imply that although elementary school-aged children experience vection, this ability is subject to further development. To examine the subsequent development of vection, we compared junior high school students' (N = 11, mean age = 14.4 years) and adults' (N = 10, mean age = 22.2 years) experiences of vection. Junior high school students reported significantly stronger vection than did adults, suggesting that the perceptual experience of junior high school students differs from that of adults with regard to vection and that this ability undergoes gradual changes over a relatively long period of development.

The emergence of mobile computing could have an impact on how junior doctors learn. To exploit this opportunity it is essential to understand their information seeking process. To explore junior doctors' experiences of using medical knowledge sources on handheld computers. Interviews with five Swedish junior doctors. A qualitative manifest content analysis of a focus group interview followed by a qualitative latent content analysis of two individual interviews. A focus group interview showed that users were satisfied with access to handheld medical knowledge sources, but there was concern about contents, reliability and device dependency. Four categories emerged from individual interviews: (1) A feeling of uncertainty about using handheld technology in medical care; (2) A sense of security that handhelds can provide; (3) A need for contents to be personalized; (4) A degree of adaptability to make the handheld a versatile information tool. A theme was established to link the four categories together, as expressed in the Conclusion section. Junior doctors' experiences of using medical knowledge sources on handheld computers shed light on the need to decrease uncertainty about clinical decisions during medical internship, and to find ways to influence the level of self-confidence in the junior doctor's process of decision-making.

Aim Rosa damascene Mill. belongs to the family of Roseaceae and its essential oil is produced in large amounts in Iran. The wide application of rose oil has raised questions about potential adverse health effects. We have investigated cytotoxic activity and genotoxic effects of Rosa oil from Kashan, Iran. Methods The cytotoxic effect and IC50 of the essential oil on the cell lines was studied followed by MTT assay. In this assay mitochondrial oxidoreductase enzymes with reducing the tetrazolium dye MTT (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) reflect the number of viable cells. Genotoxic effect of the oil was evaluated by micronucleus assay by evaluating produced micronuclei due to cytogenetic damage in binucleated lymphocytes. Results The results showed that essential oil significantly had cytotoxic and genotoxic effects at doses over 10µg/mL (pessential oil of Rose showed lower IC50 in cancer cell line (A549) in comparison with the normal cell line (NIH3T3). Conclusion Cytotoxic and genotoxic properties of essential oil of Rose in Kashan, Iran, are safe at a dose of 10µg/mL. Also, a good cytotoxic effect was shown and could be introduced as an anticancer compound. Further studies are needed with regard to anti-cancer effects of Rose essential oil.

2011-02-01

A previously published systematic review and a metaanalysis have concluded that the consumption of standardized rose hip powder (Rosa canina L.) can reduce pain in osteoarthritis patients. Synovial inflammation has been suggested to play an important role in the pathogenesis of osteoarthritis and mainly to involve infiltration of the synovial membrane by macrophages. Therefore, the immunomodulatory effect of standardized rose hip powder of Rosa canina L. was investigated and active principles isolated using the Mono Mac 6 cell line as a model for human macrophages. Treatment of Mono Mac 6 cells with the residue of a crude dichloromethane extract of rose hip powder significantly and concentration dependently inhibited the lipopolysaccharide induced interleukin-6 release. Through bioassay-guided fractionation the immunomodulatory effect of the dichloromethane extract was correlated to a mixture of three triterpene acids; oleanolic acid, betulinic acid and ursolic acid (IC(50) 21 ± 6 µm). Further studies revealed that only oleanolic acid and ursolic acid, but not betulinic acid, could inhibit the lipopolysaccharide induced interleukin-6 release from Mono Mac 6 cells when tested separately. Combination of either oleanolic acid or ursolic acid with betulinic acid enhanced the immunomodulatory effect of the two triterpene acids. Copyright © 2010 John Wiley & Sons, Ltd.

2014-05-01

The peopling, origins, and early prehistory of the Americas are topics of intense debate. However, few studies have used human remains to document and interpret patterns of health and lifestyle of Paleoamericans. This study provides the first investigation to characterize oral health in a series of early Holocene skeletal remains from Lagoa Santa, Brazil, a locality containing the remains of some of the earliest inhabitants of South America (10,000-7,000 BP). The sample is composed of 949 teeth and 1925 alveoli from an estimated 113 individuals excavated from 17 archaeological sites located in the State of Minas Gerais. We compare dental caries and abscess prevalence at Lagoa Santa to a large sample of human skeletons from the Western Hemisphere Project (WHP) database using both individual and tooth/alveolus count methods. In addition, antemortem tooth loss and tooth wear were analyzed in Lagoa Santa by sex and age. The results show that Lagoa Santa dental caries and abscess prevalence are significantly higher than observed among other hunter-gatherers included in the WHP database, except when abscess prevalence is considered by individual count. Adult females have less tooth wear coupled with higher prevalence of dental caries and antemortem tooth loss than adult males. These results point to an unexpected record of poor oral health at Lagoa Santa, especially among females. A diet based on a highly cariogenic combination of wild tubers and fruits is suggested as an explanation for the elevated rate, characterizing an early adaptation to a tropical environment in South America.

Full Text Available Predicting current and future tennis performance can lead to improving the development of junior tennis players. The aim of this study is to investigate whether age, maturation, or physical fitness in junior elite tennis players in U13 can explain current and future tennis performance. The value of current tennis performance for future tennis performance is also investigated. A total of 86 junior elite tennis players (boys, n = 44; girls, n = 42 U13 (aged: 12.5 ± 0.3 years, and followed to U16, took part in this study. All players were top-30 ranked on the Dutch national ranking list at U13, and top-50 at U16. Age, maturation, and physical fitness, were measured at U13. A principal component analysis was used to extract four physical components from eight tests (medicine ball throwing overhead and reverse, ball throwing, SJ, CMJas, Sprint 5 and 10 meter, and the spider test. The possible relationship of age, maturation, and the physical components; “upper body power”, “lower body power”, “speed”, and “agility” with tennis performance at U13 and U16 was analyzed. Tennis performance was measured by using the ranking position on the Dutch national ranking list at U13 and U16. Regression analyses were conducted based on correlations between variables and tennis performance for boys and girls, separately. In boys U13, positive correlations were found between upper body power and tennis performance (R2 is 25%. In girls, positive correlations between maturation and lower body power with tennis performance were found at U13. Early maturing players were associated with a better tennis performance (R2 is 15%. In girls U16, only maturation correlated with tennis performance (R2 is 13%; later-maturing girls at U13 had better tennis performances at U16. Measuring junior elite tennis players at U13 is important for monitoring their development. These measurements did not predict future tennis performance of junior elite tennis players three

Migration intentions among Portuguese junior doctors: Results from a survey.

Science.gov (United States)

Ramos, Pedro; Alves, Hélio

2017-12-01

Migration of health personnel during periods of economic crisis represents a challenge for policymakers in origin and destination countries. Portugal is going through a period of economic hardship and much has been speculated about an increase in junior doctors' migration during this period. Using a questionnaire administered to a sample of Portuguese junior doctors who were still in the general residency (1st-year after medical school), we aim at determining the prevalence of migration intentions among Portuguese junior doctors and to identify the most important drivers of career choice for those who are considering emigrating in the near future. In our sample, 55% of Portuguese junior doctors are considering working abroad in the coming 10 years. Several variables were associated with an intention to work abroad: female sex (odds ratio [OR] 0.559; 95% confidence interval [CI] 0.488-0.640), the National Medical Exam score (OR 0.978; 95% CI 0.961-0.996;), having studied abroad (OR 1.756; 95% CI 1.086-2.867) and considering income and research opportunities as key factors for future specialty choice (OR 1.356; 95% CI 1.132-1.626; OR 2.626; 95% CI 1.228-4.172). Our study warns of the shortages the country may face due to doctors' migration and the main factors behind migration intentions in Portugal. Developing physician retention strategies is a priority to appropriately address these factors. Copyright © 2017 Elsevier B.V. All rights reserved.

Perspectives on the working hours of Australian junior doctors.

Science.gov (United States)

Glasgow, Nicholas J; Bonning, Michael; Mitchell, Rob

2014-01-01

The working hours of junior doctors have been a focus of discussion in Australia since the mid-1990s. Several national organizations, including the Australian Medical Association (AMA), have been prominent in advancing this agenda and have collected data (most of which is self-reported) on the working hours of junior doctors over the last 15 years. Overall, the available data indicate that working hours have fallen in a step-wise fashion, and AMA data suggest that the proportion of doctors at high risk of fatigue may be declining. It is likely that these changes reflect significant growth in the number of medical graduates, more detailed specifications regarding working hours in industrial agreements, and a greater focus on achieving a healthy work-life balance. It is notable that reductions in junior doctors' working hours have occurred despite the absence of a national regulatory framework for working hours. Informed by a growing international literature on working hours and their relation to patient and practitioner safety, accreditation bodies such as the Australian Commission on Safety and Quality in Health Care (ACSQHC) and the Australian Medical Council (AMC) are adjusting their standards to encourage improved work and training practices.

CARACTERIZAÇÃO FÍSICA, QUÍMICA E NUTRICIONAL DA PITAIA-ROSA DE POLPA VERMELHA

Talent identification (TID) is a pertinent component of the sports sciences, affording practitioners the opportunity to target developmental interventions to a select few; optimising financial investments. However, TID is multi-componential, requiring the recognition of immediate and prospective performance. The measurement of athletic movement skill may afford practitioners insight into the latter component given its augmented relationship with functional sport specific qualities. It is currently unknown whether athletic movement skill is a discriminant quality in junior Australian football (AF). This study aimed to discriminate talent identified junior AF players from their non-talent identified counterparts using a fundamental gross athletic movement assessment. From a total of 50 under 18 (U18) AF players; two groups were classified a priori based on selection level; talent identified (n = 25; state academy representatives) and non-talent identified (n = 25; state-based competition representatives). Players performed a fundamental gross athletic movement assessment based on the Athletic Ability Assessment (AAA), consisting of an overhead squat, double lunge (left and right legs), single leg Romanian deadlift (left and right legs), and a push up (six movement criterions). Movements were scored across three assessment points using a three-point scale (resulting in a possible score of nine for each movement). A multivariate analysis of variance revealed significant between group effects on four of the six movement criterions (d = 0.56 – 0.87; p = 0.01 – 0.02). Binary logistic regression models and a receiver operating characteristic curve inspection revealed that the overhead squat score provided the greatest group discrimination (β(SE) = -0.89(0.44); p talent identified and non-talent identified groups, respectively. Results support the integration of this assessment into contemporary talent identification approaches in junior AF, as it may provide coaches

The purpose of this study was to investigate pedicle screw placement accuracy during navigated surgery by a junior spine surgeon who had no spinal surgery experience. A junior spine surgeon with no spinal surgery experience implanted a total of 137 pedicle screws by using a navigation system. Postoperative computerized tomography was performed to evaluate screw placement, and the pedicle perforation rate was 2.2%. There were no neurologic or vascular complications related to the pedicle screws. The results demonstrated that pedicle screws can be placed safely and effectively by a junior spine surgeon who has no spinal surgery experience when instructed by a senior spine surgeon. The results of this study suggest that navigation can be used as a surgical training tool for junior spine surgeons. (author)

To explore the collaboration experiences of junior physicians and nurses in the general ward setting. Junior physicians and nurses do not always work collaboratively and this could affect the quality of patient care. The understanding of the issues affecting junior physicians and nurses working together is needed to inform strategies to improve interprofessional collaboration. Nineteen junior physicians and nurses were interviewed in 2012 and 2013. Interviews were transcribed and analysed using thematic analysis. Junior physicians and nurses acknowledged the importance of working collaboratively to achieve better patient care, but they are struggling to cope due to heavy clinical workload, organisational constraints and differing power relationships. Nurses have to take on more responsibilities in the decision-making process of patients' care to foster effective interprofessional collaboration. The study calls for educational and organisational strategies to improve interprofessional collaboration between junior physicians and nurses. Nurse leaders should ensure that ward nurses are given a designated time to participate in ward rounds with physicians and have access to a communication tool that assists them in contributing proactively in the decision-making process of patient care. © 2017 John Wiley & Sons Ltd.

A partir daí, ocorreram poucos casos autóctones isolados, e esporádicos. No entanto, em função da existência do vetor em seu território, da existência de extensa área endêmica no Brasil e da grande mobilidade de pessoas em áreas turísticas no estado, existe a probabilidade de reintrodução da doença. MÉTODOS: Utilizou-se os seguintes dados: Banco de Dados do Núcleo de Entomologia da Fundação Nacional de Saúde, Santa Catarina (ACCES,1997-2000; Sistema de Informação de Vigilância Epidemiológica, Secretaria de Vigilância em Saúde (Malária/SC e Sistema de Informação de Notificação e Agravo(SINAN/SC.

For this purpose, we start by presenting the concerns of Antero de Quental and Eça de Queiroz, and then approaching the literary work of Aquilino Ribeiro, specifically O romance da raposa, following with the approach present in the literary work of Matilde Rosa Araújo. 

Ground-water quality in the Santa Rita, Buellton, and Los Olivos hydrologic subareas of the Santa Ynez River basin, Santa Barbara County, California

Hamlin, S.N.

1985-01-01

Groundwater quality in the upper Santa Ynez River Valley in Santa Barbara County has degraded due to both natural and anthropogenic causes. The semiarid climate and uneven distribution of rainfall has limited freshwater recharge and caused salt buildup in water supplies. Tertiary rocks supply mineralized water. Agricultural activities (irrigation return flow containing fertilizers and pesticides, cultivation, feedlot waste disposal) are a primary cause of water quality degradation. Urban development, which also causes water quality degradation (introduced contaminants, wastewater disposal, septic system discharge, and land fill disposal of waste), has imposed stricter requirements on water supply quality. A well network was designed to monitor changes in groundwater quality related to anthropogenic activities. Information from this network may aid in efficient management of the groundwater basins as public water supplies, centered around three basic goals. First is to increase freshwater recharge to the basins by conjunctive surface/groundwater use and surface-spreading techniques. Second is to optimize groundwater discharge by efficient timing and spacing of pumping. Third is to control and reduce sources of groundwater contamination by regulating wastewater quality and distribution and, preferably, by exporting wastewaters from the basin. (USGS)

This study examined changes in academic motivation among elementary and junior high school students. Based on self-determination theory (Ryan & Deci, 2000a), we focused on changes in autonomous and controlled motivation. In Study 1, we examined inter-individual changes in academic motivation among 5th to 9th grade students (N = 1 572) through a cross-sectional study. In Study 2, we examined intra-individual changes in academic motivation among students (N = 128) who were in transition from elementary to junior high school through a longitudinal study. All participants completed the Academic Motivation Scale (Nishimura, Kawamura, & Sakurai, 2011) that measured autonomous and controlled motivation. The results revealed that autonomous motivation decreased in the students from elementary to junior high school, while controlled motivation increased during the same period. This is a unique finding because a prior study conducted in a Western culture suggested that both motivations decrease gradually in school.

Increasing professionalism in competitive karate has led to a specific injury pattern. The aim of our study was to investigate the injury pattern in junior competitive karate and to evaluate the prophylactic effect of fist padding. During the 4 (th) Junior World Championships of the World Karate Confederation (WKC) 2004 235 karate fights were observed and injury-related data were recorded. Fist padding was used in 183 fights, 52 fights were carried out without. In 22 % of all fights we saw an injury. Most of them were mild injuries of the head and face: 32 bruises of the face (13 with epistaxis), 7 facial lacerations and 3 concussions (mild brain injury). 14 fights were stopped due to an injury. Only in the category male 18 - 20 years a higher rate of injuries was seen without fist padding (shobu ippon) compared to shobu sanbon (with fist padding). The injury pattern of junior competitive karate is comparable to senior karate. Fist padding does not generally reduce the incidence or severity of injuries.

Full Text Available The wildlife trade is becoming increasingly more relevant in discussions concerning conservation biology and the sustainable management of natural resources. The aim of this study was to document the trade and breeding of wildlife in Santa Catarina state, in southern Brazil. Data was collected from annual reports (1996-2008 of wildlife breeders which were sent to IBAMA. By the end of 2008, there were 79 wildlife breeders and 11 wildlife traders distributed in Santa Catarina. Commercial breeding accounted for the highest number of breeders (51%. In total, there are 213 species of wild animals bred in the state: 177 birds, 19 mammals and 17 reptiles. Of these, 48% are native to Santa Catarina, 32% occur in other Brazilian states and 20% are exotic to Brazil. Nine percent of the species bred are vulnerable or endangered. It was observed that some breeders reported breeding unauthorized species. Altogether, 93 species are bred illegally by 19 breeders. Of these species, 48 are native to Santa Catarina and three are classified as vulnerable or in danger of extinction. We hope the data presented in this paper contributes to the development of conservation strategies and conscious use of wildlife resources in Brazil.

Full Text Available Background  Apnea is one of the most common problems in preterm neonates. This study aimed to evaluate the effectiveness of aromatherapy on the reduction of apnea, bradycardia, and Pulse Oximetry (SPO2 in premature infants. Materials and Methods In a clinical trial study, 60 preterm neonates randomly divided in two groups and exposed to aromatherapy with Rosa damascenes distillate or distilled water beside the routine treatment. In experimental group, two drops of 10% Rosa damascenes distillate was dropped on the pad eye in second day of birth at 6 Am. The intervention was repeated in 9 AM, 12 Am, 15 PM and 18 PM hours. A same condition applied for control group and distilled water was dropped on the pad eye. The number of apnea attacks, bradycardia and decrease in SpO2 compared between two groups using chi-square test, independent t-test and repeated measure test. Results The overall apnea attacks, bradycardia, and SPO2 in tree studied days were lower in intervention group than control group (0.47±0.13 vs. 2.6±0.41, 0.47±0.13 vs. 2.56±0.41 and 0.70±0.17 vs. 2.77±0.21, respectively. In addition, the repeated measurement test showed that the mean number of apnea attacks, decrease in heart pulse rate, and decrease in SpO2 was statistically lower in intervention group with aromatherapy than controls in first, second, third and sum of three days (P< 0.05. Conclusion Aromatherapy with Rosa damascenes distillate can reduce more and speedy the occurrence of apnea attacks, bradycardia and SPO2 in premature infants, along with other routine treatment.

The sample included 2 quarterbacks (QB, 7 running backs (RB, 13 wide receivers (WR, 1 tight end (TE, 18 defensive backs (DB, 8 linebackers (LB, and 13 offensive and defensive linemen (LM. To investigate positional differences, subjects were split into skill (SK; WR, DB, big skill (BSK; QB, RB, TE, LB, and LM groups. A one-way ANOVA determined between-group differences. LM were taller and heavier than SK and BSK players. The SK and BSK groups were faster than LM in the 0–36.58 m sprint, pro-agility shuttle, and three-cone drill (p ≤ 0.009. The SK group had greater VJ height and SBJ distance; LM generated greater VJ peak power (p ≤ 0.022. There were no between-group differences in the strength endurance tests. Compared to Division I data, junior college players were smaller, slower, and performed worse in jump tests. Positional differences in junior college football are typical to that of established research. Junior college players should attempt to increase body mass, and improve speed and lower-body power.

Several studies have indicated that the population in general perceives doctors as reliable. In the present study perceptions of reliability and kindness attributed to another socially significant archetype, Santa Claus, have been comparatively examined in relation to the doctor. In all, 52 randomly chosen participants were shown a film, where a narrator dressed either as Santa Claus or as a doctor tells an identical story. Structured interviews were then used to assess the subjects' perceptions of reliability and kindness in relation to the narrator's appearance. We found a strong inclination for Santa Claus being perceived as friendlier than the doctor (p = 0.053). However, there was no significant difference in the perception of reliability between Santa Claus and the doctor (p = 0.524). The positive associations attributed to Santa Claus probably cause that he is perceived friendlier than the doctor who may be associated with more serious and unpleasant memories of illness and suffering. Surprisingly, and despite him being an imaginary person, Santa Claus was assessed as being as reliable as the doctor.

The TROJAN Project: Creating a Customized International Orthopedic Training Program for Junior Doctors.

Musculoskeletal problems account for a vast proportion of presentations encountered by doctors globally, with figures ranging from 15-36%. However, the time medical schools allocate to learning orthopedics is by no means proportional to this. This study aims to bridge this gap by developing an international orthopedic teaching program tailored to the specific knowledge and skills required by junior doctors in different countries. This prospective study asked fifty junior doctors, who had recently completed an orthopedics job, what three orthopedic teaching topics taught retrospectively would have benefitted their clinical practice. The most requested topics were used to design educational workshops for junior doctors and these consequently comprised the TROJAN (Teaching Requested by Orthopaedic Juniors And Novices) training program. Data was collected from twenty-five junior doctors in KwaZulu-Natale State, South Africa, and twenty-five in London, UK. It is therefore in these two countries that the TROJAN program was subsequently made available. Participants who selected topics were within two years of graduating medical school and had worked an orthopedic or Accident and Emergency job within the last year. 49% of topics chosen by SA doctors were practical skills such as wrist and ankle fracture reduction techniques, and management of open fractures. The most requested topic by UK doctors (11 out of 25) was management of neck of femur fractures. This is rationalized by the fact South African doctors require more hands-on responsibility in their daily practice whereas in the UK greater emphasis is placed on optimizing patients for theatre and making sound management plans. TROJAN currently develops orthopedic skills and knowledge in junior doctors in South Africa and United Kingdom with teaching customized based upon location. Feedback has been exceptionally positive with every candidate thus far rating the usefulness of TROJAN as the highest option, very useful.

Junior basketball athletes require a well-designed resistance training program to improve their physical development. Lack of expert supervision and resistance training in junior development pathways may be overcome by implementing an online video-based program. The aim of this study was to compare the magnitude of improvement (change) in physical performance and strength and functional movement patterns of junior basketball athletes using either a fully supervised or an online video-based resistance training program. Thirty-eight junior basketball athletes (males, n = 17; age, 14 ± 1 year; height, 1.79 ± 0.10 m; mass, 67 ± 12 kg; females, n = 21; age, 15 ± 1 year; height, 1.70 ± 0.07 m; mass, 62 ± 8 kg) were randomly assigned into a supervised resistance training group (SG, n = 13), video training group (VG, n = 13) or control group (CG, n = 12) and participated in a 6-week controlled experimental trial. Pre- and posttesting included measures of physical performance (20-m sprint, step-in vertical jump, agility, sit and reach, line drill, and Yo-Yo intermittent recovery level 1), strength (15 s push-up and pull-up), and functional movement screening (FMS). Both SG and VG achieved 3-5% ± 2-4% (mean ± 90% confidence limits) greater improvements in several physical performance measures (vertical jump height, 20-m sprint time, and Yo-Yo endurance performance) and a 28 ± 21% greater improvement in push-up strength compared with the CG. The SG attained substantially larger gains in FMS scores over both the VG (12 ± 10%) and CG (13 ± 8%). Video-based training appears to be a viable option to improve physical performance and strength in junior basketball athletes. Qualified supervision is recommended to improve functional movement patterns in junior athletes.

Jose, Ricardo; Clesham, Gerald J

2007-09-01

Anaphylaxis is a life threatening reaction where prompt and appropriate management can save lives. Epinephrine (adrenaline) is the treatment of choice; however, the recommended dose and route of administration of epinephrine used in the management of anaphylaxis is different from that used in the management of cardiac arrest. To investigate how junior doctors would administer epinephrine in a case of anaphylactic shock in an adult patient. Junior medical staff in two district general hospitals were assessed with a short questionnaire. 95 junior hospital doctors were assessed. The majority (94%) would administer epinephrine as the life saving drug of choice, but only 16.8% would administer it as recommended by the UK Resuscitation Council Guidelines. Junior doctors may be called to make immediate management decisions in patients with anaphylaxis; however, widespread confusion exists regarding the dose and route of administration of epinephrine. Strategies to improve education and access to appropriate drugs are needed. A labelled "anaphylaxis box" on every resuscitation trolley, containing the dose of epinephrine with clear labelling for intramuscular use, may be one solution.

Pethe, Mohan; Yelwatkar, Samir; Manchalwar, Smita; Gujar, Vijay

2017-08-01

Aim and Objective The current study sought to investigate antidiabetic, hypolipidimic, antioxidant and histopathological effects of floral extract of Hibiscus rosa sinensis in Alloxan induced Diabetes in rats. Materials and Methods Study was conducted on 6 groups with 6 wistar rats in each group for the period of 4 weeks. Group I: served as normal control (NC), rats administered with gum acacia 1 ml daily, group II: consider as diabetic control (DC) treated with alloxon 150 mg/kg body wt. Whereas Hibiscus rosa-sinensis flower extract was given orally in group III (DE1), group IV (DE2), group V (DE3) at doses of 50, 100 and 200 mg/kg body weight dissolved in distilled water respectively. Group VI (DG) was given glibenclamide (5 mg/kg) as a standard drug and results were compared in reference to it. Results The results indicate that the test compound HEFHR (Hydroalcoholic extract of flower Hibiscus rosa-sinensis) has significant and sustained oral antidiabetic activity, comparable with the hypoglycemic effect of Glibenclamide and Sulphonylurea. Flower extract of HRS was more efficacious in lipid lowering effect and in antioxidative activity than glibenclamide. After 28 day treatment with flower extract, size of islets was significantly increased and necrosis and atrophy of islets were significantly improved; also increase in number and diameter of cell islets appeared to be regular as compared to the diabetic group. Conclusion HEFHR possesses significant antidiabetic, hypolipidemic and antioxidant properties as well as regeneration of beta cells in rats. Further evaluation of HEFHR is in progress. © Georg Thieme Verlag KG Stuttgart · New York.

2017-10-01

Junior faculty face challenges in establishing independent research careers. Declining funding combined with a shift to multidisciplinary, collaborative science necessitates new mentorship models and enhanced institutional support. Two multidisciplinary mentorship programs to promote grant success for junior faculty were established at the Duke University School of Medicine beginning in 2011. These four-month programs-the Path to Independence Program (PtIP) for National Institutes of Health (NIH) R applicants and the K Club for NIH K applicants-use multiple senior faculty mentors and professional grant-writing staff to provide a 20-hour joint curriculum comprising a series of lectures, hands-on workshops, career development counseling, peer groups, and an internal study section. In March 2016, the authors analyzed the success rate for all NIH grants submitted by participants since program enrollment. In a 2015 postprogram survey, participants rated their feelings of support and competency across six skill factors. From October 2011 to March 2016, the programs engaged 265 senior faculty mentors, 145 PtIP participants, and 138 K Club participants. Success rates for NIH grant applications were 28% (61 awards/220 decisions) for PtIP participants-an increase over the 2010 Duke University junior faculty baseline of 11%-and 64% (38/59) for K Club participants. Respondents reported significantly increased feelings of support and self-ratings for each competency post program. The authors plan to expand the breadth of both the mentorship pool and faculty served. Broad implementation of similar programs elsewhere could bolster success, satisfaction, and retention of junior faculty investigators.

2014-12-01

Full Text Available Rose hip (Rosa canina L. is the pseudo-fruit of the rose plant, which is widely known as a valuable source of polyphenols and vitamin C. Both in vivo and in vitro studies have demonstrated that this fruit exhibits anti-inflammatory, antioxidant, and antiobesogenic activities. The health benefits of Rose hip (RH have been attributed to its wide range of bioactive compounds including the anti-inflammatory galactolipid: (2S-1,2-di-O-[(9Z,12Z,15Z-octadeca-9,12,15-trienoyl]-3-O-β-D galactopyranosyl glycerol (GOPO, vitamin C, phenolics, lycopene, lutein, zeaxanthin, and other carotenoids. As cyclooxygenase inhibitors, RH compounds may reduce the risk of cancer, heart disease, and various inflammatory conditions. The aim of this review is to present an overview of the functional, medical, and physiological properties of RH.

Carter, M.J.; Roe, D.; Keopo, J.

2012-01-01

Recent field investigations on Santa Isabel in the Central Solomon Islands have revealed the presence of archaeological pottery in both terrestrial and intertidal contexts. Preliminary dating results and comparative stylistic analyses of sherds provide evidence to suggest an antiquity of ceramics in northwest Isabel spanning the late Holocene to the recent historic past. These research outcomes expand the known distribution of pottery within the Solomon Islands and provide new knowledge about the prehistory of Santa Isabel. Here we describe the Santa Isabel ceramics, and suggest several implications of the research for current settlement models of the Solomon Islands and for our understanding of the variability in the archaeological record of mid- to late-Holocene ceramic distribution throughout the region.

Our group has previously demonstrated an upward shift from junior to senior resident participation in common general surgery operations, traditionally performed by junior-level residents. The objective of this study was to evaluate if this trend would correct over time. We hypothesized that junior resident case volume would improve. A sample of essential laparoscopic and open general surgery procedures (appendectomy, inguinal herniorrhaphy, cholecystectomy, and partial colectomy) was chosen for analysis. The American College of Surgeons National Surgical Quality Improvement Program Participant Use Files were queried for these procedures between 2005 and 2012. Cases were stratified by participating resident post-graduate year with "junior resident" defined as post-graduate year1-3. Logistic regression was performed to determine change in junior resident participation for each type of procedure over time. A total of 185,335 cases were included in the study. For 3 of the operations we considered, the prevalence of laparoscopic surgery increased from 2005-2012 (all p surgeries performed by junior-level residents decreased for appendectomy by 2.6%/y (p surgeries, with appendectomy decreasing by 9.4%/y (p surgery resident education.

We design and implement a cost-effective and compact 100-Gb/s (2 × 50 Gb/s) PAM-4 receiver optical sub-assembly (ROSA) by using a TO-can package instead of an expensive box-type package. It consists of an optical demultiplexer, two PIN-PDs and a 2-channel linear transimpedance amplifier. The components are passively aligned and assembled using alignment marks engraved on each part. With a real-time PAM-4 DSP chip, we measured the back-to-back receiver sensitivities of the 100-Gb/s ROSA based on TO-56 to be less than -13.2 dBm for both channels at a bit error rate of 2.4e-4. The crosstalk penalty due to the adjacent channel interference was observed around 0.1 dB.

Results of the ROSA-II tests simulating a loss-of-coolant accident (LOCA) and effects of an emergency core cooling system (ECCS) in a pressurized water reactor (PWR) are presented including the test conditions and interpretations of the data in test runs 327,328,329 and 330. Each test was performed with large double-ended hot leg break and effect of the break area distribution (break diameter are 25.0 mm at one end and 37.5 mm at the other end of break) and of pump circulation upon coolant flow in the core were studied. The following are the results: In the case of a smaller break on the steam generator side, core cooling was achieved due to upward coolant flow in the core and early reflooding by ACC water injected into the cold leg. In the case of a smaller break area on the vessel side, on the other hand, coolant flow in the core was stagnant and the heater rods were mostly exposed to steam, so that core cooling was not as good. Effect of the coolant circulation by acting pump on the core cooling during a blowdown was not significant except that in a steam generator side small break the core cooling was improved. (auth.)

Como se trata de um livro sobre livros, Umberto Eco chama a atenção para o caráter intertextual e fenomênico da escrita. Seu uso das técnicas do romance policial visa ao mesmo tempo distrair o leitor e apresentar um modelo de interpretação tanto de um mundo feito de sinais, quanto do próprio texto.

Full Text Available Skin cancer is extremely common, and melanoma causes about 80% of skin cancer deaths. In fact, melanoma kills over 50 thousand people around the world each year, and these numbers are rising. Clearly, standard treatments are not effectively treating melanoma, and alternative therapies are needed to address this problem. Hibiscus tea has been noted to have medicinal properties, including anticancer effects. Extracts from Hibiscus have been shown to inhibit the growth of a variety of cancer cells. In particular, recent studies found that polyphenols extracted from Hibiscus sabdariffa by organic solvents can inhibit melanoma cell growth. However, effects of aqueous extracts from Hibiscus rosa-sinesis flowers, which are commonly used to make traditional medicinal beverages, have not been examined on melanoma cells. Here, we report that aqueous H. rosa-sinesis flower extract contains compounds that inhibit melanoma cell growth in a dose dependent manner at concentrations that did not affect the growth of nontransformed cells. In addition, these extracts contain low molecular weight growth inhibitory compounds below 3 kD in size that combine with larger compounds to more effectively inhibit melanoma cell growth. Future work should identify these compounds, and evaluate their potential to prevent and treat melanoma and other cancers.

It has become increasingly important to expose surgical residents to robotic surgery as its applications continue to expand. Single-site robotic cholecystectomy (SSRC) is an excellent introductory case to robotics. Resident involvement in SSRC is known to be feasible. Here, we sought to determine whether it is safe to introduce SSRC to junior residents. A total of 98 SSRC cases were performed by general surgery residents between August 2015 and August 2016. Cases were divided into groups based on resident level: second- and third-years (juniors) versus fourth- and fifth-years (seniors). Patient age, gender, race, body mass index, and comorbidities were recorded. The number of prior laparoscopic cholecystectomies completed by participating residents was noted. Outcomes including operative time, console time, rate of conversion to open cholecystectomy, and complication rate were compared between groups. Juniors performed 54 SSRC cases, whereas seniors performed 44. There were no significant differences in patient age, gender, race, body mass index, or comorbidities between the two groups. Juniors had less experience with laparoscopic cholecystectomy. There was no significant difference in mean operative time (92.7 min versus 98.0 min, P = 0.254), console time (48.7 min versus 50.8 min, P = 0.639), or complication rate (3.7% versus 2.3%, P = 0.68) between juniors and seniors. SSRC is an excellent way to introduce general surgery residents to robotics. This study shows that with attending supervision, SSRC is feasible and safe for both junior and senior residents with very low complication rates and no adverse effect on operative time.

Concept: The objective of the project is to allow junior staff members from the European Technical Safety Organisations (TSOs), IRSN, GRS and AVN, to work together with the final goal of creating a junior staff network, based on technical, cultural and personal interests. These projects are to show junior staff members at a very early stage during their career the need for European collaborations. They are also a tool to explore new subjects of co-operation. It is an initiative that should strengthen the links between the organisations and contribute to establishing the future of nuclear safety in Europe. A JS3P (Junior Staff Programme Pilot Project) is a project done jointly by 'junior' staff members from the three TSOs, where experience of 'seniors' is also integrated when needed. Compared to other collaborative activities, it has certain specific features. The JS3P favours staff exchanges, and technical meetings of several days should be planned during a project in order to encourage people to work together. Technical objectives are shared and the work is done jointly (reports, articles). The team involved in the JS3P should be as small as possible to favour its efficiency. The JS3P is short and easy to realize. Its duration is fixed to a maximum of about 12 months with the option to be prolonged. Typical topics are bibliographic work, comparison issues, scientific surveys, benchmark exercises and prospective investigations on innovative ideas. They can be linked to existing joint projects and then form a smaller module integrated into the large project. Topics may concern prospective issues, tentatively investigating new topics that can be seen as exploratory co-operation projects. Subjects may also concern research issues that are not a priority but that deserve to be investigated as new attractive topics. The JS3P is defined and managed by junior staff members. It is approved by a management board committee and supervised by a technical steering committee

Academic faculty experience barriers to career development and promotion. In 1996, Harvard Medical School (HMS) initiated an intramural junior faculty fellowship to address these obstacles. The authors sought to understand whether receiving a fellowship was associated with more rapid academic promotion and retention. Junior faculty fellowship recipients and all other instructor and assistant professors at HMS between 1996 and 2011 were identified. Using propensity score modeling, the authors created a matched comparison group for the fellowship recipients based on educational background, training, academic rank, department, hospital affiliation, and demographics. Time to promotion and time to leaving were assessed by Kaplan-Meier curves. A total of 622 junior faculty received fellowships. Faculty who received fellowships while instructors (n = 480) had shorter times to promotion to assistant professor (P Women instructors advanced more quickly than matched controls, while male instructors' rates of promotions did not differ. Fellowships to support junior faculty were associated with shorter times to promotion for instructors and more sustained faculty retention for both instructors and assistant professors. This suggests that relatively small amounts of funding early in faculty careers can play a critical role in supporting academic advancement and retention.

In order to clarify molecular organization of the genomic region encoding 5S rRNA in diploid species Rosa rugosa several 5S rDNA repeated units were cloned and sequenced. Analysis of the obtained sequences revealed that only one length variant of 5S rDNA repeated units, which contains intact promoter elements in the intergenic spacer region (IGS) and appears to be transcriptionally active is present in the genome. Additionally, a limited number of 5S rDNA pseudogenes lacking a portion of coding sequence and the complete IGS was detected. A high level of sequence similarity (from 93.7 to 97.5%) between the IGS of major 5S rDNA variants of East Asian R. rugosa and North American R. nitida was found indicating comparatively recent divergence of these species.

To explore junior doctors' knowledge about and experiences of managing patients with medically unexplained symptoms (MUS) and to seek their recommendations for improved future training on this important topic about which they currently receive little education. Qualitative study using in-depth interviews analysed using the framework method. Participants were recruited from three North Thames London hospitals within the UK. Twenty-two junior doctors undertaking the UK foundation two-year training programme (FY1/FY2). The junior doctors interviewed identified a significant gap in their training on the topic of MUS, particularly in relation to their awareness of the topic, the appropriate level of investigations, possible psychological comorbidities, the formulation of suitable explanations for patients' symptoms and longer term management strategies. Many junior doctors expressed feelings of anxiety, frustration and a self-perceived lack of competency in this area, and spoke of over-investigating patients or avoiding patient contact altogether due to the challenging nature of MUS and a difficulty in managing the accompanying uncertainty. They also identified the negative attitudes of some senior clinicians and potential role models towards patients with MUS as a factor contributing to their own attitudes and management choices. Most reported a need for more training during the foundation years, and recommended interactive case-based group discussions with a focus on providing meaningful explanations to patients for their symptoms. There is an urgent need to improve postgraduate training about the topics of MUS and avoiding over-investigation, as current training does not equip junior doctors with the necessary knowledge and skills to effectively and confidently manage patients in these areas. Training needs to focus on practical skill development to increase clinical knowledge in areas such as delivering suitable explanations, and to incorporate individual management

Career progression during undergraduate and early postgraduate years is currently determined by successfully passing examinations. Both academic factors (secondary school examination results, learning style and training opportunities) and non-academic factors (maturity, ethnic origin, gender and motivation) have been identified as predicting examination outcome. Few studies have examined organization skills. Disorganized medical students are more likely to perform poorly in end-of-year examinations but this observation has not been examined in junior doctors. This study asked whether organization skills relate to examination outcome amongst junior doctors taking the clinical Part II examination for the Membership of the Royal College of Physicians (Practical Assessment of Clinical Examination Skills). The study was conducted prospectively at four consecutive clinical courses that provided clinical teaching and practice to prepare trainees for the examination. Arrival time at registration for the course was the chosen surrogate for organization skills. Trainees were advised that they should arrive promptly at 8.00 a.m. for registration and it was explained that the course would start at 8.30 a.m. Recorded arrival times were compared with the pass lists published by the Royal College of Physicians. The mean arrival time was 8.17 a.m. A total of 81 doctors (53.3%) passed the examination with a mean arrival time of 8.14 a.m. However, 71 doctors failed the exam and arrived, on average, six minutes later than doctors who passed (p?=?0.006). Better-prepared junior doctors were more likely to pass the final examination. Arriving on time represents a composite of several skills involved in the planning of appropriate travel arrangements and is therefore a valid marker of organization skills and preparation. This novel study has shown that good time-keeping skills are positively associated with examination outcome.

We recorded eye movements of eight elite junior basketball players. We hypothesized that a more stable gaze is correlated to a better shot rate. Upon preliminary testing we invited male juniors whose eyes could be reliably tracked in a game situation. To these ends, we used a head-mounted video-based eye tracker. The participants had no record of ocular or other health issues. No significant differences were found between shots made with and without the tracker cap, Paired samples t-test yielded p= .130 for the far and p=..900 > .050 for the middle range shots. The players made 40 shots from common far and middle range locations, 5 and 4 meters respectively for aged 14 years As expected, a statistical correlation was found between gaze fixation (in milliseconds) for the far and middle range shot rates, r=.782, p=.03. Notably, juniors who fixated longer before a shot had a more stable fixation or a lower gaze dispersion (in tracker's screen pixels), r=-.786, p=.02. This finding was augmented by the observation that the gaze dispersion while aiming at the basket was less (i.e., gaze more stable) in those who were more likely to score. We derived a regression equation linking fixation duration to shot success. We advocate infra-red eye tracking as a means to monitor player selection and training success.

The Santa Clara Valley is a long, narrow trough extending about 35 miles southeast from the southern end of San Francisco Bay where the regional alluvial-aquifer system has been a major source of water. Intensive agricultural and urban development throughout the 20th century and related ground-water development resulted in ground-water-level declines of more than 200 feet and land subsidence of as much as 12.7 feet between the early 1900s and the mid-1960s. Since the 1960s, Santa Clara Valley Water District has imported surface water to meet growing demands and reduce dependence on ground-water supplies. This importation of water has resulted in a sustained recovery of the ground-water flow system. To help support effective management of the ground-water resources, a regional ground-water/surface-water flow model was developed. This model simulates the flow of ground water and surface water, changes in ground-water storage, and related effects such as land subsidence. A numerical ground-water/surface-water flow model of the Santa Clara Valley subbasin of the Santa Clara Valley was developed as part of a cooperative investigation with the Santa Clara Valley Water District. The model better defines the geohydrologic framework of the regional flow system and better delineates the supply and demand components that affect the inflows to and outflows from the regional ground-water flow system. Development of the model includes revisions to the previous ground-water flow model that upgraded the temporal and spatial discretization, added source-specific inflows and outflows, simulated additional flow features such as land subsidence and multi-aquifer wellbore flow, and extended the period of simulation through September 1999. The transient-state model was calibrated to historical surface-water and ground-water data for the period 197099 and to historical subsidence for the period 198399. The regional ground-water flow system consists of multiple aquifers that are grouped

2012-01-01

Leptophis santamartensis, known only from Sierra Nevada de Santa Marta, Colombia, is one of the more poorly known species of the genus Leptophis. The characters used for its diagnosis largely overlap with those of other Leptophis, mainly with Leptophis ahaetulla occidentalis, the only other Leptophis known to occur in the Sierra Nevada de Santa Marta. A detailed comparison of L. a. occidentalis with the two known specimens of L. santamartensis leads to the conclusion that the latter should be relegated to the synonymy of the former.

Kelly, B.S.; Rainford, L.A.; Gray, J.; McEntee, M.F.

2012-01-01

Rationale and Objectives: In Emergency Departments (ED) junior doctors regularly make diagnostic decisions based on radiographic images. This study investigates whether collaboration between junior doctors and radiographers impacts on diagnostic accuracy. Materials and Methods: Research was carried out in the ED of a university teaching hospital and included 10 pairs of participants. Radiographers and junior doctors were shown 42 wrist radiographs and 40 CT Brains and were asked for their level of confidence of the presence or absence of distal radius fractures or fresh intracranial bleeds respectively using ViewDEX software, first working alone and then in pairs. Receiver Operating Characteristic was used to analyze performance. Results were compared using one-way analysis of variance. Results: The results showed statistically significant improvements in the Area Under the Curve (AUC) of the junior doctors when working with the radiographers for both sets of images (wrist and CT) treated as random readers and cases (p ≤ 0.008 and p ≤ 0.0026 respectively). While the radiographers’ results saw no significant changes, their mean Az values did show an increasing trend when working in collaboration. Conclusion: Improvement in performance of junior doctors following collaboration strongly suggests changes in the potential to improve accuracy of patient diagnosis and therefore patient care. Further training for junior doctors in the interpretation of diagnostic images should also be considered. Decision making of junior doctors was positively impacted on after introducing the opinion of a radiographer. Collaboration exceeds the sum of the parts; the two professions are better together.

An important factor while developing efficient doping prevention strategies is to identify relevant target groups, to evaluate the state of knowledge about this topic as well as to evaluate motivations behind using prohibited substances. Measures to prevent doping substances abuse have to be supported in early stages of childhood. The aim of this prospective study was to evaluate the knowledge of Tyrolean junior athletes about doping in sport. Next to the knowledge, their attitudes in regard to doping practices have also been a focus of this project. Within a prospective cross-sectional study, Tyrolean junior athletes aged between 14 and 19 years (n = 408) were anonymously questioned by distributing questionnaires in three Tyrolean sport schools as well as two Tyrolean sport-training centers. To collect the data, an anonymous questionnaire with close-ended questions was used. Next to sociodemographic data, questions also evaluated the knowledge about prohibited substances as well as attitudes and behaviors towards doping. The concept was set up based on contents of comparable studies and publications. The knowledge about doping among junior athletes was moderate. The consumer behavior of the young athletes on the other hand has turned out to be satisfactory. Nevertheless, the overall knowledge especially regarding potential negative side effects of doping agents is poor. To incorporate an effective doping-prevention strategy, improved education, particularly in terms of side effects, is clearly needed. To achieve sustainable doping-prevention effects, focus has to be generally set on education within the frame of junior competitive sport.

J Strength Cond Res 31(11): 3059-3066, 2017-The purpose of this study was to profile and compare anthropometric and physical capacities within elite junior and senior Australian football (AF) players of various chronological ages and stages of athletic development. Seventy-nine players, including junior and senior AF players from one professional club, were profiled using 11 assessments. Junior players were divided into 2 groups based on chronological age (under 16 and 18 years) and senior players according to years since drafted to a professional AF team (1-2 years, 3-7 years, and 8+ years). Parametric data were assessed using a 1-way analysis of variance (ANOVA), whereas nonparametric data were assessed using a Kruskal-Wallis ANOVA. The magnitude difference between players was measured using the Hopkins' effect size (ES). Significant differences were evident between under-16 players and all senior player groups for anthropometric (p = 0.001-0.019/ES = 1.25-2.13), absolute strength (p = 0.001-0.01/ES = 1.82-4.46), and relative strength (p = 0.001-0.027/ES = 0.84-3.55). The under-18 players displayed significantly lower absolute strength (p = 0.001-0.012/ES = 1.82-3.79) and relative strength (p = 0.001-0.027/ES = 0.85-4.00) compared with the 3-7 and 8+ players. Significant differences were evident between the under-16 players and senior player groups for explosive jumping and throwing tests (p = 0.001-0.017/ES = 1.03-2.99). Minimal differences were evident between all player groups for running assessments; however, the under-16 players were significantly slower compared with the 8+ players for the 3-km time trial (p senior AF players.

Which non-technical skills do junior doctors require to prescribe safely? A systematic review.

Dearden, Effie; Mellanby, Edward; Cameron, Helen; Harden, Jeni

2015-12-01

Prescribing errors are a major source of avoidable morbidity and mortality. Junior doctors write most in-hospital prescriptions and are the least experienced members of the healthcare team. This puts them at high risk of error and makes them attractive targets for interventions to improve prescription safety. Error analysis has shown a background of complex environments with multiple contributory conditions. Similar conditions in other high risk industries, such as aviation, have led to an increased understanding of so-called human factors and the use of non-technical skills (NTS) training to try to reduce error. To date no research has examined the NTS required for safe prescribing. The aim of this review was to develop a prototype NTS taxonomy for safe prescribing, by junior doctors, in hospital settings. A systematic search identified 14 studies analyzing prescribing behaviours and errors by junior doctors. Framework analysis was used to extract data from the studies and identify behaviours related to categories of NTS that might be relevant to safe and effective prescribing performance by junior doctors. Categories were derived from existing literature and inductively from the data. A prototype taxonomy of relevant categories (situational awareness, decision making, communication and team working, and task management) and elements was constructed. This prototype will form the basis of future work to create a tool that can be used for training and assessment of medical students and junior doctors to reduce prescribing error in the future. © 2015 The British Pharmacological Society.

Professional approaches in clinical judgements among senior and junior doctors: implications for medical education

2009-05-01

Full Text Available Abstract Background Clinical experience has traditionally been highly valued in medical education and clinical healthcare. On account of its multi-faceted nature, clinical experience is mostly difficult to articulate, and is mainly expressed in clinical situations as professional approaches. Due to retirement, hospitals in Scandinavia will soon face a substantial decrease in the number of senior specialist doctors, and it has been discussed whether healthcare will suffer an immense loss of experienced-based knowledge when this senior group leaves the organization. Both senior specialists and junior colleagues are often involved in clinical education, but the way in which these two groups vary in professional approaches and contributions to clinical education has not been so well described. Cognitive psychology has contributed to the understanding of how experience may influence professional approaches, but such studies have not included the effect of differences in position and responsibilities that junior and senior doctors hold in clinical healthcare. In the light of the discussion above, it is essential to describe the professional approaches of senior doctors in relation to those of their junior colleagues. This study therefore aims to describe and compare the professional approaches of junior and senior doctors when making clinical judgements. Methods Critical incident technique was used in interviews with nine senior doctors and nine junior doctors in internal medicine. The interviews were subjected to qualitative content analysis. Result Senior and junior doctors expressed a variety of professional approaches in clinical judgement as follows: use of theoretical knowledge, use of prior experience of cases and courses of events, use of ethical and moral values, meeting and communicating with the patient, focusing on available information, relying on their own ability, getting support and guidance from others and being directed by the

This report presents the experimental data of RUN 914 conducted at the ROSA-III test facility. The facility is a volumetrically scaled (1/424) simulator for a BWR/6 with the electrically heated core, the break simulator and the scaled ECCS (emergency core cooling system). RUN 914 was a 100% split break test at the recirculation pump suction line with an assumption of HPCS diesel generator failure and conducted as one of the break area parameter tests. A peak cladding temperature (PCT) of 851 K was reached at 130 s after the break during the reflooding phase. Whole core was completely quenched by ECCS, and the effectiveness of ECCS was confirmed. The primary test results of RUN 914 are compared in this report with those of RUN 926, which was a 200 % double-ended break test. The initiation of core dryout in RUN 914 was almost the same as that in RUN 926. Duration of core dryourt was, however, longer in RUN 914 because of later actuation of ECCSs. PCT in RUN 914 was 67 K higher than that in RUN 926. (author)

Experiment on performance of upper head injection system with ROSA-II

International Nuclear Information System (INIS)

1976-09-01

Thermo-hydraulic behavior in the primary cooling system of a pressurized water reactor with an upper head injection system (UHI) in a postulated loss-of-coolant accident (LOCA) has been studied with ROSA-II test facility. Simulated UHI and internal structures of the pressure vessel were installed to the facility for the experiment. Nine maximum-sized double-ended break tests and one medium-sized split break test were performed for the cold-leg break condition. The results are as follows: (1) Fluid mixing in the upper head is not perfect. (2) Cold water injection into the steam or two-phase fluid causes violent depressurization due to the condensation. Flow pattern in the primary cooling system is largely influenced by the above two. (auth.)

Full Text Available Rosa chinensis var. spontanea, an endemic and endangered plant of China, is one of the key ancestors of modern roses and a source for famous traditional Chinese medicines against female diseases, such as irregular menses and dysmenorrhea. In this study, the complete chloroplast (cp genome of R. chinensis var. spontanea was sequenced, analyzed, and compared to congeneric species. The cp genome of R. chinensis var. spontanea is a typical quadripartite circular molecule of 156,590 bp in length, including one large single copy (LSC region of 85,910 bp and one small single copy (SSC region of 18,762 bp, separated by two inverted repeat (IR regions of 25,959 bp. The GC content of the whole genome is 37.2%, while that of LSC, SSC, and IR is 42.8%, 35.2% and 31.2%, respectively. The genome encodes 129 genes, including 84 protein-coding genes (PCGs, 37 transfer RNA (tRNA genes, and eight ribosomal RNA (rRNA genes. Seventeen genes in the IR regions were found to be duplicated. Thirty-three forward and five inverted repeats were detected in the cp genome of R. chinensis var. spontanea. The genome is rich in SSRs. In total, 85 SSRs were detected. A genome comparison revealed that IR contraction might be the reason for the relatively smaller cp genome size of R. chinensis var. spontanea compared to other congeneric species. Sequence analysis revealed that the LSC and SSC regions were more divergent than the IR regions within the genus Rosa and that a higher divergence occurred in non-coding regions than in coding regions. A phylogenetic analysis showed that the sampled species of the genus Rosa formed a monophyletic clade and that R. chinensis var. spontanea shared a more recent ancestor with R. lichiangensis of the section Synstylae than with R. odorata var. gigantea of the section Chinenses. This information will be useful for the conservation genetics of R. chinensis var. spontanea and for the phylogenetic study of the genus Rosa, and it might also

Rosa chinensis var. spontanea , an endemic and endangered plant of China, is one of the key ancestors of modern roses and a source for famous traditional Chinese medicines against female diseases, such as irregular menses and dysmenorrhea. In this study, the complete chloroplast (cp) genome of R. chinensis var. spontanea was sequenced, analyzed, and compared to congeneric species. The cp genome of R. chinensis var. spontanea is a typical quadripartite circular molecule of 156,590 bp in length, including one large single copy (LSC) region of 85,910 bp and one small single copy (SSC) region of 18,762 bp, separated by two inverted repeat (IR) regions of 25,959 bp. The GC content of the whole genome is 37.2%, while that of LSC, SSC, and IR is 42.8%, 35.2% and 31.2%, respectively. The genome encodes 129 genes, including 84 protein-coding genes (PCGs), 37 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. Seventeen genes in the IR regions were found to be duplicated. Thirty-three forward and five inverted repeats were detected in the cp genome of R. chinensis var. spontanea. The genome is rich in SSRs. In total, 85 SSRs were detected. A genome comparison revealed that IR contraction might be the reason for the relatively smaller cp genome size of R. chinensis var. spontanea compared to other congeneric species. Sequence analysis revealed that the LSC and SSC regions were more divergent than the IR regions within the genus Rosa and that a higher divergence occurred in non-coding regions than in coding regions. A phylogenetic analysis showed that the sampled species of the genus Rosa formed a monophyletic clade and that R. chinensis var. s pontanea shared a more recent ancestor with R. lichiangensis of the section Synstylae than with R. odorata var. gigantea of the section Chinenses . This information will be useful for the conservation genetics of R. chinensis var. spontanea and for the phylogenetic study of the genus Rosa , and it might also facilitate the

Contrasting Perspectives Of Junior versus Senior NASA ISS Flight Controllers On Leadership And Cultural Issues

NASA flight controllers have always worked in a very demanding environment, but the International Space Station (ISS) poses even more challenges than prior missions. A recent NASA/Ames survey by Parke and Orasanu of NASA/Johnson flight controllers uncovered concerns about communications problems between American personnel and their international counterparts. To better understand these problems, we interviewed 14 senior and 12 junior ISS flight controllers at NASA/Johnson about leadership and cultural challenges they face and strategies for addressing these challenges. The qualitative interview data were coded and tabulated. Here we present quantitative analyses testing for differences between junior and senior controllers. Based on nonparametric statistical tests comparing responses across groups, the senior controllers were significantly more aware of the impact of working in dispersed teams, the context of constant change, and the upcoming multilateral challenges, while junior controllers were more aware of language and cultural issues. We consider our findings in light of other studies of controllers and other known differences between senior and junior controllers. For example, the fact that senior controllers had their formative early experience controlling pre-ISS short-duration Shuttle missions seems to have both positive and negative aspects, which are supported by our data. Our findings may also reflect gender differences, but we cannot unconfound this effect in our data because all the senior respondents were males. Many of the junior-senior differences are not only due to elapsed time on the job, but also due to a cohort effect. The findings of this study should be used for training curricula tailored differently for junior and senior controllers.

Desastre y Memoria Material: La Inundacion 2003 de Santa Fe, Argentina

Full Text Available On April 29, 2003, a catastrophic flood occurred in the Argentina city of Santa Fe de la Vera Cruz. Soon, the disaster became a political issue, as they had made serious accusations against the authorities and decision makers regarding negligence, corruption and lack of disaster preparedness. A local protest movement emerged, claiming both the allocation of responsibilities and financial compensation for the losses suffered by the victims. This article analyses the role of material memory and oblivion on the post disaster scene, more specifically, how different social actors in Santa Fe used places and objects in the contentious making of a disaster memoryscape. The analysis is based on ethnography from transtemporal translocal and field research conducted in Santa Fe between 2004 and 2011, and applies anthropological and sociological theories of memory to analyse these processes. Resumen El 29 de abril de 2003, ocurrió la peor inundación catastrófica en la historia de la ciudad argentina de Santa Fe de la Vera Cruz. Al poco tiempo, el desastre se convirtió en una cuestión política, ya que se habían realizado graves acusaciones contra las autoridades y tomadores de decisiones con respecto a la negligencia, la corrupción y la falta de preparación para desastres. Surgió un movimiento de protesta demandando tanto la asignación de responsabilidades, como la compensación económica por las pérdidas sufridas por las víctimas. Este artículo analiza el papel de la memoria material y el olvido en el escenario del posdesastre, y más específicamente cómo los diferentes actores sociales en Santa Fe usaron los lugares y los objetos en una contienda por construir un memo-paisaje del desastre. El análisis se basa en etnografía de trabajo de campo translocal y transtemporal realizado en Santa Fe entre 2004 y 2011, y aplica las teorías antropológicas y sociológicas de la memoria a fines de analizar estos procesos.

When students proceed to junior high school from elementary school, rapid changes in the environment occur, which may cause various behavioral and emotional problems. However, the changes in cognitive functions during this transitional period have rarely been studied. In 158 elementary school students from 4th- to 6th-grades and 159 junior high school students from 7th- to 9th-grades, we assessed various cognitive functions, including motor processing, spatial construction ability, semantic fluency, immediate memory, delayed memory, spatial and non-spatial working memory, and selective, alternative, and divided attention. Our findings showed that performance on spatial and non-spatial working memory, alternative attention, divided attention, and semantic fluency tasks improved from elementary to junior high school. In particular, performance on alternative and divided attention tasks improved during the transitional period from elementary to junior high school. Our finding suggests that development of alternative and divided attention is of crucial importance in the transitional period from elementary to junior high school.

Full Text Available Findings about the relation between musculoskeletal injuries and training patterns in orienteering athletes are sparse. Therefore, the musculoskeletal injuries and training patterns of 31 Swiss elite orienteering athletes aged 18-19 years were analyzed in a retrospective study. Individual training diaries and medical records were used to assess training data and injury history, respectively. Group comparisons and a multiple linear regression (MLR were performed for statistical analysis. The junior elite orienteering athletes performed 7.38 ± 2.00 training sessions weekly, with a total duration of 455.75 ± 98.22 minutes. An injury incidence rate (IIR of 2.18 ± 2.13 injuries per 1000 hours of training was observed. The lower extremity was affected in 93% of all injuries, and the knee (33% was the most commonly injured location. The MLR revealed that gender and six training variables explained 60% of the variance in the injury severity index in this study. Supported by the low IIR in the observed age group, the training protocol of the junior elite orienteering athletes was generally adequate. In comparison to elite track, marathon, and orienteering athletes, the junior elite athletes performed less high-intensity interval training (HIIT. However, more frequent HIIT seems to be a protective factor against injuries.

2016-08-01

The grading of Australian junior and youth rugby union players has received substantial media attention in recent years. Media reports have focussed on size mismatches observed between players, especially players with Polynesian heritage, and the concerned parents who fear for the safety of their child owing to perceived mismatches. Although such concerns are well meaning, few media reports recognise the need for substantial evidence to determine the best grading system for junior and youth rugby union players. The current study reviewed relevant literature pertinent to the grading and dispensation of junior and youth rugby union players. Using primary and secondary search strategies, a total of 33 articles reporting the anthropometric characteristics of junior and youth rugby players were identified. Anthropometric data from the literature were compared with normative population data and currently used dispensation criteria. Junior and youth rugby players were found to be taller and heavier than normative population data. Current dispensation criteria, in terms of body mass, were found to vary and it is suggested that criteria be revised and standardised across rugby unions throughout Australia. Although it is acknowledged that other factors are important for grading players, anthropometric characteristics should be considered as potential dispensation criteria to supplement current age-based grading for junior and youth rugby union players. Measuring the body mass and stature of each junior player upon pre-season registration is suggested, which would provide data to establish valid dispensation criteria for the following season.

Objectives: To evaluate the impact of a computer-aided detection (CAD) system on the ability of a junior and senior radiologist to detect breast cancers on mammograms, and to determine the potential of CAD as a teaching tool in mammography. Methods: Hundred biopsy-proven cancers and 100 normal mammograms were randomly analyzed by a CAD system. The sensitivity (Se) and specificity (Sp) of the CAD system were calculated. In the second phase, to simulate daily practice, 110 mammograms (97 normal or with benign lesions, and 13 cancers) were examined independently by a junior and a senior radiologist, with and without CAD. Interpretations were standardized according to BI-RADS classification. Sensitivity, Specificity, positive and negative predictive values (PPV, NPV) were calculated for each session. Results: For the senior radiologist, Se slightly improved from 76.9 to 84.6% after CAD analysis (NS) (one case of clustered microcalcifications case overlooked by the senior radiologist was detected by CAD). Sp, PPV and PNV did not change significantly. For the junior radiologist, Se improved from 61.9 to 84.6% (significant change). Three cancers overlooked by the junior radiologist were detected by CAD. Sp was unchanged. Conclusion: CAD mammography proved more useful for the junior than for the senior radiologist, improving sensitivity. The CAD system may represent a useful educational tool for mammography

Ling, Ji Min; Lim, Kim Zhuan; Ng, Wai Hoe

2012-02-01

Multimedia Messaging Service (MMS) is used by neurosurgical residents to transmit scan images to the attending neurosurgeon in conjunction with telephone consultation. This service has been well received by the attending neurosurgeons, who felt that after viewing scan images on their phones, they felt increased confidence in clinical decision making and that it reduced the need for recall to the hospital. The use of MMS can be extended to junior doctors making referrals from regional hospitals with no neurosurgical cover. This study aims to validate the competency of non-neurosurgically trained junior doctors in selecting optimal images to transmit via MMS to the attending neurosurgeon on call. Ten junior doctors with no formal neurosurgical training and five neurosurgical residents were interviewed. They were shown the full complement of images together with relevant clinical history and assessment. They were then asked to make the radiological diagnosis and then select two images for MMS transmission to the attending neurosurgeon that they thought would best aid the neurosurgeon in clinical decision making. The attending neurosurgeon was asked to comment, on each image, whether his management plan would differ if he was shown the entire series of the images. All the images chosen are deemed appropriate, and the decision made based on the MMS images would be similar if the entire series of images were available to the neurosurgeon. However, 7 of 10 junior doctors were unable to read magnetic resonance images of lumbar spine. There was no significant difference in the images chosen by the neurosurgical residents and the junior doctors. It is feasible and safe for junior doctors to utilize MMS to transmit computed tomographic images to a neurosurgeon while making an urgent referral. The images selected are representative of the disease pathology and facilitate clinical decision making. Copyright © 2012 Elsevier Inc. All rights reserved.

From Argentin lake, at west on Andean hills, to Puerto Santa Cruz on Atlantic coast, Santa Cruz river cross eastward Santa Cruz province over 250 km in Patagonia at southern Argentina. Present bed of the river has a meandering outline with first order meanders of great ratio bends and second order meanders of minor ratio bends. Principal wanderings are 45 to 55 km spaced from near Estancia La Julia or Rio Bote at west to Comandante Luis Piedrabuena at east. On river's bed middle sector these great curvatures are located at Estancia Condor Cliff and Estancia Rincon Grande. Regional and partial detailed studies allow to recognize structural control on river's bed sketch and valley s geomorphology that relates first order bends with reactivated principal faults. These faults fit well with parallel system of northwest strike of Austral Basin.On geological, geomorphologic and structural evidences recognized in Santa Cruz river, quaternary tectonic activity, related to Andean movements in southern Patagonian foreland, is postulated.

Full Text Available La evaluación del aprendizaje es uno de los aspectos de mayor importancia en la formación integral del estudiante; pues, no todos los docentes están dispuestos a reconocer  insuficiencias conceptuales y limitaciones al evaluar debido a la falta y/o debilidad del soporte teórico y pedagógico. El objetivo de la presente investigación fue determinar la diferencia del conocimiento sobre evaluación del aprendizaje en los docentes de secundaria de las I. E. Rosa Agustina Donayre de Morey y República de Venezuela de Iquitos en el año 2011. El trabajo fue de tipo descriptivo-comparativo, cuya población fue de 103  y 61 docentes respectivamente, las muestras seleccionadas aleatoriamente fueron del 50% de docentes de las I. E “Rosa Agustina Donayre de Morey” y “República de Venezuela” respectivamente. Los resultados indican que X2c = 2.76, X2t = 12.59,  X2t ≠ X2c, gl = 6, ∞ = 0.05% aceptando la hipótesis de investigación: Existiría estadísticamente diferencia entre el conocimiento sobre evaluación del aprendizaje en los docentes de secundaria de las I. E. Rosa Agustina Donayre de Morey y República de Venezuela.

Full Text Available The deleterious effects of Mn stress on many species have been studied, mainly concerning biochemical, physiological and growth parameters of plants. However, there are few studies relating the anatomical and ultrastructural changes in response to manganese (Mn nutritional disorders, This study examined the leaf ultrastructure of Mn-inefficient (IAC-15, Santa Rosa and Mn-efficient (IAC-Foscarin 31 soybean (Glycine max L. genotypes in response to three rates of Mn (0.5, 2 and 200 µmol L-1 in the nutrient solution. Symptoms of Mn deficiency developed 12 days after transplanting in IAC-15 and Santa Rosa, followed by IAC-Foscarin 31 on the 15th day. Only IAC-15 and Santa Rosa leaves showed symptoms of Mn toxicity. The Mn concentration in leaves ranged from 8.6 (deficiency to 886.3 mg kg-1 d.w. (toxicity. There were no changes either in stomata length or stomata number per unit of leaf surface. Cytoplasm disorganization was observed in IAC-15 under Mn-excess. In this case, the cytoplasm was amorphous, densely stained and extensively disorganized, with increased vacuolation. Mn effects were not found in mitochondria and nucleus in any of the genotypes tested. Under all Mn concentrations, many lipid globules were observed in the IAC15 chloroplasts. There was an increase in the number of plastids as well as in the size of starch grains within IAC-Foscarin 31 chloroplasts as Mn concentration in the nutrient solution increased. Genotypes had marked differences in the ultrastructure organization, mainly in leaf chloroplasts grown under conditions of both Mn deficiency and toxicity (the most sensitive genotype was IAC-15.Os efeitos negativos provocados tanto pela deficiência quanto pela toxidez de manganês (Mn no desenvolvimento das plantas têm sido avaliados, considerando-se os aspectos bioquímicos e produtivos da parte aérea, particularmente, onde os sintomas visuais são manifestados. Entretanto, há poucas informações na literatura abordando as
