Abstract
We present the discovery of the giant planet KELT-19Ab, which transits the moderately bright (

) A8V star TYC 764-1494-1 with an orbital period of 4.61 days. We confirm the planetary nature of the companion via a combination of radial velocities, which limit the mass to

(

), and a clear Doppler tomography signal, which indicates a retrograde projected spin–orbit misalignment of

degrees. Global modeling indicates that the

K host star has

and

. The planet has a radius of

and receives a stellar insolation flux of

, leading to an inferred equilibrium temperature of

K assuming zero albedo and complete heat redistribution. With a

, the host is relatively slowly rotating compared to other stars with similar effective temperatures, and it appears to be enhanced in metallic elements but deficient in calcium, suggesting that it is likely an Am star. KELT-19A would be the first detection of an Am host of a transiting planet of which we are aware. Adaptive optics observations of the system reveal the existence of a companion with late-G9V/early-K1V spectral type at a projected separation of

. Radial velocity measurements indicate that this companion is bound. Most Am stars are known to have stellar companions, which are often invoked to explain the relatively slow rotation of the primary. In this case, the stellar companion is unlikely to have caused the tidal braking of the primary. However, it may have emplaced the transiting planetary companion via the Kozai–Lidov mechanism.

Published: December 2017

Objectives
The aim of this study was to compare the shear bond strength (SBS) of brackets systems with four different base technologies.

Materials and Methods
Maxillary first premolars were randomly divided into four groups of thirty specimens each: (1) Master Series™ conventional twin, (2) T3™ self-ligating, (3) Victory series™ conventional twin, and (4) H4™ self-ligating brackets. Maxillary first premolars were bracketed using an acid-etch composite system, and the SBS measured using an Instron Universal Testing Machine at a crosshead speed of 2 mm/min. The ANOVA and Tukey’s multiple comparison tests were performed with significance predetermined at P ≤ 0.05.

Results
The overall mean bond strengths were 8.49 ± 2.93, 10.85 ± 3.34, 9.42 ± 2.97, and 9.73 ± 2.62 for the Groups 1, 2, 3, and 4 brackets, respectively. One-way ANOVA test gave an F = 3.182 with a P = 0.026. The Group 1 and Group 2 were observed to have statistically significant difference with a P = 0.014.

Conclusions
The T3 self-ligating one-piece design with microetched Quadra Grip™ base brackets had the highest bond strength. The SBS difference between Group 2, Group 3, and Group 4 was not significant, but the difference between Group 2 and Group 1 was statistically significant.

Abstract. The Mediterranean region is a climate hot spot, sensitive not only to global warming but also to water availability. In this work we document major temperature and precipitation changes in the Iberian Peninsula and margin during the last 2000 years and propose an interplay of the North Atlantic internal variability with the three atmospheric circulation modes (ACMs), (North Atlantic Oscillation (NAO), east atlantic (EA) and Scandinavia (SCAND)) to explain the detected climate variability. We present reconstructions of sea surface temperature (SST derived from alkenones) and on-land precipitation (estimated from higher plant n-alkanes and pollen data) in sedimentary sequences recovered along the Iberian Margin between the south of Portugal (Algarve) and the northwest of Spain (Galiza) (36 to 42° N). A clear long-term cooling trend, from 0 CE to the beginning of the 20th century, emerges in all SST records and is considered to be a reflection of the decrease in the Northern Hemisphere summer insolation that began after the Holocene optimum. Multi-decadal/centennial SST variability follows other records from Spain, Europe and the Northern Hemisphere. Warm SSTs throughout the first 1300 years encompass the Roman period (RP), the Dark Ages (DA) and the Medieval Climate Anomaly (MCA). A cooling initiated at 1300 CE leads to 4 centuries of colder SSTs contemporary with the Little Ice Age (LIA), while a climate warming at 1800 CE marks the beginning of the modern/Industrial Era. Novel results include two distinct phases in the MCA: an early period (900–1100 years) characterized by intense precipitation/flooding and warm winters but a cooler spring–fall season attributed to the interplay of internal oceanic variability with a positive phase in the three modes of atmospheric circulation (NAO, EA and SCAND). The late MCA is marked by cooler and relatively drier winters and a warmer spring–fall season consistent with a shift to a negative mode of the SCAND. The Industrial Era reveals a clear difference between the NW Iberia and the Algarve records. While off NW Iberia variability is low, the Algarve shows large-amplitude decadal variability with an inverse relationship between SST and river input. Such conditions suggest a shift in the EA mode, from negative between 1900 and 1970 CE to positive after 1970, while NAO and SCAND remain in a positive phase. The particularly noticeable rise in SST at the Algarve site by the mid-20th century (±1970), provides evidence for a regional response to the ongoing climate warming. The reported findings have implications for decadal-scale predictions of future climate change in the Iberian Peninsula.
Max Scheler: educar é humanizar
Authors: Schulz Almiro 
Published: December 2017

A educação foi e é objeto de estudo, de análise, de reflexão e de interesse de agentes de múltiplos setores e áreas de saberes, seja no âmbito das políticas públicas, da economia, seja no acadêmico, em especial, das áreas de sociologia, história, psicologia e filosofia. Este artigo tem por objetivo apresentar um aspecto central da visão
da filosofia da educação de Max Scheler, segundo o qual educar significa humanizar. O texto é resultado de um projeto de pesquisa sobre Max Scheler, com base em uma revisão bibliográfica de textos primários e de comentadores. Mesmo que Scheler não tivesse a educação como problema originário de seus estudos e pesquisas, pois é mais conhecido por suas preocupações e elaborações no campo da ética, em especial sobre os valores, ele desenvolveu um sistema axiológico; tratou da filosofia da religião; e, posteriormente, voltou-se para a antropologia
filosófica. Essas questões acabaram gerando a necessidade de inserir em suas abordagens e discussões a educação como processo de humanização, que é uma de suas concepções-chave na visão educativa. Parte, portanto, de uma antropologia, tendo como ponto central a indagação: quem é o homem? Humanizar significa desenvolver o espírito, o que é peculiar ao homem e distingue-o dos outros seres vivos. É um processo, um vir a ser, um ir e vir, um avançar e retroceder. Educar é humanizar.

ABSTRACT (no. 2017-095)
In 2012, the International Association of Oil and Gas Producers initiated “The Arctic Oil Spill Response Technology Joint Industry Program (JIP)” with nine companies funding projects in a wide range of technical areas. This paper summarizes results from the project “Dispersant Testing under Realistic Conditions”, a collaboration between SINTEF (Norway) and SL Ross (Canada). The objective of the research was to build on current knowledge to increase understanding of the effect of oil type, degree of weathering, and environmental conditions on dispersant effectiveness in ice-covered waters.
SINTEF and SL Ross performed approximately 70 tests using two identical recirculating flumes with variable parameters such as oil types, dispersant type, mixing energy, ice coverage, and water salinity. The oils were weathered in the flumes for 6 or 18 hours under simulated winds, waves, and cold temperatures to represent weathering that might occur at sea prior to dispersant application. The dispersed oil was exposed to various mixing energies, starting with low energy waves, followed by somewhat higher energy waves, and finally by applying propeller wash. Four crude oils were studied and the dispersant efficiency of three commercial oil spill dispersants were evaluated for the tested oils. Other test parameters were ice coverage (50% and 80%) and water salinity (35, 15, and 5 ppt).
Dispersant effectiveness as a function of the different test variables were estimated using results from the flume-based experiments. As expected, shorter weathering times resulted in an increase in dispersant efficiency. The dispersant effectiveness varied with both oil type and dispersant type applied, and the effectiveness increased when higher mixing energy conditions were used. Varying the ice cover did not influence the results significantly, but water salinity did, with the lowest dispersant efficiencies found at 5 ppt salinity.
The conclusions are based on the findings from testing performed under the controlled conditions and may not be directly transferable to all conditions that could be encountered in the Arctic. However, this study shows that dispersants can be considered as a response option for spills in ice, but effectiveness needs to be validated in the field during an actual event.
Managing human risk during an oiled wildlife response
Authors: Short Michael 
Published: December 2017

ABSTRACT 2017-066
Human risks during an oiled wildlife response (OWR) can be divided principally amongst physical, chemical and biological hazards. This paper identifies the risks associated with these hazards to oiled wildlife responders, other responders and the general public. Hazards and risks are managed by specific risk management procedures. These commonly include identifying individual steps in the activity, identifying associated hazards and risks, quantifying the risks and then applying treatments and controls to eliminate or reduce risk exposure to an acceptable level. For treatments and controls to manage risks effectively these are applied as a part of pre-incident contingency planning, during incidents and post incidents. Treatments and controls identified in the paper include responder training, registration of personnel, incident planning, use of safety data sheet recommendations, personal protection equipment, minimising exposure times, applying call in procedures and communication systems, making available emergency supportive equipment, providing food and fluids, vaccinations for responders, applying dangerous wildlife risk reduction practices, safe manual handling and transportation practices, safe motor driving and vessel handling practices, fatigue management practices, working in pairs as a minimum requirement, safety precautions when working near water and at industrial sites, equipment maintenance and safe use, safe practices around sharps, compliant waste disposal practices, reporting mechanisms for near misses and injuries and the systems to prevent their re-occurrence. Mental health hazards during incidents and post incident phases are also a key feature to manage and are often overlooked. Risks associated with mental health include stress and trauma. Supportive treatments and controls include response planning, professional counselling and medical support. The information to develop this paper was taken from a range of international responses.

ABSTRACT
Research on the fate and effects of herding agents used to contain and thicken oil slicks for in situ burning in Arctic waters continues under the auspices of the International Association of Oil and Gas Producers Arctic Oil Spill Response Technology – Joint Industry Program (JIP). In 2014/2015 laboratory studies were conducted on the fate and effects of herders. The purpose of the studies was to improve the knowledge base used to evaluate the environmental risk of using herders in connection with in situ burning for oil spill response in Arctic seas. Two herding agents were studied (OP 40 and ThickSlick 6535).
Laboratory-scale herding and burning experiments were carried out for investigating the physical fate of the two herders during combustion of Alaska North Slope and Grane crude oils (fresh and emulsified). The results showed that after burning, the herder was mainly found on the water surface, and only small concentrations of herders were found in the water column (0.2–22.8 mg/L).
The inherent properties of herders in relation to toxicity and bioaccumulation on the high Arctic copepods (Calanus hyperboreus), as well as the biodegradability of herders were studied under arctic conditions. The results indicated that a distinct mortality was seen at the highest test concentrations of the herders. However, the concentration of herders required to produce acute toxicity in the laboratory was approximately three orders of magnitude higher than the concentrations measured in the water column when herders were used to conduct an in situ burn in the laboratory. OP-40 might bio-accumulate whereas TS6535 might not. TS6535 was mostly degraded within 7 days, whereas the degradation of OP-40 was insignificant over 28 days.
Since herders are mainly considered as a surface active chemical compound, the potential impacts of herders on Arctic seabird feathers (from legally hunted Thick-Billed Murre and Common Eider) were investigated. Different dosages of herders were tested; high dosages that might be present just after the application of the herder and low dosages (approximately monolayers) likely to occur for a significant time and distance from the operations. Low dosages corresponding to approximately monolayers of OP-40 and TS6535 did not cause feathers to sink; however they did absorb more water than the controls. The high dosages caused measured damages to the feather microstructure.
Finally, laboratory burning experiments were carried out to determine if there was a difference in the composition of smoke plumes from mechanically contained burns versus herded oil burns. Herder was not measured in the smoke plumes, and there were no other noticeable differences in combustion between the two methods of containment (herder vs. metal ring).
