Major ion chemistry of snow cores along a transect in central Dronning Maud Land, Antarctica

Among the large variety of particulates in the atmosphere, calcic mineral dust particles have highly reactive surfaces that undergo heterogeneous reactions with nitrogen oxides contiguously. The association between Ca2+, an important proxy indicator of mineral dust and NO3-, a dominant anion in the Antarctic snow pack was analysed. A total of 41 snow cores (~ 1 m each) that represent snow deposited during 2008-2009 were studied along coastal-inland transects from two different regions - the Princess Elizabeth Land (PEL) and central Dronning Maud Land (cDML) in East Antarctica. Correlation statistics showed a strong association (at 99 % significance level) between NO3- and Ca2+ at the near-coastal sections of both PEL (r = 0.72) and cDML (r = 0.76) transects. Similarly, a strong association between these ions was also observed in snow deposits at the inland sections of PEL (r = 0.8) and cDML (r = 0.85). Such systematic associations between Ca2+ and NO3- is attributed to the interaction between calcic mineral dust and nitrogen oxides in the atmosphere, leading to the possible formation of calcium nitrate (Ca(NO3)2). Forward and back trajectory analyses using HYSPLIT model v. 4 revealed that Southern South America (SSA) was an important dust emitting source to the study region, aided by the westerlies. Particle size distribution showed that over 90 % of the dust was in the range < 4 µm, indicating that these dust particles reached the Antarctic region via long range transport from the SSA region. We propose that the association between Ca2+ and NO3- occurs during the long range transport due to the formation of Ca(NO3)2. The Ca(NO3)2 thus formed in the atmosphere undergo deposition over Antarctica under the influence of anticyclonic polar easterlies. However, influence of local dust sources from the nunataks in cDML evidently mask such association in the mountainous region. The study indicates that the input of dust-bound NO3- may contribute a significant fraction of the total NO3- deposited in Antarctic snow.

Sydenham Street Revived: A Public Space Experiment

In 2015, the Sydenham Street Revived pop-up park project (SSR) transformed Sydenham Street between Princess and Queen Streets into a temporary pedestrian-only public space. The goal of the project was to test out the idea of permanently pedestrianizing this street section. But what did this urban experiment ultimately prove? Using video footage, photographs, and observations recorded before and during the project, this report analyzes the use of the space in order to evaluate the claim that SSR created a successful public space and to make recommendations for a permanent public space on Sydenham Street. Two research methods were used: quantitative data collection, consisting of headcounts of both pedestrians and stationary users of the space; and a qualitative observational survey, based on the criteria for successful public spaces developed by the Project for Public Spaces. Data collection occurred two days one week prior to the project, and two days during the project, on days that were similar in terms of temperature and weather. The research revealed that the SSR did create a successful public space, although additional research is needed in order to determine how the space would function as a public place throughout different seasons, to study the street closure’s impact on surrounding residents and businesses, and to understand how private commercial activity would influence use. Recommendations for a permanent public space on Sydenham Street include considerations for flexible street design and a continuous, barrier-free surface; ensuring that there is an abundance of places to sit; making opportunities for public and community-created art; and to improve walkability by connecting the grid using a mid-block walkway.

Diplomacia y misión en Europa durante la Guerra de Sucesión: los Habsburgo- Wolfenbüttel, el estado de Milán y el catolicismo septentrional

Las perspectivas geopolíticas de la guerra de Sucesion espanola traspasaron ampliamente los limites de la herencia territorial de Carlos II. El político enlace del candidato austriaco al trono de Madrid, Carlos III de Austria, con Isabel Cristina de Braunschweig-Wolfenbuttel, una princesa luterana convertida ex profeso al catolicismo, vinculó las dos dinastias con el esfuerzo misionero de la Santa Sede en el norte del Sacro Imperio. En el presente estudio se propone reconstruir la relacion de la red diplomatica Wolfenbuttel con el papado y la monarquia carolina, ademas de apuntar la difusa -pero constante- presencia de la soberana dentro del proceso de financiación lombarda del misionalismo germánico a comienzos del Setecientos.

National Cancer Strategy 2006: a Strategy for Cancer Control in Ireland – Evaluation Panel Report

Review of ‘A Strategy for Cancer Control in Ireland’. The review was led by Professor Pádraig Warde of the Princess Margaret Cancer Centre, Toronto.  The evaluation panel was very impressed with the excellent progress in the cancer control system in Ireland since the publication of “A Strategy for Cancer Control in Ireland” in 2006.   Download the report here.

Silagem do bagaço de sorgo sacarino

Brazilian sweet sorghum is used to generate ethanol and the bagasse is burned in industrial boilers or deposited on soil polluting the environment. This study evaluated the performance of sorghum plants and its bagasse silage nutritional value aiming to use it in the ruminant nutrition. Experiments were set up on the UTFPR campus at Dois Vizinhos-PR. The first trial was established on October 2nd, 2012 using the genotypes ADV 2010, Hunnigreen, Sugargraze, Volumax, BR 505, 503, 501 and the second trial at 2013 on November 27th assessing the materials ADV 2010, Sugargraze, Hunnigreen, EX 5110, BR 506, 508, 509 and 511. Experimental was laid out as a randomized block design with three replications. Results were analyzed through ANOVA comparing the averages by Duncan test at 5% error probability. As field variables were evaluated: plant height (Pl hei), green mass production (GM Prod), percentage of leaves, stems and panicles in relation to the plant, stems production without straw (Prod stems with straw), whole stems production (Who stems Prod), stem diameter (Stem diam), juice production (Juice prod) and Brix degree (oBrix). After juice plant extraction, forage bagasse was crushed and packed in silos for 60 days and green matter yield was estimated (GM). In bagasse silage gauged to buffer capacity (BC), dry matter (DM), mineral matter (MM), crude protein (CP), ether extract (EE), total carbohydrates (TC), non-fibrous carbohydrates (NFCH), neutral detergent fiber (NDF), acid detergent fiber (ADF), lignin (LIG ) and digestibility "in vitro" (DIGIV). There was no significant difference (P> 0.05) between genotypes regarding to green matter production and on average, the second crop yield was lower and reflected in the reduction of bagasse production. Bagasse silage DM was of 32.3% and 33.1%; NDF 73% and 65.8%, crude protein 3.8% and 5.9; pH 3.7 and 3.7; TC and 9.8 and 10.7. mg MS-1; the amount of NFCH was 11.1 and 13.5%; DIG of DM 36.9 and 62.4% for the respectively to the bagasse produced from materials grown in the 2012/2013 and 2013/2014 seasons. Hybrid genotypes had a better agronomic performance while the varieties were more efficient in bromatological indexes. And despite the high percentage of NDF and the low protein level, it is possible to feed ruminants with this coproduct.

Princesses et duchesses bibliophiles à la cour de René d'Anjou

De nombreuses dames de la cour d'Anjou ont exercé un mécénat littéraire et bibliophilique important à la cour d'Anjou. Parmi elles se trouvent Marie de Blois (v. 1340-1404), Yolande d'Aragon (1381-1442), Isabelle de Lorraine (v. 1400-1453), Jeanne de Laval (1433-1498) et Marie de Clèves (1426-1487). Le mécénat de ces femmes, parentes, épouses ou amies de René d'Anjou, est ici abordé à travers les documents d'archives et les manuscrits conservés qui attestent d'un intérêtréel et constant pour l'art du livre et de l'enluminure et pour la littérature en vogue à la cour. Une attention toute particulière est réservée au Pèlerinage de Vie humaine de Guillaume de Digulleville dont la version rimée, et plus tard la version en prose commandée par Jeanne de Laval, n'a cessé de captiver le lectorat féminin et notamment Marguerite d'Anjou, Blanche d'Anjou et Guyonne de Beauvau
