Pedro Bank is about 1,300 square miles in extent and lies at the mouth of the Palk Strait close to the mainland, enabling smaller boats to exploit it. Trawl surveys indicated the presence of substantial demersal varieties on the Pedro Bank, but the results of the early commercial operations indicate that a 135-foot trawler may not be operated continuously on the bank without diminishing returns. Subsequent to the commercial operations extensive surveys with smaller boats and various types of gear were carried out. Of the various types of gear tried out, results from bottom long lining and hand lining operations were promising. Trials were carried out to compare these two types of gear. Though not extensive, these trials indicated that at the initial stages of exploitation of the Bank, hand lining, which is extensively practiced in Ceylon, may be better but as exploitation progresses; with more experience, it should be possible to overcome some of the present disadvantages of bottom long lining and eventually bottom long lining should produce better results. The recently introduced mechanised craft are exploiting only the fringe of the bank and it should be possible to exploit its stocks fully with slightly bigger boats with a 35-40 mile range.

Sri Lanka's interest in trawler fishing dates back to 1902 when a Colombo merchant attempted to operate a trawler off Sri Lanka's waters. The next attempt was made in 1907. These attempts did not proceed any further. Between 1920 and 1923 a very comprehensive survey of the littoral waters around the island was carried out. One of the principal aims of the survey was to investigate the possibility of trawler fishing in the seas around. Malpas (1926) and Pearson and Malpas (1926) reporting the results of the survey indicated that the Wadge and Pedro banks were the only areas available for commercial trawler operations and indicated that the fish resources in the two banks could be profitably exploited. Commercial exploitation of the Wadge bank commenced in 1928 and a fishery is now firmly established in the bank. The Marine Biologist and the Director of fisheries in their administration reports and Sivalingam and Medcof (1957) and the author (1965) have reported on the progress of the Wadge bank fishery. Some of the trends indicated by an analysis of the records of the commercial trawling operations are further discussed in this paper.

A Embrapa Acre iniciou, em meados de 1995, um projeto de manejo florestal sustentado para pequenas propriedades, tendo como principal característica a prescrição de uma intervenção de baixo impacto sobre a floresta por meio de "métodos artesanais" de exploração de madeira. Estes métodos consideram os poucos recursos materiais de que dispõem os pequenos produtores.

In the wake of the latest news regarding IPB’s award for best Polytechnic Institute in Portugal, we would like to congratulate the IPB community who has always striven for the quality of the institution within the national and international academic milieu. We are, undoubtedly, bowled over by the 1st place in the national context (out of the 27 national institutions under evaluation) and the 7th position in the international scope. In fact, it is worth mentioning that the IPB has won this award, three years in a row, being in a leading position in the ranking promoted and sponsored by the European Union. This year’s edition has selected and evaluated over 1300 world higher education institutions. Teaching Crossroads intends thus to give a watershed contribution to the IPB’s successful and most valued pathway. Numbers indicate that Teaching Crossroads has had over 2550 downloads since it first came out. But let’s cut to the chase. Once again, we are delighted to present the 5th number of Teaching Crossroads. This wholly calculated and well-sustained editorial adventure started in 2012 when the first number of Teaching Crossroads first saw the light. This year’s publication includes the areas of Human Geography/anthropology, Information Technology and Forensics and Language and culture, focusing on minority languages. Alongside this, as in the two last previous numbers, we’ve included the specific area for International mobility, Intensive Programmes and Erasmus+ Mobility of Individuals, being the latter financed by the European Union within the Erasmus+ Programme, whereas the former is sponsored uniquely by the foreign partner institution, in this case, Lillebaelt Academy in Denmark. These types of programmes convey very positive and overarching ideas, resonant in cross-cultural and educational benefits, valuable for all the involved partners. We would very kindheartedly like to thank the authors for having contributed with much enlightening and serious articles on a wide array of areas. Pablo M. Orduna Pórtus’s article focuses on border culture and heritage management. The author’s study is placed on two borderlands of the Iberian Peninsula: Roncal Valley (Navarre) and Riverbanks of Douro. Going beyond the linear or physical conception of the border, the author centres his study on the metaphysical and symbolic ideas of the frontier that sustain his anthropological analysis. Michal Popdora manages to find evidence for his proposal of a new conception of teaching Image Processing, based on the student-centered approach. A hands-on experience on a Project-based Learning methodology sustains the teaching project. Grounded on “a forensic-flavored style”, using the author’s own words, he shows how students can become engaged in a highly effective learning process. Cláudia Martins is already a confirmed habitué of this publication, as in every Erasmus Week she delivers a lecture on Portuguese language and culture to visiting teaching and non-teaching staff. This time, the author decided to delve into a Portugal’s official language, Mirandese, spoken in a small designated area in the northeastern part of Portugal, Miranda do Douro and its surrounding area. The author gives account of some thought-provoking facts about the language, from the origin and the survival of the language, however still a minority language, up to the moment when it was acknowledged Portugal’s second official language, together with the challenges that nowadays faces. Luís Frölen Ribeiro, João Eduardo Ribeiro, Carlos Casimiro Costa, António Duarte, Carlos Andrade from the Polytechnic Institute and Arne Svinth, John Madsen, Morten Thomsen, Kent Smidstrup, Carsten John Jacobsen from the Lillebaelt Academy, in Denmark, participate in a joint project which they describe, outlining the main goals and gains of the project. To overcome teaching difficulties regarding the engineering degrees, a 12-ECTS joint course from Lillebaelt Academy and Polytechnic Institute of Bragança was created based on the Danish model. The course Product Development and Industrial Processing was hence created. Rui Pedro Lopes presents an insightful and acute account of the Internationalization programmes in Higher Education in Europe. At one go, the author describes his own experience as a visiting lecturer, within the Erasmus+ programme, to Università Politecnica delle Marche in Ancona, Italy, in a Master’s degree in computer science, bringing to light a personal reflection on the goals and benefits of the mobility for both students and teachers. Finally, the author puts forth some suggestions that would improve the whole mobility process. We sincerely hope to have stimulated you to keep on reading, upholding the belief that these texts can represent valuable sources for both teachers and students in their research work.

El pecán (Carya illinoinensis (Wangenh.) K. Koch) es una especie frutal y forestal nativa de América del Norte. Estados Unidos y Mexico representan más del 90 por ciento de la superficie y producción mundial. Argentina ocupa el tercer lugar en el mundo en superficie con 6000 hectáreas implantadas, la mayoría de la cuales se encuentran aún en una etapa juvenil con bajos rendimientos. En el país no hay estudios sobre la respuesta a la fertilización del árbol de pecán en producción. En la presente tesis se investigó el efecto de la fertilización con distintos niveles de nitrógeno (N), fósforo (P) y cinc (Zn) sobre el crecimiento vegetativo, rendimiento y composición química de la hoja y del fruto de árboles de pecan cultivar 'Stuart'. También se evaluó el efecto de la fertilización sobre la concentración de extracto etéreo, tocoferol y proteína en embrión. La fertilización tuvo efecto en el corto plazo sobre las variables tasa de crecimiento en altura y diámetro del árbol mientras que en el rendimiento el efecto fue más tardío. Los tratamientos en kg ha-1 fueron: testigo (T); tratamiento 1 (T1) con 13,2 kg de N , 5,2 kg de P y 5,4 kg de Zn; tratamiento 2 (T2) con 29,7 kg de N , 10,5 kg de P y 10,8 kg de Zn y tratamiento 3 (T3) con 46,2 kg de N , 15,7 kg de P y 21,6 kg de Zn. Se obtuvo la siguiente respuesta en peso de materia seca (MS) de embrión árbol-1: 227 g Testigo (T), 340 g Tratamiento 1 (T1), 301 g Tratamiento 2 (T2) y 558 g Tratamiento 3 (T3). El extracto etéreo no fue influído por la fertilización teniendo una concentración entre 71,51 por ciento y 75,12 por ciento mientras que en su composición en ácidos grasos predominaron los ácidos oleico (C 18:1) con 62,49 por ciento y linoleico (C 18:2) con 26,63 por ciento. Los isómeros ƒÁ-tocoferol, ƒ¿-tocoferol y ƒÀ +ƒÂ-tocoferol tampoco presentaron respuesta a la fertilización, predominado el ƒÁ-tocoferol con una concentración en peso de materia húmeda (MH) de embrión entre 45,96 mg y 55,32 mg ƒÁ-tocoferol 100 g MH-1. La fertilización tuvo influencia sobre el contenido de proteína en el embrión presentando los siguientes valores en porcentaje de MS de embrión: 7,65 por ciento T, 7,81 por ciento T1, 8,36 por ciento T2 y 9 por ciento T3. La fertilización influyó positivamente sobre la concentración de N foliar, negativamente sobre la concentración de P foliar y no tuvo efecto sobre la concentración de Zn foliar. Se encontró una relación lineal positiva entre el N foliar de verano y el peso seco de embrión y una relación lineal negativa entre el N foliar de verano y el contenido de proteína en embrión. La fertilización con N, P y Zn tuvo una influencia positiva sobre el crecimiento y rendimiento del árbol de pecan y la concentración de proteína en embrión. Sin embargo, la fertilización no tuvo efecto sobre la concentración de extracto etereo e isómeros de tocoferol en embrión
