Development of the hub port of Colombo, Sri Lanka
No full textThe Port of Colombo, Sri Lanka, is an important hub port in the Indian Ocean. A hub port is a port with mainly transhipment (and in this case container) throughput, which means that most of the cargo is not for the country itself, but for countries in the region. The yearly container throughput at the Port of Colombo reached its full capacity of 1.7 million TEU per year in 1997. Increasing waiting times for ships calling at the port are a result of this. Because of the costs of a waiting ship, shipping lines will choose other ports in the region such as Singapore, Salalah (Oman) or Dubai (United Arab Emirates) for their ships to go to. The aim of this study is to develop a plan for a New Container Terminal, which will give the Port of Colombo enough container throughput capacity for the next 25 years: till the year 2025.Hydraulic EngineeringCivil Engineering and Geoscience
Sindicatos y cultura obrera en tiempos de Vandor: Buenos Aires, 1958 – 1969
No full textEn este trabajo se abordan las características de la cultura obrera de los trabajadores de Buenos Aires, con énfasis en los trabajadores metalúrgicos, desde la caída de Perón en 1955 hasta 1969. El estudio destaca la poca atención brindada por la historiografía obrera en el análisis de la cultura obrera en relación a las transformaciones de la política, las instituciones sindicales y los conflictos laborales de la época. Se estudian algunas de las bases sobre las que se asienta esa cultura: las tradiciones obreras en el contexto del fortalecimiento político y social de los sindicatos peronistas encabezado por el líder metalúrgico Augusto Timoteo Vandor. También da cuenta del uso del tiempo libre de los trabajadores, su relación con algunas de las industrias culturales y los deportes masivos en una década de modernización. En este trabajo también se aborda la relación entre la cultura obrera y la cultura de clase media. Asimismo, se hace referencia a como todos estos factores moldean y reafirmaron entre los trabajadores una identidad política definida en los años sesenta y prefiguran algunos de los conflictos de principios de los años setenta.Fil: Colombo, Edgardo Hugo.

Orbit design for future SpaceChip swarm missions in a planetary atmosphere
No full textThe effect of solar radiation pressure and atmospheric drag on the orbital dynamics of satellites-on-a-chip (SpaceChips) is exploited to design equatorial long-lived orbits about the oblate Earth. The orbit energy gain due to asymmetric solar radiation pressure, considering the Earth's shadow, is used to balance the energy loss due to atmospheric drag. Future missions for a swarm of SpaceChips are proposed, where a number of small devices are released from a conventional spacecraft to perform spatially distributed measurements of the conditions in the ionosphere and exosphere. It is shown that the orbit lifetime can be extended and indeed selected through solar radiation pressure and the end-of-life re-entry of the swarm can be ensured, by exploiting atmospheric drag
Alongatepyris pedrocai Colombo & Perkovsky & Azevedo 2022, sp. nov.
No full text† Alongatepyris pedrocai Colombo & Azevedo, sp. nov. (Figs 2, 3) Type material. Holotype female, piece code WDC F-3, deposited in the IBES collection: a complete flat wasp is embedded in a median amber piece; some scattered debris obscuring particular details; no other animals and plants are present. The amber was not subjected to any fixation. Etymology. The specific epithet pedrocai is named after Pedroca, Pedro Dhaví Colombo Zanette’s nickname, nephew of the first author. Diagnosis. Head as long as wide in dorsal view. Anterior ocellus posterior to supra-ocular line. Posterior pronotal sulcus absent. Forewing with 2r-rs&Rs vein long and tubular.The species platunissimus and A. ingens are redraw digitally from Vargas & Azevedo (2008). Description. Female. Body length ~ 3.8 mm. Color: body mostly black, palpi and mandible dark castaneous; tarsi light castaneous;wings hyaline,veins light castaneous. Head as long as wide in dorsal view, not globoid in lateral view. Mandible apparently with three teeth, ventral tooth large. Clypeus with median lobe rounded and lateral lobes reduced. Eye located far from mandibular base, glabrous, elongated in lateral view, bulging in dorsal view. Antenna with flagellomeres wider than long, first flagellomeres shorter than distal ones; flagellar pubescence suberect; pedicel with apex dilated, longer than flagellomere I. Frontal line indistinct. Ocelli conspicuous. Anterior ocellus posterior to supra-ocular line. Dorsal pronotal area longer than mesoscutellum. Posterior pronotal sulcus absent. Notaulus not visible. Parapsidal signum present. Mesoscuto-scutellar suture with sulcus not visible. Mesopleuron with lower mesopleural fovea not visible. Macropterous. Forewing with three cells closed (C, R and 1Cu); C cell very narrow; 1Cu cell more than 2× shorter than R cell; Pterostigma small and prostigma large; flexion line simple distally; 2r-rs&Rs vein long and tubular. Mesotibia not spinose. Metapectal-propodeal disc long, touching posterior margin of anteromesoscutum; transverse anterior carina straight; metapostnotal median carina not visible; transverse posterior carina not visible. Tarsal claw simple. Metasoma polished. Remarks. The specimen described above is assigned to the genus Alongatepyris based on the following character states: (1) the body is flattened in the lateral view; (2) the eyes are placed forward on the head; (3) the antennae are composed by 11 flagellomeres; (4) the forewings are fully developed; and (5) the first cubital cell of the forewings is much reduced. The specimen considered here is morphologically similar to A. platunissimus, because the head is as long as wide and the 2r-rs&Rs veins of the forewings are long and tubular. The specimen is also morphologically similar to A. ingens because the dorsal pronotal area is ecarinate and the 1Cu cell of the forewings is more than 2× shorter than the R cell. The presence of morphological features of the two species previously described, A. platunissimus and A. ingens, supports that this lineage is different from its congeners. Additionally, † A. pedrocai, sp. nov. lived between 15–20 million years ago, adding further support to the validity of this species. Type locality and horizon. Dominican amber, Burdigalian / Langhian terrestrial amber in the Dominican Republic. Miocene, 15–20 million years ago.Published as part of Colombo, Wesley D., Perkovsky, Evgeny E. & Azevedo, Celso O., 2022, Synopsis of the rare genus Alongatepyris (Hymenoptera, Bethylidae), with description of the first extinct species from Dominican amber, pp. 57-65 in Palaeoentomology 5 (1) on pages 58-59, DOI: 10.11646/palaeoentomology.5.1.6, http://zenodo.org/record/628063

No full textIncludes abstract.Includes bibliographical references and index.This thesis profiles the conductors of the Cape Municipal Orchestra since its inception in 1914 until the resignation of David Tidboald in 1965. After the introductory Chapter 1, Chapter 2 includes a historic review of the period before 1914. It also highlights the influences leading towards the inauguration of the Cape Municipal Orchestra. Chapters 3-7 discuss the permanent conductors who conducted between 1914 and 1954. The following list extends from the dates of their first concerts up to their resignations, or up to the date of their final concerts: Theo Wendt (from 28 February 1914 to 30 September 1924: a period of about 10 years). Leslie Heward (from 17 July 1924 to 31 May 1926: a period of about 2 years). William Pickerill (from 5 May 1927 to 12 October 1946: a period of about 19 years). Geoffrey Miller as Associate Conductor (from 31 October 1946 to 19 February1948: a period of nearly two years). Enrique Jordá (from 19 February 1948 to 31 December 1953: a period of nearly five years). Assistant and guest conductors are discussed within these chapters. Chapter 8 discusses guest conductors from January 1954 until June 1960. Here they are organised chronologically accordingto their first appearances. Chapter 9 deals with the period of David Tidboald's conductorship (from 20 August 1960 to1 July 1965). The concluding remarks of Chapter 10 briefly touch on such aspects as the number of premieres, recurrence of works mentioned in this thesis, and the guest conducting system
Repercusiones Económicas surgidas por el Fenómeno del Contrabando en la Región Colombo – Venezolana.
No full text114 p.Colombia is a country that shares a border with Venezuela and four other countries. This allows them to present a very dynamic trade, where the primary objective was the economic benefit of the countries participating in the exchange. The case of the Colombian-Venezuelan border is unique. The difference in the purchasing power of the Venezuelan currency, the crisis by the lack of foreign exchange has generated an economic, political and social crisis where many residents have seen easy way out of this crisis, smuggling.
Smuggling is an offense under the Criminal Code, and is one of the main problems in the border region. Today this scourge is affecting the economy of both countries as they are being used as objects of that crime, food, medicines and products of the basic basket and constitute the staple items. Around this author he determined the purpose of analyzing the economic impacts arising from the phenomenon of smuggling in the region Colombo Venezolana Theorists contributions formed the basis of the investigation and that through consultation could deepen about the border issue. Also, I was investigated on the condition of the Venezuelan colombo region as smuggling, which has been the impact on the economy of both countries and finally the effects of smuggling in the formal and informal economy. This was a descriptive documentary research. As an idea to defend it suggests that border development should be taken as a national target, regardless of the situation of border that is in effect at a given time, purpose in which bilateral initiatives with neighboring countries can be an important part of the strategy to implement.Colombia es un pais que comparte frontera con Venezuela y cuatro paises mas. Esto permite que se presente un intercambio comercial muy dinamico, donde el objetivo primordial ha sido el beneficio economico de los paises participantes en dicho intercambio. El caso de la frontera colombo-venezolana es unico. La diferencia del poder dquisitivo de la moneda venezolana, la crisis por la ausencia de divisas ha generado una crisis economica, politica y social donde muchos de sus habitantes han visto como salida facil de esa crisis, el contrabando. El contrabando es un delito tipificado en el Código Penal, y constituye uno de los principales problemas en la region fronteriza. En la actualidad este flagelo esta afectando la economia de ambos paises, ya que se estan utilizando como objetos de ese delito, los alimentos, las medicinas y los productos de la cesta basica y que se constituyen en los articulos de primera necesidad. En torno a esto la autora determinó como propósito analizar las repercusiones economicas surgidas por el fenomeno del contrabando en la region Colombo Venezolana Los aportes teoricos, constituyeron la base de la investigación ya que a traves de su consulta se pudo profundizar sobre el tema del problema fronterizo. Igualmente, se investigo sobre la condicion de la region colombo venezolana en cuanto al contrabando, cual ha sido la incidencia en la economia de ambos paises y finalmente los efectos del contrabando en la economia formal e informal.
Se trató de una investigación documental de carácter descriptivo. Como idea a defender se plantea que el desarrollo fronterizo debe ser asumido como un objetivo nacional, independientemente de la situación de frontera que tenga vigencia en un momento dado, propósito en el cual las iniciativas bilaterales con los países limítrofes, pueden constituir parte importante de la estrategia a poner en práctica.CONTENIDO
