Different molecular-genetic methods were used to identify a cohort of Leishmania strains from natural foci of zoonotic cutaneous leishmaniasis located in Central Asia, on the former USSR territory. The results obtained using isoenzymes, PCR, restriction fragment length polymorphisms of kDNA and molecular hybridization techniques are discussed in terms of their applicability, discrimination power and feasibility for answering questions related to molecular epidemiological research and for detecting mixed Leishmania infections

Investigación producida a partir de una estancia en la Università degli studi di Sassari entre julio y diciembre de 2007. Se han investigado las fortificaciones fenicio-púnicas de la isla de Cerdeña. También se ha realizado labor de investigación a nivel bibliográfico en diferentes bibliotecas de Cerdeña. Los resultados obtenidos han mostrado una imagen totalmente diferente sobre las fortificaciones fenicio-púnicas de Cerdeña. La gran mayorÃa de los vestigios estudiados han resultado ser de época romana o pertenecer a estructuras arquitectónicas que no tiene una función defensiva. Estos resultados hacen que cambie totalmente la visión sobre la presencia militar cartaginesas en la isla, en especial sobre la conquista y el control de la misma.

An alternative model for the geodynamic evolution of Southeast Asia is proposed and inserted in a modern plate tectonic model. The reconstruction methodology is based on dynamic plate boundaries, constrained by data such as spreading rates and subduction velocities; in this way it differs from classical continental drift models proposed so far. The different interpretations about the location of the Palaeotethys suture in Thailand are revised, the Tertiary Mae Yuam fault is seen as the emplacement of the suture. East of the suture we identify an Indochina derived terrane for which we keep the name Shan-Thai, formerly used to identify the Cimmerian block present in Southeast Asia, now called Sibumasu. This nomenclatural choice was made on the basis of the geographic location of the terrane (Eastern Shan States in Burma and Central Thailand) and in order not to introduce new confusing terminology. The closure of the Eastern Palaeotethys is related to a southward subduction of the ocean, that triggered the Eastern Neotethys to open as a back-arc, due to the presence of Late Carboniferous-Early Permian arc magmatism in Mergui (Burma) and in the Lhasa block (South Tibet), and to the absence of arc magmatism of the same age East of the suture. In order to explain the presence of Carboniferous-Early Permian and Permo-Triassic volcanic arcs in Cambodia, Upper Triassic magmatism in Eastern Vietnam and Lower Permian-Middle Permian arc volcanites in Western Sumatra, we introduce the Orang Laut terranes concept. These terranes were detached from Indochina and South China during back-arc opening of the Poko-Song Ma system, due to the westward subduction of the Palaeopacific. This also explains the location of the Cathaysian West Sumatra block to the West of the Cimmerian Sibumasu block.

Eustatic sea level changes during Pleistocene climatic fluctuations produced several cycles of connection-isolation among continental islands of the Sunda shelf. To explore the potential effects of these fluctuations, we reconstructed a model of the vicariant events that separated these islands, based on bathymetric information. Among many possible scenarios, two opposite phylogenetic patterns of evolution were predicted for terrestrial organisms living in this region: one is based on the classical allopatric speciation mode of evolution, while the other is the outcome of a sequential dispersal colonization of the archipelago. We tested the applicability of these predictions with an analysis of sequence variation of the cytochrome b gene from several taxa of Hylomys. They were sampled throughout SE-Asia and the Sunda islands. High levels of haplotype differentiation characterize the different island taxa. Such levels of differentiation support the existence of several allopatric species, as was suggested by previous allozyme and morphological data. Also in accordance with previous results, the occurrence of two sympatric species from Sumatra is suggested by their strongly divergent haplotypes. One species, Hylomys suillus maxi, is found both on Sumatra and in Peninsular Malaysia, while the other, H. parvus, is endemic to Sumatra. Its closest relative is H. suillus dorsalis from Borneo. Phylogenetic reconstructions also demonstrate the existence of a Sundaic clade composed of all island taxa, as opposed to those from the continent. Although there is no statistical support for either proposed biogeographic model of evolution, we argue that the sequential dispersal scenario is more appropriate to describe the genetic variation found among the Hylomys taxa. However, despite strong differentiation among island haplotypes, the cladistic relationships between some island taxa could not be resolved. We argue that this is evidence of a rapid radiation, suggesting that the separation of the islands may have been perceived as a simultaneous event rather than as a succession of vicariant events. Furthermore, the estimates of divergence times between the haplotypes of these taxa suggest that this radiation may actually have predated the climatic fluctuations of the Pleistocene. Further refinement of the initial palaeogeographic models of evolution are therefore needed to account for these results.

Esta memoria parte del estudio de la teorÃa de las Relaciones Internacionales, seguido de un análisis del regionalismo en el Este asiático, asà como del multilateralismo y del minilateralismo como modus operandi en las relaciones internacionales y su desarrollo especÃfico en el Noreste asiático, o Asia oriental. Todo ello se ha examinado con el fin de poder aprehender la dinámica internacional de la segunda crisis nuclear con Corea del Norte, asà como proveer con un mayor entendimiento sobre las conversaciones a seis bandas (6PT), como ejemplo de foro de negociación minilateral creado ad hoc con el fin de buscar una solución al problema norcoreano. Hemos procedido al examen del pensamiento estratégico de los diferentes paÃses que conforman las 6PT, asà como al estudio de los intereses, acuerdos y desacuerdos de cada uno de ellos en la mesa de negociaciones con el objetivo de intentar comprender el porqué de su aparente fracaso a la hora de solucionar dicha crisis nuclear. Finalmente, hemos procedido a un estudio de la comunidad del Noreste asiático y del marco de seguridad existente en la región, asà como de las perspectivas para la institucionalización de las conversaciones a seis bandas para poder comprender si, desarrollado como organización multilateral, este foro podrÃa favorecer la estabilidad en la región, la cooperación regional y con ello una mayor integración.

Aquest Treball Final de Carrera pretén analitzar de manera organitzada els Fons de Riquesa Sobirana, un dels actors amb major rellevà ncia dins de l’economia mundial en els últims anys; sobre el qual es té poca informació, degut principalment, a la seva manca de transparència. Aquest estudi parteix d’un primer anà lisis a nivell macroeconòmic sobre les raons de creació d’aquests fons, i sobre com comencen a agafar importà ncia dins del panorama econòmic actual. A partir d’aquÃ, es desenvolupa l’estudi sobre els països emergents d’Àsia, que utilitzen aquests Fons de Riquesa Sobirana com a vehicles per a canalitzar les seves Inversions cap a l’exterior, amb l’objectiu de diversificar els seus ingressos econòmics, i garantitzar el desenvolupament futur, tant del paÃs com de la població. Finalment, el treball aborda el cas dels Emirats Àrabs Units, un paÃs amb un gran número de Fons de Riquesa Sobirana, que estan prenen posicions en alguns sectors estratègics de moltes economies desenvolupades.

Durant el segle XIX i les primeres dècades del XX, Àsia Central va patir de primera mà la rivalitat entre les dues grans potències europees del moment: Anglaterra i Rússia. Aquest enfrontament va ser batejat pels seus propis participants amb el nom d'El Gran Joc. A diferència d'altres lluites històriques prèvies, el Gran Joc no es va resumir en una guerra, sinó en un cúmul d'elles, que es van succeir al llarg del temps en diferents territoris del centre del continent asià tic i a les que van acompanyar accions diplomà tiques igualment nombroses. Tot i l'extensió del conflicte, Afganistan es va erigir com el punt clau més rellevant al voltant del qual l'Imperi rus i el brità nic van desenvolupar les seves intrigues. Els dos poders europeus, amb els seus respectius objectius en ment, no van dubtar a dur a terme un dels majors desplegaments estratègics mai vist a la zona, valent-se, a més dels seus efectius, dels habitants asià tics com peons al tauler del seu joc i marcant profundament el futur de les nacions centreasià tiques, aixà com establint un precedent en la manera de fer la guerra on la victòria d'una facció sobre una altra mai estaria clara.

This paper proposes a detailed measurement of the agricultural development of the island of Majorca from the late sixteenth century to the midnineteenth century, with an emphasis on the products which made up the bulk of the island’s agricultural production. The authors have organized most of the existing databases in the island’s archives and have also incorporated quantitative and qualitative material from their own research and that of other colleagues. Due to their quality and regularity, the data are among the richest known for pre-industrial Europe. These sources lead to some conclusions which link with recent debates in European economic history concerning the calculation of economic growth in economies for periods before statistics were kept. The text presents a methodological analysis covering almost 80 per cent of agricultural production of the island of Majorca and leaves conclusions to be supplemented by further studies of the manufacturing and service sectors

This paper is an overview of important findings regarding the ongoing evolution of Asian dairy markets based on a series of new economic investigations. These investigations provide systematic empirical foundations for assessing Asian dairy markets with their new consumption patterns, changing industries, and trade prospects under different domestic and trade policy regimes. The findings are drawn from four case studies (China, India, Japan, and Korea), as well as a prospective analysis of future regional patterns of consumption and a policy analysis of trade liberalization of Asian dairy markets. The overview distills the findings of these new investigations and integrates them in the earlier economic literature; it draws policy implications and identifies lessons for countries outside of Asia, especially for emerging exporters in Latin America.

The detailed geological mapping and structural study of a complete transect across the northwestern Himalaya allow to describe the tectonic evolution of the north Indian continental margin during the Tethys ocean opening and the Himalayan Orogeny. The Late Paleozoic Tethys rifting is associated with several tectonomagmatic events. In Upper Lahul and SE Zanskar, this extensional phase is recorded by Lower Carboniferous synsedimentary transtensional faults, a Lower Permian stratigraphic unconformity, a Lower Permian granitic intrusion and middle Permian basaltic extrusions (Panjal Traps). In eastern Ladakh, a Permian listric normal fault is also related to this phase. The scarcity of synsedimentary faults and the gradual increase of the Permian syn-rift sediment thickness towards the NE suggest a flexural type margin. The collision of India and Asia is characterized by a succession of contrasting orogenic phases. South of the Suture Zone, the initiation of the SW vergent Nyimaling-Tsarap Nappe corresponds to an early phase of continental underthrusting. To the S, in Lahul, an opposite underthrusting within the Indian plate is recorded by the NE vergent Tandi Syncline. This structure is associated with the newly defined Shikar Beh Nappe, now partly eroded, which is responsible for the high grade (amphibolite facies) regional metamorphism of South Lahul. The main thrusting of the Nyimaling-Tsarap Nappe followed the formation of the Shikar Beh Nappe. The Nyimaling-Tsarap Nappe developed by ductile shear of the upper part of the subducted Indian continental margin and is responsible for the progressive regional metamorphism of SE Zanskar, reaching amphibolite facies below the frontal part of the nappe, near Sarchu. In Upper Lahul, the frontal parts of the Nyimaling-Tsarap and Shikar Beh nappes are separated by a zone of low grade metamorphic rocks (pumpellyite-actinolite facies to lower greenschist facies). At high structural level, the Nyimaling-Tsarap Nappe is characterized by imbricate structures, which grade into a large ductile shear zone with depth. The related crustal shortening is about 87 km. The root zone and the frontal part of this nappe have been subsequently affected by two zones of dextral transpression and underthrusting: the Nyimaling Shear Zone and the Sarchu Shear Zone. These shear zones are interpreted as consequences of the counterclockwise rotation of the continental underthrusting direction of India relative to Asia, which occurred some 45 and 36 Ma ago, according to plate tectonic models. Later, a phase of NE vergent `'backfolding'' developed on these two zones of dextral transpression, creating isoclinal folds in SE Zanskar and more open folds in the Nyimaling Dome and in the Indus Molasse sediments. During a late stage of the Himalayan Orogeny, the frontal part of the Nyimaling-Tsarap Nappe underwent an extension of about 15 km. This phase is represented by two types of structures, responsible for the tectonic unroofing of the amphibolite facies rocks of the Sarchu area: the Sarchu high angle Normal Fault, cutting a first set of low angle normal faults, which have been created by reactivation of older thrust planes related to the Nyimaling-Tsarap Nappe.
