Effect of sex and seasons of the year on hematologic and serum biochemical variables of captive brown brocket deer (Mazama gouazoubira)

The Brown brocket deer (Mazama gouazoubira) is the most common free-living and captive deer in South America, especially in Brazil, and has great ecological and scientific significance. However, data on hematological and biochemical parameters in brown brocket deer are scarce. The goal of this study was to establish reference ranges for hematological and biochemical parameters of Mazama gouazoubira, comparing differences during the seasons of the year and between sex. Blood samples from ten adult healthy brown brocket deer (6 female and 4 male) were collected during daytime, monthly, during 12 months. The animals were maintained in individual stable, protected from noise and fed ad libitum with commercial ration and green fodder. For blood collection, animals were submitted to physical restrain for no longer than 2 minutes. The following parameters were determined: red blood cell count (RBC), haemoglobin concentration, packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), white blood cell count (WBC), platelet count, enzyme activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) and serum levels of alkaline phosphatase (ALP), creatine kinase (CK), total protein (TP), albumin, cholesterol, total calcium, ionic calcium, sodium, potassium, magnesium, triglycerides, creatinine and urea. Values were compared according to season and sex. RBC count, WBC count and MCV suggested seasonal influence. Haemoglobin concentration, PCV and MCV were influenced by sex. Serum concentration of total calcium, ionic calcium, sodium, potassium and magnesium were influenced by season. Serum magnesium was also influenced by sex. The blood parameters herein reported may be useful as reference values for diagnostic and prognostic purposes in captive brown-brocket deer.

Microphallus fonti sp. n. (Digenea: Microphallidae) from the Red Swamp Crawfish in Southern United States

A new species of digenean, Microphallus fonti, is described from the red swamp crawfish in Louisiana, USA. It has a small pharynx and a rudimentary gut like M. opacus and possibly related species from crayfishes, but it differs from them by its relatively large male copulatory papilla and a conspicuous metraterm.

THE EFFECTS OF ORNITROL ON WILD POPULATIONS OF RED-WINGED BLACKBIRDS AND GRACKLES

For the past three years the New Jersey Department of Agriculture, in coop¬eration with the New Jersey Agricultural Experiment Station, has conducted field evaluations on the effects of reproductive suppressants on wild populations of red-winged blackbirds. These studies have been performed in conjunction with the North East 49 (a Federally sponsored regional project which presently has nine states in the North East and Ohio cooperating to develop means to combat bird damage to agricultural crops) regional project on control of bird depredations. Field evaluations in 1968 and 1969 centered around the effects of TEM (tri-ethylene melamine) on the reproductive rates of red-winged blackbirds. At the close of the 1969 season further field testing of the chemical was discontinued because of the material's apparent lack of effectiveness as a reproductive inhibitor. In 1970 the field evaluations were conducted to determine the effects of Orni-trol (20, 25-diazocholesterol dihydrochloride, supplied by G. D. Searle and Company, Chicago, Illinois) on the reproductive rates of red-winged blackbirds. A small colony of common grackles was also studied during this same investigation.

Morphological and molecular studies on the Brazilian native red seaweed Laurencia oliveirana (Rhodomelaceae, Ceramiales)

Morphological and molecular studies were carried out on Laurencia oliveirana from the type locality (Arraial do Cabo, Rio de Janeiro, Brazil). This species is easily recognized by its small size, sub-erect habit forming intricate cushion-like tufts and unilateral pectinate branching. The species displays all the typical characters of the genus Laurencia, such as the production of the first pericentral cell underneath the basal cell of the trichoblast, tetrasporangia produced from particular pericentral cells, with the third and fourth pericentral cells becoming fertile, without production of additional pericentral cells, spermatangial branches produced from one of two laterals on the suprabasal cell of trichoblasts, and procarp-bearing segment with five pericentral cells. Details of tetrasporangial plants and development of procarp and male plants are described for the first time for the species. The phylogenetic position of L. oliveirana was inferred by analysis of the chloroplast-encoded rbcL gene sequences from 57 taxa. In all phylogenetic analyses, L. oliveirana grouped with L. caraibica, L. caduciramulosa, L. venusta and L. natalensis, forming a monophyletic clade within the Laurencia sensu stricto. The genetic divergence between L. oliveirana and the molecularly closest species, L. caraiba collected in Brazil, was 2.3%.

Ecological modelling of the phytoplankton dynamics in the northern Gulf of Aqaba (Red Sea)

The Gulf of Aqaba represents a small scale, easy to access, regional analogue of larger oceanic oligotrophic systems. In this Gulf, the seasonal cycles of stratification and mixing drives the seasonal phytoplankton dynamics. In summer and fall, when nutrient concentrations are very low, Prochlorococcus and Synechococcus are more abundant in the surface water. This two populations are exposed to phosphate limitation. During winter mixing, when nutrient concentrations are high, Chlorophyceae and Cryptophyceae are dominant but scarce or absent during summer. In this study it was tried to develop a simulation model based on historical data to predict the phytoplankton dynamics in the northern Gulf of Aqaba. The purpose is to understand what forces operate, and how, to determine the phytoplankton dynamics in this Gulf. To make the models data sampled in two different sampling station (Fish Farm Station and Station A) were used. The data of chemical, biological and physical factors, are available from 14th January 2007 to 28th December 2009. The Fish Farm Station point was near a Fish Farm that was operational until 17th June 2008, complete closure date of the Fish Farm, about halfway through the total sampling time. The Station A sampling point is about 13 Km away from the Fish Farm Station. To build the model, the MATLAB software was used (version 7.6.0.324 R2008a), in particular a tool named Simulink. The Fish Farm Station models shows that the Fish Farm activity has altered the nutrient concentrations and as a consequence the normal phytoplankton dynamics. Despite the distance between the two sampling stations, there might be an influence from the Fish Farm activities also in the Station A ecosystem. The models about this sampling station shows that the Fish Farm impact appears to be much lower than the impact in the Fish Farm Station, because the phytoplankton dynamics appears to be driven mainly by the seasonal mixing cycle.

Size-selective investigations of spectral and emission properties of small particles and nanotubes

In dieser Arbeit wurde die Elektronenemission von Nanopartikeln auf Oberflächen mittels spektroskopischen Photoelektronenmikroskopie untersucht. Speziell wurden metallische Nanocluster untersucht, als selbstorganisierte Ensembles auf Silizium oder Glassubstraten, sowie ferner ein Metall-Chalcogenid (MoS2) Nanoröhren-Prototyp auf Silizium. Der Hauptteil der Untersuchungen war auf die Wechselwirkung von fs-Laserstrahlung mit den Nanopartikeln konzentriert. Die Energie der Lichtquanten war kleiner als die Austrittsarbeit der untersuchten Proben, so dass Ein-Photonen-Photoemission ausgeschlossen werden konnte. Unsere Untersuchungen zeigten, dass ausgehend von einem kontinuierlichen Metallfilm bis hin zu Clusterfilmen ein anderer Emissionsmechanismus konkurrierend zur Multiphotonen-Photoemission auftritt und für kleine Cluster zu dominieren beginnt. Die Natur dieses neuen Mechanismus` wurde durch verschiedenartige Experimente untersucht. Der Übergang von einem kontinuierlichen zu einem Nanopartikelfilm ist begleitet von einer Zunahme des Emissionsstroms von mehr als eine Größenordnung. Die Photoemissions-Intensität wächst mit abnehmender zeitlicher Breite des Laserpulses, aber diese Abhängigkeit wird weniger steil mit sinkender Partikelgröße. Die experimentellen Resultate wurden durch verschiedene Elektronenemissions-Mechanismen erklärt, z.B. Multiphotonen-Photoemission (nPPE), thermionische Emission und thermisch unterstützte nPPE sowie optische Feldemission. Der erste Mechanismus überwiegt für kontinuierliche Filme und Partikel mit Größen oberhalb von mehreren zehn Nanometern, der zweite und dritte für Filme von Nanopartikeln von einer Größe von wenigen Nanometern. Die mikrospektroskopischen Messungen bestätigten den 2PPE-Emissionsmechanismus von dünnen Silberfilmen bei „blauer“ Laseranregung (hν=375-425nm). Das Einsetzen des Ferminiveaus ist relativ scharf und verschiebt sich um 2hν, wenn die Quantenenergie erhöht wird, wogegen es bei „roter“ Laseranregung (hν=750-850nm) deutlich verbreitert ist. Es zeigte sich, dass mit zunehmender Laserleistung die Ausbeute von niederenergetischen Elektronen schwächer zunimmt als die Ausbeute von höherenergetischen Elektronen nahe der Fermikante in einem Spektrum. Das ist ein klarer Hinweis auf eine Koexistenz verschiedener Emissionsmechanismen in einem Spektrum. Um die Größenabhängigkeit des Emissionsverhaltens theoretisch zu verstehen, wurde ein statistischer Zugang zur Lichtabsorption kleiner Metallpartikel abgeleitet und diskutiert. Die Elektronenemissionseigenschaften bei Laseranregung wurden in zusätzlichen Untersuchungen mit einer anderen Anregungsart verglichen, der Passage eines Tunnelstroms durch einen Metall-Clusterfilm nahe der Perkolationsschwelle. Die elektrischen und Emissionseigenschaften von stromtragenden Silberclusterfilmen, welche in einer schmalen Lücke (5-25 µm Breite) zwischen Silberkontakten auf einem Isolator hergestellt wurden, wurden zum ersten Mal mit einem Emissions-Elektronenmikroskop (EEM) untersucht. Die Elektronenemission beginnt im nicht-Ohmschen Bereich der Leitungsstrom-Spannungskurve des Clusterfilms. Wir untersuchten das Verhalten eines einzigen Emissionszentrums im EEM. Es zeigte sich, dass die Emissionszentren in einem stromleitenden Silberclusterfilm Punktquellen für Elektronen sind, welche hohe Emissions-Stromdichten (mehr als 100 A/cm2) tragen können. Die Breite der Energieverteilung der Elektronen von einem einzelnen Emissionszentrum wurde auf etwa 0.5-0.6 eV abgeschätzt. Als Emissionsmechanismus wird die thermionische Emission von dem „steady-state“ heißen Elektronengas in stromdurchflossenen metallischen Partikeln vorgeschlagen. Größenselektierte, einzelne auf Si-Substraten deponierte MoS2-Nanoröhren wurden mit einer Flugzeit-basierten Zweiphotonen-Photoemissions-Spektromikroskopie untersucht. Die Nanoröhren-Spektren wiesen bei fs-Laser Anregung eine erstaunlich hohe Emissionsintensität auf, deutlich höher als die SiOx Substratoberfläche. Dagegen waren die Röhren unsichtbar bei VUV-Anregung bei hν=21.2 eV. Eine ab-initio-Rechnung für einen MoS2-Slab erklärt die hohe Intensität durch eine hohe Dichte freier intermediärer Zustände beim Zweiphotonen-Übergang bei hν=3.1 eV.

Applications of remote sensing and geographic information systems in geomorphological studies: Safaga - El Quseir area, Red Sea coast, Egypt as an example

In den letzten drei Jahrzehnten sind Fernerkundung und GIS in den Geowissenschaften zunehmend wichtiger geworden, um die konventionellen Methoden von Datensammlung und zur Herstellung von Landkarten zu verbessern. Die vorliegende Arbeit befasst sich mit der Anwendung von Fernerkundung und geographischen Informationssystemen (GIS) für geomorphologische Untersuchungen. Durch die Kombination beider Techniken ist es vor allem möglich geworden, geomorphologische Formen im Überblick und dennoch detailliert zu erfassen. Als Grundlagen werden in dieser Arbeit topographische und geologische Karten, Satellitenbilder und Klimadaten benutzt. Die Arbeit besteht aus 6 Kapiteln. Das erste Kapitel gibt einen allgemeinen Überblick über den Untersuchungsraum. Dieser umfasst folgende morphologische Einheiten, klimatischen Verhältnisse, insbesondere die Ariditätsindizes der Küsten- und Gebirgslandschaft sowie das Siedlungsmuster beschrieben. Kapitel 2 befasst sich mit der regionalen Geologie und Stratigraphie des Untersuchungsraumes. Es wird versucht, die Hauptformationen mit Hilfe von ETM-Satellitenbildern zu identifizieren. Angewandt werden hierzu folgende Methoden: Colour Band Composite, Image Rationing und die sog. überwachte Klassifikation. Kapitel 3 enthält eine Beschreibung der strukturell bedingten Oberflächenformen, um die Wechselwirkung zwischen Tektonik und geomorphologischen Prozessen aufzuklären. Es geht es um die vielfältigen Methoden, zum Beispiel das sog. Image Processing, um die im Gebirgskörper vorhandenen Lineamente einwandfrei zu deuten. Spezielle Filtermethoden werden angewandt, um die wichtigsten Lineamente zu kartieren. Kapitel 4 stellt den Versuch dar, mit Hilfe von aufbereiteten SRTM-Satellitenbildern eine automatisierte Erfassung des Gewässernetzes. Es wird ausführlich diskutiert, inwieweit bei diesen Arbeitsschritten die Qualität kleinmaßstäbiger SRTM-Satellitenbilder mit großmaßstäbigen topographischen Karten vergleichbar ist. Weiterhin werden hydrologische Parameter über eine qualitative und quantitative Analyse des Abflussregimes einzelner Wadis erfasst. Der Ursprung von Entwässerungssystemen wird auf der Basis geomorphologischer und geologischer Befunde interpretiert. Kapitel 5 befasst sich mit der Abschätzung der Gefahr episodischer Wadifluten. Die Wahrscheinlichkeit ihres jährlichen Auftretens bzw. des Auftretens starker Fluten im Abstand mehrerer Jahre wird in einer historischen Betrachtung bis 1921 zurückverfolgt. Die Bedeutung von Regentiefs, die sich über dem Roten Meer entwickeln, und die für eine Abflussbildung in Frage kommen, wird mit Hilfe der IDW-Methode (Inverse Distance Weighted) untersucht. Betrachtet werden außerdem weitere, regenbringende Wetterlagen mit Hilfe von Meteosat Infrarotbildern. Genauer betrachtet wird die Periode 1990-1997, in der kräftige, Wadifluten auslösende Regenfälle auftraten. Flutereignisse und Fluthöhe werden anhand von hydrographischen Daten (Pegelmessungen) ermittelt. Auch die Landnutzung und Siedlungsstruktur im Einzugsgebiet eines Wadis wird berücksichtigt. In Kapitel 6 geht es um die unterschiedlichen Küstenformen auf der Westseite des Roten Meeres zum Beispiel die Erosionsformen, Aufbauformen, untergetauchte Formen. Im abschließenden Teil geht es um die Stratigraphie und zeitliche Zuordnung von submarinen Terrassen auf Korallenriffen sowie den Vergleich mit anderen solcher Terrassen an der ägyptischen Rotmeerküste westlich und östlich der Sinai-Halbinsel.

Protein changes and proteolytic degradation in red and white clover plants subjected to waterlogging

Red (Trifolium pratense L., cv. “Start”) and white clover varieties (Trifolium repens L., cv. “Debut” and cv. “Haifa”) were waterlogged for 14 days and subsequently recovered for the period of 21 days. Physiological and biochemical responses of the clover varieties were distinctive, which suggested different sensitivity toward flooding. The comparative study of morphological and biochemical parameters such as stem length, leaflet area, dry weight, protein content, protein pattern and proteolytic degradation revealed prominent changes under waterlogging conditions. Protease activity in the stressed plants increased significantly, especially in red clover cv. “Start”, which exhibited eightfold higher azocaseinolytic activity compared to the control. Changes in the protein profiles were detected by SDS-PAGE electrophoresis. The specific response of some proteins (Rubisco, Rubisco-binding protein, Rubisco activase, ClpA and ClpP protease subunits) toward the applied stress was assessed by immunoblotting. The results characterized the red clover cultivar “Start” as the most sensitive toward waterlogging, expressing reduced levels of Rubisco large and small subunits, high content of ClpP protease subunits and increased activity of protease isoforms.

Near infra-red-activatable nanocarriers for selective cancer diagnosis and treatment

Standard treatment strategies for cancer patients include surgery, radiation therapy, and chemotherapy. Although these strategies have been proven effective, they also have associated limitations. An attractive and innovative approach that can be used alone or in combination with the above modalities is based on the systemic or topical administration of a nanomaterial-based photoactive compound. Interaction with light in the near infrared (NIR) region results in either emission of fluorescence, which can be used for photodetection, or absorption of light which results in phototherapy. Nanomaterials have the advantage of providing multi-functional and unique properties in a single device that cannot be readily acquired with conventional small molecular weight compounds. ^ In this study, three different novel nanocarrier systems were designed and evaluated in mediating photodetection and phototherapy in the NIR. The first compound synthesized was a dual-labeled magnetic resonance/optical imaging agent for sentinel lymph node mapping and biopsy. This dual-labeled agent combines the high resolution of magnetic resonance imaging with the highly sensitive detection of optical imaging. The second imaging agent was an activatable optical imaging agent used to monitor cathepsin B activity in vivo and to probe the degradation of poly(L-glutamic acid). This polymeric nanocarrier offers highly sensitive technique for the detection of enzymatic activity, with is not yet possible with small molecular weight compounds. The third agent was a C225-conjugated hollow nanoshell that is targeted to epidermal growth factor receptors. This targeting agent has been demonstrated to mediate photothermal therapy both in vitro and in vivo. ^ These nanocarrier systems are an invaluable tool for the detection of cancer and many other diseases. With improved targeted delivery of these agents, the ability to diagnose diseases will become more sensitive and more specific. Finally, when designed properly, these agents would allow concurrent diagnosis and treatment of patients of various diseases. ^

In vitro propagation of Glandularia peruviana (L.) Small, an ornamental native plant from South America

The flower market is characterized by being both eager for novelties and highly competitive. The exploration of native species with ornamental potential represents a remarkable area of research, since it entails the introduction and development of novel promising ornamental crops. The genus Glandularia, widely distributed in Argentina, holds an enormous ornamental potential, due to the variety of colors of its inflorescences (red, violet, white, rose and lily), and extended flowering period. There is little information on tissue culture of Glandularia, thus highlighting the relevance of this research. In this work, the conditions for in vitro multiplication of G. peruviana were optimized. It was concluded that WPM supplemented with TDZ, in concentrations ranging from 1.1 to 9.0 μM, was the most adequate treatment, rendering a multiplication rate of approximately 10 de novo shoots per explant. This paper presents a protocol for the in vitro propagation of this species and introduces interesting prospects in the application of biotechnological tools to breed Glandularia.

The hydropolyp fauna of the Red Sea area

46 hydropolyp species of 28 genera and 10 families were sampled during the "Meteor" passage 1964/65 (IIOE) through the Red Sea and its northern and southern exits and on the occasion of several ecological investigations of 29 selected coral reef sections of the central Red Sea and the Gulf of Aqaba. These collections comprise 128 single records of hydropolyp species. Three species and two genera each with one species are doubtful. 25 species, seven genera, one family and one subfamily, together from 49 records have not previously been found in the Red Sea and its exits. Including these newly reported species, the total list increases from 64 species and 112 records to 89 species and 240 single records and 51 additional ones. Scanning microscopical photos, made for the first time for the illustration of the hydropolyps, have been shown to be suitable for a better characterization and diagnosis of the species. Qualified results on the reasons for the horizontal distribution of the species known from the Red Sea area cannot be given because of the low number of samples sporadically distributed through the whole area. In contrast with this fact, the vertical spread of the species sampled seems primarily to be regulated by water exchange and light intensity. For example, four species of hydropolyps are excellent indicators of certain abiotic factors or combinations of them: Gymnangium eximium reacts extremely stenophote-photophobe-rheophil, Eudendrium ramosum moderately stenophote-photophobe-rheophobe, Lytocarpus philippinus moderately stenophote-photophil-rheophil, and Halocordyle disticha var. australis extremely stenophote-photophil but moderately rheophil. Other species have been found throughout all the light zones. Combined with the small size of their colonies their euryphotic behaviour does not allow their use as indicator species.

Relaciones entre los usos del suelo, las infraestructuras y la planificación: incidencia de la red viaria y el planeamiento en la aparición del terciario para el caso de la N-VI

Esta tesis examina el papel de la red viaria y el planeamiento urbanístico en la localización de las actividades terciarias. A partir de los años sesenta se produce una modificación de los patrones de comportamiento espacial de las actividades productivas. En la raíz de estos cambios está los procesos de globalización e internacionalización de la economía y un importante aumento de la utilización vehículos privados. Todo ello da lugar a una preocupación entre los profesionales por la identificación de variables en esa organización espacial, y por la búsqueda de modelos que mejorasen las condiciones de competitividad en el entramado urbano, reclamado también la formulación de conceptos diferentes, capaces de entender los cambios territoriales de la reestructuración permanente en que viven las economías capitalistas avanzadas. En este marco, hay un aumento importante de las actividades terciarias o proceso de terciarización; que es el principio basilar para la suburbanización de este sector. Consiste, en buena medida, en unas necesidades de descentralización y dispersión de las actividades terciarias por todo el territorio, con demandas de nuevos espacios para todo tipo de actividades empresariales. Se va así generando un espacio urbano complejo, con nuevas actividades, distintas de la residencial, y con tipologías edificatorias diferentes: centros comerciales, hipermercados, zocos o edificios de empresas dedicadas a servicios avanzados y altamente cualificados. Adquiere, por tanto, un fuerte protagonismo los espacios periféricos de las grandes ciudades. En la transformación de este territorio interviene el planeamiento urbanístico porque prevé la ocupación del suelo y la forma de uso. Y también la carretera considerada clave en el desarrollo histórico de la ciudad. Consecuentemente, se impulsan una plétora de nuevas líneas de investigación y nuevas formas de aproximación al estudio de las relaciones entre las infraestructuras viarias y los usos del suelo. El interés del proyecto de investigación es, por todo ello, estudiar en que medida la localización del terciario depende del planeamiento urbano y de las variaciones en la red viaria. Es decir, la hipótesis de este trabajo se puede enunciar diciendo que: en la aparición del terciario inciden dos variables, el planeamiento urbanístico y la red viaria; lógicamente siendo consciente de la dificultad intrínseca de separar algún parámetro y sus relaciones de un sistema funcional urbano. Centrando este enfoque sobre el caso particular del corredor de la carretera de La Coruña (N-VI) situado en el oeste de la Comunidad de Madrid. Es un ámbito suburbano que comprende los términos municipales de Las Rozas y Majadahonda, un segmento del municipio de Madrid (abarca los barrios de Aravaca, el Plantío y Valdemarín, y una pequeña superficie de la Casa de Campo, Ciudad Universitaria y El Pardo), y la mitad septentrional del municipio de Pozuelo de Alarcón. La conclusión general a la que se ha llegado es que se trata de un fenómeno complejo, en el que se detecta que: A) La aprobación de un nuevo Plan Urbanístico no supone un cambio inmediato en la evolución cuantitativa de la implantación de actividades terciarias en edificio exclusivo en el área de estudio. B) Se evidencia una relación directa entre la implantación de una nueva infraestructura de transporte o modificación de algún elemento importante y el crecimiento de la localización de actividades terciarias. C) Resulta difícil verificar que cuando confluyen mejoras o nuevas construcciones en la red viaria y una estrategia en el planeamiento dirigida a la ordenación e intervención del espacio terciario, el número de edificios terciarios aumente. ABSTRACT This thesis examines the role of road networks and urban planning in the location of tertiary activities. Since the sixties there is a modification of spatial behavior patterns of production activities. At the root of these changes is the process of globalization and internationalization of the economy and a significant increase in private car use. This leads to a concern among professionals in the identification of variables in the spatial organization, and the search for models that would improve the competitive conditions in the urban framework, also called for the formulation of different concepts, able to understand the changes territorial restructuring that live permanently in the advanced capitalist economies. In this context, there is a significant increase in tertiary activities or process outsourcing, which is the beginning basilar to the suburbanization of the sector. It consists, in large part, on the Needs of decentralization and dispersal of tertiary activities throughout the territory, demands for new spaces for all types of business activities. It is thus generating a complex urban area, with new activities, other than residential and with different building typologies: shopping malls, hypermarkets, souks and buildings of companies engaged in advanced and highly skilled services. Thus takes strong role peripheral areas of big cities. In the transformation of this region is involved in providing for urban planning land use and how to use. And the road is considered key in the historical development of the city. Consequently, they are promoting a plethora of new research and new ways of approaching the study of the relationship between road infrastructure and land use. The interest of the research project is, for all that, consider to what extent depends on the location of tertiary urban planning and changes in the road network. That is, the hypothesis of this work can be stated by saying that: the emergence of two variables affecting tertiary, urban planning and road network, of course being aware of the inherent difficulty of separating any parameters and functional relationships of an urban. Approach focusing on the particular case of the road corridor from La Coruña (N-VI) located in the west of Madrid. It is a suburban area comprising the municipalities of Las Rozas and Majadahonda, a segment of the city of Madrid (covering the districts of Aravaca, the planting and Valdemarín, and a small area of the Casa de Campo, Ciudad Universitaria and El Pardo) , and the northern half of the town of Pozuelo de Alarcón. The general conclusion has been reached is that this is a complex phenomenon, which is detected: A) The approval of a new Urban Plan is not an immediate change in the quantitative evolution of the implementation of tertiary activities in exclusive building in the study area. B) It shows a direct relationship between the introduction of a new transport infrastructure or amendment to an important and growing element of the location of tertiary activities. C) It is difficult to verify that when improvements or new construction come together in the road network and planning a strategy aimed at the management and intervention of third space, the number of commercial buildings increases.

Propuesta de aplicación de una red de sensores en emergencias

El auge y evolución de los sistemas de comunicaciones móviles y de las redes inalámbricas avanzadas, sucedido desde principios del siglo XXI, han propiciado el uso de Redes de Sensores Inalámbricos (RSI) en múltiples ámbitos de interés. Dichas redes están típicamente compuestas por dispositivos inalámbricos autónomos que incorporan sensores para la recogida de datos de distinta naturaleza. Las RSI se caracterizan por su escalabilidad, ausencia de cableado, pequeño tamaño, bajo consumo, gran variedad de magnitudes físico/químicas medibles, entre otras, cuyas cualidades las hace muy interesantes para su aplicación en multitud de escenarios de la Sociedad de la Información, tales como domótica, agricultura y ganadería, medioambiente, salud, procesos industriales, logística, seguridad o ciudades inteligentes, ente otras. En este Trabajo Fin de Máster, se propone el uso de las RSI en el escenario de Emergencias donde cobra gran importancia la usabilidad, la fiabilidad, la disponibilidad, y la robustez de los sistemas a emplear en condiciones hostiles, especialmente en las de bomberos. Es por ello que se analizarán previamente los trabajos de RSI desarrollados para estos entornos y que sugieren qué aplicaciones garantizan el cumplimiento de los requerimientos mencionados. Se aborda la utilización de una primera RSI para la monitorización ambiental de tres Centros de Procesado de Datos (CPD) del departamento de TI de Emergencias, siendo este un entorno sin movilidad, más controlado y que aporta la adquisición de experiencia en la utilización de las RSI de cara a un entorno móvil más complejo. A continuación, para el entorno móvil se ha desarrollado y validado un prototipo experimental de RSI para el seguimiento de salida de parques de bomberos de vehículos con su dotación. Así mismo se implementa un prototipo para la ayuda a la localización de bomberos y/o personas en un siniestro. Estas RSI se desarrollan e implantan en el entorno de Emergencias del Ayuntamiento de Madrid, entidad sin cuyo apoyo habría sido imposible la aplicación práctica de este trabajo. SUMMARY. The rise and evolution of mobile communication systems and advanced wireless networks in early XXI century have allowed to taking advantage of Wireless Sensor Networks (WSN). These networks are composed of independent wireless devices that incorporate sensors for collecting data of different nature. The WSN is characterized by its scalability, no wiring, small size, low power consumption, wide range of physical magnitudes measurable, among others. These qualities make them very interesting for application in many scenarios to the Information Society, such as, domotic, agriculture, smart environment, ehealth, industrial control, logistics, security and smart cities, among others. This work proposes to use WSN in the emergency scenario where is very important the usability, reliability, availability, and robustness of the systems to be used in hostile conditions, especially in fire-fighters environment. That is why WSN works in emergency will be studied to tackle what applications compliance with the above requirements. The first WSN developed will be environmental monitoring of three CPDs IT department Emergency. This scenario is a non-mobile environment, more controlled and bring gaining experience in the use of WSN to face mobile environment which is more complex. Then, for the mobile environment is developed an experimental prototype of WSN for tracking fire vehicles living fire stations with their equipment. Another prototype is foreseen to be implemented to assist fire-fighters location and / or people in a disaster. These WSN are developed and implemented for Madrid City Emergency, whose involvement was critical to put this research into stage.

El origen de Internet. El camino hacia la red de redes.

Motivación Internet es sin duda sinónimo de telecomunicaciones en este momento, es la tecnología no de futuro, sino de presente llamada a cambiar la sociedad hasta puntos insospechables, sin opción de retorno. Hoy en día ha cambiado la forma en la que nos relacionamos, la forma en la que trabajamos y la manera en que tomamos decisiones se ve fuertemente apoyada en esta herramienta. Por supuesto el devenir de la Red está por ver, los gobiernos y las grandes compañías quieren "meter mano" en el control de los contenidos, sin embargo parece que la Red sabe autogestionarse y es capaz de funcionar dentro de un modelo semi-anárquico. Objetivos El objetivo del presente proyecto es dar a conocer los orígenes de la red de redes, desarrollando un entorno social, político, económico y tecnológico para una mejor comprensión. El lector no obtendrá un extenso conocimiento técnico sobre redes y ordenadores, sin embargo será capaz de entender los verdaderos motivos que llevaron a una comunidad científica a crear la mayor herramienta para el desarrollo del ser humano. También es mi intención hacer que el lector reflexione sobre cómo influyen diferentes factores en el devenir de los hechos, momentos de grandes cambios sociales o políticos, o cómo la ciencia resuelve problemas mediante la observación o el análisis, buscando siempre la mejor opción, sin conformarse con soluciones a medias. Estructura El proyecto está estructurado en 3 grandes bloques. El primer bloque corresponde a los tres primeros capítulos que nos adentran en el tema vía una introducción a modo de punto de partida u origen del concepto, un marco histórico del período de formación de la Red y un pequeño análisis del estado del arte de los ordenadores desde sus orígenes como tal, prácticamente coetáneos con el origen de Internet. El segundo bloque narra cómo comienza el desarrollo de la Red, los pasos que se van dando y las soluciones adoptadas hasta llegar a lo que conocemos hoy día como la red de redes: Internet. Por último se detallan las conclusiones obtenidas tras la escritura de este documento, realizando una serie de reflexiones globales que me surgen tras conocer la historia de la Red. ABSTRACT. Motivation Nowadays Internet without any doubt means telecommunications. It is not the future technology but the present one and it is supposed to change the society to an unexpected point, without possibility of return. It has already changed the way we communicate each other, the way we work and also the way we take decisions are strongly hold by this tool. Meanwhile we will see the becoming of the Network, the governments and the big companies want to have the control over the contents, however it seems that the Network has the ability to self-manage and it is also capable to keep working in a semi-anarchic model. Objectives The main aim of the present project is to show what is the real origin of the network of networks, developing a social, politic, economic and technologic context of it to ensure a better comprehension. The reader won´t get an extended knowledge about computing or networking, however he or she will be able to understand the truly motivation that lead a scientific community to create the most important tool for the human development. It is also my intention to make the reader think about how different facts, depending on the moment they take place like social or political changes, can transform the way everything happens and how science solves problems by the observation and the analysis, searching always the best option, without comply with half solutions. Structure This project is divided into three sections. The first part which includes the three first chapters place us in the topic by an introduction of the concept origin, an historic context of the period of Network development and a small analysis of the state of the art in computing since its origins, which appear at the same time as the Internet. The second block explains how the development of the Net starts, the steps followed and the solutions taken until the arrival of the network of networks we all know: the Internet. Finally, we can find the conclusions, which are exposed in a reflection way, with some considerations that came to me after writing this document about the history of the Internet.
