Sistema de reservas hoteleras RESHOTEL

XXXTOUR és una empresa que té com a principal negoci fer d'intermediari per a les agències de viatge i els particulars que vulguin reservar places hoteleres, d'una banda, i per als establiments hotelers, de l'altra. Així, doncs, contracta aquestes places a uns proveïdors i les ven a aquests clients. En l'actualitat, els proveïdors comuniquen a XXXTOUR totes les dades referents a les places mitjançant documents impresos i per telèfon, i els treballadors de l'empresa les han d'introduir al sistema d'informació de l'empresa. Per mitjà del nou sistema, els proveïdors, a més de poder emprar la funcionalitat actual, podran accedir al portal d'XXXTOUR i introduir les seves pròpies dades. I quan rebin una petició de places les podran confirmar accedint al portal, de manera que el client tindrà les places sol·licitades molt més aviat, cosa que millora el servei.

Tecnologia .NET : Hotel SPA

Treball de Fi de Carrera sobre la tecnologia .NET de Microsoft. En aquest treball s'ha creat un servei WCF i una petita aplicació de consola per hostatjar-lo. Aquest servei utilitza unes classes de LINQ To SQL per accedir a la base de dades. L'aplicació HotelSpaWPF, creada amb WPF i XAML, consumeix el servei WCF per treballar amb la informació de que es disposa a la base de dades.L'aplicació d'escriptori HotelSpaWPF consta de dues parts, la part corresponent als clients de l'hotel, on podran consultar el serveis, activitats i recursos oferts així com fer peticions, inscripcions o reserves. La part d'administrador permet gestionar tota aquesta informació.

Detection of Onchocerca volvulus (Nematoda: Onchocercidae) infection in vectors from Amazonian Brazil following mass Mectizan™ distribution

Detection of Onchocerca volvulus in Simulium populations is of primary importance in the assessment of the effectiveness of onchocerciasis control programs. In Brazil, the main focus of onchocerciasis is in the Amazon region, in a Yanomami reserve. The main onchocerciasis control strategy in Brazil is the semi-annually mass distribution of the microfilaricide ivermectin. In accordance with the control strategy for the disease, polymerase chain reaction (PCR) was applied in pools of simuliids from the area to detect the helminth infection in the vectors, as recommended by the Onchocerciasis Elimination Program for the Americas and the World Health Organization. Systematic sampling was performed monthly from September 1998 to October 1999, and a total of 4942 blackflies were collected from two sites (2576 from Balawaú and 2366 from Toototobi). The molecular methodology was found to be highly sensitive and specific for the detection of infected and/or infective blackflies in pools of 50 blackflies. The results from the material collected under field conditions showed that after the sixth cycle of distribution of ivermectin, the prevalence of infected blackflies with O. volvulus had decreased from 8.6 to 0.3% in Balawaú and from 4 to 0.1% in Toototobi.

Exposure of free-ranging wild carnivores, horses and domestic dogs to Leptospira spp in the northern Pantanal, Brazil

Leptospirosis is a zoonotic disease affecting most mammals and is distributed throughout the world. Several species of domestic and wild animals may act as reservoirs for this disease. The purpose of this study was to assess the exposure of free-ranging wild carnivores, horses and domestic dogs on a private reserve located in the northern Pantanal (Brazil) and the surrounding areas to Leptospira spp from 2002-2006, 75 free-ranging wild carnivores were captured in the Pantanal and serum samples were collected. In addition, samples from 103 domestic dogs and 23 horses in the region were collected. Serum samples were tested for the presence of Leptospira antibodies using the microscopic agglutination test. Thirty-two wild carnivores (42.7%) were considered positive with titres > 100, and 18 domestic dogs (17.5%) and 20 horses (74.1%) were also found to be positive. Our study showed that horses, dogs and several species of free-ranging wild carnivores have been exposed to Leptospira spp in the Pantanal, suggesting that the peculiar characteristics of this biome, such as high temperatures and an extended period of flooding, may favour bacterial persistence and transmission. In this region, wild carnivores and horses seem to be important hosts for the epidemiology of Leptospira species.

Ecological and land use studies along elevational gradients

Mountain regions and UNESCO Mountain Biosphere Reserves (MBRs) encapsulate broad elevational ranges, cover large gradients of geological, topographical and climatic diversity, and thus host greater biodiversity than the surrounding lowlands. Much of the biological richness in MBRs results from the interaction of climatic contrasts and gravitational forces along elevational gradients. External forces such as atmospheric change and human land use interact with these gradients, and result in distinct landscape patchiness, ie mosaics of land cover types within and across elevational belts. The management of MBRs influences land use and land cover, which affects biodiversity and ecosystem processes, both of which provide goods and services to society. Due to their broad environmental and biological diversity, MBRs are ideally suited for global change research and will be increasingly important in illustrating biodiversity conservation. This article summarizes the ecologically relevant results of an international workshop on elevational gradients that aimed to achieve a synthesis of the major ecosystem and biodiversity conditions and drivers in an altitude context. The workshop developed a core research agenda for MBRs that prioritizes long-term research and changes in land use across a broad elevational range.

Effect of major hepatectomy on glucose and lactate metabolism.

BACKGROUND: The liver plays an important role in glucose and lactate metabolism. Major hepatectomy may therefore be suspected to cause alterations of glucose and lactate homeostasis. METHODS: Thirteen subjects were studied: six patients after major hepatectomy and seven healthy subjects who had fasted overnight. Glucose turnover was measured with 6,6(2)H glucose. Lactate metabolism was assessed using two complementary approaches: 13C-glucose synthesis and 13CO2 production from an exogenous 13C-labeled lactate load infused over 15 minutes were measured, then the plasma lactate concentrations observed over 185 minutes after lactate load were fitted using a biexponential model to calculate lactate clearance, endogenous production, and half-lives. RESULTS: Three to five liver segments were excised. Compared to healthy controls, the following results were observed in the patients: 1) normal endogenous glucose production; 2) unchanged 13C-lactate oxidation and transformation into glucose; 3) similar basal plasma lactate concentration, lactate clearance, and lactate endogenous production; 4) decreased plasma lactate half-life 1 and increased half-life 2. CONCLUSIONS: Glucose and lactate metabolism are well maintained in patients after major hepatectomy, demonstrating a large liver functional reserve. Reduction in the size of normal liver parenchyma does not lead to hyperlactatemia. The use of a pharmacokinetic model, however, allows the detection of subtle alterations of lactate metabolism.
