La compra silenciosa. Arrendamientos, estabilidad y mejoras en la agricultura valenciana de regadío (1850–1930)
2007
Resumen Este articulo analiza como fue posible, en el regadio valenciano, un desarrollo agrario basado en el arrendamiento de pequenas explotaciones. Del estudio de los contratos firmados en la huerta de Gandia se deduce, en primer lugar, que los arrendatarios ocupaban la parcela durante un periodo bastante prolongado de tiempo, que tendio a crecer durante la segunda mitad del siglo XIX; y, en segundo, que a menudo los cultivadores eran indemnizados al finalizar su contrato por las mejoras que habian introducido. A largo plazo, todo ello consolido su posicion, porque el cultivador se convirtio en “semipropietario” de hecho de la tierra mejorada. Por su parte, los terratenientes rentistas ob…
Validation of the 2009 TNM Version in a Large Multi-Institutional Cohort of Patients Treated for Renal Cell Carcinoma: Are Further Improvements Neede…
2010
Background: A new edition of the TNM was recently released that includes modifications for the staging system of kidney cancers. Specifically, T2 cancers were subclassified into T2a and T2b ( 10 cm), tumors with renal vein involvement or perinephric fat involvement were classified as T3a cancers, and those with adrenal involvement were classified as T4 cancers. Objective: Our aim was to validate the recently released edition of the TNM staging system for primary tumor classification in kidney cancer. Design, setting, and participants: Our multicenter retrospective study consisted of 5339 patients treated in 16 academic Italian centers. Intervention: Patients underwent either radical or part…
Global, regional, and national progress towards Sustainable Development Goal 3.2 for neonatal and child health: all-cause and cause-specific mortalit…
2021
Background: Sustainable Development Goal 3.2 has targeted elimination of preventable child mortality, reduction of neonatal death to less than 12 per 1000 livebirths, and reduction of death of children younger than 5 years to less than 25 per 1000 livebirths, for each country by 2030. To understand current rates, recent trends, and potential trajectories of child mortality for the next decade, we present the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 findings for all-cause mortality and cause-specific mortality in children younger than 5 years of age, with multiple scenarios for child mortality in 2030 that include the consideration of potential effects of COVID-…
PERFORMANCE ENHANCEMENT OF VAPOUR COMPRESSION REFRIGERATION SYSTEMS USING NANOPARTICLES: AN EXPERIMENTAL STUDY
2019
In recent years, the development and characterization of new refrigerants with higher energetic efficiency have gained considerable interest [1], with a particular emphasis on the energetic performance of suitable replacements. Nanofluids have been proposed as possible alternative due to their role in enhancing the thermophysical proprieties of traditional refrigerants [2]. The comprehensive review in [2] suggests that thermal conductivity of nanofluid increases with temperature and volume concentration but it is dependent on nanoparticle size distribution; specific heat is also increased if nanoparticles are added to the refrigerant. As consequence, the improved heat transfer coefficients …
Noncooperative dynamic games for inventory applications: A consensus approach
2008
We focus on a finite horizon noncooperative dynamic game where the stage cost of a single player associated to a decision is a monotonically nonincreasing function of the total number of players making the same decision. For the single-stage version of the game, we characterize Nash equilibria and derive a consensus protocol that makes the players converge to the unique Pareto optimal Nash equilibrium. Such an equilibrium guarantees the interests of the players and is also social optimal in the set of Nash equilibria. For the multi-stage version of the game, we present an algorithm that converges to Nash equilibria, unfortunately not necessarily Pareto optimal. The algorithm returns a seque…
Introduction to coronary imaging with 64-slice computed tomography
2005
The aim of this article is to illustrate the main technical improvements in the last generation of 64-row CT scanners and the possible applications in coronary angiography. In particular, we describe the new physical components (X-ray tube-detectors system) and the general scan and reconstruction parameters. We then define the scan protocols for coronary angiography with the new generation of 64-row CT scanners to enable radiologists to perform a CT study on the basis of the diagnostic possibilities.
"McDonald's" lietotnes uzlabošanas iespējas
2021
Bakalaura darba tēma ir “McDonald’s” lietotnes uzlabošanas iespējas”. Bakalaura darba mērķis ir izpētīt esošo “McDonald’s” mobilo lietotni, izstrādāt priekšlikumus kā uzlabot lietotni, lai vairāk pievērst uzmanību lietotnei un vēl vairāk palielināt klientu skaitu. Darbs sastāv no četrām nodaļām. Pirmajā nodaļa tiek analizēta SIA “Premier Restaurants Latvia”, uzņēmuma biznesa procesi un lietotnes ietekme uz tiem. Otrajā nodaļā tiek raksturota esošā mobilā lietotne un analizēti lietotnes statistiskie dati. Trešajā nodaļā tiek analizēta cilvēku aptauja par “McDonald’s” lietotnes uzlabošanas iespējam. Ceturtajā nodaļā tiek izvirzīti priekšlikumi “McDonald’s” mobilās lietotnes uzlabošanā. Bakala…
