Flight Delays, Security and Economic Reimbursements

Over the past decade, the air transport system has undergone profound changes, mainly driven by the evolution of reference legislation and markets globalization process. The primary cause also goes by the name of "deregulation", which has profoundly revolutionized the tariff methodology and air transport management.With deregulation, airlines have seen disappear of barriers and constraints that incentivized growth and development for many years (Arrigo, Giuricin, 2006; Postorino, 2009).The globalization of markets has also proved decisive in the growth of demand for air transport, which has become an irreplaceable means of transfer that allows the connection from one part of the terrestrial globe to another in a few hours. Impressive growth in air traffic and deregulation has at the same time led to millions of frequent passengers and unpleasant complications, such as delays. In the absence of a specific discipline in this area and with the desire to give balance to a situation partially unbalanced to the detriment of consumers/travelers, the European Union decided to take action to remedy it, equipping passengers with effective protection tools against these afore mentioned situations.The European Union has made the rules issued in 1991 on compensation and assistance to air passengers more rigid and afflictive for airlines by providing, at the same time, new provisions aimed at mitigating the inconvenience of passengers abandoned at airports due to canceled flights or of prolonged delays. The EU legislation covering these changes, which was preceded by the Passenger Rights White Paper, is contained in EU Regulation 261/1994, which came into force in February 2005, which sets out how and operational rules on assistance and reimbursement to air traffic users (Fraschina, 2009).The three different hypotheses of "denied boarding", cancelled flights and prolonged delays are the subject of regulation.In this study, however, we will mainly address the rights and reimbursement of passengers in the event of delays of air flights, in fact according to the new legislation, more protection will be provided to passengers who will face the painful and common circumstances of the delays. Community bodies believed that adequate assistance and reimbursement should be provided to passengers who were forced to long waits at airports due to a flight delay.

A Model of the Universe in Kathmandu's Old Royal Palace

This paper discusses a model of the universe found in Mohan courtyard of the old royal palace of Kathmandu, the Hanumānḍhokā. It was commissioned and installed by King Pratāpa Malla in 1656 CE. The artifact is referred to as “earth-ball” or terrestrial globe (bhūgola) in an inscription and is based on Purāṇic concepts of the universe. An eighteenth-century ritual text indicates that it was an object of worship in the courtyard.

Utilisation De L’image Multispectrale Pour L’exploration Et La Recherche Des Ressources Minérales : État Des Connaissances Et Proposition D’un Modèle De Traitement

Multiband space remote sensing is an indirect tool for prospecting the Earth's surface. It is very powerful especially in its applications related to the field of geology including geological mapping, mining and oil exploration. It can also significantly reduce the cost of exploration, reach inaccessible areas, guide mining research to favorable regions and reach a large surface. In this article, we highlight in details the state of knowledge in this field of research by citing the different methods and approaches carried out by several specialists who generally define the use of remote sensing for lithostructural and mineralogical mapping and particularly for the exploration and research of mineral substances. We also create methods derived from the aforementioned methods of treatment by means of a logical analogy between the different bands of several satellites of observation of the terrestrial globe, particularly between : Landsat 7 ETM +; Landsat 8 OLI / TIRS; Aster and Sentinel 2A. At the end, we synthesize these results by proposing a multispectral image-processing model that can be applied directly. This model starts with the calculation of Optimum Index Factor (OIF), which allows us to detect only the most important colored composites; and the reports of the bands, rations, the principal component analysis, ACI and the classification that allow the realization of a lithological and mineralogical mapping as well as maps of lineaments by means of directional filters. The validity of the models is tested by comparison with field data and geological maps of the studied site.

Global Assessment of the Standardized Evapotranspiration Deficit Index (SEDI) for Drought Analysis and Monitoring

This article developed and implemented a new methodology for calculating the standardized evapotranspiration deficit index (SEDI) globally based on the log-logistic distribution to fit the evaporation deficit (ED), the difference between actual evapotranspiration (ETa) and atmospheric evaporative demand (AED). Our findings demonstrate that, regardless of the AED dataset used, a log-logistic distribution most optimally fitted the ED time series. As such, in many regions across the terrestrial globe, the SEDI is insensitive to the AED method used for calculation, with the exception of winter months and boreal regions. The SEDI showed significant correlations ( p < 0.05) with the standardized precipitation evapotranspiration index (SPEI) across a wide range of regions, particularly for short (<3 month) SPEI time scales. This work provides a robust approach for calculating spatially and temporally comparable SEDI estimates, regardless of the climate region and land surface conditions, and it assesses the performance and the applicability of the SEDI to quantify drought severity across varying crop and natural vegetation areas.

Precision study of satellite levelling with using various models of geoid

The main purpose of this study is comparison of orthometric heights of measuring points and the accuracy of these heights depending on selected geoid model and measurement method. In addition, for better understanding of the essence of conducted research, paper provides information about: geoid and other surfaces used in geodesy to describe the terrestrial globe, modelling methods of equipotential surfaces and data that can be used to develop them, the most important geoid models developed for the area of Poland and the world, the technique of determining the orthometric heights using various measuring methods. Heights of two measuring points, located on the premises of Wrocław University of Science and Technology, were determined to achieve thesis statement.

The differential diagnostic of anemias associated with iron metabolism

The iron-deficiency conditions continue to be an actual problem all over the world being present in half of population of the terrestrial globe. The development of iron deficiency often depends on gender and age. In females specific role is played by hypermenorrhea and repeated pregnancies (iron deficiency and iron-deficiency anemia are found 6 times more often in females than in males). The anemia of chronic diseases by it prevalence takes second place after iron-deficiency anemia. The prevalence of anemia of chronic diseases in elder and senile age varies within range 2,9-61% in males and 3,3-41% in females. In young and mature age anemia of chronic diseases more often occurs in females. There are anemias when content of iron in organism and its resources are within limits of norm or higher - sideroahrestical anemias. The percentage of them in structure of hypochromic anemias is smallish. The diagnostic and differential diagnostic of anemias related to iron metabolism. The anemias are diverse according to clinical hematological characteristics. At selection of diagnostic schemes, treatment of anemias differs on leading pathogenic mechanism. However, to facilitate diagnostic and differential diagnostic the color indicator and morphological classifications are considered. The differentiated diagnostic of anemias is based on data of clinical, laboratory and instrumental analysis. The blood analysis under anemia is to take into account indices of Hb, size of erythrocytes, their saturation with Hb, average volume of erythrocytes, and average content of hemoglobin in erythrocytes, amount of reticulocytes and other cells permitting judging about character and activity of erythropoiesis. The article presents algorithm of examination of patient under hypochromic and microcytic anemia, diagnostic and differentiated diagnostic of acute post-hemorrhagic anemia, anemia of chronic course, iron-deficiency anemia, anemia of chronic diseases, sideroahrestical anemia, iron-saturated anemia due to leaden intoxication, inherent iron-saturated anemia of pharmaceutical genesis, thyroprival anemia and thalassemia.

Emergency Planning for Records and Archives Service

Every day we are witnessing the destruction of archival documents in all the terrestrial globe as a result of disasters such as earthquakes, floods, fires, war etc. These adversities have raised awareness of archivists to do anything to protect archival documents, because these disaster at any moment can slam their institution. In order to protect themselves and their assets, including records and archives, many organizations develop “emergency plans”. An emergency plan seeks to protect people and property and ensure that, in the event of an emergency, action is taken immediately to reduce the damage incurred and institute recovery procedures right away. A risk assessment and impact analysis is usually carried out in four stages: identifying records and assets, determining threats, assessing their impact and recommending action.
