Endpoint Admission Control over Assured Forwarding PHBs and Its Performance over RED Implementations
2001
The Assured Forwarding Per Hop Behavior (AF PHB) has been devised by the IETF Differentiated Services (DiffServ) working group to provide drop level differentiation. The intent of AF is to support services with different loss requirements, but with no strict delay and jitter guarantees. Another suggested use of AF is to provide differentiated support for traffic conforming to an edge conditioning/policing scheme with respect to nonconforming traffic. Scope of this paper is twofold. First, we show that, quite surprisingly, a standard AF PHB class is semantically capable of supporting per flow admission control. This is obtained by adopting the AF PHB as core routers forwarding mechanism in c…
PCP: An End-to end Measurement Based Call Admission Control for Real-Time Services Over IP Networks
2000
Distributed end-to-end measurement based connection admission control mechanisms have been recently proposed. The goal of these schemes is to provide tight QoScon trol on a per connection basis by means of measurements taken by the edge nodes and priority based forwarding procedure at internal nodes. Since the additional flows handling procedures are implemented at the border routers and the forwarding mechanisms are for flows aggregates only, the approach is fully scalable and compatible with the IETF Differentiated Service proposal. The aim of this paper is to propose specific schemes and to investigate the advantages and limits of the approach by analyzing the basic mechanisms and evalua…
Identitats de gènere i esport. Masculinitats inductores i resistències a la masculinitat hegemònica al futbol espanyol.
2010
Com a contribució al recorregut històric de la Psicologia social, s'aborda ara el decurs d'un esport universal i l'atribució a un dels gèneres: el masculí, evidentment. L'autor es pregunta si s'ha produït algun canvi en el ethos de gènere del futbol com a conseqüència de la pròpia evolució de les relacions de gènere en la societat espanyola i en relació amb el que s'ha denominat la crisis de la masculinitat. I mira de contestar a abastament, en el contingut del seu detallat i documentat estudi, que es divideix en cinc parts. En la primera s'ofereix una revisió de la literatura sobre la qüestió i es desenvolupa el marc teòric en el qual es recolza la investigació presentada, en les tres segü…
Live free or die motionless : Walking the migrant path from Italy to France
2018
This essay and the photographs examine visual traces of irregular mobility in the border landscape between Italy and France. The ruined buildings and objects witness decades of movement of undocumented people on this old migrant path across the mountains. By taking the theoretical concept of multidirectional memory (Rothberg 2009) the essay argues that the Path of Hope can be thought of as a memory site through which the issues of migration in contemporary Europe can be seen in a more sustainable light. The ruins and discarded objects link memories of different places – including different border zones – in ways that allow us to critically examine borders as a practice – rather than as exis…
THE ROUTE OF THE HOLY GRAIL: FROM SAN JUAN DE LA PEÑA TO VALENCIA. THE STRUCTURING OF A TERRITORY BASED ON ORAL TRADITION
2018
The Route of the Holy Grail was presented FITUR 2017 (Madrid, January 2017) by the Agència Valenciana del Turisme. It involves structuring a routethat connects the communities of Aragon and Valencia by use of touristic description that encompasses history, art, rituals and oral traditions and which is based on the knowledge of what was known in the Middle Ages as the “search for the Grail”. In this article we wish to show the importance of the oral tradition that has been received and perpetuated through an object of fundamental importance: the Holy Chalice, safeguarded in the Cathedral of Valencia. In addition to presenting its history and verifying it as a tangible patrimonial asset, the …
Microfibrillar polymeric ocular inserts for triamcinolone acetonide delivery.
2019
Abstract Despite eye drops generally represent the most convenient, simple and patient-friendly formulations to treat ocular diseases, they suffer from poor retention on the ocular surface and low drug bioavailability leading to the necessity of prolonged and continuous treatment over time. Therefore, ocular insert could represent an innovative way to benefit from ocular topical administration while minimizing all the relevant limitation related to this route of administration. Polymeric non-erodible mucoadhesive ocular inserts should be comfortable and should rapidly adhere on the ocular surface, remain in situ for prolonged period, assure a reproducible and controlled drug release as well…
Human buccal mucosa as an innovative site of drug delivery.
2009
The authors review the ultra-structural aspects and permeability features of normal human oral mucosa, after having recently tested and used it as a new site of systemic drug delivery. The pertinent scientific literature from 1975 through 2009 has been analysed and discussed. Buccal epithelium is a relatively permeable, robust non-keratinized tissue and blood vessels drain directly into the jugular vein; due to its particular features, it has been of increasing interest to researchers as an alternative site of drug administration. The review describes the structure and function of the buccal mucosa, the rationale for transbuccal drug delivery and the main transmucosal drug delivery systems.…
Zugangswege f�r die Medikamentenapplikation bei Herzkreislaufstillstand
1996
Selecting a route for drug administration during CPR requires consideration of the speed with which access can be obtained, the technical difficulties involved in performing the procedure, the associated risk of complications, delays in drug delivery to the central circulation, and the duration of effective drug levels following injection. The peripheral venous route is the safest method, and drug delivery can be enhanced by a fluid bolus after injection of the medication. The circulation time is shortest after central venous injection, but there is some risk of complications. The femoral route is associated with a high incidence of unsuccessful catherization. The endotracheal tube provides…
Recent progress in the pharmacotherapy of cancer pain.
2001
Cancer pain can be relatively well managed with primary therapies, according to the WHO ladder. However, different conditions may limit the response to the analgesic drug used, which are mainly oploids. Specifically, adverse effects may prevail against the analgesic activity in the clinical setting. New pharmacological strategies may enable a more satisfactory response to be obtained, in terms of balance between analgesia and adverse effects. The change of route of administration or the use of alternative opioids is a first-line option. The use of adjuvant drugs may also improve analgesia with different mechanisms. Recent studies have demonstrated the value of these alternative approaches. …
Inhalation therapy devices for the treatment of obstructive lung diseases: the history of inhalers towards the ideal inhaler.
2020
Inhalation therapy allows conveying drugs directly into the airways. The devices used to administer inhaled drugs play a crucial role in the management of obstructive lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). To ensure high bronchial deposition of the drug, a device should deliver a high proportion of fine particles, be easy to use, and provide constant and accurate doses of the active substance. Nowadays, four different types of inhalers are widely used: nebulizers, dry powder inhalers (DPIs), pressurized metered-dose inhalers (pMDIs), and soft mist inhalers (SMIs). Nebulizers can be used by patients unable to use other inhalers. However, they require l…
