Doctoral: A smartphone-based decision support tool for the early detection of oral potentially malignant disorders
2023
Oral potentially malignant disorders can be defined as mucosal lesions and conditions with an increased risk of malignant transformation. Oral potentially malignant disorders are a significant health burden, and they are often diagnosed late due to scant attention to routine dental practice and the low number of specialized oral medicine centres. This report summarizes the DoctOral experience, a research initiative, providing a free smartphone-based decision support tool for the general medical/dental practitioner; the tool is based on the clinical appearance of oral lesions. Captured, oral pictures can be immediately examined via interactive decision trees and constructed on the smartphon…
Smoking cessation opportunities in severe mental illness (tobacco intensive motivational and estimate risk — TIMER—): study protocol for a randomized…
2019
There is an increased risk of premature death in people with severe mental illness (SMI). Respiratory disorders and cardiovascular disease are leading causes of increased mortality rates in these patients, and tobacco consumption remains the most preventable risk factor involved. Developing new tools to motivate patients towards cessation of smoking is a high priority. Information on the motivational value of giving the lung age and prevention opportunities is unknown in this high-risk population. In the context of community care, screening and early detection of lung damage could potentially be used, together with mobile technology, in order to produce a prevention message, which may provi…
Are smartphone applications (App) useful to improve hearing?
2020
Le App per smartphone possono essere utili per migliorare l’udito?L’obiettivo dello studio è quello valutare l’efficacia di un’App per smartphone creata con lo scopo di migliorare le performance uditive sia in soggetti normoudenti che in pazienti affetti da ipoacusia da lieve a severa. Si tratta di uno studio analitico multicentrico, eseguito tra giugno e dicembre 2017, che ha analizzato un campione di 68 pazienti di cui 55 ipoacusici e 13 normoudenti; a tutti i pazienti sono stati somministrati test audiologici specifici sia durante l’utilizzo della suddetta App che in assenza di ausili uditivi. Il protocollo di valutazione audiologica prevedeva l’esecuzione di un’audiometria tonale limina…
Studies of malformation syndromes of man XIB: the cerebro-hepato-renal syndrome of zellweger: Comparative pathology
1976
A study of 11 autopsied cases of the cerebro-hepato-renal syndrome of Zellweger (ZS) is reported. All cases had severe, persistent congenital hypotonia, hepatic lobular disarray, renal cortical cysts and pulmonary hypoplasia. Many had cardiovascular malformations, hepatomegaly, cerebral cortical gyral maldevelopment and pancreatic islet hyperplasia. Additional, less frequent findings are delineated. Results of iron content studies of hepatic and renal tissues are related to age of survival and possible development of fibrosis.
Liver Involvement in Hodgkin's Lymphoma: Types of Injuries and Therapeutic Implications
2017
The hepatocytolysis raises questions on following therapeutic conduct when it occurs during chemotherapy for Hodgkin's lymphoma, expression of its liver toxicity. But the onset of primary liver Hodgkin's lymphoma, including the form manifested by acute liver failure, poses even greater problems, as in the case of occurrence of vanishing bile duct syndrome - expression of a paraneoplastic syndrome, hemophagocytic lymphohistiocytosis, peliosis hepatis or association of lymphoma with infection with hepatitis viruses or human immunodeficiency virus or different autoimmune diseases. This review summarizes the clinical experience acquired on the relationship between Hodgkin's lymphoma and liver, …
Decoupled Downlink-Uplink Coverage Analysis with Interference Management for Enriched Heterogeneous Cellular Networks
2016
Heterogeneous cellular networks (HetCNets) offer a promising solution to cope with the current cellular coverage crunch. Due to the large transmit power disparity, while following maximum power received (MPR) association scheme, a larger number of users are associated with macro-cell BS (MBS) than small-cell BSs (SBSs). Therefore, an imbalance load arrangement takes place across the HetCNets. Hence, using cell range expansion-based cell association, we can balance the load across the congested MBS. However, using MPR association scheme, users’ offloading leads to two challenges: 1) macro-cell interference , in which the MBS interferes with the offloaded users, and 2) coupled downlink-uplink…
Analysis of load balancing and interference management in heterogeneous cellular networks
2017
To meet the current cellular capacity demands, proactive offloading is required in heterogeneous cellular networks (HetCNets) comprising of different tiers of base stations (BSs), e.g., small-cell BSs (sBSs) and conventional macro-cell BSs (mBSs). Each tier differs from the others in terms of BS transmit power, spatial density, and association bias. Consequently, the coverage range of each tier BSs is also different from others. Due to low transmit power, a fewer number of users are associated to an sBS as compared with mBS. Thus, inefficient utilization of small-cell resources occurs. To balance the load across the network, it is necessary to push users to the underloaded small cells from …
Fomento del Mobile Learning en educación alrededor de la última década. Un estudio de caso en españa través de una selección de aportaciones.
2020
En la actualidad educativa las TIC han propiciado de manera inevitable el uso de los dispositivos móviles en el aula y en concreto del teléfono móvil como herramienta educativa. Desde hace años se desarrolla literatura al respecto y se han llevado a cabo proyectos y actividades educativas que lo promocionan. Se trata de una de las metodologías educativas emergentes que ha ido en aumento paulatinamente, se va integrando en la escuela tímidamente y, en algunos casos, con ciertos prejuicios sobre su uso. El siguiente escrito aborda el desarrollo del Mobile Learningo Aprendizaje en Movilidad en la segunda década del siglo XXI en el Estado Español. Damos cuenta de la divulgación científica acont…
MINE - Mobile Learning in Higher Education
2018
Mobile technologies are an important part of our daily life and we carry them with us all the time. Mobile learning is already used a lot in informal and non-formal learning, but in the context of formal learning it is not much used, yet. In the area of formal learning at universities, there is a great need for pedagogic scenarios to encourage educatorsto use these new technologies. It is suggested that educators will need to move beyond the didactic approaches still frequently found in higher education. Social constructivist approaches have been advocated, along with the development of communities of practice to support educators. In addition, more emphasis on learners is required, to unde…
Optimization of vehicle-trailer connection systems
2016
The three main requirements of a vehicle-trailer connection system are: en route stability, over- or under-steering restraint, minimum off-tracking along curved path. Linking the two units by four-bar trapeziums, wider stability margins may be attained in comparison with the conventional pintle-hitch for both instability types, divergent or oscillating. The stability maps are traced applying the Hurwitz method or the direct analysis of the characteristic equation at the instability threshold. Several types of four-bar linkages may be quickly tested, with the drawbars converging towards the trailer or the towing unit. The latter configuration appears preferable in terms of self-stability and…
