Inflammation and sarcopenia: A systematic review and meta-analysis
2017
Inflammatory cytokines have been shown to prompt muscle wasting, ultimately stimulating protein catabolism and suppressing muscle synthesis. However, the possible association between inflammatory parameters and sarcopenia is poorly understood. We therefore aimed to summarize the current evidence about this topic with a meta-analysis of studies reporting serum inflammatory parameters in patients with sarcopenia vs. people without sarcopenia (controls). An electronic PubMed and Scopus search through to 09/01/2016 and meta-analysis of cross-sectional studies comparing serum levels of inflammatory cytokines between patients with sarcopenia and controls was made, calculating random-effects stand…
A Forecasting Support System Based on Exponential Smoothing
2010
This chapter presents a forecasting support system based on the exponential smoothing scheme to forecast time-series data. Exponential smoothing methods are simple to apply, which facilitates computation and considerably reduces data storage requirements. Consequently, they are widely used as forecasting techniques in inventory systems and business planning. After selecting the most adequate model to replicate patterns of the time series under study, the system provides accurate forecasts which can play decisive roles in organizational planning, budgeting and performance monitoring.
Meta-analysis of time perception and temporal processing in schizophrenia: Differential effects on precision and accuracy
2016
Numerous studies have reported that time perception and temporal processing are impaired in schizophrenia. In a meta-analytical review, we differentiate between time perception (judgments of time intervals) and basic temporal processing (e.g., judgments of temporal order) as well as between effects on accuracy (deviation of estimates from the veridical value) and precision (variability of judgments). In a meta-regression approach, we also included the specific tasks and the different time interval ranges as covariates. We considered 68 publications of the past 65years, and meta-analyzed data from 957 patients with schizophrenia and 1060 healthy control participants. Independent of tasks and…
Quasi-Modes and Spectral Instability in One Dimension
2019
In this section we describe the general WKB construction of approximate “asymptotic” solutions to the ordinary differential equation $$\displaystyle P(x,hD_x)u=\sum _{k=0}^m b_k(x)(hD_x)^ku=0, $$ on an interval α < x < β, where we assume that the coefficients bk ∈ C∞(]α, β[). Here h ∈ ]0, h0] is a small parameter and we wish to solve (above equation) up to any power of h. We look for u in the form $$\displaystyle u(x;h)=a(x;h)e^{i\phi (x)/h}, $$ where ϕ ∈ C∞(]α, β[) is independent of h. The exponential factor describes the oscillations of u, and when ϕ is complex valued it also describes the exponential growth or decay; a(x;h) is the amplitude and should be of the form $$\displaystyle a(x;h…
Oral Health-Related Quality of Life in institutionalized elderly in Barcelona (Spain).
2012
Objective: The objective of this study is to describe the oral health status and the factors associated with oral health-related quality of life (OHRQoL) in people aged 65 and older institutionalized in Barcelona in 2009. Study Design: Cross sectional study in 194 elderly. The dependent variable was poor OHRQoL, according to the Geriatric Oral Health Assessment Index (GOHAI). The independent variables were socio-demographic data, last dental visit, subjective and objective oral health status. Robust Poisson regression analysis was used to determine the factors associated with OHRQoL as well as the strengths of association (Prevalence Ratios with respective confidence intervals at 95%). Resu…
On the packing sums of pairs
1993
Abstract This paper is concerned with the determination of the length of the largest interval of consecutive integers of the set hA k , where A k is a sequence of integers which is a B h -sequence.
A Logical Explication of the Concepts of Incomplete and Uncertain Information
1994
Discovery of elementary knowledge and its constituents, i.e. information contained in objects of reality is realized through asking questions including certain aspects called attributes in this paper. We describe a fragment of a discovered reality as an information system (cf. Pawlak [1,3,4]), which consists of the universum U of all the objects of this reality we are concerned with, and of a set A of attributes understood as functions each of which assigns to every object of U 1) a value of given attribute belonging to A or 2) an interval of approximate values of this attribute, i.e. an established set of possible values of this attribute. From the point of view of the cognitive agent and …
The effects of different milking intervals and milking times per day in jennet milk production
2012
Abstract In their first 150 days of lactation, nine Ragusana jennets were investigated at the ‘Istituto Sperimentale Zootecnico per la Sicilia’ (ISZS) in Palermo, to study the effects of different milking typologies on milk production. The jennets were kept in a paddock and were fed hay ad libitum and concentrate (3.5 kg jennet/day). From post-foaling day 21, every 3 weeks individual milk amounts were recorded, and individual milk samples were collected and analyzed for the main qualitative parameters. The compared theses were: two daily milking times with 6- and 3-h intervals; and two, three and eight daily milking times with 3-h interval. The jennets were manually milked. The foals were s…
VALUTAZIONE DEL LIVELLO DI RIEMPIMENTO DELLA MAMMELLA D’ASINA A DIVERSI INTERVALLI DI MUNGITURA
2013
Scopo del presente lavoro è stato quello di valutare il livello di riempimento della mammella d’asina a diversi intervalli di mungitura per definire il numero di mungiture giornaliere e il relativo intervallo che, nel rispetto della fisiologia della mammella dell’asina e del benessere animale, permettano di migliorare la produzione di latte. Durante lo studio differenti controlli batteriologici sono stati effettuati per verificare la qualità igienica del latte, considerando la principale destinazione del latte all’alimentazione dei lattanti affetti da Allergia alle Proteine del Latte Vaccino. Lo studio è stato condotto su 12 asine Ragusane pluripare in lattazione nel novembre 2011 presso l’…
La Sicilia negli Orsi di Dino Buzzati e Lorenzo Mattotti
2022
Nella fiaba illustrata di Dino Buzzati La famosa invasione degli orsi in Sicilia (1945) e nella sua trasposizione filmica ad opera di Lorenzo Mattotti (2019) l’ambientazione siciliana è determinante. In entrambi i casi la Sicilia è un’isola con un grande vulcano – trasfigurata in un ambiente fantastico o riscritta secondo alcuni stereotipi – che i due autori utilizzano con accezioni diverse nella costituzione dell’ecosistema delle loro narrazioni. Soltanto attraverso una comparazione tra le due opere sarà possibile distinguere la rappresentazione delle due Sicilie che vengono raccontate con un intervallo di circa settanta anni. Se non si considera la storia degli Orsi soltanto una fiaba per…
