Reducing postharvest decay in cactus pears by dip treatment with imazalil or azoxystrobin
2019
Postharvest decay in cactus pear is a minor problem in fruit marketed directly after harvest, while it may represent a major cause of losses when fruit are cold stored or subjected to cold quarantine treatments. Unfortunately, to date, no postharvest fungicide has been registered to control postharvest decay of cactus pears. Thus, the objective of this study was to evaluate the efficacy of two globally known fungicides, imazalil (IMZ) and azoxystrobin (AZO), registered for postharvest treatment of various fresh produce species, to control decay on cactus pears. Second-crop cactus pears ‘Gialla’ fruits were dipped in 500 mg L(‑1) IMZ or AZO and stored at 1 or 8°C and 90-95% RH for 2 or 3 wee…
Five times sit-to-stand test in subjects with total knee replacement: Reliability and relationship with functional mobility tests
2017
The objective was to determine the inter-observer and test/retest reliability of the "Five-repetition sit-to-stand" (5STS) test in patients with total knee replacement (TKR). To explore correlation between 5STS and two mobility tests. A reliability study was conducted among 24 (mean age 72.13, S.D. 10.67; 50% were women) outpatients with TKR. They were recruited from a traumatology unit of a public hospital via convenience sampling. A physiotherapist and trauma physician assessed each patient at the same time. The same physiotherapist realized a 5STS second measurement 45-60min after the first one. Reliability was assessed with intraclass correlation coefficients (ICCs) and Bland-Altman plo…
An Optoelectronic System for Measuring the Range of Motion in Healthy Volunteers: A Cross-Sectional Study.
2019
Background and Objectives: Within the clinical evaluation of multiple pathologies of the lower limb, the measurement of range of motion (ROM) of its joints is fundamental. To this end, there are various tools, from the goniometer as a reference to more recent devices such as inclinometry-based applications, photo capture applications, or motion capture systems. This study aimed to assess the validity, intra-rater, and inter-rater reliability of the VeloFlex system (VS), which is a new camera-based tool designed for tracking joint trajectories and measuring joint ROM. Materials and Methods: Thirty-five healthy volunteers (16 females
Relationship between resolution and accuracy of four intraoral scanners in complete-arch impressions
2018
Background The scanner does not measure the dental surface continually. Instead, it generates a point cloud, and these points are then joined to form the scanned object. This approximation will depend on the number of points generated (resolution), which can lead to low accuracy (trueness and precision) when fewer points are obtained. The purpose of this study is to determine the resolution of four intraoral digital imaging systems and to demonstrate the relationship between accuracy and resolution of the intraoral scanner in impressions of a complete dental arch. Material and methods A master cast of the complete maxillary arch was prepared with different dental preparations. Using four di…
Denoising AVIRIS-NG Data for Generation of New Chlorophyll Indices
2021
The availability of Airborne Visible and Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) data has enormous possibilities for quantification of Leaf Chlorophyll Content (LCC). The present study used the AVIRIS-NG campaign site of Western India for generation and validation of new chlorophyll indices by denoising the AVIRIS-NG data. For validation, concurrent to AVIRIS-NG flight overpass, field samplings were performed. The acquired AVIRIS-NG was subjected to Spectral Angle Mapper (SAM) classifier for discriminating the crop types. Three smoothing techniques i.e., Fast-Fourier Transform (FFT), Mean and Savitzky-Golay filters were evaluated for their denoising capability. Raw and fil…
Wine label design as a strategic tool to attract consumers. A marketing study on Sicilian wine positioning
2013
Negli ultimi anni il packaging e stato considerato dalle aziende vinicole uno tra i piu importanti strumenti del marketing. Infatti, grazie all’utilizzazione di immagini e testi, e possibile comunicare chiaramente al mercato messaggi coerenti con i prodotti, con i valori dell’azienda e con i target di consumatori di riferimento. In questo studio si e voluto conoscere quanto le etichette siano importanti per le cantine siciliane nelle scelte di posizionamento dei loro vini. Si e voluta, inoltre, misurare l’influenza che le etichette esercitano sui consumatori, indirizzando ed orientando le preferenze al momento dell’acquisto di un vino, senza tralasciare l’eventuale effetto attrattivo causat…
Reliability and validity of the form 90 interview.
2004
<i>Objective:</i> Alcohol consumption is a central variable in substance abuse research and treatment. The study reports the psychometric characteristics of the German version of the Form 90 interview for the assessment of recent alcohol consumption. <i>Method:</i> Reliability was evaluated in a test-retest study (7 days) with 30 consecutively admitted psychiatric inpatients with alcohol dependence. Validity of Form 90 was assessed with a second sample of 60 alcohol-dependent inpatients. <i>Results:</i> Form 90 demonstrated good to excellent retest reliability for the central variables of alcohol consumption. Retest reliability Pearson correlation coeffic…
Comparison between adenosine triphosphate bioluminescence and aerobic colony count to assess surface sanitation in the hospital environment
2022
Background: Adenosine triphosphate bioluminescence produced by the firefly luciferase has been successfullyintroduced to verify cleaning procedures in the food industry according to the Hazard Analysis Critical Control Pointprogram.Our aim was to evaluate the reliability of bioluminescence as a tool to monitor the effectiveness of sanitation in healthcaresettings, in comparison with the microbiological gold standard.Methods: 614 surfaces of various material were randomly sampled in Policlinico University Hospital units in Palermo,Italy, to detect adenosine triphosphate bioluminescence and aerobic colony count. Linear regression model andPearson correlation coefficient were used to estimate …
Benefit of using an age-adjusted D-dimer cut-off
2015
Introduction: The association between a low-moderate pretest clinical probability and a negative D-dimer (DD) value is able to exclude the possibility of pulmonary embolism (PE). The value of DD seems to increase with age, reducing its specificity. Therefore, we intend to evaluate the usefulness of an age-adjusted cut-off value for age above 50 years, applying the formula suggested by Douma (age*10) set to our laboratory method (age*5) (1) . Patients and Methods: Observational, retrospective study from January to December 2011. DD test were performed to 1515 patients attended in the emergency room of our hospital according to the clinical suspicion made by the doctor who evaluated them. The…
Validity and Reliability of a New Optoelectronic System for Measuring Active Range of Motion of Upper Limb Joints in Asymptomatic and Symptomatic Sub…
2019
The aim of this study was to evaluate the validity of the Veloflex infrared dynamic angle-meter (Veloflex-IDA) and the intra- and inter-rater reliability when measuring the ranges of motion (ROMs) of the upper limb joints. Thirty-five healthy and 20 symptomatic participants were evaluated. Twelve upper limb movements were measured in two sessions with the Veloflex-IDA, which is a device composed of a camera that tracks the trajectory of retro-reflective markers. In addition, a goniometer was used in the first session to evaluate concurrent validity. Validity and agreement were evaluated by Pearson correlation coefficient (r) and Bland&ndash
