The Development and Precision of a Custom-Made Skitester

2021

In the sport of cross-country skiing, equipment has a direct influence on results. Ski teams do extensive testing of different ski base grinds and products on a yearly basis. To achieve reliable results, the quality of methods used for testing skis needs to be taken in to account in addition to factors including the physical characteristics of testing personnel and changes in weather conditions. The aim of this study was to introduce a custom-made skitester, that was developed for testing skis on real snow, in laboratory conditions, and to evaluate its precision. The current skitester is capable of glide testing both classic and skate skis as well as kick simulation for the testing of grip …

Single-event effects of space and atmospheric radiation on memory components

2017

Electronic memories are ubiquitous components in electronic systems: they are used to store data, and can be found in all manner of industrial, automotive, aerospace, telecommunication and entertainment systems. Memory technology has seen a constant evolution since the first practical dynamic Random- Access Memories (dynamic RAMs) were created in the late 60's. The demand for ever-increasing performance and capacity and decrease in power consumption was met thanks to a steady miniaturization of the component features: modern memory devices include elements barely a few tens of atomic layers thick and a few hundred of atomic layers wide. The side effect of this constant miniaturization was a…

Inappropriateness in laboratory medicine: an elephant in the room?

2017

Appropriateness of diagnostic testing can be conventionally described as prescription of the right test, using the right method, at the right time, to the right patient, with the right costs and for producing the right outcome. There is ongoing debate about the real burden of inappropriateness in laboratory diagnostics. The media coverage of this issue has also recently led to either over- or under-emphasizing the clinical, organizational and economic consequences. This is quite problematic, inasmuch as some reliable data are available in the current scientific literature, showing that inappropriateness of laboratory testing can be as high as 70%. This is especially evident for, though not …

Catching allergy by a simple questionnaire

2014

Background Identifying allergic rhinitis requires allergy testing, but the first-line referral for rhinitis are usually primary care physicians (PCP), who are not familiar with such tests. The availability of easy and simple tests to be used by PCP to suggest allergy should be very useful. Methods The Respiratory Allergy Prediction (RAP) test, based on 9 questions and previously validated by a panel of experts, was evaluated in this study. Results An overall number of 401 patients (48.6% males, age range 14–62 years) with respiratory symptoms was included. Of them, 89 (22.2%) showed negative results to SPT, while 312 (77.8%) had at least one positive result to SPT. Cohen’s kappa coefficient…

Survey of Italian Pediatricians on awareness, experiences and beliefs regarding direct-to-consumer genetic testing in minors

2022


 Background: Our study wanted to assess Italian pediatricians’ awareness, experience and beliefs regarding directto-consumer (DTC) genetic tests (GT) in minors, with a focus on those for predisposition to complex disease, lyfestyle, athletic ability and other inborn talents.
 Methods: A 28-item questionnaire was administered through the SurveyMonkey® web platform to the 9,086 members of the Italian Society of Pediatrics for which a valid email address was available. The survey was opened from April through November 2017. Statistical analyses were performed using the Graphpad software package.
 Results: 36.2% of the 442 respondents were aware of DTC-GT, but only 23.1% of them…

Trial profile: pilot study of the multicentre randomised trial of H. pylori eradication and pepsinogen testing for prevention of gastric cancer morta…

2019

Purpose: The GISTAR Pilot study is part of a large multi-centre randomised trial conducted in Latvia with the main aim to evaluate preventive strategies to decrease mortality from gastric cancer in high-risk areas, especially in the Baltic States and Eastern Europe. Participants: A total of 3,447 apparently healthy, asymptomatic participants (40-64 y/o) were recruited between 2013 and 2015 for the GISTAR pilot study. Participants were interviewed for socio-economic status, lifestyle, environmental and occupational exposures, medical history, family history of diseases, and dietary habits. Participants were randomly assigned to either Intervention (n=1,724) or Control (n=1,723) group. The in…

The Influence of Fatigue on Throwing and YBT-UQ Performance in Male Adolescent Handball Players

2020

Purpose: The goal of the present study was to assess the effects of fatigue on throwing and Upper Quarter Y Balance Test (YBT-UQ) performance in male adolescent handball players. We hypothesized that throwing and YBT-UQ performance will be decreased in response to an upper-body fatigue-protocol.Method: All male participants (N = 24, age: 14.8 ± 0.7 yrs) were handball players of a regional youth selection team. A radar gun was used for the assessment of throwing velocity. The YBT-UQ was executed assessing medial, inferolateral and superolateral reach directions normalized to the upper limb length together with a composite score. Immediately following a fatigue protocol of different sets of p…

A Quantitative Method for Localizing User Interface Problems: The D-TEO Method

2009

A large array of evaluation methods have been propo sed to identify Website usability problems. In log-based evaluation, inform ation about the performance of users is collected and stored into log files, and used to find problems and deficiencies in Web page designs. Most methods require the programming and modeling of large task models, which are cumbersome processes for evaluato rs. Also, because much statistical data is collected onto log files, recognizing which Web pages require deeper usability analysis is difficult. This paper suggests a novel quantitative method, called the D-TEO, for locating problematic Web pages. This semiautoma ted method explores the decomposition of interacti…

Uz autentisku materiālu balstītu audio kursa izstrāde un ieviešana skolēnu klausīšanās prasmju pilnveidei angļu valodā 11. klasē

2022

Praktiskās klausīšanās prasmju trūkums skolēnu vidū ir viena no biežāk novērojamām problēmām angļu valodas stundās. Dažādi testēšanas elementi tiek izmantoti ar mērķi novērtēt klausīšanas prasmes, tomēr patiesais klausīšanās izpratnes process netiek veidots. Skolēni nezina iemeslus, kāpēc, klausoties, viņi pieļāva īpašas kļūdas, un tas noved pie tā, ka viņiem nav iespēju izstrādāt savas stratēģijas, kā izvairīties no kļūdu pieļaušanas. Stundās nav pietiekami daudz iespēju iesaistīties aktīvā klausīšanās procesā un nav iespējams praktiski izmantot piezīmes, kas gūtas, klausoties, un darba autore to uzskata par vienu no faktoriem, kas skolēniem rada grūtības klausīties. Pētījuma mērķis bija i…
