ANALYTICAL PROCEDURES FOR THE DETERMINATION OF TRACE AMOUNTS OF XENOBIOTICS IN ENVIRONMENTAL WATER SAMPLES
2016
Wciąż wzrastające zanieczyszczenie środowiska związane z działalnością człowieka stanowi poważny problem ekologiczny współczesnego świata. Ksenobiotyki to substancje obce i potencjalnie szkodliwe dla organizmów żywych. Obecność niektórych z nich w środowisku wodnym może nieść za sobą poważne konsekwencje. Do najbardziej niebezpiecznych należą antybiotyki oraz pestycydy. Rozwój nauki i techniki umożliwił kontrolowanie tych substancji w środowisku naturalnym. Oznaczanie śladowych ilości ksenobiotyków w próbkach wód środowiskowych jest złożonym procesem, wymagającym zastosowania odpowiedniej metody ekstrakcyjnej i analitycznej. Złożoność matrycy oraz obecność substancji współobecnych stanowi d…
Käyttäjien ja kehittäjien välinen viestintä tietojärjestelmien kehittämisessä : haasteita ja ratkaisuja
2017
Tutkielman tavoitteena oli selvittää ja kerätä yhteen aiemmassa tutkimuksessa havaittuja haasteita käyttäjien ja kehittäjien välisessä viestinnässä tietojärjestelmäkehityksen kontekstissa, sekä näihin haasteisiin esitettyjä ratkaisuja. Tutkimus toteutettiin kirjallisuuskatsauksena. Tutkimustulokset luokiteltiin median samanaikaisuuden teorian ja käyttäjä-kehittäjäviestinnän käsitteistön pohjalta johdetun teoreettisen viitekehyksen mukaisesti. Tutkimustuloksista voidaan todeta, että suurimmat haasteet käyttäjien ja kehittäjien välisessä viestinnässä liittyvät yhteisymmärryksen luomiseen ja vaatimusmäärittelyyn, ja suurimpana yksittäisenä tekijänä haasteita aiheuttavat erilaiset yksilölliset …
Customer satisfaction within a large scale retail trading group: research design and control
2010
Even in contexts where Customer Management techniques are not very advanced, the need for relations with customers is as strong as to suggest expensive ad hoc researches able to simultaneously measure the satisfaction levels, to detect the eventual inadequacy of selling actions, to investigate the relations of customers with competitors. This is why the Grande Migliore Group in Palermo commissioned a research from the University of Palermo. The research was made in year 2008 at 10 Grande Migliore shops in Palermo and in other Western Sicily towns. The multipurpose nature of the research and the features of the customers population suggested the adoption of an ad hoc research design, the fea…
Prenatal Risk Calculation (PRC) 3.0: An Extended DoE-Based First-Trimester Screening Algorithm Allowing For Early Blood Sampling
2015
Aim: Both previous versions of the German PRC algorithm developed by our group for routine first-trimester screening relied on the assumption that maternal blood sampling and fetal ultrasonography are performed at the same visit of a pregnant women. In this paper we present an extension of our method allowing also for constellations where this synchronization is abandoned through preponing blood sampling to dates before 11 weeks of gestation. Methods: In contrast to the directly measured concentrations of the serum parameters PAPP-A and free ß-hCG, the logarithmically transformed values could be shown to admit the construction of reference bands covering the whole range from 16 to 84 mm CRL…
A reappraisal of the purported gastric pellet with Pterosaurian bones from the Upper Triassic of Italy
2015
A small accumulation of bones from the Norian (Upper Triassic) of the Seazza Brook Valley (Carnic Prealps, Northern Italy) was originally (1989) identified as a gastric pellet made of pterosaur skeletal elements. The specimen has been reported in literature as one of the very few cases of gastric ejecta containing pterosaur bones since then. However, the detailed analysis of the bones preserved in the pellet, their study by X-ray microCT, and the comparison with those of basal pterosaurs do not support a referral to the Pterosauria. Comparison with the osteology of a large sample of Middle-Late Triassic reptiles shows some affinity with the protorosaurians, mainly with Langobardisaurus pand…
Jurisdiction in cases of divorce, legal separation or marriage annulment
2021
The subject of coordination is fundamental for the functioning of jurisdictional rules of the Regulation n.2016/1103 on matrimonial property regimes and Regulation n.2016/1104 on the property consequences of registered partnerships. Both Property Regimes Regulations have the purpose of gathering litigation before the courts of one Member State and have the related procedures managed by the courts of the same Member State. Recital 34 of Regulation No. 2016/1103 specifies that matters of matrimonial property regime related to proceedings pending before the court of a member state hearing an application for divorce, legal separation or marriage annulment should be dealt with by the courts of t…

Liquid membranes as a sample preparation method in environmental analysis
2014
Because of the complexity of environmental matrices, there is a great need of application efficient sample preparation procedures for environmental analysis. One of such possibilities is using, during sample-pretreatment step, the membrane extraction (ME) methods. They include, for instance, a three-phase extraction system named supported liquid membranes that has been used in recent years many times for isolation and preconcentration of various analytes from complex sample matrices. The examples of application the commonly used types of SLMs, hollow fiber supported liquid membrane and flat sheet supported liquid membrane, are listed and described. Additionally, the area of membrane extract…
Disability, Health-Related Quality of Life and Mortality in Lumbar Spine Fusion Patients : A 5-Year Follow-Up and Comparison With a Population Sample
2022
Study Design: Prospective follow-up study. Objectives: We aimed to assess the effect of lumbar spine fusion (LSF) on disability, health-related quality of life and mortality in a 5-year follow-up, and to compare these results with the general population. Methods: 523 consecutive LSF operations were included in a prospective follow-up. Disability was assessed by the Oswestry Disability Index (ODI), and HRQoL by the 36-item Short Form (SF-36) questionnaire using the physical and mental summary scores (PCS and MCS). The patients were compared with an age-, sex-, and residential area matched general population cohort. Results: The preoperative ODI in the patients was 46 (SD 16), and the change …
Combining Sequence Analysis and Hidden Markov Models in the Analysis of Complex Life Sequence Data
2018
Life course data often consists of multiple parallel sequences, one for each life domain of interest. Multichannel sequence analysis has been used for computing pairwise dissimilarities and finding clusters in this type of multichannel (or multidimensional) sequence data. Describing and visualizing such data is, however, often challenging. We propose an approach for compressing, interpreting, and visualizing the information within multichannel sequences by finding (1) groups of similar trajectories and (2) similar phases within trajectories belonging to the same group. For these tasks we combine multichannel sequence analysis and hidden Markov modelling. We illustrate this approach with an …
