INDOVINA CHI VIENE A CENA? QUESTIONI PSICO-SOCIO-GIURIDICHE NEL CICLO DI VITA DELLA COPPIA MISTA
2013
La famiglia, gruppo sociale con storia e che crea storia (Scabini, 1985), è stata negli anni protagonista di numerose trasformazioni nella sua struttura e nelle sue funzioni. Tra le nuove forme familiari oggetto di ricerca in campo psico-sociale vi è le coppia mista determinata anchʾessa da fenomeni demografici ed economici che, a loro volta, hanno richiesto adattamenti sociali e interventi legislativi ad hoc. Lʾanalisi delle caratteristiche della coppia mista consente di esplorare la praticabilità dellʾintegrazione di differenti esperienze culturali a livello di rapporto di coppia, familiare e sociale (Scabini, Regalia e Giuliani, 2007), esprimendo il livello più profondo dʾincontro tra cu…
Composition of mosses, their metabolites and environmental stress impacts
2018
Sūnas ir nozīmīga augu grupa ar plašu izplatību. Sūnu sastāva pētījumi ir kļuvuši aktuāli, ņemot vērā bioloģiski aktīvu savienojumu klātbūtni un augsto izturību pret vides apstākļu mainību. Promocijas darba mērķis ir analizēt sūnu sastāvu, to metabolītus un vides stresa ietekmes uz tiem. Veikta sūnu sekundāro metabolītu ekstrakcijas apstākļu izpēte, kas nodrošina liela skaita vielu identifikāciju. Sūnu lipīdi satur daudzas bioloģiski aktīvas vielas un veikta to aktivitātes izpēte. Sūnu sekundārie metabolīti uzrāda augstu antimikrobiālo aktivitāti un spējas inhibēt vairāku vēža šūnu līniju attīstību un līdz ar to satur perspektīvas vielu grupas izmantošanai biomedicīnā. Vides stresa ietekmes…
A comparative analysis of the sustainability of rice cultivation technologies using the analytic network process
2010
Sustainability of local farming systems and technologies is a very important issue that faces notorious measurement difficulties. Multi-criteria methods may help researchers to solve empirical problems in the construction of composite sustainability indicators and in ranking agricultural technologies according to their sustainability. This paper shows how a multi-criteria decision-making technique, the Analytic Network Process (ANP), can be fruitfully employed to this end. Contrary to simpler and hierarchical goal-criteria-alternative approaches, in ANP all the elements in the network can be related in any possible way, which means that a network can incorporate feedback and interdependent …
Experimental Procedures of Accelerated Aging and Evaluation of Effectiveness of Nanostructured Products for the Protection of Volterra (Italy) Panchi…
2022
The aims of the research were to evaluate the effectiveness of the application of nanostructured products on Volterra calcarenite stone and to define the experimental conditions and procedures of accelerated aging tests, able to simulate different degradation on the studied lithotype. The work focused on methods of performing accelerated aging tests in order to simulate different effects of environmental decay involving stone used on a historical site. The rock samples were examined before and after three treatment types: cyclic salt spray chamber, cycles of freezing–thawing and cycles of thermal shock. After each artificial aging cycle, changes in appearance were noted and chemical and phy…
Analysis of the possibility of using stainless steel and copper boride alloy as catalyst for microbial fuel cell fuel electrode= Analiza możliwości z…

wytwarzania energii elektrycznej z substancji odpadowych, jak i technologii oczyszczania ścieków. Ogniwa te charakteryzują się niskimi kosztami inwestycyjnymi. Ze względu na znakomite własności katalityczne, w wysokowydajnych ogniwach paliwowych (np. wodorowo-tlenowych), jako katalizator stosowana jest platyna. Jednak koszt platyny praktycznie uniemożliwia stosowanie jej w MFC. Z tego względu należy poszukiwać innych katalizatorów nie zawierających metali szlachetnych. W mikrobiologicznych ogniwach paliwowych najczęściej stosuje się elektrody grafitowe. Praca przedstawia analizę możliwości wykorzystania stali nierdzewnej oraz stopu Cu-B jako katalizatora elektrody paliwowej w mikrobiologicz…
Clinical justification of dental radiology in adult patients: A review of the literature
2007
Although the radiological doses used by dentists are low individually, patients are often exposured to many repeat dental radiographic examinations. The ‘routine’ use of dental radiography, such as screening of all patients using dental panoramic radiography (DPRs) or a random decision to take a dental radiograph, will inevitable lead to unnecessary patient exposure. The use of Radiographic Referral Criteria has now become a legal requirement for all practitioners following the adoption of European Legislation. All exposures to x-rays should be clinically justified and each exposure should be expected to give the patient a positive net benefit. Recently the European Commission has published…
Vecchie e nuove minoranze: definizioni e strumenti di tutela
2018
This papers studies different issues related to minorities rights. After trying to define what should be intended as minorities in contemporary West societies and exploring if it is possible to make a difference between old and new minorities, the research focuses on the main issues that are at stake. In particular, the paper aims at discovering which are the rights involved and how such rights can be categorised, as human, cultural, individual or community rights. The research will show how new minorities are in need of having their own identities recognised and protected by our West societies. This requires the achievement of a real process of integration to be carried out through two com…
LH administration as a potential strategy for ovarian protection and female fertility preservation against highly gonadotoxic chemotherapy
2022
Els ovaris contenen una reserva de fol·licles no renovable, que produeixen un únic ovòcit fecundable a cada cicle menstrual al llarg de l'etapa reproductiva femenina (15-49 anys), però que disminueix progressivament amb l'edat. Per tant, els factors que afecten negativament la dotació de fol·licles provocaran una reducció significativa de la vida reproductiva en la dona. Les teràpies oncològiques basades en l'administració de quimioteràpia alquilant s'utilitzen habitualment per a tractar els càncers ginecològics en pacients joves, però amb freqüència acceleren l'esgotament de la reserva fol·licular i l'aparició de la menopausa. Els efectes secundaris de la quimioteràpia sobre la fertilitat,…
UV filters: From sunscreens to human body and the environment
2007
Recognition of the harmful effects of ultraviolet (UV) radiation on the skin has triggered development of organic chemicals (commonly referred as UV filters) that can absorb UV radiation and attenuate the negative effects of sunlight exposure. Depending on the properties and the intended degree of protection, a wide array of combinations is being marketed as delivering protection against most kinds of UV-induced skin damage. However, some UV filters have dermatological implications, so maximum applicable concentrations have been established. To monitor to what extent commercial products comply with the mandatory limits, several analytical methods have been used for their determination in co…
Achieving agreement on service needs in child protection : Comparing children’s, mothers’ and practitioners’ views over time and between approaches
2022
Purpose While studies on service users’ participation and their perceptions on the quality of services exist, agreement between family members’ and practitioners’ assessments of the family’s situation has received less interest. The purpose of this paper is to investigate agreement and its effect on outcomes by comparing the viewpoints of three groups of informants (children, mothers and practitioners) in the context of statutory child protection in two study groups – one applying a systemic approach (SPM) and a service-as-usual control group (SAU). Design/methodology/approach A quasi-experimental repeated-measures study design was applied. Outcome data comprised 112 cases (SPM cases n = 5…
