Applying an operating model for the environmental risk assessment in Italian Sites of Community Importance (SCI) of the European Commission Habitats …
2013
The fast development of agro-biotechnologies asks for a harmonized approach in risk analysis of GMO's releases, where "risk analysis" entails the assessment, management and communication of risk. Risk assessment consists in the evaluation of the likelihood that a hazard occurs, associated with the presence of the receptor(s) in the receiving environment, and the determination of their potential degree of exposure to the hazard. The whole process has to be both science based and applied case by case, and it involves a very complicated procedure that needs to be transformed in an operational and standardized tool. Beginning in 2003, an expert group on behalf of the Italian Ministry of the Env…
Odonats del País Valencià: diversitat, factors implicats en la composició de les seues comunitats i respostes als senyals de risc durant la fase d'ou
2017
Libèl·lules i espiadimonis són els noms comuns emprats per a anomenar eixos insectes que tan familiars en resulten i que configuren l’ordre escollit per a la realització d’aquesta tesi doctoral: el dels odonats. D’entre les característiques taxonòmiques que el configuren com a grup, cal destacar dos trets diagnòstics: un de la fase adulta i l’altre de la fase larvària. Un és l’òrgan copulador dels mascles adults, el qual s’ubica en el segon segment abdominal; aquesta característica determina un comportament reproductor exclusiu: durant l’aparellament el mascle doblega l’abdomen per a poder arribar a l’orifici genital de la femella. L’altre tret és la modificació del llavi inferior de les la…
Sustainable urban transport policy in emerging countries – case study of Mexico
2015
Negatywne efekty zewnętrzne transportu stanowią bolączkę współczesnych miast, niekorzystnie oddziałując na procesy rozwoju społeczno-gospodarczego. Problemy te są widoczne nie tylko w krajach wysoko czy średnio rozwiniętych – w ogromnym stopniu borykają się z nimi wielomilionowe i wielkopowierzchniowe metropolie, które z kolei są charakterystyczne głównie dla krajów wschodzących, jak np. Chiny, Indie, Brazylia czy Meksyk. Celem artykułu jest przedstawienie wybranych aspektów polityki zrównoważonego rozwoju transportu w stolicy jednego z tych krajów – Meksyku. Autorka starała się również odpowiedzieć na pytanie, w jaki sposób specyficzne uwarunkowania lokalne o różnym charakterze determinują…
The acute effects of different high-intensity conditioning activities on sprint performance differ between sprinters of different strength and power …
2021
The purpose of the present study was to examine the effect of different conditioning activities (CAs) on short-term increase in sprint performance. In twelve male sprinters (21.1+2.6 years, 100 m performance: 11.5+0.6 s) their body composition, half squat maximum strength, 100 m sprinting and countermovement jump performances were evaluated. The performance of a 50 m sprint (splits at 10 m, 30 m and 50 m) was evaluated before and 5, 10 and 15 min after four postactivation performance enhancement CAs on different occasions: [1] 3 sets x 4 s maximum isometric half squat (IHF), [2] 3 sets x 3 consecutive countermovement jumps (cCMJs), [3] 3 repetitions x 30 m overspeed sprinting (OVSP) and [4]…
Heavy-Ion-Induced Degradation in SiC Schottky Diodes : Incident Angle and Energy Deposition Dependence
2017
Heavy-ion-induced degradation in the reverse leakage current of SiC Schottky power diodes exhibits a strong dependence on the ion angle of incidence. This effect is studied experimentally for several different bias voltages applied during heavy-ion exposure. In addition, TCAD simulations are used to give insight on the physical mechanisms involved. peerReviewed
Prenatal exposure to diazepam and alprazolam, but not to zolpidem, affects behavioural stress reactivity in handling-naïve and handling-habituated ad…
2002
A gentle long-lasting handling produces persistent neurochemical and behavioural changes and attenuates the impairment in the behavioural reactivity to novelty induced by the prenatal exposure to diazepam (DZ) in adult male rat progeny. This study investigated the consequences of a late prenatal treatment with three GABA/BDZ R agonists (DZ) alprazolam (ALP) and zolpidem (ZOLP)), on different stress-related behavioural patterns, in non-handled (NH), short-lasting handled (SLH) and long-lasting handled (LLH) adult male rats exposed to forced swim test (FST), acoustic startle reflex (ASR) and Vogel test (VT). The effects on motor activity were evaluated in the open field and in the Skinner box…
Diabēta medikamentu blakusparādības
2016
Ievads: Vēljoprojām ir sastopamas nozīmīgas blaknes diabēta zālēm, kas ir īpaši nozīmīgi pieaugot saslimstībai ar diabētu pasualē, kā arī Latvijā. Atpazīt diabēta medikamentu izraisītās blaknes ir svarīgi, lai novērstu smagās komplikācijas, ko tās var radīt. Pētijuma mērķis: pētījuma mērķis bija konstatēt blakņu esamību hospitalizētajiem diabēta pacientiem. Materiāli un Metodes: pētījumi, iekļāva pacientus, kuri diagnozticēti ar diabetes mellitus. Pacienti tika iztaujāti par medikamentiem, kurus viņi lieto atveseļošanās periodā un par viņu zināmām vai nezināmajām novērotajām blaknēm. Rezultāti: Pētījumā tika iekļauti 50 pacienti, ar abu, 1. un 2. tipa diabētiem. Pētāmo pacientu grupa sastāv…
Economic Sustainability of Italian Greenhouse Cherry Tomato
2014
Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, b…
Dissemination/Communication Plan. Period concerning the plan: 01.01.2018-31.12.2020.
2018
The plan concerning different dissemination/communication activities during three years of the project implementation is given. Scientific results are proposed to be disseminated in well-recognized bi-annual international conferences, such as European Conference on Composite Materials (ECCM) and International Conference on Composite Materials (ICCM). Self-archiving of the main project results is planned within subject-based open-access repositories, such as ResearchGate and Zenodo. Two scientific publications in Q1-Q2 SCI journals and two popular scientific publications in popular scientific Latvian journals are foreseen. All data files obtained within the project are to be stored in centra…
Single Event Upsets Induced by Direct Ionization from Low-Energy Protons in Floating Gate Cells
2017
Floating gate cells in advanced NAND Flash memories, with single-level and multi-level cell architecture, were exposed to low-energy proton beams. The first experimental evidence of single event upsets by proton direct ionization in floating gate cells is reported. The dependence of the error rate versus proton energy is analyzed in a wide energy range. Proton direct ionization events are studied and energy loss in the overlayers is discussed. The threshold LET for floating gate errors in multi-level and single-level cell devices is modeled and technology scaling trends are analyzed, also discussing the impact of the particle track size. peerReviewed
