Stress gradient versus strain gradient constitutive models within elasticity
2014
Abstract A stress gradient elasticity theory is developed which is based on the Eringen method to address nonlocal elasticity by means of differential equations. By suitable thermodynamics arguments (involving the free enthalpy instead of the free internal energy), the restrictions on the related constitutive equations are determined, which include the well-known Eringen stress gradient constitutive equations, as well as the associated (so far uncertain) boundary conditions. The proposed theory exhibits complementary characters with respect to the analogous strain gradient elasticity theory. The associated boundary-value problem is shown to admit a unique solution characterized by a Helling…
Norm-inflation results for purely BBM-type Boussinesq systems
2022
This article is concerned with the norm-inflation phenomena associated with a periodic initial-value abcd-Benjamin-Bona-Mahony type Boussinesq system. We show that the initial-value problem is ill-posed in the periodic Sobolev spaces H−sp (0, 2π)×H−sp (0, 2π) for all s > 0. Our proof is constructive, in the sense that we provide smooth initial data that generates solutions arbitrarily large in H−sp (0, 2π) × H−sp (0, 2π)-norm for arbitrarily short time. This result is sharp since in [15] the well-posedness is proved to holding for all positive periodic Sobolev indexes of the form Hsp (0, 2π) × Hsp (0, 2π), including s = 0. peerReviewed
Bridging the gap between research and practice : using phenomenographic findings to develop training for career practitioners
2021
AbstractThis study contends that phenomenography offers both a useful research method and practical tools for developing education and training for career practitioners. After introducing the basic principles of phenomenography, the study reviews previous research on its potential in developing pedagogical practices. It explores how the phenomenographic findings were utilized to design an online skills training programme for career practitioners. The study finds that phenomenographic research serves three practical pedagogical purposes: (1) revealing how learners understand certain concepts or phenomena, (2) elucidating how these understandings differ; and (3) identifying critical aspects i…
Combination of ozonation and photocatalysis for purification of aqueous effluents containing formic acid as probe pollutant and bromide ion
2014
The treatment by advanced oxidation processes (AOPs) of waters contaminated by organic pollutants and containing also innocuous bromide ions may generate bromate ions as a co-product. In the present work heterogeneous photocatalysis and ozonation have individually been applied and in combination (integrated process) to degrade the organic compounds in water containing also bromide anions. The results show that: i) the sole photocatalysis does not produce bromate ions and in the case of its presence, it is able to reduce bromate to innocuous bromide ions; ii) the integration of photocatalysis and ozonation synergistically enhances the oxidation capabilities; and iii) in the integrated proces…
New land valuation criteria after the Spanish 2011 Valuation of Land Regulation : the objectivation of building expectations in rural land
2013
The land valuation regime has undergone one of its most important modifications at the hands of the 2008 Land Act and its 2011 Regulation. According to the so-called objectivity principle - which defines all established methods for the new basic situations of land - and according to the stated prohibition of taking into consideration building expectations arising from granted planning permission, the fact is that the existence of circumstances that are not a natural consequence of landowner investments made on the property is easily deducible. This is inconsistent with the spirit of the Land Act in force contained in its Explanatory Memorandum.
Bāriņtiesas kā institūcijas loma bērnu tiesību aizsardzībā
2016
Bakalaura darbu “Bāriņtiesa kā institūcijas loma bērnu tiesību aizsardzībā” izstrādāja Jana Horste zinātniskās vadītājas prof. Jautrītes Briedes vadībā. Bakalaura darba izstrādes rezultātā, autores skatījumā, sasniegts izvirzītais mērķis, kur tika izvērtēts bāriņtiesas darbs bērnu tiesību aizsardzības nodrošināšanā. Darbs ir izstrādāts četrās nodaļās: pirmajā nodaļā tiek apskatīta bāriņtiesu izvedošana un tās darbības principi. Otrjā nodaļā tiek apskatīta bāriņtiesas kompetence bērnu tiesību aizsardzībā, bāriņtiesas tiesības un pienākumi, kā arī bāriņtiesas faktiskā rīcība bērnu interešu nodrošināšanā. Trešajā nodaļā tiek apskatīta lēmumu pieņemšana bāriņtiesā - gan koleģiālu, gan vienperso…
Bērna labāko interešu principa saturs
2016
Bērna labāko interešu princips ir viens no svarīgākajiem starptautiski atzītajiem instrumentiem bērnu tiesību īstenošanā un attīstīšanā. Bērns kā tiesību subjekts ir ierobežots savu tiesību autonomā realizācijā, kā dēļ tas ir atkarīgs no citu personu motivācijas izvērtēt tā tiesības objektīvi. Šī iemesla dēļ, bērna labāko interešu principa klātbūtne ikvienā jautājumā, kas skar bērnu, ir izšķiroša. Bakalaura darbā “Bērna labāko interešu principa saturs” tiek atklāta bērna labāko interešu principa nozīme bērnu tiesību realizēšanā, tā ietekmes spēks un tvērums. Darbā tiek konstatēti arī galvenie problēmjautājumi pricipa praktiskajā piemērošanā un no tā izrietošās sekas. Bakalaura darbā tiek ap…
Shaping of a ground state rotational wavepacket by frequency-chirped pulses
2001
0953-4075; A coherent rotational superposition state is produced in the ground vibronic level of N2 through the interaction of the molecule with the electric field vector of a nonresonant laser pulse. This rotational wavepacket is shaped with a linear frequency chirp of the laser field. The structural shape of the rotational coherences shows a strong dependence with the frequency-chirp amplitude. A comparison with a theoretical model allows the interpretation of the observed effects in terms of dephasing of the wavepacket induced by the laser phase distortion. Application of the presented results to the phase characterization of short XUV pulses is suggested.

Cannabis e terapia del dolore. Un singolare caso di limitazione del diritto alla cura.
2020
L’articolo descrive l’assetto del mercato della cannabis terapeutica definito dalla legislazione italiana, evidenziandone la dubbia compatibilità con l’ordinario paradigma accolto dalla Corte di Giustizia in materia di diritto della concorrenza. Gli elementi specializzanti alla base di tale devianza possono essere individuati nelle esigenze di tutela della salute pubblica, dell’ordine pubblico e della pubblica sicurezza: questa peculiarità (presupposta dalla normativa italiana e dalla sua matrice internazionale) non consente comunque di giudicare la regolazione della cannabis terapeutica conforme all’interpretazione consolidata degli articoli 49, 52, 56T.f.Ue e alla altrettanto stabile giur…
