Constant sign and nodal solutions for parametric anisotropic $(p, 2)$-equations
2021
We consider an anisotropic ▫$(p, 2)$▫-equation, with a parametric and superlinear reaction term.Weshow that for all small values of the parameter the problem has at least five nontrivial smooth solutions, four with constant sign and the fifth nodal (sign-changing). The proofs use tools from critical point theory, truncation and comparison techniques, and critical groups. Spletna objava: 9. 9. 2021. Abstract. Bibliografija: str. 1076.
Lidar detection of carbon dioxide in volcanic plumes
2015
Volcanic gases give information on magmatic processes. In particular, anomalous releases of carbon dioxide precede volcanic eruptions. Up to now, this gas has been measured in volcanic plumes with conventional measurements that imply the severe risks of local sampling and can last many hours. For these reasons and for the great advantages of laser sensing, the thorough development of volcanic lidar has been undertaken at the Diagnostics and Metrology Laboratory (UTAPRAD-DIM) of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA). In fact, lidar profiling allows one to scan remotely volcanic plumes in a fast and continuous way, and with high s…
La mesure de l'efficacité scolaire par la méthode de l'enveloppe : test des filières alternatives de recrutement des enseignants dans le cadre du pro…

Data envelopment and school effectiveness: contract teachers' efficiency compared to civil servants in the Education for all process) In the context of EFA process, countries, in general the most depressed LDC, both constrained by scarcity of funding and urgency for expanding school access have set up new tracks for teacher recruitment on annually renewable contracts. Those teachers are often not professionally trained in regards with traditional pedagogical curricula. They receive much lower salaries than regular civil service teachers. This has been a controversial policy, but there is very limited evidence on the effectiveness or failure of contract teachers in improving student learning…
Uztura paradumu, fiziskās aktivitātes un fizisko veselību raksturojošo parametru izvērtējums 5-7 gadus veciem bērniem
2021
Pirmsskolas vecumā tiek likts pamats personīgai veselībai un fiziskām īpašībām, kas nepieciešamas efektīvai līdzdalībai nākotnē dažādās dzīves jomās. Daudzu pētījumu dati rāda, ka bērnībā veidotie uztura un fizisko aktivitāšu paradumi, kas saglabājas turpmākos dzīves gados, ir veselīga dzīvesveida stūrakmens pieaugušā vecumā. Tomēr, ja bērnam jau agrīnā vecumā ir vērojama paaugstināta tauku masa vai aptaukošanās, tad saglabājas augsts risks, ka tā tāda būs arī pieaugušā vecumā, kā rezultātā var veidoties vairāku, tai skaitā, kardiometabolo saslimšanu risks. Antropometriska ķermeņa fiziskā statusa novērtēšana ir vienkāršs veids, kā veikt fiziskā statusa novērtējumu gan plašā populācijā, gan …
