Grunts granulometriskā sastāva un fizikālo īpašību interpretācijas iespējas pēc statiskās zondēšanas datiem
2015
Rimšelis, M. „Grunts granulometriskā sastāva un fizikālo īpašību interpretācijas iespējas pēc statiskās zondēšanas datiem”. Bakalaura darbs. Rīga, Latvijas Universitāte, Ģeogrāfijas un Zemes zinātņu fakultāte, 2015. Bakalaura darba mērķis ir salīdzināt statiskās zondēšanas datus ar laboratorijā analizēto grunšu paraugu rezultātiem un novērtēt granulometriskā sastāva un fizikālo īpašību interpretācijas iespējas. Rezultāti pierāda, ka nav iespējams ar statisko zondēšanu noteikt tādus parametrus, kā grunts granulometriskais sastāvs un tādu fizikālu īpašību kā dabīgais mitrums, tomēr iegūtais berzes koeficients netieši norāda uz to mainību.
Īpašuma tiesību aprobežojumi īpaši aizsargajāmās dabas teritorijās.
2021
Maģistra darba tēma "Īpašuma tiesību aprobežojumi īpaši aizsargājamās dabas teritorijās". Latvijas valsts teritorijā ir liela dabas daudzveidība, kura sevī ietver īpaši aizsargājamas dabas teritorijas. Īpaši aizsargājamas dabas teritorijas noteiktas ar mērķi aizsargāt esošo dabas daudzveidību. Taču, aizsargājot dabas vērtības, tiek ierobežotas īpašuma tiesības personām, kuru īpašumi atrodas īpaši aizsargājamajās dabas teritorijās. Lai vienlaicīgi saglabātu personas tiesības uz īpašumu un dabas daudzveidību , ir noteikti kompensāciju mehānismi, kas atvieglo noteiktos īpašuma tiesību aprobežojumus. Nosakot īpašuma tiesību aprobežojumu apmēru īpaši aizsargājamās dabas teritorijās ,ir jāvērtē t…

The chemical composition of the aerial parts essential oil of Achillea cretica L. (Asteraceae) growing wild in Crete (Greece)
2022
Achillea cretica (L.) (Asteraceae) is a suffruticosa camefite plant, mainly distributed in Crete, Aegean Islands, and eastern Mediterranean area. In the present study, the chemical composition of the essential oil from aerial parts of a not previously investigated accession of Achillea cretica, collected in Crete, was analysed by GC-MS. The results showed the presence of large quantity of α-bisabolol (53.88%) followed by the related compound α-bisabolol-oxide (2.76%), and spathulenol (5.94%). Based on the composition of the essential oils of all the other Achillea taxa, several consideration have been carried out.
Characterization and antimicrobial activity of the volatile components of the flowers of Magydaris tomentosa (Desf.) DC. collected in Sicily and Alge…
2014
The essential oils of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) collected in Sicily (MSi) and Algeria (MAl), respectively, were obtained by hydrodistillation, and their compositions were analysed. The analyses allowed the identification and quantification of 23 components in MSi and 60 compounds in MAl, respectively, showing a very different profile in the composition of the two populations. The main components of MSi were cembrene (28.2%), α-springene (17.5%) and β-springene (14.8%), also present in MAl but in lesser amount (0.4%, 1.8% and 0.9%, respectively), whereas the principal constituents of MAl were (E)-nerolidol (35.4%), α-costol (13.3%) and β-costol (6.8%). Both MS…
High-precision measurement of a low Q value for allowed β−-decay of 131I related to neutrino mass determination
2022
The ground-state-to-ground-state β−-decay 131I (7/2+) → 131Xe (3/2+) Q value was determined with high precision utilizing the double Penning trap mass spectrometer JYFLTRAP at the IGISOL facility. The Q value of this β−-decay was found to be Q = 972.25(19) keV through a cyclotron frequency ratio measurement with a relative precision of 1.6 × 10−9. This was realized using the phase-imaging ion-cyclotron-resonance technique. The new Q value is more than 3 times more precise and 2.3σ higher (1.45 keV) than the value extracted from the Atomic Mass Evaluation 2020. Our measurement confirms that the β−-decay to the 9/2+ excited state at 971.22(13) keV in 131Xe is energetically allowed with a Q va…
Search for scalar leptoquarks in pp collisions at $\sqrt{s}$=13 TeV with the ATLAS experiment
2016
An inclusive search for a new-physics signature of lepton-jet resonances has been performed by the ATLAS experiment. Scalar leptoquarks, pair-produced in pp collisions at s √s = 13 TeV at the large hadron collider, have been considered. An integrated luminosity of 3.2 fb-1, corresponding to the full 2015 dataset was used. First (second) generation leptoquarks were sought in events with two electrons (muons) and two or more jets. The observed event yield in each channel is consistent with Standard Model background expectations. The observed (expected) lower limits on the leptoquark mass at 95% confidence level are 1100 and 1050 GeV (1160 and 1040 GeV) for first and second generation leptoqua…
Dynamics of a harmonic oscillator coupled with a Glauber amplifier
2020
A system of a quantum harmonic oscillator bi-linearly coupled with a Glauber amplifier is analysed considering a time-dependent Hamiltonian model. The Hilbert space of this system may be exactly subdivided into invariant finite dimensional subspaces. Resorting to the Jordan-Schwinger map, the dynamical problem within each invariant subspace may be traced back to an effective SU(2) Hamiltonian model expressed in terms of spin variables only. This circumstance allows to analytically solve the dynamical problem and thus to study the exact dynamics of the oscillator-amplifier system under specific time-dependent scenarios. Peculiar physical effects are brought to light by comparing the dynamics…
Bliski Wschód w ogniu. Salaficki dżihadyzm w ujeciu Patricka Cockburna
2015
Celem rozdziału jest omówienie obrazu salafickiego dżihadyzmu w Libii, Iraku i Syrii, który od lat analizuje Patrick Cockburn - komentator i reporter londyńskiego dziennika ,, The Independent". Cockburn, jak ujęła to Claire Fox (The Institute of Ideas), pisze w sposób błyskotliwy, pogłębiony i krytyczny. Autor, najpierw skupił się na przebiegu i skutkach upadku, rządzonej przez pułkownika Muammara Kadafiego, Arabskiej Libijskiej Dżamahiriji, o którym zdecydowały naloty Paktu Północnoatlantyckiego (NATO). W drugiej części tekstu zostały opisane sukcesy Islamskiego Państwa Iraku i Lewantu (Islamie State of Iraq and al-Sham, ISIS), fundamentalistycznych (salafickich) dżihadystów, którzy kontro…
