Incorporation of zeolitic imidazolate framework (ZIF-8)-derived nanoporous carbons in methacrylate polymeric monoliths for capillary electrochromatog…
2017
A series of metal organic frameworks-derived nanoporous carbons originating from zeolitic imidazolate framework-8 (ZIF-8) crystals as precursors have been prepared via varying the preparation conditions. The ZIF-8-derived carbons were subsequently admixed in the methacrylate monomers containing polymerization mixtures and polymerized to obtain monolithic columns for capillary electrochromatography (CEC). The effect of particle size and content of the ZIF-8-derived carbon materials in the polymerization mixture on the performance of the hybrid monolithic columns was investigated in detail. The resulting composites were characterized using scanning electron microscopy. Using short time UV-ini…
Turmoil at Turrialba Volcano (Costa Rica): Degassing and eruptive processes inferred from high-frequency gas monitoring
2016
Eruptive activity at Turrialba Volcano (Costa Rica) has escalated significantly since 2014, causing airport and school closures in the capital city of San Jose. Whether or not new magma is involved in the current unrest seems probable but remains a matter of debate as ash deposits are dominated by hydrothermal material. Here we use high-frequency gas monitoring to track the behavior of the volcano between 2014 and 2015 and to decipher magmatic versus hydrothermal contributions to the eruptions. Pulses of deeply derived CO2-rich gas (CO2/S-total>4.5) precede explosive activity, providing a clear precursor to eruptive periods that occurs up to 2weeks before eruptions, which are accompanied by…
Listado taxonómico comentado de los Capitélidos (Annelida, Polychaeta) de la península Iberica, islas Chafarinas, Baleares y Canarias
2013
[EN] The present annotated checklist has been elaborated after revision of preserved materials (from the Museo Nacional de Ciencias Naturales, Madrid and the reference collection of the Marine Biology Laboratory of the University of Valencia) and published literature related to capitellids from the Iberian Peninsula, Chafarinas, Balearic and Canary Islands. Twenty-four species and subspecies belonging to thirteen genera are recognized as valid taxa. With this checklist we include some taxonomic details and information on distribution at both global and regional levels. This work includes the setal formula and diagrammatic representation of capitellid taxa treated in this study.
Environment in Megacities: Tehran Waterscapes
2021
Defining contemporary urban paradigms is the challenge of this time, especially when the urban dynamics are so fluid they spread uncontrollably in overextended and overpopulated territories. This is the case for megacities, metropolitan areas with more than 10 million inhabitants, which place the emphasis on how to manage energy consumption in such filled places. In this frame, the city of Tehran, the capital of the Islamic Republic of Iran, scene of political and cultural disputes, administrative and economic headquarter of the country, with its nearly 15 million residents and a daily traffic of more than 20 million people, is currently one of the most populous cities in the world and repr…
Contrasting styles of deep-marine pyroclastic eruptions revealed from Axial Seamount push core records
2015
Abstract A comprehensive understanding of explosive basaltic eruption processes in the deep-sea relies upon detailed analysis and comparison of the variety of volcaniclastic lithologies on the seafloor, which has been challenged by insufficient sample recovery. A dedicated ROV-based sampling approach using long push cores offers an unparalleled opportunity to fully characterize the diversity of unconsolidated volcaniclastic lithofacies on a recently active seamount. Lithofacies from Axial Seamount record two styles of pyroclastic eruptions, strombolian and phreatomagmatic, at 1.5 km water depth. Strombolian eruptions are represented by abundant fluidal and highly vesicular (up to 50%) vitri…
Ginekoloģisko pacientu sagatavošana distances staru terapijā
2020
Bakalaura darbs: “Ginekoloģisko pacientu sagatavošana distances staru terapijā” sastāv no ievada, teorētiskās un pētījuma daļas, secinājumiem. Tēmas aktualitāte pamatota ar sagatavošanās nepieciešamību ginekoloģiskajiem pacientiem, lai nodrošinātu kvalitatīvu distances staru terapiju. Teorētiskajā daļā ir analizēta un apkopota literatūra par iegurņa orgāniem, anatomiju, pataloģijām, dinamiku, pildījumu un gatavošanās metodēm. Bakalaura darba pētnieciskajā daļā izvērtēti un analizēti 50 ginekoloģisko pacientu datortomogrāfijas attēlu dati katrai 6. frakcijai. Darba mērķis: izvērtēt pacientu iegurņa orgānu dinamiku distances staru terapijā ginekoloģijas pacientiem. Darba apjoms: 4 nodaļas, 13…

Latvijas inflācijas jutīgums pret globālā faktiskā un potenciālā izlaides apjoma starpības izmaiņām
2018
Maģistra darbā veikta inflācijas jutīguma pārbaude pret sagaidāmo inflāciju, iekšzemes un globālā izlaides apjoma starpībām un importa cenu izmaiņām. Globālā izlaides apjoma starpības aprēķinam izmantotas trīs svēršanas metodes – importa un eksporta, importa, IKP svēršanas metodes. Globālā izlaides apjoma aprēķinam tiek izmantoti IKP dati par 9 nozīmīgākajām Latvijas ārējās tirdzniecības partnervalstīm. Potenciālā izlaides apjoma novērtēšanai tiek izmantots Hodrika-Preskota filtrs. Pētījumā izmantots papildinātais Filipa līknes modelis ar un bez novēlojumiem, iekļaujot sagaidāmo inflāciju, Latvijas un globālā izlaides apjoma starpības, kā arī importa cenu izmaiņas, kā arī tiek veikta modeļa…
Smart City. Una strategia per ri-pensare lo sviluppo urbano sostenibile
La ricerca prende avvio dalle riflessioni sulla crescita della città contemporanea, alla luce del sempre più allarmante sfruttamento delle risorse della natura, criticità che contribuisce al riscaldamento globale. Interrogarsi sulla Smart City è stato un importante punto di riflessione in una fase storica in cui il tema della città intelligente rappresenta una strategia per ri-pensare lo sviluppo urbano sostenibile, partendo da una visione che metta a fattor comune progetti politici, ambientali, economici, sociali e culturali, è fondamentale che le Istituzioni siano messe in grado di attivare processi di medio e lungo periodo e di breve termine che creino le basi fondanti per l’evoluzione e…
