Les traces de pas d'amphibiens, de dinosaures et autres reptiles du Mésozoïque français: inventaire et interprétations.
2007
Since the 19th century, thousands of footprints were observed in the geological series of the French Mesozoic. All are located in the Triassic and Jurassic. After a promising beginning, in France, it is only a few papers which will be published in the first half 20th century, unlike the USA and of others countries of Western Europe. One ought to wait about 1950 for a revival and now they are nearly 200 papers which were devoted to the ichnofossils. The literature abundance and the renewed interest of the naturalists for the palichnologic studies decided to us to write a synthesis work. This one begins with a stratigraphic inventory in which, localisation, age and paleontological contents of…
Straw as a contemporary biomaterial: energetic efficiency and enviromental sustanaibility
2016
Questo studio ha lo scopo di segnalare ricerche e applicazioni in ambito costruttivo europeo e non solo della paglia, con particolare attenzione all'efficienza energetica e al comfort abitativo. Il riciclo e riutilizzo dei materiali naturali sono gli obiettivi principali nella scelta di paglia come materiale da costruzione, consentendo di adottare un approccio metodologico complessivo, che potrebbe prendere in considerazione l'intero edificio del ciclo di vita. Partendo dalla storia dell'utilizzo di paglia nella costruzione edilizia, saranno riportati molti esempi di edifici che utilizzano tale materiale all'interno del loro involucro e struttura. Le caratteristiche principali della paglia …
Barības vielu atkarīgo signālceļu nozīme fenotipiskās atbildes veidošanā adenīna badināšanas laikā maizes rauga šūnās
2017
Šī darba ietvaros noskaidrota TOR un PKA raksturīgo mērķproteīnu - transkripcijas faktoru Gln3p, Msn2p, Msn4p un proteīnkināzes Rim15 iespējamā saistība ar auksotrofās adenīna badināšanas izraisītā paaugstinātā stresa izturības fenotipa veidošanos maizes raugā. Veikta izvēlēto mērķproteīnu sekvenču C-galu saīsināšana un pētīta izveidoto mutanto celmu subletālo stresu (oksidatīvā, karstuma un žāvēšanas) izturība, kā arī novērtēta NADPH/NADP un NADH/NAD attiecība. Secināts, ka visi pārbaudītie TOR un PKA mērķproteīni saistīti ar adenīna badināšanas izraisītajām atbildes reakcijām, apstiprinot barības vielu atkarīgo signālceļu asociāciju ar adenīna badināšanas izraisīto stresa izturības fenoti…
Advances in the endoscopic management of malignant biliary obstruction
2020
Biliary obstruction is common in pancreatobiliary malignancies and has a negative impact on the patient’s quality of life, postoperative complications, and survival rates. Particularly in the last decade, there has been enormous progress regarding the diagnostic and therapeutic options in patients with malignant biliary obstruction. Endoscopy has given a new insight in this direction and novel techniques have been developed for the better characterization and treatment of malignant strictures. We herein summarize the available data on the different endoscopic techniques, and clarify their role in the diagnosis and treatment of malignant biliary obstructive disease. Finally, we propose an al…

On the structural optimization in presence of base isolating devices
2012
The minimum volume design of plane frames constituted by elastic perfectly plastic material and subjected to appropriate combinations of fixed, cyclic and dynamic loads is studied. The influence on the design, in terms of cost (volume) and behavioural features, of seismic protecting devices is particularly focused. The considered protecting device is a lead rubber bearing base isolation system. Two optimal design problem formulations are proposed for the structure with or without the protecting device, both based on the so-called statical approach. The minimum volume frame is reached accounting for three different resistance limits: the purely elastic limit, the (elastic) shakedown limit an…
On the mechanism of radiation synthesis of nanogels
2016
Radiation-engineered poly(N-vinyl pyrrolidone) nanogels are very interesting biocompatible nanocarriers for i.v. administration of therapeutics and contrast agents for bioimaging among other applications. Nanogels are usually produced upon irradiation of dilute aqueous polymer solutions. Under these conditions, the polymer radicals formed primarily react via intramolecular radical-radical combination forming intramolecular crosslinks. The manufacturing process is fast and effective and grants excellent control of particle size and simultaneous sterilization of the formed nanogels. Interestingly, primary amino groups and carboxyl groups, useful for (bio)conjugation, are also formed in a dose…
Towards a Guidance System to Aid in the Dosimetry Calculation of Intraoperative Electron Radiation Therapy
2015
In Intraoperative Electron Radiation Therapy (IOERT), the lack of specific planning tools limits its applicability, the need for accurate dosimetry estimation and application during the therapy being the most critical. Recently, some works have been presented that try to overcome some of the limitations for establishing planning tools, though still an accurate guidance system that tracks, in real-time, the applicator and the patient is needed. In these surgical environments, the acquisition of an accurate 3D shape of the patient’s tumor bed in real-time is of high interest, as current systems make use of a 3D model acquired before the treatment. In this paper, an optical-based system is pre…
Autorreflexión pedagógica
2019
The autobiographical reflection on school learning makes it possible to explain how personal life guidelines are loading teaching activity with experiences. Educational time does not consist only of a linear narration, but works as the evocation of temporal and spatial memories of an explanation of the present. Personal life is intertwined with school reflection to give meaning to what we decide from teaching
Uz stāstiem balstīti uzdevumi angļu valodas teksta izpratnes pilnveidei vidusskolā
2015
Diplomdarba nosaukums ir „Uz stāstiem balstīti uzdevumi angļu valodas teksta izpratnes pilnveidei vidusskolā”. Izvirzītais darba mērķis ir noskaidrot, kā uz stāstiem balstīti uzdevumi var palīdzēt pilnveidot vidusskolēnu teksta izpratni angļu valodas stundās. Atsevišķa gadījuma pētījums ir izvēlēts kā pētījuma metode, kas tika realizēts Siguldas Valsts ģimnāzijas 10. klases angļu valodas stundās. Tās dalībnieki bija 13 skolēni. Pētījuma laikā skolēni tika anketēti, analizēta skolēnu attieksme pret viņu obligātajiem mācību grāmatas tekstiem un viņu lasīšanas izpratne, aprakstīta skolēnu darbošanās angļu valodas stundās, kurās bija iekļauti uz stāstiem balstīti uzdevumi, un analizēta skolēnu …
