A fluorescence study of the loading and time stability of doxorubicin in sodium cholate/PEO-PPO-PEO triblock copolymer mixed micelles
2019
Abstract Hypothesis Doxorubicin hydrochloride (DX) is one of the most powerful anticancer agents though its clinical use is impaired by severe undesired side effects. DX encapsulation in nanocarrier systems has been introduced as a mean to reduce its toxicity. Micelles of the nonionic triblock copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) (PEO-PPO-PEO), are very promising carrier systems. The positive charge of DX confines the drug to the hydrophilic corona region of the micelles. The use of mixed micelles of PEO-PPO-PEO copolymers and a negatively charged bile salt should favour the solubilization of DX in the apolar core region of the micelles. Experiments We st…
Video Scene analysis for a configurable hardware accelerator dedicated to Smart Camera
2012
International audience; According to the Center for Research and Prevention of Injuries report, fall-caused injuries of elderly people in UE- 27 are five times as frequent as other injury causes which reduce considerably their mobility and independence. Among the diverse applications of computer vision systems, object detection and event recognition are of the most prominent related recognition and motion analysis, that is, researchers had the idea to spread it in fall detection. The fall event, extracted automatically from the video scene represents itself, crucial information that can be used to alert emergency. In this context, visual information on the corresponding scene is highly impo…
FPGA-based smart camera : industrial applications
2013
International audience; For the last two decades and still today, smart cameras offer innovative solutions for industrial vision applications. This kind of system associates a flexible image acquisition with high-speed processing possibilities. Many smart camera designs are based on FPGA components to obtain these two features. Indeed, the FPGA enables the CMOS sensor to be controlled and therefore to propose a configurable acquisition according to the application constraints (i.e. dynamic windowing). The configurable structure of a FPGA represents a key advantage for modifying the embedded processing (even on-the-fly using dynamic reconfiguration). Meanwhile, FPGA components offer a large …
W kierunku sztuki radykalnej polityczności. O filmach politycznych boliwijskiego kolektywu Ukamau
2020
Tekst przedstawia rozważania na temat twórczości boliwijskiego reżysera filmowego, Jorge Sanjinésa w szerokim kontekście społeczno-politycznym i artystycznym. Autor analizuje również manifest teoretyczny Sanjinésa (1976), w których wyłożył on podstawowe założenia zaangażowanego kina politycznego w Ameryce Łacińskiej. Tezą nadrzędną artykułu jest twierdzenie, że filmy Sanjinésa należą do kina radykalnej polityczności. Jest to kino odsłaniające fundamentalne sprzeczności społeczne, a zarazem aktywnie nawołujące do zmiany niesprawiedliwych warunków w systemie. Istotnym wyróżnikiem tego typu aktywności twórczej jest więc nie to, że polega ona na opowiadaniu o zmianie politycznej, ale ma być pra…

Metsä- ja viljelysvarantojen estimointi miehittämättömästä lentolaitteesta
2012
Tutkielman yhtenä tavoitteena oli ensin selventää spektrikuvantamista ja mihin se perustuu. Tutkielmassa on käyty läpi myös spektrikuvantamisen historiaa lyhyesti. Tutkielman isona osana on selvitetty, minkälaista tutkimusta on tehty spektrikuvantamisen saralla, ja mikä on tämän päivän sovelluskenttä. Tutkimuksessa keskityttiin selvittämään, kuinka hyvin onnistuu metsä- ja viljelysvarantojen selvittäminen kevyellä lentolaitteella vääräväri- ja spektrikameran keinoin. ohtopäätösosassa on pohdittu, kuinka hyvin tutkimuksessa onnistuttiin vastamaan tutkimuskysymyksiin, ja lisäksi on vertailtu spektrikameran tuomia uusia näkökulmia väärävärikuvaukseen.

Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…
