Krzysztof Czajkowski, Anna Pastuszczak, Rafal Kotynski

2017 19th International Conference on Transparent Optical Networks (ICTON) > 1 - 4

2017 19th International Conference on Transparent Optical Networks (ICTON)

Single pixel detectors find applications ranging from multispectral imaging, through polarimetric, 3d, and holographic imaging, up to optical encryption and imaging through scattering media, which are however all hindered by the high measurement and reconstruction times. In this paper we propose to reduce the required signal acquisition time by using non-ergodic stationary sampling correlated with...

Błogosławiona święta Gustawa Herlinga-Grudzińskiego w świetle kerygmatu. Interpretacyjna glosa

Krzysztof Czajkowski

Roczniki Humanistyczne > 2015 > 63 > 1: Literatura Polska > 157-169

Tematyka mariologiczna, stanowiąca integralną część opowiadania Gustawa Herlinga –Grudzińskiego oraz właściwe centrum jego dotychczasowych interpretacji, nie wyczerpuje złożonej semantyki tekstu, który manifestacyjnie – zważywszy na kontekst Rozmów w Dragonei – wyłamuje się z przynależności do literatury religijnej. Dopiero narzędzia, którymi dysponuje metoda kerygmatyczna, zainicjowana w badaniach...

Preparation of silver hollow nanostructures by plasmon-driven transformation

Sławomir Stasieńko, Jan Krajczewski, Sebastian Wojtysiak, Krzysztof Czajkowski, more

Colloids and Surfaces A: Physicochemical and Engineering Aspects > 2014 > 443 > C > 102-108

Herein we demonstrate the synthesis of silver spherical hollow nanostructures by the plasmon-driven transformation (PDTr) of partially agglomerated silver sol. The PDTr process was carried out in the presence of oxygen and trisodium citrate using intensive 550–650nm light. In contrast to typical methods of the synthesis of metallic hollow nanostructures, no auxiliary template structures are used....

Nowotwory hematologiczne występują u ciężarnych z częstością 1:1000–1:10 000. Wśród tych nowotworów najczęstsze są chłoniaki (1:1000–1:6000), a w tej grupie – chłoniaki Hodgkina. W pracy opisano przypadek chłoniaka Hodgkina rozpoznanego w ciąży u 36-letniej kobiety. Współistnienie ciąży utrudnia zarówno rozpoznanie, jak i leczenie. Objawy przedmiotowe mogą nakładać się na dolegliwości towarzyszące...

Psychoneurocybernetic etiopathogenesis of cancers

Rudolf Klimek, Krzysztof Czajkowski, Zbigniew Kojs, Wiesław Szymański, more

Current Gynecologic Oncology > 2013 > 11 > 3 > 202–209

Multicellular organisms are composed of cells which psychoneurocybernetically match each other in terms of morphology (genetics), information and energy. The most incomprehensible disease, which has been a source of fear for centuries, took its name from crab-like (the word cancer is Latin for crab) or crayfish-like, as in some countries crabs are not found, growths that destroy human body. Cancers...

Janina Wojcicka-Bentyn, Krzysztof Czajkowski, Jacek Sienko, Monika Grymowicz, more

American Journal of Obstetrics and Gynecology > 2004 > 190 > 2 > 566-567

We report a case of a 25-year-old pregnant woman with gestational diabetes and increased activity (25-fold) of placental isozyme of alkaline phosphatase. Abdominal ultrasonographic scan revealed no hepatobiliary disease. After delivery, the alkaline phosphatase level decreased but did not return to the reference range. Similar abnormalities were found in the patient's first-degree relatives, which...

Abstract. The immunomodulatory effects of a recently synthesized adamantane derivative of aminopyridine 2-(1-adamantylamino)-6-methylpyridine (AdAMP) were tested on normal and neoplastic cells in vitro. When incubated with TNF- gene-transduced mouse melanoma cells (B78/TNF), AdAMP significantly enhanced basal production of TNF- by these cells, both by "high" and "moderate" TNF--producer...
