Electrooptic beam deflection with latex
1988
The use of latex in electrooptic devices is proposed. The static non linearity coefficient is shown to be approximatively 200 times the optical one. The theory of a beam deflector is developed and an explicit expression is given for the deflection angle versus the physical parameters of the sample Utilisation de suspensions aqueuses de latex dans un dispositif electro-optique. On montre que le coefficient statique de non-linearite devrait etre 200 fois plus eleve que le coefficient optique. Application a un deflecteur optique
La sensación sonora y visual del mar en la pintura valenciana de finales del siglo XIX
2010
This work presents an interpretation from a phenomenological point of view of the visual and sonorous experience on the perception of the sea in the context of XIX century Valencian painting. The use of senses to generate images of the sea establishes a network of links between them that plays a key role in the comprehension and interpretation of its image. The analysis starts from the identification of an autonomous and separated poetics of the sea, focusing on the study of its immensity from the different points of view that its contemplation presents. It ends on the interpretation of the sonorous and mobile potentiality of its matter. The study has identified in the chosen images of the …
Presencia de la langosta. Plagas en la Valencia bajomedieval
1997
La documentación municipal de Valencia es la base de este trabajo, en el que se precisa la cronología de las plagas de langosta que padecieron los campos del entorno de la ciudad en los siglos XIV y XV, y se analiza su incidencia en la vida urbana.
ON THE “SOLAR SYSTEM SMALL BODIES” ASTROPLATE PROJECT OF THE UKRAINIAN VIRTUAL OBSERVATORY
2019
The UkrVO Joint Digital Archive of astro- plates and the newest digitized data processing services al- lowed us to form a new approach for the creation of catalogs of astrometric and photometric characteristics of the Solar System bodies. Given this, the main goal of this approach was not only to complete the processing with the best possi- ble accuracy of high-quality and unprocessed earlier photo- graphic observations of the Solar System bodies but also to find new original data from these observations. As a result, more than 6,500 new astrometric positions and stellar magnitudes of asteroids, and 3,036 positions of outer planets (Pluto, Uranus, Neptune, Saturn, Jupiter) and their satelli…
El ‘relato maravilloso’ como expresión mítica de la presencia o ausencia divina
2020
El relato maravilloso constituye un recurso eficaz que el mito proporciona a las sociedades antiguas para articular y dar explicación a la relación del hombre con la naturaleza y a la presencia o ausencia de la protección divina. The ‘wonderful story ’constitutes an effective resource that myth provides to ancient societies to articulate and explain man’s relationship with nature and the presence or absence of divine protection.
Lateral flow assays (LFA) as an alternative medical diagnosis method for detection of virus species: The intertwine of nanotechnology with sensing st…
2021
Viruses are responsible for multiple infections in humans that impose huge health burdens on individuals and populations worldwide. Therefore, numerous diagnostic methods and strategies have been developed for prevention, management, and decreasing the burden of viral diseases, each having its advantages and limitations. Viral infections are commonly detected using serological and nucleic acid-based methods. However, these conventional and clinical approaches have some limitations that can be resolved by implementing other detector devices. Therefore, the search for sensitive, selective, portable, and costless approaches as efficient alternative clinical methods for point of care testing (P…
Joseph Conrad-Korzeniowski, an English Writer with a Polish Soul: Joseph Conrad’s Polish Heritage
2018
The article presents a portrait of Joseph Conrad-Korzeniowski, an English writer with a Polish soul. Conrad—the last Polish Romantic—did not only manage to introduce Polish dreams and longings into English (and Western) literature, but also transformed the Polish experience into a universal one. Writing about exotic, faraway places, he disseminated myths concerning Polish national identity, chivalric tradition and the Polish Eastern Borderland atmosphere and ethos. Conrad, a very demanding writer, never presents ready-made answers, nor does he offer simple solutions to the problems of his protagonists. Moreover, everybody can understand Conrad in their own personal way, for he is perceived …
HIV/AIDS un drošībiskošanas koncepts: Dienvidāfrikas piemērs
2017
Veselības sektors savulaik tika izmantots kā rīks aparteīda varas uzturēšanai, tādējādi finanses veselības aprūpei tika sadalītas atbilstoši rasēm. Centieni situāciju labot noveda pie tā, ka valsts veselības aprūpes sektorā strādāja vien 20% no personāla, taču atlikušie 80% bija nodarbināti privātajā veselības aprūpes sektorā. Būtiskas pārmaiņas tika piedzīvotas tikai pēc pārejas uz demokrātisku pārvaldes sistēmu 1994.gadā. Valdībai bija grandiozi plāni un ieceres, kā uzlabot esošo situāciju, taču tā nebija rēķinājusies ar iepriekšējās valdības atstātajiem parādiem. Tādējādi, neskatoties uz Dienvidāfrikas zemes bagātībām un ekonomisko uzplaukumu, attīstībai, tostarp veselības aprūpes sistēm…
The ultrastructure of multinucleate giant cells
2002
Abstract A survey of the available ultrastructural data on physiologically and pathologically occurring and virally-induced multinucleate giant cells (MNGCs) is presented. Emphasis is initially placed upon the bone osteoclast, the skeletal muscle myotube and the placental syncytiotrophoblast. The widespread occurence of MNGCs in a range of pathological situations is discussed, with emphasis upon the broad involvement of the macrophage in inflammatory responses. Many viruses produce cell fusion in vivo and in vitro when cell cultures are infected. Several examples are given. A clear distinction is drawn between viral fusion from “without” and viral fusion from “within” the cell. The cytopath…
Evidence for a direct interaction of Rev protein with nuclear envelop mRNA-translocation system.
1991
The interaction of the Rev protein from human immunodeficiency virus type 1 (HIV-1) with the nucleocytoplasmic mRNA-transport system was investigated. In gel-shift assay, the recombinant Rev protein used in this study selectively bound to the Rev-responsive element (RRE) region of HIV-1 env-specific RNA. Nitrocellulose-filter-binding studies and Northern/Western-blotting experiments revealed an association constant of approximately 1 x 10(10) M-1. The Rev protein also strongly bound to isolated nuclear envelopes from H9 cells, containing the poly(A)-binding site (= mRNA carrier) and the nucleoside triphosphatase (= NTPase), which are thought to be involved in nuclear export of poly(A)-rich …
