Opis:: Reversible gates enable the creation of fault tolerant digital devices. The application of these gates allows safe control systems to be realized. At present, control systems based on relays are being replaced by systems based on computer technology. This technology allows the implementation of safe systems. Because this system is composed of many elements, it is very difficult to obtain a high safety level for it. The application of reversible logic in the synthesis of digital systems constitutes an alternative approach. The paper presents reversible gates along with examples of their usage in the synthesis of digital systems. The main advantage of reversible logic is the possibility of synthesis of self testing and fault tolerant circuits. The application of circuits based on reversible logic allows safe control systems to be developed. The paper also presents a proposal for the application of reversible logic in simple control systems.

Opis:: In this paper, hybrid diffractive-refractive multifocal intraocular lenses are proposed, which are intended to provide good visual acuity over a discrete spectrum of object distances most often encountered by patients. The proposed hybrid lenses have seven foci. It is shown that by the appropriate selection of modulation depth of a sinusoidal phase diffractive profile and the period of the sinusoid, sharp vision can be achieved for a set of distances such as 24, 29, 37, 49, 73, 145 cm, and infinity. Theoretical axial and lateral visual point spread functions are computed. An accommodative amplitude equivalent of the eye implanted with a multifocal intraocular lens is introduced and calculated for the proposed heptafocal intraocular lenses.

Opis:: Silicone hydrogel (SiHy) contact lenses are a common form of correction of refractive errors prescribed by eye care professionals around the world. SiHy lenses perform in a complex environment, which is the surface of the eye and the tear film. Therefore, they are exposed to various factors, such as lipid deposits. The aims of this paper are to review available scientific reports on the study of SiHy lens interactions with lipids and search for further research objectives. A total of 57 publications were identified and reviewed, from 2003 to 2020. In general, SiHy lenses are more likely to accumulate lipid deposits than traditional hydrogel lenses, although there are significant differences between SiHy lens materials that may result from different methods used in the studies. The review includes studies on various aspects of interactions between lenses and lipids, such as those concerning the effectiveness of lipids removal from lenses by care solutions. The conclusion points out future research directions, such as measurements of lipid diffusion in SiHy lens' matrices.

Opis:: Currently used, computer railway traffic control systems , communicate via standard digital interfaces: CAN, Ethernet or RS485. In order to carry out the proof of security, it is necessary to test the functioning of the interfaces under different conditions. The IBIS model (I/O Buffer Information Specification) was used to simulate the transmission of signals through interfaces. The article discusses the applied interface models and simulation results in various conditions. The presented results can be used to prove the safety of transmission in computer railway traffic control systems.

Opis:: The complete protocol for regeneration and long-term micropropagation of several Polish cultivars of pea (Pisum sativum L.) has been elaborated. The shoots were the most likely regenerated via de novo organogenesis. The adventitious buds formed in callus derived from cotyledons tissue adjacent to the axillary meristems of immature embryos. All cultivars' calli regenerated several shoots per explant on the MS medium supplemented with B5 vitamins and 4.5 mgl-1 of BAP, however some differences in regeneration capacity among cultivars were observed. The plantlets were subsequently micropropagated with slightly higher efficiency and preserving a good viability over the long-term culture on a medium containing 2.0 mgl-1 than one with 4.5 mgl-1 of BAP. The additional step of the pre-conditioning culture of multiplicated shoots on a medium with very low BAP concentration i.e. 0.02 mgl-1 was applied and appeared to be beneficial before rooting in vitro or grafting. The modified MS-derived medium with the half-strength of MS macroelements but with the full original dose of calcium and supplemented with B5 vitamins and 1.0 mgl-1 of NAA was developed for effective rooting. The shoots were also sufficiently transferred into ex vitro conditions using grafting. The majority of the regenerated plants had adapted to in vivo conditions in a greenhouse and subsequently has set seeds. The presented protocol provides relatively efficient rate of de novo pea regeneration and would be useful for Agrobacterium-mediated transformation purposes.

Opis:: The text concerns the literary presentation of experiencing time that was characteristic of Romantics. In his latest book, Piotr Śniedziewski mentions time as a problem considered by 19th-century artists several times. The article presents this issue using the current reflection on the experience (Frank Ankersmit’s “historical sublime experience”) and the findings concerning the impact of photography that has been developing rapidly since 1839, on the way the literary represented world is shaped, as well as the use of photography as a tool of analysing time (“the visual model of time”).

Opis:: In fungi transfer of the first mannosyl residue to proteins during their O-glycosylation is catalyzed by protein O-mannosyltransferases encoded by pmt genes. Disruption of the pmt1 gene in Trichoderma caused a significant decrease in the total activity of protein O-mannosyltransferases. Moreover, disruption of the pmt1 gene also led to osmotic sensitivity of the strain, indicating an essential role of the PMTI protein activity for cell wall synthesis. At the same time, the strain was defective in septa formation, producing only half the number of septa per unit length of hypha compared with the wild type. Disruption of the pmt1 gene decreased protein secretion but had no effect on glycosylation of secreted proteins, which suggests that PMTI protein O-mannosyltranferase does not take part in glycosylation of these proteins.

Opis:: Soft contact lenses are used worldwide to correct ametropia. This medical device should be fitted and systematically evaluated on the patient eye by eye care professionals. The examination should include an evaluation of lens deposits. The widespread use of silicone hydrogel (Si-Hy) lenses and their tendency to build up lipid deposits indicate that eye care professionals should pay special attention to this kind of deposits. This paper aims to analyze the opinions of Polish ECPs regarding deposits on contact lenses, particularly regarding lipids and Si-Hy lenses. Data were collected from 103 Polish eye care professionals through an online survey. Respondents reported that lipid deposits are most often present on Si-Hy lenses, and protein deposits occur most often on hydrogel lenses. Almost all of them declare that they evaluate deposits on contact lenses on follow-up visits, which concludes that this is an essential part of the lens selection process for them. Respondents believe that different lenses and lens care solutions vary in the context of their interaction with lipid deposits. These parameters should be considered at the time of product selection. Eye care professionals expect descriptions of lenses’ resistance to lipid deposits, and care solution effectiveness in reducing lipid deposits.
Miękkie soczewki kontaktowe służące do korekcji ametropii są powszechnie używane na całym świecie. Jako wyrób medyczny powinny być dopasowywane i systematycznie oceniane na oku pacjenta przez specjalistów ochrony wzroku. Badanie kontrolne powinno obejmować ocenę osadów na soczewkach. Powszechne stosowanie soczewek silikonowo-hydrożelowych (Si-Hy) i ich tendencja do odkładania się złogów lipidowych wskazują, że specjaliści ochrony wzroku powinni zwracać szczególną uwagę na ten rodzaj osadów. Celem niniejszej pracy jest analiza opinii polskich specjalistów ochrony wzroku w zakresie osadów na soczewkach kontaktowych, ze szczególnym uwzględnieniem lipidów i soczewek Si-Hy. Dane zebrano od 103 polskich specjalistów ochrony wzroku poprzez ankietę internetową. Respondenci wskazali, że osady lipidowe najczęściej występują na soczewkach Si-Hy, a osady białkowe na soczewkach hydrożelowych. Niemal wszyscy ankietowani deklarują, że oceniają osady na soczewkach kontaktowych podczas wizyt kontrolnych, co pozwala wnioskować, iż jest to dla nich istotna część procesu doboru soczewek. Respondenci uważają, że poszczególne soczewki i płyny do ich pielęgnacji różnią się w kontekście ich interakcji z osadami lipidowymi. Parametry te powinny być brane pod uwagę w momencie wyboru produktu dla pacjenta. Specjaliści ochrony wzroku oczekują opisów odporności soczewek na powstawanie osadów lipidowych oraz skuteczności płynów pielęgnacyjnych w redukcji osadów lipidowych.
