Opis:: The experiments aimed to investigate the conversion of somatic embryos of the tulip ‘Apeldoorn’ variety in an in vitro culture supplemented with some chosen compounds. Tulip somatic embryos in torpedo stage, obtained by indirect somatic embryogenesis were placed for 1 week on media containing growth regulators (5 ěM Picloram, 1 ěM 6-benzylaminopurine (BAP) – control) and abscisic acid (ABA), abscisic acid + fluridone, Etephon and Etephon + salicylic acid (SA). Then, the embryos were maintained in the dark or under light for 10 weeks. After time of experiment, the greatest percent of leaf-forming embryos (40 %) and the greatest number of leaves (3.6 leaves) were observed when the embryos were treated simultaneously with Etephon and salicylic acid. Light did not influence the number of newly developed leaves but significantly increased (vs dark) percentage of leaf-forming embryos on control media (from 0 to 24 %) and on Etephon-supplemented medium (from 4 to 24 %). Abscisic acid and abscisic acid + Fluridone supplementation inhibited organogenesis of leaves but only in the cultures maintained under light. Regeneration of leaves was not observed on the control media maintained in the dark and on the abscisic acid + fluridone-supplemented media under light.
W przeprowadzonym doświadczeniu badano konwersję zarodków somatycznych tulipana 'Apeldoorn' pod wpływem wybranych czynników kultury in vitro. Zarodki somatyczne tulipana, w stadium torpedy, uzyskane drogą pośredniej embriogenezy somatycznej, wykładano na okres 1 tygodnia, na pożywki zawierające substancje wzrostowe (5 M Picloram, 1 M 6-benzyloaminopuryna (BAP) - kontrola) oraz: kwas abscysynowy (ABA), kwas abscysynowy+Fluridon, Etefon i Etefon+kwas salicylowy (SA). Następnie zarodki umieszczano na 10 tygodni w warunkach zaciemnienia lub światła. Po upływie czasu trwania doświadczenia zaobserwowano, że pod wpływem jednoczesnego działania Etefonu i kwasu salicylowego uzyskano największy udział zarodków formujących liście (40 %) oraz największą liczbę wytworzonych liści (3,6 szt.). Światło nie miało wpływu na liczbę powstałych liści, natomiast istotnie zwiększyło udział tworzących je zarodków na pożywkach kontrolnych (z 0 do 24 %) i po zastosowaniu Etefonu (z 4 do 24 %) w porównaniu z zarodkami utrzymywanymi w ciemności. Dodatek kwasu abscysynowego oraz kwasu abscysynowego i Fluridonu hamował organogenezę liści, ale tylko w obecności światła. Nie obserwowano regeneracji liści na pożywkach kontrolnych w warunkach zaciemnienia oraz pod wpływem kwasu abscysynowego i Fluridonu na świetle.

Opis:: The paper presents experimental investigation of a horizontally suspended cable with an MR damper attached transversally near the support. The algorithm proposed to MR damper control employs the concept of emulation of a viscous damper wit h an optimal viscous damping coefficient. The algorithm is realized using a velocity feedback with damping force tracking control is applied. Free vibration of the cable with an MR damper operating in passive and controlled modes are investigated. The obtained results indicate that an appropriately controlled MR damper ensures a nearly constant damping level in a wide range of cable vibration amplitudes.
W artykule przedstawiono wyniki badań eksperymentalnych układu poziomo zawieszonej liny z tłumikiem MR dołączonym poprzecznie w pobliżu podpory. Do sterowania tłumikiem MR przyjęto koncepcję emulacji tłumika wiskotycznego o optymalnym współczynniku tłumienia. Algorytm sterowania zrealizowano przy wykorzystaniu sprzężenia od prędkości oraz nadążnego układu sterowania siłą tłumienia. Analizie poddano drgania swobodne liny z tłumikiem MR pracującym w trybie pasywnym oraz sterowanym. Wyniki badań wskazują, że opracowany algorytm sterowania pozwala na uzyskanie w przybliżeniu stałego poziomu tłumienia drgań liny w szerokim zakresie wartości amplitudy drgań.

Opis:: Tactical ad-hoc networks are evolving today towards complex heterogeneous networks in terms of architecture, protocols and security. Due to the difference in network resources and reliability, end-to-end quality of service provisioning becomes very challenging. If we also take into account communication issues such as unpredictable connectivity, preferential forwarding for special traffic classes, intermittency due to node or communication link failure, the problem is further aggravated. In this article, we examine the major challenges that must be solved in order to provide efficient QoS provisioning in the heterogeneous network. Finally we describe QoS-aware mechanisms for inter-domain and intra-domain heterogeneous networks, also including real-time services provision in highly mobilr environments.

Opis:: Recent studies show that a representative of phospholipids, namely lysophosphatidic acid (LPA) and its receptors (LPA1-3) play a significant role in the reproductive processes, i. a, in the modulation of the uterine contractility. The participation of LPA3 in the reproductive processes has been revealed in mice and has not been studied in gilts. Therefore, in the present study we investigated the role/action of LPA and its receptors LPA1, LPA2 and LPA3 on the contraction activity in the porcine uterus. The study was conducted on an experimental model in which the pig uterus consisted of the one whole uterine horn and a part of the second horn, both connected with the uterine corpus. Uterine strips consisting of the endometrium with the myometrium (ENDO/MYO) and myometrium (MYO) alone were collected on days 12-14 of the estrous cycle (control group; n = 5) or pregnancy (experimental group; n = 5). Two analogues of LPA at increasing doses were used: oleoyl-sn-glycero- 3-phosphate (L-α-LPA, a selective agonist of LPA1 and LPA2 receptors; 10-7 M; 10-6 M and 10-5 M) and 1-oleoyl-2-O-methyl-rac-glycerophosphothionate (OMPT, a selective agonist of LPA3 receptor; 68 nM; 136 nM and 680 nM). L-α-LPA caused an increase in the contraction tension, amplitude and frequency of ENDO/MYO from the uterine horn with the developing embryos. This effect was not observed in MYO in both groups examined. In the ENDO/MYO strips of the uterine horn with developing embryos, OMPT significantly increased the contraction tension at the highest dose (680 nM) and amplitude at all doses examined, while frequency of contractions was decreased at doses of 136 nM and 680 nM. In the MYO strips of the uterine horn with embryos a significant increase in the contraction tension and amplitude after the highest dose of OMPT was observed. The results obtained imply the important role of receptors LPA1 , LPA2 and LPA3 in the contraction activity of the porcine uterus during early pregnancy.

Opis:: Although prostaglandin E₂ (PGE₂) is a pro-inflammatory mediator, it also produces some effect which is anti-inflammatory in character. It is suggested that one of the mechanisms responsible for the latter effect is the increased synthesis of IL-10. The aim of this study has been to determine the influence of PGE₂ on IL-10 production by bovine CD⁴⁺ and CD⁸⁺ T cells and NK cells. With this aim, peripheral blood mononuclear cells collected from 12-month-old heifers (n = 10) were treated without or with PGE₂ (10⁻⁶ M). Flow cytometric analysis showed that PGE₂ caused a reduction in the percentage of IL-10 producing CD⁴⁺ T cells (P < 0.001), while leaving the secretion of this cytokine by CD⁸⁺ T cells and NK cells unaffected. This seems to indicate that PGE₂ in cattle does not produce an anti-inflammatory effect by increasing the synthesis of IL-10; contrary to this, it may aggravate an inflammatory response by inhibiting the secretion of this cytokine by CD⁴⁺ T cells.

Opis:: The present study describes the distribution of CD4+CD8+ double-positive (DP) T cells in various immune compartments of mice with ovalbumin (OVA)-induced allergic asthma. It was found that the absolute number of DP T cells was considerably increased in the mediastinal lymph nodes and lungs of asthmatic mice as compared with that determined in the healthy subjects. On the contrary, the absolute counts of DP T cells was significantly decreased in the head and neck lymph nodes, and in peripheral blood of OVA-immunized mice. These results suggest that DP T cells may be involved in the pathogenesis of allergic asthma.

Opis:: A series of PLGA (poly L-lactide-co-glycolide) based composites modified with gel-derived glasses in the form of foils were obtained by solvent casting procedure. As a modifier, glass particles with different chemical compositions from the CaO–SiO2, CaO–P2O5–SiO2,and Al2O3–SiO2 systems were used. All glasses were synthesized by the sol-gel process. Evaluation of bioactive properties of obtained composites was made on the basis of surface changes occurring during contact with simulated body fluid. The changes of Ca, P and Si ions concentration in SBF after incubation of composites were also measured. The result showed that all composites with bioglasses (CaO–SiO2, CaO–P2O5–SiO2) exhibit formation of calcium phosphates layer after SBF test, however, kinetics of Ca, Si ion release and P uptake from SBF was dependent on bioglass chemical composition. The higher solubility, as well as faster consumption of phosphorus from SBF, was observed for materials from CaO–SiO2 (T1/PLGA, S1/PLGA) compared to composites with respective bioglass particles from the CaO–P2O5–SiO2(T2/PLGA, S2/PLGA). Our results showed that rate of Si and Ca release from the gel-derived glasses and P uptake from SBF are dependent on both: the concentration of respective ions in the materials and the presence of phosphates in their structure. For materials modified with gel-derived glasses from Al2O3–SiO2 system no significant surface changes during contact with SBF were observed, and it seems that their behavior in physiological solution indicate that they are bio-inert materials.

Opis:: Fifth-generation (5G) technology is currently developing in mobile networks. The civilian 3rd Generation Partnership Project (3GPP) standard is the basis for this implementation. Higher throughput, network capacity, user density, and lower latency are the main advantages offered by 5G over Long Term Evolution (LTE) and older standards. For this reason, these advantages are increasingly recognized in critical mission and military solutions. However, the 5G technology utilization in military equipment requires a deep analysis of the 3GPP standard, especially regarding technological gaps, security, and use cases. This is particularly important in using communication equipment during armed conflicts. Such equipment must be characterized by greater security and reliability than civilian equipment. Currently, work and analyses in this area are realized by the European Defence Agency (EDA), North Atlantic Treaty Organization (NATO) Communications and Information Agency (NCIA), Allied Command Transformation (ACT), and NATO Science and Technology Organization (STO). In the Information Systems Technology (IST) Panel of the NATO STO, the research task group (RTG) "IST-187-RTG on 5G Technologies Application to NATO Operations" is working on this topic. This paper presents exemplary 5G use cases in the navy. We indicate potential advantages, problems, and technological gaps that should be solved before implementing 5G technology in naval systems.

Opis:: Although beneficial properties of mineral waters are acknowledged by law in many countries, the use of water for medicinal purposes is not universally accepted. Notably numerous waters (especially mineral and curative ones) have high concentrations of mineral and trace elements. These mineral waters are common on the market and their availability is not regulated by law. Due to the hazard of overdosing, quantification of trace elements and minerals seems to be necessary. The World Health Organization, European Standards and Polish Standards recommend different methods for elemental determination, i.e. spectrometry, photometry for zinc determination, colorimetry or spectrometry for copper, and ionic chromatography for calcium, chloride and fluoride. In this paper, alternative, electrochemical methods have been applied to determine zinc, copper, calcium, chloride and fluoride in most popular natural and curative waters from southern Poland. The determined elemental content varied between 3.85-33.54 μg L-1 for zinc, 85-15.33 μg L-1 for copper, 2.8-2433.63 mg L-1 for chloride, 0.4-1.66 mg L-1 for fluoride and 11.05-478.48 mg L-1 for calcium. The voltammetric method was tested according to the validation procedures, taking into account the following parametes: linearity range, limit of detection and limit of quantification and precision. The results show that the applied electroanalytical methods are suitable for determination of the selected elements in waters of natural origin, ensuring low instrumental and analysis costs while providing results comparable with ones achieved with recommended methods.
