Wpływ porozumień Euroazjatyckiej Unii Gospodarczej na konkurencyjność sektora rolnego państw członkowskich

The purpose of this study is to obtain scientific and practical results aimed at the use of the advantages of integration processes within the Eurasian Economic Union to increase the sustainability and competitiveness of the development of sensitive industries of the agri-food sector in the Eurasian Economic Union member states. The assessment of the potential for export growth and the potential for import substitution was performed according to the methodology for assessing the potential for export growth and is based on previous research developments. The study assessed the impact of the Treaty on the Eurasian Economic Union on the stability and competitiveness of such processing industries as: canned milk (condensed and non-condensed products), cheese making, production of sunflower oil, sausages and white sugar. It has been established that competitive pressure from foreign producers in the context of the development of integration processes can revive the internal competitive environment.Celem niniejszego opracowania jest uzyskanie wyników naukowych i praktycznych mających na celu wykorzystanie zalet procesów integracyjnych w ramach Eurazjatyckiej Unii Gospodarczej dla zwiększenia zrównoważoności i konkurencyjności rozwoju wrażliwych branż sektora rolno-spożywczego w krajach Eurazjatyckiej Unii Gospodarczej. Ocena potencjału wzrostu eksportu i potencjału substytucji importu została przeprowadzona zgodnie z metodologią oceny potencjału wzrostu eksportu i opiera się na wcześniejszych osiągnięciach badawczych. W opracowaniu oceniono wpływ Traktatu o Unii Euroazjatyckiej na stabilność i konkurencyjność takich gałęzi przemysłu przetwórczego jak: konserwy mleczne (produkty skondensowane i nieskondensowane), serowarstwo, produkcja oleju słonecznikowego, wędlin i cukru białego. Ustalono, że presja konkurencyjna ze strony producentów zagranicznych w kontekście rozwoju procesów integracyjnych może ożywić wewnętrzne środowisko konkurencyjne

Images in some of the literary works of SEK Mqhayi

This thesis attempts to examine some of Mqhayi' s literary works to establish their merit in terms of the images that are realised. In the main this necessitates the evaluation of the literary and linguistic qualities of his contributions which include essays and lectures, poetry and the translation of UAdonisi waseNtlango. This thesis further analyses and interprets Mqhayi 's thoughts and ideas regarding politics, economy and religion. Mqhayi gives these a universal image which prevents the critic from viewing him only in an African sense. From this study, specific subjects such as ubuntu, education, Christianity, culture and nation building emerge as the cornerstones of his literary intentions. The thesis also analyses images which are portrayed through skilful use of language and literary devices to determine their relevance in the present South African situation. Mqhayi shows tremendous foresight by interpreting a present situation to determine the future. Some of his predictions which manifest themselves in no uncertain terms at the present moment arc given attention in this study. Mqhayi uses his imbongi poetic licence to criticise and resolve without alienating his people against what he perceives to be wrong in society relating to culture, modern education, politics, economics and Christianity. In his opinion western values should not replace traditional Xhosa values, but a situation of compromise should be created which would result in a reconciliation of traditions. In the analysis and interpretation of his views it becomes clear that his focus and emphasis is on similarities which by far oumumber differences as a yardstick for better understanding. His translations from English literature and especially from Afrikaans (UAdonisi waseNtlanga) which he learned through self-tuition show a concerted attempt to bridge cultural and ideological divisions. In the final analysis the study of Mqhayi, other than revealing his exceptional literary ability establishes his supreme belief mirrored in his essays and poetry, that blacks and whites of this country should seek a radical break vvith the past and embrace the future as a people.African LanguagesD.

Generation and control of non-local quantum equivalent extreme ultraviolet photons

We present a high precision, self-referencing, common path XUV interferometer setup to produce pairs of spatially separated and independently controllable XUV pulses that are locked in phase and time. The spatial separation is created by introducing two equal but opposite wavefront tilts or using superpositions of orbital angular momentum. In our approach, we can independently control the relative phase/delay of the two optical beams with a resolution of 52 zs (zs = zeptoseconds). In order to explore the level of entanglement between the non-local photons, we compare three different beam modes: Bessel-like, and Gaussian with or without added orbital angular momentum. By reconstructing interference patterns one or two photons at a time we conclude that the beams are not entangled, yet each photon in the attosecond pulse train contains information about the entire spectrum. Our technique generates non-local, quantum equivalent XUV photons with a temporal jitter of 3 zs, just below the Compton unit of time of 8 zs. We argue that this new level of temporal precision will open the door for new dynamical QED tests. We also discuss the potential impact on other areas, such as imaging, measurements of non-locality, and molecular quantum tomography.Comment: 11 pages 5 figures and supplemental materials with 12 pages and 7 figure

Ways to Enhance Students’ Learning Activities in the Context of Higher Education

The article aims to study scientific and methodological features of the ways to enhance students’ learning activities in the context of higher education. The study's theoretical significance is derived from the in-depth analysis of the development of students' learning activity. The study offers the framework of characteristics for the concept of “students' learning (cognitive) activity". The main used methods were: analysis, peer-assessment, self-assessment. The interview method was used to make a cognitive profile of the participants, taking into account their psychological characteristics. The authors developed and scientifically tested educational model based on module curricula and interactive teaching methods to enhance students' learning activity. The authors also reflected the dynamic of the learning activity of the students with disabilities participating in the experiment. The results proved the effectiveness of the developed model of enhancing students' learning activity by using interactive teaching methods. It was concluded that the module curricular and active teaching methods help enhance students with disabilities' learning activity and make them more responsible in respect to the results of their study

Palladium catalysts supported on carbonized porous silicon for H2/O2 recombination

The article presents new research on the use of catalysts for H2/O2 recombination. The study emphasizes the importance of ensuring safe production, storage, and utilization of green hydrogen by recombining gas leaks. We suggest the utilization of innovative palladium catalysts for low-temperature hydrogen oxidation. These catalysts leverage molecular oxygen from the air to efficiently recombine small amounts of leaked hydrogen, resulting in the production of water. Recombination catalysts with a small amount of dispersed palladium metal on an inert support are the most efficient for production to prevent the risks of hydrogen explosion and fire. This study is focused on the development of laboratory prototypes for the H2/O2 recombination catalysts. We identified a potential catalytic system through monitoring of current literature to propose efficient hydrogen recombination catalysts. We present an optimized method for coating the surface of porous silicon nanoparticles with carbon layers, and introduce a technique for the production of supported palladium recombination catalysts. The proposed catalysts efficiently facilitate the recombination of hydrogen in lean air-hydrogen gas mixtures, offering a cost-effective alternative to more expensive commercial catalysts. Furthermore, they exhibit remarkable efficiency at both room and elevated temperatures. The final remarks underscore the necessity of creating new Pd catalysts to guarantee the secure storage and usage of hydrogen

Dissemination of a carbapenem-resistant acinetobacter baumannii strain belonging to international clone II/sequence type 2 and harboring a novel abar4-like resistance Island in Latvia

An outbreak of hospital-acquired Acinetobacter baumannii infections, caused by a blaOXA-23-positive carbapenem-resistant strain belonging to international clone II/ST2, was detected in Latvia. The strain was partially equipped with the armA gene and the intI1-aacA4-catB8-aadA1-qacE=1 class 1 integron. In addition, the strain carried AbaR25, a novel AbaR4-like resistance island of̃46,500 bp containing structures similar to the previously described AbaR22 and Tn6167 islands. AbaR25 was characterized by the occurrence of a second copy of Tn6022a interrupted by Tn2006 carrying the blaOXA-23 gene.publishersversionPeer reviewe

Multi-omics comparison of malignant and normal uveal melanocytes reveals molecular features of uveal melanoma.

Uveal melanoma (UM) is a rare cancer resulting from the transformation of melanocytes in the uveal tract. Integrative analysis has identified four molecular and clinical subsets of UM. To improve our molecular understanding of UM, we performed extensive multi-omics characterization comparing two aggressive UM patient-derived xenograft models with normal choroidal melanocytes, including DNA optical mapping, specific histone modifications, and DNA topology analysis using Hi-C. Our gene expression and cytogenetic analyses suggest that genomic instability is a hallmark of UM. We also identified a recurrent deletion in the BAP1 promoter resulting in loss of expression and associated with high risk of metastases in UM patients. Hi-C revealed chromatin topology changes associated with the upregulation of PRAME, an independent prognostic biomarker in UM, and a potential therapeutic target. Our findings illustrate how multi-omics approaches can improve our understanding of tumorigenesis and reveal two distinct mechanisms of gene expression dysregulation in UM

Immune Reconstitution During the First Year of Antiretroviral Therapy of HIV-1-Infected Adults in Rural Burkina Faso

There are no data on the outcome of highly active antiretroviral therapy (HAART) in HIV-infected adults in rural Burkina Faso. We therefore assessed CD4+ T-cell counts and HIV-1 plasma viral load (VL), the proportion of naive T-cells (co-expressing CCR7 and CD45RA) and T-cell activation (expression of CD95 or CD38) in 61 previously untreated adult patients from Nouna, Burkina Faso, at baseline and 2 weeks, 1, 3, 6, 9 and 12 months after starting therapy. Median CD4+ T-cell counts increased from 174 (10th-90th percentile: 33-314) cells/µl at baseline to 300 (114- 505) cells/µl after 3 months and 360 (169-562) cells/µl after 12 months of HAART. Median VL decreased from 5.8 (4.6- 6.6) log10 copies/ml at baseline to 1.6 (1.6-2.3) log10 copies/ml after 12 months. Early CD4+ T-cell recovery was accompanied by a reduction of the expression levels of CD95 and CD38 on T-cells. Out of 42 patients with complete virological follow-up under HAART, 19 (45%) achieved concordant good immunological (gain of ≥100 CD4+ T-cells/µl above baseline) and virological (undetectable VL) responses after 12 months of treatment (intention-to-treat analysis). Neither a decreased expression of the T-cell activation markers CD38 and CD95, nor an increase in the percentage of naive T-cells reliably predicted good virological treatment responses in patients with good CD4+ T-cell reconstitution. Repeated measurement of CD4+ T-cell counts during HAART remains the most important parameter for immunologic monitoring. Substitution of repeated VL testing by determination of T-cell activation levels (e.g., CD38 expression on CD8+ T-cells) should be applied with caution

Proportions of CD4+ memory T cells are altered in individuals chronically infected with Schistosoma haematobium

Characterisation of protective helminth acquired immunity in humans or experimental models has focused on effector responses with little work conducted on memory responses. Here we show for the first time, that human helminth infection is associated with altered proportions of the CD4+ memory T cells, with an associated alteration of TH1 responses. The reduced CD4+ memory T cell proportions are associated with a significantly lower ratio of schistosome-specific IgE/IgG4 (marker for resistance to infection/re-infection) in uninfected older people. Helminth infection does not affect the CD8+ memory T cell pool. Furthermore, we show for the first time in a helminth infection that the CD4+ memory T cell proportions decline following curative anti-helminthic treatment despite increased CD4+ memory cell replication. Reduced accumulation of the CD4+ memory T cells in schistosome-infected people has implications for the development of natural or vaccine induced schistosome-specific protective immunity as well as for unrelated pathogens
