Responses of spring wheat ‘Monsun’ and spring rye ‘Bojko’ on the late autumn terms of sowing
No full textW latach 2009-2013 przeprowadzono badania na dwóch niezależnych doświadczeniach polowych w Stacji Badawczej Wydziału Rolnictwa i Biotechnologii UTP w Bydgoszczy, zlokalizowanej w Mochlu (gmina Sicienko, województwo kujawsko-pomorskie). Celem było zbadanie reakcji pszenicy jarej 'Monsun' i żyta jarego 'Bojko' na wczesnojesienny i późnojesienny termin siewu w porównaniu z siewem wiosennym. Pszenica wysiewana była na glebie kompleksu pszennego słabego lub wadliwego, żyto na glebie kompleksu żytniego słabego. Obydwa gatunki wysiewano w dwóch terminach jesiennych, tj. jako wczesna przewódka (WP) 30 IX-5 XI, późna przewódka (PP) 10 XI-15 XII i na wiosnę (W) 3 III-5 IV. Pozytywną reakcję w plonie ziarna na jesienne terminy wysiewu stwierdzono u obydwu gatunków. Dla pszenicy 'Monsun' bardziej korzystne pod względem plonowania i jakości ziarna okazały się siewy w późniejszym terminie (listopad-grudzień), a dla żyta 'Bojko' we wcześniejszym terminie siewu (październikowym). Wyższe plonowanie obydwu zbóż po siewie przewódkowym wynikało z lepszego wypełnienia kłosa i dorodności ziarna.To meet the needs for cognitive and practical issues related to the cropping of wheat and rye this study was planned and conducted. The aim of the two independent field trials was to investigate the responses of spring wheat 'Monsun' and spring rye 'Bojko' to the sowing terms in late autumn. The investigation was carried out on the basis of two independent, strict field experiments in 2009-2013, at the Experimental Station of the Faculty of Agriculture and Biotechnology, UTS in Bydgoszcz, located in Mochełek, Kuyavian--Pomeranian region. In the first experiment, the soil of III-IV class according to Polish soil classification, wheat weak or defective complex, investigated the effect of sowing date on yield, yield components and grain quality of spring wheat 'Monsun' includes the following sowing terms: early autumn (early facultative) from 30 September to 5 November; late autumn (late facultative) from 10 November to 15 December, spring from 25 March to 5 April. The same treatments in the second experiment included sowing terms for rye: early facultative 10-15 October, late facultative 5-15 November and spring from 3 March to 1 April. The forecrop for rye was triticale and the soil was V class according to Polish soil classification. Average highest grain yield was obtained after sowing in late autumn terms - 5.83 t∙ha-1, with respect to the average yield of the early facultative crop was higher by 1.03 t. The same wheat sown in the spring obtained an average yield of 5.58 t∙ha-1, which did not differ significantly from late facultative crop. High values of the parameters responsible for the flour and backing obtained from grain, which came from late facultative wheat, e.g. sedimentation rate of 57.5 cm3 and a gluten content of 32.6%. In these respects is superior to wheat sowing spring and early autumn. It was found positive response 'Bojko' spring rye sowing on an earlier facultative term of sowing, i.e. 10-15 of October. The average yield for this date amounted to 3.08 and 0.5 t∙ha-1 was higher than the yield from the date of late autumn and 0.7 t of spring sowing. Higher yields of both cereals after facultative sowings resulted from higher kernels number per ear and grain plumpness
Wave turbulence of a rotating array of quantized vortices in the T → 0 temperature limit
No full textThe dynamics of quantized vortices in the zero temperature limit is currently of great interest, particularly in the case of the Fermi superfluid He-B. Here we study wave turbulence, generated by the librating motion of a rotating cylindrical container filled with He-B, in the limit of vanishing viscous forces at temperatures . The polarization of the quantized vortices with respect to the axis of rotation is measured using non-invasive NMR techniques. We observe a decrease of the polarization when the librating motion is started, and a two-stage relaxation process when the modulation of the rotation velocity is stopped. The first relaxation process is associated with the dissipation of large-scale flow stored in inertial waves and the solid body rotation of the vortex array. From the decay of these energy reservoirs we determine the rate of energy dissipation of large-scale flow. The later second process is related to the relaxation of Kelvin waves on individual vortices. This process is monitored by the recovery of the polarization. The existence of a Kelvin wave cascade at the lowest temperatures is currently a central open question. We supply some evidence for the cascade
Design and Analysis of a Distributed TRIC concept Seamless Smart Morphing Wing
No full textThis thesis embarked upon establishing and validating a design process to build and control a distributed TRIC concept seamless smart morphing wing to achieve simultaneous load alleviation, flutter suppression and drag minimization capabilities. A novel aeroelastic simulation tool was built to carry out composite wing skin optimization, with prototype testing carried out to design a flexible connection between modules. The work output was a fully built morphing wing which was successfully tested in the TU Delft Open Jet Facility. Control of the wing was partially made feasible through the development of a surrogate model of the system which was also validated with DIC testing.https://www.youtube.com/watch?v=SdagIiYRWyA&t=1s Smart-X Alpha DemonstratorAerospace Engineerin

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
Get PDFIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Measuring industry-science links through inventor-author relations: A profiling method
Get PDFIn this pilot study we examine the performance of text-based profiling in recovering a set of validated inventor-author links. In a first step we match patents and publications solely based on their similarity in content. Next, we compare inventor and author names on the highest ranked matches for the occurrence of name matches. Finally, we compare these candidate matches with the names listed in a validated set of inventor-author names. Our text-based profile methodology performs significantly better than a random matching of patents and publications, suggesting that text-based profiling is a valuable complementary tool to the name searches used in previous studies.innovation; industry-science links; text-based profiling;

Microbial enrichment culture responsible for the complete oxidative biodegradation of 3‑Amino-1,2,4-triazol-5-one (ATO), the reduced daughter product of the insensitive munitions compound 3‑Nitro-1,2,4-triazol-5-one (NTO)
No full text3-Nitro-1,2,4-triazol-5-one (NTO) is one of the main ingredients of many insensitive munitions, which are being used as replacements for conventional explosives. As its use becomes widespread, more research is needed to assess its environmental fate. Previous studies have shown that NTO is biologically reduced to 3-amino-1,2,4-triazol-5-one (ATO). However, the final degradation products of ATO are still unknown. We have studied the aerobic degradation of ATO by enrichment cultures derived from the soil. After multiple transfers, ATO degradation was monitored in closed bottles through measurements of inorganic carbon and nitrogen species. The results indicate that the members of the enrichment culture utilize ATO as the sole source of carbon and nitrogen. As ATO was mineralized to CO₂, N₂, and NH₄⁺, microbial growth was observed in the culture. Co-substrates addition did not increase the ATO degradation rate. Quantitative polymerase chain reaction analysis revealed that the organisms that enriched using ATO as carbon and nitrogen source were Terrimonas spp., Ramlibacter-related spp., Mesorhizobium spp., Hydrogenophaga spp., Ralstonia spp., Pseudomonas spp., Ectothiorhodospiraceae, and Sphingopyxis. This is the first study to report the complete mineralization of ATO by soil microorganisms, expanding our understanding of natural attenuation and bioremediation of the explosive NTO.Journal ArticleFinal article publishe
