Time-dependent modulation of genetic stability and phytochemical profiles in chrysanthemum leaves and inflorescences by iron oxide nanoparticles and IAA auxin
No full textThis research studied the impact of bare iron oxide nanoparticles (Fe3O4 NPs), citrate-stabilized iron oxide nanoparticles (Fe3O4CA NPs), and indole-3-acetic acid (IAA) on the genetic stability and metabolic activity of Chrysanthemum × morifolium (Ramat.) Hemsl. plants obtained from synthetic seeds. For this purpose, axillary buds of chrysanthemum ‘Richmond’ were embedded in 3% calcium alginate supplemented with NPs and IAA, either singularly or in combination. Next, the synthetic seeds were stored at 4 oC in the dark (for eight weeks) on an agar-water medium and then transferred to room temperature for 30 or 60 days. Next, the germinated seeds were transplanted to the greenhouse until the plants were fully flowering. The content of total polyphenols was determined in the leaves and inflorescences of the plants. Moreover, the content of anthocyanins was measured in the inflorescences. RAPD markers were used to assess the genetic stability of plants. It was found that NPs and IAA significantly affected the content of total polyphenols (TCP) in the leaves of chrysanthemum. Most treatments stimulated the accumulation of these compounds but in a time-dependent manner. No decline in the value of this parameter was reported compared with the untreated control. Conversely, Fe3O4NPs and IAA + Fe3O4CA NPs stimulated the biosynthesis of polyphenols and anthocyanins in the inflorescences after 30 days of treatment, however, a decline in the content of these compounds was reported after 60 days in most experimental objects, except for Fe3O4CA NPs and IAA + Fe3O4CA NPs. The inflorescences of plants treated with nanoparticles usually exhibited a larger diameter than the control, but only after a shorter exposure to the analyzed factors. In contrast, prolonged treatment resulted in the opposite effect. The genetic uniformity of the plants was confirmed with 2160 RAPD markers.</p

Enhancing GaN Nanowires Performance Through Partial Coverage with Oxide Shells
No full textResults posted here concern studies on GaN nanowires crystallised by molecular beam epitaxy coated with the wide bandgap oxides: AlOx and HfOx shells of nominal thickness varying from 1 to 20 nm, obtained via atomic layer deposition (ALD) . The scanning electron microscopy images show that the shells of different nominal thicknesses exhibit varying morphology. Specifically, as the number of ALD deposition cycles decreases, the shells take the form of islands. This leads to partial coverage of the nanowires. To explore the changes in the GaN core’s crystal lattice, strain was calculated based on X-ray diffraction, photoluminescence, and Raman spectroscopy. A great agreement between all techniques was found, indicating the presence of in-plane compressive strain.Moreover, in both photo- (PL) and cathodoluminescence (CL) spectra, luminescence enhancement was observed for the nanowires with partial coatings. The observation was confirmed through temperature-dependent PL and CL measurements . It was expected that the shells would enhance luminescence by passivating surface states and inducing a flat-band effect. However, we found that thick shells may reduce signal intensity by compromising structural quality, increasing strain gradient, and scattering light. Hence, the optimum shell thickness occurs when a balance between all these factors is achieved. What is more, the partial coating was confirmed to successfully protect nanowires against photoadsorption, despite their non-homogenity. We propose that the shells grow in the Stranski-Krastanov mode, which assumes that the additional monolayer is deposited prior to the formation of islands, providing sufficient protection for the cores.</p

Metafora śmierci i umierania w językach oshiwambo i otjiherero
No full textZe śmiercią i przemijaniem często staramy się oswoić i konstruować takie ich wyobrażenie, które byłoby dla nas łatwiejsze do zaakceptowania. Jednym z podstawowych narzędzi, które pomaga nam ten cel osiągnąć jest metafora.Działanie naukowe prowadzone w ramach grantu MINIATURA 7 koncentruje się na dwóch językach z rodziny bantu: oshiwambo i otjiherero.W Namibii, podobnie jak w innych częściach świata, śmierć i umieranie objęte są tabu kulturowym. Użytkownicy języków oshiwambo i otjiherero, tak jak użytkownicy innych języków naturalnych, często posługują się metaforą, aby opanować strach przed śmiercią i nadać śmierci trochę bardziej zrozumiałą i przyjazną formę.Istnieje luka badawcza, którą działanie ma wypełnić. W Namibii, po uzyskaniu niepodległości, status języka urzędowego nadano językowi angielskiemu, który obecnie praktycznie wyparł języki lokalne ze szkół, mediów, świata polityki czy biznesu. Dominacja języka angielskiego niestety spowodowała również mniejsze zainteresowanie językami lokalnymi ze strony językoznawców. Języki te zostały wprawdzie opisane (np. Fivaz 2003, Möhlig i Kavari 2008), lecz opisy te koncentrują się głównie na ich dystynktywnych cechach fonologicznych, morfologicznych czy składniowych. Niewiele uwagi poświęca się natomiast semantyce. Z moich ustaleń wynika, iż metaforyka języków oshiwambo i otjiherero, szczególnie metafora śmierci, nie została udokumentowana. Nieliczne opisy, które można odnaleźć dotyczą innych subsaharyjskich języków afrykańskich lub innej tematyki. Na przykład Owiredu (2020) porusza temat metafory śmierci w języku akan, Siemiątkowska (2006) w języku hausa, a Ohly (1998) pisze o metaforze w otjiherero, jednak jedynie w kontekście wybranych toponimów.Działanie naukowe prowadzone w ramach grantu MINIATURA 7 jest badaniem pilotażowym i ma pozwolić na lepsze poznanie języków oshiwambo i otjiherero i będzie stanowić uzupełnienie istniejącej literatury.Niniejszy zbiór danych zawiera:notatki sporządzone podczas rozmów z Paavo Hasheela - autorem wielu publikacji dotyczących oshikwanyama - jednego z dwóch dialektów języka oshiwambo,zapiski sporządzone podczas wywiadów z rodzimymi użytkownikami oshiwambo, otjiherero, xhosa i innych języków regionalnych.</ol

Simulations of optimal light polarization state generators and analyzers configurations realized in one-way double pass Mueller polarimetric system using twisted nematic liquid crystal and liquid crystal variable retarder
No full textThe dataset contains the results of optimizing the configurations of light polarization state generators and analyzers that can be implemented in one-way double pass Mueller polarimetric system. The same module is used as a generator (PSG) and analyzer (PSA) of different polarization states of light. In the performed numerical simulations, the PSG/PSA module is constructed from a linear polarizer, twisted nematic liquid crystal (TNLC) and liquid crystal variable retarder (LCVR).PSG/PSA descriptionThe elements of the system are represented by a Mueller matrices. The forms of the used Mueller matrices are included in the file: "Mueller_matrix.pdf". It was assumed that for PSG, TNLC director axis of the first layer is aligned along the x-axis of the coordinate system. However, for PSA, TNLC directors at the input surface of the modulator is rotated by an angle π/2. Due to the configuration, TNLC in the PSG and PSA system introduce the same linear phases. The dependence between the voltage of the TNLC and the induced phase difference is not considered. LCVR is set at the azimuth angle of 45° and introduces linear phase differences from the (0;2π>.Optimization processThe numerical PSG/PSA model were simulated and optimized to find the optimal sets of TNLC’s and LCVR’s linear phase differences for every linear polarizer’s azimuth angle, and thereby the best set of generators and analyzers, leading to the minimum system condition number (CN). Also equally weighted variance (EWV) is calculated. The results of optimization process were generated for:different ranges of possible TNLC’s linear phase difference: (0;2π>, (0;3π>, (0;4π>, (0;5π>,different number of configurations realized by PSG/PSA (n={4:20}),azimuthal orientations of the polarizer from 0°-180° with a step of 0.5°.For each azimuth angle of the polarizer randomly permuted n TNLC’s and LCVR’s linear phases and determination instrumental matrices for PSG (the columns of this matrix correspond to the n Stokes vectors of the PSG) and PSA (the rows of this matrix correspond to the n Stokes vectors of the PSA). CN of the polarimeter system was calculated as product of generator’s CN and analyzer’s CN. These steps have been repeated 10 000 times and the minimum CN value corresponding to a given polarizer azimuth angle was determined. Associated with this determined minimum CN value of the system are EWV value and sets of n TNLC’s and LCVR’S linear phases, leading to n Stokes vectors for PSG and PSA.Used software: MATLAB File information and data formatThe data are saved as text files (.txt) and MAT-files (.mat).The resulting files are grouped according to the assumed maximum linear phase difference introduced by TNLC (PDmax):maximum_linear_phase_difference_2pi.zip -> TNLC’s linear phases are generated from the range (0;2π>maximum_linear_phase_difference_3pi.zip -> TNLC’s linear phases are generated from the range (0;3π>maximum_linear_phase_difference_4pi.zip -> TNLC’s linear phases are generated from the range (0;4π>maximum_linear_phase_difference_5pi.zip -> TNLC’s linear phases are generated from the range (0;5π>.Inside, the folders are grouped according to the different number of configurations (n={4:20}). Names are created in this way: number_of_configurations_n.Each folder contains:CN_PSA_vs_alfaP_PDmax_n.txt -> The first row is the azimuth angles of the polarizer in radians, the second row is the CN values of the PSA instrumental matrix (corresponding to the minimum CN value of the system).CN_PSG_vs_alfaP_PDmax_n.txt -> The first row is the azimuth angles of the polarizer in radians, the second row is the CN values of the PSG instrumental matrix (corresponding to the minimum CN value of the system).CN _vs_alfaP_PDmax_n.txt -> The first row is the azimuth angles of the polarizer in radians, the second row is the minimum CN values of the system.EWV _vs_alfaP_PDmax_n.txt -> The first row is the azimuth angles of the polarizer in radians, the second row is the EWV values of the system (corresponding to the minimum CN value of the system).linear_phase1 _alfaP_PDmax_n.txt -> The first row is the azimuth angles of the polarizer in radians, the second row is the set of n TNLC’s linear phases in radians (corresponding to the minimum CN value of the system).linear_phase2 _alfaP_PDmax_n.txt -> The first row is the azimuth angles of the polarizer in radians, the second row is the set of n LCVR’s linear phases in radians (corresponding to the minimum CN value of the system).PSA_vs_alfaP_PDmax_n.mat -> For each azimuth angle of the polarizer saved matrix formed from the Stokes vectors of the analyzers (corresponding to the minimum CN value of the system). Each column is a new Stokes vector.PSG_vs_alfaP_PDmax_n.mat -> For each azimuth angle of the polarizer saved matrix formed from the Stokes vectors of the generators (corresponding to the minimum CN value of the system). Each column is a new Stokes vector.Cell array indices consistent with polarizer azimuth angle indices.Preferred software for analyzing/interpreting results: MATLAB.</p
The impact of the distribution method for struvite (Crystal Green) on the chemical composition of soybean and their utility in animal nutrition
No full textThe data are from chemical tests performed to determine an alternative source of phosphorus fertilizer and compare its impact on the chemical composition of soybean seeds with that of a traditional fertilizer (Super FOS DAR). In this file there are raw materials to evaluate nutritional value of soyabean under struvite fertilization. Use of struvite (Crystal Green) caused positive changes in selected amino acids content and in the nutritional value of protein in soybean seeds; this can enhance the value of soybean seeds as well as increase certain macroelements and microelements. Phosphorus fertilizer significantly increased the content of lysine, leucine, valine, phenyloalanine and tyrosine. Band fertilization with struvite caused a significant increase in amino acids (lysine, leucine, valine, phenyloalanine and tyrosine) as well as in the nutritional value of protein (as measured by the essential amino acid index, protein efficiency ratio and biological value of the protein). Favorable changes under the influence of the application of struvite were recorded in the content of calcium, as well as phosphorus, iron, and manganese. </p
