A microsimulation calibration methodology based on speed-density relationships for freeways

2014

This paper describes the calibration methodology based on speed-density relationships in the microsimulation calibration process, stated that they represent the traffic flow phenomenon in a wide range of operational conditions and well summarize all the information that may be collected on field (or following a run of the microsimulation model) on two of the three key variables of traffic flow. The matching of speed-density relationships from field and simulation was evaluated using statistical analysis as technique of pattern recognition. A test freeway segment under uncongested traffic conditions was selected as case study; based on traffic data observed at A22 Brenner Freeway, Italy, sta…

Dynamika uwalniania azotu z nawozów o powolnym działaniu w eksperymencie laboratoryjnym

2016

Sustainable fertilization is one of the most important treatments of modern agriculture. Organic agriculture with new demands on agricultural practice, seeks to restrict the use of mineral fertilizers in favor of slow-action organic fertilizers. The fertilizers which are made on the farm are particularly valuable due to their quality and the absence of costs of purchase and transport. From this point of view, the new possibilities of using an organic matter which comes from waste of the food industry or biodegradable wastes from households proves to be interesting. Due to the absence of contamination with other types of waste, it can be used for the production of a fertilizer which could be…

Chromatin Maturity Index (CMI) in unfixed and live spermatozoa and Aniline Blue (AB) stained as an additional evaluation parameter in idiopathic male…

2021

Study question: To investigate whether idiopathic male infertility may be due to the presence of histones in motile spermatozoa using a modified AB staining protocol. Summary answer: No correlation between CMI in live motile spermatozoa, DNA Fragmentation Index (DFI) and other conventional seminal parameters were found in male infertile patients. What is known already: The AB stain discriminates between lysine-rich histones and arginine/cysteine-rich protamines. Transition from histones to protamines during spermatogenesis remodels chromatin packaging and abnormalities in the substitution of those proteins maybe interfere with seminal parameters and affect male infertility. The correlation …

Design Scheme of New Tetragonal Heusler Compounds for Spin-Transfer Torque Applications and its Experimental Realization

2012

Band Jahn-Teller type structural instabilities of cubic Mn(2)YZ Heusler compounds causing tetragonal distortions can be predicted by ab initio band-structure calculations. This allows for identification of new Heusler materials with tunable magnetic and structural properties that can satisfy the demands for spintronic applications, such as in spin-transfer torque-based devices.

Ultrafast Coherent THz Lattice Dynamics Coupled to Spins in the van der Waals Antiferromagnet FePS3

2022

Coherent THz optical lattice and hybridized phonon–magnon modes are triggered by femtosecond laser pulses in the antiferromagnetic van der Waals semiconductor FePS3. The laser-driven lattice and spin dynamics are investigated in a bulk crystal as well as in a 380 nm-thick exfoliated flake as a function of the excitation photon energy, sample temperature and applied magnetic field. The pump-probe magneto-optical measurements reveal that the amplitude of a coherent phonon mode oscillating at 3.2 THz decreases as the sample is heated up to the Néel temperature. This signal eventually vanishes as the phase transition to the paramagnetic phase occurs, thus revealing its connection to the long-ra…

Synthesis and Structure Elucidation of Novel Spirooxindole Linked to Ferrocene and Triazole Systems via [3 + 2] Cycloaddition Reaction

2022

In the present work, a novel heterocyclic hybrid of a spirooxindole system was synthesized via the attachment of ferrocene and triazole motifs into an azomethine ylide by [3 + 2] cycloaddition reaction protocol. The X-ray structure of the heterocyclic hybrid (1″R,2″S,3R)-2″-(1-(3-chloro-4-fluorophenyl)-5-methyl-1H-1,2,3-triazole-4-carbonyl)-5-methyl-1″-(ferrocin-2-yl)-1″,2″,5″,6″,7″,7a″-hexahydrospiro[indoline-3,3″-pyrrolizin]-2-one revealed very well the expected structure, by using different analytical tools (FTIR and NMR spectroscopy). It crystallized in the triclinic-crystal system and the P-1-space group. The unit cell p…

Potencjał finansowy sportowych organizacji pożytku publicznego

2020

Struktura źródeł pochodzenia przychodów może oddziaływać na sposób funkcjonowania i zakres działań podejmowanych przez organizacje pozarządowe. Instytucjonalny system organizacji sportu, jak również zasady finansowania organizacji pozarządowych objawiają się tym, że jednym z głównych źródeł ich przychodów są środki publiczne. Dlatego założono, że udział środków publicznych w przychodach ogółem różnicuje społeczne organizacje sportowe. Uznano to za czynnik, który w świetle teorii zależności od zasobów oraz zjawiska izomorfizmu instytucjonalnego może negatywnie kształtować warunki funkcjonowania organizacji pozarządowych. Celem badań było zidentyfikowanie struktury przychodów niekomercyjnych …

Dānijas sporta skolu sistēmas ieviešana Latvijā

2022

Šī bakalaura darba temats ir “Dānijas sporta skolu sistēmas ieviešana Latvijā”. Sports ir viens no sabiedrības labklājības stūrakmeņiem. Tas ir veids, kā cilvēks var justies labāk gan fiziski, gan mentāli. Tādēļ valsts vienam no mērķiem vienmēr būtu jābūt padarīt sportu pēc iespējas pieejamāku jebkuram, taču situācija Latvijas sporta sistēmā ir tāda, ka vēlme sportot uzliek lielu finanšu slogu lielo izmaksu dēļ, it īpaši runājot par vecākiem, kuri vēlas, lai viņu atvases aktīvi un regulāri sportotu. Darba mērķis ir ir salīdzināt Latvijas sporta skolu sistēmu ar Dānijas, lai noskaidrotu, kā var veiksmīgāk radīt sportistiem labvēlīgus apstākļus Latvijā. Darba empīriskajā daļā tiks veikta gadī…
