Discovery of a new class of sortase a transpeptidase inhibitors to tackle gram-positive pathogens: 2-(2-phenylhydrazinylidene)alkanoic acids and rela…
2016
A FRET-based random screening assay was used to generate hit compounds as sortase A inhibitors that allowed us to identify ethyl 3-oxo-2-(2-phenylhydrazinylidene)butanoate as an example of a new class of sortase A inhibitors. Other analogues were generated by changing the ethoxycarbonyl function for a carboxy, cyano or amide group, or introducing substituents in the phenyl ring of the ester and acid derivatives. The most active derivative found was 3-oxo-2-(2-(3,4dichlorophenyl)hydrazinylidene)butanoic acid (2b), showing an IC50 value of 50 µM. For a preliminary assessment of their antivirulence properties the new derivatives were tested for their antibiofilm activity. The most active compo…
Modelling flow and heat transfer in spacer-filled membrane distillation channels using open source CFD code
2013
Abstract A good understanding of the details of hydrodynamic and heat transport conditions and their impact on temperature polarisation and pressure drops is essential for optimum design of membrane distillation (MD) modules. To this end, the present work reports on initial progress in the development of a tool for 3D simulation of spacer-filled MD channels based on the open source CFD code library OpenFOAM. The paper discusses a number of modelling and implementation aspects including model geometry and computational domain, choice of boundary conditions, and discretisation schemes. The results pertaining to the effect of three different spacer types on the fluid dynamics and heat transfer…
Friction and Heat Transfer in Membrane Distillation Channels: An Experimental Study on Conventional and Novel Spacers
2022
The results of an experimental investigation on pressure drop and heat transfer in spacer-filled plane channels, which are representative of Membrane Distillation units, are presented and discussed. Local and mean heat transfer coefficients were obtained by using Thermochromic Liquid Crystals and Digital Image Processing. The performances of a novel spacer geometry, consisting of spheres that are connected by cylindrical rods, and are hereafter named spheres spacers, were compared with those of more conventional woven and overlapped spacers at equal values of the Reynolds number Re (in the range ~150 to ~2500), the pitch-to-channel height ratio, the flow attack angle and the thermal boundar…
Multilevel functional surgery in adults with acquired spasticity of upper extremity
2004
The authors present their expertise in the treatment of acquired spasticity of the upper extremity in adults, illustrating the basics of modern functional surgery, which benefits from the achievements in bioengineering and information technology and new surgical techniques. Moreover close cooperation between the physical therapist and surgeon is essential in planning a new treatment scheme which, when possible, may successfully strengthen and optimize the function control of the remaining extremity, thus overriding the old concept of merely correcting the deformity. Results depend on proper scrutiny of the preoperative clinical and instrumental details on successful surgical accomplishment …
SCOPE-Based Emulators for Fast Generation of Synthetic Canopy Reflectance and Sun-Induced Fluorescence Spectra
2017
Progress in advanced radiative transfer models (RTMs) led to an improved understanding of reflectance (R) and sun-induced chlorophyll fluorescence (SIF) emission throughout the leaf and canopy. Among advanced canopy RTMs that have been recently modified to deliver SIF spectral outputs are the energy balance model SCOPE and the 3D models DART and FLIGHT. The downside of these RTMs is that they are computationally expensive, which makes them impractical in routine processing, such as scene generation and retrieval applications. To bypass their computational burden, a computationally effective technique has been proposed by only using a limited number of model runs, called emulation. The idea …
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.
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…
