Three-electron two-centred bonds and the stabilisation of cationic sulfur radicals [PDF]

open access: yes, 2014
Electronic communication in biological systems is fundamental to understanding protein signalling and electron hopping pathways. Frequently studied examples are cationic radical methionine and its functional derivatives.

POLISH-UKRAINIAN MILITARY UNITS IN THE YEARS 1991-2018

open access: yesSecurity and Defence Quarterly, 2018
The history and traditions of Polish-Ukrainian military contacts are as rich as the relations between the two nations. Intensive military cooperation dates back to the mid-16th century and is connected with the pursuit of the military capabilities of the

On Fluxed Instantons and Moduli Stabilisation in IIB Orientifolds and F-theory [PDF]

open access: yes, 2011
We study the superpotential induced by Euclidean D3-brane instantons carrying instanton flux, with special emphasis on its significance for the stabilisation of Kahler moduli and Neveu-Schwarz axions in Type IIB orientifolds.

Lime stabilisation for earthworks: a UK perspective [PDF]

open access: yes, 2014
Lime stabilisation is a versatile technique applied during earthworks operations. Modern soil recycling units are much more efficient at pulverising fill material and intermixing the added binder/water than machinery available 20 years ago.

Optimal Control Problem and Its Solution in Class of Feasible Control Functions by Advanced Model of Control Object

open access: yesMathematics
This paper is devoted to the solution of the optimal control problem. The obtained control should be optimal in terms of quality criteria and, at the same time, feasible when implemented in the control object.

Modelling and Stabilisation of an Unconventional Airship: A Polytopic Approach

open access: yesAerospace, 2022
The paper presents the modelling and stabilisation of an unconventional airship. The complexity of such a new design requires both proper dynamic modelling and control. A complete dynamic model is built here.

Using the root spread information of pioneer plants to quantify their mitigation potential against shallow landslides and erosion in temperate humid climates [PDF]

open access: yes, 2016
The aim of this paper was to quantify the mitigation potential of pioneer herbs against shallow landslidesand erosion in temperate humid climates and to identify key plant information to aid species selectionfor slope stabilisation. The objectives ranged

An Effect of $\alpha'$ Corrections on Racetrack Inflation

open access: yes, 2006
We study the effects of $ \alpha '$ corrections to the K\"ahler potential on volume stabilisation and racetrack inflation. In a region where classical supergravity analysis is justified, stringy corrections can nevertheless be relevant for correctly ...

Stabilisation of metals in mine spoil with amendments and growth of red fescue in symbiosis with mycorrhizal fungi

open access: yesPlant, Soil and Environment, 2006
Metal stabilisation effects of amendments (1% m/m CaCO3-L, 5% m/m municipal sewage sludge compost-MSSC, and 7.5% m/m natural zeolite-Z) were studied on acidic mine spoil (pHKCl 3.73) from Gyöngyösoroszi (Hungary) containing Cd-15.0, Cu-336, Mn-568, Pb ...
