Abstract:
A systematic study of torsional potential curves in electronic ground state based on second-order Møller–Plesset energy (MP2), density functional theory (DFT), and Austin mode 1 (AM1) methods is presented for para-phenylenevinylene oligomers constructed from two to four aromatic rings. The semiempirical AM1 approach gives the correct location of potential energy minima in comparison with the reference MP2 calculations and literature data. However, the semiempirical AM1 energy barriers at perpendicular orientation are ca. 30% smaller than the MP2 ones. The DFT calculations indicate optimal plan

Abstract:
The experimentally motivated question of the acetylene bromoboration mechanism was addressed in order to suggest possible radical isomerization pathways for the syn-adduct. Addition–elimination mechanisms starting with a bromine radical attack at the “bromine end” or the “boron end” of the C=C bond were considered. Dispersion-corrected DFT and MP2 methods with the SMD solvation model were employed using three all-electron bases as well as the ECP28MWB ansatz. The rate-determining, elimination step had a higher activation energy (12 kcal mol−1) in case of the “bromine end” attack due to interme

Abstract:
The possible conformations in the most stable structure of cyclophosphamide were investigated at the DFT-B3LYP and MP2/6-311G** levels of calculation. The axial structure is calculated to be lower in energy than the equatorial form of cyclophosphamide by 5 (MP2) to 6 (DFT) kcal mol-1 because of a very weak anomeric effect and weak conjugation. Further it is the same structure as the one found in the X-ray investigations both of the hydrate and of the anhydrous form. The computed DFT vibrational frequencies of the axial structure were used to analyze the infrared and Raman spectra using normal-

Abstract:
The objective of this work is to use some machine learning algorithms and test its efficiency in developing models to predict Locked Wheel Skid Trailer (LWST) values from Dynamic Friction Tester (DFT) and Circular Texture Meter (CTM) measurements conducted on asphalt pavement surfaces. For this prediction, three models were developed using DFT measurements at different speeds starting from 20km/h (12.5 mph) up to 64 km/h (40 mph) and then same DFT measurements as combination with Mean Profile Depth (MPD) and the last model used the International Friction Index (IFI) parameters (F60 and SP).

Abstract:
Abstract The case presented in this paper is an HPHT exploratory well in East Borneo. This well was designed to drill a potential gas reservoir using MPD system to encounter the narrow operational window formation. An unexpected high pore pressure increase was detected while drilling the 8.5-inch hole section, resulting in a tighter window. The pore pressure below 9-5/8-inch casing shoe was measured to be 2.18 SG, up from 2.09 SG preliminary expectation. Because of this condition, it was decided to call in TD earlier and cement the open hole section using managed pressure cementing. Convention

Abstract:
A short but productive cruise aboard RV William Kennedy tested various new field equipment near Halifax (port of departure and return) but also in areas that could also benefit science understanding. The GSC-A Gavia Autonomous Underwater Vehicle equipped with bathymetric, sidescan and sub-bottom profiler was successfully deployed for the first time on Scotian Shelf science targets. It surveyed three small areas: two across known benthic sponge, Vazella (Russian Hat) within a DFO-directed trawling closure area on the SE flank of Sambro Bank, bordering Emerald Basin, and one across known pockmar

Abstract:
Denna studie, genomförd på uppdrag av Myndigheten för psykologiskt försvar (MPF), analyserar koranbränningarna i Sverige med särskilt fokus på åren 2020, 2022 och 2023, samt de omfattande säkerhetskonsekvenser som dessa händelser medfört. Syftet är att kartlägga händelseförloppet, analysera de säkerhetsmässiga konsekvenserna och identifiera de internationella narrativ som växt fram kring Sverige. Särskilt fokus ligger på att studera hur statliga aktörer som Ryssland, Kina och Iran har exploaterat koranbränningarna i syfte att underminera Sveriges internationella anseende. Studien kompletterar

Abstract:
Purpose/Background: Adverse Childhood Experiences (ACEs) have an impact on health throughout the lifespan (Filletti et al., 1999; Hughes et al., 2017). These experiences range from physical and mental abuse, substance abuse in the home, parental separation or loss, financial instability, acute illness or injury, witnessing violence in the home or community, and incarceration of family members (Hughes et al., 2017). Understanding and screening for ACEs in children with urinary incontinence can help practitioners identify psychological stress as a potentially modifiable risk factor. Methods: A 5
