Penal Communication in Crown Court Sentencing
… in sentencing remarks by judges in three Crown Court sites in South East England in order to form a sound basis for the evaluation of penal practices. It seeks specifically to uncover how, if at all, the notion of penal censure operates in this context. Sentencing is a key aspect of the …

Influence of Tooth Crown Size on Malocclusion
… crowding. The present study tested whether tooth crown dimensions (mesiodistal and buccolingual) differed in a sample of American white adult males with naturally-occurring good occlusions (n = 42) versus otherwise similar individuals who required orthodontic treatment to correct their …

Explorations with optically active, cage-annulated crown ethers.
A variety of optically active macrocyclic crown ethers that serve as "host" systems that are capable of differentiating between enantiomeric "guest" molecules during host-guest complexation have been prepared via incorporation of chiral elements into the crown ring skeleton. The ability of these …

Selection for partial resistance to crown rust in oat
<p>Crown rust, caused by the fungal pathogen, Puccinia coronata, severely reduces kernel quality and grain yield in oat. Partial resistance is considered to be a durable form of rust resistance. The objectives of this study were to evaluate the effectiveness of index selection as a method for …

HUMAN PREMOLAR CROWN SIZES ARE VARIABLE EVEN IN THE SAME MOUTH, WITH LOW TO HIGH POSITIVE CROWN SIZE CORRELATIONS AMONG PREMOLARS AND ALL MOLARS.
… in my sample. Next, I tested whether premolar crown sizes and size ratios estimated molar absolute sizes and size ratio patterns (e.g., M1>M2>M3). I also tested whether absolute sizes and size ratios of earlier initiating teeth estimate sizes and ratios of later initiating teeth. Material and …

Improving Tree Crown Mapping using Airborne LiDAR with Genetic Algorithms
… These mapping efforts use individual tree crown (ITC) recognition algorithms applied to LiDAR point clouds, which have complex parameter sets. Genetic algorithms (GA) have been demonstrated to be excellent function optimizers for very complex search spaces and perform well for parameter …

Synthesis of Crown Ether/Ammonium Salt for Electron Transfer Study
… organic complexes in this study are a series of crown ether/ammonium salt, which incorporate a redox partner on each component of the complex. The dimethoxynaphthalene redox donor was attached to the crown ether and a series of ammonium salts was synthesized which bear substituted quinone and …

Maxillary Incisor Crown Form and Crowding in Adolescent Orthodontic Patients
… crowding occurs when the mesiodistal tooth crown widths exceed the space available in the dental arch for proper alignment. Previous research dealing with this common orthodontic problem has measured mesiodistal (MD) tooth widths or <em>clinical</em> tooth height-to-width ratios from dental …

Post Harvest Treatment Effects on Crown-Cut Broccoli Shelf Life
… weight loss and glucosinolate retention in crown-cut heads of broccoli were studied. Oxygen and CO2 levels inside shrink wrap packages were also monitored. Shrink wrap packaging had a significant positive effect on hue angle (p<0.05). Packaging and post harvest cooling delay had no effect on …

Synthesis and characterisation of amides based on crown ether supramolecular gels
… We have synthesised supramolecular gels based on crown ether amides because amide moieties have been extensively used as supramolecular synthons to generate LMWGs with tuneable properties and crown ethers represent a group of compounds with an exceptional ability to selectively coordinate to ions …
