Decoding Pure Rotational Molecular Spectra for Asymmetric Molecules

In this paper we demonstrate how asymmetric molecular rotational spectra may be introduced to students both "pictorially" and with simple formulae. It is shown that the interpretation of such spectra relies heavily upon pattern recognition. The presentation of some common spectral patterns in near-prolate asymmetric rotational spectra provides a means by which spectral assignment, and approximate rotational constant determination, may be usefully explored in the physics and chemistry classrooms. To aid in this endeavor we have created a supporting, free, web page and mobile web page.Comment: 20 pages, 11 figure

Commissioning of the ATLAS Liquid Argon Calorimeters

A selection of ATLAS liquid argon (LAr) calorimeter commissioning studies is presented. It includes a coherent noise study, a measurement of the quality of the ionization pulse shape prediction, and energy and time reconstruction analyses with cosmic and single beam signals.Comment: Proceedings from the CIPANP 2009 Conferenc

Food neophobia and mealtime food consumption in 4-5 year old children.

Background: Previous research has documented a negative association between maternal report of child food neophobia and reported frequency of consumption of fruit, vegetables, and meat. This study aimed to establish whether neophobia is associated with lower intake of these food types in naturalistic mealtime situations. Methods: One hundred and nine parents of 4–5 year olds completed questionnaires which included a six-item version of the Child Food Neophobia Scale (CFNS). The children took part in a series of 3 test lunch meals at weekly intervals at school at which they were presented with: chicken, cheese, bread, cheese crackers, chocolate biscuits, grapes and tomatoes or carrot sticks. Food items served to each child were weighed before and after the meal to assess total intake of items in four categories: Fruit and vegetables, Protein foods, Starchy foods and Snack foods. Pearson Product Moment Correlations and independent t tests were performed to examine associations between scores on the CFNS and consumption during lunches. Results: Neophobia was associated with lower consumption of fruit and vegetables, protein foods and total calories, but there was no association with intake of starch or snack foods. Conclusion: These results support previous research that has suggested that neophobia impacts differentially on consumption of different food types. Specifically it appears that children who score highly on the CFNS eat less fruit, vegetables and protein foods than their less neophobic peers. Attempts to increase intake of fruit, vegetables and protein might usefully incorporate strategies known to reduce the neophobic response

Pre-letting of office developments : a guide for occupiers

‘Pre-letting’ is an agreement between a potential tenant and a developer to lease a building whose construction has not yet started. Benefits typically flow to both parties from a pre-letting, however, opportunities to pre-let are limited by place, time, market forces and the negotiation strength of both parties. This research bulletin, which has been produced jointly with Northumbria University, involved interviewing 30 office occupiers and developers who have been involved in prelet agreements throughout the UK. It examines the pros and cons of taking a pre-let, the typical lease terms, and design issues. It also looks at where and when pre-lettings are most likely to occur

Testing conformal mapping with kitchen aluminum foil

We report an experimental verification of conformal mapping with kitchen aluminum foil. This experiment can be reproduced in any laboratory by undergraduate students and it is therefore an ideal experiment to introduce the concept of conformal mapping. The original problem was the distribution of the electric potential in a very long plate. The correct theoretical prediction was recently derived by A. Czarnecki (Can. J. Phys. 92, 1297 (2014))

The effects of leaf litter treatments, post-harvest urea and omission of early season fungicide sprays on the overwintering of apple scab on Bramley’s Seedling grown in a maritime environment.

peer-reviewedThe theory that orchards with zero or low levels of apple scab post harvest do not need scab protection at the start of the next growing season was evaluated under Irish conditions. In addition, a range of post-harvest orchard sanitation practices (application of urea to rot overwintering leaves, mowing the orchard or total leaf removal in February) were also evaluated. Due to the high summer rainfall in Ireland (compared to all other European apple growing areas) and the severe susceptibility of the apple cultivar Bramley’s Seedling to scab (Venturia inaequalis), neither clean orchards in the autumn nor sanitation practices were sufficient to eliminate the requirement for full fungicide protection programmes at the start of the following growing season. Post harvest applications of urea proved difficult due to late harvesting of pollinator fruit for the juice market and wet weather. Total removal of leaf litter from plots prior to the commencement of growth did not significantly reduce disease incidence. Regardless of orchard cleanliness in autumn, missing the first fungicide application in the spring always reduced yield.This work was funded by the Department of Agriculture and Rural Development, Northern Ireland

Caseload midwifery in a multi-ethnic community: The women's experiences

Objective: To evaluate caseload midwifery in a relatively deprived and ethnically diverse inner-city area. Design and setting: Semi-structured interviews were undertaken with 24 women from diverse ethnic backgrounds, 12 of whom had received caseload care and 12 women from an adjacent area who had received conventional maternity care in a large inner-city maternity unit. Framework analysis was adopted drawing on links with the authors’ previous work on women’s views of caseload midwifery. Findings: Key themes from previous work fitted well with the themes that emerged from this study. Themes included ‘knowing and being known’, ‘person-centred care’, ‘social support’, ‘gaining trust and confidence’, ‘quality and sensitivity of care’ and ‘communication’. Key conclusions and implications: Women from this socially and ethnically diverse group of women had similar views and wanted similar care to those in previous studies of caseload midwifery. Many of the women receiving caseload care highlighted the close relationship they had with the midwives and as a result of thisfelt more able to discuss their concerns with them. This has the potential not only for improved quality of care but also improved safety
