Thermographic detection of hidden archaeological features in a Cheshire thatched cottage, and related aspects of thermal performance : case study at Roadside Cottage

Thermography can be an important tool for professionals working with traditional buildings. It is recognised by Historic England as providing information on a variety of structural features within buildings. Infrared thermography (IRT) is an acknowledged retrofit tool for reducing carbon emissions from traditional buildings. The paper explores the potential application of thermography as a tool for detecting infrared images emitted by the internal plaster surface of a timber-framed thatched cottage, dating from the 15th/16th century to 20th century. The thermal irregularities from hidden timber features or structural renovations under the thatch can help improve understanding of the evolution of the building and establish the extent of surviving historical fabrics. The images from IRT investigations conducted under different temperature difference conditions in 2010 and 2012 have been compared against the features exposed when re-thatching the property and upgrading insulation levels in 2019. A follow-up survey was carried out in 2021. Related aspects of the thermal performance of the thatched envelope and the effect on internal temperature distribution have also been investigated. The IRT investigations at Roadside Cottage demonstrated the importance of maintaining sufficiently large temperature differences across thatched roof buildings to permit detection of thermal irregularities arising from hidden timber features

Sustainable bioethanol production combining biorefinery principles using combined raw materials from wheat undersown with clover-grass

To obtain the best possible net energy balance of the bioethanol production the biomass raw materials used need to be produced with limited use of non-renewable fossil fuels. Intercropping strategies are known to maximize growth and productivity by including more than one species in the crop stand, very often with legumes as one of the components. In the present study clover-grass is undersown in a traditional wheat crop. Thereby, it is possible to increase input of symbiotic fixation of atmospheric nitrogen into the cropping systems and reduce the need for fertilizer applications. Furthermore, when using such wheat and clover-grass mixtures as raw material, addition of urea and other fermentation nutrients produced from fossil fuels can be reduced in the whole ethanol manufacturing chain. Using second generation ethanol technology mixtures of relative proportions of wheat straw and clover-grass (15:85, 50:50, and 85:15) were pretreated by wet oxidation. The results showed that supplementing wheat straw with clover-grass had a positive effect on the ethanol yield in simultaneous saccharification and fermentation experiments, and the effect was more pronounced in inhibitory substrates. The highest ethanol yield (80% of theoretical) was obtained in the experiment with high fraction (85%) of clover-grass. In order to improve the sugar recovery of clover-grass, it should be separated into a green juice (containing free sugars, fructan, amino acids, vitamins and soluble minerals) for direct fermentation and a fibre pulp for pretreatment together with wheat straw. Based on the obtained results a decentralized biorefinery concept for production of biofuel is suggested emphasizing sustainability, localness, and recycling principle

Priority Outcomes in Critically Ill Children: A Patient and Parent Perspective

BACKGROUND: Outcomes in pediatric critical care research are typically selected by the researcher. OBJECTIVES: (1) To identify outcomes prioritized by patients and their families following a critical illness and (2) to determine the overlap between patient-centered and researcher-selected study outcomes. METHODS: An exploratory descriptive qualitative study nested within a longitudinal cohort study conducted in 2 pediatric intensive care units (PICUs). Participants were purposively sampled from the primary cohort to ensure adequate demographic representation. Qualitative descriptive approaches based on naturalistic observation were used to collect data and analyze results. Data were coded by using the International Classification of Functioning, Disability, and Health Children and Youth (ICF-CY) framework. RESULTS: Twenty-one participants were interviewed a mean of 5.1 months after PICU discharge. Outcomes fell into 2 categories: patient-centered and family-centered. In the former, diagnosis, survival, and prognosis were key priorities during the acute critical illness. Once survival appears possible, functioning (physical, cognitive, and emotional), and factors that influence recovery (ie, rehabilitation, environment, and quality of life) are prioritized. Family-centered outcomes consisted of parents\u27 psychosocial functioning and experience of care. Patient-centered outcomes were covered well by the selected study measures of functioning, but not by the clinical outcome measures. CONCLUSION: Functioning and quality of life are key patient-centered outcomes during recovery from critical illness. These are not well captured by end points typically used in PICU studies. These results justify the importance of patient- and family-centered outcomes in PICU research and a need to determine how these outcomes can be comprehensively measured

Developing a video expert panel as a reference standard to evaluate respiratory rate counting in paediatric pneumonia diagnosis: protocol for a cross-sectional study

INTRODUCTION: Manual counting of respiratory rate (RR) in children is challenging for health workers and can result in misdiagnosis of pneumonia. Some novel RR counting devices automate the counting of RR and classification of fast breathing. The absence of an appropriate reference standard to evaluate the performance of these devices is a challenge. If good quality videos could be captured, with RR interpretation from these videos systematically conducted by an expert panel, it could act as a reference standard. This study is designed to develop a video expert panel (VEP) as a reference standard to evaluate RR counting for identifying pneumonia in children. METHODS AND ANALYSIS: Using a cross-sectional design, we will enrol children aged 0–59 months presenting with suspected pneumonia at different levels of health facilities in Dhaka and Sylhet, Bangladesh. We will videorecord a physician/health worker counting RR manually and also using an automated RR counter (Children’s Automated Respiration Monitor) from each child. We will establish a standard operating procedure for capturing quality videos, make a set of reference videos, and train and standardise the VEP members using the reference videos. After that, we will assess the performance of the VEP as a reference standard to evaluate RR counting. We will calculate the mean difference and proportions of agreement within±2 breaths per minute and create Bland-Altman plots with limits of agreement between VEP members. ETHICS AND DISSEMINATION: The study protocol was approved by the National Research Ethics Committee of Bangladesh Medical Research Council, Bangladesh (registration number: 39315022021) and Edinburgh Medical School Research Ethics Committee (EMREC), Edinburgh, UK (REC Reference: 21-EMREC-040). Dissemination of the study findings will be through conference presentations and publications in peer-reviewed scientific journals

Preliminary results on Saturn's inner plasmasphere as observed by Cassini: Comparison with Voyager

We present an analysis of Saturn's inner plasmasphere as observed by the Cassini Plasma Spectrometer ( CAPS) experiment during Cassini's initial entry into Saturn's magnetosphere when the spacecraft was inserted into orbit around Saturn. The ion fluxes are divided into two subgroups: protons and water group ions. We present the relative amounts of these two groups and the first estimates of their fluid parameters: ion density, flow velocity and temperature. We also compare this data with electron plasma measurements. Within the plasmasphere and inside of Enceladus' orbit, water group ions are about a factor of similar to 10 greater than protons in number with number densities exceeding 40 cm(-3). Within this inner region the spacecraft acquires a negative potential so that the electron density is underestimated. The electron and proton temperatures, which could not be measured in this region by Voyager, are T similar to 2 eVat L similar to 3. Also, within this inner region the protons, because of a negative spacecraft potential, appear to be super-corotating. By enforcing the condition that protons and water group ions are co-moving we may be able to acquire an independent estimate of the spacecraft potential relative to that estimated when comparing ion-electron measurements. Using our estimates of plasma properties, we estimate the importance of the rotating plasma on the stress balance equation for the inner magnetosphere and corresponding portion of the ring current

Factors Associated With Healthcare Utilization Among Children With Noncardiac Chest Pain and Innocent Heart Murmurs

Objective To examine differences in factors related to health care utilization (HCU) among children eventually diagnosed with noncardiac chest pain (NCCP) or an innocent heart murmur (IHM). Methods 67 pediatric patients with NCCP and 62 with IHM and their parent/guardian completed paper-and-pencil measures of psychological functioning and past HCU during an initial visit to the cardiologist's office. Results Children with NCCP utilized significantly more health care services compared to their IHM counterparts in the year prior to their cardiology visit. Children in the NCCP group had higher internalizing and somatic symptoms, and their parents experienced more anxious symptoms, than those in the IHM group. For the NCCP group only, child and parent psychological symptoms and parent HCU were positively related to child HCU. Conclusions Results identify possible child and parent psychological factors that may be the focus of interventions to reduce high rates of HCU among children with NCCP

PeanutMap: an online genome database for comparative molecular maps of peanut

BACKGROUND: Molecular maps have been developed for many species, and are of particular importance for varietal development and comparative genomics. However, despite the existence of multiple sets of linkage maps, databases of these data are lacking for many species, including peanut. DESCRIPTION: PeanutMap provides a web-based interface for viewing specific linkage groups of a map set. PeanutMap can display and compare multiple maps of a set based upon marker or trait correspondences, which is particularly important as cultivated peanut is a disomic tetraploid. The database can also compare linkage groups among multiple map sets, allowing identification of corresponding linkage groups from results of different research projects. Data from the two published peanut genome map sets, and also from three maps sets of phenotypic traits are present in the database. Data from PeanutMap have been incorporated into the Legume Information System website to allow peanut map data to be used for cross-species comparisons. CONCLUSION: The utility of the database is expected to increase as several SSR-based maps are being developed currently, and expanded efforts for comparative mapping of legumes are underway. Optimal use of these data will benefit from the development of tools to facilitate comparative analysis

Female economic dependence and the morality of promiscuity

This article is made available through the Brunel Open Access Publishing Fund. Copyright @ The Author(s) 2014.In environments in which female economic dependence on a male mate is higher, male parental investment is more essential. In such environments, therefore, both sexes should value paternity certainty more and thus object more to promiscuity (because promiscuity undermines paternity certainty). We tested this theory of anti-promiscuity morality in two studies (N = 656 and N = 4,626) using U.S. samples. In both, we examined whether opposition to promiscuity was higher among people who perceived greater female economic dependence in their social network. In Study 2, we also tested whether economic indicators of female economic dependence (e.g., female income, welfare availability) predicted anti-promiscuity morality at the state level. Results from both studies supported the proposed theory. At the individual level, perceived female economic dependence explained significant variance in anti-promiscuity morality, even after controlling for variance explained by age, sex, religiosity, political conservatism, and the anti-promiscuity views of geographical neighbors. At the state level, median female income was strongly negatively related to anti-promiscuity morality and this relationship was fully mediated by perceived female economic dependence. These results were consistent with the view that anti-promiscuity beliefs may function to promote paternity certainty in circumstances where male parental investment is particularly important

Genetic association of CDC2 with cerebrospinal fluid tau in Alzheimer's disease

We have recently reported that a polymorphism in the cell division cycle (CDC2) gene, designated Ex6 + 7I/D, is associated with Alzheimer's disease (AD). The CDC2 gene is located on chromosome 10q21.1 close to the marker D10S1225 linked to AD. Active cdc2 accumulates in neurons containing neurofibrillary tangles (NFT), a process that can precede the formation of NFT. Therefore, CDC2 is a promising candidate susceptibility gene for AD. We investigated the possible effects of the CDC2 polymorphism on cerebrospinal fluid (CSF) biomarkers in AD patients. CDC2 genotypes were evaluated in relation to CSF protein levels of total tau, phospho-tau and beta-amyloid (1-42) in AD patients and control individuals, and in relation to the amount of senile plaques and NFT in the frontal cortex and in the hippocampus in patients with autopsy-proven AD and controls. The CDC2 Ex6 + 7I allele was associated with a gene dose-dependent increase of CSF total tau levels (F-2,F- 626 = 7.0, p = 0.001) and the homozygous CDC2Ex6 +7II genotype was significantly more frequent among AD patients compared to controls (p = 0.006, OR = 1.57, 95% CI 1.13-2.17). Our results provide further evidence for an involvement of cdc2 in the pathogenesis of AD. Copyright (C) 2005 S. Karger AG, Basel
