Comparison of crop water use efficiency with rotation and continuous cropping in an irrigated vertisol

Water use efficiency is a key issue for the Australian cotton industry. For the individual producer the focus is to maximise returns from a limited resource. However, the current debate on allocation of water between domestic, agricultural and environmental sectors, imposes additional significance to water use efficiency at the industry level. We are conducting a project that focuses on crop water use efficiency as a component of whole farm water use efficiency. This will be achieved by (i) identifying the current sources of variation in crop water use efficiency between production units and (ii) quantifying the contribution of rotation and tillage practices to the water use efficiency of irrigated or partially irrigated cotton crops. The aims are three fold..

Reporting of suspected dog-fighting to the police, RSPCA and equivalents by veterinary professionals in the UK

Dog fighting became unlawful in the UK in 1835, yet it continues today (as reported by the Royal Society for the Prevention of Cruelty to Animals (RSPCA) and Crown Prosecution Service), although with an unknown prevalence. We used an online questionnaire to (1) determine the occurrence of dogs suspected of use in fighting in UK veterinary practices; (2) explore relative reporting of incidents to police, RSPCA or equivalent charity by registered veterinary nurses (RVN) and veterinarians; and (3) determine factors influencing reporting. Emails (n=2493) containing the questionnaire were sent to UK veterinary practices: 423 questionnaires (159 by RVNs, 264 by veterinarians) were completed. One or more cases of dog fighting were suspected by 14.4 per cent of respondents in 2015; 182 cases suspected in total. Proportionately more RVNs suspected dog fighting than veterinarians (P=0.0009). Thirty-two respondents (7.6 per cent, n=422) claimed to have reported suspicions to the police, the RSPCA or equivalent charity previously; 59 respondents (14.2 per cent) had previously chosen not to. Reasons not to report included: uncertainty of illegal activity (81.4 per cent), fear of the client not returning to the practice (35.6 per cent) and concerns regarding client confidentiality (22.0 per cent). Further work is required to address under-reporting of dog fighting by veterinary professionals

Preliminary observation on response of waterlogged cotton to different doses of AVG application

The obvious symptoms of waterlogging response in cotton are leaf chlorosis (yellowing) and dropping squares & bolls. In addition, Huck (1970) showed that tap root growth stopped within 30 min of reducing the oxygen in the soils, and that the growing point of the root was completely dead within 3 hrs. In other plant species, these responses have been associated with the effect of ethylene, produced in response to lack of oxygen (Pratt, 1953; Jackson, 1984; 1985; Jackson & Drew, 1984; Raskin & Konde, 1984; Stead, 1985; Voesenek & Blom, 1989; Osborne, 1991;Reid & Wu, 1991; Brady & Speirs, 1991; Voesenek et al, 1992; Drew, 1997). Ethylene is known to accelerate premature senescence, defoliation and boll dehiscence in cotton (Hall et al, 1957; Kirzek, 1986), but the involvement of ethylene in cotton's response to waterlogging has not been demonstrated. AVG (aminoethoxyvinylglycine)is an inhibitor of ethylene production. It can be used to indicate the involvement of ethylene production in physiological processes. Improvements in commercial production of AVG provide an exciting opportunity to explore the importance of ethylene production in plant responses to waterlogging in the field. To achieve meaningful results, dose-response tests are necessary to establish the concentration of AVG that is high enough to inhibit ethylene formation while low enough to minimise nonspecific and possibly toxic effects to the plants from AVG itself(Jackson, 1991)

Why Compact Tori For Fusion?

A compact torus (CT) has a toroidal magnetic and plasma geometry, but is contained within a simply-connected vacuum vessel such as a cylinder. Spheromaks and field-reversed configurations fall into this category. Compact tori are translatable and have a high engineering beta. The primary benefit of CTs for fusion is the absence of toroidal field and Ohmic Heating coils and the many problems brought on by them. Studying fusion-relevant plasma in simply-connected geometries affords the world fusion program both physics and technology opportunities not found in other configurations. This paper outlines the technology and physics opportunities of compact tori, and presents a cost model based on geometry for comparison with less compact configurations

Simple and objective prediction of survival in patients with lung cancer: staging the host systemic inflammatory response

Background. Prediction of survival in patients diagnosed with lung cancer remains problematical. The aim of the present study was to examine the clinical utility of an established objective marker of the systemic inflammatory response, the Glasgow Prognostic Score, as the basis of risk stratification in patients with lung cancer. Methods. Between 2005 and 2008 all newly diagnosed lung cancer patients coming through the multidisciplinary meetings (MDTs) of four Scottish centres were included in the study. The details of 882 patients with a confirmed new diagnosis of any subtype or stage of lung cancer were collected prospectively. Results. The median survival was 5.6 months (IQR 4.8–6.5). Survival analysis was undertaken in three separate groups based on mGPS score. In the mGPS 0 group the most highly predictive factors were performance status, weight loss, stage of NSCLC, and palliative treatment offered. In the mGPS 1 group performance status, stage of NSCLC, and radical treatment offered were significant. In the mGPS 2 group only performance status and weight loss were statistically significant. Discussion. This present study confirms previous work supporting the use of mGPS in predicting cancer survival; however, it goes further by showing how it might be used to provide more objective risk stratification in patients diagnosed with lung cancer

The relationship between weight loss and interleukin 6 in non-small-cell lung cancer.

Markers of the inflammatory response, interleukin 6, C-reactive protein, albumin and full blood count, were measured in non-small-cell lung cancer (NSCLC) patients (n = 21) with and without weight loss ( > 5%). There were significant increases in circulating C-reactive protein (P < 0.001), interleukin 6 (P < 0.01) and platelets (P < 0.01) in the weight-losing group. Moreover, there was a statistically significant correlation (r = 0.785, P < 0.001) between interleukin 6 and C-reactive protein concentrations. These results are consistent with interleukin 6 and the acute phase response promoting weight loss in NSCLC

Aboriginal life pathways through multiple human service domains; administrative data linkage for policy

Aboriginal children and families face the highest levels of disadvantage of any population group in Australia across health, education, child protection, justice and other human service domains, but longitudinal data to inform policy is scant. The Western Australian Aboriginal Child Health Survey (WAACHS) is a population representative cross-sectional child development study of over 5,000 randomly selected children aged 0-17 years, plus their families and schools, conducted between 2000 and 2002. This project seeks to leverage the WAACHS by linking the survey data for all participants with State administrative human services data registers from the previous 30+ years, to develop a major program of work in Aboriginal Human Development that would be unique in the world. This presentation describes the project history, novel survey linkage methodology, and project aims in the policy domain

Improving temperature‐based predictions of the timing of flowering in cotton

Key management recommendations for cotton (Gossypium hirsutum L.) management require estimates of the timing of crop phenology. Most commonly growing day degree (DD) (thermal time) approaches are used. Currently, across many cotton production regions, there is no consistent approach to predicting first square and flower timing. Day degree approaches vary considerably, with base thresholds different (12.0–15.6 °C) with no consistency using an optimum temperature threshold (i.e., temperature where development ceases to increase). As cotton is grown in variable and changing climates, and cultivars change, there is a need to ensure the accuracy of this approach for predicting timing of flowering for assisting cotton management. In this study new functions to predict first square and first flower were developed and validated using data collected in multiple seasons and regions (Australia and the United States). Earlier controlled environment studies that monitored crop development were used to assess in more detail how temperatures were affecting early cotton development. New DD functions developed predicted first square and first flower better than the existing Australian and U.S. approaches. The best performing functions had base temperatures like those of existing U.S. functions (15.6 °C) and an optimum threshold temperature of 32.0 °C. New universal DD targets for first square (343 DD [°C]) and first flower (584 DD) were developed. Controlled environment studies supported this base temperature outcome; however, it was less clear that 32.0 °C was the optimum threshold temperature from these data. Precise predictions of cotton development will facilitate accurate growth stage assessments and hence better cotton management decisions

Language attitudes and use in a transplanted setting: Greek Cypriots in London

In this paper we explore language attitudes and use in the Greek Cypriot community in London, England. Our study is based on an earlier survey carried out in Nicosia, Cyprus and we compare attitudes to language and reported language use in the two communities. We thereby highlight the significance of sociolinguistic variables on similar groups of speakers. We further extend our investigation to include codeswitching practices in the London community. \ud Analysis of language attitudes and use within the Greek-Cypriot population of London, and comparisons with findings in Nicosia, reflect symbolic forces operating in the two contexts. Despite obvious differences between the two communities, (most obviously the official languages and distinct cultural backgrounds of the two nations), the Greek Cypriot Dialect continues to play an active role in both. English is however the ‘default choice‘ for young Cypriots in the UK and Standard Modern Greek occupies a much more limited role than in Cyprus. It is argued that differences in language attitudes and use can be interpreted in light of different market forces operating in the nation (i.e. Cyprus) and the Diaspora (i.e. UK)
