Review of the flower-inhabiting water scavenger beetle genus Cycreon (Coleoptera, Hydrophilidae), with descriptions of new species and comments on its biology

The hydrophilid genus Cycreon Orchymont, 1919, previously known from two historical specimens only, is reviewed based on the numerous material collected recently from the inflorescences of various Araceae species in the Malay Peninsula and Borneo. Four species are recognized in the genus: C. sculpturatus Orchymont, 1919 from Sumatra, C. armandi Shatrovskiy, 2017 from Singapore, C. adolescens sp. n. from peninsular Malaysia, and C. floricola sp. n. with two subspecies, the nominotypical one from Peninsular Malaysia, and C. floricola borneanus subsp. n. from Borneo. All species are very similar, differing only by the pronotal punctation, shape of the clypeus and the mentum, and the form of the median lobe of the aedeagus. Specimens of C. floricola sp. n. and C. adolescens sp. n. were collected from inflorescences of various genera of the family Araceae. The field observations and analysis of mid gut contents indicates that they feed on organic material on internal organs of the inflorescences, including the pollen of the host plant. They were also observed to carry a large amount of pollen and are likely pollinators of their host species of Araceae

Hyades Oxygen Abundances from the k6300 [O i] Line: The Giant-Dwarf Oxygen Descrepancy Revisited

We present the results of our abundance analysis of Fe, Ni, and O in high signal-to-noise ratio, high-resolution Very Large Telescope UVES and McDonald 2dcoude´ spectra of nine dwarfs and three giants in the Hyades open cluster. The difference in Fe abundances derived from Fe ii and Fe i lines ([Fe ii/HÀ½Fe i/H)and Ni i abundances derived from moderately high-excitation ( %4:20 eV) lines is found to increase with decreasing Teff for the dwarfs. Both of these findings are in concordance with previous results of overexcitation/overionization in cool young dwarfs. Oxygen abundances are derived from the [O i] k6300 line, with careful attention given to the Ni i blend. The dwarf O abundances are in star-to-star agreement within uncertainties, but the abundances of the three coolest dwarfs (4573 K TeA 4834 K) evince an increase with decreasing Teff. Possible causes for the apparent trend are considered,including the effects of overdissociation of O-containing molecules.O abundances are derived from the near-UV OH k3167 line in high-quality Keck HIRES spectra, and no such effects are found; indeed, the OH-based abundances show an increase with decreasing Teff, leaving the nature and reality of the cool dwarf [O i]-based O trend uncertain. The mean relative O abundance of the six warmest dwarfs (5075 K TeA 5978 K) is ½O/H¼þ0:14 Æ0:02, and we find a mean abundance of ½O/H¼þ0:08 Æ0:02for the giants. Thus, our updated analysis of the [O i] k6300 line does not confirm the Hyades giant-dwarf oxygen discrepancy initially reported by King & Hiltgen, suggesting that the discrepancy was a consequence of analysis-related systematic errors. LTE oxygen abundances from the near-IR, high-excitation O i triplet are also derived for the giants, and the resulting abundances are approximately 0.28 dex higher than those derived from the [O i] line, in agreement with non-LTE predictions. Non-LTE corrections from the literature are applied to the giant triplet abundances; the resulting mean abundance is ½O/H¼þ0:17 Æ0:02, in decent concordance with the giant and dwarf [O i] abundances. Finally, Hyades giant and dwarf O abundances derived from the [O i] k6300 line and high-excitation triplet, as well as dwarf O abundances derived from the near-UV OH k3167 line, are compared, and a mean cluster O abundance of ½O/H¼þ0:12 Æ0:02 is achieved, which represents the best estimate of the Hyades O abundance

Eta model forecasts as input to crop models for the Mid-Southern region of Brazil

Este trabalho tem por objetivo avaliar a precipitação pluvial e as temperaturas máximas e mínimas previstas pelo Modelo Eta para até 120 dias de previsão em 24 localidades distribuídas na região Centro-Sul do Brasil. A avaliação se baseia na comparação de séries históricas de chuva e temperaturas de 1997 a 2002, com as previsões de 30, 60 e 120 dias de antecedência do Modelo Eta para as 24 localidades. Foram utilizados valores de média, mediana e desvio padrão nesta avaliação. Os resultados indicam que estas previsões geralmente subestimam as chuvas e a amplitude térmica nestas localidades. Os menores erros de precipitação pluvial se localizam mais destacadamente em Itumbiara e Rio Verde, enquanto que os maiores, em Porangatu e Manduri. Por outro lado, os menores erros de temperatura máxima se localizam destacadamente em Brasília, Manduri e Piracicaba, enquanto que os maiores ocorrem em Barreiras e Porangatu. Apesar de o modelo apresentar erros sistemáticos nas previsões de temperaturas, estes erros podem ser removidos para que os valores corrigidos possam ser introduzidos nos modelos de culturas.The objective of this study was to evaluate the 120-day precipitation and maximum and minimum temperature forecasts by Eta Model over 24 locations around the Mid-Southern of Brazil. The evaluation was based on comparing observed time series of precipitation and temperatures from 1997 to 2002 to 30, 60 and 120-day forecasts of Eta Model over these 24 locations. Mean, median and standard deviation were used in the evaluation. The results show that these forecasts generally underestimate rain and temperature range. The smallest precipitation errors occurred in Itumbiara and Rio Verde, whereas the largest errors occurred in Porangatu and Manduri. The smallest maximum temperature errors occurred in Brasília, Manduri and Piracicaba whereas the largest errors in Barreiras and Porangatu. Despite the systematic errors exhibited by the precipitation and temperature forecasts, these errors can be removed and the corrected values input into the crop models

Effectiveness of psychoeducational interventions for family carers of people

Psychoeducational interventions for family carers of people with psychosis are effective for improving compliance and preventing relapse. Whether carers benefit from these interventions has been little explored. This systematic review investigated the effectiveness of psychoeducation for improving carers' outcomes, and potential treatment moderators. We searched for randomised controlled trials (RCTs) published in English or Chinese in eight databases. Carers' outcomes included wellbeing, quality of life, global morbidities, burden, and expressed emotion. Thirty-two RCTs were included, examining 2858 carers. Intervention duration ranged from 4 to 52 weeks, and contact times ranged from 6 to 42 hours. At post intervention, findings were equivocal for carers' wellbeing (SMD 0.103, 95% CI − 0.186 to 0.392). Conversely, psychoeducation was superior in reducing carers' global morbidities (SMD − 0.230, 95% CI − 0.386 to − 0.075), perceived burden (SMD − 0.434, 95% CI − 0.567 to − 0.31), negative caregiving experiences (SMD − 0.210, 95% CI − 0.396 to − 0.025) and expressed emotion (SMD − 0.161, 95% CI − 0.367 to − 0.045). The lack of available data precluded meta-analysis of outcomes beyond short-term follow-up. Meta-regression revealed no significant associations between intervention modality, duration, or contact time and outcomes. Further research should focus on improving carers' outcomes in the longer-term and identifying factors to optimise intervention design

Augmented Reality in Astrophysics

Augmented Reality consists of merging live images with virtual layers of information. The rapid growth in the popularity of smartphones and tablets over recent years has provided a large base of potential users of Augmented Reality technology, and virtual layers of information can now be attached to a wide variety of physical objects. In this article, we explore the potential of Augmented Reality for astrophysical research with two distinct experiments: (1) Augmented Posters and (2) Augmented Articles. We demonstrate that the emerging technology of Augmented Reality can already be used and implemented without expert knowledge using currently available apps. Our experiments highlight the potential of Augmented Reality to improve the communication of scientific results in the field of astrophysics. We also present feedback gathered from the Australian astrophysics community that reveals evidence of some interest in this technology by astronomers who experimented with Augmented Posters. In addition, we discuss possible future trends for Augmented Reality applications in astrophysics, and explore the current limitations associated with the technology. This Augmented Article, the first of its kind, is designed to allow the reader to directly experiment with this technology.Comment: 15 pages, 11 figures. Accepted for publication in Ap&SS.
