Structural Performance-Based Design Optimisation of a Secondary Mirror for a Concentrated Solar Power (CSP) Plant
Concentrated Solar Power (CSP) plants use mirrors to reflect and concentrate sunlight onto a receiver, to heat a fluid and store thermal energy, at high temperature and energy density, to produce dispatchable heat and/or electricity. The secondary mirror is a critical component in the optical system of certain Solar Power Tower plants (SPT), as it redirects the concentrated sunlight from the primary mirror onto the receiver, which can be arranged at ground level. In this study, we propose a design optimisation for the secondary mirror of a CSP plant. The design optimisation method consists of two steps. The first step involves the use of the finite element simulation software Abaqus 2022 to analyse the structural performance of the secondary mirror under thermal loads and wind. The second step consists of the use of simulation results to identify the combination of design parameters and best performances, with respect to both design constraints and structural safety. This is carried out by developing an algorithm that selects those configurations which satisfy the constraints by using safety coefficients. The proposed optimisation method is applied to the design of a potential configuration of a secondary mirror for the beam-down of the CSP Magaldi STEM® technology, although the methodology can be extended to other components of CSP plants, such as primary mirrors and receivers, to further enhance the structural performance of these systems

Demographics, Support Opportunities, and Self-Reported Well-Being of Patients Presenting for Hepatitis C Treatment at a Federally Qualified Health Center in Philadelphia
Introduction: As the opioid epidemic develops and evolves, the number of people who inject drugs is rising. A growing number of new Hepatitis C Virus (HCV) infections have been identified in people who inject drugs.
Objective: This study aims to better understand the demographics, well-being, and satisfaction with medical care of patients presenting for HCV treatment at a Federally Qualified Health Center (FQHC) in an urban setting. The study also looks to assess the impact of continued connection to holistic medical care.
Methods: Surveys were administered to 51 unique patients at their first visit for HCV treatment. Along with demographic questions, the survey included the PHQ-9 depression screen, the PSQ-18 patient satisfaction questionnaire, the AUDIT-C alcohol screen, the SF-12 Health Survey, and an HCV risk factor assessment. Nineteen of the 51 patients were re-surveyed after 3 months.
Conclusion: Many of the patients presenting for HCV treatment face difficulties such as substance use, homelessness, low socioeconomic status, disability, unemployment, and a history of incarceration. HCV treatment offers opportunities to connect patients to a support system that addresses those problems. The patients surveyed, who had access to patient navigators, social workers, behavioral health counselors, and benefits coordinators, showed improvements in general health, mental health, and in satisfaction with their care. More data is needed to see if the results are generalizable to a broader population.
Cultivares de feijoeiro-comum para o Estado de Mato Grosso.
Os trabalhos de pesquisas envolvendo avaliação de genótipos de feijoeiro-comum vêm acontecendo há muitos anos, num esforço integrado entre a Empaer-MT e Embrapa Arroz e Feijão, o que têm contribuído para a recomendação de cultivares para o estado de Mato Grosso. Uma maneira de ampliar a área de cultivo e produção no Mato Grosso é disponibilizar aos agricultores cultivares que sejam mais adaptadas às diferentes condições climáticas do Estado. Sendo assim, com um maior conhecimento dessas regiões, foram conduzidos doze ensaios compostos por dezenove genótipos com grãos do tipo carioca, preto, rajado, jalo, roxinho e rosinha, nos anos 2008 e 2009, nas safras da seca e irrigada, visando também atender os cultivos na agricultura familiar, que estão localizados em regiões de baixas altitudes com temperaturas mais elevadas.CONAFE
A new and rare actinote hübner (Lepidoptera : Nymphalidae: Heliconiinae : Acraeini) from southeastern Brazil
The present paper describes a new species of Actinote (Nymphalidae, Heliconiinae, Acraeini), Actinote keithbrowni Freitas, Francini & Mielke sp. nov., from southeastern Brazil, based on morphological and molecular data. The new species is very similar in wing pattern to Actinote eberti, within what we term the “light-gray mimicry complex.” The host plants and immature stages of the new species are unknown. Actinote keithbrowni sp. nov. is one of the rarest species of Actinote from Brazil: in total, only eight individuals of this species are known from a narrow region of the Itatiaia massif despite years of collecting effort in that region since the 1940s495696703CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP303834/2015-3; 304639/2014-20012011/50225-3; 2013/50297-0; 2015/24663-4AVLF acknowledges support from Fundação de Amparo à Pesquisa do Estado de São Paulo – (FAPESP) (Biota-Fapesp grants 2011/50225-3, 2013/50297-0) and from the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) (303834/2015-3).

Uncovered diversity of a predominantly andean butterfly clade in the brazilian atlantic forest : a revision of the genus praepedaliodes forster (Lepidoptera: Nymphalidae, Satyrinae, Satyrini)
The genus Praepedaliodes Forster, 1964, the only representative of the mega-diverse mostly Andean Pedaliodes complex lineage in the Brazilian Atlantic Forest, is revised. Prior to this study, four species were known, P. phanias (Hewitson, 1862), P. granulata (Butler, 1868), P. amussis (Thieme, 1905) and P. exul (Thieme, 1905). Here, a further six are described, all from SE Brazil, expanding to 10 the number of species in this genus. Lectotypes are designated for P. phanias, P. granulata and P. amussis. The genus is most diverse in the Serra da Mantiqueira (São Paulo, Rio de Janeiro, Minas Gerais) and in the Serra Geral (Paraná, Santa Catarina) with seven species occurring in both ranges. Praepedaliodes phanias is the most widespread species and the only one found in the western part of the Atlantic Forest; only this species and P. duartei Dias, Dolibaina & Pyrcz n. sp. occurring to near sea level. Other species, P. zaccae Dolibaina, Dias & Pyrcz n. sp., P. francinii Freitas & Pyrcz n. sp., P. sequeirae Pyrcz, Dias & Dolbaina n. sp., P. landryi Pyrcz & Freitas n. sp. and P. pawlaki Pyrcz & Boyer n. sp. are strictly montane and the highest species richness is reached at 1400–1800 m. One species, P. sequeirae n. sp., is a narrow endemic found only at timberline in the Agulhas Negras massif above 2300 m. Immature stages are described for two species, P. phanias and P. landryi n. sp. Molecular data (barcode region of cytochrome oxidase, subunit I) and adult morphology, including male and female genitalia, support the genus as monophyletic, belonging to a predominantly Andean clade of the Pedaliodes Butler, 1867 complex. Morphological evidences, in particular female genitalia comparative analysis, indicate the genera Physcopedaliodes Forster, 1964 and Panyapedaliodes Forster, 1964 as possibly the closest relatives to Praepedaliodes. Molecular data are inconclusive in this respect472211255CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP302585/2011-7, 303834/2015-3; 563332/2010-7; 41143/2009-6; 150542/2013-5; 308247/2013-2; 304639/2014-1Não tem2016/15873-8; 2011/50225-3; 2013/50297-0We would like to express our gratitude the following persons who contributed at different stages in the elaboration of this paper: Alfred Moser (Porto Alegre), Ronaldo Francini (UNISANTOS) and André Tacioli, Junia Y.
