Deer keds (Diptera: Hippoboscidae: Lipopteninae) are blood-feeding ectoparasitic flies that usually feed on deer and other Cervidae but sometimes bite humans. Two species are found in eastern North America: introduced European deer keds (Lipoptena cervi L.) and native Neotropical deer keds (L. mazamae Rondani). While historically dismissed as potential vectors of diseases, half a dozen tick-borne pathogens, including species pathogenic to humans, have been sequenced from deer keds over the last 15 years. In response to growing concerns that deer keds may transmit pathogens, efforts have been made recently to determine the distribution of deer keds in North America. Herein, we present new state records for Illinois, Kentucky, Michigan, and Nebraska, as well as 146 new county records from these and other states. We also discuss the relationship of hippoboscids to CO2-baited mosquito traps and review the impact of the community science platforms iNaturalist.org and BugGuide.net.

Denne artikkelen handler om barn som ble smittet med tuberkulose og innlagt på sanatorium i Oslo på 1940-, 1950- og 1960-tallet. Den bygger på 11 intervjuer der kvinner og menn fra ulike deler av landet forteller om det å få tuberkulose som barn og om å bli innlagt på sanatorium, enten Grefsen Barnesanatorium (8) eller Åkeberg Barnehjem (3). Barna var fra omkring 17 måneder og opp til 10 år ved innleggelse, og for barna varte oppholdet på sanatorium fra ett til tre år.

I denne artikkelen problematiseres bærekraftige barnehagepraksiser med materialer. Gjennom digitale fokusgrupper med barnehagelærere fra nettverket «Rommets kraft» utforsket jeg hvordan pedagogisk dokumentasjon kan bidra til at barnehagelærere øker sin kunnskap, eller får økt kunnskap, eller bidra til økt kunnskap hos barnehagelærere om bærekraftige perspektiver på rom og materialer. Begrepene kompost (Haraway, 2016) og response-ability (Barad, 2007; Haraway 2016) utforskes teoretisk og analytisk innenfor feministiske nymaterialistiske teorier. Bærekraftige barnehagepraksiser kan se ut til å stå i konflikt med barnehagens tradisjoner og kultur, ved bruk av juletre og gjenbruksmaterialer, og de yngste barnas interesse for små ting. Disse dilemmaene blir kompostert, og prosessen produserer dermed etiske og faglige utfordringer som barnehagelærerne berøres av i arbeid med bærekraft i barnehagen. ENGLISH ABSTRACT To Network Sustainability Practices. A Compost of Christmas Trees, Recycled Materials, and Small Materials This article problematizes sustainable Early Childhood Education and Care (ECEC) practices with materials. Through digital focus group discussions with ECEC teachers in the “The Power of Space” network, it explores how pedagogical documentation can contribute to increasing ECEC teachers’ knowledge of sustainable perspectives on space and materials. Theoretically and analytically, the concepts compost (Haraway, 2016) and response-ability from feminist new materialist theories are explored (Barad, 2007; Haraway, 2016). Sustainable kindergarten practices may appear to conflict with the ECEC’s practices in relation to traditions and culture, such as the use of Christmas trees, recycled materials, and the youngest children’s interest in small materials. These dilemmas are “composted,” and the process produces ethical and professional challenges that ECEC teachers must navigate in their work with sustainability practices in the ECEC.

As the exploration of marine resources continues to deepen, the utilization of Autonomous Underwater Vehicles (AUVs) for conducting marine resource surveys and underwater environmental mapping has become a common practice. In order to successfully accomplish exploration missions, AUVs require high-precision underwater navigation information as support. A Strapdown Inertial Navigation System (SINS) can provide AUVs with accurate attitude and heading information, while a Doppler Velocity Log (DVL) is capable of measuring the velocity vector of the AUVs. Therefore, the integrated SINS/DVL navigation system can furnish the necessary navigational information required by an AUV. In response to the issue of DVL being susceptible to external environmental interference, leading to reduced measurement accuracy, this paper proposes an end-to-end deep-learning approach to enhance the accuracy of DVL velocity vector measurements. The utilization of the raw measurement data from an Inertial Measurement Unit (IMU), which includes gyroscopes and accelerometers, to assist the DVL in velocity vector estimation and to refine it towards the Global Positioning System (GPS) velocity vector, compensates for the external environmental interference affecting the DVL, therefore enhancing the navigation accuracy. To evaluate the proposed method, we conducted lake experiments using SINS and DVL equipment, from which the collected data were organized into a dataset for training and assessing the model. The research results show that the DVL vector predicted by our model can achieve a maximum improvement of 69.26% in terms of root mean square error and a maximum improvement of 78.62% in terms of relative trajectory error.

O objetivo deste trabalho foi o de realizar uma análise de um acidente mortal com trator agrícola, identificado em relatório da Commission des Normes, de l'Équité, de la Santé et de la Sécurité du Travail (CNESST), por meio da Árvore das Causas e posterior elaboração de procedimento de boas práticas para o setor. O acidente de trabalho ocorreu na utilização do conjunto trator agrícola e carregador frontal, ao movimentar e transportar um grande fardo redondo de feno plastificado, em marcha-atrás, em superfície plana e na extremidade lateral da parcela, com declive. A aplicação do método apurou que as causas da morte do operador foram a não colocação do cinto de segurança e a porta da cabina do lado esquerdo estar apenas encostada, sem o trinco batido. Como não houve testemunhas do acidente, não foi possível saber a génese das causas que desencadearam toda a dinâmica do acidente e continuar a desenvolver a ramificação da árvore. Para o desfecho fatal contribuíram decisões e práticas de insegurança do operador, por falta de habilitação legal e de formação para operar o trator agrícola, bem como a ausência de procedimentos de segurança escritos e claros por parte da entidade empregadora, na utilização do trator agrícola com o carregador frontal.

Fiction involves exploring imaginative arrangements of places and characters: elements that can be recognized by readers. In childhood, exploration occurs from a safe home base of a caregiver; fiction enables a comparable basis. Physical elements in fiction are settings. More important are social explorations: transactions with characters that can include transformation. This is illustrated by Alice's Adventures in Wonderland.

The present study seeks to assess the impact of gestational hypertensive disorders on premature newborns below 34 weeks and to establish the main morbidities and mortality in the neonatal period and at 18 months. A retrospective observational study was carried out with 695 premature newborns of gestational age (GA) between 24 and 33 weeks and 6 days, born alive in the Neonatal ICU of Brasília's Mother and Child Hospital (HMIB), in the period from January 1, 2014, to July 31, 2019. In total, 308 infants were born to hypertensive mothers (G1) and 387 to normotensive mothers (G2). Twin pregnancies and diabetic patients with severe malformations were excluded. Outcomes during hospitalization and outcomes of interest were evaluated: respiratory distress syndrome (RDS), brain ultrasonography, diagnosis of bronchopulmonary dysplasia (BPD), diagnosis of necrotizing enterocolitis, retinopathy of prematurity, breastfeeding rate at discharge, survival at discharge and at 18 months of chronological age and relationship between weight and gestational age. Newborns with hypertensive mothers had significantly lower measurements of birth weight and head circumference. The G1 group had a higher risk small for gestational age (OR 2.4; CI 95% 1.6-3.6; p <0.00), as well as a greater risk of being born with a weight less than 850 g (OR 2.4; 95% CI 1.2-3.5; p <0.00). Newborns of mothers with hypertension presented more necrotizing enterocolitis (OR 2.0; CI 95% 1.1-3.7); however, resuscitation in the delivery room and the need to use surfactant did not differ between groups, nor did the length of stay on mechanical ventilation, or dependence on oxygen at 36 weeks of gestational age. Survival was better in newborns of normotensive mothers, and this was a protective factor against death (OR 0.7; 95% CI 0.5-0.9; p <0.01). In the follow-up clinic, survival at 18 months of chronological age was similar between groups, with rates of 95.3% and 92.1% among hypertensive and normotensive mothers, respectively. Exclusive breastfeeding at discharge was 73.4% in the group of hypertensive women and 77.3% in the group of normotensive mothers. There were no significant differences between groups. Among the analyzed outcomes, arterial hypertension during pregnancy can increase the risk of low weight, small babies for gestational age (SGA), deaths in the neonatal period and enterocolitis, with no differences in weight and survival at 18 months of chronological age. Arterial hypertension presents a high risk of prematurity in the neonatal period, with no difference at 18 months of age.
