Angle-resolved photoelectron spectrometry studies of the autoionization of the 2s22p 2P triply excited state of atomic lithium: experimental results and R-matrix calculations

We have measured the angle-resolved energy dependence of the electrons emitted over the energy range of the triply excited 2s22p2P lithium resonance using synchrotron radiation. We have also calculated the behavior of the angular distribution parameter β using the R-matrix approximation. Experimental and theoretical results are in good agreement and show deep minima in the 1s2p1,3P ionic channels. The energy at which the minima occur does not coincide with the resonance energy, but is shifted towards higher energy

Heat stress monitoring, modelling, and mitigation in a dairy cattle building in Reading, UK: impacts of current and projected heatwaves

Heat stress in dairy cattle buildings is a pressing challenge under global warming. While building climate resilience is as critical as improving animal thermal resilience, limited research has evaluated the effectiveness of building adaptations in specific spaces, such as cattle housing and milking parlours, particularly under extreme climate conditions. This study addresses this gap by assessing the impacts of observed and projected heatwaves on dairy housing and a milking parlour and possible mitigation solutions, through indoor heat stress measurements and dynamic livestock building thermal modelling. We advance the modelling capability by incorporating realistic sensible and latent heat dissipation from dairy cattle, accounting for body mass, daily milk production, and ambient temperatures. Measurements during the 2021 UK Heatwave revealed consistently higher indoor Temperature-Humidity Index (THI) levels compared to outdoors. The milking parlour experienced more severe heat stress (Level 3: Severe) than the housing (Level 2: Moderate) due to higher internal heat gains and poor ventilation, with notable differences between morning and afternoon milking times. Projections for the 2080s heatwave indicated that both spaces would experience heat stress day and night, with severity reaching Level 4 (Emergency) for most of the time. Under current heatwave conditions, solar reflective roof paint proved effective for the housing, while hybrid ventilation was effective for the milking parlour. However, these strategies were insufficient for future extreme heatwaves, emphasizing the need for advanced, tailored building adaptations. This study highlights the critical importance of designing climate-resilient dairy buildings to safeguard animal welfare and productivity in a warming world

A new measurement for posterior tilt predicts reoperation in undisplaced femoral neck fractures: 113 consecutive patients treated by internal fixation and followed for 1 year

Background and purpose Preoperative posterior tilt in undisplaced (Garden I–II) femoral neck fractures is thought to influence rates of reoperation. However, an exact method for its measurement has not yet been presented. We designed a new measurement for posterior tilt on preoperative lateral radiographs and investigated its association with later reoperation

Malunion after midshaft clavicle fractures in adults: The current view on clavicular malunion in the literature

This is an overview of the current literature on malunion after midshaft clavicle fracture. Anatomy, trauma mechanism, classification, incidence, symptoms, prevention, and treatment options are all discussed. The conclusion is that clavicle malunion is a distinct clinical entity that can be treated successfully

Utterance Duration as It Relates to Communicative Variables in Infant Vocal Development

Click on the DOI link to access the article (may not be free).Purpose: We aimed to provide novel information on utterance duration as it relates to vocal type, facial affect, gaze direction, and age in the prelinguistic/early linguistic infant. Method: Infant utterances were analyzed from longitudinal recordings of 15 infants at 8, 10, 12, 14, and 16 months of age. Utterance durations were measured and coded for vocal type (i.e., squeal, growl, raspberry, vowel, cry, laugh), facial affect (i.e., positive, negative, neutral), and gaze direction (i.e., to person, to mirror, or not directed). Results: Of the 18,236 utterances analyzed, durations were typically shortest at 14 months of age and longest at 16 months of age. Statistically significant changes were observed in utterance durations across age for all variables of interest. Conclusion: Despite variation in duration of infant utterances, developmental patterns were observed. For these infants, utterance durations appear to become more consolidated later in development, after the 1st year of life. Indeed, 12 months is often noted as the typical age of onset for 1st words and might possibly be a point in time when utterance durations begin to show patterns across communicative variables.Division of Research and Graduate Studies and the Department of Communication Sciences and Disorders at East Carolina University and from the Department of Communication Sciences and Disorders at Idaho State University
