Abstract	When a force probe with a small liquid drop adhered to its tip makes contact with a substrate of interest, the normal force right after contact is called the snap-in force. This snap-in force is related to the advancing contact angle or the contact radius at the substrate. Measuring snap-in forces has been proposed as an alternative to measure the advancing contact angles of surfaces. The snap-in occurs when the distance between the probe surface and the substrate is h

Abstract	When a force probe with a small liquid drop adhered to its tip makes contact with a substrate of interest, the normal force right after contact is called the snap-in force. This snap-in force is related to the advancing contact angle or the contact radius at the substrate. Measuring snap-in forces has been proposed as an alternative to measure the advancing contact angles of surfaces. The snap-in occurs when the distance between the probe surface and the substrate is hS, which is amenable to geometry, assuming the drop was a spherical cap before snap-in. Equilibrium is reached at a distance hE < hS. At equilibrium, the normal force F = 0, and the capillary bridge is a spherical segment, amenable again to geometry. For a small normal displacement Δh = h – hE, the normal force can be approximated with F ≈ −k1Δh or F ≈ −k1Δh – k2Δh2, where k1 = −∂F/∂h and k2 = −1/2·∂2F/∂h2 are the effective linear and quadratic spring constants of the bridge, respectively. Analytical expressions for k1,2 are found using Kenmotsu’s parameterization. Fixed contact angle and fixed contact radius conditions give different forms of k1,2. The expressions for k1 found here are simpler, yet equivalent to the earlier derivation by Kusumaatmaja and Lipowsky (2010). Approximate snap-in forces are obtained by setting Δh = hS – hE. These approximate analytical snap-in forces agree with the experimental data from Liimatainen et al. (2017) and a numerical method based on solving the shape of the interface. In particular, the approximations are most accurate for super liquid-repellent surfaces. For such surfaces, readers may find this new analytical method more convenient than solving the shape of the interface numerically.

Abstract	In the context of circular economy and global shortage of phosphorus (P) fertilizer production, it is crucial to effectively recover P during the treatment and disposal of sewage sludge (SS). Although thermal treatment of SS has been widely applied, a targeted P reclamation route is not yet well established. This study has comprehensively investigated and compared the physicochemical properties of SS and solid residues (hydrochar (HC), biochar (BC), sewage sludge ash (SSA), hydrochar ash (HCA), and biochar ash (BCA)) after application of three typical thermal treatment techniques (i.e., hydrothermal carbonization (180‒240 °C), pyrolysis (400‒600 °C) and combustion (850 ℃). P speciation and transformation during thermal processes were extensively explored followed by a rational proposal of effective P reclamation routes. Specifically, thermal processing decomposed organic P and converted non-apatite P to apatite P. Orthophosphate-P was found to be the main species in all samples. Physicochemical properties of the resulting thermal-derived products were significantly affected by the thermal techniques applied, thereby determining their feasibility for different P reclamation purposes. In particular, ash is not recommended for agricultural use due to higher harmful metals content, while acid leaching can be an alternative solution to synthesize non-Fe-containing P products because of the lower co-dissolved Fe content in the leachate. HC and BC offer the option for synthesis of Fe containing products. Eventually, HC and BC demonstrate great potential for agriculture application, however, a comprehensive risk assessment should be conducted before their real-world applications.

Abstract	Congenital anomalies of the kidney and urinary tract (CAKUT) are common birth defects, which cause the majority of chronic kidney diseases in children. CAKUT covers a wide range of malformations that derive from deficiencies in embryonic kidney and lower urinary tract development, including renal aplasia, hypodysplasia, hypoplasia, ectopia, and different forms of ureter abnormalities. The majority of the genetic causes of CAKUT remain unknown. Research on mutant mice has identified multiple genes that critically regulate renal differentiation. The data generated from this research have served as an excellent resource to identify the genetic bases of human kidney defects and have led to significantly improved diagnostics. Furthermore, genetic data from human CAKUT studies have also revealed novel genes regulating kidney differentiation.

Abstract	Eye contact with a humanoid robot has been shown to evoke similar affect and affiliation related psychophysiological responses as eye contact with another human. In this pre-registered study, we investigated whether these effects are dependent on the experience of being "watched". Psychophysiological responses (SCR, zygomatic and corrugator facial EMG, frontal EEG asymmetry) to a humanoid robot's or a human model's direct vs. averted gaze were measured while manipulating the participants' belief of whether the robot/human model could see them or not. The results showed greater autonomic arousal responses and facial responses related to positive affect both to the robot's and the human model's direct vs. averted gaze, regardless of the belief condition. The belief condition influenced the overall magnitude of these responses to both stimulus models, however, to a lesser extent for the robot than for the human model. For the frontal EEG asymmetry, the effect of gaze direction was non-significant in both belief conditions. The results lend further support for the importance of eye contact in human-robot interaction and provide insights into people's implicit attributions of humanoid robots' mental capacities.

Abstract	LBGTQ+ students often miss the support and information they need in the school nursing, but little is known about junior high school (JHS) nurses' work with LGBTQ+ students. 15 JHS nurses were interviewed in focus groups about their perceptions of supporting LGBTQ+ students. Four interconnected themes were identified with inductive thematic analysis: (1) JHS nurses' professional identity and practice; (2) Recognition of sexual and gender diversity in school; (3) Family acceptance process; and (4) LGBTQ+ students as school nursing clients. JHS nurses self-identified as accepting professionals, but having limited skills, knowledge, and education needed in supporting LGBTQ+ students. Supporting LGBTQ+ students is a complex phenomenon, and to enhance JHS nurses' competence in providing care for these students, sexual and gender diversity needs to be included in evidence-based nursing information sources, covered in nursing education, and the school needs to be secured as LGBTQ+ safe place.

Abstract	Previous research has shown that eye contact, in human-human interaction, elicits increased affective and attention related psychophysiological responses. In the present study, we investigated whether eye contact with a humanoid robot would elicit these responses. Participants were facing a humanoid robot (NAO) or a human partner, both physically present and looking at or away from the participant. The results showed that both in human-robot and human-human condition, eye contact versus averted gaze elicited greater skin conductance responses indexing autonomic arousal, greater facial zygomatic muscle responses (and smaller corrugator responses) associated with positive affect, and greater heart deceleration responses indexing attention allocation. With regard to the skin conductance and zygomatic responses, the human model's gaze direction had a greater effect on the responses as compared to the robot's gaze direction. In conclusion, eye contact elicits automatic affective and attentional reactions both when shared with a humanoid robot and with another human.

Towards an AMR management plan for low resource livestock sectors

Abstract	Abstract Global policy for managing antimicrobial resistance (AMR) is underpinned by a standardised and coherent global framework for reducing antibiotic use in clinical health, veterinary health, and food production sectors. Within the framework, problematic antibiotic use (a significant driver of AMR) is treated as a knowledge deficit on the part of users and prescribers, which can be remedied by educating them to make better informed treatment decisions. This narrow approach to AMR management conceals the socioeconomic and material drivers of antibiotic decision-making, creating challenges for low resource regions that rely on antibiotic therapies to manage uncertainty and precarity. Thus, there is a need for a global AMR policy that acknowledges the diversity of sociomaterial arrangements and practices that antibiotics form part of, if their use is to be reduced without undermining productivity or the attainment of poverty reduction indicators. Drawing upon research of antibiotic use in West Africa’s livestock sector, this article analyses the interrelation of antibiotics, AMR action plans, and production management strategies in ecologies of livestock breeding practices. We apply the STS-influenced perspective of noncoherence to analyse how seemingly contradictory practices and institutional logics productively coalesce. We argue that observing noncoherent practices increases our understanding of antibiotic use in relation to local breeding conditions that are frequently not of the producers’ making, whilst drawing attention to context-specific possibilities for improving livestock management capacities and reducing reliance on antibiotic therapies in low-resource settings. The article concludes by calling for an AMR global policy that is more responsive to local specificity rather than enforcing universal standardisation.
