Non-alloy Mg anode for Ni-MH batteries: Multiple approaches towards a stable cycling performance
No full textMg attracts much research interest as anode material for Ni-MH batteries thanks to its lightweight, cost-effectiveness and high theoretical capacity (2200 mA h g−1). However, its practical application is tremendously challenged by the poor hydrogen sorption kinetics, passivation from aggressive aqueous electrolytes, and insulating nature of MgH2. Mg-based alloys exhibit enhanced hydrogen sorption kinetics and electrical conductivity, but significant amount of costly transition metal elements are required. In this work, we have, for the first time, utilized non-alloyed but catalyzed Mg as anode for Ni-MH batteries. 5 mol.% TiF3 was added to nanosized Mg for accelerating the hydrogen sorption kinetics. Several strategies for preventing the problematic passivation of Mg have been studied, including protective encapsulation of the electrode and utilizing room-temperature/high-temperature ionic liquids and an alkaline polymer membrane as working electrolyte. Promising electrochemical performance has been achieved in this Mg–TiF3 composite anode based Ni-MH batteries with room for further improvements.</p
Assessing risk of self-harm in acute paediatric settings: A multicentre exploratory evaluation of the CYP-MH SAPhE instrument
No full textOBJECTIVE: To psychometrically assess the Children and Young People-Mental Health Self-harm Assessment in Paediatric healthcare Environments (CYP-MH SAPhE) instrument for the identification of immediate risk of self-harm in CYP, aged 10-19 years, in acute paediatric wards or emergency departments., DESIGN: The CYP-MH SAPhE Instrument was developed through a robust scoping review and Delphi consensus with 30 clinicians/topic experts. To evaluate the psychometric properties, a multicentre exploratory study was conducted., SETTING: Three acute hospitals in the UK., PARTICIPANTS: 163 CYP presenting at acute hospital settings with primary mental health (cases) or physical health (non-cases) conditions., PRIMARY AND SECONDARY OUTCOME MEASURES: Psychometric properties of the CYP-MH SAPhE instrument were evaluated through Principle Axis Factoring (PAF) with Oblimin (Kaiser normalisation) alongside measures of internal consistency (Cronbach's alpha), convergent, discriminant and face validity., RESULTS: PAF of the dichotomous items (n=9) loaded onto three factors (1) behaviours and intentions; (2) suicidality and (3) self-harm. Factors 1 (Cronbach's alpha=0.960) and 3 (Cronbach's alpha=1) had high internal consistency. There was: good level of agreement between raters (kappa=0.65); a moderately positive correlation between the CYP-MH SAPhE instrument and the Columbia-Suicide Severity Rating Scale; and discrimination between cases and non-cases across the three factors (factor 1: m=88 vs 70; factor 2: m=102 vs 70; factor 3: m=104 vs 68). Assessment of face validity resulted in six items being removed, culminating in an eight question, rapid assessment instrument., CONCLUSIONS: The results support the CYP-MH SAPhE Tool as a potentially reliable and valid instrument to identify immediate risk of self-harm in CYP presenting to acute paediatric healthcare environments, which is a burgeoning and significant global health issue.

Capacitance-based sensor for monitoring bees passing through a tunnel
No full textA sensor has been developed to monitor objects passing through tunnels using a capacitance bridge. While the sensor concept is easily adaptable to a wide range of objects or organisms which pass through an enclosed area, our version of the sensor was designed specifically for monitoring bumblebee colonies. Other bee sensors have been developed based on optical methods of detection. The capacitance sensor provides all the information of the optical sensors and additional information on the bee size and velocity. The sensor is expected to provide entomologists with more efficient methods of studying the foraging activities of bees.PT: J; CR: BRITTAIN WH, 1933, CAN DEP AGR B, V162, P119 BROMENSHENK J, 2005, 6910941, US BUCKLEY GA, 1978, BRIT J PHARMACOL, V64, P475 DEVILLERS J, 2004, COMPUT ELECTRON AGR, V42, P87 ELTZ T, 2001, P M EUR SECT IUSSI B FABERGE AC, 1943, J SCI INSTRUM, V20, P28 GREENBERG B, 1981, ENVIRON ENTOMOL, V10, P600 JARIMOPAS B, 2005, POSTHARVEST BIOL TEC, V35, P25 LIU C, 1990, J APICULT RES, V29, P20 MORANDIN LA, 2001, CAN ENTOMOL, V133, P883 MORANDIN LA, 2001, J ECON ENTOMOL, V94, P462 PHAMDELEGUE MH, 2002, APIDOLOGIE, V33, P425 STRUYE MH, 7 INT S ICPBR BEE PR, P269 STRUYE MH, 1991, P EXP APPL ENT AMST, V2, P150 STRUYE MH, 1994, APIDOLOGIE, V25, P384 TAPP HS, 2003, SENSOR ACTUAT B-CHEM, V92, P17; NR: 16; TC: 0; J9: MEAS SCI TECHNOL; PG: 8; GA: 994MISource type: Electronic(1

Systematic resolution study of [tau][tau] decays at Compact Muon Solenoid at the Large Hadron Collider
No full textThesis (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, 2011.In title on title page, "[tau][tau]" appear as lower case Greek letters. Cataloged from PDF version of thesis.Includes bibliographical references (p. 47).In this thesis, I perform a systematic resolution study for di-tau pairs at the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at CERN. I performed this analysis using Monte Carlo simulated events with a Higgs boson which decays into two tau particles with initial mass mH = 90 - 500 GeV/c ² . The two daughter taus were required to then decay leptonically. I determined the dependence of the input mass on the mass resolution and total energy contribution of the electron/muon visible mass peak. For mH 120 GeV/c², a mass resolution of =/ 50% can be achieved.by Ryan Howard Foote.S.B

Wildfire burn severity and post-wildfire time impact mechanical and hydraulic properties of forest soils
No full textVegetation contributes to the overall slope stability and is recognized as an environmentally friendly nature-based solution. Wildfires burn and denude vegetated slopes, thus increasing the risk of shallow landslides and debris flows. However, little attention has been given to assessing the effects of burn severity and the time elapsed since a wildfire on the hydro-geomechanical properties of burned slopes. This study performed a series of standard laboratory tests to evaluate the shear strength and saturated hydraulic conductivity (k(sat)) of forest soils collected from moderate-low (ML) burned, moderate-high (MH) burned, and unburned (UB) test plots. The plots were sampled one, four, and six months after the March 2022 wildfire in Uljin County, South Korea. The results show that the continuous deterioration of roots highly depended on the burn severity. The root biomass of ML- and MH-burned soils was consistently lower than those of the UB soils. The root deterioration reduced the shear strength of the soils temporally. The burned soil's cohesion intercept was 1.80-2.30 times lower than that of the UB soil six months post-wildfire, with the friction angle unaffected. One- and four-months post-wildfire, k(sat) of the burned soils was 1.22-3.15 times lower than the UB soil. Such lowered k(sat) was due to the fine ash-clogged pores and hydrophobic layers beneath the soil surface. However, six months post-wildfire, the burned soils' k(sat) increased by approximately twice that of the pre-wildfire condition because of macropore flow passages formed by impoverished roots. The appreciation of sand fraction, depreciation of fines content, and weakening of hydrophobicity over time have also emphasized their role in the temporal shifts in the properties of the ML- and MH-burned soils. The documented results herein can be incorporated into rainfall infiltration and stability analyses of wildfire-affected slopes, landslide susceptibility mapping, and mitigation measures design.
