Impacts of increasing aridity and wildfires on aerosol loading in the intermountain Western US

Feedbacks between climate warming, land surface aridity, and wildfire-derived aerosols represent a large source of uncertainty in future climate predictions. Here, long-term observations of aerosol optical depth, surface level aerosol loading, fire-area burned, and hydrologic simulations are used to show that regional-scale increases in aridity and resulting wildfires have significantly increased

Climatology of new particle formation and corresponding precursors at storm peak laboratory

Thirteen years of measurements of ultrafine (3-10 nm diameter) aerosols are presented from a remote high elevation (3210 m a.s.l.) site in Colorado, Storm Peak Laboratory. Previous work has shown that frequent new particle formation (NPF) occurs regularly at the site (52% of days). This long-term climatology of ultrafine aerosols clearly shows a seasonal dependence on new particle formation at Sto

Contributions of dust and biomass burning to aerosols at a Colorado mountain-top site

Visible Multifilter Rotating Shadowband Radiometer (vis-MFRSR) data were collected at Storm Peak Laboratory (SPL), a mountain-top facility in northwest Colorado, from 1999 to 2011 and in 2013. From 2011 to 2014, in situ measurements of aerosol light scattering were also obtained. Using these data sets together, the seasonal impact of dust and biomass burning is considered for the western USA. Anal

With increasing age at tumor diagnosis in familial cancer: Cancer is limited to fewer organs

Hereditary cancer that has monogenic inheritance affects every tenth patient, on average, who is diagnosed with cancer, and it has been suggested, based on twin studies, that approximately 30% of all cancer patients have a genetic predisposition to developing cancer. In this article, the author posited that familial syndromes become more organ specific with increasing age at tumor presentation to

Online Optimisation of the MAX IV 3 GeV Ring Dynamic Aperture

In order to improve the resilience of the MAX IV 3 GeV ring's beam to a horizontal dipole kick while at the design tunes (42.20, 16.28) the optimisation algorithm RCDS (Robust Conjugate Direction Search) was deployed. The algorithm was able to increase the horizontal acceptance by finding new settings for the sextupole and octupole magnets, whilst leaving the vertical acceptance virtually unchangeIn order to improve the resilience of the MAX IV 3 GeVring’s beam to a horizontal dipole kick while at the designtunes (42.20, 16.28) the optimisation algorithm RCDS (Robust Conjugate Direction Search) was deployed.

Pulse-Picking by Resonant Excitation (PPRE) for Timing Users at the MAX IV 3 GeV Storage Ring

At synchrotron light storage rings there is demand for serving both high-brilliance and timing users simultaneously. At many rings this is commonly achieved by operating fill patterns with gaps of sufficient length, but this is not favorable for rings that operate with passive harmonic cavities to damp instabilities and increase Touschek lifetime by lengthening the bunches. For such rings, gaps in

Lack of Ability to Present Antigens on Major Histocompatibility Complex Class II Molecules Aggravates Atherosclerosis in ApoE-/- Mice

BACKGROUND: Hypercholesterolemic mice lacking factors required for activation of CD4+ T cells are characterized by reduced development of atherosclerosis. Consequently, it has been assumed that atherosclerosis involves loss of tolerance against modified self-antigens generated in response to hypercholesterolemia and that presentation of such antigens on major histocompatibility complex class II (M

Spirituality among Iranian nursing students during undergraduate study

Background Nursing students are expected to deliver holistic care in their upcoming career. Developing spirituality during nursing training is poorly understood. Objectives The current study aimed to explore the process of developing spirituality among Iranian nursing undergraduates. Patients and Methods The study employed Grounded theory approach and purposive sampling with maximum variation to s
