Two-photon fluorescence lifetime imaging applied to the mixing of two non-isothermal sprays : temperature and mixing fraction measurements

Droplets temperature is a key parameter for the study of heat and mass transfers in many spray applications. Time correlated single photons counting (TCSPC) is applied to monitor the fluorescence decay and determine the droplet temperature in the mixing zone of two sprays which are injected with significantly different temperatures. For some well-chosen fluorescent dye, like rhodamine B (RhB), the

Seismic refraction survey to identify faults along a planned viaduct site in Constantine, Algeria: Application and comparison of tomography and generalized reciprocal method interpretations

The design and construction of large infrastructure projects require detailed information on subsurface geology and identification of potential risks. Geophysical investigations can provide important information for design and risk assessment provided that the optimal method and interpretation approach is adopted.This work presents results from seismic refraction surveys carried out along a planneThe design and construction of large infrastructure projects require detailed information on subsurface geology and identification of potential risks.

Cardiopulmonary Resuscitation and Defibrillator Use in Sports

Sudden cardiac arrest (SCA) in young athletes is rare, with an estimated incidence ranging from 0.1 to 2 per 100,000 per athlete year. The creation of SCA registries can help provide accurate data regarding incidence, treatment, and outcomes and help implement primary or secondary prevention strategies that could change the course of these events. Early cardiopulmonary resuscitation (CPR) and defi

Changes in the Urinary Sodium-to-Potassium Ratio Are Associated with Blood Pressure Change in Older Japanese Adults : A 7-Year Longitudinal Study

Studies on the association between sodium-to-potassium (Na/K) ratio changes and blood pressure (BP) changes among older adults are limited. This 7-year longitudinal study examined the association between Na/K ratio changes (evaluated using spot urine tests) and BP changes among older Japanese adults. Data were collected from 432 participants (mean age: 70.3±4.4; range: 65–84 years) in 2012 and 201

CO2 and CH4 exchanges between moist moss tundra and atmosphere on Kapp Linné, Svalbard

We measured CO2 and CH4 fluxes using chambers and eddy covariance (only CO2) from a moist moss tundra in Svalbard. The average net ecosystem exchange (NEE) during the summer (9 June–31 August) was negative (sink), with −0.139 ± 0.032 µmol m−2 s−1 corresponding to −11.8 g C m−2 for the whole summer. The cumulated NEE over the whole growing season (day no. 160 to 284) was −2.5 g C m−2. The CH4 flux

Easy cleanups or forbearing improvements : The effect of CEO tenure on successor's performance

Long CEO tenure can harm firm performance even after the CEO is replaced. We analyze this issue by conditioning post-turnover firm performance on the length of the preceding CEO's tenure. Identification comes from instrumenting sudden CEO deaths as an exogenous shock to tenure length. We find that when a successor takes over after a long-tenured CEO, operating performance and stock returns are sig

Neuroinflammation in Parkinson’s Disease and its Treatment Opportunities

Parkinson’s disease (PD) is a complex, chronic, and progressive neurodegenerative disease that is characterized by irreversible dopaminergic neuronal loss in the substantia nigra. Alpha-synuclein is normally a synaptic protein that plays a key role in PD due to pathological accumulation as oligomers or fibrils. Clustered alpha-synuclein binds to the Toll-like receptors and activates the microglia,

MASW Characterisation of Conditions at Planned highway Expansions, Denmark

There is an increasing demand for the application of geophysical methods in engineering projects like bridge construction, mining for building materials and road expansions. Geophysical methods offer reasonable resolution and in cost efficient results as compared with more traditional methods like drilling.

Innovative Geophysical Surveys for Contaminated Site Ground Condition Characterisation, Albertslund, Denmark

Contamination of groundwater resources from industrial sites are a prevalent issue worldwide. Characteristic of contaminated site investigations is small site scale and variability of ground conditions that necessitate extensive invasive methods. Invasive methods are costly and therefore pursuit of applicable less costly non-invasive methods to characterise the site and develop a robust ConceptualContamination of groundwater resources from industrial sites are a prevalent issue worldwide.

S-wave reflection profiling: Applicability and demonstrated use in Denmark at site and regional scale

Multi-component reflection methods have gained acceptance for near surface mapping during recent years. Two case studies from Denmark employing shear wave reflection at different survey scales are presented. The first case study is a small site scale investigation to image the near surface lithology of a contaminated site.

Bone mass in Saudi women aged 20–40 years : the association with obesity and vitamin D deficiency

Summary: This study describes that low bone density is prevalent in premenopausal Saudi women, especially women of normal weight and vitamin D deficiency. Although BMD is higher in obese young women, this may not be beneficial later in life in conjunction with persistent vitamin D deficiency. Introduction: Not attaining peak bone mass is one crucial factor contributing to the risk of developing os

Urban Geoelectrical Survey and Spatially Constrained Interpretation for a New Metro in Copenhagen

Geophysical methods are prone to fail in an urban environment as all sources of noise are present in cities. The Fælledparken Park, a large open space area in Copenhagen, Denmark is not an exception. However, an extension of the metro along sections of high variability on the surface of a limestone surface motivated the use of geoelectrics as complement to seismic methods.
