The effect of space charge produced by corona at ground level on lightning attachment to high objects
submitted by blaigriinarongi 28 minutes ago - Topic: Geography
The influence of the corona space charge layer created at ground level on lightning attachment to high (20–100m) slender objects is numerically studied. The shielding effect of corona space charge produced near the object tip on the electric field at ground level is considered. The behavior of a non-stationary streamer-free corona developed from ground irregularities in a time-varying thunder...



A study of aerosol activation at the cloud edge with high resolution numerical simulations
submitted by blaigriinarongi 28 minutes ago - Topic: Geography
High resolution numerical simulations are used to study the structure of the cloud edge area. We consider an aerosol distribution function with a similar aerosol core size (12nm). The aerosol composition is assumed to be water soluble NaCl. Depending on the specific conditions in the investigated cloud edge area, water is evaporated or activated from the aerosol surface. We use a publicly avail...

Use of 2D-video disdrometer to derive mean density–size and Ze–SR relations: Four snow cases from the light precipitation validation experiment
submitted by blaigriinarongi 28 minutes ago - Topic: Geography
The application of the 2D-video disdrometer to measure fall speed and snow size distribution and to derive liquid equivalent snow rate, mean density–size and reflectivity–snow rate power law is described. Inversion of the methodology proposed by Böhm provides the pathway to use measured fall speed, area ratio and ‘3D’ size measurement to estimate the mass of each particle. Four snow ca...

Acquired hemophilia A and von Willebrand syndrome in a patient with late-onset systemic lupus erythematosus
submitted by 8miladiis 32 minutes ago - Topic: Health
Acquired hemophilia A (AHA) and acquired von Willebrand Syndrome (AVWS) are both rare bleeding disorders that can be associated with lymphoproliferative or autoimmune diseases. AHA is uniformly caused by inhibitory autoantibodies against coagulation factor VIII (FVIII), while the pathophysiology of AVWS comprises several distinct mechanisms, including reduced synthesis, accelerated clearance, o...

Hospitalization for Dupuytren's disease: A French national descriptive analysis, 2002 to 2009
submitted by lesdo 35 minutes ago - Topic: Health
The goal of this study is to describe hospitalization for treatment of Dupuytren's disease in France between 2002 and 2009. A repeated, annual, cross-sectional national survey of public and private French hospitals was performed between 2002 and 2009, with planned selection criteria for data extraction. Outcomes were age, sex, number of hospitalizations, length of stays, and types of surgical p...



Minimally invasive medial hip approach
submitted by lesdo 35 minutes ago - Topic: Health
The medial approach to the hip via the adductors, as described by Ludloff or Ferguson, provides restricted visualization and incurs a risk of neurovascular lesion. We describe a minimally invasive medial hip approach providing broader exposure of extra- and intra-articular elements in a space free of neurovascular structures. With the lower limb in a “frog-leg” position, the skin incision f...

The role of total elbow arthroplasty in traumatology
submitted by lesdo 35 minutes ago - Topic: Health
Fractures of the distal humerus account for 5% of osteoporotic fractures in subjects older than 60 years. A history of osteoporosis, co-morbidities, and joint comminution make their management difficult. The therapeutic options are limited to functional treatments, osteosynthesis, or either partial or total arthroplasty. Functional treatment of distal humerus fractures in the elderly subject pr...


Socio-economic and demographic determinants of under-five mortality in rural northern Ghana
submitted by rhstaathaff 36 minutes ago - Topic: Health
In spite of global decline in under-five mortality, the goal of achieving MDG 4 still remains largely unattained in low and middle income countries as the year 2015 closes-in. To accelerate the pace of mortality decline, proven interventions with high impact need to be implemented to help achieve the goal of drastically reducing childhood mortality. This paper explores the association between s...

Universal cures for idiosyncratic illnesses: A genealogy of therapeutic reasoning in the mental health field
submitted by rochde0 36 minutes ago - Topic: Health
Over the past decades, there has been a significant increase in prescriptions of psychotropic drugs for mental disorders. So far, most of the explanations of the phenomenon have focused on the process of medicalization, but little attention has been cast towards physicians’ day-to-day clinical reasoning, and the way it affects therapeutic decision-making. This article addresses the comple...


Education as networking: Rethinking the success of the harm reduction policy of Taiwan
submitted by rochde0 36 minutes ago - Topic: Health
The harm reduction policy of Taiwan has been considered a success. However, the HIV incidence among injection drug users declined before the nationwide needle and syringe program and drug substitution treatments were implemented. Thus, other factors in the policy might have contributed to its success. Some authors have suggested that education may have played a pivotal part. In this research, t...

The role of assessment packages for diagnostic consultations: A conversation analytic perspective
submitted by rochde0 36 minutes ago - Topic: Health
This article reports a conversation analysis of assessment package consultations. Healthcare delivery packages belong to a highly structured mode of healthcare delivery, in which specific courses of healthcare interventions related to assessment and treatment are predefined, both as to timing and content. Assessment packages are widely used in an increasing number of medical specialities; howev...


Benazepril affects integrin-linked kinase and smooth muscle alpha-actin expression in diabetic rat glomerulus and cultured mesangial cells
submitted by sodighepaar 37 minutes ago - Topic: Health
Diabetic nephropathy (DN) is the leading cause of chronic kidney disease and is associated with excessive cardiovascular morbidity and mortality. The angiotensin converting enzyme inhibitor (ACEI) benazepril has been shown to slow the progression of chronic renal disease and have beneficial effects in patients with a combination of chronic renal disease and cardiovascular disease. Transforming ...

New Record of Everglades Mink in Everglades National Park from the Stomach of an American Alligator
submitted by 2001harsi 42 minutes ago - Topic: Biology
Species management and conservation strategies require accurate information about species distributions and behaviors. Neovison vison evergladensis (Everglades Mink) is listed in Florida as threatened, yet its current population status and distribution are unknown. We report the first incontrovertible evidence of the occurrence of Everglades Mink in Everglades National Park (ENP) in 15 years. S...

Factor Structure and Gender Stability in the Multidimensional Condom Attitudes Scale
submitted by evanni 46 minutes ago - Topic: Health
Sexually transmitted infections continue to trouble the United States and can be attenuated through increased condom use. Attitudes about condoms are an important multidimensional factor that can affect sexual health choices and have been successfully measured using the Multidimensional Condom Attitudes Scale (MCAS). Such attitudes have the potential to vary between men and women, yet little wo...

Detection of a distinct variation site for geographical classification of mitochondrial DNA haplogroup A in the domestic goat (Capra hircus)
submitted by killynnaram 47 minutes ago - Topic: Biology
Domestic goats (Capra hircus) are classified into six different mitochondrial DNA (mtDNA) haplogroups (A, B, C, D, F, and G), of which haplogroup A shows worldwide distribution. However, there is currently no key for genetic and geographic classification of haplogroup A. In this study, we determined the complete sequences of the mtDNA control region from Korean native goat breeds. In addition, ...
