One hundred seventy geotechnical boreholes, two geo-seismic profiles of multichannel analyses surface waves (MASW), and geoelectrical cross-sections electrical resistivity tomography (ERT) were carried out in the historical Diriyah urban zone. The borehole samples analyzed for parameters standard penetration test (SPT N-value), rock quality designation (RQD), compressive strength (CS). Moreover...

BACKGROUND Skin prick/puncture testing (SPT) is widely accepted as a safe, dependable, convenient, and cost-effective procedure to detect allergen-specific IgE sensitivity. It is, however, prone to influence by a variety of factors that may significantly alter test outcomes, affect the accuracy of diagnosis, and the effectiveness of subsequent immunotherapy regimens. Proficiency in SPT administ...

Background: Skin prick/puncture testing (SPT) is widely accepted as a safe, dependable, convenient, and cost-effective procedure to detect allergen-specific IgE sensitivity. It is, however, prone to influence by a variety of factors that may significantly alter test outcomes, affect the accuracy of diagnosis, and the effectiveness of subsequent immunotherapy regimens.

BACKGROUND Skin prick test (SPT) is a common test for diagnosing immunoglobulin E-mediated allergies. In clinical routine, technicalities, human errors or patient-related biases, occasionally results in suboptimal diagnosis of sensitization. OBJECTIVE Although not previously assessed qualitatively, lancet weight is hypothesized to be important when performing SPT to minimize the frequency of ...

BACKGROUND There is an increasing need to develop test instruments that make oral food challenges superfluous. OBJECTIVE We sought to study the utility of atopy patch tests (APTs) in the diagnostic workup of food allergy. METHODS We investigated 437 children (median age, 13 months; 90% with atopic dermatitis) referred for evaluation of suspected food allergy. Specific serum IgE (sIgE) measu...

We study the lags with which new technologies are adopted across countries, and their penetration rates once they are adopted. Using data from the last two centuries, we estimate both the extensive and the intensive margins of technology adoption. We document two new facts: there has been convergence in adoption lags between rich and poor countries, while there has been divergence in penetratio...

Pentesting is becoming an important activity even for smaller companies. One of the most important economic pressures is the cost of such tests. In order to automate pentests, tools such as Metasploit can be used. Post-exploitation activities can, however, not be automated easily. Our contribution is to extend Meterpreter-scripts so that postexploitation can be scripted. Moreover, using a multi...

BACKGROUND Peanut allergenicity has been reported to be influenced by heat treatment, yet the commonly available extracts for skin prick testing (SPT) are derived from raw extracts. OBJECTIVE To assess the effect of heat treatment on the SPT reactivity and specific IgE binding to peanut. METHODS Three commercial extracts and 3 laboratory-prepared extracts, including raw, roasted, and boiled...

When connected in small amounts, the impact of distributed generation (DG) on distribution system stability will be negligible. However, if its penetration level becomes higher, distributed generation may start to influence the dynamic behavior of the system as a whole. This paper presents a mathematical representation of a solid oxide fuel cell plant that is suitable for use in distribution sy...
