Vertical Illuminance Measurement for Clear Skies in Tehran

Ultraviolet Sky Radiance Distributions of Translucent Overcast Skies

The diffuse sky radiation component in the ultraviolet wavelengths is often at least 50% of the global irradiance under clear skies, and is the dominant component of ultraviolet global radiation under translucent overcast skies. The distribution of sky radiance was measured in a rural area and modeled for wavelength bands of ultraviolet-B (UVB, 280-320 nm) and ultraviolet-A (UVA, 320-400 nm). S...

Did unusually sunny skies help drive the record sea ice minimum of 2007 ?

[1] We conduct experiments with an ice-ocean model to answer the question whether and to what degree unusually clear skies during the summer of 2007 contributed to the record sea ice extent minimum in the Arctic Ocean during September of 2007. Anomalously high pressure over the Beaufort Sea during summer 2007 appears associated with a strong negative cloud anomaly. This anomaly is two standard ...

Bridging the ‘Two Cultures’ of Research and Service: Can Complexity Theory Help?; Comment on “Experience of Health Leadership in Partnering With University-Based Researchers in Canada – A Call to ‘Re-imagine’ Research”

This commentary addresses Bowen et al’s empirical study of perspectives of Canadian healthcare staff towards research and their call for multi-faceted action to improve misalignments in the system. This commentary argues that tensions and misalignments between research and service are inherent and can never be eradicated. Building on previous work by Lanham et al, I pro...

Pure neural Leprosy: A case report

Leprosy is a chronic infectious disease endemic in Iran that mainly involves skin and peripheral nerves. Leprosy has several clinical forms. One of them is “Pure neural leprosy”. The diagnosis of this form is delayed due to lack of clinical signs in other tissues and can lead to permanent deformity. I will discuss my experience for 20 years in the diagnosis and treatment of this form of leprosy...
