Incident Angle of Saltating Particles in Wind-Blown Sand
Incident angle of saltating particles plays a very important role in aeolian events. In this paper, the incident angles of sand particles near the sand bed were measured in wind tunnel. It reveals that the incident angles range widely from 0° to 180° and thereby the means of angles are larger than published data. Surprisingly, it is found the proportion that angles of 5°-15° occupy is far below...
متن کاملWhole grains and incident hypertension in men.
BACKGROUND Prospective data on the relation between whole grain intake and incident hypertension in men are limited, and no previous studies have quantitatively estimated total grams of whole grains in relation to risk of hypertension. OBJECTIVE The purpose of this study was to estimate the association of whole-grain intake (g/d) and risk of incident hypertension in a large prospective cohort...
متن کاملAntithrombotic medication and incident open-angle glaucoma.
PURPOSE To determine the associations between the use of antithrombotic drugs and incident open-angle glaucoma (OAG). METHODS Ophthalmic examinations including measurements of the IOP and perimetry were performed at baseline and follow-up in 3939 participants of the prospective population-based Rotterdam Study who did not have OAG at baseline. The use of antithrombotic drugs was monitored con...
متن کاملIncident open-angle glaucoma and intraocular pressure.
PURPOSE To evaluate the role of baseline intraocular pressure (b-IOP) as a risk factor for incident open-angle glaucoma (OAG) in participants of African origin from the Barbados Eye Studies. DESIGN Population-based 9-year cohort study. PARTICIPANTS Three thousand two hundred twenty-two persons examined during the study period who were free of glaucoma at baseline and at risk of developing O...
متن کاملIncident open-angle glaucoma and blood pressure.
BACKGROUND The risk of open-angle glaucoma (OAG) may be related to low blood pressure (BP) relative to intraocular pressure (IOP), ie, to low perfusion pressure (PP). Alternatively, systemic hypertension may increase OAG risk. OBJECTIVE To clarify these possible relationships by evaluating hypertension and PP (where PP = BP - IOP) as risk factors for incident OAG in a black population. DESI...
