in modern pharmacological medicine, saffron is used for various purposes due to its antioxidant effect. this study evaluated retinal function after treatment with saffron supplementation during a follow-up period of 6 months to provide further insight into the efficacy and safety considerations of this treatment. sixty patients with wet or dry age-related macular degeneration (amd) were randoml...

Transcellular placental maternofetal flux of calcium and magnesium is reduced in diabetic pregnancy in the rat which might be due to changes in placental cellularity. In order to investigate this wet and dry weight, DNA and protein content were measured in placentas from untreated diabetic (D(O)), insulin-treated diabetic (D(I)) and control rats (C) on day 21 of gestation (term=23 days). Wet an...

graduate school to study biology. At first, it was as if I was starting over, taking classes I had bypassed as an undergraduate, such as Introductory Organic Chemistry. But my motivation to master a new field made the experience enjoyable rather than frustrating. Moreover, I was captivated by the science. In my biology classes, I felt I was being offered gold nuggets of information that earlier...

Superhydrophobic surfaces let water droplets roll off with low friction and falling droplets rebound, leaving the surfaces completely dry. Such extremely water repellent surfaces are found in nature on lotus leaves, the legs of water striders and feather coatings of birds, and portray a beautiful example of ingenious biological design. They provide an exciting research avenue for physicists and...

Most studies on granular physics have focused on dry granular media, with no liquids between the grains. However, in geology and many real world applications (e.g., food processing, pharmaceuticals, ceramics, civil engineering, constructions, and many industrial applications), liquid is present between the grains. This produces inter-grain cohesion and drastically modifies the mechanical proper...

In the past a poor quality residue was frequently excused and accepted when incoming refuse had a high moisture content. This is no longer permissable. Means of coping with the wet refuse problem are summarized, based on reports from operators of IS municipal incinerators of various types, sizes and ages. The author's comments and conclusions are included.

The appearance of many natural materials is largely influenced by the environment in which they are situated. Capturing the effects of such environmental factors is essential for producing realistic synthetic images. In this work, we model the changes of appearance due to one such environmental factor, the presence of water or other liquids. Wet materials can look darker, brighter, or more spec...
