I would like to begin by thanking Ron Chrisley for his interesting and detailed commentary.1 There is much I find to agree with; indeed, it seems to me that his essay can largely be read, not as a criticism of the perspective offered in my own article,2 but rather as a useful and largely complementary alternate view. I am especially grateful for the insights expressed in the last section of the...

the present study was conducted to investigate the effects of ensiling pistachio by-product (pbp) on nutrient value, some physical and chemical parameters. fresh pbp was ensiled into a trench silo for three months and simultaneously amount of pbp was dried in front of the sun. chemical composition, buffering capacity, water holding capacity, protein fractionation according to cornell net carboh...

the aim of the present study was to evaluate the effects of sun-drying, ensiling and addition of polyethylene glycol (peg) on deactivation of tannins in the pistachio by-products hull (pbh). the chemical composition, protein quality and phenolic compounds of fresh pistachio by-products hull, sun-dried and ensiled for either 30 or 60 days were assessed. organic matter digestibility (omd) and met...

the objective of this study was to investigate the effects of saffron as a natural sunscreen and moisturizer. the pollens of the saffron were dried and powdered in a grinder. the experimental formulations included a homosalate (8%) lotion reference, lotions with 2, 4 and 8% of grinded saffron, and the control lotion base without saffron. the lotions containing saffron were prepared like homosal...

In vitro evaluation of sun protection activity of some medicinal herbs by SPF determination, to find out which herbal extracts have the best protection activity and can be used as sunscreen agent. Sun rays are the most environmental harmful factor which affect skin, cause sun burn and photo aging. According to the previous studies the plant’s flavonoids are suitable absorbents for UV rays. In t...

W hen Galileo turned his tele­ scope on the sun in 1610, he discovered that there were dark spots on the solar disk. Observing the motion of the spots across the disk, he deduced that the sun rotated once in about 27 days. One of his contempo­ raries, Christoph Scheiner, undertook a systematic program of observing the spots. From these observations Scheiner found that the rotation period of the...
