Large Sample Neutron Activation Analysis (LSNAA) was applied to perform non-destructive elemental analysis of a ceramic vase. Appropriate neutron self-shielding and gamma ray detection efficiency calibration factors were derived using Monte Carlo code MCNP5. The results of LSNAA were compared against Instrumental Neutron Activation Analysis (INAA) results and a satisfactory agreement between th...

Abstract This is an introduction to and translation of the Vase Deathless Ones’ Ambrosia Tantra . The presents itself as a treasure text that was taught by Padmasambhava in eighth-century Tibet finally revealed five hundred years later. In opening chapter, explains devastating epidemic disease will spread ultimately kill three out every four people world. Despite this dire prognosis, he also me...

Recently it has been claimed that some early Renaissance painters used concave mirrors to project real inverted images onto their supports (paper, canvas, oak panel, ...) which they then traced or painted over, and that this was a key source of an apparent increase in naturalism and realism in European painting around 1420. This bold theory makes implicit and explicit assumptions about the illu...

Indeterminate art, in which familiar objects are only suggestive, invokes a perceptual conundrum as apparently detailed and vivid images resist identification. We hypothesized that compared with paintings that depict meaningful content, object recognition in indeterminate images would be delayed, and tested whether aesthetic affect depends on meaningful content. Subjects performed object recogn...

This study examined the effect of inaccurate perspective on the impression of paintings by means of the protocol analysis of observers’ free talking. Participants observed two paintings by renowned artists used as stimuli in two conditions, either simultaneously (Exp.1) or with 1-week interval (Exp.2). In the original condition, they were presented in their original form drawn in inaccurate per...

We used event-related fMRI to investigate whether recollection- and familiarity-based memory judgments are modulated by the degree of visual similarity between old and new art paintings. Subjects performed a flower detection task, followed by a Remember/Know/New surprise memory test. The old paintings were randomly presented with new paintings, which were either visually similar or visually dif...

In the present study, we examined the eye movement behaviour of children and adults looking at five Van Gogh paintings in the Van Gogh Museum, Amsterdam. The goal of the study was to determine the role of top-down and bottom-up attentional processes in the first stages of participants' aesthetic experience. Bottom-up processes were quantified by determining a salience map for each painting. Top...

the effects of salicylic acid (sa) and putrescine (put), on cut narcissus was studied. sa (0, 100 and 200 mg l-1) and put (0, 150 and 300 mg l-1), their combinations were tested as preservative mixture. this study was conducted in a factorial experiment with complete randomized design on 108 narcissus cut flowers in horticulture laboratory of agriculture faculty of islamic azad university, jiro...
