symbols are not loaded with intuitive interpretations. While it is true that a ) c is not an "-consequence of , since it is not probabilistically sound, both falsifying models of a ) c, must either falsify a ) b or b ) c; on the other hand, a ) c has a verifying model, a ^ b ^ c, which does not falsify either; this explains why a) c is an ME-consequence of (for any strength assignment). What th...

Background: The aim of this study was evaluation of developmental rate and Bax, Bcl-2 and ErbB4 genes expression following re-vitrification in compact and early blastocysts stages. Materials and Methods: 5-8 cell embryos were collected from female mature mice, 60-62 hours post hCG injection. The embryos were divided to five groups including: fresh, vitrified at 5-8 cells, vitrified at blastocys...

The neighborhood has had a long history in Iranian urbanization. Since urban plans wereintroduced by the authorities to shape urban development in Iran half a century ago, the concept of Iranian traditional neighborhood has been neglected gradually. The concept of neighborhood has not found the appropriate status in urban design and planning yet. One of the main reasons is that academics, profe...

stress is one of the main neuroscientific issues of our time. however, we have little knowledge of the neurological processes of stress. during the past decade studies have shown that in addition to the genetic factors, stress palys a major role in mental and psychosomatic diseases. severe, chronic and uncontrolled stresses cause some changes in monoaminergic system, and through neural peptides...

wound healing in the skin depends upon the availability of appropriate trace metals as enzyme cofactors and structural components in tissue repair. the present study is a part of a series of experimental investigations to examine the influence of bentonite on skin wound healing. surgically induced skin wounds in 48 young adult male rats were exposed topically to bentonite (12 round wound and 12...

Proxy Re-Encryption (PRE) allows a ciphertext encrypted under Alice’s public key to be transformed to an encryption under Bob’s public key without revealing either the plaintext or the decryption keys. PRE schemes have clear applications to cryptographic access control by allowing outsourced data to be selectively shared to users via re-encryption to appropriate keys. One concern for this appli...

Evaluation of the efficacy of screening programs involves the comparison of morbidity or mortality rates between screened and unscreened populations. Such comparisons are made most convincingly by means of experiments (1, 2), exemplified by the study of screening for breast cancer carried out by the Health Insurance Plan of Greater New York (HIP) (3). However, there are serious practical diffic...

The aim of this study is to describe a model of the dynamics of constituting a living place that is peculiar to the material condition of humanity today and that lends itself to empirical studies of metadevelopment and sustainability of the human-made environment. The empirical point of departure is the novel character of contemporary knowledge and knowing and the shift it leads to from the tra...
