The production of fission products during reactor operation has a very important effect on reactor reactivity .Results of neutron cross section evaluations are presented for the main product nuclides considered as being the most important for reactor calculation and burn-up consideration . Data from the main international libraries considered as containing the most up-to-date nuclear data and the latest experimental measurements are considered in the evaluation processes, we describe the evaluated cross sections of the fission product nuclides by making inter comparison of the data and point out the discrepancies among libraries.
The messages are ancient method to exchange information between peoples. It had many ways to send it with some security.
Encryption and steganography was oldest ways to message security, but there are still many problems in key generation, key distribution, suitable cover image and others. In this paper we present proposed algorithm to exchange security message without any encryption, or image as cover to hidden. Our proposed algorithm depends on two copies of the same collection images set (CIS), one in sender side and other in receiver side which always exchange message between them.
To send any message text the sender converts message to ASCII c

A brief description of the parasites along with some notes on their infection rate, prevalence and discussion with the pertinent literature are provided.
Amygdalin specifically represents the apricot (Prunus armeniaca) seed in the Rosacea family of plants. Except for cyanogenic glycoside, the seeds include a variety of substances, including trace minerals, vitamins, carbohydrates, organic acids, esters, phenols, and terpenoids. It is well known that bioregulators have the ability to control the activity of certain hormones and enzymes. The current study examined the effect of Iraqi apricot seed extract on physiological parameters in male rats, including blood parameters, hormone parameters, and antioxidant parameters, as well as histological studies of the spleen and testes. The study comprised four groups, each consisting of six animals. The animals in the control group received distille

The main objective of Structural analysis is to find out the effect of loads on the physical structures and their components. A beam is a structure with a constant cross-section and is described by its significant length in comparison to its thickness and width. A cantilever, on the other hand, is a slender beam with a uniform cross-sectional shape that is fixed horizontally at one end and subjected to a load at the other end. Columns, which serve as vertical compression members in building frames, are susceptible to buckling and failure when subjected to relatively small axial loads. The analysis of loaded beams, cantilevers, and elo

The mean ADA activity and specific activity in type 1 was (8.85± 5.55 U/mg of protein) which is compared with control (32.11± 1.54 U/mg of protein) while in type 2 was (48.46±11.91 U/mg of protein) is compared with control (5.18± 2.27 U/mg of protein ).
