Background and Objectives: Despite unique characteristics of tahini, adequate biotechnical studies have not been carried out on tahini. In recent decades, functional food production such as probiotics has increased because of positive effects on the consumer health. Studies have verified that probiotics do not include appropriate survivability in fat ambiences. Hence, the present study was carr...
Time-domain electromagnetic (TDEM) migration is based on downward extrapolation of the observed field in reverse time. In fact, the migrated EM field is the solution of the boundary-value problem for the adjoint Maxwell's equations. The important question is how this imaging technique can be related to the solution of the geoelectrical inverse problem. In this paper we introduce a new formulati...
Angle-gather migration creates seismic images for different reflection angles at the reflector. We formulate an angle-gather time migration algorithm and study its properties. The algorithm serves as an educational introduction to the angle gather concept. It also looks attractive as a practical alternative to conventional common-offset time migration both for velocity analysis and for AVO/AVA ...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
Rural migration is being considered as an important phenomenon as far as the economic planners in developing counties are concerned. One type of this migration heading toward Arab neighboring countries located in Persian Golf Basin. The major objective of this study is to compare income level and standard of living of the rural migrants as opposed to non-migrant ones in Larestan County. Data we...

Reverse Time Migration technique produces underground images using wave propagation. A discretization based on the Discontinuous Galerkin Method unleashes a massively parallel elastodynamics simulation, an interesting feature for current and future architectures. In this work, we propose to combine two recent HPC techniques to achieve a high level of efficiency: the use of runtimes (StarPU and ...
Clinical applications of mesenchymal stem cells (MSCs) rely on their capacity to home and engraft in the appropriate target tissues for a long time. Homing and engraftment capacity of these stem cells depend on the expression of Chemokines and their receptors. Ex vivo expanded MSCs exhibit homing potential when grafted to injury tissue but their homing efficiency has been observed very poor bec...
Insulation of solid propellant to controlling and limiting the burning surface and also to avoid of heat transfer to the solid rocket body is done. This type of coating is defined as inhibitors of combustion. Unsaturated polyesters such as polyurethane are used for good chemical compatibility between double base propellant and inhibitor. In this article, the effect of aromatic groups and the ef...
Background and Objectives: Prostate cancer is the third most important cause of cancer deaths and one of the most common cancers in the world. Given the limited knowledge on environmental sounds and their effects, the important role of sounds is neglected in every culture across the world. The aim of this study was to investigate the impact of Quran recitation on prostate cancer cell line (PC-3...
