The Effect of Extreme Temperature Fluctuations Simulated of Space on the Electrophoretic Profile of Tomato (Lycopersicum esculentum Mill.) Seed Storage Proteins

Fateme Mousavi

Volume 16, Issue 4 , December 2023, , Pages 83-89

Abstract
  Seed aging is a process that can lead to a complete loss of seed viability. This process occurs when seeds are exposed to long-term storage or controlled deterioration treatments such as excessive dryness, lack of oxygen, and temperature fluctuations on Earth or in outer space. Proteomic changes can ...  Read More

Plant Germplasm and Extreme Conditions of Outer Space

Fateme Mousavi

Volume 16, English Special Issue , November 2023, , Pages 65-71

Abstract
  The extreme temperature fluctuations and the vacuum of the space environment make growing plants in outer space challenging. To simulate the temperature fluctuations and vacuum conditions associated with space environments, dry tomato seeds were placed in a thermal cycle simulator and vacuum simulator ...  Read More

Cost Estimation for Space Propulsion Systems and Human Resource Cost and The Project Implementation Time Optimization

Hassan Naseh; Mostafa Jafarpanah

Volume 15, Issue 3 , September 2022, , Pages 79-92

Abstract
  The purpose of this paper is to present the cost estimation and optimization of space propulsion systems. Thus, choosing optimal propulsion system (from fuel and oxidizer aspect) is done in order to increase the efficiency and decrease the cost. Also, human resource cost and technology development time ...  Read More
