Since about over a quarter of the harvested food is lost due to different types of wastage and spoilage, preservation of food is no less important than production of food. Gamma irradiation technology is one of the most appropriate and prominent technologies that can be applied in preservation of food. Gamma area science, also restrict the spoilage and wastage of castrate various maintain security of benefits gamma irradiation high power of, effortlessly, less it is and economically absence awareness, education socialisation the utilisation of gamma irradiation, there are still several societies, which think that gamma irradiation technology is hazardous and its radiation damages the proteins and genes. In fact, preservation of food using nuclear irradiation has been tested, researched and inspected and presently marketable practice in different nations. Gamma irradiation technology is still required to be advanced and it is encouraged so that it can be applied extensively through the regulation that is decided by the administrations to enhance the information of peoples about the advantage of nuclear irradiation power. It is also be considered that irradiated food and foodstuffs and the research outputs of the technology must be socialised, advertised, and published in a variability of advertising mode both in public community and scientific society, so that irradiated food and foodstuffs can be documented and recognised by various communities.

Abstract BackgroundIt is important to know the biomechanical properties of an allograft. This is because when looking to do a transplant of a tendon, the tendon must have very similar biomechanical properties to the original tendon. To use tendon allografts, it is critical to properly sterilize the tendon before implantation. In past decades, several sterilization procedures have been used. This study aimed to systematically evaluate the existing literature to compare the values of failure load/ultimate strength and Young’s modulus of elasticity of different sterilization methods on commonly used tendon allografts. Five major scientific literature databases (Web of Science, Science Direct, Scopus, PLOS ONE, Hindawi) and additional sources were used.ResultsStudies used had to show a particular sterilization method. Studies were identified to meet the following inclusion criteria: is a controlled laboratory study, gamma irradiation (dose reported), and other sterilization methods. Search for publications dated between 1991 and March 31st, 2020. A total of 54 articles have been included. Data collected from the full-text assessment included: a) author and date, b) type of tendon, c) type of sterilization, d) sterilization dose, and g) measured and calculated parameters. Different types of sterilization methods used before tendon durability testing have been identified and categorized.ConclusionsIdentified sterilization methods (gamma irradiation, dry ice, supercritical carbon dioxide (SCCO2), BioCleanse, Electron Beam) are offered as a catalog of potential methods.As a result of the broadness of the present research, it provides an overview of sterilization methods. It does not stand for the state-of-the-art of any single process.

The article provides a comparative analysis of the structures of synchronization of the motion of electric drives of medium and high power. A comparison of synchronization structures is made in terms of the impact on the final operation of the system and hardware synchronization methods in terms of applicability and maximum performance. The mathematical apparatus is based on the principle of separation of the movements of each of the electric drives and the representation of its transfer function in matrix form. The control ranges and speed of different types of systems are compared experimentally by evaluating the speed of data transmission and evaluating the speed ripple at low revs.

A natural-based sodium carboxymethyl cellulose (CMC) hydrogel reinforced with bentonite was prepared by using gamma irradiation technology. This is a novel hydrogel that uses natural polymer to absorb metal ions in wastewater. The influence of dose, concentration of CMC and bentonite on the sorption of hydrogels was investigated by atomic absorption spectrometry (AAS) method. According to the Langmuir isotherm model, the maximum adsorption capacities of CMC/bentonite hydrogel for Cu2+ and Pb2+ were 181.82 mg/g and 204.08 mg/g at room temperature, respectively. The pseudo-second-order model which describes the adsorption process of Cu2+ and Pb2+ was also studied

A super absorbent resin (SAR) of acrylic acid (AA)/acrylamide (AM) /organic montmorillonite (OMMT) composite was synthesized by aqueous solution polymerization. This process was carried out under precision microwave organic synthesis system and its single-mode focusing microwave irradiation technology was studied. The montmorillonite (MMT) was modified by treating with cetyltrimethylammonium bromide. Moreover, the factors that effect on liquid absorbency rate of the SAR were discussed, such as neutralization degree (ND) of AA, microwave irradiation time, microwave irradiation power and the dosage of the OMMT. It gave the best liquid absorbency rate (1520g.g-1 and 165g.g-1 in purified water and 0.9wt% NaCl solution, respectively).
