Effects of ultrasonic on microorganisms and enzymes

Removing on pathogens is the key concern of non-thermal technology in food products. Recently, inclusion of ultrasound into the food industry has been a subject of research and development. The application of ultrasound in food industry is undoubtedly the notion of consideration and development and, the same as other cases in other areas, the sound ranges can would fall into the following categories of high frequency, low energy, diagnostic ultrasound in the MHz range and low frequency, high energy, power ultrasound in kHz range. The advantageous application of power ultrasound is reflected in its chemical, mechanical, or physical effects on the process or product. Microorganisms Inactivation mechanism, based on physical and chemical factors that ultrasonic was caused on liquid food. When it comes to physical and chemical effects, one would distinguish between them as thinning cell membrane, localized heat and pressure changes (5500°C, 50Mpa); hydroxyl radical and sonochemical reactions, respectively. Ultrasound-assisted inactivation of microorganisms and enzymes brings about the extension of shelf life of raw materials or prepared foods. The study focuses on the related literature having to do with the effect of ultrasonic on microorganism and enzymes

N-fold Supersymmetry in Quantum Systems with Position-dependent Mass

We formulate the framework of N-fold supersymmetry in one-body quantum mechanical systems with position-dependent mass (PDM). We show that some of the significant properties in the constant-mass case such as the equivalence to weak quasi-solvability also hold in the PDM case. We develop a systematic algorithm for constructing an N-fold supersymmetric PDM system. We apply it to obtain type A N-fold supersymmetry in the case of PDM, which is characterized by the so-called type A monomial space. The complete classification and general form of effective potentials for type A N-fold supersymmetry in the PDM case are given.Comment: 18 pages, no figures; Refs. updated, typos correcte

The Effect of Silymarin on Serum Concentration of Soluble Apoptosis Markers in β-Thalassemia Major Patients Receiving Desferrioxamine

ABSTRACT Background: Despite appropriate chelation therapy with desferrioxamine, iron deposition in visceral organs causes tissue damage in thalassemia major patients. Excess iron can generate reactive oxygen species (ROS) that may lead to cell death and apoptosis. Therefore, antioxidants such as plant flavonoids can be an effective treatment to reduce ROS in thalassemia patients. Aims: In this study, we aimed to investigate the serum levels of apoptosis markers in βthalassemia major patients treated with silymarin and ..

Evaluation of the Effect of different microwave dryer power on the Qualitative and Quantitative properties of Essential oil of Bakhtiari Savory

Drying is one of the most important post-harvest stages of medical plants which has a significant effect on the quality and quantity of the effective compounds. In order to promote the objectives of the study, microwave power was selected as an independent variable so that power variable microwave was designed and constructed. After collection and drying the savory samples in the shade, the essential oil at different treatments was extracted in three levels of 400, 600 and 800 W. The volatile oil was analyzed using GC/MS method. Results of experiments showed that increase in the power from 400 W to 600 and 800 W caused a reduction in drying time. The most yield of essential oil was obtained in the shade drying method with the essence value of 2.41%. It was also revealed that with increasing the microwave power, the amount of essence decreased, so that the microwave power of 800 W had the lowest essence value. The highest values of thymol and carvacrol and sum of them that show the quality of essential oil was obtained in drying methods with microwave power of 800 W (56.83%). Overall, when the quality of essence is important, the common method of shade drying is suggested, while considering the speed and quality, the microwave drying is recommended

Non-Simplified SUSY: Stau-Coannihilation at LHC and ILC

If new phenomena beyond the Standard Model will be discovered at the LHC, the properties of the new particles could be determined with data from the High-Luminosity LHC and from a future linear collider like the ILC. We discuss the possible interplay between measurements at the two accelerators in a concrete example, namely a full SUSY model which features a small stau_1-LSP mass difference. Various channels have been studied using the Snowmass 2013 combined LHC detector implementation in the Delphes simulation package, as well as simulations of the ILD detector concept from the Technical Design Report. We investigate both the LHC and ILC capabilities for discovery, separation and identification of various parts of the spectrum. While some parts would be discovered at the LHC, there is substantial room for further discoveries at the ILC. We finally highlight examples where the precise knowledge about the lower part of the mass spectrum which could be acquired at the ILC would enable a more in-depth analysis of the LHC data with respect to the heavier states.Comment: 42 pages, 18 figures, 12 table

Potential algebra approach to position dependent mass Schroedinger equation

It is shown that for a class of position dependent mass Schroedinger equation the shape invariance condition is equivalent to a potential symmetry algebra. Explicit realization of such algebras have been obtained for some shape invariant potentials

Effects of light regimes on growth and survival of Penaeus semisuleatus

We investigated the possible effects of light regimes on growth and survival rate of juvenile shrimp Penaeus semisuicants cultured in Bushehr Province, southern Iran. Five light regimes each with three replications were applied for 30 days. The treatments were 24 1 0, 18 / 6, 12 1 12, 6 1 18 and 0 124 hours of light and darkness. We found that the treatment 12 7 12 hours of light and darkness was better than 18 1 6 and significantly superior to other treatments (P<0.05). The lowest growth rate was seen in the treatment 24 / 0 (P<0.001 ). We did not find a significant difference in the survival rate of the shrimps cultured in the light and darkness treatments (P<0.05)
