The role of field redefinition on renormalisability of a general N=12N=\frac{1}{2} supersymmetric gauge theories

We investigate some issues on renormalisability of non-anticommutative supersymmetric gauge theory related to field redefinitions. We study one loop corrections to $N=\frac{1}{2}$ supersymmetric $SU(N)\times U(1)$ gauge theory coupled to chiral matter in component formalism, and show the procedure which has been introduced for renormalisation is problematic because some terms which are needed for the renormalisability of theory are missed from the Lagrangian. In order to prove the theory is renormalisable, we redefine the gaugino and the auxiliary fields($\lambda, \bar F$), which result in a modified form of the Lagrangian in the component formalism. Then, we show the modified Lagrangian has extra terms which are necessary for renormalisability of non-anticommutative supersymmetric gauge field theories. Finally we prove $N = \frac{1}{2}$ supersymmetric gauge theory is renormalisable up to one loop corrections using standard method of renormalisation; besides, it is shown the effective action is gauge invariant.Comment: arXiv admin note: text overlap with arXiv:hep-th/0505248 by other author

Correlation of length and weight with mercury concentration in different tissues of Kutum Roach (Rutilus frisii kutum) in central south of Caspian Sea

We used Mercury Analyzer to assess possible correlation between length and weight of the Kutum Roach (Rutilus frisii kutum) and mercury accumulation in different tissues of the fish. We collected fish specimens from central south Caspian Sea from October to December 2005. After biometrical measurement of samples and sex determination, mercury concentration was assessed in muscle, liver and skin tissues of the specimens. The mean concentration of mercury in muscle, liver and skin tissues was 849.9, 670.9 and 493.7ng/g respectively. Statistical analysis of the results showed a significant difference between mercury amounts in different tissues (P0.05). The mercury amount in muscle of Kutum Roach was lower than permissible limits proposed by FDA (1004ngig)

CO2 Utilization via Integration of an Industrial Post-Combustion Capture Process with a Urea Plant: Process Modelling and Sensitivity Analysis

Carbon capture and utilization (CCU) may offer a response to climate change mitigation from major industrial emitters. CCU can turn waste CO(2)emissions into valuable products such as chemicals and fuels. Consequently, attention has been paid to petrochemical industries as one of the best options for CCU. The largest industrial CO(2)removal monoethanol amine-based plant in Iran has been simulated with the aid of a chemical process simulator, i.e., Aspen HYSYS(R)v.10. The thermodynamic properties are calculated with the acid gas property package models, which are available in Aspen HYSYS(R). The results of simulation are validated by the actual data provided by Kermanshah Petrochemical Industries Co. Results show that there is a good agreement between simulated results and real performance of the plant under different operational conditions. The main parameters such as capture efficiency in percent, the heat consumption in MJ/kg CO2 removed, and the working capacity of the plant are calculated as a function of inlet pressure and temperature of absorber column. The best case occurred at the approximate temperature of 40 to 42 degrees C and atmospheric pressure with CO2 removal of 80.8 to 81.2%; working capacity of 0.232 to 0.233; and heat consumption of 4.78 MJ/kg CO2

Evaluation of expression ratio of HOXB13:IL17BR in patients with breast cancer by qRT-PCR method using SYBR Green dye

Background and aims: Studies have shown that a HOXB13:IL17BR expression ratio index predicts clinical outcome in ER-positive, lymph node-negative breast cancer patients that treated with adjuvant tamoxifen. All of these experiments were conducted with qReal Time RT-PCR using TaqMan probes. The aim of this study was to determine the ratio using SYBR Green I qReal Time RT-PCR. Methods: In this case- control study, expression levels of HOXB13:IL17BR was measured in 40 paired formalin-fixed, paraffin-embedded primary breast tumor specimens. After extracting RNA from the tissues, cDNA synthesis and amplification with the polymerase chain reaction to obtain the optimum annealing temperature, the expression levels was measured by SYBR Green I qReal Time RT-PCR. To determine and normalize the expression levels, BestKeeper software was used to obtain the BestKeeper Index using the geometric mean of expression levels of housekeeping genes. Comparison of mean expression of genes between tumoral and non-tumoral tissues was performed by t-test and association between patient grouping (high/low risk) and time for disease free survival was assessed by Fisher`s Exact test. Results: HOXB13:IL17BR expression value did not show significant difference between tumoral and non-tumoral tissues. The results showed that there was a direct and significant association between patient grouping (based on HOXB13:IL17BR ratio) and disease free survival status. Conclusion: Results in the current study showed that in spite of using SYBR Green dye (instead of TaqMan probes), there is still a significant correlation between HOXB13:IL17BR ratio and disease free survival status

Perfluorocarbon liquid migration into the subarachnoid space in a patient with morning glory syndrome

Purpose: To report a case of perfluorocarbon liquid (PFCL) migration into the subarachnoid space at the time of vitreoretinal surgery in a patient with morning glory syndrome associated retinal detachment. Case report: A 9-year-old girl underwent pars plana vitrectomy and silicone oil injection for retinal detachment associated with morning glory syndrome. PFCL was used for retinal stabilization before endolaser photocoagulation. The retina detached, and repeated vitrectomy and silicone oil injection was performed. Postoperative magnetic resonance imaging revealed PFCL in the subarachnoid space. Conclusion: The migration of perfluorocarbon into the subarachnoid space is a rare complication of vitrectomy in patients with morning glory syndrome. © 2015 Iranian Society of Ophthalmology

Techno-economic assessment and optimization of a solar-assisted industrial post-combustion CO2 capture and utilization plant

This paper studies the techno-economic feasibility of the solar-assisted regeneration process of the largest industrial CO2 removal monoethanolamine-based plant in Iran. The plant incorporating parabolic troughs is modelled using System Advisor Model software and the weather data are derived from the European Commission''s Photovoltaic Geographical Information System. Sensitivity analyses are realized to evaluate the effect of important parameters, i.e., the solar multiple and the hours of storage, and to reveal the optimum case. The studied impacts are linked to the overall net energy generation and the levelized cost of heat (LCOH). The optimum case is found to have a solar multiple of 3.1 and 18-hours of storage, resulting in a solar share of 0.7 and a LCOH of 3.85 (¢/kWh). When compared to the base case (solar multiple of 2 and 6 h of storage), the optimum solution results in a similar LCOH but it achieves the generation of an additional 16, 112 MWhth annually. The thermal energy supplied by the solar system leads to an annual reduction in the natural gas consumption of approximately 3.8 million m3 that results in a CO2 emission reduction of 7.1 kton. © 2021 The Author

Free Reducing Agent, One Pot, and Two Steps Synthesis of Ag@SiO[2] Core-shells using Microwave Irradiation

In this work a new method for the fabrication of Ag@SiO[2] nanoparticles have been proposed that is completely different from Stober method. Ag nanoparticles were synthesized using microwave irradiation. polyvinylpyrrolidone was used as stabilizer and capping agent, 3-Aminopropyltriethoxysilane as functionalizer of silver particles in fully ethanol solution. The Ag nanoparticles were used subsequently without any subtraction and treatment in the preparation of Ag@SiO[2] core-shell nanoparticles. UV-Vis spectroscopy shows a characteristic plasmon peak at 400 nm and 430 nm for Ag nanoparticles and Ag@SiO[2] coreshells. Transmission electron microscope images show that Ag nanoparticles have the average size of 10 nm. It is also depicted that SiO[2] shell structure was formed uniformly with the average size of 10 nm. The application of 3-Aminopropyltriethoxysilane in the preparation of core-shells yields single Ag core structure

Nanostructured multifunctional stimuli-responsive glycopolypeptide-based copolymers for biomedical applications

Inspired by natural resources, such as peptides and carbohydrates, glycopolypeptide biopolymer has recently emerged as a new form of biopolymer being recruited in various biomedical applications. Glycopolypeptides with well-defined secondary structures and pendant glycosides on the polypeptide backbone have sparked lots of research interest and they have an innate ability to self-assemble in diverse structures. The nanostructures of glycopolypeptides have also opened up new perspectives in biomedical applications due to their stable three-dimensional structures, high drug loading efficiency, excellent biocompatibility, and biodegradability. Although the development of glycopolypeptide-based nanocarriers is well-studied, their clinical translation is still limited. The present review highlights the preparation and characterization strategies related to glycopolypeptides-based copolymers, followed by a comprehensive discussion on their biomedical applications with a specific focus on drug delivery by various stimuli-responsive (e.g., pH, redox, conduction, and sugar) nanostructures, as well as their beneficial usage in diagnosis and regenerative medicine.Peer reviewe
