On fractional integro-differential inclusions via the extended fractional Caputo–Fabrizio derivation

Abstract: We first show that four fractional integro-differential inclusions have solutions. Also, we show that dimension of the set of solutions for the second fractional integro-differential inclusion problem is infinite dimensional under some different conditions.

On fixed points of α-ψ-contractive multifunctions

Abstract: Recently Samet, Vetro and Vetro introduced the notion of α-ψ-contractive type mappings and established some fixed point theorems in complete metric spaces. In this paper, we introduce the notion of -contractive multifunctions and give a fixed point result for these multifunctions. We also obtain a fixed point result for self-maps in complete metric spaces satisfying a contractive condition.

Analysis and Implementation of a New SEPIC-Based Single-Switch Buck–Boost DC–DC Converter With Continuous Input Current

Abstract: In this paper, a novel buck–boost dc–dc converter with continuous input current is proposed The voltage gain of the presented converter is higher than conventional converters, such as buck–boost, single-ended primary-inductance converter, Cuk, and Zeta converters This converter works only by one switch and voltage stress across the switch is low Input current of the proposed converter is continuous so a large filter at the input is not needed Furthermore, continuous input current has made this converter suitable for renewable energy and fuel cell applications In this converter, noninverting output voltage is obtained and high gain of voltage is achieved as well So it can operate at wide output voltage range only by changing the duty cycle of the power switch pulse The presented converter can easily controlled in continuous conduction mode operation, because of using only one power switch In the following, the principle of operation and the mathematical analyses of the proposed converter are explained, finally, validity of the proposed dc–dc converter is verified by the experimental results

Effects of nanoparticulate anatase titanium dioxide on physiological and biochemical performance of Linum usitatissimum (Linaceae) under well-watered and drought stress conditions

Abstract: Drought stress has detrimental effects on growth and yield of plants under arid or semi-arid environment. Because of their potential for modulating the redox status and changing the growth, performance and quality of plants, nano-scale materials are among the research interests of physiologists. This study evaluated the impacts of different concentrations (0, 10, 100, and 500 mg l−1) of nanosized (10–25 nm) titanium dioxide (TiO2) on growth, seed yield, photosynthetic pigment contents, the values of hydrogen peroxide (H2O2) and malondialdehyde (MDA), seed oil, and protein contents in Linum usitatissimum Linea (Linaceae) under sufficient and scarce water conditions. The results showed that application of nanoscale TiO2 at low concentration better improved the morphological and physiological traits of plant compared to other doses particularly under water scare conditions, leading to better plant performance. Enhanced chlorophyll and carotenoids contents were recorded in leaves of nano-anatase TiO2-treated plants under both normal and drought stress conditions, when compared to the control. The levels of H2O2 and MDA in plants exposed to nano TiO2 at 10 mgl−1 were lower than that of other treatments, therefore, lipid peroxidation was less pronounced in such plants. In both well watered and drought stress conditions, the highest values of seed oil and protein contents were obtained in plants treated with nano TiO2 at 100 mg l−1. Therefore, exogenous application of nano TiO2 particles at appropriate concentrations can ameliorate drought stress damage to Flax seed plants as well as increase the drought tolerance with remarkable improvement in physiological process.
