Diversity of arbuscular mycorrhizal fungi and its chemical drivers across dryland habitats
(
Springer
, 2021 , Article)
Qatar is largely characterized by a hyper-arid climate and low soil fertility which create a stressful soil environment for arbuscular mycorrhizal (AM) fungi. In a study of AM fungal communities and their relationship with ...
Understanding diabetes-induced cardiomyopathy from the perspective of renin angiotensin aldosterone system
(
Springer
, 2021 , Article)
Experimental and clinical evidence suggests that diabetic subjects are predisposed to a distinct cardiovascular dysfunction, known as diabetic cardiomyopathy (DCM), which could be an autonomous disease independent of ...
Performance Enhancement of PPMIM Drives by Using Three 3-Phase Four-Leg Inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In this article, a multilevel inverter (MLI) scheme is proposed for 9-phase pole phase modulated induction motor (PPMIM) drives. The proposed inverter scheme is realized with the help of three 3-phase four-leg inverters. ...
Experimental and numerical analysis of heat transfer and fluid flow characteristics inside pulsating heat pipe
(
Taylor and Francis Ltd.
, 2021 , Article)
Heat pipes are a popular choice for many industries and research applications to extract heat effectively by maintaining desired device/location at almost isothermal conditions. Pulsating heat pipes, also known as wickless ...
A simplified methodology for renewable energy integration and harmonic current reduction in hybrid micro grid
(
Taylor and Francis Ltd.
, 2021 , Article)
Due to advancements in power electronics devices and the support of improvements on both the power supply and load sides, Distributed Energy (DG) is rapidly being connected to the grid in the form of AC/DC Hybrid Micro-Grid ...
Photocatalytic and antimicrobial properties of microwave synthesized mixed metal oxide nanocomposite
(
Elsevier B.V.
, 2021 , Article)
CdO-CuO-ZnO nanocomposite (CCZ NC) was prepared by a simplistic microwave-assisted route and inspected by utilizing diverse spectroscopic ways. The structural and morphological properties of CCZ NC were investigated via ...
A simplified methodology for mitigating the harmonics and common-mode voltage using multi-level inverters for renewable energy applications
(
Taylor and Francis Ltd.
, 2021 , Article)
Multi-level inverters have outstanding construction, making it feasible to achieve high voltage levels with less THD value. These harmonics can be mitigated by decreasing the number of voltage switches and DC links in the ...
A review on thermochemical biomass gasification techniques for bioenergy production
(
Taylor and Francis Ltd.
, 2021 , Article Review)
Thermochemical gasification techniques (TCG) are used for producing gaseous fuel from solid fuel to bioenergy production. One of the needs is for solid waste to diversify into energy sources; thermochemical gasification ...
A novel design of switched boost action based multiport converter using dsPIC controller for renewable energy applications
(
Taylor and Francis Ltd.
, 2021 , Article)
Traditionally the grid supplies only a particular voltage to the load, but today we are using 'n' number of loads with different voltage rating and converters. So, the conversion of the generated AC voltage into several ...
