AIMS The aim of this study was to investigate whether the sera from chronic chagasic patients (CChPs) with beta-1 adrenergic activity (Ab-beta) can modulate ventricular repolarization. Beta-adrenergic activity has been described in CChP. It increases the L-type calcium current and heart rate in isolated hearts, but its effects on ventricular repolarization has not been described. METHODS AND ...

Reclaimed water from wastewater has become a prominent source option to manage scarcity. This study explores the potential of coconut husk biomass, common waste material in Ghana, as valuable low-cost resource for greywater treatment. Engineered column treatment was applied investigate influence pyrolysis and biochar properties biomass on Coconut pyrolyzed at 600°C characterized using SEM, FTIR...

The aim of this work is to investigate a novel integrated cooling, heating, and power (CCHP) system with biomass gasification, solid oxide fuel cells (SOFC), micro-gas turbine, absorption chiller. performance analyzed by mathematical models consisting lumped SOFC chiller one-dimensional model downdraft gasifier. Effects main operating parameters such as moisture content biomass, air flow rate i...

The optimized dispatch of different distributed generations (DGs) in stand-alone microgrid (MG) is of great significance to the operation’s reliability and economy, especially for energy crisis and environmental pollution. Based on controllable load (CL) and combined cooling-heating-power (CCHP) model of micro-gas turbine (MT), a multi-objective optimization model with relevant constraints to o...

Background: The available data on cryptogenic chronic hypersensitivity pneumonitis (ccHP) indicate an inherited predisposition to disease with triggering autoimmune phenomena. Hence, we evaluated prospectively the role of a new regimen in treatment its severe and progressive disease. Patients Methods: A total 9 patients were included study. They had criteria for ccHP viz. 1) clinical features r...

This paper proposes a combined cooling, heating and electric power (CCHP) system based on demand side response. In order to improve the economy of system, two-stage optimal scheduling scheme is proposed with goal minimizing total operating cost maximizing user satisfaction. The operation was divided into two optimization problems, including supply side. first stage, satisfaction, from new point...

Internet data centers are growing rapidly in recent years and they operate with intensive energy activity. Combined cooling, heating power (CCHP) brings new opportunities for reducing the electricity cost internet centers. The main objective of this study is to optimize resources scheduling center coupled nets considering involvement CCHP different demand response techniques. In paper, proposed...

Abstract As the basis for study, this manuscript was written at a time when energy crisis is affecting most parts of world and especially prevailing rampant electricity in developing countries. result, 50 combined cooling, heating power (CCHP) systems studies were reviewed, which included internal combustion engine (ICE), Stirling engine, biomass, micro turbine, solar biogas, photovoltaic (PV) ...

This paper presents the achievements in solid sorption refrigeration prototypes obtained since the interest in sorption systems was renewed at the end of the 1970s. The applications included are ice making and air conditioning. The latter includes not only cooling and heating, but also dehumidification by desiccant systems. The prototypes presented were designed to use waste heat or solar energ...
