The aim of the study is to present an economic analysis of a micro cogeneration system using financial analysis (energy view) and exergoeconomic analysis (exergy view). This system uses a natural gas-fueled 30 kW microturbine to generate electricity, and to produce hot water by recovering energy from the waste heat in the exhaust gases by using a heat exchanger, which serves as the drive source...
The research literature on gambling behavior indicates that American Indians (AIs) suffer from pathological gambling at a greater rate than the majority population. The literature also suggests that dispositional factors, such as sensation seeking, can influence gambling. However, situational factors, such as the payback percentage of a slot machine, may not. The present study recruited 12 AI a...
Abstract Cold thermal energy storage is an active method for reducing the peak electrical demand and electricity consumption of air conditioners. This paper investigates two different cases: partial operating mode–load levelling (POM–LL) demand-limiting mode (DLM). 4E (energy, exergy, economic, environment) analyses along with a multi-objective optimization process based on genetic algorithm ap...
Hybrid renewable energy systems (HRES) with potential environmental, economic and social benefits are designed to improve energy efficiency and reliability. In this study, artificial intelligence and smart grids were studied to supply electricity for a green cottage. The obtained results are essential for designing, implementing, and building HRES. Three cost-benefit and environmental, economic...

Extraction and processing of oil products consume 10% of the total energy produced by fossil resource. to prevent operational problems in downstream units Oil extracted from oil fields will be sent to the desalting plant for desalination and dehydration. One of the most important steps that have a vital role in this unit is pre-heating by heaters which use natural gas produced with crude oil at...
In the study nasal and throat swabs were collected from 78 apparently healthy and 69 cases of kennel cough from dogs of different age, sex, breed and places and analysed for presence of Bordetella bronchiseptica through bacterial isolation and multiplex PCR (mPCR). The pathogen could be isolated from an apparently healthy Labrador bitch while with mPCR, 7 (4.76%, 4 from healthy dogs and 3 from ...
