It has long been recognized that combined heat and power (CHP) generation can achieve higher end-use efficiencies than conventional systems. By generating electricity at the point of use and utilizing the co-produced heat, CHP generators can achieve net efficiencies in excess of 80%. This nearly doubles the efficiency of our current system, in which large centralized power plants provide electr...
مفهوم ریزشبکه به مجموعه ای از بارها،منابع تولید مقیاس کوچک و واحدهای ذخیره ساز اطلاق می شود که به صورت یک بار قابل کنترل یا ژنراتور عمل می کنند و می توانند توان و گرما را برای ناحیه محلی فراهم کنند. ریز شبکه می تواند جهت دستیابی به توان پایه، توان اوج، توان پشتیبان، توان نواحی دوردست، کیفیت توان و نیاز های سرمایی و گرمایی به کار رود. کاهش آلودگی گازها، بازده انرژی، تنوع منابع انرژی و نیازهای تو...
Background. Adequate fluid management could be essential to minimize high arterial stiffness observed in chronically hemodialyzed patients (CHP). Aim. To determine the association between body fluid status and central and peripheral arterial stiffness levels. Methods. Arterial stiffness was assessed in 65 CHP by measuring the pulse wave velocity (PWV) in a central arterial pathway (carotid-femo...
Background: So far, the association of lung cancer with chronic hypersensitivity pneumonitis (CHP) has not been studied. Objective: We examined the prevalence and revealed clinical features of lung cancer in CHP. Methods: We retrospectively reviewed the medical records from 1994 through 2005 and identified 11 patients (15 lesions) with lung cancer among 104 patients with CHP. Their clinical fea...
Biogas is a proven and valuable energy source today for combined production of heat and electricity (CHP). In this paper, a novel CHP system installation based on a 500 kW micro humid air turbine (mHAT) in a wastewater treatment plant (WWTP) is presented and discussed. Furthermore, some considerations regarding an appropriate biogas treatment system and heat recovery module is discussed. The re...
Utilization of combined heat and power (CHP) systems that simultaneously fulfill the electrical and heating energy needs is considered as an effective strategy for management of energy demand and consumption. Overall operational efficiency in excess of 70% is made possible, when these systems are utilized, and it is expected that needs for both the demand and supply sides are met even under ...
Simulations of greenhouse gas emission reductions from low-cost hybrid solar photovoltaic and cogeneration systems for new communities, Simulations of greenhouse gas emission reductions from low-cost hybrid solar photovoltaic and cogeneration systems for new communities, Abstract Recent work has shown that small-scale combined heat and power (CHP) and solar photovoltaic (PV) technologies have s...
Decellularized extracellular matrix (ECM) derived from tissues and organs are emerging as important scaffold materials for regenerative medicine. Many believe that preservation of the native ECM structure during decellularization is highly desirable. However, because effective techniques to assess the structural damage in ECM are lacking, the disruptive effects of a decellularization method and...
Three new tissue culture cell lines, CHP-100, CHP-126, and CHP-134, have been established from explant cultures of human neuroblastoma. The cell lines have been characterized with respect to morphology, chromosomes constitution, growth, neural enzyme content, and their ability to grow in nude mice. The cells grow as dense masses comprised of fibroblast-or neuroblast-like cells with small proces...
