In today?s world, we are facing the problem of fossil fuel depletion along with its cost continuously increasing. Also, it is getting difficult to live in a pollution free environment. Solar energy one most abundantly and freely available form energy. Out various ways harness solar energy, thermal efficient as compared photovoltaic technology. There cycles convert mechanical work, but Kalina cy...

Ocean thermal energy conversion (OTEC) uses a very simple process to convert the stored mainly in tropical oceans into electricity. In designs, operations, and evaluations, we need consider unique characteristics of OTEC achieve best performance or lower electricity cost projects. The concept design constraints power generation differ from those conventional plants due utilization low temperatu...

Three heat recovery cycles are studied to recover the waste from exhaust gas outlet of a glass-melting furnace. To determine viability and potential dangers based on techno-economic aspects, three fundamental for UK glass melting furnaces examined. The parametric thermodynamic study reveals effects key parameters: condenser temperature ORC cycle, pressure ratio sCO2 flash Kalina cycle. paramete...

In order to achieve both power and cooling supply for users, a new combined cooling and power system using ammonia–water mixture is proposed to utilizing low grade heat sources, such as industrial waste heat, solar energy and geothermal energy. The proposed system combines a Kalina cycle and an ammonia–water absorption refrigeration cycle, in which the ammonia–water turbine exhaust is delivered...

Across the continent, many Native American and Canadian First Nations people are linguistically constructing a shared ethnic identity through English dialect features. Although many tribes and regions have their own localized English features (e.g., Leap 1993, Bowie et al. 2013, Dannenberg and Wolfram 1998, Coggshall 2008), we suggest that certain features may be shared across much wider distan...

There are many peptides known that inhibit the entry of enveloped viruses into cells, including one peptide that is successfully being used in the clinic as a drug. In this review, we discuss the discovery, antiviral activity and mechanism of action of such peptides. While peptide entry inhibitors have been discovered by a wide variety of approaches (structure-based, accidental, intentional, ra...
