Several studies have been carried out by optimising only the cost. They have not considered some other risk factors such as political and economic factors in their modelling. Currently, there is no generalised model available to determine the optimal sourcing locations incorporating important factors including risks in international LNG trading. In this study, 12 risk factors were taken into consideration to evaluate the risk.

This research aims to address these research gaps. Through the literature review, the most popular building PV applications in China are identified. Hence, five building PV scenarios are developed based on real-word cases, including BAPV, roof BIPV and window BIPV. Given the diverse geographic conditions and policy conditions in China, 12 typical cities are selected for the research. A MATLAB program is established to calculate energy generation and evaluate the economic performance of the building PV applications in the 12 cities.

Sweet sorghum is a new generation bio-energy crop with considerable tolerance to drought and salinity and amenable for multiple uses. Sweet sorghum has elicited the interest of breeder due to its capacity to provide renewable energy products, industrial commodities, food and animal feed. The sweet sorghum donor RSSV 313 is developed through a cross NSS223 x NARI 111 at MPKV, Rahuri through pedigree selection as identified and recommended as a donor parent in crop improvement programme based on specific physiological traits viz.

When a satellite is in orbit, micro vibration generated by its actuators (such as reaction wheels, deployable mechanisms, etc.) will affect the imaging quality of the camera. Viscoelastic materials are utilized as passive isolators to reduce these micro vibrations due to their simple construction and excellent energy dissipation capacity.

The use of solar energy has been adduced as an alternative way for generating electricity. This electricity is generated by solar panel but as temperature increases efficiency of panel decreases too. The main objective of this research paper is to minimize the use of the amount of water, electrical energy and required time needed for cooling of a solar panel.

Mitochondrial functional and structural impairment and generation of oxidative stress have been implicated in aging, various diseases and chemotherapies. This study analyzed azidothymidine (AZT)-caused failures in mitochondrial functions, in redox regulation and activation of the HIV-1 gene expression. We monitored intracellular concentrations of ATP and glutathione (GSH) as the indicators of energy production and redox conditions, respectively, during the time-course experiments with U937 and MOLT4 human lymphoid cells in the presence of AZT (0.05 mgÆmL)1) or H2O2 (0.01 mM) for 15–25 days.

Grid-connected photovoltaic power systems are power systems energised by photovoltaic panels which are connected to the utility grid. Grid-connected photovoltaic power systems comprise of Photovoltaic panels, MPPT, solar inverters, power conditioning units and grid connection equipments. Unlike Stand-alone photovoltaic power systems these systems do not have batteries. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.[1]...
