Conceptual Difficulties

<p>There are extensive conceptual difficulties in understanding a country’s energy story. Every country in the world uses some combination of energy production, imports, and exports energy to meet their society’s needs. Thermal inefficiencies converting primary energy into electricity further confuse the issues. A visualization using large, publicly available data can help illustrate these different energy perspectives. This data visualization helps clarify the following perspectives: Production, Imports, Exports, Total Primary Energy Supply (TPES), Total Final Consumption (TFC), and the conversion losses from turning TPES into TFC. TPES refers to the total amount of energy a country obtains directly from natural resources such as fossil fuels or wind. TFC refers to the addition of the all energy directly consumed by a user for an energy service such as electricity for lighting in a house. This paper discusses the interactive simulation that was built to allow users to explore the composition of a country’s energy production, imports and exports through the conversion into energy people consume. The simulation allows users to explore the energy stories for different countries, and how these change over the decades.</p>

Life On Earth

Water is the fundamental element for the existence of life on earth is one of the essential natural resources used by humans. The use of alternative sources of water in public and private bodies has been the most constant form in recent years, this time aiming to reduce the demand for drinking water. The management of water use and the search for alternative sources of supply such as rainwater use fall within the context of sustainable development, which proposes the use of natural resources in a balanced way and without harming future generations. Thus, the design of the reservoir for the use of rainwater at the Manacapuru Metropolitan Faculty of Manacapuru - UEA, by the methods provided by the NBR 15527/2007 guidelines were satisfactory. With ten-year rainfall data from 04/2008 to 12/2017, in the municipality of Manacapuru, the volume found for the reservoir to meet the analyzed rainwater demand was 37.17 m³, with a supply of approximately 80% of non-potable water consumption at Manaus Metropolitan Faculty Manacapuru unit. Thus the economic advantages, the implementation of this sustainable system can bring benefits to the environment, so all the water collected will help to minimize the occurrence of floods and the improper consumption of treated water.

Food And Feed

This paper gives an account of the issues at play in Europe with regard to the transition to a bio-based economy. Agricultural crops have always been used for the production of food, feed, fibre and fuel. The Model T Ford—the first mass produced car—originally ran on bioethanol, and wood has been in use as a source for energy ever since the discovery of fire. What is new is that the balance between agricultural uses is changing under the pressure of an increasing need for food and feed, as well as the new need for biofuels and biomaterials. At the basis of this change lie several serious issues related to the current use of bio-based feedstock to secure energy supply, the future depletion of natural resources and global climate change. Innovations in industrial biotechnology are expected to play a crucial role in dealing with these issues in biomass use.

AbstractOne of the peculiar aspects of living systems is the production and conservation of energy. This aspect is provided by specialized organelles, such as the mitochondria and chloroplasts, in developed living organisms. In primordial systems lacking specialized enzymatic complexes the energy supply was probably bound to the generation and maintenance of an asymmetric distribution of charged molecules in compartmentalized systems. On the basis of experimental evidence, we suggest that lipophilic quinones were involved in the generation of this asymmetrical distribution of charges through vectorial redox reactions across lipid membranes.

Multi Objective

Due to the increase in energy demand, many countries suffer from energy poverty because of insufficient and expensive energy supply. Plans to use alternative power like nuclear power for electricity generation are being revived among developing countries. Decisions for installation of power plants need to be based on careful assessment of future energy supply and demand, economic and financial implications and requirements for technology transfer. Since the problem involves many vague parameters, a fuzzy model should be an appropriate approach for dealing with this problem. This study develops a Fuzzy Multi-Objective Linear Programming (FMOLP) model for solving the nuclear power plant installation problem in fuzzy environment. FMOLP approach is recommended for cases where the objective functions are imprecise and can only be stated within a certain threshold level. The proposed model attempts to minimize total duration time, total cost and maximize the total crash time of the installation project. By using FMOLP, the weighted additive technique can also be applied in order to transform the model into Fuzzy Multiple Weighted-Objective Linear Programming (FMWOLP) to control the objective values such that all decision makers target on each criterion can be met. The optimum solution with the achievement level for both of the models (FMOLP and FMWOLP) are compared with each other. FMWOLP results in better performance as the overall degree of satisfaction depends on the weight given to the objective functions. A numerical example demonstrates the feasibility of applying the proposed models to nuclear power plant installation problem.

Indonesia is one of many countries in the world so called resource-rich country. Natural resources abundance needs to be managed in the right way in order to avoid dutch diseases and resources curses. These two phenomena generally happened in the country, which has abundant natural resources. Learned from Norwegian experiences, Indonesian Government need to focus its policy to prevent rent seeking activities. The literature study presented in this paper is aimed to provide important insight for government entities in focusing their policies and programs to avoid resources curse. From the internal audit perspective, this study is expected to improve internal audit’s role in assurance and consulting.
