It could be seen from the past, process of the promoting progress of human society's tends to demanding for energy.With the advancement of technology development as time goes on, countries spare no effort to develop new energy sources, while also continue digging traditional industrial energy. Since the 1960`s, people in the field of shale gas exploitation has made substantial progress. For the development of new energy storage proposed higher requirements, in order to meet growing energy needs, for geotechnical engineering particularity, from the numerical simulation of hydraulic fracturing start by comparing different stress crack formation in case of carry case, at the conclusion on the basis of experimental results can be applied to specific projects put forward the basic assumptions.

Abstract The Kenyan photovoltaic industry has been growing steadily in recent years. Since 1990 more than 2.5 megawatts of photovoltaic capacity have been sold in Kenya and 60% of these sales have gone into home systems as part of new energy supplies. The demand for energy in Kenya exceeds the supply and for this reason renewable energy is regarded a priority in the energy sector. A solution to this problem lies in four areas: technology development, environmental protection, energy economics and socio-cultural adjustments. This paper discusses the state of current research and applications of stand-alone building-integrated PV home systems by looking at the possibilities and limitations in this developing country. Houses need a PV panel-surface area of about 36m2 to meet basic energy needs.

Induced Seismic Activity

High-volume hydraulic fracturing combined with horizontal drilling has “revolutionized” the United States’ oil and gas industry by allowing extraction of previously inaccessible oil and gas trapped in shale rock [1]. Although the United States has extracted shale gas in different states for several decades, the United Kingdom is in the early stages of developing its domestic shale gas resources, in the hopes of replicating the United States’ commercial success with the technologies [2, 3]. However, the extraction of shale gas using hydraulic fracturing and horizontal drilling poses potential risks to the environment and natural resources, human health, and communities and local livelihoods. Risks include contamination of water resources, air pollution, and induced seismic activity near shale gas operation sites. This paper examines the regulation of potential induced seismic activity in Oklahoma, USA, and Lancashire, UK, and concludes with recommendations for strengthening these protections.

AbstractConsiderable progress has been made over the past years to better understand the genetic nature and pathophysiology of brain AVM. For the actual review, a PubMed search was carried out regarding the embryology, inflammation, advanced imaging, and fluid dynamical modeling of brain AVM. Whole-genome sequencing clarified the genetic origin of sporadic and familial AVM to a large degree, although some open questions remain. Advanced MRI and DSA techniques allow for better segmentation of feeding arteries, nidus, and draining veins, as well as the deduction of hemodynamic parameters such as flow and pressure in the individual AVM compartments. Nonetheless, complete modeling of the intranidal flow structure by computed fluid dynamics (CFD) is not possible so far. Substantial progress has been made towards understanding the embryology of brain AVM. In contrast to arterial aneurysms, complete modeling of the intranidal flow and a thorough understanding of the mechanical properties of the AVM nidus are still lacking at the present time.

Alternative Solutions

The cement industry is highly energy-intensive, consuming approximately 7% of global industrial energy consumption each year. Improving production technology is a good strategy to reduce the energy needs of a cement plant. The market offers a wide variety of alternative solutions; besides, the literature already provides reviews of opportunities to improve energy efficiency in a cement plant. However, the technology is constantly developing, so the available alternatives may change within a few years. To keep the knowledge updated, investigating the current attractiveness of each solution is pivotal to analyze real companies. This article aims at describing the recent application in the Italian cement industry and the future perspectives of technologies. A sample of plant was investigated through the analysis of mandatory energy audit considering the type of interventions they have recently implemented, or they intend to implement. The outcome is a descriptive analysis, useful for companies willing to improve their sustainability. Results prove that solutions to reduce the energy consumption of auxiliary systems such as compressors, engines, and pumps are currently the most attractive opportunities. Moreover, the results prove that consulting sector experts enables the collection of updated ideas for improving technologies, thus giving valuable inputs to the scientific research.
