Liquefied natural gas (LNG) has become an important part in the energy industry on account of its high density, low carbon emission, and convenient transportation. In recent years, with discovery unconventional resources, situation world’s liquefaction plants using conventional as feedstock is changing. Unlike traditional LNG plants, processes require special considerations design manufacturing...
transformationprocessesdebate ontheinteractionsbetween archaeological artifacts and structures based on their natural and cultural environments. these processes provide a good picture about the site formation after its creation until now. recognition of these processes and their context help archaeologists to interpret archaeological data in an appropriate way. in this paper i would argue abou...
What is in store for the guppy? Variation is essential to understanding the genetics underlying biological processes. The guppy provides a huge amount of natural variation that can be studied genetically. This variation has not been produced by mutagenesis screens, but instead has been shaped by natural selection. Thus, combined with emerging genomic resources, the guppy is an ideal organism fo...
The discovery of new basic compounds holds the key for advancing material sciences. We have focused on the identification and characterization of natural key compounds that control biologically and physiologically intriguing phenomena. The discovery of new bioactive molecules, facilitated by a deeper understanding of nature, should advance our knowledge of biological processes and lead to new s...
In this paper, we first give a short discussion of the macroevolution viewing life as information-directed, complex, dynamic systems. On this basis, we give our explanation of the origin of life and discuss the top-down evolution of molecules, proteins, and macroevolution. We discuss these subjects according to our new holistic biological paradigm. In view of this, we discuss the macroevolution...
BACKGROUND Knowledge about how change the importance of soil seed bank and relationship between seed mass and abundance during vegetation succession is crucial for understanding vegetation dynamics. Many studies have been conducted, but their ecological mechanisms of community assembly are not fully understood. METHODOLOGY We examined the seasonal dynamics of the vegetation and soil seed bank...
