The natural nighttime light environment of the earth has been significantly transformed by human activities. Such “light pollution” has a profound influence on ecosystems. Protected areas (PAs) play key ecological functions and are only effective at low light pollution levels or without any light pollution. In China, with rapid population growth and high urbanization rates, light pollution in P...

Municipal waste management is still a significant problem for solid issues in Indonesia. Only 60 to 70% of the generated disposed landfills, rest dispersed different areas. The potential leachate pollution, greenhouse gases, and non-renewable natural resources can occur due municipal problems not being optimal. needs holistic concept that would include upstream downstream stages. This paper com...

Cut-elimination is one of the most important techniques in proof theory. Roughly speaking, eliminating cuts from a proof generates a new proof without lemmas, which essentially consists of the syntactic material of the proven theorem. Traditionally cutelimination served the purpose to show consistency of calculi and thus played a central role in metamathematics. In this traditional context the ...

Newton, in an unauthorized textbook, described a process for solving simultaneous equations that later authors applied specifically to linear equations. This method — that Newton did not want to publish, that Euler did not recommend, that Legendre called “ordinary,” and that Gauss called “common” — is now named after Gauss: “Gaussian” elimination. (One suspects, he would not be amused.) Gauss’s...

it has been estimated that nearly half of the world’s population is at the risk of contracting malaria with sub saharan africa being the most risky area. the existing frontline malaria control interventions are not only expensive but also become ineffective owing to the emergence of insecticide and drug resistance. it calls for an innovative approach in terms of potential and reliable vaccine a...

Municipal wastewater treatment to recycling level is an important means conserve water resources. Untreated leads a reduction in per capita availability of and increase environmental pollution. Therefore, the current study, filtration process based on Typha Angustifolia planted vertical flow wetland Rice husk (VFCW) combination with catalytic ozonation Cobalt loaded zeotype catalyst was used fo...

Propene dissociation channels were characterized by ab initio CCSD(T)/6-311++g(d,p) calculations. Inthis work the detailed mechanism of propene dissociation to C2H4+CH2, C2H2+H+CH3, C2H2+CH4 andC3H3+H2+H have been investigated. According to our calculations, ten fragments can be classified intofive dissociated channels. Our results point out that two mechanisms come into play in the H2 eliminat...

Pollution in P2P file sharing occurs when a large number of decoy files are injected into the P2P system. Since peers “serve” each other in the P2P file sharing system, it is obvious that pollution dynamics are closely related to user behavior. Therefore, we first conduct a human subject study to investigate user behavior. We identify the factors that are key to model user behavior, e.g., coope...
