Research ArticleOpen accessIn the abstractThe Gravity Field of a CubeJames Michael Chappell, Mark John Chappell, Azhar Iqbal, Derek AbbottWe calculate the Newtonian gravitational potential and field of a cubic, homogeneous asteroid and we apply it to the orbit of possible satellites. Large astronomical objects such as stars or planets, naturally tend to form spherical shapes due to the dominance of the gravitational forces, but as a thought experiment, we consider the properties of a planet in the form … …Physics International, Vol. 3, Issue 2 · 27 Mar 2013 · 15,337 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Transboundary Movement of Hazardous Waste: A Contribution to Improve the Present Technical-Judicial ModelGiancarlo Carosso, Cesare Luceri, Pierpaolo OresteThe expression &#34the transboundary movement of hazardous waste&#34 refers, from the technical point of view, to a series of phases that begin with the creation of a hazardous waste and includes its identification according to international, regional and national standards, its delivery to specialized companies and its movement from the exporting country to the importing country; these phases end with … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 13 Jul 2012 · 7,156 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnvironmental and Safety Accidents Related to Blasting OperationLazar Kricak, Vladislav Kecojevic, Ivan Jankovic et al.The blasting process remains a potential source of numerous environmental and safety accidents. The majority of these accidents were contributed to the flyrock and lack of blast area security. A field-scale investigation related to flyrock accident was conducted in an andesite quarry where rocks up to 50 cm in diameter were propelled almost 300 m from the center of blasting … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 8,904 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSoil-moisture Retention Characteristics of Earth Materials in the Weathering Profile over a Porphyritic Biotite GraniteJohn Kuna RajProblem statement: Three broad morphological zones and several sub-zones were differentiated within the weathering profile based on variations in earth materials and the degree of preservation of original bedrock minerals, textures and structures. Approach: The topmost Zone I (Grade 6) is some 12 m thick and comprises completely weathered bedrock materials (mainly a stiff, clayey sand) with indistinct relict bedrock … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 9,474 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Air Pollution on Ozone Layer Thickness in Troposphere over the State of KuwaitH. O. Al Jeran, A. R. KhanTroposphere ozone layer acts as a shield against all ultraviolet radiation approaching the planet Earth through absorption. It was noticed in mid 80s that ozone layer has thinned on the poles of the planet due to release of man-made substances commonly known as Ozone Depleting Substances, (ODS) into its atmosphere. The consequences of this change are adverse as the harmful … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 19,492 accessesView PDF Cite

Research ArticleOpen accessIn the abstractApplication of RNA-DNA Duplex Base Triplets to Antisense DrugsJie Yang, Yao Leng, Ju BaoSixty-four sets of three-dimensional models of RNA-DNA duplex base triplets were constructed based on codons by homology modeling method using software InsightII on Indigo workstation, which should be helpful for the study of RNA-DNA annealing, the basis of nucleic acids interactions and some peculiar motifs for design antisense oligonucleotides. Our research result reveal that the energies (such as E, Ec, … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,534 accessesView PDF Cite
