Rocks and fossils do not come with labels informing us of their age. They must be understood in light of their geologic context, and interpreted within a worldview. Unfortunately, my evolutionary colleagues are often so dominated by uniformitarian brainwashing they can't objectively understand young-Earth evidence. Nevertheless, some of the evidence is clear and open for all to see. One such cl...
Hand scaling is a physically demanding task responsible for numerous overexertion injuries in underground mining. Scaling requires the miner to use a long pry bar to remove loose rock, reducing the likelihood of rock fall injuries. The experiments described in this article simulated "rib" scaling (scaling a mine wall) from an elevated bucket to examine force generation and electromyographic res...
cutis laxa is rare and hetrogenous group of disorders related to abnormalities in elastic tissue. it may be autosomal recessive, autosomal dominant, x linked or acquired. acquired cutis laxa has developed after a febrile illness, inflammatory skin disease such a lupus eryhymatosis or erythema multiform, amyloidosis, hypersensitivity reaction to penicillin and in infants born from women who were...
Abstract Dams are built to contain water or mining tailings and provide several benefits society. The safety stability of these structures essential since eventual accidents can generate catastrophic damage. main cause ruptures is associated with abnormal seepage, which progress an internal erosion process. To assess the dams, periodic inspections carried out, typically include visual geotechni...
As a type of special geological body, soil-rock mixtures (SRMs) are widely found in nature and used civil engineering. Many structures, such as rockfill dams, highways tunnels, have SRMs building materials. Proper modeling is great importance to capture the complex behavior this heterogeneous material. In manuscript, simple constitutive model incorporating skeleton void ratio concept proposed f...
Plain concrete structures such as dams or retaining walls, as well as rock structures such as tunnels, caverns, excavations, and rock slopes, have commonly been designed by elastic-perfectly plastic analysis in which the tensile yield strength of the material is taken as zero. The paper analyzes the safety of this "notension" design in the light of the finiteness of the tensile strength of conc...
Dams on soft soils differ greatly in behavior when compared to rock foundations. Potential dam failures can occur due differential settlement. The total reduction Barnacle without PVD takes 17 years. Analysis of the use shows an increase shear strength dissipation pore stresses marked by safety figures. time needed achieve consolidation at least 80% is 180 days based finite element simulations....
