Plate tectonics

In the first article, “Earthquake Kills Scores in Mexico,” we find some background on how Mexico city was destroyed by an 8.1 magnitude earthquake. The tragedy made the first page of the New York Times on September 20, a day after the disaster happened. According to the article, more than 40 buildings collapsed throughout the city. Many people were trapped under the rubble of the fallen buildings. Mexico was first built on top of a lake. This makes for a slightly different urban structure than…

powerful eruption of a volcano in the past 500 years thats has struck Indonesia. The creation and eruption of Mount Tambora can be contributed to the interaction between the Indo-Australian and Eurasian plate. The plate with higher density subducts under the plate with lower density. As the plate goes under, it melts and forms a magma plume and composite cone volcano. The eruption of Mount Tambora sent molten rock more than 40 kilometres high and blew out a cloud of ash that covered a million…

Neotectonics in Australia. Abstract The cratons of the world that are located at a distance from plate boundaries are considered to be stable tectonically, but in real sense, they are subjected to regular disturbance that are less persistence and also of lesser magnitude than those that lies near plate boundaries, Nonetheless their manifestation can be seen in landscape. Neotectonics are post Miocene tectonic deformation on the earth surface. Its evidence takes expression in form of recent…

Northwest was hit by a 45 second, 6.8 magnitude intraslab earthquake called the Nisqually or “The Ash Wednesday” earthquake. The Nisqually earthquake occurred when the Juan de Fuca plate subducted under the North American plate, this quickly released the built up strain. This was caused by mineral changes as the plate moved farther into the mantle. The Nisqually earthquake hit the southern end of Puget Sound causing damage to the ports of Seattle and Tacoma. Most of the property damage…

transition from stereotomic to tectonic architectural concepts. This transition was initially responding to exigencies, however poetic functional forms evolved which, in Australia fashioned a variety of uniquely Australian types of Architecture. These Australian types also differed depending on the local climate, with one well-known vernacular Australian architectural type, the Queenslander, developing from several existing styles, and adapted to Queensland’s climate. Tectonic aspects of the…

the incubation of the mEndo plate for 24 hours it is perceptible the grown of E. coli colonies across the plate. The results of this method are shown in the figure 4. As it was used mEndo, just the E. coli colonies form bright green colonies with a golden or green sheen - and it is evident in the plate, and the colonies which are not within of this specific characteristic are not considered E. coli. Next, it is necessary to count the E. coli colonies that grown in the plate. In this experiment,…

Jared Diamond explores the history of the world from a unique view. An ecologist and evolutionary biologist himself, he was not particularly trained to examine the world in the way an anthropologist would. This book, Guns, Germs, and Steel: The Fates of Human Society, delves into the known world and societies within it, at least as of 1997. Diamond wanted to uncover why history unfolded differently on the different continents over the last 13 thousand years, but more importantly he wanted to…

The SH-SY5Y neuroblastoma cell line was procured from National Centre for Cell Sciences, India and maintained in (DMEM) (Sigma Aldrich, USA) and Ham 's F12 nutrient mixture (F12) (Sigma Aldrich, USA) in 1:1 ratio. The medium was supplemented with 2 mmol L-glutamine (HiMedia, India), 10% (v/v) heat inactivated fetal bovine serum (FBS) (Hyclone Laboratories, Logan, UT) and 1% antibiotics (penicillin/streptomycin). Cells were cultured at 37 ºC in a humidified CO2 ¬incubator containing 5% CO2 and…

Methods 1. Treatment of barley with endophyte. • Five types of Barley were treated with the endophyte Pseudomonas fluorescens L321. • They were innoculated with the seed coating mixture ( 4% sodium alginate and 1% skimmed milk powder) without the bacteria. The bacteria were grown up overnight in LB broth supplemented with 3% trehalose (400ml per strain) , centrifuged and then added and then resuspended in the coating mixture. • 30ml of inoculant mixture was then added to 1kg of seed in a…

method using 96-well micro-titer plates. To each 50 μL of the antibacterial agent dilution, 50 μL of adjusted bacterial concentration inoculum (5 × 105 CFU/mL) were added in the 96-well micro-titer plates, the growth control wells contained MH broth medium with tested bacterial concentrations and sterility control wells contained only MH broth medium as shown in figure 2. The plates were then covered to ensure that the bacteria were not dehydrated. Then the plates were incubated at 37°C for 18…
