Earthen materials show interesting environmental advantages when used to build [1]. These materials are becoming increasingly important in the context of the modern desire of construction materials which are less highly processed and have low toxicity [2][3][4]. Nowadays, there are several available techniques where these materials can be used with structural purposes, namely as earth blocks (adobe), compressed earth blocks (CEB), rammed earth and cob [5] but the lack of scientific data and lack of experience by the mainstream construction industry in using these materials remain barriers to be overcome [6]. As earth is a heavy, low strength material, its use in construction is expected to essentially be limited to single storey walls and ground floors [7]. Earthen masonry shows low values of strength in compression and in tension and a resulting general brittle failure [8]. Therefore, an improvement of the final behaviour may be reached adding cement to the soil material and obtaining stabilized earthen blocks. In the last decade several studies were carried to exploit the potentiality of cement stabilized earthen materials, as earth block masonry [9][10][11][12][13][14][15][16] or rammed earth [17][18][19][20][21]. Earthen blocks performance may be improved adding cement in the mixture; the use of…

Case Analysis 1. What are the facts in the case? John is the chief seismologist at one of the leading research facilities in North America who holds a P.H.D from one of the most prestigious university in the country. John has developed a method for predicting earthquake with 80% accuracy rate. From his investigation, he discovered that there is a 80% chance that an earthquake will occur with a magnitude of 7.3 in one of the four fault lines in southern california within two days. While three…

Is the Hayward Fault line moving the earth’s surface, and if so where is the evidence to prove it? There are various methods to prove that the Hayward Fault is creeping, and the evidence is viewable such as offset curbsides, building that are being torn apart, and cracks in the earth’s surface. The Hayward Fault is a strike-slip fault meaning it moves up, and down, thus giving us multiple locations in which the surface is affected. There are five different locations that I chose on the Hayward…

chosen from Problems for Biomedical Fluid Mechanics and Transport Phenomena section 8, because of my interest in biomedical engineering. How the body works on the most fundamental chemical and physical levels is something that has always fascinated me. This problem, and others in the section on blood flow, offered me a chance to delve deeper into how the body works as well as transport phenomena. The problem gave us a solved velocity distribution for flow of a Casson fluid in a very narrow…

point anchors which, when set in the predrilled hole, are then tensioned to secure an anchoring device which will pull against the keyhole plate and the anchor point to secure the surface to a more competent layer. The mechanical bolts have more parts to go wrong, as well as a higher cost. The mechanical anchors have though shown to be a very reliable way to pull the unstable layer back to the competent layer. The forces are not being applied directly to the sides of the hole in its entirety,…

hugely visible. The amount of travelled distance and shear that the glass had possibly increase along the way to the bottom the cylinder. The Steel Ball for Turbo Flo and the Glass Ball the SAE 30 had a large but moderate error difference. This might be because a property difference in steel and glass ball used for the experiment was altered in its composition. The amount of error from Glass & Steel balls for Turbo Flo was 20.7%% & 40.8% and for SAE was 48.13% & 31.5%. Overall there was not too…

1.1. Mechanical properties of CP/CNF and CP/CNF/ZIF-67 1.1.1. Stress–strain curves The stress–strain curves and the effects of CNF dosage on the tensile strength, elastic modulus, and elongation at break of CP/CNF and CP/CNF/ZIF-67 are shown in Fig. 3 and Tables S1–S4. As shown in Fig. 3(A) and Table S1, the tensile strength, elastic modulus, and elongation at break of neat CP is 7.37 MPa, 996 MPa, and 3.07%, respectively. After coating and crosslinking with CNFs, the mechanical properties of…

Vertical dimension (VD) defined in the Glossary of Prosthodontic Terms as "The distance between two selected anatomic or marked points”. Occlusal vertical dimension (OVD) defined as "The distance between two selected anatomic points when in maximal inter-cuspal position”.(1) The OVD is determined by the repetitive contracted length of the elevator muscles which sets the jaw-to-jaw relationship.(2) During growth and development OVD affected by three factors: Growth of the ramus, gonial angle of…

dynamics problem, the two most important equations needed to be solved are the continuity equation: ∂/(∂x_j ) (ρ . u_j )=0 (3.1) and momentum equation: ∂/(∂x_j ) (ρ . u_j . u_i - τ_ij )=∂p/(∂x_j )+ S_i (3.2) In these two equations (3.1) and (3.2) the following notations were used: xj Cartesian Coordinates (j = 1,2,3) uj absolute velocity components in the direction of xj p Piezometric pressure = ps-o . g . xm. Here ps is static pressure, o is the reference density, g is the gravity…
