Stable Riprap Size for Open Channel Flows

Abstract : Riprap revetment is a widely used method for protecting the boundaries of erodible channels. Determining riprap size is an important step in the design process. Some of the existing methods for riprap sizing use the critical shear stress relations and logarithmic velocity laws to determine stable riprap size. Flume data used in this investigation show that use of a constant Shields coefficient in the critical shear stress relations is not valid for high relative roughness problems like riprap design. Neither are logarithmic velocity laws valid for high relative roughness problems. Another limitation of existing riprap sizing methods is lack of variation relative to the effects of gradation, thickness, or shape. Existing side slope relations used in the critical shear stress equation overestimate the decrease in stability that occurs when a particle is placed on a sloping bank. Comparison of velocity profiles over channel side slopes in straight and curved reaches shows that for the same average velocity over the toe of the side slope, the velocity and shear stress on the side slope are significantly higher on the outer bank of the curved channel. Depth and average velocity over the toe of the side slope are measured in straight and curved flume tests of riprap stability and are used to develop sizing relations for side slope riprap.
Development of Mix Design Nomograph for Polyethylene Terephthalate Fiber Concrete

The aim of this project was to develop of mix design nomograph for PFC that can be used for estimated the required compressive strength and splitting tensile strength with the required PET and water-cement-ratio.The fibers were prepared by using plastic granulator machine SLM 50 FY with size passing 10 mm and retained 5 mm sieve. Different volumes percentages of PET fibers with 0%, 0.5%, 1.0% and 1.5%, were introduced in concrete mixes. The specimens prepared for this study was cylinder concrete with 100 mm diameter and 200 mm height. The laboratory work for physical properties were focused on density and workability, meanwhile for mechanical properties were focused on compressive strength, splitting tensile strength and modulus of elasticity of PET fiber concrete (PFC). The experiment results indicate that the addition of PET fibers significantly decreased the compressive strength and splitting tensile, however the compressive strength still can be acceptable since achieved the mix design The nomograph developed can be used to estimate the desired compressive, splitting tensile strength as well as the modulus of elasticity (MOE).

Elusive active faults in a low strain rate region (Sicily, Italy): hints from a multidisciplinary land-to-sea approach 

<p>Low Strain Rate regions (LSRr), i.e., areas deforming at a 1 mm/yr rate or less, represent the most globally widespread areas that host important cities and high-vulnerable anthropogenic assets. The occurrence of infrequent but high-magnitude earthquakes suggests that identifying active structures in the LSRr is one of the primary challenges for both the scientific community and modern societies. </p><p>In such regions, one of the main issues in identifying active faults is the lack of useful outcrop data due to the anthropogenic and climate overprinting of the faults morphological signature. In this work, we propose a multidisciplinary approach designed to detect active geological structures and their related deformation. To test this approach, we selected as a natural laboratory an LSRr located between two major cities of Sicily (southern Italy). &#160; This area lies into the northern sector of the Apennine-Maghrebian fold and thrust belt and its offshore prolongation. </p><p>Our approach consists of quantitative morphotectonic, offshore and onshore tectonostratigraphic and GNSS joint analyses. The main achieved results are 1) the first evidence of active, shallow-sited, NNW-trending transpressive blind faults that extends partially offshore for about 30 km, which d&#233;collement levels located at about 3 and 1 km depth, respectively and their 3D model, 2) a morphotectonic evolution model, that represents where and how these geologic structures drove the landscape evolution of the study area. Finally, we highlight that only a multidisciplinary approach could be useful for detecting and parametrising active faults in slow deforming areas that cross the coastline physical limit. </p>

Use of Prefabrication to Minimize Construction Waste - A Case Study Approach

Abstract The increasing awareness of environmental impacts from construction waste has aroused much public concern. Some construction organizations have included waste management as one of the major functions of construction project management. As a result, some approaches and methods for managing construction waste have been developed. Replacing wet-trade activities with prefabrication is advocated as one of the waste minimization techniques on site. However, the adoption of prefabrication is mainly confined to public housing developments in Hong Kong. This paper uses four private building projects as case studies to demonstrate the effectiveness in the use of prefabrication to minimize construction waste in Hong Kong. The wastage levels of the four projects are compared with conventional cast in-situ methods under similar project natures and conditions. The hindrances and the future trend of adopting prefabrication in Hong Kong are also examined.
Second-order steady forces on floating bodies with forward speed

In this thesis a numerical solution is developed for the computation of the secondorder steady-forces acting on a ship with forward speed in the presence of incident waves under the Neumann-Kelvin flow assumption. The computation of these forces is achieved by integration of pressures over the ship hull and also through the use of momentum-flux relations, in the frequency domain. The solution of the first-order problem is obtained through the use of an existing time-domain computer program, where the computation of the velocities and the velocity potential in points in the fluid region using the source formulation was implemented as part of this work. Global and local quantities are Fourier-transformed to the frequency-domain, and the second-order steady-forces coming from first-order quantities computed. The boundary-value problem for the second-order Neumann-Kelvin steady potential is formulated and a solution attempted for the diffraction case under the low-speed assumption. The contribution coming from this second-order steady potential is found not to be significant for the computation of the total second-order steady force, in the cases analyzed. In connection with the momentum-flux approach, it can be seen that there will be no contribution coming from the second-order steady potential to the second-order steady horizontal forces. Results are presented for the Wigley hull, a hemisphere and a shallow circular cylinder. Comparisons are made with other theories and data from other publications. Thesis Supervisor: J.

N2O Fluxes and Related Processes of Denitrification in Acidified Soil

In North China, high levels of N fertilizer and irrigation water are used in fields, which cause considerable N2O fluxes via several pathways, especially anaerobic denitrification. Anaerobic denitrification is regarded as an important microbial process for N2O production in soils with a low O2 level and high N and labile C availability (the typical soil conditions caused by high levels of N fertilizer and irrigation water in the field). We conducted an anaerobic incubation experiment to determine the impact of soil acidification (with a series of soil pH levels, pH 6.2, pH 7.1, and pH 8.7) on N2O source partitioning with the addition of KNO3 and glucose. Natural abundance isotope techniques and gas inhibitor technique were applied to analyze the N2O flux derived from fungal denitrification and bacterial denitrification and its isotopocule characteristics emitted from soils after the addition of NO- 3 and glucose. A mapping approach was used to obtain further insight into the N2O production processes. Our findings confirmed that soil pH strongly controlled the N2O production and reduction rates of denitrification. Soil acidification significantly increased N2O emissions varied from 0.76 mg N kg-1 for natural soil (pH 8.7), to 1.88 mg N kg-1 for pH 7.1, and to 2.35 mg N kg-1 for pH 6.2, and had a blockage effect on the reduction of N2O to N2. The addition of carbon sources promoted complete denitrification. We assumed a higher contribution of fungal denitrification to N2O production compared to total N2O emission associated with acidified soil. A promotion of the contribution of fungal denitrification-derived N2O was indeed observed with decreasing pH, increasing from 0.28 mg N kg-1 for pH 8.7 to 0.94 mg N kg-1 for pH 6.2. The addition of glucose further increased the contribution of fungal denitrification to N2O production from 0.99 mg N kg-1 for pH 8.7 to 3.66 mg N kg-1 for pH 6.2. The mapping approach provided rational results for correcting N2O reduction compared with the acetylene inhibition method. The results calculated by both methods indicated a reasonably large contribution of fungal denitrification to total N2O production in acidified soils.

Perceived attributes of diffusion of innovation theory as predictors of Internet adoption among the faculty members of Imam Mohammed Bin Saud University

The Internet is the most common communication and research tool worldwide. Perusal of the World Wide Web quickly reveals the variety of information available. Internet adoption can be considered the late 20th century's most important event. In academic environments today, Internet use among faculty members has been widely expanded, with professors now integrating Internet technology into classroom activities. Imam Muhammad Bin Saud Islamic University (IMSU) is a pioneering public university in Saudi Arabia. Until recently, some faculty members at IMSU were unable to access the Internet through the university. It is important to study the effects of this delay on faculty members regarding research and academic activities. This study identified the statistically significant differences in demographic characteristics of Internet adopters and non-adopters among faculty members at IMSU, examined whether faculty members' perceptions of the Internet affected adoption, determined if the university administration's decisions impacted faulty members' decisions to adopt the Internet, identified factors motivating faculty members to adopt the Internet, identified obstacles influencing faculty members' decisions to use the Internet, and determined whether innovation characteristics as perceived by faculty members predicted Internet adoption. Using Rogers' diffusion of innovation theory, the influence of eight attributes were examined regarding Internet adoption among IMSU faculty members. Multiple regression and chi-square techniques were conducted to analyze the data and answer research questions. Statistically significant differences were identified among Internet adopters and non-adopters regarding gender, age, academic rank, discipline, and English proficiency. The data revealed 54.7% of IMSU faulty members used the Internet for research and academic activities twice a month or less, indicating a low Internet adoption rate. Statistically significant differences were noted among adopters and non-adopters relative to income level and English proficiency. Multiple regression analysis showed that all attributes of innovation individually predicted Internet adoption. The combination of all attributes indicated the model could predict Internet adoption among faculty.

In this paper, behavior of carbon steel, galvanized steel and aluminium exposed during 8 months in 21 Colombian sites of different aggressiveness was evaluated. Furthermore, using CLIMAT method, a bimonthly classification of atmospheres was made. Finally, corrosion rate of materials were correlated with atmospheric parameters measured in test sites as temperature, relative humidity, and sulphates and chlorides concentration.
Methionine and Threonine Requirements of Dutch Rabbits Fed under a Cecotrophy Prevention Program

It is suggested that the difference in body size between domestic-type rabbits and small pet-type rabbits results in different nutrient requirements. The nutritional requirements of pet rabbits have been assessed, although such assessments require evaluation throughout the rabbit life span. The present study was conducted under a cecotrophy prevention program with young and adult rabbits. Six male Dutch rabbits were housed individually in a dormitory-type cage, and they were randomly fed graded levels of dietary methionine and threonine, at ratios of 4:0, 3:1, 2:2, 1:3, and 0:4 mixed with two types of feed, 4:0 and 0:4. Four days after switching diets and 4 hrs after starting morning feeding, approximately one milliliter of blood was collected from the vein of the ear. Free amino acid concentrations in the plasma were determined with a high-speed amino acid analyzer. Plasma concentrations of methionine and threonine compared to dietary methionine and threonine levels are shown in young rabbits. The plasma concentration of methionine remained constant at a low level and then increased linearly. The intersection was estimated as 0.16 g/d. In the same manner, the intersection of the plasma threonine value was estimated as 0.27 g/d. These values were calculated as 0.27% and 0.47% of the diets, respectively. In the case of adult rabbits, the baseline was not obtained for dietary methionine and threonine levels. The methionine requirement was estimated as 0.11 g/d. The threonine requirement was estimated as 0.22 g/d. These values were calculated as 0.15% and 0.30% of the diets, respectively. In comparison with young and adult rabbits, both methionine and threonine showed a low baseline level in young rabbits, while their variations in plasma levels of adult rabbits were not determined. The requirement of both amino acids in young rabbits is higher than that in adult rabbits. The dietary values of both amino acids in young rabbits were also higher than those in adult rabbits. Small pet-type adult rabbits required lower amino acid levels than domestic-type rabbits.
