Damage Monitoring of Dry and Saturated Rocks Using Piezo Transducers
Authors: Negi P. , Chakraborty T. , Bhalla S. 
Published: December 2016

Abstract
This paper explores the possibility of using the electro-mechanical impedance (EMI) technique for structural health monitoring (SHM) of underground rock structures. The underground structures are complex in design and require continuous inspection for their maintenance. However, some of the underground areas are inaccessible for the inspection team or might warrant a special clearing arrangement, leaving the structure out of service. The complexity in their design, their construction, and the conditions encountered during service life necessitate the deployment of a dedicated SHM system. Sometimes the stress ratio in rock because of overburden stress and tectonic activities may reach a high value exceeding threshold, which may lead to rock bursts and subsequent failure of the structure. The SHM technique becomes important for underground infrastructure to enable timely detection of the damage caused by any anticipated or unanticipated loads. In the present study, rock specimens have been tested in a laboratory environment under saturated, as well as dry, conditions, under pre-loaded stress conditions by applying continuous quasi-static loading, so as to simulate the near-real-life underground conditions. The EMI technique is used for damage monitoring. The vibrations generated by the actuation of lead zirconate titanate (PZT) patch are sensed by the same PZT patch and recorded in the form of conductance and susceptance signatures. The signatures have been quantified using root-mean-square-deviation (RMSD) method. The test results clearly establish the potential of the EMI technique in detecting and quantifying load-induced damage in dry, as well as saturated, conditions in the underground structures, opening avenues for applications in real-life situations.
Effects of Cement, Different Bentonite, and Aggregates on Plastic Concrete in Besh-Ghardash Dam, Iran
Authors: Kazemian S. , Ghareh S. 
Published: December 2016

Abstract
Besh-Ghardash Dam is located 5 km from Bojnourd city in North Khorasan Province, Iran. This research investigated the use of a plastic concrete. Because of a lack of specified standards for such materials, there is a serious need to evaluate effects from the amount and the quality of concrete aggregates (fine and coarse gravel and sand), cement, water, and bentonite on mechanical properties. This study looked at the effect of the ratio of mixture proportions and cement, as well as the materials' quality, such as the type of bentonite on compressive strength, modulus of elasticity, and permeability of plastic concrete. The results showed that by decreasing the ratio of term activity in bentonite reduced compressive strength, because of an increase in free water when other components were held stable. The effect of the cement has a direct effect on elastic modulus, as well as the compressibility of plastic concretes. The results showed that there is a direct effect of the cement on the permeability of such plastic concrete.
Seismic Analysis of Municipal Solid Waste Dumps: Site Specific Case Studies From Delhi, India
Authors: Ramaiah B. J. , Ramana G. V. 
Published: December 2016

Abstract
Site specific seismic analysis is necessary for reliable assessment of performance of municipal solid waste (MSW) dump sites/landfills due to the highly heterogeneous nature of waste mass. This paper presented the results of one-dimensional site specific seismic studies performed for two old and tall MSW dump sites in Delhi, India. Unit weight profile and dynamic properties of emplaced MSW at these two sites, evaluated from field and large scale laboratory tests, were utilized in seismic analysis. Synthetically generated strong ground motions using finite source model and specific barrier model, with appropriate seismological parameters for the Delhi region, were used. It is observed that the ground motion amplification potential of MSW for low intensity events in the present study compared well with that reported for Operating Industries Inc. landfill in California, which is instrumented with strong ground motion recording stations. Amplification observed in the present study can be useful for the design of a final cover system during the closure of the dump sites studied herein. In addition, results in terms of the maximum horizontal equivalent acceleration for base-sliding case were in agreement with those reported in the literature, and can be used for preliminary estimates for the design of liner system of new engineered MSW landfills in Delhi.
Comprehensive Analysis of Performance Data for Energized Vessel Sealing Devices
Authors: Pappas J. , Roweton S. , Kurtenbach J. , Dunne J. B. 
Published: December 2016

Abstract
Burst pressure and thermal spread are two key performance characteristics associated with the development of safe and effective energy-based vessel sealing and tissue transection devices. A thorough literature review revealed that a large percentage of studies describing assessments of burst pressure or thermal spread, or both, used univariate, single-factor inferential statistics as the primary source of analysis, with the Student’s t-test and one-way ANOVA being the most prevalent methods. In addition, there were only two examples of studies that discussed the approach for handling two correlated halves of a vessel seal created by vessel sealing and dividing devices. Use of analysis methods such as those described can result in a problematic mixing of known and unknown variability, as vessel diameter, specific device used, test gauge, particular tissue properties, and several other factors potentially have an impact on burst and thermal spread measurements. The consequences of this are potential confounding, a lack of sensitivity when comparing groups, and a general inability to better understand the factors and interactions involved with optimizing overall seal performance. This paper describes a study evaluating the performance of four energy-based vessel sealing devices, and it outlines the comprehensive method used for analyzing burst pressure and thermal spread measurements obtained from these devices. This approach incorporates covariates into the analysis, increasing overall study power and facilitating an enhanced understanding of experimental noise factors. Higher sensitivity in the analysis and identification of key experimental factors contributing to variability allows the utilization of an evidence-based approach to continuously improve test and analysis methods, and complete successive design iterations for the development of consistently safe and effective vessel sealing and tissue transection devices. Results from this comprehensive analysis method have been included in multiple domestic and international regulatory submissions.
Effect of Unit Weight on Porosity and Consolidation Characteristics of Expansive Clays

Published: December 2016

Abstract
This study investigated the relationship between pore characteristics and unit weight of clayey soils. This relationship was particularly important in case of expansive soils, as the pore characteristics determine moisture flux boundaries, which in turn represent volume change behavior. Current research tried to evaluate the effect of compaction unit weight on the pore size and pore volume along with consolidation and swell characteristics on two expansive clays from semi-arid environment. The two selected clays represent soils with different degrees of expansion, particle size and mineralogy. Pore size characterization for these two soils was performed using Mercury Intrusion Porosimetry, while swell and consolidation characteristics were determined using a conventional oedometer test. Samples for both tests were compacted at different unit weights including, 100, 95, 90, 80, 75, and 70 % of maximum dry unit weight (MDUW) obtained from standard proctor. The compaction water content was kept constant for all unit weight levels. Both pore volume and pore size distribution was analyzed with varying unit weight characteristics and particle sizes. In addition, swell strains and compression indices were studied with varying unit weight of compacted specimens. It was observed that, in the case of samples compacted at 100 % MDUW, about 50 % of the pores were larger than 0.1μm, and this value increased with reduction in unit weight. Current research is of practical importance, especially in the wake of microbial treatments for clayey soils where the passage of microbes depends on the pore size and more specifically pore throat size.

Let $A_{1}$ and $A_{2}$ be fixed sets of gaussian integers. We denote by $\tau_{A_{1}, A_{2}}(\omega)$ the number of representations of $\omega$ in form $\omega=\alpha\beta$, where $\alpha \in A_{1}, \beta \in A_{2}$. We construct the asymptotical formula for summatory function $\tau_{A_{1}, A_{2}}(\omega)$ in case, when $\omega$ lie in the arithmetic progression, $A_{1}$ is a fixed sector of complex plane, $A_{2}=\mathbb{Z}[i]$.

Published: December 2016

This case is to be used as an understanding of the causalities that result from the disarray of future direction, impeding chaos and dysfunctional status to an organization when its “Vision” is lost. The case presents the financial impact when the impetus of a strategy implementation incurs a major disruption due to the loss of its inspirational and transformational leader. The joint venture had completed its internal structuring, communicated internally its mission and product and services, acquired and/or spent many millions of dollars in operational and capital infra-structure prior to its premier into the marketplace. The case describes the environment of disillusion, political in-fighting, and personal and selfish objectives that resulted in the death of the joint venture. Analysis of the case should address the organizational and managerial behavior that should have been the practical application and situation in order for the continual implementation of the organization and benefit to the market place and all stakeholders.
Temporal Variation in the Activity of Echolocating Bat Community in Amurum Reserve North Central Nigeria
Authors: Emmanuel C. Nwankwo , Manu Shiiwua A. 
Published: December 2016

<em>The effect of temporal variation on activity of the echolocating bat community was determined in four habitat types in and around Amurum Forest Reserve: (i) gallery forest, (ii) savannah, (iii) rocky outcrop, and (iv) farmland. Using transect-based acoustic surveys in the various habitats, bat activity was estimated based on the recorded number of bat passes per minute of echolocation recordings from the field survey grouped into hours after dusk (19:00-23:00) and hours before dawn (02:00-06:00). Bat activity was significantly higher in hours after sunset than hours before sunrise. Activities did not vary significantly in the farmland between hours after sunset and hours before sunrise. In the gallery forest both times of the night had significant impact on bat activity, while in savannah and rocky outcrop habitats only hours after sunset did have significant effect on bat activity. The farmland showed a different trend by hours before sunset having a significant impact on bat activity. Echolocating bat communities in Amurum Reserve are more active during the hours after sunset than hours before sunrise. We recommend hours after sunset as more suitable period for surveying echolocating bat species through acoustic methods. The managements of reserves may do well in avoiding human activities in the protected areas during hours after sunset for maximum performance of the echolocating bat communities in the reserves. </em>

Published: December 2016

Environmental parameters influence the productivity and abundance of fish in marine ecosystems. In this study, we attempted to analyse the relationship between environmental parameters and abundance of fish in trawling grounds in south-eastern Arabian Sea along the coast of Karnataka. Among the 85 species of finfishes and shellfishes caught in the trawling grounds, 41 finfish species, 24 crustaceans, 18 molluscs and two echinoderms were recorded. Seasonal differences were seen in biomass with the highest biomass during the post-monsoon period (October-January). Water temperature and nutrients were the key contributing factors of seasonal differences in the biotic communities studied. Season specific diagnostic species were identified using SIMPER analysis. Squilla which formed the major prey item of most of the demersal fishes dominated (>40%) coastal grounds throughout all seasons. This could be considered as a fishery indicator of the region. The dominance and abundance of copepods was found to be influenced by sea surface temperature (SST) and nutrients. The results of the study have implications on the fishery, knowledge on environmental factors influencing the abundance and importance of non-commercial species in sustaining the fishery in the region.
