Estimation of deep infiltration in unsaturated limestone environments using cave lidar and drip count data

Abstract. Limestone aeolianites constitute karstic aquifers covering much of the western and southern Australian coastal fringe. They are a key groundwater resource for a range of industries such as winery and tourism, and provide important ecosystem services such as habitat for stygofauna. Moreover, recharge estimation is important for understanding the water cycle, for contaminant transport, for water management, and for stalagmite-based paleoclimate reconstructions. Caves offer a natural inception point to observe both the long-term groundwater recharge and the preferential movement of water through the unsaturated zone of such limestone. With the availability of automated drip rate logging systems and remote sensing techniques, it is now possible to deploy the combination of these methods for larger-scale studies of infiltration processes within a cave. In this study, we utilize a spatial survey of automated cave drip monitoring in two large chambers of Golgotha Cave, south-western Western Australia (SWWA), with the aim of better understanding infiltration water movement and the relationship between infiltration, stalactite morphology, and unsaturated zone recharge. By applying morphological analysis of ceiling features from Terrestrial LiDAR (T-LiDAR) data, coupled with drip time series and climate data from 2012 to 2014, we demonstrate the nature of the relationships between infiltration through fractures in the limestone and unsaturated zone recharge. Similarities between drip rate time series are interpreted in terms of flow patterns, cave chamber morphology, and lithology. Moreover, we develop a new technique to estimate recharge in large-scale caves, engaging flow classification to determine the cave ceiling area covered by each flow category and drip data for the entire observation period, to calculate the total volume of cave discharge. This new technique can be applied to other cave sites to identify highly focussed areas of recharge and can help to better estimate the total recharge volume.
Co-evolution of demand and supply under competition

In this paper, we derive strategies to enforce dominance in a business-to-consumer market with heterogeneous, competing products, while the market segmentation evolves through interaction of demand and supply. By using evolutionary economic notions, we extend operations management studies on manufacturing facing demand diffusion. We arrive at a synthesis of a Forrester delay manufacturing model and a technology substitution-diffusion model and show that the actual operationalization of product attractiveness, reflecting what consumers deem important, as well as the responsiveness of production capacity scaling greatly determine the market dynamics and asymptotic outcome. We obtain analytic results on absolute dominance in case of the constant inherent attractiveness of products, say technical performance, and numerical results on instability and quasi-stability in case of more encompassing definitions of attractiveness involving price and service level. We conclude, in general, that in establishing market dominance, firms should focus on timely entry to capture first-buyers, high responsiveness and predatory pricing. Scale advantages and resilience through responsiveness are essential in obtaining and subsequently retaining the market share when other firms already provide or are about to enter with technically superior products. We also hint on how to extend our model to study several other issues on industry dynamics.
Extreme localized exhumation at syntaxes initiated by subduction geometry

Some of the highest and most localized rates of lithospheric deformation in the world are observed at the transition between adjacent plate boundary subduction segments. The initiating perturbation of this deformation has long been attributed to vigorous erosional processes as observed at Nanga Parbat and Namche Barwa in the Himalaya and at Mount St. Elias in Alaska. However, an erosion‐dominated mechanism ignores the 3‐D geometry of curved subducting plates. Here we present an alternative explanation for rapid exhumation at these locations based on the 3‐D thermomechanical evolution of collisions between plates with nonplanar geometries. Comparison of model predictions with existing data reproduces the defining characteristics of these mountains and offers an explanation for their spatial correlation with arc termini. These results demonstrate a “bottom‐up” tectonic rather than “top‐down” erosional initiation of feedbacks between erosion and tectonic deformation; hence, the importance of 3‐D subduction geometry.
Some aspects of strongly heated turbulent boundary layer flow

Rayleigh scattering and laser Doppler velocimetry were used to study density and velocity statistics in a strongly heated turbulent boundary layer with free stream velocity U∞ = 19 m/sec and wall temperature Tw = 1100 °K. Mean and rms fluctuation profiles of density and velocity were found to be self‐preserving, and the velocity profiles were not significantly affected by wall heating. Streamwise velocity profiles, and mean temperature profiles deduced from density data were compared with Townsend’s self‐preserving analysis. It was found that wall heating caused a reduction in Reynolds stress within the thermal layer. This phenomenon was explained with reference to the thermal layer structures observed in high speed schlieren movies.
The Making of a ‘Colony’ in Karachi and the Politics of Regularisation

Around half of Karachi’s population resides in localities that started life as unplanned settlements, which acquired different levels of security from eviction. This paper examines the relationship between demand-making by unplanned settlements and urban political process. It interprets the gradual transformation of a cluster originally on the geographic and social periphery of the city into a regularised colony through the lens of collective action. The diverse roles of migration, mobilisation, and collective identity which we find in individual stories and community histories, capture a range of processes and experiences within Karachi’s wide margin. The politics of regularisation thus offers a critical perspective on the dynamics of urban democracy.
EXPLORING AN ACADEMIC WRITING CLASS IN AN INDONESIAN UNIVERSITY CONTEXT

Academic writing class in any Indonesian university context plays an important role for the students to cope with written academic assignments. This paper explores the perceptions of university students regarding their academic writing class. The participants were students of a private university in Pontianak, West Kalimantan, Indonesia. They were selected based on their achievements in the class and their genders. The data collection made use of interviews which were conducted immediately after the completion of the class. Individual interviews were conducted with six participants with three of them were male and the other three were female who were mainly regarded as medium achievers. The interview sessions were audio taped. The data then transcribed and analysed thematically. The discussion of the findings showed that the students gained benefits from the class through the applications of genre-based approach teaching stages, explicit teaching, and group work, which enabled the lecturer to develop the students' academic writing, critical thinking, and characters. Still, several limitations were also identified. Suggestions were offered by the participants for the betterment of the academic writing class.
Perceived Relationship Between Leadership Style and Organizational Commitment at Defence University

The aim of this study was to examine perceived relationship between leadership style and organizational commitment at Defence University. A correlational descriptive survey design was used in the study. The sample respondents consisted of 153 employees selected using stratified random, simple random and availability samplings. Multifactor Leadership Questionnaire developed by Bass and Avolio (1995) and Organizational Commitment Questionnaire developed by Allen and Meyer (1990) were used to gather data. Then data were processed using a computer program, SPSS 20, and analysed using inferential statistics such as t-test and Pearson’s Correlation Coefficient(r). The results unveiled that transactional and laissez-faire styles were dominantly used while continuance commitment was the dominant component of organizational commitment. The correlation analysis further revealed that there was a moderate, positive and significant relationship between transformational leadership behaviours of leaders with all dimensions of organizational commitment. Transactional leadership behaviour was perceived to have a weak but significant and positive relationship with all dimensions of organizational commitment, and no significant correlation was observed between laissez-faire leadership behaviour and organizational commitment. It was concluded that it would be difficult to achieve the overall goals of the university with the existing leadership style being used and employees’ commitment in the university. Thus, the study suggested different approaches to improve the existing leadership skills and employees’ organizational commitment in the university under study. Keywords: Leadership style, leadership behaviour, organizational behaviour, Organizational commitment
Numerical data processing from a laser flash experiment on thin graphite layer

In this paper, the methodology for determination of the out-of-plane thermal diffusivity (TD) of a thin graphite layer deposited onto a substrate of known properties is presented. The developed methodology resulted in combined experimental-numerical procedure enabling investigation of the properties of thin layer deposits. The procedure involves the experimental data acquisition during the laser flash tests, and next the numerical processing of the collected data using the heat conduction problem solution and the nonlinear least square parameter identification approach. Two last steps produce a certain inverse heat conduction problem that is formulated and numerically solved for a three-layer specimen. The procedure has been successfully tested while processing the real experimental data from investigation of flake graphite layers. This proved the effectiveness of the methodology in providing quantitative data on the TD of thin layers of relatively poor conductors deposited onto a highly conductive substrate.
INVESTIGATION OF ACCURATE METHOD IN 3-D POSITION USING CORS-NET IN ISTANBUL

In this study, for Istanbul, there are two Cors Networks (Cors-TR, Iski Cors) providing Virtual Reference Station (VRS), and Flachen Korrektur Parameter (FKP), corrections to rover receiver for determining 3-D positions in real time by Global Positioning System (GPS). To determine which method (or technique) provides accurate method for position fixing, a test network consisting of 49 stations was set up in Yildiz Technical University Davudpasa Campus. The coordinates of the stations in the test network were determined by conventional geodetic, classical RTK, VRS and FKP methods serviced by both Cors-TR and Iski Cors. The results were compared to the coordinates by the conventional method by using total station. The results showed a complex structure as the accuracy differs from one component to another such as in horizontal coordinates, Y components by CorsTR_VRS and Cors_TR_ FKP showed ‘best’ results while the same technique provided X components consistent accuracy with the Y component but less accurate than by real time kinematic (RTK). In vertical components, of all the techniques used for the h components, CorsTR_VRS showed ‘best’ accuracy with three outliers.
A Review on Nanoparticle Addition in Base Fluid for Improvement of Biodegradable Ester-based Drilling Fluid Properties

Nanotechnology is increasingly capturing the attention of material researchers as this technology pushes the limits and boundaries of the pure material itself. Nanofluids usually contain enhanced physical properties such as thermal conductivity and electrical conductivity. The incorporation of such technology can be shifted to the oil and gas industry, especially areas relating to drilling fluid. However, most drilling muds have detrimental effects such as environmental pollution, low degradation of drilling mud and strenuous post-treatment. Thus, the need for the production of a biodegradable drilling fluid is emphasized. However, current limitations imposed on the said drilling fluid restrict its usage on conventional drilling operations. This paper aims to review the effects of addition of powder nanoparticles into base fluid to achieve required criterions of industrial drilling fluid. Generally, the addition of nanoparticles into base fluids will result in better thermophysical properties such as thermal conductivity and convective heat transfer coefficients. The enhancement of thermophysical properties in drilling operations are highly desirable as heat generated from the friction between of drilling bit and the wellbore can be circulated at a higher rate. The addition of nanoparticles also results in changes in electrical conductivity and viscosity of the base fluid. These parameters have been investigated by various researchers and a positive enhancing trend is observed. However, stability of nanofluids has been a wide concern as various researchers struggled to maintain the stability of nanoparticle suspension.
EFFICACY OF SOME PRE AND POST-EMERGENCE HERBICIDES ON YIELD AND YIELD COMPONENTS OF CANOLA

An experiment was conducted at Malakandher Research Farm, NWFP Agricultural University, Peshawar during 2000-2001 using RCB design, having four replications. Dunkled Variety of canola in a plot size of 6x3m² was planted during the last week of October, 2000. The data were recorded on weed density m -2 , days to 50% flowering, 1000 seed weight (g) and seed yield (kg ha -1 ). None of the herbicides except Sencor WP70 had a phytotoxic effect on the crop. All the parameters were significantly affected by different herbicidal treatments. Minimum weeds 3.20 m -2 were observed in plots to which Treflan 4EC was applied as compared to 18.83 weeds m -2 counted in the weedy check plots. Thousand seed weight (3.68 g) and seed yield (1568 kg ha -1 ) were also maximum in the plots to which Treflan 4EC was applied as pre-emergence herbicide.
The study of the causal relationship between Foreign Direct Investment, Financial market development and Economic growth for eight (8) West African countries: Evidence panel data analysis

This paper examines, the dynamic interrelationships among FDI, financial development, and real output in West African Regional Financial Market covering eight (8) countries namely Benin, Burkina-Faso, Cote d'Ivoire, Bissau Guinea, Mali, Niger, Senegal and Togo. The study utilizes recent advances in panel cointegration, panel error correction models and panel granger causality test for a set of eight (8) countries using annual data running the period 1987-2010. The study identified that there is strong cointegration between the variables indicating long-run relationship. The outcome from the empirical studies demonstrate that the panel data coefficients estimated were consistent at conventional level, this confirms the overall significance of our model. We also explore the directions of causality among FDI, financial development, and economic growth and obtain solid, convincing evidence that the financial development indicators have a larger effect on economic growth than does FDI. The panel Impulse Response Functions and panel Forecast Error Variance Decomposition investigation confirm the same results mentioned above. The study concluded that financial development and foreign direct investment can be combined to influence significantly economic growth. Therefore to achieve this goal, effort should be devoted to boost saving volume while the macroeconomic environment should be made to attract more foreign direct investment into the regional market.
Evaluation of Integrated Time-Temperature Effect in Pyrolysis Process of Historically Contaminated Soils with Cadmium (Cd) and Lead (Pb)

It is already known that heavy metals pollution causes important concern to human and ecosystem health. Heavy metals in soils at the European level represents 37.3% between main contaminates affecting soils (EEA, 2007). This paper illustrates results obtained in the framework of laboratory experiments concerning the evaluation of integrated time-temperature effect in pyrolysis process applied to contaminated soil by two different ways: it is about heavy metals historically contaminated soil from one of the most polluted areas within Romania, and artificially contaminated with PCB-containing transformer oil. In particular, the authors focused on a recent evaluation of pyrolysis efficiency on removing lead (Pb) and cadmium (Cd) from the contaminated soil. The experimental study evaluated two important parameters related to the studied remediation methodology: thermal process temperature and the retention time in reactor of the contaminated soils. The remediation treatments were performed in a rotary kiln reactor, taking into account three process temperatures (400°C, 600°C and 800°C) and two retention times: 30 min. and 60 min. Completed analyses have focused on pyrolysis solids and gas products. Consequently, both ash and gas obtained after pyrolysis process were subjected to chemical analyses.
Brand identity and online self-customisation usefulness perception

ABSTRACT Online self-customisation (OSC) enables customers to tailor their preferences to certain product features via a brand-hosted online platform. The recent literature has given increasing attention to how consumers value OSC. However, extant research is characterised by a scarcity of understanding the effects of brand identity and individual differences on consumer responses to OSC. The purpose of this paper is to examine the mediating role of trust and the moderating role of need for uniqueness on the effects of brand identity prestige and brand identity similarity on consumer perceived usefulness of OSC. A field survey, through mall intercept, was conducted to test this conceptual framework. Our findings advance this field by finding that, not only the brand identity and consumer need for uniqueness but also the interaction between them may affect consumers’ evaluation of OSC.
RAILWAY CORPORATE GOVERNANCE IN A FREE-FUNCTIONING FREIGHT TRANSPORT MARKET: A SOUTH AFRICAN POSITION

Defining the economic role of rail freight transport in the national transport system of South Africa should be one of the basic ingredients of both an economically rational transport policy and the effective functioning of Transnet Freight Rail. In the interest of the national economy and in its own commercial interest, Transnet Freight Rail must only specialise in those fields where it can provide services tailored to the needs of customers at prices which are competitive and defensible in terms of economic principles. The institutional framework governing Transnet Freight Rail’s operations should create an environment conducive to the management of its operations as a fully competitive and profit-oriented business by:  fostering a competitive freight transport market;  providing any required socio-economic rail services under special agreements;  Transnet’s board of directors defining management objectives and granting real management autonomy to Transnet Freight Rail; and  Transnet Freight Rail defining clear and adequate performance indicators for itself. On the basis of these conditions, this paper outlines a governance structure under which Transnet Freight Rail as a public corporation can operate within a climate of free and effective competition.
Creating Democratic Citizens: Political Effects of the Internet in China

This study explores the perplexing role of the Internet in authoritarian settings. We disentangle the political impact of the Internet along two distinct dimensions, indirect effects and direct effects. While the direct effects of the exposure to the Internet shape political attitudes in a manifest and immediate way, the indirect effects shape various political outcomes via instilling fundamental democratic orientations among citizens. In authoritarian societies such as China, we argue the indirect effects of the Internet as a value changer tend to be potent, transformative, and persistent. But the direct effects of the Internet as a mere alternative messenger are likely to be markedly contingent. Relying on the newly developed method of causal mediation analysis and applying the method to data from a recent survey conducted in Beijing, we find strong empirical evidence to support our argument about the two-dimensional impacts of the Internet in authoritarian countries.
Foreign Presence Spillovers and Firms' Export Response: Evidence from the Indonesian Manufacturing *

This paper examines the existence of spillovers associated with the presence of multinational enterprises (MNEs) on a firm’s decision to export, and on export intensity. It utilizes data from Indonesian manufacturing for the census years 1996 and 2006. Channels through which MNEs can affect other firms’ export behavior are considered and tested. The econometric analysis suggests that the contribution of MNEs in improving technological knowledge raises the likelihood that domestic firms will enter the export market, and improves export performance. The analysis finds weak evidence to support the hypothesis that competition, created by the operation of MNEs, facilitates entry into export markets. Further analysis however shows that the impact of competition depends on the level of productivity of the domestic firms. In particular, the more productive firms are suggested to have been able to benefit more than the less productive ones. The overall analysis suggests that given the mixed evidence, policies to promote MNEs are still worth pursuing. The most obvious justification comes from the positive impact of the increased pool of technological knowledge. Other than this, strengthening trade facilitation seems to be a positive proposition, given the finding that many of the new domestic exporters seem to have been constrained in increasing their exports.
