An extensive program of laboratory model tests was undertaken to study the effect of slope and loading direction on laterally loaded piles in cohesionless soil. The paper includes studies of the effect of distance from the crest of the slope (both slope side and embankment side), soil properties, and loading direction (both forward in the direction of the slope and reverse loading). The pile lateral capacity in sloping ground was compared with that in horizontal ground. From the experimental investigation, it is observed that when piles installed in sloping ground undergo forward loading, lateral capacities of the piles are almost reached at 8% of the pile diameter in loose-to-medium dense soil and 16% of the pile diameter in dense soil. If the pile is placed >15 times the pile diameter away from the slope crest within the embankment, the influence of slope in the lateral-load capacity is almost negligible under both forward and reverse lateral load. © 2014 American Society of Civil Engineers.

Purpose: The auto ancillary industry in India has witnessed huge capacity expansion and modernization due to entry of foreign automobile manufacturers in the post liberalization era. In spite of potential benefits, the adoption of advanced IT among small to medium-sized enterprises (SMEs) is low in India. There are several technological, economical and organizational factors that enable or inhibit the adoption of advanced IT. The primary objective of this research is to identify and evaluate the key factors that are enabling or inhibiting adoption of advanced IT in the Indian auto ancillary SMEs. Design/methodology/approach: In order to identify and evaluate the enablers and inhibitors, a detailed survey was carried out among registered Indian auto ancillary SMEs during 2010. Out of 584 registered SMEs, 110 owners/top managers of the SMEs responded to the survey. The data collected through the survey were analyzed using confirmatory factor analysis and multivariate regression to evaluate the influence of enablers and inhibitors of advanced IT adoption by the auto ancillary SMEs. Findings: The survey findings show that the level of advanced IT adoption in auto ancillaries is low with only 17 per cent of SMEs having adopted technologies. This study reveals that "perceived benefits" and "perceived competitive pressure" enable advanced IT adoption among auto ancillary SMEs in India. However, "lack of financial capacity", "small scale operation and "lack of in-house IT manpower" inhibit the adoption. It is also found that enablers such as "changes in business environment", "IT experience of CEO/owner" and "increased information linkage with OEM/customer" do not have any influence on the adoption. Similarly in the case of inhibitors, "lack of IT Infrastructure" and "lack of information security" do not have significant association with IT adoption. Despite the positive external IT environment and recognition of benefits, advanced IT adoption by SMEs in the auto ancillaries is limited by lack of financial capabilities and in-house IT human resources. Originality/value: This is one of the early papers that brings out the enablers and inhibitors of advanced IT adoption by auto ancillaries in India. Further, these factors are systematically analyzed to assess the relative importance with reference to the SMEs. The findings contribute to theory of IT adoption among SMEs, but more importantly to the SMEs in the auto ancillary, and policy makers and IT service providers who are likely to facilitate increased adoption. © Emerald Group Publishing Limited.

Increasing competition has been forcing the modern manufacturing organisations to adopt advanced manufacturing paradigms. Agile Manufacturing (AM) is an advanced manufacturing paradigm that enables an organisation to survive in the competitive business environment. Agility is the performance measure of AM practices. Simultaneously, modern business organisations are forced to evolve environmental friendly products. Sustainability is regarded as an important concept for survival by the modern organisations. In this context, agility and sustainability are regarded as performance measures for contemporary organisations. This paper reports a case study which has been carried out in an Indian rotary switches manufacturing organisation. The candidate product is the knob of rotary switch. Initially Computer Aided Design (CAD) has been used to digitalise the baseline model. Keeping the baseline model as reference, five new knob models have been evolved. Then the sustainability analysis has been carried out to determine the environmental impact of the knob models. The analysis results indicated that the proposed knob models possess minimal environmental impact. The conduct of case study has lead to an inference that there is a significant improvement of agility and sustainability in the design and development of knob of rotary switch. © 2010 Elsevier Ltd.

Experiments were conducted on a single cylinder direct injection diesel engine using diesel, biodiesel and biodiesel-diesel-ethanol (diestrol) water micro emulsion fuels to investigate the performance, emission and combustion characteristics of the engine under different load conditions at a constant speed of 1500 rpm. The results indicated that biodiesel and micro emulsion fuels had a higher brake specific fuel consumption (BSFC) than that of diesel. A slight improvement in the brake specific energy consumption (BSEC) was observed for micro emulsion fuels. The brake thermal efficiency of biodiesel and micro emulsion fuels were comparable to that of diesel. The emission characteristics like carbon monoxide (CO), carbon dioxide (CO2), unburnt hydrocarbon (UHC), nitric oxide (NO) and smoke emissions for biodiesel and micro emulsion fuels were lower than diesel fuel at all load conditions. The cylinder gas pressure of micro emulsion fuels was lower than diesel at low loads but it became almost identical to diesel at medium and full load conditions. The heat release rate for micro emulsion fuels was higher than biodiesel and diesel fuels for all loads. Biodiesel showed shorter ignition delay for the entire load range and the longer ignition delay observed for micro emulsion fuels. © 2011 Elsevier Ltd.

Organic compound, especially aromatic compound is the main pollutant in industrial effluent. Conventional wastewater treatment processes are inefficient for the removal of these types of toxic and hazardous pollutants from wastewater. Electro Fenton is one of the powerful and environmentally friendly emerging technologies for the remediation of wastewaters containing organic, especially aromatic compounds. This paper reviews the fundamentals and recent developments in electro Fenton process. Electro Fenton process utilizes different electrolytic reactors such as bubble reactor, filter press reactor, divided double-electrode electrochemical cell, divided three-electrode electrochemical cell and double compartment cell. Different cathodes as working electrode and anodes as counter electrode used in this process are analyzed. The effects of various operating parameters and their optimum ranges for maximum pollutant removal and mineralization are reviewed. Also various pollutants removed by this process are evaluated. Quick removal and mineralization of pollutants and their intermediate reaction products were reported. © 2012.
