We report the use of a porous polytetrafluoroethylene capillary for the inline separation of liquid-liquid segmented flows, based on the selective wetting and permeation of the porous capillary walls by one of the liquids. Insertion of a narrow flow restriction at the capillary outlet allows the back pressure to be tuned for multiple liquid-liquid combinations and flow conditions. In this way, ...

Chemists and chemical engineers are involved in and responsible for the life of a product from the discovery stage to manufacturing, market introduction, and end of life. They participate in and contribute to all segments of the supply chain, from cradle to grave. In the industrial sector, they work hand in hand with other professionals in engineering, business, intellectual property, and envir...

Lateral current injection (LCI) lasers are promising candidates for optoelectronic integration and novel functional devices. We investigate experimentally the performance of a new class of LCI lasers with improved operating characteristics, focusing in particular on regions of agreement and disagreement with our physical model. We then employ fully selfconsistent two-dimensional modeling in ord...

Life Cycle Assessment (LCA) is a widely accepted method for analysing the environmental aspects of goods and services. Life Cycle Inventory (LCI) datasets document the various involved material and energy flows, forming the basis of every LCA study. Today, a plurality of databases providing LCI data exists. Data delivered by these databases has to be sound as well as suitable for the specific a...

This document specifies a Dynamic Host Configuration Protocol Option for the coordinate-based geographic location of the client. The Location Configuration Information (LCI) includes latitude, longitude, and altitude, with resolution indicators for each. The reference datum for these values is also included. Polk, et al. Standards Track [Page 1] RFC 3825 DHCP Option for Coordinate LCI July 2004...

Rapid socio-economic and technological changes have urged the implementation of new approaches to procure construction projects. Total Quality Management (TQM) is one of the approaches that contribute towards ensuring that projects are being delivered to the stakeholder requirements. This study identifies critical success factors (CSFs) that affect the implementation of TQM in the Libyan Constr...

Life Cycle Assessment (LCA) is a systematic evaluation of the potential environmental impact and resource utilization of a product from raw material through disposal. Underlying the LCA is the Life Cycle Inventory or LCI, a quantification of energy and material inputs and environmental release or emissions data associated with product creation and use. The primary purpose of this project was to...

We investigate several complexity issues related to branch-and-cut algorithms for 0-1 integer programming based on lifted cover inequalities (LCIs). We show that given a fractional point, determining a violated LCI over all minimal covers is NP-hard. The main result is that there exists a class of 0-1 knapsack instances for which any branch-and-cut algorithm based on LCIs has to evaluate an exp...

Starting from the basic pillars of the supportability analysis this paper queries its characteristics in LCI (Life Cycle Integration) environment. The research methodology contents a review of modern logistics engineering literature with the objective to collect and synthesize the knowledge relating to standards of supportability design in e-logistics environment. The results show that LCI fram...
