Extension of EOQ model with emergency orders and explicit energy cost considerations
Given the rising cost of energy, this research studies the effect of energy cost on logistics decisions by analyzing the effect on inventory ordering policies for production systems with constant production rates but small, underlying possibilities for undesirable circumstances to threaten the …

Project process mapping : evaluation, selection, implementation, and assessment of energy cost reduction opportunities in Manufacturing
… 2011, in part due to increasing reliance on high-cost fossil fuels. A focus on reducing these costs has identified numerous energy-saving projects in recent years, but with mixed implementation and performance results between the different plants in the region. Consequently, there is both a need …

Creating a green baloney detection kit for green claims made in the CNW report : Dust to Dust : the energy cost of new vehicles : from concept to disposal
In order to assess the veracity of a green claim made by CNW marketing research Inc., I created a green baloney detection kit. It will serve as a guiding post by which anyone can assess the potential environmental impact of any action taken on the basis of the claims made by CNW in their dust to …

CHARACTERIZATION AND FUNCTIONALITY OF RECOMBINANT AQUAPORINS FROM MOZAMBIQUE TILAPIA
With the high energy cost of reverse osmosis acting as the main pipeline for desalination in Singapore, the low energy cost biomimetic membrane incorporated with aquaporin, having high water selectivity and permeability, are of interest. Hereby, we propose that Mozambique tilapia (Oreochromis …

Climate Change and Aging: analyzing the disproportionate health and socioeconomic vulnerabilities of older adults in relation to the climate crisis in the U.S.
… the outdoor temperatures at home through home energy use. However, older adults living at or below the poverty level may not be able to manage the associated costs of home energy usage. This research builds upon previous work on climate justice by assessing the additive components of poverty, …

Modeling thermal environment of a recirculating aquaculture system facility
… system (RAS) facility depends on minimizing the energy requirements of operating such facilities. The fish growth and water quality aspects of RAS have been studied in considerable details. However, the understanding of the thermal environment of RAS lags behind. A step-wise steady-state thermal …

A methodology for the evaluation of thermal performance of windows based upon life-cycle cost
… from the natural environment. The life-cycle cost model allows evaluations which will influence the glazing selection in response to seasonal changes in insolation and the net energy effect of orientation. The research consisted of two phases. The first included a search of the literature on …

Leveraging Capillarity
… Superhydrophobicsurfaceshave a high surface energy cost with water, resulting in small contact areas with high advancing and receding contact angles and low contact angle hysteresis. This results in very low adhesion on the surfaces. Here we study the ability of superhydrophobic surfaces with …
