Quantifying energy savings from replacement of old refrigerators

Energy Procedia, 2017
Abstract: Energy labelling for refrigerators in Australia has been in force for over 30 years. It is well documented that the label energy consumption of refrigerators and freezers has fallen dramatically over that period. While a number of studies have measured the energy consumption of refrigerating appliances in the field, the data is very complex

The Faraday Scalpel: Electrochemical Nerve Lesioning Mechanisms Studied in Invertebrate Models

Advanced Science, EarlyView.
Direct‐current produces nerve lesioning through discrete electrochemical reactions. Using hypoxia‐sensitive locust nerves and hypoxia‐tolerant leech nerves, we map three injury pathways: cathodic oxygen reduction, cathodic alkalization, and anodic chloride oxidation. These findings establish electrochemical lesioning—the “Faraday Scalpel”—as a precise,

Defining the Legal and Policy Framework to Stop the Dumping of Environmentally Harmful Products [PDF]

, 2018
Environmental dumping is a practice historically associated with the export of hazardous product waste from a developed country for irresponsible and often illegal disposal in a developing country.

Lyophilized Synthetic Platelets: In Vitro Characterization and in Vivo Evaluation in Mouse Thrombocytopenia Model

Advanced Science, EarlyView.
ABSTRACT Platelet transfusions to treat bleeding complications use donor‐derived platelets stored at room‐temperature, that have a shelf‐life of only 5–7 days due to bacterial contamination risks. Cold‐stored and freeze‐dried platelets are being investigated for extending shelf‐life, but these still have the inherent challenge of donor‐dependency.

HVAC SYSTEM REMOTE MONITORING AND DIAGNOSIS [PDF]

, 2019
A monitoring system for an HVAC system of a building includes a monitoring server located remotely from the building. The monitoring server receives, from a device installed at the building, (i) time-domain current data based on a measured aggregate ...

Retrofit of lower GWP alternative R449A into an existing R404A indirect supermarket refrigeration system [PDF]

, 2017
R404A is going to be phased out from most of the commercial refrigeration systems due to its high GWP value of 3943. R449A (GWP of 1282) has been proposed to replace R404A with only minor system modifications in supermarkets.

Soft and Adhesive Cardiac Patch for Electrophysiological and Contraction Measurement

Advanced Science, EarlyView.
This study developed an epicardial electronic patch with a modulus similar to that of the heart (approximately 65kPa), which can collect stable electrocardiogram signals and myocardial contractility on the surface of a dynamically beating heart. This is attributed to the hydrogen bond interaction formed between the amino and catechol groups in the ...

Performance of an oil-free linear compressor using R1234yf [PDF]

, 2018
As an alternative to the hydrocarbons (HCs), R1234yf synthetic refrigerant from the family of the hydrofluoroolefins (HFOs), has emerged recently as a replacement fluid for R134a. The purpose of this study is to investigate the performance of an oil-free
