INTRODUCTION Reducing costs by improving storage efficiency has been a focus of the National Heart, Lung, and Blood Institute (NHLBI) Biologic Specimen Repository (Biorepository) and Biologic Specimen and Data Repositories Information Coordinating Center (BioLINCC) programs for several years. METHODS Study specimen profiles were compiled using the BioLINCC collection catalog. Cost assessments...

During normal sample preparation, storage in freezers and subsequent freeze/thaw cycles are commonly introduced. The effect of freeze/thaw cycles on the metabolic profiling of microalgal extracts using HR-MS was investigated. Methanolic extracts of monocultures of Arctic marine diatoms were analyzed immediately after extraction, after seven days of storage at -78 °C (one freeze/thaw cycle), and...

Nowadays, high importance is given to low energy devices (such as refrigerators, deep-freezers, washing machines, pumps, etc.) that are able to produce reactive power in power lines which can be optimized (reduced). Reactive power is the main component which overloads power lines and brings excessive thermal stress to conductors. If the reactive power is optimized, it can significantly lower th...

This paper presents a simulation study carried out to solve a problem of manufacturing process reengineering. The specific company in which the study took place is a medium size manufacturer of chest freezers, which required an in-depth analysis of its manufacturing operations in an attempt to increase its throughput and overall productivity. A simulation model of the current manufacturing syst...

In California, commercial refrigeration accounts for 14% of electric energy usage, corresponding to 9,014 GWh per year and affecting more than 110,000 commercial establishments. A single walk-in freezer uses more energy than 5 single-family houses. Despite more stringent standards and utility programs promoting hardware improvements, controls systems used for commercial refrigerators are still ...

How and why do people store food? What norms, skills items are involved in practices of stocking up keeping food pantries, refrigerators, freezers? Despite an increasing interest everyday within studies, research on domestic storage is limited. In this article I depart from a practice theoretical framework to explore how made meaningful involve certain competences materials, with focus prepared...

This study discusses methods for the sustainability of freezers used in frozen storage known as long-term food methods. Freezing preserves quality a long time. However, it is inevitable to use freezer that uses large amount electricity store with this method. To maintain food, lower temperatures are required, and therefore more electrical energy must be used. In study, machine learning was perf...
