This study aims at providing a relatively straightforward methodology to serve as a decision-making tool when more than one packaging solution could be available to a user. It involves a life cycle inventory (LCI) analysis and comparison of three currently available 3.79 l (1 gallon) packaging systems for liquid milk. Two of the primary container types studied use reusable plastic crates (RPCs)...

introduction: active packaging is one of the innovations in food packaging industry that would be a respons to the changing needs of consumers and markets. in this technique, materials such as adsorbents oxygen, moisture, carbon dioxide, ethylene and carbon dioxide-releasing flavor compounds, antimicrobials, antioxidants and various aromatic compounds are used. in the last decade, great attenti...

We are currently investigating parallel optoelectronic computing systems based on three dimensional hierarchical architectures[1]. We have previously constructed a system in which two dimensional processing element (PE) arrays are connected by dynamically recon gurable optical interconnections [2]. Current developments in such demonstrator circuits concentrate on improved performance as well as...

introduction: ambulatory care is an inseparable part of health care system. it is commonly considered as the entrance of the patient to the health care system. high qualify ambulatory care has an important role in reducing mortality and morbidity rates. on the other hand, quality of information has an important role in the quality and safety of ambulatory health care. it is hence necessary to p...

Interest in the use of active and intelligent packaging systems for meat and meat products has increased in recent years. Active packaging refers to the incorporation of additives into packaging systems with the aim of maintaining or extending meat product quality and shelf-life. Active packaging systems discussed include oxygen scavengers, carbon dioxide scavengers and emitters, moisture contr...
