Advanced Planning in Fresh Food Industries: Integrating Shelf Life into Production Planning
Production planning in fresh food industries is a challenging task. Although modern Advanced Planning and Scheduling (APS) systems could provide significant support, APS implementation numbers in these industries remain low. Therefore, based on an in-depth analysis of three sample fresh food industries (dairy, fresh and processed meat), the author evaluates what APS systems should offer in order to effectively support production planning and how the leading systems currently handle the most distinguishing characteristic of fresh food industries, the short product shelf life. Starting from the identified weaknesses, customized software solutions for each of the sample industries are proposed that allow to optimize the production of fresh foods with respect to shelf life.
Academic Study of Common Diets
The foods you choose to eat can have a direct impact on your ability to enjoy life to its fullest. Perhaps the most obvious positive effect of food is the pleasurable feeling you get from eating a good-tasting meal. Over the past decade there has been an increasing concern about the impact of chronic diseases on the health of developing world populations. Traditionally, major causes of illness and death in developing countries have been linked to infectious diseases and undernutrition, and these are still major public health problems in several regions of the world. Obesity is recognized as an underlying risk factor for many of these chronic conditions. As in developed societies, the risk of obesity in developing countries is also strongly influenced by diet and lifestyle, which are changing dramatically as a result of the economic and nutrition transition.
Abiotic Stress Tolerance in Plants : Toward the Improvement of Global Environment and Food
Stresses in plants caused by salt, drought, temperature, oxygen, and toxic compounds are the principal reason for reduction in crop yield. For example, high salinity in soils accounts for large decline in the yield of a wide variety of crops world over; ~1000 million ha of land is affected by soil salinity. Increased sunlight leads to the generation of reactive oxygen species, which damage the plant cells. The threat of global environment change makes it increasingly demanding to generate crop plants that could withstand such harsh conditions. Much progress has been made in the identification and characterization of the mechanisms that allow plants to tolerate abiotic stresses.
A Sea Change: The Exclusive Economic Zone and Governance Institutions for Living Marine Resources
A Sea Change in a Changing Sea The oceans, seas and coastal areas encompass over 70% of the earth’s surface. They are a critical driver of the earth’s hydrologic cycle and climate system, important for c- merce, transport, and tourism, a source of economically important living marine resources, minerals such as hydrocarbons, as well as new pharmaceutical compounds. The marine environment provides essential habitats for thousands of marine living 1 2 resources, which in turn contribute significantly to global food security, employment, 3 and trade. Overall, the sea’s contribution to human welfare, in terms of market and non-market resources and environmental services, has been estimated at US$21 trillion/year (Costanza, 2000). However, despite the importance of the ocean realm to humans, there is a growing sense that human impacts are destabilizing this system. Some experts believe that current fishing levels are approaching or exceeding the total 4 productivity of the ocean ecosystem (National Research Council, 1999).
A Portrait of State-of-the-Art Research at the Technical University of Lisbon
This book contains the edited version of the invited lectures that were delivered by prominent researchers at UTL. This book brings together in a review manner a comprehensive summary of high quality research contri- tions across basic and applied sciences. The contributing papers are organized around the following major areas: – Emergent areas (Nanosciences, Quantic Computations and Infor- tion, Risk and Volatility in Financial Markets); – Basic Sciences (Mathematics, Physics, Chemistry and Materials); – Social Sciences, Economics and Management Sciences; – Life Sciences and Biotechnology; – Engineering and Technologies – Nature, Environment and Sustainability; – Public Health, Food Quality and Safety; – Health and Sport Sciences; – Urbanism, Transports, Architecture, Arts and Design.
A History of Thermodynamics : The Doctrine of Energy and Entropy
The development of thermodynamics in the second half of the 19th century has had a strong impact on both technology and natural philosophy. It is true that the steam engine for the conversion of heat into work existed before thermodynamics was developed as a branch of physics. However, the systematic theory improved the conversion process, and it succeeded in developing other processes essential to modern life, notably refrigeration and rectification. So, altogether thermodynamics has provided humanity with cheap energy, and cheap fuel, -- consequently with cheap, and abundant, and unspoiled food. Thus thermodynamics has made populations grow, and life expectancy increase beyond anything people could possibly have imagined 200 years ago.
