Since the beginning of agriculture plants and animals used by man were genetically modified, sometimes very fundamentally. As a consequence cultivars of cultivated plants rarely can survive outside agriculture. Genetic modifications selected by man were those which increased the agricultural productivity of plants. The constant progress in the productivity of plant production was the basis for ...

I show that both ...

Despite substantial advances in milk production efficiency of dairy cattle over the last 50 years, rising feed costs remain a significant threat to producer profitability. There also is a greater emphasis being placed on reducing the negative impacts of dairy production on the environment; thus means to lower greenhouse gas (GHG) emissions and nutrient losses to the environment associated with ...

Sustainability in production processes is mandatory in the manufacturing environment due to restrictions such as legislation. Conventional Manufacturing Execution Systems (MES) don’t really support environmental sustainable goals but are actually the most suitable background for an extension towards sustainability monitoring, control and assessment. This paper introduces a new MES generation wh...

Measuring timetable robustness is a complex task. Previous efforts have mainly been focused on simulation studies or measurements of time supplements. However, these measurements don't capture the production flexibility of a timetable, which is essential for measuring the robustness with regard to the trains' commercial activity commitments, and also for merging the goals of robustness and effi...

A form for homogeneous functions is presented which shows them to be a very simple extension of the wellknown Cobb-Douglas functions with similar properties in production (and distribution) economics. This form thus suggests new possibilities for interpreting a wide variety of empirical and theoretical results in economics; it also provides contact with developments in other fields, such as inf...

 Undoubtedly, the twentieth century can be regarded as one of the richest periods of the history of philosophy and thought which globalized this tradition, generally, because of the spread of mass media and even the published books, and joined all vast and narrow streams, here and there, together and at their Juncture a big sea is formed which is the most important gain of the century. One of t...

We analyze the possibilities for studying properties of dense QCD-matter, created in ultrarelativistic nuclear collisions, by hard QCD-production processes, so-called ”hard” probes – heavy quarkonia, hard jets, high mass dimuons. Special attention is paid to the potential of coming heavy ion experiments on Large Hadron Collider to observe the rescattering and energy losses of hard partons in qu...
