I t is indeed an honor to be invited to this platform. One has only to read the names of my distinguished predecessors to realize that, as the saying goes, I have thirty-seven acts that are hard to follow. As a mostly pure mathematician my concern is increased when I note that thirty-two of the lectures have dealt with applications of mathematics to other sciences. The true desperation of my pr...

Stimuli-responsive metal-organic frameworks (MOFs) have gained increasing attention recently for their potential applications in many areas. We report the design and synthesis of a water-stable zirconium MOF (Zr-MOF) that bears photoresponsive azobenzene groups. This particular MOF can be used as a reservoir for storage of cargo in water, and the cargo-loaded MOF can be further capped to constr...

We present an extensive review of the literature on remote sensing and land change in Amazonia as part of a call for new methods to study the recent expansion of mechanized annual cropping. Following the review is a presentation of the use of multitemporal Moderate Resolution Imaging Spectroradiometer (MODIS) 250-meter Vegetation Index (VI) data to study processes of intensification of mechaniz...

nitrogen is one of the most important nutrients in crop production, but it's losses to the environment is harmful. the sundial model (simulation model of n dynamics in the soil) was used to quantify the cycle of n and it's losses in different production systems of sugar beet (beta vulgaris l.) in former khorasan province, east of iran. the data were collected from traditional, semi-me...

the nutritional value of cereal straw can be increased using urea treatments as a source of ammonia. the conventional urea treatment process for cereal straw is a laborious and time-consuming task. it is essential to facilitate or eliminate part of the procedure with the use of machinery. this study examines the mechanical urea treatment of wheat straw and compares chemical components and diges...

Debates over the effects of technological change on work continue to generate a wide and confusing array of findings. One reason for the lack of consensus is that empirical research based on large samples has yet to adequately address the core issue: the relationship, if any, between the level of mechanization and the characteristics of work. This relationship is explored using data from the 19...

One of the important factors affecting quality mechanized potato harvesting is technical condition combine. To maintain necessary level reliability and durability agricultural machinery used in process, authors proposed to diagnose mechanical drive combine with two modes scrolling shaft: free fixed. This approach allows you determine dynamic indicators by which it possible identify malfunctions...
