ROLLING RESISTANCE OF ATV TYRES IN AGRICULTURE

Antimicrobial Resistance in Agriculture.

In this article, the current knowledge and knowledge gaps in the emergence and spread of antimicrobial resistance (AMR) in livestock and plants and importance in terms of animal and human health are discussed. Some recommendations are provided for generation of the data required in order to develop risk assessments for AMR within agriculture and for risks through the food chain to animals and h...

Systemic Acquired Resistance and Induced Systemic Resistance in Conventional Agriculture

Heynh., demonstraPlants possess a range of defenses that can be actively expressed ting that SAR was conserved across diverse plant famiin response to pathogens and parasites of various scales, ranging from microscopic viruses to insect herbivores. The timing of these defense lies and was effective agains...

Antimicrobial Resistance Issues In Animal Agriculture

Optimum Thread Rolling Process proves SGC Resistance

Accelerated testing in environments aggressive for the specific material have shown that fastener threads that are rolled after strengthening heat treatments have improved resistance to SCC initiation. For example, intergranular SCC was produced in one day when machined (cut) threads of high strength steel (ASTM A193 B-7 and A354 Grade 8) were exposed to an aggressive aqueous environment contai...

Wheelchair tire rolling resistance and fatigue.

The hysteresis loss theory of rolling resistance is developed for solid rubber wheelchair tires. The analysis is used to correlate test data for a clay-filled natural rubber and a polyurethane tire material. A discussion of tire rolling work, hysteresis loss factor measurement, and rolling loss measurement is presented. An example calculation of rolling resistance for a polyurethane tire is giv...
