Concerns have been raised in Europe about the efficiency, sustainability, and environmental impact of the first genetically modified crops. The committees and regulators in charge of approving procedures have encouraged a field trial approach for safety assessment studies under current agronomic conditions. We describe the gene flow from sugar beet (Beta vulgaris L.) in a multi-year and multi-c...

This paper reports on an industrial application of modern signal processing technology in the development of a new automatic conveyor and bolting machine for underground coal mining. The machine is of special interest to the mining industry as it improves mine personnel safety as well as increasing the efficiency of roadway construction. We show how real-time signal processing component technol...

Ethernet has dominated due to the ease-of-use and open standard approach providing true interoperability between equipment in the field. By itself, Ethernet is not strictly a protocol yet it provides the lower ‘hardware’ layers for the higher layer software stacks such as TCP/IP or UDP. So, it would seem the task to network a device should be as simple as ‘bolting on’ an Ethernet transceiver an...

Underground coal mining is one of the most dangerous occupations. Years of effort have been dedicated to researching methods of characterizing mine roof and floor for improving the mining environment. This research investigates using a neural network to classify rock strata based on the physical parameters of a roof bolting drill. This paper presents our methodology, as well as early results ba...

Support failures in mine drifts represent potential hazards that threaten underground safety and productivity. The aim of this study is to determine the reliability index associated with rock supporting elements used Ridder-Sokolny mine, an located East Kazakhstan. Numerical simulations drift support First Order Reliability Method (FORM) were employed carry out analysis. Several cases considere...

Many abiotic factors impact the yield and growth of Brassica carinata (commonly referred to as or Ethiopian mustard). Very little is known about how mineral nutrients its growth, more specifically, sufficiency values for fertility over plant’s cycle life stages. This study explored impacts that plant nutrients, specifically micronutrients, can have on development distinct stages (rosette, bolti...
