The problem to ensure the safety of objects which are in area blasting operations, ensuring destruction hard rocks, remains relevant. article presents results a large-scale experiment determine safe conditions for conducting drilling and operations near active gas pipeline. simplest most reliable way protected object from seismic impact is reduce intensity wave, achieved by changing parameters ...

An important problem at an integrated steel producing plant is the blending of different types of coals to make coke for the blast furnace operation. Historically linear blending models were not appropriate because coal properties important for both optimum cokemaking and blast furnace operation do not combine linearly and are not completely understood. In this talk, a two-step methodology is d...

This paper mainly emphasizes development of a multifluid blast furnace model and its application to simulate several innovative ironmaking operations. At first, the development process and framework of the model are briefly introduced. Then, model simulations on hydrogen bearer injection show that the enhancement of hydrogen reduction brings the improvement of furnace performance, especially fo...

Studies of traumatic brain injury from all causes have found evidence of chronic hypopituitarism, defined by deficient production of one or more pituitary hormones at least 1 year after injury, in 25-50% of cases. Most studies found the occurrence of posttraumatic hypopituitarism (PTHP) to be unrelated to injury severity. Growth hormone deficiency (GHD) and hypogonadism were reported most frequ...

The topicality of this research is defined by the increasing volume mining operations near settlements and production infrastructure, as well unit capacity haulage equipment and, consequently, growing rock mass simultaneously blasted prepared for excavation. Changes in conditions at UK Kuzbassrazrezugol JSC have been analyzed. A brief analysis results on various factors affecting degree man-mad...

Blast-induced traumatic brain injury (TBI) has become a major issue as a consequence of deployment of military personnel under the Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) in Iraq and Afghanistan, respectively. Threats during missions of the (Dutch) troops in these recent operations are not comparable with threats experienced formerly. They now have to deal with Improv...

SUMMARY Tracker is a web-based email alert system for monitoring protein database searches using HMMER and Blast-P, nucleotide searches using Blast-N and literature searches of the PubMed database. Users submit searches via a web-based interface. Searches are saved and run against updated databases to alert users about new information. If there are new results from the saved searches, users wil...

The conventional V-BLAST detection is a single flow algorithm that consists of the two major operations: 1) the finding of the ordering index and 2) the nulling and symbol cancellation process. This paper focuses on the second operation and provides an alternative way for the nulling and symbol cancellation process using the QR decomposition to modify the V-BLAST algorithm for another way of ef...

The paper presents two sensor fusion algorithms that were utilized in a wireless sensor network-based acoustic countersniper system. The technique for fusing muzzle blast Time Of Arrival (TOA) data is able to eliminate multipath effects prevalent in urban environments and to resolve multiple simultaneous acoustic sources. The approach for fusing shockwave TOA data that are generated by superson...

A diaphragmatic injury is usually associated with injury to thoracic or abdominal organs due to blunt or penetrating trauma, and is uncommon after blast injury. We describe a patient with respiratory distress due to herniation of the stomach into the chest through a diaphragmatic injury, sustained 1 year previously when he suffered a blast injury while on deployed military operations, but witho...
