It is well-known that entrainment of particles into the froth is a key factor in the selectivity and performance of the flotation process, especially for fine particle recovery. Since flotation is a continuous process, in this work, the effects of operating parameters on the entrainment of ash materials in a sample coal flotation is investigated from a time-sequence viewpoint. The effects of th...

introduction: effects of exercise on different body systems, especially cardiovascular and musculoskeletal systems are evidenced. there is a dynamic homeostatic balance between coagulation and fibrinolysis in normal circulation. effect of exercise and training on this homeostatic balance has been studied extensively but there are a few studies with regards to analysis of the effects of training...

Spinal cord injury (SCI) is a trauma that disturbs motor, sensitive and autonomic function and directly impacts the quality of life. After physical damage, releasing of pro-inflammatory proteins and cytokines occurs and with collaboration of immune system cells, an immune response begins in the brain tissue. The result of neuroinflammation is edema, apoptosis and release of axonal growth inhibi...

The root is an important plant part contributing to peanut productivity underwater-limited conditions. Root volume, root surface area and root diameter may becharacters responding to pre-flowering drought (PFD) in peanut. The objectives ofthis study were to investigate the responses to PFD for root surface area, rootvolume and root diameter and to determine the inter-relationships among theresp...

During disaster response and recovery operations, civil engineers can be assigned a multitude of tasks including triage of building search priorities, identifi cation and evaluation of structural hazards, as well as the development of appropriate structural hazard mitigation techniques and monitoring of hazards, while coordinating and reporting this information to the incident command centre (I...

The severity and number of intrusions on computer networks are rapidly increasing. Preserving the availability and integrity of networked computing systems in the face of those fast-spreading intrusions requires advances not only in detection algorithms, but also in intrusion tolerance and automated response techniques. Additionally, the rapid size and complexity growth of computer networks, an...

On September 21, 1999 the 921 or Chi Chi earthquake struck the centre of Taiwan. The earthquake’s magnitude was ML 7.3, and MW 7.7 and the epicentre depth was 8 km. The earthquake hit at 1:47 am, and left about 2,471 dead and 11,305 seriously injured. Over 10,000 buildings collapsed and direct losses were estimated at US$14 billion. This paper describes some of our preliminary findings on a Nat...
