A Hybrid Kinematic-Acoustic System for Automated Activity Detection of Construction Equipment.

Automatically recognizing and tracking construction equipment activities is the first step towards performance monitoring of a job site. Recognizing equipment activities helps construction managers to detect the equipment downtime/idle time in a real-time framework, estimate the productivity rate of each equipment based on its progress, and efficiently evaluate the cycle time of each activity. Thus, it leads to project cost reduction and time schedule improvement.

Field Evaluation of N95 Filtering Facepiece Respirators on Construction Jobsites for Protection against Airborne Ultrafine Particles.

Exposure to high concentrations of airborne ultrafine particles in construction jobsites may play an important role in the adverse health effects among construction workers, therefore adequate respiratory protection is required. The performance of particulate respirators has never been evaluated in field conditions against ultrafine particles on construction jobsites. In this study, respiratory protection levels against ultrafine particles of different size ranges were assessed during three common construction related jobs using a manikin-based set-up at 85 L/min air flow rate.

Evaluation of the disintegration of linen fabric under composting conditions.

In recent years, about 10% of the total wastes generated around the world were fabric wastes and, due to the large volume of these wastes, should be well managed. Among the various types of fabrics, some have greater biodegradability and can be decomposed at the acceptable rates under controlled conditions. In this study, the disintegration of linen fabric was investigated under composting conditions.

Long term effects of below-the-knee angioplasty in diabetic patients with critical ischemia of lower limbs referred to Sina Hospital during 2010-2011.

Unlabelled: Despite significant advances in the treatment of diabetic foot ulcers and below-the-knee critical ischemia, there are ongoing efforts to achieve a method with low complication, high success rate and persistence of long-term effects. The aim of the study was to examine the outcome of angioplasty in patients with below-the-knee critical ischemia referred to Hospital.

Material And Methods: This semi-experimental study conducted on diabetics patients treated with PTA (Percutaneous transluminal angioplasty) with critical ischemia of lower limbs referred to Sina Hospital.
