introduction this study was carried out in order to compare mineral trioxide aggregate (mta) and dycal in dog’s teeth as pulp capping agents. methods after general and local anesthesia forty-two teeth of three dogs were used. in each tooth a class v cavity was prepared and the pulp was exposed using no.1 round bur. then the exposed area was capped using either mta or calcium hydroxide and the r...

Elevation of the penis and scrotum after scrotal and pelvic surgery has the salutory effects of facilitating the resolution of postoperative swelling while simultaneously preventing the development of dependent edema. Previously, the desired degree of postoperative genital suspension has been achieved by employing an athletic supporter and by placing towel rolls beneath the scrotum. These measu...

Oscillators are kernel components of electrical and electronic circuits. Discussion of history, mechanisms and design based on Barkhausens observation. Discussion of a Wien Bridge oscillator based on the question: Why does this circuit oscillate ?

Redband trout (Oncorhynchus mykiss ssp.) in southeastern Oregon inhabit high-elevation streams that exhibit extreme variability in seasonal flow and diel water temperature. Given the strong influence and potential limitations exerted by temperature on fish physiology, we were interested in how acute temperature change and thermal history influenced the physiological capabilities and biochemical...

Estimating maximum scour depth is normally required in order to determine the depth of  bridge piles. The present paper uses the SSIIM Software which considers flow and sediment equations in a three dimensional manner. The software models flow field around circular bridge pile by resolving Navier-Stokes three-dimensional equations and k-  method, and by temporary solution of flow field and cont...

In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...

In this study, a system for monitoring the structural health of bridge deck and predicting various possible damages to this section was designed based on measuring the temperature and humidity with the use of wireless sensor networks, and then it was implemented and investigated. A scaled model of a conventional medium sized bridge (length of 50 meters, height of 10 meters, and with 2 piers) wa...

4 (1) studied the bridge choice behavior of commuters before and after a new bridge opened to the 5 public. This bridge replaced the previously collapsed I-35W bridge in the metro area of Minneapolis-St. 6 Paul. The original I-35W bridge collapsed on August 1st 2007, and the replacement bridge opened to the 7 public on September 18th 2008. This study extends (1) by considering explicitly the da...

This paper describes a method of performance evaluation and remaining life prediction for an aged reinforced concrete (RC) T-girder bridge by J-BMS RC version via close visual inspection data, and also verifies the assessment results obtained as outputs from the Bridge Rating Expert System (RC-BREX) which is a subsystem of the J-BMS, to evaluate the effectiveness of the system. The Bridge Manag...

a new fixed-partial denture design using laminates is described for the replacement of a missing anterior tooth. in this article advantages, disadvantages, indications and contraindications of the new design have been discussed. this method is best suited for cases with missing incisors and esthetically compromised abutment teeth.
