Description

Concrete carbonation decreases durability of concrete. Therefore, quantitative evaluating method for the amount of CO₂ absorption through carbonation should be considered under the condition that carbonation does not affect durability of RC structure. This study proposed a quantitative evaluating method that overcomes the limitation of the traditional qualitative evaluation, which is carried out using the naked eye with respect to the color change boundary by spraying indicator. Carbonation depth becomes the basic data for estimating the residual life and durability of RC structures. To achieve this objective, the quantitative change of Ca(OH) ₂ and CaCO₃ for each depth in concrete according to the carbonation process is measured using TG/DTA in order to propose a quantitative method and an evaluation basis. Another goal is to propose evaluating method of CO₂absorption in the air through carbonation and how to evaluate LCCO₂(emission – absorption of CO₂).

About this book:

The present book reports upon the results of scientific and technical research conducted for five years, between 2009 and 2013, by a group of cca 10 scientists, engineers and technicians at MiraTechnologies, Bucharest, Romania, upon some devices of remote detection with rotating antenna.

It is known that an important problem today in our society consists in combating the terrorist acts by detecting explosives or narcotics, as well as other illegal materials. Of course, a remote detection is the most desirable one. There exists, since long, on the international technological markets a series of devices which seem to be able to perform such a remote detection. All these devices (some of them reviewed in the book) share as a common element a rotating antenna which can swivel about its axis and point to the target in the field. These devices, which evoke a charming rod, a magic wand or the famous dowsing rod, have the aspect of a rather small device, like a pistol, which the operator holds in hand. 

The functioning of these devices was never convincingly proved, and their validity is controversial. 

MiraTechnology became interested in such devices and, about 2009, started to assemble a team of researchers in order to help clarify the functioning of these curious devices. The studies carried out by these researchers (their leaders are this book’s authors), both experimental and theoretical, resulted in a series of scientific publications listed below. The main conclusion of these studies is that there exist firm principles in science which make possible the functioning of such devices. The results of these studies are presented in this booklet.

Description:
Reconstruction of the Temporo-mandibular joint (TMJ) represent a challenge for all craniofacial and maxillofacial surgeons for the last 4 decades, many disease of the TMJ were not fully understood in the west (like TMJ ankylosis), since they do not see much of these cases as in the Middle east because the standard of health education to understand the basic roles for managements of traumatic injuries of the TMJ is absent.

In the south of Arab land as in Yemen, Somalia and Sudan, people daily habit of chewing Qat which is the main cause for destruction of the TMJ structures featuring, recurrent dislocation and subluxation of the TMJ.

Great advances carried out by pioneers in TMJ surgery to understand the pathogenesis of these destructive disease of the TMJ by advocating many surgical procedures and techniques for reconstruction of the TMJ by using either autogenously tissue or metals such as 2 part prosthesis or sialastic (Rubber Silicon) or temporalis muscle flap for treatment of ankylosis or by using different techniques for managements of subluxation and dislocation including seclerosing materials like STD or by reinforcement by placation of the capsule or by reconstruction of the capsule by finger like temporal fascia flap or making an obstacle by augmentation of the zygomatic root of temporal bone by bone graft from iliac crest. Using Botox A injection to the upper part of lateral petrygoid muscle to delay the action of the muscle connected to the disc, to stabilize the disc and to prevent further movement of the condyle forward behind the articular eminence to prevent clicking of the disc and to prevent unpleasant noises.

Other diseases of the TMJ that required reconstruction such as hemi facial microsomia or first arch dysplasia syndrome and hypoplasia of the condyle, these cases either the TMJ reconstructed by autogenous tissue like costo-chondral graft or by chondro-ossous graft, these two procedures were used for managements of ankylosis of the TMJ in children and for reconstruction of the TMJ in other congenital or inquired disease.

In cases of hemi facial microsomia which required a series of operations for correction of cleft of the angle of the mouth, reconstruction the atrophied masseter muscle by platysma muscle flap, removal or excision of tags in front of the ear as remnants of Meckels cartilage fallowed by reconstruction of the TMJ by Chondro-Ossous graft from iliac crest after reconstruction of the glenoid fossa by cartilage from the ear and reconstruction of zygomatic arch by bone graft from iliac crest.

Experimental studies on Iris Monkeys or Rabbit were of great value for application of these new surgical procedures on humans.

All these procedures and techniques did great progress to surgery of the TMJ and also we got the ability to understand the pathology of these diseases.

We hope to present to our colloquies worldwide the fruit of our long and valuable experience and to share with them this knowledge and experience and we hope we did contributions to science.
