Potential use of mesenchymal stem cells and bio-oss® in surgery skull-Maxillo-facial: a review

The WHO (World report on road traffic injury prevention, 2002) predicts that by 2020 road accidents are the third leading cause of facial trauma in the world. Moreover, according to the Brazilian Association of organ transplantation, the number of bone transplants per million population reaches 450 (18,200 transplants). The lack of bone in the alveolar ridge has been a major problem in functional aesthetic recovery in patients who have suffered dentoalveolar trauma, traumatic dental extractions, dental congenital absence, disease involving the maxilla and mandibular.

The effect of Solenostemma argel leaves extract on status of induced lipid constituents in albino rats

All cultures and societies have knowledge best described as folk medicine, and Sudanese people used S. argel to treat many diseases among them Hyperlipidemia. In this study the effect of ethanolic leaves extract of S. argel on lipid profile was examined in two groups of albino rats (control and experimental) each of six animal, after being provided with 2% cholesterol diet. Rats of the experimental group were each given 600 mg/kg of S.

Assessment of artificial neural network performance and exponential regression in prediction of effective rainfall

According to the current water crisis and spend more than 94 percent of water in agriculture the mechanized irrigation systems, and revised the actual plant water estimation are needed it is facilitate to predict rainfall in the growing season. In the design of irrigation systems should be noted that the total rainfall occurred was not available for plant and part of the rainfall runoff and part of it penetrate to soil and only part of it that is called effective rainfall is able to disappear plant water stress and influence plant growing.

On determining thermal conductivity of brown coals before and after their heat treatment in electric arc plasma

The paper presents the results of the study of the thermal conductivity of brown coal deposit "Okinoklyuchevskoye" of 0.1-1 mm fraction being processed in an electric arc plasma. To solve the problem there have been experimentally determined actual, apparent and bulk density of coal, as well as its porosity. The research was carried out by calculation based on the model of alternative structures by Misnara, using Fritz B. and H. Moser data. The data received reveal the structural uniformity of the coke residue (activated charcoal), i.e. the degree of its graphitizability.

Changing status of tribal women in Bastar District of Chhattisgarh

Human occupational activities in the stubbs creek forest reserves (SCFR) of akwa ibom state: impacts and implications on socio-economic environment

Akwa Ibom State with a total land area of 8412.0km2 is endowed with Stubbs Greek Forest Reserve (SCFR). The exploitation of the SCFR has reached an alarming proportion principally due to human occupational activities such as farming, lumbering, oil exploration, road and residential constructions. Relying specifically on field-based data from 240 respondents from three Local Government Areas in Akwa Ibom State, it has been observed that, continuous exploitation of the SCFR through human occupational concerns has resulted in the destruction and loss of human habitat and bio-diversity.
