INTRODUCTION The use of bone grafts in orthopedic, maxillofacial and dental surgery has been growing. Nevertheless, both fresh autografts and frozen allografts have limitations, and therefore, alternative synthetic or natural biomaterials, such as processed and lyophilized bovine bone graft have been developed. OBJECTIVE To evaluate in vitro and in vivo biocompatibility of lyophilized bovine ...

The present study was focused on the microbial community of soil collected from industrial areas of Mysore district. The collected soil samples from industrial areas were analyzed for pH, Temperature, Electrical conductivity, Moisture content, Water holding capacity and heavy metal analysis such as Iron (Fe), Copper (Cu), Zinc (Zn), Nickel (Ni), Chromium (Cr) Lead (Pb), and Cadmium (Cd) and by ...

Objective: The present study investigates the diversity, and distribution of harmful microbes in sediments and groundwater of Tuticorin Corporation. The faecal pollution indicators such as, Total coliform bacteria, Faecal coliform bacteria, Escherichia coli, Faecal streptococci were investigated in the sediments and groundwater samples from 12 locations in the study area. Methods: Groundwater a...

The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) were determined by gas chromatography equipped with a mass spectrometry detector in 105 topsoil samples from an industrial area around Bohai Bay, Tianjin in the North of China. Results demonstrated that concentrations of PAHs in 104 soil samples from this area ranged from 68.7 to 5,590 ng g(-1) dry weight with a mean of summation ...

As part of a multidisciplinary health effects study, the nephrotoxicity of complex industrial waste mixtures was assessed. Adult, male Fischer 344 rats were gavaged with samples of complex industrial waste and nephrotoxicity evaluated 24 hr later. Of the 10 tested samples, 4 produced increased absolute or relative kidney weight, or both, coupled with a statistically significant alteration in at...

Background & objectives: Nowadays, consumers are demanding more accurate and clear food information than ever before, and meat products are no exception. Given the relatively high cost of raw meat, the possibility of adulteration is not unthinkable. The importance of detecting fraud meat products is due to the inclusion of other types of meat or cheap carcass components or the non-compliance of...

This paper presents a multidisciplinary study that identifies and applies unsupervised connectionist models in conjunction with modelling systems, in order to determine optimal conditions to perform automated drilling tasks. This industrial problem is defined by a data set relayed through sensors situated on a robotic drill that is used to build industrial warehouses. The results of the study a...

This paper examines the impact of industrial agglomeration on productivity and firm employment in Guangdong province, China. As the firstly opened area in China, Guangdong gained most benefits from the economic reform by attracting FDI and expanding trade. Furthermore, due to its adjacency to Hong Kong, a core-periphery mechanism with significant agglomeration effects, as described in spatial e...

Fifty-seven typical surface soils and 108 deeper soils were collected from five former industrial sites in Beijing and concentrations of total Hg (SigmaHg) as well as pH, total carbon (TC), total nitrogen (TN), total sulfur, and dissolved organic carbon concentrations determined. The mean concentration of SigmaHg in surface soils was significantly greater than background concentrations in the v...

Industrial clusters have received considerable attention from economists and industrial analysts. The main purpose of this paper is to contribute to the understanding of the driving forces behind the growth of industrial clusters. Another core viewpoint anchored in this paper is that national competitive advantages can be achieved by industrial clusters. We examine the impacts of and determine ...
