PURPOSE Endotoxins, also called lipopolysaccharides (LPS), are major contaminants found in commercially available proteins or biologically active substances, which often complicate study of the biological effects of the main ingredient. The presence of small amounts of endotoxin in recombinant protein preparations can cause side effects in host organism such as endotoxin shock, tissue injury, a...

The paper presents results of laboratory experiments focused on the efficiency of polychlorinated biphenyls (PCBs) removal by electroremediation, pyrolysis and incineration decontamination methods. The experiments were carried out using soil contaminated with heavy metals and PCBs. Different process parameters were changed during the experiments in order to achieve maximum removal efficiency. C...

Among all the challenges for foreground detection, we focus on detection of ghosts caused by the starting or stopping of objects. We propose a fast and effective method for ghost detection that compares the similarity between the edges of the detected foreground objects and those of the current frame based on object-level knowledge of moving objects. Finally we demonstrate the performance of gh...

BACKGROUND On an average 1 litre of blood is lost during Caesarean Section. Many variable techniques have been tried to reduce this blood loss. Many study trials have shown the spontaneous delivery of placenta method to be superior over manual method because of reduced intra operative blood loss and reduced incidence of post operative endometritis. The main objective of our study was to compare...

Dental implant has been restoring the function and esthetics lost from missing tooth. However, biomechanical implant complications are the major cause of failing implants. Therefore, implant removal is one of the indispensable dental treatments. The 70-year-old male and 66-year-old female who had discomfort on posterior implants region came to Department of Periodontology. Conventional method u...

An experiment was conducted using 336 White Leghorn hens (60 wk of age) randomly assigned to one of four treatments that consisted of feed removal for 4 or 10 d or no feed removal with ad libitum access to 95% corn or 95% wheat middlings molt diets that contained supplemental minerals and vitamins. At the end of the 4- or 10-d feed removal period, hens on these treatments were provided with the...

Image deblurring is a discrete ill-posed problem. This paper discusses cascadic multilevel methods designed for the restoration of images that have been contaminated by nonsymmetric blur and noise. Prolongation is carried out by nonlinear edge-preserving and noise-reducing operators, while restrictions are determined by weighted local least-squares approximation. The restoration problem is on e...

Objective: The aim is to compare various fully automated methods for reducing ocular artifacts from EEG recordings. Methods: Seven automated methods including regression, six component-based methods for reducing ocular artifacts have been applied to 36 data sets from two different labs. The influence of various noise sources is analyzed and the ratio between corrected and uncorrected EEG spectr...
