The construction of an accurate approximation of the-pseudospectrum of a matrix by means of the standard grid method is a very demanding computational task. In this paper, we describe Cobra, a domain-based method for the computation of pseudospectra that combines predictor corrector path following with a one-dimensional grid. The algorithm o€ers large and medium grain parallelism and becomes pa...

The role of the complement system in containment of feline leukemia virus infection was studied by cobra venom factor treatment of feline leukemia virus-immune cats. One to three weeks after cobra venom factor treatment, an increase in viral antigen in marrow myelomonocytic cells and circulating immune complexes was noted. Prevention of reactivation of feline leukemia virus infection may in par...

Natural hemagglutinin activity against vertebrate erythrocytes is present in the hemolymph of the cockroach Blabarus craniifer. The hemagglutinin titer against rabbit erythrocytes is high, whereas sheep and horse red cells agglutinate weakly. Hemagglutinin activity was depressed by the complement inhibitor, cobra venom factor. Cockroach hemagglutinin is heat-labile; all activity is destroyed by...

The effects of tourniquet application were prospectively studied in 36 hospitalized patients who developed neurotoxic symptoms after bites by the Philippine cobra (Naja naja philippinensis). Tourniquets had been applied in 94% of cases and delayed the onset of symptoms. Four patients were asymptomatic prior to the release of their tourniquet and in 11 patients symptoms worsened precipitously. M...

Snake bite was known as one of the most important public health concerns world wild. Respiratory and cardiac problems and destruction of endothelium system occurs as a result of snake bite. Some proteins and peptides in snake venom have potential for drug discovery studies. According to the important role of cell adhesion and angiogenesis in cancer development, identification of new therapeutic...

Workers’ remittances constitute one of the most important sources of external finance for many developing countries. Although it shows a decreasing trend in recent years, Egypt after 1970s with her regular and massive labor migration to abroad has been still one of the gainer countries on remittances across the world. Empirical studies that implemented for various countries reveal workers’ ...

Organizations nowadays focus on, not implementing ERP systems, but also leveraging ERP systems as part of their digital strategy. They holistically address people, processes, and technology for a digital transformation. Meanwhile, higher education institutions (HEIs) are also facing an imperative need for the implementation of modern technologies to stay competitive and differentiate them as an...

The practice of Egyptian psychiatrists emigrating to high-income countries is not a recent phenomenon. Egyptian doctors have long travelled in search of training and education and to better their standards of living. The debate continues. What effective measures can be taken to reduce the brain drain, or at least its effect on Egyptian mental health services?

"Process Re-engineering" is a concept that has been in operation in the manufacturing industry for a number of years. Often, it involves moving an organisation or industry away from its traditionally functional base to process based structures. It is however a relatively new concept in the UK construction industry. This paper will explore the concept of process re-engineering, evaluate its oppo...
