A polysaccharide producing strain ofBacillus licheniformis was isolated from exudate of raffia palm,Raffia vinifera. The optimum conditions for growth and polysaccharide production have been investigated and established. No appreciable polysaccharide was formed on glucose. It grew best in Czapek-Dox media with sucrose as the carbon source. The(More)
Intraosseous calvarial meningiomas, defined as meningiomas confined to the skull with no epidural or subcutaneous component, are rare and usually exhibit osteoblastic activity. We present a case of a primary intraosseous meningioma in the right frontal bone that presented radiologically as a solitary lytic skull lesion and was completely excised. The lesion(More)
We report a case of epidermal inclusion cyst of penis in a five-year-old boy, who had presented to the outpatient department of our hospital. Epidermal inclusion cysts are benign lesions that can develop in any part of the body. However, the finding of an epidermal inclusion cyst in the penis is rare. The child was operated and discharged uneventfully. The(More)
Acoustic schwannomas usually present with gradually progressive unilateral sensorineural hearing loss. As the tumor enlarges, symptoms and signs develop when the adjacent cranial nerves, cerebelhim, and/or brainstem become compressed. Rarely, acoustic tumors present with acute subarachnoid or intratumoral hemorrhage. Of the 12 cases of acoustic schwannoma(More)
In recent years, digital watermarking techniques have been proposed to protect the copyright of multimedia data. Different watermarking schemes have been suggested for images. This paper proposes a watermarking algorithm based on image segmentation and Discrete Cosine Transform (DCT). The image is first segmented using Expectation Maximization (EM)(More)
The bacteriostatic and bactericidal activity of ampicillin when combined at ten different ratios with either streptomycin or chloramphenicol against Pseudomonas aeruginosa has been investigated. Synergistic bacteriostatic effect was obtained with all ampicillin/streptomycin combinations and 9 ratios of ampicillin/chloramphenicol combinations. The highest(More)
A method involving an overlay inoculum agar and antibiotic susceptibility discs in the determination of synergy of gentamicin and disc antibiotics against clinical isolates of Pseudomonas aeruginosa has been described. Gentamicin combinations with carbenicillin showed synergism against all test isolates. Combinations containing fosfomycin had indifferent(More)
We present a case of complete renal duplex with H-shaped double ureter opening into the bladder with 2 separate orifices. It is an extremely rare variety of renal duplex which was reported only once in the literature. Fifty-four-year-old male presented to our department with right renal pain. Noncontrast CT revealed stone midthird right ureter with duplex(More)
1. The area investigated embraces Suez harbour, El Shalloufa, Geneva, Kebret (at the Bitter Lakes), Devresoir and Tossoum pilotage stations. It extends about 75 km along the Suez Canal. 2. The Suez-Geneva section is poorly fouled, mainly due to the high silt content of the water. At Suez the standing crop of fouling reached its lowest value in the Canal(More)
