We observed few important facts that concerns with the new proposal of knapsack cipher 0/255, recently published by Pham [1]. The author claimed that the time complexity for solving new improved trapdoor knapsack is O(256). In this paper, we show that the knapsack cipher 0/255 can be solved in the same time that is required for solving the basic knapsack-cipher proposed by Merkle and Hellman [2...

Pulmonary tuberculosis must be suspected in patients with respiratory symptoms longer than 2–3 weeks. Immunosuppression may modify the clinical and radiological presentation. The chest X-ray is highly suggestive of tuberculosis (TB), but is occasionally atypical. The complex radiological tests (CT scan, MRI) are more useful in extrapulmonary TB. At least 3 consecutive representative samples fro...

Staphylococcus aureus has long been recognized as a major cause of hospital-acquired infection. Over the last decade, methicillin-resistant S. aureus (MRSA) strains have become endemic in hospitals worldwide, including in the UK. Accordingly, the frequency of MRSA isolation has increased dramatically. Glycopeptides, such as vancomycin, are often the therapeutic drugs of choice for serious MRSA ...
