Digital's PATHWORKS for DOS version 4.1 personal computer integration software includes two network virtual device drivers for the Microsoft Windows environment. These drivers allow Windows applications operating in a protected processor mode and standard DOS applications in a virtual machine to concurrently access services designed to run in real mode under the DOS operating system. The networ...

Uma série de cetonas e ésteres α,β-insaturados β-amino ésteres, 4a-h e 6a-d, derivados de α-amino ácidos foi obtida a partir dos cloridratos dos α-amino ésteres 2a-d e dos compostos 1,3-dicarbonílicos 3a,b e 5 em presença de trietilamina. Estes compostos foram preparados empregando energia de microondas, sem uso de solvente, utilizando como suporte sólido K-10 ou KSF e também foram efetuadas re...

Diversity-oriented synthesis (DOS) is an important field involving the synthesis of libraries of diverse small molecules for applications including biological screening. The last decade has witnessed major progress in the field, with continued emphasis on structural and functional diversity for DOS library construction. A number of recent reviews have updated the community on this topic, includ...

The partial occupation numbers and density of states (DOS), and the total DOS at the Fermi level are calculated as a function of reduced atomic volume for bcc and fcc alkali metals employing the linearmuffin-tin-orbital (LMTO) method. By means of the abrupt changes obtained in the partial and total DOS values at the Fermi level, good agreement with regard to experiment were found in predicting ...

Availability requires that computer systems function normally without loss of resources to legitimate users. One of the most challenging issues to availability is the denial-ofservice (DoS) attack. DoS attacks constitute one of the major threats and among the hardest security problems in today’s Internet. The main aim of a DoS is the disruption of services by attempting to limit access to a mac...

To clarify the genetic relationships among the Lidia breed lineages and two main Portuguese Lidia bovine populations, Casta Portuguesa and Brava dos Açores, 24 autosomal microsatellites were analyzed in 120 samples. Brava dos Açores showed the highest observed and expected heterozygosity (0.73 and 0.70, respectively) while Casta Portuguesa showed the lowest observed and expected heterozygosity ...

Denial of Service (DoS) is a prevalent threat in today’s networks because DoS attacks are easy to launch, while defending a network resource against them is disproportionately difficult. Despite the extensive research in recent years, DoS attacks continue to harm, as the attackers adapt to the newer protection mechanisms. For this reason, we start our survey with a historical timeline of DoS in...

Aminoglycoside antibiotics represent a classical group of antimicrobials first discovered in the 1940s. Due to their ototoxic and nephrotoxic side effects, they are typically only used against Gram negative bacteria which have become resistant to other therapeutics. One family of aminoglycosides includes such compounds as butirosin, ribostamycin, neomycin, and kanamycin, amongst others. The com...
