In this study, activated carbon (AC) and magnetic (MAC) were prepared from Dalbergia sissoo sawdust for the removal of antibiotic Azithromycin (AZM) aqueous solution. The effect initial concentration, contact time, pH, adsorbent dosage, temperature investigated both adsorbents. optimum AZM pH adsorbents dosages found to be 80 mg/L, 120 min, 6 7 (pH, respectively, AC MAC), 0.1 g (for respectivel...

Wireless Local Area Network (WLAN) is widely used today because of its mobility and ease of deployment. Providing complete security to the WLAN users is a challenge due to the open nature and undefined boundaries of the wireless networks. This paper is intended to protect the 802.11 WLAN environments from Medium Access Control (MAC) layer Denial of Service (DoS) attacks especially, the deauthen...

This paper presents Multiply and Accumulate (MAC) unit design using Vedic Multiplier, which is based on Urdhva Tiryagbhyam Sutra. The paper emphasizes an efficient 32-bit MAC architecture along with 8-bit and 16-bit versions and results are presented in comparison with conventional architectures. The efficiency in terms of area and speed of proposed MAC unit architecture is observed through red...

OBJECTIVE Evaluate the incidence of mycobacterial disease and the colonization of the respiratory and gastrointestinal tracts by Mycobacterium avium complex (MAC) bacteria in AIDS patients. METHODS INCLUSION CRITERIA HIV-positive individuals with at least one CD(4)(+) count < 100 cells/mm(3). EXCLUSION CRITERIA Mycobacterial disease and MAC prophylaxis. Stool, sputum, and blood cultures ...

WLANs have become increasingly popular and widely deployed. The MAC protocol is one of the important technology of the WLANs and affects communication efficiency directly. In this paper, focusing on MAC protocol, we propose a novel protocol that network nodes dynamically optimize their backoff process to achieve high throughput in multi-hop wireless networks. Distributed model MAC protocol has ...

The security of two message authentication code (MAC) algorithms is considered: the MD5-based envelope method (RFC 1828), and the banking standard MAA (ISO 8731–2). Customization of a general MAC forgery attack allows improvements in both cases. For the envelope method, the forgery attack is extended to allow key recovery; for example, a 128-bit key can be recovered using 2 known text-MAC pairs...

We develop and evaluate a new method for estimating and optimizing various performance metrics of mobile wireless multi-hop networks, including MANETs. The method utilizes approximate (throughput) loss model that couples the physical, MAC and routing layers effects. The model provides quantitative statistical relations between the loss parameters that are used to characterize multiuser interfer...

High-density glasses of neodymio-cadmium lead borate chemical composition xNd2O3/20CdO/20PbO/(57-x)B2O3/3Na2O, where (0 (0Nd) ? x 5 (5Nd) wt%) have been fabricated by a melt quenching process. Physical, structure properties as well gamma-radiation and neutron shielding effectiveness in wide photon energy range 0.015–15 MeV examined. The amorphous nature xNd-glasses was confirmed, there lack the...
