Title: INFLUENCE OF NARINGENIN ON PERFORMANCE, MEAT QUALITY AND ANTIOXIDANT STATUS OF BROILERS Authors: A.Abbas; M. F. Iqbal; A. Riaz; M.U. Hasan; M. Shoaib; A.A. Mian; K. Ishaq Abstract: The growth promoting antioxidant and meat quality related effects of naringenin in broilers were evaluated in the current study. One hundred and eighty day-older broiler chicks (Hubbard) were randomly selected to four treatment groups containing three replicates of 15 birds each. Feed supplemented with 0, 5, 10 and 20 mg/Kg naringenin was allotted to the experimental treatment groups (T1, T2, T3 and T4) respectively. An increased weight gain and better feed conversion ratio (FCR) (P<0.05) was observed by using naringenin at the rate of 10 mg/kg of feed, during the whole xperiment period. The results of sensory evaluation showed that the breast meat was better (P<0.05) in flavour, mouth feeling and likeness in T2, T3 and T4 as compare to T1. The plasma GSHPx was significantly (P<0.05) increased on day 21 and 42 in treated groups as compare to control group. The MDA also showed significant difference between naringenin treated and control groups on day 21 with lower values for the birds treated with higher doses of naringenin. A significantly higher levels of SOD and TAOC were observed in chicken treated with naringenin at 21 or 42 days of age.

Title: TRACE MODEL FOR CYCLIC BEHAVIOR IN WIRELESS LANS Authors: M. Bukhsh; S. Abdullah; M.N.Asghar Abstract: For the estimation of cycle time in WLANs different parameters were used to analyze the cyclic behavior like packet loss cycle, successful packet cycle and collision cycle. This paper proposes a model to control all the node activities, contention status, including collision probability, successful packet information, packet etransmission, packet loss information, cyclic behavior and throughput with comprehensive consideration of node heterogeneity. The simulation was performed for evaluation of proposed trace model and contention control scheme. The proposed model achieved significant results compared to existing schemes which did not systematically considered node heterogeneity. The results verified that the packet loss rate was 0%, collision probability was 7% and successful packet rate was 100%. The results varied due to the variance of successful sending of MAC Protocol Data Unit (MPDUs), total MPDU losses, total MPDU collision and the cyclic behavior.

Title: ANTIMICROBIAL AND ANTIOXIDANT SCREENING OF Gardenia tetrasperma Authors: M. Ajaib; M. Latif; S.A. Mirza; Aziz-Ul-Hassan; M.A. Iqbal; Z. Khan Abstract: Antimicrobial and antioxidant activities of an unexplored medicinal plant, i.e., Gardenia tetrasperma Roxb. was investigated. The antimicrobial potential of extracts of G. tetrasperma was determined using human athogenic four bacteria and two fungi. The maximum antibacterial potential was recorded, in chloroform extract of leaf, i.e., 91.66±0.4 mm zone of inhibition against E. coli. Chloroform extract of leaves showed 62±1.1 mm zone of inhibition against S. aureus. The methanolic leaf extract showed maximum potential against A.niger and F. solani with the values 42.42±1.5 and 36.22±1.11 mm respectively, whereas the lowest value showed by water extract of the leaf against F.solani, i.e. 16.43±1.37. The methanolic extract of seed also showed satisfactory results against F. solani, i.e. 42±1.75. In seed extracts lowest value was revealed by the water macerates of seeds i.e. 12.33±0.8. The MIC assay was performed for further study which presented the significant MIC value i.e. 0.02±0.1 at 0.8 mg/mL of leaf extract against E. coli where as it was 0.02±0. 9 at 0.2 mg/mL against A. niger. Antioxidant potential was determined using DPPH scavenging potential. The uppermost value of % DPPH was observed as s95.51±1.7 at 500 μL concentration in petroleum ether extract of bark. The maximum values of total antioxidant activity (TAA) were 1.29±0.11 and 1.19±0.5 in methanolic extract of bark and etroleum ether macerates of leaf respectively. Total Phenolic Content (TPC) was 1.702±0.3 and 1.07±3.7 in Petroleum ether macerates of leaf and water macerates of seed, respectively.

EXTENDED TINY ENCRYPTION ALGORITHM EQUIPPED WITH ARABIC SCRIPT (AXTEA)

Title: EXTENDED TINY ENCRYPTION ALGORITHM EQUIPPED WITH ARABIC SCRIPT (AXTEA) Authors: S.Z. Naseem; S. Nazir; M.S. Sarfraz; U. Shoaib; A. Altaf Abstract: Cryptography is a science that deals with secret writing. Now a days, every programming language, browsers, and famous databases support the UTF-8 code. Therefore, it is easier to store Arabic script languages into the database. Most encryption algorithms are used to convert plain text to cipher, whereas cipher is usually in the same language with the text being ciphered or in special characters. In this paper, we enhanced an algorithm (XTEA) and converted English plain text to Arabic script language (for instance, Arabic, Urdu, and Persian) using Extended Tiny Encryption Algorithm (XTEA). The proposed algorithm was implemented in PHP, and the results show that the resultant cipher was more secure. It enhanced the security of data because the medium of the ciphered text was not same as plain text. We named our proposed algorithm as Arabic Extended Tiny Encryption Algorithm (AXTEA).
