Modeling Probability of Path Loss for DSDV, OLSR and DYMO above 802.11 and 802.11p

This paper presents path loss model along with framework for probability distribution function for VANETs. Furthermore, we simulate three routing protocols Destination Sequenced Distance Vector (DSDV), Optimized Link State Routing (OLSR) and Dynamic MANET On-demand (DYMO) in NS-2 to evaluate and compare their performance using two Mac-layer Protocols 802.11 and 802.11p. A novel approach of this work is modifications in existing parameters to achieve high efficiency. After extensive simulations, we observe that DSDV out performs with 802.11p while DYMO gives best performance with 802.11.Comment: IEEE 8th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA'13), Compiegne, Franc

Soybean (Glycine max L) genotype and environment interaction effect on yield and other related traits

Open Access International JournalTo evaluate genetic variability of five soybean genotypes, and assess genotype × environment effect on seed yield and yield related traits. Study Design: Split-plot, replicated three times. Genotypes were fixed effect while plots (main 60 m² and subplot 12 m²) were random effects. The sub-plot consists of 4 rows 5 m long with 60 cm and 10 cm inter and intra-row spacing. Place and Duration: El Gantra, Range and Pasture Farm in Sennar State of the Sudan during 2009 and 2010 cropping season. Methodology: Five soybean genotypes NA 5009 RG; TGx 1904-6F, TGx 1740-2F, TGx 1937-1F and Soja were evaluated. A strain of Rhizobium japonicum was used for inoculation at a rate of 10 g per kg of soybean seed using a sugary solution in 2009. Inoculation was not carried out due to the assumption that the field had the remnant of inoculum effect in 2010. All the recommended soybean agronomic practices were equally applied. Number of days to 50% flowering was recorded on plot basis when almost half of the sub-plot flowers. Ten plants were randomly selected on plot basis to quantify these traits: Plant height was measured as from ground surface to the base of meri-stem of the mother plant. Number of branches was computed as an average count of branches per plant. Leaf area was computed using Iamauti [12] empirical relationship. The first pod height was measured at full bloom. Number of seeds per pod was counted at physiological maturity of the crop. 100-seed weight was determined randomly from a seed bulk using a digital weighing machine. Seed yield was quantified after harvest and converted into kg/hectare. Results: The effect of genotype (G), environment (E) and G × E interactions on pod number per plant; plant height, first pod height, number of branches per plant, leaf area, number of days to 50% flowering and seed yield were found significant at P=0.05. The highest mean seed yield was obtained from TGx 1937-1F (0.98 t/ha). Beside TGx 1740-2F, TGx 1904-6F and Soja were significantly higher than NA 5009 RG in all environments for seed yield. TGx 1937-1F was an intermediate maturing and best in terms of number of pods per plant, number of branches per plant, and leaf area. Correlation coefficient for seed yield showed significant association with days to 50% flowering and leaf area. Conclusion: The best genotype for seed yield across the environments was TGx 1937-1F and TGx 1740-2F, TGx1904-6F and Soja were intermediate and NA 5009 RG was the least. Thus, partitioning G × E into adaptability and phenotypic stability will positively address the information gap on association of traits to yield

Liver Adiposity and Metabolic Profile in Individuals with Chronic Spinal Cord Injury

Purpose. To quantify liver adiposity using magnetic resonance imaging (MRI) and to determine its association with metabolic profile in men with spinal cord injury (SCI). Materials and Methods. MRI analysis of liver adiposity by fat signal fraction (FSF) and visceral adipose tissue (VAT) was completed on twenty participants. Intravenous glucose tolerance test was conducted to measure glucose effectiveness (g) and insulin sensitivity (i ). Lipid panel, fasting glucose, glycated hemoglobin (HbA1c), and inflammatory cytokines were also analyzed. Results. Average hepatic FSF was 3.7% ± 2.1. FSF was positively related to TG, non-HDL-C, fasting glucose, HbA1c, VAT, and tumor necrosis factor alpha (TNF-). FSF was negatively related to i and testosterone. FSF was positively related to VAT ( = 0.48, = 0.032) and TNF- ( = 0.51, = 0.016) independent of age, level of injury (LOI), and time since injury (TSI). The associations between FSF and metabolic profile were independent of VAT. Conclusions. MRI noninvasively estimated hepatic adiposity in men with chronic SCI. FSF was associated with dysfunction in metabolic profile, central adiposity, and inflammation. Importantly, liver adiposity influenced metabolic profile independently of VAT. These findings highlight the significance of quantifying liver adiposity after SCI to attenuate the development of metabolic disorders

PREPARATION AND EVALUATION OF VITAMIN E ADJUVANTED OIL EMULSIFIED INFECTIOUS BRONCHITIS EXPERIMENTAL VACCINE

The present study was conducted to prepare oil emulsified (OE) infectious bronchitis (IB) experimental vaccines. The vaccines were prepared using the vaccinal strain H-120 Infectious Bonchitis virus (IBV). The virus was cultivated in 9-day old embryonated eggs via allantoic cavity route. Allantoic-amniotic fluid (AAF) was collected and inactivated with formalin @ 0.12%. Water in oil emulsion was prepared by adding one part of AAF to four parts of mineral oil containing water phase (Tween 80) and oil phase (Span 80) surfactants. Hydrophile lypohile balance (HLB) of the emulsion was maintained at 7.0. Two oil emulsified experimental vaccines were prepared. Vaccine-I was prepared without vitamin E and Vaccine-II with vitamin E (300 mg/ml). A total of 120 day-old broiler breeder chickens were divided into 4 groups, A, B, C, and D, each having 30 birds. At the age of 21 days, experimental Vaccine-I, experimental vaccine-II and commercial IB killed (H-120) vaccine were inoculated @ 0.5 ml in the birds of groups A, B and C, respectively. Group D was maintained as nonvaccinated control. Efficacy of the vaccines was evaluated on the basis of humoral immune response (haemagglutination inhibition antibody titres) against IB in the four groups. The seven weeks cumulative mean antibody titres (CMT) of each group were calculated. The highest CMT was observed in group B (130), followed by group C (69), group A (58) and group D (17). Statistical analysis showed that haemagglutination inhibition (HI) antibody titres in group B (vaccine- II) were significantly higher than those of groups A, B and C (P< 0.05)
