The competency of garlic and pennywort to improve broiler chicken growth and influence intestinal microbial communities and fatty acid composition of breast meat were studied. Two hundred forty, "day-old" chicks were randomly allocated to 4 treatment groups consisting of 6 replications of 10 chicks in each pen. The groups were assigned to receive treatment diets as follows: i) basal diet (control), ii) basal diet plus 0.5% garlic powder (GP), iii) basal diet plus 0.5% pennywort powder (PW) and iv) 0.002% virginiamycin (VM). Birds were killed at day 42 and intestinal samples were collected to assess for Lactobacillus and Escherichia coli. The pectoralis profundus from chicken breast samples was obtained from 10 birds from each treatment group on day 42 and frozen at $-20^{\circ}C$ for further analyses. Fatty acid profile of breast muscles was determined using gas liquid chromatography. Feed intake and weight gain of broilers fed with GP, PW, and VM were significantly higher (p<0.05) compared to control. Feeding chicks GP, PW, and VM significantly reduced Escherichia coli count (p<0.05) while Lactobacillus spp count were significantly higher (p<0.05) in the gut when compared to control group on day 42. Supplemented diet containing pennywort increased the C18:3n-3 fatty acid composition of chickens' breast muscle. Garlic and pennywort may be useful in modulating broiler guts as they control the enteropathogens that help to utilize feed efficiently. This subsequently enhances the growth performances of broiler chickens.

Efficiency Enhancement of Wireless Power Transfer with Optimum Coupling Mechanism for Mid-range Operation

Anowar, Tanbir Ibne,Kumar, Narendra,Ramiah, Harikrishnan,Reza, Ahmed Wasif The Korean Institute of Electrical Engineers 2017 Journal of Electrical Engineering & Technology Vol.8 No.1

This paper depicts the design, implementation and analysis of efficient resonant based wireless power transfer (WPT) technique using three magnetic coupled coils. This work is suitable for mid ranged device due to small form factor while minimizing the loading effect. A multi turned loop size resonator is exploited for both the transmitter and receiver for longer distance. In this paper, class-E power amplifier (class-E PA) is introduced with an optimum power tracking mechanism of WPT system to enhance the power capability at mid-range with a flat gain. A robust method of finding optimum distance is derived with an experimental analysis of the designed system. In this method, the load sensitive issue of WPT is resolved by tuning coupling coefficient at considerable distances. Our designed PA with a drain efficiency of 77.8% for a maximum output of 5W is used with adopted tuning technique that improves the overall WPT system performance by 3 dB at various operating points.

A New Optimized Localized Technique of CG Return Stroke Lightning Channel in Forest

Kabir, Homayun,Kanesan, Jeevan,Reza, Ahmed Wasif,Ramiah, Harikrishnan,Dimyati, Kaharudin The Korean Institute of Electrical Engineers 2015 Journal of Electrical Engineering & Technology Vol.10 No.6

Localization of lightning strike point (LSP) in the forest is modeled to mitigate the forest fire damage. Though forest fire ignited by lightning rarely happens, its damage on the forest is grievousness. Therefore, predicting accurate location of LSP becomes crucial in order to control the forest fire. In this paper, we proposed a new hybrid localization algorithm by combining the received signal strength (RSS) and the received signal strength ratio (RSSR) to improve the accuracy by mitigating the environmental effect of lightning strike location in the forest. The proposed hybrid algorithm employs antenna theory (AT) model of cloud-to-ground (CG) return stroke lightning channel to forecast the location of the lightning strike. The obtained results show that the proposed hybrid algorithm achieves better location accuracy compared to the existing RSS method for predicting the lightning strike location considering additive white Gaussian noise (AWGN) environment.

Background: To compare the outcomes in a group of patients with Budd-Chiari syndrome (BCS) managed by percutaneous recanalization with a group of patients who were managed by medical therapy alone.Methods: We retrieved the hospital records of 37 patients with BCS admitted to our facility between 2004 to 2017 and identified 24 patients (male:female = 10:14; mean age, 32.7 ± 12.5 years) who underwent percutaneous recanalization. Remaining thirteen patients (male:female = 3:10; mean age, 36.77 ± 14.71 years), were managed by medical therapy. Technical and clinical results, complications, and primary patency of percutane-ous recanalization were analyzed. Overall and symptom-free survival rates, the frequency of symptom recurrence, and the number of readmissions for recurrent symptoms were analyzed in both interventional treatment and medical therapy groups.Results: Technical success for recanalization of hepatic vein/inferior venecava by angioplasty ± stenting was achieved in 22 patients (22/24, 91.7%). Clinical success was achieved in 19 patients (19/24, 79.2%). Overall survival for patients who underwent percutaneous recanalization at 1 year and five years was 87.0% and 87.0% and for patients with medical therapy was 90.1% and 45.5%, respectively (P = 0.710). Symptom-free survival for patients who underwent percutaneous recanalization at 1 year and five year was 93.3% and 81.7% and for patients with medical therapy was 26.0% and 0%, respectively (P < 0.001). In the intervention group, 4 patients (4/24, 16.7%) were admitted for recurrent symptoms (median number of read-missions 1, range: 1–2) whereas in medically managed patients 9 patients (9/13, 69.2%) were readmitted (median number of readmissions, 2; range, 1–5) (P = 0.003).Conclusion: There was no statistically significant difference in overall survival of patients managed with percutaneous recanalization and medical therapy. Percutaneous recanalization had definite benefit in terms of fewer recurrent symptoms and hospital admissions, hence should be performed whenever technically feasible.
