This paper presents a narrow notch band, exible, wearable ultra-wideband antenna built on a jeans substrate. Prior to designing the antenna, the dielectric properties of the jeans substrate are experimentally investigated. The effects of antenna shape and substrate loss characteristics on resonant performances are discussed with reference to the notch characteristics. The proposed antenna is shaped like a cumulative rugged element, with two identical legs. The investigation of the designed antenna shows the operating frequency ranges (S11 < -10 dB) in 2.4{4.2 GHz and 5.86{10.7 GHz bands with notch properties in telemetry/mobile communications (4.4{4.99 GHz) and WLAN (5.15{5.85 GHz) band. Additionally, the prototype is investigated under on-body conditions. Measured results are also included for the validation of the designed prototype. [ABSTRACT FROM AUTHOR]

The present study was conducted to study the shelf life evaluation of raw chicken meat emulsion incorporated with clove powder, ginger and garlic paste at refrigerated storage (4±1°C). Four different batches of chicken meat emulsion i.e. C = Control (without natural preservatives), T1 = 0.2% clove powder, T2 = 3% ginger paste and T3 = 2% garlic paste, were analyzed during refrigerated storage (4±1°C) of 9 days under aerobic packaging. Throughout the storage, free fatty acids and peroxide value was significantly higher (P < 0.05) in control than T1, T2 and T3 batches. Among the treated batches, garlic paste batch (T3) showed significantly (P < 0.05) lower free fatty acid values during the storage period. Thiobarbituric acid value (TBA) did not vary significantly among the treated batches but clove powder (T1) maintained lowest TBA value till the end of storage. 1, 1-diphenyl-2-picrylhydrazyl (DPPH % inhibition) radical scavenging activity and 2-2-azinobis-3ethylbenthiazoline-6-sulphonic acid (ABTS % inhibition) radical scavenging activity was significantly higher (P < 0.05) in T1 batch as compared to control, T2 and T3 batches throughout the storage interval. L* value did not vary significantly among different batches, while a* value was found to be significantly higher (P < 0.05) in T1 batch. Percentage metmyoglobin was significantly lower for T1 batch than control, T2 and T3 batches during storage. Colour and odour scores of T1 batch were significantly higher (P < 0.05) than control, T2 and T3 batches. Standard plate count was significantly higher (P < 0.05) in control than T1, T2 and T3 batches. Throughout the storage period, comparatively lower values of both standard plate count and coliform counts were detected in T1 batch than control, T2 and T3 batches. From this comparative study of natural preservatives, it was concluded that 0.2% clove powder could be utilized effectively as antioxidant and antimicrobial in raw chicken meat emulsion.

BACKGROUND RESULTS CONCLUSION The first evidence of blood biochemical and proteomic changes in slow‐growing broiler chicken subjected to ritual slaughter like halal (HS) and jhatka (JS) without stunning and commercial slaughter with electrical stunning (ES) was decoded.Significant stress indicators like cortisol and triiodothyronine were markedly elevated in JS birds, whereas increased (P < 0.05) levels of lactate dehydrogenase and creatine kinase were observed in JS and ES birds. Two‐dimensional gel electrophoresis coupled to MALDI‐TOF MS elucidated the overabundance of glyceraldehyde‐3‐phosphate dehydrogenase and l‐lactate dehydrogenase that are positively correlated with stress in JS broilers. Bioinformatic analysis explored the multifaceted landscape of molecular functions.The study has uncovered that ritual slaughter performed without stunning against commercial slaughter with ES practices elicit varying levels of stress as evident from blood biochemistry and novel protein markers. © 2024 Society of Chemical Industry.

An H‐shaped dielectric resonator array antenna is presented for wideband applications. The proposed antenna is excited by slot feed mechanism and investigated experimentally. The antenna covers the frequency ranges from 1.41 to 2.59 GHz, and 4.73 to 6.06 GHz with the corresponding impedance bandwidth of 59% and 24.65%, respectively. The simulation results fulfill the bandwidth requirements of IEEE 802.11a/b/g (2.4‐2.484 GHz/5.15‐5.35 GHz/5.725‐5.825 GHz) for Wireless local area network (WLAN) applications. The proposed antenna has simple structure, easy to fabricate and its measured radiation pattern shows a reliable performance in the desired operating bands. [ABSTRACT FROM AUTHOR]
