Abstract: A compact (0.15 λ l ×0.15 λ l ×0.01λ l ) triple band antenna for WiMAX/ WLAN application is proposed. Compactness and multiband operation is accomplished by utilizing E-type unit cell Defected Ground Structure (DGS) in conjunction with H-shaped slot. The main advantages of the proposed E-type unit cell DGS structure is that each unit cell independently control a set of bands (i.e. Upper E-type unit cell DGS structure controls 2.56 and 3.64 GHz, while lower E-type unit cell controls the band at 5.8GHz). The antenna shows the resonance at 2.56 (lower WiMAX), 3.64 (middle WiMAX) and 5.8 (WLAN) with fractional bandwidth of about 5.44 % (2.5-2.64 GHz), 5.77% (3.53-3.74 GHz) and 1.5% (5.735.82 GHz). Good pattern and impedance matching is obtained at the targeted frequencies.

Abstract: Aims And Objectives- To determine the surgical prole and outcome of patients with surgical drains following MATERIALS AND METHODS- Study design: observational study Period of study: december 2020 to January 2022 sample size :79 .All patients undergoing elective abdominal surgeries w INCLUSION CRITERIA: EXCLUSION ith drain placement CRITERIA: 1.Age <18yrs 2.Patients with pre-existing infection at surgical site 2.Patients with pre-existing infection at surgical site Results & Conclusion-Obese patients undergoing elective laparotomy suffer from local wound complications such as seroma, hematoma, pain at wound site, wound dehiscence, and surgical site infections. These complications occur because of increased subcutaneous fat thickness, poorly controlled bleeding points in subcutaneous plane. These will lead to increased morbidity for the obese patients and prolonged hospital stay. In this study, we have observed that there is positive correlation between SSI and BMI, with the Rate of SSI was seen more in BMI >25 as compared to BMI <25, there is increased wound complication associated with increase in age because of varied factors mentioned above. We observed less wound complications in female patients compared to males due to the probable benecial effect of estrogen on wound healing. Also we observed that patients with higher BMI are more prone for wound complications thus further increasing their length of hospital stay
