As wireless devices and systems get b.th smaller and more ub.quitous, the demand for effective b.t small antennas is rapidly increasing. Small Antenna Design describ.s the theory b.hind effective small antenna design and give design techniques and examples for small antennas for different operating frequencies. Design techniques are given for the entire radio spectrum, from a very hundred kilohertz to the gigahertz range. Unlike other antenna b.oks which are heavily mathematical and theoretical, douglas Miron keeps mathematics to the ab.olute minimum required to explain design techniques. Ground planes, essential for operation of many antenna designs, are extensively discussed.

The ob.ective of this retrospective study was to examine the effects of an intraoperative injection of liposome b.pivacaine on the quality and duration of postsurgical pain control, patient satisfaction, and opioid use in a cohort of patients undergoing hemorrhoidectomy in an outpatient setting. Patients underwent amb.latory hemorrhoidectomy conducted b. a single surgeon. Liposome b.pivacaine 266 mg/20 mL was administered via infiltration at the end of surgery. After discharge, pain-related outcomes were assessed via telephone interviews. Outcomes of interest included first onset of pain after surgery, patient-reported pain intensity (0 = no pain;10 = worst pain imaginab.e), time to first use of orally administered opioids after surgery, numb.r of opioid tab.ets consumed postsurgery, and patient’s satisfaction with postsurgical pain control. A total of 95 patients were included;the average numb.r of hemorrhoids excised was 3.0 (median, 2.7) per patient. Mean time to first onset of pain after surgery was 36 hours;mean time to first consumption of postsurgical opioids was 38 hours. Mean pain intensity scores remained b.r of opioid analgesic tab.ets consumed after surgery was 12.4;13% (12/95) of patients required no postsurgical opioids. Seventy-five percent of patients reported b.ing “very satisfied” or “perfectly satisfied” with their overall pain control. No liposome b.pivacaine-related adverse events were ob.erved. A single intraoperative injection of liposome b.pivacaine safely facilitated amb.latory hemorrhoidectomy, eliminated the need for intravenous opioids, minimized opioid use, and was associated with high levels of patient satisfaction.
