Aristolochi
Morphological characteristics
Grass vine. Root cylindrical. The stem is weak and hairless. Leaves alternate; petiole long l-2cm, tender; leaf ovate-triangular, oblong-ovate or serpentine, 3-6cm long, base 1.5-3.5cm wide, apex obtuse or shortly acuminate, base cordate, bilateral The lobes are round, sagging or slightly expanded; the basal veins are 5-7, and the veins at all levels are evident on both sides. Flower solitary or 2 clusters born in leaf axils; pedicels long l-1.5cm; trichomes triangular, easy to fall off; tepals 3-5.5cm long, base sinusoidally globose, narrowing into a long tube, tube mouth expanded into Funnel-shaped, yellow-green, with purple patches at the mouth and glandular hairs on the inside; very short on one side of the ankle, and gradually extending into a tongue on the other; tongues ovate-lanceolate, apically blunt; anthers adnate to The column is near the base; the chamber is cylindrical, 6 edges; the apex of the column is 6-lobed, slightly papillary, and the lobes are blunt at the tip, forming a wavy ring downward. The capsule is subglobose, apex rounded and slightly concave, with 6 edges. When mature, the base begins to crack along the space 6-lobes; the fruit stem is 2.5-5cm long and often torn into 6 pieces. Seeds are flat, blunt triangles, and white lines with broad wings. Flowering from July to August, fruiting from September to October.
Hearing aid manufacturers strive to optimize their wireless hearing aid offerings both in terms of connection reliability as well as power efficiency. Variance across patients and listening conditions can make optimizing wireless hearing aid systems a complex process.
Factors such as connection distance, proximity of reflective surfaces, interference from other wireless devices, and energy loss through body absorption must all be factored into the hearing aid design. For example, indoor wireless performance may be very different from wireless performance experienced outdoors, where the only reflective surface may be the ground on which the hearing aid user is standing. Furthermore, individual differences in body geometry increase the variability that wireless engineers must account for when designing a system that provides each user with a consistent and reliable experience.
As awareness of wireless hearing technology grows, hearing healthcare professionals may notice an uptick in long-term safety concerns. Consumers should be confident knowing that wireless hearing aids are safe and strictly regulated medical devices that meet governmental wireless communication standards in addition to those set forth for medical devices.
