Shorted TEM horn antenna for GPR applications

, 2016
In this study, a novel TEM horn antenna design is introduced for Ground Penetrating Radar (GPR) applications. TEM horn antennas are mostly used in GPR for the advantages of high gain and power capability and wide bandwidth.

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

UWB compact TEM ridged horn antenna

, 2014
In this paper, compact version of partially dielectric loaded TEM Ridged Horn (PDTEM-RHA- 13) antenna is presented for ultra-wide band applications. Since outer size of antenna is approximately 2.5 times reduced compared 0.4-14 GHz version, operation ...

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Bioerosion traces in bones reveal an increase in ethological diversity in the insect exploitation of carcasses in the late Triassic

The Anatomical Record, EarlyView.
Abstract This study presents the first detailed description of bioerosion traces produced by insects in bones from the Santa Cruz Sequence (early Carnian, Santa Maria Supersequence, Brazil). An array of traces is reported, consisting of notches, a tube, trails of grooves attributed to the ichnotaxon Osteocallis mandibulus and ornamented depressions ...
