A low-profile single-ridge waveguide magic-T is proposed as a combination of two T-junctions at an X band. A slot coupling technique is used to reduce the component dimensions in the E-plane, thus leading to a low profile. The device can assume two configurations by arranging the sum and difference ports in the same or opposite direction, an attractive feature in the design of beamforming networks with complex routing. A magic-T prototype is fabricated using laser powder bed fusion additive manufacturing techniques. Good agreement between simulations and measurements is found.
A fatality due to ingestion of triazolam and promazine is reported. Triazolam is a benzodiazepine widely prescribed as a hypnotic drug for the treatment of sleep disorders. Promazine is a neuroleptic drug. There is no previous evidence in the literature of death due to an overdose related to the contemporaneous intake of these two drugs. In this report the authors present the case of a 76-year-old woman who was found deceased at home with no evidence of trauma or asphyxia; near the body several empty pharmaceutical boxes containing triazolam and promazine were noticed. Toxicological analyses were performed and drug levels measured by means of gas chromatography coupled with mass spectrometry. The triazolam concentration in each specimen was as follows: blood 1100ng/ml; gastric content 1300ng/ml; the promazine concentration in blood and in gastric content was 3450ng/ml and 5800ng/ ml respectively. Based on the autopsy findings, patient history and toxicological results, the cause of death was determined to be acute intoxication due to the effect of triazolam and promazine and the manner of suicide.
An original in-line coaxial-to-rectangular waveguide transition including stepped ridged sections is presented. This device differs from the state of the art because of the coaxial inner conductor not being in electrical contact with the ridge, leading to considerable mechanical advantages. In addition to this, capacitive coupling can extend the bandwidth even with a few matching sections when compared with the traditional counterpart presenting DC contact with the first ridge. An ultra-compact transition is designed, manufactured, and tested in back-to-back configuration. From measured data, a return loss better than 20 dB on a bandwidth of 1.27 GHz (12.2%) is observed in this configuration. An average insertion loss of 0.11 dB can be derived for the standalone transition.
Abstract Background Mucinous adenocarcinoma of the prostate (MACP) is one of the rarest variants of prostatic neoplasm, with more aggressive behavior than non-mucinous prostatic cancer. Previous studies suggested that these tumors exhibit different imaging magnetic resonance imaging (MRI) features compared with those of non-mucinous adenocarcinoma of the prostate upon which the conventional PIRADS v2.1 is based. To the best of our knowledge, this case series is the first to describe the multiparametric magnetic resonance imaging features of the MACP. Results We presented two cases of biopsy proven mucinous adenocarcinoma of the prostate studied with multiparametric MRI. In both cases, diagnosis was late because of the different MRI features of MACP than those of the more common adenocarcinoma of the prostate. In both mpMRI, MACP appears to be hyperintense on T2WI, there was not a significant decrease in diffusivity in ADC maps and it exhibits early enhancement in DCE-MRI; the septa resulted in hypointense on T2WI compared to the PZ Conclusions According to our experience, the conventional PIRADS v2.1 score is not suitable for mucinous prostate adenocarcinoma. MACP appears to be hyperintense on T2WI, has a lower ADC value, and exhibits early enhancement in DCE-MRI; the septa are usually hypointense on T2WI compared to the PZ. It is imperative for radiologists and urologists to be cognizant of this rare variant of prostate cancer to promptly identify and diagnose it, thereby preventing any diagnostic delays.
We report a case of a calf-related fatality on a farm. The victim was a 60-year-old man who was possibly attempting to sexually approach the animal from behind when he was struck by it, sustaining fatal blunt injuries, mostly to the thorax. This case is reported because of its rarity and because of the particular circumstances of death. Fatal trauma associated with bovines is rare on the whole, and when it does occur it is usually caused by kicking or pushing during regular agricultural activity. Although the cause of death in our case could be determined, the circumstances and the manner of death remain speculative to some degree.
In this work, an H-plane and an E-plane single-ridge waveguide T-junction exhibiting compact size and broadband performance are presented. Thanks to these features the proposed devices turn out to be key components for the implementation of high-performance multilayer antenna beam-forming networks. Effectiveness and suitability of such T-junctions are demonstrated through the design of a broadband array antenna feeding network. The presented components operate at Ku band, nevertheless the adopted architectures are fully scalable to other frequency band of interest.
Objectives Accidental falls are among the leading hospitals’ adverse events, with incidence ranging from 2 to 20 events per 1.000 days/patients. The objective of this study is to assess the relationship between in-hospital falls and the score of 3 DEPendence and Clinical-Social Fragility indexes. Methods A monocentric case-control study was conducted by retrieving data of in-hospital patients from the electronic health records. Results Significant differences between the mean scores at the hospital admission and discharge were found. The BRASS scale mean (SD) values at the admission and at the discharge were also significantly higher in cases of in-hospital falls: at the admission 10.2 (±7.7) in cases versus 7.0 (±8.0) in controls ( P = 0.003); at the discharge 10.0 (±6.4) versus 6.7 (±7.5) ( P = 0.001). Barthel index mean (SD) scores also presented statistically significant differences: at the admission 60.3 (±40.6) in cases versus 76.0 (±34.8) in controls ( P = 0.003); at discharge 51.3 (±34.9) versus 73.3 (±35.2) ( P = 0.000). Odds ratios were as follows: for Barthel index 2.37 (95% CI, 1.28–4.39; P = 0.003); for Index of Caring Complexity 1.45 (95% CI, 0.72–2.91, P = 0. 255); for BRASS index 1.95 (95% CI, 1.03–3.70, P = 0.026). With BRASS index, the area under the curve was 0.667 (95% CI, 0.595–0.740), thus indicating a moderate predictive power of the scale. Conclusions The use of only Conley scale—despite its sensitivity and specificity—is not enough to fully address this need because of the multiple and heterogeneous factors that predispose to in-hospital falls. Therefore, the combination of multiple tools should be recommended.
