Double Facial Nerve Trunk Emerged from the Stylomastoid Foramen and Petrotympanic Fissure: A Case Report

There are several studies concerning branches of the facial nerve, but we encountered less information about the trunk of the facial nerve in the literature. During the routine dissection of a 65-yr-old Caucasian male cadaver, double facial nerve trunk emerged from the stylomastoid foramen and petrotympanic fissure were encountered. Because of an extremely rare variation, we presented this case report. In addition this cadaver had two buccal plexuses. These plexuses and other branches were formed to structures like to polygon. These anatomic peculiarities were described, photographed and illustrated. Finally, magnetic resonance imaging was performed by using 1.5T scanner to this cadaver. The facial nerve trunk can be damaged during surgical procedures of the parotid gland tumours and submandibular region. Surgeons who are willing to operate on this area should be aware of the possible anatomical variations of the facial nerve trunk

THE RELATIONSHIP BETWEEN ANKLE MORPHOLOGY AND OSTEOCHONDRITIS DISSECANS OF TALUS

The purpose of this study is to describe the impact of ankle morphology to osteochondritis dissecans of talus formation. 26 patients with traumatic osteochondritis dissecans, 30 patients with non-traumatic osteochondritis dissecans and 37 patients with normal ankle as a control group included to study. Two investigators conducted measurements. We used 5 morphological parameters. We found found a significant difference in the patients with osteochondritis dissecans of medial talus. In the traumatic group the average age of the patients was 42 years and number of males 2,7 times than females. Patients of non-traumatic group older than traumatic and in contrast to traumatic group, number of females were 1,72 times than males. Age distributions and also gender distribution of the groups were significantly different from each other. Traumatic osteochondritis dissecans occurs in younger ages. It might be correlated to higher trauma incidence of males in this age group

Effect of nitrogen and planting dates on yield and yield components of head lettuce grown in soilless culture

The objective of this study was to determine the effect of different N applications with different planting dates on yield, leaf nutrients and some quality parameters of head lettuce (Lactuva saliva L. var. capitata cv. Bombola) grown in substrate-culture. The experiment was conducted in an unheated plastic polyethylene (PE) covered greenhouses of the Ege University Bayindir Vocational Training School in Turkey during the winter-early spring of 2016-2017. The trial was established in a randomized block design (RBD) with four replications. In this study, the development and yields of iceberg seedlings, grown at four different planting dates (8th and 23th of February; 9th and 23th of March), were determined under three different nitrogen applications (75, 150, and 250 mg N L-1). The results showed that the studied traits were affected by the treatments, so that the highest yield (334g head(-1)), number of leaves (39), DW (436%), and Vit.C (13.45%) was obtained on 23th of Feb. (second planting date). According of Nitrogen applications, highest yield (399g/head), number of leaves (40), DW (5.13%) was found in 150 mg L-1 N application. Overall results indicated that the most suitable cultivation period for iceberg was February, which was the first (8th Feb.) planting date in this current study. Second planting date of experiment (23rd Feb.) was also acceptable for the suitable cultivation. It was also concluded that 75-150 mg N L(-1 )applications could be recommended for the nutrition of iceberg in soilless culture.This study was supported by the Ege University Science and Technology Centre EBILTEM (Project no: BAMYO 2015-002).Ege University Science and Technology Centre EBILTEM [BAMYO 2015-002

Experimental Comparison of GaN-Fet Based Motor Drives for High Switching Frequencies

IEEE 3rd Global Power, Energy and Communication Conference (IEEE GPECOM) -- OCT 05-08, 2021 -- ELECTR NETWORKAs a new semiconductor switch, GaN-Fet provides a high switching frequency so that total harmonic distortion (THD) can be reduced in addition to rotor loss and noise level in motor drive applications. In this study, a GaN-FET based three phases inverter design is analyzed for an induction motor. The space vector PWM (SVPWM) method is used for two high switching frequencies, 50 kHz and 100 kHz. To implement this high-frequency application, a real-time system is designed with TI-BoostXL three phases GaN-Inverter and a low-cost microprocessor, STM32F407-VG is used. The system is modeled in MATLAB/Simulink environment. The embedded control algorithm is designed with STM32-Cube and Keil-MDK software with Hardware Abstraction Layer (HAL) and digital signal processing (DSP) libraries with floating-point unit (FPU).IEEE,Nevsehir Haci Bektas Veli Univ,IEEE Ind Applicat Soc,IEEE Ind Elect Soc,IEEE Power Elect Soc,IEEE Power ; Energy Soc,Univ Nova Lisboa,Univ Salerno,Univ Palerm
