We present ∼1.5 Mars Years (MY) of ozone vertical profiles, covering LS = 163° in MY34 to 320° MY35, a period which includes the 2018 global dust storm. Since April 2018, Ultraviolet and Visible Spectrometer channel Nadir Occultation for Discovery (NOMAD) instrument aboard ExoMars Trace Gas Orbiter has observed vertical, latitudinal seasonal distributions ozone. Around perihelion, relative abun...

The NOMAD-UVIS instrument on board the ExoMars Trace Gas Orbiter has been investigating Martian atmosphere with occultation technique since April 2018. Here, we analyze almost two Mars Years of ozone vertical distributions acquired at day-night terminator. retrievals proved more difficult than expected due to spurious detections caused by instrumental effects, high dust content, and very low va...

عصاره گیاه رزماری، 4 برابر آنتی­اکسیدان‌­های مصنوعی مانند BHT و BHA خاصیت آنتی­اکسیدانی دارد. رزمارینیک اسید نه تنها به دلیل خواص قوی مورد توجه است بلکه خصوصیات ضدالتهابی، ضدتوموری، ضدباکتریایی، ضدویروسی ضدسرطانی را نیز در پژوهش‌­های مختلف نشان داده است. هدف از این تحقیق، بررسی اثرات دما، زمان، pH غلظت پرتودیده نشان‌دارسازی آن با رادیوایزوتوپ گالیم-67 عنوان یک عامل تصویربرداری وضوح بالا برای تو...

Yb2Si2O7/Si environmental barrier coatings (EBCs) were produced by air plasma spray (APS) and low-pressure (LPPS) processes. The phase composition, microstructure, bonding strength of APS LPPS EBCs investigated. Thermal cycling tests performed in steam atmosphere respectively at 1316 °C for both EBCs. There is no coating failure after 900 cycles. In contrast, have an average life 576 cycles a t...

The lack of adequate stereo coverage and where available, lengthy processing time, various artefacts, unsatisfactory quality complexity automating the selection best set parameters, have long been big barriers for large-area planetary 3D mapping. In this paper, we propose a deep learning-based solution, called MADNet (Multi-scale generative Adversarial u-net with Dense convolutional up-projecti...

The paper presents observations of gravity wave-induced temperature disturbances in the Martian atmosphere obtained with mid-infrared (MIR) spectrometer, a channel Atmospheric Chemistry Suite instrument on board Trace Gas Orbiter (ACS/TGO). Solar occultation measurements absorption band at 2.7 m were used for retrieving density and profiles between heights 20 160 km vertical resolution sufficie...

Thermal tides in the Martian atmosphere are analyzed using temperature profiles retrieved from nadir observations obtained by TIRVIM Fourier-spectrometer, part of Atmospheric Chemistry Suite onboard ExoMars Trace Gas Orbiter. The data is selected near northern summer solstice at solar longitude (LS) 75°–105° Year 35. have a full local time coverage, which enables analyses daily anomalies. obser...

We present vertical profiles of temperature and density from solar occultation (SO) observations by the “Nadir Occultation for Mars Discovery” (NOMAD) spectrometer on board Trace Gas Orbiter during its first operational year, which covered second half Year 34. used calibrated transmittance spectra in 380 scans, apply an in-house pre-processing to clean data systematics. Temperature CO2 up about...

Gadolinium zirconate (GZ) is an attractive material for thermal barrier coatings (TBCs). However, a single layer GZ coating has poor cycling life compared to Yttria Stabilized Zirconia (YSZ). In this study, Solution Precursor High Velocity Oxy-Fuel (SP-HVOF) spray was used produce double GZ/YSZ TBC and the performance with YSZ TBC. The temperature behaviour of solution precursor studied, splat ...
