Assessing the Amazon Cloud Suitability for CLARREO's Computational Needs

In this document we compare the performance of the Amazon Web Services (AWS), also known as Amazon Cloud, with the CLARREO (Climate Absolute Radiance and Refractivity Observatory) cluster and assess its suitability for computational needs of the CLARREO mission. A benchmark executable to process one month and one year of PARASOL (Polarization and Anistropy of Reflectances for Atmospheric Sciences coupled with Observations from a Lidar) data was used. With the optimal AWS configuration, adequate data-processing times, comparable to the CLARREO cluster, were found. The assessment of alternatives to the CLARREO cluster continues and several options, such as a NASA-based cluster, are being considered

Earth Science Data Fusion with Event Building Approach

Objectives of the NASA Information And Data System (NAIADS) project are to develop a prototype of a conceptually new middleware framework to modernize and significantly improve efficiency of the Earth Science data fusion, big data processing and analytics. The key components of the NAIADS include: Service Oriented Architecture (SOA) multi-lingual framework, multi-sensor coincident data Predictor, fast into-memory data Staging, multi-sensor data-Event Builder, complete data-Event streaming (a work flow with minimized IO), on-line data processing control and analytics services. The NAIADS project is leveraging CLARA framework, developed in Jefferson Lab, and integrated with the ZeroMQ messaging library. The science services are prototyped and incorporated into the system. Merging the SCIAMACHY Level-1 observations and MODIS/Terra Level-2 (Clouds and Aerosols) data products, and ECMWF re- analysis will be used for NAIADS demonstration and performance tests in compute Cloud and Cluster environments

Dynamics of Students’ Ideas about the Work in the Arctic

The article presents the results of the longitudinal study, which was conducted during the years 2018 and 2019 and aimed to identify changes in the assessment of certain socio-economic and psychological aspects of working and living in the Arctic by students of different courses. Special attention was paid to such factors as transport and social infrastructure, working conditions, wages, social guarantees, the climate, health status, the psychological atmosphere in a team, the possibility of self-realization. The sample population at the first stage of the study was 618 people (2018). After bringing the 2019-sample in line with the parameters of the 2018-sample, 337 students’ questionnaires were analyzed in the second stage. The main research method was a questionnaire survey, the results of which were statistically processed using such methods as the qualitative analysis of the empirical data, the analysis of primary statistics, the analysis of contingency tables (for nominative data), comparative and variance analyses (for metric data). The software “Statistica” was used for statistical processing. The main results of the study, first of all, include an increase in internal motivation to work in the Arctic among the students from the 2019-sample: they, to a greater extent, compared to junior students, emphasize the need for personal interest in work. The analysis of the answers of the respondents in year 2019 showed an increasing role of wages and the understanding of difficult climate conditions and the associated difficulties of living in deciding whether to work in the Arctic. In other words, the longitudinal study, implemented during the years 2018 and 2019, recorded the obvious increase in motivation, as well as the increase in the requirements for working and living conditions in the harsh Arctic climate among the surveyed students during their transition to the senior year

ESR-SPECTROSCOPY OF IRRADIATED FOOD

This paper describes the using ESR- spectroscopy in order to control doses of irradiated food at customs and local production areas

ESR-DOSIMETRY OF IONIZING RADIATION

The abstract is devoted to the method of measurement of absorbed dose of ionizing radiation with the help of a new type of coherent superheterodyne ESR-spetrcometer developed in UrFU and industrialized by NPO Avtomatika. It is based on the determination of calibration curve for the device and comparison of its spectra with reference data when samples are irradiated with accelerated electrons, x-ray radiation and alpha-radiation.Авторы благодарят профессора И.И.

Triplet dynamics and charge carrier trapping in triplet-emitter doped conjugated polymers

Phosphorescent (Ph) properties and charge carrier trapping have been studied in conjugated polymer CNPPP with incorporated red-emitting Btp(2)Ir(acac) metal-organic complex by time-resolved photoluminescence and thermally-stimulated luminescence (TSL) techniques. We characterized intrinsic Ph of CNPPP matrix and dynamics of triplet excitations of Btp(2)Ir(acac) confined by the polymer host. Combined studies of time and intensity dependence of guest Ph have demonstrated that the observed decrease in the Ph efficiency in CNPPP:Btp(2)Ir(acac) system at increasing excitation intensity is dominated by mutual host-guest triplet-triplet annihilation. We observed Ph spectral diffusion effects at 10 wt.% of Btp(2)Ir(acac) dispersed in a polymer matrix, which is a proof for the triplet excitons migration though the manifold of triplet-emitter sites, and which governs the Ph concentration quenching effect. TSL measurements have provided direct evidence that the triplet-emitter molecules create a deep charge trap in the conjugated polymer and allowed trap characterization. (c) 2009 Elsevier B.V.

EPR spectroscopy of spices

From 01 January 2017 you enter the interstate standard GOST 33271-2015 “Dry Spices, herbs and vegetable seasonings. Manual exposure in order to combat pathogens and other microorganisms” which States that the absorbed dose of radiation to the spices should be from 3 to 30 kGy. The study found that before the introduction of permissive legislative framework in the consumer market of Russia there are irradiated food products (chili, ground chili, ground spicy chili, black pepper). For radiation monitoring of food safety, we used the method of electron paramagnetic resonance (EPR), which allows quickly and with a high degree of reliability to establish the fact of irradiation. It is established that all samples of spices irradiated with dose of 12 kGy (technology radappertization) gave typical spectra of the signals established by the method of electron paramagnetic resonance in the domestic EPR spectrometer, the intensity, amplitude and peak width of the EPR signal of samples of spices with the increase of irradiation dose increases. It is proven that repeated exposure no effect accumulation. Integration with 2017 Russia in the global practi ce of using radiation technologies of processing of food products and food raw materials with the purpose of extending shelf life confirms the need for a data Bank on the radiation sensitivity of various food products to determine the optimal doses and the eff ect of radiation doses on the shelf life and quality of products
