Calibration issues for a three-band microwave radiometric system with background noise compensation
Authors: Fedoseeva Elena V. , Shchukin Georgy G. , Rostokin Ilya N.
Published: May 2020

For microwave radiometric remote sensing systems in natural environments, the important issue is calibration, i.e. determination-one correspondence of values of the output signal value of the brightness temperature of the sensed region, the largest of which evaluated physical parameters. Microwave radiometric systems operate under the influence of external interference, for example, background noise – radiothermal radiation of the space surrounding the system, received through the scattering region of the antenna pattern. This article examines the influence of background noise on the external calibration of a microwave radiometric system (based on an external “deterministic” noise source) and analyzes the conditions for performing such calibration in a system with compensation for the influence of background noise. The analysis of the output signal of the microwave radiometric system showed a significant influence of background noise on the parameter determined during calibration of the system – the beginning of the receiver scale, due to a change in the value of the contribution of background noise to the output signal when forming two reference levels during calibration from two angular directions. The possibility of reducing the interference effect of background noise on the results of measurements in a microwave radiometric system with a special two-channel antenna operating on two modes of a circular waveguide, with the formation of an additional compensation signal at the antenna output, is shown. The proposed version of the analytical evaluation of the degree of compensation of the influence of background noise on the output differential signal of the system and presents results of its application to numerical analysis of error in external calibration a tri-band microwave radiometric system with compensation of background noise when receiving thermal radiation onthe total aperture of the antenna.

To ensure the uniformity of measurements and ensure metrological traceability of the measurement results in the field of ensuring the uniformity of measurements state regulation, including in the areas of healthcare and pharmaceuticals, reference materials of the composition, properties and structure of substances are needed. Currently, the Federal Information Fund of the Russian Federation has approximately 9000 reference materials, among which only about 30 reference materials are intended for use in pharmaceuticals and medicine. This amount is clearly not enough for full metrological support of these areas. This article describes the main stages and results of research and development of starting pharmaceutical substances reference materials of amphotericin B, natamycin, olivomycin A. The main substances of the created reference materials are identified. Mass fractions of related compounds, residual organic solvents and inorganic impurities (iron cations and heavy metals) were determined. The results of the work were used to confirm the reference materials types of the starting pharmaceutical substances amphotericin B, natamycin, olivomycin A.

Published: May 2020

The objectives of this research was to evaluate the inheritance of albino slayer phenotype in brushmouth (Hypostomus plecostomus, Linn 1758) through the crosses and reproduction performance. The crossing scheme consisted of reciprocal crosses between albino slayer and albino non slayer (SN, NS) and between albino slayer (SS), each spawning in pairs (1:1) with three replications and twice spawning. The fish used in this study were brushmouth fish (Hypostomus sp.) albino Slayer males 9.07 ± 0.5 cm, albino slayer females 8.96 ± 0.4 cm, albino non slayer males 8.87 ± 0.17 cm, and albino non slayer female 8.86 ± 0.16 cm. Slayer phenotype category was identified based on the caudal length fin with 4.43 ± 0.64 cm. Parameters determined included the phenotype distribution of albino slayer, total number of eggs, fertilization rate, hatching rate and survival rate. The results showed that all crossing schemes produced four phenotypes classes including normal slayer, normal non slayer, albino slayer and albino non slayer. The slayer phenotype of albino brushmouth was highest percentage (75%) in crossing with male albino slayer (SN, SS) and highest number of eggs, while the reciprocal crossing with female albino slayer (NS) produced albino slayer 55% and lower egg count. The ratio of tail fin length to body length in albino slayer phenotype was lower than normal phenotype of broom fish. The fertilization and hatching rates were not significantly different in all crosses; however the number of eggs decreased in the second spawning. The similar phenotype cross between albino slayer phenotypes (SS) resulted the best average of survival rate (92%).

Thermodynamics and transport properties of the supercritical fluid of metals
Authors: KHOMKIN ALEXANDER L. , SHUMIKHIN ALEKSEY S.
Published: May 2020

The proposed model allows to calculate the composition, thermodynamic and transport properties of the supercritical metal vapors within unified approach. The model includes atoms, immersed in jellium, and thermally ionized electrons and ions. The jellium is the part of the bound states electron density. The density of electron jellium increases with the compression of atomic gas and does not depend on temperature directly. At compression, the electrical conductivity passes through the minimum from the conductivity of thermal electrons to the conductivity of electrons of jellium accordingly. Calculations of the equation of state and the electrical conductivity of supercritical metal vapors agree well with physical and numerical experimental data.
A short-time physics problem in superconductivity: Stability against quench
Authors: REISS HARALD
Published: May 2020

This paper investigates the stability problem of superconductors against quench. Numerical Finite Element simulations are applied to calculate the distribution of transient temperature, critical current density and transport current in the conductor cross-section under a disturbance, here flux flow losses. Contrary to standard stability models, the focus of the paper is on situations very close to the superconducting/normal conducting phase transition. The obtained results demonstrate it is not realistic, even in thin films, to assume uniform conductor temperature under a disturbance. A method is suggested on how to predict the time and position of a quench when it is expected to occur in the conductor cross-section. Quench starts locally. Application of a microscopic stability model allows to describe continuous, not abrupt but very fast break-down of transport current in situations close to the phase transition.

Recent studies on thermophysical properties of metallic alloys with PROSPECT: Excess properties to construct a solution model
Authors: FUKUYAMA H. , WATANABE M. , ADACHI M.
Published: May 2020

We have developed the system PROSPECT for measuring thermophysical properties at high temperature. Precise thermophysical measurements provide accurate excess functions, which represent non-ideality of solutions. We use excess functions to discuss solution models on the basis of electronic structure and thermodynamics. Pd-Fe systems show positive excess volume VE with negative excess Gibbs energy GE. The phase diagrams of these systems have common features with those of other Pd-X and Pt-X systems (where X is Fe, Ni, Co, or Cu), which means they all have order-disorder transitions. The correlation between VE and GE is discussed in terms of the electronic structure of the alloys, and an energy diagram is proposed to understand this correlation. The excess heat capacity CpE of Fe-Ni melts is positive over a whole composition range and a wide temperature range. We estimate the temperature dependences of the excess enthalpy HE and excess entropy SE of Fe-Ni melts from CpE. The Lupis-Elliott rule is satisfied for HE and SE with positive CpE.

From Paper, to Microform, to Digital?
Authors: McLeod Donald W.
Published: May 2020

The ArQuives: Canada’s LGBTQ2+ Library and Archives, founded in 1973, holds one of the largest collections of queer serials in the world. The more than 10,000 titles are mostly in paper, but formats have been evolving. Beginning in the 1980s, the ArQuives participated in small microfilming projects. Microfilming of the collection greatly increased in 2005, when Primary Source Microfilm (PSM) undertook a large project to film a portion of the collection, resulting in 211 reels devoted to international gay and lesbian periodicals and newsletters. The PSM project was later repurposed and expanded by Gale Cengage, beginning in 2015, and forms part of its Archives of Sexuality and Gender online product. This paper examines the evolution of the ArQuives’ serials holdings from paper to microform to digital formats and explores recent in-house digitization efforts and future prospects for expanding access to these materials.

Historianopetuksen tavoitteet nykyisessä lukiossa ovat laajat ja keskittyvät sisältöjen, historian taitojen sekä demokratiakansalaisuuden oppimiseen. Tässä artikkelissa tarkastelemme, millaisia arviointimenetelmiä lukion historianopettajat käyttävät ja kuinka ne suhteutuvat opettajien näkemyksiin historian opetuksen tavoitteista. Tutkimus perustuu vuonna 2016 kerättyyn kyselyaineistoon, joka kerättiin lukion historianopettajilta (N = 151). Kysyimme heidän näkemyksiään lukion historianopetuksen tavoitteista, heidän käyttämistään opetusmenetelmistä sekä arviointitavoista. Tulosten mukaan opettajat painottavat sisältötietojen hallintaa riippumatta siitä, mitä tavoitetta he pitävät opetuksessa tärkeimpänä. Tuloksissa näkyy kuitenkin myös eroja muun muassa suhteessa tiedonmuodostuksen periaatteiden hallintaan. Tulokset kertovat opetuskulttuurista, jossa historianopetukselle määriteltyjä laajoja tavoitteita pyritään soveltamaan käytäntöön laaja-alaisesti. Artikkelin lopussa esitämme konkreettisia toimia, kuinka historianopetuksen tavoitteiden ja arvioinnin välistä suhdetta voidaan entisestään tiivistää.

Tässä artikkelissa tutkitaan perusopetuksen, aikuisten perusopetuksen ja lukion opetussuunnitelmaperusteita Peter Seixasin historianopetuksen orientaatioita koskevan teorian pohjalta. Seixasin mukaan historianopetuksessa voidaan hahmottaa kolme erilaista orientaatiota: kollektiivisen muistin ja identiteetin vahvistamiseen tähtäävä historianopetus, tiedonalaperusteinen historianopetus ja postmoderni historianopetus. Kaikki käsittelemämme opetussuunnitelmaperusteet ovat lähtökohtaisesti tiedonalapainotteiseen opetustraditioon perustuvia ja korostavat siten kriittisen kansalaisen ihannetta. Vahvimmin tiedonalaperusteisuus näkyy perusopetuksen opetussuunnitelman perusteissa ja heikoimmin aikuisten perusopetuksen opetussuunnitelmaperusteissa. Kaikkien opetussuunnitelmien pohjalta nousee esiin vaihtelevin painotuksin läntisen, eurooppalaisen ja kansallisen identiteetin vahvistamiseen tähtääviä elementtejä. Vahvimmin nämä pyrkimykset näkyvät aikuisten perusopetuksen ja lukion opetussuunnitelmissa. Perusopetuksen opetussuunnitelma sen sijaan tarjoaa opettajille laajemmat mahdollisuudet tiedonalapainotteiseen ja opiskelijoiden yksilölliset identiteetit huomioivaan historianopetukseen. Postmodernin historianopetuksen orientaatioon kytkettävissä olevia elementtejä on löydettävissä sekä perusopetuksen että lukion opetussuunnitelmien historiallisen tiedon käytön ymmärtämistä koskevissa tavoitteenasetteluissa. Postmoderni lähestymistapa voisi tarjota tulevaisuudessa tutkimisen arvoisia mahdollisuuksia. Sen kautta kulttuurisesti moninaisen yhteiskunnan menneisyyskertomuksia voitaisiin käsitellä lähtökohtaisesti yhdenvertaisina, mutta samaan aikaan myös pohjimmiltaan poliittisina ja tulevaisuuteen suuntaavina. Toisaalta rajat ylittävien ongelmien leimaamassa maailmassa historianopetusta olisi perusteltua jäsentää entistä vahvemmin myös globaalien teemojen ympärille.

The effect of using visual aids in cloze tests testing grammar at B1 level: A quasi-experimental study
Authors: BALLIDAĞ Sezgin
Published: May 2020

A considerable amount of literature has been published about the use of visual aids in language classrooms to see if they foster learning or classroom participation. Visuals have been used in test format for years, as well; however, there is a dearth of research to indicate how effective the presence and the type of visuals in testing grammar through multiple-choice cloze tests. To close the gap in the literature, the current study aims to identify the effect of using visual aids, specifically real pictures, diagrams, and no pictures in a cloze test on students’ grades and test completion times. This is a quasi-experimental, quantitative study. The data was collected through cloze tests that tested grammar via multiple-choice items within a context about synesthesia. The sample consisted of 64 B1 level preparatory school students (27 females, 37 males) studying at a state university in Istanbul. The participants were from different majors. The data were analyzed through SPSS. The results revealed a significant difference between the visual types and students’ completion time of the texts. It took different groups between 2 minutes to 7 minutes to complete the test. The real picture group spent the most time (M= 4.45), which was followed by the diagram group (M= 3.47) and no visual test group (M=3.45). However, no significant differences were found between the grades of the students who took tests with different visuals.
