Abstract
Mid-infrared (MIR) images of the Galactic center show extended gas and dust features along with bright infrared sources (IRS). Some of these dust features are a part of ionized clumpy streamers orbiting Sgr A*, known as the mini-spiral. We present their proper motions over a 12 yr time period and report their flux densities in N-band filters and derive their spectral indices. The observations were carried out by VISIR at the ESO’s Very Large Telescope. High-pass filtering led to the detection of several resolved filaments and clumps along the mini-spiral. Each source was fit by a 2D Gaussian profile to determine the offsets and aperture sizes. We perform aperture photometry to extract fluxes in two different bands. We present the proper motions of the largest consistent set of resolved and reliably determined sources. In addition to stellar orbital motions, we identify a stream-like motion of extended clumps along the mini-spiral. We also detect MIR counterparts of the radio tail components of the IRS 7 source. They show a clear kinematical deviation with respect to the star. They likely represent Kelvin–Helmholtz instabilities formed downstream in the shocked stellar wind. We also analyze the shape and orientation of the extended late-type IRS 3 star that is consistent with the Atacama Large Millimeter/submillimeter Array submillimeter detection of the source. Its puffed-up envelope with a radius of ∼2 × 106
R
⊙ could be the result of the red-giant collision with a nuclear jet, which was followed by tidal prolongation along the orbit.
A rare synchronous presentation of primary malignant melanoma in cervix and vagina
Authors: Pai Usha K. N. , Pillai Sreekumar , Arunkumar N. R. 
Published: April 2022

ABSTRACT
Malignant melanoma, primarily a cutaneous malignancy, can also involve mucosal surfaces and constitutes 2% to 7% of all gynecological malignancies. Primary melanoma of the uterine cervix is an uncommon tumor and has poor prognosis. In the female genital tract, the synchronous occurrence of primary malignant melanoma in the cervix and vagina is rare. We report a case of a 48-year-old female patient who presented with a blackish vaginal mass and associated growth in the cervix. Biopsy from the vaginal mass was reported as malignant melanoma. Following this, she underwent radical surgery and adjuvant radiotherapy. After 12 months, the patient is doing well.
O Negacionismo: uma Crise Social da Relação com a “Verdade” na Sociedade Contemporânea
Authors: Charlot Bernard , Capua da Silva Charlot Veleida Anahi 
Published: April 2022

Este artigo tem como objetivo esclarecer o conceito de negacionismo e o contexto socioepistemológico em que esse fenômeno está se produzindo. A noção de pós-verdade não passa de uma primeira abordagem do negacionismo e a análise epistemológica não é suficiente para entender o fenômeno. O negacionismo pode até procurar argumentos na epistemologia contemporânea da ciência. O artigo propõe analisar o negacionismo a partir da teoria da relação com o saber de Charlot. Com base nessa teoria, o artigo interpreta o negacionismo como uma crise social da relação com a verdade. Essa crise decorre de um acúmulo de problemas ecológicos e sanitários ligados à ciência e de uma politização das questões de saúde. Algumas vezes, essa crise induz tentativas de reapropriação cidadã dessas questões, contra os "especialistas". Outras vezes, ela leva ao negacionismo, que se enraiza numa convicção que não se importa com a verdade da fala, mas com uma identidade de grupo. Desconfiando da Ciência, recusando o debate, construindo inimigos míticos, o negacionismo desvaloriza a educação e o pensamento crítico e, logo, é fundamentalmente antidemocrático. Ele é a forma epistemológica da barbárie contemporânea.
Diamonds from low-grade kimberlite
Authors: Zinchuk Nikolay , Bardukhinov Leonid 
Published: April 2022

Based on exploration and sampling work on the Siberian
platform (SP) the uneven diamond content of
various diatremes was established. During the exploration
apart from the pipes with high or medium content
of a useful component also the diatremes with low to
very low diamond content were discovered. To obtain
representative data the diatremes of two kimberlite fields
of the Central Siberian (CS) and six kimberlite fields of
the Lena-Anabar (LA) diamondiferous sub-provinces
(DSP) were studied. A comprehensive study of diamonds
from low-grade pipes of the Alakit-Markhinsky and
Daldynskoye kimberlite fields of CSDSP was carried out.
16 kimberlite bodies from six kimberlite fields from the
LADSP were studied. Geology and mineral-petrographic
composition of kimberlites, crystal-morphological and
physical properties of diamonds from certain prospective
areas were investigated. In addition to classifying
diamonds into specific varieties according to Yu. L. Orlov
(1984), for many crystals, we examined impurity
centers, the ratio of the concentration of optically active
defects, spectra of absorption of diamonds IR and UV
for the visible regions. For many grains we determined
the isotopic composition of carbon; carried out analyses
using the electron paramagnetic resonance (EPR) method;
measured the photoconductivity upon excitation
with visible light; analyzed photoluminescence spectra;
studied the internal structure and composition of the mineral
inclusions. The obtained results were compared
with similar materials for the known primary (and sometimes
alluvial) deposits of the region. Based on the
study of the typomorphic features of diamonds from lowgrade
kimberlite pipes from selected fields of the SP we
conclude that they are characterized by a high content
of typical rounded minerals of the Ural (Brazilian) type
with shagreen and plastic deformation bands. This indicates
a significant dissolution of the mineral in the
kimberlite of such diatremes, which distinguishes them
from similar bodies with high diamond content and makes
it possible to predict the grade already at the initial
stages of exploration work. Increased content of small
semitransparent smoky-brown rounded diamonds with
shagreen and plastic deformation bands for crystals from
veins was noted, which is also typical for low-grade pipes.

Convolutional neural networks for image-based sediment detection applied to a large terrestrial and airborne dataset
Authors: Chen Xingyu , Hassan Marwan A. , Fu Xudong 
Published: April 2022

Abstract. Image-based grain sizing has been used to measure grain size more
efficiently compared with traditional methods (e.g., sieving and Wolman pebble
count). However, current methods to automatically detect individual grains
are largely based on detecting grain interstices from image intensity which
not only require a significant level of expertise for parameter tuning but
also underperform when they are applied to suboptimal environments (e.g.,
dense organic debris, various sediment lithology). We proposed a model
(GrainID) based on convolutional neural networks to measure grain size in a
diverse range of fluvial environments. A dataset of more than 125 000
grains from flume and field measurements were compiled to develop GrainID.
Tests were performed to compare the predictive ability of GrainID with
sieving, manual labeling, Wolman pebble counts (Wolman, 1954) and
BASEGRAIN (Detert and Weitbrecht, 2012). When compared with the sieving
results for a sandy-gravel bed, GrainID yielded high predictive accuracy
(comparable to the performance of manual labeling) and outperformed
BASEGRAIN and Wolman pebble counts (especially for small grains). For the
entire evaluation dataset, GrainID once again showed fewer predictive errors
and significantly lower variation in results in comparison with BASEGRAIN and
Wolman pebble counts and maintained this advantage even in uncalibrated
rivers with drone images. Moreover, the existence of vegetation and noise
have little influence on the performance of GrainID. Analysis indicated that
GrainID performed optimally when the image resolution is higher than 1.8 mm pixel−1, the image tile size is 512×512 pixels and the grain area
truncation values (the area of smallest detectable grains) were equal to 18–25 pixels.
Effective uncertainty visualization for aftershock forecast maps
Authors: Schneider Max , McDowell Michelle , Guttorp Peter , Steel E. Ashley , Fleischhut Nadine 
Published: April 2022

Abstract. Earthquake models can produce aftershock forecasts, which have recently been released to lay audiences. While visualization literature suggests that displaying forecast uncertainty can improve how forecast maps are used, research on uncertainty visualization is missing from earthquake science. We designed a pre-registered online experiment to test the effectiveness of three visualization techniques for displaying aftershock forecast maps and their uncertainty. These maps showed the forecasted number of aftershocks at each location for a week following a hypothetical mainshock, along with the uncertainty around each location's forecast. Three different uncertainty visualizations were produced: (1) forecast and uncertainty maps adjacent to one another; (2) the forecast map depicted in a color scheme, with the uncertainty shown by the transparency of the color; and (3) two maps that showed the lower and upper bounds of the forecast distribution at each location. We compared the three uncertainty visualizations using tasks that were specifically designed to address broadly applicable and user-generated communication goals. We compared task responses between participants using uncertainty visualizations and using the forecast map shown without its uncertainty (the current practice). Participants completed two map-reading tasks that targeted several dimensions of the readability of uncertainty visualizations. Participants then performed a Comparative Judgment task, which demonstrated whether a visualization was successful in reaching two key communication goals: indicating where many aftershocks and no aftershocks are likely (sure bets) and where the forecast is low but the uncertainty is high enough to imply potential risk (surprises). All visualizations performed equally well in the goal of communicating sure bet situations. But the visualization with lower and upper bounds was substantially better than the other designs at communicating surprises. These results have implications for the visual communication of forecast uncertainty both within and beyond earthquake science.
STATISTICAL EDUCATION FOR PHD STUDENTS IN UK MEDICAL SCHOOLS
Authors: WILLIAMSON PAULA R. , LANCASTER GILLIAN A. 
Published: April 2022

Little is known about the provision of statistics teaching for PhD students in UK medical schools. A recent survey found that statistics courses were available to PhD students in 13 of 21 schools responding. The provision across these 13 schools was variable in terms of contact hours and content. At a meeting of 27 medical statistics teachers, consensus was reached that such teaching should be undertaken by a subject specialist, however there was no consensus as to the best mode of delivery. We describe the rationale for, content of, and student feedback from our newly developed course programme which emphasises aspects of both design and analysis of research projects.

Evidence on Irish Company Managers’ Views About Dividend Policy
Authors: McCluskey Thomas , Burton Bruce , Power David 
Published: April 2022

This study investigates the views of Irish corporate managers regarding dividend policy. It seeks to explain (i) how firms determine dividend levels, (ii) perceptions of the relationship between dividend policy and firm value, and (iii) the role of earnings, risk preferences and tax clienteles in determining payout ratios. Data were obtained from a mail survey sent to the top 1,000 Irish companies. The empirical results highlight several clear patterns in the general attitudes of Irish firms to dividend policy as well as a number of areas where specific differences in perceptions exist across the respondent groups.
Metropolitan’s “Winter Dreams” and The Great Gatsby
Authors: Mangum Bryant 
Published: April 2022

Abstract
While many scholars have pointed to the close relationship of “Winter Dreams,” which Fitzgerald referred to as “A sort of 1st draft of the Gatsby idea,” to The Great Gatsby, most have used the revised 1926 version collected in All the Sad Young Men to support their comparisons of story to novel. The text of “Winter Dreams” in Fitzgerald’s third short story collection, however, is a dramatically revised version of the original story that appeared in the December 1922 issue of Metropolitan Magazine. A reading of the Metropolitan version of “Winter Dreams,” when done with the holograph manuscript of The Great Gatsby, the galley proofs, the revised galley proofs of the novel, and the novel itself in mind, suggests that at many stages of the composition of Gatsby, Fitzgerald had the Metropolitan text of “Winter Dreams” close at hand as he composed Gatsby . He borrowed near-exact phrasings from the story and placed them in the novel, and he appropriated key dramatic elements in the relationship between Dexter Green and Judy Jones in the story and integrated them with subtle changes that can be tracked through the various stages of composition of Gatsby into the relationship between Jay Gatsby and Daisy Fay Buchanan. In the end, the Metropolitan version of “Winter Dreams” reveals itself to be the text that most clearly bears out Fitzgerald’s description of the story as “A sort of 1st draft of the Gatsby idea.” Examining The Great Gatsby after a close reading of the Metropolitan version of “Winter Dreams” shows story and novel to be much more closely related than has previously been considered.
Effect of nicotine alkaloid extract of Nicotiana tabacum L. on the gene expression of heat shock proteins and apoptosis encoding genes in MCF-7 and Hela cancer cell lines
Authors: Khalaf Amenah Khudhair , Mohammed Ibrahim Hadi 
Published: April 2022

Nicotiana tabacum L contains a many active compounds such as Nicotine, which have anti-cancer activities. Apoptosis is a regulated mechanism, and the main feature of it is activating of caspase-9. Also, heat shock proteins overexpression leads to the development of cancer. The current study is aimed to investigate the effect of Nicotine extract at IC50 (450, 75) µg\ml on the expression of the (Heat shock protein70, Hypoxia-inducing factor, P53, B-cell lymphoma-2-Associated-X-protein, and Caspase-9) in cancer cell lines, and observation the morphological changes. The quantitative Real-Time Polymerase Chain Reaction is used to analysis of gene expression by using A Kapa syber green stain, and the Acridine Orange\ Propidium iodide stain also used to observe the morphological changes. The results of this study showed that the treatment of cells with Nicotine extract at IC50 inhibits the expression of heat shock proteins encoding genes and increased the expression of apoptosis encoding gene. Also, many morphological changes was observed in apoptotic cells. The study concluded that the extract of Nicotine alkaloid of Nicotiana tabacum L. can induce the apoptosis and inhibit the expression of heat shock proteins in cancer cells making this plant is a promising option for cancer treatment, but need more research.

Abstrak
Penelitian ini bertujuan untu mengkaji pengaruh teman sebaya terhadap motivasi belajar seseorang khususnya dalam mata pelajaran Agama Hindu. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan analisis data secara teoretis mengacu pada Teori Belajar Sosial. Data-data yang tersaji dalam tulisan ini merupakan hasil studi pustaka baik dari media cetak maupun media elektronik mengenai teori belajar sosial, serta hasil pengamatan langsung peneliti. Berdasarkan hasil kajian ditemukan bahwa kelompok teman sebaya dapat menjadi sebuah role model bagi personal kelompok yang kemudian terimbas atas pengaruh dominan yang diakui dalam kelompok. Dalam konteks belajar, keberadaan kelompok teman sebaya ini secara positif dapat meningkatkan motivasi belajar siswa, termasuk motivasi belajar Agama Hindu. Hal ini dikaitkan dengan proses pembelajaran yang dilalui pada pembelajaran sosial Bandura, yaitu fase perhatian (attentional phase), fase retensi (retentional phase), fase produksi (production phase), dan fase motivasi (motivational phase). Pada fase perhatian, personal kelompok akan melakukan pengamatan (observasi) serta penilaian atas personal yang lain, kemudian pada fase retensi personal akan mengingat kembali bagaimana pola perilaku dominan dalam kelompok teman sebaya. Selanjutnya akan muncul fase produksi sebagai bentuk perilaku yang muncul atas interaksi yang telah dilakukan, hingga muncul fase terakhir, yaitu fase motivasi. Pada fase terakhir inilah menjadi titik tolak dari sebuah interaksi, yang mana masing-masing personal saling memotivasi satu sama lain. Melalui hasil penelitian ini, diharapkan dapat digunakan sebagai ide atau pandangan baru dalam menyikapi masalah motivasi belajar Agama Hindu dengan memperhatikan lingkungan pertemanannya.
Some agroclimatic aspects of sorghum and millet production in India
Authors: MASKE SJ , SAMUI RP 
Published: April 2022

Studies of sorghum and millet spread and yield indices in Indian districts juxtaposed with water balance revealed that sorghum and millet are extensively cultivated in semi-arid region having an average positive water balance of 1-3 months or receiving an average annual rainfall of 400 to 1000 mm,
Drought in the growing period is the major constraint to sorghum production in semi-arid region of India, but low temperature in the rabi season (October-March) is also a problem especially in the northern region. A comparison between sorghum and millet production in northern India and the January mean temperature shows that sorghum and millet crops do not do well in areas where the January mean temperature is below 15°C.
Diagnostic study of a Bay of Bengal monsoon depression, July 1979
Authors: MANDAL GS , SAHA SK , GUPTA SC 
Published: April 2022

Upper winds from the depression field especially in the formation stage are the major constraints, for studying their detailed structure at this stage.
Monsoon Experiment (MONEX) in 1979 has provided, adequate upper air data from a depression field which formed in the north Bay of Bengal on 7 July 1979. Based on these observations, certain features like thermal structure, distribution of vorticities, divergence, radial and tangential wind, vertical wind shear inflow and out flow and vertical velocities associated with the depression have been computed and the results presented in this paper.
"Genesis Parameter" designed by Gray (1978) for the development of the storm based on the product of coriolis parameter, vorticity parameter, vertical wind shear parameter, ocean energy parameter, stability parameter and relative humidity parameter have been computed. In the present case, the above genesis parameter is computed to be 46 x 10-8 car K sec-1 cm-3 which is more than the average non-developing depression (26 x 10-8 calo K sec-l cm-3) and less than the developing depression (55 x 10-8 calo K sec-l cm-3) in the Atlantic.
Strengthening of extra-tropical westerlies and formation of new wind maxima at 200 hPa over Indian region during winter and pre-monsoon seasons
Authors: SINGH RANJIT 
Published: April 2022

There is a general strengthening of the extra-tropical westerlies in response to the organisation of strong convection in tropics. In the four case studies presented the formation of westerly wind maxima over a station at 200 hPa has been explained with the help of conservation of angular momentum when an air stream emerging from the top of the cloud acquires an additional westerly momentum during its northward motion. The air stream was identified by the continuity of outflowing cirrus cloud over the station. In such cases the westerlies extend deep into equatorial region and a double jet stream appears south of the main sub-tropical jet stream over Indian region. Further, westerlies are likely to be stronger during nights than during day time under the same forcing.
The study conducted has shown that westerlies over the Indian region west of 80 deg. E strengthen in response to the intensification of convection in the equatorial trough over Arabian Sea.
