Proliferation of Levanderina fissa and Polykrikos hartmannii (dinophyceae: Gymnodiniales) in Bahía de La Paz, Gulf of California, México.
Authors: Gárate -Lizárraga I. 
Published: January 2021

On 19–20 August 2014, a moderate proliferation of dinoflagellates was detected in the southwestern part of Bahía de La Paz. The phytoplankton community within this red tide was composed of 60 microalgae taxa and was characterized by the presence of unarmored dinoflagellates such as Levanderina fissa and Polykrikos hartmannii. The proliferation occurred during low tide after a period of windy and rainy days. Densities of L. fissa varied from 163 to 265 × 103 cells L–1 and for P. hartmannii varied from 16 to 33 × 103 cells L–1. Low densities were estimated on September and October samplings. Both species showed a great variation both in size and form. As part of the phytoplankton species composition during this proliferation, two taxa of dinoflagellates are new records for the Pacific coast of Mexico (Ankistrodinium semilunatum and Sclerodinium calyptroglyphe), one in the Gulf of California (Pronoctiluca acuta), and one in the Bahía de La Paz (Prorocentrumrobustum). Cyanobacteria were an important group observed during this proliferation. The symbiotic association between a cyanobacterium Synechococcus sp., the stramenopile protist Solenicola setigera, and the diatom Leptocylindrus mediterraneus was observed for the first time in this bay.

Les images manquantes
Authors: Pierre-Bouthier Marie 
Published: January 2021

La problématique de « l’image manquante », développée par le cinéaste franco-cambodgien Rithy Panh, est opérante dans la plupart des dictatures. Cet article re-parcourt l’histoire du documentaire marocain à l’aune de cet enjeu, en prenant pour point d’entrée la représentation de la répression des années 1980. Après une relecture entre les lignes, entre les images, à revers, d’un documentaire « un peu trop » de propagande, Une journée au Maroc, Mohamed Laâlioui, 1982, on décrit comment, contre ce genre d’occultation criante de la réalité par le cinéma officiel marocain, les médias français ont cherché obsessionnellement les « images manquantes » de la répression politique au Maroc, en particulier le magazine Résistances de Bernard Langlois. Aujourd’hui enfin, la nécessité de pallier le manque d’images de cette période de l’histoire du Maroc constitue un véritable moteur de recherche et de création pour des cinéastes contemporains comme Ali Essafi, Leila Kilani ou Hicham Lasri.

Software Requirements Specification Document must be complete, unambiguous and correct because an incorrect Software Requirements Specification Document can lead to failure in software development. Software Requirements Specification document must contain non-redundant sentences. Meyer's Seven Sins describes several errors in Software Requirements Specification Document, one of which is redundancy which is a variant of noise. Redundancy is the repetition of the same information, but using different terms or phrases, thus giving the impression that new information is available. This study analyzes the performance of the framework and tools for detecting redundancy in sentence pairs in the software requirements specification document using the WordNet-based semantic similarity method. This study tries to develop the framework and tools that have been proposed in previous studies, namely by detecting redundancy in sentence pairs without fact extraction. The proposed approach and evaluation process uses Kappa values ??to determine whether the performance of the framework and assistive tools can be used to detect redundancy in sentence pairs properly.
The method using literature study, data collection, problem analysis, making a framework, making auxiliary tools, and testing. The test uses the Kappa value with two scenarios, from the results of testing the framework and assistive tools can be used to detect redundancy in the Software Requirements Specification Document with a Kappa value of 0.777 with the interpretation of the kappa value is a substantial agreement at a threshold of 0.73

El carcinoma vesical músculo invasivo de estirpe urotelial presenta una alta probabilidad de producir metástasis, siendo los órganos más frecuentes el pulmón, hueso o hígado. Las metástasis de carcinoma urotelial de vejiga en el testículo son excepcionales. Los tumores primarios que metastatizan en testiculo son la leucemia, el prostático, el pulmonar, el melanoma o los de origen digestivo. Presentamos un caso de metástasis asincrónica de carcinoma urotelial en el testículo derecho. Las metástasis testiculares deben reconocerse como un posible diagnóstico diferencial de masa gonadal en el caso de existir antecedentes de un tumor vesical musculo invasivo (TVMI).

Descripción: Él caso es un paciente de 18 años de edad que acudió por hematuria y retención aguda de orina. Fue diagnosticado por cistoscopia y resección transuretral de próstata (rtup); rabdomiosarcoma de próstata.
Relevancia: Muy pocos casos reportados en el país y en la literatura mundial, que hacen difícil la sospecha diagnóstica, y una vez que se tiene formulan un reto terapéutico y multidisciplinario.
Implicaciones clínicas: Hematuria y crecimiento prostático obstructivo, en pacientes menores de la cuarta década de la vida son los rasgos que deben llamar el interés para la sospecha de este tipo de neoplasia.
Conclusiones: Los sarcomas de próstata son tumores poco frecuentes, lo cual dificulta el conocimiento de su historia natural. La progresión local y a distancia es muy rápida, con una supervivencia media de 2 años, a pesar del manejo terapéutico multimodal. El principal factor de supervivencia es una resección completa del tumor, un estadio local poco avanzado y grado tumoral. Es necesario buscar nuevos protocolos quimioterápicos que permitan prolongar la supervivencia de estos pacientes como se ha demostrado en otro tipo de sarcomas de extremidades.

Authors: Badmus N. I. , Olanrewaju Faweya , Adeniran A. T. 
Published: January 2021

Objective: This paper examines and upgrades a two-parameter double exponential distribution to a four-parameter beta double exponential model by compounding the baseline distribution and beta link function to fits and analyse deaths-cases data set of the recent outbreak of the global pandemic coronavirus disease (COVID-19) for both Africa and Non-Africa countries. The new proposed model, although complex in its mathematical structure, yet flexible to implement and its robustness to accommodate non-normal data is an extra advantage to statistical theory and other fields.
Methodology: The statistical properties: the density function, cumulative distribution function, survival function, hazard function, moments, moments generating function, skewness and kurtosis of the developed model were presented. Maximum likelihood method is used for parameters estimation procedure. The new model is validated and compared with some frontier similar extant parametric family of beta distributions using graphs, Kolmogorov Smirnov (KS) Statistic, Log-likelihood and model criteria statistics like Akaike Information Criteria (AIC), Bayesian Information Criteria (BIC) and Consistent Akaike Information Criteria (CAIC) as tools for comparison.
Results: The graphs, KS, LogL and model criteria statistics values showed that the proposed model fits the COVID-19 pandemic data better than other competing models since the model has lower values as stated: The values from non-African countries KS = 0.1208, LogL = 278.4168, AIC = 560.8336, BIC = 576.1147 and CAIC = 577.1147. Also, from African countries are: KS = 0.0759, LogL = 144.0245, AIC = 292.0490, BIC = 303.9302 and CAIC = 304.9302.
Conclusion: The proposed model showed its applicability and flexibility over other models considered in this work. Therefore, this implies that the new model can be used for modeling other infectious disease data and real data in many fields.
Chandrayaan-2: A Memorable Mission Conducted by ISRO
Authors: Sarkar Buddhadev , Mani Pabitra Kumar 
Published: January 2021

Aims: The Chandrayaan-2 aims to wave the Indian flag on the dark side (South Pole) of the Moon that had never been rendered by any country before. The mission had conducted to gather more scientific information about the Moon. There were three main components of the Chandrayann-2 spacecraft- an orbiter, a lander, and a rover, means to collect data for the availability of water in the South Pole of the Moon.
Place and Duration of Study: The rover (Pragyan) was designed to operate for one Lunar day that is equivalent to 14 Earth days, whereas the orbiter is assumed to orbit the Moon for seven years instead of the previously planned for just one year.
Overview: The Chandrayaan-2 spacecraft launched by India's heavy-lift rocket Geosynchronous Satellite Launch Vehicle-Mark III (GSLV MKIII) from the Satish Dhawan Space Center launch pad located on Sriharikota island of Andhra Prades. Unlike, Chandrayaan-1, this lunar mission aimed to perform a soft-landing on the South Pole of the Lunar surface and do scientific experiments with the help of the rover (Pragyan).
Reason: The Chandrayaan-1, the first lunar mission of ISRO that detected water molecules on the Moon. The Chandrayaan-2 was a follow-on mission of Chandrayaan-1 to explore the presence of water molecules on the South Pole of the Moon.
Conclusion: Although the orbiter fulfilled all of the command, unfortunately, the lander (Lander) lost its communication at the last moment to touch the Moon’s surface softly. Despite that, India again showed its potential in space missions. Chandrayaan- 2 was the most low budget lunar mission ever conducted by any space organization. The developing or even underdeveloped countries may come forward in their space program as ISRO is showing a convenient way in space missions.

AbstractNanocomposite materials are assuming increasingly important roles across contemporary materials science. Analytical characterizations and visualizations of nanoscale interphases/interfaces are critical to development of novel multiphase nanostructures and nanoscale systems. While conventional vibrational spectroscopies are indispensable physicochemical characterization tools, standard techniques such as Fourier‐transform and quantum cascade laser infrared (IR) microspectroscopies are intrinsically limited in spatial resolution by the wavelength‐dependent diffraction limit of IR light (≈5–12 µm). Optical‐photothermal infrared (O‐PTIR) with simultaneous hyperspectral Raman microspectroscopy (O‐PTIR+R) is a novel all‐optical technique that circumvents such diffraction limits, yielding position‐specific IR spectra with sub‐micrometer wavelength‐independent resolution across the mid‐IR. This work implements single‐frequency O‐PTIR with concomitant hyperspectral Raman microspectroscopy to resolve interfacial regions in a poly(octadecyl acrylate)‐grafted‐multiwall carbon nanotube (PODA‐g‐MWCNT) nanocomposite for wearable temperature sensors and highlights how the O‐PTIR+R technique can be used for analytical characterization and visualization of other nanocomposite systems below resolution limitations of conventional IR spectroscopies.
