Published: November 2021

Sand mining in the village of Sp Padang is carried out in an open pit mining model through several processes, for example the washing process which is carried out to separate sand from other components.When the sludge in the form of mud and fine sand enters the river, this part causes the quality of river water around the sand mining location to decline. The purpose of this research was to determine the condition of water quality due to sand mining in the river Sp.Padang.The type of data collected is primary data. The research was conducted at 3 stations on the river Sp.Padang.The physico-chemical parameters of river water are used, namely: turbidity, temperature, pH, TSS, DO, BOD, COD, water discharge and current velocity. The data obtained from the laboratory were then analyzed, then comparisons were made with the Storet method.Sampling for water quality replaces the surrounding area with direct measurements and measurements made in the laboratory.The use of the Storet method refers to PP No. 82 of 2001. The principle of Storet is to integrate river water quality data with river water standards and then adjust it according to its use, by classifying water quality into four classes. The results of the data analysis of the quality of river water in Sp.Padang as a result of the sand mining activities are categorized as good class B (lightly polluted) with a score of -6. Sand mining activity affects the water quality of the Sirah River in Padang Island, OKI Regency.Key words : OKI, sand miners, storet method, water quality

ABSTRAKAncaman radikalisme dan terorisme hingga saat ini masih berkembang di Indonesia. Kelompok yang rentan dari pergerakan gerakan radikal ini adalah pelajar sekolah menengah atas, civitas akademika kampus, serta masyarakat umum secara terbatas. Hal ini tentu saja menjadi ancaman serius bagi negara, karena dapat mengancam keamanannasional dan masyarakatnya. Oleh karena itu, perlu dilalukan pencegahan dini terhadap radikalisme yang dapat berujung pada aksi terorisme. Tindakan pencegahan ini dapat dilakukan melalui berbagai upaya seperti meningkatkanketahanan masyarakat. Dalam menjawab persoalan di atas, penelitian ini menggunakan metode kualitatif dengan pendekatan analitis deskriptif, sehingga penelitian ini mendeskripsikan mengenai fenomena gerakan radikal dan aksi terorisme di Indonesua dan menganalisis upaya pencegahan dini yang dapat dilakukan oleh Pemerintah. Hasil penelitian menunjukkan bahwa terdapat dua pola penyebaran radikalisme di Indonesia, yaitu melalui Lembaga Swadaya Masyarakat (LSM) tertentu dan pembentukan kelompok-kelompok kajian. mengingat rentanya masyarakat khususnya kaum pelajar akan ancaman radikalisme ini, maka upaya pencegahan dapat dilakukan dengan memberikan pemahaman bela negara melalui mata pelajaran Pendidikan dan Kewarganegaraan. Dalam pelajaran ini, siswa / mahasiswa diberikan pemahaman mengenai nilai-nilai dasar bela negara, sehingga ancaman dari paham-paham radikalisme terhadap masyarakat dapat dicegah secara dini.Kata kunci: Radikalisme, Terorisme, Bela Negara, Perguruan Tinggi, dan Keamanan Nasional ABSTRACTAbstract:The threat of radicalism and terrorism is still on developing phase in Indonesia. Groups that are vulnerable to this radical movement are high school students, the campus academic community, and society in a limited manner. This is a serious threat to the state because it can threaten national security and the society. Therefore, it is necessary to do early prevention against radicalism which can lead to acts of terrorism. This preventive action can be done through various efforts such as increasing community resilience. In answering the problems above, this study uses a qualitative method with a descriptive-analytical approach. Furthermore, this research will describe the phenomenon of radical movements and acts of terrorism in Indonesia and analyzes early prevention efforts that can be carried out by the Government. The results showed that there were two patterns of the spread of radicalism in Indonesia, first, through non-governmental organizations (NGOs) and the formation of study groups. Furthermore, preventive action could be carried out by providing an understanding of state defense through Civic Education. In this lesson, the students are given an understanding of the basic values of state defense, so radicalism threat can be prevented early.Keywords: Radicalism, Terrorism, State Defense, Higher Education, and National Security

Authors: Yunfeng Bai  , Zelong He  , Jiyuan Bai  , Suihu Dang
Published: November 2021

The single-mode fiber provided by YOFC inc is employed for spiral processing by commercial welding machine. It can clearly see the periods structure under the light, but there is no obvious deformation of the fiber core, cladding and surface morphology under a microscope. There is an obvious resonant peak near 1560 nm, half peak width is about 25 nm, the depth of the resonant peak closed to –26 dB, when the period is about 411 μm. It agrees with theoretical calculation results according to the long-period fiber grating coupled-mode theory. The resonance wavelength is caused by coupling between the fundamental mode and the LP14 mode. The responsivities of the helically twisted long-period fiber gratings (H-LPFG) for the temperature is measured, the resonance wavelength is linear with temperature, the slope is 86 pm/℃. Because it is easy to inscribe by commercial welding machine, and has a strong resonance peak, it has potential applications as the temperature sensor.
Influence of dispersion slope on soliton spectral tunneling in photonic crystal fiber
Authors: Yunxia Yang  , Hua Yang  , Xiongfeng Tong  , Saili Zhao  , Shuyuan Chen
Published: November 2021

We report a numerical investigation of how the dispersion slope affects the soliton spectral tunneling (SST) in a photonic crystal fiber with three zero dispersion wavelengths. It is discovered that a larger dispersion slope makes group-velocity mismatch between the initial soliton and the transferred wave thereby suppressing the SST effect, while a proper decrease of the dispersion slope enhances the SST effect to widen a supercontinuum range. Besides, we find a soliton-like leaking dispersion wave, which can sustain information and energy for a short time within a particular spectral range.
Teachers’ Innovation and Learners’ Academic Achievement in Public Primary Schools in Marakwet East Sub- County, Kenya
Authors: Kilimo Simon Riatum , Cheboi Stephen Tomno
Published: November 2021

Innovative and creative instruction is key towards helping learners in schools understand concepts being taught and perform well in their studies. One of the expectations from teacher performance appraisal and development (TPAD) is that teachers should make sure that they make their lessons to be innovative and creative in order for learners to develop knowledge and acquire required competencies. This paper looks at how teachers are using creativity and innovation in their teaching and its influence on learners’ academic achievement in public primary schools. The study was conducted in public primary schools in Marakwet East Sub County involving all teachers (581) and headteachers (83) employed by the Teachers Service Commission (TSC). A descriptive survey design was utilised for this investigation. A sample size representing 20.0% of respondents 17 head teachers and 117 teachers who were selected via a simple random sampling method. The instruments used to collect data consisted of questionnaires for teachers and interview schedules for headteachers. Data collected was analysed using quantitative and qualitative methods. The study found out that teachers’ use of creativity and innovation methods influenced learner academic achievement. However, the research found that the usage of ICT resources was low and this explains how very few teachers were accessing and utilising online resources for their learners. This means that despite teachers having the capacity to effectively make sure their classrooms experiences involve innovation and creativity is hampered by a lack of adequate infrastructure facilities like computers, laptops, internet, and electricity. In conclusion, teachers’ use of creativity and innovation approaches in teaching was found to influence the academic performance of learners in public primary schools in Marakwet East Sub County. The paper recommends that government needs to ensure that all schools are connected to the national grid of fibre optic cable and electricity
Women and Church Ministry in Africa: Removing the Impasse Towards a Fruitful Theological Conversation.
Authors: Mwania Patrick
Published: November 2021

Women in Africa, both in the traditional setup and in modern society form the cornerstone of the Church and society. They have spearheaded change in traditional and modern society and heralded the Gospel message on the African soil. Based on the formidable roles women played and the influential areas of authority they occupied in the social, economic, political, and religious dimensions of African traditional societies, such as priestesses, diviners, medicine women etc., I attempt to understand the role women play and the place they occupy in the Church and in society today taking the Catholic Church as a case study. The aim of this paper is to seek to understand the roles women play in society, as well as discerning how the roles could be promoted and improved for the betterment of the Church and society. For the discussion to achieve its objective, the following areas will be addressed: explore the place and the significance that traditional African society accorded to women;  investigate the nature of women’s involvement in the life of the community as well as the precise roles that traditional society assigned to women; discover the place of women in Christianity and some of the roles the Catholic Church assigns to women members as documented; understand some of the challenges women face as members of the Church and  the roles they play in enhancing the Gospel; and finally attempt to provide some recommendations in response to some of the challenges identified.
TREE IMAGE OF SIBERIA: LARCH
Authors:   Altai State Pedagogical University, Bogumil T. A.
Published: November 2021

The dendroimage image of Siberia is considered in the context of geopoetics and ethnodendrology. For the first time the proposed analysis systematizes the motives associated with the image of larch, one of the main trees in the region. The research materials are scientific works on ethnography and folklore studies, Russian and Russian-language fiction about Siberia written in the XIX-XX centuries. The name of the tree reflects its dual status: coniferous and deciduous simultaneously. The “gender” of the larch is also indeterminate: male / female. The larch has an «intermediate» position in the system of the most important dendroimages of the Siberian text: between cedar and birch. It can be associated with universal tree mythologemes (World Tree, Tree of Life and Death, family tree, etc.), but it most clearly embodies the basic concept of Siberia as a space of violence, hard labor, exile, concentration camps.
ON THE PARADOXICAL NATURE OF LAUGHTER IN THE LITERATURE OF THE XXTH CENTURY
Authors:   Samara National Research University named after Academician S. P. Korolev, Golubkov S. A.
Published: November 2021

The article deals with the attraction of the art of the 20th century to the paradox as a tool for understanding the absurdity of life. Paradox and laughter share their inherent structural ambiguity, pulsating ambivalence. Paradox and laughter are often a platform for the conflict of different logics - ordinary logic and “paralogy” (alogism). Consideration of the typology of objects of ridicule helps to reveal the paradoxical nature of laughter. At the same time, attention is drawn to two types of object: an integral system (institution, professional team, power institutions) and an individual person (in particular, an adventurous hero). It is interesting to study the paradoxical in the very fabric of a comic work. In particular, pleonasm is described as a component of the funny technique. It denotes a paradoxical contradiction between the necessary and the redundant in the description. Paradoxically, the two-dimensional texts associated with the laugh attitude, which are built on the model of the anti-genre, have a conflict-like nature: false panegyrics, anti-idylls, dystopias.

Authors: Gretzschel Isabelle , Aßmus Daniela , Fritzlar Torsten
Published: November 2021

In der Auseinandersetzung mit mathematischen Problemstellungen werden Schülerinnen und Schüler immer wieder mit unterschiedlichen und auch für sie neuen Anforderungen konfrontiert. Für deren erfolgreiche und effiziente Bearbeitungen, abseits oft langwieriger willkürlich probierender Vorgehensweisen, sind Anpassungen an die jeweils vorliegenden Bedingungen erforderlich. Diese Fähigkeit wird nicht nur im alltäglichen Sprachgebrauch als Flexibilität bezeichnet. Vor diesem Hintergrund interessieren wir uns für den Umgang mit geringfügig variierten mathematischen Problemstellungen, bei deren Bearbeitungen zuvor verwendete Vorgehensweisen unter Anpassung an die veränderten Bedingungen erneut genutzt werden können. Im Rahmen einer Interviewstudie wurde dafür eine Problemserie zu unterschiedlichen Anforderungen zum Rückwärtsarbeiten entwickelt. Aus den Variationen der Probleme resultierte die Notwendigkeit, nicht probierend angelegte Vorgehensweisen zu verändern. Der Beitrag soll einen ersten Einblick in den Umgang von Schülerinnen und Schülern der sechsten Klassenstufe mit dieser Problemserie bieten. Die Bearbeitungen wurden mittels qualitativer Inhaltsanalyse kategoriebasiert ausgewertet und mit dem Verständnis von Flexibilität als Handlungsmerkmal in einem neu entwickelten Synthesemodell zusammengeführt, welches flexibles Handeln beim Bearbeiten mathematischer Probleme veranschaulichen soll.

Novel Coronavirus leads all the educational institutions to think of e-learning platforms to continue the education. E-learning tools are playing a crucial role during this pandemic, it aims to help instructors, and universities facilitate student learning during periods of university closure. The study attempts to examine the influence of e-learning factors on student’s learning focusing on teacher, content, technology, student. A structured questionnaire was used to collect data from 249 bachelor students through a web-based survey at Arab Open University and was analyzed with various statistical tools which can be used to test the relationship between the variables. However, it was revealed that teachers, content, technology, and students play a significant role in the e-learning system. Through a stepwise multiple regression model, it was revealed that e-learning plays a significant role in knowledge enhancement and student learning. Further noted that gender, mode of study, program of study has a significant effect on e-learning factors. Students were exposed to the e-learning system and feel more confident and comfortable while working on it. It is therefore recommended that an e-learning environment can increase the learning potential of the students. e-learning is a good solution during this pandemic situation. Students should be motivated and satisfied with the instructor's support and course policies tend to perceive their learning outcomes higher. Both teachers and students have had to re-adapt the way they prepare, access, and engage with e-learning environment. Even though there are few challenges in adopting e-learning technologies, the educational institutions are supporting in all possible ways and provide an uninterpreted education to all the student community

THE IMPACT OF REMITTANCES OF TAJIK MIGRANTS FROM THE USA TO THE ECONOMY OF TAJIKISTAN
Authors: Rakhmonov A. Kh.
Published: November 2021

Таджикистан является одной из стран-лидеров в мире по доле денежных переводов мигрантов в структуре валового внутреннего продукта. Например, в начале мирового кризиса, в 2008 г., 49% ВВП Таджикистана приходилось на денежные переводы мигрантов. Показано, что денежные переводы таджикских мигрантов играют существенную роль в социально-экономическом развитии страны в целом, а также отдельных домохозяйств, позволяя реализовывать основные потребности в покупке еды, товаров длительного пользования, вложений в строительство и ремонт жилья, инвестировать в развитие образования для детей. В отличие от других стран, большая часть денежных переводов в Таджикистане поступает через легальный банковский канал, что также оказывает положительное влияние на экономику Республики. Легализации денежных переводов способствовала отмене 30%-ого налога от денежных переводов, а также приравнивание их к банковским операциям. В работе показана роль денежных переводов таджикских трудовых эмигрантов из США.

In our presentation we would like to demonstrate how the staff of the Hungarian Prison Service has protected and continues to protect against an invisible ‘enemy’”, a human epidemic caused by the COVID–19 virus. We have been fighting this battle under the continuous guidance of the Operational Body established at the Hungarian Prison Service Headquarters (hereinafter: the Body). We describe what immediate, preventive measures were put in place by the Body to prevent coronavirus infection from entering the prisons and other penitentiary facilities. We present how the spreading of the infection was prevented after the appearance of the infection in the prisons with the start of the second wave, and furthermore what tools and methods did we use to protect ourselves during the period of the third wave. How the life of the Prison Service changed overnight, what additional burdens did the control of the human epidemic meant for the staff, how the epidemic affected the daily life of the prisoners, their admission, their employment, the inmates’ contact with their relatives and contact persons, and their transportation and escort to trials.
Operation and Role of the Operative Body of the Hungarian Prison Service Headquarters in the Fight Against Covid-19 Epidemic
Authors: Schmehl János
Published: November 2021

During the coronavirus pandemic the Hungarian Prison Service had to introduce measures that were unknown for the service previously and which had a significant impact on the daily duty of the staff. To adapt measures taken by the government for the prison service, the pandemic risks occurring during the special activities had to be modelled. The Operational Body built-up and operated in the Hungarian Prison Service Headquarters took several measures that ensured the framework of rules needed for successful protection. The virus could not enter the Hungarian prisons during the first wave and later on the statistics show more favorable infection and mortality rates among the inmates than in civil life. The current study presents the strategy of defense and the method of central management, as well as provides insight into the background of the decisions made.
CREATIVITY IN COMPUTER SCIENCE
Authors: Giza Piotr
Published: November 2021

The aim of this paper is to briefly explore creative thinking in computer science, and compare it to natural sciences, mathematics or engineering. It is also meant as polemics with some theses of the pioneer work under the same title by Daniel Saunders and Paul Thagard because I point to important motivations in computer science the authors do not mention, and give examples of the origins of problems they explicitly deny. Computer science is a very specific field for it relates the abstract, theoretical discipline – mathematics, on the one hand, and engineering, often concerned with very practical tasks of building computers, on the other. It is like engineering in that it is concerned with solving practical problems or implementing solutions, often with strongly financial reasons, e.g. increasing a company’s income. It is like mathematics in that is deals with abstract symbols, logical relations, algorithms, computability problems, etc. Saunders and Thagard analyse rich experimental material from historical and contemporary work in computer science and argue that, as opposed to natural sciences, computer science is not concerned with describing and explaining natural phenomena. Now, I argue that there is a field of research in artificial intelligence (which, in turn, is a branch of computer science), called machine discovery, where explanation of natural phenomena, finding experimental laws and explanatory models is the primary goal. This goal is achieved by constructing computer systems whose job is to simulate various processes involved in scientific discovery done by human researchers, and help them in making new discoveries. On the other hand, motivations that give rise to ingenious projects in computer science can be very strange and include curiosity, fun or attempts to be famous out of boring, stable life of a successful programmer in a big corporation. A good example is the phenomenon of open-source software, especially the development of the Linux operating system and its applications when, from economical point of view, Microsoft absolutely dominated the software market of personal computers.

Published: November 2021

The aim of the paper is to provide an overview of the sensitivity in terms of the preference for using the integrated reporting quality (IRQ) based on the reporting companies’ field of activity. The study focusses on designing a sensitivity analysis relying on the most relevant financial and nonfinancial indicators as required by the stakeholders. They were adjusted by the key factors for the IRQ such as the social, natural, human and intellectual capital. The study has been designed based on the upgrade and in compliance with the connectivity principle as required by the IIRC. The data was collected from the IR examples Database between 2015–2017. The results suggest that based on sensitivity function value, those sectors of activity such as transportation and infrastructure, services and trade have a higher sensitivity preference for the IR due to the quantification of the stakeholders’ interest in terms of performance positive trend indexes. Making use of regressive techniques, the authors undertook an econometrical model for the evaluation of the IRQ that may become very useful for those companies that intend to set in place a sustainable business as it provides them the opportunity of measuring the IRQ.
Reconciling the 16.35-day Period of FRB 20180916B with Jet Precession
Authors: Chen Hao-Yan , Gu Wei-Min , Sun Mouyuan , Liu Tong , Yi Tuan
Published: November 2021

A repeating fast radio burst (FRB), FRB 20180916B (hereafter FRB 180916), was reported to have a 16.35-day period. This period might be related to a precession period. In this paper, we investigate two precession models to explain the periodic activity of FRB 180916. In both models, the radio emission of FRB 180916 is produced by a precessing jet. For the first disk-driven jet precession model, an extremely low viscous parameter (i.e., the dimensionless viscosity parameter α ≲ 10−8) is required to explain the precession of FRB 180916, which implies its implausibility. For the second tidal-force-driven jet precession model, we consider that a compact binary consists of a neutron star/black hole and a white dwarf; the white dwarf fills its Roche lobe, and mass transfer occurs. Due to the misalignment between the disk and orbital plane, the tidal force of the white dwarf can drive jet precession. We show that the relevant precession periods are several days to hundreds of days, depending on the specific accretion rates and component masses. The duration of FRB 180916 generation in the binary with extremely high accretion rate will be several thousand years.
Eclipsing Binaries in the Open Cluster Ruprecht 147. IV: The Active Triple System EPIC 219511354
Authors: Torres Guillermo , Vanderburg Andrew , Curtis Jason L. , Kraus Adam L. , Gaidos Eric
Published: November 2021

We report follow-up spectroscopic observations of the 1.62 day, K-type, detached, active, near-circular, double-lined eclipsing binary EPIC 219511354 in the open cluster Ruprecht 147, identified previously on the basis of photometric observations from the Kepler/K2 mission. This is the fourth eclipsing system analyzed in this cluster. A combined analysis of the light curve and radial velocities yields accurate masses of M
Aa = 0.912 ± 0.013 M
☉ and M
Ab = 0.822 ± 0.010 M
☉ for the primary (star Aa) and secondary (Ab), along with radii of R
Aa = 0.920 ±0.016 R
☉ and R
Ab = 0.851 ± 0.016 R
☉, and effective temperatures of 5035 ± 150 and 4690 ± 130 K, respectively. Comparison with current models of stellar evolution for the known age and metallicity of the cluster reveals that both radii are larger (by 10%–14%) and both temperatures cooler (by ∼6%) than theoretically predicted, as is often seen in M dwarfs. This is likely caused by the significant stellar activity in the system, manifested here by 6% peak-to-peak out-of-eclipse variability, a filled-in Hα line, and its detection as an X-ray source. We also find EPIC 219511354 to be a hierarchical triple system, with a low-mass tertiary in an eccentric 220 day orbit.
Time Evolution of a System of Particles Obeying Coulomb’s Law and the High-speed Rollover of Suprathermal Tails in the Solar Wind
Authors: Randol Brent M.
Published: November 2021

In this article, we show through a series of rigorous mathematical steps, starting with Liouville’s equation and solving it for the case of two protons using the method of characteristics, that a velocity distribution function, f(u), is formed that exhibits a power law, f ∝ u

γ
, where γ is −9/2, and an exponential-type rollover at large speeds, providing a potential explanation for the observations of suprathermal ions in the solar wind. The solution is valid for all times and all background conditions, though the power law does at some point merge with the core of the distribution. When it does so, a final distribution is found that agrees with overall energy conservation. Analytical approximations to the solution are discussed, along with explanations for the various phases that the solution undergoes.

We present the Virgo Environment Traced in CO (VERTICO) survey, a new effort to map 12CO (2–1), 13CO (2–1), and C18O (2–1) in 51 Virgo Cluster galaxies with the Atacama Compact Array, part of the Atacama Large Millimeter/submillimeter Array. The primary motivation of VERTICO is to understand the physical mechanisms that perturb molecular gas disks, and therefore star formation and galaxy evolution, in dense environments. This first paper contains an overview of VERTICO's design and sample selection, 12CO (2–1) observations, and data reduction procedures. We characterize global 12CO (2–1) fluxes and molecular gas masses for the 49 detected VERTICO galaxies, provide upper limits for the two nondetections, and produce resolved 12CO (2–1) data products (median resolution = 8″ ≈ 640 pc). Azimuthally averaged 12CO (2–1) radial intensity profiles are presented along with derived molecular gas radii. We demonstrate the scientific power of VERTICO by comparing the molecular gas size–mass scaling relation for our galaxies with a control sample of field galaxies, highlighting the strong effect that radius definition has on this correlation. We discuss the drivers of the form and scatter in the size–mass relation and highlight areas for future work. VERTICO is an ideal resource for studying the fate of molecular gas in cluster galaxies and the physics of environment-driven processes that perturb the star formation cycle. Upon public release, the survey will provide a homogeneous legacy data set for studying galaxy evolution in our closest cluster.

Published: November 2021

X-ray quasi-periodic eruptions (QPEs) are a recently discovered phenomenon associated with supermassive black holes at the centers of galaxies. They are high-amplitude soft X-ray flares that recur on timescales of hours, but what causes these flares remains uncertain. In the two years since their original discovery, four known QPE-hosting galaxies have been found, with varying properties and levels of activity. We have conducted a blind algorithm-assisted search of the XMM-Newton Source Catalog and found a fifth QPE candidate, XMMSL1 J024916.6-041244. This is a star-forming galaxy hosting a relatively low-mass nuclear black hole, and has previously been identified as a tidal disruption event candidate. An XMM-Newton pointed observation of the source in 2006 exhibited nearly two QPE-like flares in soft X-rays, and unlike in other QPE sources, there are hints of corresponding dips in the UV light curves. Afterwards, a series of Swift observations observed the rapid dimming of the source; thereafter, in 2021 August, we triggered a second XMM-Newton observation, which revealed that the source is detected, but the QPEs are no longer present. Here we report on (I) the strategy we used to systematically search through XMM-Newton archival data; (II) the properties of J0249 and its QPE flares; and (III) the relative behaviors and properties of the QPE sample to date, now five members large.

We observed Jupiter’s thermal emission with SOFIA/FORCAST in 2018 August and 2019 July. Both broad-band images (8–37 μm) and spectra (17–37 μm) were obtained. We used the shape of the Jovian spectra to determine the latitudinal distribution of temperatures and para-H2 in the upper troposphere, and compared this to similar data obtained in Fletcher et al. (2017). The two data sets were taken approximately half a Jovian year apart, the first (2014) during northern summer (L

s
= 158°) and the second (2019) during southern summer (L

s
= 304°). During both epochs the high northern latitudes are cooler than the south. Para-H2 is observed in sub-equilibrium at the equator and in super-equilibrium near the poles during all epochs. The largest difference between the two epochs is the detection of high-para-H2 content at high southern latitudes in 2019, in contrast to the earlier (2014) observations. This implies that the high-latitude para-H2 appears to vary over multi-year timescales. In addition to aiding in the calibration of and providing context to the Jovian spectra, the images were used to determine spectra of the four Galilean satellites. Over the 8–35 μm wavelength range the brightness temperatures of all four satellites drop with increasing wavelength. Although this is expected as longer wavelengths probe the satellites’ deeper, cooler layers, our data quantify the brightness temperature gradient with wavelength.
The Estimate of Interferon-inducible Protein-10 and Interferon-γ in Hemodialysis Patients with Chronic HCV
Authors: Altobje Mahmood Abdujabar , Al-Rrassam Zeyad Thanoon
Published: November 2021

BACKGROUND: Due to the rise in the number of deaths, the hepatitis C virus remains a public health issue worldwide. During the recovery period, cytokines are known as indicators of chronic liver infection.

AIM: In this study, immunological parameters were measured and calculated in chronic hemodialysis patients after more than 6 months of drug administration.

METHODS: We have picked 60 patients with hemodialysis who are anti-HCV positive. ELISA and the calculation of alkaline phosphatase (ALP) were used to evaluate IP-10 and IFN-γ.

RESULTS: A substantial association between variables and infected cases was found. No worth was considered for genders or age categories.

CONCLUSIONS: The serum IP-10 level can be a warning primarily for patients who have taken a variety of prescriptions intermittently. In both the RPT and RST cohorts, IFN-γ serum levels are usually elevated. Serum level ALP is not a particular chronic HCV predictor.
The flora of south-eastern Mato Grosso State (Brazil): a review of herbarium collections

The diversity and richness of the Brazilian flora are documented in herbarium collections. When areas are deforested, but not documented, we lose both flora and the opportunity to know which species occupied those areas. The south-eastern mesoregion of Mato Grosso State, comprising 22 municipalities, has undergone the loss of native vegetation cover, accelerated by the substantial expansion of agribusiness. For an in-depth look at the consequences and the current state of the flora in that mesoregion, we consulted both speciesLink and JABOT databases. More specifically, we carried out a comprehensive study of herbarium collections by municipality and compiled data including scientific name, collection date, collection locality, collector name and observations made during collection. We obtained 5,861 records of angiosperms, ferns and lycophytes of 160 families, 770 genera and 1,792 species. The specimens are deposited in 80 herbaria of which the Herbarium of Universidade Federal de Mato Grosso (UFMT) hosts the largest collection. Rondonópolis was the most sampled municipality, whereas 50% of the municipalities were poorly sampled and one showed no collection records at all. Amongst the species occurring only in Mato Grosso, eleven were collected only in that mesoregion and twenty species were under some degree of threat. Our study recommends increasing collection and identification efforts to enable effective conservation actions and improve richness estimates for the State of Mato Grosso and the Cerrado, in general, before more of the flora is lost to deforestation.

Published: November 2021

Metformin and glibenclamide may have beneficial effects on the levels of trace elements in diabetic patients. The aim of the current study was to assess the effects of metformin and glibenclamide on the concentrations of copper (Cu), zinc (Zn) and magnesium (Mg) in patients with type 2 diabetes mellitus. The metformin-treated patients showed significantly lower serum Cu levels compared with the untreated and glibenclamide groups. In addition, treatment with metformin was associated with a significant increase in serum concentrations of Zn compared to the newly diagnosed patients, whereas it did not show a noticeable alteration in the serum level of Mg. In contrast, the glibenclamide treated group revealed significantly higher Zn and Mg levels compared with the newly diagnosed group, while the serum level of Cu was not significantly modified. In conclusion, treatment with metformin led to a reduction in serum Cu and an increase in serum Zn concentrations, whereas glibenclamide treatment displayed enhancement in serum Zn and Mg levels.
CIRCLE Software for Management of Epithelial Ingrowth After SMILE
Authors: Kankariya Vardhaman P. , Gogri Pratik Y. , Dube Ankita B. , Mohiuddin Syed Maaz , Madia Tanvi , Vaddavalli Pravin K.
Published: November 2021

PURPOSE:

To report a novel therapeutic use of CIRCLE software (Carl Zeiss Meditec) to manage visually significant epithelial ingrowth following small incision lenticule extraction surgery (SMILE).

METHODS:

Case series.

RESULTS:

In this case series, the authors describe three eyes with progressive and visually significant epithelial ingrowth following an uneventful SMILE procedure. The management of epithelial ingrowth following SMILE is challenging, given the small access incision to the interface and the risk of incomplete removal. All cases were successfully managed by converting the SMILE cap into a flap using the CIRCLE software, which provided the necessary access to the original SMILE interface. Once the flap was lifted, the epithelial in-growth was completely debrided from the underlying stroma and undersurface of the flap, followed by a thorough interface wash. Postoperative recovery was uneventful, with no recurrence noted in any of the eyes.

CONCLUSIONS:

Use of CIRCLE software provides a novel and unique approach to successfully treating vision-threatening epithelial ingrowth after SMILE.
