Published: September 2021

O protocolo de armadilhamento fotográfico TEAM para o monitoramento de vertebrados terrestres de médio e grande porte permite estimativas de parâmetros da biodiversidade que informam os gestores de áreas protegidas sobre os impactos de ameaças ou de ações de manejo da biodiversidade. Neste trabalho, apresentamos resultados de 4 anos do monitoramento TEAM na Reserva Biológica do Gurupi com objetivo de avaliar sua efetividade na conservação de vertebrados terrestres de médio e grande porte da Amazônia maranhense. Foram avaliadas tendências temporais na riqueza e composição da comunidade, nas taxas de ocupação das espécies monitoradas e no Wildlife Picture Index, índice sensível às mudanças na biodiversidade. Foram registradas 36 espécies de vertebrados de médio e grande porte, representando 72% das aves e 96% dos mamíferos com ocorrência na Amazônia maranhense. As populações monitoradas, inclusive de espécies endêmicas e ameaçadas de extinção, permaneceram estáveis ao longo de 4 anos de monitoramento. A taxa de ocupação da maioria das espécies aumentou no período de monitoramento, refletindo no aumento do Wildlife Picture Index. Possivelmente essas tendências têm relação com o grande incêndio florestal que assolou a Reserva Biológica do Gurupi em 2015, indicando a recuperação da biota e a resiliência frente a eventos extremos. Os resultados obtidos demonstram que a Reserva Biológica do Gurupi tem sido efetiva e tem papel de destaque na conservação de vertebrados terrestres de médio e grande porte da Amazônia maranhense.

A Comparison in Work-Up Between the First and Second Covid 19 Infection in the Same Patients in the ED Tawam Hospital, UAE
Authors: Al-Shamri Hussein Kzar Basi
Published: September 2021

Aim of study: To identify the significance of routine laboratory investigations conducted in patients infected with COVID-19 for the second time as compared to being infected with COVID-19 for the first time in the UAE.

Methods: 345 patients between the ages of 16 and 65 years who were infected with COVID-19 were included in the study. Patient’s charts were reviewed and all laboratory tests and imaging conducted were reviewed. Furthermore, patients were divided into two groups: one as a first time COVID-19 infection group and the other as a second time COVID-19 infection group.

Results: Fifteen laboratory tests have been conducted. Of these tests, 44.4% (4 tests) (procalcitonin, phosphate, magnesium, amylase, and lipase) that were abnormally elevated in patients in the first infection group were found to be significantly reduced in patients with a second COVID-19 infection. Also, two imaging modalities done which included Chest–X ray and CT thorax without contrast were abnormal in all the patients in the second infection group.

Conclusion and recommendations: We recommend not using the following labs in patients with COVID-19 infection for the second time: procalcitonin, magnesium, lipase, amylase, phosphate. However, we do recommend performing Chest X-ray and CT thorax without contrast in assessing severity of disease in patients with COVID-19 infection for the second time.

Authors: Сысоев О.Е. , Сысоев Е.О. , Добрышкин А.Ю.
Published: September 2021

В статье рассмотрена проблема предотвращения разрушения опор нефтегазовых морских платформ при передислокации. Цилиндрические конструкции опор нефтегазовых платформ очень чувствительны к динамическим воздействиям внешних сил, которые вызывают колебания конструкций и явление резонанса, особенно при передислокации. Цилиндрические опоры платформ также несут дополнительные массы (оборудование, антиледовый пояс и т.п.), которые оказывают значительное влияние на динамику работы оболочек. В статье уточнена математическая модель колебаний оболочек, несущих дополнительную массу, на основе теории Рейснера. Проведены экспериментальные исследования на уменьшенных моделях оболочек, проверки уточнённой математической модели, показано сравнение экспериментальных и теоретических исследований. Основное отличие скорректированной математической модели заключается в присутствии нового параметра, учитывающего влияния наличия малой дополнительной массы. Уточненнаяматематическая модель позволит более точно рассчитывать частоты колебаний конструкции в режиме online, и предотвращать возможные разрушения цилиндрических опор конструкций нефтегазовых платформ при передислокации.

The article deals with the problem of preventing the destruction of the supports of oil and gas offshore platforms during relocation. Cylindrical structures of oil and gas platform supports are very sensitive to dynamic influences of external forces, which cause vibrations of structures and the phenomenon of resonance, especially during relocation. Cylindrical platform supports also carry attached masses (equipment, anti-ice belt, etc.), which have a significant impact on the dynamics of the shells operation. The article refines the mathematical model of vibrations of shells carrying the added mass on the basis of Reisner's theory. Experimental studies are carried out on reduced models of shells, verification of the refined mathematical model, a comparison of experimental and theoretical studies is shown. The main difference of the corrected mathematical model is the presence of a new parameter that takes into account the influence of the presence of a small added mass. The refined mathematical model will make it possible to more accurately calculate the vibration frequencies of the structure online, and prevent possible destruction of the cylindrical supports of the structures of oil and gas platforms during relocation.
Finite-time and spectral-finite methods of optimal filtering of discrete signals
Authors: Иванов Ю.П.
Published: September 2021

На основе содержания теоремы ортогонального проецирования излагаются методы оптимальных, линейных рекуррентных оценок, в общем случае, не марковских, сигналов, на фоне произвольных помех. Предлагаемые алгоритмы оптимальной обработки дискретных сигналов являются альтернативными методу фильтрации Калмана, не отличающимися заметно от них по точности обработки и являющимися более универсальными и простыми при их реализации. Универсальность исследуемых методов определяется применимостью их к широкому классу моделей сигналов, не требующих марковского свойства оцениваемого сигнала и изменения структуры алгоритма оценки в зависимости от моделей помех измерения в виде случайного коррелированного процесса или белого шума. Более простые структуры алгоритмов рассматриваемых методов по отношению к фильтрации Калмана объясняются отсутствием необходимости представления модели в пространстве состояний и требования решать нелинейное уравнение Риккати для реализации алгоритма. Спектрально-финитный алгоритм оптимальной оценки сигнала осуществляет сжатие информации в спектральном аспекте на основе использования метода нахождения собственных чисел и векторов и позволяет осуществить понижение размерности векторов результатов измерений вплоть до скалярных величин без заметной потери точности оценки. В качестве исходной информации необходимо знание корреляционной функции и математического ожидания оцениваемого дискретного сигнала и дисперсии и математического ожидания дискретной помехи.

Based on the content of the orthogonal projection theorem, methods of optimal, linear recurrent estimates of, in general, non-Markov signals, against the background of arbitrary interference, are presented. The proposed algorithms for optimal processing of discrete signals are alternative to the Kalman filtering method, which do not differ significantly from them in terms of processing accuracy and are more universal and simple to implement. The universality of the studied methods is determined by their applicability to a wide class of signal models that do not require the Markov property of the estimated signal and changes in the structure of the estimation algorithm depending on the measurement interference models in the form of a random correlated process or white noise. The simpler structures of the algorithms of the methods under consideration in relation to Kalman filtering are explained by the absence of the need to represent the model in the state space and the requirement to solve the nonlinear Riccati equation for the implementation of the algorithm.
Features of hydraulic calculation of marine vacuum fish pumping units
Authors: Ахмедова Н.Р. , Наумов В.А.
Published: September 2021

Цель статьи – модифицировать ранее разработанный метод гидравлического расчета вакуумной перекачивающей системы для течения в рыбонасосной установке, работающей на промысловом судне. Динамика откачивания и закачивания воздуха в буферную емкость не изменилась. Анализ экспериментальных данных показал, что гидравлические потери по длине трубопровода прямо пропорциональны величине массовой доли рыбы. В судовых условиях потери напора в местных гидравлических сопротивлениях могут иметь тот же порядок, что и потери по длине. В отличие от традиционных судовых систем течение жидкости в вакуумных рыбонасосных установках (ВРУ) является нестационарным из-за увеличения давления в буферной емкости, как на этапе всасывания, так и на этапе вытеснения. Что приводит к необходимости совместного решения уравнения Бернулли для нестационарных течений совместно с дифференциальными уравнениями для давления и объема жидкости в буферной емкости. Увеличение длины трубопровода или перепада высот приводит к снижению скорости движения водорыбной смеси и увеличению давления в буферной емкости. Как следствие, возрастает продолжительность цикла работы ВРУ и падает производительность.

The purpose of the article is to modify a previously developed method of hydraulic calculation of a vacuum pumping system for a flow in a fish pump unit operating on a fishing vessel. The dynamics of pumping out and pumping air into the buffer tank did not change. Analysis of experimental data showed that hydraulic losses along the length of the pipeline are directly proportional to the value of the mass fraction of fish. In shipboard conditions, head losses in local hydraulic resistances can be of the same order as length losses. In contrast to traditional ship systems, the fluid flow in vacuum fish pumping units (VFP) is unsteady due to an increase in pressure in the buffer tank, both at the stage of suction and at the stage of displacement. This leads to the need of jointly solve the Bernoulli equation for unsteady flows together with differential equations for the pressure and volume of fluid in the buffer tank. An increase in the length of the pipeline or the height difference leads to a decrease in the speed of movement of the water-fish mixture and an increase in pressure in the buffer tank. As a result, the duration of the VFP operation cycle increases and the productivity decreases.

Published: September 2021

Building Information Modelling (BIM) has been touted as a new outstanding technology and governments who have noticed this is getting involved. This study investigated the current level of the Kenyan Government’s involvement and how this has influenced adoption amongst building contractors. This study also compares global trends in the context to Kenya. This study identified roles like initiation and regulation that governments could undertake to encourage adoption. A random sampling of registered contractors with active construction sites within Nairobi County was used to identify respondents. Using a one-sample t-test with a universal mean of 2 representing weak government involvement, with t (61) = 2.39, α > 0.05, M = 2.05 and S = 1.53, the Kenyan government’s involvement in BIM and its performance on the roles was weak. There was no relationship between the government roles and BIM except for BIM Initiation which had a weak positive relationship. This study makes recommendations like the creation of a legal BIM mandate and the establishment of a BIM implementation body This is the first in-depth study in Kenya that critically looks at the government’s role on issues relating to BIM amongst Building contractors and gives precedence for subsequent comparative studies locally or regionally.
A Concise Insight on Pulsatile Drug Delivery System: An Outlook towards its Development
Authors: Bagade Om M , Sutar Snehal S , Doke Priyanka E
Published: September 2021

In pharmaceutical science, the pulsatile drug delivery system gains more attraction because of their number of benefits over the other dosage forms. In these systems, the drug is released at right time at the right site of action, and in the right amount, it is the most beneficial and important characteristic of the PDDS system due to that the patient compliance is increased, and the drug release is after a well-defined lag time.  Moreover, this system is designed according to the circadian rhythm of the body. Because the disease has a predictable cyclic rhythm, such as Arthritis, diabetes mellitus, asthma, peptic ulcer, hypertension, cardiovascular disease the PDDS is more effective than other dosage forms.This system is a more time-specific and site-specific drug delivery system. In this system the drug is released as a pulse. The mechanism of PDDS is first diffusion then erosion and then osmosis. For the drug having a high first-pass effect and having a high risk of toxicity and side effects, these systems can be very useful. And to reduce dosing frequency and improve patient compliance this system is very helpful. There are various methods present like, single-unit systems and multiple-unit systems – which included capsular system, pulsatile delivery by osmosis, pulsatile delivery by erosion of membrane, delivery by rupture of membrane, etc.

Published: September 2021

Nanoparticles such as Fe, FeO, CuO, Zn, ZnO, and Se play an important role in aquaculture. These compounds are essential minerals to increase fish growth and supplemen-tation in feeds because practical feedstuffs contain low levels of these microminerals. Dietary supplementation of nanoparticles produces greater survival, growth, antioxidant levels and immunity of aquatic organisms including fishes. The present study deals with the impact of different quantity of green synthesized iron oxide nanoparticles on growth, enzymatic, biochemical changes, and hematology of Zebrafish Danio rerio. Anisomeles malabarica leaf extract was used for the synthesis of iron oxide nano-particles and characterized by XRD, SEM, EDAX, and FT-IR. Six feeds were prepared with different quantity of synthesized iron oxide nanoparticles (F1 - Control, F2 -10 mg, F3 – 20mg, F4 – 30mg and F5 – 50mg) and feed ingredients are fish meal, groundnut oilcake, wheat flour, and tapioca flour. Growth, digestive enzymes (protease, amylase, and lipase), biochemical constituents (total protein, carbohydrate and lipid) and hematological parameters were estimated after 30 days. ‘t’ test and One-way ANOVA was used for the analysis. The feed consumption, feed conversion efficiency, weight gain, percentage growth, relative growth rate, assimilation, metabolism, gross and net growth efficiency were higher in F5 containing 40mg of green synthesized iron oxide nanoparticles (1.98 ± 0.29, 0.19 ± 0.02, 0.85 ± 0.32, 2.88 ± 0.74, 2.21 ± 0.70, 1.61 ± 0.11, 44.31 ± 10.58 and 42.11 ± 9.46). 40mg of iron oxide nanoparticles supplemented feed enhanced the digestive enzymes and biochemical constituents of Zebrafish. The results conclude that 40 mg iron oxide nanoparticles supplemented feed enhanced the growth, digestive enzymes, biochemical constituents, and hematology of Zebrafish.

Published: September 2021

Heat exchangers are almost used in every industry. Among them, shell and tube heat exchangers are covering around 32% of the total heat exchanger. Numerical simulation of the Computational models is playing an important role for the prototypes including the Heat Exchanger Models for the improvement in modeling. In this study, the CFD analysis of parallel and counter flow shell and tube heat exchanger was performed. Following project, looked into the several aspects and these are the temperature, velocity, and pressure drop and turbulence kinetic energy along with the heat exchanger length. Hot water was placed in tube side and cold water was placed in shell side of the heat exchanger. Shell side cold temperature was increasing along the heat exchanger length. On the other side, tube side hot water temperature was decreasing along the tube length. This effect was more significance in counter flow rather than the parallel flow. Velocity was more fluctuating in the shell side due to presence of the baffles. Also following the same reason, pressure drop was higher in the shell side cold water rather than the tube side hot water. To measure the turbulence effect, turbulence kinetic energy was determined. Turbulence was decreasing first part of the shell and tube heat exchanger. But, it was increasing along through the rest part heat exchanger. All these observations and the outcomes are evaluated and then further analyzed

Published: September 2021

In this research, nanocomposites consisting of a mixture of linear low-density polyethylene polymer (LLDPE) and zinc oxide nanoparticles (ZnO-NPs) were prepared. The films of the composite material were formed with five weight ratios (0.25, 0.5, 1, 2.5, and 5wt%) in addition to pure LLDPE, intended to investigate the role of nanomaterials in improving the performance of some properties of LLDPE polymer such as increasing the shelf life of food products and protecting the consumer from pathogenic germs in food packaging applications. The efficacy was evaluated against pathogenic bacteria, Escherichia coli and Staphylococcus aureus, through the standard "ISO 22196". The test results confirm that the nanocomposite films containing 0.5wt% or more of nano-zinc oxide have bacteriostatic activity. This activity increases with the increase of ZnO-NPs in the LLDPE polymeric phase, and the highest antibacterial effect was in the nanocomposite films of 5wt%. It was found that gram-positive bacteria were more sensitive to ZnO-NPs than gram-negative bacteria and that these nanocomposite films can provide a safe way to preserve food without the need for food processing.

Molla Sadrâ’nın Tasavvuf Yorumu ve Dönemin Sözde Mutasavvıflarına Yönelttiği Eleştiriler
Authors: MEÇİN Mahmut
Published: September 2021

İslâm düşüncesinin bir yenilenme ve muhasebe sürecini yaşadığı klasik sonrası dönem, İslâm felsefesinin dönüşüm geçirerek asıl mecrasını bulduğuna tanıklık eden bir dönemdir. Bu dönemde Antik-Helenistik düşüncenin etkisinin azalmasıyla beraber felsefenin, kelâm ve tasavvuf gibi İslâm düşünce gelenekleriyle etkileşimi artmış ve aralarında önemli sentezler tesis edilmeye çalışılmıştır. İslâm düşüncesinin bütüncül bakış açısını yakalamak için ortaya konulan bu çabaların en mücessem örneklerinden biri Meşşâî, İşrâkî, Ekberî ve kelam okulları arasında hikmetü’l-müteâliye terkibiyle bir uzlaşı tesis etmeye çalışan Molla Sadrâ’nın (1570-1641) çabasıdır. Molla Sadrâ’nın tesis etmeye çalıştığı bu uzlaşıda tasavvufa yaklaşımı ve dönemin mutasavvıflarına yönelttiği eleştiriler bu makalenin konusunu oluşturmaktadır. Makalenin bahse konu ettiği problem, şu sorulara cevap bulmaya çalışmaktadır: Molla Sadrâ’nın temel referansları arasında tasavvuf nerede durmaktadır? Molla Sadrâ’nın tasavvuf anlayışının arka planında hangi isim ve öğretiler bulunmaktadır? Molla Sadrâ kendi dönemindeki mutasavvıflara ne gibi eleştiriler yöneltmiştir? Bir sûfî-filozof (teosof) olarak görülmesine rağmen Molla Sadrâ’nın kendi dönemindeki mutasavvıflara yönelttiği eleştirilerde amacı nedir ve bu eleştiriler nasıl anlaşılmalıdır? Tasavvuf, Sadrâ’nın senteze dayalı felsefesinin karakterini belirleyen en önemli kaynaklardan biridir. Sadrâ’nın tasavvuf anlayışında başta Ekberî geleneğin varlık anlayışı olmak üzere klasik İslam filozoflarının Yeni Eflatuncu düşünceleri ve Sühreverdî’nin İşrâkî öğretilerinin etkisi belirgin bir şekilde kendini göstermektedir. Bilhassa İbnü’l-Arabî’nin vahdetü’l-vücûd anlayışının, Sadrâ’nın tasavvuf anlayışının arka planında en önemli etkiye sahip olduğu söylenebilir. Bununla birlikte Sadrâ yaşadığı dönemde tasavvufu bütünüyle zahirî ritüellerden ibaret gören nazarî bilgiden yoksun mutasavvıflara eleştiriler yönelterek tasavvufu özünden uzaklaştırmalarına karşı çıkar. Sadrâ, artan cehalet, aklî ve nazarî araştırmalardan yoksunluk, süslü söz ve şathiyelerle insanlar nezdinde makam elde etme arzusu ve şeriatın zahirine göre hüküm verme gibi tutum ve davranışlara dikkat çeker. O, bu tür eğilimleri birer cehalet putu olarak değerlendirerek insanı hakikatten uzaklaştıran ve derhal bertaraf edilmesi gereken birer engel olarak kabul eder. Sadrâ’nın eleştirilerinde tasavvufî öğretileri ve geleneğini topyekûn bir eleştiriye tabi tutmaksızın asıl maksadının tasavvufu nazarî boyutundan ve irfanî derinliğinden uzaklaştıran anlayışın tehlikesine karşı uyarmak olduğunu ve belirli şahıs veya kurumları değil, doğru bulmadığı tutum ve inançları hedef aldığını özellikle belirtmesi onun eleştiri üslûbunu dikkate değer kılmaktadır. Makalenin amacı İslâm düşünce ekolleri arasında sağlamaya çalıştığı sentezde Molla Sadrâ’nın tasavvuf yorumunu anlamaya çalışmak ve arif olarak görmediği sözde mutasavvıflara karşı geliştirdiği eleştirilere dikkat çekerek İslâm medeniyetinin eleştiri kültürünü anlamak ve onu bugüne taşımaktır.
Lâmiyyetü’l-ʿAcem Şerh-Hâşiye Geleneğinde Kurucu Bir Eser: Safedî’nin Ġays̱ü’l-Edeb’i
Authors: CENGİZ Mehdi
Published: September 2021

Tuğrâî’nin (öl. 515/1121) Lâmiyyetü’l-ʿacem adlı kasidesi, kullanılan belâgat sanatları, veciz üslubu ve içerdiği hikmetli sözlerle Arap edebiyatında önemli bir yer tutar. Bundan dolayı kaside üzerine onlarca şerh, hâşiye, tahmîs ve taştîr çalışması kaleme alınmıştır. Memlükler döneminde kâtiplik ve beytülmâl vekilliği gibi önemli görevler üstlenen Safedî (öl. 764/1363) de Tuğrâî’nin kasidesini şerh eden edebiyatçılar arasında yer alır. Kasideyi iştikak, gramer, beyân, meânî, bedîʿ gibi dil ve belâgat ilimleri açısından inceleyip şerh eden Safedî, bu eserinde kimyadan biyolojiye, tarihten felsefeye pek çok disiplinle alakalı ayrıntılı bilgi verir. Yer yer kendi şiirlerini de zikreden Safedî’nin çalışması, aynı zamanda bir şiir antolojisi niteliğindedir. Bu makalede, Safedî’nin Ġays̱ü’l-edebilleẕî inseceme fî şerḥi Lâmiyyeti’l-ʿacem adlı eserinin muhtevası ve şerh yöntemi hakkında bilgi verilip bu yapıtın Lâmiyyetü’l-ʿacem şerh-hâşiye geleneğinde temsil ettiği kurucu rol gösterilecektir. Bu bağlamda Safedî’nin şerhinin, hâşiye ve ihtisâr gibi çalışmaların yapılması ile diğer Lâmiyyeti’l-ʿacem şerhlerinden ayrılıp müstakil bir gelenek oluşturduğu dikkat çekmektedir. Nitekim kaleme alınan onlarca ihtisâr ve haşiye çalışmaları Safedî’nin eserinin Lâmiyyetü’l-ʿacem literatüründe kurucu bir metin olduğunu göstermektedir. Eser üzerine yapılan ihtisar çalışmaları Safedî’nin üslubunun kapalı olup izaha ihtiyaç duyması ile değil, Tuğrâî’nin Lâmiyye’si ile doğrudan ilişkili olmayan istidradî bilgilere yer vermesi ile alakalıdır. Söz gelimi Safedî Lâmiyyeti’l-ʿacem ile alakası olmayan satranç, çeşitli fabl örnekleri, güneşin tanımı, ayın ışığını güneşten nasıl aldığı, güneş ve ay tutulması gibi pek çok konuya yer verir. Safedî bu yazım şeklini bilinçsiz olarak kullanmayıp aksine Câhiz’ın (öl. 255/869) Kitâbü’l-Ḥayavân’ında takip ettiği bu metodu benimsediğini eserinin mukaddimesinde söylemiştir. Ayrıca Safedî’nin zikrettiği bazı hikayeler sonraki âlimler tarafından müstehcen kabul edilmiş dolayısıyla eserin ihtisar edilmesi yeğlenmiştir. Bu çerçevede Demîrî’nin (öl. 808/1405) el-Maḳṣadü’l-etem fî Şerḥi Lâmiyyeti’l-ʿacem adlı çalışması diğer ihtisarlar arasında öne çıkmıştır. Bunun yanında İbnü’d-Demâmînî’nin (öl. 827/1424) kaleme aldığı Nüzûlü’l-Ġays̱illleẕî inseceme ʿalâ şerḥi Lâmiyyeti’l-ʿacem adlı tenkit çalışması da kayda değerdir. İbnü’d-Demâmînî, Safedî’nin eserini ihtisar etmek yerine tenkit etmeyi tercih etmiş ve yer yer Safedî’yi sirkatle itham etmiştir. İbnü’d-Demâmînî’nin haksız eleştirilerinin olduğunu ifade eden İbn Akbers ise Taḥkîmu’l-ʿuḳûl bi ufûli’l-Bedri fî’n-Nuzûl adlı bir çalışma hazırlayarak iki müellifin görüşlerini karşılaştırmıştır. Bu doğrultuda çalışmanın girişinde kurucu metin ile ne kastedildiği açıklanıp makalenin ilk bölümünde Safedî’nin şerhi, muhteva açısından incelenecektir. İkinci bölümde ise eser üzerine yapılan hâşiye ve ihtisar çalışmaları çerçevesinde Ġays̱ü’l-edeb’in kurucu rolü tartışılacaktır.

Authors: Anh Menh , Hanh Huy Perk
Published: September 2021

The purpose of this research is to conduct a marketing and revenue analysis of seaweed producers. This study takes a qualitative approach via the use of exploratory research techniques. This research included all farmers who grow seaweed. The Slovin formula was used to calculate the sample size, which was 40 heads of households. The sample is determined using a basic random sampling technique. While data gathering is accomplished via interviews, observation, and documentation. Farmers market their seaweed goods in two ways, first to middleman merchants, then to collectors, and lastly to inter-city traders. Second, farmers sell their produce to collectors, who subsequently distribute it to intercity merchants. The average revenue earned by seaweed growers. That is 6 USD –830 USD in a single manufacturing process, indicating that seaweed farming is lucrative and possible to expand, but that production expenses must be more efficiently used to achieve larger profits

We present the discovery of an 18.5 ± 0.5 M
Jup brown dwarf (BD) companion to the M0V star TOI–1278. The system was first identified through a percent-deep transit in Transiting Exoplanet Survey Satellite photometry; further analysis showed it to be a grazing transit of a Jupiter-sized object. Radial velocity (RV) follow-up with the SPIRou near-infrared high-resolution velocimeter and spectropolarimeter in the framework of the 300-night SPIRou Legacy Survey carried out at the Canada–France–Hawaii Telescope led to the detection of a Keplerian RV signal with a semi-amplitude of 2306 ± 10 m s−1 in phase with the 14.5 day transit period, with a slight but nonzero eccentricity. The intermediate-mass ratio (M
⋆/M
comp ∼ 31) is unique for having such a short separation (0.095 ± 0.001 au) among known M-dwarf systems. Interestingly, M-dwarf–BD systems with similar mass ratios exist with separations of tens to thousands of astronomical unit.

We present ZTF18aaqjovh (SN 2018bvw), a high-velocity (“broad-lined”) stripped-envelope (Type Ic) supernova (Ic-BL SN) discovered in the Zwicky Transient Facility one-day cadence survey. ZTF18aaqjovh shares a number of features in common with engine-driven explosions: the photospheric velocity and the shape of the optical light curve are very similar to those of the Type Ic-BL SN 1998bw, which was associated with a low-luminosity gamma-ray burst (LLGRB) and had relativistic ejecta. However, the radio luminosity of ZTF18aaqjovh is almost two orders of magnitude fainter than that of SN 1998bw at the same velocity phase, and the shock velocity is at most mildly relativistic (v = 0.06–0.4c). A search of high-energy catalogs reveals no compelling gamma-ray burst (GRB) counterpart to ZTF18aaqjovh, and the limit on the prompt GRB luminosity of

excludes a classical GRB but not an LLGRB. Altogether, ZTF18aaqjovh represents another transition event between engine-driven SNe associated with GRBs and “ordinary” Ic-BL SNe.

In addition to regular Schwabe cycles (≈11 yr), solar variability also shows longer periods of enhanced or reduced activity. Of these, reconstructions of the Dalton Minimum provide controversial sunspot group numbers and limited sunspot positions, partially due to limited source record accessibility. In this context, we analyzed Stephan Prantner’s sunspot observations spanning from 1804 to 1844, the values of which had only been known through estimates despite their notable chronological coverage during the Dalton Minimum. We identified his original manuscript in Stiftsarchiv Wilten, near Innsbruck (Austria). We reviewed his biography (1782–1873) and located his observational sites at Wilten and Waidring, which housed the principal telescopes for his early and late observations: a 3.5 inch astronomical telescope and a Reichenbach 4 foot achromatic erecting telescope, respectively. We identified 215 days of datable sunspot observations, which is almost twice as much data as his estimated data in the existing databases (=115 days). In Prantner’s records, we counted up to seven to nine sunspot groups per day and measured sunspot positions, which show their distributions in both solar hemispheres. These results strikingly emphasize the difference between the Dalton Minimum and the Maunder Minimum as well as the similarity between the Dalton Minimum and the weak solar cycles in the modern observations.

We report the detection of a massive neutral gas outflow in the z = 2.09 gravitationally lensed dusty star-forming galaxy HATLAS J085358.9+015537 (G09v1.40), seen in absorption with the OH+(11−10) transition using spatially resolved (0.″5 × 0.″4) Atacama Large Millimeter/submillimeter Array (ALMA) observations. The blueshifted OH+ line is observed simultaneously with the CO(9−8) emission line and underlying dust continuum. These data are complemented by high-angular-resolution (0.″17 × 0.″13) ALMA observations of CH+(1−0) and underlying dust continuum, and Keck 2.2 μm imaging tracing the stellar emission. The neutral outflow, dust, dense molecular gas, and stars all show spatial offsets from each other. The total atomic gas mass of the observed outflow is 6.7 × 109
M
⊙, >25% as massive as the gas mass of the galaxy. We find that a conical outflow geometry best describes the OH+ kinematics and morphology and derive deprojected outflow properties as functions of possible inclination (0.°38–64°). The neutral gas mass outflow rate is between 83 and 25,400 M
⊙ yr−1, exceeding the star formation rate (788 ± 300 M
⊙ yr−1) if the inclination is >3.°6 (mass-loading factor = 0.3–4.7). Kinetic energy and momentum fluxes span (4.4–290) × 109
L
⊙ and (0.1–3.7) × 1037 dyne, respectively (energy-loading factor = 0.013–16), indicating that the feedback mechanisms required to drive the outflow depend on the inclination assumed. We derive a gas depletion time between 29 and 1 Myr, but find that the neutral outflow is likely to remain bound to the galaxy unless the inclination is small and may be reaccreted if additional feedback processes do not occur.
The Impacts of Modeling Choices on the Inference of Circumgalactic Medium Properties from Sunyaev–Zeldovich Observations

Published: September 2021

As the signal-to-noise of Sunyaev–Zeldovich (SZ) cross-correlation measurements of galaxies improves our ability to infer properties about the circumgalactic medium (CGM), we will transition from being limited by statistical uncertainties to systematic uncertainties. Using thermodynamic profiles of the CGM created from the IllustrisTNG (The Next Generation) simulations we investigate the importance of specific choices in modeling the galaxy sample. These choices include different sample selections in the simulation (stellar versus halo mass, color selections) and different fitting models (matching by the shape of the mass distribution, inclusion of a two-halo term). We forward model a mock galaxy sample into projected SZ observable profiles and fit these profiles to a generalized Navarro–Frenk–White profile using forecasted errors of the upcoming Simons Observatory experiment. We test the number of free parameters in the fits and show that this is another modeling choice that yields different results. Finally, we show how different fitting models can reproduce parameters of a fiducial profile, and show that the addition of a two-halo term and matching by the mass distribution of the sample are extremely important modeling choices to consider.
Life in Elliptical Galaxies: Hot Spheroids, Fast Stars, Deadly Comets?
Authors: Lacki Brian C.
Published: September 2021

Elliptical galaxies have dynamically hot (σ
1D ∼100–300 km s−1) populations of stars, and presumably, smaller objects like comets. Because interstellar minor bodies are moving much faster, they hit planets harder and more often than in the local Galaxy. I estimate the rates for Chicxulub-scale impacts on an Earth-size planet in elliptical galaxies as a potential habitability constraint on intelligent life. Around most stars in a normal elliptical galaxy, these planets receive only ∼0.01–0.1 Gyr−1, although hazardous rates may be common in certain compact early-type galaxies and red nuggets. About ∼5% of the stellar mass is in a region where the rate is > 10 Gyr−1, large enough to dominate the mass extinction rate. This suggests that elliptical galaxies have an exclusion zone of order one hundred parsecs in radius around their centers for the evolution of intelligent life.
Threat from Within: Excitation of Venus’s Co-orbital Asteroids to Earth-crossing Orbits
Authors: Pokorný Petr , Kuchner Marc
Published: September 2021

All five currently known asteroids in the 1:1 mean-motion resonance (co-orbital) with Venus cross Earth’s orbit. We explore a scenario in which these near-Earth asteroids originate in a reservoir of asteroids co-orbiting with Venus on low-eccentricity orbits. Such an asteroid reservoir was proposed as the only viable source of Venus’s co-orbital dust ring. So far, efforts to discover low-eccentricity Venus co-orbital (LEVCO) asteroids have been unsuccessful; however, their existence has not been ruled out. We show that LEVCO asteroids, stable for millions to billions of years, eventually evolve into Earth-crossing configurations, where they may pose a threat to Earth. We find that the orbits of these asteroids cross Earth’s orbit for 22.5 million yr, on average, an order of magnitude longer than the corresponding Earth-crossing time of most asteroids escaping from the main belt. Using the results of the latest survey of LEVCO asteroids, we conclude that, given their absolute magnitudes, H, most of the observed Venus co-orbitals likely do not originate from the hypothetical population of LEVCO asteroids. However, we infer that there are up to ∼500 asteroids originating from the LEVCO region with H < 26.3 (10–40 m in diameter) that currently cross the orbit of Earth. Up to ∼20 of those have H < 24.1 (30–100 m in diameter), easily detectable by various near-Earth asteroid surveys. We estimate the current mass of the LEVCO reservoir as M ≈ 1013–1016 kg, 3–6 orders of magnitude lower than the current mass of the main belt, depending on their size–frequency distribution.

Cloud-based Software Platforms for Citizen Science: Implications and opportunities for biodiversity standards
Authors: Brenton Peter
Published: September 2021

Whether community created and driven, or developed and run by researchers, most citizen science projects operate on minimalistic budgets, their capacity to invest in fully featured bespoke software and databases is usually very limited. Further, the increasing number of applications and citizen science options available for public participation creates a confusing situation to navigate.

Cloud-based platforms such as BioCollect, iNaturalist, eBird, CitSci.org, and Zooniverse, provide an opportunity for citizen science projects to leverage highly featured functional software capabilities at a fraction of the cost of developing their own, as well as a common channel through which the public can find and access projects. These platforms are also excellent vehicles to facilitate the implementation of data and metadata standards, which streamline interoperability and data sharing. Such services can also embed measures in their design, which uplift the descriptions and quality of data outputs, significantly amplifying their usability and value.

In this presentation I outline the experiences of the Atlas of Living Australia on these issues and demonstrate how we are tackling them with the BioCollect and iNaturalist platforms. We also consider the differences and similarities of these two platforms with respect to standards and data structures in relation to suitability for different use cases. You are invited to join a discussion on approaches being adopted and offer insights for improved outcomes.
