Modes of magnetic field generation in the low-mode αΩ-dynamo model with dynamic regulation of the α-effect by the field energy
Authors: Шереметьева О.В. 
Published: December 2021

В работе используется маломодовая модель αΩ-динамо для моделирования режимов генерации магнитного поля при незначительных изменениях поля скорости вязкой жидкости. В рамках этой модели интенсивность α-эффекта регулируется процессом с памятью, который вводится в магнитогидродинамическую систему (МГД-система) как аддитивная поправка в виде функционала Z(t) от энергии поля. В качестве ядра J(t) функционала Z(t) выбрана функция, определяющая затухающие колебания с варьируемым коэффициентом затухания и постоянной частотой затухания, принятой равной единице. Исследование поведения магнитного поля проводится на больших временных масштабах, поэтому для численных расчётов используется перемасштабированная и обезразмеренная МГД-система, где в качестве единицы времени принято время диссипации магнитного поля (104 лет). Управляющими параметрами системы выступают число Рейнольдса и амплитуда α-эффекта, в которых заложена информация о крупномасштабном и турбулентном генераторах. Результаты численного моделирования режимов генерации магнитного поля при различных значениях коэффициента затухания и постоянной частоте затухания отражены на фазовой плоскости управляющих параметров. В работе исследуется вопрос о динамике изменения картины на фазовой плоскости в зависимости от значения коэффициента затухания. Проводится сравнение с результатами, полученными ранее при постоянной интенсивности α-эффекта и при изменении интенсивности α — эффекта, которое определялось функционалом Z(t) с показательным ядром и аналогичными значениями коэффициента затухания.In this paper, we use a low-mode αΩ-dynamo model to simulate the modes of magnetic field generation with insignificant changes in the velocity field of a viscous fluid. Within the framework of this model, an additive correction is introduced into the magnetohydrodynamic system to control the intensity of the α-effect in the form of a function Z(t) from the field energy. As the kernel J(t) of the function Z(t) is chosen the function that determines damped oscillations with the different values of the damping coefficient and a constant damping frequency taken equal to one. The study of the magnetic field behavior is carried out on a large time scales, therefore, for numerical calculations, a rescaled and dimensionless MHD-system is used, where the time of the magnetic field dissipation (104 years) is accepted as the unit of time. The main parameters of the system are the Reynolds number and the amplitude of the α-effect, which contains information about the large-scale and turbulent generators, respectively. According to the results of numerical simulation, an increase in the values of the damping coefficient is characterized an increase in the inhibition effect of the process Z(t) on the α-effect and decrease of the magnetic field divergence region on the plane of the main parameters.

На примере серий лягушки травяной из четырех биотопов, характеризующихся разной степенью пространственной изоляции, показана перспективность изучения биохорологической структуры данного вида с применением фенетического подхода. Наиболее детальную характеристику пространственно-генетической структуры можно получить при анализе пятнистости дорзальной поверхности тела. Так же для этих целей возможно использование вариаций таких элементов рисунка покровов тела, как форма межлопаточного пятна и число полос на бедре.
The prospects of studying the biochorological structure of the selected species using a phenetic approach are shown in a series of common frogs from four biotopes characterized by varying degrees of spatial isolation. The most detailed characterization of the spatial-genetic structure can be obtained by analyzing the spotting of the dorsal surface of the body. Also, for these purposes, it is possible to use variations of such elements of the body covering pattern as the shape of the interscapular spot and the number of stripes on the thigh.

AbstrakPenelitian ini bertujuan untuk mengetahui gejala sosial yang terdapat dalam tiga cerpen Kalimantan Timur tahun 1980-an. Ketiga cepen tersebut berjudul “Kembali ke Desa”, Surat dari Kekasih”, dan “Keping Hati Menguak Badai”. Dengan teori sosiologi sastra, penelitian ini menganalisis berbagai gejala sosial yang terjadi dalam relasi tokoh dengan lingkungannya. Analisis menunjukkan bahwa gejala sosial yang terjadi pada ketiga cerpen tersebut berupa tokoh yang melakukan pertahanan eksistensinya dengan bermigrasi ke luar daerahnya. Di daerah baru tersebut tokoh mengalami konflik-konflik selama melakukan pertahanan eksistensi. Konflik-konflik yang terjadi menimbulkan tokoh mengambil keputusan untuk kembali ke daerahnya. Selain konflik-konflik, terdapat pula nilai-nilai sosial yang ditampilkan dalam relasi antarindividu. Nilai-nilai tersebut yaitu solidaritas dan empati. Analisis juga menunjukkan pula terdapat tujuan tokoh melakukan pertahanan eksistensi ke luar daerahnya bukan hanya untuk meningkatkan status ekokonomi dirinya, melainkan untuk kembali dan membangun daerahnya yang belum mengalami kemajuan. Tiga cerpen Kalimantan Timur tahun 1980-an menunjukkan gejala sosial manusia melalui pergulatan pertahanan eksitensi di luar daerahnya.Kata kunci: fenomena sosial, eksistensi, migrasiAbstract This study aims to determine the social phenomena in three East Kalimantan short stories in the 1980s. Those are “Kembali ke Desa”, “Surat dari Kekasih”, and “Keping Hati Menguak Badai”. Using the theory of literature sociology, this research analyzes various social phenomena in characters’ relationship with their environment. The analysis shows that the social phenomena in those short stories are characters who defend their existence by migrating from his or her place.In their new environment, the characters experience conflicts while fighting for their existence. Those conflicts make them return to their old place. In addition, there are also social values portrayed in relationships between individuals, solidarity and empathy. The analysis also reveals that there is a purpose in defending their existence away from their home, not only to improve their economic status, but also to return and make their environment a better place. Those three short stories show social phenomena through the struggle of defending existence away from their environment. Keywords: social phenomena, existence, migra

Published: December 2021

Abstrak Bahasa Banjar sebagai bahasa ibu bagi masyarakat Banjar di Kalimantan Selatan saat ini sedang mengalami pergeseran pemakaian akibat pengaruh globalisasi. Hal itu menyebabkan diperlukannya upaya pemertahanan bahasa Banjar di tengah masyarakat. Oleh sebab itu diperlukan banyak media sebagai sarana pemertahanan Bahasa Banjar melalui pelestarian kearifan lokal dalam tradisi lisan Banjar itu sendiri. Hal itu disebabkan media penyampai tradisi lisan Banjar adalah Bahasa Banjar. Hal itu berarti pelestarian kearifan lokal dalam tradisi lisan Banjar secara tidak langsung merupakan pemertahanan Bahasa Banjar itu sendiri. Oleh sebab itu, penelitian ini didasarkan pada dua tujuan penting, yaitu untuk mengetahui media-media penyampai kearifan lokal tradisi lisan Banjar dan untuk mengetahui tradisi lisan apa saja yang dapat digunakan untuk melestarikan bahasa ibu sebagai bentuk pelestarian kearifan lokal pada masyarakat Banjar yang ada di Kalimantan Selatan. Adapun masalah dalam penelitian ini adalah apa sajakah media-media yang dapat digunakan pemertahanan bahasa ibu melalui tradisi lisan dan jenis tradisi lisan apa saja yang dapat digunakan dalam pelestarian bahasa ibu sebagai wujud pelestarian kearifan lokal yang ada pada masyarakat Banjar di Kalimantan Selatan. Penelitian ini menggunakan metode deskriptif kualitatif dengan teknik studi pustaka. Berdasarkan hasil analisis dapat diketahui bahwa media-media yang dapat digunakan adalah: 1) menggunakan televisi sebagai sarana pelestarian tradisi lisan Banjar; 2) membuat lomba-lomba penciptaan sastra tradisi dengan menggunakan bahasa daerah; 3) membuat karya sastra tradisi pada saat pembelajaran mulok di sekolah dengan menggunakan bahasa daerah; 4) Pendokumentasian bahasa Banjar dan tradisi lisannya; 5) melakukan sosialisasi kepada para sastrawan, pelajar, dan budayawan mengenai pentingnya penggunaan bahasa daerah dalam penciptaan karya sastra sebagai bentuk pelestarian bahasa daerah dan kearifan lokal. Adapun tradisi lisan yang masih dapat digunakan untuk pelestarian bahasa daerah dan kearifan lokal adalah tradisi lisan yang masih hidup ditengah masyarakatnya, seperti: pantun, paribasa, dan cerita rakyat.

Published: December 2021

Sweet potato (Ipomoea batatas L., Lam.) is one of the most frequently eaten food crops. Its production is affected by plant-parasitic nematodes as well as biotic factors. This study was conducted to document the different plant-parasitic nematodes (PPN) that limit the gainful production of sweet potato in Gombe State. Thirty soil core samples per hectare were collected at random from sweet potato farms in the three local government areas (Nafada, Kaltungo, and Yamaltu Deba) of Gombe state. The Whitehead and Hemming method and identification keys were used for the soil extraction and genera identification of the plant-parasitic nematodes respectively. A total of 15 plant-parasitic nematodes were recovered throughout the surveyed areas among which 7 are considered major nematode pests of global importance. Irrespective of the surveyed locations, Meloidogyne spp., was found to record the highest population density and prevalence value. The frequency of occurrence in Y/Deba and Nafada LGAs shows that Meloidogyne spp., wasthe most occurring (32 %) genera. In Kaltungo LGA however, Scutellonema spp., and Rotylenchusspp., were the most occurring (17 %) genera. There was a high similarity percentage (≥ 68 %) of PPN genera where 8 genera (Scutellonema spp., Nacobbus spp., Pratylenchus spp., Meloidogyne spp., Heterodera spp., Xiphinema spp., Trichodorus spp., and Rotylenchus spp.) were found to be common amongst the surveyed locations. This is the first report of plant-parasitic nematodes associated with sweet potato in Gombe state, Nigeria. Hence, it is critical to educate farmers in the regions about their effects on the crop and how to successfully manage them.
Purpura Fulminans in a 20-Year-Old Female

Published: December 2021

A previously healthy 20-year-old female presented with extensive retiform purpura located at the face, upper and lower limbs, one week after an episode of acute tonsillitis. Despite the exuberance of the cutaneous findings and progression to skin necrosis she had no accompanying symptoms. Laboratory investigation revealed a heterozygous protein C mutation (exon 9, c.1332G> C, p.Trp444Cys), accounting for a partial deficiency of this anticoagulant protein. The patient was started on broad spectrum antibiotics, anticoagulation and systemic corticosteroids, with no lesional progression and complete resolution of cutaneous ulceration within 6 months.
This is a singular case of purpura fulminans, since two different causative factors precipitated the events. The previous tonsillitis reported by the patient is significant, because the serum concentration of protein S may also decrease after an infectious event - post-infectious purpura fulminans. This case illustrates that purpura fulminans due to autoantibodies against protein S, although rare, should be considered, especially in the absence of a severe acute infection. It also illustrates how in a given patient different independent factors can act simultaneously, triggering potentially devastating clinical scenarios.
Zoon Balanitis and Lichen Sclerosus: An Uncommon Association
Authors: Garrido Pedro Miguel , Aguado-Lobo Marta , Soares de Almeida Luís , Borges da Costa João 
Published: December 2021

Zoon balanitis and lichen sclerosus are both chronic inflammatory disorders of the genital mucosa that usually affect middle-aged or elderly uncircumcised men.Although the precise etiology of Zoon balanitis is still unclear, a pathogenic role of irritant and mechanical factors has been suggested. Therefore, foreskin sclerosis and phimosis caused by male genital lichen sclerosus may trigger the development of Zoon balanitis. However, until the present, only three cases with clinical and histopathologic features consistent with synchronous presentation of both disorders have been described.
We report the case of a 70-year-old male who developed Zoon balanitis in association with lichen sclerosus, that cleared only after circumcision.

A criptococose é uma infecção sistémica causada por Cryptococcus neoformans, levedura oportunista encapsulada. Esta infeção ocorre principalmente em indivíduos imunocomprometidos e os sintomas variam de acordo com a integridade do sistema imunológico. A criptococose cutânea afeta aproximadamente 20% dos pacientes com criptococose disseminada, mas a criptococose cutânea primária (PCC) sem infecção sistémica é rara.
Um paciente do sexo masculino de 76 anos, com doença pulmonar obstrutiva crónica, hipertensão arterial e dislipidemia, apresentou-se com placa cutânea inflamatória violácea com bolhas que progrediu apesar de ceftriaxone endovenoso por 7 dias, sem sucesso. A biópsia incisional revelou o diagnóstico histopatológico de criptococose cutânea. As lesões resolveram após tratamento com fluconazol 300 mg/dia durante 3 meses. Não se detectou doença sistémica e não havia qualquer evidência de imunossupressão.
Enfatiza-se a importância da inclusão da criptococose cutânea no diagnóstico diferencial das lesões cutâneas, mesmo em pacientes sem terapia imunossupressora. As manifestações cutâneas da infecção podem ser o primeiro indício para uma doença disseminada, pelo que o seu reconhecimento precoce é fundamental para um bom prognóstico.
