Upper Devonian brachiopods from the core of the Kurgan-Uspenskaya-1 key borehole (south-western outlying areas of Western Siberia)
Authors: Mizens A. G. , Mizens L. I. 
Published: August 2021

Research subject. Brachiopods from the core of the Kurgan-Uspenskaya-1 parametric borehole. The borehole was drilled in the south of Western Siberia 80 km southeast of the Kurgan town. Brachiopods were collected at a depth of 1,525.4 m in the IV tectonic block (core interval 1,450–1,794 m) in the greenish-gray marls of the Famennian stage of the Upper Devonian.Materials and methods. The paleontological material is presented in the form of complete undamaged shells and individual valves of small- and medium-sized brachiopods. The safety of brachiopods makes it possible to determine their species and genera, sometimes in open nomenclature. The article provides a brief description of the available material.Results. 11 species of brachiopods of the subtype Rhynchonelliformea belonging to six orders and nine genera were identified. The following ten species were described: Orbinaria fallax (Pand.), Semiproductus amplus Bubl., Schuchertella sp., Dalejina? sp., Camarotoechia panderi (Sem.et Moell.), C. volucera Nal., Athyris tobolica Nal., Cleiothyridina tenuilineata (Row.), Cl. ex gr. pectinata (Sem. et Moell.), Retzia? sp. The presented information allows conclusions about the age of the sediments enclosing the brachiopods under study and expands the existing knowledge of both the composition of the Upper Famennian brachiopods of the basement of the south of Western Siberia and their geographical and stratigraphic distribution.Conclusion. An analysis of the stratigraphic distribution of the described brachiopods taking into account data on foraminifera allowed us to determine the age of the host rocks as the very top of the Famennian stage. The composition of the brachiopods allows these rocks to be correlated with coeval deposits of the East European Platform, Timan, the Urals, Kuzbass, the Gorny Altai, Kazakhstan and North America.

Background:
We reviewed the clinical outcomes of a procedure that combines endovascular embolization and a direct surgical approach in a hybrid operating room (OR) for the treatment of refractory dural arteriovenous fistulas (dAVFs).

Methods:
All patients with intracranial dAVFs who underwent a procedure combining endovascular embolization and direct surgical approach with biplane angiography or a robotic C-arm system in a hybrid OR between February 2004 and June 2020 were considered. Borden grading, occlusion rate, pre-and post-operative modified Rankin Scale (mRS) scores, and complications were retrospectively investigated. The pre-and postoperative mRS scores were compared using the Wilcoxon signed-ranks test.

Results:
We evaluated 14 arteriovenous fistulas (AVFs) in consecutive 13 patients. Of these, ten AVFs were previously treated with endovascular embolization, ten were located in the transverse-sigmoid sinus, and four in the cortical vein. The Borden grade was II in two AVFs and III in 12 AVFs. Immediate occlusion of the AVF was achieved in 13 AVFs, and gradual occlusion was observed in one case. The median preoperative mRS was 1 (0–3), whereas the median postoperative mRS was 0 (0–1) which indicated marked improvement (P = 0.006). Complications including postoperative transient visual disturbance and intraprocedural extravasation were observed in only two cases.

Conclusion:
The combination of endovascular embolization and direct surgical approach in a hybrid OR could achieve sufficient occlusion of refractory AVFs with acceptable complication rates and improved symptoms.
Microsurgical resection of a giant cervico-medullary ependymoma: 2D-dimensional video
Authors: Oberman Dan Zimelewicz , Machado Raphael , Ribeiro Luiz Felipe , Von Zuben Daniela de Oliveira , Bahia Paulo Alves , Schiavini Hugo Corrêa , Monteiro Ruy 
Published: August 2021

Background:
Ependymoma is a slowly growing benign neoplasm that constitutes 3–9% of all neuroepithelial spinal cord tumors.[3,4] They rarely involve the cervicomedullary junction where they both compress the distal brainstem and upper cervical cord. Due to the critical contiguous structures, gross total resection of these lesions may result in significant morbidity/mortality.[1,2] Utilizing intraoperative neuromonitoring can help limit the risks of removing these lesions. Not when considering the risk/complications of partial versus total resection, the surgeon should keep in mind that they are benign slow growing tumors with relatively good long-term survivals following partial removals. This surgical video shows the surgical strategy and management of a giant cervicomedullary ependymoma performed in a 23-year-old female.

Case Description:
A 23-year-old female presented with cervical pain and quadriparesis of 1-year’s duration. The MR with/without gadolinium showed a large intradural, intramedullary cervical spinal cord tumor that severely expanded the spinal cord. It contained a significant cystic component, extending from the lower brain stem to the inferior aspect of C7. The lesion was hyperintense on T1 and T2 sequences and demonstrated minimal contrast enhancement. Surgery warranted a posterior cranio-cervical midline approach consisting of a suboccipital craniectomy with laminotomy. The pathological diagnosis was consistent with an ependymoma (WHO I). Fifteen days postoperatively, the patient was discharged with a minimal residual quadriparesis that largely resolved within 6 postoperative months. Three months later, the MRI confirmed complete tumor removal of the lesion. Notably, longer-term follow-up is warranted before complete excision can be confirmed. If there is a recurrence, repeat resection versus stereotactic radiosurgery may be warranted.

Conclusion:
This video highlights a safe and effective surgical technique for the resection of a giant cervicomedullary ependymoma.

Description of the subject. Pericopsis elata (Fabaceae) is a long-lived light-demanding tree from African rain forests that produces timber of high economic value. Natural populations suffer from overexploitation and a deficit of natural regeneration. Plantations could increase its production and limit the pressure on natural forests. However, we lack knowledge on the influence of spacing and seed tree origin on tree growth to optimize plantation protocols. Objectives. This study evaluated the impact of sapling density and seed tree origin on the growth in diameter and height of P. elata plants, 20 months after plantation. Method. Seeds were collected on 19 mother trees in a 400 ha natural stand near Kisangani (DRC). In October 2017, seedlings were transplanted in a Nelder design plantation with three replicates, to compare sapling growth at 10 contrasting plant densities under full sun. Diameter and height increments of 540 plants were analyzed according to local competition and maternal origin using generalized additive models. Results. Twenty months after planting, height growth peaked at an intermediate density of 47,000 stems·ha-1 (165.6 ± 39.2 cm·year-1), while diameter growth peaked at a lower density of 4,200 stems·ha-1 (24.6 ± 8.3 mm·year-1). The maternal origin of saplings affected their growth, the coefficients of variation among mother trees reaching 7.6% and 6.4% for diameter and height increments, respectively. The initial diameter affected positively diameter growth while the initial height did not influence height growth. Conclusions. The Nelder design proved useful to assess how plant growth depends both on spacing and genetic factors.

Introduction. Le moustique Aedes aegypti, vecteur majeur d’arbovirus, se développe dans un large panel de réservoirs artificiels en zone urbaine. Ces gîtes larvaires sont exposés à des conditions biotiques et abiotiques variables pouvant influencer la capacité vectorielle du moustique adulte et, par conséquent, le risque de transmission de pathogènes. Ici, nous recensons l’état des connaissances sur les propriétés physico-chimiques et microbiologiques des habitats aquatiques d’Ae. aegypti qui affectent le comportement de pré-oviposition, le développement et la capacité à transmettre les virus de ce Culicidae. Littérature. La grande variabilité spatio-temporelle des propriétés abiotiques et biotiques des gîtes d’Ae. aegypti rend complexe leur caractérisation. Certains facteurs biotiques (matière organique, larves congénères, microbiote) et abiotiques (salinité, température, pH) des gîtes ont des effets forts et directs sur le développement des larves et se répercutent sur les caractéristiques physiologiques et morphologiques du moustique adulte telles que la taille, la fécondité, la longévité et sa capacité vectorielle. Conclusions. Au vu de l’influence du gîte larvaire, et notamment de son microbiote, sur des nombreux traits phénotypiques chez Ae. aegypti, des efforts sont encore requis pour mieux comprendre comment la variabilité naturelle des gîtes façonne la capacité vectorielle des populations de cette espèce invasive à travers le globe.

Abstract

Air pollution is a process that causes changes in the composition of air from normal conditions, resulting in changes in air temperature. Air pollution is not only bad for health, but also has a negative impact on the environment. Currently, the Indonesian Railways Polytechnic has an Inspection Train which is not equipped with a device capable of reducing exhaust emissions. In this study, a particulate reducer was designed to reduce exhaust emissions on the Inspection Train. Furthermore, the design results were tested on the Inspection train, using 3 types of diesel fuel, namely Pertamina Dex, Dexlite, and Biosolar. This study shows that the particulate reducer designed in this study can significantly reduce emissions, namely 23.9% for Pertamina Dex fuel, 17.9% for Dexlite fuel, and 10.6% for Biosolar fuel.

Keywords: particulate reducer; air pollution; air temperature; diesel fuel.

ABSTRAK Permasalahan penelitian adalah mengapa wacana tentang pendalungan dimunculkan berulang-ulang dan bagaimana efek kuasa/pengetahuan dari sisi lain wacana pendalungan. Tujuan dari penelitian ini bermaksud untuk menjelaskan kuasa/pengetahuan dalam rangka pembentukan identitas orang Jember melalui pewacanaan pendalungan dan menjelaskan efek yang timbul dari wacana. Manfaat teoritisnya dalam mengembangkan kajian antropologi tentang konsep identitas berkaitan pendalungan beserta efeknya, khususnya dalam pembentukan identitas dengan pendekatan wacana kuasa/pengetahuan. Manfaat praktisnya sebagai masukan kepada masyarakat dan pemerintah dalam melakukan pengembangan tentang identitas warga Jember. Metode penelitian adalah kualitatif menggunakan instrumen studi pustaka dan wawancara. Populasi penelitian adalah seniman, akademisi dan sejarawan. Variabel penelitian berupa identitas, imajinasi dan multikultural. Hasil penelitian menemukan bahwa identitas bukan lahir dari sebuah situasi yang harmoni dan keseimbangan, melainkan pergulatan,kontestasi, benturan, beradu argumen dan wacana, pergesekan, dinamis dan produktif. Berkaitan dengan itu, simpulan penellitian ini bahwa identitas bukan suatu hal yang tetap melainkan bersifat lentur dan cair atau beragam.Kata Kunci: Pendalungan, imajinasi, identitas, wacana ABSTRACT The research problem formulated within this study is the question of why the pendalungan discourse was repreatedly surfaced and how is the influence of power/knowledge from the other side of this very discourse. This study seeks to unfold the essence of power/knowledge in forming the identity of the people of Jember through the pendalungan discourse as well as to provide an elaboration of the resulted effect from said discourse. The theoretical implication of this study would be the development of anthropological studies concerning the identity and influence of pendalungan, particularly on the formation of identity through the approach of power/knowledge discourse. As for the practical implication, the outcome of this study could serve as a form of valid recommendation both for the people and government in pursuing the development of the identity of Jember people. Drawing upon artists, academics, and historians as the population, this study made use of qualitative approach as the main method as well as literature review and interview as the instrument. A number of variables involved within this study were identity, imagination, and multiculturalism. The result of the study revealed that identity is not to be regarded as an entity born from a harmonious and balanced situation, rather, from an atmosphere that is full of struggles, contestation, clashes, conflicts of arguments and discourse, frictions between parties, dynamics, as well as productivity. From this point, this study embarked upon a conclusion that identity is not something that is fixed or rigid, but flexible and diverse.Keywords: Pendalungan, imagination, identity, discourse
