Published: June 2020

Zusammenfassung
Anamnese Die 80-jährige Patientin stellte sich mit einer Arteria-carotis-Stenose links vor. Im Alter von 7 Jahren hatte sie unter Hämoptysen gelitten.
Untersuchungen und Diagnose Das EKG zeigte einen AV-Block II. Grades Typ Mobitz. Im Röntgenbild und Computertomogramm des Thorax imponierten eine Verlagerung des Mediastinums und des Herzens nach links, eine komplette Schrumpfung der linken Lunge sowie eine Überblähung der rechten Lunge. Die Lungenfunktionsanalyse ergab eine mäßige Restriktion. Es wurde die Diagnose Autopneumonektomie gestellt.
Therapie und Verlauf Eine Schrittmacherimplantation über die linke V. cephalica und eine Endarteriektomie der Arteria carotis links wurden komplikationslos durchgeführt.
Folgerung Resultiert nach Autopneumonektomie eine Obstruktion der Atemwege aufgrund der Mediastinalverschiebung, ist eine operative Revision erforderlich. Eine Antibiotikatherapie ist bei Atemwegsinfektionen indiziert. Punktionen der V. subclavia sind kontraindiziert, da eine Fehlpunktion zu einem kompletten Pneumothorax führen kann.

Published: June 2020

Abstract
Artemisia annua tea is a popular dosage form used to treat and prevent malaria in some developing countries. However, repeated drinking leads to an obviously decreased efficacy, which may be related to the induction of metabolizing enzymes by artemisinin. In the present study, the ability of different components in A. annua to activate the pregnane X receptor and constitutive androstane receptor was evaluated by the dual luciferase reporter gene system. The changes in mRNA and protein expression of CYP3A4 and CYP2B6 were determined by quantitative real-time PCR and Western blotting. Results showed that in the pregnane X receptor-mediated CYP3A4 reporter gene system, chrysosplenetin and arteannuin B exhibited a weak induction effect on pregnane X receptor wt, while arteannuin A had a strong induction effect on pregnane X receptor wt and pregnane X receptor 370 and a weak induction effect on pregnane X receptor 163. In the pregnane X receptor-mediated CYP2B6
reporter gene system, arteannuin A had a moderate induction effect on pregnane X receptor wt and pregnane X receptor 379, and a weak induction effect on pregnane X receptor 403, while arteannuin B had a weak induction effect on pregnane X receptor wt and pregnane X receptor 379. Arteannuin A had a strong induction effect on constitutive androstane receptor 3 in constitutive androstane receptor-mediated CYP3A4/2B6 reporter gene systems, while arteannuin B showed a weak induction effect on constitutive androstane receptor 3 in the constitutive androstane receptor-mediated CYP2B6 reporter gene system. The mRNA and protein expressions of CYP3A4 and CYP2B6 were increased when the pregnane X receptor or constitutive androstane receptor was activated. Various components present in A. annua differentially affect the activities of pregnane X receptor isoforms and the constitutive androstane receptor, which indicates the possibility of a drug-drug interaction. This partly
explains the decline in efficacy after repeated drinking of A. annua tea.
C–H Functionalization Strategies in the Naphthalene Series: Site Selections and Functional Diversity
Authors: Prim Damien , Large Benjamin 
Published: June 2020

Naphthalene is certainly not a common arene. In contrast to benzene, the bicyclic feature of naphthalene offers multiple differentiable positions and thus a broad diversity of substitution patterns. Naphthalene is a central building block for the construction of elaborated polycyclic architectures with applications in broad domains such as life and materials sciences. As a result, C–H functionalization strategies specially designed for naphthalene substrates have become essential to install valuable substituents on one or both rings towards polysubstituted naphthalenes. This short review provides a focus on uncommon substitution patterns; however, classical ortho C–H activation is not covered.1 Introduction2 C–H Functionalization Using a Directing Group Located at Position 12.1 Functionalization on the Ring Bearing the DG: 1,3-Substitution Pattern2.2 Functionalization on the Ring Bearing the DG: 1,4-Substitution Pattern2.3 Functionalization on the Neighboring Ring: 1,6-, 1,7- and 1,8-Substitution Patterns3 C–H Functionalization Using a Directing Group Located at Position 23.1 Functionalization on the Ring Bearing the DG: 2,4- and 2,1-Substitution Patterns3.2 Miscellaneous Substitution Patterns4 Bis C–H Functionalization4.1 Symmetrical Bisfunctionalization: 1,2,8-Substitution Pattern4.2 Symmetrical Bisfunctionalization: 2,3,1-Substitution Pattern4.2 Unsymmetrical Bisfunctionalization: 2,3,1-Substitution Pattern4.3 Symmetrical Bisfunctionalization: 2,4,8-Substitution Pattern5 Conclusion and Outlook
Simple tiles and attractors
Authors: Zaitseva T. I. 
Published: June 2020

AbstractWe study self-similar attractors in the space, that is, self- similar compact sets defined by several affine operators with the same linear part. The special case of attractors when the matrixof the linear part and the shifts of the affine operators are integer, is well known in the literature due to the many applications in the theory of wavelets and in approximation theory. In this case, if an attractor has measure one it is called a tile. We classify self-similar attractors and tiles in the case when they are either polyhedra or a union of finitely many polyhedra. We obtain a complete description of the matricesand the digit sets for parallelepiped tiles and for convex tiles in arbitrary dimensions. It is proved that on a two-dimensional plane, every polygonal tile (not necessarily convex) must be a parallelogram. Nontrivial examples of multidimensional tiles which are a finite union of polyhedra are given, and in the casea complete classification is provided for them. Applications to orthonormal Haar systems inand to integer univariate tiles are considered.Bibliography: 18 titles.

Published: June 2020

Abstract
We classify compact complex surfaces whose groups of bimeromorphic selfmaps have bounded finite subgroups. We also prove that the stabilizer of a point in the automorphism group of a compact complex surface of zero Kodaira dimension, as well as the stabilizer of a point in the automorphism group of an arbitrary compact Kähler manifold of nonnegative Kodaira dimension, always has bounded finite subgroups.

Significance
Catalysts are essential for a sustainable future because they reduce the energy required in chemical processes and the emission of harmful and polluting compounds. Revealing the function and structure of a working catalyst is a challenging task but critical in order to prepare more efficient and higher-performing materials. Very often, active sites are formed by many atoms that cooperate to perform the catalytic function. It is therefore challenging to identify the structure of the active site. Here, we combine uniform nanocrystal catalysts and theory insights to reveal the active-site ensemble necessary for alkene combustion. This approach can be extended to reveal atomistic details of working catalysts for a variety of applications.

Published: June 2020

SignificanceWhen a pathogen is engulfed by an immune cell, it is trapped in a transient organelle called the phagosome. The host cell recognizes the pathogen through receptors called Toll-like receptors (TLRs) that each recognize specific pathogen-associated molecular pattern (PAMP). When a TLR recognizes its cognate PAMP, it activates inducible nitric oxide synthase (NOS2), filling the phagosome with NO and destroying the pathogen. By developing a fluorescent reporter that directly images PAMP-triggered NOS2 activity in real time, we show that single-stranded RNA acts as a PAMP in zebrafish by activating its cognate TLR. Such a technology can help identify new PAMPs, pinpoint ligands for TLRs of unknown function, and suggest how PAMPs might synergize to help bugs evade the phagosomal deathtrap.
The infalling photon, the infalling particle, and the observer at rest near the horizon of a black hole
Authors: Mazzitelli Francisco D 
Published: June 2020

Abstract
When a massive test particle or a photon fall radially into a black hole, their energy, as measured by a static observer located very close to the horizon, diverges. In introductory courses on general relativity, this fact gives rise to questions about the reality of this divergence and its eventual effect on the geometry of the black hole. We address these concerns and show that, eventually, it is the observer at rest who may induce corrections to the metric, unless its mass is crucially small when located near the horizon.
Effect of phonons on the electron spin resonance absorption
spectrum
Authors: Norambuena Ariel , Jimenez Alejandro , Becher Christoph , Maze Jerónimo R 
Published: June 2020

Abstract
The unavoidable presence of vibrations in solid-state devices can drastically
modify the expected electron spin resonance (ESR) absorption spectrum in
magnetically active systems. In this work, we model the effect of phonons and
temperature on the ESR signal in molecular systems with strong
E ⊗ e Jahn–Teller (JT)
effect and an electronic spin-1/2. Our microscopic model considers the linear JT
interaction with a continuum of phonon modes, the spin–orbit coupling,
the Zeeman effect, and the response of the system under a weak oscillating
magnetic field. We derive a Lindblad master equation for the orbital and spin
degrees of freedom, where one- and two-phonon processes are considered for the
phonon-induced relaxation, and the thermal dependence of Ham reduction factors
is calculated. We find that the suppression of ESR signals is due to phonon
broadening but not based on the common assumption of orbital quenching. Our
results can be applied to explain the experimentally observed absence of the ESR
signal in color centers in diamond, such as the neutral nitrogen-vacancy and
negatively charged silicon-vacancy color centers in diamond.
Laboratory Compaction Method of Soft Clay and Natural Plant Fiber/Shell Mixtures
Authors: Firmana Arifin Yulian , Misnawati  , Ridha Muhammad 
Published: June 2020

Abstract
One method of soil stabilization is to mix the soil with natural materials such as fibers or shells from plants. Generally, the samples are compacted in a laboratory by mean of Standard and Modified Proctor Compaction tests. The results of compaction are the relationship between water content and density, as indicated by the dry unit weight of the samples. In principle, this compaction process reduces the pore space filled with air in the soil. In this condition, soil is not saturated with water. The method cannot be used to compact soils that are in water-saturated conditions such as soft clay soils which are commonly found in wetland areas. This paper focuses on describing methods for compacting soft clay mixed with additional materials such as fibers and shells from plants. Two steps must be taken to compact samples of mixed soil and natural material. Firstly, determining the percentage of the mixture at which the sample can be compacted, and secondly, determining the optimum fiber/shell content to produce maximum density. The equipment and energy used are the same as the Proctor standard compaction test. Examples of calculations and results obtained for each material (i.e., empty fruit bunches and oil palm shells) are presented and discussed in the paper. Compaction procedures in the laboratory for the mixture of soft clay and other materials are also suggested in the paper.
Water management on peatland for food crop and horticulture production: research review in Kalimantan
Authors: Hairani A , Noor M 
Published: June 2020

Abstract
Water management is the most important component in developing peatlands for agriculture. Utilization of peatlands for food crops and research on its physical, chemical and biological characteristics have been carried out previously since a long time. However, the implementation of peatland management technology is not much well known. Peatland agricultural commodities are developing. In 1970-1990, mostly for food crops and horticulture. Since 2000 plantation crops had been developed rapidly. About 0.5-0.8 million ha of peatlands are planted by food crops, including horticulture and 2.5-3.0 million ha for oil palm. The use of peatlands is still being debated along with threats to the environment, especially greenhouse gas (CO2) emissions. The use of peatlands for agriculture by local communities aimed at sustaining life and has an interesting long history. Farmers who live in peatlands have special abilities and expertise in peatland management. Based on this experience and local wisdom, the government then planned to open peatlands, especially in supporting transmigration programs from Java, Nusa Tenggara, and Bali. However, the use of peatlands for agriculture has changed the fertility of peatlands and reported to be a trigger for land degradation so that improvement efforts are needed. The government has also issued several policies in improving the management and conservation of peatlands. This paper is a review of the results of research and experience on water management on peatlands for food crop and horticulture production.

Authors: Jain Vipul , Mittal Mohit , Chaudhary Rajiv 
Published: June 2020

Abstract
The components of an automobile are usually made up of steel and its alloy which leads to an increase in consumption of fuel. Moreover, a large amount of non-recyclable waste is being produced by the automotive sector. Therefore, it becomes necessary to move towards the lightweight, environment-friendly, and sustainable material which can replace the existing ones. In this regard, the current research work is focused on the pineapple leaf and glass fiber reinforced hybrid epoxy composite to be used for automotive car bumper. The bumper of Ambassador Car was designed in CATIA V5R18 and analyzed in ANSYS18.1. It was found that the geometrical optimization is an important parameter in structural strength improvement. The strength of automotive bumper was increased significantly after providing the strengthening ribs, changing the cross-section, and increasing the thickness. For static and impact analysis, the biocomposite bumper exhibits a lower value of deformation and higher value of strength than the steel and aluminium ones. The results of analysis and reduction in the mass of bumper have proved that the hybrid biocomposite material has significant potential for automotive structural components.
Design, development and analysis of a magnetorheological damper
Authors: Khuntia Satvik , Yadav Rithik , Singh R C , Rastogi Vikas 
Published: June 2020

Abstract
Magnetorheological Dampers or MR Dampers are advanced shock absorbers known for their fast response rate, wide dynamic range, mechanical simplicity and low power requirement. MR dampers use smart fluids called MR Fluids which can change dynamic yield stress when acted upon by a magnetic field. The damping force is changed by varying the rheological properties of the fluid magnetically. MR dampers are usually used in high-end automobiles. In this paper, an attempt has been made to make an alternative damper to the existing high-priced MR dampers which can be used in the mid-segment vehicles of today. A new design is proposed by the authors which incorporate the flow of the MR fluid through a hollow passage and focuses on making use of the strong magnetic field created at its center. Silicone oil as a carrier fluid, Carbonyl Iron power and White lithium grease as an additive are selected after studying fluid components. Before fabrication of the new design, numerical calculations are made to evaluate the strength of the magnetic field that is needed to provide suitable yield stress. A permeability around 3000 NA−2 is expected. This is estimated from the B-H curve for a commercial MR fluid called MRF - 32D. It is noted that a 43 SWG is the most suitable for the damper and with 4 - 5 windings, a maximum induced field of 1.2T (theoretically) can be produced at the center of the primary fluid column. This fluid column exists to a length of 80 mm while the coiling spanned up to 65 mm of the column. It is also concluded that these design parameters will be sufficient to create a strong magnetic field which can exert enough yield stress to give the desired results needed for damping.
