Die Architektur der Sternwarte auf Gut Bothkamp von 1869
Authors: Waschull Nadine
Published: December 2023

Probably ›always‹ were people interested in the sky and watched the stars. The continuous progress of telescopes not only led to ever-changing uses of the stars, but also the instrument’s susceptibility to damage
and bad pictures. Therefore, massive and useful locations were needed. In 1869 the Chamberlain Friedrich Gustav von Bülow – who wasn’t an astronomer himself – built on his estate’s edge in Bothkamp, Northern Germany,
a private observatory, surrounded by water and open sky on a filled headland. Not only the location or it housing Europe’s biggest telescope were kind of unusual, but the observatory’s appearance and architecture.
It was a rotunda with a hollow column in the middle on which the telescope stood, surrounded by eight rooms same size. The building had a gothic looking entrance, a walkable terrace with balustrade on the ground
floor and a rotatable cone-type roof on the upper floor, which could be opened by an elongated flap. Bothkamp was one of just a few private observatories, which generally had little architectural design. Since it
lacked the typical dome or at least a tower, it looked different anyway. Although Northern Germany had become Prussian at the time of building, the observatory’s appearance doesn’t correspond to the Berlin School
at all. Additionally, there was the uncommon use as a multi-purpose building and the representative interior design. Since the astronomical research in Bothkamp ended with World War I and the building was pulled
down in the 1930s, the article presents the observatory based on old views and reconstructions and classifies it within contemporary observatories and other buildings.

Published: December 2023

We study the investment incentives created by truthful mechanisms that allocate resources using approximation algorithms. Some approximation algorithms guarantee nearly 100% of the optimal welfare in the allocation problem but guarantee nothing when accounting for investment incentives. An algorithm's allocative and investment guarantees coincide if and only if its
confirming negative externalities are sufficiently small. We introduce fast approximation algorithms for the knapsack problem that have no confirming negative externalities and guarantees close to 100% for both allocation and investment.
Sampling Duration and Season Recommendations for Passive Acoustic Monitoring of Bats after White-Nose Syndrome
Authors: Hauer Christopher L. , Shinskie Jamie L. , Brady Rebecca J. , Titus Cassidy N.
Published: December 2023

Since 2006, white-nose syndrome has caused drastic declines in populations of several hibernating bat species throughout eastern North America. Thus, there is a growing need to establish long-term monitoring programs to assess changes in bat populations over time. Information on the seasonal timing of species occurrence and the sampling effort required to acoustically detect individual bat species and obtain complete inventories will enable researchers to design and implement more effective monitoring programs. From April to October 2018 to 2021, we passively sampled for bats using full-spectrum detectors at eight permanent sites at Fort Indiantown Gap National Guard Training Center, Pennsylvania. We examined seasonal activity patterns and estimated bat species richness among sites and seasons using species accumulation curves. We also estimated probability of detection (p) and site occupancy (Ψ) using single-season occupancy models in PRESENCE software and then determined the minimum number of sampling nights needed to reliably infer the absence of each species. We identified 286,131 bat passes of eight species in 4,107 detector-nights. Seasonal patterns of activity varied among species. We needed approximately 20 sampling nights to detect 90% of the total bat species richness among sites, and we needed 4 to 10 nights to detect 90% of species richness among seasons. We needed relatively few nights (≤12 nights) to detect most species during summer; however, we needed many more nights to detect acoustically rare species. Our results indicate that the acoustic sampling effort currently required to determine the presence or probable absence of Indiana myotis Myotis sodalis, northern long-eared myotis M. septentrionalis, and tricolored bats Perimyotis subflavus during summer may not be adequate for these species in some areas and that a considerable level of effort (>40 nights) is needed to detect little brown myotis M. lucifugus. Monitoring programs that incorporate efficient sampling methodologies will be critical for future conservation efforts as populations of several bat species continue to decline.
Determination of the (New) Product Dimensional Window
Authors: Gelten Peter
Published: December 2023

An important aspect of New Product Development (NPD) is the determination of the expected product dimensional window, describing the maximum strip width, that can be produced for a given strip thickness. The estimation of the product dimensional window is used to safely execute first rolling trials. In addition, one can verify in advance whether customer geometry specifications of the final strip can be reached. For this purpose, offline simulation tools are used for hot rolling as well as cold rolling. An accurate prediction of the deformation resistance and interstand softening behaviour of the new steel grade is key in the determination of the dimensional window. Preferably, the deformation resistance model is validated with experimental data, for example from tensile tests or laboratory mini-mills. Rolling simulations are performed, using prescribed process conditions with respect to for example load distributions, temperature and rolling speed requirements. The dimensional windows of respectively the hot strip mill and the cold strip mill are merged, resulting in a final product dimensional window, indicating the maximum strip width at a final, customer specified, strip thickness.

Published: December 2023

The Harmonic Structure (HS) is a recently introduced concept that paves the way for engineering metallic materials to achieve superior mechanical performance. They consist of soft, coarse-grained regions surrounded in three dimensions by an interconnected network of hard, ultra-fine grained regions. In addition, from a structural materials point of view, high entropy alloys have attracted attention due to their unique mechanical properties. In the present study, the HS design was applied to a high entropy CrMnFeCoNi alloy (also called "Cantor alloy"). The HS-designed Cantor alloy was successfully fabricated by mechanical milling, which is one of the surface severe plastic deformation processes, and the subsequent sintering process. The mechanical properties of these HS and homogeneous (Homo) Cantor alloy compacts were investigated by high-temperature compression tests in the temperature range of room temperature (RT) and 1173K, under initial strain rates of 0.01 s-1, 0.001 s-1, and 0.0001 s-1. The stress-strain curves of the HS compacts showed a large initial increase in stress and then a rapid decrease with strain, while that of the Homo compact showed a gentle increase and a gradual decrease. EBSD observation of the deformed compacts revealed that the HS compacts were probably deformed not only by dynamic recrystallization, but also by grain boundary sliding during deformation. The strain rate sensitivity value m of the HS compacts was 0.541 (true strain: 0.2) at 1173 K. In other words, the HS compacts exhibited pseudo-superplastic deformation at these temperatures.
Relation between Process Parameters and Pressure during Friction Stir Forming in the Development of a Superplastic Composite Steel Sheets
Authors: Tabatabaei Hamed Mofidi , Ohashi Takahiro , Nishihara Tadashi
Published: December 2023

In previous research conducted by the authors, a new vibration-damping steel sheet was developed using a new method employing friction stir forming (FSF) to create a laminated composite sheet in which steel sheets and superplastic alloys are laminated in layers. However, the details of the bonding mechanism have not yet been clarified. The present study investigates the relationship between the pressure during the process and the weld interface in the creation of the mentioned superplastic composite sheet. More specifically, a 0.5mm thick perforated steel plate is inserted between two Zn-22Al superplastic alloys and the FSF is applied to the top layer of Zn-22Al. The probe of the FSF tool passes directly above the perforated steel plate, the material stirred by the probe plastically flows into the hole and is joined to the underlying Zn-22Al interface by superplastic diffusion bonding (SPF/DB). It was revealed that the process parameters (rotational speed and tool feed rate) must be perfectly adequate to produce adequate heat input and pressure leading to a proper plastic flow of the material and the occurrence of superplasticity in Zn-22Al. In this study, as a first step to clarify the detailed joining mechanism, the amount of pressure applied to the specimen during the process is measured. While changing the process parameters, the pressure was measured at three points, under the probe of the friction stir process tool and, on the advancing, and retreating sides, to investigate the relationship between the parameters and the pressure at the joint interface.
A Unified Representation for Fundamental Equations of Various X-Ray Stress Measurement Methods
Authors: Ejiri Shoichi , Ohba Hiroaki , Sasaki Toshihiko
Published: December 2023

The X-ray stress measurements by the sin2ψ method, the cos α method and the XRD2 method are basically composed of the fundamental equations based on diffraction vectors and the calculation for determining X-ray stress. The fundamental equations are expressed differently, which are due to the fact that the measurement systems associated with the incident X-ray control device and the diffracted X-ray detector are different. Although the dependent variable that is the measured quantity is the same diffraction angle theta in the fundamental equations, the main independent variable is different like the tilt angle ψ in the sin2 ψ method and the central angle α, γ of the Debye-Scherrer ring in the cos α method, the XRD2 method, respectively. Therefore, the stress determination method has been devised based on each the fundamental equation. By clarifying the differences between each X-ray stress measurement method and making a relationship, a unified representation for the fundamental equations is formalized. Therefore, a comparison of each X-ray stress measurement method is expressed in the same Euler space, and a conversion method for each X-ray stress measurement method is presented.

Published: December 2023

Synchrotron X-rays have the advantage of being a micro beam, allowing us to create detailed stress maps. However, due to a dendritic structure, measuring the residual stresses of a welded part is difficult. This challenge is caused by the difference in the positions of the diffracted crystal grains. To address this problem, we proposed a double exposure method. In this presentation, the double exposure method was applied to measure the residual stress of the plate that was cut from the welded pipe. Detailed strain maps under a plane stress state were obtained. Conversely, the residual stress distributions of the welded pipe under a triaxial stress state were measured using neutrons. From these results, the detailed stress maps of the root part of the butt-welded pipe were made up by the complimentary use of the synchrotron X-rays and neutrons. The results can significantly explain theinitiation and propagation of stress-corrosion cracking. We name this analysis method the quantum beam hybrid stress analysis.
Preparation, Microstructure, and Mechanical Properties of Aluminum Matrix Composite by Accumulating Roll Bonding Method
Authors: Sasaki Gen , Liu Wen Chuang , Sugio Kenjiro
Published: December 2023

The ARB (Accumulative Roll Bonding) method is greatly watched as a new severe plastic deformation process that uses only a conventional general rolling machine. The ARB method is a preparation method of ultra-fine-grained, high-strength thin metal and alloy sheets by repeated rolling. The purpose of this study was to clarify the effectiveness of the ARB method as a metal matrix composite manufacturing process. At first, alumina particles and short carbon fibers were used as dispersoids, and pure aluminum was used as the thin plate. Then, the dispersoids were deposited on a pure aluminum plate to 2 vol.% dispersoids. Six of these aluminum sheets were stacked to form a multi-layer composite sheet, which was then cold rolled at a rolling reduction of 67%. After rolling, the sheet composites were cut in half, overlapped, and rolled again. The composites were obtained by repeating this process. When the repetition exceeded 6 times, the dispersoids tended to disperse in the aluminum matrix. In addition, uniform dispersion progressed through further repeat rolling. By repeated rolling, the tensile strength of the composite sheets was greatly improved. In addition, the tensile strength of the composites was higher than that of the ARB-processed monolithic aluminum sheet. The improvement in strength was caused by the refinement of aluminum grains rather than the particle dispersion.

Published: December 2023

Polyamide (PA) nanofibers (NFs) interleaves have been inserted as a continuous non-woven mat between prepreg plies of a carbon fiber reinforced (CFR) laminate during lamination. Hybridization has been made by mixing two different material scales, being the micro-scale and the nanoscale of the CFs and the NFs respectively and two different polymer types being thermosetting the matrix and thermoplastic the NFs. Final composite laminates have been produced by vacuum bagging and autoclave molding according to the consolidated industrial procedure of aeronautic parts. Traditional square CFR laminates with 20 plies have been also manufactured using the same unidirectional (UD) CFR prepreg tape with 0/90 stacking sequence for comparison. Rectangular specimens were finally extracted from the manufactured plates. Dynamic mechanical analysis (DMA) and three-point bending tests were carried out. The reduction of the glass transition temperature Tg revealed the achieved interaction among PANFs and the resin matrix. Moreover, bending strength increased up to 9% for hybrid laminates revealing that nanostructures can add functionalities to traditional composite laminates without affecting their mechanical performances.
High Temperature Deformation Behavior and Microstructure Evolution of Harmonic Structure Composites with WC-Co and High Speed Steel
Authors: Koiso Akiyoshi , Kuno Tomoko , Kawabata Mie , Ameyama Kei , Fujiwara Hiroshi
Published: December 2023

The high-temperature deformation behavior and microstructural changes of harmonic structure composites with WC-Co alloys and high-speed steel (HSS) were investigated in detail. A harmonic structure composite was fabricated by consolidating the mechanically milled powder having WC-Co and HSS powder. The harmonic structure composite demonstrates the microstructure composed of network area (WC-Co) and dispersed area (HSS). The harmonic structure composite shows a sufficient compressive strength in the compression tests at 773 K, but the compression strength decreases at temperatures of above 873 K. The 0.2% proof stress at high temperature almost unchanged even if the network area fraction changed. Furthermore, the network area plays an important role in the high temperature deformation of harmonic structure composites. These results suggest that the formation of voids for WC-Co boundary sliding and poor sintering is an important factor in stress reduction in the high-temperature compression of harmonic structure composites.

Authors: Sonam  , Mahapatra Arun Kumar , Shrikrishna Rajagopala
Published: December 2023

Psoriasis is an auto-immune, chronic, disfiguring skin condition that negatively impacts the quality of life of individuals. Its incidence rate among children has doubled since 1970, equally prevalent among males and females. Eka kushtha, one of the types of Kshudra kushtha (~minor skin diseases) can be correlated with psoriasis due to the resemblance in symptoms. A male child aged 12 years presented with symptoms of round, red, scaly, dry, silvery lesions over the extensor surface of bilateral upper and lower limbs for the last two years. Eka kushtha (~plaque psoriasis) of moderate severity was diagnosed on the basis of variable scaly plaques with marked erythema, scaling, and induration. Shodhana chikitsa (~bio-cleansing therapy) through Virechana karma (~therapeutic purgation) followed by Shamana chikitsa (~palliative therapy) as mentioned in Ayurveda classics were followed. Improvement in the clinical symptoms as well as changes in the scores of the Psoriasis Area and Severity Index and Children's Dermatology Life Quality Index scale was observed. The presently available treatment principles for psoriasis are based on controlling the symptoms and are associated with serious side effects. Encouraging results noticed in this case report give insight that Shodhana along with Shamana chikitsa is safe and effective in managing psoriasis in the pediatric age group.

Published: December 2023

The incidence of burns is higher in children than in adults. There is a wide spectrum in patterns of injury and severity. Most pediatric burns are small and can be managed in nonspecialist centers. Scald injuries occur due to the destruction of tissues by hot liquids, and tend to be the most common type of thermal injury under the age of five years, accounting for over 65% of the cases. Ayurveda describes burn injury as Agnidagdha vrana. This case report shows a four-year-old child, who sustained an accidental second-degree burn. The family members of the child extended good cooperation, during the treatment period. Irrigation of the wound with Triphala kwatha followed by topical application of Shatadhauta ghrita for first five days. Subsequently, irrigation of the wound with Triphala kwatha followed by topical application of Mahatiktaka ghrita was used until the 18th day. The wound healing was satisfactory. No secondary complications developed.

One of the supporting tools for Socata TBM 700 aircraft maintenance is the trestle, this tool is responsible for helping various aircraft checking processes such as jacking, leveling, and lifting. As a supporting tool, the hangar of the Politeknik Penerbangan Surabaya already has these tools. More specifically, the tool available is a hydraulic jack. This tool has the primary function of supporting the jacking process. However, the jacking tool owned by the Politeknik Penerbangan Surabaya is considered less effective and efficient in operation and safety, so creating a new tool with a more qualified level of efficiency and effectiveness is necessary. The new variant of the supporting tool is called the C17 trestle. The method used in this work is an experimental method that starts by designing a tool from a bottle Jack made from high-carbon steel. The primary purpose of this study is to determine the efficiency of the C17 trestle time working and safety during the maintenance process and practice by cadets. The results of this study show that the C17 trestle can be operated manually by a minimum of two people with an average time of 2 minutes 32 seconds and increases the percentage of work security and safety when the tool is used. This shows that the C17 trestle design is more suitable for use during the jacking process on the Socata TBM 700 aircraft

In order to have common general standards in language (English) for maritime there must be regulation regarding the standardization itself. The requirements for communicative competence of seafarers in STCW present a great challenge to Indonesian seafarers who will struggle to improve their linguistic competences, since in Indonesia English is still known as a foreign language. The research taken place at Merchant Marine Polytechnic of Sulawesi Utara with population of the sample is cadets in Ship Engineering study program. The research aims to evaluate the current Maritime English course curriculum in Indonesian shipping or maritime vocational colleges-universities by analysing communication skills required by seafarers on fishing vessels. Data was gathered from documents and interviews with industry participants. The results indicate that the current exam is inadequate in preparing students for global seafarer standards. The study suggests a genrebased approach for English language courses, including Maritime English (ESP), to enhance cross-cultural knowledge and improve work skills. This approach can help university graduates gain a competitive edge in the labor market by improving communication and work performance.

Online shopping is now popular due to the development of Internet technology that enables shoppers to shop anywhere, anytime. However, behind its convenience, some drawbacks can be detrimental for the users, such as the breadth of the market and variants of similar products offered by different online stores that cause more difficult evaluations for many shoppers. In such a situation, shoppers rely on a shortcut mechanism to make purchase decisions, which considers mainly other customers' ratings and reviews. This study aims to investigate that shortcut in Tokopedia. Therefore, the authors recruited judgmentally 120 shoppers as respondents. Data analysis using multiple linear regression reveals that online customer reviews and ratings significantly and positively influence purchase decisions.
