Authors: Peikert Mona L. , Inhestern Laura , Krauth Konstantin A. , Bergelt Corinna 
Published: April 2021

Zusammenfassung
Ziele der Studie Eine Krebserkrankung im Kindesalter geht häufig mit körperlichen sowie psychosozialen Belastungen einher, die über die Behandlung hinaus bestehen können. Die familienorientierte Rehabilitation (FOR) adressiert Behandlungsfolgen und unterstützt Familien bei der Rückkehr in den Alltag. Ziele dieser Studie waren es, Reha-Ziele und Zielerreichung in der FOR abzubilden, den Zusammenhang von körperlicher Leistungsfähigkeit und körperlichem Wohlbefinden zu analysieren und Prädiktoren der Veränderung der körperlichen Leistungsfähigkeit im Verlauf der FOR zu untersuchen.
Methodik Im Rahmen einer prospektiven Beobachtungsstudie wurden ärztliche Angaben zu Reha-Zielen, Zielerreichung und körperlicher Leistungsfähigkeit bei 175 Kindern (<18 Jahre bei Diagnosestellung einer Leukämie oder eines Tumors des zentralen Nervensystems) zu Beginn und am Ende der FOR analysiert. Das körperliche Wohlbefinden der Kinder wurde aus Eltern- und Patientensicht eingeschätzt. Der Zusammenhang von körperlicher Leistungsfähigkeit und körperlichem Wohlbefinden wurde mithilfe von Korrelationskoeffizienten analysiert. Mittels einer multiplen Regressionsanalyse wurden Prädiktoren der Veränderung der körperlichen Leistungsfähigkeit untersucht.
Ergebnisse Die am häufigsten definierten Reha-Ziele sind die Steigerung der körperlichen Leistungsfähigkeit sowie die Integration in die Gleichaltrigengruppe. Insgesamt werden die Ziele bei 82 bis 100% der Kinder erreicht und die körperliche Leistungsfähigkeit erhöht sich signifikant im Verlauf der FOR. Ein signifikant positiver Zusammenhang besteht zwischen der ärztlichen Einschätzung der körperlichen Leistungsfähigkeit und der elterlichen Einschätzung des körperlichen Wohlbefindens zu Beginn der FOR. Ein weibliches Geschlecht des Patientenkindes sowie eine längere Zeit seit der Diagnosestellung sind mit einer geringeren Veränderung der körperlichen Leistungsfähigkeit assoziiert und ein höheres Ausmaß der körperlichen Folgeschäden geht mit einer größeren Veränderung einher.
Schlussfolgerung Das 4-wöchige multimodale Programm der FOR adressiert verschiedene körperliche und psychosoziale Einschränkungen und geht unter anderem einher mit einer deutlichen Verbesserung der körperlichen Leistungsfähigkeit der Kinder. Die Veränderung der körperlichen Leistungsfähigkeit hängt mit verschiedenen soziodemografischen und medizinischen Faktoren zusammen (u.a. Geschlecht). Die Betrachtung dieser Einflussfaktoren könnte zu einer Optimierung der FOR beitragen.
Venous Thromboembolism in Trauma: The Role of Anticoagulation and Inferior Vena Cava Filters
Authors: Xiao Nicholas , Desai Kush R. 
Published: April 2021

AbstractVenous thromboembolism (VTE) is a significant contributor to morbidity and mortality among patients with severe trauma. Historically, prophylactic inferior vena cava filters (IVCFs) were used in high-risk trauma patients with suspected risk factors for VTE, including prolonged immobilization, and concurrent contraindication to anticoagulation. Mounting data regarding the efficacy of IVCF in this cohort, as well as concerns regarding morbidity of an in situ IVCF, have challenged this practice paradigm. In this review, we discuss the comanagement of VTE and trauma, including anticoagulation and the use of IVCF.

Published: April 2021

AbstractMajor pelvic fractures result from high-energy trauma including traffic accidents and falls, which usually leads to multiple injuries complicating the patient's management. Management of these patients requires a coordinated multidisciplinary approach. Transcatheter embolization is a minimally invasive and effective technique to control massive hemorrhage and can be performed using a variety of embolic agents. It has become an accepted first-line management option for retroperitoneal bleeds in many centers. In this article, the indications for endovascular management of hemorrhage from pelvic trauma, the various embolization techniques, and potential complications will be discussed.

Magnetic, morphological, and physical properties of Pr0.63La0.37−xSrxMnO3 (xSr = 0.00, 0.05, 0.10, 0.15, 0.20, and 0.30) magnetic nanoparticles have been studied experimentally based on the evolution of the amount of Sr in these systems and by heat treatment. A solid-state reaction method was used to prepare the samples. The microstructure of the samples was determined by scanning electron microscopy. Three sets of Sr-doped manganites of the perovskite family Pr0.63La0.37−xSrxMnO3 nanoparticles were heated at three different temperatures, i.e., 500, 700, and 800 °C. X-ray data showed that all compounds in the cubic space group Fd-3m crystallized. Field-cooled and zero-field-cooled thermomagnetic curves measured at low field and low temperatures showed that systems have different magnetic states, varying from superparamagnetic, ferromagnetic to paramagnetic states, with charge ordering behavior present in some prepared systems. The maximum entropy change of the xSr-800°C = 0.05 sample reached the highest value of refrigerant capacity compared to other systems in a magnetic field with 17.278 J/kg at 1 T and 208.264 J/kg at 7 T.

166.6-MHz superconducting cavities have been chosen for the High Energy Photon Source (HEPS) as the main accelerating structures to provide 900 kW of beam power and 5.4 MV of accelerating voltage. A proof-of-principle cavity adopting the quarter-wave beta = 1 geometry was previously developed. Excellent performance was achieved in vertical tests at cryogenic temperatures. The cavity was later welded with a helium jacket, dressed with a power coupler and other ancillaries, and high-power tested in a test cryomodule. Performance degradation was observed and analyzed. Evidence from temperature sensor readout and heat loss measurement results suggested an overheating in the cavity–coupler interface region causing a “thermal runaway” and eventually quenching the cavity at its design voltage. Electromagnetic-fluid-thermal coupled simulation has thus been conducted, and the hypothesis was nicely validated. Finally, solutions were proposed including an elongated niobium extension tube at the coupler port and an optimized helium gas cooling of the power coupler’s outer conductor. These modifications have been subsequently applied on the 166.6-MHz higher-order-mode damped superconducting cavities for the HEPS. Heat loss at 4.2 K contributed by the power coupler can be largely reduced with a modest gas cooling scheme. Similar design approaches can also be applied to other non-elliptical superconducting structures with on-cavity high-power coupler mountings.

Published: April 2021

To realize multi-band mode conversion in a high-power microwave incoherent power combination system, a tri-band conversion system (at X-, Ku-, and Ka-bands) is proposed in this paper. The tri-band conversion system mainly consists of three parts: a dual-band multiplexer, a circular waveguide with a 90° bend, and a tri-band mode converter. To investigate the mode coupling characteristics in the system, every part is carefully analyzed and verified. Numerical and simulation results show that the final conversion efficiencies of the conversion system are 98.9% [coaxial transverse electromagnetic (TEM) mode–coaxial TE11 mode at 10.16 GHz], 99.1% (coaxial TEM mode–coaxial TE11 mode at 14.45 GHz), and 99.6% (circular TM01–circular TE11 at 30.5 GHz). Meanwhile, its maximum power handling capacities reached 1.5 GW, 957.6 MW, and 726.2 MW. The good agreement between theoretical analyses and simulation results demonstrates that the proposed tri-band system is feasible in high-power microwave applications.

Published: April 2021

Abstract
Waste plastic bottle can be a pollutant that can damage the environment. If this waste plastic bottle is not well controlled, it will certainly harm the sustainability of other ecosystems. Usually, waste plastic bottle is difficult to decompose naturally, and even if it will be decomposed, it will take a long time, from 100 to 500 years. The main source of waste plastic bottle is usually the use of plastic material itself, which it is used to inseparable support in everyday life. In general, the use of plastic material has several considerations such as: lightweight, corrosion resistance, non-toxicity, friction and impact resistance, chemical resistance, good thermal stability, and good insulation properties. The general form of this product is disposable plastic bottles in drinking water. Waste plastic bottles are usually used for disposables product. Referring to this condition, they can assume and increase over a certain period the number of waste plastic bottles, where as plastic bottles are the largest source of pollutants on earth. To control this condition, it is necessary to develop a sustainable mechanism of press machine for flatting the waste plastic bottle into sheet plastic before being crushed and recycled into other products. Based on the observation of test results, it was found that the design of press machine for waste plastic bottle works with electric motor well, before being reprocessed.

Machining is done with and without cutting oil by using automatic feed lathe machine by varying the speed and depth of cuts to find out the cutting forces, cutting tool temperatures and surface roughness and found that these values are gradually increased in many cases. Also done microbiological check and found that the colony count is gradually increased from fresh oil usage to used cutting oil after machining. These tests also done on MMCs, pure brass and pure aluminum and compared the results with MMCs. Novelty focused in present research work is regarding Microbial Organism Growth and its pattern over a period of time since these organism are cancerogenic for the operator and in health and hygiene point of view, lot of research work is going on over this organism growth on combination of several cutting fluids and materials. With the evolvement of composite materials, effect of cutting fluids on the above phenomenon is focused in present work. As a routine work, effect of cutting forces also established by changing machining parameters and presented.

Abstract
SS316 and SS304 are most widely used materials in mechanical engineering. Many times the products are subjected to tensile load during work. The knowledge of tensile properties is essential for the mechanical engineer working with materials. SS304 and SS316 samples were fabricated using Direct Metal Laser Sintering (DMLS) as per JIS standards in different orientations. The samples were then tested for their tensile strength. The same has been simulated on the NX platform for prediction of variations in the tensile strength with change in orientation. The results obtained from the simulation are observed to be in good agreement with the experiment results when the process parameters are same in both the cases. Further, the simulation has been used to predict the tensile strength of the samples that were not experimented.

Published: April 2021

Abstract
A flood is an overflow of water that submerges land which is usually dry. Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel, particularly at bends or meanders in the waterway. This results in causing damage to human and property if they are in the natural flood plains of rivers or settled on the banks of rivers. To facilitate the appropriate measures for effective flood mitigation in advance, there is a need to model the flood plain which facilitates to locate the flood plain and its extent for effective flood mitigation measures. By understanding the extent of flooding and floodwater inundation, decision makers are able to make choices about how to best allocate resources to prepare for emergencies and to generally improve the quality of life. This research presents a straightforward approach for processing output of the HEC-RAS hydraulic model, to enable two and three dimensional floodplain mapping and analysis in the ArcView geographic information system. The methodology is applied to a stretch of river Krishna from downstream of Nagarjuna Sagar project to Kummaripalem which is located on upstream of Prakasam Barrage. The flood plain maps are developed for the flows corresponding to 2, 10, 25, 50 and 100 year return periods. The resulting surface model provides a good representation of the general landscape and contains additional detail within the stream channel. Overall, the results of the research indicate that GIS is an effective environment for floodplain mapping and analysis.

Published: April 2021

Abstract
The stability of structures mainly depends on the structural components like beams, columns and slab. Here in this study columns are reduced in the large open areas to access the whole room, which can be done by using the ribbed slab, grid slab and flat slab, which will help in minimizing the no. of columns which are required in the structure. A comparative study on seismic behaviour of G+6 school building is done with conventional slab and ribbed slab at seismic zone III and medium soil conditions by using SAP2000 software, it is found that in gravity analysis the maximum bending moments and shear force obtained for normal slab structure are 84.96 kN-m and 80.86 kN respectively, whereas for ribbed slab structure is 137.39 kN-m and 108.01 kN. The maximum storey stiffness of the ribbed slab structure is found to be 0.94 times of maximum storey stiffness of normal slab structure. It is found that the ribbed slab structure doesn’t perform well in moderate to high seismic areas. The stability of the ribbed slab structure can be enhanced by retrofitting the existing structure.

Published: April 2021

Abstract
There is a great demand for the concrete, the second largest consumed material and concrete making materials, for constructions due to stimulated growth of infrastructure worldwide. This lead to the scarcity of natural resources, resulting in creating vast interest in the research area to look for alternative materials which could satisfy both strength and performance criteria of concrete constructions. Pond ash, a waste product of thermal power plants, is one such material, that can be adopted as a suitable material as a fine aggregate in concrete, replacing natural sand partially or fully. Encouraging the usage of such a waste material as constituent in concrete so as to address the issues related to its disposal, environmental and ecological problems, is a social responsibility of researchers, thus contributing to 3Rs-Reduce Reuse and Recycle, there by promoting sustainable construction. It is commonly thought that as inert filter, fine aggregate has a very little effect on the finished concrete properties. However fine aggregate (natural sand or alternative material) and its characteristics play a substantial role in controlling the workability, strength, and durability of concrete constructions. Thus its detailed characterization is essential to boost the confidence of user. So in this report behavior of pond ash is studied. Change in compressive strength and slump values are studied.
1. Thirty six concrete matrices were designed with 0, 10, 20, 30, 40 and 100 percent pond ash by replacing fine aggregate.
2. The concretes of M20 with 0 percent pond ash and 100 percent fine aggregate shows compressive strength at 28 days curing 89.51 percent higher than conventional comparison mixes respectively.
3. The slump values got on decreasing from 50mm for 0 percent pond ash to 0mm for 100 percent pond ash.

AbstractA brief comprehensive overview is provided of the elements constituting the burden of kidney disease [chronic kidney disease (CKD) and acute kidney injury]. This publication can be used for advocacy, emphasizing the importance and urgency of reducing this heavy and rapidly growing burden. Kidney diseases contribute to significant physical limitations, loss of quality of life, emotional and cognitive disorders, social isolation and premature death. CKD affects close to 100 million Europeans, with 300 million being at risk, and is projected to become the fifth cause of worldwide death by 2040. Kidney disease also imposes financial burdens, given the costs of accessing healthcare and inability to work. The extrapolated annual cost of all CKD is at least as high as that for cancer or diabetes. In addition, dialysis treatment of kidney diseases imposes environmental burdens by necessitating high energy and water consumption and producing plastic waste. Acute kidney injury is associated with further increases in global morbidity, mortality and economic burden. Yet investment in research for treatment of kidney disease lags behind that of other diseases. This publication is a call for European investment in research for kidney health. The innovations generated should mirror the successful European Union actions against cancer over the last 30 years. It is also a plea to nephrology professionals, patients and their families, caregivers and kidney health advocacy organizations to draw, during the Decade of the Kidney (2020–30), the attention of authorities to realize changes in understanding, research and treatment of kidney disease.
Social Isolation and Loneliness Before and During the COVID-19 Pandemic: A Longitudinal Study of U.S. Adults Older Than 50
Authors: Peng Siyun , Roth Adam R 
Published: April 2021

Abstract

Objectives
The potential impact of social distancing policies during the coronavirus disease 2019 (COVID-19) pandemic on social isolation and loneliness is of increasing global concern. Although many studies focus primarily on loneliness, patterns of social isolation—particularly physical and digital isolation—are understudied. We examined changes in social isolation, physical isolation, digital isolation, and loneliness in U.S. adults older than 50 before and during the lockdown.

Methods
Two waves of the Health and Retirement Study, a national panel sample of U.S. adults older than 50 years, were used. Fixed-effects regression models were fitted to identify within-person change from 2016 to 2020 to examine the impact of social distancing policies during the pandemic.

Results
There was an increase in physical isolation and social isolation among respondents during the COVID-19 social distancing policies. However, respondents experienced no change in digital isolation or loneliness. The increase in physical isolation was only present for people with high COVID-19 concern, whereas people with low concern experienced no change in physical isolation.

Discussion
Despite an increase in physical isolation due to the social distancing policies, U.S. adults aged older than 50 stayed connected through digital contact and were resilient in protecting themselves from loneliness.
Incorporating vertical distribution in index standardization accounts for spatiotemporal availability to acoustic and bottom trawl gear for semi-pelagic species

Published: April 2021

AbstractAbundance indices from scientific surveys are key stock assessment inputs, but when the availability of fish varies in space and time, the estimated indices and associated uncertainties do not accurately reflect changes in population abundance. For example, indices for many semi-pelagic species rely on acoustic and bottom trawl gear that differ in water column coverage, and so spatiotemporal trends in fish vertical distribution affect the availability of fish to each gear type. The gears together cover the whole water column, and so in principle allow estimation of more accurate, combined indices of the whole population. Here, we extend previous methods and develop a vertically integrated index, which accounts for spatiotemporal correlation and works with data unbalanced spatially or unpaired from distinct surveys. Using eastern Bering Sea walleye pollock (Gadus chalcogrammus) as an example, we identified clear spatial and temporal patterns in vertical distribution and gear availability from 2007 to 2018. Estimated acoustic annual vertical availability ranged from 0.339 to 0.888 among years, and from 0.588 to 0.911 for the bottom trawl survey. Our results highlight the importance of accounting for the spatiotemporal and vertical distribution of semi-pelagic fish to estimate more accurate indices, and provide important context for gear availability.
