Abstract
Purpose On a global scale the main focus of traumatological therapy lies in the treatment of unintentional injuries or victims of violence. People of all ages and through all economic groups can be affected. Due to demographic change in Western industrial countries, however, this focus increasingly shifts towards fragility fractures. In Europe osteoporosis is the most common bone disease in advanced age. Secondary prevention programs like the Fracture Liaison Service (FLS) are becoming increasingly prevalent, especially in Anglo-American health care systems. In German orthopedic and trauma wards and hospitals, however, the FLS is still relatively uncommon. This article will examine the question whether secondary prevention programs like FLS need to be established in the German health care system. This study aims at finding out, whether in the area of a medium sized German city there is a difference regarding the initiation of osteoporosis diagnosis and therapy
between the regular aftercare by the general practitioner or the orthopedic surgeon and the aftercare by a specialist trained in osteology (Osteologe).
Materials and Methods For the open, randomized prospective study 70 patients with low energy fractures were recruited, who were older than 60 years and have been treated in our department.
Results 58 out of 70 patients have completed the study, which amounts to a follow-up of 82.9%. Limited mobility and a high degree of organizational effort were the main reasons for early termination of the study. While in the group with regular aftercare, only 2 out of 29 patients received a specific osteoporosis treatment, in group who were directly transferred to a specialist trained in osteology 17 out of 29 patients received specific treatment. After re-evaluation of group with regular aftercare in 21 out of 29 cases a specific osteoporosis treatment was recommended.
Conclusions It could be established that there is a significant diagnosis and treatment gap regarding the aftercare of patients with fractures caused by osteoporosis between general practitioners or orthopedic surgeons on the one hand and the specialists trained in osteology on the other hand. To improve the aftercare of fracture patients, cross sectoral networks with a background in geriatrics and orthopedic-trauma surgery like a FLS need to be established in the German healthcare system.

Published: May 2020

Abstract
Introduction Anterior knee pain (AKP) is one of the most frequent reasons for physical therapy consultations, remaining a difficult treatment challenge for professionals. The aim of this study was to evaluate the effects of an intervention using ultrasound-guided percutaneous neuromodulation (US-guided PNM) applied to the femoral nerve on pain and knee flexion range of motion (ROM), in patients with unilateral chronic anterior knee pain.
Methods Eight patients received a single intervention of NMP-e on the femoral nerve of the symptomatic knee. The level of pain and ROM were measured before, immediately after and 24 hours after the intervention.
Results A decrease in pain and an increase of ROM were observed after the intervention and at 24 hours. For pain values, a medium effect size was observed (ES = 0.63 ± 0.43) after the intervention, and a large effect size (ES = 1.73 ± 0.44) was found at 24h. Concerning ROM, the effect size was large at both moments (ES = − 1.30 ± 1.14; −1.76 ± 0.80, respectively).
Conclusion A single intervention of US-guided PNM on the femoral nerve produces a decrease of pain and increases the ROM, which is greater 24h after the stimulation.
Level of Evidence Level II-3.

Reactions that form C–C bonds are at the heart of many important transformations, both in industry and in academia. From the myriad of catalytic approaches to achieve such transformations, those relying on C–H functionalization are gaining increasing interest due to their inherent sustainable nature. In this short review, we showcase the most recent advances in the field of C–C bond formation via C–H functionalization, but focusing only on those methodologies relying on copper catalysts. This coinage metal has gained increased popularity in recent years, not only because it is cheaper and more abundant than precious metals, but also thanks to its rich and versatile chemistry.1 Introduction2 Cross-Dehydrogenative Coupling under Thermal Conditions2.1 C(sp3)–C(sp3) Bond Formation2.2 C(sp3)–C(sp2) Bond Formation2.3 C(sp2)–C(sp2) Bond Formation2.4 C(sp3)–C(sp) Bond Formation3 Cross-Dehydrogenative Coupling under Photochemical Conditions3.1 C(sp3)–C(sp3) Bond Formation3.2 C(sp3)–C(sp2) and C(sp3)–C(sp) Bond Formation4 Conclusion and Perspective

AbstractFor anterior cruciate ligament (ACL)-deficient patients, using a single bone-patellar tendon-bone (BPTB) graft for the double-bundle concept is one of the suitable approaches for acquiring better stability and reducing bone tunnel enlargement compared with the use of hamstring grafts. At least 10-mm width of BPTB autograft is needed to achieve this concept; however, it is larger than one-third of the patellar tendon width for small or middle physique patients. This study aimed to assess the clinical and radiographic outcomes of BPTB and gracilis (G) composite autografts for primary double-bundle ACL reconstruction in Asian athletes. Thirty-two Asian patients undergoing double-bundle ACL reconstruction with 7.0 to 7.5 mm of BPTB and 5.0 to 5.5 mm of G composite grafts were compared with 43 double-bundle ACL reconstruction with hamstring graft cases. The BPTB graft was used for the anteromedial bundle (AMB), with the G graft for the posterolateral bundle (PLB). Percentage of femoral bone tunnel enlargement compared with the original size was determined by computed digital radiographs on the first postoperative day and at 12 months in the anteroposterior (AP) and lateral views. Standard clinical evaluations, including the limb symmetry index (LSI), were also performed. Less PLB tunnel enlargement was found in the BPTB + G group than in the hamstring group in the AP (101.9 ± 22.9 vs.113.7 ± 20.6%, p = 0.031) and lateral views (104.4 ± 18.1 vs. 120.6 ± 23.4%, p < 0.01).There was no significant difference between the groups in 12-month postoperative clinical outcomes (Lysholm's score, Tegner's activity level scale, and International Knee Documentation Committee subjective knee evaluation score).The side-to-side difference was significantly less in the BPTB + G group (0.2 ± 1.3 vs. 0.9 ± 1.1 mm, p = 0.026). Despite the small sizes of the BPTB and G grafts, there was no significant difference in the knee extensor LSI between the groups (92.9 ± 10.1 vs. 93.3 ± 12.2%, p = 0.707), whereas the knee flexor LSI was significantly higher in the BPTB + G group (97.7 ± 14.8 vs. 90.1 ± 13.3%, p = 0.033). Double-bundle ACL reconstruction with a small size BPTB and G composite graft procedure provided good clinical outcomes and significantly less femoral bone tunnel enlargement than the hamstring procedure 12 months after surgery. It is thus a useful surgical option for ACL-deficient Asian athletes. This study reflects level of evidence III.

Abstract
For biomolecule sensing purposes a solid-state nanopore platform based on silicon has certain advantages as compared to nanopores on other substrates such as graphene, silicon nitride, silicon oxide etc Capitalizing on the developed CMOS technology, nanopores on silicon are scalable without any requirement for additional processing, the devices are low cost and the process can be repeatable with a high yield. One of the essential requirements in biomolecule sensing is the ability of the nanopore to interact with the analyte. In this work, we present a method for processing high aspect ratio, single nanopores in the range of 10–30 nm in diameter and approximately 700 nm in length on a silicon-on-insulator (SOI) wafer. The presented method of manufacturing the high aspect ratio individual nanopores combines optical lithography and anisotropic KOH etching with a final electrochemical etching step to form the nanopores and is repeatable and can be processed in batches. We demonstrate electrical detection of dsDNA translocation, where the characteristic time of the process is in the millisecond range. We also analyse the translocation parameters and correlate the enhanced length of the nanopore to a longer translocation time as compared to other substrates.

Abstract
Ferromagnetism in certain B2 ordered alloys such as Fe60Al40 can be switched on, and tuned, via antisite disordering of the atomic arrangement. The disordering is accompanied by a ∼1 % increase in the lattice parameter. Here we performed a systematic disordering of B2 Fe60Al40 thin films, and obtained correlations between the order parameter  (S), lattice parameter  (a
0), and the induced saturation magnetization  (M
s). As the lattice is gradually disordered, a critical point occurs at 1 − S = 0.6 and a
0 = 2.91 Å, where a sharp increase of the M
s is observed. DFT calculations suggest that below the critical point the system magnetically behaves as it would still be fully ordered, whereas above, it is largely the increase of a
0 in the disordered state that determines the M
s. The insights obtained here can be useful for achieving tailored magnetic properties in alloys through disordering.

Abstract

Reaktor Daya Eksperimental (RDE) is a 10MWt small modular of High Temperature Gas-cooled Reactor (HTGR) with passive safety features. This reactor has a Reactor Cavity Cooling System (RCCS) to evacuate heat loss through reactor vessel in operation condition and also the decay heat in the case of accident condition. One of the most important accidents to be considered is the Depresurized Loss Of Forced Cooling (DLOFC) for a long time period. During this accident, the reactor decay heat is evacuated to the cavity cooling system which is supposed in condition of totally loss its cooling water The analysis simulation was performed by solving numerically the two-dimensional equation of heat conduction. The implicit approach was used in the discretization of the equation, Matlab application program was used to execute the simulation program. The simulation was performed in two periods such as 1500 hours calculation to reach the steady state condition in normal operation and 500 hours of DLOFC period. Three conditions to be compared in this analysis: condition with water panel, condition without water panel, and condition without water panel but with high conductivity of concrete. The results show the increasing temperature of core after reactor shut-down until attaint the maximum temperature divers from 1048°C to 1080°C. According to reactor building, the peak temperature of internal concrete wall is 96°C in condition with water panel and rises to 141.6°C in condition without water panel. The temperature can be decreased to 94.3°C in increasing three times the concrete conductivity. In all conditions the reactor core remains safe because the peak temperature is still under the limit of 1600°C. Increasing the concrete conductivity is an alternative means to keep the concrete temperature under the limit of 100°C in accident condition.

Abstract
RDE is an experimental power reactor that designed base on HTGR technology. This reactor has an indirect cycle power conversion system with primary coolant is helium and it secondary is water. RDE uses pebble fuel and multi-pass refuelling scheme. Helium coolant was predicted to be contaminated with various of gas impurities such as CO2, H2O, O2, CH4, N2, and H2 and CO. Those impurities must be maintained at certain limits by using Helium Purification System (HPS). Carbon monoxide (CO) is difficult to separate from the helium due to its small molecular size. Firstly, in HPS CO must be converted to CO2 by using cupric oxide (CuO) in the CuO Column bed and then CO2 will be adsorbed by molecular sieve. The CuO column bed operation temperature has a significant contribution to CO oxidation results. The purpose of this research was to determine the influence of temperature to oxidation process on CuO bed. The ChemCAD computer code modelling and simulation was used as a method. CuO bed is simulated by kinetic reactor and activation energy of each reaction is set up. The inlet mass flow rate of helium to CuO bed is 10.5 kg/h, 30 bar of pressure and the temperature has been varied to get the optimum result of CO2. The simulation has shown that CuO bed optimum temperature for producing CO2 is 250°C. In the HPS, this temperature can be maintained by using heater that has been installed before CuO bed.

Abstract
The 10 MW Indonesia’s Experimental Power Reactor (RDE) is a High Temperature Gas Cooled Reactor (HTGR)-type and planned to be operational in the Puspiptek Serpong area in 2022/2023. The reactor applies helium gas coolants, graphite moderator and 17% 235U enrichment fuels and has 8 control fuel rods. To design a nuclear reactor, there are many safety aspects which should be taken into account and one of them is neutronic safety analysis dealing with an accident of reactivity core change due to increases of fuel and moderator temperatures. To begin with the safety analysis, the RDE core should be modeled utilizing the combination of nuclear data libraries and a computer code. Prior to estimate the reactivity core change in the RDE core, the calculation of neutron effective multiplication factors during the accident was accomplished using the MCNPX computer code. In this paper, the neutronic analysis of RDE core has been focused on how the fuel temperature increase implies the reactivity core change in the RDE reactor. By combining the three major world nuclear data libraries and the MCNPX code, the all calculated results showed that all core reactivity changes in the RDE core due to fuel temperature increases starting from 26.85 °C (300 K) to 2,726.85 °C (3,000 K) are all negatives except those in the reflector zone which principally accumulates generated neutrons always coming from the central of the core during reactor operation. Therefore, those do not affect at all the safety of the reactor core during the accident. Indeed, the RDE reactor core is totally safe in the event of fuel-temperature-increase during its reactor operation and hence the RDE reactor is in a steady, safe operation.

Abstract
The Generation IV nuclear power system has been developed by the Generation IV Forum (GIF) with its benefits such as highly economical, enhanced safety, low waste production, and proliferation resistant. MSR is one of Generation IV nuclear power system which uses molten salt as a fuel and a coolant, therefore its technology differs from the conventional solid-fuel reactors. In this study, the author focus on the safety characteristic analysis of the MSRs, in which a point kinetic equations and core heat transfer have been modeled by developing a mathematical model for MSRs. The founded model is applied to analyze the safety characteristics of the molten salt actinide recycler and transmuter system (MOSART) by simulating transient basic condition, and that is the unprotected loss of flow (ULOF) and unprotected overcooling accident (UOC). The result of reactor accident simulation is power distribution and temperature in the core reactor toward the time and showing that MOSART conceptual design is a reactor design which is stablee inherently. This reseach purposes to give basic understanding about safety characteristic of the MSR.

Published: May 2020

Abstract
Pavement damage detection is indeed a very important process for the management of roads. Nowadays, scholars are focusing on finding a simple and accurate way to detect road cracks aiming to increase its life span and improve its safety and quality. However, due to some factors including cost of implementation and level of experiences required small communities and developing countries are yet unable to adapt this idea. Therefore, developing a feasible method is becoming extremely important for improving the quality and safety of pavements. Thus, this study is intended to propose a framework for pavement crack detection and classification through the use of inexpensive set of sensors and the applications of artificial neural networks. As part of the project, difficulties that are going to be faced by local agencies in small communities will be highlighted and possible solutions will be suggested. In general, this framework is expected to be helpful to government entities in developing plans and taking actions toward providing a suitable pavement distress mitigation strategy.
