Authors: Arshad Muhammad , Ullah Zahid , Khalid Muhammad , Ahmad Naveed , Khalid Waqar , Shahwar Duri , Cao Yue
Published: December 2018

A vehicular ad‐hoc network is an emerged technology, where vehicles communicate with one another and Road Side Units. Vehicular ad‐hoc networks are categorised as a sub‐branch of mobile ad‐hoc networks, and they help in enhancing traffic efficiency and safety. Vehicular ad‐hoc networks facilitate communication by dissemination of messages relaying through vehicles. However, malicious nodes can propagate false safety alert in a network due to its malicious behaviour or selfishness. False messages in vehicular ad‐hoc networks can change drivers behaviour and create a disastrous situation in the network. Therefore, it is more important to thwart these false messages. The article presents a beacon trust management system and fake data detection (BTMS‐FDD) scheme. The trust management system uses speed and density information to establish a relationship with vicinity vehicles. The false safety event detection scheme uses relative safety and beacon messages to detect false safety event more accurately. For false safety events, a scheme uses position and speed information of beacon and safety‐related messages. To analyse the performance of proposed detection scheme, it is compared with ELIDV and host IDS schemes. The simulation results demonstrate that proposed malicious data detection scheme is better in terms of true positive, false positive and overhead.

Authors: Xu Zhepu , Yang Qun
Published: December 2018

Safety assessment of the buffer section of maintenance work zone is crucial for the safety of maintenance staff and travelling vehicles. To make up for the limitations of current methods to do timely safety assessment, this study proposes a fast method based on naturalistic driving, automatic segmentation technology, and spatial clustering analysis. Firstly, collect vehicle behaviour data by naturalistic driving method; secondly, extract fragments in the data containing traffic conflict information using the automatic segmentation technology; thirdly, cluster these fragments by kernel density analysis to find the location of the high‐density point of traffic conflict (Otc); finally, calculate the stopping sight distance (SSD) that vehicles need to stop completely from Otc, measure the distance L ꞌ between Otc and the work area, and compare SSD, Lꞌ with the buffer section length L, then the safety of the buffer section of maintenance work zone can be assessed. Practice has proved that this novel method can collect the behaviour data of vehicles passing through quickly and flexibly, and do a timely safety assessment for the zone, thus can better meet the actual needs of maintenance.

Stochastic optimisation for investment analysis of flow battery storage systems
Authors: Tohidi Yaser , Gibescu Madeleine
Published: December 2018

In this study, a stochastic optimisation model is proposed to investigate revenue streams for flow batteries type of energy storage (ES) in a set‐up consisting of photovoltaic (PV) solar plant and load. Revenue streams investigated are (i) arbitrage in electricity markets between day‐ahead market (DAM) and imbalance market (IM) and (ii) self‐consumption of local PV production via storage for supplying the peak load. Stochastic parameters are represented by a set of scenarios and include DAM and IM prices of electricity, solar irradiation and load level. Scenarios are generated by analysing the historical data of the stochastic parameters. A stopping criterion based on the relative change of the revenue is proposed in order to reach a sufficient number of scenarios. The simulation is done on the Dutch DAM and IM electricity prices and for two residential and office load profiles with 107 kW average load and ∼30% PV production. The candidate flow batteries investigated are based on hydrogen‐bromine chemistry with different power and energy capacities. The results reveal the potential for a positive business case both for ES stand‐alone generation revenue just through arbitrage and also for ES added to PV‐load set‐up generation revenue through arbitrage and self‐consumption.

Authors: Park Kyu‐Hoon , Lee Ho‐Yun , Asif Mansoor , Lee Bang‐Wook
Published: December 2018

The black‐box arc model is known to be a useful technique to simulate dynamic arc‐circuit interaction by reflecting arc characteristics. Existing researches have shown that the black‐box model has been widely used to analyse the ac arc characteristics of SF6 and air circuit breakers. Due to the enormous energy and steep rise rate (di /dt) during dc fault, it is important to consider dc arc characteristics. However, there are no examples of black‐box models for dc circuit breakers utilised in railway systems and dc microgrid. In this study, the applicability of the black‐box model, which was applied to the existing ac arc analysis, was verified for the dc arc analysis. Black‐box modelling is applied to datasheet of industrial low‐voltage circuit breakers and parametric sweep method was used to select Schwarz model parameters considering the tendency of dc arc current waveform for the dc pole‐to‐pole fault. The authors also applied the Levenberg–Marquardt algorithm, which is the most extensively used for the optimisation of functional parameters, to the Schwarz model for accurate and reliable arc modelling. As a result, the dc arc feasibility of the black‐box model was analysed through simulation results, and a model optimisation technique was proposed.
Protection and post‐fault recovery of large HVDC networks using partitioning and fast‐acting DC breakers at strategic locations
Authors: Rahman Md Habibur , Li Rui , Yao Liangzhong , Xu Lie
Published: December 2018

DC fault protection arrangements for a large multi‐terminal HVDC (MTDC) network are proposed where fast‐acting DC circuit breakers are only used at strategic locations with the large DC network to be operated interconnected but partitioned into islanded DC zones in case of any DC fault events in one of the DC zones. Each DC network zone can be protected using low cost, slow protection devices such as AC circuit breakers (ACCBs) coordinated with DC switches or slow mechanical type DC circuit breakers. This ensures the maximum ‘ loss‐of‐infeed’ for any AC networks connected to the large HVDC system is kept within acceptable limits with reduced investment in protection cost as expensive fast‐acting DC circuit breakers are kept to a minimum. A post‐fault recovery method of the faulty section is proposed including the reconnection with the healthy part of the network to ensure reliable and smooth restoration of the large MTDC network. A detailed pre‐fault and post‐fault power flow analyses are also conducted in a MTDC network with DC voltage droop control. The proposed protection arrangements and post‐fault recovery method are validated by simulation of a two‐zone, six‐terminal DC network with respective radial and meshed configurations.

Published: December 2018

Curcumin is a natural active constituent with a great variety of beneficial biological and pharmacological activities, is a practically water‐insoluble component. The scope of the present work was to prepare a solid dispersion (SD) formulation to enhance the dissolution rate of curcumin. The SD was prepared using curcumin and β ‐cyclodextrin (CD)/HA via a classical ethanol‐based solvent evaporation method. The as‐prepared β ‐CD/HA and SDs were selectively characterised by various analytical techniques including X‐ray diffraction, transmission electron microscopy, scanning electron microscopy, specific surface area/pore size analysis, Fourier transform infrared spectroscopy, and high‐performance liquid chromatography. According to the dissolution tests, it was confirmed that β ‐CD/HA–curcumin SD can significantly enhance the dissolution of curcumin. In addition, an increasing trend was seen between the β ‐CD weight ratio and the dissolution rate of curcumin, and β ‐CD/HA–curcumin (9:1) SD was shown to be the best formulation among all tested samples with over 90% curcumin dissolved in 180 min. Besides, β ‐CD/HA–curcumin (9:1) SD exhibited pH and medium‐dependent curcumin release behaviours. The antioxidant activity of released curcumin showed no difference to original curcumin. These results clearly demonstrated β ‐CD/HA can be a promising SD carrier to improve the dissolution of curcumin.

Authors: Zhang Rui , Hu Yifeng , Chou Qingqian , Lai Tianshu , Zhu Xiaoqin
Published: December 2018

In this study, the amorphous‐to‐crystalline transitions of superlattice‐like (SLL) Zn15Sb85/Ga30Sb70 thin films were investigated by in situ film resistance measurement. The thermal stability, resistance and band gap of the SLL Zn15Sb85/Ga30Sb70 thin film perform well. The data retention temperature for 10 years increases from 177°C of [Zn15Sb85 7/Ga30Sb70 3] to 220°C of [Zn15Sb85 2/Ga30Sb70 8]. The X‐ray diffraction patterns show the presence of a large amount of Sb phase in the Zn15Sb85/Ga30Sb70 thin films, which causes a rapid phase transition. The surface morphology is observed by atomic force microscopy, which indicates that the thickness of Ga30Sb70 in the SLL thin films can affect the grain size and inhibit the crystallisation process. For the Zn15Sb85/Ga30Sb70 thin films, an ultra‐short switching time of around 2 ns is achieved. These results indicate that the SLL Zn15Sb85/Ga30Sb70 thin films have a promised application in phase change memory.

Published: December 2018

A facile morphological specific precipitation method by volumetric control of the precursors has been demonstrated to achieve tetrapod‐like and dodecahedron‐like Ag3PO4 microparticles, which show superior visible‐light responsive of photocatalytic activity when comparing to TiO2 (P25). This study also reveals that the tetrapod‐like Ag3PO4 microparticles exhibit significantly higher photocatalytic activity (95.6% degradation within 20 min, k: 0.1937 min−1) than the dodecahedrons (78.9% degradation within 30 min, k: 0.0593 min−1) for the degradation of rhodamine B (RhB, 10 ppm) under low‐power white light‐emitting diode irradiation (300 mW cm−2), which may be attributed to the high reactivity of {110} facets. Moreover, holes and superoxide radicals were the main reactive species involved in RhB degradation.
Salicylic acid‐sensitised titanium dioxide for photocatalytic degradation of fast green FCF under visible light irradiation
Authors: Tang Wei‐Renn , Wu Tsunghsueh , Lin Yang‐Wei
Published: December 2018

Synthesis and modification of salicylic acid (SA) adsorbed titanium dioxide (SA‐TiO2) was proposed through a sol–gel reaction following annealing treatment. The prepared SA‐TiO2 exhibited visible light absorption because of the formation of an intramolecular ligand to metal charge transfer transition. The photocatalytic activity of SA‐TiO2 for the degradation of fast green FCF under visible light irradiation was evaluated. The experimental results suggest that the enhanced photocatalytic activity of SA‐TiO2 is attributed to the visible light absorption ability. Moreover, •OH and •O2 − radicals are major active species involved in dye degradation. The practicality of SA‐TiO2 was validated through the degradation of various dyestuff in environmental water samples under visible light irradiation.
Analysis of the origin of water, carbon monoxide, and carbon dioxide in the Uranus atmosphere
Authors: Lara L. M. , Rodrigo R. , Moreno R. , Lampón M.
Published: December 2018

Context. We present here an analysis of the potential sources of oxygen species in the Uranus atmosphere.

Aims. Our aim is to explain the current measurements of H2O, CO, and CO2 in the Uranus atmosphere, which would allow us to constrain the influx of oxygen-bearing species and its origin in this planet.

Methods. We used a time-dependent photochemical model of the Uranus atmosphere to ascertain the origin of H2O, CO, and CO2. We thoroughly investigated the evolution of material delivered by a cometary impact, together with a combined source, i.e. cometary impact and a steady source of oxygen species from micrometeoroid ablation.

Results. We find that an impactor in the size range ~1.2–3.5 km hitting the planet between 450 and 822 yr ago could have delivered the CO currently seen in the Uranus stratosphere. Given the current set of observations, an oxygen-bearing species supply from ice grain ablation cannot be ruled out. Our study also indicates that a cometary impact cannot be the only source for rendering the observed abundances of H2O and CO2. The scenarios in which CO originates by a cometary impact and H2O and CO2 result from ice grain sublimation can explain both the space telescope and ground-based data for H2O, CO, and CO2. Similarly, a steady influx of water, carbon monoxide, and carbon dioxide, and a cometary impact delivering carbon monoxide give rise to abundances matching the observations. The time evolution of HCN also delivered by a cometary impact (as 1% of the CO in mass), when discarding chemical recycling of HCN once it is lost by photolysis and condensation, produces a very low stratospheric abundance which could be likely non-detectable. Consideration of N2-initiated chemistry could represent a source of HCN allowing for a likely observable stratospheric mixing ratio.

Conclusions. Our modelling strongly indicates that water in the Uranus atmosphere likely originates from micrometeroid ablation, whereas its cometary origin can be discarded with a very high level of confidence. Also, we cannot firmly constrain the origin of the detected carbon monoxide on Uranus as a cometary impact, ice grain ablation, or a combined source due to both processes can give rise to the atmospheric mixing ratio measured with the Herschel Space Observatory. To establish the origin of oxygen species in the Uranus atmosphere, observations have to allow the retrieval of vertical profiles or H2O, CO, and CO2. Measurements in narrow pressure ranges, i.e. basically one pressure level, can be reproduced by different models because it is not possible to break this degeneracy about these three oxygen species in the Uranian atmosphere.
Surface abundances of CNO in Galactic O-stars: a pilot study with FASTWIND
Authors: Carneiro L. P. , Puls J. , Hoffmann T. L. , Holgado G. , Simón-Díaz S.
Published: December 2018

Context. Rotational mixing is known to significantly affect the evolution of massive stars; however, we still lack a consensus regarding the various possible modeling approaches and mixing recipes describing this process. The empirical investigation of surface abundances of carbon, nitrogen, and oxygen (CNO) in large samples of O- and B-type stars will be essential for providing meaningful observational constraints on the different available stellar evolution models.

Aims. Setting up and testing adequate tools to perform CNO surface abundance determinations for large samples of O-type stars, by means of the fast performance, NLTE, unified model atmosphere code FASTWIND.

Methods. We have developed a set of semi-automatic tools for measuring and analyzing the observed equivalent widths of strategic optical C, N, and O lines from different ions. Our analysis strategy is based on a χ2 minimization of weighted differences between observed and synthetic equivalent widths, the latter computed from tailored model grids. We have paid special attention to the (significant) errors introduced by typical uncertainties in stellar parameters. In this pilot study, we describe these tools, and test their performance and reliability using a set of high quality spectra of a sample of 18 presumably single Galactic O-type stars with low projected rotational velocities (v sin i≲100 km s−1), and previously determined stellar parameters. In particular, we have compared the outcome of our analysis with results from existing studies and theoretical stellar evolution models.

Results. Most of our results for carbon and nitrogen agree, within the errors, with both theoretical expectations and literature values. While many cooler dwarfs display C and N abundances close to solar, some of the early- and mid-O dwarfs – and most supergiants – show significant enrichment in N and depletion in C. Our results for oxygen in late-O dwarfs are, however, unexpectedly low, possibly indicating deficiencies in the adopted oxygen model atom. For all other objects, no systematic problems in their oxygen content have been identified. Specific stars in our sample show peculiarities in their abundances, and we suggest hypotheses regarding their origin.

Conclusions. Our method is (almost) ready to be applied to large samples of late and mid O-type stars – although the oxygen model atom needs to be improved and carefully tested first. For early O-type stars (O4 and hotter), a simultaneous UV analysis seems to be inevitable, due to the scarcity and weakness of optical C and O lines. This will necessarily imply a more complex modeling, additionally accounting for the effects of X-rays from wind-embedded shocks and wind inhomogeneities.

Published: December 2018

In relation to the achievement of the target SDG’s No. 14, the sustainable shark fisheries management need to implement. As a part of the tuna fisheries by-catch, a high number of shark resources have been caught in the Indian Ocean waters. One of the main vessels of tuna catchers in the Southern Indian Ocean of Java is the tuna longline from Cilacap. This paper aims to analyze the shark by-catch of tuna longline in the Indian Ocean in the south Java that landed in Cilacap. The research data was obtained from daily recording activities of fishing vessel loading activities by Cilacap Ocean Fisheries Port staff during the period of 2013-2017. The analysis was done through data tabulation, graphical approaches, and data trend analysis through the availability of time series data. The data analyzed include fleet development, fishing ground, catch composition and CPUE value. The results of the analysis show that there are about eight species of sharks that are by-catch of tuna longline from Cilacap. The highest shark by-catch occurred in April with CPUE averaging 9 kg/day/vessel. The blue shark (Prionace glauca) is the dominant shark catch which reaches 66% of the total sharks catch.

Published: December 2018

In response to Japan’s increase on coal dependence, co-firing of woody biomass in a coal power plant has been considered as the most feasible sustainable alternative. We propose torrefaction as an effective method to improve the quality of biomass fuel. To measure how much CO2 can be avoided by utilizing torrefied fuel, Life Cycle CO2 (LCCO2) of woody biomass co-firing in the Japanese coal power plant was conducted in this study. As a comparative analysis in the LCCO2, scenarios constructed included the use of woody biomass in the form of chip, pellet, and torrefied fuel. Due to the unavailability of large quantity domestic feedstocks in Japan, Indonesia was chosen as the origin of the imported woody biomass in the simulated scenarios. The results showed that significant CO2 reduction could be achieved especially in the co-firing that includes torrefied fuel. In the case where 30cal% of torrefied fuel or 5cal% of pellets were used for co-firing in a 50 MW capacity coal power plant, 95,000 t of CO2 could be avoided annually compared to using 100% coal.

Published: December 2018

Every year, the total of plastic industry in Indonesia grows rapidly. Not only giving positive effects on economic, but industrial development also causing a negative impact on the environment. Those negative impacts are caused by inefficiently using of resources and industrial waste which could pollute the environment. Therefore, it is necessary to calculate the impact itself by using the Life Cycle Assessment (LCA) method. The LCA could help us to take better decision to improve the production process and products which could minimize the energy consumption and resources. PT XYZ is a plastic injection company. This company hasn't collected, calculated and analysed their products and production process which may contribute to environmental damage. Therefore, this study will collect the data about the potential environmental impact which caused by the product of PT XYZ. LCA was performed at plastic car battery container type "X" and type "Y" using IMPACT 2002+ method in SimaPro8 software. The result of data calculation showing that the potential environmental impact is more dominant in these categories: respiratory inorganics, non-renewable energy, and global warming. The component which caused the greatest potential for respiratory inorganics and global warming is coming from electrical energy consumption (lignite).

Published: December 2018

The amount of waste generated is ever-increasing due to population growth, however adequate waste management has never been a focus in everyday life. The action of the household as the beginning stage of waste management is also crucial. How households manage their waste is also influenced by their socio-economic characteristics. This study aims to investigate household characteristics that influence their waste management. This study employed the Indonesian Family Life Survey 2014 data using probit regression method. The result shows that location significantly affect waste management behaviour which households in urban areas hold higher probability to manage their waste compared to those in rural areas. The level of education and knowledge also have positive impact on household’s waste management. The level of income also positively affect waste management behaviour of households. Demographic variables such as age and gender are significant and indicate that women and older people have better waste management compared to men and younger people. These results support the hypothesis that household’s waste management behaviour is significantly influenced by their characteristics.

Sustainable approach to tempeh industrial wastewater management in Karawang
Authors: Puspawati Silvi Wahyu , Soesilo Tri Edhi Budhi
Published: December 2018

Tempeh is a traditional soybean product from Indonesia. It is a high-protein food whose cost per unit is cheaper than any other animal protein sources. However, processes undertaken by tempeh industries will produce waste. To produce tempeh needs a lot of water used for boiling, soaking, leaching, and peeling the soybeans. The problem is that tempeh industries have not undertaken wastewater management properly, which potentially causes the quality of tempeh industrial wastewater to exceed the prescribed quality standard, having negative impact on both the environment and the people living around those industries. This research aims to describe tempeh industrial wastewater management. It is mixed-methods research employing qualitative and quantitative methods, especially through literature review, observation, interviews, and laboratory analysis. Research findings show that the alternative waste management suitable for tempeh industries is to utilize wastewater by considering environmental, social, and economic aspects. Such utilization is carried out by making liquid organic fertilizer and biogas from a mixture of household organic waste. These research findings refer to SDGs’ agenda, especially the goal no. 6 (six), i.e. to improve water quality by reducing pollution from wastewater.

Children are important asset for a country’s future and development. Their health and well-being matter in determining their productivity in the future. However, obesity rates amongst children in Indonesia is on the rise. Ministry of Health in Indonesia reported the highest national prevalence of obesity occurred in children aged 5-12 years (18.8%), followed by groups 13-15 years (10.8 %), and 16-18 years (7.3%). Obesity itself is caused by increased intake of sugar and fat that are mostly found in prepared food and junk food as well as low physical activity. Accordingly, prepared food consumption is on the rise as well due to the modern fast-paced lives these days. Using data from Indonesian Family Life Survey wave 5, this paper aims to find association between family’s characteristics and children’s health status. The result shows economic class have no significant effect on children’s health status. On the other hand, mother’s years of schooling, mother’s health, fast food consumption and father’s smoking behaviour have a significant association on children’s health. The outcome of mother’s well-being give positive effect on children’s health since they are traditionally the caregiver of the family, hence with better well-being, they are able to create better environment for the children.
Does work influence women’s autonomy or does autonomy deliberate women to work?
Authors: Ristiana Ruskin , Handayani Dwini

Work, especially paid work, has been assumed to enhance women’s autonomy, particularly their household autonomy. However, this assumption does not work in one causal direction. The causality relationship works both ways, that women work due to their high level of autonomy, but also because their employment status will increase their autonomy. The aim of this study is to understand the relationship between women’s work status and their household autonomy. This study used data from the Indonesian Demography and Health Survey 2012, together with a multinomial logistic regression analysis on married women’s work status and autonomy as dependent and independent variables, respectively. It was found that work status influences married women’s household autonomy and vice versa. However, the direction and strength of the influence depend on the type of work status and autonomy.
Investigating the relationship between variation of greenhouse gases concentrations and humidex

The increasing greenhouse gases (GHGs) in the atmosphere contribute to increasing average temperature earth’s surface. This research investigated relationship between variation of GHGs and human thermal comfort based on humidity index (humidex). This study applied humidex, an indices to assess the thermal comfort. The analysis was done by examining the observational data from two different monitoring stations in Serpong and Bogor. The result showed that the average CO2 concentration per month ranged between 422 and 453 ppm in Serpong, whereas in Bogor the average CO2 concentration per month was 413-426 ppm. The average CH4 concentration per month variation in Serpong was 2.05-2.65 ppm. While in Bogor, the average CH4 concentration per month variation ranged between 1.92 and 2.08 ppm. The difference of GHGs concentration in each location might be influenced by meteorological parameters and environmental characteristics. The comfort level according to humidex in Serpong was 30.5-41.5 whereas in Bogor was 29.4-38.5. The correlation between GHGs concentration and air temperature in urban areas in both stations showed a significant and strong but negative relationship. The relationship between GHGs concentration and humidex was indirectly indicated by the relationship of GHGs concentration on air temperature as indicator of humidex.
Assessment of lobster resources management with ecosystem approach in Pangandaran Water
Authors: Samusamu Andrias S. , Lukijanto
Published: December 2018

The development of lobster production in pangandaran during the last decade (2006-2013) is in the range of 0.5 to 12 ton/year with an increasing trend in 2010-2013, but then increasingly decline since 2014. Pressure on lobster populations followed by a decrease in environmental carrying capacity may threaten the lobster's sustainability capacity to grow and develop naturally. This paper aims to analyze the reference values of the components required in the application of EAFM (Ecosystem Approach to Fisheries Management) to manage lobsters in Pangandaran. The six domains in EAFM include: a) resource domain, b) fishing techniques, c) habitat and ecosystem, d) economy, e) social, and f) institutional domain in general it will affect the sustainable management of lobsters in the Pangandaran. The method used in this research is AHP (Analytic Hierarchy Process). Research results show that the coral cover is an important aspect that cannot be separated from the management of lobster resources. Thus, the right management option is that both central and local governments need to reassure the effectiveness of the regulatory tools for the management of lobsters and conduct continuous and comprehensive lobster stock assessments while considering socioeconomic aspects in the context of sustainable lobster management in the Pangandaran.
Aktuelle Trends in der flexiblen Ureterorenoskopie – ein Update

Published: December 2018

Die flexible Ureterorenoskopie (fURS) kann als „urotechnologische“ Erfolgsgeschichte bezeichnet werden. Seit der Einführung der fURS in die Harnsteintherapie wurde diese immer weiter technisch verbessert, was zu exzellenten klinischen Ergebnissen bei niedrigen Komplikationsraten führte. In den letzten Jahren prägte insbesondere die Einweg-Ureterorenoskopie die Landschaft der urologischen Endoskopie. Bei genauerer Betrachtung ist diese Entwicklung jedoch keine genuine Innovation, sondern vielmehr eine weiterführende Optimierung, die primär zur Vereinfachung innerbetrieblicher Abläufe (keine Sterilisation, keine Reparaturen) sowie zur Verhinderung der Keimübertragung bei insuffizient aufbereiteten Arbeitskanälen führt. Neue Technologien wie eine automatisierte Laserlithotripsie, intrarenale Temperatur- und Druckmessung warten noch auf ihre Markteinführung und den Einsatz bei der fURS. Diese hätten das Potenzial die endoskopische Steintherapie einen weiteren entscheidenden Schritt voranzubringen.

Ziel Untersucht werden die Kooperationsbedingungen der beteiligten Akteure in einem Modellprojekt zur Koordination von SGB V- und XII-Leistungen.

Methode Interviews mit gemeindepsychiatrischen Akteuren aus der Modellregion und qualitativ-inhaltsanalytischer Auswertung.

Ergebnisse Ähnliche Steuerungsziele und Vergütungsmodelle sind Voraussetzungen rechtskreisübergreifender Zusammenarbeit. Gemeindeferne Versorgung sowie (infra-)strukturelle Defizite wirken sich hinderlich aus.

Schlussfolgerungen Die Implementierung sektorenübergreifender Finanzierung für Behandlungs- als auch Eingliederungsleistungen sind ein erster Schritt in Richtung rechtskreisübergreifender Kooperation.

Published: December 2018

Lithopedion (lithos = rock and paidion = child) is a rare condition that only occurs in 1.5 to 1.8% of extrauterine pregnancies and in 0.00045% of all pregnancies. It consists of an ectopic pregnancy in which the fetus dies but cannot be reabsorbed by the mother's body, which then coats it in a calcium-rich substance. We present the case of a 77-year-old woman with an incidental diagnosis of a lithopedion, which had been retained in her left pelvis for presumably 40 years.
