In particular, grazed semi-natural grasslands and woody elementssupport farmland birds, but little is known about their relative effects on bird diversity and community composition. In addition,the relative importance of local habitat versus landscape composition remains unclear. We investigated how the presence ofsemi-natural grasslands, the number of woody elements and the composition of the wider agricultural landscape affect bird spe-cies richness, true diversity (exponential Shannon diversity) and species composition. Bird communities were surveyed fourtimes on 16 paired transects of 250 m each with 8 transects placed between a cropfield and a semi-natural grassland and 8transects between two cropfields with no semi-natural grasslands in the vicinity. The number of woody elements around trans-ects was selected as an important predictor in all models, having a positive effect on species richness and true diversity, whilethe local presence of semi-natural grasslands was not selected in the best models. However, species richness and true diversityincreased with increasing cover of ley and semi-natural grasslands, whereas species composition was modified by the coverageof winter wheat at the landscape scale. Furthermore, bird species richness, true diversity and species composition differedbetween sampling dates. As bird diversity benefited from woody elements, rather than from the local presence of semi-naturalgrasslands as such, it is important to maintain woody structures in farmland. However, the positive effect of grassland at thelandscape scale highlights the importance of habitat variability at multiple scales. Because species richness and true diversitywere affected by different landscape components compared to species composition, a mosaic of land-use types is needed toachieve multiple conservation goals across agricultural landscapes.

In contrast, the knowledge concerning the differing context factors and the underlying mechanisms of current PSC which could inform policy recommendations is scant. The study aims at unravelling the contexts, mechanisms and outcomes of PSC for UMRs. For a realist review (RR), scientific evidence and gray literature were synthesised consistent with the RAMESES publication standards for realist synthesis. Based on an iterative keyword search in electronic databases (e.g., PubMed) and screening, 34 works from 2005 to 2019 were included in a realist synthesis. Theory-informed context-mechanism-outcome configurations (CMOs) were extracted, to explain underlying processes and mechanisms. Characterised by their interrelatedness, the dominant CMOs included the UMRs' intersections of transitions (e.g., adolescence and migration), their needs for culture-, and gender-sensitive PSC, and the undersupply of PSC. These contexts and outcomes are mediated by pre-, peri- and post-migratory stressors as well as care structures and are moreover influenced by overarching discourses and concepts. They comprise adverse and beneficial mechanisms in the PSC of UMRs. The existing literature grasps the PSC of UMRs by different disciplines and approaches but does not offer a comprehensive overview on micro-macro intersections and included discourses. The inclusion of lay perspectives and an intersectional approach could inform health service research. The reflection of UMR-related categorical constructs of resilience and vulnerability, discourses of othering, as well as restrictive health policies may guide policy recommendations.

Thereby, the knowledge about an output displacement or force as well as the detailed mounting position is not necessary for the application. The newly developed objective function makes use of the varying stress distribution in the cross section of flexible structures. Hence, each element of the design space must be evaluated with respect to its stress state. Therefore, the method prefers elements experiencing a bending or shear load over elements which are mainly subjected to membrane stresses. In order to determine the stress state of the elements, we use the principal stresses at the Gauss points. For demonstrating the feasibility of the new topology optimization approach, three academic examples are presented and discussed. As a result, the developed sensitivity-based algorithm is able to find usable flexible design concepts with a nearly discrete 0 − 1 density distribution for these examples.

Dadurch ist, forciert durch die Verfolgung unterschiedlicher Interessen, ein Bild des generellen motorischen Leistungsverlustes entstanden, das mit Blick auf die gesellschaftliche Leistungsfähigkeit unter anderem physiotherapeutische Interventionen im Vorschulbereich postuliert. Die hier vorliegende Studie widmet sich dieser Thematik und untersucht den Status konditioneller Fähigkeiten von Vorschulkindern. Dabei wurden ausgewählte Kindergärten des Großraumes Dresden mittels Deutschem Motorik – Test unter weitestgehend standardisierten Feldbedingungen analysiert. Im Ergebnis zeigt sich, dass im Bereich der konditionellen Fähigkeiten nur die Kraftausdauer der Bauchmuskulatur und die aerobe Ausdauerleistungsfähigkeit Defizite aufweisen. Letzteres verdeutlicht sich signifikant bei 6-jährigen Vorschulkindern, die in altersgemischten Gruppen betreut werden. Insgesamt ist zu schlussfolgern, dass ein weit angelegter Einsatz physiotherapeutischer Interventionen für die gezogene Stichprobe im Bereich der Dimension „konditionelle Fähigkeiten“ nicht notwendig ist. Unter primärpräventivem Charakter ist aber die Kräftigung der Bauchmuskulatur (hier Kraftausdauer) und die Verbesserung der aeroben Ausdauerleistungsfähigkeit nachzusteuern.

Vor diesem Hintergrund ist es nicht verwunderlich, dass die kindliche Sprachentwicklung unter besonderer elterlicher, erzieherischer und ärztlicher Beobachtung steht. In der nationalen Fachliteratur wird immer wieder zur Diskussion gestellt, dass die Zahl von Sprachentwicklungsstörungen einschließlich der daraus resultierenden Lern- und Verhaltensstörungen in den letzten Jahren drastisch angestiegen sei. Um dieser Frage nachzugehen, wurden die vollständigen Datensätze des Kinder- und Jugendärztlichen Dienstes (KJÄD) der Einschulungsuntersuchungen der Jahre 2008/2009, 2009/2010 und 2010/2011 des Gesundheitsamtes Dresden ausgewertet. Für die Erfassung von Sprachentwicklungsauffälligkeiten kommt seit dem Schuljahr 2004/05 das Screening des Entwicklungsstandes S-ENS zum Einsatz. Ziel dieser Arbeit war es, die aktuellen Prävalenzraten kindlicher Sprachentwicklungsauffälligkeiten in Dresden zu ermitteln. Für die Beurteilung möglicher sozialer Einflüsse auf die Sprachentwicklung wurde ein weiterer unabhängiger Datensatz der Kommunalen Bürgerumfrage aus dem Jahr 2010 hinzugezogen. Die Ergebnisse bestätigten im Untersuchungszeitraum einen leichten Anstieg der auffälligen Testergebnisse des KJÄD von insgesamt 2,8 Prozent, welcher zwischen den einzelnen Ortsämtern sehr stark divergiert. Der Extremgruppenvergleich zeigte anhand der Daten der KBU mögliche Hinweise für soziale Einflüsse auf die Sprachentwicklung des Kindes auf. Die Ergebnisse unterscheiden sich mit 12,5 Prozent zwischen den Punktwertresultaten des S-ENS und der Gesamtbeurteilung des Sprachergebnisses der Ärzte deutlich. Die Ergebnisse dieser Arbeit bestätigen keinen eindeutigen Anstieg der kindlichen Sprachauffälligkeiten in Dresden. Eine weitere Erfassung des Sprachstandes mit Hilfe des S-ENS sollte kritisch überdacht werden. Ein kausaler Einfluss sozioökonomischer Faktoren auf die Sprachentwicklung war anhand der Datensätze nicht beurteilbar und sollte in weiteren Studien untersucht werden.

Therefore these investigations must represent the basis for any uses of assessment. The goniometry is inevitable for the documentation of the mobility of joints. The kind of test procedures and their quality are however most contentious. The present study examined in a three-way blinded, randomized test-retest design, with for each n=10 test person and k=20 examiners, the intertester reliability (IER) and Intratester reliability (IAR) of the measuring procedures: “short and long goniometer”, “visual estimation”, “electrical goniometer” and “Vitronic Body Scanner with and without localization markers”. For the test procedures short, long and electrical goniometer weak IER and IAR (ICC 0,05). A diffuse international data situation makes a closing classification of the results more difficult and suggests the necessity for a high-quality meta-analysis to the topic.

Many studies reported which influence different refrigerant have on lowering the skin temperature, to the sensation of pain and the reabsorbing edema. In conclusion it can be stated that a lack of quality and low number of available studies, the efficacy of cryotherapy do not assign and the application after hip and knee arthroplasty is even contradictory. Striking are the various types of information with regard to the duration of application, shape and intensity. Because of the missing evidence for sensibility of application intensity this study aimed to determine influential parameters with moderate cold (11°C) for improving the intensity control. 15 healthy subjects aged 23.2±1.26 were tested. The parameters BMI, fat mass and muscle mass were recorded. All subjects received a cold application by the invented and developed IceCube at the right knee joint for 15 minutes. The temperature was measured for six times with an infrared thermometer at five standardized points of the knee joint. During application and till the last measurement subjects were immobilized. The applied cold application resulted in a significant decrease of temperature in all measuring points concerning the pre-post-comparison. 20 minutes after removing the cuff significant temperature increases in 3 measurement points, still keeping below starting level, were remarked. Furthermore it is evident that the temperature differences of the muscular measuring points are significantly higher than those of the not muscular measuring points. Besides a higher fat portion leads due to the isolation effect in relation to musculature to significantly fewer variations in temperature. This realization is to be considered for an adequate intensity regulation. In order to confirm the force of expression of the results, it requires further investigations with higher test person numbers.

Diagnostically and therapeutically challenging to workers are mainly the biomechanical, the sensomotoric and psychosocial strain in the workplace. In case of illness with rehabilitative requirements should therefore medical therapy be dovetailed with work and work-related activities. That connection is a necessary development of rehabilitative care system in Germany, not least in view of the legal order of the German Pension Insurance to help injured patients and to support their return to work. In the work-related orientation of medical rehabilitation is the professional life of rehabilitation involved in all phases of therapy. The instruments for the diagnosis of occupational problems are both objectively and subjectively oriented Questionnaires with external and self-assessment, FCE systems (functional capacity evaluation) and medical documentation systems. The Ergos® Work Simulator is a psychophysical FCE system, which captures the individual motor skills in relation to the performance of job-specific requirement profiles. The evaluation of job performance is based on a profile pool of about 14,000 professional activities. The tests are standardized and analyze frequent physical aspects of the work (eg lifting, carrying) to ensure a realistic assessment.

This kind of injury is mainly based on intrinsic factors such as structural overload which accounts for 17% of all moderate and severe competition injuries. Following knee and ankle joint, hamstrings are the third most common structure to suffer from injuries. As previous reviews show, eccentric training, such as the Nordic Hamstring Exercise (NHE), can reduce hamstring injuries. However, in those reviews other sports in addition to soccer were also examined in one sample. Purpose: The aim of this review is to synthesize the best available evidence on the effectiveness of the NHE as an intervention in the prevention of hamstring injuries in soccer players. Methods: The search for the studies was done in the PubMed, PEDro, Cochrane Library and EB-SCO databases. There was no language or time restrictions. Titles, abstracts and full texts of the respective studies were verified by two independent reviewers and selected using the inclusion criteria. In addition, critical evaluation tools were used to assess the methodological qualities of the respective studies followed by data extraction in JBI SUMARI. Meta-analysis was performed. Results: Four studies were included in this systematic review. Three studies compared NHE as an intervention with conventional football training and one study conducted hamstring curls as a control intervention. The duration of the studies ranged from 2.5 to 6.75 months, with a total of 28312 NHE sessions and 25918 training sessions in the control groups. The intervention groups showed a total of 30 hamstring injuries and the control groups developed a total of 80 injuries. A sample of 1780 soccer players were examined, 909 in the intervention groups and 871 in the control groups. The overall mean odds' ratio was significantly below one (95% CI, P= 0.335). The probability of suffering a hamstring injury was between 0.22 and 0.53 times lower in the intervention group than in the control group. The test for heterogeneity showed no significance (I² = 9). Conclusion(s): The NHE can help to reduce hamstring injuries in football players. However, due to the small number of studies included, the result should be interpreted with caution and more clinical studies should be conducted in the future. Implications: Looking at the total number of days lost per player in a season, professional football has a total of approximately 25,900 days lost, which is three times more than in other sports. Every injury is associated with lost time and additional costs. This review aimed to examine a cost-efficient exercise for its preventive effect. To counteract injuries in soccer and the factors associated with them,. showing chances to reach those goals.

The device is called graphene-base heterojunction transistor (GBHT). The base-voltage controls the current of the device flowing from the emitter via graphene to the collector. The transit time for electrons passing by the ultrathin graphene layer is extremely short which makes the device very promising for high frequency RF-electronics. The output current of the device is saturated and clearly modulated by the base voltage. Further, the silicon collector of the GBHT is replaced by germanium to improve the device performance. This enabled the collector current to be increased by almost three orders of magnitude. Also, the common-emitter current gain (Ic/Ib) increased from 10-3 to approximately 0.3 for the newly designed device. However, the ON-OFF ratio of the improved germanium based GBHT has so far been rather low. Further optimizations are necessary in order to fully exploit the potential of the graphene-base heterojunction transistor.

In this study, we fabricated and analyzed a novel graphene-based transistor, which resembles the structure of the barristor but uses a different operating condition. This new device, termed graphene adjustable-barriers transistor (GABT), utilizes a semiconductor-based gate rather than a metal−insulator gate structure to modulate the device currents. The key feature of the device is the two graphene-semiconductor Schottky barriers with different heights that are controlled simultaneously by the gate voltage. Due to the asymmetry of the barriers, the drain current exceeds the gate current by several orders of magnitude. Thus, the GABT can be considered an amplifier with an alterable current gain. In this work, a silicon−graphene−germanium GABT with an ultra-high current gain (ID/IG up to 8 × 106) was fabricated, and the device functionality was demonstrated. Additionally, a capacitance model is applied to predict the theoretical device performance resulting in an on−off ratio above 106, a swing of 87 mV/dec, and a drivecurrent of about 1 × 106 A/cm2.
