The previously known bismuth telluride iodides, BiTeI and Bi₂TeI, offer physical properties relevant for spintronics. Herewith a new cousin, Bi₃TeI (sp.gr. R3m, a = 440.12(2) pm, c = 3223.1(2) pm), joins the ranks and expands this structural family. Bi₃TeI = [Bi₂][BiTeI] represents a stack with strictly alternating building blocks. Conditions for reproducible synthesis and crystal-growth of Bi₂TeI and Bi₃TeI are ascertained, thus yielding platelet-like crystals on the millimeter size scale and enabling direct measurements. The crystal structures of Bi₂TeI and Bi₃TeI are examined by X-ray diffraction and electron microscopy. DFT calculations predict metallic properties of Bi₃TeI and an unconventional surface state residing on various surface terminations. This state emerges as a result of complex hybridization of atomic states due to their strong intermixing. Our study does not support the existence of new stacking variants BiₓTeI with x > 3; instead, it indicates a possible homogeneity range of Bi₃TeI. The series BiTeI–Bi₂TeI–Bi₃TeI illustrates the influence of structural modifications on topological properties.

Functionally, they represent hybrids of P450 monooxygenases and heme peroxidases; phylogenetically they belong to the family of heme-thiolate peroxidases. Two UPOs from the basidiomycetous fungi Agrocybe aegerita (AaeUPO) and Marasmius rotula (MroUPO) converted 35 out of 40 compounds listed as EPA priority pollutants, including chlorinated benzenes and their derivatives, halogenated biphenyl ethers, nitroaromatic compounds, polycyclic aromatic hydrocarbons (PAHs) and phthalic acid derivatives. These oxygenations and oxidations resulted in diverse products and-if at all-were limited for three reasons: (i) steric hindrance caused by multiple substitutions or bulkiness of the compound as such (e.g., hexachlorobenzene or large PAHs), (ii) strong inactivation of aromatic rings (e.g., nitrobenzene), and (iii) low water solubility (e.g., complex arenes). The general outcome of our study is that UPOs can be considered as extracellular counterparts of intracellular monooxygenases, both with respect to catalyzed reactions and catalytic versatility. Therefore, they should be taken into consideration as a relevant biocatalytic detoxification and biodegradation tool used by fungi when confronted with toxins, xenobiotics and pollutants in their natural environments.

During the examination period from June until December 2014, one-dimensional isometric trunk strength measurements were carried out on healthy, middle-aged probands using the biofeedback device "Pegasus". The aim was to check out the predefined standard values of the company BfMC and generate standard value ranges for muscular imbalances. Furthermore, these examinations were used to capture occurring forces on other levels to assess their impact on one-dimensional measurements. A standardized warm up was followed by the determination of the maximum trunk strength in flexion, extension, rotation and lateral inclination. Two measurements on 54 probands at the age of 22.8 ± 3.3 years and an average BMI of 28.9 ± 3.2 were conducted. In addition, the deviating forces were determined. In target-actual value comparison, the probands were about 17.1% above the normal range of their respective age groups, with an average isometric trunk strength development in all six directions of movement of 835Nm. For the male probands it was also found out that they positioned themselves 63.6% above (average?). The female probands in total were also within the normal range, but 200Nm less power was generated and 34% did not reach the normal range. Looking at the deviating forces, it is noticeable that 549.1 Nm (54%) were also applied in the other anatomic plains. Here, there were clear differences between the deviating forces in the isometric testing in the sagittal and frontal plain. In the measurement results of the sagittal plain (Ext; Flex), the deviating forces were 45.8Nm (29.9%) on average in the frontal and transverse direction. In the measurement results of lateral inclination and rotation, the deviating forces were 95.3% and 110% in sagittal and transverse direction. As a result, it can be noted that, despite the absence of pain, postural imbalances and diseases of the spine, more than half of the forces cannot be generated according to the axis. At this, synergistic functions seem to be physiological in this scope, in order to produce maximum plain equitable forces which basically questions one-dimensional measurements. The test results show significant deviations from the normal range, which raises the issue of the relevance of the defined standard values based on the evaluation of isometric force development. Further studies will have to prove the relevance of three-dimensional maximum force measurements.

Also it is capable to predict a healthy aging process and the future morbidity. Because of these facts the handgripstrength is used in the capacity-diagnostics for employment. Aim of this study was to examine the deficits of people from the second labour market comparative to people out of the first labour market. To expose these deficits the handgripstrength of 19 people(nmale=14; nfemale=5) out of the second labour market was measured with an handdynamometer and compared to the average of 28000 people from the first labour market. The results have shown that there is no lack of perfomance in the handgripstrength of people from the second labour market. Conclusively the handgripstrength as an important requirement for work and reference of the muscural capacity, is not the limiting factor for an employment in the first labour market.

In the individual manual-therapeutic treatment mobilizing techniques are mainly used in the spinal column. The target of this study is to demonstrate the change in segmental mobility of the thoracic spine with asymptomatic subjects. For that an anterior mobilization of the Evjenth/Kaltenborn concept was used. 15 subjects were examined concerning segmental limitations. 11 subjects were included in the study. The subjects had no complaints or preexisting diseases in the spinal column. Their limited segments in area of the thoracic spine were mobilized on two days of treatment with 5 repetitions and a duration of 50 seconds. In the first treatment a steady pressure of 100 N was applied by using a mobilization wedge. In the second the pressure increased to 140 N. The measurement of the mobility was carried out with the MediMouse method. In the functional tests of the lateral and frontal finger-to-ground distance as well as the thoracic respiratory mobility, the results of both treatments confirmed a significant practical relevance of the manual-therapeutic mobilization treatment of the thoracic spine. Segmental mobility improvements were also seen, but they need further investigation with regard to the sustainability of the measurement results.

An insight in the diagnostic of speed strength of the handball players T2 - The International Disabled People's Day - XXIII edition - Life without Pain/Healthy Children - Healthy Europe N2 - An important performance perequisites in men handball are the conditional abilities. Especially the sprinting skills and the bounce and reactive capacities of the handball players are convenient. Increasingly performance diagnostic is transferred to the supporting physiotherapists so as, in case of motoric malformation, targeted adjustments affecting the training contants can be made from a physiotherapeutic perspective. This study takes up the aspect of performance diagnostic in the range of speed and reactive strength and pusues their comperance of the 1st and 2nd team of the handball club Elbflorenz Desden (HCE, N=23). Both teams completed a standardized warm up. Based on a light barrier system the speed strength was measured during a 20 meter sprint. The measurement of the reactive strength followed as drop jump, whereby the ground contact time of the players was collected by using the Opto jump next. The outcome showed significantly higher results in speed and reactive strength of the 1st team. Due to the performance differences of the two teams, players of the 2nd team should not be playing in the 1st team without acomplishing a specific training of speed strength. On the one hand it would lead to a poorer overall performance and on the other hand increase the susceptibility to injury.

Athletes rarely return to the peak of performance or are limited in their ability to perform their sport. Performance tests for ACLR are still immature and often unspecific. In Judo, the ability to stand on one's feet is an essential prerequisite for many situations. An unstable standing position also promotes knee injuries. In order to check the stability of the single leg stand, a controlled test-re-test design is used in the present study. Two groups are included: A (n=27): Judoka without anamnestically relevant injuries of the lower extremities or the back and B (n=17): Judoka 5.06 ± 1.06 years after ACLR. A one-legged hop test up on a piezoelectric force plate is examined for reliability with respect to the test repetition and validity with regard to the predicted identification of deficits in a side-by-side comparison. In this test, the test person jumps with one leg on the force plate at a defined distance and tries to stand as still as possible, which means that hardly any horizontal force is generated. Both tests are carried out one after the other with both legs and with sufficient break twice each. In group A, there were no significant differences (p>0.05) between the subjectively better leg and the subjectively worse leg, or the leg in the front and rear of the kumi-kata in Judo. In group B, in the first experiment with the ACLR leg, the test persons generate a significantly higher horizontal force in a 95% confidence interval of the bilateral coefficient of CI=[0.16-0.76] compared to the side not affected (p=0.017). In the test repetition, Group B generates with the affected leg significantly less horizontal force surges than in the first attempt. No significant differences in lateral comparison could be measured, although there is a reliability coefficient of r=0.89 for the ACLR leg, but only r=0.35 for the unaffected leg and r=0.53 for group A. It is concluded that the test for asymptomatic judokas cannot be regarded as sufficiently selective due to the low requirement. In group B, in the second experiment, a feed-forward model including pre-activation based on empirical values from the first experiment could explain the improvement, which has led to no significant differences between legs.
