RESEARCHING OF THE JOINT ANGLES ON THE LEGS, DURING THE SUPPORT PERIOD OF THE MOVE STEP IN CLASSIC MOUNTAIN RUNNING

The purpose of the study is to clarify the kinematic picture of motor activity when overcoming slopes of different steepness in classic mountain running. Methods: Using a GPS device, the Map Source computer program, and additional mathematical calculations, we explored various mountain running courses to determine their gradient range. We then used the protractor to find terrain with slopes ranging from 0 to 16 degrees in 2-degrees increments for the subjects to run on. By video processing the video files with the computer software Kinovea, we determined the values of the angles of the ankle joint, knee joint and hip joint. Conclusions: As the inclines of running uphill increase, the angles in all three joints of the lower limbs decrease. In general, there are no large changes in the joint angles of moment of touching the support and the moment of maximum flexing, while at the moment of separation from the support, the joint angles decrease significantly with the increase of the downward slope. At all three moments of the support period (moment of touching the support; maximum flexing; separation from the support) at the different running slopes, the least change of angles was observed in the ankle joint

Relation between Chlamydia trachomatis, the trophoblast and preterm delivery

There is a connection between preterm labor and intrauterie infections which is well established in up to 40% of cases. Success of the interaction between the invading trophoblast at the maternal-fetal interface and the maternal immune system is an immunologically unique fact. In this process the trophoblast participates in both the immune suppression which is necessary for tolerance to the semialogenic fetus and the immune activation against damaging factors such as infections. Alterations in this type of cross-talk, as in the cases of infection-triggered inflammation by Chlamydia species, could result in pregnancy complications such as prematurity or spontaneous abortion.Related articles and clinical cases have been gathered and reviewed to establish the main mechanisms and to confirm the relationship between preterm labor and Chlamydia trachomatis infection

Co-existing structures in 105Ru

New positive-parity states, having a band-like structure, were observed in 105Ru. The nucleus was produced in induced fission reaction and the prompt gamma-rays, emitted from the fragments, were detected by the EUROBALL III multi-detector array. The partial scheme of excited 105Ru levels is analyzed within the Triaxial-Rotor-plus-Particle approach

A Case of Unicornuate Uterus with Atypical Located Hyperstimulated Ovary after in Vitro Fertilization Pre-Embryo Transfer (IVF-ET)

The authors describe a case of a congenital Mullerian anomaly, uterus unicornis with missing right fallopian tube. An in Vitro Fertilization Pre-Embryo Transfer (IVF-ET) procedure was done and presently is known that the patient has left fallopian tube and left ovary, two kidneys, and right ovary is missing. No diagnostic laparoscopy and hysteroscopy were done, only hysterosalpingography (HSG) before the IVF procedure.  Several days after the follicular puncture of the left ovary the patient was urgently admitted to the hospital for specialized gynaecology in Varna. Transabdominal ultrasonography showed right ovary atypically located immediately next to the liver and with emerging theca-lutein cysts

In-beam fast-timing measurements in 103,105,107Cd

Fast-timing measurements were performed recently in the region of the medium-mass 103,105,107Cd isotopes, produced in fusion evaporation reactions. Emitted gamma-rays were detected by eight HPGe and five LaBr3:Ce detectors working in coincidence. Results on new and re-evaluated half-lives are discussed within a systematic of transition rates. The $7/2_1^+$ states in 103,105,107Cd are interpreted as arising from a single-particle excitation. The half-life analysis of the $11/2_1^-$ states in 103,105,107Cd shows no change in the single-particle transition strength as a function of the neutron number

Core-coupled states and split proton-neutron quasi-particle multiplets in 122-126Ag

Neutron-rich silver isotopes were populated in the fragmentation of a 136Xe beam and the relativistic fission of 238U. The fragments were mass analyzed with the GSI Fragment separator and subsequently implanted into a passive stopper. Isomeric transitions were detected by 105 HPGe detectors. Eight isomeric states were observed in 122-126Ag nuclei. The level schemes of 122,123,125Ag were revised and extended with isomeric transitions being observed for the first time. The excited states in the odd-mass silver isotopes are interpreted as core-coupled states. The isomeric states in the even-mass silver isotopes are discussed in the framework of the proton-neutron split multiplets. The results of shell-model calculations, performed for the most neutron-rich silver nuclei are compared to the experimental data

Detailed characterization of a laboratory magnetized supercritical collisionless shock and of the associated proton energization

Collisionless shocks are ubiquitous in the Universe and are held responsible for the production of nonthermal particles and high-energy radiation. In the absence of particle collisions in the system, theory shows that the interaction of an expanding plasma with a pre-existing electromagnetic structure (as in our case) is able to induce energy dissipation and allow shock formation. Shock formation can alternatively take place when two plasmas interact, through microscopic instabilities inducing electromagnetic fields that are able in turn to mediate energy dissipation and shock formation. Using our platform in which we couple a rapidly expanding plasma induced by high-power lasers (JLF/Titan at LLNL and LULI2000) with high-strength magnetic fields, we have investigated the generation of a magnetized collisionless shock and the associated particle energization. We have characterized the shock as being collisionless and supercritical. We report here on measurements of the plasma density and temperature, the electromagnetic field structures, and the particle energization in the experiments, under various conditions of ambient plasma and magnetic field. We have also modeled the formation of the shocks using macroscopic hydrodynamic simulations and the associated particle acceleration using kinetic particle-in-cell simulations. As a companion paper to Yao et al. [Nat. Phys. 17, 1177-1182 (2021)], here we show additional results of the experiments and simulations, providing more information to allow their reproduction and to demonstrate the robustness of our interpretation of the proton energization mechanism as being shock surfing acceleration
