Magnetization and electrical resistivity measurements were carried out for polycrystallineMn2Sb1−xGex (0.05 ≤ x ≤ 0.2) in magnetic fields up to 16 T in the 4.2 - 600 K temperaturerange in order to investigate the magnetic and the electrical properties under high magnetic fields. Mn2Sb0.92Ge0.08 showed a Curie temperature, TC, of 532 K and a first order magnetic transitionfrom a ferrimagnetic (FRI) to an antiferromagnetic (AFM) phase at Tt = 230 K with decreasingtemperature in a zero magnetic field. With increasing x, TC decreased and Tt increased. ForMn2Sb0.92Ge0.08, a matamagnetic transition from an AFM to a FRI phase was observed at 215 K. The magnetic phase diagram of Mn2Sb1−xGex is presented.

Much attention has been paid to PAY (Personal Air Vehicle) as a new-generation small aircraft, It is expected that PAY will be widely used as a short-range transport aircraft in the future for countermeasure against traffic jam, One of the key technologies to make PAY much popular is to enhance the safety, which is crucial to small planes, In order to enhance the safety of PAY, mild-stall high-lift characteristics of the wing are especially needed. This study aims to propose a mild-stall wing with a fixed slat for PAY use, Two mild-stall airfoils are combined to form a new rectangular wing: NACA4415 and SLAT4415, NACA4415 is known as a conventional mild-stall airfoil, and SLAT4415 is a fixed slat airfoil based on NACA4415 for further improvement in stall characteristic, The higher lift characteristic ofSLAT4415 was obtained via the optimization by Genetic Algorithm. Designed wings composed ofNAC4415 and SLAT4415 airfoils are numerically analyzed by solving the Navier-Stokes equations on the unstructured mesh to examine the performance at high-angle of attack for low-speed region, The computational results indicate that designed wings are able to achieve mild-stall characteristics, Lift coefficients of the designed wings tend to drop at 22 degrees of A.o.A, however, increase again as A.o.A becomes higher, For further analysis, numerical simulations for the wing that has a taper or that has only SLAT4415 airfoil were also conducted, As a result, it was proved that the designed rectangular wing that has SLAT4415 airfoil of fixed slat only in outboard wing had very mild stall characteristic.

At a training site that encourages athletes to generate movement, it may not be possible to successfully generate a sense of movement simply by presenting the athletes with step-by-step practice published in general instruction manuals; the coach is required to tailor the road individually to the goal. In competitive sports that require high performance, there is a strong interest in the optimal road of coaching. However, few studies have clarified the coachs ability to build practice procedures by real coaching spot. The purpose of this study was to focus on the ability of coaches to build staged practice, and to present how to teach “Any 3/3 travel in flairs with 1/1 Spindle inside two circles (Urzica 2)” in the pommel horse in gymnastics, and by considering this from a phenomenological standpoint, we aim to gain new knowledge regarding the structure and modification ability of coachs practice stages. The method of this study was to select University Gymnast-A from among 20 male university gymnast participants and analyze them. The first step was to conduct a structural analysis of the target elements as a prerequisite for constructing the technical training path. Next, in order to analyze the structure of the practice stages, kinesthetic coaching for Gymnast-A was presented. Finally, the coachs kinesthetic orientation was analysed from a phenomenological standpoint. In the analysis, a phenomenological reflective analysis was conducted to examine how the coach constructed practice stage suitable for the players from the perspective of kinesthetic meaning and suitability of arrangement. It is important to get high scores in gymnastics competition to this element (Urzica 2) acquiring, and it is one that top gymnasts in recent years have incorporated into their performance program. This phenomenological analysis of the construction of the practice stages of the element not only provided new insights into the construction of the coachs practice stages and his ability to modify them, it also provided effective insights into the coaching of high-difficulty elements in gymnastics.

<P>Merozoite surface protein 1 of <I>Plasmodium vivax</I> (PvMSP1), a glycosylphosphatidylinositol-anchored protein (GPI-AP), is a malaria vaccine candidate for <I>P. vivax</I>. The paralog of PvMSP1, named <I>P. vivax</I> merozoite surface protein 1 paralog (PvMSP1P; PlasmoDB PVX_099975), was recently identified and predicted as a GPI-AP. The similarities in genetic structural characteristics between PvMSP1 and PvMSP1P (e.g., size of open reading frames, two epidermal growth factor-like domains, and GPI anchor motif in the C terminus) led us to study this protein. In the present study, different regions of the PvMSP1P protein, demarcated based on the processed forms of PvMSP1, were expressed successfully as recombinant proteins [i.e., 83 (A, B, and C), 30, 38, 42, 33, and 19 fragments]. We studied the naturally acquired immune response against each fragment of recombinant PvMSP1P and the potential ability of each fragment to bind erythrocytes. The N-terminal fragment (83A) and two C-terminal fragments (33 and 19) reacted strongly with sera from <I>P. vivax</I>-infected patients, with 50 to 68% sensitivity and 95 to 96% specificity, respectively. Due to colocalization of PvMSP1P with PvMSP1, we supposed that PvMSP1P plays a similar role as PvMSP1 during erythrocyte invasion. An <I>in vitro</I> cytoadherence assay showed that PvMSP1P, especially the 19-kDa C-terminal region, could bind to erythrocytes. We also found that human sera from populations naturally exposed to vivax malaria and antisera obtained by immunization using the recombinant molecule PvMSP1P-19 inhibited <I>in vitro</I> binding of human erythrocytes to PvMSP1P-19. These results provide further evidence that the PvMSP1P might be an essential parasite adhesion molecule in the <I>P. vivax</I> merozoite and is a potential vaccine candidate against <I>P. vivax</I>.</P>

Purpose: Patients with pathological stage T1N+ or T2-3N0 gastric cancer may experience disease recurrence following curative gastrectomy. However, the current Japanese Gastric Cancer Treatment Guidelines do not recommend postoperative adjuvant chemotherapy for such patients. This study aimed to identify the prognostic factors for patients with pT1N+ or pT2-3N0 gastric cancer using a multi-institutional dataset. Materials and Methods: We retrospectively analyzed the data obtained from 401 patients with pT1N+ or pT2-3N0 gastric cancer who underwent curative gastrectomy at 9 institutions between 2010 and 2014. Results: Of the 401 patients assessed, 24 (6.0%) experienced postoperative disease recurrence. Multivariate analysis revealed that age ≥70 years (hazard ratio [HR], 2.62; 95% confidence interval [CI], 1.09-7.23; P=0.030) and lymphatic and/or venous invasion (lymphovascular invasion (LVI): HR, 7.88; 95% CI, 1.66-140.9; P=0.005) were independent prognostic factors for poor recurrence-free survival. There was no significant association between LVI and the site of initial recurrence. Conclusions: LVI is an indicator of poor prognosis in patients with pT1N+ or pT2-3N0 gastric cancer.

The expression of stage-specific embryonic antigens (SSEAs) was determined in several types of canine cancer cells. Flow cytometry showed SSEA-1 expression in glioblastoma, melanoma, and mammary cancer cells, although none expressed SSEA-3 or SSEA-4. Expression of SSEA-1 was not detected in lymphoma, osteosarcoma, or hemangiosarcoma cell lines. Relatively stable SSEA-1 expression was observed between 24 and 72 h of culture. After 8 days in culture, sorted SSEA-1− and SSEA-1+ cells re-established SSEA-1 expression to levels comparable to those observed in unsorted cells. Our results document, for the first time, the expression of SSEA-1 in several canine cancer cell lines.

An overview is given on the work of the Laboratory of Nuclear Energy Systems at ETH, Zurich (ETHZ) and of the Laboratory of Thermal Hydraulics at Paul Scherrer Institute (PSI), Switzerland on tight-lattice bundles. Two-phase flow in subchannels of a tight triangular lattice was studied experimentally and by computational fluid dynamics simulations. Two adiabatic facilities were used: (1) a vertical channel modeling a pair of neighboring subchannels; and (2) an arrangement of four subchannels with one subchannel in the center. The first geometry was equipped with two electrical film sensors placed on opposing rod surfaces forming the subchannel gap. They recorded 2D liquid film thickness distributions on a domain of 16 × 64 measuring points each, with a time resolution of 10 kHz. In the bubbly and slug flow regime, information on the bubble size, shape, and velocity and the residual liquid film thickness underneath the bubbles were obtained. The second channel was investigated using cold neutron tomography, which allowed the measurement of average liquid film profiles showing the effect of spacer grids with vanes. The results were reproduced by large eddy simulation + volume of fluid. In the outlook, a novel nonadiabatic subchannel experiment is introduced that can be driven to steady-state dryout. A refrigerant is heated by a heavy water circuit, which allows the application of cold neutron tomography

Study Design: Prospective experimental study on humans. Purpose: To determine whether postural differences during a low-speed impact are observed in the sagittal and axial views, particularly in a relaxed state. Overview of Literature: Three-dimensional motion capture systems have been used to analyze posture and head-neck-torso kinematics in humans during a simulated low-speed impact, yet little research has focused on the axial view. Since a seatbelt asymmetrically stabilizes a driver’s right shoulder and left lower waist into the seat, it potentially creates movement in the axial view. Methods: Three healthy adult men participated in the experimental series, which used a low-speed sled system. The acceleration pulse created a full sine shape with a maximum acceleration of 8.0 m/s2 at 500 ms, during which the kinematics were evaluated in relaxed and tensed states. The three-dimensional motion capture system used eight markers to record and analyze body movement and head-neck-torso kinematics in the sagittal and axial views during the low-speed impact. Head and trunk rotation angles were also calculated. Results: Larger movements were observed in the relaxed than in the tensed state in the sagittal view. The cervical and thoracic spine flexed and extended, respectively, in the relaxed state. In the axial view, larger movements were also observed in the relaxed state than in the tensed state, and the left shoulder rotated. Conclusions: During simulated frontal impact, the rotation angle between the head and trunk was significantly larger in the relaxed state. Therefore, we recommend also observing movement in the axial view during impact tests.
