Effect of the FIT Taijipao on 20-30-Year-Old Adults’ Cardiorespiratory Function

The FIT taijipao is a personalized fitness run, based on tai chi thought, and taking physiological index heart rate as the assessment of exercise load standard. According to the current research, there is no clear study to confirm its health benefits. Therefore, this study intended to examine the effects of FIT taijipao on cardiorespiratory function for 20-30 years old adults. 60 volunteers were recruited from a university of Sichuan province, China. After the volunteers signed informed consent, they were randomly divided into the experimental group (30 students) and the control group (30 volunteers). The experimental group had the FIT taijipao twice a week guided by professionals, while the control group kept their original lifestyle. During the experiment, the baseline survey, heart rate and other health indexes of all the volunteers were assessed. In the final, there were 21 experimenters in the experimental group (6 males and 15 females) and 15 in another group (5 males and 10 females). The study processed the data in group by SPSS22.0 Paired T test and independent T test were conducted. After the 3-month experiment, it was found heart rate at rest (HRrest) had a significant downward trend. There was a highly significant difference in the experiment group’s HRrest before and after the experiment. Moreover, the quantitative load of the experimental group was 5 km / h or 8.3 km / h, the downward trend of HR was effectively lower than that before the experiment. It is suggested that the FIT taijipao has effects on reducing the oxygen consumption of heart contraction, the load of heart ejection and the work of heart in adults aged 20 to 30

catena-Poly[[trimethyl­tin(IV)]-μ-2-(2-chloro­phenyl)­acetato]

In the title polymeric coordination compound, [Sn(CH3)3(C8H6ClO2)]n, the Sn atoms exhibit a distorted trigonal-bipyramidal geometry with the carboxyl­ate O atoms of the 2-chloro­phenyl­acetato ligands in axial positions and with the equatorial sites occupied by the three methyl groups. Adjacent Sn atoms are bridged by coordination to the two O atoms of each 2-chloro­phenyl­acetato ligand, forming a chain structure

Intuitionistic Trapezoidal Fuzzy Multiple Criteria Group Decision Making Method Based on Binary Relation

The aim of this paper is to develop a methodology for intuitionistic trapezoidal fuzzy multiple criteria group decision making problems based on binary relation. Firstly, the similarity measure between two vectors based on binary relation is defined, which can be utilized to aggregate preference information. Some desirable properties of the similarity measure based on fuzzy binary relation are also studied. Then, a methodology for fuzzy multiple criteria group decision making is proposed, in which the criteria values are in the terms of intuitionistic trapezoidal fuzzy numbers (ITFNs). Simple and exact formulas are also proposed to determine the vector of the aggregation and group set. According to the weighted expected values of group set, it is easy to rank the alternatives and select the best one. Finally, we apply the proposed method and the Cosine similarity measure method to a numerical example; the numerical results show that our method is effective and practical

N′-[(E)-3-Pyridylmethyl­idene]benzo­hydrazide

The title compound, C13H11N3O, was prepared by the reaction of benzohydrazide and nicotinaldehyde. The dihedral angle between the planes of the two aromatic rings is 47.78 (9)°. The crystal structure is stabilized by inter­molecular N—H⋯N hydrogen-bonding inter­actions

(E)-2-Meth­oxy-6-(thia­zol-2-ylimino­meth­yl)phenol

The title compound, C11H10N2O2S, displays an E configuration about the C=N bond. The mean planes of the thia­zole and benzene rings make a dihedral angle of 9.32 (18)°. Intra­molecular O—H⋯N hydrogen bonds are found in the crystal structure

3,3′-Oxybi[isobenzofuran-1(3H)-one]

The title compound, C16H10O5, consists of two isobenzofuran-1(3H)-one moieties which are linked by a bridging O atom. The two halves of the mol­ecule display approximate non-crystallographic mirror symmetry. The dihedral angle between the two isobenzofuran-1(3H)-one ring systems is 53.18 (6) Å. Two chiral carbon centres are observed in the compound, but their absolute configurations could not be determined. In the crystal structure, inter­molecular C—H⋯O hydrogen bonds link mol­ecules into zigzag chains along c. Additional C—H⋯O inter­actions connect adjacent chains

3-[(3-Oxo-1,3-dihydro­isobenzofuran-1-yl)amino]benzoic acid

In the title compound, C15H11NO4, the dihedral angle formed by the benzene ring and isobenzofuran ring system is 67.82 (5) Å. The crystal structure is stabilized by inter­molecular O—H⋯O and N—H⋯O hydrogen-bonding inter­actions
