The purpose of this study was to adapt and validate a Coping Inventory for Competitive Sport (ISCCS), establishing its psychometric properties and its dimensional structure. Participants were 306 athletes from different sports, aged between 14 and 28 years (45.7% males and 54.3% females), who completed the ISCSS along with other measures of constructs theoretically related to coping. Factor analysis identified eight factors that merged in three high-order dimensions representing task-oriented coping, emotion-oriented coping and disengagement-oriented coping. The factors showed appropriate reliability (Cronbach alpha and factor correlations), convergent validity (correlations with COPE Inventory scales) and concurrent validity (correlations with CSAI-2 and PANAS scales). It is concluded that the Spanish version of the ISCCS has proved to be a valid and reliable instrument to identify and assess competitive coping strategies, allowing psychological intervention to improve athletes' performance.

A new twofold interpenetrated 3D metal-organic framework (MOF), namely, poly[[μ-aqua-diaqua{μ-2,2'-[terephthaloylbis(azanediyl)]diacetato}barium(II)] dihydrate], {[Ba(CHNO)(HO)]·2HO}, (I), has been assembled through a combination of the reaction of 2,2'-[terephthaloylbis(azanediyl)]diacetic acid (TPBA, HL) with barium hydroxide and crystallization at low temperature. In the crystal structure of (I), the nine-coordinated Ba ions are bridged by two μ-aqua ligands and two carboxylate μ-O atoms to form a 1D loop-like Ba-O chain, which, together with the other two coordinated water molecules and μ-carboxylate groups, produces a rod-like secondary building unit (SBU). The resultant 1D polynuclear SBUs are further extended into a 3D MOF via the terephthalamide moiety of the ligand as a spacer.

Fluid flow across a Riga Plate is a specialized phenomenon studied in boundary layer flow and magnetohydrodynamic (MHD) applications. The Riga Plate is a magnetized surface used to manipulate boundary layer characteristics and control fluid flow properties. Understanding the behavior of fluid flow over a Riga Plate is critical in many applications, including aerodynamics, industrial, and heat transfer operations.

Statement Of Problem: Different factors affect 3-dimensionally (3D) printed resin products. However, evidence on the effect of the print orientation on resin dental devices is lacking.
Purpose: The purpose of this systematic review and meta-analysis was to assess the impact of print orientation on the properties and accuracy of 3D printed implant surgical guides, occlusal devices, clear orthodontic retainers, and aligners.

Composite gels are a type of soft matter, which contains a continuous three-dimensional crosslinked network and has been embedded with non-gel materials. Compared to pure gels, composite gels show high flexibility and tunability in properties and hence have attracted extensive interest in applications ranging from cancer therapy to tissue engineering. In this study, we incorporated triethylenetetramine (TETA)-functionalized cobalt ferrite nanoparticles (ANPs) into a hydrogel consisting of sodium alginate (SA) and methyl cellulose (MC), and examined the resulting composite gels for controlled drug release.

The effective prevention and treatment of anastomotic leakage after intestinal anastomosis for colorectal diseases is still a major clinical challenge. In order to assist intestinal anastomosis healing and avoid anastomotic leakage caused by high tension, low blood supply or infection, we designed a double-layer nanofiber intestinal anastomosis scaffold, which was composed of electrospun PTMC/PHA nanofibers as the main layer, and electrospun PVA/OHA-Gs nanofibers with antibacterial properties as the antibacterial surface layer. This double-layer scaffold has good toughness, its maximum tensile force value could reach 8 N, elongation could reach 400 %, and it has hydrophilic properties, and its contact angle was about 60°.
