This paper examines the effect of boarding on obesity among middle school students at boarding schools.

Quantitative, cross-sectional study.

Data from the China Education Panel Survey (CEPS) were analyzed. The CEPS samples middle school students from 7th grade to 9th grade in China.

The final sample included 3,892 observations of boarding school students.

Measures included body mass index (BMI) that determined obesity, boarding status, demographic information, and instruments for boarding status.

The instrumental variables approach based on the 2 stage least squares (2SLS) methodology was utilized. The endogenous models and the extended probit models were also applied to the data to confirm the robustness of the results.

Boarding has a significant negative effect on obesity for middle school boys but a smaller negative effect on obesity for middle school girls. Boarding was estimated to reduce obesity by roughly 14% (p < 0.01) among middle school boys and 6% (p > 0.1) among middle school girls. The overall estimated effect based on the pooled sample was about 10% (p < 0.01).

School or government policies that encourage boarding at school can reduce obesity among middle school students, at least for middle school boys. Boarding at school can be a positive factor in preventing and controlling obesity among middle school students.

X-ray crystallographic analysis revealed that different extents of interligand-contacting interactions between bis-β-diketonates and Pybox ligands produce different bis-β-diketonates arrangements around four EuIII ions and, thus, their specific symmetry in the final tetranuclear complexes. 2- Ph RRRR/2- Ph SSSS and 3- Ph RRRR/3- Ph SSSS are recognized as D2-symmetry, while 2- iPr RRRR/2- iPr SSSS self-assemblies possess pseudo C2h-symmetry. Due to different molecular symmetry, 2- Ph RRRR/2- Ph SSSS and 2- iPr RRRR/2- iPr SSSS crystals display different ligands orientation in their EuIII coordination spheres. selleck products The presence of pseudo σh-mirror symmetry in 2- iPr RRRR/2- iPr SSSS promotes a pair of distinguishable EuIII geometries. All the chiral self-assemblies exhibit almost identical photoluminescence emission spectra patterns of f-f transitions in the EuIII core. The EuIII self-assemblies exhibit intense CPL with different observed |glum| values (2- Ph RRRR/2- Ph SSSS ∼ |0.31|, 2- iPr RRRR/2- iPr SSSS ∼ |0.08|, 3- Ph RRRR/3- Ph SSSS ∼ |0.31| in chloroform).We investigate the magnetic resonance properties and exchange kinetics of guest molecules in a series of hetero-bimetallic capsules, [Co n Fe4-nL6]4- (n = 1-3), where L2- = 4,4'-bis[(2-pyridinylmethylene)amino]-[1,1'-biphenyl]-2,2'-disulfonate. H bond networks between capsule sulfonates and guanidinium cations promote the crystallization of [Co n Fe4-nL6]4-. The following four isostructural crystals are reported two guest-free forms, (C(NH2)3)4[Co1.8Fe2.2L6]·69H2O (1) and (C(NH2)3)4[Co2.7Fe1.3L6]·73H2O (2), and two Xe- and CFCl3-encapsulated forms, (C(NH2)3)4[(Xe)0.8Co1.8Fe2.2L6]·69H2O (3) and (C(NH2)3)4[(CFCl3)Co2.0Fe2.0L6]·73H2O (4), respectively. Structural analyses reveal that Xe induces negligible structural changes in 3, while the angles between neighboring phenyl groups expand by ca. 3° to accommodate the much larger guest, CFCl3, in 4. These guest-encapsulated [Co n Fe4-nL6]4- molecules reveal 129Xe and 19F chemical shift changes of ca. -22 and -10 ppm at 298 K, respectively, per substitution of low-spin FeII by high-spin CoII. Likewise, the temperature dependence of the 129Xe and 19F NMR resonances increases by 0.1 and 0.06 ppm/K, respectively, with each additional paramagnetic CoII center. The optimal temperature for hyperpolarized (hp) 129Xe chemical exchange saturation transfer (hyper-CEST) with [Co n Fe4-nL6]4- capsules was found to be inversely proportional to the number of CoII centers, n, which is consistent with the Xe chemical exchange accelerating as the portals expand. The systematic study was facilitated by the tunability of the [M4L6]4- capsules, further highlighting these metal-organic systems for developing responsive sensors with highly shifted 129Xe resonances.On account of its nonbiodegradable nature and persistence in the environment, perfluorooctanoic acid (PFOA) accumulates in water resources and poses serious environmental issues in many parts of the world. Here, we present the development of two fluorine-rich calix[4]arene-based porous polymers, FCX4-P and FCX4-BP, and demonstrate their utility for the efficient removal of PFOA from water. These materials featured Brunauer-Emmett-Teller (BET) surface areas of up to 450 m2 g-1, which is slightly lower than their nonfluorinated counterparts (up to 596 m2 g-1). FCX4-P removes PFOA at environmentally relevant concentrations with a high rate constant of 3.80 g mg-1 h-1 and reached an exceptional maximum PFOA uptake capacity of 188.7 mg g-1. In addition, it could be regenerated by simple methanol wash and reused without a significant decrease in performance.Economically feasible photosynthetic cultivation of microalgal and cyanobacterial strains is crucial for the biological conversion of CO2 and potential CO2 mitigation to challenge global warming. To overcome the economic barriers, the production of value-added chemicals was desired by compensating for the overall processing cost. Here, we engineered cyanobacteria for photosynthetic squalene production and cultivated them in a scalable photobioreactor using industrial flue gas. First, an inducer-free gene expression system was developed for the cyanobacteria to lower production const. Then, the recombinant cyanobacteria were cultivated in a closed photobioreactor (100 L) using flue gas (5% CO2) as the sole carbon source under natural sunlight as the only energy source. Seasonal light intensities and temperatures were analyzed along with cyanobacterial cell growth and squalene production in August and October 2019. As a result, the effective irradiation hours were the most critical factor for the large-scale cultivation of cyanobacteria.
