This work shows that despite a lattice mismatch of almost 20%, CdMnTe/CdTe/CdMnTe heterostructures grown directly on Si(111) have surprisingly good optical emission properties. The investigated structures were grown by molecular beam epitaxy and characterized by scanning transmission electron microscopy, macro-and micro-photoluminescence. low temperature macro-photoluminescence experiments indicate three emission bands which depend on the CdTe layer thickness and have different confinement characteristics. Temperature measurements reveal that the lower energy emission band (at 1.48 eV)is associated to defects and bound exciton states, while the main emission at 1.61 eV has a weak 2D character and the higher energy one at 1.71 eV has a well-defined (zero-dimensional, 0D) 0D nature. Micro-photoluminescence measurements show the existence of sharp and strongly circularly polarized (up to 40%) emission lines which can be related to the presence of Mn in the heterostructure. This result opens the possibility of producing photon sources with the typical spin control of the diluted magnetic semiconductors using the low-cost silicon technology.

Annual forage legumes are important components of livestock production systems in East Texas and the southeastern US. Forage legumes contribute nitrogen (n) to cropping systems through biological n fixation, and their seasonal biomass production can be managed to complement forage grasses. Our research objectives were to evaluate both warm- and cool-season annual forage legumes as green manure for biomass, n content, ability to enhance soil organic carbon (SOC) and soil n, and impact on post season forage grass crops. nine warm-season forage legumes (WSl) were spring planted and incorporated as green manure in the fall. Forage rye (Secale cereale l.) was planted following the incorporation of WSl treatments. Eight cool-season forage legumes (CSl) were fall planted in previously fallow plots and incorporated as green manure in late spring. Sorghum-sudangrass (Sorghum bicolor x Sorghum bicolor var. sudanense) was planted over all treatments in early summer after forage rye harvest and incorporation of CSl treatments. Sorghum-sudangrass was harvested in June, August and September, and treatments were evaluated for dry matter and n concentration. Soil cores were taken from each plot, split into depths of 0 to 15, 15 to 30 and 30 to 60 cm, and soil C and n were measured using combustion analysis. nylon mesh bags containing plant samples were buried at 15 cm and used to evaluate decomposition rate of above ground legume biomass, including change in C and n concentrations. Mungbean (Vigna radiata l. [Wilczek]) had the highest shoot biomass yield (6.24 t DM ha-1) and contributed the most total n (167 kg∙ha-1) and total C (3043 kg∙ha-1) of the WSl tested. Decomposition rate of WSl biomass was rapid in the first 10 weeks and very slow afterward. Winter pea (Pisum sativum l. spp. sativum), arrow leaf clover (Trifolium vesiculosum Savi.), and crimson clover (Trifolium incarnatum l.) were the most productive CSl in this trial.

Before the advent of cheap, synthetic fertilizers, legumes were commonly used as green manure crops for their ability to fix atmospheric nitrogen (n). A three-year study at Overton, TX examined legume integration into high-biomass sorghum (Sorghum bicolor l.) production systems on a lilbert loamy fine sand recently cultivated after a fertilized bermudagrass [Cynodon dactylon (l.) Pers.] pasture. In this split-split plot design, ‘Dixie’ crimson clover (Trifolium incarnatum l.) and ‘Iron and Clay’ cowpea (Vigna unguiculata l.) were integrated into a high-biomass sorghum production system to evaluate impacts on n concentration, C concentration, and yield of high-biomass sorghum and their impacts on soil total n and soil organic carbon (SOC). Main plots were split into crimson clover green manure (ClGM) and winter fallow (FAll) followed by three sub-plots split into warm-season crop rotations: cowpea green manure (CPGM), cowpea-sorghum intercrop (CPSR), and sorghum monocrop (SORG). Three n fertilizer treatments (0, 45, 90 kg n∙ha−1) were randomized and applied as sub-sub plots. The ClGM increased (P sorghum biomass yield (16.5 t DM∙ha−1) 28% in year three but had no effect in the first two years. The CPSR treatment reduced sorghum yield up to 62% compared to SORG;whereas CPGM increased sorghum yield 56% and 18% the two years following cowpea incorporation. Rate of n fertilizer had no effect on sorghum biomass yield. Decrease in SOC and soil n over time indicated mineralization of organic n and may explain why no n fertilizer response was observed in sorghum biomass yield. Cowpea showed strong potential as a green manure crop but proved to be too competitive for successful intercropping in high-biomass sorghum production systems.

Background: The protective role of (poly)phenols against metabolic disorders has been extensively studied in adults but not in ***: To assess associations of dietary (poly)phenols and their subclasses with cardiometabolic health parameters in adolescents. Methods: A cross-sectional study was conducted in 944 individuals aged 11 to 14 years enrolled in the SI! Program for Secondary Schools trial (nCT03504059). (Poly)phenol intake was assessed using semi-quantitative food frequency questionnaires and the Phenol-Explorer database. The measured cardiometabolic parameters were waist circumference (WC) age-sex z-score， blood pressure (BP) age-sex z-score， blood glucose (BG)， triglycerides (TG)， and high-density lipoprotein cholesterol (HDl-c). Multilevel mixed-effect linear regression models were applied to examine the association between (poly)phenol quintiles and cardiometabolic health ***: Compared to the lowest quintile， adolescents in the highest quintile of total (poly)phenol intake had lower WC z-scores (β=-0.09， 95%CI=-0.09;-0.08， P-for trend=0.002)， mean arterial pressure z-scores (β =-0.11， 95%CI=-0.12;-0.09， P-for trend=0.206)， and HDl-c (β=-1.52， 95%CI=-2.90;-0.14， P-for trend=0.108)， after multivariable adjustment. The WC z-scores (β=-0.11， 95%CI=-0.19;-0.03， P-for trend=0.013) and HDl-c (β=-2.16， 95%CI=-3.78;-0.53， P-for trend=0.046) were lower in the highest quintile of flavonoid intake compared to the lowest quintile. The highest quintile of phenolic acid intake was associated with a lower WC z-score (β=-0.14， 95%CI=-0.26;-0.02， P-for trend=0.011) and TG levels (β=-8.83， 95%CI=-12.37;-5.30， P-for trend nd the highest quintile of stilbene intake with lower BG (β=-1.83， 95%CI= -3.103;-0.64， P-for trend nd TG (β=-3.22， 95%CI= -4.95;-1.49， P-for trend=0.034)， and with higher HDl-c (β=2.328， 95%CI= 1.40;3.17， P-for trend=0.466) compared to the lowest quintile.

The central minimum, maximum, and astigmatic simulated keratometry（K） and anterior axial power values were determined. Spherical and cylindrical mean power diopters were obtained at the central and at the steepest point of the cornea both on anterior and on posterior mean power maps. Pachymetry evaluations were taken at the center and paracentrally in the 3 mm zone from the center at a location of every 45 degrees. Receiver operating characteristic（ROC） analysis was used to determine the best cut-off values and to evaluate the utility of the measured parameters in identifying patients with ***： The minimum, maximum and astigmatic simulated K readings were 44.80±3.06 D, 47.17±3.67 D and 2.42±1.84 D respectively in keratoconus patients and these values differed significantly（P〈0.0001 for all comparisons） from healthy subjects. For all pachymetry measurements and for anterior and posterior mean power values significant differences were found between the two groups. Moreover, anterior central cylindrical power had the best discrimination ability（area under the ROC curve=0.948）.COnClUSIOn： The results suggest that scanning-slit topography and pachymetry are accurate methods both for keratoconus screening and for confirmation of the diagnosis.
