We apply the method of the magnetic structure function (MSF), S(τ ) = 〈|b(t + τ ) − b(t)|n〉 ∝ τ ζ (n), to analyze the scaling of solar wind turbulence over the range from 1 s to 104 s. By sorting the fluctuations according to the direction of the local mean magnetic field, we obtain a second-order structure function in (r, Θ) coordinates that reveals the scale-dependent anisotropy of the power spectrum. The scale-dependent anisotropy of the MSF indicates that the fluctuation energy tends to cascade toward the direction perpendicular to the local field. The dependence of the MSF scaling index ζ on the direction of the local field is found to be similar to that reported in Horbury et al. and Podesta, with ζ⊥ = 0.53 ± 0.18 and ζ‖ = 1.00 ± 0.14. Furthermore, we estimate and find the scaling law between the perpendicular and parallel scales r‖ ∝ r0.614 ⊥ , which implies the elongation along the parallel direction as the turbulence eddy evolves toward the small lengthscales. These results are in agreement with the predictions of magnetohydrodynamic turbulence theory.","PeriodicalId":383544,"journal":{"name":"Wahrscheinlichkeitsrechnung und Mathematische Statistik","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1970-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114570370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the ways to increase its concentration in plants is biofortification through various agronomic practices including artificial lighting. The aim of the study was to determine the responses of baby leaf lettuce to various Se content in hydroponic solution at different ratio of blue (B) and red (R) light of light-emitting diodes (LED) lighting. Lettuce (Lactuca sativa, ‘Little Gem’) were grown hydroponically under B:R light ratios 10%B:90%R, 75%B:25%R. The photon flux density (PFD), photoperiod, temperature, and relative humidity in the growth chamber were maintained at 220 mol m-2 s-1, 18 h, 21/17±2C, and 60±5%, respectively. Two experiments with Se were performed using natrium selenate (Na2SeO4). Results of the first experiment (Se 0, 1, 3 ppm) showed that the content of Se in lettuce was about 15 times higher at 3 ppm compared to 1 ppm. Similar trends were observed for both B and R ratios. However, even the lowest dose of Se in hydroponic solution inhibited lettuce growth and reduced photosynthesis and chlorophyll content. Therefore, a second experiment was performed with lower Se doses (0, 0.5, 1 ppm) at different growth stages (11th and 17th days after sowing (DAS)). It was found that when Se exposure was initiated at the 17thDAS, the lettuce accumulated a lower content of Se compared to the 11th DAS, but this did not have a negative effect on their growth. The B:R ratio of 10B:90R% resulted in a higher content of Se in the leaves. Overall, these results suggest that properly composed doses of Se, LED lighting and application time could be suitable way for cultivation of selenium-biofortified baby leaf lettuces without any adverse effects on growth.","PeriodicalId":383544,"journal":{"name":"Wahrscheinlichkeitsrechnung und Mathematische Statistik","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1970-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115007403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
