Critical Nitrogen Dilution Curve in Processing Potato Cultivars

American Journal of Plant Sciences 2015年第19期6卷 3144-3156页

作者： claudia marcela giletto Hernán Eduardo Echeverría Unidad Integrada FCA UNMdP-INTA Balcarce Argentina

The critical nitrogen dilution curve (CNDC) can be used as a diagnostic tool to assess crop N nutrition during the growing season. Potato cultivars have different biomass production and accumulation of N and consequently different growth patterns. These differences among cultivars may result in different CNDC. The aims were a) to determine the CNDC for different potato cultivars;b) to compare these curves with reference curves;and c) to assess the possibility of using the CNDC to estimate the N nutritional status of the crop. The biomass production and N concentration of shoots and tubers of potato cultivars Innovator, Gem Russet, Umatilla Russet, Bannock Russet and Markies Russet were measured. The harvest index (HI) and N harvest index (NHI) were determined. The coefficient a of the CNDC was similar among cultivars, while the coefficients b for Innovator and Gem Russet (-0.42 and -0.36, respectively) were smaller than those for the other cultivars (average -0.25). HI and NHI were greater in Innovator, smaller in Markies Russet, and intermediated in the other three cultivars. The coefficients b of the CNDC were correlated with HI and NHI (HI, r = -0.62, p < 0.0001 and -0.53, p < 0.0001;NHI, r = -0.60, p < 0.0001 and -0.61, p < 0.0001 for 2004/5 and 2005/6, respectively). The relationship between relative tuber yield (RY) and N nutrition index (NNI) was fit by a quadratic-plateau function. At similar situations of N deficiency, Innovator had lower yield and greater response to N rate than the other potato cultivars. The differences in HI and NHI among cultivars may explain the differences in the coefficient b of the CNDC. The NNI identified the status of N adequately in potato cultivars.

We compared resistance to decay, mold fungi, termites and insect larvae of particleboards incorporated with the raw boron minerals ulexite and colemanite to that of particleboards impregnated with the commercial boron preservative zinc borate, or boric acid plus a borax mixture. We also quantified water absorption, thickness swell and boron release of particleboards. Ulexite had the best decay resistance, and colemanite had the best termite resistance. However, ulexite and colemanite were not as effective as zinc borate or the boric acid/borax mixture in preventing mold growth. In general, the boric acid/borax mixture combination was more effective against Anobium larvae than the other treatments. Less boron was released by specimens containing zinc borate and colemanite than by those containing ulexite or the boric acid/borax mixture. In general, water absorption and thickness swell were similar among the different treatments, but both were slightly higher in the ulexite-incorporated specimens. Further mechanical tests will be needed to evaluate the particle- board properties and thereby the compatibility of these boron minerals with various manufacturing processes.

Ibuprofen-Maltodextrin Interaction: Study of Enantiomeric Recognition and Complex Characterization

引用

Pharmacology & Pharmacy 2013年第1期4卷 18-30页

作者： claudia Garnero Carolina Aloisio marcela Longhi Departamento de Farmacia Facultad de Ciencias Químicas Universidad Nacional de Córdoba Ciudad Universitaria Córdoba Argentina

The interaction between ibuprofen and maltodextrins with different dextrose equivalent was studied in solution and solid state in order to investigate the effect on the solubility of ibuprofen and to determine their usefulness in terms of chiral recognition. Apparent binding constants were calculated using nuclear magnetic resonance spectroscopy experiments and solubility studies. The results showed an increase in the apparent solubility of ibuprofen in the presence of maltodextrins that depended on their ionization state. The freeze-drying method was used to prepare solid complexes, while physical mixtures were obtained by simple blending. These solid systems were characterized in the solid state using differential scanning calorimetry, thermogravimetric analysis, Fourier Transform-Infrared spectroscopy, scanning electron microscopy and X-ray diffractometry. Detailed nuclear magnetic resonance studies provided evidence of the influence of the type and concentration of the maltodextrin host on the chiral recognition of racemic ibuprofen, indicating that these linear ligands act as chiral selectors.

Abatement of Helminth Eggs and Bacterial and Viral Indicators in Soil after Land Application of Treated Sludges

引用

Journal of Water Resource and Protection 2013年第12期5卷 1155-1164页

作者： claudia Campos Milena Beltrán marcela Duarte Luz Medina Francisco Lucena Juan Jofre 1Department of Microbiology University of Barcelona Barcelona Spain 2The Water Research Institute University of Barcelona Barcelona Spain Department of Microbiology Pontificia Universidad Javeriana Bogotá Colombia

The reduction of helminth eggs, fecal coliforms and somatic coliphages present in sewage sludge after treatments and abatement by application to soil was determined. Traditional stabilization processes produced small changes in the concentrations of the parameters studied. In contrast, thermal treatments and liming produced dramatic reductions. Fecal coliforms were the most affected by both types of treatments;somatic coliphages showed some persistence after 30 minutes at 60°C;and both somatic coliphages and helminth eggs showed some persistence to storage in quick lime. However, both treatments supplied biosolid suitable for unrestricted application in agriculture. Abatement in soils in the climatic conditions tested (mild to cold temperatures and high relative humidity) was slow and took several months to reach the background levels. These results suggest that environmental conditions (temperature and humidity) play the main role in inactivating the microorganisms, since abatement was similar in different soil types. The extended permanence of pathogens and microbial indicators in soil after the application of treated sludges indicates that, in the normal weather conditions of the areas where the study was performed and the amounts of sludges applied, contaminant microbes are not easily mobilized from the complex matrixes that constitute the treated sludges and that consequently in normal conditions their release as diffuse pollution is of lesser importance.

It has been documented that increased vegetable consumption is associated with preventive effects in some public health problems such as obesity and some chronic noncommunicable diseases. The aim of this study was to determine the association of nutritional status with vegetable consumption in adolescents from Technical High Schools in Mexico City. A sample of 2368 adolescents was obtained who were applied a questionnaire of frequency food consumption and anthropometric measurements were taken, the nutritional diagnosis was obtained with Who Anthro Plus program. The data obtained were analyzed with the statistical package SPSS version 20.0 for Windows Statistics®. When the correlation of frequency consumption of vegetables with nutritional status, in the final phase, It found that teens who never ate vegetables were more likely to develop obesity (36.0% GI and 36.10% GC), compared with teens who consumed daily (8.9% GI and 2.10% GC), existing difference highly significant. The teenagers of the Technical High School in Mexico City in the intervention group presented a basal daily intake of 15.7% and after the intervention their intake increased to 21.3%. With respect to the control group it started with a daily intake of 12.6% to 14.9% increasing it. An increase was achieved in the daily consumption of vegetables in adolescents of both groups so it is concluded that the intervention was successful.
