Forecasting of monthly relative humidity in Delhi, India, using SARIMA and ANN models.

Relative humidity plays an important role in climate change and global warming, making it a research area of greater concern in recent decades. The present study attempted to implement seasonal autoregressive moving average (SARIMA) and artificial neural network (ANN) with multilayer perceptron (MLP) models to forecast the monthly relative humidity in Delhi, India during 2017-2025. The average monthly relative humidity data for the period 2000-2016 have been used to carry out the objectives of the proposed study. The forecast trend in relative humidity declines from 2017 to 2025. The accuracy of the models has been measured using root mean squared error (RMSE) and mean absolute error (MAE). The results showed that the SARIMA model provides the forecasted relative humidity with RMSE of 6.04 and MAE of 4.56. On the other hand, MLP model reported the forecasted relative humidity with RMSE of 4.65 and MAE of 3.42. This study concluded that the ANN model was more reliable for predicting relative humidity than SARIMA model.

Plasma lipids and lipoproteins in children and young adults with major ß-thalassemia from western Iran: influence of genotype.

To determine the plasma lipid and lipoprotein profiles and their possible association with the type of ß-thalassemia mutation we studied 103 major ß-thalassemia patients including 71 children and 32 young adults compared to 102 healthy subjects consisted of 90 children and 12 young healthy adults. The plasma lipid and lipoprotein levels were measured by conventional methods. Considering all of the patients the levels of total cholesterol (TC), LDL-cholesterol (LDL-C), and HDL-cholesterol (HDL-C) were significantly lower compared to controls. However, the level of TG was significantly higher in cases than controls. Comparing thalassemic patients homozygous for a ß0 type of mutation with those homozygous for a ß+ type of mutation (IVSI.110 G:A) indicated that the levels of LDL-C, TC were significantly increased and TG concentration tended to be higher in the latter patients. In conclusion, our study indicates that hemolytic stress results in hypocholesterolemia in major ß-thalassemia patients and the presence of more severe genotype in patients is correlated with more reduction in TG, TC, and LDL-C levels.

Effects of Zn rates and application forms on protein and some micronutrients accumulation in common bean (Phaseolus vulgaris L.).

In order to investigation the effects of Zn rates and application forms on protein and element contents (Fe, Cu, Mn, N and Zn) in bean plant, an experiment was conducted as a factorial based on completely randomized design at greenhouse conditions during 2006. Treatments were included zinc rates in 4 levels (10, 20, 30 and 40 mg Zn kg(-1) soil(-1) in ZnSO4 source) and 3 application forms (soil application, seed pelleting and foliar spraying). Results showed that Zn rates had significant effect on accumulation of Zn, Cu, Mn and N in bean leaves. Nitrogen accumulation in leaves reduced with increasing of zinc in the soil. Among Zn application forms, spray application had the highest accumulation of Fe, Zn and Mn in leaves (423.17, 282.89 and 88.17 mg kg(-1), respectively). The highest Zn content in seed was observed in 20 and 40 mg Zn kg(-1) soil(-1) levels (46.39 and 45.62 mg kg(-1), respectively). Meanwhile, all treatments of Zn (both rate and application) had not significant effects on Cu and Mn accumulation in bean seeds. According to interaction effects between Zn rates and application forms, the highest Fe content in seed was observed when 40 mg kg(-1) soil(-1) of Zn was applied as foliar spraying. The seed protein content nearly was stable while Zn levels was increased from 20 to 40 mg Zn kg(-1) soil(-1). Grain yield had significant correlation to zinc and Cu of leaves but, biomass had significant and negative correlation to Zn content of leaves at p < 0.05% probability levels.
