Abstract

Knowing the exchangeable sodium percentage (ESP) variations and its values in sodic or saline-sodic soils is essential in order to estimate the amount of soil amendments and better land management. ESP calculated from cation exchange capacity (CEC), and since CEC measurement is difficult and time-consuming, ESP computation is costly and subject to error. Thus, presenting a method to estimate ESP indirectly, by an easily available index is much more efficient and economical. In this study, 296 soil samples collected and analyzed from Sistan plain, southeastern Iran. Soil ESP were predicted by using artificial neural networks, comprising radial basis functions (RBFN) and multilayer perceptron (MLP) and adaptive neuro-fuzzy inference systems (ANFIS), and results compared with stepwise linear regression method. Results indicated that the linear regression models performed poorly in order to estimate ESP (R2 ≤ 0.58 and root mean square error (RMSE) ≥ 4.31). Applying fewer inputs (electrical conductivity (EC) and pH), ANFIS showed better results (R2=0.80, RMSE=2.34), while increasing inputs (clay and organic carbon) decreased the accuracy (R2=0.82, RMSE=4.20). Using more inputs, RBFN resulted in better performance in comparison with other methods (R2=0.83, RMSE=2.85). Sensitivity analysis using the connection weight method demonstrated that EC, pH, clay percentage and bulk density are the most important variables in order to explain ESP variability in the region, respectively. Generally, considering the evaluation criteria and the number of used variables of models, ANFIS (with EC and pH as inputs) is the most appropriate method for estimating ESP in Sistan plain.

Abstract

Stochastic Programming is an asset for the next world researchers due to its uncertainty calculations, which has been skipped in deterministic world experiments as it includes complicated calculations. Two-stage stochastic programming concerns two time period decisions based on some random parameters obtained from past experience or some sort of survey. The objective function for formulating two-stage stochastic programming with fixed recourse includes two parts: first-stage forecast and second-stage fixed decisions based on the experiment results. The constraints are similar to the normal optimization techniques rather some adjustments of requirements and technology assets. The fixed recourse decisions are sort of decisions from the deterministic world. Formulation techniques of two-stage stochastic programming with fixed recourse may be used for further complications arises in stochastic programming like complete recourse problems, multi-stage problems, etc. And that’s why Two-stage stochastic programming with fixed recourse is called the primary model for stochastic programming.

Abstract

Child malnutrition is one cause of death worldwide, but the greatest burden is borne by African countries, particularly in Sub-Saharan Africa. The Democratic Republic of Congo, despite its wealth of biodiversity, is confronted with this phenomenon which seriously hinders its development. A cross-sectional descriptive study was conducted in The Nord Ubangi Province from 01 to 31 December 2016 on a population of 133 malnourished children aged 0 to 5. The results show that the 2 to 3 year old age group (25-36 months) was the most affected by malnutrition. The most affected children were male, at 52.63%. Most of these children, 24.8%, resided in rural areas around Gbadolite. The majority of their parents, 61.6%, was farmers or only engaged in housework. 78.9% of respondents had edema in their bodies, and 91.7% did not meet the appetite test. These children were subjected to antibacterial treatment outside of ready-to-use therapeutic foods (ATPE). After this treatment, the cure rate was satisfactory at 73.6%.

Abstract

Background:Iron deficiency anemia is one of the most common hypochromic microcytic anemias and nutritional disorders in today’s world. Vitamin D is an important steroid hormone for the metabolism of serum calcium and phosphorus and plays a major role in the function of various body systems. Evidence suggests that vitamin D deficiency is associated with iron deficiency anemia. We aimed to compare the serum level of vitamin D between children with iron deficiency anemia and healthy ones. Methods: This case-control study was conducted on 60 patients with iron deficiency anemia and 60 healthy ones who did not suffer from iron deficiency anemia. Patients participated in the study voluntarily. Vitamin D levels were measured using HPLC and ferritin by RIA method. To estimate the predictive value of vitamin D levels in iron deficiency anemia, ROC curve analysis was used. Results: In this study, 120 children aged 6-144 months with mean age of 30.2±31.4 months were analyzed; 49.2% of them were boys and 50.8% were girls. Vitamin D levels varied from 4.8 to 63.2 ng/ml with a mean of 23.87±12.57 ng/ml in all patients (19.25±9.15 ng/ml in the case group and 28.48±13.84 ng/ml in the control group (P<0.001). In other words, patients with a vitamin D level <23.6 ng/ml should be investigated for iron deficiency anemia, and sufficient vitamin D had a protective effect on iron deficiency anemia and each unit increase in vitamin D decreased the chance of iron deficiency anemia by 7.8%. Conclusion: The prevalence of simultaneous iron deficiency anemia and vitamin D deficiency is very high in children and there is a significant relationship between serum levels of 25(OH)D and hemoglobin.

Abstract

Sickle cell disease is a genetic disease linked to the presence of hemoglobin S in the blood and is a major public health problem in Africa. The drugs available are expensive in view of the purchasing power of the majority of the population. The aim of this study was to assess the clinical efficacy of an improved traditional medicine called Drepanoalpha (an anti-sickle cell polyherbal formula) in a homozygous sickle patient using the quantum magnetic resonance analyzer. The results show the relevance of the use of this unconventional technical approach in the sickle cell disease patient treatment evaluation. Indeed, this study showed that Drepanoalpha is effective in vivo and restored homeostatic balance by optimizing some vital functions in the treated patient. The quantum magnetic resonance analyzer is therefore an important away which allows understanding the disorders of the body due to sickle cell disease and their correction post-treatment. It is desirable that the use of this device be validated in the evaluation of the effectiveness of anti-sickling drugs in large-scale clinical trials in rural areas like Nord-Ubangi province. Indeed, this instrument is not only fast, practical, economical, accessible, non-invasive but also easy to use and suitable for this category of research in underprivileged areas. The results obtained are in perfect agreement with the facts observed (recovery of some vital parameters and disappearance of seizures in the patient).
