Depression is the most prevalent mental disorder in pregnancy, and yet it is lessstudied than postpartum depression despite the consequences it may have onboth the pregnant woman and her offspring. Therefore, it would be important toknow which risk factors may favour the appearance of antenatal depression inorder to carry out appropriate prevention interventions. The aim of the presentreview was to identify the main risk factors of antenatal depression. We searchedin databases Pubmed and PsycINFO for articles published about the factorsassociated with antenatal depression from January 2010 through December *** literature review identified three main groups of antenatal depression riskfactors: sociodemographic, obstetric, and psychological. First, among thesociodemographic variables, the low level of studies and the economic incomeclearly stood out from the rest. Then, not having planned the pregnancy was themain obstetric variable, and finally, the main psychological risk factors werehaving a history of psychological disorders and/or depression as well aspresenting anxiety, stress, and/or low social support during pregnancy. Thisreview shows that the antenatal depression is affected by multiple factors. mostcan be identified at the beginning of the pregnancy, and some are risk factorspotentially modifiable through appropriate interventions, such as psychologicalfactors. For this reason, it is important to carry out a good screening for depressionduring pregnancy and consequently, be able to prevent its appearance ortreat it if necessary.

Cure characteristics of hydroxyl terminated polybutadiene (HTPB) prepolymer with avariety of blocked toluene diisocyanate (TDI) in the presence of triethylamine (TEA) andchloroacetic acid catalyst are reported. Phenol, thiophenol, p-chloropheno1, p-nitrophenol,p-cresol, resorcinol, naphthols, caprolactam and butylated-hydroxytoluene were used as blockingagents. viscosity measurements have been carried out using a mixture of HTPB and blocked TDIin cyclohexanone in the presence of the catalysts at 50℃ and 60℃ using Haake rotational vis-cometer. viscosity measurements have also been carried out with 50% solids such as ammonium sulphate along with HTPB and TDI adduct.

Controlled release of TDI and hence the cure characteristics of several blocked TDI with HTPB are reported. The reactions were followed through viscosity measurements as a function of time and temperature under the catalytic influence of triethylamine. The effect of nature of substituents present on the end capping substrate, temperature, solvent, basicity of catalyst and kinetics thereon have been studied.

Using the skyrme energy density formalism, a pocket formula is introduced for barrier heights and positions of 95 fusion reactions(48≤ZPZT≤1520) with respect to the charge and mass numbers of the interacting nuclei. It is shown that the parameterized values of RBand vBare able to reproduce the corresponding experimental data with good accuracy. moreover, the absolute errors of our formulas are less than those obtained using the analytical parametrization forms of the fusion barrier based on the proximity versions. The ability of the parameterized forms of the barrier heights and its positions to reproduce the experimental data of the fusion cross section have been analyzed using the Wong model.

The two-ponding depth （TPD） analysis procedure of single-ring infiltrometer data can yield invalid results, i.e., negative values of the field-saturated soil hydraulic conductivity or the matric flux potential, denoting failure of the two-level run. The objective of this study was to test the performance of the TPD procedure in analyzing the single-ring infiltrometer data of different types of soils. A field investigation carried out in western Sici]y, Italy, yielded higher failure rates （40%） in two clay loam soils than in a sandy loam soil （25%）. A similar result, i.e., fine-textured soils yielding higher failure rates than the coarse-textured one, was obtained using numerically simulated infiltration rates. Soil heterogeneity and reading errors were suggested to be factors determining invalid results in the field. With the numerical data, allowing a less generic definition of soil heterogeneity, invalid TPD results were occasionally obtained with the simultaneous occurrence of a high random variation （standard deviation ≥ 0.5） and a well developed structural correlation for saturated hydraulic conductivity （correlation length 〉 20 cm）. It was concluded that a larger number of replicated runs should be planned to characterize fine-textured soils, where the risk to obtain invalid results is relatively high. Large rings should be used since they appeared more appropriate than the small ones to capture and average soil heterogeneity. Numerical simulation appeared suitable for developing improved strategies of soil characterization for an area of interest, which should also take into account macropore effects.

In this paper, we present a new computational approach for solving an internal optimal control problem, which is governed by a linear parabolic partial differential equation. Our approach is to approximate the PDE problem by a nonhomogeneous ordinary differential equation system in higher dimension. Then, the homogeneous part of ODES is solved using semigroup theory. In the next step, the convergence of this approach is verified by means of Toeplitz matrix. In the rest of the paper, the optimal control problem is solved by utilizing the solution of homogeneous part. Finally, a numerical example is given.
