A Comparative Survey of Female Figures in Persian Miniatures: Studying Form, Color and Content of Miniatures by Moein Mosaver and Hosein Behzad

Moein Mosaver and Hosein Behzad depicted beauty in the form of female figures using their unique ways of applying form, color, and content. The purpose of the present research was to study the way female figures are drawn in works of Mosaver and Behzad, compare them, and find out the relationship between them to finally answer the main research question, which concerns finding the similarities and differences between the works of both artists in form, color, and content. The method of the research was qualitative, the way the data was processed was descriptive-analytic, and the information was gathered through library sources. Regarding the time gap between the lives of saver and Behzad, it seems there should be similarities and differences between their miniatures. The results of the research showed that the composition in the works of both artists is mostly vertical and centralized, and the primary color blue and the secondary colors green, purple, and orange are mostly used. Foreign influences and the impact of the economic conditions are obvious in their works. Some of the differences between their works are the application of more primary and warm colors in Mosaver’s works and less variety of color in Behzad’s, while the latter’s lines are freer. Behzad also used perspective in his miniatures, and he preferred content over form

Seroepidemiology of rubella, measles, HBV, HCV and B19 virus within women in child bearing ages (Saravan City of Sistan and Bloochastan Province)

Present survey basically focused on women between 15-45 years of age resident in a town of Sistan and Baluchistan province named as Saravan city located in border of Pakistan-Iran in order to find out the seropositivity against the viruses in child bearing ages in the above stated under study community. This descriptive cross-sectional study was carried-out from 2001 up to 2002. Saravan town was divided into 4 geographical areas and each area was further sub-divided into 10 blocks and in each block 10 families were chosen randomly. In the next step by referring to each family from the chosen married women with specified age i.e., 15-45 years, 5 mL blood was collected. Serum was then separated and stored at -20°C before the assay. ELISA kit was employed to detect anti B19, anti rubella, anti measles, anti HBV and anti HCV antibody. Furthermore during samples collection a questionnaire filled for each woman under study. This study showed that 89.6% of women understudy were seropositive against measles, rubella (96.2%), B19 (59.2%), HCV (0.8%) and HBV (19.8%), respectively. According to the results of no serious problem with rubella in this area; But, about measles, the present immunity against measles in this area is insufficient. It seems that incidence of B19 infection in this region is same as other places in Iran. The rate of seropositivity against HBV and HCV indicated of these viruses circulating in the population in this area. © 2007 Academic Journals

Hydrophobic Interactions and Dewetting between Plates with Hydrophobic and Hydrophilic Domains

We study by molecular dynamics simulations the wetting/dewetting transition and the dependence of the free energy on distance between plates that contain both hydrophobic and hydrophilic particles. We show that dewetting and strength of hydrophobic interaction is very sensitive to the distribution of hydrophobic and hydrophilic domains. In particular, we find that plates characterized by a large domain of hydrophobic sites induce a dewetting transition and an attractive solvent-induced interaction. On the other hand, a homogeneous distribution of the hydrophobic and hydrophilic particles on the plates prevents the dewetting transition and produces a repulsive solvent-induced interaction. We also present results for a kind of Janus interface in which one plate consists of hydrophobic particles and the other of hydrophilic particles showing that the inter-plate gap remains wet until steric constraints at small separations eject the water molecules. Our results indicate that the Cassie equation, for the contact angle of a heterogeneous plate, can not be used to predict the critical distance of dewetting. These results indicate that hydrophobic interactions between nanoscale surfaces with strong large length-scale hydrophobicity can be highly cooperative and thus they argue against additivity of the hydrophobic interactions between different surface domains in these cases. These findings are pertinent to certain protein-protein interactions where additivity is commonly assumed.Comment: 28 pages, 6 figure

The using of gibberellic acid hormone on cotton mature embryo resulted by crossing between wild and commercial species on artificial medium

The wild species of cotton have important role in cotton breeding due to their favorable traits, which include pest and disease resistance, drought tolerance, fiber quality and male cytoplasmic sterility. Transferring these favorable genes from wild species to commercial cultivars of cotton by the traditional methods or classical plant breeding procedure will be very difficult and impossible. This is due to the following: Confronting disordering in flower structure, the problems involved in cotton flower pollens germination in stigma level and destruction of embryo and endosperm in different stages of evolution. The first sign of these problems is the falling of ovary. Therefore, the first and important barrier in crossing between diploid and tetraploid cotton species is the inability of hybrid seeds to produce. Solving of these problems can be the first step in hybridizations programs. The artificial control of fertilization by the gibberellic acid (GA3) after crossing and hybrid embryo culture in the media will increase probability of hybrid plants production. In this study, three species named Sahel (tetraploid), Hashemabad (diploid) and Kashmar (diploid) were used. The parental species were planted on six plots and crosses were made between them. It must be noticed that we used Sahel species as paternal and the two diploid species as maternal species. As the study continues, two investigations were separately done on hybrids. Firstly, it consisted of using different amount of Gibberellic acid after pollination for the maintenance of bolls and secondly, 45 days embryos of all the crosses combined were cultured on liquid and solid M.S media. The results show that when hormone was not used, the amount of bolls that fell was 100%, but when Gibberellic acid was applied at 100ppm concentration, there was considerable differentiation in maintenance of bolls. The Hashemabad cultivar created bolls more than Kashmar but the percentage of seeds inside the bolls was so lower than Kashmar cultivar. In comparison between parents used and their hybrids, the latter's response was better. Also among the different media culture, it is seen that the growth of mature embryo in the liquid media was better than solid.Key word: Cotton, diploid species, tetraploid species, hybrid, media culture

Strings-to-rings transition and antiparallel dipole alignment in two-dimensional methanols

Structural order emerging in the liquid state necessitates a critical degree of anisotropy of the molecules. For example, liquid crystals and Langmuir monolayers require rod- or disc-shaped and long-chain amphiphilic molecules, respectively, to break the isotropic symmetry of liquids. In this Letter we present results from molecular dynamics simulations demonstrating that in two-dimensional liquids, a significantly smaller degree of anisotropy is sufficient to allow structural organization. In fact, the condensed phase of the smallest amphiphilic molecule, methanol, confined between two, or adsorbed on, graphene sheets forms a monolayer characterized by long chains of molecules. Intrachain interactions are dominated by hydrogen bonds, whereas interchain interactions are dispersive. Upon a decrease in density toward a gaslike state, these strings are transformed into rings. The two-dimensional liquid phase of methanol undergoes another transition upon cooling; in this case, the order–disorder transition is characterized by a low-temperature phase in which the hydrogen bond dipoles of neighboring strings adopt an antiparallel orientation

Quantum memory assisted entropic uncertainty and entanglement dynamics: Two qubits coupled with local fields and Ornstein Uhlenbeck noise

Entropic uncertainty and entanglement are two distinct aspects of quantum mechanical procedures. To estimate entropic uncertainty relations, entropies are used: the greater the entropy bound, the less effective the quantum operations and entanglement are. In this regard, we analyze the entropic uncertainty, entropic uncertainty lower bound, and concurrence dynamics in two non-interacting qubits. The exposure of two qubits is studied in two different qubit-noise configurations, namely, common qubit-noise and independent qubit-noise interactions. To include the noisy effects of the local external fields, a Gaussian Ornstein Uhlenbeck process is considered. We show that the rise in entropic uncertainty gives rise to the disentanglement in the two-qubit Werner type state and both are directly proportional. Depending on the parameters adjustment and the number of environments coupled, different classical environments have varying capacities to induce entropic uncertainty and disentanglement in quantum systems. The entanglement is shown to be vulnerable to current external fields; however, by employing the ideal parameter ranges we provided, prolonged entanglement retention while preventing entropic uncertainty growth can be achieved. Besides, we have also analyzed the intrinsic behavior of the classical fields towards two-qubit entanglement without any imperfection with respect to different parameter

A Note on Distance-Based Entropy of Dendrimers

This paper introduces a variant of entropy measures based on vertex eccentricity and applies it to all graphs representing the isomers of octane. Taking into account the vertex degree as well (degree-ecc-entropy), we find a good correlation with the acentric factor of octane isomers. In particular, we compute the degree-ecc-entropy for three classes of dendrimer graphs
