this study focuses on jane austens representation of her heroines in two of her novels: pride and prejudice, and mansfield park. i have concentrated only on a single idea: how jane austen takes her heroines through a course of psychogical reformation to which almost everything else in her novel is subsidiary. although i have discussed only pride and prejudice, we can trace austens carefully pla...
conclusions ti is an important parameter to consider in the relationship between si and nanoparticle concentrations. an increase in ti leads to a decrease in the range of linearity. results the results indicate that si depended on the concentration of nanoparticles and ti. in addition, si increased by increasing the tis ranging from 200 to 400 ms for all studied concentrations. the linear relat...
This study aims to analyze the relationship between perceived organizational culture (POC) and turnover intentions (TI) if this is mediated by support (POS) job insecurity (JI). For purpose, following hypotheses were formulated: (1) POC (support, goals, innovation, rules) has a negative significant with TI; (2) positive POS (affective cognitive); (3) cognitive) (4) JI; (5) JI (6) both represent...
abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
Comparison among Mechanical Properties of Investment-Cast c.p. Ti, Ti-6Al-7Nb and Ti-15Mo-1Bi Alloys
The present study compares castability and mechanical performance among alloys of c.p. Ti, Ti-6Al-7Nb and a newly-developed Ti-15Mo-1Bi in regard to their as-cast state. Experimental results indicate that average cast length of Ti-6Al-7Nb appears a little lower than c.p. Ti and Ti-15Mo-1Bi, although the differences are not significant. C.p. Ti has an hcp phase of lath-type morphology with serra...
High-energy density extreme ultraviolet radiation delivered by the FERMI seeded free-electron laser has been used to create an exotic nonequilibrium state of matter in a titanium sample characterized by a highly excited electron subsystem at temperatures in excess of 10 eV and a cold solid-density ion lattice. The obtained transient state has been investigated through ultrafast absorption spect...
thalassemia intermedia; folic acid and vitamin b12 supplementation. what we know and what is needed?
this study presented a mini review on folic acid deficiency and recommendations for its supplementation in thalassemia intermedia (ti). ti is a clinical condition which lies between thalassemia major and thalassemia minor. although ti patients may not need regular blood transfusion, precise diagnosis and management are critical for the prevention of clinical complications and quality of life im...
ti-mcm-41 was synthesized at ph 3, 7 and 11. the titanium content was determined by aas and found to be 4%, 3.2% and 4.5%, respectively. in order to increase the titanium content in ti-mcm-41, ti(iv) ions were grafted onto ti-mcm-41 using ticl4 in toluene and ti(obu)4 in ethanol. the incorporation of ti was determined to be 28% and 30%, respectively. the oxidation of olefins such as cyclopenten...
We report the fixing of photorefractive holographic gratings with high efficiency in a sample of K(1-y)Li(y)Ta(1-x)Nb(x)O(3) doped with Cu, V, and Ti. Holograms are thermally fixed through the screening of a photorefractive space-charge f ield by a nonphotoactive species at elevated temperatures. Fixed holograms are revealed by illumination at lower temperatures. Diffraction efficiencies of 25%...
Anodic fast-growth of highly ordered hexagonal arrays of TiO2 nanotubes by a single anodization step
Highly-ordered TiO2 nanotubes (NTs) have gained much importance for application in hydrogen production by water splitting (photoelectrochemical cells) and the dye-sensitized solar cells (DSCs) [1,2]. The TiO2 NTs can be synthesized using a titanium foil in fluoride containing electrolytes via electrochemical anodization method. The NTs geometry depends on different anodizing parameters (electro...
