Abstract The aim of this work is to investigate the structural features, physicochemical, rheological, and emulsifying properties pectin extracted from pumpkin “ Cucurbita maxima ” pulp peel. After peel fresh were solubilized in water at high temperature (80°C) clarification, obtained filtrate was treated with aluminum sulphate, which precipitates a fibrous coagulum. results found that major fu...

Background: RNA plays key role in many aspects of biological processes and its tertiary structure is critical for its biological function. RNA secondary structure represents various significant portions of RNA tertiary structure. Since the biological function of RNA is concluded indirectly from its primary structure, it would be important to analyze the relations between the RNA sequences and t...

to study the causes of difficulties in understanding the german short story bypersian learners from the perspective of text linguistics first we have searchedthe factors of cohesion and coherence in german texts in a short story. then wehave checked its translations by the students and observed that these people arefamiliar with the grammatical structure of each sentence and the vocabulary ofth...

the main diatomic structure-forming species of the zayandehrud reservoir was investigated by collecting samples from the surface, five, seven and 10 m depths from january 2011 to october 2012 along four linear transects. asterionella formosa hassall, cyclotella ocellata pantocsek and fragilaria crotonensis kitton were revealed as the three structure-forming species among diatomic algae in the r...

in this work, the optimization calculations were carried out on quetiapine hemifumarat, 4, and its analogues, 1-5. these calculations were carried out using the b3lyp/6-31g(d) level of theory. the dft calculations clarified a boat structure for dibenzothiazepine moiety of the molecule which piperazine moiety has a chair conformation. thermal energies (e), enthalpies (h), and free energies (g) o...
