investigations were initiated this year to develop field and laboratory viability assays for stored walnut pollen, indentify conditions suitable for in vitro pollen germination and pollen tube growth, and determine pollen tube growth rates in pistillate flowers. Results of this project will provide background information for future investigations of transmission of pollen-borne virus, factors i...

Testes size often predicts the winner during episodes of sperm competition. However, little is known about the source of nutrients allocated to testes development, or testes plasticity under varying nutrient availability. Among many holometabolous insects, metabolic resources can derive from the larval or adult diet. Distinguishing the source of nutrients allocated to testes can shed light on l...

Opting an appropriate dietary regime has been and will be one of the simplest ways of providing health for and preventing disorders of human beings. Cardiovascular diseases-one of the most prevalent causes of morbidity and mortality worldwide-are in particular related to diet. Atherosclerosis, the most common pathogenic process of cardiovascular disease, is closely connected with food ingredien...

Three-dimensional models built for the peanut Ara h 2 allergen and other structurally-related 2S albumin allergens of dietary nuts exhibited an overall three-dimensional fold stabilized by disulphide bridges well conserved among all the members of the 2S albumin superfamily. Conformational analysis of the linear IgE-binding epitopes mapped on the molecular surface of Ara h 2 showed no structura...

An analysis of genetic structure and differentiation in cultivated walnut (Juglans regia) using 15 microsatellite loci revealed a considerable amount of genetic variation with a mild genetic structure indicating five genetic groups corresponding to the centers of diversity within the home range of walnut in Eurasia. Despite the narrow genetic differentiation among groups accounting for only 10 ...

Nowadays, application of high speed crafts with large tonnage is of our country's essences. In order to gain high speed, new multi hull crafts are traditional. A hull form having been used recently in frigates is the Trimaran. Trimaran hull form and motion have been extensively studied due to the development of numerical and analytical methods as well as the exploitation of experimental setup. ...

The objective of this study was to evaluate total phenolic content and antioxidant activity of leaf and different parts of fruit (hull, shell, and kernel) of Bene in Ilam province. Total phenolic content was determined with the Folin- Ciocalteu Reagent (FCR); antioxidant activity of methanolic extracts were examined by DPPH (2,2diphenyl- 1- picrylhydrazyl), FRAP (ferric reducing antioxidant pow...

We present a nonstandard hull construction for locally uniform groups in a spirit similar to Luxembourg’s construction of the nonstandard hull of a uniform space. Our nonstandard hull is a local group rather than a global group. We investigate how this construction varies as one changes the family of pseudometrics used to construct the hull. We use the nonstandard hull construction to give a no...

Simulation can be used to visualize the mechanical classification of walnuts. It collect microscopic information about walnuts in roller and guide its optimization design. In this process, simulation parameters are essential factors that ensure effectiveness simulation. study, crucial thin-skinned walnut particles were determined by combining discrete element method (DEM) physical tests. Firstl...
