the objective of this study was to examine the effects of the fluidized-bed drying me-thod on the final quality of two varieties of iranian rice, medium- and long grain. the re-sults were compared to that of paddy drying using a traditional method. rough rice was treated in the fluidized bed drier at 140ºc for 2 minutes. similar samples were dried for 8-10 hrs by the traditional method. dried s...

Sun exposure in both childhood and adult life represents the main environmental risk determinant for cutaneous melanoma. However, little is known about the joint effects of sun exposure during early and later life on melanoma risk. A case-control study in Belgium, Germany and France conducted in 1991-1992 suggests that the melanoma risks attached to indicators related to sun exposure appear to ...

The Sun encompasses planet Earth, supplies the heat that warms it, and even shakes it. The United Nation’s Intergovernmental Panel on Climate Change (IPCC) assumed that solar influence on Earth’s climate is limited to changes in solar irradiance and adopted the consensus opinion of a hydrogen-filled Sun—the Standard Solar Model (SSM). They did not consider the alternative solar model and instea...

In this paper, we prove a few lemmas concerning Fibonacci numbers modulo primes and provide a few statements that are equivalent to Wall-Sun-Sun Prime Conjecture. Further, we investigate the conjecture through heuristic arguments and propose a couple of additional conjectures for future research.

High performance computers are analysed using simple MPI, OpenMP and mixed mode Game of Life codes. Direct comparison between the HPC 3500 and HPC 6500 is used to approximate the operating system overhead present, and it is found that operating system uses up to 5% of the machine’s processing power. Vast performance increases are discovered when using OpenMP on the HPC 6500, which are due to ca...

SUN-domain proteins belong to a gene family including classical Cter-SUN and mid-SUN subfamilies differentiated by the position of the SUN domain within the protein. Although present in animal and plant species, mid-SUN proteins have so far remained poorly described. Here, we used a combination of genetics, yeast two-hybrid and in planta transient expression methods to better characterize the S...

The ability of animals to learn to use the sun for orientation has been explored in numerous species. In birds, there is conflicting evidence about the experience needed for sun compass orientation to develop. The prevailing hypothesis is that birds need entire daytime exposure to the arc of the sun to use the sun as an orientation cue. However, there is also some evidence indicating that, even...

BACKGROUND First-degree relatives of melanoma survivors have a substantially higher lifetime risk for melanoma than individuals with no family history. Exposure to ultraviolet radiation (UVR) is the primary modifiable risk factor for the disease. Reducing UV exposure through sun protection may be particularly important for children with a parental history of melanoma. Nonetheless, limited prior...
