The design and manufacture of the vehicle structure determines of the safety and suitability during operation. For most designers, the bearing capacity of the vehicle body is not completely understood. The initial estimate of the vehicle is simply a uniform simply supported overhang beam structure. With the development of computer technology, people can use more complex and closer to the actual body computational model, but it generally requires a lot of work, and designers are often only able to see the final result. It is not clear that the factors affect Load-carrying properties of the body structure. Designers often can not look find a process of improving the design. This method to scan the body structure by a computer calculation and analysis, the geometry, mechanical properties of parameters of the body cross-section has been plotted map. You can quickly and accurately understand the overall performance of the body, analysis the performance difference of different body cross-section. Reasonableness and balance of the body can be measured and awarded. In general, it is very important for the designer of the vehicle.

In this study, 121Sb (α, n) 124I reaction, which is one of the production reactions of the 124I radioisotope, which has an important use in nuclear medicine, was investigated. Experimental value EXFOR was obtained and theoretical data was obtained using TALYS 1.8 and NON-SMOKER half-experimental cross section values were calculated using theoretical data and experimental values. In addition, the Astrophysical S-factor was calculated. The obtained results were compared with EXFOR data.

Results of obtaining of 186Re for nuclear medicine using 13 MeV deuterons were presented. Cross section and yield of 186W(d,2n)186Re reaction were experimentally measured in the deuterons energy range from the threshold up to 13 MeV. The total yield of 186Re in the energy range 12.5/6.43 MeV from natural tungsten was measured as (2.3 ± 0.15) MBq/(uA·h). The yield of the 186Re from enriched 186W for deuteron energy 12.5 MeV was evaluated as (8.2 ± 0.13)MBq/(uA·h). Possibility of 186Re obtaining in sufficient quantities for a radiopharmaceuticals synthesis was established. On the basis of data on the yield 186Re it is confidently expected that using of Tomsk Polytechnic University cyclotron can produce enough amount of 186Re for using in nuclear medicine

Abstract Nuclear nanomedicine forms a new research field based on the synergy of nuclear medicine and nanotechnology and implying the use of nanomaterials as carriers of diagnostic or therapeutic radionuclides. Such an approach promises a series of advantages over classical methods of nuclear medicine, including an increased surface area-to-volume ratio, passive/active delivery, high loading capacity, large cross-section in interactions with biological tissues, and unique properties of nanomaterials that make possible many functionalities within one construct. In this short review article, we will highlight our recent achievements in the development of nuclear nanomedicine technologies, which promise the advancement of methods for cancer treatment.

AbstractThe photoabsorption spectra of the carbon ions have been obtained by using two laser-produced plasmas. The photoionization cross-section of the CV has been absolutely measured and the value at threshold, σ=(4.7±0.5) × 10−19cm2, as well as its behaviour at higher energies agrees quite well with the theoretical calculations.

High resolution dark field microscopy is becoming an important tool for the investigation of unstained and specifically stained biological molecules. Of primary consideration to the microscopist is the interpretation of image Intensities and the effects of radiation damage to the specimen. Ignoring inelastic scattering, the image intensity is directly related to the collected elastic scattering cross section, σɳ, which is the product of the total elastic cross section, σ and the eficiency of the microscope system at imaging these electrons, η. The number of potentially bond damaging events resulting from the beam exposure required to reduce the effect of quantum noise in the image to a given level is proportional to 1/η. We wish to compare η in three dark field systems.
