    The 8^8B Neutrino Spectrum

    Full text link
    Knowledge of the energy spectrum of 8^8B neutrinos is an important ingredient for interpreting experiments that detect energetic neutrinos from the Sun. The neutrino spectrum deviates from the allowed approximation because of the broad alpha-unstable 8^8Be final state and recoil order corrections to the beta decay. We have measured the total energy of the alpha particles emitted following the beta decay of 8^8B. The measured spectrum is inconsistent with some previous measurements, in particular with a recent experiment of comparable precision. The beta decay strength function for the transition from 8^8B to the accessible excitation energies in 8^8Be is fit to the alpha energy spectrum using the R-matrix approach. Both the positron and neutrino energy spectra, corrected for recoil order effects, are constructed from the strength function. The positron spectrum is in good agreement with a previous direct measurement. The neutrino spectrum disagrees with previous experiments, particularly for neutrino energies above 12 MeV.Comment: 15 pages, 13 figures, 4 tables, submitted to Phys. Rev. C, typos correcte

    Evaluation of cancer incidence in a certain area is one of the most important components of cancer control. From 1993 to 2012, a 1.4-fold increase in the annual number of new cancer cases among the population of Siberia and the Far East was registered. The age-standardized incidence rates are increasing with aging of the population. For all cancers, cancer incidence is higher in men than in women with the exception of thyroid and skin melanoma cancer incidence. Six types of cancer incidence curves have been identified: 1) reduction; 2) high growth; 3) relatively uniform growth; 4) reduction followed by stabilization; 5) growth followed by stabilization; 6) relatively uniform increase, then a significant increase.ΠžΡ†Π΅Π½ΠΊΠ° заболСваСмости злокачСствСнными новообразованиями Π½Π° ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½Π½ΠΎΠΉ Ρ‚Π΅Ρ€Ρ€ΠΈΡ‚ΠΎΡ€ΠΈΠΈ являСтся ΠΎΠ΄Π½ΠΎΠΉ ΠΈΠ· Π²Π°ΠΆΠ½Π΅ΠΉΡˆΠΈΡ… ΡΠΎΡΡ‚Π°Π²Π»ΡΡŽΡ‰ΠΈΡ… ΠΏΡ€ΠΎΡ‚ΠΈΠ²ΠΎΡ€Π°ΠΊΠΎΠ²ΠΎΠΉ Π±ΠΎΡ€ΡŒΠ±Ρ‹.

    Results of epidemiological study on kidney cancer incidence among the population of the Primorsky Krai are presented. Methods of mathematical statistics recommended by the Ministry of Public Health were used. Within the first 5 years of the period 1994 to 2008, thekidney cancer incidence rate increased from 8,3 0/0000 to 12,5 0/0000 in men and from 4,4 0/0000 to 6,6 0/0000 in women, being the 8th most common cancer in men and the 11th most common cancer in women. The highest incidence rate was observed at the age of 55–59 years. The kidney cancer incidence rate in children for the period 1994–2008 was 1,8 0/0000, reaching peak incidence at age 0–4. Kidney cancer is the third most common cancer following hemoblastosis and brain tumors in children of this age group.ΠŸΡ€Π΅Π΄ΡΡ‚Π°Π²Π»Π΅Π½Ρ‹ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ эпидСмиологичСского исслСдования заболСваСмости Ρ€Π°ΠΊΠΎΠΌ ΠΏΠΎΡ‡ΠΊΠΈ насСлСния ΠŸΡ€ΠΈΠΌΠΎΡ€ΡΠΊΠΎΠ³ΠΎ края с ΡƒΡ‡Π΅Ρ‚ΠΎΠΌ возраста ΠΈ ΠΏΠΎΠ»Π°.

    A cancer incidence in general and in its separate nosologic forms (stomach cancer, liver cancer, cancer of lung, skin cancer, breast cancer, cervical cancer, prostate cancer, thyroid gland cancer and hemoblastosis cancer) has been studied in the population of Tomsk and Tomsk region within 1990β€”2001 taking into account ages and sexes. The dynamics of the cancer incidence in general and in separate forms of malignant neoplasms has been cited and the prognosis of this process up to 2007 has been done.
