I^+ states of ^<26>Mg through the (α, ^3He) reaction at 81MeV

The ^Mg (α, ^3He) ^Mg reaction leading to seven 1^+ states, proposed previously by proton scattering at 201 MeV and by the (α, ^3He) reaction at 50MeV, was measured at E_α=80.9MeV. The cross sections obtained were analyzed within the framework of the exact-finite-range distorted wave Born approximation. The spectroscopic factors for a d_ transfer to 1^+ states were compared with those predicted by sd shell model calculations. Two of the 1^+ states were found to have a simple (d_d_) structure consistent with the shell model picture. Others with too large d_ transfer strength were ascribed owing to a mixture of other nearby states with J^π values other than 1^+ in referring to a recent compilation

移動手段としての階段利用の推奨が身体活動の強度および量に及ぼす影響 ―若年女性を対象とした予備的検討―

Physical activity is now a well-established key factor for the maintenance of good health and prevention of disease. The current physical activity guidelines recommend that an adult should invest at least 150 minutes（ 2 hours and 30 minutes） a week in moderate-intensity aerobic exercises or 75 minutes（ 1 hour and 15 minutes） a week in vigorous-intensity aerobic physical activity, or an equivalent combination of moderate- and vigorous-intensity aerobic activity. The purpose of this preliminary study was to examine the effect of using stairs related to the intensity level and the amount of physical activity in young women. To determine the amount and frequency of light-, moderate-, and vigorous-intensity physical activity and the duration of physical activity, the subjects were asked to wear an accelerometer （Lifecorder, Suzuken, Japan） for 2 days. We found that on the day when stairs were used the women recorded a significantly longer period of moderate-intensity physical activity and significantly higher total daily energy expenditure than on the day when elevators were used. There was no significant difference in the duration of light- and vigorous-intensity physical activity. These results indicate that compared to the use of elevators, the use of stairs results in greater daily energy expenditure and greater duration of moderate-intensity physical activity

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
