Ученые предлагают использовать лазеры для строительства дорог на Луне

Очевидно, что будущим лунным колонистам потребуются хорошие дороги, поскольку поверхность нашего естественного спутника весьма неровная и к тому же покрыта толстым слоем пыли. Группа американских и европейских исследователей предлагает решить проблему прокладки лунных дорог с помощью мощных лазеров.

Предлагаемый лазер состоит из зеркал и линзообразных устройств, концентрирующих солнечный свет, который позволяет расплавлять пыль и превращать ее в стеклообразное вещество. После этого расплавленной массе будет придаваться определенная форма, оптимальная для дорожного покрытия.

Исследователи успешно протестировали данную технологию на грунте, по составу напоминающем лунный, с помощью 12-киловаттного углекислотного лазера. Предполагается, что «дорожные» лазеры будут доставляться на Луну участниками миссий.

  1. Girls treated with testosterone for breast most cancers require monitoring for
    indicators of virilization. The root cause of gynecomastia is hormonal, ensuing from
    an imbalance of androgenic and estrogenic motion on breast
    tissue (201). More particularly, gynecomastia results
    from an absolute or relative deficiency of androgenic, or absolute or relative extra of estrogenic, motion on breast tissue.
    A variety of conditions that affect the degrees or actions of these intercourse

    If bloating or water retention turns into extreme, customers ought to lower the dose or discontinue use.

    Alternatively, trenbolone is an alternative possibility
    for skilled users because it doesn’t aromatize.
    Due to Dianabol’s aromatization effects and
    being extremely estrogenic, it’s a compound that causes important
    amounts of water retention. This can go away customers trying puffy, bloated, and smooth-looking; therefore, why it’s
    sometimes used in the low season.
    Many individuals who use anabolic steroids are aware of the risks of taking them,
    and believe that by taking the medicine in certain ways they will keep
    away from unwanted aspect effects. Or they could take additional medicines to attempt to counter the unwanted side
    effects. In fact, testosterone, by binding to AR, produces an increased manufacturing of IGF-1, a decreased expression of myostatin and the differentiation of pluripotent mesenchymal cells into a myogenic
    lineage. Flowchart of constructive and unfavorable effects of
    anabolic-androgenic steroid (AAS) administration. Prolonged and high doses of testosterone and his derivatives lead to severe consequences in all body tissues and organs.
    Thereby, AASs results are the result of the amplification of testosterone
    and estrogens physiologic penalties.
    Average Doses Higher doses significantly increase the risk and severity of
    unwanted side effects. It is tough to estimate
    the prevalence of steroid misuse in the Usa because many nationwide surveys that ask about drug use do not include questions about steroids.
    Nevertheless, data on steroid misuse among young college students are available from the NIDA-supported Monitoring the Future Survey.
    But it’s usually found in smaller quantities, the place it’s
    used to maintain bones robust and sexual function healthy.

    From the steroid scandals that plagued major league baseball to the jokes that surround steroid

    them recuperate sooner from grueling workouts. I assume prioritizing short-term features over long-term health is a chance that may have
