Paschold, Helmut W. Vibration in the occupational and general environmental settings can be manifested in many ways according to frequency, magnitude, or medium and subsequent effects on the human body. Frequency ranges with potential risk to humans can range from less than one cycle per second Hertz - Hz to hundreds of thousands. The vibration ranges to be considered are Whole Body Vibration ranging from 0. Both WBV and noise are acknowledged as having potential to causing harm to the human body. Safety and health SH professionals address hazards through anticipation, recognition, evaluation, and control. The anticipation and recognition of noise hazards can be considered a basic skill set among SH professionals.

Сюда. В этой встрече было что-то нереальное - нечто, заставившее снова напрячься все его нервные клетки. Он поймал себя на том, что непроизвольно пятится от незнакомцев. Тот, что был пониже ростом, смерил его холодным взглядом. - Сюда, мистер Беккер. Быстрее. Беккер повернулся и побежал, но успел сделать только один шаг.

 Может быть, я так и сделаю. - Mala suerte, - вздохнул лейтенант.  - Не судьба. Собор закрыт до утренней мессы. - Тогда в другой .

 - Мидж, - взмолился он, - я знаю, что ты терпеть не можешь Стратмора, но… - Это не имеет никакого значения! - вспылила.  - Первым делом нам нужно убедиться, что Стратмор действительно обошел систему Сквозь строй. А потом мы позвоним директору.

Стратмор, в свою очередь, тоже сгорал от нетерпения, но подругой причине. Если Дэвид и дальше задержится, придется послать ему на помощь кого-то из полевых агентов АНБ, а это было связано с риском, которого коммандер всеми силами хотел избежать. - Коммандер, - сказал Чатрукьян, - я уверен, что нам надо проверить… - Подождите минутку, - сказал Стратмор в трубку, извинившись перед собеседником. Он прикрыл микрофон телефона рукой и гневно посмотрел на своего молодого сотрудника.

Беккер склонился над. - Вам плохо. Клушар едва заметно кивнул: - Просто… я переволновался, наверное.  - И замолчал.

Сьюзан - это единственное, что не позволит Стратмору меня уничтожить. - Сьюзан, - сказал он, волоча ее к лестнице, - уходи со. Клянусь, что я тебя пальцем не трону. Сьюзан пыталась вырваться из его рук, и он понял, что его ждут новые проблемы. Если даже он каким-то образом откроет лифт и спустится на нем вместе со Сьюзан, она попытается вырваться, как только они окажутся на улице.

ГЛАВНАЯ РАЗНИЦА МЕЖДУ ЭЛЕМЕНТАМИ, ОТВЕТСТВЕННЫМИ ЗА ХИРОСИМУ И НАГАСАКИ Соши размышляла вслух: - Элементы, ответственные за Хиросиму и Нагасаки… Пёрл-Харбор. Отказ Хирохито… - Нам нужно число, - повторял Джабба, - а не политические теории. Мы говорим о математике, а не об истории.

Может быть, ключ связан с количеством человеческих жертв, оценочной суммой нанесенного ущерба в долларах… - Она замолчала, снова вчитываясь в текст.  - Слово разница особенно важно. Главная разница между Хиросимой и Нагасаки.
