Introduction: Machines are devices that convert energy into work or in some cases, one form of work into another. Heat engines are machines that convert heat energy into mechanical work. In order for a heat engine to perform it must have a working substance, such as a gas or liquid that must absorb heat energy, perform work and discard the remaining energy that cannot be transformed into work.

Могу я поинтересоваться, кто со мной говорит. - А-а… Зигмунд Шмидт, - с трудом нашелся Беккер. - Кто вам дал наш номер. - La Guia Telefonica - желтые страницы. - Да, сэр, мы внесены туда как агентство сопровождения.

Несколько месяцев она добивалась, чтобы он объяснил, что это значит, но Дэвид молчал. Моя любовь без воска. Это было его местью. Она посвятила Дэвида в некоторые секреты криптографии и, желая держать его в состоянии полной готовности к неожиданностям, посылала ему записки, зашифрованные не слишком сложным образом. Список необходимых покупок, любовные признания - все приходило к нему в зашифрованном виде.

 Вот что нам надо сделать.  - Стратмор начал спокойно излагать свой план.  - Мы сотрем всю переписку Хейла с Танкадо, уничтожим записи о том, что я обошел систему фильтров, все диагнозы Чатрукьяна относительно ТРАНСТЕКСТА, все данные о работе компьютера над Цифровой крепостью, одним словом -. Цифровая крепость исчезнет бесследно. Словно ее никогда не .

Еще одна спираль. Ему все время казалось, что Беккер совсем рядом, за углом. Одним глазом он следил за тенью, другим - за ступенями под ногами. Вдруг Халохоту показалось, что тень Беккера как бы споткнулась.

Джабба повернул голову к экрану ВР. Атакующие линии рвались вперед, они находились уже на волосок от пятой, и последней, стены, Последние минуты существования банка данных истекали. Сьюзан отгородилась от царившего вокруг хаоса, снова и снова перечитывая послание Танкадо. PRIME DIFFERENCE BETWEEN ELEMENTS RESPONSIBLE FOR HIROSHIMA AND NAGASAKI ГЛАВНАЯ РАЗНИЦА МЕЖДУ ЭЛЕМЕНТАМИ, ОТВЕТСТВЕННЫМИ ЗА ХИРОСИМУ И НАГАСАКИ - Это даже не вопрос! - крикнул Бринкерхофф.  - Какой же может быть ответ.

 Я серьезно. Рано или поздно я отсюда смоюсь. - Я этого не переживу.

 Никаких. Продолжай движение. ГЛАВА 78 Джабба обливался потом перед спутанными проводами: он все еще лежал на спине, зажав в зубах портативный фонарик. Ему было не привыкать работать допоздна даже по уикэндам; именно эти сравнительно спокойные часы в АНБ, как правило, были единственным временем, когда он мог заниматься обслуживанием компьютерной техники.

 Определенно. - Так вы успели его рассмотреть. - Господи.

    During a cyclic process, a heat engine absorbs J of heat from a hot reservoir, does work and ejects an amount of heat J into the surroundings cold reservoir.
