1. The algorithm chosen in this study is a simplified and slightly modified version of Wagners model which is one of the models presented in Reference 1.
2. As a starting point of the investigation the algorithms developed in the paper were exercised in various models.
3. All works called for the specifications should be executed by the contractor.
4. The transverse supporting members are located within the distance predetermined by the design,
5. Some very complicated models are investigated in the paper.
6. Every line in the body, as defined above, remains unchanged in direction.
7. The method recommended was used by the chemist.
8. If heated the ice melts.
9. The charged body brought near the uncharged one will produce an induced charge in that object.
10. Condensation occurs when the air becomes supersaturated.
11. The motors produced are of the latest design.
12. Pavement built of local materials and of industrial waste product is very cheap.
13. The sub base reduces the required thickness of the pavement base.
14. Bituminous macadam is a broken-stone and gravel surfacing treated with organic binders.
15. When burned gas is mixed with the oxygen.
16. Saturated steam has the same temperature at different pressures.
17. When saturated steam has the same temperature at different pressures.
18. The most commonly used building materials are steel, concrete, stone, wood and brick.
19. The materials used in building construction must be durable and fire-resistant.
20. Concrete combined with steel reinforcement is called reinforced concrete.
21. The students spoken about at the meeting yesterday completed this work successfully.
22. The terms of delivery provided for in the contract were not fulfilled by the sellers.
23. The data so far obtained were of no interest at all.
24. The price insisted upon during negotiations was rather high.
25. The smaller stone used on the surface gave better riding qualities, and the smaller broken pieces became tightened by the constant passage of vehicles.
