The use of water steam at distillation of hydrocarbon mixes results in negative consequences. There are proved the perspective method of process of primary distillation oil and gas condensate raw materials. There are defined mass-change characteristics of process of rectification at use of alternative steaming agents and their comparisons with indicators of traditionally applied steaming agent are done.

The aim of the study was to investigate tensile strength of 3 soft silicone elstomers: A-soft line 30, Elite Super Soft, Bosworth Dentusil and to compare them with the results of investigation of Ufi Gel SC.48 samples were prepared - 12 of each material. The sample consisted of two parts: 20 mm long and 4 mm in diameter acrylic cylinder, and 20 mm long and 4 mm in diameter silicone cylinder. Both parts of the sample were connected with glue prepared by the manufacturer. Investigation of the tensile strength of the materials A-soft line 20, Elite Super Soft, Bosworth Dentusil was carried out on a testing machine Houndfield H5KS model THE S/N D83281and investigation of the tensile strength of Ufi Gel SC was carried out using a testing machine FPZ 10/1.The average value of the tensile strength of A-soft line 30 was 9,63 N, of Bosworth Dentusil - 7.50 N and that of Elite Super Soft - 7.29 N, while that of Ufi Gel SC was 18.61 N.Ufi Gel SC is characterised by the best tensile strength, followed by A-soft line 30, Bosworth Dentusil and Elite Super Soft. Each of the estimated material can be used in prosthodontic treatment in patients, depending on the necessity of relieving the prosthetic base.
本研究的目的是研究3种软硅树脂的抗拉强度:A-soft line 30, Elite Super soft, Bosworth Dentusil，并将其与Ufi Gel sc的研究结果进行比较。每种材料制备48个样品- 12个。样品由两部分组成:长20毫米、直径4毫米的丙烯酸圆柱体和长20毫米、直径4毫米的硅胶圆柱体。样品的两个部分都用厂家配制的胶水连接。在Houndfield H5KS型号the S/N d83281试验机上对a - Soft line 20、Elite Super Soft、Bosworth Dentusil材料的拉伸强度进行了研究，在FPZ 10/1试验机上对Ufi Gel SC材料的拉伸强度进行了研究。A-soft line 30的抗拉强度平均值为9.63 N, Bosworth Dentusil - 7.50 N和Elite Super Soft - 7.29 N, Ufi Gel SC的抗拉强度平均值为18.61 N, Ufi Gel SC的抗拉强度最好，A-soft line 30、Bosworth Dentusil和Elite Super Soft的抗拉强度依次为。每一种估计的材料都可以用于患者的修复治疗，这取决于解除义肢基座的必要性。

Tribological properties of nickel titanium-based alloys were investigated systematically. One binary (Ni60Ti40) and two ternary (Ni58.8Ti39.2Al2, Ni57Ti38Al5) alloys were fabricated using a conventional sintering process. Their friction and wear properties were studied using a reciprocating dry sliding method against 440C steel at temperatures up to 200 degrees C. The results showed that the addition of aluminium reduced the friction coefficient of Ni60Ti40 alloy and increased its wear resistance at all test temperatures. The results obtained were related to microstructure of the alloys and their wear mechanisms. Wear surface of the alloys were characterised mainly by smearing indicating that adhesion was the dominant mechanism governing the friction and wear behaviour of the alloys. At elevated temperature, the area of smearing layer became more visible.
