Authors: Gots V.I. , Rudenko I.I. , Lastivka O.V. , Volinska E.V. 
Published: October 2017

Досліджений вплив поверхнево-активних речовин зазначених типів у складі КД на початок витривалості, тривалість періоду індукції та міцність лужного цементу з вмістом доменної гранули (далі - шлак) від 50 до 100 % у складі алюмосилікатного компонента. При заміщенні лужного компонента метасилікатом натрію тривалість індукційного періоду істотно не змінюється. Проте, при збільшенні кількості шлаку до 88 - 100% і відповідному збільшенні вмісту лужного компонента в цементі, знижується ефективність аніонного поверхнево-активного речовини, що супроводжується зменшенням тривалості індукції період до 0,5 годин. Однак незалежно від вмісту шлакового компонента, типу і потоку лужної компоненти в цементі, введення добавок того ж типу, але інша структура - у формі оксиетиленових жирних спиртів і циклічних - визначає зниження міцність цементу. Ефективність поверхнево-активної речовини, з урахуванням характеру основної речовини для періодів витривалості, тривалості індукційного періоду та міцності цементного каменю на основі варіації шлако-портландцементу залежить від вмісту лужного компонента, який визначається співвідношенням між клінкером та шлаком у складі цементу. Згідно з визначеними показниками, ефективність аніонних поверхнево-активних речовин у складі комплексної добавки зменшується, а роль катіонних та неіногенних поверхнево-активних речовин підвищується.

<p><em>S</em><em>ex determination </em><em>in turtle species </em><em>is not only based on genotype, but also rely on the incubation temperature. In addition, sexual differentiation takes place during the thermo-sensitive period (TSP). This study was conducted to determine the effects of incubation temperature on </em><em>sex </em><em>expression profile of determination gene, bioreproduction, </em><em> phenotype</em><em>, and locomotory performances of olive ridley turtle hatchlings. Fertile eggs incubated at two temperatures, namely feminine temperature (30-33°C), and masculine temperature (26-27°C). Value of cycle threshold (C<sub>T</sub>) measured during TSP, i.e 23-25 embryonic development stage, and after TSP, i.e 26-27 embryonic development stage using real time PCR techniques. Comparison of gene expression at both incubation temperatures were analyzed by ANOVA, and Student’s t test. Hatchling bioreproduction and phenotype measurement consist of the incubation period, embryo growth, morphometrics, and locomotori performances hatchlings were analyzed with regression analysis and Student’s t test. The results showed expression of both aromatase and Rspond 1 genes (which plays a role in ovarian differentiation) after the TSP that incubated at feminine temperature higher and different with masculine temperature. In conjunction with the bioreproduction and phenotype, the incubation period of feminine temperature shorter than that of masculine. Likewise, growth of the embryo of feminine temperature was faster than that of masculine. Incubation at feminine temperature significantly affect to carapace width, length and width of the plastron, long flippers and rear arms, long neck, and the frequency of the swing flippers.</em><em> </em></p> <strong><em>Keywords: </em></strong><em>thermo-sensitive period (TSP), gene expression, phenotype, Lepidochelys olivacea</em>
