Transmission electron microscopy of interfaces in structural ceramic composites
(Blackwell Science LTD, 1999)
Ceramic composites based either on a particulate, fibre or a lamellar architecture are potentially useful as damage-tolerant high-temperature engineering materials. The ability of the interfaces in such systems to deflect ...
Synthesis of some 5-methoxy-3-[(benzazole-2-yl)thioacetylamino]-2,3-dihydrobenzofuran derivatives and study of their antihypertensive activity [SYNTHESE DE CERTAINS DERIVES DE METHOXY-5 [(BENZAZOLE-2-YL)THIOACETYLAMINO]-3 DIHYDRO-2,3 BENZOFURANE ET RECHERCHE D'ACTIVITE ANTIHYPERTENSIVE]
(1994)
In this study, some 5-methoxy-3-[(benzazole-2-yl) thioacetylamino]2,3-dihydrobenzofuran derivatives were synthesized and their structures were elucidated by IR, NMR and microanalyses. The antihypertensive activities of the ...

New approach for determining the coefficient of consolidation, Cv, for normally consolidated kaolinite clay
(International Society Offshore& Polar Engineers, 1998)
in this study, the coefficient of consolidation of kaolinite clay is determined using a newly developed test system. The results of these experiments are compared with results obtained from the conventional oedometer test ...
Regresyon analizinde çoklu bağıntı sorununun (multicollinearity) incelenmesi ve uygulanması
(1996)
Bir regresyon analizinde araştırmacılar çoklu bağıntı (multicollinearity) sorunu ile çok sık karşılaşmaktadırlar. Açıklayıcı değişkenlerden bir veya birkaçının diğer açıklayıcı değişkenler tarafından iyi açıklandığı zaman, ...
Hidrojen depolayıcısı olarak zeolit

Günümüzde hayat standardının yükselmesi ile, endüstrinin her alanında etkin bir şekilde kullanılabilecek temiz, ucuz ve tükenmez enerji kaynağı arayışı son derece önem kazanmıştır. Bu enerji arayışına önerilen en güçlü ...
Some new 4-aryl-2-thiazolylhydrazones
(1997)
In this study, three series of 4-aryl-2-thiazolylhydrazones were synthesized using three different thiosemicarbazones. Structures of the compounds were elucidated by IR, 1H NMR and elemental analysis. The prepared compounds ...
?ݧ Sialon Transformation in Calcium-containing ? -SiAlON Ceramics
(1999)
Recent studies on rare earth densified ?-sialon ceramics have shown that the resulting ?-sialon product, present either as a single phase or in conjunction with ß-sialon, is unstable when heat treated at lower (1350-1600°C) ...
