This study was designed to evaluate the effect of isthmus width on the strength of the remaining tooth structure in maxillary first premolars restored with class 2 silver amalgam restorations. One hundred ten sound maxillary first premolars freshly extracted as a part of orthodontic treatment were collected. The teeth were then divided into 10 groups of 11(More)
Extent of heterosis for seed yield is an indicator for transgressive segregation in cross of self-pollinated crops. However, the extent of heterosis is thought to be related to the genetic diversity among the parents. Isoenzymic variation was used for estimating the genetic diversity. Eight varieties of green gram (Vigna radiata) were characterized for(More)
Twenty six hexaploid triticale (X Triticosecale Wittmack) X bread wheat (Triticum aestivum L. em Thell) derivatives, along with 2 bread wheat and 2 triticale checks, were grown in normal and P-stress environments. Spikes/plant and grain yield/plant, followed by peduncle length, Were the most sensitive to phosphorus deficiency, which also caused a delay in(More)
Correlation coefficient analysis conducted on 22 triticale x bread wheat derivatives along with six checks to select true- breeding derivative(s) for future hybridization programme with tolerance to drought and cold stress conditions as well as better quality traits revealed significant correlation of grain yield with spikelets per spike, biological yield,(More)
Carbon–carbon (c/c) composites have low density, high stiffness and retain their properties at high temperature. The manufactured composite has significant internal damage like, voids, matrix cracking and debonding at interfaces due to the mismatch in thermal stresses induced during manufacturing process. Also there is some distortion of the cross-section(More)
