Effect of Addition of Plastic in Bituminous Mixes Prepared with Modified Bitumen

The present study deal with the utilization of PET waste in Bituminous Concrete prepared with modified bitumen. The detailed analysis will be carried out to assess the physical and strength characteristic of prepared BC mix as per the Indian Standards. Modified bitumen used is CRMB -55 which is a binder obtained from the recycling of rubber tyre. Modified bitumen is temperature susceptible and also increases the fatigue life of pavement under the heavy traffic load. The study involved in the evaluation of more than one modification in bituminous mixes such as CRMB -55 is itself modified binder while modification has been done in the aggregate blend by addition of plastic. However, a combination has not yet been tried. The Marshall Stability test was performed to assess strength characteristics. The Marshall Stability values increase with the amount of PET and maximum stability was obtained at 6% by weight of the binder. The considerable increment was observed in Stability value with PET 6% dosage as 18.99%.

Deficiencies in Silicone Impression for Crowns and Bridges

There are many steps in fabrication of dental crowns and bridges at which an error can occur, and a technician can only fabricate a quality restoration if the impression itself is of adequate quality. All dental practitioners should have the ability to evaluate the quality of dental impression before sending to the laboratory. Elastomeric silicones (polysiloxane) are the most utilised impression materials in dental practice. The present study deal with the deficiencies of silicones dental impressions sent to commercial dental laboratories for fabrication of single crowns and bridges.

Deshumanización y destino en las narrativas bélicas de Joseph Heller y Norman Mailer: Coincidencias entre Match-22 y The Nacked and the Dead

ResumenLa segunda guerra mundial y los años posteriores a la misma dieron paso a un nuevo orden mundial en el que las personas, a merced de una alienante maquinaria social, experimentaron un progresivo deterioro de sus rasgos humanos. Las dos novelas estudiadas en el presente artículo abordan esta temática desde perspectivas distintas, pero con abundantes rasgos en común. Catch-22 utiliza fórmulas humorísticas y satíricas, mientras que The Naked and the Dead emplea un tono más sobrio y solemne. En dichas obras destacan los ambientes mecanicistas que anulan al ser humano, junto a la inexorable acción del destino o la fatalidad.Palabras clave: Joseph Heller, Norman Mailer, guerra, deshumanización, mecanicismo, entropía, destino.AbstractWorld War II and its aftermath gave way to a new world order and a mechanised society in which people progressively began losing both their human and humane traits. The two novels considered in the present study deal with these matters from different general viewpoints, but revealing several common features as well. Catch-22 uses humour and satire in its approach, whereas The Naked and the Dead adopts a more refl ective discourse of solemnity. Both works refer to mechanised environments that nullify human condition and render it insignifi cant, as they also focus on the element of destiny or fate.Key words: Joseph Heller, Norman Mailer, war, dehumanisation, mechanistic, entropy, destiny.

SELECTION IN REFERENCE TO BIOLOGICAL GROUPS. V. ANALYSIS OF FULL-SIB GROUPS

ABSTRACT Previous studies in this series have dealt with the consequences of truncation selection operating with respect to random groups within which geno-full-sib group structure. The objective is to compare the results of individual and group selection as these methods operate on populations of random versus typic interaction may exist. The present study deal with a non-random, full-sib groups. In almost all comparisons individual selection is found to be qualitatively and quantitatively superior when used in conjunction with full-sib groups. This is due to the fact that the change in gene frequency for full-sib groups is a function of both direct and associate effects, whereas with random groups it is a function of direct effects only. With regard to group selection the efficiency is invariably superior when selection operates on non-random, full-sib rather than random groups.
