Since, he knew how to penetrate the Chakravyuha, but did not know how to exit from it during the time of danger contributed to his death.

Since neutrons are electrically neutral, they penetrate matter more deeply than electrically charged particles of comparable kinetic energy ; therefore they are valuable probes of bulk properties.

Since then, non-invasive methods – which penetrate the body nonetheless, but by electromagnetic or particle radiation rather than a scalpel – have continuously enlarged the scope of medical technology.

Since the police handguns could not penetrate the bank robbers ' body armor, the patrol officers ' bullets were ineffective.

Since T. duellica can penetrate regular human skin on normal occasions, the effects of agatoxin are more likely to be felt by the victim.

Since this is where the armed gangs take their kidnap victims, the police's ability to penetrate the area even for such a short time was seen as a sign of progress.

Since the chigoe flea technically has no reservoir species and the female will cause tungiasis to any mammalian organism it can penetrate, this means the flea will have a relatively large amount of hosts and victims.

Since the 18th century, the German language became more important, starting to penetrate Slavic dialects.

Since he introduces so much modern music, I could not resist asking how he felt about it.

Since more is known about Quiney than about any other acquaintance of Shakespeare in Stratford, his career may be followed to its sudden end in 1602.

Since little is known about autism, and almost nothing has been written for the layman, we'd like to share one experienced mother's comments.

Since her bereavement this individual has reported to the writer on numerous occasions about how helpful the class discussions were to her in this adjustment crisis.

Since the A.L.A.M. holdings embraced only about twenty-five per cent of motor vehicle patents, the denial of rights to independent companies did not retard technical progress in unlicensed sectors of the industry.

Since the difference between the U. S. and International acre is only about a quarter of the size of an A4 sheet of paper ( 0. 016 square metres, 160 square centimetres or 24. 8 square inches ), it is usually not important which one is being discussed.

Since about 2005, computer scientists have attempted to develop automated methods to infer aesthetic quality of images.

Since about 2001, territorial defence forces, which as of 2002 number around 150, 000, have been forming, organized into battalions, companies, and platoons spread across Belarus.

Since the Persian force obviously contained a high proportion of missile troops, a static defensive position would have made little sense for the Athenians ; the strength of the hoplite was in the melee, and the sooner that could be brought about, the better, from the Athenian point of view.

Since about 2005, Oi Polloi ( from Scotland ) have recorded in Scottish Gaelic.

Since 1987 the Congress operates in the port city of Valparaíso, about 110 kilometers (~ 70 mi.

Since most people, and most cultures, substantially agree about most pure ethical situations, casuistry often creates ethical arguments that can persuade people of different ethnic, religious and philosophical beliefs to treat particular cases in the same ways.

Since that time, the rate of crater production on Earth has been considerably lower, but it is appreciable nonetheless ; Earth experiences from one to three impacts large enough to produce a 20 km diameter crater about once every million years on average.

Since people are human, one should teach first about humans, not machines or techniques.

Since history and memory ( representations of or belief about the past ) are distinct in all philosophy and ontology from plan, vision or intent ( representations of or will to change the future ), statements that confuse these are category errors: No statement about history or memory can imply a similar statement about a plan or vision or intent, nor vice versa-a distinction sometimes credited to Hume who distinguished also the morality of a statement from its truth.
