The European powers continued to pursue diplomatic avenues. The representatives of the four neutral Great Powersthe United Kingdom, France, Austria and Prussiamet in Vienna, where they drafted a note that they hoped would be acceptable to both the Russians and the Ottomans. The peace terms arrived at by the four powers at the Vienna Conference were delivered to the Russians by the Austrian Foreign Minister Count Karl von Buol on 5 December 1853. The note met with the approval of Nicholas I; however, Abdulmecid I rejected the proposal, feeling that the document's poor phrasing left it open to many different interpretations. The United Kingdom, France, and Austria united in proposing amendments to mollify the Sultan, but the court of St. Petersburg ignored their suggestions.:143 The UK and France then set aside the idea of continuing negotiations, but Austria and Prussia did not believe that the rejection of the proposed amendments justified the abandonment of the diplomatic process.

In what year did Count Karl von Buol deliver the Vienna Conference news to the Russians?

Maternal factors also play a role in the body's immune response. At birth, most of the immunoglobulin present is maternal IgG. Because IgM, IgD, IgE and IgA don't cross the placenta, they are almost undetectable at birth. Some IgA is provided by breast milk. These passively-acquired antibodies can protect the newborn for up to 18 months, but their response is usually short-lived and of low affinity. These antibodies can also produce a negative response. If a child is exposed to the antibody for a particular antigen before being exposed to the antigen itself then the child will produce a dampened response. Passively acquired maternal antibodies can suppress the antibody response to active immunization. Similarly the response of T-cells to vaccination differs in children compared to adults, and vaccines that induce Th1 responses in adults do not readily elicit these same responses in neonates. Between six to nine months after birth, a child's immune system begins to respond more strongly to glycoproteins, but there is usually no marked improvement in their response to polysaccharides until they are at least one year old. This can be the reason for distinct time frames found in vaccination schedules.

The difference in responses in infant immune systems is the cause of what?
Answer: distinct time frames found in vaccination schedules

In 2013 a lot of media coverage was given to unclassified NSA's study in Cryptologic Spectrum that concluded that Tito did not speak the language as a native, and had features of other Slavic languages (Russian and Polish). The hypothesis that "a non-Yugoslav, perhaps a Russian or a Pole" assumed Tito's identity was included. The report also notes Draza Mihailovic's impressions of Tito's Russian origins.

In what year did the study in Cryptologic Spectrum come out?
Answer:
2013
