INFLUENCE OF FERROCHROME SLAG ON MECHANICAL PROPERTIES OF DRY BUILDING FLOORING MORTAR

The possibility of using ferrochrome slag in the composition of dry building flooring mixes was studied. It is found that the introduction of 25% slag in conjunction with silica fume increases the strength of the mortar by 40 %.Изучена возможность использования феррохромового шлака в составе сухой строительной напольной смеси. Выяснили, что введение 25 % шлака совместно с микрокремнеземом повышает прочность раствора на 40 %

Algorithm of Hepatitis B Vaccinal Prevention at Children with Acute Lymphoblastic Leukemia in Dynamics of Program Therapy

Purpose: To create the algorithm of hepatitis B vaccinal prevention at children with acute lymphoblastic leukemia. Materials and Methods: The data of 181 children with acute lymphoblastic leukemia, from which 99 patients received specific hepatitis B prevention with vaccine «Engerix B», have been investigated. The authors have assessed correlations between efficiency of offered vaccinal prevention and leuco/neutropenia degrees at patients in days of vaccinations. The analysis of hepatitis B infect level at stages of vaccination was carried out. Results: The algorithm of hepatitis B vaccinal prevention at children with acute lymphoblastic leukemia is offered

2005 Johns Hopkins Summer Workshop Final Report on Parsing and Spoken Structural Event Detection

This project investigated the interaction between parsing and the detection of structural metadata in conversational speech, including sentence boundaries, edits (the reparandum portion of speech repairs), and fillers. In terms of parsing, we explored alternative methods of exploiting metadata information in parsing models and measured how varying accuracy in transcription and metadata information affects parsing accuracy. In the other direction, we similarly considered how syntactic and prosodic knowledge could be leveraged in metadata detection, measuring how this knowledge impacts metadata detection accuracy. As part of this work, we investigated metrics for evaluating parse accuracy in the presence of transcription and metadata detection errors, and we report on our experience using these metrics with several parsers and across varying experimental conditions. A range of methods for handling edits during parsing were evaluated in this research (excision, addition of markups to the input string, and grammar modification). We also developed a ToBI (a prosodic structure annotation scheme [SBP + 92]) prosodic event classifier and describe its evaluation. Finally, we present methods for effective n-best sentence boundary candidate generation and reranking using syntactic, prosodic, and other features. These studies are complemented by a second set of reranking investigations wherein we optimize sentence boundar
