Samples of effluent and soil were collected from a reed bed system used to remediate liquid waste from a wool finishing mill with a high use of quaternary ammonium compounds (QACs) and were compared with samples of agricultural soils. Resistance quotients of aerobic gram-negative and gram-positive bacteria to ditallowdimethylammomium chloride (DTDMAC) and cetyltrimethylammonium bromide (CTAB) w...

The recovered results showed that: the incidence of Salmonella typhymurium in observed commercial egg-layer flocks; isolation from 5 flocks (33.7 %) out 15 flocks, mortalities rates at end 78 weeks age was 16 % and also, current egg-production, average egg weight, hen housed day, percent peak egg-production were: 68 %,59.2 gm, 68.4%, 318, 78% 70%, respectively. efficacy most common disinfectant...

We present our unified approach to question answering in different languages and describe our experiments on the Japanese language NTCIR-3 Question Answering Challenge (QAC-1) tasks 1 and 2. The model we use for Japanese language question answering (QA) is identical to the one we have applied successfully on the English language TREC QA tasks, based on a novel statistical, non-linguistic and da...

We propose definitions of QAC, the quantum analog of the classical class AC of constant-depth circuits with AND and OR gates of arbitrary fan-in, and QACC[q], where n-ary MODq gates are also allowed. We show that it is possible to make a ‘cat’ state on n qubits in constant depth if and only if we can construct a parity or MOD2 gate in constant depth; therefore, any circuit class that can fan ou...

In this paper, we describe two Question Answering systems that participated in the NTCIR QAC task. The first system, SAIQA-Ii, follows a standard worddistance approach. This system was designed to output the top five candidates and participated in TASK-1. The second system, SAIQA-Is, employs a logic-based approach. This system was designed to output only the most likely candidates and participa...

statement of problem: surface disinfection is an important aspect of infection control in dentistry. a new generation of quaternary ammonium components (qacs) is gaining popularity as high-level disinfectants. two types of qac sprays, uniseptaquick and solarsept, are being widely used by iranian dentists. purpose: the aim of this study was to evaluate the clinical efficiency of unisepta quick a...

This note describes OKI QA system for QAC-2 of NTCIR4. Our system has three characteristics: dependency-matching based answer extraction, run-time tagging, and learning-based query type analyzer. The result of the experiment implies that dependency revision technique will occupy an important position.
