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.

This study investigated the ability of fifteen disinfectants to eliminate pig-associated Salmonella, specifically focusing on monophasic Salmonella Typhimurium (S. 4,5,12:i:-). The study included three m-cresol, one glutaraldehyde/ formaldehyde, four glutaraldehyde/quaternary ammonium compounds (QAC), two iodine, two peracetic acid and three potassium peroxomonosulphate-based commercial disinfe...

Consumption of food contaminated with Escherichia coli O157:H7 and Salmonella can cause enteric disease in consumers. If not properly sanitized, knives used during animal harvest can spread these and other pathogens. This study evaluated the reduction of E. coli O157:H7 and Salmonella on harvesting knives after nonthermal sanitation. Knives were inoculated in cocktails of E. coli O157:H7 or Sa...

Query auto-completion (QAC) serves as a critical functionality in contemporary textual search systems by generating real-time query completion suggestions based on user’s input prefix. Despite the prevalent use of language models (LMs) QAC candidate generation, LM-based approaches frequently suffer from overcorrection issues during pair-wise loss training and efficiency deficiencies. To address...
