PURPOSE We report three cases of Stenotrophomonas maltophilia endophthalmitis after uneventful extracapsular cataract extraction with intraocular lens implantation-related to surgical equipment contamination. CASE REPORT All patients developed acute, culture-positive endophthalmitis in a period ranging from 2 to 13 days. Cultures from vitreous tap, as well as those obtained from the hand-piec...

Sugar cane production in Brazil is one of the most competitive segments of the national economy, producing sugar and ethanol for internal and external markets. Sugar production is done basically in several steps: juice extraction, juice clarification and evaporation, syrup treatment and sugar boiling, crystallization, centrifugation and drying. Much heat exchange equipment is used in this proce...

This paper discusses a framework for implementation of a machine vision-based system for on-line identification of trash objects commonly found in cotton. Soft computing techniques such as neural networks and fuzzy inference systems can classify trash objects into individual categories such as bark, stick, leaf, and pepper trash types with great accuracies. This identification of trash objects ...

Selective Extraction and Recovery using Volatile Organic compounds is an emerging technology developed during the 1970s. This process can achieve the extraction of heavy metal contaminants from a matrix using a volatile organic reagent which passes through the feed material and reacts selectively with the desired metal salt, producing a volatile metal complex, removed from the matrix by a carri...

We present a rapidly fabricated micro-capillary electrophoresis chip that utilizes surface-tension-driven flow for sample injection and extraction of DNA. Surface-tension-driven flow (i.e. passive pumping) [G. M. Walker et al., Lab. Chip. 2002, 2, 131-134] injects a fixed volume of sample that can be predicted mathematically. Passive pumping eliminates the need for tubing, valves, syringe pumps...

Rolling bearing is main part of rotary machine. It is frail section of rotary machine. Its running status affects entire mechanical equipment system performance directly. Vibration acceleration signals of the third finishing mill of Anshan Steel and Iron Group wire plant were collected in this paper. Fourier analysis, power spectrum analysis and wavelet transform were made on collected signals....

Abstract The use of computer vision-related technologies can more efficiently achieve target detection UAVs and accurately identify the status substation equipment. Therefore, this paper proposes research on UAV equipment recognition technology based vision. Taking key technical links such as image preprocessing vision technology, feature extraction, construction coordinate system breakthrough ...

In order to solve the problem of insufficient energy supply on-line monitoring device transmission line, a sensor acquisition scheme directly installed on line is proposed. current power supply, induction kind extraction method with better practical applicability. Since devices and electronic equipment are often in strong magnetic field high voltage environment, designing stable reliable guaran...

operational variables of a mineral processing circuit are subjected to different variations. steady-statesimulation of processes provides an estimate of their ideal stable performance whereas their dynamicsimulation predicts the effects of the variations on the processes or their subsequent processes. in thispaper, a dynamic simulator containing some of the major equipment of mineral processing...
