Caenorhabditis elegans postembryonic development consists of four discrete larval stages separated by molts. Typically, the speed of progression through these larval stages is investigated by visual inspection of the molting process. Here, we describe an automated method to monitor the timing of these discrete phases of C. elegans maturation, from the first larval stage through adulthood, using...

Photocopies of the ballots challenged in the 2008 Minnesota elections, which constitute a public record, were scanned on a high-speed scanner and made available on a public radio website. The PDF files were downloaded, converted to TIF images, and posted on the PERFECT website. Based on a review of relevant image-processing aspects of paper-based election machinery and on additional statistics ...

Most present studies on the acoustic emission signals of rotating machinery are experiment-oriented, while few of them involve on-spot applications. In this study, a method of redundant second generation wavelet transform based on the principle of interpolated subdivision was developed. With this method, subdivision was not needed during the decomposition. The lengths of approximation signals a...

On-line process chemical analysers A process analysis system (EPAS), from Eppendorf, for the chemical processing industry combines high-speed analysis with performance and reliability. Simplicity of analyser design guarantees long-term reliability and ease of service. Diagnostic software monitors and verifies analytical process data and analyser performance. An extensive process applications li...

The speed at which secretory vesicles fuse with the plasma membrane is a key parameter for neuronal and endocrine functions. We determined the precise time courses for fusion of small clear and large dense-core vesicles in PC12 and chromaffin cells by simultaneously measuring both plasma membrane areas and release of vesicular contents. We found that instantaneous increases in cytosolic Ca2+ co...

Many systems are usually subjected to the combined effects of degradation and random shocks at same time. Their failures competitive result soft failure caused by hard shocks. For operating machinery, wear is main mechanism, machine also subject shock during process. This paper proposes a new generalized surface model in combination with dependent competing processes; this proposed different fr...

Induction motors are widely employed in a variety of sectors, from household gadgets to industrial machinery. This mandates the deployment an effective and safe speed control device. may also run either direction, which is beneficial applications. The Motor Speed Direction Controller Project designed regulate induction motor's direction. on straight AC lines, amount power they receive determine...

The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...
