Chlorine-based bleaches are known to make bloodstains invisible, but applying chemicals such as luminol or phenolphthalein will still reveal the presence of haemoglobin – crucial for identifying blood – even after up to 10 washes.
What is the difference between simple and complex receptive fields? The difference between the receptive fields and the characteristics of simple and complex cells is the hierarchical convergent nature of visual processing. Complex cells receive inputs from a number of simple cells.
What is the difference between simple and complex cells? For example, a complex cell will respond to a dark bar on a light background and a light bar on a dark background. In contrast, a simple cell only responds to one but not the other. Moreover, complex cells do not have peak location sensitivity as simple cells do.
What types of receptive fields do simple cells have? The receptive fields of simple cells, a type of orientation-selective cell, consist of adjacent, oriented regions alternately receiving ON-center and OFF-center excitatory input.

Can a ct scan detect metal?
Foreign bodies, 0.5 mm in size, made of metal, stone, glass, and graphite were detected well on all scans; 0.5-mm-in-size graphite was detected only by CT scan. Metal, stone, glass, tooth, and graphite measuring 1 and 2 mm were detected on all scans. Wood was not detected in any of the scans.

Can a pulse oximeter detect lung cancer?
As shown here, the LCSS and pulse oximetry may be regarded as valuable tools for prognostic assessment in advanced lung cancer. SpO2 was independent of most LCSS data, and the combination of SpO2 and LCSS offered independent prognostic information on overall survival.
How to detect gallbladder symptoms?
This test is the one most commonly used to look for signs of gallstones. Abdominal ultrasound involves moving a device (transducer) back and forth across your stomach area. The transducer sends signals to a computer, which creates images that show the structures in your abdomen.
Can antibodies detect nucleic acids?
Abstract. Detection of nucleic acids using antibodies is uncommon. This is in part because nucleic acids are poor immunogens and it is difficult to elicit antibodies having high affinity to each type of nucleic acid while lacking cross-reactivity to others.
Can you use a Pinpointer instead of a metal detector?
While a regular metal detector may be useful for searching large areas in a relatively short amount of time, a pinpointer can save you time when it comes down to finding exactly where an object might be and if you might have already dug it up.
What wavelengths do we feel as heat?
For example, hot charcoal may not give off light but it does emit infrared radiation which we feel as heat. The warmer the object, the more infrared radiation it emits. Humans, at normal body temperature, radiate most strongly in the infrared at a wavelength of about 10 microns.
