Attention is drawn to the possibility of performing monocular indirect ophthalmoscopy with a pen torch and a condensing lens when facilities for binocular indirect ophthalmoscopy are not available.

Gene Regulatory Networks are models of gene regulation. Inferring such model from genome-wide geneexpression measurements is one of the key challenges in modern biology, and a large number of algorithms have been proposed for this task. As there is still much confusion in the current literature as to what precisely Gene Regulatory Networks are, it is important to provide a definition that is as...

Several years of extensive research using the new powerful techniques of molecular biology have enabled the direct comparison of functionally or evolutionarily related genes and their products at the nucleotide and amino acid sequence levels. Two types of synthase with similar functions are discussed as an interesting example. Stilbene synthases, e.g. resveratrol synthase, produce the stilbene ...

A literature review on the two-phase flow inside plain tubes, especially for refrigerant R1234yf, is conducted in this research. The boiling, condensation, and visualization of low GWP were examined experimentally to measure heat transfer coefficients pressure drop refrigerant, also present a pattern map. measurements carried out smooth circular tubes with internal diameters 8.2 mm mass velocit...
