What is steam reforming process? Steam reforming or steam methane reforming is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is hydrogen production. The reaction is strongly endothermic (consumes heat, ΔHr = 206 kJ/mol). What is […]
What causes thermal noise?
What causes thermal noise? Thermal noise is generated as a result of thermal agitation of the charge carriers which are typically electrons within an electrical conductor. This vibration is dependent upon the temperature – the higher the temperature, the higher the agitation and hence the thermal noise level. How is thermal noise calculated? The magnitude […]
What is a healthy relationship with family?
What is a healthy relationship with family? In healthy family relationships, people trust and rely on each other for support, love, affection and warmth. Families often share common goals and work together to reach those goals (for example, children and young people may help their families get the dinner dishes done so that everyone can […]
What is the critical angle of ice?
What is the critical angle of ice? 49.8 degrees How do you find the critical angle in Snell’s law? The critical angle can be calculated from Snell’s law by setting the refraction angle equal to 90°. For any angle of incidence less than the critical angle, part of the incident light will be transmitted and […]

Can autopsy be performed without consent?
Can autopsy be performed without consent? Yes, an autopsy can be ordered by authorities without relatives’ consent in several situations. If an autopsy is not required by law or ordered by authorities, the deceased person’s next of kin must give permission for an autopsy to be performed. Can an autopsy be requested? Can anyone request […]
What is the main function of the jejunum and ileum?
What is the main function of the jejunum and ileum? The primary function of the jejunum is to absorb sugars, amino acids, and fatty acids. Both the jejunum and ileum are peritoneal. The ileum absorbs any remaining nutrients that did not get absorbed by the duodenum or jejunum, in particular vitamin B12, as well as […]
How did alchemists contribute to science?
How did alchemists contribute to science? Through the span of several millennia, alchemists “were learning fundamental principles of chemistry: breaking down ores, dissolving metals with acids, and precipitating metals out of solution [8].” This laid the foundations of basic scientific experimentation with modern alchemists such as Boyle emphasizing the … What were some contributions of […]

Pro: Less Herbicide Runoff. Con: More Herbicides. Pro: Higher Crop Yields. Con: You Need Patience. What are the disadvantages of no-till farming? Disadvantages With no-till […]
How fatigue crack is detected using edge current inspection?
How fatigue crack is detected using edge current inspection? Fatigue cracks tend to occur at bolt-jointed structures on an aircraft. In order to detect the damage quantitatively, a kind of change-prone micro eddy current sensor is designed and fabricated with flexible printed circuit board (FPCB) technology. Which wave is used in metal cracks detection? Ultrasonic […]
