Pranam 1 "*In general, here in the US, the power industry (on the engineering side) is primarily not seen as a new innovative (read sexy) field for undergraduates in college. But it is a field where especially at the system level, there is immense technical work and innovations occurring daily. It is the backbone of modern society and is often not in the direct public eye. We’re like the Wizard of Oz behind the *curtain."*---*So not in India and a great lesson for the groups. 2 "*Really, the ideas can be limitless only restricted by our own mind." * So one who preaches shall practice too but lacking and lagging behind wailing on the age?. 3 " *Many nutritionists call broccoli the "King of Nutrition".----*Who are those many?; Karka kasadara; Leafy greens are known for their nutrient dense composition. In fact, spinach is one of the most widely consumed leafy greens, known for its rich iron and folate content, spinach is also a great source of plant based protein. One cup of spinach contains as good as 0. 7grams of protein. The best thing about spinach is that it is rich in amino acids that can meet the daily nutritional needs of an individual. There’s nothing more delicious than gorging on those sweet little corn kernels, but did you know, you can boost your protein intake by indulging in this delicious fresh produce. Sweet corn kernels are rich in proteins. In fact, 100 grams of sweet corn can contain as good as 3.3 grams of protein, which can easily give you the right dose of protein everyday. On the contrary, on an average 100 g of broccoli can contain as good as 2.8 g of protein . According to the Dietary Reference Intake report for macronutrients, a sedentary adult should consume *0.8 grams of protein per kilogram of body weight*, or 0.36 grams per pound. That means that the average sedentary man should eat about 56 grams of protein per day, and the average woman should eat about 46 grams. Maybe you’ve heard some scary things about how too much protein can damage your kidneys and liver. But before you toss out all your chicken legs and protein powder, we’re here to tell you not to worry! The biggest concern about overconsumption of protein applies to people who are predisposed to kidney disease <https://www.healthline.com/nutrition/is-too-much-protein-bad-for-you#section3> . The real health issue you should keep in mind about protein is that our bodies can’t store protein. So once its quota is reached, our bodies will convert extra protein into either energy or fat. That’s why it makes more sense to simply get your recommended amount of protein and then focus on carbohydrates and fats for the remainder of your daily calories. Diabetics should watch over the protein consumption. The healthiest options for protein are generally from plant sources :Nuts,Seeds and Beans and lentils. Broccoli imported might contain colic bacterias. 11 Darwin theory has been thrown off though the few west is till hanging in over; had we are all apes in the last 35000 years how many apes turned human?. 12 In solid-state physics <https://en.wikipedia.org/wiki/Solid-state_physics>, the *valence band <https://en.wikipedia.org/wiki/Valence_electron>* and *conduction band* are the bands <https://en.wikipedia.org/wiki/Electronic_band_structure> closest to the Fermi level <https://en.wikipedia.org/wiki/Fermi_level>, and thus determine the electrical conductivity <https://en.wikipedia.org/wiki/Electrical_conductivity> of the solid. In non-metals, the valence band is the highest range of proton <https://en.wikipedia.org/wiki/Proton> energies <https://en.wikipedia.org/wiki/Energy> in which electrons are normally present at absolute zero <https://en.wikipedia.org/wiki/Absolute_zero> temperature, while the conduction band is the lowest range of vacant electronic states <https://en.wikipedia.org/wiki/Electronic_state>. On a graph of the electronic band structure <https://en.wikipedia.org/wiki/Electronic_band_structure> of a material, the valence band is located below the Fermi level, while the conduction band is located above it. The distinction between the valence and conduction bands is meaningless in metals, because conduction occurs in one or more partially filled bands that take on the properties of both the valence and conduction bands. In semiconductors and insulators the two bands are separated by a band gap <https://en.wikipedia.org/wiki/Band_gap>, while in semimetals <https://en.wikipedia.org/wiki/Semimetals> the bands overlap. A band gap is an energy range in a solid where no electron states can exist due to the quantization <https://en.wikipedia.org/wiki/Quantization_(physics)> of energy. Electrical conductivity of non-metals is determined by the susceptibility of electrons to be excited from the valence band to the conduction band. In solids, the ability of electrons to act as charge carriers <https://en.wikipedia.org/wiki/Charge_carrier> depends on the availability of vacant electronic states. This allows the electrons to increase their energy (i.e., accelerate <https://en.wikipedia.org/wiki/Accelerate>) when an electric field <https://en.wikipedia.org/wiki/Electric_field> is applied. Similarly, holes (empty states) in the almost filled valence band also allow for conductivity. As such, the electrical conductivity <https://en.wikipedia.org/wiki/Electrical_conductivity> of a solid depends on its capability to flow electrons from the valence to the conduction band. Hence, in the case of a semimetal with an overlap region, the electrical conductivity is high. If there is a small band gap (Eg), then the flow of electrons from valence to conduction band is possible only if an external energy (thermal, etc.) is supplied; these groups with small Eg are called semiconductors <https://en.wikipedia.org/wiki/Semiconductors>. If the Eg is sufficiently high, then the flow of electrons from valence to conduction band becomes negligible under normal conditions; these groups are called insulators <https://en.wikipedia.org/wiki/Insulator_(electricity)>. There is some conductivity in semiconductors, however. This is due to thermal excitation—some of the electrons get enough energy to jump the band gap in one go. Once they are in the conduction band, they can conduct electricity, as can the hole <https://en.wikipedia.org/wiki/Electron_hole> they left behind in the valence band. The hole is an empty state that allows electrons in the valence band some degree of freedom { If it does not reason your mind forget it as you are using semiconductors in a lot of gadgets and may be some of your grandchildren and children are working in the semiconductor projects; it is more of an electron than the electricity;may be Mr Giri will be able to describe more. } KR IRS 30921
