In a polypeptide the main chain N-Calpha and Calpha-C bonds relatively are free to rotate. These rotations are represented by the torsional angles phi and psi, respectively.G N Ramachandran used computer models of small polypeptides to systematically vary phi and psi with the objective of finding stable conformations. For each conformation, the structure was examined for close contacts between atoms. Atoms were treated as hard spheres with dimensions corresponding to their vander Waals radii. so, phi and psi angles which cause spheres to collide correspond to sterically disallowed conformations of the

Count your blessings 1. First thing in the morning, make a list of ten blessings in your life you are grateful for.2. write why you are grateful for each blessings.3. Go back and read your list, either in your mind or out loud. When you get to the end of each one, say the magic words ,thank you ,thank you , thank you and feel the gratitude for that blessings as much as you possibly can.4. Repeat the first three steps of this magical practice every morning for the next 27

Biofertilizers are low cost, renewable sources of plant nutrients which supplement chemical fertilizers. These are nothing but selected strains of beneficial soil microorganisms cultured in the laboratory and packed in a suitable carrier. They can be used either for seed treatment or soil application. Types of BiofertilizersThe following types of biofertilizers are available to the farmers in India.• Nitrogen fixing biofertilizerseg. Rhizobium, Bradyrhizobium, Azospirillum and Azotobacter.• Phosphorous solubilising biofertilizers (PSB)eg. Bacillus,Pseudomonas and Aspergillus• Phosphate mobilizing biofertilizereg. Mycorrhiza• Plant growth promoting biofertilizerseg. Pseudomonas sp How biofertilizers work?• Biofertilizers fix atmospheric nitrogen in

The nature of an object or material that has been charged is depends on material used in the object. If the object is made of conductive material then it is Conductor and if the object is made of non-conductive material then it is Insulator and If the object is made of mixed type of material then it is Semiconductor;Conductors are the objects or materials that allow electrons to flow freely from particle to particle. An object created by using conducting material will allows charge to be transferred across the entire surface

Gonorrhea is an infection that is caused by the bacterium Neisseria gonorrhoeae. The usual symptoms in men are a burning sensation with urination and discharge from the penis. Women have no symptoms about half the time or have vaginal discharge and pelvic pain. In both men and women, if gonorrhea is left untreated, it may spread locally, causing inflammation of the epididymis or pelvic inflammatory disease or throughout the body, affecting joints and heart valves.Testing all women who are sexually active and less than 25 years of age each year is

The placenta is an organ that associates the creating baby to the uterine divider to permit supplement take-up, thermo-control, squander disposal, and gas trade by means of the mother’s blood supply; to battle against inner disease; and to deliver hormones which bolster pregnancy. The placenta gives oxygen and supplements to developing hatchlings and expels squander items from the baby’s blood. The placenta connects to the mass of the uterus, and the hatchling’s umbilical rope creates from the placenta. These organs associate the mother and the baby. Placentas are a characterizing normal for

Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to their leaves. Plants are able to absorb essential elements through their leaves. The absorption takes place through their stomata and also through their epidermis. Transport is usually faster through the stomata, but total absorption may be as great through the epidermis. Plants are also able to absorb nutrients through their bark.Foliar feeding was earlier thought to damage tomatoes, but has become standard practice EffectivenessH.B. Tukey was head of Michigan State University (MSU) Department of Horticulture in the

Logic circuit for Digital system may be combinational or sequential. A combinational circuit consists of Logic Gates whose output at any time are determined from the present combination of input. A Boolean circuit perform an operation that can be specified logically by a set of Boolean function. Each input and out variable exists physically as a binary signal that represent logic “1” and Logic “0”. In many application the source and destination are store registers.It the register are include with the combinational Gates, then the total circuit considered as sequential circuit.
