most polar drug and can be assigned the lowest log P value i.e. 0.16. Propanolol is the least polar drug because it contains non-polar aromatic functional group. Benzene is rendered non-polar due to its high structural symmetry of pi system of p-orbitals that distributes the charge equally along the ring. Therefore‚ propranolol can be assigned the highest log P value i.e. 3.21. Metoprolol is more polar than propranolol due to oxygen atom in the ether functional group. It can act as H-bond acceptor

creating a new geological period cannot be ignored. Sunspots are magnetic storms on the surface of the sun and an increase in the number of sunspots results in more radiation being emitted onto earth leading to short term climate change. Similarly the orbital variation of the earth over tens to hundreds of thousands of years can also lead to up to 10 degrees Celsius of climate change resulting in the transition from glacial to interglacial periods. Increased radiation during interglacial periods on earth

again extremely beneficial for the engineers to study. Kepler’s third law is well known as the law of harmonics‚ which defines some mathematical relationships in the motion of the planets. This law helps in establishing a comparison between the orbital period and the radius of the orbit of several different planets. Engineers have found this law extremely helpful

Period 3 Elements – Summary of Physical Properties Advanced Chemistry Book + website The elements in Period 3 of the periodic table are the elements sodium to argon. They represent the most straightforward trend in properties. As the atomic number of the elements increases across a period‚ the trend is from metallic to a non-metallic character. Electronegativity is a measure of an element’s ability to attract a shared electron pair to itself. Metals have a smaller electronegativity than 1

Physics 123 Ferro-Para-Di-Magnetism Magnetism is defined in the dictionary as the class of phenomena exhibited by a magnetic field. In physics there are a few types of magnetism. In this paper only three types will be covered which are ferromagnetism‚ paramagnetism‚ and diamagnetism. Ferromagnetism is considered the strongest type of magnetism‚ as it is a permanent magnet. A permanent magnet is one that remains a magnet after being magnetized by an outside magnetic field. Ferromagnetism is

needs its own propulsion system to get itself to the right orbital location and to make occasional corrections to that position. A satellite in geostationary orbit can deviate up to a degree every year from north to south or east to west of its location because of the gravitational pull of the Moon and Sun. A satellite has thrusters that are fired occasionally to make adjustments in its position. The maintenance of a satellite’s orbital position is called “station keeping‚” and the corrections made

Mercury Mercury is the smallest and closest to the Sun of the eight planets in the Solar System‚[a] with an orbital period of about 88 Earth days. Seen from the Earth‚ it appears to move around its orbit in about 116 days‚ which is much faster than any other planet. This rapid motion may have led to it being named after the Roman deity Mercury‚ the fast-flying

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. - Anatomy is the study of the structures and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. The kidneys remove wastes and water from the blood. 2. List‚ in order from least to most complex‚ the levels of structural
