On The Theory of Time dilation in Chemical Kinetics
The rates of chemical reactions are not absolute but their magnitude depends
upon the relative speeds of the moving observers. This has been proved by
unifying theories of chemical kinetics, which are transition state theory,
collision theory, RRKM and Marcus theory, with the special theory of
relativity. Boltzmann constant and energy spacing between permitted quantum
levels of molecules are quantum mechanically proved to be Lorentz variant. The
relativistic statistical thermodynamics has been developed to explain
quasiequilibrium existing between reactants and activated complex. The newly
formulated Lorentz transformation of the rate constant from Arrhenius Equation,
of the collision frequency and of the Eyring and Marcus equations renders the
rate law also Lorentz variant. For a moving observer moving at fractions of the
speed of light along the reaction coordinate the transition state possess less
kinetic energy to sweep translation over it. This results in the slower
transformation of reactants into products and in a stretched time frame for the
chemical reaction. Lorentz transformation of the half-life equation explains
time dilation of the half life period of chemical reactions and proves special
theory of relativity and presents theory of relativistic chemical kinetics in
accord with each other. To demonstrate the effectiveness of the present theory,
the enzymatic reaction of methylamine dehydrogenase and radioactive
disintegration of Astatine are considered as numerical examples.Comment: 34 pages, 1 figures, 2 table
Quantum Mechanics of Insitu Synthesis of Inorganic Nanoparticles with in Anionic Microgels
In this work, we discuss the quantum mechanics of many-body systems i.e.
hybrid microgel consisting of negatively charged anionic microgels possessing
thick sheath of water molecules solvating its protruding anionic moieties and
nanoparticle captivated with in it. Thermodynamic feasibility of synthesis of
particular nanoparticle with in the microgel is dependent upon the magnitude of
interaction between nanoparticle, water molecules and microgel relative to sum
of magnitude of self-interaction between counterions and interaction between
counterions and microgel. Nanoparticles synthesized with in the microgels have
thick electronic cloud that oscillates under the influence of net interaction
potential of charged anionic moieties and solvent water molecules. Hamiltonian
describing energy of oscillating electronic cloud wrapped around nanoparticle
is mathematically derived to be equal to product of integral of electron
density and its position vector overall space multiplied with net electric
force acting on the oscillating electronic cloud of nanoparticle.Comment: 11 pages, 2 figures,mathematical modelling of use of microgel as

Effect of strength of gravitational field on electrode processes
Gravitational transformation of free energy dictates cell potential to be
lower near the vicinity of massive planet which results in the slower oxidation
and reduction of ions at their respective electrodes, in lower gravitational
field. The newly formulated gravitational transformations formulates decrease
in the electrode potential, cell potential and electrochemical rate constants
at lower gravitational field, this is due to greater flux of gravitons escaping
in to higher dimensions at lower gravitational fields than at higher
gravitational fields
Investigating viscous damping using a webcam
We describe an experiment involving a mass oscillating in a viscous fluid and
analyze viscous damping of harmonic motion. The mechanical oscillator is
tracked using a simple webcam and an image processing algorithm records the
position of the geometrical center as a function of time. Interesting
information can be extracted from the displacement-time graphs, in particular
for the underdamped case. For example, we use these oscillations to determine
the viscosity of the fluid. Our mean value of 1.08 \pm 0.07 mPa s for distilled
water is in good agreement with the accepted value at 20\circC. This experiment
has been successfully employed in the freshman lab setting.Comment: 13 pages, 5 figure
Price-setting for Residential Water: Estimation of Water Demand in Lahore
The Water and Sewerage Agency (WASA) of Lahore is facing soaring demand and rising costs. But while massive investments are made to augment supply, tariffs remain low and are not adjusted in line with growing expenses. This has resulted not only in heavy and increasingly unsustainable reliance on loans and subsidies, but also in consumers undervaluing the resource, resulting in its inefficient utilisation. In this scenario, water tariffs badly need to be reformed. This study explores the potential of a pricing policy to regulate residential water demand in order to achieve the objectives of cost recovery, efficient water use, and equitable allocation of water resources. To this end, a demand function is estimated using household level data about water consumption and socio-economic characteristics of 156 households supplied by WASA, Lahore, for the period 2004-2006. Under block-rate tariffs the price variable is endogenously determined and a system of simultaneous equations emerges, solved here using two-stage least squares method. The estimated model explains 57 percent variation in water demand. The study finds water demand to be inelastic to price and, considering WASA’s exceedingly low tariffs, recommends up to 50 percent increase in the current tariff structure. Further computations show that a 50 percent increase will not endanger lifeline water supply. However, tariff increases may not be felt uniformly across all income groups, and absence of income data remains a limitation of this study. The study also recommends linking the non-volumetric part of tariffs to wealth-determined variables, such as property value and income.Water Demand; Price-setting
Estimation of willingness to pay for improvement in dirnking water quality: a study of wasa, lahore
This study examines the existing water quality of Lahore and measures domestic household's willingness to pay for improvement in water quality services. To this end, a Tobit model is estimated by conducting a contingent valuation survey about household perceptions in six towns of Lahore. The results show that the factors affecting household's willingness to pay are coping costs that a household pay for ensuring quality of water.The study also finds the education level of head of family is an important factor in determining the willingness to pay for improved water services. It is recommended that by ensuring the supply and quality to the household additional revenue of 4.22 million rupees could be earned by the authority.Willingness to Pay, Tobit, Drinking Water Quality
