Science of peace














P D Tyagi

Every person on earth is in search of peace. Absence of peace leads to tensions, which put stress on human brain. Since stress is directly proportional to strain; therefore, mental stress puts strain on delicate organs like heart, kidney etc. and results in the deformity of such organs and/or their permanent failure, which may even result into death. Therefore, main concern is how to avoid tensions and develop peace. Following is the equation of peace:

 

R+ + pct + F                K (R+ + pct + F)

P ∞ ──────────   =        ────────── (1)

R + A                         R + A

where P = Peace, R+ = +ve results, R = ve results, p = patience, c = contentment, t = tolerance, F = faith in God, A = arrogance (proud) and K=constant. Here, R+ and R are physical parameters that are governed by human intelligence and hardwork. F, A and pct are temperamental parameters that are governed by human nature.

Effects of quality circle participation on employee perception and attitude in five Malaysian companies





T R Abo-Alhol, M Y Ismail, S M Sapuan &
M M Hamdan

This study investigates changes in employee attitude brought about through participation in Quality Circle (QC). Assessment of circle performance was measured by technical aspects, length of participation, training, member feelings about QCs, job satisfaction and job commitment. Study illustrates the impacts of participation on 130 workers from 5 Malaysian companies participated in a survey. Results show that QCs develop positive attitudes among employees who derive job satisfaction when they feel that their companies are a good place to work and consequently, more willing to extend their efforts for their companies.

Taguchi approach with multiple performance characteristics for burr size minimization in drilling








V N Gaitonde, S R Karnik, B T Achyutha &
B Siddeswarappa

This paper presents application of Taguchi optimization method for simultaneous minimization of burr height and burr thickness influenced by cutting conditions and drill geometry. The approach of Taguchi design for multi-objective optimization problem is based on the introduction of a new concept of fitness function for each trial of orthogonal array. The fitness function is derived through mapping the objective functions of the drill optimization problem. In present work, optimal values of cutting speed, feed, point angle and lip clearance angle are determined for a selected drill diam to minimize burr height and burr thickness during drilling of AISI 316L stainless steel workpieces. The effectiveness of proposed method is demonstrated through simulation results and experimental verifications.

Design and development of microcontroller based human airway pressure measurement system with real time graphical display for anaesthesia ventilator







R N Sengupta, Jaspreet Kaur &

Jagdish Kumar

A microcontroller based hardware design and system software associated with the graphical visualization of the airway pressure data acquisition system has been designed and developed, and successfully incorporated in indigenous prototype of anaesthesia ventilator. An inexpensive airway pressure monitoring system based around 80C31 microcontroller with RAM, EPROM, AD574 ADC, peripheral interface devices and graphical LCD etc., is a module of the indigenously developed instrument. What has been envisaged here is to get a real time pressure waveform on LCD. Air pressure changes over a respiratory cycle. This makes anaesthetist to have a feeling of how air pressure in the tract changes with time. An accurate and sensitive piezoresistive type of air pressure sensor has been used outside the mouth and inside the piping.

Estimation of Rabeprazole Sodium in tablet dosage form by rapid isocratic reversed phase high performance liquid chromatography using volatile buffer additives




















V L Kulkarni & P P Mahulikar

A simple, rapid and reproducible reverse phase high performance liquid chromatographic (RP-HPLC) assay method for determination of Rabeprazole Sodium (RS) in solid dosage form (20 mg) has been developed. Recovery of RS in tablets was 95.5-96.8%. Chromatographic response of the analyte (100-500 mg/ml) was linear with correlation coefficient more than 0.99. Runtime of the method is very short and mobile phase additives used are volatile that are also suitable for mass spectrometry analysis. Therefore, this method could be used for routine quality control analysis and in bio-analytical work.

A comparative study of non-conventional coagulants vis--vis traditional coagulant on chhana (an acid and heat coagulated product from milk)









Mahuya Bandyopadhyay, Runu Chakraborty & Utpal Raychaudhuri

Three non-conventional, low cost, food grade organic acids (acetic acid, fumaric acid, tartaric acid) were effectively used as coagulant at three different concentrations (0.5, 1 and 2%) in the manufacture of chhana (a heat and acid coagulated milk protein mass and an Indian equivalent to cottage cheese) as substitute for sour whey. Chhana prepared by all type of coagulants including sour whey were found similar in quality. Concentrations (0.5 and 1%) of three acids produced higher yield than sour whey. Fumaric acid (all conc.), tartaric acid (1 & 2%) and acetic acid (2%) gave higher total solid recovery than sour whey. Chhana made by three acids (1 & 2%) contained higher fat and protein than chhana made by sour whey. The three organic acid coagulants produced little bit hardy, chewy, gummy, elastic and cohesive chhana than sour whey but that chhana could be better utilized for making dry chhana sweets. All three organic acid coagulants (1%) were effectively used in the manufacture of chhana as substitute for sour whey.

CNG exhausts emission modeling: Neural network approach








Kirti Bhandari, Ch Ravi Sekhar, A M Rao & S Gangopadhyay

Traditional statistical regression and Artificial Neural Network (ANN) modeling techniques were applied to assess the emission characteristics of CNG vehicles (cars and three wheelers) to understand the influence of explanatory parameters like vehicle age, vehicle type and air-fuel ratio on emissions of CO, HC, CO2 and O2. For ANN modeling, multilayer feed-forward neural network with single hidden layer was considered and back propagation algorithm was applied for training ANN model. ANN models are shown better predictive models than the traditional statistical modeling techniques for predicting the CNG exhaust emissions (CO, HC, CO2, and O2).

Cadmium (II) ion and nickel (II) ion biosorption on yeast: Application of equilibrium model









Padma Vasudevan, V Padmavathy &
S C Dhingra

Experimental data on cadmium (II) and nickel (II) ion sorption on deactivated protonated yeast over a wide range of sorbent and initial metal concentrations, were analyzed by using an equilibrium model based on a thermodynamics approach. Model describes relationships between the equilibrium concentration of metal, metal sorption per unit biomass dosage and concentration of sorbent and initial metal concentrations at constant pH and temperature. Model fits the data well for the sorption of nickel (II) ion onto deactivated protonated yeast at pH 6.75. However, model could be applied only for a given substrate concentration for sorption of cadmium (II) ion onto sodium form of deactivated protonated yeast at pH 6.5.
