Metoclopramide HCl are used to reduce vomiting and nausea. The availability on the market in the form of tablet, syrup and injection. Patient tend to prefer take drugs by oral use because it was easier. Chewable tablet is the new product as the alternative ways to treatment children and adult patient who had difficulity problem of swallowing drugs. Objectives: This research aims to formulate the chewable metoclopramide HCl tablets using diluent variations to get a better physical quality test. Chewable tablets of metoclopramide HCl are made using diluent variations, they are mannitol, sucrose, lactose. Formula I mannitol, formula II sucrose, and formula III lactose. Chewable tablet preparations are made by the wet granulation method. Data collection was performed on physical characteristics including organoleptic, weight uniformity, uniformity of size, tablet hardness, tablet fragility, disintegration time, metoclopramide HCl levels. Physical quality test results were statistically analyzed to determine the effect of variations in the diluent on the characteristics of chewable tablets. The results of this research have an influence on the physical quality and uniformity of contents of various types of diluent variations between each formulation. In this research, fillers have an important role in the preparation of chewable metoclopramide tablets to determine the physical quality of the tablets and the uniformity of their contents. The variation of diluent that gives better results is mannitol. This is because formulas that use mannitol have uniformity in content that meets the requirements, faster disintegration time, and physical quality of tablets that still meet the requirements, when compared to the first and second formulations. The variation of diluent that gives better results is mannitol.

Reliability is one of the key dimensions of the quality of services and products that should be always evaluated. Growth and development of industries can be achieved by appropriate reliability engineering of products. Companies should evaluate and predict the reliability of products and accordingly find and fix the potential problems. In this regard, early detection of reliability problems based on the parameters of the production line or quality test results can prevent future warranty costs. Early detection of reliability problems based on production process and test data has not gained much attention in the literature. Therefore, an early detection model for predicting the reliability of products according to their quality test results is proposed in this research. For this purpose, hot test and warranty data of car engines manufactured by an automotive company are utilized. This data are prepared to predict engine reliability after preprocessing and removing inefficient data. Then, engines are divided into two homogeneous clusters using particle swarm optimization (PSO) clustering algorithm. Afterwards, the data in these clusters are used to feed the Artificial Neural Network (ANN) to predict the reliability of the engines. The obtained results show that the proposed ANN-based method is able to predict the reliability of the engines based on engine kilometers operated and hot test results. Also, it is shown that the proposed method outperforms the Cox proportional hazards model which has previously been used for early detection of product reliability.

Fifty herds with the highest annual average mastitis cell counts in England and Wales were compared with 50 herds with the lowest cell counts. The milk-quality test results of these herds for milk fat, protein and lactose contents, and total bacterial count (TBC), over the 6 winter months, October 1982 to March 1983, were examined.The herds with high cell counts had an arithmetic mean of 2.50 × 109 cells/1 and the herds with the low cell counts had 0.117 × 109 cells/1. The milk-quality test results were: milk fat, 39.8 and 40.0 g/kg; protein, 33.2 and31.5 g/kg; lactose, 42.8 and 46.9 g/kg; and TBC, 139 and 12.0 × 106/1 for the herds with the high and low cell counts, respectively. There were highly significant differences in protein and lactose contents and in TBC. When the average monthly results were compared, these differences were statistically significant in all months. On average, lactose was 9% lower and protein 5% higher in the herds with the high cell counts when compared with the herds with the low cell counts.

The principle of restraining the harmonic using the series reactors was introduced and the relationships between circuit condition and the harmonic current were analyzed in this paper.The considered problems in selecting the reactance rate were discussed. On the base of power quality test results at a certain region in China, a selection method of reactance rate of series reactors, rated voltage and capacity of a capacitor were put forward to realize the compensation for reactive power.

This paper examines empirically the value of early exercise by testing the ability of two American put valuation models to predict the early exercise premium for the S&P 100 American put options. An accuracy test and a quality test are performed on (1) the MacMillan and Barone-Adesi and Whaley model, and (2) the Carr, Jarrow and Myneni model. The test results show that early exercise premium is significant regardless of moneyness. Moreover, consistent with the theory, the value of early exercise is significantly negatively related to moneyness and interest rates and significantly positively related to time to maturity and to the volatility of the underlying index. Both American put valuation models examined do not fully capture the value of early exercise embedded in American put prices.
