Feeding Speed

The purpose of this paper is to improve line productivity using line balancing technique and a reduction of work variation using an automated part feeder. This is due to the fact that the conventional assembly line manually feeds a part on to the production line by a worker. The feeding cycle is not constant and varies from time to time. Thus, the production rate is not constant and varied by the worker feeding speed. In addition, the assembly line itself does not fully balance. The operation time of each station is not well designed; as a result, all of the stations but the bottle-neck one experience an idle time. The balance efficiency is only at 40.33 percent which means that 59.67 percent of the total production time is balanced delay. Once the automated feeding machine which a buffer is designed and implemented. The cycle time can be set at 6 sec. and with the line balance technique the operator can be reduced from 11 to 9 persons. As a result, the productivity is substantially increasing around 138 percent and the new balance efficiency is 85.12 percent.

Although the reason is not clear, mileage is commonly recommended as an indicator to evaluate the oil drain interval of a car. This paper tries to investigate whether the mileage is the most suitable indicator to evaluate the oil drain interval based on scientific experiments and data analysis method. Three civilian cars and motor oils (contained mineral oil, semisynthetic oil, and synthetic oil) were subjected to road tests under urban traffic condition. The real-time driving parameters comprising speed, mileage, idle time, engine operation time, and number of starts were obtained by on-board diagnostic system. Synchronous oil samples were collected about every 30 days. The physicochemical properties and component changes of experimental oils were analyzed in laboratory. The effects of driving parameters on oil properties were studied with the improved grey relational analysis method. The results show that the influencing factors of driving parameters on motor oil degradation were different in different experimental cars. The influence of mileage on oil degradation was not obvious. The idle time of engine, engine operation time, and number of starts were the three most significantly influential factors on oil deterioration after comprehensive analysis of the three experimental cars.

Periampullary Neoplasms

Introduction: Pancreaticoduodenectomy is the procedure of choice for periampullary neoplasms. It is considered as a major surgical procedure. It is associated with relatively higher postoperative mortality and morbidity rate, however, with development of technology, proper patient selection, meticulous operative technique, appropriate postoperative care, morbidity and mortality rate has decreased subsequently. Up to the 1970s, the operative mortality rate after pancreaticoduodenectomy approached 20% but it has been reduced to less than 5% in recent reports. This study is designed to evaluate the postoperative outcomes of pylorus-preserving pancreaticoduodenectomy procedure in our set up. Objective: To evaluate the outcome of the pylorus-preserving pancreaticoduodenectomy procedure with the intention to measure operation time and per-operative bleeding, observing postoperative anastomotic leakage and gastric emptying time. To find out postoperative wound infection and complications to detect the dumping syndrome. Materials and Methods: A prospective observational study was carried out in the Department of Hepatobiliary Surgery, Combined Military Hospital, Dhaka from July 2013 to January 2017. Fifty patients who underwent pylorus-preserving pancreaticodudenectomy procedure were included in this study. Results: Out of 50 postoperative patients, 12(24%) patients developed complications. Of these patients, 3(6%) developed wound infection, 2(4%) developed bile leakage and 2(4%) developed postoperative haemorrhage. Pancreatic fistula, vomiting, delayed gastric emptying and abdominal collection all were 1(2%) each. Postoperative mortality was 3(6%). Conclusion: The present study demonstrated the development of postoperative complications after pylorus-preserving pancreaticoduodenectomy is as similar as published in different studies. Better outcome can be achieved with meticulous pre-operative evaluation of risk factors and per-operative skill maneuvering. Journal of Armed Forces Medical College Bangladesh Vol.13(1) 2017: 42-45
