The lean manufacturing concept is a systematic minimization of waste and non-value activities in production processes introduced by the Toyota production system. In this research, lean manufacturing is implemented in a cement production line. Value Stream Mapping (VSM) is applied to give a clear picture of the value chain in cement production processes and to highlight the non-value-added in the shop floor. To begin, the existing VSM is constructed based on the information and data gathered during visiting and observing the manufacturing process in the firm. As a result, the excess inventory between workstations was identified as a major waste generation, hence, the proposed VSM conducts further improvement and makes action plans to alleviate the unwanted activities. Then, the takt time to ensure smooth material flow and to avoid any occurring delay or bottleneck in the production line was figured out. The supermarket pull-based production control is suggested to be adopted in the future map. Two pull production strategies are selected in this case. The first is applying the Kanban system to control the level of inventory between workstations. The other is the CONWIP approach to control the amount of work in process to the entire production line. The outcome of the proposed models indicates a decrease of the none-value time from 23 days in the current state to about 4 and 2 days in Kanban and CONWIP systems respectively, so the CONWIP was suggested as most efficient. Some suggestions for further research are also mentioned.

Productivity is an important parameter for all small and medium scale manufacturing industries. Lean manufacturing emerged as production strategy capable of increasing productivity by identifying and eliminating non value added activities. This article deals with productivity improvement in a pre-assembly line of gearbox manufacturing company with a case study using lean concepts like process flow chart, process Gantt chart and time study. This paper illustrates using a case study on how a value stream mapping has to be carried out in a planet carrier pre-assembly line. Value stream mapping and work standardization are the key tools used in lean manufacturing and lean transformation. It makes the process smoother, helps in reduction of lead time and ultimately increasing the productivity. From the observed results it was found that, the productivity has been increased from 7 pieces to 10 pieces in the first step assembly when the proposed VSM was implemented. The second step processing time was reduced by the execution of proposed value stream mapping with TAKT time of 126 minutes and 165 minutes of processing time for demand of 10 pieces were achieved and the overall processing time has been reduced by about 24%.

ABSTRACT Six rumen-fistulated, overnight-fasted, female British Saanen goats were used. In preliminary experiments on two of the goats, evidence was obtained that inflation of a balloon with water in the cranial sac of the rumen was accompanied by inhibition of GH release. In a definitive series of experiments on the other four goats (one goat on 1 day = one experiment), a total of 96 experiments were carried out, 48 of which were balloon inflations with 2·5 litres water at 37 °C in the cranial sac of the rumen for 40 min and 48 were control experiments on alternate days. It was found that the mean plasma GH concentration of the samples taken at the end of the 40-min inflation period was significantly (P < 0·05) lower than the mean value of the samples taken at the start of inflation. Mean control values at the start and finish of inflation were not significantly different. There were no significant differences between mean plasma insulin concentrations at the start and finish of inflation in experimental and control groups. It is concluded that distension of the cranial rumen in the goat is a signal which can inhibit the release of GH. J. Endocr. (1985) 104, 159–163

This study aims to investigate English as a Foreign Language (EFL) teachers’ misbehaviours in class and their students’ reactions to these misbehaviours. Towards this end, 60 classroom observations of six English language teachers (N=10 each) were conducted at a public school in Jordan. Moreover, a survey was used to elicit 201 students’ reactions to their teachers’ misbehaviours by gauging their satisfaction with the teachers’ communication styles. Finally, the teacher participants were interviewed in order to more deeply understand why such misbehaviours occurred. Analysis of the data is grounded in the Expectancy Violation Theory. The results revealed that when the mean value of teachers’ communication style was more than 3 on a 5-point Likert Scale, the students often perceived their teachers as being positive, and the students compensated most of their teachers’ misbehaviours. However, when the mean value was below 3, the teachers were perceived as being negative, and the students reciprocated for most of the misbehaviours. The results also showed that the students are more tolerant towards their teachers’ misbehaviours as long as the teacher is perceived to be positive. The study provides insights into understanding the student-teacher relationship in EFL classes.

Serum Periostin

Background: There are few biomarkers that can be easily accessed in clinical settings and may reflect refractory Th2-eosinophlic inflammation and remodeling of the asthmatic airways. Serum periostin may be one such biomarker to aid our understanding of the patho-bio-physiology of asthma and exercise induced asthma. The aim of the study is to explore the relationship between serum periostin level and exercise induced bronchoconstriction in asthmatic children. Materials and Methods: This cross-sectional study was carried out on (90) children both sexes aged from 6 to 15 years including, (60) children with bronchial asthma and (30) children were enrolled as control group in the period from January 2018 to January 2019. Patients were randomly classified into two groups: I) Patient group: divided into 2 groups according to standardized treadmill exercise challenge test: Group A: (30) asthmatic children with positive test. Group B: (30) asthmatic children with negative test. II-Control group: (30) children apparently healthy with no personal or family history of asthma. All children were subjected to the following Investigations: Chest x-ray, pulmonary functions tests (FEV1 & PEFR) except controls, Laboratory investigations as CBC and Serum periostin level. Results: The mean values of both the percentage of PEFR and FEV1 after exercise in group A were significantly lower than those in group B and the percentage of PEFR and FEV1 after exercise in each group were significantly lower than the percentage before exercise in the same group. The mean value of eosinophilic count in group A was significantly higher than (group B and control group) and the mean value of eosinophilic count in group B was significantly higher than control group. The mean value of serum level of periostin in group A was significantly higher than (group B and control group), however, there was no significant difference between group B and control group as regard to serum level of periostin. Chest tightness, cough and wheezes after exercise and eosinophilic count in patients with high serum periostin level were significantly higher than patients with low serum periostin level, and both PEFR and FEV1 after exercise in patients with high serum periostin level were significantly lower than patients with low serum periostin level. Also the normal serum periostin levels vary among different age groups. Conclusion: Serum periostin level can be considered as a useful biomarker for diagnosis of Exercise induced bronchospasm (EIB) in asthmatic children especially when lung function test cannot be done However, cautious is required in evaluating serum periostin levels in children because it varies with age.
