Sensor & instrumentation system : series 1

This book is an introduction to many of the topics that an engineer needs to master in order to successfully design experiments and system measurement. In addition to descriptions of common measurement systems, the book describes computerized data acquisition systems, common statistical techniques, and guidelines for planning and documenting experiments. More comprehensive studies of available literature and consultation with product vendors are appropriate when engaging in a significant real-world experimental program. It is to be expected that the skills of the experimenter will be enhanced by more advanced courses in experimental and instrumentations systems design and practical experience

Restoration of Soil Health for Achieving Sustainable Growth in Agriculture

Total geographical area of Pakistan is 79.61 million hectares (m.ha.). Area under cultivation is 21.59 m.ha.; of which, only 5.34 m.ha. (i.e., 25 percent) is free from soil limitations and is fit for intensive agriculture [Mian and Mirza (1993)]. The remaining agricultural lands have various types of problems including formation of slow permeability, water logging, salinity and sodicity, and wind and water erosion. Thus, on an average, three out of four hectares of cultivated land in Pakistan are in poor health. This in turn is causing temporary or permanent decline in the productive capacity of the land. Therefore, poor soil health is posing serious threat to the sustainable growth of agriculture.

Appendicocecal Fistula – A Rare Complication of Appendicitis

Fistulisation of appendix to other organs or to the exterior through abdominal wall is a rare complication of appendicitis. We present one such rare case of appendicocecal fistula due to appendicitis in a patient initially managed conservatively for appendicular lum

An Analysis of the Sources of Wheat Output Growth in the Barani Area of the Punjab

A time-varying efficiency effects approach using district level data of wheat in barani Punjab is used to disintegrate wheat output growth into different sources. The results show that wheat output grew at an annual rate of 2.71 percent under barani conditions, during the period of study. Technological change was the main driving force, sharing about 107 percent of this growth, while the changing inputs contributed negatively by about 10 percent and the efficiency contribution was less than 4 percent. On the other hand, irrigated output increased by about 4.7 percent per annum in the region; of which 65 percent, 1.3 percent, and 34 percent were attributable to technological change, change in efficiency, and increase in inputs. As regards the overall wheat output in the barani region of the Punjab, it grew at an annual rate of 2.97 percent—84 percent of which was shared by the barani lands and the remaining 16 percent was contributed by irrigated lands in the region. One common result which was observed under both barani and irrigated conditions was that the productivity growth (the sum of technological and efficiency change) showed declining trends exclusively due to negative trends in technical efficiency. Low relative profitability as compared to growing vegetables and raising livestock might be the main cause of this trend in the barani area: the same reason could also be a source of decline in efficiency. Rapid technological advancements require that farmers and administrators improve their management skills even to keep the productive efficiency at the same level. This is not possible without education and training along with a more effective flow of information [Lall (1993)]. Under these circumstances, the agricultural extension system has to play a greater role in assisting the farming community in the barani areas so as to adopt and use new technologies more rationally.

Factors that contribute to obesity problem among UTHM catering student

Negative perception by the society and the hospitality industry toward the disabled people is very high and it has to be changed and this parties should be given opportunity to work in this industry. Rosli, et al (2011) states the acceptance in the small and medium industries towards the disabled is at moderate level. However, in 2005, Ministry of Higher Education Malaysia (KPTM) has initiated Polytechnic Ibrahim Sultan, Johor Bahru conduct a pioneer program to produce graduates with disabilities (OKU) with hearing impairments for a career in the hotel industry. Related to the situation, some lecturers were sent to attend sign language courses for the preparation for the program, some facilities were updated to fit their needs. To this present Polytechnic Ibrahim Sultan, Johor Bahru has produced hundreds of OKU graduates. It is hope that the graduates produced from this program could reduce the number of foreign worker working in the industry. Dependence on foreign workers should be reduced because there are almost 2.6 million people with special needs in Malaysia. Some of them have been able to pursue their studies to diploma and Bachelor degrees. Through the development of education they are participated in, it is hoped that they will also contribute to the country's economy. The Government of Malaysia is in the effort to transform employers' perceptions towards this group to be more positive. Thus, several initiatives or benefits had been made by the Government of Malaysia to attract more government link companies (GLC) and private firms to hire people from this group. However there are also some challenges and obstacles faced by the industry in accepting these graduates at their company. Taheing (1996) states that in its study it has been able to identify problems that limit the employment of disabled persons including physiological factors, disability due to defects, occupational types, gender factors, workplace environment, personality, illness and other disabilities. This is a challenge and obstacle faced by the employer in hiring the disabled graduates in their industry. Therefore, the industry is highly concerned with the selection of highly capable employees in helping to increase profits to the company
