A new study of shower age distribution in near vertical showers by EAS air shower array

The air shower array has been developed since it started operation in 1931. The array covering an area of 900 sq m now incorporates 21 particle density sampling detectors around two muon magnetic spectrographs. The air showers are detected in the size range 10 to the 4th power to 10 to the 6th power particles. A total of 11000 showers has so far been detected. Average values of shower age have been obtained in various shower size ranges to study the dependence of shower age on shower size. The core distance dependence of shower age parameter has also been analyzed for presentation

A new study of muons in air showers by NBU air shower array

The North Bengal University (NBU) air shower array has been in operation in conjunction with two muon magnetic spectrographs. The array incorporates 21 particle density sampling detectors around the magnetic spectrographs covering an area of 900 sq m. The layout of the array is based on the arrangement of detectors in a square symmetry. The array set up on the ground level is around a 10 m high magnetic spectrograph housing. This magnetic spectrograph housing limits the zenith angular acceptance of the incident showers to a few degrees. Three hundred muons in the fitted showers of size range 10 to the 4th power to 10 to the 5th power particles have so far been scanned and the momenta determined in the momentum range 2 - 440 GeV/c. More than 1500 recorded showers are now in the process of scanning and fitting. A lateral distribution of muons of energy greater than 300 MeV in the shower size range 10 to the 5th power to 7 x 10 to the 5th power has been obtained

Non-fusion joining of aluminium

JOINING of aluminium is now a well established techn-ology. Successful joining can be done by TIG and MIG welding, pressure welding processes, brazing and solde-ring processes. Conventional fusion processes of joining aluminium are well known and are widely used in India by all major fabricators. On the other hand, though non-fusion joining processes like soldering, brazing and pressure welding have wide field of applications the correct process and material required are not very well known ; as such there is a specific need in India, at present, to disseminate the knowledge on joining of aluminium especially by these processes which a small fabricator can handle

Implementation and Impact of ISO 9001

__Abstract __ The ISO 9001 quality management standard has been implemented by more than one million organizations in 187 countries since its introduction in 1987. A newer version of ISO 9001 is planned to be introduced in 2015. Even though it is widely used by organizations to gain both operational and market benefits, the studies on the impact of ISO 9001 report mixed findings. Therefore, the aim of this dissertation is to find out what is the impact of ISO 9001, and to better understand the differences in current literature. The findings demonstrate that ISO 9001 leads to operational and market benefits in the majority of cases. We also show that the benefits gained from ISO 9001 differs depending on the length of the period since certification, standard version, geographic location, industry sector, and company size. We further demonstrate that national differences, specifically the level of economic development and national culture, impact the performance benefits of ISO 9001. Moreover, we find that not all of the employees in a company use ISO 9001 in their daily work. Having a positive attitude towards ISO 9001 usage, being aware of ISO 9001, believing that ISO 9001 is useful and easy to use, and feeling responsible for ISO 9001 discriminated employees that did participate in ISO 9001-related practices from those that did not. Together, these three chapters illustrate that the relationship between ISO 9001 and business performance is not as straightforward as it is often assumed. Our findings indicate that the implementation and the impact of ISO 9001 can be studied and explained at three different levels: Country level, company level and employee level
