The archaeological mound of Sofalin south of the Alborz Mountains of Northern Iran (Eastern Rey plain) sheds considerablelight on at least four problems connected with the emergence of complex societies in this part of Iran. The first, it helpsfill a chronological gap in an important archaeological sequence by revealing a previously unidentified late fourth andthird millennium B.C. sequence of ...

in the present work an attempt has been made to study the effect of the twisted tapes as bed internals, on the performance of the gas-solid fluidized beds. experimental investigation has been carried out in cylindrical column with and without twisted tapes. twelve numbers of twisted tapes of three different widths with four values of the twist ratios for each width were studied at different sta...

Abstract: Lateral tape motion (LTM) in tape drives hinders accurate servo head positioning and can cause damage to the tape. It is one of the major obstacles to developing high density, high performance tape drives. This paper presents the development an active tape steering system to reduce LTM. A robust controller is designed using the Robust Bode (RBode) Plot, which translates an robust perf...

An alternative approach to applying entomopathogenic nematodes entails the distribution of nematodes in their infected insect hosts. Protection of the infected host from rupturing, and improving ease of handling, may be necessary to facilitate application. In this study our objective was to test the potential of a new method of formulating the infected hosts, i.e., enclosing the infected host i...

Patellar taping is a treatment adjunct commonly used in the management of anterior knee pain. The aim of this cross sectional study was to investigate the effects of medial glide patellar taping on sagittal plane lower-limb joint kinematics and knee pain during a unilateral squat in a symptomatic population complaining of anterior knee pain. Ten participants with a history of unilateral or bila...

/ This paper reports an assessment of various methods for sampling particulate surface contami^ nation for use in the field. The results from the study will be used to develop guidance for monitoring particulate surface contamination in the workplace. Three types of adhesive tape, two manual and two 'semi-automatic' wipe methods, and one Smair method were assessed. A field assessment of selecte...
