Performance Characteristics of Personal Samplers in Still and Moving Air

Personal samplers or in general blunt body samplers are widely used in occupational hygiene for collecting air contaminants in the work environments. This work is part of an ongoing research into the performance evaluation of personal samplers, particularly in terms of their aerodynamic properties. Velocity profiles have been measured around and within typical cylindrical sampling devices, ...

effect of bataine and sulphate supplement on wool and milk characteristics and lambs performance in naine ewes

تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...

Comparative Review of the Performance Based Design of Building Structures Using Static Non-Linear Analysis, Part A: Steel Braced Frames

The objective of this review to be submitted in two independent parts, for steel frames and for RC frames, is to compare their structural performance with respect to the proposed N2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. A preliminary investigation is presented on a pushover analysis used for the seismic perf...

Static Performance of a . . .

A m ultiaxis thrust-vectoring nozzle designed to have equal ow-turning capability in pitch and yaw was conceived and experimentally tested for internal static performance at Langley Research Center. The cruciform-shaped, convergent-divergent nozzle turned the ow for thrust vectoring by deeecting the divergent surfaces of the nozzle, called aps. Methods for eliminating physical interference betw...
