We report a low temperature measurement technique and the magnetization data of a quantum molecular spin, by implementing an on-chip SQUID technique. This technique enables SQUID magnetometry in high magnetic fields, up to 7 T. The main challenges and the calibration process are detailed. The measurement protocol is used to observe quantum tunneling jumps of the S = 10 molecular magnet, Mn(12)-...
A method for measurement of betatron tune without the need for feedback-driven excitation has been developed at COSY. A bandlimited broadband noise source was used for beam excitation. The transverse beam position oscillation was then bunch-synchronously sampled and digitized with a high resolution ADC. The Fourier transform of the acquired data represents immediately the betatron tune. A funct...
The invariant cross section as a function of transverse momentum for antideuterons produced in 158A GeV/c per nucleon Pb+Pb central collisions has been measured by the NA44 experiment at CERN. This measurement, together with a measurement of antiprotons, allows for the determination of the antideuteron coalescence parameter. The extracted coalescence radius is found to agree with the deuteron c...
ین پایان نامه با هدف سنتز و شناسایی چهار نوع از نانو ذرات آغاز می شود. نانو ذرات آلوم اکسان از واکنش بوهمیت و کربوکسیلیک اسید مربوطه حاصل شدند. هدف از سنتز این نوع نانو ذرات ساخت غشاهای عامل دار شده با خاصیت آب دوستی و انتخاب پذیری جهت جداسازی روغن از مخلوط های آب و روغن، می باشد. tg-dta، ftir، sem، tem، uv/vis spectrophotometer، digital camera،contact angle measurement goniometer، ultrasonic b...
abstract the usage of heroin is associated with a variety of neurologic disorders, including acute transverse myelitis. in this study we present a 19 year old man who was suffered from insufflated heroin after several months of abstinence, and admitted to hospital emergency department, unconscious. he responded to fluid therapy and naloxone, but could not move his legs on examination. he had fl...
Narrow-access long-core cryogenic magnetometers enable measurement of a range of magnetic parameters at a speed and resolution that cannot be matched by other techniques. Despite the revolutionary impact that these instruments have had on paleomagnetic and environmental magnetic investigations, some fundamental constraints limit their usefulness. First, the pick-up coils have different response...
Accuracy of live ultrasound measurements to evaluate the total tissue depth (GR), as well as fat and LM depths at different scanning sites, was studied in 96 purebred Suffolk and Dorset lambs of both sexes slaughtered between 36 and 54 kg of BW. Before slaughter, 7 real-time ultrasound measurements were taken on lambs: fat and LM depths between the 12th and 13th ribs (transverse) and between th...
Inclusive measurement of J/Ψ (DELPHI), search for η b (ALEPH) and measurement of the cross-section of the double-tagged γγ events (ALEPH) are briefly overviewed. 1 Measurement of inclusive J/Ψ production in γγ events (DELPHI) The measurement of J/Ψ production in γγ interactions provides an insight into heavy quark production and also a possibility to study the gluon parton density of a resolved...
