In this paper, a low voltage bandgap reference circuit has been proposed. The introduction of modified beta multiplier bias decreased the mismatch caused by PMOS transistors opamp contribution. By shifting fixed resistors to NMOSs drain side, minimised threshold between two NMOS transistors. A 200-point MC simulation showed 0.9 mV standard deviation, with 0.34% accuracy. simulated temperature c...

we investigate the temperature-dependences of the Brillouin frequency shift in three different kind of single-mode fibers using a heterodyne method for sensing temperature. Positive dependences coefficients of 0.77, 0.56 and 1.45MHz/0C are demonstrated for 25 km long single-mode fiber, 10 km long non-zero dispersion shifted fiber and 100 m photonic crystal fiber, respectively. The results indic...

There is a large amount of enrichment rare earth elements in Zhungeer coal and ash, making it possible to use fly ash as source for industrial production elements. In order optimize the leaching process increase rate, circulating fluidized bed Power Plant was used material, single factor test orthogonal were influence rate acid The factors discussed, results showed that when 3mol/L hydrochloric...

The responses of rectal temperature (RT), respiratory rate (RR) and heart rate (HR) of ostrich (struthio camelus) chicks during road transportation were investigated using standard recording procedures. The RT and RR of the ostriches increased significantly (P<0.05) from 39.5 ± 0.1 0C and 12.2 ± 2.0 breaths per minute (bpm), respectively, before transportation, to 40.2 ± 0.3 0C and 50.7 ± 9.1 b...

This study examines the fatigue and anisotropy behaviour of cold rolled AA1200 aluminium alloy for light weight automotive connecting rod application. Aluminium (Al) 1200 ingots were melted at temperature of 680 0C (after one hour of heating) cast in sand mould and cast samples homogenized for 6 hrs at 480 0C. The cold rolling process was carried out after homogenisation for 10, 20, 30, 40 and ...

Ilemodynamic and echocardiographic measurements were obtained in 15 patients prior to cardioversion and immediately, one, three, and five hours after ca ,dioversion of atrial fibrillation to normal sinus rhythm1z4. j ve hours after cardioversion, there was improvement in cardiac index (P < 0.005), in stroke index (P <0.005)1and i11 stroke work index (P < 04)25), but no significant change in hea...

The purpose of this project is to examine cyclic voltammetry (CV) analytical technique for anti_thalassemia drug deferasirox by modified multi-walled carbon nanotubes (MWCNTs) on glassy electrod (GCE) was described. electrochemical performance studied technique. ability the electrode determination under Optimize condition in pH 13.8~14, scan rate 100mv/s, temperature 30 0C and interference that...

A new source mechanism is proposed for the 'reflected' ion beams observed in the foreshock region of the earth's bow shock. In our model the beams originate in the magnetosheath downstream of the quasi-perpendicular portion of the shock. The quasi-perpendicular shock transition is characterized by two downstream ion populations including high-energy gyrating ions in addition to the directly tra...

Kinema was prepared by using the pure culture of Bacillus subtilis laboratory and traditional method. Now both these two kinema were dried in a batch type tray drier at (65-70)0C for (8-10) hours to fine powder. The chemical analysis powder method found as 6.79%, 21.45%, 42.91%, 4.84%, 24.01% 7.218%, 20.624%, 41.99% and4.17%, 25.998% terms moisture content, fat, protein, total ash, carbohydrate...
