Coupling between conduction electrons and localized magnetization is responsible for a variety of phenomena in spintronic devices. This coupling enables to generate spin currents from dynamical magnetization. Due to the nonlinearity of magnetization dynamics, the spin-current emission through the dynamical spin-exchange coupling offers a route for nonlinear generation of spin currents. Here, we...

Magnetization of large Nd-Fe-B sintered permanent magnets is still challenging. This type of permanent magnet is electrically conductive, so impulse magnetization causes a flow of eddy currents which prevent magnetization of the whole volume of the magnet. The paper deals with the impulse magnetization of sintered Nd-Fe-B permanent magnets and shows a method for the determination of suitable pa...

BACKGROUND Pedicled transverse rectus abdominis musculocutaneous flaps typically sacrifice the entire muscle. In our experience, the lateral strip of the rectus abdominis muscle can be spared in an attempt to maintain function and reduce morbidity. When the intercostal nerves are injured, muscle atrophy appears with time. The severed intercostal nerve was reinserted into the remnant lateral str...

Repeated pancreatectomy for pancreatic carcinoma is extremely rare. We report two such patients who underwent pancreatectomy for carcinoma developing in the pancreatic remnant after pylorus-preserving pancreatoduodenectomy (PpPD) for invasive pancreatic ductal carcinoma. One patient underwent PpPD for invasive pancreatic ductal carcinoma and received adjuvant chemotherapy. Follow-up computed to...

October 2004 marks the 400th anniversary of the sighting of SN 1604, now marked by the presence of an expanding nebulosity known as Kepler’s supernova remnant. Of the small number of remnants of historical supernovae, Kepler’s remnant remains the most enigmatic. The supernova type, and hence the type of star that exploded, is still a matter of debate, and even the distance to the remnant is unc...

The magnetization measurements at 5 K were carried out for Ni2Mn1 − xCuxGa (0 ≤ x ≤ 0.40) and Ni2MnGa1 − yCuy (0 ≤ y ≤ 0.25) alloys. All of the magnetization curves are characteristic of ferromagnetism or ferrimagnetism. By using Arrott plot analysis the spontaneous magnetization of all samples was determined from the magnetization curves. The magnetic moment per formula unit, μs, at 5 K was es...

Abstract Ag mixed Cd–Cu nanoferrite (Cd 0.5 Cu 0.25 Fe 2 O 4; Ag-CCF) has been successfully prepared by co-precipitation method. The grain size of ferrite was 10 nm estimated HRTEM; while the specific surface area measured BET 161 m /g. XRD measurement shows a good crystallization phase and FT-IR spectrum represents two characterized bands spinel 428 cm −1 596 . three broad peaks Raman 276 , 38...

Oesophageal replacement in patients following distal gastrectomy (DGE) remains a surgical challenge, and the standard option is the colonic or jejunal transplant. However, in some cases, it is possible (or mandatory) to utilize the remnant stomach for oesophagoplasty (EP). This method preserves some advantages of the gastric EP in comparison with the bowel EP. During recent years, several paper...

To define the roles, In vivo, of hepatic triglyceride lipase and lipoprotein lipase in the catabolism of trlglyceiide-rlch lipoproteins, we Investigated the relationship between the activities of the above enzymes In postheparin plasma and the fractional removal rates of very low density lipoproteins (VLDL) and VLDL remnant particles. In 22 patients, the fractional removal rates of VLDL and VLD...
