While T-C increases with increasing x (T-C = 118 K for x = 0 and T-C 363 K for x = 0.6), T* increases from 30 K (x 0) to 120 K (x = 0.4) and then decreases to 105 K (x = 0.5). The Delta S-m is negative around T-C and it decreases from Delta S-m = -6.2 Jkg(-1)K(-1) for x = 0 to -4.2 Jkg(-1)K(-1) for x = 0.6 for Delta H = 5 T. The inverse MCE occurs below T* and shows a maximum value of Delta S-m = +1.07 Jkg(-1)K(-1) at T = 10 K for Delta H = 5 T at x = 0.4. This

composition also shows a significant normal MCE (Delta S-m = 4 Jkg(-1)K(-1)) around T-C = 320 K, along with a high refrigeration capacity of 214 Jkg(-1), which makes it an interesting compound for room temperature magnetic refrigeration. The inverse MCE has been suggested to be caused by the learn more antiferromagnetic coupling between Sm 4f and Mn 3d moments. The coexistence of normal and inverse MCEs in a single material is interesting because the sample can Roscovitine nmr be cooled by adiabatic magnetization and demagnetization in different temperature regions, which will enhance the refrigeration

capacity. (C) 2011 American Institute of Physics. [doi:10.1063/1.3631074]“
“A new electromechanical mechanism for spinning core electrospun nanoyarn is researched, designed, and implemented. SEM images have shown that the deposited nanofibers were wrapped helically around the core filament resulting in a core electrospun nanoyarn. The parameters of this mechanism such as feed-in angles, twist rates, and take-up speeds are analytically investigated. Twist rates of 500 to 750 revolutions per minute, core feed-in angle of 0 degrees, and take-up speed of 1.5 cm/s were found optimum for

successfully producing core electrospun nanoyarn. This nanoyarn is expected to find many applications in industrial and medical textiles. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
“Accurate diagnosis of cerebral malaria (CM) is important for patient FG-4592 datasheet management, epidemiological and end point surveillance, and enrolling patients with CM in studies of pathogenesis or therapeutic trials. In malaria-endemic areas, where asymptomatic Plasmodium falciparum parasitemia is common, a positive blood film in a comatose individual does not prove that the coma is due to malaria. A retinopathy consisting of two unique features patchy retinal whitening and focal changes of vessel color – is highly specific for encephalopathy of malarial etiology. White-centered retinal hemorrhages are a common but less specific feature. Either indirect or direct ophthalmoscopy can be used to identify the changes, and both procedures can be learned and practiced by nonspecialist clinicians. In view of its important contributions to both clinical care and research, examination of the retina should become a routine component of the assessment of a comatose child or adult when CM is a possible diagnosis.
