Microwave photovoltage and photoresistance effects in ferromagnetic microstrips

We investigate the dc electric response induced by ferromagnetic resonance in ferromagnetic Permalloy (Ni80Fe20) microstrips. The resulting magnetization precession alters the angle of the magnetization with respect to both dc and rf current. Consequently the time averaged anisotropic magnetoresistance (AMR) changes (photoresistance). At the same time the time-dependent AMR oscillation rectifies a part of the rf current and induces a dc voltage (photovoltage). A phenomenological approach to magnetoresistance is used to describe the distinct characteristics of the photoresistance and photovoltage with a consistent formalism, which is found in excellent agreement with experiments performed on in-plane magnetized ferromagnetic microstrips. Application of the microwave photovoltage effect for rf magnetic field sensing is discussed.Comment: 16 pages, 15 figure

Embankment Design in Seismic Areas — Indian Practice

A number of river valley projects for the development of water and power resources, particularly in the Northern and North Eastern part of India, lie on the foothills of Himalayas which is seismically active. In the developmental activity of dam building, aseismic design of dam is therefore recognized and adopted. The paper presents the current Indian practice in the aseismic design of embankment dams with illustrations from studies carried out on some recent dams

On the line shape of the electrically detected ferromagnetic resonance

This work reviews and examines two particular issues related with the new technique of electrical detection of ferromagnetic resonance (FMR). This powerful technique has been broadly applied for studying magnetization and spin dynamics over the past few years. The first issue is the relation and distinction between different mechanisms that give rise to a photovoltage via FMR in composite magnetic structures, and the second is the proper analysis of the FMR line shape, which remains the "Achilles heel" in interpreting experimental results, especially for either studying the spin pumping effect or quantifying the spin Hall angles via the electrically detected FMR.Comment: 14 pages, 9 figure

MOLECULAR CHARACTERIZATION OF MMP-9 GENE IN CYSTIC FLUID OF CYSTICERCUS TENUICOLLIS BY REVERSE TRANSCRIPTION POLYMERASE CHAIN REACTION (RT-PCR)

ABSTRACT The present study was carried out to confirm the presence of MMP-9 gene in the cystic fluid of Cysticercus tenuicollis. Collection of cyst was made from goats slaughtered at local abattoirs and washed thoroughly with PBS (pH 7.4). The cystic fluid was aspirated, centrifuged at 10,000 rpm for 15 minutes at 4°C and the supernatants were used for further study. Total RNA was isolated from the cystic fluid of Cysticercus tenuicollis. The total cellular RNA was obtained from 400 µL of cystic fluid was 0.214 µg and the concentration of the RNA was 0.535 µg/mL. The RT-PCR product, 204 bp propeptide domain of MMP-9 was detected through agarose gel electrophoresis, which confirmed the presence of MMP-9 in the cystic fluid of Cysticercus tenuicolli

A high energy gamma camera using a multiple hole collimator and PSPMT

A high energy gamma camera using a parallel hole tungsten collimator and a 7.62 cm square Position Sensitive Photomultiplier Tube (PSPMT) has been assembled and tested. The measured energy resolution is 12-20% FWHM for 137Cs (662 keV) gamma rays, and 17-23% FWHM for 57Co (122 keV). The measured spatial resolution measured is 2.8-3.2 mm for 122 keV and 3.4-5.3 mm for 662 keV. The variation in the energy and spatial resolution is due to the continuously varying gain across the PSPMT. Measured energy spectra and images obtained are presented.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31118/1/0000014.pd

Concomitant Carcinoma in situ in Cystectomy Specimens Is Not Associated with Clinical Outcomes after Surgery

Objective: The aim of this study was to externally validate the prognostic value of concomitant urothelial carcinoma in situ (CIS) in radical cystectomy (RC) specimens using a large international cohort of bladder cancer patients. Methods: The records of 3,973 patients treated with RC and bilateral lymphadenectomy for urothelial carcinoma of the bladder (UCB) at nine centers worldwide were reviewed. Surgical specimens were evaluated by a genitourinary pathologist at each center. Uni- and multivariable Cox regression models addressed time to recurrence and cancer-specific mortality after RC. Results: 1,741 (43.8%) patients had concomitant CIS in their RC specimens. Concomitant CIS was more common in organ-confined UCB and was associated with lymphovascular invasion (p < 0.001). Concomitant CIS was not associated with either disease recurrence or cancer-specific death regardless of pathologic stage. The presence of concomitant CIS did not improve the predictive accuracy of standard predictors for either disease recurrence or cancer-specific death in any of the subgroups. Conclusions: We could not confirm the prognostic value of concomitant CIS in RC specimens. This, together with the discrepancy between pathologists in determining the presence of concomitant CIS at the morphologic level, limits the clinical utility of concomitant CIS in RC specimens for clinical decision-making.

Assessment of clinical outcomes in patients with fibromyalgia: Analysis from the UK Medical Cannabis Registry.

INTRODUCTION: There are limited therapeutic options for individuals with fibromyalgia. The aim of this study is to analyze changes in health-related quality of life and incidence of adverse events of those prescribed cannabis-based medicinal products (CBMPs) for fibromyalgia. METHODS: Patients treated with CBMPs for a minimum of 1 month were identified from the UK Medical Cannabis Registry. Primary outcomes were changes in validated patient-reported outcome measures (PROMs). A p-value of <.050 was deemed statistically significant. RESULTS: In total, 306 patients with fibromyalgia were included for analysis. There were improvements in global health-related quality of life at 1, 3, 6, and 12 months (p < .0001). The most frequent adverse events were fatigue (n = 75; 24.51%), dry mouth (n = 69; 22.55%), concentration impairment (n = 66; 21.57%), and lethargy (n = 65; 21.24%). CONCLUSION: CBMP treatment was associated with improvements in fibromyalgia-specific symptoms, in addition to sleep, anxiety, and health-related quality of life. Those who reported prior cannabis use appeared to have a greater response. CBMPs were generally well-tolerated. These results must be interpreted within the limitations of study design
