Cobalt ferrite (CoFe2O4) possesses excellent chemical stability, good mechanical hardness and a large positive first order crystalline anisotropy constant, which made this ferrite a promising candidate for magneto-optical recording media. In addition to precise control on the composition and structure of CoFe2O4, the success of its practical application will depend on the capability of controll...

Using combined resonance and ultrasonic methods, a full set of material constants has been measured for morphotropic phase boundary (MPB) composition xPb(In(12)Nb(12))O(3)-(1-x-y)Pb(Mg(13)Nb(23))O(3)-yPbTiO(3) (PIN-PMN-PT) single crystals poled along [001](c). Compared with the MPB composition (1-x)Pb(Mg(13)Nb(23))O(3)-xPbTiO(3) (PMN-PT) single crystals, the PIN-PMN-PT single crystals have smal...

1337 although the scientific evidence is inconclusive. Problems associated with prophylactic antibiotics include selection of more resistant organisms, the development of resistant bacteria, allergic reactions, and expense. Most surgeons who give preoperative antibiotics use a broad-spectrum, relatively nonsensitizing drug for 1–3 days before surgery. The most common source of endophthalmitis i...

OBJECTIVES To investigate sexual practices and risk factors for prevalent HIV infection among young men in Kisumu, Kenya. GOAL The goal of this study was to identify behaviors associated with HIV in Kisumu to maximize the effectiveness of future prevention programs. STUDY DESIGN Lifetime sexual histories were collected from a nested sample of 1337 uncircumcised participants within the conte...

t u C T c bstract he purpose of this study was to evaluate the topogaphy of new and used ProTaper rotary nickel-titanium NiTi) instruments by using atomic force microscope. our new and four used size S1, S2, F1, and F2 instruents were selected for this study. New and used nstruments were analyzed on 11 points along a 3-mm ection at the tip of the instrument. Quantitative meaurements according t...

Methods: OPs were recorded from a comeal lens, after Ganzfeld stimulation. The analog recording bandwidth was set to IO@1Khz. OPs were acquired following three difrerent protocols: 1) immediately after an abmot change in background illumination, 2) followina various time of preahaptation and 3) duhng the adaptation period. Purpose: The Visual Evoked Potential (VEP) crossed asymmetry revealed in...

This study examines the legal power of nominee agreements and basis judge consideration in deciding adjudicating cases related to agreements. The research method used is normative method. approach a statutory approach, conceptual case approach. results obtained that, first that agreement has no force because it does not meet validity an contained Article 1320 Civil Code (KUHPerdata) break 1335 ...

RNA-protein cross-links were introduced into E. coli 30S ribosomal subunits by treatment with methyl p-azidopEenyl acetimidate. After partial nuclease digestion of the RNA moiety, a number of cross-linked RNA-protein complexes were isolated by a new three-step procedure. Protein and RNA analysis of the individual complexes gave the following results: Proteins S3, S4, S5 and S8 are cross-linked ...
