OBJECTIVE To measure serum cardiac troponin I (cTnI) concentrations in orphaned harbor seal (Phoca vitulina) pups at various points during rehabilitation in a seal rescue center and determine whether cTnI concentration was associated with survival during rehabilitation and duration of rehabilitation. DESIGN Serial cross-sectional study. ANIMALS Fifty-five 2- to 9-day-old harbor seal pups. PROCE...

purpose: the aim of this study was to compare the effects of a) a flame heated endo plugger, b) gatesglidden drills and c) gpx drills on the apical seal for the purpose of post space preparation. materials & methods: the crowns of sixty six extracted maxillary central teeth were removed from cej by a diamond disc and the root canals were prepared and obturated with guttapercha and sealer (ah26)...

statement of problem: when a tooth is treated endodontically, there are several objectives, which must be met for the root canal therapy to be successful. one of those objectives is the complete obturation of the root canal system. purpose: the purpose of this study was to evaluate the apical sealability of the theramfil endodontic obturation technique and compared it with lateral condensation....

OBJECTIVE To evaluate and compare the efficacy of an oscillating-rotating (O-R) power toothbrush with a brush head utilizing angled bristles to a marketed sonic toothbrush in the reduction of plaque and gingivitis over an eight-week period. METHODS This study used a randomized, examiner-blind, single-center, two-treatment, parallel group, eight-week design. Subjects with mild-to-moderate plaq...

While millings materials from old pavement surface can be an important component of cost effective maintenance operation, their use in maintenance projects are not uniform and well documented. This study documents the different maintenance practices followed by four transportation districts of New Mexico Department of Transportation (NMDOT) in an attempt to find whether millings are being used ...

We report on the design of Scream, a new software-efficient stream cipher, which was designedto be a “more secure SEAL”. Following SEAL, the design of Scream resembles in many ways ablock-cipher design. The new cipher is roughly as fast as SEAL, but we believe that it offers asignificantly higher security level. In the process of designing this cipher, we re-visit the SEALdesign...

BACKGROUND Placing chest tubes to water seal is superior for patients with an air leak, but when a patient has a pneumothorax and an air leak the best chest tube setting is unknown. METHODS This is a retrospective analysis of a prospective database on a consecutive series of patients who had a pneumothorax and air leak on the same day. Patients underwent elective pulmonary resection by one su...

We introduce the concept of a quantum “seal” and investigate its feasibility. We define a seal as a state provided by Alice to Bob along with a set of instructions which Bob can follow in order to “break the seal” and read the classical message stored inside. We define two success criteria for a seal: the probability Bob can successfully read the message if he follows Alice’s instructions witho...
