Abstract. Reconstructing precipitation and wind from the geological record could help researchers understand potential changes in dynamics response to climate change Peru. The last deglaciation offers natural experimental conditions test of high-latitude forcing. While considerable research has been done reconstruct variability during Atlantic sector South America, Pacific America received litt...

INTRODUCTION Several prior studies have examined the impact of learners (medical students or residents) on overall emergency department (ED) flow as well as the impact of resident training level on the number of patients seen by residents per hour. No study to date has specifically examined the impact of learners on emergency medicine (EM) attending physician productivity, with regards to patie...

Quenching of pyrene fluorescence by oxygen was used to determine oxygen diffusion coeffÉcients in phospholipid dispersions and erythrocyte plasma membranes. The fluorescence intensity and lifetime of pyrene in both artificial and natural membranes decreases about 80 % in the presence of 1 atm O, , while the fluorescence excitation and emission spectra and the absorption spectrum are unaltered. ...

Primality test, prime In this paper we prove the following simplification of Miller's primality criterion [2]. Theorem 1. Assume that for every integer d that is 1 mod 4 and either prime or the product of two primes, the L-function I= & (k/d) l kmS satisfies the generalized Riemann hypothesis, where {kid) denotes the Jacobi symbol, defined below. Let n be an odd integer, n > I , and write n-I-=...

We describe a noninvasive method for determining end-systolic meridional and circumferential wall stress and left ventricular architecture as the ratio of muscle to cavity area. With this technique, which uses two-dimensional echocardiography and cuff-determined values for systolic blood pressure, we assessed wall stress and left ventricular architecture in 15 normal subjects and 15 asymptomati...

Site-directed mutagenesis is a widely used technique in molecular biology to generate single or multiple exchanges, insertions or deletions in DNA sequences. A number of strategies have been developed and used successfully (2,4). The QuikChange Site-Directed Mutagenesis Kit (Stratagene, La Jolla, CA, USA) has proven valuable because it consistently yields high mutagenesis efficiencies and uses...

The potential of using Effective Microorganisms (EM) to purify waste water, including that of a sewage system, for recycling purposes was evaluated. The studies were extended to examine the potential of using treated sewage sludge as a fertilizer in crop production. Long term application of EM reduced the adverse characteristics of waste water. The quality of the treated water was high, which i...

Compliant sheet metal assembly is a hierarchical manufacturing process that plays a significant role in automotive product development. Parts are joined in different stations to form the final product (e.g., the vehicle body structure). Dimensional variation is a product attribute of major importance that characterizes quality, and is mainly affected by the variability of parts, fixtures, and j...

Retroviral-mediated delivery of the P140K mutant O-methylguanine-DNA methyltransferase (MGMT) into hematopoietic stem cells (HSC) has been proposed as a means to protect against dose-limiting myelosuppressive toxicity ensuing from chemotherapy combining O-alkylating agents (e.g., temozolomide) with pseudosubstrate inhibitors (such as O-benzylguanine) of endogenous MGMT. Because detoxification o...
