Abstract:

O trabalho de Einstein intitulado Sobre o teorema quântico de Sommerfeld e de Epstein [1,2], publicado em 1917, propõe uma generalização da regra de quantização de Bohr, Sommerfeld e Epstein para sistemas multidimensionais integráveis. Ao mesmo tempo, Einstein nota que sistemas não-integráveis não podem ser quantizados dessa maneira. Essa observação indica pela primeira vez a não trivialidade do limite semiclássico de sistemas caóticos, e pode ser considerado como pioneiro da teoria de caos quântico.

O maior dos desafios para as empresas tem sido a tentativa (freqüentemente mal-sucedida) de acompanhar a evolução de seus ambientes. Tamanha dificuldade se deve a dois fatores: primeiro, as empresas desejam sempre chegar a algum estado de estabilidade, acreditando ser isto possível pela adaptação às mudanças ocorridas no ambiente externo (princípio do retorno ao equilíbrio); segundo, acredita-se também que decisões e ações conduzam aos resultados previstos (princípio da linearidade causa-efeito).

The ELISA for CAgs was the first parameter to give a positive result but the detection was limited only to day 2 p.i.

Abstract Extreme weather events such as cold-air outbreaks (CAOs) pose great threats to human life and the socioeconomic well-being of modern society. In the past, our capability to predict their occurrences has been constrained by the 2-week predictability limit for weather. We demonstrate here for the first time that a rapid increase of air mass transported into the polar stratosphere, referred to as the pulse of the stratosphere (PULSE), can often be predicted with a useful degree of skill 4–6 weeks in advance by operational forecast models. We further show that the probability of the occur

During hypovolemia, reflex increases in mesenteric arterial tone may preferentially reduce gut blood flow so that the onset of O2 supply dependence occurs in the gut before other regions.

Germination failed to occur in lupin seeds exposed to waterlogged soil, and survival was reduced to 0% after 4 days waterlogging.

This suggested that lack of O2 may limit growth of lupin seeds in waterlogged soil. Germination and hypocotyl elongation were also significantly increased on moist filter paper in Petri dishes when seeds were coated with CaO2. Adding streptomycin alone did not increase germination or survival of lupins under waterlogged conditions. Resul

When the power is needed, turboexpanders connected to generators convert the compressed air back into electrical energy.

Introduction. Complementary and alternative medicines (CAMs) are commonly used among lactating women, despite the poor knowledge of these products and of their safety. Perception of pregnancy- and breastfeeding-related difficulties and consequent use of CAMs may differ in bereaved women, by force of the distress related to previous loss, although no literature evidence is available. This Herbal supplements in Breastfeeding InvesTigation (HaBIT) post hoc analysis explored the impact of previous pregnancy loss on lactating behaviors and on use of CAMs during breastfeeding.

Abstract:

AbstractHER3 is highly expressed in luminal breast cancer subtypes. Its activation by NRG1 promotes activation of AKT and ERK1/2, contributing to tumour progression and therapy resistance. HER3-targeting agents that block this activation, are currently under phase 1/2 clinical studies, and although they have shown favorable tolerability, their activity as a single agent has proven to be limited. Here we show that phosphorylation and activation of HER3 in luminal breast cancer cells occurs in a paracrine manner and is mediated by NRG1 expressed by cancer-associated fibroblasts (CAFs). Moreover,

Abstract:

Background: The Classroom-as-Organization (CAO) is an experiential learning course in which students create and manage an organization as part of class activities. Student interaction with peers is an important feature of the CAO. Educators suggested that student interactions in CAOs follow certain patterns, but these observations have not been tested in empirical research. Purpose: The research focused on exploring patterns of interaction in a CAO. Methodology/Approach: Network data were collected from students and instructors at four different times during a two-semester CAO course. The auth

Abstract:

ABSTRACT Introduction Phosphoinositide 3-kinase (PI3K) inhibitors are a new class of cancer therapeutics that inhibits one or more enzymes in the PI3K/AKT/mTOR tumor growth pathway. As compared to other tyrosine kinase inhibitors, there is evidence that PI3K inhibitors have a higher incidence of severe cutaneous adverse events (CAEs) ranging from 2-21%. There is a lack of further characterization of clinical trials and management options for these CAEs.

Presented in this article are closed-form kinematic equations that give the minimum cycle time for multiple-dwell cam-follower systems subject to acceleration and jerk constraints set by the user. Cam-driven machines are used extensively in manufacturing because of their low cost, great precision and high production rates when compared with alternatives. Since they are frequently used in mass production operations, there is a need for minimizing their cycle time to increase manufacturing throughput and reduce capital costs for machines and facilities. Their widespread use means that there is t

Daminozide (succinamic acid 2, 2-dimethylhydrazide) fortified solutions (12.5 ppm) containing 50mM NaH2PO4 and 24% sucrose (w/w) were adjusted to pH 3.0, 3.6, or 4.0 and either heated (100°C) for 0, 5, 10, or 15 min in sealed cans and cooled or heated (80°C) for 0, 5, or 10 min in open cans, sealed, heated (100°C) for 5 min, and cooled. Daminozide degradation due to heating was less than the HPLC detection limit (1.5 ppm) for all of the treatments.

The emulsification was performed by the ultrasonic irradiation. The microextraction procedure was carried out in a 27 ml special tube. It was equipped with the capillaries for sampling the extract and an air outlet. A salting-out additive (Na2SO4) was used to reduce the solubility of MTBE in water and to increase the extraction efficiency of CAAs. The air passage through the emulsion of the extractant was carr

Asthma is a chronic, inflammatory lung disease affecting around 235 million people worldwide. Conventional medications in asthma are not curative and patients have significant concerns regarding their side-effects. Consequently, many asthma patients turn to complementary and alternative medicine (CAM) for a more holistic approach to care. We systematically reviewed the available evidence on the effectiveness of CAM in the management of asthma in adults.We searched the MEDLINE, EMBASE, CINAHL, AMED and Cochrane databases for randomised controlled trials published in English between 1990 and 201

Abstract:

Cancer-associated fibroblasts (CAFs) can either suppress or support T lymphocyte activity, suggesting that CAFs may be reprogrammable to an immunosupportive state. Angiotensin receptor blockers (ARBs) convert myofibroblast CAFs to a quiescent state, but whether ARBs can reprogram CAFs to promote T lymphocyte activity and enhance immunotherapy is unknown. Moreover, ARB doses are limited by systemic adverse effects such as hypotension due to the importance of angiotensin signaling outside tumors. To enhance the efficacy and specificity of ARBs in cancer with the goal of revealing their effects o

Abstract:

Like in an ecosystem, cancer and other cells residing in the tumor microenvironment engage in various modes of interactions to buffer the negative effects of environmental changes. One such change is the consumption of common nutrients (such as glutamine/Gln) and the consequent accumulation of toxic metabolic byproducts (such as ammonium/NH4). Ammonium is a waste product of cellular metabolism whose accumulation causes cell stress. In tumors, it is known that it can be recycled into nutrients by cancer associated fibroblasts (CAFs).
