Abstract:

To investigate the influence of [Na+] in sweat on the distribution of body water during dehydration, we studied 10 volunteer subjects who exercised (40% of maximal aerobic power) in the heat [36 degrees C, less than 30% relative humidity (rh)] for 90-110 min to produce a dehydration of 2.3% body wt (delta TW). After dehydration, the subjects rested for 1 h in a thermoneutral environment (28 degrees C, less than 30% rh), after which time the changes in the body fluid compartments were assessed. We measured plasma volume, plasma osmolality, and [Na+], [K+], and [Cl-] in plasma, together with swe

Abstract:

In high-speed sampling, in terms of the shift operator <I>z</I>, digital control algorithms easily become numerically illconditioned. In such situations, control algorithms based on the delta operator <I>δ</I> are useful. However, when the delta operator <I>δ</I> is applied to a control algorithm based on fixed-point arithmetic, coefficient quantization errors and product quantization errors appear. As a result, the control algorithm again becomes numerically ill-conditioned. To solve this problem, a modified delta operator <I>δ'</I> is proposed.

Abstract:

This paper deals with the special replacement of the shift operator and its associated z transform by delta operator and ? transform, respectively. The aim of the paper is to clarify the role of zeros of discretized linear single input single output continuous-time systems modeled by shift and delta operators. In particular, the effect of zero dynamics on the control system design based on classical pole-zero assignment in the case of both operators is considered. The analysis is illustrated by simulation results.

One of the key issues of the Source-to-Sink process is revealing the geomorphological evolutions of large rivers from the perspective of river sink areas.

Heavy minerals and zircon geochronology in the Plio-Pleistocene sediments of the vertex of the modern Yangtze delta (core RGK15) reveal that a significant provenance shift occurred at ~2.6 Ma (the beginning of the Pleistocene).

Abstract:

In this paper we calculate the particle creation as seen by a stationary observer in an anisotropic universe. By using an observer and geometry dependent time to quantize a massive scalar field we show that a discrete energy spectrum shift occurs. The length scale associated with the geometry provides the energy scale by which the spectrum is shifted. The β(p, q) coefficient for the Bogolubov transformation calculated is proportional to a series of delta functions whose argument contains p and q and half multiples of the root of the curvature.

In our proposed technique the wavelength shift of FBG can be determined by change of lasing wavelength of distributed feedback laser (DFB-laser) due to the change of laser substrate temperature.

Abstract Background Because traditional QC is discontinuous, laboratories use additional strategies to detect systematic error. One strategy, the delta check, is best suited to detect large systematic error. The moving average (MA) monitors the mean patient analyte value but cannot equitably detect systematic error in skewed distributions. Our study combines delta check and MA to develop an average of deltas (AoD) strategy that monitors the mean delta of consecutive, intrapatient results.

AbstractThe power spectra of several δ Scuti stars show close peaks with similar frequencies and amplitudes. Apart from possible observational problems, this can be interpreted in terms of two separate pulsation modes with similar, close frequencies or an artifact of amplitude variability of a single pulsation mode. If sufficient data are available, it is possible to distinguish between the two hypotheses on the basis of expected systematic phase changes associated with the amplitude variations of an assumed single frequency.

The activity of microsomal delta 12-desaturase in Acanthamoeba castellanii was increased after growing cultures were chilled from the optimal growth temperature (30 degrees C) to 15 degrees C.

The increase in activity on chilling was greatly reduced when protein synthesis was blocked before the temperature shift. Thus the major mechanism for the induction of delta 12-desaturase is increased protein synthesis. delta 12-Desaturase activity was higher

The lens-specific proteins alpha and delta crystallins and lentoid bodies, structures that follow a differentiation pathway similar to that of the lens, regularly appear after 4 to 5 weeks in quail embryo neuroretina monolayer cultures.

Abstract:

The lens-specific proteins alpha and delta crystallins and lentoid bodies, structures that follow a differentiation pathway similar to that of the lens, regularly appear after 4 to 5 weeks in quail embryo neuroretina monolayer cultures. We have investigated the effects of the avian oncogenic retroviruses Mill Hill 2 and Rous sarcoma virus on this process. Quail embryo neuroretina cells transformed by Mill Hill 2 virus were established into permanent cultures that synthesized alpha and delta crystallins and contained stem cells for the production of lentoid bodies.

Abstract:

Fluid redistribution in isolated perfused cat calf muscle caused by rapid increases in plasma osmolality was studied using NaCl or sucrose. Extracellular tracers (51Cr-labeled EDTA or [3H]mannitol) were added to the perfusate 90 min before solutes were added, and samples were taken from plasma immediately before osmolality was increased and 17, 40, and 65 min later. Interstitial fluid volume (IFV) was calculated as extracellular volume (ECV) minus plasma volume (Evans blue dye). Total tissue water changes (delta TTW) were measured by continuous recording of tissue weight. Change in intracellul

Abstract:

We have previously shown that the delta E3 site is an essential element for transcriptional activation by the human T-cell receptor (TCR) delta enhancer and identified two factors, NF-delta E3A and NF-delta E3C, that bound to overlapping core (TGTGGTTT) and E-box motifs within delta E3. In this study, we show that protein binding to the core motif is necessary but not sufficient for transcriptional activation by the delta E3 element. In contrast, protein binding to the E-box motif does not contribute significantly to enhancer activity. A similar core motif present within the enhancers of T-cel

Abstract:

Phorbol ester and alpha 1-adrenergic stimulation of Na-Cl-K cotransport in human tracheal epithelial cells was investigated by determining the expression of protein kinase C (PKC) isotypes and their activation by phorbol 12-myristate 13-acetate (PMA) and methoxamine, an alpha 1-adrenergic agonist. PKC-alpha, -beta II, -delta, -epsilon, and -zeta were expressed in confluent cell cultures. PKC-beta I, -gamma, and -eta were not detected. PKC-alpha and -zeta were localized to the cytosol, and PKC-beta II and -delta were distributed approximately evenly between cytosolic and particulate fractions.

Abstract:

The extent to which the end-systolic volume (ESV) “follows” the end-diastolic volume (EDV) when the latter changes in response to various perturbations is a major determinant of the cardiac ejection fraction (EF) and has not been studied in humans. We measured EDV, ESV, and EF, determined by gated blood pool scans, during a change in posture from the supine to the upright seated position and during graded upright bicycle exercise. The experimental group consisted of 119 healthy individuals (79 males and 40 females) ranging in age from 21 to 81 yr and in physical-conditioning status (75–225 W m

Abstract:

Current planning and legislation in California’s Sacramento-San Joaquin Delta call for the large-scale ecological restoration of aquatic and terrestrial habitats. These ecological mandates have emerged in response to the region’s infrastructural transformation and the Delta’s predominant use as the central logistical hub in the state’s vast water conveyance network. Restoration is an attempt to recover what was externalized by the logic and abstractions of this logistical infrastructure. However, based on findings from our research, which examined how people are using restored and naturalized

Abstract:

We examined the possibility that Na+ current (INa) may play a role in excitation-contraction coupling in cat ventricular myocytes. A voltage step from -70 to -40 mV produced a fast INa, followed by a small transient inward current, a brief loss in voltage control to more positive potentials, and a transient contraction (reduction in cell length, delta L). We established that 10 microM nifedipine completely blocked Ca2+ current but did not prevent delta L; nifedipine reduced it by approximately 15%. This nifedipine-insensitive delta L was abolished by 1-10 microM ryanodine, 1-10 microM saxitoxi

This paper aims to understand how T-learning helps communities achieve better sustainability outcomes. On the basis of an intensive literature review and field research conducted in the Mekong Delta of Vietnam, the paper proposes a substantial linkage between T-learning and sustainability. It first outlines the environmental changes in Vietnam’s Mekong Delta, which appear to serve as “disorienting dilemmas” that force local people to learn and gradually shift their farming practices to align with a climate-resilient development. The paper relies on the outcomes of household surveys, field obse
