TL;DR: Managing SDS can involve several practices such as relieving soil compaction, delaying planting, and selecting soybean products with a good disease tolerance package.
Abstract:  Sudden death syndrome (SDS) is one of the most important diseases of soybean in North and South America.  Soybeans are at greater risk for SDS when planted into cool, wet soils, when soybean cyst nematode (SCN) is present, and when summer rains cause saturated soils.  Managing SDS can involve several practices such as relieving soil compaction, delaying planting, and selecting soybean products with a good disease tolerance package.

TL;DR: In this article, a model of symbolic consumption activities and psychological phenomena that occur during major life transitions is developed, and consumers in transition appear to rely on possessions that symbolize the past, as well as those that represent the new role, to help facilitate a major life transition.
Abstract: Integrating Belk's (1988) notion of the “extended self” with van Gennep's (1960) framework of “liminal transitions,” a model of symbolic consumption activities and psychological phenomena that occur during major life transitions is developed. In an initial investigation, the transition from high school to college is used to explore the nature of the liminal experience, the role that symbolic consumption assumes in the process, and the effects of both on consumers' psychological states. The results suggest that certain negative psychological consequences are indicative of existence in a liminal state. Further, consumers in transition appear to rely on possessions that symbolize the past, as well as those that represent the new role, to help facilitate a major life transition. Directions for future research are offered. © 1997 John Wiley & Sons, Inc.

TL;DR: Results indicated that field-collected colonies of H. virescens, H. zea, P. includens, and S. frugiperda were as susceptible as laboratory-reared colonies and those reported in the literature to the purified endotoxin proteins Cry1Ac and Cry1Ab.
Abstract: Susceptibility of Heliothis virescens (F.), Helicoverpa zea (Boddie), Pseudoplusia includens (Walker), Spodoptera exigua (Hubner), and Spodoptera frugiperda (J. E. Smith) to purified endotoxins and commercial formulations of Bacillus thuringiensis Berliner was measured in a wide range of colonies collected from 8 states in the U.S. Cotton Belt during 1992 and 1993. Results indicated that field-collected colonies of H. virescens, H. zea, P. includens, and S. frugiperda were as susceptible as laboratory-reared colonies and those reported in the literature to the purified endotoxin proteins Cry1Ac and Cry1Ab or the commercial formulations Javelin WG, Dipel ES, and Condor OF in diet-treated assays. Colonies of S. exigua collected from transgenic cotton expressing endotoxin protein had elevated median lethal concentrations (LC50s) compared with a colony collected from nontransgenic cotton or those from laboratory colonies. Ranges of LC50s for field-collected colonies of H. virescens generally were similar to the ranges observed for laboratory colonies and similar to those reported in the literature. Wider ranges of variation in LC50s were observed among populations of H. zea and S. exigua than among populations of the other species. However, the highest LC50 observed for H. zea was no higher than those reported in the literature. Only a few colonies of P. includens and S. exigua were tested. P. includens susceptibility was generally greater than that of H. virescens and less than that of H. zea. S. frugiperda was the least susceptible species studied. Variability in LC50s obtained with Cry1Ac ( r = 0.702) correlated with variability in LC50s for Cry1Ab across 13 colonies of H. virescens exposed to both proteins. Colonies of H. zea and H. virescens were pooled into single colonies and selected with the insecticidal proteins to produce endotoxin-resistant strains. Selection for resistance in H. virescens was not successful, but a strain of H. zea was selected that had elevated LC50s (10 times) after 2 generations and very high LC50s compared with a susceptible laboratory strain (100 times) after 8 generations, suggesting that H. zea has the genetic capacity to develop resistance to endotoxin proteins.

TL;DR: The hypothesis that redox disturbances contribute to immobilization-induced skeletal muscle atrophy and that mitochondria are an important source of ROS production in muscle fibers during prolonged periods of inactivity are supported.
Abstract: Prolonged periods of muscular inactivity (e.g., limb immobilization) result in skeletal muscle atrophy. Although it is established that reactive oxygen species (ROS) play a role in inactivity-induced skeletal muscle atrophy, the cellular pathway(s) responsible for inactivity-induced ROS production remain(s) unclear. To investigate this important issue, we tested the hypothesis that elevated mitochondrial ROS production contributes to immobilization-induced increases in oxidative stress, protease activation, and myofiber atrophy in skeletal muscle. Cause-and-effect was determined by administration of a novel mitochondrial-targeted antioxidant (SS-31) to prevent immobilization-induced mitochondrial ROS production in skeletal muscle fibers. Compared with ambulatory controls, 14 days of muscle immobilization resulted in significant muscle atrophy, along with increased mitochondrial ROS production, muscle oxidative damage, and protease activation. Importantly, treatment with a mitochondrial-targeted antioxidant attenuated the inactivity-induced increase in mitochondrial ROS production and prevented oxidative stress, protease activation, and myofiber atrophy. These results support the hypothesis that redox disturbances contribute to immobilization-induced skeletal muscle atrophy and that mitochondria are an important source of ROS production in muscle fibers during prolonged periods of inactivity.

TL;DR: In this article, an unbalanced three-phase load flow algorithm that can handle multiple sources is described, which is capable of switching the DG mode of operation from constant voltage to constant power factor.
Abstract: With the increased installations of distributed generators (DGs) within power systems, load flow analysis of distribution systems needs special models and algorithms to handle multiple sources. In this paper, the development of an unbalanced three-phase load flow algorithm that can handle multiple sources is described. This software is capable of switching the DG mode of operation from constant voltage to constant power factor. The algorithm to achieve this in the presence of multiple DGs is proposed. Shipboard power systems (SPS) have other special characteristics apart from multiple sources, which make the load flow difficult to converge. The developed software is verified for a distribution system without DG using the Radial Distribution Analysis Package (RDAP). The developed software analyzes an IEEE test case and an icebreaker ship system. System studies for the IEEE 37-node feeder without the regulator show the effect of different models and varying DG penetration related to the increase in loading. System losses and voltage deviations are compared.
