TL;DR: The dispersive properties of the atomic transition in the rubidium line are measured and this ladder-type system is observed to exhibit electromagnetically induced transparency together with a rapidly varying refractive index.
Abstract: The dispersive properties of the atomic transition in the rubidium ${D}_{2}$ line ($5{S}_{\frac{1}{2}}\ensuremath{-}5{P}_{\frac{3}{2}}$) at 780.0 nm are measured with a Mach-Zehnder interferometer when an additional coupling field at 775.8 nm is applied to an upper transition ($5{P}_{\frac{3}{2}}\ensuremath{-}5{D}_{\frac{5}{2}}$). This ladder-type system is observed to exhibit electromagnetically induced transparency together with a rapidly varying refractive index. A reduction in group velocity for the probe beam (${v}_{g}=\frac{c}{13.2}$) is inferred from the measured dispersion curve with 52.5% suppressed absorption on resonance.

TL;DR: The Social Psychology of Prosocial Behavior as discussed by the authors examines prosocial behavior from a multilevel perspective that explores the diverse influences that promote actions for the benefit of others and the myriad ways that prosocial actions can be manifested.
Abstract: Written by four leading researchers in the study of prosocial behavior, this book introduces a new perspective on prosocial behavior for the 21st century. Building on the bystander intervention work that has defined this area since the 1960s, The Social Psychology of Prosocial Behavior examines prosocial behavior from a multilevel perspective that explores the diverse influences that promote actions for the benefit of others and the myriad ways that prosocial actions can be manifested. The authors expand the breadth of the field, incorporating analyses of biological and genetic factors that predispose individuals to be concerned for the well being of others, as well as planned helping such as volunteering and organizational citizenship behavior and cooperative behavior within and between groups. They identify both the common and the unique processes that underlie the broad spectrum of prosocial behavior.Each chapter begins with a question about prosocial behavior and ends with a summary that answers the question. The final chapter summarizes the questions and the answers that research provides. Conceptual models that elaborate on and extend the multilevel approach to prosocial behavior are used to tie these findings together. The book concludes with suggestions for future research. The Social Psychology of Prosocial Behavior addresses the following:*the evolution of altruistic tendencies and other biological explanations of why humans are predisposed to be prosocial;*how the situation and motives that are elicited by these situations affect when and how people help;*the causes and maintenance of long-term helping, such as volunteering;*how prosocial behavior changes over time and the developmental processes responsible for these changes;*the consequences of helping for both the people who provide it and those who receive it;*helping and cooperation within and between groups and the implications of these actions.This accessible text is ideal for advanced courses on helping and altruism or prosocial behavior, taught in psychology, sociology, management, political science, and communication, or for anyone interested in learning more about prosocial behavior in general.

TL;DR: Results show that while 'health' is a major consumer motive, a broad diversity of drivers influence the clean label trend with particular relevance of intrinsic or extrinsic product characteristics and socio-cultural factors, however, 'free from' artificial additives/ingredients food products tend to differ from organic and natural products.

TL;DR: In this article, high quality InP nanocrystals without any size sorting were synthesized in a noncoordinating solvent by strictly controlling the reaction parameters, which is much faster, less expensive, and "greener" than any current methods.
Abstract: High quality InP nanocrystals without any size sorting were synthesized in a noncoordinating solvent by strictly controlling the reaction parameters. This synthetic method is much faster, less expensive, and “greener” than any current methods for the synthesis of high quality InP nanocrystals. Fatty acids with well-defined chain lengths as the ligands, a noncoordinating solvent, and a thorough degassing process are critical factors for the formation of high quality InP nanocrystals. The growth of nearly monodisperse InAs nanocrystals through a similar scheme was also observed.

TL;DR: The crop plant model rice ( Oryza sativa) is used here as an example to highlight mechanisms and genes for adaptation of crop plants to drought stress.
Abstract: Plants in their natural habitats adapt to drought stress in the environment through a variety of mechanisms, ranging from transient responses to low soil moisture to major survival mechanisms of escape by early flowering in absence of seasonal rainfall. However, crop plants selected by humans to yield products such as grain, vegetable, or fruit in favorable environments with high inputs of water and fertilizer are expected to yield an economic product in response to inputs. Crop plants selected for their economic yield need to survive drought stress through mechanisms that maintain crop yield. Studies on model plants for their survival under stress do not, therefore, always translate to yield of crop plants under stress, and different aspects of drought stress response need to be emphasized. The crop plant model rice ( Oryza sativa) is used here as an example to highlight mechanisms and genes for adaptation of crop plants to drought stress.
