Spermatogenesis in haploid males of the jewel wasp Nasonia vitripennis

open access: yesScientific Reports, 2019
Males of hymenopteran insects, which include ants, bees and wasps, develop as haploids from unfertilized eggs. In order to accommodate their lack of homologous chromosome pairs, some hymenopterans such as the honeybee have been shown to produce haploid ...

From Archives to Action: Zines, Participatory Culture, and Community Engagement in Asian America

open access: yesRadical Teacher, 2016
As a pedagogical tool, zines exist at the intersection of radical history, analog creativity, participatory culture, and community engagement. This article highlights the importance of contextualizing zines within a history of social activism to shift ...

Crossover Scales at the Critical Points of Fluids with Electrostatic Interactions

open access: yes, 1999
Criticality in a fluid of dielectric constant D that exhibits Ising-type behavior is studied as additional electrostatic (i.e., ionic) interactions are turned on.

Remembering Melodies from Another Culture: Turkish and American Listeners Demonstrate Implicit Knowledge of Musical Scales [PDF]

open access: yesAnalytical Approaches to World Music, 2019
Beyond the major-minor tonality that characterizes classical and contemporary Western musical genres, Turkish classical and folk music offer experimental psychologists a rich modal system in which cognition, development, and enculturation can be studied.

Review of novel energetic polymers and binders – high energy propellant ingredients for the new space race

open access: yesDesigned Monomers and Polymers, 2019
Current solid rocket propellant formulations still employ traditional ingredients utilized since the 1960s, such as hydroxyl terminated polybutadiene (HTPB).

Crystal structure and solution thermodynamics of the lactate complex Zn[(C3H5O3)2(H2O)2]⋅H2O(s)

open access: yesChemical Thermodynamics and Thermal Analysis, 2022
An important trihydrated lactate complex Zn[(C3H5O3)2(H2O)2]⋅H2O(s) was synthesized. Crystal structure was characterized by X-ray single crystal diffractometer, and molecular structure, spatial structure and coordination mode of the complex were ...

Highly Efficient Extraction of 212 Pb/212Bi from the Decay Chain of 232Th‐Based on Anion Exchange in Bromide Medium

open access: yesAdvanced Science, EarlyView.
This work provides an effective strategy for selectively extracting 212Pb and 212Bi from the decay chain of 232Th as well as its mechanism illustration. Using the novel strategy, 2.07 MBq of 212Pb is successfully separated from 232Th and its daughters, which enables the supply of 212Pb/212Bi directly from the abundant natural thorium resource to be ...

Accurate Prediction of Core Properties for Chiral Molecules using Pseudo Potentials [PDF]

open access: yes, 2018
Pseudo potentials (PPs) constitute perhaps the most common way to treat relativity, often in a formally non-relativistic framework, and reduce the electronic structure to the chemically relevant part.

Solid–liquid equilibria in the LiOH–ethanol–water system: Solubility measurements and thermodynamic modeling

open access: yesAIChE Journal, EarlyView.
Abstract The demand for LiOH is driven by the growth of the electric vehicle industry. Evaporative crystallization of LiOH·H2O is energy intensive, whereas ethanol‐based antisolvent crystallization has emerged as a more sustainable alternative. From a process design perspective, the crystallization yield depends on the ethanol dosage, and thermodynamic
