Droplets produced by continuous-ink-jet printing are widely used in various fields. The gas pressure in the feedstock tank and the perturbation imposed on a capillary jet are the primary parameters to control the formation process of the droplets. However, the lack of a simple method for producing perturbation is a major limitation of continuous-ink-jet technology. Therefore, based on the technology of electromagnetic force perturbation, a novel and simple system to produce the desired perturbation frequency is constructed in this article. Experiments were conducted with distilled water. The droplet formation process experiences three modes with the increase of the disturbance frequency. The uniform droplets could be produced in a certain region when the gas pressure in the feedstock tank is constant, and the variation of the jet tip had an important influence on the uniform droplet formation. The size of droplets could be changed by the control of the disturbance frequency.

Purpose: This study explored the narrative coherence of the accounts of an experienced event produced by autistic and neurotypical children (ages 6-15 years) after delays of two weeks and two months.
Methods: The sample comprised 27 autistic children and 32 neurotypical peers, who were interviewed about the event using the Revised National Institute of Child Health and Human Development (NICHD) Investigative Interview Protocol. The study focused on assessing the narrative coherence of children's reports, emphasizing key story grammar elements and temporal features in their narratives.

Rationale α-ET (α-ethyltryptamine), a homolog of the classical hallucinogen α-methyltryptamine, was once prescribed clinically as an antidepressant. Classical psychedelic drugs are currently of interest as potential pharmacotherapy for psychiatric disorders. Objectives Drug discrimination was used to (a) determine if α-ET-like stimulus effects could be engendered by the prototypical phenylalkylamines MDMA ("Ecstasy") or MDA ("Love Drug") and (b) evaluate the α-ET-like stimulus effects of four synthesized aryl-substituted monomethoxy analogs of α-ET (4-OMe-, 5-OMe-, 6-OMe- and 7-OMe-α-ET).

<b>Background and Objective:</b> Betta fish is one of the most popular ornamental fish because of their attractive body shape, especially for males. The fish development usually results in a similar number of males and females or an even higher number of females. This study aimed to determine the effect of various concentrations of honey and the age of larvae on the sex ratio of Betta fish.

Purpose: The Environmental influences on Child Health Outcomes (ECHO) Cohort has enrolled over 60,000 children to examine how early environmental factors (broadly defined) are associated with key child health outcomes. The ECHO Cohort may be well-positioned to contribute to our understanding of rural environments and contexts, which has implications for rural health disparities research. The present study examined the outcome of child obesity to not only illustrate the suitability of ECHO Cohort data for these purposes but also determine how various definitions of rural and urban populations impact the presentation of findings and their interpretation.
