The Foster Parents Dilemma Who Can I Turn to When Somebody Needs Me?

One cannot help but feel compassion for foster parents who merely try to do what they feel is best for a child they love. The rights in this regard and chances of success in asserting these rights in court will be explored in this Article

Origin of the Mosaicity in Graphene Grown on Cu(111)

We use low-energy electron microscopy to investigate how graphene grows on Cu(111). Graphene islands first nucleate at substrate defects such as step bunches and impurities. A considerable fraction of these islands can be rotationally misaligned with the substrate, generating grain boundaries upon interisland impingement. New rotational boundaries are also generated as graphene grows across substrate step bunches. Thus, rougher substrates lead to higher degrees of mosaicity than do flatter substrates. Increasing the growth temperature improves crystallographic alignment. We demonstrate that graphene growth on Cu(111) is surface diffusion limited by comparing simulations of the time evolution of island shapes with experiments. Islands are dendritic with distinct lobes, but unlike the polycrystalline, four-lobed islands observed on (100)-textured Cu foils, each island can be a single crystal. Thus, epitaxial graphene on smooth, clean Cu(111) has fewer structural defects than it does on Cu(100).Comment: Article revised following reviewer comment

Real-time observation of epitaxial graphene domain reorientation.

Graphene films grown by vapour deposition tend to be polycrystalline due to the nucleation and growth of islands with different in-plane orientations. Here, using low-energy electron microscopy, we find that micron-sized graphene islands on Ir(111) rotate to a preferred orientation during thermal annealing. We observe three alignment mechanisms: the simultaneous growth of aligned domains and dissolution of rotated domains, that is, 'ripening'; domain boundary motion within islands; and continuous lattice rotation of entire domains. By measuring the relative growth velocity of domains during ripening, we estimate that the driving force for alignment is on the order of 0.1 meV per C atom and increases with rotation angle. A simple model of the orientation-dependent energy associated with the moiré corrugation of the graphene sheet due to local variations in the graphene-substrate interaction reproduces the results. This work suggests new strategies for improving the van der Waals epitaxy of 2D materials

Role of the Hospital in the 21st Century Opioid Overdose Epidemic: The Addiction Medicine Consult Service

Objective: The aim of the study was to explore and describe the structure and design elements of addiction medicine consult (AMC) services within selected US hospitals. Methods: As part of a larger mixed methods study, 10 qualitative semi-structured telephone interviews were completed with board-certified addiction medicine physicians affiliated with the Addiction Medicine Foundation\u27s Addiction Medicine Fellowship Programs at 9 US hospitals. Interviews were transcribed, coded, and analyzed using a directed content analysis. Results: Interviews completed with established AMC services in 9 hospitals probed AMC structure and design commonalities and differences across 4 domains: (1) availability and coverage, (2) team composition, (3) scope and responsibility, and (4) financing. Only 1 service provided weekend consults and most services did not provide coverage in the emergency department. Interprofessional teams were common with a variety of discipline combinations. AMC service scope and responsibility, generally, included 3 types of activities: (1) education and culture change, (2) the delivery of psychosocial and medical services, and (3) hospital guidance document development. Finally, most AMC services existed within a fragile financial environment with idiosyncratic arrangements. Conclusions: As opioid use disorder (OUD)-related hospitalizations increase stakeholders look to innovative care delivery mechanisms to improve care and outcomes for persons with OUD. The implementation of an AMC service may be an organizational intervention for achieving these aims. Understanding the shared and different approaches to AMC service structure and design is an important first step for delivery systems interested in implementing or expanding these services

Combining Barley and Oats for Growing-Finishing Gilts

Northcentral South Dakota is an area in which corn is not produced in sufficient quantity for livestock feed needs. Since barley and oats are also produced in the area, both are used singly or in combination for swine production. Work at the Northcentral Substation, Eureka, has demonstrated that properly supplemented all- barley rations support rapid growth and efficient gains for swine. Because of interest in the area in using oats also for swine rations this trial was designed to compare barley alone with combinations of barley and oats
