Review of Disruptive Technologies in 3D BioprintingNARA Subscribed
Purpose of Review The purpose of this review is to share insights from recognized experts in 3D biopriniting on the recent advances in these technologies discussed during a recent workshop held in conjunction with the 2024 ISS National Laboratory Research and Development Conference (ISSRDC). We seek to answer how microgravity can be used as a disruptor to make further advances not possible through conventional means. Recent Fi...
Mechanical and poroelastic behavior of porous tuff under drained and undrained conditionsNARA Subscribed
A series of drained and undrained water-saturated constant mean-stress tests were performed to investigate the strength, elasticity, and poroelastic response of a water-saturated high porosity nonwelded tuff. Drained strengths are found to increase with increasing effective confining pressures. Elastic moduli increase with increasing mean stress. Undrained strengths are small due to development of high pore pressures that gene...
The Ghareb Formation is a shallowly buried porous chalk in southern Israel that is being considered as a host rock for a geologic nuclear waste repository. Setup and operation of a repository will induce significant mechanical, hydrological and chemical perturbations in the Ghareb. Developing a secure repository requires careful characterization of the rock behavior to different loads. To characterize hydromechanical behavior...
Research priorities for measuring biologic age: summary and future directions from the Research Centers Collaborative Network WorkshopNARA Subscribed
Biologic aging reflects the genetic, molecular, and cellular changes underlying the development of morbidity and mortality with advancing chronological age. As several potential mechanisms have been identified, there is a growing interest in developing robust measures of biologic age that can better reflect the underlying biology of aging and predict age-related outcomes. To support this endeavor, the Research Centers Collabor...
The ocean provides food, economic activity, and cultural value for a large proportion of humanity. Our knowledge of marine ecosystems lags behind that of terrestrial ecosystems, limiting effective protection of marine resources. We describe the outcome of 2 workshops in 2011 and 2012 to establish a list of important questions, which, if answered, would substantially improve our ability to conserve and manage the world's marine...
Hereditary prostate cancer as a feature of Lynch SyndromeNARA Subscribed
A new species of Falcaustra (Nematoda, Kathlaniidae) from Cnemaspis aff. tro pidogaster (Squamata, Gekkonidae) from Sri LankaNARA Subscribed
Falcaustra desilvai sp. nov. (Ascaridida, Kathlaniidae) from the large intestine of Cnemaspis aff. tropidogaster (Squamata, Gekkonidae) is described and illustrated. Falcaustra desilvai represents the 4th nematode species from Sri Lanka to be assigned to the genus and is distinguished from other Sri Lankan species by the distribution pattern of caudal papillae (12 precloacal, 2 adcloacal, 10 postcloacal, and 1 median), length...
