Living by the lake: Plant food diversity in a prehistoric lake‐dwelling community in the Republic of North Macedonia

open access: yesArchaeometry, EarlyView.
Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...

Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.

Recent Advances in Cryogenic Pulsating Heat Pipes

open access: yes, 2017
Research activities regarding cryogenic pulsating heat pipes (PHPs) are quickly springing up around the world. The strong interest is motivated in part by the exciting potential of PHPs for many cryogenic applications where effective heat transfer over large distances is required.

Thermal Switch Characteristics of a Multi-channel Parallel Pulsating Heat Pipe

open access: yesZhileng xuebao
An experimental platform was built to evaluate the thermal switching performance of a parallel pulsating multi-channel heat pipe using fluoroether HFE-7100 as the working fluid with a liquid filling ratio of 80%.

Collagen organisation in the fibrous joint capsules in the digits of the human hand

open access: yesJournal of Anatomy, EarlyView.
The function of the finger joints is important for daily life. In this review of the literature, we consider the role of collagen and its organization within the fibrous finger joint capsules of the interphalangeal (IP) joints and investigate the relationships between collagen orientation and joint function. Abstract Normal function of the hand and, in

Low-dimensional modelling of flame dynamics in heated microchannels

open access: yes, 2014
This paper presents simulations of stoichiometric methane/air premixed flames into a microchannel at atmospheric pressure. These simulations result from numerical resolutions of reduced-order models. Indeed, combustion control into microchannels would be

Extracting vitalities: Cuts in Indigenous women's bodies‐territories (Brazil)

open access: yesMedical Anthropology Quarterly, EarlyView.
Abstract In this article, I explore the connections between the medicalization of childbirth and environmental devastation through Guarani‐Mbyá understandings of life and the living. I argue that the cuts made to Guarani‐Mbyá women's vaginas (episiotomies) in Brazilian hospitals are experienced and situated on the same cosmopolitical level as the cuts ...

Saturated flow boiling in small- to micro- diameter metallic tubes: Experimental results and modeling [PDF]

open access: yes, 2008
Some results of a long-term study of flow boiling patterns, heat transfer rates and pressure drop of R134a at pressures of 6-14 bar in five vertical stainless steel tubes of internal diameter 4.26, 2.88, 2.01, 1.1 and 0.52 mm are presented in this paper.
