Forging volumetric methods

open access: yesArea, Volume 53, Issue 3, Page 492-500, September 2021., 2021
The last two decades have seen a “volumetric turn” within Anglophone social sciences and humanities scholarship. This turn is premised on the idea that space may be better understood in three‐dimensional terms – with complex heights and depths – rather than as a series of two‐dimensional areas or surfaces.

The WNT/β‐catenin dependent transcription: A tissue‐specific business

open access: yesWIREs Mechanisms of Disease, Volume 13, Issue 3, May/June 2021., 2021
The Wnt/β‐catenin dependent transcription is executed via a complex network of dynamically interacting co‐factors whose reciprocal requirements and timely modes of action we do not fully understand. Abstract β‐catenin‐mediated Wnt signaling is an ancient cell‐communication pathway in which β‐catenin drives the expression of certain genes as a ...

Phytoplankton composition of sawa lake, iraq

open access: yesIRAQI JOURNAL OF AQUACULTURE, 2006
The phytoplankton composition of Sawa Lake was studied monthly for 18 months, from October 1999 to March 2001. A phytoplankton net (20 µ) was used to collect phytoplankton samples. A total of 51 algal taxa was identified belong to diatoms (Bacillariophyceae), blue greens (Cyanophyceae), green algae (Chlorophyceae) and euglenoids (Euglenophyceae ...

Dwarf Spheroidal Galaxies : Keystones of Galaxy Evolution [PDF]

open access: yes, 1994
Dwarf spheroidal galaxies are the most insignificant extragalactic stellar systems in terms of their visibility, but potentially very significant in terms of their role in the formation and evolution of much more luminous galaxies. We discuss the present

The Cosmic Ray - X-ray Connection: Effects of Nonlinear Shock Acceleration on Photon Production in SNRs [PDF]

open access: yes, 2000
Cosmic-ray production in young supernova remnant (SNR) shocks is expected to be efficient and strongly nonlinear. In nonlinear, diffusive shock acceleration, compression ratios will be higher and the shocked temperature lower than test-particle, Rankine ...

Using dwarf satellite proper motions to determine their origin [PDF]

open access: yes, 2011
The highly organised distribution of satellite galaxies surrounding the Milky Way is a serious challenge to the concordance cosmological model. Perhaps the only remaining solution, in this framework, is that the dwarf satellite galaxies fall into the ...

Farmers\u27 Perception on the Performance of Different Rice Varieties in Kapilvastu District, Nepal [PDF]

open access: yes, 2020
Rice is the major staple food crop in Nepal. To date, several rice varieties have been developed and released in Nepal. However, rice production is far below in comparison with its production potential.

Detection of persistent Plasmodium spp. infections in Ugandan children after artemether-lumefantrine treatment [PDF]

open access: yes, 2014
During a longitudinal study investigating the dynamics of malaria in Ugandan lakeshore communities, a consistently high malaria prevalence was observed in young children despite regular treatment.

Improved Constraints on Northern Extratropical CO2 Fluxes Obtained by Combining Surface‐Based and Space‐Based Atmospheric CO2 Measurements

open access: yesJournal of Geophysical Research: Atmospheres, Volume 125, Issue 15, 16 August 2020., 2020
Abstract Top‐down estimates of CO2 fluxes are typically constrained by either surface‐based or space‐based CO2 observations. Both of these measurement types have spatial and temporal gaps in observational coverage that can lead to differences in inferred fluxes.
