The effect of thinning on growth and wood production of Caucasian alder (Alnus subcordata) plantation in Nowshahr region [PDF]
مجله جنگل ایران, 2009 In order to study the effect of thinning operation on growth and wood production, an alder plantation (Alnus subcordata) on deep and moist soil with medium fertility was selected and thinned during 10 years. All standing and fallen trees were measured in

Growth allocation and stand structure in Norway spruce stands [PDF]
, 2005 This thesis is based on analyses of permanent sample plot data gathered over periods of 10-34 years from an experiment in which a wide range of thinning regimes, and thinnings combined with N-fertilisation, were applied to 25 even-aged Norway spruce ...

About Thinning Invariant Partition Structures
, 2012 Bernoulli-$p$ thinning has been well-studied for point processes. Here we consider three other cases: (1) sequences $(X_1,X_2,...)$; (2) gaps of such sequences $(X_{n+1}-X_1)_{n\in\mathbb{N}}$; (3) partition structures. For the first case we characterize

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae
FEBS Open Bio, EarlyView.Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Undulatory swimming in shear-thinning fluids: Experiments with C. elegans [PDF]
, 2014 The swimming behaviour of microorganisms can be strongly influenced by the rheology of their fluid environment. In this manuscript, we experimentally investigate the effects of shear-thinning viscosity on the swimming behaviour of an undulatory swimmer ...
