Impact of the amount of parathyroid autotransplantation in total parathyroidectomy for secondary hyperparathyroidism: a prospective randomized trial [PDF]

Scientific Reports
This prospective randomized study evaluated the effect of the number of transplanted parathyroid fragments on parathyroid hormone (PTH) levels and clinical outcomes in total parathyroidectomy with autotransplantation for secondary hyperparathyroidism ...

Kriterijum efikasnosti i optimizacija mase fragmenta projektila parčadnog dejstva / Efficiency criterion and optimization of fragment mass in fragmentation projectiles [PDF]

Vojnotehnički Glasnik, 2003
U radu se razmatra problem optimizacije mase parčadi koja nastaju fragmentacijom projektila parčadnog dejstva. Pokazano je da optimalna masa parčeta prvenstveno zavisi od njegovih kinetičkih karakteristika na cilju kao i od usvojenog kriterijuma ...

Modelling the effect of habitat fragmentation on range expansion in a butterfly [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2009
There is an increasing need for conservation programmes to make quantitative predictions of biodiversity responses to changed environments. Such predictions will be particularly important to promote species recovery in fragmented landscapes, and to understand and facilitate distribution responses to climate change.

Impact of Soil on the Penetration of Prefabricated Spherical Fragments and Its Protective Effect

Applied Sciences, 2023
As a natural environmental medium, soil has a wide range of sources and is often used as a material for building houses. It can also be used to construct simple protective structures in actual battlefield environments.

Genetic diversity in butterflies: interactive effects of habitat fragmentation and climate-driven range expansion [PDF]

Biology Letters, 2005
Some species are expanding their ranges polewards during current climate warming. However, anthropogenic fragmentation of suitable habitat is affecting expansion rates and here we investigate interactions between range expansion, habitat fragmentation and genetic diversity.

Potential changes in the distributions of Near Eastern fire salamander (Salamandra infraimmaculata) in response to historical, recent and future climate change in the Near and Middle East: Implication for conservation and management

Global Ecology and Conservation, 2021
Climate change has a significant impact on the distribution of species over time. In response, species may shift, contract, extend or fragment their distributions to track preferred environmental conditions. This study aims to track the recent (1970–2000)

Fragmentation effects on an endangered species across a gradient from the interior to edge of its range

Conservation Biology, 2023
Abstract Understanding how habitat fragmentation affects individual species is complicated by challenges associated with quantifying species‐specific habitat and spatial variability in fragmentation effects within a species’ range.
