Psyllid species (Cacopsylla spp.) in pear orchards of East Sarajevo [PDF]

open access: yesAgroznanje, 2016
Psyllid species (Cacopsylla spp.) are the most important pests on pear in all regions where this fruit species is grown. Cacopsylla spp. cause direct and indirect damages because they suck the sap and make large amounts of honeydew, which disturbs the ...

Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials

open access: yesAdvanced Materials, EarlyView.
Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

Highly‐Emissive Organic Photovoltaics Approaching Theoretical Limit Voltage and Enabling Multifunctional Energy‐Harvesting Displays

open access: yesAdvanced Materials, EarlyView.
A highly‐emissive organic photovoltaic employs donor–acceptor pairs with alternately localized frontier molecular orbitals, preserving high triplet energies and small reorganization energies to suppress non‐radiative recombination. As a result, it exhibits a high open‐circuit voltage approaching the Shockley–Queisser limit and a high ...

A study of population growth of Sitophilus oryzae L. and Sitophilus granarius L. in single and mixed culture in wheat and rice : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Science at Massey University [PDF]

open access: yes, 1983
Biological interactions between organisms which contend for the same resource, have been of interest to ecologists since the days of Darwin. Although this sort of association is evident for many animal-versus-animal and plant-versus-plant situations, one
