Ambipolar charge injection and transport in a single pentacene monolayer island
Electrons and holes are locally injected in a single pentacene monolayer
island. The two-dimensional distribution and concentration of the injected
carriers are measured by electrical force microscopy. In crystalline monolayer
islands, both carriers are delocalized over the whole island. On disordered
monolayer, carriers stay localized at their injection point. These results
provide insight into the electronic properties, at the nanometer scale, of
organic monolayers governing performances of organic transistors and molecular
devices.Comment: To be published in Nano Letter
Understanding the nursing process
Support staff work closely with their patients
and members of the multidisciplinary team
to deliver high-quality care. Often this care
will have been planned by a nurse using ‘the
nursing process’. It is therefore important for
the support worker to understand how the
patient has been assessed and that the care
they are providing has been planned.
Within this article, the author will be
discussing the nursing process, explaining the
different stages and how these are used to deliver quality care. Relevant sections of The Code of Conduct for Healthcare Support
Workers and Adult Social Care Workers in England (Skills for Care and Skills for Health, 2013) will be highlighted. Support workers have a clear and important role in making sure the nursing
process is successful and patients receive the best quality care
Effect of colour vision status on insect prey capture efficiency of captive and wild tamarins (Saguinus spp.)
The colour vision polymorphism of most New World primates is a model system to study the function of colour vision. Theories for the evolution of primate trichromacy focus on the efficient detection and selection of ripe fruits and young leaves amongst mature leaves, when trichromats are likely to be better than dichromats. We provide data on whether colour vision status affects insect capture in primates. Trichromatic tamarins (Saguinus spp.) catch more prey than dichromats, but dichromats catch a greater proportion of camouflaged prey than trichromats. The prey caught does not differ in size between the two visual phenotypes. Thus two factors may contribute to the maintenance of genetic polymorphism of middle- to long-wavelength photopigments in Platyrrhines: the advantage in finding fruit and leaves, which supports the maintenance of the polymorphism through a heterozygote advantage, and the dichromats’ exploitation of different (e.g., camouflaged) food, which results in frequency-dependent selection on the different colour vision phenotypes

PENGADAAN SOSIALISASI DAN PRAKTEK PENGOLAHAN SAMPAH ORGANIK BIOMESIN MAGGOT DI DESA MARGA DAJAN PURI
Sampah menjadi salah satu permasalahan yang dihadapi oleh masyarakat. Pengelolaan sampah baik sampah organic maupun non organic menjadi hal yang perlu senantiasa diperhatikan. Banyaknya Ruang Terbuka Hijau di Desa Marga Dajan Puri menyebabkan banyaknya sampah yang dihasilkan adalah sampah organik berupa sisa-sisa makanan, dan juga sampah daun-daun dari pepohonan yang ada di sekitar desa. Tujuan dari diadakannya Kuliah Kerja Nyata (KKN) ini yaitu untuk menemukan solusi terkait permasalahan yang terdapat di Desa Marga Dajan Puri saat ini. Berdasarkan observasi terjadi kurangnya kemampuan masyarakat dalam mengelola limbah sampah organik yang ada. Hal itu terjadi karena kurangnya informasi dan edukasi kepada masyarakat. Dalam laporan ini akan dijabarkan mengenai bagaimana dengan adanya sosialisasi mengenai pengelolaan sampah organik menggunakan Biomesin Maggot tersebut dapat membantu masyarakat untuk lebih bijak dalam mengelola sampah organik di Desa Marga Dajan Puri. Sehingga dengan adanya upaya tersebut maka diharapkan dapat meningkatkan kesadaran masyarakat mengenai pentingnya kebersihan lingkungan, serta masyarakat dapat memahami konsep pengelolaan sampah organik yang dihasilkan. Metode yang digunakan adalah praktek langsung yang diawali dengan penyampaian informasi berupa edukasi yang disampaikan langsung oleh Narasumber. Dengan demikian, kegiatan ini akan menjadi efektif dilakukan untuk mengatasi permasalahan dalam pengelolaan sampah organik
Bond-randomness-induced Neel order in weakly coupled antiferromagnetic spin chains
Quasi-one-dimensional antiferromagnetic (AF) quantum spin systems show a wide
range of interesting phenomena such as the spin-Peierls transition and disorder
driven long range ordering. While there is no magnetic long range order in
strictly one-dimensional systems, in real systems some amount of interchain
coupling is always present and AF long range order may appear below a Neel
ordering temperature T_N. We study the effect of bond randomness on Neel
ordering in weakly coupled random AF S=1/2 chains both with and without
dimerization (or spin-Peierls order). We use the real space renormalization
group method to tackle the intrachain couplings, and a mean-field approximation
to treat the interchain coupling. We show that in the non-dimerized chain,
disorder (represented by bond randomness) enhances the Neel order parameter; in
the dimerized chain which shows no magnetic ordering in the weak interchain
coupling limit without randomness, disorder can actually lead to long range
order. Thus disorder is shown to lead to, or enhance the tendency toward long
range order, providing another example of the order-by-disorder phenomenon. We
make a qualitative comparison of our results with the observed phenomenon of
doping induced long range ordering in quasi-one-dimensional spin systems such
as CuGeO_3.Comment: 8 pages, 4 figure
COVID-19 outbreak at a reception centre for asylum seekers in Espoo, Finland
Publisher Copyright: © 2021Background shared accommodation may increase the risk of SARS-CoV-2 transmission. In April 2020, an increasing number of asylum seekers at a reception centre in Espoo, Finland presented with COVID-19 despite earlier implementation of preventive measures. We decided to screen the entire population of the centre for SARS-CoV-2. Methods we offered nasopharyngeal swab collection and SARS-CoV-2 real-time polymerase chain reaction (RT-PCR) analysis to the centre's clients. Symptoms were recorded at the time of diagnostic sample collection using electronic forms and followed up for two weeks through phone interviews and a review of medical records. Findings 260 clients were screened. Of them, 96 (37%) were found positive for SARS-CoV-2 and isolated. The high attack rate prompted the local public health authority to set the other clients in quarantine for 14 days to prevent further spread. Of the positive cases, 61 (64%) reported having had symptoms at the time of the screening or one week prior. Of the 35 initially asymptomatic individuals, 12 developed symptoms during follow-up, while 23 (or 18% of all screened SARS-CoV-2 positive clients) remained asymptomatic. No widespread transmission of COVID-19 was detected after the quarantine was lifted. Interpretation in this large COVID-19 outbreak, voluntary mass screening provided valuable information about its extent and helped guide the public health response. Comprehensive quarantine and isolation measures were likely instrumental in containing the outbreak.

Inverse Spectral-Scattering Problem with Two Sets of Discrete Spectra for the Radial Schroedinger Equation
The Schroedinger equation on the half line is considered with a real-valued,
integrable potential having a finite first moment. It is shown that the
potential and the boundary conditions are uniquely determined by the data
containing the discrete eigenvalues for a boundary condition at the origin, the
continuous part of the spectral measure for that boundary condition, and a
subset of the discrete eigenvalues for a different boundary condition. This
result extends the celebrated two-spectrum uniqueness theorem of Borg and
Marchenko to the case where there is also a continuous spectru
Weakening of Jupiter's main auroral emission during January 2014
In January 2014 Jupiter's FUV main auroral oval decreased its emitted power by 70% and shifted equatorward by ∼1°. Intense, low-latitude features were also detected. The decrease in emitted power is attributed to a decrease in auroral current density rather than electron energy. This could be caused by a decrease in the source electron density, an order of magnitude increase in the source electron thermal energy, or a combination of these. Both can be explained either by expansion of the magnetosphere or by an increase in the inward transport of hot plasma through the middle magnetosphere and its interchange with cold flux tubes moving outward. In the latter case the hot plasma could have increased the electron temperature in the source region and produced the intense, low-latitude features, while the increased cold plasma transport rate produced the shift of the main oval
