Technical report on the environmental monitoring of the cage area at the Source of the Nile (SON) Fish Farm for quarter 1: January-March 2011

The first environmental survey was undertaken in February 2011. The survey covered physical-chemical parameters (Water depth, water transparency, water column temperature, dissolved oxygen, pH and conductivity), nutrient status, algal and invertebrate communities (algae, micro-invertebrates/zooplankton and macro-invertebrates/macro-benthos) and the fish community. This report presents the field observations made and provides a scientific interpretation and discussion of the results with reference to possible impacts of the cage facilities to the water environment and the different aquatic biota at and around the cage site including natural fish communities.

Technical report on the environmental monitoring of the cage area at the Source of the Nile (SON) Fish Farm for quarter 1: January-March 2015

Source of the Nile (SON) fish farm is located at Bugungu in Napoleon Gulf, northern Lake Victoria. The proprietors of the farm have a collaborative arrangement with NaFIRRI, a lead agency in fisheries research and innovations, to undertake quarterly environment monitoring surveys at the farm. The agreed areas for monitoring are: selected physico-chemical parameters (i.e. temperature, dissolved oxygen, pH, conductivity, secchi depth); total suspended solids (TSS); nutrient status; BOD5) and biological parameters (i.e. algae, zooplankton, macro-benthos and fish). Water and biological samples as well as field measurements were taken at 3 sites: within the fish cage rows (WIC/experimental), upstream (USC/control) and downstream (DSC) of the fish cages. The key research question was: Does fish cage operations have impacts on the water quality and aquatic biota in and around the SON cage fish farm? The environment monitoring surveys were projected to cover a full calendar year (i.e. from January to December). The first surveys were undertaken in 2011 and have continued on an annual basis since then. The present report presents field observations made for the fourth quarter survey undertaken in November 2014 and provides a scientific interpretation and discussion of the results with reference to possible impacts of the cage facilities to the water environment and the different aquatic biota in and around the fish cage site.

Sireenit, floksit ja iirikset- Puu-Käpylän koristekasvit

Puu-Käpylä (“Wooden Käpylä”), a neighbourhood of Helsinki, is the earliest example of the Garden City Movement in Finland. The suburb of valuable wooden architecture was built between 1920 and 1925, with the aim to provide a healthy housing area for working-class families with many children. The houses were erected by a co-operative (Käpylän kansanasunnot, “People?s Dwellings”) and they are protected by the city plan since 1960?s. However, the historical value of the sheltered courtyards has not been investigated. The aim of this study was to survey the garden flora of Puu-Käpylä and to evaluate the authenticity of the courtyard gardens. The survey covered the area of one residential quarter (1.2 ha) with twelve 2-storey semi-detached timber houses arranged around a common yard, which was originally appointed for the tenants? vegetable gardens. The houses are still rented, and each flat is allowed a small lot of the courtyard for cultivation. A complete list was made of all perennial, ornamental plant taxa present in the quarter. Spring bulbs were missed due to the timing of the survey. Generally, the plants were recorded on species level, with the exception of common lilacs, shrub roses, irises and peonies that were thoroughly studied for cultivar identification. It was assumed that plants initially grown in the courtyard could be distinguished by studying Finnish garden magazines, books and nursery catalogues published in the 1920?s and by comparing the present vegetation to surviving documents from the quarter. The total number of ornamental plant taxa identified was 172, of which 17 were trees, 47 shrubs, 7 climbers and 101 herbaceous perennials. The results indicated that a major part of the shrubs, climbers and perennials presumably originated from the 1970?s or later, whereas ca. 70 % of the tree specimens were deemed as original. The survey disclosed a heritage variety of common lilac, resembling cultivar „Prince Notger?, a specific peony taxon, Paeonia humilis Retz., cultivated in Nordic countries since long ago, and a few historic iris varieties. Well-preserved design elements included front gardens on one side of the quarter, a maple alley on another side as well as trees at the garden gates. Old garden books and magazines did not shed much light on the Finnish garden flora commonly used in the period when Puu-Käpylä was built. However, they gave a valuable picture of contemporary planting design. Nursery catalogues offered insight into the assortment of ornamental plants traded in the 1920?s. Conclusions on the authenticity of the current flora were mainly drawn on the basis of old photographs and a vegetation survey map drawn in the 1970?s. This study revealed a need for standardization of syrvey methods applied when investigating garden floras. Uniform survey techniques would make the results comparable and enable a future compilation of data from e.g. historic gardens.

A Bayesian method for detecting stellar flares

We present a Bayesian-odds-ratio-based algorithm for detecting stellar flares in light-curve data. We assume flares are described by a model in which there is a rapid rise with a half-Gaussian profile, followed by an exponential decay. Our signal model also contains a polynomial background model required to fit underlying light-curve variations in the data, which could otherwise partially mimic a flare. We characterize the false alarm probability and efficiency of this method under the assumption that any unmodelled noise in the data is Gaussian, and compare it with a simpler thresholding method based on that used in Walkowicz et al. We find our method has a significant increase in detection efficiency for low signal-to-noise ratio (S/N) flares. For a conservative false alarm probability our method can detect 95 per cent of flares with S/N less than 20, as compared to S/N of 25 for the simpler method. We also test how well the assumption of Gaussian noise holds by applying the method to a selection of 'quiet' Kepler stars. As an example we have applied our method to a selection of stars in Kepler Quarter 1 data. The method finds 687 flaring stars with a total of 1873 flares after vetos have been applied. For these flares we have made preliminary characterizations of their durations and and S/N.

Studies of the structure and function of a fibrinogen binding MSCRAMM(RTM) from Staphylococcus epidermidis

Coagulase-negative staphylococci (CNS) are recognized as important pathogens and are particularly associated with foreign body infections. S. epidermidis accounts for approximately 75% of the infections caused by CNS. Three genes, sdrF, sdrG, and sdrH, were identified by screening a S. epidermidis genomic library with a probe encompassing the serine-aspartate dipeptide repeat-encoding region (region R) of clfA from S. aureus. SdrG has significant amino acid identity to ClfA, ClfB and other surface proteins of S. aureus. SdrG is also similar to a protein (Fbe) recently described by Nilsson, et al. (Infection and Immunity, 1998, 66:2666–73) from S. epidermidis. The N-terminal domain (A region) of SdrG was expressed as a his-tag fusion protein in E. coli. In an ELISA, this protein, rSdrG(50-597) was shown to bind specifically to fibrinogen (Fg). Western ligand blot analysis showed that SdrG binds the Bβ chain of Fg. To further characterize the rSdrG(50-597)-Fg interaction, truncates of the Fg Bβ chain were made and expressed as recombinant proteins in E. coli. SdrG was shown to bind the full-length Bβ chain (1462), as well as the N-terminal three-quarters (1-341), the N-terminal one-half (1-220) and the N-terminal one-quarter (1-95) Bβ chain constructs. rSdrG(50-597) failed to bind to the recombinant truncates that lacked the N-terminal 25 amino acid residues of this polypeptide suggesting that SdrG recognizes a site within this region of the Bβ chain. Inhibition ELISAs have shown that peptide mimetics, including β1–25, and β6–20, encompassing this 25 residue region can inhibit binding of rSdrG(50-597) to Fg coated wells. Using fluorescence polarization we were able to determine an equilibrium constant (KD) for the interaction of rSdrG(50-597) with the Fg Bβ chain peptide β1–25. The labeled peptide was shown to bind to rSdrG(50-597) with a KD of 0.14 ± 0.01μM. Because rSdrG(50-597) recognizes a site in the Fg Bβ chain close to the thrombin cleavage site, we investigated the possibility of the rSdrG(50-597) site either overlapping or lying close to this cleavage site. An ELISA showed that rSdrG(50-597) binding to thrombin-treated Fg was significantly reduced. In a clot inhibition assay rSdrG(50-597) was able to inhibit fibrin clot formation in a concentration dependent manner. Furthermore, rSdrG(50-597) was able to inhibit clot formation by preventing the release of fibrinopeptide B as determined by HPLC. To further define the interaction between rSdrG(50-597) and peptide β6–20, we utilized an alanine amino acid replacement strategy. The residues in β6–20 that appear to be important in rSdrG(50-597) binding to Fg, were confirmed by the rSdrG(273-597)-β6–20 co-crystal structure that was recently solved by our collaborators at University of Alabama-Birmingham. Additionally, rSdrG(50-597) was not able to bind to Fg from different animal species, rather it bound specifically to human Fg in an ELISA. This suggests that the sequence variation between Fg Bβ chains of different species, specifically with in the N-terminal 25 residues, affects the ability of rSdrG(50-597) binding to Fg, and this may explain why S. epidermidis is primarily a human pathogen. ^

Saving Young Lives: Pathfinder International’s Youth-Friendly Postabortion Care Project

As many as 2.5 million adolescent women seek abortion each year, and nearly 70,000 women die from complications related to unsafe abortion, of which almost half are women under the age of 25. A further 5 million women suffer disability due to unsafe abortion yearly. In most developing countries, abortion is legally restricted or highly inaccessible, which leads young women to seek services from unskilled practitioners often leading to incomplete, septic abortions and massive bleeding, which can result in permanent injury, infertility, and death. Based on our deeply held belief that all people, including adolescents, have a right to sexual and reproductive health services and the importance of addressing adolescent needs within Postabortion Care (PAC) services, Pathfinder used private funds to initiate a Youth-Friendly Postabortion Care (YFPAC) program in eight sub-Saharan African countries. Implemented between June 2007 and May 2008, the YFPAC program offered an opportunity to apply the PAC Consortium’s Technical Guidance on Youth-Friendly PAC, generating promising approaches and lessons learned. The goal of the YFPAC initiative was to increase access to PAC services that are responsive to adolescent needs in sub-Saharan Africa. While outcomes varied according to the country, the overall outcomes included: Increased community support for services and activities that prevent unwanted pregnancy, decreased stigma around abortion, and awareness of the issue of unsafe abortion among adolescent women: 311 peer educators reached almost 17,487 youth and other community members; 171 stakeholders (e.g., religious and traditional leaders, health officials, and local government officials) were sensitized on YFPAC, resulting in a positive shift in communities’ attitudes toward youth in need of PAC services. 125 service providers were trained to deliver YFPAC services and three doctors in Ghana were provided with a technical update on YFPAC. YFPAC services are available in Angola, Ghana, Nigeria, Mozambique, Tanzania, Uganda, Ethiopia, and Kenya. Pathfinder introduced YFPAC services into 25 facilities (in 27 service delivery points), and provided more than 3,800 clients with YFPAC services throughout the eight countries. The number of adolescent PAC clients seen at the project facilities increased— 710 clients were seen in the first quarter, 1,144 were seen in the fourth. The number of adolescent PAC clients who adopt a contraceptive method to prevent future unintended pregnancies has increased. Statistics show an average postabortion contraceptive acceptance of 69%, with the highest acceptance being 83% and the lowest being 44%. Evidence-based approaches, tools, and lessons learned are being disseminated and used for scale-up or replication of YFPAC interventions.
