Land Use Land Cover Change within Kakum Conservation Area in the Assin South District of Ghana, 1991-2015

Kakum Conservation Area is roughly 1187km2, extending over large portions of forest reserves in the Assin South District of Ghana. The district hosts the remaining biodiversity hotspots within highly fragmented rainforest of West Africa. Although the conservation has been gazetted as protected area, it has since been impacted by illegal chainsaw logging, expanding agricultural land use and built construction to meet the housing needs of the rapidly growing population of the district. However, there is paucity of data on the magnitude, rate and types of land cover change occurring in the district. This study seeks to address these by examining the magnitude, the rate and direction of change in land cover between 1991 and 2015. The study objective was achieved using supervised classification and post classification change detection of remotely sensed Landsat satellite imagery of the district taken in 1991, 2001 and 2015. The results show that, within the study period, the population of the area increased by 2.9%, thick forest decreased by 8.2km2, light forest increased by 5.3km2 and built environment increased by 2.9km2 per annum. These results are considered potential hindrance to sustainable development, including biodiversity conservation in the forest reserves and climate change mitigation in general. There is therefore need for measures to end deforestation and stimulate reforestation of the lost forest cover. The district needs to initiate an enquiry into the effectiveness of the current forest reserve management practices and sustainability of land use systems in the district

Improving Fall Prevention Strategies in an Acute-Care Setting

Falls with or without injuries among the elderly have become a public health concern, with falls among adults age 65 years and older increasing every year. Nurses play a role in ensuring patient safety by following fall prevention guidelines. The purpose of this evidence-based study was to implement the RE-AIM evaluation tool to determine the impact of the Safe Five program on staff compliance with the program; patients\u27 awareness of the need for falls prevention; and falls among older adults, ages 65 years and older, admitted to an acute care nursing unit. The literature supports implementing a falls prevention program with multifactorial and interdisciplinary components, and an evaluation plan to help decrease falls in acute care settings. The Safe Five falls prevention program was implemented on the acute care nursing unit in an effort to decrease the inpatient falls rate on the unit. The inpatient falls data were collected retrospectively, 2 years pre implementation of the Safe Five program, and 8 to 10 months post implementation. Data were collected from the Safe Five checklists, recorded inpatient fall rates, and high fall risk chart audits provided by staff and nurse manager; they were then analyzed using the RE-AIM evaluation tool. The long-term effects of the Safe Five program include an 18% increase in patients\u27 awareness of the importance of preventing falls, an 18% increase in staff compliance with the program, and a 14% decrease in inpatient fall rate on the unit. It is projected that the decrease in inpatient falls will result in decreased healthcare costs and improved patient satisfaction with the healthcare system, communication among the interdisciplinary team, and health outcomes for the patients

Electronic inhomogeneity and Ag:Sb imbalance of Ag1−yPb18Sb1+zTe20 high-performance thermoelectrics elucidated by 125Te and 207Pb NMR

Using magic-angle spinning 125Te and 207Pb NMR, we have discovered the presence of two phases of approximately tenfold different free-electron concentration, n, in high-performance thermoelectrics Ag1−yPb18Sb1+zTe20 (“LAST-18”), proven by pairs of Knight-shifted NMR peaks and biexponential spin-lattice relaxation. The ratio of the phases is typically 2:1 with n ≈ 2 × 1019 cm−3 and 0.2 × 1019 cm−3, respectively, determined from the spin-lattice relaxation times. 125Te NMR spectra show that both phases contain similar concentrations of Sb. The low-n component is assigned to Ag-rich regions with Ag-Sb pairing (but not AgSbTe2), the dominant high-n component to PbTe:Sb resulting from the excess of Sb relative to Ag. The electronic inhomogeneity observed here must be considered in the search for a better understanding of high performance thermoelectric materials

Project 8 Phase III Design Concept

We present a working concept for Phase III of the Project 8 experiment, aiming to achieve a neutrino mass sensitivity of $2~\mathrm{eV}$ ($90~\%$ C.L.) using a large volume of molecular tritium and a phased antenna array. The detection system is discussed in detail.Comment: 3 pages, 3 figures, Proceedings of Neutrino 2016, XXVII International Conference on Neutrino Physics and Astrophysics, 4-9 July 2016, London, U

Results from the Project 8 phase-1 cyclotron radiation emission spectroscopy detector

The Project 8 collaboration seeks to measure the absolute neutrino mass scale by means of precision spectroscopy of the beta decay of tritium. Our technique, cyclotron radiation emission spectroscopy, measures the frequency of the radiation emitted by electrons produced by decays in an ambient magnetic field. Because the cyclotron frequency is inversely proportional to the electron's Lorentz factor, this is also a measurement of the electron's energy. In order to demonstrate the viability of this technique, we have assembled and successfully operated a prototype system, which uses a rectangular waveguide to collect the cyclotron radiation from internal conversion electrons emitted from a gaseous $^{83m}$Kr source. Here we present the main design aspects of the first phase prototype, which was operated during parts of 2014 and 2015. We will also discuss the procedures used to analyze these data, along with the features which have been observed and the performance achieved to date.Comment: 3 pages; 2 figures; Proceedings of Neutrino 2016, XXVII International Conference on Neutrino Physics and Astrophysics, 4-9 July 2016, London, U
