In this paper, an armored-cable-based optical fiber Bragg grating (FBG) sensor array, for perimeter fence intrusion detection, is demonstrated and some of the field trial results are reported. The field trial was conducted at a critical local installation in Singapore in December 2010. The sensor array was put through a series of both simulated and live intrusion scenarios to test the stability and suitability of operation in the local environmental conditions and to determine its capabilities in detecting and reporting these intrusions accurately to the control station. Such a sensor array can provide perimeter intrusion detection with fine granularity and preset pin-pointing accuracy. The various types of intrusions included aided or unaided climbs, tampering and cutting of the fence, etc. The unique sensor packaging structure provides high sensitivity, crush resistance and protection against rodents. It is also capable of resolving nuisance events such as rain, birds sitting on the fence or seismic vibrations. These sensors are extremely sensitive with a response time of a few seconds. They can be customized for a desired spatial resolution and pre-determined sensitivity. Furthermore, it is easy to cascade a series of such sensors to monitor and detect intrusion events over a long stretch of fence line. Such sensors can be applied to real-time intrusion detection for perimeter security, pipeline security and communications link security.

Full Text Available Erosion and sediment controls on construction sites minimize environmental impacts from sediment-laden stormwater runoff. Silt fence, a widely specified perimeter control practice on construction projects used to retain sediment on-site, has limited performance-based testing data. Silt fence failures and resultant sediment losses are often the result of structural failure. To better understand silt fence performance, researchers at the Auburn University-Erosion and Sediment Control Testing Facility (AU-ESCTF have evaluated three silt fence options to determine possible shortcomings using standardized full-scale testing methods. These methods subject silt fence practices to simulated, in-field conditions typically experienced on-site without the variability of field testing or the limited application of small-scale testing. Three different silt fence practices were tested to evaluate performance, which included: (1 Alabama Department of Transportation (ALDOT Trenched Silt Fence, (2 ALDOT Sliced Silt Fence, and (3 Alabama Soil and Water Conservation Committee (AL-SWCC Trenched Silt Fence. This study indicates that the structural performance of a silt fence perimeter control is the most important performance factor in retaining sediment. The sediment retention performance of these silt fence practices was 82.7%, 66.9% and 90.5%, respectively. When exposed to large impoundment conditions, both ALDOT Trench and Sliced Silt Fence practices failed structurally, while the AL-SWCC Trenched Silt Fence did not experience structural failure.

Conservationists often advocate for landscape approaches to wildlife management while others argue for physical separation between protected species and human communities, but direct empirical comparisons of these alternatives are scarce. We relate African lion population densities and population trends to contrasting management practices across 42 sites in 11 countries. Lion populations in fenced reserves are significantly closer to their estimated carrying capacities than unfenced populations. Whereas fenced reserves can maintain lions at 80% of their potential densities on annual management budgets of $500 km(-2) , unfenced populations require budgets in excess of $2000 km(-2) to attain half their potential densities. Lions in fenced reserves are primarily limited by density dependence, but lions in unfenced reserves are highly sensitive to human population densities in surrounding communities, and unfenced populations are frequently subjected to density-independent factors. Nearly half the unfenced lion populations may decline to near extinction over the next 20-40 years. © 2013 Blackwell Publishing Ltd/CNRS.

Full Text Available Global Positioning System (GPS-based virtual fences offer the potential to improve the management of grazing animals. Prototype collar devices utilising patented virtual fencing algorithms were placed on six Angus heifers in a 6.15 hectare paddock. After a “no fence” period, sequential, shifting virtual fences restricted the animals to 40%, 60%, and 80% of the paddock area widthways and 50% lengthways across 22 days. Audio cues signaled the virtual boundary, and were paired with electrical stimuli if the animals continued forward into the boundary. Within approximately 48 h, the cattle learned the 40% fence and were henceforth restricted to the subsequent inclusion zones a minimum of 96.70% (±standard error 0.01% of the time. Over time, the animals increasingly stayed within the inclusion zones using audio cues alone, and on average, approached the new fence within 4.25 h. The animals were thus attentive to the audio cue, not the fence location. The time spent standing and lying and the number of steps were similar between inclusion zones (all p ≥ 0.42. More lying bouts occurred at the 80% and lengthways inclusion zones relative to “no fence” (p = 0.04. Further research should test different cattle groups in variable paddock settings and measure physiological welfare responses to the virtual fencing stimuli.

Fencing is a high-intensity sport involving dynamic movements such as the lunge exposing the musculoskeletal system to high impact forces, which emphasises the importance of the shock attenuating properties of footwear as a factor in the prevention of injury. The aim of this study was to investigate the magnitudes of the transient axial impact shock experienced at the tibia between traditional fencing shoes and standard athletic footwear during the impact phase of the fencing lunge. Peak tibial shock was measured in 19 male fencers in 4 different footwear conditions using an accelerometer placed on the distal aspect of the tibia. The standard footwear (11.08 g and 8.75 g for squash and running shoe, respectively) resulted in significant (p Adidas and Hi-Tec shoe, respectively). No significant differences were found between the running and squash shoes (p = 0.09) or between the fencing shoes (p = 0.48). The documented reduction in impact shock found suggests that running or squash specific footwear may reduce overuse injury occurrence, indicating that there is justification for a re-design of fencing shoes.

Increasing habitat fragmentation and human population growth in Africa has resulted in an escalation in human-elephant conflict between small-scale farmers and free-ranging African elephants (Loxodonta Africana). In 2012 Kenya Wildlife Service (KWS) implemented the national 10-year Conservation and Management Strategy for the Elephant in Kenya, which includes an action aimed at testing whether beehive fences can be used to mitigate human-elephant conflict. From 2012 to 2015, we field-tested the efficacy of beehive fences to protect 10 0.4-ha farms next to Tsavo East National Park from elephants. We hung a series of beehives every 10 m around the boundary of each farm plot. The hives were linked with strong wire. After an initial pilot test with 2 farms, the remaining 8 of 10 beehive fences also contained 2-dimensional dummy hives between real beehives to help reduce the cost of the fence. Each trial plot had a neighboring control plot of the same size within the same farm. Of the 131 beehives deployed 88% were occupied at least once during the 3.5-year trial. Two hundred and fifty-three elephants, predominantly 20-45 years old entered the community farming area, typically during the crop- ripening season. Eighty percent of the elephants that approached the trial farms were kept out of the areas protected by the beehive fences, and elephants that broke a fence were in smaller than average groups. Beehive fences not only kept large groups of elephants from invading the farmland plots but the farmers also benefited socially and financially from the sale of 228 kg of elephant-friendly honey. As news of the success of the trial spread, a further 12 farmers requested to join the project, bringing the number of beehive fence protected farms to 22 and beehives to 297. This demonstrates positive adoption of beehive fences as a community mitigation tool. Understanding the response of elephants to the beehive fences, the seasonality of crop raiding and fence breaking, and the

Transportation planners are increasingly incorporating roadway design features to mitigate impacts of highways on wildlife and to increase driver safety. We used camera and track surveys to evaluate wildlife use before and after construction of 3 wildlife underpasses and associated fencing on a new section of United States Highway 64 in Washington County, North Carolina, USA. We recorded 242 occasions of white-tailed deer (Odocoileus virginianus) use of underpass areas before highway construction began. Following completion of the highway, we collected 2,433 photographs of 9 species with deer representing 93% of all crossings. Adjusting for differences in number of monitoring days, white-tailed deer use of underpass areas averaged 6.7 times greater after the new highway and underpasses were completed. We recorded 3,614 wildlife crossings of ≥20 species based on track counts, representing most medium and large mammals known to occur in the area and several reptiles and birds. After completion of the highway, we documented wildlife mortality due to vehicle collisions during a 13-month period and recorded 128 incidences representing ≥24 species. Within fenced highway segments, mortalities were lowest near underpasses and increased with distance from the underpasses. However, we also documented more mortalities in fenced areas compared with unfenced areas. With greater distance from an underpass, animals with smaller home ranges seemed less likely to reach the underpass and instead attempted to climb over or crawl under fencing. Based on collision reports from adjacent highway sections, the new section of United States Highway 64 experienced approximately 58% fewer wildlife mortalities (primarily white-tailed deer), suggesting underpasses and fencing reduced the number of deer–vehicle collisions. Continuous fencing between underpasses may further reduce the number of vehicle collisions for deer but additional design features (e.g., buried fencing) should be

Full Text Available [Objectives] Stress concentration is prone to take place at connections between the opening fence and ring ribs of a ring-stiffened cylindrical shell under external pressure. [Methods] In this paper, a topological optimization method for the brackets that connect the fence to the ring ribs is proposed in order to effectively reduce the local high stress in the brackets. The sub-model technique is used to analyze the stress of the connecting brackets. In the design, the connection brackets are used as design variables and the stress of the shell, fence and ribs are used as constraints. The maximum stress of the bracket is minimized as the objective function. The topology optimization results are engineered to obtain the final form of the brackets. [Results] The calculation results show that brackets of which the panel is partially widened can effectively reduce the stress concentration position of the opening fence transverse offset if the side of the bracket away from the longitudinal section is longer; the opening fence is offset relative to the brackets, and the symmetrical design of the brackets is feasible. [Conclusions] This research provides a reference for similar structural design.

The installation standards for protective fence was revised last November, and public interest is increased for these standards. Corresponding to this situation, the Cement Association held a revised installation standards explanation meeting, in cooperation with Steel Protective Fence Association and Japan Aluminum Association, in Tokyo for road managers mainly in areas under jurisdiction of Kanto Regional Construction Bureau. By the revised installation standards, concrete protective fence can be treated equal to steel. Traffic safety of drivers and passengers as well as economic effect by long maintenance span can be expected by popularization of concrete protective fence. (translated by NEDO)

Full Text Available Fencing is a combat sport whose form of direct confrontation involves hitting the opponent with a weapon. The purpose of the study was to determine the properties of body composition of female representatives of the Polish national fencing team. The study involved 11 female athletes of the Polish national fencing team. Their age was 16-22 years (19±2.32, body weight 52-78 kg (59.7±7.4, body height 158-183 cm (167.46±6.10 and the training experience 7.64±3.47 years. The reference group consisted of 153 students of Warsaw University of Technology (Poland. Twenty basic somatic characteristics were measured. The following indices were calculated: slenderness, Rohrer’s, BMI, Manouvrier’s, and pelvic-shoulder indices. Density of the body, total body fat, active tissue, the overall profile of body composition and internal proportions of the body were determined. Analysis of internal proportions of factors of the athletes’ body composition revealed significant differences in particular groups of features. The total size of the athletes’ bodies is due to less-than-average magnitude of the length and stoutness characteristics and a high magnitude of adiposity (M = 0.63 in the Polish female national team of fencers (sabre calculated from the normalized values for the control group. The proportions of features within the analysed factors revealed a significant advantage of the length of the upper extremity over the lower one and a distinct advantage of forearm musculature. The specific profile of body composition of female athletes practising sabre fencing is most likely due to long-term effects of training as well as the system of selection of persons with specific somatic prerequisites developed in the course of many years of training practice.

2017-01-01

Abstract For the resection of malignant glioma, it is necessary to remove the tumor as much as possible and to avoid the expression of new neurological deficit. For this purpose, we adopted neuronavigator-guided fence-post method for malignant glioma resection in 2015. In this presentation, we will introduce this method and evaluate the usefulness of this method. Method:On one or two day before the surgery, fence-post plan is laid according to the MR images on neuronavigator system(StealthStation S7, Medtronic). Usually four fence-post are planned to involve all part of enhanced lesion of the tumor. If the tumor is located close to the pyramidal tracts, MR tractography image is also integrated in the navigator system, and fence-post are planned to avoid damaging the pyramidal tracts. During the surgery, after the craniotomy each fence-post catheter is placed according to the navigator guidance before the dural incision to avoid the influence of brain shift. After the dural incision, four planes created by adjacent each fence-post catheter are resected and the tumor is removed. Result: We will present typical three cases. Two cases of glioblastoma and one case of anaplastic oligodendroglioma case are presented. In all three cases, the tumor were located in the left frontal lobe and the tumor were gross totally removed without new neurological deficit with this method. CONCLUSION: Neuronavigator-guided fence-post method is very useful for the resection of malignant glioma.

Sinclair, J; Bottoms, L

2015-01-01

Clinical analyses have shown that injuries and pain linked specifically to fencing training/competition were prevalent in 92.8% of fencers. Patellofemoral pain is the most common chronic injury in athletic populations and females are considered to be more susceptible to this pathology. This study aimed to examine gender differences in patellofemoral contact forces during the fencing lunge. Patellofemoral contact forces were obtained from eight male and eight female club level epee fencers using an eight-camera 3D motion capture system and force platform data as they completed simulated lunges. Independent t-tests were performed on the data to determine whether gender differences in patellofemoral contact forces were present. The results show that females were associated with significantly greater patellofemoral contact force parameters in comparison with males. This suggests that female fencers may be at greater risk from patellofemoral pathology as a function of fencing training/competition.

The use of fences to segregate wildlife can change predator and prey behaviour. Predators can learn to incorporate fencing into their hunting strategies and prey can learn to avoid foraging near fences. A twelve-strand electric predator-proof fence surrounds our study site. There are also porous one-strand electric fences used to create exclosures where elephant (and giraffe) cannot enter in order to protect blocs of browse vegetation for two critically endangered species, the black rhinoceros (Diceros bicornis) and the Grevy's zebra (Equus grevyi). The denser vegetation in these exclosures attracts both browsing prey and ambush predators. In this study we examined if lion predation patterns differed near the perimeter fencing and inside the elephant exclosures by mapping the location of kills. We used a spatial analysis to compare the predation patterns near the perimeter fencing and inside the exclosures to predation in the rest of the conservancy. Predation was not over-represented near the perimeter fence but the pattern of predation near the fence suggests that fences may be a contributing factor to predation success. Overall, we found that predation was over-represented inside and within 50 m of the exclosures. However, by examining individual exclosures in greater detail using a hot spot analysis, we found that only a few exclosures contained lion predation hot spots. Although some exclosures provide good hunting grounds for lions, we concluded that exclosures did not necessarily create prey-traps per se and that managers could continue to use this type of exclusionary fencing to protect stands of dense vegetation.

The ongoing refugee crisis in Europe has seen many countries rush to construct border security fencing to divert or control the flow of people. This follows a trend of border fence construction across Eurasia during the post-9/11 era. This development has gone largely unnoticed by conservation biologists during an era in which, ironically, transboundary cooperation has emerged as a conservation paradigm. These fences represent a major threat to wildlife because they can cause mortality, obstruct access to seasonally important resources, and reduce effective population size. We summarise the extent of the issue and propose concrete mitigation measures. PMID:27331878

The Nofence technology is a GPS-based virtual fencing system designed to keep sheep within predefined borders, without using physical fences. Sheep wearing a Nofence collar receive a sound signal when crossing the virtual border and a weak electric shock if continuing to walk out from the virtual enclosure. Two experiments testing the functionality of the Nofence system and a new learning protocol is described. In Experiment 1, nine ewes with their lambs were divided into groups of three and placed in an experimental enclosure with one Nofence border. During 2 days, there was a physical fence outside the border, during Day 3 the physical fence was removed and on Day 4, the border was moved to the other end of the enclosure. The sheep received between 6 and 20 shocks with an average of 10.9±2.0 (mean±SE) per ewe during all 4 days. The number of shocks decreased from 4.38±0.63 on Day 3 (when the physical fence was removed) to 1.5±0.71 on Day 4 (when the border was moved). The ewes spent on average 3%, 6%, 46% and 9% of their time outside the border on Days 1, 2, 3 and 4, respectively. In Experiment 2, 32 ewes, with and without lambs, were divided into groups of eight and placed in an experimental enclosure. On Day 1, the enclosure was fenced with three physical fences and one virtual border, which was then increased to two virtual borders on Day 2. To continue to Day 3, when there was supposed to be three virtual borders on the enclosure, at least 50% of the ewes in a group should have received a maximum of four shocks on Day 2. None of the groups reached this learning criterion and the experiment ended after Day 2. The sheep received 4.1±0.32 shocks on Day 1 and 4.7±0.28 shocks on Day 2. In total, 71% of the ewes received the maximum number of five shocks on Day 1 and 77% on Day 2. The individual ewes spent between 0% and 69.5% of Day 1 in the exclusion zone and between 0% and 64% on Day 2. In conclusion, it is too challenging to ensure an efficient learning

Full Text Available There are a lot of obstacles type used in jumping competitions. Normally, for every kind of fence, there is a different type of approaching and cross over. The most used obstacles are the vertical fence and the oxer fence. For crossing over the vertical, which is a high fence, the horse must jump only in report to the height of the bar. In the oxer case, which is a large obstacle, the horse must jump related to the height and the largeness of it indeed. In the present study we obtained for the vertical fence, situated at five different levels. The purpose was to measure four parameters for every jump: the taking-off distance, the landing distance, and the distance between bar and legs for the front limbs and for the hind limbs. Based on these, were calculated in report to the type of the show arena the amplitude of the jumps, was assign the trajectory curve and placed the balance point.

In a move away from the open or low-fenced grounds that have traditionally been a feature of Australian school design, the last decade has seen a growth in the installation of high-security fences around schools. These structures, far from being passive and neutral, act to redefine the possibilities for movement and connectivity in the local…

[A comparative study on soil respiration between grazing and fenced typical Leymus chinensis steppe, Inner Mongolia].

With enclosed chamber Method, this paper studied the soil respiration in grazing and fenced typical Leymus chinensis steppes, Inner Mongolia, and its relationships with environmental factors. The results showed that the daily pattern of soil respiration could be expressed as a one-humped curve, and the highest values appeared at 13:00-15:00 in the fenced and grazing plots. The diurnal dynamics of soil respiration mainly depended on the surface temperature at the fenced plots and the soil temperature at 5 cm depth at the grazing plots. In June and July, the average soil respiration rate was 2.7 times greater at the fenced plots than that at the grazing plots, while the difference was not distinct in August and September, which was similar with the change of the belowground biomass. The reason was probably that the plant was influenced differently in different phenological phases by grazing and the change of environmental factors. It showed that human activity may not result in the increase of soil respiration rate. The seasonal dynamics of soil respiration was closely correlated with soil water content at the 0-10 cm depth at the fenced and grazing sites, and the maximum R2 was 0.853 and 0.741, respectively. The difference was that the correlation of soil respiration seasonal dynamics with soil water content was larger at the fenced plots than at the grazing plots. The correlations of soil respiration diurnal and seasonal dynamics with temperature and soil water content at lower profiles were larger than those at deeper profiles at the fenced and grazing sites.

Although anthropogenic pollutants are thought to threaten reptilian species, there are few toxicity studies on reptiles. We evaluated the toxicity of Pb as lead acetate to the Western fence lizard (Sceloporus occidentalis). The acute lethal dose and sub-acute (14-day) toxicity studies were used to narrow exposure concentrations for a sub-chronic (60-day) study. In the sub-chronic study, adult and juvenile male lizards were dosed via gavage with 0, 1, 10 and 20 mg Pb/kg-bw/day. Mortality was limited and occurred only at the highest dose (20 mg Pb/kg-bw/d). There were statistically significant sub-lethal effects of 10 and 20 mg Pb/kg-bw/d on body weight, cricket consumption, organ weight, hematological parameters and post-dose behaviors. Of these, Pb-induced changes in body weight are most useful for ecological risk assessment because it is linked to fitness in wild lizard populations. The Western fence lizard is a useful model for reptilian toxicity studies. - The Western fence lizard, Sceloporus occidentalis, is sensitive to Pb and is a useful laboratory model for ecotoxicological testing of reptiles.

The working fluid from the combustor to the turbine stage of a gas turbine makes various boundary layer thickness. Since the inlet boundary layer thickness is one of the important factors that affect the turbine efficiency, It is necessary to investigate secondary flow and loss with various boundary layer thickness conditions. In the present study, the effect of various inlet boundary layer thickness on secondary flow and loss and the proper height of the boundary layer fences for various boundary layer thickness were investigated. Measurements of secondary flow velocity and total pressure loss within and downstream of the passage were taken under 5 boundary layer thickness conditions, 16, 36, 52, 69, 110mm. It was found that total pressure loss and secondary flow areas were increased with increase of thickness but they were maintained almost at the same position. At the following research about the boundary layer fences, 1/6, 1/3, 1/2 of each inlet boundary layer thickness and 12mm were used as the fence heights. As a result, it was observed that the proper height of the fences was generally constant since the passage vortex remained almost at the same position. Therefore once the geometry of a cascade is decided, the location of the passage vortex and the proper fence height are appeared to be determined at the same time. When the inlet boundary layer thickness is relatively small, the loss caused by the proper fence becomes bigger than end wall loss so that it dominates secondary loss. In these cases the proper fence height is decided not by the cascade geometry but by the inlet boundary layer thickness as previous investigations

Full Text Available Purpose. The aim of the study was to compare the spatial component of proprioceptive ability by reproducing a upper limb movement typical in table tennis and fencing. Methods. The research comprised 41 young males of which 12 were table tennis players, 14 fencers, and 15 not involved in any competitive sports as a control. The experiment was based on assessing the precision of pronation and supination of the forearm at the elbow joint in recreating a set movement range by use of a goniometer. Results and conclusions. The results point to a higher level of proprioceptive ability in fencers and table tennis players than the control group but only in respect to the tasks executed with the dominant limb. This is inferred to be the result from the specific character of both sports (i.e. the intensive use of one limb and the consequent laterality of that limb causing higher sensitivity and proprioception. This may provide a link between swordplay, table tennis, and the level of proprioception. The research methodology used herein may be useful in monitoring fencing training. Although not unequivocally statistically significant, the results indicate the potential for further research in this area.

The Asotin County Conservation District (ACCD) is the primary entity coordinating habitat projects on both private and public lands within the Asotin Creek watershed. The watershed covers approximately 325 square miles in the Blue Mountains of southeastern Washington in Water Resource Inventory Area (WRIA) 35. According to Washington Department of Fish and Wildlife's (WDFW) Priority WRIA's by ''At-Risk Stock Significance Map'', it is the highest priority WRIA in southeastern Washington. Summer steelhead, bull trout, and Snake River spring chinook salmon which are listed under the Endangered Species Act (ESA), are present in the watershed. WDFW manages it as a Wild Steelhead Reserve; no hatchery fish have been released here since 1997. The ACCD has been working with landowners, Bonneville Power Administration (BPA), Washington State Conservation Commission (WCC), Natural Resource Conservation Service (NRCS), Washington Department of Fish and Wildlife (WDFW), U.S. Forest Service, Pomeroy Ranger District (USFS), Nez Perce Tribe, Washington Department of Ecology (DOE), National Marine Fisheries Service (NMFS), and U.S. Fish and Wildlife Service (USFWS) to address habitat projects in Asotin County. Local students, volunteers and Salmon Corps members from the Nez Perce Tribe have been instrumental in the success of the Model Watershed Program on Asotin Creek. ACCD began coordinating habitat projects in 1995 with the help of BPA funding. Approximately two hundred and seventy-six projects have been implemented as of 1999. The Washington State Legislature was successful in securing funding for endangered salmon and steelhead recovery throughout the State in 1998. While these issues were new to most of the State, the ACCD has been securing and administering funding for endangered salmonids since 1994. The ''Asotin Creek Riparian Planting 2000-053-00 and Asotin Creek Riparian Fencing 2000-054-00'' teamed BPA and the Governor's Salmon Recovery Funding to plant approximately 84

Yet, we know nothing about the real standard of living of these characters. The recent discovery of documents, which report the sums earned by fencing masters to teach combat disciplines, has brought us the possibility to estimate how highly this profession was regarded, and what its actual economic value was in the Italian late Middle Ages. They also give us also a material view into the modes of operation of a sala d’arme in those times.

Fenced and Fragmented: Conservation Value of Managed Metapopulations

Miller, Susan M.; Harper, Cindy K.; Bloomer, Paulette; Hofmeyr, Jennifer; Funston, Paul J.

2015-01-01

Population fragmentation is threatening biodiversity worldwide. Species that once roamed vast areas are increasingly being conserved in small, isolated areas. Modern management approaches must adapt to ensure the continued survival and conservation value of these populations. In South Africa, a managed metapopulation approach has been adopted for several large carnivore species, all protected in isolated, relatively small, reserves that are fenced. As far as possible these approaches are based on natural metapopulation structures. In this network, over the past 25 years, African lions (Panthera leo) were reintroduced into 44 fenced reserves with little attention given to maintaining genetic diversity. To examine the situation, we investigated the current genetic provenance and diversity of these lions. We found that overall genetic diversity was similar to that in a large national park, and included a mixture of four different southern African evolutionarily significant units (ESUs). This mixing of ESUs, while not ideal, provides a unique opportunity to study the impact of mixing ESUs over the long term. We propose a strategic managed metapopulation plan to ensure the maintenance of genetic diversity and improve the long-term conservation value of these lions. This managed metapopulation approach could be applied to other species under similar ecological constraints around the globe. PMID:26699333

New properties of a fiber optic sensor in application of a composite fence for critical infrastructure protection

Science.gov (United States)

Zyczkowski, M.; Szustakowski, M.; Markowski, P.

2015-09-01

This paper presents a new solution of using the composite fence with a novel fiber optic modalmetric sensor integrated within its structure. The modalmetric sensor is based on changes in a transverse modal field which is generated at the output of a multimode fiber. By a spatial limitation of the transverse modal field observation to its fragment thereof, changes' transformation in the modal distribution into changes of the output signal amplitude is made. Due to a constant analysis of the structure output signal, detection of an external disorder is possible. Integration of optical fibers with the fence structure allows for an accurate reproduction of the fence movement onto the optical fiber by significantly improving sensitivity of the modalmetric fiber sensor structure.

IB-LBM simulation on blood cell sorting with a micro-fence structure.

Wei, Qiang; Xu, Yuan-Qing; Tian, Fang-bao; Gao, Tian-xin; Tang, Xiao-ying; Zu, Wen-Hong

2014-01-01

A size-based blood cell sorting model with a micro-fence structure is proposed in the frame of immersed boundary and lattice Boltzmann method (IB-LBM). The fluid dynamics is obtained by solving the discrete lattice Boltzmann equation, and the cells motion and deformation are handled by the immersed boundary method. A micro-fence consists of two parallel slope post rows which are adopted to separate red blood cells (RBCs) from white blood cells (WBCs), in which the cells to be separated are transported one after another by the flow into the passageway between the two post rows. Effected by the cross flow, RBCs are schemed to get through the pores of the nether post row since they are smaller and more deformable compared with WBCs. WBCs are required to move along the nether post row till they get out the micro-fence. Simulation results indicate that for a fix width of pores, the slope angle of the post row plays an important role in cell sorting. The cells mixture can not be separated properly in a small slope angle, while obvious blockages by WBCs will take place to disturb the continuous cell sorting in a big slope angle. As an optimal result, an adaptive slope angle is found to sort RBCs form WBCs correctly and continuously.

The environmentally friendly synthesis of highly active Fe-N-C electrocatalysts for proton-exchange membrane fuel cells (PEMFCs) is desirable but remains challenging. A simple and scalable method is presented to fabricate Fe II -doped ZIF-8, which can be further pyrolyzed into Fe-N-C with 3 wt % of Fe exclusively in Fe-N 4 active moieties. Significantly, this Fe-N-C derived acidic PEMFC exhibits an unprecedented current density of 1.65 A cm -2 at 0.6 V and the highest power density of 1.14 W cm -2 compared with previously reported NPMCs. The excellent PEMFC performance can be attributed to the densely and atomically dispersed Fe-N 4 active moieties on the small and uniform catalyst nanoparticles. © 2018 Wiley-VCH Verlag GmbH & Co.

Using Snow Fences to Augument Fresh Water Supplies in Shallow Arctic Lakes

Energy Technology Data Exchange (ETDEWEB)

Stuefer, Svetlana

2013-03-31

This project was funded by the U.S. Department of Energy, National Energy Technology Laboratory (NETL) to address environmental research questions specifically related to Alaska's oil and gas natural resources development. The focus of this project was on the environmental issues associated with allocation of water resources for construction of ice roads and ice pads. Earlier NETL projects showed that oil and gas exploration activities in the U.S. Arctic require large amounts of water for ice road and ice pad construction. Traditionally, lakes have been the source of freshwater for this purpose. The distinctive hydrological regime of northern lakes, caused by the presence of ice cover and permafrost, exerts influence on lake water availability in winter. Lakes are covered with ice from October to June, and there is often no water recharge of lakes until snowmelt in early June. After snowmelt, water volumes in the lakes decrease throughout the summer, when water loss due to evaporation is considerably greater than water gained from rainfall. This balance switches in August, when air temperature drops, evaporation decreases, and rain (or snow) is more likely to occur. Some of the summer surface storage deficit in the active layer and surface water bodies (lakes, ponds, wetlands) is recharged during this time. However, if the surface storage deficit is not replenished (for example, precipitation in the fall is low and near‐surface soils are dry), lake recharge is directly affected, and water availability for the following winter is reduced. In this study, we used snow fences to augment fresh water supplies in shallow arctic lakes despite unfavorable natural conditions. We implemented snow‐control practices to enhance snowdrift accumulation (greater snow water equivalent), which led to increased meltwater production and an extended melting season that resulted in lake recharge despite low precipitation during the years of the experiment. For three years (2009

Remote cameras are an increasingly important tool for ecological research. While remote camera traps collect field data with minimal human attention, the images they collect require post-processing and characterization before it can be ecologically and statistically analyzed, requiring the input of substantial time and money from researchers. The need for post-processing is due, in part, to a high incidence of non-target images. We developed a stand-alone semi-automated computer program to aid in image processing, categorization, and data reduction by employing background subtraction and histogram rules. Unlike previous work that uses video as input, our program uses still camera trap images. The program was developed for an ungulate fence crossing project and tested against an image dataset which had been previously processed by a human operator. Our program placed images into categories representing the confidence of a particular sequence of images containing a fence crossing event. This resulted in a reduction of 54.8% of images that required further human operator characterization while retaining 72.6% of the known fence crossing events. This program can provide researchers using remote camera data the ability to reduce the time and cost required for image post-processing and characterization. Further, we discuss how this procedure might be generalized to situations not specifically related to animal use of linear features.

Fencing is a combat sport whose form of direct confrontation involves hitting the opponent with a weapon. The purpose of the study was to determine the properties of body composition of female representatives of the Polish national fencing team. The study involved 11 female athletes of the Polish national fencing team. Their age was 16-22 years (19±2.32), body weight 52-78 kg (59.7±7.4), body height 158-183 cm (167.46±6.10) and the training experience 7.64±3.47 years. The reference group consisted of 153 students of Warsaw University of Technology (Poland). Twenty basic somatic characteristics were measured. The following indices were calculated: slenderness, Rohrer's, BMI, Manouvrier's, and pelvic-shoulder indices. Density of the body, total body fat, active tissue, the overall profile of body composition and internal proportions of the body were determined. Analysis of internal proportions of factors of the athletes' body composition revealed significant differences in particular groups of features. The total size of the athletes' bodies is due to less-than-average magnitude of the length and stoutness characteristics and a high magnitude of adiposity (M = 0.63) in the Polish female national team of fencers (sabre) calculated from the normalized values for the control group. The proportions of features within the analysed factors revealed a significant advantage of the length of the upper extremity over the lower one and a distinct advantage of forearm musculature. The specific profile of body composition of female athletes practising sabre fencing is most likely due to long-term effects of training as well as the system of selection of persons with specific somatic prerequisites developed in the course of many years of training practice.

Mobile Fences: J.M. Coetzee’s Waiting for the Barbarians

Full Text Available Fences usually enclose and separate, but they are also places of exchange neither inside nor outside. This concept is well represented in J.M. Coetzee’s Waiting for the Barbarians, because not only this novel is setted on the border between an undefined Empire and the barbarians’ lands, but it also plays with various declinations of the idea of limit and boundary. Through a reading which intends to highlight every kind of frame in the novel, it will emerge that no border is fixed and conclusive. Namely, in this book every real or metaphoric fence is called into question: the distinction between the duality of “us and them” is actually determined by the Empire’s walls which separate the inside from the outside in an arbitrary way; the magistrate (with the empathy he feels for the barbarian girl is inevitably caught in a double bind; and, according to Emmanuel Lévinas’ philosophy, the desire to understand otherness reveals its predatory intentions from a post-colonial point of view. It is not possible to delineate an ultimate bordeline, and it will emerge that instead of a binary logic there is a more fruitful way of thinking, a way based on frames, paradoxes and literary texts which cannot be read as flat mirroring devices.

The spread of urban development has dramatically altered natural habitats, modifying community relationships, abiotic factors, and structural features. Animal populations living in these areas must perish, emigrate, or find ways to adjust to a suite of new selective pressures. Those that successfully inhabit the urban environment may make behavioral, physiological, and/or morphological adjustments that represent either evolutionary change and/or phenotypic plasticity. We tested for effects of urbanization on antipredator behavior and associated morphology across an urban-wild gradient in the western fence lizard (Sceloporus occidentalis) in two California counties, Santa Barbara and San Luis Obispo. We compared college campuses in both counties with adjacent rural habitats, conducting field trials that allowed us to characterize antipredator behavior in response to the acute stress of capture. We found notable divergence between campus and rural behavior, with campus lizards more frequently exhibiting diminished escape behavior, including tonic immobility, and lower sprint speeds. Furthermore, campus females had significantly shorter limbs, and while this did not explain variation in sprint speed, those with shorter limbs were more likely to show tonic immobility. We hypothesize that these parallel behavioral and morphological changes on both campuses reflect adjustment to a novel environment involving changes in predation and human presence. PMID:29444102

Highlights: • Hydrothermally-synthesized graphene sponge is excellent skeleton of Li-O 2 cathode. • Fe-N-C catalyst loaded on GS was attained via pyrolysis of FePc and GS composites. • High capacity and good cyclability were achieved with Fe-N-GS air electrode. • The synergy of porous structure and catalytic activity leads to the high performance. - Abstract: The cathode of a lithium-oxygen battery needs the synergism of a porous conducting material and a catalyst to facilitate the formation and decomposition of lithium peroxide. Here we introduce a graphene sponge (GS) modified with Fe-N-C catalyst for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). The porous, 3-dimensional conductive and free standing nature of the graphene sponge makes it become excellent skeleton of cathode for lithium-oxygen battery. The Fe-N-C catalyst nanoparticles dispersed uniformly on the graphene sheets show excellent catalytic reactivity in both discharge and charge processes. This kind of composite material greatly improves the capacity and cyclability of the lithium-oxygen battery. With dimethyl sulphoxide as electrolyte, the capacity reaches 6762 mAh g −1 which is twice of the pure graphene sponge. In addition, the cell containing Fe-N-GS air electrode exhibits stable cyclic performance and effective reduction of charge potential plateau, indicating that Fe-N-GS is promising as an OER catalyst in rechargeable lithium-air batteries

The Eastern fence lizard, Sceloporus undulatus, is widely distributed in eastern and central North America, ranging through areas with high levels of Lyme disease, as well as areas where Lyme disease is rare or absent. We studied the potential role of S. undulatus in transmission dynamics of Lyme spirochetes by sampling ticks from a variety of natural hosts at field sites in central New Jersey, and by testing the reservoir competence of S. undulatus for Borrelia burgdorferi in the laboratory. The infestation rate of ticks on fence lizards was extremely low (proportion infested = 0.087, n = 23) compared to that on white footed mice and other small mammals (proportion infested = 0.53, n = 140). Of 159 nymphs that had fed as larvae on lizards that had previously been exposed to infected nymphs, none was infected with B. burgdorferi, compared with 79.9% of 209 nymphs that had fed as larvae on infected control mice. Simulations suggest that changes in the numbers of fence lizards in a natural habitat would have little effect on the infection rate of nymphal ticks with Lyme spirochetes. We conclude that in central New Jersey S. undulatus plays a minimal role in the enzootic transmission cycle of Lyme spirochetes.

Has computational creativity successfully made it "Beyond the Fence" in musical theatre?

Science.gov (United States)

Jordanous, Anna

2017-10-01

A significant test for software is to task it with replicating human performance, as done recently with creative software and the commercial project Beyond the Fence (undertaken for a television documentary Computer Says Show). The remit of this project was to use computer software as much as possible to produce "the world's first computer-generated musical". Several creative systems were used to generate this musical, which was performed in London's West End in 2016. This paper considers the challenge of evaluating this project. Current computational creativity evaluation methods are ill-suited to evaluating projects that involve creative input from multiple systems and people. Following recent inspiration within computational creativity research from interaction design, here the DECIDE evaluation framework is applied to evaluate the Beyond the Fence project. Evaluation finds that the project was reasonably successful at achieving the task of using computational generation to produce a credible musical. Lessons have been learned for future computational creativity projects though, particularly for affording creative software more agency and enabling software to interact with other creative partners. Upon reflection, the DECIDE framework emerges as a useful evaluation "checklist" (if not a tangible operational methodology) for evaluating multiple creative systems participating in a creative task.

2011-12-01

In order to obtain simultaneously high sample rate and large buffer in data acquisition (DAQ) for a chaos fiber-optic fence system, we developed a double-channel high-speed DAQ application of a digital oscilloscope of PicoScope 5203 based on LabVIEW. We accomplished it by creating call library function (CLF) nodes to call the DAQ functions in the two dynamic link libraries (DLLs) of PS5000.dll and PS5000wrap.dll provided by Pico Technology Company. The maximum real-time sample rate of the DAQ application can reach 1GS/s. We can control the resolutions of the application at the sample time and data amplitudes by changing their units in the block diagram, and also control the start and end times of the sampling operations. The experimental results show that the application has enough high sample rate and large buffer to meet the demanding DAQ requirements of the chaos fiber-optic fence system.

Mitigating Reptile Road Mortality: Fence Failures Compromise Ecopassage Effectiveness

Roadways pose serious threats to animal populations. The installation of roadway mitigation measures is becoming increasingly common, yet studies that rigorously evaluate the effectiveness of these conservation tools remain rare. A highway expansion project in Ontario, Canada included exclusion fencing and ecopassages as mitigation measures designed to offset detrimental effects to one of the most imperial groups of vertebrates, reptiles. Taking a multispecies approach, we used a Before-After-Control-Impact study design to compare reptile abundance on the highway before and after mitigation at an Impact site and a Control site from 1 May to 31 August in 2012 and 2013. During this time, radio telemetry, wildlife cameras, and an automated PIT-tag reading system were used to monitor reptile movements and use of ecopassages. Additionally, a willingness to utilize experiment was conducted to quantify turtle behavioral responses to ecopassages. We found no difference in abundance of turtles on the road between the un-mitigated and mitigated highways, and an increase in the percentage of both snakes and turtles detected dead on the road post-mitigation, suggesting that the fencing was not effective. Although ecopassages were used by reptiles, the number of crossings through ecopassages was lower than road-surface crossings. Furthermore, turtle willingness to use ecopassages was lower than that reported in previous arena studies, suggesting that effectiveness of ecopassages may be compromised when alternative crossing options are available (e.g., through holes in exclusion structures). Our rigorous evaluation of reptile roadway mitigation demonstrated that when exclusion structures fail, the effectiveness of population connectivity structures is compromised. Our project emphasizes the need to design mitigation measures with the biology and behavior of the target species in mind, to implement mitigation designs in a rigorous fashion, and quantitatively evaluate road

2012-07-01

Full Text Available This paper presents a new method for the use of earth-observation images to assess relative land condition over broad regions, using a cross-fence comparison methodology. It controls for natural spatial and temporal variables (e.g. rainfall, temperature soils, ecosystem so that we can objectively monitor rangelands and other areas for the effects of management. The method has been tested with small and large scale theoretical models, as well as a case study in South Australian rangelands. This method can also be applied in other systems and experiments such as field trials of crop varieties as a robust spatial statistic.

Full Text Available Potential Role of Live Fences for Nematode Management on Watersheds in the Senegalese Sudano- Sahelian Area. The influence on the nematode communities of three type of live fences (Zizyphus mauritiana, Bauhinia rufescens and Acacia nilotica was studied in Sinthiou Kohel, in the sudano-sahelian area of Senegal. Numbers of plant parasitic nematode were greater in the vicinity of the live hedge than in the adjacent fields. The effect was apparent to a depth of 40 cm and 2 to 8 m up and downhill. Fewer plant parasitic nematode were recovered from A. nilotica than from the two other plant species. The increase in size of the community was associated with an increase in species diversity, mainly in the Z. mauritiana rhizosphere. Live hedge supported nematode species that were not present in the adjacent fields. Free living nematodes were more abundant under the live fences, whatever the sampling depth. Live fences influenced these nematodes over almost 5 m downhill against only 2 to 3 m uphill. The importance of the live fences, established in this area to prevent erosion, is discussed in relation to their potential for the management of soil parasites and soil fertility factors, that can be transported in runoff water.

Flow characteristics and scaling past highly porous wall-mounted fences

Science.gov (United States)

Rodríguez-López, Eduardo; Bruce, Paul J. K.; Buxton, Oliver R. H.

2017-07-01

An extensive characterization of the flow past wall-mounted highly porous fences based on single- and multi-scale geometries has been performed using hot-wire anemometry in a low-speed wind tunnel. Whilst drag properties (estimated from the time-averaged momentum equation) seem to be mostly dependent on the grids' blockage ratio; wakes of different size and orientation bars seem to generate distinct behaviours regarding turbulence properties. Far from the near-grid region, the flow is dominated by the presence of two well-differentiated layers: one close to the wall dominated by the near-wall behaviour and another one corresponding to the grid's wake and shear layer, originating from between this and the freestream. It is proposed that the effective thickness of the wall layer can be inferred from the wall-normal profile of root-mean-square streamwise velocity or, alternatively, from the wall-normal profile of streamwise velocity correlation. Using these definitions of wall-layer thickness enables us to collapse different trends of the turbulence behaviour inside this layer. In particular, the root-mean-square level of the wall shear stress fluctuations, longitudinal integral length scale, and spanwise turbulent structure is shown to display a satisfactory scaling with this thickness rather than with the whole thickness of the grid's wake. Moreover, it is shown that certain grids destroy the spanwise arrangement of large turbulence structures in the logarithmic region, which are then re-formed after a particular streamwise extent. It is finally shown that for fences subject to a boundary layer of thickness comparable to their height, the effective thickness of the wall layer scales with the incoming boundary layer thickness. Analogously, it is hypothesized that the growth rate of the internal layer is also partly dependent on the incoming boundary layer thickness.

A fence with several safety wires with alarm equipment

International Nuclear Information System (INIS)

Osterburg, G.

1977-01-01

The patent claim concerns a safety arrangement for objects in the open against unauthorised interference. A fence provided with several safety wires is used for this purpose. Each wire has a piezo-electric transmitter at one end, and has a piezo-electric receiver at the other end, which converts the mechanical vibrations into electrical signals. The piezo-electric receiver is connected via an amplifier to the piezo-electric transmitter of the next wire, which initiates the latter to produce mechanical vibrations and so on, until the transmitter of the first wire is reached again, so that a closed feed-back loop is formed. An electronic evaluation circuit is connected between one of the amplfiers and the subsequent transmitter, which on loss of vibration due to touching, hold. (ORU) [de

The Center for Studies and Projects - Naper Solar is an NGO, which works for the dissemination of use of alternative energies resources in the semi-arid Brazilian Northeast in collaboration with the Federal University of Pernambuco. It has implemented caprine raising systems in the back lands of Pajeu in the State of Pernambuco making use of electrified fences energized by solar energy.This project was executed in a joint effort with the City Halls of Afogados da Ingazeira e Sao Jose do Egito and the NGOs Diaconia and the Northeast Woman House and has benefited 20 families of farmers from 9 rural communities. It is funded by a Technical Cooperation Program established between the National Fund for the Environment - Ministry for the Environment and the Netherlands Government. The implemented system, in opposition to the traditional extensive production system, allow for a more animal sanitary control - minimizing the risks of contamination; a more controlled and balanced feeding system - taking into account the weight gaining factor together with pasture management, leading the a guarantee of food supply for the animals. Other advantages of this system include the reduction of fence cost and less deforesting. Electrical fences used in the contention of caprine are built with only 4 straight wires, fixed with isolators on wood posts spaced 10 m from each other, while the conventional fences use 9 barbed-wire lines fixed with clamps on posts spaced 1 m from each other. Therefore, the use of electrical fences instead of the conventional one represent a cost reduction, which can go as high as 40 % of the total cost. Besides that the electrical fences have low maintenance cost, easier and faster installation and relocation. The fenced areas vary from 0.5 ha to 4 ha for the raising of 5 to 50 animals. In the electrification of a fence one needs one photovoltaic module, one electrifier, a battery, isolators (passage and corner), electric ground rods and a thunderbolt

Plasmodium mexicanum is a malaria parasite that naturally infects the western fence lizard, Sceloporus occidentalis , in northern California. We set out to determine whether lizards naturally infected with this malaria parasite have different leukocyte profiles, indicating an immune response to infection. We used 29 naturally infected western fence lizards paired with uninfected lizards based on sex, snout-to-vent length, tail status, and the presence-absence of ectoparasites such as ticks and mites, as well as the presence-absence of another hemoparasite, Schellackia occidentalis. Complete white blood cell (WBC) counts were conducted on blood smears stained with Giemsa, and the proportion of granulocytes per microliter of blood was estimated using the Avian Leukopet method. The abundance of each WBC class (lymphocytes, monocytes, heterophils, eosinophils, and basophils) in infected and uninfected lizards was compared to determine whether leukocyte densities varied with infection status. We found that the numbers of WBCs and lymphocytes per microliter of blood significantly differed (P lizard's immune response to increase the levels of circulating WBCs, but what effect this has on the biology of the parasite remains unclear.

Re-introduction of globally threatened Arabian Gazelles Gazella Arabica (Pallas, 1766 (Mammalia: Bovidae in fenced protected area in central Saudi Arabia

Full Text Available The Arabian Gazelle is a globally threatened antelope (Vulnerable in Saudi Arabia. Small relict populations remain in limited areas, while historically Arabian Gazelles occurred in Mahazat as-Sayd protected area in central Saudi Arabia but were exterminated by anthropogenic and other pressures, including habitat loss and hunting. Important habitat has been lost to agricultural developments, fencing of pasture for livestock and the construction of human settlements and roads. The reintroduction of Arabian Gazelles was undertaken in Mahazat during 2011-2014 to bring back this locally extinct species study its ecology and biology in a fenced protected area. We released a total of 49 (12 males, 37 females animals. A year after release animals started breeding and six calves have been recorded so far with more to come. The gazelles prefer to use more rocky areas where shrubs and acacia trees occur in the reserve, and do not move long distances except for one individual that moved more than 50km. Mahazat is fenced, which prevents local people from entering the reserve to poach or otherwise disturb animals. Management lessons include the need for continued monitor-ing of reintroduced populations. Interactions between Arabian and Sand Gazelles (Gazella subgutturosa marica and Arabian Oryx (Oryx leucoryx were also studied.

Full Text Available Introduction. The aim of this study was to characterise the whole body dynamics and upper and lower joint kinematics during two common fencing steps: the lunge and the fleche. Material and methods. Two male competitive epee fencers were studied. Kinematics data were collected at 120 Hz (BTS Smart system and ground reaction forces were measured at 120 Hz (Kistler platform. The resultant centre of gravity and end segment velocities were calculated. Temporal events were referenced to the horizontal ground reaction force. Time domain linear joint velocities were extracted. Results. At the whole-body level, the resultant centre of gravity velocity was higher during the fleche (2.64 and 2.89 m/s than during the lunge (1.94 and 2.21 m/s. At the joint level, the wrist and elbow attained their peak velocities earlier than the proximal joint for both the lunge and the fleche for both athletes. Conclusions. The sequence of peak segmental velocities followed a distal to proximal sequence for both fencing steps.

AN/FSY-3 Space Fence System – Sensor Site One/Operations Center Integration Status and Sensor Site Two Planned Capability

Science.gov (United States)

Fonder, G. P.; Hack, P. J.; Hughes, M. R.

This paper covers two topics related to Space Fence System development: Sensor Site One / Operations Center construction and integration status including risk reduction integration and test efforts at the Moorestown, NJ Integrated Test Bed (ITB); and the planned capability of Sensor Site Two. The AN/FSY-3 Space Fence System is a ground-based system of S-band radars integrated with an Operations Center designed to greatly enhance the Air Force Space Surveillance network. The radar architecture is based on Digital Beam-forming. This capability permits tremendous user-defined flexibility to customize volume surveillance and track sectors instantaneously without impacting routine surveillance functions. Space Fence provides unprecedented sensitivity, coverage and tracking accuracy, and contributes to key mission threads with the ability to detect, track and catalog small objects in LEO, MEO and GEO. The system is net-centric and will seamlessly integrate into the existing Space Surveillance Network, providing services to external users—such as JSpOC—and coordinating handoffs to other SSN sites. Sensor Site One construction on the Kwajalein Atoll is in progress and nearing completion. The Operations Center in Huntsville, Alabama has been configured and will be integrated with Sensor Site One in the coming months. System hardware, firmware, and software is undergoing integration testing at the Mooretown, NJ ITB and will be deployed at Sensor Site One and the Operations Center. The preliminary design for Sensor Site Two is complete and will provide critical coverage, timeliness, and operational flexibility to the overall system.

In the past three years, two novel synthesis methods for non-precious metal catalysts resulting in a breakthrough of their activity and performance at the cathode of the proton-exchange membrane fuel cell (PEMFC) have been reported by the group of Prof. Dodelet. While the activity of these novel Fe-based catalysts for the oxygen reduction reaction is very high in PEMFC, our preliminary activity measurements with the rotating disk electrode (RDE) technique on one of them showed an activity being a factor 30–100 lower than the one measured in PEMFC at 80 °C. The present work explains to a large extent this huge difference. Two Fe-N-C catalysts synthesized via our novel approaches and one Fe-N-C catalyst synthesized via our classical approach were investigated in RDE and PEMFC. In both systems, the effect of the ink formulation (Nafion-to-catalyst ratio) was investigated. Optimization of the RDE ink formulation explains a factor between 5 and 10 in the two-decade gap mentioned above. Then, the effect of temperature in the RDE system was investigated. An increase from 20 to 80 °C was found to result in a theoretical maximum twofold increase in activity. However, in practice, decreased O 2 solubility with increased temperature cancels this effect. After taking into account these two parameters, a difference in ORR activity between RDE and PEMFC of ca a factor five still remained for one of the two novel Fe-N-C catalysts investigated here. The lower initial activity measured in RDE for this catalyst is shown to be due to the fast adsorption of anions (HSO 4 − ) from the liquid H 2 SO 4 electrolyte on protonated nitrogen atoms (NH + ) found on its surface. The phenomenon of anion adsorption and associated decreased ORR activity also applies to the other novel Fe-N-C catalyst, but is slower and does not immediately occur in RDE.

In this work, a series of hollow carbon nanospheres simultaneously doped with N and Fe-containing species are prepared by Fe3+-mediated polymerization of dopamine on SiO2 nanospheres, carbonization and subsequent KOH etching of the SiO2 template. The electrochemical properties of the hollow nanospheres as nonprecious-metal electrocatalysts for oxygen reduction reaction (ORR) are characterized. The results show that the hollow nanospheres with mesoporous N-doped carbon shells of ~10 nm thickness and well-dispersed Fe3O4 nanoparticles prepared by annealing at 750 °C (Fe/N/C HNSs-750) exhibit remarkable ORR catalytic activity comparable to that of a commercial 20 wt% Pt/C catalyst, and high selectivity towards 4-electron reduction of O2 to H2O. Moreover, it displays better electrochemical durability and tolerance to methanol crossover effect in an alkaline medium than the Pt/C. The excellent catalytic performance of Fe/N/C HNSs-750 towards ORR can be ascribed to their high specific surface area, mesoporous morphology, homogeneous distribution of abundant active sites, high pyridinic nitrogen content, graphitic nitrogen and graphitic carbon, as well as the synergistic effect of nitrogen and iron species for catalyzing ORR.In this work, a series of hollow carbon nanospheres simultaneously doped with N and Fe-containing species are prepared by Fe3+-mediated polymerization of dopamine on SiO2 nanospheres, carbonization and subsequent KOH etching of the SiO2 template.

DuRant, Sarah E.; Hopkins, William A.; Talent, Larry G.

2007-01-01

We examined the effects of a commonly used AChE-inhibiting pesticide on terrestrial and arboreal sprint performance, important traits for predator avoidance and prey capture, in the western fence lizard (Sceloporus occidentalis). Lizards were exposed to carbaryl (2.5, 25, and 250 μg/g) and were raced before and 4, 24, and 96 h after dosing. In the terrestrial setting, exposure to low concentrations of carbaryl had stimulatory effects on performance, but exposure to the highest concentration was inhibitory. No stimulatory effects of carbaryl were noted in the arboreal environment and performance in lizards was reduced after exposure to both the medium and highest dose of carbaryl. Our findings suggest that acute exposure to high concentrations of carbaryl can have important sublethal consequences on fitness-related traits in reptiles and that arboreal locomotor performance is a more sensitive indicator of AChE-inhibiting pesticide poisoning than terrestrial locomotor performance. - Exposure to an acetylcholinesterase-inhibiting pesticide alters locomotor performance in western fence lizards

Catastrophic die-off of globally threatened Arabian Oryx and Sand Gazelle in the fenced protected area of the arid central Saudi Arabia

Directory of Open Access Journals (Sweden)

M.Z. Islam

2010-02-01

Full Text Available A large number of die-off of globally threatened Arabian Oryx (Oryx leucoryx, and Arabian Sand Gazelle (Gazella subgutturosa marica were recorded from 1999 to 2008 in fenced Mahazat as-Sayd Protected Area (PA in western-central Saudi Arabia. Mortalities of animals have been recorded during summer months when the rainfall is negligible or insignificant. Deaths were due to starvation because of reduced availability, accessibility and quality of food plants in the area. In total, 560 oryx and 2815 sand gazelle deaths were recorded since the reintroduction projects began till the end of 2008. Mortalities of animals were higher in 1999-2001, 2006, 2007 and 2008. Grazing of oryx habitat depends on rainfall and animals move over great distances in response to rain. The fence around Mahazat as-Sayd PA prevents natural movements of animals, and artificially concentrates the ungulate populations into possibly unfavourable habitat. The sand gazelle is a highly gregarious and migratory species, moving long distances in search of good quality pastures. Populations of sand gazelle in Central Asia are also known to migrate over large distances, covering several hundred kilometers. It is therefore likely that by preventing natural movements of sand gazelles and oryx, fencing may have reinforced the effects of stressful conditions such as drought. To reduce the catastrophic effects, a Strategy and Action Plan was developed in August 2008 to manage oryx and gazelle within the reserve and with provision for food and water at the five camps in the reserve as emergency plan to minimize mortalities.

Effects of repeated pollutant exposure on growth, locomotor performance, and behavior have rarely been evaluated in reptiles. We administered three doses of malathion (2.0, 20, or 100 mg/kg body weight) to western fence lizards (Sceloporus occidentalis) over an 81 day period. Eight and 23% mortality occurred at 20 and 100 mg/kg (p = 0.079) and 85% of lizards in the 100 mg/kg group exhibited clinical symptoms of poisoning. Growth, food consumption, body condition index, and terrestrial locomotor performance were not significantly influenced by malathion. However, arboreal sprint velocity was significantly reduced in lizards receiving 100 mg/kg. Fifty percent of lizards in the 100 mg/kg group also refused to sprint in the arboreal setting (p = 0.085). Based on these results, arboreal locomotor performance was the most sensitive metric of exposure we evaluated. Further study of compounds such as malathion is warranted due to highly variable application rates and exposure scenarios. - Repeated exposure of western fence lizards to malathion caused reduced arboreal performance and some mortality but growth, food consumption, and terrestrial performance were not affected

Porous carbon supported Fe-N-C composite as an efficient electrocatalyst for oxygen reduction reaction in alkaline and acidic media

Science.gov (United States)

Liu, Baichen; Huang, Binbin; Lin, Cheng; Ye, Jianshan; Ouyang, Liuzhang

2017-07-01

In recent years, non-precious metal electrocatalysts for oxygen reduction reaction (ORR) have attracted tremendous attention due to their high catalytic activity, long-term stability and excellent methanol tolerance. Herein, the porous carbon supported Fe-N-C catalysts for ORR were synthesized by direct pyrolysis of ferric chloride, 6-Chloropyridazin-3-amine and carbon black. Variation of pyrolysis temperature during the synthesis process leads to the difference in ORR catalytic activity. High pyrolysis temperature is beneficial to the formation of the "N-Fe" active sites and high electrical conductivity, but the excessive temperature will cause the decomposition of nitrogen-containing active sites, which are revealed by Raman, TGA and XPS. A series of synthesis and characterization experiments with/without nitrogen or iron in carbon black indicate that the coordination of iron and nitrogen plays a crucial role in achieving excellent ORR performances. Electrochemical test results show that the catalyst pyrolyzed at 800 °C (Fe-N-C-800) exhibits excellent ORR catalytic activity, better methanol tolerance and higher stability compared with commercial Pt/C catalyst in both alkaline and acidic conditions.

Effects of streambank fencing of pasture land on benthic macroinvertebrates and the quality of surface water and shallow ground water in the Big Spring Run basin of Mill Creek watershed, Lancaster County, Pennsylvania, 1993-2001

Streambank fencing along stream channels in pastured areas and the exclusion of pasture animals from the channel are best-management practices designed to reduce nutrient and suspended-sediment yields from drainage basins. Establishment of vegetation in the fenced area helps to stabilize streambanks and provides better habitat for wildlife in and near the stream. This study documented the effectiveness of a 5- to 12-foot-wide buffer strip on the quality of surface water and near-stream ground water in a 1.42-mi2 treatment basin in Lancaster County, Pa. Two miles of stream were fenced in the basin in 1997 following a 3- to 4-year pre-treatment period of monitoring surface- and ground-water variables in the treatment and control basins. Changes in surface- and ground-water quality were monitored for about 4 years after fence installation. To alleviate problems in result interpretation associated with climatic and hydrologic variation over the study period, a nested experimental design including paired-basin and upstream/downstream components was used to study the effects of fencing on surface-water quality and benthic-macroinvertebrate communities. Five surface-water sites, one at the outlet of a 1.77-mi2 control basin (C-1), two sites in the treatment basin (T-3 and T-4) that were above any fence installation, and two sites (one at an upstream tributary site (T-2) and one at the outlet (T-1)) that were treated, were sampled intensively. Low-flow samples were collected at each site (approximately 25-30 per year at each site), and stormflow was sampled with automatic samplers at all sites except T-3. For each site where stormflow was sampled, from 35 to 60 percent of the storm events were sampled over the entire study period. Surface-water sites were sampled for analyses of nutrients, suspended sediment, and fecal streptococcus (only low-flow samples), with field parameters (only low-flow samples) measured during sample collection.

Body condition, diet and ecosystem function of red deer (Cervus elaphus in a fenced nature reserve

Directory of Open Access Journals (Sweden)

Camilla Fløjgaard

2017-07-01

Full Text Available Body condition, as a sign of animal welfare, is of management concern in rewilding projects where fenced animals are subject to winter starvation, which may conflict with animal welfare legislation. Investigating the relationship between body condition, age, sex, diet quality and diet composition is therefore relevant to increase understanding of herbivores' ecosystem function and to inform management. In this study, we focused on red deer, Cervus elaphus, in a fenced nature reserve in Denmark, where the deer are managed as ecosystem engineers to contribute to biodiversity conservation. We measured body mass and body size of 91 culled red deer, and determined diet composition using DNA metabarcoding and diet quality using fecal nitrogen on 246 fecal samples. We found that body condition was predicted by age and diet composition, but not diet quality. We also found that individuals of different body condition had different diets, i.e., the fecal samples of red deer in poorer body condition contained significantly more Ericaceae sequences than red deer in good body condition. This may imply that certain functions of red deer in ecosystems, such as regeneration of heather by grazing, may depend on variation in body condition within the population. Our findings call for the need to consider the consequences of management practices, including culling or supplemental feeding, on the outcomes of habitat restoration, and more broadly underline the importance of preserving the overall breath of herbivore ecosystem functions for effective biodiversity conservation.

Full Text Available Geo-fencing (geofencing is a great feature in a software program that uses Global Positioning System (GPS or radio frequency identification (RFID to define the geographical boundaries feature. Actually geofence is a virtual barrier. Geofencing is an innovative technology, an online marketplace for proactive contextual services that allows users to easily find interesting services, can easily subscribe to it and to allow providers offer their services for a variety of applications such as electronic toll collection, contextual advertising or tourist information systems, even without additional infrastructure. The main objective of this research was to understand how the use of spatial data can improve advertising performance for customers. Tracking systems and monitoring, based on global navigation services by satellite, and include geofencing function, could also contribute to the exact location of an institution or company and increase sales and business perspective efficiently. Instead of large billboards they can now advertise on smartphones which is economically and accurately tested. Therefore, we have developed a concept for a market that offers geofence, which can be applied by all and increase the use and integration of proactive services based on location in everyday life.

How Fencing Affects the Soil Quality and Plant Biomass in the Grassland of the Loess Plateau.

Science.gov (United States)

Zeng, Quanchao; Liu, Yang; Xiao, Li; Huang, Yimei

2017-09-25

Overgrazing is a severe problem in several regions in Northwestern China and has caused serious land degradation. Secondary natural succession plays an important role in the accumulation of soil carbon and nitrogen contents. Estimating the effects of grazing exclusion on soil quality and plant diversity will improve our understanding of the succession process after overgrazing and promote judicious management of degraded pastures. This experiment was designed to measure soil properties and plant diversity following an age chronosequence of grasslands (ages ranged from one year, 12 years, 20 years, and 30 years) in Northwestern China. The results showed that continuous fencing resulted in a considerable increase in plant coverage, plant biomass (above- and below-ground biomass), and plant diversity, which can directly or indirectly improve the accumulation of soil organic carbon and total nitrogen content. The plant coverage and the above- and below-ground biomass linearly increased along the succession time, whereas soil organic C and N contents showed a significant decline in the first 12 years and, subsequently, a significant increase. The increased plant biomass caused an increase in soil organic carbon and soil total nitrogen. These results suggested that soil restoration and plant cover were an incongruous process. Generally, soil restoration is a slow process and falls behind vegetation recovery after grazing exclusion. Although the accumulation of soil C and N stocks needed a long term, vegetation restoration was a considerable option for the degraded grassland due to the significant increase of plant biomass, diversity, and soil C and N stocks. Therefore, fencing with natural succession should be considered in the design of future degraded pastures.

Plutonium assessment modeling: government policy, non-proliferation, and the government fence

Kurstedt, H.A. Jr.; Nachlas, J.A.

1977-01-01

Assessment modeling for the evaluation of plutonium as an energy resource is stressed, and generic mathematical model forms are outlined. Representative necessary objective functions are developed. Constraints and assumptions are listed. An example involving present-day light water reactor technology is demonstrated. Technical, environmental, and political implications are drawn. Specific new directions for analysis are suggested. The position of the boundary of government control and responsibility--the government exclusion fence--is shown to be a critical, but overlooked, constraint. Existing governmental uranium stockpiles may be an unmentioned, though important, constraint. Plutonium is the most abundant proven energy equivalent and most controversial energy resource. Plutonium results from an intermediate nuclear reactor processing stage starting with the raw material 238 U. Therefore, the plutonium resource differs from the 238 U resource only through minimal conversion losses and through the political and/or social will to perform the conversion. The relative abundance of 238 U, and therefore of plutonium is high. There is a great need to assess plutonium in relation to the potential available energy for a society in short supply

Developing an Ethically Acceptable Virtual Fencing System for Sheep

Directory of Open Access Journals (Sweden)

Danila Marini

2018-02-01

Full Text Available To ensure animal welfare isn’t compromised when using virtual fencing, animals must be able to associate a benign conditioned stimulus with an aversive stimulus. This study used an associative learning test to train 30, four-year-old, Merino x Suffolk ewes, to associate an audio cue with an electric stimulus. Collars manually controlled by a GPS hand-held unit were used to deliver the audio and electric stimuli cues. For the associative learning, when sheep approached an attractant at a distance of three m from the trough, an audio cue was applied for one s. If the sheep stopped or changed direction, the audio cue ceased immediately and no electrical stimulus was applied. If the sheep did not respond to the audio cue it was followed by a low-level electrical stimulus. Approaches to the attractant significantly decreased from day one to day two. It took a mean of three pairings of the audio cue and electrical stimulus for a change in behaviour to occur, after which sheep that approached the attractant had a 52% probability of avoiding the electrical stimulus and responding to the audio cue alone. Further research is required to determine whether sheep can be trained to associate an audio cue with a negative stimulus for use in group grazing situations.

Purpose: The purpose of this study is to propose a new non-imaging method to localize the radiation isocenter with submillimeter accuracy. Methods: The Vernier picket fence (VPF) is a multileaf collimator (MLC) picket fence sequence in which the fence spacing is 1/N smaller than the detector spacing of the QA phantom, where N is the magnification factor, typically set to 10 or 20. Similar to reading a Vernier caliper, the user can easily achieve the resolution of 1/N of the detector spacing by visually inspecting the maximum signal. To achieve higher accuracy, a Gaussian model was used to interpolate the peak position, which can fall between adjacent detectors. In two separate tests, precise MLC offsets and imprecise couch offsets were applied to a 2D detector array (MapCheck, Sun Nuclear Corp., Melbourne, Florida) to introduce setup errors. Two vertical VPF fields were delivered with collimator angles at 0° and 90° to detect the lateral and longitudinal setup errors, respectively. For a rotational QA phantom, an additional lateral VPF field is needed to detect the vertical setup error for three-dimensional capabilities. Results: With N set to 20 and a detector spacing of 5 mm for MapCheck, the resolution of the VPF’s visual analysis is 0.25 mm. With the Gaussian interpretation, the VPF can achieve an accuracy of 0.02 mm, as shown by the MLC offset test. The couch offset test measured the couch hysteresis and demonstrated that the setup error detected by the VPF differed from the ExacTrac™ (Brainlab AG, Feldkirchen, Germany) optical tracking by 0.055 mm in the lateral direction and 0.041 mm in the longitudinal direction on average. The VPF was also shown to be feasible in the vertical direction as well. Conclusion: This study verified the VPF as a non-imaging method to localize the radiation isocenter with submillimeter accuracy.

High-energy non-missile penetrating injuries (stab injuries) account for a small percentage of penetrating head injuries and they present a series of special features. A 35-year-old man suffered orbito-frontal? and trans-cranial injuries after falling five meters from a terrace onto a rod iron fence. The removal of the metal rod was performed outside the operating room. The orbital roof was exposed and repaired through a bifrontal craniotomy and the frontal sinuses were cranialised. The orbital floor and zygoma were plated with micro-screws. The patient recovered without significant complications, apart from a slight paresis of the right superior rectus; the ocular globe remained intact.The positive outcome obtained in this very challenging case is attributable to the competency of the Neurotrauma Unit and to the use of a synergistic approach which involved the contribution of neurosurgeons, maxillo-facial surgeons, radiologists and anaesthesiologists.

The Failure of the American Dream in August Wilson's Fences

Full Text Available This paper traces the impossibility of the fulfillment of the American dream for AfricanAmericans in August Wilson‟s Fences. It examines why Troy Maxon, as the protagonist of the play, is not able to fulfill his dreams of freedom, and economic achievements in an environment of oppression where he finds himself surrounded by hostile whites who hinder his development. It indicates that the racial discrimination, manifested in various forms including racial segregation prevalent in the white-dominated American society, impedes Troy‟s progress. A large number of African-Americans migrated from southern states to the north in 1920s and 1930s in order to find jobs in industrial northern states. They had been told that the United States was the promised land of equal chances wherein everyone regardless of race and gender was able to progress from rags to riches. They left the South, in which racism was still pervasive despite the abolition of slavery, and moved to the North for the fulfillment of the dreams they had been promised. The advocates of the American Dream claimed that hard diligence and intelligence could lead a man to material prosperity. Nevertheless, this paper demonstrates that since African-Americans are considered to be „„others‟‟ in the white dominated society, financial progress and other aspects of the American Dream remain impossible dreams for them.

setting up barriers in a form of fence, especially that in Balinese traditional architecture. The research aims to study the effectiveness of different kinds of fence and to study the effects of these fences and the number of vehicles on the noise level produced. The research was conducted based on the (ISO R 1996 standard, namely the equivalence of noise level of n number of sample. It adopted a purposive sampling select the type of barrier, and focused on the following research objects: (1 type of fence, (2 distance of measurement from a noise source, and (3 type number of vehicles. The effectiveness of a barrier is expressed in the amount of noise reduction from a noise, either with or without barrier, and the coefficient of muting from each barrier. The tests to analyze the data are the correlation test to know the effectiveness of barrier and the regression test to know the kind of relationship between the type of vehicle and the noise level. The research found that a massive fence is the most effective noise reducer among different tyes of fence, with coefficient of 0.12. However, it offers less aesthetic element as it gives a impression of individualsm in addition to its structure that obstructs the eyes to see what is happening ourtside. A fence with gaps covered with vegetation is better both from the esthetic point of view and from physical function that is to reduce noise, with a coefficient of 0.09. The relation between the noise level and the number of vehicle can be identified by using a linear equation approach by putting the equivalence of the number of vehicle with that of motorcycle.

The aim of this study was to assess habits related to eating meals in children and adolescents who attended sports schools. The days with training and the days free of training were analysed separately. The questionnaires on the number and frequency of eating meals were filled in by 141 children and adolescents who practised fencing and attended sports classes in primary and secondary schools. The influence of gender and age on the number and frequency of eating meals was analysed by means of the SPSS 12.0 PL for Windows computer programme. The studied children's and adolescents' habits related to eating meals were highly unfavourable, especially in females from secondary school, mainly due to a very low percentage of students who ate meals regularly, lunch in particular. Boys ate more meals than girls. Especially disconcerting was a very low number of meals eaten by females from secondary school, which may imply a risk of anorexia. Children and adolescents who attend sports schools should be educated on nutrition and the relation between food habits, nutritional status and achieving success in sport. Females from secondary schools should be informed about the danger of anorexia.

Full Text Available Three Didelphis marsupialis were radio tracked during late dry season (23 February-26 April, 1983 in agricultural area at 1500 m elevation in Central Valley, Costa Rica. All animals were nocturnally active, significantly more so between 2100-0300 h. Fifty diurnal den site locations were found, 96% inside tree cavities in living fence rows or abandoned squirrel nests in windbreaks. Two females occupied 3.4 and 3.1 ha 95% home ranges, moving an average 890 and 686 m nightly respectively. The male occupied a 5.6 ha 95% home range for 42 days overlapping 90% of females' home ranges. Over the next 15 days, he moved 1020 m south, establishing three temporary home ranges. During nocturnal movements, windbreaks and living fence rows were used in higher proportion than available, while pasture, roads and cultivated lands were used less then available within 100% home ranges. Abandoned coffee and spruce plantations, fruit orchards and overgrown pastures were used in equal proportions to availability in 100% home ranges. Opossum conservation techniques in coffee growing areas include promoting spruce windbreaks, living fence rows, and garbage dumps.

Ambient temperature can influence tick development time, and can potentially affect tick interactions with pathogens and with vertebrate hosts. We studied the effect of ambient temperature on duration of attachment of larval blacklegged ticks, Ixodes scapularis Say, to eastern fence lizards, Sceloporus undulatus (Bosc & Daudin). Feeding periods of larvae that attached to lizards under preferred temperature conditions for the lizards (WARM treatment: temperatures averaged 36.6°C at the top of the cage and 25.8°C at the bottom, allowing behavioral thermoregulation) were shorter than for larvae on lizards held under cool conditions (COOL treatment temperatures averaged 28.4°C at top of cage and 24.9°C at the bottom). The lizards were infested with larvae four times at roughly monthly intervals. Larval numbers successfully engorging and dropping declined and feeding period was longer after the first infestation. © 2014 Entomological Society of America.

The strength and arrangement of movement barriers can impact the connectivity among habitat patches. Anthropogenic barriers (e.g. roads) are a source of habitat fragmentation that can disrupt these resource networks and can have an influence on the spatial genetic structure of populations. Using microsatellite data, we evaluated whether observed genetic structure of moose (Alces alces) populations were associated with human activities (e.g. roads) in the urban habitat of Anchorage and rural habitat on the Kenai Peninsula, Alaska. We found evidence of a recent genetic subdivision among moose in Anchorage that corresponds to a major highway and associated infrastructure. This subdivision is most likely due to restrictions in gene flow due to alterations to the highway (e.g. moose-resistant fencing with one-way gates) and a significant increase in traffic volume over the past 30 years; genetic subdivision was not detected on the Kenai Peninsula in an area not bisected by a major highway. This study illustrates that anthropogenic barriers can substructure wildlife populations within a few generations and highlights the value of genetic assessments to determine the effects on connectivity among habitat patches in conjunction with behavioral and ecological data..

Full Text Available En Centro América, los paisajes agropecuarios mantienen diferentes formas de cobertura arbórea como árboles dispersos, cercas vivas, fragmentos de bosque, bosques ribereños, que pueden generar hábitats apropiados para la conservación de la biodiversidad. El presente estudio caracterizó la composición, riqueza y abundancia de mariposas en dos tipos de cercas vivas presentes en un paisaje dominado por pasturas en el Pacifico Central de Costa Rica. Se seleccionaron un total de cinco cercas vivas por cada tipo de cerca (simples y multiestrato, donde se establecieron franjas de 120x5m que fueron recorridos por espacio de una hora durante dos días/hábitat. Se registró un total de 2 782 individuos, pertenecientes a 75 especies de mariposas. Las especies más abundantes fueron: Anartia fatima, Eurema daría, E. nise, Hermeuptychia hermes, Junonia evarete y Phoebis philea. Las cercas vivas multiestrato presentaron una mayor riqueza y abundancia de especies de mariposas que las cercas vivas simples. Las cercas vivas multiestrato pueden ayudar a mantener el 56% de las especies encontradas en los bosques secundarios y ribereños. Este tipo de cerca viva pueden jugar un papel importante para la conservación de mariposas en áreas de producción pecuaria, y su beneficio está influenciado por el tipo manejo que realizan los productores.Do live fences help conserve butterfly diversity in agricultural landscapes?

Due to the high cost and limited availability of platinum, the development of non-platinum-group metals (non-PGM) catalysts is of paramount importance. A promising alternative to Pt are Fe-N-C-based materials. Here we present the synthesis, characterization and electrochemistry of a template-free nitrogen-doped carbon foam, impregnated with iron. This low-cost and gram-scale method results in materials with micron-scale pore size and large surface area (1600 m2g-1). When applied as an oxygen reduction reaction (ORR) electrocatalyst in alkaline solution, the Fe-N-C foams display extremely high initial activity, slightly out-performing commercially available non-PGM catalysts (NCP-2000, Pajarito Powder). The load-cycle durability in alkaline solution is investigated, and the performance steadily degrades over 60,000 potential cycles, whilst the commercial catalyst is remarkably stable. The post-operation catalyst microstructure is elucidated by transmission electron microscopy (TEM), to provide insight into the degradation processes. The resulting images suggest that potential cycling leads to leaching of atomically dispersed Fe-N2/4 sites in all the catalysts, whereas encapsulated iron nanoparticles are protected.

The aim of this study was to assess the longest interval between meals, eating until the feeling of satiety and eating between meals in children and adolescents who attended sports schools. The questionnaires on were filled in by 141 children and adolescents who practised fencing and attended sports classes in primary and secondary schools. The days with training and the days free of training were analysed separately. The influence of gender and age on the longest interval between meals, eating until the feeling of satiety and eating between meals on the days with training and the days free of training was analysed by means of the SPSS 12.0 PL for Windows computer programme. Gender and age had statistically significant influence on the longest interval between meals, eating until the feeling of satiety and eating vegetables, cured meat, sweets and energy drinks between meals. Eating between main meals was prevalent in the studied population. Higher percentage of girls ate fruit and vegetables between main meals, while higher percentage of boys ate sandwiches, irrespectively of the type of the day--with training or free of training.

Immune responses of eastern fence lizards (Sceloporus undulatus) to repeated acute elevation of corticosterone.

McCormick, Gail L; Langkilde, Tracy

2014-08-01

Prolonged elevations of glucocorticoids due to long-duration (chronic) stress can suppress immune function. It is unclear, however, how natural stressors that result in repeated short-duration (acute) stress, such as frequent agonistic social encounters or predator attacks, fit into our current understanding of the immune consequences of stress. Since these types of stressors may activate the immune system due to increased risk of injury, immune suppression may be reduced at sites where individuals are repeatedly exposed to potentially damaging stressors. We tested whether repeated acute elevation of corticosterone (CORT, a glucocorticoid) suppresses immune function in eastern fence lizards (Sceloporus undulatus), and whether this effect varies between lizards from high-stress (high baseline CORT, invaded by predatory fire ants) and low-stress (low baseline CORT, uninvaded) sites. Lizards treated daily with exogenous CORT showed higher hemagglutination of novel proteins by their plasma (a test of constitutive humoral immunity) than control lizards, a pattern that was consistent across sites. There was no significant effect of CORT treatment on bacterial killing ability of plasma. These results suggest that repeated elevations of CORT, which are common in nature, produce immune effects more typical of those expected at the acute end of the acute-chronic spectrum and provide no evidence of modulated consequences of elevated CORT in animals from high-stress sites.

Full Text Available We analyzed the participations and the rankings of the different European states in the 2012 Europen Championship. The diversity, which fencing brings with it in United Europe always attracts a lot of the attention of the sport public as an innovative and dynamic sport discipline. In this article the total number of contestants and the number of contestants in the different weapons for both sexes are monitored. We found that the most competitive disciplines were epee men discipline with 92 participants and epee women discipline with 75 participants, and the least competitive – foil women discipline with 40 participants. The nation that won the biggest number of medals was Russia with total of 8 medals 4 of wich golden. The first three states ranked by the competitors in the top sixteen group for all weapons are as follows: Russia with 16%, Italy with 15% and Germany with 13%. After observing the technics most widely used by the most successful contestants in this competition we reached to the followig recommendations for Bulgarian fencers to perform better: 1. For a better ranking to be achieved it is necessary attention to be paid on improving the technics of attack, using movements of high difficulty and speed and 2. It is important to improve dramatically the quality of both the attack and the defence.

Direct methanol fuel cells (DMFCs) offer great advantages for the supply of power with high efficiency and large energy density. The search for a cost-effective, active, stable and methanol-tolerant catalyst for the oxygen reduction reaction (ORR) is still a great challenge. In this work, platinum group metal-free (PGM-free) catalysts based on Fe-N-C are investigated in acidic medium. Post-treatment of the catalyst improves the ORR activity compared with previously published PGM-free formulations and shows an excellent tolerance to the presence of methanol. The feasibility for application in DMFC under a wide range of operating conditions is demonstrated, with a maximum power density of approximately 50 mW cm(-2) and a negligible methanol crossover effect on the performance. A review of the most recent PGM-free cathode formulations for DMFC indicates that this formulation leads to the highest performance at a low membrane-electrode assembly (MEA) cost. Moreover, a 100 h durability test in DMFC shows suitable applicability, with a similar performance-time behavior compared to common MEAs based on Pt cathodes. © 2016 WILEY-VCH Verlag GmbH & Co.

2006-08-01

The western fence lizard, Sceloporus occidentalis, is refractory to experimental infection with Borrelia burgdorferi sensu stricto, one of several Lyme disease spirochetes pathogenic for humans. Another member of the Lyme disease spirochete complex, Borrelia bissettii, is distributed widely throughout North America and a similar, if not identical, spirochete has been implicated as a human pathogen in southern Europe. To determine the susceptibility of S. occidentalis to B. bissettii, 6 naïve lizards were exposed to the feeding activities of Ixodes pacificus nymphs experimentally infected with this spirochete. None of the lizards developed spirochetemias detectable by polymerase chain reaction for up to 8 wk post-tick feeding, infected nymphs apparently lost their B. bissettii infections within 1-2 wk after engorgement, and xenodiagnostic L. pacificus larvae that co-fed alongside infected nymphs did not acquire and maintain spirochetes. In contrast, 3 of 4 naïve deer mice (Peromyscus maniculatus) exposed similarly to feeding by 1 or more B. bissettii-infected nymphs developed patent infections within 4 wk. These and previous findings suggest that the complement system of S. occidentalis typically destroys B. burgdorferi sensu lato spirochetes present in tissues of attached and feeding I. pacificus nymphs, thereby potentially reducing the probability of transmission of these bacteria to humans or other animals by the resultant adult ticks.

In this work, a category of Fe3C-containing Fe/N/C mesoporous material has been fabricated by carbonizing the mixture of uric acid, Iron (Ⅲ) chloride anhydrous and carbon support (XC-72) under different pyrolysis temperature. Of all these samples, pyrolysis temperature (800 °C) becomes the most crucial factor in forming Fe3C active sites which synergizes with high content of graphitic N to catalyze oxygen reduction reaction (ORR). X-ray absorption fine structure spectroscopy (XAFS) is used to exhibit that the space structure around Fe atoms in the catalyst. This kind of catalyst possesses comparable ORR properties with commercial 20% Pt/C (onset potential is 0 V vs. Ag/AgCl in 0.1 M KOH), the average transfer electron number is 3.84 reflecting the 4-electron process. Moreover, superior stability and methanol tolerance deserve to be mentioned.

Evaluation of toxic metals in the industrial effluents and their segregation through peanut husk fence for pollution abatement

International Nuclear Information System (INIS)

Husaini, S.N.; Zaidi, J.H.; Matiullah; Akram, M.

2011-01-01

The industrial pollution is exponentially growing in the developing countries due to the discharge of untreated effluents from the industries in the open atmosphere. This may cause severe health hazards in the general public. To reduce this effect, it is essential to remove the toxic and heavy metals from the effluents before their disposal into the biosphere. In this context, samples of the effluents were collected from the textile/yarn, ceramics and pulp/paper industries and the concentrations of the toxic metal ions were determined using neutron activation analysis (NAA) technique. The observed concentration values of the As, Cr and Fe ions, in the unprocessed industrial effluents, were 4.91 ± 0.8, 9.67 ± 0.7 and 9.71 ± 0.8 mg/L, respectively which was well above the standard recommended limits (i.e. 1.0, 1.0 and 2.0 mg/L, respectively). In order to remove the toxic metal ions from the effluents, the samples were treated with pea nut husk fence. After this treatment, 91.5% arsenic, 81.9% chromium and 66.5% iron metal ions were successfully removed from the effluents. Then the treated effluents contained concerned toxic metal ions concentrations within the permissible limits as recommended by the national environmental quality standards (NEQS). (author)

This work reports results of the application of electrokinetic fence technology in a 32 m 3 -prototype which contains soil polluted with 2,4-D and oxyfluorfen, focusing on the evaluation of the mechanisms that describe the removal of these two herbicides and comparing results to those obtained in smaller plants: a pilot-scale mockup (175 L) and a lab-scale soil column (1 L). Results show that electric heating of soil (coupled with the increase in the volatility) is the key to explain the removal of pollutants in the largest scale facility while electrokinetic transport processes are the primary mechanisms that explain the removal of herbicides in the lab-scale plant. 2-D and 3-D maps of the temperature and pollutant concentrations are used in the discussion of results trying to give light about the mechanisms and about how the size of the setup can lead to different conclusions, despite the same processes are occurring in the soil.

BARRIER DESIGN STRATEGIES TO CONTROL NOISE INGRESS INTO DOMESTIC BUILDINGS

Directory of Open Access Journals (Sweden)

2003-01-01

Full Text Available Noise source for buildings adjacent to streets is traffic-generated predominantly. Where people are mostly spend their time indoors, it is important for buildings to have screening or blocking to control noise intrusion into living spaces. But this blocking should also permit airflow. This is important for middle to low-cost domestic buildings, which do not employ conditioned ventilation. A common feature of Indonesian buildings, fence, is studied to perform noise barrier. The fence -a barrier to be- should obey three factors: position, dimension, and material. All these three factors were studied to seek compromised design for acoustic performance and natural ventilation purpose. Domestic building situated in the urban area of Yogyakarta was studying to see the most possible design of the barrier to be. There are two calculation methods employed to investigate the proposed design. The study shows that it is possible to gain minimum of 10 dB noise reduction by placing windows within the shadow effect of approximately 1.5 height fence-barrier.

Indigenous Australian Texts in European English Departments: A Fence, a Bridge and a Country as an Answer to the Debate over Multiculturalism

Directory of Open Access Journals (Sweden)

Iva Polak

2013-05-01

Full Text Available Though non-canonical Anglophone courses in the curriculum of European English departments are no longer seen as oddity, they are often regarded as “marginal” in comparison to the British and American canon. However, courses focusing on the cultural output of postcolonial voices, moreover of the most marginal of postcolonial voices, do not only challenge the extent to which we have managed to shift from Eurocentrism in literary theory, but also reveal the complexities of the current cultural trends, such as the frequently evoked policy of multiculturalism. The paper argues that courses which include texts by Indigenous Australian authors reveal the story of survival in a country that is literally multicultural, and stress the importance of one’s own place of utterance, which is as local as it is global. The above issues are exemplified by the works of the famous Aboriginal writers Doris Pilkington/Nugi Garimara (Follow the Rabbit-Proof Fence, 1996, John Muk Muk Burke (Bridge of Triangles, 1994 and Alexis Wright (Carpentaria, 2006.

The effect of deltamethrin-treated net fencing around cattle enclosures on outdoor-biting mosquitoes in Kumasi, Ghana.

Directory of Open Access Journals (Sweden)

Marta Ferreira Maia

Full Text Available Classic vector control strategies target mosquitoes indoors as the main transmitters of malaria are indoor-biting and -resting mosquitoes. However, the intensive use of insecticide-treated bed-nets (ITNs and indoor residual spraying have put selective pressure on mosquitoes to adapt in order to obtain human blood meals. Thus, early-evening and outdoor vector activity is becoming an increasing concern. This study assessed the effect of a deltamethrin-treated net (100 mg/m(2 attached to a one-meter high fence around outdoor cattle enclosures on the number of mosquitoes landing on humans. Mosquitoes were collected from four cattle enclosures: Pen A - with cattle and no net; B - with cattle and protected by an untreated net; C - with cattle and protected by a deltamethrin-treated net; D - no cattle and no net. A total of 3217 culicines and 1017 anophelines were collected, of which 388 were Anopheles gambiae and 629 An. ziemanni. In the absence of cattle nearly 3 times more An. gambiae (p<0.0001 landed on humans. The deltamethrin-treated net significantly reduced (nearly three-fold, p<0.0001 culicine landings inside enclosures. The sporozoite rate of the zoophilic An. ziemanni, known to be a secondary malaria vector, was as high as that of the most competent vector An. gambiae; raising the potential of zoophilic species as secondary malaria vectors. After deployment of the ITNs a deltamethrin persistence of 9 months was observed despite exposure to African weather conditions. The outdoor use of ITNs resulted in a significant reduction of host-seeking culicines inside enclosures. Further studies investigating the effectiveness and spatial repellence of ITNs around other outdoor sites, such as bars and cooking areas, as well as their direct effect on vector-borne disease transmission are needed to evaluate its potential as an appropriate outdoor vector control tool for rural Africa.

Full Text Available Abstract Background No published data is currently available that describes the dietary patterns or physiological profiles of athletes participating on the Kuwaiti national fencing team and its potential impact on health and physical performance. The purpose of this investigation was to: 1 collect baseline data on nutrient intake 2 collect, analyze and report baseline for body composition, plasma lipid and lipoprotein concentrations during the competitive season, 3 compare the results with the international norms, 4 and provide necessary health and nutritional information in order to enhance the athletes' performance and skills. Methods Fifteen national-class fencers 21.5 ± 2.6 years of age participated in this study. Food intake was measured using a 3-day food record. Body composition was estimated using both the BOD POD and Body Mass Index (BMI. Total blood lipid profiles and maximum oxygen consumption was measured for each of the subjects during the competitive season. Results The results of the present study showed significant differences in dietary consumption in comparison with the recommended dietary allowances (RDA. The blood lipids profile and body composition (BMI and % body fat were in normal range in comparison with international norms However, the average VO2 max value was less than the value of the other fencers. Conclusion Due to the results of the research study, a dietary regimen can be designed that would better enhance athletic performance and minimize any health risks associated with nutrition. Percent body fat and BMI will also be categorized for all players. In addition, the plasma blood tests will help to determine if any of the players have an excessive level of lipids or any blood abnormalities. The outcomes of present study will have a direct impact on the players health and therefore their skills and athletic performance.

The impact of male contraception on dominance hierarchy and herd association patterns of African elephants (Loxodonta africana in a fenced game reserve

Directory of Open Access Journals (Sweden)

L.S. Doughty

2014-12-01

Full Text Available Overpopulation of African elephants (Loxodonta africana in fenced reserves in South Africa is becoming increasingly problematic to wildlife managers. With growing opposition to culling and the high cost of translocation, alternative management strategies focusing on male elephants are being investigated. In this study, hormonal treatment via Gonadotropin Releasing Hormone (GnRH suppression, and surgical treatment via vasectomy were trialled. Focusing on behavioural responses, we tested the male dominance hierarchy for transitivity, and examined the rank order of individuals in relation to age and contraceptive treatment received. Additionally, we studied association patterns between males within the male population and with the female herds.Findings suggest that the treatment of one individual with GnRH suppressant is affecting the rank order of the dominance hierarchy, though it is still transitive, yet fluid (Landau’s linearity index h=0.7, as expected in a normal elephant population. Between males, association patterns were found to be weak. However, some males had relatively strong associations with the female herds, with association indices between 0.25 and 0.41. This suggests that the reduction on births is resulting in the males spending atypically large amounts of time with the female herds. The future conservation implications of this population control mechanism are discussed.

Dynamic response of woody vegetation on fencing protection in semi-arid areas; Case study: Pilot exclosure on the Firmihin Plateau, Socotra Island

Directory of Open Access Journals (Sweden)

Hana Habrova

2017-02-01

Full Text Available Woody vegetation dynamics and Dracaena cinnabari regeneration have been studied for five years in the conditions of Socotra Island. Woody plants were measured regularly inside and outside the exclosure area, and the growth and survival of D. cinnabari seedlings were observed. In the exclosure of about 1000 m2 a total of 49 species were identified, including 23 endemics, growing in the average density of 3.82 specimens per m2. The fenced area was overgrown relatively rapidly by dense grass cover – reaching approx. 2.7 t/ha. Species growth dynamics inside and outside the exclosure shows that grazing had a marked impact, leading to the elimination of trees and shrubs. All grazed species grew noticeably in the exclosure, in the average of 50 cm in 5 years. D. cinnabari as the dominant flagship species of Socotra has been studied with regards to regeneration dynamics. Observations indicate that probability of its seedlings survival increases with their age. No seedlings germinated from the seeds sown in the experiment, however, outplanted seedlings performed relatively well. Field observations show that D. cinnabari seed germination is triggered when the seed reaches a protected micro-habitat with a developed humus layer and high relative humidity in the soil lasts for at least two days.

Liveness redux: on media and their claim to be live.

Science.gov (United States)

van Es, Karin

2017-11-01

Increasingly media are asserting themselves as live. In television, this has been an important strategy and recently it has been employed by new media platforms such as Facebook, Periscope and Snapchat. This commentary explains the revival of live media by exploring the meaning and operations of the concept and argues the continued relevance of the concept for the study of social media. Traditionally, there have been three main approaches to the live in academic writing (i.e. liveness as ontology, as phenomenology and as rhetoric): each has its particular shortcoming. This paper proposes that it is more productive to understand the live as a construction that assists to secure media a central role in everyday life.

This work describes the application electrokinetic fence technology to a soil polluted with herbicides in a large prototype containing 32 m 3 of soil. It compares performance in this large facility with results previously obtained in a pilot-scale mockup (175 L) and with results obtained in a lab-scale soil column (1 L), all of them operated under the same driving force: an electric field of 1.0 V cm -1 . Within this wide context, this work focuses on the effect on inorganic species contained in soil and describes the main processes occurring in the prototype facility, as well as the differences observed respect to the lower scale plants. Thus, despite the same processes can be described in the three plants, important differences are observed in the evolution of the current intensity, moisture and conductivity. They can be related to the less important electroosmotic fluxes in the larger facilities and to the very different distances between electrodes, which lead to very different distribution of species and even to a very different evolution of the resulting current intensity. 2-D maps of the main species at different relevant moments of the test are discussed and important information is drawn from them. Ions depletion from soil appears as a very important problem which should be prevented if the effect of natural bioremediation and/or phytoremediation on the removal or organics aims to be accounted.

Divergent discourse between protests and counter-protests: #BlackLivesMatter and #AllLivesMatter.

Gallagher, Ryan J; Reagan, Andrew J; Danforth, Christopher M; Dodds, Peter Sheridan

2018-01-01

Since the shooting of Black teenager Michael Brown by White police officer Darren Wilson in Ferguson, Missouri, the protest hashtag #BlackLivesMatter has amplified critiques of extrajudicial killings of Black Americans. In response to #BlackLivesMatter, other Twitter users have adopted #AllLivesMatter, a counter-protest hashtag whose content argues that equal attention should be given to all lives regardless of race. Through a multi-level analysis of over 860,000 tweets, we study how these protests and counter-protests diverge by quantifying aspects of their discourse. We find that #AllLivesMatter facilitates opposition between #BlackLivesMatter and hashtags such as #PoliceLivesMatter and #BlueLivesMatter in such a way that historically echoes the tension between Black protesters and law enforcement. In addition, we show that a significant portion of #AllLivesMatter use stems from hijacking by #BlackLivesMatter advocates. Beyond simply injecting #AllLivesMatter with #BlackLivesMatter content, these hijackers use the hashtag to directly confront the counter-protest notion of "All lives matter." Our findings suggest that Black Lives Matter movement was able to grow, exhibit diverse conversations, and avoid derailment on social media by making discussion of counter-protest opinions a central topic of #AllLivesMatter, rather than the movement itself.

Living Well? Strategies Used by Women Living With Metastatic Breast Cancer.

Science.gov (United States)

Lewis, Sophie; Willis, Karen; Yee, Jasmine; Kilbreath, Sharon

2016-07-01

Metastatic breast cancer is a disease of changing status-once an imminent death sentence, now a chronic (albeit incurable) disease. Medical intervention advances mean women with metastatic breast cancer now have symptoms alleviated and, potentially, life extended. Living with this disease, however, requires more than a medical approach to symptoms. We were interested to know whether women manage, and if so, how, to "live well" with metastatic cancer. We conducted interviews with 18 women. Women differed in the approaches they used. Most common was the attempt to reestablish a sense of normality in their lives. However, a second group reevaluated and reprioritized their lives; and a third group was restricted in their capacity to live well because of symptoms. The findings provide the foundation for future research exploring normalization of experiences of metastatic cancer, and other chronic illnesses, where people are living with knowledge that they have contracted time. © The Author(s) 2015.

Diversity, abundance and conservation of birds in an agroecosystem in the Ica desert, Peru

Directory of Open Access Journals (Sweden)

Letty Salinas

2013-05-01

Full Text Available Present work investigates the impact of the agricultural activity in the Peruvian coast on the biodiversity of birds. The study includes the monitoring of birds in asparagus and grapes farms of Ica valley, from January-2004 to January-2006. We evaluated eight types of habitats distributed in a total of 1288 has. Throughout the period of study we registered 93 species of birds. The abundance, richness and diversity were greater in the summers. The greater abundance happened in the habitats of land of asparagus, river brushwood and live fences. The greater richness and diversity happened in January-2006 in alfalfa cultures with huarangos and live fences. The most abundant species were the residents, as Zenaida meloda (6,6 ind./it has, Pygochelidon cyanoleuca (5,9 and the migratory Hirundo rustica (5,9. We registered 12 migratory species. From the conservationist point of view, the number of species catalogued in some degree of threat, at national and international level, is very high. We can emphasize the vulnerable Xenospingus concolor, the Peruvian endemic Colaptes atricollis and the species of desert Geositta peruviana, Sporophila simplex and Burhinus superciliaris. This study demonstrates the importance of agroecosystems in the conservation of the Peruvian Coastal Desert biodiversity, in particular if the enterprise carries out a policy of respect to environment.

Evaluating technology options to mitigate the climate impacts of road transportation can be challenging, particularly when they involve a tradeoff between long-lived emissions (e.g., carbon dioxide) and short-lived emissions (e.g., methane or black carbon). Here we present trends in short- and long-lived emissions for light- and heavy-duty transport globally and in the U.S., EU, and China over the period 2000-2030, and we discuss past and future changes to vehicle technologies to reduce these emissions. We model the tradeoffs between short- and long-lived emission reductions across a range of technology options, life cycle emission intensities, and equivalency metrics. While short-lived vehicle emissions have decreased globally over the past two decades, significant reductions in CO 2 will be required by mid-century to meet climate change mitigation targets. This is true regardless of the time horizon used to compare long- and short-lived emissions. The short-lived emission intensities of some low-CO 2 technologies are higher than others, and thus their suitability for meeting climate targets depends sensitively on the evaluation time horizon. Other technologies offer low intensities of both short-lived emissions and CO 2 .

2014-01-01

Studies aimed at understanding the association between induced abortion and HIV are scarce and differ on the direction of the association. This paper aims to show the prevalence of induced abortion in a sample of pregnancies of women living and not living with HIV/Aids, determining variables associated with pregnancy termination and linked to the life course of women and to the specific context of the pregnancy. Data came from a cross-sectional study, using interviewer-administered questionnaire, developed with women that attended public health services in Porto Alegre, Brazil. A generalized estimating equation model with logit link measured the association between determinants and abortion. The final sample was composed of 684 women living with HIV/Aids (2,039 pregnancies) and 639 women not living with HIV/Aids (1,539 pregnancies). The prevalence of induced abortion among pregnancies in women living with HIV/Aids was 6.5%, while in women not living with HIV/Aids was 2.9%. Among women living with HIV/Aids, the following were associated with induced abortion in the multivariable analysis: being older, having a higher education level, having had more sexual partners (i.e., variables linked to the life course of women), having had children prior to the index pregnancy and living with a sexual partner during pregnancy (i.e., variables linked to the context of each pregnancy). On the other hand, among women not living with HIV/Aids, only having a higher education level and having had more sexual partners (i.e., determinants linked to the life course of women) were associated with voluntary pregnancy termination in multivariable analysis. Although determinants are similar between women living and not living with HIV/Aids, prevalence of induced abortion is higher among pregnancies in women living with HIV/Aids, pointing to their greater social vulnerability and to the need for public policy to address prevention and treatment of HIV associated with reproductive issues.

Direct and indirect effects of petroleum production activities on the western fence lizard (Sceloporus occidentalis) as a surrogate for the dunes sagebrush lizard (Sceloporus arenicolus).

The dunes sagebrush lizard (Sceloporus arenicolus) is a habitat specialist of conservation concern limited to shin oak sand dune systems of New Mexico and Texas (USA). Because much of the dunes sagebrush lizard's habitat occurs in areas of high oil and gas production, there may be direct and indirect effects of these activities. The congeneric Western fence lizard (Sceloporus occidentalis) was used as a surrogate species to determine direct effects of 2 contaminants associated with oil and gas drilling activities in the Permian Basin (NM and TX, USA): herbicide formulations (Krovar and Quest) and hydrogen sulfide gas (H2S). Lizards were exposed to 2 concentrations of H2 S (30 ppm or 90 ppm) and herbicide formulations (1× or 2× label application rate) representing high-end exposure scenarios. Sublethal behavioral endpoints were evaluated, including sprint speed and time to prey detection and capture. Neither H2S nor herbicide formulations caused significant behavioral effects compared to controls. To understand potential indirect effects of oil and gas drilling on the prey base, terrestrial invertebrate biomass and order diversity were quantified at impacted sites to compare with nonimpacted sites. A significant decrease in biomass was found at impacted sites, but no significant effects on diversity. The results suggest little risk from direct toxic effects, but the potential for indirect effects should be further explored. © 2015 SETAC.

Bacterial interference is an alternative strategy to fight against device-associated bacterial infections. Pursuing this strategy, a non-pathogenic bacterial biofilm is used as a live, protective barrier to fence off pathogen colonization. In this work, biofilms formed by probiotic Escherichia coli strain Nissle 1917 (EcN) are investigated for their potential for long-term bacterial interference against infections associated with silicone-based urinary catheters and indwelling catheters used in the digestive system, such as feeding tubes and voice prostheses. We have shown that EcN can form stable biofilms on silicone substrates, particularly those modified with a biphenyl mannoside derivative. These biofilms greatly reduced the colonization by pathogenic Enterococcus faecalis in Lysogeny broth (LB) for 11days. Bacterial interference is an alternative strategy to fight against device-associated bacterial infections. Pursuing this strategy, we use non-pathogenic bacteria to form a biofilm that serves as a live, protective barrier against pathogen colonization. Herein, we report the first use of preformed probiotic E. coli Nissle 1917 biofilms on the mannoside-presenting silicone substrates to prevent pathogen colonization. The biofilms serve as a live, protective barrier to fence off the pathogens, whereas current antimicrobial/antifouling coatings are subjected to gradual coverage by the biomass from the rapidly growing pathogens in a high-nutrient environment. It should be noted that E. coli Nissle 1917 is commercially available and has been used in many clinical trials. We also demonstrated that this probiotic strain performed significantly better than the non-commercial, genetically modified E. coli strain that we previously reported.

Baxter, Jeremy; Baxter, James S.

2002-12-01

This report summarizes the third and final year of a bull trout (Salvelinus confluentus) enumeration project on Skookumchuck Creek in southeastern British Columbia. The fence and traps were operated from September 6th to October 11th 2002 in order to enumerate post-spawning bull trout. During the study period a total of 309 bull trout were captured at the fence. In total, 16 fish of undetermined sex, 114 males and 179 females were processed at the fence. Length and weight data, as well as recapture information, were collected for these fish. An additional 41 bull trout were enumerated upstream of the fence by snorkeling prior to fence removal. Coupled with the fence count, the total bull trout enumerated during the project was 350 individuals. Several fish that were tagged in the lower Bull River were recaptured in 2002, as were repeat and alternate year spawners previously enumerated in past years at the fence. A total of 149 bull trout redds were enumerated on the ground in 2002, of which 143 were in the 3.0 km index section (river km 27.5-30.5) that has been surveyed over the past six years. The results of the three year project are summarized, and population characteristics are discussed.

Using protection motivation theory, we examined racial differences in intent to complete a living will, rational problem solving (e.g., information seeking), and maladaptive coping responses (i.e., wishful thinking) to a health crisis. Sixty healthy, older adults without living wills responded to written vignettes, including information about living wills as an effective coping mechanism to avoid a health crisis. Use of adaptive coping responses predicted intent to execute a living will. A significant race-by-threat interaction predicted use of rational problem solving, with Caucasians more likely to seek information in response to perceived threat in comparison with African Americans. A significant race-by-adaptive-coping interaction predicted maladaptive coping, indicating that Caucasians were more variable in their maladaptive responses. The effectiveness of health care messages regarding living wills for older adults may be enhanced by focusing on racial differences in response to perceived health threat and perceived adaptive coping information.

Solo Living - the meaning of home for persons living alone

DEFF Research Database (Denmark)

Christensen, Toke Haunstrup

observed. Firstly, solo livers emphasize independence from others as important. Several of the informants have had negative experiences with living together with a partner, and they like the feeling of being independent. At the same time, most informants also keep a door open for the possibility of moving...... together with "the right one", which indicates that ambiguity is related to the situation of solo living. Secondly, some of the solo livers spend more time outside home (occupied by leisure activities or together with friends) compared to people living in family households in general, which suggests...... a different balance between time at home and outside home for some solo livers....

New mixed crystals, Fe(NCS) x (NCBH 3 )( 2-x )(bpp) 2 , (bpp = 1,3-bis(4-pyridyl)propane) were synthesized. The formation of mixed crystals was confirmed by powder X-ray diffraction patterns and single crystal X-ray structural analysis. Elemental analyses showed that all Fe(NCS) x (NCBH 3 )( 2-x )(bpp) 2 samples had more Fe(NCS) 2 unit than the preparation fraction. 57 Fe Moessbauer spectroscopy revealed that all the spectra consist of only Fe(NCS) 2 unit and Fe(NCBH 3 ) 2 unit. And the fraction of low-spin state in the Fe(NCBH 3 ) 2 unit changed with the change of x. The results suggested that the high spin site of Fe(NCS) 2 unit affects the spin state of Fe(NCBH 3 ) 2 unit. (author)

The lived experiences of children living on the streets of Hillbrow

Directory of Open Access Journals (Sweden)

Chris Myburgh

2015-05-01

Full Text Available Background: The effects of daily abuse and hardship on the streets lead to poor mental health in children living on the streets, resulting in them choosing ineffective and self-destructive coping strategies that impact their physical health and overall sense of wellbeing. The facilitation of the mental health of children living on the streets who are subjected to daily threats to their survival is thus crucial. Objectives: The aim of this research was to explore and describe the lived experiences of children living on the streets of Hillbrow, Johannesburg. Method: The research design was qualitative, exploratory, descriptive and contextual. A purposive sample was selected through a temporary shelter in Johannesburg, Gauteng, South Africa and consisted of 14 male children living on the streets. Data were collected using drawings, in-depth phenomenological interviews and field notes. The central interview opening statement was: ‘Tell me about your life on the street’. Results: The results obtained indicated that children living on the streets are threatened, exploited and exposed to physical, sexual and emotional abuse on a daily basis by the community, the authorities and other street dwellers. This leads to feelings of sadness, fear, anxiety, misery, despair, hopelessness, helplessness and suicide ideation, which in turn lead to drug abuse and criminal activities. In contrast, positive feelings of sympathy for other children living on the streets emerged and these children also displayed perseverance, resilience and a striving for autonomy. Conclusion: Street life exposes children to a variety of experiences, both positive and negative. A striving after autonomy is clearly depicted by these children, who are able to tap into a range of responses, both on- and off-street.

It was intended to confirm, based on various problems surrounding oil flow-out accidents, that oil fences whose use is first considered when an oil flow-out accident occurs cause oil leakage due to oil pass-through phenomenon as the largest defect in performance of oil fences. Therefore, oil fence performance was analyzed by using a simulation. Furthermore, several types of diffusion prevention and avoidance measures, and combinations thereof were evaluated by using multi-criteria analysis. It was also elucidated how recognitions on the importance of methods to prevent oil pollution differ depending on standpoints. Difference in oil flow-out prevention performance of oil fences due to variation in tidal currents was made clear by combining a diffusion simulation using the finite element method with the prevention performance of oil fences relative to the tidal currents. In areas with no good hydrographic conditions where pollution spreads rapidly, it is necessary to suppress oil diffusion by extending oil fences double or triple, and using gelling agents. 4 refs., 8 figs.

Many long-lived avian species adopt life strategies that involve a gregarious way of life at juvenile and sub-adult stages and territoriality during adulthood. However, the potential associated costs of these life styles, such as stress, are poorly understood. We examined the effects of group living, sex and parasite load on the baseline concentration of faecal stress hormone (corticosterone) metabolites in a wild population of common ravens (Corvus corax). Corticosterone concentrations were significantly higher in non-breeding gregarious ravens than in territorial adults. Among territorial birds, males showed higher stress levels than their mates. Parasite burdens did not affect hormone levels. Our results suggest a key role of the social context in the stress profiles of the two population fractions, and that group living may be more energetically demanding than maintaining a territory. These findings have implications for understanding hormonal mechanisms under different life styles and may inspire further research on the link between hormone levels and selective pressures modulating gregarious and territorial strategies in long-lived birds.

Recent changes to United States law now permit people living with HIV (PLWH) to donate organs to HIV-infected (HIV+) recipients under research protocols. PLWH may have unique motivations for and concerns about living donation and understanding them is critical to ensuring the integrity of this novel approach to organ transplantation. We conducted in-depth interviews with PLWH from an urban HIV clinic who had previously indicated their willingness to be a living donor. Interviews elicited information on their motivations, perceived benefits, and concerns regarding living donation. Codes were identified inductively and then organized into themes and subthemes. Two coders independently analyzed the interviews and reconciled differences in coding by consensus. Thematic saturation was reached after 20 interviews. Motivations for living donation among PLWH included an altruistic desire to help others as well as HIV-specific motivations including solidarity with potential recipients and a desire to overcome HIV-related stigma. Perceived benefits of living donation included gratification from saving or improving the recipient's life and conferring a sense of normalcy for the HIV+ donor. Concerns about donation included the possibility of a prolonged recovery period, organ failure, and transmission of another strain of the virus to the recipients. PLWH had unique motivations, perceived benefits, and concerns about living donation in addition to those previously identified in the general population. These unique factors should be addressed in research protocols, informed consent processes, and the education and training of independent living donor advocates so that these endeavors are ethically sound.

We have measured the half-lives of short-lived isotopes for past decade and deduced the half-lives of 6 isotopes further. These results demonstrated that most of the literature values shorter than 10 min systematically deviated from our measurement ones. The cause seems to be that a large number of the previous half-life studies were performed with scintillation counters before 1970 and they had a difficulty in distinguishing the interest {gamma}-ray from the contamination and correcting for pile-up and dead-time losses. Moreover, the deviated data found to be quoted for evaluation. (author)

2015-09-01

Full Text Available This paper deals with the evaluation of selected available indicators of living standards, divided into three groups, namely economic, environmental, and social. We have selected six countries of the European Union for analysis: Bulgaria, the Czech Republic, Hungary, Luxembourg, France, and Great Britain. The aim of this paper is to evaluate indicators measuring living standards and suggest the most important factors which should be included in the final measurement. We have tried to determine what factors influence each indicator and what factors affect living standards. We have chosen regression analysis as our main method. From the study of factors, we can deduce their impact on living standards, and thus the value of indicators of living standards. Indicators with a high degree of reliability include the following factors: size and density of population, health care and spending on education. Emissions of carbon dioxide in the atmosphere also have a certain lower degree of reliability.

Spent fuel storage pool

International Nuclear Information System (INIS)

Murakami, Naoshi.

1996-01-01

Fences are disposed to a fuel exchange floor surrounding the upper surface of a fuel pool for preventing overflow of pool water. The fences comprise a plurality of flat boards arranged in parallel with each other in the longitudinal direction while being vertically inclined, and slits are disposed between the boards for looking down the pool. Further, the fences comprise wide boards and are constituted so as to be laid horizontally on the fuel exchange floor in a normal state and uprisen by means of the signals from an earthquake sensing device. Even if pool water is overflow from the fuel pool by the vibrations occurred upon earthquake and flown out to the floor of the fuel exchange floor, the overflow from the fuel exchange floor is prevented by the fences. An operator who monitors the fuel pool can observe the inside of the fuel pool through the slits formed to the fences during normal operation. The fences act as resistance against overflowing water upon occurrence of an earthquake thereby capable of reducing the overflowing amount of water due to the vibrations of pool water. The effect of preventing overflowing water can be enhanced. (N.H.)

How we live and why we die the secret lives of cells

Wolpert, Lewis

2009-01-01

Cells are the basis of all life in the universe. Our bodies are made up of billions of them: an incredibly complex society that governs everything, from movement to memory and imagination. When we age, it is because our cells slow down; when we get ill, it is because our cells mutate or stop working. In "How We Live and Why we Die", Wolpert provides a clear explanation of the science that underpins our lives. He explains how our bodies function and how we derived from a single cell - the embryo. He examines the science behind the topics that are much discussed but rarely understood - stem-cell research, cloning, DNA - and explains how all life evolved from just one cell. Lively and passionate, "How We Live and Why we Die" is an accessible guide to understanding the human body and, essentially, life itself.

"Of those young people living independently (not in their parental homes), how do incomes from various sources affect their decision whether to live alone or with others? The sample did not include all persons in the 15-24 age group, only those living independently. A logit analysis of the living alone question was conducted using data from five countries (Canada, the Federal Republic of Germany, the United Kingdom, Australia, and the United States) included in the LIS [Luxembourg Income Study] data base to determine whether differences across countries exist." excerpt

Unraveling the Relative Importance of Oral and Dermal Contaminant Exposure in Reptiles: Insights from Studies Using the Western Fence Lizard (Sceloporus occidentalis)

Weir, Scott M.; Talent, Larry G.; Anderson, Todd A.; Salice, Christopher J.

2014-01-01

Despite widespread recognition of significant data deficiencies, reptiles remain a relatively understudied taxon in ecotoxicology. To conduct ecological risk assessments on reptiles frequently requires using surrogate taxa such as birds, but recent research suggests that reptiles have significantly different exposure profiles and toxicant sensitivity. We exposed western fence lizards, Sceloporus occidentalis, to the same quantities of three model chemicals via oral (gavage) and dermal (ventral skin application) exposure for either 24 or 48 hours. Three phthalate esters (di-methyl phthalate [DMP], di-iso-butyl phthalate [DIBP], and di-n-octyl phthalate [DNOP]) were chosen as model chemicals because they represent a gradient of lipophilicity but are otherwise structurally similar. Overall, the more lipophilic phthalates (DIBP and DNOP) were found to have higher concentrations in tissues than the less lipophilic DMP. Significant differences in tissue concentrations between DIBP and DNOP were tissue-dependent, suggesting that delivery to a site of action following exposure is not only a simple function of lipophilicity. In dermal treatments, DMP usually had fewer detections (except in ventral skin samples), suggesting that lipophilicity (log Kow>2) is a requirement for uptake across the skin. In general, tissue residues were greater in oral treatments than dermal treatments (significant in adipose and liver tissue), but differences were driven strongly by differences in DMP which did not appear to be absorbed well across skin. When differences in tissue residue concentrations between oral and dermal exposure did occur, the difference was not drastic. Taken together these results suggest that dermal exposure should be considered in risk assessments for reptilian receptors. Dermal exposure may be an especially important route for reptiles as their ectothermic physiology translates to lower energetic demands and dietary exposure compared to birds and mammals. PMID

2017-11-20

To examine perceived control among live-in and live-out home care workers and to identify factors that contribute to perceived control among both types of caregiving. 338 migrant live-in home care workers and 185 local live-out home care workers were asked to report their perceived control. Burnout, satisfaction with the relationship with the care recipient and the care recipient's family, and satisfaction with social relationship were also gathered. Both types of caregivers reported high levels of perceived control, although live-in home care workers expressed more perceived control. Higher age, higher levels of satisfaction with the relationship with the care recipient and the care recipient's family and lower levels of burnout, predicted perceived control. Satisfaction with social relationship was a stronger predictor of one's perceived control among live-in home care workers. Promoting social relationships outside the home care context by allowing migrant live-in home care workers to take part in social gatherings is recommended as this can strengthen their sense of perceived control.

2014-01-20

Polyhomologation, recently developed by Shea, is a borane-initiated living polymerization of ylides leading to linear polymethylenes (C1 polymerization) with controlled molecular weight, low polydispersity, and well-defined structures. In this Review, the copolyhomologation of different ylides as well as the combination of polyhomologation with controlled/living (nitroxide-mediated, atom transfer radical, reversible addition-fragmentation chain-transfer) and living (ring opening, anionic) polymerizations is discussed. Polyhomologation of ylides, in combination with living and controlled/living polymerizations, leads to a plethora novel well-defined polymethylene (polyethylene)-based polymeric materials, which are very important for understanding/improving the behavior of industrial polyethylenes. © 2014 WILEY-VCH Verlag GmbH & Co.

In both systems the soil flows were higher in the rainy season (1.1 mol CO2 m2 h-1 on average and slightly lower in the dry season (0.90 mol CO2 m2 h-1 on average and were higher during the night (00:00 to 06:00 hours, during the early morning hours (6:00 to 12:00 hours. Soil temperature was higher in the MP, and the relative humidity in LF. It is concluded that the main factor that caused the variation in soil respiration rates was the presence of G. sepium trees in LF, which led to lower temperatures and more stable humidity, which resulted in lower soil CO2 fluxes.

The purpose of psychotherapy is to help clients address and overcome problems troubling them in their everyday lives. Therapy can therefore only work if clients include it in their ongoing lives to deal with their problems. Detailed, systematic research is needed on how clients do so...... clients change their everyday lives to overcome their troubles. They also highlight what it involves for clients to accomplish this. It is concluded that we need more research on how to understand intervention; on the interaction between interventions and clients’ conduct of their everyday life...

We examined the meaning of living with HIV/AIDS among women in Lebanon. Ten women living with HIV/AIDS (WLWHA) described their experiences via semistructured in-depth interviews. They navigated a process of HIV diagnosis acceptance that incorporated six overlapping elements: receiving the news, accessing care, starting treatment, navigating disclosure decisions, negotiating stigma, and maintaining stability. Through these elements, we provide a framework for understanding three major themes that were constructed during data analysis: Stand by my side: Decisions of disclosure; Being “sick” and feeling “normal”: Interacting with self, others, and society; and Living day by day: focusing on the present. We contribute to the existing literature by providing a theoretical framework for understanding the process of diagnosis and sero-status acceptance among WLWHA. This was the first study of its kind to examine the meaning of living with HIV/AIDS among women in a Middle Eastern country. PMID:28462340

As the global population of older people continuously increases, many countries are beginning to experience health problems associated with older age. These countries may be interested in knowing and understanding the health problems experienced by the older Korean population, which is projected to age the most rapidly. This study aimed to compare and examine the factors that influence the life satisfaction between older people living with their family and those living alone. A cross-sectional survey was conducted. The participants comprised a total 300 older Koreans (150 living with their family, 150 living alone) aged 65 years or over who met the eligibility criteria. All measures were self-administered. Data were analysed using the SAS statistical software program version 6.12 (SAS Institute Inc., Cary, NC). The older people living with their family were better than the older people living alone in perceived health status, self-esteem, depression and life satisfaction. Perceived health status, self-esteem, depression, age and monthly allowance were found to be the factors related to the life satisfaction of older people living with their family and those living alone. The factors that were found to have the greatest influence on the life satisfaction of older people living with their family and those living alone were depression and perceived health, respectively. This study may help healthcare providers to understand the factors that can influence the life satisfaction among older people living with their family and living alone in Korea. © 2011 The Authors.

Joutsenniemi, Kaisla; Martelin, Tuija; Martikainen, Pekka; Pirkola, Sami; Koskinen, Seppo

2006-01-01

Background Non‐married persons are known to have poor mental health compared with married persons. Health differences between marital status groups may largely arise from corresponding differences in interpersonal social bonds. However, official marital status mirrors the social reality of persons to a decreasing extent, and living arrangements may be a better measure of social bonds. Little is known about mental health in different living arrangement groups. This study aims to establish the extent and determinants of mental health differences by living arrangement in terms of psychological distress (GHQ) and DSM‐IV psychiatric disorders (CIDI). Methods Data were used from the nationally representative cross sectional health 2000 survey, conducted in 2000–1 in Finland. Altogether 4685 participants (80%) aged 30–64 years were included in these analyses; comprehensive information was available on measures of mental health and living arrangements. Living arrangements were measured as follows: married, cohabiting, living with other(s) than a partner, and living alone. Results Compared with the married, persons living alone and those living with other(s) than a partner were approximately twice as likely to have anxiety or depressive disorders. Cohabiters did not differ from the married. In men, psychological distress was similarly associated with living arrangements. Unemployment, lack of social support, and alcohol consumption attenuated the excess psychological distress and psychiatric morbidity of persons living alone and of those living with other(s) than a partner by about 10%–50% each. Conclusions Living arrangements are strongly associated with mental health, particularly among men. Information on living arrangements, social support, unemployment, and alcohol use may facilitate early stage recognition of poor mental health in primary health care. PMID:16698975

McDonald, Penelope W; Dickerson, Suzanne

2013-12-01

The purpose of this study was to determine the common meanings a history of violence has for women out of abusive and violent relationships with an intimate male partner for 5 or more years. To describe the common meanings and shared practices of women who left violent and abusive heterosexual intimate relationships 5 or more years ago, the challenges they face in their current lives, and the resources they use to meet those challenges. An additional aim is to elucidate practical advice they have for others who want to be supportive of the efforts of women recovering from intimate partner violence. An interpretive phenomenological approach using Heideggerian hermeneutics was utilized. Approval of the University Social Sciences Institutional Review Board was obtained. Participants were recruited by means of fliers distributed through a domestic violence listserv and through postings in health clinics in western New York. Interviews were recorded and transcribed. A hermeneutic team approach was used for analysis and interpretation of texts. Twenty-one women of various ages, ethnicities, and backgrounds, who self-identified as being out of abusive relationships for 5 or more years, were interviewed. Six themes were identified: developing and maintaining self reliance; negotiating relationships; creating a safe and supportive environment; challenging societal roles and expectations; nurturing the self; and protecting the children. Engendering independence while living with purpose was the constitutive pattern that unified the themes. Women can successfully establish productive, meaningful lives after violence and will fiercely protect and maintain their independence as they negotiate relationships and developmental challenges throughout their lives. A need for control of their lives and difficulty trusting others remain a lasting legacy of living with a history of violence. This is the first study that examines women's lives 5 or more years after leaving violent and

[Passive euthanasia and living will].

Science.gov (United States)

Julesz, Máté

2014-07-06

This article deals with the intentional distinction between murder of first degree and passive euthanasia. In Hungary, active euthanasia is considered to be a murder of first degree, whilst the Netherlands, Belgium, Luxemburg and Switzerland have legalized the active form of mercy killing in Europe. The palliative terminal care, when e.g. giving pain-killer morphine to the patient, might result in decreasing the patient's life-span, and thus causing indirect euthanasia. However, the legal institution of living will exists in several counter-euthanasia countries. The living will allows future patients to express their decision in advance to refuse a life-sustaining treatment, e.g. in case of irreversible coma. The institution of living will exists in Germany and in Hungary too. Nevertheless, the formal criteria of living will make it hardly applicable. The patient ought to express his/her will before a notary public in advance, and he/she should hand it over when being hospitalized. If the patient is not able to present his/her living will to his/her doctor in the hospital, then his/her only hope remains that he/she has given a copy of the living will to the family doctor previously, and the family doctor will notify the hospital.

Ayalon, Liat; Green, Ohad

2015-08-01

The present study provides a preliminary examination of the relationship between the type of home care services (live-in vs. live-out; i.e., round the clock vs. several hours per week), the caregiver's satisfaction with services, and the caregiver's burden, distress, well-being, and subjective health status within the conceptual framework of caregiving outcomes proposed by Yates and colleagues (Yates, M. E., Tennstedt, S., & Chang, B. H. [1999]. Contributors to and mediators of psychological well-being for informal caregivers. Journal of Gerontology: Psychological Sciences, 54, P12 -P22. doi:10.1093/geronb/54B.1.P12). A random stratified sample of family caregivers of older adults more than the age of 70 who receive live-in (442) or live-out (244) home care services through the financial assistance of the National Insurance institute of Israel was selected. A path analysis was conducted. Satisfaction with services was higher among caregivers under the live-in home care arrangement and positively related to well-being. Among caregivers, live-in home care was directly associated with higher levels of subjective health and indirectly associated with better well-being via satisfaction with services. The present study emphasizes the potential benefits of live-in home care services for caregivers of older adults who suffer from high levels of impairment and the importance of assessing satisfaction with services as a predictor of caregivers' outcomes. © The Author 2013.

2015-09-01

Solid organ transplantation as a treatment for end stage organ failure has been an accepted treatment option for decades. Despite advances in medicine and technology, and increased awareness of organ donation and transplantation, the gap between supply and demand continues to widen. Living donation has been an option that has increased the number of transplants despite the continued shortage of deceased organs. In the early 2000s live donor transplantation reached an all-time high in the United States. As a result, a consensus meeting was convened in 2000 to increase the oversight of living donor transplantation. Both the Centers for Medicare and Medicaid Services and the United Network for Organ Sharing developed regulations that transplant programs performing live donor transplantation. These regulations and guidelines involve the education, evaluation, informed consent process and living donor follow-up care. Two areas in which had significant changes included the psychosocial and the independent living donor advocate (ILDA) evaluation. The purpose of this paper was to outline the current regulations and guidelines associated with the psychosocial and ILDA evaluation as well as provide further recommendations for the administration of a high quality evaluation of living donors. The goals and timing of the evaluation and education of donors; qualifications of the health care providers performing the evaluation; components of the evaluation; education provided to donors; documentation of the evaluation; participation in the selection committee meeting; post-decline and post-donation care of donors is described. Caveats including the paired donor exchange programs and non-directed and directed donation are also considered.

Live-cell imaging.

Cole, Richard

2014-01-01

It would be hard to argue that live-cell imaging has not changed our view of biology. The past 10 years have seen an explosion of interest in imaging cellular processes, down to the molecular level. There are now many advanced techniques being applied to live cell imaging. However, cellular health is often under appreciated. For many researchers, if the cell at the end of the experiment has not gone into apoptosis or is blebbed beyond recognition, than all is well. This is simply incorrect. There are many factors that need to be considered when performing live-cell imaging in order to maintain cellular health such as: imaging modality, media, temperature, humidity, PH, osmolality, and photon dose. The wavelength of illuminating light, and the total photon dose that the cells are exposed to, comprise two of the most important and controllable parameters of live-cell imaging. The lowest photon dose that achieves a measureable metric for the experimental question should be used, not the dose that produces cover photo quality images. This is paramount to ensure that the cellular processes being investigated are in their in vitro state and not shifted to an alternate pathway due to environmental stress. The timing of the mitosis is an ideal canary in the gold mine, in that any stress induced from the imaging will result in the increased length of mitosis, thus providing a control model for the current imagining conditions.

On harm thresholds and living organ donation: must the living donor benefit, on balance, from his donation?

Science.gov (United States)

Williams, Nicola Jane

2018-03-01

For the majority of scholars concerned with the ethics of living organ donation, inflicting moderate harms on competent volunteers in order to save the lives or increase the life chances of others is held to be justifiable provided certain conditions are met. These conditions tend to include one, or more commonly, some combination of the following: (1) The living donor provides valid consent to donation. (2) Living donation produces an overall positive balance of harm-benefit for donors and recipients which cannot be obtained in a less harmful manner. (3) Donation is not liable to cause significant and long-term morbidity to, or the death of, the donor. This paper critically examines the suggestion that these criteria are not sufficient to offer a general account of justified living organ donation in the context of competent volunteers and that key to justified living organ donation is that donors receive sufficient benefits from their donation that these outweigh the harms they suffer. However, although this view-termed here 'The Donor Benefit Standard'-directs welcome attention to the many and complex motives which may underlie living organ donation, this paper ultimately concludes that given the threats this position poses to individual autonomy and the lives of those in need of organ transplants 'The Donor Benefit Standard' should ultimately be rejected.

"On the Fence" versus "All in": Insights from Turtles for the Evolution of Aquatic Locomotor Specializations and Habitat Transitions in Tetrapod Vertebrates.

Science.gov (United States)

Blob, Richard W; Mayerl, Christopher J; Rivera, Angela R V; Rivera, Gabriel; Young, Vanessa K H

2016-12-01

Though ultimately descended from terrestrial amniotes, turtles have deep roots as an aquatic lineage and are quite diverse in the extent of their aquatic specializations. Many taxa can be viewed as "on the fence" between aquatic and terrestrial realms, whereas others have independently hyperspecialized and moved "all in" to aquatic habitats. Such differences in specialization are reflected strongly in the locomotor system. We have conducted several studies to evaluate the performance consequences of such variation in design, as well as the mechanisms through which specialization for aquatic locomotion is facilitated in turtles. One path to aquatic hyperspecialization has involved the evolutionary transformation of the forelimbs from rowing, tubular limbs with distal paddles into flapping, flattened flippers, as in sea turtles. Prior to the advent of any hydrodynamic advantages, the evolution of such flippers may have been enabled by a reduction in twisting loads on proximal limb bones that accompanied swimming in rowing ancestors, facilitating a shift from tubular to flattened limbs. Moreover, the control of flapping movements appears related primarily to shifts in the activity of a single forelimb muscle, the deltoid. Despite some performance advantages, flapping may entail a locomotor cost in terms of decreased locomotor stability. However, other morphological specializations among rowing species may enhance swimming stability. For example, among highly aquatic pleurodiran turtles, fusion of the pelvis to the shell appears to dramatically reduce motions of the pelvis compared to freshwater cryptodiran species. This could contribute to advantageous increases in aquatic stability among predominantly aquatic pleurodires. Thus, even within the potential constraints of a body plan in which the body is encased by a shell, turtles exhibit diverse locomotor capacities that have enabled diversification into a wide range of aquatic habitats. © The Author 2016.

'Living between two worlds': who is living in whose worlds?

Science.gov (United States)

McCoy, Brian

2009-08-01

Indigenous people have often been depicted as 'living between two worlds'. They have been described as living neither in their 'Indigenous' world nor in the 'Western' world but in some middle, liminal, or in-between 'world'. People in such situations are often described as 'caught' or 'suspended' and with obvious negative social, emotional and health consequences. What is this cultural space that is often described as 'being between two worlds'? Can Indigenous people develop their identity within the demands and values of contemporary Australian society? Most people who live within the context of modernity move across a mixture of different social, spiritual and cultural 'worlds'. By projecting particular and negative meanings onto Indigenous people and their journey of identity, non-Indigenous people diminish the value of Indigenous energies and initiatives in attempting to cope with life's diverse pressures and expectations. The perpetuation of such attitudes serves to undermine the efforts that Indigenous people make to engage modernity while at the same time attempting to maintain values that are of critical importance for their health and wellbeing. Consequently, non-Indigenous people can end up diminishing the importance of their own life transitions.

Gross theory of beta-decay and half-lives of short-lived nuclei

Yamada, Masami; Kondo, Norikatsu.

1976-01-01

The gross theory of beta-decay has been developed, and this theory offers the means of calculating directly the function of beta-decay intensity, then half-lives, complex beta spectra and so on are estimated from it. This paper presents the more refined theory by introducing the shell effect. The shell effect is considered in the intensity function. The half-lives in the electron decay of In with spin of 9/2 + , the positron decay of Bi, Po, At and Rn, and the decay of odd-odd nuclei were estimated. The introduction of the shell effect shows better agreement between the theory and the experimental data. The inequality relations of intensity functions and half-lives of two adjacent nuclei were obtained. When the spins and parities of two nuclei are same, the inequality relations hold especially good.

Full Text Available Comparative research suggests that there are great cross-national and cross-temporal differences in living arrangements of young adults aged 18-34 in Europe. In this paper, we examine young adults’ living arrangements (1 across several European countries and different national contexts, and (2 by taking into account cross-time variability. In doing so, we pay careful attention to a comprehensive conceptualisation of living arrangements (including extended and non-family living arrangements. The aim of this paper is to deepen our understanding of family structure and household arrangements in Europe by examining and mapping the cross-national and cross-temporal variety of young adults’ living arrangements. For our analysis we use data from the Integrated Public Use Microdata Series International (IPUMSi for the census rounds 1980, 1990, and 2000 for eight European countries (Austria, France, Greece, Hungary, Ireland, Portugal, Romania, and Switzerland. We employ log-linear models to ascertain the influence of individual and contextual factors on living arrangements. The analyses lend further support to a North/West – South/East divide in living arrangements and general gender differentials in extended family living. Other interesting results are the heterogeneity in the living arrangements of single mothers across geographic areas, and the upward trend of extended household living for young men and women between 1980 and 2000.

Living Together v. Living Well Together: A Normative Examination of the SAS Case

Directory of Open Access Journals (Sweden)

Lori G. Beaman

2016-04-01

Full Text Available The European Court of Human Rights decision in SAS from France illustrates how a policy and national mantra that ostensibly aims to enhance inclusiveness, ‘living together’, is legally deployed in a manner that may have the opposite effect. In essence, despite acknowledging the sincerity of SAS’s religious practice of wearing the niqab, and her agency in making the decision to do so, the Court focuses on radicalism and women’s oppression amongst Muslims. Taking the notion of living together as the beginning point, the paper explores the normative assumptions underlying this notion as illustrated in the judgment of the Court. An alternative approach, drawing on the work of Derrida for the notion of ‘living well together’ will be proposed and its implications for social inclusion explicated. The paper’s aim is to move beyond the specific example of SAS and France to argue that the SAS pattern of identifying particular values as ‘national values’, the deployment of those values through law, policy and public discourse, and their exclusionary effects is playing out in a number of Western democracies, including Canada, the country with which the author is most familiar. Because of this widespread dissemination of values and their framing as representative of who ‘we’ are, there is a pressing need to consider the potentially alienating effects of a specific manifestation of ‘living together’ and an alternative model of ‘living well together’.

Living Systems Energy Module

1995-09-26

The Living Systems Energy Module, renamed Voyage from the Sun, is a twenty-lesson curriculum designed to introduce students to the major ways in which energy is important in living systems. Voyage from the Sun tells the story of energy, describing its solar origins, how it is incorporated into living terrestrial systems through photosynthesis, how it flows from plants to herbivorous animals, and from herbivores to carnivores. A significant part of the unit is devoted to examining how humans use energy, and how human impact on natural habitats affects ecosystems. As students proceed through the unit, they read chapters of Voyage from the Sun, a comic book that describes the flow of energy in story form (Appendix A). During the course of the unit, an ``Energy Pyramid`` is erected in the classroom. This three-dimensional structure serves as a classroom exhibit, reminding students daily of the importance of energy and of the fragile nature of our living planet. Interactive activities teach students about adaptations that allow plants and animals to acquire, to use and to conserve energy. A complete list of curricular materials and copies of all activity sheets appear in Appendix B.

Optical Remote Sensing for Fence-Line Monitoring using Open-Path Quantum Cascade Laser (QCL) mono-static system for multiple target compounds in the Mid IR 7-13um (Fingerprint) region.

Science.gov (United States)

Zemek, P. G.

2017-12-01

Quantum Cascade Lasers (QCLs) are quickly replacing Tunable Diode Lasers (TDL) for multi-target species identification and quantification in both extractive and open-path (OP) Optical Remote Sensing (ORS) fence-line instrumentation. As was seen with TDL incorporation and pricing drops as the adoption by the telecommunications industry and its current scaling has improved robustness and pricing, the QCL is also, albiet more slowly, becoming a mature market. There are several advantages of QCLs over conventional TDLs such as improved brightness and beam density, high resolution, as well as the incorporation of external etalons or internal gratings to scan over wide spectral areas. QCLs typically operate in the Mid infra-red (MIR) as opposed to the Near-Infrared (NIR) region used with TDL. The MidIR is a target rich absorption band area where compounds have high absorbtivity coefficients resulting in better detection limits as compared to TDL instruments. The use of novel chemometrics and more sensitive non-cryo-cooled detectors has allowed some of the first QCL open-path instruments in both active and passive operation. Data and field studies of one of the newest QCL OP systems is presented that allows one system to measure multiple target compounds. Multiple QCL spectral regions may be stitched together to increase the capability of QCLs over TDL OP systems. A comparison of several ORS type systems will be presented.

Bedau, Mark A; McCaskill, John S; Packard, Norman H; Rasmussen, Steen

2010-01-01

The concept of living technology-that is, technology that is based on the powerful core features of life-is explained and illustrated with examples from artificial life software, reconfigurable and evolvable hardware, autonomously self-reproducing robots, chemical protocells, and hybrid electronic-chemical systems. We define primary (secondary) living technology according as key material components and core systems are not (are) derived from living organisms. Primary living technology is currently emerging, distinctive, and potentially powerful, motivating this review. We trace living technology's connections with artificial life (soft, hard, and wet), synthetic biology (top-down and bottom-up), and the convergence of nano-, bio-, information, and cognitive (NBIC) technologies. We end with a brief look at the social and ethical questions generated by the prospect of living technology.

Traditional cattle grazing in a mosaic alkali landscape: effects on grassland biodiversity along a moisture gradient.

Directory of Open Access Journals (Sweden)

Péter Török

Full Text Available Extensively managed pastures are of crucial importance in sustaining biodiversity both in local- and landscape-level. Thus, re-introduction of traditional grazing management is a crucial issue in grassland conservation actions worldwide. Traditional grazing with robust cattle breeds in low stocking rates is considered to be especially useful to mimic natural grazing regimes, but well documented case-studies are surprisingly rare on this topic. Our goal was to evaluate the effectiveness of traditional Hungarian Grey cattle grazing as a conservation action in a mosaic alkali landscape. We asked the following questions: (i How does cattle grazing affect species composition and diversity of the grasslands? (ii What are the effects of grazing on short-lived and perennial noxious species? (iii Are there distinct effects of grazing in dry-, mesophilous- and wet grassland types? Vegetation of fenced and grazed plots in a 200-ha sized habitat complex (secondary dry grasslands and pristine mesophilous- and wet alkali grasslands was sampled from 2006-2009 in East-Hungary. We found higher diversity scores in grazed plots compared to fenced ones in mesophilous- and wet grasslands. Higher cover of noxious species was typical in fenced plots compared to their grazed counterparts in the last year in every studied grassland type. We found an increasing effect of grazing from the dry- towards the wet grassland types. The year-to-year differences also followed similar pattern: the site-dependent effects were the lowest in the dry grassland and an increasing effect was detected along the moisture gradient. We found that extensive Hungarian Grey cattle grazing is an effective tool to suppress noxious species and to create a mosaic vegetation structure, which enables to maintain high species richness in the landscape. Hungarian Grey cattle can feed in open habitats along long moisture gradient, thus in highly mosaic landscapes this breed can be the most suitable

Designing Viable Business Models for Living Labs

Directory of Open Access Journals (Sweden)

Bernhard R. Katzy

2012-09-01

Full Text Available Over 300 regions have integrated the concept of living labs into their economic development strategy since 2006, when the former Finnish Prime Minister Esko Aho launched the living lab innovation policy initiative during his term of European presidency. Despite motivating initial results, however, success cases of turning research into usable new products and services remain few and uncertainty remains on what living labs actually do and contribute. This practitioner-oriented article presents a business excellence model that shows processes of idea creation and team mobilization, new product development, user involvement, and entrepreneurship through which living labs deliver high-potential investment opportunities. Customers of living labs are identified as investors such as venture capitalists or industrial firms because living labs can generate revenue from them to create their own sustainable business model. The article concludes that living labs provide extensive support “lab” infrastructure and that it remains a formidable challenge to finance it, which calls for a more intensive debate.

The global need for lived experience leadership.

Byrne, Louise; Stratford, Anthony; Davidson, Larry

Common challenges and experiences of the lived experience/peer workforce globally are considered, with an emphasis on ensuring that future developments both protect and promote the unique lived experience perspective. In the Western world, rapid growth in lived experience roles has led to an urgent need for training and workforce development. However, research indicates the roles risk being coopted without clear lived experience leadership, which is often not occurring. In developing countries and in many Western contexts, the lived experience role has not yet been accepted within the mental health workforce. The need for lived experience leadership to guide these issues is highlighted. Peer-reviewed research, relevant gray literature, and professional experience in countries where little published material currently exists. A window of opportunity currently exists to maximize lived experience leadership, and that window may be closing fast if broad-based actions are not initiated now.

During 2000, 3 new projects were completed thereby adding 4.6 miles of stream to the program. Protection for these reaches required the construction of 3.2 miles of riparian fence and 1 livestock watering sites. 5,750 pounds of grass and shrub seed were planted for revegetating ground disturbed during construction. Stream temperatures were monitored on the Middle Fork of the John Day. All project fences, watergaps, spring developments and plantings were checked and repairs performed where needed. We now have 70 miles of stream protected using 111 miles of fence.

Linde, Ana Rosa; Siqueira, Carlos Eduardo

2018-05-10

Zika virus infection during pregnancy is a cause of congenital brain abnormalities. Its consequences to pregnancies has made governments, national and international agencies issue advices and recommendations to women. There is a clear need to investigate how the Zika outbreak affects the decisions that women take concerning their lives and the life of their families, as well as how women are psychologically and emotionally dealing with the outbreak. We conducted a qualitative study to address the impact of the Zika epidemic on the family life of women living in Brazil, Puerto Rico, and the US, who were affected by it to shed light on the social repercussions of Zika. Women were recruited through the snowball sampling technique and data was collected through semi-structured interviews. We describe the effects in mental health and the coping strategies that women use to deal with the Zika epidemic. Zika is taking a heavy toll on women's emotional well-being. They are coping with feelings of fear, helplessness, and uncertainty by taking drastic precautions to avoid infection that affect all areas of their lives. Coping strategies pose obstacles in professional life, lead to social isolation, including from family and partner, and threaten the emotional and physical well-being of women. Our findings suggest that the impacts of the Zika epidemic on women may be universal and global. Zika infection is a silent and heavy burden on women's shoulders.

Kaplan, Rachel L; Khoury, Cynthia El; Field, Emily R S; Mokhbat, Jacques

2016-01-01

We examined the meaning of living with HIV/AIDS among women in Lebanon. Ten women living with HIV/AIDS (WLWHA) described their experiences via semistructured in-depth interviews. They navigated a process of HIV diagnosis acceptance that incorporated six overlapping elements: receiving the news, accessing care, starting treatment, navigating disclosure decisions, negotiating stigma, and maintaining stability. Through these elements, we provide a framework for understanding three major themes that were constructed during data analysis: Stand by my side: Decisions of disclosure; Being "sick" and feeling "normal": Interacting with self, others, and society; and Living day by day: focusing on the present. We contribute to the existing literature by providing a theoretical framework for understanding the process of diagnosis and sero-status acceptance among WLWHA. This was the first study of its kind to examine the meaning of living with HIV/AIDS among women in a Middle Eastern country.

Full Text Available An affective dimension is often at work in constructions of political ‘reality’. Such a recognition might be seen to reinforce the value of certain legacies in cultural studies, particularly the role of articulation in public debate, and the renewed importance of such work in framing responses to volatile issues like the mandatory detention of asylum seekers. Revisiting the work of Stuart Hall on Thatcherism, and taking note of Judith Brett’s recent history of the Australian Liberal Party, I want to contemplate the prominent role language plays in political life, and, alongside Watson and others, question the priority the Left accords this key element of contemporary politics. In doing so, I use Hall as an example of what might be called scholarly affect: a voice of intervention that catalyses the Left in moments of crisis, and a voice that deploys cultural theory to make sense of concrete political problems.

Financial considerations in living organ donation.

Science.gov (United States)

Jacobs, Cheryl; Thomas, Charlie

2003-06-01

The shortage of cadaveric organs and increased success of living donor transplantation support the use of living organ donors. Clinical social workers have the opportunity to explore a variety of donor-specific issues when performing psychosocial evaluations of living donors, including motivation, psychological stability, and personal and family consequences of donation, as well as the direct and indirect financial consequences faced by living donors. Although most donor-related medical costs are covered, other associated expenses are not reimbursable and may put donors at risk for financial hardship. Out-of-pocket expenses also serve as a disincentive to donate for some volunteers. During the evaluation process, healthcare professionals should openly discuss how surgery, recovery, and any potential complications might impact prospective donors' financial situation. Donors can then decide whether they are able to realistically handle the costs of donation. We present the financial dilemmas experienced by many living donors and highlight efforts that have been made to deal with them.

Don Quixote an Celia: the desire to live other lives

Directory of Open Access Journals (Sweden)

María Jesús Fraga Fernández-Cuevas

2012-12-01

Full Text Available The present study explores the parallelisms between Don Quixote and Elena Fortun’s novels Celia. First, it enumerates the various activities that prove the author’s interest in Cervantes and his work, as well as the possible intervention of her mentor, Maria Martinez Sierra, in the genesis of the child’s character. Both novels, of dialogical nature, share an episodic structure articulated by a weak storyline. Its protagonists are animated by the desire to live the lives of the characters of their favorite readings. They confuse fantasy and reality causing situations whose results are almost always adverse. If Don Quixote dies back to the reason, so will Celia, the girl, with her entry into adulthood by resigning her fantasies, which will be taken up by new generations of children.

The objective of this study was to evaluate progression to surgery rates for live and online seminar and assess weight loss outcome comparisons at 1-year postoperation. University Hospital Network, Allentown, PA, USA. The entry point into our program was an information seminar where prospective patients are educated about obesity, bariatric surgery, indications and contraindications, risks and benefits, and our center's process. Between January of 2009 and November of 2011, only live information seminars were offered. In November of 2011, we started offering an online information seminar to reach those who are unable to attend a live seminar. Tracking of live versus online seminar attendance was documented in our database. Between November 1, 2011 and September 30, 2015, 3484 people completed an information seminar. Of those, 2744 attendees came to a live seminar while 740 completed the online seminar. A significantly higher number of live seminar attendees, 78.1% (2144/2744) progressed to an office visit compared with online seminar attendees 66.5% (492/740), Ponline attendees (Ponline seminar, P = .65) and initial body mass index (46.3 ± 7.4 for live seminar versus 45.3 ± 7.1 for online seminar, P = .09) were very similar between the groups. Online seminar attendees' age (42.7 ± 12.1) was younger than that of the live seminar attendees' (47.3 ± 12.3) (P<.0001) but has little clinical value. Our results demonstrated that live seminar attendees are more likely to progress to surgery and therefore should continue to be offered. Copyright © 2018 American Society for Bariatric Surgery.

Renal Transplantation from Elderly Living Donors

2013-01-01

Full Text Available Acceptance of elderly living kidney donors remains controversial due to the higher incidence of comorbidity and greater risk of postoperative complications. This is a review of publications in the English language between 2000 and 2013 about renal transplantation from elderly living donors to determine trends and effects of donation, and the outcomes of such transplantation. The last decade witnessed a 50% increase in living kidney donor transplants, with a disproportionate increase in donors >60 years. There is no accelerated loss of kidney function following donation, and the incidence of established renal failure (ERF and hypertension among donors is similar to that of the general population. The overall incidence of ERF in living donors is about 0.134 per 1000 years. Elderly donors require rigorous assessment and should have a predicted glomerular filtration rate of at least 37.5 mL/min/1.73 m2 at the age of 80. Though elderly donors had lower glomerular filtration rate before donation, proportionate decline after donation was similar in both young and elderly groups. The risks of delayed graft function, acute rejection, and graft failure in transplants from living donors >65 years are significantly higher than transplants from younger donors. A multicentred, long-term, and prospective database addressing the outcomes of kidneys from elderly living donors is recommended.

History of bioengineering techniques for erosion control in rivers in Western Europe.

Evette, Andre; Labonne, Sophie; Rey, Freddy; Liebault, Frederic; Jancke, Oliver; Girel, Jacky

2009-06-01

Living plants have been used for a very long time throughout the world in structures against soil erosion, as traces have been found dating back to the first century BC. Widely practiced in Western Europe during the eighteenth and nineteenth centuries, bioengineering was somewhat abandoned in the middle of the twentieth century, before seeing a resurgence in recent times. Based on an extensive bibliography, this article examines the different forms of bioengineering techniques used in the past to manage rivers and riverbanks, mainly in Europe. We compare techniques using living material according to their strength of protection against erosion. Many techniques are described, both singly and in combination, ranging from tree planting or sowing seeds on riverbanks to dams made of fascine or wattle fences. The recent appearance of new materials has led to the development of new techniques, associated with an evolution in the perception of riverbanks.

The Gouy-Stodola Theorem in Bioenergetic Analysis of Living Systems (Irreversibility in Bioenergetics of Living Systems

Directory of Open Access Journals (Sweden)

Umberto Lucia

2014-09-01

Full Text Available Thermodynamics studies the transformations of energy occurring in open systems. Living systems, with particular reference to cells, are complex systems in which energy transformations occur. Thermo-electro-chemical processes and transports occur across their border, the cells membranes. These processes take place with important differences between healthy and diseased states. In particular, different thermal and biochemical behaviours can be highlighted between these two states and they can be related to the energy transformations inside the living systems, in particular the metabolic behaviour. Moreover, living systems waste heat. This heat is the consequence of the internal irreversibility. Irreversibility is effectively studied by using the Gouy-Stodola theorem. Consequently, this approach can be introduced in the analysis of the states of living systems, in order to obtain a unifying approach to study them. Indeed, this approach allows us to consider living systems as black boxes and analyze only the inflows and outflows and their changes in relation to the modification of the environment, so information on the systems can be obtained by analyzing their behaviour in relation to the modification of external perturbations. This paper presents a review of the recent results obtained in the thermodynamics analysis of cell systems.

2015-11-01

The L-Bar, New Mexico, Uranium Mill Tailings Radiation Control Act (UMTRCA) Title II Disposal Site was inspected on August 18, 2015. The tailings impoundment was in excellent condition. Erosion and vegetation measurements to monitor the condition of the impoundment cover indicated that no erosion is occurring, and perennial vegetation foliar cover at the measurement plots increased substantially compared to previous years due to above-average precipitation for the year. A short segment of the perimeter fence near the site entrance was realigned in spring 2015 because a gully was undermining the fence corner. Loose fence strands at another location were repaired during the inspection, and a section of fence needs to be realigned to avoid areas affected by deep gullies and sediment deposition. Inspectors identified no other maintenance needs or cause for a follow-up inspection. Groundwater monitoring is required every 3 years. The next monitoring event will be in 2016.

EFFECTIVENESS OF THE SANDPITS SECURITY SYSTEM AGAINST MICROORGANISMS AND INTESTINAL PARASITES SAND CONTAMINATION

Directory of Open Access Journals (Sweden)

2015-09-01

Full Text Available Playgrounds and sandpits (small architecture objects according to the Construction Law are subject to meticulous supervision, both at the design stage and subsequent status checks of the objects. One of the requirements arising from the need to protect playgrounds from animals is the necessity for fencing the object (Regulation of 31 December 2002 On Safety and Hygiene in Public and Private Schools and Institutions; Polish Standard PN-EN 1176 Playground equipment and surfacing. Does fencing playgrounds really reduce contamination of sand? To verify this hypothesis, the studies have been conducted on the residential areas’ sandpits, both fence secured and unsecured, located in close proximity to one another. The aim of the study was to evaluate the effectiveness of fences and nets as protection from microbial and parasite contamination of sandpits, mainly due to the access of animals to them. For several seasons of spring and summer the sand was examined in terms of the total number of heterotrophic bacteria and fungi (organic matter contamination of sand indicators and for the presence of coliform bacteria (including Escherichia coli, bacteria of the Salmonella genus and the eggs of intestinal parasites. It can be concluded that fencing playgrounds affects sand pollution less with waste and plant material (as a consequence, it has been reported statistically significantly less heterotrophic bacteria and fungi in the fenced sandpits’ sand. Unfortunately, the fence does not eliminate the risks associated with sand pollution of coliform bacteria. Cats and birds, but also dogs, still have a continuous access to sand. Due to the repeatedly stated carelessness of children and their caregivers, gates left open to the playground do not constitute an obstacle for domestic and stray animals. Another source of sand pollution with intestinal pathogens can be a manner of carriage of new sand, as there is no legislation governing the issue of transport

Just love in live organ donation.

Science.gov (United States)

Zeiler, Kristin

2009-08-01

Emotionally-related live organ donation is different from almost all other medical treatments in that a family member or, in some countries, a friend contributes with an organ or parts of an organ to the recipient. Furthermore, there is a long-acknowledged but not well-understood gender-imbalance in emotionally-related live kidney donation. This article argues for the benefit of the concept of just love as an analytic tool in the analysis of emotionally-related live organ donation where the potential donor(s) and the recipient are engaged in a love relation. The concept of just love is helpful in the analysis of these live organ donations even if no statistical gender-imbalance prevails. It is particularly helpful, however, in the analysis of the gender-imbalance in live kidney donations if these donations are seen as a specific kind of care-work, if care-work is experienced as a labour one should perform out of love and if women still experience stronger pressures to engage in care-work than do men. The aim of the article is to present arguments for the need of just love as an analytic tool in the analysis of emotionally-related live organ donation where the potential donor(s) and the recipient are engaged in a love relation. The aim is also to elaborate two criteria that need to be met in order for love to qualify as just and to highlight certain clinical implications.

Primary students' conceptions of living things

Science.gov (United States)

Legaspi, Britt Anne

Elementary school teachers are pressed for time throughout the instructional day to teach all curricular areas as expected by states and districts because of the current focus on reading and mathematics. Thus, foundational science concepts may be overlooked. For example, students' understandings of living and nonliving things may be overlooked by teachers, yet is useful in understanding the nature of living things. In this qualitative study, K-3 grade students were asked to sort objects as either living or nonliving and to give rationales for their choices. It was found that K-3 students readily used physical characteristics, such as having body parts, and physical abilities, such as being able to move, as criteria for living things. Students in grades 1 through 3 were able to articulate their reasons with more adult-like logic based on Jean Piaget' s research on developmental stages.

Live chat alternative security protocol

Indonesia is one of the largest e-commerce markets in Southeast Asia, as many as 5 million people do transactions in e-commerce, therefore more and more people use live chat service to communicate with customer service. In live chat, the customer service often asks customers’ data such as, full name, address, e-mail, transaction id, which aims to verify the purchase of the product. One of the risks that will happen is sniffing which will lead to the theft of confidential information that will cause huge losses to the customer. The anticipation that will be done is build an alternative security protocol for user interaction in live chat by using a cryptographic algorithm that is useful for protecting confidential messages. Live chat requires confidentiality and data integration with encryption and hash functions. The used algorithm are Rijndael 256 bits, RSA, and SHA256. To increase the complexity, the Rijndael algorithm will be modified in the S-box and ShiftRow sections based on the shannon principle rule, the results show that all pass the Randomness test, but the modification in Shiftrow indicates a better avalanche effect. Therefore the message will be difficult to be stolen or changed.

Biomechanical investigation of an alternative concept to angular stable plating using conventional fixation hardware

Directory of Open Access Journals (Sweden)

Radtke Roman

2010-05-01

Full Text Available Abstract Background Angle-stable locking plates have improved the surgical management of fractures. However, locking implants are costly and removal can be difficult. The aim of this in vitro study was to evaluate the biomechanical performance of a newly proposed crossed-screw concept ("Fence" utilizing conventional (non-locked implants in comparison to conventional LC-DCP (limited contact dynamic compression plate and LCP (locking compression plate stabilization, in a human cadaveric diaphyseal gap model. Methods In eight pairs of human cadaveric femora, one femur per pair was randomly assigned to receive a Fence construct with either elevated or non-elevated plate, while the contralateral femur received either an LCP or LC-DCP instrumentation. Fracture gap motion and fatigue performance under cyclic loading was evaluated successively in axial compression and in torsion. Results were statistically compared in a pairwise setting. Results The elevated Fence constructs allowed significantly higher gap motion compared to the LCP instrumentations (axial compression: p ≤ 0.011, torsion p ≤ 0.015 but revealed similar performance under cyclic loading (p = 0.43. The Fence instrumentation with established bone-plate contact revealed larger fracture gap motion under axial compression compared to the conventional LC-DCP osteosynthesis (p ≤ 0.017. However, all contact Fence specimens survived the cyclic test, whereas all LC-DCP constructs failed early during torsion testing (p Conclusions Even though accentuated fracture gap motion became obvious, the "Fence" technique is considered an alternative to cost-intensive locking-head devices. The concept can be of interest in cases were angle-stable implants are unavailable and can lead to new strategies in implant design.

Summary of the Skookumchuck Creek bull trout enumeration project 2001.; TOPICAL

Baxter, James S.; Baxter, Jeremy

2002-01-01

This report summarizes the second year of a bull trout (Salvelinus confluentus) enumeration project on Skookumchuck Creek in southeastern British Columbia. An enumeration fence and traps were installed on the creek from September 6th to October 12th 2001 to enable the capture of post-spawning bull trout emigrating out of the watershed. During the study period, a total of 273 bull trout were sampled through the enumeration fence. Length and weight were determined for all bull trout captured. In total, 39 fish of undetermined sex, 61 males and 173 females were processed through the fence. An additional 19 bull trout were observed on a snorkel survey prior to the fence being removed on October 12th. Coupled with the fence count, the total bull trout enumerated during this project was 292 fish. Several other species of fish were captured at the enumeration fence including westslope cutthroat trout (Oncorhynchus clarki lewisi), Rocky Mountain whitefish (Prosopium williamsoni), and kokanee (O. nerka). A total of 143 bull trout redds were enumerated on the ground in two different locations (river km 27.5-30.5, and km 24.0-25.5) on October 3rd. The majority of redds (n=132) were observed in the 3.0 km index section (river km 27.5-30.5) that has been surveyed over the past five years. The additional 11 redds were observed in a 1.5 km section (river km 24.0-25.5). Summary plots of water temperature for Bradford Creek, Sandown Creek, Buhl Creek, and Skookumchuck Creek at three locations suggested that water temperatures were within the temperature range preferred by bull trout for spawning, egg incubation, and rearing

Ross, Lainie Friedman; Thistlethwaite, J Richard

2018-01-01

Although national guidelines exist for evaluating the eligibility of potential living donors and for procuring their informed consent, no special protections or considerations exist for potential living donors who are incarcerated. Human research subject protections in the United States are codified in the Federal Regulations, 45 CFR 46, and special protections are given to prisoners. Living donor transplantation has parallels with human subject research in that both activities are performed with the primary goal of benefiting third parties. In this article, we describe what special considerations should be provided to prisoners as potential living donors using a vulnerabilities approach adapted from the human research subject protection literature.

Living with illness and self-transcendence: the lived experience of patients with spinal muscular atrophy.

2016-11-01

The aim of this study was to explore the lived experiences of patients afflicted with spinal muscular atrophy. Existing research studies on spinal muscular atrophy address the physical and psychological effects and complications of the disease; they also provide suggestions for how to improve the current management of this disease. However, information is limited on the disease process and the lived experience of spinal muscular atrophy patients. A phenomenological approach was conducted. Through 18 in-depth interviews recorded by a pen voice recorder, this study collected data obtained from a purposive sample of nine patients from the, 'Taiwan spinal muscular atrophy Families,' between November 2010-August 2011. The audio recordings were transcribed verbatim and data were analysed using Colaizzi's steps. Four themes and eight subthemes were identified: a loss of control (loss of muscular strength and independence), breaking limitations (assistive device use and mobility design), transcending limitations (independence/autonomy and social development) and living with hope (cherishing life and self-control). The results showed that the lived experiences of the spinal muscular atrophy patients involved living with illness, transcending the self and pursuing the meaning of life. Facing a life-threatening illness, these patients made self-adjustments in their lifestyles and exerted themselves to positively cope with hardships and maintain dignity and self-control. These findings could serve as evidence-based practice resources for healthcare professionals in helping individuals and their family members gain an in-depth understanding of spinal muscular atrophy's progression and life course and assist individuals in improving self-integrity to with hope. © 2016 John Wiley & Sons Ltd.

State of living PSA and further development

International Nuclear Information System (INIS)

1999-01-01

In October 1985 OECD-Principal Working Group (PWG 5) - Risk Assessment has initiated the Task Force 7 'Use of PSA in Nuclear Power Plant Management' to explore and report on the principles, characteristics, requirements and status of PSA oriented safety management. During this study, it became apparent that the utilisation of PSA techniques in nuclear plant safety management requires the development of supporting programmes to ensure that PSA models are being updated to reflect plant changes, and to direct their use towards the evaluation and determination of plant changes. These requirements also influence the software and hardware characteristics necessary to support the programme. This overall process is known as Living PSA. In this context OECD-PWG 5 has arranged international workshops on Living PSA application to support this development, to facilitate exchange of international experience and to summarise the state-of-the-art of L-PSA methodology. These activities were accompanied by following Task Groups of OECD-PWG 5 and the work results were published in state-of-the-art reports. According to the increasing development of Living PSA in the international field and its capacity to support plant safety management in a broad sense, OECD PWG 5 continues its work in setting up the Task Group 96-1 'State of Living PSA and Further Development' to clarify specific aspects of Living PSA. This report summarises the state of Living PSA in the international field based on the four Living PSA Workshops from 1988 to 1994 (Chapter 2) and the state of Reliability Data Collection based on the results of Task Group 12 'Reliability Data Collection and Analysis to Support PSA' and the two Data-Workshops from 1995 and 1998 (Chapter 3). The specific items of further development of Living PSA application as mentioned above are treated in Chapter 4. Chapter 5 gives a summary of the current state of Living PSA as well as outlook and recommendations of further development

The lived experience of men diagnosed with prostate cancer.

Krumwiede, Kelly A; Krumwiede, Norma

2012-09-01

To investigate the lived experience of prostate cancer from a patient perspective. Descriptive, qualitative. Community setting. 10 men with prostate cancer aged 62-70 years. A hermeneutic phenomenologic method using semistructured, open-ended questions addressing the lived experience. Phenomenology of praxis proposed by van Manen guided the data analysis and transformed personal experiences into disciplinary understanding. The use of van Manen's method of inquiry and analysis has contributed to the findings of the study by providing a way to explore the meaning of the lived experiences in an attempt to understand living with prostate cancer. Several themes were identified: living in the unknown, yearning to understand and know, struggling with unreliability of body, bearing the diagnosis of cancer, shifting priorities in the gap, and feeling comfort in the presence of others. Oncology nurses can use van Manen's four fundamental existentials-lived space (spatiality), lived body (corporeality), lived time (temporality), and lived other (relationality)-to understand the lived experience of prostate cancer. Nurses have many opportunities to impact the lives of men diagnosed with prostate cancer, including diagnosis, management of physical integrity, management of psychosocial integrity, and providing education. Nurses may encourage men to describe their diagnosis story and illness experience to better understand the meaning of the prostate cancer experience and to provide appropriate nursing care.

An Exploratory Note on Interstate Living-Cost Differentials

OpenAIRE

Cebula, Richard

1985-01-01

This exploratory study seeks to identify factors that systematically influence interstate living-cost differentials. Living costs refer to the average cost of living for a four-person family in each of the 50 states. For the year 1977, the living cost level is found to be an increasing function of population density, average income, and the degree of urbanization, while being a decreasing function of the presence of right-to-work laws.

Who Lives Alone During Old Age? Trends in the Social and Functional Disadvantages of Sweden's Solitary Living Older Adults.

Science.gov (United States)

Shaw, Benjamin A; Fors, Stefan; Fritzell, Johan; Lennartsoon, Carin; Agahi, Neda

2017-01-01

This study identifies specific social and functional disadvantages associated with living alone during old age in Sweden and assesses whether these associations have changed during recent decades. Data came from repeated cross-sectional surveys of Swedish adults aged 77+ during 1992-2014. Findings indicate that several types of disadvantage are consistently associated with the probability of living alone including financial insecurity and having never married for women and having never married and mobility impairment for men. Also for older men, low education has become an increasing strong determinant of living alone. These findings suggest that older adults who live alone are a subgroup that is particularly, and in some cases increasingly, vulnerable with respect to social and functional status. This has important policy implications related to addressing the needs of this growing subgroup as well as methodological implications for studies on the health effects of living alone.

To review ethical, legal and technical aspects of living kidney donor surgery. An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords: Donor nephrectomy; Kidney paired donation; Kidney transplantation; Laparoscopic nephrectomy; Living donor; Organs trafficking; Robotic assisted nephrectomy; Vaginal extraction. French legal documents have been reviewed using the government portal (http://www.legifrance.gouv.fr). Articles were selected according to methods, language of publication and relevance. A total of 6421 articles were identified; after careful selection, 161 publications were considered of interest and were eligible for our review. The ethical debate focuses on organ shortage, financial incentive, organ trafficking and the recent data suggesting a small but significant increase risk for late renal disease in donor population. Legal decisions aim to increase the number of kidneys available for donation, such as kidney-paired donation that faces several obstacles in France. Laparoscopic approach became widely used, while robotic-assisted donor nephrectomy failed to demonstrate improved outcome as compared with other minimal invasive techniques. Minimally invasive living donor nephrectomy aims to limit side effects in the donor without increasing the morbidity in this specific population of healthy persons; long term surveillance to prevent the onset of renal disease in mandatory.

Geographical aspects of geo-arbitrage: work in Canada and live in countries with low cost of living

Science.gov (United States)

Penney, J.; Dramowicz, K.

2016-04-01

The term geo-arbitrage means taking advantage of the difference in living costs between different geographic locations. This paper focuses on geographical aspects of international geo-arbitrage based on differences in the cost of living from one country to another. More precisely, the paper shows the perspective for a Canadian (student, volunteer, entrepreneur, IT person, or retiree) with some sort of mobile income or savings can take advantage of price differences by traveling to other countries. The paper is based on world development indicators, which cover a wide range of criteria when moving to another country. The data were collected for approximately 200 countries and represent the following categories of criteria: cost of living (economic factors), standard of living (such as safety, health care, environmental issues), and personal preferences (such as distance to home, Internet access or popularity of English language). The user input is required to rank or weight the importance of each of the criteria when moving to another country. One model was developed to emphasize the cost of living by controlling the weights ‘behind-the-scenes’. The results produce a list of the top suitable countries to practice geo-arbitrage. Another model allows the user to input weights for each criteria instead of ranks. The results from both models are mapped based on resulting suitability values. The top selected suitable countries are mapped, and the more specific information on each selected country is presented to the user, including the detailed cost of living, and current travel warning.

The Dominican population has a double-emigration pathway: one is to the USA, by proximity, and the other is to Spain, by sociocultural identification. Our aim was to determine attitudes toward living organ donation among Dominicans residing in Florida (USA) and Spain. All study participants were at least 15 years old and living in either Florida (USA) or Spain, and stratified by gender and age. A questionnaire on attitudes toward living kidney donation ("PCID-LKD Ríos") was used. The support of immigrant associations in Florida and Spain was required to advise on survey locations. Data obtained were anonymized and self-administered. The study questionnaire was completed by 123 Dominicans, 68% of whom were in favor of living related kidney donation. There were differences (P = .004) according to the country of residence. Eighty-one percent of Spain's Dominican residents were in favor, compared with 56% of Florida's residents. Factors associated with attitude toward donation were level of education (P donation (P = .006), attitude toward cadaveric organ donation (P donation (P = .046). Attitudes toward living kidney donation among immigrant Dominicans varies between Spain and the USA, with the former showing a more positive view. Copyright © 2017 Elsevier Inc. All rights reserved.

Living with an unfixable heart: a qualitative study exploring the experience of living with advanced heart failure.

LENUS (Irish Health Repository)

Ryan, Marie

2012-02-01

BACKGROUND: Nurses working with patients with advanced heart failure need knowledge that will help us to help patients cope with their situations of chronic illness. However, our knowledge bank is deficient due to the scarcity of inquiry that takes the affected person\\'s point of view as its central focus. AIM: The aim of this study was to describe patients\\' experiences of living with advanced heart failure. METHODS: The study sample (N=9) consisted of male (N=6) and female (N=3) patients with advanced (NYHA classes III-IV) heart failure. The design was qualitative and open unstructured interviews were audio-taped and transcribed verbatim during 2006. RESULTS: Four main themes emerged: Living in the Shadow of Fear; Running on Empty; Living a Restricted life; and Battling the System. The experience of living with advanced heart failure was described as a fearful and tired sort of living characterised by escalating impotence and dependence. CONCLUSIONS: The findings suggest that there may be an illogical but enduring ethos of \\'cure\\' pervading health care worker\\'s attitudes to advanced heart failure care. This mindset might be working to hinder the application of additional or alternative therapies, which might better palliate the physical and psychosocial distress of patients.

How Live Performance Moves the Human Heart.

Directory of Open Access Journals (Sweden)

Haruka Shoda

Full Text Available We investigated how the audience member's physiological reactions differ as a function of listening context (i.e., live versus recorded music contexts. Thirty-seven audience members were assigned to one of seven pianists' performances and listened to his/her live performances of six pieces (fast and slow pieces by Bach, Schumann, and Debussy. Approximately 10 weeks after the live performance, each of the audience members returned to the same room and listened to the recorded performances of the same pianists' via speakers. We recorded the audience members' electrocardiograms in listening to the performances in both conditions, and analyzed their heart rates and the spectral features of the heart-rate variability (i.e., HF/TF, LF/HF. Results showed that the audience's heart rate was higher for the faster than the slower piece only in the live condition. As compared with the recorded condition, the audience's sympathovagal balance (LF/HF was less while their vagal nervous system (HF/TF was activated more in the live condition, which appears to suggest that sharing the ongoing musical moments with the pianist reduces the audience's physiological stress. The results are discussed in terms of the audience's superior attention and temporal entrainment to live performance.

Canada: Living with radiation

International Nuclear Information System (INIS)

1995-01-01

Canadians are exposed daily to a variety of naturally occurring radiation. Heat and light from the sun, are familiar examples. Radium and uranium are naturally occurring materials which have been found to emit radiation and so have been called radioactive. There are also various types of artificially produced forms of radiation that are employed routinely in modern living, such as radio and television waves and microwaves. X-rays, another common type of radiation, are widely used in medicine as are some man-made radioactive substances. These emit radiation just like naturally occurring radioactive materials. Surveys have shown that many people have a poor understanding of the risks associated with the activities of modern living. Exposure to ionizing radiation from radioactive materials is also considered by many persons to have a high risk, This booklet attempts to inform the readers about ionizing radiation, its uses and the risks associated with it, and to put these risks in perspective with the risks of other activities and practices. A range of topics from medical uses of radiation to emergency planning, from biological effects of radiation to nuclear power, each topic is explained to relate radiation to our everyday lives. 44 figs

2014-09-01

In addition to good medical care, living environment is of central importance in encouraging social participation among older people. Therefore, municipalities should prioritise the age-appropriate design of living environments. Results of the KORA Age study were presented at the regional conference "Living environment, age and health" in the Augsburg town hall on October 1, 2013. The results on participation and living environment were discussed with local policy makers and senior citizens' representatives from Augsburg and two surrounding regions. The study examined the impact of living environment on participation using two different approaches: qualitative findings from focus group discussions and quantitative findings based on telephone interviews and the use of a geographic information system. The results were complemented by contributions from a regional and national perspective. It was stressed in the closing discussion that a senior-friendly living environment can only be created by using a broad range of different measures. On the one hand physical barriers need to be removed, while at the same time the sense of community, neighborhood cohesion and solidarity should be encouraged further.

Seniors' experiences of living in special housing accommodation

Hellberg, Ingela; Augustsson, Veronica; Hellström Muhli, Ulla

2011-01-01

This article presents a hermeneutic phenomenological analysis of interview material in which 12 seniors living in Special Housing Accommodation (SHA) facilities reflect on the experience of living in such facilities. Of particular interest in the analysis is living in a SHA as a phenomenon. The finding shows that the phenomenon of lived experience in a SHA seems to be a state of ambiguity regarding one's existence, which is made up of several constituents (elements of meaning). The analysis contributes to the understanding of how the phenomenon of SHA living is coming into existence as a need, due to an individual's failing health; however, the SHA is not considered to be a true home. Accordingly, this has consequences to the subject position for the seniors in that they have to navigate between existing and not existing. The seniors learn to cope with living in the SHA by lowering their expectations of life and existence while the SHA provides the prerequisites for their existence. An implication for promoting care is to support the seniors to enable a full existence of life within SHA living. PMID:21412446

Internal migration and household living conditions in Ethiopia

Directory of Open Access Journals (Sweden)

Blessing Uchenna Mberu

2006-06-01

Full Text Available Using the 1998 Migration, Gender and Health Survey in Five Regions of Ethiopia, and multivariate regression techniques, this paper examines the relationship between internal migration and household living conditions. The analysis finds significant living condition advantage of permanent and temporary migrants over non-migrants. These advantages are primarily linked to migration selectivity by education and non-agricultural income. Once the independent effects of these variables are controlled, no statistical significant independent association exists between migration status and living conditions. Government policies of resettlement in the 1980s and ethnic federalism of the 1990s may have engendered stress migration and exacerbated poor living outcomes for return migrants. The resort to migration and/or resettlement as an individual or government policy response to periodic unfavorable conditions in places of origin is not strongly supported by this analysis as the key to improved living conditions. Promoting higher education and opportunities for employment outside the agricultural sector are more likely to yield improved living conditions in Ethiopia.

Subsidized Fencing of Livestock as a Means of Increasing Tolerance for Wolves

Directory of Open Access Journals (Sweden)

Jens Karlsson

2011-03-01

Full Text Available Studies of how proactive measures to reduce livestock depredation by carnivores affect human tolerance toward carnivores are extremely rare. Nevertheless, substantial amounts of money are spent each year on proactive measures to facilitate large carnivore conservation. The objective of this study was to assess how subsidies for proactive measures to reduce sheep losses to wolves are associated with public attitudes toward wolves. The respondents were 445 people living inside wolf territories in Sweden. Our data set is unique because we combine wolf territory level information regarding proactive subsidies and wolf attacks on dogs and sheep with geographical information of the respondents. Consequently, the respondents can be assigned to a specific wolf territory. The number of wolf attacks on sheep and dogs in the respective territories as well as the number of years that the wolf territory had existed did not affect human attitudes toward wolves. Subsidies for proactive measures to reduce wolf predation on sheep significantly increased positive attitudes toward wolf presence on the local scale. The magnitude of the effect of subsidies for proactive measures was comparable to the effect of other variables well known to affect human attitudes toward wolves such as age or education. Our data show that subsidies not only made the already positive more positive, but also made people with negative attitudes to wolf presence locally, less negative. Our conclusion is, therefore, that subsidies for proactive measures are an effective tool when working with "the human dimension" of conservation biology.

2016-01-01

Objectives This study examines how living arrangements are associated with suicidal ideation for older adults in South Korea, which has the highest suicide rate among OECD countries, and a particularly high suicide rate for older persons. Methods Analyzing a sample of 5,795 women and 3,758 men aged 65 and older from a nationwide representative cross-sectional data set, we examined how many older adults think about suicide over a one-year period, why they think about suicide, and whether living arrangements are associated with suicidal ideation. Results About one out of twelve respondents in our sample reported suicidal ideation. While women and men did not differ in the prevalence of suicidal ideation, women attributed their suicidal feelings to health problems, while men attributed theirs to economic difficulties. Logistic regression results indicated that living arrangements are associated with suicidal ideation for men but not women. Older men living with a spouse were less likely to have suicidal ideation than older men with other living arrangements (i.e., living alone, living with children without spouse, living with spouse and others). Conclusions Our results highlight the importance of living arrangements to older men’s suicidal ideation. We discuss gender differences in the implications of living arrangements to suicidal ideation within the context of Confucian culture. PMID:26317145

Anastasia Apostolides

2014-11-01

Full Text Available This article will argue that the recent turn towards lived theology or religion in practical theology can offer a useful hermeneutic to interpret the impact of the Harry Potter series on the spiritual formation and identity creation of adolescents. In practical theology there has been a turn towards lived theology or religion as lived religion has moved out of institutions into social–cultural phenomena as people seek to find meaning and purpose for their lives in alternative places to institutionalised religion.

Live from the Arctic

Warnick, W. K.; Haines-Stiles, G.; Warburton, J.; Sunwood, K.

2003-12-01

For reasons of geography and geophysics, the poles of our planet, the Arctic and Antarctica, are places where climate change appears first: they are global canaries in the mine shaft. But while Antarctica (its penguins and ozone hole, for example) has been relatively well-documented in recent books, TV programs and journalism, the far North has received somewhat less attention. This project builds on and advances what has been done to date to share the people, places, and stories of the North with all Americans through multiple media, over several years. In a collaborative project between the Arctic Research Consortium of the United States (ARCUS) and PASSPORT TO KNOWLEDGE, Live from the Arctic will bring the Arctic environment to the public through a series of primetime broadcasts, live and taped programming, interactive virtual field trips, and webcasts. The five-year project will culminate during the 2007-2008 International Polar Year (IPY). Live from the Arctic will: A. Promote global understanding about the value and world -wide significance of the Arctic, B. Bring cutting-edge research to both non-formal and formal education communities, C. Provide opportunities for collaboration between arctic scientists, arctic communities, and the general public. Content will focus on the following four themes. 1. Pan-Arctic Changes and Impacts on Land (i.e. snow cover; permafrost; glaciers; hydrology; species composition, distribution, and abundance; subsistence harvesting) 2. Pan-Arctic Changes and Impacts in the Sea (i.e. salinity, temperature, currents, nutrients, sea ice, marine ecosystems (including people, marine mammals and fisheries) 3.

Estimating biodegradation half-lives for use in chemical screening.

Aronson, Dallas; Boethling, Robert; Howard, Philip; Stiteler, William

2006-06-01

Biodegradation half-lives are needed for many applications in chemical screening, but these data are not available for most chemicals. To address this, in phase one of this work we correlated the much more abundant ready and inherent biodegradation test data with measured half-lives for water and soil. In phase two, we explored the utility of the BIOWIN models (in EPI Suite) and molecular fragments for predicting half-lives. BIOWIN model output was correlated directly with measured half-lives, and new models were developed by re-regressing the BIOWIN fragments against the half-lives. All of these approaches gave the best results when used for binary (fast/slow) classification of half-lives, with accuracy generally in the 70-80% range. In the last phase, we used the collected half-life data to examine the default half-lives assigned by EPI Suite and the PBT Profiler for use as input to their level III multimedia models. It is concluded that estimated half-lives should not be used for purposes other than binning or prioritizing chemicals unless accuracy improves significantly.

Medicaid expenditures for children living with smokers

Directory of Open Access Journals (Sweden)

Levy Douglas E

2011-05-01

Full Text Available Abstract Background Children's exposure to secondhand smoke is associated with increased morbidity. We estimated Medicaid expenditures for children living with smokers compared to those living with no smokers in the United States. Methods Data were overall and service-specific (i.e., inpatient, ambulatory, emergency department, prescription drug, and dental annual Medicaid expenditures for children 0-11 years old from the 2000-2007 Medical Expenditures Panel Surveys. Smokers' presence in households was determined by adult respondents' self reports. There were 25,835 person-years of observation. We used multivariate analyses to adjust for child, parent, and geographic characteristics. Results Children with Medicaid expenditures were nearly twice as likely to live with a smoker as other children in the U.S. population. Adjusted analyses revealed no detectable differences in children's overall Medicaid expenditures by presence of smokers in the household. Medicaid children who lived with smokers on average had $10 (95% CI $3, $18 higher emergency department expenditures per year than those living with no smokers. Conclusions Living with at least one smoker (a proxy for secondhand smoke exposure is unrelated to children's overall short-term Medicaid expenditures, but has a modest impact on emergency department expenditures. Additional research is necessary to understand the relationship between secondhand smoke exposure and long-term health and economic outcomes.

LIVE ATTENUATED VACCINES FOR THE IMMUNOPROPHYLAXIS

Directory of Open Access Journals (Sweden)

O. A. Shamsutdinova

2017-01-01

Full Text Available The review focuses on the history of the production of live antiviral vaccines and their use for the prevention of infectious diseases. It was noted that before the beginning of the 20th century, only three live vaccines were developed and put into practice — against smallpox, rabies, plague. The discovery of D. Enders, T.H. Weller and F.Ch. Robins of the ability of the polio virus, and then of a number of other viruses, to reproduce in vitro in cell cultures of various types, greatly expanded the studies on the production of attenuated strains of viruses for live vaccines. The historical stages of obtaining and introducing live vaccines for the prevention of smallpox, poliomyelitis, measles, rubella, and mumps are highlighted. Arguments in favor of the use of associated vaccine preparations for the prevention of viral infections are presented. Various variants of the strategy and tactics of using live vaccines, which are used for specific prevention of viral infections in different countries, are described. The review provides information on technological methods for obtaining antiviral vaccines. The publications testifying to the development of specific reactions in immunized vaccine strains of measles, mumps, poliomyelitis and rubella viruses, such as aseptic meningitis (vaccine strains of mumps virus, acute arthritis (vaccine rubella virus strains, temperature reactions, rash (vaccine strains of the virus Measles, vaccine-associated paralytic poliomyelitis (VAPP vaccine vaccine poliovirus. It is particularly noted that the long experience of vaccine prevention both in Russia and abroad convincingly shows that the risk of developing post-vaccination complications is incommensurably lower than the risk of causing harm to health from the corresponding infections. It is concluded that despite introduction of new third and fourth generation vaccines into practice, live attenuated vaccines do not lose their significance and are used in vaccine

Park, Joon Soo; Lee, Min Jung; Chung, Ki Hun; Ko, Dong Kyun; Chung, Hyun

2013-12-01

Live bee acupuncture (Bong-Chim) dermatitis is an iatrogenic disease induced by so-called live bee acupuncture therapy, which applies the honeybee (Apis cerana) stinger directly into the lesion to treat various diseases in Korea. We present two cases of live bee acupuncture dermatitis and review previously published articles about this disease. We classify this entity into three stages: acute, subacute, and chronic. The acute stage is an inflammatory reaction, such as anaphylaxis or urticaria. In the chronic stage, a foreign body granuloma may develop from the remaining stingers, similar to that of a bee sting reaction. However, in the subacute stage, unlike bee stings, we see the characteristic histological "flame" figures resulting from eosinophilic stimulation induced by excessive bee venom exposure. We consider this stage to be different from the adverse skin reaction of accidental bee sting. © 2013 The International Society of Dermatology.

Strategies for Living in Houses

Directory of Open Access Journals (Sweden)

Colin Ripley

2017-12-01

Full Text Available The problem of queer housing can never go away because it is a central component of queerness. Queer housing is a contradiction in terms: not even a queer architect can design a queer house. But where does this leave us, as queer people living in a straight hegemony? Where does it leave us as humans with bodies, craving shelter and safety and a place to live that is in accordance with our experience of self and of living in the world? In this article the author proposes eight architectural strategies for re-occupying the Levittown Cape Cod house from 1947 for queer bodies, minds and hearts. These strategies offer modes by which the key programmatic formal and material components of the Cape Cod House can be attacked, made invalid, or détourned for queer uses, to make of the Cape Cod House a site for our pain, our longing, our anger.

The experience of living with adult-onset epilepsy.

Science.gov (United States)

Kılınç, Stephanie; van Wersch, Anna; Campbell, Carol; Guy, Alison

2017-08-01

The incidence and prevalence of adults diagnosed with epilepsy is higher compared to those diagnosed in childhood, yet the experience of living with adult-onset epilepsy has rarely been examined. Hence, the current study took a phenomenological approach to examining the experience of living with epilepsy following diagnosis in adulthood. Semi-structured interviews were conducted with 39 people from across the UK, diagnosed with epilepsy between the ages of eighteen and sixty, at two points in time, six months apart. Phenomenological analysis identified three central themes: the unpredictability of seizure occurrence; the ripple effect; and re-evaluating the future. Despite the accepted consensus in the epilepsy literature that living and coping with epilepsy becomes more difficult the older a person is diagnosed, the current findings indicated that this is inadequate. Rather, it is more suitable to consider that those living with adult-onset epilepsy have a specific experience of the condition and particular support needs, given that they once lived their lives as people without epilepsy.

Children's reasons for living, self-esteem, and violence.

Science.gov (United States)

Merwin, Rhonda M; Ellis, Jon B

2004-01-01

Attitudes toward violence and reasons for living in young adolescents with high, moderate, and low self-esteem were examined. The authors devised an Attitudes Toward Violence questionnaire; the Rosenberg's Self-esteem Scale (RSE) and the Brief Reasons for Living in Adolescents (BRFL-A) was used to assess adaptive characteristics. The independent variables were gender and self-esteem. The dependent variables were total Reasons for Living score and Attitudes Toward Violence score. Participants included 138 boys and 95 girls, ages 11 to 15 years (M = 13.3) from a city middle school. The results showed that for the dependent variable attitudes toward violence, main effects were found for both gender and self-esteem. For the dependent variable reasons for living, a main effect was found for self-esteem but not for gender. An inverse relationship was found between violence and reasons for living. Being male and low self-esteem emerged as predictors of more accepting attitudes toward violence. Low self-esteem was significantly related to fewer reasons for living.

"Living high - training low" vs. "living high - training high": erythropoietic responses and performance of adolescent cross-country skiers.

Christoulas, K; Karamouzis, M; Mandroukas, K

2011-03-01

To determine and compare the erythropoietic response and exercise performance of adolescent cross-country skiers, as a result of "living high-training high" (HH) and "living high-training low" (HL). Nine female and six male adolescent cross-country skiers volunteered to participate in separate trials. In the first trial (HH), the skiers lived and trained for 21 days at 1550-2050 m, while in the second trial (HL) they trained near sea level (450-500 m) but resided at 1550 m. All participants underwent maximal cycle ergometer tests for the determination of VO2max and cardiorespiratory parameters via an open circuit system at sea level before ascent to altitude, and 1-2 days after descent from altitude. Blood samples were drawn prior to and immediately after maximal cycle exercise testing, at sea level prior to ascent, on days 1 (D1) and 21 (D21) at altitude (1740 m), and 1-2 days post-altitude, for the determination of serum erythropoietin (EPO) concentration, haemoglobin (Hb), hematocrit (Ht), and red blood cell (RBC) volume. The results showed that both boys and girls cross-country skiers, significantly improved their sea level VO2max after 21 days of living at moderate altitude and training near sea level. The present study demonstrates that living at moderate altitude, 1550-2050 m and training low, near sea level (450-500 m) significantly increases VO2max and RBC mass for both boys and girls. Results indicate that applying the training concept "living high - training low" in adolescent athletes may improve their endurance performance.

While in its early years the HIV epidemic affected primarily the male and the young, nowadays, the population living with HIV/AIDS is approximately 24% women, and its age composition has shifted towards older ages. Many of the older women who live with HIV/AIDS also live with the medical and social conditions that accompany aging. This work aims to identify and characterize empirical studies of strategies for the comprehensive management of women over 40, including transgender women, who live with HIV/AIDS. Forty was chosen as an operational age cutoff to identify premenopausal women who are less likely to bear children, as well as peri- and postmenopausal women. We conducted a literature search after discussions with a diverse panel of content experts and other stakeholders and developed an evidence map that identified 890 citations that address questions having to do with programs and barriers to engaging with programs, as well as the role of insurance and comorbidities, and have enrolled older women who live with HIV/AIDS. Of these, only 37 (4%) reported results of interest for women over 40 who live with HIV/AIDS, or examined interactions between gender and older age that would allow predictions in this subgroup. Few of the 37 eligible studies focused on women facing obvious challenges, such as immigrants, transgender, physically abused, or those recently released from prison. No studies focused on women caring for dependents, including children and grandchildren, or those diagnosed after age 40. The evidence base that is directly applicable to women over 40 who live with HIV/AIDS in the USA is limited, and the research need is broad. We propose research prioritization strategies for this population.

'They don't live in my house every day': How understanding lives can aid understandings of smoking.

Science.gov (United States)

Robinson, Jude; Holdsworth, Clare

2013-03-01

While the prevalence of smoking in western countries has substantially reduced following the introduction of comprehensive tobacco control programs, reduction strategies such as the introduction of smokefree legislation, media campaigns and individual and group support for people trying to quit have been less successful with people living on low income, suggesting the need for new ways to engage with people who smoke. We argue that, rather than focusing solely on researching smoking behaviors to generate new understandings of why people smoke, people working in the broad area of public health should look more widely at peoples' lives in order to understand their smoking. Using a biographical, narrative perspective as part of a wider ethnographic study of 12 families living in one community within Liverpool in 2006, we argue that understandings that position smoking purely as a harmful, deviant behavior, fail to capture the cultural complexity of the lives of smokers and the changing place and meaning of cigarettes over a person's lifetime, and may explain why smokers fail to engage with smoking cessation services and continue to smoke.

To understand the daily lives of people with Parkinson's disease. Qualitative research, using as methodological and theoretical referential the Grounded Theory and Symbolic Interactionism, respectively. The in-depth interview was conducted with 30 people with Parkinson's disease. From data analysis, three themes were selected: Living with the disease - living with the treatment and changes in lifestyle; Modifying of one's job performance - revealing incapacity for work and the need to anticipate retirement and; Living with the stigma - the feeling of prejudice against the disease and the perceived limitations of the health services. Living with a chronic and non-transferable disease encompasses social, physical and cultural effects, along with the personal experiences of each unique individual. This study assists the improvement of care to people with the disease, because the care practice emerges from the interactions between the subjects.

Applicability of living PSA in NPP modernization

International Nuclear Information System (INIS)

Himanen, R.

1999-01-01

Recently the utility Teollisuuden Voima Oy (TVO) has modernized the Olkiluoto 1 and 2 nuclear units and increased the net electric power by 18 per cent. Level 2 PSA was performed during the modernization project and the living level 1 PSA was used to support the design of the plant modifications. The plant specific living PSA model was a powerful tool when evaluating modernization alternatives. Successive support of safety management with the PSA model requires, that both the utility and the Regulatory Body understand capability and limitations of the model in details. TVO has prepared an internal procedure that presents in detail the practices and responsibilities concerning living PSA. The procedure is based on general guidelines and requirements on probabilistic safety analysis of nuclear power plants in Finland, released by the Regulatory Body. Living PSA requires that also the procedure for the use of living PSA is living. The recently published USNRC Regulatory Guides on PSA will be taken into account in the next version of the TVO PSA procedure. The PSA Peer Review Certification Process is one way to evaluate the quality of PSA in general, but also to detect the weaknesses of the PSA. However, the Certification Process cover only limited scope of PSA omitting e.g. all other external events except internal floods. This paper gives an overview on the scope of living PSA for Olkiluoto 1 and 2, and presents some examples on the real use of PSA concerning the modernization of the plant. Definition of quantitative dependability requirements for renovated systems is possible, but on the other hand, proving of these targets is in some cases extremely difficult, because of lacking dependability data. The problems are mainly concerned in systems with of programmable logic control. (au)

Religiosity and spirituality as resilience strategies among long-living older adults in their daily lives

Directory of Open Access Journals (Sweden)

Luana Araújo dos Reis

Full Text Available ABSTRACT Objective: to investigate religiosity and spirituality as a resilience strategy for the long-living older adults in their daily lives. Method: Qualitative research of phenomenological approach based on Martin Heidegger thoughts. Interviews were conducted with 14 older adults registered at a family health unit in the city of Jequié, BA, Brazil. The data were analyzed in the light of Being and Time. Results: The results revealed that God occupies a central position in their lives, and the reading of the bible, praying the rosary and prayers are resilience strategies used for coping with unfavorable situations, recovery and/or maintenance of health, personal and family protection, and, above all, the experience of a satisfactory aging. Final considerations: Religiosity and spirituality were presented as an important resilience strategy in the existence of older adults, showing that through them it is possible to achieve well-being and cope with health and social problems.

4Pi-confocal microscopy of live cells

Science.gov (United States)

Bahlmann, Karsten; Jakobs, Stefan; Hell, Stefan W.

2002-06-01

By coherently adding the spherical wavefronts of two opposing lenses, two-photon excitation 4Pi-confocal fluorescence microscopy has achieved three-dimensional imaging with an axial resolution 3-7 times better than confocal microscopy. So far this improvement was possible only in glycerol-mounted, fixed cells. Here we report 4Pi-confocal microscopy of watery objects and its application to the imaging of live cells. Water immersion 4Pi-confocal microscopy of membrane stained live Escherichia coli bacteria attains a 4.3 fold better axial resolution as compared to the best water immersion confocal microscope. The resolution enhancement results into a vastly improved three-dimensional representation of the bacteria. The first images of live biological samples with an all-directional resolution in the 190-280 nm range are presented here, thus establishing a new resolution benchmark in live cell microscopy.

Two recent matched cohort studies from the USA and Norway published in 2014 have raised some concerns related to the long-term safety of kidney living donation. Further studies on the long-term risks of living donation have since been published. In this position paper, Developing Education Science...... and Care for Renal Transplantation in European States (DESCARTES) board members critically review the literature in an effort to summarize the current knowledge concerning long-term risks of kidney living donation to help physicians for decision-making purposes and for providing information...... to the prospective live donors. Long-term risk of end-stage renal disease (ESRD) can be partially foreseen by trying to identify donors at risk of developing ‘de novo’ kidney diseases during life post-donation and by predicting lifetime ESRD risk. However, lifetime risk may be difficult to assess in young donors...

Radioactive nuclides in the living environment

There are several radioactive nuclides in the living environment, such as those existing since the creation of the earth, those coming from experimental nuclear explosions, and radiations of the cosmic rays. A lesson on these radioactive nuclides was considered useful for understanding the place of nuclear technology, and have been made on the title of 'Radioactive Nuclides in the Living Environment' in the general course of the Nuclear Engineering School of Japan Atomic Energy Research Institute. When the curriculum of the general course was modified in 1993, the lesson was left in a changed form. Thus, the textbook of the lesson is presented in this report. The contents are natural and artificial radioactive nuclides in the living environment and where they have come from etc. (author)

Living unrelated donors in kidney transplants: better long-term results than with non-HLA-identical living related donors?

Science.gov (United States)

Given the severe organ shortage and the documented superior results obtained with living (vs. cadaver) donor kidney transplants, we have adopted a very aggressive policy for the use of living donors. Currently, we make thorough attempts to locate a living related donor (LRD) or a living unrelated donor (LURD) before proceeding with a cadaver transplant. We compared the results of our LURD versus LRD transplants to determine any significant difference in outcome. Between 1/1/84 and 6/30/98, we performed 711 adult kidney transplants with non-HLA-identical living donors. Of these, 595 procedures used LRDs and 116 used LURDs. Immunosuppression for both groups was cyclosporine-based, although LURD recipients received 5-7 days of induction therapy (antilymphocyte globulin or antithymocyte globulin), whereas LRD recipients did not. LURD recipients tended to be older, to have inferior HLA matching, and to have older donors than did the LRD recipients (all factors potentially associated with decreased graft survival). Short-term results, including initial graft function and incidence of acute rejection, were similar in the two groups. LURD recipients had a slightly higher incidence of cytomegalovirus disease (P=NS). We found no difference in patient and graft survival rates. However, the incidence of biopsy-proven chronic rejection was significantly lower among LURD recipients (16.7% for LRD recipients and 10.0% for LURD recipients at 5 years posttransplant; P=0.05). LRD recipients also had a greater incidence of late (>6 months posttransplant) acute rejection episodes than did the LURD recipients (8.6% vs. 2.6%, P=0.04). The exact reason for these findings is unknown. Although LURD recipients have poorer HLA matching and older donors, their patient and graft survival rates are equivalent to those of non-HLA-identical LRD recipients. The incidence of biopsy-proven chronic rejection is lower in LURD transplants. Given this finding and the superior results of living donor (vs

LiveWall Operational Evaluation: Seattle Law Enforcement Pilot

Energy Technology Data Exchange (ETDEWEB)

Barr, Jonathan L.; Burtner, Edwin R.; Stein, Steven L.

2013-10-01

The LiveWall concept envisioned as an outgrowth of the Precision Information Environment (PIE) project allows communications between separate groups using interactive video, audio, and a shared desktop environment; this allows everyone to participate and collaborate in real time, regardless of location. The LiveWall concept provides a virtual window to other locations, where all parties can interact and collaboratively work with each other. This functionality is intended to improve multi-site coordination amongst emergency operations centers (EOC), field operations sites and across organizations and jurisdictions to accommodate communications during routine and emergency events. For the initial LiveWall operational evaluation PNNL partnered with the Seattle Police Department (SPD). This partnership allowed for the creation of an excellent LiveWall test bed specific to law enforcement. This partnership made it possible to test the LiveWall concept with scenarios involving the many facets of the law enforcement work done by SPD. PNNL and SPD agreed that integrating the systems into operations for a real event would be the best test of the technology and give SPD staff greater visibility into the functionality and benefits offered by the LiveWall concept.

Half-lives for selected actinides and long-lived radionuclides

International Nuclear Information System (INIS)

Holden, N.E.

1988-01-01

Long-lived actinide nuclides are of interest for their use in nuclear reactors, for nuclear reactor burnup studies in waste management, and for safeguard applications, e.g., α counting is used to determine the amount of material present. Some long-lived radionuclides are of interest for their use in determining geological ages using various dating methods, and in calculating the cosmic-ray exposure ages of meteorites. Recommended values are presented for both the total half-life and for the spontaneous fission half-life of /sup 232-236,238/U, of /sup 236,238-242,244/Pu, of /sup 241,242m,243/Am, and of /sup 242-248,250/Cm. Problems with the presentation of uncertainties are discussed. The impact of the revised 14 C half-life on the carbon dating technique and various 14 C ages is discussed. The possible primordial occurrence of 92 Nb is now definitely ruled out. Based on examination of the 26 Al half-life, the calculated value for the cosmic-ray exposure age of meteorites remains too high compared to the age calculated using other radionuclide half-life values. 204 Pb, which was once thought to be radioactive, is shown to be stable. 37 refs., 5 tabs

Dead-time correction formulae are established in the general case of superimposed non-homogeneous Poisson processes. Based on the same principles as conventional live-timed counting, this method exploits the additional information made available using digital signal processing systems, and especially the possibility to store the time stamps of live-time intervals. No approximation needs to be made to obtain those formulae. Estimates of the variances of corrected rates are also presented. This method is applied to the activity measurement of short-lived radionuclides. Copyright © 2017 Elsevier Ltd. All rights reserved.

Living arrangements and suicidal ideation among the Korean older adults.

Kim, Jibum; Lee, Yun-Suk; Lee, Jinkook

2016-12-01

This study examines how living arrangements are associated with suicidal ideation for older adults in South Korea, which has the highest suicide rate among OECD countries, and a particularly high suicide rate for older persons. Analyzing a sample of 5795 women and 3758 men aged 65 and older from a nationwide representative cross-sectional data-set, we examined how many older adults think about suicide over a one-year period, why they think about suicide, and whether living arrangements are associated with suicidal ideation. About 1 out of 12 respondents in our sample reported suicidal ideation. While women and men did not differ in the prevalence of suicidal ideation, women attributed their suicidal feelings to health problems, while men attributed theirs to economic difficulties. Logistic regression results indicated that living arrangements are associated with suicidal ideation for men but not women. Older men living with a spouse were less likely to have suicidal ideation than older men with other living arrangements (i.e., living alone, living with children without spouse, living with spouse, and others). Our results highlight the importance of living arrangements to older men's suicidal ideation. We discuss gender differences in the implications of living arrangements to suicidal ideation within the context of Confucian culture.

There are individuals, including children, dying needlessly in poverty-stricken third world countries. Many of these deaths could be prevented if pharmaceutical companies provided the drugs needed to save their lives. Some believe that because pharmaceutical companies have the power to save lives, and because they can do so with little effort, they have a special obligation. I argue that there is no distinction, with respect to obligations and responsibilities, between pharmaceutical companies and other types of companies. As a result, to hold pharmaceutical companies especially responsible for saving lives in third world countries is unjustified.

1997-10-01

Living related liver transplantation (LRLT) has been developed in response to the paediatric organ donor shortage. According to the International Living Donor Registry, 521 transplants had been performed in 515 patients between December 8 1988 and January 19 1996 in 30 centres worldwide. The overall actuarial patient and graft survival rates were 82.7 and 80%, respectively. Between June 17 1994 and November 30 1996, the authors performed 11 LRLT at the Chung Gung Memorial Hospital. The living donors consisted of 10 mothers and one father. The mean graft weight was 303 g and the mean graft recipient weight ratio was 2.2%. Donor hepatectomy was performed without vascular inflow occlusion. The intra-operative blood loss ranged from 30 mL to 120 mL with an average of 61 mL, and blood transfusion was not required in all donors both intra-operatively and during the postoperative period. Underlying diseases of the recipients were biliary atresia (n = 10) and glycogen storage disease (n = 1). The mean graft cold ischaemia time was 106 min, the mean second warm ischaemia time was 51 min and the mean interval between portal and arterial reperfusion was 81 min. The initial LRLT results were promising with all donors having been discharged without complication. The recipients experienced a few complications, all of which were manageable with early intervention. All 11 recipients are alive and well. These are encouraging results and the authors hope to expand the use of live donors for liver transplantation to cope with demand.

Full Text Available This paper examines the effects on specific pathogen-free (SPF chicks when avian metapneumovirus (aMPV and Newcastle disease virus (NDV La Sota strain vaccines are co-administered. Day-old SPF chicks were divided into five groups. The first group was inoculated with sterile water (SW and the rest of the groups were inoculated with live NDV vaccine VG/GA by the oculo-oral route. At 21 days-old, the unvaccinated chicks were again inoculated with SW. The four VG/GA-vaccinated groups were further inoculated with (i SW, (ii live aMPV vaccine, (iii live NDV La Sota, or (iv combined live NDV La Sota and live aMPV, respectively. Chicks were monitored for post-vaccination reactions and oropharyngeal swabs were collected for vaccines detection. Blood samples were collected to detect aMPV ELISA and NDV haemagglutination-inhibition antibodies. Twenty-one days following the second vaccination, six chicks from each group were challenged with virulent NDV or aMPV respectively. Chicks were monitored for clinical signs and mortality and oropharyngeal swabs collected for aMPV detection. Results showed that, when challenged with a virulent aMPV, both chicks previously vaccinated with VG/GA and subsequently given aMPV vaccine singly or in combination with La Sota were equally protected against clinical signs. Chicks that were vaccinated against NDV either once with VG/GA or followed by La Sota (singly or in combination with aMPV were fully protected when challenged with velogenic NDV. We concluded that simultaneous administration of live aMPV and NDV La Sota vaccines have no adverse effects on protection conferred by either live vaccine.

The project also obtained feedback from all relevant stakeholders. Evaluation was carried out by an international visual arts research advisor and an independent observer from the field of suicide research. Results: Outputs included an arts-science mediated exhibition with reference to elevated Irish Traveller suicide rates. Digital online learning materials about suicide and its aftermath among Irish Travellers were also produced. The project reached its target audience, with a high level of engagement from members of the Travelling Community. Discussion: The Lived Lives methodology navigated the societal barriers of stigma and silence to foster communication and engagement, working with cultural values, consistent

Current technologies allow the generation of artificial DNA molecules and/or the ability to alter the DNA sequences of existing DNA molecules. With a careful coding scheme and arrangement, it is possible to encode important information as an artificial DNA strand and store it in a living host safely and permanently. This inventive technology can be used to identify origins and protect R&D investments. It can also be used in environmental research to track generations of organisms and observe the ecological impact of pollutants. Today, there are microorganisms that can survive under extreme conditions. As well, it is advantageous to consider multicellular organisms as hosts for stored information. These living organisms can provide as memory housing and protection for stored data or information. The present invention provides well for data storage in a living organism wherein at least one DNA sequence is encoded to represent data and incorporated into a living organism.

Hegde, V; Mason, A; Saliev, T; Smith, F J D; McLean, W H I; Campbell, P A

2012-01-01

Scanning ion conductance microscopy (SICM) is perhaps the least well known technique from the scanning probe microscopy (SPM) family of instruments. As with its more familiar counterpart, atomic force microscopy (AFM), the technique provides high-resolution topographic imaging, with the caveat that target structures must be immersed in a conducting solution so that a controllable ion current may be utilised as the basis for feedback. In operation, this non-contact characteristic of SICM makes it ideal for the study of delicate structures, such as live cells. Moreover, the intrinsic architecture of the instrument, incorporating as it does, a scanned micropipette, lends itself to combination approaches with complementary techniques such as patch-clamp electrophysiology: SICM therefore boasts the capability for both structural and functional imaging. For the present observations, an ICnano S system (Ionscope Ltd., Melbourn, UK) operating in 'hopping mode' was used, with the objective of assessing the instrument's utility for imaging live keratinocytes under physiological buffers. In scans employing cultured HaCaT cells (spontaneously immortalised, human keratinocytes), we compared the qualitative differences of live cells imaged with SICM and AFM, and also with their respective counterparts after chemical fixation in 4% paraformaldehyde. Characteristic surface microvilli were particularly prominent in live cell imaging by SICM. Moreover, time lapse SICM imaging on live cells revealed that changes in the pattern of microvilli could be tracked over time. By comparison, AFM imaging on live cells, even at very low contact forces (< nN), could not routinely image microvilli: rather, an apparently convolved image of the underlying cytoskeleton was instead prevalent. We note that the present incarnation of the commercial instrument falls some way behind the market leading SPMs in terms of technical prowess and scanning speed, however, the intrinsic non-obtrusive nature of

Complex Macromolecular Architectures by Living Cationic Polymerization

KAUST Repository

Alghamdi, Reem D.

2015-05-01

Poly (vinyl ether)-based graft polymers have been synthesized by the combination of living cationic polymerization of vinyl ethers with other living or controlled/ living polymerization techniques (anionic and ATRP). The process involves the synthesis of well-defined homopolymers (PnBVE) and co/terpolymers [PnBVE-b-PCEVE-b-PSiDEGVE (ABC type) and PSiDEGVE-b-PnBVE-b-PSiDEGVE (CAC type)] by sequential living cationic polymerization of n-butyl vinyl ether (nBVE), 2-chloroethyl vinyl ether (CEVE) and tert-butyldimethylsilyl ethylene glycol vinyl ether (SiDEGVE), using mono-functional {[n-butoxyethyl acetate (nBEA)], [1-(2-chloroethoxy) ethyl acetate (CEEA)], [1-(2-(2-(t-butyldimethylsilyloxy)ethoxy) ethoxy) ethyl acetate (SiDEGEA)]} or di-functional [1,4-cyclohexanedimethanol di(1-ethyl acetate) (cHMDEA), (VEMOA)] initiators. The living cationic polymerizations of those monomers were conducted in hexane at -20 0C using Et3Al2Cl3 (catalyst) in the presence of 1 M AcOEt base.[1] The PCEVE segments of the synthesized block terpolymers were then used to react with living macroanions (PS-DPE-Li; poly styrene diphenyl ethylene lithium) to afford graft polymers. The quantitative desilylation of PSiDEGVE segments by n-Bu4N+F- in THF at 0 °C led to graft co- and terpolymers in which the polyalcohol is the outer block. These co-/terpolymers were subsequently subjected to “grafting-from” reactions by atom transfer radical polymerization (ATRP) of styrene to afford more complex macromolecular architectures. The base assisted living cationic polymerization of vinyl ethers were also used to synthesize well-defined α-hydroxyl polyvinylether (PnBVE-OH). The resulting polymers were then modified into an ATRP macro-initiator for the synthesis of well-defined block copolymers (PnBVE-b-PS). Bifunctional PnBVE with terminal malonate groups was also synthesized and used as a precursor for more complex architectures such as H-shaped block copolymer by “grafting-from” or �

Full Text Available There is limited understanding of the experiences of women living with borderline personality disorder. It was therefore decided to discover how women living with this disorder would tell their life story. For the researcher, who worked in a psychotherapy ward where most women were living with borderline personality disorder, the care of these women was of vital importance, as they were less understood by mental health care providers.The research aimed to explore and describe the experiences of women living with borderline personality disorder. A qualitative, explorative, descriptive and contextual study design was used. Data was collected through in-depth phenomenological interviews that focused on the central question, “Tell me your life story”. Eight participants living with borderline personality disorder were interviewed. Tesch's method for data analysis was used (Creswell, 2009:186, along with an independent coder. Measures to ensure trustworthiness and ethical principles were applied throughout the research. From the findings obtained by means of the interviews of women living with borderline personality disorder, it was evident that there were childhood experiences of living in an unsafe space, related to unhealthy family dynamics, boundary violations and educational challenges. They experienced chronic feelings of emptiness in their relationships with theself. They also presented with a pattern of unstable interpersonal relationships and compromised mental health, which was apparent through the early on set of mental problems, emotional upheaval, looking for emotional escape and having different triggerfactors. Lastly, all these women yearned for facilitated mental health.

Compensated intruder-detection systems

Science.gov (United States)

McNeilly, David R.; Miller, William R.

1984-01-01

Intruder-detection systems in which intruder-induced signals are transmitted through a medium also receive spurious signals induced by changes in a climatic condition affecting the medium. To combat this, signals received from the detection medium are converted to a first signal. The system also provides a reference signal proportional to climate-induced changes in the medium. The first signal and the reference signal are combined for generating therefrom an output signal which is insensitive to the climatic changes in the medium. An alarm is energized if the output signal exceeds a preselected value. In one embodiment, an acoustic cable is coupled to a fence to generate a first electrical signal proportional to movements thereof. False alarms resulting from wind-induced movements of the fence (detection medium) are eliminated by providing an anemometer-driven voltage generator to provide a reference voltage proportional to the velocity of wind incident on the fence. An analog divider receives the first electrical signal and the reference signal as its numerator and denominator inputs, respectively, and generates therefrom an output signal which is insensitive to the wind-induced movements in the fence.

Disability is shown to be both a cause and a consequence of poverty. However, relatively little research has investigated the economic cost of living with a disability. This study reports the results of a study on the extra cost of living with disability in Vietnam in 2011. The study was carried out in eight cities/provinces in Vietnam, including Hanoi and Ho Chi Minh cities (two major metropolitan in Vietnam) and six provinces from each of the six socio-economic regions in Vietnam. Costs are estimated using the standard of living approach whereby the difference in incomes between people with disability and those without disability for a given standard of living serves as a proxy for the cost of living with disability. The extra cost of living with disability in Vietnam accounted for about 8.8-9.5% of annual household income, or valued about US$200-218. Communication difficulty was shown to result in highest additional cost of living with disability and self-care difficulty was shown to lead to the lowest levels of extra of living cost. The extra cost of living with disability increased as people had more severe impairment. Interventions to promote the economic security of livelihood for people with disabilities are needed.

Surface display of biomolecules on live cells offers new opportunities to treat human diseases and perform basic studies. Existing methods are primarily focused on monovalent functionalization, that is, the display of single biomolecules across the cell surface. Here we show that the surface of live cells can be functionalized to display polyvalent biomolecular structures through two-step reactions under physiological conditions. This polyvalent functionalization enables the cell surface to recognize the microenvironment one order of magnitude more effectively than with monovalent functionalization. Thus, polyvalent display of biomolecules on live cells holds great potential for various biological and biomedical applications. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

Living donor kidney transplantation has several advantages for patients with end-stage renal disease. However, many patients are reluctant to pursue this treatment option, preferring instead to wait for a deceased donor organ. To examine predictors of patients' willingness to talk to others about living kidney donation. One hundred thirty-two adult patients awaiting kidney transplantation who were enrolled in a randomized trial examining the effectiveness of education on rates of live donor kidney transplantation completed a baseline rating of their willingness to talk to others about living kidney donation. Also, patients completed measures of knowledge and concerns about living donation and a rating of perceived health. Slightly more than half the patients (56.1%) had low willingness to talk to others about living donation. The following variables were associated with higher willingness to talk to others: white race (odds ratio, 3.31; confidence interval, 1.7-7.4), college education (odds ratio, 3.43, confidence interval, 2.0-5.6), fewer concerns about living donor kidney transplantation (odds ratio, 0.31; confidence interval, 0.2-0.6), and less favorable perceptions of their current health status (odds ratio, 4.31; confidence interval, 2.6-7.6). White race, more education, less concern about living donor kidney transplantation, and poorer perceived health are associated with greater willingness to talk to others about living kidney donation. These findings have important implications for educating patients about living donor kidney transplantation.

Swaps and Chains and Vouchers, Oh My!: Evaluating How Saving More Lives Impacts the Equitable Allocation of Live Donor Kidneys.

Science.gov (United States)

Tenenbaum, Evelyn M

2018-03-01

Live kidney donation involves a delicate balance between saving the most lives possible and maintaining a transplant system that is fair to the many thousands of patients on the transplant waiting list. Federal law and regulations require that kidney allocation be equitable, but the pressure to save patients subject to ever-lengthening waiting times for a transplant has been swinging the balance toward optimizing utility at the expense of justice. This article traces the progression of innovations created to make optimum use of a patient's own live donors. It starts with the simplest - direct donation by family members - and ends with voucher donations, a very recent and unique innovation because the donor can donate 20 or more years before the intended recipient is expected to need a kidney. In return for the donation, the intended recipient receives a voucher that can be redeemed for a live kidney when it is needed. Other innovations that are discussed include kidney exchanges and list paired donation, which are used to facilitate donor swaps when donor/recipient pairs have incompatible blood types. The discussion of each new innovation shows how the equity issues build on each other and how, with each new innovation, it becomes progressively harder to find an acceptable balance between utility and justice. The article culminates with an analysis of two recent allocation methods that have the potential to save many additional lives, but also affirmatively harm some patients on the deceased donor waiting list by increasing their waiting time for a life-saving kidney. The article concludes that saving additional lives does not justify harming patients on the waiting list unless that harm can be minimized. It also proposes solutions to minimize the harm so these new innovations can equitably perform their intended function of stimulating additional transplants and extending the lives of many transplant patients.

Living in history and living by the cultural life script: How older Germans date their autobiographical memories.

Science.gov (United States)

Bohn, Annette; Habermas, Tilmann

2016-01-01

This study examines predictions from two theories on the organisation of autobiographical memory: Cultural Life Script Theory which conceptualises the organisation of autobiographical memory by cultural schemata, and Transition Theory which proposes that people organise their memories in relation to personal events that changed the fabric of their daily lives, or in relation to negative collective public transitions, called the Living-in-History effect. Predictions from both theories were tested in forty-eight-old Germans from Berlin and Northern Germany. We tested whether the Living-in-History effect exists for both negative (the Second World War) and positive (Fall of Berlin Wall) collectively experienced events, and whether cultural life script events serve as a prominent strategy to date personal memories. Results showed a powerful, long-lasting Living-in History effect for the negative, but not the positive event. Berlin participants dated 26% of their memories in relation to the Second World War. Supporting cultural life script theory, life script events were frequently used to date personal memories. This provides evidence that people use a combination of culturally transmitted knowledge and knowledge based on personal experience to navigate through their autobiographical memories, and that experiencing war has a lasting impact on the organisation of autobiographical memories across the life span.

The increased risk for poor physical and mental health outcomes for older parents in Mexico who have an adult child living in the United States may contribute to an increased risk for cognitive impairment in this population. The objective of this study was to examine if older adults in Mexico who have one or more adult children living in the United States are more or less likely to develop cognitive impairment over an 11-year period compared to older adults who do not have any adult children living in the United States. Data for this study came from Wave I (2001) and Wave III (2012) of the Mexican Health and Aging Study. The final sample included 2609 participants aged 60 and over who were not cognitively impaired in 2001 and had one or more adult children (age ≥15). Participants were matched using a propensity score that was estimated with a multivariable logistic regression model that included sociodemographic characteristics and migration history of the older parents. Having one or more adult children living in the United States is associated with lower socioeconomic status and higher number of depressive symptoms, but greater social engagement for older parents living in Mexico. No significant differences in the odds for developing cognitive impairment according to having one or more adult children living in the United States were detected. In summary, having one or more adult children living in the United States was associated with characteristics that may increase and decrease the risk for cognitive impairment. This may contribute to the non-significant relationship between migration status of adult children and likelihood for cognitive impairment for older parents living in Mexico.

Teke, T [BC Cancer Agency, Centre for the Southern Interior, Kelowna, BC (Canada)

2016-06-15

Purpose: To present and validate a set of quality control tests for trajectory treatment delivery using synchronized dynamic couch (translation and rotation), MLC and collimator motion. Methods: The quality control tests are based on the Picket fence test, which consist of 5 narrow band 2mm width spaced at 2.5cm intervals, and adds progressively synchronized dynamic motions. The tests were exposed on GafChromic EBT3 films. The first test is a regular (no motion and MLC static while beam is on) Picket Fence test used as baseline. The second test includes simultaneous collimator and couch rotation, each stripe corresponding to a different rotation speed. Errors in these tests were introduced (0.5 degree and 1 degree error in rotation synchronization) to assess the error sensitivity of this test. The second test is similar to the regular Picket Fence but now including dynamic MLC motion and couch translation (including acceleration during delivery) while the beam is on. Finally in the third test, which is a combination of the first and second test, the Picket Fence pattern is delivered using synchronized collimator and couch rotation and synchronized dynamic MLC and couch translation including acceleration. Films were analyzed with FilmQA Pro. Results: The distance between the peaks in the dose profile where measured (18.5cm away from the isocentre in the inplane direction where non synchronized rotation would have the largest effect) and compared to the regular Picket Fence tests. For well synchronized motions distances between peaks where between 24.9–25.4 mm identical to the regular Picket Fence test. This range increased to 24.4–26.4mm and 23.4–26.4mm for 0.5 degree and 1 degree error respectively. The amplitude also decreased up to 15% when errors are introduced. Conclusion: We demonstrated that the Roucoulette tests can be used as a quality control tests for trajectory treatment delivery using synchronized dynamic motion.

Living materials, which are composites of living cells residing in a polymeric matrix, are designed to utilize the innate functionalities of the cells to address a broad range of applications such as fermentation and biosensing. Herein, we demonstrate the additive manufacturing of catalytically active living materials (AMCALM) for continuous fermentation. A multi-stimuli-responsive yeast-laden hydrogel ink, based on F127-dimethacrylate, was developed and printed using a direct-write 3D printer. The reversible stimuli-responsive behaviors of the polymer hydrogel inks to temperature and pressure are critical, as they enabled the facile incorporation of yeast cells and subsequent fabrication of 3D lattice constructs. Subsequent photo-cross-linking of the printed polymer hydrogel afforded a robust elastic material. These yeast-laden living materials were metabolically active in the fermentation of glucose into ethanol for 2 weeks in a continuous batch process without significant reduction in efficiency (∼90% yield of ethanol). This cell immobilization platform may potentially be applicable toward other genetically modified yeast strains to produce other high-value chemicals in a continuous biofermentation process.

Nicolosi, S.L.; Rodriguez, M.A.

1994-04-01

The objective of the Live-Fire Range Risk Analysis Report (RAR) is to provide an authorization basis for operation as required by DOE 5480.16. The existing Live-Fire Range does not have a safety analysis-related authorization basis. EG&G Rocky Flats, Inc. has worked with DOE and its representatives to develop a format and content description for development of an RAR for the Live-Fire Range. Development of the RAR is closely aligned with development of the design for a baffle system to control risks from errant projectiles. DOE 5480.16 requires either an RAR or a safety analysis report (SAR) for live-fire ranges. An RAR rather than a SAR was selected in order to gain flexibility to more closely address the safety analysis and conduct of operation needs for a live-fire range in a cost-effective manner.

OpenAIRE

Thomas von Brasch

2013-01-01

The standard cost-of-living index hinges on the assumption that there is free trade. Applying it to situations where trade barriers are present yields biased results with respect to a true cost-of-living index. Import price indices are particularly vulnerable to this bias since many of the goods included in these indices are characterised by either explicit or implicit trade barriers. In this article I generalise the cost-of-living index to also allow for barriers to trade in the form of quan...

Dynamical real numbers and living systems

Datta, Dhurjati Prasad

2004-01-01

Recently uncovered second derivative discontinuous solutions of the simplest linear ordinary differential equation define not only an nonstandard extension of the framework of the ordinary calculus, but also provide a dynamical representation of the ordinary real number system. Every real number can be visualized as a living cell-like structure, endowed with a definite evolutionary arrow. We discuss the relevance of this extended calculus in the study of living systems. We also present an intelligent version of the Newton's first law of motion

Living an unstable everyday life while attempting to perform normality - the meaning of living as an alcohol-dependent woman.

2013-02-01

To illuminate the meaning of living with alcohol dependency as a woman. The number of women suffering from alcohol dependency is increasing. Today there are shortcomings in knowledge about the lived experiences of being a woman with alcohol dependency; knowledge which might be of importance for meeting these women's specific needs of care. The study has a qualitative design. Fourteen women with alcohol dependency participated in open in-depth interviews. Data were analysed according to a phenomenological-hermeneutic method, and interpreted by help from gender and caring perspectives as well as results from previous research of alcohol dependency. In relation to the women's senses of well-being, four main gender formations were found; An unstable self involving continual and rapid swings between emotional and bodily reactions. Ambivalence - meaning ambiguous feelings towards themselves as human beings and how they lead their lives. Introspectiveness - involving reflections, pondering and being introverted. Attempts to perform normality - covering - dealing with life through various strategies and facades to live up to the expectations of how to behave as a woman. Living with alcohol dependency as a woman constitutes of a rapid shifting everyday life resulting in senses of alienation as well as private introspection leading to self-degradation, and to a lesser extent meaningfulness and hope. It also constitutes of managing to perform normality. When supporting women with alcohol dependency towards wellbeing, professionals need to work towards approaching the woman's inner thoughts, share them and reflect over them together. To support these women to find balance in life, caregivers need to cooperate with the women to find out how best to live a life adjusted to the woman's abilities and wishes. © 2012 Blackwell Publishing Ltd.

Assessing resolution in live cell structured illumination microscopy

Science.gov (United States)

Pospíšil, Jakub; Fliegel, Karel; Klíma, Miloš

2017-12-01

Structured Illumination Microscopy (SIM) is a powerful super-resolution technique, which is able to enhance the resolution of optical microscope beyond the Abbe diffraction limit. In the last decade, numerous SIM methods that achieve the resolution of 100 nm in the lateral dimension have been developed. The SIM setups with new high-speed cameras and illumination pattern generators allow rapid acquisition of the live specimen. Therefore, SIM is widely used for investigation of the live structures in molecular and live cell biology. Quantitative evaluation of resolution enhancement in a real sample is essential to describe the efficiency of super-resolution microscopy technique. However, measuring the resolution of a live cell sample is a challenging task. Based on our experimental findings, the widely used Fourier ring correlation (FRC) method does not seem to be well suited for measuring the resolution of SIM live cell video sequences. Therefore, the resolution assessing methods based on Fourier spectrum analysis are often used. We introduce a measure based on circular average power spectral density (PSDca) estimated from a single SIM image (one video frame). PSDca describes the distribution of the power of a signal with respect to its spatial frequency. Spatial resolution corresponds to the cut-off frequency in Fourier space. In order to estimate the cut-off frequency from a noisy signal, we use a spectral subtraction method for noise suppression. In the future, this resolution assessment approach might prove useful also for single-molecule localization microscopy (SMLM) live cell imaging.

Blurriness in Live Forensics: An Introduction

Science.gov (United States)

Savoldi, Antonio; Gubian, Paolo

The Live Forensics discipline aims at answering basic questions related to a digital crime, which usually involves a computer-based system. The investigation should be carried out with the very goal to establish which processes were running, when they were started and by whom, what specific activities those processes were doing and the state of active network connections. Besides, a set of tools needs to be launched on the running system by altering, as a consequence of the Locard’s exchange principle [2], the system’s memory. All the methodologies for the live forensics field proposed until now have a basic, albeit important, weakness, which is the inability to quantify the perturbation, or blurriness, of the system’s memory of the investigated computer. This is the very last goal of this paper: to provide a set of guidelines which can be effectively used for measuring the uncertainty of the collected volatile memory on a live system being investigated.

Accelerator mass spectrometry (AMS) was developed over the past 15 years as an essential tool for detecting long-lived, cosmogenic radio-isotopes in the earth and space sciences. We apply this technology to the measurement of chemical kinetics, primarily in biomedical systems, which had heretofore employed short-lived isotopes and/or long counting times to quantify radio-isotopic labels. AMS provides detection efficiencies of ∼ 1%, 10 3 to 10 6 better than decay-counting. Long-lived isotopes are used and detected with AMS at concentrations which reduce sample size, chemical dose, radiation safety hazards and radiolysis. We measure 3 H, 7,1O Be, 14 C, 26 Al, 36 CI, 41 Ca and 129 I, but most of our current program uses 14 C. Initial experiments involved research on the genotoxicity of mutagens in cooked foods and reversible binding of compounds to antibodies. Through collaborations, we apply AMS detection to research in carcinogenesis, pharmacokinetics of toxins, elemental metabolism, distribution of topical medications and nutrition

De, Abhijit; Gambhir, Sanjiv Sam

2005-12-01

This study demonstrates a significant advancement of imaging of a distance-dependent physical process, known as the bioluminescent resonance energy transfer (BRET2) signal in living subjects, by using a cooled charge-coupled device (CCD) camera. A CCD camera-based spectral imaging strategy enables simultaneous visualization and quantitation of BRET signal from live cells and cells implanted in living mice. We used the BRET2 system, which utilizes Renilla luciferase (hRluc) protein and its substrate DeepBlueC (DBC) as an energy donor and a mutant green fluorescent protein (GFP2) as the acceptor. To accomplish this objective in this proof-of-principle study, the donor and acceptor proteins were fused to FKBP12 and FRB, respectively, which are known to interact only in the presence of the small molecule mediator rapamycin. Mammalian cells expressing these fusion constructs were imaged using a cooled-CCD camera either directly from culture dishes or by implanting them into mice. By comparing the emission photon yields in the presence and absence of rapamycin, the specific BRET signal was determined. The CCD imaging approach of BRET signal is particularly appealing due to its capacity to seamlessly bridge the gap between in vitro and in vivo studies. This work validates BRET as a powerful tool for interrogating and observing protein-protein interactions directly at limited depths in living mice.

Despite the increasing challenges associated with urbanization and the aging population, urban life appears to be positive in many ways for urban dwellers. However, the manner in which older people live in urban settings and how this influences their ability to take care of themselves should be considered important knowledge for health professionals and politicians to acquire. The aim of this study was to describe the lived experiences of self-care and features that may influence health and self-care among older urban home-dwelling individuals who are physically active.Methods: Ten subjects, three women and seven men, who were aged 65–82 years and identified to be physically active, were interviewed. The interviews were recorded, transcribed verbatim, and analyzed according to the descriptive phenomenological method devised by Giorgi.Results: Our findings showed beneficial self-care. The participants lived active everyday lives and were frequently physically active. They were part of a supportive, inclusive, and promoting fellowship, and they had the opportunity to travel. They utilized their competence and experienced making themselves useful. It was a privilege to be part of a family life as a husband, wife, parent, and/or a grandparent. They

Cadaveric liver transplantation (5-year survival >80%) represents the standard of care for end-stage liver disease (ESLD). Because the demand for cadaveric organs exceeds their availability, living-donor liver transplantation has gained increasing acceptance. Our aim was to assess the marginal cost-effectiveness of cadaveric and living-donor orthotopic liver transplantation (OLT) in adults with ESLD. Using a Markov model, outcomes and costs of ESLD treated (1) conservatively, (2) with cadaveric OLT alone, and (3) with cadaveric OLT or living-donor OLT were computed. The model was validated with published data. The case-based scenario consisted of data on all 15 ESLD patients currently on our waiting list (3 women, 12 men; median age, 48 years [range, 33-59 years]) and on the outcome of all OLT performed for ESLD at our institution since 1995 (n=51; actuarial 5-year survival 93%). Living-donor OLT was allowed in 15% during the first year of listing; fulminant hepatic failure and hepatocellular carcinoma were excluded. Cadaveric OLT gained on average 6.2 quality-adjusted life-years (QALYs) per patient compared with conservative treatment, living-donor OLT, an additional 1.3 QALYs compared with cadaveric OLT alone. Marginal cost-effectiveness of a program with cadaveric OLT alone and a program with cadaveric and living-donor OLT combined were similar (E 22,451 and E 23,530 per QALY gained). Results were sensitive to recipient age and postoperative survival rate. Offering living-donor OLT in addition to cadaveric OLT improves survival at costs comparable to accepted therapies in medicine. Cadaveric OLT and living-donor OLT are cost-effective.

Ge, Li; Wikby, Kerstin; Rask, Mikael

2017-11-28

To explore the lived experience of women with gestational diabetes mellitus (GDM) living in China in order to add knowledge about how the Chinese women suffer from GDM. A qualitative interpretive interview study. Data were collected with a snowball sampling technique. Phenomenological hermeneutics was used as the analysis method based on Ricoeur's phenomenological hermeneutical interpretation theory. The study was performed at the participants' work places, or at the obstetric clinics or wards at two provincial hospitals and one municipal hospital in the southeast of China. Inclusion criteria were age ≥18 years, diagnosis of GDM without other pregnancy complications, in 34th gestational weeks-postpartum 4th weeks and speaking Mandarin Chinese without speech impediment. 62 women, who met the inclusion criteria, took part in the study. The lived experience of the women with GDM living in China was formulated into a main theme: 'longing for caring care'. The main theme was derived from four themes: being stricken by GDM, wishing to receive caring GDM care, being left alone to struggle with GDM and trying to adjust and adapt to life with GDM. The eagerness for caring care in China was highlighted. The lack of caring care could be one of the possible reasons why the professional-patient relations were deteriorating in China. It could be useful for health providers and health policymakers to receive education and training about caring care. Using the health metaphor of balance and 'patient participation' and 'patient-centred' approaches may benefit women with GDM and thus improve the quality of care in China. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Graphical abstract: TOC After a first decay common to all electrocatalysts, only NC Por-0.8 -1150 Ar + NH3 shows an improvement in durability attributable to a decrease in water flooding its catalytic sites, particularly those located in micropores. - Abstract: Fe/N/C type catalysts have been produced by ballmilling ZIF-8 (a metal-organic-framework) and a chloroiron-tetramethoxyporphyrin (ClFeTMPP). The resulting material was first pyrolyzed in Ar at temperatures ranging from 850 to 1150 °C, then in NH 3 at 950 °C in order to produce two series of catalysts: the Ar and the Ar + NH 3 ones. They were labeled NC Por-x-T Ar or NC Por-x-T Ar + NH 3 , where x is the nominal Fe loading in wt% and T is the temperature of the first pyrolysis in Ar. At 80 °C in H 2 /O 2 fuel cell, the most active and performing catalyst is NC Por-0.8-1050 Ar + NH 3 . All NC Por-0.8-T Ar + NH 3 catalysts with T comprised between 850 and 1050 °C display the same instability behavior. The only catalyst showing an improvement in durability is NC Por-0.8-1150 Ar + NH 3 . It is proposed that the drastic change in durability upon increasing the first pyrolysis temperature, from 1050 to 1150 °C in Ar, is attributable to an important decrease in the heteroatom content (a drop of 32% for both N and O atoms) of the catalyst upon graphitization, reducing the hydrophilic character of its carbonaceous support and decreasing the possibility of water flooding its catalytic sites, particularly the sites located in micropores

The first time when we tossed this terminology seven years back, we thought reducing complexities in human life. Today we believe it more. However, smart living for all complicates the technological need further. As by all, we mean any age group, any academic background and any financial condition. Although electronics are powerful today and have enabled our digital world, many as of today have not experienced that progress. Going forward while we realize more and more electronics in our daily life, the most important question would be how. Here we show, a heterogeneous integration approach to integrate low-cost high performance interactive electronic system which are physically compliant. We are redesigning electronics to redefine its purposes to reconfigure life for all to enable smart living.

This study examined and compared the physical health status, self-esteem, family support and health-promoting behaviours between aged living alone and the aged living with family. As the Korean population ages, the number of older people living alone is steadily rising. Previous studies have been conducted to define the factors affecting the health of older people. However, research studies focused on the impact of family support, which potentially affects the overall health of older people, have been rarely conducted. This was a comparative descriptive design. The survey included a set of four questionnaires. All measures were self-administered. In the data analysis, descriptive statistics were used to analyse the demographic characteristics. The Chi-square test and independent t-test were used to examine the differences between the aged living alone and the aged living with family.

In this paper, we seek to re-conceptualize the ethical framework through which ethicists and medical professionals view the practice of live kidney donations. The ethics of organ donation has been understood primarily within the framework of individual rights and impartiality, but we show that the ethic of care captures the moral situation of live kidney donations in a more coherent and comprehensive way, and offers guidance for practitioners that is more attentive to the actual moral transactions among donors and recipients. A final section offers guidelines for the practice of live kidney transplants that emerge from an ethic of care.

Changes in living arrangements and mortality among older people in China

Directory of Open Access Journals (Sweden)

Zhixin Feng

2017-12-01

Full Text Available Living arrangements in later life are dynamic, with changes associated with life events such as widowhood or moves into an institution. Previous research has found particular changes in living arrangements to be associated with an elevated risk of mortality. However, research in this area within the context of China is limited, despite China being home to the world's largest population of older people. This study investigates the impact of changes in living arrangements on older persons’ survival using the Chinese Longitudinal Healthy Longevity Survey from 2002 to 2011. The original sample was 16,064 in 2002, and this study includes 6191 individuals who survived in 2005 and had complete information of track record in later waves. Changes in living arrangements are examined between 2002 and 2005. Cox-proportional hazards models are then used to investigate the association between the dynamics of living arrangements and respondents’ survival status from 2005 to 2011 . Results show that men and women who lived in an institution in both 2002 and 2005, or who moved into an institution from living with family faced a greater risk of dying compared to those continuing to live with family. By contrast, continuing to live with family or alone, or moving between living with family and living alone, were not associated with an increased mortality risk, although there were some differences by gender. The institutional care sector in China is still in its infancy, with provision based on ability to pay market fees rather than need associated with age-related function impairment. The findings show that living in, or moving into, an institution is associated with a high mortality risk therefore requires further investigation in the context of a rapidly changing Chinese society.

Identity related to living situation in six individuals with congenital quadriplegia.

Science.gov (United States)

Robey, Kenneth L

2008-01-01

This study was a preliminary examination of structural aspects of identity, particularly identity associated with living situation, in individuals who have quadriplegia due to cerebral palsy. A hierarchical classes algorithm (HICLAS) was used to construct idiographic 'identity structure' models for three individuals who are living in an inpatient hospital setting and for three individuals living in community-based group residences. Indices derived from the models indicate that the identity 'myself as one who has a disability' was structurally superordinate (i.e., resided at a high hierarchical level) for all six participants, suggesting a high level of importance of this identity in participants' sense of self. The models also indicate that while identity associated with one's particular living situation was superordinate for persons living in the hospital, it was not for persons living in community residences. While conclusions based on this small sample are necessarily limited, the data suggest that identity associated with living situation might differ in structural centrality, and presumably subjective importance, for persons living in inpatient versus community-based settings.

Day of surgery admission for the elective surgical in-patient: successful implementation of the Elective Surgery Programme.

LENUS (Irish Health Repository)

Concannon, E S

2012-09-11

BACKGROUND AND AIMS: The aim of this prospective cross-sectional study was to determine the impact of (1) ring fencing in-patient general surgical beds and (2) introducing a pre-operative assessment clinic (PAC) on the day of surgery admission (DOSA) rate in a single Irish institution. The secondary aim was to analyse the impact of an increased rate of DOSA on cost efficiency and patient satisfaction. METHODS: An 18-month period was examined following ring-fencing of elective and emergency surgical beds. A PAC was established during the study period. Prospectively collected data pertaining to all surgical admissions were retrieved using patient administration system software (Powerterm Pro, Eircom Software) and a database of performance information from Irish Public Health Services (HealthStat). RESULTS: Ring-fencing and PAC establishment was associated with a significant increase in the overall DOSA rate from 56 to 85 %, surpassing the national target rate of DOSA (75 %). Data relating specifically to general surgery admissions mirrored this increase in DOSA rate from a median of 5 patients per month, before the advent of ring-fencing and PAC, to 42 patients per month (p < 0.0387). 100 patient surveys demonstrated high levels of satisfaction with DOSA, with a preference compared to admission one night pre-operatively. Cost analysis demonstrated overall savings of 340,370 Euro from this change in practice. CONCLUSION: The present study supports the practice of DOSA through the introduction of ring-fenced surgical beds and PAC. This has been shown to improve hospital resource utilisation and streamline surgical service provision in these economically challenging times.

The relationship of the elderly toward their home and living environment

Full Text Available Housing is a basic human good and right. It plays a versatile role, allowing people to fulfil a number of needs, and it is not limited only to one’s immediate living space, but also includes an individual’s wider living environment. People’s relationship toward housing and their living environment changes over the course of their lives. Especially in old age, housing becomes more important. Research shows that the elderly want to remain in their home environments as long as possible because they are closely attached to them. In order to determine whether these findings also apply to Slovenia, this article analyses how attached the elderly in Slovenia are to their homes and wider living environment and how satisfied they are with living there. The elderly’s views were obtained with a survey, and a statistical analysis was carried out using SPSS software, based on the calculation of various statistical correlation tests. The analysis confirmed the assumption that the Slovenian elderly are also very attached to their homes or home environments and are satisfied with living there. In addition, the analysis showed some differences among the elderly in this regard depending on their age, where they live and how long they have been living in their current homes.

Between Sumak Kawsay and Institutional Good Living. The social discourses of Good Living in rural areas of Southern Ecuador

Full Text Available The strategies of building alternative measures of development have been established from a disconnected approach of very significant elements such as the legitimation or the dynamics of change of capitalism. In this research we study a particular case for a proposal of measuring development from the concept of Sumak Kawsay. This concept brings together very special properties which, although characterized by the same criteria as its alternatives (multidimensionality, segmentation, balance and subjectivity, resort to the novel use of a myth, that legitimizes communitary ways of living that are different to the most widespread lifestyles. This paper presents a discourse analysis of the conceptions about Good Living that can be extracted from the texts of interviews and other group dynamics carried out in the peasant communities of Nabón, a rural canton of the South of Ecuador. The analysis results a relational structure in which the limits and contents of an adaptive or hybrid discourse are defined, which is the product of the interaction between two opposing discourses: Sumak Kawsay (community and traditional and goverment’s Institutional Good Living (societal and modern. This interaction allows to expose and to explain the set of contradictions detected; and the emergence of new categories that establish the limits of this adaptive discourse on Good Living: bad living, good dying or quality of life. In this way, the positions of the internal fractures of the populations are explained, as well as their strategies for subsistence and negotiation with government authorities.

2004-08-01

Biometrics is a rapidly developing technology that is to identify a person based on his or her physiological or behavioral characteristics. To ensure the correction of authentication, the biometric system must be able to detect and reject the use of a copy of a biometric instead of the live biometric. This function is usually termed "liveness detection". This paper describes a new method for live face detection. Using structure and movement information of live face, an effective live face detection algorithm is presented. Compared to existing approaches, which concentrate on the measurement of 3D depth information, this method is based on the analysis of Fourier spectra of a single face image or face image sequences. Experimental results show that the proposed method has an encouraging performance.

It has been consistently shown that words representing living things are better remembered than words representing nonliving things, yet the underlying cognitive and neural mechanisms have not been clearly elucidated. The present study used both univariate and multivariate pattern analyses to examine the hypotheses that living words are better remembered because (1) they draw more attention and/or (2) they share more overlapping semantic features. Subjects were asked to study a list of living and nonliving words during a semantic judgment task. An unexpected recognition test was administered 30 min later. We found that subjects recognized significantly more living words than nonliving words. Results supported the overlapping semantic feature hypothesis by showing that (a) semantic ratings showed greater semantic similarity for living words than for nonliving words, (b) there was also significantly greater neural global pattern similarity (nGPS) for living words than for nonliving words in the posterior portion of left parahippocampus (LpPHG), (c) the nGPS in the LpPHG reflected the rated semantic similarity, and also mediated the memory differences between two semantic categories, and (d) greater univariate activation was found for living words than for nonliving words in the left hippocampus (LHIP), which mediated the better memory performance for living words and might reflect greater semantic context binding. In contrast, although living words were processed faster and elicited a stronger activity in the dorsal attention network, these differences did not mediate the animacy effect in memory. Taken together, our results provide strong support to the overlapping semantic features hypothesis, and emphasize the important role of semantic organization in episodic memory encoding.

Living Shorelines: Coastal Resilience with a Blue Carbon Benefit.

Directory of Open Access Journals (Sweden)

Jenny L Davis

Full Text Available Living shorelines are a type of estuarine shoreline erosion control that incorporates native vegetation and preserves native habitats. Because they provide the ecosystem services associated with natural coastal wetlands while also increasing shoreline resilience, living shorelines are part of the natural and hybrid infrastructure approach to coastal resiliency. Marshes created as living shorelines are typically narrow (< 30 m fringing marshes with sandy substrates that are well flushed by tides. These characteristics distinguish living shorelines from the larger meadow marshes in which most of the current knowledge about created marshes was developed. The value of living shorelines for providing both erosion control and habitat for estuarine organisms has been documented but their capacity for carbon sequestration has not. We measured carbon sequestration rates in living shorelines and sandy transplanted Spartina alterniflora marshes in the Newport River Estuary, North Carolina. The marshes sampled here range in age from 12 to 38 years and represent a continuum of soil development. Carbon sequestration rates ranged from 58 to 283 g C m-2 yr-1 and decreased with marsh age. The pattern of lower sequestration rates in older marshes is hypothesized to be the result of a relative enrichment of labile organic matter in younger sites and illustrates the importance of choosing mature marshes for determination of long-term carbon sequestration potential. The data presented here are within the range of published carbon sequestration rates for S. alterniflora marshes and suggest that wide-scale use of the living shoreline approach to shoreline management may come with a substantial carbon benefit.

Numerical calculation on a two-step subdiffusion behavior of lateral protein movement in plasma membranes

Science.gov (United States)

Sumi, Tomonari; Okumoto, Atsushi; Goto, Hitoshi; Sekino, Hideo

2017-10-01

A two-step subdiffusion behavior of lateral movement of transmembrane proteins in plasma membranes has been observed by using single-molecule experiments. A nested double-compartment model where large compartments are divided into several smaller ones has been proposed in order to explain this observation. These compartments are considered to be delimited by membrane-skeleton "fences" and membrane-protein "pickets" bound to the fences. We perform numerical simulations of a master equation using a simple two-dimensional lattice model to investigate the heterogeneous diffusion dynamics behavior of transmembrane proteins within plasma membranes. We show that the experimentally observed two-step subdiffusion process can be described using fence and picket models combined with decreased local diffusivity of transmembrane proteins in the vicinity of the pickets. This allows us to explain the two-step subdiffusion behavior without explicitly introducing nested double compartments.

The ratio of long-lived to short-lived radon-222 progeny concentrations in ground-level air

International Nuclear Information System (INIS)

Hoetzl, H.; Winkler, R.

1996-01-01

The ratio of 210 Pb air concentration to the short-lived radon ( 222 Rn) decay products concentration at ground level was investigated at a semi-rural location 10 km north of Munich, south Germany, for a period of 11 years (1982-1992). The average ratio from 132 monthly mean values has been found to be (7.5±2.2) x 10 -5 (arithmetic mean±S.D.). While the time series of the short-lived radon daughter concentration exhibit a distinct seasonal pattern with maxima mostly in October of each year, the course of 210 Pb air concentration is characterized by high values from October through February. Consequently, high ratios of 210 Pb to short-lived decay product concentration are often observed in the winter months of December-February. To study the influence of meteorological conditions on this behaviour, 210 Pb and 214 Pb concentrations were measured on a short-term basis with sampling intervals of 2-3 days from October 1991 to November 1992. The air concentrations obtained within those intervals were then correlated with actual meteorological parameters. On the base of this investigation the seasonal behaviour can essentially be explained by the more frequent inversion weather conditions in winter than in the summer months. At the same location, the average ratio of 210 Po to 210 Pb concentration in ground level air has been found to be 0.079 from 459 weakly mean values between 1976 and 1985. Hence, the corresponding average ratios of the short-lived radon daughters (EEC) to 210 Pb and 210 Po, were 1:7.5x10 -5 and 1:0.6 x 10 -5 , respectively

An Ultralightweight and Living Legged Robot.

In this study, we describe the most ultralightweight living legged robot to date that makes it a strong candidate for a search and rescue mission. The robot is a living beetle with a wireless electronic backpack stimulator mounted on its thorax. Inheriting from the living insect, the robot employs a compliant body made of soft actuators, rigid exoskeletons, and flexure hinges. Such structure would allow the robot to easily adapt to any complex terrain due to the benefit of soft interface, self-balance, and self-adaptation of the insect without any complex controller. The antenna stimulation enables the robot to perform not only left/right turning but also backward walking and even cessation of walking. We were also able to grade the turning and backward walking speeds by changing the stimulation frequency. The power required to drive the robot is low as the power consumption of the antenna stimulation is in the order of hundreds of microwatts. In contrast to the traditional legged robots, this robot is of low cost, easy to construct, simple to control, and has ultralow power consumption.

SIGNATURES OF LONG-LIVED SPIRAL PATTERNS

International Nuclear Information System (INIS)

Martínez-García, Eric E.; González-Lópezlira, Rosa A.

2013-01-01

Azimuthal age/color gradients across spiral arms are a signature of long-lived spirals. From a sample of 19 normal (or weakly barred) spirals where we have previously found azimuthal age/color gradient candidates, 13 objects were further selected if a two-armed grand-design pattern survived in a surface density stellar mass map. Mass maps were obtained from optical and near-infrared imaging, by comparison with a Monte Carlo library of stellar population synthesis models that allowed us to obtain the mass-to-light ratio in the J band, (M/L) J , as a function of (g – i) versus (i – J) color. The selected spirals were analyzed with Fourier methods in search of other signatures of long-lived modes related to the gradients, such as the gradient divergence toward corotation, and the behavior of the phase angle of the two-armed spiral in different wavebands, as expected from theory. The results show additional signatures of long-lived spirals in at least 50% of the objects.

Conferences and meetings bring together thousands of doctors from diverse locations. However, the traveling, accommodation, and arrangement of venues for conferences and meetings are expensive and a lot of time needs to be devoted to these logistics. The purpose of this article was to present our own virtual live conference experience using web conferencing and to briefly outline the basics and advantages of this technology in organization of healthcare conferences. Web conferencing technology was used to organize an international bariatric surgery conference, allowing a large number of attendees to participate and interact from wherever they were, using merely an Internet connection with a video player on their personal computers, laptops, or smartphones. A virtual live conference saves a lot of time and cost and simplifies the logistics needed to organize a learning conference with worldwide participation. As far as we know, this is the first report of a virtual live conference in healthcare. We see it as the future of organizing experts as well as medical teaching conferences.

WAYS TO IMPROVE THE TRANSPORT OF LIVE FISH

Directory of Open Access Journals (Sweden)

V. Chernik

2014-03-01

Full Text Available Purpose. To calculate the cost of transportation of live fish by various means of transport and to identify ways to improve the efficiency of their transport. Methodology. The studies were conducted using an economic analysis. Findings. Based on the study we estimated the prime cost of live fish delivery, which ranged from 3.7 to 6.5 UAH for 1 km for the delivery of 1 ton depending on the type of vehicle. The main backup to increase the efficiency of the transport is to increase the density of fish. Total economic effect from introduction of a modernized park of transportation of live fish vehicles in Ukraine can be assessed based on the amount of commodity fish and stocking fish. So, last years, enterprises which report their activity in the bodies of state statistics, rear up to 20 000 t of common carp and silver carp annually. Greater part of fish will be sold to the eventual consumer in alive condition and the mean distance where the fish is transported is about 100 km. The economic effect from the decrease of prime price of transportation will make to 2 000 000 UAH per year. In addition, more than 1000 t of rainbow trout is delivered from Western regions of Ukraine at distances greater than 100 km. cost saving during transport of trout will make up to 500 000 UAH per year. Originality. An analysis of the use of different types of vehicles for the transport of live fish has been performed. Practical Value. To ensure the safe transport of live fish it is necessary to use modernized live fish vehicles.
