The impact of result abstracts on task completion time.

This paper examines the impact of web search result abstracts on task completion time. The dataset we analyze comes from a controlled study in which paid participants carry out assigned tasks using a popular search engine. We compare task completion times with the abstracts removed to the task completion times with the abstracts present. We conclude that the removal of the abstracts leads to longer task completion times. The statistical significance of the result verifies that task time is a potentially useful metric for evaluating abstract quality. For comparison, we also have participants carry out the same tasks with the abstracts present but with the first five search results removed. This leads to even longer task completion times, and gives us a reference point for quantifying the value of the search result abstracts relative to the value of the first five search results themselves.
A content analysis of Journal of Library Science in China in 2007–2016

Abstract A content analysis of JLSC’s publications in 2007–2016 was conducted to investigate its publication patterns and research topics. Elements such as article titles, keywords, authors’ affiliations, titles, disciplines, author collaboration and grant-funded projects were coded and examined. Findings indicate that libraries, information services, cataloging and classification, knowledge management and information retrieval were the most frequently discussed topics. Over 50% of the authors were LIS faculty members with librarian practitioners and LIS graduate students each representing about one-quarter of the total authorship. The percentage of case studies was not significant. Over half of the articles resulted from grant-funded projects. Collaborative writing was active.
Employing Kinect for Cognitive-Motor Assessment: A Feasibility Study

This study examined the feasibility of the Microsoft Kinect sensor for assessing mediolateral trunk sway and its associations with cognitive abilities. To this end, young adults and elderlies were sampled and performed various gait and balance tasks under singleand dual-task paradigms. Although reliable, Kinect’s ability to assess cognition through movement was not conclusive. Specifically, the Kinect distinguished between youngand old-adults gait, but not between young-adults with and without attention-deficit-disorder. However, gait under divided-attention and balance in the absence of visual-information interacted and affected performance in the Trail Making Test (TMT). The simple-effects showed that TMT-performance among participants with better stability in the absence of visual information was not affected by increased attentional demands. In contrast, attentional demands ill-affected TMT-performance among those who did not maintain their stability in the absence of visual information. We discuss these findings in terms of interoceptive attention, awareness, and control over movement.
Autoimmune Ovarian Failure

The concept that an autoimmune mechanism is the cause of primary, or premature, ovarian failure in some instances is rapidly gaining support. Data in support of this concept has accumulated in three areas: (1) the association of autoimmune phenomena and premature ovarian failure has been reported in isolated instances; (2) circulating antibodies to the ovary have been demonstrated in sera from women with this disorder; and (3) a lymphocytic infiltrate has been found in ovarian specimens of some patients. Autoimmune diseases have been defined as pathologic processes that are either caused by or associated with an immune response (either cellular or humoral) against the body's own (self) antigens. One of the basic concepts in immunology involves the immunologic differentiation of "self" from "nonself. " The loss of self-recognition in autoimmune phenomena has not been explained, but it is generally agreed that autoimmunity results from a defect in the mechanisms that maintain self-tolerance. Burnet postulated that exposure of mutant immunocompetent cells to autoantigens early in the course of ontogeny results in elimination or inactivation of these mutant cells. The development of autoantibodies later in life was thought to result from the proliferation of these "forbidden clones. " Discoveries more directly relevant to autoimmune endocrine syndromes came first with the histologic description of chronic lymphocytic thyroiditis, by Hashimoto in 1912, followed by the first report nearly a half century later that it was associated with autoantibodies to thyroglobulin. Since then, various individual diseases have been associated with autoantibodies and antigens. ' Relatively recently, ovarian failure has been added to a rapidly growing list of these autoimmune disorders, some of which have been included in a syndrome known as polyglandular failure syndrome. It is this association of premature ovarian failure with autoimmune disorders, together with the findings of circulating antibody to normal ovarian tissue in sera of these patients, that originally suggested an autoimmune mechanism in the pathophysiology of premature ovarian failure. Additional evidence was brought forward with the histologic documentation of a lymphocytic infiltrate in the ovaries of patients with this disorder. It is the purpose of this article to summarize the existing data supporting the concept of autoimmunity as a cause of premature ovarian failure, to review a proposed mechanism of such an autoimmune response, and to discuss treatment of patients with this disorder.
Driver Responses to Augmented Reality Warnings and Alternatives at Urban Signalized Intersections

This study examined an augmented reality warning system that highlighted threats with a yellow arrow pointing towards the potential threat and a red bar below it. Sixteen drivers drove a fixed base driving simulator in a world with 61 intersections, 10 of which contained threats. Threats could appear from any direction, and go straight or turn. Each subject completed 3 test blocks of those intersections in a different random order – no warning, a warning tone, or a warning tone accompanied by the augmented reality warning. Warnings led to significantly fewer crashes (14 for augmented reality, 24 for warning tone, 30 for no warning). When compared to no warnings, augmented reality warnings also led to shorter response times (23%/35% less, depending upon how RT was measured), greater maximum brake pressures (42%) and greater maximum decelerations (18%). These results indicate that augmented reality warnings can be beneficial to drivers.
Dynamic behaviour of a high speed valve train system in a four-stroke engine

The Enduro and Cross Motorcycle's market is very competitive in concern to innovation technologies and products, since every year the most important manufacturers launch new improvements to its models, increasing power, handling and performance. For the last years, AJP Motos, Lda. , have been tried to play a role in this market with singular solutions in their products. They are building an image about producing high performance enduro and cross motorcycles for everyday usage. To understand the philosophy of AJP, we can take a look at the model PR5. We can easily distinguish this motorcycle from other competitors by its frame, made from aluminium, with an exclusive design. It was made with the goal of lowering the centre of gravity, by placing the fuel tank under the driver's seat. Despite representing a market niche, AJP products are now riding in 4 continents, receiving positive reviews from pilots and magazines. In order to increase the satisfaction from clients, AJP's collaborators keep pushing the models to a higher level of performance, what requires more powerful engines. For this company, it is not easy to produce their own engine or even go to the market and search for a high performance engine, so that its still possible to keep their model's competitive price. Nevertheless, AJP knew that the performance of an engine is highly in uenced by the quality of the combustion inside the cylinder, which in its turn depend on the admission of the air and fuel, as the exhaust of the combustion gases, as well as its timing. Therefore, the idea was to increase the power of the engine by improving its Valve Train System. For many decades, motorcycle producers have been trying to increase the performance of valve train systems in 4-stroke engines, because its response a ects the performance of the motorcycle. Some companies have invented their own solutions (for example: Ducati with the Desmodromic or Honda with the Unicam), while others use the standard ones (Single or Double Over Head Camshaft). The AJP Motos, Lda. solution, Innercam, is not yet ready for market because of its short life working time. As so, the goal of this thesis is to create a model that is able to describe the Dynamic behaviour of the mechanism in order to predict vibration responses of speci c degrees of freedom. The results obtained in previous works were given, some weaknesses and strengths analysed in order to produce knowledge and development in this Engineering subject.
The prevalence of head louse infestation among urban and rural children in Korea

: The prevalence of head louse (Pediculus hamanus var. capitis) infestation in preschool and school children in 9 urban and 8 rural areas of Korea, was investigated. Of 11,865 children who were examined for head lice and nits, 2,900(24.4%) were found infested. The over-all infestation rate of rural children, 58.9%, was higher than that of urban children, 14.4%. There also existed significant differences in the infestation rate among various regions of urban as well as rural areas. Females were more infested than males. But there was no differences in infestation rate in either sex of preschool age. The infestation rate increased gradually from the age of 6, reached a plateau between 9-12 years of age and thereafter slowly decreased. The infestation rate of an orphanage children was higher than that of general childhood population. Health education and mass-delousing attempt are urgently required to lower such a high prevalence of head louse infestation in Korea.
The Taxonomy Of

— The adult male and female of Leptostylis vemae Bacescu-Me§ter, 1967 are described and illustrated. This species is transferred to the genus Ekleptostylis Stebbing, 1912 and the description of Ekleptostylis heardi McLelland & Meyer, 1998 is emended. Both species were found in the Magellan Strait, Beagle Channel, Drake Passage and off Argentina. In addition, E. vemae was found off Uruguay. Diastylis pseudinomata Ledoyer, 1977 from the Ker-guelen Islands also is transferred to the genus Ekleptostylis, resulting in a total of four species now in this genus.
ANTIBODY PRODUCTION IN VITRO

The effect of high specific activity thymidme-3H on proliferation and antibody production, using the hemolytic plaque-forming technique, by spleen cell suspensions in vitro from rabbits killed after a boost of SRC's has been studied. High specific activity thymidine-3H inhibited the proliferative ay well as the antibody response to antigen, and it was conduded that this was the result of the incorporation of radioactive 3H into the nuclei of dividing cells which were synthesizing antibody in these cultures. The stimulation of the rate of DNA synthesis by specific antigen could be correlated with the ability of antigen to maintain antibody production, as measured by the specific hemolytic plaque-forming technique, above levels found in control cultures, incubated without antigen. Radioautographic studies of PFC's in vitro showed that the majority of the cells arose from the DNA-synthesizing population of cells in these cultures, confirming the conclusions from the results of the inhibitory effects of high specific-activity thymidine-3H on PFC's. It was found that these PFC's, labeling with thymidine-14C, formed only a small proportion of all the cells labeled in this way in these cultures. The postulation was made that antigen, in vitro, provided a stimulation for cell proliferation in the responsive population of rabbit spleen cells, but that only a small proportion of this population could be induced by antigen to synthesize antibody.
Extinction Probabilities for British Island Birds: A Reply

Diamond and Pimm (1993; hereafter referred to as DP) hypothesize that errors in our estimation of distances between islands and mainland, and our categorization of islands as either channel or oceanic islands, vitiate our earlier analyses (Tracy and George 1992; hereafter eferred to as TG). As noted by DP, the determination fthe distances between islands and mainlands is difficult because, among other things, "mainland" needs to be defined. Thus, TG abandoned actual distances and instead categorized islands as being either near (<6 km) or far (>6 km) from the mainland. Nevertheless, DP have suggested that our estimates (in TG) of distances between islands and mainland (Johnson and Simberloff 1974) were in error based on estimates given by Reed (1981). We rechecked these distances using several maps (Woodland 1979; The Ordnance Survey Road Atlas of Ireland 1985; Routemaster Series of Great Britain: Northern Scotland 1987; The Times Atlas of the World 1988) and found (a) errors in estimates given by Reed and (b) two ambiguous cases, both pointed out by DP. The first case was that we categorized Hascosay as far from the British Isles when actually it is near to the smaller Shetland Islands, which may be the immediate source of birds colonizing Hascosay. The second is that we categorized Cape Clear as near because we mistakenly identified nearby Sherkin Island as part of the mainland. We have rerun our previous analyses in TG by recategorizing Hascosay as a near island and Cape Clear as a far island, and the results are not statistically different from those in TG (i.e., the variable "distance to mainland" was once again not significant, and the difference in explained variance between TG and the new analysis was only a fraction of 1%). Our categorization of islands as channel or oceanic was, indeed, arbitrary. Such categorizations are by their very nature arbitrary, and we should have presented the bases for our categorizations in TG. We categorized islands as being oceanic if they were found either in the Atlantic Ocean or the North Sea. We categorized islands as channel if they were in the St. Georges Channel, the North Channel, the English Channel, the Bristol Channel, the mouth of the river Dee, or the Irish Sea. The importance of island type, vis-a-vis oceanic or channel (as we defined them), was shown to be statistically significant inTG, and the statistical models including island type (along with several other variables pertaining to characteristics of the bird species and the islands; see TG) nearly doubled the explained variance in the data (from 24.6% to 45.4%) in comparison to models containing only the independent variables used in Pimm et al. (1988).
Lossy Compression of Remote Sensing Images with Controllable Distortions

In this chapter, approaches to provide a desired quality of remote sensing images compressed in a lossy manner are considered. It is shown that, under certain conditions, this can be done automatically and quickly using prediction of coder performance parameters. The main parameters (metrics) are mean square error (MSE) or peak signal-to-noise ratio (PSNR) of introduced losses (distortions) although prediction of other important metrics is also possible. Having such a prediction, it becomes possible to set a quantization step of a coder in a proper manner to provide distortions of a desired level or less without compression/decompression iterations for single-channel image. It is shown that this approach can be also exploited in three-dimensional (3D) compression of multichannel images to produce a larger compression ratio (CR) for the same or less introduced distortions as for component-wise compression of multichannel data. The proposed methods are verified for test and real life images.
Dark Cutting Incidence in Holstein Friesian, Brown Swiss and Eastern Anatolian Red Cattle Slaughtered Under Turkish Commercial Slaughter Conditions

The aim of this study was to compare the incidence of dark cutting (DC) in Holstein Friesian (HF, n=382), Brown Swiss (BS, n=294) and Eastern Anatolian Red (EAR, n=212) male cattle slaughtered under Turkish commercial slaughter conditions. The importance of some factors (transport distance from farm to abattoir, lairage time, waiting type at abattoir, carcass weight and behaviour prior to slaughter) influencing of normal, moderate DFD and DFD carcass frequency on breed were also evaluated. There was influence of breed on the incidence of dark cutting condition. In HF, BS and EAR, males produced 54, 47 and 68% moderate DFD carcasses; 23, 34 and 25% DFD carcasses, respectively. Normal carcass percentage was lower in EAR (8%) compared to in HF (24%) and BS (19%). The results show that there were apparent differences in behaviour of these breeds prior to slaughter. During slaughter BS and EAR males had more excitable temperament than HF males. The present study also indicated that the incidence of dark cutting was higher for long haul transport and short lairage time. But, we concluded that the main cause of dark cutting of breed was the free waiting of animals at abattoir pens until slaughter under Turkish commercial slaughter conditions.
Antibiogram and multidrug resistance patterns of Staphylococcus aureus (MDRSA) associated with post operative wound infections in Basrah - Iraq

SUMMARY: Fifty-two clinical samples collected from patients with postoperative wound infections in various age groups were examined for presence of multidrug-resistant bacterial pathogens – in especially – Staphylococcus aureus. The majority of samples were for age between 31 and 40 yrs (32.69%) followed by other age groups, while the lowest samples were taken from age group 1 to 10 yrs (5.76%) P<0.05. A total of 131 isolates were identified and the main causative agent was S. aureus (24 isolates 18.32%), while other bacterial types isolated from postoperative wounds were as follow: Escherichia coli 16 (12.21%), Klebsiella spp 11(8.39%), Enterobacter cloaeca 8 (6.1%), Proteus spp 7(5.34%), Pseudomonas aeruginosa 20 (15.26%), Staphylococcusepidermidis 11 (8.39%), Staphylococcus saprophyticus 8 (6.1%), Staphylococcus xylosus 5 (3.81%), Viridance streptococci 10 (7.63%), Streptococcus pyogenes 7 (5.34%), and Enterococcus faecalis 4 (3.05%) P<0.01. Sixteen antibiotics were used to test the resistance of S. aureus. Penicillin G gave 100% resistance ratio for all of 24 tested isolates, while the highly affected antibiotic was cefotaxime that gave the lowest resistance percentage (16.66%). Other antibiotics had ranges of resistance between these limits P<0.01. S. aureus developed a resistance mode for at least eight antibiotics. The biggest percentage of resistance was for the resistance of four antibiotics (21.18%) P<0.01.
Effect of Dietary Energy Supplementation on Feed Intake, Growth and Reproductive Performance of Goats under Grazing Condition

Six female sheep were used in a 90 day trial to study the effect of dietary energy supplementation to grazing on feed intake, growth and reproductive performance of female sheep. Animals were blocked according to live weight and blocked groups were assigned at random into two feeding regimes i.e. low and high energy (10.02 and 11.98 MJ ME/kg DM). Each sheep received 250 grams of supplemental diet in addition to grazing. Results showed that, feeding of sheep with increased levels of dietary energy supplementation did not have significant (P>0.05) differences for daily average dry matter and crude protein intake. However, daily average ME intake significantly (P 0.05) for all dietary energy regimes. Average daily live weight gain significantly (p<0.05) increased from 34.8 to 48.5 g/d as the level of supplement energy increased from 10.02 to 11.98 MJ ME/Kg DM. The birth weight of lambs was highest i.e. 0.71 kg fed high energy diet and lowest i.e. 0.50 kg fed low energy diet. These results indicate that, increasing levels of supplemental energy improve growth and reproductive performance of female sheep. Therefore, supplementation of higher level of dietary energy (11.98 MJ ME/kg DM) may be suggested for optimizing growth and reproductive performance of female sheep under grazing condition.
Adaptive Resource Allocation for Computation Offloading

Although mobile devices today have powerful hardware and networking capabilities, they fall short when it comes to executing compute-intensive applications. Computation offloading (i.e., delegating resource-consuming tasks to servers located at the edge of the network) contributes toward moving to a mobile cloud computing paradigm. In this work, a two-level resource allocation and admission control mechanism for a cluster of edge servers offers an alternative choice to mobile users for executing their tasks. At the lower level, the behavior of edge servers is modeled by a set of linear systems, and linear controllers are designed to meet the system’s constraints and quality of service metrics, whereas at the upper level, an optimizer tackles the problems of load balancing and application placement toward the maximization of the number the offloaded requests. The evaluation illustrates the effectiveness of the proposed offloading mechanism regarding the performance indicators, such as application average response time, and the optimal utilization of the computational resources of edge servers.
Importance of the Nanofluid Preparation for Ultra-Low Interfacial Tension in Enhanced Oil Recovery Based on Surfactant–Nanoparticle–Brine System Interaction

The main objective of this study is to evaluate the effect of the preparation of the nanofluids based on the interactions between the surfactants, nanoparticles, and brine for being applied in ultra-low interfacial tension (IFT) for an enhanced oil recovery process. Three methodologies for the addition of the salt–surfactant–nanoparticle components for the formulation of an efficient injection fluid were evaluated: order of addition (i) salts, nanoparticles, and surfactants, (ii) salts, surfactants, and then nanoparticles, (iii) surfactants, nanoparticles, and then salts. Also, the effects of the total dissolved solids and the surfactant concentration were evaluated in the interfacial tension for selecting the better formulation of the surfactant solution. Three nanoparticles of different chemical natures were studied: silica gel (SiO2), alumina (γ-Al2O3), and magnetic iron core–carbon shell nanoparticles. The nanoparticles were characterized using dynamic light scattering, zeta-potential, N2 physisorption at −196 °C, and Fourier transform infrared spectroscopy. In addition, the interactions between the surfactant, different types of nanoparticles, and brine were investigated through adsorption isotherms for the three methodologies. The nanofluids based on the different nanoparticles were evaluated through IFT measurements using the spinning drop method. The adsorbed amount of surfactant mixture on nanoparticles decreased in the order of alumina > silica gel > magnetic iron core–carbon shell nanoparticles. The minimum IFT achieved was 1 × 10–4 mN m–1 following the methodology II at a core–shell nanoparticle dosage of 100 mg L–1.
