The Impact of Fasciolosis on Food Security in Nigeria: A Review

A review was conducted to highlight the direct and indirect impact of bovine fasciolosis on food security in Nigeria. The direct impact on livestock productivity include; host mortality and partial or total condemnation of organs. Indirect losses in sheep include; reduced production and quality of wool reduced lambing percentages, poor growth rate of lambs and increased costs for replacement stock. In cattle, losses include; reduced production and quality of milk in dairy cattle, lower growth rates and lower feed conversion rates in fattening cattle and expenditures for anthelmintics. The economic contribution of animal production in ensuring food security in Nigeria cannot be overemphasized. Livestock production constitutes an important component of Nigeria agricultural development; animal protein, raw materials for agro allied based industries. It was therefore concluded that the potential for increasing livestock production can only be fully realized if the animals are adequately protected against adverse effects of diseases. Profitability of animal product demand efficient husbandry of animals, as diseases remain a profit limitation factor in many tropical countries. For sufficient livestock production to be fully realized to meet the ever growing population Nigeria, integrated approach to fasciolosis control is required to increase the present level of livestock production.
NUMA Distance for Heterogeneous Memory

Experience with Intel Xeon Phi suggests that NUMA alone is inadequate for assignment of pages to devices in heterogeneous memory systems. We argue that this is because NUMA is based on a single distance metric between all domains (i.e., number of devices "in between" the domains), while relationships between heterogeneous domains can and should be characterized by multiple metrics (e.g., latency, bandwidth, capacity). We therefore propose elaborating the concept of NUMA distance to give better and more intuitive control of placement of pages, while retaining most of the simplicity of the NUMA abstraction. This can be based on minor modification of the Linux kernel, with the possibility for further development by hardware vendors.
CRUM W HEN T URNING INTO M AINTENANCE : A S INGLE C ASE S TUDY

Global software development using agile methods is commonplace in software industry nowadays. Scrum, as the agile development management framework, can be distributed in many ways, especially concerning how the key roles are presented in different sites. We describe here a single case study of a distributed Scrum, mainly for maintenance of the already constructed web portal. Using a qualitative method, both working well and challenging parts of the software work, as experienced by the project stakeholders, are revealed and discussed.
A 10-MHz Isolated Synchronous Class-Φ2 Resonant Converter

Because of the forward recovery, the performance of the diodes degrades seriously at multimegahertz, causing extremely high power loss. So, the synchronous rectification (SR) is strongly desired in the multimegahertz resonant converters. This paper proposes a self-driven level-shifted resonant gate driver (RGD) for the SR FET in a 10-MHz isolated class-Φ2 resonant converter. The proposed RGD provides precise switching timing for the SR so that the body diode conduction loss can be minimized. A control stage is introduced to the proposed RGD to block the circulating current and the low-impedance path in the driver to realize ON-OFF control of the converter with high efficiency. The proposed RGD also generates a tunable dc bias to increase the peak gate voltage and extend the conduction time with the optimal RDS(on) so that the average RDS(on) and the associated conduction loss can be reduced significantly. A 10-MHz prototype with 18-V input and 5-V/2-A output was built. At full load of 2 A, the proposed RGD improves the efficiency from 80.2% using the conventional RGD to 82% (an improvement of 1.8%). Compared to the efficiency of 77.3% using the diode rectification, the efficiency improvement is 4.7% at full load.
Réutiliser des textes dans un contexte éducatif

Les collections de ressources numeriques peuvent etre exploitees dans un cadre educatif, par exemple comme stimuli dans des questions de test ou comme des illustrations dans des objets pedagogiques. De nombreux detenteurs de collections de ressources media affichent de plus en plus l’ambition que leurs ressources soient utilisees dans un contexte educatif. Neanmoins, les metadonnees associees a ces ressources ne sont souvent pas directement utilisables comme criteres de selection. Des extraits de romans ou des articles de l’actualite economique, s’ils ne sont pas des ressources pedagogiques en eux-memes presentent des caracteristiques qui les rendent plus ou moins interessants et accessibles pour un profil d’apprenant et dans un contexte pedagogique particulier. Nous presentons dans cet article les mesures de difficulte des textes qui peuvent permettre d’annoter une collection et de qualifier le contexte pedagogique dans lequel elle pourra etre valorisee. Nous avons mis en œuvre des mesures statistiques, syntaxiques et semantiques dans un systeme unique afin d’operer des combinaisons en fonction de l’importance relative que chaque mesure doit avoir dans un contexte et pour un type de texte particuliers. Nous avons utilise une approche classique basee sur des calculs statistiques, ainsi qu’une approche de web mining et des technologies semantiques. Nous avons teste le systeme avec des jeux de donnees precalibres. Nous montrons les possibilites offertes par un outil ouvert pour l’evaluation de la reutilisabilite des collections de ressources multimedias dans un environnement educatif.
Environmental determination of the male morph in the ant Cardiocondyla obscurior (Hymenoptera: Formicidae)

Cardiocondyla is one of the few ant genera in which winged dispersing males coexist with wingless fighter males, which predominantly mate inside their maternal nests. Male polymorphism is not genetically determined but induced by environmental conditions (e.g., a decrease in temperature). The factors leading to the production of winged males were studied in more detail by exposing colonies of C. obscurior to a specific set of rearing conditions. A "stressful" environmental condition (rearing temperature lowered on average by 5°C) experienced for at least two days, the decrease of temperature by a minimum of 3°C, and the addition of protein-rich food triggered the development of winged males. In contrast, a smaller decrease in temperature, starvation, encounters with workers from other species, and encounters with alien, conspecific winged males did not induce the production of winged males. Colonies differed strongly in their reaction to changing environmental conditions, which might indicate a difference in their threshold sensitivity. The results are discussed and compared with data from other dimorphic insect species.
Recovery, Persistence, and Sequelae in Hepatitis C Virus Infection: A Perspective on Long-Term Outcome

Hepatitis C has emerged in recent years as the most common basis for liver disease in the United States, having infected an estimated 3.9 million people in this country and an estimated 170 million worldwide. Currently, it is the predominant reason for undergoing liver transplantation. The disease it causes is characterized by silent onset in most infected individuals, a high rate of viral persistence, and the potential for development of ever-worsening chronic liver disease, ranging from chronic hepatitis to cirrhosis and occasionally to hepatocellular carcinoma. Such progression, when it occurs, is also most commonly a silent process that may take 20-40, and occasionally even more, years to reach its end point. Because of these characteristics, it has been exceedingly difficult to accurately assess the natural history. Efforts to accomplish this have consisted of retrospective, prospective, and cohort studies. The most concerning data have derived from the retrospective study approach, generally performed at tertiary referral centers. Because these centers commonly attract persons with existing chronic liver disease, they have tended to describe a high rate of progression to cirrhosis and cancer. This "referral bias" is avoided in the prospective and cohort study approach, and data derived from these studies indicate a lower rate of progression and a correspondingly higher rate of either recovery or minimal liver disease. In this review, we briefly describe potential mechanisms of viral persistence; present detailed information on outcomes that have derived from retrospective, prospective, and cohort studies, involving both adults and children; examine the data regarding progression of fibrosis and of progression to hepatocellular carcinoma; consider cofactors that might enhance liver disease progression; and report the emerging data that suggest that spontaneous viral clearance may be higher than is currently believed. We conclude with the view that severe, life-threatening, progressive liver disease clearly occurs in a sizable minority (perhaps 30%) of chronically infected persons but speculate that fibrosis progression is neither linear or inevitable and hence that most hepatitis C virus carriers will have either a stable nonprogressive course or such indolent progression that they will die from an unrelated disease before the severe sequelae of hepatitis C become manifest or will have a sustained "curative" response to therapy. Although this view provides reasonable hope to the hepatitis C virus-infected individual, it does not deny the enormous burden this infection presents as the result of its high prevalence and global distribution. The sheer magnitude of the infected population will result in a large number with severe life-threatening liver disease even if the proportion of infected individuals that develop progressive disease is relatively small.
Extravasation of liposomal daunorubicin in patients with AIDS-associated Kaposi's sarcoma: a report of four cases.

PURPOSE/OBJECTIVES To report on four patients with AIDS-related Kaposi's sarcoma who were treated with liposomal daunorubicin (DaunoXome, NeXstar Pharmaceuticals, Inc., San Dimas, CA) as part of phase I/II and phase III clinical trials and who experienced extravasation during IV infusion. DATA SYNTHESIS All patients were treated with ice as an immediate intervention. In addition, two patients received treatment with multiple subcutaneous injections of steroids. Two patients experienced erythema, swelling, and pain after the extravasation. Two patients who were treated aggressively reported erythema and swelling without pain. Three patients observed changes in the texture of their skin that was accompanied by decreased sensation, which developed after 8-16 weeks. These changes completely resolved in all patients receiving intervention after six months. None of the patients suffered tissue necrosis. CONCLUSIONS Extravasation with liposomal daunorubicin is notable for the absence of tissue necrosis that typically is observed with anthracyclines. Long-term effects were limited to skin discoloration and decreased sensation, both of which resolved in all patients. IMPLICATIONS FOR NURSING PRACTICE The lack of observed skin necrosis with daunorubicin suggests a treatment advantage with a reduction in the required aggressive extravasation procedures for free anthracyclines as well as increased safety for the patient. Additional data is needed to confirm these observations.
Corporate Concentration and Technological Change in the Global Seed Industry

In the past three decades, the seed sector has experienced, and is now again experiencing, corporate concentration trends. The fallout of this consolidation is the subject of numerous concerns. However, the seed sector is rather poorly understood. Thus, it is useful to understand it better and to investigate the potential impact on the agri-food chain of the trend toward increased corporate concentration. The first part of this paper presents the main characteristics of the global seed sector, its stakeholders, and its size in the agri-food chain. Next, the corporate consolidation trends of the seed industry over the past two years are examined. The technological evolution of the seed sector is also briefly presented. In the last part of this paper, the fallout of recent mergers and acquisitions in the seed industry are analyzed. Opposing views are expressed on the impact of these mergers and acquisitions in the agri-food chain: while certain stakeholders worry about the risk of food power by the biggest companies, some others expect useful innovations.
Schulenorientierte versus Störungsorientierte Psychotherapien in der Psychiatrie

Zusammenfassung Die frühe Phase der Psychotherapieentwicklungen war ganz geprägt von den großen Schulen der Psychoanalyse, Tiefenpsychologie und Verhaltenstherapie. Dementsprechend waren auch die Zulassungsprinzipien der so genannten Richtlinienpsychotherapie ganz auf die Psychotherapieschulen zugeschnitten. In den letzten Dekaden hat sich in der psychotherapeutischen Forschung und Praxis dagegen in weiten Bereichen eine störungsfokussierte Psychotherapie mehr und mehr durchgesetzt, welche, fokussiert auf die psychopathologischen aber auch pathogenetischen Besonderheiten verschiedener konkreter Störungsbilder, psychotherapeutische Elemente aus den unterschiedlichen Schultraditionen symptomzentriert integriert. In diesem Artikel wird diese Entwicklung exemplarisch nachgezeichnet und auf die Notwendigkeit hingewiesen, dass diese Entwicklungen in der psychotherapeutischen Praxis auch ihre Entsprechung im gesundheitspolitischen Zulassungsreglementarium finden sollte.
Hyperphosphorylation and aggregation of tau in mice expressing normal human tau isoforms

Neurofibrillary tangles are composed of insoluble aggregates of the microtubule‐associated protein tau. In Alzheimer's disease the accumulation of neurofibrillary tangles occurs in the absence of tau mutations. Here we present mice that develop pathology from non‐mutant human tau, in the absence of other exogenous factors, including β‐amyloid. The pathology in these mice is Alzheimer‐like, with hyperphosphorylated tau accumulating as aggregated paired helical filaments. This pathologic tau accumulates in the cell bodies and dendrites of neurons in a spatiotemporally relevant distribution.
Predicted intake of trace elements and minerals via household drinking water by 6-year-old children from Krakow, Poland. Part 5: Zinc

Zinc (Zn) exposure in pre-school children via household drinking water collected by a double sampling method (morning, evening) was evaluated in a sample of the Polish population. Zn concentration was measured by flame atomic absorption spectrometry. Rural and suburban Krakow sites were non-distinguishable in respect of Zn concentrations. However, significantly lower Zn was found in urban as compared with non-urban sites [geometric mean (95% confidence interval) 0.14 (0.01–1.95) mg l−1 versus 0.52 (0.03–10.2) mg l−1, p < 0.001. ] Zn levels in water standing overnight in pipelines were higher in all sites by 0.36 mg l−1 on average, but observed really contaminations were higher. The Zn limit based on the taste and colour of drinking water (3 mg l−1) was exceeded in 1% and 10% of households from urban and non-urban sites, respectively. The Zn intake predictions for evening water samples for 6-year-old children averaged between 2% and 9% of the recommended dietary allowance (RDA, 10 mg day−1) for urban and non-urban sites, respectively. Mean Zn intake prediction for the exceedance fraction was 64% of RDA. In conclusion, overnight contamination of drinking water from in-house pipelines was significant and common to all sites investigated. Secondly, drinking water can be considered a significant contributor to dietary Zn intake by children in non-urban sites and may shift the population borderline of deficiency.
Cooperative two-path relay channels: Performance analysis using a Markov framework

We consider a cooperative two-path relay channel (TPRC) where a data source transmits new packets to a corresponding destination, with the assistance of two intermediate relays alternatively. When the transmitted source packet is successfully decoded by a relay, the relay proceeds to forward this packet in the subsequent time slot, otherwise it simply stays silent. Due to the inter-relay channels, the decoding result at a relay in the current time slot depends on the decoding result at the other relay in the previous time slot and not on that preceded it. In view of this property, we employ a Markov framework to analyze the decoding performance at the relays. The decoding of successive packets received at the destination can be similarly analyzed by using a Markov chain. Closed-form expressions of the outage probability are derived for TPRC by exploiting the properties of a Markov chain. Numerical results demonstrate that with the proposed scheme, a reasonably good performance is achieved with only a single-slot delay and relatively low complexity.
A Novel Technique for Optimal Feature Selection in Attribute Profiles Based on Genetic Algorithms

Morphological and attribute profiles have been proven to be effective tools to fuse spectral and spatial information for classification of remote sensing data. A wide range of filters (i.e., number of levels in the profiles) is usually necessary in order to properly model the spatial information in a remote sensing scene. A dense sampling of the values of the parameters of the filters generates profiles that have both a very large dimensionality (leading to the Hughes phenomenon in classification) and a high redundancy. In this paper, a novel iterative technique based on genetic algorithms (GAs) is proposed to automatically optimize the selection of the optimal features from the profiles. The selection of the filtered images that compose the profile is performed by dividing them into three classes corresponding to high, medium, and low importance. We propose to measure the importance (modeled in terms of discriminative power in the classification task) using a random forest classifier, which provides a rank for each feature with its model. Only the set of images associated with the highest importance is selected, i.e., preserved for classification. The proposed technique is applied to the features labeled with medium importance, whereas the images with the lowest importance are removed from the profile. This method is employed to classify three hyperspectral data sets achieving significantly high classification accuracy values. A parallel computing implementation has been developed in order to significantly reduce the time required for the run of the GAs.
War and Television

Since the 1960s, and culminating in the Gulf conflict of last year, television has come to play an ever more decisive role in the preparation and planning, as well as in the execution, of war. It is said that the Vietnam war was lost in American living rooms; and more recently, that the Gulf war was won there. In this highly readable new book, Bruce Cumings studies the history of television's coverage of US warmaking since World War II. Cumings' own experience in the production of a Thames Television film "Korea: The Unknown War" and his difficulties getting the programme aired on American public television, tell a story of struggle with an array of media executives, retired soldiers, bureaucrats from both Koreas, and assorted public figures. Cumings shows how his film was shaped by media people on both sides of the Atlantic to conform to prevailing views of a war that neither the United States nor Britain wishes to remember accurately.

Power Allocation and Subcarrier Pairing Algorithm for Regenerative OFDM Relay System

Relayed transmission is a promising technique that helps in attaining broader coverage and in combating the impairment of the wireless channel. Orthogonal frequency division multiplexing (OFDM) technique is promising for the next generation wireless communication system. Therefore, the combination of two techniques named OFDM-relay will be a good candidate technology for future wideband wireless communication. This paper investigates the resource allocation of two-hop regenerative OFDM relay system with/without diversity. Optimization of power allocation (PA) is proposed to maximize the channel capacity and subcarrier pairing strategy is adopted to improve the system performance further. In addition, the resource allocation for multi-hop OFDM system without diversity is also presented. The resource allocation is based on the instantaneous channel state information (ICSI) and aims to maximize the system capacity. The order pairing strategy is proved to be a good choice for multi-hop regenerative OFDM relay system without diversity. The simulation results show that combining with the pairing algorithm, efficient power allocation will greatly improve the system capacity.
Facial Expression Recognition Using Feedforward Neural Networks

Our goal was to create a facial expression recognition neural network. This network would take pictures of human faces as input and to identify a specific person, a facial expression, and detect whether or not the subject's eyes were open or closed. For the purpose we used the multi-layer perceptron neural network (MLP) with backpropagation (BP) as a reference platform to determine this architecture's suitability for facial recognition. We compared the efficiency of MLP with sigmoidal activation function in the hidden layer, and a combination of sigmoidal and Gaussian activation functions. The concept of recognizing the facial expression and the state of the eyes is very different from the general face recognition, which has been investigated over the years. We are not only recognizing the individual, but also the subtle changes that take place when one changes their emotional state (although we have tested opposing emotions), or when one has closed their eyes. We have developed and tested four networks, and have also proven that a combination of sigmoidal and radial basis functions hidden neurons is better suited due to the nature of the activation functions in the feed-forward neural net.
