Trypanosoma vivax AND Borrelia burdgorferi IN CATTLE FROM THE NORTHEASTERN REGION OF THE STATE OF PARÁ , BRAZIL

GUEDES JUNIOR, D.S. ; ARAÚJO, F.R. ; SILVA, F.J.M. ; RANGEL, C.P.; BARBOSA NETO, J.D. ; FONSECA, A.H. Frequency of antibodies to Babesia bigemina, B. bovis, Anaplasma marginale, Trypanosoma vivax and Borrelia burgdorferi in cattle from the Northeastern region of the State of Pará, Brazil. [Freqüência de anticorpos para Babesia bigemina, B. bovis, Anaplasma marginale, Trypanosoma vivax e Borrelia burgdorferi em bovinos do nordeste do Estado do Pará, Brasil]. Revista Brasileira de Parasitologia Veterinária v. 17, n. 2, p. 105109, 2008. Departamento de Epidemiologia e Saúde Pública, Instituto de Veterinária, Universidade Federal Rural do Rio de Janeiro, BR 456, Km7, Seropédica, RJ 23890-000. E-mail: adivaldo@ufrrj.br Babesiosis, anaplasmosis, and trypanosomosis are relevant diseases, potentially causing morbidity in cattle, leading to economic losses. Borreliosis is import as a potential zoonosis. The objective of this study was to determine, by indirect enzyme-linked immunosorbent assay (ELISA), the frequency of seropositive cattle to Babesia bigemina, B. bovis, Anaplasma marginale, Trypanosoma vivax and Borrelia burgdorferi in cattle from the Northeastern region of Pará, Brazil. Sera samples from 246 female adult cattle from municipalities of Castanhal and São Miguel do Guamá were used. Crude antigens ELISAs were used to detect antibodies to all agents, except to A. marginale, to which an indirect ELISA with recombinant major surface 1a protein (MSP1a) antigen was used. Overall frequencies of seropositive animals were: B. bigemina 99.2%; B. bovis 98.8%; A. marginale 68.3%; T. vivax 93.1% and B. burgdorferi 54.9%. The frequencies of seropositive cattle to B. bovis and B. bigemina suggest a high rate of transmission of these organisms by tick in the studied region, which can be classified as enzootically stable to these hemoprotozoans. The low frequency of seropositive cattle to A. marginale may be attributed to a lower sensitivity of the recombinant antigen ELISA utilized or a distinct rate of inoculation of this rickettsia by ticks, as compared with Babesia sp. transmission. The high frequency of seropositive cattle to T. vivax indicates that this hemoprotozoan is prevalent in herds from the Northeastern region of Pará. The rate of animal that showed homologues antibodies to B. burgdorferi indicates the presence of the tickborne spirochaetal agent in the cattle population in the studied region.
Complementary value of five carcinoma markers for the diagnosis of malignant mesothelioma, adenocarcinoma metastasis, and reactive mesothelium in serous effusions

Cytological slides of serous fluids of 41 malignant mesotheliomas, 88 metastatic adenocarcinomas, and 25 reactive effusions were immunostained with the antibodies anti‐CEA, MOC‐31, Leu‐M1, Ber‐EP4, and B72.3. Most mesotheliomas and all reactive fluids failed to stain with these antibodies. The sensitivity of the five markers to detect carcinoma cells differed remarkably. Especially MOC‐31, Ber‐EP4, and B72.3 stained with a high number of carcinoma cases and the complementary value of Ber‐EP4 and B72.3 to immunostain carcinoma cells was impressive: 94% of the metastatic adenocarcinoma cases reacted with Ber‐EP4 or B72.3 in contrast to 1 of 41 malignant mesotheliomas.

The Complexity of Statistical Algorithms

We develop a framework for studying optimization problems over distributions. In the worst case these problems are typically NP-hard, even to approximate, and are usually addressed in practice by a range of heuristics. To understand the effectiveness of such approaches, we define a class of algorithms, called statistical algorithms, that captures many natural algorithms, e.g. local search, MCMC, and simulated annealing. We show that for specific optimization problems over distributions, namely, for variants of MAX-XOR-SAT, k-clique, and moment maximization, the complexity of any statistical algorithm grows exponentially in their input parameters. Our techniques are inspired by (and generalize) the statistical query model in learning theory, and in parallel to that concept, we can prove lower bounds on statistical algorithms for optimization problems over distributions using a single parameter that we call statistical dimension. Although this does not fully rule out efficient algorithms for such problems, it indicates the limitations of known heuristics.
Tubular aggregates: Sarcoplasmic reticulum origin, calcium storage ability, and functional implications

Muscle biopsy specimens from three patients with an autosomal dominant myopathy and tubular aggregates in both type 1 and type 2 fibers16 were investigated for immunofluorescent staining with antibodies to sarcoplasmic reticulum (SR) Ca‐pump protein and calsequestrin and for Ca2+ loading ability. The results show that type 1 and type 2 fibers are differentially reactive to anti–ca‐pump protein lgG and similarly reactive with affinity‐purified antibody to calsequestrin, which is in agreement with earlier observations in rat skeletal muscle.8 Tubular aggregates, which are shown to be highly reactive with either kind of antibody, appear to be sites of calcium accumulation for oxalatefacilitated adenosine triphosphate (ATP) dependent Ca uptake by chemically skinned fibers and thereby increase markedly the Ca loading capacity of the affected fibers.
Extending Options by Changing Their Underlying Assets

This article aims to examine a new type of exotic option, namely the generalized extendible option. Compared to traditional options, such an option has two characteristics: firstly, its maturity has the possibility to be extended for a given period; secondly, once the option is extended, its original underlying asset will be replaced by a new underlying asset. Within this framework, two option categories with different extension conditions are studied. For the first category, a plain-vanilla option will be extended automatically by the optionwriter without any additional premium payment from the optionholder if its payoff at the original maturity date is zero. For the second category, a plain-vanilla option can be extended by the optionholder by accepting to pay a predetermined additional premium at the original maturity date. For these European-style call and put options, closed-form formulas are derived to determine or to estimate their values. In addition, we have shown that generalized extendible options have numerous applications in different fields, such as corporate financing, corporate risk management, corporate capital structure analysis, funds structuring, and option modeling.
A bitter pill: formulary variability and the challenge to prescribing physicians.

BACKGROUND Multitiered, incentive-based formularies have been increasingly used as a mechanism to control prescription drug expenditures. Prescribing physicians who manage patients from multiple insurers must be familiar with the variability in their patients' formulary incentives to help patients choose therapy wisely. However, the degree of formulary variability among and within health plans over time is unclear. METHODS In 6 major health plans in California, we evaluated formulary incentive variability in 4 of the 5 drug classes with the highest expenditures in California: proton pump inhibitors, hydroxymethylglutaryl coenzyme A reductase inhibitors ("statins"), calcium channel blockers, and angiotensin-converting enzyme inhibitors. We categorized 20 branded members of these classes into either "preferred" or nonpreferred/uncovered categories. We calculated the consistency that brands were preferred across health plans and the frequency of changes in formulary status for each drug within plans between 2000 and 2002. RESULTS None of the branded drugs evaluated were preferred on all formularies in 2002, and 10% were not available on any of the formularies. Formulary status varied greatly across plans, and more than 60% of drugs were preferred on 2 to 4 of the 6 formularies studied. Formulary status within health plans varied between 2000 and 2002 in more than half of the plans in the drug classes evaluated. CONCLUSIONS In the drug classes evaluated, over a 2-year period, considerable variability was seen among and within formularies over time. This variability poses a challenge to physicians who wish to reduce patients' expenditures by prescribing the least expensive among similarly effective drugs within a drug class. This variability is especially relevant because recent legislation increases the likelihood that more Medicare beneficiaries will receive their medications from private health plans.
Phishing Websites Prediction Using Classification Techniques

Phishing is an important issue that faces the cyber security. This paper exploits the capabilities of classification techniques on Phishing Website Prediction (PWP), and introduces a methodology to protect users from the attackers. The blacklist procedure isn't a strong enough way to stay safe from the cybercriminals. Therefore, phishing website indicators have to be considered for this purpose, with the existence and usage of machine learning algorithms. Five different classification techniques have been used to evaluate their efficiency on (PWP) in terms of accuracy and the Relative Absolute Error (RAE) value for each one of them, with and without the feature selection process. WEKA tool was used for the implementation of these classifiers on a public dataset from NASA repository. The motivation behind this investigation is to employ a number of Data Mining (DM) algorithms for the prediction purpose of phishing websites and compare their effectiveness in terms of accuracy and RAE. Where DM classifiers have proved their goodness in this kind of problems.

Dissecting the voice: Health professions students' perceptions of instructor age and gender in an online environment and the impact on evaluations for faculty

Gender and age bias is well‐documented in academia with many studies demonstrating bias in students' evaluations of instructors. Failure of an instructor to meet gender or age‐based expectations can translate to lower scores or negative comments on evaluations. While there is some evidence of bias in students' evaluations of online instructors, current studies have not fully examined the relationship between bias and instructor vocal characteristics. First‐year dental students at two institutions were randomly assigned one of four videos on spinal cord anatomy to view. Videos contained identical content but were narrated by individuals of different gender and age (younger man, younger woman, older man, older woman). Students completed a content‐based prequiz, watched the video, completed a postquiz, and answered a questionnaire evaluating the video and instructor. Students at Institution A rated the younger man and younger woman highest for nearly every evaluation category. At Institution B students rated the older man and younger woman highest. Results reveal that the older woman's voice received the lowest rankings for nearly every question in both samples. This report confirms the presence of gender and age bias in student evaluations of instructors in an online environment and demonstrates that bias may surface in response to vocal characteristics. Bias may impact older women more significantly than other groups. Differences in results from Institution A and Institution B suggest that factors affecting student perceptions of instructors, and the roles that gender and age bias may play in student evaluations, are complex and may be contextual.

Food safety culture: the evolution of an emerging risk factor?

Purpose – Outbreaks of foodborne disease are often investigated to determine the causes although traditional approaches to identifying risk factors may not determine the real or underlying causes. The aim of this paper is to identify a food safety culture that can be used in addition to more traditional risk factors.Design/methodology/approach – A parallel is drawn between the use of the term “emerging pathogen” and the emergence of food safety culture as a risk factor in food poisoning outbreaks. The evolution of the term starting with organizational culture is developed via the literature on health and safety culture. The concept of food safety culture and reservations over the use of the term are examined along with possible distinctions between food safety culture and climate.Findings – The concept of food safety culture has direct parallels with “safety culture” and in the prevention of healthcare associated infections. The use of food safety culture is useful as part of outbreak investigation. It is.

Resonant based control algorithm for grid supportive solar PV power generating system

This study deals with the two stage solar photovoltaic (SPV) system employing resonant based control algorithm. This system not only feeds the power to the distribution network, moreover it also includes the features of load balancing, harmonics reduction and power factor correction. In first stage of the SPV system, a DC-DC boost converter is used. The duty ratio of the DC-DC boost converter is adjusted in such away so that system could track the maximum power. The maximum power is extracted from the SPV generator by utilizing an INC based MPPT (Maximum Power Point Tracking) control algorithm. In second stage, resonant control technique is utilized to estimate the fundamental active and reactive power components of the load currents. These are utilized to extract the peak value of reference grid currents. Simulation results are demonstrated to validate the control of SPV system.
Motor proficiency and physical fitness in adolescent males with and without autism spectrum disorders

This study compared components of motor proficiency and physical fitness in adolescents with and without autism spectrum disorders, and assessed the associations between the two measures within each group. A total of 62 adolescent males with (n = 31) and without (n = 31) autism spectrum disorders aged 10–17 years completed the Bruininks–Oseretsky Test of Motor Proficiency (2nd ed.), the BROCKPORT Physical Fitness Test, and the bioelectrical impedance analysis. The main findings are as follows: (1) adolescents with autism spectrum disorders had significantly lower scores on all motor proficiency and fitness measures, except body composition, than adolescents without autism spectrum disorders and that (2) the types of associations between the two measures differed significantly across the groups. Specific interventions to maximize motor proficiency and physical fitness in adolescents with autism spectrum disorders are urgently needed.
A Novel Packet Scheduling Algorithm for HSDPA Based on QoS Assurances

High speed downlink packet access (HSDPA) was introduced in WCDMA as an enhance technology. The objective of the major component fast packet scheduling is to ensure the fairness between users according to their instantaneous channel state. We proposed in this paper a novel packet scheduling algorithm for HSDPA which is based on QoS assurances. This algorithm is called classified wireless fair queuing which classifies flows into different class according to their average data rate. Each class is given different bandwidth guarantee and packets are scheduled in different slot, within each class it uses wireless fair queueing method to schedule each user. Simulation results and comparisons show that this algorithm could effectively reduce the average end-to-end packet delay especially for high data rate traffic and provide good fairness to each user.
Special Economic Zones: Issues in Corporate Governance

A SEZ(SEZ) is a geographical region that has economic laws that are more liberal than a country's typical economic laws. In India, eight previously existing Export Processing Zones have been converted into SEZs. The policy provides for setting up of SEZ's in the public, private, joint sector or by State Governments. It was also envisaged that some of the existing Export Processing Zones would be converted into Special Economic Zones. Over the past few years, the policy of promoting zones has found favour with the government of India. In 2005, it enacted the SEZ Act and the SEZ Rules were notified in February 2006. The policy is expected to give a big push to exports, employment and investment in SEZs. The SEZ Act gives a wide area of discretion to the State and Central Governments to regulate an SEZ as they see fit. What is crucially different about other south-Asian projects from the Indian model is that all these export promotion zones, special economic zones, free trade zones etc. were by and large state initiatives. The Indian SEZ program instead, shifts the burden of development and maintenance to the private investor. Again the legal regime inside a specific SEZ is the initiative of the concerned state government. In the context of a SEZ, the most pertinent facet of Corporate Social responsibility is the aspect of Corporate Social Rectitude, or corporate ethics. Writers have also tried to bring in a difference between social obligations and social responsibilities. They argue that social obligations imply corporate functioning within legal and social constraints, whereas social responsibility implies keeping in step with the prevailing social norms, values and expectations of performance. Concluding, a new initiative towards industrialization and manufacturing cannot violate basic fundamentals of corporate ethics and responsibility.
Inner Ear Anomalies in Cochlear Implantees: Importance of Radiologic Measurements in the Classification

Objective: To classify the inner ear anomalies of cochlear implantees with profound sensorineural hearing loss. Study Design: Retrospective case review. Setting: Tertiary referral center. Patients: For the normative data of the inner ear structures, the temporal bone computed tomography of 60 patients (120 ears) with normal bone-conduction threshold (<15 dB) were used, and the data were applied to 570 ears of 285 cochlear implantees. Interventions: Predesignated inner ear structures were measured in temporal bone computed tomography images from the normal and cochlear implantation groups using a computer-based caliper that formed part of a picture archiving and communication system. Main Outcome Measures: The inner ear anomalies were defined when the structures presented visually obvious malformations or the measurements deviated 2 standard deviations from the means in the normative data. Results: The application of normative data to 570 profound SNHL ears resulted in the identification of 293 individual anomalies in 127 anomalous ears. An enlarged vestibular aqueduct was the most common individual anomaly (49 cases), followed by vestibular enlargement (38 cases) and other semicircular canal dysplasia (37 cases). When the individual anomalies were reaccounted according to the more prominent anomaly where multiple anomalies were present in each ear, incomplete partition type II was the most common (34 ears), followed by cochlear hypoplasia (22 ears) and incomplete partition type I (20 ears). Conclusion: We suggested a measurement technique for the inner ear structures using computed tomography and derived normative measurements helpful for diagnosing inner ear anomalies. Using these normative data, we classified the inner ear anomalies of profound SNHL ears in cochlear implantees.
Multiservice Vertical Handoff Decision Algorithms

Future wireless networks must be able to coordinate services within a diverse-network environment. One of the challenging problems for coordination is vertical handoff, which is the decision for a mobile node to handoff between different types of networks. While traditional handoff is based on received signal strength comparisons, vertical handoff must evaluate additional factors, such as monetary cost, offered services, network conditions, and user preferences. In this paper, several optimizations are proposed for the execution of vertical handoff decision algorithms, with the goal of maximizing the quality of service experienced by each user. First, the concept of policy-based handoffs is discussed. Then, a multiservice vertical handoff decision algorithm (MUSE-VDA) and cost function are introduced to judge target networks based on a variety of user- and network-valued metrics. Finally, a performance analysis demonstrates that significant gains in the ability to satisfy user requests for multiple simultaneous services and a more efficient use of resources can be achieved from the MUSE-VDA optimizations.
