Arquivo Brasileiro de Medicina Veterinária e Zootecnia , 2003, DOI: 10.1590/S0102-09352003000500002
Abstract: this report describes the first preliminary characterization of porcine circovirus type 2 (pcv2) isolates from pigs affected with post-weaning multisystemic wasting syndrome (pmws) in brazil. diseased pigs were examined at necropsy and by histopathology. macroscopic and microscopic analyses revealed lesions reported to be typical of pmws, which included, respectively, emaciation, enlargement of lymph nodes, thymus atrophy and interstitial pneumonia, and granulomatous lymphadenitis with syncytial cells, among others. using nested polymerase chain reaction (pcr) or imunoperoxidase it was possible to detected dna or antigen of pcv2, respectively. the pcr' s amplified fragment could be differentiated from pcv1 and pcv2 from one another by restriction fragment length polymorphism (rflp) analysis. pcv2 dna was detected in 70% (14/20) of samples of pigs with clinical signs and lesions associated with pmws. this study shows that pcv2 is associated with lesions and symptoms indicative of pmws in pigs. it is also shown that the brazilian pcv2 isolates may have variation in their genome.

Abstract: This report describes the first preliminary characterization of porcine circovirus type 2 (PCV2) isolates from pigs affected with post-weaning multisystemic wasting syndrome (PMWS) in Brazil. Diseased pigs were examined at necropsy and by histopathology. Macroscopic and microscopic analyses revealed lesions reported to be typical of PMWS, which included, respectively, emaciation, enlargement of lymph nodes, thymus atrophy and interstitial pneumonia, and granulomatous lymphadenitis with syncytial cells, among others. Using nested polymerase chain reaction (PCR) or imunoperoxidase it was possible to detected DNA or antigen of PCV2, respectively. The PCR' s amplified fragment could be differentiated from PCV1 and PCV2 from one another by restriction fragment length polymorphism (RFLP) analysis. PCV2 DNA was detected in 70% (14/20) of samples of pigs with clinical signs and lesions associated with PMWS. This study shows that PCV2 is associated with lesions and symptoms indicative of PMWS in pigs. It is also shown that the Brazilian PCV2 isolates may have variation in their genome.

Abstract: the effect of the ultra-filtered spray-dried porcine plasma, associated to a commercial acid in the drinking water was tested for recovering pigs with clinical signs of the porcine postweaning multisystemic wasting syndrome (pmws). forty piglets with clinical signs of the pmws were used following a selection at 20 days after their housing in one finishing facility. they were divided in four treatment groups (t) of 10 pigs each: t1 - chlorine treated water ad libitum (control); t2 - solution prepared with 2.5% of plasma diluted in water; t3 - acid (selko? ) diluted in water at the concentration of 12 ml/10l; t4 - solution prepared with 2.5% of plasma diluted and the acid (selko? ) diluted in water at the concentration of 12 ml/10l. the pigs received no medication and were euthanized at 28 or 40 days after the beginning of the experiment for serological and pathological tests. differences at the weight gain and in the clinical-pathological situation were not observed among the treatments. however, pigs from t4 were in better clinical-pathological situation. the pigs of all four treatments showed a good recovery, although they were not medicated. even though, it was observed a high frequency of lesions compatible to pmws in the lungs, kidneys and lymph nodes. it was concluded that the plasma spray-dried associated to the acid did not improve the performance and the clinical-pathological situation of pigs with clinical signs of pmws.
SIMULATION AND ANALYSIS OF BB84 PROTOCOL BY MODEL CHECKING
J.R. SAHOO,S. SATAPATHY
International Journal of Engineering Science and Technology , 2011,
Abstract: Quantum Cryptography or Quantum key distribution (QKD) is a technique to securely distribute a bit string,among two parties by using laws of quantum mechanics. Its security relies on foundations of quantummechanics, where as classical cryptography relies on difficulty of certain mathematical problems that can not able to provide unconditional security. Progress of research in this field indicates that QKD will be available outside the laboratory within next few years. These devices have now become complex and more effort isneeded for their verification. In this paper, we will use the PRISM tool to analyze the security of BB84 protocol and more specifically the property of eavesdropping detection by combining the parameters of quantum channel and power of eavesdropper.
ARM7 Based Smart Car Security System.
J.R. Shaikh, S. M. Kate
International Journal of Engineering Trends and Technology , 2012,
Abstract: The main aim of this project is to offer an advance security system in CAR, which consists of a face detection subsystem, a GPS module, a GSM module and a control platform. The face detection subsystem can detect faces in cars during the period in which nobody should be in the car, and make an alarm loudly or soundlessly. The other modules transmit necessary information to users and help to keep eyes on cars all the time, even when the car is lost.In todays world, many new techniques such as biometric recognition technique, image processing technique, communication technique and so on, have been integrated into car security systems . At the same time, the amount of car lost is also increasing. Traditional car security systems depends on many sensors and cost is also high .When one car is lost, no more feedback could be available to help people to find it back.This system prototype is built on the base of one embedded platform ARM7 which controls all the processes. Experimental results illuminate the validity of this car security system.
Epidemiology, disease and control of infections in ruminants by herpesviruses - an overview : review article
J.R. Patel,S. Didlick
Journal of the South African Veterinary Association , 2012, DOI: 10.4102/jsava.v79i1.233
Abstract: There are at least 16 recognised herpesviruses that naturally infect cattle, sheep, goats and various species of deer and antelopes. Six of the viruses are recognised as distinct alphaherpesviruses and 9 as gammaherpesviruses. Buffalo herpesvirus (BflHV) and ovine herpesvirus-1 (OvHV-1) remain officially unclassified. The prevalence of ruminant herpesviruses varies from worldwide to geographically restricted in distribution. Viruses in both subfamilies Alphaherpesvirinae and Gammaherpesvirinae cause mild to moderate and severe disease in respective natural or secondary ruminant hosts. Accordingly, the economic and ecological impact of the viruses is also variable. The molecular characteristics of some members have been investigated in detail. This has led to the identification of virulence-associated genes and construction of deletion mutants and recombinant viruses. Some of the latter have been developed as commercial vaccines. This paper aims to give an overview of the epidemiology and pathogenesis of infection by these viruses, immuno-prophylaxis and mechanisms of recovery from infection. Since there are 128 ruminant species in the family Bovidae, it is likely that some herpesviruses remain undiscovered. We conclude that currently known ruminant alphaherpesviruses occur only in their natural hosts and do not cross stably into other ruminant species. By contrast, gammaherpesviruses have a much broader host range as evidenced by the fact that antibodies reactive to alcelaphine herpesvirus type 1 have been detected in 4 subfamilies in the family Bovidae, namely Alcelaphinae, Hippotraginae, Ovibovinae and Caprinae. New gammaherpesviruses within these subfamilies are likely to be discovered in the future.

Abstract: objectives: to describe and quantify clinical practice consultancy in a prison health care unit so as to evaluate likely differences from a community health care centre. to identify possible training needs when transferring health care staff from one system to another in the light of probable integration of prison health care into the public health system. methods: a transversal descriptive study was used for three primary health care teams: an urban health centre with a high work load, a rural health centre with a low work load, and the health care unit of a provincial prison (not a mega-prison). ransom sequential sampling was used to include all the medical activity generated in the consultancy. all activity programmed by the health professional and administrative consultancy was excluded, while efforts were made to locate troubled consultations. comparisons were made by contrasting differences in proportions. results: the prison health care unit showed higher statistically significant clinical activity in mental health, drug abuse, hiv and hcv infection management and specific primary health care problems (biopsychosocial integration is a therapeutic priority). in both community health centres there is more statistically significant activity in internal medicine and geriatrics. in the prison environment there is significantly higher troubled consultation. conclusions: in a future context of integration of prison health care services into the public health service, training in mental health care (especially addictive disorders) and in hiv-hcv infection management may be necessary for community health centre professionals wishing to transfer to prison health care units. the prison health care professional who wants to work in a public health centre may need training in internal medicine (especially geriatrics). the statistically significant results for health care in prison, primary health care and troubled consultation suggest that the gp plays a more active role
Actividad clínica en la consulta médica a demanda de un Centro Penitenciario frente a la de un Centro de Salud Comparisons between clinical practice consultation in a prison and in community health centres: differences and repercussions

Abstract: Objetivos: Describir y cuantificar la actividad clínica en las consultas de demanda de un Centro Penitenciario (CP) para valorar las posibles diferencias respecto a un Centro de Salud (CS). Identificar los posibles requerimientos de formación específica ante eventuales traslados de profesionales entre uno y otro medio, resultantes de una supuesta integración de la Sanidad Penitenciaria (SP) en el conjunto del Sistema Público de Salud (SPS). Método: Estudio descriptivo transversal. Se aplica en tres equipos de Atención Primaria (AP): un Centro de Salud Urbano de alta carga asistencial (CSU), un Centro de Salud Rural de baja carga asistencial (CSR) y un CP provincial -no tipo macro cárcel-. Muestreo aleatorio secuencial que incluye toda la actividad médica generada en la consulta de demanda. Se excluye toda la actividad programada por el profesional sanitario y las consultas administrativas. Se realiza un intento de reconocimiento de consultas conflictivas para el profesional. Las comparaciones se realizan mediante el test estadístico de Contraste de Diferencia de Proporciones. Resultados: En el CP se halla significación estadística (SE) de mayor actividad clínica en las áreas de salud mental, toxicomanías, manejo de infección VIH-VHC y de problemas específicos de AP (integración biopsicosocial prioritaria en su tratamiento). En ambos CS hay SE de mayor actividad en el conjunto del área de Medicina Interna (MI) y de Geriatría (G). En el medio penitenciario hay SE de mayor conflictividad en la consulta. Conclusiones: En un futuro contexto de integración de derecho de la SP, puede ser necesaria formación en salud mental, particularmente en trastornos adictivos, y en manejo de infección VIH-VHC para ejercer en un CP. Puede ser necesaria formación en el conjunto de Medicina Interna, particularmente en Geriatría, de médicos de CP para que se trasladen a CS. La significación obtenida, en la asistencia sanitaria de una prisión, de la AP y de la conflictividad, sugiere un papel más relevante del médico general en un CP que en el conjunto del SPS y puede ser un dato a tener en cuenta en la planificación de la anunciada integración de la SP en el SPS.

Hegde’s instability mechanics for the prediction of forming limit in sheet metal forming
G.S. Hegde,J.R. Nataraj,R. Sridhar
Archives of Computational Materials Science and Surface Engineering , 2009,
Abstract: Purpose: The purpose of the paper is to investigate the Hegde’s instability mechanics for the prediction of forming limit in sheet metal forming.Design/methodology/approach: Hegde’s Instability Mechanics (HIM) paves way for explaining the effects of diffuse instability and localization due to necking in sheet metal forming. For different ranges of stress ratios, the ratio of strain differentials has been computed and hence the forming limits are predicted.Findings: Basing the formulation of HIM on the von Misess yield criterion and applying the interface theory (briefed in appendix) the state-of- the-art purpose is deemed to be well served and demonstrated. Interface theory to explain in simple terms, gives the optimal decision variables in an ‘n’ dimensional hyper-space. The concept of HIM is demonstrated on isotropic and anisotropic materials. The anisotropic materials show better stability than isotropic materials in sheet metal forming. However the geometric instability is analyzed with the assumptions that the thickness stresses are negligible and biaxial state of stress persists in sheet metal forming.Practical implications: The observations are based on the theoretical findings for which the experimental validation exists in the reviewed references.Originality/value: To the sincere knowledge of authors, is both different and unique of its kind in sheet forming mechanics needing horizontal exploration by potential researchers.

Abstract: objective: to retrospectively review the response of patients with peyronie?s disease (pd) treated with colchicine as monotherapy and colchicine plus vitamin e. material and methods: we evaluated 100 men with pd. a dose of 1.5mg/day oral colchicine as monotherapy (ccm) was given to 59 patients and 1.5/800mg/day oral colchicine/vitamin e (ccve) to 41. response was categorized as follows: good response, when at least 2 of the following conditions were achieved: decrease/stabilization of curvature and/or plaque and/or pain relief. partial response if one of the former conditions were observed. no response and worsening. no statistical differences between groups were found. results: good response was observed in 39% vs 41% in the ccm and ccve groups respectively. when looking at each variable, we observed improvement on the plaque?s size in 36 vs 29%, pain relief in 46 vs 57% and curvature 32 vs 33% in the ccm and ccve respectively. none of these differences were statistically significant. conclusion: oral conservative treatment with ccve failed to show statistically significant differences in efficacy in pain relief, penile curvature or plaque size against ccm in this study. however, there is slight evidence of a positive prognostic effect on the conservative treatment when history of previous unsuccessful pd treatment was recorded, this was statistically significant in the ccve group, supporting the theory of a combined treatment. a randomized double blind placebo controlled study with a sample size calculation should be performed to confirm our results.
