Abstract:

Currently, the development of research around VoIP experiences a tremendous growth. In the community of open source Asterisk represents a reliable alternative for a lower cost solution. In this same community as the SIP protocol is a supplement to the more asterisk PBX. To share the benefits claimed by proponents of free software co-existence with other Asterisk server is not yet proven. In this context this paper we show a comparison of the use of simplified resource material for the apache server using the HTTP protocol and server that uses the asterisk SIP.

Abstract:

Voice over IP (VoIP) is a set of software and hardware technologies used for making voice calls over the Internet. VoIP has been massively deployed in corporative environments since voice and data network convergence enables unified communication services while reducing costs. The main component of a VoIP network infrastructure is the private branch exchange (PBX). Nowadays, Asterisk is the most widespread PBX deployed within corporations due to its open access technology, along with its modular and flexible design. The configuration of PBX systems usually relies on multiple configuration file

Abstract:

Las condiciones climáticas del Medio Oeste brasileño restringen el cultivo de la papa a períodos del año en que la humedad del aire es más baja y las temperaturas más cálidas. Por lo tanto, la siembra de papa está restringida a los meses de abril y mayo, lo que proporciona a las plantas las condiciones ideales de desarrollo en un período de mayor susceptibilidad a Ralstonia spp. (Rs), que presenta un mejor desarrollo en condiciones de alta humedad del aire y temperatura. Este trabajo tuvo como objetivo evaluar la adaptación de los genotipos de papa de Embrapa a las condiciones edafoclimáticas

Abstract Context.—In the normal course of activity, pathologists create and archive immense data sets of scientifically valuable information. Researchers need pathology-based data sets, annotated with clinical information and linked to archived tissues, to discover and validate new diagnostic tests and therapies. Pathology records can be used for research purposes (without obtaining informed patient consent for each use of each record), provided the data are rendered harmless. Large data sets can be made harmless through 3 computational steps: (1) deidentification, the removal or modification

Abstract:

Intracytoplasmic sperm injection (ICSI) is used for assisted fertilization of equine oocytes. However, not all oocytes cleave after ICSI. Maternal aging deleteriously affects fertility in mares and women, with reduced oocyte quality and success of assisted reproductive technologies. In the oocyte, senescence and cell-programmed death begins after maturation; the extent that maternal age affects these events is unknown. We hypothesised that formation of α/β tubulin asters and f-actin bubbles are associated with aging of the oocyte in vitro and/or aging of the oocyte in vivo, in aged donors. In

Abstract:

An outbreak of a new potato disease occurred in Texas and Nebraska causing a serious defect in potato chips produced from commercial processing potatoes. The defect consists of patchy brown discoloration of chips and can be a cause for rejection of contracted potatoes by the processor. Infected potato plants exhibit symptoms of the purple top wilt syndrome similar to those of the purple top disease in processing potatoes caused by clover proliferation phytoplasma recently found in Washington and Oregon (3). Foliar symptoms include stunting, chlorosis, slight purple coloration of new growth, sw

Objectives: In this study we have made an attempt to establish torque value of the muscles rotating the knee of patients who had ruptured their ACLs during an amateur football practise on an artificial turf. In this study we presented biomechanical research on torques of muscles responsible for internal and external rotation of the lower leg. We presented a method whereby it is possible to measure the muscle strength before and after the ACL rupture but also during the process of rehabilitation and after its finish. The available literature on measurements of torque of the knee is quite extens

Background:In systemic sclerosis (SSc), inflammation and microvascular damage are fundamental in the progressive fibrotic process. Although the presence of accelerated atherosclerosis in SSc is not as well-described as in other systemic disorders namely rheumatoid arthritis, it appears that individuals suffering from the disease are at higher risk for cardiovascular events.

Abstract Abstract 633 Type 2 diabetes mellitus (T2DM) patients have increased incidence of acute vascular events, due in part to a prothrombotic/proinflammatory state with elevated plasma coagulation factors and enhanced platelet responsiveness. The hallmarks of T2DM, hyperglycemia (HG) and hyperinsulinemia (HI), are independent risk factors for mortality but their contributions to the prothrombotic mechanisms are unclear. Our prior studies in healthy non-diabetic subjects using infusion clamps showed that selective HI and HG, and more so the combination of HI+HG, increased circulating membran

Abstract Introduction Proposed landmarks to predict the anatomical location and trajectory of the sigmoid sinus have varying degrees of reliability. Even with neuronavigation technology, landmarks are crucial in planning and performing complex approaches to the posterolateral skull base. By combining two major dependable structures—the asterion (A) and transverse process of the atlas (TPC1)—we investigate the A-TPC1 line in relation to the sigmoid sinus and in partitioning surgical approaches to the region. Methods We dissected six cadaveric heads (12 sides) to expose the posterolateral skull
