Web-based access control system
This article describes a web-based system to control and manage the access to the ESTCB, which it is under development as a student’s final project. Beyond an important pedagogical and technological value, we believe that this work is an important step towards offering strong and efficient security management for access control systems. We make use of standard technologies in use on the Web, to make an effective campus-wide security system. The system management and configuration, the consultation of access information for schedules, users, spaces, among others, will be carried out
through the Internet. The proposed model is based on the use of two data nets: a CAN field bus to which are connected magnetic cards readers, door locks and sensors of each access place and the Ethernet that establishes connection between different CAN field bus and servers, which contain information about users and access rules
Web-CAN interface for access control and monitoring
This paper describes a web-based system which allows the user to manage and to do real time monitoring the access to the educational building spaces, using two data nets.
The first one is based on the CAN bus for data acquisition and actuation tasks to which are connected control devices like, magnetic cards readers, door locks and sensors. The second one is an Internet/Intranet infrastructure and uses standard web technologies like PHP and Java to provide an effective control and real time monitoring. This system is implemented on the Linux operating system using the Apache HTTP server and make use of standard technologies in use on the Web, to make an effective campus-wide security system. To close the gap between these two nets we used a CAN/Intranet gateway.
In this paper the system layout and its main components are described
A target environment programming language to improve developer's productivity: a case study
This paper presents a target-specific programming
language (TSL) that was designed to improve the design cycle of
code generation for an industrial embedded system. The native
assembly code, the new language structure and their constructs, are
presented in the paper. The proposed TSL is expressed using words
and terms that are related to the target’s domain and consequently it
is now easier to program, understand and to validate the desired code.
It is also demonstrated the language efficiency by comparing some
code described using the new language against the previous used
code. The design cycle is improved with the usage of the TSL
because description time and debug time are significantly reduced
with this new software tool. This is also a case of university-industry
partnership
Case report: Calcified neurocysticercus, perilesional edema, and histologic inflammation
Here, we present the second report of the histopathology of a Taenia solium calcification giving rise to perilesional edema. This has important implications, because if perilesional edema lesions are inflammatory in character, immunosuppressive or anti-inflammatory medications, not just antiepileptic drugs alone, may be useful to prevent or treat recurring episodes in such patients
Epidemiology of lobomycosis-like disease in bottlenose dolphins <i>Tursiops</i> spp. from South America and southern Africa
We report on the epidemiology of lobomycosis-like disease (LLD), a cutaneous disorder evoking lobomycosis, in 658 common bottlenose dolphins Tursiops truncatus from South America and 94 Indo-Pacific bottlenose dolphins T. aduncus from southern Africa. Photographs and stranding records of 387 inshore residents, 60 inshore non-residents and 305 specimens of undetermined origin (inshore and offshore) were examined for the presence of LLD lesions from 2004 to 2015. Seventeen residents, 3 non-residents and 1 inshore dolphin of unknown residence status were positive. LLD lesions appeared as single or multiple, light grey to whitish nodules and plaques that may ulcerate and increase in size over time. Among resident dolphins, prevalence varied significantly among 4 communities, being low in Posorja (2.35%, n = 85), Ecuador, and high in Salinas, Ecuador (16.7%, n = 18), and Laguna, Brazil (14.3%, n = 42). LLD prevalence increased in 36 T. truncatus from Laguna from 5.6% in 2007-2009 to 13.9% in 2013-2014, albeit not significantly. The disease has persisted for years in dolphins from Mayotte, Laguna, Salinas, the Sanquianga National Park and Bahía Málaga (Colombia) but vanished from the Tramandaí Estuary and the Mampituba River (Brazil). The geographical range of LLD has expanded in Brazil, South Africa and Ecuador, in areas that have been regularly surveyed for 10 to 35 yr. Two of the 21 LLD-affected dolphins were found dead with extensive lesions in southern Brazil, and 2 others disappeared, and presumably died, in Ecuador. These observations stress the need for targeted epidemiological, histological and molecular studies of LLD in dolphins, especially in the Southern Hemisphere
Pharmaceutical topical gel: development and validation of a UV spectrophotometric method for determination of polyphenols
The objective was to develop and validate a method for the determination of total polyphenols in a vaginal gel containing a dried extract of Aroeira (Schinus terebinthifolius Raddi). The method was developed by UV spectrophotometry, and proved to be precise, accurate, reproducible, and easy to perform.Colegio de Farmacéuticos de la Provincia de Buenos Aire
Elephant grass silage inoculated with cellulolytic fungi isolated from rumen
ABSTRACT The objective was to evaluate the inoculation with Aspergillus terreus and/or Trichoderma longibrachiatum on fermentation, chemical and microbiological composition of elephant grass ‘Cameroon’ silage (Cenchrus purpureus). Treatments were A. terreus at 105 colony forming units (CFU)/g (AT15), T. longibrachiatum at 105 CFU/g (TL20), a mixture of both at 105 CFU/g (MIX), and a control group without inoculation (CONTR). The design was completely randomized with seven replicates. The MIX silage was most stable, while CONTR, AT15, and TL20, had lower dry matter losses. There was no effect of inoculation in the chemical composition of silages. Only MIX silage (4.40) had pH above the minimum of 4.2 for humid grass silage and above the control (4.05). Bacteria from Diplococcus genus was identified at the opening of TL20 and CONTR silages. After air exposure, the population of rods, Lactobacillus, and total lactic acid bacteria was higher in theTL20 and MIX. The inclusion of a T. longibrachiatum and A. terreus mixture increases dry mater loss and silage pH. T. longibrachiatum was more efficient in maintaining populations of total lactic acid bacteria after opening; therefore, this strain has potential as an additive for elephant grass ‘Cameroon’ silage
