Computer hardware is in great demand by the hobies and assembler, Karen canchoose their own hardware is required in accordance with the needs and abilities.However, in choosing computer hardware, the price is not always a major factor inthe quality of the computer hardware. The author tries to help by providinginformation on computer hardware that can be used as a material consideration.Based on the results of a questionnaire distributed by the author, the constraints facedtoday is the hobies and assemblers feel difficulty in choosing a motherboard andknow the price of computer hardware.Using Microsoft FrontPage 2000, the authors make a home page for information oncomputer hardware in Indonesian language. So that the hobies and assembler canview this information through the internet media.As there are several things that must be considered by the webmaster in designinghome pagedengan using Microsoft FrontPage 2000, which hit counters, search formsand guest book. We make this information, the assembler can know hobies andhardware information and the price of hardware
Pulsatile tinnitus - Case report of duralarteriovenous fistula and review of the literature
O acufeno é definido como uma percepção consciente de um som na ausência de fonte externa. Embora não seja considerado uma doença, muitos doentes sofrem deste sintoma. Tem múltiplas etiologias sendo que, apenas algumas são conhecidas. As malformações vasculares constituem a principal causa de acufenos pulsáteis. Descrevem-se dois casos clínicos de doentes com acufeno pulsátil. Ambos realizaram angio-ressonância que evidenciou fístula arteriovenosa dural (DAVF) do seio lateral direito, uma do tipo I e outra do tipo IIa de Cognard. Foram submetidas a angiografia crânioencefálica com embolização, recorrendo a partículas de polivinil álcool (PVA) e a Onyx®, com encerramento da fístula e resolução das queixas. O tratamento das fístulas arteriovenosas durais deve ser ponderado de acordo como tipo de fístula, segundo as escalas de Cognard ou de Borden e, com a existência ou não de sintomatologia.info:eu-repo/semantics/publishedVersio
Treatment of tumour recurrence after resection of hepatocellular carcinoma. Analysis of 97 consecutive patients
OBJECTIVE:
To evaluate the long-term results of aggressive treatment of HCC recurrence.
METHODS:
Two hundred and nine consecutive patients underwent hepatic resection for HCC in our hospital. Tumour recurrence was diagnosed in 97 (51%) of the 190 patients with curative resection. Sixteen underwent hepatic resection: two right hepatectomies, one three-segmentectomy, one left hepatectomy, five two-segmentectomies, six segmental resections and one subsegmentectomy. Two patients with metastasis in the spine were submitted to a vertebral body resection. Twenty-five patients were treated with percutaneous ethanol injection or intra-arterial chemoembolization. Fifty-four patients with a poor performance status and liver function or multiple extra hepatic recurrences did not receive any treatment.
RESULTS:
There were no operative deaths. The postoperative mortality rate was 5.5% (one patient). The cumulative overall survival after the second resection was respectively 89%, 46% and 31% at 1, 3 and 5 years. There was a significant difference in survival between patients treated with repeat resection and those submitted to a non-surgical or conservative treatment (p<0.0001). There were no differences in operative deaths, postoperative mortality and morbidity between the first and second hepatic resection.
CONCLUSIONS:
Aggressive management with combined resection or loco regional therapy for intrahepatic recurrence and resection of isolated extra-hepatic recurrence may offer long-term survival in selected patients. Second liver resection for recurrence of HCC can be safely performed

Deep learning networks for olive cultivar identification: a comprehensive analysis of convolutional neural networks
Deep learning networks, more specifically convolutional neural networks, have shown a notable distinction when it comes to computer vision problems. Their versatility spans various domains, where they are applied for tasks such as classification and regression, contingent primarily on the availability of a representative dataset. This work explores the feasibility of employing this approach in the domain of agriculture, particularly within the context of olive growing. The objective is to enhance and facilitate cultivar identification techniques by using images of olive tree leaves. To achieve this, a comparative analysis involving ten distinct convolutional networks (VGG16, VGG19, ResNet50, ResNet152-V2, Inception V3, Inception ResNetV2, XCeption, MobileNet, MobileNetV2, EfficientNetB7) was conducted, all initiated with transfer learning as a common starting point. Also, the impact of adjusting network hyperparameters and structural elements was explored. For the training and evaluation of the networks, a dedicated dataset was created and made available, consisting of approximately 4200 images from the four most representative categories of the region. The findings of this study provide compelling evidence that the majority of the examined methods offer a robust foundation for cultivar identification, ensuring a high level of accuracy. Notably, the first nine methods consistently attain accuracy rates surpassing 95%, with the top three methods achieving an impressive 98% accuracy (ResNet50, EfficientNetB7). In practical terms, out of approximately 2016 images, 1976 were accurately classified. These results signify a substantial advancement in olive cultivar identification through computer vision techniques.This work was carried out under the Project “OleaChain: Competências

The African hind's (Cephalopholis taeniops, serranidae) use of artificial reefs off Sal Island (Cape Verde): a preliminary study based on acoustic telemetry
The African hind Cephalopholis taeniops (Valenciennes, 1828) is one of the most important commercial demersal species caught in the Cape Verde archipelago. The species is closely associated with hard substrate and is one of the main attractions for SCUBA divers. In January 2006 a former Soviet fishing vessel - the Kwarcit - was sunk off Santa Maria Bay (Sal Island). Young C. taeniops are commonly observed in this artificial reef (AR). In order to investigate the species' use of the AR, 4 specimens were captured and surgically implanted underwater with Vemco brand acoustic transmitters. The fish were monitored daily with an active telemetry receiver for one week after release. Simultaneously, an array of 3 passive VR2 / VR2W receivers was set for 63 days, registering data that allowed an analysis of spatial, daily and short term temporal activity patterns. The results showed site fidelity to the AR, with no migrations to the nearby natural reef. The method used allowed to register a consistent higher activity during daytime and a preference for the area opposite the dominant current
Build orientation optimization of car hoodvent with additive manufacturing
Additive manufacturing is a widely used process consisting in the
building of a three-dimensional (3D) object from a model projected on a computer, adding the material layer-by-layer. This technology allows the printing of
complex shape objects and is being increasingly adopted by the aircraft industry,
medical implants, jewelry, footwear, automotive, fashion products, among others.
The build orientation optimization of 3D models has a great influence on costs
and surface quality when printing three-dimensional objects.
In this work, three build orientation optimization problems are studied: single objective problem, bi-objective problem and many-objective problem. To this
end, three quality measures are applied: the support area, the build time and the
surface roughness, for the Car Hoodvent model. First, a single-objective optimization problem is presented and solved by the genetic algorithm, obtaining
optimal solutions for each objective function. Then, the study of the bi-objective
optimization problem is carried out for each pair of two objectives and some
representative trade-off solutions are identified. Finally, the study of the many objective optimization problem, considering the three measures optimized simultaneously, is presented with some more optimal solutions found. The bi-objective
and many-objective problems are solved by a multi-objective genetic algorithm.
For a better analysis and comparison of the solutions found, the Pareto fronts are
used, enabling a better visualization of the solutions between the objectives. This
study aims to assist the decision-maker in choosing the best part print orientation
angles according to his/her preferences. The optimal solutions found confirmed
the effectiveness of the proposed approach.info:eu-repo/semantics/publishedVersio
