Abdalla-Filho, Elias;Bertolote, José Manoel;
Revista Brasileira de Psiquiatria , 2006, DOI: 10.1590/S1516-44462006000600002
Abstract: objective: the study aims to approach forensic psychiatry within different contexts. it endeavors to show how this specific psychiatry science area is influenced by legal and cultural aspects. method: the bibliography reviewed had in view understanding the different ways of how to deal with law within the psychiatric sphere, from a cultural point of view. results: there is a great heterogeneity, of different nature (legal, political, cultural, and religious) that enrich, but at the same time makes difficult, a debate about this issue. conclusions: there are two great obstacles to achieve a good knowledge about the practice of forensic psychiatry all over the world. the first one is represented by a heterogeneity that makes difficult its description in a comprehensible way. the second is the lack of knowledge of the cultural diverse realities. these difficulties should be a stimulus for newer studies of this characteristic. only in this way it becomes possible to gradually increase the comprehension of this issue.
Legisla??o relativa à saúde mental: revis?o de algumas experiências internacionais
Bertolote,José M.;
Revista de Saúde Pública , 1995, DOI: 10.1590/S0034-89101995000200013
Abstract: the main areas dealt with by current mental health legislation, worldwide, are reviewed. these areas concern mainly: (i) rights of the mentally ill (right to care and human rights), (ii) quality of care, (iii) the use of administrative and budget control measures, and (iv) consumer participation and involvement in the organization and management of mental health care services. the evolution of international legislation (particularly united nations declarations, covenants and resolutions) relative to people with mental disorders are described on the basis of up-to-date examples of legal models from different jurisdictions throughout the world. the main current trends are identified and alternatives are advanced for the respect of the human rights of these people and for the improvement of their care. the basis for these proposed alternatives is to be found in the recently approved united nations general assembly resolution on "the protection of persons with mental illness and the improvement and the improvement of mental health care". this resolution is described and discussed in some detail.

Upper Cervical Spine Infection. Complication of Hypopharyngeal Injury  [PDF]
Ghassan Skaf, Elias Elias
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2016, DOI: 10.4236/ijohns.2016.52016
Abstract: Background: We describe a rare case of Candida albicans retropharyngeal infection with upper cervical spondylodiscitis associated with epidural abscess triggered by ingestion of a chicken bone. Case Description: A 63-year-old woman presented with posterior neck and bilateral shoulders pain three weeks after choking on a 2-centimeter chicken bone. Magnetic resonance imaging (MRI) revealed spondylodiscitis and epidural abscess with significant spinal cord compression at C2 and C3 levels. A Barium swallow showed a focal disruption of the posterior wall of the esophagus. A posterior upper cervical fixation (C2-C5) was initially performed. One week later an anterior decompressive procedure was carried out followed by iliac crest bony fusion, and repair of the esophageal defect. Intra-operative cultures showed heavy growth of Candida albicans. After a transitory post-operative neurologic worsening, and after six weeks of appropriate antifungal therapy, the patient achieved a full clinical and radiologic recovery. Conclusion: Prompt surgical debridement, fusion and stabilization combined with adequate antimicrobial agents are necessary to guarantee a good outcome and reverse the neurological deficits.
Minimizing Complementary Pivots in a Simplex-Based Solution Method for a Quadratic Programming Problem  [PDF]
Elias Munapo
American Journal of Operations Research (AJOR) , 2012, DOI: 10.4236/ajor.2012.23037
Abstract: The paper presents an approach for avoiding and minimizing the complementary pivots in a simplex based solution method for a quadratic programming problem. The linearization of the problem is slightly changed so that the simplex or interior point methods can solve with full speed. This is a big advantage as a complementary pivot algorithm will take roughly eight times as longer time to solve a quadratic program than the full speed simplex-method solving a linear problem of the same size. The strategy of the approach is in the assumption that the solution of the quadratic programming problem is near the feasible point closest to the stationary point assuming no constraints.
A Novel Process for the Study of Breakage Energy versus Particle Size  [PDF]
Elias Stamboliadis
Geomaterials (GM) , 2013, DOI: 10.4236/gm.2013.33013
Abstract: The energy size relationship is examined, either as the specific energy required breaking a particulate material from an initial size d1 to a final size d2, where d is usually the d80 size, or as the specific energy required to break a single particle. The present work uses the results obtained using a controlled frequency centrifugal crusher to crush particles of a predetermined size class under different rotation frequencies related to the kinetic energy of the particles at the moment of crushing. The paper calculates the relationship between the rotation frequency and the kinetic energy of the particles before crushing and examines the size distribution of the products. The study results allow presenting the relationship between the kinetic energy of the particles and the mass of particles produced below the initial size class. The work also produces the optimum mathematical model that describes this relationship among three proposed ones. According to this model one can calculate the energy required breaking half of the initial mass below the initial size class and the corresponding specific energy is appointed to the average size of the class. The parameters of the mathematical model can be used to compare the grindability of the different materials. The process can be used as an alternative to the drop weight technique used so far for the study of the breakage energy of minerals and rocks.

Solving the Binary Linear Programming Model in Polynomial Time  [PDF]
Elias Munapo
American Journal of Operations Research (AJOR) , 2016, DOI: 10.4236/ajor.2016.61001
Abstract:

The paper presents a technique for solving the binary linear programming model in polynomial time. The general binary linear programming problem is transformed into a convex quadratic programming problem. The convex quadratic programming problem is then solved by interior point algorithms. This settles one of the open problems of whether P = NP or not. The worst case complexity of interior point algorithms for the convex quadratic problem is polynomial. It can also be shown that every liner integer problem can be converted into binary linear problem.

Early detection of sudden cardiac death by using classical linear techniques and time-frequency methods on electrocardiogram signals  [PDF]
Elias Ebrahimzadeh, Mohammad Pooyan
Journal of Biomedical Science and Engineering (JBiSE) , 2011, DOI: 10.4236/jbise.2011.411087
Abstract: Early detection of sudden cardiac death may be used for surviving the life of cardiac patients. In this paper we have investigated an algorithm to detect and predict sudden cardiac death, by processing of heart rate variability signal through the classical and time-frequency methods. At first, one minute of ECG signals, just before the cardiac death event are extracted and used to compute heart rate variability (HRV) signal. Five features in time domain and four features in frequency domain are extracted from the HRV signal and used as classical linear features. Then the Wigner Ville transform is applied to the HRV signal, and 11 extra features in the time-frequency (TF) domain are obtained. In order to improve the performance of classification, the principal component analysis (PCA) is applied to the obtained features vector. Finally a neural network classifier is applied to the reduced features. The obtained results show that the TF method can classify normal and SCD subjects, more efficiently than the classical methods. A MIT-BIH ECG database was used to evaluate the proposed method. The proposed method was implemented using MLP classifier and had 74.36% and 99.16% correct detection rate (accuracy) for classical features and TF method, respectively. Also, the accuracy of the KNN classifier were 73.87% and 96.04%.
Ciprofloxacin Cardiotoxicity and Hepatotoxicity in Humans and Animals  [PDF]
Elias Adikwu, Nelson Brambaifa
Pharmacology & Pharmacy (PP) , 2012, DOI: 10.4236/pp.2012.32028
Abstract:

Ciprofloxacin is generally well tolerated; the most common adverse effects include gastro intestinal tract, central nervous system and hematological system effects. Recently rising cases of Ciprofloxacin associated toxicity have been reported. Experiment using animal models and clinical experience showed that Ciprofloxacin induced cardiotoxicity is marked by increase QT and QTC interval and prolonged action potential duration. This increases the risk of arrhythmia (tosarde de pointes). Ciprofloxacin induced cardiotoxic effect could be associated with blocking cardiac voltage—gated potassium channels particularly the rapid component (IKr) of the delayed rectifier potassium current. Drug interaction with inhibitors of Cytochrome P450 (CYP) mediated metabolism could be one of the underlying mechanisms. Several cases of Ciprofloxacin induced hepatoxicity have been also reported. These were characterized by extensive hepatocellular necrosis, mixed inflammatory infiltrate and abundant esinophils in the liver. Elevated liver enzymes which include serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and gramma-glutamyltranferase
