L’inspection spéciale des imp ts et la loi sur la publicité de l’administration
Karim Hachimi
Pyramides : Revue du Centre d'Etudes et de Recherches en Administration Publique , 2012,
Abstract: L’Inspection Spéciale des Imp ts (I.S.I.) est l’administration d’élite du Ministère des Finances. Elle considère que la loi du 11 avril 1994 relative à la publicité de l’administration permet aux contribuables malhonnêtes de prendre connaissance du degré d’information de l’I.S.I. quant à leur situation financière. Cette information leur permet de dissimuler au mieux les informations dont l’I.S.I. ne dispose pas encore et qu’elle s’apprêtait à quérir auprès d’eux. Cet état de fait réduit d’autant le redressement fiscal et l’amende qu’ils encourent. Partant du principe que cette loi réduit son efficacité dans la poursuite d’une éventuelle fraude fiscale, l’I.S.I. a décidé de ne pas appliquer la loi. Il n’y a donc plus de garantie juridique pour le contribuable. L’un d’entre eux a porté l’affaire devant le Conseil d’état en juin 1997. L’arrêt rendu fait aujourd’hui encore jurisprudence.Le but de cette petite étude est de décortiquer les arguments de l’I.S.I. et ceux du Conseil d’état pour en retirer une solution permettant à l’I.S.I. de continuer à fonctionner avec autant d’efficacité, tout en respectant la règle de droit.
Conceptual Analysis and Fieldwork in Macroeconometric Methodology: Modeling Unemployment, Inflation and Production  [PDF]
Karim Errouaki
Technology and Investment (TI) , 2014, DOI: 10.4236/ti.2014.53015
Abstract:

The recent failure of commonly accepted, inductive, econometric models to provide insights into real, macroeconomic phenomenon during economic crises has provoked a debate concerning contemporary econometric methodology. Based on the foundations laid by Haavelmo, and Hollis and Nell, an assessment of Edward J. Nell’s (1998) “unifying methodological framework” (UMF) is offered. Nell’s UMF places socioeconomic institutions and interdependencies, and technological realities as basis of analysis. Using “conceptual analysis” and “fieldwork” Nell presents an alternative to generally accepted, mainstream, econometric methodology. The purpose of this paper is to look at some examples of the way, and this can help develop useful theory and improve macroeconometric model building. Applying Nell’s UMF to unemployment, inflation, and production reveals a methodological advance that promises more realistic insights into macroeconomic phenomena than is offered by contemporary, mainstream, econometric models.

Doubly nonlinear parabolic equations related to the p-Laplacian operator: Semi-discretization
Fatiha Benzekri,Abderrahmane El Hachimi
Electronic Journal of Differential Equations , 2003,
Abstract: We study the doubly nonlinear parabolic equation $$ frac{partialBeta(u)} {partial t}-riangle_p u + f(x,t,u )= 0 quadhbox{in } Omegaimesmathbb{R}^+, $$ with Dirichlet boundary conditions and initial data. We investigate a time-discretization of the continuous problem by the Euler forward scheme. In addition to proving existence, uniqueness and stability questions, we study the long time behavior of the solution to the discrete problem. We prove the existence of a global attractor, and obtain its regularity under additional conditions.
Immunological Manifestations in Paraphenylene Diamine Poisoning  [PDF]
Boubaker Charra, Abdelhamid Hachimi, Abdellatif Benslama, Norddine Habti, Brahim Farouqi, Said Motaouakkil
International Journal of Clinical Medicine (IJCM) , 2011, DOI: 10.4236/ijcm.2011.24072
Abstract: Objective: Our aim is to establish the immunologic profile of PPD-intoxicated persons based on monitoring of the inflammatory reaction. Methods and patients: A prospective study of 21 patients hospitalized in a medical ICU with PPD intoxication during 2010. A follow-up of demographic, clinical, paraclinical, therapeutic and evolutive parameters as well as evaluation of the scores of gravity (SAPS II, APACHE II, OSF) was carried out in all our patients, and an inflammatory check-up (white blood cell, Creactive protein, C3 and C4 fractions of complement and lymphocyte subpopulations CD3, CD4, CD8 and CD19) was realized for all patients. The kinetic of these parameters was compared with clinical and paraclinical evolution. Results: The monitoring of the inflammatory reaction in our patients shows an evolution at three times for this reaction, with the first time of inflammatory stress during the first 3 days after the intoxication characterized by a relative immunodepression, the second time from the third day when the rhabdomyolysis exerts its pro-inflammatory power and the third time (from the sixth day) corresponds to the immunomodulative action of PPD and to its oxidative metabolism. It’s a systemic and specific inflammatory reaction to a cytotoxic cell support, which would explain the secondary worsening of the clinical and paraclinical parameters of our patients (hemodynamic shock, multivisceral failure, etc.). Conclusion: It seems that the immunological aspect may present the answer to several questions that rhabdomyolysis alone could not answer during PPD-poisoning. This study tried to establish a first immunologic profile of PPD-intoxicated persons, and to correlate it with their evolution.
Semidiscretization for a nonlocal parabolic problem
Abderrahmane El Hachimi,Moulay Rchid Sidi Ammi
International Journal of Mathematics and Mathematical Sciences , 2005, DOI: 10.1155/ijmms.2005.1655
Abstract: A time discretization technique by Euler forward scheme is proposed to deal with a nonlocal parabolic problem. Existence and uniqueness of the approximate solution are proved.
Accidental organophosphate insecticide intoxication in children: a reminder
Willemijn van Heel, Said Hachimi-Idrissi
International Journal of Emergency Medicine , 2011, DOI: 10.1186/1865-1380-4-32
Abstract: Management of organophosphate poisoning consists of airway management, administration of oxygen and fluid, as well as atropine in increasing doses and pralidoxime. Decontamination of the patient's skin and the removal of the patient's clothes are mandatory in order to avoid recontamination of the patient as well as the surrounding healthcare personnel.Plasma pseudocholinesterase analysis is a cheap and an easy indicator for organophosphate insecticides intoxications and could be used for diagnosis and treatment monitoring.Organophosphate insecticides are widely used in rural areas. Intentional ingestion of organophosphates is associated with a high mortality rate [1]. Organophosphate intoxication (OI) induces irreversible inhibition of acetylcholinesterase. Organophosphates phosphorylate the serine hydroxyl group of acetylcholine, leading to accumulation of acetylcholine at the cholinergic synapses [2]. This accumulation leads to weakness and fasciculation of the muscle. In the central nervous system, neural transmission is disrupted. If this blockade is not reversed within 24 h, large amounts of acetylcholinesterase are permanently destroyed [3].Acetylcholinesterase is found in red blood cells as well as in nicotinic and muscarinic receptors. To determine the severity and/or the elimination time of OI, one should measure cholinesterase in blood, either by measuring plasma pseudocholinesterase (PCE) or by measuring the cholinesterase in erythrocytes (which is thought to reflect the cholinesterase in neurons and neuromuscular junctions). The first method is widely available and therefore commonly used [3,4].Herein, we report a case of siblings who, upon being sprayed with an organophosphate solution, developed severe OI associated with central nervous system (CNS) depression.A 7-year-old previously healthy boy was brought into the emergency department with vomiting and reduced consciousness by his mother. He had been in good health until he was found, 30 min prior to
Existence and regularity of a global attractor for doubly nonlinear parabolic equations
Abderrahmane El Hachimi,Hamid El Ouardi
Electronic Journal of Differential Equations , 2002,
Abstract: In this paper we consider a doubly nonlinear parabolic partial differential equation $$ frac{partial eta (u)}{partial t}-Delta _{p}u+f(x,t,u)=0 quad hbox{in }Omega imesmathbb{R}^{+}, $$ with Dirichlet boundary condition and initial data given. We prove the existence of a global compact attractor by using a dynamical system approach. Under additional conditions on the nonlinearities $Beta$, $f$, and on $p$, we prove more regularity for the global attractor and obtain stabilization results for the solutions.

Abderrahmane El Hachimi,Moulay Rachid Sidi Ammi
Electronic Journal of Differential Equations , 2002,
Abstract: problem with degeneracy by using a regularization and truncation process. The solution of the regularized-truncated problem is obtained by using Schauder's fixed point theorem. Then the solutions of the thermistor problem are obtained by applying the monotonicity-compacity method of Lions.
Existence of stable periodic solutions for quasilinear parabolic problems in the presence of well-ordered lower and upper-solutions
Abderrahmane El Hachimi,Abdelilah Lamrani Alaoui
Electronic Journal of Differential Equations , 2002,
Abstract: We present existence and stability results for periodic solutions of quasilinear parabolic equation related to Leray-Lions's type operators. To prove existence and localization, we use the penalty method; while for stability we use an approximation scheme.
