The mucocele of appendix or mucosecreting tumor is a rare affection defined as a cystic dilatation of the light of the appendix following the intra luminal accumulation of mucinous, translucent, gelatinous, secretion which may reach either the entire organ or a segment more often distal. The pathogenesisis is discussed;the diagnosis is more often preoperative. The therapeutic depends on the histological nature. This goes from the simple appendicectomy, whose shapes are benign to the right hemicolectomy in the malignant mucocele. We report a case collaged in the general surgical service of the 5th Military Hospital.

The Askin tumour is a highly malignant rare tumour with small cells, pertaining to the group of the primitive neuroectodermal tumours. It develops with the costs of the soft parts of the thoracic wall and it’s characterized by extra and endothoracic fast extension. We report seven cases colliged in our service by specifying the role of the imagery in the diagnosis but especially the assessment of extension of these tumours.

Background: The tuberculosis is an endemic disease in our country;it remains a major public health problem. Liver and splenic tuberculosis is a classic disease which represents 1.5% of all gastrointestinal tuberculosis. Patients and Methods: We reported the case of a fifty-six years old patient admitted in the department of surgery for acute cholecystitis, and the biological balance showed a hyperleukocytosis at 16,000 elements/mm3 and a CRP at 25 with a light cholestasis. The abdominal scanner showed a micronodular splenomegaly with coelio mesenteric ganglions. We discovered a tuberculosis location in the liver and the spleen and we realized a cholecystectomy with a hepatic biopsy and a splenectomy. Results: A gallbladder ablation associated with an enlarged spleen and liver biopsy was diagnosed with liver and splenic tuberculosis. The patient was put under anti tubercular treatment with the good clinical and radiological evolution. Conclusion: The diagnosis of tuberculosis should always be considered especially in endemic countries.

The hydatid disease establishes a real problem of public health in our country. The hydatid cyst is preferentially located at the level of the liver and the lungs. Its mediastinal location is extremely rare, representing 0à 4% of all the hydatic locations. The imaging plays an important role in the diagnosis of this affection and in the balance sheet of extension in search of another location. The hydatid cyst also raises a diagnostic problem with the cystic hurts of the mediastinum. We report a case of mediastinal hydatid cyst colliged in the service of general surgery at the 5th military hospital.

Recently, orthogonal moments have become efficient tools for two-dimensional and three-dimensional（2D and 3D） image not only in pattern recognition, image vision, but also in image processing and applications engineering. Yet, there is still a major difficulty in 3D rotation invariants. In this paper, we propose new sets of invariants for 2D and 3D rotation, scaling and translation based on orthogonal radial Hahn moments. We also present theoretical mathematics to derive them. Thus, this paper introduces in the first case new 2D radial Hahn moments based on polar representation of an object by one-dimensional orthogonal discrete Hahn polynomials, and a circular function. In the second case, we present new 3D radial Hahn moments using a spherical representation of volumetric image by one-dimensional orthogonal discrete Hahn polynomials and a spherical function. Further 2D and 3D invariants are derived from the proposed 2D and 3D radial Hahn moments respectively, which appear as the third case. In order to test the proposed approach, we have resolved three issues： the image reconstruction, the invariance of rotation, scaling and translation, and the pattern recognition. The result of experiments show that the Hahn moments have done better than the Krawtchouk moments, with and without noise. Simultaneously, the mentioned reconstruction converges quickly to the original image using 2D and 3D radial Hahn moments, and the test images are clearly recognized from a set of images that are available in COIL-20 database for 2D image, and Princeton shape benchmark（PSB） database for 3D image.

This study evaluates the annual loss of soil in the sub-basin of Oued Haricha (Tahaddart basin, Western Rif, NW Morocco). The integration of revised (RUSLE) and modified (MUSLE) soil loss empirical equations of Wischmeier and Smith in combination with GIS permits the modelling of soil erosion at the scale of parcels. The characteristics of precipitation and runoff, the soil properties, the culture system and the current working practices of soil in the sub-basin of the Oued Haricha are collected from local data. The digital terrain model is used to generate topographic factors. The combination of different RUSLE factors shows that the annual soil is 62.72 t/ha/year and corresponds to an average level of risk. The total losses calculated by MUSLE method are valued at 221,468 t/year. The rates of loss due to linear erosion are 82,652 t/year. These soil losses represent 20.33% of the total losses, and confirm that the losses on the slopes outweigh the losses due to the river system. Sedimentation module shows that the areas of high erosion (greater than 200 t/ha/year) are concentrated in the reliefs with average and high slope and occupy 38% of the total area. The deposition areas occupy the centre of sub-basin and constitute 9.12% of the total area. These deposits were concentrated on the edges of major rivers and the outlet of the sub-basin and contributed to siltation of the April 9, 1947 dam.

We use the Pair Approximation method to analyze the magnetic and magnetocaloric behaviors of diluted mixed spin SA=1 and spin SB=1/2 with the anisotropic Heisenberg model, on a cubic lattice with coordination number z=6. Our system is described in presence of an external magnetic field;the phase diagram and thermodynamic properties related to the concentration of magnetic atom(A or B) and the single ion anisotropy are constructed and *** attention is paid to magnetocaloric properties provided by isothermal entropy change as well as the cooling capacity. These cooling power keys are plotted and discussed as a function of interaction anisotropy and magnetic component concentration of two sublattices ions A and B. Numerical results show a double peak structure in the entropy change curve and the inverse magnetocaloric effect related to the presence of the negative single-ion anisotropy.

A new colorimetric sensor based-azo dye for Cu^2+ detection was synthesized and characterized by FTIR and NMR spectroscopies. The results showed that the azo dye had a high selective and sensitive recognition toward Cu^2+. The solution containing the sensor changed color from pink to pale yellow with a hypsochromic shift in the presence of Cu^2+. The sensor selectivity and sensitivity toward Cu^2+ ions were investigated by colorimetry and UV-Vis spectroscopy. For practical applications, a cellulosic textile test strip for high-selectivity detection of Cu^2+ ions in aqueous solution was developed using the synthesized azo dye as chromogenic chemosensor molecule, while using a solid cellulose textile as a substrate. As a result, a spectacular color change of the test strip was observed do pending on the amount of copper ions in contact with the strip, which allows an estimation of Cu^2+ concentration by naked eye.
