The question is about a prospective study carried on along 12 months from 1st January, to December 31, 2013. It implicated 83 diabetes patients known or unknown admitted at the casualty department for an acute metabolic complication. In total the frequency of acute metabolic complications of diabetes mellitus that have been essentially done through the ketoacidosis model (73.49%) and hypoglycaemic (26.5%) is of 23.38%. Majority of diabetes patients were of type 2 (68.66%) and aged 50 and over with a sex-ratio of 0.76. The ketoacidosis revealed the disease in 43.37% cases. The main factors of ketoacidosis decompensations were infections, treatment termination and myocarditis ischaemia. Hypoglycemia decompensation factors were due to the absence or deficiency of food, the overdosage. Metabolic complications of diabetes then remain frequent. Infection and treatment termination are the major factors of ketoacidosis decompensation whereas those of the absence or deficiency of food are that of hypoglycemia. The prevention is compulsory through early screening of the disease and high treatment awareness of diabetes patients.展开更多

The system is mainly composed of soft mobile mechanism for earthworm locomotion and turning mechanism based on shape memory effect. The soft mobile mechanism contacts colon wall with air in inflatable balloons, so the robot has better soft and non invasive properties. The turning mechanism can be actively bent by shape memory alloy components. It ensures the colonoscope to adapt to the tortuous shape of colon. Some experiment results are given in the paper.展开更多

In this work the yield of alloying elements and the removal of the impurities nitrogen, sulphur and phosphorus as a result of electroslag refining (ESR) in a newly developed CrNiMoWMnV ultrahigh-strength steel (UHSS) have been studied in relation to their activities in the molten metal pool. Six experimental heats of CrNiMoWMnV UHSS with different chemical compositions were designed, melted in an induction furnace (IF) and refined using ESR. This was followed by hot forging of the ingots at 1100°C to 950°C. ESR using a CaF2-CaO-Al2O3 slag system led to a high yield in Cr, Ni, Mo, W, Mn and V, while the yield of Si is low. The desulphurization of all six UHSS grades was pronounced with most of the sulphur removed either to the slag or by gas reactions. The degree of dephosphorization was only 5% irrespective of the steel composition. On the other hand, denitrification (removal of nitrogen) was achieved. It ranged from 8% to 63% depending on the steel composition. The yield of the alloying elements and removal of impurities from the steel during ESR depends on the chemical and physical properties of the ESR slag and the activity of the elements in the molten state, taking into account elemental interactions.展开更多

The porous medium is both anisotropic in permeability whose principal axes are oriented in a direction that is oblique to the gravity vector and in thermal conductivity with principal directions coincident with the coordinate axes. The Beavers-Joseph condition is applied at the interface between the two layers. Based on parallel flow approximation theory, a linear stability analysis is conducted to study the geothermal river beds system and documented the effects of the physical parameters describing the problem. The critical Rayleigh numbers for both the fluid and porous layers corresponding, to the onset of convection arising from sudden heating and cooling at the boundaries are also predicted. The results obtained are in agreement with those found in the past for particular isotropic and anisotropic cases and for limiting cases concerning pure porous media and for pure fluid layer. It has demonstrated that the effects of anisotropic parameters are highly significant.展开更多
