The present invention refers to a system for the heuristic computing of cardiac performance temporal parameters and application method thereof, for the possibility of processing electrical signals from the heart and estimate in real time the temporary parameters of each heartbeat, meaning the time lengths, P_L, QRS_L, and T_L the time slots, PQ_S and ST_S the time intervals, PQ_I, QT_I, RR_I, the time at point J, frequency and cardiac rhythms. Said parameters are highly useful in the clinical diagnosis of heart disorders in humans, particularly when is possible to consult it in a local and remote form (medical telemetry) by electronic devices such as electrocardiographic equipment, smart phones, tablets or personal computers. MONTMORILLONITE BLOCKS FOR HEAVY METALS ADSORPTION IN WATER BY BENTONITE AND FLY ASH The present invention describes a bentonite composite material and a sol-gel silica alkaline solution as a binder, of relatively light weight, capable of adsorbing heavy metals present in water. Said material is composed mostly of expanding clay which maintains it intact when inmersion.To afford this effect, the lightweight, porous and water permeable material receives a heat treatment of up 400°C to 1400°C, thus giving rigidity and resistance to lower impacts and allowing to acquire the insolubility property when immersed. The aforementioned material possess a density of up 700 kg/m3 to 1,500 kg/m3 and a compressive resistance in the range of up 12 kg/cm2 to 16 kg/cm2. The material is related primarily to the metal-mechanic and mining industries effluent sanitation, as well as natural contamination of surface and subterranean waters. The heavy metal ion adsorbent material may include fly ash and/or zeolites to supplement the adsorption capacity, as well as embossments of volcanic ori gin as coarse aggregate, as a porous material that can provide water permeability and reduce costs acting as filler particles. The preparation method no requires high energy consu
