biomass co-firing with lignite represents an attractive solution for operating lignite-fired thermalpower plants (tpp) with the dual advantage of using local renewable resources and simultaneously reducingemissions. the subject of this study is technical and environmental investigation of the feasibility of the cofiring of soma lignite with some dried agricultural residues in the soma thermal p...

The usage possibility of 19 composites raw refractory clays from Serbia containing approximately 53.29% SiO2 and 26.73% Al2O3 is presented. sum fluxing oxides was 57.74%, while these materials contained 32% quartz, 29% kaolinite 26% illite–mica. Dilatometry tests revealed a sudden shrinkage with the peak at 1115 °C, owing to formation mullite. refractoriness in range 1581–1718 which classifies ...

It has been reported that the anterior cingulate cortex (ACC) has a variety of functions relating to pain as well as pain perception. However, the underlying mechanisms for those functions remain unclear. To elucidate the functional role of the ACC in pain perception and pain-related functions such as attention to pain and escape from pain, single neuronal activity was recorded from the ACC, an...

EISENMAN, J. S. Pyrogen-induced changes in the thermosensitiuity of septal and preoptic neurons. Am. J. Physiol. 216(Z): 330-334. 19697Single-unit responses were studied in urethan-anesthetized cats. Highly thermosensitive, preoptic cells (Qro > Z), the presumed central thermodetectors, responded to bacterialpyrogen (Piromen) injection (2-3 pg/kg, iv) with a decrease in thermosensitivity, witho...

A summary of the most recent and important measurements in b physics is presented. The production of beauty particles in Z decays, b quark couplings, lifetimes, B-B0 oscillations, semileptonic b decays and studies of the number of charm quarks produced in b decays are reviewed. Extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements |Vtd|, |Vcb|, |Vub| and implication for |Vts| are di...

The purpose of the present study was to evaluate the effect of cooling rates after firing procedures of veneering porcelain on shear bond strength between veneering porcelain and a zirconium dioxide (zirconia; ZrO₂) ceramic material. A total of 48 ZrO₂ disks were divided equally into three groups. Two veneering porcelains that are recommended for ZrO₂ material - Cerabien ZR (CZR), IPS e.max Cer...

Mammalian cold thermoreceptors encode steady-state temperatures into characteristic temporal patterns of action potentials. We propose a mechanism for the encoding process. It is based on Plant's ionic model of slow wave bursting, to which stochastic forcing is added. The model reproduces firing patterns from cat lingual cold receptors as the parameters most likely to underlie the thermosensiti...

We utilized an in vitro adult mouse extensor digitorum longus (EDL) nerve-attached preparation to characterize the responses of muscle spindle afferents to ramp-and-hold stretch and sinusoidal vibratory stimuli. Responses were measured at both room (24°C) and muscle body temperature (34°C). Muscle spindle afferent static firing frequencies increased linearly in response to increasing stretch le...
