A first-half combustion period, for example, is estimated/evaluated, with a required accuracy, more simply than the conventional art, while reducing man-hours to produce a heat generation rate waveform of an internal combustion engine. Within a combustion period of an air-fuel mixture, a period from an ignition time FA to a heat generation rate maximum time dQpeakA where the heat generation rate is maximum is defined as the first-half combustion period a that is one of characteristic values of the heat generation rate waveform. The first-half combustion period a is estimated based on an in-cylinder volume at the heat generation rate maximum time, and furthermore by being corrected using an exponential function of the engine rotation speed with a value depending on a tumble ratio as exponent. Thus, the heat generation rate waveform is produced using the estimated first-half combustion period a.

Viruses and other bioagents are of high medical and biodefense concern and their detection at concentrations well below the threshold necessary to cause health hazards continues to be a challenge with respect to sensitivity, specificity, and selectivity. Ideally, assays for accurate and real time detection of viral agents and other bioagents would not necessitate any pre-processing of the analyte, which would make them applicable for example to bodily fluids (blood, sputum) and man-made as well as naturally occurring bodies of water (pools, rivers). We describe herein a robust biosensor that combines the sensitivity of surface acoustic waves (SAW) generated at a frequency of 325 MHz with the specificity provided by antibodies and other ligands for the detection of viral agents. In preferred embodiments, a lithium tantalate based SAW transducer with silicon dioxide waveguide sensor platform featuring three test and one reference delay lines was used to adsorb antibodies directed against Coxsackie virus B4 or the negative-stranded category A bioagent Sin Nombre virus (SNV), a member of the genus Hantavirus, family Bunyaviridae, negative-stranded RNA viruses. Rapid detection (within seconds) of increasing concentrations of viral particles was linear over a range of order of magnitude for both viruses, although the sensor was approximately 50×104-fold more sensitive for the detection of SNV. For both pathogens, the sensor's selectivity for its target was not compromised by the presence of confounding Herpes Simplex virus type 1. The biosensor was able to detect SNV at doses lower than the load of virus typically found in a human patient suffering from hantavirus cardiopulmonary syndrome (HCPS). Further, in a proof-of-principle real world application, the SAW biosensor was capable of selectively detecting SNV agents in complex solutions, such as naturally occurring bodies of water (river, sewage effluent) without analyte pre-processing.

The modular platform for offshore constructions, composed of more than two separate buoyancy elements partially immersed in water, which move along with the water wave movement and which, in the part above the water level, are connected to the structural elements forming a rigid horizontal spatial structure, characterized in that the buoyancy element (1) is given the shape of a cuboid or cylinder having at least one vertical hollow (2) to accommodate the structural element, i.e. piston (3), which forms the axis along which the buoyancy element (1) moves, and which is connected to the horizontal structural element (4) fitted to take external loads.

A machine (1) and a method for thermobonding using an emission of electromagnetic waves (13), for example microwaves, to activate one or a plurality of adhesive layers located between a support and one or a plurality of layers of flexible covering, through a bed of particles (4) fluidized by a humidified gas. A multi-layer upholstery item including at least one non-permeable layer and produced in a single operation is also described.

A few weeks ago, Reveal host Al Letson jumped in to protect someone who was being attacked by counter-protesters in Berkeley, California. We found the man behind the attack. He says he’s a member of antifa and is taking the fight to white nationalists. We also interviewed rally organizers who are connected to right-wing extremists.  

In the aftermath of the violence at a white supremacist rally in Charlottesville, Virginia, militants from the left and the right are taking their battles to the streets. This week on Reveal, we examine who they are and whether they’re hurtling the country toward more civil strife.
