The research was carried out in order to develop a method for skipping fuel supplies (turning off individual piston strokes) at low frequencies of crankshaft rotations and partial engine operating modes with direct-acting supply systems increase efficiency. developed is easily implement using ring-type discharge valve electronic control. A made the form split elastic ring installed high-pressur...

The gas pressure in the main network of transmission lines is about 700 to 1000 psi (4826.33 6894.76 kPa), which reduced 250 (1723.69 kPa) at entrance station a city. This reduction process, occurs regulator, causes severe drop temperature. temperature produces hydrates and even water vapor freeze. As result, there possibility that passage regulator blocked flow cut off. By employing heaters (i...

background: stevia rebaudiana bertoni, an important anti-diabetic medicinal plant, becomes an inevitable alternative to sugar. due to the propagation difficulties, tissue culture is the best alternative for rapid mass propagation of stevia plants. objective: the present study was conducted to optimize a protocol for rapid micropropagation of stevia rebaudiana by shoot tip explants and to invest...

The bacterial flagellar motor is a reversible rotary machine that rotates a left-handed helical filament, allowing bacteria to swim toward a more favorable environment. The direction of rotation reverses from counterclockwise (CCW) to clockwise (CW), and vice versa, in response to input from the chemotaxis signaling circuit. CW rotation is normally caused by binding of the phosphorylated respon...

Recent findings in atrial natriuretic peptide (ANP) transgenic and gene knockout mouse models uncovered a tonic vasodilatory effect of this hormone that contributes to chronic blood pressure homeostasis. With elevated salt intake, ANP-mediated antagonism of the renin-angiotensin system is essential for blood pressure constancy, suggesting that a deficiency in ANP activity may underlie the etiol...

The kidney has a high energy demand and is dependent on oxidative metabolism for ATP production. Accordingly, the kidney is rich in mitochondria, and mitochondrial dysfunction is a common denominator for several renal diseases. While the mitochondrial master regulator peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) is highly expressed in kidney, its role in renal physiology...

The deferred recognition of COVID-induced losses at banks in many countries has reignited the debate on regulatory forbearance. This paper presents a model where public's own political pressure drives policy astray, because public is poorly informed. Using probabilistic game stages, parameterizes how time consistent is. interaction between motivations and consistency novel complex: increased cr...

The object of research: expander the excess gas pressure utilization plant.
 Investigated problem: Increasing efficiency process during its distribution from main high-pressure pipelines. Development hardware and software tools that provide automation regulating flow parameters under influence time-varying disturbances.
 scientific results: A mathematical model has been developed, an ...
