Concerning the theory of LURR based deterministic earthquake prediction

This paper considers theoretical aspects of a trigger effect of earth tides on earthquake initiation under the LURR approach. The growth of Coulomb stress, which appears resulting from this phenomenon, is shown to occur not for all regimes of stress state acting in the studied region. Its greatest increase corresponds to the regime of the horizontal extension and shear associated with the faults with kinematics of the normal and strike-slip faults. The low level of additional Coulomb stress for the horizontal compression regime allows asserting the low probability of the trigger effect for the faults with kinematics of the reverse faults. It is noted, that there is also an indirect factor in the form of additional pressure caused by the sea tides in addition to the main factor of the earth tides effect on deformations in the solid earth for island arcs and coastal areas of the continental crust. This is an additional vertical pressure for the ocean floor, and a lateral pressure for the crust of island arcs and coastal areas of the continents. Indirect factors significantly complicate the effect of earth tides on the Earth’s crust, completely neutralizing the influence of the direct factor in some cases.

Pheochromocytoma induced cardiomyopathy in a young man: a case report

ABSTRACT Pheochromocytoma is a tumor arising from the adrenal medulla, most frequent benign and, due to the excretion of catecholamines, a rare cause of hypertension. The diagnosis of pheochromocytoma can be challenging because of its episodic nature, unspecific symptoms and rarity. Consequently, treatment can be delayed with serious consequences for the patient. We present a case report regarding a young man with episodes of severe hypertension over a period of at least 9 years. Ultimately, with a possible trigger effect from the intake of multiple energy drinks, the patient presented with severe hypertension, symptoms mimicking acute coronary syndrome, abnormal laboratory parameters and echocardiography suggestive of severe cardiomyopathy. The patient’s pheochromocytoma was incidentally identified in a computed tomography scan during the initial workup. Although a rare condition, pheochromocytoma should be considered as a differential diagnosis, especially in young patients presenting with unexplained hypertension, chest pain and cardiac dysfunction.

Creation of Transformation Process of Polymer Films Based on Trigger Effect from the Free Surface

While we might not want to admit how much time during our day is spent looking at screens and displays, it is clear that this technology has vastly improved since televisions and monitors first came into existence. Because of these advances not only have the devices providing our entertainment rapidly improved but displays used in the workplace have made life easier in many industries. At the heart of this technology is a material that exists in a grey area between two states of matter - liquid crystals. As their name suggests liquid crystals exhibit properties of both liquids and crystals. For example, liquid crystals can flow like liquids but their molecules can be oriented in a characteristic crystal-like way. Dr Takahiro Seki, based at the Nagoya University in Japan, is an expert in this field and is leading a team that is researching how the use of liquid crystals in electronic displays can be expanded as well as greatly improved.

Study of periodic processes of changing the number of innovations in relation to Kondratiev cycles

In this paper, we propose a Supplement to the theory of the emergence of innovations in long Kondratiev cycles. The regularities of the emergence of crisis phenomena and the contribution of J. Schumpeter to the development of the innovative economy are considered. A comparative analysis of Marketing strategies is carried out. Schumpeter and N. D. Kondratiev, identified distinctive factors and common combinations. The stages of long wave cycles over several decades are analyzed. The analysis revealed innovative peaks that occur in the middle of the depression phase, followed by stages of economic activity growth after a certain period of time. The authors studied the theory of the trigger effect of depression, similar to the trigger action, which results in an avalanche of innovation growth. To confirm the theory of the existence of the “trigger effect of depression”, statistical data on the number of patents and applications filed in Russia and the United States for several decades, which are indicators of innovation activity, are presented. The authors put forward a hypothesis about the possibility of describing the periodic change in the number of innovations over time using “parametric resonance” models and the Mathieu equation.

Research of the trigger effect in diode-thyristor circuits of contactless relay devices

The paper investigates the main properties of the trigger effect in diode-thyristor circuits and proposes the creation of small-sized thyristor contactless voltage relays, combining in one device a sensitive system to changes in input voltage and powerful actuators capable of switching large load currents. The article also discusses a non-contact thyristor relay of alternating current voltage, the load mode of which is analyzed, taking into account the voltage of the transition to the open state of the thyristor and the formula for the effective value of the voltage across the load. It is proposed to use the developed such relays as contactless switching and control equipment, which allow to reliably and quickly control the operating modes of electrical equipment, regulate the reactive power of capacitor banks, create ring networks, improve the quality of electricity in distribution networks and reduce capital costs for the construction of a power supply system.

INFLUENCE OF THE ß SOLAR WIND PARAMETER ON STATISTICAL CHARACTERISTICS OF THE Ap INDEX IN THE SOLAR ACTIVITY CYCLE

We have studied the effect of the β solar wind parameter (equal to the ratio of the plasma pressure to the magnetic pressure) on statistical characteristics of the Ap index reflecting the triggering behavior of the activity of Earth’s magnetosphere. The trigger effect of the dynamics of magnetospheric activity consists in the abrupt transition from the periodic mode to the chaotic mode in the solar activity cycle. It is shown that cumulative amplitude distribution functions and power spectra of the Ap index of both the periodic and chaotic modes are well approximated by power and exponential functions respectively. At the same time, the indices of power functions and the indices characterizing the slope of the Ap index spectrum differ significantly in magnitude for the periodic and chaotic modes. We have found that Ap nonlinearly depends on β for both the modes of magnetospheric dynamics. The maximum of the Ap index amplitude for periodic modes is observed when β>1; and for chaotic ones, when β<1. In almost every cycle of solar activity, the energy of the Ap index fluctuations of chaotic modes is higher than that of periodic ones. The results indicate intermittency and its associated turbulence of magnetospheric activity. The exponential character of the spectral density of the Ap index suggests that the behavior of magnetospheric activity is determined by its internal dynamics, which can be described by a finite number of deterministic equations. The trigger effect of magnetospheric activity is assumed to be due to the angle of inclination of the axis of the solar magnetic dipole to the ecliptic plane, on which the dynamics of the β parameter in the solar activity cycle depends.
