Introduction: Phase transformations occurring during severe meteoritic impacts on planetary bodies are crucial indicators for estimating maximum shock pressures and temperatures. Their identification is not only essential for a detailed understanding of the shock history and origin of these meteorites, but also for deciphering their pre-shock petrology and magmatic evolution. Most shock-induced...

This paper studies a geometric-process maintenance-model for a deteriorating system under a random environment. Assume that the number of random shocks, up to time , produced by the random environment forms a counting process. Whenever a random shock arrives, the system operating time is reduced. The successive reductions in the system operating time are statistically independent and identicall...

results we performed rush on 77 patients. kappa index was 0.71 (p value = 0.000), reflecting acceptable general agreement between initial impression and final diagnosis. for hypovolemic, cardiogenic and obstructive shock, the protocol had an npv above 97% yet it had a lower ppv. for shock with distributive or mixed etiology, rush showed a ppv of 100% but it had low sensitivity. subgroup analysi...

conclusions hepatic shock is detected in ill patients, especially those with hemodynamic disorders. it can be prevented by early treatment of underlying disease. there is no definite treatment for hepatic shock and should be managed conservatively. hepatic shock in patients can increase the mortality rate. results different causes can lead to hepatic shock. most of these causes can be prevented...

Abstract: This paper aims to develop a method of reliability modeling for a two-stage degraded system, facilitating the decision-making on the system maintenance. Cumulative damage model is used to present the degradation process with changing degradation rates. In the cumulative damage model, shock damage value and shock counting are assumed to be Gamma distribution and homogeneous Poisson pro...

BACKGROUND Septic shock is a leading cause of mortality in intensive care units. No new interventions in the last 20 years have made a substantial impact on the outcome of patients with septic shock. Identification of inhibitable pathways that mediate death in shock is an important goal. MATERIALS AND METHODS Two novel caspase inhibitors, (2-indolyl)-carbonyl-Ala-Asp-fluoromethylketone (IDN 1...

Background: Heat shock may affect different aspects of oocyte maturation and its subsequent development to the blastocyst stage. A series of in vitro experiments was performed to determine whether physiologically heat shock (41°C) disrupts the progression of the ovine oocytes through meiosis, activation and blastocyst formation. Materials and Methods: The cumulus-oocyte complexes (COCs) were as...

During cellular adaptation to low temperature, Escherichia coli transiently synthesizes the major cold-shock protein CspA. It was found that adaptation to cold shock is blocked when the 143-base sequence of the 5' untranslated region (5' UTR) of the cspA mRNA is overproduced. The overproduction of this UTR at 15 degrees C caused the synthesis of not only CspA but also other cold-shock proteins ...

Objective: Septic shock is a response to infection and tissue hypoperfusion which does not respond to fluid therapy and eventually leads to organ dysfunction. Aggressive treatment of a broad-spectrum antimicrobial and supportive measures are the cornerstones of successful treatment. In addition to the main treatment, there are adjunctive therapies. Steroids are one of the treat...
