Abstract:

Purpose Degraded failures and sudden critical failures are quite prevalent in industries. Degradation processes commonly belong to Weibull family and critical failures are found to follow exponential distribution. Therefore, it becomes important to carry out reliability and availability analysis of such systems. From the reported literature, it is learnt that models are available for the situations where the degraded failures as well as critical failures follow exponential distribution. The purpose of this paper is to present models suitable for reliability and availability analysis of systems

Abstract:

Despite increased availability of effective drug therapy for treatment of heart failure (HF), the morbidity and mortality in chronic heart failure (CHF) are unacceptably high. Therefore, there is an urgent need to ascertain new imaging techniques to identify early sub-clinical forms of cardiac dysfunctions, to guide early relevant treatment. It seems that all the behavioral risk factors—such as tobacco, alcoholism, Western-type diet, sedentary behavior and obesity, emotional disorders, and sleep disorder are associated with early cardiac dysfunction, which may be identified by speckle-tracking

Abstract:

Neurosyphilis occurs when the nervous system is affected by the Treponema Pallidum bacterial species. Medical literature describes two clinical stages: early and late. Early can be asymptomatic or show signs of meningitis and meningoencephalitis. Conversely, late presents as parenchymal, vascular abnormalities, tabes dorsalis or syphilitic gumma. Although neurosyphilis is now uncommon, knowledge of key physical exam findings is crucial to its consideration and subsequent diagnosis and management.

Abstract:

<strong><em>Context:</em></strong><em> Heart failure (HF) is defined as a clinical syndrome that is caused by mal-structural and malfunctional changes in the myocardium resulting in an impairment of ventricular filling or the ejection fraction. There are many causes of HF such as reduced ventricular function, ischemia related malfunction, and hemodynamic overload. HF is mostly clinically diagnosed and classified, but laboratory markers help in confirming the diagnosis. <strong>Methodology:</strong> We conducted this review using a comprehensive search of MEDLINE, PubMed, and EMBASE, January 19

With the rapid growth of express delivery industry, service failure has become an increasingly pressing issue.

The cases of premature failure of the barrel of liquid damper, made of complex alloyed high-strength 30HGSN2A steel, are analyzed.

Fatigue failure of the barrels during an operation is due to the failure of the chrome coating of the rod and the appearance of scorings on the surface of the barrel. Cases of failure of the barrels during official tests are associated with the reduced hardenability and an increased tendency to decarburize steel in the bottom of the barrel, due to the increased nitrogen content here (due to seg

Abstract:

According to literature, commercial failures should not be dramatized, since they constitute potential sources of learning. Another idea advanced is that failure often acts as a stimulus to change inside an organization. Here, we suggest considering the change in a firm's behavior, after a disappointment, as the ultimate stage of learning through failure. In fact, this process is divided into two successive stages: a phase of cognitive development, followed by a behavioral development one. In this paper, we show that the impact of failure on an organization's behavior answers "garbage can" log

Abstract:

Heart failure (HF) is a progressive disease state resulting from disorders of the pericardium, myocardium, endocardium, heart valves or from certain metabolic diseases. Heart failure is the preferred term over congestive heart failure, since not every patient presents with fluid overload. Patients with heart failure will often have symptoms of left ventricular (LV) myocardium dysfunction. HF patients can have a wide range of LV functions leading to various ejection fraction (EF).

Abstract:

PurposeEntrepreneurs nurture their ambitions of founding tech start-ups that facilitate significant innovations despite vulnerability and considerable uncertainty by resolutely addressing multiple challenges to avert failures. The paper aims to answer how soon do tech start-ups fail, given their lifecycle comprising multiple stages of formation and what attributes hasten failure of tech start-ups over their lifecycle? These questions have not been answered adequately, particularly in the context of India's emerging economy, where an aspiring start-up ecosystem is striving to flourish at an exc

Abstract:

Progression of chronic obstructive pulmonary disease has a considerable effect on heart function including pulmonary hypertension, cor-pulmonale, Right and Left sided heart dysfunction. As COPD and heart failure (HF) share a common clinical feature, delay in diagnosis is associated with increased mortality. We aimed to study the incidence of heart failure in patients with COPD exacerbation.142 patients were enrolled for study. It is a cross-sectional comparative study. We categorized exacerbation into two groups: respiratory failure and non-failure group. Patients were staged by spirometry aft

Abstract:

Encountering a problem or error in the final stages of providing products or services increases costs and delays scheduling. The key task is to ensure quality and reliability in the early stages of the production process and prevent errors from occurring from the beginning. Failure mode and effect analysis (FMEA) is one of the tools for identifying potential problems and their impact on products and services. The conventional FMEA technique has been criticized extensively due to its disadvantages. In this study, the concepts of uncertainty and reliability are considered simultaneously. The pro

Abstract:

Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are cardiac hormones that are involved in water and electrolyte homeostasis in heart failure. Although both hormones exert almost identical biological actions, the differential regulation of cardiac ANP and BNP mRNA in compensated and overt heart failure is not known. To study the hypothesis that cardiac BNP is more specifically induced in overt heart failure, a large aortocaval shunt of 30 days duration was produced in rats and compared with compensated heart failure. Compensated heart failure was induced either by a small s

Abstract:

<em>After practicing the dynamic stresses from environmental change and vehicular loading, signs of failure initiation appear in asphalt concrete throughout its service life in the form of rutting, cracking, or other types of distress. In this work, an attempt has been made to detect the stages of failure initiation in asphalt concrete at the laboratory testing conditions. The role of constant strain level and asphalt binder content were assessed through a detailed testing program. Various mixtures of asphalt concrete were prepared with optimum binder content and with (± 0.5 %) asphalt

Landslides that occur near residential regions are most commonly a result of shallow slope failure, which takes place as a consequence of heavy rainfall during the monsoon season, causing loss to human life and property. In this study, the characteristics of the volumetric water content (VWC) gradient were analyzed to predict shallow slope failure which was reproduced based on flume experiments performed at various slope conditions. The VWC gradient values were calculated for each measurement position and slope depth. Moreover, the VWC gradient characteristics during the occurrence and nonoccu

Abstract:

Safety-critical systems must be shown to be acceptably safe to deploy and use in their operational environment. One of the key concerns of developing safety-critical systems is to understand how the system behaves in the presence of failures, regardless of whether that failure is triggered by the external environment or caused by internal errors. Safety assessment at the early stages of system development involves analysis of potential failures and their consequences. Increasingly, for complex systems, model-based safety assessment is becoming more widely used. In this paper we propose an appr
