Objective. It is generally accepted that crackles are due to sudden opening of airways and that larger airways produce crackles of lower pitch than smaller airways do. As larger airways are likely to open earlier in inspiration than smaller airways and the reverse is likely to be true in expiration, we studied crackle pitch as a function of crackle timing in inspiration and expiration. Our goal was to see if the measurement of crackle pitch was consistent with this theory.Methods. Patients with a significant number of crackles were examined using a multichannel lung sound analyzer. These patients included 34 with pneumonia, 38 with heart failure, and 28 with interstitial fibrosis.Results. Crackle pitch progressively increased during inspirations in 79% of all patients. In these patients crackle pitch increased by approximately 40 Hz from the early to midinspiration and by another 40 Hz from mid to late-inspiration. In 10% of patients, crackle pitch did not change and in 11% of patients crackle pitch decreased. During expiration crackle pitch progressively decreased in 72% of patients and did not change in 28% of patients.Conclusion. In the majority of patients, we observed progressive crackle pitch increase during inspiration and decrease during expiration. Increased crackle pitch at larger lung volumes is likely a result of recruitment of smaller diameter airways. An alternate explanation is that crackle pitch may be influenced by airway tension that increases at greater lung volume. In any case improved understanding of the mechanism of production of these common lung sounds may help improve our understanding of pathophysiology of these disorders.

Propionibacterium acnes (Cutibacterium acnes) is an anaerobic, gram-positive, slow growing bacteria. It can produce various virulence factors like bioactive exocellular products and metabolites. P.acnes blood isolates were considered signicant if two or more separate blood culture sets were positive on the same day and if systemic inammatory response syndrome (SIRS) was present without any alternate explanation. C.acnes if found in the blood of patients with implantable cardiac devices it should be considered as more than just a skin contaminant. These patients should be treated with appropriate therapies to prevent annihilatory consequences.

Timing the arrival of optical pulses from NP 0532 is a potentially important tool for studying the physics of this fascinating object. However, there are some difficulties in interpreting the data in terms of physical models. Some progress has been made on understanding the largest effect – the pulsar braking mechanism. The glitch of late September, 1969 can be interpreted as the speed-up, and subsequent relaxation, of the rotation of a neutron star crust. An alternate explanation is that of a planet in an eccentric orbit. Both models fit the rather meager data near the event. A small sinusoidal effect is indicated in a relatively quiet period of the data.

Purpose – The study aimed to investigate the information disclosure behavior of women bloggers who suffer from infertility by examining their self-disclosure as it relates to the anonymity patterns they adopted. Design/methodology/approach – A survey was distributed to approximately 300 authors of infertility blogs, 135 bloggers answered the request to take part in the study. The survey gathered basic demographic and blogging practice data, and measured different elements of the bloggers' discursive and visual anonymity as well as their patters of self-disclosure. Findings – Findings reveal that the majority of respondents identify themselves on their blogs and only a small percentage decided to be totally anonymous, and about half of the bloggers post actual photos of themselves and their lives. The participants reported a high rate of self-disclosure, revealing sensitive information, letting their defenses down, disclosing highly intimate details about their lives, writing openly about their infertility treatments on their blog. No significant correlation was observed between visual and discursive anonymity and the perceived self-disclosure of participants. Results show that the more anonymous the bloggers are, the more afraid they become that their blog may be read by people they know offline. On the other hand, the more identifiable the bloggers are, the more willingness they show to share the content of their journal with people they know offline. The majority of participants expressed concerns that blogging could negatively impact their lives. Originality/value – This study explores an alternate explanation through the examination of the bloggers' self-disclosure patterns as they relate to the degree of anonymity adopted.

The minerals of chondritic meteorites, particularly C2 and C3 are usually believed to be condensates of the (previously unfractionated) solar nebula. This implies two postulates: (1) that chemical reactions between phases ceased at various temperatures; (2) that Ni and Fe were mobilized by diffusion in the solid state. An alternate explanation is proposed, which obviates the two postulates: chondritic minerals may have condensed, in equilibrium with their own vapors, from a fraction already separated from the solar nebula at low temperature and low pressure.
