The expanding science of circadian rhythm biology and a growing literature in human clinical research on circadian rhythm sleep disorders (CRSDs) prompted the American Academy of Sleep Medicine (AASM) to convene a task force of experts to write a review of this important topic. Due to the extensive nature of the disorders covered, the review was written in two sections. The ...

Two basic questions in bioprocess modeling are how many rate equations must be specified and which processes (substrate uptake, product formation, etc.) they should describe. The number of rate equations is constrained by the yield equations, which represent the balances of reducing power, energy in the form of ATP, and the various elements involved in microbial metabolism. These balances are ...

Bioprocess model structures that require nonlinear parameter estimation, thus initialization values, are often subject to poor identification performances because of the uncertainty on those initialization values. Under some conditions on the model structure, it is possible to partially circumvent this problem by an appropriate decoupling of the linear part of the model from the nonlinear part of ...

Bioconversions of lignocellulosic biomass, in particular sawdusts, into ethanol were investigated. First, acid hydrolyses by dilute sulfuric acids using 0.5, 1.0, and 2.0 weight percent were performed. The optimum hydrolysis condition was found to be 1% acid at 124C and hydrolysis time 50 min. The total yields of saccharification, primarily xylose, is 23.7 g which is obtained from 100 grams of ...

Growth of microbial and mammalian cells can be classified into substrate-limited and substrate-sufficient growth according to the relative availability of the substrate (carbon and energy source) and other nutrients. It has been observed for a number of microbial and mammalian cells that the consumption rate of substrate and energy (ATP) is generally higher under substrate-sufficient conditions ...

R. Inglehart (1990, 2005) considers values to be one's reactions to changes in the environment. According to his approach values develop in the socialisation process. Values can be divided into traditional, modernist and postmodernist. According to Rokeach (1973), values are an element of culture, an image of the desirable that might not be directly expressed in human behaviour. ...

A significant proportion of the workforce in industrialized countries (16%) are employed as shift workers. These workers may be susceptible to shift work disorder (SWD), a circadian rhythm sleep disorder, particularly those who work at night or on early-morning shifts. Shift work disorder remains an underdiagnosed and undertreated problem among this population. Patients with SWD have difficulty ...

The International Classification of Sleep Disorders (ICSD-2) has separated sleep-related movement disorders into simple, repetitive movement disorders (such as periodic limb movements in sleep [PLMS], sleep bruxism, and rhythmic movement disorder) and parasomnias (such as REM sleep behavior disorder and disorders of partial arousal, e.g., sleep walking, confusional arousals, night terrors). Many ...

A substantial portion of patients with obstructive sleep apnea (OSA) seek alternatives to positive airway pressure (PAP), the usual first-line treatment for the disorder. One option is upper airway surgery. As an adjunct to the American Academy of Sleep Medicine (AASM) Standards of Practice paper, we conducted a systematic review and meta-analysis of literature reporting ...

These practice parameters pertain to the treatment of hypersomnias of central origin.
