Bios is a new type of organization characterized by the continual generation of novel patterns. Bios thus provides a new concept regarding physiological regulation and creative evolution. Different types of biotic patterns have been found in physiological and economic time series, and can be generated by the process equation A(t+1) = A(t)+ g t sin(A(t)) that models the diversity of positive and...

Along with productivity and physiology, morphological growth behavior is the key parameter in bioprocess design for filamentous fungi. Lacking tools for fast, reliable and efficient analysis however, fungal morphology is still commonly tackled by empirical trial-and-error techniques during strain selection and process development procedures. Bridging the gap, this work presents a comprehensive ...

The sleep onset process (SOP) is a dynamic process correlated with a multitude of behavioral and physiological markers. A principled analysis of the SOP can serve as a foundation for answering questions of fundamental importance in basic neuroscience and sleep medicine. Unfortunately, current methods for analyzing the SOP fail to account for the overwhelming evidence that the wake/sleep transit...

abstract background: most of the patients admitted in the intensive care units (icus) require an endotracheal tube and mechanical ventilation. in order to clear and maintain patency of the airways, endotracheal suctioning is required. therefore, the least detrimental way of endotracheal tube suctioning which can diminish the complications should be selected. the present study aimed to compare t...

introduction preterm infants are exposed to irregular light for several weeks or months in the neonatal intensive-care unit (nicu). this lack of maternal entrainment, the exposure to irregular extrauterine lighting and care in the nursery may contribute to the disturbances in body temperature, sleep and physiological changes that are commonly experienced by preterm infants. materials and method...

background & aim: cassia angustifolia vahl is a valuable medicinal plant that it is important for constipation treatment. according to the importance of organic agriculture in increasing the yield of medicinal plants, the effect of bio-fertilizer on quantities yields of cassia angustifolia vahl or senna in karaj region (iran) was examined. experimental: this research was carried out in rand...

angiogenesis or formation of new blood vessels from preexisting vasculature is a key process in some physiological conditions such as wound healing, growth, and action of female reproductive organs. moreover, disturbance of the mechanisms of physiological angiogenesis has a role in pathogenesis of some diseases in the form of overproliferation of blood vessels such as cancers, psoriasis, arthri...

heat stress effects on physical and mental health of workers and decreases human function. asphalt workers are both exposed to the heat of their working process and to the sun heat. this study aimed at evaluating thermal stress and its following function fall and the effect of asphalt work on the degree of heat stress and asphalt workers’ physiological parameters. the present study was done at ...

During the course of pregnancy numerous and important physiological changes occur in the maternal organism. These changes are most peculiar, and rarely follow any definite order sometimes they appear almost immediately after conception, at other times they do not develop until the later months. The phenomena commonly associated with the state of pregnancy may be called physiological, and it is ...
