introduction: diabetes is the most common disease related to metabolism disorders with long term complications. it needs lifelong specific self-care, as it causes a promotion in quality of life and decreases disease costs. the health belief model (hbm) is a psychological model that attempts to explain and predict health behaviors. this is done by focusing on the attitudes and beliefs of individ...

Researchers of spectral-amplitude coding optical CDMA (SAC-OCDMA) have often suggested that code patterns affect signal-to-noise ratio (SNR) of the system. However, research that as the link between fibre nonlinearity and its impact on SAC pluses evolution is scant. Therefore, the aim of this paper attempts to explore how the deployment of nonlinearity compensation improves the system property....

1. Isolation of a self-emptying sac of rat small intestine in vivo halved the cell production rate in the crypts of Lieberkühn as measured by colchicine blockade. 2. Starvation for 48 h of rats with isolated intestinal sacs caused a further halving of cell production rate in the sac. 3. Infusion of distilled water into isolated intestinal sacs for 72 h caused a similar degree of stimulation of ...

This study investigated effects of microalgae (Rhodomonas baltica) and heterotrophic protists (Oxyrrhis marina) on the daily growth, activity, condition and feeding success of Atlantic herring (Clupea harengus) larvae from hatch, through the end of the endogenous (yolk sac) period. Yolk sac larvae were reared in the presence and absence of microplankton and, each day, groups of larvae were prov...

In this paper, a motion planning method based on the Soft Actor-Critic (SAC) is designed for dual-arm robot with two 7-Degree-of-Freedom (7-DOF) arms so that can effectively avoid self-collision and at same time joint limits singularities of arm. The left-arm right-arm each have neural network to control its position orientation. Dual-agent training, distributed training structure, progressive ...

In flowering plants, pollen grains germinate to form pollen tubes that transport male gametes (sperm cells) to the egg cell in the embryo sac during sexual reproduction. Pollen tube biology is complex, presenting parallels with axon guidance and moving cell systems in animals. Pollen tube cells elongate on an active extracellular matrix in the style, ultimately guided by stylar and embryo sac s...

purpose: to describe the prophylactic patterns for endophthalmitis after cataract surgery in iran. methods: in this cross-sectional study, 486 ophthalmologists, members of iranian society of ophthalmology, who participated in the 20th annual meeting of ophthalmology in december 2010, tehran-iran, filled a self-administered questionnaire. a wide range of ophthalmologists, from all around the cou...
