This paper describes a large cyclonic gyre that lasted several days in the northwest Pacific during July 1988. Cyclonic winds at 850 hPa extended beyond the 2000-km radius with a radius of maximum winds of 700– 800 km. The gyre exhibited clear skies within and north of its center. Active convection extended 4000 km in longitude to its south. The Madden–Julian oscillation (MJO) was in its active...

Recent evidence has supported the notion that the hypothalamic-pituitary-adrenal (HPA) and the sympatho-adreno-medullary (SAM) systems are modulated by cortical structures such as the prefrontal cortex. This top-down modulation may play a major role in the neuroendocrine changes associated with stressful events. We aimed to investigate further this hypothesis by modulating directly prefrontal c...

OBJECTIVE To evaluate the association between objective short sleep duration in patients with insomnia and changes in blood parameters related to hypothalamic-pituitary-adrenal (HPA) axis activity. METHOD A cross-sectional pilot study was conducted in 30 middle-aged adults with chronic insomnia who were divided into 2 groups according to polysomnography (PSG) total sleep time (TST) (TST > 5h ...

In s coordinates, a variable f e(x, y, s, t) whose horizontal gradient 2=f e is equal to the irrotational part of the horizontal pressure gradient force is referred to as an equivalent isobaric geopotential height. Its inner part can be derived from the solution of a Poisson equation with zero Dirichlet boundary value. Because 2=f (x, y, p, t) is also the irrotational part of the horizontal pre...

the aim of this research is the assessment of the relation between rainfall and large scale synoptically patterns at khorasan razavi province. in this study, using adaptive neuro fuzzy inference system, the rainfall estimation has been done from april to june in the area under study. spring rainfall data including the information of 38 synoptic, climatologic and rain gauge stations from 1970 to...

In this investigation, 25 adult New Zealand White rabbits randomly selected from both sexes and studied.Coloured latex injection and corrosion cast methods were applied on the materials. This study was carried out to disclose the distribution of the cardiac veins of the New Zealand White rabbits. The veins that drain the heart were found to be the great cardiac vein, the middle cardiac vein, th...

OBJECTIVE The hypothalamic-pituitary-adrenal (HPA)-axis is the most important neuro-endocrine stress response system of our body which is of critical importance for survival. Disturbances in HPA-axis activity have been associated with adverse metabolic and cognitive changes. Humans enriched for longevity have less metabolic and cognitive disturbances and therefore diminished activity of the HPA...

Dust weather is common and disastrous at the Tibetan Plateau. This study selected a typical case of dust analyzed its main development mechanism in northeast Plateau, then applied six machine learning methods time series regression model to predict PM10 concentration this area. The results showed that: (1) 24-h pressure change was positive when front intruded on surface; convergence vector wind...

FY-4A GIIRS temperature profile products have provided unprecedented information for studying the atmospheric characteristics of thermal structures since 2020. The main objective this paper is to evaluate by using radiosonde observations and then apply them diagnosis winter precipitation types in southern China. four (clear sky perfect quality, cloudy good quality bad quality) show different pe...
