Abstract Intermittent streams are globally distributed, comprise over half the length of global river network, and expected to become more prevalent. However, most studies intermittent conducted at extremes scale, limited in taxonomic temporal scope, focus exclusively on drying patterns. Here, we assessed how both flow intermittency orientation perennial refuges affect aquatic invertebrates sem...

We analyzed intermittency in the solar wind, as observed on the ecliptic plane, looking at magnetic field and velocity fluctuations between 0.3 and 1 AU, for both fast and slow wind and for compressive and directional fluctuations. Our analysis focused on the property that probability distribution functions of a fluctuating field affected by intermittency become more and more peaked at smaller ...

Introduction An 80-year-old man with a previous history of recurrent urinary tract infections presented with intermittent, painful and whole stream gross haematuria for 2 months. Physical examination was unrevealing. The result of urine cytology was negative for malignancy. Intravenous pyelography (IVP) revealed left hydronephrosis with obstruction at left ureterovesical junction, radiolucent f...

Pc3 geomagnetic ®eld ̄uctuations detected at low latitude (L'Aquila, Italy) during the passage of a high velocity solar wind stream, characterized by variable interplanetary magnetic ®eld conditions, are analyzed. Higher frequency resonant ̄uctuations and lower frequency phenomena are simultaneously observed; the intermittent appearance and the variable frequency of the longer period modes can ...

introduction mild intermittent asthma is common in children and viral infections are responsible for the majority of exacerbations. as leukotrienes are potent inflammatory mediators, some studies have shown that montelukast, a leukotriene receptor antagonist, may be effective on reduction of asthma symptom. to determine whether a short course of montelukast in asthmatic children with common col...

Abstract. Intermittent streams represent a substantial part of the total stream network, and their occurrence is expected to increase due climate change. Thus, it high relevance provide detailed information on temporal spatial controls streamflow intermittency support management decisions. This study presents an event-based analysis responses in intermittent mesoscale catchment with temperate c...

Longer, drier summers projected for arid and semi-arid regions of western North America under climate change are likely to have enormous consequences for water resources and river-dependent ecosystems. Many climate change scenarios for this region involve decreases in mean annual streamflow, latesummer precipitation and late-summer streamflow in the coming decades. Intermittent streams are alre...

the production of experimentally induced drug resistance in the laboratory provides valuable opportunities for investigators to study the nature and genetics of drug resistance mechanisms to a given agent, patterns of cross resistance and the mode of action of drugs. at the beginning the continuous drug exposure was chosen as a standard procedure to produce drug— resistant strains of p. falcipa...

From 1994 to 1998 we documented sediment transport dynamics and sources in a 137 ha grazed hardwood rangeland watershed on granitic soils at the San Joaquin Experimental Range in Madera County. Sediment transport for this watershed was determined by measuring total suspended solids, bedload and flow at an H-flume installed in 1994. Sediment movement as bedload is the primary means of sediment t...

while fasting has been practiced for centuries, its beneficial effects was unknown until recently. this review tries to analyze the current literature of how fasting and intermittent fasting (if) could affect clinical pathological parameters, learning, mood and brain plasticity. the effects of different ways of fasting on metabolism and stress were also explored. animal experiments have elucida...
