Earthen waste lagoons are commonly used to store liquid wastes from concentrated animal feeding operations. The fate of ammonium (NH) and nitrate (NO) was studied in the vadose zone below earthen-clay dairy farm waste lagoons using three independent vadose zone monitoring systems. The vadose zone was monitored from 0.5 to 30 m below land surface through direct sampling of the sediment porewater...

baneh pluton is located in northwest of kordestan province and sanandaj-sirjan zone. this body has been injected into low-grade metamorphic rocks in cretaceous and so it is attributed to upper cretaceous-paleocene. this complex is composed of three distinct intrusive phases. these phases are diorite, biotite-granite and garnet-bearing granite. diorites is the first constituent unit that is intr...

Neurotransmitters are released by synaptic vesicle fusion at the active zone. The active zone of a synapse mediates Ca2+-triggered neurotransmitter release, and integrates presynaptic signals in regulating this release. Much is known about the structure of active zones and synaptic vesicles, but the functional relation between their components is poorly understood. Here we show that RIM1alpha, ...

An automated multi-pumping flow system was developed for the in-line generation of singlet oxygen ((1)O(2)) and subsequent assessment of the scavenging capacity against this reactive species. (1)O(2) was generated by dismutation of hydrogen peroxide catalyzed by molybdate ions. The evaluation of the scavenging capacity was based on the inhibition of the chemiluminescence reaction of luminol wit...

How can synapses change the amount of neurotransmitter released during synaptic plasticity? Although release in general is intensely investigated, its determinants during plasticity are still poorly understood. As a model for plastic strengthening of synaptic release, we here use the well-established presynaptic homeostatic compensation during interference with postsynaptic glutamate receptors ...

Fractional vortex beams (FVBs) possess unique topological properties that are manifested in the distribution. However, there still discrepancies value of strength FVBs at far field. In this work we present a complete picture behavior phase singularities non-integer (commonly known as fractional) Fraunhofer diffraction region and demonstrate very good correspondence between experiments simulatio...

Alborz Mountains is a region of active deformation within Arabia-Eurasia collision zone. The study fault system in western Alborz comprises abundant evidence of active faulting accompanied by occurrence of historical earthquakes. Active tectonics of Manjil-Rudbar fault zone whose movement caused destructive 1990 Manjil-Rudbar earthquake was concentrated in this article through geomorphic and st...

The prevalence of Indonesian smokers is increasing, the age getting younger every day, and number cigarettes consumed increasing. Smoking behavior or habits can have an impact on emergence pulmonary ventilation disorders due to irritation excessive mucus secretion in bronchi. study aimed determine correlation between age, cigarettes, duration smoking with vital capacity value lungs active smoke...
