We used remotely sensed weekly snow water equivalent (SWE) and snow cover extent (SCE) data to investigate streamflow response to seasonal snowcover change over the Yukon watershed. We quantified the seasonal cycles and variations of snowcover (both SWE and SCE) and river streamflow, and identified a clear correspondence of river discharge to seasonal snowcover change. We also examined and comp...

Hydrologic Simulation Program-Fortran (HSPF) model calibration is typically done manually due to the lack of an automated calibration tool as well as the difficulty of balancing objective functions to be considered. This paper discusses the development and demonstration of an automated calibration tool for HSPF (HSPF-SCE). HSPF-SCE was developed using the open source software “R”. The tool empl...

The zinc–manganese alloy coatings have been obtained without and with superimposition of a 0.3 T magnetic field in parallel direction to the working surface electrode. electrodeposition during 30 min, for two applied potentials (E = −1.6 V/SCE E −1.8 V/SCE) an electrochemical bath (Zn2+)/(Mn2+) concentration ratio equal 0.5. structural, morphological, chemical composition characteristics deposi...

One of the most important and valuable goal of software development life cycle is software cost estimation or SCE. During the recent years, SCE has attracted the attention of researchers due to huge amount of software project requests. There have been proposed so many models using heuristic and meta-heuristic algorithms to do machine learning process for SCE. COCOMO81 is one of the most popular...

Investigations of genotoxic effects of particles have almost exclusively been performed by organic extraction, while direct investigations in cells capable of engulfing particles have only been performed in few cases. Thus, in most studies, the eventual effects of particle-associated metal compounds have remained undiscovered. The present study attempted direct measurement of genotoxic effects ...

Cannabis is a potential treatment for epilepsy, although the few human studies supporting this use have proved inconclusive. Previously, we showed that a standardized cannabis extract (SCE), isolated Delta9-tetrahydrocannabinol (Delta9-THC), and even Delta9-THC-free SCE inhibited muscarinic agonist-induced epileptiform bursting in rat olfactory cortical brain slices, acting via CB1 receptors. T...

The sister chromatid exchange (SCE) test is a widely used method to detect chemically induced genetic damage. This method has been applied in some aquatic species to monitor genetic pollutants in estuarine and marine environments. Dose response to 5-bromodeoxyuridine (BrdU) was investigated in the mussel Mytilus gallopror~incialis Lmk. Experimental assays were carried out by incorporating 4 , 1...

Sister chromatid exchange (SCE) frequency is widely used as an indicator of spontaneous chromosome instability. We investigated SCE frequency in the peripheral blood lymphocytes of familial and sporadic breast cancer (BC) patients from the Apulian Caucasian Population. Eighty-one patients were enrolled: 22 with familial history and 59 sporadic patients. Eleven familial patients had an 'increase...

BACKGROUND The analysis of sister chromatid exchange (SCE) is a cytogenetic technique used to show DNA damage due to an exchange of DNA fragments between sister chromatids. OBJECTIVE To determine whether HLA-B27 positive patients with ankylosing spondylitis (AS) were associated with higher SCE frequencies than patients without B27. METHODS Lymphocytes from 38 patients with AS (15 women, 23 ...

When Bloom syndrome (BS) cells labeled with bromodeoxyuridine (BrdUrd) for one round of DNA replication were fused with nonlabeled normal cells, the hybrid cells had a normal level of sister chromatid exchange (SCE) at the first mitosis after fusion. However, when normal cells treated with mitomycin C (MC) were fused with nontreated normal cells, the MC-induced SCE was not affected by fusion wi...
