efficacy of many herbicides to control broad- and narrow-leaf weeds (grass weeds) in tobacco fields of mazandaran and guilan provinces was investigated. the experiment was randomized complete blocks design in four replications and the following treatments: eptam (eradicane 82% ec) at 6 l.ha-1 which incorporated pre-planting (ppi), trifluralin (treflan 48% ec) at 2 l/ha ppi, cycloate (roneet 72....
A brief review of the theory contributions presented in the EC-18 Workshop is given. The covered spectrum of topics is quite broad including the electron cyclotron wave propagation physics as well the results of numerical modelling of transport and current drive.
I survey the parameter space of NAHE-based free fermionic heterotic string models. First, I discuss flat directions of the low energy effective field theories and show that D-flat directions need not be isomorphic to gauge invariant superpotential terms. Next, I review recent studies of three generation SU(3)C × SU(2)L × U(1)Y , SU(3)C ×SU(2)L ×SU(2)R ×U(1)B−L, SU(4)C × SU(2)L ×U(1)Y ′ , and fl...
WINNING ABSTRACT: Tobacco smoke contains a high concentration of oxidants and is the primary cause of chronic obstructive pulmonary disease (COPD). Extracellular superoxide dismutase (EC-SOD) is the major antioxidant enzyme in the extracellular space of the lung and is part of the lung defense against these oxidants. We hypothesized that EC-SOD is a risk factor for COPD. We found that EC-SOD pl...
The elemental carbon (EC)-tracer method was applied to PM10 and PM1 data of three sampling sites in the City of Berlin from February to October 2010. The sites were characterized by differing exposure to traffic and vegetation. The aim was to determine the secondary organic carbon (SOC) concentration and to describe the parameters influencing the application of the EC-tracer method. The evaluat...
©FFPRHC J Fam Plann Reprod Health Care 2007: 33(3) Background In this Commentary we review recent research about the mechanism of action of levonorgestrel emergency contraceptive pills (ECPs) and the population impact of emergency contraception (EC), and we examine the downside of making ECPs available directly from a pharmacist or other non-specialist provider without a prescription. We argue ...
BACKGROUND HER-2/neu overexpression appears to be associated with improved response to anthracycline-based chemotherapy, but its association with response to taxane-based chemotherapy is unclear. In this retrospective subset analysis of patients with metastatic breast cancer enrolled in a randomized treatment trial, we investigated the response of patients with known HER-2/neu status to treatme...
BACKGROUND AND PURPOSE Subarachnoid hemorrhage (SAH) increases production of vascular extracellular superoxide anion (*O2-). We examined whether overexpression of murine extracellular superoxide dismutase (EC-SOD) alters SAH-induced cerebral vasospasm, oxidative stress, and neurological outcome. METHODS Mice exhibiting a 2-fold increase in vascular EC-SOD and wild-type (WT) littermates were s...
