background: fasciolosis is an important health and veterinary problem in iran. the epidemiological pattern of disease has been changed markedly in recent years and there are regions that have potent capacity to be new focus of the disease. one of these areas is yasuj district in southwest of iran where animal fasciolosis has been quite common. the current study was conducted to determine the s...
abstract emergence agitation that has been first described by eckenhoff et al. in 1960’s is a dissociated state of consciousness in which the child is inconsolable, irritable, uncooperative, typically thrashing, crying, moaning or incoherent. it is also a common problem in pediatric postanesthetic care unit with an incidence ranging from 10 to 80%. this literature review focused on presence of ...
Despite its current popularity, “emergence” is a concept with a venerable history and an elusive, ambiguous standing in contemporary evolutionary theory. This chapter briefly recounts the history of the term and details some of its current usages. Not only are there radically varying interpretations about how to define emergence but “reductionist” and “holistic” theorists hold very different vi...
We aimed to identify the incidence, duration and causes of delayed emergence from anesthesia in patients with dystonia undergoing surgery for deep brain stimulation (DBS) placement. A retrospective review of patients with dystonia who underwent DBS placement was conducted and the following characteristics were noted: age, gender, comorbid conditions, American Society of Anesthesiologists classi...
shoot:root ratio, dry matter partitioning, growth analysis, and water use efficiency of oat (avena sativa l., cv. walker) was investigated under excessive nitrogen (n) as 200 mg n kg-1 (n1p0), excessive phosphorus as 200 mg p kg-1 (n0p1), and combined 100 mg n+100 mg p kg-1 (n2p2), and the control (n0p0) as check in a pot experiment at dryland agriculture institute, west texas a and m universit...
The need to identifying seeds with low vigor and poor emergence led to introduce of various seed vigor tests. The purpose of this experiment was to assess the ability of controlled deterioration test for evaluation of seed vigor and prediction of oilseed rape seed lots emergence in the field. Samples of 19 seed lots were obtained from nineteen farmers of Razavi and Northern Khorasan Provinces...
prediction of weed emergence timing would help minimize crop yield loss and reducing herbicide use by optimization of the timing of weed control. therefore, seedling emergence evaluation was conducted in different irrigation levels (40, 60, 80, 100 percent of crop water requirement and furrow irrigation) to develop a thermal time seedling emergence model for amaranthus retroflexus l. in sunflow...
this study was conducted to compare the methods of seed bedpreparation in rangelands of khash region in sistan and baluchestan province iniran. a split plot design was conducted based on randomized complete blockdesign with three replications in 1999. five seed bed preparation methods wereused as main plot as: 1) seed sown by passing livestock. 2) seed sown machinery.3) seeds sown as drilled in...
Serious attention to hazardous chemical pesticides began with publication of the book “Silent Spring” by Rachel Carson in 1962. Scientists believe that agriculture had the greatest impact on the environment. The most reliable evidence comes from application of million tons of chemical fertilizers and pesticides with short or long adverse effects on ecosystem. Therefore, it is essential to imple...
this experiment was conducted to investigate the genetic diversity, relationship between morphological, agronomic and qualitative traits and to identify components of forage yield using some multivariate statistical methods in local sainfoin populations. the experiment was conducted as randomized complete block design with four replications in isfahan university of technology research farm. res...
