virtual water adds a new dimension to crop trades and provides a new way of thinking about water scarcity. a systematic analysis of virtual water flows requires integration of all critical drivers of virtual water flows under a single consistent framework. the aim of this study was to assess virtual water flows related to trades of grain crops (wheat, corn, rice, and coarse cereals) and their i...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
BACKGROUND Dementia is a major public health problem, and repeated cognitive data from large epidemiological studies could help to develop efficient measures of early prevention. Data collection by self-administered online tools could drastically reduce the logistical and financial burden of such large-scale investigations. In this context, it is important to obtain data concerning the comparab...
lead is quantitatively retained on 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-br-padap)-ammonium tetraphenylborate with microcrystalline naphthalene or by a column method in the ph range 4.0-6.0 from a large volume of aqueous solutions of various samples with preconcentration factor of 60. after filtration, the solid mass consisting of the lead complex and naphthalene was dissolved with 5...
conclusions anesthetic management for ire of soft tissue deviates from standard anesthetic medical therapy in regards to depth of neuromuscular blockade and analgesic management during ire energy delivery. however, minor modifications in anesthesia management allow for a safe and efficient patient procedure. results during ire delivery, a deeper neuromuscular blockade is required to ensure that...
the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...
Vanadium is quantitatively retained on 2-nitroso-1-naphhthol-4-sulfonic acid tetradecyldimethlbenzyammonium chloride onto microcrystalline naphthalene in the pH range of 3.0-4.0 from a large volume of aqueous solutions of various alloys and synthetic samples. After filtration, the solid mass consisting of the vanadium complex and naphthalene was dissolved with 5.0 mL of dimethylformamide an...
abstract background: adjacent treatment fields are commonly used in external beam radiation therapy, such as mantle and inverted-y fields for the treatment of hodgkin’s disease and craniospinal fields used in the treatment of medulloblastoma and head and neck tumors when the lateral neck fields are placed adjacent to the anterior supraclavicular field. in each of these situations, there is a po...
