Bundesaußenminister Guido Westerwelle hat das Vorgehen der syrischen Armee gegen Oppositionelle verurteilt. Durch die Gewalt und den Einsatz schwerer Waffen drohe im Norden des Landes eine humanitäre Krise, erklärte er in Berlin. Westerwelle forderte die Regierung in Damaskus auf, die Angriffe auf
Zebra mussel current distribution
In the last 20 years, zebra mussels have spread from the Great Lakes to most major freshwater areas in the Eastern United States.
Online Echocardiography & Stress Test Calculators
The goal of CardioMath is to develop a comprehensive set of web-based clinical cardiology calculators to assist healthcare practitioners and students in the field of cardiology to perform day-to-day clinical calculations. For each formula, we have provided the reference values, a detailed explanation, as well as links to relevant references listed at PubMed. In addition, for the echocardiography formulas, simple and easy to understand illustrations are provided to explain where and how the measu
Next steps
Plate tectonics is an earth sciences topic that attracts a good deal of interest, given that it a topic very often featured in popular science programmes on TV and radio. It is a subject that have strong visual appeal. The coverage is S279 is self-contained, up to date and is written in a way that will be accessible to those with interest and motivation, all the more so for those who have some pre-existing scientific understanding.
Polyacrylamide Gel Electrophoresis (PAGE) of Blood Proteins
In this laboratory exercise, students utilize differential precipitation and polyacrylamide gel electrophoresis in combination with centrifugation and detergent extraction to fractionate the complex mixtures of proteins found in mammalian red blood cells and mammalian blood plasma and to characterize some of the component proteins. Gels are stained with Coomassie blue and migration distances for the unknown proteins are compared with those of known protein standards. Students then determine the
Quorum Sensing in Agrobacterium tumefaciens Using N-oxo-Acyl-homoserine Lactone Chemical Signal
Bacteria utilize a low molecular weight chemical belonging to the N-oxo-acylhomoserine lactone (HSL) family for communication by quorum sensing. In this exercise we observe HSL production in wild type Agrobacterium tumefaciens. with the aid of a reporter strain (a modified A. tumefaciens strain with a lacZ reporter gene). The reporter strain produces ?-galactosidase in response to exogenous HSL generated by the test organism. This production is first measured qualitatively by observing X-gal cle
Red Mutant Hunt with Saccharomyces cerevisiae
A laboratory exercise that links classical genetics with molecular genetics using yeast Saccharomyces cerevisiae.

Build a LabVIEW subVI to simulate an additive white Gaussian noise-impaired channel.
util_BitsToWords.vi
Build a LabVIEW subVI to convert a bitstream into a wordstream (sequence of k-bit words).
util_BitstreamFromRandom.vi
Build a LabVIEW subVI to generate a bitstream from a random number generator.
Normal - Mental Status Exam - Language Sub-exam - Patient 1
Patient is a female with no known neurological health problems who volunteered to act as a simulated patient in order to demonstrate 'normal' responses to exam techniques. She is merely a reference point for exam procedures and protocols, as well as to denote subtle signs from diagnosed patients.
Cerebellar Degeneration - Reflexes Exam - Abnormal (Pathological) Sub-exam - Patient 3
This 42-year-old man complains of poor balance and frequent falls for 6 years. Imbalance has been progressive; he cannot ambulate independently at present. He experiences tremors and weakness. Imbalance has been progressive and he now cannot ambulate independently. He is in good general health except for heavy alcohol use. For the last 10 years, he has consumed a quart of vodka and 5 beers daily. On awakening, he feels "shaky" and calms himself with a morning drink. He has not had blackouts or
Cervical Myelopathy - Reflexes Exam - Superficial Sub-exam - Patient 13
This 46-year-old African American male presented with progressive weakness of the lower extremities for three months. He had increasing difficulty with walking and balance and now is unable to walk without assistance. He also complained of numbness and "pins and needles" sensation in the upper extremities with clumsiness and decreased dexterity in his right hand. He did not have neck or radicular pain and had no bowel or bladder problems or sexual dysfunction, but did have some urinary urgency.
Cervical Myelopathy - Station and Gait Exam - Station Sub-exam - Patient 13
This 46-year-old African American male presented with progressive weakness of the lower extremities for three months. He had increasing difficulty with walking and balance and now is unable to walk without assistance. He also complained of numbness and "pins and needles" sensation in the upper extremities with clumsiness and decreased dexterity in his right hand. He did not have neck or radicular pain and had no bowel or bladder problems or sexual dysfunction, but did have some urinary urgency.
Cervical Myelopathy - Motor Exam - Screening Tests Sub-exam - Patient 13
This 46-year-old African American male presented with progressive weakness of the lower extremities for three months. He had increasing difficulty with walking and balance and now is unable to walk without assistance. He also complained of numbness and "pins and needles" sensation in the upper extremities with clumsiness and decreased dexterity in his right hand. He did not have neck or radicular pain and had no bowel or bladder problems or sexual dysfunction, but did have some urinary urgency.
Parkinson Disease - Reflexes Exam - Frontal (Release) Signs Sub-exam - Patient 10
The patient is a 68-year-old Caucasian male admitted to the VA on February 27, 2002, because of severe tremors and inability to walk due to chronic Parkinson Disease. This gentleman had been living with Parkinson Disease for many years and apparently, in spite of prescribed medications, had not improved or was getting worse. He experiences tremors, drooling, an inability to walk, and difficulty swallowing. Recently he had been unable to take the full dose of his carbidopa/levodopa medication du

A slew of international financial crises in the early 1990's, including collapses in Mexico, Southeast Asia, and Russia, highlighted the important influence international lending organizations such as the International Monetary Fund (IMF) and the World Bank had over economic decisions in the developing world. Often in cooperation with local elites, these bodies have forced countries to respond to debt crises by privatizing public industries and utilities, in many cases selling these public resou
