Pages 179 i have carried this useful book in my pocket and used it with benefit in clinical meetings. It is intended for hospital doctors as a guide to practical management of people with diabetes and endocrine disorders. It describes each gland, the normal function and its variants, the symptoms and signs, the tests which might be used to establish the diagnosis and treatment. There is a sensi...

AIM The objective was to determine clinical and microbiological effects and perceived treatment discomfort of root debridement by subgingival air polishing compared with ultrasonic instrumentation during supportive periodontal therapy (SPT). MATERIAL AND METHODS The trial was conducted as a split-mouth designed study of 2-month duration including 20 recall patients previously treated for chro...

N(5)-Carboxyaminoimidazole ribonucleotide synthetase (N(5)-CAIR synthetase), a key enzyme in microbial de novo purine biosynthesis, catalyzes the conversion of aminoimidazole ribonucleotide (AIR) to N(5)-CAIR. To date, this enzyme has been observed only in microorganisms, and thus, it represents an ideal target for antimicrobial drug development. Here we report the cloning, crystallization, and...

The cohesion-tension theory expounds the crude sap ascent thanks to the negative pressure generated by evaporation of water from leaves. Nevertheless, trees pose multiple challenges and seem to live in unphysical conditions: the negative pressure increases cavitation; it is possible to obtain a water equilibrium between connected parts where one is at a positive pressure and the other one is at...

We describe Conoco’s closed-loop approach to reducing undesirable emissions through vapor recovery at some of its natural gas production facilities near Corpus Christi, Texas. In response to the U.S. Clean Air Act Amendments of 1990 (CAAA), Conoco developed a technological solution that routed emissions from the facilities to fuel scrubbers and condensers to capture usable product and hazardous...

The standard observatory procedure for determining a geomagnetic field’s declination and inclination absolutely is the DI-flux measurement. The instrument consists of a non-magnetic theodolite equipped with a single-axis fluxgate magnetometer. Additionally, a scalar magnetometer is needed to provide all three components of the field. Using only 12 measurement steps, all systematic errors can be...
