Abstract

Mahoney Lake is a small, meromictic saline lake in south-central British Columbia noted for its unique layer of purple sulfur bacteria. First examined in 1969, this lake has undergone physical, chemical, biological, and pre-historical research to generate an understanding of how the lake and its biota function have developed through time. Advances in understanding the sulfur transformations and bacterial nutrient cycling over the last fifty years have been prolific, resulting in the description of several new taxa. Mahoney Lake is exceptional in its limnological characteristics and is an ideal site for training future limnologists.

20. EVALUATING DIGITAL VALVE CONTROLLER OPTIONS.

Author

VALVES
Abstract

Digital valve controllers have evolved significantly over the past 30 years, offering improved performance, diagnostics, and repair advice. The introduction of electro-pneumatic positioners in the 1970s addressed the issue of control valves not reaching and holding the desired position due to various factors. These positioners evolved into digital valve controllers with the incorporation of microprocessors, better sensors, and diagnostics. The latest generation of digital valve controllers offers features such as multilingual capabilities, easy configuration, advanced sensing, data storage, data analytics, universal application, and upgradeability. These controllers play a critical role in automated control, improving valve monitoring and troubleshooting, and reducing unplanned outages. When choosing digital valve controllers, end users should consider the specific features offered to take advantage of significant improvements. [Extracted from the article]

31. Spanish/Espanol. Resource Guides for Teachers.

Author

Centre for Information on Language Teaching and Research, London (England)., Hall, Ken, and Clayton, John

Abstract

This resource guide is designed for teachers and others interested in fostering Spanish instruction in the schools of the United Kingdom, especially at the secondary level. The first of nine chapters looks at the status of and rationale for Spanish language instruction in the United Kingdom. The second chapter addresses topics in instructional management, including identification of learner needs, using available resources, and evaluating instructional materials. Filling in the gaps in instructional materials by creating or adapting existing materials is the subject of chapter 3. Chapter 4 offers ideas for incorporating Spanish culture into the classroom environment, and chapter 5 offers guidelines for the teacher in the arrangement of visits and travel. The sixth and seventh chapters focus on the objectives of student assessment and on standardized tests. Finally, chapters 8 and 9 provide, respectively: guidelines for helping students who want to pursue higher level courses in Spanish or to use it in jobs and careers; and information on courses, conferences, and other resources for the future professional development of the teacher. A glossary and list of useful addresses are appended. (MSE)

Abstract

Clinton Derricks, actor and singer, collects golliwogs, the black figures made popular in storybooks more than 100 years ago in Britain. A group of three golliwogs that are particularly prized for their uniqueness are a soldier golliwog dressed in British khaki uniform, a girl golliwog that was quite rare as not many of the dolls were depicted as girls, and a third doll, with blue jacket, red trousers and red bow tie.

46. Purple sulfur bacteria control the growth of aerobic heterotrophic bacterioplankton in a meromictic salt lake

Author

Subjects

Abstract

The purple sulfur bacterium, Amoebobacter purpureus, is the main source of phosphorous for the chemoheterotrophic bacterioplankton development in the mixolimnion of the meromictic Mahoney salt lake, Canada. The amount of chlorophyll a and the primary production of the phytoplankton is unrelated to the growth rates of bacteria. Inorganic phosphorous or nitrogen controls the bacterial growth rates, but the appearance of the sulfur bacteria cells increases the biomass of the heterotrophic bacteria.
