"A most exquisite fellow" — William White and an Atlantic world perspective on the seventeenth-century chymical furnace

The seventeenth-century technologist and colonist William White (ca. 1600–73) has been cited as an alchemical tutor to Gabriel Plattes and George Starkey, and hailed as an early modern “wizard of industrial efficiency.” This study — the first that focuses on White individually — pays particular attention to White’s extraordinary reputation for furnace design and manufacture. By examining the sources of knowledge and social connections that enabled White to acquire and disseminate his knowledge of metallurgy, the authors develop a genealogy of fornacic design that extends from the continent to the Atlantic world and back again, connecting White to better known figures such as Cornelis Drebbel and Robert Boyle. By foregrounding, through White, the technology of early modern alchemy, the authors also hope to emphasise the importance of practical craft in the development of the chemical arts

Semiconductor optical amplifiers in avionics

RSOAs have been demonstrated to operate within a WDM PON architectures over a >;60nm wavelength range with large path loss capabilities. Two RSOAs enable contiguous operation over the S, C and L bands; results indicate clearly that WDM architectures suitable for avionics with a PLC of >;25dB are possible with only two devices. Performance at extended temperature ranges will be reported later in detai

Control of Variable Watermilfoil in Bashan Lake, CT with 2,4-D: Monitoring of Lake and Well Water.

Variable watermilfoil (Myriophyllum heterophyllum Michx.) has recently become a problem in Bashan Lake, East Haddam, CT, USA. By 1998, approximately 4 ha of the 110 ha lake was covered with variable watermilfoil. In 1999, the milfoil was spot treated with Aquacide®, an 18% active ingredient of the sodium salt of 2,4-D [(2,4-dichlorophenoxy) acetic acid], applied at a rate of 114 kg/ha. Aquacide® was used because labeling regarding domestic water intakes and irrigation limitations prevented the use of Navigate® or AquaKleen®, a 19% active ingredient of the butoxyethyl ester of 2,4-D. Variable watermilfoil was partially controlled in shallow protected coves but little control occurred in deeper more exposed locations. 2,4-D levels in the treatment sites were lower than desired and offsite dilution was rapid. In 2000, the United States Environmental Protection Agency (USEPA) issued a special local need (SLN) registration to allow the use of Navigate ® or AquaKleen® in lakes with potable and irrigation water intakes. Navigate® was applied at a rate of 227 kg/ha to the same areas as treated in 1999. An additional 2 ha of variable watermilfoil was treated with Navigate® in 2001, and 0.4 ha was treated in mid-September. Dilution of the 2,4-D ester formulation to untreated areas was slower than with the salt formulation. Concentrations of 2,4-D exceeded 1000 μg/ L in several lake water samples in 2000 but not 2001. Nearly all of the treated variable watermilfoil was controlled in both years. The mid-September treatment appeared as effective as the spring and early summer treatments. Testing of homeowner wells in all 3 years found no detectable levels of 2,4-D.(PDF contains 8 pages.

Identification Of A Treatment-Resistant, Ketamine-Sensitive Genetic Line In The Chick Anxiety-Depression Model

Approximately 60% of Major Depressive Disorder (MDD) patients do not respond to FDA-approved antidepressants. Introducing effective pharmacotherapies for this treatment-resistant population is hindered by the lack of pre-clinical screening assays that accurately model the clinical features of TRD. The purpose of this research was to screen representatives of different classes FDA-approved antidepressants and one novel antidepressant in two genetic lines of domestic fowl chicks that have previously been identified as stress-vulnerable and stress-resilient in the chick anxiety depression model. Separate groups of socially raised Black Australorp (stress-vulnerable) and Production Red (stress-resilient) chicks were administered the tricyclic antidepressant imipramine (0-20 mg/kg), the selective serotonin reuptake inhibitor (SSRI) fluoxetine (0-10 mg/kg), the tetracyclic antidepressant maprotiline (0-10 mg/kg), the glutamate receptor antagonist ketamine (0-15 mg/kg), or vehicle (physiological saline) and placed individually inside sound attenuating chambers for a 90-minute test period. The behavioral measure of distress vocalizations (DVocs) was recorded via custom designed software. Replication and validation of previous findings of stress sensitivity in the two genetic lines was measured by calculation of the onset of behavioral despair during the depression like phase (30-90 min). Verifying previous research, Black Australorps entered behavioral despair approximately 25% faster than Production Reds signifying the stress-vulnerability of the Black Australorp line. In the depression-like phase, Black Australorps were insensitive to imipramine and fluoxetine, but sensitive to ketamine, a finding that parallels the clinical picture of TRD. Utilization of the Black Australorps genetic line in the chick anxiety-depression model may be a novel and lone preclinical screening to identify alternative mechanisms and promising leads for TRD

A comparative study of the family recreational activities before and after television

Thesis (Ed.M.)--Boston UniversityThere have been many contrasting statements as to the helpful or destructive force television has on many families, but, because television is in its infant stages, sufficient research is lacking to produce conclusive evidence. This investigation is an attempt to discover the various forms of recreational activities in which the family participated before television and to find out whether or not the family participation in activities is less, just as much, or more after television

Australian water consumer outlook 2015

Executive Summary Do we think and talk about water only when we are in drought? Do we complain about the price of water, but are happy to pay $3 a bottle for it at the shop? Do urban residents think differently about water to people living in rural and regional areas? Do consumers know enough about our water resources to understand if governments and industry are protecting our water supply in the future? These questions and more are explored in the Australian Water Consumer Outlook. As the driest inhabited continent on earth, it’s critical we engage with and understand the attitudes of water consumers, water industry and government, and make water policy a priority. Although many utilities undertake customer satisfaction surveys they often don’t ask broader questions to gain an understanding of the consumer make-up and leadership of the industry. Further, each of these surveys is conducted independently of each other, making it difficult to identify trends and variances of perceptions nationally. The Australian Water Consumer Outlook presents the findings of the Australian Water Consumer Survey. The Survey was conducted online between 27 July and 3 September 2015 and received 3948 responses. The data gathered for the Australian Water Consumer Outlook provides a basis for further community-informed policy debate. • State based reports are also available at AWA\u27s websit
