Evaporative Roof Cooling - A Simple Solution to Cut Cooling Costs
No full textSince the "Energy Crisis" Evaporative Roof
Cooling Systems have gained increased acceptance
as a cost effective method to reduce the high cost
of air conditioning. Documented case histories in
retrofit installations show direct energy savings
and paybacks from twelve to thirty months.
The main operating cost of an Evaporative
Roof Cooling System is water. One thousand
gallons of water, completely evaporated, will
produce over 700 tons of cooling capability.
Water usage seldom averages over 100 gallons per
1000 ft^2 of roof area per day or 10 oz. of
water per 100 ft^2 every six minutes.
Roof Cooling Systems, when planned in new
construction, return 1-1/2 times the investment
the first year in equipment savings and operating
costs. Roof sprays are a low cost cooling
solution for warehouses, distribution centers and
light manufacturing or assembly areas with light
internal loads. See text "Flywheel Cooling.

Identification of Trichinella-Pseudospiralis from a human case using random amplified polymorphic DNA
No full textA human case of infection by Trichinella pseudospiralis has recently been described. Some morphologic anomalies of the muscle larvae, however, raise the possibility of an incorrect taxonomic attribution. A molecular taxonomic approach has therefore been applied for the identification of the parasite. Random amplified polymorphic DNAs were obtained from a single larva extracted from a muscle biopsy of the suspected case of T. pseudospiralis infection, and compared with those derived from 27 reference strains of Trichinella spp. Nearly identical amplification patterns were obtained from the suspected larva and from reference strains of T. pseudospiralis, thus supporting the original morphology-based identification. An enzyme-linked immunosorbent assay and Western blots carried out on pretreatment and post-treatment sera provided further confirmation
A first survey of the global population size and distribution of the Scottish Crossbill Loxia scotica
No full text"The survey was part-financed by Scottish Natural Heritage"A survey of Scottish Crossbills Loxia scotica was carried out in 3,506 km2 of conifer woodland in northern Scotland during January to April 2008 to provide the first estimate of the global population size for this endemic bird. Population estimates were also made for Common Crossbills L. curvirostra and Parrot Crossbills L. pytyopsittacus within this range. Crossbills were lured to systematically selected survey points for counting, sexing and recording their calls for later call-type (species) identification from sonograms. Crossbills were located at 451 of the 852 survey points, and adequate tape-recordings made at 387 of these. The Scottish Crossbill had a disjunct distribution, occurring largely within the eastern part of the study area, but also in the northwest. Common Crossbills had a mainly westerly distribution. The population size of postjuvenile Scottish Crossbills was estimated as 13,600 (95%C.I. 8,130–22,700), which will approximate to 6,800 (4,065–11,350) pairs. Common Crossbills were more abundant within this range (27,100, 95% C.I. 14,700–38,400) and Parrot Crossbills rare (about 100). The sex ratio was not significantly different from parity for Scottish Crossbills. The modal number at survey points was two but numbers were larger in January than later in the survey. The numbers and distribution of all crossbill species are likely to vary between years, depending upon the size of the cone crops of the different conifers: all were coning in 2008. Common Crossbill and Parrot Crossbill numbers will also be affected by irruptions from continental Europe. A monitoring scheme is required to detect any population trend, and further work on their habitat requirement (e.g. conifer selection at different seasons) is needed to inform habitat management of native and planted conifer forests to ensure a secure future for this endemic bird.Peer reviewe

Synthesis and Coordination Compounds of A Bis(Imino)Acenaphthene (Bian)-Supported N-Heterocyclic Carbene
No full textThe bis(imino)acenaphthene-supported N-heterocyclic carbene IPr(BIAN) has been prepared by deprotonation of the precursor imidazolium chloride. Treatment of IPr(BIAN) imidazolium chloride with Ag(2)O afforded the silver complex [IPr(BIAN)]AgCl which can be converted into the corresponding gold complex [IPr(BIAN)]AuCl by reaction with (tht)AuCl (tht = tetrahydrothiophene). The iridium complex [IPr(BIAN)]Ir(COD)Cl was prepared by reaction of the imidazolium chloride with KO(t)Bu and [Ir(COD)Cl](2) and subsequently converted to the carbonyl complex [IPr(BIAN)]Ir(CO)(2)Cl by exposure to an atmosphere of CO. All new compounds were characterized by single-crystal X-ray diffraction, multinuclear NMR, MS and HRMS data.Robert A. Welch Foundation F-0003National Science Foundation 0741973Chemistr

No full textProbing expert anticipation with the temporal occlusion paradigm: Experimental investigations of some methodological issues
No full textCopyright @ 2005 Human KineticsTwo experiments were conducted to examine whether the conclusions drawn regarding the timing of anticipatory information pick-up from temporal occlusion studies are influenced by whether (a) the viewing period is of variable or fixed duration and (b) the task is a laboratory-based one with simple responses or a natural one requiring a coupled, interceptive movement response. Skilled and novice tennis players either made pencil-and-paper predictions of service direction (Experiment 1) or attempted to hit return strokes (Experiment 2) to tennis serves while their vision was temporally occluded in either a traditional progressive mode (where more information was revealed in each subsequent occlusion condition) or a moving window mode (where the visual display was only available for a fixed duration with this window shifted to different phases of the service action). Conclusions regarding the timing of information pick-up were generally consistent across display mode and across task setting lending support to the veracity and generalisability of findings regarding perceptual expertise in existing laboratory-based progressive temporal occlusion studies.This study is funded by the Australian Institute of Sport Tennis program
Infiltrating IT into primary care: A case study
No full textWeb based approaches to tracking students on placement are receiving much interest in the field of medical education The work presented here describes a web-based solution to the problem of managing data collection from student encounters with patients whilst on placement. The solution has been developed by postgraduate students under the direction of staff of the health informatics diploma. Specifically, the system allows undergraduate students on placement or in the main hospital to access a web-based front end to a database designed to store the data that they are required to gather. The system also has the important effect of providing a rationale for the provision of electronic communication to the undergraduate students within the context of healthcare delivery. We believe that an additional effect will be to expose practicing healthcare providers to electronic information systems, along with the undergraduates who are trained to use them, and increase the skill base of the practitioners.Unpublished[1] R.C.

Sensitivity to fine-grained and coarse visual information: The effect of blurring on anticipation skill
No full textCopyright @ 2009 Edizione l PozziWe examined skilled tennis players’ ability to perceive fine and coarse information by assessing their ability to predict serve direction under three levels of visual blur. A temporal occlusion design was used in which skilled players viewed serves struck by two players that were occluded at one of four points relative to ball-racquet impact (-320ms, -160ms, 0ms, +160ms) and shown with one of three levels of blur (no blur, 20% blur, 40% blur). Using a within-task criterion to establish good and poor anticipators, the results revealed a significant interaction between anticipation skill and level of blur. Anticipation skill was significantly disrupted in the ‘20% blur’ condition; however, judgment accuracy of both groups then improved in the ‘40% blur’ condition while confidence in judgments declined. We conclude that there is evidence for processing of coarse configural information but that anticipation skill in this task was primarily driven by perception of fine-grained information.This research was supported by a University of Hong Kong Seed Funding for Basic Research grant awarded to the second author
