Acid Test (acid + test)
Selected AbstractsUse of sunflower oil mixed with jojoba and paraffin oils in deep-fat frying processINTERNATIONAL JOURNAL OF FOOD SCIENCE & TECHNOLOGY, Issue 7 2008Radwan S. Farag Summary The aim of the present study was to increase the stability of sunflower oil during frying process and to obtain low-calorie fried foods. Therefore, sunflower oil was mixed separately with jojoba oil and paraffin oil at ratios of 9:1 and 8:2 (v/v). The frying process was conducted at 180 ° ± 5 °C for 12 h continuous heating time. Some physico-chemical properties (refractive index, viscosity, colour, acid value, peroxide value, thiobarbituric acid test, iodine value and polymer content) of non-fried and binary fried oil systems were measured at various heating periods. The results demonstrated that mixing sunflower oil with jojoba oil or paraffin oil increased the stability and hence improved the quality of sunflower oil during frying process.

Verbeke Abstract, The applicability of the 13C-octanoic acid breath test for the assessment of gastric emptying is discussed. In the current issue of this journal, Keller and her colleagues described the application of different mathematical models for analysis of the 13C-octanoic acid test in a very large patient population. [source] THOMAS REID ON MOLYNEUX'S QUESTIONPACIFIC PHILOSOPHICAL QUARTERLY, Issue 3 2005ROBERT HOPKINS The first version is used to address whether there are any properties originally perceived in both touch and vision. Although it is tempting to think the second discussion serves the same purpose, this would render pointless various novel features of the question Reid then frames. Instead, I suggest, Reid's second question provides the acid test of one of his central claims against the Ideal system, that the blind can form a conception of visible figure. The issue is not the cross-modality of perceptual representations, but the amodality of a central concept, as befits the Inquiry's central argumentative ambitions. [source] The ecology of restoration: historical links, emerging issues and unexplored realmsECOLOGY LETTERS, Issue 6 2005T. P. Young Abstract Restoration ecology is a young academic field, but one with enough history to judge it against past and current expectations of the science's potential. The practice of ecological restoration has been identified as providing ideal experimental settings for tests of ecological theory; restoration was to be the ,acid test' of our ecological understanding. Over the past decade, restoration science has gained a strong academic foothold, addressing problems faced by restoration practitioners, bringing new focus to existing ecological theory and fostering a handful of novel ecological ideas. In particular, recent advances in plant community ecology have been strongly linked with issues in ecological restoration. Evolving models of succession, assembly and state-transition are at the heart of both community ecology and ecological restoration. Recent research on seed and recruitment limitation, soil processes, and diversity,function relationships also share strong links to restoration. Further opportunities may lie ahead in the ecology of plant ontogeny, and on the effects of contingency, such as year effects and priority effects. Ecology may inform current restoration practice, but there is considerable room for greater integration between academic scientists and restoration practitioners. [source] Dementia in primary care: the first survey of Irish general practitionersINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 4 2006Suzanne Cahill Abstract Objective To investigate General Practitioners' (GPs) attitudes and practices in relation to screening, diagnosing, and disclosing a dementia diagnosis to patients. Design National postal survey. Participants A random sample of 600 GPs from a national database of 2400. Results Of the 600 GPs surveyed, 60% returned questionnaires of which 50% (300) were useable. GPs reported diagnosing on average four new cases of dementia annually. A multivariate analysis revealed that females diagnosed significantly fewer cases annually (t,=,5.532, df,=,289, p,<,0.001). A large majority of GPs reported performing thyroid function tests (77%), B12 (75%) and Folic acid tests (75%) to out rule reversible causes of cognitive impairment. The most reliable signs and symptoms of dementia identified were memory problems (58%). Main barriers to diagnosis were difficulty differentiating normal ageing from symptoms of dementia (31%), lack of confidence (30%) and the impact of the diagnosis on the patient (28%). GPs' age (,2,=,14.592, df,=,3, p,<,0.005) and gender (,2,=,11.436, df,=,3, p,<,0.01) were significantly associated with barriers to diagnosis. Only 19% claimed they often or always disclosed a diagnosis to a patient. Over one-third of GPs (38%) reported that the key factor influencing their disclosure patterns was their perceptions of the patient's level of comprehension. Most GPs (90%) had never undergone any dementia specific training and most (83%) expressed a desire for this. Conclusions GPs experience difficulty diagnosing and disclosing a diagnosis of dementia to patients. To improve dementia care in Ireland, there is an urgent need to develop an active and more systematic approach to GP training in dementia care. Copyright © 2006 John Wiley & Sons, Ltd. [source] |
