In practice, it is necessary to implement an incremental and active learning for a learning method. In terms of such implementation, this paper shows that the previously discussed S-L projection learning is inappropriate to constructing a family of projection learning, and proposes a new version called partial oblique projection (POP) learning. In POP learning, a function space is decomposed in...

This study evaluates perceptual changes in speech production accuracy in six children (3-11 years) with moderate-to-severe speech impairment associated with cerebral palsy before, during, and after participation in a motor-speech intervention program (Prompts for Restructuring Oral Muscular Phonetic Targets). An A1BCA2 single subject research design was implemented. Subsequent to the baseline p...

OBJECTIVE To estimate the degree of internal exposure to organochlorine pesticides (persistent organic pollutants, POP) among inhabitants of an open-air dump. METHODS This was an observational study with simultaneous measurement and control, in which the criterion for subjects was that they dwelled in an area contaminated by POP and the effect of such contamination was the concentration of su...

Background and aims: Pelvic organ prolapse (POP) is a common condition which affects on a large proportion of women. The objective of this study was to determine the risk factors of POP in Iranian women. Methods: This cross-sectional study was carried out to examine the role of demographic, anthropometric and clinical characteristics in POP disease in a sample of 365 females in Ilam, Iran. Exa...

Summary Cyclopropane-functionalized hydrocarbons are excellent fuels due their high energy density. However, the organic synthesis of these molecules is challenging. In this work, we produced polycyclopropanated fatty acids in bacteria. These can be converted into renewable for energy-demanding applications such as shipping, long-haul transport, aviation, and rocketry. We explored chem...

objective: evaluating the effect of dentin conditioning with edta on microleakage of composite resin restorations, using two etch and rinse and two self-etch adhesives. materials and methods: one hundred and sixty extracted molars received class v cavity preparations right under the cej and were randomly divided into eight groups of 20, usingfour different adhesive systems. these adhesives incl...

This study was designed to evaluate microleakage that appeared on Resin-Modified Glass-Ionomer Cement (RMGIC) restorations. Sixty class V cavities (h x w x l = 2 mm x 2 mm x 3 mm) were cut on thirty extracted third molars, which were randomly allocated to three experimental groups. All the buccal cavities were pretreated with polyacrylic acid, whereas the lingual cavities were treated with thre...

The mobility, durability, and widespread use of perfluorinated polyfluoroalkyl substances (PFAS), notably perfluorooctanoic acid (PFOA), bring about serious contamination many ground surface waters. In this study, fluorine amine-functionalized porous organic polymer (POP-4F) was designed successfully synthesized as an adsorbent for PFOA removal in water. characterization results showed that the...
