Role of complexes formation between drugs and penetration enhancers in transdermal delivery
(Elsevier, 2008)
The use of chemical penetration enhancers (CPE) is growing due to their ability to improve drug delivery through the skin. A possible mechanism of penetration enhancement could involve the complex formation between drug ...
Slow-wave EBG microstrip rat-race hybrid ring
(Iee-Inst Elec Eng, Hertford, 2005)
A new type of slow-wave EBG microstr p rat-race hybrid ring is presented. It effectively reduces the occupied area to 11% of the conventional rat-race hybrid ring. It does not need any impedance transformers on the ports.
Comparison of two methods for removal of arsenic from potable water
(Vacuum, 2008)
Arsenic, well known of its toxicity, is present in potable water in many areas in the world, as well as in underground water used for water supply in Vojvodina, a region in Serbia. Its removal from raw water is necessary ...
Pulse and direct current plating of Ni-W alloys from ammonia-citrate electrolyte
(Elsevier, 2006)
The effect of the potential of deposition and electrode rotation rate on current efficiency and partial current density of nickel deposition from ammonia-citrate electrolyte with and without tungstate ions was investigated. ...
Geochemical investigation and characterisation of Neogene sediments from Valjevo-Mionica Basin (Serbia)
(Springer, New York, 2009)
Sediments from the Valjevo-Mionica Basin of Neogene age were investigated in this study using different geochemical methods. The results of the inorganic part analyses suggest that during genesis of the sediments, the ...
pH-Dependent Leaching of Dump Coal Ash-Retrospective Environmental Analysis
(Taylor & Francis Inc, Philadelphia, 2009)
Trace and major elements in coal ash particles from dump of "Nikola Tesla A" power plant in Obrenovac near Belgrade (Serbia) can cause pollution, due to leaching by atmospheric and surface waters. In order to assess this ...
Purification and properties of midgut α-amylase isolated from Morimus funereus (Coleoptera: Cerambycidae) larvae
(Elsevier Science Inc, New York, 2008)
Using soluble starch as a substrate five isoforms of α-amylase were identified in a crude extract of Morimus funereus larvae. The main α-amylase (termed AMF-3) was purified by gel filtration chromatography and anion exchange ...
High-yield synthesis of substituted and unsubstituted pyridinium salts containing a 4-oxothiazolidine moiety
(Georg Thieme Verlag Kg, Stuttgart, 2008)
A new series of unsubstituted and substituted pyridinium salts bearing a 4-oxothiazolidinyl moiety has been prepared by an efficient rearrangement of 2-(l-bromoalkylidene)thiazolidin-4-ones. The process is based on three ...
Effects of O2+ ions beam irradiation on crystal structure of rare earth sesquioxides
(Elsevier, 2009)
We report the results of ion irradiation influence on rare earth sesquioxides structure, which are materials of practical importance as a radiation resistant ceramics in nuclear applications. Y2O3, Gd2O3 and Er2O3 sesquioxides ...
1-Cinnamyl-4-(2-methoxyphenyl)piperazines: Synthesis, binding properties, and docking to dopamine (D2) and serotonin (5-HT1A) receptors
(Wiley-V C H Verlag Gmbh, Weinheim, 2007)
Clinical properties of atypical antipsychotics are based on their interaction with D2 dopamine receptor and serotonin 5-HT1A and 5-HT2A receptors. As a part of our research program on new antipsychotics, we synthesized ...
