: The copper T intrauterine contraceptive device (IUCD) is a widely used reversible method all over the world today. They are effective and recommended for use up to 10 years. Intrauterine as spacing in many couples. Some of causes removal include desire pregnancy sterilization etc. To determine efficacy T(Cu T) 380 A method. indications discontinuation Cu A. identify difficulties faced during ...

A benzimidazole appended triazole linked 1,3-diconjugate of calix[4]arene (L) has been synthesized and characterized. The conjugate L has been found to recognize Cu(2+) among the thirteen different metal ions studied by exhibiting ratiometric fluorescence changes through newly generated excimer band at ∼380 nm. Fluorescence off-on-off behavior has been clearly demonstrated on the basis of the b...

The paper presents an application of the Skyhook control of suspension MR dampers in a vehicular vibration control system. Experiments were conducted using an ATV (all-terrain vehicle) traversing a test route. The system elements were analyzed and calibrated paying special attention to the space orientation of sensors and MR dampers. Orientation data and inversed Bingham model, which maps dynam...

O steoporosis is a systemic disorder characterized by microarchitectural deterioration of bone and increased susceptibility to fracture. Although osteoporosis can occur in men, it is principally a disease of women, who account for 80% of such cases and in whom osteoporosis (together with heart disease and cancer) is one of the three most common medical conditions.1-3 According to the National O...

Although the Cu(2+)-binding sites of the prion protein have been well studied when the protein is fully saturated by Cu(2+), the Cu(2+)-loading mechanism is just beginning to come into view. Because the Cu(2+)-binding modes at low and intermediate Cu(2+) occupancy necessarily represent the highest-affinity binding modes, these are very likely populated under physiological conditions, and it is ...

BACKGROUND Soil contamination by copper (Cu) and lead (Pb) is a widespread environmental problem. For phytoextraction to be successful and viable in environmental remediation, strategies that can improve plant uptake must be identified. In the present study we investigated the use of nitrogen (N) fertilizer as an efficient way to enhance accumulation of Cu and Pb from contaminated industrial so...

Effects of copper (Cu) and aluminum (Al) on the adsorption of sulfathiazole (STZ) and tylosin (T) to peat and soil were investigated using a batch equilibration method. Results show that Cu suppressed STZ adsorption onto peat and soil at pH < 5.0 because of the electrostatic competition, while increased STZ adsorption at pH > 5.0 due to the formation of STZ-Cu complexes and/or Cu bridge. In con...

Octanoic acid (OA) was used as reactant with medium chain length to model the aliphatic carboxylic acids which can be produced by catalytic, thermochemical or biological degradation of biomass. A flow through reactor was applied at 21 bar total pressure (in general at 20 bar hydrogen and 1 bar octanoic acid partial pressures) and 330-380 °C. Cu A-, Xand Y-zeolite based catalysts were pretreated...
