Bisphosphonates are used against osteoporosis and Paget’s disease. Despite their benefits; bisphosphonates suffers from poor oral bioavailability (1�2%). Bilayered multipolymeric films comprising of risedronate sodium with chitosan (85% deacetylated) and hydroxypropylmehtyl cellulose (HPMC 4KM) interpolymer complex of…
Regional cerebral blood flow (CBF) can be quantified using oxygen-15-labelled water ([15O]H2O) and positron emission tomography. In this overview, first a description is given of the early methods developed for the first generation of PET scanners in which the volume of distribution of water (V T) had to be fixed. Nex…
The beta-sheet and alpha-helix peptide conformation are two of the most fundamentally ordered secondary structures found in proteins and peptides. They also give rise to self-assembling motifs that form macromolecular channels and nanostructures. Through design these conformations can yield enhanced membrane activity.…
Nanotoxicity, the potential of nanosized objects to cause harm to an organism, is a complex discipline, requiring the close collaboration between life and material sciences. In this context, it has become crucial to identify key parameters in the physico-chemical properties of nanomaterials that can...
Magnetic gears can transmit torque without mechanical contact. They therefore have low vibration and acoustic noise, and are low maintenance in comparison with conventional mechanical gears. Various types of magnetic gears have been introduced. A planetary type magnetic gear has attracted interest recently because of…

The structural, the magnetic, the transport and the half-metallic properties of quaternary Heusler alloy Fe2Co1-xCrxSi are investigated. The studies of X-ray diffraction and temperature dependence of magnetization reveal that Fe2Co1-xCrxSi alloy always maintains a high degree of order, while the Curie temperature decr…
The history of the concept of protein folds is discussed, starting with the original concept of super-secondary structure. This has led to the recognition of a fairly small number of distinct folds defining individual domains within larger proteins. Each fold can usually be associated with a specific function. Thus th…
All living systems depend on metalloproteins. Yet, while tools for the separation and identification of apo-proteins are well developed, those enabling identification and quantitation of individual metalloproteins within complex mixtures are still nascent. Here, we describe the electrophoretic separation of a mixture…
Protein structures and their complexes are formed and stabilized by interactions, both inside and outside of the protein. Analysis of such interactions helps in understanding different levels of structures (secondary, super-secondary, and oligomeric states). It can also assist molecular biologists in understanding str…
Conjugated polymers (CPs) are macromolecules with polymeric backbones composed of double or triple bonds of carbon linked by single bonds. This highly delocalized π-conjugated feature gives rise to the semiconductor characteristic of conjugated polymers. The electro- and photoluminescent characteris...
The latest studies of fluid inclusions in Zletovo Mine were performed on quartz samples from the ore veins No. 2, 3 and 8. The quartz samples were selected from main ore parageneses where have dominated galena and sphalerite, followed by pyrite, chalcopyrite, calcite, kaolinite etc. Homogenization temperatures were wi…
Optical microscopy is a simple yet robust strategy to study live cellular processes. By changing the wavelength of the illumination light, different non-fluorescent nanoparticle probes can be identified and tracked dynamically inside crowded living cells with either differential interference contrast (DIC) microscopy…
Microorganisms from extreme environments are often very difficult to cultivate, precluding detailed study by biochemical and physiological techniques. Recent advances in genomic sequencing and proteomic measurements of samples obtained from natural communities have allowed new access to these uncultivated extremophile…
The importance of detecting accurately the partial discharge in high voltage power industry becomes obvious as the infrastructure ages. In this work electromagnetic sensing for detecting the electromagnetic radiation, associated with partial discharge, in an air-insulated medium voltage switchgear (Type D24-121114 of…
Biofouling by marine organisms such as algae and barnacles causes lots of significant problems in marine systems such as a rise of the maintenance-repair cost for the ship and the marine structures. In this work, a fluoropolymer, perfluoropolyether (PFPE), was applied as an anti-biofouling coating material that preven…
Anatase and anatase/rutile samples were prepared at /TTIP molar ratio of 0.1, 0.5, 1.0, and 1.5 to study the effects of the physical properties of on photocatalytic decomposition of methylene blue. The physical properties of the samples were measured with XRD, SEM, TEM, BET, FT-IR, and UV-vis spectroscopy. Anatase pha…
Dielectric barrier discharge in a two-phase mixture(TPM-DBD) with considerable advantages of high efficiency,low energy consumption and higher energy density at the atmospheric pressure,has been widely used in exhaust gas treatment.An important factor affecting the reaction efficiency is the way of filling solid beads…
It is particularly important to appropriately compact the chopped material upon storage to produce high quality silage feed. It was the objective of the research to understand the metrological prerequisites for online density measuring using a radiometric probe. Caesium 137 with an activity of 37 MBq was used as radia…
For a severe accident of nuclear power plant, an approach to estimation of the radiological source term using a severe accident code(MELCOR) has been proposed. Although the MELCOR code has a capability to estimate the radiological source term, it has been hardly utilized for the radiological consequence analysis mainl…
