The use of a waste-based secondary fuel in clinker kilns is a widely used practice. Nevertheless, specific studies to understand the destruction mechanism of exhaust pollutants in cement raw material (CRM) are limited. This work focuses on the possible catalytic effect of the interaction of exhaust gases from the comb…
Effects of crystal structures on dielectric properties of ATiO 3 (trigonal ilmenite), ATa 2 O 6 (tetragonal tri-rutile) and AWO 4 (monoclinic wolframite) (A = Ni, Mg, Co) ceramics with A- and B-site oxygen octahedra were investigated at microwave frequencies. The dielectric constant (K) of the specimens was affected b…
In this study, we aimed to replicate the function of native tissues that can be used in tissue engineering and regenerative medicine. The key to such replication is the preparation of an artificial collagen matrix that possesses a structure resembling that of the extracellular matrix. We, therefore, prepared a collage…
The complexation of Eu3+ with doxycycline (DC) antibiotic in the presence of several second ligands and surfactant micelles of different types is studied by the spectrophotometric and luminescence methods. It is found that the efficiency of excitation energy transfer in Eu3+-DC chelate depends on the nature of the sec…
Biomimetic superhydrophobic surface was fabricated by replicating topography of the fresh fish skin surface ofNavodon septentrionaliswith polydimethylsiloxane (PDMS) elastomer. A two-step replicating method was developed to make the surface structure of the fresh fish skin be replicated with high fidelity. After dupli…
In this manuscript in situRAFT polymerization inside reactive triblock copolymer micelles were reported. Poly(ethylene glycol)-block-poly(2-hydroxyethyl methacrylate)-block-poly(tert-butyl acrylate) (PEG-b-PHEMA-b-PtBA) triblock copolymer was synthesized through two-step ATRP of HEMA and tBA by using ATRP initiator te…
By using the ultra-soft pseudo-potential approach of the plane wave based on the density-functional theory, the electronic structures and optical properties of LiF with Li-1 and F+1 vacancies are calculated. The results indicate that: (1) the presence of the vacancy causes defective states within the band gap of LiF;…
We report on the generation and stability of half-strength twist disclination loops separating planar and π-twisted regions in a bent-core nematic liquid crystal with planar anchoring. Loops L(P) and L(T) surrounding planar and π-twisted domains, respectively, are both generated during relaxation from the quasi-homeot…
In a turbo molecular pump suspended by active magnetic bearings (AMBs), vibration caused by the rotor’s bending modes, gyroscopic effects and structure vibration modes influenced the pump performance and even cause instability. Different methods were used to deal with these problems. A Cross Feedback method was effect…
A thiocyanate ion selective poly(aniline) solid contact electrode based on manganese complex of N,N’-bis-(4-phenylazosalicylidene)-o-phenylene diamine ionophore was successfully developed. The electrode exhibits a good linear response of 58.1 mV/decade (at 20?C ± 0.2?C, r2 = 0.998) with in the concentration range of 1…
Xylan dissolved during kraft cooking and later redeposited on fibre surfaces has been demonstrated to affect paper strength properties. Earlier studies have demonstrated that it is the xylan charac ...
Endopleura uchi (Huber) Cuatrec. (Humiriaceae), a Brazilian Amazon plant, is used in folk medicine for the treatment of arthritis. Bergenin, one of the chemical constituents of E. uchi, has several biological activities, including anti-inflammatory properties. Acetylbergenin was obtained from acetylation of bergenin t…
A study to determine biodiversity related to ecological function of secondary mangrove forests at central Java had been carried out in three different locations viz. Rembang, Demak and Pemalang coasts. Location of sampling was selected systematically in three levels of inundation within both lower and higher densities…
Two associated shrink - swell soils (red and gray coloured) occurring in a catena in the Hingoli district of Maharashtra were taken for this study. Detailed study of the morpho logical, physical and chemical properties indicated that both the soils have Vertisol characteristics. The low hydraulic conductivity of red V…
Polymer quenchants are being used increasingly in the heat treating industry. One reason for this increase is the continual engineering advancements that facilitate their replacement for quench oils and water. The physical properties of a polymer quench bath directly affect the cooling rate of a quenched part. These p…
A 47-year-old female school teacher with a six-week history of left-sided scapular and arm pain is presented. We report her evaluation and treatment Although lumbar degenerative synovial cysts have been reported over 200 times in the literature,6 cervical synovial cysts are much more rare. This case reports a cervicot…
Particle Filled Polyethylene Composites Used in the Technology of Rotational Moulding The submitted article discusses rotational moulding technology and filled plastics. For testing, linear low density polyethylene filled with talc was used. The materials tested varied way of mixing the filler into the polymer. For th…

This paper presents a 3-phase, 4-wire unified series-parallel active filter (USPAF) system for periodic and nonperiodic disturbance compensation using a generalized nonactive power theory. The USPAF system consists of a series active filter (AF), parallel AF, and split DC-link capacitors with the midpoint of the DC-li…
Resistance of antichemical clothing primarily depends on the type of material it is made from, in particular on the type of polymer used for coating the fabric carrier. This paper reports on systematic investigations on the influence of the cross-linking density of an elastomer and the composition of a cross-linked el…
