Measuring D -spacing values from collagen fibrils or collagen fascicles with surface curvatures will introduce additional errors. This error might be minimized by studying single collagen fibrils which are parallel to the surface of substrates.
In recent years, window-integrated solar protection systems are used and studied as a promising energy saving technology, both for cold and hot climates. In particular, smart windows, whose optical proprieties in the solar wavelength range can somehow be controlled, show interesting results, especially in reducing the…
Considered clean water in swimming pools, on nonionic and anionic surfactants with special adsorbents. Water purification pools plavatelnyx unique, first of all, because the water contains various types of pollution, which it is exposed. Most of these contaminants are introduced by the users of the swimming pool and t…
We revisit an antiferromagnetic quantum phase transition with $\mathbit{Q}=2{\mathbit{k}}_{F}$, where $\mathbit{Q}$ is an ordering wave vector and ${\mathbit{k}}_{F}$ is a Fermi momentum. Reformulating the Hertz-Moriya-Millis theory within the strong-coupling approach to diagonalize the spin-fermion coupling term and…
Purpose. As a rule secondary silumins are characterized by lower quality than their primary analogues. During manufacture of alloys a large quantity of intermetallides, first of all on the basis of iron, in their structure is ignored. To achieve the optimum level of properties it is necessary to search for ways to ada…
Purpose. Most of the freight traffic in Ukraine is made by railway transport. Government statistics of annual railway freight traffic (January-November) records the following data: 2011 - 468 million tons (108.2% to 2010); 2012 – 421.5 million tons (98.5% to 2011); 2013 – 441.8 million tons (96.6% by 2012). Despite th…
Iodine is one of the major contributors to the source term during a severe accident in a Nuclear Power Plant for its volatility and high radiological consequences. Therefore, large efforts have been made to describe the Iodine behaviour during an accident, especially in the containment system. Due to the lack of exper…
In protein nanocrystallography using x-ray lasers, diffraction is measured from an ensemble of very small crystals. The measured diffraction data can sometimes be processed to estimate the continuous Fourier transform intensity of the contents within the unit cell that makes up the crystals. However, in most cases the…
An investigation of the electronic structure of some transition metal clusters comprising anti-ferromagnetically coupled, heterometallic arrays of eight metal ions that are wheel-shaped, is reported.The compounds were synthesized and provided by Dr. Grigore Timco of The University of Manchester and are formulated by t…

Os Antiinflamatorios nao esteroidais (AINES) sao os agentes farmacologicos mais utilizados na pratica medica e apresentam atividade analgesica, antipiretica e anti-inflamatoria, dentre esses compostos destaca-se o diclofenaco de sodio
Pelayanan uji kontaminasi radionuklida dalam bahan makanan, bahan bangunan dan komponen lingkungan beserta sertifikasi komoditi ekspor-impor adalah bagian dari tugas dan fungsi Puslitbang Keselamatan Radiasi dan Biomedika Nuklir (P3KRBiN), Badan Tenaga Nuklir Nasional. Untuk menunjang pelaksanaan tugas ini, P3KRBiN me…
First principles calculations based on density functional theory were employed to investigate the structural, electronic, and magnetic properties of the Sc x Cr 1-x N (x =0.0, 0.25, 0.50, 0.75, and 1.0) compound, in the wurtzite structure. We applied the full-potential linearized augmented plane wave (FP-LAPW) method…
Limitation of orbital debris accumulation is an international and national concern, reflectedin NASA debris limitation requirements. These requirements will be reviewed, along with some practices that can be employed to achieve the requirements.
Soybean oil-based resin for transparent flexible coating applications were formulated by dihydroxyl soybean oil (DSO) with commercial epoxy monomers (i.e., epoxidized soybean oil (ESO) and 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexanecarboxylate (ECHM)). The resin was formed to thermoset polymers using cationic ring-…
In this paper we devise and analyze an unconditionally stable,\nsecond-order-in-time numerical scheme for the Cahn-Hilliard equation in two and\nthree space dimensions. We prove that our two-step scheme is unconditionally\nenergy stable and unconditionally uniquely solvable. Furthermore, we show that\nthe discrete pha…
Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
We address the problem of reaching consensus in the presence of Byzantine faults. In particular, we are interested in investigating the impact of messages relay on the network connectivity for a correct iterative approximate Byzantine consensus algorithm to exist. The network is modeled by a simple directed graph. We…
The letter report provides a compilation of yield and cavity radius information for all underground nuclear tests with specified yields reported in DOE/NV -- 209-REV 15 (2000). Yield data were taken directly from DON/NV -- 209-REV 15 (2000). Cavity radius information was taken from a personal computer based database r…
Coherent control of the nitrogen-vacancy (NV) center in diamond's triplet spin state has traditionally been accomplished with resonant ac magnetic fields under the constraint of the magnetic dipole selection rule, which forbids direct control of the $|-1>\leftrightarrow |+1>$ spin transition. We show that high-frequen…
