Abstract A prerequisite for starting a clinical trial is evidence of a positive impact of the technique or drug in animals. The choice of the animal model is thus very important and should mimic as closely as possible the human situation. A variety of animal models have been validated for pharmaceutical trials. The si…
The aim of this investigation was to understand the localised failure behaviour of diamond like carbon (DLC) thin film during multiple-cycle repeating nanoindentation. The film investigated was 100 nm and 500 nm thick sputtered coated on two Si (100) wafers of 500 m thickness. Multiple-cycle repeating nano-indentatio…

Even when the charging of lapping plates can extensively influence their subsequent finishing performance, the subject has been scarcely treated in specialized literature. The present paper aims to help fill such a gap and gain a better insight of the charging process. A semiquantification of the diamond particles int…
The title compound, [Ni(C(28)H(28)N(4))], crystallizes with two independent mol-ecules in the unit cell, one of which is located on an inversion center. Both macrocycles exhibit a planar conformation with average deviation from the least-squares-plane of the 24 macrocycle atoms of Δ24 = 0.043 Å for the first mol-ecule…
Powders are perhaps the oldest means for visualizing prints and have been in use since the late nineteenth century [1]. Over the years, a considerable number of organic and inorganic materials have been used to make powders. Several references provide a detailed description of the early development and chemistry of po…
Corn syrup films are used to replicate holograms in order to fabricate micro-structural patterns without the toxins commonly found in photosensitive salts and dyes. We use amplitude and relief masks with lithographic techniques and rubbing techniques in order to transfer holographic information to corn syrup material.…
Nanocrystalline silver dressings are widely known to be potent antimicrobial and anti-inflammatory agents and have long been used to treat topical wounds. Gold is known to be a strong anti-inflammatory agent and has been used in the treatment of rheumatoid arthritis for >70 years. The purpose of this work was to study…
Denitration of a highly concentrated sodium nitrate (NaNO3) aqueous solution via a catalytic reduction method using a palladium–copper catalyst supported on carbon powder (Pd–Cu/C) and hydrazine (N2H4) was investigated. It was demonstrated that nitrate ion (NO3 −) in a 5 mol L−1 NaNO3 solution was completely reduced t…
Within the presented work the effects of rotation and strain on the bubble dynamics inside a cavitating cloud is analyzed and discussed. To follow this task, the mixture of cavitation bubbles and liquid is treated as a continuous medium. With the Helmholtz vortex theorem in mind a torus is considered to be preferable…
Vertically aligned carbon nanotube (VACNT) films were synthesized and investigated in vitro for their potential use as a neural stimulation electrode. Materials and electrochemical (EC) characterization (cyclic voltammetry, electrochemical impedance spectroscopy, and high-rate potential transient measurements) were pe…
One of the most popular and simple models for the calculation of pK(a) s from a protein structure is the semi-macroscopic electrostatic model MEAD. This model requires empirical parameters for each residue to calculate pK(a) s. Analysis of current, widely used empirical parameters for cysteine residues showed that the…
We synthesized a novel discotic liquid crystalline compound, octakis[3-(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)phenoxy]phthalocyaninato copper(II) (abbreviated as [m- MeO(EtO)3PhO]8PcCu ), and established the mesomorphism by using a differential scanning calorimeter, a polarizing optical microscope, and temperature-depen…
Abstract The literature presents different methods for quantifying and characterizing partially hydrolyzed polyacrylamide (HPAM) in solution. However, only a few of these are suitable for determining the critical overlap concentration (C*). The evaluation of C* is important for describing the transition from the dilut…
Instrumental techniques: The main crystalline phases were analyzed by means of X-ray diffraction (XRD). The presence of portlandite and calcium carbonate phases has been determined in concrete samples affected no affected by fire.
In the title compound, [Mn(C(13)H(16)N(6)O)(CO)(3)](CF(3)O(3)S), the Mn(I) atom has a slightly distorted octa-hedral geometry. The three CO ligands have C-Mn-C angles in the range 89.44 (10)-92.31 (9)°, while the three N atoms of the tripodal ligand form significantly smaller N-Mn-N angles of 82.76 (2)-85.51 (6)°. The…
CANDLE (Constant Axial shape of Neutron flux, nuclide number densities and power shape During Life of Energy producing reactor) reactors have been intensively researched in the last decades [1–6]. Research shows that this kind of reactor is highly economical, safe and efficiently saves resources, thus extending large…
以Ho为掺杂元素, 采用热压烧结方法制备Bi 4- x Ho x Ti 3 O 12 陶瓷, 重点研究了Ho掺杂量对其物相组成、致密度、微观结构和铁电性能的影响. 首先以Bi 2 O 3 、TiO 2 和Ho 2 O 3 微粉为原料, 利用固相反应在900℃合成出主晶相为Bi 4 Ti 3 O 12 的Bi 4- x Ho x Ti 3 O 12 ( x =0~0.8)粉体; 然后, 将合成粉体在850℃、30 MPa条件下热压烧结, 当Ho掺杂量 x =0~0.4得到了物相单一、整体致密(>99%)的Bi 4- x Ho x Ti 3 O 12 陶瓷. 随Ho掺杂量的增加, Bi 4- x Ho x Ti 3 O 12 陶瓷的剩…
In this paper, we propose an analytical method to predict projectile penetration and perforation based on the Differential Area Force Law (DAFL) and semiempirical resistance function. Due to the free surface effect, in order to account for the differences of the target resistances acting on the top and bottom sides of…
In the title salt, (C(16)H(36)N)[Fe(C(3)H(9)OSi)(4)], the cation contains a central N atom bonded to four n-butyl alkyl groups in a tetra-hedral arrangement, while the anion contains a central Fe(III) atom tetra-hedrally coordinated by four trimethyl-silanolate ligands.
