Ba4LaTi0.3Sn0.7O15ceramic was prepared through conventional solid state mix oxide route followed by characterization using X-ray diffraction (XRD) and scanning electron microscope (SEM) for phase and microstructural investigation. The dielectric properties at low and microwave frequencies were measured using LCR meter…
OBJECTIVE: To test whether breakdown of the blood-brain barrier (BBB) occurs during migraine attacks. BACKGROUND: It has been discussed for decades whether a breakdown of the BBB might facilitate migraine medications, such as dihydroergotamine (DHE), gaining access to central sites of action despite unfavorable physic…
We performed first-principles calculations for two Mn -doped structures in which Mn atoms substitute Ti atoms to determine whether (i) it is more conducive to Mn ion doping and (ii) ferromagnetism can occur in F adsorption anatase TiO 2 surfaces. Ferromagnetic (FM) coupling is more stable than antiferromagnetic (AFM)…
In this paper, three-dimensional (3D) Cu 0.45 Mn 0.55 O 2 nanoflowers self-assembled by interconnecting dense stacked single-crystalline nanoplates have been prepared using the template-free hydrothermal growth method. The morphology, phase structure and composition of the as-prepared nanomaterial were characterized b…
By laser melting technique, TiCxNy ceramics are prepared under the laser powers of 300, 400, 500, 600, and 700 W, respectively. The size of molten pool decreases with the increase of scanning speed from 1 to 4 mm/s at a certain power. TiCxNy microstructure continuously changes from the top to bottom of molten pool. Ba…
In this paper, shift multiplex recording of phase data pages on a volume polarization-sensitive medium by retardagraphy is demonstrated. The origin of shift selectivity in volume retardagraphy is explained. In the experiment, four-valued phase data pages are used. Then, a coding method is proposed to correct a reconst…
We propose and study a model of polymer chains in a bilayer. Each chain is confined in one of the layers and polymer bonds on first neighbor edges in different layers interact. We also define and comment results for a model with interactions between monomers on first neighbor sites of different layers. The thermodynam…
In this paper, we investigate a magnetic diffusion field (MDF) within a guided wave wire, and analyze a one-to-one mapping between the MDF and the signal of a magnetostrictive position sensor (MPS). In order to control the MDF, two approaches—a magnetism absorption strap (MAS) and a magnetized MAS—are proposed. On the…
OBJECTIVE: To validate the use of VSAQ to estimate exercise capacity in ambALS. BACKGROUND: Many ambALS want to know how much exercise they should exercise and how much exercise should the do. Exercise prescription should be tailored to patients’ tolerant and functional capacity. The cardiopulmonary exercise test is t…
OBJECTIVE: To evaluate predictors of outcome in Amyotrophic Lateral Sclerosis (ALS) using a large patient cohort who underwent longitudinal standardized assessments. BACKGROUND: Improved disease progression prognostication in ALS would guide patient care and improve statistical power of trials. DESIGN/METHODS: Data we…
Abstract The crystallization of hybrid molybdates invariably involves reaction of appropriate molybdenum source and organic bases in a suitable solvent. The outcome of the crystallization process depends on the nature of the condition favoring a particular supramolecular assembly. In this work, it was aimed to utilize…
OBJECTIVE: To systematically review the relationship between sex steroid hormones and neuroprotection in Parkinson’s Disease (PD). BACKGROUND: Sex is a major contributor to the risk of developing PD, with a relative risk of 1.5 in males compared to females, and estrogen may account for this difference. It has been sho…
An intriguing question is how thermophilic organisms, in particular hyperthermophilic ones, cope with heat-sensitive thermolabile metabolites. Important phosphorylated metabolites, also used in glucose metabolism, are ATP and ADP. The comparison of the hyperthermophilic enzymes for tryptophan synthesis with the mesoph…
In this Comment, I point out that the physical origin of molecular tilt in the smectic phase, found in the Monte Carlo simulations of systems of rodlike molecules with two terminal antiparallel transverse dipole moments by Bose and Saha [Phys. Rev. E 86, 050701(R) (2012)], is similar to the one proposed by McMillan. I…
OBJECTIVE: To evaluate cerebral oxidative stress in amyotrophic lateral sclerosis (ALS), we applied positron emission tomography (PET) with [ 62 Cu]diacetyl-bis( N 4 -methylthiosemicarbazone) ( 62 Cu-ATSM) to ALS patients. BACKGROUND: The effects of oxidative stress and mitochondrial dysfunction on neurodegeneration i…
ABSTRAK Seiring meningkatnya perindustrian di era globalisasi dan kemajuan teknologi yang terus berkembang. hal ini mengakibatkan munculnya benda-benda tak habis pakai (limbah) menumpuk. Salah satu limbah yang belum begitu banyak diteliti sebagai bahan dalam campuran beton yaitu tetes tebu (molase). Pada penelitian in…
Wettability of an iron surface is crucial for the wide applications of iron in practice. In this work, a hierarchical structure highly similar to that of the underside of a bamboo leaf was constructed on an iron surface via the template method and controllable etching. After modification by stearic acid, the iron surf…
An attempt is made to highlight the importance of inhomogeneities in hydrogenated amorphous silicon (a-Si:H), in controlling its electronic properties. We note that hydrogen increases the gap in a-Si:H and that hydrogen is distributed inhomogeneously in it. This gives rise to long-range potential fluctuations, which a…
The author undertook a systematic screening of the inducing capacity of all available thiogalactosides, of their affinity to the purified β-galactosidase, and of their “apparent affinity” to the intracellular enzyme. Constitutive strains, which synthesized β-galactosidase in media devoid of inducer, had been isolated.…
This chapter summarizes the knowledge about the genomes of psychrophilic bacteria, a subclass of the cold-adapted bacteria, with emphasis on the specific selective features relevant to cold adaptation. A detailed analysis of the general features of genomes and proteomes from psychrophilic bacteria is presented. All in…
