It is well known that most crystals which show Reststrahlen behavior are nearly transparent at low temperatures for far-infrared radiation at frequencies below the infrared active eigen-frequency. The crystals are nearly opaque at room temperature due to strong absorption by phonon combination processes [1]. We report experimental results which show that for T1C1 a pronounced LA-TA two phonon d...

The toxigenic potential of Alternaria strains isolated from Argentinean wheat was investigated. A total of 123 strains were assayed for the production of tenuazonic acid (TA), alternariol (AOH) and alternariol monomethyl ether (AME). All but one of the isolates were able to produce at least one of the three mycotoxins. TA was produced by 72% of the strains (1-14782 mg/kg), AOH by 87% (4-622 mg/...

We study the electronic transport in a one-dimensional disordered chair with bath site-diagonal and off-diagonal (hopping) disorder, the latter being perfectly correlated ta the diagonal disorder at the nearest neighbor sites in a linear fashion. Since we allow the hopping m the perfect leads ta be dilferent from the average hopping in the sample, the

The TiO₂(B)/anatase dual-phase nanofiber exhibits enhanced photocatalytic activity when interfaces form during phase transformation of TiO₂. To precisely control the formation of coherent interfaces between TiO₂(B) and anatase, a thorough knowledge of phase transformation particularly from TiO₂(B) to anatase (TA) is required. In our study, a crystallographic model in conjunction with transmissi...

Abstract The aim of the research was to evaluate effect three types silver nanoparticles (AgNPs) with different physicochemical properties and ions delivered in form nitrate (AgNO 3 ) at concentration 50 mg L −1 on germination initial growth monocots (common wheat, sorghum) dicots (garden cress, white mustard). AgNPs were prepared using trisodium citrate (TCSB-AgNPs), tannic acid (TA-AgNPs), cy...

Eleven enzymes were measured in individual fibers of soleus and tibialis anterior (TA) muscles from two flight and two control (synchronous) animals. There were five enzymes of glycogenolytic metabolism: phosphorylase, glucose-6-phosphate isomerase, glycerol-3-phosphate dehydrogenase, pyruvate kinase, and lactate dehydrogenase (group GLY); five of oxidative metabolism: citrate synthase, malate ...

The wide variety of uses for nanoparticles (NPs) is due to their unique combination features in a single assembly. arc melted copper-cobalt ingot sample were qualitatively studied using laser induced breakdown spectroscopy (LIBS). Later, the fabricated alloy as target material Nd:YAG ablation, CuCo2O4 NPs synthesized. magnetic properties synthesized vibrating magnetometer (VSM). To determine co...

Results from imaging studies and finite element models suggest epimuscular myofascial effects on sarcomere lengths in series within muscle fibers. However, experimental evidence is lacking. We evaluated epimuscular myofascial effects on (1) muscle belly, fiber, and mean sarcomere length and (2) sarcomere length distribution within passive fibers of the rat tibialis anterior (TA) and soleus (SO)...

The extreme ultraviolet (EUV) reflectance of amorphous tetrahedrally coordinated carbon films (ta-C) prepared by filtered cathodic vacuum arc was measured in the 30-188-nm range at near normal incidence. The measured reflectance of films grown with average ion energies in the ~70-140-eV range was significantly larger than the reflectance of a C film grown with average ion energy of ~20 eV and o...

Objective. Total antioxidant capacity in serum is determined by the total mass of antioxidant substances and the antioxidant capacity per unit mass (average activity). The purpose of this study was to develop a method to determine the mass of antioxidant substances and average activity in human serum. Methods. Specimens of serum were collected from 100 subjects each from two different age group...
