В июле–августе 2009, 2010, 2012 гг. исследован состав и структура зоопланктона в системе \nХарбейских озер Большеземельской тундры. Обнаружено 87 видов и форм, из которых более \nполовины коловратки (Rotifera). Планктонная фауна обследованных озер обычна для южных \nтундр и представлена азональными таксонами. Зоопланк…
In this study, new compositions of Tsai-type 1/1 quasicrystal approximants Gd(14)Au(70)Si(16), Gd(14)Au(67)Ge(19), Tb(14)Au(70)Si(16) and Yb(16)Au(65)Ge(19)are synthesized using both self-flux and arc-melting-annealing techniques. Both syntheses routes resulted single phase samples. The crystal structures of the compo…
In this article, a nanoporous chitosan polymer membrane was successfully produced and applied as microdialysis membrane for in vitro sampling of biomolecules. With the use of nanoparticle leaching ...
This paper studies the effect of nitric oxide (NO) on the onset of knock in a cooperative fuel research (CFR) engine. The experiments are conducted at both the standard knock intensity (SKI) condition for research octane number (RON) tests, as well as at a richer operating condition of a similar knock intensity but a…
A unialgal culture of a Pseudo-nitzschia species dominant in the plankton of Algoa Bay in the spring of 2012 was established by isolation of clonal chains of cells. Identification of the species as Pseudo-nitzschia multiseries was based on frustule morphometrics provided by light and scanning electron microscopy, and…
Over past the decades there has been a growing interest in the isolation of cellulose due to its high demand in paper industries, food industries, pharmaceutical and textiles. In this project, cellulose from sawdust will be isolated and characterized using FTIR and SEM. The cellulose from sawdust was isolated through…
This dissertation presents an experimental investigation on the growth and characterization of the quasi-binary Ga2Te3-Ga2Se3 semiconductor alloy. Single crystal Ga2(Se1-x<\sub>Tex)3 specimens were grown via modified Bridgman methods for x = 0.60, 0.67, 0.8, 0.9, and 1.0. Preliminary structural characterization via po…
Ketoprofen masuk ke dalam BCS kelas II yang memiliki kelarutan rendah namun memiliki permeabilitas tinggi, sehingga ketoprofen dibuat dalam sediaan SNEDDS menggunakan Virgin Coconut Oil (VCO) sebagai fase minyak, kombinasi surfaktan tween 80 dan tween 20, dan propilenglikol sebagai ko-surfaktan, kemudian akan dievalua…
Photovoltaic cells or commonly known as solar cells offer a promising alternative source of clean energy to address dramatically growing needs for electricity. Dye-sensitized solar cells (OSSCs) have attracted much attention in recent years for the lower fabrication cost \ncoupled with outstanding photovoltaic convers…
In this work, we present evidence on the suitability of spin probes to report on the thermal treatment of bovine serum albumin (BSA), in the temperature range 293–343 K, and indirectly monitor the release of sodium dodecyl sulfate (SDS) from its complex with BSA using a covalent gel with β-cyclodextrin (β-CD) in the n…
The healing of full thickness wounds such as burn wounds remains complicated by hypertrophic scar formation and contraction. The standard treatment is transplantation with autologous split thickness skin grafts. For extensive burns, these grafts are widely meshed due to limited donor sites, which often results in a po…
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space grou…
The tension–tension fatigue behaviours of quasi-isotropic woven-ply thermoplastic (Polyphenylene Sulphide – PPS) and thermosetting (Epoxy)-based laminates are discussed in this paper. The service temperature of these materials is such that Tg|C/PPS<T<Tg|Epoxy, and matrix ductility is expected to reflect on the fatigue…
Background One of the important problems in the development of oil fields is the corrosion protection of the pipelines. Steel oil and gas pipelines without an internal protective coating due to the strong corrosiveness of well fluids have low lifetime. The life of pipelines could be increased in different ways, one of…
Polycrystalline La0.5Sr0.5CoO3 (LSCO) film is prepared on Pt/Ti/SiO2/Si substrates by pulsed laser deposition in order to explore the resistive switching behavior of the Ag/LSCO/Pt structure. It is found that the oxygen stoichiometric LSCO (LSCO-2) structure does not possess distinct rectifying behavior, while the oxy…
Three types of hydrazone ligand were synthesized by direct condensation reaction by using (99%) ethanol as the standard solvent. Ligand (1) was synthesized by direct reaction of methyl-2-pyridyl ketone with isonicotinic acid hydrazide. Ligand (2) was synthesized by direct reaction of vanilin with isonicotinic acid hyd…
This paper presents the results of investigations of the melting diagrams for the systems durene/SbCl₃, pentamethylbenzene/SbCl₃, hexamethylbenzene/SbCl₃, diphenyl/SbCl₃, naphthalene/SbCl₃, 2,3-dimethylnaphthalene/SbCl₃, phenanthrene/SbCl₃ and anthracene/SbCl₃; in all cases solid complexes with the composition ArH · 2…
We employ a scanning nitrogen-vacancy-center microscope to perform stray field imaging of bubble magnetic domains in a perpendicularly magnetized Pt/Co/AlOx trilayer with 6 A of Co. The stray field created by the domain walls is quantitatively mapped with few-nanometer spatial resolution, with a probe-sample distance…
An investigation has been carried out to reduce the deformation behavior of polyethylene (PE) woven geotextile fabric by making PE fabric-glass yarn composite structure using stitching and laminating. The results showed that reinforcement significantly reduced the creep and IED as long as the tensile stress is lower t…
