Light Scattering and Microscopic Investigations of Mesophase Transitions of Cholesteryl Myristate.

The solid state of cholesteryl myristate may exist in a negatively birefringent spherul itic form of randomly and nonrandomly correlated aggregates of crystals best characterized by an orientation correlation distance which was found to be in the order of 1 micron. Cholesteryl myristate exhibits a smectic and cholesteric mesophase both when heating from the solid and when cooling from the isotropic melt. The morphology of the smectic phase is the same upon heating and cooling. It is best described as consisting of regions having crystal orientation randomly correlated. For the cholesteric phase, however, non-randomness leads to correlated regions having definite shape. On heating to the cholesteric phase there is a transition from the solid state or the smectic phase to a cholesteric phase having disclike non-random orientation correlation. The isotropic cholosteric phase transition, occuring on cooling, on the other hand, occurs in two steps, The first is a rapid transformation to a turbid blue homeotropic state consisting of particles of sizes less than one micron, while the second is a much slower transition to a more macroscopically ordered focalconic spherulitic state. The latter transformation may be described by nucleation and growth kinetics similar to those obeyed by crystalline polymers. The process can be followed by direct microscopic observation, by the depolarized light transmission technique or\u27 by the low angle light scattering procedure. The light scattering is similar to that observed for a spherulitic polymer and is shown to arise principally from fluctuation in the orientation direction of anisotropic structures. Spherulite sizes, orientation of the optic axes, and kinetic parameters are determined. The kinetics of transformation fit the Avrami equation giving an n value of 3. The analysis of the temperature dependence of the growth and nucleation rates yields very small small interfacial energy products, δ1 δ2, of 0.1 and 0.2 erg2/cm4 for growth and nucleation respectively

Text to speech using Mel-Spectrogram with deep learning algorithms

The purpose of text to speech (TTS), sometimes called speech synthesis, is to synthesize a natural and intelligible speech for a given text. A wide range of applications uses TTS technologies in media, chatbots, and entertainment, among other fields, making it a hot topic for the research community. Recently, the progress achieved by artificial intelligence, especially in deep learning and neural networks, enables TTS to produce a high-quality synthesized speech. However, despite the success achieved, currently, available works suffer from the need for very long training and inference time, which makes it dominated by big tech companies. This paper proposes a model based on convolutional neural networks (CNN) and gated recurrent units (GRU). The proposed model can work even in low computational environments and requires low training time. The MOS achieved is 4.26, higher than the MOS performed by state-of-the-art methods

Distant Resolution of Actinic Keratosis following Cryosurgery: An Unusual Phenomenon

Early after the introduction of cryosurgery to clinical practice, there were reports of metastasis regressing after cryosurgery of a primary tumour, mainly prostate and breast cancer, suggesting a systemic immunological effect to a local reaction. Colleagues within dermatology have occasionally experienced similar systemic effects following cryosurgery. However, published reports of such cases are lacking. In this case, we report a photographed distant resolution of an actinic keratosis (AK) on 68-year-old woman’s arm following cryosurgery of another AK on the same arm

Partai Golkar Pada Masa Orde Baru Di Gorontalo Tahun 1977-1998

This article aims to find out about the New Order Golkar Party in Gorontalo. The Golkar Party was the strongest party during the Soeharto era, the Golkar party was born from an organization called the Golkar Secretariat or the Joint Secretariat of Golkar. During the Soeharto era, this political party became the government party, which every time a general election was held, it always won. In the period 1977 to 1998 elections were held in the province of Gorontalo. Likewise, Gorontalo feels the same way with other regions. The Golkar Party which at that time became the dominant party of the other two parties, namely PDI and PPP. The three parties during the New Order era that were more powerful and still stronger than the government were the Golkar party

Analysis of Performance of Permanent Magnet Generator Fluks Axial 1 Phasa with Variation Load

With the potential of low water head energy and relatively small water discharge then it takes a low round generator to be applied to the potential of existing energy. The development of Permanent Magnet Generator (PMG), being an alternative considering the pole construction of the rotor is relatively simple compared to conventional generators, so it is technically required a more number of rotor poles in the effort to lower the speed The nominal dial generator. The purpose of this research is to analyze the 1-phase axial generator performance with varied resistive loads and inductive loads. This research has 4 stages of research: 1). Study literature.  2). Carried out testing tools. 3). Measurement of data retrieval.  4). Data analysis. From this research obtained results from the tools and measurements of the data retrieval of the performance of axial generator 1 phase with inductive and resistive load Vaiasi. Load mounted 15 watts, voltage 35.10, current 0.80, RPM 2550 when load 75 Waat, Voltage 11.50, current 1.54, RPM 2220. From these results can be concluded axial generator 1 phase currents also get bigger but voltage and rpm decreases

Characterization of a de novo constitutional balanced translocation

Abstract Reciprocal balanced translocations associated with clinical features are very rare. This study reports cytogenetic and molecular cytogenetic findings in a 3-year-old patient with mild developmental retardation, slight hypotone with a de novo balanced 46, XX, t(2; 11) (q33; q23) translocation. G-banded chromosomes and FISH-Analysis were used to examine the patient's karyotype as well as her parents'. FISH-probes prepared with specific RP11-BAC clones mapped near 2q33 and 11q23 regions were used to characterize the location of the breakpoints. The FISH results revealed that one of the break points is located within the human NBEAL1-Gene locus on chromosome 2, suggesting a correlation between this gene disruption and the patient’s mild developmental retardation. 

Construction of cubic Ball surface based on biharmonic partial differentiation equation

This paper will discuss a new method of Ball surface generation from prescribed boundaries based on the partial differential operator. In particular, we focus on the construction of a bicubic Said-Ball surface using biharmonic partial differentiation equation. The main result is that the use of biharmonic Said-Ball surface would enable the overall surface to be generated and controlled based on the boundary curves rather than a set of control points. We illustrate the new method by using several graphical examples
