Studying the Infrared Spectroscopy and Structural Properties of Compounds Fluoride that Blotched by in
In doped calcium fluoride transparent conducting powder were prepared by solid-state reaction method. Structural properties of the samples were investigated as a function of various In-doping levels (x=0.00-0.01-0.02-0.03). The results of x-ray diffraction have shown that the samples are polycrystalline structure in cubic phase and show presence (111), (220), (311), (400) planes in pure CaF2 sample and the preferred orientation is (220) for pure CaF2 and we have peaks correspond (101), (112), (200), (202) for In for all samples and the preferred orientation is (112) for In for all samples. The average of crystallite size is within the range [2.976-0.845nm] for all samples. The relative intensities, distance between crystalline planes (d), crystallite size (D) and lattice parameters (a) were determined. Measuring the infrared spectrum of pure Calcium fluoride, it is found that there are six vibratory frequencies, namely: (3444.52 - 1517.59 - 1138.40 - 876.40 - 639.93 - 436.29) cm- 1 and six vibratory frequencies for indium doped calcium fluoride at 3wt%. (3441.94 - 1516.77 - 1138.44 - 876.55 - 642.09 -436.44) cm- 1 The study showed that the absorbance values, the absorption coefficient, the refractive index and the optical length were in the indium doped sample by 3wt% greater than that of the pure Calcium fluoride compound and are respectively: α=14.163 cm-1 n=1.767.
The Effect of the Morphology Optimization of Precursor with Different Nickel Content on the Performance of Lithium-Ion Battery Cathode Materials
Increasing the nickel content in the layered LiNixCoyMnzO2 (x + y + z = 1), the most promising cathode materials for lithium ion batteries (LIBs), has been a dominant strategy to increase their energy density. In this study, we report the control on the primary particle morphology of precursors with different nickel contents, e.g. Ni0.5Co0.2Mn0.3(OH)2 Ni0.6Co0.2Mn0.2(OH)2 and Ni0.8Co0.1Mn0.1(OH)2 by adjusting the preparation process. The scanning electron microscopy (SEM) images demonstrate that by decreasing the pH value and increasing the ammonia concentration, the order of precursors with different nickel contents increases, resulting in gradually directional and orderly stack or interlaced arrangement in the primary particles. With the increase of nickel content, the precursor changes from nano-sheet stacking like plug-in
stereoscopic spheres to nano-needle interweaving like wool balls, all of which tend to grow in the direction of [001].

Prenatal Diagnosis of Hydranencephaly in a Newborn of Psychic Mother with Olanzapine and Paroxetine Exposure During The Pregnancy
Hydranencephaly is an extremely rare congenital anomaly of the central nervous system, characterized by the almost total
absence of the bilateral cerebral hemispheres and replaced by cerebrospinal fluid. Almost all cases are sporadic with an
incidence of less than 1 per 10,000 births and a very poor prognosis. The exact main cause is still unknown, but
hydranencephaly is usually found to develop secondarily to the occlusion of cerebral arteries above the supraclinoid level.
We report the case of a full-term female infant with hydranencephaly diagnosed at 28 weeks of gestation by routine
antenatal intrauterine ultrasonograph

Machine Learning Prediction of Response towards Anti-VEGF Injections in Patients with DME: Prediction of Post-Injection CST
Diabetic macular edema (DME) has become one of the most potential complications that results in loss of vision in patients with
diabetic retinopathy. Treatment outcomes that have been predicted directly with advent of machine learning (ML) methods after
the initial anti-vascular endothelial growth factor (anti-VEGF) injection, has become extremely vital in the management of DME.
Purpose: The aim of this study is to analyze the efficiency of the ML regression models which were developed and validated to predict the possible post-injection central subfield thickness (CST) value and distant vision best corrected visual acuity (DV BCVA)
in eyes with DME before the anti-VEGF injection is administered at either treatment initiation or during treatment monitoring.
Methods: This retrospective study was conducted in Medical Research Foundation, Chennai, India from January 2010 to
December 2020. The model development emphasized on an ensemble ML system consisting of four ML models that were
developed and trained independently using the clinical parameters to predict the post injection CST value. The dataset
consisting of 906 patients with total of 1874 samples [Optical coherence tomography (OCT) images and clinical parameters] were divided into trained and test set, and the model was validated on test dataset. The predicted CST values was then
compared against the respective sample’s post injection actual CST value. The comparative results were measured in terms
of Correlation Coefficient and Mean Absolute Relative Error (MARE).
Results: On evaluation, we found that Support Vector Regression (SVR) with linear kernel performed best among the
other models with four different scenarios in term of both CST and DVBCVA prediction with correlation coefficient of
0.65, 0.73, 0.75, 0.85 and 0.83, 0.87, 0.89 and 0.92 respectively.
Anodizing for Design and Function
Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.
Recent Developments in Human Odor Detection Technologies

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath
The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.

polyester, rayon and wool.
The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films
The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
