The cholesteric liquid-crystal poly[oxycarbonyl-1,4-phenylene-oxy-1,4 terephthaloyl-oxy-1,4-phenylenecarbonyloxy(
1,2-dodecane)] [C34H36O8]n, named PTOBDME, synthesized by polycondensation reaction from
equimolar quantities of TOBC and the racemic mixture of glycol (R-S-1,2 dodecanediol), exhibits unexpected
optical activity and chiral morphology. The structure of racemic-PTOBDME, under different polymerization
kinetics conditions, is analyzed by conventional NMR techniques and compared with those of polymer
enantiomers R-PTOBDME and S-PTOBDME obtained starting R(+)1,2 and S(-)1,2-dodecanediol respectively.
Molecular models based on the NMR signals intensities are proposed. The optical activity of racemic-
PTOBDME is evaluated by measuring the ORD values during kinetics study, and compared to the chiral
polymers. Each enantiomeric polymer seems to present the same stereoregular head-tail, isotactic structure than
the racemic, which we explain by the higher reactivity of the primary hydroxyl than the secondary one in the
glycol through polycondensation. For each enantiomer, two independent sets of signals were observed by NMR,
explained as two diastereomeric helical conformers: gg and gt, related with two possible staggered
conformations, along the copolymer backbone. Chirality in racemic-PTOBDME is proposed to be due to the
kinetic resolution of a preferable helical diastereomer, such as Sgt, with respect to the possible four forms, while
the R/S ratio of asymmetric carbon atoms remained 50:50. Chiral amplification is observed in R-PTOBDME and
S-PTOBDME due to a helical screw sense excess. Optimum yield was obtained for racemic PTOBDME, after
120 minutes polycondensated and decanted in toluene for 24 hours. Two weeks later a second fraction
precipitated from the toluene mother liquor with 67.6% chiral excess. After eight months and two weeks a third
fraction precipitated with 85.2% chiral excess.

Preparation of Mixed Phase (Anatase/Rutile) TiO2 Nanopowder by Simple Sol Gel...IJLT EMAS
TiO2 nanopowder having both anatase and rutile
phases was prepared by a simple procedure using sol-gel method.
Titanium isopropoxide was used as a titania source and mixed
with methanol and TiO2 nanopowder was obtained after
annealing at 6000C for 1 hour in air. The specimens made from
this powder were characterized by X-ray diffraction (XRD),
Thermogravimetric analyzer (TGA) and Transmission electron
microscopy (TEM). XRD studies revealed the presence of both
anatase and rutile phases with an average crystallite size of 35 ±
5 nm. No significant weight loss up to 7000 C was observed by
TGA curve which indicates that TiO2 nanopowder is thermally
stable. TEM revealed the presence of a number of crystalline
grains in a structured matrix and selected electron diffraction
pattern showed different arrangement of diffracted rings which
confirms a phase evolution of crystalline grains of TiO2
(anatase/rutile) due to thermal annealing. Mixed phase
(anatase/rutile) TiO2 nanopowder has been reported [1], [2] to
exhibit improved photocatalytic and gas sensing properties. It is
proposed to study the gas sensing behavior of these specimens
during our research investigations on TiO2 nanopowder.

Study of characterization of (peo+kclo4) polymer electrolyte systemeSAT Journals
Abstract Solid state polymer electrolytes have been prepared by using poly (ethylene oxide) (PEO) and KClO4 salt in the Wt% ratios of (90:10), (80:20) and (70:30) by solution – casting technique by using methanol (water-free) as solvent. The complexation of pure PEO with KClO4 salts has been extensively studied using IR studies. In the Differential Scanning Calorimetry (DSC) curves it observed that, pure PEO melting temperature (Tm) slight shift towards lower temperature is due to the addition of KClO4 salt to the polymer. XRD data for these films clearly confirm the complexation between the KClO4 salt and the polymer PEO. The d-values calculated from the X-ray diffraction of pure PEO and various compositions of KClO4 complexed films are clearly indicate the complexation of PEO and KClO4. Keywords: Polymer electrolytes, IR studies, differential scanning calorimetry, X-ray diffraction.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
