Formulation Development of Haritaki Cream by Using 2 (square ) Factorial Design

Creams, in general, are versatile skincare formulations that provide a balance of water and oil to deliver hydration and nutrients to the skin. Eye creams are a category of skincare products specifically designed for the sensitive and delicate skin around the eyes. The skin in this area is thinner and more prone to issues such as fine lines, wrinkles, puffiness, and dark circles. Eye creams are formulated to be lightweight and easily absorbed, and they typically contain ingredients tailored to address these specific concerns. Common ingredients in eye creams include hydrating agents, anti-aging compounds, brightening ingredients, and sometimes caffeine or other ingredients to reduce puffiness. From the developed formulation of haritaki cream we concluded that it can be used for dark circle. It contains various other excipients like potato starch, alovera, methyl and propyl paraben etc. it does not only reduce dark circles but also glows skin and reduces skin damage. As it causes no irritation it is better than allopathic cream. As it had passed all the evaluation parameters like pH, washability, phase separation, irritations, edema, spread ability etc.

Adjusting of the chemical coordination environment of the active constituent to enhance wide‐temperature NH3‐SCR activity of Ce, Cu, and La modified TNU‐9

A series of Ce, Cu, and La modified TNU‐9 zeolite catalysts were synthesized by altering ion exchange sequence and calcinations sequence, and the relationship between the chemical coordination environment of the active ingredients and the catalytic activity in the selective catalytic reduction of NOx using NH3 as reductant (NH3‐SCR) was revealed. The results showed that within the temperature window (150–450°C), the catalyst (Cs‐CL/T9) prepared by exchange copper ion, followed by roasting, then followed by simultaneous exchange of cerium and lanthanum ion had excellent wide‐temperature NH3‐SCR activity. Because after roasting, Cu2+ in the framework of TNU‐9 could migrate under the high temperature to result in the stable structure, thereby reducing steric hindrance ions and exchanging more cerium and lanthanum ions. The increase of cerium ion content can produce more oxygen vacancies, so that NO is oxidized to NO2. Furthermore, electron paramagnetic resonance (EPR) results exhibits that there are Cu2+ active site in Cs‐CL/T9, leading to the excellent NH3‐SCR performance. In addition, altering ion exchange sequence and calcinations sequence increase the number of acidic sites and the redox ability etc.

Association of Spastic Paraplegia and Short Stature in Patients of Autosomal Recessive Intellectual Disability

Background: Intellectual Disability “ID” is a genetic disorder, which lead to arrested or incomplete development of the brain. It is the limitation of cognitive skills impairment and decline ability of a person in learning process. ID is the most common health problem in worldwide. These patients have decline intellectual functions and at least limitation in their two or more adoptive skills such as reading, writing abilities, social interactions, Behavioral habits, self-care, communication ability etc. The time period for the diagnosis of ID is the onset of disease before the eighteen years of age. Spastic Paraplegia and short stature is a general terminology using for a group of an uncommon inherited diseases that cause stiffness and weakness in the lower limbs muscles. Gradually its symptoms get worse with the passing of time. It's also called as familial spastic paraparesis or Strümpell-Lorrain syndrome. SP is classified clinically as “complicated" (syndromic) or "uncomplicated" (nonsyndromic) Spastic Paraplegia. Methods: This study was started in March 2014 to Aug 2015. The criteria for the selection of families were consanguineous families with two or more than two ID patients. The patients were examined, interviewed one by one in friendly atmosphere. Then the blood samples were taken by aseptic method. Blood samples were processed in laboratory. DNA extraction and PCR was done. After that Exome sequencing was used to find the pathogenic variants. The data was analyzed by CATCH. Sanger Sequencing was applied to see the segregation. Results: In ID-family1 the variant of AP4B1 was segregated with the disease phenotype. These ID patients have short stature and Spastic Paraplegia. Mutation in AP4B1 is known to cause intellectual disability. In ID-family2 the variants of WDR62, EML2 and KCNK6 were co-segregated with disease phenotype. But only mutations in WDR62 are known to cause intellectual disability. ID family2 also identified as short stature. In ID-family3 Exome sequencing data reveal no putative variants. Conclusion: The present study was conducted in three consanguineous families for the determination of the responsible genes for intellectual disability. Exome sequencing revealed putative mutations in AP4B1 and WDR62 in two out of three families. In third family we could not locate any putative mutation.

Effect of Deha Prakruti on Intelligence - An Appraisal

Ayurveda lays great emphasis on the concept of Prakruti (body constitution) in the diagnosis, prognosis and treatment. Panchamahabhoota (five basic elements of the universe) in different permutation and combination form Tridosha (three humors of the body). Prakruti is formed depending on the predominance of any one or two or three Dosha at the time of conception. Prakruti is of two types: Dosha Prakruti or Deha Prakruti and Gunamayi Prakruti or Manasa Prakruti. Deha Prakruti is of 7 types. Vataja, Pittaja, Sleshmaja, Samsargaja [combination of two Dosha] i.e., Vata-Pitta, Pitta-Sleshma, Sleshma-Vata and Sannipataja [combination of three Dosha] i.e., Vata-Pitta-Sleshma. The person of each Prakruti is mentioned to be endowed with different characteristic features which includes physical and psychological features, abilities etc. Medha (intelligence), Smruti (memory) are psychological factors differentiating one person from other with respect to ability to perform any task. Prakruti is the deciding factor of various psychological characters including Medha. This article aims at studying the effect of Deha Prakruti on intelligence.

Caregivers’ burden among parents of children with Cerebral Palsy

Introduction: Caregivers help a person in those actions which cannot be performed by an individual independently; a person’s personal needs, environmental barriers that hinders an individual’s abilities etc. This ultimately puts an increased burden on the caregiver. This study was conducted to determine the levels of caregivers’ burden among the parents of children with cerebral palsy. Material & Methods: A cross-sectional survey was conducted on 298 parents of children with cerebral palsy. Non-probability convenience sampling technique was used to collect data from the parents coming to the National Institute of Rehabilitation Medicine, Islamabad. The parents of children with cerebral palsy who were having auditory, cognitive or visual impairment were excluded from this study. Demographic information form and Caregiver Burden Inventory were used for the data collection. The data was analysed through IBM SPSS version 21 and results were presented in the form of frequency, percentages and mean ± sd with p-value wherever needed. Results: the result of this study showed a greater need for respite and other services for caregivers of children with cerebral palsy. The overall Caregiver Burden Inventory score was 45.19 ± 11.9. Out of the total included participants, 163 (54.33%) participants sometimes needed relief, 116 (36.67%) needed frequent need for relief and other services while 19 (6.33%) of the included parents rarely needed relief and other services. Conclusion: Majority of the caregivers of children with cerebral palsy needed relief and other services (compromise the growth, physical and emotional health and social relationship) to manage caregivers’ burden.

Low-frequency microwave absorption of MOF-derived Co/CoO/SrCO3@C composites

Considering the fast progress of microwave technology and precise electronic devices, great efforts of developing electromagnetic wave absorption materials have been devoted to conquer electromagnetic interference and radiation etc. Herein, a series of MOF-derived Co/CoO/SrCO3@C composites have been obtained via facile two-stage strategy, and the influence of solvent ratio on the final low-frequency electromagnetic wave absorbing performance of as-prepared hybrids has been investigated as well. The composite prepared with DMF/EG ratio of 120mL/80 mL possesses the best microwave absorption properties i.e. the maximal RL can reach −39.51 dB at 0.41 GHz with EAB of 0.12–1.26 GHz for 2 mm thickness, and its largest EAB can be observed at only 1 mm for a board range of 0.45–3 GHz, which is due to the interlaced structure of NPs and hollow nanotubes, thus it can attenuate incident microwave via strong conduction loss, magnetic wastage and opportune dielectric dissipation ability etc. This MOF-derived absorbent could be applied as practical candidate for efficient low-frequency electromagnetic wave absorbing indeed.

A Sensitive-Information Hiding Treatment in Quick-Response Codes Based on Error-Correcting Framework

Quick Responding codes, namely QR codes, are widely used in various communication applications and electronic transactions such as electronic payments and information integrations, since they provide excellent characteristics such as large data capacity, widely coding domain, and stronger error correction ability etc. However, as the QR code is transmitted on public channel and can be scanned by any QR reader, one can obtain the data from the encoded QR code. Simultaneously, the encoding and decoding algorithms are public, the sensitive data such as paying account and password will be revealed to the QR reader, which might incubate the risk of privacy leakage. For solving this problem, this paper proposes a novel approach to protect the private data in QR code. In our method, the secret information is embedded in the random position of a QR code matrix by utilizing an error-correcting mechanism, and only authorized user in possession of required keys will be able to retrieve and recover this secret data embedded and hidden in the QR code. The user without the secret key can only decode public information from the QR code. Although our hiding scheme will decrease the rate of error-correctness of QR decoding, we indicate that the analysis shows that scheme is effect om practical applications. Compared with related schemes, the proposed scheme provides higher security that is less likely to attract the attention of potential attackers.

Student Classification Based on Cognitive Abilities and Predicting Learning Performances using Machine Learning Models

Education is the vital parameter of the country for development in divergent areas like cultivation, economic, political, health and so on. Any educational Institute’s (universities, colleges, schools) main goal is to increase the student’s learning capabilities and their skills for their full contribution towards the society. In these days, “student’s learning process and skill development” research topic requires much needed attention for the betterment of the society. The student’s performance depends on his/her learning ability and is influenced by many factors. In this paper, we analyze the different categories of student’s leanings that are very fast, fast, moderate and slow. For this, we conducted the training and tests for attributes like ability, knowledge level, reasoning and core subject abilities for the 313 engineering students in AITAM, Tekkali, affiliated to JNTUK, India from 2017 to 2019. We gathered information about personal, academic, cognitive level and demographic data of students. In this experiment, we are conducting statistical analysis as well as classification of students into 4 types of learners and applying the different Machine Learning (ML) techniques and choose the best ML algorithm for predicting students learning rates. This leads to conducting the remedial classes with new teaching methods for moderate and slow leaning students. The proposed paper accommodates the individual differences of the learners in terms of knowledge level, learning preferences, cognitive abilities etc. For this, we apply 5 ML algorithms that are Naive Bayes, classification Trees (CTs), k-NN, C4.5 and SVM. As per ML analysis, the k-Nearest Neighborhood (k-NN) algorithm is more efficient than other algorithms where the accuracy and prediction values are nearer to 100%.

Experimental Study on Seismic Behavior of K-type Eccentrically Braced Steel Frame with Semi-rigid Joints

In order to study how different connection types and floor height affect the seismic behavior of eccentrically braced steel frame, there has been processing 4 pseudo-static tests for eccentrically-braced steel frame, including two one-layer specimen and two three-layer specimen. The seismic behavior of the specimen has been analyzed according to hysteresis curve, carrying capacity, stiffness degeneration, ductility, and energy dissipation ability etc. The experiments’ results show that the connection types have greater impact on seismic behavior, adopting specimen destruction model of high-strength bolts connection as beam segment end-plate weld or web fracture. The rest of components do not appear significant yielding deformation and crack, which caters for post-earthquake restoration and replacement of energy dissipation beam segment. The carrying capacity of high-strength bolts connection specimen is slightly lower than welded connection specimen, but the ductility of the former is far beyond the welded specimen. Because of the slippage between components, hysteresis curves of bolts-connected eccentric braced steel frame structure appear to have pinned phenomenon with various degrees.

Nitrogen doped waste tea residue derived carbon dots for selective quantification of tetracycline in urine and pharmaceutical samples and yeast cell imaging application

In this work, waste tea residue, abundantly accessible, is utilized for synthesis of fluorescent carbon dots (CDs) by a simple, low cost and one step chemical oxidation method. The optical properties, surface functionality and particle size of CDs were ascertained by various techniques. The CDs exhibited excellent water solubility, optical properties, bioimaging ability etc. The fluorescence intensity of the CDs was diminished gradually with increasing concentrations of tetracycline drug owing to the inner filter effect (IFE) phenomenon. The developed fluorescent probe displayed a better linear range, excellent detection limit and interference free response to the tetracycline. This resulted in quantification of tetracycline in real sample which achieved almost 99% recoveries indicated excellent practical potential. Moreover, the CDs were used as fluorescent label for multicolour imaging of yeast cells which could open the doors for further research in biological fields.

Development of sulfide-doped Graphene/Fe3O4 absorber with wide band electromagnetic absorption performance

Graphene has been confirmed as an ideal lightweight and high-performance electromagnetic (EM) absorber if used to deal with increasingly electromagnetic interference issue. However, the actual EM absorption performance of graphene is not desirable in a thin thickness which is due to poor impedance matching behavior and single conductive loss form. To overcome this difficulty, this research employed S doping and magnetic Fe3O4 nanoparticles loading strategies to boost EM attenuation ability by introduction of various EM loss forms, e.g. dipolar, interface, and magnetic loss ability etc. Besides, the impedance matching ability of SGN/Fe3O4 has significant improved as compared to pure graphene, primarily owing to the sharply decrease of relative complex permittivity (εr) values. The as-prepared S-doped graphene/Fe3O4 (denote as SGN/Fe3O4) absorber shows excellent wideband electromagnetic absorption property at a thin thickness of 2.0 mm which the frequency width with a reflection loss < -10 dB reach 5.3 GHz.

A data-driven online ADP control method for nonlinear system based on policy iteration and nonlinear MIMO decoupling ADRC

Abstract The action-critic approximate dynamic programming (ADP) depends on its network structure and training algorithm. Since there are some inherent shortcomings of the neural network, this paper proposes a data-driven nonlinear online ADP control method without the neural network. Firstly, a multi-input multi-output (MIMO) policy iteration method is utilized for the proposed ADP. For its policy evaluation, the cost function is approximated with a quadratic function and least square method; for its policy improvement, the optimal control is approximated by solving the quadratic function linearly. In this way, an optimal control equation in form of variable coefficients and system states is deduced. Secondly, a nonlinear MIMO decoupling Active Disturbance Rejection Control method is used to obtain the variable coefficients in real time, which endows the ADP method with a nonlinear performance during its policy improvement. Once the variable coefficients are determined, the data-driven nonlinear ADP control method is deduced. Finally, the examples of an under-actuated nonlinear system and a real application are taken to demonstrate the optimal control effect. Compared with some published methods and their simulation, this method and its simulation excel in the method of policy improvement, nonlinear ability and control performance etc. Thus, the proposed method explores a new way to the ADP, and overcomes the shortcomings of the neural-network-based ADP. Since it enables to work like a PID controller and does not require data collecting, training or extra learning, this proposed ADP is a real data-driven nonlinear online optimal control method.

Evaluation of anion chain length impact on aqueous two phase systems formed by carboxylate anion functionalized ionic liquids

Abstract Aqueous biphasic systems (ABS) based on ionic liquids (ILs) are considered as promising separation and extraction media for replacing conventional extraction systems consisting of volatile organic solvents. In the present work, set of ILs consisting of tetrabutylammonium cation and carboxylate anions were synthesised and studied for their ability to form ABS in presence of strong salting-out agent K3PO4 at 298.15 K and atmospheric pressure. The influence of alkyl chain length of ILs’ anions on the phase splitting ability has been systematically investigated. Experimentally determined binodal curve data has been fitted to Merchuk’s equation and corresponding fitting parameters have also been determined. Further, selected ternary systems have been analysed for their extraction efficiencies for an amino acid, Tryptophan. Solvatochromic parameters of aqueous solutions of ILs have been determined to further scrutinize their influence on extraction efficiencies of studied ABS. The results indicated that phase behaviour and extraction efficiencies are governed by multiple factors prevailing at microscopic level like hydrophobicity, hydrogen bond accepting ability etc. The combination of suitable cation and anion entities of ILs, in turn, decides the dominant physical phenomenon and consequent phase behaviour and extraction aptitudes. In addition, this work addresses the effect of temperature on ABS formation and temperature dependence similar to that of ABS consisting of polymers and inorganic salts have been observed. This work gives insights into multifaceted effects of longer alkyl chains of IL’s anion on phase behaviour and extraction aptitudes of IL based ABS.

CONTEMPORARY VIEWS ON THE TERM ‘DISCOURSE’ IN PSYCHOLOGICAL STUDIES

Various branches of science that study homo loquens, а talking man, have made an important contribution to the development of the term ‘discourse’. It is obvious that most definitions have much in common. Firstly, discourse is realized in speech; secondly, it is formed in a wide communicative context as a result of interpersonal communication and interactions between people and society; and finally, discourse has significant impact on social and personal representations and can establish group norms. The paper discusses different approaches to discourse studies, including speech act theory, conversational analysis, discourse analysis, social and cognitive psychology. Special attention is paid to Intent-analysis which considers the basis of discourse as a hierarchy of its speech intentions and their different psychological determinants. These include interpersonal relationships, personality traits, social statuses, roles and the problems speakers solve in the communication process. Several terms related to discourse are given: discoursive practice, discoursive thinking, discoursive abilities etc. The urgent issues of discourse research such as the typology of discourses, the psychological impact and interpersonal interaction mechanisms connected to the various fields of the current reality are presented.
