Linear and Nonlinear Optical Properties of Graphene Quantum Dots: A Computational Study

Due to the advantage of tunability via size, shape, doping and relatively low level of loss and high extent of spatial confinement, graphene quantum dots (GQDs) are emerging as an effective way to control light by molecular engineering. The collective excitation in GQDs shows both high energy plasmon frequency along with frequencies in the terahertz (THz) region making these systems powerful materials for photonic technologies. Here, we report a systematic study of the linear and nonlinear optical properties of large varieties of GQDs (400 systems) in size and topology utilizing the strengths of both semiempirical and first-principles methods. Our detailed study shows how the spectral shift and trends in the optical nonlinearity of GQDs depends on their structure, size and shape. Among the circular, triangular, stripe, and random shaped GQDs, we find that GQDs with inequivalent sublattice atoms always possess lower HOMO-LUMO gap, broadband absorption and high nonlinear optical coefficients. Also, we find that for majority of the GQDs with interesting linear and nonlinear optical properties have zigzag edges, although reverse is not always true. We strongly believe that our findings can act as guidelines to design GQDs in optical parametric oscillators, higher harmonic generators and optical modulators.Comment: 21 pages, 11 figures, 4 table

STUDY THE EFFICACY OF ROHITAKMUL CHURNA IN THE MANAGEMENT OF SHWETAPRADAR W.S.R. TO LEUCORRHEOA

Every woman faces varies physiological and psychological changes during this "change of life" as a part of hormonal derangement. Now a days women's health is of prime importance to get a healthy society. Woman play different roles in her life and these balances the family and keeps them nested together. It is important that she should remain healthy and proper attention should be paid towards her health. But because of their shyness and hesitation they would not discuss freely about their diseases relating to the exposable parts of the body and thus they get the diseases ultimately more and more complicated.Any deviation from natural process leads to complications like irritation in vagina due to excessive discharge which in turn causes divesting effect on marital harmony. This irritation can  be caused due to infection or pathological manifestation in the vagina. “Shwetpradar” which is identified as white discharge which is commonest in all gynecological disorder’s like vaginitis. Leucorrhoea is a white discharge from the vagina. Normally, vaginal discharge occurs in regular variations of amount and consistency during the course of the menstrual cycle. A greater than usual amount is normal in pregnancy, and  decrease is to be expected after delivery, during lactation, and after menopause.It may be physiological or pathological. Physiological excess of vaginal discharge does not require any treatment. But, the pathological conditions which necessitate treatment are those involving many infections due to Candida, Trichomonas, Gram negative, Gram positive etc. organisms. Whenever women suffer from certain pathological conditions the effective treatment is very essential. It is hoped that the research work in the field of Ayurveda will create much interest in the medical practice and for scientific application and interpretation of Ayurvedic  formulations. Rohitakmul Churna is one above them. For this study we have use Rohitakmul Churna for treating Shweatpradar

Obesity in pregnancy: maternal and perinatal outcome

Background: Obesity, the silent epidemic worldwide has reached a stage where approximately 2.3 billion adults will be overweight and more than 700 million adults will be obese by 2015, as projected by WHO. The objective of this study was to find out the incidence of the pregnancy complications due to maternal obesity and to assess the neonatal outcome.Methods: Retrospective study conducted in Cheluvamba Hospital, Mysore from September 2014 to September 2015. Subjects were categorized into 3 classes based on the BMI. Class 1:30-34.9 kg/m2, class 11:35-39.9 kg/m2, Class 111: >40 kg/m2. The maternal and perinatal outcome of the subjects evaluated in relation to body mass index.Results: A total of 56 women were included in the study, with 37 belonging to class I, 13 women class II, 6 women class III. Class III women were significantly more likely to have pre-eclampsia (83.3%, 69.2%, 27%) and post term pregnancy (50%, 38%, 16.2%) than class II and class I. The incidence of GDM (7.6%, 5.4%) and IUGR (7.6%, 2.7%) are more in class II compared to class I. Instrumental deliveries (10%, 28.5%) and LSCS (45.9%, 46.1%, 66.6%) rates increased as the BMI increased from class I to class III. Postpartum complications like PPH (5.4%, 7.6%, 33.3%) and wound gapping (7.6%, 16.6%) were on rise with increased BMI. Class III women were more likely to have macrosomic babies than class II and class III (33.3%, 15.3%, 18.9%).Conclusions: As the BMI increases pregnancy is more likely to get complicated. Interventions directed towards weight loss and prevention of excessive weight gain must begin in the pre-conception period. Obstetrical care providers must counsel their obese patients regarding the risks and complications conferred by obesity and the importance of weight loss

Improving Data Transmission Rate with Self Healing Activation Model for Intrusion Detection with Enhanced Quality of Service

Several types of attacks can easily compromise a Wireless Sensor Network (WSN). Although not all intrusions can be predicted, they may cause significant damage to the network and its nodes before being discovered. Due to its explosive growth and the infinite scope in terms of applications and processing brought about by 5G, WSN is becoming more and more deeply embedded in daily life. Security breaches, downed services, faulty hardware, and buggy software can all cripple these enormous systems. As a result, the platform becomes unmaintainable when there are a million or more interconnected devices. When it comes to network security, intrusion detection technology plays a crucial role, with its primary function being to constantly monitor the health of a network and, if any aberrant behavior is detected, to issue a timely warning to network administrators. The current network's availability and dependability are directly tied to the efficacy and timeliness of the Intrusion Detection System (IDS). An Intrusion-Tolerant system would incorporate self-healing mechanisms to restore compromised data. System attributes such as readiness for accurate service, supply identical and correct data, confidentiality, and availability are necessary for a system to merit trust. In this research, self-healing methods are considered that can detect intrusions and can remove with intellectual strategies that can make a system fully autonomous and fix any problems it encounters. In this study, a new architecture for an Intrusion Tolerant Self Healing Activation Model for Improved Data Transmission Rate (ITSHAM-IDTR) is proposed for accurate detection of intrusions and self repairing the network for better performance, which boosts the server's performance quality and enables it to mend itself without any intervention from the administrator. When compared to the existing paradigm, the proposed model performs in both self-healing and increased data transmission rates.

Evaluation of anti- inflammatory activity of aqueous extract of Mangifera indica leaves in albino rats

Background: Mangifera indica (MI) commonly known as mango belongs to the family anacardiaceae, distributed in rural and semi urban parts of India. According to Ayurveda, various medical properties are attributed to different parts of the mango tree. The purpose of the study was to evaluate anti-inflammatory activity of aqueous extract of Mangifera indica leaves.Methods: Aqueous extract of Mangifera indica leaves was prepared and tested for anti-inflammatory activity in albino rats weighing 200-250 gm. The in vivo anti-inflammatory activity was evaluated by using Acute (carrageenan induced paw edema) and chronic (Formalin induced paw edema) animal models. Rats were divided into 4 groups, 6 rats in each group. Group I (control) received 0.1 ml 4% gum acacia suspension. Group II and Group III received Mangifera indica extract at doses of 200 mg/kg and 400 mg/kg body weight. Group IV (standard) received diclofenac 10 mg/kg body weight. All the drugs were administered orally. Anti-inflammatory activity was expressed as percentage inhibition of paw edema.Results: The percentage inhibition in carrageenan induced paw edema with 200 mg/kg and 400 mg/kg Mangifera indica extract was 44.8% and 53% and in formalin induced paw edema was 47.5% and 64.4% respectively. The two doses of Mangifera indica extract showed significant anti-inflammatory action (p<0.001) in both models.Conclusions: Aqueous extract of Mangifera indica leaves showed significant dose dependent anti-inflammatory activity

Music and Health

Music therapy is the use of intervention to accomplish individual goals within a therapeutic relationship by a professional who has completed an approved music therapy programme. Music has several physiological effects including positive effects on mood, a reduction of anxiety, stress and a lowering of blood pressure. There are several types of music therapy. Music therapy procedures are structured as either receptive or active. Music therapy methods include music recreation, improvisation, composition, listening and receptive experience. In modern health care, music has several applications in the perioperative setting, neurology, family medicine, paediatrics, obstetrics, interventional procedures, the critical care unit, pain management, palliative care and cancer. Though it has some limitations, there is ample scientific evidence to support the beneficial use of music therapy as a low-cost therapy with no side effect in various clinical situations in current health care settings. This article describes the various applications of music in modern health care.
