Chiral plasma instability and primordial Gravitational wave

It is known that cosmic magnetic field, if present, can generate anisotropic stress in the plasma and hence, can act as a source of gravitational waves. These cosmic magnetic fields can be generated at very high temperature, much above electroweak scale, due to the gravitational anomaly in presence of the chiral asymmetry. The chiral asymmetry leads to instability in the plasma which ultimately leads to the generation of magnetic fields. In this article, we discuss the generation of gravitational waves, during the period of instability, in the chiral plasma sourced by the magnetic field created due to the gravitational anomaly. We have shown that such gravitational wave will have a unique spectrum. Moreover, depending on the temperature of the universe at the time of its generation, such gravitational waves can have a wide range of frequencies. We also estimate the amplitude and frequency of the gravitational waves and delineate the possibility of its detection by future experiments like eLISA.Comment: 8 pages, 2 figure

Scientific applicability in day-to-day practice on Granthokta Sutika Paricharya

Being a mother is most challenging and most rewarding position a woman ever holds, so motherhood is wonderful at the same time its hardest phase for woman. Giving birth to a new life is a beautiful moment a women will cherish forever. But after the delivery, mothers body encounters many physical and psychological changes which may lead to the generalized weakness and backache etc., if proper postnatal care is not taken. Mother needs to recover and heal from the physical and emotional distress experienced during the delivery. So, proper care in postnatal period is essential. Ayurveda classics emphasize on both prenatal and postnatal care of the mother. There is detailed description of postnatal period and care known as Sutika Kala and Paricharaya respectively. After the childbirth when placenta is expelled out then women is termed as Sutika[1] and Paricharya means following the diet, regimen and medicines (Aahara, Vihara and Aushadha) during the Sutika Kala (postnatal period). According to Acharyas, Mithyaachrana during Sutika Kala may result in incurable disease, so extreme care must be taken during this period.[2] The main prospective of the Sutika Paricharya is to retrieve the strength and vitality of the mother’s body same as non-pregnant state along with stabilization of the physiological and psychological health. It also improves the quality and quantity of breast milk of mother. In present time due to changing lifestyles and food habits Sutika Paricharya can be a solution to many problems faced due to Mithyaachrana during the Sutika Kala

A case study on the management of Garbhini Chardi w.s.r. to Emesis Gravidarum

Pregnancy is regarded as the most delicate time in a women life. Maternal physiology is under continuous adaption throughout the pregnancy. One such bothersome side effect of such physiological changes occurring during pregnancy is Emesis Gravidarum which has significant impact on pregnant women life, including everyday functioning and general wellbeing. As Chardi is considered a Vyakta Garbha Lakshana it is not associated with much harm to growing fetus or mother and is therefore considered a physiological disorder; however, when it occurs frequently it develops into Hyperemesis Gravidarum, a pathological condition that require early intervention to prevent symptoms such as extreme dehydration, exhaustion weight loss, congenital problems in fetus and early labor etc. that could harm the developing fetus. In this study effort have been undertaken to evaluate the efficacy of Eladi Choorna in Garbhini Chardi

Concept of Artava and its applied aspect in Stree Roga

Women represent the cornerstone of a family’s overall health. Healthy women, Healthy world embodies that women are custodians of family health; they play a critical role in maintaining the health and overall wellbeing of community. In Ayurveda word “Artava” denotes menstrual blood.  Artava is related to 2 seasons i.e., it may be due to presence of Ritukala (ovulation period) and Rajakal (menstruation period) in women. Human body is controlled by the three energies called Tridoshas - Vata, Pitta and Kapha which are characterized under seven Dhatus. These Dhatus have Updhatus also. Artava (menstrual blood) is one of the Updhatus of Rasa Dhatu.[1] The specific characteristics of menstrual blood with its physiological and pathological variation described in Ayurveda classics as Shudhartava and Artavdhusti respectively help in identifying the hormonal status of women. Shudhartava plays crucial role in maintaining women’s healthy reproductive life. When Artava is not quite same as highlights of Shudhartava mentioned in classics then there may be Artavdushti or menstrual abnormalities like dysmenorrhoea, menorrhagia, amenorrhoea etc uterine disorders like endometriosis, adenomyosis, uterine fibroid, etc which may be cause of infertility. Ayurveda classics explains about colour, texture, specific smell, amount and other associated features like type of pain in various Artavdushti. So, only by observing menstrual blood variation we can find out the disease associated with it. Thus, study of Artava and Artavdhusti plays a very significant role in diagnosis of pathological disorders related with female reproductive system.&nbsp

Role of Mundi Taila on Anovulatory Factor - A Case Study

Infertility is defined as inability to conceive with minimum one year of regular unprotected coitus. In Ayurveda, Vandyatwa is a condition where a female fails to conceive and unable to continue pregnancy. Bheda and Chikitsa of Vandyatwa is mentioned in Ayurvedic text. There may be many of reasons for this condition to cause. Anovulation factor is described as a cause of infertility. Ovulation is under the control of Vata. In current study, an effort has been made to study the effect of Uttarbasti on anovulation. A 27 years of Patient of female infertility having anovulatory factor being diagnosed by TVS for 2 consecutive cycles. Patient is administered the Uttarbasti through Mundi Taila

Viscosity in cosmic fluids

The effective theory of large-scale structure formation based on $\Lambda$CDM paradigm predicts finite dissipative effects in the resulting fluid equations. In this work, we study how viscous effect that could arise if one includes self-interaction among the dark-matter particles combines with the effective theory. It is shown that these two possible sources of dissipation can operate together in a cosmic fluid and the interplay between them can play an important role in determining dynamics of the cosmic fluid. In particular, we demonstrate that the viscosity coefficient due to self-interaction is added inversely with the viscosity calculated using effective theory of $\Lambda$CDM model. Thus the larger viscosity has less significant contribution in the effective viscosity. Using the known bounds on $\,\sigma/m$ for self-interacting dark-matter, where $\,\sigma\,$ and $m$ are the cross-section and mass of the dark-matter particles respectively, we discuss role of the effective viscosity in various cosmological scenarios.Comment: 7 pages, Updated to match with the published versio
