Van der Waals black hole

In the context of extended phase space, where the negative cosmological constant is treated as a thermodynamic pressure in the first law of black hole thermodynamics, we find an asymptotically AdS metric whose thermodynamics matches exactly that of the Van der Waals fluid. However, we show that as a solution of Einstein's equations, the corresponding stress energy tensor does not obey any of the energy conditions everywhere outside of the horizon.Comment: 4 pages, 1 figure v3: corrected statements about energy condition

Householder Savings & Investment Behavior in Theni District

Investment of hard earned money is a crucial activity of every human being. Investment is one of the foremost concerns of every individual investor as their small savings of today is to meet the expenses of tomorrow. This study deals with investors\u27 preference of Shares, Debentures, Mutual fund, Bank deposits, and Life insurance, etc. Savings of the people are invested in assets depending on their risk and return demands, the safety of money, liquidity, the available avenues for investment, various financial institutions, etc. In a developing country like India, householder savings and investment is the major source of capital for economic activities. Hence, a study of investment behavior of households has to understand the level of knowledge of householders about investment. If the saving is low, then the investment will also be low leading to low capital formation. The present paper explains different reasons for savings, awareness level and the association between demographic factors and awareness level among householders of Theni district

ABHRAK BHASMA AND SiO2 INFLUENCED FREE RADICAL STATUS IN LIVER AND KIDNEY OF CCl4-INDUCED ACUTELY INTOXICATED MALE ALBINO RAT

Objective: The objective of the study was to study the mechanism of action of abhrak bhasma-mediated liver and kidney protection in CCl4-induced acute hepatotoxicity-induced male albino rats. Action of abhrak bhasma is compared with the action of SiO2 in similar experimental conditions to differentiate the role of silicon. Methods: Male albino rats (Rattus norvegicus) were used for experiments. The acute hepatotoxicity was induced by daily dose of CCl4 (3.0 ml/kg body wt for 7 days consecutive). Concurrent treatment of abhrak bhasma in graded doses (10, 20, 30, and 40 mg) was given for 7 days (PO). SiO2 (10, 20, 30, and 40 mg) in graded doses was also given in independent groups of rats as silica control. Lipid peroxidation (LPO) in liver and kidney was studied by malondialdehyde (MDA) estimations as parameter of toxicity and also to study protection. Results: CCl4-induced hepatotoxicity (MDA levels) is partially managed by low doses of SiO2 but not by high doses. Abhrak bhasma hepatoprotective activities were dose dependent. A 40 mg dose maintained normal levels of LPO. Abhrak bhasma also protected associated renal toxicity. Conclusion: Abhrak bhasma protected CCl4-induced hepatotoxicity and also associated renal toxicity. Silicon from both SiO2 and abhrak bhasma is hepatoprotective in 10 ml doses (10 and 20 mg) but silicon processed in abhrak bhasma by traditional Ayurvedic processes increased its potency and hepatoprotection and added the potency of renal protection

An audit of hysterectomies: indications, complications and clinico pathological analysis of hysterectomy specimens in a tertiary care center

Background: Hysterectomy is the commonest major surgical procedure performed in gynecology. It is an effective treatment option for many gynecological conditions. Aim and objective of the study was to analyse the indications, complications of hysterectomies and to see whether preoperative clinical diagnosis was confirmed by histopathology.Methods: Authors present a retrospective study of 198 hysterectomised cases over a period of one year from January 2016 to December 2016. The data regarding patients age, parity, indication for hysterectomy, type of hysterectomy, complications during and after surgery and final histopathological diagnosis were collected from the records and analysed.Results: A total of 198 cases of hysterectomies were studied. Hysterectomies were distributed over a wide age ranging from 32 years to 75 years. Most common age group was 41-50 years. Majority were done through abdominal route 162 cases (81%). Most common indication was abnormal uterine bleeding 56 (28%) and fibroid 41 (21%). One case of accidental bladder injury was noted. Most common postoperative complication was fever (23%). Most common histopathological lesion was fibroid 101 (51%). In three cases preoperative clinical diagnosis did not correlate with final histopathological diagnosis.Conclusions: As any surgical procedure, hysterectomy is also associated with risk of complications. Hence the indication should be carefully evaluated. Reporting of all hysterectomies should be made mandatory and audit results should be used for improvement of quality of health service. Newer and less invasive treatment options should be offered to women with benign pathologies. This will further reduce the incidence of hysterectomy

Two-dimensional surface properties of 2-methoxy ethyl oleate at the air/water interface

Methoxy ethyl oleate, a nonionic surfactant, has been investigated at the air/water interface for various surface properties by employing the Langmuir film balance technique. The ester forms an expanded isotherm at the air/water interface. The minimum area of packing (A0), initial area of increase of surface pressure (Ai), collapse pressure (πc), and area/molecule at collapse pressure (Ac) have been estimated from the isotherm curve. The higher compressibility coefficient (K) suggests that the ester forms a more expanded liquid film than the parent oleic acid. Besides, the ester film is fairly stable as suggested by only about 30% loss in area over a period of 20 min. The relaxation rates of the ester film at different surface pressures of 10, 15, and 20 mN.m-1 have been estimated from changes in the surface area/molecule with time. Interestingly, the surface area (54.2 Å2/molecule) that corresponds to a minimized structure projected for the ester, calculated theoretically, agrees reasonably well with the experimental value (57.2 Å2/molecule)

Evaluation of outcome of pregnancy in placenta accreta spectrum

Background: Aim of the study was to evaluate the outcome of pregnancy in placenta accrete spectrum in third trimester pregnancy at tertiary care centreMethods: This hospital based retrospective study was carried out from 2017 to 2019.  The case records of all women identified as placenta accrete spectrum from the hospital registers were retrieved. A total of 166 patients with the diagnosis of placenta accrete spectrum were included in the study.Results: The incidence of morbidly adherent placenta is 5 per 10,000 deliveries with mean age being 32.4±4.2 (23-39) years. and showed its relation with risk factors such as previous caesarean section (CS), placenta praevia and multiparity. The mean duration of MICU stay in placenta previa was 6.7±1.9 days (range 2-12 days). With complications in 18 cases of which urinary bladder injury (3%), infection (9%), PPH and coagulopathy (4.2%). The placenta was removed successfully in 141 while 25 cases had caesarean hysterectomy (2.4%). In total 166 cases 26 (16.8%) cases are intrauterine device (IUD) and still births. 5 (3%) cases are very low birth weight, 24 cases (14.5%) are low birth weight babies, 76 (45.8%) cases had neonatal intensive care unit (NICU) admissions followed by 10 (6%) cases with <5 APGAR score.Conclusions: Placenta accreta spectrum can be identified antenatally with a high index of suspicion in the presence of known risk factors and proper radiological studies, allowing for planned attempts to avoid life-threatening haemorrhage and caesarean hysterectomy
