Bank Deposits in India – Econometric Analysis of Macroeconomic Determinants

In this paper, we examined various macroeconomic determinants of bank deposits in India using monthly data for period January 2011 to December 2015. The determinants are money supply, inflation, index of industrial production, Treasury bill rate, repo rate and stock market index measured by sensex, an index of shares of thirty companies listed in Bombay Stock Exchange. ADF and Phillips-Peron tests show that all variables are first difference stationary while Trace Test find 4 co-integrating vector at 4 lags. Hence Johansen Cointegration methods indicate that there is long run relationship among the variables and the Vector Error Correction model shows a satisfactory speed of adjustment. VECM estimates showed that money supply, index of industrial production and Treasury bill rates are statistically significant at various lags with the money supply having positive impact on the amount of deposits whereas IIP and Treasury bill rate have negative impact on deposits. Granger Causality test find that only index of industrial production granger cause deposits whereas deposits granger cause both money supply and Treasury bill rates. Impulse Response Function also shows similar results. Keywords: Bank Deposits, macroeconomic determinants, Treasury bills rates, inflation, Money supply, Repo rate, Vector Error Correction Model, Granger Causality, and Impulse Response Function.

Patellar Tendinopathy: “Jumper’s Knee”

“Patellar tendinopathy” is also known as “Jumper’s knee” and is a common cause of impaired function in athletes who participate in sports that require jumping and running activities. The exact etiology of disease is still unknown and several theories have been postulated for its pathogenesis. It usually presents as anterior knee pain that is related to the sports activity and might lead to decreased sports participation. USG and MRI are the main modality of investigation that aids in the diagnosis. Non-operative therapy forms the main stay of treatment in form of rest, brace, physical therapy and anti-inflammatory medications. Other adjuncts such as cryotherapy, corticosteroids injection, platelet -rich plasma injections and electrical therapy like TENS or ESWT have been used with some success. Operative intervention in form of open or arthroscopic procedures are reserved for chronic and refractory cases

A systematic review of reactivation of tuberculosis due to use of corticosteroids for COVID-19 treatment between January 2020 to January 2022

Coronavirus-19 disease became a matter of concern for the whole world and WHO declared it as pandemic on 11 March 2020. Soon a number of clinical trials started to check for the treatment modalities, to compare their efficacy and safety. Out of which corticosteroids in trials showed decrease in mortality in severe COVID-19 patients. However existing diseases such as tuberculosis still remains a leading killer and matter of concern. One out of four individuals are said to be having tuberculosis (mostly in inactive form or latent form) but there remains a threat of reactivation of tuberculosis in presence of risk factors such as corticosteroid administration as it causes immunosuppression. This is a retrospective observational study on reactivation of tuberculosis due to corticosteroids used in COVID-19 treatment. Most commonly given corticosteroid was found to be dexamethasone and the duration of corticosteroid therapy ranged between 5 to 12 days. Majority of patients (5 out of 6) showed reactivation of tuberculosis within 30 days of starting of corticosteroid therapy and most common co-morbidity associated was found to be diabetes mellitus followed by hypertension in such patients. Symptoms of 4 out of 6 patients resolved after starting of anti-tubercular therapy

COVID-19 and tuberculosis reactivation: a systematic review assessing most common risk factors

COVID-19 as a pandemic not only shifted the focus of the healthcare system from other diseases but also affected the disease progression of infections like tuberculosis which remained a leading killer in the past worldwide. COVID-19 itself is said to reactivate latent tuberculosis as shown in animal experiments. Immunomodulators such as corticosteroids and tocilizumab which are being used for covid treatment even further predisposes patients to tuberculosis reactivation and increased progression of the disease. Diabetes is already known to be a risk factor for tuberculosis reactivation and impact tuberculosis progression and worsen the situation. The exact mechanism of interaction of covid-19 and tuberculosis and their effect on each other remains unknown. Considering high prevalence of tuberculosis and the current scenario of covid-19 in world, there is need to study the impact of covid-19 infection on tuberculosis progression or reactivation and commonly associated risk factors. We conducted a systematic search of the online databases to collect data of patients who had tuberculosis reactivation or increased progression of disease after covid-19 infection. Data of a total of 18 patients was retrieved and used for the syntheses of the study. Diabetes was present in 50% of the patients. 55.5% patients were administered corticosteroids for covid-19 treatment later presenting with tuberculosis. Tocilizumab however was administered to 22.2% patients who also received corticosteroids. 27.7% patients suffered tuberculosis reactivation after covid-19 infection without history of diabetes and corticosteroid or tocilizumab administration. None of the patients were reported to have HIV infection. Major risk factors present in patients included corticosteroid administration and diabetes. However, tuberculosis reactivation was seen even in absence of these factors indicating that covid-19 infection may itself be responsible for tuberculosis reactivation. The exact mechanism however remains unknown and further clinical studies are needed to know the same

Constraining a spatially dependent rotation of the Cosmic Microwave Background Polarization

Following Kamionkowski (2008), a quadratic estimator of the rotation of the plane of polarization of the CMB is constructed. This statistic can estimate a spatially varying rotation angle. We use this estimator to quantify the prospects of detecting such a rotation field with forthcoming experiments. For PLANCK and CMBPol we find that the estimator containing the product of the E and B components of the polarization field is the most sensitive. The variance of this EB estimator, N(L) is roughly independent of the multipole L, and is only weakly dependent on the instrumental beam. For FWHM of the beam size ~ 5'-50', and instrument noise $\Delta_p ~ 5-50 uK-arcmin, the scaling of variance N(L) can be fitted by a power law N(L)=3.3 x 10^{-7} \Delta^2_p (FWHM)^{1.3} sq-deg. For small instrumental noise \Delta_p \leq 5 uK-arcmin, the lensing B-modes become important, saturating the variance to ~10^{-6} sq-deg even for an ideal experiment. Upcoming experiments like PLANCK will be able to detect a power spectrum of the rotation angle, C^{\alpha \alpha}(L), as small as 0.01 sq-deg, while futuristic experiment like CMBPol will be able to detect rotation angle power spectrum as small as 2.5 x 10^{-5} sq-deg. We discuss the implications of such constraints, both for the various physical effects that can rotate the polarization as photons travel from the last scattering surface as well as for constraints on instrumental systematics that can also lead to a spurious rotation signal. Rotation of the CMB polarization generates B-modes which will act as contamination for the primordial B-modes detection. We discuss an application of our estimator to de-rotate the CMB to increase the sensitivity for the primordial B-modes.Comment: 11 pages, 5 figure

Study on Design and Simulation of Temperature Control System

Temperature control system is a complicated process which maintains the temperature in a particular defined area to a certain maxima or minima level. In recent times, we are witnessing a rapid growth in industries at global level which has led to globalization and industrialization which further has led the necessary use of the temperature control system and its application in these industries at day-to-day level in manufacturing and maintenance with the increase in the greenhouse effect and depletion of ozone layer. Many factories always maintain a certain area or say a section of operation in their infrastructure that must maintain a range of temperature for process to work successfully. The laboratories of research uncertainly sometimes lack in the use of temperature control system which has further necessitated the use of large chambers of different sizes to perform specific temperature related re-search work which further led to the increase in the cost of re-search work. In certain spe-cific areas there are lot of electronic activities happening or some machinery function like in the server rooms or the area where production plant is, so basically these places work constantly for 24hrs and during the whole day the temperature has to be monitored precisely and frequently so that it can be ensured that the temperature do not instantly rise or fall below the marked temperature which may lead to the acceleration of wearing and tearing of whole system. Living rooms, hospitals, malls, aircrafts etc., are also one of the most important places where monitoring of temperature is required so as to ensure that the thermal comfort is ensured, and thermal comfort here means that the state of mind which feels satisfied with the temperature in the present environment. This is im-portant because if there will be any dissatisfaction with the thermal environment then it can cause the body to be too warm or too by unwanted heating and unwanted cooling of the equipment may further lead to the functional disbalance
