Debt, Deficits and Inflation: An Application to the Public Finances of India

The paper studies the solvency of the Indian public sector and the eventual monetization and inflation implied by stabilization of the debt-GNP ratio without any changes in the primary deficit. The nonstationarity of the discounted public debt suggests that indefinite continuation of the pattern of behavior reflected in the historical discounted debt process is inconsistent with the maintenance of solvency. This message is reinforced by the recent behavior of the debt-GNP ratio and the ratio of primary surplus plus seigniorage to GNP. Our estimates of the base money demand function suggest that even maximal use of seigniorage will not be sufficient to restore solvency.

Trace gas transport in the subsurface of Mars

The ExoMars Trace Gas Orbiter (TGO) will have the capability of detecting and characterizing a broad suite of trace gases in the atmosphere of Mars. Interpreting the results of this mission will require an understanding of how these trace gases are transported from their sources, which may be deep underground, to the atmosphere. Here we present results of modeling designed to measure the timescales of release from putative subsurface methane sources. These transport timescales are far longer than mixing times in the atmosphere and could be up to 10 million years

Studies on Fruit and Yield Traits in Indigenous Coloured Varieties of Mango (Mangifera indica L.) in South Gujarat, India

An investigation on fruit descriptors and yield in twelve mango varieties was conducted under South Gujarat conditions. Maximum fruit length was recorded in cv. Totapuri (16.23cm). Vanraj showed the highest values for fruit width (11.67cm), fruit circumference (37.37cm), fruit weight (729g), fruit volume (575.59cm3) and fruit pulp (78.93%). Maximum TSS (21.20%), acidity (0.42%) and fruit firmness (7.00 rating) was observed in cvs. Deshi-1, Deshi-3 and Makaram, respectively. 'Totapuri' had maximum total shelf-life (21.33 days), number of fruits per tree (383.00) and fruit yield (236.80kg/tree). The varieties had green to yellow ground-colour of peel. All the varieties had red-blush peel colour, excepting cvs. Dadamio, Makaram and Swarnarekha which were purplish-red. Similarly, pulp colour ranged from light yellow to light orange. Based on overall performance, cvs. Alphonso, Deshi-1, Deshi-2, Kesar, Khandesi Borasio, Totapuri and Vanraj proved to be superior to the other varieties

Reduction of cogging torque of radial flux permanent magnet brushless DC motor by magnet shifting technique

  Introduction. In spite of many advantages of radial flux permanent magnet brushless DC motors it suffers from the distinct disadvantage of high cogging torque. The designer must emphasize to reduce the cogging torque during the design stage. This paper introduces magnet shifting technique to mitigate cogging torque of surface mounted radial flux brushless DC motor. Methodology. Initially 200 W, 1000 rpm surface mounted radial flux permanent magnet brushless DC motor is designed with symmetrical placement of permanent magnets with respect to each other on rotor core. Cogging torque profile of this initial motor is obtained by performing finite element modelling and analysis. Originality. This design has been improved by shifting the position of permanent magnets with respect to adjacent permanent magnets. The effect of magnet shifting on cogging torque has been analyzed by performing finite element analysis. Results. It has been examined that the peak to peak cogging torque is decreased from 1.1 N×m to 0.6 N×m with shifting of permanent magnets respectively.Вступ. Незважаючи на багато переваг безщіткових двигунів постійного струму з радіальним магнітним потоком, вони мають явний недолік, що полягає у високому крутному моменті зубчатої передачі. Проектувальник повинен зосередитись на зниженні крутного моменту зубчатої передачі на етапі проектування. У цій статті представлена методика зсуву магніту для зменшення крутного моменту зубчатої передачі безщіткового двигуна постійного струму з радіальним потоком, встановленого на поверхні. Методологія. Спочатку безщітковий двигун постійного струму з радіальним магнітним потоком потужністю 200 Вт, 1000 об/хв спроектований із симетричним розміщенням постійних магнітів відносно один одного на сердечнику ротора. Розподіл крутного моменту зубчатої передачі цього початкового двигуна отриманий шляхом аналізу методом скінчених елементів (МСЕ). Оригінальність. Ця конструкція була вдосконалена за рахунок зсуву положення постійних магнітів по відношенню до сусідніх постійних магнітів. Вплив зсуву магніту на крутний момент зубчатої передачі було проаналізовано за допомогою аналізу МСЕ. Результати. Досліджено, що піковий крутний  момент зубчатої передачі зменшився з 1,1 Н×м до 0,6 Н×м, відповідно, при зсуві постійних магнітів

Study of outcomes of suprapatellar approach for tibia intramedullary nailing in patients coming to rural medical college, Loni

Background: Tibia shaft fractures are most common lower limb long bone fractures. In approximately 80% of patients, tibia fracture occurs in diaphysis region. The procedure of intramedullary interlocking nailing is done by positioning the injured extremity at minimum of 90 degree of flexion in the knee joint to achieve optimal exposure of correct entry point. The tension of quadriceps tendon causes a typical apex anterior angulation of proximal fragment. Supra patellar nailing is done with knee in semi extended position, reducing the anterior angulation. The aim of this study is to study outcomes of supra patellar access of intramedullary nailing for tibia fractures.Methods: It is a descriptive longitudinal study which was carried out from October 2019 to September 2021 in Dr. Balasaheb Vikhe Patil rural medical college, Loni, Ahmednagar. In this study 60 case of closed shaft tibia fractures were treated by supra-patellar nailing technique.Results: In our study we selected, 60 patients with tibia fracture admitting in our institute. All patients underwent operative procedure in the form of intramedullary interlocking tibia nail which was done with suprapatellar approach. Out of all the 60 patients treated with suprapatellar approach, excellent results with good range of movements with excellent lower extremity functional scale score.Conclusions: Supra-patellar approach was found to provide excellent outcome for proximal 1/3rd of tibia fracture

VITAMIN D RECEPTOR (VDR) GENE POLYMORPHISM AND MATERNAL VITAMIN D DEFICIENCY IN INDIAN WOMEN WITH PRETERM BIRTH (PTB)

  Objective: Preterm birth (PTB) is the leading cause of high infant mortality and long-term disability in young children worldwide. Array of adverse maternal and fetal outcomes linked with vitamin D level and its associated vitamin D receptor (VDR) gene. We undertook this study to investigate the association between VDR gene polymorphism with vitamin D deficiency and PTB in West Indian pregnant women.Methods: A total of 72 women with PTB and 138 healthy mothers with uncomplicated normal delivery were selected from different regions of Gujarat, India. FokI and TaqI single nucleotide polymorphism (SNP) of VDR gene determined by polymerase chain reaction and restriction fragment length polymorphism. Vitamin D level was determined using enzyme-linked immunosorbent assay.Result: ff genotype (29.17% vs. 10.87%, p=0.002) and f allele (49.31% vs. 35.51%, p=0.006) frequency distributions of VDR FokI showed significantly (odds ratio=0.566, 95% confidence interval=0.368-0.870, p=0.006) higher in women with preterm delivery than in control full term group. Genotype frequency of VDR TaqI showed no significant difference between preterm group and control.Conclusion: These results confirmed that women carrying ff genotype of FokI gene had significantly higher risk for vitamin D deficiency which enhances the risk of prematurity than women carrying FF genotype in West Indian women

Elevated interferon-stimulated gene transcription in peripheral blood mononuclear cells occurs in patients infected with genotype 1 but not genotype 3 hepatitis C virus

Hepatitis C virus (HCV) can be classified into seven distinct genotypes that are associated with differing pathologies and respond differently to antiviral therapy. In the UK, genotype 1 and 3 are present in approximately equal proportions. Chronic infection with HCV genotype 3 is associated with increased liver steatosis and reduced peripheral total cholesterol levels, which potentially influences peripheral immune responses. To understand these differences, we investigated host gene transcription in peripheral blood mononuclear cells by microarray and quantitative PCR in patients with genotype 1 (n = 22) or genotype 3 infection (n = 22) and matched healthy controls (n = 15). Enrichment of genes involved in immune response and inflammatory pathways were present in patients infected with HCV genotype 1; however, no differences in genes involved in lipid or cholesterol metabolism were detected. This genotype-specific induction of genes is unrelated to IL28B genotype or previous treatment failure. Our data support the hypothesis that genotype 1 infection drives a skewed Type I interferon response and provides a foundation for future investigations into the host–pathogen interactions that underlie the genotype-specific clinical outcomes of chronic HCV infection

Submillimeter-wave emission of three Galactic red novae: cool molecular outflows produced by stellar mergers

Red novae are optical transients erupting at luminosities typically higher than those of classical novae. Their outbursts are believed to be caused by stellar mergers. We present millimeter/submillimeter-wave observations with ALMA and SMA of the three best known Galactic red novae, V4332 Sgr, V1309 Sco, and V838 Mon. The observations were taken 22, 8, and 14 yr after their respective eruptions and reveal the presence of molecular gas at excitation temperatures of 35-200 K. The gas displays molecular emission in rotational transitions with very broad lines (full width $\sim$400 km\s). We found emission of CO, SiO, SO, SO$_2$ (in all three red novae), H$_2$S (covered only in V838 Mon) and AlO (present in V4332 Sgr and V1309 Sco). No anomalies were found in the isotopic composition of the molecular material and the chemical (molecular) compositions of the three red novae appear similar to those of oxygen-rich envelopes of classical evolved stars (RSGs, AGBs, post-AGBs). The minimum masses of the molecular material that most likely was dispersed in the red-nova eruptions are 0.1, 0.01, and 10$^{-4}$ M$_{\odot}$ for V838 Mon, V4332 Sgr, and V1309 Sco, respectively. The molecular outflows in V4332 Sgr and V1309 Sco are spatially resolved and appear bipolar. The kinematic distances to V1309 Sco and V4332 Sgr are 2.1 and 4.2 kpc, respectively. The kinetic energy stored in the ejecta of the two older red-nova remnants of V838 Mon and V4332 Sgr is of order $10^{46}$ erg, similar to values found for some post-AGB (pre-PN) objects whose bipolar ejecta were also formed in a short-duration eruption. Our observations strengthen the link between these post-AGB objects and red novae and support the hypothesis that some of the post-AGB objects were formed in a common-envelope ejection event or its most catastrophic outcome, a merger.Comment: 19 pages, 13 figures, accepted to A&
