Including the Fermion Vacuum Fluctuations in the (2+1)(2+1) flavor Polyakov Quark Meson Model

We consider the $(2+1)$ flavor Polyakov Quark Meson Model and study the effect of including fermion vacuum fluctuations on the thermodynamics and phase diagram. The resulting model predictions are compared to the recent QCD lattice simulations by the HotQCD and Wuppertal-Budapest collaborations. The variation of the thermodynamic quantities across the phase transition region becomes smoother. This results in better agreement with the lattice data. Depending on the value of the mass of the sigma meson, including the vacuum term results in either pushing the critical end point into higher values of the chemical potential or excluding the possibility of a critical end point altogether.Comment: 15 figures, some parts rewritten, new figures adde

Arthroscopic decompression and debridement for the treatment of anterior cruciate ligament ganglion cyst in a 45-year-old female

Anterior cruciate ligament (ACL) cysts are infrequently encountered in clinical practice, with limited reported cases. These cysts usually present with chronic knee pain and clinical examination is usually unremarkable except for knee tenderness. Due to the lack of characteristic symptoms and deficiency of precise clinical techniques to diagnose the condition, timely diagnosis requires a high index of suspicion, supported by magnetic resonance imaging (MRI). Hence management of ACL ganglion cysts poses unique challenges for healthcare providers. We present a case study of a 45-year-old female with an ACL ganglion cyst successfully treated with arthroscopic decompression and debridement. This article outlines the clinical presentation, diagnostic workup, surgical intervention, and post-operative outcomes of this case, providing insights into the effective management of this uncommon condition. Furthermore, we provide a comprehensive review of the existing literature on ACL ganglion cyst, emphasizing findings and treatment outcomes reported in previous studies. This case underscores the importance of considering ACL cysts in the differential diagnosis of knee pain and discomfort. Early identification and appropriate management, such as arthroscopic cyst excision, can lead to favorable outcomes and complete recovery

Fluctuations and Correlations of Conserved Charges in the (2+1)(2+1) Polyakov Quark Meson Model

We consider the $(2+1)$ flavor Polyakov Quark Meson Model and study the fluctuations (correlations) of conserved charges upto sixth (fourth) order. Comparison is made with lattice data wherever available and overall good qualitative agreement is found, more so for the case of the normalised susceptibilities. The model predictions for the ratio of susceptibilities go to that of an ideal gas of hadrons as in Hadron Resonance Gas Model at low temperatures while at high temperature the values are close to that of an ideal gas of massless quarks. Our study provides a strong basis for the use of PQM as an effective model to understand the topology of the QCD phase diagram.Comment: modified text, version accepted for publication in PR

Radiation and Magneticfield effects on Unsteady Natural Convection Flow of a Nanofluid Past an Infinite Vertical Plate with Heat Source

In this study, we analyze the effects of thermal radiation and magnetic field on unsteady natural convective flow of a nanofluid past an impulsively started infinite vertical plate in presence of heat source. The nanofluid contains Copper, Nikel, Zinc Oxide nanoparticles with water as base fluid. The partial differential equations governing the flow are solved numerically by Laplace Transform Technique. The effects of various parameters on velocity and temperature profiles examined and presented graphically .It is found that the increase in magnetic field causes the decrease in fluid velocity, fluid velocity and temperature profiles are more influenced by Radiation, Heat source and Volume fraction of the nanoparticles. Shape of nanoparticles does nots hows effect on the velocity of the fluid. Key Words: Heat transfer, Nanofluids, Thermal radiation, MHD, Heat source, Volume fraction

Natural Windbreaks Sustain Bird Diversity in a Tea- Dominated Landscape

Windbreaks often form networks of forest habitats that improve connectivity and thus conserve biodiversity, but little is known of such effects in the tropics. We determined bird species richness and community composition in windbreaks composed of remnant native vegetation amongst tea plantations (natural windbreaks), and compared it with the surrounding primary forests. Fifty-one, ten-minute point counts were conducted in each habitat type over three days. Despite the limited sampling period, our bird inventories in both natural windbreaks and primary forests were nearly complete, as indicated by bootstrap true richness estimator. Bird species richness and abundance between primary forests and windbreaks were similar, however a difference in bird community composition was observed. Abundances of important functional groups such as frugivores and insectivores did not vary between habitat types but nectarivores were more abundant in windbreaks, potentially as a result of the use of windbreaks as traveling routes, foraging and nesting sites. This preliminary study suggests that natural windbreaks may be important habitats for the persistence of bird species in a production landscape. However, a better understanding of the required physical and compositional characteristics for windbreaks to sustain bird communities is needed for effective conservation management

Epidemiology of type 2 diabetes: Indian scenario.

India leads the world with largest number of diabetic subjects earning the dubious distinction of being termed the "diabetes capital of the world". According to the Diabetes Atlas 2006 published by the International Diabetes Federation, the number of people with diabetes in India currently around 40.9 million is expected to rise to 69.9 million by 2025 unless urgent preventive steps are taken. The so called "Asian Indian Phenotype" refers to certain unique clinical and biochemical abnormalities in Indians which include increased insulin resistance, greater abdominal adiposity i.e., higher waist circumference despite lower body mass index, lower adiponectin and higher high sensitive C-reactive protein levels. This phenotype makes Asian Indians more prone to diabetes and premature coronary artery disease. At least a part of this is due to genetic factors. However, the primary driver of the epidemic of diabetes is the rapid epidemiological transition associated with changes in dietary patterns and decreased physical activity as evident from the higher prevalence of diabetes in the urban population. Even though the prevalence of microvascular complications of diabetes like retinopathy and nephropathy are comparatively lower in Indians, the prevalence of premature coronary artery disease is much higher in Indians compared to other ethnic groups. The most disturbing trend is the shift in age of onset of diabetes to a younger age in the recent years. This could have long lasting adverse effects on nation's health and economy. Early identification of at-risk individuals using simple screening tools like the Indian Diabetes Risk Score (IDRS) and appropriate lifestyle intervention would greatly help in preventing or postponing the onset of diabetes and thus reducing the burden on the community and the nation as a whole

Snakes of Telangana: An annotated checklist with new locality records and notes on natural history

With every growing human population and the resultant shrinkage of natural habitats, snakes are frequently encountered in and around human settlements, leading to widespread human-wildlife conflict. Conservation efforts involve rescue & relocation of 'stray' snakes, to mitigate snakebites, human deaths & snake mortality. We utilized snake rescue data of Friends of Snakes Society, Hyderabad, Telangana, recorded between the years 1995 and 2020, to present an annotated snake checklist for Telangana, along with their distribution. Further, opportunistic encounters and temporary captive care of the rescued species yielded significant insights into habitat preferences, dietary choices, aposematic responses, breeding cycles, etc., of various species of this region

Influence of posterior tibial slope on knee flexion in posterior stabilized fixed bearing primary total knee arthroplasty

Background: The goal of total knee arthroplasty (TKA) is to relieve pain and maintain stable range of motion (ROM) for day to day activities. Among the various factors, posterior tibial slope slope (PTS) may play an important role in achieving good postoperative knee flexion. Our study aims to know the effectiveness of PTS on the ROM of the knee in a posterior cruciate ligament (PCL)-substituting TKA.Methods: A total of 125 unilateral PCL-substituting TKA’s were included in the study. Based on postoperative PTA which was measured on lateral radiograph, patients were divided into 3 groups, Group A (PTS of ≤2) comprise of 24 patients. Group B consists of 91 patients (PTS of 3 to 7). Group C includes 10 patients (PTS of 8 or more). Functional outcome was measured by using knee society score (KSS) and Western Ontario and McMaster Universities osteoarthritis index (WOMAC) which were evaluated preoperatively and at 18months post operatively.Results: Mean postop ROM was 92.91 ± 10.632; 107.24±10.905; 107.49±13.944 in group A, B, C respectively which was significantly related to mean postop PTS (0.74; 5.62; 9.87 in group A, B, C respectively) (P<0.05). Functional outcome was measured by KSS and WOMAC which showed no significant difference pre and postoperatively.Conclusions: The results of our study validate the hypothesis that a positive correlation exists between the postoperative flexion and PTS in the PCL-substituting TKA, an increase in PTS can lead to a greater degree of the knee flexion for every extra degree of PTS.
