Simulation

In this paper, performance analysis of the Wireless and Wired computer networks through simulation has been attempted using OPNET as simulating tool. For wired networks, the performance parameters like delay and throughput have been investigated with varying transmission links and load balancers. The load-balancing has been analyzed through parameters like analysis of traffic sent and traffic received. While in wireless networks the metrics like delay, retransmission attempts and throughput have been estimated with varying physical characteristic and buffer size. From the obtained results, it is gathered that performance of the wired networks is good if high speed Ethernet links like 1000 Base X and server-load balancing policy are used whereas the performance of Wireless LAN can be improved by fine tuning and properly choosing the WLAN parameters. For the tested simulation scenarios the performance is observed to be better with wireless networks using infra-red type physical characteristics and higher buffer size (1024Kb

Laryngeal Neuroendocrine Tumor - An Atypical Presentation

Neuroendocrine tumors of the larynx are the most common non-epidermoid tumors of the larynx and comprise less than 1% of the laryngeal tumors. Most of the symptoms and presentation mimic any usual laryngeal malignancy making the diagnosis difficult. Here, we report a case of laryngeal neuroendocrine carcinoma that was managed with total laryngectomy

Methotrexate Induced Lung Injury in a Patient with Primary CNS Lymphoma: a Case Report

Methotrexate is an antimetabolite commonly used in clinical practice for a variety of indications ranging from rheumatoid arthritis and other connective tissue disorders to high dose regimens in many malignancies. This folate antagonist has got a spectrum of toxicities among which gastrointestinal effects predominate. Lung injury is a well described but rare event and has been reported most often in patients who have been on long term oral therapy for rheumatic disorders. Acute lung injury in a patient receiving a high dose regimen for haematological malignancies has not been reported previously. We present one such case of methotrexate related acute lung injury in a patient of primary CNS lymphoma receiving high dose methotrexate

A COST AND PIPELINE TRADE-OFF IN A TRANSPORTATION PROBLEM

Abstract: The present paper deals with a trade off between cost and pipeline at a given time in a transportation problem. The time lag between commissioning a project and the time when the last consignment of goods reaches the project site is an important factor. This motivates the study of a bi-criteria transportation problem at a pivotal time T . An exhaustive set E of all independent cost-pipeline pairs (called efficient pairs) at time T is constructed in such a way that each pair corresponds to a basic feasible solution and in turn, gives an optimal transportation schedule. A convergent algorithm has been proposed to determine non-dominated cost pipeline pairs in a criteria space instead of scanning the decision space, where the number of such pairs is large as compared to those found in the criteria space. 197 198 Vikas Sharma, Rita Malhotra, Vanita Verma / A Cost And Pipelin

Comparison of obstetric outcomes of pregnancies after donor oocyte IVF: Three-arm age-matched retrospective cohort study

Background: Oocyte donation has become widely used as a treatment option for infertile couples. The few available studies report conflicting evidence about the risk of hypertensive disorders in donor oocyte pregnancies after adjusting for maternal age and it is unclear whether pregnancy complications and obstetric risks are due to oocyte donation or to confounding factors such as maternal age. The aim of the present study was to evaluate and compare obstetric complications between women who conceived after oocyte donation and age-matched control women with spontaneous conception and self oocyte IVF conception.Methods : The present study comprised of women aged 20-45 years conceived from oocyte donation (n=104) between 1/12/2010 to 15/10/2017. Two age-matched control groups—Self oocyte IVF (n=150) and the other containing women who conceived spontaneously (n=312) were used for comparison of obstetric and perinatal outcomes.Results: Mean maternal age was statistically significantly higher in the Donor oocyte IVF group as compared to  self oocyte ivf and spontaneous conception group. Miscarriage, first trimester bleeding, pregnancy induced hypertension and gestational diabetes mellitus was significantly higher in Donor oocyte IVF group as compared to self-oocyte and spontaneous conception group (p=0.001). Using multiple logistic regression analysis age class adjusted PIH and GDM  incidence was significantly higher in donor oocyte group as compared to spontaneous conception (P=0.010).There was significant variation in perinatal outcomes between the three groups.Conclusion: Oocyte donation should be treated as an independent risk factor for miscarriage, first trimester bleeding, hypertensive disorder and gestational diabetes mellitus in pregnancy

A comprehensive review of new innovations in dental implant imaging techniques

Background: Over the past three decades, dentistry has undergone considerable development in all of its branches. The need for more accurate diagnostic methods have become inevitable with these progresses. Advanced imaging methods such as computed tomography, cone beam computed tomography, magnetic resonance imaging have also found space in modern dentistry from the traditional intra-oral periapical X-rays. Aim: This paper is intended to explore recent developments in imaging technology and its applications in various dental disciplines. Conclusion: The three - dimensional visualization has made the complex cranio-facial structures more available for analysis and early and precise diagnosis of deep rooted lesions. Clinical Significance: Moving from analog to digital radiography has not only made the process easier and quicker, but has also enabled image storage, manipulation (brightness/contrast, cropping of images, etc.) and recovery

Quantifying the Amount of Bleeding and Associated Changes in Intra-Abdominal Pressure and Mean Airway Pressure in Patients Undergoing Lumbar Fixation Surgeries: A Comparison of Three Positioning Systems

Study DesignProspective, randomised controlled, single centre study of 45 patients posted for two level lumbar fixation surgery in the prone position.PurposeTo compare intra-abdominal pressure (IAP), mean airway pressure mean airway pressure and blood loss during the spine surgery in prone position using three different positioning systems.Overview of LiteratureStudies have correlated IAP with the amount of perioperative bleeding. However, IAP and airway pressures while assessing the bleeding comparing two or more prone positioning systems are unclear.MethodsThis prospective study was conducted on a cohort of 45 patients scheduled for two-level lumbar fixation. Patients were randomly allocated to a spine table, Wilson's frame, and thermomodulated pads. Bladder pressure as an indicator of IAP, mean and peak airway pressures, and blood loss were monitored.ResultsIAP increased whenever patient position was changed to prone .The increase in pressure was more in the Wilson's frame group but was statistically significant only on prolonged positioning. Adopting the prone position always increased the mean airway pressure, but the increased was significant only in the Wilson's frame group. Mean airway pressure decreased in the spine table group and was statistically significant. The blood loss in the spine table group was significantly less as compared to the other groups.ConclusionsPositioning on a spine table results in less blood loss and low mean airway pressure. The Wilson's frame results in high IAP, increased mean airway pressure, and more blood loss. The thermomodulated frame increases mean airway pressure and produces a moderate increase in IAP and airway pressure

Myco-Biocontrol of Insect Pests: Factors Involved, Mechanism, and Regulation

The growing demand for reducing chemical inputs in agriculture and increased resistance to insecticides have provided great impetus to the development of alternative forms of insect-pest control. Myco-biocontrol offers an attractive alternative to the use of chemical pesticides. Myco-biocontrol agents are naturally occurring organisms which are perceived as less damaging to the environment. Their mode of action appears little complex which makes it highly unlikely that resistance could be developed to a biopesticide. Past research has shown some promise of the use of fungi as a selective pesticide. The current paper updates us about the recent progress in the field of myco-biocontrol of insect pests and their possible mechanism of action to further enhance our understanding about the biological control of insect pests
