Experimental Investigation on Churning Power Loss of Splash Lubricated Worm Gear

Churning power losses are a complex phenomenon that produces critical power losses when considering the splash lubrication of gear units. This article describes the method to investigate the churning power loss in a worm gearbox. A particular test rig was designed and fabricated to experiment on single start worm gear incompletely submerged in an oil bath. The direct torque measurement technique was used to determine the churning power losses. Experiments have been conducted to determine the impact of a variety of operating conditions on churning power losses, including worm speeds, gear immersion depth, lubricant temperatures, and lubricant type (mineral and synthetic). It was found that the churning losses were significantly affected by the worm shaft orientation, speed of gear, and the depth of immersion (static head). The lubricant's temperature is more essential than the type of lubricant in terms of churning power loss

INCIDENCES OF-AND RISK FACTOR FOR NEW ONSET DIABETES AFTER TRANSPLANTATION IN LIVE DONOR KIDNEY TRANSPLANTATION: A PROSPECTIVE SINGLE CENTRE STUDY

Objective: The objective of present study was to evaluate incidence and risk factors for the development of new-onset diabetes after transplantation (NODAT) after kidney transplantation at our center.Methods: A total 79 nondiabetic patients who underwent living donor kidney transplantation from January 2014 to August 2014 were prospectively enrolled. All the patients were followed for one year. All the patients received the same protocol of immunosuppressive therapy. NODAT was defined as if a patient had HbA1c ≥ 6.5%, fasting venous plasma glucose ≥126 mg/dl, or was receiving diet or medical therapy for diabetes.Results: The incidence of NODAT was 29.9% after one year. Risk factors associated with the development of NODAT included older age (OR: 1.07; p<0.05), family history (OR: 3.58; P<0.05), hepatitis C virus (HCV) positivity (OR: 11.15; p<0.05), obesity (OR: 4.28; p<0.05), pre-transplant triglycerides (OR: 1.01; p<0.005) and cholesterol level (OR: 1.01; p<0.005).Conclusion: The prevalence of potentially modifiable risk factors in our study cohort was overweight recipients and pretransplant HCV infection, serum triglycerides, and cholesterol levels.Keywords: New-onset Diabetes after transplantation, Kidney transplantation, Tacrolimus, Hepatitis C virus

Money for Nothing and Privacy for Free?

Privacy in the context of ubiquitous social computing systems has become a major concern for the society at large. As the number of online social computing systems that collect user data grows, this privacy threat is further exacerbated. There has been some work (both, recent and older) on addressing these privacy concerns. These approaches typically require extra computational resources, which might be beneficial where privacy is concerned, but when dealing with Green Computing and sustainability, this is not a great option. Spending more computation time results in spending more energy and more resources that make the software system less sustainable. Ideally, what we would like are techniques for designing software systems that address these privacy concerns but which are also sustainable - systems where privacy could be achieved "for free," i.e., without having to spend extra computational effort. In this paper, we describe how privacy can be achieved for free - an accidental and beneficial side effect of doing some existing computation - and what types of privacy threats it can mitigate. More precisely, we describe a "Privacy for Free" design pattern and show its feasibility, sustainability, and utility in building complex social computing systems

Ovarian hyper stimulation syndrome in a spontaneous singleton pregnancy: a case report

Ovarian hyper stimulation syndrome (OHSS) is extremely rare in spontaneous pregnancies. Spontaneous OHSS can result from glycoprotein hormones stimulating follicle-stimulating hormone receptors (FSHR). Our case reinforces the importance of a prompt diagnosis and management in all pregnant patients presenting with acute abdomen and ovarian masses. We report a case of spontaneous singleton pregnancy at 12-week POG presented with abdominal distension and enlarged ovaries. Patient was successfully managed with supportive treatment comprise of intravenous (IV) Albumin, thromboprophylaxis, dopamine agonist and insulin sensitizer. Spontaneous OHSS should be included in the differential diagnosis of acute abdomen in pregnant women. Since spontaneous OHSS can be associated with life-threatening complications, it requires early diagnosis for successful management. The etiology should be determined in order to focus the treatment and avoid future complications.

Facial Emotion Recognition usign CNN

Nowadays where most of the works are being carried online the demand for face recognition technique is elevated. Computerized software is assisting in identifying human feelings such as happiness, sadness, anger, fear, disgust, etc. Over the decades, various research has been carried on the facial expression and emotion recognition. Emotion detection has extended applications. It is not merely related to any specific field nut instead the approach ranges from communication, advertising to hospital requisition and many more. To exist collective mechanisms through which we can accomplish the process of facial emotion recognition. In this paper we are using Convolutional Neural Network for the implementation. Upon exploring numerous datasets for the procedure of experiment we have chosen to go with Kaggle dataset

Formulation Development Of Nanoparticulate Formulation In Ophthalmic Drug Delivery System

The major challenge faced by today’s pharmacologist and formulation scientist is ocular drug delivery. Topical eye drop is the most convenient and patient compliant route of drug administration, especially for the treatment of anterior segment diseases. Delivery of drugs to the targeted ocular tissues is restricted by various precorneal, dynamic and static ocular barriers. Also, therapeutic drug levels are not maintained for longer duration in target tissues. So, the present work on ocular drug delivery research make advanced towards developing a novel, safe and patient compliant formulation and drug delivery devices/techniques, which may surpass these barriers and maintain drug levels in tissues. Anterior segment drug delivery advances are witnessed by modulation of conventional topical solutions with permeation and viscosity enhancers. Also, it includes development of nano formulations have also been introduced for anterior segment ocular drug delivery. these novel devices and/or formulations are easy to formulate, no/negligibly irritating, possess high precorneal residence time, sustain the drug release, and enhance ocular bioavailability of therapeutics. An update of current research advancement in ocular drug delivery necessitates and helps drug delivery scientists to modulate their process and develop novel and safe drug delivery strategies followed by current nanotechnology-based formulation developments and also, recent developments with other ocular drug delivery strategies employing in situ formulation. &nbsp
