USB to USB Data Transfer using Raspberry Pi and ARM

Abstract: An importance of portability is well known to us so to achieve this, we are going to design a system which we can carry anywhere. Using this system we can not only transfer data but also we are able to see the transfer of the particular file which we are going to transfer by using graphical display .Hence the system to be designed will be more compact .In our project we are going transfer data between different USB devices using Raspberry pi and ARM7 without using any computer or laptop .As shown in block diagram four USB devices can be connected to Raspberry pi while one USB device can be connected to ARM 7.Out of these various devices one device can act as a master while others will act as slaves. After sending particular command to processor ,the processor will start fetching data from master USB device and ARM processor will wait from the signal from destination or slave USB.As soon as processor gets the signal from destination device data transfer operation get started

Proposed Method for Sewage Treatment

The aim of the study was to invent the new system for treating the waste water to minimize the problems occurs due to the sewage water. And as the existing system faces so many problems; few of them eventually not in working position. So the money requires to operate and maintain the existing plant is more over than expecting so the newly proposed system is beneficial in this case.  The newly invented system consist of the weight unit in which the sewage is probably separate out. In weight unit we use the rod and plate and it operate automatically when the waste water is passed through it and then the sewage is separated. While designing the newly invented sewage system the discharge of the sewage taken in account and the sewage characteristics decide what type of filter should use to filter the water

Heart failure and kidney dysfunction: epidemiology, mechanisms and management.

Heart failure (HF) is a major health-care problem and the prognosis of affected patients is poor. HF often coexists with a number of comorbidities of which declining renal function is of particular importance. A loss of glomerular filtration rate, as in acute kidney injury (AKI) or chronic kidney disease (CKD), independently predicts mortality and accelerates the overall progression of cardiovascular disease and HF. Importantly, cardiac and renal diseases interact in a complex bidirectional and interdependent manner in both acute and chronic settings. From a pathophysiological perspective, cardiac and renal diseases share a number of common pathways, including inflammatory and direct, cellular immune-mediated mechanisms; stress-mediated and (neuro)hormonal responses; metabolic and nutritional changes including bone and mineral disorder, altered haemodynamic and acid-base or fluid status; and the development of anaemia. In an effort to better understand the important crosstalk between the two organs, classifications such as the cardio-renal syndromes were developed. This classification might lead to a more precise understanding of the complex interdependent pathophysiology of cardiac and renal diseases. In light of exceptionally high mortality associated with coexisting HF and kidney disease, this Review describes important crosstalk between the heart and kidney, with a focus on HF and kidney disease in the acute and chronic settings. Underlying molecular and cellular pathomechanisms in HF, AKI and CKD are discussed in addition to current and future therapeutic approaches
