Expression for the relative change of height when the distance between the viewer and the body changes; and its cosmological applications

Imagine you are looking at a body, and then you keep moving behind from it. How does it appear? The body appears to be decreasing in height. So we normally use trigonometry to find the height, but it is always the third person and if we want to calculate the height of the body in the frame of reference of the viewer, hence we cannot use trigonometric ratios. So we need to derive a new expression; the relative height is dependent on; the distance between the bodies, the angle of sight and the original height. Also, we can apply this on heavenly bodies like any star that looks small from earth but is very large. So we can use the derived expression to find the radius of the star and the distance.

QoS optimization in wireless sensor networks using multi-hop multi clustering algorithm in a heterogeneous network

The method provided did improve the energy consumed for each simulation round is reduced and also the energy left is increased. The major breakthrough is that by implementing the proposed program the delay for each simulation round is not only greatly reduced but also uniformed, It is also clearly visible that the throughput in (bit per second) is drastically increased. When compared with traditional methods. The existing paper provides an interesting method using Lagrangian Relaxation(LR) to control the adaptive switching of hop-by-hop QoS routing. The method utilized timely information collection to validate and respect the QoS requirements of all the nodes making the whole network obeying the QoS parameter. This is done by utilizing the modified Markov Chain model for prediction. Multi-hop multi-cluster QoS algorithm using Matlab proposed and implemented a new optimized method our QoS based multi-path routing using ‘k’ neighbors based node switching in corresponding hops. The node will be switched if and only if the QoS threshold and distance threshold value is satisfied. The switching of nodes improved drastically on Throughput. The proposed algorithm has a little high drop ratio as compared to the existing algorithm which is partially due to the multi-path approach in packet splitting. If all the portions of the split packet are not received, the overall packet is dropped. This introduced a marginally higher packet drop ratio which can be managed later on and provides the scope for further improvement.

Fat Embolic Syndrome – Case Report

Fat Embolic Syndrome is a serious and life threatening condition. It occurs most frequently after fractures of long bones particularly the femur and tibia or intramedullary instrumentation for such bone fractures management. Some non-traumatic conditions such as diabetes mellitus, severe Burns, SLE and pancreatitis etc. can also result in Fat Embolic Syndrome. Young adults irrespective of sex are commonly affected. Its classical presentation consists of an asymptomatic interval following injury followed by pulmonary and neurological manifestations combined with petechial hemorrhages over the upper chest and axillae. The management of such cases needs to have high index of suspicions and aggressive approach to combat the condition with exclusion of other conditions. As this dreadful condition is a self-limiting one, the treatment of this condition remains mainly supervised supportive to the most affected organ system mainly pulmonary and cardiac. Mortality related to this condition is critical, starting from 10-20 %. Here is a description of such a fatal case managed well and the outcome was rewarding.

Review Paper

Review on Anthocyanins as herbal pH indicators

In the acid-base titrations, standard synthetic indicators are used to exhibit color change at different pH intervals. Anthocyanins (natural color pigments) in plants exhibit color changes with pH variations. The aim of this study is to investigate the activity of plant extracts, Rosa indica and Rubus occidentalis, to replace the synthetic indicators. Synthetic indicators cause chemical and environmental pollution, are toxic, expensive and rarely available. Methanolic extracts of Rosa indica and Rubus occidentalis exhibit sharp and intense color change in comparison to the standard synthetic indicators phenolphthalein and methyl orange. Herbal indicators are pollution-free, non-toxic, easily available and cost-effective.

Collusion in crowdsourced environments and factors that lead to it: A survey

Crowdsourcing is increasingly becoming a means by which individuals and organizations seek to solve problems. This is due to the advantages of crowdsourcing such as greater access to experts, lower costs of access to such experts and ubiquitous opportunities. Platforms are, however, plagued with the challenge of collusion between workers. This intern implies that crowdsourcing service providers will be paying out money for no work done leading to losses. This paper presents a survey on crowdsourcing, types of malicious attacks, motivation for workers to collude, factors that lead to collusion and the way tasks are allocated on these platforms.

Assessment of anti-hepatotoxic potential and antioxidant defence status of aqueous extract of trachyspermumammi seeds to paracetamol hepatotoxicity in albino rats

Aqueous extract of Trachyspermum Ammi seeds (AETAS) was evaluated for its hepatoprotective activities in rats. The plant extract (200 and 400mg/kg, p.o.) showed a remarkable hepatoprotective and antioxidant activity against paracetamol-induced hepatotoxicity is judged from the serum marker enzymes and antioxidant level. Paracetamol - induced significant rise in AST, ALT, ALP, Total bilirubin with a reduction of total protein, albumin, SOD, Catalase, GSH and marked rise in LPO level. Treatment of rats with different doses of plant extracts (200 and 400mg/kg) significantly altered serum marker enzymes, antioxidant levels to near normal against paracetamol treated rats. The activity of the extracts was comparable to the standard drug silymarin (100mg/kg, p.o). Results indicate the hepatoprotective properties of (AETAS) against paracetamol-induced hepatotoxicity in rats.
