This document discusses location verification in wireless sensor networks. It describes two categories of location verification: on-spot verification and in-region verification. On-spot verification checks if a sensor's estimated location matches its true location, while in-region verification checks if a sensor is located within an application-specific region. The document proposes two lightweight algorithms, GFM and GFT, for on-spot verification using neighborhood observations. It also describes a probabilistic algorithm to compute the confidence that a sensor is inside the verification region for in-region verification. The proposed verification system can effectively verify sensor locations without relying on specialized hardware or deployment knowledge, making it suitable for low-cost wireless sensor networks.
Wireless sensor networks localization algorithms a comprehensive surveyIJCNCJournal
Wireless sensor networks (WSNs) have recently gained a lot of attention by scientific community. Small
and inexpensive devices with low energy consumption and limited computing resources are increasingly
being adopted in different application scenarios including environmental monitoring, target tracking and
biomedical health monitoring. In many such applications, node localization is inherently one of the system
parameters. Localization process is necessary to report the origin of events, routing and to answer
questions on the network coverage ,assist group querying of sensors. In general, localization schemes are
classified into two broad categories: range-based and range-free. However, it is difficult to classify hybrid
solutions as range-based or range-free. In this paper we make this classification easy, where range-based
schemes and range-free schemes are divided into two types: fully schemes and hybrid schemes. Moreover,
we compare the most relevant localization algorithms and discuss the future research directions for
wireless sensor networks localization schemes.

Range Free Localization using Expected Hop Progress in Wireless Sensor NetworkAM Publications
Wireless sensor network (WSN) combines the concept of wireless network with sensors. Wireless Sensor Networks
have been proposed for a multitude of location-dependent applications. Localization (location estimation) capability is
essential in most wireless sensor network applications. In environmental monitoring applications such as animal habitat
monitoring, bush fire surveillance, water quality monitoring and precision agriculture, the measurement data are
meaningless without an accurate knowledge of the location from where the data are obtained. Finding position without the
aid of GPS in each node of an ad hoc network is important in cases where GPS is either not accessible, or not practical to use
due to power, form factor or line of sight conditions. So here we are going to used DV-Hop algorithm, i.e. distance vector
routing algorithm for finding the position of sensor. Here we summarizes the performance evaluation criteria of the
wireless sensor network and algorithms, classification methods, and highlights the principles and characteristics of the
algorithm and system representative of the field in recent years, and several algorithms simulation and analysis.

LOCALIZATION ALGORITHM USING VARYING SPEED MOBILE SINK FOR WIRELESS SENSOR NE...ijasuc
Localization of sensor nodes is important in many aspects in wireless sensor networks. The known
location of sensor node helps in determining the event of interest. A mobile sink is introduced to track the
event driven sensor nodes in the path of the event, thus conserving energy and time. We present a novel
range based localization algorithm which helps the mobile sink to compute the location of the sensor
nodes efficiently. The data transfer from the mobile sink and the sensor nodes is used to estimate the
sensor location. The sensor nodes do not need to spend energy on neighbouring interaction for
localization. The localization mechanism has been implemented in TOSSIM. The simulation results show
that our scheme performed better than other range-based schemes.

Integrated Security and Attack Detection Scheme for Wireless Sensor NetworksEditor IJMTER
The wireless sensor node is a tiny device that is used to capture environment information.
Sensor devices are used to capture temperature and pressure details from the environment. The
sensor devices are used in hospitals, home and production plants. The main components of a sensor
node are microcontroller, transceiver, external memory and power source. A wireless sensor network
(WSN) is a wireless network consisting of spatially distributed autonomous devices. Sensors are
used to cooperatively monitor physical or environmental conditions. Sensor network is equipped
with a radio transceiver or other wireless communications device. The sensor networks are deployed
with consideration of sensing and transmission coverage factors.
Sensor network security protocols provide confidentiality for the messages. Object location and data
sink information are the sensitive elements in the sensor network. Two techniques are used to
provide location privacy to monitored objects. They are Source-location privacy and Sink-location
privacy. Periodic collection and Source simulation models are used in Source-location privacy
technique. Sink simulation and backbone flooding models are used in Sink-location privacy
technique. Communication cost and latency factors are consider in the privacy protection model.
Source and destination location details are protected in the privacy model.
The proposed system integrates the location privacy and data security process for the wireless sensor
network. Region based query model is used to improve location privacy. Confidentiality and
integrity techniques are used for the security process. Rivest Cipher (RC4) algorithm and Secure
Hashing Algorithms (SHA) are used for the data security.

Data transmission occurs from transmitting node to sink node, which communicate each other via large number of intermediate nodes or directly to an external base station. A network consists of numbers of nodes with one as a source and one or more as a destination node.
A Fuzzy Based Priority Approach in Mobile Sensor Network CoverageIDES Editor
In this paper a new fuzzy based approach for
improving network coverage in wireless mobile sensor
networks is proposed. In the proposed approach firstly
each mobile sensor node determines its neighbors and its
distance from borders and obstacles. According to these
values, fuzzy inference engine calculates the priority of
node for movement. Then according to the priority, in
turn, nodes move away from each other to increase
coverage area in the target field. Simulation results show
that our fuzzy approach can reach higher degree of
coverage against other common approaches like FOA,
VEC and TRI algorithms.

Patient compliance: Challenges in management of cardiac diseases in Kuala Lum...pharmaindexing
Background
The objective of this study was to investigate the degree of compliance among cardiac patients who attend the health facilities in Kuala Lumpur and Perak, Malaysia. The reasons for non-compliance and recommendations from healthcare professionals were also evaluated.
Method
A cross-sectional study of 400 patients and 100 healthcare professionals was carried out. This study utilizes variables on external factors and internal factors as the measurement tools. The questionnaire which consists of Morisky self-reported medication adherence questions was administered to patients and causes for non-compliance sought. Questionnaire for healthcare professionals was used to determine strategies that can improve compliance rate.
Results
The study revealed a 15.8% of high adherence rate, 54.3% of moderate adherence rate and 30% of poor adherence to cardiovascular disease medications. The chi-square tests showed the strong association between dependent and independent variables. The model chosen for testing the patient compliance through external and internal factors gives an R2 value of 85.0% with an adjusted R2 of 84.7%. The F value (317.187) was also significant (p=0.000) which means that the variables have better fit in the multivariate model. The major reasons determined for non-adherence were attitudes and beliefs, lifestyle, side effects and cost of medications. The study recommends that pharmacists and dispensing technicians should be adequately qualified to provide proper counselling to cardiac patients on their medicines and disease conditions.
Conclusion
The result of this study is of value to health care providers. Compliance to cardiovascular medications will avoid treatment failures encountered in therapy.

The newborn health challenge faced by India is more formidable than that experienced by any other country in the world. The newborn health is inevitably affected by the traditional care practices of the mothers causing high infant morbidity and mortality.The aim of the study were determine the knowledge, attitude and practice of postnatal mothers regarding new born care and find out the association between knowledge, attitude and practice of postnatal mothers regarding new born care and to determine the association between these as well as with the selected demographic variables. A descriptive study was conducted to assess the knowledge, attitude and practice of postnatal mothers regarding new born care in selected maternity centres in Madurai. Survey approach was employed to select sample and it consisted of 100 postnatal mothers. Data was collected using structured interview schedule. Findings of the study showed that 65% of postnatal mothers had moderate knowledge; 61% had favourable attitude and 57% of them had high practice of new born care. There was a significant association between knowledge and attitude (r=+0.567), knowledge and practice (r=+0.388), attitude and practice (r=+0.321) .There was a significant association between knowledge and education, monthly family income and obstetrical score at p<0.05. Findings of the study indicated the need to conduct frequent assessment of knowledge, attitude and practice of postnatal mothers regarding new born care. Awareness and attitude of the mothers towards new born care still has lots of lacunae especially in those who belong to the lower socio economic statusand poorly educated postnatal mothers. So it is imperative to provide comprehensive training in the field of new born care for mothers during pregnancy
Late 19th century was evident of intelligent biomaterial; which has changed researcher’s perspective towards science and technology. This intelligent biomaterial are envisioned to have huge impact on Healthcare from sequential signalling of biomedical molecule, mimicking natural gene, an effective drug carrier, to high resolution diagnostic tool.From drug discovery aspect many of NCE fail to reach therapeutic potential due to PK/ PD profile. Nanotechnology has changed the face of drug discovery form chemical evaluation to structure of proteins in signalling pathways and development of chemical antibody. Nanotechnology from lab to market approval is long process due to regulatory evaluation. Though it seems to be bright future market it has to go through a long process from being innovation to complete market product. This makes whole process expensive making investor reluctant to invest in big projects.Western world is aware of dramatic potential of nano-projects; which has its limitation in financial investments; with major challenge of transforming nano science to commercial pharmaceutical product.

Antibiotic rationality and irrational prescribing was observed. The case study highlights the need of a clinical pharmacist in the health care team.
Corticosteroid induced disorders – An overviewpharmaindexing
Glucocorticoids are important in the treatment of many inflammatory, allergic, immunologic, and malignant disorders, and the toxicity of glucocorticoids is one of the commonest causes of iatrogenic illness associated with chronic inflammatory disease.Glucocorticoid-induced muscle atrophy is characterized by fast-twitch or type II muscle fiber atrophy. Corticosteroid (CS) therapy is widely used in the treatment of rheumatic diseases.Osteoporosis remains one of its major complications.Steroid induced glaucoma is a form of open angle glaucoma occurring as an adverse effect of corticosteroid therapy. Glucocorticoids induce hepatic and extrahepatic insulin resistance.Glucocorticoid treatment impairs both glucose transport in fat and muscle cells. Corticosteroid-induced psychosis represents a spectrum of psychological changes that can occur at any time during treatment. Cushing’s syndrome describes the signs and symptoms associated with prolonged exposure to inappropriately high levels of the hormone cortisol. Physicians must be aware of these adverse effects and be equipped to manage them.
Anti-inflammatory activity of pupalia lappacea L. Jusspharmaindexing
Pupalia lappacea (L) Juss is an erect shrub used in folklore medicine to treat bone fractures and in inflammatory conditions. Methanolic extract of aerial parts shown is claimed in traditional medicine that the leaves of the plant are used in the treatment of inflammation. In the present study, the methanolic extract of Pupalia lappacea was screened for its anti-inflammatory activity using carageenan induced rat paw edema egg white induced paw oedema models. The methanolic extract at the dose of 200 mg/kg p.o exhibited significant anti-inflammatory activity in carrageenan induced paw edema model (p<0.01). In egg white induced model, methanolic extract at the dose of 200 mg/kg inhibited paw oedema significantly (p<0.01) indicating that both test samples inhibit the increase in number of fibroblasts and synthesis of collagen and mucopolysaccharides during prostaglandin formation during the inflammation. These experimental results have established a pharmacological evidence for the folklore claim of the drug to be used as an anti inflammatory agent. HPTLC analysis of the extract shows the presence of gallic acid 1.24mg/ml, ferulic acid 2.00mg/ml, chlorogenic acid 46.25mg/ml and rutin 7.02mg/ml of the extract which were responsible for the claimed anti-inflammatory action in the animal models studied.
Lucinactant: A new solution in treating neonatal respiratory distress syndrom...pharmaindexing
Lucinactant is a novel synthetic surfactant, approved by the FDA on March 6th 2012, for use in treatment of RDS. It’s superiority as compared to the previously approved surfactants lie in containing sinapultide, a 21-amino acid peptide also known as KL4 peptide, which has been designed to mimic the activity of human surfactant protein. Lucinactant is completely devoid of any animal derived components. It is the fifth drug approved by the FDA for the treatment of RDS. It has shown immense efficacy in phase two clinical trials and animal model studies and exhibited better efficiency when compared to other surfactants in both 24 hour and two week mortality rates of infants in RDS. Lucinactant tends reduce the surface tension at the air-liquid interface of alveolar surfaces and allows lungs to function normally. It was observed that the side effects were lesser with Lucinactant when compared with other naturally derived surfactants.
Bioactivity screening of Soil bacteria against human pathogenspharmaindexing
Microorganisms have a profound effect on medical science as they not only infect & cause disease but also produce metabolic products that can cure infections. Soil happens to be a source for a variety of microorganisms. Most of the bacteria, particularly actinomycetes produce biologically active secondary metabolites. Though there are a number of antibiotics available, there is a pressing need for the discovery of new source for antimicrobials against the pathogens due to the development of drug resistance of the pathogenic microorganisms. In addition to, new pathogenic strains are also developing and causing infection to human beings. Bioactive compounds are compounds that are produced by any living organism and are known to exhibit various biological activities both in-vitro & in-vivo. Bioactivity may be antimicrobial, antineoplastic, anticancerous, immunomodulation, antifertility & others. Soil bacteria were isolated by standard technique and by making use of selective media. The isolates were identified and subjected for preliminary screening to look for their ability to produce bioactive materials. A total of 96 strains were isolated from three different soil samples. 14 of them were found to have antibacterial activity against the human pathogens like Staphylococcus aureus, Streptococcus faecalis, E.coli, Klebsiella aerogenes, Proteus vulgaris, Pseudomonas aureginosa and Salmonella typhi by preliminary screening. Further the selected (3) bacteria were grown in the suitable culture media for the production of bioactive metabolites by using rotary shake flask. The active metabolites was isolated by solvent extraction and concentrated by evaporation under reduced pressure. The antimicrobial screening of the active metabolites showed prominent effect against the clinical pathogens under the study.
A study on sigmoid Volvulus presentation and managementpharmaindexing
A study on sigmoid volvulus presentation and management was a 2yr retrospective study done at RMMCH.The diagnosis of sigmoid volvulus was made from a history of large bowel obstruction (constipation, abdominal distension, and abdominal pain), which were often recurrent and plain abdominal radiographs.The morbidity associated isSuperficial wound infection occurred in four patients. All the infected wounds eventually healed with conservative measures. Clinical anastomotic dehiscence was noted in 1 patient for which during relaparotomy proximal colostomy and mucous fistula was done. The mortality associated is shown is there were 9 deaths of which 7 were due to sepsis and 2 were due to comorbid illness. Two out of eight patients for whom a colopexy was done had a recurrent attack of sigmoid volvulus. The duration of hospital stay ranged between 10 and 21 days. Use of sigmoidoscopic detorsion for viable colon should be encouraged. Sigmoidopexy, which is associated with a recurrence rate of 20% in our series of patients, should be used selectively.Hartmann’s procedure is a safe option in sigmoid volvulus with gangrenous bowel.

Comparision of in vitro antibacterial activity of cefoperazone and levofloxac...pharmaindexing
Cefoperazone (a third generation cephalosporin) has effective in vitro activity against majority of pathogens. Levofloxacin (a flouroquinolone) is one which prescribed more due to its increased antibacterial activity against Gram-positive, Gram-negative, and atypical bacteria. Microbial resistance to antibiotics is now prevalent and poses a serious clinical threat. An attempt has been made to evaluate sensitivity of Cefoperazone and Levofloxacin against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhi. A total of 120 isolates were collected from different pathological laboratories and medical centers in Karachi, Pakistan. The above stated clinical isolates were extracted from urine/stool, skin, blood and sputum samples. Results show least resistance of Levofloxacin as compare to Cefoperazone against Escherichia coli (32.5% and 42.5%) and Pseudomonas aeruginosa (36% and 48%) while Staphylococcus aureus is still susceptible towards Cefoperazone and least sensitive to Levofloxacin by showing 26.6% and 50% resistance respectively. Study concluded that the prevalent pathogens are still susceptible towards Levofloxacin and Cefoperazone but the gradual increase in resistance is alarming to the general practice of prescribing antibiotic which require routine evaluation and surveillance to ensure the effectiveness of the antibacterial agents.
Concept of srotas from ayurvedic perspective with special reference to neurologypharmaindexing
Ayurveda is a life science. The researchers of ayurveda could rule out the presence of srotas (channels) spreading throughout the human body. These srotas (channels) are governed by vayu which is using all the srotas (channels) of the body to carry out the functional and physiological activities of the human body without which the human society will not exist. Several synonymous words have been described by the ayurvedicacharyas for srotas. Some are micro and some are macro in structures and they adopt the same colour of the particular dhatus of the body to which it belongs. The aim of the study is to justify that srotas are nothing but innurmerable channels or pathways of the nervous system governed by electric current without which no functional and physiological activities of the human body will develope.
Health promotion survey in overweight and obese students of universities in n...pharmaindexing
Introduction
Overweight and obesity is one of the major health problems in the UK and worldwide. Approximately two-thirds of the population in the UK is either overweight or obese. Overweight and obesity is an important issue that causes distress to most women. Health promotion is the best method to educate overweight and obese women. It is defined as the process enabling people to increase control over and to improve their health by Ottawa Charter for Health Promotion. It is aimed to enhance the well-being of the individuals and their positive attitudes towards prevention of various diseases. In order to make any improvement to the health promotion for overweight and obesity, the risk factors and the opinions from the public should first be identified and addressed.
Methods
Cross-sectional survey design was selected with a questionnaire that consisted of 20 open and close ended questions. A sample size of 196 was determined. The data thus gathered was analyzed using SPSS V20 (Statistical Package for Social Science version 20). Descriptive statistics (fx) and (SD) were used and Chi-square X2 test for association was employed.
Results
Out of the total 196 responses, only (40%) of the students had normal weight (SD 1.1), (25%) students had a good understanding of health promotion (SD 1.6), half (50%) appeared concerned about their weight (SD 0.5), (60%) had an obese family member (0.5). The BMI of students was associated with the presence of an obese member in their family and their weight as a concern for them. (P-value <0.05).
Conclusion
The health promotion service is beneficial as it was found to have raised concerns in the mind of the students regarding over weight and obesity. However it was observed that the understanding of health promotion service was different among students and this is the root of the problem.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

ABSTRACT
The knowledge of sensors’ locations is crucial information for many applications in Wireless Sensor
Networks (WSNs). When sensor nodes are deployed in hostile environments, the localization schemes are
vulnerable to various attacks, e.g., wormhole attack, pollution attack, range enlargement/reduction attack, and etc.
Therefore, sensors’ locations are not trustworthy and need to be verified before they can be used by location-based
applications. Previous verification schemes either require group-based deployment knowledge of the sensor field, or
depend on expensive or dedicated hardware, thus they cannot be used for low-cost sensor networks. In this paper,
we propose a lightweight location verification system that performs both “on-spot” and “in-region” location
verifications. The on-spot verification intends to verify whether the locations claimed by sensors are far from their
true spots beyond a certain distance. We propose two algorithms that detect abnormal locations by exploring the
inconsistencies between sensors’ claimed locations and their neighborhood observations. The in-region verification
verifies whether a sensor is inside an application-specific verification region. Compared to on-spot verification, the
in-region verification is tolerable to large errors as long as the locations of sensors don’t cause the application to
malfunction. To study how to derive the verification region for different applications and design a probabilistic
algorithm to compute in-region confidence for each sensor. Experiment results show that our on-spot and in-region
algorithms can verify sensors’ locations with high detection rate and low false positive rate. They are robust in the
presence of malicious attacks that are launched during the verification process. Moreover, compared with previous
verification schemes, our algorithms are effective and lightweight because they do not rely on the knowledge of
deployment of sensors, and they don’t require expensive or dedicated hardware, so our algorithms can be used in
any low-cost sensor networks.

I INTRODUCTION
Localization in wireless sensor networks, i.e.,
knowing the location of sensor nodes, is very important
for many applications such as environment monitoring,
target tracking, and geographical routing. Since
wireless sensor networks may be deployed in hostile
environment, sensors’ localization is subjected to many
malicious attacks. For example, attackers can
compromise sensors and inject false location
information. They can also interrupt signal transmission
between sensors and contaminate distance
measurements. Hence, the locations estimated in the
localization process are not always correct. Although
