The mobile adhoc network is a group of mobile nodes without having the fixed infrastructure. Due to the infrastructure less network and distributed nature, make mobile adhoc network susceptible to malicious attackers. So, we use an intrusion detection system called Enhanced Adaptive ACKnowledgement (EAACK) especially for mobile adhoc networks. Based on the digital signature algorithm (DSA) and RSA the EAACK is designed. To enhance the strength of the security in the mobile adhoc networks, we introduce an innovative approach called Hybrid Security Protocol that provides integrity, confidentiality and authentication. This Hybrid Security Protocol consists of Cryptography based on Elliptic curve, Dual-RSA algorithm and Message Digest MD5. Encryption is achieved by using Elliptic Curve Cryptography, Dual-RSA algorithm for authentication and MD-5 for integrity. By using a combination of both symmetric and asymmetric cryptographic techniques, we achieve better security with integrity.

International students are the bedrocks of the global higher education market. Thus, worldwide, higher education institutions (HEIs) focus most international marketing efforts on understanding the complexities surrounding this student market. Recent studies on international higher education reveal the choices made by this student cohort and a wide variety of factors influencing such selections. This present study focuses on a student decision that is made under a set of options. Using structural equation modelling (SEM), this study aims to investigate the relationships of economic factor and decision-making process with the choice of international academic destination. Results, conclusions, and recommendations are discussed.
Vending on the street is a worldwide fact and the most able to be seen component of the casual economy. Street vending, like other informal sectors, is characterised by low pay, ease of entrance, self-employment, and a huge number of individuals. Millions of individuals make a livelihood selling a variety of products and services on the street in cities and towns all over the globe. Despite the popular assumption that street selling would decline as the economy improves and wealth rises, it is on the rise in many areas. Because of their poor level of education and abilities, street sellers are often individuals who are not capable to get usual employment in the remunerative recognized sector. They attempt to address their financial issues by relying on their own limited financial resources. They are primary sharing route for a wide range of the daily-use goods, such as fruits, vegetables, ready-to-wear clothes, home appliances, stationery, toys, newspapers, magazines and shoes among others. If they be removed from the urban marketplaces, it would create serious problem for vegetable and fruit growers and small-scale businesses that couldn't afford to sell their goods via the formal sector's costly distribution networks. The significance of this industry can not be overstated, particularly given the government's inability to offer employment to India's millions of jobless and underemployed citizens. Even the corporate sector can only absorb a small part of our growing workforce. Overall, employment in the official sector is decreasing, leaving the majority of Indians to fend for themselves. If governments wish to decrease unemployment and poverty in our nation, they should support people in the informal sector to develop and thrive. They play an important part in the economic development and growth of local economy. Municipal authorities see street sellers as nuisances and the encroachers on sidewalks pavements and they are unappreciative of the important services that the street vendors offer to the world's common public. Vendors on the street offer essential services to urban people while surviving on their own business, limited resources, and labour. The state government and municipal authorities have been asked to provide security for street sellers so that they may make a living without fear.
Background: Exposure to cigarette smoke has been associated with pulmonary and reproductive dysfunctions; inflammatory response, oxidative stress and oxidative DNA damage induced by polycyclic aromatic hydrocarbons (PAHs) present in cigarette smoke have been implicated in the pathogenesis of these disorders. The peak expiratory flow rate (PEFR), a biomarker of inflammation and oxidative DNA damage (8-hydroxy-2-deoxyguanosine (8-OHdG), tumor necrosis factor alpha (TNF-α)), reproductive hormones (testosterone (TST), luteinizing hormone (LH), follicle stimulating hormone (FSH)) cotinine and urinary PAH metabolite (1- hydroxypyrene (1-HOP)) were estimated in male active smokers. Methods: One hundred men aged 20-47 years, comprising 50 active male smokers and 50 non-smokers, were randomly recruited into this comparative cross-sectional study. The PEFR was measured using a peak flow meter, serum levels of cotinine, FSH, LH, TST, TNF-α, and urine 8-OHdG by enzyme-linked immunosorbent assay and 1-HOP by high-performance liquid chromatography. Data analysis was done using a t-test and correlation analysis at p≤0.05. Results: Smokers had significantly higher cotinine (49.73±31.76 versus 0.51±0.69 ng/ml, p≤0.001), 8-OHdG (16.34±12.10 versus 5.79±2.14 ng/ml, p≤0.001) and lower PEFR (309.20±56.05 versus 452.80±45.76 L/min, p≤0.001) and LH (5.75±2.06 versus 6.97±2.79 mIU/ml, p=0.015) compared to non-smokers. Duration of exposure to cigarette smoke correlated positively with cotinine (r=0.937, p≤0.001) and 1-HOP (r=0.813, p≤0.001) while cotinine correlated positively with 1-HOP (r=0.863, p≤0.001) only in smokers. Conclusion: Reduced lung function and luteinizing hormone and concurrent increase in oxidative DNA damage associated with exposure to cigarette smoke may suggest the involvement of PAH-induced DNA damage in the development of pulmonary and reproductive impairment in smokers.

Influenza A virus presents a significant public health burden worldwide, with the 1918 Spanish flu pandemic being the most dramatic example. Swine influenza viruses can be transmitted to humans through occupational exposures and in live pig markets. Novel variants can emerge in pigs because they can be infected by human, avian and swine strains. This study was carried out to determine the seroprevalence and serotypes of swine influenza in pigs from a major slaughter slab in southern Kaduna. Using competitive ELISA and haemagglutination-inhibition (HI) assays, 305 swine sera were analysed. The result showed an overall seroprevalence of 28.20% (n=86), with H3N2 7.87% (n=24) emerging as the most dominant subtype in circulation. Concurrent antibody detection of H1N1 in 5.26% (n=16) was also detected in boar 2.62% (n=8) and sows 2.62% (n=8). This study revealed swine Influenza H1N1 and H3N2 serotypes are in circulation in pigs in Kaduna State, and that reassortment in the instance of co-infection of swine host is possible.
Currently, vehicle to vehicle communication is an important application and thrust area of research. In this paper the author highlighted the workings, executions, implementations and the application of the Internet of Things (IoT) in transport management and vehicle to vehicle communication systems. The main advantage of this Industry 4.0 based IoT technology is that it helps us to reduce road traffic and accidents. The limitations of GPS like accuracy, precision, effective analysis, etc. has led to the evolution of Mobile based V2V communication which is more effective, error proof, result oriented and smart. For proper analysis of traffic vehicle to vehicle communication is established. Random Data from vehicles taken by numerous sensors. Any car coming in its variety could effortlessly share the data by either of two cars nearby. With the help of vehicle to vehicle communication we can provide a path of emergency vehicles to reach the destination quickly. Based on the V2V application, Red and Green signals can be marked on the path as per traffic density and the emergency vehicle can take the shortest, fastest and low density route. Similar such examples are elaborated in the current research manuscript that will help the researcher in effectively finding the research gap for further advancement, analysis, innovation and optimization.
There has been an increasing awareness about the importance of herbal plants in therapeutic uses which are safe, efficient and induce little side effects This study was based on the evaluation of antibacterial activity of ethanolic extracts of the leaves of Oleaeuropaea (Olive tree) and Ficuscarica (Fig tree), alone and in combination, against enterococcus faecalis (E. faecalis) strain using well diffusion method and minimum inhibitory concentration. The results revealed that the Oleaeuropaea leave extract is more potent than the Ficuscarica leave extract against E. faecalis, as the zone of inhibition was 23 mm and 3 mm, respectively. By mixing both extracts, the results showed a slight synergistic effect, as the zones of inhibition were 20 mm, 24 mm, 24 mm and 25 mm for 1:1, 1:3, 1:6 and 1:9 ratios of the Oleaeuropaea leave and the Ficuscarica leave extracts, respectively. The minimum inhibitory concentration for E. faecalis growth was 200 mg/ml for the Oleaeuropaea leave alone, Ficuscarica and mixed with Ficuscarica. The present findings conclude a potent antibacterial activity of the olive and fig leave, and, their potential as a source of drug in the treatment of E. faecalis infections is suggested.

Background: Scabies is characterized by the presence of burrows, erythematous papules, and generalized pruritus which is usually worse at night. Recently an upsurge in the incidence of scabies has been reported in many settings, including the area of the study. The study aimed to determine if there is a nexus between scabies and climate change as a risk factor. Methods: This was a case-control study carried out in a Cottage Hospital. Case files of 18, 000 patients who attended the hospital between 2016 and 2019 were reviewed. The diagnosis was mainly clinical, i.e. based on the presence of itching in the typical scabies locations, presence of scabies burrows and history of similar itching in the other members of the patient’s household. 112 cases of scabies were diagnosed within this period. Results: From 2016 to 2019, the incidence of scabies rose from 3 to 50. Prevalence among males was 59.8%, and in females 40.2%, although the difference was not significant (p=0.0.53). Compared to other age groups, prevalence was highest in the 6-17 years age group (37.5%), but the difference among the age groups was also not significant (p=0.84). Conclusions: Within four years (2016-2019), the incidence of scabies had risen from 3 to 50 in the area of the study, being higher in males (59.8%) than females (40.2%), and in children less than 18 years (37.5%). Community survey, prompt diagnosis, adequate treatment and avoidance of overcrowding might help to stem the observed rising incidence of the disease.
Vitamin C causes a significant change in pharmacological effects of some drugs which may lead to unpredictable responses. Vitamin C-haloperidol interaction has not been confirmed in vivo. This study was aimed to investigate the influence of vitamin C on some pharmacological effects of haloperidol (extrapyramidal side effects caused by the antipsychotic haloperidol). Albino male mice (n = 24, body weight of 20 - 40 gm) were divided into four groups and each of consists of six mice. Group I (control): given 1% Tween 80 solution, group II: given vitamin C in a dose of 100 mg/kg, group III: given haloperidol (2 mg/kg), while group IV: given a combination of vitamin C and haloperidol. All the treatments were given by intraperitoneal route of administration. Three sub-acute doses of different treatments were given at 24:0, 5:0, 1:0 hour before scoring. Parameters scored were catalepsy, ptosis, rigidity and akinesia. The experiment was repeated using vitamin C in a dose of 500 mg/kg. Both doses of 100 and 500 mg/kg of vitamin C significantly antagonized the effect of haloperidol by decreasing all the tested parameters. The results indicate that vitamin C decreases extrapyramidal side effects caused by the antipsychotic haloperidol and show that it successfully decreases catalepsy, ptosis, rigidity and akinesia in mice.

To test and popularize the Krishi Vigyan Kendra, Barmer-II, Gudamalami, Rajasthan recommended Enhance the Productivity of Ridge gourd (Luffa acutangula L.) Cultivation in Net Trellis System in Barmer District of Rajasthan, On Farm Trials (OFT’s) were conducted during the kharif season of 2019 and 2020 in farmers participatory mode at three locations in Barmer District of Rajasthan. The experiment consisted of two treatments viz., recommended practice (Net trellis system) and farmers practice (Furrow). Net trellis system had significant increase number of picking (13), fruit length (43.33 cm) and fruit weight (210 g) as compared to farmer’s practice (07, 22.67 cm and 101.5 g) during both the year as well as pooled data. The two year average fruit yields of net trellis system have shown doubled production over farmers practice method. Net trellis system was recorded increase yield for 73.57% (138.06 t/ha) as compared to farmers practice (79.54 t/ha) during both the year as well as pooled data. Similarly, the net returns and B:C ratio also revealed that maximum under net trellis system during both the year as well as pooled data Rs 232790 per hectare and 3.36:1 as compared to farmers practice Rs 89913.5 per hectare and 2.30:1. Net trellis system had significant reduce the damage of pest and soil borne diseases and improve the quality of fruits
WhatsApp is mobile application which allows exchange of messages, videos, audio’s and images via Smartphone. The increased use of IM on phones has turned to be goldmine for mobile and computer age. This paper focuses on understanding experimental viewpoint about the intensity, usage of whatsapp messenger and its impact on the academic performance of students in institutions. Instead of fast communication and enhancing effective flow of information and idea sharing among students, whatsapp has actually impacted in some pessimistic performance of students. For instance it takes up much of the students study time resulting in procrastination related issues , destroys students’ linguistic skills, leads to lack of concentration during lectures, results in difficulty in balancing online activities (whatsapp) and intellectual preparation and distracts learner from completing their assignments and adhering to their private studies time table. It is very userfriendly and easy to get initiated. Simply enter the telephone number of the device into the app. It then sorts through the contacts (with your permission) on the phone to figure out who else also has the app already installed. Users can then invite more contacts or go ahead and start sending messages to the ones that the app discovered. Brian Acton and Jan Koum (2009) invented Whatsapp messenger for easy and fast communication and distribution of multimedia messaging. Whatsapp is one of the trend and fashion in technology that is commonly used on specific mobile phones and computers. Since the Smartphones became popular, many messaging services were launched but Whatsapp has become widespread among them. The service is available free for one year and later user has to pay very less annual amount. Besides all, this Application is highly fanatic and can create a great impact on regular users, and apart from that it can leave a trace that becomes difficult to control and cure. With whatsapp messenger, communication through mobile phones has become easier, faster and cheaper. It is less expensive as compared to the normal phone messaging. An individual can chat with friends and family overseas through whatsapp without having to incur global SMS charges.
Tobacco smoking negatively affects the quality of saliva and affects many biological parameters including salivary α-amylase enzyme activity. Salivary α-amylase enzyme is essential for the catabolism of carbohydrates. Forty- five healthy male volunteers aged between 18 and 69 years (40.0 ± 15.0) were divided into two groups, namely, the control group (n = 21) and the cigarette smoker group (n = 24). The effect of smoking on salivary α-amylase enzyme activity depends on the number of smoked cigarettes per day and the type of cigarettes as well as the period for how long the person smoking tobacco cigarettes was investigated. Different methods were used to analyze the activity of salivary α-amylase enzyme including the dinitrosalicylic acid method (standard colorimetric method). The results showed a significant increase (P < 0.05) in salivary α-amylase activity in Libyan smokers compared to the non-smokers in the morning and night, also, the findings showed a significant decline in salivary α-amylase activity during the increasing smoking period. The activity of salivary α-amylase in the young age smokers group increases in morning and night compared to the non-smokers group. There is no change in the activity of salivary α-amylase in the middle and older adult groups in the morning and night compared to young smokers group. In conclusion, smoking for a long period time more than 20 cigarettes per day decreases the activity of salivary α-amylase in Libyan subjects.

Medical research is defined as "all scholarly activities that deal with any of the areas of studies being conducted in the pre, para, and clinical areas being taught in a medical school". Such a definition is somewhat arbitrary, as medical research covers a much larger field and ultimately affects every individual. The results of research activities are directly translated into social action, such as pollution control, vaccinations, mass fluoridation and nutritional improvements. The eradication of diseases like smallpox, poliomyelitis and plague, the decline in the death rate from infectious and cardiovascular diseases, and the diagnosis of genetic disorders are some examples of how medical research helps to provide improved health care. Thus, the wealth of medical knowledge that grows through the process of discovery and research development becomes part of daily living. The aim of scientific research is always to extend the frontiers of knowledge and to discover rational correlations and principles [1, 2]. Medical research can be divided into biomedical (basic medical), clinical, and health science research. The areas overlap each other and health science research has a component of social research. Experimental research covers areas such as physiology, biochemistry, microbiology, pharmacology and pathology and is relatively easy to conduct. If adequate financial support is obtained, the necessary infrastructure for laboratory research could be built and experimental animals maintained in an animal house. For clinical research, the patients with a particular disease are the direct object of study. This type of research involves dealing with the clinical picture, diagnosis, therapy and prognosis of the disease. Dealing with human beings requires stringent regulations and precautions to be observed. It requires setting up a research team in the hospital to monitor and chart out guidelines involving the ethical dimension of the problem to be studied and maintain a systematic medical recording system. Moreover, it is through a prolonged study of a large number of cases of the same disease that clinical research learns to predict the likely prognosis and judge the efficacy of the treatment. This type of research activity has limitations in the form of having a restricted number of cases of the disease under investigation, a need to update one's knowledge concerning laboratory techniques from which he obtains his 'cues', and the longer time interval required to complete the work. Health science research is a recent development of medical research due to the demands placed on many health services. More often basic medical and clinical research go hand in hand and are inseparable. Furthermore, clinical research workers often conduct studies on experimental animals, due to either the limited number of human cases or for ethical considerations.

On-farm research was conducted at Gouripur sub-district under Mymensingh district of Bangladesh during the boro (mid November-June) season in 2013-14 and 2014-15 to evaluate the performance of non-puddled rice cultivation with and without crop residue retention. The rice var. BRRI dhan28 was transplanted by two tillage practices, viz., puddled conventional tillage (CT) and non-puddled strip tillage (ST) and at two levels of mustard residues, i.e., no-residue (R0) and 50% residue (R50). The experiment was designed in a randomized complete block design with four replications. There were no significant yield differences between tillage practices and residue levels in 2013-14. But in the following year, ST yielded 9% more grain compared to CT leading to 22% higher Benefit-Cost Ratio (BCR). Retention of 50% residue increased yield by 3% compared to no-residue, which contributed to 10% higher BCR. The ST combined with 50% residue retention yielded the highest grain yield (5.81 t ha-1) which contributed to fetch the highest BCR (1.06).
Background: Malaria is a systemic disease caused by various species of Plasmodium, transmitted through the bite of a female Anopheles mosquito. According to the World Health Organisation, there were 214 million cases of malaria worldwide in 2015. Nigeria’s burden of malaria is about 51million cases and 207,000 deaths annually, accounting for 60% of outpatient visits to hospitals, 11% of maternal mortality, and 30% of child mortality. The study aimed to compare RDT and microscopy in malaria diagnosis in a District Hospital in Enugu state, Southeast Nigeria. Methods: Blood samples of 300 suspected cases of acute malaria were tested for malaria parasite using RDT and microscopy simultaneously. Results: In 2017, the study found a malaria prevalence of 25% (46.2% in children, and 18.1% in adults) in Awgu. RDT was positive in 38% and microscopy in 70.3% of cases. Both RDT and microscopy were positive in 36.3%, negative in 28.3%, and discordant in 35.4%. Sensitivity of RDT was 50.7% (89.4% in children, and 25.6% in adults). RDT had a specificity of 100% (both children and adults), positive predictive value of 1 (both children and adults), and negative predictive value of 0.6 (0.5 in children, 0.6 in adults). Conclusions: RDT (SD Malaria Ag P. f) had more sensitivity in children (89.4%) than adults (25.6%), and the occurrence of false negative results was more in adults (46.8%) than children (9.5%). All negative RDT results need to be examined microscopically, to rule out false negative cases.
Background: E-waste, is the waste generated from used electrical and electronic devices that are no longer fit for their original intended use. Currently e-waste comprises more than 5% of total municipal waste flow, equivalent to 20-50 million tonnes annually worldwide. In 2014, Nigeria generated about 219 kilo tonnes of e-waste. The study aimed to increase public awareness on the need for proper management of e-waste because of its hazardous nature. Methods: This was a cross-sectional study in Enugu West Senatorial District of Enugu State comprising Oji-River, Ezeagu, Udi, Awgu and Aninri Local Government Areas with a population of 980,988. An adaptation of the UNEP, EMPA and Basel convention questionnaire, administered to 400 households was used for data collection. Results: The potential e-waste generation in the study area was 0.05 kg per inhabitant. 76% of the households were aware of the hazards of e-waste. 64% were willing to give out their e-waste to waste collectors. Only 26% of the e-waste were collected with the general waste. The correlation between awareness of the hazards of e-waste and willingness of the households to give out their e-waste was positive, moderate, and insignificant (r= 0.43, p=0.47). Conclusions: Although 76 per cent of the households were aware of the hazards of e-waste, with 64% willing to give out their e-waste, only 26% of the e-waste were eventually collected together with the general waste. There is a need to create a separate e-waste collection system.
Intensively cultivated rice-wheat cropping system of the Indo Gangetic plain (IGP) is a potential source of greenhouse gas (GHG) emissions.Agriculture sector emits GHGs like methane (CH4) and nitrous oxide (N2O). The total amount of GHGs emitted by a product is known as its carbon footprint (CFP).Quantification of CFP of crops will help in identifying management practices to reduce CFP of crop production. Studies related to assessing of CFP of agricultural products are lacking. The present review paper was aimed to discuss about the studies done on GHG emission from rice-wheat cropping system of the Indo Gangetic plains. The paper elaborates on what is CFP, how to calculate CFP of rice-wheat cropping system with the help of different case studies. The paper provides insights about certain agricultural management practices which can help in reducing CFP of rice-wheat cropping system. Discussion from this paper signifies the importance of carbon footprint assessment in maintaining the sustainability of rice wheat cropping system.
The latest phase of capitalist expansion is called “globalisation”. That no state is an autarky but enjoys comparative advantage over others with certain resources and that free trade among these states would work for mutual benefit is the essence of it. Consequently, it advocates the minimization of the governmental intervention in economic affairs and encourages free play of market forces to foster economic development. The argument that this rationale is also applicable to higher education is increasingly gaining currency. But this paper attempts to problematise such a proposition and in contrary argues that this may prove inimical to national development. Education and especially higher education is considered to be one of the factors that help state to promoting national development. However, apologists of globalisation call for its commercialization and argue for the “withdrawal of the state” from this realm. This has only resulted in mystifying profound class inequalities within and without state. Higher education in India is not immune to this ideology in the guise of good economics. It is being structured in such a fashion since 1991 that it has been primarily coupled with the process of economic liberalization and privatization. International financial institutions like World Bank, IMF, GATT, GATS, etc are its votaries. Education was acknowledged as one of the key sectors to be traded. As a result, higher education as a “social good” is fast shifting to being a commodity in the market.
