The mobile ad hoc network can form or destroy the network. Due to dynamic behavior of MANET there are different security and congestion issues in the network. At the point when the offered load on the system exceeds congestion happens, which prompts packet losses. There are such a large number of proposed conventions that are versatile to clog and deals with congestion. In this paper, we propose secure channel algorithm to prevent the network from congestion. The experimental analysis of the proposed algorithm is done using network simulator NS-2.34 and the comparative analysis of propose algorithm is done between performance measuring parameter PDR, routing load and throughput Keywords—Ad hoc network, Congestion, Network Simulator, PDR, Throughput.

The plant is a native of tropical America and naturalized in tropical Africa, Asia, and Australia. Local people known it as "Ghamara," in English popularly called "coat buttons" and is dispensed for "Bhringraj" by some of the practitioners of Ayurveda. The plant has many pharmacological applications such as hepatoprotective activity, anti-infl ammatory, wound healing, anti-diabetic activity, hypotensive effect, immunomodulating property, bronchial catarrh, dysentery, and diarrhea and to prevent falling of hair promotes the growth of hair, and antimicrobial activity against both Gram-positive and Gram-negative bacteria. The leaf juice possesses antiseptic, insecticidal and parasiticidal properties, as a remedy against conjunctivitis and is used also to check hemorrhage from cuts, bruises and wounds insect repellent. It is also used as biocarbon absorbent for removal of excess fl uoride. Hence, the present review aims to open new avenues for the improvement of medicinal use of T. procumbens for various ailments.

Saliva is important for oral and dental health, chewing sugar-free gums is a convenient way to increase salivary fl ow. Aim: To evaluate the effect of chewing sugar-free and sugar containing gums on dental plaque. Materials and Methods: A concurrent parallel randomized control trial was designed involving 20 subjects, divided into 2 groups of sugar containing and sugar free chewing gums, aged 20-25 years. The subjects were asked to chew one piece of chewing gum for 30 minutes 3 times a day after meal and to suspend all oral hygiene practices like brushing, mouth rinsing for 4 days. On day 5, subjects were scored for plaque using Silness and Loe plaque Index. The statistical analysis was performed using SPSS version 15. The comparison between groups was done using unpaired t-test, P value ≤ 0.05 were considered statistically signifi cant. Results: Sugar-free group had a lesser mean plaque score of 1.7 as compared to sugar containing group (2.4) this difference was statistically signifi cant (P ≤ 0.05). Conclusion: The sugar-free gums can be used as an adjunct to mechanical oral hygiene measures.

Yet, there does not yet exist a tool for simulating DNA sequencing data from such a nested sampling arrangement with single-cell and bulk samples so that developers of analysis methods can assess accuracy and precision. Results: We have developed a tool that simulates DNA sequencing data from hierarchically grouped (correlated) samples where each sample is designated bulk or single-cell. Our tool uses a simple configuration file to define the experimental arrangement and can be integrated into software pipelines for testing of variant callers or other genomic tools. Conclusions: The DNA sequencing data generated by our simulator is representative of real data and integrates seamlessly with standard downstream analysis tools.

However, it emerged from current literature that they are pleotropic in nature as they express a broad array of activities with potential therapeutic significance. These characteristics include, but are not limited to anticancer, antiviral, antitrypanosomal, antidiabetic adjuvants, anti-inflammatory, hepatoprotective etc. A structural classification of the bacterial metabolites has been given based on the structures re-drawn from the published data. Role of the structural motifs, thought to be primarily present in fungal and plant (eukaryotic) metabolites but now reported in bacterial metabolites as well, have been discussed in light of their multifaceted activities. An analysis of the current literature pertaining to diverse therapeutic properties of the bacterial metabolites is presented.

NS-2 is an open-source and very popular network simulation tool. It provides support for OSI or TCP/IP protocols stack and many standard routing and application protocols for wired and wireless networks. In NS2, many protocols have been implemented so far at the various layer of TCP/IP protocol suite to provide different functions, but none provides security functions. Although, some applications require security (Encryption/Decryption and key exchange) implementation in NS-2. However, NS-2 does not provide these features until now. In this paper, we solve this issue by adding a new security module or protocol in NS2. Security module helps us in key sharing as well as in the implementation of encryption/decryption functions. We analyze the features of a security module in details; discuss the algorithms used, simulation process and implementation of a security module based on NS2. Also, the simulation details of key sharing protocol and self-defined encryption/decryption protocol in a wired network are introduced. NAM is used to display the process of simulation. The purpose of the module is to introduce encryption/decryption features with key sharing into a network simulation program.
