First results from the CAWSES-India Tidal Campaign

The first CAWSES-India Tidal Campaign was conducted by the Indian scientific community during March–April 2006. The objectives of this campaign were: (1) To determine the characteristics of tides in the troposphere and lower stratosphere (0–20 km) and mesosphere and lower thermosphere (MLT) region (80–100 km), (2) to explore and identify what lower atmospheric processes drive middle atmospheric tides in the Indian continental region and (3) to provide information on those short-term variabilities of MLT tides that are likely to have an impact on the ionospheric variabilities and contribute to the upper atmospheric weather. Data sets from experiments conducted at the three low latitude radar sites, namely, Trivandrum (8.5° N, 76.9° E), Tirunelveli (8.7° N, 77.8° E) and Gadanki (13.5° N, 79.2° E) and fortnightly rocket launches from Thumba were made use of in this study. An important observational finding reported in this work is that the radar observations at Tirunelveli/Trivandrum indicate the presence of 15–20 day modulation of diurnal tide activity at MLT heights during the February–March period. A similar variation in the OLR fields in the western Pacific (120–160° longitude region) suggests a possible link between the observed tidal variabilities and the variations in the deep tropical convection through the nonmigrating tides it generates

ONEChat: Enabling Group Chat and Messaging in Opportunistic Networks

Opportunistic networks, which are wireless network "islands" formed when transient and highly mobile nodes meet for a short period of time, are becoming commonplace as wireless devices become more and more popular. It is thus imperative to develop communication tools and applications that work well in opportunistic networks. In particular, group chat and instant messaging applications are particularly lacking for such opportunistic networks today. In this paper, we present ONEChat, a group chat and instant messaging program that works in such opportunistic networks. ONEChat uses message multicasting on top of service discovery protocols in order to support group chat and reduce bandwidth consumption in opportunistic networks. ONEChat does not require any pre-configuration, a fixed network infrastructure or a client-server architecture in order to operate. In addition, it supports features such as group chat, private rooms, line-by-line or character-by-character messaging, file transfer, etc. We also present our quantitative analysis of ONEChat, which we believe indicates that the ONEChat architecture is an efficient group collaboration platform for opportunistic networks

Ascitic Fluid Adenosine Deaminase Activity - A Non Invasive Diagnostic Test for Tuberculous Ascites.

INTRODUCTION : Tuberculosis has been declared a global emergency by the World Health Organization and is the most important communicable disease worldwide. The prevalence of extra-pulmonary tuberculosis seems to be rising, particularly due to increasing prevalence of acquired immunodeficiency syndrome (AIDS). In patients with extra pulmonary tuberculosis, abdomen is involved in 11% of patients. Though potentially curable, abdominal tuberculosis continues to be a major cause of morbidity and mortality in India. In the abdomen, tuberculosis may affect the gastrointestinal tract, peritoneum, lymph nodes, and solid viscera. The disease can mimic various other gastrointestinal disorders, particularly inflammatory bowel disease, colonic malignancy, or other gastrointestinal infections. Because of the non-specific symptoms and signs, its diagnosis is often delayed. Autopsies conducted on patients with pulmonary tuberculosis before the era of effective antitubercular drugs revealed intestinal involvement in 55-90 per cent cases, with the frequency related to the extent of pulmonary involvement. About 0.4 million people in India are co-infected with HIV and tuberculosis. Extra- pulmonary forms of tuberculosis which account for 10-15 per cent of all cases may represent up to 50 per cent of patients with AIDS. Tuberculosis of the gastrointestinal tract is the sixth most frequent form of extra-pulmonary site, after lymphatic, genitourinary, bone and joint, miliary and meningeal tuberculosis. Adenosine deaminase (ADA) activity in ascitic fluid is a sensitive and specific marker for tuberculosis. Adenosine deaminase (ADA) is an enzyme widely distributed in mammalian tissues, particularly in T lymphocytes. Increased levels of ADA are found in various forms of tuberculosis making it a marker for the same. The sensitivity and sensitivity of ADA activity are 95 and 98 per cent respectively. In low protein ascites, false negative results are more frequent. In patients with HIV infection and tuberculous ascites, ADA levels may be lower. ADA is particularly useful in developing countries where more sophisticated and expensive tests such as laparoscopy may not be available. AIM OF THE STUDY : The study was conducted with the objective of (i) Evaluating the efficacy of ascitic fluid adenosine deaminase activity in diagnosing tuberculous ascites. (ii) The efficacy of ascitic fluid adenosine deaminase activity in differentiating tuberculous from non-tuberculous ascites. CONCLUSION : In conclusion, measurement of Adenosine deaminase activity (ADA) level in ascitic fluid is a fast and accurate test for diagnosing peritoneal tuberculosis. It has enough discriminatory power to either confirm or rule out the diagnosis of peritoneal tuberculosis in most cases. The beginning of empirical treatment when a patient has a high ADA value in ascitic fluid seems to be a good approach while waiting for the results of mycobacterial cultures or biopsies. However in the presence of cirrhosis, the sensitivity and specificity of adenosine deaminase in confirming peritoneal tuberculosis is low. Ascitic fluid adenosine deaminase can be used as a diagnostic test in centers where laparoscopy is not available. It can also be used in very sick patients who are unfit for laparoscopy. For differentiating tuberculous ascites from non-tuberculous ascites, the optimal cut off value for asctic fluid adenosine-deaminase is 35 U/ L

The efficacy of statins as otoprotective agents: A systematic review

Objective: This systematic review examined the current literature, summarized research findings and identified research gaps regarding the efficacy of statins on audiological outcomes. Methods: Systematic search of electronic databases and grey literature was performed. Eligibility criteria was the study of a statin drug with report of audiological outcomes such as hearing, tinnitus, or balance in either human or animal studies. Data extraction and quality assessment were performed by two independently researchers. The characteristics of the study and research findings were collated and summarized. A narrative synthesis was conducted. Meta-analysis was not possible due to heterogeneity of the included studies.Results: Analysis of searches yielded 17 studies meeting the criteria. Included studies had variable drug type and dosage, outcome measures, and associated inner ear conditions. Most animal experiments showed promising audiological outcomes after statin treatment, demonstrated by the results of auditory brain stem response, distortion product otoacoustic emissions, and inner ear histology. However, no clear effect can be discerned in human trials due to the mixed results, and heterogeneity in research methodology and quality. Audiological outcomes were not always correlated with cholesterol levels. Conclusions: Statins remain a potential candidate as otoprotective agents which warrant further investigation

Measurements of Multicast Service Discovery in a Campus

Applications utilizing multicast service discovery protocols, such as iTunes, have become increasingly popular. However, multicast service discovery protocols are considered to generate network traffic overhead, especially in a wireless network. Therefore, it becomes important to evaluate the traffic and overhead caused by multicast service discovery packets in real-world networks. We measure and analyze the traffic of one of the mostly deployed multicast service discovery protocols, multicast DNS (mDNS) service discovery, in a campus wireless network that forms a single multicast domain of large users. We also analyze different service discovery models in terms of packet overhead and service discovery delay under different network sizes and churn rates. Our measurement shows that mDNS traffic consumes about 13 percent of the total bandwidth

Accelerating Service Discovery in Ad-Hoc Zero Configuration Networking

Zero Configuration Networking (Zeroconf) assigns IP addresses and host names, and discovers service without a central server. Zeroconf can be used in wireless mobile ad-hoc networks which are based on IEEE 802.11 and IP. However, Zeroconf has problems in mobile ad-hoc networks as it cannot detect changes in the network topology. In highly mobile networks, Zeroconf causes network overhead while discovering new services. In this paper, we propose an algorithm to accelerate service discovery for mobile ad-hoc networks. Our algorithm involves the monitoring of network interface changes that occur when a device with IEEE 802.11 enabled joins a new network area. This algorithm allows users to discover network topology changes and new services in real-time while minimizing network overhead
