Infections caused by fungal plant pathogens are recently recognized as a threat to food security worldwide and its control strategies need to be taken care where naturally synthesized fungicides such as those obtained from actinobacteria are becoming an area of great interest. A total of 68 isolates of actinobacteria were evaluated for their antagonistic potential against four fungal plant pathogens viz., Fusarium oxysporum CABI-293942, Fusarium udum MTCC-2755, Fusarium proliferatum MTCC-286 and Fusarium graminearum MTCC-1893 by dual culture assay. It was found that 83.8% of the isolates showed inhibitory activity against at least one of the tested plant pathogens with the percentage of inhibition ranging from 20–87.2. Thirteen Streptomyces isolates and one Nocardiposis isolate exhibited inhibition activity against all the tested pathogens. Overall, this study gives a basic understanding of the potential aspect of freshwater sediments derived actinobacteria against fungal phytopathogens.

Time difference of arrival (TDOA), a widely used passive target tracking technique, is used to derive the position of the target. By applying cross-correlation techniques on signals received by two different receivers one hyperbolic equation can be formed. With the help of a minimum four receiving stations, a unique intersecting point can be derived from hyperbolic equations which give the position of a target precisely. The accuracy of the target position depends upon the geometric location of the receivers with respect to the target location. A simulation study was carried out with seven numbers of a unique relation between target position measurement errors with the average range difference error is established. With the help of the above relation, receivers can be prioritized and four receivers could be placed in best geographical locations. By considering four high prioritized receivers minimum target position measurement error could be achieved. An attempt was focused to draw the error boundary, error factor of target position measurement with the range of the target. And it is clear that the error factor is varying linearly with the range of the target.

Indoor radon and thoron concentrations have been measured in the year 2015-2016 using the newly developed pin-hole based radon/thoron discriminating dosimeters with single entry. The measurements have been carried out in fifty dwellings of eight different villages/town situated in Saiha and Lawngtlai District, Mizoram. Dwellings were selected from the building type along with an idea of different ventilation conditions which affects the indoor concentration. Reinforce Cement Concrete (RCC) type of buildings are found to have the highest concentration of indoor radon (100.34 ± 7 Bq/m3) and thoron (41.41 ± 18 Bq/m3) and grounded house are found to have higher concentration compared to that of house with crawl space. However, the concentrations obtained in this work lies in the range covered by nationwide survey result as well as the ICRP regulations.

In recent years with increasing number of wireless devices Ad Hoc Networks become a vital technology. But these networks are highly vulnerable to attacks due to several reasons such as changing topology, open medium and lack of centralized monitoring. Current intrusion detection systems are based on either rule based or behavior model. The efficiency of such IDS is based on how accurate they identify the attacks. In clustering a cluster head is selected as coordinator for performing transmissions in both inter and intra cluster environment. There are many models for choosing a cluster head in Ad Hoc environment. However if the cluster head itself is a compromised node then the cluster head can launch attacks without being detected since its IDS is already malfunctioned. In this paper we propose an “Enhanced Cooperative Tamper Evident Agent Based Anomaly Intrusion Detection System”, which helps in identifying the attacks more accurately even if cluster head is compromised.

Temperature is one of the most important ecological factors which play a significant role on the earth, and all the living organisms have evolved various methods to meet extremes of temperature. Seasonal temperature variations are quite significant in freshwater lakes and ponds. The present study deals with the effect of seasonal variations of water temperature on different water quality parameters of Tamdil lake, Mizoram, India, for a period of two years, i.e., from March, 2014 to February, 2016. The water samples were collected from five sampling sites, and the average reading was calculated for each of the water quality attributes namely, temperature, pH, Dissolved Oxygen (DO) and Biological Oxygen Demand (BOD). The water samples were analyzed monthly, and the results are computed on seasonal basis, i.e., pre-monsoon, monsoon, post- monsoon and winter seasons. Statistically, there was a positive and significant relationship between water temperature and pH, and negative significant relationship between temperature and DO. A negative correlation was observed between temperature and BOD. The result shows that there is a significant seasonal variation in physico-chemical parameters. The lake has not reached the polluted stage yet.

PGP Rsare the rhizobacteria, playing an important role in plant growth and used in agriculture system either directly or indirectly as bio-fertilizers. Pseudomonas putida is used in the present study to inquire the effect of cytological as well as growth parameters on the coriander. A pot experiment was conducted to study the seed germination percentage and the Seed Vigor Index (SVI) of the coriander. The study showed the high percentage of seed germination and increase in shoot and root length of the young growing plant. Seed vigorousity was found more in treated plants with 889.7505 compared with non- treated plants (control) 213.8265. Some sprouted seeds were further used for cytological observation and found more cell division i.e. Active Mitotic Index % (AMI %) in cells treated with bacteria as 14.81% followed with control only 12.30%.

The study was conducted to assess the association of Arbuscular Mycorrhizal Fungi (AMF) in maize from three different jhum fallows. The jhum fallows are of three different years i.e., 1-3 years, 4-6 years and 7-10 years. Root samples were taken from maize to study colonization of AMF and spores were recovered from the rhizosphere region of the roots. It was observed that soil properties, rainfall pattern as well as human exploitation affect AMF colonization of roots.

A detailed survey was conducted on people living within and beyond 50m from mobile base station, on thirteen (13) different non-specific health symptoms faced by inhabitants living near mobile tower in six different localities in Champhai district for the first time, since mobile tower was erected in 2009. Power density of RF radiation have also been measured within and outside 50m from the station for GSM900 and GSM1800 in the same locality. The measured power densities have been compared with standard limits given by various scientific bodies like International Commission on Non-Ionizing Radiation Protection (ICNIRP 1998), Bioinitiative Report (Sage and Carpenter 2012) ,Salzburg Resolution (Haumann et al. 2000) and current Indian National Standards. The radiation level is under permissible limits as per the guidelines adopted in India. Also the results were statistically analysed and compared by using Kruskal Walli’s t-test. It was found that the comparisons are statistically significant with p<0.05 in all the six localities where headache, memory loss and muscle pain are the most common health complaints. From the correlation studies, it has been found that there is a strong positive correlation between power density and complaints on non-specific health symptoms.
