    Abstract: A self-organized wireless communication short-lived network containing collection of mobile nodes is mobile ad hoc network (MANET). The mobile nodes communicate with each other by wireless radio links without the use of any pre-established fixed communication network infrastructure or centralized administration, such as base stations or access points, and with no human intervention. In addition, this network has potential applications in conference, disaster relief, and battlefield scenario, and have received important attention in current years. There is some security concern that increases fear of attacks on the mobile ad-hoc network. The mobility of the NODE in a MANET poses many security problems and vulnerable to different types of security attacks than conventional wired and wireless networks. The causes of these issues are due to their open medium, dynamic network topology, absence of central administration, distributed cooperation, constrained capability, and lack of clear line of defense. Without proper security, mobile hosts are easily captured, compromised, and attacked by malicious nodes. Malicious nodes behavior may deliberately disrupt the network so that the whole network will be suffering from packet losses. One of the major concerns in mobile ad-hoc networks is a traffic DoS attack in which the traffic is choked by the malicious node which denied network services for the user. Mobile ad-hoc networks must have a safe path for transmission and correspondence which is a serious testing and indispensable issue. So as to provide secure communication and transmission, the scientist worked explicitly on the security issues in versatile impromptu organizations and many secure directing conventions and security measures within the networks were proposed. The goal of the work is to study DoS attacks and how it can be detected in the network. Existing methodologies for finding a malicious node that causes traffic jamming is based on node’s retains value. The proposed approach finds a malicious node using reliability value determined by the broadcast reliability packet (RL Packet). In this approach at the initial level, every node has zero reliability value, specific time slice, and transmission starts with a packet termed as reliability packet, node who responded properly in specific time, increases its reliability value and those nodes who do not respond in a specific time decreases their reliability value and if it goes to less than zero then announced that it’s a malicious node. Reliability approach makes service availability and retransmission time.

    Abstract: A considerable progress in plant breeding for higher yield is attained mainly through selection of morpho-physiological attributes in rice. The field experiments were conducted at three different locations under sub-tropical conditions with four early maturing rice varieties viz., Binadhan-7, Binadhan-17, BRRI dhan33, and BRRI dhan39 during kharif-2 rice season (Aman; July-October) of 2016 to find out the natural variation in the morpho-physiological attributes contributing to  higher grain yield in rice. Morphological parameters on plant height, root structure, tillering ontogeny, internode elongation pattern, flag leaf length, flag leaf width, flag leaf angle, number of primary & secondary rachis, branches and also physiological traits on chlorophyll content, photosynthesis rate, total dry mass, growth rate, number of vascular bundles,  harvest index with yield and yield contributing characters were studied. Results indicated that plants having rapid growth and development at early growth stages showed  higher chlorophyll content, photosynthesis rate, long flag leaf, number of vascular bundles in 1st internode and also exhibited the increase in the number of grains per panicle resulting higher grain yield. Among the test varieties, Binadhan-17 showed superiority in the most morpho-physiological criteria and higher number of vascular bundles manifesting in higher grain yield. This information may help breeders to identity and develop high yielding rice variety.

    Abstract: An experiment was conducted at the Farmer’s Field, Boyra village, Mymensingh, Bangladesh during the period from February to May 2016 to study the yield performance of boro rice for seed production as influenced by nitrogen and phosphorus fertilization with different levels of roguing. The experiment comprised three levels of roguing viz. no roguing (R0), roguing one time (R1) and roguing two times (R2) and five doses of N and P fertilizers viz. Farmer practice (F1: 250 kg urea and 260 kg TSP), Optimum/recommended (F2: 187 kg urea and 200 kg TSP), High N (F3: 200 kg urea and 200 kg TSP), High P (F4: 187 kg urea and 240 kg TSP) and High N + High P (F5: 200 kg urea and 240 kg TSP). The experiment was laid out in a randomized complete block design with three replications. Results revealed that the Optimum doses of fertilizer applications significantly produced the highest grain yield among the treatments. All the yield contributing characters showed the best performance in this treatment. Though roguing did not produce significant yield variation but the interaction effects did. Here, The Optimum doses of fertilizer without roguing (F2R0) produced highest grain yield but it was at per with F3R1, F2R2, F2R1, F4R1 and F5R2 treatments. Among the five statistically alike treatments F2R2 i.e. optimum fertilizer dose with two rougings produced the highest number of filled grains per panicle and highest seed germination and appreciably higher percentage of pure seed. Based on this experimental result, it appears that optimum fertilizer dose with two times rouging treatment performed the best for seed production in BRRI dhan29.

    Abstract: A study was conducted to assess of groundwater and surface water quality of Barisal sadar upazila. Total 22 water samples (11 pond water and 11 groundwater) were collected from January to March, 2017. Samples were slightly acidic in nature and 7 pond water not suitable for aquaculture in respect of pH. Samples of pond were “excellent” and groundwater samples were “good” for irrigation except two high salinity group water for irrigation for EC. Calcium indicates the samples were suitable for aquaculture but 7 samples were not suitable due to higher Mg content. In respect of K, 9 samples were not suitable for aquaculture. Cu concentrations found suitable for all purposes. For Fe and Zn samples are suitable for irrigation and consumption. Chloride showed, samples were not suitable for livestock consumption except 7 ponds sample. Samples are not suitable for aquaculture in respect of Cl, Fe and Zn. For Manganese, samples (except 1) found suitable for consumption. Samples were “excellent” for sensitive, semi-tolerant and tolerant crops in respect of B. Not any samples responded to CO3 test and HCO3 concentrations found normal. All water sources free from Arsenic contamination. Phosphorus concentration in groundwater might not be harmful for multipurpose use. SAR categorized all samples “excellent” class for irrigation except 2 groundwater samples. 15 samples were “suitable”, 3 were “marginal” and 4 were “unsuitable” for irrigation in respect of RSC. For HT, 13 were “moderately hard” and 09 were “hard” limit for irrigation and samples were suitable for drinking and livestock consumption. Asian J. Med. Biol. Res. March 2020, 6(1): 44-55

    Abstract: In this research, we describe an augmented reality android-based idea in which we utilize augmented reality marker-based technology for augmenting newspaper advertisement with electronic information that does not modify the format of the newspaper document and remains exactly the same, substantially improves the utility of paper by reducing the portion of the printed Ad on the newspaper. An implementation on a camera phone is discussed that lets users retrieve data and access links from newspaper advertisements to electronic data. We carefully examined over twenty people of different ages and occupations who participated in the newspaper-based AR and we got a significant overall response. Further analysis implies that this may assist students in understanding the complex 3D objects, which they can manipulate, learn tasks and improve skills.

    Abstract: Boro rice (grown in winter under irrigated condition) contributes to the major portion of rice production (over 50%) in Bangladesh. Binadhan-17 is a green super rice developed by BINA which requires 30% less nitrogenous fertilizer and water which is grown in aman season (primely produced under rainfed). Due to it’s increasing popularity and adoption rice growers are keen to cultivate it in boro season also. Taking account of the above situation, two field trials were conducted at Magura during November 2019 to May 2020 to investigate the effect of variety, sowing dates and their interaction. Factorial RCBD (Randomized Complete Block Design) was applied for experimentation. Two rice varieties: Binadhan-17 (V1), BRRI dhan58 (V2) and three sowing times: 30th November (T1), 10th December (T2), 20th December (T3) were used as treatments. 35 days old seedlings were transplanted in main field. Relevant agronomic and morphological data were statistically analyzed through Statistix 10.0. Combined effect of the above factors at farm exposed that, T1×V1 required longest days (159.33 days) to mature. but, comparatively short life cycle (149.97 days) was observed by T3×V2. Maximum grain was yielded (7.70 t/ha) by T2×V1 and minimum (5.74 t/ha) by T1×V1 treatment combination. Outcomes of on station revealed that, T1×V1 needed more days (158.00 days) to mature; conversely, alike duration was noted with T2×V2 (147.20 days) and T3×V2 (145.43 days) which matured quite earlier. T2×V1 produced the highest grain yield (7.41 t/ha) and T1×V2 the lowest (5.94 t/ha). Our results indicate that, planting of Binadhan-17 on 10th December may give insect-disease free grains with optimum yield in context of Magura region. Farmers will be financially benefited if they cultivate this variety in the boro season in lieu of aman; due to higher yield
