    Aims: Plentiful mulberry varieties available in nature, they lack one or the other important economic trait required for silkworm Bombyx mori L. as food. Efforts have been made to induce phytomorphological variability in mulberry variety S54 using gamma rays. Experimental Design: RBD Method with three replications/treatment was followed. Place and Duration of Study: Mulberry garden, Department of Sericulture, Jnana Bharathi, Bangalore University and Mist chamber, Indian Institute of Horticultural Research (IIHR), Bangalore, Karnataka, India between 2006-2011. Methodology: Gamma ray (1kR-10Kr) was used to induce variability in juvenile twigs of mulberry for various agro-botanical characters viz., sprouting, rooting, internodal distance, leaf area, plant height etc. and leaves were subjected to biochemical analysis. Results: Mulberry variety S54 showed linear decrease in growth parameters with the increased gamma ray dosage and plants exhibited variability with increased rooting (81.33%), plant height (147.86cm) and leaf area (146.22cm2) when compared to control in M1 generation at 7kR. Mutants showing favourable characters were grown for M2 generation which exhibited marked improvement in growth and yield parameters. Biochemical constituents in S54 mutant leaves recorded at 7kR showed increased proteins, carbohydrate, chlorophyll a and b. Conclusion: Mulberry cuttings irradiated with gamma ray (7kR) exhibited favourable traits in rooting, plant height and leaf area over the control in M1 generation and mutants were grown for M2 generation and marked improvement in growth, yield and bio-chemical parameters were observe

    Two edible green leafy vegetables viz., Amaranthus (Amaranthus sp.) and Dill (Anethum graveolens) leaves collected randomly from three locations in Kolar district like Bethamangala, Bangarpet and K.G.F. are critically examined for heavy metal pollutants like Lead, Copper, Cadmium, Chromium and Zinc using Atomic Absorption Spectrophotometer. Results revealed that, Amaranthus and Dill leaves contain lead, copper, cadmium, chromium and zinc in all the sampling stations. Amaranthus leaves recorded significantly high lead concentration (41.57 ppm to 48.89 ppm) crossed permissible limits in all the stations. Copper concentration varied considerably in Bethamangala (4.26 ppm), Bangarpet (12.22 ppm) and KGF (21.59 ppm). Cadmium concentration at Bethamangala (2.06 ppm), Bangarpet (2.78 ppm) and KGF (2.96 ppm) recorded above permissible level. Chromium was detected in all the stations and values are not exceeding the permissible limit. Zinc concentration is higher in K.G.F (62.01 ppm) and in other two stations it is below the safe limit. Dill leaves showed high lead content (22.51 ppm-32.20 ppm) in three stations crossed safe value limit recommended by FAO/WHO. Copper concentration in Bethamangala (3.29 ppm), Bangarpet (12.22 ppm) and KGF (18.52 ppm) are in permissible limit. Cadmium content in Bethamangala (0.92 ppm) and Bangarpet (1.44 ppm) are below detection level and in KGF (2.32 ppm) exceeding the permissible limit. Chromium was detected in all three stations and values are below detection level. Zinc concentration is high in K.G.F (63.04 ppm) and in remaining two stations it is below the safe limit.

    Silkworm Bombyx mori L. is prone to be attacked by pathogen and more notably Beauveria bassiana L. Bed disinfectant Kavach was inoculated in different dosages (0.2%-1.6%) to IV and V instar silkworms of both bivoltine and cross breeds. Potency of disinfectant was assessed for the parameters such as survivability, larval duration, physiological, chemo and bio-assay tests. It was revealed that, bivoltine (NB4D2) silkworms were highly susceptible to diseases compared to cross breeds (PMxNB4D2). In bivoltine silkworms, survivability was found to be 61.15% at 1.6% of Kavach, when dusted twice during IV and V instar and crossbreed silkworms exhibited better resistance of 63.10% with the same treatments. Kavach treated silkworms showed decreased larval duration compared to control worms. Crossbreed silkworms were capable of maintaining high level of soluble proteins in spite of infection on 3rd day (17.40%), 4th day (20.50%) and 5th day (21.55%) whereas in bivoltine silkworms soluble protein level was brought down on 3rd day (19.30%), 4th day (22.40%) and 5th day (23.40%). Total soluble sugarsvaried from third day till fifth day in both the races. Kavach dusted twice at 1% proved to be very useful in the improvement of various commercial cocoons characters

    __Background:__ Drowning is a leading cause of injury-related mortality globally. Unintentional drowning (International Classification of Diseases (ICD) 10 codes W65-74 and ICD9 E910) is one of the 30 mutually exclusive and collectively exhaustive causes of injury-related mortality in the Global Burden of Disease (GBD) study. This study's objective is to describe unintentional drowning using GBD estimates from 1990 to 2017. __Methods:__ Unintentional drowning from GBD 2017 was estimated for cause-specific mortality and years of life lost (YLLs), age, sex, country, region, Socio-demographic Index (SDI) quintile, and trends from 1990 to 2017. GBD 2017 used standard GBD methods for estimating mortality from drowning. __Results:__ Globally, unintentional drowning mortality decreased by 44.5% between 1990 and 2017, from 531 956 (uncertainty interval (UI): 484 107 to 572 854) to 295 210 (284 493 to 306 187) deaths. Global age-standardised mortality rates decreased 57.4%, from 9.3 (8.5 to 10.0) in 1990 to 4.0 (3.8 to 4.1) per 100 000 per annum in 2017. Unintentional drowning-associated mortality was generally higher in children, males and in low-SDI to middle-SDI countries. China, India, Pakistan and Bangladesh accounted for 51.2% of all drowning deaths in 2017. Oceania was the region with the highest rate of age-standardised YLLs in 2017, with 45 434 (40 850 to 50 539) YLLs per 100 000 across both sexes. __Conclusions:__ There has been a decline in global drowning rates. This study shows that the decline was not consistent across countries. The results reinforce the need for continued and improved policy, prevention and research efforts, with a focus on low-and middle-income countries

    BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

    An authenticated encrypted routing protocol against attacks in mobile ad-hoc networks

    No full text
    Mobile Ad hoc Network is stated as a cluster that contains Digital data terminals and they are furnished with the wireless transceivers which are able to communicate with each other with no need of any fixed architecture or concentrated authority. Security is one of the major issues in MANETs because of vast applications such as Military Battlefields, emergency and rescue operations[10]. In order to provide anonymous communications and to identify the malicious nodes in MANETs, many authors have proposed different secure routing protocols but each protocol have their own advantages and disadvantages. In MANTE’s each and every node in the communicating network functions like router and transmits the packets among the networking nodes for the purpose of communication[11]. Sometimes nodes may be attacked by the malicious nodes or the legitimate node will be caught by foemen there by controlling and preventing the nodes to perform the assigned task or nodes may be corrupted due to loss of energy. So, due to these drawbacks securing the network under the presence of adversaries is an important thing. The existing protocols were designed with keeping anonymity and the identification of vicious nodes in the network as the main goal. For providing better security, the anonymity factors such as Unidentifiability and Unlinkability must be fully satisfied[1]. Many anonymous routing schemes that concentrate on achieving anonymity are proposed in the past decade and they provides the security at different levels and also provides the privacy protection that is of different cost. In this paper we consider a protocol called Authenticated Secure Routing Protocol proposed which provides both security & anonymity. Anonymity is achieved in this protocol using Group signature. Over all by using this protocol performance in terms of throughput as well as the packet dropping rate is good compared to the other living protocols
