A Novel Approach for Remote Compilation using Docker Containers

The number of programming languages is getting more and more and developers are facing a tough time in installing all the compilers, libraries and supporting files for the development activities. Most of the time they want to experiment with new technologies, where the efforts required creating a complete environment to run the programs may not be feasible. On the other hand, several companies have started recruiting developers through their online programming platforms. In such situations, it is essential to protect the resources of the server from malicious programs written by the users by purpose or inadvertently. The client environment has to be as lighter as possible and the server environment must be as secure and efficient as possible. There are several existing solutions to meet this objective with plenty of demerits. In this paper we propose a novel method which overcomes most of the problems in the existing solutions and we have experimented the effectiveness of the proposed solution. In our proposed method we develop a docker based sandbox to run the client programs and display the output. We have developed a complete web interface to test the solution and created a backend to manage the users, sessions, tested programs and the outcomes which can be used for analytics too

Kernel Code for DNA Digital Data Storage

The biggest challenge when using DNA as a storage medium is maintaining its stability. The relative occurrence of Guanine (G) and Cytosine (C) is essential for the longevity of DNA. In addition to that, reverse complementary base pairs should not be present in the code. These challenges are overcome by a proper choice of group homomorphisms. Algorithms for storage and retrieval of information in DNA stings are written by using kernel code. Complexities of these algorithms are less compared to the existing algorithms. Construction procedures followed in this paper are capable of constructing codes of required sizes and Reverse complement distance.Comment: 12 pages, 1 figur

Efficacy of micro algae and cyanobacteria as a live feed for juveniles of shrimp Penaeus monodon

Growth performance and survival of giant tiger shrimp Penaeus monodon fed with five different micro algal diets as a live feed, was evaluated under laboratory condition. The experimental design consisted of feeding the juvenile with micro algal diets and cyanobacterial diets at the same concentrations. Fresh biomass of Chlorella sp., Tetraselmis sp., Isochrysis sp., Synechococcus sp. and Phormidium sp. were used as feed for shrimp P. monodon. Mean total length of shrimp was higher when fed with Chlorella sp. (4.8 cm) followed by Phormidium sp. (4.4 cm) and mean total weight was also higher in shrimp fed with Chlorella sp. (0.59 g) followed by Phormidium sp. (0.569 g). The survival rate of the shrimp was improved in shrimp fed Phormidium sp. (83.33%) and it was decreased in shrimp fed with Isochrysis sp. (36.67%). The shrimp that performed best had significantly more edible flesh (59.35%) (with Chlorella sp.) protein and lipid content (with Phormidium sp.) carbohydrate (with Tetraselmis sp.) Further more, water quality of the tank was better in shrimp fed with Chlorella sp. In general, the research of this study revealed that Chlorella sp. and Phormidium sp. could be used as a live feed for better growth of P. monodon.Key words: Penaeus monodon, micro algae, Synechococcus, Phormidium, Shrimp growth, Chlorella

Improvement of oil content in groundnut (Arachis hypogaea L.) by the impacts of gamma irradiation

Gamma radiation dosages of 100, 200, 300, 400, 500 and 600 Gy were given to the groundnut seed variety Dharani (Arachis hypogaea L.). The study's goal was to look at genetic diversity, heritability and genetic advancement for seed yield and quality characteristics in M2 generation using only a Randomized Complete Block Experiment using 3 replications from 2018 to 2019. The article's outcomes significantly enhanced the oil content of groundnut at 400 Gy to 52.44 % as compared to other dosages. For all characteristics, treated seeds displayed more variance than control seeds, particularly seed yield per plant showing the highest in GCV, PCV, H2, GA and GAM. In most traits, 400 Gy of gamma-ray treatment generates the largest changes however, 600 Gy of gamma-ray treatment also creates equivalent conditions. The link between features demonstrated that the number of pods per plant had a significant role in rationalizing seed yield variance in the M2 generation. These findings show that this yield component is one of the most important predictors of pod yield variations among plants and it is also favorably impacted by irradiation mutagens (gamma rays)

Cerebrospinal fluid lysozyme in the diagnosis of tuberculous meningitis

Pretreatment lysozyme levels in cerebrospinal fluid (CSF) were estimated in 37 patients with tuberculous meningitis (TBM), 16 with non-tuberculous meningitis (non-TBM) and 13 with non-inflammatory conditions of the central nervous system (controls) in an attempt to assess the role of CSF lysozyme in the diagnosis of TBM. Lysozyme content in the CSF was found to be elevated in all patients with bacteriologically confirmed TBM and in a large proportion of patients in whom the disease was clinically diagnosed but bacteriologically not confirmed. The enzyme was not detected in all but one of the control subjects and in most (69%) of the non-TBM patients

Response of biofertilizers, on the growth and yield of blackgram (Vigna mungo L.)

An experiment was conducted to determine the effect of biofertilizers on growth and yield of blackgram in field condition. The experiment was a randomized complete block design with five replication. The different inoculation (single and duel) of biofertilizers Azotobacter, Azospirillum, Rhizobium, phosphobacteria were incorporated into the top 15 cm of the soil. During the experiment period the plant samples were analysed, such as root length, shoot length, fresh and dry weight, leaf number, leaf area, root nodules and the biochemical content such as chlorophyll ‘a’, ‘b’, total chlorophyll, carotenoid, protein content, nodules and yield were analysed. The results revealed that addition the combination inoculation of Rhizobium + phosphobacteria significantly increased growth and yield of blackgram compared with control (without biofertilizers)

Growth and Biochemical Changes of Vegetable Seedlings Induced by Arbuscular mycorrhizal Fungus

Department of Botany, Annamalai University, Annamalai Nagar – 608 002ABSTRACT: The efforts were made to study the effects of Arbuscular Mycorrhizal fungi (AM) on the morphological and biochemical changes of four different vegetable seedlings grown under nursery conditions. The symbiotic association between AM fungi and plant roots provides a significant contribution to plant nutrition and growth. Hence, an attempt has been made to examine the effect of AM fungi on the four vegetable crops such as Tomato (Lycopersicum esculentum L.), Brinjal (Solanum melongena L.), Chilli (Capsicum annuum L.) and Bhendhi (Abelmoschus esculentus Moench.). The maximum increase in four plant’s morphological parameters like root length, shoot length, fresh weight, dry weight, number of leaves, total leaf area and biochemical parameters like chlorophylls, proteins and nutrient content of nitrogen, phosphorus and potassium were observed in AM fungi treated seedlings when compared to non-mycorrhizal seedlings (controlled). The sugar and starch contents showed decrease in mycorrhizal seedlings than non-mycorrhizal one. Key words: Glumus fasciculatum, Vegetables, Morphological parameters, Biochemical content Department of Botany, Annamalai University, Annamalai Nagar – 608 002M.
