Orthogonal Ramanujan Sums, its properties and Applications in Multiresolution Analysis

Signal processing community has recently shown interest in Ramanujan sums which was defined by S.Ramanujan in 1918. In this paper we have proposed Orthog- onal Ramanujan Sums (ORS) based on Ramanujan sums. In this paper we present two novel application of ORS. Firstly a new representation of a finite length signal is given using ORS which is defined as Orthogonal Ramanujan Periodic Transform.Secondly ORS has been applied to multiresolution analysis and it is shown that Haar transform is a spe- cial case

Removal of Cross Talk in Omega Switch Network by Using Improve Windowing Technique

An optical computer network is a network that relies primarily on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers. Such networks are useful for many purposes. Sharing content files (see file sharing) containing audio, video, data or anything in digital format is very common, and real time data, such as telephony traffic, is also passed using Optical technology. The proposed work is about to handle the network fault in case of cross talk in a switched network. In this work we are presenting the complete work with Omega Network. The work includes the analysis of existing methodologies to detect the confliction in cross talk. As the confliction is detected the next work is perform the talk with a smaller delay such that it will avoid the cross talk over the networ

Integrated Parametric Graph Closure and Branch-and-Cut Algorithm for Open Pit Mine Scheduling under Uncertainty

Open pit mine production scheduling is a computationally expensive large-scale mixed-integer linear programming problem. This research develops a computationally efficient algorithm to solve open pit production scheduling problems under uncertain geological parameters. The proposed solution approach for production scheduling is a two-stage process. The stochastic production scheduling problem is iteratively solved in the first stage after relaxing resource constraints using a parametric graph closure algorithm. Finally, the branch-and-cut algorithm is applied to respect the resource constraints, which might be violated during the first stage of the algorithm. Six small-scale production scheduling problems from iron and copper mines were used to validate the proposed stochastic production scheduling model. The results demonstrated that the proposed method could significantly improve the computational time with a reasonable optimality gap (the maximum gap is 4%). In addition, the proposed stochastic method is tested using industrial-scale copper data and compared with its deterministic model. The results show that the net present value for the stochastic model improved by 6% compared to the deterministic model

Diversity rich solutions

Every household is diverse and diversity can be observed within household in terms of crops, varieties and landraces, soil type, food preferences and preparation methods, knowledge and practices related with production management of agrobiodiversity and other genetic resources. Farmers are practicing agricultural practices that promotes the use of diversity such as growing mixture of landraces, composting, fertigation. Modern agriculture focuses on developing large scale uniform technology eg use of urea, mono-genotype variety. Such system puts pressure and disturbs the ecological balance causing high risk for crop failure and genetic erosion. Any technological option with greater diversity is less risky, more sustainable and higher adaptability in agriculture. Diversity rich solution is any technology or problem associated solution that considers diversity as an option and address problems with inter and intra level diversity as well as combinations of different components. it also includes multiple technology for a single problem. Some examples are broad genetic base variety, cultivar mixtures, compost (made from different species), biopesticide (made from different species), etc. Diversity rich solution is in practice since 2014 in Nepal with the objective of conserving agrobiodiversity, promoting ecologically oriented sustainable agriculture that also enhances ecosystem services

Synthesis and characterization of some ethoxyphthalimide substituted triazole derivatives assembled with pyridine and thiazolidinone heterocycles

Novel 2-(4-substitutedphenyl)-3-{3-[(S-ethoxyphthalimido)sulfanyl]-5-pyridin-4-yl-4H-1,2,4-triazol-4-yl}-1,3-thiazolidin-4-ones (6a-d) were synthesized via a multistep reaction sequence, using isoniazid (isonicotinic acid hydrazide) as starting material. The structures of the synthesized compounds were assigned on the basis of elemental analysis, IR and 1H NMR spectral data

Good practices for agrobiodiversity management

Native agricultural genetic resources have been generally under-valued, therefore, some initiatives have been taken through Global In-situ agrobiodiversity project joinly implemented by NARC, LI-BIRD and Bioversity International since 1997 in Nepal for conservation and sustainable use of agrobiodiversity on-farm. Global in-situ project (1997-2006) has developed many good practices for agrobiodiversity management which are published in On-farm Management of Agricultural Biodiversity in Nepal: Good Practices 2006 (B Sthapit, P Shrestha and M Upadyay, eds). A good practice is a process or methodology or action that is effective and successful; environmentally, economically and socially sustainable; technically feasible; inherently participatory; replicable and adaptable, that has been proven to work well and produce good results. It is a successful experience tested and validated in achieving its objective. For further widening the scope of good practices in the country, NAGRC, LI-BIRD and Bioversity International have generated, tested and adapted a number of good practices in four sites, Jungu, Dolakha; Ghapanpokhara, Lamjung; Hanku, Jumla; and Chippra, Humla through a project Integrating Traditional Crop Genetic Diversity into Technology: Using a Biodiversity Portfolio Approach to Buffer against Unpredictable Environmental Change in the Nepal Himalayas , commonly called as Local Crop Project (LCP) from 2014 to 2019. Good practices listed here are well tested and adapted by the communtiies in the fields, shown their positive impact, shared and discussed among the relevant stakholders. Project team have tested and validated many good practices, however, we have included 22 good practices that are worth sharing for its dessimination and mainstreaming. These practices, though specially based on eight crops (rice, bean, barley, foxtail millet, proso millet, amaranth and buckwheat), can be widely applicable to other agricultural genetic ressources in different locations, national and globally

Geographical indication

Agricultural products are generally associated with their place of production and are influenced by specific local, geographical factors such as climate and soil. A geographical indication (GI) is a sign (or name) used on products that have a specific geographical origin and possess unique qualities or a reputation associated with the product of the origin (WIPO 2004). The qualities, characteristics or reputation of the product should be essentially due to the place of origin. GI is an intellectual property that protects the product of the area and ultimately helps to promote conservation of agrobiodiversity on-farm and boost economy of local community. The well-known examples of GIs in South Asia include Darjeeling tea, Basmati rice, Himalayan water, Alphonso and Sindhri mangoes, Bhutanese red rice, Pakistani shu (wind proof woolen fabric) and Ajrak (designs from Sindh), jasmine (Hom Mali) rice. Until now, there is no any GI protected products in Nepal. Government of Nepal has approved the National Intellectual Property Right Policy (2017) which includes Copyrights, Patents, Industrial design, Trademarks, GI, Varietal protection, Trade secrets and Traditional knowledge policy (MoICS 2017). Among these policies, GI gives exclusive right to a region or a landscape (eg village, town, region or country) to use a name for a particular product with certain characteristics that corresponds to their specific location. There are more than 100 agricultural products (Joshi et al 2017) which have already established their reputation representing their GIs. Malla and Shakya (2004) have identified and listed 87 potential products for geographical indication (GI) protection in Nepal. Most of the products possess greater cultural and age-old traditional values. Important indigenous crop landraces and their products linked with particular geography, which should therefore, be protected with GI by developing suitable legislation for their market promotion, on-farm conservation and livelihood enhancement of local communities. For GI promotion, Geo-linked popular crop landraces and their traits need to be found out for their potential trade promotion and value addition

DEVELOPMENT AND VALIDATION OF RP-HPLC METHOD FOR SIMULTANEOUS ESTIMATION OF THREE-COMPONENT IN TABLET DOSAGE FORMULATION

ABSTRACT:An accurate, simple, reproducible andsensitive method for the determination ofparacetamol, caffeine and chlorpheniraminemaleate in tablet dosage form is developed andvalidated. The separation is achieved usingHiQsilC18HS reverse-phase column (250 X 4.6mm I.D., particle size 5μm) using a mixture ofacetonitrile and water in the proportion 55:300with final pH of 2.4 adjusted with o-phosphoricacid as a mobile phase. The flow rate is 1.0mL/ min and effluents were monitored at 265nm. Total run time is less than 12 min. andretention time of paracetamol, caffeine andchlorpheniramine maleate are 6.742, 9.417, and3.683 min respectively. Validation of method isdone as per ICH guideline for accuracy,precision, linearity, specificity, and sensitivity.The linearity for paracetamol is found to be100-650 μg/mL where as for caffeine andchlorpheniramine maleate is found in the rangeof 15-100 μg/mL. Result of validation study isfound statistically significant because all thestatistical parameters were within theacceptance range (COV and S.D. <1.0 for bothaccuracy and precision). The limits of detection(LOD) values are 1.2014, 0.4587 and 0.8945and limit of quantitation (LOQ) values are0.5142, 0.4512 and 0.7845 μg/mL forparacetamol, caffeine and chlorpheniraminemaleate respectively. High percentage recoveryand low COV value revealed the reliability ofthe method for quantitative study of threedrugs in Fevril tablets as a quality-control toolfor routine quantitative determination ofparacetamol, caffeine and chlorpheniraminemaleate

Diversity analysis of Sweet Potato (Ipomoea batatas[L.] Lam) genotypes using morphological, biochemical and molecular markers

276-285Sweet potato [Ipomeabatatas(L.) Lam.]is a nutritious food crop primarily grown by small and marginal farmers. Successful breeding and germplasm conservation programs demands characterization of its germplasm. Here, we tried to determine genetic diversity among 21 sweet potato genotypes using morphological, biochemical and molecular markers. Ten morphological traits were studied and subjected to analysis of variance (ANOVA). Mean square due to germplasm were highly significant as well as wide mean range performance was observed for tuber number per plant, individual tuber weight, tuber fresh yield per plant, tuber dry yield per plant, tuber yield per plot and tuber length. UPGMA (Unweighted Pair Group Method Arithmetic Average) cluster analysis based on morphological traits separated the germplasm into three groups. The genotypes Gautam, Shree Arun, RS-92 and CO-3-4 appeared promising with regard to yield characters. Total phenol was maximum in in V-12 genotype (1.39 mg), while minimum was recorded in Samrat genotype (0.95 mg). The highest total antioxidant was observed in the genotype Samrat (0.30 mg), while minimum was recorded in the genotype Navsari Local (0.16 mg). Molecular diversity analysis was carried out using 25 RAPD (Random Amplified Polymorphic DNA) primers, out of which 13 primers produced 117 reproducible amplicons (106 polymorphic, 7 monomorphic and 4 unique amplicons). UPGMA dendogram based on RAPD data separated the genotypes into two major clusters having the similarity coefficient ranged from 0.56 to 0.76. The results can be used for sweet potato crop improvement through molecular breeding and marker assisted selection of for desired traits in future
