Collective Signature Schemes Using Problem of Finding Roots Modulo
No full textDigital signature schemes in general and representative collective digital signature schemes, in particular, are often built based on the difficulty of the discrete logarithm problem on the finite field, of the discrete logarithm problem of the elliptic curve, of the problem of factor analysis, of the problem of finding the roots modulo of large primes or a combination of the difficult problems mentioned above. In this paper, we use the new difficult problem, which is to find the with root in the finite ground field GF(p) to build representative collective signature schemes, but the chosen modulo p has a special structure distinct p=Nt_0 t_1 t_2+1, where N is an even number and t0, t1, t2 are prime numbers of equal magnitude, about 80 bits. The characteristics of the proposed scheme are: i) The private key of each signer consists of 2 components (K_1, K_2), randomly selected, but the public key has only one component (Y) calculated by the formula Y= K_1^ (w_1) K_2^ (w_2); w_1 = t_0 t_1 and w_2 = t_0 t_2; and ii) The generated signature consists of a set of 3 components (e, S1, S2). We use the technique of hiding the signer's public key Y, which is the coefficient λ generated by the group manager, in the process of forming the group signature and representative collective signature to enhance the privacy of all members of the signing collective
Eco-friendly Sustainable Multiphase Polymer Systems for Advanced Functions
No full textWhen Eric Fawcett and Reginald Gibson discovered polyethylene accidentally, they never realized how useful their discovery will be for mankind, similar to how Charles Goodyear’s idea of adding sulphur to polyisoprene would revolutionize the tire and other rubber industries. Although those discoveries centuries ago have never realized their current impact, however, the fact is undeniable on how polymer science has conquered the world, gaining an irreplaceable position from a utilitarian perspective

Design of Digital Solar Water Pump Using Microcontroller ATmega 32
No full textThis paper focuses on the application of solar energy along with microcontrollers to design and run a motor to pump water from various sources. The solar water pump is one of the applications or appliance that perform task with the use of solar radiation. The solar water pump consists of solar PV array, solar pump, inverter, AC water pumping device etc. Solar energy radiation is converted in electrical current or power source which is then used to run a pump and draw water directly from ground, wells, rivers, lakes etc. In this paper, the relationship between flow rate of the water and luminous intensity of the solar irradiance is studied and the data are linearly fitted to find out the correlation between these parameters. Also the study about efficiency of the solar powered water pump shows that the operation of this type of pumping system is quite efficient than other types of fossil fuel engines like diesel, petrol, kerosene etc. in long run. The use of Arduino Uno, flow sensor, LDR sensors in the solar powered water pump helps to analyze the relation between these parameters and know the conditions favorable for excess supply of water in short time efficiently. These solar powered devices are the future of clean and green future of this world. Thus it is not only necessary but also compulsory to enhance the usage of solar energy throughout the globe

No full textPresent review article explains the dietary and nutritional value of various fish derived natural food products. Fish is a good source of important nutrients such as proteins, fats, vitamins and minerals. Fish oil contains polyunsaturated fatty acids (PUFAs) mainly omega-3 fatty acids, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and eicosanoids. Fish contains high-quality protein ( ~ 14-16 percent) and is consumed worldwide. This article also emphasizes therapeutic uses of fish nutrients and oil in healing of wounds, hyper pigmentation, dermatitis, and in cardiovascular risks. Fish oil polyunsaturated fatty acids (PUFAs) are highly beneficial in cardiovascular problems and dermatitis. Fish oil is good for skin-related diseases such as photo-ageing and melanogenesis These also affect anticancer, wound healing and anti-depressant activity. In the present review various local, national, and international processed fish derived food currently available in the market fish dishes have been mentioned
Anti-trypanosomal Activity of Bufonidae (Toad) Venom Crude Extract on Trypanosoma brucei brucei in Swiss Mice
No full textTrypanosomiasis afflicts about 6 ~ 7 million people globally and to a large extent impedes livestock production in Africa. Naturally, trypanosomal parasites undergo genetic mutation and have developed resistance over a wide range of therapies. The utilization of animals and plants products has presented therapeutic potential for identifying novel anti-trypanosomal drugs. This study evaluated toad venom for anti-trypanosomal potency invivo in Swiss mice. Toads were collected from July to August 2019. The acute oral toxicity and biochemical characterization of the toad venom were determined. The experimental mice were administered various doses (130 mg/kg, 173 mg/kg and 217 mg/kg) of the toad venom crude extract and 0.75 mg/mL of Diamizan Plus standard drug for the treatment of trypanosomiasis, once daily for 3 days. The in-vivo anti-trypanosomal activity was evaluated by a curative test, after infecting the mice with Trypanosoma brucei brucei. The pre-patent period was 72 hours before treatment commenced. The overall results showed that trypanosomal load was highest in the control group while the group treated with Diamizan drug had the least trypanosomal load. As such, the mean trypanosomal load in relation to treatments showed a very high significant difference (P<0.05). Also, the mean trypanosomal load in Swiss mice in relation to the highest dosage of toad venom versus Diamizan drug showed a very high significant difference (P<0.05). The mean change in relation to the haematological parameters across treatments groups varied significantly (P<0.05) with the exception of Hb which showed no significant difference (P>0.05) across treatment groups. The over 50% reduction in the trypanosomal load in the 130 mg/kg group in comparison with the control group brings to bare the anti-trypanosomal potency of the toad venom. The anti-trypanosomal activity demonstrated by the toad venom has provided basis for development of new therapeutic agents from different toad species. The study recommends further studies (both in-vivo and invitro) followed by the characterization of the active compounds present in the toad venom responsible for the anti-tyrpanosomal activity observed alongside the management and conservation of these species
Trading Strategies for All Stock Programs
No full text Market traders buy and sell volatile assets frequently, with a goal to maximize their total return. There is usually a commission for each purchase and sale. Two such assets are gold and bitcoin. In order to solve the existing issues of purchases between gold and bitcoin, given that we have 1,000 USD, what strategies should we take to maximize our profits? In this article, the authors established seven models to predict the value of gold and bitcoins and how you should buy them, as the trends of value fluctuate, our models must be accurate enough to avoid being influenced. Targeted at that, the content is divided into three parts. For part 1: The authors selected several indicators that feature how the stock runs. For instance, price of gold and profit of gold to build first two models, which are the risk of investment model and the judgment on bull-or-bear market model. Then we use these models to evaluate whether it is safe to invest. The models are as follows: bear-bull market judgment model, risk of investment evaluation model, prediction model, trade model. For part 2: Based on the data concerned, the authors established the time series model to predict the way the market fluctuates. Meanwhile, the result of this model can be applied in correcting the results of former two models so as to make it more accurate. For part 3: The authors combined models above to give the best trading strategy. In addition, we improved the models by adding more indicators to make it more precise. We hope that by applying our models and strategies, you can successfully maximize your profit
Growth Assessment in Camel (Camelus dromedarius): A Meta-Analysis Study
No full textIn domestic animals, the body weight is the ultimate result of growth which forms the basis of meat production. Sex, nutrition, breed and health are the main factors which influence the growth rate in animals. Heredity which is the major factor affecting the prenatal growth either directly through the genotype of the fetus or indirectly through the genotype of the dam. The prenatal growth patterns and development of the camel fetus is just like the fetus of cattle, however, the meat output from the breeding shecamels is limited often due to longer gestation periods, longer milk feeding periods, lower calving rates under traditional management system. A lot of variation regarding camelid daily growth rate exists that varies widely between breeds, within breeds and regions. There is a significant effect of pre-weaning and post-weaning growth rates on the final body weights in camelids. Management system, the available milk quantity, husbandry practices and vegetative conditions are the main factors that affect the pre and post weaning growth rates of camel calves. However, it is partially dependent on the availability of browsing species throughout the whole year. In this specific study, an effort has been drawn to look into the literature data for camel growth assessment
