  • Ancient extinct life forms fossilized through volcanism in sedimented rivers and other plains of Mars

    The use of rules laid in earlier articles of the author allows to isolate the remains of life forms on Mars. All of these life forms have perished in volcanic eruptions. Pyroclastic flows, mudslides and the lava fill-up of underwater caves are shown to have killed by surprise the animals. The violence of the event allows conservation of the remains, as the covering by tuf, lava, hot mud, allows the casting of rock molds. An early observation of a femur in 2014 was discarded as result of erosion. This finding comes together with a skull cast in stone. It is indeed a skull and a femur – this can be validated ex-post by crossing with the findings of the author in an earlier article and these new ones.

  • The Oklo spontaneous nuclear reactor case: a fireball startup creating the South Atlantic

    There is a need to clarify continental formation processes and the Oklo natural nuclear reactor happens to be in the exact position where such a natural phenomena needs to be to explain continental separation. New research points of the author are shown to fit with findings of the French Commissariat à l’énergie atomique here.

  • A SonarQube Static Analysis of the Spectral Workbench

    The Spectral Workbench is an open-source, community driven software suite to obtain and disseminate spectral data. It consists of a client application that collects spectral readings and a server application that is an online database of spectral data. It is difficult to detect software defects in the Spectral Workbench application. A static analysis tool, SonarQube, was selected to find these defects. Numerous defects were detected and documented. SonarQube will increase the reliability of the Spectral Workbench, which provides numerous benefits including increased confidence in its data and effectiveness which will drive additional number of users for spectral repository data collection.

  • Disaster management strategy for avoiding the future losses by a slope failure at Nanhuan road, Fuxin area, Northeast China

    Many surrounding areas in the vicinity of failed slope at Nanhuan road, Fuxin area, Northeast China are witnessed as the signs of disaster. The observed settlement as wastage of an active mass in the area has been observed after the excessive precipitation in 2012 (May to October) which caused infrastructural damages (Roads at the top and bottom of the failure zone), agricultural fields and residential areas. Therefore, the paper proposes examining this subject. An extensive field investigation was conducted in the area of Fuxin, west of Liaoning province China. It is recommended and suggested that a series of disaster prevention and both structural and non-structural mitigation measures with the involvement of government and local community are required, to be prepared in advance for avoiding the future economic loss as well as the impending disaster in the area. This paper also highlights the need of investigation in response mechanism and forward planning for awareness initiatives: to avoid the future hazard in the remotest failure zones of Fuxin area, Northeast China.

  • Using Mathematical Model to Analyze the Northward Migration of Marine Life

    This paper studies the migration of fish caused by the rise of sea water temperature caused by global warming. It is required to predict the migration sites of herring and mackerel in the next 50 years, as well as the best, worst and most likely time for small-scale fishing companies in the original area of Scotland to continue fishing, and to formulate reasonable business strategies for such companies, while taking into account the territorial waters of other countries. The grey prediction model and linear regression model are established. By querying the sea temperature in the geographic location range ( , ) from 2010 to 2018, we predict it in terms of the quarter as the time unit. Because the result of grey prediction model is not in accordance with the reality, the final data is obtained by linear regression model. According to the data analysis, the migration routes of fish are all northward, and the main direction is to migrate to the coast of Norway, but some of herring will move to the coast of Iceland later. The grey prediction algorithm and BP neural network algorithm used in this paper have been widely used in solving all kinds of practical problems in reality, so the conclusion of this paper is feasible and extensive.

  • Motor Vehicle Maintenance Scheduling Model Based on Genetic algorithm

    To solve the problem of EMU maintenance planning time, we established a hybrid linear programming model based on adaptive genetic algorithm. According to the different levels of bullet train maintenance and the different arrival time, the constraint conditions are found, and the overall minimum maintenance time is taken as the objective function. Then the problem is transformed into a hybrid Flow-shop scheduling problem with unique process constraints, and an adaptive genetic algorithm is used to solve it again. It is concluded that the total maintenance takes 1125 minutes, and no blockage occurred in all EMU during the maintenance period. To provide a consistent basis for bullet train maintenance time and scheduling.

  • Integrated Application of Organic and Inorganic Fertilizer to Improve Nutritive Quality of Maize and Soybean Intercrop

    A field experiment was conducted to evaluate the use of integrated fertilizers on the nutritive quality of maize and soybean in intercropping system in 2014 at field 2, Universiti Putra Malaysia (UPM) Serdang, Selangor, Malaysia. Fertilizer applications were either in the form of inorganic (NPK) or poultry manure (PM). Treatments comprised of combinations of three intercropping systems (sole maize, sole soybean, and maize + soybean) and four nutrient managements (control, 100% NPK, 100% PM and 50 % NPK + 50% PM). The experiment was laid out in a randomized complete block design (RCBD) with 3 replications. Results showed that intercropping maize with soybean significantly reduced protein and nutrient content of soybean; however, the oil content of soybean, sugar, oil, protein and nutrient content of maize were not significantly affected by intercropping. Sole and integrated application of NPK and PM increased the quality of both crops over control. Integrated application of 50% NPK and 50% PM fertilizer gave higher oil, protein and nutrient content of both crops. Use of 100 % PM gave better quality than the application of NPK fertilizer for both crops.

  • Study on the pollution mechanism of drinking water source water to ultrafiltration membrane

    The effects of particulate matter (represented by humic acid, kaolin and algae) on ultrafiltration membranes in micro-polluted water sources were investigated, and the mechanism of ultrafiltration membranes was further understood with the change of membrane flux and transmembrane pressure difference. The results showed that the removal rate of kaolin and algae by UF membrane was over 99%, while the removal rate of humic acid was only about 72%. Moreover, the extent of UF membrane fouling caused by humic acid was larger than that caused by kaolin and algae. The higher the concentration of humic acid, the more serious the membrane fouling was. Ultrafiltration membranes contaminated by humic acid were washed by 0.05mol/L NaOH alkali and 0.05mol/L HCL acid. The permeability of the membranes was restored to 91.24% of the cleaned surface, which was better than that of pure water, sodium hypochlorite and sodium hydroxide. It can provide better guidance for choosing appropriate cleaning agents for ultrafiltration membrane fouling.
