Students as an intellectual group should be able to be pattern for the younger generation, for example to behave honestly and responsibly. In the making of writing products, students must have an honest attitude in making writing products. To create student's honest behavior cannot be separated from the role of the institution to form a culture of honest behavior by not doing plagiarism against the work of others. This is the reason of the author to make a study with the title Students Awareness on the Regulation of Intelectual Patent Rights on Their Writting Products (A Case Study on the Students of State Polytechnic of Madiun)Based on the principal issues stated above, the purpose of this legal research are:To know whether or not the students of State Polytechnic of Madiun have an awareness on the regulation of Intelectual Patent Rights On Scientific WritingTo determine what factors influence the level of regulation awareness of students State Polytechnic of Madiun to Copyright on Scientific WritingResearch method used in this research is empirical sociological approach method that have intention to observe how is the reaction and interaction happened when system norm (law) work in the society that is to know whether the students of State Polytechnic of Madiun already have an awareness of law to the Intellectual Patent Right of Scientific Writing and to know what factors may give influence to their level of law awareness of copyright on Scientific WritingBased on the above discussion about students 'legal awareness of intellectual property rights of copyrights on paper case study of Polytechnic State student of Madiun, it can be concluded that the students' legal awareness of copyright rights of writing is still low, indicated by the number of students who know about knowledge IPR / Copyright is still small. The copyright infringement is still committed, i.e., taking photocopies of ordinary and reasonable regardless of the sanctions or rules, then in the case of quoting other people's scientific papers or books, the awareness to include the source of the quotation is still low.Regarding the factors behind the level of law awareness of the students of State Polytechnic of Madiun on the copyright of the paper, the first factor of knowledge and understanding of law, as a whole the students have a low level of knowledge and legal understanding, can be seen from the two aspects contained in it that is about knowledge rules or laws governing and their aims and objectives. Many respondents who only know one of them, know the rules governing, but do not know the purpose of the rule, vice versa. The second concerning legal attitude and legal behavior, most of the students' legal attitude is good, but still many are not good, due to cultural habit factor in the environment and influenced by friends around.
The Effect of Dormancy Breakdown through Water Immersion with Temperature Stratification on the Germination of Sugar Palm Seeds (Arenga pinnata)

Published: January 2020

Sugar palm (Arenga pinnata) has a hard and impermeable pericarp, which make an obstacle for it’s germination. Scarification of seed is needed to breakdown the physical dormancy of seeds. One of the methods to break the physical dormancy is stratification by soaking seed in to the water in some different temperature level. The aims of the study were to determine the effectiveness of stratification and to figure out the best water temperature in breaking the dormancy. A Completely Randomized Design (CRD) in four treatments (control, water immersion at 25°C, 50°C, and 75°C) with four replications was employed as research design. Statistical analysis was conducted using homogenity of variance, variance analysis, and least significant difference tests. The result showed that the water immersion of arenga seed at 25°C and 50°C resulted in the germination percentage, germination rate and test germination that was comparable to control. Water immersion at 75°C reduced the percentage of germination and germination rate, however the treatment could increase the germination test. Water immersion of arenga seed at 25°C, 50°C, and 75°C were not effective to break the dormancy of sugar palm seed.Keywords: aren seeds, dormancy, water immersion

Several West African countries have recently reported of Yellow Fever outbreaks. Ghana recently recorded an outbreak which lead to the death of three (3) people in the West Gonja District of the Northern Region. These indicate the re-emergence of the deadly disease. This research proposes a deterministic mathematical model through non-linear ordinary differential equations in order to gain an accurate insight into the dynamics of yellow fever between human beings and the vector Aedes mosquito in an unvaccinated area for the purpose of controlling the disease. The disease threshold parameter was obtained using the next generation matrix. The Gerschgorin theorem proved the disease-Free equilibrium and the Endemic equilibrium to be locally asymptotically stable for and respectively. The Lyapunov function proved the disease-Free Equilibrium to be globally asymptotically stable for . In order to study the effect of the model parameters to , the sensitivity analysis of the basic reproduction number with respect to epidemiological parameters was performed.
Non-Destructive Characterization of Subsurface Plastic Deformation in Case Carburized Steel Using Magnetic Barkhausen Noise Technique
Authors: Blaow Mohamed M. , Ballem Mohamed Ali , Shaw Brian Andrew 
Published: January 2020

The effect of extreme loading in bending was investigated by magnetic Barkhausen Noise (MBN) and X-ray diffraction (XRD) in two types of inhomogeneous steels that widely used in gear industry. EN 36 and H8620 steels in the carburized, tempered and ground condition were investigated after unloading from high stress levels. The inhomogeneity arising from the variation in carbon content showed up clearly by double peaks MBN profiles before loading. The first MBN peak at low field revealed the soft subsurface region and the second peak at higher field revealed the hard surface layer. Residual stresses profiles were produced by XRD before and after loading to probe plasticity in the cross sections of both specimens. Barkhausen noise measurements showed a considerable change in the first peak height in both steels as a response to plastic deformation in tension and compression in the subsurface material. The height of the second peak remained unchanged in EN 36 specimen but increased slightly in the H8620 specimen. The residual stress measurements after unloading indicated that the subsurface materials after a depth of 0.4 mm in both specimens were yielded. The surface layer of the H8620 steel was also affected slightly by bending as revealed by an increase in the second MBN peak height and confirmed by XRD as indication of yielding. The experiment confirmed that the magnetic Barkhausen noise can be used to characterize yielding in inhomogeneous steels non-destructively.
Single Harmonic Black Holes
Authors: Vegt Wim 
Published: January 2020

In this New Theory a “Single Harmonic Black Hole” (SHBH) has been considered to be the Gravitational-Electromagnetic Confinement of a Single Harmonic Electromagnetic Field Configuration in which a perfect equilibrium exists between the outward directed electromagnetic radiation pressure and the inward directed Electromagnetic-Gravitational Interaction force densities. This frequency transformation is possible because of the combined Lorentz / Doppler-Effect transformation during the collapse (contraction) of the radiation when the Gravitational Electromagnetic Confinement has been formed (Implosion of Visible Light). Within the scope of this article “Single Harmonic Black Hole” (SHBH) is considered to be any kind of 3-dimensional confined Single Harmonic Electromagnetic Energy. The inner structure of a “SHBH” has been based on a 3-dimensional isotropic equilibrium within the electromagnetic field configuration. This new theory will explain how electromagnetic fields (wave packages) demonstrate inertia, mass and momentum and which forces keep the wave packages together in a way that they can be measured like particles with their own specific mass and momentum. To understand what electromagnetic inertia and the corresponding electromagnetic mass, spin and electric charge is and how the anisotropy of electromagnetic mass, spin and electric charge can be explained and how it has to be defined, a New Theory about “Electromagnetic-Gravitational Interaction” has been developed. The “New Theory” has been based on the fundamental principle of “Perfect Equilibrium within the Universe” which has already been expressed by Newton’s three equations published in 1687 in “Philosophiae Naturalis Principia Mathematica. Newton’s Equations in 3 dimensions will be published in this article in an extension into 4 dimensions. Newton’s 4-dimensional law in the 3 spatial dimensions results in an improved version of the classical Maxwell Equations and Newton’s law in the 4th dimension (time) results in the quantum mechanical Schrödinger wave equation (at non-relativistic velocities) and the relativistic Dirac equation.

Published: January 2020

Summary
There is a growing need to analyze data sets characterized by several sets of variables observed on the same set of individuals. Such complex data structures are known as multiblock (or multiple-set) data sets. Multi-block data sets are encountered in diverse fields including bioinformatics, chemometrics, food analysis, etc. Generalized Canonical Correlation Analysis (GCCA) is a very powerful method to study this kind of relationships between blocks. It can also be viewed as a method for the integration of information from K > 2 distinct sources (Takane and Oshima-Takane 2002). In this paper, GCCA is considered in the context of multivariate functional data. Such data are treated as realizations of multivariate random processes. GCCA is a technique that allows the joint analysis of several sets of data through dimensionality reduction. The central problem of GCCA is to construct a series of components aiming to maximize the association among the multiple variable sets. This method will be presented for multivariate functional data. Finally, a practical example will be discussed.
