Problems in general physics

Ebook "Fundamentals of soil science (8th edition)" revision of a bestselling text shows that soil is three-dimensional and dynamic. This concept is developed in the first two chapters and is built on throughout the book. Chapters 3 through 7 explore soil physical properties and water, with expanded coverage of tillage and traffic and an increased emphasis on water and wind erosion processes. Chapters 8 through 11 discuss the biological aspects of soils as well as their mineralogical and chemical properties.

In this word, we wish to investigate the backward problem for the time-fractional wave equation in a general bounded domain. It plays its great important role in engineering areas and aims at detecting the inifial information of a physical field from its final data. We prove that the above backward problem is ill-posed in the sense of Hadamard.

The increase of population forced construction, transportation, industrial production, agriculture, and mineral resource exploitation to increase to serve human needs. These are also the main emission sources causing environmental pollution in general and air pollution in particular. The authors collected data analyzing the changes in air pollutants in the 2007-2016 period, from which to analyze the sources of pollution and the results of the paper contribute to improving people's awareness of environmental protection and also offer some solutions to reduce environmental pollution in Vietnam.

In recent years, a raising problem encountered by high school students in general and rural ones in particular is extremely bad speaking skill. This leads to a serious subsequence is that quality of students is low as well as learning and teaching have to face to many difficulties due to the reason that speaking skill is an essential instrument when learning communication in any another language. The problems were related to speaking materials, students’ physical limits, and supporting equipment.

Musculoskeletal pain is common in the general population and constitutes a major public health problem. A large proportion of these conditions may be work related. The aim of this study was to explore the relative importance of physical, psychosocial and personal factors, in number of pain sites and in five specific pain sites, among women in common professions with a broad variety of occupational exposures.

In this paper, we investigate the existence and uniqueness of fuzzy solution for a class of general hyperbolic equations with state-dependent delays. We will prove the well-posedness of problem doesn’t depend on the domain and boundary data as well as initial data. Our method is based on Banach fixed point theorem in completely new weighted metric space.

Domestic violence has been a serious problem in Vietnamese society, causing serious consequences for society, seriously violating human rights. Children, who are restricted in self-defense, physically and mentally vulnerable are one of the most severely affected subjects. Therefore, the prevention and control of domestic violence are very important activities in protecting human rights in general and in protecting children in particular. In doing so, the first thing is to change children’s perceptions of domestic violence and to protect themselves against domestic violence.

In higher education, it is essential to change teaching method toward the learnercentered orientation. Teaching through topics with practical content is one of the preferred options today. Problems in real-life contain complex elements that are almost impossible to explain by just one subject. The paper presents the method of organizing thematic teaching to foster pedagogical students’ ability to integrate interdisciplinary knowledge so that they can explain practical problems based on evidence and scientific foundations in the General Physics teaching process.
