In order to exploit DNA evidence, biological liquid must be detected and recovered. It has been suggested that some hostile conditions like a long water soaking period may have an influence on evidence recovery and thus results and interpretation. These researches demonstrate that adapting a protocol for each situation allows to recover any evidence.
Introduction: Age estimation is essential in human identification, but also in civil and pension lawsuits. Teeth maturation is better than other structures and the dental changes provide characteristics which are grouped in different age estimation methods.
Objective: The purpose of this literature review was to present the main methods in age estimation that have been currently used.
Forensic Palynology contributes to the evidence of the crime site and sometimes the moment of the fact by the study of pollen and spores and other palynomorphs present in the scene. Pollen morphology is sometimes exclusive for a plant species and some of them grow in specific areas besides plants produce pollen at certain times of the year. Some of the methods used to obtain the samples are here described, and they depend on the material to be analyzed. An alternative treatment for the tape method is proposed.
The developing countries bear a large share of burden and account for about 85% of the deaths as a result of road traffic crashes. So, the problem of road traffic accidents is becoming recognized concern. Motor-vehicle accidents are complex events resulting primarily from human, technical, and environmental contributing factors. Identification of the most probable factors that affect accident severity is the basis for effective road traffic accident prevention.
In science, the publication and presentation on the findings or ideas is the main step for generalization of new knowledge and support the development of the scientific community. An important problem that has been detected for a long time is an unethical practice, namely "plagiarism".
In this paper we would put a mathematic relation between the displacement(x2) of penetration of the lunched bullet inside the victim and the displacement(x1) in air before impact. The cardinal achievement of the article is that we use the physical definition of the inertial own mass of the matter as defined in the paper published by the author in 2014 under the title; physics of the giant atom [5].
