56. CONCEPT, TYPES AND TASKS OF THE INVESTIGATIVE EXPERIMENT

Investigative experiment - investigative action, consisting in the reproduction of actions, as well as the situation and other circumstances of a certain event.

Goal investigative experiment - verification and clarification of data relevant to a criminal case.

Tasks of the investigative experiment:

1) obtaining new and checking existing evidence;

2) assessment of investigative versions about the possibility or impossibility of the existence of certain facts relevant to the case;

3) obtaining truthful testimony from the suspect, the accused, the victim and the witness;

4) restoration in the memory of the participants in the crime of certain circumstances that they had forgotten or about which they were honestly mistaken;

5) establishing the causes and conditions conducive to the commission of a crime.

Methods used during the investigative experiment:

1) modeling;

2) experienced actions;

3) observation;

4) comparison.

Types of investigative experiment:

1) checking the possibility of perceiving any facts;

2 verification of certain actions;

3 checking the occurrence of an event;

4 identification of the sequence of the event and the mechanism for the formation of traces;

5) determination of the presence or absence of professional or criminal skills.

Actions of the investigator before the start of the investigative experiment:

1) making a decision to conduct an investigative experiment;

2) careful study of the case materials;

3) performance of other investigative actions;

4) drawing up a plan for an investigative experiment;

5) choice of place and time for conducting an investigative experiment;

6) preparation of objects necessary for conducting an investigative experiment;

7) preparation and verification of scientific and technical means for fixing the course and results of an investigative experiment;

8) familiarization with special literature;

9) conversations with specialists;

10) determination of the circle of participants in the investigative experiment.

Actions at the beginning of the investigative experiment:

1) establishment at the place of conducting the investigative experiment of changes that have occurred since the moment of the verified event;

2) reproduction of those conditions without which it is impossible to achieve a reliable result;

3) checking the availability of objects necessary for conducting an investigative experiment;

4) explanation of the goals and objectives of the upcoming experiment to its participants, their rights and obligations, and briefing.

General tactics:

1) the conditions for the production of an investigative experiment must be the same in which the event under test occurred, and if it is impossible or difficult to completely reproduce the conditions, then the conditions must be as close as possible to the original ones;

2) the use of authentic or maximally similar objects during the investigative experiment;

3) experiments must be repeated at least three times;

4) changing the conditions of experimental actions;

5) division of the production of an investigative experiment into stages;

6) simulation of the environment for the production of experiments.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Random news from the Archive Contraceptive gel for men 09.07.2012 The application of an experimental contraceptive gel containing a combination of two sex hormones (testosterone and progestin) to the skin reduces the sperm count in the ejaculate of 89% of men to very low values. In the male body, progestins (synthetic analogues of the female sex hormone progesterone) enhance the contraceptive effect of testosterone. In combination, these two hormones suppress the production of other hormones that regulate sperm formation. Earlier versions of male hormonal contraceptive methods based on this hormonal combination involved the use of progestin-containing pills, implants, or injections. The new contraceptive drug, developed by researchers at the Los Angeles Institute for Biomedical Research, is a gel applied to the skin that contains the male sex hormone testosterone and a newly developed progestin called nonsider. In addition to the ease of use of the gel, its serious advantage lies in the fact that Nestoron does not have androgenic (inherent in male sex hormones) activity, which can have side effects, such as the appearance of acne or changes in the levels of good and bad cholesterol in the blood. As part of a primary clinical study, researchers randomly divided 99 healthy men into 3 groups, each of which used one of 6 unidentified gels daily for 3 months. The tested preparations were a gel containing 10 mg of testosterone, or the same gel in combination with a gel containing 8 or 12 mg of nestosterone. 56 men adhered to the study protocol for at least 20 weeks. However, only 23% of participants who used testosterone gel, the concentration of sperm dropped to 1 million per milliliter - a level considered to reduce the likelihood of conception to almost zero. The use of the combined gel provided a similar result in 88-89% of men, depending on the dose of progestin. At the same time, the complete absence of spermatozoa was observed in 78% and 69% of participants who used gels containing 8 and 12 mg of progestin, respectively. For the control group, which used only testosterone gel, this figure was only 23%. The absence of undesirable side reactions when using the experimental gel indicates the advisability of its further testing in clinical trials.
