Принципиальное значение запрета на поворот к худшему для уголовно-процессуальной системы

The article deals with the problem of the expediency of a criminal case’s returning to the prosecutor at the stage of appointment and preparation of a court session in Russian criminal proceedings. This problem is relevant to the science of criminal procedure.The purpose of the study is to analyze critically the practice of returning of a criminal case back to the prosecutor in order to correct mistakes made at the pre-trial stages of the proceedings according to the new concept of justice independence and the absence of an accusatory bias in the court functioning.The methodological basis of the study is a set of scientific techniques, focused mostly on the dialectical approach, which made it possible to determine the essential characteristics of the prohibition to turn the criminal proceedings in Russia for the worse. Both general scientific (analysis, synthesis, systematic method) and specific scientific methods (formal-legal, historical-legal, comparative-legal) of knowledge were also used. The analysis helped to formulate the position of understanding the turn for the worse as an independent principle of criminal procedural law, to study the procedural form of the turn for the worse. The synthesis method made it possible to determine the return of the criminal case to the prosecutor at the stage of appointment and preparation of the court session as a holistic institution of the criminal procedure. The systematic approach allowed to determine not only the mixed nature of the mechanism for changing the prosecution to a more serious one, but the investigative organization of pre-trial proceedings and its place in the structure of criminal proceedings, the separation of the investigative and “accusatory powers” of the prosecutors as well as their balance. The historical method let us trace the evolution of the prohibition to turn the Soviet and Russian criminal procedural systems for the worse. The comparative-legal method made it possible to assess the potential of domestic legislators' reception of foreign experience of regulating the prohibition to turn for the worse and formulate proposals to improve the Russian criminal procedural legislation.The main scientific results of this research consist of justification of the conclusion of the conversion expediency of the domestic judicial proceedings to the adversarial model of accusation which is carried out within the trial on the previously filed charge. The presentation of a new charge (criminal action) in court and the procedure of supplementing the charge change it for the worse. This model of re-indictment for the worse for the defendant appears to be fairer and more convenient both for the prosecuting authority and for the legal organization of combating crime. The changeover to the suggested form of implementation of the ban to turn for the worse in the institution of bringing and changing charges in court is possible only in a systematic link with the reform of the preliminary investigation. Conclusion. The institution of the criminal case returning by the court to the prosecutor in order to change the charge to a more serious one when implementing the adversarial model of bringing charges in the criminal procedure system of Russia will fully satisfy the concept of independence of justice administration and the absence of an accusatory bias in the activities of the court, while at the same time with fairly organized the prosecutorial power aimed at countering crime.The section 1 was prepared by N.N.

По мнению авторов, запрет на поворот к худшему имеет более фундаментальное значение для уголовно-процессуальной системы, чем ему обычно приписывает теория. Справедливость и эффективность процедуры возвращения судом дела на доследование, позволяющей следователю изменить положение подсудимого посредством предъявления нового обвинения, сомнительны. Предпочтительнее выглядит модель изменения государственным обвинителем обвинения в суде с соблюдением состязательной процедуры, существующая в ряде государств, имеющих состязательный тип уголовного судопроизводства.Раздел 1 подготовлен Н.Н.

Seasonal variation of carbon fluxes in a sparse savanna in semi arid Sudan

<p>Abstract</p> <p>Background</p> <p>Large spatial, seasonal and annual variability of major drivers of the carbon cycle (precipitation, temperature, fire regime and nutrient availability) are common in the Sahel region. This causes large variability in net ecosystem exchange and in vegetation productivity, the subsistence basis for a major part of the rural population in Sahel. This study compares the 2005 dry and wet season fluxes of CO₂for a grass land/sparse savanna site in semi arid Sudan and relates these fluxes to water availability and incoming photosynthetic photon flux density (PPFD). Data from this site could complement the current sparse observation network in Africa, a continent where climatic change could significantly impact the future and which constitute a weak link in our understanding of the global carbon cycle.</p> <p>Results</p> <p>The dry season (represented by Julian day 35–46, February 2005) was characterized by low soil moisture availability, low evapotranspiration and a high vapor pressure deficit. The mean daily NEE (net ecosystem exchange, Eq. 1) was -14.7 mmol d^-1for the 12 day period (negative numbers denote sinks, i.e. flux from the atmosphere to the biosphere). The water use efficiency (WUE) was 1.6 mmol CO₂mol H₂O^-1and the light use efficiency (LUE) was 0.95 mmol CO₂mol PPFD^-1. Photosynthesis is a weak, but linear function of PPFD. The wet season (represented by Julian day 266–273, September 2005) was, compared to the dry season, characterized by slightly higher soil moisture availability, higher evapotranspiration and a slightly lower vapor pressure deficit. The mean daily NEE was -152 mmol d^-1for the 8 day period. The WUE was lower, 0.97 mmol CO₂mol H₂O^-1and the LUE was higher, 7.2 <it>μ</it>mol CO₂mmol PPFD^-1during the wet season compared to the dry season. During the wet season photosynthesis increases with PPFD to about 1600 <it>μ</it>mol m^-2s^-1and then levels off.</p> <p>Conclusion</p> <p>Based on data collected during two short periods, the studied ecosystem was a sink of carbon both during the dry and wet season 2005. The small sink during the dry season is surprising and similar dry season sinks have not to our knowledge been reported from other similar savanna ecosystems and could have potential management implications for agroforestry. A strong response of NEE versus small changes in plant available soil water content was found. Collection and analysis of flux data for several consecutive years including variations in precipitation, available soil moisture and labile soil carbon are needed for understanding the year to year variation of the carbon budget of this grass land/sparse savanna site in semi arid Sudan.</p

Climate controls over ecosystem metabolism: insights from a fifteen-year inductive artificial neural network synthesis for a subalpine forest

Eddy covariance (EC) datasets have provided insight into climate determinants of net ecosystem productivity (NEP) and evapotranspiration (ET) in natural ecosystems for decades, but most EC studies were published in serial fashion such that one study's result became the following study's hypothesis. This approach reflects the hypothetico-deductive process by focusing on previously derived hypotheses. A synthesis of this type of sequential inference reiterates subjective biases and may amplify past assumptions about the role, and relative importance, of controls over ecosystem metabolism. Long-term EC datasets facilitate an alternative approach to synthesis: the use of inductive data-based analyses to re-examine past deductive studies of the same ecosystem. Here we examined the seasonal climate determinants of NEP and ET by analyzing a 15-year EC time-series from a subalpine forest using an ensemble of Artificial Neural Networks (ANNs) at the half-day (daytime/nighttime) time-step. We extracted relative rankings of climate drivers and driver-response relationships directly from the dataset with minimal a priori assumptions. The ANN analysis revealed temperature variables as primary climate drivers of NEP and daytime ET, when all seasons are considered, consistent with the assembly of past studies. New relations uncovered by the ANN approach include the role of soil moisture in driving daytime NEP during the snowmelt period, the nonlinear response of NEP to temperature across seasons, and the low relevance of summer rainfall for NEP or ET at the same daytime/nighttime time step. These new results offer a more complete perspective of climate-ecosystem interactions at this site than traditional deductive analyses alone

Using high resolution cardiac CT data to model and visualize patient-specific interactions between trabeculae and blood flow

Abstract. In this paper, we present a method to simulate and visualize blood flow through the human heart, using the reconstructed 4D motion of the endocardial surface of the left ventricle as boundary conditions. The reconstruction captures the motion of the full 3D surfaces of the complex features, such as the papillary muscles and the ventricular trabeculae. We use visualizations of the flow field to view the interactions between the blood and the trabeculae in far more detail than has been achieved previously, which promises to give a better understanding of cardiac flow. Finally, we use our simulation results to compare the blood flow within one healthy heart and two diseased hearts.

Scaling up of Site Carbon Dynamics to Predict the Carbon Dynamics in Kazakhstan, Central Asia

Climate and management determine whether rangelands are net carbon sources or carbon sinks. Regional carbon dynamics of the Kazakh Steppe has not previously been documented. The objective of this study is to quantify the regional carbon flux dynamics of these extensive steppes
