Comprehensive Study

The fundamentals of an interdisciplinary approach to the design of greenhouse production systems are considered, in which biological objects (plants and humans) are present. The conceptual approach of the software solution is analyzed, synthesizing on the basis of the objectoriented concept such directions as disciplines on the construction of greenhouse production, dynamic simulation models, geoinformation systems. Based on the study of this issue, the conclusion was made about the advisability of applying an interdisciplinary approach for a comprehensive study of the projected complex biotechnical systems of greenhouse production.

The paper dedicates in commemoration of K.A. Bagrinovsky, known scientist, doctor of economic sciences, professor. His thesis was theoretic problems of mathematical modeling and operation of economy. His works in the operations research, the methods making decision, the simulation were received in scientific world. The analysis and the modeling of the mechanisms for scientific and technological development for the production systems of different level in economic hierarchic both centrally controlled economy and making mechanism were conduced by Bagrinovsky in CEMI RAS. The paper presents the investigations (2001–2015) of the analysis and the simulation of the different mechanisms of the innovational activity. It also discusses the methods of the development the complex of the simulation models. In a sense simulation modeling is the science and the art as the selection of the salient parameters for the construction model, intake simplification, the computer experiment and the making decision based on scarcity of accuracy models rest on the heuristic power of men: the practical trial, the intelligence and the intuition. K.A. Bagrinovsky introduced the considerable endowment in the development of this direction for economic and mathematical investigation.The principal object was to show that the relationship between the innovational policy and the technological structure, scientific research sector and the introducing of the progressive production and the organizational structure is obtainable by the models. The character of these relationships may be to use in control of the parameters for the modernization economic. The construction simulation models and the experimental computation analysis were presented the investigations the different mechanisms of the innovational development ant the variants of the estimation have been accomplished on the modeling level by the computer experiment.

Dear Readers, Welcome to the sixth edition of the JEVTM! In 1866, the Great Russian surgeon and scientist Nikolai Pirogov wrote: “A new era for surgery will begin, if we can quickly and surely control the flow in a major artery without exploration and ligation”. This era has now arrived and it is called EVTM! Our mission has been to maximize the benefits of endovascular technologies for trauma and bleeding patients: from the first attempts of REBOA by Carl Hughes in the 1950s with hand-made aortic balloon occlusion catheters used in our department since the early 1990s to modern successful cases of out-of-hospital REBOA use in combat and civilian casualties for ruptured aneurysms, post-partum hemorrhage and trauma. In this edition, you will find articles related to a new strategy of damage control interventional radiology (DCIR), partial REBOA in elderly patients and in ruptured aortic aneurysms, thrombolysis for trauma-associated IVC thrombosis, simulation models for training of REBOA, contemporary utilization of Zone III REBOA and more. As a continuation of EVTM development, Russian surgeons, emergency physicians, anesthetists, and others will be involved in the world of EVTM, participating in expanding the horizons of trauma care and cultivating the endovascular mindset. Also published in this edition are some of the abstracts that will be presented at the EVTM conference in Russia, St. Petersburg (7/06/2019). More than 35 oral and 30 poster presentations will make this conference a scientific feast for our audience! By adopting these new techniques for bleeding management, we are following Pirogov’s motto – to achieve fast endovascular hemorrhage control – which can only be done as part of an interdisciplinary approach.   We look forward to seeing you in Saint Petersburg at the EVTM-Russia meeting! www.evtm.org

Mode Of Production

An emerging feature of contemporary development studies in India is the deployment of an interdisciplinary approach involving geographical location, level of poverty, nature of development and planning etc. The prevalence of poverty in a specific geographical location represents the evolving pattern of deprivation under a particular mode of production. The historicity of poverty in a geographical space needs an independent enquiry and identification of different production systems which are responsible for the problem of deprivation through multiple routes. The present paper is an attempt to initiate a debate on the issue of poverty, especially in a tribal region, through a multi-dimensional perspective, i.e. interrelation between geography, poverty, development and planning. The paper identifies one of the most poverty-stricken regions of India for a detailed discussion of the various casual factors which are apparently responsible for the poverty of that region. The paper also tries to explore the historical background of poverty in the study area (Babhani Block of Sonbhadra U. P.).

What's in a Model? Issues in the Use of Simulation Models to Analyze Student Understanding: A Reaction to Ohlsson, Ernst, and Rees

Student Understanding

Ohlsson. Ernst, and Rees (this issue) have produced a wonderfully lucid description of their paradigmatic approach to issues of cognition and instruction. They illustrate their approach by presenting the details of a well worked out computational model. Then, on the basis of simulation runs on the model, they derive some implications for prac tice. The authors have also laid down some rather stringent constraints for commentary. Do not critique our paradigms, they say, unless you can offer a replacement that does better. Do not critique the choice of knowledge representation (production systems) or modeling assumptions (e.g., limitations on working memory) unless you have compelling data to offer in service of your argument and in contradiction of our assumptions. Argument about details is useful, they say, but that won't change the conclusions we draw. So what's a reviewer to do?

Temperature management has emerged as an important tool for plant height control in greenhouse production systems. This is particularly important in vegetable transplant production where chemical controls for plant height are limited or not legal. Plant height is a function of the number of nodes and the length of each internode, and both are strongly influenced by greenhouse temperatures. Node number, or formation rate, is primarily a function of the average greenhouse temperature, increasing as the average temperature increases. Internode length is strongly influenced by the relationship between the day and night temperature, commonly referred to as DIF (day temperature - night temperature). As DIF increases, so does internode length in most plant species studied. Although the nature and magnitude of temperature effects vary with species, cultivar, and environmental conditions, these two basic responses can be used to modify transplant growth. Although data are limited, controlling transplant height with temperature does not appear to adversely influence plant establishment or subsequent yield.
