Comparison of convective and radiant heating system for office building with transparent facade system

Today’s architectural decisions for office buildings often include open plan of the space and transparent facade systems. It creates a lot of challenges for HVAC-engineers while designing the heating system. The most common approach nowadays is in-floor convectors near external walls around the perimeter. But it has certain disadvantages in terms of indoor climate conditions. Another possibility is to design a system with radiant ceiling panels which are widely applied nowadays in large halls, but not so widely in office buildings with normal heights. The aim of this bachelor’s thesis is to find out which one of two of heating systems for office building with transparent facade system is preferable from the point of their advantages and disadvantages, created indoor climate conditions and cost-efficiency. The methods used in the paper are the following. Firstly, literature research of the information about modern transparent facade system technologies, radiant and convective heating principles, their pros and cons. Then designing the simple building model and heat losses calculations for one typical floor, preliminary design of heating systems with in-floor convectors and radiant ceiling panels. Finally, cost calculations for each system, analysis of all information obtained and making a conclusion

From BPMN process models to DMN decision models

The interplay between process and decision models plays a crucial role in business process management, as decisions may be based on running processes and affect process outcomes. Often process models include decisions that are encoded through process control flow structures and data flow elements, thus reducing process model maintainability. The Decision Model and Notation (DMN) was proposed to achieve separation of concerns and to possibly complement the Business Process Model and Notation (BPMN) for designing decisions related to process models. Nevertheless, deriving decision models from process models remains challenging, especially when the same data underlie both process and decision models. In this paper, we explore how and to which extent the data modeled in BPMN processes and used for decision-making may be represented in the corresponding DMN decision models. To this end, we identify a set of patterns that capture possible representations of data in BPMN processes and that can be used to guide the derivation of decision models related to existing process models. Throughout the paper we refer to real-world healthcare processes to show the applicability of the proposed approach

Peculiarities of mercury content in the muscle tissue of fish of the Vologda Region

Mercury is one of the most dangerous toxicants for all living organisms, having a high degree of biomagnification. The determination of mercury concentration in different species of fish is important for evaluation of the state of aquatic ecosystems. The aim of research is study of peculiarities of mercury content in fish of the Sheksna Reservoir, the Sukhona River, Kubenskoye, Borovskoye and Svyatoye lakes. Mercury concentration in fish muscles of the Vologda Region varies from 0.0397 mg/kg to 1.167 mg/kg of wet mass. The highest average of mercury content is established in the muscle tissue of river bass (0.477±0.202), and the lowest average is in the muscle tissue of eastern bream (0.133±0.082). Mercury level does not exceed maximum permissible concentration of heavy metal and weekly norm, harmless for a person weighing 70 kg in most of examined specimens. Сomparison of mercury content in muscles of fish from surveyed water bodies showed a significant difference between river bass and most non-piscivorous species, as well as between individuals of river bass from Svyatoye and Borovskoye lakes. We also revealed a reliable correlation dependence of mercury content in the muscle tissue on mass and length of body for samples of river bass, northern pike and silver bream. Values of mercury concentration in the muscle tissue of river bass from Lake Kubenskoye and the Sheksna Reservoir vary in process of time

Innovative technologies of psychological support for children with disabilities

The relevance of this study is conditioned by the problem of developing and implementing innovative methods, technologies of working with disabled children. The purpose of this article research is to consider and to form a presentation of psychological aid innovative methods in order to support children with special needs by the methods of canis therapy and puppet theatre psycho-technology. The leading method of investigation this problem is the method of theoretical analysis, the method of ascertaining and educational experiment in the form of individual and group work. The proposed microtechniques of these innovative technologies make it possible to create a safe psychotherapeutic environment, reduce resistance, anxiety, and remove the used psychological protection of children and adolescents with special needs. The materials of the article can be useful for all subjects of the educational environment, who are taking part in inclusive education and upbringing: psychologists, teachers, speech therapists, speech pathologist, social workers, medical workers

Conservation of forest ecosystems in regional complex nature reserves

Based on the analysis of expedition, stock, published and official cadastral materials on the specially protected natural areas, the article characterizes complex (landscape) nature reserves of the Vologda region in the context of the landscape concept of formation of the network of specially protected natural areas in the region, and gives assessment of the compliance of the nature reserves with biodiversity conservation tasks under the taiga zone conditions. The history of establishment of nature reserves, the species and age composition of forests, the typological diversity of forests, availability of valuable natural areas, rare and protected species of plants and animals in 75 nature reserves were analyzed

Consistent Integration of Decision (DMN) and Process (BPMN) Models

Abstract. Organizations use business process and decision management techniques to run their businesses more efficiently. Modeling the business processes and decisions is a vital part of this. The recently proposed Decision Modeling and Notation (DMN) standard introduces a declarative approach for modeling decisions and aims at the separation of decision logic from business processes. Decoupling decisions and process models is crucial for the flexibility and maintainability of business processes. However, this aspect has received little attention, except in straightforward situations. In this paper we identify five integration scenarios and provide a formal basis for DMN models. Using these scenarios and formalization we illustrate how to achieve consistent integration of decision and process models

Effect of Short Photoperiod on Behavior and Brain Plasticity in Mice Differing in Predisposition to Catalepsy: The Role of BDNF and Serotonin System

Seasonal affective disorder is characterized by depression during fall/winter as a result of shorter daylight. Catalepsy is a syndrome of some grave mental diseases. Both the neurotransmitter serotonin (5-HT) and brain-derived neurotrophic factor (BDNF) are involved in the pathophysiological mechanisms underlying catalepsy and depressive disorders. The aim was to compare the response of behavior and brain plasticity to photoperiod alterations in catalepsy-resistant C57BL/6J and catalepsy-prone CBA/Lac male mice. Mice of both strains were exposed for six weeks to standard-day (14 h light/10 h darkness) or short-day (4 h light/20 h darkness) conditions. Short photoperiod increased depressive-like behavior in both strains. Only treated CBA/Lac mice demonstrated increased cataleptic immobility, decreased brain 5-HT level, and the expression of Tph2 gene encoding the key enzyme for 5-HT biosynthesis. Mice of both strains maintained under short-day conditions, compared to those under standard-day conditions, showed a region-specific decrease in the brain transcription of the Htr1a, Htr4, and Htr7 genes. After a short photoperiod exposure, the mRNA levels of the BDNF-related genes were reduced in CBA/Lac mice and were increased in the C57BL/6J mice. Thus, the predisposition to catalepsy considerably influences the photoperiodic changes in neuroplasticity, wherein both C57BL/6J and CBA/Lac mice can serve as a powerful tool for investigating the link between seasons and mood
