Background. Platelet-enriched plasma (PRP) is a revolutionary autologous biomaterial that stimulates bone regeneration, enhances regenerative processes and postoperative wound healing, thus simplifying future implant-prosthetic rehabilitation. Objective of the study. Evaluation of PRP regeneration properties in postextractional wound regeneration. Material and Methods. The clinical examination was used as research methods: inspection, palpation, paraclinical examination: panoramic radiography / CBCT and VAS test were performed. The diagnosis and treatment plan were established, as follows: extraction associated with PRP injection. Results. At the postoperative evaluation of the patient after 7 days of treatment, the intensity of pain according to the modified VAS method showed decreased values- from 4 to 1, the postextractional wound was completely healed, the level of regeneration was attested by the absence of dehiscence, presence of the pale pink epithelium, absence of the postoperative facial edema according to the craniometric points, the Celsius signs also were absent. Conclusion. The use of PRP biomaterial in wisdom tooth extraction is a minimally invasive method of tissue regeneration that reduces the rehabilitation period and prevents the occurrence of post-extraction complications.

Background. Coronectomy of the wisdom teeth is an alternative surgical procedure to tooth extraction, which aims to preserve the roots of the wisdom teeth in the dental socket after surgical separation of the crown, in order to avoid the injury of the inferior alveolar vascular-nervous bundle. Purpose. Minimizing the damage to the inferior alveolar nerve when extracting lower third molars caused by the intimate relationship between the nerve and the roots of the teeth, by using the technique of coronectomy, or intentional root retention. Material and Methods. Patients who reported to University Dental clinic during the period 2020–2021 for surgical removal of impacted L3M were screened for nerve–root relationship with OPG or CBCT. 15 patients underwent coronectomy as a procedure to remove the crown and upper third of the roots of a lower third molar to reduce the risk of damage to the inferior alveolar nerve. Results. 15 patients were enrolled in this study, with a total of 17 lower third molars. Sixteen sites healed primarily, but in 1 case the sockets on both sides opened and failed to close secondarily. In this case, the root fragments were later removed and found to be mobile. Conclusion. Coronectomies are safer to perform than complete extractions in situations in which the third molar is in close proximity to the mandibular canal. The technique appears to be associated with a low incidence of complications and the removal of remaining roots is required in around 6-7% of cases due to the mesial migration of the fragment and not any symptoms or reinfection.

Introduction. Guided bone regeneration is a real challenge of dentoalveolar surgery. Due to modern biotechnology, the use of polymers in guided tissue regeneration is becoming a promising method in dentoalveolar surgery. Objective of the study. Assessment of the role of use of polymeric mesh in guided bone regeneration in patients with marked alveolar atrophy. Materials and methods. Beginning of the study - 2018, the study included 25 patients with marked alveolar atrophy, aged 20-60 years who were divided into two groups, group I - 15 patients underwent guided bone regeneration using polymers, in the group II - 10 patients used perforated titanium mesh. The diagnosis and treatment plan were similar for both groups. Results. In study group I, there were complications in 5 patients, of which 3 patients developed small fenestrations and seromas, and two patients developed dehiscence of 2/3 of the gum suture line. In the second group of patients, in which titanium mesh was used, complications developed in 7 patients - 4 patients developed fistulas and fenestrations and 3 suffered massive dehiscences along the entire suture line. Conclusions: The use of polymer mesh in guided bone regeneration is a cost-effective method in dentoalveolar surgery, cheap and simple to apply. This method recorded fewer postoperative complications, fewer surgical stages, faster postoperative recovery.

The prosthetic result as well as the long– term success in implant–prosthetic rehabilitation depends on a series of factors such as: position, number of implants, surgical technique, bone and mucosal offer, and others. Usually, free hand surgery does not allow in all the cases to place implants in best position from the prosthetic and biomechanical point of view. Due to the development of scanning technologies and three–dimensional printing, the planning of final results allows the printing of surgical guides, to ensure the most accurate position of dental implants [1,2]. The comparative analysis of conventional and guided implant placement methods has demonstrated significant advantages in favor of guided surgery. However, with the application of additional maneuvers in the treatment (impression, scanning, planning, template fabrication), a number of disadvantages and errors were observed that may affect both, the treatment and results.

Peri-implantitis is a complication in implantprosthetic rehabilitation that causes morpho-functional, masticatory and aesthetic disorders. Depending on the severity it can be approached by conservative surgical or radical treatment. The aim of the paper is the comparative analysis of conservative surgical methods (implant preservation) versus radical (explantation). We studied 2 patients who came to the SRL “Omni Dent” clinic with peri-implantitis. Manifestation, treatment and evolution in both patients were compared. Analysis criteria: bone defect extension, soft tissue appearance, tissue regeneration, implant-prosthetic rehabilitation time. In RI patient there were changes in color and appearance of the peri-implant soft tissues (hyperemia, edema, purulent discharge), peri-implant radiolucency on the entire implant surface; in the TM patient there were the same clinical signs but limited to ½ implant length. RI patient underwent explantation with re-implantation in the neighboring region 2.4 after 4 months with prosthesis fixing after another 4 months. Tissue regeneration evolved without complications. In TM patient was decided to keep the implant through curettage, implantoplasty and bone addition. Prosthetic rehabilitation followed later without complications. Timely addressing would prevent the development of complications with implant loss. The insignificant loss of peri-implant tissues can be recovered with the preservation of the implant, in the extended defects the optimal solution is the explantation with the subsequent implantprosthetic rehabilitation.
Peri-implant soft tissue au gmentation with connective tissue graft using „Two stage“ technique

Soft tissue augmentation using autogenous gingival grafts is a procedure often used in implantology and periodontal surgery. The technique of connective tissue grafting refers to the placement of connective tissue under a flap of partial thickness, which aims to induce the formation of keratinized tissue. It is indicated for partially or totally edentulous patients to increase the areas with the absence or reduction of the height of the keratinized tissue, as well as to increase the volume of soft tissue. The structural differences between the implant / bone tissue interface and the natural tooth / bone tissue make dental implants more susceptible to the development of inflammatory processes and bone loss. For these reasons, the intangibility of the seal around the implants is one of the primary objectives in its success over a long period of time. The function of the peri–implant seal is to “maintain internal homeostasis in response to external environmental challenges.”

Published: October 2021

In historical aspect, the skill is among the key categories in the realm of human practice, which are often an object of different researches – psychological, pedagogical, and last but not least methodological. This is a fact, because the skill is a vital term for the description of productivity of learning experience at least in two dimensions – personally fundamental, guaranteeing its effective functioning in different situations and personally pragmatic, as a multi-level transformation of the cognitive experience, for the completion of certain social roles and the necessary qualities of the subject for this. The skill is a blend between those two dimensions of productivity both in higher education and in secondary school. The reflective skills are a structural and functional part of the transformation of the cognitive, affective, and psycho-motor experience and as such are included in the individual educational reality of the subject, and to a higher degree it defines it. This is the reason why the constructive-prognostic analysis of the reflective skill in the area of Methodology is pointing at the answer of the questions: What is this, what is its structure, how does it get integrated in the system of skills, how does it form and develop. The answers of those questions are basis of its methodological decoding in the process of training teachers and students in Biology. All of this describes the territory of the methodological context of analysing the reflective skill.
Methodological Framework to Develop Meaning Formation Categories in Methodology of Biology Education
Authors:   University of Sofia, Raycheva Nadezhda
Published: October 2021

Science could be thought as mature in cases it obtains clear terminology and methodology i.e. recognizable scientific language and object to be researched. The integrative sciences, such as the methodology of biology education, face the challenge to look for themselves “overshadow” of other sciences related to object or methodology. In search for defined territory among sciences, critically important is elucidating the categories and deducing fundamental concepts of a given science. Transfer of experience takes place in four-dimensional system – on first place, are ideas, on the second, are symbols, signs, and terms related with ideas; the third dimension is objective meaning, other words representation in reality (in culture as values – technological, ethical, aesthetical and so on) and the last dimension is methodological that marks interaction subject-object in research field. These four dimensions encompass the territory of scientific and educational sense and can be used as a methodological framework in developing fundamental categories of a specific science.

A part of a professional teacher’s competency is making the pedagogical design in the territory of the defined situation and includes numerous skills that function as a whole and are visible in final result related to evaluation and choice of educational resources or develop ideas for parts or for the whole process of education in a defined pedagogical context. Some of these skills that regulate professional decisions are related to retrospection of experience (learning, teaching, cognitive and affective), with an evaluation of elements of experience and after that with a choice what and how to take a part in the final professional decision. Adequacy with professional purpose and internal consistency and coherency in the decision are criteria for analysis of pedagogical construct. In the present report are discussed relations between fundamental pedagogical and methodological professional skills and their evaluating-reflective shell in context of design of professional pedagogical decision from perspective of ideal pre-defined situation.

В началото на 90-те години на миналия век, преди Международната конвенция за стандартите за освидетелстване и подготовка на моряците и носене на вахта от 1978 година да бъде напълно приложена в корабоплавателната индустрия, всеки корабособственик наема моряци според нуждите на конкретния кораб. Грижата за обучението и последващата квалификация е изцяло предадена на морските образователни институции. От началото на новото хилядолетие корабоплавателната индустрия е под въздействието на много регулаторни промени и бързото развитие в различни сектори. Едно от ключовите направления е подобряването на качеството на подготовката и квалификацията на моряците. Този процес не завършва с дипломирането в образователната институция, тъй като там се полагат основите на професионалната подготовка. Разширяването и поддържането на знанията и уменията, много от които са извън рамките на конвенционалните компетентности, се поддържат с допълнителни образователни форми и похвати. Като такава форма все повече се прилага организиране от почти всички корабоплавателни компании на семинари за корабните офицери. Тази статия представя обобщените резултати от такива семинари, проведени в различни градове и държави и от различни корабни компании. Прави се подробен анализ на силните и слабите страни на мероприятието „семинар за корабни офицери“ в контекста на принципите на науката „андрагогика“ и стратегията „Учене през целия живот“.

A novel series of metal complexes of coumarin Schiff bases have been synthesized by reacting to coumarin Schiff bases with cobalt (II) nitrate and zinc chloride. The IR, 1H and NMR spectral data were obtained to characterize the structures of newly synthesized compounds. Newly synthesized compounds were evaluated for acute anti-inflammatory activity using carrageenan-induced rat paw edema and analgesic activity by acetic acid induced writhing method. In acute anti-inflammatory activity, the rat paw volume was measured before and after 0.5, 1,3 and 6 h of the carrageenan injection. Compounds IIIajwere administered at a dose of 10mg/kg body weight, 0.5h before the carrageenan injection. The results showed 36.69, 45.87 and 31.19% inhibition of edematous volume at third hour against carrageenan induced paw edema.The compounds IIIa, IIIbandIIIcwere screened for analgesic activity and measured by noting the writhing response by acetic acid in mice gave 43.01, 34.05 and 26.24% of protection against acetic acid induced writhing, respectively. These results confirm the encouraging anti-inflammatory and analgesic activity of the metal complexes of coumarins Schiff bases.

Compared to other coasts, Libyan coasts are characterized by low levels of pollution. This makes them a suitable environment for marine diversity, especially seaweeds, which may be considered a source of new compounds that are biologically active in their resistance to microbes. Therefore, the present study was conducted with the aim of testing the bioactivity of leave and rhizome extracts of Posidonia oceanica seaweed (aqueous, ethanol, and acetone) at concentrations (50, 100, and 150) mg/ml against three types of pathogenic bacteria (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa), and fungus (Candida spp.), by a sensitivity test in the form of a disk diffusion method. The results showed that Posidonia oceanica seaweed extracts have good inhibitory activity against S.aureus and Candida spp., and that the concentration of 150 mg/ml is the most effective for all extracts. The results also indicated that rhizome extracts are more efficient than leaf extracts, and the acetone extract is the best in inhibiting the tested microbes. Also, Escherichia coli and Pseudomonas aeruginosa are the most resistant to all extracts, regardless of type and concentration used.

This study was conducted during the season 2019-2020 with the aim of testing the efficiency of some techniques to eliminate or reduce the frequency of storage fungi, namely Aspergillus flavus, A. niger, and Penicillium italicum naturally contaminating peanuts seeds. The seed sample was treated by soaking in hot water (50˚c, 60˚c, 70˚c), soaking in salt water at concentrations 10%, 15%, 20%, roasting in an ordinary oven at 150˚c for 10, 20 and 30 min, and roasting in a microwave oven at 100˚c for 1, 3, 5 and 7 min. The frequency of fungi occurrence percentage was estimated in seeds after treatments and incubation on the nutrient medium Potato Sucrose Agar (PSA). The results indicated the efficiency of all the techniques used in reducing the frequency of fungi in the treated seeds, as the fungus P. italicum was the most sensitive fungus under all techniques, and the study proved the superiority of the treatment by microwave roasting over the rest of the techniques, as it eliminated all the fungi carried in the seed by 100% when the duration of time used is 5 minutes.
PRICING MODEL FOR FPSO CHARTERING

Published: October 2021

Floating Production, Storage, and Offloading (FPSOs) are vessels utilized to produce, process, and storage oil in deep water. Determining its chartering price is a complex task, but it is critical to ensure economic viability and the profit of shareholders. The objective of this study is to propose a pricing model for FPSOs chartering. The pricing model was constructed through the elaboration of a cash flow that considers the input values - contract rate and real operating time (uptime) – and the outputs – investment, operational costs, financial costs, and taxes. The definition of cash flow structure was based on several proposals to FPSOs chartering in Brazil and papers published in scientific journals and Congress proceedings. The model allows analyzing different scenarios by varying parameters such as investment and operational costs, and financing conditions. So, it can support the analysis of the FPSO contract price and contribute to the evaluation of charter proposals.

Published: October 2021

To analyze the economic viability of Pelican Lake field, located in Canada, some scenarios using enhanced oil recovery methods were simulated by request of the field operator, Canadian Natural Resources Limited. Surfactant concentrations influence essential characteristics responsible for promoting good recovery, lowering interfacial tension of fluids and aiding oil bank mobility. Considering different polymer and surfactant concentrations in the injection water and using the PumaFlow software, 5 (five) scenarios of fluid injection were simulated. Results show that the oil recovery factor is directly proportional to the concentration of chemical agents. Among the injection tests carried out, the one with the best performance was the case presenting a concentration of 1400 ppm of polymer and 3000 ppm of surfactant in the injected water, allowing a larger oil production from the field. The case presenting the best outcomes had a 50% higher net present value if compared to the water injection case, as well as an increase of 4.85 percent points in the recovery factor. In addition, for each barrel of additional oil produced, only USD 8.18 is spent on chemical agents, which makes it a cost-effective solution to oil production.

With the exploration of marine oil fields in deep and ultra-deepwater regions, the need for studying different methods of well construction has increased. Nowadays, the technique of laying conductive casing by jetting is the most widely used for the starting phase of a well in such conditions. In this scenario, in early layers, where the marine soil is in contact with seawater, this material can present itself as a fine mud, characterizing a cohesive non-drained soil, with low shear strength, being considered a material with viscoplastic behavior. Thus, as such, using fluid rheology to analyze it may represent a valid option; being possible to classify it as a Herschel-Bulkley fluid. The use of computational modeling and numerical simulation represent an alternative to understand the behavior of soil during jetting. In this context, this work focuses on developing a computational modeling of the jetting of marine soil, based on the soil fluid dynamics approach, using computational fluid dynamics (CFD - Computational Fluid Dynamics) software SIMULIA XFLOW, version 2020. This work aims to investigate the deformation in the seabed in response to an incident vertical jet using different drilling fluids, also modeled as viscoplastic materials. Drilling fluids suitable for jetting and a fluid with a higher specific mass were considered. For the proposed modeling of the soil and drilling fluids considered, the main parameters used were the yield point, consistency index, behavior index, and the boundary viscosity. The latter was necessary to implement the modified Herschel-Bulkley model used by the software. Results show that the excavated cavity presented a similar behavior for the drilling fluids suitable for jetting, indicating that the rheology of the drilling fluid does not interfere with the deformation of the soil. However, a significant influence on the profile of the excavated cavity was observed when implementing the drilling fluid of higher specific mass in the jetting, which deformed the soil at greater depths.

Published: October 2021

At this time, traffic congestion is a problem that many big cities face, especially at intersections. Traffic jams at intersections occur a lot because they are caused by the traffic light regulation system that is not in accordance with the traffic light settings which can be changed at any time. The design of the traffic light simulation control program is deviated by four. The program is made with 4 models, namely the all-light flashing model, the flashing yellow light model, and a different one-way model. The current traffic light regulation mostly uses a fixed time setting system where the lights are set to work on a fixed time basis, regardless of the ups and downs of traffic flow. Therefore, offered a detector system (traffic actuated) by utilizing PLC (programmeble logic controller) as a controller. This research is made a simulation tool with PLC Omron. The working process of this tool is in the form of sending input from sensors installed on the road, where this sensor detects the presence or absence of vehicles.
