Published: December 2019

Aim. To analyse the effi ciency of osteoplastic material application in order to reduce the resorption level after tooth extraction in the preimplantation period according to the data of cone beam computed tomography.Materials and methods. The study involved 80 patients who were divided into 4 equal groups depending on the preservation material used. The fi rst group was treated with Cerabone (Botiss, Germany) xenomaterial based on natural bovine bone. Plasma enriched with PRGF growth factors obtained by the BTI Endoret (Spain) technology was used for the patients of the second group. The third group consisted of patients who underwent a socket preservation of the extracted tooth with a powdered autologous dentin matrix (ADM) obtained from their own tooth. In the fourth group, bone-plastic material based on hydroxyapatite with Collapan-L lincomycin hydrochloride (Intermedapatit, Russia) was used to prevent socket resorption. All patients had a cone beam computed tomography of the maxillofacial region before the extraction and 3 months after the preservation in order to evaluate the level of bone resorption. After the installation of dental implants, a comparative assessment of the bone resorption level in the vertical and horizontal directions before tooth extraction and in the preimplantation period was carried out.Results. The smallest level of vertical bone resorption after socket preservation was observed in group 1 (Cerabone) and group 3 (ADM). The median value of the socket resorption level in group 1 was 0.7 mm (8.54 %) in the vertical direction and 0.5 mm (9.45 %) in horizontal measurement as compared to the level of bone tissue before tooth extraction. Similar indicators were observed in the group using an autologous dentin matrix. The vertical decrease in the socket bone tissue was 0.61 mm (7.75 %), horizontal — 0.51 mm (6.2 %). The level of bone resorption was signifi cantly higher using two other materials.Conclusions. The use of three-dimensional radiation research methods allows a comprehensive assessment of the bone tissue volume to be carried out, which in turn determines the choice of the dental implant size, the need for further bone-plastic surgery to increase the width/height of the alveolar ridge. The use of cone beam computed tomography showed that the most optimal results can be obtained by introducing Cerabone material into the socket of the extracted tooth, as well as using the innovative method of preservation with the patient’s own powdered tooth (ADM).

This article seeks to describe that Islam is not just a religion that pays attention to issues of credo and ritual, but it is also a worldview that brings a change for Muslims. As an Islamic way of life, it has an integrated view of physical and non-physical realities. The verses of the Koran are seminal concepts that project an Islamic view of the universe and life which are referred to as Islamic natural views. It has a different view from the views of other religions and civilizations. Conceptually, Islam as a worldview is closely related to all human activities as social, intellectual and religious beings. As a system of belief, thought, and values, it has the power to change the conditions of civilization. So that in history, its presence has been able to generate scientific traditions through the earliest educational institutions known as Madrasas as-Suffah. From this Madrasa ash-Suffah, ashab ash-suffah (scientific community) developed, This scientific community is needed for the emergence of scientific traditions. The existence of this scientific tradition which later generates to major scholars in the fields of Kalam Science, Tafsir, Hadith, Fiqh, Sufism, etc., which in subsequent developments were able to give birth to polymath Muslim scientists, namely scientists who have expertise in various fields of science at once.

Comparison of the effectiveness of preventive systemic administration of antibiotics with topical use of decamethoxin during clean surgical interventions
Authors: Hlaholieva Anastasiia 
Published: December 2019

Introduction. The lack of generally accepted standards of perioperative antimicrobial prophylaxis leads to the inadequate preventive use of antibiotics associated with development of microbial resistance, changes in the natural biota and sensitization of the patient’s body. Prevention of infectious complications after surgery with topical antiseptic is an appropriate alternative to antibiotic prophylaxis. The purpose of this study was to evaluate the efficacy and safety of topical antiseptic prophylaxis of infectious complications with a 0.02 % decamethoxin solution compared to systemic antibiotic prophylaxis with cefuroxime (beta-lactam antibiotics) during clean surgeries.
Materials and methods. In the first group of patients (n = 25), the operative field was treated with decametoxin, the abdominal cavity was irrigated through an irrigator during laparoscopic interventions after trocart placement or with a syringe in case of open surgeries (50–150 ml). In the second group (n = 22), cefuroxime was administered at a single dose of 1.5 g 30 to 60 minutes before surgery. Patients underwent inguinal hernia repair (Lichtenstein and laparoscopic transabdominal preperitoneal repair), thyroidectomy, parathyroidectomy, laparoscopic adrenalectomy, cholecystectomy, cystectomy of the spleen and ovaries for uncomplicated cysts.
Results. Microbiological analysis of the inoculation material taken from the bottom and walls of the surgical wound before suturing (before the wound was treated with an antiseptic agent in the decamethoxin group) revealed no growth of pathological microbiota at clinically significant levels.
Conclusions. The antimicrobial effect of a 0.02 % decamethoxin solution when applied topically during clean surgical interventions is comparable to that of cephalosporin antibiotics. Perioperative antiseptic prophylaxis can reduce the incidence of antibiotic-resistant strains of microorganisms in surgical departments.

Dünya üzerinde insan faaliyetleri ve enerji tüketiminin giderek artmasıyla önemli oranda artış gösteren sera gazları sonucunda küresel iklim değişikliği yaşanmakta ve iklim değişikliğinin küresel sıcaklık artışı, iklimlerde kaymalar, buzulların erimesi, okyanus ve deniz seviyelerinin yükselmesi gibi etkilerinin somut olarak gösterildiği çalışmalar da artmaktadır.İklim değişikliğinin etkisi ile artan sıcaklıklar sonucu kış turizmi merkezlerinin dayandığı temel doğal kaynak olan doğal kar miktarı, kar kalınlığı ve su kaynakları azalma meydana gelmektedir. Güvenlik sıcaklıklarının artması ve kıs yağışlarının azalması kış turizmi faaliyetlerini de olumsuz etkilemektedir. Türkiye İklim Değişikliği Birinci Ulusal Bildirimine göre 2100 yılına kadar kış sıcaklıklarında 2.5–3°C’ye varan artışlar ve kar kalınlıklarında 20 cm’ye varan incelmeler öngörülmektedir. Kıs yağışlarının azalması, kar sezonunun kısalması ve kar kalınlıklarının da azalması ile kış turizmini ve insan sağlığını tehdit eden durumların ortaya çıkması kaçınılmaz görülmektedir.Türkiye için önemli bir ekonomik sektör konumunda olan turizmin çeşitlenmesi ve 12 aya yayılması stratejisi kapsamında birçok kayak merkezine önemli yatırımlar yapılmakta ve kış turizmini geliştirmeye yönelik çalışmalar devam etmektedir. Ancak kış turizmi merkezleri iklim değişikliğinin etkilerinden ciddi anlamda etkilenecek alanlar olduğundan bu konuda yeterli bilgilendirme ve önlemlere ilişkin çalışmaların yapılmasına ihtiyaç vardır.Çalışmanın amacı iklim değişikliği etkilerine karşı kırılganlığı yüksek olan kış turizminin bu değişimlerden nasıl etkileneceğinin ortaya konulması, Türkiye’de seçilen kış turizmi merkezlerinin iklim değişikliğinden etkilenme durumu ve uyum kapasitesi ile dayanıklılığının değerlendirilmesinde hangi ölçütlerin kullanıldığına yönelik bir örnek uygulama ortaya koymaktır. Bu amaçla Türkiye’nin önemli kış turizm merkezlerinden 1850-2200m. yükseklik kuşağında yer alan Bolu Köroğlu Dağı (Kartalkaya) Kış Turizmi Merkezi ile 2200-3176 m. yükseklik kuşağı üzerinde yer alan Erzurum Palandöken Kış Turizmi Merkezi olmak üzere iki kış turizm merkezinin iklim değişikliğine karşı dayanıklılığının seçilen göstergeler ve bunların ağırlıklandırılması yoluyla değerlendirilmesi sağlanmıştır.Yapılan dirençlilik analizi sonucunda yükseklik, coğrafi konum, mikroklimatik özellikler turizm çekicilikleri ulaşım vb. değerlendirildiğinde Erzurum Palandöken Kış Turizmi Merkezinin, dirençliliğinin daha yüksek olduğu bulunmuştur. Sonuçta turizm politikası ve turizm merkezi planlamasında alınacak kararlara altlık oluşturulması hedeflenmekte ve planlama çalışmaları yapılırken iklim değişikliği etkilerinin de dikkate alınması gerektiğine dikkat çekilmektedir.

Determination of Stiffness Characteristics for WWER-1000 Support Components

Published: December 2019

Available approaches to computer justification of safe operation of reactor support components (RSC) are generally presented in the reports justifying RSC lifetime extension at Ukrainian NPPs. The experience of performing such calculations and analyzing the results indicates that there are issues to be improved. Thus, in particular, RSC stress-strain state is not analyzed for all force factors in the available calculations. It is typical for the reports on RSC lifetime extension justification that the strength assessment of the RSC is performed in an axisymmetric formulation (1/30). Meanwhile, a complex asymmetrical load from the main circulation pipelines is not considered, which affects RSC stress-strain state calculations as some stiffness characteristics (horizontal and torsional stiffness) cannot be determined correctly in a 1/30 axisymmetric formulation.
The paper proposes a methodology for determining RSC stiffness in a complete formulation (without applying symmetry conditions), taking into account all geometric features and the interaction between individual structures and nodes of RSC. Thus, for each RSC (support ring, thrust ring, separating bellows), based on geometric features and types of connection to other components, stiffness to be determined to calculate the forces is defined (six for support ring and separating bellows and three for thrust ring respectively). Single loads in the form of forces and moments were imposed on the remote points connected to corresponding RSC surfaces to determine stiffness. This load made it possible to obtain the displacements and rotation angles of the corresponding remote points, which were used to calculate the stiffness characteristics.
The described approach was first used in the calculations performed within justification of KhNPP Unit 1.

Cobalt oxides and/or manganese and their com-position based on cerium and zirconium oxides (CeO2 : ZrO2 = 1:1 mol.%) with a content of up to 20 wt. % are synthesized. Samples of both individual oxides and complex oxide compositions were prepared by precipitation from solutions of am-monia (room temperature) or hexamethylenetet-ramine (80–90 °C) followed by heat treatment. Results of DTA show, that due to the calcination at 400 ° C (2 h), the obtained samples lose 17–22 wt. % corresponding to 2–3.8 molecules of water. According to the X-ray powder analysis, initially are formed hydroxide compounds of cobalt (CoO· xH2O) and manganese (MnO2·yН2О), which, after being heated at 400 °C for 2 hours, are converted into mixed oxides from the composition of Co3O4 and Mn3O4. The average particle size calculated by the Sherer equation is 18–30 nm.
In the study of catalytic activity on the example of the reaction of the hydrogen peroxide decomposition, it was found that the obtained samples from the solution of GMTA show a greater ability to catalytically decompose hydrogen peroxide compared to samples obtained from the ammonia solution. In this case, the catalytic activity of dried samples is twice as high as roasted, regardless of the method of obtaining. Samples of oxide compo-sitions with deposited 5–10 wt. % of Ce–Zr oxides (1:1) exhibit the highest ability to decompose H2O2. In this case, samples of compositions obtained from the solution of GMTA, have a prolonged catalytic action, and when precipitation in the solution of ammonia, the reaction takes place quite actively during 4–5 days.
Compositions formed from co-deposited or mechanically mixed hydroxocompounds of cobalt and manganese with 5 wt. % of CeO2–ZrO2 (1:1) deposited on them have different catalytic activity. In the case of mechanically mixed, it is 30% lower and with subsequent calcination at 400 °C, it is reduced by almost half, and with co-precipitation, the activity is quite high and does not change with heat treatment. In the case of obtaining samples of Co–Mn with Ce–Zr (1:1) deposited on them in excess of 10 wt. % the catalytic activity of the samples dried at 80 °C is equal to the activity of the co-deposited hydroxocompounds of cobalt and manganese and the calcination at 400 °C it reduces it by 30 %.
The best ability for catalysis was found in samples CoO·xH2O + 5 wt. % MnO2·yН2О, СоO×хН2О + 10 wt. % CeO2:ZrO2 and СоO×хН2О–MnO2×yН2О, precipitated with the GMTA solution and dried at 80 °C. The besser catalytic properties revealed a sample of СоО×хН2О + 10 wt. % CeO2:ZrO2, which with-out stirring is capable of decomposing 1.2–1.4 dm3/g of hydrogen peroxide with a rapid reaction and in the experiment the volume of H2O2 reacted was 3.4 dm3/g.
